Abstract
Purpose
The aim of this study was to investigate the predictive value of a clinical tool to predict whether discharged cancer patients die at home, comparing groups of case who died at home and control who died in hospitals or other facilities.
Method
We conducted a nationwide case-control study to identify the determinants of home death for a discharged cancer patient. We randomly selected nurses in charge of 2000 home-visit nursing agencies from all 5813 agencies in Japan by referring to the nationwide databases in January 2013. The nurses were asked to report variables of their patients’ place of death, patients’ and caregivers’ clinical statuses, and their preferences for home death. We used logistic regression analysis and developed a clinical tool to accurately predict it and investigated their predictive values.
Results
We identified 466 case and 478 control patients. Five predictive variables of home death were obtained: patients’ and caregivers’ preferences for home death [OR (95% CI) 2.66 (1.99–3.55)], availability of visiting physicians [2.13 (1.67–2.70)], 24-h contact between physicians and nurses [1.68 (1.30–2.18)], caregivers’ experiences of deathwatch at home [1.41 (1.13–1.75)], and patients’ insights as to their own prognosis [1.23 (1.02–1.50)]. We calculated the scores predicting home death for each variable (range 6–28). When using a cutoff point of 16, home death was predicted with a sensitivity of 0.72 and a specificity of 0.81 with the Harrell’s c-statistic of 0.84.
Conclusion
This simple clinical tool for healthcare professionals can help predict whether a discharged patient is likely to die at home.
