Better Patient Experience is Associated with Better Vaccine Uptake in Older Adults: Multicentered Cross-sectional Study

Determinants of pneumococcal vaccination among older adults: A scoping review

OBJECTIVES

To identify the range of factors that impact health behaviours pertaining to the uptake of pneumococcal vaccination (PV) among older persons.

STUDY DESIGN

Scoping review.

METHODS

This review followed Arksey and O'Malley's framework. Five databases: PubMed, CINAHL, PsycINFO, Scopus and Embase were searched for relevant studies on PV uptake among outpatient older adults ≥65 years published between January 2013 and October 2023. Data were extracted and verified using a standardised template, and synthesised using inductive content analysis. Findings were classified according to Andersen's behavioural model of health services use (BMHSU).

RESULTS

Twenty-seven papers were included in the final analysis. Reception of PV was influenced by predisposing factors such as (i) awareness and risk perception, (ii) demographic characteristics, and (iii) cultural beliefs towards preventive medicine; enabling factors including (i) disease and vaccine literacy, (ii) past experience with preventive health services, and (iii) access to relevant resources; as well as reinforcing factors namely, (i) vaccine efficacy and safety, (ii) social influence, (iii) support from healthcare professionals, and (iv) vaccine administration environment.

CONCLUSIONS

Older adults' health behaviours, particularly their attitudes towards vaccination are often complex and this attests to the need for multidimensional, cross-sector barrier-specific strategies to raise PV coverage. Key issues identified in this review highlight the focus areas that healthcare providers, policy makers and other stakeholders should collaborate on to resolve underutilisation of preventive medicine and promote health among this population.

Family Medicine Implementation to Maternal and Child Health in Rural Japan: A Narrative Review

This research provides a critical narrative review of maternal and child health (MCH) in rural Japan, reflecting broader challenges faced by aging societies globally. The study explores the intertwined roles of professional and lay care in sustaining rural communities, emphasizing the unique position of family medicine and primary care in enhancing MCH services. The scarcity of healthcare resources, particularly the shortage of obstetricians and the weakening of traditional community support systems, underscores the challenges in these areas. Our review method involved a comprehensive search of PubMed for articles published from April 2000 to August 2024, focusing on MCH issues in rural Japan. This study highlights several critical gaps in rural MCH provision: the migration of medical professionals to urban centers, the transformation of social structures affecting traditional caregiving, and the lack of specialized MCH training among primary care physicians. We discuss potential solutions such as incentivizing obstetric care in rural areas, integrating MCH education within family medicine curricula, and revitalizing community-based support systems. By addressing these issues, the research aims to formulate actionable strategies to bolster MCH services, thus ensuring better health outcomes and sustainability of rural communities in Japan and similar settings worldwide.

Immunogenicity and safety of influenza vaccine in patients with lung cancer receiving immune checkpoint inhibitors: A single-center prospective cohort study

INTRODUCTION

Patients with lung cancer have a high risk of influenza complications. International guidelines recommend annual influenza vaccination for patients with cancer. Immune checkpoint inhibitors (ICIs) are progressively used to treat lung cancer. Data regarding immunogenicity and safety of influenza vaccine are limited in patients with lung cancer receiving ICIs; therefore, we conducted this single-center, prospective observational study in the Japanese population.

METHODS

Patients with lung cancer receiving ICIs and influenza immunization were enrolled. Blood samples were collected from patients for serum antibody titer measurement pre- and 4 ± 1 weeks post-vaccination. The primary endpoint was seroprotection rate (sP) at 4 ± 1 weeks post-vaccination. The secondary endpoints were geometric mean titer (GMT), mean fold rise, seroresponse rate (sR), seroconversion rate (sC), and immune-related adverse events (irAEs), defined as adverse effects caused by ICI administration, 6 months post-vaccination.

RESULTS

Influenza vaccination in the 23 patients included in the immunogenicity analyses significantly increased GMT for all strains, and sP, sR, and sC were 52%-91%, 26%-39%, and 26%-35%, respectively. In the 24 patients included in the safety analyses, 7 (29%) and 5 (21%) patients exhibited systemic and local reactions, respectively. Only one patient (4%) (hypothyroidism, grade 2) showed post-vaccination irAEs.

