ICU Readmission in Injured Older Adults: Modifiable Risk Factors and Implications.

BACKGROUND: Prior evaluations of ICU readmission among injured older adults have inconsistently identified risk factors, with findings limited by use of sub-analyses and small sample sizes. This study aimed to identify risk factors for and implications of ICU readmission in injured older adults. METHODS: This retrospective, single-center cohort study was conducted at a High-Volume Level 1 Trauma Center and included injured older adult patients (>65 years old) requiring at least one ICU admission during hospitalization between 2013-2018. Patients who died <48 hours of admission were excluded. Exposures included patient demographics and clinical factors. The primary outcome was ICU readmission. Multi-variable regression was used to identify risk factors for ICU readmission. RESULTS: 6,691 injured adult trauma patients were admitted from 2013-2018, 55.4% (n = 3,709) of whom were admitted to the ICU after excluding early deaths. Of this cohort, 9.1% (n = 339) were readmitted to the ICU during hospitalization. Readmitted ICU patients had a higher median Injury Severity Score (21 (IQR: 14-26) vs 16 (IQR: 10-24)), with similar mechanisms of injury between the two groups. Readmitted ICU patients had a significantly higher mortality (19.5%) compared to single ICU admission patients (9.9%) (p < 0.001) and higher rates of developing any complication, including delirium (61% vs 30%, p < 0.001). On multivariable analysis, the factors associated with the highest risk of readmission were delirium (RR = 2.6, 95% CI 2.07 - 3.26) and aspiration (RR = 3.04, 95% CI 1.67- 5.54). More patients in the single ICU admission cohort received comfort-focused care at the time of their death as compared to the ICU readmission cohort (93% vs 85%, p = 0.035). CONCLUSIONS: Readmission to the ICU is strongly associated with higher mortality for injured older adults. Efforts targeted at preventing respiratory complications and delirium in the geriatric trauma population may decrease the rates of ICU readmission and related mortality risk. LEVEL OF EVIDENCE: III/Epidemiologic.

Academic global surgical competencies: A modified Delphi consensus study.

Academic global surgery is a rapidly growing field that aims to improve access to safe surgical care worldwide. However, no universally accepted competencies exist to inform this developing field. A consensus-based approach, with input from a diverse group of experts, is needed to identify essential competencies that will lead to standardization in this field. A task force was set up using snowball sampling to recruit a broad group of content and context experts in global surgical and perioperative care. A draft set of competencies was revised through the modified Delphi process with two rounds of anonymous input. A threshold of 80% consensus was used to determine whether a competency or sub-competency learning objective was relevant to the skillset needed within academic global surgery and perioperative care. A diverse task force recruited experts from 22 countries to participate in both rounds of the Delphi process. Of the n = 59 respondents completing both rounds of iterative polling, 63% were from low- or middle-income countries. After two rounds of anonymous feedback, participants reached consensus on nine core competencies and 31 sub-competency objectives. The greatest consensus pertained to competency in ethics and professionalism in global surgery (100%) with emphasis on justice, equity, and decolonization across multiple competencies. This Delphi process, with input from experts worldwide, identified nine competencies which can be used to develop standardized academic global surgery and perioperative care curricula worldwide. Further work needs to be done to validate these competencies and establish assessments to ensure that they are taught effectively.

Defining the Culture of Surgery.

BACKGROUND: Surgical culture is often referenced but not well defined. Recent research and changing policies in graduate medical education have influenced the training paradigm and expectations of surgical trainees. It is unclear how these changes impact surgeons' understanding of surgical culture today and how those views impact surgical training. We sought to understand surgical culture and its impact on training from the perspective of a diverse group of surgeons with varied amounts of experience. STUDY DESIGN: A series of semi-structured, qualitative interviews were conducted with 21 surgeons and trainees in a single academic institution. Interviews were transcribed, coded, and analyzed using directed content analysis. RESULTS: We identified 7 major themes that impact surgical culture. Cohorts were separated by those who had been promoted to at least associate professor (late-career surgeons) and assistant professors, fellows, residents, and students (early-career surgeons). Both cohorts similarly emphasized patient-centered care, hierarchy, high standards, and meaningful work. Late- and early-career surgeons highlighted themes differently: late-career surgeons' perceptions were informed by experience and focused on challenges, complications, humility, and work ethic, while perceptions of early-career surgeons were more individually focused and referenced being goal-oriented and self-sacrificing, and focus on education and work-life balance. CONCLUSIONS: Late- and early-career surgeons both emphasize that patient-centered care is core to surgical culture. Early-career surgeons expressed more themes related to personal well-being, while late-career surgeons emphasized themes related to professional accomplishment. Differences in the perceived culture can lead to strained interactions between generations of surgeons and trainees, and a better understanding of these differences would lead to improved communication and interactions between these groups, as well as better management of expectations for surgeons in their training and career.

