Tramadol/acetaminophen or hydrocodone/acetaminophen for the treatment of ankle sprain: a randomized, placebo-controlled trial.

STUDY OBJECTIVE: This randomized, multicenter study compares the analgesic efficacy and safety of tramadol/acetaminophen versus hydrocodone/acetaminophen versus placebo for the treatment of acute musculoskeletal pain caused by ankle sprain. METHODS: Adults were enrolled with ankle sprain with a diagnosis of partial ligament tear, pain visual analog scale score of 50 to 100 mm (0="no pain," 100="extreme pain"), and pain numeric rating scale score of 2 to 3 (0="none," 3="severe"). Patients reported pain intensity on these scales and pain relief (-1="pain worse," 4="complete relief") hourly for 4 hours after the first dose of tramadol/acetaminophen 75 mg/650 mg, hydrocodone/acetaminophen 7.5 mg/650 mg, or placebo, and daily for 5 days, with as-needed dosing. RESULTS: Tramadol/acetaminophen (n=192) and hydrocodone/acetaminophen (n=204) provided greater total pain relief than placebo (n=207; P<.001) during the first 4 hours (mean scores [95% confidence interval (CI)] 6.6 [95% CI 6.1 to 7.1], 6.8 [95% CI 6.3 to 7.3], and 5.4 [95% CI 4.9 to 5.9], respectively; possible range -4 to 16), decreased pain intensity during the first 4 hours, and increased average pain relief on days 1 to 5. No efficacy measure was significantly different between the tramadol/acetaminophen and hydrocodone/acetaminophen groups. Common adverse events included somnolence, nausea, dizziness, and vomiting. CONCLUSION: One or 2 capsules of 37.5 mg tramadol/325 mg acetaminophen and 1 capsule of 7.5 mg hydrocodone/650 mg acetaminophen were well tolerated, had comparable clinical utility, and were more effective than placebo in the management of acute musculoskeletal pain caused by ankle sprain.

Pain in aging community-dwelling adults in the United States: non-Hispanic whites, non-Hispanic blacks, and Hispanics.

UNLABELLED: Racial and ethnic disparities in healthcare persist in the U.S. Although pain is one of the most prevalent and disabling symptoms of disease, only a few studies have assessed disparities in pain in large racially and ethnically diverse, middle- to late aged community samples, thus limiting the generalizability of study findings in broader populations. With data from the 2000 Health and Retirement Study, we assessed the prevalence and impact of pain in a community sample of aging (> or =51 years old) non-Hispanic whites (n = 11,021), non-Hispanic blacks (n = 1,804), and Hispanics (n = 952) in the U.S. Pain, pain severity, activity limitation as a result of pain, comorbid conditions, and sociodemographic variables were assessed. Results showed that pain prevalence was 28%, and 17% of the sample reported activity limitation as a result of pain. Non-Hispanic blacks (odds ratio [OR], 1.78; 99% confidence interval [CI], 1.33-2.37) and Hispanics (OR, 1.80; 99% CI, 1.26-2.56) had higher risk for severe pain compared with non-Hispanic whites. Analyses of respondents with pain (n = 3,811) showed that having chronic diseases (2 comorbid conditions, OR, 1.5; 99% CI, 1.09-2.17), psychological distress (OR, 1.99; 99% CI, 1.54-2.43), being a Medicaid recipient (OR, 1.63; 99% CI, 1.17-2.25), and lower educational level (OR, 1.45; 99% CI, 1.14-1.85) were significant predictors for severe pain and helped to explain racial/ethnic differences in pain severity. PERSPECTIVE: This study, which used a large racially and ethnically diverse community sample, provided empirical evidence that racial/ethnic difference in pain severity in aging community adults in the U.S. can be accounted for by differential vulnerability in terms of chronic disease, socioeconomic conditions, and access to care.

American pain society recommendations for improving the quality of acute and cancer pain management: American Pain Society Quality of Care Task Force.

BACKGROUND: The American Pain Society (APS) set out to revise and expand its 1995 Quality Improvement Guidelines for the Treatment of Acute Pain and Cancer Pain and to facilitate improvements in the quality of pain management in all care settings. METHODS: Eleven multidisciplinary members of the APS with expertise in quality improvement or measurement participated in the update. Five experts from organizations that focus on health care quality reviewed the final recommendations. MEDLINE and Cumulative Index to Nursing and Allied Health Literature databases were searched (1994-2004) to identify articles on pain quality measurement and quality improvement published after the development of the 1995 guidelines. The APS task force revised and expanded recommendations on the basis of the systematic review of published studies. The more than 3000 members of the APS were invited to provide input, and the 5 experts provided additional comments. The task force synthesized reviewers' comments into the final set of recommendations. RESULTS: The recommendations specify that all care settings formulate structured, multilevel systems approaches (sensitive to the type of pain, population served, and setting of care) that ensure prompt recognition and treatment of pain, involvement of patients and families in the pain management plan, improved treatment patterns, regular reassessment and adjustment of the pain management plan as needed, and measurement of processes and outcomes of pain management. CONCLUSION: Efforts to improve the quality of pain management must move beyond assessment and communication of pain to implementation and evaluation of improvements in pain treatment that are timely, safe, evidence based, and multimodal.

Pain assessment instruments for use in the emergency department.

Each patient's pain experience is uniquely his or her own. Standardized pain assessment methodologies and procedures provide a window to this experience and constitute a necessary first step to our understanding of pain, in both clinical and research settings. All too often, emergency department pain assessment is cursory--performed more to satisfy regulatory requirements than to guide our therapies or evaluate our practices. This article provides information on a number of assessment techniques that are appropriate for clinical and research use. Their use should inform our practice and lead to continuous improvements in our management of pain.

