Significant proportion of acute hepatitis B in Poland in 2010-2014 attributed to hospital transmission: combining surveillance and public registries data.

ABSTRACT: BACKGROUND:Efficient control of acute hepatitis B requires identification of current transmission routes. Countries in Central-Eastern Europe including Poland attribute an important fraction of cases to nosocomial transmission, as opposed to Western European countries. However, due to possible multiple exposures during the incubation time such assignment may be debatable. This study aimed at assessing of most affected groups and current transmission pattern of acute hepatitis B. METHODS:We investigated exposures reported by acute hepatitis B cases notified to routine surveillance system in Poland in 2010-2014 in comparison to data on hospitalization rates in general population. RESULTS:Hospitalization during incubation time significantly increased the risk of HBV infection (RR 3.13, 95%CI 2.58-3.80). Overall hospitalization population attributable risk (PAR%) was 25.7% (95% CI 20.3%-31.1%) as compared to 35% of acute cases assigned to hospital transmission in surveillance database. PAR% increased from 9.5% (1.12%-17.8%) in the age group 25-34 to 41.1% (28.2% - 53.9%) among those 65 +. In addition, cases

Project description:INTRODUCTION:The All Causes of Death Surveillance (ACDS) system was used to measure smoking-attributed mortality by inserting questions on smoking on death certificates. Smoking status information of the deceased has been routinely collected in death certificates since 2010. We describe a death registry-based case-control study using smoking and cause-of-death data for the period 2010-15. METHODS:From 2010, three questions about the smoking status of the deceased were inserted in a revised death certificate: 1) Smoking status (current smoker, quit smoking, never smoker); 2) Number of cigarettes per day smoked; and 3) Number of years of smoking. A data-accuracy survey of 1788 telephone interviews of the family of the deceased was also conducted. Smoking habits (current/ex-smoker vs non-smoker) were compared in study cases (persons who died of lung cancer and other diseases known to be caused by smoking) and the controls (never smokers). Multivariate logistic regression analysis was conducted to estimate relative risks, RR (odds ratios) for smoking-attributed mortality, for lung cancer and all causes of death related to smoking, adjusted for 5-year interval age groups, education, marital status, and year of death. RESULTS:During the study period (2010-15), the annual crude death reporting rates ranged from 6.5‰ to 7.0‰. The reporting rates of smoking status, smoking history and the number of cigarettes smoked daily were 95.5%, 98.6% and 98.6%, respectively. Compared to never smokers, the RR of ever smoking in males was 1.38 (95% CI: 1.33-1.43) for all causes of smoking-related deaths and 3.07 (95% CI: 2.91-3.24) for lung cancer, while in females the values were 1.46 (95% CI: 1.39-1.54) for all causes of smoking-related deaths and 4.07 (95% CI: 3.81-4.35) for lung cancer. The results in Tianjin are in accord with published results from previous studies. CONCLUSIONS:Levels and trends in smoking attributed mortality can be measured at low cost by using the stable, complete and effective ACDS system in Tianjin.
