Surgical skills needed for humanitarian missions in resource-limited settings: Common operative procedures performed at Médecins Sans Frontières facilities

BACKGROUND Surgeons in high-income countries increasingly are expressing interest in global surgery and participating in humanitarian missions. Knowledge of the surgical skills required to adequately respond to humanitarian emergencies is essential to prepare such surgeons and plan for interventions. METHODS A retrospective review of all surgical procedures performed at Médecins Sans Frontières Brussels facilities from June 2008 to December 2012 was performed. Individual data points included country of project; patient age and sex; and surgical indication and surgical procedure. RESULTS Between June 2008 and December 2012, a total of 93,385 procedures were performed on 83,911 patients in 21 different countries. The most common surgical indication was for fetal-maternal pathologies, accounting for 25,548 of 65,373 (39.1%) of all cases. The most common procedure was a Cesarean delivery, accounting for a total of 24,182 or 25.9% of all procedures. Herniorrhaphies (9,873/93,385, 10.6%) and minor surgeries (11,332/93,385, 12.1%), including wound debridement, abscess drainage and circumcision, were also common. CONCLUSION A basic skill set that includes the ability to provide surgical care for a wide variety of surgical morbidities is urgently needed to cope with the surgical need of humanitarian emergencies. This review of Médecins Sans Frontièress operative procedures provides valuable insight into the types of operations with which an aspiring volunteer surgeon should be familiar.

Prioritizing injury care: a review of trauma capacity in low and middle-income countries

BACKGROUND Trauma is a large contributor to the global burden of disease, particularly in low and middle-income countries (LMICs). This study aimed to summarize the literature assessing surgical capacity in LMICs to provide a current assessment of trauma capacity, which will help guide future efforts. MATERIALS AND METHODS The MEDLINE database was queried via PubMed to identify studies assessing baseline surgical capacity in individual LMICs. Data were collected from each study by extracting the relevant information from the full-published text or tables. Trauma capacity was evaluated using 12 surrogate criteria of trauma care, including laparotomy, cricothyroidotomy and chest tube insertion capabilities, and accessibility to a blood bank. RESULTS Seventeen studies were reviewed, documenting data from 531 hospitals in seventeen countries. None of the countries had access to all twelve trauma criteria in all their hospitals. Endotracheal intubation and cricothyrotomy or tracheostomy were available at 48% (107/222) and 41% (163/418) of facilities, respectively. Bag mask valves were available at 61% (234/383) of the institutions. Although 87% (193/221) of facilities responded that they were able to provide initial resuscitation, only 48% (169/349) of them had access to a blood bank and 70% (191/271) had access to intravenous fluids. A third or less of district hospitals had access to basic resuscitation (33%; 8/24), endotracheal tubes (32%; 31/97), blood banks (31%; 32/102), and cricothyrotomies and/or tracheostomies (32%; 30/95). CONCLUSIONS Deficiencies in trauma capacity in LMICs remain widespread. This study provides specific avenues for improved evaluations of trauma capacity and for strengthening trauma systems in LMICs.

Burn management capacity in low and middle-income countries: A systematic review of 458 hospitals across 14 countries

IMPORTANCE More than 90% of thermal injury-related deaths occur in low-resource settings. While baseline assessment of burn management capabilities is necessary to guide capacity building strategies, limited data exist from low and middle-income countries (LMICs). OBJECTIVE The objective of our review is to assess burn management capacity in LMICs. EVIDENCE REVIEW A PubMed literature review was performed based on studies assessing baseline surgical capacity in individual LMICs. Seven criteria were used to assess burn management capabilities: presence of surgeon, presence of anesthesiologist, basic resuscitation capabilities, acute burn management, management of burn complications, endotracheal intubation and skin grafts. FINDINGS Fourteen studies were reviewed using data from 458 hospitals in fourteen countries. Of these, 82.3% (284/345) of hospitals had the capacity to provide basic resuscitation and 84.9% (275/324) were capable of providing acute burn management. Endotracheal intubation was only available at 38.3% (51/133) of hospitals. Moreover, only 35.6% (111/312) and 37.9% (120/317) of hospitals were able to provide skin grafts and treat burn complications, respectively. CONCLUSION Many hospitals in LMICs are capable of initial burn management and basic resuscitation. However, deficiencies still exist in the capacity to systematically provide advanced burn care. Efforts should be made to better document resources in order to guide burn management resource allocation.

