Preoperative patient-reported outcome score thresholds predict the likelihood of reaching MCID with surgical correction of adult spinal deformity.

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. STUDY DESIGN: This is a retrospective cohort study using prospectively collected data. PATIENT SAMPLE: We reviewed 172 adult patients' charts who underwent corrective surgery for spinal deformity. OUTCOME MEASURES: Included measures were the Visual Analog Scale for pain (VAS), Oswestry Disability Index (ODI), and Scoliosis Research Society-22 (SRS-22). Our primary outcome of interest was improvement by at least one MCID on the ODI and SRS-22 at 2 years after surgery. METHODS: As part of usual care, the VAS, ODI, and SRS-22 were collected pre-op and re-administered at 1, 2, and 5 years after surgery. MCIDs were calculated using a distribution-based method. Determining significant predictors of MCID at two years was accomplished by Firth bias corrected logistic regression models. Significance of predictors was determined by Profile Likelihood Chi-square. We performed a Youden analysis to determine thresholds for the strongest pre-op predictors. RESULTS: At year two, 118 patients (83%) reached MCID for the SRS and 127 (75%) for the ODI. Lower pre-op SRS overall, lower pre-op SRS pain, and higher pre-op SRS function predicted a higher likelihood of reaching MCID on the overall SRS (p < 0.05). Higher pre-op ODI, lower SRS pain and self-image, and higher SRS overall predicted a higher likelihood of reaching MCID on the ODI (p < 0.05). An ODI threshold of 29 predicted reaching MCID with a sensitivity of 0.89 and a specificity of 0.64 (AUC = 0.7813). An SRS threshold of 3.89 predicted reaching MCID with a sensitivity of 0.93 and specificity of 0.68 (AUC = 0.8024). CONCLUSIONS: We identified useful thresholds for ODI and SRS-22 with acceptable predictive ability for improvement with surgery for ASD. Pre-op ODI, SRS, and multiple SRS subscores are predictive of meaningful improvement on the ODI and/or SRS at 2 years following corrective surgery for spinal deformity. These results highlight the usefulness of PROMs in pre-op shared decision-making.

PROMIS Physical Function Correlates with KOOS, JR in Patients with Knee Pain.

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. We assessed the correlation between PROMIS PF and KOOS, JR using a Pearson's correlation test. Two multivariable linear regression models were used to determine the amount of variation explained by various patient-level factors. There was a strong correlation between PROMIS PF and KOOS, JR (r = 0.74, p < 0.001). KOOS, JR was an independent predictor of PROMIS PF when controlling for patient-level factors (ß 0.26; p < 0.001). The results of this study support the idea of using PROMIS PF in place of joint-specific measures such as KOOS, JR for clinical care of patients with knee pain. The level of evidence for this study is Level III.

Influence of Patient Activation, Pain Self-Efficacy, and Resilience on Pain Intensity and Magnitude of Limitations in Patients With Hip and Knee Arthritis.

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). The Hip Disability and Osteoarthritis Outcome Score, Junior (HOOS, JR), the Knee Injury and Osteoarthritis Outcome Score, Junior (KOOS, JR), and Numeric Rating Scale (NRS) were used to measure pain intensity. Pearson correlations measured the interrelationships of the outcome measures. The PSEQ-2 correlated significantly with the NRS, but the confidence intervals for the three instruments overlapped. The PAM and the PSEQ-2 correlated with the KOOS, JR. Only the PSEQ-2 was associated with variation in the NRS. The PAM, PSEQ-2, and BRS correlated with one another. While measures of self-efficacy, active involvement in care, and general resilience were correlated, the measure of pain self-efficacy had the strongest association with patient-reported outcomes.

A Surgeon Scorecard Is Associated with Improved Value in Elective Primary Hip and Knee Arthroplasty.