CONCLUSIONS

Overall, influenza vaccination in patients with lung cancer receiving ICIs showed acceptable immunogenicity and safety, thus supporting annual influenza vaccination in this population.

The relationship between having a usual source of primary care and COVID-19 parental vaccine hesitancy: A nationwide survey among Japanese mothers

Background

Studies have shown that a usual source of care increases the receipt of child preventive care; however, the relationship between having a usual source of primary care and COVID-19 parental vaccine hesitancy has not been fully investigated. The aims of this study were to elucidate the characteristics of mothers with a primary care physician, and to explore the relationship between having a usual source of primary care and COVID-19 parental vaccine hesitancy among mothers in Japan.

Method

This cross-sectional survey-based study included 4516 mothers. Using a chi-square test, the characteristics of mothers with and without a primary care physician were compared. Poisson regression was applied to evaluate the relationship between having a usual source of primary care and parental COVID-19 vaccine hesitancy.

Results

Mothers with a usual source of primary care had higher education, lower mental distress, had younger children, and were less hesitant toward the child's COVID-19 vaccination. Vaccine hesitancy was observed in 39.8% of mothers with a usual source of primary care and 45.5% of those without. Poisson regression analysis showed that mothers with a primary care physician were less vaccine-hesitant (IRR = 0.90, 95% CI = 0.84-0.96) after adjusting for potential confounders.

Conclusion

This study suggested that having a usual source of primary care may contribute to lower parental COVID-19 vaccine hesitancy. However, the high vaccine hesitancy rate, even among mothers with a usual source of primary care, warrants healthcare providers to be equipped to help parents make informed decisions about vaccination through the continuity of care.

Impact of COVID-19 Outbreak on Influenza and Pneumococcal Vaccination Uptake: A Multi-Center Retrospective Study

During the coronavirus disease 2019 (COVID-19) pandemic, global vaccination efforts declined due to the burden on health systems and community resistance to epidemic control measures. Influenza and pneumococcal vaccines have been recommended for vulnerable populations to prevent severe pneumonia. We investigated community response towards influenza and pneumococcal vaccines (pneumococcal conjugate vaccine and pneumococcal polysaccharide vaccine) after the COVID-19 outbreak in Taiwan. We retrospectively included adults who visited Chang Gung Memorial Hospital (CGMH) institutions for influenza or pneumococcal vaccination from January 2018 to December 2021. The first case of COVID-19 in Taiwan was detected in January 2020; therefore, in this study, hospitalized cases from January 2018 to December 2019 were defined as "before COVID-19 outbreak," and hospitalized cases from January 2020 to December 2021 were defined as "after COVID-19 outbreak". A total of 105,386 adults were enrolled in the study. An increase in influenza vaccination (n = 33,139 vs. n = 62,634) and pneumococcal vaccination (n = 3035 vs. n = 4260) were observed after the COVID-19 outbreak. In addition, there was an increased willingness to receive both influenza and pneumococcal vaccinations among women, adults without underlying disease and younger adults. The COVID-19 pandemic may have increased awareness of the importance of vaccination in Taiwan.

Views and Perceptions of People Aged 55+ on the Vaccination Programme for Older Adults in the UK: A Qualitative Study

Vaccination reduces the risks related to infectious disease, especially among more vulnerable groups, such as older adults. The vaccines available to older adults in the UK through the government-funded programme currently include influenza, pneumococcal, shingles and COVID-19 vaccines. The purpose of the programme is disease prevention and improving wellbeing among the ageing population. Yet, the target population's views of the programme remain unknown. This paper aims to increase the understanding of older adults' perceptions of the vaccination programme available in the UK. A total of 13 online focus groups (56 informants) were carried out for this qualitative study. The findings indicate that getting vaccinated involves personal decision-making processes, which are influenced by previous experiences and interpersonal interactions. Factors related to the wider community and culture are less prominent in explaining vaccination decisions. However, opportunistic vaccination offers, a lack of information and a lack of opportunities to discuss vaccines, especially with healthcare professionals, are prominent factors. The study provides in-depth data about the rationale behind older adults' vaccination decisions in the UK. We recommend that the provision of information and opportunities to discuss vaccines and infectious disease be improved to enable older adults' to make better informed decisions regarding the vaccines available to them.

