  Abstract Background: Pastoralists rely on traditional healers (THs) for general health problems. However, some studies indicate that such practices result in delays in the diagnosis and treatment of tuberculosis (TB) cases. This study aims to assess the role of traditional healers in the detection and referral of active TB cases in a pastoralist community. Methods: We identified 22 traditional healers from 7 villages of Kereyu pastoralist community in the Fentale district in Ethiopia in January 2015. We trained these THs in identifying presumptive TB symptoms and early referral to the nearby healthcare facilities. The training was held during a 1 week period that included a visit to their villages and follow-up. A 1 day meeting was held with the traditional healers, the district TB care and prevention coordinator and health extension workers from the selected sub-district to discuss the referral link between THs and the nearby healthcare facilities. Health providers working at the TB units in the selected healthcare facilities were oriented about the training given and planned involvement of THs in referring presumptive TB case. In addition, documentation of the presumptive TB cases was discussed. Results: We succeeded in tracing and interviewing 8 of the 22 THs. The rest were on seasonal migration. According to the THs report for the 1 year period, these 8 THs had referred 24 TB suspects to the healthcare facilities. Sputum smear microscopy confirmed 13 of the 24 suspects as having TB cases. Among those confirmed, 10 completed treatment and three were on treatment. Five presumptive TB cases were confirmed non TB cases through further evaluation at the healthcare facilities and six of the presumptive TB cases were lost to follow up by the THs. Whereas, four of the presumptive TB cases were lost to follow up to the healthcare facility. Conclusions: Results of the present study indicate that THs can contribute to the detection of undiagnosed active TB cases in a pastoralist community, provided they are given appropriate training and support.

  Objective: The emerging and recent 2014 Ebola Virus Disease (EVD) outbreaks rang the bell to call upon efforts from globe to assist resource-constrained countries to strengthen public health surveillance system for early response. Malawi adopted the Integrated Disease Surveillance and Response (IDSR) strategy to develop its national surveillance system since 2002 and revised its guideline to fulfill the International Health Regulation (IHR) requirements in 2014. This study aimed to understand the state of IDSR implementation and differences between guideline and practice for future disease surveillance system strengthening. Methods: This was a mixed-method observational study. Quantitative data were to analyze completeness and timeliness of surveillance system performance from national District Health Information System 2 (DHIS2). Qualitative data were collected through interviews with 29 frontline health service providers from the selected district and key informants of the IDSR system implementation and administration at district and national levels. Findings: The current IDSR system showed relatively good completeness (76.4%) but poor timeliness (41.5%) of total expected monthly reports nationwide and zero weekly reports. The challenges of IDSR implementation revealed through qualitative data included lack of supervision, inadequate resources for training and difficulty to implement weekly report due to overwhelming paperwork at frontline health services. Conclusions: The differences between IDSR technical guideline and actual practice were huge. The developing information technology infrastructure in Malawi and emerging mobile health (mHealth) technology can be opportunities for the country to overcome these challenges and improve surveillance system to have better timeliness for the outbreaks and unusual events detection.

