Early mobilization and accelerated rehabilitation is effective for ankle ligament injury. Squeeze a hole in the inner bag (a), and place the cold pack over the lateral malleolus (b). The cold effect can be prolonged by shaking the cold pack (the foot) once in a while, to mix the chemicals. If the patient needs to move, he should use crutches and bear absolutely no weight on the injured leg. The cold pack is used to provide maximum compression during transport, even if the effect of the cold treatment has subsided (f ). At home, the patient continues compression treatment, wearing an elastic bandage continuously for the first 2 days, preferably with a horseshoe-shaped, foam-rubber pad placed around the malleolus (g). Cooling has a good analgesic effect and may be provided without compression by using running cold water from the tap with the plug in. Special equipment for cold treatment (h), available for most joints, can also be used for this purpose. If an ice pack is used, a thin cloth may be placed under the ice to avoid frostbite. Cold Treatment (Ice) Cooling has traditionally been used in the management of sports injury. There is little consensus on the mode or duration of cold application and there are many recommended treatments including cold water, sprays, ice (crushed or ice cubes), chemical coolant packs, reusable gel packs, and the cryocuff, which combines compression with cooling. Coolant sprays work by evaporation and, while reducing skin temperature, are unlikely to have an effect in the deeper muscle tissue. The physiological response to ice has not been studied in detail and most of the early work was from animal studies. The potential benefits include limitation of bleeding by vasoconstriction, reduction of swelling, limitation of inflammation, slowing the metabolism of local tissues thus reducing hypoxic damage, a local anesthetic effect and pain reduction, and inhibition of local muscle spasm. If ice is used on the field of play the effects on neuromuscular control could possibly increase the risk of further injury or reinjury. Ice can burn the skin if applied directly, and should not be used if it increases pain. Compression Treatment Compression is an integral part of soft-tissue injury management. Empirical evidence and experience supports its use although there are few clinical trials. By increasing resistance, local compression reduces blood extravasation following trauma, and in the absence of major blood loss can reduce bleeding and swelling. One of the few clinical trials in this area showed that compression reduced elevation of creatine kinase following the eccentric exercise and prevented loss of motion, decreased perceived soreness, reduced swelling, and promoted recovery of force production. It is difficult to apply compression to dynamic joints but, more recently, specially designed compression cuffs that mould to the shape of a joint have become available. Compression treatment may be the most important measure in limiting the development of hematoma. If compression increases blood pressure under the bandage to about 85 mmHg, it reduces the blood supply by about 95% within a few seconds. After warm-up an athlete has a blood pressure of about 80 mmHg in the vastus lateralis muscle, but with a tight elastic bandage, blood flow under the bandage may be 0?0% of normal. Reduced blood flow increases linearly with pressure underneath the bandage, so that if the elastic bandage is loosely fit, the blood flow is reduced only by about 60%. Applying a firm pad underneath the compression bandage can increase local pressure over the injury site. Elevation Elevation is based on the principle that confounding the gravitational effect may reduce blood flow and swelling. Early rehabilitation has become increasingly important in recovery from soft-tissue injury and there is less emphasis on rest. Progressive mechanical loading is more likely to restore the strength and morphological characteristics of collagenous tissue. Indeed, early mobilization with accelerated rehabilitation is very effective after acute ankle strain and functional rehabilitation of an ankle sprain, which involves early weightbearing usually with an external support, is better than cast immobilization for most types of sprain severity. Functional rehabilitation encourages recovery-a type of mechanotherapy-whereby mechanical loading prompts cellular responses that promote tissue structural change. The challenge is in finding the balance between loading and unloading during tissue healing. Athletes are particularly vulnerable in endurance sports, where they undertake huge training loads (with respect to frequency, duration, and intensity), and where training may be repetitive (as in long-distance running, cycling, and cross-country skiing). Overuse injury is also a problem in technical sports and team sports, where the same movement is repeated numerous times in training and competition. Repetitive movement may, it has been argued, lead to local tissue overload, and possibly to microrupture. This microdamage requires time to heal but without sufficient time for recovery, injury progresses. The normal adaptive response, which would lead to tissue strengthening, does not occur and there is progressive tissue damage with pain and impaired function. The precipitating factor is often an acute overload-a rapid increase in training load (volume or intensity). Treatment is not just about managing the injury but it is essential to address the risk factors that contributed to the development of the injury. These risk factors can categorized as internal or external