Abstract

BACKGROUND

Elderly patients benefit from influenza vaccination, but the number of Japanese elderly patients who are vaccinated is insufficient. Several factors are associated with influenza vaccination acceptance, but little is known about Japanese elderly outpatients. The purpose of this study was to examine factors associated with influenza vaccination in elderly outpatients in Japan.

METHODS

During the 2017-2018 influenza season, outpatients from one hospital and one clinic in Kitaibaraki City, Ibaraki, Japan, participated in this study. Patients answered a self-report questionnaire exploring factors such as their vaccination status during the 2017-2018 season, past influenza vaccination, perceived susceptibility to influenza and adverse events of the vaccine, perceived vaccine efficacy, physician recommendations. Multivariable logistic regression analyses were conducted to identify factors associated with vaccination.

RESULTS

Of 377 patients, 316 (83.8%) responded, and the vaccination rate was 57%. Eighty-three patients (27.0%) reported that their physician recommended the influenza vaccine. In multivariate analysis, influenza vaccination was associated with higher age (odds ratio (OR) 1.09, 95% confidence interval (CI) 1.03-1.14), physician recommendations (OR 2.49, 95% CI 1.18-5.25), low perceived susceptibility to vaccine-related adverse events (OR 0.33, 95% CI 0.15-0.74), and belief in vaccine efficacy (OR 4.73, 95% CI 2.08-10.8).

CONCLUSIONS

Influenza vaccination was associated with belief in vaccine efficacy, perceived susceptibility to vaccine-related adverse events, physician recommendations, and older age. Increasing the frequency of physician recommendations may lead to increased vaccination coverage.

摘要

背景

老年患者可从流感疫苗接种中获益，但日本接种流感疫苗的老年患者数量不足。有几个因素与流感疫苗接种的接受度相关，但对于日本老年门诊患者的情况却知之甚少。本研究的目的是调查日本老年门诊患者中与流感疫苗接种相关的因素。

方法

在2017 - 2018年流感季节期间，来自日本茨城县北条崎市一家医院和一家诊所的门诊患者参与了本研究。患者回答了一份自我报告问卷，该问卷探讨了诸如他们在2017 - 2018季节的疫苗接种状况、过去的流感疫苗接种情况、对流感和疫苗不良事件的感知易感性、感知疫苗效力、医生建议等因素。进行多变量逻辑回归分析以确定与疫苗接种相关的因素。

结果

377名患者中，316名（83.8%）做出了回应，疫苗接种率为57%。83名患者（27.0%）报告称他们的医生推荐了流感疫苗。在多变量分析中，流感疫苗接种与较高年龄（比值比（OR）1.09，95%置信区间（CI）1.03 - 1.14）、医生建议（OR 2.49，95% CI 1.18 - 5.25）、对疫苗相关不良事件的低感知易感性（OR 0.33，95% CI 0.15 - 0.74）以及对疫苗效力的信念（OR 4.73，95% CI 2.08 - 10.8）相关。
