Patient sex and quality of ED care for patients with myocardial infarction.

OBJECTIVE: The aim of the study was to assess the quality of care between male and female emergency department (ED) patients with acute myocardial infarction (AMI). METHODS: A 2-year retrospective cohort study of 2215 patients with AMI presenting immediately to 5 EDs from July 1, 2000, through June 30, 2002 was conducted. Data on patient characteristics, clinical presentation, and ED processes of care were obtained from chart and electrocardiogram reviews. Multivariable regression models were used to assess the independent association between sex and the ED administration of aspirin, beta-blockers, and reperfusion therapy to eligible patients with AMI. RESULTS: There were 849 women and 1366 men in the study. Female patients were older than male patients (74.3 years for women vs 66.8 years for men, P < .001). Among ideal patients, women were less likely than men to receive aspirin (76.3% of women vs 81.3% of men, P < .01), beta-blockers (51.7% of women vs 61.4% of men, P < .01), and reperfusion therapy (64.0% of women vs 72.8% of men, P < .05). However, after adjustment for age, there was no longer a significant relationship between sex and the use of aspirin (odds ratio [OR], 0.99; 95% confidence interval [CI], 0.95-1.03), beta-blockers (OR, 0.94; 95% CI, 0.82-1.04), or reperfusion therapy (OR, 1.01; 95% CI, 0.89-1.09). In models adjusting for additional demographic, clinical, and hospital characteristics, there remained no association between sex and the processes of care. CONCLUSION: Women with AMI treated in the ED have a lower likelihood of receiving aspirin, beta-blocker, and reperfusion therapy. However, this association appears to be explained by the age difference between men and women with AMI. Although there are no apparent sex disparities in care, ED AMI management remains suboptimal for both sexes.

Older emergency department patients with acute myocardial infarction receive lower quality of care than younger patients.

STUDY OBJECTIVE: We assessed the independent relationship between age and the quality of medical care provided to patients presenting to the emergency department (ED) with acute myocardial infarction. METHODS: We conducted a 2-year retrospective cohort study of 2,216 acute myocardial infarction patients presenting urgently to 5 EDs in Colorado and California from July 1, 2000, through June 30, 2002. Data on patient characteristics, clinical presentation, and ED processes of care were obtained from the ED record and ECG review. Patients were divided into 6 groups based on their age at the time of their ED visit: younger than 50 years, 50 to 59 years, 60 to 69 years, 70 to 79 years, 80 to 89 years, and 90 years or older. Hierarchic multivariable regression was used to assess the independent association between age and the provision of aspirin, beta-blockers, and reperfusion therapy (fibrinolytic agent or percutaneous coronary intervention) in the ED to eligible acute myocardial infarction patients. RESULTS: Of ideal candidates for treatment in the ED, 1,639 (80.5%) of 2,036 received aspirin, 552 (60.3%) of 916 received beta-blockers, and 358 (77.8%) of 460 received acute reperfusion therapy. After adjustment for demographic, medical history, and clinical factors, older patients were less likely to receive aspirin (odds ratio [OR] 0.85, 95% confidence interval [CI] 0.77 to 0.93), beta-blockers (OR 0.79, 95% CI 0.71 to 0.88), and reperfusion therapy (OR 0.30, 95% CI 0.18 to 0.52). CONCLUSION: Older patients presenting to the ED with acute myocardial infarction receive lower-quality medical care than younger patients. Further investigation to identify the reasons for this disparity and to intervene to reduce gaps in care quality will likely lead to improved outcomes for older acute myocardial infarction patients.

Adverse cardiac events in emergency department patients with chest pain six months after a negative inpatient evaluation for acute coronary syndrome.

