Analysis of perinatal outcomes for emergency cervical cerclage in singleton pregnancies at 24-28 weeks of gestation.

BACKGROUND: Cervical cerclage is the only effective treatment for cervical insufficiency, effectively preventing late miscarriage and preterm birth. The effectiveness and safety of emergency cervical cerclage (ECC) as an emergency treatment when the cervix is already dilated or when there is protrusion of the fetal membranes into the vagina remain controversial, especially in pregnancies at 24-28 weeks when the fetus is viable. There is still no consensus on whether emergency cervical cerclage should be performed in such cases. PURPOSE: To investigate the effectiveness and safety of emergency cervical cerclage in singleton pregnant women at 24-28 weeks of gestation. METHODS: This study employed a single-center prospective cohort design, enrolling singleton pregnant women at 24-28 weeks of gestation with ultrasound or physical examination indicating cervical dilation or even membrane protrusion. Emergency cervical cerclage was compared with conservative treatment. The primary endpoints included a comprehensive assessment of perinatal pregnancy loss, significant neonatal morbidity, and adverse neonatal outcomes. Secondary endpoints included prolonged gestational age, preterm birth, neonatal hospitalization rate, premature rupture of membranes, and intrauterine infection/chorioamnionitis. RESULTS: From June 2021 to March 2023, a total of 133 pregnant women participated in this study, with 125 completing the trial, and were allocated to either the Emergency Cervical Cerclage (ECC) group (72 cases) or the conservative treatment group (53 cases) based on informed consent from the pregnant women. The rate of adverse neonatal outcomes was 8.33% in the ECC group and 26.42% in the conservative treatment (CT) group, with a statistically significant difference (P = 0.06). There were no significant differences between the two groups in terms of perinatal pregnancy loss and significant neonatal morbidity. The conservative treatment group had a mean prolonged gestational age of 63.0 (23.0, 79.5) days, while the ECC group had 84.0 (72.5, 89.0) days, with a statistically significant difference between the two groups (P < 0.001). Compared with CT group, the ECC group showed a significantly reduced incidence of preterm birth before 28 weeks, 32 weeks, and 34 weeks, with statistical significance (P = 0.046, 0.007, 0.001), as well as a significantly decreased neonatal hospitalization rate (P = 0.013, 0.031). Additionally, ECC treatment did not increase the risk of preterm premature rupture of membranes or intrauterine infection/chorioamnionitis, with no statistically significant differences (P = 0.406, 0.397). CONCLUSION: In singleton pregnant women with cervical insufficiency at 24-28 weeks of gestation, emergency cervical cerclage can reduce adverse neonatal pregnancy outcomes, effectively prolong gestational age, decrease preterm births before 28 weeks, 32 weeks, and 34 weeks, lower neonatal hospitalization rates, and does not increase the risk of preterm premature rupture of membranes or intrauterine infection/chorioamnionitis.

Geographic Variation in the Utilization of and Mortality After Emergency General Surgery Operations in the Northeastern and Southeastern United States.

OBJECTIVE: To define geographic variations in emergency general surgery (EGS) care, we sought to determine how much variability exists in the rates of EGS operations and subsequent mortality in the Northeastern and Southeastern United States (US). SUMMARY BACKGROUND DATA: While some geographic variations in healthcare are normal, unwarranted variations raise questions about the quality, appropriateness, and cost-effectiveness of care in different areas. METHODS: Patients ≥18 years who underwent 1 of 10 common EGS operations were identified using the State Inpatient Databases (2011-2012) for 6 states, representing Northeastern (New York) and Southeastern (Florida, Georgia, Kentucky, North Carolina, Mississippi) US. Geographic unit of analysis was the hospital service area (HSA). Age-standardized rates of operations and in-hospital mortality were calculated and mapped. Differences in rates across geographic areas were compared using the Kruskal-Wallis test, and variance quantified using linear random-effects models. Variation profiles were tabulated via standardized rates of utilization and mortality to compare geographically heterogenous areas. RESULTS: 227,109 EGS operations were geospatially analyzed across the 6 states. Age-standardized EGS operation rates varied significantly by region (Northeast rate of 22.7 EGS operations per 10,000 in population versus Southeast 21.9; P < 0.001), state (ranging from 9.9 to 29.1; P < 0.001), and HSA (1.9-56.7; P < 0.001). The geographic variability in age-standardized EGS mortality rates was also significant at the region level (Northeast mortality rate 7.2 per 1000 operations vs Southeast 7.4; P < 0.001), state-level (ranging from 5.9 to 9.0 deaths per 1000 EGS operations; P < 0.001), and HSA-level (0.0-77.3; P < 0.001). Maps and variation profiles visually exhibited widespread and substantial differences in EGS use and morality. CONCLUSIONS: Wide geographic variations exist across 6 Northeastern and Southeastern US states in the rates of EGS operations and subsequent mortality. More detailed geographic analyses are needed to determine the basis of these variations and how they can be minimized.

