Assessment of health-related quality of life and its determinants among COVID-19 intensive care unit survivors

Health-related quality of life (HRQoL) is a multidimensional concept encompassing the physical, functional, emotional, and social/family well-being of an individual. Recent reports suggest that Covid-19 may lead to poorer HRQoL of the patients infected both in the short and long term. The present study aimed to assess the health-related quality of life and their determinants among COVID-19 intensive care unit (ICU) survivors. In the study, 107 COVID-19 (RTPCR positive) patients admitted to the (ICU) of a tertiary care centre from August 2021-January 2022 were taken from the hospital records. Line listing of all the patients was done, and the study population was selected using the lottery method under a simple random sampling method. The study population was contacted by telephone and requested their willingness to participate in the study. EQ-5D-5L was used to assess quality of life, which is a standard instrument to assess HRQoL (developed by the EuroQol group in 2011). The EQ-5D-5L essentially consists of the EQ-5D descriptive system and the EQ visual analogue scale (EQ-VAS). Data entry was done using Microsoft excel 2019 version and data analysis using MedCalc version 20.015. The mean EQ-5D-5L utility score was 0.51 ± 0.43. The mean EQ-VAS score was 68.97 ± 22.27. A significant association between co-morbidities and EQ-5D-5L utility score where those with co-morbidities had a lesser EQ-5D-5L score compared to those without co-morbidities. The mean duration of ICU stay in days was 12.29 ± 12.17. A significant negative correlation between the duration of ICU stay and EQ-5D-5L. (r = -0.26, = 0.0006*). COVID-19 patients with comorbidities had a significantly poor quality of life. These findings may help healthcare professionals and decision-makers to better understand the consequences of COVID-19 on the HRQoL.
