Abstract

Preventable hospital readmissions have been recognized as indicators of hospital quality, a source of increased healthcare expenditures, and a burden for patients, families, and caregivers. Despite growth of initiatives targeting risk factors associated with potentially avoidable hospital readmissions, the impact of dementia on the likelihood of rehospitalization is poorly characterized. Therefore, the primary objective of this retrospective cohort study was to investigate whether dementia was an independent predictor of 30-day readmissions. Administrative claims data for all admissions to Rhode Island hospitals in 2009 was utilized to identify hospitalizations of Medicare fee-for-service beneficiaries with a diagnosis of Alzheimer's Disease or other dementias. Demographics, measures of comorbid disease burden, and other potential confounders were extracted from the data and the odds of 30-day readmission to any United States hospital was calculated from conditional logistic regression models. From a sample of 25,839 hospitalizations, there were 3908 index admissions of Medicare beneficiaries who fulfilled the study criteria for a dementia diagnosis. Nearly 20% of admissions (n=5133) were followed by a readmission within thirty days. Hospitalizations of beneficiaries with a dementia diagnosis were more likely to be followed by a readmission within thirty days (adjusted odds ratio (AOR) 1.18; 95% CI, 1.08, 1.29), compared to hospitalizations of those of without dementia. Controlling for discharge site of care did not attenuate the association (AOR 1.21; 95% CI, 1.10, 1.33).

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.
