The Correlation Between a Numerical Rating Scale of Patient Satisfaction With Current Management of an Upper...

Background: Patient satisfaction is used as an indicator of quality of care, but the measures currently available are lengthy and cumbersome and may not be feasible in orthopedic surgical practices. We set out to assess the relationship between the Medical Interview Satisfaction Scale (MISS-21) and a numerical rating scale (NRS) of patient satisfaction with current management of an orthopedic upper extremity condition. Methods: In this cross-sectional study, 86 patients from the practices of 2 hand surgeons were included during an initial or follow-up visit. Questionnaires assessing demographics, upper extremity specific disability, pain during rest and activity, satisfaction with the medical visits (MISS-21), and satisfaction with current management of an orthopedic upper extremity condition (NRS satisfaction) were completed. Results: Eighty-six patients completed all questionnaires. A small correlation of .21 (P = .050) was found between the MISS-21 and the NRS satisfaction. In bivariate analysis, NRS pain at rest and during activity had small correlations with the MISS-21 (-.29, P = .05 and -.23, P = .034) and with NRS satisfaction (-.27, P = .011 and -0.27, P = 0.012). Quick Disability of Arm, Shoulder and Hand (QuickDASH) had a small correlation with NRS satisfaction (-0.023, P ≤ 0.001), but did not correlate with MISS-21. Conclusions: Although there is small overlap about the 2 satisfaction measures, a complex patient satisfaction questionnaire consisting of multiple facets of patient satisfaction like MISS-21 is not replaceable by 1 simple NRS patient satisfaction question.
