Implementation of data triangulation and dashboard development for COVID-19 vaccine adverse event following immunisation (AEFI) data in Nigeria.

Nigeria began administering COVID-19 vaccines on 5 March 2021 and is working towards the WHO's African regional goal to fully vaccinate 70% of their eligible population by December 2022. Nigeria's COVID-19 vaccination information system includes a surveillance system for COVID-19 adverse events following immunisation (AEFI), but as of April 2021, AEFI data were being collected and managed by multiple groups and lacked routine analysis and use for action. To fill this gap in COVID-19 vaccine safety monitoring, between April 2021 and June 2022, the US Centers for Disease Control and Prevention, in collaboration with other implementing partners led by the Institute of Human Virology Nigeria, supported the Government of Nigeria to triangulate existing COVID-19 AEFI data. This paper describes the process of implementing published draft guidelines for data triangulation for COVID-19 AEFI data in Nigeria. Here, we focus on the process of implementing data triangulation rather than analysing the results and impacts of triangulation. Work began by mapping the flow of COVID-19 AEFI data, engaging stakeholders and building a data management system to intake and store all shared data. These datasets were used to create an online dashboard with key indicators selected based on existing WHO guidelines and national guidance. The dashboard went through an iterative review before dissemination to stakeholders. This case study highlights a successful example of implementing data triangulation for rapid use of AEFI data for decision-making and emphasises the importance of stakeholder engagement and strong data governance structures to make data triangulation successful.

Pattern, awareness and perceptions of health hazards associated with self medication among adult residents of kano metropolis, northwestern Nigeria.

BACKGROUND: Kano State is the most populous state, and one of those states pronounced with the highest prevalence of drug abuse in Nigeria. However, there is lack of documented data to back the assertion. OBJECTIVE: We determined the pattern, awareness and perceptions of the adult residents of Kano metropolis about self medication. MATERIALS AND METHODS: We used a descriptive cross-sectional design to study a random sample of 380 adult in Kano metropolis. Data was collected using semi-structured questionnaires that were pretested outside the study area. Data analysis was with Epi Info® 3.5.1. RESULTS: The mean age of the subjects was 35.43 ± 15.10 years, majority were males (66.32%), singles (47.11%) and had at least secondary education (67.63%). About three-quarter (78.95%) admitted using drug (s) in the past without prescription. Drugs commonly consumed were antimalarials (42.10%), analgesics (40.56%), antibiotics (29.41%), and cough mixtures (13.31%). Common sources of drugs were patent medicine stores (62.54%) and the market (19.81%). Common reasons for self medication were long queues in the hospitals (38.39%), and in-accessibility to doctors (25.08%). About two-thirds (65.00%) correctly perceived that self medication could be hazardous; and half (51.58%) were aware of at least one hazard of self medication. CONCLUSION/RECOMMENDATIONS: Irrational drug use is a growing challenge to public health in Kano, Nigeria. Thus, drug regulatory agencies in Nigeria should work together to ensure that all drug retail outlets and drug sellers are registered, controlled drugs are dispensed only on prescription of the physicians; and the laws safeguarding drug use are duly enforced. Health authorities should also strengthen efforts towards health educating the public.

Physicians' practice for prevention of venous thromboembolism in medical patients.

OBJECTIVE: To audit physicians' practice of providing prophylaxis for venous thromboembolism (VTE) in patients admitted to acute- care medical wards and to determine the consequences of lack of prophylaxis. DESIGN: Case-control comparative study. PLACE AND DURATION OF STUDY: All patients admitted to medical service of Riyadh Medical Complex (RMC) who stayed longer than six days were studied between July 2001 and 2002. PATIENTS AND METHODS: Demographic data as well as risk factors for VTE were identified for all patients who were divided in two groups. Patients who received prophylaxis (group-A) and those who did not (group-B) were both followed up. Type of prophylaxis and any complications were documented. Duplex ultrasound of the lower limbs was done in all patients in both groups and the outcome for all patients were documented. RESULTS: Two hundred and forty-nine (249) patients were studied. Ninety-eight (39.35%) patients (group-A) received prophylaxis for VTE, while 151 (60.65%) patients (group-B) did not receive prophylaxis. Twenty-five point eight percent (25.8%), 37.5%, and 50% of patients with 3, 4 and 5 risk factors respectively did not receive thromboprophylaxis. Duplex sonography did not reveal deep venous thrombosis (DVT) in any patient of the two groups in hospital and upto one month after discharge. There was no statistical difference in mortality between the two groups. CONCLUSION: Physicians' practice showed low threshold for providing VTE prophylaxis for medical patients. This was not translated to higher incidence of VTE or higher hospital mortality.
