BACKGROUND:Data on colorectal cancer (CRC) diagnosis to treatment interval (DTI), an index of quality assurance in high-income countries (HICs) is lacking in South Africa. This study aimed to determine DTIs and their impact on CRC survival in a South African cohort.METHODS:Participants (n = 289) from the Colorectal Cancer in South Africa (CRCSA) cohort were identified for inclusion. The DTI was defined as the duration between the diagnosis and initial definitive treatment and categorised into approximate quartiles (Q1-4). The DTI quartiles were 0-14 days, 15-28 days, 29-70 days, and ≥ 71 days. Overall survival (OS) was illustrated using the Kaplan-Meier method and compared between DTI groups using Cox proportional hazards (PH) regression.RESULTS:There was no significant impact of the DTI (as quartiles) on overall CRC survival. The median length of time between DTI in this cohort was 29 days. Significant associations were identified between the DTI and self-reported ethnicity (p-value = 0.025), the site of the malignancy (colon vs rectum) (p-value < 0.0001), multidisciplinary team (MDT) review (p-value = 0.015) and the initial treatment modality (p-value < 0.0001).CONCLUSION:Prolonged DTIs did not significantly impact survival for those with CRC in the CRCSA cohort. Symptom to diagnosis time should be investigated as a determinant of survival.

BACKGROUND:As the worldwide demand for specialist surgeons increases, and to complement surgical training provided through governmental institutions, private hospitals are increasingly hosting trainees. Wits Donald Gordon Medical Centre (WDGMC) is a private academic hospital in Johannesburg with a Colorectal Unit (CRU) that hosts several trainees. While published studies demonstrate that the involvement of trainees in surgery does not adversely impact outcomes, private patients' perceptions of the role of trainees in their care have not been as widely researched.METHODS:This was a prospective, cross-sectional study using a self-administered questionnaire hosted on a REDCap database. Statistical analysis was performed using SPSS version 26.RESULTS:One hundred and seventy-four patients participated in the study, and 74.1% of respondents felt that training of doctors should occur in private hospitals in South Africa. Of the sample, 83.3% would allow a supervised trainee to perform a part of their operation, provided they had been made aware of trainee participation in advance (78%). Sixty per cent of patients felt that interaction with a trainee enhanced their care, and 52.3% of patients suggested that seeing more than one doctor a day improved their experience.CONCLUSION:Our results suggest that privately funded patients support the surgical training of medical doctors in private academic training hospitals, and they are willing to be participants in the training process. Moreover, training programmes in this setting appear to enhance the patient experience. We are optimistic that these findings could be used to advocate for expanded training opportunities across the private sector in South Africa.

Pediatric ALF is rare but life-threatening and may require urgent transplantation. In low and middle-income countries, access to transplantation is limited, deceased organ donation rates are low, and data on outcomes scarce. The Wits Donald Gordon Medical Centre, in Johannesburg, is one of only two centers in South Africa that perform pediatric liver transplant. We describe the etiology, clinical presentation, and outcomes of children undergoing liver transplant for ALF at our center over the past 14 years. We performed a retrospective chart review of all children undergoing liver transplantation for ALF from November 2005 to September 2019. Recipient data included demographics, clinical and biochemical characteristics pretransplant, post-operative complications, and survival. We conducted descriptive data analysis and used the Kaplan-Meier method for survival analysis. We performed 182 primary pediatric liver transplants. Of these, 27 (15%) were for ALF, mostly from acute hepatitis A infection (11/27;41%). Just over half of the grafts were from living donors (15/27;56%), and five grafts (5/27;19%) were ABO-incompatible. The most frequent post-transplant complications were biliary leaks (9/27;33%). There were two cases of hepatic artery thrombosis (2/27;7%), one of whom required re-transplantation. Unadjusted patient and graft survival at one and 3 years were the same, at 81% (95% CI 61%-92%) and 78% (95% CI 57%-89%), respectively. At WDGMC, our outcomes for children who undergo liver transplantation for ALF are excellent. We found workable solutions that effectively addressed our pervasive organ shortages without compromising patient outcomes.

