The American Shoulder and Elbow Score Is Highly Correlated With the Western Ontario Rotator Cuff Index and Has Less Responder and Administrator Burden.

ABSTRACT:

Purpose

To compare the correlation, responsiveness, and responder and administrator burdens of the American Shoulder and Elbow Score (ASES) with the Western Ontario Rotator Cuff Index (WORC) for patients undergoing arthroscopic rotator cuff repair to determine whether one score is superior to the other to limit the use of multiple scoring measures when tracking patient outcomes.

Methods

A retrospective review of a database of patients undergoing arthroscopic rotator cuff repair was reviewed where the ASES was simultaneously recorded with the WORC. Correlations were determined using the Pearson coefficient. Subgroup analysis was performed to determine if correlations differed in (1) preoperative outcome and (2) postoperative outcome determinations. Responsiveness was determined by calculating the standardized response mean and the effect size of both scores. Responder and administrator burden was examined using 50 consecutively scored WORC and ASES scores by determining the number of questions accurately answered and the length of time taken to score each questionnaire.

Results

Correlation was excellent for the ASES and WORC (r = 0.90). The correlation of preoperative scores was strong-moderate (r = 0.69), and the correlation of postoperative scores was excellent (r = 0.86). The standardized response mean WORC = 2.3; ASES = 2.2) and the effect size (WORC = 2.9; ASES = 2.8) demonstrated comparable responsiveness. In total, 71.5% of the WORC questions were able to be scored compared with 93.3% for the ASES (P < .0001). The mean time to score the WORC was significantly greater than the ASES (154 vs 23 seconds; P < .0001).

Conclusions

There is excellent correlation and comparable responsiveness between the ASES and WORC. Since there is greater responder and administrative burden for the WORC score, the authors recommend using the ASES over the WORC in patients undergoing rotator cuff repair.

Project description:BackgroundRotator cuff tears are a common cause of shoulder pain and can result in prolonged periods of pain, disability and absence from work. Rotator cuff repair surgery is increasingly used in an attempt to resolve symptoms but has failure rates of around 40%. There is a pressing need to improve the outcome of rotator cuff repairs. Patch augmentation increasingly being used within the NHS in an attempt to reduce repair failures. The aim of this survey was to determine current UK practice and opinion relating to the factors that influence choice of patch, current patient selection and willingness to assist with generation of improved evidence.MethodsAn online survey was sent to the surgeon members of the British Elbow and Shoulder Society (BESS). Questions covered respondent demographics, experience with patches, indications for patch augmentation and willingness to be involved in a randomised trial of patch augmented rotator cuff surgery.ResultsThe response rate was 105/550 (19%). 58% of respondents had used a patch to augment rotator cuff surgery. 70% of patch users had undertaken an augmented repair within the last 6 months. A wide surgical experience in augmentation was reported (ranging 1 to 200 implants used). However, most surgeons reported low volume usage, with a median of 5 rotator cuff augmentation procedures performed. At least 10 different products had been used. Most of the patches used were constructed from human decellularised dermis tissue, although porcine derived and synthetic based patches had also been used. Only 3-5% stated they would undertake an augmented repair for small tears across ages, whereas 28-40% and 19-59% would do so for large or massive tears respectively. When assessing patient suitability, patient age seemed relevant only for those with large and massive tears. Half of the surgeons reported an interest in taking part in a randomised controlled trial (RCT) evaluating the role of patch augmentation for rotator cuff surgery, with a further 22% of respondent's undecided.ConclusionsA variety of patches have been used by surgeons to augment rotator cuff repair with a wide range of operator experience. There was substantial uncertainty about which patch to use and differing views on which patients were most suitable. There is a clear need for robust clinical evaluation and further research in this area.

Project description:Purpose To compare patient-reported and surgical outcome measures in patients with and without secondary shoulder stiffness (SSS) undergoing rotator cuff repair (RCR). Methods Patients undergoing rotator cuff repair from 2014 to 2020 with complete patient-reported outcome measures (PROMs) by the short-form 12 survey (SF-12) were retrospectively reviewed to identify if operative intervention for SSS was performed alongside the RCR. Those patients with operative intervention for SSS were propensity matched to a group without prior intervention for stiffness by age, sex, laterality, body mass index, diabetes mellitus status, and the presence of a thyroid disorder. The groups were compared by rotator cuff tear (RCT) size, surgical outcomes, further surgical intervention, rotator cuff retear rate, postoperative range of motion (ROM), and SF-12 results at 1 year after surgery. Delta values were calculated for component scores of the SF-12 and ROM values by subtracting the preoperative result from the postoperative result. Results A total of 89 patients with SSS were compared to 156 patients in the control group at final analysis. The patients in the SSS group experienced a significant improvement in the delta mental health component score (MCS-12) of the SF-12 survey that was not seen in the control group (P = .005 to P = .539). Both groups experienced significant improvement by the delta physical health component score (PCS-12) of the SF-12 survey (SSS: 7.68; P < .001; control: 6.95; P < .001). The SSS group also experienced greater improvement of their forward flexion (25.8° vs 12.9°; P = .005) and external rotation (7.13° vs 1.65°; P = .031) ROM than the control group. Conclusions Operative intervention of SSS at the time of RCR has equivalent postoperative SF-12 survey outcome scores when compared to patients undergoing RCR without preoperative stiffness despite those patients having lower preoperative scores.
