RESUMO

BACKGROUND: Vaccines prevent infections and could subsequently reduce antimicrobial use. A 1-week mass vaccination campaign was done with Typbar-TCV (Bharat Biotech, Hyderabad, India) between Feb 25 and March 4, 2019. We investigated whether this typhoid conjugate vaccine campaign could affect antimicrobial prescribing in children presenting to primary care in Harare, Zimbabwe. METHODS: In this mixed methods study, data for acute paediatric outpatient consultations between Jan 1, 2018, and March 31, 2020, were collected from five clinics in Harare. Interrupted time series analysis was done to compare prescription data before and after the campaign. To contextualise findings, qualitative data were collected between April 20, 2021, and July 20, 2022, comprising ethnographic research (ie, workshops, surveys, observations, and interviews) in 14 clinics. Ethnographic data were used for thematic analysis. The primary outcome was monthly antimicrobial prescriptions in children aged 6 months to 15 years, normalised by the number of trauma events in all age groups. FINDINGS: In the data collection period, 27 107 paediatric consultations were recorded. 17 951 (66·2%) of 27 107 children were prescribed antimicrobials. Despite the perceived reduction in typhoid cases and a decreasing trend in the prescription of antimicrobials commonly used to treat typhoid (ie, ciprofloxacin and azithromycin), mass vaccination with Typbar-TCV did not affect the total rate of antimicrobials (adjusted rate ratio, 1·20, 95% CI 0·70-2·05, p=0·51) or the rate of typhoid antimicrobials prescribed (0·93, 0·44-1·96, p=0·85). Unsafe water sources and insufficient diagnostic services were reported to contribute to the continued disease burden and antimicrobial prescription. INTERPRETATION: Non-specific febrile illness caused by confirmed or suspected typhoid is a common cause of antimicrobial use in endemic areas. Although effective in preventing typhoid fever, we were unable to identify any effect of Typbar-TCV on antimicrobial prescribing. Ethnographic research showed the effect of contextual factors on antimicrobial prescribing, including concerns regarding safe water access, appropriate sewage disposal, health-care and diagnostic availability. To realise effects beyond disease burden reduction, holistic approaches addressing these concerns are needed so that the value of vaccines mitigating the effects of antimicrobial use as a driver of antimicrobial resistance is fully achieved.

RESUMO

STUDY GOALS: To describe the differences between clients presenting after rape and clients who have consented to sex as a minor to an SGBV clinic in Harare, Zimbabwe, and how these differences affect their care requirements. BACKGROUND: Adolescents and adults presenting at the specialized Sexual and Gender Based Violence clinic in Harare are offered a standardised package of free medical and psychosocial care. Zimbabwe has an HIV prevalence of 14%, so prevention of HIV infection using PEP for those that present within 72 hours is a key part of the response. STI treatment, emergency contraceptive pills, referral for termination of pregnancy, psychological, social and legal support is also provided. METHODS: This is a retrospective descriptive study of routine programmatic data collected at the Edith Opperman polyclinic in Mbare SGBV clinic from 2011 to 2014. Chi-square tests and logistic regression were used to describe the different experiences and the differences in uptake of care between clients presenting for rape compared to those who consented to sex as a minor. RESULTS: During the study period a total of 3617 clients presented to the clinic. 2242 (62%) sought care after rape, 602 (17%) for having consented to sex as a minor and 395 (11%) for suspected sexual abuse. 1615 (45%) of people presenting were 12-15 year olds. Minors who consented to sex compared to survivors of rape were less likely to report within 72 hours- 156 (26%) vs 894 (40%) p<0.001; less likely to report that they delayed due to fear- 68 (17%) vs 472 (40%) p<0.001, less likely to have experienced accompanying violence- 9 (1%) vs 176 (8%) p<0.001 or physical trauma-34 (6%) vs 427 (19%) p<0.001; and less likely to display psychological symptoms at presentation 51 (8%) vs 411 (18%) p<0.001. Minors who consented to sex compared to those who were raped were less likely to start PEP if eligible-123 (80%) vs 751 (93%) p<0.001, less likely to take emergency contraceptives if eligible-125 (81%) vs 598 (88%) p<0.001, more likely to be pregnant- 132 (23%) vs 241 (15%) p<0.001; less likely to request a termination of pregnancy if pregnant-10 (8%) vs 74 (31%) p<0.001; and less likely to come for at least one follow up 281 (47%) vs 1304 (58%) p<0.001. CONCLUSION: The experiences of those who consent to sex as a minor and those that have experienced forced sex were very different. The standardised SGBV medical response does not fully meet the needs to protect minors who have consented to sex from HIV or unwanted pregnancies. Clients who present for having consented to sex as a minor might benefit more from being offered long-term family planning or being assessed as a sero-discordant couple rather than simply PEP and ECP as is relevant for clients who have been raped. More provision of health care is needed for minors to ensure they have access to enough information and protection from HIV, other STIs and unwanted pregnancy, before they decide to engage in sexual intercourse, rather than as an emergency at an SGBV clinic.
