Outcomes of laparoscopic and open ventriculoperitoneal shunt placement.

OBJECTIVE: Ventriculoperitoneal (VP) shunt placement requires a concurrent abdominal procedure. For peritoneal access laparoscopic or open approach may be utilized. Our aim was to compare patient/procedure characteristics and outcomes by peritoneal approach for VP shunts in children. METHODS: NSQIP-Pediatric procedure targeted cerebral spinal fluid shunt Participant Use Data Files from 2016 to 2020 were queried. Patients were grouped into laparoscopic vs open abdominal approach. Patient demographics, procedure characteristics and 30-day outcomes were compared. RESULTS: 7742 NSQIP-Pediatric patients underwent VP shunt placement. Patients undergoing laparoscopic approach were older and required less preoperative support. Mean operative time was longer with laparoscopy (mean(SD): 74.2(48.1) vs. 64.6(39) minutes, p â€‹< â€‹0.0001) but had shorter hospital LOS. There was no difference in SSI, readmissions, or reoperation rates. CONCLUSION: Patients undergoing laparoscopy for distal VP shunts are older with less support needs preoperatively. While laparoscopic approach had a shorter hospital LOS, there was no demonstratable difference in SSI, readmissions or reoperations between approaches. Further studies are needed to assess long-term outcomes.

Preoperative intervention for smoking cessation: A systematic review.

BACKGROUND: Smoking is associated with increased postoperative complications. Pre-surgical smoking cessation remains a challenge. Our aim was to summarize pre-hospital smoking cessation interventions and impact on smoking cessation rates. METHODS: Independent review of English language articles identified from systematic searches of MEDLINE, PubMed, PsycInfo, Embase, Web of Science, and Cumulative Index to Nursing & Allied Health Literature databases from 1998 to 2019 was performed (PROSPERO registration number CRD42021247927). Studies of adult patients enrolled in a pre-hospital smoking cessation intervention were included. Studies with historical controls or only self-reported outcomes were excluded. RESULTS: Nine articles including 1762 patients were identified. Exhaled CO was used to confirm cessation. Six studies reported smoking status day of surgery. Interventions included NRT, hand-held technology, e-cigarettes, decision aids/counseling and medications. Four studies demonstrated a difference in smoking cessation rates. Ethics and study appraisal were assessed using ROB2. CONCLUSIONS: Based on the variability of interventions, settings, and outcomes, best practice for successful pre-hospital smoking cessation in surgery clinics would benefit from ongoing investigation.

Virtual triage from freestanding emergency departments: a propensity score-weighted analysis of short-term outcomes in emergency general surgery.

BACKGROUND: Freestanding emergency departments (FSEDs) have generated improved hospital metrics, including decreased ED wait times and increased patient selection. Patient outcomes and process safety have not been evaluated. This study investigates the safety of FSED virtual triage in the emergency general surgery (EGS) patient population. METHODS AND PROCEDURES: A retrospective review evaluated all adult EGS patients admitted to a community hospital between January 2016 and December 2021 who either presented at a FSED and received virtual evaluation from a surgical team (fEGS) or presented at the community hospital emergency department and received in-person evaluation from the same surgical group (cEGS). Patients' demographics, acute care utilization history, and clinical characteristics at the onset of the index visit were used to build a propensity score model and stabilized Inverse Probability of Treatment Weights (IPTW) were used to create a weighted sample. Multivariable regression models were then employed to the weighted sample to evaluate the treatment effect of virtual triage compared to in-person evaluation on short-term outcomes, including length of stay (LOS) and 30-day readmission and mortality. Variables which occurred during the index visit (such as surgery duration and type of surgery) were adjusted for in the multivariable analyses. RESULTS: Of 1962 patients, 631 (32.2%) were initially evaluated virtually (fEGS) and 1331 (67.8%) underwent an in-person evaluation (cEGS). Baseline characteristics demonstrated significant differences between the cohorts in gender, race, payer status, BMI, and CCI score. Baseline risks were well balanced in the IPTW-weighted sample (SD range 0.002-0.18). Multivariable analysis found no significant differences between the balanced cohorts in 30-day readmission, 30-day mortality, and LOS (p > 0.05 for all). CONCLUSION: Patients who undergo virtual triage have similar outcomes to those who undergo in-person triage for EGS diagnoses. Virtual triage at FSED for these EGS patients may be an efficient and safe means for initial evaluation.

