Knowledge, awareness and use of HIV services among the youth from nomadic and agricultural communities in Tanzania.

BACKGROUND: Nomadic life not only prevents the community from accessing and utilising HIV services but also deters them from obtaining reliable information on HIV. METHODS: We conducted a cross-sectional study of youth aged 10-24 years from the Kilindi and Ngorongoro Districts in Tanzania to assess knowledge, accessibility and utilisation of HIV/AIDS services among nomadic and agricultural youths. RESULTS: Of 518 youths interviewed, 279 (53.9%) were males, and 276 (53.3%) were from agricultural communities. A significant proportion of youths from agricultural communities had correct knowledge of AIDS (n = 126, 45.8%; P = 0.002), HIV transmission (n = 273, 98.9%; P = 0.001) and comprehensive knowledge of HIV/AIDS (n = 78, 28.5%; P = 0.009) compared to nomads. Youths from agricultural communities were two times (OR 1.8, 95% CI 1.2-2.6) more likely to be aware of the availability of formal HIV services. Awareness of the availability of HIV services was higher among married individuals than in unmarried ones (OR 3.8, 95% CI 2.0-7.4), and significantly higher among youths with secondary/college education than in those who did not have formal education (OR 5.3, 95% CI 2.3-12.4). The uptake of HIV services was lower among nomadic youths. CONCLUSION: Knowledge, awareness and utilisation of HIV/AIDS transmission services were low in general, and even lower among nomadic youths, calling for more targeted interventions.

CONTEXTE: La vie nomade n'entrave pas seulement l'accès et l'utilisation des services VIH par une communauté mais empêche également l'accès à une information VIH fiable. MÉTHODES: Nous avons réalisé une étude transversale auprès de jeunes de 10­24 ans des districts de Kilindi et de Ngorongoro en Tanzanie pour évaluer les connaissances, l'accessibilité et l'utilisation des services VIH/SIDA parmi les jeunes nomades et agriculteurs. RÉSULTATS: Sur 518 jeunes, 279 (53,9%) étaient des garçons, 276 (53,3%) venaient de communautés agricoles. Une proportion significative des jeunes de communautés agricoles avaient des connaissances correctes en matière de SIDA (n = 126 ; 45,8% ; P = 0,002), de transmission du VIH (n = 273 ; 98,9% ; P = 0,001) de connaissances complètes du VIH/SIDA (n = 78 ; 28,5% ; P = 0,009) comparées à celles des nomades. Les jeunes des communautés agricoles étaient deux fois plus au courant (OR 1,8 ; IC 95% 1,2­2,6) de la disponibilité de services VIH formels. La connaissance de la disponibilité de services VIH était plus élevée chez les jeunes mariés (OR 3,8 ; IC 95% 2,0­7,4) comparés aux célibataires, et significativement plus élevée parmi les jeunes ayant eu une instruction secondaire/supérieure comparés à ceux qui n'avaient eu aucune éducation formelle (OR 5,3 ; IC 95% 2,3­12,4). L'utilisation des services VIH était plus faible parmi les nomades. CONCLUSION: Les connaissances, la sensibilisation et l'utilisation des services de transmission du VIH/SIDA étaient bas et encore plus bas chez les jeunes nomades, appelant des interventions plus ciblées.

Capacity of healthcare facilities in the implementation of direct observed treatment strategy for tuberculosis in Arumeru and Karatu districts, Tanzania.

Directly Observed Treatment Short course strategy (DOTS) has proved to have potential improvement in tuberculosis (TB) control in Tanzania. The objective of this cross sectional study was to assess the capacity of health facilities in implementing DOTS, in Arumeru and Karatu districts, Tanzania. Information sought included the capacity to offer TB service and availability of qualified staff and equipment for TB diagnosis. Information on availability and utilization of TB registers and treatment outcome for the year 2004 were also collected. A total of 111 health facilities were surveyed, 86 (77.5%) in Arumeru and 25 (22.5%) in Karatu. Only 23.4% (26/111) facilities were offering TB treatment services in the two districts. Majority 17/26 (65.38%) of them were government owned. Thirty eight (44.7%) facilities were offering TB laboratory services. All facilities with TB services (TB laboratory investigation and treatment) had TB registers. Seventy two (85.0%) of health facilities which do not provide any TB services had qualified clinical officers and at least a microscopy. Of the 339 cases notified in Arumeru in 2004, 187 (60.7%) had treatment outcome available, 124 (66.3%) were cured and 55 (29.4%) completed treatment. In Karatu 638 cases were notified in 2004, 305 (47.8%) had treatment outcome available, 68 (22.3%) cured and 165 (54.1%) completed treatment. In conclusion, the overall capacity for implementing DOTS among the facilities surveyed is found only in about 20% and 30% for clinical and laboratory components of DOTS, respectively. The capacity to provide TB diagnosis and treatment in Karatu district was relatively lower than Arumeru. It is important that capacity of the facilities is strengthened concurrently with the planned introduction of community-based DOTS in Tanzania.

