Community level socioeconomic status association with surgical outcomes and resource utilisation in a regional cohort: a prospective registry analysis.

BACKGROUND: Socioeconomic status affects surgical outcomes, however these factors are not included in clinical quality improvement data and risk models. We performed a prospective registry analysis to determine if the Distressed Communities Index (DCI), a composite socioeconomic ranking by zip code, could predict risk-adjusted surgical outcomes and resource utilisation. METHODS: All patients undergoing surgery (n=44,451) in a regional quality improvement database (American College of Surgeons-National Surgical Quality Improvement Program ACS-NSQIP) were paired with DCI, ranging from 0-100 (low to high distress) and accounting for unemployment, education level, poverty rate, median income, business growth and housing vacancies. The top quartile of distress was compared to the remainder of the cohort and a mixed effects modeling evaluated ACS-NSQIP risk-adjusted association between DCI and the primary outcomes of surgical complications and resource utilisation. RESULTS: A total of 9369 (21.1%) patients came from severely distressed communities (DCI >75), who had higher rates of most medical comorbidities as well as transfer status (8.4% vs 4.8%, p<0.0001) resulting in higher ACS-NSQIP predicted risk of any complication (8.0% vs 7.1%, p<0.0001). Patients from severely distressed communities had increased 30-day mortality (1.8% vs 1.4%, p=0.01), postoperative complications (9.8% vs 8.5%, p<0.0001), hospital readmission (7.7 vs 6.8, p<0.0001) and resource utilisation. DCI was independently associated with postoperative complications (OR 1.07, 95% CI 1.04 to 1.10, p<0.0001) as well as resource utilisation after adjusting for ACS-NSQIP predicted risk CONCLUSION: Increasing Distressed Communities Index is associated with increased postoperative complications and resource utilisation even after ACS-NSQIP risk adjustment. These findings demonstrate a disparity in surgical outcomes based on community level socioeconomic factors, highlighting the continued need for public health innovation and policy initiatives.

Multicenter Observational Study Examining the Implementation of Enhanced Recovery Within the Virginia Surgical Quality Collaborative in Patients Undergoing Elective Colectomy.

BACKGROUND: The American College of Surgeons (ACS) NSQIP Virginia Surgical Quality Collaborative (VSQC) exists to improve surgical outcomes through multi-institutional collaboration. Enhanced recovery (ER) protocols improve morbidity and reduce length of stay (LOS) after elective surgery. We hypothesized implementation of ER through VSQC would reduce postoperative complications and LOS in patients undergoing elective colectomy. Our objective was to evaluate whether standardization of care based on evidenced-based practices in healthcare settings across multiple institutions improved outcomes. STUDY DESIGN: In 2013, VSQC incrementally implemented ER for patients undergoing elective colectomy at participating institutions. Institutions shared protocols, order sets, educational materials, and met semi-annually to discuss progress. Risk-adjusted ACS NSQIP data (January 1, 2012 through December 31, 2016) was queried in 4 participating hospitals. The association of ER with surgical outcomes was evaluated with a before and after ER implementation analysis and multivariable logistic regression modeling with a priori selection of clinically relevant variables. RESULTS: There were 2,438 consecutive colectomies included in analysis (1,035 pre-ER/1,403 post-ER). In the post-ER implementation patient cohort, relatively more patients were treated laparoscopically (68%) compared with the pre-ER cohort (52%) (p < 0.001). Median LOS decreased from 5 to 4 days after ER implementation in patients undergoing open colectomy (p < 0.001), although total complications were similar in frequency (23% vs 22%). Laparoscopic patients had a reduced LOS (4 vs 3 days; p < 0.001), 30-day readmissions (12% vs 8%; p = 0.01), and total complications (16% vs 9%; p < 0.001) after ER implementation. In multivariable models, American Society of Anesthesiologists Physical Status Classification, hypertension, smoking, ER, and laparoscopy were independently associated with complication risk. CONCLUSIONS: Implementation of ER across VSQC was associated with reduction in LOS and complications in patients undergoing elective laparoscopic colectomy.

Opioid prescribing practices during implementation of an enhanced recovery program at a tertiary care hospital.

