Abstract

Background: We evaluated whether the DELirium Team Approach (DELTA) program—a systematic management program aimed at screening high-risk groups and preventing delirium—would improve quality of care in patients hospitalized with cancer. Methods: A retrospective before–after study was conducted during a pre-intervention period (between October 2012 and March 2013) and a post-intervention period (between October 2013 and March 2014) at a Japanese hospital providing specialized treatments for cancer. A total of 4180 inpatients were evaluated before the implementation of the DELTA program and 3797 inpatients were evaluated after implementation. Results: After program implementation, the incidence of delirium decreased from 7.1 to 4.3% (odds ratio [OR], 0.52; 95% CI, 0.42–0.64). The incidence of adverse events, including falls or self-extubation, also decreased, from 3.5 to 2.6% (OR, 0.71; 95% CI, 0.54–0.92). There was a significant decrease in the prescription of benzodiazepines (OR, 0.79; 95% CI, 0.71–0.87), increase in the level of independence in activities of daily living at discharge (OR, 1.94; 95% CI, 1.11–3.38), and decrease in the length of stay (risk ratio 0.90; 95% CI, 0.90–0.90). Conclusions: The systematic management program for delirium decreased the incidence of delirium and improved several clinical outcomes. These data suggest that this simple cost-effective program is feasible and implementable as routine care in busy wards.
