Pain, agitation and delirium assessment and management in a community medical-surgical ICU: results from a prospective observational study and nurse survey

BACKGROUND: Delirium is a common manifestation in the intensive care unit (ICU) that is associated with increased mortality and morbidity. Guidelines suggested appropriate management of pain, agitation and delirium (PAD) is crucial in improving patient outcomes. However, the practice of PAD assessment and management in community hospitals is unclear and the mechanisms contributing to the potential care gap are unknown. OBJECTIVES: This quality improvement initiative aimed to review the practice of PAD assessment and management in a community medical-surgical ICU (MSICU) and to explore the community MSICU nurses’ perceived comfort and satisfaction with PAD management in order to understand the mechanisms of the observed care gap and to inform subsequent quality improvement interventions. METHODS: We prospectively collected basic demographic data, clinical information and daily data on PAD process measures including PAD assessment and target Richmond Agitation-Sedation Scale (RASS) score ordered by intensivists on all patients admitted to a community MSICU for >24 hours over a 20-week period. All ICU nurses in the same community MSICU were invited to participate in an anonymous survey. RESULTS: We collected data on a total of 1101 patient-days (PD). 653 PD (59%), 861 PD (78%) and 439 PD (39%) had PAD assessment performed, respectively. Target RASS was ordered by the intensivists on 515 PD (47%). Our nurse survey revealed that 88%, 85% and 41% of nurses were comfortable with PAD assessment, respectively. CONCLUSIONS: Delirium assessment was not routinely performed. This is partly explained by the discomfort nurses felt towards conducting delirium assessment. Our results suggested that improvement in nurse comfort with delirium assessment and management is needed in the community MSICU setting.
