The Single Assessment Numeric Evaluation (SANE) will correlate with and be equal to or superior in responsiveness to other outcome measures that have been employed in a stand-alone fashion in patients following total shoulder arthroplasty. The SANE was collected simultaneously with the ASES, WOOS, and SST in a retrospective analysis of a database of patients undergoing total shoulder arthroplasty. The Pearson coefficient was used to determine correlations. A sub-group study was carried out to see if the correlations differed in the determinations of preoperative outcome and postoperative outcome. The standardized response mean (SRM) and the effect size (ES) of both scores measured responsiveness. The relevance of the SANE and ASES was investigated using 150 consecutive patients to assess the number of unanswered questions in each score. The SANE and ASES (n=1447; r=0.82; p<0.0001), the WOOS (n=1514; r=0.83; p<0.0001), and the SST (n=1095; r=0.81; p<0.0001) all had high correlation. When comparing the SANE with all three measures, there was a moderate correlation between preoperative scores and a strong-moderate correlation between postoperative ratings. The SRM of the SANE = 2.2, ASES = 2.3, WOOS = 1.4, and SST=1.6 indicated that all scores were very responsive. The SANE had an ES of 2.9, ASES had an ES of 2.9, WOOS had an ES of 2.9, and the SST had an ES of 2.3. 100% of the SANE questions were completed completely, compared to 61% (P<0.0001) of the ASES questions.

The SANE strongly correlates with the WOOS, ASES, and SST, which have been utilized as stand-alone shoulder-specific outcomes measures in patients with total shoulder arthroplasty. With a large reduction in respondent burden, the SANE may provide the same information as the WOOS, ASES, and SST in terms of results. The SANE can be used as a stand-alone tool for patients undergoing total shoulder arthroplasty, which makes sense.
