RESUMO

BACKGROUND: Nesiritide is approved in the United States for early relief of dyspnea in patients with acute heart failure. Previous meta-analyses have raised questions regarding renal toxicity and the mortality associated with this agent. METHODS: We randomly assigned 7141 patients who were hospitalized with acute heart failure to receive either nesiritide or placebo for 24 to 168 hours in addition to standard care. Coprimary end points were the change in dyspnea at 6 and 24 hours, as measured on a 7-point Likert scale, and the composite end point of rehospitalization for heart failure or death within 30 days. RESULTS: Patients randomly assigned to nesiritide, as compared with those assigned to placebo, more frequently reported markedly or moderately improved dyspnea at 6 hours (44.5% vs. 42.1%, P=0.03) and 24 hours (68.2% vs. 66.1%, P=0.007), but the prespecified level for significance (P≤0.005 for both assessments or P≤0.0025 for either) was not met. The rate of rehospitalization for heart failure or death from any cause within 30 days was 9.4% in the nesiritide group versus 10.1% in the placebo group (absolute difference, -0.7 percentage points; 95% confidence interval [CI], -2.1 to 0.7; P=0.31). There were no significant differences in rates of death from any cause at 30 days (3.6% with nesiritide vs. 4.0% with placebo; absolute difference, -0.4 percentage points; 95% CI, -1.3 to 0.5) or rates of worsening renal function, defined by more than a 25% decrease in the estimated glomerular filtration rate (31.4% vs. 29.5%; odds ratio, 1.09; 95% CI, 0.98 to 1.21; P=0.11). CONCLUSIONS: Nesiritide was not associated with an increase or a decrease in the rate of death and rehospitalization and had a small, nonsignificant effect on dyspnea when used in combination with other therapies. It was not associated with a worsening of renal function, but it was associated with an increase in rates of hypotension. On the basis of these results, nesiritide cannot be recommended for routine use in the broad population of patients with acute heart failure.

RESUMO

BACKGROUND: Millions of people seek emergency department (ED) care for injuries each year, the majority for minor injuries. Little is known about the effect of psychiatric co-morbid disorders that emerge after minor injury on functional recovery. This study examined the effect of post-injury depression on return to pre-injury levels of function. METHOD: This was a longitudinal cohort study with follow-up at 3, 6 and 12 months post-injury: 275 adults were randomly selected from those presenting to the ED with minor injury; 248 were retained over the post-injury year. Function was measured with the Functional Status Questionnaire (FSQ). Psychiatric disorders were diagnosed using the Structured Clinical Interview for DSM-IV-TR disorders (SCID). RESULTS: During the post-injury year, 18.1% [95% confidence interval (CI) 13.3-22.9] were diagnosed with depression. Adjusting for clinical and demographic covariates, the depressed group was less likely to return to pre-injury levels of activities of daily living [odds ratio (OR) 8.37, 95% CI 3.78-18.53] and instrumental activities of daily living (OR 3.25, 95% CI 1.44-7.31), less likely to return to pre-injury work status (OR 2.37, 95% CI 1.04-5.38), and more likely to spend days in bed because of health (OR 2.41, 95% CI 1.15-5.07). CONCLUSIONS: Depression was the most frequent psychiatric diagnosis in the year after minor injury requiring emergency care. Individuals with depression did not return to pre-injury levels of function during the post-injury year.

RESUMO

OBJECTIVE: Morphine is a long-standing therapy in acute decompensated heart failure (ADHF), despite few supporting data. A study was undertaken to compare the outcomes of patients who did and did not receive morphine for ADHF. METHODS: The study was a retrospective analysis of the Acute Decompensated Heart Failure National Registry (ADHERE) which enrols hospitalised patients with treatment for, or a primary discharge diagnosis of, ADHF. Patients were stratified into cohorts based on whether or not they received intravenous morphine. ANOVA, Wilcoxon and chi(2) tests were used in univariate analysis, followed by multivariate analysis controlling for parameters previously associated with mortality. Analyses were repeated for ejection fraction subgroups and in patients not on mechanical ventilation. RESULTS: There were 147 362 hospitalisations in ADHERE at December 2004, 20 782 of whom (14.1%) received morphine and 126 580 (85.9%) did not. There were no clinically relevant differences between the groups in the initial age, heart rate, blood pressure, blood urea nitrogen, creatinine, haemoglobin, ejection fraction or atrial fibrillation. A higher prevalence of rest dyspnoea, congestion on chest radiography, rales and raised troponin occurred in the morphine group. Patients on morphine received more inotropes and vasodilators, were more likely to require mechanical ventilation (15.4% vs 2.8%), had a longer median hospitalisation (5.6 vs 4.2 days), more ICU admissions (38.7% vs 14.4%), and had greater mortality (13.0% vs 2.4%) (all p<0.001). Even after risk adjustment and exclusion of ventilated patients, morphine was an independent predictor of mortality (OR 4.84 (95% CI 4.52 to 5.18), p<0.001). CONCLUSIONS: Morphine is associated with increased adverse events in ADHF which includes a greater frequency of mechanical ventilation, prolonged hospitalisation, more ICU admissions and higher mortality.

