Can patient satisfaction with decisions predict compliance with surgery?

Abstract

BACKGROUND: Patient satisfaction with treatment decisions is a discrete and measurable component of the satisfaction paradigm, distinct from satisfaction with health care services. OBJECTIVE: The study goal was to determine if the Satisfaction With Decision (SWD) scale, a valid and reliable 6-item survey, can predict patient compliance with surgery proposed by their otolaryngologist. DESIGN: Prospective study using the SWD scale plus measures of office visit satisfaction, provider satisfaction, and disease-specific quality of life. SETTING: Metropolitan, private nonprofit hospital. PATIENTS: The study population consisted of 151 patients scheduled for surgery, with a median age of 5.8 years and an age range of 0.6 to 65.3 years. INTERVENTIONS: At the time surgery was scheduled, the decision-maker completed a 12-item questionnaire about satisfaction and quality of life that included the SWD scale. Noncompliant patients were contacted, and the specific reason for cancellation was ascertained. RESULTS: The strongest predictor of surgical cancellation was the SWD survey score, with a median value of 4.8 for patients completing surgery compared with 3.8 for those who cancelled (P < 0.001). Patients with scores <4.0 had a 57% cancellation rate, whereas those with scores >4.0 had a 98% completion rate. Patients were also more likely to cancel if it was their first visit with the surgeon (P = 0.004) or if they were responsible for their own decisions ( P = 0.007). Cancellations were not associated with office visit satisfaction, patient quality of life, or demographic characteristics of the decision-maker. CONCLUSIONS: Patients who are satisfied with their initial decision to undergo surgery are most likely to comply with planned therapy. Conversely, patients who score <4.0 on the SWD scale may benefit from additional preoperative counseling to increase the likelihood of compliance.