Implementation of a Gastrografin Order Set for Small Bowel Obstruction Across a Health System: A Cohort Study.

BACKGROUND: The use of Gastrografin (GG) in the management of adhesive small bowel obstruction (SBO) has been shown to decrease the length of stay and operative intervention. METHODS: This retrospective cohort study examined patients with an SBO diagnosis prior to implementation (PRE, January 2017-January 2019) and following implementation (POST, January 2019-May 2021) of a GG challenge order set made available across 9 hospitals within a health care system. Primary outcomes were utilization of the order set across facilities and over time. Secondary outcomes included time to surgery for operative patients, rate of surgery, nonoperative length of stay, and 30-day readmission. Standard descriptive, univariate, and multivariable regression analyses were performed. RESULTS: PRE cohort had 1746 patients and POST had 1889. The utilization of GG increased from 14% to 49.5% following implementation. Significant variability existed within the hospital system with utilization at each individual hospital from 11.5% to 60%. There was an increase in surgical intervention (13.9% vs 16.4%, P = .04) and decrease in nonoperative LOS (65.6 vs 59.9 hours, P < .001) following implementation. For POST patients, multivariable linear regression showed significant reduction in nonoperative length of stay (-23.1 hours, P < .001) but no significant difference in time to surgery (-19.6 hours, P = .08). DISCUSSION: The availability of a standardized order set for SBO can result in increased Gastrografin administration across hospital settings. The implementation of a Gastrografin order set was associated with decreased length of stay in nonoperative patients.

Just What the Doctor Ordered: Missed Ordering of Venous Thromboembolism Chemoprophylaxis Is Associated With Increased VTE Events in High-risk General Surgery Patients.

OBJECTIVE: To define the impact of missed ordering of venous thromboembolism (VTE) chemoprophylaxis in high-risk general surgery populations. BACKGROUND: The primary cause of preventable death in surgical patients is VTE. Although guidelines and validated risk calculators assist in dosing recommendations, there remains considerable variability in ordering and adherence to recommended dosing. METHODS: All adult inpatients who underwent a general surgery procedure between 2016 and 2019 and were entered into Atrium Health National Surgical Quality Improvement Program registry were identified. Patients at high risk for VTE (2010 Caprini score ≥5) and without bleeding history and/or acute renal failure were included. Primary outcome was 30-day postoperative VTE. Electronic medical record identified compliance with "perfect" VTE chemoprophylaxis orders (pVTE): no missed orders and no inadequate dose ordering. Multivariable analysis examined association between pVTE and 30-day VTE events. RESULTS: A total of 19,578 patients were identified of which 4252 were high-risk inpatients. Hospital compliance of pVTE was present in 32.4%. pVTE was associated with shorter postoperative length of stay and lower perioperative red blood cell transfusions. There was 50% reduced odds of 30-day VTE event with pVTE (odds ratio: 0.50; 95% CI, 0.30-0.80) and 55% reduction in VTE event/mortality (odds ratio: 0.45; 95% CI, 0.31-0.63). After controlling for relevant covariates, pVTE remained significantly associated with decreased odds of VTE event and VTE event/mortality. CONCLUSIONS: pVTE ordering in high-risk general surgery patients was associated with 42% reduction in odds of postoperative 30-day VTE. Comprehending factors contributing to missed or suboptimal ordering and development of quality improvement strategies to reduce them are critical to improving outcomes.

Impact of COVID-19 on common non-elective general surgery diagnoses.

