The Michigan Surgical Quality Collaborative: Will a Statewide Quality Improvement Initiative Pay for Itself?

Variation in surgical approach and postoperative complication among older adults undergoing ventral hernia repair

BACKGROUND

Surgical decision-making for preference-sensitive operations among older adults is understudied. Ventral hernia repair (VHR) is one operation where granular data are limited to guide preoperative decision-making. We aimed to determine risk for VHR in older adults given clinically nuanced data including surgical and hernia characteristics.

METHODS

We performed a retrospective analysis of the Michigan Surgical Quality Collaborative Core Optimization Hernia Registry from January 2020 to March 2023. The primary outcome was postoperative complication across age groups: 18-64, 65-74, and ≥ 75 years, with secondary outcome of surgical approach. Mixed-effects logistic regression evaluated association between minimally invasive surgery (MIS) and 30-day complications, controlling for patient and hernia characteristics.

RESULTS

Among 8,659 patients, only 7% were 75 or older. MIS rates varied across hospitals [Median = 31.4%, IQR: (14.8-51.6%)]. The overall complication rate was 2.2%. Complication risk for undergoing open versus MIS approach did not vary between age groups; however, patients over age 75 undergoing laparoscopic repair had increased risk (aOR = 4.58, 95% CI 1.13-18.67). Other factors associated with risk included female sex (aOR = 2.10, 95% CI 1.51-2.93), higher BMI (aOR = 1.18, 95% CI 1.03-1.34), hernia width ≥ 6 cm (aOR = 3.15, 95% CI 1.96-5.04), previous repair (aOR = 1.44, 95% CI 1.02-2.05), and component separation (aOR = 1.98, 95% CI 1.28-3.05). Patients most likely to undergo MIS were female (aOR = 1.21, 95% CI 1.09-1.34), black (aOR = 1.30, 95% CI 1.12-1.52), with larger hernias: 2-5.9 cm (aOR = 1.76, 95% CI 1.57-1.97), or intraoperative mesh placement (aOR = 14.4, 95% CI 11.68-17.79). There was no difference in likelihood to receive MIS across ages when accounting for hospital (SD of baseline likelihood = 1.53, 95% CI 1.14-2.05) and surgeon (SD of baseline likelihood = 2.77, 95% CI 2.46-3.11) variation.

CONCLUSIONS

Our findings demonstrate that hernia, intraoperative, and patient characteristics other than age increase probability for complication following VHR. These findings can empower surgeons and older patients considering preoperative risk for VHR.

The Association of Cannabis Use After Discharge From Surgery With Opioid Consumption and Patient-reported Outcomes

OBJECTIVE

To compare outcomes of patients using versus not using cannabis as a treatment for pain after discharge from surgery.

BACKGROUND

Cannabis is increasingly available and is often taken by patients to relieve pain. However, it is unclear whether cannabis use for pain after surgery impacts opioid consumption and postoperative outcomes.

METHODS

Using Michigan Surgical Quality Collaborative registry data at 69 hospitals, we analyzed a cohort of patients undergoing 16 procedure types between January 1, 2021, and October 31, 2021. The key exposure was cannabis use for pain after surgery. Outcomes included postdischarge opioid consumption (primary) and patient-reported outcomes of pain, satisfaction, quality of life, and regret to undergo surgery (secondary).

RESULTS

Of 11,314 included patients (58% females, mean age: 55.1 years), 581 (5.1%) reported using cannabis to treat pain after surgery. In adjusted models, patients who used cannabis consumed an additional 1.0 (95% CI: 0.4-1.5) opioid pills after surgery. Patients who used cannabis were more likely to report moderate-to-severe surgical site pain at 1 week (adjusted odds ratio: 1.7, 95% CIL 1.4-2.1) and 1 month (adjusted odds ratio: 2.1, 95% CI: 1.7-2.7) after surgery. Patients who used cannabis were less likely to endorse high satisfaction (72.1% vs 82.6%), best quality of life (46.7% vs 63.0%), and no regret (87.6% vs 92.7%) (all P < 0.001).

CONCLUSIONS

Patient-reported cannabis use, to treat postoperative pain, was associated with increased opioid consumption after discharge from surgery that was of clinically insignificant amounts, but worse pain and other postoperative patient-reported outcomes.

Variability in surgical approaches to hernias in patients with ascites

BACKGROUND

Hernias in patients with ascites are common, however we know very little about the surgical repair of hernias within this population. The study of these repairs has largely remained limited to single center and case studies, lacking a population-based study on the topic.

STUDY DESIGN

The Michigan Surgical Quality Collaborative and its corresponding Core Optimization Hernia Registry (MSQC-COHR) which captures specific patient, hernia, and operative characteristics at a population level within the state was used to conduct a retrospective review of patients with ascites undergoing ventral or inguinal hernia repair between January 1, 2020 and May 3, 2022. The primary outcome observed was incidence and surgical approach for both ventral and inguinal hernia cohorts. Secondary outcomes included 30-day adverse clinical outcomes as listed here: (ED visits, readmission, reoperation and complications) and surgical priority (urgent/emergent vs elective).

RESULTS

In a cohort of 176 patients with ascites, surgical repair of hernias in patients with ascites is a rare event (1.4% in ventral hernia cohort, 0.2% in inguinal hernia cohort). The post-operative 30-day adverse clinical outcomes in both cohorts were greatly increased compared to those without ascites (ventral: 32% inguinal: 30%). Readmission was the most common complication in both inguinal (n = 14, 15.9%) and ventral hernia (n = 17, 19.3%) groups. Although open repair was most common for both cohorts (ventral: 86%, open: 77%), minimally invasive (MIS) approaches were utilized. Ventral hernias presented most commonly urgently/emergently (60%), and in contrast many inguinal hernias presented electively (72%).

CONCLUSION

A population-level, ventral and incisional hernia database capturing operative details for 176 patients with ascites. There was variation in the surgical approaches performed for this rare event and opportunities for optimization in patient selection and timing of repair.

Validation of measures for perioperative urinary catheter use, urinary retention, and urinary catheter-related trauma in surgical patients

BACKGROUND

The effects of non-infectious urinary catheter-related complications such as measurements of indwelling urinary catheter overuse, catheter-related trauma, and urinary retention are not well understood.

METHODS

This was a retrospective cohort study of 200 patients undergoing general surgery operations. Variables to measure urinary catheter use, trauma, and retention were developed, then surgical cases were abstracted. Inter- and intra-rater reliability were calculated for measure validation.

RESULTS

129 of 200 (65%) had an indwelling urinary catheter placed at the time of surgery. 32 patients (16%) had urinary retention, and variation was observed in the treatment of urinary retention. 12 patients (6%) had urinary trauma. Rater reliability was high (>90% agreement for all) for the dichotomous outcomes of urinary catheter use, urinary catheter-related trauma, and urinary retention.

CONCLUSIONS

This study suggests a persistent high rate of catheter use, significant rates of urinary retention and trauma, and variation in the management of retention.

Use of statewide financial incentives to improve documentation of hernia and mesh characteristics in ventral hernia repair

BACKGROUND

Documentation of intraoperative details is critical for understanding and advancing hernia care, but is inconsistent in practice. Therefore, to improve data capture on a statewide level, we implemented a financial incentive targeting documentation of hernia defect size and mesh use.

METHODS

The Abdominal Hernia Care Pathway (AHCP), a voluntary pay for performance (P4P) initiative, was introduced in 2021 within the statewide Michigan Surgical Quality Collaborative (MSQC). This consisted of an organizational-level financial incentive for achieving 80% performance on eight specific process measures for ventral hernia surgery, including complete documentation of hernia defect size and location, as well as mesh characteristics and fixation technique. Comparisons were made between AHCP and non-AHCP sites in 2021.

RESULTS

Of 69 eligible sites, 47 participated in the AHCP in 2021. There were N = 5362 operations (4169 at AHCP sites; 1193 at non-AHCP sites). At AHCP sites, 69.8% of operations had complete hernia documentation, compared to 50.5% at non-AHCP sites (p < 0.0001). At AHCP sites, 91.4% of operations had complete mesh documentation, compared to 86.5% at non-AHCP sites (p < 0.0001). The site-level hernia documentation goal of 80% was reached by 14 of 47 sites (range 14-100%). The mesh documentation goal was reached by 41 of 47 sites (range 4-100%).

CONCLUSIONS

Addition of an organizational-level financial incentive produced marked gains in documentation of intra-operative details across a statewide surgical collaborative. The relatively large effect size-19.3% for hernia-is remarkable among P4P initiatives. This result may have been facilitated by surgeons' direct role in documenting hernia size and mesh use. These improvements in data capture will foster understanding of current hernia practices on a large scale and may serve as a model for improvement in collaboratives nationally.

Reducing Ileostomy Readmissions: Using Implementation Science to Evaluate the Adoption of a Quality Improvement Initiative

BACKGROUND

Translating empirical evidence into clinical practice remains challenging. Prevention of morbidity from new ileostomies may serve as an example. Despite evidence demonstrating improvements in electrolyte levels, kidney function markers, and hospital readmissions, widespread adoption of oral rehydration solutions among patients with new ileostomies has not occurred. The causes of low uptake are unknown and likely multifactorial.

OBJECTIVE

We used the Reach, Effectiveness, Adoption, Implementation, and Maintenance implementation science framework to identify barriers and facilitators in the adoption of a quality improvement initiative aimed at decreasing emergency department visits and hospital readmissions because of dehydration among patients with new ileostomies using oral rehydration solutions.