Association of severity of illness and intensive care unit readmission: A systematic review

OBJECTIVES To determine whether ICU readmission is associated with higher severity of illness scores in adult patients. BACKGROUND Readmissions to the intensive care unit (ICU) are associated with increased costs, morbidity, and mortality. METHODS We performed searches of MEDLINE, EMBASE, and grey literature databases. We selected studies reporting data from adults who were hospitalized in an ICU, received severity of illness scores, and were discharged from the ICU. Characteristics of readmitted and non-readmitted patients were examined. RESULTS We screened 4766 publications and included 31 studies in our analysis. In most studies, severity of illness scores were higher in patients readmitted to the ICU. Readmission was also associated with higher mortality and longer ICU and hospital stays. Excessive heterogeneity precluded the reporting of results in the form of a meta-analysis. CONCLUSIONS ICU readmission is associated with higher severity of illness scores during the same hospitalization in adult patients.

Burns in Sierra Leone: A population-based assessment

PURPOSE Burns remain disproportionately prevalent in developing countries. This study aims to describe the epidemiology of burns in Sierra Leone to serve as a baseline for future programs. METHODS A cluster randomized, cross-sectional, countrywide survey was conducted in 2012 in Sierra Leone. With a standardized questionnaire demographics and deaths during the previous 12 months of household members were assessed with the household representative. Thereafter, 2 randomly selected household members were interviewed, elucidating whether participants had ever had a burn in six body regions and determining burn mechanisms and patterns of health care seeking behavior. RESULTS This study included 1843 households and 3645 individuals. 3.98% (145/3645) of individuals reported at least one burn-injury. The highest proportions of burns were reported in the age groups 0-4 years old (23/426, 5.4%) and 5-14 years old (37/887, 4.17%). The majority of burns (129/145, 89.0%) were caused by a hot liquid/object and the upper, extremities were the most commonly burned body regions, with 36% (53/145) of cases. 21% (30/145) of individuals with burns sought care from a traditional healer. CONCLUSIONS Burns are highly prevalent in Sierra Leone. Further research and resources should be allocated to the care and prevention of thermal injuries.

Providing Anesthesia Care in Resource-limited Settings: A 6-year Analysis of Anesthesia Services Provided at Médecins Sans Frontières Facilities

Background:Anesthesia is integral to improving surgical care in low-resource settings. Anesthesia providers who work in these areas should be familiar with the particularities associated with providing care in these settings, including the types and outcomes of commonly performed anesthetic procedures. Methods:The authors conducted a retrospective analysis of anesthetic procedures performed at Médecins Sans Frontières facilities from July 2008 to June 2014. The authors collected data on patient demographics, procedural characteristics, and patient outcome. The factors associated with perioperative mortality were analyzed. Results:Over the 6-yr period, 75,536 anesthetics were provided to adult patients. The most common anesthesia techniques were spinal anesthesia (45.56%) and general anesthesia without intubation (33.85%). Overall perioperative mortality was 0.25%. Emergent procedures (0.41%; adjusted odds ratio [AOR], 15.86; 95% CI, 2.14 to 115.58), specialized surgeries (2.74%; AOR, 3.82; 95% CI, 1.27 to 11.47), and surgical duration more than 6 h (9.76%; AOR, 4.02; 95% CI, 1.09 to 14.88) were associated with higher odds of mortality than elective surgeries, minor surgeries, and surgical duration less than 1 h, respectively. Compared with general anesthesia with intubation, spinal anesthesia, regional anesthesia, and general anesthesia without intubation were associated with lower perioperative mortality rates of 0.04% (AOR, 0.10; 95% CI, 0.05 to 0.18), 0.06% (AOR, 0.26; 95% CI, 0.08 to 0.92), and 0.14% (AOR, 0.29; 95% CI, 0.18 to 0.45), respectively. Conclusions:A wide range of anesthetics can be carried out safely in resource-limited settings. Providers need to be aware of the potential risks and the outcomes associated with anesthesia administration in these settings.

