Preliminary insights into patient preparedness for knee or hip arthroplasty: a descriptive survey study

Knowledge-based preparedness for surgery is achieved through education. It is unclear which of brief or extended education programs prior to knee or hip arthroplasty provides better patient preparedness. Using the Patient Preparedness for Surgery survey, we investigated whether people awaiting arthroplasty attending a hospital that provided education over multiple visits via a pre-surgery management program ('Extended') report superior preparedness compared to those attending a hospital in the same health district that only provides education at the pre-admission clinic assessment ('Brief').

A consecutive sample of 128 people (n = 101, 'Extended', n = 27 'Brief') completed the anonymized survey. COVID-19 related service disruptions undermined the sample size, reducing statistical power. The pre-specified superiority of the Extended program (a relative 20% more reporting 'agree'/'strongly agree') was not observed for 'Overall preparedness' [95% (Extended) vs. 89% (Brief), p = 0.36]. Between-group differences exceeding 20% relative superiority were observed for three preparedness sub-domains ['Alternatives explained' (52 vs. 33%, p = 0.09); 'Prepared for home' (85 vs. 57%, p < 0.01); 'Recall of complications' (42 vs 26%, p = 0.14)]. The preliminary findings suggest an extended education program potentially yields better patient-reported preparedness in some preparedness sub-domains, but not all.