Perceptions of Gender Disparities in Access to Surgical Care in Malawi: A Community Based Survey.

BACKGROUND: Gender disparities in surgical care exist but have been minimally studied, particularly in low- and middle-income countries. This study explored perceptions and gender differences in health-seeking behavior and attitudes toward surgical care in Malawi among community members. METHODS: A survey tool was administered to adults ≥18 years old at a central hospital, district hospital, and two marketplaces in Malawi from June 2018 to December 2018. Responses from men and women were compared using chi-squared tests. RESULTS: Four hundred eighty-five adults participated in the survey, 244 (50.3%) men and 241 (49.7%) women. Women were more likely to state that fear of surgery might prevent them from seeking surgical care (29.1% of men, 43.6% of women, P = .0009). Both genders reported long wait times, medicine/physician shortages, and lack of information about when surgery is needed as potential barriers to seeking surgical care. More men stated that medical preference should be given to sons (17.1% of men, 9.3% of women, P = .01). Men were more likely to report that men should have the final word about household decisions (28.7% of men vs 19.5% of women, P < .0001) and were more likely to spend money independently (68.7% of married men, 37.5% of married women, P < .0001). Few participants reported believing gender equality had been achieved (61% of men and 66.8% of women). CONCLUSIONS: A multi-pronged approach is needed to reduce gender disparities in surgical care in Malawi, including addressing paternalistic societal norms, education, and improving health infrastructure.

The Impact of Vaping on Primary Spontaneous Pneumothorax Outcomes.

INTRODUCTION: Cigarette smoking is associated with primary spontaneous pneumothorax (PSP). Electronic cigarettes (E-cigarettes) are touted as a healthier alternative to cigarettes; however, the impact E-cigarette use has on PSP management is not known. The goal of this study was to determine if E-cigarette use is associated with inferior outcomes after PSP, compared to never smokers and cigarette smokers. METHODS: We conducted a retrospective cohort study of patients in a large tertiary care hospital system in an urban area who presented with PSP from September 2015 through February 2019. Primary spontaneous pneumothorax patients were identified from the institutional Society of Thoracic Surgeon (STS) database. Patients with pneumothoraces from traumatic, iatrogenic, and secondary etiologies were excluded. Baseline clinical and demographic data and outcomes including intervention(s) required, length of stay, and recurrence were evaluated. RESULTS: Identified were 71 patients with PSP. Seventeen (24%) had unverifiable smoking history. Of the remaining, 7 (13%) currently vaped, 27(50%) currently smoked cigarettes, and 20(37%) were never smokers. Mean age was 33 years; 80% male. All vapers required tube thoracostomy vs 74% of current smokers and 75% of never smokers. Vaping was associated with increased odds of recurrence compared to never smokers (OR 2.00, 95% CI 0.35,11.44). Vapers had the shortest median time to recurrence after initial hospitalization (10 d[4,18] v 20 d[5,13] cigarette smokers v 27 d[13 275] never smokers, P < .001). CONCLUSION: Vaping may complicate PSP outcomes. As vaping use increases, especially among adolescents, it is imperative that the manner of tobacco use is documented and considered when caring for patients, especially those with pulmonary problems.

Vaccination after spleen embolization: A practice management guideline from the Eastern Association for the Surgery of Trauma.

