      Abstract

      Background

      Patients transferred from the respiratory intensive care unit (ICU) can experience post–intensive care syndrome (PICS), which comprises cognitive, psychological, and physical disorders that seriously affect the quality of life. Therefore, it was necessary to explore the incidence of and the risk factors for PICS among respiratory ICU patients.

      Objectives

      This study evaluated PICS among respiratory ICU patients and explored the risk factors for PICS.

      Methods

      This cross-sectional, prospective study was performed at one hospital in China. Using convenience sampling, 125 respiratory ICU patients from August 2018 to June 2019 were recruited for the study. The Mini-Mental State Examination, Confusion Assessment Method for the Intensive Care Unit, Hospital Anxiety and Depression Scale, Medical Research Council Scale, activities of daily living scale, Pittsburgh Sleep Quality Index, and the 14-item fatigue scale were used to comprehensively assess the patients' cognitive status, psychological status, and physiological status when entering the ICU and 2 weeks after leaving the ICU. Factors affecting PICS were measured using researcher-created questionnaires of patients’ general information and disease-related information.

      Results

      Fifteen patients were lost to follow-up. Fifty-nine patients had PICS (incidence rate, 53.6%). Logistic regression showed that risk factors for PICS were age, invasive mechanical ventilation, noninvasive ventilator-assisted ventilation, and coronary heart disease (P < 0.05).

      Conclusion

      The PICS incidence was high. Older age, longer invasive mechanical ventilation times, longer noninvasive ventilator times, and coronary heart disease were risk factors for PICS. ICU medical workers in China should pay more attention on PICS, know the risk factors, and implement preventive measures.
