Abstract

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.

Introduction

Portugal still has one of the highest frequencies of this illness Pdespite having continuous and efficient national public health strategies aimed at eliminating Tuberculosis (TB). The specific responsibility for TB diagnosis, treatment, and prevention in Portugal falls to outpatient TB clinics. Nonetheless, TB can be identified in any healthcare facility, including public and private ones, primary, secondary, and even tertiary care facilities, with a subsequent referral to the latter for follow-up. For more than 20 years, the national surveillance program for tuberculosis in Portugal, known as "SVIGTB," has enabled the systematic gathering of standardized epidemiological data. The major objective of this surveillance system is to gather updated information on susceptibility tests, microbiological evolution, and treatment protocols. In Portugal, it has proven crucial for the epidemiological understanding and management of this disease. The dates of patient symptom discovery, their initial medical visit, and the start of their treatment may all be found in the data gathered from SVIG-TB and used to calculate the overall patient and medical system delays in TB diagnosis. Both the patient reporting (mostly recall bias) and the healthcare professional registering this data are liable for bias and inaccuracy in the records of this information. One of the identified barriers to effective epidemiological control of TB (especially of its transmissible presentations) is excessive diagnosis delay because it may have a negative effect on the disease's severity, mortality rate, and duration of truth ansmission. This, in turn, may increase contact exposure and infection, undermining the disease's control and elimination in the short and long terms. Several studies have examined the delay in TB diagnosis in various national contexts. Analyzed Portugal's TB diagnosis backlog using SVIG-TB data. Although roughly of the examples in this research lacked missing delay data, general conclusions on the topic were still possible. The significant portion of instances that were eliminated from this research due to missing data and the unknown correctness of the collected (time) data may restrict how broadly its findings may be applied. Finds discrepancies in several important factors, including the date of diagnosis, between two TB data sources and medical records in China's National TB Surveillance System. However, there was no mention of diagnosis delay data in this article. The World Health Organization advises routine evaluation and audit of national TB registries to guarantee the accuracy of their data, especially before relying on their findings to guide policy and healthcare decisions. To the best of our knowledge, neither in Portugal nor worldwide, there have been any recent studies examining the quantitative and qualitative aspects of data in TB registries explicitly regarding TB diagnosis delay. The primary goal of this study was to thoroughly evaluate data from the SVIG-TB registry about the delay in TB diagnosis in Matosinhos, a local municipality with one of the highest TB occurrences. Two forms are part of SVIG-TB, and they should ideally be filled out by the medical professional who is in charge of diagnosing TB, starting therapy, and monitoring the patient's progress during treatment. However, this paperwork is typically completed at the outpatient TB clinic. They are regarded as a trustworthy and accurate source of information both nationally and in this particular municipality. Each patient's SVIG-TB forms were collected, and all included information was registered. These dates are considered "missing data" since their absence prevented full or partial inference of associated delays. "Date of patient symptom discovery" did not apply when patients were asymptomatic upon initial observation in the hospital context but displayed radiological abnormalities, afterward recognized as being of Tuberculosis etiology. Therefore, in these situations, the patient's delay was disregarded, and the total diagnosis delay was equated to a healthcare-related delay. Following a careful review of the patient record, all information that was taken from the SVIG-TB forms was then completed or rectified. When the SVIG-TB forms were initially filled out by healthcare personnel, all of the acquired data was accessible in the patient’s records and complete. In order to compare this amended data set with the recorded SVIG-TB data. Using the Related Samples McNamara Change Test, the percentage of missing data in the SVIG-TB and Patient Record Review data was compared. Using Fisher's exact test for categorical variables and T-test for continuous variables, patients' characteristics linked to more missing values in SVIG-TB data were then retrieved. of hospital stay by MUST categorization. Using the Kruskal-Wallis test, continuous variables were compared. The median and Interquartile Range (IQR) delay values of the SVIG-TB and Patient Record Review delay data were determined. To compare delay data from both data sources, a non-parametric, tailed Wilcoxon signed-rank test for median comparisons was first applied to the entire sample. Additionally, Complete Case Analysis improved accuracy by avoiding cases with "negative" delays and choosing cases where neither sample had any missing data. In order to compare the patient-related, healthcarerelated, and overall median delays found in the SVIG-TB and patient record review data, nonparametric tests for related samples were used. The results from these SVIG-TB national records were from slightly different, but partially overlapping time periods, therefore a brief comparison between them and our current data was deemed pertinent. To compare the Matosinhos delay results from each local data source with the national SVIG-TB delay data, a non-parametrictailed Wilcoxon signed-rank test for median comparisons was used. Utilizing a version of the Statistical Package for the Social Sciences (SPSS), statistical analysis was carried out. P-values were considered significant if they fell below. The local healthcare [Undead Local de Saudi Matosinhos (ULSM)] ethics committee gave its approval before any data could be gathered. Records from the neighborhood Outpatient TB Clinic and SVIG-TB forms contained information on a total of patients. Six patients were excluded when a second TB diagnosis was rejected, and cases were excluded because they didn't live in the Matosinhos municipality. There was a definite male patient predominance. And the lungs were the most frequently affected organs, with all extrapulmonary TB cases affecting the lungs. No information on the date of diagnosis or the start of treatment was missing from either data source for the patients that were chosen. On the other hand, information from the SVIG-TB forms was missing for the dates of the initial patient symptom discovery, the first patient healthcare visit, and both. For these individuals, the delay computation was hampered by these missing dates. Occasionally, "negative" delay values were inferred, indicating the possibility of more errors in the completion of SVIG-TB forms and disqualifying them from further investigation. In terms of patient delay, healthcarerelated delay, overall delay, and diagnosis delay in SVIG-TB forms, cases lacked at least one source of data. On Patient Record Review, the number of cases in each of these three categories with missing delay data was dramatically reduced. Further investigation revealed that asymptomatic individuals had abnormal radiological exam results at the time of their initial observation in the medical environment, which were later determined to be caused by TB. Several of these incidents took place in the context of contact-screening programmers. A thorough analysis of the patient population in SVIG-TB records with and without missing delay data revealed broad similarities between them, with the exception of a few variables.