BACKGROUND: Angioembolization is an important adjunct in the non-operative management of adult trauma patients with splenic injury. Multiple studies have shown that angioembolization may increase the non-operative splenic salvage rate for patients with high-grade splenic injuries. We performed a systematic review and developed evidence-based recommendations regarding the need for post-splenectomy vaccinations after splenic embolization in trauma patients. METHODS: A systematic review and meta-analysis of currently available evidence were performed utilizing the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. RESULTS: Nine studies were identified and analyzed. A total of 240 embolization patients were compared to 443 control patients who neither underwent splenectomy nor were embolized. There was no statistical difference between the splenic immune function of embolized and control patients. In addition, a total of 3974 splenectomy patients was compared with 686 embolization patients. Embolization patients had fewer infectious complications and a greater degree of preserved splenic immune function. CONCLUSION: In adult trauma patients who have undergone splenic angioembolization, we conditionally recommend against routine post-splenectomy vaccinations. STUDY TYPE: systematic review/meta-analysis Level of evidence: level III.

Environmental impact of telehealth use for pediatric surgery.

BACKGROUND: The healthcare sector is responsible for 10% of US greenhouse gas emissions. Telehealth use may decrease healthcare's carbon footprint. Our institution introduced telehealth to support SARS-CoV-2 social distancing. We aimed to evaluate the environmental impact of telehealth rollout. METHODS: We conducted a retrospective cohort study of pediatric patients seen by a surgical or pre anesthesia provider between March 1, 2020 and March 1, 2021. We measured patient-miles saved and CO2 emissions prevented to quantify the environmental impact of telehealth. Miles saved were calculated by geodesic distance between patient home address and our institution. Emissions prevented were calculated assuming 25 miles per gallon fuel efficiency and 19.4 pounds of CO2 produced per gallon of gasoline consumed. Unadjusted Poisson regression was used to assess relationships between patient demographics, geography, and telehealth use. RESULTS: 60,773 in-person and 10,626 telehealth encounters were included. This represented an 8,755% increase in telehealth use compared to the year prior. Telehealth resulted in 887,006 patient-miles saved and 688,317 fewer pounds of CO2 emitted. Demographics significantly associated with decreased telehealth use included Asian and Black/African American racial identity, Hispanic ethnic identity, and primary language other than English. Further distance from the hospital and higher area deprivation index were associated with increased telehealth use (IRR 1.0006 and 1.0077, respectively). CONCLUSION: Incorporating telehealth into pediatric surgical and pre anesthesia clinics resulted in significant CO2 emission reductions. Expanded telehealth use could mitigate surgical and anesthesia service contributions to climate change. Racial and linguistic minority status were associated with significantly lower rates of telehealth utilization, necessitating additional inquiry into equitable telemedicine use for minoritized populations.

Outcomes after emergency general surgery and trauma care in incarcerated individuals: An EAST multicenter study.

BACKGROUND: The US incarcerates more individuals than any other country. Prisoners are the only population guaranteed health care by the US constitution, but little is known about their surgical needs. This multicenter study aimed to describe the acute care surgery (ACS) needs of incarcerated individuals. METHODS: Twelve centers prospectively identified incarcerated patients evaluated in their emergency department by the ACS service. Centers collected diagnosis, treatment, and complications from chart review. Patients were classified as either emergency general surgery (EGS) patients or trauma patients and their characteristics and outcomes were investigated. Poisson regression accounting for clustering by center was used to calculate the relative risk (RR) of readmission, representation within 90 days, and failure to follow-up as an outpatient within 90 days for each cohort. RESULTS: More than 12 months, ACS services evaluated 943 patients, 726 (80.3%) from jail, 156 (17.3%) from prison, and 22 (2.4%) from other facilities. Most were men (89.7%) with a median age of 35 years (interquartile range, 27-47). Trauma patients comprised 54.4% (n = 513) of the cohort. Admission rates were similar for trauma (61.5%) and EGS patients (60.2%). Head injuries and facial fractures were the most common injuries, while infections were the most common EGS diagnosis. Self-harm resulted in 102 trauma evaluations (19.9%). Self-inflicted injuries were associated with increased risk of readmission (RR, 4.3; 95% confidence interval, 3.02-6.13) and reevaluation within 90 days (RR, 4.96; 95% confidence interval, 3.07-8.01). CONCLUSION: Incarcerated patients who present with a range of trauma and EGS conditions frequently require admission, and follow-up after hospitalization was low at the treating center. Poor follow-up coupled with high rates of assault, self-harm, mental health, and substance use disorders highlight the vulnerability of this population. Hospital and correctional facility interventions are needed to decrease self-inflicted injuries and assaults while incarcerated. LEVEL OF EVIDENCE: Prognostic and epidemiological, Level III.

