Impact of Clinical Decision Support with Mandatory versus Voluntary Venous Thromboembolism Risk Assessment in Hospitalized Patients.

Background Venous thromboembolism (VTE) causes significant preventable morbidity and mortality in hospitalized patients. Assessing VTE risk is essential to initiating appropriate prophylaxis and reducing VTE outcomes. Studies show that computerized clinical decision support (CDS) can improve VTE risk assessment (RA), prophylaxis, and outcomes but few examined the effectiveness of specific design features. From 2008 to 2016, University of Michigan Health implemented CDS for VTE prevention in four stages, which alternated between voluntary and mandatory RA using the 2005 Caprini model and generated inpatient orders for risk-appropriate prophylaxis based on CHEST guidelines. This cross-sectional study evaluated the impact of mandatory versus voluntary RA on VTE prophylaxis and outcomes for adult medical and surgical patients admitted to the health system. Methods Interrupted time series analysis was conducted to evaluate the trend in smart order set-recommended VTE prophylaxis by CDS stage. Logistic regression with CDS stage as the primary independent variable was used in pairwise comparisons of VTE during hospitalization and within 90 days post-discharge for mandatory versus voluntary RA. Adjusted odd ratios (ORs) were calculated for total, in-hospital, and post-discharge VTE. Results In this study of 223,405 inpatients over 8 years, smart order set-recommended prophylaxis increased from 65 to 79%; it increased significantly when voluntary RA in Stage 1 became mandatory in Stage 2 (10.59%, p < 0.001) and decreased significantly when it returned to voluntary in Stage 3 (-11.24%, p < 0.001). The rate increased slightly when mandatory RA was reestablished in Stage 4 (0.23%, p = 0.935). Adjusted ORs for VTE were lower for mandatory RA versus adjacent stages with voluntary RA. The adjusted OR for Stage 2 versus Stage 1 was 14% lower ( p < 0.05) and versus Stage 3 was 11% lower ( p < 0.05). The adjusted OR for Stage 4 versus Stage 3 was 4% lower ( p = 0.60). These results were driven by changes in in-hospital VTE. By contrast, the incidence of post-discharge VTE increased in each successive stage. Conclusion Mandatory RA was more effective in improving smart order set-recommended prophylaxis and VTE outcomes, particularly in-hospital VTE. Post-discharge VTE increased despite high adherence to risk-appropriate prophylaxis, indicating that guidelines for extended, post-discharge prophylaxis are needed to further reduce VTE for hospitalized patients.

What are the features of high-performing quality improvement collaboratives? A qualitative case study of a state-wide collaboratives programme.

OBJECTIVES: Despite their widespread use, the evidence base for the effectiveness of quality improvement collaboratives remains mixed. Lack of clarity about 'what good looks like' in collaboratives remains a persistent problem. We aimed to identify the distinctive features of a state-wide collaboratives programme that has demonstrated sustained improvements in quality of care in a range of clinical specialties over a long period. DESIGN: Qualitative case study involving interviews with purposively sampled participants, observations and analysis of documents. SETTING: The Michigan Collaborative Quality Initiatives programme. PARTICIPANTS: 38 participants, including clinicians and managers from 10 collaboratives, and staff from the University of Michigan and Blue Cross Blue Shield of Michigan. RESULTS: We identified five features that characterised success in the collaboratives programme: learning from positive deviance; high-quality coordination; high-quality measurement and comparative performance feedback; careful use of motivational levers; and mobilising professional leadership and building community. Rigorous measurement, securing professional leadership and engagement, cultivating a collaborative culture, creating accountability for quality, and relieving participating sites of unnecessary burdens associated with programme participation were all important to high performance. CONCLUSIONS: Our findings offer valuable learning for optimising collaboration-based approaches to improvement in healthcare, with implications for the design, structure and resourcing of quality improvement collaboratives. These findings are likely to be useful to clinicians, managers, policy-makers and health system leaders engaged in multiorganisational approaches to improving quality and safety.

Correlation of Colorectal Surgical Skill With Patient Outcomes: A Cautionary Tale.

