Patient feedback and evaluation measures of a physical activity initiative: Exercise is Medicine program.

BACKGROUND: Nearly half of American adults fail to meet national guidelines for physical activity (PA). As a major contributor to the development of preventable chronic diseases, insufficient PA is an important target for health behaviour interventions. Exercise is Medicine (EIM) aims to increase PA levels among primary care patients through routine PA evaluation, prescription, brief counselling, and referral to community resources. PA is treated as a vital sign with the goal of increasing PA levels in prescribed manageable doses. EIM is currently being implemented in UC San Diego Health System's primary care clinics. OBJECTIVE: (i) To collect and summarize patient perceptions of EIM and its components. (ii) To identify discrepancies between patient-reported feedback and primary care provider (PCP) documentation in corresponding visit notes in the electronic medical record (EMR). METHODS: Patient recall of EIM components was measured using a 10-item survey distributed via MyChart. PCP documentation of EIM was tracked in the EMR system. RESULTS: Patient feedback (n = 316) about EIM components was positive and reinforced patients' confidence in their ability to increase PA. Approximately 70% of patients reported having a PA discussion with their PCP at their most recent visit, but only approximately 21% of these discussions were documented by PCPs using the preprogrammed smartphrase in the EMR. CONCLUSION: Overall, patients reported positive perceptions of EIM. While patient perceptions of EIM suggested that PA discussions with PCPs are happening during the majority of visits, PCP documentation fell behind. Documentation via smartphrase may need to be modified for physicians to use.

The Exercise is Medicine (EIM) program encourages primary care patients to increase their weekly physical activity (PA). The program includes an initial PA evaluation, prescription, counselling, and referral to community resources. EIM is currently active at UC San Diego Health System's primary care clinics. In this study, patient feedback of program components is collected and physician documentation in the electronic medical records system is evaluated. Overall, feedback was positive with patients reporting high levels of self-confidence in their ability to increase their weekly PA. Patients indicated that PA was discussed at roughly 70% of all recent visits. However, physician documentation indicated that PA was discussed at approximately 21% of all recent visits. Although PA was successfully addressed, documentation may need to be modified to more accurately reflect EIM program usage.

Muscle area and density and risk of all-cause mortality: The Multi-Ethnic Study of Atherosclerosis.

BACKGROUND: Lean muscle plays critical roles in physical functioning and metabolism. However, little is known regarding associations between muscle and mortality in adults. OBJECTIVE: The purpose was to evaluate associations between abdominal muscle quantity (area) and quality (density) with risk of all-cause mortality in a diverse cohort free of cardiovascular disease. DESIGN: Data were taken from the Abdominal Body Composition, Inflammation, and Cardiovascular Disease ancillary study of the Multi-Ethnic Study of Atherosclerosis prospective cohort study. Participants were adults (45-85 years) free of extant cardiovascular disease, and of Hispanic, African American, Chinese, or Caucasian descent. Of the original 6814 MESA participants, a random, representative sample (n = 1974) participated in the ancillary body composition study. Abdominal muscle area and density were measured from computed tomography scans spanning L2-L4. Muscle density was measured as attenuation in Hounsfield units, and area was quantified as cm2. Gender-stratified cox proportional hazard models assessed the risk of all-cause mortality across gender-specific quartiles of muscle area and density adjusting for confounders, with area and density entered simultaneously. RESULTS: At baseline, the mean age for men (n = 946) and women (n = 955) was 61.5 and 62.5 years and median follow-up time was 10.6 and 10.9 years, respectively. Muscle density was inversely associated with mortality, with the highest quartile of density showing a 73% reduction in risk for men (HR = 0.27, 95% CI = 0.14-0.51; p-trend<0.001) and 57% reduction for women (HR = 0.43, 95% CI = 0.18-1.01; p-trend = 0.04) compared to the lowest quartile when adjusting for mortality risk factors, lifestyle, BMI and visceral fat. There was no association between muscle area and all-cause mortality for men (p-trend = 0.58) or women (p-trend = 0.47). CONCLUSIONS: Greater abdominal muscle density, but not muscle area, is associated with markedly lower risk of all-cause mortality across a decade of follow up. Muscle quality may be a powerful predictor of mortality in community dwelling adults.