DESIGN

Qualitative interviews were conducted with stakeholders based on the domains of the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework.

SETTINGS

Participating community and academic hospitals across Michigan (n = 12).

PATIENTS

Convenience sampling was used to recruit 25 key stakeholders, including wound, ostomy, and continence nurses; registered nurses; nurse practitioners; nurse managers; colorectal surgeons; surgery residents; physician assistants; and data abstractors (1-4 participants per site).

MAIN OUTCOME MEASURES

Through qualitative content analysis, we located, analyzed, and identified patterns using the Reach, Effectiveness, Adoption, Implementation, and Maintenance framework.

RESULTS

We identified the following factors to increase the adoption of quality improvement initiatives at the provider level: 1) selection and coaching of champions, 2) broadening of multidisciplinary teams, 3) performing structured patient follow-up, and 4) addressing long-term sustainability concerns regarding cost and equity.

LIMITATIONS

Limited to high-volume ileostomy surgery hospitals, did not include in-person site visits to each hospital before and after implementation, and did not consider the hospital- and patient-level factors that impact the widespread adoption of quality improvement initiatives.

CONCLUSIONS

Integrating implementation science frameworks to rigorously study quality improvement initiatives may reveal the determinants of the widespread adoption of evidence-based practices.

Does Anesthesia Quality Improvement Participation Lead to Incremental Savings in a Surgical Quality Collaborative Population? A Retrospective Observational Study

BACKGROUND

The Anesthesiology Performance Improvement and Reporting Exchange (ASPIRE) Collaborative Quality Initiative (CQI) was launched as a partnership among hospitals to measure quality, review evidence-based practices, and improve anesthesia-related outcomes. Cost savings and improved patient outcomes have been associated with surgical CQI participation, but the impact of an anesthesia CQI on health care cost has not been thoroughly assessed. In this study, we evaluated whether participation in an anesthesia CQI led to health care savings. We hypothesized that ASPIRE participation is associated with reduced total episode payments for payers and major, high-volume procedures included in the Michigan Value Collaborative (MVC) registry.

METHODS

In this retrospective observational study, we compared MVC episode payment data from Group 1 ASPIRE hospitals, the first cluster of 8 Michigan hospitals to join ASPIRE in January 2015, to non-ASPIRE matched control hospitals. MVC computes price-standardized, risk-adjusted payments for patients insured by Blue Cross Blue Shield of Michigan Preferred Provider Organization, Blue Care Network Health Maintenance Organization, and Medicare Fee-for-Service plans. Episodes from 2014 comprised the pre-ASPIRE time period, and episodes from June 2016 to July 2017 constituted the post-ASPIRE time period. We performed a difference-in-differences analysis to evaluate whether ASPIRE implementation was associated with greater reduction in total episode payments compared to the change in the control hospitals during the same time periods.

RESULTS

We found a statistically significant reduction in total episode (-$719; 95% CI [-$1340 to -$97]; P = .023) payments at the 8 ASPIRE hospitals (N = 17,852 cases) compared to the change observed in 8 matched non-ASPIRE hospitals (N = 12,987 cases) for major, high-volume surgeries, including colectomy, colorectal cancer resection, gastrectomy, esophagectomy, pancreatectomy, hysterectomy, joint replacement (knee and hip), and hip fracture repair. In secondary analyses, 30-day postdischarge (-$354; 95% CI [-$582 to -$126]; P = .002) payments were also significantly reduced in ASPIRE hospitals compared to non-ASPIRE controls. Subgroup analyses revealed a significant reduction in total episode payments for joint replacements (-$860; 95% CI [-$1222 to -$499]; P < .001) at ASPIRE-participating hospitals. Sensitivity analyses including patient-level covariates also showed consistent results.

CONCLUSIONS

Participation in an anesthesiology CQI, ASPIRE, is associated with lower total episode payments for selected major, high-volume procedures. This analysis supports that participation in an anesthesia CQI can lead to reduced health care payments.

Hospital spending and length of stay attributable to perioperative adverse events for inpatient hip, knee, and spine surgery: a retrospective cohort study

BACKGROUND

The incremental hospital cost and length of stay (LOS) associated with adverse events (AEs) has not been well characterized for planned and unplanned inpatient spine, hip, and knee surgeries.

METHODS

Retrospective cohort study of hip, knee, and spine surgeries at an academic hospital in 2011-2012. Adverse events were prospectively collected for 3,063 inpatient cases using the Orthopaedic Surgical AdVerse Event Severity (OrthoSAVES) reporting tool. Case costs were retrospectively obtained and inflated to equivalent 2021 CAD values. Propensity score methodology was used to assess the cost and LOS attributable to AEs, controlling for a variety of patient and procedure factors.

RESULTS

The sample was 55% female and average age was 64; 79% of admissions were planned. 30% of cases had one or more AEs (82% had low-severity AEs at worst). The incremental cost and LOS attributable to AEs were $8,500 (95% confidence interval [CI]: 5100-11,800) and 4.7 days (95% CI: 3.4-5.9) per admission. This corresponded to a cumulative $7.8 M (14% of total cohort cost) and 4,290 bed-days (19% of cohort bed-days) attributable to AEs. Incremental estimates varied substantially by (1) admission type (planned: $4,700/2.4 days; unplanned: $20,700/11.5 days), (2) AE severity (low: $4,000/3.1 days; high: $29,500/11.9 days), and (3) anatomical region (spine: $19,800/9 days; hip: $4,900/3.8 days; knee: $1,900/1.5 days). Despite only 21% of admissions being unplanned, adverse events in these admissions cumulatively accounted for 59% of costs and 62% of bed-days attributable to AEs.

CONCLUSIONS

This study comprehensively demonstrates the considerable cost and LOS attributable to AEs in orthopaedic and spine admissions. In particular, the incremental cost and LOS attributable to AEs per admission were almost five times as high among unplanned admissions compared to planned admissions. Mitigation strategies focused on unplanned surgeries may result in significant quality improvement and cost savings in the healthcare system.

Changes in Surgical Opioid Prescribing and Patient-Reported Outcomes After Implementation of an Insurer Opioid Prescribing Limit

Importance

Insurers are increasingly limiting the duration of opioid prescriptions for acute pain. Among patients undergoing surgery, it is unclear whether implementation of these limits is associated with changes in opioid prescribing and patient-reported outcomes, such as pain.

Objective

To assess changes in surgical opioid prescribing and patient-reported outcomes after implementation of an opioid prescribing limit by a large commercial insurer in Michigan.

Design, Setting, and Participants

This was a cross-sectional study with an interrupted time series analysis. Data analyses were conducted from October 1, 2022, to February 28, 2023. The primary data source was the Michigan Surgical Quality Collaborative, a statewide registry containing data on opioid prescribing and patient-reported outcomes from adults undergoing common general surgical procedures. This registry is linked to Michigan's prescription drug monitoring program database, allowing observation of opioid dispensing. The study included 6045 adults who were covered by the commercial insurer and underwent surgery from January 1, 2017, to October 31, 2019.

Exposure

Policy limiting opioid prescriptions to a 5-day supply in February 2018.

Main Outcomes and Measures

Among all patients, segmented regression models were used to assess for level or slope changes during February 2018 in 3 patient-reported outcomes: pain in the week after surgery (assessed on a scale of 1-4: 1 = none, 2 = minimal, 3 = moderate, and 4 = severe), satisfaction with surgical experience (scale of 0-10, with 10 being the highest satisfaction), and amount of regret regarding undergoing surgery (scale of 1-5, with 1 being the highest level of regret). Among patients with a discharge opioid prescription and a dispensed opioid prescription (prescription filled within 3 days of discharge), additional outcomes included total morphine milligram equivalents in these prescriptions, a standardized measure of opioid volume.

Results

Among the 6045 patients included in the study, mean (SD) age was 48.7 (12.6) years and 3595 (59.5%) were female. Limit implementation was not associated with changes in patient-reported satisfaction or regret and was associated with only a slight level decrease in patient-reported pain score (-0.15 [95% CI, -0.26 to -0.03]). Among 4396 patients (72.7%) with a discharge and dispensed opioid prescription, limit implementation was associated with a -22.3 (95% CI, -32.8 to -11.9) and -26.1 (95% CI, -40.9 to -11.3) level decrease in monthly mean total morphine milligram equivalents of discharge and dispensed opioid prescriptions, respectively. These decreases corresponded approximately to 3 to 3.5 pills containing 5 mg of oxycodone.

Conclusions

This cross-sectional analysis of data from adults undergoing general surgical procedures found that implementation of an insurer's limit was associated with modest reductions in opioid prescribing but not with worsened patient-reported outcomes. Whether these findings generalize to other procedures warrants further study.

The impact of frailty on ventral hernia repair outcomes in a statewide database

INTRODUCTION

Preoperative frailty is a strong predictor of postoperative morbidity in the general surgery population. Despite this, there are a paucity of research examining the effect of frailty on outcomes after ventral hernia repair (VHR), one of the most common abdominal operations in the USA. We examined the association of frailty with short-term postoperative outcomes while accounting for differences in preoperative, operative, and hernia characteristics.

METHODS

We retrospectively reviewed the Michigan Surgery Quality Collaborative Hernia Registry (MSQC-HR) for adult patients who underwent VHR between January 2020 and January 2022. Patient frailty was assessed using the validated 5-factor modified frailty index (mFI5) and categorized as follows: no (mFI5 = 0), moderate (mFI5 = 1), and severe frailty (mFI5 ≥ 2). Our primary outcome was any 30-day complication. Multivariable logistic regression was used to evaluate the association of frailty with outcomes while controlling for patient, operative, and hernia variables.

