Patient Attitudes Toward Resident and Fellow Participation in Orthopedic Surgery.

BACKGROUND: Residents' and fellows' participation in orthopedic surgery is a potential source of anxiety and concern for patients. The purpose of this study was to determine patients' attitudes toward trainee involvement in orthopedic surgery, surgeons as educators, and disclosure of trainee involvement. METHODS: Three hundred two consecutive patients with preoperative and postoperative appointments at three arthroplasty practices in academic medical centers were surveyed with an anonymous, self-administered questionnaire. The questionnaire was developed in consultation with an expert in survey design. RESULTS: Two hundred thirty-four patients completed the questionnaire (response rate 77.5%). Respondents were 60.5% female, 79.6% white, 66.5% privately insured, and 82.8% had at least some college education. About 65.9% of the respondents felt that surgeons who teach are better surgeons. Nearly all felt residents and fellows should perform surgeries as part of their education (94.1% and 95.3%, respectively). However, 39.7% of the respondents were not satisfactory with a second-year resident assisting in their own surgery. Patients dissatisfied with their most recent orthopedic surgery were more likely to respond that they did not want residents helping with their surgery. Respondents agreed that resident or fellow involvement in surgery should be disclosed (92.2% and 90.1%, respectively). CONCLUSIONS: Insured and educated patients in the United States overwhelmingly desire disclosure of trainee involvement in their surgery. To address the need for orthopedic training in the context of a patient population that is not fully comfortable with trainee involvement in their own surgery, an open discussion between patients and surgeons regarding trainees' roles may be the best course of action.

Time-driven Activity-based Costing More Accurately Reflects Costs in Arthroplasty Surgery.

BACKGROUND: Cost estimates derived from traditional hospital cost accounting systems have inherent limitations that restrict their usefulness for measuring process and quality improvement. Newer approaches such as time-driven activity-based costing (TDABC) may offer more precise estimates of true cost, but to our knowledge, the differences between this TDABC and more traditional approaches have not been explored systematically in arthroplasty surgery. QUESTIONS/PURPOSES: The purposes of this study were to compare the costs associated with (1) primary total hip arthroplasty (THA); (2) primary total knee arthroplasty (TKA); and (3) three surgeons performing these total joint arthroplasties (TJAs) as measured using TDABC versus traditional hospital accounting (TA). METHODS: Process maps were developed for each phase of care (preoperative, intraoperative, and postoperative) for patients undergoing primary TJA performed by one of three surgeons at a tertiary care medical center. Personnel costs for each phase of care were measured using TDABC based on fully loaded labor rates, including physician compensation. Costs associated with consumables (including implants) were calculated based on direct purchase price. Total costs for 677 primary TJAs were aggregated over 17 months (January 2012 to May 2013) and organized into cost categories (room and board, implant, operating room services, drugs, supplies, other services). Costs derived using TDABC, based on actual time and intensity of resources used, were compared with costs derived using TA techniques based on activity-based costing and indirect costs calculated as a percentage of direct costs from the hospital decision support system. RESULTS: Substantial differences between cost estimates using TDABC and TA were found for primary THA (USD 12,982 TDABC versus USD 23,915 TA), primary TKA (USD 13,661 TDABC versus USD 24,796 TA), and individually across all three surgeons for both (THA: TDABC = 49%-55% of TA total cost; TKA: TDABC = 53%-55% of TA total cost). Cost categories with the most variability between TA and TDABC estimates were operating room services and room and board. CONCLUSIONS: Traditional hospital cost accounting systems overestimate the costs associated with many surgical procedures, including primary TJA. TDABC provides a more accurate measure of true resource use associated with TJAs and can be used to identify high-cost/high-variability processes that can be targeted for process/quality improvement. LEVEL OF EVIDENCE: Level III, therapeutic study.

Higher Preoperative Patient Activation Associated With Better Patient-reported Outcomes After Total Joint Arthroplasty.