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. From August 2016 to May 2017, orthopaedic surgeons received an unblinded monthly Surgeon Value Scorecard summarizing a rolling 6-month view of results by surgeon for patients attributed to Diagnosis Related Group 470 (major lower-extremity arthroplasty without comorbidity or complication). Prior to implementation, surgeons were educated on the scorecard and participated in the development of a document outlining the definition and calculation of included metrics. Scorecard metrics were grouped into 5 categories: patient demographic characteristics, patient outcomes (for example, length of stay, discharge disposition, readmissions), patient experience, financial, and operational (for example, operative times). Financial (cost) measures and patient outcomes were selected as the key performance indicators analyzed in this study. Continuous variables were analyzed using the t test when a normal distribution was assumed and using Mann-Whitney tests when a non-normal distribution was assumed. Categorical variables were compared using chi-square tests. Significance was defined as p < 0.05. RESULTS: After 9 months of unblinded Surgeon Value Scorecard distribution, the mean total costs for total joint arthroplasties decreased by 8.7%, from $17,996 to $16,426 (p < 0.001). The mean total direct variable costs decreased by 17.1% from $10,945 to $9,070 (p < 0.001), and implant costs decreased by 5.3% (p < 0.001). Length of stay also decreased by 0.2 day to 1.7 days (p < 0.001), and, although there was improvement in the home-discharge rate, 30-day readmission rate, and 90-day readmission rate, the differences were not significant (p > 0.05). CONCLUSIONS: The implementation of a surgeon-specific value scorecard for lower-extremity joint arthroplasties was associated with reduced total and direct variable hospital costs, reduced implant costs, decreased variation in costs, and reduced postoperative length of stay, without compromising clinical outcomes. CLINICAL RELEVANCE: Sharing unblinded clinical and financial outcomes with surgeons may promote a culture of shared accountability and may empower surgeons to improve value-based decision-making in care delivery.

Impact of an integrated practice unit on the value of musculoskeletal care for uninsured and underinsured patients.

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. This retrospective cohort study compared access and outcomes under the IPU to the parallel fee-for-service clinic through 3/31/2017, as well as the historical fee-for-service clinic from 8/1/2015 through 5/31/2016. Primary outcomes for access included number of referrals addressed; for surgical patients, length of stay, discharge destination, and 30-day readmission rates were assessed. RESULTS: The baseline waitlist of 1401 referrals on 6/1/2016 was eliminated by 3/31/2017. Among patients undergoing hip or knee replacement, length of stay was 1.4 days compared to 2.6 days for patients referred to the parallel fee-for-service clinic (p < 0.001), and 92% were discharged home versus 89% (p = 0.46). The 30-day readmission rate for the IPU was 2.7%, which did not differ significantly from the HFFS (8.5%, p = 0.23) and PFFS (3.7%, p = 0.64) clinics. CONCLUSIONS: An IPU increased access and improved short-term surgical outcomes in a population of uninsured and underinsured patients seeking musculoskeletal care. Additional studies of longer duration are needed to assess the sustainability of a value-based approach. IMPLICATIONS: A value-based approach to musculoskeletal care may improve access and outcomes in safety-net patients. LEVEL OF EVIDENCE: III, retrospective cohort study.

Evaluation of a Preoperative Optimization Protocol for Primary Hip and Knee Arthroplasty Patients.

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. Post-implementation patients were preoperatively screened for 19 risk factors; results and recommended interventions were reported to surgeons, who had the option to postpone or continue surgery as scheduled. Metrics from hospital administrative databases were compared between post-implementation (02/2016-09/2016) and pre-implementation cohorts (07/2015-11/2015). RESULTS: The 314 post-implementation patients were slightly younger compared to the 351 pre-implementation patients (64.2 years vs 65.8 years, P = .02) and a higher percentage of patients had diabetes (18% vs 5.1%, P < .001). Of the 98% of post-implementation patients screened, 74% had at least 1 risk factor identified. Obstructive sleep apnea was the most common risk factor (52%), followed by depression (22%) and obesity (body mass index > 40 kg/m2 or 35-40 kg/m2 with comorbidities) (13%). Forty-six patients (20%) did not follow through with the recommended optimization before undergoing elective surgery. The post-implementation cohort had shorter average length of hospital stay (1.9 days vs 2.2 days, P < .001) and lower average total direct variable costs excluding implants ($5409 vs $5852, P < .001). There was no difference in patients discharged home (90% vs 89%, P = .53) or 90-day readmissions (4.1% vs 4.3%, P = .93). CONCLUSION: In our experience, the majority of elective TJA patients have modifiable risk factors, indicating opportunity for preoperative intervention. Our evidence-based preoperative optimization program resulted in higher value care, demonstrated by similar outcomes with lower resource utilization.

