Facilitated Regional Collaboration and In-Hospital Surgical Complication

Surgical quality improvement efforts are challenging due to the multidisciplinary nature of care, difficulties obtaining reliable data, and variability in quality metrics. The objective of this analysis was to assess whether participation in a regional collaborative quality initiative was associated with decreased in-hospital surgical complication in South Carolina. In-hospital surgical complication rates were determined using a statewide all-payer claims data set. Retrospective, univariate, and longitudinal multivariable analyses were performed and adjustments were made to account for aggregated hospital-level patient characteristics. The analysis included 275,387 general surgery cases performed in South Carolina hospitals between January 2016 and December 2018. Eight hospitals involved in the South Carolina Surgical Quality Collaborative (SCSQC) performed 56,179 cases and 51 non-SCSQC hospitals performed 219,208 cases. Univariate analysis revealed SCSQC hospitals performed operations in older patients (p < 0.0001) and patients with higher mean Charlson Comorbidity Index scores (p < 0.0001). SCSQC hospitals had higher mean in-hospital surgical complication rates at the surgery level compared with non-SCSQC hospitals (8.3% vs 7.0%; p < 0.0001). However, in multivariable analyses, the rate ratio for in-hospital surgical complication in SCSQC hospitals was 0.994 (95% CI, 0.989 to 0.998; p= 0.008) per month compared with non-SCSQC hospitals. This suggests a 21.6% (95% CI, 7.2% to 39.6%) proportional decrease in the rate of in-hospital surgical complication during 3 years associated with participation in the regional collaborative quality initiative. Structured collaboration between facilities, reliable data abstraction support, timely data review, and active member participation resulted in outcomes improvements for participating hospitals compared with hospitals that did not participate in a regional collaborative quality initiative.

The Next Frontier of Outcomes Research: Collaborative Quality Initiatives.

Quality improvement efforts at the federal level have instituted both rewards and penalties as incentives to improve health care quality. However, neither of these methods has shown long-lasting improvements. Furthermore, many programs have focused on decreasing mortality or hospital readmissions, measurements that are not applicable to many surgical fields, including plastic surgery. One model that has been shown to be effective is a collaborative quality initiative that uses a pay-for-participation method whereby participants learn from one another and institute changes to improve patient care. Many of these changes are process measures that are easier to implement and quicker to show improvement than structural or outcome measures. Regional collaborative quality initiatives have been developed in other surgical specialties such as bariatric surgery and urology. Currently, the authors are establishing a new collaborative quality initiative for hand surgery: the Michigan Collaborative Hand Initiative for Quality in Surgery. It is a collaboration of nine sites with the goal of identifying areas that are in need of quality improvement in hand surgery and implementing measures to improve on them. The authors believe that collaborative quality initiatives will promote high-quality care and should be incorporated into the field of plastic surgery.

Summary of knee implant one, three, five, and 10-year revision risk reported by national and regional arthroplasty registries: a valuable source of evidence for clinical decision-making.

Optimal implant selection is a major component of high-quality arthroplasty care, and revision risk is an important parameter characterizing knee arthroplasty implant clinical performance.National and regional arthroplasty registries are essential sources of revision risk data, but these data are often difficult to find because they are buried within extensive annual reports. Summarizing total knee arthroplasty (TKA) implant revision risks as presented in registry reports can maximize the usefulness of registry data for orthopaedic surgeons.The findings summarize the revision risk data found in national arthroplasty reports from the Australian, Danish, Finnish, and the England, Wales, Northern Ireland and the Isle of Man registries, and in regional arthroplasty reports from the Emilia-Romagna Region (Italty), and the Michigan Arthroplasty Registry Collaborative Quality Initiative (MARCQI) registries.The six supplemental summary tables present revision risk data for TKA implants by cemented, uncemented, hybrid, and unreported fixation types. Additional summary tables are presented for revision risk of unicondylar (UKA) and patellofemoral joint (PFJ) revisions. Within TKA fixation categories, revision risks at 10 years ranged from 2.4% to 35.7% (cemented), 2.8% to 25.0% (uncemented), 2.0% to 9.2% (hybrid), and 0.0% to 39.7% (unreported). Unicondylar 10-year revision risk ranged from 4.9% to 17.2%. Patellofemoral joint 10-year revision risk ranged from 15.2% to 21.7%.There is substantial variation in one, three, five, and 10-year revision risk across implants, which suggests surgeons should choose implants carefully.Cite this article: EFORT Open Rev 2020;5:268-272.

