Abstract
INTRODUCTION Human behavior and understanding of the vaccine ecosystem play a critical role in the vaccination decision-making process. The objective of this study was to understand different cognitive biases that may lead to vaccine acceptance or hesitancy. METHODS The eligibility criteria for this scoping review was vaccination-related cognitive bias studies published in the English language from inception to April 2022 and available on PubMed, Embase, and Google Scholar. It included all geographical locations and individuals of all age groups and excluded studies focusing on (i) clinical trials of vaccines, (ii) vaccine research conduct bias, (iii) cognitive delay, or (iv) statistical biases. The search method also included reviewing references in the retrieved articles. RESULTS Overall, 58 articles were identified, and after screening, 19 were included in this study. Twenty-one cognitive biases with the potential to affect vaccination decision-making were observed. These biases were further grouped into three broad categories: cognitive biases seen while processing vaccine-related information, during vaccination-related decision-making, and due to prior beliefs regarding vaccination. CONCLUSIONS This review identified critical cognitive biases affecting the entire process of vaccination that can influence research and public health efforts both positively and negatively. Recognizing and mitigating these cognitive biases is crucial for maintaining the population's level of trust in vaccination programs around the world.

Understanding the Factors Influencing Health Care Provider Recommendations about Adolescent Vaccines: A Proposed Framework. J Behav Med 2023; 46:356-365. [PMID: 35194726 PMCID: PMC8862696 DOI: 10.1007/s10865-022-00296-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2021] [Accepted: 02/03/2022] [Indexed: 11/17/2022]
Abstract
Health care provider recommendations are among the most important factors influencing parents' decisions to vaccinate their adolescents. However, delivery of high-quality health care provider recommendations for vaccination is not universal. There is wide variation in the strength, timeliness and consistency of the delivery of recommendations for all adolescent vaccines. The factors that influence health care providers' recommendations are multi-level and can be conceptualized in much the same way as vaccine acceptance among parents. Health care providers are influenced by their own attitudes and beliefs about a vaccine and also by the patient they are treating and by the community in which they practice as well as state and national level vaccine policy. We propose a multi-level framework for understanding the factors that influence health care providers' recommendations at the individual, interpersonal and community level to both develop and adapt interventions to improve providers' recommendations.

Abstract
PURPOSE The purpose of this systematic review was to assess how messaging for human papillomavirus (HPV) vaccination to prevent different health outcomes (sexually transmitted infection, anogenital warts ([AGW], and/or cancer) influences intentions or initiation for the vaccine series. METHODS We searched PubMed, MEDLINE, and Embase databases for all previously published articles with an evaluation, discussion, or comparison of messages containing content about HPV infections, AGW, precancers, or cancer through June 3, 2021. Results about messages were summarized by study population and design. RESULTS We identified 25 studies evaluating or comparing messages containing content about HPV-associated outcomes. Study designs included randomized trials (n = 12), cross-sectional surveys (n = 8), and qualitative approaches (n = 5). Few studies directly compared different messages using randomized designs or included vaccination uptake as the outcome. While many studies found support for cancer prevention messages, some studies also found equal or greater support for messages focusing on prevention of sexually transmitted infection/AGW. Variability was observed within and between studied populations (parents/adults, adolescents, young adults, healthcare providers, and adult males) and gender (male and female adolescents). DISCUSSION A greater understanding and deeper attention to myriad health outcomes of HPV infections could increase vaccination uptake in a variety of populations for health promotion across the lifespan.

[PMID: 35696809 DOI: 10.1016/j.ijnurstu.2022.104284] [Citation(s) in RCA: 21] [Impact Index Per Article: 10.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2022] [Revised: 05/17/2022] [Accepted: 05/18/2022] [Indexed: 01/17/2023]
Abstract
BACKGROUND Cognitive and implicit biases of healthcare providers can lead to adverse events in healthcare and have been identified as a patient safety concern. Most research on the impact of these systematic errors in judgment has been focused on diagnostic decision-making, primarily by physicians. As the largest component of the workforce, nurses make numerous decisions that affect patient outcomes; however, literature on nurses' clinical judgment often overlooks the potential impact of bias on these decisions. The aim of this study was to map the evidence and key concepts related to bias in nurses' judgment and decision-making, including interventions to correct or overcome these biases. METHODS We conducted a scoping review using Joanna Briggs methodology. In November 2020 we searched CINAHL, PsychInfo, and PubMed databases to identify relevant literature. Inclusion criteria were primary research about nurses' bias; evidence of a nursing decision or action; and English language. No date or geographic limitations were set. RESULTS We found 77 items that met the inclusion criteria. Over half of these items were published in the last 12 years. Most research focused on implicit biases related to racial/ethnic identity, obesity, and gender; other articles examined confirmation, attribution, anchoring, and hindsight biases. Some articles examined heuristics and were included if they described the process of, and the problems with, nurse decision-making. Only 5 studies tested interventions to overcome or correct biases. 61 of the studies relied on vignettes, surveys, or recall methods, rather than examining real-world nursing practice. This could be a serious oversight because contextual factors such as cognitive load, which have a significant impact on judgment and decision-making, are not necessarily captured with vignette or survey studies. Furthermore, survey and vignette studies make it difficult to quantify the impact of these biases in the healthcare system. CONCLUSIONS Given the serious effects that bias has on nurses' clinical judgment, and thereby patient outcomes, a concerted, systematic effort to identify and test debiasing strategies in real-world nursing settings is needed. TWEETABLE ABSTRACT Bias affects nurses' clinical judgment - we need to know how to fix it.

