Background Monitoring the reasons why a considerable number of people do not receive recommended vaccinations allows identification of important trends over time, and designing and evaluating strategies to address vaccine hesitancy and increase vaccine uptake. Existing validated measures assessing vaccine hesitancy focus primarily on confidence in vaccines and the system that delivers them. However, empirical and theoretical work has stated that complacency (not perceiving diseases as high risk), constraints (structural and psychological barriers), calculation (engagement in extensive information searching), and aspects pertaining to collective responsibility (willingness to protect others) also play a role in explaining vaccination behavior. The objective was therefore to develop a validated measure of these 5C psychological antecedents of vaccination. Methods and findings Three cross-sectional studies were conducted. Study 1 uses factor analysis to develop an initial scale and assesses the sub-scales' convergent, discriminant, and concurrent validity (N = 1,445, two German convenience-samples). In Study 2, a sample representative regarding age and gender for the German population (N = 1,003) completed the measure for vaccination in general and for specific vaccinations to assess the potential need for a vaccine-specific wording of items. Study 3 compared the novel scale's performance with six existing measures of vaccine hesitancy (N = 350, US convenience-sample). As an outcome, a long (15-item) and short (5-item) 5C scale were developed as reliable and valid indicators of confidence, complacency, constraints, calculation, and collective responsibility. The 5C sub-scales correlated with relevant psychological concepts, such as attitude (confidence), perceived personal health status and invulnerability (complacency), self-control (constraints), preference for deliberation (calculation), and communal orientation (collective responsibility), among others. The new scale provided similar results when formulated in a general vs. vaccine-specific way (Study 2). In a comparison of seven measures the 5C scale was constantly among the scales that explained the highest amounts of variance in analyses predicting single vaccinations (between 20% and 40%; Study 3). The present studies are limited to the concurrent validity of the scales. Conclusions The 5C scale provides a novel tool to monitor psychological antecedents of vaccination and facilitates diagnosis, intervention design and evaluation. Its short version is suitable for field settings and regular global monitoring of relevant antecedents of vaccination.

Antimicrobial prophylaxis in surgery

This cross-sectional survey examined the pattern of self-medication and factors associated with this practice among medical and pharmacy students in context to Bangladesh. The study used a self-administered questionnaire. A total of 500; 250 medical and 250 pharmacy, students participated in the study. As it is a comparative analysis between the medical and pharmacy students, we used independent t test and Chi square test. The findings indicated that the impact of self-medication is almost similar in medical and pharmacy students. It was found that medical students were more careful about getting advice from a physician or seeking professional help from some healthcare personnel. About the safety of self-medication pharmacy students were more aware than medical students were. The study also showed that female and younger medical or pharmacy students were more aware about self-medication. The current study presents a comprehensive picture of self-medication in medical and pharmacy students in Bangladesh. It is clear from the findings that practice of self-medication is highly prevalent in medical and pharmacy students in the country. This may potentially increase misuse or irrational use of medicines.

Background
The emergence and spread of bacterial resistance to antibiotics is a growing problem worldwide, which presents a significant threat to public health globally in the 21st century. A substantial evidence has shown that the general community plays a role in the increase and spread of antibiotic resistance. The present study was designed to determine knowledge, attitude and practice towards antibiotic use.

Knowledge, attitude and practice towards antibiotic use among the public in Kuwait

Europe is increasingly described as the region in the world with the least confidence in vaccination, and particularly in the safety of vaccines. The aim of this systematic literature review was to gather and summarise all peer-reviewed and grey literature published about determinants of Human Papillomavirus (HPV) vaccine hesitancy in Europe. Ten thematic categories were identified across the 103 articles which were included in the review. Participants from European studies most commonly reported issues with the quantity and quality of information available about HPV vaccination; followed by concerns about potential side effects of the vaccine; and mistrust of health authorities, healthcare workers, and new vaccines. Comparative analyses indicated that confidence determinants differed by country and population groups. This evidence supports the need to develop context-specific interventions to improve confidence in HPV vaccination and design community engagement strategies aiming to build public trust.

HPV vaccination in a context of public mistrust and uncertainty: a systematic literature review of determinants of HPV vaccine hesitancy in Europe

