Objective To understand the delays in medical consultation among tuberculosis (TB) patients in Lu'an City from 2021 to 2023 and analyze the influencing factors,providing a basis for TB prevention and control efforts. Methods Data on TB patients from the TB management information system were exported from the years 2021-2023 (4 658 cases),including age,gender,occupation,ethnicity,etc.After excluding cases with obvious logical errors (48 cases),an analysis of the delayed medical consultations among 4 610 TB patients was conducted,primarily using Chi-square tests and multivariate logistic regression analysis. Results The median consultation time for the 4 610 TB patients was 26 days (interquartile range:12-47),with a consultation delay rate of 70.37% (3 244/4 610).A year to year comparisons showed that 2021 had the highest delay rate (75.22%),2022 with the lowest rate (62.81%) (χ²=57.931,P<0.001).Comparisons between districts showed that the highest delay rate was in Yu'an District (84.12%),followed by Jinzhai County (74.92%) (χ²= 216.588,P<0.001).The results of the multivariate logistic regression indicated that age between 65 and 94 years (OR=0.671,95%CI:0.455~0.990),presence of comorbidities (OR=0.827,95%CI:0.702~0.975),and retreatment (OR= 0.477,95%CI:0.389~0.584) were protective factors against delayed medical consultation,while being unemployed or engaged in household duties (OR= 1.632,95%CI:1.230~2.165) was a risk factor for delayed medical consultation. Conclusion The delay rate for medical consultation among TB patients in Lu'an City is relatively high.Targeted health education and proactive screening should be conducted for different populations based on the identified risk factors to reduce the transmission of active TB among the population.