BACKGROUND: Previous work has demonstrated a correlation between video ratings of surgical skill and clinical outcomes. Some have proposed the use of video review for technical skill assessment, credentialing, and quality improvement. OBJECTIVE: Before its adoption as a quality measure for colorectal surgeons, we must first determine whether video-based skill assessments can predict patient outcomes among specialty surgeons. DESIGN: Twenty-one surgeons submitted one representative video of a minimally invasive colectomy. Each video was edited to highlight key steps and then rated by 10 peer surgeons using a validated American Society of Colon and Rectal Surgeons assessment tool. Linking surgeons' ratings to a validated surgical outcomes registry, we assessed the relationship between skill and risk-adjusted complication rates. SETTINGS: The study was conducted with the Michigan Surgical Quality Collaborative, a statewide collaborative including 70 community, academic, and tertiary hospitals. PATIENTS: Patients included those who underwent minimally invasive colorectal resection performed by the participating surgeons. MAIN OUTCOME MEASURES: Main outcome measures included 30-day risk-adjusted postoperative complications. RESULTS: The average technical skill rating for each surgeon ranged from 2.6 to 4.6. Risk-adjusted complication rate per surgeon ranged from 9.9% to 33.1%. Patients of surgeons in the bottom quartile of overall skill ratings were older and more likely to have hypertension or to smoke; patients of surgeons in the top quartile were more likely to be immunosuppressed or have an ASA score of 3 or higher. After patient- and surgery-specific risk adjustment, there was no statistically significant difference in complication rates between the bottom and top quartile surgeons (17.5% vs 16.8%, respectively, p = 0.41). LIMITATIONS: Limitations included retrospective cohort design with short-term follow-up of sampled cases. Videos were edited to highlight key steps, and reviewers did not undergo training to establish norms. CONCLUSIONS: Our study demonstrates that video-based peer rating of minimally invasive colectomy was not correlated with postoperative complications among specialty surgeons. As such, the adoption of video review for use in credentialing should be approached with caution.

Algunos autores han propuesto el uso de la revisión de videos para la evaluación de la habilidad técnica, la acreditación y la mejoría en la calidad quirúrgica.OBJETIVO:Antes de su adopción como medida de calidad entre los cirujanos colorrectales, primero debemos determinar si las evaluaciones de habilidades basadas en video pueden predecir los resultados clínicos de los pacientes entre cirujanos especializados.DISEÑO:Veintiún cirujanos enviaron un video representativo de una colectomía mínimamente invasiva. Cada video fue editado para resaltar los pasos clave y luego fué calificado por 10 cirujanos revisores utilizando una herramienta de evaluación validada por la ASCRS. Al vincular las calificaciones de los cirujanos al registro de resultados quirúrgicos aprobado, evaluamos la relación entre la habilidad y las tasas de complicaciones ajustadas al riesgo.AJUSTE:Colaboración en todo el estado incluyendo 70 hospitales comunitarios, académicos y terciarios, el Michigan Surgical Quality Collaborative.PACIENTES:Todos aquellos sometidos a resección colorrectal mínimamente invasiva realizada por los cirujanos participantes.MEDIDA DE RESULTADO PRINCIPAL:Complicaciones posoperatorias ajustadas al riesgo a los 30 días.RESULTADOS:La calificación de la habilidad técnica promedio de cada cirujano osciló entre 2.6 y 4.6. La tasa de complicaciones ajustada al riesgo por cirujano osciló entre el 9,9% y el 33,1%. Los pacientes operados por los cirujanos del cuartil inferior de las calificaciones generales de habilidades eran fumadores y añosos, y tambiés más propensos a la hipertensión arterial. Los pacientes operados por los cirujanos del cuartil superior tenían más probabilidades de ser inmunosuprimidos o tener una puntuación ASA> = 3. Después del ajuste de riesgo específico de la cirugía y el paciente, no hubo diferencias estadísticamente significativas en las tasas de complicaciones entre los cirujanos del cuartil inferior y superior (17,5% frente a 16,8%, respectivamente, p = 0,41).LIMITACIONES:Diseño de cohortes retrospectivo con seguimiento a corto plazo de los casos muestreados. Los videos se editaron para resaltar los pasos clave y los revisores no recibieron capacitación para establecer normas.CONCLUSIONES:Nuestro estudio demuestra que la evaluación realizada por los revisores basada en el video de la colectomía mínimamente invasiva no se correlacionó con las complicaciones post-operatorias entre los cirujanos especialistas. Por tanto, la adopción de la revisión del video quirúrgico para su uso en la acreditación profesional, debe abordarse con mucha precaución. Consulte Video Resumen en http://links.lww.com/DCR/B802.

Achieving the High-Value Colectomy: Preventing Complications or Improving Efficiency.