  Background Tuberculosis (TB) is a major public health concern in the developing world. Early diagnosis and prompt initiation of treatment is essential for effective TB control. The aim of this study was to determine the length and analyze associated factors of patients’ and health system’s delays in the diagnosis and treatment of new pulmonary TB (PTB) patients. Methods A cross-sectional study was conducted in 30 randomly selected public health facilities in West Gojjam Zone, Amhara Region, Ethiopia. Newly diagnosed PTB patients who were ≥15 years of age were consecutively enrolled in the study. Patients’ delay (the time period from onset of TB symptoms to first presentation to a formal health provider) and health system’s delay (the time period from first presentation to a formal health provider to first start of TB treatment) were measured. Median patients’ and health system’s delays were calculated. Mixed effect logistic regression was used to analyze predictors of patients’ and health system’s delays. Results Seven hundred six patients were enrolled in the study. The median patients’ delay was 18 days (interquartile range [IQR]: 8–34 days) and the median health system’s delay was 22 days (IQR: 4–88 days). Poor knowledge of TB (adjusted odds ratio [AOR], 2.33; 95 % confidence interval [CI], 1.34–4.05), first visit to non-formal health provider (AOR, 47.56; 95 % CI, 26.31–85.99), self-treatment (AOR, 10.11; 95 % CI, 4.53–22.56) and patients’ age (≥45 years) (AOR, 2.99; 95 % CI, 1.14–7.81) were independent predictors of patients’ delay. Smear-negative TB (AOR, 1.88; 95 % CI, 1.32–2.68) and first visit to public health centers (AOR, 2.22; 95 % CI, 1.52–3.25) and health posts (AOR, 5.86; 95 % CI, 1.40–24.39) were found to be independent predictors of health system’s delay. Conclusions The health system’s delay in this study was long and contributed more than 50 % of the total delay. Better TB diagnostic tools to complement sputum smear microscopy are needed to early diagnose PTB cases at peripheral health facilities. In addition, due emphasis should be given to increase public awareness about symptoms and consequences of TB disease.

  Background delay in diagnosis and treatment of tuberculosis (TB) may worsen the disease, increase mortality and enhance transmission in the community. This study aimed at assessing the association between total delay and unfavorable treatment outcome among newly diagnosed pulmonary TB (PTB) patients. Methods A prospective cohort study was conducted in West Gojjam Zone, Amhara Region of Ethiopia from October 2013 to May 2015. Newly diagnosed PTB patients who were ≥15 years of age were consecutively enrolled in the study from 30 randomly selected public health facilities. Total delay (the time period from onset of TB symptoms to first start of anti-TB treatment) was measured. Median total delay was calculated. Mixed effect logistics regression was used to analyze factors associated with unfavorable treatment outcome. Results Seven hundred six patients were enrolled in the study. The median total delay was 60 days. Patients with total delay of > 60 days were more likely to have unfavorable TB treatment outcome than patients with total delay of ≤ 60 days (adjusted odds ratio [AOR], 2.33; 95% confidence interval [CI], 1.04–5.26). Human immunodeficiency virus (HIV) positive TB patients were 8.46 times more likely to experience unfavorable treatment outcome than HIV negative TB patients (AOR, 8.46; 95% CI, 3.14–22.79). Conclusions Long total delay and TB/HIV coinfection were associated with unfavorable treatment outcome. Targeted interventions that can reduce delay in diagnosis and treatment of TB, and early comprehensive management of TB/HIV coinfection are needed to reduce increased risk of unfavorable treatment outcome.

  There is growing evidence showing the potential of T-cell-based gamma interferon (IFN-g) release assays (IGRAs) for predicting the risk of progression of Mycobacterium tuberculosis (Mtb) infection, though there is little information from tuberculosis (TB)-endemic settings. In this study, we assessed the association between the level of IFN-g produced by T cells in response to Mtb-specific antigens and the size of skin test indurations in 505 adult individuals who were screened for latent tuberculosis infection (LTBI) using the QuantiFERON-TB Gold In Tube (QFTGIT) assay and tuberculin skin test (TST). There was a strong positive correlation between the level of IFN-g induced by the specific antigens and the diameter of the skin indurations (Spearman’s rho 5 0.6, P < 0.001). Body mass index and parasitic infection were not associated with the level of IFN-g production or the TST reaction. In linear regression analysis, the size of the skin test indurations was significantly associated with the mean level of IFN-g [coefficient, 0.65; 95% confidence interval (CI), 0.47 to 0.82, P < 0.001]. Similarly, results from logistic regression analysis demonstrated that individuals who had skin test indurations ‡ 10 mm were 6.82 times more likely than individuals who had skin test indurations < 10 mm to have high levels of IFN-g (i.e. positive QFTGIT result) (adjusted odd ratio 5 6.82; 95% CI, 3.67 to 12.69, P < 0.001). In conclusion, the results of this study could provide indirect evidence for the prognostic use of the QFTGIT assay for progression of Mtb infection, though prospective follow-up studies are needed to provide direct evidence.

