Cost-Effectiveness of Two Government District Hospitals in Sub-Saharan Africa

Background

District hospitals in sub-Saharan Africa are in need of investment if countries are going to progress towards universal health coverage, and meet the sustainable development goals and the Lancet Commission on Global Surgery time-bound targets for 2030. Previous studies have suggested that government hospitals are likely to be highly cost-effective and therefore worthy of investment.

Methods

A retrospective analysis of the inpatient logbooks for two government district hospitals in two sub-Saharan African hospitals was performed. Data were extracted and DALYs were calculated based on the diagnosis and procedures undertaken. Estimated costs were obtained based on the patient receiving ideal treatment for their condition rather than actual treatment received.

Results

Total cost per DALY averted was 26 (range 17–66) for Thyolo District Hospital in Malawi and 363 (range 187–881) for Bo District Hospital in Sierra Leone.

Conclusion

This is the first published paper to support the hypothesis that government district hospitals are very cost-effective. The results are within the same range of the US$32.78–223 per DALY averted published for non-governmental hospitals.

     

The Current Status of International Partnerships for Child Surgery in Sub-Saharan Africa

Disparity still exists in the surgical care between sub-Saharan Africa and developed countries. Several international initiatives have been undertaken in the past decades to address the disparity. This study looks at the impact of these programs in child surgery in Sub-Saharan Africa. Review of electronic databases Medline and African Index Medicus on international partnerships for child surgery in Sub-Saharan Africa was undertaken. Four types of international initiatives were identified and consist of periodic medical missions; partnerships between foreign medical institutions or charities and local institutions; international health electives by surgical residents; and training of individual surgeons from developing countries in foreign institutions. The results of these efforts were variable, but sustainability and self-reliance of host nations were limited. Sociocultural factors, dearth of facilities, and lack of local governments'' commitment were main impediments to effective local development or transfer of modern protocols of surgical management and improvement of pediatric surgical care at the host community level. Current initiatives may need improvements with better understanding of the sociocultural dynamics and local politics of the host nation, and improved host nation involvement and commitment. This may engender development of locally controlled viable services and sustainable high level of care.Key words: Partnership, Medical mission, Child surgery, Africa, Developing countryDuring the last three decades of the 20th century, significant efforts were undertaken to reduce child morbidity and mortality globally and more especially in developing countries.¹ In Sub-Saharan Africa, the traditional focus of global health in this regard was control of infectious diseases, nutritional support, malaria controls, and lately, HIV/AIDS control.¹ Recently, however, the surgical needs of the pediatric population in developing countries have received attention.² Emerging evidence demonstrates that childhood surgical conditions are a significant public health care problem in Sub-Saharan Africa, and hence the need to consider them as an essential component of child health programs.^3,4 Despite this recognition and increasing globalization, child surgery in Sub-Saharan Africa is still challenged by ignorance, delayed diagnosis, limited diagnostic and support facilities, critical shortage of surgeons and trained personnel, poor access to surgical care, and inadequate governmental support.^1,3,5 As a result of these disadvantages, substantial disparity exists in the surgical care and outcome in this setting and the developed countries.^1,4,6 To address this discrepancy and elevate the level of child surgery standards in some of these countries, strong efforts have been expended over the past decades through a variety of international partnership programs.^6–11 Some of these programs have been published in medical literature, but a review of the programs is rarely reported.This review evaluates the programs in Sub-Saharan Africa that have been published in Medline, African Index Medicus, and the African Journals Online. The focus is on the types, outcome, challenges, and recommendations to improve the impact in the host communities.     

Rural Surgery in Niger: A Multicentric Study in 21 District Hospitals

The purpose of the study was to evaluate the qualitative aspect and global impact of surgery in a district hospital (DH) since the launching of the surgery at the district level. Surgical care was provided by general practitioners (GP) who received 12-month training in surgery, certified by a “Capacity of District Surgery” (CDS) diploma. It was a prospective study during 4 years from 2007 to 2010. Of the 34 DHs, only 21 were functional and included in this study. Most of the DHs had two or more CDS (n?=?15). The majority of the DHs had one nurse surgical aid (n?=?16) and one nurse anesthetist (n?=?17). The total number of surgical operations was 18,441 cases; emergency cases represented 51.8 % and elective surgery 48.2 %. Regarding emergency surgery, cesarean sections revealed the most common surgical procedure (37.21 %), followed by wound debridement (19.42 %). In elective surgery, hernia repair and hydrocelectomy were the most common surgical procedures (69.60 %), followed by gynecologic procedures in 12.74 % of the cases. The global complication rate was 4.34 %. The global mortality rate was 1.04 % (n?=?192), 102 deaths following cesarean section (2.87 %). No death was encountered in elective surgery. Nine hundred and fifty-five patients (5.17 %) were transferred to a higher-level facility of whom 598 patients (62.61 %) were admitted for fracture treatment. The concept of district surgery has proven to be an effective tool to counter skilled medical manpower shortage to perform emergency and elective basic surgery at the rural level and could be adopted by developing countries facing similar health challenges.     