BACKGROUND: There is increased focus on the value of surgical care. Postoperative complications decrease value, but it is unknown whether high-value hospitals spend less than low-value hospitals in cases without complications. Previous studies have not evaluated both expenditures and validated outcomes in the same patients, limiting the understanding of interactions between clinical performance, efficient utilization of services, and costliness of surgical episodes. OBJECTIVE: This study aimed to identify payment differences between low- and high-value hospitals in colectomy cases without adverse outcomes using a linked data set of multipayer claims and validated clinical outcomes. DESIGN: This is a retrospective observational cohort study. We assigned each hospital a value score (ratio of cases without adverse outcome to mean episode payment). We stratified hospitals into tertiles by value and used analysis of variance tests to compare payments between low- and high-value hospitals, first for all cases, and then cases without adverse outcome. SETTING: January 2012 to December 2016, this investigation used clinical registry data from 56 hospitals participating in the Michigan Surgical Quality Collaborative, linked with 30-day episode payments from the Michigan Value Collaborative. PATIENTS: A total of 2947 patients undergoing elective colectomy were selected. MAIN OUTCOME MEASURES: The primary outcome measured was risk-adjusted, price-standardized 30-day episode payments. RESULTS: The mean adjusted complication rate was 31% (±10.7%) at low-value hospitals and 14% (±4.6%) at high-value hospitals (p < 0.001). Low-value hospitals were paid $3807 (17%) more than high-value hospitals ($22,271 vs $18,464, p < 0.001). Among cases without adverse outcome, payments were still $2257 (11%) higher in low-value hospitals ($19,424 vs $17,167, p = 0.04). LIMITATIONS: This study focused on outcomes and did not consider processes of care as drivers of value. CONCLUSIONS: In elective colectomy, high-value hospitals achieve lower episode payments than low-value hospitals for cases without adverse outcome, indicating mechanisms for increasing value beyond reducing complications. Worthwhile targets to optimize value in elective colectomy may include enhanced recovery protocols or other interventions that increase efficiency in all phases of care.

LOGRANDO LA COLECTOMÍA DE ALTO VALOR: PREVINIENDO COMPLICACIONES O MEJORANDO LA EFICIENCIA: Hay un mayor enfoque en el valor de la atención quirúrgica. Las complicaciones postoperatorias disminuyen el valor, pero se desconoce si en los casos sin complicaciones, los hospitales de alto valor gastan menos que los hospitales de bajo valor. Estudios anteriores no han evaluado ambos gastos y validado resultados en los mismos pacientes, limitando la comprensión de las interacciones entre el rendimiento clínico, utilización eficiente de los servicios y costos de los episodios quirúrgicos.Identificar las diferencias de pago entre los hospitales de alto y bajo valor, en casos de colectomía sin resultados adversos, utilizando un conjunto de datos vinculados de reclamos de pago múltiple y resultados clínicos validados.Estudio de cohorte observacional retrospectivo. Asignamos a cada hospital una puntuación de valor (proporción de casos sin resultado adverso al pago medio del episodio). Estratificamos los hospitales por valor en terciles y utilizamos el análisis de pruebas de varianza para comparar los pagos entre hospitales de bajo y alto valor, primero para todos los casos y luego casos sin resultados adversos.De enero del 2012 a diciembre del 2016, utilizando datos de registro clínico de 56 hospitales que participan en el Michigan Surgical Quality Collaborative, vinculado con pagos de episodios de 30 días, del Michigan Value Collaborative.Un total de 2947 pacientes con colectomía electiva.Pagos por episodio de 30 días, ajustados al riesgo y estandarizados por precio.La tasa media de complicación ajustada fue de 31% (±10.7%) en hospitales de bajo valor y 14% (±4.6%) en hospitales de alto valor (p < 0.001). A los hospitales de bajo valor se les pagó $3807 (17%) más que a los hospitales de alto valor ($22,271 frente a $18,464, p < 0.001). Entre los casos sin resultados adversos, los pagos fueron de $2257 (11%) más altos en hospitales de bajo valor ($19,424 vs $17,167, p = 0.04).Este estudio se centró en los resultados y no se consideraron a los procesos de atención, como impulsores de valor.En la colectomía electiva, los hospitales de alto valor logran pagos de episodios más bajos, que en los hospitales de bajo valor con casos sin resultados adversos, indicando mecanismos para aumentar el valor, más allá que la reducción de complicaciones. Objetivos valiosos para optimizar el valor de la colectomía electiva, pueden incluir mejoras en los protocolos de recuperación, así como otras intervenciones que aumenten la eficiencia en todas las fases de la atención.

