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.

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.

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.

Inpatient Mortality Among Patients With Acute Respiratory Distress Syndrome at ECMO and Non-ECMO Centers in the United States.

BACKGROUND: A 2009 randomized control trial found patients with severe acute respiratory distress syndrome (ARDS) who transferred to an extra-corporeal membrane oxygenation therapy (ECMO) center had better survival, even if they did not receive ECMO. This study aimed to use a national US database to determine if care at ECMO centers offer a survival advantage in patients with ARDS with mechanical ventilation only. METHODS: Hospitalizations of patients 18-64 years old who had ARDS and mechanical ventilation in the 2010-2016 Health care Cost and Utilization Project National Readmission Database were included. ECMO centers performed at least 1 veno-venous ECMO hospitalization annually; or >5, >20, and >50 on sensitivity analysis. Multivariable logistic regression compared inpatient mortality, after adjusting for timing of hospitalization, patient demographics, comorbidities, and hospital characteristics. RESULTS: Of the 1 224 447 ARDS hospitalizations and mechanical ventilation, 41% were at ECMO centers. ECMO centers were more likely to be larger, private, non-profit, teaching hospitals. ARDS at admission was more common at non-ECMO centers (31% vs 23%, P < .0001); however, other patient demographics and comorbidities did not differ. After adjustment, no difference in inpatient mortality was seen between ECMO and non-ECMO centers (OR 0.99, 95% CI: 0.97, 1.02). This relationship did not change in sensitivity analyses. DISCUSSION: Adult patients with ARDS requiring mechanical ventilation may not have improved outcomes if treated at an ECMO center and suggest that early transfer of all ARDS patients to ECMO centers may not be warranted. Further evaluation of ECMO center volume and illness severity is needed.

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. LEVEL OF EVIDENCE: Level IV.

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.

"Low initial pre-hospital end-tidal carbon dioxide predicts inferior clinical outcomes in trauma patients".

INTRODUCTION: Current guidelines continue to lead to under- and over-triage of injured patients in the pre-hospital setting. End-tidal carbon dioxide (ETCO2) has been correlated with mortality and hemorrhagic shock in trauma patients. This study examines the correlation between ETCO2 and in-hospital outcomes among non-intubated patients in the pre-hospital setting. METHODS: We retrospectively studied a cohort of non-intubated adult trauma patients with initial pre-hospital side-stream capnography-obtained ETCO2 presenting via ground transport from a single North Carolina EMS agency to a level one trauma center from January 2018 to December 2018. Using the Liu method, the optimal threshold for low ETCO2 was ≤ 28.5 mmHg. RESULTS: Initial pre-hospital ETCO2 was recorded for 324 (22.0%) of 1473 patients with EMS data. Patients with low ETCO2 (N = 98, 30.3% of cohort) were older (median 58y vs 45y), but mechanisms of injury and scene vital signs were similar (p>0.05) between low and normal/high ETCO2 cohorts. Median injury severity score (ISS) did not differ significantly between the low and normal/high ETCO2 groups (5 vs 8, p=0.48). Compared to normal/high ETCO2, low ETCO2 correlated with increased unadjusted odds of mortality (OR 5.06), in-hospital complications (OR 2.06), and blood transfusion requirement (OR 3.05), p<0.05. Low ETCO2 was associated with 7.25 odds of mortality (95% CI 2.19,23.97, p=0.001) and 3.94 odds of blood transfusion (95% CI 1.32-11.78) after adjusting for age, ISS, and scene GCS. All but one of the massive transfusion patients (N = 8/9) had a low pre-hospital ETCO2. CONCLUSIONS: Low initial pre-hospital ETCO2 associates with poor clinical outcomes despite similar ISS and mechanisms of injury. ETCO2 is a potentially useful pre-hospital point-of-care tool to aid triage of trauma patients as it may identify hemorrhaging patients and predict mortality.

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.

Veno-Venous Extracorporeal Membrane Oxygenation for Acute Respiratory Distress Syndrome During Hemorrhagic Shock.