Causes of death following discharge after trauma in North Carolina.

BACKGROUND: While a "fourth peak" of delayed trauma mortality has been described, limited data describe the causes of death (CODs) for patients in the years following an injury. This study investigates the difference in COD statewide for patients with and without a recent trauma admission. METHODS: This retrospective cohort study compared COD for trauma and nontrauma patients in North Carolina. Death certificates in NC's death registry were matched with the NC trauma registry between January 2013 and December 2018 using matching on name and date of birth. Patients who died during the index trauma admission were excluded. Underlying COD recorded on the death certificate were used for the primary analysis. RESULTS: Of 481,415 death records, 19,083 (4.0%) were linked to an alive discharge within the trauma registry during the study period. Prior trauma patients (PTPs) had a higher incidence of mental illness (9.2 vs. 6.1%), Alzheimer's (6.1% vs. 4.2%), and opioid-related (1.8% vs. 1.6%) COD compared to nontrauma patients, p < 0.05. Overall, suicide was higher in the nontrauma cohort (1.5% vs. 1.1%); however, PTP had higher incidences of death by motor vehicle collision and other injury (6.0% vs. 3.8%) and homicide (0.9% vs. 0.6%), p < 0.001. Prior trauma patients had 1.16 increased odds of an opioid-related death (p = 0.009; 95% confidence interval, 1.04-1.29) compared with those without prior trauma. Younger PTP had a much higher rate of death from suicide (12.0%) compared with those 41 to 65 years (2.8%) and older than 65 years (0.2%; p < 0.001). Discharge to skilled nursing facility (odds ratio, 1.87; p < 0.05) and severe injury (odds ratio, 1.93; p < 0.05) were associated with early death after discharge (≤90 days). CONCLUSION: After hospital discharge, PTPs remain at risk of dying from future trauma and opioid-related conditions. Prevention strategies for PTP should address the increased risk of death from a subsequent traumatic injury and the at-risk populations for early death after discharge. LEVEL OF EVIDENCE: Prognostic and Epidemiologic, Level IV.

Chronic critical illness after hypothermia in trauma patients.

OBJECTIVES: Chronic critical illness (CCI) is a phenotype that occurs frequently in patients with severe injury. Previous work has suggested that inflammatory changes leading to CCI occur early following injury. However, the modifiable factors associated with CCI are unknown. We hypothesized that hypothermia, an early modifiable factor, is associated with CCI. METHODS: To determine the association of hypothermia and CCI, a secondary analysis of the Inflammation and Host Response to Injury database was performed, and subsequently validated on a similar cohort of patients from a single level 1 trauma center from January 2015 to December 2019. Hypothermia was defined as initial body temperature ≤34.5°C. CCI was defined as death or sustained multiorgan failure ≥14 days after injury. Data were analyzed using univariable analyses with Student's t-test and Pearson's χ2 test, and logistic regression. An arrayed genomic analysis of the transcriptome of circulating immune cells was performed in these patients. RESULTS: Of the initial 1675 patients, 254 had hypothermia and 1421 did not. On univariable analysis, 120/254 (47.2%) of patients with hypothermia had CCI, compared with 520/1421 (36.6%) without hypothermia who had CCI, p<0.001. On multivariable logistic regression, hypothermia was independently associated with CCI, OR 1.61 (95% CI 1.17 to 2.21) but not mortality. Subsequent validation in 1264 patients of which 172 (13.6%) were hypothermic, verified that hypothermia was independently associated with CCI on multivariable logistic regression, OR 1.84 (95% CI 1.21 to 2.41). Transcriptomic analysis in hypothermic and non-hypothermic patients revealed unique cellular-specific genomic changes to only circulating monocytes, without any distinct effect on neutrophils or lymphocytes. CONCLUSIONS: Hypothermia is associated with the development of CCI in severely injured patients. There are transcriptomic changes which indicate that the changes induced by hypothermia may be associated with persistent CCI. Thus, early reversal of hypothermia following injury may prevent the CCI. LEVEL OF EVIDENCE: III.

