Pharmacovigilance and Adverse Drug Reactions Reporting: Healthcare Providers' Experiences from Southern Highland Tanzania.

Purpose: This exploratory qualitative study aimed to analyze the experiences of healthcare providers (HCPs) in pharmacovigilance (PV) and ADR reporting in the southern highland zone of Tanzania. Methods: In 2022, an exploratory qualitative case study using in-depth interviews (IDIs) was conducted to explore the experiences of PV and ADR reporting among HCPs (doctors, nurses, and pharmacists). The study was carried out in a zonal referral hospital and a regional referral hospital of the Tanzanian southern highlands zone. Inductive-deductive thematic analysis was adopted for data analysis. Results: Participants demonstrated adequate knowledge of PV and its related activities including ADR reporting. Knowing the interactions and wrong medication dosage as sources of ADR, signs, and symptoms, stopping the drug, and treating the symptoms following ADR emerged as subthemes linked with adequate knowledge in identifying and managing ADR. Participants perceived reporting ADR as laborious, posing a subjective burden and that not all ADRs needed to be reported. The latter contributed to limited participation in ADR reporting despite that participants were conversant with both physical and online ADR reporting platforms. Conclusion: Although HCPs are well informed about PV and ADR reporting including the benefits to public health, their involvement in ADR reporting is low. In addition to the ongoing on-the-job training and regular supportive supervision for HCPs to improve the ADR practice, there is still a need to explore other strategies to be used as motives for HCPs to report ADR regularly.

Prevalence of urinary tract infection and antimicrobial resistance patterns of uropathogens with biofilm forming capacity among outpatients in morogoro, Tanzania: a cross-sectional study.

INTRODUCTION: Urinary tract infection (UTI) is the second most common infectious disease affecting more than 150 million people globally annually. Uropathogenic E. coli (UPEC), the predominant cause of UTI, can occur as a biofilm associated with antimicrobial resistance (AMR). There is a data gap on global AMR patterns from low-income settings, including Tanzania. Data on antimicrobial susceptibility patterns in relation to biofilm formation will help in the proper selection of antibiotics and the fight against AMR. METHODS: This analytical cross-sectional study was conducted among consecutively selected outpatients (n = 344) from January to May 2022 at Morogoro Regional Referal Hospital. Mid-stream urine samples were collected aseptically from symptomatic patients. A significant UTI was defined when more than 105 colonies/ml of urine were recorded. Kirby Bauer's disc diffusion method was used for antibiotics susceptibility patterns and a Congo Red Agar method was used to determine biofilm formation. Two-sided χ2 test or Fisher's exact test, Cohen's kappa coefficient and logistic regression were used for data analysis. A p-value < 0.05 was considered statistically significant. RESULTS: The prevalence of UTIs was 41% (141/344) and elders (>=60 years) had five times higher odds of having UTI as compared to adolescents (p < 0.001). E. coli was the most predominant bacteria (47%; 66/141), which displayed moderate susceptibility against ciprofloxacin (59.1%) and nitrofurantoin (57.6%). A total of 72 (51%) of all isolated bacteria were multi-drug resistant. All isolated bacteria demonstrated high resistance (> 85%) against ampicillin and co-trimoxazole. In this study, 51.5% (34/66) were biofilm-forming E. coli and demonstrated relatively higher antibiotic resistance as compared to non-biofilm forming bacteria (p < 0.05). CONCLUSION: We report high antibiotic resistance against commonly used antibiotics. Slightly more than half of the isolated bacteria were biofilm forming E. coli. A need to strengthen stewardship programs is urgently advocated.

Awareness, Actions, and Predictors of Actions on Adverse Drug Reaction Reporting among Patients Attending a Referral Hospital in Southern Highland Tanzania.

Purpose: This study assessed the awareness, actions, and predictors of actions on adverse drug reaction reporting among patients attending a referral hospital in southern highland Tanzania. Methods: A hospital-based cross-sectional study was conducted from January to August 2022 at Mbeya Zonal Referral Hospital (MZRH) in Mbeya, Tanzania. A total of 792 adult patients with chronic conditions attending outpatient clinics at MZRH were recruited consecutively. A semistructured questionnaire was used to collect demographic characteristics, ADR awareness, and actions when encountering ADR. Data were analyzed using the statistical package for social sciences (SPSS) version 23 and results are summarized using frequency and percentages. Binary logistic regression was used to assess the predictors associated with reporting ADR among patients. P value ≤0.05 was considered statistically significant. Results: Out of 792, 397 (50.1%) were males and 383 (48.6%) had a primary education level. Only 171 (21.6%) participants previously experienced ADR, and 111 (14.1%) were aware that ADR is an unexpected harm that occurs after medication use. The majority 597 (70.3%) of the participants said will report ADR to healthcare providers, 706 (88.9%) prefer reporting ADR to healthcare providers, and 558 (69.1%) said patients are not aware of the importance of reporting ADR. Patients aged below 65 years of age, unemployed ((AOR (95% CI) = 0.4 (0.18-0.87), self-employed ((AOR (95% CI) = 0.5 (0.32-0.83)), and those who ever encountered ADR ((AOR (95% CI) = 0.1 (0.05-0.11)) were more likely to report the ADR to HCPs compared to the rest. Conclusions: The majority of patients are not aware of what is ADR and the importance of ADR reporting. Most of the patients prefer to report ADR to healthcare providers. We recommend an awareness campaign to raise awareness of the patients on ADR and other methods of ADR reporting.