Dissatisfaction with the laboratory services in conducting HIV related testing among public and private medical personnel in Tanzania.

BACKGROUND: A comprehensive care and treatment program requires a well functioning laboratory services. We assessed satisfaction of medical personnel to the laboratory services to guide process of quality improvement of the services. METHODOLOGY: A cross-sectional survey in 24 randomly selected health facilities in Mainland Tanzania was conducted to assess the satisfaction of the medical personnel with the laboratory services. RESULTS: Of 235 medical personnel interviewed, 196 were valid for analysis and about one quarter were dissatisfied with the laboratory services. Personnel dissatisfied with the services were 38.3% in timely test result, 24.5% in correct and accurate results and 22.4% in clear complete results. The personnel in public laboratories were more dissatisfied with timely test results (OR = 3.6, 95% CI 1.8, 7.3), correct results (OR = 4.1, 95% CI 1.6, 10.8) and clear complete results (OR = 5.0 95% CI 1.6, 15.2). Personnel dissatisfied with the services in 15 laboratories sending specimens to referral laboratories, varied from 13% in availability of equipment to 57% in timely results feedback from the referral laboratories. Personnel dissatisfied with the services in 14 referral laboratories, varied from 28.6% in properly identified specimen to 42.9% in clear, accurate test request and communication. CONCLUSION: About one quarter of medical personnel in sending or receiving laboratories were dissatisfied with the services. Comparing the personnel in public and private, the personnel in public laboratories were 4 times more dissatisfied with the timely test and correct results; and 5 times more dissatisfied with clear and complete test results.

Patient's dissatisfaction with the public and private laboratory services in conducting HIV related testing in Tanzania.

BACKGROUND: Patient's satisfaction with both private and public laboratory services is important for the improvement of the health care delivery in any country. METHODS: A cross-sectional survey was conducted in 24 randomly selected health facilities with laboratories that are conducting HIV related testing, in Mainland Tanzania. The study assessed patient's satisfaction with the laboratory services where by a total of 295 patients were interviewed. RESULTS: Of data analyzed for a varying totals from 224 to 294 patients, the percentage of dissatisfaction with both public and private laboratory services, ranged from 4.3% to 34.8%, with most of variables being more than 15%. Patients who sought private laboratory services were less dissatisfied with the cleanness (3/72, 4.2%) and the privacy (10/72, 13.9%) than those sought public laboratory service for the same services of cleanness (41/222, 18.5%) and privacy (61/222, 27.5%), and proportional differences were statistically significant (X2 = 8.7, p = 0.003 and X2 = 5.5, p = 0.01, respectively). Patients with higher education were more likely to be dissatisfied with privacy (OR = 1.8, 95% CI: 1.1-3.1) and waiting time (OR = 2.5, 95% CI: 1.5 - 4.2) in both private and public facilities. Patients with secondary education were more likely to be dissatisfied with the waiting time (OR = 5.2; 95%CI: 2.2-12.2) and result notification (OR = 5.1 95%CI (2.2-12.2) than those with lower education. CONCLUSION: About 15.0% to 34.8% of patients were not satisfied with waiting time, privacy, results notification cleanness and timely instructions. Patients visited private facilities were less dissatisfied with cleanness and privacy of laboratory services than those visited public facilities. Patients with higher education were more likely to be dissatisfied with privacy and waiting time in both private and public facilities.

The quality of sputum smear microscopy diagnosis of pulmonary tuberculosis in Dar es Salaam, Tanzania.

