A tuberculin skin test survey among healthcare workers in two public tertiary care hospitals in Bangladesh.

ABSTRACT: In Bangladesh, there is currently no data on the burden of latent TB infection (LTBI) amongst hospital healthcare workers (HCWs). This study aimed to determine the prevalence of LTBI and compare the prevalence among HCWs in two public tertiary care hospitals. Between September 2018 and August 2019, we conducted a cross-sectional study in two public tertiary care general hospitals. Using a survey and tuberculin skin test (TST), we assessed risk factors for LTBI, adjusting for known and plausible confounders. In addition, a facility assessment was undertaken to understand the implementation of relevant IPC measures. The prevalence of LTBI among HCWs was 42%. HCWs spent a median of 6 hours (SD = 1.76, IQR 2.00) per day and attended an average of 1.87 pulmonary TB patients per week. HCWs did not receive any TB IPC training, the wards lacked a symptom checklist to screen patients for TB, and no masks were available for coughing patients. Seventy-seven percent reportedly did not use any facial protection (masks or respirators) while caring for patients. In the multivariable model adjusting for hospital level clustering effect, TST positivity was significantly higher among HCWs aged 35-45 years (aOR1.36, 95% CI: 1.06-1.73) and with >3 years of service (aOR 1.67, 95% CI: 1.62-1.72). HCWs working in the medicine ward had 3.65 (95% CI: 2.20-6.05) times, and HCWs in the gynecology and obstetrics ward had 2.46 (95% CI: 1.42-4.27) times higher odds of TST positivity compared to HCWs working in administrative areas. This study identified high prevalence of LTBI among HCWs. This may be due to the level of exposure to pulmonary TB patients, and/or limited use of personal protective equipment along with poor implementation of TB IPC in the hospitals. Considering the high prevalence of LTBI, we recommend the national TB program consider providing preventative therapy to the HCWs as the high-risk group, and implement TB IPC in the hospitals.

Project description:BACKGROUND:Pharmaceutical care has been playing an increasingly critical role in Chinese hospitals. However, evidence about the most recent development of pharmaceutical care in China is limited. This study analyzed the current situation of pharmaceutical care and the capacities of pharmacists in Chinese public tertiary hospitals. METHODS:All on-duty pharmacists of 143 public tertiary hospitals responded to the Likert-5 pre-set online questionnaire about their pharmaceutical care capacities in eight aspects, and their respective hospitals valued pharmaceutical care in clinical practice from March 18 to 31, 2019. This study measured the appraisals of the responding pharmacists as positive ("strongly agree" and "agree") or negative ("neither agree nor disagree," "strongly disagree," and "disagree") results. The study performed a descriptive analysis of the responding pharmacists and unconditional multivariate binary logistic regression analysis to predict the influencing factors of the pharmacists' appraisals of pharmaceutical care. The dependent variable was transformed into binary categories and assigned 1 = positive response and 0 = negative response. The independent variables included the identifications of sample hospitals and the characteristics of the responding pharmacists. RESULTS:The survey retrieved 10 815 valid responded questionnaires. 74.5%, 67.5%, and 65.0% of the responding pharmacists made a positive self-appraisal of their abilities of communication with patients and doctors, reviewing prescriptions, and communication with particular patients, respectively. 65.5% had a positive appraisal of their respective hospitals to conduct active monitoring of the clinical use of new medicines, and 68.9% admitted that their respective hospitals valued the clinical pharmaceutical care. The doctor's degree and senior academic rank of the responding pharmacists, as well as maternal and child hospitals, were predictors of higher appraisals of the responding pharmacists about their pharmaceutical care capacities, and their respective hospitals valued pharmaceutical care (all ORs > 1.5, P < 0.05). CONCLUSIONS:The study suggested that there is a need to strengthen the pharmacy education, training, and staffing of pharmacists with improved professional skills to offer value-added specialized pharmaceutical care in Chinese public hospitals. Patient-centered and inter-disciplinary interactions in medical practice should be promoted. There is also a need for public hospitals to provide a platform for the achievement of the professional values of high-quality pharmacists at different carrier development stages.

Project description:Health care workers (HCW's) are always at an increased risk of contracting tuberculosis (TB) infection. In Saudi Arabia, Interferon Gamma Release Assay (IGRA) has not been evaluated as a screening tool for latent TB infection (LTBI) among HCW's considering their high demographic diversity. During February 2012 to January 2015 a cross sectional study has been conducted in a tertiary care center with maximum demographically diverse staff population in the capital city-Riyadh. After a short interview and consenting, all the candidates were subjected to tuberculin skin test (TST) and QuantiFERON TB gold In-tube test (QFT). A logistic regression analysis was carried out for establishing the associations between putative risk factors and the diagnostic tests. The candidates were classified according to geographical origin and a detailed analysis was conducted on the impact of their origin towards the results of TST and QFT. Of the 1595 candidates enrolled, 90.6% were BCG vaccinated, female (67.9%) and mainly nurses (53.2%). Candidates with high risk of suspected or confirmed TB patient exposure were 56.1% and 76.5% of them had <10 year's work experience. TST positivity was observed in 503 (31.5%) candidates, while QFT was positive among 399 (25%). Majority of the candidates were non-Saudi (83%) and predominantly (52.4%) from Western Pacific region. Concordant results were obtained in 14.2% of positive cases and 57.7% negative cases. The disagreements between the two tests were relatively high (kappa co-efficient-0.312±0.026, p value- <0.00001) as TST positive/QFT negative discordance was 54.8% while TST negative/QFT positive discordance was 15.7%. Age of the candidates, BCG vaccination, and South East Asian origin were associated with TST positivity while Occupational TB exposure and geographical origin of the candidates were associated with QFT positivity. A regular follow up on recently TST converted candidates showed no progression to active TB. The putative factors associated with the discordance were origin of the candidate (p value <0.001), profession (p value-0.001), BCG vaccination (p value-0.001) and occupational TB exposure level (P value-0.001). The study demonstrated high level prevalence of LTBI among the demographically diverse study candidates. The agreement between QFT and TST was poor, thus QFT alone cannot be recommended in our setting for a routine LTBI screening. Origin of the candidates has strong association with the results of TST and QFT. The discordant results particularly TST negative and QFT positive needs more detailed analysis.