BACKGROUND: Enhanced recovery programs have demonstrated a decrease in opioid use in hospitals where patients have undergone colorectal surgery. This study is to investigate whether similar decreases in opioid prescribing are achieved at discharge and postdischarge. METHODS: Patients undergoing colorectal surgery November 2014-November 2016 were reviewed. Postdischarge opioid prescribing was quantified in morphine milligram equivalents at time of discharge, 30 days postdischarge, and 60 days postdischarge. Linear regression models were used to examine factors predictive of opioid prescribing. RESULTS: A total of 324 patients treated on enhanced recovery program protocol and 451 patients off enhanced recovery program protocol were reviewed. Enhanced recovery program patients had shorter lengths of stay: 6.74 ± 5.3 vs 9.0 ± 7.0 days (mean ± standard deviation; P < .0001). At discharge, enhanced recovery program patients were prescribed higher amounts of opioids (morphine milligram equivalent 307.4 ± 286.3 vs 242.5 ± 243.1 [mean ± SD]; P = .001) and were more likely to receive additional opioid prescriptions in the next 30 days (28.7% vs 18.85%; P = .0013). Linear regression models suggest that preoperative opioid use, age, and treatment on enhanced recovery program protocol were predictive of opioid prescribing (morphine milligram equivalent) at time of discharge. CONCLUSION: Enhanced recovery program patients received more opioid prescribing (morphine milligram equivalent) at discharge and within the first 30 days postdischarge. Alternative confounding variables require further investigation.

Narcotic-Dependent Patients Derive Equal Benefit from Enhanced Recovery.

Areas of the southeast United States have endemic levels of prescription drug use, diversion, and abuse. Because preoperative narcotics use is associated with increased surgical morbidity and increased readmission rates, there is a compelling need to categorize health outcomes of patients maintaining an active opioid prescription. The purpose of this study is to determine the health outcomes of preoperative narcotic users who undergo colorectal surgery within the enhanced recovery (ER) protocol, a set of multimodal interventions designed to reduce postoperative complications. Five hundred and five colorectal surgery patients were identified within the ER protocol at Carilion Clinic. Opioid dependence was defined as an active prescription for 30 days before surgery. Thirty-day outcome variables were defined by the National Surgical Quality Improvement Program. One hundred and one patients were identified as opioid dependent and 404 as opioid naïve. Groups were comparable in terms of age at surgery, mean body mass index, and presurgical physical classification. Groups fared similarly with regard to readmission (χ2, P > 0.999), reoperation (χ2, P = 0.869), and average length of stay [t(135) = 1.49, P = 0.137]. These preliminary data show that opioid-dependent patients derive benefit equal to opioid-naïve patients within the ER protocol.

An Expanded Preoperative Component within an Enhanced Recovery Protocol Improves Outcomes in Colorectal Surgery.

Enhanced Recovery Protocols (ERPs) have been shown to lead to quicker recovery in colorectal surgery, with reduced postoperative length of stay (LOS). ERPs could potentially be improved with an expanded preoperative component reflecting current evidence. We hypothesize that an ERP with an expanded preoperative component will reduce LOS consistent with or exceeding that seen with traditional ERPs. Our ERP was implemented in June of 2014. Data was collected for two full years from July 2014 through June 2016. The protocol was employed in colorectal cases, both elective and emergent. Data from ERP cases were compared with contemporaneous controls that did not go through the ERP. Patients who underwent colorectal procedures and participated in the ERP with the expanded preoperative component had an average LOS of 5.33 days, whereas controls stayed for an average of 7.93 days (P value, <0.01). ERP cases also experienced fewer readmissions and complications, although statistical significance could not be established. The results demonstrate that an ERP with an enhanced preoperative component significantly reduces LOS and potentially decreases the rate of readmissions and total complications.

Contact Isolation Precautions in Trauma Patients: An Analysis of Infectious Complications.

BACKGROUND: Victims of traumatic injuries represent a population at risk for a wide variety of complications. Contact isolation (CI) is a set of restrictions designed to help prevent the transmission of medically significant organisms in the healthcare setting. A growing body of literature demonstrates that CI can have significant implications for the individual isolated patient. Our goal was to characterize the use of contact isolation at our Level I trauma center and investigate the association of CI with infectious complications. PATIENTS AND METHODS: An existing trauma database containing data on patients admitted at our Level I trauma center between January 1, 2011 and December 31, 2012, along with their contact isolation status, was queried. Demographics, injuries, and the presence of infections were collected. Diagnosis of pneumonia or UTI was based on clinical documentation in the patient's medical record. A chart review was performed to ascertain the reason for CI including specific organisms. Because of differences in patient demographics between the CI and non-CI groups, linear regression was performed to adjust for the effects of different variables. RESULTS: A total of 4,423 patients were admitted over this period. Of these, 4,318 (97.6%) had complete records and were included in the subsequent analysis. The CI was in place in 249 (5.8%) patients; 4,069 (94.2%) were not isolated. The number who had CI initiated for MRSA nasal colonization was 173 (69.5%). Twenty-two (8.9%) had no reason for CI documented. Pneumonia occurred in 190 (4.4%), 54 (21.7) in the CI group versus 136 (3.3%) in the non-CI group. Urinary tract infection (UTI) was diagnosed in 166 (3.8%), 48 (19.3%) in the CI group versus 118 (2.9%) in the non-CI group. Using logistic regression and excluding patients placed on contact isolation for the development of a new resistant nosocomial infection, CI, Injury Severity Score, gender, length of stay, and mechanical ventilation were identified as common covariates for pneumonia (PNA) and UTI. Chronic obstructive pulmonary disease COPD was specifically identified for PNA. Spinal cord injury, vertebral column injury and pelvic-urogenital injury were also significant for UTI. CONCLUSIONS: The development of pneumonia and UTI in patients with trauma was significantly associated with the use of CI. Because the majority of these patients had CI precautions in place for asymptomatic colonization, the CI provided them no direct benefit. Because the use of CI is associated with multiple negative outcomes, its use in the trauma population needs to be carefully re-evaluated.

