Abstract

Objective To investigate differences in healthcare cost trends over 8 years in adults with diabetes and one of four categories of comorbid depression: no depression, unrecognized depression, asymptomatic depression, or symptomatic depression.Research design and methods Data from the 2004-2011 Medical Expenditure Panel Survey (MEPS) was used to create nationally representative estimates. The dependent variable was total healthcare expenditures for the calendar year, including office-based, hospital outpatient, emergency room, inpatient hospital, prescription, dental, and home health care expenditures. The 2004-2011 direct medical costs were adjusted to a common 2014 dollar value. The primary independent variable was four mutually exclusive depression categories created from ICD-9-CM codes and the PHQ-2 depression screening tool. Healthcare expenditures were estimated using a two-part model and were adjusted for age, sex, race, marital status, education, health insurance, metropolitan statistical area status, region, income level, and comorbidities.Results Based on a national sample of adults with diabetes (unweighted sample of 15,548, weighted sample of 17,465,579), 10.2 % had unrecognized depression, 13.6 % had asymptomatic depression, and 8.9 % had symptomatic depression. In the pooled sample, after adjusting for covariates, the incremental cost of unrecognized depression was $2872 (95 % CI 1660-4084), asymptomatic depression increased by $3347 (95 % CI 2568-4386), and symptomatic depression increased by $5170 (CI 95 % 3610-6731) compared to patients with no depression.Conclusions Adjusted analyses showed that expenditures were $2000-3000 higher for unrecognized and asymptomatic depression than no depression, and $5000 higher for symptomatic depression. Higher medical expenditures persisted over time, with only symptomatic depression showing a sustained decrease over time.

  • Comorbid MDD in people with type 2 diabetes is associated with increased health care costs.

    “Comorbid MDD in people with type 2 diabetes is associated with poorer adherence to diabetes treatment52 and self-care activities (e.g., exercise, healthy eating)53,54, increased health care costs22,54, reduced glycemic control55,56, and increased hospital admissions and complications57-60.”

    The Conclusions report higher medical expenditures among adults with diabetes and comorbid depression. However, the study does not isolate people with type 2 diabetes or establish that its depression categories represent diagnosed major depressive disorder (Depression section). (LLM, conf=0.88)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