Assessing the prevalence of dental caries among elementary school children in North Korea: a cross-sectional survey in the Kangwon province.

OBJECTIVES: The lack of epidemiological studies has made it difficult to assess the extent of public health problems in North Korea. In the absence of empirical data, less intrusive study designs acceptable to the North Korean government could be developed to gauge the public's health. To this end we developed a basic oral health survey in order to assess the prevalence of untreated dental caries among children. METHODS: A cross-sectional survey of 854 elementary school students was conducted in the city of Wonsan, North Korea. Students were screened and classified into one of three states of oral health: no caries, minor caries or severe dental caries. Verbal surveys were concurrently administered on children to collect basic information on oral health behaviours and demographic characteristics. Statistical analyses were performed to determine if any variables were significant predictors of oral health status category. RESULTS: Among the 854 students screened, we found 255 students with no caries (29.9%), 316 students with minor caries (37.0%), and 283 students with severe caries (33.1%). The majority of students (70.1%) screened had dental caries. Almost all of the students (98.5%) claimed to brush their teeth daily and 71.2% of students visited a dentist in the past year. There were no significant predictors of oral health status. CONCLUSIONS: The oral health of children in Wonsan, North Korea is comparable if not slightly better than the oral health status of children of similar age in countries with similar Social-Economic Status (SES). Basic oral health screens are useful to produce a snapshot of general oral health status among children in North Korea and may provide insight as to the general health of these children.

The unequal burden of pain: confronting racial and ethnic disparities in pain.

CONTEXT: Pain has significant socioeconomic, health, and quality-of-life implications. Racial- and ethnic-based differences in the pain care experience have been described. Racial and ethnic minorities tend to be undertreated for pain when compared with non-Hispanic Whites. OBJECTIVES: To provide health care providers, researchers, health care policy analysts, government officials, patients, and the general public with pertinent evidence regarding differences in pain perception, assessment, and treatment for racial and ethnic minorities. Evidence is provided for racial- and ethnic-based differences in pain care across different types of pain (i.e., experimental pain, acute postoperative pain, cancer pain, chronic non-malignant pain) and settings (i.e., emergency department). Pertinent literature on patient, health care provider, and health care system factors that contribute to racial and ethnic disparities in pain treatment are provided. EVIDENCE: A selective literature review was performed by experts in pain. The experts developed abstracts with relevant citations on racial and ethnic disparities within their specific areas of expertise. Scientific evidence was given precedence over anecdotal experience. The abstracts were compiled for this manuscript. The draft manuscript was made available to the experts for comment and review prior to submission for publication. CONCLUSIONS: Consistent with the Institute of Medicine's report on health care disparities, racial and ethnic disparities in pain perception, assessment, and treatment were found in all settings (i.e., postoperative, emergency room) and across all types of pain (i.e., acute, cancer, chronic nonmalignant, and experimental). The literature suggests that the sources of pain disparities among racial and ethnic minorities are complex, involving patient (e.g., patient/health care provider communication, attitudes), health care provider (e.g., decision making), and health care system (e.g., access to pain medication) factors. There is a need for improved training for health care providers and educational interventions for patients. A comprehensive pain research agenda is necessary to address pain disparities among racial and ethnic minorities.

Health care disparities in emergency medicine.

The Institute of Medicine's landmark report, "Unequal Treatment: Confronting Racial and Ethnic Disparities in Health Care," documents the pervasiveness of racial and ethnic disparities in the U.S. health care delivery system, and provides several recommendations to address them. It is clear from research data, such as those demonstrating racial and ethnic disparities in emergency department (ED) pain management, that emergency medicine (EM) is not immune to this problem. The IOM authors describe two strategies that can reduce disparities in EM. First, workforce diversity is likely to result in a community of emergency physicians who are better prepared to understand, learn from, and collaborate with persons from other racial, ethnic, and cultural backgrounds, whether these be patients, fellow clinicians, or the larger medical and scientific community. Given the ethical and practical advantages of a more diverse EM workforce, continued and expanded initiatives to increase diversity within EM should be undertaken. Second, the specialty's educational programs should produce emergency physicians with the skills and knowledge needed to serve an increasingly diverse population. This cultural competence should include an awareness of existing racial and ethnic health disparities, recognition of the risks of stereotyping and biased treatment, and knowledge of the incidence and prevalence of health conditions among diverse populations. Culturally competent emergency care providers also possess the skills to identify and manage racial and ethnic differences in health values, beliefs, and behaviors with the ultimate goal of delivering quality health services to all patients cared for in EDs.

Measuring the dyspnea of decompensated heart failure with a visual analog scale: how much improvement is meaningful?

Patients presenting to the emergency department with heart failure are evaluated based on the subjective sensation of dyspnea. In this study, the authors sought to determine the change in dyspnea, measured by a visual analog scale (VAS), which is associated with a meaningful change in the patient's perception and the effect of dyspnea severity on the VAS. In this prospective, observational study the authors defined a meaningful change in VAS dyspnea as the difference between VAS scores when patients reported "a little less difficulty breathing" or "a little more difficulty breathing." Seventy-four patients were evaluated, and the mean for a meaningful change in VAS was 21.1 mm (95% confidence interval, 12.3-29.9 mm). Patients that recorded higher index VAS scores had a significantly greater change in VAS. VAS scores and the changes with treatment provide the treating physician with another means to assess the effects of their interventions.
