Digital musculoskeletal program is associated with decreased joint replacement rates.

OBJECTIVES: To compare 12-month total knee arthroplasty (TKA) and total hip arthroplasty (THA) rates for digital musculoskeletal (MSK) program members vs patients who received traditional care for knee or hip osteoarthritis (OA). STUDY DESIGN: Retrospective, longitudinal study with propensity score-matched comparison group that used commercial medical claims data representing more than 100 million commercially insured lives. METHODS: Study participants with hip OA (M16.x) or knee OA (M17.x) International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) codes were identified in the medical claims database. Digital MSK program members were identified using record linkage tokens. The comparison group had hip- or knee-related physical therapy identified via ICD-10-CM and Current Procedural Terminology codes. Respectively in each knee and hip OA group, digital members were matched to control group patients with similar demographics, comorbidities, and baseline MSK-related medical care use. TKA and THA at 12 months post participation were compared. RESULTS: In the knee OA group, 739 of 56,634 control group patients were matched to 739 digital members. At 12 months, 3.79% of digital members and 14.21% of control group patients had TKA (difference, 10.42%; P < .001). In the hip OA group, 141 of 20,819 control group patients were matched to 141 digital members. At 12 months, 16.31% of digital members and 32.62% of control group patients had THA (difference, 16.31%; P = .001). CONCLUSIONS: These findings suggest that patients who participated in a digital MSK program to manage OA have lower rates of total joint arthroplasty in the 12 months after enrollment.

Opioid Initiation Within One Year After Starting a Digital Musculoskeletal (MSK) Program: An Observational, Longitudinal Study with Comparison Group.

Background: In-person, conservative care may decrease opioid use for chronic musculoskeletal (MSK) pain, but the impact of digitally delivered conservative care on opioid use is unknown. This study examines associations between a digital MSK program and opioid initiation and prescriptions among opioid naive adults with chronic MSK pain. Methods: This observational study used commercial medical and pharmacy claims data to compare digital MSK program members to matched physical therapy (PT) patients. Outcomes were any opioid prescriptions and opioid prescriptions per 100 participants within the 12-months after starting a digital MSK program. After propensity-score matching, we conducted multivariate regression models that controlled for demographic, comorbidity, and baseline MSK healthcare use. Results: The study included 4195 members and 4195 matched PT patients. For opioid initiation, 7.89% (95% Confidence Interval [CI]: 7.07%, 8.71%) of members had opioid prescriptions within 12 months after starting the digital MSK program versus 13.64% (95% CI: 12.60%, 14.67%) of matched PT patients (p < 0.001). Members had significantly fewer opioid prescriptions (16.73 per 100 participants; 95% CI: 14.11, 19.36) versus PT patients (22.36 per 100 participants; 95% CI: 19.99, 24.73). Members had lower odds (OR: 0.52, 95% CI: 0.45, 0.60) of initiating opioids and significantly fewer prescriptions per 100 participants (beta: -6.40, 95% CI: -9.88, -2.93) versus PT patients after controlling for available confounding factors. Conclusion: An MSK program that delivers conservative care digitally may be a promising approach for decreasing opioid initiation among individuals with chronic MSK pain given the limitations of the observational design and matching on only available covariates.
