Recommending COVID-19 Vaccines to Patients: Practice and Concerns of Frontline Family Doctors

Investigating practices and difficulties in communicating with patients about COVID-19 vaccination among healthcare workers in Italy

The aims of this cross-sectional study were to understand the healthcare workers' (HCWs) practices and difficulties in communicating with patients about COVID-19 vaccinations, to investigate the factors associated, and to identify targets to improve the efficacy of the COVID-19 immunization strategy. Questionnaires were administered between November 2021 and March 2022 in three immunization centers in Italy. More than half of HCWs (56.8%) reported to always recommend COVID-19 vaccination to their patients, and the recommendations for other vaccinations were provided by 50.4% of the participants. Physicians/medical residents, males, and those who recommended other vaccinations to their patients were more likely to always recommend COVID-19 vaccination. The participants' perception of difficulties in communicating with patients about COVID-19 vaccination and the impact of sources of information on patients' knowledge about vaccination, explored using a ten-point Likert-type scale, resulted in a mean value of 6.3 and 7.9, respectively. A higher level of perception regarding difficulties in communicating with patients was more likely to be found among nurses/midwives and younger HCWs. It is important to reduce HCWs' perceived gap regarding difficulties in communicating with patients, supporting them through health policy to recommend vaccinations, and engaging them in increasing uptake rates.

Ten pressure points in primary care during COVID-19: findings from an international narrative review

BACKGROUND

Strong primary care (PC) services are the foundation of high-performing health care systems and can support effective responses to public health emergencies. Primary care practitioners (PCPs) and PC services played crucial roles in supporting global health system responses to the COVID-19 pandemic. However, these contributions have come at a cost, impacting on PC services and affecting patient care. This secondary analysis of data from an integrative systematic review across international PC settings aimed to identify and describe burdens and challenges experienced by PCPs and PC services in the context of their contributions to COVID-19 pandemic responses.

METHODS

We conducted an integrative systematic review and narrative analysis, searching PubMed/Medline, Scopus, Proquest Central and Cochrane Database of Systematic Reviews, plus reference lists of key publications. Included studies were published in peer-reviewed English or Chinese language journals, and described collective responses to COVID-19 undertaken in PC settings or by PCPs. Narrative data regarding impacts on PC services and challenges experienced by PCPs were extracted and analysed using inductive coding and thematic analysis.

RESULTS

From 1745 screened papers 108, representing 90 countries, were included. Seventy-eight contained data on negative impacts, challenges or issues encountered in PC. Ten 'pressure points' affecting PC during COVID-19 were identified, clustered in four themes: demand to adopt new ways of working; pressure to respond to fluctuating community needs; strain on PC resources and systems; and ambiguity in interactions with the broader health and social care system.

CONCLUSIONS

PCPs and PC services made critical functional contributions to health system responsiveness during the COVID-19 pandemic. However, both practitioners and PC settings were individually and collectively impacted during this period as a result of changing demands in the PC environment and the operational burden of additional requirements imposed on the sector, offering lessons for future pandemics. This study articulates ten empirically derived 'pressure points' that provide an initial understanding of burdens and demands imposed on the international primary care sector during the COVID-19 pandemic. The impact of these contributions should inform future pandemic planning, guided by involvement of PCPs in public health preparedness and policy design.

Is there a relationship between attitudes of general practitioners/family doctors and attitudes of their patients regarding industry-sponsored clinical investigations? A cross-sectional survey in a convenience sample of doctors and patients across nine European countries

AIM

To assess the relationship between the attitudes of general practitioners/family medicine doctors (GP/FD) and of their patients toward industry-sponsored clinical research.

METHODS

A cross-sectional survey included volunteer GPs/FDs who then enrolled and interviewed their patients. Data were analyzed in hierarchical models (patients nested in GPs/FDs, nested in countries/regions).

RESULTS

A total of 201 GPs/FDs from nine European countries responded to the invitation and enrolled 995 of their patients. We observed mild associations between some of the GPs/FDs' attitudes (general opinion on sponsored clinical studies, appreciation of the general values of such studies, views about the importance of participant protection/privacy) and some of the patients' attitudes (appreciation of the general values and of risks associated with sponsored clinical studies, importance assigned to potential personal benefits from participation). We observed no association between GPs/FDs' attitudes and patients' willingness to participate in such studies. However, willingness to participate increased with higher patients' appreciation of the general values of sponsored studies, decreased with higher patients' appreciation of associated risks, and showed a quadratic trend across the levels of importance assigned by patients to potential personal benefits (willingness was higher when the assigned importance was very low or very high). More importance to GP/FD's advice in this respect was assigned by patients who assigned more importance to potential personal benefits, who were better educated, and who resided in rural/suburban dwellings.

