Abstract
BACKGROUND Motor vehicle collision (MVC) is a leading cause of accidental death in children. Despite effective forms of child safety restraint (eg, car seat and booster seat), studies demonstrate poor compliance with guidelines. The goal of this study was to delineate injury patterns, imaging usage, and potential demographic disparities associated with child restraint use following MVC. METHODS A retrospective review of the North Carolina Trauma Registry was performed to determine demographic factors and outcomes associated with improper restraint of children (0-8 years) involved in MVC from 2013 to 2018. Bivariate analysis was performed by the appropriateness of restraint. Multivariable Poisson regression identified demographic factors for the relative risk of inappropriate restraint. RESULTS Inappropriately restrained patients were older (5.1 years v. 3.6 yrs, P < .001) and weighed more (44.1 lbs v. 35.3 lbs, P < .001). A higher proportion of African American (56.9% v. 39.3%, P < .001) and Medicaid (52.2% v. 39.0%, P < .001) patients were inappropriately restrained. Multivariable Poisson regression showed that African American patients (RR 1.43), Asian patients (RR 1.51), and Medicaid payor status (RR 1.25) were associated with a higher risk of inappropriate restraint. Inappropriately restrained patients had a longer length of stay, but injury severity score and mortality were no different. DISCUSSION African American children, Asian children, and Medicaid insurance payor status patients had an increased risk of inappropriate restraint use in MVC. This study describes unequal restraint patterns in children, which suggests opportunity for targeted patient education and necessitates research to further delineate the underlying etiology of these differences.

Abstract
Background: Both general surgeons (GS) and pediatric surgeons (PS) perform a high volume of appendectomies in pediatric patients, but there is a paucity of data on these outcomes based on surgeon training. We performed a systematic review and meta-analysis to compare postoperative outcomes and perioperative resource utilization for pediatric appendectomies.Methods: We searched PubMed to identify articles examining the association between surgeon specialization and outcomes for pediatric patients undergoing appendectomies. Study selection, data extraction, risk of bias assessment, and quality assessment were performed by one reviewer, with another reviewer to resolve discrepancies.Results: We identified 4799 articles, with 98.4% (4724/2799) concordance after initial review. Following resolution of discrepancies, 16 studies met inclusion criteria. Of the studies that reported each outcome, GS and PS demonstrated similar rates of readmission within 30 days (pooled RR 1.61 95% CI 0.66, 2.55) wound infections (pooled RR 1.07, 95% CI .55, 1.60), use of laparoscopic surgery (pooled RR 1.87, 95% CI .21, 3.53), postoperative complications (pooled RR 1.40, 95% CI .83, 1.97), use of preoperative imaging (pooled RR .98,95% CI .90, 1.05), and intra-abdominal abscesses (pooled RR .80, 95% CI .03, 1.58). Patients treated by GS did have a significantly higher risk of negative appendectomies (pooled RR 1.47, 95% CI 1.10, 1.84) when compared to PS.Discussion: This is the first meta-analysis to compare outcomes for pediatric appendectomies performed by GS compared to PS. Patient outcomes and resource utilization were similar among PS and GS, except for negative appendectomies were significantly more likely with GS.

Abstract
INTRODUCTION Enhanced recovery protocols (ERP) have been associated with fewer postoperative complications in adult colorectal surgery patients, but there is a paucity of data on pediatric patients. Our aim is to describe the effect of an ERP, compared to conventional care, on pediatric colorectal surgical complications. MATERIALS AND METHODS We performed a single institution, retrospective cohort study (2014-2020) on pediatric (≤18 years old) colorectal surgery patients pre- and post-implementation of an ERP. Bivariate analysis and logistic regression were used to assess the effect of an ERP on return visits to the emergency room, reoperation, and readmission within 30-days. RESULTS There were 194 patients included in this study, with 54 in the control cohort and 140 in the ERP cohort. There was no significant difference in the age, BMI, primary diagnosis, or use of laparoscopic technique between the cohorts. The ERP cohort had a significantly shorter foley duration, postoperative stay, and had nerve blocks performed. After controlling for pertinent covariates, the ERP cohort experienced higher odds of reoperation within 30 days (OR 5.83, P = .04). There was no significant difference in the other outcomes analyzed. CONCLUSION In this study, there was no difference in the odds of overall complications, readmission or return to the ER within 30-days of surgery. However, although infrequent, there were higher odds of returns to the OR within 30 days. Future studies are needed to analyze how adherence to individual components may influence patient outcomes to ensure patient safety during ERP implementation.

