Beyond Functional Outcomes: Exploring Quality of Life After Critical Illness-A Qualitative Study.

Abstract

Objectives: After ICU admission, the quality of life (QoL) of ICU survivors is often significantly lower compared to their peers. However, recent studies showed that this impaired QoL cannot be fully explained by the physical, mental, and cognitive problems post-ICU, alluding to other determinants of QoL. Therefore, we aimed to explore ICU survivors' experienced QoL 1-2 years post-ICU, focusing on factors beyond functional outcomes.

Design: Qualitative interview study.

Setting: Seven hospitals in the Netherlands.

Patients: ICU survivors aged greater than or equal to 16 years admitted to the ICU between July 2022 and January 2023.

Interventions: None.

Measurements and main results: ICU patients were purposively sampled. Interviews were audiotaped, transcribed, and analyzed according to the principles of thematic content analysis. All interviews were coded independently by two researchers and participant recruitment was continued until no new themes were identified. Twenty-four semistructured interviews were performed between March and June 2024. The interviews resulted in 28 categories, from which seven main themes emerged regarding patients' experienced QoL: functional impairments (e.g., physical problems), participation (e.g., independence, work), support (e.g., informal care), environment (e.g., financial resources, personal circumstances), individual values (e.g., perspective on life, religion), comparison (e.g., expectations, reference), and coping (e.g., adaptation, acceptance). Patients described how these themes affected their QoL, both positively and negatively.

Conclusions: This study shows that perceived QoL after critical illness is impacted not only by patients' functional impairments but also by participation, support, environment, individual values, comparison, and coping. The themes identified in this study stress the importance of considering patients' individual and context factors to provide optimal post-ICU support.