Uptake of Total Mesorectal Excision and Total Mesorectal Excision Grading for Rectal Cancer: A Statewide Study.

BACKGROUND: Total mesorectal excision is associated with decreased local recurrence and improved disease-free survival following rectal cancer resection. The extent to which total mesorectal excision has been adopted in the United States is unknown. OBJECTIVE: We sought to assess trends in total mesorectal excision performance and grading in Michigan hospitals. DESIGN: This is a retrospective cohort study from the Michigan Surgical Quality Collaborative. Trends in total mesorectal excision performance and grade assignment were analyzed by using χ tests and linear regression. SETTINGS: Participating hospitals (initially 14 hospitals, now 38) abstracted medical records data for rectal cancer cases from 2007 to 2016. PATIENTS: Patients who underwent rectal cancer resection were included. MAIN OUTCOME MEASURE: The main outcome measures were surgeon-documented total mesorectal excision performance and pathologist-reported total mesorectal excision grade. RESULTS: Of 510 rectal cancer cases, 367 (72.0%) had surgeon-reported total mesorectal excision performance and 78 (15.3%) had pathologist-reported total mesorectal excision grade. Between-hospital variability in total mesorectal excision performance ranged from 0% to 97% and total mesorectal excision grading ranged from 0% to 90%. Total mesorectal excision grading was associated with a higher likelihood of also having adequate lymph node assessment (88.5% versus 71.9%, p = 0.002). There has been a statistically significant trend toward an increase in total mesorectal excision grading in the original 14 hospitals (p = 0.001), but not in the complete cohort of all hospitals (p = 0.057). LIMITATIONS: This is a retrospective cohort design with sampled rectal cancer cases. In addition, there is insufficient granularity to capture all factors associated with total mesorectal excision performance or grade assignment. CONCLUSIONS: The rates of total mesorectal excision performance and grade assignment are widely variable throughout the state of Michigan. Overall, grade assignment remains very low. This suggests an opportunity for quality improvement projects to increase total mesorectal excision performance and grading, involving both the surgeons and pathologists for effective implementation.

IMPLEMENTACIÓN DE LA ESCISIÓN MESORRECTAL TOTAL Y LA CLASIFICACIÓN POR ESCISIÓN MESORRECTAL TOTAL PARA EL CÁNCER RECTAL: UN ESTUDIO A NIVEL ESTATAL.: La escisión mesorrectal total se asocia con una menor recurrencia local y una mejor supervivencia libre de enfermedad después de la resección del cáncer rectal. Se desconoce hasta que punto se ha adoptado la escisión mesorrectal total en los Estados Unidos.Se intento evaluar las tendencias en el rendimiento y la clasificación de la escisión mesorrectal total en los hospitales de Michigan.Este es un estudio de cohorte retrospectivo de la "Michigan Surgical Quality Collaborative". Las tendencias en el rendimiento de la escisión mesorrectal total y la asignación de grado se analizaron mediante pruebas de chi-cuadrada y regresión lineal.Los hospitales participantes (inicialmente 14 hospitales, ahora 38) extrajeron datos de registros médicos de los casos de cáncer rectal desde 2007 hasta 2016.Pacientes que se sometieron a resección de cáncer rectal.Las principales medidas de resultado fueron el rendimiento de la escisión mesorrectal total documentado por el cirujano y el grado de escisión mesorrectal total informada por el patólogo.De 510 casos de cáncer rectal, 367 (72.0%) tenían un rendimiento de escisión mesorrectal total reportado por el cirujano y 78 (15.3%) tenían un grado de escisión mesorrectal total reportado por el patólogo. La variabilidad entre hospitales en el rendimiento de la escisión mesorrectal total varió del 0 al 97% y la clasificación de la escisión mesorrectal total varió del 0 al 90%. La clasificación de la escisión mesorrectal total se asoció con una mayor probabilidad de tener también una evaluación adecuada de los ganglios linfáticos (88.5% versus 71.9%, p = 0.002). Ha habido una tendencia estadísticamente significativa hacia un aumento en la clasificación de la escisión mesorrectal total en los 14 hospitales originales (p = 0.001), pero no en la cohorte completa de todos los hospitales (p = 0.057).Diseño de cohorte retrospectivo con casos de cáncer rectal muestreados. Además, no hay suficiente granularidad para capturar todos los factores asociados con el rendimiento de la escisión mesorrectal total o la asignación de grados.Las tasas de rendimiento de escisión mesorrectal total y asignación de grado son muy variables en todo el estado de Michigan. En general, la asignación de calificaciones sigue siendo muy baja. Esto sugiere una oportunidad para que los proyectos de mejora de la calidad aumenten el rendimiento y la clasificación de la escisión mesorrectal total, involucrando tanto a los cirujanos como a los patólogos para una implementación efectiva.

