Nutritional status of HIV-infected women with tuberculosis in Dar es Salaam,Tanzania

Setting:

Tuberculosis (TB) treatment clinics in Dar es Salaam, Tanzania.

Objective:

To quantify anthropometrics and intake of en-ergy and protein among human immunodeficiency virus (HIV) positive women with TB.

Design:

HIV-positive women with newly diagnosed TB were assessed on their anthropometric characteristics and dietary intake. Energy and protein intake were determined using Tanzania food composition tables and compared with standard recommendations. Patients were re-evaluated after 4–6 months of anti-tuberculosis treatment.

Results:

Among 43 women, the baseline median CD4 count was 209 cells/µl (range 8–721); 19 (44%) had a CD4 count of <200; 20 (47%) were on antiretroviral therapy. Body mass index was <18.5 kg/m² in 25 (58%); the median food insecurity score was 6. The median level of kcal/day was 1693 (range 1290–2633) compared to an estimated need of 2658; the median deficit was 875 kcal (range −65–1278). The median level of protein/day was 42 g (range 27–67) compared to 77 g estimated need; the median protein deficit was 35 g (range 10–50). The median weight gain among 29 patients after 4–6 months was 6 kg.

Conclusion:

HIV-positive women with TB have substantial 24-h deficits in energy and protein intake, report significant food insecurity and gain minimal weight on anti-tuberculosis treatment. Enhanced dietary education together with daily supplementation of 1000 kcal with 40 g protein may be required.     

Occupational health policies and practices related to tuberculosis in health care workers in KwaZulu-Natal,South Africa

Setting:

Three district hospitals in KwaZulu-Natal, South Africa, with specialized drug-resistant tuberculosis (TB) wards.

Objective:

To increase understanding of the implementation of occupational health (OH) and infection control (IC) guidelines for the prevention and control of TB among health care workers (HCWs).

Design:

An operational cross-sectional study conducted between July and September 2011, consisting of interviews with OH and IC nurses and chart review of OH medical records.

Results:

Although general national and provincial OH policies are in place, no specific OH policies exist for hospital settings. Two of three hospitals had a full-time OH nurse and all had a full-time IC nurse. All hospitals offered TB symptom screening; however, only 19% of HCWs were screened in 2010. TB incidence among HCWs was 1958 per 100 000 population in 2010. All hospitals offered HIV counseling and testing; however, only 22% of staff were tested across sites. Two hospitals offered isoniazid preventive therapy to HIV-positive staff and reassigned these staff to low TB risk areas.

Conclusions:

While OH policies and procedures are in place, implementation of these policies and procedures is inconsistent. This potentially places HCWs at risk of acquiring TB. These findings support the need for strengthening OH and IC services to prevent TB.     

医疗卫生机构医务人员结核病感染控制现状

目的分析我国医务人员结核感染和患病情况以及相应的危险因素,为加强医疗卫生机构医务人员的结核病感染预防控制工作提供理论依据。方法采取系统综述的方法,对1995-2010年关于医疗卫生机构中医务人员结核感染和患病情况及其影响因素的相关文献资料进行综合分析。结果我国关于医务人员结核感染预防控制方面的研究很欠缺。文献资料显示,我国医务人员的结核感染率明显高于普通人群,其PPD阳性率达60.4%～62.8%;医务人员的结核病患病率也比一般人群高,达6.7/1 000人年。对医务人员感染结核的危险因素分析显示,其结核感染和患病风险主要与在工作场所暴露和感染预防控制措施不足等有关。结论医务人员的结核感染控制工作十分薄弱,相关研究不足,目前已成为我国结核病控制面临的重要问题。     

Opportunities for community health workers to contribute to global efforts to end tuberculosis

ABSTRACT

Tuberculosis (TB) has emerged as the leading infectious cause of death globally. New paradigms are needed to reduce TB rates and mortality. Programs harnessing the potential of community health workers (CHWs) to enhance TB prevention and care have shown great promise. In this perspective article, we review the history of CHW-based efforts to prevent and treat TB, present evidence illustrating the effectiveness of CHWs across the entire cascade of TB care, and outline additional opportunities for CHWs to address challenges particular to the TB pandemic. Despite many promising studies, knowledge gaps persist and we suggest an agenda for future research on the role of CHWs in TB prevention and care.

Primary health care staff's perceptions of childhood tuberculosis: a qualitative study from Tanzania

Background  

Diagnosing tuberculosis in children remains a great challenge in developing countries. Health staff working in the front line of the health service delivery system has a major responsibility for timely identification and referral of suspected cases of childhood tuberculosis. This study explored primary health care staff's perception, challenges and needs pertaining to the identification of children with tuberculosis in Muheza district in Tanzania.     

