Predictors of antibiotic prescriptions: a knowledge, attitude and practice survey among physicians in tertiary hospitals in Nigeria.

BACKGROUND: As part of the Global Action Plan against antimicrobial resistance (AMR), countries are required to generate local evidence to inform context-specific implementation of national action plans against AMR (NAPAR). We aimed to evaluate the knowledge, attitude, and practice (KAP) regarding antibiotic prescriptions (APR) and AMR among physicians in tertiary hospitals in Nigeria, and to determine predictors of KAP of APR and AMR. METHODS: In this cross-sectional study, we enrolled physicians practicing in tertiary hospitals from all six geopolitical zones of Nigeria. Implementation of an antimicrobial stewardship programmes (ASP) by each selected hospital were assessed using a 12 item ASP checklist. We used a structured self-administered questionnaire to assess the KAP of APR and AMR. Frequency of prescriptions of 18 different antibiotics in the prior 6 months was assessed using a Likert's scale. KAP and prescription (Pr) scores were classified as good (score ≥ 80%) or average/poor (score < 80%). Independent predictors of good knowledge, attitude, and practice (KAPPr) were ascertained using an unconditional logistic regression model. RESULTS: A total of 1324 physicians out of 1778 (74% response rate) practicing in 12 tertiary hospitals in 11 states across all six geopolitical zones participated in the study. None of the participating hospitals had a formal ASP programme and majority did not implement antimicrobial stewardship strategies. The median KAPPr scores were 71.1%, 77%, 75% and 53.3%, for the knowledge, attitude, practice, and prescription components, respectively. Only 22.3%, 40.3%, 31.6% and 31.7% of study respondents had good KAPPr, respectively. All respondents had prescribed one or more antibiotics in the prior 6 months, mostly Amoxicillin-clavulanate (98%), fluoroquinolones (97%), and ceftriaxone (96.8%). About 68% of respondents had prescribed antibiotics from the World Health Organization reserve group. Prior AMR training, professional rank, department, and hospital of practice were independently associated with good KAPPr. CONCLUSIONS: Our study suggests gaps in knowledge and attitude of APR and AMR with inappropriate prescriptions of antibiotics among physicians practicing in tertiary hospitals in Nigeria. Nigeria's NAPAR should also target establishment and improvement of ASP in hospitals and address institutional, educational, and professional factors that may influence emergence of AMR in Nigeria.

Positivity Rate, Predictors, and Outcome of Paediatric Lassa Fever Disease (LFD) in a Lassa Fever Endemic State, South-East Nigeria.

Background: The pattern and case fatality rate of Paediatric Lassa fever disease (LFD) is not well documented even in Lassa fever endemic communities. Aim and Objective: This prospective observational study was aimed at determining the pattern and outcome of Paediatric LFD. Methodology: A total of 183 children that met the criteria for LFD suspects were subjected to the Lassa virus PCR test. The suspects that tested positive were recruited into the study and a structured questionnaire was used to collect information on socio-demographics. Results: Of the 183 LFD suspects that were tested, 24 of them were positive to Lassa virus PCR, giving a positivity rate of 13.1%. The mean duration of illness before hospital presentation was 8.54 ± 3.83 days. All the subjects had a history of fever. Abdominal pain and vomiting were the two highest presenting complaints after fever. Seven out of 24 children died during the study period, giving a case fatality rate (CFR) of 29.2%. Subjects who presented with convulsions and unconsciousness (OR =10.00, 95% CI= 1.2, 81.81, p=0.020), bleeding (OR =40.00, 95% CI= 12.96, 539.67, p=0.020), poor urine output (OR =40.00, 95% CI= 12.96, 539.67, p=0.020) were more likely to die of LFD compared to their colleagues without such symptoms. Conclusion: The positivity rate and case fatality rate of LFD in children were high. Public enlightenment on the common features of Lassa fever disease and the need to seek health care early for children with febrile illness is advocated.