ß-Lactam vs Non-ß-Lactam Antibiotics and Surgical Site Infection in Colectomy Patients.

BACKGROUND: Surgical site infections (SSIs) represent a significant preventable source of morbidity, mortality, and cost. Prophylactic antibiotics have been shown to decrease SSI rates, and ß-lactam antibiotics are recommended by national guidelines. It is currently unclear whether recommended ß-lactam and recommended non-ß-lactam antibiotic regimens are equivalent with respect to SSI risk reduction in colectomy patients. STUDY DESIGN: We conducted a retrospective cohort study of SSI rates between prophylactic intravenously administered recommended ß-lactam and non-ß-lactam in colectomy patients (25 CPT codes) collected by the Michigan Surgical Quality Collaborative from January 2013 to February 2018. Surgical site infection rates were compared as a dichotomous variable (no SSI vs SSI). Mixed-effects regression was used to compare the association between receiving a ß-lactam or non-ß-lactam antibiotic and likelihood of having an SSI. RESULTS: Of 9,949 patients, 9,411 (94.6%) received ß-lactam antibiotics and 538 (5.4%) received non-ß-lactam antibiotics. Overall, there were 622 (6.3%) patients with SSIs. Of the patients receiving ß-lactam antibiotics, SSIs developed in 571 (6.1%) compared with 51 (9.5%) patients in the non-ß-lactam group. After applying mixed-effects logistic regression, prophylactic treatment with a non-ß-lactam regimen was associated with significantly higher odds of surgical site infection (odds ratio 1.65; 95% CI 1.20 to 2.26; p < 0.01). CONCLUSIONS: Colectomy patients receiving ß-lactam antibiotics had a lower likelihood of SSI compared with those receiving non-ß-lactam antibiotics, even when antibiotics were compliant with national recommendations. Our findings suggest that surgeons should prescribe ß-lactam antibiotics for prophylaxis whenever possible, reserving alternatives for those rare patients with true allergies or clinical indications for non-ß-lactam antibiotic prophylaxis.

Mechanisms of age and race differences in receiving minimally invasive inguinal hernia repair.

BACKGROUND: Black patients and older adults are less likely to receive minimally invasive hernia repair. These differences by race and age may be influenced by surgeon-specific utilization rate of minimally invasive repair. In this study, we explored the association between race, age, and surgeon utilization of minimally invasive surgery (MIS) with the likelihood of receiving MIS inguinal hernia repair. METHODS: A retrospective cohort study was performed in patients undergoing elective primary inguinal hernia repair from 2012 to 2016, using data from the Michigan Surgical Quality Collaborative, a 72-hospital clinical registry. Surgeons were stratified by proportion of MIS performed. Using hierarchical logistic regression models, we investigated the association between receiving MIS repair and race, age, and surgeon MIS utilization rate. RESULTS: Out of 4667 patients, 1253 (27%) received MIS repair. Out of 190 surgeons, 81 (43%) performed only open repair. Controlling for surgeon MIS utilization, race was not associated with MIS receipt (OR 0.93, p = 0.775), but older patients were less likely to receive MIS repair (OR 0.41, p < 0.001). CONCLUSIONS: Race differences were explained by surgeon MIS utilization, implicating access to MIS-performing surgeon as a mediator. Conversely, age disparity was independent of MIS utilization, even after adjusting for comorbidities, indicating some degree of provider bias against performing MIS repair in older patients. Interventions to address disparities should include systematic efforts to improve access, as well as provider and patient education for older adults.

Targeting Value-Driven Quality Improvement for Laparoscopic Cholecystectomy in Michigan.

