Performance of the Healthy Aging Brain Care Monitor Self Report in Monitoring Post-Intensive Care Syndrome Among Acute Respiratory Failure Survivors

Abstract

Objectives: To describe the performance of the Healthy Aging Brain Care Monitor Self Report (HABC-M SR) in assessment of post-intensive care syndrome (PICS) among Acute Respiratory Failure ICU survivors.

Design: Secondary data analysis of a randomized controlled trial.

Setting: Patients evaluated by a nurse care coordinator in an out-of-hospital setting.

Patients: English-speaking adults 18 years old or older who were admitted to the ICU with acute respiratory failure requiring invasive or noninvasive mechanical ventilation for greater than or equal to 24 hours.

Interventions: Patients randomized to the intervention arm of the mobile critical care recovery program, a negative trial testing multidisciplinary care to improve quality of life.

Measurements and main results: HABC-M SR scale was used to assess PICS in the intervention group at ICU discharge, 3, and 6 months post-discharge. Hospital Anxiety and Depression Scale; Pain, Enjoyment of Life, and General Activity Scale; Timed Up and Go; and Patient-Reported Outcomes Measurement Information System sleep scores were obtained at the same time. Mini-Mental State Examination (MMSE) was administered at baseline and 6 months. ICU survivors reported mild PICS symptoms, which improved over 6 months (mean HABC-M SR scores: baseline [8.5, sd 7.6], 3 mo [5.3 mo, sd 6.6 mo], and 6 mo [5.2 mo, sd 6.9 mo; p < 0.001]). HABC-M SR total score had moderate internal consistency that improved over time (Cronbach's alpha = 0.78 at baseline and 0.84 at 6 mo). The psychological subscale of HABC-M SR was moderately correlated with standardized scales for mood, pain, and sleep. The cognitive subscale was not significantly correlated with MMSE.

Conclusions: While HABC-M SR correlated with mood, physical, and sleep symptoms, the cognitive subscale was less sensitive compared with standardized scales.