Bank accounts for public primary health care facilities: Reflections on implementation from three districts in Tanzania

Health care financing reforms are gaining popularity in a number of African countries to increase financial resources and promote financial autonomy, particularly at peripheral health care facilities. The paper explores the establishment of facility bank accounts at public primary facilities in Tanzania, with the intention of informing other countries embarking on such reform of the lessons learned from its implementation process. A case study approach was used, in which three district councils were purposively sampled. A total of 34 focus group discussions and 14 in‐depth interviews were conducted. Thematic content analysis was used during analysis. The study revealed that the main use of bank account revenue was for the purchase of drugs, medical supplies, and minor facility needs. To ensure accountability for funds, health care facilities had to submit monthly reports of expenditures incurred. District managers also undertook quality control of facility infrastructure, which had been renovated using facility resources and purchases of facility needs. Facility autonomy in the use of revenue retained in their accounts would improve the availability of drugs and service delivery. The experienced process of opening facility bank accounts, managing, and using the funds highlights the need to strengthen the capacity of staff and health‐governing committees.     

Professionalism and the know‐do gap: exploring intrinsic motivation among health workers in Tanzania

Professionalism can be defined generally as adhering to the accepted standards of a profession and placing the interests of the public above the individual professional's immediate interests. In the field of medicine, professionalism should lead at least some practitioners in developing countries to effectively care for their patients despite the absence of extrinsic incentives to do so. In this study we examine the behavior of 80 practitioners from the Arusha region of Tanzania for evidence of professionalism. We show that about 20% of these practitioners behave professionally, and almost half of those who do so practice in the public sector. These professional health care workers provide high quality care even when they work in an environment that does not reward this effort, a finding that has important implications for the use of performance‐based incentives.

Social workers as care coordinators: Leaders in ensuring effective,compassionate care

The concept of care coordination is at the forefront of national conversations in the context of health care reform. As pediatric social workers, we are interested in how care coordination benefits our patients, and which disciplines are providing coordination services. We have determined that significant overlap exists between the work social workers are already doing in inpatient and outpatient medical settings and the literature’s definition of care coordination activities. This article outlines our process of literature review and creation of a working definition of care coordination, and frames the concepts we believe remain central to the process of care coordination.     

IPT coverage and determinants of care coverage in Tanzania

BACKGROUND:TB is a major cause of mortality worldwide, with the highest risk in people living with HIV/AIDS (PLWHA). Isoniazid preventive therapy (IPT), in combination with antiretroviral therapy (ART), reduces the overall incidence and mortality from TB by up to 90% among PLWHA. Tanzania has limited published data on IPT coverage among PLWHA.OBJECTIVE:To investigate coverage and determinants of IPT among PLWHA receiving care in selected care and treatment clinics in Dar es Salaam, Tanzania.METHODS:An analytical cross-sectional design to study 31,480 HIV-positive adults. Proportions and comparisons were obtained using χ² tests, while determinants for IPT were assessed using adjusted multivariable analysis.RESULTS:The IPT coverage among eligible PLWHA was generally low (28.9%), with increased coverage over time. The determinants for IPT coverage included age >36 years, having WHO Clinical Stages 1 and 2 compared to 3 and 4, and having normal weight, or being overweight and obesity compared to underweight.CONCLUSION:IPT coverage in Dar es Salaam is very low; individuals with minor HIV disease severity were more likely to initiate IPT. This shows a possible gap in the prescribing practices among healthcare providers. More efforts to ensure IPT coverage implementation in Dar es Salaam are required.     

Decentralization and health care prioritization process in Tanzania: from national rhetoric to local reality

During the 1990s, Tanzania like many other developing countries adopted health sector reforms. The most common policy change under the health sector reforms has been decentralization, which involves the transfer of power and authority from the central level to local authorities. Based on the case study of Mbarali district in Tanzania, this paper uses a policy analysis approach to analyse the implementation of decentralized health care priority setting. Specifically, the paper examines the process, actors and contextual factors shaping decentralized health care priority setting processes. The analysis and conclusion are based on a review of documents, key informant interviews, focus group discussion, and notes from non‐participant observation. The findings of the study indicate that local institutional contexts and power asymmetries among actors have a greater influence on the prioritization process at the local level than expected and intended. The paper underlines the essentially political character of the decentralization process and reiterates the need for policy analysts to pay attention to processes, institutional contexts, and the role of policy actors in shaping the implementation of the decentralization process at the district level.

Understanding informal payments in health care: motivation of health workers in Tanzania

Background  

There is growing evidence that informal payments for health care are fairly common in many low- and middle-income countries. Informal payments are reported to have a negative consequence on equity and quality of care; it has been suggested, however, that they may contribute to health worker motivation and retention. Given the significance of motivation and retention issues in human resources for health, a better understanding of the relationships between the two phenomena is needed. This study attempts to assess whether and in what ways informal payments occur in Kibaha, Tanzania. Moreover, it aims to assess how informal earnings might help boost health worker motivation and retention.     

