Long-Term Follow-Up of Inpatients with Rotator Cuff Tear Who Received Integrative Korean Medicine Treatment: A Retrospective Analysis and Questionnaire Survey.

CONTEXT

Rotator cuff tear is one of the most common causes of shoulder pain and has become a prominent disease most frequently treated by surgery.

OBJECTIVES

To investigate the long-term therapeutic effect of integrative Korean medicine (KM) as a conservative treatment in treating rotator cuff tears.

DESIGN

A multicenter observational study.

SETTINGS

The settings involve four regional network KM hospitals.

PATIENTS

The study participants are 288 patients aged 19-70 with rotator cuff tear identified by radiologist based on magnetic resonance imaging who received integrative KM treatment for the chief complaint of shoulder pain between 1 January 2015 and 31 March 2020.

INTERVENTION

None.

MAIN OUTCOMES

The primary outcome was the pain score in the affected shoulder, measured by the numeric rating scale (NRS). The secondary outcomes were Shoulder Pain and Disability Index (SPADI), 5-Level Quality of life: EuroQol 5-Dimension (EQ-5D-5L), Patient Global Impression of Change (PGIC), and range of motion (ROM) scores.

RESULTS

Eligible patients for MCID achievement analysis for minimally clinical important change were 167, and 109 completed the follow-up survey. The mean NRS pain score in the affected shoulder was 5.80 ± 1.27 at admission, 3.50 ± 1.32 at discharge, and 3.83 ± 2.04 at follow-up.The mean SPADI score was 51.48 ± 20.18 at admission, 37.76 ± 19.23 at discharge, and 24.26 ± 21.80 at follow-up. The improvement at discharge (P-value < 0.001) and follow-up (P-value < 0.001) compared to those at admission was statistically significant. The results also presented a significant improvement in ROM for all motions at discharge after treatment (P-value < 0.001). The number of patients who achieved minimal clinically important difference in NRS was 116 (69.5%) at discharge and 71 (65.1%) at follow-up, and in SPADI was 82 (50.9%) at discharge and 77 (70.6%) at follow-up.

CONCLUSION

The results of this study suggested that integrative KM treatment can help improve pain, functional impairment, QoL, and ROM in patients with a rotator cuff tear TRIAL REGISTRATION: NCT04566939.
