RESUMEN
Importance: Acute urinary retention (UR) is common, yet variations in diagnosis and management can lead to inappropriate catheterization and harm. Objective: To develop an algorithm for screening and management of UR among adult inpatients. Design, Setting, and Participants: In this mixed-methods study using the RAND/UCLA Appropriateness Method and qualitative interviews, an 11-member multidisciplinary expert panel of nurses and physicians from across the US used a formal multi-round process from March to May 2015 to rate 107 clinical scenarios involving diagnosis and management of adult UR in postoperative and medical inpatients. The panel ratings informed the first algorithm draft. Semistructured interviews were conducted from October 2020 to May 2021 with 33 frontline clinicians-nurses and surgeons from 5 Michigan hospitals-to gather feedback and inform algorithm refinements. Main Outcomes and Measures: Panelists categorized scenarios assessing when to use bladder scanners, catheterization at various scanned bladder volumes, and choice of catheterization modalities as appropriate, inappropriate, or uncertain. Next, qualitative methods were used to understand the perceived need, usability, and potential algorithm uses. Results: The 11-member expert panel (10 men and 1 woman) used the RAND/UCLA Appropriateness Method to develop a UR algorithm including the following: (1) bladder scanners were preferred over catheterization for UR diagnosis in symptomatic patients or starting as soon as 3 hours since last void if asymptomatic, (2) bladder scanner volumes appropriate to prompt catheterization were 300 mL or greater in symptomatic patients and 500 mL or greater in asymptomatic patients, and (3) intermittent was preferred to indwelling catheterization for managing lower bladder volumes. Interview findings were organized into 3 domains (perceived need, feedback on algorithm, and implementation suggestions). The 33 frontline clinicians (9 men and 24 women) who reviewed the algorithm reported that an evidence-based protocol (1) was needed and could be helpful to clinicians, (2) should be simple and graphically appealing to improve rapid clinician review, and (3) should be integrated within the electronic medical record and prominently displayed in hospital units to increase awareness. The draft algorithm was iteratively refined based on stakeholder feedback. Conclusions and Relevance: In this study using a systematic, multidisciplinary, evidence- and expert opinion-based approach, a UR evaluation and catheterization algorithm was developed to improve patient safety by increasing appropriate use of bladder scanners and catheterization. This algorithm addresses the need for practical guidance to manage UR among adult inpatients.

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.

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.

BACKGROUND: Annually, more than 2 million patients are admitted with emergency general surgery (EGS) conditions. Emergency general surgery cases comprise 11% of all general surgery operations, yet account for 47% of mortalities and 28% of complications. Using the statewide general surgery Michigan Surgical Quality Collaborative (MSQC) data, we previously confirmed that wide variations in EGS outcomes were unrelated to case volume/complexity. We assessed whether patient care model (PCM) affected EGS outcomes. STUDY DESIGN: There were 34 hospitals that provided data for PCM, resources, surgeon practice patterns, and comprehensive MSQC patient data from January 1, 2008 to December 31, 2016 (general surgery cases = 126,494; EGS cases = 39,023). Risk and reliability adjusted outcomes were determined using hierarchical multivariable logistic regression analysis with multiple clinical covariates and PCM. RESULTS: The general surgery service (GSS) model was more common (73%) than acute care surgery (ACS, 27%). Emergency general surgery 30-day mortality was 4.1% (intestinal resections 11.6%). The ACS model was associated with a reduction of 31% in mortality (odds ratio [OR] 0.69; 95% CI 0.52-0.92] for EGS cases, related to decreased mortality in the intestinal resection cohort (8.5% ACS vs 12% GSS, p < 0.0001). Morbidity in EGS was 17.4% (9.7% elective); highest (40%) in intestinal resection, and PCM did not affect morbidity. We identified specific variables for an optimal EGS risk adjustment model. CONCLUSIONS: This is the first multi-institutional study to identify that an ACS model is associated with a significant 31% mortality reduction in EGS using prospectively collected, clinically obtained, research-quality collaborative data. We identified that new risk adjustment models are necessary for EGS outcomes evaluations.

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.

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.