RESULTS

A total of 4406 patients underwent VHR with a mean age (SD) of 55 (15) years, 2015 (46%) females, and 3591 (82%) white patients. The mean (SD) BMI of the cohort was 33 (8) kg/m2. A total of 2077 (47%) patients had no frailty, 1604 (36%) were moderately frail, and 725 (17%) were severely frail. The median hernia size (interquartile range) was 2.5 cm (1.5-4.0 cm). Severe frailty was associated with increased odds of any complication (adjusted Odds Ratio (aOR) 3.12, 95% CI 1.78-5.47), serious complication (aOR 5.25, 95% CI 2.17-13.19), SSI (aOR 3.41, 95% CI 1.58-7.34), and post-discharge adverse events (aOR 1.70, 95% CI 1.24-2.33).

CONCLUSION

After controlling for patient, operative, and hernia characteristics, frailty was independently associated with increased odds of postoperative complications. These findings highlight the importance of preoperative frailty assessment for risk stratification and to inform patient counseling.

Postoperative Opioid Prescribing and New Persistent Opioid Use: The Risk of Excessive Prescribing

OBJECTIVE

Evaluate the association between postoperative opioid prescribing and new persistent opioid use.

SUMMARY BACKGROUND DATA

Opioid-nave patients who develop new persistent opioid use after surgery are at increased risk of opioid-related morbidity and mortality. However, the extent to which postoperative opioid prescribing is associated with persistent postoperative opioid use is unclear.

METHODS

Retrospective study of opioid-naïve adults undergoing surgery in Michigan from 1/1/2017 to 10/31/2019. Postoperative opioid prescriptions were identified using a statewide clinical registry and prescription fills were identified using Michigan's prescription drug monitoring program. The primary outcome was new persistent opioid use, defined as filling at least 1 opioid prescription between post-discharge days 4 to 90 and filling at least 1 opioid prescription between post-discharge days 91 to 180.

RESULTS

A total of 37,654 patients underwent surgery with a mean age of 52.2 (16.7) years and 20,923 (55.6%) female patients. A total of 31,920 (84.8%) patients were prescribed opioids at discharge. Six hundred twenty-two (1.7%) patients developed new persistent opioid use after surgery. Being prescribed an opioid at discharge was not associated with new persistent opioid use [adjusted odds ratio (aOR) 0.88 (95% confidence interval (CI) 0.71-1.09)]. However, among patients prescribed an opioid, patients prescribed the second largest [12 (interquartile range (IQR) 3) pills] and largest [20 (IQR 7) pills] quartiles of prescription size had higher odds of new persistent opioid use compared to patients prescribed the smallest quartile [7 (IQR 1) pills] of prescription size [aOR 1.39 (95% CI 1.04-1.86) andaOR 1.97 (95% CI 1.442.70), respectively].

CONCLUSIONS

In a cohort of opioid-naïve patients undergoing common surgical procedures, the risk of new persistent opioid use increased with the size of the prescription. This suggests that while opioid prescriptions in and of themselves may not place patients at risk of long-term opioid use, excessive prescribing does. Consequently, these findings support ongoing efforts to mitigate excessive opioid prescribing after surgery to reduce opioid-related harms.

Truth of Colorectal Enhanced Recovery Programs: Process Measure Compliance in 151 Hospitals

BACKGROUND

Commonly cited studies have reported substantial improvements (defined as >20%) in process measure compliance after implementation of colorectal enhanced recovery programs (ERPs). However, hospitals have anecdotally reported difficulties in achieving similar improvement gains. This study evaluates improvement uniformity among 151 hospitals exposed to an 18-month implementation protocol for 6 colorectal ERP process measures (oral antibiotics, mechanical bowel preparation, multimodal pain control, early mobilization, early liquid intake, and early solid intake).

STUDY DESIGN

One hundred fifty-one hospitals implemented a colorectal ERP with pathway, educational and supporting materials, and data capture protocols; 906 opportunities existed for process compliance improvement across the cohort (151 hospitals × 6 process measures). However, 240 opportunities were excluded due to high starting compliance rates (ie compliance >80%) and 3 opportunities were excluded because compliance rates were recorded for fewer than 2 cases. Thus, 663 opportunities for improvement across 151 hospitals were studied.

RESULTS

Of 663 opportunities, minimal improvement (0% to 20% increase in compliance) occurred in 52% of opportunities, substantial improvement (>20% increase in compliance) in 20%, and worsening compliance occurred in 28%. Of the 6 processes, multimodal pain control and use of oral antibiotics improved the most.

CONCLUSIONS

Contrary to published ERP literature, the majority of study hospitals had difficulty improving process compliance with 80% of the opportunities not achieving substantial improvement. This discordance between ERP implementation success rates reported in the literature and what is observed in a large sample could reflect differences in hospitals' culture or characteristics, or a publication bias. Attention needs to be directed toward improving ERP adoption across the spectrum of hospital types.

Heterogeneity in Surgical Quality Improvement in Michigan

OBJECTIVE

The aim of this study was to evaluate changes in 30-day postoperative outcomes and individual hospital variation in outcomes from 2012 to 2019 in a collaborative quality improvement network.

SUMMARY BACKGROUND DATA

Collaborative quality improvement efforts have been shown to improve postoperative outcomes overall; however, heterogeneity in improvement between participating hospitals remains unclear. Understanding the distribution of individual hospital-level changes is necessary to inform resource allocation and policy design.

METHODS

We performed a retrospective cohort study of 51 hospitals in the Michigan Surgical Quality Collaborative (MSQC) from 2012 to 2019. Risk-and reliability-adjusted hospital rates of 30-day mortality, complications, serious complications, emergency department (ED) visits, readmissions, and reoperations were calculated for each year and compared between the last 2 years and the first 2 years of the study period.

RESULTS

There was a significant decrease in the rates of all 5 adverse outcomes across MSQC hospitals from 2012 to 2019. Of the 51 individual hospitals, 31 (61%) hospitals achieved a decrease in mortality (range -1.3 percentage points to +0.6 percentage points), 40 (78%) achieved a decrease in complications (range -8.5 percentage points to +2.9 percentage points), 26 (51%) achieved a decrease in serious complications (range -3.2 percentage points to +3.0 percentage points), 29 (57%) achieved a decrease in ED visits (range 5.0 percentage points to +2.2 percentage points), 46 (90%) achieved a decrease in readmissions (range -3.1 percentage points to +0.4 percentage points) and 39 (76%) achieved a decrease in reoperations (range 3.3 percentage points to +1.0 percentage points).

CONCLUSIONS

Despite overall improvement in surgical outcomes across hospitals participating in a quality improvement collaborative, there was substantial variation in improvement between hospitals, highlighting opportunities to better understand hospital-level barriers and facilitators to surgical quality improvement.

Development of the Illinois Surgical Quality Improvement Collaborative (ISQIC): Implementing 21 Components to Catalyze Statewide Improvement in Surgical Care

INTRODUCTION

In 2014, 56 Illinois hospitals came together to form a unique learning collaborative, the Illinois Surgical Quality Improvement Collaborative (ISQIC). Our objectives are to provide an overview of the first three years of ISQIC focused on (1) how the collaborative was formed and funded, (2) the 21 strategies implemented to support quality improvement (QI), (3) collaborative sustainment, and (4) how the collaborative acts as a platform for innovative QI research.

METHODS

ISQIC includes 21 components to facilitate QI that target the hospital, the surgical QI team, and the peri-operative microsystem. The components were developed from available evidence, a detailed needs assessment of the hospitals, reviewing experiences from prior surgical and non-surgical QI Collaboratives, and interviews with QI experts. The components comprise 5 domains: guided implementation (e.g., mentors, coaches, statewide QI projects), education (e.g., process improvement (PI) curriculum), hospital- and surgeon-level comparative performance reports (e.g., process, outcomes, costs), networking (e.g., forums to share QI experiences and best practices), and funding (e.g., for the overall program, pilot grants, and bonus payments for improvement).

RESULTS

Through implementation of the 21 novel ISQIC components, hospitals were equipped to use their data to successfully implement QI initiatives and improve care. Formal (QI/PI) training, mentoring, and coaching were undertaken by the hospitals as they worked to implement solutions. Hospitals received funding for the program and were able to work together on statewide quality initiatives. Lessons learned at one hospital were shared with all participating hospitals through conferences, webinars, and toolkits to facilitate learning from each other with a common goal of making care better and safer for the surgical patient in Illinois. Over the first three years, surgical outcomes improved in Illinois.

DISCUSSION

The first three years of ISQIC improved care for surgical patients across Illinois and allowed hospitals to see the value of participating in a surgical QI learning collaborative without having to make the initial financial investment themselves. Given the strong support and buy-in from the hospitals, ISQIC has continued beyond the initial three years and continues to support QI across Illinois hospitals.

Application of Component Separation and Short-Term Outcomes in Ventral Hernia Repairs

INTRODUCTION

Component separation (CS) techniques have evolved in recent years. How surgeons apply the various CS techniques, anterior component separation (aCS) versus posterior component separation (pCS), by patient and hernia-specific factors remain unknown in the general population. Improving the quality of ventral hernia repair (VHR) on a large scale requires an understanding of current practice variations and how these variations ultimately affect patient care. In this study, we examine the application of CS techniques and the associated short-term outcomes while taking into consideration patient and hernia-specific factors.