factors (also see Chapter 3). A precise understanding of these factors, how they interact, and their relative contribution to the development of the injury allows the athlete and coach to understand what caused the problem, modify training, and eliminate them in the future (Figure 2. Because the injury is the result of overuse, the loading pattern must be altered for treatment to succeed. Once the internal and external factors are successfully modified, the cause of the overuse is removed and, in many cases, the tissue recovers simply because these trigger factors are altered (Figure 2. This treatment may include medication or by aiding the healing process by passive or active modalities. A thorough training history may reveal problems in the training load Document and correct risk such as "too much," "too often," "too factors and training plan soon," or with "too little rest. With overuse, an athlete may have increased the volume or intensity of training too quickly. If they have not been involved in fitness training before, they often start at too high a level and progress too quickly. Many experienced athletes train extremely hard and are continually on the verge of overuse. For such elite athletes it is crucial to maintain the correct balance, training sufficiently to optimize performance yet with sufficient variation to allow recovery. Times when elite athletes are particularly vulnerable include: when athletes intensify their training after a vacation, an illness, an injury, or a pause in training. Injuries are not always caused by increases in training volume but may result from a change in the loading pattern, for example, when new training drills are introduced or when the athlete changes his or her technique. There may be a change in the environment or type of training, for example, when a cross-country skier switches from training in the gym or on roller skis to poling on snow, or when a tennis player shifts from one type of court surface to another. Equipment not properly adjusted and fitted to the specific training may alter the loading pattern that, alone or in combination with other factors, may trigger overuse. Changes in equipment such as footwear in patients with injuries to the lower extremities, rackets, golf clubs, skis, bicycles, and oars may also contribute to the development of injuries. Runners, for example, whether they are sprinters or long-distance runners, experience more muscle and tendon problems in cold climates than in warm climates. Volleyball and basketball players sustain overuse injuries to their knees more easily playing and jumping on hard floors than on softer floors. Runners who introduce hill-climbs may also need to change their running style and reduce the training volume to avoid injuries. Internal Risk Factors Internal risk factors contribute to the etiology of overuse injuries although their relative role and contribution has not been well documented. Despite this, it is generally believed that internal risk factors such as anatomical malalignment, poor skills, or other factors specific to the person should be identified, even though they may be difficult or even impossible to correct. Internal factors alone rarely cause overuse but they may increase the risk of specific tissues overuse, for example, anatomical malalignment in combination with an increase in training load. In one study, internal risk factors were found in 40% of injured runners, but internal risk factors were identified as the trigger in only 10% of the cases. Although malalignment occurs more frequently in runners who sustain overuse injuries, there is little direct evidence that malalignment itself triggers specific injuries. However, it may prevent optimal load distribution and thus overload specific structures or tissues leading to injury. Knowing that the long-distance runner takes about 5000 steps per hour makes it easy to understand how even minor malalignment may cause cumulative abnormal loading of individual structures. To assess alignment, the athlete should be examined both at rest and during loading. High-speed camera recording may be required to uncover alignment during activity, for example, to observe running style. The same degree of malalignment may be of minor importance to a person who runs a few miles for fitness purposes, but apply a significant cumulative load on the tissue of a marathon runner who runs 150?00 km per week. Poor muscle strength or relative muscle balance around a joint may contribute to the development of injury. Some athletes, for example, have weak hamstring muscles ("H," measured during eccentric contraction) relative to the strength of the quadriceps muscles ("Q," measured during concentric contraction), referred to as a low H/Q ratio. This may cause asymmetric loading of the knee or in the muscles close to the knee, a pattern that predisposes to injury. This may occur in an athlete who was previously injured where, with suboptimal rehabilitation, muscle imbalance persists-the patient may have a deviant movement pattern and potentially develop an overuse injury. Inadequate rehabilitation of previous injuries is probably one of the most important risk factors for the development of new injury. A history of previous injury as part of the routine physical examination or periodic health examination may guide interventions to prevent new injury. Athletes with particularly good strength or range of movement, or who have rapidly increased their strength or range of movement, may also be at risk of overuse injury. If a talented javelin thrower rapidly increases their throwing distance, or