Characteristics of HIV-infected children seen in Western Kenya.

OBJECTIVES: To describe the characteristics and outcomes of children registered for care in a large HIV care programme in Western Kenya. DESIGN: A retrospective descriptive study. SETTING: USAID-AMPATH HIV clinics in health centres; district and sub-district hospitals; Moi Teaching and Referral Hospital in Western Kenya. SUBJECTS: HIV-infected children below age of 15 years seen in a network of 18 clinics in Western Kenya. INTERVENTIONS: Paediatric HIV diagnosis and care including treatment and prevention of opportunistic infections and provision of combination antiretroviral therapy (CART). MAIN OUTCOME MEASURES: Diagnosis, clinical stage and immune status at enrollment and follow-up; hospitalisation and death. Descriptive statistical analyses and chi square tests were performed. RESULTS: Four thousand and seventeen HIV-infected children seen between June 2002 and April 2008. Median age at enrollment was four years (0-14.2 years), 51% girls, 25% paternal orphans, 10% total orphans and 13% maternal orphans. At enrollment, 25% had weight-for-Age Z scores (WAZ) > or = -1 and 21% had WAZ scores < or = 3. Orphaned children had worse WAZ scores (p=0.0001). Twenty five per cent of children were classified as WHO clinical stage 3 and 4, 56% were WHO clinical stages 1 and 2 with 19% missing clinical staging at enrollment. Cough (25%), gastroenteritis (21%), fever (15%), pneumonia (10%) were the commonest presenting features. Twenty six per cent had been diagnosed with tuberculosis and only 25% started on cotrimoxazole preventive therapy (CPT). Median CD4% at enrollment was 16% (0-64%); latest recorded values were 22% (0-64). Sixty four per cent were on cART (cART+), median age at start was 5.4 (014.4 years). The median initial CD4% among cART+ was 13 (0-62) compared to 24 (0-64) for those not on ART (cART-). Median CD4% for cART+ improved to 22% (0-59); whereas cART- was 23% (0-64) at last appointment. During the period of follow-up, one fifth (19%) of children on cART were lost to follow-up compared to slightly over one third (37%) for those not on cART. Thirty four percent were hospitalised; 41% diagnosed with pneumonia. Six per cent of 4017 were confirmed dead. CONCLUSIONS: HIV-infected children were enrolled in care early in childhood. Orphanhood was prevalent in these children as were gastroenteritis, fever, pneumonia and advanced immuno-suppression. Orphans were more likely to be severely malnourished. Only a quarter of children were put on cotrimoxazole preventive therapy. Children commenced on cART late but responded well to treatment. Loss to follow-up was less prevalent among those on cART.

'Triangulating' AMPATH: demonstration of a multi-perspective strategic programme evaluation method.

Clinical programmes are typically evaluated on operational performance metrics of cost, quality and outcomes. Measures of patient satisfaction are used to assess the experience of receiving care, but other perspectives, including those of staff and communities, are not often sought or used to assess and improve programmes. For strategic planning, the Kenyan HIV/AIDS programme AMPATH (Academic Model Providing Access to Healthcare) sought to evaluate its performance in 2006. The method used for this evaluation was termed 'triangulation', because it used information from three different sources--patients, communities, and programme staff. From January to August 2006, Indiana University external evaluators and AMPATH staff gathered information on strengths, weaknesses and suggestions for improvement of AMPATH. Activities included in-depth key-informant semi-structured interviews of 26 AMPATH clinical and support staff, 56 patients at eight clinic sites, and seven village health dialogues (mabaraza) at five sublocations within the AMPATH catchment area. Data sources included field notes and transcripts of translated audio recordings, which were subjected to qualitative content analysis. Eighteen recommendations for programme improvement emerged, including ten from all three respondent perspectives. Three recommendations were cited by patients and in mabaraza, but not by staff. Triangulation uncovered improvement emphases that an internal assessment would miss. AMPATH and Kenyan Ministry of Health leadership have deliberated these recommendations and accelerated strategic change actions, including rural satellite programmes, collaboration with village-based workers, and door-to-door village-based screening and counselling.

Nasopharyngeal Streptococcus pneumoniae among under-five year old children at the Moi Teaching and Referral Hospital, Eldoret, Kenya.

OBJECTIVES: To determine the prevalence, risk factors and antibiotic sensitivity of streptococcus pneumoniae carried in the upper respiratory tract of children. DESIGN: A cross-sectional study on consecutive clients. SETTING: Maternal Child Health Clinic (MCH) at Moi Teaching and Referral Hospital (MTRH) in western Kenya. SUBJECTS: Seventy eight of children attending Maternal Child Health Clinic between March 10th 2003 and July 11th 2003. MAIN OUTCOME MEASURES: Upper airway carriage status, ventilation, housing, age, illness, sensitivity patterns. RESULTS: Fifty six percent were boys; the median age was six months (range 1-42 months). Streptococcus pneumoniae carriage rate was in 28 (35.9%) cases. Fifty two percent of S. pneumoniae were resistant to penicillin, 25% to ampicillin and 78% to cotrimoxazole. There was significant association between the type of floor with pneumococcal carriage (p = 0.009) with people living in earth floor houses being five times more likely to be pneumococcal carriers as compared to those living in cement floor houses. CONCLUSIONS: A significant resistance of S. pneumoniae to penicillin, ampicillin and cotrimoxazole was found. Earth floored houses may increase susceptibility to upper airway S. pneumoniae carriage. RECOMMENDATION: Similar studies should be conducted in other parts of Kenya in order to learn about susceptibility patterns and associated risk factors, including floor type, in the country and tailor better treatment regimens.