Anesthesia in French-speaking Sub-Saharan Africa: an overview

The situation of Anesthesiology in Sub-Saharan Africa is unique in that nowhere else in the world has the absolute numbers of anesthesiologists decreased during the nineties. Most anesthesia services to the populations of these 17 poor countries are provided by nurse-anesthetists, either certified or trained on the job. Their mean age often exceeds 40, which leads to expect an acute shortage within fifteen years. Experienced anesthesiologists are now so few that, in most countries, the critical mass of knowledgeable specialists no longer exists to train new anesthesia professionals. This summary of local surveys provides a brief overview of current workforce, institutions, drugs and material constituting the daily environment of our colleagues. Challenges are outlined, with special emphasis on brain drain. Solutions are proposed, underlining the promising role of a few anesthesia schools, the need for young anesthesiologists to enter teaching, and the expectations they are supposed to meet.     

Histological Alterations Following Bariatric Surgery: Pilot Study

Background  Macroscopic clinical evidence of tissue damaging following bariatric surgery pushed plastic surgeons to presume microscopic alterations as well. Methods  Five preliminary cases studied randomly, and compared with healthy tissues, confirmed these initial suspects. A deeper and wider study has then been structured. Results  Preliminary results are so evident to encourage us to carry on an estimated 2–3 years multidisciplinary study. Conclusions  What we want to study is if histological post-bariatric alterations are confirmed, and if these can be considered responsible for higher complication rate in body contouring following bariatric surgery.     

Intraoperative Ultrasound with Contrast Medium in Resective Pancreatic Surgery: A Pilot Study

Background  

The introduction of contrast-enhanced ultrasound has been a major innovation in liver and pancreatic imaging. Previous studies have validated its intraoperative use during liver surgery, while there is a lack of data regarding its use during pancreatic surgery. The purpose of the present study was to prospectively evaluate the possible role of contrast-enhanced intraoperative ultrasound (CEIOUS) during resective pancreatic surgery for primary lesion characterization and intraoperative staging.     

Clinical Management of Solitary Pulmonary Micronodule: A Pilot Study

BackgroundSolitary pulmonary micronodules (SPMN) characteristically have a diameter of 0.1–0.5 cm.ObjectiveThe aim of this prospective study is to evaluate the surgical approach to SPMN in order to establish the most appropriate treatment.MethodsBetween January 2007 and June 2011, 146 SPMN patients (94 males and 52 females) were prospectively evaluated. Patients were divided into two groups based on history of malignancy (Group A, 59 patients) and generic risk factors for lung cancer (Group B, 87 patients). After gathering patient information, we proposed surgery or thin-section computed tomography (TSCT) follow-up to both Groups.ResultsPreference for surgery versus TSCT follow-up was 90% versus 10% in Group A and 78% versus 22% in Group B, respectively. In Group A, we discovered 46 metastases from previous cancer (78%), 8 primary lung cancers (14%) and 5 benign lesions (8%). In Group B, we found 5 metastases (6%), 13 non-small-cell lung cancer (15%) and 69 benign lesions (79%). Statistical analysis revealed a high positive predictive value (PPV=0.9) between total surgical patients versus TSCT follow-up patients.ConclusionsThe indication for surgery in solitary pulmonary micronodules is aimed at establishing early diagnosis and curing malignant disease. Our study indicates that in patients with previous cancer, surgery is essential. In patients with generic risk for lung cancer, surgical indications should be contemplated more carefully, even though the pulmonary malignancy rate of 21% in Group B seems to indicate the advisability of surgery.     

The Effect of a Surgery Residency Program and Enhanced Educational Activities on Trauma Mortality in Sub-Saharan Africa

Introduction

To address the need for more surgical providers in low-resource settings, a collaboration to create a surgical residency-training program for local Malawian physicians was established in 2009. This study sought to describe the short-term independent effect of a surgical residency program on trauma mortality at a tertiary trauma center in sub-Saharan Africa.

