Patient preferences for pilonidal sinus treatments: A discrete choice experiment survey

Abstract

AbstractAimA range of treatments are available for pilonidal sinus disease (PSD), each of which has a different risk/benefit profile. The aim of this study was to collect patient views on which interventions they would rather avoid and which outcomes they most value for PSD.MethodWe conducted an online survey using the discrete choice experiment (DCE) method. The DCE task involved participants choosing the best treatment option when presented with a set of competing hypothetical treatment profiles. Participants with symptomatic PSD referred for elective surgery were recruited from 33 National Health Service trusts between 2020 and 2022. Collected DCE data were analysed using regression analyses.ResultsIn all, 111 participants completed the survey. In the overall group, low risk of infection/persistence was the most important characteristic when making a treatment decision (attribute importance score 70%), followed by treatments with shorter recovery time with an attribute importance score of 30%. The results demonstrated that patients are willing to accept trade‐offs between treatment recovery time and risk of infection/persistence. Patients above 30 years old are willing to accept a higher chance of treatment failure in exchange for rapid treatment recovery (risk tolerance between 22.35 and 34.67 percentage points). Conversely, patients in the younger age groups were risk averse and were only willing to accept a small risk of 1.51–2.15 in exchange for a treatment with faster recovery time. All patient groups appear to the reject the excision and leave open technique due to the need for protracted nursing care.ConclusionThis study highlights the need for shared decision making when it comes to surgery for PSD.
