Abstract

Background: Patient knowledge about arthritis and risks, benefits, and outcomes of joint arthroplasty in developing countries is unknown. We evaluated the effectiveness of a preoperative class on improving knowledge and decreasing anxiety during a surgical mission trip offering total joint arthroplasty. Methods: A team of US health care providers taught a preoperative class to 41 patients selected for total joint arthroplasty during a surgical mission trip to Guyana. Participants completed a 32-point survey about arthritis; indications, risks, and benefits of joint arthroplasty; and postoperative, in-patient rehabilitation expectations. The State-Trait Anxiety Inventory was used to measure participant anxiety. Participants completed identical surveys before and after class. Matched-pairs Student t tests were used to compare means between preclass and postclass surveys. Significance was accepted at P < .05. Results: Seventy-eight percent of patients (31 of 41) scored less than 12 of 32 possible points (40%) on the preclass knowledge questionnaire. Mean ± standard deviation knowledge scores improved from 14.0 ± 4.5 before the class to 16.5 ± 6.5 after the class (P = .008). Anxiety scores (n = 33) improved from 35 ± 13 before the class to 33 ± 12 after the class (P = .047). Conclusion: On this surgical mission trip, underserved patients' knowledge about total joint arthroplasty increased only modestly after taking a preoperative class. Greater understanding of how to educate patients and reduce their anxiety on medical missions is needed.