CONCLUSIONS

In the present convenience sample, lay-person attitudes about and willingness to participate in industry-sponsored clinical studies were associated with the attitudes of their GPs/FDs.

COVID-19 Vaccination Acceptance and Hesitancy in Healthcare Workers and the General Population: A Systematic Review and Policy Recommendations

INTRODUCTION

The COVID-19 pandemic challenged the scientific community to find and develop a vaccine to fight the disease. However, problems with achieving high vaccine coverage have emerged, even among high-risk groups such as healthcare workers (HCWs).

OBJECTIVE

The objective of this study is to examine factors that influence HCW's and the general population's adherence to COVID-19 vaccination and national policies to vaccinate HCWs and other target groups.

METHODS

This study implemented a systematic review. The eligibility criterion for inclusion was being a HCW, target population for COVID-19 vaccination, or general population. Vaccination was the target intervention, and the COVID-19 pandemic was the context. We selected publications published between 1 January 2020 and 31 March 2022. Qualitative synthesis used a meta-aggregation approach.

RESULTS

Nineteen articles were included in the review, with study samples varying from 48 to 5708 participants. Most of the evidence came from cross-sectional and qualitative studies. The main findings were related to vaccine hesitancy rather than acceptance. Factors associated with HCW vaccine hesitancy included subjective feelings such as safety concerns, rapid vaccine development, and insufficient testing. Countries have adopted few public policies to address this problem, and the main concern is whether to enforce vaccination and the extent to which measures are legal.

CONCLUSION

The quality of the evidence base remains weak. Skepticism, mistrust, and hesitancy toward vaccination are global issues that can jeopardize vaccination coverage.

Preference for human papillomavirus vaccine type and vaccination strategy among parents of school-age girls in Guangdong province, China

In China, the human papillomavirus (HPV) vaccination coverage among age-eligible girls is rather low, and parent's attitude often plays a determinant role in their girls' HPV vaccination. To accelerate HPV vaccination coverage, several cities and Guangdong province in China offered different HPV vaccine types with different reimbursement methods. In April 2022, we conducted a province-wide survey to investigate parents of children aged 9-15 in Guangdong province, and analyzed factors associated with their preference for HPV vaccine type and vaccination strategy. Of the 4,967 surveyed respondents, 2,610 (58.1%) have not yet vaccinated their children. Among these parents, 67.9% preferred to vaccinate their children with the nine-valent vaccine, while only 8.1% preferred the quadrivalent vaccine and 7.4% preferred the bivalent vaccine. More parents preferred fixed subsidies with free choices of HPV vaccine type over the domestic bivalent vaccine provided by the government (58.1% vs. 39.3%). The multinomial logistic regression showed that parents' relationship with children, educational level, household income, and vaccination status were significantly associated with parents' preference for HPV vaccine type. Parent's relationship with children, workplace, household income, vaccination status, and age of children, were significantly associated with parents' preference for HPV vaccination strategy. Our findings suggest that policymakers may consider adjusting the current vaccination strategy by offering more vaccination choices. More health education on HPV vaccine and vaccination should also be provided to parents of age-eligible girls. Future research should examine which HPV vaccination strategy is more effective in promoting HPV vaccine uptakes in China.

Determinants of COVID-19 Vaccine Acceptability among Healthcare Workers in Kenya-A Mixed Methods Analysis

