Patient satisfaction with TB care clinical consultations in Kampala: a cross sectional study.

BACKGROUND: Patient satisfaction towards care during encounter with clinicians is key for better treatment outcomes. We assessed patient satisfaction with TB clinical care consultations in Kampala, Uganda. METHODS: This was a facility-based cross sectional study done between September 2012 and February 2013 using qualitative method of data collection. Participants consecutively completed a pre-tested structured satisfaction questionnaire. A criteria of the rating as good; >75% was considered acceptable, (50-75%) as more effort is needed and <50 as unacceptable and require immediate action was used to categorize data for analysis using Epi-info 7.1.4.0. RESULTS: Of the 260 registered TB patients, 178(68.5%) completed the questionnaire. Overall, 162 (91.0%) were satisfied with the clinical consultation. Factors that contributed to high patient satisfaction, were: time spent with clinician (85.4%), explanation of what was done (87.6%), technical skills (91.6%), personal manner of the clinician seen (91.6%). Factors for low satisfaction were; waiting time before getting an appointment (61.8%), convenience of location of consultation office (53.4%), getting through to the office by phone (21.3%) and length of time waiting at the office (61.2%). CONCLUSION: Tuberculosis patients in Kampala are satisfied with TB clinical care consultations. Addressing factors with low patient satisfaction may significantly impact on treatment outcome.

Tuberculosis risk factors among tuberculosis patients in Kampala, Uganda: implications for tuberculosis control.

BACKGROUND: Slow decline in the incidence of tuberculosis (TB) has been observed in most high TB burden countries. Knowledge of the prevalence of different TB risk factors can help expand TB control strategies. However with the exception of Human Immunodeficiency Virus (HIV) the prevalence of the other TB risk factors are poorly studied in Uganda. We aimed to determine the prevalence of different TB risk factors and TB disease presentation among TB patients in Kampala Uganda. METHODS: We assessed 365 adult TB patients and used descriptive statistics to summarize their socio-demographic, clinical, radiological, sputum mycobacteriology and TB risk factors (HIV, diabetes, TB contact, alcohol use, tobacco smoking, poverty and overcrowding) data. RESULTS: A total of 158 (43.3%) patients were male and the median age was 29 (IQR 28-30). Majority of the patients (89.2%) had pulmonary TB, 86.9% were new and 13.2% were retreatment. Wasting (i.e. body mass index of <18.5 kg/m(2)) was found in 38.5% of the patients and 63% presented with cough. Constitutional symptoms (fever, anorexia, night sweats and weight loss) were reported by 32.1%. Most patients (78.6%) presented with non-cavity lung parenchyma disease (infiltrates, nodules, masses) but 35.2% had cavity disease. Pleural disease was detected in 19.3% of patients. Positive smear microscopy and culture (irrespective of month of treatment) was found in 52.7% and 36.5% of patients respectively. Any drug resistance was detected in 21.1% of patients while multidrug resistance (MDR) TB defined as resistance to rifampicin and isoniazid was detected in 6.3% of patients. All MDR patients were new patients. The prevalence of TB risk factors were as follows: HIV 41.4%, diabetes 5.4%, close contact 11.5%, family history 17.5%, smoking 26.37%, poverty 39.5%, overcrowding 57.3% and alcohol use 50.7%. Overcrowding increased smear positive rate, prevalence ratio 1.22, p = 0.09 but all the other studied risk factors did not affect clinical, radiological and mycobacteriological study patient characteristics. CONCLUSIONS: Among TB patients in Kampala, Uganda, there is high prevalence of the known TB risk factors. Targeting reducing their prevalence may lead to better TB control in the country.

Early versus delayed initiation of highly active antiretroviral therapy for HIV-positive adults with newly diagnosed pulmonary tuberculosis (TB-HAART): a prospective, international, randomised, placebo-controlled trial.