METHODS

We retrospectively reviewed a clinically rich statewide hernia registry, the Michigan Surgical Quality Collaborative Hernia Registry, of persons older than 18 y who underwent VHR between January 2020 and July 2021. The exposure of interest was the use of CS. Our primary outcome was a composite end point of 30-d adverse events including any complication, emergency department visit, readmission, and reoperation. Our secondary outcome was surgical site infection (SSI). Multivariable logistic regression examined the association of CS use, 30-d adverse events, and SSI with patient-, hernia-, and operative-specific variables. We performed a sensitivity analysis evaluating for differences in application and outcomes of the posterior and aCS techniques.

RESULTS

A total of 1319 patients underwent VHR, with a median age (interquartile range) of 55 y (22), 641 (49%) female patients, and a median body mass index of 32 (9) kg/m². CS was used in 138 (11%) patients, of which 101 (73%) were pCS and 37 (27%) were aCS. Compared to patients without CS, patients undergoing a CS had larger median hernia widths (2.5 cm (range 0.01-23 cm) versus 8 cm (1-30 cm), P < 0.001). Of the CS cases, 49 (36%) performed in hernias less than 6 cm in size. Following multivariate regression, factors independently associated with the use of a CS were diabetes (odds ratio [OR]: 2.00, 95% confidence interval [CI]: 1.19-3.36), previous hernia repair (OR: 1.88, 95% CI: 1.20-2.96), hernia width (OR: 1.28, 95% CI: 1.22-1.34), and an open approach (OR: 3.83, 95% CI: 2.24-6.53). Compared to patients not having a CS, use of a CS was associated with increased odds of 30-d adverse events (OR: 1.88 95% CI: 1.13-3.12) but was not associated with SSI (OR: 1.95, 95% CI: 0.74-4.63). Regression analysis demonstrated no differences in 30-d adverse events or SSI between the pCS and aCS techniques.

CONCLUSIONS

This is the first population-level report of patients undergoing VHR with concurrent posterior or aCS. These data suggest wide variation in the application of CS in VHR and raises a concern for potential overutilization in smaller hernias. Continued analysis of CS application and the associated outcomes, specifically recurrence, is necessary and underway.

The Association of Postoperative Opioid Prescriptions with Patient Outcomes

OBJECTIVE

To compare outcomes after surgery between patients who were not prescribed opioids and patients who were prescribed opioids.

SUMMARY OF BACKGROUND DATA

Postoperative opioid prescriptions carry significant risks. Understanding outcomes among patients who receive no opioids after surgery may inform efforts to reduce these risks.

METHODS

We performed a retrospective study of adult patients who underwent surgery between January 1, 2019 and October 31, 2019. The primary outcome was the composite incidence of an emergency department visit, readmission, or reoperation within 30 days of surgery. Secondary outcomes were postoperative pain, satisfaction, quality of life, and regret collected via postoperative survey. A multilevel, mixed-effects logistic regression was performed to evaluate differences between groups.

RESULTS

In a cohort of 22,345 patients, mean age (standard deviation) was 52.1 (16.5) years and 13,269 (59.4%) patients were female. About 3175 (14.2%) patients were not prescribed opioids, of whom 422 (13.3%) met the composite adverse event endpoint compared to 2255 (11.8%) of patients not prescribed opioids ( P = 0.015). Patients not prescribed opioids had a similar probability of adverse events {11.7% [95% confidence interval (CI) 10.2%-13.2%] vs 11.9% (95% CI 10.6%-13.3%]}. Among 12,872 survey respondents, patients who were not prescribed an opioid had a similar rate of high satisfaction [81.7% (95% CI 77.3%-86.1%) vs 81.7% (95% CI 77.7%- 85.7%)] and no regret [(93.0% (95% CI 90.8%-95.2%) vs 92.6% (95% CI 90.4%-94.7%)].

CONCLUSIONS

Patients who were not prescribed opioids after surgery had similar clinical and patient-reported outcomes as patients who were prescribed opioids. This suggests that minimizing opioids as part of routine postoperative care is unlikely to adversely affect patients.

Variation in approach for small (< 2 cm) ventral hernias across a statewide quality improvement collaborative

INTRODUCTION

Operative technique for hernias < 2 cm is highly controversial. Limited data exist about this practice at a population level. Within this context we sought to describe practice patterns and use of mesh among patients undergoing repair of small hernias within the setting of a statewide quality improvement collaborative.

METHODS

Retrospective cohort study of patients undergoing hernia repair in the Michigan Surgical Quality Collaborative Hernia Registry was conducted. Patients who underwent repair of a hernia < 2 cm from January 1, 2020 to July 8, 2021 were included. Descriptive statistics were performed to describe cohort characteristics and compare patients who did and did not receive mesh. Logistic regression was performed to estimate the odds of receiving mesh after accounting for patient and hernia characteristics.

RESULTS

Among 570 patients, 56.1% (n = 320) had mesh placed. Most repairs were conducted via open approach (n = 437, 76.5%). Patients who received mesh were older (51.8 vs 48.6, p < 0.01), had higher BMI (31.7 vs 30.0, p < 0.01), were more often ASA Class III (35.9% vs 24.4%, p < 0.01), more often had diabetes (15.9% vs 10.0%, 0.04) and hypertension (44.7% vs 30.4%, p < 0.01), and had higher hernia width (1.2 cm vs 1.0 cm, p < 0.0001). After adjustment, ASA Class III (aOR 3.41, 95% CI 1.31-8.89), current smoking status (aOR 1.81, 95% CI 1.04-3.18), higher mean hernia width (aOR 5.68, 95% CI 2.97-10.85), and laparoscopic (aOR 12.9, 95% CI 5.02-32.96) or robotic (aOR 24.3, 95% CI 6.96-84.96) were associated with mesh use, while COPD (aOR 0.36, 95% CI 0.07-0.96) was associated with less mesh use.

CONCLUSIONS

Use of mesh for small hernias remains controversial. We found that patients who had mesh placed at the time of surgery were potentially patients at higher risk for complications. The decision to use mesh may be driven by patient-related factors that predispose to complications and operative recurrence rather than evidence indicating that it is superior in this population.

The Michigan Radiation Oncology Quality Consortium: A Novel Initiative to Improve the Quality of Radiation Oncology Care

PURPOSE

Numerous quality measures have been proposed in radiation oncology, and initiatives to improve access to high-complexity care, quality, and equity are needed. We describe the design and evaluate impact of a voluntary statewide collaboration for quality improvement in radiation oncology initiated a decade ago.

METHODS AND MATERIALS

We evaluate compliance before and since implementation of annual metrics for quality improvement, using an observational dataset with information from over 20,000 patients treated in the 28 participating radiation oncology practices. At thrice-yearly meetings, experts have spoken regarding trends within the field and inspired discussions regarding potential targets for quality improvement. Blinded data on practices at various sites have been provided. Following Standards for Quality Improvement Reporting Excellence (SQUIRE) guidelines, we describe the approach and measures the program has implemented. To evaluate impact, we compare compliance at baseline and now with active measures using mixed effects regression models with site-level random effects.

RESULTS

Compliance has increased, including use of guideline-concordant hypofractionated radiotherapy, doses to targets/normal tissues, motion management, and consistency in delineating and naming contoured structures (a precondition for quality evaluation). For example, use of guideline-concordant hypofractionation for breast cancer increased from 47% to 97%, adherence to target coverage goals and heart dose limits for dose increased from 46% to 86%, motion assessment in patients with lung cancer increased from 52% to 94%, and use of standard nomenclature increased from 53% to 82% for lung patients and from 80% to 94% for breast patients (all p<0.001).

CONCLUSIONS

Although observational analysis cannot fully exclude secular trends, contextual data revealing slow uptake of best practices elsewhere in the US and qualitative feedback from participants suggests that this initiative has improved the consistency, efficiency, and quality of radiation oncology care in its member practices and may be a model for oncology quality improvement more generally.

Emergency General Surgery Quality Improvement: A Review of Recommended Structure and Key Issues

Emergency general surgery (EGS) accounts for 11% of hospital admissions, with more than 3 million admissions per year and more than 50% of operative mortality in the US. Recent research into EGS has ignited multiple quality improvement initiatives, and the process of developing national standards and verification in EGS has been initiated. Such programs for quality improvement in EGS include registry formation, protocol and standards creation, evidenced-based protocols, disease-specific protocol implementation, regional collaboratives, targeting of high-risk procedures such as exploratory laparotomy, focus on special populations like geriatrics, and targeting improvements in high opportunity outcomes such as failure to rescue. The authors present a collective narrative review of advances in quality improvement structure in EGS in recent years and summarize plans for a national EGS registry and American College of Surgeons verification for this under-resourced area of surgery.

Guideline-discordant care among females undergoing groin hernia repair: the importance of sex as a biologic variable

PURPOSE

Females suffer higher rates of operative recurrence and chronic pain following groin hernia repair. Guidelines recommend minimally invasive (MIS) groin hernia repair as the preferred approach to reduce these adverse outcomes. It is unknown what proportion of females receive MIS hernia repair. Therefore, our goal was to investigate adoption of evidence-based practices in groin hernia repair using sex as a biological variable.

METHODS

Retrospective cohort study of adults undergoing elective groin hernia repair (2014-2019) within a statewide quality improvement collaborative. Primary outcome was surgical approach. Multivariable logistic regression was performed to analyze the likelihood of undergoing MIS hernia repair. Secondary outcomes were 30-day adjusted rates of clinical and patient-reported outcomes (PROs). PROs included regret to undergo surgery among patients who completed post-operative surveys.