OBJECTIVE: The purpose of this study was to evaluate complete episode expenditures for laparoscopic cholecystectomy, a common and lower-risk operation, to characterize novel targets for value-based quality improvement. SUMMARY BACKGROUND DATA: Despite enthusiasm for improving the overall value of surgical care, most efforts have focused on high-risk inpatient surgery. METHODS: We identified 19,213 patients undergoing elective laparoscopic cholecystectomy from 2012 to 2015 using data from Medicare and a large private payer. We calculated price-standardized payments for the entire surgical episode of care and stratified patients by surgeon. We used linear regression to risk- and reliability-adjusted expenditures for patient characteristics, diagnoses, and the use of additional procedures. RESULTS: Fully adjusted total episode costs varied 2.4-fold across surgeons ($7922-$17,500). After grouping surgeons by adjusted total episode payments, each component of the total episode was more expensive for patients treated by the most expensive versus the least expensive quartile of surgeons. For example, payments for physician services were higher for the most expensive surgeons [$1932, 95% confidence interval (CI) $1844-$2021] compared to least expensive surgeons ($1592, 95% CI $1450-$1701, P < 0.01). Overall differences were driven by higher rates of complications (10% vs. 5%) and readmissions (14% vs. 8%), and lower rates of ambulatory procedures (77% vs. 56%) for surgeons with the highest versus lowest expenditures. Projections showed that a 10% increase ambulatory operations would yield $3.6 million in annual savings for beneficiaries. CONCLUSIONS: Episode payments for laparoscopic cholecystectomy vary widely across surgeons. Although improvements in several domains would reduce expenditures, efforts to expand ambulatory surgical practices may result in the largest savings to beneficiaries in Michigan.

Association Between Hospital Staffing Models and Failure to Rescue.

OBJECTIVE: To identify hospital staffing models associated with failure to rescue (FTR) rates at low- and high-performing hospitals. BACKGROUND: FTR is an important quality measure in surgical safety and is a metric that hospitals are seeking to improve. Specific unit-level determinants of FTR, however, remain unknown. METHODS: Retrospective, observational study using data from the Michigan Quality Surgical Collaborative, which is a prospectively collected and clinically audited database in the state of Michigan. We identified 44,567 patients undergoing major general or vascular surgery from 2008 to 2012. Our main outcome measures were mortality, complications, and FTR rates. RESULTS: Hospital rates of FTR across low, middle, and high tertiles were 8.9%, 16.5%, and 19.9%, respectively (P < 0.001). Low FTR hospitals tended to have a closed intensive care unit staffing model (56% vs 20%, P < 0.001) and a higher proportion of board-certified intensivists (88% vs 60%, P < 0.001) when compared to high FTR hospitals. There was also significantly more staffing of low FTR hospitals by hospitalists (85% vs 20%, P < 0.001) and residents (62% vs 40%, P < 0.01). Low FTR hospitals were noted to have more overnight coverage (75% vs 45%, P < 0.001) as well as a dedicated rapid response team (90% vs 60%, P < 0.001). CONCLUSIONS: Low FTR hospitals had significantly more staffing resources than high FTR hospitals. Although hiring additional staff may be beneficial, there remain significant financial limitations for many hospitals to implement robust staffing models. Thus, our ongoing work seeks to improve rescue and implement effective staffing strategies within these constraints.

Surgeon utilization of minimally invasive techniques for inguinal hernia repair: a population-based study.

BACKGROUND: MIS utilization for inguinal hernia repair is low compared to in other procedures. The impact of low adoption in surgeons is unclear, but may affect regional access to minimally invasive surgery (MIS). We explored the impact of surgeon MIS utilization in inguinal hernia repair across a statewide population. METHODS: We analyzed 6723 patients undergoing elective inguinal hernia repair from 2012 to 2016 in the Michigan Surgical Quality Collaborative. The primary outcome was surgeon MIS utilization. The geographic distribution of high MIS-utilizing surgeons was compared across Hospital Referral Regions using Pearson's Chi-squared test. Hierarchical logistic regression was used to identify patient and hospital factors associated with MIS utilization. RESULTS: Surgeon MIS utilization varied, with 58% of 540 surgeons performing no MIS repair. For the remaining surgeons, MIS utilization was bimodally distributed. High-utilization surgeons were unevenly distributed across region, with corresponding differences in regional MIS rate ranging from 10 to 48% (p < 0.001). MIS was used in 41% of bilateral and 38% of recurrent hernia. MIS repair was more likely with higher hospital volume and less likely for patients aged 65+ (OR 0.68, p = 0.003), black patients (OR 0.75, p = 0.045), patients with COPD (OR 0.57, p < 0.001), and patients in ASA class > 3 (OR 0.79 p < 0.001). CONCLUSIONS: MIS utilization varies between surgeons, likely driving differences in regional MIS rates and leading to guideline-discordant care for patients with bilateral or recurrent hernia. Interventions to reduce this practice gap could include training programs in MIS repair, or regionalization of care to improve MIS access.

