BackgroundThere are large disparities in access to surgical services due to a multitude of factors, including insufficient health human resources, infrastructure, medicines, equipment, financing, logistics, and information reporting. This study aimed to assess these important factors in Uganda’s government hospitals as part of a larger study examining surgical and anesthesia capacity in low-income countries in Africa.MethodsA standardized survey tool was administered via interviews with Ministry of Health officials and key health practitioners at 14 public government hospitals throughout the country. Descriptive statistics were used to analyze the data.ResultsThere were a total of 107 general surgeons, 97 specialty surgeons, 124 obstetricians/gynecologists (OB/GYNs), and 17 anesthesiologists in Uganda, for a rate of one surgeon per 100,000 people. There was 0.2 major operating theater per 100,000 people. Altogether, 53% of all operations were general surgery cases, and 44% were OB/GYN cases. In all, 73% of all operations were performed on an emergency basis. All hospitals reported unreliable supplies of water and electricity. Essential equipment was missing across all hospitals, with no pulse oximeters found at any facilities. A uniform reporting mechanism for outcomes did not exist.ConclusionsThere is a lack of vital human resources and infrastructure to provide adequate, safe surgery at many of the government hospitals in Uganda. A large number of surgical procedures are undertaken despite these austere conditions. Many areas that need policy development and international collaboration are evident. Surgical services need to become a greater priority in health care provision in Uganda as they could promise a significant reduction in morbidity and mortality.

BACKGROUND Surgery has been neglected in low- and middle-income countries for decades. It is vital that the Post-2015 Development Agenda reflect that surgery is an important part of a comprehensive global health care delivery model. We compare the operative capacities of multiple low- and middle-income countries and identify critical gaps in surgical infrastructure. METHODS The Harvard Humanitarian Initiative survey tool was used to assess the operative capacities of 78 government district hospitals in Bangladesh (n = 7), Bolivia (n = 11), Ethiopia (n = 6), Liberia (n = 11), Nicaragua (n = 10), Rwanda (n = 21), and Uganda (n = 12) from 2011 to 2012. Key outcome measures included infrastructure, equipment availability, physician and nonphysician surgical providers, operative volume, and pharmaceutical capacity. RESULTS Seventy of 78 district hospitals performed operations. There was fewer than one surgeon or anesthesiologist per 100,000 catchment population in all countries except Bolivia. There were no physician anesthesiologists in any surveyed hospitals in Rwanda, Liberia, Uganda, or in the majority of hospitals in Ethiopia. Mean annual operations per hospital ranged from 374 in Nicaragua to 3,215 in Bangladesh. Emergency operations and obstetric operations constituted 57.5% and 40% of all operations performed, respectively. Availability of pulse oximetry, essential medicines, and key infrastructure (water, electricity, oxygen) varied widely between and within countries. CONCLUSION The need for operative procedures is not being met by the limited operative capacity in numerous low- and middle-income countries. It is of paramount importance that this gap be addressed by prioritizing essential surgery and safe anesthesia in the Post-2015 Development Agenda.

OBJECTIVE Humanitarian surgery is often organized and delivered with short notice and limited time for developing unique strategies for providing care. While some surgical pathologies can be anticipated by the nature of the crisis, the role of foreign medical teams in treating the existing and unmet burden of surgical disease during crises is unclear. The purpose of this study was to examine published data from crises during the years 1990 through 2011 to understand the role of foreign medical teams in providing surgical care in these settings. METHODS A literature search was completed using PubMed, MEDLINE, and EMBASE databases to locate relevant manuscripts published in peer-reviewed journals. A qualitative review of the surgical activities reported in the studies was performed. RESULTS Of 185 papers where humanitarian surgical care was provided by a foreign medical team, only 11 articles met inclusion criteria. The reporting of surgical activities varied significantly, and pooled statistical analysis was not possible. The quality of reporting was notably poor, and produced neither reliable estimates of the pattern of surgical consultations nor data on the epidemiology of the burden of surgical diseases. The qualitative trend analysis revealed that the most frequent procedures were related to soft tissue or orthopedic surgery. Procedures such as caesarean sections, hernia repairs, and appendectomies also were common. As length of deployment increased, the surgical caseload became more reflective of the existing, unmet burden of surgical disease. CONCLUSIONS This review suggests that where foreign medical teams are indicated and requested, multidisciplinary surgical teams capable of providing a range of emergency and essential surgical, and rehabilitation services are required. Standardization of data collection and reporting tools for surgical care are needed to improve the reporting of surgical epidemiology in crisis-affected populations.

Limb amputations are frequently performed as a result of trauma inflicted during conflict or disasters. As demonstrated during the 2010 earthquake in Haiti, coordinating care of these patients in austere settings is complex. During the 2011 Humanitarian Action Summit, consensus statements were developed for international organizations providing care to limb amputation patients during disasters or humanitarian emergencies. Expanded planning is needed for a multidisciplinary surgical care team, inclusive of surgeons, anesthesiologists, rehabilitation specialists and mental health professionals. Surgical providers should approach amputation using an operative technique that optimizes limb length and prosthetic fitting. Appropriate anesthesia care involves both peri-operative and long-term pain control. Rehabilitation specialists must be involved early in treatment, ideally before amputation, and should educate the surgical team in prosthetic considerations. Mental health specialists must be included to help the patient with community reintegration. A key step in developing local health systems the establishment of surgical outcomes monitoring. Such monitoring can optimizepatient follow-up and foster professional accountability for the treatment of amputation patients in disaster settings and humanitarian emergencies.

