Diagnosis isn't enough: Understanding the connections between high health care utilization, chronic conditions and disabilities among U.S. working age adults

Abstract

Background Under the ACA, new programs are being developed to enhance care coordination and reduce healthcare costs among people with chronic conditions, disabilities, and high utilization of healthcare. However, the relationships between these groups are not well understood. Objectives Our aims were to (1) identify high utilizers of healthcare in the U.S. working-age (18-64) population, (2) examine the overlap between this group and people with chronic conditions and/or disabilities, (3) identify predictors of high service use or cost among these subpopulations, and (4) recommend approaches for stratification of individuals with high healthcare utilization. Methods Using pooled national data from the Medical Expenditure Panel Survey (2006–2008), we created indices to identify elevated or high utilization and cost groups. We performed descriptive analyses, bivariate comparisons and multivariate analyses to examine the relations between these populations and individuals with chronic conditions and/or disabilities. Results While the large majority of persons with high use/cost had chronic conditions, the minority of persons with chronic conditions had high healthcare utilization. However, among persons with chronic conditions, disability was a significant predictor of high utilization. Annual expenditures were significantly elevated among people with disabilities, particularly when activities of daily living were limited. Conclusions We conclude that medical diagnosis alone is insufficient for the development of eligibility criteria for, or the evaluation of, programs intended to better the delivery or coordination of services for high utilizers of health care services. New approaches are needed to assess functional limitations and identify ongoing needs for services and supports.

Live birth, miscarriage, and abortion among U.S. women with and without disabilities

“…Secondary data sources rarely include information on environmental supports and barriers; therefore, disability is typically assessed through self-report of functional ability and participation restrictions when such data are available [e.g. 2, 21–27]. Research examining specific conditions associated with self-report of functional or participation limitations has found that common underlying conditions include arthritis, back problems, other musculoskeletal problems, pulmonary problems (e.g.…”

Introducing the Adults with Chronic Healthcare Needs (ACHCN) definition and screening instrument: Rationale, supporting evidence and testing

“…Using pooled secondary data from the 2006–2008 Medical Expenditure Panel Survey, we conducted detailed analyses of the relations between high healthcare utilization, functional limitations and chronic conditions. 42 In order to identify working age individuals with (and without) one or more chronic conditions, we used the HCUP chronic condition list (AHRQ) which specifies health and mental health conditions expected to last a year or more by ICD-9 code. We identified persons with limitations on the basis of the functional measures provided in MEPs.…”

Adults with Communication Disabilities Experience Poorer Health and Healthcare Outcomes Compared to Persons Without Communication Disabilities

“…Other disability types were included as a control measure because a substantive body of literature has shown a significant overlap between these disability types and poor health and healthcare outcomes. 15,16 Models including other disability types revealed few differences (details available upon request). We chose to present the models controlling for other disability types to more conservatively assess the impact of CD on outcomes.…”