Despite overall improvements in critical care, mortality from acute respiratory distress syndrome (ARDS) remains high. Veno-venous extracorporeal membrane oxygenation (V-V ECMO) is used to rescue patients with severe ARDS. Although V-V ECMO can be life-saving, there are significant risks associated with this therapy. Hemorrhage is one of the most common complications. Therefore, some providers are reluctant to use V-V ECMO in patients with severe ARDS who concurrently have a high risk of bleeding or recent active hemorrhage. Several studies have been published detailing the safety of heparin-sparing or completely heparin-free anticoagulation strategies in patients on V-V ECMO. We present the cases of two patients with hemorrhagic shock and ongoing transfusion requirements who developed severe and refractory ARDS while in the operating room for hemorrhage control. After the massive bleeding was stopped, both patients were placed on V-V ECMO and were managed with minimal or no therapeutic anticoagulation for the duration of their course on V-V ECMO. Both patients required multiple operations and procedures while on V-V ECMO and there were no significant hemorrhagic complications. In conclusion, V-V ECMO can be considered for use in select patients with severe ARDS and high risk of hemorrhage, active hemorrhage, or ongoing transfusion requirements.

The impact of data feedback on continuous quality improvement projects in Rwanda: A mixed methods analysis.

BACKGROUND: Injuries are a leading cause of death and disability globally. Over 90% of injury-related mortality happens in low- and middle- income countries (LMICs). Rwanda's pre-hospital emergency system - Service d'Aide Medicale Urgente (SAMU) - and their partners created an electronic pre-hospital registry and Continuous Quality Improvement (CQI) project in 2014. The CQI showed progress in quality of care, sparking interest in factors enabling the project's success. Healthcare workers (HCW) are critical pieces of this success, yet we found a void of information linking pre-hospital HCW motivation to CQI programs like SAMU's. METHODS: Our mixed methods approach included a 40-question survey using questions regarding HCW motivation. We scored the surveys to compare SAMU staff motivation with other HCWs in LMICs, and used a Likert scale to elicit agreement or disagreement. A semi-structured interview based on employee motivation theory qualitatively explored SAMU staff motivation using constructivist grounded theory. To find interview themes, two researchers independently performed line-by-line analysis. RESULTS: SAMU staff received 5-21% higher motivation scores relative to other cohorts of HCWs in LMICs. Questions showing disagreement (five) asked about reprimand, damaged social standing, and ease of using the CQI technology. Three questions did not show consensus. Questions showing agreement (23) and strong agreement (nine) asked about organizational commitment, impact, and research improving patient care. Major themes were: improvements in quality of care, changes in job expectations, views on research, and positive experiences with data feedback. CONCLUSIONS: The CQI project provides constant feedback vital to building and sustaining successful health systems. It encourages communication, collaboration, and personal investment, which increase organizational commitment. Continuous feedback provides opportunities for personal and professional development by uncovering gaps in knowledge, patient care, and technological understanding. Complete, personalized data input encouraged by the CQI improves resource allocation, building robust health systems that improve HCW agency and motivation.

Does Level of Blood Alcohol Content Affect Clinical Outcomes After Trauma in Older Adult Patients?

INTRODUCTION: Preinjury alcohol use and older age have independently been associated with poor outcomes. This study examined whether higher levels of blood alcohol concentration (BAC) correlated with an increased likelihood of poor outcomes in older trauma patients. METHODS: This was a retrospective cohort study of injured patients ≥65 years with BAC testing presenting to a Level 1 trauma center between 2015 and 2018. Patients were stratified by BAC at 4 thresholds of intoxication: BAC ≧10 mg/dL, BAC ≧80 mg/dL, BAC ≧150 mg/dL, and BAC ≧200 mg/dL. Propensity score matching using inverse probability of treatment weighting was used to estimate outcomes. Logistic and Poisson regression models were performed for each threshold of the BAC level with the matched cohort to assess clinical outcomes. RESULTS: Of all older patients (n = 3112), 32.5% (n = 1012) had BAC testing. In the matched cohort of 883 patients (76.7 ± 8.2 years; 48.1% female), 111 (12.5%) had BAC ≧10 mg/dL, 83 (74.8%) had BAC ≧80 mg/dL, 60 (54.1%) had BAC ≧150 mg/dL, and 37 (33.3%) had BAC ≧200 mg/dL. Falls (60.5%) and motor vehicle crashes (28.9%) were the most common mechanisms of injury. Median (IQR) of Injury Severity Score (ISS) was 5 (1-10). The risk of severe injury (ISS ≧15) was similar between alcohol-positive and alcohol-negative patients (9.9% vs 15.0%, P = .151). BAC ≧10 g/dL was not associated with length of stay, intensive care unit admission, or in-hospital complication, nor was any of the other 3 analyzed BAC thresholds. CONCLUSION: Overall, any detectable BAC along and increasing thresholds of BAC was not associated with poor in-hospital outcomes of older patients after trauma. Alcohol screening was low in this population, and intoxication may bias injury assessment, leading to mistriage of older trauma patients.

