Qualitative exploration of perceived benefits of care and barriers influencing HIV care in trans Nzoia, Kenya.

BACKGROUND: Substantial efforts have been made to ensure people living with HIV (PLHIV) are linked to and retained in care but many challenges deter care utilization. We report perceived benefits of seeking HIV care and barriers to HIV care that were identified through a formative assessment conducted to advise the development of an alternative care model to deliver antiretroviral treatment therapy (ART) in Trans Nzoia County, Kenya. METHODS: Data were collected in 2015 through key informant interviews (KIIs), in-depth interviews (IDIs), and focus group discussions (FGDs). The study involved 55 participants of whom 53% were female. Ten KIIs provided community contextual information and viewpoints on the HIV epidemic in Trans Nzoia County while 20 PLHIV (10 male and 10 female) participated in IDIs. Twenty-five individuals living with HIV participated in four FGDs - two groups for men and two for women. Key informants were purposively selected, while every third patient above 18 years at the Kitale HIV Clinic was invited to share their HIV care experience through IDIs or FGDs. Trained research assistants moderated all sessions and audio recordings were transcribed and analyzed thematically. RESULTS: Findings showed that PLHIV in Trans Nzoia County used both conventional and complementary alternative care for HIV; however, public health facilities were preferred. Popular perceived benefits of adopting care were relief from symptoms and the chance to live longer. Benefits of care uptake included weight gain, renewed energy, and positive behavior change. Individual-level barriers to HIV care included lack of money and food, use of alternative care, negative side effects of ART, denial, and disclosure difficulties. At the community level, stigma, limited social support for conventional HIV treatment, and poor means of transport were reported. The health system barriers were limited supplies and staff, long distance to conventional HIV care, and unprofessional providers. CONCLUSIONS: Diverse individual, community and health system barriers continue to affect HIV care-seeking efforts in Kenya. Appreciation of context and lived experiences allows for development of realistic care models.

PREVALENCE, TREATMENT AND CONTROL OF HYPERTENSION AMONG TYPE 2 DIABETIC PATIENTS AT MOI TEACHING AND REFERRAL HOSPITAL, ELDORET, KENYA.

OBJECTIVES: To describe the prevalence, treatment and control of hypertension among type 2 diabetic patients at Moi Teaching and Referral Hospital (MTRH) and to determine predictors of blood pressure (BP) control. DESIGN: A cross-sectional study. SETTING: Diabetic Outpatient Clinic at MTRH, Eldoret, Kenya. SUBJECTS: Type 2 diabetic patients. INTERVENTIONS: The study collected socio-demographic (age, gender, employment status, monthly income, education level, marital status, cigarette smoking and alcohol use), clinical (BP, weight, height and waist circumference) and laboratory (serum fasting lipids and creatinine, urine proteins) data from type 2 diabetic patients. Good BP control was defined as < 130mmHg systolic and < 80mmHg diastolic. Association between BP control and social demographic, clinical and laboratory variables of study subjects was determined using the chi-square, T-test, fisher's exact test and logistic regression. RESULTS: We studied 218 type 2 diabetics: mean age 57 ± 9 years; 122 (56%) were females. Average duration of diabetes was 11 ± 7 years. Prevalence of hypertension was 185/218 (85%) out of who 40 (21%) had good BP control. Average duration of hypertension was 7 ± 5 years. Of the 185 hypertensive diabetics: 92 (50%) had total cholesterol at goal; 102 (55%) had low density lipoproteins (LDL) at goal; 74 (40%) had triglycerides at goal; 65 (35%) had high density lipoprotein (HDL) at goal and 85(45%) had Proteinuria. All hypertensive patients had > 1 anti-hypertensive agent prescribed. Good BP control was associated with compliance to anti-hypertensives (OR = 0.342, 95% CI: 0.105- 1.432) and having HDL at goal (OR = 0.247, 95% CI: 0.126-0.845). Poor BP control was associated with a higher number of prescribed anti-hypertensive agents (OR = 1.377, 95% CI: 1.112- 2.302). CONCLUSION: Prevalence of hypertension among type 2 diabetic patients in MTRH is high and BP control is poor despite anti-hypertensive treatment. Significant predictors of BP control include compliance to anti-hypertensives and control of HDL.

Symptom screen: diagnostic usefulness in detecting pulmonary tuberculosis in HIV-infected pregnant women in Kenya.

