COVID vaccine evaluation of barriers and resources among families of children with diagnosed allergies

Background

We aimed to determine vaccine hesitancy and the main barriers associated with the 2019 novel coronavirus, SARS-CoV-2 (COVID-19) vaccination among families of children diagnosed with food/drug/environmental allergies.

Methods

Between May and June 2021, we approached 146 families seen at the outpatient allergy clinic at the Montreal Children's Hospital and a community allergy practice were invited to complete an anonymous online survey on COVID-19 and vaccination attitudes and behaviour. Uni and multivariable logistic regressions were compared to estimate factors associated with vaccine hesitancy.

Results

Among all patients, 24.1% reported vaccine hesitancy. The large majority of parents (95.2%) believed that vaccines work. The most common barrier to vaccination was fear of adverse side effects (57.0%). One-third of participants (31.5%) reported that a history of food, venom and drug allergy was a contraindication for COVID-19 vaccination. Fifty-nine (60.8%) participants stated that the dissemination of additional information would increase their willingness to be vaccinated. Most (96.9%) parents reported that their children's vaccinations were up to date. Hesitant families were more likely to be parents of children aged 6-10 years, be of Asian descent, report that mRNA vaccines are riskier than traditional vaccines, and report that the vaccine should not be given if the child has a history of allergic reaction to vaccines.

Conclusion

Vaccine hesitancy exists mainly among certain ethnic groups and families with young children. Allergies to food, venom and drug allergy are commonly perceived as contraindications for COVID-19 vaccination. Knowledge translation activities addressing parental concerns will help increase vaccination rates.

Empowering Health Workers to Build Public Trust in Vaccination: Experience from the International Pediatric Association's Online Vaccine Trust Course, 2020-2021

BACKGROUND

The quality of interactions between health workers (HWs) and caregivers is key in vaccine acceptance. To optimize this, HWs need knowledge about best vaccine communication practices in person and on social media. Most pre-service curricula do not include such approaches. COVID-19 necessitated the International Pediatric Association (IPA) to shift from in-person train the trainer workshops to developing an online Vaccine Trust Course to address these gaps.

METHOD

The seven-module, 8-hour Vaccine Trust Course was offered online in seven languages and promoted globally. Course outcomes for participants between September 1, 2020 and September 30, 2021 were assessed using enrollment, participation, and completion data; pre-and post-training surveys of attitudes, knowledge, and practice skills; and follow-up practice surveys 3 months post course completion.

RESULTS

Of the 4,926 participants across 137 countries who registered; 2,381 (48.3 %) started the course, with 1,217 (51.1 %) completing. The majority were 25 - 39 years (57 %), female (57 %), and in pediatrics (70 %); 31 % came from India. 62 % of completers rated course structure/design as excellent, 36 % as good. Over 80 % rated the content as the most valuable aspect. Three months post training, 61 % HWs reported increased empathy towards caregivers, confidence while counseling and increased vaccine acceptance amongst their patients. 21 % identified the course as the only factor in these positive changes.

CONCLUSION

Shifting from face-to-face to online training due to the COVID-19 pandemic helped increase the global reach of HWs course engagement and uptake. Trained HWs reported increased empathy towards caregivers and confidence while counseling and increased patient vaccine acceptance.

Resolving sex and gender bias in COVID-19 vaccines R&D and beyond

The influence of sex and gender in immune response and vaccine outcomes is established in many disease areas, including in COVID-19. Yet, there are notable gaps in the consideration of sex and gender in the analysis and reporting of COVID-19 vaccines clinical trial data. The push for stronger sex and gender integration in vaccines science should be championed by all researchers and stakeholders across the R&D and access ecosystem - not just gender experts. This requires joint action on the tactical framing of customized value propositions (based on stakeholder motivations), the stronger enforcement of existing regulation, tools, and commitments, and aligning the overall agenda to parallel calls on intersectionality, equity diversity and inclusion.

Letting kids play their CARDs (Comfort, Ask, Relax, Distract) to help cope with needle-related fear and pain: Results from user testing

This study examined perceptions of children and parents about a new web-based CARD (Comfort, Ask, Relax, Distract) game that teaches children how to cope with needle-related pain and fear. A convenience sample of 15 child-parent dyads (children, 6-12 years) participated. Children played the game on a handheld device while being virtually monitored. Activity tracking revealed most children engaged with multiple components. Children reported they understood the game, it was easy to play, they learned coping strategies and believed they could implement them. Children reported lower fear of needles after playing. Parents liked the simplicity and variety of game activities. Most children and parents reported they would use the game or its coping strategies for future needles and would recommend the game. In summary, children and parents found the CARD web game acceptable and appropriate. Future studies can evaluate its effectiveness when integrated into upcoming needle procedures like COVID-19 vaccinations.

A qualitative investigation of facilitators and barriers to accessing COVID-19 vaccines among Racialized and Indigenous Peoples in Canada

Structural and systemic inequalities can contribute to susceptibility to COVID-19 disease and limited access to vaccines. Recognizing that Racialized and Indigenous Peoples may experience unique barriers to COVID-19 vaccination, this study explored early COVID-19 vaccine accessibility, including barriers and potential solutions to vaccine access, for these communities in Canada. We conducted semi-structured interviews about challenges to accessing COVID-19 vaccination with Racialized and Indigenous Peoples, including linguistic minorities and newcomers, in Spring 2021, just as COVID-19 vaccines were becoming more widely available in Canada. Participants were purposely selected from respondents to a Canadian national online survey. Three researchers analyzed the interviews for emergent themes using a descriptive content analysis approach in NVivo. At the time of the interview, interview participants (N = 27) intended to receive (n = 15) or had received (n = 11) at least one vaccine dose, or did not state their status (n = 1). Participants described multiple barriers to COVID-19 vaccination that they personally experienced and/or anticipated they or others could experience - including technology requirements, language barriers, lack of identification documentation, and travel challenges - as well as related solutions. These were organized into three broad categories: 1) COVID-19 disease and vaccination information, 2) vaccination booking procedures, and 3) vaccination sites. These structural and systemic barriers during the initial months of vaccine rollout substantially restricted participants' COVID-19 vaccination access, even when they were eager to get vaccinated, and should be addressed early in vaccine rollouts to facilitate optimal uptake for everyone everywhere.