Natural history, growth rates, and treatment of popliteal artery aneurysms.

BACKGROUND: The natural history of a cohort of patients monitored for popliteal artery aneurysms (PAAs) has not been well described. A prevailing uncertainty exists regarding the optimal surveillance strategies and timing of treatment. The primary aim of the present study was to describe the care trajectory of all patients with PAAs identified at two tertiary vascular centers, both in surveillance and eventually treated. The secondary aim was to define the PAA growth rates. METHODS: A retrospective, multicenter cohort study was performed of all patients with PAAs at two vascular centers in two countries (Sweden, 2009-2016; New Zealand, 2009-2017). Data were collected from electronic medical records regarding the comorbidities, treatment, and outcomes and analyzed on a patient- and extremity-specific level. Treatment was indicated at the occurrence of emergent symptoms or considered at a PAA threshold of >2 cm. The PAAs were divided into small (≤15 mm) and large (>15 mm) aneurysms. The mean surveillance follow-up was 5.1 years. RESULTS: Most of the 241 identified patients (397 limbs) with a diagnosis of PAAs had bilateral aneurysms (n = 156). Most patients were treated within the study period (163 of 241; 68%), and one half of the diagnosed extremities with PAA had been treated (54%; 215 of 397). Among those who had undergone elective repair, treatment had usually occurred within 1 year after the diagnosis (66%; 105 of 158). More small PAAs were detected in the group that had required emergent repair compared with elective repair (6 of 57 [11%] vs 12 of 158 [8%]; P < .001). No differences were found in the mean diameters between the elective and emergent groups (30.1 mm vs 32.2 mm; P = .39). Growth was recorded in 110 PAAs and on multivariate analysis was associated with a larger index diameter (odds ratio, 1.138; 95% confidence interval, 1.040-1.246; P = .005) and a concurrent abdominal aortic aneurysm (odds ratio, 2.553; 95% confidence interval, 1.018-6.402; P = .046). CONCLUSIONS: The present cohort of patients represented a true contemporary clinical setting of monitored PAAs and showed that most of these patients will require elective repair, usually within 1 year. The risk of emergent repair is not negligible for patients with smaller diameter PAAs. However, the optimal selection strategy for preventive early repair is still unknown. Future morphologic studies are needed to support the development of individualized surveillance protocols.

Prospective Evaluation of Health Literacy and Its Impact on Outcomes in Emergency General Surgery.

BACKGROUND: Health literacy (HL) is an important component of national health policy. The aim of our study was to assess the prevalence of low HL (LHL) and determine its impact on outcomes after emergency general surgery (EGS). METHODS: We performed a (2016-2017) prospective cohort analysis of adult EGS patients. HL was assessed using the Short Assessment of HL score. LHL was defined as Short Assessment of HL score <14. Outcomes were the prevalence of LHL, compliance with medications, wound/drain care, 30-d complications, 30-d readmission, and time to resuming activities of daily living. RESULTS: We enrolled 900 patients. The mean age was 43 ± 11 y. Overall, 22% of the patients had LHL. LHL patients were more likely to be Hispanics (59% versus 15%, P < 0.01), uninsured (50% versus 20%, P < 0.01), have lower socioeconomic status (80% versus 40%, P < 0.02), and are less likely to have completed college (5% versus 60%, P < 0.01) compared with HL patients. On regression analysis, LHL was associated with lower medication compliance (OR: 0.81, [0.4-0.9], P = 0.02), inadequate wound/drain care (OR: 0.75, [0.5-0.8], P = 0.01), 30-d complications (OR: 1.95, [1.3-2.5], P < 0.01), and 30-d readmission (OR: 1.51, [1.2-2.6], P = 0.02). The median time of resuming activities of daily living was longer in patients with LHL than HL patients (4 d versus 7 d, P < 0.01). CONCLUSIONS: One in five patients undergoing EGS has LHL. LHL is associated with decreased compliance with discharge instructions, medications, and wound/drain care. Health literacy must be taken into account when discussing the postoperative plan and better instruction is needed for patients with LHL. LEVEL OF EVIDENCE: Level III. STUDY TYPE: Prognostic.

