BACKGROUND: Patients with IBD have a higher baseline risk of venous thromboembolism, which further increases with surgery. Therefore, extended venous thromboembolism chemoprophylaxis has been suggested in certain high-risk cohorts. OBJECTIVE: The purpose of this study was to determine whether the underlying diagnosis, operative procedure, or both influence the incidence of postoperative venous thromboembolism. DESIGN: This was a retrospective review. SETTINGS: The American College of Surgeons–National Surgical Quality Improvement Project database was analyzed. PATIENTS: The NSQIP database was queried for patients with chronic ulcerative colitis and non-IBD undergoing colorectal resections using surgical Current Procedural Terminology codes modeled after the 3 stages used for the surgical management of chronic ulcerative colitis from 2005 to 2013. MAIN OUTCOME MEASURES: We measured 30-day postoperative venous thromboembolism risk in patients with chronic ulcerative colitis based on operative stage and risk factors for development of venous thromboembolism. RESULTS: A total of 18,833 patients met inclusion criteria, with an overall rate of venous thromboembolism of 3.8. Among procedure risk groups, venous thromboembolism rates were high risk, 4.4%; intermediate risk, 1.6%; and low risk, 0.7% (across risk groups, p < 0.01). Emergent case subjects exhibited a higher rate of venous thromboembolism than their elective counterparts (6.9% vs 3.1%). Factors significantly associated with venous thromboembolism on adjusted analysis included emergent risk case (adjusted OR = 7.85), high-risk elective case (adjusted OR = 5.07), intermediate-risk elective case (adjusted OR = 2.69), steroid use (adjusted OR = 1.54), and preoperative albumin <3.5 g/dL (adjusted OR = 1.45). LIMITATIONS: Because of its retrospective nature, correlation between procedures and venous thromboembolism risk can be demonstrated, but causation cannot be proven. In addition, data on inpatient and extended venous thromboembolism prophylaxis use are not available. CONCLUSIONS: Emergent status and operative procedure are the 2 highest risk factors for postoperative venous thromboembolism. Extended venous thromboembolism prophylaxis might be appropriate for patients undergoing these high-risk procedures or any emergent colorectal procedures.

Objectives We aimed to determine the rates of readmission and reoperation for patients undergoing surgery for pelvic organ prolapse (POP). Methods The American College of Surgeons National Surgical Quality Improvement Program Participant User File was used to select all surgeries performed for POP from 2012 through 2014. The cohort was then reviewed for unplanned readmissions and unplanned reoperations within 30 days of POP surgery. Patient and procedural factors associated with readmission or reoperation were compared using χ2 analyses and Student t test. Multivariable logistic regression determined independent risk factors for both readmission and reoperation. Results A total of 23,419 patients underwent surgery for POP. Of these, there were 435 (1.9%) readmissions and 341 (1.5%) reoperations within 30 days. Median numbers of days from index procedure to readmission or reoperation were 9 and 8 days, respectively. Those who were readmitted had higher American Society of Anesthesia (ASA) scores, longer operative times, and longer lengths of stay than those who were not readmitted (all P < 0.001). Patients who underwent unplanned reoperation also had higher ASA scores, longer operative times, and longer lengths of stay than those who did not undergo reoperation (all P < 0.01). The most common reasons for readmission were surgical site infection (SSI) (19.3%) and non-SSI (15.9%). The most common reason for reoperation was urologic (27.6%) such as cystoscopy or stent placement. Conclusions Readmission and reoperation rates are relatively low for patients undergoing surgery for POP. Infection, both SSI and non-SSI, accounted for 35.2% of readmissions. Identification of ASA score of 3 or higher, longer total operating time, and increased length of stay is associated with unplanned readmission and reoperation.

