Population aging raises concerns regarding the increases in the rates of morbidity and mortality that result from influenza and its complications. Although vaccination is the most important tool for preventing influenza, vaccination program among high-risk groups has not reached its predetermined aims in several settings. This study aimed to evaluate the impacts of clinical and demographic factors on vaccine compliance among the elderly in a setting that includes a well-established annual national influenza vaccination campaign.
This cross-sectional study included 134 elderly patients who were regularly followed in an academic medical institution and who were evaluated for their influenza vaccination uptake within the last five years; in addition, the demographic and clinical characteristics and the reasons for compliance or noncompliance with the vaccination program were investigated.
In total, 67.1% of the participants received the seasonal influenza vaccine in 2009. Within this vaccination-compliant group, the most common reason for vaccine uptake was the annual nationwide campaign (52.2%; 95% CI: 41.4-62.9%); compared to the noncompliant group, a higher percentage of compliant patients had been advised by their physician to take the vaccine (58.9% vs. 34.1%; p<0.01).
The education of patients and health care professionals along with the implementation of immunization campaigns should be evaluated and considered by health authorities as essential for increasing the success rate of influenza vaccination compliance among the elderly.
人口老龄化引起了人们对流感及其并发症导致发病率和死亡率上升的关注。虽然疫苗接种是预防流感的最重要手段,但在一些情况下,高风险人群的疫苗接种计划并未达到预定目标。本研究旨在评估临床和人口统计学因素对既定年度国家流感疫苗接种活动背景下老年人疫苗接种依从性的影响。
这是一项横断面研究,纳入了在一所学术医疗机构中定期接受随访的 134 名老年人患者,评估他们在过去五年内接种流感疫苗的情况;此外,还调查了人口统计学和临床特征以及疫苗接种计划依从或不依从的原因。
在这项研究中,2009 年共有 67.1%的参与者接种了季节性流感疫苗。在这个接种疫苗的人群中,接种疫苗的最常见原因是全国范围内的年度疫苗接种活动(52.2%;95%CI:41.4-62.9%);与不依从组相比,更高比例的依从组患者是经医生建议接种疫苗(58.9% vs. 34.1%;p<0.01)。
应当对患者和卫生保健专业人员进行教育,并由卫生当局实施免疫接种活动,这被认为是提高老年人流感疫苗接种依从率的关键因素。