Reflecting and shaping the discourse: The role of music in AIDS communication in Tanzania

Failure to recognize the importance of oral traditions in Africa and the potential of music and song for stimulating social and behavior change would represent a missed opportunity in HIV prevention strategies. Local narratives concerning AIDS are often utilized in popular songs and constitute rich sources of contextual information about the epidemic that have thus far been un- or underutilized in HIV prevention strategies. Endogenously conceived messages delivered via a channel such as music increase the likelihood of messages being contextually appropriate and culturally engaging. This form of media also presents the greatest opportunity for wide dissemination. Drawing on field work conducted in the Kilimanjaro region, this paper presents examples of how music and musicians in Tanzania reflect and potentially shape AIDS discourse. Three broad recurrent themes addressed in songs are discussed: AIDS metaphors, stigma and broader HIV prevention messages. By tapping into the wealth of information about AIDS discourse contained within popular songs, and by recognizing musicians as potential opinion leaders and agents of social change, the effectiveness of prevention strategies may be increased.

In-hospital contact investigation among health care workers after exposure to pulmonary tuberculosis in an intermediate tuberculosis prevalence area: A prospective study

We carried out in-hospital contact investigations of patients with pulmonary tuberculosis and analyzed the prevalence of latent tuberculosis infection (LTBI) among health care workers (HCWs) after TB exposure. A prospective study was conducted of 872 HCWs who were exposed to 55 index cases diagnosed with active pulmonary TB. HCWs after TB exposure were evaluated both TST and chest X-ray at the time of enrollment and 12 weeks after exposure; 625 HCWs (71.6%) underwent both initial assessments; 41 HCWs (6.6%) had a positive TST result. After 12 weeks, 71.1% of HCWs with initial negative TST (n = 415) underwent a second assessment. Ten HCWs had TST conversion. One HCW (0.2%) developed active pulmonary TB. In multivariable analysis, age over 30 years was associated with TST conversion (p = .02). Point prevalence of latent TB was 6.6%, and incidence of LTBI was estimated as 2.4 per 100 HCWs. Strict infection control measures should be emphasized in intermediate TB-burden, BCG-vaccinated countries, especially in HCWs with high risk for TB exposure.

Attitudes towards and perceptions of reproductive health needs of persons living with HIV/AIDS in rural Kilimanjaro,Tanzania

The introduction of antiretroviral treatment has resulted in the resumption of socially productive and sexually active lives of people living with HIV/AIDS, together with the desire for children. However, factors affecting the reproductive health needs of people living with HIV/AIDS are not well understood. With this in mind, the aim of this paper was to investigate factors associated with these health needs using a qualitative approach. Findings indicate that attitudes and perceptions about reproductive health needs are influenced by fertility beliefs, the central role of family, procreation and the perceived social and clinical consequences of pregnancies among people living with HIV/AIDS. While there was mixed opinion about acceptability of people living with HIV/AIDS, having children, marriage and family were institutions important for partnerships maintenance and procreation. These findings suggest that living with HIV in a community with strong pro-life attitudes is challenging for people living with HIV/AIDS who do not have children. Apart from having to grapple with potential stigma of not having children, people living with HIV/AIDS also face social challenges in realising their reproductive choices. Interventions to address stigma, societal changes and the integration of reproductive-health education into HIV care and treatment are needed.     

Improving motivation among primary health care workers in Tanzania: a health worker perspective

In Tanzania access to urban and rural primary health care is relatively widespread, yet there is evidence of considerable bypassing of services; questions have been raised about how to improve functionality.     

Impact of oral health education on primary school children before and after teachers' training in Tanzania

Oral health education is part of the primary school curriculumin Tanzania. However, most of the teachers responsible for itlack training and motivation for the task. Their oral healtheducation sessions are deficient in content and in methods,only addressing oral hygiene by lectures. Thus, modified oralhealth education was designed and teacher training workshopswere carried out in one district by a dental team in liaisonwith school administrators. After training, the teachers taughta variety of oral health issues and pupils actively studiedthe concepts and practical skills for dietary choices and toothbrushing.This report describes the impact of oral health education givenby teachers before and after they had been trained in the workshops.The impact of the sessions was assessed as changes in the pupils'oral health knowledge, attitudes and practices. Three randomsamples, each with 200 pupils, including conventional and modifiedsession groups and a reference group not given oral health educationat school, were interviewed and examined. The group that receivedmodified oral health education had better knowledge of oralhealth, reported reduced consumption of sugary foods and increasedtoothbrushing frequency, and had better ‘mswaki’(chewing-stick) making skills and slightly improved oral hygiene;in comparison with the referents. The group with conventionaloral health education had some what better oral health knowledgebut their practices were no better than the referents'. Theresults emphasize the need for providing training, guidanceand feedback to implementors of oral health education programmes.