Abstract
INTRODUCTION The delivery of pediatric surgical care for gallbladder (GB) and biliary disease involves both General Surgeons (GS) and Pediatric Surgeons (PS). There is a lack of data describing how surgeon specialty impacts practice patterns and healthcare charges. METHODS We performed a retrospective review of the North Carolina Inpatient Hospital Discharge Database (2013-2017) on pediatric patients (≤18 years) undergoing surgery for biliary pathology. We performed multivariate linear regression comparing surgeons with surgical charge. RESULTS 12,531 patients had GB or biliary pathology and 4023 (32.1%) had cholecystectomies. The most common procedure for PS and GS was cholecystectomy for cholecystitis (n = 509, 54.0% and n = 2275, 76.4%, p < 0.001), respectively. The hospital ($26,605, IQR $18,955-37,249, vs. $17,451, IQR $13,246-23,478, p < 0.001) and surgical charges ($15,465, IQR $12,233-22,203, vs. $10,338, IQR $6837-14,952, p < 0.001) were higher for PS than GS. Controlling for pertinent variables, surgical charges for PS were $4192 higher than for GS (95% CI: $2162-6122). CONCLUSION The cholecystectomy charge differential between PS and GS is significant and persisted after controlling for pertinent covariates.

Abstract
INTRODUCTION The delivery of pediatric surgical care for acute appendicitis involves general surgeons (GS) and pediatric surgeons (PS), but the differences in clinical practice are primarily undescribed. We examined charge differences between GS and PS for the treatment of pediatric acute appendicitis. METHODS We performed a retrospective review of the North Carolina hospital discharge database (2013-2017) in pediatric patients (≤18 y) who had surgery for appendiceal pathology (acute or chronic appendicitis and other appendiceal pathology). We performed a bivariate analysis of surgical charges over the type of surgical providers (GS, PS, other specialty, and unassigned surgeons). RESULTS Over the study period, 21,049 patients had appendicitis or other diseases of the appendix, and 15,230 (72.4%) underwent appendectomy. Patients who were operated on by PS were younger (10 y, interquartile range (IQR): 6-13 versus 13 y, IQR: 9-16, P < 0.001). Acute appendicitis was diagnosed in 2860 (44.3%) and 3173 (49.2%) of the PS and GS cohorts, respectively, P = 0.008. PS compared to GS performed a higher percentage of laparoscopic (n = 2,697, 89.4% versus n = 2,178, 65.5%) than open appendectomies (n = 280, 9.3% versus n = 1,118, 33.6%), P < 0.001. The overall hospital charges were $28,081 (IQR: $21,706-$37,431) and $24,322 (IQR: $17,906-$32,226) for PS and GS, respectively, P < 0.001. Surgical charges where higher for PS than GS, $12,566 (IQR: $9802-$17,462) and $8051 (IQR: $5872-$2331), respectively. When controlling for diagnosis, surgical approach, emergent status, age, and surgical cost of appendiceal surgery, and hospital charges following appendiceal surgery were $4280 higher for PS than GS (95% CI: 3874-4687). CONCLUSIONS The total charge for operations for appendiceal disease is significantly higher for PS compared to GS. Pediatric surgeons had increased surgical charges compared to GS but decreased radiology charges. The specific reasons for these differences are not clearly delineated in this data set and persist after controlling for relevant covariates. However, these data demonstrate that increasing value in pediatric appendicitis may require specialty-based targets.

Abstract
INTRODUCTION Blood loss is a hallmark of traumatic injury. Massive transfusion, historically defined as the replacement by transfusion of 10 units of packed red blood cells (PRBCs) in 4 h, is a response to uncontrolled hemorrhage. We sought to identify blood transfusion thresholds in which predicted mortality exceeds 50%. METHODS We analyzed the 2017-2019 National Trauma Database. Inclusion criteria included patients ≥18 y who received ≥1 unit of PRBCs. Statistical analysis included bivariate analysis, logistic regression for mortality, and adjusted predicted probability modeling was utilized. RESULTS We identified 61,676 patients for analysis. The 50% predicted mortality for all patients was 31 PRBC units. The 50% predicted mortality was 6 units of PRBCs for elderly trauma patients 80 y and older. CONCLUSIONS Blood remains as scarce resource in hospitals especially with trauma. Patients receiving a massive transfusion over a short period of time may exhaust blood bank supply with diminishing survival benefit. Surgeons should be judicious regarding continued blood usage once the 50% predicted mortality threshold is reached.

