A Poster Summarizing the American Academy of Orthopaedic Surgeons Knee Osteoarthritis Clinical Practice Guideline Is a Powerful Tool for Patient Education: A Randomized Controlled Trial.

BACKGROUND: In 2013, the American Academy of Orthopaedic Surgeons (AAOS) published an evidence-based clinical practice guideline (CPG) on conservative treatment options for patients with knee osteoarthritis (OA). The purpose of this study is to evaluate the effectiveness of a poster outlining the AAOS knee OA CPG on patient comprehension and satisfaction in the clinic. METHODS: This is a prospective 2-armed randomized controlled trial. Patients were eligible if they were of age 40-85 years, had degenerative knee OA, and did not consent for surgery. Patients were randomized to nonposter (standard care) and poster rooms. Knee OA treatment options were described to the patient verbally and posters were used as a teaching tool when present. The main outcomes were comprehension and satisfaction scores on a survey. RESULTS: Of the 105 patients enrolled, 51 (48.6%) were randomized to usual care (control) and 54 (51.4%) to the intervention (poster). Poster patients outperformed control patients with an average of 55.3% ± 16.7% (mean ± SD) compared to 39.5% ± 13.3% correct answers (P < .001). And 66.7% of poster patients and 29.4% of control patients achieved an adequately informed status of >50% correct answers (P < .001; 50.5% overall). With a maximum possible score of 10, visit satisfaction scores were 9.4 ± 1.0 in poster patients and 9.2 ± 1.7 in control patients (P = .50). CONCLUSION: Patients educated using an AAOS knee CPG poster showed significant improvements in knowledge and were more likely to achieve an adequately informed status. No difference existed in visit satisfaction. A poster offers a low-cost, effective educational tool. LEVEL OF EVIDENCE: Level 1.

Alternative Payment Models Should Risk-Adjust for Conversion Total Hip Arthroplasty: A Propensity Score-Matched Study.

BACKGROUND: For Medicare beneficiaries, hospital reimbursement for nonrevision hip arthroplasty is anchored to either diagnosis-related group code 469 or 470. Under alternative payment models, reimbursement for care episodes is not further risk-adjusted. This study's purpose was to compare outcomes of primary total hip arthroplasty (THA) vs conversion THA to explore the rationale for risk adjustment for conversion procedures. METHODS: All primary and conversion THAs from 2007 to 2014, excluding acute hip fractures and cancer patients, were identified in the National Surgical Quality Improvement Program database. Conversion and primary THA patients were matched 1:1 using propensity scores, based on preoperative covariates. Multivariable logistic regressions evaluated associations between conversion THA and 30-day outcomes. RESULTS: A total of 2018 conversions were matched to 2018 primaries. There were no differences in preoperative covariates. Conversions had longer operative times (148 vs 95 minutes, P < .001), more transfusions (37% vs 17%, P < .001), and longer length of stay (4.4 vs 3.1 days, P < .001). Conversion THA had increased odds of complications (odds ratio [OR] 1.75; 95% confidence interval [CI] 1.37-2.24), deep infection (OR 4.21; 95% CI 1.72-10.28), discharge to inpatient care (OR 1.52; 95% CI 1.34-1.72), and death (OR 2.39; 95% CI 1.04-5.47). Readmission odds were similar. CONCLUSION: Compared with primary THA, conversion THA is associated with more complications, longer length of stay, and increased discharge to continued inpatient care, implying greater resource utilization for conversion patients. As reimbursement models shift toward bundled payment paradigms, conversion THA appears to be a procedure for which risk adjustment is appropriate.

The Frank Stinchfield Award : Total Hip Arthroplasty for Femoral Neck Fracture Is Not a Typical DRG 470: A Propensity-matched Cohort Study.

BACKGROUND: Hip fractures are a major public health concern. For displaced femoral neck fractures, the needs for medical services during hospitalization and extending beyond hospital discharge after total hip arthroplasty (THA) may be different than the needs after THA performed for osteoarthritis (OA), yet these differences are largely uncharacterized, and the Medicare Severity Diagnosis-Related Groups system does not distinguish between THA performed for fracture and OA. QUESTIONS/PURPOSES: (1) What are the differences in in-hospital and 30-day postoperative clinical outcomes for THA performed for femoral neck fracture versus OA? (2) Is a patient's fracture status, that is whether or not a patient has a femoral neck fracture, associated with differences in in-hospital and 30-day postoperative clinical outcomes after THA? METHODS: The National Surgical Quality Improvement Program (NSQIP) database, which contains outcomes for surgical patients up to 30 days after discharge, was used to identify patients undergoing THA for OA and femoral neck fracture. OA and fracture cohorts were matched one-to-one using propensity scores based on age, gender, American Society of Anesthesiologists grade, and medical comorbidities. Propensity scores represented the conditional probabilities for each patient having a femoral neck fracture based on their individual characteristics, excluding their actual fracture status. Outcomes of interest included operative time, length of stay (LOS), complications, transfusion, discharge destination, and readmission. There were 42,692 patients identified (41,739 OA; 953 femoral neck fractures) with 953 patients in each group for the matched analysis. RESULTS: For patients with fracture, operative times were slightly longer (98 versus 92 minutes, p = 0.015), they experienced longer LOS (6 versus 4 days, p < 0.001), and the overall frequency of complications was greater compared with patients with OA (16% versus 6%, p < 0.001). Although the frequency of preoperative transfusions was higher in the fracture group (2.0% versus 0.2%, p = 0.002), the frequency of postoperative transfusion was not different between groups (27% versus 24%, p = 0.157). Having a femoral neck fracture versus OA was strongly associated with any postoperative complication (odds ratio [OR], 2.8; 95% confidence interval [CI], 2.1-3.8]; p < 0.001), unplanned readmission (OR, 1.8; 95% CI, 1.0-3.2; p = 0.049), and discharge to an inpatient facility (OR, 1.7; 95% CI, 1.4-2.0; p < 0.001). CONCLUSIONS: Compared with THA for OA, THA for femoral neck fracture is associated with greater rates of complications, longer LOS, more likely discharge to continued inpatient care, and higher rates of unplanned readmission. This implies higher resource utilization for patients with a fracture. These differences exist despite matching of other preoperative risk factors. As healthcare reimbursement moves toward bundled payment models, it would seem important to differentiate patients and procedures based on the resource utilization they represent to healthcare systems. These results show different expected resource utilization in these two fundamentally different groups of patients undergoing hip arthroplasty, suggesting a need to modify healthcare policy to maintain access to THA for all patients. LEVEL OF EVIDENCE: Level III, therapeutic study.

Difficult conversations in orthopaedics.

There is an overall lack of training in the communication skills needed by physicians to effectively navigate challenging patient encounters. So-called difficult patients have specific obstructive behaviors that make it challenging to establish a successful doctor-patient partnership and can elicit strong negative emotions in the physician. Instead of labeling the patient as difficult, it is more useful to consider encounters as difficult events and rely on diagnostic and interventional techniques similar to those used in solving any other clinical problem. In difficult interactions, patients may have the perception that the physician is less technically skilled, they were allotted inadequate time, received poor explanations, and were overall dissatisfied with the visit. Physicians who experience difficult encounters may find it difficult to communicate with patients. The physician is often not attuned to the psychosocial aspects of patient care and is frustrated and uneasy with patients. To improve patient and physician satisfaction and healthcare outcomes, it is helpful to review the skills and strategies for delivering bad news, managing angry patients, addressing financial concerns, and dealing with drug-seeking patients.