Emergency General Surgery and the Gallbladder: The Affordable Care Act's Impact on Practice Patterns.

BACKGROUND: Gallbladder disease frequently requires emergency general surgery (EGS). The Affordable Care Act (ACA) mandated health insurance coverage for all with the intent to improve access to care and decrease morbidity, mortality, and costs. We hypothesize that after the ACA open-enrollment in 2014 the number of EGS cholecystectomies decreased as access to care improved with a shift in EGS cholecystectomies to teaching institutions. METHODS: A retrospective review of the National Inpatient Sample Database from 2012 to quarter 3 of 2015 was performed. Patients age 18-64, with a nonelective admission for gallbladder disease based on ICD-9 codes, were collected. Outcomes measured included cholecystectomy, complications, mortality, and wage index-adjusted costs. The effect of the ACA was determined by comparing preACA to postACA years. RESULTS: 189,023 patients were identified. In the postACA period the payer distribution for admissions decreased for Self-pay (19.3% to 13.6%, P < 0.001), Medicaid increased (26.3% to 34.0%, P < 0.001) and Private insurance was unchanged (48.6% to 48.7%, P = 0.946). PostACA, admissions to teaching hospitals increased across all payer types, EGS cholecystectomies decreased, while complications increased, and mortality was unchanged. Median costs increased significantly for Medicaid and Private insurance while Self-pay was unchanged. Based on adjusted DID analyses for Insured compared to Self-pay patients, EGS cholecystectomies decreased (-2.7% versus -1.21%, P = 0.033) and median cost increased more rapidly (+$625 versus +$166, P = 0.017). CONCLUSIONS: The ACA has changed EGS, shifting the majority of patients to teaching institutions despite insurance type and decreasing the need for EGS cholecystectomy. The trend toward higher complication rate with increased overall cost requires attention.

Surgical Diseases are Common and Complicated for Criminal Justice Involved Populations.

BACKGROUND: At any given time, almost 2 million individuals are in prisons or jails in the United States. Incarceration status has been associated with disproportionate rates of cancer and infectious diseases. However, little is known about the burden emergency general surgery (EGS) in criminal justice involved (CJI) populations. MATERIALS AND METHODS: The California Office of Statewide Health Planning and Development (OSHPD) database was used to evaluate all hospital admissions with common EGS diagnoses in CJI persons from 2012-2014. The population of CJI individuals in California was determined using United States Bureau of Justice Statistics data. Primary outcomes were rates of admission and procedures for five common EGS diagnoses, while the secondary outcome was probability of complex presentation. RESULTS: A total of 4,345 admissions for CJI patients with EGS diagnoses were identified. The largest percentage of EGS admissions were with peptic ulcer disease (41.0%), followed by gallbladder disease (27.5%), small bowel obstruction (14.0%), appendicitis (13.8%), and diverticulitis (10.5%). CJI patients had variable probabilities of receipt of surgery depending on condition, ranging from 6.2% to 90.7%. 5.6% to 21.0% of admissions presented with complicated disease, the highest being with peptic ulcer disease and appendicitis. CONCLUSION: Admissions with EGS diagnoses were common and comparable to previously published rates of disease in general population. CJI individuals had high rates of complicated presentation, but low rates of surgical intervention. More granular evaluation of the burden and management of these common, morbid, and costly surgical diagnoses is essential for ensuring timely and quality care delivery for this vulnerable population.

The Burden of Emergency Abdominal Surgery Heavily Outweighs Elective Procedures in KwaZulu-Natal Province, South Africa.