OBJECTIVE: To determine the diagnostic usefulness of tuberculosis (TB) symptom screening to detect active pulmonary TB among human immunodeficiency virus (HIV) infected pregnant women in two PMTCT (prevention of mother-to-child transmission) clinics in western Kenya that are supported by the United States Agency for International Development-Academic Model Providing Access to Healthcare partnership. DESIGN: Cross-sectional study. Participants were interviewed for TB symptoms with a standardized questionnaire (cough >2 weeks, fever, night sweats, weight loss or failure to gain weight). Those with cough submitted sputum specimens for smear microscopy for acid-fast bacilli and mycobacterial culture. Women at >14 weeks gestation underwent shielded chest radiography (CXR). RESULTS: Of 187 HIV-infected women, 38 (20%) were symptom screen-positive. Of these, 21 had a cough for >2 weeks, but all had negative sputum smears and mycobacterial cultures. CXRs were performed in 26 symptomatic women: three were suggestive of TB (1 miliary, 1 infiltrates and 1 cavitary). Of 149 women with a negative symptom screen, 100 had a CXR and seven had a CXR suggestive of TB (1 cavitary, 2 miliary and 4 infiltrates). CONCLUSION: This study did not support the utility of isolated symptom screening in identification of TB disease in our PMTCT setting. CXR was useful in identification of TB suspects in both symptomatic and asymptomatic women.

Task shifting in HIV clinics, Western Kenya.

BACKGROUND: United states Agency for International development-Academic Model for Providing Accesses to Healthcare (USAID-AMPATH) cares for over 80,000 HIV-infected patients. Express care (EC) model addresses challenges of: clinically stable patient's adherent to combined-antiretroviral-therapy with minimal need for clinician intervention and high risk patients newly initiated on cART with CD4 counts < or = 100 cells/mm3 with frequent need for clinician intervention. OBJECTIVE: To improve patient outcomes without increasing clinic resources. DESIGN: A descriptive study of a clinician supervised shared nurse model. SETTING: USAID-AMPATH clinics, Western Kenya. RESULTS: Four thousand eight hundred and twenty four patients were seen during the pilot period, 90.4% were eligible for EC of whom 34.6% were enrolled. Nurses performed all traditional roles and attended to two thirds and three quarters of stable and high risk patient visits respectively. Clinicians attended to one third and one quarter of stable and high risk patient visits respectively and all visits ineligible for express care. CONCLUSION: The EC model is feasible. Task shifting allowed stable patients to receive visits with nurses, while clinicians had more time to concentrate on patients that were new as well as more acutely ill patients.

Risk factors for death in HIV-infected adult African patients receiving anti-retroviral therapy.

OBJECTIVE: To determine risk factors for death in HIV-infected African patients on anti-retroviral therapy (ART). DESIGN: Retrospective Case-control study. SETTING: The MOH-USAID-AMPATH Partnership ambulatory HIV-care clinics in western Kenya. RESULTS: Between November 2001 and December 2005 demographic, clinical and laboratory data from 527 deceased and 1054 living patients receiving ART were compared to determine independent risk factors for death. Median age at ART initiation was 38 versus 36 years for the deceased and living patients respectively (p<0.0148). Median time from enrollment at AMPATH to initiation of ART was two weeks for both groups while median time on ART was eight weeks for the deceased and fourty two weeks for the living (p<0.0001). Patients with CD4 cell counts <100/mm3 were more likely to die than those with counts >100/mm3 (HR=1.553. 95% CI (1.156, 2.087), p<0.003). Patients attending rural clinics had threefold higher risk of dying compared to patients attending clinic at a tertiary referral hospital (p<0.0001). Two years after initiating treatment fifty percent of non-adherent patients were alive compared to 75% of adherent patients. Male gender, WHO Stage and haemoglobin level <10 grams% were associated with time to death while age, marital status, educational level, employment status and weight were not. CONCLUSION: Profoundly immunosuppressed patients were more likely to die early in the course of treatment. Also, patients receiving care in rural clinics were at greater risk of dying than those receiving care in the tertiary referral hospital.

Admission characteristics, diagnoses and outcomes of HIV-infected patients registered in an ambulatory HIV-care programme in western Kenya.