BACKGROUND: During the COVID-19 pandemic, public health and hospital policies were enacted to decrease virus transmission and increase hospital capacity. Our aim was to understand the association between COVID-19 positivity rates and patient presentation with EGS diagnoses during the COVID pandemic compared to historical controls. METHODS: In this cohort study, we identified patients ≥ 18 years who presented to an urgent care, freestanding ED, or acute care hospital in a regional health system with selected EGS diagnoses during the pandemic (March 17, 2020 to February 17, 2021) and compared them to a pre-pandemic cohort (March 17, 2019 to February 17, 2020). Outcomes of interest were number of EGS-related visits per month, length of stay (LOS), 30-day mortality and 30-day readmission. RESULTS: There were 7908 patients in the pre-pandemic and 6771 in the pandemic cohort. The most common diagnoses in both were diverticulitis (29.6%), small bowel obstruction (28.8%), and appendicitis (20.8%). The lowest relative volume of EGS patients was seen in the first two months of the pandemic period (29% and 40% decrease). A higher percentage of patients were managed at a freestanding ED (9.6% vs. 8.1%) and patients who were admitted were more likely to be managed at a smaller hospital during the pandemic. Rates of surgical intervention were not different. There was no difference in use of ICU, ventilator requirement, or LOS. Higher 30-day readmission and lower 30-day mortality were seen in the pandemic cohort. CONCLUSIONS: In the setting of the COVID pandemic, there was a decrease in visits with EGS diagnoses. The increase in visits managed at freestanding ED may reflect resources dedicated to supporting outpatient non-operative management and lack of bed availability during COVID surges. There was no evidence of a rebound in EGS case volume or substantial increase in severity of disease after a surge declined.

Emergency General Surgery Regionalization: Retrospective Cohort Study of Emergency General Surgery Patients at a Tertiary Care Center.

BACKGROUND: Emergency general surgery (EGS) patients presenting at tertiary care hospitals may bypass local hospitals with adequate resources. However, many tertiary care hospitals frequently operate at capacity. We hypothesized that understanding patient geographic origin could identify opportunities for enhanced system triage and optimization and be an important first step for EGS regionalization and care coordination that could potentially lead to improved utilization of resources. METHODS: We analyzed patient zip code and categorized EGS patients who were cared for at our tertiary care hospital as potentially divertible if the southern region hospital was geographically closer to their home, regional hospital admission (RHA) patients, or local admission (LA) patients if the tertiary care facility was closer. Baseline characteristics and outcomes were compared for RHA and LA patients. RESULTS: Of 14 714 EGS patients presenting to the tertiary care hospital, 30.2% were categorized as RHA patients. Overall, 1526 (10.4%) patients required an operation including 527 (34.5%) patients who were potentially divertible. Appendectomy and cholecystectomy comprised 66% of the operations for potentially divertible patients. Length of stay was not significantly different (P = .06) for RHA patients, but they did have lower measured short-term and long-term mortality when compared to their LA counterparts (P < .05). CONCLUSIONS: EGS diagnoses and patient geocode analysis can identify opportunities to optimize regional operating room and bed utilization. Understanding where EGS patients are cared for and factors that influenced care facility will be critical for next steps in developing EGS regionalization within our system.

Emergencies do not shut down during a pandemic: COVID pandemic impact on Acute Care Surgery volume and mortality at a level I trauma center.

BACKGROUND: The aim of this study was to evaluate the impact of the COVID-19 pandemic on volume and outcomes of Acute Care Surgery patients, and we hypothesized that inpatient mortality would increase due to COVID+ and resource constraints. METHODS: An American College of Surgeons verified Level I Trauma Center's trauma and operative emergency general surgery (EGS) registries were queried for all patients from Jan. 2019 to Dec. 2020. April 1st, 2020, was the demarcation date for pre- and during COVID pandemic. Primary outcome was inpatient mortality. RESULTS: There were 14,460 trauma and 3091 EGS patients, and month-over-month volumes of both remained similar (p > 0.05). Blunt trauma decreased by 7.4% and penetrating increased by 31%, with a concomitant 25% increase in initial operative management (p < 0.001). Despite this, trauma (3.7%) and EGS (2.9-3.0%) mortality rates remained stable which was confirmed on multivariate analysis; p > 0.05. COVID + mortality was 8.8% and 3.7% in trauma and EGS patients, respectively. CONCLUSION: Acute Care Surgeons provided high quality care to trauma and EGS patients during the pandemic without allowing excess mortality despite many hardships and resource constraints.