Healthcare workers (HCWs) were a priority group for COVID-19 vaccination. Adopting the World Health Organization's 3C and the expanded 5C vaccine hesitancy models, we assessed the factors associated with COVID-19 vaccine acceptability among HCWs in Kenya. In a mixed methods study, respondents were from eight selected counties across the country. An online survey (n = 746), key informant interviews (n = 18) and focus group discussions (n = 3) were conducted. The data were analyzed concurrently. Quantitative data showed that all the 3C antecedents were strong predictors of vaccine acceptability. The association of vaccine acceptability was strongest with convenience (aOR 20.13, 95% CI 9.01-44.96), then complacency (aOR 10.15, 95% CI 4.63-22.21) and confidence (aOR 6.37, 95% CI 2.90-14.02). Marital status was a significant independent factor associated with vaccine acceptability (aOR 2.70, 95% CI 1.20-6.08). Qualitatively, convenience presented as the no-cost availability of vaccines at the health facilities, whereas non-complacency manifested from the first-hand observed experience of COVID cases, and the need to protect oneself and family members. Confidence was mainly attributed to increased knowledge, resulting from multiple training sessions and trust in regulatory authorities. Other social factors including workplace pressure, religion and misinformation had a role in influencing HCW vaccination decisions. In the background of a pandemic, the 3C model is a strong predictor of vaccine acceptability, and making the vaccines easily available and convenient to HCWs significantly impacts their uptake.

Predictors of COVID-19 vaccination hesitancy in China: a meta-analysis

OBJECTIVES

This study aimed to examine predictors and moderators of COVID-19 vaccine hesitancy in Chinese cultural contexts.

STUDY DESIGN

A meta-analysis and meta-regression analyses were conducted to examine the associations between predictors and vaccine hesitancy as well as moderators that may impact these associations.

METHODS

We searched relevant articles from January 1, 2020, to May 12, 2022, in the databases of Web of Science, PubMed, ProQuest, ProQuest Dissertations & Theses Global and CNKI. Weighted average effect sizes (e.g., odds ratio) and 95% confidence intervals were computed in Comprehensive Meta-Analysis 3.0 using random-effects models. Heterogeneity tests were conducted prior to moderation analyses.

RESULTS

Results from 161 studies in 73 published articles (N = 705,957) were meta-analyzed. Perceived risk of COVID-19 infection, health status, medical workers' recommendation, recommendations from family and friends, and vaccine coverage among relatives and friends were significantly associated with COVID-19 vaccine hesitancy in Chinese cultural contexts. Participant age, operationalization of vaccine hesitancy, and the time of each study exerted significant moderation effects.

CONCLUSIONS

Both individual and relational factors influence vaccine hesitancy in Chinese cultural contexts Future vaccine promotion initiatives should focus on risk perceptions as well as influence from medical professionals, family and friends.

Effect of Inactivated and mRNA COVID-19 Vaccination on Thyroid Function Among Patients Treated for Hyperthyroidism

CONTEXT

Reports of thyroid dysfunction following COVID-19 vaccination included cases of relapse of Graves' disease and worsening of pre-existing Graves' disease. Little is known about the thyroid-specific outcomes among patients treated for hyperthyroidism who have received COVID-19 vaccination.

OBJECTIVE

Among patients treated for hyperthyroidism, we evaluated factors associated with not receiving the COVID-19 vaccination and whether COVID-19 vaccination was associated with thyroid function instability.

METHODS

We included consecutive patients treated for hyperthyroidism attending the thyroid clinic at a teaching hospital between January and September 2021. They were categorized into vaccinated and unvaccinated groups. The index date was the date of first-dose vaccination for the vaccinated group, and the first date of attendance in the inclusion period for the unvaccinated group. They were followed up until March 2022 or occurrence of thyroid function instability (worsening of thyroid function/increase in antithyroid drug dosage), whichever was earlier.

RESULTS

A total of 910 patients were included (mean age 51.6 years; 82.1% female). Of these, 86.2% had Graves disease and 67.3% were vaccinated (67.3% BNT162b2; 30.6% CoronaVac; 2.1% heterologous). Abnormal thyroid function and cardiovascular comorbidities were independently associated with unvaccinated status. Upon median follow-up of 5.3 months, thyroid function instability occurred in 15.9% of patients. COVID-19 vaccination did not increase risks of thyroid function instability (hazard ratio 0.78, 95% CI 0.56-1.09, P = .151); this was consistent in Graves disease, both types of vaccines, and regardless of whether baseline thyroid function was normal. Twenty-seven patients overtly thyrotoxic at the time of vaccination received COVID-19 vaccines without triggering a thyroid storm or difficulty in subsequent thyroid function control.

CONCLUSION

Among patients treated for hyperthyroidism, abnormal thyroid function was a factor predicting unvaccinated status. Our results should encourage patients treated for hyperthyroidism to receive COVID-19 vaccination to protect themselves from adverse outcomes and potential long-term sequelae of COVID-19.