Abstract
Patients experience delays in emergency surgical care. Our 3-month mixed-methods observational prospective study examined the duration of in-hospital delays (IHDs) to emergency surgery at a tertiary hospital in Malawi and perceived reasons for such delay, assessing the correlation between surgery and anesthesia. Delays over two hours occurred in the majority, and almost 20% waited over twelve hours. However, we found no correlation between surgeons and anaesthetists in the perceived reasons for In-hospital delays to emergency surgical care.

Abstract
BACKGROUND Trauma scoring systems can identify patients who should be transferred to referral hospitals, but their utility in LMICs is often limited. The Malawi Trauma Score (MTS) reliably predicts mortality at referral hospitals but has not been studied at district hospitals. We sought to validate the MTS at a Malawi district hospital and evaluate whether MTS is predictive of transfer to a referral hospital. METHODS We performed a retrospective study using trauma registry data from Salima District Hospital (SDH) from 2017 to 2021. We excluded patients brought in dead, discharged from the Casualty Department, or missing data needed to calculate MTS. We used logistic regression modeling to study the relationship between MTS and mortality at SDH and between MTS and transfer to a referral hospital. We used receiver operating characteristic analysis to validate the MTS as a predictor of mortality. RESULTS We included 2196 patients (84.3% discharged, 12.7% transferred, 3.0% died). These groups had similar ages, sex, and admission vitals. Mean (SD) MTS was 7.9(3.0) among discharged patients, 8.4(3.9) among transferred patients, and 14.2(8.0) among patients who died (p < 0.001). Higher MTS was associated with increased odds of mortality at SDH (OR 1.21, 95% CI 1.14-1.29, p < 0.001) but was not related to transfer. ROC area for mortality was 0.73 (95% CI 0.65-0.80). CONCLUSIONS MTS is predictive of district hospital mortality but not inter-facility transfer. We suggest that MTS be used to identify patients with severe trauma who are most likely to benefit from transfer to a referral hospital.

Abstract
BACKGROUND Gastrostomy tube (GT) placement is a common procedure in infants (≤1-year-old). There is variation in patient selection and a paucity of studies examining which patients require long term enteral access. The objective of this study was to assess demographic and clinical factors associated with persistent GT use (PGU) at 1-year after placement. METHODS We performed a single-institution retrospective review of patients ≤1-year-old who underwent GT placement from January 31, 2014, and January 31, 2020, using institutional NSQIP-P data supplemented with chart review. Multivariable logistic regression analysis was performed to identify factors associated with PGU. Clinical predictors were selected a priori, and a p-value less than 0.05 was used to detect a significant association. RESULTS 140 patients were included, and 118 had a 1-year follow-up. At 1-year following GT placement, 38 patients had weaned from their GT (32.2%). Failure to thrive (FTT), and inpatient admission prior to surgery are associated with increased odds of PGU at 1-year after surgery, OR: 5.19 and 6.02, respectively. There is an inverse association between the percentage of feeds taken by mouth at the time of surgery and the odds of PGU at 1-year (OR: 0.03). CONCLUSION Patients who have FTT (documented prior to surgery) or an inpatient admission prior to GT had a higher odds of PGU at 1-year post-op. Additionally, the amount taken by mouth at the time of GT placement was inversely related to PGU. These factors are important in determining the need for a surgical gastrostomy tube.

Abstract
INTRODUCTION Drowning is a public health problem that is under-reported in Africa. We sought to evaluate the epidemiology and risk factors for drownings in Malawi. METHODS We performed a retrospective review of all pediatric (≤15 years old) patients who presented following a drowning incident to Kamuzu Central Hospital in Lilongwe, Malawi, from 2009-19. Demographics and outcomes were compared between survivors and non-survivors. Logistic multivariate regression analysis was used to identify factors associated with increased odds of mortality. RESULTS There were 156 pediatric drowning victims during the study period. The median age at presentation was 3 (IQR: 2-7 years). Survivors were younger [median age: 2 years (IQR: 2-5) vs. 5 years (IQR: 2-10), p = 0.004], with a higher proportion of drownings occurring at home (85.6% vs. 58.3%, p = 0.001) compared to non-survivors. Patients who had a drowning event at a public space had increased odds of mortality (OR 8.17, 95% CI 2.34-28.6). Patients who were transferred (OR 0.03, 95% CI 0.003-0.25) and had other injuries (OR 0.20, 95% CI 0.06-0.70) had decreased odds of mortality following drowning. CONCLUSION Over half of pediatric drowning victims at a tertiary-care facility in Malawi survived. Drowning survivors were significantly younger, more likely to have drowned at home, and transported by private vehicles and minibus than non-survivors. There is a need for scalable, cost-effective drowning prevention strategies that focus on water safety education and training community members and police officers in basic life support and resuscitation.