"I don't think there's a point for me to discuss it with my patients": exploring health care providers' views and behaviours regarding COVID-19 vaccination

BACKGROUND

Health care providers' knowledge and attitudes about vaccines are important determinants of their own vaccine uptake, their intention to recommend vaccines, and their patients' vaccine uptake. This qualitative study' objective was to better understand health care providers' vaccination decisions, their views on barriers to COVID-19 vaccine acceptance and proposed solutions, their opinions on vaccine policies, and their perceived role in discussing COVID-19 vaccination with patients.

METHODS

Semi-structured interviews on perceptions of COVID-19 vaccines were conducted with Canadian health care providers (N = 14) in spring 2021. A qualitative thematic analysis using NVivo was conducted.

RESULTS

Participants had positive attitudes toward vaccination and were vaccinated against COVID-19 or intended to do so once eligible (two delayed their first dose). Only two were actively promoting COVID-19 vaccination to their patients; others either avoided discussing the topic or only provided answers when asked questions. Participants' proposed solutions to enhance COVID-19 vaccine uptake in the public were in relation to access to vaccination services, information in multiple languages, and community outreach. Most participants were in favor of mandatory vaccination policies and had mixed views on the potential impact of the Canadian vaccine-injury support program.

CONCLUSIONS

While health care providers are recognized as a key source of information regarding vaccines, participants in our study did not consider it their role to provide advice on COVID-19 vaccination. This is a missed opportunity that could be avoided by ensuring health care providers have the tools and training to feel confident in engaging in vaccine discussions with their patients.

Advanced vaccinology training globally: Update and impact of the COVID-19 crisis

•

A total of 33 advanced vaccinology courses were in existence in 2021.

•

Some vaccinology courses were not sustained since 2018.

•

The number of vaccinology courses has been increasing during the last few years, with courses offered in each WHO region.

•

The COVID-19 pandemic resulted in the cancellation or postponement of some vaccinology courses.

•

Due to the COVID-19 pandemic, an increased number of courses are using an online or hybrid format.

The rapid development of innovations and new technologies, the focus on the life-course approach to immunization and equity, and the prevalent hesitancy towards vaccines requires immunization staff to be well-trained and updated regularly in order to deliver quality immunization services to the public. The need for advanced vaccinology training is therefore paramount. In preparation for a second Global Workshop on Advanced Vaccinology Training that took place in March 2022, this paper presents the results of a survey aiming to provide a thorough update of a landscape analysis on advanced vaccinology courses conducted in 2018 and a look at the impact of the COVID-19 crisis. Thirty-three course organizers responded to a survey to provide information on their respective course. Of those, 17 courses are short courses, 11 post-graduate courses and 5 are Master level courses. Most courses are organized on an annual basis. Even though some courses were not sustained overtime, the number of courses has been increasing during the last few years, and at least one vaccinology course is now being offered in each WHO region. Although the training capacity has increased tremendously, the need still exceeds the capacity and many courses have way more applicants than they can select. The most frequent challenges reported included sustainable funding and identifying faculty. The COVID-19 pandemic impacted the delivery of several vaccinology courses, which have been postponed or reformatted to an online or hybrid training event. An e-portal of the global collaboration has been established to facilitate communication between the different courses and to assist future course participants to identify the most suitable course for their needs.

Feeding Experiences of HIV-Exposed Preterm Infants Among Mothers Living with HIV in Addis Ababa, Ethiopia: A Qualitative Study

Introduction

Providing adequate nutrition to preterm infants who are born to HIV-positive mothers is more challenging due to the mother’s underlying health and nutrition status. The understanding of these issues and active participation of the mothers have a significant role in giving continuous care for HIV-exposed preterm infant. Hence, this study aimed to explore the experience of HIV-positive mothers’ feeding practice of their preterm infants, and health workers to identify barriers and facilitators of feeding HIV-exposed preterm infants.

Methods

A phenomenological qualitative study design was conducted in Addis Ababa, Ethiopia, between May 1, 2016 and March 31, 2017. Mothers who gave birth to HIV-exposed preterm infants at the study sites’ follow-up clinic were traced and invited by the healthcare providers to voluntarily participate in this study. Fifteen in-depth interviews with mothers of HIV-exposed preterm infants and seven key informant interviews with health professionals and policymakers were carried out. The interviews were transcribed and translated and then manually analyzed thematically.

Results

The health education given during antenatal care (ANC) did not consider the feeding practice needs for HIV-exposed preterm infants. Child health status, desire to have a healthy infant, financial constraints and family support were among the influential factors in the feeding practice of HIV-exposed preterm infants mentioned by the study participants. HIV-exposed preterm infant feeding procedure neither has a guideline nor is clearly mentioned in the national HIV guidelines.

Conclusion

The desire to have a healthy infant was a major facilitator for feeding of HIV-exposed premature infants. However, financial constraints majorly limited the option to be only exclusive breastfeeding. This became even more problematic for the mother if the premature infant became ill and could not breastfeed well.