a high jumper their jumping height after a specific strength-training program, the muscles will adapt quickly. Cartilage, tendons, and ligaments adapt more slowly and are more at risk of injury. If a highly skilled long jumper can develop very high forces during the push-off phase, they are more exposed to overuse injury-due to this innate "neuromuscular" talent-than a person with a slower take-off. In such cases, training should be adjusted to the skills, strengths, and weaknesses of each individual. Short, stiff hip flexor muscles, for example, may cause the pelvis to tilt forward when an athlete extends his hip during high-speed running. This increases the load on the lower part of the lumbar region, leading to back pain during or after the activity. Stretching and elongating the hip flexors may improve of the range of movements and reduce back pain. The athlete should strengthen the muscles around the joint to reduce the direct stress on the joint. Others, such as poor muscle strength, poor mobility, and being overweight, can be changed. Thus, proper rehabilitation is extremely important in the prevention of new injuries. From a practical point of view the most important factor in preventing overuse injury is to correct training errors. Preventing Inactivity Patients who have an overuse injury often reduce their activity level, either on their own or because they have been told to by health care personnel. An important part of treating any injury is to ensure that the healthy parts of the body are kept in shape to allow the athlete to return to sport as soon as possible after recovery. Immobilized muscle tissue loses approximately 10% of its strength within the first 2 weeks, equivalent to 1% of strength and cross-sectional area of the muscle per day of immobilization. Inactivity affects others tissues too, for example, cartilage and ligaments, so inactivity, particularly complete immobilization, must be avoided. Aerobic muscle fibers (Type I fibers) atrophy quickest, and there may be transition between fiber types. Isometric contractions may help counteract the atrophy but cannot prevent it entirely. Electrical stimulation of the musculature may also reduce atrophy but is primarily reserved for situations where voluntary contractions are not possible. Histological changes are visible as early as 6 days after immobilization, with reduced proteoglycan synthesis and aggregation. If this continues, it may lead to osteoarthrosis although the point at which this becomes irreversible is unknown. Early mobilization is key and continuous passive motion is very useful in situations, such as post surgery, where the patient is unable to move the joint on their own. When activity is resumed after a period of non-weight bearing, joint loading should begin with caution to avoid tissue overload.

A depressed fracture caused by a blow to the head from even a relatively small object may cause the bone fragments to impact or tear the dura mater or the brain treatment for dogs with dementia 0.5 mg colchicine mastercard. Basal skull fractures involve the floor of the anterior and middle cranial fossas bacteria generally grow well in foods that order colchicine 0.5 mg overnight delivery. Athletes with a cranial fracture usually have a headache and may or may not have symptoms of an underlying brain injury antibiotic resistance japan cheap 0.5 mg colchicine free shipping. The scalp should be carefully inspected and palpated to establish whether the skull fracture is open or closed infection of the blood colchicine 0.5mg overnight delivery. Rhinorrhea and otorrhea indicate that skull fracture is associated with torn dural membranes antibiotic 294 colchicine 0.5 mg with amex. When a skull fracture is suspected bacteria shape safe colchicine 0.5 mg, the patient should always be hospitalized for observation and neurosurgical evaluation. The physician should cover the injured area of an open cranial fracture with a sterile dressing. Fractures that are depressed beyond the thickness of the inner cranial table often require surgical treatment as do fractures that involve the posterior table of the frontal sinus particularly when there is pneumocephalus. Linear fractures heal in a few months to a year, and if no additional injury occurs, the athlete can often return to her sport. Patients who require a craniotomy to repair a frontal sinus fracture or depressed skull fracture may not be able to participate further in collision or contact sports. Extravasation 72 Head Injuries of blood into the subdural space causes hematoma formation. In addition, subdural hematomas frequently are associated with underlying brain injury, for example, contusions. These injuries are typically seen following falls on hard surfaces or assaults with nondeformable objects rather than low velocity injuries. They are also more common in elderly subjects and should be considered into those taking medications such as anticoagulants. Acute subdural hematomas are the most common traumatic mass lesions and occur in 30% of severely head-injured patients. Chronic subdural hematomas may occur in individuals with brain atrophy and evolve over several weeks even after very mild head injury. Clinical signs and symptoms depend on the size and location of the subdural hematoma and how quickly it developed. In general, the more severe the head injury the more likely the presence of an acute subdural hematoma. There may be a brief period of confusion or loss of consciousness but many patients are in coma from the onset. Soft tissue injuries may be seen at the site of impact but their absence does