Abstract
PURPOSE Burn outcome data in infants is lacking from sub-Saharan Africa. We, therefore, sought to assess the characteristics and predictors of in-hospital burn mortality in a resource-limited setting. METHODS We performed a retrospective study of the prospectively collected Burn Injury Surveillance database from June 2011 to December 2019. We performed bivariate analysis and Poisson regression to assess risk factors for mortality in our infant burn population. RESULTS 115 (7.3%) infants met inclusion criteria. The median age of 8 months (IQR: 6-10) and primarily male (n = 67, 58.8%). Most burns were from scald (n = 62, 53.9%). Infant burn mortality was 12.2%. Poisson multivariable regression to determine burn mortality risk in infants showed that increased %TBSA burns (RR 1.04, 95% CI 1.01-1.07) and flame burns (RR 3.08, 95%CI 1.16-8.16) had a higher risk of mortality. Having surgery reduced the relative risk of death for infants with burns. CONCLUSION We show that factors that increase infant burn mortality risk include percent total body surface area burn, flame burn mechanism, and lack of operative intervention. Increasing burn operative capability, particularly for infants and other children, is imperative.

Abstract
Purpose of Review As the United States’ population diversifies, urgent action is required to identify, dismantle, and eradicate persistent health disparities. The surgical community must recognize how patients’ values, beliefs, and behaviors are influenced by race, ethnicity, nationality, language, gender, socioeconomic status, physical and mental ability, sexual orientation, and occupation. Recent Findings Lately, health disparities have been highlighted during the COVID-19 pandemic. Surgery is no exception, with notable disparities occurring in pediatric, vascular, trauma, and cardiac surgery. In response, numerous curricula and training programs are being designed to increase cultural competence and safety among surgeons. Summary Cultural competence, safety, humility, and dexterity are required to improve healthcare experiences and outcomes for minorities. Various opportunities exist to enhance cultural competency and can be implemented at the medical student, resident, attending, management, and leadership levels.

Abstract
INTRODUCTION Trauma is a leading cause of morbidity and mortality worldwide, and patients in low- and middle-income countries are disproportionately affected. Organized trauma systems, including appropriate transfer to a higher level of care, improve trauma outcomes. We sought to evaluate the relationship between transfer status and trauma mortality in Malawi. METHODS We performed a retrospective analysis of trauma patients admitted to Kamuzu Central Hospital (KCH), a trauma center in Lilongwe, Malawi, between January 1, 2013, and May 30, 2018. Transfer status was categorized as direct if a patient arrives at KCH from the injury scene and indirect if a patient comes to KCH from another health care facility. We used logistic regression modeling to evaluate the relationship between transfer status and in-hospital mortality. RESULTS A total of 8369 patients were included in the study. The mean age was 34.6 years (SD 15.8), and 81% of patients were male. The most common mechanism of injury was motor vehicle collision. Injury severity did not significantly differ between the two groups. Crude mortality was 4.8% for indirect and 2.6% for direct transfers. After adjusting for relevant covariates, odds ratio of mortality was 2.12 (1.49-3.02, p < 0.001) for indirect versus direct transfers. CONCLUSION Trauma patients indirectly transferred to a trauma center have nearly double the risk of mortality compared to direct transfers. Trauma outcome improvement efforts must focus on strengthening prehospital care, improving district hospital capacity, and developing protocols for early assessment, treatment, and transfer of trauma patients to a trauma center.

