Factors contributing to low use of HU among SCD patients exist in high-income countries. The latter leaves a drift of literature on factors for low utilization of HU in developing countries. This study aimed to explore the factors influencing the use of HU in the management of SCD in Tanzania. A qualitative study was employed to interview purposively selected participants for this study. The in-depth interviews were conducted with 11 parents of children with SCD, four medical doctors working at sickle cell clinics, and two representatives of the national health insurance fund (NHIF). Interviews were audio-recorded, transcribed, and thematically analysed. Barriers identified were misconception of parents on SCD, financial constraints, regulatory restrictions, worries and fears of medical doctors on the acceptability of HU, shortages of laboratory equipment and consumables, and limited availability of HU. Adequate knowledge of the parents and medical doctors on SCD and HU and opportunities for HU accessibility were the facilitators identified. The utilization of HU by the individual with SCD is affected by several factors, from individual to policy level. Nevertheless, parents of children with SCD and medical doctors working in sickle cell clinics demonstrated good knowledge of the diseases and HU.

Background: Jaundice is common among neonates and if untreated can lead to kernicterus. Diagnosing neonatal jaundice (NJ) using Kramer’s method (visual assessment) is considered user-friendly in resource-limited areas. However, there are conflicting findings on reliability of the Kramer’s method in the diagnosis of NJ, particularly of black descent. Therefore, study aimed to determine the accuracy of Kramer’s method in comparison to the total serum bilirubin (TSB) test in the diagnosis of NJ among neonates of black descent in Tanzania. Methods: A cross-sectional study was conducted between June and July 2020 at Muhimbili National Hospital (MNH) in Dar es Salaam Tanzania. A total of 315 neonates were recruited consecutively. In each neonate, jaundice was assessed using Kramer’s method and TSB test. NJ A total of 315 neonates were recruited i. A 2 X 2 table was created for the determination of sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), positive and negative likelihood ratios (+LR/−LR), and diagnostic accuracy (effectiveness) of Kramer’s method. Cohen kappa (κ) was used to analyze the agreement between Kramer’s method and TSB. Association between independent variables and presence of jaundice were assessed using the chi-square test and the p < 0.05 was considered to be statistically significant. Results: The prevalence of NJ was 49.8% by Kramer’s method and 63.5% by TSB. The Sensitivity, Specificity, PPV, and NPV of Kramer’s method were 70.5, 86.1, 89.8, and 62.6%, respectively. The +LR and –LR were 5.07 and 0.34, respectively. The diagnostic accuracy of Kramer’s method was 76.1%. There was a moderate agreement between Kramer’s method and TSB results (κ = 0.524, P<0.001). No significant relationship was observed between the independent variables and the presence of NJ. Conclusion: Kramer has a good positive predictive value. However, due to low sensitivity and NPV one cannot say that overall predictive ability is good. Also, clinical assessment by Kramer’s method should not be used for screening of NJ. Further studies are needed to investigate the utility of other non-invasive techniques in detecting NJ among neonates of black descent.

Tanzania is among the top five countries with a high burden of sickle cell disease (SCD) in the world. Even though the effects of SCD on quality of life have been documented in other countries including Nigeria and the United States of America, few are known from Tanzania. Therefore, this study focused on evaluating the effects of SCD on the quality of life among children living with SCD and their parents. The study employed a qualitative approach to interview purposively selected parents of children who have lived with SCD and have used hydroxyurea (HU) for more than 3 years. The in-depth interviews were conducted with 11 parents of children with SCD at the Muhimbili University of Health and Allied Sciences (MUHAS) in Dar-es-salaam, Tanzania. A semi-structured interview guide was used. Interviews were audio-recorded, transcribed, and thematically analyzed. Three themes were generated including psycho-social effects: family conflicts and divorce, limited access to education, stress and fear; financial effects: Employment limitation, reduced efficiency and productivity, loss of job and lack of self-keeping expenses; and physical effects: physical disability and dependence, and burden of the frequent crisis. Children living with SCD and their parents suffer psycho-social, financial, and physical impacts of the disease. Appropriate interventions should be introduced to minimize the observed effects as ways of improving the quality of life of the individuals living with SCD and their caregivers.

Background: Antibiotic resistance poses burden to the community and health-care services. Efforts are being made at local, national and global level to combat the rise of antibiotic resistance including antibiotic stewardship. Surveillance to antibiotic resistance is of importance to aid in planning and implementing infection prevention and control measures. The study was conducted to assess the resistance pattern to cefepime, clindamycin and meropenem, which are reserved antibiotics for use at tertiary hospitals in Tanzania. Methods: A hospital-based antibiotic resistance surveillance was conducted between July and November 2019 at Muhimbili National Hospital and Bugando Medical Center, Tanzania. All organisms isolated were identified based on colony morphology, Gram staining and relevant biochemical tests. Antibiotic susceptibility testing was performed on Muller-Hinton agar using Kirby-Bauer disc diffusion method. Antibiotic susceptibility was performed according to the protocol by National Committee for Clinical Laboratory Standards. Results: A total of 201 clinical samples were tested in this study. Urine (39.8%, n=80) and blood (35.3%, n=71) accounted for most of the collected samples followed by pus (16.9%, n=34). The bacterial resistance to clindamycin, cefepime and meropenem was 68.9%, 73.2% and 8.5%, respectively. About 68.4% Staphylococcus aureus isolates were resistant to clindamycin whereby 56.3%, 75.6%, 93.8% and 100% of the tested Escherichia coli, Klebsiella spp, Pseudomonas aeruginosa and Enterobacter cloacae, respectively, were cefepime resistant. About 8.5% of isolated Klebsiella spp were resistant and 6.4% had intermediate susceptibility to meropenem. Also, Pseudomonas aeruginosa was resistant by 31.2% and 25% had intermediate susceptibility to meropenem. Conclusion: The bacterial resistance to clindamycin and cefepime is high and low in meropenem. Henceforth, culture and susceptibility results should be used to guide the use of these antibiotics. Antibiotics with low resistance rate should be introduced to the reserve category and continuous antibiotic surveillance is warranted.

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.

Background: Studies assessing consumers’ knowledge of the rational use of antibiotics are essential to understand the knowledge gap before intervention strategies are instituted. Objectives: To assess the knowledge of rational use of antibiotics among consumers in Dar es Salaam, Tanzania. Methods: A cross-sectional study assessing knowledge of rational use of antibiotics among 960 consumers was conducted in Dar es salaam in March 2021. Participants were consecutively enrolled from outpatient pharmacies in selected public and private hospitals and marketplaces in Ilala Municipality. Data were collected using the WHO-validated questions on knowledge of consumers of antibiotic uses. Results: Overall, 196 (20.4%) and 503 (52.4%) participants demonstrated good knowledge of rational antibiotic use and conditions that can be treated with antibiotics, respectively. However, 678 (70.6%) responded that they stopped using antibiotics after dose completion, 515 (53.6%) would request the same antibiotic if it had helped to treat a similar condition in the past and 406 (42.3%) are willing to use the same antibiotic if a friend or family member used the medication previously to treat similar signs and symptoms. Besides, the following conditions were mentioned as being treatable with antibiotics: influenza (50.7%), sore throat (61.4%) and urinary tract infection (60.5%). Conclusions: The majority of the consumers had poor knowledge of the rational uses of antibiotics and a moderate proportion had good knowledge of the conditions that are treatable with antibiotics. Those with a high level of education and with health insurance had good knowledge of rational uses of antibiotics.