RESULTS

Among 23,723 patients, the majority (90.7%) were males. Compared to males, females less often underwent an MIS surgical approach (37.4% vs 45.1%, p < 0.0001). After adjustment for patient and clinical variables, females remained significantly less likely to undergo MIS groin hernia repair (aOR 0.88, 95% CI 0.80-0.97). Adjusted clinical outcomes were not different between males and females. Among 4325 patients who completed post-operative surveys, adjusted rates of regret to undergo surgery were higher among females (12.9% vs 8.5%, p = 0.003).

CONCLUSIONS

Even after adjusting for differences, females were less likely to receive guideline-concordant groin hernia repair and were more likely to regret surgery. Understanding the behaviors of surgeons who treat females with groin hernia may inform quality metrics to promote best practices in this population.

Successful Implementation of Enhanced Recovery in Elective Colorectal Surgery is Variable and Dependent on the Local Environment

OBJECTIVE

To evaluate local hospital success with enhanced recovery implementation as measured by colorectal surgery process measure (PM) compliance and characterize local environment factors associated with success within a contemporary quality improvement collaborative.

SUMMARY BACKGROUND DATA

Enhanced recovery programs (ERP) have proven an effective perioperative quality improvement strategy, but local variation in implementation can hinder patient outcome improvement.

METHODS

Individual hospitals participating in a national colorectal ERP quality improvement program were evaluated with quantitative (patient-level process and outcome) and qualitative (survey and structured interviews with hospital teams) data between 2017 and 2020. Hospitals with implementation success were identified: high performers (80% of elective colorectal surgery patients compliant with >6/9 PMs) and high improvers (top quartile of PM adherence improvement over time). Hospital and implementation characteristics were compared with chi-square tests. Trends in average annual outcome change were estimated with logistic and linear regression.

RESULTS

Of 207 total hospitals, 62 were characterized as High Performance and 52 as High Improvement. High Performance hospitals were larger, with more annual colorectal surgeries (128 vs 101, P = 0.039). Qualitative assessment revealed fewer barriers of staff buy-in and competing priorities, and more experience with standardized perioperative care in High Performance hospitals. High Improvement hospitals had lower baseline PM adherence (54.1% vs 69.6%, P < 0.001) and less experience with standardized perioperative care (30.8% vs 58.1%, P < 0.001) but were noted to have a positive trend in annual patient outcomes: annual morbidity (Δ-1.14% vs -0.20%, P = 0.035), readmission (Δ-1.85% vs 0.002%, P = 0.037), and prolonged length of stay (Δ-3.94 vs -1.19, P = 0.037) compared to Low Improvement hospitals.

CONCLUSIONS

When evaluating a collection of hospitals implementing ERP, only half of hospitals reached consistent High Performance or high improvement. Characteristics of the local environment need further study to understand the barriers to effective implementation in a pragmatic setting.

The Impact of Complications and Pain on Patient Satisfaction

OBJECTIVE

To measure the association between patient-reported satisfaction and regret and clinical outcomes.

SUMMARY OF BACKGROUND DATA

Patient-reported outcomes are becoming an increasingly important marker of the quality of patient care. It is unclear however, how well patient-reported outcomes adequately reflect care quality and clinical outcomes in surgical patients.

METHODS

Retrospective, population-based analysis of adults ages 18 and older undergoing surgery across 38 hospitals in Michigan between January 1, 2017 and May 31, 2018.

RESULTS

In this study, 9953 patients (mean age 56 years; 5634 women (57%)) underwent 1 of 16 procedures. 9550 (96%) patients experienced no complication, whereas 240 (2%) and 163 (2%) patients experienced Grade 1 and Grade 2-3 complications, respectively. Postoperative pain scores were: none (908 (9%) patients), mild (3863 (40%) patients), moderate (3893 (40%) patients), and severe (1075 (11%) patients). Overall, 7881 (79%) patients were highly satisfied and 8911 (91%) had absolutely no regret after surgery. Patients were less likely to be highly satisfied if they experienced a Grade 1 complication [odds ratio (OR) 0.50, 95% confidence interval (CI) 0.37-0.66], Grade 2-3 complication (OR 0.44, 95% CI 0.31-0.62), minimal pain (OR 0.80, 95% CI 0.64-0.99, moderate pain (OR 0.39, 95% CI 0.32-0.49), or severe pain (OR 0.23, 95% CI 0.18-0.29). Patients were less likely to have no regret if they experienced a Grade 1 complication (OR 0.48, 95% CI 0.33-0.70), Grade 2-3 complication (OR 0.39, 95% CI 0.25-0.60), moderate pain (OR 0.55, 95% CI 0.40-0.76), or severe pain (OR 0.22, 95% CI 0.16-0.31). The predicted probability of being highly satisfied was 79% for patients who had no complications and 88% for patients who had no pain.

CONCLUSIONS

Patients who experienced postoperative complications and pain were less likely to be highly satisfied or have no regret. Notably, postoperative pain had a more significant effect on satisfaction and regret after surgery, suggesting focused postsurgical pain management is an opportunity to substantially improve patient experiences. More research and patient education are needed for managing expectations of postoperative pain, and use of adjuncts and regional anesthesia.

Leveraging a statewide quality collaborative to understand population-level hernia care

BACKGROUND

Although ventral hernia repair (VHR) is extremely common, there is profound variation in operative technique and outcomes. This study describes the results of a statewide registry capturing hernia-specific variables to understand population-level practice patterns.

METHODS

Retrospective analysis of adult patients in a new statewide hernia registry undergoing VHR in 2020.

RESULTS

919 patients underwent VHR across 57 hospitals and 279 surgeons. Hernia width was <2 cm in 233 (25%) patients, 2-5 cm in 420 (46%) patients, 5-10 cm in 171 (19%) patients, and >10 cm in 95 (10%) patients. Mesh was used in 79% of cases and varied in use from 53% of hernias <2 cm to 95% of hernias >10 cm. The most common mesh type was synthetic non-absorbable (46%), followed by synthetic absorbable mesh (37%). The incidence of complications was significantly associated with hernia width.

CONCLUSIONS

A population-level, hernia-specific database captured operative details for 919 patients in 1 year. There was significant variation in mesh use and outcomes based on hernia size. These nuanced data may inform higher quality clinical practice.

Prevalence and Trends in Smoking Among Surgical Patients in Michigan, 2012-2019

IMPORTANCE

Surgery is a teachable moment, and smoking cessation interventions that coincide with an episode of surgical care are especially effective. Implementing these interventions at a large scale requires understanding the prevalence and characteristics of smoking among surgical patients.

OBJECTIVES

To describe the prevalence of smoking in a population of patients undergoing common surgical procedures and to identify any clinical or demographic characteristics associated with smoking.

DESIGN, SETTING, AND PARTICIPANTS

This cross-sectional study included all adult patients (aged ≥18 years) in a statewide registry who underwent general and vascular surgical procedures from 2012 to 2019 at 70 hospitals in Michigan. Data analysis was conducted from August to October 2020.

EXPOSURES

Undergoing a surgical procedure in any of the following categories: appendectomy, cholecystectomy, colon procedures, gastric or esophageal procedures, hepatopancreatobiliary procedures, hernia repair, small-bowel procedures, hysterectomy, vascular procedures, thyroidectomy, and other unspecific abdominal procedures.

MAIN OUTCOMES AND MEASURES

The prevalence of smoking prior to surgery, defined as cigarette use in the year prior to surgery, obtained from medical record review. Multivariable logistic regression was performed to analyze smoking prevalence based on insurance type and year of surgery while adjusting for demographic and clinical factors, including age, sex, race/ethnicity (determined from the medical record), insurance type, geographic region, comorbidities (ie, hypertension, diabetes, congestive heart failure, chronic obstructive pulmonary disease, chronic steroid use, and obstructive sleep apnea), American Society of Anesthesiologists classification, admission status, surgical priority, procedure type, and year of surgery.

RESULTS

From 2012 to 2019, 328 578 patients underwent surgery and were included in analysis. Mean (SD) age was 54.0 (17.0) years, and 197 501 patients (60.1%) were women. The overall prevalence of smoking was 24.1% (79 152 patients). Prevalence varied regionally from 21.5% (95% CI, 21.0%-21.9%; 6686 of 31 172 patients) in southeast Michigan to 28.0% (95% CI, 27.1%-28.9%; 2696 of 9614 patients) in northeast Michigan. When adjusting for clinical and demographic factors, there were greater odds of smoking among patients with Medicaid (odds ratio [OR], 2.75; 95% CI, 2.69-2.82) and patients without insurance (OR, 2.21; 95% CI, 2.10-2.33) compared with patients with private insurance. Among procedure categories, patients undergoing vascular surgery had greater odds of smoking (OR, 3.24; 95% CI, 3.11-3.38) than those undergoing cholecystectomy. Compared with 2012, the adjusted odds of smoking decreased significantly each year (eg, 2019: OR, 0.78; 95% CI, 0.74-0.81). In 2019, the adjusted prevalence of smoking was 22.3% (95% CI, 22.0%-22.7%) among all patients, 43.0% (95% CI, 42.4%-43.6%) among patients with Medicaid, and 36.3% (95% CI, 35.2%-37.4%) among patients without insurance.

CONCLUSIONS AND RELEVANCE

In a statewide population of surgical patients, nearly one-quarter of patients smoked cigarettes, which is higher than the national average. The prevalence of smoking was especially high among patients without insurance and among those receiving Medicaid. Given the established association between undergoing a major surgical procedure and health behavior change, targeted smoking cessation interventions at the time of surgery may be an effective strategy to improve population health, especially among at-risk patient groups.