The physiology of failure: Identifying risk factors for mortality in emergency general surgery patients using a regional health system integrated electronic medical record.

BACKGROUND: Emergency general surgery (EGS) patients have increased mortality risk compared with elective counterparts. Recent studies on risk factors have largely used national data sets limited to administrative data. Our aim was to examine risk factors in an integrated regional health system EGS database, including clinical and administrative data, hypothesizing that this novel process would identify clinical variables as important risk factors for mortality. METHODS: Our nine-hospital health system's billing data were queried for EGS International Classification of Disease codes between 2013 and 2018. Codes were grouped by diagnosis, and urgent or emergent encounters were included and merged with electronic medical record clinical data. Outcomes assessed were inpatient and 1-year mortality. Standard and multivariable statistics evaluated factors associated with mortality. RESULTS: There were 253,331 EGS admissions with 3.6% inpatient mortality rate. Patients who suffered inpatient and 1-year mortality were older, more likely to be underweight, and have neutropenia or elevated lactate. On multivariable analysis for inpatient mortality: age (odds ratio [OR], 1.7-6.7), underweight body mass index (OR, 1.6), transfer admission (OR, 1.8), leukopenia (OR, 2.0), elevated lactate (OR, 1.8), and ventilator requirement (OR, 7.1) remained associated with increased risk. Adjusted analysis for 1-year mortality demonstrated similar findings, with highest risk associated with older age (OR, 2.8-14.6), underweight body mass index (OR, 2.3), neutropenia (OR, 2.0), and tachycardia (OR, 1.7). CONCLUSION: After controlling for patient and disease characteristics available in administrative databases, clinical variables remained significantly associated with mortality. This novel yet simple process allows for easy identification of clinical data points imperative to the study of EGS diagnoses that are critical in understanding factors that impact mortality. LEVEL OF EVIDENCE: Prognostic and Epidemiologic; Level III.

Emergency General Surgery Transfer and Effect on Inpatient Mortality and Post-Discharge Emergency Department Visits: A Propensity Score Matched Analysis.

BACKGROUND: Patients undergoing emergency general surgery (EGS) and interhospital transfer (IHT) have increased mortality. Prior analyses of IHT have been limited by the inability to track post-discharge outcomes or have not included nonoperative EGS. We evaluated outcomes for IHT to our tertiary care facility compared with direct admission through the emergency department. STUDY DESIGN: Patients admitted directly (2015 to 2017) with a common EGS diagnosis (appendicitis, cholecystitis, choledocholithiasis, small bowel obstruction, and diverticulitis) were propensity score matched to patients transferred from another acute care hospital. Propensity score matching (PSM) was performed using patient characteristics, EGS diagnosis, comorbidities, and surgical critical care consultation. The primary outcome was inpatient mortality, and secondary outcomes were length of stay (LOS) 30-day hospital readmission. RESULTS: We identified 3,153 directly admitted patients and 1,272 IHT patients. IHT patients were older (mean 59.4 vs 51.5 years), had a higher Charlson comorbidity index (median 3 vs 1), White race (72% vs 49%), and BMI greater than 40 kg/m2 (11.6% vs 9.8%). After PSM, each group included 1,033 patients. IHT patients had a higher median LOS (5.5 days vs 3.8, p < 0.001), higher inpatient mortality (odds ratio [OR] 1.69, p = 0.03), and more complications (OR 1.57, p < 0.001). The rate of post-discharge 30-day hospital encounters was similar (OR 1.08, p = 0.460). However, IHT patients had more emergency department encounters (OR 1.35, p = 0.04) and fewer observation-status readmissions (OR 0.53, p = 0.01). CONCLUSIONS: After PSM to reduce confounding variables, patients with common EGS diagnoses transferred to a tertiary care facility have increased inpatient morbidity and mortality. The increased morbidity and resource utilization for these patients extends beyond the index hospital stay.

