A comparison of outcome measures used to report clubfoot treatment with the Ponseti method: results from a cohort in Harare, Zimbabwe.

There are various established scoring systems to assess the outcome of clubfoot treatment after correction with the Ponseti method. We used five measures to compare the results in a cohort of children followed up for between 3.5 to 5 years.

In January 2017 two experienced physiotherapists assessed children who had started treatment between 2011 and 2013 in one clinic in Harare, Zimbabwe. The length of time in treatment was documented. The Roye score, Bangla clubfoot assessment tool, the Assessing Clubfoot Treatment (ACT) tool, proportion of relapsed and of plantigrade feet were used to assess the outcome of treatment in the cohort. Inter-observer variation was calculated for the two physiotherapists. A comparative analysis of the entire cohort, the children who had completed casting and the children who completed more than two years of bracing was undertaken. Diagnostic accuracy was calculated for the five measures and compared to full clinical assessment (gold standard) and whether referral for further intervention was required for re-casting or surgical review.

31% (68/218) of the cohort attended for examination and were assessed. Of the children who were assessed, 24 (35%) had attended clinic reviews for 4-5 years, and 30 (44%) for less than 2 years. There was good inter-observer agreement between the two expert physiotherapists on all assessment tools. Overall success of treatment varied between 56 and 93% using the different outcome measures. The relapse assessment had the highest unnecessary referrals (19.1%), and the Roye score the highest proportion of missed referrals (22.7%). The ACT and Bangla score missed the fewest number of referrals (7.4%). The Bangla score demonstrated 79.2% (95%CI: 57.8-92.9%) sensitivity and 79.5% (95%CI: 64.7-90.2%) specificity and the ACT score had 79.2% (95%CI: 57.8-92.9%) sensitivity and 100% (95%CI: 92-100%) specificity in predicting the need for referral.

At three to five years of follow up, the Ponseti method has a good success rate that improves if the child has completed casting and at least two years of bracing. The ACT score demonstrates good diagnostic accuracy for the need for referral for further intervention (specialist opinion or further casting). All tools demonstrated good reliability.

Universal Access to Surgical Care and Sustainable Development in Sub-Saharan Africa: A Case for Surgical Systems Research

National level experiences, lessons learnt from the Millennium Development Goal (MDG) era coupled with the academic evidence and proposals generated by the Lancet Commission on Global Surgery (LCoGS) together with the economic arguments and recommendations from the World Bank Group’s “Essential Surgery” Disease Control Priorities (DCP3) publication, provided the impetus for political commitments to improve surgical care capacity at the primary level of the healthcare system in low- and middle-income countries (LMICs) as part of their drive towards universal health coverage (UHC) in the form of World Health Organization (WHO) Resolution A68.15.

This global commitment from governments must be followed up with development of a Global Action Plan and a global coordination mechanism supported by regional implementation frameworks on the part of the WHO in order for the organisation to better coordinate all stakeholders and sustain the technical support needed to develop and implement national surgical health policy in the form of National Surgical Obstetric and Anaesthesia Plans (NSOAPs). As expounded by Gajewski et al, data and research output on surgical care is essential to informing policy development and programme implementation. This area still remains a challenge in sub-Saharan Africa (SSA) but it is envisaged that countries will include this key component in their ongoing national surgical healthcare policy development and programme implementation. In the Zambian case study, research in the area of Global Surgery investment-the surgical workforce scale-up is used to demonstrate the important role of implementation research in the development and implementation of the Zambian NSOAP as well as the need for international collaborations to this end. Scale-up reviews informed by implementation research to evaluate progress on the commitments contained in Resolution A68.15 and Decision A70.22 are essential to sustain the momentum and to help maintain focus on the gaps in all countries. There are opportunities for non-state actors especially local sub-regional academic institutions, non-governmental organizations (NGOs) and private sector to play a key role in surgical healthcare policy development and implementation research. Collection of and better information management of standardised surgical care indicators is essential for such research, for bi-annual WHO progress reporting and for demonstration of impact to justify and encourage further investments in surgical care.

