Abstract
Aim: In this study we aimed to assess the responsiveness of the symptom score of the recently developed Patient-Reported Outcome Measure-Haemorrhoidal Impact and Satisfaction Score (PROM-HISS). Furthermore, the minimally relevant difference (MRD) was determined. Method: The responsiveness of PROM-HISS was tested using a criterion-based (i.e. anchor) and construct-based (i.e. hypotheses testing) approach. Patients with haemorrhoidal disease (HD) completed the PROM-HISS before and 1 week after treatment in hospital. A global self-assessment of change question (SCQ) was administered 1-week after treatment and functioned as the criterion. The following analyses were performed: (1) correlation between the PROM-HISS symptom score and the criterion (SCQ) and (2) hypotheses testing. The MRD was determined as change in symptoms of the subgroup reporting ‘somewhat fewer complaints’ on the SCQ. Results: Between February and August 2022, 94 patients with grade II–IV HD from three hospitals were included. The correlation between the SCQ and a change on the PROM-HISS symptom score was 0.595 indicating that an improvement on the SCQ corresponds to an improvement on the PROM-HISS symptom score. As hypothesized, the mean change in PROM-HISS scores was significantly different between subgroups of patients based on their SCQ responses. Patients reporting a small change in HD symptoms on the SCQ corresponded to a mean change of 0.3 on the PROM-HISS symptom score. Conclusion: The PROM-HISS symptom score is a responsive instrument as it identifies change in HD symptoms because of treatment. The estimated MRD of 0.3 can be used to inform clinical research and practice.
