Comprehensive national analysis of emergency and essential surgical capacity in Rwanda

Disparities in the global availability of operating theatres, essential surgical equipment and surgically trained providers are profound. Although efforts are ongoing to increase surgical care and training, little is known about the surgical capacity in developing countries. The aim of this study was to create a baseline for surgical development planning at a national level.

Estimating operative disease prevalence in a low-income country: results of a nationwide population survey in Rwanda.

BACKGROUND Operative disease is estimated to contribute to 11% of the global burden of disease, but no studies have correlated this figure to operative burden at the community level. We describe a survey tool that evaluates population-based prevalence of operative conditions and its first full-country implementation in Rwanda. METHODS The Surgeons OverSeas Assessment of Surgical Need (SOSAS) survey tool is a cross-sectional, cluster-based population survey designed to measure conditions that may necessitate an operative consultation or intervention. Household surveys in Rwanda were conducted in October 2011 in 52 clusters nationwide. Data were population-weighted and analyzed with the use of descriptive statistics. RESULTS A total of 1626 households (3175 individuals) were sampled with a 99% response rate. 41.2% (95% confidence interval [95 CI%] 38.8-43.6%) of the population has had at least one operative condition during their lifetime, 14.8% (95% CI 13.3-16.5%) had an operative condition during the previous 12 months, and 6.4% (95% CI 5.6-7.3%) of the population were determined to have a current operative condition. A total of 55.3% of the current operative need was found in female respondents and 40.3% in children younger than 15 years of age. A total of 32.9% of household deaths in the previous year may have been related to operative conditions, and 55.0% of responding households lacked funds for transport to the nearest hospital providing general practitioner operative services. CONCLUSION The SOSAS survey tool provides important insight into the burden of operative disease in the community. Our results show a high need for operative care, which has important implications for the global operative community as well as for local health system strengthening in Rwanda.

Hypocaloric compared with eucaloric nutritional support and its effect on infection rates in a surgical intensive care unit: a randomized controlled trial

BACKGROUND Proper caloric intake goals in critically ill surgical patients are unclear. It is possible that overnutrition can lead to hyperglycemia and an increased risk of infection. OBJECTIVE This study was conducted to determine whether surgical infection outcomes in the intensive care unit (ICU) could be improved with the use of hypocaloric nutritional support. DESIGN Eighty-three critically ill patients were randomly allocated to receive either the standard calculated daily caloric requirement of 25-30 kcal · kg(-1) · d(-1) (eucaloric) or 50% of that value (hypocaloric) via enteral tube feeds or parenteral nutrition, with an equal protein allocation in each group (1.5 g · kg(-1) · d(-1)). RESULTS There were 82 infections in the hypocaloric group and 66 in the eucaloric group, with no significant difference in the mean (± SE) number of infections per patient (2.0 ± 0.6 and 1.6 ± 0.2, respectively; P = 0.50), percentage of patients acquiring infection [70.7% (29 of 41) and 76.2% (32 of 42), respectively; P = 0.57], mean ICU length of stay (16.7 ± 2.7 and 13.5 ± 1.1 d, respectively; P = 0.28), mean hospital length of stay (35.2 ± 4.9 and 31.0 ± 2.5 d, respectively; P = 0.45), mean 0600 glucose concentration (132 ± 2.9 and 135 ± 3.1 mg/dL, respectively; P = 0.63), or number of mortalities [3 (7.3%) and 4 (9.5%), respectively; P = 0.72]. Further analyses revealed no differences when analyzed by sex, admission diagnosis, site of infection, or causative organism. CONCLUSIONS Among critically ill surgical patients, caloric provision across a wide acceptable range does not appear to be associated with major outcomes, including infectious complications. The optimum target for caloric provision remains elusive.

Engaging academic surgery in global health: Challenges and opportunities in the development of an academic track in global surgery

SURGERY is not thought of typically as a component of public health, especially in resource-poor countries in which much of the medical attention is placed on prevention and treatment of infectious diseases. Current avenues of financial support for research and health initiatives in lowand middle-income countries often focus on health issues targeted by the United Nations Millennium Development Goals, such as HIV/AIDS, malaria, tuberculosis, and maternal and child health. It has been estimated that

0.83 in research dollars are spent per DALY caused by road traffic accidents. This marked discrepancy is true despite the reality that operatively treatable disease accounts for at least 11% of the global burden of disease and greater than 25 million DALYs. In the United States and elsewhere, it is well understood that injuries are the leading cause of morbidity and mortality in children and young adults. As global health has increasingly become a funding priority for governments and aid organizations, participation in international development (by academic surgeons) has been stimulated (and challenged).