Models of determinants of COVID-19 vaccine hesitancy in non-pregnant and pregnant population: Review of current literature"

Vaccination has proven to be the most effective tool in controlling the COVID-19 pandemic. While pregnant individuals are considered to be a high-risk population and are more likely to experience adverse effects from COVID-19, vaccination rates among pregnant individuals are significantly lower than in the general population. The Health Belief Model (HBM), Theory of Planned Behavior (TPB), 3C model, 5C model, and 5A model have been used to assess vaccination hesitancy behaviors. In this paper, we review the use of each of these models to address vaccine hesitancy, with a focus on the pregnant population and the COVID-19 vaccine. The HBM, TPB, 3C model, and 5C model have demonstrated great versatility in their ability to evaluate, explain, and modify vaccine hesitancy and behavior. Up to date, the HBM and 3C models appear to be the most effective models to study and address vaccination hesitancy within the pregnant persons.

Pertussis Prevalence in Adult Population in Greece: A Seroprevalence Nationwide Study

The reported cases of pertussis vary considerably globally. In the present nationwide study, we aimed to record the Bordetella pertussis prevalence in Greece by measuring serum IgG specific antibody levels to pertussis toxin (anti-PT IgG). General practitioners and laboratories participated in this study from 12 regions of Greece. A geographically stratified sampling plan based on regional units (NUTS level 2) was applied in order to produce a representative sample, taking into consideration age group (30−39, 40−49, 50−59, 60−69, 70−79 and 80+) and sex. In total, 1169 subjects participated in the study. The percentage of participants with anti-PT IgG antibodies higher than 50 IU/mL was 3.7%. The levels of anti-PT IgG antibodies of total sample ranged between 1.46 IU/mL to 126.60 IU/mL, with mean 17.74 IU/mL and standard deviation 14.03 U/mL (p-value < 0.001). The total seroprevalence of Greek regions for pertussis disease varied significantly among prefectures. The region with the highest seroprevalence was Peloponnese 21.3%, followed by the region of Central Greece 15.3%. The proportion of adults who have pertussis specific antibodies <50 IU/mL has been >90%, suggesting that a large number of adults may be vulnerable to infection of pertussis despite well-established vaccination programs in Greece. Despite the fact that vaccination reduced the number of reported pertussis cases in the last decades in Greece, our seroprevalence study may indicate that the herd immunity level among Greek adults is suboptimal.

Vaccine Resistance and Hesitancy among Older Adults Who Live Alone or Only with an Older Partner in Community in the Early Stage of the Fifth Wave of COVID-19 in Hong Kong

Vaccination is an effective way in providing protection against COVID-19 infection and severe outcomes. However, vaccine resistance and hesitancy are a great concern among vulnerable populations including older adults who live alone or only with an older partner. This study examined their vaccination status and reasons and associated factors of vaccine resistance and hesitancy. A cross-sectional study was conducted among older adults living alone or only with an older partner in communities in Hong Kong. Participants were interviewed between October 2021 and February 2022. Logistic regression analyses were employed to examine factors associated with vaccine resistance and hesitancy. Of the 2109 included participants, the mean age was 79.3 years (SD 7.6), 1460 (69.2%) were female, 1334 (63.3%) lived alone, and 1621 (76.9%) were receiving social security support. The vaccine uptake, non-uptake (i.e., resistance), and hesitancy rates were 50.1%, 34.4%, and 15.5%, respectively. The top four reasons for vaccine resistance and hesitancy were “Not feeling in good health” (27%), “Worry about vaccine side effects” (18%), “Feeling no need” (10%), and “Lack of recommendation from doctors” (9%). Vaccine resistance and hesitancy was significantly associated with older age, living alone, more chronic conditions, fewer types of social media use, and lower self-rated health status. Similar associations can be observed in their separate analysis for vaccine resistance and vaccine hesitancy, and ever hospital admission over the past 6 months was additionally related to vaccine hesitancy. Older people who live alone or only with an older partner had a low vaccination rate. Poor health or worry about vaccine side effects were the most common reasons for their vaccine resistance and hesitancy. Actions are greatly needed to improve the uptake rate among this vulnerable population, especially those who were older, have poorer health, and use less social media.

COVID-19 vaccination: Is it a matter of concern?

