The epidemiological control and eradication of tuberculosis may be negatively impacted by excessive delays in diagnosis. It may be possible to determine where and how to enhance tuberculosis detection in accordance with regional demands by accurately determining and analyzing delay durations. The primary source of information on diagnosis delays is the Portuguese Tuberculosis Surveillance System SVIG-TB. To our knowledge, the data's most recent examination hasn't taken place. The main objective of this study was to thoroughly evaluate data from the SVIG-TB registry about the delay in tuberculosis diagnosis in the Portuguese municipality of Matosinhos. Individual SVIG-TB records for every patient in the Matosinhos municipality who has been diagnosed with tuberculosis have been collected. Based on information gathered from this source and contrasted with information discovered from a study of patient records, the patient-related, healthcare-related, and overall delays in tuberculosis diagnosis were identified. Data gaps, entry mistakes, and variations in diagnosis latency between these two sources were examined and contrasted. Then, local SVIG-TB and patient record review data were compared to diagnosis delay data from a recent Portuguese national SVIG-TB publication that covered years. When compared to Patient Record Review, this study found a considerably higher percentage of cases with incomplete information on delay in SVIG-TB records. The overall, median, and patient-related delays in diagnosing tuberculosis.