not mean there is no intracranial injury. Operative treatment is directed toward evacuation of the entire subdural hematoma; control of the bleeding source; resection of contused, nonviable brain or intracerebral hematoma in select patients; and in some patients a decompressive craniotomy. This may performed at the time of initial surgery or in a delayed fashion if further cerebral swelling develops. A chronic subdural hematoma may be removed through only a burrhole in many patients. Acute subdural hematoma usually are associated with underlying injury to the cerebral parenchyma and consequently the prognosis is poor. Patients who require a craniotomy for evacuation of subdural hematoma may not be able to participate further in collision or contact sports. They generally result from head impact in the temporal region that deforms or fractures the skull. The classic presentation is considered a loss of consciousness, recovery of consciousness (lucid interval) then a decline in consciousness. The presentation depends on the size and site of the hematoma, the rate of expansion, and the presence of associated intradural pathology. In these patients contralateral weakness and ipsilateral pupil dilatation are common. Urgent neurosurgical consultation is required when an extradural hematoma is suspected. Rapid diagnosis and prompt surgical evacuation through a craniotomy are indicated when there are neurologic findings and depressed consciousness. Some surgeons advocate hematoma removal even in patients with only a headache when the blood clot is thicker than 15 mm or 30 ml in volume and associated with 5 mm of midline shift. When rapidly treated, the chances of a full functional recovery are excellent even in patients with profoundly abnormal neurological findings before surgery. Generally, patients who require a craniotomy for drainage of an extradural hematoma would not necessarily be precluded from further sports participation assuming full clinical and cognitive recovery. Intracerebral hematomas and contusions are bleeding within the brain substance that appear as mass lesions. Acute traumatic intracerebral hematoma occurs at the time of the initial head injury. Contusions are frequent in the frontal and temporal lobes since this tissue "slides" over the underlying rough bony surface of the skull base during acceleration/deceleration of the head. Penetrating head injury is also associated with intracerebral hematomas and contusions (Figure 4. In many cases, there is a period of confusion or loss of consciousness but only one third of the patients remain lucid throughout their course. Impaired alertness and cognitive function are found frequently on initial examination. When this condition is suspected or diagnosed on imaging studies, an urgent neurosurgical consultation is required. Intracerebral hematomas of >30 ml in volume, >3 cm in diameter, or associated with >5 mm of midline shift should be evacuated. However, the decision to operate depends on many factors, for example, hematoma location, patient age and coagulation status among others. For example, a 20 mL intracerebral hematoma in the temporal lobe may require surgical evacuation. The alert patient with a focal neurologic deficit and a small intracerebral hematoma (<3 cm) particularly those that are in a deep location can be observed closely. Occasionally an intracerebral hematoma may spread into the ventricles and cause intraventricular hemorrhage and hydrocephalus. Patients with an intracerebral hematoma should receive seizure prophylaxis for 7 days unless seizures occur when a longer course is required. The overall recovery depends on what other injuries there are but when there is a small intracerebral hematoma in isolation, particularly in young individuals, recovery is generally good. Patients who require a craniotomy for evacuation of intracerebral hematoma may not be able to participate further in collision or contact sports. Traumatic subarachnoid hemorrhage may occur in isolation but often occurs with other intracranial pathology, in particular subdural hematomas or intracerebral hematoma. In addition traumatic subarachnoid hemorrhage may result from blood vessel injury, for example, a vertebral artery dissection. Subarachnoid hemorrhage typically presents with meningeal symptoms such as headache, neck stiffness and photophobia. The most common initial symptoms of vertebral artery injury causing subarachnoid hemorrhage are neck pain and occipital headache that may precede the onset of neurological symptoms. Traumatic subarachnoid hemorrhage usually is found in a diffuse pattern over the convexities and in the subarachnoid space. When traumatic subarachnoid hemorrhage is suspected or diagnosed on imaging studies, an urgent neurosurgical consultation is required. Vascular imaging may be necessary to exclude a vascular injury particularly when there is penetrating injury or suspected vessel dissection that involves either the carotid or vertebral arteries. There is no specific treatment of traumatic subarachnoid hemorrhage although there is some suggestion that calcium channel antagonists may be useful in some patients. Subarachnoid hemorrhage is associated with the development of vasospasm (delayed narrowing of cerebral vessels) that can contribute to delayed cerebral ischemia. Patients who require a craniotomy for evacuation of hematoma or aneurysmal clipping may not be able to participate further in collision or contact sports. Post-traumatic Epilepsy Post-traumatic epilepsy may occur and is more common with increasing severity of brain injury and in particular intracranial