OBJECTIVE: To determine admissions diagnosis and outcomes of HIV-infected patients attending AMPATH ambulatory HIV-care clinics. DESIGN: Prospective cohort study. SETTING: Academic Model for Prevention and Treatment of HIV/ AIDS (AMPATH) ambulatory HIV-care clinic in western Kenya. RESULTS: Between January 2005 and December 2006, 495 HIV-infected patients enrolled in AMPATH were admitted. Median age at admission was 38 years (range: 19-74), 62% females, 375 (76%) initiated cART a median 56 days (range: 1-1288) before admission. Majority (53%) had pre-admission CD4 counts <100 cells/ml and 23% had counts >200 cells/ml. Common admissions diagnoses were: tuberculosis (27%); pneumonia (15%); meningitis (11%); diarrhoea (11%); malaria (6%); severe anaemia (4%); and toxoplasmosis (3%). Deaths occurred in 147 (30%) patients who enrolled at AMPATH a median 44 days (range: 1-711) before admission and died a median 41 days (range: 1-713) after initiating cART. Tuberculosis (27%) and meningitis (14%) were the most common diagnoses in the deceased. Median admission duration was six days (range: 1-30) for deceased patients and eight days (range: 1-44) for survivors (P=0.0024). Deceased patients enrolled in AMPATH or initiated cART more recently, had lower CD4 counts and were more frequently lost to follow-up than survivors (P<0.05 for each comparison). Initiation of cART before admission and clinic appointment adherence were independent predictors of survival. CONCLUSION: Although high mortality rate is seen in HIV-infected in-patients, those initiating cART before admission were more likely to survive.

Characteristics of HIV infected patients cared for at "academic model for the prevention and treatment of HIV/AIDS" clinics in western Kenya.

BACKGROUND: With the new initiatives to treat large numbers of HIV infected individuals in sub-Saharan Africa, policy makers require accurate estimates of the numbers and characteristics of patients likely to seek treatment in these countries. OBJECTIVE: To describe characteristics of adults receiving care in two Kenyan public HIV clinics. DESIGN: Cross-sectional cohort analysis of data extracted from an electronic medical records system. SETTING: Academic Model for the Prevention and Treatment of HIV/AIDS (AMPATH) HIV clinics in Kenya's second national referral (urban) hospital and a nearby rural health center. SUBJECTS: Adult patients presenting for care at HIV clinics. MAIN OUTCOME MEASURES: Gender and inter-clinic stratified comparisons of demographic, clinical, and treatment data. RESULTS: In the first nineteen months, 790 adults visited the urban clinic and 294 the rural clinic. Mean age was 36 +/- 9 (SD) years. Two-thirds were women; a quarter had spouses who had died of acquired immune deficiency syndrome (AIDS). HIV/AIDS behavioural risk factors (multiple sexual partners, rare condom use) and constitutional symptoms (fatigue, weight loss, cough, fever, chills) were common. Rural patients had more symptoms and less prior and current tuberculosis. Men more commonly presented with symptoms than women. The cohort CD4 count was low (223 +/- 197 mm3), with men having significantly lower CD4 count than women (185 +/- 175 vs. 242 +/- 205 p = 0.0007). Eighteen percent had an infiltrate on chest radiograph. Five percent (most often men) had received prior antiretroviral drug therapy, (7% in urban and 1% in rural patients, p = 0.0006). Overall, 393 (36%) received antiretroviral drugs, 89% the combination of lamivudine, stavudine, and nevirapine. Half received prophylaxis for tuberculosis and Pneumocystis jirovecii. Men were sicker and more often received antiretroviral drugs. CONCLUSIONS: Patients presenting to two Kenyan HIV clinics were predominantly female, ill and naive to retroviral therapy with substantial differences by clinic site and gender. Behavioural risk factors for HIV/AIDS were common. A thorough understanding of clinical and behavioural characteristics can help target prevention and treatment strategies.

Bronchoscopic study on aetiology of chronic cough in HIV-infected adults with negative sputum smears for Mycobacterium tuberculosis at Kenyatta National Hospital, Nairobi.

OBJECTIVE: To establish the aetiology of chronic cough in HIV-infected patients with negative sputum smears for Acid Fast Bacilli (AFB). DESIGN: A cross-sectional descriptive study. SETTING: Kenyatta National Hospital, a tertiary referral centre in Kenya SUBJECTS: Sixty five HIV-infected adults presenting with chronic cough and negative sputum smears for AFBs. RESULTS: Sixty-two patients were included in the final analysis. Aetiology of chronic cough was established in 42 (68%) patients. Pneumocystis jiroveci, bacterial pneumonia and Mycobacterium tuberculosis were diagnosed in 22 (35.5%), 17 (27.4%) and 14 (22.5%) patients respectively. Majority (98%) of patients with a diagnosis had multiple causes established in them. Ciprofloxacin had activity against 91% of the isolated organisms while Penicillin was active against 35% only. CONCLUSION: This study documents Pneumocystis jiroveci pneumonia as a common cause of morbidity in a subset of HIV infected patients with chronic cough and negative sputum smears for AFB in Kenya.
