ABSTRACTImportanceGeneral health checks—also known as general medical exams, periodic health evaluations, checkups, or wellness visits—to identify and prevent disease are extremely common in adult primary care. Although general health checks are often expected and advocated by patients, clinicians, payers, and health systems, others question their value. The current evidence was updated and recommendations provided for conducting general health checks in adults.ObservationsRandomized trials and observational studies with control groups from prior systematic reviews and an updated literature review through December 2020 were included. Out of 19 included randomized trials (906 to 59,616 participants; follow-up, 1 to 30 years), 5 evaluated a single general health check and 7 evaluated annual health checks. All of 12 included observational studies (240 to 471,415 participants; follow-up, cross-sectional to 5 years) evaluated a single general health check. General health checks were generally not associated with decreased mortality, cardiovascular events, or cardiovascular disease incidence. For example, in the South-East London Screening Study (n=7,229), adults age 40 to 64 who were invited to two health checks over two years experienced no 8-year mortality benefit (6% overall). However, general health checks were associated with increased detection of chronic diseases, such as depression and hypertension; moderate improvements in controlling risk factors such as blood pressure and cholesterol; increased clinical preventive service uptake, such as colorectal and cervical cancer screening; and improvements in patient-reported outcomes, such as quality of life and self-rated health. General health checks were sometimes associated with modest improvements in health behaviors such as physical activity and diet. For example, in the OXCHECK trial (n=4121), fewer intervention participants exercised less than once per month (68% versus 71%). Potential adverse effects in individual studies included an increased risk of stroke and increased mortality attributed to increased completion of advanced directives.Conclusions and RelevanceGeneral health checks were not associated with reduced mortality or cardiovascular events, but were associated with increased chronic disease recognition and treatment; risk factor control, preventive service uptake, and patient-reported outcomes. Primary care teams may reasonably offer general health checks, especially for groups at high risk of overdue preventive services, uncontrolled risk factors, low self-rated health, or poor connection to primary care.