BACKGROUND: The Hospital Acquired Condition Reduction Program (HACRP) is a national pay-for-performance program that includes a measure of surgical site infection (SSI) after hysterectomy and colectomy. This study compares the HACRP SSI measure with other published methods. STUDY DESIGN: This was a retrospective cohort study from the Michigan Surgical Quality Collaborative (MSQC). The outcome was 30-day, adjusted deep and organ space SSI ("complex SSI"). Observed-to-expected ratios of complex SSI for each hospital were calculated using HACRP, National Healthcare Safety Network (NHSN), and MSQC methodologies. C-statistics were compared between models. Hospital rankings were compared, and ladder plots show changes in hospitals' HACRP scores that derive from each algorithm. RESULTS: Complex SSI occurred in 1.1% (190 of 16,672) of hysterectomies and 4.8% (n = 514 of 10,725) of colectomies. The HACRP risk-adjustment model for hysterectomy had a C-statistic of 0.55, significantly lower than NHSN (0.61, p = 0.0461) or MSQC models (0.77, p < 0.0001). For colectomy, C-statistics were 0.57, 0.66 (p < 0.0001) and 0.73 (p < 0.0001), respectively. For both operations, there were 5 high-outlier hospitals using HACRP, but fewer (4 or 3) using the other methods. Most hospitals in the bottom quartile were not statistical outliers, but would be flagged under HACRP. More than 50% of hospitals changed ranking position between models, which would result in different scores under HACRP. CONCLUSIONS: This study showed that the HACRP SSI measure unfairly places hospitals at risk for financial penalties that are not statistical outliers. Policy makers need to weigh the burden of data collection and the accuracy needed to identify hospitals for financial reward or penalty.

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.

OBJECTIVE: Surgery remains the cornerstone therapy for colorectal cancer (CRC). This study assesses CRC quality measures for surgical cases in Michigan. METHODS: In this retrospective cohort study, processes of care and outcomes for CRC resection cases were abstracted in 30 hospitals in the Michigan Surgical Quality Collaborative (2014-2015). Measures were case-mix and reliability adjusted, using logistic regression models. RESULTS: For 871 cases (640 colon cancer, 231 rectal cancer), adjusted morbidity (27.4%) and mortality rates (1.5%) were low. Adjusted process measures showed gaps in quality of care. Mesorectal excision was documented in 59.4% of rectal cancer (RC) cases, 65% of RC cases had sphincter preserving surgery, 18.7% of cases had < 12 lymph nodes examined, 7.9% had a positive margin, 52.1% of stage II/III RC cases had neoadjuvant therapy, and 36% of ostomy cases had site marking. CONCLUSION: This study finds gaps in quality of care measures for CRC, suggesting opportunity for regional quality improvement.

BACKGROUND: Emergency general surgery is associated with high morbidity and mortality but has seldom been targeted for practice improvement. The goal of this study was to determine whether perioperative practices vary among surgeons for emergency Hartmann's procedures and whether perioperative care practices are associated with hospitals' complication rates. MATERIALS AND METHODS: We conducted a survey of surgeons at 27 Michigan hospitals. Questionnaires focused on preoperative, intraoperative, and postoperative care practices. Hospitals were divided into quartiles of risk-adjusted complication rates. Responses of surgeons at hospitals with the lowest complication rates were compared to those with the highest, to determine whether there were systematic differences. Qualitative content analysis was performed for open-ended questions. RESULTS: A total of 106 surgeons returned questionnaires (response rate 49%). We identified variation in use of bowel preparation, ostomy site marking, rectal stump management, ostomy protrusion, skin closure method, antibiotics duration, and ambulation/physical therapy practices. Surgeons from hospitals with low complication rates were more likely to use a clean instrument tray during wound closure (61% versus 11%, P = 0.001) and reported greater use of laparoscopic lavage without resection for emergency diverticulitis cases (31% versus 6%, P = 0.05). Surgeons in the lower complication rate hospitals listed more modifiable care factors in their open-ended responses to questions about reasons for complications. CONCLUSIONS: Surgeons' practices vary for emergency Hartmann's procedure. This study serves as a proof of concept that studying surgeons' practices is feasible within a quality collaborative setting. Such data can be used to generate testable hypotheses for performance improvement aimed in high-risk, emergency surgery.

Robotic colorectal surgery has been shown to have lower rates of unplanned conversion to open surgery when compared to laparoscopic surgery. Risk factors associated with conversion from robotic to open colectomy and comparisons of the risk factors between robotic and laparoscopic approaches have not been previously reported. Patients who underwent elective laparoscopic and robotic colorectal surgeries between July 1, 2012 and April 28, 2015, were identified in the Michigan Surgical Quality Collaborative registry. Candidate covariates were identified, and hierarchical logistic regression models were used to identify risk factors for conversion. There were 4796 cases that met study inclusion criteria. Conversion was required in 18.2 % of laparoscopic and 7.7 % of robotic cases (p < 0.0001). Risk factors for conversion in the laparoscopic group included the following: moderate/severe adhesions, obesity, colorectal cancer, hypertension, rectal operations, urgent priority, and tobacco use. Risk factors for conversion in the robotic group included the following: severe adhesions, bleeding disorder, presence of cancer, cirrhosis, and use of statins. Higher surgeon volume was protective in both groups. Conversion rates are lower for robotic than for laparoscopic colorectal surgery with fewer predictors of conversion. Recognition of factors predicting conversion may allow surgeons to choose an operative approach that optimizes the benefits of the available technologies.