RESUMO

OBJECTIVES: To describe the presenting characteristics and risk stratification of patients presenting to the emergency department with chest pain who have a normal initial troponin level followed by a raised troponin level within 12 h (evolving myocardial infarction (EMI)). METHODS: Data from the Internet Tracking Registry for Acute Coronary Syndromes (i*trACS), a registry of patients presenting with undifferentiated chest pain, were used. This analysis included patients without ST segment elevation with at least two troponin assay results < or = 12 h apart. Patients were stratified into three groups: EMI (initial troponin assay negative, second troponin assay positive), non-ST elevation myocardial infarction (NSTEMI) (initial troponin assay positive) and no MI (all troponin assays negative). RESULTS: Of 4136 eligible patients, 5% had EMI, 8% had NSTEMI and 87% had no MI. Patients with EMI were more similar to those with NSTEMI than those with no MI with respect to demographic characteristics, presentation, admission patterns and revascularisation. The initial ECG in patients with EMI was most commonly non-diagnostic (51%), but physicians' initial impressions commonly reflected MI, unstable angina or high-risk chest pain (76%). This risk assessment was followed by a high rate of critical care admissions (32%) and revascularisation (percutaneous coronary intervention 17%) among patients with EMI. CONCLUSION: Patients with EMI appear similar at presentation to those with NSTEMI. Patients with EMI are perceived as being at high risk, evidenced by similar diagnostic impressions, admission practices and revascularisation rates to patients with NSTEMI.

RESUMO

OBJECTIVES: We compared the predictive properties of P-selectin to creatine kinase, MB fraction (CK-MB) for detecting acute myocardial infarction (AMI), acute coronary syndromes (ACS) and serious cardiac events upon emergency department (ED) arrival. BACKGROUND: Practioners detecting early diagnosis of ACS have focused on cardiac markers of myocardial injury. Plaque rupture/platelet aggregation precedes myocardial ischemia. Therefore, markers of platelet aggregation may detect ACS earlier than cardiac markers. METHODS: Consecutive patients with potential ACS presenting to an urban university ED were identified by research assistants who screened all ED patients between November 12, 1997 and January 31, 1998. Whole blood was drawn at presentation and 1 h later and rapidly stained and fixed for membrane P-selectin assay and plasma was separated for soluble P-selectin assay. Creatine kinase, MB fraction values were determined using standard immunoassay techniques. Clinical history and hospital course were followed daily. Outcomes were AMI, ACS (AMI and unstable angina) and serious cardiac events. Receiver operator characteristic curves were derived for CK-MB, and soluble and membrane-bound P-selectin to determine the optimal cutoff values. Predictive properties were calculated with 95% confidence intervals. RESULTS: A total of 263 patients were enrolled. They had a mean age of 56.5+/-14 years; 52% were male. There were 22 patients with AMI; 87 patients with ACS and 54 patients with serious cardiac events. Creatine kinase, MB fraction had a higher specificity for detection of AMI, ACS and serious cardiac events than both soluble and membrane-bound P-selectin. At the time of ED presentation, the specificity of CK-MB, and soluble and membrane-bound P-selectin for AMI was 91% versus 76% versus 71%; for ACS, 95% versus 79% versus 71%, and for serious cardiac events, 91% versus 76% versus 72% (p < 0.05). The sensitivities for AMI were 50% versus 45% versus 32%; for ACS, 26% versus 35% versus 30%, and for serious cardiac events, 29% versus 35% versus 36%. CONCLUSIONS: Although theoretically attractive, the use of soluble and membrane-bound P-selectin for risk stratification of chest pain patients at the time of ED presentation does not appear to have any advantages over the use of CK-MB.

