Costs in Colectomy Episodes of Care: Opportunities to Prevent Emergency Operations and Decrease Costs.

INTRODUCTION: Payment structured around Episodes of Care is a method for incentivizing decreased care utilization after major procedures. We examined Major Bowel Episodes of Care (MB-EoC)-the focus among general surgery procedures-within a large health system to determine the contribution of emergency bowel surgery to higher costs of care. METHODS: Adult MB-EoC cases from July 2018 to June 2021 were reviewed for 90-d costs, examining patient age, insurance, diagnosis, cost of care, and contributors to cost. For patients aged ≥45 y who had nonelective care for colon cancer, incidence of prior screening colonoscopy was examined. RESULTS: We identified 1292 colectomy cases. Mean age was 65 y. Of these patients, 90% had Medicare/commercial insurance. Colon cancer comprised 41% of primary diagnoses. Twenty-eight percent of cases were nonelective, more likely to have Medicaid/underinsured (21% versus 7%, P < 0.001), and had higher utilization of postdischarge cost-drivers. Ninety-day EoC per case cost was 66% higher for emergent versus elective cases. Of eligible emergency cancer cases, 43% (40/93) had undergone prior colonoscopy within 10 y. For patients with colon cancer, 90-d EoC per case was 39% higher for emergent versus elective cases. CONCLUSIONS: Emergency MB-EoC cases disproportionally contribute to higher 90-d care utilization and costs. Efforts to increase screening colonoscopy in appropriate populations may have a substantial impact on MB-EoC costs.

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.

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.

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.

International Delphi Expert Consensus on Safe Return to Surgical and Endoscopic Practice: From the Coronavirus Global Surgical Collaborative.

OBJECTIVE: The aim of this work is to formulate recommendations based on global expert consensus to guide the surgical community on the safe resumption of surgical and endoscopic activities. BACKGROUND: The COVID-19 pandemic has caused marked disruptions in the delivery of surgical care worldwide. A thoughtful, structured approach to resuming surgical services is necessary as the impact of COVID-19 becomes better controlled. The Coronavirus Global Surgical Collaborative sought to formulate, through rigorous scientific methodology, consensus-based recommendations in collaboration with a multidisciplinary group of international experts and policymakers. METHODS: Recommendations were developed following a Delphi process. Domain topics were formulated and subsequently subdivided into questions pertinent to different aspects of surgical care in the COVID-19 crisis. Forty-four experts from 15 countries across 4 continents drafted statements based on the specific questions. Anonymous Delphi voting on the statements was performed in 2 rounds, as well as in a telepresence meeting. RESULTS: One hundred statements were formulated across 10 domains. The statements addressed terminology, impact on procedural services, patient/staff safety, managing a backlog of surgeries, methods to restart and sustain surgical services, education, and research. Eighty-three of the statements were approved during the first round of Delphi voting, and 11 during the second round. A final telepresence meeting and discussion yielded acceptance of 5 other statements. CONCLUSIONS: The Delphi process resulted in 99 recommendations. These consensus statements provide expert guidance, based on scientific methodology, for the safe resumption of surgical activities during the COVID-19 pandemic.

Non-elective paraesophageal hernia repair: surgical approaches and short-term outcomes.