Clinical Impact and Economic Burden of Hospital-Acquired Conditions Following Common Surgical Procedures.

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. METHODS: Patients more than 18 years who underwent elective spine surgery were identified in American College of Surgeons' National Surgical Quality Improvement Program (ACS-NSQIP) database from 2005 to 2013. Primary outcomes were cost associated with the occurrence of three most common HACs. Cost associated with HAC occurrence derived from the PearlDiver database. RESULTS: Ninety thousand five hundred fifty one elective spine surgery patients were identified, where 3021 (3.3%) developed at least one HAC. Surgical site infection (SSI) was the most common HAC (1.4%), then urinary tract infection (UTI) (1.3%) and venous thromboembolism (VTE) (0.8%). Length of stay (LOS) was longer for patients who experienced a HAC (5.1 vs. 3.2 d, P < 0.001). When adjusted for age, sex, and Charlson Comorbidity Index, LOS was 1.48 ±â€Š0.04 days longer (P < 0.001) and payments were $8893 ±â€Š$148 greater (P < 0.001) for patients with at least one HAC. With the exception of craniotomy, patients undergoing common procedures with HAC had increased LOS and higher payments (P < 0.001). Adjusted additional LOS was 0.44 ±â€Š0.02 and 0.38 ±â€Š0.03 days for total knee arthroplasty and total hip arthroplasty, and payments were $1974 and $1882 greater. HACs following hip fracture repair were associated with 1.30 ±â€Š0.11 days LOS and $4842 in payments (P < 0.001). Compared with elective spine surgery, only bariatric and cardiothoracic surgery demonstrated greater adjusted additional payments for patients with at least one HAC ($9975 and $10,868, respectively). CONCLUSION: HACs in elective spine surgery are associated with a substantial cost burden to the health care system. When adjusted for demographic factors and comorbidities, average LOS is 1.48 days longer and episode payments are $8893 greater for patients who experience at least one HAC compared with those who do not.

Deferring Routine Wrist Radiography Does Not Affect Management of de Quervain Tendinopathy Patients.

Background Obtaining wrist radiographs prior to surgeon evaluation may be wasteful for patients ultimately diagnosed with de Quervain tendinopathy (DQT). Questions/Purpose 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. Patients and Methods Patients diagnosed with DQT by fellowship-trained hand surgeons at an urban academic medical center were identified retrospectively. Basic demographics and radiographic findings were tabulated. Clinical records were studied to determine whether radiographic findings corroborated history or physical examination findings, and whether management was directly influenced by radiographic findings. Frequencies of treatment with injection and surgery were separately tabulated and compared between cohorts with and without radiographs. Results We included 181 patients (189 wrists), with no differences in demographics between the 58% (110 wrists) with and 42% (79 wrists) without radiographs. Fifty (45%) of imaged wrists demonstrated one or more abnormalities; however, even for the 13 (12%) with corroborating history and physical examination findings, wrist radiography did not directly influence a change in management for any patient in this series. No difference was observed in rates of injection or surgical release either upon initial presentation, or at most recent documented follow-up, between those with and without radiographs. No differences in frequency, types, or total number of additional simultaneous surgical procedures were observed for those treated surgically. Conclusion Wrist radiography does not influence management of patients presenting DQT. Level of Evidence This is a level III, diagnostic study.

Patient-Identified Barriers and Facilitators to Pre-Visit Patient-Reported Outcomes Measures Completion in Patients With Hip and Knee Pain.

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. In-person, semi-structured, audio-recorded interviews were conducted, transcribed, and coded for thematic analysis. Codes were developed using a data-driven approach. RESULTS: We analyzed 51 interviews. The mean age was 57 years, 57% were women, and 45% had private or Medicare insurance. Prevalent themes regarding location preferences were convenience and communication preferences. Thirty-four patients stated a preference for completing pre-visit PROMs at home, 19 for in-office completion, and 10 stated no preference. Prevalent themes around delivery methods included technology access and familiarity. Of the 43 patients asked to select their preferred pre-visit PROM delivery method (phone call, email, text message, or postal mail), 31 (72%) preferred email or text messaging. Barriers to completing pre-visit PROMs were technological issues, recognizing the message was healthcare-related, and being too busy or forgetting. Twenty patients identified no barriers. CONCLUSION: Electronic PROM collection is favored by many patients, but alternative methods for patients without access to or familiarity with technology remain important. Clear recognition that the message is from a physician's office and physician communication of the utility of PROMs in clinical decision making may increase pre-visit completion.

