Abstract

Delays in diagnosis and isolation raise the possibility of nosocomial tuberculosis transmission (TB). We examined the risk variables of lengthy delays in isolation of smear-positive TB patients in pulmonology/infectious diseases and other wards at a tertiary teaching hospital to assess the danger of delayed care of the disease. After being admitted to the hospital, we enrolled older smear-positive TB patients who had undergone delayed respiratory isolation. Retrospective review of medical records was performed.
Key Words: Screening, tuberculosis, pleural disease, interventional pulmonology. Between pulmonology/infectious diseases wards (PIWs) and other wards, the times between admission, the sequence of sputum acid-fast staining, the start of anti-tuberculous treatment, and isolation were compared. Patients with a week-long delayed isolation delay underwent individual group analyses of risk variables. In hospitalised TB patients with positive smear tests, isolation was postponed. In PIWs, day was the median for suspicion, treatment, and isolation delays.

Introduction

Controlling tuberculosis (TB) requires minimizing its transmission within hospitals and other healthcare settings. There have been many reports of nosocomial TB outbreaks. Through testing for severe acute respiratory syndrome, an outbreak of nosocomial transmission of Mycobacterium tuberculosis was identified. In healthcare facilities around the United States, disease control and prevention practices are commonly used. The reduction in TB outbreaks and transmission of M. tuberculosis to patients and healthcare workers in healthcare institutions has made the effects immediately clear. In order to develop efficient anti-tuberculous chemotherapy regimens, infection control strategies should include measuring the time intervals between admission and suspicion, diagnostic tests, isolation, and treatment commencement. Because there are more contagious patients treated in pulmonology/infectious diseases wards, there is assumed to be a higher risk of exposure to TB. Additionally, infectious disease experts and pulmonologists are better aware of the radiographic signs of TB and familiar with its symptoms. Because of this, TB patients in PIWs are more likely to receive an early diagnosis. As a result, we anticipated that treatment, isolation, and delayed diagnosis might all be shorter in these settings. To assess the danger of unprotected exposure to TB, time intervals were computed and risk variables for delayed isolation of adult TB patients with positive sputum acid-fast staining (AFS) were examined. The CGMH Committee for Infection Control provided the patient list. There was a look back at medical records. There were TB patients who were reported. The majority of the reported TB patients were handled in outpatient clinics rather than hospitals due to the dearth of suitable negative-pressure isolation rooms. Hospitalization was restricted to those having positive sputum acid-fast staining and cultures. Patients with positive acid-fast staining. Tuberculosis cultures in respiratory tract specimens who weren't immediately moved into negative-pressure isolation rooms after admission were considered to have experienced delayed isolation. Patients with respiratory isolation delays that lasted longer than a week after admission were considered to have experienced prolonged isolation delays. In order to categorize all patients, we divided them into groups PIW (pulmonology and infectious illnesses wards) and non-PIW (other hospital wards, such as non-pulmonary/ infectious diseases medical wards or non-medical wards). The CGMH Ethics Committee gave their approval to this study. Gen- der, age, comorbidity, first symptoms, and ward of admission were among the demographic information gathered. At the time of admission, chest radiographs were examined for the presence of cavitation, military lesions, or prominent upper lobe abnormalities. Atypical chest radiographs for TB were those without any of the aforementioned features. Diabetes mellitus, end-stage renal disease, chronic renal insufficiency, hematologic diseases, autoimmune diseases, neurologic disorders, usage of immunosuppressive medications, and cancer were all examples of comorbidity. The earliest signs, such as a cough, sputum production, fever, breathlessness, hemoptysis, body weight loss, or exhaustion, were noted. Dates of available chest radiographs following admission, sputum AFS orders, anti-tuberculous treatment starts, and negative pressure room isolation dates were also gathered. Calculated were the times between admission and respiratory isolation, admission and ordering of AFS, admission and starting ant tuberculous treatment, and between the ordering of sputum AFS and isolation. Patients who were hospitalized in the emergency room (ED) had information about whether sputum AFS had been ordered there. If a chest radiograph or sputum AFS was ordered prior to admission, the admission-AFS and admission-chest radiograph intervals were both specified as days.

When comparing the traits of patients with delayed isolation in the PIW and non-PIW groups, continuous variables were compared using an independent t-test, and categorical variables were compared using a 2 or Fisher's exact test. Days between various therapies were compared using the Mann-Whitney U test on non-parametric data. The Kaplan-Meier approach was used to calculate the overall percentage of patients who were isolated after admission. The stepwise method of multiple logistic regression analysis was employed to investigate the factors of extended isolation delays in certain groups. Whether the delayed isolation lasted longer than a week was the dependent variable. Age, gender, comorbidities, first symptoms, chest X-ray results, and the status of the AFS order in the ED were independent variables.