BACKGROUND: The majority of laparoscopic paraesophageal hernia (PEH) repairs are performed electively. We aimed to investigate the frequency of non-elective laparoscopic (MIS) PEH repair and compare 30-day outcomes to elective MIS repairs and non-elective open repairs. We hypothesized that an increasing percentage of non-elective PEH repairs would be performed laparoscopically and that this population would have improved outcomes compared to non-elective open PEH counterparts. METHODS: The 2011-2016 NSQIP PUFs were used to identify patients who underwent PEH repair. Case status was classified as open vs. MIS and elective versus non-elective. Preoperative patient characteristics, operative details, discharge destination, and 30-day postoperative complication rates were compared. Logistic regression was used to examine the impact of case status on 30-day mortality. RESULTS: We identified 20,010 patients who underwent PEH. There were an increasing number of MIS PEH repairs in NSQIP between 2011 and 2016. Non-elective repairs were performed in 2,173 patients and 73.4% of these were completed laparoscopically. Elective MIS patients were younger, had a higher BMI, and were more likely to be functionally independent (p < 0.01) than their non-elective counterparts. Non-elective MIS patients had a higher wound class and ASA class compared to their elective counterparts. Compared to elective MIS cases, non-elective MIS PEH repair was associated with increased odds of mortality, even after controlling for patient characteristics (OR = 1.76, p = 0.02). There was no statistically significant difference in mortality for non-elective MIS vs. non-elective open PEH repair. There is an increase in non-elective PEH repairs recorded in NSQIP over time studied. CONCLUSIONS: The population undergoing non-elective MIS PEH repairs is different from their elective MIS counterparts and experience a higher postoperative mortality rate. While the observed increased utilization of MIS techniques in non-elective PEH repairs likely provides benefits for the patient, there remain differences in outcomes for these patients compared to elective PEH repairs.

Impact of Multidisciplinary Audit of Enhanced Recovery After Surgery (ERAS)® Programs at a Single Institution.

BACKGROUND: As Enhanced Recovery After Surgery (ERAS®) programs expand across numerous subspecialties, growth and sustainability on a system level becomes increasingly important and may benefit from reporting multidisciplinary and financial data. However, the literature on multidisciplinary outcome analysis in ERAS is sparse. This study aims to demonstrate the impact of multidisciplinary ERAS auditing in a hospital system. Additionally, we describe developing a financial metric for use in gaining support for system-wide ERAS adoption and sustainability. METHODS: Data from HPB, colorectal and urology ERAS programs at a single institution were analyzed from a prospective ERAS Interactive Audit System (EIAS) database from September 2015 to June 2019. Clinical 30-day outcomes for the ERAS cohort (n = 1374) were compared to the EIAS pre-ERAS control (n = 311). Association between improved ERAS compliance and improved outcomes were also assessed for the ERAS cohort. The potential multidisciplinary financial impact was estimated from hospital bed charges. RESULTS: Multidisciplinary auditing demonstrated a significant reduction in postoperative length of stay (LOS) (1.5 days, p < 0.001) for ERAS patients in aggregate and improved ERAS compliance was associated with reduced LOS (coefficient - 0.04, p = 0.004). Improved ERAS compliance in aggregate also significantly associated with improved 30-day survival (odds ratio 1.04, p = 0.001). Multidisciplinary analysis also demonstrated a potential financial impact of 44% savings (p < 0.001) by reducing hospital bed charges across all specialties. CONCLUSIONS: Multidisciplinary auditing of ERAS programs may improve ERAS program support and expansion. Analysis across subspecialties demonstrated associations between improved ERAS compliance and postoperative LOS as well as 30-day survival, and further suggested a substantial combined financial impact.

Modified Broström-Gould With Gracilis Autograft Augmentation Surgery and Accelerated Noncasted Rehabilitation in High Demand Patients With Lateral Ankle Instability.

Lateral ankle instability that has failed conservative management can be physically debilitating. Good outcomes are obtained from Broström-Gould augmented repair techniques, however there are few studies evaluating the use of a gracilis autograft augmentation coupled with an accelerated rehabilitation program in high functional demand patients. We believe that the modified Broström-Gould technique utilizing a Gracilis autograft will provide significant improvements in stability while maintaining normal ankle biomechanics in young, high demand patients. The prospective cohort study involved 19 patients (20 ankles) who underwent surgery for chronic lateral ankle instability by a single surgeon, at a single institution between October 2014 and April 2016. Patients were followed for 33.8 ± 11.7 (range 12-48) months. Patients were assessed both pre- and postoperatively for talar tilt angle radiographically and with both American Orthopaedic Foot and Ankle Society Ankle and Hindfoot scores and Karlsson-Peterson scores. A Tegner activity score was taken at the last follow-up. The mean American Orthopaedic Foot and Ankle Society score increased from 68.85 ± 10.57 to 91.56 ± 5.31 points (p < .01) and mean Karlsson-Peterson score increased from 50.9 ± 15.53 to 88.11 ± 8.64 points (p value <.01) when compared preoperatively to mean postoperative follow-up of 33.8 months. Tegner activity score was 7.05 ± 0.89 at last follow-up. The technique was found to be effective in treating chronic lateral ankle instability and in combination with an accelerated rehabilitation protocol, patients returned to their premorbid level of activity with improved stability and no significant effect on donor graft site morbidity.

