HALT (Hernia Active Living Trial): protocol for a feasibility study of a randomised controlled trial of a physical activity intervention to improve quality of life in people with bowel stoma with a bulge/parastomal hernia

Hernia Active Living Trial (HALT): a feasibility study of a physical activity intervention for people with a bowel stoma who have a parastomal hernia/bulge

BACKGROUND

Parastomal bulging/hernia is a common complication associated with a stoma. Strengthening of the abdominal muscles via exercise may be a useful self-management strategy. The aim of this feasibility work was to address uncertainties around testing a Pilates-based exercise intervention for people with parastomal bulging.

METHODS

An exercise intervention was developed and tested in a single-arm trial (n = 17 recruited via social media) followed by a feasibility randomised controlled trial RCT (n = 19 recruited from hospitals). Adults with an ileostomy or colostomy with a bulge or diagnosed hernia around their stoma were eligible. The intervention involved a booklet, videos, and up to 12 online sessions with an exercise specialist. Feasibility outcomes included intervention acceptability, fidelity, adherence, and retention. Acceptability of self-report measures for quality of life, self-efficacy, and physical activity were assessed based on missing data within surveys pre- and post-intervention. Interviews (n = 12) explored participants' qualitative experiences of the intervention.

RESULTS

Nineteen of 28 participants referred to the intervention completed the programme (67%) and received an average of 8 sessions, lasting a mean of 48 min. Sixteen participants completed follow-up measures (44% retention), with low levels of missing data across the different measures, apart from body image and work/social function quality of life subscales (50% and 56% missing, respectively). Themes from qualitative interviews related to the benefits of being involved, including behavioural and physical changes in addition to improved mental health. Identified barriers included time constraints and health issues.

CONCLUSIONS

The exercise intervention was feasible to deliver, acceptable to participants, and potentially helpful. Qualitative data suggests physical and psycholosical benefits. Strategies to improve retention need to be included in a future study.

Quality of life profiles and their association with clinical and demographic characteristics and physical activity in people with a stoma: a latent profile analysis

Purpose

Quality of life can be negatively impacted by the formation of a stoma and is influenced by a number of factors. Research to date treats people with a stoma as a homogenous group based on their quality of life. We attempted to identify subgroups based upon self-reported quality of life and explored variables associated with group membership.

Methods

The present study is a secondary analysis of a cross-sectional sample of 1419 people with a stoma. Participants completed validated questionnaires for quality of life, physical activity and clinical and demographic characteristics. Latent profile analysis was used to identify the optimal number of subgroups (profiles) and multinomial regression modelling was conducted to identify variables associated with profile membership.

Results

The analysis revealed 4 distinct profiles of people with a stoma: ‘consistently good quality of life’ [N = 891 (62.8%)], ‘some quality of life concerns’ [N = 184 (13.0%)], ‘low quality of life’ [N = 181 (12.8%)] and ‘financial concerns’ [N = 163 (11.5%)]. Modelling revealed that people with a recent stoma (formed < 2 years previously), who have a hernia and are less physically active were more likely to belong to the ‘low quality of life’ profile. Furthermore, those aged 16–55 were more likely to have financial concerns.

Conclusion

This study was the first to identify latent profiles within this population and assess whether certain variables are associated with membership. Future research should build upon this to identify additional variables associated with these profiles, which can help to provide the basis for targeting and tailoring future interventions to specific subgroups of people with a stoma.
