Background Postintensive care syndrome (PICS) has been identified in a large proportion of medical intensive care unit survivors; however, the occurrence surgical intensive care unit (SICU) survivors is unknown. We implemented a multidisciplinary critical care outpatient clinic (CCOC) to identify the occurrence of PICS in SICU survivors. Methods Seventy acute care surgery and trauma patients, 18 years or older, who remained in the SICU for 72 hours or longer at a Level I trauma center were seen in CCOC at 2 weeks, 12 weeks, and 24 weeks after hospital discharge. The CCOC staffing included a nurse coordinator, social worker, critical care pharmacist, physical therapist, and acute care surgeon who identified PICS sequelae in their respective specialties by clinical criteria and screening questionnaires. Results Of 82 eligible patients, 70 (85.4%) were seen at least once for 116 total visits. Forty-three (61.4%) patients suffered traumatic injuries and 27 (38.6%) underwent emergent general surgery. Sixty-seven (95.7%) demonstrated at least one PICS criterion. Over all visits, 26 (37.1%) patients presented with one PICS criterion, 24 (34.3%) patients with two, and 17 (24.3%) with three. Cognitive impairment was observed in 29 (41.4%) patients, psychiatric in 30 (42.9%), and physical symptoms in 65 (92.9%). Activity Measure for Post-Acute Care scores improved from severe impairment at admission to full function by 12 weeks postdischarge, yet 6 Minute Walk Test scores remained below age-matched references through all visits. Patients expressed mild to moderate depression based on Patient Health Questionnaire-9 scores. A medication reconciliation was completed at 96.5% (112/116) of the visits with 116 total medication recommendations. By 24 weeks following discharge, only 26.4% (14/53) of previously employed patients had resumed work. Conclusion Through the successful implementation of a multidisciplinary CCOC, this study identifies an exorbitant rate of PICS among SICU survivors. Level of evidence Therapeutic/epidemiological, level III.