Use of minimally invasive surgery in emergency general surgery procedures.

BACKGROUND: Minimally invasive surgery (MIS) has demonstrated superior outcomes in many elective procedures. However, its use in emergency general surgery (EGS) procedures is not well characterized. The purpose of this study was to examine the trends in utilization and outcomes of MIS techniques in EGS over the past decade. METHODS: The 2007-2016 ACS-NSQIP database was utilized to identify patients undergoing emergency surgery for four common EGS diagnoses: appendicitis, cholecystitis/cholangitis, peptic ulcer disease, and small bowel obstruction. Trends over time were described. Preoperative risk factors, operative characteristics, outcomes, morbidity, and trends were compared between MIS and open approaches using univariate and multivariate analysis. RESULTS: During the 10-year study period, 190,264 patients were identified. The appendicitis group was the largest (166,559 patients) followed by gallbladder disease (9994), bowel obstruction (6256), and peptic ulcer disease (366). Utilization of MIS increased over time in all groups (p < 0.001). There was a concurrent decrease in mean days of hospitalization in each group: appendectomy (2.4 to 2.0), cholecystectomy (5.7 to 3.2), peptic ulcer disease (20.3 to 11.7), and bowel obstruction (12.9 to 10.5); p < 0.001 for all. On multivariate analysis, use of MIS techniques was associated with decreased odds of 30-day mortality, surgical site infection, and length of hospital stay in all groups (p < 0.001). CONCLUSIONS: Use of MIS techniques in these four EGS diagnoses has increased in frequency over the past 10 years. When adjusted for preoperative risk factors, use of MIS was associated with decreased odds of wound infection, death, and length of stay. Further studies are needed to determine if increased access to MIS techniques among EGS patients may improve outcomes.

SAGES primer for taking care of yourself during and after the COVID-19 crisis.

COVID-19 is a pandemic which has affected almost every aspect of our life since starting globally in November 2019. Given the rapidity of spread and inadequate time to prepare for record numbers of sick patients, our surgical community faces an unforeseen challenge. SAGES is committed to the protection and care of patients, their surgeons and staff, and all who are served by the medical community at large. This includes physical health, mental health, and well-being of all involved. The fear of the unknown ahead can be paralyzing. International news media have chronicled the unthinkable situations that physicians and other health care providers have been thrust into as a result of the COVID-19 pandemic. These situations include making life or death decisions for patients and their families regarding use of limited health care resources. It includes caring for patients with quickly deteriorating conditions and limited treatments available. Until recently, these situations seemed far from home, and now they are in our own hospitals. As the pandemic broadened its reach, the reality that we as surgeons may be joining the front line is real. It may be happening to you now; it may be on the horizon in the coming weeks. In this context, SAGES put together this document addressing concerns on clinician stressors in these times of uncertainty. We chose to focus on the emotional toll of the situation on the clinician, protecting vulnerable persons, reckoning with social isolation, and promoting wellness during this crisis. At the same time, the last part of this document deals with the "light at the end of the tunnel," discussing potential opportunities, lessons learned, and the positives that can come out of this crisis.

The next step in surgical quality improvement: outcome situational awareness

Summary: A similar theme unites proposed solutions for stagnant improvement in outcomes and rising health care costs: eliminate unnecessary variation in the care of surgical patients. While large quality-improvement projects like the Americal College of Surgeons National Surgical Quality Improvement Program have historically led to improved patient outcomes at the hospital level, the next step in surgical quality improvement is to eliminate unnecessary variation at the level of the individual surgeon. Critical examination of individualized clinical, financial and patient-reported outcomes ­ outcome situational awareness ­ along with peer group comparison will help surgeons to identify variation in patient care. We are piloting an interactive software platform at our institution to provide information on individualized clinical, financial and patient-reported outcomes in real time through automatic data population of a central REDCap database. These individualized data along with peer group comparison allow surgeons to objectively determine areas of potential improvement.

