Increasing Medical Trainees' Empathy Through Volunteerism and Mentorship.

BACKGROUND: Within medical education, there have been recent calls for increased understanding and exposure to poverty to increase trainees' empathy toward the underserved. Students participating in Michigan Cardiovascular Outcomes Research and Reporting Program research program volunteered at World Medical Relief (WMR) in Detroit, Michigan, a nonprofit organization which recycles medical equipment for developing countries and within greater Detroit. Participants' perceptions of the underserved were measured before and after the experience. METHODS: Preliminary questionnaires were given to participants prior to and after exposures at WMR. Questionnaires examined participants' attitudes toward the underserved, knowledge of medical supply reuse, and their perceived ability to impact change. P values of <.025 were considered significant. RESULTS: A total of 39 participants completed the survey, 77% previously volunteered, 33% had volunteered internationally. Participants were >4× more likely than previously to have knowledge of the variety of recycled medical supplies at WMR. Prior to volunteering, 48.7% of participants gave little thought to how excess medical supplies could be collected versus 0% after exposure. Participants were 1.5× more likely to agree that the experience was enhanced working with their peers and 2.7× more likely to consider starting their own organization/intervention for medical supply donations. Those participants that never previously volunteered were 1.3× more likely to do so with encouragement from a mentor. CONCLUSIONS: Encouraging exposure to such service programs resulted in enhanced knowledge of community resources and increased motivation to participate in outreach and belief of individual responsibility to care for the underserved. Incorporating volunteerism into traditional education programs offers the opportunity to build awareness and interest in students reaching out to the underserved.

Use of warfarin for venous thromboembolism prophylaxis following knee and hip arthroplasty: results of the Michigan Anticoagulation Quality Improvement Initiative (MAQI2).

Total knee arthroplasty (TKA) and total hip arthroplasty (THA) are associated with high rates of venous thromboembolism (VTE). Anticoagulants, such as warfarin, are commonly used to prevent VTE in such patients. The practice and effectiveness of warfarin in real world populations is not well documented. 595 TKA and THA patients treated with warfarin were followed by two anticoagulation clinics in the Michigan Anticoagulation Quality Improvement Initiative. Length of prescribed anticoagulation, percent time in therapeutic range (%TTR) and time to first therapeutic INR were calculated for each surgical group. For THA, all 300 patients received at least ten days with a 28-day median length of anticoagulation therapy. For TKA, all 295 patients received at least 10 days with a 28-day median length of anticoagulation therapy. For THA patients, time to first therapeutic INR was on average 12.0 ± 8.0 days with a mean %TTR of 36.6 ± 26.8% for goal INR 2.0-3.0. For THA patients, 39 (13%) never reached target INR. For TKA patients, time to first therapeutic INR was on average 12.8 ± 10.3 days with a mean %TTR of 36.0 ± 28.3% for goal INR 2.0-3.0. For TKA patients, 44 (14.9%) never reached target INR. Many orthopaedic surgeons who use warfarin for post-arthroplasty VTE prophylaxis do so in accordance with national guidelines. The time to first therapeutic INR is strikingly long and %TTR markedly low for these patients, raising questions about the efficacy of warfarin therapy in the first 1-2 post-operative weeks. Further studies to investigate the best target INR for warfarin prophylaxis, as well as the composite rates of VTE and clinically relevant bleeding from treatment with warfarin, LMWH and newer anticoagulants are needed.

Role of cigarette smoking and gender in acute coronary syndrome events.

Cigarette smoking has been associated with lower mortality after an acute coronary event. We hypothesized that the improved survival in smokers is related to demographic differences and sought to further evaluate the gender disparities in smokers after an acute coronary event. A prospective cohort of 3,588 patients hospitalized at a single center from 1999 to 2006 was identified. Smoking status, in-hospital and 6-month follow-up death, and cardiovascular events (i.e., myocardial infarction, stroke, cardiac-related rehospitalization, and unscheduled revascularization) were assessed. The prevalence of smoking in men increased over time. The smokers were younger at presentation with fewer co-morbidities than nonsmokers. Male smokers had lower mortality (3.2% vs 5.4%, p = 0.04) and fewer cardiovascular events (33.1% vs 42.4%, p = 0.003) at 6 months than nonsmokers. However, after adjusting for age and co-morbidities, smoking was not an independent predictor of events (odds ratio 0.88, 95% confidence interval 0.67 to 1.17). Female smokers had mortality (5.6% vs 8.4%, p = 0.15) and cardiovascular events (54.5% vs 49.7%, p = 0.28) at 6 months similar to that of nonsmokers, with a nonsignificant trend toward increased risk after adjustment (odds ratio 1.31, 95% confidence interval 0.90 to 1.93). Among smokers, female gender remained a significant risk factor for cardiovascular events at 6 months (odds ratio 2.35, 95% confidence interval 1.58 to 3.50), even after adjustment for age and co-morbidities. In conclusion, smokers experienced acute coronary event events earlier than did nonsmokers. Younger age and fewer co-morbidities likely account for most observed survival benefit in smokers, although female smokers are more likely to experience cardiovascular complications by 6 months than male smokers.

Childhood obesity: A comparison of health habits of middle-school students from two communities.

OBJECTIVE: To assess whether children's diet and physical activity patterns differ between neighboring communities with differing resources. STUDY DESIGN AND SETTING: We compared the health behaviors of middle-school students in two Michigan communities; Ann Arbor and Ypsilanti; median household income of US$46,299 and 28,610, respectively. Self-reported diet and physical activity habits were collected. PARTICIPANTS: A total of 733 middle-school students from two neighboring communities (five Ann Arbor and two Ypsilanti middle schools) participated in the study. MEASURES: Data on age, gender, and racial/ethnic factors were collected as part of the baseline assessment. Students were also measured for height and weight. Body mass index was calculated. Information on diet and physical activity in addition to amounts and types of sedentary activities was assessed via questionnaires. RESULTS: More Ypsilanti schoolchildren were obese compared to the Ann Arbor schoolchildren (22.2% vs 12.6%; P = 0.01). The Ypsilanti schoolchildren reported higher consumption of fried meats (7.5% vs 3.2%; P = 0.02), French fries or chips (14.3% vs 7.9%; P = 0.02), punch or sports drinks (24.1% vs 12.2%; P = 0.001) and soda (18% vs 7.9%; P < 0.001) compared to the Ann Arbor children. School-based activities including physical education classes (58.6% vs 89.7%; P < 0.001) and sports teams (34.6% vs 62.8%; P < 0.001) differed for Ypsilanti schoolchildren vs Ann Arbor children. Sedentary behaviors were higher in the Ypsilanti children. CONCLUSIONS: Differences in diet and physical activity habits among children from two neighboring communities with varying resources suggests a need for school-based interventions to promote healthy behaviors among middle-school students.