Laparoscopic training in colorectal surgery: can we do it safely?

Objective Laparoscopic approach should be offered for most patients requiring colectomy, as it is a safe procedure, associated with shorter hospitalization, better cosmetic results, and does not affect negatively the oncological outcomes of patients with colon cancer. However, there is no consistent data on the safety of laparoscopic surgery training during residency. Therefore, the aim of this study was to assess whether or not the resident par- ticipation in laparoscopic colectomy affected the postoperative outcomes.

Methods The database of the American College of Surgeons National Surgical Quality Im- provement Program (ACS-NSQIP) was searched for patients undergoing laparoscopic col- ectomies between 2005 and 2007. We excluded patients with no data regarding whether or not there was a resident participation in the operation. The study population was divided into 2 groups (resident and nonresident), according to residents participation in the surgi- cal procedure. Perioperative variables and postoperative complications were compared be- tween groups. A multivariate analysis was performed to evaluate the association between postoperative complications and resident participation in the operation.

Results The search yielded 5,912 patients with a median age of 63 years. Of these, 3,112 (53%) were female and 3.887 (66%) had a resident involved in their operation. The resident group had a significantly longer mean operative time (163 ± 64 min vs 138 ± 58 min, p < 0.0001). Other variables did not differ significantly between groups. Moreover, multivari- ate analysis showed no association between resident participation and the occurrence of postoperative complications.

Conclusion Laparoscopic training during residency may be safely performed without threatening the patient's integrity.

Evaluation of Changes in Quality Improvement Knowledge Following a Formal Educational Curriculum Within a Statewide Learning Collaborative

OBJECTIVE

Our objectives were to (1) develop a curriculum based upon participants' needs, (2) evaluate baseline QI knowledge of the Illinois Surgical Quality Improvement Collaborative (ISQIC) members, and (3) evaluate the effectiveness of the educational curriculum.

DESIGN

The Surgeon Champion (SC), Surgical Clinical Reviewer (SCR), and QI Designee at each ISQIC hospital completed a QI curriculum containing online modules and in-person trainings. A surgical adaptation of QI-KAT, a validated QI knowledge assessment with multiple-choice and free-response sections, was administered pre- and postcurriculum. Three blinded educators scored each exam using a rubric-based scoring tool (54 total points).

SETTING

The ISQIC is a 52-hospital learning collaborative. Generally, ISQIC participants had little prior formal training or experience with quality improvement.

RESULTS

Among 52 hospitals, 144 pretests and 112 post-tests were collected. Mean scores increased from 66% (35.6 points) to 77% (41.6 points; p < 0.001). Across all hospitals, all participant groups scored higher on the post-test (SCs 15%, SCRs 21%, QI Designees 17%). There was no significant difference in post-test mean scores among different team members: SCs 44 points, SCRs 42 points, QI Designees 44 points, (p = 0.76). When the post-test scores were aggregated at the hospital level, hospitals with new surgical QI programs improved more than hospitals with established programs (new 18%, established 11%, p < 0.05).

CONCLUSIONS

QI knowledge significantly improved after completion of the ISQIC curriculum. These data support the value of formalized curricula to rapidly advance QI knowledge and application skills as a foundation for implementing QI initiatives.

Translating Hand Surgery Evidence to Policy and Practice

Hand surgery researchers should focus on developing high-quality evidence to support the development of health policies affecting surgical care. Policy-makers and leaders of national hand societies can help reduce the variation of care for patients receiving hand surgery by incorporating evidence into guidelines and policies. Comprehensive guidelines for perioperative care help encourage the translation of evidence into practice. Moreover, the identification of institutional-level barriers and facilitators of integration ensures the successful implementation of hand surgery-specific programs. The development of robust metrics to evaluate the effect of policy on practice helps examine the feasibility of clinical guidelines.

Quality Measures in Postmastectomy Breast Reconstruction: Identifying Metrics to Improve Care

BACKGROUND

Specific measures tailored to the properties of individual procedures will ensure the appropriate evaluation of quality. Because postmastectomy breast reconstruction (PMBR) is becoming increasingly common, a review of the literature is timely to identify potential breast reconstruction-specific measures that can be applied by institutions and national healthcare organizations to improve quality.

METHODS

We searched PubMed and Embase for studies examining the quality of care for patients undergoing PMBR. Data extracted from the articles include basic study characteristics, the number of quality metrics, type of quality metric (defined by Donabedian model), and the domain of quality (defined by the National Academy of Medicine).

RESULTS

A total of 2,158 articles were identified in the initial search, and 440 studies were included for data extraction. The most common type of quality measure was outcome measures (91%), and the least common measure was structure measures (1%). The most common metrics were operative time (41%), hospital type (28%), and aspects of the patient-provider interactions (20%). Additionally, we found that timeliness and equity were least common among the 6 National Academy of Medicine domains.

CONCLUSIONS

We identified metrics utilized in the PMBR, some of which can be further investigated through high-level evidence studies and incorporated into policy. Because many factors influence surgical outcomes and breast reconstruction is driven by patient preferences, an inclusion of structure, process, and outcome metrics will help improve care for this patient population. Moreover, nonpunitive initiatives, specifically quality collaboratives, may provide an avenue to improve care quality without compromising patient safety.

Baseline Performance of Real-World Clinical Practice Within a Statewide Emergency Medicine Quality Network: The Michigan Emergency Department Improvement Collaborative (MEDIC)

STUDY OBJECTIVE

Large-scale quality and performance measurement across unaffiliated hospitals is an important strategy to drive practice change. The Michigan Emergency Department Improvement Collaborative (MEDIC), established in 2015, has baseline performance data to identify practice variation across 15 diverse emergency departments (EDs) on key emergency care quality indicators.

METHODS

MEDIC is a unique physician-led partnership supported by a major third-party payer. Member sites contribute electronic health record data and trained abstractors add supplementary data for eligible cases. Quality measures include computed tomography (CT) appropriateness for minor head injury, using the Canadian CT Head Rule for adults and Pediatric Emergency Care Applied Network rules for children; chest radiograph use for children with asthma, bronchiolitis, and croup; and diagnostic yield of CTs for suspected pulmonary embolism. Baseline performance was established with statistical process control charts.

RESULTS

From June 1, 2016, to October 31, 2017, the MEDIC registry contained 1,124,227 ED visits, 23.2% for children (<18 years). Overall baseline performance included the following: 40.9% of adult patients with minor head injury (N=11,857) had appropriate CTs (site range 24.3% to 58.6%), 10.3% of pediatric minor head injury cases (N=11,183) exhibited CT overuse (range 5.8% to 16.8%), 38.1% of pediatric patients with a respiratory condition (N=18,190) received a chest radiograph (range 9.0% to 62.1%), and 8.7% of pulmonary embolism CT results (N=16,205) were positive (range 7.5% to 14.3%).

CONCLUSION

Performance varied greatly, with demonstrated opportunity for improvement. MEDIC provides a robust platform for emergency physician engagement across ED practice settings to improve care and is a model for other states.

Patient Demographic and Surgical Factors that Affect Completion of Patient-Reported Outcomes 90 Days and 1 Year After Spine Surgery: Analysis from the Michigan Spine Surgery Improvement Collaborative (MSSIC)

BACKGROUND

The Michigan Spine Surgery Improvement Collaborative is a statewide multicenter quality improvement registry. Because missing data can affect registry results, we used MSSIC to find demographic and surgical characteristics that affect the completion of patient-reported outcomes (PROs) at 90 days and 1 year.

METHODS

A total of 24,404 patients who had lumbar surgery (17,813 patients) or cervical surgery (6591 patients) were included. Multivariate logistic regression models of patient disease were constructed to identify risk factors for failure to complete scheduled PRO surveys.

RESULTS

Patients ≥65 years old and female patients were both more likely to respond at 90 days and 1 year. Increasing education was associated with greater response rate at 90 days and 1 year. Whites and African Americans had no differences in response rates. Calling provided the highest response rate at 90 days and 1 year. For cervical spine patients, only discharge to rehabilitation increased completion rates, at 90 days but not 1 year. For lumbar spine patients, spondylolisthesis or stenosis (vs. herniated disc) had a greater response rate at 1 year. Patients with leg (vs. back) pain had a greater response only at 1 year. Patients with multilevel surgery had an increased response at 1 year. Patients who underwent fusion were more likely to respond at 90 days, but not 1 year. Discharge to rehabilitation increased response at 90 days and 1 year.

CONCLUSIONS

A multivariate analysis from a multicenter prospective database identified surgical factors that affect PRO follow-up, up to 1 year. This information can be helpful for imputing missing PRO data and could be used to strengthen data derived from large prospective databases.

Adverse events and their risk factors 90 days after cervical spine surgery: analysis from the Michigan Spine Surgery Improvement Collaborative

OBJECTIVE

The Michigan Spine Surgery Improvement Collaborative (MSSIC) is a statewide, multicenter quality improvement initiative. Using MSSIC data, the authors sought to identify 90-day adverse events and their associated risk factors (RFs) after cervical spine surgery.

METHODS

A total of 8236 cervical spine surgery cases were analyzed. Multivariable generalized estimating equation regression models were constructed to identify RFs for adverse events; variables tested included age, sex, diabetes mellitus, disc herniation, foraminal stenosis, central stenosis, American Society of Anesthesiologists Physical Classification System (ASA) class > II, myelopathy, private insurance, anterior versus posterior approach, revision procedures, number of surgical levels, length of procedure, blood loss, preoperative ambulation, ambulation day of surgery, length of hospital stay, and discharge disposition.