Healthcare providers and caregivers' perspectives on factors responsible for persistent malnutrition of under 5 children in Buhweju district, South Western Uganda; a phenomenological qualitative study

Background

Unacceptably high levels of childhood malnutrition have been registered in all regions of Uganda over the years. Buhweju district alone contributed 46% prevalence of childhood malnutrition to the 47.8% estimated national prevalence for the whole of western Uganda in 2014. This study assessed health provider and caregiver opinions on factors responsible for persistent malnutrition among under five children in Engaju and Nyakishana sub counties.

Methods

In this phenomenological qualitative study, we conducted two key informant interviews and six focus group discussions with Village Health Team members and care takers of under five children in Engaju and Nyakishana sub-counties respectively.to explore their opinions on the factors responsible for persistent malnutrition in Buhweju District in May 2018. Data were thematically analyzed manually and using Atals Ti 7.5.

Results

Historical and geographical challenges, poverty and economic occupation, parental alcoholism and domestic violence as well as inadequate childcare services were identified as factors responsible for persistent malnutrition among under five children in Engaju and Nyakishana sub counties.

Conclusion

Persistent malnutrition in under five children is mainly due to historical and geographical challenges and its associated factors that include poverty and economic occupation, parental alcoholism and domestic violence and inadequate childcare services. Thus literacy education for mothers and young adolescent boys and girls through engaging local leaders, local nongovernmental organizations and Companies operating in the district to contribute to social services provision would limit the domestic violence and increase sensitization on male responsibilities in the children care in Buhweju district.

Vaccination in pregnancy: Challenges and evidence-based solutions

Vaccination in pregnancy (VIP) is dually beneficial - it protects the mother and the baby from tetanus, influenza, and pertussis. VIP uptake is low in many countries. Vaccine hesitancy, defined by the World Health Organization (WHO) as a "delay in acceptance or refusal of vaccination despite the availability of vaccination services" is one of WHO's ten threats to global health per 2019. According to extensive research, mostly from high-income countries (HIC) and limited to tetanus, influenza and pertussis vaccines, lack of provider recommendations, safety concerns, and limitations in access are the main barriers to VIP. Health care provider recommendation is the leading facilitator for VIP across various socioeconomic status groups. Data on strategies to overcome patient, provider, and system barriers to VIP are inconsistent, contradictory, or lacking. Patient-focused research on evidence-based strategies to overcome provider and system barriers is needed. Furthermore, VIP programs require embedded continuous quality improvement to ensure sustainability.

The accuracy of pre-operative (P)-POSSUM scoring and cardiopulmonary exercise testing in predicting morbidity and mortality after pancreatic and liver surgery: A systematic review

Background

Cardiopulmonary exercise-testing (CPET) and the (Portsmouth) Physiological and Operative Severity Score for the enUmeration of Mortality and Morbidity ((P)-POSSUM) are used as pre-operative risk stratification and audit tools in general surgery, however, both have been demonstrated to have limitations in major hepatopancreatobiliary (HPB) surgery.

Materials and methods

The aim of this review is to determine if CPET and (P)-POSSUM scoring systems accurately predict morbidity and mortality. Eligible articles were identified with an electronic database search. Analysis according to surgery type and tool used was performed.

Results

Twenty-five studies were included in the final review. POSSUM predicted morbidity demonstrated weighted O/E ratios of 0.75(95%CI0.57–0.97) in hepatic surgery and 0.85(95%CI0.8–0.9) in pancreatic surgery. P-POSSUM predicted mortality in pancreatic surgery demonstrated an O/E ratio of 0.75(95%CI0.27–2.13) and 0.94(95%CI0.57–1.55) in hepatic surgery. In both pancreatic and hepatic surgery an anaerobic threshold(AT) of between 9 0.5–11.5 ml/kg/min was predictive of post-operative complications, and in pancreatic surgery ventilatory equivalence of carbon dioxide(˙VE/˙VCO2) was predictive of 30-day mortality.

Conclusion

POSSUM demonstrates an overall lack of predictive fit for morbidity, whilst CPET variables provide some predictive power for post-operative outcomes. Development of a new HPB specific risk prediction tool would be beneficial; the combination of parameters from POSSUM and CPET, alongside HPB specific markers could overcome current limitations.

•

Current pre-operative scoring for pancreatic and liver surgery is inaccurate.

•

In pancreatic and liver surgery anaerobic threshold scores were predictive of complications.

•

In pancreatic surgery ventilatory equivalence of carbon dioxide was predictive of mortality.

•

P-POSSUM is inaccurate for predicting mortality and morbidity in pancreatic surgery.

Mandatory immunization: Empirical examination of governance instruments in 28 Global NITAG Network (GNN) countries

Background

In the Global Vaccine Action Plan 2017 Assessment Report, WHO's SAGE noted need to understand ways in which legislation and regulation are used to advance or undermine immunization. The NITAG Environmental Scan Project sought to address this in a pilot study.

Methods

Data was collected via a secure online survey of GNN members (40 countries Sept 2018). Respondents reporting a mandatory element were asked: (1) what vaccinations were required by law; and (2) what population groups were subject to mandates; (3) what grounds, if any, were available for requesting exemptions.

Results

28 (70%) countries responded, representing every WHO region and World Bank income level. While mandatory immunization programs / elements within broader NIPs were relatively common, jurisdictions varied with respect to immunizations required, population groups affected, grounds for exemptions, and penalties for non-compliance. We observed some loose associations with geography and income level. Children were the most common population group subject to mandates at some stage of childhood development (28/28); healthcare workers were second (8/15 (53%)). Sanctions for failure to immunize varied broadly, ranging from no penalty, to loss of access to social services e.g. admission to school, monetary fines, and incarceration. A variance between countries as to how strictly immunization mandates are enforced was noted.

