Clinical reasoning in managing chronic hip pain: One in two Australian and New Zealand physiotherapists diagnosed a case vignette with clinical criteria for hip OA as hip OA. A cross-sectional survey.

Abstract

Using a case vignette of an adult (George) presenting with hip pain consistent with hip OA, this study aimed to describe: (a) whether physiotherapists make diagnoses and identify bodily structures using either patient history and/or physical examination findings; (b) which diagnoses and bodily structures physiotherapists attribute to the hip pain; (c) how confident physiotherapists were in their clinical reasoning using patient history and physical examination findings; (d) what treatments physiotherapists would offer to George. We conducted a cross-sectional online survey of physiotherapists in Australia and New Zealand. We used descriptive statistics to analyse closed questions and content analysis for open-text responses. Two hundred and twenty physiotherapists completed the survey (39% response-rate). After receiving the patient history, 64% diagnosed George's pain and 49% of these as hip OA; 95% attributed George's pain to a bodily structure(s). After receiving the physical examination, 81% diagnosed George's hip pain and 52% of these as hip OA; 96% attributed George's hip pain to a bodily structure(s). Ninety-six percent of respondents were at least somewhat confident in their diagnosis after the patient history, and 95% were similarly confident after the physical examination. Most respondents offered advice (98%) and exercise (99%), but fewer offered treatments for weight loss (31%), medication (11%), and psychosocial factors (<15%). About half of the physiotherapists that diagnosed George's hip pain made a diagnosis of hip OA, despite the case vignette including clinical criteria for a diagnosis of OA. Physiotherapists offered exercise and education, but many physiotherapists did not offer other clinically indicated and recommended treatments, such as weight loss and sleep advice.
