Co-design and feasibility testing of the heart failure carer support programme (HELP): A convergent, mixed-method study

Objectives This study co-designed and feasibility tested a novel psychoeducational intervention delivered online to carers of patients with heart failure (HF) and examined the potential impact on carer-related outcomes. Methods The HEart faiLure carer support Programme (HELP) was co-designed with carers and healthcare professionals at a large University hospital. This intervention comprises an information booklet and six psychoeducational support group sessions delivered online by a multidisciplinary team. A convergent mixed-method design examined the feasibility, acceptability, and potential impact of HELP. Carers of patients with HF were recruited in the United Kingdom (UK) via clinical teams along with printed and online advertisements. Quantitative measurements included carer-related outcomes (carer burden, carer preparedness, quality of life, anxiety, depression, stress, and social support) and feasibility assessments (recruitment rates, attrition, and intervention usefulness). Focus groups conducted post-intervention qualitatively investigated the acceptability of HELP. Data was collected at baseline, 6 weeks post-intervention, and 3 months post-intervention. Quantitative and qualitative data were analyzed with descriptive and thematic analysis, respectively. The results were integrated to generate a holistic understanding of the findings. Results 51 carers were eligible and 22 (43 %) provided consent. Of those 22, 18 (89 %) participated and 12 (67 %) completed all intervention sessions. Participants highly rated the usefulness of the intervention via a feedback questionnaire (4.7 ± 0.59 out of 5, overall) and positive changes were found across the following carer-related outcomes: anxiety, depression, caregiver burden, stress, preparedness, and social support. Data integration generated three key findings: (1) Improved carer preparedness and knowledge, (2) Support from group environment, and (3) Emotional support and personal wellbeing. Conclusions HELP delivery to carers of patients with HF is feasible and potentially provides emotional support and empowerment in their caring role. Practice implications HELP will advance to implementation testing across the UK to inform large-scale adoption in routine clinical practice.