Conclusions

A variety of approaches existed ranging from Narrow/Permissive to Broad/ Inclusive in scope with enforcement mapping loosely to this continuum from Loose/Permissive to Tight/Coercive. Jurisdictions with few/no vaccines mandated, and few/no target groups identified, Loose approach is expected; for those closer to Broad approach, Tighter controls expected. Coercive measures may be 'positive' (vaccination as a gateway to public services, with possible work-arounds), or 'negative' (failure to vaccinate = penalties).

Student Feedback to Tailor the CARD™ System for Improving the Immunization Experience at School

Increasing the comfort of vaccine delivery at school is needed to improve the immunization experience for students. We created the CARD™ (C-Comfort, A-Ask, R-Relax and D-Distract) system to address this clinical care gap. Originally designed for grade 7 students, this study examined the perceptions of grade 9 students of CARD™. Grade 9 students who had experience with school-based immunizations, either as recipients or onlookers (n = 7; 100% females 14 years old) participated. Students answered pre-post surveys, reviewed CARD™ educational materials and participated in a semi-structured focus group discussion. The Consolidated Framework for Implementation Research (CFIR) was used as the framework for analysis of qualitative data. Participants reported positive perceptions of CARD™ educational materials and that CARD™ could fit into the school immunization process. CARD™ improved knowledge about effective coping interventions and was recommended for education of both nurses and students. The results provide preliminary evidence that CARD™ is acceptable and appropriate for implementation in grade 9 school-based immunizations.

Global vaccine action plan lessons learned I: Recommendations for the next decade

The Global Vaccine Action Plan 2011-2020 (GVAP) was developed to realize the ambitions of the Decade of Vaccines - that all individuals and communities enjoy lives free from vaccine-preventable diseases. It included a comprehensive monitoring and evaluation/accountability framework to assess progress towards global targets with recommendations for corrective actions. While many of the GVAP targets are very unlikely to be met by the end of 2020, substantial progress has nevertheless been made, establishing a strong foundation for a successor global immunization strategy, the Immunization Agenda 2030 (IA2030). The Strategic Advisory Group of Experts on immunization has made a series of recommendations to ensure that the lessons learned from GVAP inform the development and implementation of IA2030.

Global Vaccine Action Plan lessons learned III: Monitoring and evaluation/accountability framework

INTRODUCTION

The Monitoring & Evaluation/Accountability (M&E/A) framework of the Global Vaccine Action Plan (GVAP) was used to report progress annually to the World Health Assembly (WHA).

METHODS

Stakeholder feedback was obtained through five reviews consisting of surveys and semi-structured interviews conducted from 2017 to 2019. Participants consisted of individuals involved in the development and implementation of GVAP or its M&E/A process, national immunization managers, academics, representatives of non-governmental organizations, and civil society organizations.

RESULTS

The feedback was mixed and contradictory for some components, though most participants reported that the M&E/A process was a highlight of GVAP and a step in the right direction. Several of the goals and targets were considered aspirational and unrealistic for many countries. There were mixed responses on whether it promoted accountability, especially at the country level.

DISCUSSION

The mixed and contradictory views on the M&E/A processes and its impact suggested a failure of communication about its scope and intent. Though the process, especially the annual reporting to the WHA, kept immunization high on the global agenda, it failed to fully meet the expectations in promoting accountability. Engaging with countries to capture the local context in setting global goals and targets and promoting local M&E/A processes will be important to achieve accountability in the next decade.

Becoming parents again: Challenges affecting grandparent primary caregivers raising their grandchildren

Background

A growing number of Canadian children live in the care of their grandparents, called skip-generation families. Reasons for this include teen pregnancy, death of a parent, mental/physical illnesses, and addictions. These grandparents and grandchildren are at increased risk of physical and mental illness, yet have few resources available to them.

Objective

Our study aims to describe the lived experiences of skip-generation families to better identify their needs.

Methods

We conducted semistructured interviews of grandparent primary caregivers from ten households in our community to chronicle their experiences raising their grandchildren. Participants were recruited by paediatricians using convenience sampling. Interviews were recorded, transcribed, and coded using Atlas Ti software, and classified into themes by consensus.

Results

Five primary themes emerged from the interviews: (1) Changes in family dynamics, (2) Psychosocial impact on grandchild and grandparent, (3) Lack of resources for grandparent caregivers, (4) The challenges of parenting later in life, and (5) Resilience inspired by the love of family. Many participants (n=10) described feeling unsupported after assuming care of their grandchildren and identified a need for additional counselling services, financial support and respite care. All (n=11) highlighted that caring for their grandchildren changed their lives in positive ways.

Conclusion

When grandparents are prioritized as primary caregivers for their grandchildren, our study suggests they receive insufficient community resources to meet their emotional, respite and financial needs. Further research involving this population in Canada is required. Paediatricians can play an essential role in recognizing these vulnerable families and advocating for additional supports and services.

Supporting breastfeeding: Tanzanian men's knowledge and attitude towards exclusive breastfeeding

Background

Exclusive breastfeeding (EBF) is one of the key strategies to ensure infants and young children survive and grow. However, a 2010 study showed that it was only practiced by 50% of Tanzanian women. That study also found that men were rarely supportive; either at home or in the health facilities, due to their personal beliefs or to traditional beliefs and culture of the community. In a report six years later the rate of EBF has decreased to 30%, in one region.

Methods

In this qualitative study, we used focus groups to assess the knowledge and attitudes of 35 men from three villages on the benefits of EBF, the disadvantages of not breastfeeding, and how they can support their partners' breastfeeding. In addition, we assessed how they felt about spending time at home, if they considered handling the infant to be rewarding and whether they helped the mother with home chores. Differences in village infrastructure and characteristics were noted.