The provision of surgery within humanitarian crises is complex, requiring coordination and cooperation among all stakeholders. During the 2011 Humanitarian Action Summit best practice guidelines were proposed to provide greater accountability and standardization in surgical humanitarian relief efforts. Surgical humanitarian relief planning should occur early and include team selection and preparation, appropriate disaster-specific anticipatory planning, needs assessment, and an awareness of local resources and limitations of cross-cultural project management. Accurate medical record keeping and timely follow-up is important for a transient surgical population. Integration with local health systems is essential and will help facilitate longer term surgical health system strengthening.

Abstract: Objective To assess the consistent availability of basic surgical resources at selected facilities in seven countries. Methods In 2010–2014, we used a situational analysis tool to collect data at district and regional hospitals in Bangladesh (n = 14), the Plurinational State of Bolivia (n = 18), Ethiopia (n = 19), Guatemala (n = 20), the Lao Peoples Democratic Republic (n = 12), Liberia (n = 12) and Rwanda (n = 25). Hospital sites were selected by pragmatic sampling. Data were geocoded and then analysed using an online data visualization platform. Each hospital’s catchment population was defined as the people who could reach the hospital via a vehicle trip of no more than two hours. A hospital was only considered to show consistent availability of basic surgical resources if clean water, electricity, essential medications including intravenous fluids and at least one anaesthetic, analgesic and antibiotic, a functional pulse oximeter, a functional sterilizer, oxygen and providers accredited to perform surgery and anaesthesia were always available. Findings Only 41 (34.2%) of the 120 study hospitals met the criteria for the provision of consistent basic surgical services. The combined catchments of the study hospitals in each study country varied between 3.3 million people in Liberia and 151.3 million people in Bangladesh. However, the combined catchments of the study hospitals in each study country that met the criteria for the provision of consistent basic surgical services were substantially smaller and varied between 1.3 million in Liberia and 79.2 million in Bangladesh. Conclusion Many study facilities were deficient in the basic infrastructure necessary for providing basic surgical care on a consistent basis.

Importance Options for managing splenic injuries have evolved with a focus on nonoperative management. Long-term outcomes, such as readmissions and delayed splenectomy rate, are not well understood. Objective To describe the natural history of isolated splenic injuries in the United States and determine whether patterns of readmission were influenced by management strategy. Design, Setting, and Participants The Healthcare Cost and Utilization Project’s Nationwide Readmission Database is an all-payer, all-ages, longitudinal administrative database that provides data on more than 35 million weighted US discharges yearly. The database was used to identify patients with isolated splenic injuries and the procedures that they received. Adult patients with isolated splenic injuries admitted from January 1 through June 30, 2013, and from January 1 through June 30, 2014, were included. Those who died during the index hospitalization or who had an additional nonsplenic injury with an Abbreviated Injury Score of 2 or greater were excluded. Univariate and mixed-effects logistic regression analysis controlling for center effect were used. Weighted numbers are reported. Exposures Initial management strategy at the time of index hospitalization, including nonprocedural management, angioembolization, and splenectomy. Main Outcomes and Measures All-cause 6-month readmission rate. Secondary outcome was delayed splenectomy rate. Results A weighted sample of 3792 patients (2146 men [56.6%] and 1646 women [43.4%]; mean [SE] age, 48.5 [0.7] years) with 5155 admission events was included. During the index hospitalization, 825 (21.8%) underwent splenectomy, 293 (7.7%) underwent angioembolization, and 2673 (70.5%) had no procedure. The overall readmission rate was 21.1% (799 patients). Readmission rates did not differ based on initial management strategy (195 patients undergoing splenectomy [23.6%], 70 undergoing angioembolism [23.9%], and 534 undergoing no procedure [20%]; P = .33). Splenectomy was performed in 36 of 799 readmitted patients (4.5%) who did not have a splenectomy at their index hospitalization, leading to an overall delayed splenectomy rate of 1.2% (36 of 2967 patients). In mixed-effects logistic regression analysis controlling for patient, injury, clinical, and hospital characteristics, the choice of splenectomy (odds ratio, 0.93; 95% CI, 0.66-1.31) vs angioembolization (odds ratio, 1.19; 95% CI, 0.72-1.97) as initial management strategy was not associated with readmission. Conclusions and Relevance This national evaluation of the natural history of isolated splenic injuries from index admission through 6 months found that approximately 1 in 5 patients are readmitted within 6 months of discharge after an isolated splenic injury. However, the chance of readmission for splenectomy after initial nonoperative management was 1.2%. This finding suggests that the current management strategies used for isolated splenic injuries in the United States are well matched to patient need.