DESIGN Retrospective cohort study SETTING: Health records of 12 Midwest hospitals and 60 clinics in Minnesota between March 4, 2020, and August 19, 2020 PATIENTS: Polymerase chain reaction-positive COVID-19 patients EXPOSURES: Area Deprivation Index (ADI) and primary language MAIN MEASURES: The primary outcome was COVID-19 severity, using hospitalization within 45 days of diagnosis as a marker of severity. Logistic and competing-risk regression models assessed the effects of neighborhood-level deprivation (using the ADI) and primary language. Within race, effects of ADI and primary language were measured using logistic regression. RESULTS A total of 5577 individuals infected with SARS-CoV-2 were included; 866 (n = 15.5%) were hospitalized within 45 days of diagnosis. Hospitalized patients were older (60.9 vs. 40.4 years, p < 0.001) and more likely to be male (n = 425 [49.1%] vs. 2049 [43.5%], p = 0.002). Of those requiring hospitalization, 43.9% (n = 381), 19.9% (n = 172), 18.6% (n = 161), and 11.8% (n = 102) were White, Black, Asian, and Hispanic, respectively. Independent of ADI, minority race/ethnicity was associated with COVID-19 severity: Hispanic patients (OR 3.8, 95% CI 2.72-5.30), Asians (OR 2.39, 95% CI 1.74-3.29), and Blacks (OR 1.50, 95% CI 1.15-1.94). ADI was not associated with hospitalization. Non-English-speaking (OR 1.91, 95% CI 1.51-2.43) significantly increased odds of hospital admission across and within minority groups. CONCLUSIONS Minority populations have increased odds of severe COVID-19 independent of neighborhood deprivation, a commonly suspected driver of disparate outcomes. Non-English-speaking accounts for differences across and within minority populations. These results support the ongoing need to determine the mechanisms that contribute to disparities during COVID-19 while also highlighting the underappreciated role primary language plays in COVID-19 severity among minority groups.

Abstract
BACKGROUND Trauma patients undergo routine contrast administration for diagnostic and therapeutic purposes. The aim of this study is to investigate the incidence and predictors of contrast-induced nephropathy requiring acute hemodialysis in the trauma population. METHODS Adult patients (age ≥16) were identified from the National Trauma Databank (2017-2018) and were grouped based on contrast received. The defined groups included no contrast, computed tomography intravascular contrast only, and angiography contrast. Patient demographic and clinical variables collected included vital signs (systolic blood pressure, pulse rate) recorded upon arrival to the emergency room, injury severity score, shock index, Glasgow Coma Scale, and mechanism. Outcome measures included mortality, hospital discharge disposition, intensive care unit and hospital length of stay, and need for hemodialysis. We performed a Poisson regression to assess relative risk for undergoing hemodialysis during hospital admission. RESULTS In total, 1,850,460 patients were included in the analysis (no contrast: 1,189,209; computed tomography intravascular contrast only: 621,846; angiography: 39,405); 3,135 patients required hemodialysis during the admission. Patients with reduced Glasgow Coma Scale, higher injury severity score, higher shock index, and preexisting diabetes mellitus and hypertension were more likely to require hemodialysis. Poisson regression revealed the relative risk of requiring hemodialysis as 1.49 with computed tomography intravascular contrast only, 4.33 with angiography only, and 5.35 with consecutive computed tomography intravascular and angiography. CONCLUSION Intravascular contrast administration through computed tomography and or angiography is independently associated with increased risk of requiring hemodialysis after a traumatic injury. Trauma surgeons should consider the necessity of contrast for each clinical situation and understand the potential for contrast-induced nephropathy.

Abstract
BACKGROUND Enhanced recovery protocols (ERP) are a multimodal approach to standardize perioperative care. To substantiate the benefit of a pediatric-centered pathway, we compared outcomes of children treated with pediatric ERP (pERP) versus adult (aERP) pathways. We aimed to compare components of each pathway to create a new comprehensive pERP to reduce variation in care. METHODS Retrospective study of children (≤18 y) undergoing elective colorectal surgery from August 2015 to April 2019 at a single institution managed with pERP versus aERP. Multivariable linear and logistic regression, adjusting for demographics and operation characteristics, were used to compare outcomes. RESULTS Out of 100 hospitalizations (72 patients) were identified, including 37 treated with pERP. pERP patients were, on average, younger (13 versus 16 y), more likely to be ASA III (70% versus 30%), and more likely to receive regional (32% versus 3%) or neuraxial (35% versus 8%) anesthesia. Epidural use was an independent risk factor for longer length of stay (P = 0.000). After adjustment, pERP patients had similar LOS and time to oral intake, but shorter foley duration. pERP patients used significantly fewer opioids and were less likely to return to the operating room within 30 d. 30-d readmissions and ED visits were also lower, but this was not statistically significant. CONCLUSIONS At our institution, data from both ERPs contributed formation of a synthesized pathway and reflected the pERP approach to opioid utilization and the aERP approach to earlier enteral nutrition.

