Seasonality and coronary heart disease deaths in United States firefighters.

United States firefighters have a high on-duty fatality rate, and coronary heart disease is the leading cause. Seasonality affects the incidence of cardiovascular events in the general population, but its effects on firefighters are unknown. This study statistically examined the seasonal and annual variation of all on-duty coronary heart disease deaths among US firefighters between 1994 and 2004 using the chi-square distribution and Poisson regression model of the monthly fatality counts. It also examined the effect of ambient temperature (apparent as well as wind chill temperature) on coronary heart disease fatalities during the study span using a time-stratified, case-crossover study design. When grouped by season, we observed the distribution of the 449 coronary heart disease fatalities to show a relative peak in winter (32%) and relative nadir in spring (21%). This pattern was significantly different (p=0.005) from the expected distribution under the null hypothesis of season having no effect. The pattern persisted in additional analyses, stratifying the deaths by the type of duty in which the firefighters were engaged at the time of their deaths. In the Poisson regression model of the monthly fatality counts, the overall goodness-of-fit between the actual and predicted case counts was excellent (chi(4)(2)=16.63; p=0.002). Two distinct peaks were detected: one in January-February and the other in August-September. Overall temperature was not associated with increased risk of on-duty death. After allowing for different effects of temperature in mild/hot versus cold periods, a 1 degrees C increase was not protective in cold weather; nor did it increase the risk of death in warmer weather. The findings of this study reveal statistical evidence for excess coronary heart disease deaths among firefighters during winter; however, the temporal pattern of coronary heart disease deaths was not linked to temperature variation. The seasonal pattern was also found to be independent of duty-related risks.

Firefighter heart presumption retirements in Massachusetts 1997-2004.

OBJECTIVE: "Heart Presumption" legislation is common throughout North America. We sought to study Massachusetts firefighters retiring with heart disability awards. METHODS: The authors conducted a retrospective review of Massachusetts firefighters: 362 receiving Heart Presumption pensions (1997-2004) and a comparison group of 310 professionally active firefighters. RESULTS: Of retirements, 77% were due to coronary heart disease and 23% for other cardiovascular conditions. Only 42% of the retirements were related to discrete on-duty events. Fire suppression (odds ratio = 51, 95% confidence interval = 12-223) and alarm response (odds ratio = 6.4, 95% confidence interval = 2.5-17) were associated with markedly higher risks of duty-related heart retirement events than nonemergency activities. Cardiovascular risk factor prevalence was high among all retiree subgroups and significantly greater than among control firefighters in almost all cases. CONCLUSIONS: Our study supports calls for improved cardiovascular prevention and risk reduction strategies among firefighters.

In-training practice patterns of combined emergency medicine/internal medicine residents, 2003-2007.

INTRODUCTION: This study seeks to evaluate the practice patterns of current combined emergency medicine/internal medicine (EM/IM) residents during their training and compare them to the typical practice patterns of EM/IM graduates. We further seek to characterize how these current residents perceive the EM/IM physician's niche. METHODS: This is a multi-institution, cross-sectional, survey-based cohort study. Between June 2008 and July 2008, all 112 residents of the 11 EM/IM programs listed by the Accreditation Council for Graduate Medical Education were contacted and asked to complete a survey concerning plans for certification, fellowship, and practice setting. RESULTS: The adjusted response rate was 71%. All respondents anticipated certifying in both specialties, with 47% intending to pursue fellowships. Most residents (97%) allotted time to both EM and IM, with a median time of 70% and 30%, respectively. Concerning academic medicine, 81% indicated intent to practice academic medicine, and 96% planned to allocate at least 10% of their future time to a university/academic setting. In evaluating satisfaction, 94% were (1) satisfied with their residency choice, (2) believed that a combined residency will advance their career, and (3) would repeat a combined residency if given the opportunity. CONCLUSION: Current EM/IM residents were very content with their training and the overwhelming majority of residents plan to devote time to the practice of academic medicine. Relative to the practice patterns previously observed in EM/IM graduates, the current residents are more inclined toward pursuing fellowships and practicing both specialties.

Effective out-of-operating room airway management for physicians not traditionally trained in airway management.

BACKGROUND: There is a dearth of literature about the safety and practicality of intubation performed by an internal medicine (IM) or any other nonanesthesia, nonemergency physician. OBJECTIVES: The objectives of the study were to describe abbreviated airway management training guidelines for IM physicians staffing the emergency department and to compare the success rates between intubations performed by anesthesia and IM physicians, respectively. METHODS: In this study, 272 consecutive out-of-operating room intubations performed by anesthesia and IM physicians were evaluated after creating and implementing an abbreviated intubation training protocol. RESULTS: Of 165 intubations attempted by IM physicians and 107 intubations attempted by the anesthesia service, the rates of successful intubation were 93% and 99%, respectively (P = 0.02). There were no other statistically significant differences in outcomes. CONCLUSIONS: Procedurally oriented IM fellows could provide a temporary solution to hospitals that currently do not have the resources to provide full-time, in-house anesthesiology or emergency physicians for management of the emergent airway.

Combined residency training in emergency medicine and internal medicine: an update on career outcomes and job satisfaction.

OBJECTIVES: This study was designed to provide an update on the career outcomes and experiences of graduates of combined emergency medicine-internal medicine (EM-IM) residency programs. METHODS: The graduates of the American Board of Emergency Medicine (ABEM) and American Board of Internal Medicine (ABIM)-accredited EM-IM residencies from 1998 to 2008 were contacted and asked to complete a survey concerning demographics, board certification, fellowships completed, practice setting, academic affiliation, and perceptions about EM-IM training and careers. RESULTS: There were 127 respondents of a possible 163 total graduates for a response rate of 78%. Seventy graduates (55%) practice EM only, 47 graduates (37%) practice both EM and IM, and nine graduates (7%) practice IM or an IM subspecialty only. Thirty-one graduates (24%) pursued formal fellowship training in either EM or IM. Graduates spend the majority of their time practicing clinical EM in an urban (72%) and academic (60%) environment. Eighty-seven graduates (69%) spend at least 10% of their time in an academic setting. Most graduates (64%) believe it practical to practice both EM and IM. A total of 112 graduates (88%) would complete EM-IM training again. CONCLUSIONS: Dual training in EM-IM affords a great deal of career opportunities, particularly in academics and clinical practice, in a number of environments. Graduates hold their training in high esteem and would do it again if given the opportunity.
