Background

• Pediatric HIV care has been implemented predominantly in secondary and tertiary level facilities because of lack of pediatric expertise and limited human resources

• Decentralization of HIV care to primary health facilities is considered the cornerstone of HIV treatment scale-up

• Conflicting reports of ART effectiveness between primary and secondary/tertiary health care facilities**Fatti, et al. PLoS 2010, Bock, et al. Trans R Soc Trop Med Hyg,2008,

Boyer et al. AIDS 2010, Massaquoi, et al. Trans R Soc Trop Med Hyg, 2009

Objectives

• Describe trends in pediatric enrollment in HIV care and ART initiation at primary health facilities (PHFs) and secondary/tertiary health facilities (SHFs)

• Compare patient outcomes (lost to follow-up [LTFU] and mortality rates) between PHFs and SHFs

Methods (1)• Quarterly reported aggregate program data from 274

ICAP-supported public facilities in Kenya, Lesotho, Mozambique, Rwanda and Tanzania • PHFs (health centers or clinics)• SHFs (district, provincial, regional hospitals)

• Included children <15 years of age enrolled between January 2008 to March 2010

• Excluded data from:– Pediatric Centers of Excellence (n=6)– Private health facilities (n=20)– New facilities if < 1 year of data (n=136)

Methods (2)• Main Outcomes:

– Pediatric enrollment in HIV care and ART initiation– LTFU per 100 person-years (py) on ART – Mortality / 100 py on ART

• Covariates:– Facility type, program size, program maturity, CD4

machine on site, FTE nurses and clinicians, % children < 24mos, and country

• Statistical Analysis:— Univariate and multivariate analysis— Relative risk regression model and also accounted for

correlated data

Trend in Facilities (January 2008-March 2010)

• The number of ICAP supported facilities increased from 128 to 274 – PHFs increased 3-fold from 56 to 182

• 64% of the PHFs were rural– SHFs increased by 30% from 72 to 92

• 64% of the SHFs were urban

Pediatric Enrollment (January 2008- March 2010)

• A total of 17,155 children were enrolled in care and 8,475 initiated ART

• 10,901 (64%) of new pediatric enrollees and 6,032 (71%) of children initiating ART were at SHFs– SHFs accounted for only ⅓ of facilities supported

• A total of 4,948 children <24mos were enrolled in care– SHFs accounted for 3,069 (62%) in care and 1,510

(69%) on ART

Conclusion (1)• Over the 2 year period the number of ICAP

supported PHFs increased 3-fold resulting in 6,254 additional children enrolled in HIV care – This increase in number of PHFs resulted in an

increase in the proportion of children newly initiating ART at PHFs

• However, SHFs still account for majority of the children enrolled in care, and receiving antiretrovirals and the majority of infants initiating ART

Conclusion (2)• Lost to follow-up and mortality was

lower in PHFs compared to SHFs• PHFs play an important role in expanding

the capacity for the care of HIV-infected children

• Further research is needed to advance our understanding of the optimal models for delivering pediatric HIV care and treatment