Missing information about patient-related delays was noticeably more prevalent in younger patients, patients from low-income backgrounds, and in SVIG-TB forms filled out by general practitioners (as opposed to respiratory physicians). Missing information regarding Total diagnosis delay was substantially more common in SVIG-TB forms completed by General Practitioners, detainees, and younger patients. Between patient populations with and without healthcare-related delay missing data, there were no appreciable changes. When compared to Patient Record Review data, median delays based on SVIG-TB registers showed significantly lower median delays, according to a preliminary analysis that included all accessible data from both data sources. Given the significant differences found in the population with and without missing values, as previously described as a potential source of an unforeseen selection bias, this discrepancy in results may be partially explained by the absence of data from a large sample of cases in SVIG-TB records when compared to Patient Record Review. A Complete Case Analysis method was used to account for this "asymmetry" and further enhance the accuracy of result comparison. After excluding "negative" delays, only instances where data from both sources was available were compared, including instances of patient delay, healthcare delay, and cases of Total delay. The detection of substantial disparities between Healthcare and Total median delays seen in SVIG-TB and Patient Record Review data was made possible by Complete Case Analysis. In both instances, SVIGTB data severely underestimated delays. Between patient-related delays as established from these two sources, there was no discernible difference. Data on diagnosis delays from national SVIG-TB reports were recently collected and analyzed. In this study, roughly of instances had missing patient and/or healthcare delay data, or both were missing, and these cases were also more likely to be drug addicts, inmates, or homeless. The number of cases where the complete diagnosis delay data was lacking was not disclosed. In this cohort, the medians for patient delay, healthcare delay, and total treatment delay. The major purpose of SVIG-TB forms is to gather input on the development and follow-up of TB cases. They may also be used as a source of further information, such as the delay in TB diagnosis. The WHO advises regular examination and audit of national registers to spot and reduce some of its flaws, such as missing data, record mistakes, and reporting bias.

Thorough record examination through patient record review is a time-consuming, yet easily accessible, way to examine and reduce the latter. These particulars may make it more difficult to generalize the findings to the national level and may have an impact on the results that were achieved. However, because this Municipality and its neighborhood healthcare facilities are covered by the NHS and subject to the same rules and guidelines, including those governing TB diagnosis and treatment, these findings may be applicable. Furthermore, in various geographic, socioeconomic, and cultural contexts around the world, variation is expected within healthcare institutions and teams in charge of data registry. Despite these flaws, the accuracy and interpretation of SVIG-TB data as well as policy decisions based on the former will undoubtedly be significantly impacted by missing data in more than half of reported cases, exacerbated by the likelihood of reporting bias.