Results

Five themes were identified, including traditional roles, and feelings of exclusion/inclusion and resistance. Men felt they needed better information on EBF. They wished that their partners could breastfeed for a longer time, since they realized it improved infant growth and prevented disease; however, they did not have time to remain with the infant at home. Poverty required the men to work for long periods outside the home. As well, the men were not involved with the Reproductive Child Health Clinic (RCHC) except at the time of delivery or for mandatory HIV testing, however, they wanted to be educated together with their partners at the RCHC.

Conclusion

Most men in this study understood that the EBF period was important, and that it broadened their relationship with their partner. EBF, however, could be a challenge for couples because of poverty. Nevertheless, many men wanted to help and to become more involved.

Global vaccinology training: Report from an ADVAC workshop

At a workshop on 7-8 November 2018 the leaders of 26 advanced vaccinology courses met to carry out an extensive review of the existing courses worldwide, in order to identify education gaps and future needs and discuss potential collaboration. The main conclusions of the workshop concerned: opportunities for strengthening and expanding the global coverage of vaccinology training; evaluation of vaccinology courses; updating knowledge after the course; how to facilitate post-course 'cascade' training; developing and sharing best practices; the application of online and innovative approaches in adult education; and how to reduce costs and facilitate wider access to vaccinology training. The importance of collaboration and information exchange through networks of alumni and between courses was stressed. A web platform to provide information about existing courses for potential applicants is needed. Lack of sustainable funding is a constraint for vaccinology training and needs to be addressed.

Vaccine-preventable diseases: Uncommon disease primer for the front-line provider

This practice point provides quick information for front-line health care providers on vaccine-preventable diseases which, given the success of immunization programs in Canada, are now uncommon or rarely seen. These infections can still occur in children and youth from Canada and elsewhere, and their clinical identification has important public health implications. Knowledge of signs and symptoms, immunizing travellers and newcomers to Canada, awareness of outbreaks in-community and elsewhere, and early consultation with an expert in infectious diseases and public health authorities in suspected cases, are key preventive care measures.

The CARD™ System for improving the vaccination experience at school: Results of a small-scale implementation project on student symptoms

BACKGROUND

Many students are afraid of receiving vaccinations at school. We implemented a novel, multifaceted knowledge translation intervention incorporating evidence-based vaccination coping strategies-The CARD™ System (C-Comfort, A-Ask, R-Relax, D-Distract)-and evaluated impact on student attitudes, knowledge, coping strategies used, and symptoms during school-based vaccinations.

METHODS

Mixed methods. Ten schools participated in a controlled clinical trial: five experimental and five control. Experimental School (ES) students completed a knowledge and attitudes survey during an in-class CARD™ educational session prior to school vaccinations and selected coping strategies for upcoming vaccinations. Control School (CS) students received the usual vaccine education lesson, which did not include information about or selection of coping strategies. At all schools and during both vaccination clinic visits (fall and spring), injecting nurses recorded specific coping strategies used, and students independently rated their fear, pain, and dizziness during vaccinations. Focus groups were conducted at five schools after all clinics were completed (three ES, two CS).

RESULTS

ES students had higher knowledge (P<0.001), less fear (P=0.03), and greater willingness to be vaccinated (P=0.001) after the in-class education session. Students rated the education as understandable, sufficient, useful, and that it prepared them for vaccinations. During school vaccination clinics, ES students selected more coping interventions than CS students. There were fewer students with high levels of fear (P=0.008) and dizziness (P=0.04) in the ES group. In round 2, fewer students (P=0.02) in the ES group returned to the clinic postvaccination because they were feeling unwell. ES students participating in focus groups scored higher on their knowledge test (P<0.001) compared with CS students and reported learning and benefitting from CARD™.

DISCUSSION

This small-scale implementation study provides preliminary evidence of the effectiveness of CARD™ in improving vaccination experiences for students at school. Future research is recommended that examines CARD™ in different settings to confirm these results.

The CARD™ System for improving the vaccination experience at school: Results of a small-scale implementation project on program delivery

OBJECTIVE

We conducted a small-scale implementation study that integrated The CARD™ System (C-Comfort, A-Ask, R-Relax, D-Distract)-a multifaceted knowledge translation intervention designed to improve the vaccination experience at school-within the school vaccination program.

METHODS

Mixed methods design, including a controlled clinical trial and focus group interviews. The experimental group included five schools whereby CARD™ was implemented. The control group included five schools whereby no changes were made. Focus groups were held at the end of the school year. For nurses trained in CARD™, additional focus groups were held at CARD™ training and after the first round of vaccine clinic visits. Outcomes included vaccination rate at school and adult stakeholder perceptions.

RESULTS

Altogether, 323 students attended study schools. Fifty-five nurses, school staff, and parents participated in 15 focus groups. The school vaccination rate did not differ (P>0.05) between groups for round 1 clinics (76% versus 77%) or round 2 clinics (68% versus 70%). Participants reported acceptability, appropriateness, feasibility, and satisfaction with CARD™. Experimental group nurses were able to integrate CARD™ within usual activities, including clinic planning, student education, and clinic-day set-up and student vaccinations. Students in experimental schools were described by nurses and school staff as more prepared and less fearful during vaccinations. Nurses reported that CARD™ built on their practice; they had higher confidence in their ability to assess pain and fear and higher satisfaction with their ability to manage it. Nurses also reported improved collaboration with students and with each other. All stakeholder groups recommended continuing CARD™. Some additional time was required, primarily related to clinic planning activities and data collection for study purposes.

CONCLUSION

CARD™ is a promising new approach for improving the delivery of vaccinations at school. Exploration of approaches to increase parental reach and monitoring of vaccination uptake rate over time are recommended.

Stakeholder feedback on The CARD™ System to improve the vaccination experience at school

OBJECTIVE

School-based vaccination programs can be a source of distress for many students due to the pain from the needle injection and related fears. We created a multifaceted Knowledge Translation (KT) intervention to address vaccination and pain, fear, and fainting called The CARD™ System. The objectives were to document acceptability of key tools included in the multifaceted KT intervention and their effectiveness in improving knowledge and attitudes about vaccination pain and fear.