We Asked the Experts: The Role of Rural Hospitals in Achieving Equitable Surgical Access in Low-Resourced Settings.

Strengthening and defining the role of rural hospitals within a surgical ecosystem is essential to improving quality and timely surgical access for rural people in low and middle-income countries (LMICs). Regional hospitals are the cornerstone of LMIC rural surgical care but have insufficient human resources and infrastructure that limit the surgical care they can provide. District hospitals are most accessible for many rural patients but also have limited surgical capacity. In order to surgical access for rural people, both regional and district hospital surgical services must be strengthened. A strong relationship between regional and district hospitals through a hub and spoke model is needed. Regional hospital surgeons can support training and supervision for and referrals from district hospitals. Telemedicine can play a key role to leapfrog physical barriers and surgical specialist shortages. The changing demographics of surgical disease will continue to worsen the strain on tertiary hospitals where most subspecialists in LMICs work. The fewer rural patients who need to travel to urban referral and tertiary facilities for problems that can be managed at lower-level facilities, the better access to timely surgical care for all.

Association of Psychosocial Factors and Hospital Complications with Risk for Readmission After Trauma.

BACKGROUND: Unplanned hospital readmissions are associated with morbidity and high cost. Existing literature on readmission after trauma has focused on how injury characteristics are associated with readmission. We aimed to evaluate how psychosocial determinants of health and complications of hospitalization combined with injury characteristics affect risk of readmission after trauma. MATERIALS AND METHODS: We conducted a retrospective cohort study of adult trauma admissions from July 2015 to September 2017 to Harborview Medical Center in Seattle, Washington. We assessed patient, injury, and hospitalization characteristics and estimated associations between risk factors and unplanned 30-d readmission using multivariable generalized linear Poisson regression models. RESULTS: Of 8916 discharged trauma patients, 330 (3.7%) had an unplanned 30-d readmission. Patients were most commonly readmitted with infection (41.5%). Independent risk factors for readmission among postoperative patients included public insurance (adjusted Relative Risk (aRR) 1.34, 95% CI 1.02-1.76), mental illness (aRR 1.39, 1.04-1.85), and chronic renal failure (aRR 2.17, 1.39-3.39); undergoing abdominal, thoracic, or neurosurgical procedures; experiencing an index hospitalization surgical site infection (aRR 4.74, 3.00-7.50), pulmonary embolism (aRR 3.38, 2.04-5.60), or unplanned ICU readmission (aRR 1.74, 1.16-2.62); shorter hospital stay (aRR 0.98/d, 0.97-0.99), and discharge to jail (aRR 4.68, 2.63-8.35) or a shelter (aRR 4.32, 2.58-7.21). Risk factors varied by reason for readmission. Injury severity, trauma mechanism, and body region were not independently associated with readmission risk. CONCLUSIONS: Psychosocial factors and hospital complications were more strongly associated with readmission after trauma than injury characteristics. Improved social support and follow-up after discharge for high-risk patients may facilitate earlier identification of postdischarge complications.

Contemporary management of traumatic cervical and thoracic esophageal perforation: The results of an Eastern Association for the Surgery of Trauma multi-institutional study.

