Factors influencing seasonal influenza vaccination behaviour among elderly people: a systematic review

Abstract

This is the first systematic review to analyse the factors influencing influenza vaccination behaviour of elderly people using a framework integrating the HBM and the TRA. The framework identified key factors of influenza vaccination and presented the inter-relation of behaviour-related variables. However, further well-designed studies are required to explore the inter-relationships accurately and comprehensively.

Determinants of vaccination uptake, and influenza vaccine effectiveness in preventing deaths and hospital admissions in the elderly population; Treviso, Italy, 2014/2015-2016/2017 seasons

“…This is in line with a recent systematic review on factors influencing flu vaccination behavior, which include previous vaccination history as one of the key factors, together with age, poor health status, medical service use, receiving knowledge/information from healthcare professionals. 32 Regarding the effectiveness on reducing the risk of death (any cause) and the risk of influenza-related hospitalization, we found that, adjusting simultaneously for other individual characteristics, influenza vaccination was significantly associated with lower mortality and influenza-related hospitalization rates, and the benefit was found for all the discharge diagnoses including, influenza, pneumonia, respiratory, and cardiovascular diseases. Moreover, repeated influenza vaccination in the previous seasons influenced positively the vaccine effectiveness in the elderly.…”

The role of health determinants in the influenza vaccination uptake among older adults (65+): a scope review

“…Additional factors in uencing in uenza vaccination uptake by older citizens found in this analysis range from in uence of family/friend [22,26,32,42] to household arrangements/children [10,18,19,21,22,28,30,31,33,37,38,42,47,48], previous vaccinations [9, 15, 17-20, 22, 29, 30, 32, 35, 38, 42, 51] and other health parameter [9, 15-21, 25, 27, 28, 31, 35, 39]. This implies that the psychosocial environment, like in children, impacts VU.…”

“…The study designs are divided into 34 cross-sectional studies of which 13 studies were developed by means of a secondary analysis of already existing data [11, 12, 14, 15, 19-21, 28-30, 38, 39, 41] and two cross-sectional studies following a qualitative study design [26,32], four randomized controlled trials [43][44][45][46], two systematic reviews [47,48], two cohort studies [49,50] and two theoretical reviews [51,52].…”

“…Methods used to evaluate vaccination uptake in the cross-sectional and cohort studies and in the systematic reviews were: questionnaires and surveys [13-15, 19, 21, 22, 25, 28, 34-36]; telephone interviews [20,23,27,29,30,33,39,41]; data retrieved from national/regional authorities and health care institutions [12,38,40,49,50]; data retrieved from medical records or vaccination registries [9,10,31,37]; combined methods [11,17,18,24]; focus group discussions [26,32]; face-to-face interviews [42]; database search [47,48].…”

“…The number of participants older than 65 years of study samples ranges from 11% to 100% of all initially included study participants (n= 19.604.711) from across the globe in countries from four continents and in following care settings: Community-dwelling or non-institutionalized citizens [9, 15, 21, 23, 27-31, 33, 36, 39, 42, 48, 50], nursing homes [12,38], combined settings [32,37], outpatient clinics [44], hospitals [18,22], primary care centres/clinics or practices [24,26,43,45], home-based primary care settings [10] and data bases such as the Medicare registry, national vaccine industry or settings of health services/insurance authorities [13,40,46]. In 12 studies, details about the care setting of the participants were not indicated [11,14,16,17,19,20,25,34,35,41,47,49].…”