BACKGROUND: Current data addressing the role of robotic surgery for the management of colorectal disease are primarily from single-institution and case-matched comparative studies as well as administrative database analyses. The purpose of this study was to compare minimally invasive surgery outcomes using a large regional protocol-driven database devoted to surgical quality, improvement in patient outcomes, and cost-effectiveness. METHODS: This is a retrospective cohort study from the prospectively collected Michigan Surgical Quality Collaborative registry designed to compare outcomes of patients who underwent elective laparoscopic, hand-assisted laparoscopic, and robotic colon and rectal operations between July 1, 2012 and October 7, 2014. We adjusted for differences in baseline covariates between cases with different surgical approaches using propensity score quintiles modeled on patient demographics, general health factors, diagnosis, and preoperative co-morbidities. The primary outcomes were conversion rates and hospital length of stay. Secondary outcomes included operative time, and postoperative morbidity and mortality. RESULTS: A total of 2735 minimally invasive colorectal operations met inclusion criteria. Conversion rates were lower with robotic as compared to laparoscopic operations, and this was statistically significant for rectal resections (colon 9.0 vs. 16.9%, p < 0.06; rectum 7.8 vs. 21.2%, p < 0.001). The adjusted length of stay for robotic colon operations (4.00 days, 95% CI 3.63-4.40) was significantly shorter compared to laparoscopic (4.41 days, 95% CI 4.17-4.66; p = 0.04) and hand-assisted laparoscopic cases (4.44 days, 95% CI 4.13-4.78; p = 0.008). There were no significant differences in overall postoperative complications among groups. CONCLUSIONS: When compared to conventional laparoscopy, the robotic platform is associated with significantly fewer conversions to open for rectal operations, and significantly shorter length of hospital stay for colon operations, without increasing overall postoperative morbidity. These findings and the recent upgrades in minimally invasive technology warrant continued evaluation of the role of the robotic platform in colorectal surgery.

BACKGROUND: Nonsteroidal anti-inflammatory drugs have become an important component of narcotic-sparing postoperative pain management protocols. However, conflicting evidence exists regarding the adverse association of nonsteroidal anti-inflammatory drug use with intestinal anastomotic healing in colorectal surgery. OBJECTIVE: This study compares patients receiving nonsteroidal anti-inflammatory drugs on postoperative day 1 with patients who did not receive nonsteroidal anti-inflammatory drugs with regard to the occurrence of anastomotic leaks. DESIGN: This is a retrospective study from a protocol-driven prospectively collected statewide database. A propensity score model was used to adjust for differences between the groups in patient demographics, characteristics, comorbidities, and laboratory values. SETTINGS: The multicenter data set used in this analysis represents a variety of academic and community hospitals within the state of Michigan from July 2012 through February 2014. PATIENTS: Nonpregnant patients over the age of 18 who underwent colon and rectal surgery with bowel anastomosis were selected. MAIN OUTCOME MEASURES: Occurrence of anastomotic leak, composite surgical site infection, sepsis, and death within 30 days of surgery were the primary outcomes measured. RESULTS: A total of 4360 patients met inclusion criteria, of which 1297 (29.7%) received nonsteroidal anti-inflammatory drugs and 3063 (70.3%) did not receive nonsteroidal anti-inflammatory drugs. There was no statistically significant difference between the 2 groups in the proportion of cases with anastomotic leak (OR, 1.33; CI, 0.86-2.05; p = 0.20), composite surgical site infection (OR, 1.26; CI, 0.96-1.66; p = 0.09), or death within 30 days (OR, 0.58; CI, 0.28-1.19; p = 0.14). There was a significantly greater risk of sepsis for patients given nonsteroidal anti-inflammatory drugs than for those patients not given nonsteroidal anti-inflammatory drugs (OR, 1.47; CI, 1.05-2.06; p = 0.03). LIMITATIONS: This is a nonrandomized study performed retrospectively, and it is based on data collected only within a subset of hospitals in the state of Michigan. CONCLUSIONS: No statistically significant increase in the proportion of patients with anastomotic leak was observed when prescribing nonsteroidal anti-inflammatory drugs for analgesia in the early postoperative period for patients undergoing elective colorectal surgery. Unexpectedly, there was an increased risk of sepsis that warrants further investigation (see video, Supplemental Digital Content 1, http://links.lww.com/DCR/A192, for a synopsis of this study).