Evaluation of the Medial Stabilized Knee Design Using Data From National Joint Registries and Current Literature

BackgroundVarious designs of total knee arthroplasty (TKA) have provided satisfactory outcomes for the treatment of knee osteoarthritis for many years. The aim of the study is to evaluate the success and failure rate of the medial stabilized (MS) TKA design through national joint registries and the current literature. Materials and MethodsA comprehensive literature review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses was carried out through PubMed and MEDLINE database. The international registries analyzed included the National Joint Registry, the Australian Orthopedic Association National Joint Replacement Registry, the Dutch Arthroplasty Register, the New Zealand Orthopedic Association Joint Registry, and the Michigan Arthroplasty Registry Collaborative Quality Initiative. We are reporting descriptive data which include means and percentages of survival rates and revision rates and number of years after the primary procedure. The revision rates and the cumulative revision rates are reported separately for each MS implant. ResultsOur detailed review identified 5 of 12 registries and 25 of 550 studies reporting on the survivorship of an MS TKA design. There were a total of 3684 procedures between the 25 studies, with an average survivorship free of aseptic loosening of 99% at 6.9 years. There are 26,693 (2.5%) MS TKAs in the current National Joint Registry with a mean cumulative revision rate of 2.63% at 5 years, 3.35% at 10 years, and 4.6% at 15 years. The Australian Orthopedic Association National Joint Replacement Registry provides survivorship data on 19,249 (2.9%) MS TKAs, with a mean cumulative revision rate of 3.34% at 5 years, 7.4% at 10 years, and 8.1% at 15 years. The Dutch Arthroplasty Register contains survivorship data on 1490 MS designs and a mean revision rate of these implants is 0.8% at 1 year, 5.95% at 5 years, and 9.8% at 10 years. The Evolution MP is the only implant reported in the Michigan Arthroplasty Registry Collaborative Quality Initiative and has a revision rate of 2.28% at 3 years. ConclusionThe MS TKA design has comparable results to traditional TKA designs across several joint registries and 25 studies in the literature.

Statewide Utilization of Multimodal Analgesia and Length of Stay After Colectomy

BackgroundBoth enhanced recovery and anesthesia literature recommend multimodal perioperative analgesia to hasten recovery, prevent adverse events, and reduce opioid use after surgery. However, adherence to, and outcomes of, these recommendations are unknown. We sought to characterize use of multimodal analgesia and its association with length of stay after colectomy. Materials and methodsWithin a statewide, 72-hospital collaborative quality initiative, we evaluated postoperative analgesia regimens among adult patients undergoing elective colectomy between 2012 and 2015. We used logistic regression to identify factors associated with the use of multimodal analgesia and performed multivariable linear regression to evaluate its association with postoperative length of stay (LOS). ResultsAmong 7265 patients who underwent elective colectomy in the study period, 4660 (64.1%) received multimodal analgesia, 2405 (33.1%) received opioids alone, and 200 (2.8%) received one nonopioid pain medication alone. Multimodal analgesia was independently associated with shorter adjusted postoperative LOS, compared with opioids alone (5.60 d [95% CI 5.38–5.81] versus 5.96 d [5.68-6.24], P = 0.016). ConclusionsMultimodal analgesia is associated with shorter LOS, yet one-third of patients statewide received opioids alone after colectomy. As surgeons increasingly focus on our role in the opioid crisis, particularly in postdischarge opioid prescribing, we must also focus on inpatient postoperative pain management to limit opioid exposure. At the hospital level, this may have the added benefit of decreasing LOS and hastening recovery.

Utilization of inhaled nitric oxide after surgical repair of truncus arteriosus: A multicenter analysis.