RESULTS

Ninety days after cervical spine surgery, adverse events identified included radicular findings (11.6%), readmission (7.7%), dysphagia requiring dietary modification (feeding tube or nothing by mouth [NPO]) (6.4%), urinary retention (4.7%), urinary tract infection (2.2%), surgical site hematoma (1.1%), surgical site infection (0.9%), deep vein thrombosis (0.7%), pulmonary embolism (0.5%), neurogenic bowel/bladder (0.4%), myelopathy (0.4%), myocardial infarction (0.4%), wound dehiscence (0.2%), claudication (0.2%), and ileus (0.2%). RFs for dysphagia included anterior approach (p < 0.001), fusion procedures (p = 0.030), multiple-level surgery when considering anterior procedures only (p = 0.037), and surgery duration (p = 0.002). RFs for readmission included ASA class > II (p < 0.001), while preoperative ambulation (p = 0.001) and private insurance (p < 0.001) were protective. RFs for urinary retention included increasing age (p < 0.001) and male sex (p < 0.001), while anterior-approach surgery (p < 0.001), preoperative ambulation (p = 0.001), and ambulation day of surgery (p = 0.001) were protective. Preoperative ambulation (p = 0.010) and anterior approach (p = 0.002) were protective of radicular findings.

CONCLUSIONS

A multivariate analysis from a large, multicenter, prospective database identified the common adverse events after cervical spine surgery, along with their associated RFs. This information can lead to more informed surgeons and patients. The authors found that early mobilization after cervical spine surgery has the potential to significantly decrease adverse events.

Association of Opioid Prescribing With Opioid Consumption After Surgery in Michigan

Importance

There is growing evidence that opioids are overprescribed following surgery. Improving prescribing requires understanding factors associated with opioid consumption.

Objective

To describe opioid prescribing and consumption for a variety of surgical procedures and determine factors associated with opioid consumption after surgery.

Design, Setting, and Participants

A retrospective, population-based analysis of the quantity of opioids prescribed and patient-reported opioid consumption across 33 health systems in Michigan, using a sample of adults 18 years and older undergoing surgery. Patients were included if they were prescribed an opioid after surgery. Surgical procedures took place between January 1, 2017, and September 30, 2017, and were included if they were performed in at least 25 patients.

Exposures

Opioid prescription size in the initial postoperative prescription.

Main Outcomes and Measures

Patient-reported opioid consumption in oral morphine equivalents. Linear regression analysis was used to calculate risk-adjusted opioid consumption with robust standard errors.

Results

In this study, 2392 patients (mean age, 55 years; 1353 women [57%]) underwent 1 of 12 surgical procedures. Overall, the quantity of opioid prescribed was significantly higher than patient-reported opioid consumption (median, 30 pills; IQR, 27-45 pills of hydrocodone/acetaminophen, 5/325 mg, vs 9 pills; IQR, 1-25 pills; P < .001). The quantity of opioid prescribed had the strongest association with patient-reported opioid consumption, with patients using 0.53 more pills (95% CI, 0.40-0.65; P < .001) for every additional pill prescribed. Patient-reported pain in the week after surgery was also significantly associated with consumption but not as strongly as prescription size. Compared with patients reporting no pain, patients used a mean (SD) 9 (1) more pills if they reported moderate pain and 16 (2) more pills if they reported severe pain (P < .001). Other significant risk factors included history of tobacco use, American Society of Anesthesiologists class, age, procedure type, and inpatient surgery status. After adjusting for these risk factors, patients in the lowest quintile of opioid prescribing had significantly lower mean (SD) opioid consumption compared with those in the highest quintile (5 [2] pills vs 37 [3] pills; P < .001).

Conclusions and Relevance

The quantity of opioid prescribed is associated with higher patient-reported opioid consumption. Using patient-reported opioid consumption to develop better prescribing practices is an important step in combating the opioid epidemic.

Accelerating surgical quality improvement in Ontario through a regional collaborative: a quality-improvement study

BACKGROUND

The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) collaborative in Ontario, the Ontario Surgical Quality Improvement Network (ON-SQIN), was launched in January 2015. We describe its approaches to support surgical quality improvement and examine its early impact on member hospitals.

METHODS

All Ontario hospitals that participated in the ON-SQIN and NSQIP were included in this quality-improvement study. The primary intervention was the introduction of the ON-SQIN, and the secondary interventions included a community of practice and access to quality-improvement resources and tools. Outcome measures included the level of quality-improvement capacity, collaborative-wide aggregate data on postoperative complications, and self-reported rates of surgical site and urinary tract infections.

RESULTS

Eighteen hospitals that enrolled in the ON-SQIN in 2015 reported an increase in their capacity for quality improvement after 18 months. Analysis of the collaborative-wide aggregate data in a 6-month period (14 748 surgical cases) revealed a substantial reduction of acute renal failure (relative risk 0.48, 95% confidence interval 0.25-0.95) and urinary tract infection (relative risk 0.77, 95% confidence interval 0.61-0.97). Most hospitals that targeted prevention of surgical site infection and urinary tract infection reported reduction of these occurrences during a 1-year period.

INTERPRETATION

The ON-SQIN supported the uptake of the NSQIP in Ontario hospitals and promoted targeted surgical quality-improvement initiatives, resulting in increased quality-improvement capacity and development of the community of practice. Furthermore, our early experience suggests that improvements in surgical care are being realized.

The South Carolina Surgical Quality Collaborative: A New Effort to Improve Surgical Outcomes in South Carolina

Regional surgical quality Collaboratives are improving surgical quality and cutting costs by building regional relationships that leverage information sharing to improve outcomes. The South Carolina Surgical Quality Collaborative (SCSQC) is a new regional surgical quality Collaborative focused on improving general surgery outcomes in South Carolina. It is a joint effort which brings together the skills and resources of Health Sciences South Carolina, the South Carolina Hospital Association, and the Blue Cross Blue Shield of SC Foundation to create a web-based data collection system to provide real-time outcomes data to participating surgeons, and establishing a supportive network for sharing best practices and promoting data driven quality improvement. Members of the SCSQC abstracted more than 8000 general surgery cases from eight participating hospitals in its first year. These facilities are spread across the state of South Carolina and range from large academic referral centers to small community hospitals. The resulting data should be representative of much of the surgical care provided in South Carolina. Monthly conference calls and quarterly face-to-face meetings occur with site Surgeon Leads, site Surgical Clinical Quality Reviewer, and Collaborative leaders. Each site is pursuing a quality improvement project addressing issues identified from analysis of their initial data. Early results on these efforts are encouraging. The SCSQC is a new regional surgical quality Collaborative, which leverages multiple state resources, builds on the successes of similar Collaboratives in Michigan and Tennessee, with the goal to improve the quality and value of general surgical care for South Carolinians.

Are quality improvement collaboratives effective? A systematic review

Background

Quality improvement collaboratives (QIC) have proliferated internationally, but there is little empirical evidence for their effectiveness.

Method

We searched Medline, Embase, CINAHL, PsycINFO and the Cochrane Library databases from January 1995 to December 2014. Studies were included if they met the criteria for a QIC intervention and the Cochrane Effective Practice and Organisation of Care (EPOC) minimum study design characteristics for inclusion in a review. We assessed study bias using the EPOC checklist and the quality of the reported intervention using a subset of SQUIRE 1.0 standards.

Results

Of the 220 studies meeting QIC criteria, 64 met EPOC study design standards for inclusion. There were 10 cluster randomised controlled trials, 24 controlled before-after studies and 30 interrupted time series studies. QICs encompassed a broad range of clinical settings, topics and populations ranging from neonates to the elderly. Few reports fully described QIC implementation and methods, intensity of activities, degree of site engagement and important contextual factors. By care setting, an improvement was reported for one or more of the study’s primary effect measures in 83% of the studies (32/39 (82%) hospital based, 17/20 (85%) ambulatory care, 3/4 nursing home and a sole ambulance QIC). Eight studies described persistence of the intervention effect 6 months to 2 years after the end of the collaborative. Collaboratives reporting success generally addressed relatively straightforward aspects of care, had a strong evidence base and noted a clear evidence-practice gap in an accepted clinical pathway or guideline.

Conclusions

QICs have been adopted widely as an approach to shared learning and improvement in healthcare. Overall, the QICs included in this review reported significant improvements in targeted clinical processes and patient outcomes. These reports are encouraging, but most be interpreted cautiously since fewer than a third met established quality and reporting criteria, and publication bias is likely.

Predictors of micro-costing components in liver transplantation

OBJECTIVES:

Although liver transplantation procedures are common and highly expensive, their cost structure is still poorly understood. This study aimed to develop models of micro-costs among patients undergoing liver transplantation procedures while comparing the role of individual clinical predictors using tree regression models.

METHODS:

We prospectively collected micro-cost data from patients undergoing liver transplantation in a tertiary academic center. Data collection was conducted using an Intranet registry integrated into the institution's database for the storing of financial and clinical data for transplantation cases.

RESULTS:

A total of 278 patients were included and accounted for 300 procedures. When evaluating specific costs for the operating room, intensive care unit and ward, we found that in all of the sectors but the ward, human resources were responsible for the highest costs. High cost supplies were important drivers for the operating room, whereas drugs were among the top four drivers for all sectors. When evaluating the predictors of total cost, a MELD score greater than 30 was the most important predictor of high cost, followed by a Donor Risk Index greater than 1.8.