Modified MRC assessment and FEV1.0 can predict frequent acute exacerbation of COPD: An observational prospective cohort study at a single-center in Japan

INTRODUCTION

Acute exacerbation (AE) of chronic obstructive pulmonary disease (COPD) is a fatal event, leading to poor outcomes among COPD patients. However, exact frequency and poor prognostic factors are not well known in Japan.

METHODS

and patients, To assess the frequency and risk factors of AE, we performed this prospective cohort study at the Kameda Medical Center in Japan between during 2011 and 2013. AE was defined as an acute worsening of respiratory symptoms according to the GOLD guideline. Furthermore, we compared the exacerbation-free time between the groups.

RESULTS

A total of 330 patients (230 COPD patients and 100 smoking controls) were enrolled in the study. The mean age in the study was 73 years, and 94% of the patients were male. As for the frequency of AE, 0.17 times/patients/year was found in all patients. The frequency of AE increased as the COPD disease severity (p = 0.042 by Jonch-Heere terpla test). GOLD I patients had longer exacerbation-free time than GOLD II, and GOLD II grade COPD patients had longer exacerbation-free time than GOLD III grade COPD patients. In terms of risk factors for AE, logistic regression analysis showed that Modified Medical Research Council (mMRC) scale ≥3 and FEV_1.0% <50% were independent poor prognostic factors for moderate grade of AE events, and mMRC scale ≥3 was independent poor prognostic factor for severe AE events.

CONCLUSION

The frequency of AE increases as the disease severity becomes more severe. We found mMRC scale >3 and FEV1 <50% were risk factors for AE-COPD.

How Do Users Respond to Mass Vaccination Centers? A Cross-Sectional Study Using Natural Language Processing on Online Reviews to Explore User Experience and Satisfaction with COVID-19 Vaccination Centers

To reach large groups of vaccine recipients, several high-income countries introduced mass vaccination centers for COVID-19. Understanding user experiences of these novel structures can help optimize their design and increase patient satisfaction and vaccine uptake. This study drew on user online reviews of vaccination centers to assess user experience and identify its key determinants over time, by sentiment, and by interaction. Machine learning methods were used to analyze Google reviews of six COVID-19 mass vaccination centers in Berlin from December 2020 to December 2021. 3647 user online reviews were included in the analysis. Of these, 89% (3261/3647) were positive according to user rating (four to five of five stars). A total of 85% (2740/3647) of all reviews contained text. Topic modeling of the reviews containing text identified five optimally latent topics, and keyword extraction identified 47 salient keywords. The most important themes were organization, friendliness/responsiveness, and patient flow/wait time. Key interactions for users of vaccination centers included waiting, scheduling, transit, and the vaccination itself. Keywords connected to scheduling and efficiency, such as "appointment" and "wait", were most prominent in negative reviews. Over time, the average rating score decreased from 4.7 to 4.1, and waiting and duration became more salient keywords. Overall, mass vaccination centers appear to be positively perceived, yet users became more critical over the one-year period of the pandemic vaccination campaign observed. The study shows that online reviews can provide real-time insights into newly set-up infrastructures, and policymakers should consider their use to monitor the population's response over time.

Association Between Varicella-Zoster Virus Vaccination and Patient Experience in Elderly Japanese Outpatients: A Case-Control Study

BACKGROUND

This study examined the association between patient experience (PX, events experienced by patients during primary care that are an indicator of patient-centered quality) of primary care and varicella-zoster virus (VZV) vaccine uptake in older adults.

METHODS

A case-control study of VZV vaccination was conducted at a community hospital in Ibaraki, Japan. Patients aged 65 years or older who had continuously been patients of the hospital between April 2018 and April 2021 were included in the study. The vaccinated group consisted of 166 VZV-vaccinated patients. The controls consisted of 29 age- and sex-matched patients who did not receive VZV vaccination. A self-administered questionnaire was distributed between August and September 2021. It included the Japanese version of the Primary Care Assessment Tool Short Form (JPCAT-SF) to evaluate PX and included questions about recommendations for VZV vaccination by a physician and the vaccination history of relatives. Multivariable and intermediate factor analyses were used to assess whether there was an association between VZV vaccination and PX.