Elevated pulmonary vascular resistance (PVR) is common following repair of truncus arteriosus. Inhaled nitric oxide (iNO) is an effective yet costly therapy that is frequently implemented postoperatively to manage elevated PVR. We aimed to describe practice patterns of iNO use in a multicenter cohort of patients who underwent repair of truncus arteriosus, a lesion in which recovery is often complicated by elevated PVR. We also sought to identify patient and center factors that were more commonly associated with the use of iNO in the postoperative period. Retrospective cohort study. 15 tertiary care pediatric referral centers. All infants who underwent definitive repair of truncus arteriosus without aortic arch obstruction between 2009 and 2016. Descriptive statistics were used to demonstrate practice patterns of iNO use. Bivariate comparisons of characteristics of patients who did and did not receive iNO were performed, followed by multivariable mixed logistic regression analysis using backward elimination to identify independent predictors of iNO use. We reviewed 216 patients who met inclusion criteria, of which 102 (46%) received iNO in the postoperative period: 69 (68%) had iNO started in the operating room and 33 (32%) had iNO initiated in the ICU. Median duration of iNO use was 4 days (range: 1-21 days). In multivariable mixed logistic regression analysis, use of deep hypothermic circulatory arrest (odds ratio: 3.2; 95% confidence interval: 1.2, 8.4) and center (analyzed as a random effect, p=.02) were independently associated with iNO use. In this contemporary multicenter study, nearly half of patients who underwent repair of truncus arteriosus received iNO postoperatively. Use of iNO was more dependent on individual center practice rather than patient characteristics. The study suggests a need for collaborative quality initiatives to determine optimal criteria for utilization of this important but expensive therapy.

1955 Hysterectomy Complications Relative to Hemoglobin A1c

Study Objective To evaluate the risk of postoperative complications among diabetic and nondiabetic patients stratified by hemoglobin A1c (HbA1c). Design A statewide collaborative quality initiative database was queried to identify 41,286 hysterectomies performed at 63 hospitals from January 1, 2013 to April 30, 2018. A specialized clinical quality reviewer abstracted medical record data including Diabetes Mellitus (DM) diagnosis. DM was present when the condition was managed >2 weeks prior to surgery, and/orifHbA1c >6.5%. The preoperative HbA1c closest to and not more than 90 days before surgery was abstracted when available. Complications included acute renal failure, pneumonia, surgical site infection, cardiac dysfunction, VTE, sepsis, unplanned intubation, cardiac arrest, MI, and stroke. A sensitivity analysis identified thresholds of complications by DM diagnosis stratified by HbA1c. A mixed, multivariate logistic regression model was developed to identify independent associations between DM stratified by HbA1cand risk of complications adjusted for age, BMI >35, surgical approach, medical comorbidities, and clustering by hospital. Setting NA Patients or Participants NA Interventions NA Measurements and Main Results The sensitivity analysis identified four groups of risk for postoperative complications—1) no DM and no HbA1c; 2) no DM with HbA1c normal or increased to 6.5%; 3) DM and noHbA1c or HbA1c Conclusion Diabetes diagnosis and measurement of preoperative HbA1c each independently provide risk stratification for postoperative complications after hysterectomy, with the highest observed risk among diabetics with a preoperative HbA1c ≥9%.

Early Results of a Modern Uncemented Total Knee Arthroplasty System.

