Pulmonary tuberculosis diagnostic delays in Chad: a multicenter, hospital-based survey in Ndjamena and Moundou

Tuberculosis treatment delay and contributing factors within tuberculosis patients in Ethiopia: A systematic review and meta-analysis

Background

Tuberculosis (TB) is a significant public health disease and a major contributor to illness and death worldwide, including in Ethiopia. There are many information from first source which had inconclusive result in Ethiopia. Therefore, this review aimed to produce pooled evidence on the TB treatment delay and factors associated with it.

Methods

The absence of a similar study with a systematic review and meta-analysis was confirmed. Articles from online available and unpublished sources conducted within Ethiopia between 2002 and 2024, were thoroughly screened using electronic sources such as Medline, Embase, Hinari, PubMed, the Cochrane Library, the Web of Science, and Google Scholar. Data analysis was performed using STATA version 14. Heterogeneity was assessed using Inverse of Variance (I2) and Cochrane Q tests. The funnel plot was employed to rule existence of publications subjectively while bias was checked using Egger's statistical method to quantify the bias.

Result

Prevalence of TB treatment delay in Ethiopia was 50.42% at 95% (43.21, 57.64). Factors such as knowledge about TB, distance to health facilities less than 10 km, initial contact at a government service providing center for TB, having some educations, having pulmonary Tuberculosis, urban residency, were prtotective towards treatment delay. Female in gender, no chest pain symptom, disease severity with no restriction on daily activity, alcohol drinkers, and unmarried respondents were at higher risk to miss on time tuberculosis treatment.

Conclusion and recommendation

The tuberculosis treatment delay in Ethiopia was considerably unexpected and basic personal variables and facility related variables were statistically associated with treatment. Therefore, Ethiopian TB control programs have to recognize and tackle the problem, obstacles, and vulnerability across the continuum patient care taking down and connecting to treatment post-diagnosis. This can be achieved by capacitating both government and non-governmental service provision centers and minimizing unfilled difference across professional awareness and skill, which will contribute further to minimizing delay.

Patient delay and health system delay of patients with newly diagnosed pulmonary tuberculosis in Mongolia, 2016-2017

Although diagnosis and treatment of tuberculosis (TB) have been improved in many countries, delays in the diagnosis and treatment remain problematic in resource-limited countries. This study aimed to identify factors affecting delays in TB care in Mongolia. Data on TB cases registered from January 2016 to December 2017 were obtained from the national registry of TB at the Department of TB Surveillance and Research in National Center for Communicable Disease. The total number of TB cases registered in these two years was 8,166, including 3,267 cases of newly diagnosed pulmonary TB. Pulmonary TB cases (1,836 males and 1,431 females) were analyzed to estimate adjusted odds ratios (aORs) and 95% confidence intervals (CIs). Patient delays longer than the median (28 days) were significantly associated with patient age >32 years (aOR=1.31, 95%CI: 1.14-1.51), residence in areas other than Ulaanbaatar (aimags) (aOR=1.38, 95%CI: 1.20-1.59), and smear-negative (aOR=0.57, 95%CI: 0.47-0.69). Health system delays longer than the median (7 days) were significantly associated with patient age >32 years (aOR=1.16, 95%CI: 1.00-1.33), residence in aimags (aOR=0.82, 95%CI: 0.71-0.95), special facilities including a prison hospital (aOR=4.40, 95%CI: 2.42-7.83), registration in 2017 relative to 2016 (aOR=0.83, 95%CI: 0.71-0.95), and smear-negative (aOR=1.72, 95%CI: 1.42-2.07). Total delays longer than the median (45 days) were significantly associated with patient age >32 years (aOR=1.39, 95%CI: 1.21-1.60), residence in aimags (aOR=1.27, 95%CI: 1.11-1.47), and smear-negative (aOR=0.74, 95%CI: 0.62-0.90). To shorten the total delay, improvement of the access to medical facilities in aimags is necessary.

Total, Patient and System Diagnostic Delays for Pulmonary Bacilliferous Tuberculosis in the Six Diagnostic and Treatment Centers in the Five Health Districts of the Central Region, Burkina Faso, 2018

Introduction

Long diagnosis delay contributes significantly to the failure to eradicate tuberculosis. The objective of this study was to evaluate the total, patient and system delays in diagnosis of pulmonary bacilliferous in the six tuberculosis Diagnostic and Treatment Centers in the five health districts of the central region in Burkina Faso.