Perioperative Statin Treatment: Can It Decrease Postsurgical Cardiac Event Risk in Noncardiac Surgery?

Cardiac events are an important cause of postsurgical morbidity and mortality. Statin drugs have been studied as potentially risk-modifying agents in perioperative medicine. They have been shown to confer a protective benefit in cardiac surgery, but the evidence available in noncardiac surgery patient populations remains less conclusive. We hypothesized that perioperative statin treatment would be associated with lower incidence of postsurgical cardiac events (PSCEs) after major noncardiac surgery. A retrospective cohort study included 21,637 major noncardiac surgeries. Statin treatment was the exposure of interest and PSCE was the primary outcome measure. Data collection included patient age, body mass index, smoking status, diabetic status, cardiac event history, statin treatment history, and PSCE diagnoses. Perioperative statin treatment occurred in 4176 cases (19.3%). PSCEs occurred in 50 cases (0.23%), 29 in the untreated control group (0.17%) and 21 in the statin treatment group (0.50%). Relative risk in the untreated group was 0.3303 (95% confidence interval = 0.1886, 0.5786). This implied that statin-treated patients had higher risk than the untreated group. However, a logistic regression model that accounted for observed cardiac disease risk factors showed statin treatment not to be a significant predictor of PSCE in this sample. Analysis repeated in high-risk subsets of the cohort yielded similar results. A propensity score matching method that minimized differences between study groups also failed to demonstrate a significant association between statin treatment and PSCE risk. Our study did not demonstrate a significant association between perioperative statin treatment and PSCEs after major noncardiac surgery.

Potential return on investment for implementation of perioperative goal-directed fluid therapy in major surgery: a nationwide database study.

BACKGROUND: Preventable postsurgical complications are increasingly recognized as a major clinical and economic burden. A recent meta-analysis showed a 17-29 % decrease in postoperative morbidity with goal-directed fluid therapy. Our objective was to estimate the potential economic impact of perioperative goal-directed fluid therapy. METHODS: We studied 204,680 adult patients from 541 US hospitals who had a major non-cardiac surgical procedure between January 2011 and June 2013. Hospital costs (including 30-day readmission costs) in patients with and without complications were extracted from the Premier Inc. research database, and potential cost-savings associated with a 17-29 % decrease in postoperative morbidity were estimated. RESULTS: A total of 76,807 patients developed one or more postsurgical complications (morbidity rate 37.5 %). In patients with and without complications, hospital costs were US$27,607 ± 32,788 and US$15,783 ± 12,282 (p < 0.0001), respectively. Morbidity rate was anticipated to decrease to 26.6-31.1 % with goal-directed fluid therapy, yielding potential gross cost-savings of US$153-263 million for the study period, US$61-105 million per year, or US$754-1286 per patient. Potential savings per patient were highly variable from one surgical procedure to the other, ranging from US$354-604 for femur and hip-fracture repair to US$3515-5996 for esophagectomies. When taking into account the volume of procedures, the total potential savings per year were the most significant (US$32-55 million) for colectomies. CONCLUSIONS: Postsurgical complications occurred in more than one third of our study population and had a dramatic impact on hospital costs. With goal-directed fluid therapy, potential cost-savings per patient were US$754-1286. The highest cost-savings per year were observed for colectomies. These projections should help hospitals estimate the return on investment when considering the implementation of goal-directed fluid therapy.

Contact isolation is a risk factor for venous thromboembolism in trauma patients.