Historically, cementless total knees were associated with early failure, which made cemented total knee arthroplasty the gold standard. Manufacturers have introduced newer uncemented technologies that provide good initial stability and use highly porous substrates for bony in-growth. The authors hypothesized that the implants would have equivalent 90-day clinical and economic outcomes. Prospectively collected data on 252 uncemented knees in the Michigan Arthroplasty Registry Collaborative Quality Initiative database were reviewed. Ninety-day outcomes, demographics, length of stay, complications, emergency department visits, readmissions, and financial data were compared with those of an age-matched group of cemented knees. Uncemented knees had shorter length of stay (1.58 vs 1.87 days; P<.01), were more frequently discharged home (90.48% vs 68.75%; P<.0001), and used less home care (6.35% vs 19.14%; P<.0001) or extended care facilities (2.78% vs 11.72%; P=.0001). More uncemented knees had "no complications." Moreover, there were no re-operations in uncemented knees, compared with 19 reoperations in cemented knees. Uncemented knees were better than age-matched counterparts for Knee injury and Osteoarthritis Outcome Score (63.69 vs 47.10, n=85 and n=43, P<.0001) and Patient-Reported Outcomes Measurement Information System (PROMIS) T-Physical and T-Mental scores (44.12 vs 39.45, P<.0001; 51.84 vs 47.82, P=.0018). Cemented cases were more expensive overall, and surgical ($6806.43 vs $5710.78; P<.01) and total hospital ($8347.65 vs $7016.11; P<.01) costs were higher. The 90-day readmission and hospital outpatient costs were not significantly different between designs. Uncemented total knee arthroplasty, when using modern technologies, is successful and economically viable for an at-risk bundle. The results of this study should alleviate fears of increased cost, early failure, complications, or poor outcomes with the use of a modern uncemented total knee arthroplasty.

Long-Term Sustainability of a Quality Initiative Program on Transfusion Rates in Total Joint Arthroplasty: A Follow-Up Study

BackgroundThere are significant variations in transfusion rates among institutions performing total joint arthroplasty. We previously demonstrated that implementation of an educational program to increase awareness of the American Association of Blood Banks’ transfusion guidelines led to an immediate decrease in transfusion rates at our facilities. It remained unclear how this initiative would endure over time. We report the long-term success and sustainability of this quality program. MethodsWe reviewed the Michigan Arthroplasty Collaborative Quality Initiative data from 2012 through 2017 of all patients undergoing primary hip and knee arthroplasty at our institutions for preoperative and postoperative hemoglobin level, transfusion status, and number of units transfused and transfusions outside of protocol to identify changes surrounding our blood transfusion educational initiative. We calculated the transfusions prevented and cost implications over the course of the study. ResultsWe identified 6645 primary hip and knee arthroplasty patients. There was a significant decrease in transfusion rate and overall transfusions in each group when compared to pre-education values. Subgroup analysis of TKA and THA independently showed significant decreases in both transfusion rate and overall transfusions. Over the final 3 years of the study, only 2 patients were transfused outside of the American Association of Blood Banks protocol. We estimate prevention of 519 transfusions over the study period. ConclusionApplication of this quality initiative was an effective means of identifying opportunities for quality improvement. The program was easily initiated, had significant early impact, and has been shown to be sustainable.

Improving neonatal resuscitation in Tennessee: a large-scale, quality improvement project.

We report a statewide collaborative quality initiative to improve resuscitation and stabilization practices following introduction of the 6th edition of the Neonatal Resuscitation Program. Participants drafted a consensus toolkit of interventions and corresponding measures. Hospital teams collected baseline data, and implemented changes using PDSA-cycles and statistical process control charts. Nine Tennessee NICUs submitted data on 3771 resuscitations. "Special cause" improvements were achieved and sustained for pre-resuscitation checklists (77-90%) and team briefings (80-92%). Time to intravenous access (50-42 min), glucose infusion initiation (73-60 min), and antibiotic dosing (113-98 min) were also significantly reduced. Teams were unable to meet new NRP oxygen saturation targets. Improvements in post-resuscitation debriefing were not sustained, while communication with parents declined significantly (68-60%). Large-scale collaboration facilitated statewide implementation of new guidelines, while highlighting under-appreciated systems challenges among competing resource demands.

The Michigan Arthroplasty Registry Collaborative Quality Initiative Experience: Improving the Quality of Care in Michigan.

The Michigan Arthroplasty Registry Collaborative Quality Initiative (MARCQI) is a regional quality improvement effort that is focused on hip and knee arthroplasty. From its inception in 2012, MARCQI has grown to include data from 66 hospitals and surgery centers, and contains over 209,000 fully abstracted cases in its database. Using high-quality risk-standardized outcomes data, MARCQI drives quality improvement through a collaborative and nonpunitive structure. Quality improvement initiatives have included transfusion reduction, infection prevention, venous thromboembolism reduction, and reduction of discharge to nursing homes. In addition, MARCQI focuses on postmarket surveillance of implants by computing revision-risk estimates based on the cases that were registered prior to the end of 2016. This paper describes the impact of MARCQI on the quality of hip and knee arthroplasty care in the state of Michigan since its inception in 2012, and it briefly summarizes the recently released 5-year report.