BACKGROUND: South Africa is a middle-income country with major discrepancies in wealth and access to care. There is a significant burden of surgical disease and limited access to quality health care for a large proportion of the population. This article quantifies the burden of abdominal surgery over a 6-month period in KwaZulu-Natal (KZN) province and quantifies the emergency to elective (Ee) ratio for these operations. METHODS: This study describes the abdominal operations conducted at all regional and tertiary hospitals in the public health sector of KZN province for the period of 1 July to December 31, 2015. Operations performed were tabulated in a spreadsheet and categorized as elective, emergency, and trauma. They were further subdivided by anatomical region and by specific predetermined procedures. Uncertain criteria were clarified using a modified Delphi discussion. The Ee ratio was determined using the recently described technique. RESULTS: Between June, 1st and December 31, 2015, of 13,282 operations, there were 4580 (34.5%) elective operations, 7777 (58.6%) emergency operations, and 925 (6.9%) trauma-related operations. A total of 5630 abdominal operations were performed of which 2949 were emergency procedures. There were 660 trauma-related abdominal procedures and 2021 elective procedures. There was a heavy weighting toward emergency surgeries with an Ee ratio of 145 for abdominal surgery. The previous sub-Saharan African ratio was estimated to be 62.6. CONCLUSIONS: An overview of abdominal surgery in KZN reveals a high ratio of emergency to elective surgery. This suggests that the current primary health care program is failing to detect and treat acute surgical disease timeously.

High Acuity of Postoperative Consults to Emergency General Surgery at an Urban Safety Net Hospital.

BACKGROUND: Emergency general surgery (EGS) has high rates of morbidity, mortality, and readmission. Therefore, it might be expected that an EGS service fields many consultations for postoperative patients. However, with the known overutilization of emergency department visits for nonurgent conditions, we hypothesized most postoperative consults received by an EGS service would be nonurgent and could be appropriately managed as an outpatient. METHODS: We reviewed all EGS consults at a single urban safety net hospital over a 12-month period, screening for patients who had undergone surgery in the previous 12 mo. This included consultations from the emergency room and inpatient setting. Demographics, admission status, procedures performed, and other details were abstracted from the chart and Vizient reports. Consultation questions were categorized and then reviewed by an expert panel to determine if conditions could have been managed as an outpatient. RESULTS: The EGS service received a total of 1112 consults, with 99 (9%) for a postoperative condition. Overall, 85% of postoperative consults were admitted after consultation, 19% underwent surgery and 21% underwent a procedure with gastroenterology or interventional radiology. Expert review classified slightly over one-third (36%) of consults as nonurgent. CONCLUSIONS: Most postoperative consults seen at our urban safety net hospital represent true morbidity that required admission, intervention, or surgery. Despite this high acuity, one-third of postoperative consults could have been managed as an outpatient. Efforts to improve discharge instructions and set patient expectations could limit unnecessary postoperative emergency department visits.

A Flat Inferior Vena Cava on Computed Tomography Is Associated With Worse Outcomes in Emergency General Surgery.

BACKGROUND: Several trauma studies have shown that a "flat" inferior vena cava (IVC) is associated with poor clinical outcomes, including hypovolemic shock, major bleeding, transfusions and mortality. These studies utilize IVC measurements on computed tomography (CT) scans, and rarely include emergency general surgery patients. We examine the association between IVC flatness and clinical outcomes in a series of patients with perforated viscus. MATERIALS AND METHODS: Medical records at an academic hospital were reviewed of adults with perforated viscus. Patients who underwent laparotomy or laparoscopy were included if they underwent CT within 12 h prior to incision time. Perforated appendicitis was excluded. A ratio was calculated of the transverse to anterior-posterior diameter of the IVC at 3 locations, then averaged. Clinical outcomes were analyzed by the average IVC ratio. RESULTS: A total of 83 patients were included. Using binomial regression, the average IVC ratio significantly correlated with ICU admission (OR 3.6, 95% CI 1.2 to 11) and acute kidney injury (OR 2.3, 95% CI 1.0 to 5.3), but not postoperative shock (OR 1.2, 95% CI 0.56 to 2.6). CONCLUSIONS: A flat IVC on CT prior to an operation for perforated viscus was associated with worse outcomes, including increased rate of ICU admission and acute kidney injury. More outcomes research is needed to assess the potential role of IVC assessment in preoperative resuscitation.

Editor's Choice - Systematic Review and Meta-Analysis of the Effect of Weekend Admission on Outcomes for Ruptured Abdominal Aortic Aneurysms: A Call for an Equitable Seven Day Vascular Service.