RESUMO

BACKGROUND: Although a large interarm blood pressure difference is assumed to help identify patients with aortic dissection, the degree of normal interarm blood pressure variation has not been well defined. METHODS: To determine the normal variation in bilateral upper-extremity blood pressure measurements, we conducted a prospective observational study on a convenience sample of ambulatory patients who were seen at a university hospital emergency department. Bilateral upper-extremity blood pressure measurements were performed with an automated blood pressure monitor at the time the patient was seen. Clinical and demographic data collected included age, sex, race, medical history, chief complaint, cardiac risk factors, pulse, bilateral blood pressure measurements, and discharge diagnosis. The primary outcome measures were the interarm blood pressure differences. RESULTS: Of 610 patients, 324 (53%) had a systolic or a diastolic interarm blood pressure difference of more than 10 mm Hg, and 113 (19%) had a systolic or a diastolic interarm blood pressure difference of more than 20 mm Hg. The variation in interarm blood pressure measurements was unrelated to age, gender, race, mean arterial pressure, cardiovascular risk factors, or discharge diagnosis. The mean interarm systolic blood pressure difference was significantly greater in patients with known coronary artery disease (14.5 vs 10.4 mm Hg; P = .05, Student t test). CONCLUSION: Bilateral upper-extremity blood pressure determinations, as measured by automated indirect measurement, have a wide degree of interarm variation.

RESUMO

BACKGROUND: Patients with myocardial ischemia may have different dispositions and/or pharmacologic interventions based on whether they have recently used cocaine. OBJECTIVE: To determine the prevalence of assessment of cocaine use in patients with acute chest pain syndromes. METHODS: In phase 1 of the study, we reviewed the medical records of all patients with chest pain who presented to the emergency department during February 1996 to assess historical documentation of the presence or absence of cocaine use. In phase 2, we evaluated whether cocaine questions were asked but not documented. After hospital admission, patients were interviewed to see if they were asked about cocaine use. In phase 3, we evaluated possible recall bias by using standardized questioning in the emergency department and used subsequent interviews to assess recall. Assessment of other cardiac risk factors served as the comparison group. RESULTS: In phase 1, 129 charts were reviewed, 13% of which revealed myocardial infarction. The presence or absence of cocaine use (13%) was less frequently documented than the presence or absence of hypercholesterolemia (58%), hypertension (82%), smoking (90%), diabetes (73%), or family history (77%) (chi 2, P < .05 for all comparisons). In phase 2, 27 (31%) of the 86 patients who were interviewed recalled cocaine questioning. There was chart documentation of the cocaine questioning in only 44% of the 27 cases. In phase 3, while in the emergency department, 20 patients were asked about cocaine use: 19 (95%) recalled being asked about cocaine use when interviewed the next day. CONCLUSIONS: Patients with chest pain often are not asked about recent cocaine use. When they are asked, their answers are poorly documented. These findings cannot be explained by poor recall. In cases of chest pain, efforts to improve questioning of patients about cocaine use are needed, since recent cocaine use may change treatment, disposition, and need for counseling.

RESUMO

BACKGROUND: The frequency of complications in patients with cocaine-associated myocardial infarction is unknown. This study was performed to determine the short-term morbidity and mortality secondary to cocaine-associated myocardial infarction. METHODS: We performed a retrospective cohort study at 29 hospital centers throughout the United States. Patients with cocaine-associated myocardial infarction that occurred between 1987 and 1993 were identified through record review. The primary outcome measures were in-hospital mortality and the incidence and timing of major cardiovascular complications. RESULTS: Cocaine-associated myocardial infarction was identified 136 times in 130 patients. Patients were generally young (mean age, 38 years), nonwhite (72%), tobacco smokers (91%) with a history of cocaine use in the past 24 hours (88%). The initial electrocardiogram disclosed infarction in 44% and ischemia in an additional 18% of patients. Myocardial infarctions were evenly distributed between anterior (45%) and inferior (44%) and were most often non-Q-wave (61%). Complications occurred 64 times in 49 patients (36%; 95% confidence interval, 28% to 44%), including congestive heart failure in nine patients, ventricular tachycardia in 23 patients, supraventricular tachycardia in six patients, and brady-dysrhythmias in 26 patients. Most patients who had complications (90%) had them within 12 hours of presentation. Acute in-hospital mortality was 0% (95% confidence interval, 0% to 2%). CONCLUSIONS: The mortality of patients hospitalized with cocaine-associated myocardial infarction was low. The majority of complications occurred within 12 hours of presentation.