METHODS

Quantitative and qualitative methods were used. Students, school staff, public health nurses, and parents participated in separate focus groups whereby they independently completed a knowledge and attitudes survey and provided structured and qualitative feedback on key KT tools of the multifaceted KT intervention. They then repeated the knowledge and attitudes survey.

RESULTS

Altogether, 22 students (grade 6 and 7), 16 school staff (principals, grade 7 and 8 teachers, resource teachers, secretaries), 10 nurses (injecting, charge, and school nurses), and 3 parents participated. Knowledge test scores increased post-KT tool review: 8.5 (2.1) versus 7.3 (1.9); P<0.001. Attitudes were more positive about the individual nature of pain and fear experience during vaccination. Student fear scores were lower post-tool review: 5.1 (2.9) versus 4.6 (3.0); P<0.001. The majority of the participants reported they understood all the information, the amount was just right and that the information was useful.

DISCUSSION

The KT tools were demonstrated to be acceptable and to improve knowledge. Future research is warranted to determine their impact on student experience during school vaccinations.

Involving stakeholders in informing the development of a Knowledge Translation (KT) intervention to improve the vaccination experience at school

OBJECTIVE

Pain, fear, and fainting management during school-based vaccinations is suboptimal. The objective was to examine stakeholder perceptions of barriers and facilitators to better practices. Method: Six semi-structured focus groups were conducted in Niagara Region, Ontario: two parent groups (n=7); one grade 7 to 8 student group (n=9); two nurse groups (n=12); and one school staff group (n=6). Participants shared perceptions about school vaccination clinics and the implementation of specific strategies and tools. Focus groups were audio recorded and transcribed. The Consolidated Framework for Implementation Research (CFIR) was used as the framework for analysis.

RESULTS

Feedback from stakeholders was categorized into four domains of CFIR: intervention characteristics, inner setting, outer setting, and characteristics of individuals. Intervention characteristics included: vaccine educational materials, vaccination accommodations, distraction techniques, topical anaesthetics, and food. Inner setting factors included: school vaccination procedures, relationships between school staff and nurses, assessment and documentation of student fear, and factors that contribute to a chaotic vaccination clinic. Outer setting factors were: the social environment and addressing parent and student needs. Stakeholder roles were discussed in characteristics of individuals.

CONCLUSION

This study identified elements that can facilitate and challenge pain and fear mitigation tools and strategies; these elements should be considered in the development of a Knowledge Translation (KT) intervention to improve the school vaccination experience.

Piloting The CARD™ System for education of students about vaccination: Does it improve the vaccination experience at school?

OBJECTIVE

Many students are fearful of vaccine injection-associated pain. In prior research, we created Knowledge Translation (KT) tools to address school vaccinations and associated pain, fear, and fainting. The objectives of this pilot implementation project were to determine the acceptability and impact of these KT tools on student knowledge, attitudes, and perceptions of their vaccination experience.

METHODS

Pre-post mixed methods design. Students in an independent school in the Greater Toronto Area, Ontario, participated in two separate focus groups before and after school vaccinations. In both sessions, they independently completed a knowledge and attitudes survey, reviewed three KT tools (two videos and one pamphlet) and then repeated the knowledge and attitudes survey. They provided structured and qualitative feedback about the KT tools and described the impact of the education on the vaccination experience.

RESULTS

Altogether, 11 grade 7 students participated. Knowledge scores were higher post-tool review compared to baseline in the first focus group. There was no significant difference in fear scores and attitudes about getting vaccinated. Qualitative feedback was categorized into two themes: intervention characteristics and characteristics of the school environment. Students reported the KT tools helped them to prepare for vaccination. They used the information on vaccination day to reduce their own fear and pain and to assist peers. They believed all students should view the KT tools. Students reported that teachers and nurses did not do enough to make vaccinations a positive experience. For example, they did not provide a private setting as an option for vaccination and prevented them from using some coping strategies recommended in the KT tools.

DISCUSSION

This study provides preliminary evidence of the acceptability and positive impact of the KT tools on students' vaccination experiences. Future research is recommended that involves inclusion of all students and adults in the KT intervention.

Overview of a Knowledge Translation (KT) Project to improve the vaccination experience at school: The CARD™ System

Background

Students experience fear, pain, and fainting during vaccinations at school. While evidence-based interventions exist, no Knowledge Translation (KT) interventions have been developed to mitigate these symptoms. A multidisciplinary team—the Pain Pain Go Away Team—was assembled to address this knowledge-to-care gap. This manuscript provides an overview of the methodology, knowledge products, and impact of an evidence-based KT program developed and implemented to improve the vaccination experience at school.

Methods

We adapted knowledge and assessed the barriers to knowledge use via focus group interviews with key stakeholder groups involved in school-based vaccinations: students, nurses, school staff, and parents. Next, we developed project-specific goals and data collection tools and collected baseline data. We then created a multifaceted KT intervention called The CARD™ System (C-Comfort, A-Ask, R-Relax, D-Distract) to provide a framework for planning and delivering vaccinations using a student-centred approach. Selected KT tools from this framework were reviewed in additional focus groups held in all stakeholder groups. The multifaceted KT intervention was then finalized and implemented in stages in two projects including grade 7 students undergoing school vaccinations and impact on student outcomes (e.g., symptoms of fear, pain, dizziness) and process outcomes (e.g., utilization of interventions that reduce student symptoms, vaccination rate) were assessed.