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.

Deconstructing the roadmap to surgical residency: a national survey of residents illuminates factors associated with recruitment success as well as applicants' needs and beliefs.

Purpose: As applications increase and residency becomes more competitive, applicants and programs will be challenged by increased demands on recruitment, metric assessment, and rank determination. Studies have investigated program opinions; however, this survey sought to illuminate the process from an applicant's perspective. Methods: An anonymous survey was distributed to past or current surgery residents nationwide using social media and program director emails. Regression analyses were performed to assess factors correlating with percentage of programs which offered the applicant an interview. Results: There were 223 respondents who applied to an average of 61 programs (± 40) with 16 (± 11) interviews offered. Applicants believed that programs were most interested in (1) personality, (2) letter of recommendation (LOR) writers, and (3) medical school reputation. Top factors considered by applicants in ranking were resident culture, location, program reputation, and autonomy. Bivariate analysis found factors that decreased percent of interview invites to be Asian race, whereas factors that increased interview invites included age, year of match, surgery clerkship grade, medicine clerkship grade, AOA status, honor surgery rotation, gold humanism (GHHS) status, phone call for interview made, and step scores (all p < 0.05). AOA status, step scores, honor surgery rotation, year of match, and Asian race remained significant after multivariate analysis. Conclusions: National surveys illuminate how applicants approach the application process and what programs and applicants appear to value. This information provides insight and guidance to candidates and programs as the process of matching becomes more challenging with surging application numbers, changes in testing parameters and virtual interviews.

Emergency general surgery transfer to lower acuity facility: The role of right-sizing care in emergency general surgery regionalization.

BACKGROUND: Regionalization of emergency general surgery (EGS) has primarily focused on expediting care of high acuity patients through interfacility transfers. In contrast, triaging low-risk patients to a nondesignated trauma facility has not been evaluated. This study evaluates a 16-month experience of a five-surgeon team triaging EGS patients at a tertiary care, Level I trauma center (TC) to an affiliated community hospital 1.3 miles away. METHODS: All EGS patients who presented to the Level I TC emergency department from January 2020 to April 2021 were analyzed. Patients were screened by EGS surgeons covering both facilities for transfer appropriateness including hemodynamics, resource need, and comorbidities. Patients were retrospectively evaluated for disposition, diagnosis, comorbidities, length of stay, surgical intervention, and 30-day mortality and readmission. RESULTS: Of 987 patients reviewed, 31.5% were transferred to the affiliated community hospital, 16.1% were discharged home from the emergency department, and 52.4% were admitted to the Level I TC. Common diagnoses were biliary disease (16.8%), bowel obstruction (15.7%), and appendicitis (14.3%). Compared with Level I TC admissions, Charlson Comorbidity Index was lower (1.89 vs. 4.45, p < 0.001) and length of stay was shorter (2.23 days vs. 5.49 days, p < 0.001) for transfers. Transfers had a higher rate of surgery (67.5% vs. 50.1%, p < 0.001) and lower readmission and mortality (8.4% vs. 15.3%, p = 0.004; 0.6% vs. 5.0%, p < 0.001). Reasons not to transfer were emergency evaluation, comorbidity burden, operating room availability, and established care. No transfers required transfer back to higher care (under-triage). Bed days saved at the Level I TC were 693 (591 inpatients). Total operating room minutes saved were 24,008 (16,919, between 7:00 am and 5:00 pm). CONCLUSION: Transfer of appropriate patients maintains high quality care and outcomes, while improving operating room and bed capacity and resource utilization at a tertiary care, Level I TC. Emergency general surgery regionalization should consider triage of both high-risk and low-risk patients. LEVEL OF EVIDENCE: Prospective comparative cohort study, Level II.

