Background Context: Preoperative (pre-op) identification of patients likely to achieve a clinically meaningful improvement following surgery for adult spinal deformity (ASD) is critical, especially given the substantial cost and comorbidity associated with surgery. Even though pain is a known indication for surgical ASD correction, we are not aware of established thresholds for baseline pain and function to guide which patients have a higher likelihood of improvement with corrective surgery.

Purpose: We aimed to establish pre-op patient-reported outcome measure (PROM) thresholds to identify patients likely to improve by at least one minimum clinically important difference (MCID) with surgery for ASD.

Using Patient-Reported Outcomes Measurement Information System Physical Function (PROMIS PF) computerized adaptive test instead of the Knee injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS, JR) could reduce question burden for patients with knee pain. We aimed to prospectively determine the correlation between PROMIS PF and KOOS, JR to assess whether PROMIS PF could be a useful alternative measure for both research and clinical care of patients with knee pain. This was a cross-sectional study of 88 patients.

Studying the relative impact of various measures of coping strategies can help determine which ones are most useful for patients with osteoarthritis (OA).This study prospectively enrolled 108 patients with hip or knee OA who were seeing an orthopedic surgeon before or after arthroplasty. Measures of coping strategies included the Patient Activation Measure (PAM), Pain Self-Efficacy Questionnaire (PSEQ-2), and the Brief Resilience Scale (BRS).

Background: Despite increasing interest in total joint arthroplasty registries, evidence of the impact of physician-level performance on the value of care provided to patients undergoing hip and knee arthroplasty is lacking. The purpose of this study was to examine the effectiveness of an unblinded orthopaedic surgeon-specific value scorecard in improving patient outcomes and reducing hospital costs.

Methods: We retrospectively analyzed patient outcomes and hospital costs associated with total joint arthroplasties before and 9 months after the introduction of a Surgeon Value Scorecard at an urban tertiary care center.

Background: Limited access to specialty care for uninsured and underinsured patients may be exacerbated by traditional fee-for-service approaches to care that incentivize volume and intensity of services over value of care. The purpose of this study was to determine the impact of a value-based integrated practice unit (IPU) on access to musculoskeletal care and surgical outcomes in a safety-net population.

Methods: A new IPU was implemented on 6/1/2016 at an established safety-net clinic providing musculoskeletal care in central Texas to supplement existing musculoskeletal care provided through a fee-for-service model.

Background: Preoperative optimization of risk factors has been suggested as a strategy to improve the value of total joint arthroplasty (TJA) care. We assessed the implementation of a TJA preoperative optimization protocol and its impact on length of hospital stay, discharge destination, 90-day readmissions, and hospital direct variable costs.

Methods: This retrospective cohort study included adults undergoing primary elective TJA from 07/2015-09/2016 at an urban tertiary care hospital.

Study Design: Retrospective review of prospectively collected data.

Objective: To assess the clinical impact and economic burden of the three most common hospital-acquired conditions (HACs) that occur within 30-day postoperatively for all spine surgeries and to compare these rates with other common surgical procedures.

Summary Of Background Data: HACs are part of a non-payment policy by the Centers for Medicare and Medicaid Services and thus prompt hospitals to improve patient outcomes and safety.

 Obtaining wrist radiographs prior to surgeon evaluation may be wasteful for patients ultimately diagnosed with de Quervain tendinopathy (DQT).  Our primary question was whether radiographs directly influence treatment of patients presenting with DQT. A secondary question was whether radiographs influence the frequency of injection and surgical release between cohorts with and without radiographs evaluated within the same practice.

Background: Although patient-reported outcomes measures (PROMs) provide valuable health information and aid medical decision making for patients with hip and knee arthritis, survey completion rates remain low. The purpose of this study is to elucidate patient preferences regarding location of completion, delivery method, and barriers or facilitators to pre-visit completion.

Methods: Patients with hip and/or knee pain who were asked to complete pre-visit PROMs at 2 urban arthroplasty clinics were recruited.

Purpose: It remains unclear which factors, patient- or disease-specific, are associated with electing to undergo operative management for de Quervain tendinopathy. Our null hypothesis was that no patient- or disease-specific factors would be associated with the choice of surgical treatment of de Quervain tendinopathy.

Methods: We performed a retrospective review of consecutive patients diagnosed with de Quervain tendinopathy over 3 years by 1 of 3 fellowship-trained hand surgeons at an urban academic institution.

Objectives: To assess whether education during hospitalization after an acute fracture changes patient attitudes toward smoking-related complications and to assess whether this change persists into the first outpatient follow-up visit.

Design: Prospective, randomized, controlled trial.

Setting: Level 1 trauma center.

Background: Minor events that occur in the workplace sometimes are evaluated with MRI, which may reveal age-related changes in the symptomatic body part. These age-related changes are often ascribed to the event. However, evidence of similar or worse pathophysiology in the contralateral joint would suggest that the symptoms might be new, but the pathophysiology is not.