Abstract
PURPOSE Inguinal hernias are one of the most common surgical conditions worldwide. Due to limited surgical access in low- and middle-income countries, many hernias present emergently; however, data on the resultant outcome disparities is limited. We, therefore, sought to describe the epidemiology, clinical features, and outcomes of incarcerated inguinal hernias at a tertiary center in Malawi. METHODS This is a retrospective analysis of the acute care surgery registry at Kamuzu Central Hospital in Lilongwe, Malawi. All patients > 13 years admitted with a non-reducible inguinal hernia from 2013 to 2019 were included. The primary outcome was in-hospital mortality. A Poisson multivariable regression determined factors associated with increased risk of mortality. RESULTS A total of 297 patients presented with non-reducible inguinal hernias, the majority of which were young (median age 38), male (93.6%), farmers (47.8%). Of the 81% who underwent surgery, 55% were delayed ≥ 24 h. 19.5% of hernias were strangulated. Overall mortality was 5.4%. Increased age (RR 1.06, 95% CI 1.01-1.12), shock index ≥ 1 (RR 4.82, 95% CI 1.45-16.09), and delay ≥ 24 h from presentation to operative intervention (RR 11.24, 95% CI 1.55-81.34) resulted in an increase in relative risk of mortality. CONCLUSION Non-reducible inguinal hernias largely affect young male farmers in Malawi. Delays to care can limit economic productivity for this rural population, as well as, yield considerable risk of mortality. While specific patient and institutional factors must be further elucidated, increased awareness, public health prioritization, and surgical capacity building is needed to reduce further hernia-related morbidity and mortality.

Abstract
INTRODUCTION Despite the ubiquity of motorized vehicular transport, non-motorized transportation continues to be common in sub-Saharan Africa. METHODS We performed a retrospective analysis of trauma patients presenting to Kamuzu Central Hospital in Malawi from February 2008 to May 2018. Demographic and clinical variables including injury characteristics and outcomes were collected. We performed bivariate and multivariate logistic regression to determine predictors of mortality following non-motorized vehicular trauma. RESULTS This study included 36,412 patients involved in vehicular road injuries. Patients in the non-motorized group had a preponderance of men (84% versus 73%, p<0.01). The proportion of patients with Glasgow Coma Scale > 8 was slightly higher in the non-motorized group (99% versus 98%, p<0.01), though injury severity did not differ significantly between the two groups. A higher proportion in the motorized group had the most severe injury of contusions and abrasions (56% versus 50%, p<0.01). In contrast, the non-motorized group had a higher proportion of orthopedic injuries (24% versus 16%, p<0.01). The crude mortality rate was 4.51% and 2.15% in the motorized and non-motorized groups, respectively. After controlling for demographic factors and injury severity, the incidence rate ratio of mortality did not differ significantly between motorized and non-motorized trauma groups (IRR 0.91, p=0.35). CONCLUSIONS Non-motorized vehicular trauma remains a significant proportion of morbidity and mortality resulting from road traffic injuries. The injury severity and incidence rate ratio of mortality did not differ between motorized and non-motorized trauma groups. Health care providers should not underestimate the severity of injuries from non-motorized trauma.

Abstract
INTRODUCTION The relationship between increasing surgical demand and access to operative intervention remains unclear in delivering general surgical care in resource-limited settings, where demand often exceeds capacity. We sought to characterize the association between general surgery patient volume and operative intervention at a tertiary hospital in Malawi, which has an adequate surgical workforce. METHODS We analyzed patients admitted to Kamuzu Central Hospital Lilongwe, Malawi, with a general surgery complaint from 2018-2020. We examined the relationship between the census at the time of admission, the use of operative intervention, and the time to operative intervention. The patient census was defined as low (≤30 patients), medium (31-49 patients), and high (≥50 patients), based on historical patterns. RESULTS 2,701 patients were included. The mean daily census was 46 patients (SD 10). For the medium and high census, the adjusted risk ratio of undergoing surgery was 0.86 (95% CI 0.78, 0.95) and 0.81 (95% CI 0.73, 0.90), respectively, adjusted for admission diagnosis. For patients requiring urgent abdominal exploration, at a census of 25, the adjusted mean time to operation was 0.8 days (95% CI 0.1, 1.5) compared to 2.8 days (95% CI 2.1, 3.5) at a census of 65 patients. CONCLUSIONS Despite an adequate surgical workforce, an increasing mean daily census significantly reduced the use of operative intervention and increased time to operation for patients who needed urgent abdominal exploration. Additional improvements in the surgical ecosystem beyond surgeons are necessary to improve surgical access.
