Objective: To develop a technology-based method for evaluating the nutritional quality of chain-restaurant menus to increase the efficiency and lower the cost of large-scale data analysis of food items.

Design: Using a Modified Nutrient Profiling Index (MNPI), we assessed chain-restaurant items from the MenuStat database with a process involving three steps: (i) testing 'extreme' scores; (ii) crowdsourcing to analyse fruit, nut and vegetable (FNV) amounts; and (iii) analysis of the ambiguous items by a registered dietitian.

Results: In applying the approach to assess 22 422 foods, only 3566 could not be scored automatically based on MenuStat data and required further evaluation to determine healthiness.

Under the Affordable Care Act (ACA), Medicare coverage expanded in 2011 to fully cover annual preventive care visits. We assessed the impact of coverage expansion, using 2007-13 data from primary care patients of Medicare-eligible age at the Palo Alto Medical Foundation (204,388 patient-years), which serves people in four counties near San Francisco, California. We compared trends in preventive visits and recommended preventive services among Medicare fee-for-service and Medicare health maintenance organization (HMO) patients as well as non-Medicare patients ages 65-75 who were covered by private fee-for-service and private HMO plans.

Having a strong relationship with a personal physician can improve patient health outcomes. Yet achieving and sustaining this type of patient-physician relationship is often not possible in the current American health care system. Pisacano scholars and alumni, a group of young physician leaders supported by the American Board of Family Medicine, gathered for a 2-day symposium in June 2010 to explore the meaning of personal doctoring and its importance to our work as family physicians.

Evidence supports the effectiveness of primary care interventions to improve nutrition, increase physical activity levels, reduce alcohol intake, and stop tobacco use. However, implementing these interventions requires considerable practice expense. If we hope to change behavior to reduce chronic illness, the way we pay for primary care services must be modified to incorporate these expenses.