Pediatric Appendicitis Severity in KwaZulu-Natal, South Africa: A Retrospective Cohort Analysis

Acute appendicitis is a common pediatric surgical emergency; however, there are few grading systems to assign disease severity. The American Association for the Surgery of Trauma (AAST) recently developed a grading system for a variety of emergency surgical conditions, including appendicitis. The severity of acute appendicitis in younger patients in KwaZulu-Natal (South Africa) is unknown. We aimed to describe the disease severity in this patient population using the AAST grading system hypothesizing that the AAST grade would correlate with morbidity, management type, and duration of stay.
Single institutional review of patients <18 years old with a final diagnosis of acute appendicitis during 2010-2016 in KwaZulu-Natal, South Africa, was performed. Demographics, physiologic and symptom data, procedural details, postoperative complications, and Clavien-Dindo classification were abstracted. AAST grades were generated based on intraoperative findings. Summary, univariate, and nominal logistic regression analyses were performed to compare AAST grade and outcomes.
A total of 401 patients were identified with median [IQR] age of 11 [5-13], 65% male. Appendectomy was performed in all patients; 2.4% laparoscopic, 37.6% limited incision, and 60% midline laparotomy. Complications occurred in 41.6%, most commonly unplanned relaparotomy (22.4%), surgical site infection (8.9%), pneumonia (7.2%), and acute renal failure (2.9%). Complication rate and median length of stay increased with greater AAST grade (all p < 0.001). AAST grade was independently associated with increased risk of complications.
Pediatric appendicitis is a morbid disease in a developing middle-income country. The AAST grading system is generalizable and accurately corresponds with management strategies as well as key clinical outcomes.

Adult liver transplantation in Johannesburg, South Africa (2004 – 2016): Balancing good outcomes, constrained resources and limited donors

Background. Liver transplantation is the standard of care for the treatment of liver failure worldwide, yet millions of people living in sub-Saharan Africa remain without access to these services. South Africa (SA) has two liver transplant centres, one in Cape Town and the other in Johannesburg, where Wits Donald Gordon Medical Centre (WDGMC) started an adult liver transplant programme in 2004.

Objectives. To describe the outcomes of the adult liver transplant programme at WDGMC.

Methods. This was a retrospective review of all adult orthotopic liver transplants performed at WDGMC from 16 August 2004 to 30 June 2016 with a minimum follow-up of 6 months. The primary outcome was recipient and graft survival and the effect of covariates on survival. Kaplan-Meier survival analysis included all adults who underwent their first transplant for end-stage liver disease (ESLD) (N=275). Proportional hazards regression analysis using hazard ratios (HRs) was conducted to determine which covariates were associated with a significantly increased risk of mortality.

Results. A total of 297 deceased-donor liver transplants were performed during the study period; 19/297 (6.4%) were for acute liver failure (ALF) and the remainder were for ESLD. The median age of recipients was 51 years (interquartile range 41 – 59), and two-thirds were male. The most common cause of ESLD was primary sclerosing cholangitis. The median follow-up was 3.2 years, and recipient survival was characterised in the following intervals: 90 days = 87.6% (95% confidence interval (CI) 83.1 – 91.0), 1 year = 81.7% (95% CI 76.6 – 85.8), and 5 years = 71.0% (95% CI 64.5 – 76.5). Allograft survival was similar: 90 days = 85.8% (95% CI 81.1 – 89.4), 1 year = 81.0% (95% CI 75.8 – 85.2), and 5 years = 69.1% (95% CI 62.6 – 74.7). The most significant covariates that impacted on mortality were postoperative biliary leaks (HR 2.0 (95% CI 1.05 – 3.80)), recipient age >60 years at time of transplant (HR 2.06 (95% CI 1.06 – 3.99)), theatre time >8 hours (HR 3.13 (95% CI 1.79 – 5.48)), and hepatic artery thrombosis (HR 5.58 (95% CI 3.09 – 10.08)). The most common infectious cause of death was invasive fungal infection.

Conclusions. This study demonstrates that outcomes of the adult orthotopic liver transplant programme at WDGMC are comparable with international transplant centres. Management of biliary complications, early hepatic artery thrombosis and post-transplant infections needs to be improved. Access to liver transplantation services is still extremely limited, but can be improved by addressing the national shortage of deceased donors and establishing a national regulatory body for solid-organ transplantation in SA.

