Physiotherapists' Experiences with the Hip Disability and Knee Injury Osteoarthritis Outcome Score Following Total Hip and Knee Arthroplasty: A Qualitative Interview Study.

Background

Clinical guidelines for physiotherapy following total hip and knee arthroplasty (THA/TKA) recommend using Patient-Reported Outcome Measures (PROMs) like the Hip disability and Knee injury Osteoarthritis Outcome Score (HOOS/KOOS). However, it remains unclear how physiotherapists use these PROMs in daily clinical practice.

Objective

To explore primary care physiotherapists' experiences with the HOOS/KOOS in daily clinical practice following THA and TKA.

Methods

Thirteen physiotherapists in the Netherlands were recruited via convenience sampling. Data were collected through semi-structured interviews, which explored HOOS/KOOS use in clinical practice, administrative regulations, and applications beyond patient care, as well as think-aloud interviews to capture perceptions of the content of these PROMs and interpretations of hypothetical patient scores. Interviews were analysed using reflexive thematic analysis.

Results

The physiotherapists' ages ranged from 25 to 54y, with annual THA/TKA volumes from 5 to 50 patients. Three themes emerged, as follows: (1) "Physiotherapists use the HOOS/KOOS for various purposes in daily clinical practice", including complementing history taking and monitoring patient progress; (2) "Perceptions of the relevance of the HOOS/KOOS for daily clinical practice vary per item, domain, and version," with items related to daily life activities and psychosocial factors being perceived as more valuable; and (3) "Practical aspects of HOOS/KOOS administration influence their use in daily clinical practice," with electronic health records (EHRs) that facilitate PROM administration enhancing their use, while administrative regulations limit this.

Conclusions

Physiotherapists experience HOOS/KOOS items related to daily life activities and psychosocial factors useful for history-taking and monitoring patient progress, particularly when embedded in EHRs that facilitate PROM administration.
