Objective: The study sought to assess the approach to and awareness of tuberculosis diagnosis and treatment by health workers in primary health care delivery. Material and Methodology: This cross-sectional survey was conducted in the period April – June 2019 with the participation of family medicine physicians and family health workers in Sivas province. Approvals were taken from the ethics committee and relevant government authorities. Participants were applied sociodemographic data form and Tuberculosis Knowledge Level Form. Mann Whitney U test, Kruskal Wallis test (post-hoc Mann Whitney U test) and chi-square test were used in data analysis. Findings: An overwhelming majority of health workers covered by the survey have never worked in a tuberculosis control dispensary (96.5%), not taken any training about tuberculosis within the last 12 months (88.3%) and performed no active duty in patient follow up and treatment in tuberculosis in their professional life (53.6%). Average scores in Tuberculosis Knowledge Level Form are higher among those over age 40 than under, among men than women, among physicians than midwives and nurses, among those who have earlier worked in Tuberculosis Control Dispensaries than those who have not, among those who have received training in tuberculosis within the last year than others who have not, and among those who have met tuberculosis patients and took active duty in their care than others who have not. The level of tuberculosis information is at satisfactory level among men (57.8%) and physicians (57.9%). Conclusion: Given the fact that there is increase in treatment-resistant cases, the shortness of information on the part of both family health workers and family physicians on tuberculosis prevalence and treatment is well worth noting. It may therefore be suggested to update tuberculosis-related information and introduce more frequent trainings to build awareness about new developments in this field.