Laparoscopy is associated with decreased all-cause mortality in patients undergoing emergency general surgery procedures in a regional health system.

BACKGROUND: The aim of this study was to evaluate the use of laparoscopic surgery for common emergency general surgery (EGS) procedures within an integrated Acute Care Surgery (ACS) network. We hypothesized that laparoscopy would be associated with improved outcomes. METHODS: Our integrated health care system's EGS registry created from AAST EGS ICD-9 codes was queried from January 2013 to October 2015. Procedures were grouped as laparoscopic or open. Standard descriptive and univariate tests were performed, and a multivariable logistic regression controlling for open status, age, BMI, Charlson Comorbidity Index (CCI), trauma tier, and resuscitation diagnosis was performed. Laparoscopic procedures converted to open were identified and analyzed using concurrent procedure billing codes across episodes of care. RESULTS: Of 60,604 EGS patients identified over the 33-month period, 7280 (12.0%) had an operation and 6914 (11.4%) included AAST-defined EGS procedures. There were 4813 (69.6%) surgeries performed laparoscopically. Patients undergoing a laparoscopic procedure tended to be younger (45.7 ± 18.0 years vs. 57.2 ± 17.6, p < 0.001) with similar BMI (29.7 ± 9.0 kg/m2 vs. 28.8 ± 8.3, p < 0.001). Patients in the laparoscopic group had lower mean CCI score (1.6 ± 2.3 vs. 3.4 ± 3.2, p ≤ 0.0001). On multivariable analysis, open surgery had the highest association with inpatient mortality (OR 8.67, 4.23-17.75, p < 0.0001) and at all time points (30-, 90-day, 1-, 3-year). At all time points, conversion to open was found to be a statistically significant protective factor. CONCLUSION: Use of laparoscopy in EGS is common and associated with a decreased risk of all-cause mortality at all time points compared to open procedures. Conversion to open was protective at all time points compared to open procedures.

The Obesity Paradox in Emergency General Surgery Patients.

BACKGROUND: Operative management of emergency general surgery (EGS) diagnoses involves a range of procedures which can carry high morbidity and mortality. Little is known about the impact of obesity on patient outcomes. The aim of this study was to examine the association between body mass index (BMI) >30 kg/m2 and mortality for EGS patients. We hypothesized that obese patients would have increased mortality rates. METHODS: A regional integrated health system EGS registry derived from The American Association for the Surgery of Trauma EGS ICD-9 codes was analyzed from January 2013 to October 2015. Patients were stratified into BMI categories based on WHO classifications. The primary outcome was 30-day mortality. Longer-term mortality with linkage to the Social Security Death Index was also examined. Univariate and multivariable analyses were performed. RESULTS: A total of 60 604 encounters were identified and 7183 (11.9%) underwent operative intervention. Patient characteristics include 53% women, mean age 58.2 ± 18.7 years, 64.2% >BMI 30 kg/m2, 30.2% with chronic obstructive pulmonary disease, 19% with congestive heart failure, and 31.1% with diabetes. The most common procedure was laparoscopic cholecystectomy (36.4%). Overall, 90-day mortality was 10.9%. In multivariable analysis, all classes of obesity were protective against mortality compared to normal BMI. Underweight patients had increased risk of inpatient (OR = 1.9, CI = 1.7-2.3), 30-day (OR = 1.9, CI = 1.7-2.1), 90-day (OR = 1.8, CI 1.6-2.0), 1-year (OR = 1.8, CI = 1.7-2.0), and 3-year mortality (OR = 1.7, CI = 1.6-1.9). CONCLUSIONS: When stratified by BMI, underweight EGS patients have the highest odds of death. Paradoxically, obesity appears protective against death, even when controlling for potentially confounding factors. Increased rates of nonoperative management in the obese population may impact these findings.