This study was carried out to determine the rate of agreement or disagreement of microscopy reading and culture positivity rate among smear positixe and negative specimens between peripheral tuberculosis diagnostic centres (PDCs) and Central Reference luberculosis laboratory (CTRL). In this study 13 PDCs in Dar es Salaam, Tanzania were involved. Lot Quality Assurance Sampling (LQAS) method was used to collect 222 sputum smear slides. A total of 190 morning sputum specimens with corresponding slides were selected for culture. First readings were done by technicians at PDCs and thereafter selected slides and specimens were sent to CTRL for re-examination and culture. Culture results were used as a gold standard. Of 222 slides selected, 214 were suitable for re-examination. Percentage of agreement of smear reading between PDCs and CTRL was 42.9% and 100% for positive and negative slides, respectively. Measure of agreement (Kappa statistic) was 0.5, indicating moderate agreement. Of 190 samples cultured, percentage of agreement between smear reading from PDCs and CTRL was 37% and 88.9% for smear positive and negative slides, respectively. Kappa statistic was 0.3 indicating poor-fair agreements. Comparison of smear reading from PDCs with culture showed sensitivity of 36.9% and specificity of 88.9%. Comparison of smear readings from CTRL with culture results showed sensitivity of 95.6% and specificity of 98.6%. In conclusion there was inadequate performance in diagnosis of TB using smear microscopy among peripheral diagnostic centres in Dar es Salaam. This calls for immediate and rigorous measures to improve the quality of smear microscopy. It is therefore important to strengthen the capacity of laboratory personnel in smear microscopy techniques through supportive supervision and training.

Quality of HIV laboratory testing in Tanzania: a situation analysis.

Tanzania is scaling up prevention, treatment, care and support of individuals affected with HIV. There is therefore a need for high quality and reliable HIV infection testing and AIDS staging. The objective of this study was to assess laboratories capacities of services in terms of HIV testing and quality control. A baseline survey was conducted from December 2004 to February 2005 in 12 laboratories which were conveniently selected to represent all the zones of Tanzania. The questionnaires comprised of questions on laboratory particulars, internal and external quality control for HIV testing and quality control of reagents. Source and level of customer satisfaction of HIV test kits supply was established. Of 12 laboratories, nine used rapid tests for screening and two used rapid tests for diagnosis. In the 12 laboratories, four used double ELISA and five used single ELISA and three did not use ELISA. Confirmatory tests observed were Western Blot in three laboratories, DNA PCR in two laboratories, CD4 counting in seven laboratories, and viral load in two laboratories. Although all laboratories conducted quality control (QC) of the HIV kits, only two laboratories had Standard Operating Procedures (SOPs). Internal and external quality control (EQC) was done at varied proportions with the highest frequency of 55.6% (5/9) for internal quality control (IQC) for rapid tests and EQC for ELISA, and the lowest frequency of 14.3% (1/ 7) for IQC for CD4 counting. None of the nine laboratories which conducted QC for reagents used for rapid tests and none of the five which performed IQC and EQC had SOPs. HIV kits were mainly procured by the Medical Store Department and most of laboratories were not satisfied with the delay in procurement procedures. Most of the laboratories used rapid tests only, while some used both rapid tests and ELISA method for HIV testing. In conclusion, the survey revealed inadequacy in Good Laboratory Practice and poor laboratory quality control process for HIV testing reagents, internal and external quality control.

The determination of safety of Muhanse M4, a traditional herbal preparation used to treat HIV/AIDS-related conditions and diseases in Tanzania.

Muhanse M4 is a traditional herbal preparation that has been in use in Tanzania for the past 17 years to improve the quality of life among people living with HIV/AIDS. This study was carried out to determine the safety of the extract Muhanse M4 in animal models. The qualitative test to identify alkaloids and saponins compounds was carried out. The toxicity tests in Swiss albino mice and rats were done according to WHO guidelines of 1993. Muhanse M4 was dissolved homogeneously in distilled water and was administered both intraperitonially and orally for 14 days for sub-acute test and 24 hours for acute test. Qualitatively, the extract was found to contain no alkaloids or saponins. In rats intraperitoneal doses that caused 100% lethality were 758.55 mg/kg and 553.7415mg/kg when administered singly and repeated, respectively. Single oral dose up to 3034.200mg/kg did not cause any death in the tested mice or rats. NOEL during intraperitoneal repeated doses for liver in rats was 424.788mg/kg, and NOAEL was 455.130mg/kg. In rats LD10%, LD50% and LD100% were 485.472mg/kg, 526.4337mg/kg and 553.7415mg/kg, respectively. In conclusion, Muhanse M4 extract is considered to be safe in laboratory animals.
