Clinical question: Is continuity of care related to preventable hospitalizations among older adults?
Background: Preventable hospitalizations cost approximately $25 billion annually in the U.S. The relationship between continuity of care and the risk of preventable hospitalization is unknown.
Study design: Retrospective cohort study.
Setting: Random sample of fee-for-service Medicare beneficiaries, for ambulatory visits and hospital admissions.
Synopsis: This study examined 3.2 million Medicare beneficiaries using 2008-2010 claims data to measure continuity and the first preventable hospitalization. The Prevention Quality Indicators definitions and technical specifications from the Agency for Healthcare Research and Quality were used to identify preventable hospitalizations. Both the continuity of care score and usual provider continuity score were used to calculate continuity metrics. Baseline risk of preventable hospitalization included age, sex, race, Medicaid dual-eligible status, and residential zip code.
During a two-year period, 12.6% of patients had a preventable hospitalization. After adjusting for variables, a 0.1 increase in continuity of care was associated with about a 2% lower rate of preventable hospitalization. Interestingly, continuity of care was not related to mortality rates.
This study extends prior research associating continuity of care with reduced rate of hospitalization; however, the associations found cannot assert a causal relationship. This study used coding practices that vary throughout the country, included only older fee-for-service Medicare beneficiaries, and could not verify why some patients had higher continuity of care. The authors suggest that efforts to strengthen physician-patient relationships through high-quality primary care will deter some hospital admissions.
Bottom line: Higher continuity of ambulatory care is associated with lower preventable hospitalizations in Medicare beneficiaries.