RESUMO

Aortoesophageal fistula (AEF) is a relatively rare but life-threatening cause of upper gastro-intestinal bleeding. The clinical characteristics of AEF are so unique that a presumptive bedside diagnosis can be made at the time of presentation. In the past decade, surgical management has improved to the point that cure is now possible. For these reasons, we have reviewed the literature. We summarize our findings with respect to the etiology and clinical characteristics of AEF. Further, we discuss the diagnostic modalities that may be used to confirm the diagnosis, and the therapeutic modalities available to slow the hemorrhage, so as to allow time to correct the anatomic defect.

RESUMO

PURPOSE: To identify clinical criteria predictive of underlying coronary artery disease in patients with cocaine-associated myocardial infarction. PATIENTS AND METHODS: Using a retrospective cross-sectional study design at 29 acute care hospitals, we identified 70 patients with cocaine-associated myocardial infarction who had a determination of the presence or absence of coronary artery disease. Clinical characteristics of patients with coronary artery disease (> 50% stenosis on cardiac catheterization or reversible ischemia on stress test) were compared with patients without coronary artery disease (< 50% stenosis on cardiac catheterization). RESULTS: Compared with patients without coronary artery disease (n = 21), patients with coronary artery disease (n = 49) were older (42 versus 31 years; P < 0.001), had more traditional cardiac risk factors (2.3 versus 1.5; P < 0.001), more frequent history of hypertension (odds ratio [OR], 5.3; 95% confidence interval [CI], 1.4 to 20.4); more frequent family history of myocardial infarction (OR, 4.4; 95% CI, 1.3 to 15.1), more bradydysrhythmias (OR, 8.0; 95% CI, 1.0 to 65.5), and more likely to have an inferior infarct location (P = 0.04). CONCLUSION: Age, number of cardiac risk factors, location of myocardial infarction, and bradydysrhythmias predict underlying coronary artery disease in patients with cocaine-associated myocardial infarction. If validated, this knowledge may be used to develop a medically appropriate, cost-effective evaluation strategy for patients following cocaine-associated myocardial infarction.

RESUMO

OBJECTIVE: To determine the safety of thrombolytic use in patients with cocaine-associated myocardial infarction. DESIGN: Retrospective cross-sectional survey. SETTING: Twenty-nine acute care institutions. PATIENTS: Patients who sustained cocaine-associated myocardial infarction from 1987 to 1993 were identified through medical record review. Those who received thrombolytic therapy (n = 25) were compared with those who met electrocardiographic TIMI criteria but did not receive thrombolytic therapy (n = 41). INTERVENTIONS: None. RESULTS: Both groups of patients were similar with respect to age, gender, race, cardiac risk factors, time from last cocaine use until presentation, and duration of chest pain at the time of presentation (p > 0.20). There were no major complications or deaths in patients who received thrombolytic therapy (95% confidence interval, 0 to 12%). Minor complications occurred in only two patients. The presence or absence of clinical criteria for reperfusion was noted in the charts of 21 patients who received thrombolytic therapy: 67% were believed to reperfuse. The patients who did and did not receive thrombolytic therapy had similar median peak creatine kinase-MB (CK-MB) levels (180 vs 154 mg/dL, p = NS) and time until peak CK-MB (11.3 vs 13.6 h; p = NS). CONCLUSION: Thrombolytic therapy for cocaine-associated myocardial infarction appears to be safe. It remains unclear whether thrombolytic therapy is an important therapeutic intervention for patients with cocaine-associated myocardial infarction. Further study on efficacy is recommended prior to routine use.

RESUMO

The Cardiac STATus CK-MB/Myoglobin device is highly sensitive and has a high negative predictive value within 3 hours of patient presentation. The device may play a role in the re-triage of patients from the CCU to less intensive settings, resulting in a net cost savings.