Background The objectives of the study were to investigate the level of knowledge, attitudes, and behaviors regarding antibiotics of the general population in Italy, and to assess the correlates of these outcomes of interest. Methods A cross-sectional survey was conducted on a random sample of 630 parents of students attending nine randomly selected public primary and secondary schools. A self-administered questionnaire included questions on demographic characteristics, knowledge about antibiotic use and resistance, attitudes and behaviors towards antibiotic use, and sources of information. Results A total of 419 parents participated. Only 9.8% knew the definition of antibiotic resistance and 21.2% knew when it was appropriate to use antibiotics. Respondents with higher education, employed, with a family member working in the health care sector, and with no need for additional information on antibiotics were more likely to know the definition of antibiotic resistance. One third (32.7%) self-classified them as users of self-medication with antibiotics and those with a lower self-rated health status, who did not use the physician as source of information on antibiotics, and who have attended a physician in the last year were more likely to use self-medication. One-fourth (22.7%) of those who had never been self-medicated would be willing to take an antibiotic without a prescription of a physician. Respondents were more likely to be willing to take antibiotics without a prescription if they were under 40 years of age, if they had a lower self-rated health status, if they did not know that antibiotics are not indicated for treating flu and sore throat, and if they knew that antibiotics are not indicated for treating colds. Conclusions The survey has generated information about knowledge, attitudes, and behaviors regarding antibiotics in the general population and effective public education initiative should provide practical and appropriate means to change their behavior.

Investigating Italian parents' vaccine hesitancy: A cross-sectional survey.

The aims of this survey were to ascertain pregnant women's level of knowledge and acceptability on the vaccinations and to identify their associations with several characteristics. A cross-sectional study was performed from December 2017 through March 2018 in the geographic area of Naples, Italy. The study used two stages cluster sampling method for selection and recruitment of participants. Data were collected through face-to-face interviews with pregnant women present at the Obstetrics outpatient clinic of the selected hospitals. A total of 358 respondents agreed to be interviewed out of the 405 pregnant women selected. One-fourth knew at least one of the vaccinations recommended during pregnancy and only 2.8% correctly identified all of these. Women who had received information about the vaccinations during pregnancy from general practitioners or gynecologists or other sources and those with at least one child were more likely to know at least one of the recommended vaccinations, whereas women with middle school education were less knowledgeable. None of the women had received tetanus, diphtheria, and acellular pertussis vaccine and only 1.4% the seasonal influenza vaccination. Only 27.9% reported a positive willingness to receive all the recommended vaccinations during pregnancy. Pregnant women would be willing to get all recommended vaccinations if they had at least one child and if they needed additional information, whereas the willingness was significantly lower among women who had reported high school as the highest level of education, who were in the second trimester of pregnancy, and who felt that the recommended vaccines administered during pregnancy were less dangerous for them and for the unborn child. This study suggests important focus points to be taking into account for informing and for implementing education activities on the benefits regarding vaccinations in order to increase the level of knowledge and the uptake in pregnant women.

Vaccination knowledge and acceptability among pregnant women in Italy.

The aims of this study were to assess the knowledge, attitudes, and behaviors towards seasonal influenza and its vaccination among pregnant women. A cross-sectional survey was carried out among a sample of women in the second or third trimester of pregnancy in Italy. The 64.2% of the sample knew that the influenza is more dangerous for pregnant women. Women of older age, Italian, and who had a pregnancy at high-risk were more likely to have this knowledge. This knowledge was lower among women with none, primary or secondary school education. The majority of the respondents considered the vaccine not very useful during pregnancy. Those younger, unmarried, who knew that influenza is more dangerous for pregnant women, who knew that the vaccine could protect them, who reported a higher self-rated health status, and who had received information about influenza and its vaccination were more likely to have a positive attitude toward the usefulness of influenza vaccination in pregnancy. Women with secondary school education and with more than one child revealed a lower perception. Only 9.7% had received the vaccine and 21.4% of those unvaccinated would be willing to receive it. This positive attitude was higher among women with one child, who knew that the vaccine could protect them against the influenza, and who have a positive attitude toward the usefulness of the vaccination during pregnancy. Health educational programs are needed to improve the knowledge about seasonal influenza and vaccination rate in pregnancy.

Seasonal influenza vaccination in pregnant women: knowledge, attitudes, and behaviors in Italy.

This national online cross-sectional survey in Italy assessed primary care pediatricians' (PCPs) attitudes and practices regarding Human papillomavirus (HPV) vaccination and the contribution of several characteristics. The questionnaire was distributed from September 2016 to June 2017 to a random sample of 640 PCPs by email via an internet-link leading to a web-based survey platform (Lime Survey). Only 18.4% of PCPs always recommend the HPV vaccine to 11-12 year old boys. PCPs with longer practice activity, working in solo practice, always recommended the HPV vaccine to 11-12 year old girls, and believed that the vaccine was effective for boys were more likely to always recommend the HPV vaccine. PCPs working in a Region where the vaccination was actively recommended and provided free of charge to 11-12 year old boys had higher odds of recommending vaccination. More than two thirds of PCPs (77.4%) always recommend the HPV vaccine to 11-12 year old girls. PCPs who believed that the vaccine was effective for girls and safe in both boys and girls, who always talk with patients of 11-18 years or their parents about HPV infection and vaccination, and who obtain vaccine information from scientific journals were more likely to always recommend the vaccine. PCPs should employ evidence-based educational strategies in order to achieve a better coverage and to reduce the morbidities and mortality of diseases associated with HPV.
