Prevalence and Severity of Burn Scars in Rural Mozambique.

BACKGROUND: Burn injuries are common in low- and middle-income countries (LMICs) and their associated disability is tragic. This study is the first to explore burn scars in rural communities in Mozambique. This work also validated an innovate burn assessment tool, the Morphological African Scar Contractures Classification (MASCC), used to determine surgical need. METHODS: Using a stratified, population-weighted survey, the team interviewed randomly selected households from September 2012 to June 2013. Three rural districts (Chókwè, Nhamatanda, and Ribáuè) were selected to represent the southern, central and northern regions of the country. Injuries were recorded, documented with photographs, and approach to care was gathered. A panel of residents and surgeons reviewed the burn scar images using both the Vancouver Scar Scale and the MASCC, a validated visual scale that categorizes patients into four categories corresponding to levels of surgical intervention. RESULTS: Of the 6104 survey participants, 6% (n = 370) reported one or more burn injuries. Burn injuries were more common in females (57%) and most often occurred on the extremities. Individuals less than 25 years old had a significantly higher odds of reporting a burn scar compared to people older than 45 years. Based on the MASCC, 12% (n = 42) would benefit from surgery to treat contractures. CONCLUSION: Untreated burn injuries are prevalent in rural Mozambique. Our study reveals a lack of access to surgical care in rural communities and demonstrates how the MASCC scale can be used to extend the reach of surgical assessment beyond the hospital through community health workers.

The Ethics and Politics of Gun Violence Research.

Gun violence is an epidemic that affects hundreds of thousands of Americans each year. Despite gun violence being disproportionately more lethal than other leading causes of trauma, there is a dearth of research being carried out on its root causes and prevention strategies. For the past 20 years, lobbying and politics have interfered with the forward progress of gun violence research. Physicians have a history of producing actionable public-health change and have an ethical obligation to fight for the research that will benefit their patients.

Rectal Injury After Foreign Body Insertion: Secondary Analysis From the AAST Contemporary Management of Rectal Injuries Study Group.

BACKGROUND: Retained rectal foreign bodies are a common but incompletely studied problem. This study defined the epidemiology, injury severity, and outcomes after rectal injuries following foreign body insertion. METHODS: Twenty-two level I trauma centers retrospectively identified all patients sustaining a rectal injury in this AAST multi-institutional trial (2005-2014). Only patients injured by foreign body insertion were included in this secondary analysis. Exclusion criteria were death before rectal injury management or ≤48 h of admission. Demographics, clinical data, and outcomes were collected. Study groups were defined as partial thickness (AAST grade I) versus full thickness (AAST grades II-V) injuries. Subgroup analysis was performed by management strategy (nonoperative versus operative). RESULTS: After exclusions, 33 patients were identified. Mean age was 41 y (range 18-57), and 85% (n = 28) were male. Eleven (33%) had full thickness injuries and 22 (67%) had partial thickness injuries, of which 14 (64%) were managed nonoperatively and 8 (36%) operatively (proximal diversion alone [n = 3, 14%]; direct repair with proximal diversion [n = 2, 9%]; laparotomy without rectal intervention [n = 2, 9%]; and direct repair alone [n = 1, 5%]). Subgroup analysis of outcomes after partial thickness injury demonstrated significantly shorter hospital length of stay (2 ± 1; 2 [1-5] versus 5 ± 2; 4 [2-8] d, P = 0.0001) after nonoperative versus operative management. CONCLUSIONS: Although partial thickness rectal injuries do not require intervention, difficulty excluding full thickness injuries led some surgeons in this series to manage partial thickness injuries operatively. This was associated with significantly longer hospital length of stay. Therefore, we recommend nonoperative management after a retained rectal foreign body unless full thickness injury is conclusively identified.

A System Dynamics Model of Violent Trauma and the Role of Violence Intervention Programs.