Background

COVID-19 vaccination is still a matter of concern among the public since its inception. Primary care physicians being in prime position can share accurate and ample information about COVID-19 vaccination so we estimated proportion and determinants of adverse events following immunization (AEFI) with Covishield vaccine, vaccination and reasons of non-vaccination.

Methods

A cross-sectional study was conducted from January to April 2021. Data collection was done by using data capture tool Epicollect-5. Regression analysis was performed to evaluate the association of AEFI and vaccine acceptance with various demographic variables.

Results

Of 520 subjects, 408 got vaccinated, and of these 125 (30.6%) developed AEFI. Females without AEFI had lower median age than females having AEFI. Only religion (aOR = 5.311; 95% CI: 1. 216-23.1) was significantly associated with AEFI. Education (aOR = 0.399; 95% CI: 0. 199-0.799), marital status (aOR = 0.459; 95% CI: 0. 245-0.858), and religion (aOR = 3.874; 95% CI: 1. 96-7.648) were significantly associated with vaccination. Most common local AEFIs were inflammation (46; 36.8%) followed by lump (10; 8%) at the site of injection. Most common systemic AEFI were fever (87; 69.6%), feeling unwell (65; 52%), generalized weakness/fatigue (30; 20%), tiredness (26; 20.8%), flu-like symptoms (12; 9.6%), dizziness (10; 8%), headache (8; 6.4%) and gastrointestinal events (7; 5.6%).

Conclusion

Most of the AEFI were mild and transient, resolved without any medical management. This study warrants active reporting of AEFI, public release of safety, and efficacy data. Primary care physicians can play a pivotal role by targeted awareness campaigns and trust-building activities to alleviate fear and anxiety related to vaccine.

Safety of Inactivated and mRNA COVID-19 Vaccination Among Patients Treated for Hypothyroidism: A Population-Based Cohort Study

Background: Thyroiditis and Graves' disease have been reported after coronavirus disease 2019 (COVID-19) vaccination. We evaluated the risks of adverse events after COVID-19 vaccination among patients treated for hypothyroidism. Methods: In this retrospective population-based cohort study of Hong Kong Hospital Authority electronic health records with the Department of Health vaccination records linkage, levothyroxine (LT4) users were categorized into unvaccinated, vaccinated with BNT162b2 (mRNA vaccine), or CoronaVac (inactivated vaccine) between February 23, 2021, and September 9, 2021. Study outcomes were dosage reduction or escalation in LT4, emergency department (ED) visit, unscheduled hospitalization, adverse events of special interest (AESI) according to the World Health Organization's Global Advisory Committee on Vaccine Safety, and all-cause mortality. Inverse probability of treatment weighting for propensity score was applied to balance baseline patient characteristics among the three groups. Hazard ratios (HR) were estimated using Cox regression models. Patients were observed from the index date until the occurrence of study outcome, death, or censored on September 30, 2021, whichever came first. Results: In total, 47,086 LT4 users were identified (BNT162b2: n = 12,310; CoronaVac: n = 11,353; and unvaccinated: n = 23,423). COVID-19 vaccination was not associated with increased risks of LT4 dosage reduction (BNT162b2: HR = 0.971 [confidence interval; CI 0.892-1.058]; CoronaVac: HR = 0.968 [CI 0.904-1.037]) or escalation (BNT162b2: HR = 0.779 [CI 0.519-1.169]; CoronaVac: HR = 0.715 [CI 0.481-1.062]). Besides, COVID-19 vaccination was not associated with a higher risk of ED visits (BNT162b2: HR = 0.944 [CI 0.700-1.273]; CoronaVac: HR = 0.851 [CI 0.647-1.120]) or unscheduled hospitalization (BNT162b2: HR = 0.905 [CI 0.539-1.520]; CoronaVac: HR = 0.735 [CI 0.448-1.207]). There were two (0.016%) deaths and six (0.062%) AESI recorded for BNT162b2 recipients, and one (0.009%) and three (0.035%) for CoronaVac recipients, respectively. Conclusions: BNT162b2 or CoronaVac vaccination is not associated with unstable thyroid status or an increased risk of adverse outcomes among patients treated for hypothyroidism in general. These reassuring data should encourage them to get vaccinated against COVID-19 for protection from potentially worse COVID-19-related outcomes.
