A framework for the use of biological medicines in the free state province, South Africa.

PURPOSE: The use of biological medicines (BM) has increased worldwide owing to their effectiveness in the treatment of many chronic diseases. However, in South Africa, access to BM remains limited, hence, there is a need to develop strategies that will enable timely access to BM by all patients who need them. OBJECTIVE: To develop a framework for the use of BM in South Africa. METHODS: Using a Delphi questionnaire that was developed by integration of the opinions of newly qualified doctors (<2 years practice), prescribing specialists, and patients using BM, a Delphi method was used to guide an experts' panel into consensus on the different opinions in the questionnaire, and from this, a framework for the use of BM was constructed. RESULTS: From the surveys, 76.2% of the newly qualified doctors and 91.7% of the prescribing specialists indicated that they had limited knowledge on the pharmacology of BM, and, respectively, 64.5% and 77.8% admitted that their knowledge on BM was not adequate for prescribing and taking care of patients on BM. Also, 58.3% and 75% of the prescribers indicated that the high cost and the tedious procurement process, respectively, were barriers of access to BM. The Delphi panel reached consensus after two rounds, and the resultant framework recommends that, appropriate use of BM requires establishing guidelines for the use of BM, increasing BM content in the medical training programs and information resources used by healthcare professionals, enacting drug regulations and drug policies that will increase availability of BM, offering appropriate patient information and public engagement. CONCLUSION: The lack of knowledge on BM by health professionals, together with the high cost and a complex procurement processes are the major impediment to access to BM. A framework for the use of BM in South Africa was successfully developed to address these and other challenges.

A clinical audit of red blood cell transfusion practices at a district hospital in South Africa.

BACKGROUND:  Red blood cell (RBC) transfusion is one of the most critical and expensive lifesaving treatment modalities. A clinical audit is a valuable instrument to determine whether transfusion practices align with the guidelines and identify knowledge deficiencies. The study aimed to evaluate the RBC transfusion practices and patient outcomes at the National District Hospital in Bloemfontein, South Africa, and to determine adherence to transfusion guidelines. METHODS:  A retrospective descriptive study was conducted. All blood transfusion registers in the hospital were used to identify transfusion episodes during the study period. Files were retrieved from the admissions office and information captured on a paper-based datasheet. The appropriateness of the transfusion and adherence to the South African transfusion guidelines were evaluated using specific criteria. RESULTS:  Of the 118 transfusion episodes during the study period, 78 files were retrieved and 76 included in the study. The patients' median age was 47 years (interquartile range [IQR]: 32-66 years), with human immunodeficiency viruses (HIV) (n = 34; 44.7%) being the most common comorbid condition. Pre-transfusion haemoglobin was documented for all patients with a median of 4.6 g/dL (IQR: 3.95 g/dL - 5.5 g/dL). The audit revealed that in 68.4% (n = 52) of the cases, the guidelines were applied appropriately. CONCLUSION:  The study described the blood transfusion practices and identified shortcomings when compared with the standard clinical guidelines.Contribution: The study highlights the importance of applying rationale, caution and consideration of the specific patient profile when performing transfusions.

Colonisation with multidrug-resistant organisms among dialysis patients at Universitas Academic Hospital.

Background: While most infections with multidrug-resistant organisms (MDROs) affect colonised people, there is limited evidence on MDRO colonisation in South African dialysis patients. Objectives: This study evaluated the prevalence of MDRO colonisation among dialysis patients, the resistance patterns of each MDRO and the risk factors for colonisation. Method: Rectal and nasal swabs were collected from dialysis patients who consented to participate in a 5-month study to identify selected MDROs (April 2021 - August 2021). Specimens were cultured on selected chromogenic media. Data collected included demographics, clinical information from medical records and laboratory results. Results: Multidrug-resistant organisms were isolated from 17 (23.9%) of the 71 enrolled participants. Of the 23 MDRO strains from rectal swabs (n = 71), extended-spectrum beta-lactamase-producing Enterobacterales accounted for 21.1% (15/71), vancomycin-resistant enterococci 2.8% (n = 2/71) and carbapenem-resistant Enterobacterales 4.2% (n = 3/71). Klebsiella pneumoniae (65.2%, n = 15/23) was the most prevalent MDRO. More than 80% resistance to trimethoprim and sulfamethoxazole, cefotaxine, and ciprofloxacin was noted. Significant risk factors included previous hospitalisation, proton pump inhibitor use and antibiotic exposure in the past 6 months. Conclusion: Multidrug-resistant organisms' carriage was high in our dialysis population. The infection prevention and control measures need to be revised and strengthened. Contribution: This study falls within the scope of the SAJID journal as it is the first within sub-Sahara Africa to report that approximately one-fifth of dialysis patients were colonised with MDRO, which is a significant risk for MDRO infections.

High seroprevalence of hepatitis E virus in the Free State province of South Africa.

