Research assessing the delivery of preventive health care has considerable potential for improving health outcomes and reducing health care costs for the United States population.
To characterize the prevention health care delivery research grant portfolio supported by the National Institutes of Health (NIH).
Materials and Methods:
A random sample of 14,523 NIH research projects funded during 2012–2019 was selected and coded for various study topics using a structured taxonomy. We analyzed the subset of prevention research projects, for which health care delivery was identified as an independent or dependent variable, including study characteristics and funding trends.
Overall, 11.2% of NIH-funded prevention research projects were relevant to health care delivery. Of these projects, 68.6% assessed access to care, 53.4% examined quality, and 27.1% assessed costs. Over the study period, the percentage of funded prevention research projects involving health care delivery increased from 10.9%–15.1%. Over half of the projects assessed research related to the prevention of a new health condition, identification of risk factors, or health promotion (55.5%), whereas < half addressed prevention of disease progression/recurrence (40.4%), screening for early disease (20.2%), or screening for risk factors (1.4%). human immunodeficiency virus/acquired immune deficiency syndrome, cancer, and substance use were the most prevalent health topics studied, whereas other topics—such as lung diseases and Alzheimer disease—were less frequently studied.
Health care delivery research comprises a modest portion of the NIH prevention research portfolio and is mostly focused on access and quality of care; cost-related analyses are less prevalent.
human immunodeficiency virus/acquired immune deficiency syndrome, cancer, and substance use are frequently studied health topics in this portfolio.