pathology such as hemorrhage or a depressed skull fracture. A convulsing patient is at increased risk of hypoxia that can exacerbate the underlying brain injury. Airway management in these patients is important as is control of oxygenation and blood pressure. Management of post-traumatic seizures is determined by the timing of their occurrence in relation to the head injury. In the absence of a seizure, prophylactic medication can be stopped 7 days after injury since these medications do not prevent the development of post-traumatic epilepsy. If a patient develops further seizures, that is, post-traumatic epilepsy he or she should be managed in the same manner as symptomatic focal epilepsy from any etiology. Post-traumatic Headache Trauma to the head and neck in sport may lead to the development of headache. There are a number of specific subtypes of post-traumatic headaches and these include post-traumatic migraine, extra-cranial vascular headache, and dysautonomic cephalalgia. This disturbing condition often raises fear of serious cerebral injury but tends to resolve over 1? hours. Extracranial vascular headache is periodic headaches at the site of head or scalp trauma. These headaches may share a number of migrainous features, although at times they can be described as "jabbing" pains. Dysautonomic cephalalgia occurs in association with trauma to the anterior triangle of the neck, resulting in injury to the sympathetic fibers alongside the carotid artery. Injuries to the maxillofacial complex account for 3?9% of all sports-related injuries. Approximately 60?0% of these injuries occur in males between the ages of 10?9 years. The incidence of this type of injury varies and is difficult to establish due to the variety of environments and lack of reports. Facial injuries are caused by direct contact between athletes or sport equipment, such as hockey sticks, shoe spikes, goal posts, or railings. The shoulder and upper limb and the head of an opponent are the body parts that most frequently cause injuries to the face. In amateur boxing, ice hockey, bandy, horseback riding, motorcycle sports, martial arts, and American football, mandatory protective equipment has indirectly reduced the number of facial injuries. Athletes in several sports wear mouthguards to prevent dental and orofacial injuries. Differential Diagnoses Soft-tissue injuries including abrasions, lacerations and contusions are the most common sports-related maxillofacial injuries. In this setting, the practitioner must have a high suspicion for facial fractures and dental injuries. However, the expanding use of new sport equipment, such as in-line skates, snowboards, and all-terrain bicycles, has increased the complexity of the injury pattern. The result is that primary caregivers are more frequently confronted with serious injuries. After the initial assessment of airways, breathing and circulation and an evaluation of cervical spine injuries, the examination of the maxillofacial complex may begin. If facial injuries are not treated properly, they may have functional or aesthetic sequelae. Referral to the appropriate specialist and thorough clinical examination is necessary to determine whether a patient with a facial injury needs to be sent for diagnostic imaging to exclude fractures. If the patient has a severe facial injury, the airway may be obstructed by a foreign body, a blood clot, loose teeth, bone or a dislodged mouthguard. Various methods, including nasal tamponade, an epistaxis catheter and compresses in the mouth may be used. Profuse facial bleeding may require intubation, epistaxis catheter, packing of throat and mouth with compresses, compresses over the face and circumfacial elastics to compress the entire maxillofacial complex. Imaging with angiography may be indicated followed by surgery or interventional radiography to control bleeding. The goal of the clinical examination during the acute phase is to evaluate whether there is a soft-tissue injury or a more complex injury that requires treatment by a specialist. If the most important differential diagnoses can be excluded by means of a clinical evaluation, additional examinations for this purpose are unnecessary. The injury mechanism is used as a basis for making the proper diagnosis and for determining the extent of the injury (see Figure 4. In most cases of facial injuries, the injured athlete is able to account for the injury mechanism. Injuries to the oral cavity are often caused by direct trauma to the lips or teeth, caused by a blow or kick from an opposing player or by sport equipment, such as hockey stick, ice hockey puck, bandy ball or a ski pole. Double vision and/or occlusal bite changes are hallmarks of significant facial trauma. A depressed zygomatic complex causes the contour of the cheekbone to become flattened. Injuries in the orbital area may cause changes in the position of the eyeball, such as proptosis (protrusion of the eyeball), hypophthalmos (inferiorly positioned eyeball) and enophthalmos (recessed eyeball), double vision, and reduced ocular movement. A depressed, elongated, widened midface indicates a fracture with dislocation (see Figure 4.