BACKGROUND: Violence intervention programs (VIPs) can reduce interpersonal violence (IPV); however, optimizing the implementation of VIPs is challenging, given the complex dynamics of IPV. System dynamics models (SDMs) provide a means of visualizing dynamic and causal relationships in such complex systems. We use the IPVSDM to characterize and examine the relationship between IPV, VIPs, and the social determinants of health (SDH). MATERIALS AND METHODS: The simulation model was created from a diagram that links putative causal relationships between VIPs, SDH, and IPV events. Simulation rules are then used to calculate a risk of violence parameter based on the SDH, which drives the transition from low-risk to high-risk populations and in turn influences IPV event rates. A qualitative relational approach was used to evaluate long-term effects of VIP on IPV events. RESULTS: The model produced qualitatively plausible behavior with respect to IPV events, population transitions, and relative overall VIP effect. Simulation runs converged to stable steady states with an exponential benefit of VIP on reducing IPV that is best appreciated after 1-2 y. The VIP functioned in a recognizable fashion by slowing the shift from low-risk to high-risk populations. CONCLUSIONS: This initial implementation of the IPVSDM produced recognizable baseline behavior while incorporating the possible effects of a VIP. The model allows causality and counterfactual testing, which is impractical in vivo. Community-level VIP efforts should show benefit particularly after a couple years. Future work will emphasize adding complexity to the IPVSDM and identifying real-world metrics to aid in testing, validation, and prediction of the model.

Traumatic rectal injuries: Is the combination of computed tomography and rigid proctoscopy sufficient?

BACKGROUND: There are no clear guidelines for the best test or combination of tests to identify traumatic rectal injuries. We hypothesize that computed tomography (CT) and rigid proctoscopy (RP) will identify all injuries. METHODS: American Association for the Surgery of Trauma multi-institutional retrospective study (2004-2015) of patients who sustained a traumatic rectal injury. Patients with known rectal injuries who underwent both CT and RP as part of their diagnostic workup were included. Only patients with full thickness injuries (American Association for the Surgery of Trauma grade II-V) were included. Computed tomography findings of rectal injury, perirectal stranding, or rectal wall thickening and RP findings of blood, mucosal abnormalities, or laceration were considered positive. RESULTS: One hundred six patients were identified. Mean age was 32 years, 85(79%) were male, and 67(63%) involved penetrating mechanisms. A total of 36 (34%) and 100 (94%) patients had positive CT and RP findings, respectively. Only 3 (3%) patients had both a negative CT and negative RP. On further review, each of these three patients had intraperitoneal injuries and had indirect evidence of rectal injury on CT scan including pneumoperitoneum or sacral fracture. CONCLUSION: As stand-alone tests, neither CT nor RP can adequately identify traumatic rectal injuries. However, the combination of both test demonstrates a sensitivity of 97%. Intraperitoneal injuries may be missed by both CT and RP, so patients with a high index of suspicion and/or indirect evidence of rectal injury on CT scan may necessitate laparotomy for definitive diagnosis. LEVEL OF EVIDENCE: Diagnostic, level IV.

Contemporary management of rectal injuries at Level I trauma centers: The results of an American Association for the Surgery of Trauma multi-institutional study.

INTRODUCTION: Rectal injuries have been historically treated with a combination of modalities including direct repair, resection, proximal diversion, presacral drainage, and distal rectal washout. We hypothesized that intraperitoneal rectal injuries may be selectively managed without diversion and the addition of distal rectal washout and presacral drainage in the management of extraperitoneal injuries are not beneficial. METHODS: This is an American Association for the Surgery of Trauma multi-institutional retrospective study from 2004 to 2015 of all patients who sustained a traumatic rectal injury and were admitted to one of the 22 participating centers. Demographics, mechanism, location and grade of injury, and management of rectal injury were collected. The primary outcome was abdominal complications (abdominal abscess, pelvic abscess, and fascial dehiscence). RESULTS: After exclusions, there were 785 patients in the cohort. Rectal injuries were intraperitoneal in 32%, extraperitoneal in 58%, both in 9%, and not documented in 1%. Rectal injury severity included the following grades I, 28%; II, 41%; III, 13%; IV, 12%; and V, 5%. Patients with intraperitoneal injury managed with a proximal diversion developed more abdominal complications (22% vs 10%, p = 0.003). Among patients with extraperitoneal injuries, there were more abdominal complications in patients who received proximal diversion (p = 0.0002), presacral drain (p = 0.004), or distal rectal washout (p = 0.002). After multivariate analysis, distal rectal washout [3.4 (1.4-8.5), p = 0.008] and presacral drain [2.6 (1.1-6.1), p = 0.02] were independent risk factors to develop abdominal complications. CONCLUSION: Most patients with intraperitoneal injuries undergo direct repair or resection as well as diversion, although diversion is not associated with improved outcomes. While 20% of patients with extraperitoneal injuries still receive a presacral drain and/or distal rectal washout, these additional maneuvers are independently associated with a three-fold increase in abdominal complications and should not be included in the treatment of extraperitoneal rectal injuries. LEVEL OF EVIDENCE: Therapeutic study, level III.