BACKGROUND: Traumatic esophageal perforation is rare and associated with significant morbidity and mortality. There is substantial variability in diagnosis and treatment. Esophageal stents have been increasingly used for nontraumatic perforation; however, stenting for traumatic perforation is not yet standard of care. The purpose of this study was to evaluate current management of traumatic esophageal perforation to assess the frequency of and complications associated with esophageal stenting. METHODS: This was an Eastern Association for the Surgery of Trauma multi-institutional retrospective study from 2011 to 2016 of patients with traumatic cervical or thoracic esophageal injury admitted to one of 11 participating trauma centers. Data were collected and sent to a single institution where it was analyzed. Patient demographics, injury characteristics, initial management, complications, and patient mortality were collected. Primary outcome was mortality; secondary outcomes were initial treatment, esophageal leak, and associated complications. RESULTS: Fifty-one patients were analyzed. Esophageal injuries were cervical in 69% and thoracic in 31%. Most patients were initially managed with operative primary repair (61%), followed by no intervention (19%), esophageal stenting (10%), and wide local drainage (10%). Compared with patients who underwent operative primary repair, patients managed with esophageal stenting had an increased rate of esophageal leak (22.6% vs. 80.0%, p = 0.02). Complication rates were higher in blunt compared with penetrating mechanisms (100% vs. 31.8%, p = 0.03) despite similar Injury Severity Score and neck/chest/abdomen Abbreviated Injury Scale. Overall mortality was 9.8% and did not vary based on location of injury, mechanism of injury, or initial management. CONCLUSION: Most patients with traumatic esophageal injuries still undergo operative primary repair; this is associated with lower rates of postoperative leaks as compared with esophageal stenting. Patients who have traumatic esophageal injury may be best managed by direct repair and not esophageal stenting, although further study is needed. LEVEL OF EVIDENCE: Therapeutic, level IV.

Predictors of Change in Code Status from Time of Admission to Death in Critically Ill Surgical Patients.

Racial and gender disparities in end-of-life decision-making practices have not been well described in surgical patients. We performed an eight-year retrospective analysis of surgical patients within the Cerner Acute Physiology and Chronic Health Evaluation Outcomes database. ICU patients with documented admission code status, and death or ICU discharge code status, respectively, were included. Logistic regression analysis was performed to assess change in code status. Of 468,000 ICU patients, 97,968 (20.9%) were surgical, 63,567 (95%) survived, and 3,343 (5%) died during their hospitalization. Of those, 50,915 (80.1%) and 2,625 (78.5%) had complete code status data on admission and discharge or death, respectively. Women were less likely than men to remain full code at ICU discharge and death (n = 20,940, 95.6% and n = 141, 11.9% vs n = 29,320, 97.4% and n = 233, 16.3%, P < 0.001). Compared with whites, blacks and other minorities had a 0.46 odds (95% confidence interval [CI]: 0.33-0.64, P < 0.001) and 0.54 odds (95% CI: 0.34-0.85, P = 0.01) of changing from full code status before death, respectively. Before ICU discharge, blacks and other minorities had a 0.56 odds of changing from full code status when compared with whites (95% CI: 0.40-0.79, P < 0.001 vs 95% CI: 0.36-0.87, P = 0.01, respectively). Women were more likely to be discharged or die after a change in code status from full code (odds ratio 1.27, 95% CI: 1.06-1.07, P < 0.001; odds ratio 1.39, 95% CI: 1.09-1.79, P = 0.009). Men and minorities are more likely to be discharged from the ICU or die with a full code status designation.

Outcomes and prognostic factors for women with breast cancer in Malawi.

BACKGROUND: Breast cancer incidence in sub-Saharan Africa (SSA) is increasing, and SSA has the highest age-standardized breast cancer mortality rate worldwide. However, high-quality breast cancer data are limited in SSA. MATERIALS AND METHODS: We examined breast cancer patient and tumor characteristics among women in Lilongwe, Malawi and evaluated risk factor associations with patient outcomes. We consecutively enrolled 100 women ≥ 18 years with newly diagnosed, pathologically confirmed breast cancer into a prospective longitudinal cohort with systematically assessed demographic data, HIV status, and clinical characteristics. Tumor subtypes were further determined by immunohistochemistry, overall survival (OS) was estimated using Kaplan-Meier methods, and hazards ratios (HR) were calculated by Cox proportional hazard analyses. RESULTS: Of the 100 participants, median age was 49 years, 19 were HIV-positive, and 75 presented with late stage (III/IV) disease. HER2-enriched and triple-negative/basal-like subtypes represented 17% and 25% tumors, respectively. One-year OS for the cohort was 74% (95% CI 62-83%). Multivariable analyses revealed mortality was associated with HIV (HR, 5.15; 95% CI 1.58-16.76; p = 0.006), stage IV disease (HR, 8.86; 95% CI 1.07-73.25; p = 0.043), and HER2-enriched (HR, 7.46; 95% CI 1.21-46.07; p = 0.031), and triple-negative subtypes (HR, 7.80; 95% CI 1.39-43.69; p = 0.020). CONCLUSION: Late stage presentation, HER2-enriched and triple-negative subtypes, and HIV coinfection were overrepresented in our cohort relative to resource-rich settings and were associated with mortality. These findings highlight robust opportunities for population- and patient-level interventions across the entire cascade of care to improve breast cancer outcomes in low-income countries in SSA.