Methods

A descriptive cross-sectional study was conducted among 384 microscopy-positive pulmonary tuberculosis patients in 2018 to address this objective. It concerned the socio-demographic, clinical, microbiological characteristics, and referral location/pathway characteristics of the patients. We then calculated the different delays. The “patient” (time from first symptoms to first consultation), “system” (time from first consultation to first diagnosis) and total (time from first symptoms to diagnosis) median diagnostic delay were estimated.

Results

The median “total”, “patient” and “system” diagnostic times were 37, 21 and 7 days, respectively. Of the 384 patients surveyed, 158 patients or 41.25% of patients had a long total diagnostic delay (> 45 days). The number of patients with a long system diagnostic delay was 125 patients (32.55%; p < 0.001) and those with a long patient diagnostic delay were 105 patients (27.34%; p < 0.001).

Conclusion

The total diagnosis delay of pulmonary tuberculosis was long for almost half of the patients. Awareness of the signs of tuberculosis among patients and caregivers, and consultation in a health center must be intensified to help considerably reduce these delays.

Determinants of health system diagnostic delay of pulmonary tuberculosis in Gurage and Siltie zones, South Ethiopia: a cross-sectional study

BACKGROUND

Unrecognised transmission of tuberculosis is a main contributor of high epidemic of tuberculosis in low-income countries. Studies done in Ethiopia showed that delay in tuberculosis diagnosis and treatment is one of the major challenges to tuberculosis control programmes in the country. This study assessed factors which predict health system diagnostic delay of new pulmonary tuberculosis in Gurage and Siltie zones, South Ethiopia.

METHODS

A health facility-based cross-sectional study was conducted among 204 adult patients with new pulmonary tuberculosis in Gurage and Siltie zones. Consecutive sampling technique was used to recruit participants. Data were collected by using a structured and pretested Amharic questionnaire. Data were entered into Epi-info V.7, processed and analysed by SPSS V.20. Health system diagnostic delay was dichotomised as either long or acceptable delay using median delay.

RESULTS

Median (IQR) patient and health system diagnostic delays are almost equal which are 20 (10-34.5) and 20.5 (8.2-56.2) days, respectively. Results from logistic regression show that presence of long patient delays (adjusted OR (AOR)=2.85, 95% CI: 1.44 to 5.62; p=0.003) in seeking care, presence of sputum smear examination (AOR=0.37, 95% CI: 0.19 to 0.75; p=0.005) at the first visit to a health facility and multiple heath facility visit before diagnosis of tuberculosis (AOR=4.95, 95% CI: 1.98 to 12.40; p=0.001) were factors significantly associated with long health system diagnostic delay.

CONCLUSIONS

Long patient delay and multiple health facility visits are positively associated with long health system diagnostic delay; whereas sputum smear examination at the first contact with a health facility is negatively associated with long health system tuberculosis diagnostic delay.

Long-term trends of tuberculosis incidence and mortality in four central African countries

Tuberculosis (TB) incidence and mortality rates are still high in Sub-Saharan Africa, and the knowledge about the current patterns is valuable for policymaking to decrease the TB burden. Based on the Global Burden of Disease (GBD) study 2019, we used a Joinpoint regression analysis to examine the variations in the trends of TB incidence and mortality, and the age-period-cohort statistical model to evaluate their risks associated with age, period, and cohort in males and females from Cameroon (CAM), Central African Republic (CAR), Chad, and the Democratic Republic of the Congo (DRC). In the four countries, TB incidence and mortality rates displayed decreasing trends in men and women; except for the males from DRC that recorded an almost steady pattern in the trend of TB incidence between 1990 and 2019. TB incidence and mortality rates decreased according to the overall annual percentage changes over the adjusted age category in men and women of the four countries, and CAM registered the highest decrease. Although TB incidence and mortality rates increased with age between 1990 and 2019, the male gender was mainly associated with the upward behaviors of TB incidence rates, and the female gender association was with the upward behaviors of TB mortality rates. Males and females aged between 15–54 and 15–49 years old were evaluated as the population at high risks of TB incidence and mortality respectively in CAM, CAR, Chad, and DRC. The period and cohort relative risks (RRs) both declined in men and women of the four countries although there were some upward behaviors in their trends. Relatively to the period and cohort RRs, females and males from CAM recorded the most significant decrease compared to the rest of the countries. New public health approaches and policies towards young adults and adults, and a particular focus on elderlies’ health and life conditions should be adopted in CAM, CAR, DRC, and Chad to rapidly decrease TB incidence and mortality in both genders of the four countries.

