Public attitudes to organ donation among a sample of urban-dwelling South African adults: a 2012 study.

BACKGROUND: Published literature suggests that attitudes toward organ donation in South Africa are generally positive. However, there has been a decline in the actual number of transplants taking place annually, which is not consistent with expressed positive attitudes. OBJECTIVES: Assess the attitudes of a representative sample of the urban-dwelling South African population toward organ donation and how these might affect transplant numbers. METHODS: A structured questionnaire was utilized to measure attitudes among a study population of 1048 adults in five major metropolitan areas of South Africa. Field work was undertaken by supervised field workers. Written informed consent was obtained from all participants. RESULTS: Eighty-nine percent (89%) of respondents had heard of organ donation, and 77% indicated that they would accept an organ transplant if necessary. Seventy percent (70%) of respondents specified they would be willing to donate their own organs after death, while 67% expressed willingness to donate a relative's organs after death. Participants were more positive about kidney donation than any other organ. CONCLUSION: Public attitudes toward organ donation among this population are generally positive. Recommendations include cultural and linguistic sensitivity in educational and advertising campaigns, as well as extensive research into other possible causes of organ shortage.

The novel application and effect of an ultraviolet light decontamination strategy on the healthcare acquisition of carbapenem-resistant Enterobacterales in a hospital setting.

BACKGROUND: The role of the hospital environment as contributory to healthcare acquisition of multidrug-resistant organisms (MDROs) is increasingly recognized. Ultraviolet light decontamination can minimize the environmental bioburden, thereby potentially reducing healthcare acquisition. This effect has been demonstrated for typical environmental MDROs, e.g. meticillin-resistant Staphylococcus aureus, vancomycin-resistant entero-cocci, and Clostridioides difficile; however, its role in reducing carbapenem-resistant Enterobacterales (CRE) incidence rates is unclear. AIM: To evaluate the impact of continuous ultraviolet light (C-UV) on healthcare acquisition rates of CRE. METHODS: A 26-month pragmatic, prospective interventional study with addition of C-UV decontamination to standard cleaning was conducted in units at high risk for CRE acquisition. Introduction of C-UV followed a 12 month baseline period, with a two-month wash-in period. Implementation included terminal decontamination at discharge and a novel in-use protocol, whereby rooms occupied for ≥48 h were decontaminated during the course of the patients' in-hospital stay. Incidence density rates of CRE during the intervention period were compared to the baseline period using interrupted time series regression. Rates were adjusted for ward/admission prevalence and analysed according to C-UV protocol. FINDINGS: The in-use C-UV protocol demonstrated a significant negative association with the incidence density rate of CRE when adjusting for CRE admission rate (P = 0.0069). CRE incidence density rates decreased significantly during the intervention period (P = 0.042). Non-intervention units demonstrated no change in incidence density rates when adjusting for ward and/or admission prevalence. CONCLUSION: C-UV decontamination can potentially reduce healthcare acquisition of CRE when implemented with an in-use protocol.

Practising in a post-truth world: Pandemic ethics can inform patient autonomy and clinical communication.

The COVID-19 pandemic posed an unprecedented challenge to modern bioethical frameworks in the clinical setting. Now, as the pandemic stabilises and we learn to 'live with COVID', the medical community has a duty to evaluate its response to the challenge, and reassess our ethical reasoning, considering how we practise in the future. This article considers a number of clinical and bioethical challenges encountered by the author team and colleagues during the most severe waves of the pandemic. We argue that the changed clinical context may require reframing our ethical thought in such a manner as to adequately accommodate all parties in the clinical interaction. We argue that clinicians have become relatively disempowered by the 'infodemic', and do not necessarily have adequate skills or training to assess the scientific literature being published at an unprecedented rate. Conversely, we acknowledge that patients and families are more empowered by the infodemic, and bring this empowerment to bear on the clinical consultation. Sometimes these interactions can be unpleasant and threatening, and involve inviting clinicians to practise against best evidence or even illegally. Generally, these requests are framed within 'patient autonomy' (which some patients or families perceive to be unlimited), and several factors may prevent clinicians from adequately navigating these requests. In this article, we conclude that embracing a framework of shared decision-making (SDM), which openly acknowledges clinical expertise and in which patient and family autonomy is carefully balanced against other bioethics principles, could serve us well going forward. One such principle is the recognition of clinician expertise as holding weight in the clinical encounter, when framed in terms of non-maleficence and beneficence. Such a framework incorporates much of our learning and experience from advising and treating patients during the pandemic.

It's contrary - comorbidity does not affect survival of South Africans with colorectal cancer: An analysis from the Colorectal Cancer in South Africa cohort.

BACKGROUND: The 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. OBJECTIVES: To determine the prevalence of comorbidity and whether comorbidity adversely affects overall survival (OS) of CRC patients. METHODS: Patients 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. RESULTS: There 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. CONCLUSIONS: In 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.

Reimagining liver transplantation in South Africa: A model for justice, equity and capacity building - the Wits Donald Gordon Medical Centre experience.