BACKGROUND: Contact isolation (CI) is a series of precautions used to prevent the transmission of medically significant infectious pathogens in the health care setting. Our institution's implementation of CI includes limiting patient movement to the assigned room. Our objective was to define the association between CI and venous thromboembolism (VTE) at our Level I trauma center. METHODS: Our institution's prospective trauma database was retrospectively queried for all patients admitted to the trauma service between January 1, 2011, and December 31, 2012. Data including demographics, Injury Severity Score (ISS), preexisting medical conditions, injury type, and VTE development were collected. CI status data were obtained from our institution's infection control database. χ2 was used to examine the unadjusted relationship between CI status and VTE. As the groups were not equivalent, logistic regression was then used to examine the relationship between CI and VTE while adjusting for relevant covariates including sex, age, ISS, and comorbidities. RESULTS: Of the 4,423 trauma patients admitted during the study period, 4,318 (97.6%) had complete records and were included in subsequent analyses. A total of 249 (5.8%) of the patients were on CI. VTE occurred in 44 patients (17.7%) on CI versus 141 patients (3.5%) who were not isolated (p < 0.0001; odds ratio, 6.0; 95% confidence interval, 4.1-8.6). With the use of lasso [least absolute shrinkage and selection operator] regression to adjust for patient risk factors, this relationship remained highly significant (p < 0.0001; odds ratio, 2.61; 95% confidence interval, 1.7-4.0). CONCLUSION: CI, ISS, hospital length of stay, and cardiac comorbidity were associated with VTE. After adjustment for other risk factors, CI remained most strongly associated with VTE. Although any medical intervention may come with unintended consequences, the risks and benefits of CI in this population need to be reevaluated. Further study is planned to identify opportunities to mitigate this increased VTE risk. LEVEL OF EVIDENCE: Prognostic/epidemiologic study, level III; therapeutic study, level IV.

Use of the national surgical quality improvement program to reduce surgical mortality: implementation of intensive preoperative screening and intervention.

The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) data at our institution indicated that surgical mortality was significantly higher than expected. This study examines the effect of implementation of a strict, intensive preoperative screening and intervention process on postoperative mortality at our institution, as measured by the NSQIP. Carilion Roanoke Memorial Hospital (CRMH) is a 763-bed tertiary care hospital serving a population of one million people in southwest Virginia. Data were collected for NSQIP at CRMH from July 2007 to December 2012. In January 2010, a new preoperative process was implemented to include risk assessment and intervention for hypertension, cardiac disease, pulmonary disease, diabetes, renal disease, and obstructive sleep apnea. Before initiation of our preoperative program (July 2007 to January 2010), odds ratios (ORs) for 30-day mortality in general and vascular cases were significantly higher than expected (1.40, 1.43, 1.58, and 1.56 in successive reporting periods). Beginning with the first report after implementation of the preoperative screening program, CRMH showed a progressively decreasing OR for overall 30-day mortality (1.26, 1.19, 1.14, 0.86, 0.82, 0.84, 0.89) with similar reductions in both general (0.92) and vascular (0.92) surgery. The implementation of an intensive preoperative screening and intervention process in our institution was accompanied by a significant decrease in the 30-day mortality for general surgery and vascular procedures, as measured by the NSQIP.

Higher surgical critical care staffing levels are associated with improved National Surgical Quality Improvement Program quality measures.

BACKGROUND: The changing face of American health care demands careful scrutiny of resource allocation. The impact of the surgical intensivist model on general surgical quality measures has not been studied. Our objective was to investigate the relationship between surgical critical care staffing and indicators of general surgical quality measured by the National Surgical Quality Improvement Program (NSQIP). METHODS: We retrospectively examined the number of attending surgical intensivists at our tertiary care center biannually from January 2008 through June 2012. Risk-adjusted indicators of general surgical quality were captured and reported semiannually by NSQIP. Mortality, overall morbidity, patients on ventilator for more than 48 hours, unplanned intubations, and venous thromboembolism were included. Student's t test was used to compare the staffing levels and associated NSQIP odds ratios of a 3-year control period of full commitment with a 2-year period following significant provider attrition. RESULTS: The number of full-time surgical intensivists ranged from 2 to 8, with a period of rapid decline in late 2010 to early 2011 followed by slow recovery. There was a mean of 6.6 surgical intensivists during the 3 years before the decline and a mean of 4 in the 2 years after the decline and recovery (p < 0.005). This period of decline was associated with a significant increase in the odds ratio of ventilation for more than 48 hours (before, 0.936; after, 1.87; p = 0.0086) and of venous thromboembolism (before, 0.844; after 1.43; p = 0.0268). A trend in increased unplanned intubations was also observed. Overall morbidity and mortality were not affected. Notably, quality indicators seemed to rapidly approach baseline levels as new surgical intensivists were recruited. CONCLUSION: Institutional commitment to recruitment and retention of a surgical critical care team leads to improved NSQIP general surgery quality measures. LEVEL OF EVIDENCE: Care management study, level IV.