As a result antimicrobial yarn buy colchicine 0.5mg otc, harm associated with use of prescription g m ms d f n opioids affect not onl patients with pain themselves but also their fa a ly w t amilies infection lab values buy cheap colchicine 0.5mg on line, their communiti r ies virus protection program 0.5mg colchicine with mastercard, and socie at large antibiotic prophylaxis for endocarditis order 0.5 mg colchicine visa. Because of these risks nti virus effective 0.5mg colchicine, no widely accepted guideline for opioid prescribing recommends the use of opioids as a first-line therapy for management of chronic noncancer pain antibiotics rash buy colchicine 0.5 mg mastercard. A number of nonopioid pharmacologic treatments can be used successfully to manage pain. While each such alternative has its own indications and risks, there are some circumstances in which nonopioid analgesics. Nonpharmacologic interventions for pain treatment, including acupuncture, physical therapy and exercise, cognitive-behavioral therapy, and mindfulness meditation, also are powerful tools in the management of chronic pain. While further research is needed for some nonpharmacologic interventions to better understand their mechanism of action and optimal frequency and intensity, they may provide effective pain relief for many patients in place of or in combination with pharmacologic approaches. Interventional therapies3 also have been found to be beneficial for the management of some forms of pain. Likewise, progress in preclinical and translational research includes several developments related to the creation of nonaddictive alternatives to the opioid analgesics currently on the market. The movement toward pragmatic, Interventional pain management involves the use of invasive techniques, such as joint injections, nerve blocks, spinal cord stimulation, and other procedures, to reduce pain. The ideal balance of opioid reduction in the context of more comprehensive pain management. Precision medicine (broadly defined) has the potential to improve clinical pain research and management, but is another area in which continued research is needed. In particular, research on the interactions among pain, emotional distress, and reward, including pain-induced alterations in the reward pathway, would help in understanding and reducing the misuse potential of opioids. Studies consistently demonstrate that the risk of overdose increases in a dose-response fashion, that is, with increasing morphine-equivalent milligram doses. It is also important to recognize that people who inject drugs are vulnerable to harms related to drug use that can be reduced by safe access to injection materials. Consider potential effects on illicit markets of policies and programs for prescription opioids. In designing and implementing policies and programs pertaining to prescribing of, access to , and use of prescription opioids, the U. The National Institute on Drug Abuse and the Centers for Disease Control and Prevention should invest in data collection and research relating to population-level opioid use patterns and consequences, especially nonmedical use of prescription opioids and use of illicit opioids, such as heroin and illicitly manufactured fentanyl. Abuse-deterrent formulations are opioid medications designed to reduce the likelihood that they will be "abused. While this approach works well in most cases, the committee believes it is necessary to view regulatory oversight of opioid medications differently from that of other drugs because these medications can have a number of consequences not only at the individual level but also at the household and societal levels. To implement the systems approach proposed by the committee, it will be necessary to broaden the evidence used to demonstrate safety and efficacy during approval and for postmarket monitoring. Specific means for meeting this need may extend beyond the protocolized setting of traditional clinical trials to encompass use of data from less traditional sources, such as online forums. This review should examine whether public health considerations are adequately incorporated into clinical development. The committee believes a commitment to transparency is critical to maintain balance between preserving access to opioids when needed and mitigating opioid-related harms and to maintain public trust. The committee believes this could be accomplished in a relatively short time frame because the review would be limited to a single drug class for which substantial evidence already exists. Food and Drug Administration should develop a process for reviewing, and complete a review of, the safety and effectiveness of all approved opioids, utilizing the systems approach described in Recommendation 6-1. These strategies include those that (1) restrict the lawful supply of opioids, (2) influence prescribing practices, (3) reduce demand, and (4) reduce harm. The committee offers several recommendations based on its review of the evidence regarding the effectiveness of these strategies. The committee believes the restrictions, policies, and practices recommended leave adequate space for responsible prescribing and reasonable access for patients and physicians who believe an opioid is medically necessary. The potential for benefit remains counterbalanced by recent examples of unexpected harm. States and localities also have regulatory authority over the practice of medicine in their jurisdictions unless their actions are preempted by federal action, and they have exercised that authority to stem the opioid epidemic. Overall, although further research is warranted, limited evidence suggests that state and local interventions aimed at reducing the supply of prescription opioids in the community. It should be emphasized, however, that none of these studies investigates the impact of reduced access on the well-being of individuals suffering from pain whose access to opioids was curtailed. The available evidence suggests that drug take-back programs in the United States can increase