Implementation of a regional structure across an oncology collaborative quality initiative and the impact on physician engagement.

149 Background: The Michigan Oncology Quality Consortium (MOQC) is a statewide collaborative quality initiative (CQI) sponsored by Blue Cross/Blue Shield of Michigan. The consortium uses Quality Oncology Practice Initiative (QOPI) measures to identify gaps in care and opportunities to improve quality. Data are collected on patients regardless of payer. MOQC includes nearly 90% of eligible medical oncologists (n = 364) in Michigan. We describe physician engagement within MOQC and quality improvement efforts after implementation of a regional structure in the CQI. Methods: The MOQC regional structure was introduced in Spring 2017. Forty-eight practices self-selected into 6 regions roughly by geographic location. Beginning in Spring 2017, a physician from each practice was required to attend both the Spring and Fall Regional Meetings and encouraged to bring an additional representative (e.g. administrative leader) from their practice. Regional meetings were facilitated by the MOQC Coordinating Center. Within each region, practices selected to work on one measure from a finite set of QOPI measures. and shared best practices gleaned from their quality improvement work, according to the Plan-Do-Study-Act cycle of quality improvement. We report on our primary outcome, the change in physician engagement, defined as attendance at biannual MOQC meetings (distinct from the Regional Meetings), before and after the introduction of the regional structure. Results: Provider engagement, measured by attendance at the biannual meetings increased from an average of 17.3 physicians in the 3 years before the introduction of the regional structure, to 33 physicians in the first meeting, and 22 physicians in the second meeting after the introduction of the regional structure. Conclusions: Implementation of a regional structure increased provider engagement, and provided a systematic approach to the launching of quality improvement efforts in an oncology CQI. Engaging providers at the regional level, which incorporates cultural aspects of geographically similar practices, may provide opportunities not otherwise recognized in larger consortia.

Association of Aspirin With Prevention of Venous Thromboembolism in Patients After Total Knee Arthroplasty Compared With Other Anticoagulants

There has been significant debate in the surgical and medical communities regarding the appropriateness of using aspirin alone for venous thromboembolism (VTE) prophylaxis following total knee arthroplasty (TKA). To determine the acceptability of aspirin alone vs anticoagulant prophylaxis for reducing the risk of postoperative VTE in patients undergoing TKA. Noninferiority study of a retrospective cohort of TKA cases submitted to the Michigan Arthroplasty Registry Collaborative Quality Initiative at 29 member hospitals, ranging from small community hospitals to large academic and nonacademic medical centers in Michigan. The study included 41 537 patients who underwent primary TKA between April 1, 2013, and October 31, 2015. Clinical events were monitored for 90 days after surgery. Data were analyzed between September and October 2016. The method of pharmacologic prophylaxis: neither aspirin nor anticoagulants for 668 patients (1.6%), aspirin only for 12 831 patients (30.9%), anticoagulant only (eg, low-molecular-weight heparin, warfarin, and Xa inhibitors) for 22 620 patients (54.5%), and both aspirin/anticoagulant for 5418 patients (13.0%). Most patients were also using intermittent pneumatic compression stockings. The primary composite outcome was the first occurrence of VTE or death. The noninferiority margin was specified as 0.3. The secondary outcome was bleeding events. Of the 41 537 patients, 14 966 were men (36%), and the mean age was 65.8 years. A VTE event occurred in 573 of 41 537 patients (1.38%); 32 of 668 (4.79%) who received no pharmacologic prophylaxis, 149 of 12 831 (1.16%) treated with aspirin alone, 321 of 22 620 (1.42%) with anticoagulation alone, and 71 of 5418 (1.31%) prescribed both aspirin and anticoagulation. Aspirin only was noninferior for the composite VTE outcome compared with those receiving other chemoprophylaxis (adjusted odds ratio, 0.85; 95% CI, 0.68-1.07, P for inferiority = .007). Bleeding occurred in 457 of 41 537 patients (1.10%), 10 of 668 (1.50%) without prophylaxis, 116 of 12 831 (0.90%) in the aspirin group, 258 of 22 620 (1.14%) with anticoagulation, and 73 of 5418 (1.35%) of those receiving both. Aspirin alone was also noninferior for bleeding complications (adjusted odds ratio, 0.80; 95% CI, 0.63-1.00, P for inferiority <.001). In this study of patients undergoing TKA, aspirin was not inferior to other anticoagulants in the postoperative rate of VTE or death. Aspirin alone may provide similar protection from postoperative VTE compared with other anticoagulation treatments.

