COVID-19 has affected all aspects of human life so far. From the outset of the pandemic, preventing the spread of COVID-19 through the observance of health protocols, especially the use of sanitizers and disinfectants was given more attention. Despite the effectiveness of disinfection chemicals in controlling and preventing COVID-19, there are critical concerns about their adverse effects on human health. This study aims to assess the health effects of sanitizers and disinfectants on a global scale. A total of 91,056 participants from 154 countries participated in this cross-sectional study. Information on the use of sanitizers and disinfectants and health was collected using an electronic questionnaire, which was translated into 26 languages via web-based platforms. The findings of this study suggest that detergents, alcohol-based substances, and chlorinated compounds emerged as the most prevalent chemical agents compared to other sanitizers and disinfectants examined. Most frequently reported health issues include skin effects and respiratory effects. The Chi-square test showed a significant association between chlorinated compounds (sodium hypochlorite and per-chlorine) with all possible health effects under investigation (p-value <0.001). Examination of risk factors based on multivariate logistic regression analysis showed that alcohols and alcohols-based materials were associated with skin effects (OR, 1.98; 95%CI, 1.87–2.09), per-chlorine was associated with eye effects (OR, 1.83; 95%CI, 1.74–1.93), and highly likely with itching and throat irritation (OR, 2.00; 95%CI, 1.90–2.11). Furthermore, formaldehyde was associated with a higher prevalence of neurological effects (OR, 2.17; 95%CI, 1.92–2.44). Furthermore, formaldehyde was associated with a higher prevalence of neurological effects (OR, 2.17; 95%CI, 1.92–2.44). The use of sodium hypochlorite and per-chlorine also had a high chance of having respiratory effects. The findings of the current study suggest that health authorities need to implement more awareness programs about the side effects of using sanitizers and disinfectants during viral epidemics especially when they are used or overused.

Health care provider payment schemes consist of a complex set of arrangements used to influence provider behavior towards specific health policy objectives. The study aimed at: 1) providing a structured, comparative overview of current payment schemes within the public health system in selected Central and Eastern European (CEE) countries for different health care providers; 2) identifying and comparing major changes in payment schemes since 2010. Methods included: 1) data collection form development; 2) desk research; 3) national experts' consultations; 4) comparative analysis. The results indicate that the nine CEE countries (Bulgaria, Croatia, Czechia, Estonia, Latvia, Lithuania, Hungary, Poland, and Romania) show numerous similarities in provider payment method mix and in the general direction of the recent changes conducted in this field. Output-based payment methods prevail across all countries and types of providers. Primary health care (PHC) providers are characterized by the most diverse payment method mix. PHC and hospital inpatient care have experienced the most frequent changes in their payment schemes within the last 13 years. These focused mostly on modifying existing payment methods (e.g. detailing payment categories), and applying additional methods to pay for specific services or performance (e.g. fee-for-service, bonus payments). The objectives of conducted change were often similar, thus, there is high potential for a shared, cross-country learning.