Improving surgical systems in low- and middle-income countries: an inclusive framework for monitoring and evaluation.

High disease burden and inadequate resources have formed the basis for advocacy to improve surgical care in low- and middle-income countries (LMICs). Current measures are heavily focused on availability of resources rather than impact and fail to fully describe how surgery can be more integrated into health systems. We propose a new monitoring and evaluation framework of surgical care in LMICs to integrate surgical diseases into broader health system considerations and track efforts toward improved population health. Although more discussion is required, we seek to broaden the dialogue of how to improve surgical care in LMICs through this comprehensive framework.

Surgical Care and Health Systems.

BACKGROUND: While surgical care impacts a wide variety of diseases and conditions with non-operative and operative services, both preventive and curative, there has been little discussion concerning how surgery might be integrated within the health system of a low and middle-income country (LMIC), nor how strengthening surgical services may improve health systems and population health. METHODS: We reviewed reports from several meetings of the working group on health systems strengthening of the Global Initiative for Emergency and Essential Surgical Care, and also performed a review of the literature including the search terms "surgery," "health system," "developing country," "health systems strengthening," "health information system," "financing," "governance," and "integration." RESULTS: The literature search revealed no reports which focused on the integration of surgical services within a health system or as a component of health system strengthening. A conceptual model of how surgical care might be integrated within a health system is proposed, based on the discussions of our working group, combined with sources from the medical literature, and utilizing the World Health Organization's conceptual model of a health system. CONCLUSIONS: Strengthening the delivery of surgical services in LMICs will require inputs at multiple levels within a health system, and this effort will require the coalescence of committed individuals and organizations, supported by civil society.

Surgical patients travel longer distances than non-surgical patients to receive care at a rural hospital in Mozambique.

BACKGROUND: Surgical care is increasingly recognised as an important component of global health delivery. However, there are still major gaps in knowledge related to access to surgical care in low-income countries. In this study, we compare distances travelled by surgical patients with patients seeking other medical services at a first-level hospital in rural Mozambique. METHODS: Data were collected on all inpatients at Hospital Rural de Chókwè in rural Mozambique between 20 June 2012 and 3 August 2012. Euclidean distances travelled by surgical versus non-surgical patients using coordinates of each patient's city of residence were compared. Data were analysed using ArcGIS 10 and STATA. RESULTS: In total, 500 patients were included. Almost one-half (47.6%) lived in the city where the hospital is based. By hospital ward, the majority (62.0%) of maternity patients came from within the hospital's city compared with only 35.2% of surgical patients. The average distance travelled was longest for surgical patients (42 km) compared with an average of 17 km for patients on all other wards. CONCLUSIONS: Patients seeking surgical care at this first-level hospital travel farther than patients seeking other services. While other patients may have access to at community clinics, surgical patients depend more heavily on the services available at first-level hospitals.

Surgical conditions account for the majority of admissions to three primary referral hospitals in rural Mozambique.

BACKGROUND: The World Health Organization has identified the primary referral hospital as its priority site for improving surgical care in low- and middle-income countries. Little is known about the relative burden surgical patients place on health care facilities at this level. This research estimates the fraction of admissions due to surgical conditions at three hospitals in rural Mozambique. METHODS: Prospective data were collected on all inpatients at three primary referral hospitals in Mozambique during a 12-day period. We compared the number of surgical patients and their length of stay (LOS) to the patients admitted to the medicine, pediatric, and maternity wards. These findings were validated using retrospective data collected from one hospital from January to May 2012. RESULTS: Patients with surgical conditions (i.e., patients admitted to the surgical or maternity ward) accounted for 57.5 % of admissions and 48.0 % of patient-days. The majority of patients were admitted to the maternity ward (32.3 %). The other admissions were evenly distributed to the pediatric (22.5 %), medical (20.0 %), and surgical (25.2 %) wards. Compared to patients from the three other wards, surgical patients had longer average LOS (8.7 vs. 1.9-7.7 days) and a higher number of total patient-days (891 vs. 252-703 days). The most prevalent procedures were cesarean section (33.3 %) and laceration repair/wound care (11.8 %). CONCLUSIONS: Surgical conditions are the most common reason for admissions at three primary referral hospitals in rural Mozambique. These data suggest that surgical care is a major component of health care delivered at primary referral hospitals in Mozambique and likely other sub-Saharan African countries.