In everyday clinical practice, healthcare professionals (HCPs) are exposed to large quantities of confidential patient information, and many use WhatsApp groups to share this information. WhatsApp groups provide efficient mechanisms for clinical management advice, decision-making support and peer review. However, most HCPs do not fully understand the legal and ethical implications of sharing content in a WhatsApp group setting, which is often thought to be hosted on a secure platform and therefore removed from public scrutiny. In our paper, we unpack the legal and ethical issues that arise when information is shared in WhatsApp groups. We demonstrate that sharing content in this forum is tantamount to the publication of content; in other words, those who share content are subject to the same legal ramifications as a journalist would be. We also examine the role of the WhatsApp group administrator, who bears an additional legal burden by default, often unknowingly so. We consider the recommendations made by the Health Professions Council of South Africa in their guidelines for the use of social media, and highlight some areas where we feel the guidelines may not adequately protect HCPs from the legal repercussions of sharing content in a WhatsApp group. Finally, we provide a set of guidelines for WhatsApp group users that should be regularly posted onto the group by the relevant group administrator to mitigate some of the legal liabilities that may arise. We also provide guidelines for group administrators.

BACKGROUNDThe Colorectal Cancer South Africa (CRCSA) study is an observational cohort of patients with colorectal cancer (CRC) in Johannesburg, South Africa (SA). We found that the mean age at the time of CRC diagnosis was 56.6 years, consistent with studies from SA and sub-Saharan Africa. In high-income settings, comorbidity adversely affects CRC survival, and patients are substantially older at the time of CRC diagnosis. Given the younger age at CRC diagnosis in the CRCSA cohort, we hypothesised that comorbidity may be less prevalent and have little impact on CRC survival.OBJECTIVESTo determine the prevalence of comorbidity and whether comorbidity adversely affects overall survival (OS) of CRC patients.METHODSPatients enrolled in the CRCSA study between January 2016 and July 2018 were included. The cohort comprised a convenience sample of adults with histologically confirmed CRC, treated at the University of the Witwatersrand Academic Teaching Hospital Complex. Demographic, clinical and histological variables were collected at baseline and participants were followed up for OS. The Charlson comorbidity index (CCI) scoring system was used to classify participants as 'no comorbidity' (CCI score 0) and '1 or more comorbidities' (CCI score ≥1). A descriptive analysis of the cohort was undertaken, while survival across comorbidity groups was compared by the Kaplan-Meier method and Cox proportional hazards (PH) regression models. Multivariable Cox PH regression was performed to examine the effect of comorbidity on survival (unadjusted) and then adjusted for variables.RESULTSThere were 424 participants, and the mean (standard deviation) age was 56.6 (14.1) years (range 18 - 91). Only 19.1% of participants had ≥1 comorbidities, of which diabetes mellitus was most frequent (12.3%), followed by chronic obstructive pulmonary disease (4.7%) and cardiovascular disease (3.1%). There was no significant difference in unadjusted and adjusted risk of death for the group with ≥1 comorbidities compared with those with no comorbidity. However, an incidental finding showed a significantly increased risk of death for those receiving potentially curative treatment later than 40 days after CRC diagnosis.CONCLUSIONSIn the CRCSA cohort from Johannesburg, comorbidity is uncommon, with no significant adverse effect on OS. If potentially curative treatment is initiated within 40 days of CRC diagnosis, OS could be improved. To fully understand the epidemiology of CRC in SA, population-based registries are essential, and future research should aim to identify health system failures that lead to delays in intervention beyond 40 days in patients with CRC.

Children who undergo liver transplantation and subsequently develop BSI are at risk for adverse outcomes. Research from high‐income settings contrasts the dearth of information from transplant centers in low‐ and middle‐income countries, such as South Africa. Therefore, this study from Johannesburg aimed to describe the clinical and demographic profile of children undergoing liver transplantation, and determine the incidence and pattern of BSI and associated risk factors for BSI during the first year after liver transplant. Pediatric liver transplants performed from 2005 to 2014 were reviewed. Descriptive analyses summarized donor, recipient, and post‐transplant infection characteristics. Association between BSI and sex, cause of liver failure, age, nutritional status, PELD/MELD score, graft type, biliary complications, and acute rejection was determined by Fisher's exact test; and association with length of stay by Cox proportional hazards regression analysis. Survival estimates were determined by the Kaplan‐Meier method. Sixty‐five children received one transplant and four had repeat transplants, totaling 69 procedures. Twenty‐nine BSI occurred in 19/69 (28%) procedures, mostly due to gram‐negative organisms, namely Klebsiella species . Risk for BSI was independently associated with biliary atresia (44% BSI in BA compared to 17% in non‐BA transplants; P = .014) and post‐operative biliary complications (55% BSI in transplants with biliary complications compared to 15% in those without; P = .0013). One‐year recipient and graft survival was 78% (CI 67%‐86%) and 77% (CI 65%‐85%), respectively. In Johannesburg, incident BSI, mostly from gram‐negative bacteria, were associated with biliary atresia and post‐operative biliary complications in children undergoing liver transplantation.