Secondary Overtriage of Trauma Patients to a Central Hospital in Malawi.

INTRODUCTION: Secondary overtriage (OT) is the unnecessary transfer of injured patients between facilities. In low- and middle-income countries (LMICs), which shoulder the greatest burden of trauma globally, the impact of wasted resources on an overburdened system is high. This study determined the rate and associated characteristics of OT at a Malawian central hospital. METHODS: A retrospective analysis of prospectively collected data from January 2012 through July 2017 was performed at Kamuzu Central Hospital (KCH) in Lilongwe, Malawi. Patients were considered OT if they were discharged alive within 48 h without undergoing a procedure, and were not severely injured or in shock on arrival. Factors evaluated for association with OT included patient demographics, injury characteristics, and transferring facility information. RESULTS: Of 80,915 KCH trauma patients, 15,422 (19.1%) transferred from another facility. Of these, 8703 (56.2%) were OT. OT patients were younger (median 15, IQR: 6-31 versus median 26, IQR: 11-38, p < 0.001). Patients with primary extremity injury (5308, 59.9%) were overtriaged more than those with head injury (1991, 51.8%) or torso trauma (1349, 50.8%), p < 0.001. The OT rate was lower at night (18.9% v 28.7%, p < 0.001) and similar on weekends (20.4% v 21.8%, p = 0.03). OT was highest for penetrating wounds, bites, and falls; burns were the lowest. In multivariable modeling, risk of OT was greatest for burns and soft tissue injuries. CONCLUSIONS: The majority of trauma patients who transfer to KCH are overtriaged. Implementation of transfer criteria, trauma protocols, and interhospital communication can mitigate the strain of OT in resource-limited settings.

Characteristics of Intestinal Volvulus and Risk of Mortality in Malawi.

BACKGROUND: Intestinal volvulus is a common cause of mechanical intestinal obstruction (MIO) in Africa. Sigmoid volvulus has been well characterized in both high-income and low-income countries, but there is also a predilection for small bowel volvulus in sub-Saharan Africa. METHODS: An analysis was performed of the Kamuzu Central Hospital Acute Care Surgery Registry from 2013 to 2019 on patients presenting with intestinal volvulus. Bivariate analysis was performed for covariates based on the intestinal volvulus type. Multivariate Poisson regression models estimated the relative risk of volvulus and mortality. RESULTS: A total of 4352 patients were captured in the registry. Overall, 1037 patients (23.8%) were diagnosed with MIO. Intestinal volvulus accounted for 499 (48.1%) of patients with MIO. Sigmoid volvulus, midgut volvulus, ileosigmoid knotting, and cecal volvulus accounted for 57.7% (n = 288), 19.8% (n = 99), 20.8% (n = 104), and 1.6% (n = 8), respectively. Mean age was 46.8 years (SD 17.2) with a male preponderance (n = 429, 86.0%) and 14.8% (n = 74) mortality. Overall, the most common operations performed were large bowel (n = 326, 74.4%) and small bowel (n = 76, 16.7%) resections with 18.0% (n = 90) ostomy formation. Upon regression modeling, the relative risk for volvulus was 2.7 times higher in men than women after controlling for season and age. There was no statistically significant difference in the relative risk of mortality based on the type of volvulus. CONCLUSION: Volvulus is a significant cause of primary bowel obstruction in sub-Saharan Africa. Type of intestinal volvulus is not associated increased risk of mortality. Reasons for increases in the incidence of small bowel volvulus are still largely undetermined.