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.

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.

Comparison of Traditional and Skin-Sparing Approaches for Surgical Treatment of Necrotizing Soft-Tissue Infections.

Background: A skin-sparing approach for the treatment of necrotizing soft-tissue infections (NSTIs) removes necrotic tissue planes while leaving viable overlying skin. Subsequent closure of the spared skin may decrease the need for graft-based reconstruction, which is associated with contracture, pain, and deformity. This study compared the outcomes of a traditional approach (excision of overlying skin with diseased fascia) with that of a skin-sparing approach for patients with NSTI treated at a major metropolitan medical center. Methods: Demographic, clinical, and operative details for patients treated for NSTI between July 2012 and December 2016 at a single institution were reviewed retrospectively. Pre-operative and post-operative photographs were evaluated independently by three surgeons to determine reconstructive outcomes. Cohen's κ was used to assess inter-rater reliability. Multiple regression and Poisson regression models were used to assess the association between outcomes and the surgical approach. Results: A total of 487 patients were divided into two cohorts: Traditional approach (TA), treated between July 2012 and December 2014 (n = 230), and skin-sparing approach (SS), treated after January 2015 (n = 257). The mortality rate in the two groups was equal at approximately 10%. The median percentage of each wound closed by skin graft was significantly lower for the SS group than for the TA group (20% versus 90%; p < 0.0001) with a correspondingly higher median percentage of primary skin closure for the SS group (50% versus 0; p < 0.0001). Conclusions: Relative to traditional debridement, skin-sparing debridement for source control of NSTI results in significantly more wounds closed completely by delayed primary suture of existing skin flaps and a significantly lower overall wound percentage closed by skin graft, while demonstrating equivalent efficacy of source control and a similar low mortality rate.

Improving Access to Laparoscopy in Low-Resource Settings.

Laparoscopy has numerous clinical benefits compared to laparotomy. However, a functional laparoscopy program requires significant investment and, as a result, remains unavailable for the majority of the world's population in low- and middle-income countries. The effort to bring laparoscopy to low-resource settings has produced variable outcomes resulting from the challenges inherent to a complex surgical program. This paper highlights these shortcomings and identifies opportunities to improve future laparoscopy programs.

Complications and 3-month outcomes of children with hydrocephalus treated with ventriculoperitoneal shunts in Malawi.

OBJECTIVE: Hydrocephalus is the most common pediatric neurosurgical condition, with a high prevalence in low- and middle-income countries. Untreated, hydrocephalus leads to neurological disability or death. The epidemiology and outcomes of hydrocephalus treated by ventriculoperitoneal (VP) shunts in Sub-Saharan Africa are not well defined and vary by region. The aim of the present study was to examine the mortality and morbidity rates and predictors of mortality in children treated by VP shunt placement for hydrocephalus at Kamuzu Central Hospital in Lilongwe, Malawi. METHODS: This is a prospective study of 100 consecutive children presenting with hydrocephalus who were treated with VP shunt placement from January 2015 to August 2017. Demographics, nutritional status, maternal characteristics, developmental delay, shunt complications, readmissions, and in-hospital and 3-month mortality data were collected. Multivariate logistic regression was used to identify predictors of death within 3 months of surgery. RESULTS: Overall, 46% of participants were female, with an average age of 5.4 ± 3.7 months at the time of surgery. The majority of patients were term deliveries (87.8%) and were not malnourished (72.9%). Only 10.8% of children were diagnosed with meningitis before admission. In-hospital and 3-month mortality rates were 5.5% and 32.1%, respectively. The only significant association with mortality was maternal age, with older maternal age demonstrating decreased odds of 3-month mortality (OR 0.9, 95% CI 0.8-1.0, p = 0.045). CONCLUSIONS: Surgical management of hydrocephalus with VP shunts portends a high mortality rate in Malawi. The association of younger maternal age with mortality is likely a proxy for social determinants, which appear to contribute as much to mortality as patient factors. VP shunting is inadequate as a sole surgical management of hydrocephalus in resource-limited settings.