Each individual was subjected to the analysis separately, as well as the PIW and non-PIW groups. Diabetes mellitus, chronic lung disease, chronic renal insufficiency, cardiovascular disorders, neurologic diseases, and cancer were the most frequently occurring comorbidities. With the exception of the number of patients who arrived with cancer and neurological disorders in the non-PIW group, most comorbidities were distributed similarly across the two groups. There were more patients in the PIW group who had a fever and respiratory symptoms such as cough, hemoptysis, and sputum production, but there was no difference between the two groups in terms of dyspnea, weight loss, or fatigue. Predominant upper lobe lesions were the chest radiograph finding that was seen the most frequently. However, there was no statistically significant difference between the PIW and non-PIW patients in the percentage of patients having lesions that were mostly upper lobe lesions, cavitation’s, or military lesions on chest radiographs. Atypical chest radiographs without any conspicuous upper lobe lesions, cavitation, or military lesions were found in patients with delayed isolation. In the non-PIW group, there were more patients who presented with atypical chest radiographs for TB, albeit this difference was not statistically significa--nt. Patients that experienced delayed isolation were admitted from the ED. Sputum AFS had been requested for ED patients since TB was suspected. In the PIW group, a larger percentage of patients had sputum AFS ordered in the ED. The median time spans between being admitted and having sputum AFS ordered, anti-tuberculous treatment started, and respiratory isolation started were day by day. The time between admission and each intervention, such as the time between admission and the beginning of anti-tuberculous treatment and the time between admission and isolation, was all shorter in the PIW group than in the non-PIW group. The time between ordering sputum AFS and getting a chest x-ray was likewise shorter in the PIW group. The median time between suspicion and isolation, as well as between the ordering of sputum AFS and respiratory isolation, was days. According to the Kaplan-Meier estimate, the median delay in isolation (from admission to isolation) was days for the PIW group and days for the non-PIW group. In comparison to the non-PIW group, the number of patients with isolation delays longer than a week was considerably lower in the PIW group. Entry into a PIW or non-PIW was not a significant factor in the multivariate logistic regression model. Even though there was a significant interaction with other variables, the estimate was not reliable because the confidence ranges were quite large. Thus, only the results for PIWs and non-PIWs, respectively, were provided. The only significant independent predictor linked with a higher likelihood of prolonged isolation delay in patients admitted to a PIW was age years. Patients without dyspnea, those with unusual chest radiographs, and people who weren't admitted from the ED had a higher risk of prolonged isolation delay in nonPIWs. Because the tuberculin skin test was not frequently administered to hospital staff members during the study period, it was challenging to determine the risk of nosocomial TB transmission at the hospital. Patients who are not immediately placed in respiratory isolation risk contracting tuberculosis (TB). The absence of particular manifestations may put off suspicion, diagnosis, and ultimately respiratory isolation. HCWs are more likely to develop TB if they were exposed to infectious TB unprotected before developing a TB suspect and receiving the appropriate respiratory isolation.

In earlier investigations, the length of management delays has varied. Hospitalized TB cases were not discovered right away, weren't diagnosed for four weeks after admission, and weren't treated the entire time they were there. Reported a days-long median treatment delay, with management delays of more than a week for up to onethird of these patients. In hospitalized patients getting delayed therapy, the median time from admission to isolation was days, and this included both smear-positive and smear-negative TB patients. The current investigation demonstrated that AFS-positive TB patients who were hospitalized were initially not handled appropriately. In this investigation, the median treatment delay was one day, while the median length of delayed respiratory isolation was days. As the danger of TB transmission per hospitalized TB patient declines, the number of TB admission rises. The majority of TB patients are managed by pulmonologists and infectious disease experts, who are also the most familiar with their symptoms and radiologic findings. The current investigation showed that TB patients in PIWs saw considerably shorter wait times for respiratory isolation and suspected therapy. Patients had more than a weeklong delay in respiratory isolation. In comparison to the PIW group, the proportion of patients with extended delays was noticeably higher in the non-PIW group. However, after adjusting for other variables, the ward of admission was not a significant factor in the multiple regression model that included all study participants for prolonged isolation delay. There was no discernible difference between these two groups in the percentage of patients with abnormal chest radiographs. In PIWs, there were more patients with fever and respiratory symptoms including cough, sputum, or hemoptysis. AFS was requested at the ED in a larger percentage of TB patients admitted to PIWs who had TB suspicions. Fewer patients had TB suspected in the ED and the majority of diagnoses for patients in non-PIWs were unrelated to pulmonary illness. The ED was not the ward of admission; rather, the risk variables for delayed diagnosis and isolation were things like symptoms, radiological presentations, or sputum AFS. Multiple logistic regression analysis revealed that patients in the non-PIW group who did not have dyspnea, had abnormal chest radiographs, and were not admitted from the ED had a higher probability of delayed isolation for a week. On the other hand, PIW patients' longer isolation delay was not correlated with respiratory symptoms, systemic symptoms, patterns of chest radiographs, or AFS ordering at the ED. Patients with infectious TB who are hospitalized frequently arrive from the ED. In order to provide firstline defense against nosocomial transmission of infectious diseases including TB, SARS, and other communicable respiratory disorders, doctors at the ED serve as the "gatekeeper." Our patients who required delayed respiratory isolation were transferred from the ED to the hospital. For the earlier diagnosis of infectious TB in hospitalized patients, ring sputum AFS for all patients with pulmonary infiltrates at the ED, but not just for those with conventional chest radiographs, may be helpful. Due to a shortage of negative-pressure isolation rooms, only patients who have respiratory specimens that test positive for AFS are hospitalized. The isolation of these contagious TB patients may take longer as a result. In the current study, the median amount of time between suspicion and isolation was three days. The period of isolation might be decreased by a median of days if all TB suspicions were correctly isolated before AFS results became available. In a US hospital, an enhanced respiratory isolation policy was put into place to isolate everyone who was TB suspect. This effectively isolated TB patients upon admission, but it also caused isolation rooms to be used eight times more frequently than necessary.