Fellowship exit examination in orthopaedic surgery in the commonwealth countries of Australia, UK, South Africa and Canada. Are they comparable and equivalent? A perspective on the requirements for medical migration

nternational migration of healthcare professionals has increased substantially in recent decades. In order to practice medicine in the recipient country, International Medical Graduates (IMG) are required to fulfil the requirements of their new countries medical registration authorities. The purpose of this project was to compare the final fellowship exit examination in Orthopaedic Surgery for the UK, Australia, Canada and South Africa. The curriculum of the Australian Orthopaedic Association (SET) was selected as a baseline reference. The competencies and technical modules specified in the training syllabus, as well as the specifics of the final fellowship examination as outlined in SET, were then compared between countries. Of the nine competencies outlined in SET, the curricula of the UK, South Africa and Canada were all compatible with the Australian syllabus, and covered 97.7%, 86% and 93%, respectively, of all competencies and sub-items. The final fellowship examinations of Australia, South Africa and the UK were all highly similar in format and content. The examination in Canada was substantially different, and had two written sessions but combined the oral and clinical component into a structured OSCE using standardized patients and the component included unmanned stations. There were no significant differences for completion certificate of training and/or board certification observed between these countries. The results of this study strongly suggest that core and technical competencies outlined in the training and education curriculum and the final fellowship examination in Orthopaedic Surgery in Australia, South Africa and the UK are compatible. Between country reciprocal recognition of these fellowship examinations should not only be considered by the relevant Colleges, but should also be regulated by the individual countries health practitioner registration boards and governing bodies.

Demand and capacity to integrate pelvic organ prolapse and genital fistula services in low-resource settings.

There is a need for expanded access to safe surgical care in low- and middle-income countries (LMICs) as illustrated by the report of the 2015 Lancet Commission on Global Surgery. Packages of closely-related surgical procedures may create platforms of capacity that maximize impact in LMIC. Pelvic organ prolapse (POP) and genital fistula care provide an example. Although POP affects many more women in LMICs than fistula, donor support for fistula treatment in LMICs has been underway for decades, whereas treatment for POP is usually limited to hysterectomy-based surgical treatment, occurring with little to no donor support. This capacity-building discrepancy has resulted in POP care that is often non-adherent to international standards and in non-integration of POP and fistula services, despite clear areas of similarity and overlap. The objective of this study was to assess the feasibility and potential value of integrating POP services at fistula centers.

Fistula repair sites supported by the Fistula Care Plus project were surveyed on current demand for and capacity to provide POP, in addition to perceptions about integrating POP and fistula repair services.

Respondents from 26 hospitals in sub-Saharan Africa and South Asia completed the survey. Most fistula centers (92%) reported demand for POP services, but many cannot meet this demand. Responses indicated a wide variation in assessment and grading practices for POP; approaches to lower urinary tract symptom evaluation; and surgical skills with regard to compartment-based POP, and urinary and rectal incontinence. Fistula surgeons identified integration synergies but also potential conflicts.

Integration of genital fistula and POP services may enhance the quality of POP care while increasing the sustainability of fistula care.

Cardiovascular Risk Assessment in Angolan Adults: A Descriptive Analysis from CardioBengo, a Community-Based Survey.

From a community-based survey conducted in Angola, 468 individuals aged 40 to 64 years and not using drug therapy were evaluated according to the World Health Organisation STEPwise Approach to Chronic Disease Risk Factor Surveillance. Using data from tobacco use, blood pressure, blood glucose, and total cholesterol levels, we estimated the 10-year risk of a fatal or nonfatal major cardiovascular event and computed the proportion of untreated participants eligible for pharmacological treatment according to clinical values alone and total cardiovascular risk. The large majority of participants were classified as having a low (<10%) 10-year cardiovascular risk (87.6%), with only 4.5% having a high (≥ 20%) cardiovascular risk. If we consider the single criteria for hypertension, 48.7% of the population should be considered for treatment. This value decreases to 22.0% if we apply the risk prediction chart. The use of hypoglycaemic drugs does not present any differences (19.0% in both situations). The use of lipid-lowering drugs (3.8%) is only recommended by the risk prediction chart. This study reveals the need of integrated approaches for the treatment of cardiovascular disorders in this population. Risk prediction charts can be used as a way to promote a better use of limited resources.

Diagnosis and management of 365 ureteric injuries following obstetric and gynecologic surgery in resource-limited settings.