The seroepidemiology of hepatitis E virus (HEV) in South Africa is limited. We investigated anti-HEV IgM and IgG, in residual hepatitis A, B, and C negative serology specimens, at our public sector Free State (FS) laboratory. Of 299 specimens (01 May-31 October 2020), 182/299 (60.9%) had anti-HEV IgG and 1/299 (0.33%) had anti-HEV IgM. High HEV seroprevalence across different age groups suggests a different epidemiology in the FS, necessitating further research. Contribution: The need for HEV research in South Africa is highlighted. Clinicians should consider HEV in their differential diagnosis of patients with hepatitis.

A Retrospective Review of Neglected Tropical Diseases Diagnosed on Histopathological Specimens in the Free State Province, South Africa, 2015-2020.

Background: Neglected tropical diseases (NTDs) are a heterogeneous group of medical conditions that commonly occur in underprivileged populations. NTDs are primarily diagnosed in tropical areas. Although South Africa is not situated in a tropical region, the high poverty rate makes the country susceptible to some NTDs. Limited data are available on the burden of NTDs in the Free State province of South Africa. This study aimed to determine the number of NTDs diagnosed on histopathological specimens in the public sector of the Free State province over a six-year period and to evaluate the patient demographics. Methods: A retrospective, descriptive study was performed. All NTDs diagnosed in histopathological specimens from public sector hospitals in the province submitted to the Department of Anatomical Pathology, National Health Laboratory Service, and University of the Free State between 1 January 2015 and 31 December 2020 were included in the study. The demographic information, biopsy site, and referring hospital were noted for each case identified. Results: A total of 72 NTDs were diagnosed. The five most common diagnoses were echinococcosis (n = 33; 45.8%), bilharzia (n = 13; 18.1%), leprosy (n = 9; 12.5%), mycetoma (n = 8; 11.1%), and intestinal worms (n = 5; 6.9%). Ten (30.3%) patients diagnosed with echinococcosis came from the Free State's neighbouring country, Lesotho. Conclusion: Echinococcosis was the most prevalent NTD diagnosed in central South Africa. We recommend that the South African Department of Health add echinococcosis to the principal NTDs of significance in South Africa, alongside soil-transmitted helminths, schistosomiasis, leprosy, and rabies.

Healthcare providers' knowledge, attitudes and practices on smoking cessation intervention in the Northern Cape.

Background: Clinicians are crucial in encouraging smokers to quit through behavioural or pharmacological smoking cessation interventions. Smokers quit better with professional help. The level of healthcare providers' (HCPs) knowledge, attitudes and counselling skills related to effective smoking cessation support in the study area remains uncertain. Aim: The study aimed to determine HCPs' knowledge, attitudes and practices (KAP) on smoking cessation intervention strategies in the Sol Plaatje district, Northern Cape. Setting: Sol Plaatje's 13 district municipality clinics, Kimberley, Northern Cape. Method: A descriptive, cross-sectional analytical study involving healthcare workers in the above setting. Results: A total of 165 HCPs, including medical officers, professional nurses, enrolled nurses and assistant-enrolled nurses working in primary healthcare clinics, were invited to participate in the study, with 156 completing the questionnaires. About 53.9% had no knowledge of South African tobacco smoking cessation guidelines, while 87.2% knew the importance of counselling patients about smoking and its impact on quitting. The majority of them did not know the medicines recommended for tobacco treatment in South Africa. About 89.7% expressed that smoking cessation counselling is an important part of their jobs. However, less than half indicated that they make follow-up arrangements for those attempting to quit. Conclusion: The study revealed gaps in KAP regarding smoking cessation among the respondents, necessitating the need for continuing education on the existing smoking cessation guidelines among these HCPs. Contribution: The results of this study will help to improve smoking cessation intervention knowledge among health providers.

Knowledge, attitudes and practices on diabetic foot care among nurses in Kimberley, South Africa.

BACKGROUND:  Diabetic foot is a dangerous complication of diabetes and can lead to high morbidity and mortality. As essential team members of the healthcare system, nurses play an important role in diabetic foot management and are indispensable in patients' education to prevent diabetic foot. The study assessed nurses' knowledge, attitudes and practices regarding diabetic foot care in Sol Plaatje primary health care centres in the Northern Cape: Sol Plaatje's 14 district municipality clinics, Kimberley, Northern Cape. METHODS:  This was a descriptive cross-sectional analytical study. A questionnaire assessed nurses' knowledge, practices and attitudes towards diabetic foot care in the above setting. RESULTS:  A total of 128 professionals, enrolled and auxiliary nurses who are providing primary care to patients within the 14 clinics in the Sol-Plaatje sub-district were recruited for the study. Hundred and five participants completed the self-administered questionnaires. The majority (95%) were females and 58.1% knew that South African Diabetic Foot Guidelines existed, while 57.7% had read them. About 57% did not know about the 60-s diabetic foot screening tool, and 67% did not know the 10 g monofilament test. Approximately 29.8% had never attended a class on diabetic foot care and 85.6% required training on diabetic foot care. CONCLUSION:  This study revealed that the majority of nurses working in the Sol-Plaatje sub-district primary health care centres are knowledgeable of the diabetic foot guidelines for primary care. However, there is a need for ongoing education on diabetic foot care.Contribution: The study results will help improve nurses' awareness of the importance of diabetic foot care.

