Characteristics and correlates of asthma knowledge among emergency department users in Harlem.

We constructed a questionnaire to assess asthma knowledge, assessed its psychometric properties, and examined its association with demographic characteristics, psychosocial factors, and disease severity and management in 375 adults following an asthma-related emergency department visit. Overall knowledge was poor but varied widely among respondents. Better knowledge was related to younger age, higher education, and less severe disease. Chance-orientated health locus of control and low self-esteem were associated with lower asthma knowledge. Better knowledge was associated with better disease management. We conclude that asthma education can lead to improved disease outcomes, and psychosocial factors need to be considered when designing interventions for asthma education.

Patterns and predictors of asthma-related emergency department use in Harlem.

STUDY OBJECTIVES: To assess the roles of poor access to care, psychological risk factors, and asthma severity in frequent emergency department (ED) use. DESIGN: A cross-sectional survey. SETTING: Harlem Hospital Center ED and outpatient chest clinic. PARTICIPANTS: Three hundred seventy-five adult residents of Harlem, a predominantly African-American community in New York City. MEASUREMENTS: Asthma severity was assessed by self-reported symptoms using National Asthma Education and Prevention Program guidelines, health-care utilization, and psychometric scales. RESULTS: Respondents with more severe asthma were more likely to have a primary asthma care provider, and to have had more scheduled office visits for asthma in the year prior to the interview (mean number of visits for patients with severe asthma, 3.6 visits; moderate asthma, 2.4 visits; and mild asthma, 1.7 visits). Despite having a regular source of care, 69% of respondents identified the ED as their preferred source of care; 82% visited the ED more than once in the year prior to interview (median, four visits). Persons with moderate or severe asthma were 3.8 times more likely to be frequent ED users compared to those with mild asthma (odds ratio [OR], 3.8; 95% confidence interval [CI], 2.2 to 6.6). This was the strongest predictor of frequent ED use. Other predictors of ED use were number of comorbid disorders (OR, 1.5; 95% CI, 1.1 to 2.1) and self-reported global health in the year prior to the ED visit (OR, 1.8; 95% CI, 1.2 to 2.7). Psychological characteristics were not predictive of frequent ED use when controlling for disease severity. CONCLUSIONS: Frequent ED users present with serious medical conditions. They do not substitute physician care with ED care; they augment it to address serious health needs.

Prevalence of asthma and other allergic diseases in an adolescent population: association with gender and race.

OBJECTIVES: To estimate the prevalence and severity of asthma in an adolescent population by sex and race. METHODS: Cross-sectional, population-based survey of school children. SETTING: Midwestern city experiencing damage from the 1993 Mississippi River flood. PARTICIPANTS: 2,693 children attending grades 7 to 12. MEASUREMENTS: Questions from the International Study of Asthma and Allergies in Childhood (ISAAC). RESULTS: Two thousand six hundred ninety-three children were surveyed, for a response rate of 90%. In this population, 16.4% reported having ever been diagnosed with asthma; 25% reported wheezing in the last 12 months; 32% reported symptoms of rhinitis in the last 12 months; and 22% reported ever having hay fever. The prevalence rate for current asthma was 12.6%. Female students had significantly greater prevalence rates for current asthma (16.4% vs 9.0%, OR = 1.85); ever-diagnosed asthma (18.5% vs 14.3%, OR = 1.36); wheezing > or = 4 times in the last 12 months (12.0% vs 5.6%, OR = 1.95); current rhinitis (38.7% vs 25.4%, OR = 1.73); and hay fever (26.4% vs 18.4%, OR = 1.57). All associations with sex remained significant, except ever-diagnosed asthma, after controlling for other known risk factors in logistic regression. African-Americans had higher prevalence rates than other races with differences reaching statistical significance for ever-diagnosed asthma and current asthma; however, these relationships did not remain significant after controlling for other known risk factors in logistic regression. CONCLUSIONS: Our prevalence rates were similar to those reported by other studies that used the ISAAC questionnaire. Female students reported significantly more asthma, wheezing, rhinitis, and hay fever than male students. Female students also reported more severe symptoms and a greater number of emergency room and hospital admissions.

An evaluation of research training in a large residency program.

OBJECTIVE: Evaluation of a research training program for emergency medicine residents. METHODS: A cross-sectional, descriptive analysis of knowledge and skill acquisition observed following the introduction of a resident research curriculum was performed at a university-affiliated emergency medicine residency program within a large-volume, inner-city hospital. The didactic program was based upon a published SAEM model research curriculum and included tutorials in computer applications for research. Seventeen first-year residents participated in the new curriculum and self-assessment evaluation. The rate of research proposal preparation after curriculum implementation for the 17 course participants was compared with that of 26 historical control subjects from the same residency program. RESULTS: Resident attendance for the sessions, offered twice annually, averaged 82%. Significant self-perceived knowledge gains (p < 0.05) were found in the areas of study design and methods, journal selection, research planning, and two microcomputer application areas. There was a strong correlation between postcourse examination scores for many specific subject areas and attendance at the related sessions. Thirteen of the 17 participants (76%) completed an original (NIH PHS398-formatted) research proposal within four months following the training program, compared with only six of 26 residents (23%) not exposed to such a curriculum in previous years (p < 0.05). CONCLUSION: Residents appeared satisfied with this level of training and made gains in their skills and knowledge of research activities. The rate of preparation of research proposals by course attendees surpassed that of former residents. This educational intervention may augment the standard practice of faculty mentorship of residents and fellows for research knowledge and skill acquisition.

Increasing cervical cancer screening among minority elderly. Education and on-site services increase screening.

Older women participate in cervical cancer screening less regularly than do younger women. As a consequence, more lesions are found in more advanced and less curable stages in older women. Elderly black and Hispanic women have had lower rates of participation in cervical cancer screening than white women. There is a marked, inverse relationship between the stage of cervical cancer at diagnosis and the 5-year survival rate. The rate of cervical cancer screening among older women can be increased by offering education about Pap tests and onsite cervical cancer screening in housing for the elderly.