RESUMO

OBJECTIVE: To evaluate the 3-month cosmetic outcome following laceration repair with a new tissue adhesive, 2-octylcyanoacrylate, as a function of physician experience with this tissue adhesive. METHODS: The authors prospectively enrolled consecutive patients >1 year of age with non-bite, non-crush-induced lacerations who presented <6 hours after injury and were treated with 2-octylcyanoacrylate. Structured closed-question data sheets were completed at the time of laceration repair and at 3-month follow-up. Long-term cosmetic appearance (>3 months) was assessed by patients using a 100-mm visual analog scale. The cosmetic outcomes were evaluated as a function of the physician application using ANOVA or chi2 tests, as appropriate. This study had 80% power to detect a 10-mm difference between the 2-octylcyanoacrylate and suture groups (alpha, 0.05). RESULTS: Seven physicians applied 2-octylcyanoacrylate to 63 patients; 61 patients received sutures. Patients were similar in the 2 groups (age, gender, race, history, and wound characteristics; p > 0.05 for all). At long-term follow-up, the cosmetic outcomes were similar in the 2-octylcyanoacrylate and suture groups according to patients (VAS 83.8 +/- 19.4 mm vs 82.5 +/- 17.6 mm; p = 0.72) and physicians (optimal score, 77% vs 80%; p = 0.67), and independent of physician experience with the 2-octylcyanoacrylate. One wound developed an infection and one wound necessitated reclosure due to dehiscence. Neither occurred with the first application. CONCLUSIONS: The 3-month cosmetic appearance of wounds treated with 2-octylcyanoacrylate is equivalent to that with sutures and does not improve as physicians become more experienced with use of this tissue adhesive. These data suggest that physicians can develop competence in application of tissue adhesives with a brief training period.

RESUMO

OBJECTIVE: To compare the levels of infiltration pain and local anesthetic effects of plain and buffered 1% diphenhydramine. METHODS: A prospective, randomized, double-blind, paired study was performed using 30 adult volunteers. Intradermal injections (0.5 mL) of plain and buffered 1% diphenhydramine were made in the subjects' forearms, one in the left and the other in the right. The pain of infiltration was recorded on a previously validated 10-cm visual analog scale (VAS). The volunteers also were asked which injection was less painful. Sequential measurements of the diameter of anesthesia to pinprick were made at 1, 2, 5, 10, 15, 20, 25, and 30 minutes. The VAS scores and anesthetic diameters were compared for plain and buffered diphenhydramine using a paired Wilcoxon rank sum test. RESULTS: There was no statistically significant difference between buffered diphenhydramine and plain diphenhydramine for pain of injection (23.5 +/- 19.2 mm vs 28.2 +/- 18.7 mm, p = 0.24). Repeated-measures analysis of variance for anesthetic diameters demonstrated no significant difference between buffered diphenhydramine and plain diphenhydramine (p = 0.87). At no single measurement period were the anesthetic diameters different. CONCLUSIONS: In a study with a sample size large enough to detect an 11-mm difference in VAS scores (power = 80%), no difference was found in pain of infiltration and anesthetic effects when plain 1% diphenhydramine was compared with buffered 1% diphenhydramine. Buffering of diphenhydramine does not appear to result in a clinically significant reduction in the pain of infiltration.

RESUMO

An educational program that teaches undergraduate students about clinical research related to emergency medicine is described. The students work as research assistants within the ED, thus providing a departmental framework for the enrollment of patients in clinical studies. Volunteers interested in the program undergo a physical examination, vaccination history, and standard serologic testing, and sit through a formal blood and body fluid exposure course offered by the university prior to their clinical research participation. A didactic curriculum on clinical research concepts and course examinations is provided. Over the 4 years since the department established its departmental research goals and this educational program, the departmental publication rate has increased from 2 to 20 manuscripts. While there was only 1 faculty member with a research publication in 1992, there were 9 faculty with manuscripts accepted for publication in the first 6 months of 1996. Similarly, more nurses and ancillary staff have become involved in prospective clinical research. Much of this success is attributed to the novel use of resources through the academic associate program.

RESUMO

Clinical outcomes measure patient health or well-being. The choice of an outcome measure for use in a clinical trial or study is complex. It is even more difficult when no appropriate outcome measure exists, necessitating the development of a novel one. The ideal clinical outcome should be credible, comprehensive, sensitive to change, accurate, biologically sensible, and feasible. This paper describes the attributes of clinical outcomes and illustrates how to develop novel outcomes, using as an example the authors' experience in developing a wound cosmesis outcome measure.