RESULTS

Questionnaires were sent to 457 subjects. Responses from 228 (116 in the vaccination group and 112 in the non-vaccinated group) were included in the analysis. Multivariable analysis, which excluded physician recommendation for VZV vaccination as a variable because it was an intermediate factor in the analysis, showed an association between PX and VZV vaccination (odds ratio, 1.38; 95% confidence interval, 1.00-1.92; P = .049).

CONCLUSIONS

PX was associated with past VZV vaccination. Physician recommendation for VZV vaccination was an intermediate factor between PX and VZV vaccination.

Development and validation of a Japanese version of the person-centered primary care measure

Background

Although primary care (PC) is an indispensable part of the health system, measuring its quality is challenging. A recent measure of PC, Person-Centered Primary Care Measure (PCPCM), covers 11 important domains of PC and has been translated into 28 languages. This study aimed to develop a Japanese version of the PCPCM and assess its reliability and validity.

Methods

We employed a cross-sectional mail survey to examine the reliability and content, structure, criterion-related, and convergent validity of the Japanese version of the PCPCM. This study targeted 1000 potential participants aged 20–74 years, selected by simple random sampling in an urban area in Japan. We examined internal consistency, confirmatory factor analysis, correlation between the Japanese version of the Primary Care Assessment Tool-Short Form (JPCAT-SF), and the association between the PCPCM score and influenza vaccine uptake.

Results

A total of 417 individuals responded to the survey (response rate = 41.7%), and we used the data of 244 participants who had the usual source of care to assess the reliability and validity of the PCPCM. Confirmatory factor analysis demonstrated sufficient structural validity of the original one-factor structure. The overall Cronbach’s alpha was 0.94. The Spearman correlation coefficient between PCPCM and JPCAT-SF was 0.60. Influenza vaccine uptake was not significantly associated with total PCPCM score.

Conclusions

The study showed that the Japanese version of the PCPCM has sufficient internal consistency reliability and structural- and criterion-related validity. The measure can be used to compare the quality of primary care in Japan and other countries.

Patient experience (PX) among individuals with disabilities in Japan: a mixed-methods study

Background

People with disabilities (PWDs) tend to be disadvantaged in terms of receiving preventive medicine and medical checkups. About 7.6% of the Japanese population is estimated to have a disability. Although patient experience (PX) is an effective measure of patient-centeredness, little is known about the PX of PWDs. The present study aimed to compare the PX of PWDs with those of the non-disabled both quantitatively and qualitatively.

Methods

The present study involved a questionnaire survey and a free-response question on the survey form. The quantitative part of the study involved a comparison of JPCAT scores between PWDs and non-disabled participants. JPCAT is composed of five primary care principles: First contact, Longitudinality, Coordination, Comprehensiveness (service provided and service available), and Community orientation. Descriptive statistics were used to assess age, sex, years of education, self-rated health status, and type of disability (for PWDs). Multivariable analysis was performed using a linear regression model to detect differences between PWDs and non-disabled participants in total and domain-specific JPCAT scores. The model included the following confounding variables: age, sex, years of education, and self-rated health status. The qualitative part of the study involved a thematic analysis of answers to the free-response question.

Results

Data from 338 participants (169 PWDs and 169 non-disabled participants) were analyzed (response rate of 36% for PWDs). After adjusting for age, sex, years of education, and self-rated health status, PWD scores were significantly lower than those of non-disabled participants for the Longitudinality, Community Orientation, and Comprehensiveness (services available) domains of the JPCAT. Qualitative analysis yielded six themes, each of which was further divided to have Disability-Specific and General themes.

Conclusions

JPCAT scores in PWDs were significantly lower than those of non-disabled participants for the Longitudinality, Community Orientation, and Comprehensiveness (services available) domains. Qualitative analysis revealed that PWDs shared several themes with non-disabled participants, but also to face unique challenges due to disabilities, such as the lack of a health care provider familiar with disabilities and the insurance transition at age 65, a unique feature of the Japanese health care system.

Trial registration

The study was a non-interventional, observational research trial, and thus registration was not required.