BACKGROUND: Despite widely reported success associated with hip and knee replacements, some patients remain dissatisfied with their outcomes. Patient activation, an individual's propensity to engage in adaptive health behaviors, has been measured as a potentially important factor contributing to health outcomes, cost, and patient experience of care. However, to our knowledge, it has not been studied in patients undergoing total joint arthroplasties (TJAs). QUESTIONS/PURPOSES: We wanted to determine whether patients with higher activation scores would experience (1) greater resolution of pain and improved activity, (2) greater improvements in postoperative physical and mental health, and (3) greater patient satisfaction after primary THA or TKA. METHODS: We approached 174 patients and enrolled 135 who were undergoing primary THA or TKA at one of two hospitals between January 2013 and May 2014. Patient Activation Measure (PAM) scores were obtained preoperatively and patient-reported outcomes were assessed and completed for 125 patients pre- and postoperatively at the 6- or 12-month visit. We assessed pain and activity with the Hip Disability and Osteoarthritis Outcome Score (HOOS), Knee Injury and Osteoarthritis Outcome Score (KOOS), and University of California Los Angeles (UCLA) activity scores. We measured physical and mental health by calculating SF12v2® scores and measured patient satisfaction with the Hip and Knee Satisfaction Scale (HKSS). Linear regression models were used to test the association between baseline PAM and postoperative patient-reported outcomes. RESULTS: Overall, patients with a higher baseline PAM score experienced better pain relief using the HOOS/KOOS pain scores (R2=0.311, p=0.048) and symptoms using the HOOS/KOOS symptom scores (R2=0.272, p=0.021). In addition, higher PAM scores were associated with better postoperative mental health using the SF12v2® (R2=0.057, p<0.001), but were not associated with higher physical health (R2=0.176, p=0.173). Finally, higher PAM scores were associated with having greater postoperative satisfaction after surgery using the HKSS questionnaire (R2=0.048, p=0.023). CONCLUSIONS: Higher preoperative patient activation was associated with better pain relief, decreased symptoms, improved mental health, and greater satisfaction after TJA. Future efforts should be aimed at studying if improving patient activation before surgery results in better patient-reported outcomes after elective THA or TKA. LEVEL OF EVIDENCE: Level II, prognostic study.

What factors influence the production of orthopaedic research in East Africa? A qualitative analysis of interviews.

BACKGROUND: Research addressing the burden of musculoskeletal disease in low- and middle-income countries does not reflect the magnitude of the epidemic in these countries as only 9% of the world's biomedical resources are devoted to addressing problems that affect the health of 90% of the world's population. Little is known regarding the barriers to and drivers of orthopaedic surgery research in such resource-poor settings, the knowledge of which would help direct specific interventions for increasing research capacity and help surgeons from high-income countries support the efforts of our colleagues in low- and middle-income countries. PURPOSE: We sought to identify through surveying academic orthopaedic surgeons in East Africa: (1) barriers impeding research, (2) factors that support or drive research, and (3) factors that were identified by some surgeons as barriers and others as drivers (what we term barrier-driver overlap) as they considered the production of clinical research in resource-poor environments. MATERIALS: Semistructured interviews were conducted with 21 orthopaedic surgeon faculty members at four academic medical centers in Ethiopia, Kenya, Tanzania, and Uganda. Qualitative content analysis of the interviews was conducted using methods based in grounded theory. Grounded theory begins with qualitative data, such as interview transcripts, and analyzes the data for repeated ideas or concepts which then are coded and grouped into categories which allow for identification of subjects or problems that may not have been apparent previously to the interviewer. RESULTS: We identified and quantified 19 barriers to and 21 drivers of orthopaedic surgery research (mentioned n = 1688 and n = 1729, respectively). Resource, research process, and institutional domains were identified to categorize the barriers (n = 7, n = 5, n = 7, respectively) and drivers (n = 7, n = 8, n = 6, respectively). Resource barriers (46%) were discussed more often by interview subjects compared with the research process (26%) and institutional barriers (28%). Drivers of research discussed at least once were proportionally similar across the three domains. Some themes such as research ethics boards, technology, and literature access occurred with similar frequency as barriers to and drivers of orthopaedic surgery research. CONCLUSIONS: The barriers we identified most often among East African academic orthopaedic faculty members focused on resources to accomplish research, followed by institutional barriers, and method or process barriers. Drivers to be fostered included a desire to effect change, collaboration with colleagues, and mentorship opportunities. The identified barriers and drivers of research in East Africa provide a targeted framework for interventions and collaborations with surgeons and organizations from high-resource settings looking to be involved in global health.

