Abstract
BACKGROUND Seasonal influenza immunisation reduces cardiovascular events in high-risk patients, but 50% do not receive routine immunisation. The perceptions and current role of cardiologists in recommending and prescribing influenza immunisation has not been well described. METHODS We used an exploratory sequential mixed methods design. Semi-structured interviews of 10 cardiologists were performed to identify themes for quantitative evaluation. 63 cardiologists undertook quantitative evaluation in an online survey. The interviews and surveys addressed (a) attitudes and behaviours regarding influenza immunisation and (b) preventative care in cardiology. RESULTS One quarter (25.4%, n = 16) of cardiologists recommended influenza immunisation to all patients. Less than half (49.2%, n = 31) recommended influenza immunisation to secondary prevention patients. Almost 1/3 of respondents (31.7%, n = 20) were uncertain or unaware of the guidelines regarding influenza immunisation and patients with cardiac disease. Most cardiologists believed that general practitioners were responsible for ensuring patients received influenza immunisation (76.2%, n = 48). CONCLUSIONS Despite reducing cardiovascular events in high-risk patients, influenza immunisation is not widely recommended by cardiologists. Further clinician education is needed to address the knowledge gaps which prevent recommendation and uptake of this guideline directed treatment.

Plate A, Bagnoud C, Rosemann T, Senn O, Di Gangi S. Influenza vaccination uptake among at-risk patients in Switzerland-The potential of national claims data for surveillance. Influenza Other Respir Viruses 2023; 17:e13206. [PMID: 37840841 PMCID: PMC10570900 DOI: 10.1111/irv.13206] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 09/14/2023] [Accepted: 09/20/2023] [Indexed: 10/17/2023] Open
Abstract
Background Swiss national surveillance of influenza vaccination uptake rates (VURs) relies on self-reported vaccination status. The aim of this study was to determine VURs among at-risk patients, namely, patients ≥65 of age and adult patients with chronic diseases, using claims data, instead of self-reported measures, to investigate factors of vaccine uptake, and to assess different methodological approaches to conduct vaccination surveillance. Methods In this retrospective cross-sectional analysis, we determined VURs in three influenza seasons (2015/2016-2017/2018). Medication, diagnosis, or medical services claims were used as triggers to identify patients. For the calculation of VURs in patients with chronic diseases, we identified those by triggers in the given season only (Model 1) and in the given and previous seasons (Model 2). Regression analysis was used to identify factors associated with vaccination status. Results Data from 214,668 individual patients were analyzed. VURs over all seasons ranged from 18.4% to 19.8%. Most patients with chronic diseases were identified with the medication trigger, and we found no clinical significant differences in VURs comparing both models. Having a chronic disease, age, male gender, and regular health care provider visits were associated with increased odds of being vaccinated. Conclusions VURs were below the recommended thresholds, and our analysis highlighted the need for efforts to increase VURs. We assessed the identification of chronic diseases by medication claims and the calculation of VURs based on data of the given season only as an effective approach to conduct vaccination surveillance. Claims data-based surveillance may complete the national surveillance.

J Prim Care Community Health 2023; 14:21501319231214127. [PMID: 38041406 PMCID: PMC10693802 DOI: 10.1177/21501319231214127] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 10/20/2023] [Accepted: 10/27/2023] [Indexed: 12/03/2023] Open
Abstract
INTRODUCTION/OBJECTIVES Addressing vaccine hesitancy has become an increasingly important public health priority in recent years. There is a paucity of studies that have focused on vaccine hesitancy among older adults, who are known to be at greater risk of complications from infections such as COVID-19. We aim to explore the attitudes and beliefs of older adults regarding COVID-19 and influenza vaccines in Toronto, Ontario. METHODS Older adults enrolled in the Student Senior Isolation Prevention Partnership (SSIPP) program at the University of Toronto were contacted to participate in a phone survey and semi-structured interview. Survey data was analyzed descriptively, and attitude toward vaccination was compared between sociodemographic groups by using Fisher's exact test. Interview audio files were transcribed verbatim and analyzed inductively for themes and sub-themes. RESULTS All thirty-three (100%) older adults reported that they had received the first and second doses of the COVID-19 vaccine. Twenty-six (78.8%) participants reported intent to get vaccinated against influenza or had already received the influenza vaccine that year. Notably, only 2 out 7 (28.6%) individuals who did not plan to get vaccinated against influenza believed that vaccines offered by health providers are beneficial and only 3 out of 7 (42.9%) agreed that getting vaccines is a good way to protect oneself from disease. No other significant differences in attitudes among participants were found when compared by gender, ethnicity, or education level. The qualitative data analysis of interview transcripts identified 5 themes that impact vaccine decision making: safety, trust, mistrust, healthcare experience, and information dissemination and education. CONCLUSIONS Our data showed that older adults in the SSIPP program generally had positive views toward vaccination, especially toward the COVID-19 vaccines. However, several concerns regarding the effectiveness of the vaccines were brought up in interviews, such as the speed at which the vaccines were produced and the inconsistency in government messaging.
