Integrating into primary care for with chronic, life-limiting conditions 2.0 CONTACT HOURS Integrating palliative care into primary care for patients with chronic, life-limiting conditions

Abstract: As longevity increases, individuals with chronic, life-limiting conditions will live longer with disease burden and functional decline. Nurse practitioners can integrate symptom management, early decision-making, and supportive care into the primary care setting to improve quality of life and decrease economic and emotional impact at the end of life.

By Ann Selena Cleary, DNS, RN, NP-C

lthough life expectancy is increasing worldwide, living longer is not always syn- onymous with a greater number of healthy years, as increasing age and risk for A developing a chronic, life-limiting condition are related. Approximately 20 mil- lion older individuals in the have at least two or more chronic, life-limiting conditions; the most common are mellitus, , high cholesterol, and heart disease.1 These conditions last more than 1 year, require ongoing medical care, and affect inde- pendence and activities of daily living.2 Increased ED and offi ce visits, hospitalizations, and home healthcare services are associated with increasing age and multiple chronic conditions. In 2010, more than half of Medicare expenditure went to hospitalizations for 15% of the Medicare population, a disproportionate amount.3 In essence, this population is likely to experience increasing symptoms and a decrease in quality of life for several years prior to death. The majority of older adults in the United States have under Medicare, which includes a benefi t for the last 6 months of life. However, patients could live months to years with increasing symptoms and worsening quality of life prior to hospice eligibility. During this time, care goals should
