Abstract TP147: Factors Influencing Home Discharge Preference of Inpatients With Acute Cerebral Infarction: A Retrospective Cohort Study

Abstract

Background and Purpose: Many previous studies explained clinical predictors of discharge planning for inpatients with acute cerebral infarction, while the factors that influence inpatients and their family’s preference for discharge destination are not often investigated. The purpose of this study was to clarify the relationship between home discharge preference of inpatients with acute cerebral infarction and socio-demographic factors or clinical characteristics. Methods: We surveyed the electronic medical records of 2,495 (mean age 73.5+ years, 62% were male) acute cerebral infarction patients who were admitted to a stroke center in Japan between January 1, 2011 and December 31, 2015. The main outcome variable was the home discharge preference within 5 days after hospitalization. The explanatory variables were socio-demographic and clinical factors. Multiple logistic regression analysis with backward variable selection was performed to investigate relationships between home discharge preference and these factors. Results: In all, 1,056 (42%) patients showed their preference for discharge to their homes. Multiple logistic regression analysis identified relationships between discharge preference to home and five variables. Patients exhibiting the following characteristics tend to show the preference for discharge to their home: higher age, paresis, cancer, cohabitating, and higher functional independence measure motor (FIM-M) score on admission (13-91 points). The odds ratio of these factors for home discharge preference were 1.02 per a year (95% confidence interval[95%CI] 1.00-1.03), 3.68 (vs. without paresis, 95%CI 1.83-7.38), 2.35 (vs without cancer, 95%CI 1.11-4.94), 3.04 (vs. living alone, 95%CI 2.03-4.56), 1.06 (vs lower FIM-M score, 95% 1.05-1.07), respectively. The model showed an area under the curve equal to 0.83 (95%CI 0.80-0.86). Conclusion: Patients’ preference for home discharge is influenced largely by physical impairments and support availability. Additionally, patients with comorbidity such as cancer tend to choose facility care rather than home care. These results showed that development of a family support system for elder patients in multimorbid situations facilitated their decision for home discharge.