  This paper discusses outcome of studying challenges and opportunities of integrating Health Information System. The study was conducted in the settings of Primary Health Care programs in Northern State, Sudan. Qualitative case study was employed and data were collected through interviews, analysis of relevant documents, and observation of the settings. The results were analyzed using interpretive approach. The study findings indicated that fragmentation of Primary Health Care programs’ Information System is a major problem affecting system performance. Our study also showed that efforts to integrate Primary Health Care programs’ Information System might be challenged by the existing structural, socio-cultural and political contexts of the organization. On the other hand, opportunities for integration of the programs’ Information System lie in the existence of Health Information Center, which receives collected health data from all parts of the state and formulate common reports. Besides, most of the study participants were expressing optimism at outcomes of Information System integration. The need of considering structural, socio-cultural and political contexts of the organization is emphasised in order to address the identified challenges related to integrating Health Information Systems.

  Background: To investigate how the risk of active tuberculosis disease is influenced by time since original infection and to determine whether the risk of reactivation of tuberculosis increases or decreases with age. Methods: Cohort analysis of data for the separate ten year birth cohorts of 1876-1885 to 1959-1968 obtained from Statistics Norway and the National Tuberculosis Registry. These data were used to calculate the rates and the changes in the rates of bacillary (or active) tuberculosis. Data on bacillary tuberculosis for adult (20+) age groups were obtained from the National Tuberculosis Registry and Statistics Norway from 1946 to 1974. Most cases during this period arose due to reactivation of remote infection. Participants in this part of the analysis were all reported active tuberculosis cases in Norway from 1946 to 1974 as recorded in the National Tuberculosis Registry. Results: Tuberculosis decreased at a relatively steady rate when following individual birth cohorts, but with a tendency of slower decline as time passed since infection. A mean estimate of this rate of decline was 57 % in a 10 year period. Conclusions: The risk of reactivation of latent tuberculosis decreases with age. This decline may reflect the rate at which latent tuberculosis is eliminated from a population with minimal transmission of tubercle bacilli. A model for risk of developing active tuberculosis as a function of time since infection shows that the rate at which tuberculosis can be eliminated from a society can be quite substantial if new infections are effectively prevented. The findings clearly indicate that preventative measures against transmission of tuberculosis will be the most effective. These results also suggest that the total population harbouring live tubercle bacilli and consequently the future projection for increased incidence of tuberculosis in the world is probably overestimated.

  Aims: The aim of this paper is to explore experiences of being diagnosed with tuberculosis (TB) among immigrants in Norway, with a view to factors associated with diagnostic delay. Methods: A qualitative study was conducted among 22 participants diagnosed with TB who originated from Somalia or Ethiopia. Results: One-third of the participants reported less than 2 months from onset of symptoms to treatment were initiated. The factors associated with little delay included a medical history that gave suspicion of TB, presenting with typical TB symptoms, or being screened for TB at arrival. Two-thirds of the participants told about extensive diagnostic processes. Persistent cough not accompanied by symptoms such as: weight loss and weakness; mild, diffuse, atypical, and/or intermittent symptoms; and a sense of not being a likely victim of TB could delay patients’ first initiative to seek help. Participants experienced that the diagnostic process in the health services could endure for months, even years. The diagnosis could be difficult to confirm, but health professionals appeared to have difficulties with associating their symptoms with TB. This resulted in delays in initiating diagnostic tests for TB, especially in cases of extra-pulmonary TB. Conclusions: Public health efforts to increase awareness about TB transmission, its diversity in manifestations, and its progression from latent to active disease, may decrease patient delay. An increased awareness among health professionals about typical and atypical symptoms of TB, aspects of the patient’s history, and being aware and sensitive to patients’ own interpretation of symptoms may reduce diagnostic delay in the health services.
