Program Background  Family AIDS Care and Education Services (FACES) Family-focused program Collaboration between Kenya Medical Research Institute (KEMRI) and University of California, San Francisco (UCSF) Operational since September 2004 in Nyanza and Nairobi  FACES program areas Provider Initiated Testing and Counseling (PITC) Prevention of Mother to Child Transmission (PMTCT) HIV Care and Treatment Voluntary Male Medical Circumcision (VMMC)

Background  The Kenya National Guidelines on Antiretroviral Therapy (ART), guided by WHO guidelines, has rapidly evolved  Latest changes effected in September 2010 CD4 cut off of ≤250 cells/uL increased to ≤350 cells/uL WHO stage 4 broadened to both stage 3 and 4

When to start consortium Lancet,2009

Introduction

Study Objective  To determine the effect of the new guidelines on the proportion of patients initiating ART at a large clinic in Western Kenya

Lumumba HIV clinic

Study Methods  Retrospective cohort study at Lumumba Health Centre, Kisumu Adult patients ≥ 18 years Initiated on HAART prior to (October April 2010) and after change in guideline (October April 2011) Each patient followed up for one year Clinical outcomes followed for one year  Data abstraction from Open MRS and patient charts - demographic and clinical data  Chi-square and Wilcoxon-Mann-Whitney tests conducted for analysis

Results VariablesPrePostP-value Proportion initiating HAART13.2% (N=866) 25.3% (N=846) P<0.001 Median 6 months CD4 increase (cells/uL) P<0.001 Median 12 months CD4 increase (cells/uL) P<0.001 LTFU (≥ 3 months after the appointment) 23.7%14.1 %P= 0.003

Results  No difference in Median age in the two groups 32.5 vs 32 years  WHO Stage 2 was more common before guidelines changed (34.2%)  WHO Stage 1 was the most common stage following guideline change (39%; p=0.03)

Conclusion The latest change in the guidelines led to:  A higher proportion of the newly enrolled patients initiated on ART  Initiation at earlier/healthier WHO stage  Greater increase in median CD4 cell count at 6- months  Interestingly, there were fewer lost to follow- up patients with new guidelines