Ureteric injuries are among the most serious complications of pelvic surgery. The incidence in low-resource settings is not well documented.This retrospective review analyzes a cohort of 365 ureteric injuries with ureterovaginal fistulas in 353 women following obstetric and gynecologic operations in 11 countries in Africa and Asia, all low-resource settings. The patients with ureteric injury were stratified into three groups according to the initial surgery: (a) obstetric operations, (b) gynecologic operations, and (c) vesicovaginal fistula (VVF) repairs.The 365 ureteric injuries in this series comprise 246 (67.4%) after obstetric procedures, 65 (17.8%) after gynecologic procedures, and 54 (14.8%) after repair of obstetric fistulas. Demographic characteristics show clear differences between women with iatrogenic injuries and women with obstetric fistulas. The study describes abdominal ureter reimplantation and other treatment procedures. Overall surgical results were good: 92.9% of women were cured (326/351), 5.4% were healed with some residual incontinence (19/351), and six failed (1.7%).Ureteric injuries after obstetric and gynecologic operations are not uncommon. Unlike in high-resource contexts, in low-resource settings obstetric procedures are most often associated with urogenital fistula. Despite resource limitations, diagnosis and treatment of ureteric injuries is possible, with good success rates. Training must emphasize optimal surgical techniques and different approaches to assisted vaginal delivery.

Essential fracture and orthopaedic equipment lists in low resource settings in Africa.

Low/middle-income countries (LMICs) have a growing need for trauma and orthopaedic (T&O) surgical interventions but lack surgical resources. Part of this is due to the high amount of road traffic accidents in LMICs. We aimed to develop recommendations for an essential list of equipment for three different levels of care providers.The Delphi method was used to achieve consensus on essential and desirable T&O equipment for LMICs. Twenty experts with T&O experience from LMICs underwent two rounds of questionnaires. Feedback was given after each round of questionnaires. The first round of questionnaire consisted of 45 items graded on a Likert scale with the second round consisting of 50 items. We used an electronic questionnaire to collect our data for three different levels of care: non-operative-based provider, specialist provider with operative fracture care and tertiary provider with operative fracture care and orthopaedics.After two rounds of questionnaires, recommendations for each level of care in LMICs included 4 essential equipment items for non-operative-based providers; 27 essential equipment items for specialist providers with operative fracture care and 46 essential equipment items for tertiary providers with operative fracture care and orthopaedic care.These recommendations can facilitate in planning of appropriate equipment required in an institution which in turn has the potential to improve the capacity and quality of T&O care in LMICs. The essential equipment lists provided here can help direct where funding for equipment should be targeted. Our recommendations can help with planning and organising national T&O care in LMICs to achieve appropriate capacity at all relevant levels of care.

Maternal and perinatal adverse outcomes in women with pre-eclampsia cared for at facility-level in South Africa: a prospective cohort study.

Hypertensive disorders of pregnancy contribute to 14% of all maternal deaths, the majority of which occur in low- and middle-income countries. The aim of the study was to describe the maternal and perinatal clinical outcomes of women with pre-eclampsia living in middle- and low-income countries.The study was a prospective observational study of women with pre-eclampsia (n = 1547, 42 twin pregnancies) at three South African tertiary facilities. Using stepwise logistic regression model area under the receiver operating characteristic curve (AUROC) values, the association between maternal baseline and admission characteristics and risk of adverse outcomes was evaluated. Main outcome measures were eclampsia, kidney injury and perinatal death.In 1547 women with pre-eclampsia, 16 (1%) died, 147 (9.5%) had eclampsia, four (0.3%) had a stroke and 272 (17.6%) had kidney injury. Of the 1589 births, there were 332 (21.0%) perinatal deaths; of these, 281 (84.5%) were stillbirths. Of 1308 live births, 913 (70.0%) delivered <37 completed weeks and 544 (41.7%) delivered <34 weeks' gestation. Young maternal age (AUROC = 0.76, 95% confidence interval (CI) = 0.71-0.80) and low Body Mass Index BMI (AUROC 0.65, 95% CI = 0.59-0.69) were significant predictors of eclampsia. Highest systolic blood pressure had the strongest association with kidney injury, (AUROC = 0.64, 95% CI = 0.60-0.68). Early gestation at admission was most strongly associated with perinatal death (AUROC = 0.81, 95% CI = 0.77-0.84).The incidence of pre-eclampsia complications, perinatal death and preterm delivery in women referred to tertiary care in South Africa was much higher than reported in other low- and middle-income studies and despite access to tertiary care interventions. Teenage mothers and those with low BMI were at highest risk of eclampsia. This information could be used to inform guidelines, the research agenda and policy.
