Multimorbidity, not human immunodeficiency virus (HIV) markers predicts unplanned admission among people with HIV in regional New South Wales

摘要

Abstract Background Multimorbidity and unplanned admissions are common among people with human immunodeficiency virus (PWH). Aims To determine factors predictive of unplanned admission among PWH in regional New South Wales and compare care coordination between people with and without unplanned admissions. Methods A prospective cohort study of PWH attending a regional human immunodeficiency virus (HIV) service was conducted. Baseline HIV‐specific results and multimorbidity markers including Cumulative Illness Rating Scale (CIRS) were assessed as predictors of time to first unplanned admission using Cox regression analysis. Care coordination markers were compared between people with and without unplanned admission, using χ 2 statistic for proportions and t ‐test for means. Results A cohort of 181 PWH was followed for a maximum of 5 years. During a total of 739 person‐years of follow up, 39 (20.6%) patients reached the endpoint of unplanned admission. In multivariate analysis, the baseline CIRS score was predictive of unplanned admission ( P 0.001). Age, HIV‐specific markers and missed visits were not predictive of unplanned admission. For patients with an unplanned admission, discharge summaries were documented for 22/39 (56.4%). Of 180 PWH with a visit after baseline, 131 (72.8%) had a letter to a general practitioner and 79 (43.7%) had two or more prescribers. Having two or more prescribers was more common in people with an unplanned admission than in those without (64.1% vs 38.0%, P = 0.004). Conclusion Unplanned admission among PWH is predicted by multimorbidity. Care for PWH should include coordinated management of other health conditions in order to reduce their severity and prevent unplanned admissions.