Prevalence of metabolic syndrome among adults treated at a district hospital outpatient department.

BACKGROUND:  Metabolic syndrome (MetS) is a collection of risk factors, including hypertension, high fasting blood glucose, high fasting triglyceride and low high-density lipoprotein (HDL) cholesterol levels that may increase the risk for cardiovascular disease and type 2 diabetes. The study aimed to determine the prevalence of MetS among adults attending a Free State district hospital's outpatient department. METHODS:  A cross-sectional study included a consecutive sample of consenting patients 18 years and older from 18 October 2021 to 19 November 2021. Patients' waist circumference was measured, and data were extracted from patients' files. RESULTS:  The 409 participants were predominantly females (64.2%). The median age was 60 years. Triglyceride and HDL cholesterol levels were available for 27.4% and 26.9% of patients, respectively. Of the 278 (68.0%) patients with sufficient information to determine their MetS status, 187 (67.3%) had MetS. Of the males with sufficient information, 49.1% (n = 56/114) had MetS compared to 79.9% (n = 131/164) of the females with sufficient information (p  0.001). The age group 60-79 years had the highest prevalence (76.7%, p  0.001). In all race groups, at least two-thirds of patients had MetS (p = 0.831). CONCLUSION:  Incomplete patient notes and failure to do investigations led to a third of patients not having sufficient information to determine their MetS status. In patients with sufficient information, a high prevalence of MetS was found.Contribution: This study highlights the challenges of determining MetS retrospectively in an outpatient population and the need for completeness of medical note keeping and routine investigations in high-risk patients. It also notes the high prevalence of MetS.

Clinical review of stroke care at National District Hospital, Bloemfontein.

BACKGROUND: Stroke is a leading cause of morbidity and mortality affecting sub-Saharan Africa. Studies show that dedicated stroke units improve patient outcomes. National District Hospital (NDH) manages strokes, with the potential of becoming a dedicated stroke unit in Bloemfontein, South Africa. The study aimed to describe the clinical characteristics, management and outcomes of patients presenting with stroke at NDH. METHODS: In this retrospective descriptive study, emergency department registers were used to identify patients presenting with symptoms of a stroke between 01 January 2019 and 31 March 2019. Relevant data were extracted from hospital files. RESULTS: Of the 106 identified patients, 53 were included in the study. The median age was 61 years (range 28-89 years), with an almost equal split between genders. The most common risk factor was hypertension (81.3%). The median time from symptom onset to presentation at NDH was 9 h. No patient received thrombolysis. One patient received neurosurgical intervention. The most prescribed secondary preventative drugs were antihypertensive medication, statins, anticoagulation and antiretroviral therapy. Half (52.8%) of the patients received rehabilitation as in-patients. Final diagnoses were ischaemic strokes (26/53, 49.0%), transient ischaemic attacks (10/56, 22.7%) and haemorrhagic strokes (6/56, 13.6%). The 6-month post-infarct mortality rate was 37.5%. CONCLUSION: Patient outcomes were comparable to similar South African studies. Time delays in stroke management remain a major obstacle. Identified action points include community education, improving emergency medical services and establishing a dedicated stroke unit.Contribution: This study underlines the importance of stroke and cardiovascular disease prevention and stresses the value of establishing dedicated stroke units.

Comparison between ultrasound and chest X-ray to confirm central venous catheter tip position.

Background: Mechanical central venous catheter (CVC) placement complications are mostly malposition or iatrogenic pneumothorax. Verification of catheter position by chest X-ray (CXR) is usually performed postoperatively. Objectives: This prospective observational study assessed the diagnostic accuracy of peri-operative ultrasound and a 'bubble test' to detect malposition and pneumothorax. Method: Sixty-one patients undergoing peri-operative CVC placement were included. An ultrasound protocol was used to directly visualise the CVC, perform the 'bubble test' and assess for the presence of pneumothorax. The time from agitated saline injection to visualisation of microbubbles in the right atrium was evaluated to determine the correct position of the CVC. The time required to perform the ultrasound assessment was compared to that of conducting the CXR. Results: Chest X-ray identified 12 (19.7%) malpositions while ultrasound identified 8 (13.1%). Ultrasound showed a sensitivity of 0.85 (95% confidence interval [CI]: 0.72 to 0.93) and a specificity of 0.5 (95% CI: 0.16 to 0.84). The positive and negative predictive values were 0.92 (95% CI: 0.80 to 0.98) and 0.33 (95% CI: 0.10 to 0.65), respectively. No pneumothorax was identified on ultrasound and CXR. The median time for ultrasound assessment was significantly shorter at 4 min (interquartile range [IQR]: 3-6 min), compared to performing a CXR that required a median time of 29 min (IQR: 18-56 min) (p < 0.0001). Conclusion: This study showed that ultrasound produced a high sensitivity and moderate specificity in detecting CVC malposition. Contribution: Ultrasound can improve efficiency when used as a rapid bedside screening test to detect CVC malposition.
