ObjectivesPharmacy staff working in hospitals are at risk of contracting and disseminating influenza. Previous research focuses on community pharmacists’ attitudes towards influenza and vaccination. This survey investigates the beliefs and attitudes of pharmacists and other pharmacy staff working in English Hospitals regarding influenza and the vaccine and how this relates to vaccine uptake.MethodsA self-administered survey was provided to pharmacy staff at three hospitals in the East Midlands of England. Job role, age and vaccination status (vaccinated, intended to be vaccinated, and not vaccinated) were collected alongside ratings of agreement with 20 statements regarding influenza and vaccination using a Likert scale.Results170 pharmacy staff responded; 50.6% had been vaccinated, 17.1% intended to be vaccinated and 32.4% were not vaccinated. Increasing age showed a significant (p = 0.017) positive correlation with increased vaccine uptake as did the beliefs that vaccination protects the individual from influenza (p = 0.049) and that vaccination should be mandatory for NHS staff (p = 0.006). Fear of needles and believing their immune system is strong enough to protect against influenza were negatively correlated with vaccine uptake (p = 0.016 and p = 0.010, respectively). Job role was also strongly correlated with vaccine uptake (p = 0.001), with those holding a pharmacy degree more likely to report being vaccinated or intending to be vaccinated compared to all other pharmacy staff groups.ConclusionsThis is the first survey to focus on vaccine behaviours of all pharmacy staff groups working in hospitals. Current uptake of the influenza vaccine may be increased through engagement of senior pharmacy colleagues and providing education on influenza, vaccines, and vaccination. Similar studies should be undertaken on a larger scale to fully interrogate the differences between pharmacy staff groups.  相似文献

IntroductionVaccination helps to prevent influenza infection and reduce associated costs but the influenza vaccination rate in Texas for adults between the ages of 18 to 64 years old is the lowest in the US. Pharmacies and alternative locations have been shown to help increase vaccination rates but many adults still go unvaccinated.ObjectiveThis research aims to determine the factors associated with obtaining influenza vaccination at the pharmacy compared to non-pharmacy locations in Texas.MethodThis study used pooled Texas Behavior Risk Factor Surveillance System datasets (2014 to 2018) for this assessment. The main outcome variable was categorized into pharmacy and non-pharmacy vaccination locations and analyzed using a logistic regression analysis. Further statistical analysis was done using a multinomial logistic regression after re-categorizing the outcome variable into pharmacy, doctor office, and other locations.ResultBlacks were 63% (AOR 0.37, C.I. 0.26, 0.50) and Hispanics were 38% (AOR 0.62, C.I. 0.48, 0.80) less likely to receive influenza vaccinations at the pharmacy respectively when compared to Whites. Furthermore, those who did not live in a Metropolitan Statistical Area (MSA) were 33% (AOR 0.67, C.I 0.53, 0.84) less likely to receive influenza vaccinations at the pharmacy compared to those who lived in an MSA. While there was no observed difference in the likelihood of receiving influenza vaccination, the unemployed population were 40% (AOR 1.40, C.I 1.15, 1.71) more likely to be vaccinated in the pharmacy compared to the employed population.ConclusionThere is potential for increased utilization of pharmacies as a source of influenza vaccination in Texas. Racial differences exist both for receiving influenza vaccinations and being vaccinated in the pharmacy. Influenza vaccination advocacy and education efforts may be necessary to improve pharmacy-based vaccination in Texas, especially for minorities and rural-dwelling Texans.  相似文献

2020年6月中旬,北京市新发地聚集性新型冠状病毒肺炎(以下简称新冠肺炎)疫情发生,首都医科大学大兴教学医院共确诊新冠肺炎患者65例。通过临时改建隔离留观病房,建立隔离留观病房工作机制与工作流程,探索适宜的会诊方法等措施,保障了隔离留观病房的平稳运行。通过总结、分析疫情期间患者就诊情况及诊治效果,认为聚集性疫情发生后患者的就诊行为有一定特点与规律性,隔离留观病房在新冠肺炎排查、诊治过程中发挥了重要作用。一旦发生新冠肺炎疫情,可根据具体情况设置、运行隔离留观病房。  相似文献

BackgroundThe evidence of pharmacists' current involvement in vaccination services in low- and middle-income countries (LMICs) is uncertain. This study would be a first step to develop vaccination services by investigating community pharmacists’ intention to be involved in PDV services not just during COVID-19 pandemic but also during standard service provision in Turkey which can be taken as an example across LMICs.ObjectiveConsidering the efforts to empower community pharmacists in service provision, the goal of the present study was to develop a structural equation model to explain the “Pharmacist-Driven Vaccination Service Intention Model (PDV-SIM)” by using the theory of planned behavior (TPB).MethodsBased on the constructs of TPB, a measurement tool was developed. Sub-factors of PDV service intention was determined by conducting exploratory factor analysis (EFA). In the second step, confirmatory factor analysis (CFA) was conducted to prove the theoretical structure of the tool. Finally, a model explaining the relationship between observed variables, latent constructs from TPB was developed by SEM analysis.ResultsIn the proposed PDV-SIM, patient related attitude toward PDV services, attitude toward negative consequences of PDV services, and subjective norm about PDV services had an impact on the behavioral intention of community pharmacists. Nevertheless, professional development attitude toward PDV services and perceived behavioral control were not evaluated as determinants of the behavioral intention.ConclusionResults of this study revealed that TPB is appropriate for modelling PDV service intention of community pharmacists. This model can be utilized as a guide to potential pharmacy regulatory bodies and policy makers in their efforts to enable community pharmacists as vaccinators across LMICs.  相似文献

In actual surgical antimicrobial prophylaxis, the anaesthetist administers the drugs at induction of anaesthesia. In the first phase of our qualityofuse intervention study on antimicrobial drugs in a large university hospital, information on the practice of antimicrobial prophylaxis was needed. The staff of 44 anaesthetists was interviewed by means of a questionnaire. Response rate was 36/44 (82%). The anaesthetists' method of administering surgical prophylaxis was rather uniform and inexpensive: cephalosporins were almost exclusively administered by bolus method. The main reason was that infusion was more cumbersome (range 7785%). Communication between surgeon and anaesthetist was reported to be poor, and in two out of three operating departments, orders of prophylaxis transmitted at or after induction accounted for more than 80%. Seventyseven percent of the responders asked the surgeon if prophylaxis was necessary if they were in doubt; 20% responded that they checked it systematically. The data collected by the inquiry proved useful in the process of optimizing surgical prophylaxis in our hospital.  相似文献