Surgery for Conditions of Infectious Etiology in Resource-Limited Countries Affected by Crisis: The Médecins Sans Frontières Operations Centre Brussels Experience

BACKGROUND Surgery for infection represents a substantial, although undefined, disease burden in low- and middle-income countries (LMICs). Médecins Sans Frontières-Operations Centre Brussels (MSF-OCB) provides surgical care in LMICs and collects data useful for describing operative epidemiology of surgical need otherwise unmet by national health services. This study aimed to describe the experience of MSF-OCB operations for infections in LMICs. By doing so, the results might aid effective resource allocation and preparation of future humanitarian staff. METHODS Procedures performed in operating rooms at facilities run by MSF-OCB from July 2008 through June 2014 were reviewed. Projects providing specialty care only were excluded. Procedures for infection were described and related to demographics and reason for humanitarian response. RESULTS A total of 96,239 operations were performed at 27 MSF-OCB sites in 15 countries between 2008 and 2014. Of the 61,177 general operations, 7,762 (13%) were for infections. Operations for skin and soft tissue infections were the most common (64%), followed by intra-abdominal (26%), orthopedic (6%), and tropical infections (3%). The proportion of operations for skin and soft tissue infections was highest during natural disaster missions (p<0.001), intra-abdominal infections during hospital support missions (p<0.001) and orthopedic infections during conflict missions (p<0.001). CONCLUSION Surgical infections are common causes for operation in LMICs, particularly during crisis. This study found that infections require greater than expected surgical input given frequent need for serial operations to overcome contextual challenges and those associated with limited resources in other areas (e.g., ward care). Furthermore, these results demonstrate that the pattern of operations for infections is related to nature of the crisis. Incorporating training into humanitarian preparation (e.g., surgical sepsis care, ultrasound-guided drainage procedures) and ensuring adequate resources for the care of surgical infections are necessary components for providing essential surgical care during crisis.

Promoting quality of care in disaster response: A survey of core surgical competencies

BACKGROUND Recent humanitarian crises have led to a call for professionalization of the humanitarian field, but core competencies for the delivery of surgical care have yet to be established. The objective of this study was to survey surgeons with experience in disaster response to identify surgical competencies required to be effective in these settings. METHODS An online survey elucidating demographic information, scope of practice, and previous experience in global health and disaster response was transmitted to surgeons from a variety of surgical societies and nongovernmental organizations. Participants were provided with a list of 111 operative procedures and were asked to identify those deemed essential to the toolset of a frontline surgeon in disaster response via a Likert scale. Responses from personnel with experience in disaster response were contrasted with those from nonexperienced participants. RESULTS A total of 147 surgeons completed the survey. Participants held citizenship in 22 countries, were licensed in 30 countries, and practiced in >20 countries. Most respondents (56%) had previous experience in humanitarian response. The majority agreed or strongly agreed that formal training (54%), past humanitarian response (94%), and past global health experiences (80%) provided adequate preparation. The most commonly deemed important procedures included control of intraabdominal hemorrhage (99%), abdominal packing for trauma (99%), and wound debridement (99%). Procedures deemed important by experienced personnel spanned multiple specialties. CONCLUSION This study addressed specifically surgical competencies in disaster response. We provide a list of operative procedures that should set the stage for further structured education programs.