Impact of Smoking Cessation Counseling Prior to Total Joint Arthroplasty.

Perioperative smoking has been linked to surgical complications including poor wound healing, infection, myocardial infarction, prolonged length of stay, need for mechanical ventilation, and death. This study evaluated the effectiveness of preoperative counseling on smoking cessation for patients undergoing elective total joint arthroplasty. Thirty smokers with hip or knee osteoarthritis seeking hip or knee replacement surgery were enrolled prospectively. Interventions included counseling, referrals to smoking cessation programs including the California Smokers' Helpline and the Fontana Tobacco Treatment Program, nicotine replacement therapy (NRT), or instructing patients quit through the "cold turkey" method of abstinence. Patients were scheduled for surgery if they demonstrated abstinence from smoking, confirmed via expired carbon monoxide (CO) breath testing. Short- and long-term smoking cessation rates were evaluated. Thirty patients were enrolled; 21 patients (70%) passed the CO test, whereas 9 patients (30%) failed or did not follow up with a CO test. Thirteen of 21 patients (62%) quit using the "cold turkey" method, 5 of 21 patients (24%) quit using NRT, and 3 of 21 patients (14%) quit using outpatient treatment programs. Eighteen of 21 patients (86%) who quit smoking underwent surgery, and 14 patients had surgery within 6 months of smoking abstinence. Nine of the 14 patients (64%) remained smoke-free 6 months postoperatively confirmed through telephone questionnaire. These results suggest that elective surgery offers a strong incentive for patients to quit smoking, and surgeons can play a role offering a teachable moment and motivating this potentially life-altering behavioral change.

Current management of middle cerebral artery aneurysms: surgical results with a "clip first" policy.

BACKGROUND: One response to randomized trials like the International Subarachnoid Aneurysm Trial has been to adopt a "coil first" policy, whereby all aneurysms be considered for coiling, reserving surgery for unfavorable aneurysms or failed attempts. Surgical results with middle cerebral artery (MCA) aneurysms have been excellent, raising debate about the respective roles of surgical and endovascular therapy. OBJECTIVE: To review our experience with MCA aneurysms managed with microsurgery as the treatment of first choice. METHODS: Five hundred forty-three patients with 631 MCA aneurysms were managed with a "clip first" policy, with 115 patients (21.2%) referred from the Neurointerventional Radiology service and none referred from the Neurosurgical service for endovascular management. RESULTS: Two hundred eighty-two patients (51.9%) had ruptured aneurysms and 261 (48.1%) had unruptured aneurysms. MCA aneurysms were treated with clipping (88.6%), thrombectomy/clip reconstruction (6.2%), and bypass/aneurysm occlusion (3.3%). Complete aneurysm obliteration was achieved with 620 MCA aneurysms (98.3%); 89.7% of patients were improved or unchanged after therapy, with a mortality rate of 5.3% and a permanent morbidity rate of 4.6%. Good outcomes were observed in 92.0% of patients with unruptured and 70.2% with ruptured aneurysms. Worse outcomes were associated with rupture (P = .04), poor grade (P = .001), giant size (P = .03), and hemicraniectomy (P < .001). CONCLUSION: At present, surgery should remain the treatment of choice for MCA aneurysms. Surgical morbidity was low, and poor outcomes were due to an inclusive policy that aggressively managed poor-grade patients and complex aneurysms. This experience sets a benchmark that endovascular results should match before considering endovascular therapy an alternative for MCA aneurysms.
