Effects of a medical second opinion program on patients’ decision for or against knee arthroplasty.

Abstract

Background

German social legislation gives patients the right to obtain a second opinion before elective surgery and defines quality criteria for reimbursement by statutory health insurance. However, the effects of second opinions before elective surgery are largely unknown. This study evaluated the effects of a second opinion program in patients recommended for knee arthroplasty.

Methods

The largest statutory health insurance funds in Bavaria offered patients who had been recommended to have knee arthroplasty the opportunity to participate in a second opinion program, which consisted of an in-person presentation to an experienced knee surgeon. This cohort study included consecutive patients from this second opinion program who signed informed consent from 07/10/2016 to 14/02/2020. Data were collected before and after the second opinion visit.

Results

A total of 141 (66%) of 215 patients who presented for a second opinion participated in the evaluation study. The second opinion physician recommended knee arthroplasty to 40% of the patients, later knee arthroplasty if the conditions worsened to 40%, and no knee arthroplasty to 20%. After receiving the second opinion, 28 of 56 (41%) undecided patients preferred knee arthroplasty, 14 had no knee arthroplasty, and 14 remained undecided. Four of 46 patients with a preference for “arthroplasty” changed their decision to “no arthroplasty,” and five of 35 patients changed from “no arthroplasty” to “arthroplasty.” The patients were more confident in their decision according to the decision confidence scale (before: 5.4 ± 3.0; after: 7.8 ± 2.5; p < 0.001). They rated their satisfaction with the second opinion program with a mean grade of 1.35 (± 0.60) (best:1; worst:6). Logistic regression analyses showed that the recommendation of the second opinion physician for joint arthroplasty was associated with the guideline criteria radiological severity of osteoarthritis (p = 0.001) and knee-joint-specific quality of life (p = 0.041).

Conclusion

The second opinion of an experienced knee surgeon frequently deviates from the initial recommendation for knee arthroplasty. The association of guideline criteria to the second recommendation suggests a high quality of the second opinion. From the patient’s perspective, the second opinion reduces uncertainties in their treatment decision.