Treatment seeking delay and associated factors among tuberculosis patients attending health facility in Ethiopia from 2000 to 2020: A systematic review and meta analysis

Background

Treatment seeking delay is defined as the time interval between the onset of the major symptoms of tuberculosis (TB) and the first visit to the formal health care facility. The patient was said to be delayed if the patient visited the health-facility after 3 weeks onset of major symptoms. However, in low-income countries like Ethiopia, the delay in treatment-seeking among tuberculosis patients contributes to a widespread transmission and high prevalence of tuberculosis.

Methods

Studies were retrieved from PubMed, Cochrane Database, Cinahl, Scopus, Mednar, and Google Scholar by employing a combination of search terms with Boolean operators. Heterogeneity across studies was assessed using the Cochrane Q test. A funnel plot was used for visual assessment of publication bias. Subgroup analyses were performed to explore the possible causes of heterogeneity. Egger’s weighted regression test at a p-value < 0.05 was used to assess the presence of publication bias. Sensitivity analysis was performed to judge whether the pooled effect size was influenced by individual study. STATA software version 14 was used for all statistical analyses.

Result

A total of 12 studies with 5122 total sample size were included. The national pooled prevalence of treatment seeking delay was 44.29% (95% CI: 39.805, 48.771). The visual inspection of the funnel plot showed the asymmetrical distribution, and the Egger test showed insignificant (P = 0.348). Patients who did not seek formal health care providers on a first contact had about 7 times more likely to delay than patients who sought formal health care provider on a first contact (OR: 7.192 ((95% CI 5.587–9.257), P = 0.001, I²: 85%). The others independent predictors of delay were rural residence (OR: 3.459 ((95% CI 1.469–8.148), P ≤ 0.001), extra pulmonary TB (OR: 2.520 ((95% CI 1.761–3.605), 0.180), lower educational level (OR 11.720 ((95% CI 1.006–2.938), P <0.001), and distance more than 10km from health facility (OR: 1.631 ((95% CI (10.858–3.101), P = 0.001).

Conclusion

In this review, we identified a substantial treatment seeking delay among TB patients in Ethiopia. And, the independent predictors of delay were treatment sought before formal health care provider, residence of the patient, type of TB, educational level, and distance from a health facility. Thus, we recommend health extension workers, health professionals and other stakeholders to focus on patient education, and to continuously mobilize the whole communities on early treatment seeking with a special emphasis given to where treatment sought before formal health care provider, rural resident, extra pulmonary TB, and a patient living farther than 10km distance from health facility.

Utilization of traditional medicine in primary health care in low- and middle-income countries: a systematic review

This paper reports the findings from the first systematic review of the utilization of traditional medicine (TM) in primary health care (PHC) in low- and middle-income countries (LMICs). PHC is an important component of health care and essential for achieving universal health coverage (UHC). For countries where there is a gap in PHC, TM plays a vital role. It is widely used and has the potential to increase the coverage of PHC and UHC. Hence in situations where TM is recognized in a considerable magnitude, there are scarce evidence and minimal regulation on it and TM practitioners (TMPs). This study aims to identify the current situation in the utilization of TM in PHC or UHC in LMICs. A systematic review and thematic synthesis of qualitative and quantitative studies have been conducted. A total of 56 articles met the criteria and were included in the review. In all, 14 analytic themes have been developed including the current use of TM in PHC, higher accessibility of TM, medical pluralism, national health system, national health policy and national health insurance to include TM, including TMPs in the referral system, utilizing TMPs as community health workers, the needs of scientific research on TM and the need for training both TMPs and conventional medical staffs for better collaboration. The study concluded that it is necessary to further focus on TM in the macro level on strengthening the referral system by including TM to establish a comprehensive service delivery network under UHC and in the micro level to focus on training the TMPs and conventional medicine health workers on both areas to attain more in-depth understanding of each other, which can lead to better collaboration and quality patient care.

Factors associated with treatment initiation delay among new adult pulmonary tuberculosis patients in Tigray, Northern Ethiopia

Background

Delayed treatment initiation of Tuberculosis patients results in increased infectivity, poor treatment outcome, and increased mortality. However, there is a paucity of evidence on the delay in new adult pulmonary Tuberculosis patients to initiate treatment in Tigray, Northern Ethiopia.

Objective

To assess the factors associated with treatment initiation delay among new adult pulmonary tuberculosis patients in Tigray, Northern Ethiopia.