Self-reported Determinants of Access to Surgical Care in 3 Developing Countries

PURPOSE Surgical services for children are often absent in resource-limited settings. Identifying the prevalence of surgical disease at the community level is important for developing evidence-based pediatric surgical services and training. We hypothesize that the untreated surgical conditions in the pediatric population are largely uncharacterized and that such burden is significant and poorly understood. Furthermore, no such data exist at the population level to describe this population. METHODS We conducted a nationwide cross-sectional cluster-based population survey to estimate the magnitude of surgical disease in Rwanda. Conducted as a verbal questionnaire, questions included representative congenital, acquired, malignant and injury-related conditions. Pediatric responses were analyzed using descriptive statistics and univariate analysis. RESULTS A total of 1626 households (3175 individuals) were sampled with a 99% response rate; 51.1% of all individuals surveyed were younger than age 18. An estimated 50.5% of the total current surgical need occurs in children. Of all Rwandan children, 6.3% (95% CI 5.4%-7.4%), an estimated 341,164 individuals, were identified to have a potentially treatable surgical condition at the time of the interview. The geographic distribution of surgical conditions significantly differed between adults and children (p<0.001). CONCLUSIONS The results emphasize the magnitude of the pediatric surgery need as well as the need for improved education and resources. This may be useful in developing a collaborative local training program.

Burn management in sub-Saharan Africa: opportunities for implementation of dedicated training and development of specialty centers.

BACKGROUND Vancomycin is considered the drug of choice for methicillin-resistant Staphylococcus aureus infection; however, it has also been linked with nephrotoxicity in the past, sometimes leading to its substitution with linezolid. We hypothesized that patients treated with vancomycin for gram-positive (GP) infections would have an increased incidence of rise in creatinine and need for hemodialysis (HD) compared with patients receiving linezolid. METHODS This was a retrospective cohort study of a prospectively maintained database of all surgical patients treated with either vancomycin or linezolid for GP infections in a single intensive care unit from 2001 to 2008 and managed under a cycling antibiotic protocol. Patients were followed up until hospital discharge. Categorical and continuous variables were evaluated. Multivariable logistic regression was performed. RESULTS A total of 545 patients were treated for 1,046 GP infections (571 with vancomycin, 475 with linezolid) over 7 years. Patient demographics were similar between groups; however, the vancomycin group was associated with a longer treatment course (16.2 [0.5] days vs. 14.3 [0.5] days; p = 0.022). Unadjusted outcomes were similar between groups. Multivariable analysis revealed that Acute Physiology and Chronic Health Evaluation II score predicted an increase in creatinine levels greater than 1.0 following antibiotic therapy (relative risk [RR], 3.01; 95% confidence interval [CI], 1.22–7.42) and subsequent need for HD (RR, 3.07; 95% CI, 1.23–7.62). In addition, initial creatinine level predicted an increase in creatinine levels greater than 1.0 following antibiotic therapy (RR, 4.36; 95% CI, 1.46–12.99) and subsequent need for HD (RR, 10.83; 95% CI, 3.19–36.77). Linezolid was found to be protective regarding rise in creatinine levels greater than 1.0 following antibiotic therapy; however, this was only experienced when vancomycin trough levels greater than 20 were encountered (RR, 5.4;95% CI, 1.19–24.51). CONCLUSION These data suggest that vancomycin is minimally nephrotoxic and has a similar nephrotoxic profile as compared with linezolid when appropriate dosing is used, even among critically ill patients with complex infections. LEVEL OF EVIDENCE Therapeutic/care management, level II.

Pediatric chest II: Benign tumors and cysts.

IMPORTANCE Surgical care is recognized as a growing component of global public health. OBJECTIVE To assess self-reported barriers to access of surgical care in Sierra Leone, Rwanda, and Nepal using the validated Surgeons OverSeas Assessment of Surgical Need tool. DESIGN, SETTING, AND PARTICIPANTS Data for this cross-sectional, cluster-based population survey were collected from households in Rwanda (October 2011), Sierra Leone (January 2012), and Nepal (May and June 2014) using the Surgeons OverSeas Assessment of Surgical Need tool. MAIN OUTCOMES AND MEASURES Basic demographic information, cost and mode of transportation to health care facilities, and barriers to access to surgical care of persons dying within the past year were analyzed. RESULTS A total of 4822 households were surveyed in Nepal, Rwanda, and Sierra Leone. Primary health care facilities were commonly reached rapidly by foot (>70%), transportation to secondary facilities differed by country, and public transportation was ubiquitously required for access to a tertiary care facility (46%-82% of respondents). Reasons for not seeking surgical care when needed included no money for health care (Sierra Leone: n = 103; 55%), a person dying before health care could be arranged (all countries: 32%-43%), no health care facility available (Nepal: n = 11; 42%), and a lack of trust in health care (Rwanda: n = 6; 26%). CONCLUSIONS AND RELEVANCE Self-reported determinants of access to surgical care vary widely among Sierra Leone, Rwanda, and Nepal, although commonalities exist. Understanding the epidemiology of barriers to surgical care is essential to effectively provide surgical service as a public health commodity in developing countries.
