Evaluating Shared Decision-Making in Treatment Selection for Dupuytren Contracture: A Mixed Methods Approach.

BACKGROUND

Patients with Dupuytren contracture can receive a variety of surgical and nonsurgical treatments. The extent to which patients participate in the shared decision-making process is unclear.

METHODS

An explanatory-sequential mixed-methods study was conducted. Participants completed the Nine-Item Shared Decision-Making Questionnaire and the brief Michigan Hand Outcomes Questionnaire before completing semi-structured interviews in which they described their experience with selecting treatment.

RESULTS

Thirty participants [25 men (83%) and five women (17%); mean age, 69 years (range, 51 to 84 years)] received treatment for Dupuytren contracture (11 collagenase injection, six needle aponeurotomy, and 13 limited fasciectomy). Adjusted mean scores for the Shared Decision-Making Questionnaire and brief Michigan Hand Outcomes Questionnaire were 71 (SD 20) and 77 (SD 16), respectively, indicating a high degree of shared decision-making and satisfaction. Patients who received limited fasciectomy accepted invasiveness and prolonged recovery time because they believed it provided a long-term solution. Patients chose needle aponeurotomy and collagenase injection because the treatments were perceived as safer and more convenient and permitted rapid return to daily activities, which was particularly valued by patients who were employed or had bilateral contractures.

CONCLUSIONS

Physicians should help patients choose a treatment that aligns with the patient's preferences for long-term versus short-term results, recovery period and postoperative rehabilitation, and risk of complications, because patients used this information to assist in their treatment selection. Areas of improvement for shared decision-making include equal presentation of all treatments and ensuring realistic patient expectations regarding the chronic and recurrent nature of Dupuytren contracture regardless of treatment received.