The quadriceps active ratio: a dynamic MRI-based assessment of patellar height.

INTRODUCTION: Patella alta (PA) is one of the primary correctable risk factors for patellofemoral instability (PFI). Both an accurate diagnosis of PA and a clinically relevant target for correction are necessary for optimal treatment. An ideal test for PA should relate the position of the patella to the femur rather than tibia, should do so with the quadriceps contracted and the patellar tendon under tension and should have good sensitivity and specificity. None of the currently used radiographic tests PA meet these criteria, most of which are based on the position of the patella relative to the tibia with diagnostic cutoffs based on 2 standard deviations from the mean rather than optimal sensitivity and specificity. The authors describe the quadriceps active ratio (Q+R), an MRI-based assessment of PA based on patellofemoral contact under quadriceps activated with a cutoff based on optimal sensitivity a specificity for PFI. MATERIAL-METHODS: Ninety-four participants investigated for knee pain or instability with a clinically indicated MRI were recruited. Routine MRI sequences were obtained, with the addition of a quadriceps contracted sagittal T1-weighted sequence. Participants presenting with PFI were identified. Those with trochlear dysplasia were identified and excluded from analysis so that patellar height could be assessed against PFI without being confounded by trochlear dysplasia. Q+R and patellotrochlear index (PTI) were calculated from the remaining 78 scans by 3 consultant orthopaedic surgeons at three time points. In 54 of these cases, a lateral radiograph was available from which the Insall-Salvati, modified Insall-Salvati, Caton-Deschamps and Blackburn-Peel ratios were also calculated. Intra- and inter-observer reliability was assessed for the Q+R. A cutoff value for the Q+R based on optimal sensitivity and specificity for the diagnosis of PFI was calculated from receiver-operator characteristic (ROC) curves and compared to the PTI. The cutoff for the Q+R was compared for sensitivity and specificity for the diagnosis of PFI against the radiographic ratios. RESULTS: The Q+R had satisfactory or better ICC values across time points and surgeons. The Q+R was superior to the PTI on area under curve ROC analysis (0.76 vs 0.74). A cutoff value of 0.12 for the Q+R gave sensitivity of 79% and specificity of 55% for the diagnosis of PFI. The radiographic indices were generally insensitive for this diagnosis of PFI with sensitivities ranging from 0-66%. CONCLUSION: The Q+R is a reliable diagnostic test for patellar height assessment, showing good intra- and inter-rater consistency, and greater diagnostic accuracy than the PTI. A Q+R value of 0.12 is a good test for clinically significant PA. Of the radiographic indices, the Insall-Salvati ratio had the best diagnostic accuracy.

Multicenter, Prospective, Longitudinal Study of the Recurrence, Surgical Site Infection, and Quality of Life After Contaminated Ventral Hernia Repair Using Biosynthetic Absorbable Mesh: The COBRA Study.

