Exploring appropriateness criteria for informing the total knee arthroplasty decision-making process: An interpretive descriptive study

Rational: The Hawker appropriateness criteria for total knee arthroplasty (TKA) are: osteoarthritis symptoms impacting quality of life, evidence of osteoarthritis, trial of conservative treatments, patient's realistic expectations, patient/surgeon agree benefits outweigh risks, and readiness for surgery. Little is known about the barriers and facilitators of using the Hawker et al. appropriateness criteria for TKA in clinical practice.

Aims and objectives: Explore the barriers and facilitators to using appropriateness criteria for TKA in making decisions for adults with knee osteoarthritis.

Methods: Interpretive descriptive qualitative study at an academic hospital. Purposive sampling aimed to recruit: (1) healthcare team members at all levels influencing care delivery, and (2) adults with TKA assessed at the hospital clinic. Semi-structured interviews asked about the barriers/facilitators to using the Hawker appropriateness criteria. Data analysis consisted of inductive thematic analysis with themes mapped to the Consolidated Framework for Implementation Research domains.

Results: Nine healthcare professionals and 14 adults with TKA participated and identified common barriers to using the Hawker appropriateness criteria: (a) intervention characteristics domain: difficulty to assess criteria, patients expecting healthcare professionals to decide, limited accessibility to conservative treatments; (b) individuals characteristics domain: no need to change current TKA process, clinical judgement limited to OA severity/age, implicit assessment of subjective criteria; (c) inner setting domain: TKA information received after decision made; and (d) outer setting domain: no timely access to TKA. A facilitator of use was evidence/buy-in fosters programme changes.

Conclusion: Barriers to using the criteria relevant to clinical practice and the healthcare system were identified while only one facilitator was revealed. Interventions tailored to these barriers are needed to support the use of the Hawker appropriateness criteria in TKA decision-making.
