Background
Delays in diagnosis and treatment of tuberculosis (TB) increases severity of illness and continued transmission of TB in the community. Understanding the magnitude and factors associated with total delay is imperative to expedite case detection and treatment of TB. The aim
of this study was to determine the length and analyze factors associated with total delay.

Methods
Analytic cross-sectional study was conducted in Jimma Zone, Southwest Ethiopia. All newly
diagnosed TB patients > 15 years of age were included from randomly selected eight districts and one town in the study area. A structured questionnaire was applied to collect
socio-demographic and clinical data. The median total delay was used to dichotomize the
sample into delayed and non-delayed patient categories. Logistic regression analysis was
used to analyse the association between independent and outcome variables. A p-value <
0.05 were considered statistically significant.
Results
A total of 1,161 patients were included in this study. The median total delay was 35 days.
Patients who had swelling or wound in the neck region were more likely to be delayed than
their counterpart [adjusted odds ratio (AOR) = 3.02, 95% confidence interval (CI): 1.62,
5.62]. Women were more likely to experience longer total delay (AOR = 1.46, 95% CI:1.00,
2.14) compared to men. Patients who had poor knowledge of TB were more likely to be
delayed compared to those who had good knowledge (AOR = 3.92, 95% CI: 2.65, 5.80).

Total delay and associated factors among tuberculosis patients
Conclusion
The present study showed long total delay in diagnosis and treatment of TB. Targeted interventions that enhance TB knowledge and practice, expedite early suspect identification,
referral and management of all forms of TB is imperative to reduce total delay in diagnosis
and treatment of TB.

1. Introduction
Tuberculosis (TB) is a major cause of illness in low-resource countries. It is among the top 10
causes of death, and has been the leading cause of death from a single infectious agent in recent
years [1, 2]. There were an estimated 10.0 million TB cases, and 1.5 million deaths due to TB
in 2020 [3]. The 30 high TB burden countries are responsible for the majority (86%) of the estimated incident TB cases [2].
Ethiopia is among the high TB burden countries [3]. TB is a major public health problem
and one of the leading infectious diseases in Ethiopia. There were an estimated 140 new incident TB cases per 100,000 population in 2020 and TB mortality rate of 19 per 100,000 populations in 2019 in Ethiopia [4]. Ethiopia accounts for 90,000 (3%) of annually missed TB cases
worldwide [2, 5]. A recent national case detection rate of all forms of TB was 76 percent, which
is below the target of World Health Organization [3, 6]. One of the contributing factors for
low case detection is the delay in diagnosis and treatment of TB. Delay in diagnosis and treatment is commonly divided into three components (patients’ delay, health system’s delay and
total delay). While patient delay refers to the delay period from onset of the major TB symptoms to first visit to a medical provider, health system delay encompasses the delay period
from first visit to a medical provider to first start of anti-TB treatment. Total delay is defined as
the delay period from start of major TB symptoms to first start of anti-TB treatment. Delay in
TB diagnosis and treatment remains a major problem of TB control program generally in low
and middle income countries [7] particularly in Ethiopia [8, 9]. Patients’ health care seeking
delay differs among different regions of Ethiopia [10, 11].
Prompt diagnosis and treatment is crucial for efficient TB control program performance
and achieving the End TB targets. The target set for the End TB Strategy for the year 2035
include: 1) reduction of TB mortality by 95%, 2) decreasing TB incidence by 90% (i.e compared to the baseline of 2015), and 3) to certify that no family is suffered with TB related catastrophic costs [12]. The End TB Strategy targets can only be realized if diagnosis, treatment,
and preventive services for TB are delivered based on the context of universal health coverage,
which implies that all people with TB should be early detected and properly treated [2, 5].
Delayed diagnosis and treatment of TB cases has major role in the transmission of the disease
in the community in most high TB burden countries. Early diagnosis and proper treatment of
TB will re (...truncated)