awareness of the need for the safe disposal or return of many unused drugs, but effects of these programs on such downstream outcomes as diversion and overdose are unknown. International examples and the recent success of a year-round disposal program at one pharmacy chain support policies expanding such programs to reduce the amount of unused opioids in the community. States should convene a public?rivate partnership to implement drug take-back programs allowing individuals to return drugs to any pharmacy on any day of the year, rather than relying on occasional take-back events. Prescribing guidelines may be able to improve provider prescribing behavior, but may be most effective when accompanied by education and other measures to facilitate implementation. Establish comprehensive pain education materials and curricula for health care providers. State medical schools and other health professional schools should coordinate with their state licensing boards for health professionals. Insurance-based policies have substantial potential to reduce the use of specific prescription drugs, although their impact on health outcomes remains uncertain. The judicious deployment of insurer policies related to opioid prescribing would benefit from a commensurate increase in coverage of and access to comprehensive pain management, encompassing both pharmacologic and nonpharmacologic modalities. The committee was struck in particular by the relative lack of attention to the impact of educating the general public (i. Evaluate the impact of patient and public education about opioids on promoting safe and effective pain management. Department of Health and Human Services and state health financing agencies should remove impediments to full coverage of medications approved by the U. Strategies for Reducing Harm Life-saving medication for treating opioid overdose is available. The provision of naloxone to overdose victims by laypersons or health professionals in the prehospital setting is the standard of care, and community-based programs and other first responder agencies have adopted this protocol for treating opioid overdose. Mechanisms for increasing naloxone prescribing and dispensing, equipping first responders, and possibly enabling direct patient access. To reduce the harms of opioid use, including death by overdose and transmission of infectious diseases, states should implement laws and policies that remove barriers to access to naloxone and safe injection equipment by ?permitting providers and pharmacists to prescribe, dispense, or distribute naloxone to laypersons, third parties, and first responders and by standing order or other mechanism; ?ensuring immunity from civil liability or criminal prosecution for prescribers for prescribing, dispensing, or distributing naloxone, and for laypersons for possessing or administering naloxone; and ?permitting the sale or distribution of syringes, exempting syringes from laws that prohibit the sale or distribution of drug paraphernalia, and explicitly authorizing syringe exchange. Trends indicate that premature deaths associated with the use of opioids are likely to climb and that opioid overdose and other opioidrelated harms will dramatically reduce quality of life for many people for years to come. Drug overdose, driven primarily by opioids, is now the leading cause of unintentional injury death in the United States (more than 60 percent of overdose deaths in 2015 involved a prescription or illicit opioid) (Rudd et al. This increase in opioid-related deaths has occurred in tandem with an equally unprecedented increase in prescribing of opioid medications for purposes of pain management. Millions of Americans experience acute and/or chronic painful conditions each year, and many of them are prescribed opioids. Moreover, many lawfully dispensed opioids make their way into the hands of people for whom they were not intended, including participants in illicit markets. Yet, as discussed below, OxyContin was widely diverted, and many people became addicted to it. The approval of this drug exacerbated frustration among some stakeholders that the societal impacts of opioids were not being sufficiently accounted for. The committee also was asked to outline steps that can be taken by other stakeholders. Review the available evidence on best practices with regard to safe and effective pain management, including practices to reduce opioid abuse and misuse, including an assessment of possible barriers to implementation of those best practices by prescribers and patients. Two consultants with expertise in health care and food and drug law were appointed to contribute to the regulatory components of this report. This literature review entailed English-language searches of a number of databases, including the Cochrane Database of Systematic Reviews, Embase, Google Scholar, Medline, PubMed, Scopus, and Web of Science. In addition to research published in peerreviewed journals and books, the committee reviewed reports issued by government agencies and other organizations. In addition, the committee held two public workshops to hear from researchers and agency representatives on topics germane to its task. This proposed terminology is a partial basis for the definitions presented in Box 1-2, which reviews both acceptable language and language that has been identified as no longer acceptable. The severity of a substance use disorder can differ across individuals and across time for the same individual. Different from opioid use disorder and addiction, dependence in this report refers to a state associated with withdrawal