Methods

We conducted a retrospective analysis of all patients recorded in the trauma surveillance registry of Kamuzu Central Hospital in Lilongwe, Malawi, from 2009 (three residents) through 2014 (11 residents). Log-binominal regression modeling was used to compare the risk ratio of death compared to the referent year of 2009, when the program was started, after adjusting for relevant covariates. Primary injury type was used as a surrogate for injury severity.

Results

In total, 82,534 patients were recorded into the KCH Trauma Registry during the study period. Mean age was 23.1 years (SD 15.7) with a male preponderance (72.1%). Trauma patient volume increased from 8725 patients in 2009 to 15,998 patients in 2014. Each year had a significantly decreased risk of death compared to 2009 when adjusted for primary injury type, age, and gender, with an adjusted risk ratio of 0.73 (95% CI 0.58, 0.90) in 2010 and 0.52 (95% CI 0.43, 0.62) in 2014.

Conclusion

The global burden of surgical diseases cannot be attenuated in the presence of an inadequate surgical workforce. After institution of a surgery residency program, adjusted injury-associated mortality decreased each year despite substantial increases in trauma patient volume. In low-resource settings, establishment of a surgical residency program significantly improves trauma-associated outcomes.

     

Intentional injury against children in Sub-Saharan Africa: A tertiary trauma centre experience

BackgroundIntentional injuries are the result of violence. This is an important public health issue, particularly in children, and is an unaddressed problem in sub-Saharan Africa. This study sought to describe the characteristics of intentional injury, particularly physical abuse, in children presenting to our tertiary trauma centre in Lilongwe, Malawi and how they compare to children with unintentional injuries.MethodsA retrospective analysis of children (<18 years old) with traumatic injuries presenting to Kamuzu Central Hospital (KCH) in Lilongwe, Malawi from 2009 to 2013 was performed. Children with intentional and unintentional injuries were compared with bivariate analysis and multivariate logistic regression modelling.Results67,672 patients with traumatic injuries presented to KCH of which 24,365 were children. 1976 (8.1%) patients presented with intentional injury. Intentional injury patients had a higher mean age (11.1 ± 5.0 vs. 7.1 ± 4.6, p < 0.001), a greater male preponderance (72.5 vs. 63.6%, p < 0.001), were more often injured at night (38.3 vs. 20.7%, p < 0.001), and alcohol was more often involved (7.8 vs. 1.0%, p < 0.001). Multivariate logistic regression modelling showed that increasing age, male gender, and nighttime or urban setting for injury were associated with increased odds of intentional injury. Soft tissue injuries were more common in intentional injury patients (80.5 vs. 45.4%, p < 0.001) and fist punches were the most common weapon (25.6%). Most patients were discharged in both groups (89.2 vs 80.9%, p < 0.001) and overall mortality was lower for intentional injury patients (0.9 vs. 1.2%, p = 0.001). Head injury was the most common cause of death (43.8 vs. 32.2%, p < 0.001) in both groups.ConclusionsSub-Saharan African tertiary hospitals are uniquely positioned to play a pivotal role in the identification, clinical management, and alleviation of intentional injuries to children by facilitating access to social services and through prevention efforts.     

Analysis of Prospective Trauma Registry Data in Francophone Africa: A Pilot Study from Cameroon

Introduction

Injury rates in sub-Saharan Africa are among the highest in the world, but prospective, registry-based reports from Cameroon are limited. We aimed to create a prospective trauma registry to expand the data elements collected on injury at a busy tertiary center in Yaoundé Cameroon.

Methods

Details of the injury context, presentation, care, cost, and disposition from the emergency department (ED) were gathered over a 6-month period, by trained research assistants using a structured questionnaire. Bivariate and multivariate models were built to explore variable relationships and outcomes.

Results

There were 2,855 injured patients in 6 months, comprising almost half of all ED visits. Mean age was 30 years; 73 % were male. Injury mechanism was road traffic injury in 59 %, fall in 7 %, penetrating trauma in 6 %, and animal bites in 4 %. Of these, 1,974 (69 %) were discharged home, 517 (18 %) taken to the operating room, and 14 (1 %) to the intensive care unit. The body areas most severely injured were pelvis and extremity in 43 %, head in 30 %, chest in 4 %, and abdomen in 3 %. The estimated injury severity score (eISS) was <9 in 60 %, 9–24 in 35 %, and >25 in 2 %. Mortality was 0.7 %. In the multivariate analysis, independent predictors of mortality were eISS ≥9 and Glasgow Coma Score ≤12. Road traffic injury was an independent predictor for the need to have surgery. Trauma registry results were presented to the Ministry of Health in Cameroon, prompting the formation of a National Injury Committee.