Methods

The study design was cross-sectional. A total of 875 new adult pulmonary tuberculosis patients were recruited from 21 health facilities from October 2018 to October 2019. Health facilities were selected by simple random sampling technique and tuberculosis cases from the health facilities were consecutively enrolled. Data were collected using structured questionnaire within the first 2 weeks of treatment initiation. Delay was categorized as patient, health system and total delays. Data were analyzed using SPSS version 21 and logistic regression was used to identify factors associated with the odds of delays to initiate treatment. A p-value of less than 0.05 was reported as statistically significant.

Results

The median patient, health system and total delays were 30, 18 and 62 days, respectively. Rural residence, being poor, visiting non-formal medication sources, being primary health care and the private clinic had higher odds of patient delay whereas being HIV positive had lower odds of patient delay. Illiteracy, first visit to primary health care and private clinic had higher odds of health system delay whereas a visit to health facility one time and have no patient delay had lower odds of health system delay.

Conclusion

The median patient delay was higher than the median health system delay before initiating treatment. Hence, improved awareness of the community and involving the informal medication sources in the tuberculosis pathways would reduce patient delay. Similarly, improved cough screening and diagnostic efficiency of the lower health facilities would shorten health system delay.

Seeking care from a traditional healer after injury in Sudan: an exploratory cross-sectional analysis

BACKGROUND

Seeking care from traditional healers for injury is a common practice in low- and middle-income countries, including Sudan. As little is known about specific patterns of the practice in the country, we aimed to investigate associated factors and the role of professional injury care availability.

METHODS

We used Sudan Household Health Survey 2010 data from a national stratified multistage cluster sample of 15 000 households. A multivariable Poisson regression (PR) model with robust variance was used to test potential associations of receiving care from a traditional healer in the first week after injury with age, gender, urban/rural residence, wealth index, educational attainment, cause of injury, time of injury occurrence and state-level injury-care bed density.

RESULTS

Of 1432 injured participants who sought some form of healthcare, 38% received care from a traditional healer. A significant negative association was found with educational attainment, age and wealth. The association between injury-care bed density and receiving care from a traditional healer was consistently evident only when the injury was caused by a road traffic accident (PR = 0.90, 95% CI 0.85 to 0.96).

CONCLUSIONS

Merely increasing the affordability or availability of injury care facilities may not impact reliance on traditional healers for all causes of injury. Therefore, injury care policies need to consider the role of traditional healers as part of the healthcare system.

Delay in diagnosis of pulmonary tuberculosis in low-and middle-income settings: systematic review and meta-analysis

Background

Assessment 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.

Methods

It 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.

Results

Forty 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.

Conclusion

Delay 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.

Factors associated with the length of delay with tuberculosis diagnosis and treatment among adult tuberculosis patients attending at public health facilities in Gondar town, Northwest, Ethiopia

Background

Early diagnosis and prompt treatment is essential for an effective tuberculosis (TB) control program. However, significant proportion of cases remains undiagnosed and untreated. Delay in diagnosis and treatment increases transmission. Hence, the study assessed the length of delay and associated factors with tuberculosis diagnosis and treatment among adults attending public health facilities in Gondar town, Northwest Ethiopia.

Method

An institution based cross-sectional study was conducted from February to May, 2016. A total of 296 adults who came to health facilities for treatment for pulmonary TB from February to May, 2016, were included in the study. Data were collected using a structured questionnaire through interviewing and record review, cleaned, coded, and entered into Epi-info version 3.5.3, and transferred into SPSS version 20.0 for further statistical analysis. A p-value of less than 0.05 at multiple linear regression analysis was considered statistically significant.

Result

The mean duration of the total delay (in days) for tuberculosis diagnosis and initiation of treatment was 41.6 days (SD = 16.6). In this study, the mean duration of patient delay and the median health system delay were 33.9 days (SD = 14) and 5 days (IQR = 4–7), respectively. Total delay for TB diagnosis and treatment was shorter among HIV positive people (β:-12.62, 95% CI: −20.72,-4.53). Longer patient delay was noted among rural dwellers (β: 8.0, 95% CI: 5.26, 10.75); increased household income (β:-0.006, 95% CI: −0.008,-0.004) was associated with a shorter delay. Health system delay was positively associated with seeking care from more than one health care providers (β: 0.28, 95% CI: 0.23, 0.34) and seeking initial care from primary level health care facilities (β: 0.10, 95% CI: 0.07, 0.13).

Conclusion

In this study, the majority of patients faced delayed in seeking health care and continued as sources of infection. Longer days of delay for TB diagnosis and treatment were noted among rural residents, who seek health care from informal care providers, and receive initial care from primary level health care facilities. In contrast, the length of delay for TB diagnosis and treatment was shorter among HIV positive people and individuals with increased household income. Therefore, public awareness on the symptoms of tuberculosis and seeking health care early is essential. Moreover, early diagnosis and treatment, especially among the rural dwellers and the poor should be focused.