OBJECTIVE: "The weekend effect" of higher patient mortality when presenting at a weekend compared with a weekday has been established for several conditions. The aim of this study was to investigate whether a weekend effect exists for the emergency condition of ruptured abdominal aortic aneurysm. DATA SOURCES: A review of the literature was conducted in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines (PROSPERO registration number CRD42020157484). MEDLINE, EMBASE and CINAHL were searched using the Healthcare Databases Advanced Search interface developed by NICE. REVIEW METHODS: The prognostic factor of interest was weekend admission. The primary outcome of interest was all cause peri-operative mortality, with a secondary outcome of hospital length of stay. A random effects meta-analysis was performed, and the results were reported as summary odds ratio (OR) and 95% confidence interval (CI). RESULTS: Twelve observational cohort studies published between 2001 and 2019 comprising 14 patient cohorts with a total of 95 856 patients were eligible for quantitative synthesis. Patients presenting on a weekend had a significantly higher risk of unadjusted in hospital mortality (OR 1.20, 95% CI 1.10 - 1.31, p < .001). Both the unadjusted 30 day mortality risk (OR 1.16, 95% CI 0.98 - 1.39, p = .090) and unadjusted 90 day mortality risk (OR 1.12, 95% CI 0.90 - 1.40, p = .30) were higher for those presenting at a weekend, but neither reached statistical significance. There was a significantly greater risk of combined unadjusted in hospital, 30 and 90 day mortality for those presenting at a weekend (OR 1.17, 95% CI 1.09 - 1.27, p < .001). Hospital length of stay was not statistically different between groups. CONCLUSION: There is an association between weekend admission and higher mortality in patients presenting with ruptured abdominal aortic aneurysm.

Caesarean section in pregnancies conceived by assisted reproductive technology: a systematic review and meta-analysis.

BACKGROUND: Caesarean section rates are higher among pregnancies conceived by assisted reproductive technology (ART) compared to spontaneous conceptions (SC), implying an increase in neonatal and maternal morbidity. We aimed to compare caesarean section rates in ART pregnancies versus SC, overall, by indication (elective versus emergent), and by type of ART treatment (in-vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), fresh embryo transfer, frozen embryo transfer) in a systematic review and meta-analysis. METHODS: We searched Medline, EMBASE and CINAHL databases using the OVID Platform from 1993 to 2019, and the search was completed in January 2020. The eligibility criteria were cohort studies with singleton conceptions after in-vitro fertilization and/or intracytoplasmic sperm injection using autologous oocytes versus spontaneous conceptions. The study quality was assessed using the Newcastle Ottawa Scale and GRADE approach. Meta-analyses were performed using odds ratios (OR) with a 95% confidence interval (CI) using random effect models in RevMan 5.3, and I-squared (I2) test > 75% was considered as high heterogeneity. RESULTS: One thousand seven hundred fifty studies were identified from the search of which 34 met the inclusion criteria. Compared to spontaneous conceptions, IVF/ICSI pregnancies were associated with a 1.90-fold increase of odds of caesarean section (95% CI 1.76, 2.06). When stratified by indication, IVF/ICSI pregnancies were associated with a 1.91-fold increase of odds of elective caesarean section (95% CI 1.37, 2.67) and 1.38-fold increase of odds of emergent caesarean section (95% CI 1.09, 1.75). The heterogeneity of the studies was high and the GRADE assessment moderate to low, which can be explained by the observational design of the included studies. CONCLUSIONS: The odds of delivering by caesarean section are greater for ART singleton pregnancies compared to spontaneous conceptions. Preconception and pregnancy care plans should focus on minimizing the risks that may lead to emergency caesarean sections and finding strategies to understand and decrease the rate of elective caesarean sections.

Decision to delivery interval and associated factors for emergency cesarean section: a cross-sectional study.

BACKGROUND: Emergency cesarean section is a commonly performed surgical procedure in pregnant women with life-threatening conditions of the mother and/or fetus. According to the Royal College of Obstetricians and Gynecologists and the American College of Obstetricians and Gynecologists, decision to delivery interval for emergency cesarean sections should be within 30 min. It is an indicator of quality of care in maternity service, and if prolonged, it constitutes a third-degree delay. This study aimed to assess the decision to delivery interval and associated factors for emergency cesarean section in Bahir Dar City Public Hospitals, Ethiopia. METHOD: An institution-based cross-sectional study was conducted at Bahir Dar City Public Hospitals from February to May 2020. Study participants were selected using a systematic random sampling technique. A combination of observations and interviews was used to collect the data. Data entry and analysis were performed using Epi-data version 3.1 and SPSS version 25, respectively. Statistical significance was set at p < 0.05. RESULT: Decision-to-delivery interval below 30 min was observed in 20.3% [95% CI = 15.90-24.70%] of emergency cesarean section. The results showed that referral status [AOR = 2.5, 95% CI = 1.26-5.00], time of day of emergency cesarean section [AOR = 2.5, 95%CI = 1.26-4.92], status of surgeons [AOR = 2.95, 95%CI = 1.30-6.70], type of anesthesia [AOR = 4, 95% CI = 1.60-10.00] and transfer time [AOR = 5.26, 95% CI = 2.65-10.46] were factors significantly associated with the decision to delivery interval. CONCLUSION: Decision-to-delivery intervals were not achieved within the recommended time interval. Therefore, to address institutional delays in emergency cesarean section, providers and facilities should be better prepared in advance and ready for rapid emergency action.