Patient- and Disease-Specific Factors Associated With Operative Management of de Quervain Tendinopathy.

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. Descriptive statistics were calculated for patient baseline and disease-specific characteristics. Cohorts were compared using bivariate analysis for all collected variables. Binary logistic regression with backward stepwise term selection was performed including independent predictors identified by bivariate analysis. RESULTS: A total of 200 patients were identified for inclusion. Bivariate analysis revealed that surgically treated patients were significantly more likely to have Medicaid insurance, psychiatric illness history, and disabled work status. Regression analysis revealed an association between surgical treatment and 2 of the factors evaluated: Medicaid insurance status and psychiatric illness history. CONCLUSIONS: Psychiatric illness and Medicaid insurance status are associated with undergoing surgical release of the first dorsal compartment. These findings support the use of a biopsychosocial framework when treating patients with de Quervain tendinopathy. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

A Teachable Moment After Orthopaedic Fracture in the Smoking Patient: A Randomized, Controlled Trial.

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. PATIENTS: Inpatients with fractures who identified as smokers: 40 assessed for inclusion and randomized, 30 completed inpatient assessments, and 20 completed outpatient follow-up. INTERVENTION: An educational intervention by the researcher to teach the patient about the harms of smoking regarding fracture healing. MAIN OUTCOME MEASURES: A novel questionnaire to assess the intervention via Likert scale responses, evaluating perceived risk, affective response, and self-role. RESULTS: Education resulted in an increase in perceived risk and affective response within the cohort and an increase in perceived risk when compared with control subjects. No significant differences persisted into outpatient follow-up. CONCLUSIONS: This trial demonstrated that a teachable moment can have an early effect on certain attitudes toward smoking after an acute fracture. These changes did not persist at the first follow-up visit. LEVEL OF EVIDENCE: Therapeutic Level I. See Instructions for Authors for a complete description of levels of evidence.

Patients Older Than 40 Years With Unilateral Occupational Claims for New Shoulder and Knee Symptoms Have Bilateral MRI Changes.

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. QUESTIONS/PURPOSES: Using a convenience sample of occupational injury claimants with bilateral MRI to evaluate unilateral knee or shoulder symptoms ascribed to a single event at work, we sought to determine whether MRI findings of the shoulder and knee are more often congruent or incongruent with new unilateral symptoms. METHODS: Two hundred ninety-four occupational injury claimants employed at companies throughout Texas that do not subscribe to workers' compensation insurance, who were older than 40 years, and with unilateral shoulder or knee symptoms, were studied. Starting in 2012, all patients seen by OccMD Group PA who present with unilateral symptoms ascribed to work undergo bilateral MRI, based on several previous occasions where bilateral MRI proved to be a compelling demonstration that perceived injuries are more likely age-related, previously well-adapted pathophysiology. MRI findings (anything described as abnormal by the radiologist; eg, defect size or signal change) was considered congruent if the abnormality of one or more structures on the symptomatic side was greater than that of the corresponding structures in the asymptomatic joint. Bivariate analysis was used to compare the frequency of MRI findings congruent and incongruent with symptoms. Logistic regression was used to evaluate factors associated with MRI findings of the shoulder or knee. RESULTS: Less than half of the patients with shoulder (90 of 189; 48%; p = 0.36) or knee (45 of 105; 43%; p = 0.038) symptoms had worse pathologic features on the symptomatic side. Older age was associated with disorders in the infraspinatus tendon (59 ± 8 versus 56 ± 8 years; p = 0.012), glenoid labrum (60 ± 9 versus 57 ± 8 years; p = 0.025), and biceps tendon (60 ± 8 versus 57 ± 8 years; p = 0.0038). Eighty-seven percent of patients (91 of 105) had structural changes in the medial meniscus described by the radiologist. CONCLUSIONS: Occupational injury claimants 40 years of age and older with unilateral knee and shoulder symptoms ascribed to a work event tend to have bilateral age-related MRI changes. Age-related disorders should be distinguished from acute injury. LEVEL OF EVIDENCE: Level IV, diagnostic study.