Understanding Disparities in Surgical Outcomes for Medicaid Beneficiaries.

BACKGROUND: Few studies have evaluated whether outcome disparities between Medicaid and private insurance beneficiaries are driven by the hospital at which the patient receives care. The purpose of this study was to evaluate the effect of the hospital on surgical outcomes in Medicaid beneficiaries. METHODS: We identified 139,566 non-elderly Medicaid and private insurance beneficiaries undergoing general, vascular, or gynecological surgery between 2012 and 2017 using a statewide clinical registry in Michigan. We calculated risk-adjusted rates of complications, readmissions, emergency department (ED) visits, and post-acute care utilization using multivariable logistic regression, accounting for patient and procedural factors. We then evaluated whether, and to what extent, the hospital influenced outcome disparities between Medicaid and privately insured beneficiaries. RESULTS: Risk-adjusted rates for all outcomes were higher in Medicaid beneficiaries. For example, overall post-discharge ED visit rates were 14.3% (95% CI 13.7% to 14.9%) for Medicaid compared to 7.5% (95% CI 7.1% to 7.9%, P < 0.01) for private insurance beneficiaries. Hospital factors explained 3.9% of the observed difference in complication rates between Medicaid and private insurance beneficiaries. In contrast, hospital factors explained a greater proportion of the disparities in readmissions (30.6%), ED visits (33.0%), and post-acute care utilization (16.1%). Results were similar when restricting the study population to elective cases only. CONCLUSIONS: Hospital factors account for a significant proportion of the disparities in post-discharge resource utilization between Medicaid and private insurance beneficiaries. Policies aiming to improve the quality and equity of surgical care for Medicaid beneficiaries should focus on the post-discharge period.

A Regional and National Database Comparison of Colorectal Outcomes.

BACKGROUND AND OBJECTIVES: The traditional open approach is still a common option for colectomy and the most common option chosen for rectal resections for cancer. Randomized trials and large database studies have reported the merits of the minimally invasive approach, while studies comparing laparoscopic and robotic options have reported inconsistent results. METHODS: This study was designed to compare open, laparoscopic, and robotic colorectal surgery outcomes in protocol-driven regional and national databases. Logistic and multiple linear regression analyses were used to compare standard 30-day colorectal outcomes in the Michigan Surgical Quality Collaborative (MSQC) and American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) databases. The primary outcome was overall complications. RESULTS: A total of 10,054 MSQC patients (open 37.5%, laparoscopic 48.8%, and robotic 13.6%) and 80,535 ACS-NSQIP patients (open 25.0%, laparoscopic 67.1%, and robotic 7.9%) met inclusion criteria. Overall complications and surgical site infections were significantly favorable for the laparoscopic and robotic approaches compared with the open approach. Anastomotic leaks were significantly fewer for the laparoscopic and robotic approaches compared with the open approach in ACS-NSQIP, while there was no significant difference between robotic and open approaches in MSQC. Laparoscopic complications were significantly less than robotic complications in MSQC but significantly more in ACS-NSQIP. Laparoscopic 30-day mortality was significantly less than for the robotic approach in MSQC, but there was no difference in ACS-NSQIP. CONCLUSION: Minimally invasive colorectal surgery is associated with fewer complications and has several other outcomes advantages compared with the traditional open approach. Individual complication comparisons vary between databases, and caution should be exercised when interpreting results in context.

Intraoperative hyperglycemia is independently associated with infectious complications after non-cardiac surgery.

BACKGROUND: Perioperative hyperglycemia and its associated increase in morbidity and mortality have been well studied in the critical care and cardiac surgery literature. However, there is little data regarding the impact of intraoperative hyperglycemia on post-operative infectious complications in non-cardiac surgery. METHODS: All National Surgery Quality Improvement Program patients undergoing general, vascular, and urological surgery at our tertiary care center were reviewed. After integrating intraoperative glucose measurements from our intraoperative electronic health record, we categorized patients as experiencing mild (8.3-11.0 mmol/L), moderate (11.1-16.6 mmol/L), and severe (≥ 16.7 mmol/L) intraoperative hyperglycemia. Using multiple logistic regression to adjust for patient comorbidities and surgical factors, we evaluated the association of hyperglycemia with the primary outcome of postoperative surgical site infection, pneumonia, urinary tract infection, or sepsis within 30 days. RESULTS: Of 13,954 patients reviewed, 3150 patients met inclusion criteria and had an intraoperative glucose measurement. 49% (n = 1531) of patients experienced hyperglycemia and 15% (n = 482) patients experienced an infectious complication. Patients with mild (adjusted odds ratio 1.30, 95% confidence interval [1.01 to 1.68], p-value = 0.04) and moderate hyperglycemia (adjusted odds ratio 1.57, 95% confidence interval [1.08-2.28], p-value = 0.02) had a statistically significant risk-adjusted increase in infectious complications. The model c-statistic was 0.72 [95% confidence interval 0.69-0.74]. CONCLUSIONS: This is one of the first studies to demonstrate an independent relationship between intraoperative hyperglycemia and postoperative infectious complications. Future studies are needed to evaluate a causal relationship and impact of treatment.

