Loss to follow up after pregnancy among mothers enrolled on the option B+ program in Uganda.

OBJECTIVE

Option-B+ programs in Uganda have reported high levels of loss to follow up (LTFU) after cessation of breastfeeding, and this remains unknown beyond this period. In this study, we assessed the incidence and factors associated with LTFU two to four years after delivery among Option-B+ mothers.

STUDY DESIGN

Retrospective cohort

METHODS

We reviewed files of 452 mothers who enrolled on Option-B+ between January 1st, 2013 and December 31st, 2014 ​at Kisenyi Health Centre IV in Kampala district. We assessed factors associated with LTFU using Cox proportional hazards regression. We also explored the reasons for LTFU using three focus group discussions, five in-depth and three key informant interviews.

RESULTS

Of the 452 mothers, 131(29%) were LTFU after delivery. The incidence of LTFU after delivery was 17/1000 person months (95% CI, 14-30/1000) with a median follow up of 32 months. The risk of LTFU was higher among mothers who started ART on the day they tested HIV positive (aHR ​= ​1.66, 95% CI; 1.25-2.20, p-value< 0.001). Reasons for LFTU included transport costs, stigma, poor human resource policies and non-disclosure.

CONCLUSION

LTFU after delivery among Option-B+ mothers is higher than the global target of 15%. ART initiation on the day a mother tests positive increases the risk of LTFU. The major reasons for LTFU were stigma and non-disclosure. To reduce the risk of LTFU, we recommend approaches that encourage disclosure to sexual partners and ongoing specific support to mothers who are initiated on ART-the day of positive test.