Surgery for Crohn's disease and anti-TNF agents: the changing scenario.

Surgery has been a mainstay of therapy for Crohn's disease for a long time, essentially as a consequence of the fairly modest efficacy of traditional medications such as immunomodulators, antibiotics and 5-ASA, especially in severe cases. However, in the past decade and half, the advent of anti-TNF agents has greatly changed the medical approach to this disease and may modify its general management as well. Here, we have reviewed the current literature on incidence of surgery, timing of surgery and postoperative recurrence of Crohn's disease before and after the advent of anti-TNF agents. In addition, we have reviewed the risk of perioperative complications in patients on anti-TNF agents before surgery. The data show that the use of these medications is changing or expecting to change shortly a number of surgical aspects of Crohn's disease management.

Surgical failures: is it the surgeon or the patient? The all too often missed diagnosis of Ehlers-Danlos syndrome.

Ehlers-Danlos syndrome (EDS) is a closely related group of disorders caused by a heritable defect in collagen synthesis, which leads to marked healing difficulties. It has been estimated to occur in between one in 2500 and one in 5000 individuals but likely occurs more frequently than reported. EDS has probably been seen by all general surgeons several times over the course of a career. The purpose of this report is to describe the findings that should raise the index of suspicion, to aid in the diagnosis, and to characterize the general surgical procedures seen in patients with EDS by reviewing a single surgeon's experience in managing such patients with a review of the literature. Recommendations for treatment are given. A retrospective review of the experience of a single surgeon of 25 procedures in 15 patients with EDS is being reported. This is believed to be the largest series by one surgeon as yet reported. There was a wide variety of procedures performed, including ventral hernia repair (n = 6), inguinal hernia repair (n = 4), colectomy (n = 3), anal fistula (n = 3), and one each of an exploratory laparotomy, an appendectomy, a closure of a dehiscence, a Hickman catheter placement, an open lysis of adhesions for small bowel obstruction (SBO), a laparoscopic lysis of adhesions for SBO, an open cholecystectomy, a laparoscopic cholecystectomy, and an excision of a round ligament endometrioma. There was only one death, which was in a patient with Type IV EDS who was the first patient in this series. He presented with a spontaneous sigmoid perforation treated by Hartmann procedure and went on to develop two more colon perforations and to die of sepsis. The morbidity included only two recurrent ventral hernias, a wound dehiscence, a wound hematoma, and recurrence of the anal fistula. Although patients with EDS pose significant healing problems, successful general surgical procedures can be performed in most patients. Among other recommendations, total avoidance of colon anastomoses and colostomies in favor of total abdominal colectomy and ileostomy and routine closure of the abdominal wall with mesh or retention sutures is advocated. Making the diagnosis is the key to having successful outcomes. Further recommendations on avoiding operation and on the conduct of the operation, if needed, are given.

Effects of computerized decision support systems on blood glucose regulation in critically ill surgical patients.

BACKGROUND: The use of computerized decision support systems (CDSS) in glucose control for critically ill surgical patients has been reported in both diabetic and nondiabetic patients. Prospective studies evaluating its effect on glucose control are, however, lacking. The objective of this study was to evaluate patient-specific computerized IV insulin dosing on blood glucose levels (BGLs) by comparing patients treated pre-CDSS with those treated post-CDSS. STUDY DESIGN: A prospective study was performed in 4 surgical ICUs and 1 progressive care unit comparing patient data pre- and post-implementation of CDSS. The primary outcomes measures were the impact of the CDSS on glycemic control in this population and on reducing the incidence of severe hypoglycemia. RESULTS: Data on 1,682 patient admissions were evaluated, which corresponded to 73,290 BGLs post-CDSS compared with 44,972 BGLs pre-CDSS. The percentage of hyperglycemic events improved, with BGLs of >150 mg/dL decreasing by 50% compared with 6-month historical controls during the 18-month study period from July 2010 through December 2011. This was true for all 5 units individually (p < 0.0001, by one sample sign test). In addition, severe hypoglycemia (defined as BGL <40 mg/dL) decreased from 1% to 0.05% after implementing CDSS (p < 0.0001 by 2-sided binomial test). CONCLUSIONS: Patients whose BGLs were managed using CDSS were statistically significantly more likely to have a glucose reading under control (<150 mg/dL) than in the 6-month historical controls and to avoid serious hypoglycemia (p < 0.0001).