PURPOSE: Our objective was to assess the relationship between high blood glucose levels (BG) in the early postoperative period and the incidence of surgical site infections (SSIs), sepsis, and death following colorectal operations. METHODS: The Michigan Surgical Quality Collaborative database was queried for colorectal operations from July 2012 to December 2013. Normoglycemic (BG < 180 mg/dL) and hyperglycemic (BG ≥ 180 mg/dL) groups were defined by using the highest BG within the first 72 h postoperatively. Outcomes of interest included the incidence of superficial, deep, and organ/space SSIs, sepsis, and death within 30 days. Initial unadjusted analysis was followed by propensity score matching and multiple logistic regression modeling after adjusting for significant predictors. Separate analyses were performed for previously diagnosed diabetic and non-diabetic patients. RESULTS: A total of 5145 cases met inclusion criteria, of which 1072 were diabetic. For diabetic patients, there was a marginally significant association between high BG and superficial SSI in the unadjusted analysis (OR = 1.75, p = 0.056), but not in the adjusted analysis (OR = 1.35, p = 0.39). There was no significant relationship between elevated BG and deep SSI, organ/space SSI, sepsis, or death among diabetic patients. For non-diabetic patients, there was a significant association between high BG and superficial SSI (OR = 1.53, p = 0.03), sepsis (OR = 1.61, p < 0.01), and death (OR = 2.26, p < 0.01), but not deep or organ/space SSI. CONCLUSIONS: Following colorectal operations, superficial SSI, sepsis, and death are associated with postoperative serum hyperglycemia in patients without diabetes, but not those with diabetes. Vigilant postoperative BG monitoring is critical for all patients undergoing colorectal surgery.

OBJECTIVE Clostridium difficile infection (CDI) is a common hospital-acquired infection. Previous reports on the incidence, risk factors, and impact of CDI on resources in the surgical population are limited. In this context, we study CDI across diverse surgical settings. METHODS We prospectively identified patients with laboratory-confirmed postoperative CDI after 40 different general, vascular, or gynecologic surgeries at 52 academic and community hospitals between July 2012 and September 2013. We used multivariable regression models to identify CDI risk factors and to determine the impact of CDI on resource utilization. RESULTS Of 35,363 patients, 179 (0.51%) developed postoperative CDI. The highest rates of CDI occurred after lower-extremity amputation (2.6%), followed by bowel resection or repair (0.9%) and gastric or esophageal operations (0.7%). Gynecologic and endocrine operations had the lowest rates (0.1% and 0%, respectively). By multivariable analyses, older age, chronic immunosuppression, hypoalbuminemia (≤3.5 g/dL), and preoperative sepsis were associated with CDI. Use of prophylactic antibiotics was not independently associated with CDI, neither was sex, body mass index (BMI), surgical priority, weight loss, or comorbid conditions. Three procedure groups had higher odds of postoperative CDI: lower-extremity amputations (adjusted odds ratio [aOR], 3.5; P=.03), gastric or esophageal operations (aOR, 2.1; P=.04), and bowel resection or repair (aOR, 2; P=.04). Postoperative CDI was independently associated with increased length of stay (mean, 13.7 d vs 4.5 d), emergency department presentations (18.9 vs 9.1%) and readmissions (38.9% vs 7.2%, all P<.001). CONCLUSIONS Incidence of postoperative CDI varies by surgical procedure. Postoperative CDI is also associated with higher rates of extended length of stay, emergency room presentations, and readmissions, which places a potentially preventable burden on hospital resources.

BACKGROUND: The practice of ambulatory surgery has expanded greatly as a result of advances in surgical technology and rising financial pressures. We sought to characterize the utilization of ambulatory surgical practices for common general surgical procedures in Michigan. MATERIALS AND METHODS: We identified 33,655 patients within the Michigan Surgery Quality Collaborative clinical registry undergoing general surgical procedures performed on an ambulatory basis between 25% and 75% of the time. Our primary outcome was the incidence of ambulatory surgery. Using multilevel mixed-effects logistic regression models, we adjusted ambulatory surgery utilization rates for patient comorbidities, procedure composition, and hospital characteristics. We then assessed the incidence of postoperative complications across hospitals grouped by their ambulatory surgery utilization rates. RESULTS: Adjusted utilization rates of ambulatory surgery varied widely across 34 hospitals from 29%-75% (mean = 54%). Risk-adjusted complication rates for ambulatory cases were similar between hospitals performing the least (2.2%) and the most ambulatory surgery (2.3%, P = 0.365). Patient factors and hospital characteristics accounted for 23.3% of the between-hospital variability in ambulatory surgery utilization, whereas most variation was explained by effects at the surgeon level. CONCLUSIONS: Despite wide variation in ambulatory surgery utilization for general surgical procedures, we were unable to explain observed differences by patient comorbidities, case mix, or hospital characteristics. These data suggest that understanding factors associated with ambulatory surgery utilization may represent a novel avenue for quality improvement within our statewide surgical collaborative.