BACKGROUND: WHO guidelines recommend early initiation of antiretroviral therapy (ART) irrespective of CD4 cell count for all patients with tuberculosis who also have HIV, but evidence supporting this approach is poor quality. We assessed the effect of timing of ART initiation on tuberculosis treatment outcomes for HIV-positive patients with CD4 counts of 220 cells per µL or more. METHODS: We did this randomised, placebo-controlled trial between Jan 1, 2008, and April 31, 2013 at 26 treatment centres in South Africa, Tanzania, Uganda, and Zambia. We enrolled HIV-positive patients with culture-confirmed tuberculosis who had tolerated 2 weeks of tuberculosis short course chemotherapy. Participants were randomly allocated (1:1) to early ART (starting after 2 weeks of tuberculosis treatment) or delayed ART (placebo, then starting ART at the end of 6 months of tuberculosis treatment). Randomisation was computer generated, with permuted blocks of size eight, and stratified by CD4 count (220-349 cells per µL vs ≥350 cells per µL). Patients and investigators were masked to treatment allocation until completion of 6-months' tuberculosis treatment, after which the study was open label. The primary endpoint was a composite of failure of tuberculosis treatment, tuberculosis recurrence, and death within 12 months of starting tuberculosis treatment in the modified intention-to-treat population. Secondary endpoints included mortality. The study is registered with controlled-trials.com (ISRCTN77861053). FINDINGS: We screened 13,588 patients and enrolled 1675: 834 assigned early ART, 841 delayed ART. The primary endpoint was reached by 65 (8·5%) of 767 patients in the early ART group versus 71 (9·2%) of 771 in the delayed ART group (relative risk [RR] 0·91, 95% CI 0·64-1·30; p=0·9). Of patients with a CD4 cell count of 220-349 cells per µL, 26 (7·9%) of 331 patients versus 33 (9·6%) of 342 reached the primary endpoint (RR 0·80, 95% CI 0·46-1·39; p=0·6). For those with 350 cells per µL or more, 39 (8·9%) of 436 versus 38 (8·9%) of 429 reached the primary endpoint (RR 1·01, 95% CI 0·63-1·62; p=0·4). Mortality did not differ significantly between treatment groups (RR 1·4, 95% CI 0·8-2·3; p=0·23). Grade 3 and 4 adverse events occurred in 149 (18%) of 834 patients assigned early ART versus 174 (21%) of 841 assigned delayed ART (p=0·37). 87 (10%) of 834 versus 84 (10%) of 841 had immune reconstitution inflammatory syndrome (p=0·56). INTERPRETATION: ART can be delayed until after completion of 6 months of tuberculosis treatment for HIV-positive patients with tuberculosis who have CD4 cell counts greater than 220 cells per µL. WHO guidelines should be updated accordingly. FUNDING: USAID, Zambia Ministry of Health, Tanzania Commission for Science and Technology, WHO-TDR.

Advances in the Diagnosis, Treatment and Control of HIV Associated Tuberculosis.

There has been an increase in the number of published tuberculosis/HIV (TB/HIV) research findings in recent times. The potential impact of these findings on routine care has informed this review which aims at discussing current concepts and practices underpinning TB/HIV care and control. Any HIV infected person with a cough of any duration is currently considered a TB suspect. Preliminary results also show that the diagnostic yield of same day sputum samples (front loading) is comparable to two-day samples. Laboratory diagnosis is shifting from Ziehl-Neelsen (ZN) smear microscopy and solid culture to fluorescent microscopy, molecular tests and liquid culture. Concomitant TB/HIV therapy improves survival and WHO has recommended ART for all TB/HIV patients. Unless CD4 cell counts are less than 50 cells/µl, ART can be deferred until end of intensive phase. Evidence of survival benefit at high CD4 cell counts is still lacking. New TB drugs and treatment shortening studies are underway but so far no new TB drugs has been added to the current arsenal and treatment duration still remains six months or more. WHO has recommended the 31s (intensified TB case finding, isoniazid prophylaxis and infection control) for TB/HIV control in addition to effective therapy, Antiretroviral therapy and TB vaccines. There has been immense progress in TB/HIV research, however optimal management of HIV-Infected TB patients, will require further research and appropriate translation of emerging evidence to policy and practice.

A randomised placebo-controlled safety and acceptability trial of PRO 2000 vaginal microbicide gel in sexually active women in Uganda.

OBJECTIVES: To determine the safety of 0.5% and 2% PRO 2000 gel in terms of local and systemic adverse events (AE) and the acceptability of gel use. DESIGN: A randomised placebo-controlled trial among healthy, sexually active African women aged 18-45 years. Between June 2003 and September 2004, 180 consenting women were randomly assigned to one of four groups: PRO 2000 gel (0.5% or 2%), placebo gel, or condom use only. Participants were screened for sexually transmitted infections, with HIV counselling and testing. Women randomly assigned to gel used this intravaginally twice a day for 28 days. Follow-up visits were fortnightly up to 6 weeks from enrolment, and comprised a physical examination including colposcopy, laboratory testing and questionnaire interviews. RESULTS: Ten women were lost to follow-up, none due to AE. Adherence with total gel doses was 69%. Observed rates of the primary toxicity endpoints, ulceration greater than 2 x 1 cm and clinically relevant coagulation abnormalities were, for PRO 2000 0.5%: 1.6% (95% CI 0.04% to 8.5%) and 0% (97.5% CI 0% to 5.7%), and for PRO 2000 2%: 0% and 0% (97.5% CI 0% to 5.9%). Women randomly assigned to active gels did not show an increased rate of AE. Gel use had no significant effect on haematology and biochemistry results. Women found gel use highly acceptable. CONCLUSIONS: Both concentrations of PRO 2000 gel were found to be safe and well tolerated. These data justified testing the gels in large-scale effectiveness trials.
