  1. Sustaining quality while scaling up adolescent ARTFindings from Zimbabwe’s largest adolescent cohort Shroufi A, Dixon M, Gunguwo H, Nyathi M, Ndlovu M, Saint-Sauveur JF, Taziwa F, Ndebele W, Ferreyra C, Carmen Viñoles M

  2. Adolescents in need of ARTA growing challenge • Improved treatment means children with HIV are surviving longer • This means that increasing numbers of adolescents in Southern African are in need of ART 1 • Less experience managing this age group • Adolescents usually managed in adult programmes • Adult programmes may not address specific needs of adolescents 1. Ferrand et al. AIDS. 2009;23(15):2039-46.

  3. Will services cope?Adolescents pose particular challenges • Known challenges in managing chronic disease1 • More unhealthy / high risk behaviours2 • Poor adherence to ART previously documented3 • Sub-optimal virological responses documented4,5 • Present to services relatively late6 • Sawyer et al. Lancet. 2007;369(9571):1481-9. • Catalano et al. Lancet. 2012;379(9826):1653-64. • Murphy et al. AIDS Care. 2001;13(1):27-40. • Flynn et al.

  4. Will services cope? • Limited evidence on outcomes in Southern Africa • Can scale up be achieved successfully? 1. Bakanda et al. PloS one. 2011;6(4):e19261 2. Nglazi et al. BMC Infect Dis. 2012;12:21.

  5. Mpilo ART clinic BulawayoAdolescents were a challenge... • Zimbabwe pop: 12.5 million HIV prevalence: 13.1% (2010) • One of 1st OI ART sites in Zimbabwe. MSF has supported ART provision at Mpilo since it opened in 2004 • As adolescent numbers increased, management challenges arose.

  6. Adolescent model of care • Adolescent clinic located in separate space from adult & paediatric clinics • Specifically tailored services: • Dedicated, highly trained counsellors • Life skills training • Social activities, camp outside clinic • Youth club, “Chill Room” • Defaulter tracing • Peer counselling • Adolescents engaged in clinic management decisions through elected peer representatives An adolescent counsellor counselling an adolescent at Mpilo Hospital in Bulawayo (Written consent for use provided)

  7. Adolescent model of care “Chill” Room • Psychosocial Support: • Life skills support, pottery, income generating projects, expressing feelings and thoughts through art, Hero book (MMPZ) • All Mpilo Clinic staff was trained in adolescent customer care

  8. Scale up of ART Initiation > 7 fold increase in initiations > 3 fold increase in initiations

  9. Methods • Retrospective cohort study, 2004 - 2010 • Data electronically recorded after patient consultations • Cox proportional hazards model used • Age defined at time of ART initiation: Adolescents 10-19, adults ≥ 19 • LFU: appointment missed by ≥ 3 months • Compared adolescent and adult outcomes

  10. OutcomesMore adolescents initiated late and ill *Statistically significant

  11. Adolescent outcomes maintained during scale up • Adolescents • No change in deaths over time • HR = 0.92*, p=0.59 • No change in LFU over time • HR=1.02*, p=0.59 • Adults • No change in deaths over time • HR=0.9*, p=0.131 • Increase in LFU over time • HR=1.2*, p=0.004 *Adjusted for age, haemoglobin, CD4 and BMI.

  12. Mortality and LFUAdolescent LFU lower than in adults P=0.83 P<0.0001

  13. Summary FindingsMuch adolescent HIV undiagnosed + untreated • Diagnosis usually after clinical illness, consistent with estimates that 75% of adolescent HIV is undiagnosed1 • By the end of study period, 17% of all actively followed patients were adolescents (1,610 / 9,387*) compared to estimate of 5% nationally1 1. Ferrand et al. Bull World Health Organ. 2010;88(6):428-34

  14. Summary FindingsGood retention and low LFU can be achieved • Despite challenges, low LFU and high retention were achieved in adolescents • Despite later presentation, survival in adolescents equalled adult survival

  15. Conclusions • As more HIV positive children survive into adolescence, scale-up of specific services is needed • Need to increase case-finding efforts by incorporating innovative approaches to identify HIV-positive adolescents, then link them to care tailored to their needs. • Good adolescent results are feasible with dedicated services in resource-constrained settings

  16. Acknowledgements • We acknowledge the work of all patients, MoHCW and MSF staff at Mpilo OI ART clinic • We also acknowledge the work of Million Memory Project Zimbabwe (MMPZ) • And the Contact Counselling Trust of Bulawayo Conflict of Interest • The authors declare that they have no conflicts of interest

  17. Supplementary information

  18. Death rates + LFU ratesCrude and adjusted for LFU At the most plausible levels of death among those lost to follow up no difference in death rates between groups

  19. Results

  20. Entry to ART servicesFew adolescents came from VCT services Most adolescents referred from hospital after becoming unwell, subsequently being offered provider initiated testing and counselling (PITC)

  21. Regimen infoMost common regimens used at initiation

  22. ResultsMore adolescents initiated late *30% of those lost to follow up assumed to have died