Readmission Rates for One Versus Two-Midnight Length of Stay for Primary Total Knee Arthroplasty

The length of stay (LOS) in the hospital for total knee arthroplasty (TKA) has been declining over recent decades. The purpose of this study was to determine if patients with an LOS for TKA that includes only 1 midnight have an increased odds of 90-day readmission compared with those with a 2-midnight LOS. We also sought to identify any predictors of 90-day hospital readmission among those readmitted during our period of analysis. A retrospective review of the Michigan Arthroplasty Registry Collaborative Quality Initiative (MARCQI) database was performed to identify patients with a 1-midnight or 2-midnight LOS for TKA during a 5-year period. The primary end point of this study was inpatient readmission within the 90-day postoperative period. A multiple logistic regression model and propensity score matching were used to compare the odds of 90-day readmission between 1-midnight and 2-midnight LOS. The secondary end points of this study were 90-day complications. There were 96,250 TKA procedures identified in the database, and 46,709 met our inclusion criteria for LOS. No difference in 90-day-readmission odds between patients with a 1-midnight LOS and those with a 2-midnight LOS for primary TKA was identified. Male sex, single marital status, age of ≥80 years, type-I diabetes, previous smoking, narcotic use prior to surgery, and a higher American Society of Anesthesiologists (ASA) scores increased the odds of 90-day readmission. Patients in the age group of ≥50 to <65 years, those with a higher preoperative hemoglobin level, and those with a positive social history of alcohol use were found to have decreased odds of readmission. We found no association between the LOS for primary TKA (1 midnight compared with 2 midnights) and the 90-day readmission risk. Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Noncompliance with American College of Surgeons Committee on Trauma recommended criteria for full trauma team activation is associated with undertriage deaths.

The appropriate triage of acutely injured patients within a trauma system is associated with improved rates of mortality and optimal resource utilization. The American College of Surgeons Committee on Trauma (ACS-COT) put forward six minimum criteria (ACS-6) for full trauma team activation (TTA). We hypothesized that ACS-COT-verified trauma center compliance with these criteria is associated with low undertriage rates and improved overall mortality. Data from a state-wide collaborative quality initiative was used. We used data collected from 2014 through 2016 at 29 ACS verified Level I and II trauma centers. Inclusion criteria are: adult patients (≥16 years) and Injury Severity Score of 5 or less. Quantitative data existed to analyze four of the ACS-6 criteria (emergency department systolic blood pressure ≤ 90 mm Hg, respiratory compromise/intubation, central gunshot wound, and Glasgow Coma Scale score < 9). Patients were considered to be undertriaged if they had major trauma (Injury Severity Score > 15) and did not receive a full TTA. 51,792 patients were included in the study. Compliance with ACS-6 minimum criteria for full TTA varied from 51% to 82%. The presence of any ACS-6 criteria was associated with a high intervention rate and significant risk of mortality (odds ratio, 16.7; 95% confidence interval, 15.2-18.3; p < 0.001). Of the 1,004 deaths that were not a full activation, 433 (43%) were classified as undertriaged, and 301 (30%) had at least one ACS-6 criterion present. Undertriaged patients with any ACS-6 criteria were more likely to die than those who were not undertriaged (30% vs. 21%, p = 0.001). Glasgow Coma Scale score less than 9 and need for emergent intubation were the ACS-6 criteria most frequently associated with undertriage mortality. Compliance with ACS-COT minimum criteria for full TTA remains suboptimal and undertriage is associated with increased mortality. These data suggest that the most efficient quality improvement measure around triage should be ensuring compliance with the ACS-6 criteria. This study suggests that practice pattern modification to more strictly adhere to the minimum ACS-COT criteria for full TTA will save lives. Care management, level III.

