BackgroundNeoplasm-related pain is often suboptimally treated, contributing to avoidable suffering and increased medical resource use and costs. We hypothesized that dementia may contribute to increased resource use and costs in patients hospitalized for neoplasm-related pain in the United States.AimsTo examine how persons with cancer and dementia use medical resources and expenditures in US hospitals compared to ondividuals without dementia.DesignThis study examined a retrospective cohort.SettingAdmissions to US hospitals for neoplasm-related pain from 2012-2016 PARTICIPANTS/SUBJECTS: METHODS: Data were obtained from the 2012-2016 National Inpatient Sample (NIS). The sample included hospital admissions of individuals aged 60 or older with a primary diagnosis of neoplasm-related pain. Dementia was defined using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM), and ICD-10-CM diagnosis codes. Primary outcomes were number of admissions, costs, and length of stay (LOS). Descriptive statistics and multivariable regression models were used to examine the relationships among dementia, costs, and LOS.ResultsOf 12,034 admissions for neoplasm-related pain, 136 (1.1%) included a diagnosis of dementia and 11,898 (98.9%) did not. Constipation was present in 13.2% and 24.5% of dementia and nondementia admissions, respectively. The median LOS was 4 days in persons with dementia and three in those without. Mean costs per admission were higher in persons without dementia ($10,736 vs. $9,022, p = .0304). In adjusted regression results, increased costs were associated with nonelective admissions and longer LOS, and decreased costs with age above the mean. In contrast, decreased LOS was associated with age above the mean and nonelective admissions. Dementia was associated with neither endpoint.ConclusionThis study provides nurses and other health care professionals with data to further explore opportunities for improvement in cancer pain management in patients with and without dementia that may optimize use of medical resources.Copyright © 2021 Elsevier Ltd.