Evidence that a Regional Surgical Collaborative Can Transform Care: Surgical Site Infection Prevention Practices for Colectomy in Michigan.

BACKGROUND: Surgical site infections (SSI) after colectomy are associated with increased morbidity and health care use. Since 2012, the Michigan Surgical Quality Collaborative (MSQC) has promoted a "bundle" of care processes associated with lower SSI risk, using an audit-and-feedback system for adherence, face-to-face meetings, and support for quality improvement projects at participating hospitals. The purpose of this study was to determine whether practices changed over time. STUDY DESIGN: We previously found 6 processes of care independently associated with SSI in colectomy. From 2012 to 2016, we promoted a bundle of 3 care measures (cefazolin/metronidazole, oral antibiotics after mechanical bowel preparation, and normoglycemia) in 52 hospitals. Primary outcome was change in use of the 3-item SSI bundle. We also used a hierarchical logistic regression model to assess the association between 6-item compliance and SSI rate, morbidity, and health care use. RESULTS: The use of cefazolin/metronidazole increased from 18.6% to 32.3% (p < 0.001), oral antibiotic preparation increased from 42.9% to 62.0% (p < 0.001). The increase in normoglycemia was not significant. Concurrently, the SSI rate fell from 6.7% to 3.9% in the 52 hospitals (p = 0.012). Patients receiving more bundle measures had decreased rates of SSI, sepsis, and pneumonia. Morbidity and health care use significantly decreased with increased bundle compliance. CONCLUSIONS: These data show a significant increase in use of process measures promoted by a regional quality improvement collaborative, and an associated decrease in SSI after elective colectomy. These results highlight the promise of regional collaboratives to accelerate practice change and improve outcomes.

The Use of Opportunistic Salpingectomy at the Time of Benign Hysterectomy.

STUDY OBJECTIVE: To delineate the use of opportunistic salpingectomy over the study period, to examine factors associated with its use, and to evaluate whether salpingectomy was associated with perioperative complications. DESIGN: A retrospective cross-sectional study (Canadian Task Force classification II-2). SETTING: The Michigan Surgical Quality Collaborative. PATIENTS: Women undergoing ovarian-conserving hysterectomy for benign indications from January 2013 through April 2015. INTERVENTIONS: The primary outcome was the performance of opportunistic salpingectomy with ovarian preservation during benign hysterectomy. The change in the rate of salpingectomy was examined at 4-month intervals to assess a period effect over the study period. Multivariate logistic regression was performed to evaluate independent effects of patient, operative, and period factors. Perioperative outcomes were compared using propensity score matching. MEASUREMENTS AND MAIN RESULTS: There were 10 676 (55.9%) ovarian-conserving hysterectomies among 19 090 benign hysterectomies in the Michigan Surgical Quality Collaborative in the study period. The rate of opportunistic salpingectomy was 45.8% (n = 4890). Rates of opportunistic salpingectomy increased over the study period from 27.5% to 61.6% (p < .001), demonstrating a strong period effect in the consecutive 4-month period analysis. Salpingectomy was more likely with the laparoscopic approach (odds ratio = 3.48; 95% confidence interval, 3.15-3.85) and among women younger than 60 years of age (odds ratio = 1.60; 95% CI, 1.34-1.92). There was substantial variation in salpingectomy across hospital sites, ranging from 3.6% to 79.9%. Salpingectomy was associated with a 12-minute increase in operative time (p < .001), but there were no differences in the estimated blood loss or perioperative complications. CONCLUSION: The rates of salpingectomy increased significantly over the study period. The laparoscopic approach and younger age are associated with an increased probability of salpingectomy. Salpingectomy is not associated with increased blood loss or perioperative complications.