CONCLUSION:

By focusing on the highest cost drivers and predictors, hospitals can initiate programs to reduce cost while maintaining high quality care standards.

Moving the needle toward high-quality pediatric surgical care: How can we achieve this goal through prioritization, measurement and more effective collaboration?

Over the past decade, the American College of Surgeons Pediatric National Surgical Quality Improvement Program (NSQIP-Pediatric) has greatly improved upon our ability to measure, benchmark and compare outcomes as they relate to pediatric surgical care. Several factors have served to mold the program's evolution and data collection paradigm over time. These have included a broader understanding of what quality measures should be captured and compared from the perspectives of different stakeholders, identification of conditions where quality and process improvement efforts may have the greatest relative impact from a public health perspective, and increasing evidence in support of collaborative networks to accelerate quality improvement through the dissemination of best practices. The purpose of today's lecture is to review these factors in the context of a comprehensive road map for optimizing the quality of pediatric surgical care, and the role that NSQIP-Pediatric has and will continue to play as the foundation supporting this road map.

Strategies for handling missing clinical data for automated surgical site infection detection from the electronic health record

Proper handling of missing data is important for many secondary uses of electronic health record (EHR) data. Data imputation methods can be used to handle missing data, but their use for analyzing EHR data is limited and specific efficacy for postoperative complication detection is unclear. Several data imputation methods were used to develop data models for automated detection of three types (i.e., superficial, deep, and organ space) of surgical site infection (SSI) and overall SSI using American College of Surgeons National Surgical Quality Improvement Project (NSQIP) Registry 30-day SSI occurrence data as a reference standard. Overall, models with missing data imputation almost always outperformed reference models without imputation that included only cases with complete data for detection of SSI overall achieving very good average area under the curve values. Missing data imputation appears to be an effective means for improving postoperative SSI detection using EHR clinical data.

Evaluation of hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program

BACKGROUND

The American College of Surgeons National Surgical Quality Improvement Program is well recognized in surgical quality measurement and is used widely in research. Recent calls to make it a platform for national public reporting and pay-for-performance initiatives highlight the importance of understanding which types of hospitals elect to participate in the program. Our objective was to compare characteristics of hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program to characteristics of nonparticipating US hospitals.

METHODS

The 2013 American Hospital Association and Centers for Medicare & Medicaid Services Healthcare Cost Report Information System datasets were used to compare characteristics and operating margins of hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program to those of nonparticipating hospitals.

RESULTS

Of 3,872 general medical and surgical hospitals performing inpatient surgery in the United States, 475 (12.3%) participated in the American College of Surgeons National Surgical Quality Improvement Program. Participating hospitals performed 29.0% of all operations in the United States. Compared with nonparticipating hospitals, American College of Surgeons National Surgical Quality Improvement Program hospitals had a higher mean annual inpatient surgical case volume (6,426 vs 1,874; P < .001) and a larger mean number of hospital beds (420 vs 167; P < .001); participating hospitals were more often teaching hospitals (35.2% vs 4.1%; P < .001), had more quality-related accreditations (P < .001), and had higher mean operating margins (P < .05). States with the highest proportions of hospitals participating in the American College of Surgeons National Surgical Quality Improvement Program had established surgical quality improvement collaboratives.

CONCLUSION

The American College of Surgeons National Surgical Quality Improvement Program hospitals are large teaching hospitals with more quality-related accreditations and financial resources. These findings should be considered when reviewing research studies using the American College of Surgeons National Surgical Quality Improvement Program data, and the findings reinforce that efforts are needed to facilitate participation in surgical quality improvement by all hospital types.

Prostate Cancer Registries: Current Status and Future Directions

CONTEXT

Disease-specific registries that enroll a considerable number of patients play a major role in prostate cancer (PCa) research.

OBJECTIVE

To evaluate available registries, describe their strengths and limitations, and discuss the potential future role of PCa registries in outcomes research.

EVIDENCE ACQUISITION

We performed a literature review of the Medline, Embase, and Web of Science databases. The search strategy included the terms prostate cancer, outcomes, statistical approaches, population-based cohorts, registries of outcomes, and epidemiological studies, alone or in combination. We limited our search to studies published between January 2005 and January 2015.

EVIDENCE SYNTHESIS

Several population-based and prospective disease-specific registries are currently available for prostate cancer. Studies performed using these data sources provide important information on incidence and mortality, disease characteristics at presentation, risk factors, trends in utilization of health care services, disparities in access to treatment, quality of care, long-term oncologic and health-related quality of life outcomes, and costs associated with management of the disease. Although data from these registries have some limitations, statistical methods are available that can address certain biases and increase the internal and external validity of such analyses. In the future, improvements in data quality, collection of tissue samples, and the availability of data feedback to health care providers will increase the relevance of studies built on population-based and disease-specific registries.

CONCLUSIONS

The strengths and limitations of PCa registries should be carefully considered when planning studies using these databases. Although randomized controlled trials still provide the highest level of evidence, large registries play an important and growing role in advancing PCa research and care.

PATIENT SUMMARY

Several population-based and prospective disease-specific registries for prostate cancer are currently available. Analyses of data from these registries yield information that is clinically relevant for the management of patients with prostate cancer.

Reducing healthcare costs facilitated by surgical auditing: a systematic review

BACKGROUND

Surgical auditing has been developed in order to benchmark and to facilitate quality improvement. The aim of this review is to determine if auditing combined with systematic feedback of information on process and outcomes of care results in lower costs of surgical care.

METHOD

A systematic search of published literature before 21-08-2013 was conducted in Pubmed, Embase, Web of Science, and Cochrane Library. Articles were selected if they met the inclusion criteria of describing a surgical audit with cost-evaluation.

RESULTS

The systematic search resulted in 3608 papers. Six studies were identified as relevant, all showing a positive effect of surgical auditing on quality of healthcare and therefore cost savings was reported. Cost reductions ranging from $16 to $356 per patient were seen in audits evaluating general or vascular procedures. The highest potential cost reduction was described in a colorectal surgical audit (up to $1,986 per patient).

CONCLUSIONS

All six identified articles in this review describe a reduction in complications and thereby a reduction in costs due to surgical auditing. Surgical auditing may be of greater value when high-risk procedures are evaluated, since prevention of adverse events in these procedures might be of greater clinical and therefore of greater financial impact.

IMPLICATION OF KEY FINDINGS

This systematic review shows that surgical auditing can function as a quality instrument and therefore as a tool to reduce costs. Since evidence is scarce so far, further studies should be performed to investigate if surgical auditing has positive effects to turn the rising healthcare costs around. In the future, incorporating (actual) cost analyses and patient-related outcome measures would increase the audits' value and provide a complete overview of the value of healthcare.

The Michigan Spine Surgery Improvement Collaborative: a statewide Collaborative Quality Initiative

OBJECT

Given the scrutiny of spine surgery by policy makers, spine surgeons are motivated to demonstrate and improve outcomes, by determining which patients will and will not benefit from surgery, and to reduce costs, often by reducing complications. Insurers are similarly motivated. In 2013, Blue Cross Blue Shield of Michigan (BCBSM) and Blue Care Network (BCN) established the Michigan Spine Surgery Improvement Collaborative (MSSIC) as a Collaborative Quality Initiative (CQI). MSSIC is one of the newest of 21 other CQIs that have significantly improved—and continue to improve—the quality of patient care throughout the state of Michigan.

METHODS

MSSIC focuses on lumbar and cervical spine surgery, specifically indications such as stenosis, disk herniation, and degenerative disease. Surgery for tumors, traumatic fractures, deformity, scoliosis, and acute spinal cord injury are currently not within the scope of MSSIC. Starting in 2014, MSSIC consisted of 7 hospitals and in 2015 included another 15 hospitals, for a total of 22 hospitals statewide. A standardized data set is obtained by data abstractors, who are funded by BCBSM/BCN. Variables of interest include indications for surgery, baseline patient-reported outcome measures, and medical history. These are obtained within 30 days of surgery. Outcome instruments used include the EQ-5D general health state score (0 being worst and 100 being the best health one can imagine) and EQ-5D-3 L. For patients undergoing lumbar surgery, a 0 to 10 numeric rating scale for leg and back pain and the Oswestry Disability Index for back pain are collected. For patients undergoing cervical surgery, a 0 to 10 numeric rating scale for arm and neck pain, Neck Disability Index, and the modified Japanese Orthopaedic Association score are collected. Surgical details, postoperative hospital course, and patient-reported outcome measures are collected at 90-day, 1-year, and 2-year intervals.

RESULTS

As of July 1, 2015, a total of 6397 cases have been entered into the registry. This number reflects 4824 eligible cases with confirmed surgery dates. Of these 4824 eligible cases, 3338 cases went beyond the 120-day window and were considered eligible for the extraction of surgical details, 90-day outcomes, and adverse events. Among these 3338 patients, there are a total of 2469 lumbar cases, 862 cervical cases, and 7 combined procedures that were entered into the registry.

CONCLUSIONS

In addition to functioning as a registry, MSSIC is also meant to be a platform for quality improvement with the potential for future initiatives and best practices to be implemented statewide in order to improve quality and lower costs. With its current rate of recruitment and expansion, MSSIC will provide a robust platform as a regional prospective registry. Its unique funding model, which is supported by BCBSM/BCN, will help ensure its longevity and viability, as has been observed in other CQIs that have been active for several years.