OBJECTIVE: The aim of the study was to evaluate biosynthetic absorbable mesh in single-staged contaminated (Centers for Disease Control class II and III) ventral hernia (CVH) repair over 24 months. BACKGROUND: CVH has an increased risk of postoperative infection. CVH repair with synthetic or biologic meshes has reported chronic biomaterial infections and high hernia recurrence rates. METHODS: Patients with a contaminated or clean-contaminated operative field and a hernia defect at least 9 cm had a biosynthetic mesh (open, sublay, retrorectus, or intraperitoneal) repair with fascial closure (n = 104). Endpoints included overall Kaplan-Meier estimates for hernia recurrence and postoperative wound infection rates at 24 months, and the EQ-5D and Short Form 12 Health Survey (SF-12). Analyses were conducted on the intent-to-treat population, and health outcome measures evaluated using paired t tests. RESULTS: Patients had a mean age of 58 years, body mass index of 28 kg/m, 77% had contaminated wounds, and 84% completed 24-months follow-up. Concomitant procedures included fistula takedown (n = 24) or removal of infected previously placed mesh (n = 29). Hernia recurrence rate was 17% (n = 16). At the time of CVH repair, intraperitoneal placement of the biosynthetic mesh significantly increased the risk of recurrences (P ≤ 0.04). Surgical site infections (19/104) led to higher risk of recurrence (P < 0.01). Mean 24-month EQ-5D (index and visual analogue) and SF-12 physical component and mental scores improved from baseline (P < 0.05). CONCLUSIONS: In this prospective longitudinal study, biosynthetic absorbable mesh showed efficacy in terms of long-term recurrence and quality of life for CVH repair patients and offers an alternative to biologic and permanent synthetic meshes in these complex situations.

Trends in parastomal hernia repair in the United States: a 14-y review.

BACKGROUND: Parastomal hernia is the most common complication after stoma creation. Parastomal hernias can create significant morbidity, including patient discomfort, small bowel obstruction, and need for emergency surgery. We examined national trends in parastomal hernia repair (PHR) including annual frequency of procedure, patient characteristics, and same-admission complications. MATERIALS AND METHODS: The 1998-2011 Nationwide Inpatient Sample was used to identify patients who underwent a PHR (International Classification of Disease, Ninth Edition, Procedure Code [ICD-9 PR] 46.42). PHRs were classified as PHR with concurrent resiting (ICD-9 PR 46.43), PHR with concurrent ostomy reversal (ICD-9 PR 46.52 or 46.51), or primary PHR. Patient characteristics were collected. Complications, length of stay, cost and inpatient mortality were identified. RESULTS: The estimated number of annual PHRs increased from 4150 to 7623 (P ≤ 0.01) for a total of 73,393 repairs. Thirty percent underwent a concurrent stoma reversal and 10% underwent a resiting. There was an upward trend in number of patients with ≥3 Elixhauser comorbidities (17%-44%, P < 0.01). Length of stay remained steady, with a median of 6.3 d and in-hospital annual mortality ranged from 1.8% to 3.9%. Mortality and emergency admission status were highest for patients who underwent primary PHR. CONCLUSIONS: The incidence of PHR nationwide is increasing and more than half of patients undergo primary repair. Although the surgical focus has moved toward prevention, parastomal hernia is a persistent complication of stoma creation. Further exploration is warranted to determine contributing factors to the observed increase in PHR and changes in surgical technique.

Emergency general surgery transfers in the United States: a 10-year analysis.

BACKGROUND: Emergency general surgery (EGS) admissions account for more than three million hospitalizations in the US annually; and interhospital transfers (IHTs) are costly. We aimed to better understand the population of transferred EGS patients and their subsequent care in a nationally representative sample. METHODS: Using the 2002-2011 Nationwide Inpatient Sample, we identified patients aged ≥18 years with an EGS noncardiovascular principal diagnosis who were transferred from another hospital with urgent or emergent admission status. Patient demographics, hospitalization characteristics, rates of operation, and mortality were identified. Procedure codes were classified into surgery and procedures based on the HCUP Surgery Flag. RESULTS: We identified an estimated 525,913 EGS admissions transferred from another acute care hospital. The mean age was 60 years, 51% were female, and >50% were Medicare patients. The rate of EGS IHTs increased while mortality decreased. Surgery was required for only 33% of transferred patients. The most common surgeries were laparoscopic cholecystectomy, lysis of adhesions, and wound debridement. The median length of stay was 4.4 days, 92% of patients were cared for in urban hospitals, and >50% in teaching hospitals. CONCLUSIONS: The percent of patients with an EGS diagnosis requiring IHT is increasing, which may reflect a trend toward regionalization of EGS. Transfers require significant resources and may delay care. More than half of the EGS patients did not require surgical intervention. Future studies to identify populations who benefit from IHT and ideal timing of transfer can establish opportunities for optimizing resource utilization and patient outcomes.

