IntroductionThe Health Effectiveness Data and Information Set (HEDIS) measures are indicators used by more than 90% of national health plans to assess quality of care on important health issues (National Committee for Quality Assurance [NCQA], 2016)). This article will focus on the HEDIS measurement of physical activity in older adults. This document will affirm the importance of physical activity in the national health landscape and analyze the guidelines and research that influence this measure. Finally, the significance and effectiveness of this measure in primary care will be discussed. Background With the development of the HEDIS measures, the emphasis on physical activity in older adults has taken on greater importance. Physical inactivity contributes approximately 27% to national healthcare costs, and older adults are more likely to develop chronic diseases preventable with physical activity (Neidrick, Fick, & Loeb, 2012). Currently, fewer than 20% of older adults meet CDC activity recommendations, and more than half are believed to lead a sedentary lifestyle (National Quality Measures Clearinghouse [NQMC], 2015; Neidrick, Fick, & Loeb, 2012). Specifically, physical inactivity increases the risk of obesity, cardiovascular disease, hypertension, stroke, type 2 diabetes, and cancer (Centers for Disease Control [CDC], 2015). Additionally, less active older adults are at greater risk for musculoskeletal disorders such as arthritis and osteoporosis, and muscle weakness and imbalance can contribute to falls and injuries (CDC, 2015). 93% of elderly people turn to their GP. (PCP) each year, providing a unique opportunity for providers to target this population and encourage and improve quality of life in older adults (USDHHS, 1996). While the measurement can determine the percentage of patients who have had discussions with providers about physical activity, the correlation between counseling and increased long-term physical activity in older adults has not been demonstrated through research (NQMC, 2015 ; Neidrick, Fick, & Loeb, 2012). . Future research should focus on the effectiveness of the HEDIS measure in producing positive outcomes, as well as what specific interventions increase the effectiveness of increasing long-term physical activity in older adults. The benefits of physical activity for older patients – reducing costs, improving chronic health conditions, preventing disease, and improving quality of life – are substantial, and providers must continue to find ways to include this important discussion in health measures preventive when possible.