RESUMO

OBJECTIVE: Suturing of bite wounds remains controversial. The authors evaluated the incidence of wound infection in 145 mammalian bite wounds treated with primary closure. METHODS: Consecutive patients with bite wounds receiving primary closure at a university hospital ED had structured closed-question data sheets completed at the time of wound management and suture removal. Infection was determined at the time of suture removal using a previously validated definition. Data included demographics; medical history; time from injury to evaluation; wound characteristics and location; details of wound cleansing methods, debridement, foreign body removal, and wound closure methods; use of antibiotics; and follow-up wound evaluation. Proportions and 95% confidence intervals were calculated. RESULTS: One hundred forty-five mammalian bite patients were enrolled: 88 dog, 45 cat, and 12 human bites. Patients had a mean (+/-SD) age of 21 +/- 20 years; 58% were male; 86% were white; and they presented a mean (+/-SD) of 1.8 +/- 1.2 hours after injury. Bites occurred on the head and neck (57%), upper extremity (36%), and lower extremity (6%). Wounds had a mean length and width of 2.5 cm and 4.8 mm, respectively. Twelve percent involved structures deep to subcutaneous tissue. After primary wound closure, wound infections occurred in eight patients (5.5%; 95% confidence interval = 1.8% to 9.2%). CONCLUSIONS: The data suggest that carefully selected mammalian bite wounds can be sutured with approximately a 6% rate of infection. This infection rate may be acceptable in lacerations where cosmesis is a primary concern.

RESUMO

OBJECTIVE: Previous studies have shown that contacting an on-line medical-control physician increases the transport rate of patients who attempt to refuse medical assistance. The authors studied the physician-patient interaction to determine the type of interaction that was more likely to result in patient transport. METHODS: A prospective, observational study of patient-initiated refusals of medical assistance (RMAs) was performed in a suburban volunteer emergency medical services (EMS) system, with 12 receiving hospitals county-wide. Medical-control contact was required for all patient-initiated RMAs. Consecutive patients who attempted out-of-hospital RMA over a 3-month period were monitored. Structured data instruments were completed by the medical-control operator and medical-control physician for all patients who attempted RMA. Data collected included patient demographics and contact information, scene characteristics, history and physical examination data, length of time of interaction, and the physician's assessment of the need for transport and the patient's capacity to refuse transport. The operator and physician independently graded the physician's assertiveness in talking to the patient on a continuous 10-point scale. RESULTS: There were 130 patients who attempted RMA; 69 (53%) refused transport even after discussion with the medical-control physician, while 61 (47%) were transported to a hospital. The patients who were transported did not differ from those not transported with respect to age, chief complaint, vital signs, or presence of police on scene. Using the operators' independent assessments, the physicians were more assertive when they graded the patient as being more ill (needs transport, 8.8; may need transport, 7.7; doesn't need transport, 4.1; p < 0.01). When the physicians were more assertive, the patients were more likely to agree to transport (assertiveness > 8, 81% transport; assertiveness < 8, 19% transport; p < 0.01). CONCLUSIONS: Contact with a medical-control physician appears to markedly improve the transport rate for patients who initially attempt to refuse out-of-hospital medical care. This is especially so when physicians are more assertive in recommending transport.

RESUMO

INTRODUCTION: Existing cosmetic scales for wounds are based only on practitioners' evaluations. They have not been validated using the patient's assessment. OBJECTIVE: To validate a previously developed wound cosmesis scale by determining the relationship between patient and practitioner assessments of cosmetic outcome following traumatic wound repair. METHODS: A convenience sample of patients with lacerations repaired in an ED were evaluated at the time of suture removal. Practitioners assigned 0 or 1 point each for the presence or absence of a step-off of borders; contour irregularities; margin separation; edge inversion; excessive distortion; and overall appearance. A total cosmetic score was calculated by adding the categories above. As previously defined, a score of 6 was considered optimal; < 6 was considered "suboptimal." Patients, blinded to the physician score, assessed their degrees of satisfaction with the cosmetic outcome of the wounds using a 100-mm visual analog scale (VAS). Because VAS scores were not normally distributed, practitioner scores were compared with patient satisfaction scores using a Mann-Whitney U test. RESULTS: 125 patients were enrolled, of whom 64% were male; the median age was 19.5 years (interquartile range = 8-33 years). Wounds were located predominantly on the face, scalp, or neck (47%) and upper extremity (35%), and had a median length of 2 cm. The 86 lacerations given optimal practitioner scores had a median patient satisfaction score of 97 mm; the 39 "suboptimal" lacerations had a median patient satisfaction score of 87 mm (p = 0.0006). CONCLUSION: Lacerations that practitioners considered to have optimal cosmetic appearances at the time of suture removal received higher patient satisfaction scores than did lacerations considered to be suboptimal. This provides a measure of validity to this 6-item categorical cosmetic scale.