BACKGROUND In South Africa, there are no national guidelines for the conduct or quality assessment of colonoscopy, the gold standard for investigation and diagnosis of bowel pathology. OBJECTIVES To describe the clinical profile of patients and evaluate the practice of colonoscopy using procedural quality indicators at the Wits Donald Gordon Medical Centre (WDGMC) outpatient endoscopy unit (OEU). METHODS We conducted a prospective, clinical practice audit of colonoscopies performed on adults (≥18 years of age). A total of 1 643 patients were included in the study and variables that were collected enabled the assessment of adequacy of bowel preparation, length of withdrawal time and calculation of caecal intubation rate (CIR), polyp detection rate (PDR) and adenoma detection rate (ADR). We stratified PDR and ADR by sex, age, population group, withdrawal time and bowel preparation. CIR, PDR and ADR estimates were compared between patient groups by the χ2 test; Fisher's exact test was used for 2 × 2 tables. A p-value <0.05 was used. Benchmark recommendations by the American Society for Gastrointestinal Endoscopy (ASGE)/American College of Gastroenterology (ACG) Task Force on Colorectal Cancer (CRC) were used in this audit to assess individual endoscopist performance and that of the endoscopy unit as a whole. RESULTS The mean age of patients was 55.7 (standard deviation (SD) 14.4; range 18 - 91) years, ~60% were female, and the majority (75.5%) were white. Of the outpatients, 77.6% had adequate bowel preparation (ASGE/ACG benchmark ≥85%). The CIR was 97.0% overall, and screening colonoscopy was 96.3% (ASGE/ACG benchmark ≥90% overall and ≥95% for screening colonoscopies). The median withdrawal time for negative-result screening colonoscopies was 5.7 minutes (interquartile range (IQR) 4.2 - 9.3; range 1.1 - 20.6) (ASGE/ACG benchmark ≥ 6minutes), and PDR and ADR were 27.6% and 15.6%, respectively (ASGE/ACG benchmark ADR ≥25%). We demonstrated a 23.7% increase in PDR and 14.1% increase in ADR between scopes that had mean withdrawal times of ≥6 minutes and <6 minutes, respectively. Although the number of black Africans in the study was relatively small, our results showed that they have similar ADRs and PDRs to the white population group, contradicting popular belief. CONCLUSIONS The WDGMC OEU performed reasonably well against the international guidelines, despite some inadequacy in bowel preparation and lower than recommended median withdrawal times on negative-result colonoscopy. Annual auditing of clinical practice and availability of these data in the public domain will become standard of care, making this audit a baseline for longitudinal observation, assessing the impact of interventions, and contributing to the development of local guidelines.

BACKGROUND:For those with unresectable hepatocellular carcinoma, liver transplantation is considered the treatment of choice. Since 2006, the transplant programme at Wits Donald Gordon Medical Centre (WDGMC) has offered liver transplantation for selected patients with hepatocellular carcinoma. While the number of patients transplanted was small, we are unaware of any published data from Southern Africa describing outcomes in this group of liver transplant recipients. The aim of this study was to describe our experience as a case series.METHODS:The records of all patients with HCC who underwent deceased donor liver transplantation between April 2006 and March 2018 were reviewed retrospectively. Data were extracted from transplant clinic patient files, histopathology and pathology laboratory reports and an existing database of all liver transplant recipients at WDGMC. Patient survival was calculated from the time of transplant and survival estimates were determined by the Kaplan-Meier method.RESULTS:Thirty-one liver transplants were reviewed. The most common causes of underlying liver disease were infectious, mostly hepatitis B virus, and diseases of lifestyle including alcoholic/non-alcoholic steatohepatitis. Median age at transplant, 57 years (IQR 44-65 years), was younger than observed internationally, but consistent with reports from Africa. Male recipients predominated, in keeping with published trends. Overall, outcomes were worse than expected but for recipients who were within the University of California at San Francisco (UCSF) criteria for transplantation; survival was comparable to previously published data.CONCLUSION:Despite limitations, this is the first documented series of patients undergoing liver transplantation for HCC in South Africa and demonstrates that good results can be achieved in appropriately selected patients.