Patient experience of residents with restricted primary care access during the COVID-19 pandemic

OBJECTIVES

To evaluate primary care access for COVID-19 consultation among residents who have a usual source of care (USC) and to examine their associations with patient experience during the pandemic in Japan.

DESIGN

Nationwide cross-sectional study.

SETTING

Japanese general adult population.

PARTICIPANTS

1004 adult residents who have a USC.

MAIN OUTCOME MEASURES

Patient experience assessed by the Japanese version of Primary Care Assessment Tool Short Form (JPCAT-SF).

RESULTS

A total of 198 (19.7%) reported restricted primary care access for COVID-19 consultation despite having a USC. After adjustment for possible confounders, restricted primary care access for COVID-19 consultation was negatively associated with the JPCAT-SF total score (adjusted mean difference = -8.61, 95% CI -11.11 to -6.10). In addition, restricted primary care access was significantly associated with a decrease in all JPCAT-SF domain scores.

CONCLUSIONS

Approximately one-fifth of adult residents who had a USC reported restricted primary care access for COVID-19 consultation during the pandemic in Japan. Our study also found that restricted primary care access for COVID-19 consultation was negatively associated with a wide range of patient experience including first contact. Material, financial and educational support to primary care facilities, the spread of telemedicine and the application of a patient registration system might be necessary to improve access to primary care during a pandemic.

Usual source of primary care and preventive care measures in the COVID-19 pandemic: a nationwide cross-sectional study in Japan

OBJECTIVES

To assess multiple preventive care measures and to examine their associations with having a usual source of primary care and primary care performance during the COVID-19 pandemic in Japan.

DESIGN

Nationwide cross-sectional study.

SETTING

Japanese general adult population.

PARTICIPANTS

1757 adult residents.

PRIMARY OUTCOME MEASURES

Fourteen preventive care measures aggregated the overall screening, immunisation and counselling composites.

RESULTS

Depression screening, zoster vaccination and tetanus vaccination had low implementation rates even among participants with a usual source of primary care. After adjustment for possible confounders, having a usual source of primary care was positively associated with all preventive care composites. Primary care performance assessed by the Japanese version of Primary Care Assessment Tool Short Form was also dose dependently associated with an increase in all composites. Results of the sensitivity analyses using a different calculation of preventive care composite were similar to those of the primary analyses.

CONCLUSIONS

Receipt of primary care, particularly high-quality primary care, contributed to increased preventive care utilisation even during the COVID-19 pandemic. However, the rate of mental health screening in primary care was at a very low level. Therefore, addressing mental health issues should be a major challenge for primary care providers during and after the pandemic.

Knowledge, attitudes, beliefs and barriers of healthcare professionals and adults ≥ 65 years about vaccine-preventable diseases in Spain: the ADult Vaccination drIverS and barriErs (ADVISE) study

Since 2018, Spanish National Immunization Guidelines include vaccination recommendations for adults ≥65 years. To determine whether health-care professionals and the ≥65 years target group value the need for these recommendations, a cross-sectional study was conducted to capture and describe their knowledge, attitudes, beliefs and behaviors about vaccination. Online surveys were administered to representative groups of general practitioners (GPs), primary care nurses and adults ≥65 years from six major cities (and surrounding rural areas) in Spain. Main topics were attitudes and awareness of vaccines, perceptions about vaccination in adults ≥65 years, and impact of the COVID-19 pandemic on vaccination uptake. A total of 286 health-care professionals (185 GPs, 101 nurses) and 400 adults aged ≥65 years participated in the survey. GP and nurse groups agreed strongly about the importance of influenza and pneumococcal vaccination in the target population. Longer patient visit times were identified as a key factor toward promoting vaccination. The ≥65 years sample group, especially those ≥75+ years and/or with chronic diseases, was reasonably positive about the effectiveness and benefits of vaccines. Lower vaccination rates for the pneumococcal than influenza vaccine (29% vs. 80%) in the ≥65 years sample group suggest that efforts are needed to improve pneumococcal vaccine uptake. Aligning with other published works, GPs have a key role in promoting vaccination in the target population. The COVID-19 pandemic appears to have heightened awareness about the importance of vaccination among health-care professionals and adults ≥65 years.