Abstract Background: Surgical site infections (SSI) contribute to surgical patients' morbidity and costs. Operating room traffic may be a modifiable risk factor for SSI. We investigated the impact of additional operating room personnel on the risk of superficial SSI (sSSI). Patients and Methods: In this matched case-control study, cases included patients in whom sSSI developed in clean surgical incisions after elective, daytime operations. Control subjects were matched by age, gender, and procedure. Operating room personnel were classified as (1) surgical scrubbed, (2) surgical non-scrubbed, or (3) anesthesia. We used conditional logistic regression to test the extent to which additional personnel overall and from each work group were associated with infection. Results: In total, 474 patients and 803 control subjects were identified. Each additional person among total personnel and personnel from each work group was significantly associated with greater odds of infection (all personnel, odds ratio [OR] = 1.082, 95% confidence interval [CI] 1.031–1.134, p = 0.0013; surgical scrubbed OR = 1.132, 95% CI 1.029–1.245, p = 0.0105; surgical non-scrubbed OR = 1.123, 95% CI 1.008–1.251, p = 0.0357; anesthesia OR = 1.153, 95% CI 1.031–1.290, p = 0.0127). After adjusting for operative duration, body mass index, diabetes mellitus, and vascular disease, additional personnel and sSSI were no longer associated overall or for any work groups (total personnel OR = 1.033, 95% CI 0.974–1.095, p = 0.2746; surgical scrubbed OR = 1.060, 95% CI 0.952-1.179, p = 0.2893; surgical non-scrubbed OR = 1.023 95% CI 0.907–1.154, p = 0.7129; anesthesia OR = 1.051, 95% CI 0.926–1.193, p = 0.4442). Conclusion: The presence of additional operating room personnel was not independently associated with increased odds of sSSI. Efforts dedicated to sSSI reduction should focus on other modifiable risk factors.

AbstractIntroductionDespite advances in trauma care, hemorrhage continues to be the leading cause of preventable mortality in trauma. The evidence to support its use in non‐trauma patients is limited. We aim to report our experience with prehospital blood product transfusion. We hypothesize that it is safe, appropriately utilized, and that our protocol, which was designed for trauma patients, is adaptable to fit the needs of non‐trauma patients.MethodsPatients transfused with blood products, packed red blood cells (pRBCs) or plasma, in the prehospital environment between 2002 and 2014 were included. Trauma patients were compared to non‐trauma patients using descriptive statistics.ResultsA total of 857 patients (n = 549 trauma and n = 308 non‐trauma) were transfused with pRBCs (76 %, n = 654, mean 1.6 ± 1.1 units en route), plasma (53 %, n = 455, mean 1.7 ± 0.7 unit), or both (29 %, n = 252) during ground (12 %) or air (84 %) critical care transport. Mean age was 60.8 ± 21.6 years with 60.1 % (n = 515) males. Subsequently, in‐hospital blood transfusions were performed in 80 % of patients, operations in 44 %, and endoscopy in 31 %. Five percent (n = 41) of patients did not require any of these interventions. Thirty‐day mortality rate was 18 %, and one patient (<0.01 %) had a transfusion reaction. The majority of patients were non‐trauma (n = 549, 64 %). Of the non‐trauma patients, 219 (40 %) were surgical, 193 (35 %) gastrointestinal bleeds, and 137 (25 %) medical.ConclusionBoth non‐trauma and trauma patients require blood products for life threatening hemorrhage and the majority required further interventions. Further research on the benefits of transfusion among non‐trauma patients is warranted.

ObjectivesPerformance measurement is used by health care providers, payers, and patients. Historically accomplished using administrative data, registries are used increasingly to track and improve care. We assess how measured diabetes care quality differs when calculated using claims versus registry.Data Sources/Study SettingCross‐sectional analysis of administrative claims and electronic health records (EHRs) of patients in a multispecialty integrated health system in 2012 (n = 368,883).Study DesignWe calculated percent of patients attaining glycohemoglobin <8.0 percent, LDL cholesterol <100 mg/dL, blood pressure <140/90 mmHg, and nonsmoking (D4) in cohorts, identified by Medicare Accountable Care Organization/Minnesota Community Measures (ACO‐MNCM; claims‐based), Healthcare Effectiveness Data and Information Set (HEDIS; claims‐based), and registry (EHR‐based).Data Collection/Extraction MethodsClaims were linked to EHR to create a dataset of performance‐eligible patients.Principal FindingsACO‐MNCM, HEDIS, and registry identified 6,475, 6,989, and 6,425 measurement‐eligible patients. Half were common among the methods; discrepancies were due to attribution, age restriction, and encounter requirements. D4 attainment was lower in ACO‐MNCM (36.09 percent) and HEDIS (37.51 percent) compared to registry (43.74 percent) cohorts.ConclusionsRegistry‐ and claims‐based performance measurement methods identify different patients, resulting in different rates of quality metric attainment with implications for innovative population health management.
