Evaluation of Time-Limited Trials Among Critically Ill Patients With Advanced Medical Illnesses and Reduction of Nonbeneficial ICU Treatments.

ImportanceFor critically ill patients with advanced medical illnesses and poor prognoses, overuse of invasive intensive care unit (ICU) treatments may prolong suffering without benefit.ObjectiveTo examine whether use of time-limited trials (TLTs) as the default care-planning approach for critically ill patients with advanced medical illnesses was associated with decreased duration and intensity of nonbeneficial ICU care.Design, setting, and participantsThis prospective quality improvement study was conducted from June 1, 2017, to December 31, 2019, at the medical ICUs of 3 academic public hospitals in California. Patients at risk for nonbeneficial ICU treatments due to advanced medical illnesses were identified using categories from the Society of Critical Care Medicine guidelines for admission and triage.InterventionsClinicians were trained to use TLTs as the default communication and care-planning approach in meetings with family and surrogate decision makers.Main outcomes and measuresQuality of family meetings (process measure) and ICU length of stay (clinical outcome measure).ResultsA total of 209 patients were included (mean [SD] age, 63.6 [16.3] years; 127 men [60.8%]; 101 Hispanic patients [48.3%]), with 113 patients (54.1%) in the preintervention period and 96 patients (45.9%) in the postintervention period. Formal family meetings increased from 68 of 113 (60.2%) to 92 of 96 (95.8%) patients between the preintervention and postintervention periods (P < .01). Key components of family meetings, such as discussions of risks and benefits of ICU treatments (preintervention, 15 [34.9%] vs postintervention, 56 [94.9%]; P < .01), eliciting values and preferences of patients (20 [46.5%] vs 58 [98.3%]; P < .01), and identifying clinical markers of improvement (9 [20.9%] vs 52 [88.1%]; P < .01), were discussed more frequently after intervention. Median ICU length of stay was significantly reduced between preintervention and postintervention periods (8.7 [in
