[Risk factors in the delay of treatment of childhood tuberculosis in a Peruvian Hospital].

Childhood tuberculosis (c-TB) continues to be one of the causes of morbidity and mortality in children, but there is still little information on the delay in the initiation of specific treatment.

Objective: To determine the risk factors associated with delayed initiation of tuberculosis (TB) treatment in children under 15 years of age.

Patients and method: Case-control study. Patients <15 years of age with a diagnosis of childhood pulmonary tuberculosis (c-PTB) with delayed treatment initiation >24 hours were included. Clinical and epidemiological variables were evaluated: age, gender, guardian's education, poverty level, origin, family history of TB, altered imaging findings, symptomatic, PPD >10mm, histology, bacteriology, resistance to treatment, and healthcare network. Bi and multivariate logistic regression analysis was performed, through which odds ratios were calculated.

Results: We evaluated 116 patients with c-PTB with a delayed initiation of specific treatment of more than 24 hours, and 264 with start of treatment in the first 24 hours. The delay in anti-tuberculosis treatment had a median of 3 days with an interquartile range of 2 to 7 days. The patient with the least educated guardian had a delay in treatment initiation with an odds ratio of 7.47 (95%CI: 4.13 - 13.52). Belonging to the healthcare network A of Callao decreased the probability of having tuberculosis by 0.224 times (95%CI:0.11 - 0.46).

Conclusion: Incomplete education level of the guardian is a risk factor associated with delayed initiation of c-PTB treatment in children under 15 years of age while belonging to the Callao healthcare network A is a factor that decreases the risk in the group under study.
