Psychosocial impact of living with an indwelling pleural catheter in patients with malignant pleural effusions: a thematic analysis

Background Breathlessness is a frequent and debilitating symptom experienced by patients with malignant pleural effusions (MPEs). Indwelling pleural catheters (IPCs) are a recommended first line treatment option, but the psychological and social impact of living with one is poorly understood. Objectives To determine the psychosocial impact of living with an IPC among patients with MPEs. Methods 18 adult English-speaking patients undergoing IPC management for MPEs were recruited at a single pleural centre in London, UK, between May 2022 and 2023. 23 semi-structured interviews were conducted at 2 weeks and 6–8 weeks post IPC insertion. Inductive thematic analysis of the interview transcripts was used to identify key psychosocial impacts and modulatory factors. Results 13 participants completed the semi-structured interviews, mean age 67, 54% female. Seven themes relating to the psychosocial impacts experienced by individuals living with an IPC were identified: anxiety, activities, relationships, independence and control, expectations and adjustments to IPC, acceptance and confidence. These evolved over time, with both positive and negative effects. The effects of the psychosocial impacts were further mediated by three modulatory factors: IPC mediated changes, challenges of IPC care and the overarching impact of cancer. These exerted varying degrees of influence on individuals’ psychosocial wellbeing. Conclusions This qualitative study highlights for the first time the range of psychosocial impacts experienced by individuals living with an IPC. Identifying the modulatory factors and understanding how these impact patient experience can help to direct future interventions aiming to improve the psychosocial wellbeing for this population.