Results

Participants reported that improving the vaccination experience is important. Based on participant feedback, an evidence-based multifaceted KT intervention called The CARD™ System was developed that addresses user needs and preferences. Selected KT tools of this intervention were demonstrated to be acceptable and to improve knowledge and attitudes about vaccination in the stakeholder groups. In two separate implementation projects, CARD™ helped grade 7 students prepare for vaccinations and positively impacted on their vaccination experiences. CARD™ improved vaccination experiences for other stakeholder groups as well. There was no evidence of an impact on school vaccination rates.

Conclusion

We developed and implemented a promising multifaceted KT intervention called The CARD™ System to address vaccination-associated pain, fear, and fainting. Future research is recommended to determine impact in students of different ages and in different geographical regions and clinical contexts.

Systematic review searches must be systematic, comprehensive, and transparent: a critique of Perman et al

A high quality systematic review search has three core attributes; it is systematic, comprehensive, and transparent. The current over-emphasis on the primacy of systematic reviews over other forms of literature review in health research, however, runs the risk of encouraging publication of reviews whose searches do not meet these three criteria under the guise of being systematic reviews. This correspondence comes in response to Perman S, Turner S, Ramsay AIG, Baim-Lance A, Utley M, Fulop NJ. School-based vaccination programmes: a systematic review of the evidence on organization and delivery in high income countries. 2017; BMC Public Health 17:252, which we assert did not meet these three important quality criteria for systematic reviews, thereby leading to potentially unreliable conclusions. Our aims herein are to emphasize the importance of maintaining a high degree of rigour in the conduct and publication of systematic reviews that may be used by clinicians and policy-makers to guide or alter practice or policy, and to highlight and discuss key evidence omitted in the published review in order to contextualize the findings for readers. By consulting a research librarian, we identified limitations in the search terms, the number and type of databases, and the screening methods used by Perman et al. Using a revised Ovid MEDLINE search strategy, we identified an additional 1016 records in that source alone, and highlighted relevant literature on the organization and delivery of school-based immunization program that was omitted as a result. We argue that a number of the literature gaps noted by Perman et al. may well be addressed by existing literature found through a more systematic and comprehensive search and screening strategy. We commend both the journal and the authors, however, for their transparency in supplying information about the search strategy and providing open access to peer reviewer and editor's comments, which enabled us to understand the reasons for the limitations of that review.

Are we close to the ideal intravenous fluid?

The approach to i.v. fluid therapy for hypovolaemia may significantly influence outcomes for patients who experience a systemic inflammatory response after sepsis, trauma, or major surgery. Currently, there is no single i.v. fluid agent that meets all the criteria for the ideal treatment for hypovolaemia. The physician must choose the best available agent(s) for each patient, and then decide when and how much to administer. Findings from large randomized trials suggest that some colloid-based fluids, particularly starch-based colloids, may be harmful in some situations, but it is unclear whether they should be withdrawn from use completely. Meanwhile, crystalloid fluids, such as saline 0.9% and Ringer's lactate, are more frequently used, but debate continues over which preparation is preferable. Perhaps most importantly, it remains unclear how to select the optimal dose of fluid in different patients and different clinical scenarios. There is good reason to believe that both inadequate and excessive i.v. fluid administration may lead to poor outcomes, including increased risk of infection and organ dysfunction, for hypovolaemic patients. In this review, we summarize the current knowledge on this topic and identify some key pitfalls and some areas of agreed best practice.

Measuring acute postoperative pain using the visual analog scale: the minimal clinically important difference and patient acceptable symptom state

Background

The 100 mm visual analog scale (VAS) score is widely used to measure pain intensity after surgery. Despite this widespread use, it is unclear what constitutes the minimal clinically important difference (MCID); that is, what minimal change in score would indicate a meaningful change in a patient's pain status.

Methods

We enrolled a sequential, unselected cohort of patients recovering from surgery and used a VAS to quantify pain intensity. We compared changes in the VAS with a global rating-of-change questionnaire using an anchor-based method and three distribution-based methods (0.3 sd , standard error of the measurement, and 5% range). We then averaged the change estimates to determine the MCID for the pain VAS. The patient acceptable symptom state (PASS) was defined as the 25th centile of the VAS corresponding to a positive patient response to having made a good recovery from surgery.

Results

We enrolled 224 patients at the first postoperative visit, and 219 of these were available for a second interview. The VAS scores improved significantly between the first two interviews. Triangulation of distribution and anchor-based methods resulted in an MCID of 9.9 for the pain VAS, and a PASS of 33.

Conclusions

Analgesic interventions that provide a change of 10 for the 100 mm pain VAS signify a clinically important improvement or deterioration, and a VAS of 33 or less signifies acceptable pain control (i.e. a responder), after surgery.

Inter-observer reliability of preoperative cardiopulmonary exercise test interpretation: a cross-sectional study

BACKGROUND

Despite the increasing importance of cardiopulmonary exercise testing (CPET) for preoperative risk assessment, the reliability of CPET interpretation is unclear. We aimed to assess inter-observer reliability of preoperative CPET.

METHODS

We conducted a prospective, multi-centre, observational study of preoperative CPET interpretation. Participants were professionals with previous experience or training in CPET, assessed by a standardized questionnaire. Each participant interpreted 100 tests using standardized software. The CPET variables of interest were oxygen consumption at the anaerobic threshold (AT) and peak oxygen consumption (VO₂ peak). Inter-observer reliability was measured using intra-class correlation coefficient (ICC) with a random effects model. Results are presented as ICC with 95% confidence interval, where ICC of 1 represents perfect agreement and ICC of 0 represents no agreement.