In Vivo Arthroscopic Temperatures: A Comparison Between 2 Types of Radiofrequency Ablation Systems in Arthroscopic Anterior Cruciate Ligament Reconstruction-A Randomized Controlled Trial.

PURPOSE: To compare a plasma ablation device with a standard ablation device in anterior cruciate ligament (ACL) reconstruction to determine which system is superior in terms of intra-articular heat generation and diathermy efficiency. METHODS: This was a prospective, randomized controlled trial. The inclusion criteria were adult patients undergoing primary ACL reconstruction. Patients were randomized preoperatively to the standard ablation group or the plasma ablation group. A thermometer was inserted into the inferior suprapatellar pouch, and the temperature, time, and duration of radiofrequency ablation were measured continually. RESULTS: No significant differences were found between the standard ablation system and the plasma ablation system for maximum temperature (29.77°C and 29.34°C, respectively; P = .95), mean temperature (26.16°C and 26.99°C, respectively; P = .44), minimum temperature (22.66°C and 23.94°C, respectively; P = .54), and baseline temperature (26.80°C and 27.93°C, respectively; P = .35). Similarly, no significant differences were found for operative time (82.90 minutes and 80.50 minutes, respectively; P = .72) and mean diathermy activation times (2.6 minutes for both systems; P = .90). The between-system coefficient of variation for the measured parameters ranged from 0.12% to 3.69%. No intra-articular readings above the temperature likely to damage chondrocytes were recorded. The mean irrigation fluid temperature had a significant correlation with the maximum temperature reached during the procedure (Spearman rank correlation, r = 0.87; P < .01). CONCLUSIONS: No difference in temperature was observed between the standard ablation and plasma ablation probes during ACL reconstruction. Temperatures did not exceed critical temperatures associated with chondrocyte death. LEVEL OF EVIDENCE: Level I, randomized controlled trial.

Acuity, outcomes, and trends in the transfer of surgical patients: a national study.

INTRODUCTION: With the regionalization of surgical care, reduction in the rural workforce, rising healthcare costs, and increasing focus on surgical outcomes, appropriate transfer of surgical patients is an increasingly important aspect of health care. This study examines patients transferred for surgical intervention through a national sample. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was queried from 2005 to 2012 for surgery patients who were transferred from an outside hospital or emergency department (ED) and compared patients undergoing surgery without transfer. Patients were divided into two time periods (TP): 2005-2008 (TP1) and 2008-2012 (TP2) for analysis; patient characteristics and top CPT codes for each TP were collected. Univariate analysis and matched cohorts were used to compare the groups. RESULTS: Overall, 61,204 patients were transferred and underwent surgery. The rate of transferred surgery patients increased from 3.2% in TP1 to 4.5% in TP2 (p < 0.0001). Compared to non-transferred patients, transferred patients had higher rates of diabetes (23.4 vs. 17.6%, p < 0.0001), tobacco use (27.9 vs. 20.3%, p < 0.0001), Charlson comorbidity index (mean score 1.5 vs. 0.8, p < 0.0001), preoperative sepsis (32.0 vs. 9.4%, p < 0.0001), and need for emergent surgery (41.3 vs. 14.4%, p < 0.0001). From TP1 to TP2, there was an increase in transferred patients who were obese (33.9-36.4%, p < 0.0001) and had emergent transfers (39.6-41.8%, p < 0.0001), with a decrease in diabetic patients (24.7-23.1%, p < 0.0001). From TP1 to TP2, transferred patients had more minor complications (17.7-31.0%, p < 0.0001), but fewer major complications (32.1-23.9%, p < 0.0001) and lower 30-day mortality (11.8-8.1%, p < 0.0001). CONCLUSIONS: Patients transferred for surgery represent a higher acuity population than non-transferred patients, and the number of transfers continues to rise. Even when matched by comorbidities, transferred patients have worse outcomes. Surgical sub-specialization and physician tiering may complicate future transfer practices. Efficient transfers, effective physician communication, and ready availability of medical records are critical in improving patient transfers.