Emergency response to COVID-19 epidemic: One Chinese blood centre's experience.

OBJECTIVE: The COVID-19 epidemic has caused a significant global social and economic impact since December 2019. The objective of this study was to demonstrate the emergency response of a Chinese blood centre on maintaining both the safety and the sufficiency of blood supply during large, emerging, infectious epidemics. MATERIALS AND METHODS: Early on in the outbreak of COVID-19, the Chengdu Blood Center developed strategies and implemented a series of measures, including enhanced recruitment efforts, addition of new donation deferral criteria and notification after donation, optimisation of donor experience, development and implementation of a new coronavirus nucleic acid detection technology platform for blood screening and screening all donations for SARS-CoV-2 RNA to maximumly protect the safety of blood supply during a time of unclear risk. RESULTS: Starting on February 20, the immediate satisfaction rate of blood product orders in Chengdu city's clinical settings reached 100%, and there was no case of blood transfusion infection. CONCLUSION: The recent experience during the outbreak of SARS-CoV-2 reminded us that improvement in the areas of national and international collaborative programmes for dealing with blood availability and safety concerns during early stages of a disaster and regional and national mechanisms for timely communication with the general public on behalf of blood services should help to better prepare us for future disasters.

Controlled observational study and economic evaluation of the effect of city-centre night-time alcohol intoxication management services on the emergency care system compared with usual care.

BACKGROUND: Alcohol intoxication management services (AIMS) provide an alternative care pathway for alcohol-intoxicated adults otherwise requiring emergency department (ED) services and at times of high incidence. We estimate the effectiveness and cost-effectiveness of AIMS on ED attendance rates with ED and ambulance service performance indicators as secondary outcomes. METHODS: A controlled longitudinal retrospective observational study in English and Welsh towns, six with AIMS and six without. Control and intervention cities were matched by sociodemographic characteristics. The primary outcome was ED attendance rate per night, secondary analyses explored hospital admission rates and ambulance response times. Interrupted time series analyses compared control and matched intervention sites pre-AIMS and post-AIMS. Cost-effectiveness analyses compared the component costs of AIMS to usual care before with results presented from the National Health Service and social care prospective. The number of diversions away from ED required for a service to be cost neutral was determined. RESULTS: Analyses found considerable variation across sites, only one service was associated with a significant reduction in ED attendances (-4.89, p<0.01). The services offered by AIMS varied. On average AIMS had 7.57 (mean minimum=1.33, SD=1.37 to mean maximum=24.66, SD=12.58) in attendance per session, below the 11.02 diversions away from ED at which services would be expected to be cost neutral. CONCLUSIONS: AIMSs have variable effects on the emergency care system, reflecting variable structures and processes, but may be associated with modest reductions in the burden on ED and ambulance services. The more expensive model, supported by the ED, was the only configuration likely to divert patients away from ED. AIMS should be regarded as fledgling services that require further work to realise benefit. TRIAL REGISTRATION NUMBER: ISRCTN63096364.

Urgent Care Centers Delay Emergent Surgical Care Based on Patient Insurance Status in The United States.