RESULTS

Participants included 8/28 (28.6%) clinical physiologists, 10 (35.7%) junior doctors, and 10 (35.7%) consultant doctors. The median previous experience was 140 (inter-quartile range 55-700) CPETs. After excluding the first 10 tests (acclimatization) for each participant and missing data, the primary analysis of AT and VO₂ peak included 2125 and 2414 tests, respectively. Inter-observer agreement for numerical values of AT [ICC 0.83 (0.75-0.90)] and VO₂ peak [ICC 0.88 (0.84-0.92)] was good. In a post hoc analysis, inter-observer agreement for identification of the presence of a reportable AT was excellent [ICC 0.93 (0.91-0.95)] and a reportable VO₂ peak was moderate [0.73 (0.64-0.80)].

CONCLUSIONS

Inter-observer reliability of interpretation of numerical values of two commonly used CPET variables was good (>80%). However, inter-observer agreement regarding the presence of a reportable value was less consistent.

The next vaccine-autism question: Are school-aged youth with autism spectrum disorder undervaccinated and, if so, why?

Over the past two decades, the words 'autism' and 'vaccination' have often been linked and mired in controversy. In this commentary, we raise a different question about autism spectrum disorder (ASD) and vaccines: Are school-aged youth with ASD undervaccinated and, if so, why? There are several reasons why youth with ASD might be undervaccinated, including: belief in a vaccine-ASD link, challenges faced by youth with ASD when seeking health care and vaccine hesitancy factors that affect the general population. Possible undervaccination in this group is concerning given the prevalence of ASD and the key role of vaccinations in preventing infectious diseases. More research is needed to establish definitively whether youth with ASD are undervaccinated and to understand facilitators and barriers to vaccination for this population. This would help public health officials to develop and implement targeted policy and practice changes to increase vaccination uptake in youth with ASD, thereby increasing immunization equity.

CT chest abdomen pelvis doses in Scotland: has the DRL had its day?

OBJECTIVE

This article reports on a pilot study designed to collect dose data representative of current CT chest abdomen pelvis (CAP) practice in Scotland, make any immediately obvious interventions and to identify if the current UK diagnostic reference level (DRL) of 940 mGy cm is still appropriate. The aims are to identify if a Scotland-wide picture archiving and communication system (PACS)-based dose audit of a number of CT examinations is likely to have value in terms of optimization of patient doses and to comment on the significance of the results in terms of future optimization strategies.

METHODS

Dose audit of CT CAP examinations at 32 different scanner sites across Scotland using accepted data collection and analysis methods. The minimum sample size was 30.

RESULTS

RESULTS indicate that CT CAP doses are lower than those previously reported (median, 800 mGy cm, 75th percentile 840 mGy cm) but follow a distribution that is not in keeping with the concept of DRLs as presently understood or implemented.

CONCLUSION

There is value in a PACS-based dose audit project to provide serial snapshots of patient doses as optimization efforts take place and to revise current knowledge about CT doses. In our opinion, the results call into question whether DRLs or the concept of "achievable dose" are suitable for devising optimization strategies once a certain degree of optimization has taken place.

ADVANCES IN KNOWLEDGE

The results reported here suggest that it may be time to take a different approach to optimization, concentrating on tools that are more refined than the DRL, which may have become more of a compliance tool than an aid to optimization.

Montreal prognostic score: estimating survival of patients with non-small cell lung cancer using clinical biomarkers

Background:

For evidence-based medical practice, well-defined risk scoring systems are essential to identify patients with a poor prognosis. The objective of this study was to develop a prognostic score, the Montreal prognostic score (MPS), to improve prognostication of patients with incurable non-small cell lung cancer (NSCLC) in everyday practice.

Methods:

A training cohort (TC) and a confirmatory cohort (CC) of newly diagnosed patients with NSCLC planning to receive chemotherapy were used to develop the MPS. Stage and clinically available biomarkers were entered into a Cox model and risk weights were estimated. C-statistics were used to test the accuracy.

Results:

The TC consisted of 258 patients and the CC consisted of 433 patients. Montreal prognostic score classified patients into three distinct groups with median survivals of 2.5 months (95% confidence interval (CI): 1.8, 4.2), 8.2 months (95% CI: 7.0, 9.4) and 18.2 months (95% CI: 14.0, 27.5), respectively (log-rank, P<0.001). Overall, the C-statistics were 0.691 (95% CI: 0.685, 0.697) for the TC and 0.665 (95% CI: 0.661, 0.670) for the CC.

Conclusion:

The MPS, by classifying patients into three well-defined prognostic groups, provides valuable information, which physicians could use to better inform their patients about treatment options, especially the best timing to involve palliative care teams.

Cultural bias in the AAP's 2012 Technical Report and Policy Statement on male circumcision

The American Academy of Pediatrics recently released its new Technical Report and Policy Statement on male circumcision, concluding that current evidence indicates that the health benefits of newborn male circumcision outweigh the risks. The technical report is based on the scrutiny of a large number of complex scientific articles. Therefore, while striving for objectivity, the conclusions drawn by the 8 task force members reflect what these individual physicians perceived as trustworthy evidence. Seen from the outside, cultural bias reflecting the normality of nontherapeutic male circumcision in the United States seems obvious, and the report's conclusions are different from those reached by physicians in other parts of the Western world, including Europe, Canada, and Australia. In this commentary, a different view is presented by non-US-based physicians and representatives of general medical associations and societies for pediatrics, pediatric surgery, and pediatric urology in Northern Europe. To these authors, only 1 of the arguments put forward by the American Academy of Pediatrics has some theoretical relevance in relation to infant male circumcision; namely, the possible protection against urinary tract infections in infant boys, which can easily be treated with antibiotics without tissue loss. The other claimed health benefits, including protection against HIV/AIDS, genital herpes, genital warts, and penile cancer, are questionable, weak, and likely to have little public health relevance in a Western context, and they do not represent compelling reasons for surgery before boys are old enough to decide for themselves.