Conclusions

Injuries comprise a significant proportion of ED visits and utilization of surgical services in Yaoundé. A prospective approach allows for more extensive information. Thorough data from a prospective trauma registry can be used successfully to advocate for policy towards prevention and treatment of injuries.

     

State of Surgery in Tropical Africa: A Review

This is a review of recently published literature on surgery in tropical Africa. It presents the current state of surgical need and surgical practice on the continent. We discuss the enormous burden of surgical pathology (as far as it is known) and the access to and acceptability of surgery. We also describe the available facilities in terms of equipment and manpower. The study looked at the effects of the human immunodeficiency virus, the role of traditional healers, anesthesia, and the economics of surgery. Medical training and research are discussed, as are medical migration out of Africa and the concept of task shifting, where surgical procedures are performed by others when surgeons are not available. It closes with recommendations for involvement and action in this area of great global need.

Partnership for Sustainability in Cardiac Surgery to Address Critical Rheumatic Heart Disease in Sub-Saharan Africa: The Experience from Rwanda

Importance

Rheumatic heart disease (RHD) in the developing world results in critical disability among children, adolescents, and young adults—marginalizing a key population at its peak age of productivity. Few regions in sub-Saharan Africa have independently created an effective strategy to detect and treat streptococcal infection and mitigate its progression to RHD.

Objective

We describe a unique collaboration, where the Rwanda Ministry of Health, the Rwanda Heart Foundation, and an expatriate humanitarian cardiac surgery program have together leveraged an innovative partnership as a means to expand Rwanda’s current capacity to address screening and primary prevention, as well as provide life-saving cardiac surgery for patients with critical RHD.

Evidence review

Interviews with key personnel and review of administrative records were conducted to obtain qualitative and quantitative data on the recruitment of clinical personnel, procurement of equipment, and program finances. The number of surgical cases completed and the resultant clinical outcomes are reviewed.

Findings

From 2008 to 2013, six annual visits were completed. A total of 128 prosthetic valves have been implanted in 86 complex patients in New York Heart Association (NYHA) class III or IV heart failure, with excellent clinical outcomes (5 % 30-day mortality). Postoperative complications included a cerebrovascular accident (n = 1) and hemorrhage, requiring reoperation (n = 2). All procedures were performed with participation of local personnel.

Conclusions and relevance

This strategy provides a reliable and consistent model of sophisticated specialty care delivery; inclusive of patient-centered cardiac surgery, mentorship, didactics, skill transfer, and investment in a sustainable cardiac program to address critical RHD in sub-Saharan Africa.     

Hospital Costs and Severity of Illness in Three Types of Elective Surgery

Background: If patients who are more severely ill have greater hospital costs for surgery, then health-care reimbursements need to be adjusted appropriately so that providers caring for more seriously ill patients are not penalized for incurring higher costs. The authors' goal for this study was to determine if severity of illness, as measured by either the American Society of Anesthesiologists Physical Status (ASA PS) or the comorbidity index developed by Charlson, can predict anesthesia costs, operating room costs, total hospital costs, or length of stay for elective surgery.

Methods: The authors randomly selected 224 inpatients (60% sampling fraction) having either colectomy (n = 30), total knee replacement (n = 100), or laparoscopic cholecystectomy (n = 94) from September 1993 to September 1994. For each surgical procedure, backward-elimination multiple regression was used to build models to predict (1) total hospital costs, (2) operating room costs, (3) anesthesia costs, and (4) length of stay. Explanatory candidate variables included patient age (years), sex, ASA PS, Charlson comorbidity index (which weighs the number and seriousness of coexisting diseases), and type of insurance (Medicare/Medicaid, managed care, or indemnity). These analyses were repeated for the pooled data of all 224 patients. Costs (not patient charges) were obtained from the hospital cost accounting software.

Results: Mean total hospital costs were $3,778 (95% confidence interval +/- 299) for laparoscopic cholecystectomy, $13,614 (95% CI +/- 3,019) for colectomy, and $18,788 (95% CI +/- 573) for knee replacement. The correlation (r) between ASA PS and Charlson comorbidity scores equaled 0.34 (P < .001). No consistent relation was found between hospital costs and either of the two severity-of-illness indices. The Charlson comorbidity index (but not the ASA PS) predicted hospital costs only for knee replacement (P = .003). The ASA PS, but not the Charlson index, predicted operating room and anesthesia costs only for colectomy (P <.03).