OBJECTIVE: Patients may call urgent care centers (UCCs) with urgent surgical conditions but may not be properly referred to a higher level of care. This study aims to characterize how UCCs manage Medicaid and privately insured patients who present with an emergent condition. METHODS: Using a standardized script, we called 1245 randomly selected UCCs in 50 states on 2 occasions. Investigators posed as either a Medicaid or a privately-insured patient with symptoms of an incarcerated inguinal hernia. Rates of direct emergency department (ED) referral were compared between insurance types. RESULTS: A total of 1223 (98.2%) UCCs accepted private insurance and 981 (78.8%) accepted Medicaid. At the 971 (78.0%) UCCs that accepted both insurance types, direct-to-ED referral rates for private and Medicaid patients were 27.9% and 33.8%, respectively. Medicaid patients were significantly more likely than private patients to be referred to the ED [odds ratio (OR) 1.32, 95% confidence interval (CI) 1.09-1.60]. Private patients who were triaged by a clinician compared to nonclinician staff were over 6 times more likely to be referred to the ED (OR 6.46, 95% CI 4.63-9.01). Medicaid patients were nearly 9 times more likely to have an ED referral when triaged by a clinician (OR 8.72, 95% CI 6.19-12.29). CONCLUSIONS: Only one-third of UCCs across the United States referred an apparent emergent surgical case to the ED, potentially delaying care. Medicaid patients were more likely to be referred directly to the ED versus privately insured patients. All patients triaged by clinicians were significantly more likely to be referred to the ED; however, the disparity between private and Medicaid patients remained.

Using Artificial Intelligence to Predict Surgical Shunts in Men with Ischemic Priapism.

PURPOSE: Ischemic priapism is a urological emergency that requires prompt intervention to preserve erectile function. Characteristics that influence escalation to surgical intervention remain unclear. We identified factors and developed machine learning models to predict which men presenting with ischemic priapism will require shunting. MATERIALS AND METHODS: We identified men with ischemic priapism admitted to the emergency department of our large county hospital between January 2010 and June 2019. We collected patient demographics, etiology, duration of priapism prior to intervention, interventions attempted and escalation to shunting. Machine learning models were trained and tested using R to predict which patients require surgical shunting. RESULTS: A total of 334 encounters of ischemic priapism were identified. The majority resolved with intracavernosal phenylephrine injection and/or cavernous aspiration (78%). Shunting was required in 10% of men. Median duration of priapism before intervention was longer for men requiring shunting than for men who did not (48 vs 7 hours, p=0.030). Patients with sickle cell disease as the etiology were less likely to require shunting compared to all other etiologies (2.2% vs 15.2%, p=0.035). CONCLUSIONS: Men with longer duration of priapism before treatment more often underwent shunting. However, phenylephrine injection and aspiration remained effective for priapism lasting more than 36 hours. Having sickle cell disease as the etiology of priapism was protective against requiring shunting. We developed artificial intelligence models that performed with 87.2% accuracy and created an online probability calculator to determine which patients with ischemic priapism may require shunting.

Surgeons With Five or More Actual Cricothyrotomies Perform Significantly Better on a Virtual Reality Simulator.

BACKGROUND: Discriminating performance of learners with varying experience is essential to developing and validating a surgical simulator. For rare and emergent procedures such as cricothyrotomy (CCT), the criteria to establish such groups are unclear. This study is to investigate the impact of surgeons' actual CCT experience on their virtual reality simulator performance and to determine the minimum number of actual CCTs that significantly discriminates simulator scores. Our hypothesis is that surgeons who performed more actual CCT cases would perform better on a virtual reality CCT simulator. METHODS: 47 clinicians were recruited to participate in this study at the 2018 annual conference of the Society of American Gastrointestinal and Endoscopic Surgeons. We established groups based on three different experience thresholds, that is, the minimal number of CCT cases performed (1, 5, and 10), and compared simulator performance between these groups. RESULTS: Participants who had performed more clinical cases manifested higher mean scores in completing CCT simulation tasks, and those reporting at least 5 actual CCTs had significantly higher (P = 0.014) simulator scores than those who had performed fewer cases. Another interesting finding was that classifying participants based on experience level, that is, attendings, fellows, and residents, did not yield statistically significant differences in skills related to CCT. CONCLUSIONS: The simulator was sensitive to prior experience at a threshold of 5 actual CCTs performed.

Failure to Rescue in Emergency Surgery: Is Precedence a Problem?

