BackgroundAssessment of delays in seeking care and diagnosis of tuberculosis is essential to evaluate effectiveness of tuberculosis control programs, and identify programmatic impediments. Thus, this review of studies aimed to examine the extent of patient, health system, and total delays in diagnosis of pulmonary tuberculosis in low- and middle- income countries.MethodsIt was done following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. Electronic databases were searched to retrieve studies published from 2007 to 2015 including Pubmed central, Springer link, Hinari and Google scholar. Searching terms were pulmonary tuberculosis, health care seeking, health care seeking behavior, patient delay, diagnostic delay, health system delay, provider delay, and doctor delay. Retrieved studies were systematically reviewed and summarized using Comprehensive Meta-analysis software.ResultsForty studies involving 18,975 patients qualified for systematic review, and 14 of them qualified for meta-analysis. The median diagnostic delay ranged from 30 to 366.5 days [IQR = 44–77.8], with a 4–199 days [IQR = 15–50] and 2–128.5 days [IQR = 12–34] due to patient and health system delays, respectively. The meta-analysis showed 42% of pulmonary tuberculosis patients delayed seeking care by a month or more; uneducated patients [pooled OR = 1.5, 95%CI = 1.1–1.9] and those who sought initial care from informal providers [pooled OR = 3, 95%CI = 2.3–3.9] had higher odds of patient delay.ConclusionDelay in diagnosis is still a major challenge of tuberculosis control and prevention programs in low- and middle- income settings. Efforts to develop new strategies for better case-finding using the existing systems and improving patients’ care seeking behavior need to be intensified.

BackgroundTo accelerate the expansion of primary healthcare coverage, the Ethiopian government started deploying specially trained community health workers named Health Extension Workers (HEWs) in 2003. HEWs work on sixteen health service packages; one being tuberculosis (TB) control and prevention. However, their contribution to TB care and prevention services among pastoralist communities has not been evaluated. Thus, this study has assessed their contribution in identification of persons with presumptive pulmonary TB in Ethiopian Somali Pastoralist Region.MethodA cross sectional study with mixed approach of quantitative and qualitative methods was applied. A randomly selected cross-sectional sample of 380 pulmonary TB cases from 20 health facilities was selected to obtain information on the role of HEWs in the identification of persons with presumptive TB, and their referral. Purposively selected HEWs were also interviewed individually to obtain in-depth information on their in-service training and experiences with referring TB cases. SPSS version20 was used to summarize the quantitative data and test statistical significance using chi-square test and logistic regression model. The qualitative data was analyzed under the principles of thematic analysis.ResultOverall, 20.3% [95% CI = 16.6–24.5] of pulmonary TB patients were referred by HEWs; while the majority were referred by healthcare workers (52.6%), family members (13.4%), neighbours/friends (2.4%) and self-referred (11.3%). Out of all, 66.1% and 53.4% had neither received community TB health education nor home visit from HEW respectively. Multivariate analysis indicated that provision of community health education [AOR = 14.0, 95% CI = 6.6–29.5], being model household [AOR = 21.2, 95% CI = 9.5–47.3], home visit from HEW [AOR = 2.8, 95% CI = 1.2–9.6] and rural residence [AOR = 3.0, 95% CI = 1.2–7.7] were significantly associated with referral by HEW. The qualitative findings supported that HEWs’ involvement in referral of persons with presumptive TB was limited. Communities’ low confidence in HEWs, inaccessibility of TB services at nearest health centers and lack of in-service trainings for HEWs were identified by the interviewee HEWs as underlying factors for their limited involvement.ConclusionThe contribution of health extension workers in identifying and referring presumptive TB cases is limited in Ethiopian Somali pastoralist region. Increased community health education and home visits by HEWs could contribute to increased identification and referral of persons with presumed TB. HEW should be properly trained on TB through in-service refreshment trainings and supported by routine supervision. Further expansion of TB diagnostic services would benefit to increasing case detection.

BackgroundThe prevalence of underfive diarrhea in Somali Regional State, Ethiopia is one of the highest in the country. This study attempted to examine the multiple factors associated with underfive diarrhea and how they might influence its prevalence in Jigjiga, Somali regional state, Ethiopia.MethodsA community based cross-sectional study was conducted from February 15 to 28, 2015. Multistage sampling technique was used to collect data from 492 mothers via household survey. A pre-tested, structured questionnaire was used to collect data through face-to-face interview. Ethical clearance was obtained before data collection. Stepwise multivariable logistic regression was used to calculate adjusted odds ratios.ResultsThe two weeks prevalence of under five diarrhea in Jigjiga town was 14.6%. Up on multivariable analysis, maternal educational level of primary school and above was found to be protective against childhood diarrhea [AOR: 0.227(0.100–0.517)] whereas, unavailability of water [AOR: 2.124(1.231–3.664)] and lack of hand washing facility [AOR: 1.846(1.013–3.362)] were associated with diarrhea.ConclusionPoor water supply, lack of hand washing facilities and lack of formal maternal education were associated with underfive diarrhea in the study area. Improved access to water supply along with environmental health intervention programs designed to promote good hygiene behavior could be of paramount importance to alleviate burden of childhood diarrhea.Electronic supplementary materialThe online version of this article (doi:10.1186/s12887-017-0934-5) contains supplementary material, which is available to authorized users.

Background: Healthcare-seeking behavior is the basis to ensure early diagnosis and treatment of tuberculosis (TB) in settings where most cases are diagnosed upon self-presentation to health facilities. Yet, many patients seek delayed healthcare. Thus, we aimed to identify the determinants of patient delay in diagnosis of pulmonary TB in Somali pastoralist area, Ethiopia. Methods: A matched case-control study was conducted between December 2017 and October 2018. Cases were self-presented and newly diagnosed pulmonary TB patients aged ≥ 15 years who delayed > 30 days without healthcare provider consultation, and controls were patients with similar inclusion criteria but who consulted a healthcare provider within 30 days of illness; 216 cases sex-matched with 226 controls were interviewed using a pre-tested questionnaire. Hierarchical analysis was done using conditional logistic regression. Results: After multilevel analysis, pastoralism, rural residence, poor knowledge of TB symptoms and expectation of self-healing were individual-related determinants. Mild-disease and manifesting a single symptom were disease-related, and >1 h walking distance to nearest facility and care-seeking from traditional/religious healers were health system-related determinants of patient delay > 30 days [p < 0.05]. Conclusion: Expansion of TB services, mobile screening services, and arming community figures to identify and link presumptive cases can be effective strategies to improve case detection in pastoral settings.