Barriers to initiating tuberculosis treatment in sub-Saharan Africa: a systematic review focused on children and youth

BACKGROUND

Tuberculosis (TB) is the deadliest infectious disease globally, with 10.4 million people infected and more than 1.8 million deaths in 2015. TB is a preventable, treatable, and curable disease, yet there are numerous barriers to initiating treatment. These barriers to treatment are exacerbated in low-resource settings and may be compounded by factors related to childhood.

OBJECTIVE

Timely initiation of tuberculosis (TB) treatment is critical to reducing disease transmission and improving patient outcomes. The aim of this paper is to describe patient- and system-level barriers to TB treatment initiation specifically for children and youth in sub-Saharan Africa through systematic review of the literature.

DESIGN

This review was conducted in October 2015 in accordance with preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. Six databases were searched to identify studies where primary or secondary objectives were related to barriers to TB treatment initiation and which included children or youth 0-24 years of age.

RESULTS

A total of 1490 manuscripts met screening criteria; 152 met criteria for full-text review and 47 for analysis. Patient-level barriers included limited knowledge, attitudes and beliefs regarding TB, and economic burdens. System-level barriers included centralization of services, health system delays, and geographical access to healthcare. Of the 47 studies included, 7 evaluated cost, 19 health-seeking behaviors, and 29 health system infrastructure. Only 4 studies primarily assessed pediatric cohorts yet all 47 studies were inclusive of children.

CONCLUSIONS

Recognizing and removing barriers to treatment initiation for pediatric TB in sub-Saharan Africa are critical. Both patient- and system-level barriers must be better researched in order to improve patient outcomes.

[The "Health system delay" in tuberculosis patients in Saint-Louis Senegal]

Sixty patients with positive acid fast bacilli sputum smears between were enrolled consecutively between March and August 2012 in the Saint-Louis (Senegal) health district to determine the Health System Delay in response to tuberculosis. The length of time between the first consultation of a TB patient and the start of treatment was, on average, 8.1 days and is among the shortest in the literature. This promptness reduces the risk of infection related to delayed care. This is one of the focuses of the National Programme of Fight against nosocomial infections in Senegal (PRONALIN), as well as the implementation of environmental procedures and the use of masks and respiratory protection equipment.

Time to first consultation, diagnosis and treatment of TB among patients attending a referral hospital in Northwest, Ethiopia

Background

Early detection and treatment of TB is essential for the success of TB control program performance. The aim of this study was to determine the length and analyze predictors of patients’, health systems’ and total delays among patients attending a referral hospital in Bahir Dar, Ethiopia.

Methods

A cross-sectional study was conducted among newly diagnosed TB cases ≥ 15 years of age. Delay was analyzed at three levels: the periods between 1) onset of TB symptoms and first visit to medical provider, i.e. patients’ delay, 2) the first visit to a medical provider and the initiation of treatment i.e. health systems’ delay and 3) onset of TB symptoms and initiation of treatment i.e. total delay. Uni- and multi-variate logistic regression analyses were performed to investigate predictors of patients’, health systems’ and total delays.

Results

The median time of patients’ delay was 21 days [(interquartile range (IQR) (7 days, 60 days)]. The median health systems’ delay was 27 days (IQR 8 days, 60 days) and the median total delay was 60 days (IQR 30 days, 121 days). Patients residing in rural areas had a three-fold increase in patients’ delay compared to those from urban areas [Adjusted Odds Ratio (AOR) 3.4; 95% (CI 1.3, 8.9)]. Extra-pulmonary TB (EPTB) cases were more likely to experience delay in seeking treatment compared to pulmonary (PTB) cases [(AOR 2.6; 95% (CI 1.3, 5.4)]. Study subjects who first visited health centres [(AOR) 5.1; 95% (CI 2.1, 12.5)], private facilities [(AOR) 3.5; 95% (CI 1.3, 9.7] and health posts [(AOR) 109; 95% (CI 12, 958], were more likely to experience an increase in health systems’ delay compared to those who visited hospitals.

Conclusions

The majority of TB patients reported to medical providers within an acceptable time after the onset of symptoms. Rural residence was associated with patients’ and total delays. Providing the population with information about TB symptoms and the importance of early health seeking may be an efficient way to decrease TB transmission, morbidity and mortality. Establishing efficient TB diagnostic and treatment facilities at the periphery level is imperative to reduce diagnostic delay and expedite TB treatment.