symptoms upon cessation of repeated exposure to a drug. It is important to note that a person who is physically dependent on a drug may not meet the definition of addiction. Tolerance refers to the diminishing effect of a drug resulting from the repeated administration of a given dose. Abuse (as in substance abuse or substance abuser) is no longer acceptable terminology, as research has found the term to be associated with negative and stigmatizing perceptions. Accordingly, the committee avoids use of this term except when quoting other sources; when referring to abuse-deterrent formulations of opioids (those with properties designed to prevent misuse [e. The term misuse is commonly used to describe any use of a prescription medication beyond what is directed in a prescription. Some have argued that use of the term "misuse" to encompass both medical and nonmedical motivations (such as "to get high") is misleading and imprecise. Diversion refers to the transfer of regulated prescription drugs from legal to illegal markets. The term is not used in this report to refer to the sharing of drugs with friends, family members, or other contacts for medical or nonmedical purposes. Traditionally, the term opiates refers to substances derived from opium, such as morphine and heroin, while opioids refers to synthetic and semisynthetic opiates. However, the term opioids is now often used for the entire family of opiates, including natural, semisynthetic, and synthetic. This acronym may refer either to medication for addiction treatment, where medications are used without counseling and behavior therapies, or to medicationassisted treatment, where medication is used in conjunction with these therapies. Current medications approved for treatment of opioid use disorder are methadone, buprenorphine, and naltrexone. The terms substitution therapy and replacement therapy are not accurate and therefore are not used in this report. While the use of opioids for treatment of acute severe pain has generally been accepted, their use for managing chronic noncancer pain has been controversial since the 19th century, with the popular view shifting over the decades between broad acceptance and a more restrictive perspective (Rosenblum et al. The tension between the desire to make opioids available to those who may benefit from them and the recognition that opioids are addictive drugs with societal consequences began with medical developments that occurred during the 1800s (Booth, 1986; Musto, 1999; Rosenblum et al. These developments included the extraction of morphine from opium in 1803 and the development of the hypodermic needle (which can be used to inject morphine to relieve neuralgic pain) in the 1850s (Rosenblum et al. With few effective alternatives, moreover, many medical professionals used morphine to treat chronic pain conditions. This and the nonmedical use of opioids were major drivers of an opioid addiction epidemic that took place in the latter 19th century (Courtwright, 2015). What is thought to be the first accurate and comprehensive description of addiction to morphine was produced in 1877. In hopes of developing a less addictive alternative to morphine, heroin (diacetylmorphine) was synthesized in 1874 (although it was later found to be more potent than morphine) (Rosenblum et al. The Harrison Narcotics Act, enacted by Congress in 1914, required persons who imported, produced, sold, or dispensed opium-based drugs (as well as coca-based drugs) to register, pay a tax, and keep detailed records that officials could use in enforcing laws to restrict opioid transactions to legitimate medical channels. This act had the effect of criminalizing the use of opium for nonmedical purposes (Courtwright, 2015; Hoffman, 2016). Research aimed at developing new and potentially less addictive opioids continued, however, and Percocet and Vicodin-which combined semisynthetic opioids with acetaminophen-became available in the 1970s for relief of moderate to moderately severe pain. Purdue claimed in some of its promotional materials that the risk of addiction to the drug was small (Van Zee, 2009). Around the same time, there was growing recognition in the medical community that many individuals with chronic pain were being treated inadequately (Pokrovnichka, 2008). In 1996, the American Academy of Pain Medicine and American Pain Society issued a joint consensus statement titled the Use of Opioids for the Treatment of Chronic Pain, describing potential benefits of using opioids for management of chronic (including noncancer) pain (Haddox et al. Advocates representing the interests of pain patients suggested that pain be considered a "fifth vital sign" in an effort to improve pain assessment and treatment (Campbell, 1996), and some health care organizations incorporated this concept into guidelines and clinical practice (Mularski et al. There were also concerted efforts by pain specialists to persuade state medical boards and state legislatures to remove legal impediments to 3 4 the Harrison Narcotics Act has since been replaced by the Controlled Substances Act, enacted in 1970. These include opioids containing less than 90 milligrams of codeine per dosage unit. Congress declared 2001?011 the "Decade of Pain Control and Research" (Brennan, 2015). However, problems began to emerge around 2000, with reports of widespread diversion, tampering, and misuse of OxyContin (Cicero et al. Data from the National Prescription Audit show that the number of opioid prescriptions dispensed from U. Of these, 60 percent were doctors, pharmacists, or other professionals (Hoffman, 2016).