BACKGROUND: Mortality in emergency general surgery (EGS) is often attributed to patient condition, which may obscure opportunities for improvement in care. Identifying failure to rescue (FTR), or death after complication, may reveal these opportunities. FTR has been problematic in trauma secondary to low precedence rates (proportion of deaths preceded by complication). We sought to evaluate this in EGS, hypothesizing that precedence is lower in EGS than in similar elective operations. METHODS: National Inpatient Sample data from January 2014 through September 2015 were used. 150,027 adult operative EGS complete cases were defined by emergent admission, one of seven International Classification of Diseases, ninth revision (ICD-9) procedure group codes for common EGS operations, and timing to operation (<48 h); these represent 750,135 patients under the National Inpatient Sample sampling design. Deaths were precedented if one of eight prespecified complications was identified. Chi-squared tests were used to compare precedence rates between selected emergent and elective operations. RESULTS: There was a 2.5% mortality rate in this cohort of operative EGS patients, with an 84.1% (95% CI: 82.7%-85.4%) precedence rate. Among the seven listed procedure groups, those with clinically reasonable elective analogs were cholecystectomy, colon resection, and laparotomy. Emergent versus elective precedence rates were 90.2% versus 82.0% (P = 0.004) for colon resection, 81.3% versus 86.8% (P = 0.26) for cholecystectomy, and 68.8% versus 92.7% (P < 0.001) for laparotomy. CONCLUSIONS: Precedence rates in EGS were higher than expected and were similar to previously published rates in nonemergent surgery, suggesting that FTR is likely to be reliable using standard methodology. Management of complications after emergency operation may represent significant opportunities to prevent mortality.

Perioperative Outcomes and Predictors of Mortality After Surgery for Sigmoid Volvulus.

BACKGROUND: Data on outcomes after surgery for sigmoid volvulus is limited. The aim of this study was to develop a model to predict need for emergent surgery and mortality after resection for sigmoid volvulus. METHODS: The NSQIP database was queried from 2012 to 2016 to identify patients undergoing segmental resection for sigmoid volvulus. Pre-, intra-, and post-operative variables were compared. Primary and secondary outcomes were emergent surgery and risk of mortality, respectively. Chi-square and Fischer's test for categorical variables and the Mann-Whitney test for continuous variables were used. Significant variables for each outcome were entered into a logistic regression model to predict the outcomes. RESULTS: 2086 patients met inclusion criteria. Factors associated with emergency surgery included female gender, relative hematocrit elevation, relative leukocytosis, acute kidney injury, preoperative sepsis, prior functional independence, and bleeding disorders. Laparoscopic resection and mechanical bowel preparation were more commonly used in the nonemergent setting. Patients having emergent resection were more likely to suffer from postoperative superficial surgical site infection, pneumonia, cardiac arrest, septic shock, myocardial infarction, and receive perioperative transfusion. No difference was seen in ileus, readmission or reoperation rates in the emergent and nonemergent groups. Factors predictive of postoperative mortality included increased age, systemic sepsis, and emergent surgery. Independence before illness, higher albumin levels, and lower BMI were shown to be protective. CONCLUSIONS: Emergent resection is independently associated with poor postoperative outcomes and mortality. Predictors of need for emergent resection and mortality identified in this study can be used to aid in shared decision-making for patients with sigmoid volvulus.

Defining the Burden of Emergency General Surgery in Transplant Patients: A Nationwide Examination.

BACKGROUND: Transplant patients are at the risk of serious sequelae from medical and surgical intervention. The incidence and burden of emergency general surgery (EGS) in transplant patients are scarcely known. This study aims to identify predictors of outcomes in transplant patients with EGS needs. METHODS: The Nationwide Inpatient Sample (2007-2011) was queried for adult patients (aged ≥16 y) who underwent abdominal visceral transplantation. These were further queried for a secondary diagnosis of an American Association for the Surgery of Trauma-defined EGS condition. Outcome measures included mortality, complications, length of stay, and cost of care. Propensity scores were used to match patients across baseline characteristics. Multivariate analysis was used to further adjust propensity score quintiles and hospital-level characteristics. RESULTS: A total of 35,573 transplant patients were identified. Of these, 30% (n = 10,676) developed an EGS condition. Most common EGS conditions were resuscitation (7.7%), intestinal obstruction (7.3%), biliary conditions (3.9%), and hernias (3.2%). Patients with public insurance, those in the highest income quartile, and those treated at larger hospitals had a lower likelihood of developing an EGS condition (P < 0.05). Patients with an EGS condition had a ninefold higher likelihood of mortality and a threefold higher likelihood of developing complications (odds ratio [95% confidence interval (CI)]: 9.21 [1.80-10.89] and 3.17 [3.02-3.34], respectively). Transplant patients after EGS had a longer risk-adjusted length of stay and cost of index hospitalization (Absolute difference [95% CI]: 12.70 [12.14-13.26] and $57,797 [55,415-60,179], respectively]). CONCLUSIONS: Transplant patients fare poorly after developing an EGS condition. The results of this study will help in identifying at-risk patients and determining outcomes.