The challenge of providing effective and integrated liver transplant services across South Africa's two socioeconomically disparate healthcare sectors has been faced by Wits Donald Gordon Medical Centre (WDGMC) since 2004. WDGMC is a private academic hospital in Johannesburg and serves to supplement the specialist and subspecialist medical training provided by the University of the Witwatersrand. Over the past 14 years, our liver transplant programme has evolved from a sometimes fractured service into the largest-volume liver centre in sub-Saharan Africa. The growth of our programme has been the result of a number of innovative strategies tailored to the unique nature of transplant service provision. These include an employment model for doctors, a robust training and research programme, and a collaboration with the Gauteng Department of Health (GDoH) that allows us to provide liver transplantation to state sector patients and promotes equality. We have also encountered numerous challenges, and these continue, especially in our endeavour to make access to liver transplantation equitable but also an economically viable option for our hospital. In this article, we detail the liver transplant model at WDGMC, fully outlining the successes, challenges and innovations that have arisen through considering the provision of transplant services from a different perspective. We focus particularly on the collaboration with the GDoH, which is unique and may serve as a valuable source of information for others wishing to establish similar partnerships, especially as National Health Insurance comes into effect.

Increasing deceased organ donor numbers in Johannesburg, South Africa: 18-month results of the Wits Transplant Procurement Model.

In 2016, deceased-donor organ procurement at Wits Transplant, based at Wits Donald Gordon Medical Centre in Johannesburg, South Africa (SA), was in a state of crisis. As it is the largest-volume solid-organ transplant unit in SA, and as we aspire to provide transplant services of an international standard, the time to address our procurement practice had come. The number of deceased donors consented through our centre was very low, and we needed a radical change to improve our performance. This article describes the Wits Transplant Procurement Model - the result of our work to improve procurement at our centre. The model has two core phases, one to increase referrals and the other to improve our consent rates. Within these phases there are several initiatives. To improve referrals, the threefold approach of procurement management, acknowledgement and resource utilisation was developed. In order to 'convert' referrals into consents, we established the Wits Transplant 'Family Approach to Consent for Transplant Strategy' (FACTS). Since initiation of the Wits Transplant Procurement Model, both our referral numbers from targeted hospitals and our conversion rates have increased. Referrals from targeted hospitals increased by 54% (from 31 to 57). Our consent rate increased from 25% (n=6) to 73% (n=35) after the initiation of Wits Transplant FACTS. We hope that other transplant centres in SA and further afield in the region will find this article helpful, and to this end we have created a handbook on the Wits Transplant Procurement Model that is freely available for download (http://www.dgmc.co.za/docs/Wits-Transplant-Procurement-Handbook.pdf).

A one year audit of the Colorectal Unit at Wits Donald Gordon Medical Centre: 2016-2017.

BACKGROUND: Colorectal surgery has developed into an established surgical subspecialty in South Africa, however there is a paucity of data regarding the epidemiology and surgical outcomes of patients with colorectal disease in this country. The objective is to present the findings of a one-year audit of the Wits Donald Gordon Medical Centre (WDGMC) Colorectal Unit with specific reference to indications, surgical procedures and patient outcomes. METHOD: Patient files from December 2016 to November 2017 were included in a retrospective analysis. The Mann-Whitney U test was used to analyse continuous variables and the Chi-squared test was used to compare categorical variables. RESULTS: During the audit period, 1264 patients were admitted to the Colorectal Unit and a further 564 outpatient endoscopic procedures were performed. There were 306 emergency admissions. 139 elective colorectal resections took place, with a 16% major complication rate, a 12% anastomotic leak rate and no deaths. Rectal resections constituted 66% of the operations and 34% were colonic resections. The median length of stay for all patients undergoing resection was 9 days and there was no statistically significant difference in length of stay between open and laparoscopic cases. CONCLUSION: The WDGMC Colorectal Unit manages a high volume of patients presenting with the full spectrum of colorectal disease.

Attitudes to organ donation among some urban South African populations remain unchanged: a cross-sectional study (1993 - 2013).

BACKGROUND: A 1993 paper in the SAMJ suggested that public attitudes to organ donation in South Africa were positive. However, statistics reveal a decline in the annual number of transplants in this country. OBJECTIVE: To repeat the 1993 survey as far as possible and determine whether public attitudes to organ donation in some South African populations have changed over the past 20 years. METHODS: The 1993 study was replicated in 2012 to generate a current data set. This was compared with the raw data from the 1993 study, and an analysis of percentages was used to determine variations. RESULTS: Generally attitudes to organ donation have not changed since 1993, remaining positive among the study population. However, individuals are significantly more hesitant to consider donating the organs of a relative without being aware of that person's donation preference. Individuals in the black African study population are currently more willing to donate kidneys than in 1993 (66% v. 81%; p < 0.0001), but less willing to donate a heart (64% v. 38%; p < 0.0001), a liver (40% v. 34%; p < 0.036) and corneas (22% v. 15%, p < 0.0059). CONCLUSIONS: Publicity campaigns aimed at raising awareness of organ donation should emphasise the importance of sharing donation preferences with one's family in order to mitigate discomfort about making a decision on behalf of another. These campaigns should be culturally and linguistically sensitive. The study should be repeated in all populations over time to continually gauge attitudes.