Conversion of Robot-assisted Partial Nephrectomy to Radical Nephrectomy: A Prospective Multi-institutional Study

To assess the incidence and factors affecting conversion from robot-assisted partial nephrectomy (RAPN) to radical nephrectomy. Between November 2014 and February 2017, 501 patients underwent attempted RAPN by 22 surgeons at 14 centers in 9 countries within the Vattikuti Collaborative Quality Initiative database. Patients were permanently logged for RAPN prior to surgery and were analyzed on an intention-to-treat basis. Multivariable logistic regression with backward stepwise selection of variables was done to assess the factors associated with conversion to radical nephrectomy. Overall conversion rate was 25 of 501 (5%). Patients converted to radical nephrectomy were older (median age [interquartile range] 66.0 [61.0-74.0] vs 59.0 [50.0-68.0], P = .012), had higher body mass index (BMI) (median 32.8 [24.9-40.9] vs 27.8 [24.6-31.5] kg/m2, P = .031), higher age-adjusted Charlson comorbidity score (median 6.0 [4.0-7.0] vs 4.0 [3.0-5.0], P <.001), higher American Society of Anesthesiologists score (score ≥3; 13/25 (52.0%) vs 130/476 (27.3%), P = .021), Preoperative estimated glomerular filtration rate (P = .141), clinical tumor stage (P = .145), tumor location (P = .140), multifocality (P = .483), and RENAL (radius, exophytic/endophytic properties, nearness of tumor to the collecting system or sinus in millimeters, and anterior/posterior location relative to polar lines) nephrometry score (P = .125) were not significantly different between the groups. On multivariable analysis, independent predictors for conversion were BMI (odds ratio [95% confidence interval]; 1.070 [1.018-1.124]; P = .007) and Charlson score (odds ratio [95% confidence interval]; 1.459 [1.179-1.806]; P = .001). RAPN was associated with a low rate of conversion. Independent predictors of conversion were BMI and Charlson score. Tumor factors such as clinical stage, location, multifocality, or RENAL score were not associated with increased risk of conversion.

Quality Initiative Programs Can Decrease Total Joint Arthroplasty Transfusion Rates—A Multicenter Study Using the MARCQI Total Joint Registry Database

BackgroundThe Michigan Arthroplasty Registry Collaborative Quality Initiative (MARCQI) noted wide variability between member hospitals in blood transfusion rates after primary total hip and knee arthroplasty (THA and TKA). Blood transfusion has substantial risks and accepted recommendations exist to guide transfusion practices. MARCQI began an initiative to decrease unnecessary transfusions by identifying/reporting outliers, discussing conservative transfusion practices, and recommending transfusion guidelines. There was a later recommendation to consider intraoperative use of tranexamic acid. MethodsAll MARCQI-registered unilateral TKA and THA cases from the 28 member hospitals (pre-November 2013) were included. For 3 time periods (before November 13, 2013; November 13, 2013, to November 12, 2014; and after November 12, 2014), we calculated average risk and range of transfusion, transfusion with nadir hemoglobin >8 g/dL, mean length of stay, and 90-day risk of discharge to nursing home, readmission, deep infection, and emergency department visits. ResultsFor THA, risk and range of transfusion decreased over the 3 time periods: 12.6% (2.5%-36.2%), 7.6% (2.2%-23.8%), and 4.5% (0.7%-14.4%); for TKA, 6.3% (1.3%-15.6%), 3.1% (0%-12.5%), and 1.3% (0%-7.4%). Decreases were also noted for transfusion with a nadir hemoglobin >8 g/dL with a near elimination of “unnecessary” transfusions. There was no evidence of increase in length of stay, discharge to nursing home, readmission, deep infection, or emergency department visits. ConclusionA simple intervention can decrease unnecessary blood transfusions during and after elective primary unilateral THA or TKA. A collaborative registry can be used effectively to improve the quality of patient care and set a new benchmark for transfusion.