OBJECTIVE: To evaluate the impact of the diagnostic test setting-inpatient versus outpatient-on adverse cardiac events (ACEs) after six months in emergency department (ED) patients with chest pain who were admitted to the hospital and subsequently had a negative evaluation for acute coronary syndrome (ACS). METHODS: The authors retrospectively studied a consecutive sample of ED patients with chest pain over a nine-month period. All patients were admitted to the hospital and underwent negative evaluations for ACS, defined as the absence of diagnostic changes on serial electrocardiograms or cardiac markers (creatine kinase-MB and troponin T), and a negative diagnostic cardiac study. Subjects were classified according to cardiac diagnostic study setting-either inpatient or outpatient. Diagnostic testing included exercise treadmill, angiography, stress echocardiography, or stress thallium scans. Acute cardiac events at six months were defined as cardiac death, myocardial infarction, unstable angina, cardiac arrest, or emergent revascularization. RESULTS: The six-month rate of ACEs among 157 subjects was 14%, with 2% cardiac mortality. The outpatient group had higher ACE risk when compared with the inpatient group using multivariate logistic regression, both for the entire cohort (OR 3.5, p < 0.03) and for a subgroup excluding patients with prior coronary artery disease (OR 6.7, p < 0.05). The outpatient group included 19 of 52 (37%) noncompliant subjects who did not receive a diagnostic study. CONCLUSIONS: Long-term cardiac morbidity of patients after a negative ACS evaluation may be higher than previously thought. Risk of ACE is significantly higher in subjects scheduled for outpatient diagnostic tests. Inpatient diagnostic testing is justified for subjects at risk for poor compliance.

Socioeconomic disparities are negatively associated with pediatric emergency department aftercare compliance.

OBJECTIVES: This study sought to identify demographic, socioeconomic, and clinical predictors of aftercare noncompliance by pediatric emergency department (ED) patients. METHODS: The authors conducted a prospective, observational study of pediatric patients presenting to a university teaching hospital ED from July 1, 2002, through August 31, 2002. Demographic and clinical information was obtained from guardians during the ED visit. Guardians were contacted after discharge to determine compliance with ED aftercare instructions. Subjects were excluded if they were admitted or if guardians were unavailable or unwilling to consent. Data were analyzed using multivariable logistic regression to identify predictors of noncompliance from a list of predetermined variables. RESULTS: Of the 409 patients enrolled in the study, 111 were prescribed medications and 364 were given specific follow-up instructions. Subtypes of the variable "insurance status" were significantly associated with medication noncompliance in multivariable regression analysis. "Insurance status" and "low-acuity discharge diagnoses" were significantly associated with follow-up noncompliance. CONCLUSIONS: Disparity in health insurance has been shown to be a predictor of poor aftercare compliance for pediatric ED patients within the patient population.

Teaching procedural skills to medical students: one institution's experience with an emergency procedures course.

STUDY OBJECTIVE: We examine the effect of a preclinical emergency procedures course on students' clinical procedural skills and medical knowledge. METHODS: This is a retrospective review of evaluation forms for a cohort of 86 students graduating from medical school at an academic center. A cross section of students (n=57) taking a clinical emergency medicine rotation over a 4-year period was also studied. Numeric scores (1 to 9 on a Likert scale) in procedural skills and medical knowledge categories were extracted from evaluations for internal medicine, surgery, obstetrics and gynecology, and emergency medicine rotations. Scores of students who had taken an elective course, Essential Procedures in Emergency Medicine (EPEM), were compared with scores of students who did not take this course. US Medical Licensing Examination Step I scores for both groups were also compared. RESULTS: Students who took EPEM scored significantly higher in the procedural skills category during the emergency medicine rotation (P =.04) and during both months of the internal medicine rotation (P =.02; P =.02). Students scored on average higher in the surgery and obstetrics and gynecology rotations, but these differences were not statistically significant. Students who took EPEM scored significantly higher in the medical knowledge category for emergency medicine (P =.01; P =.002), both months of internal medicine (P =.03; P =.006), and 1 of 2 months of surgery (P =.01) rotations. Students in obstetrics and gynecology rotations scored higher, although not significantly. US Medical Licensing Examination Step I scores were not different between students taking or not taking EPEM. CONCLUSION: Students taking EPEM achieved higher procedural skill and medical knowledge scores in clinical rotations. Emergency medicine is a specialty well suited to study procedures teaching and performance.
