Analysis of queries from nurses to the South African National HIV & TB Health Care Worker Hotline

Background. Since 2008, the Medicines Information Centre (MIC) has run the South African National HIV & TB Health Care Worker Hotline which provides free information on patient treatment to all healthcare workers in South Africa. With the introduction of nurse-initiated management of antiretroviral therapy (NIMART) in the public sector, the need for easy access to HIV and tuberculosis (TB) information has increased, especially among nurses. The hotline aims to provide this, most importantly to nurses in rural areas, where clinical staff often have little access to peer review. Objective. To describe the queries received from nurses by the hotline between 1 March and 31 May 2012 and identify problem areas and knowledge gaps where nurses may require further training. Methods. All queries received from nurses during the study period were analysed. An experienced information pharmacist reviewed all queries to identify knowledge gaps. Results. During the study period, the hotline received a total of 1 479 HIV- and TB-related queries from healthcare workers. Of these, 386 were received from nurses, of which 254 (66%) were NIMART-trained. The most common query subtopic was initiating antiretroviral therapy (ART) (20%), followed by adverse drug reactions (18%). The most common knowledge gap identified was the ability to interpret laboratory results before initiating ART (10%). Discussion. We conclude that the hotline is providing clinical help to an increasing number of nurses on the topic of treating HIV and TB throughout South Africa. In addition, queries directed to the hotline may assist in identifying knowledge gaps for the further training of nurses

Cases of antiretroviral-associated gynaecomastia reported to the National HIV & Tuberculosis Health Care Worker Hotline in South Africa

Background: Gynaecomastia is associated with exposure to antiretroviral therapy (ART), in particular efavirenz. There is limited data on clinical characteristics of patients with ART-associated gynaecomastia in resource-limited settings and little guidance on the optimal management of this adverse drug reaction (ADR). We describe the clinical characteristics, management and outcomes of gynaecomastia cases reported to the National HIV & Tuberculosis Health Care Worker Hotline in South Africa. Methods: We identified all gynaecomastia cases in adolescent boys and men on ART reported to the hotline between June 2013 and July 2014. We collected follow up data telephonically at monthly intervals to document clinical management and outcomes. Results: We received 51 reports of gynaecomastia between June 2013 and July 2014; 11% of the 475 patient-specific ADR queries to the hotline. All patients were on efavirenz-based ART. Mean age was 34 years (standard deviation 12) and seven were adolescents. The median onset of gynaecomastia was 15 months after efavirenz initiation (interquartile range 6–42). Gynaecomastia was bilateral in 29 patients (57%) and unilateral in 16 (31%). Serum testosterone was quantified in 25 of 35 patients with follow up data, and was low in 2 (8%). Efavirenz was replaced with an alternative antiretroviral in 29/35 patients (83%) and gynaecomastia improved in 20/29 (69%). Conclusions: Gynaecomastia was a frequently reported ADR in our setting, occurring with prolonged efavirenz exposure. Testosterone was low in the minority of tested cases. Most clinicians elected to switch patients off efavirenz, and gynaecomastia improved in the majority

The impact of the National HIV Health Care Worker Hotline on patient care in South Africa

<p>Abstract</p> <p>Background</p> <p>South Africa has a huge burden of illness due to HIV infection. Many health care workers managing HIV infected patients, particularly those in rural areas and primary care health facilities, have minimal access to information resources and to advice and support from experienced clinicians. The Medicines Information Centre, based in the Division of Clinical Pharmacology at the University of Cape Town, has been running the National HIV Health Care Worker (HCW) Hotline since 2008, providing free information for HIV treatment-related queries via telephone, fax and e-mail.</p> <p>Results</p> <p>A questionnaire-based study showed that 224 (44%) of the 511 calls that were received by the hotline during the 2-month study period were patient-specific. Ninety-four completed questionnaires were included in the analysis. Of these, 72 (77%) were from doctors, 13 (14%) from pharmacists and 9 (10%) from nurses. 96% of the callers surveyed took an action based on the advice received from the National HIV HCW Hotline. The majority of actions concerned the start, dose adaption, change, or discontinuation of medicines. Less frequent actions taken were adherence and lifestyle counselling, further investigations, referring or admission of patients.</p> <p>Conclusions</p> <p>The information provided by the National HIV HCW Hotline on patient-specific requests has a direct impact on the management of patients.</p

Understanding and responding to prescribing patterns of sodium valproate-containing medicines in pregnant women and women of childbearing age in Western Cape, South Africa

Growing evidence of the teratogenic potential of sodium valproate (VPA) has changed prescribing practices across the globe; however, the impact of this research and the consequent dissemination of a Dear Health Care Professional Letter (DHCPL) in December 2015, recommending avoidance of the teratogen VPA in women of childbearing age (WOCBA) and pregnant women in South Africa, is unknown. We explored trends and reasons for VPA use among pregnant women and WOCBA in the public sector in Western Cape Province from 1 January 2015 to 31 December 2017. Methods: Using the provincial health information exchange that collates routine electronic health data via unique patient identifiers, we analysed clinical and pharmacy records from 2015 to 2017 to determine prescription patterns of VPA and other antiepileptic drug (AED) and mood-stabilising medicine (MSM) use in WOCBA and pregnant women. Senior clinicians and policy makers were consulted to understand the determinants of VPA use. Results: At least one VPA prescription was dispensed to between 8205 (0.79%) and 9425 (0.94%) WOBCA from a cohort of approximately 1 million WOCBA attending provincial health care facilities per year