Abstract
OBJECTIVES Over-the-counter emergency contraception (EC) purchase was legalised in Italy in 2015. Knowledge and access gaps, however, remain. The goal of this study was to explore women's and men's EC informational and access needs. METHODS As part of a larger reproductive study, researchers conducted 42 in-depth interviews (May-June 2019) with English-speaking women and men aged 18-50 years (mean ± standard deviation, 29.1 ± 7.9 years) living in or near Florence, Italy, and using the Italian health care system. Researchers completed qualitative data analysis to identify emergent themes related to EC knowledge, attitudes and access. HyperRESEARCH aided data organisation and analysis. Researchers used a comparative method to contextualise data and identify emergent themes. RESULTS Findings demonstrated that peer communication and experiences served as influential factors in others' EC use. This propagated misinformation, reducing participants' confidence in EC efficacy and safety. Women described the relevance of relationship type in whether to engage men in EC discussion, while men desired an active supportive role. Finally, participants described various messaging and access channels to increase EC knowledge and access. CONCLUSION Findings offer practical recommendations to guide social marketing and behaviour change interventions to increase EC access among women and men in Italy. The utility of pharmacists to individuals wishing to access EC is explored.

Abstract
Immigrant clinicians are vital to population healthcare delivery and therefore population health. One in four physicians in the United States are foreign-born and notably represented in family and pediatric medicine - specialties charged with administering childhood/adolescent vaccines, such as Human Papillomavirus vaccine (HPVV). Our examination suggests there may be unique cultural and socialization factors that influence clinician HPVV recommendation practice; however, immigrant clinicians have not been adequately engaged within the national HPVV agenda. Given the volume and significance of immigrant clinicians, engagement of these clinicians, in both community and nation-wide efforts to increase HPVV, is a necessary step for improving and achieving the national health goal of optimizing HPVV for cancer prevention.

Abstract
BACKGROUND Vaccine hesitancy has been a growing challenge for public health in recent decades. Among factors contributing to vaccine hesitancy, concerns regarding vaccine safety and Adverse Events (AEs) play the leading role. Moreover, cognitive biases are critical in connecting such concerns to vaccine hesitancy behaviors, but their role has not been comprehensively studied. In this study, our first objective is to address concerns regarding vaccine AEs to increase vaccine acceptance. Our second objective is to identify the potential cognitive biases connecting vaccine hesitancy concerns to vaccine-hesitant behaviors and identify the mechanism they get triggered in the vaccine decision-making process. METHODS First, to mitigate concerns regarding AEs, we quantitatively analyzed the U.S. Vaccine Adverse Event Reporting System (VAERS) from 2011 to 2018 and provided evidence regarding the non-severity of the AEs that can be used as a communicable summary to increase vaccine acceptance. Second, we focused on the vaccination decision-making process. We reviewed cognitive biases and vaccine hesitancy literature to identify the most potential cognitive biases that affect vaccine hesitancy and categorized them adopting the Precaution Adoption Process Model (PAPM). RESULTS Our results show that the top frequent AEs are expected mild reactions like injection site erythema (4.29%), pyrexia (3.66%), and injection site swelling (3.21%). 94.5% of the reports are not serious and the average population-based serious reporting rate over the 8 years was 25.3 reports per 1 million population. We also identified 15 potential cognitive biases that might affect people's vaccination decision-making and nudge them toward vaccine hesitancy. We categorized these biases based on the factors that trigger them and discussed how they contribute to vaccine hesitancy. CONCLUSIONS This paper provided an evidence-based communicable summary of VAERS. As the most trusted sources of vaccine information, health practitioners can use this summary to provide evidence-based vaccine information to vaccine decision-makers (patients/parents) and mitigate concerns over vaccine safety and AEs. In addition, we identified 15 potential cognitive biases that might affect the vaccination decision-making process and nudge people toward vaccine hesitancy. Any plan, intervention, and message to increase vaccination uptake should be modified to decrease the effect of these potential cognitive biases.
