recommendations and alerting for delirium alleviation in real-time (radar)

Conditions: Delirium

Summary: this is a pilot randomized controlled trial that will test whether a multicomponent decision support system will improve the postoperative environment for neurocognitive and clinical recovery in older, high-risk surgical patients. decision support systems will be tested that provide targeted alerts and recommendations to the hospital elder life program and family members for delirium prevention.

delirium is a distressing and common surgical complication, affecting approximately 20-50% of older surgical patients. postoperative delirium is associated with increased mortality, cognitive and functional decline, and healthcare resource utilization. prevention programs have been tested with variable success, but the hospital elder life program (help) has consistently been demonstrated to reduce the incidence and impact of delirium. however, substantial resources are needed for program operations, and complementary support systems may help with patient triage and assessment. family members and caretakers may be able to provide supplementary support with delirium screening and prevention via targeted, therapeutic activities. thus, an automated postoperative paging system, which elicits additional, focused support from help and family members, may augment delirium prevention activities and reduce associated risk. the primary objectives of this study are to determine whether pager-based clinical decision support systems bolster help- and family-based therapeutic activities. a secondary objective will be to identify facilitators and barriers to delivering therapeutic interventions for both help and family members. overall, this pilot trial will test the hypothesis that a multicomponent decision support system will improve the postoperative environment for neurocognitive and clinical recovery in older, high-risk surgical patients. patients (n=60) will be randomized to one of four groups in a factorial design: usual care (n=15), help-based paging system (n=15), family-based paging system (n=15), or both help- and family-based paging system (n=15). the support systems will consist of automated pager alerts to the help program and/or family members and caretakers, depending on group allocation, for providing additional delirium evaluation and therapeutic prevention activities. outcomes will include various clinical, neurocognitive, and functional measures, and performance metrics will be collected regarding help- and family-based interventions.
