“…Lastly, the predominate outcome variable in most of these studies was inpatient hospitalization 6,7,10–12 ; outpatient and physician service costs usually were ignored. One prominent study, by Gilman et al, 9 examined the cost-effectiveness of influenza vaccination with a nationally representative sample of Medicare beneficiaries over multiple influenza seasons (1999–2003), using survey- and claim-based measures to determine vaccination status and outcomes, including inpatient and physician services associated with acute and chronic respiratory conditions.…”

Background Influenza accounts for a large proportion of hospitalizations and deaths among older adults, resulting in substantial health care expenses. Influenza vaccinations are effective in reducing respiratory infections in younger populations, but it is less certain whether they reduce costs associated with respiratory infections among older adults. Objective The purpose of this study was to determine whether influenza vaccination of older adult Medicare beneficiaries reduced costs associated with acute and chronic respiratory conditions during 3 recent influenza seasons. Methods This study analyzed the relationship between influenza vaccination and costs for respiratory conditions among Medicare beneficiaries ≥55 years of age in influenza seasons (October–May) between 2002 and 2005 using data from the Medicare Current Beneficiary Survey. Two-part multiple regressions of vaccination status were estimated on the probability and cost of treating respiratory conditions in each influenza season controlling for influenza risk factors and other covariates. Various sensitivity tests were conducted by type of service, subgroup analysis for specific population risk segments, propensity score-matched comparisons, and difference equations. Results The study sample included 13,402 Medicare beneficiaries for the 3 influenza seasons examined. Vaccination rates varied between 67.3% and 74.9% over the 3 influenza seasons. In unadjusted comparisons, no significant difference in the cost of treating respiratory conditions was found between vaccinated and unvaccinated beneficiaries in 2002/2003 (−$104), but vaccinated beneficiaries had significantly higher mean cost differentials in the more recent influenza seasons ($258 in 2003/2004, P = 0.012; $254 in 2004/2005, P = 0.003). Based on 2-part multiple regressions of vaccine status over the 3 seasons combined, costs of respiratory conditions were $142 dollars higher on average for vaccinated beneficiaries (P = 0.014). The base regression models showed no significant cost savings from vaccination in any year. Results of 2 of the 54 sensitivity tests that were conducted indicated significant savings from vaccination (inpatient costs for 2002/2003 and difference in total costs for persons unvaccinated in 2002/2003 but vaccinated in 2003/2004). Conclusion In this study of older adults, no significant cost savings were found with influenza vaccines in the 3 influenza seasons examined (2002–2005) when the outcome was measured in terms of differential spending for acute and chronic respiratory conditions.

“…Accordingly, the annual influenza vaccination represents an important health behavior in the workplace as it provides the best possible prevention of influenza onset and its complications (CDC, 2010a;Gilman, Bonito, & Eicheldinger, 2007; WHO, 2011). However, vaccination rates are lower than desired (CDC, 2010b;Robert-Koch-Institut, 2008).…”

Workplace health promotion aims at maintaining and promoting employees health and well-being which is fundamental for organizational and societal functioning and success. In Chapter 2, it was explored whether health climate, i.e., employees' shared perceptions of organizational health-related efforts, operates as a job resource, supporting employees' affective commitment to the organization. This would underline the importance of workplace health promotion. In this thesis, the focus was on behavioral workplace health promotion and seasonal influenza vaccination behavior in particular. Successful health behavior promotion requires effective and evidence-based health interventions. This premises a profound understanding of underlying motivational and volitional factors and their interplay.Cross-sectional analyses in Chapter 3 investigated whether intention formation by outcome expectancies depended on individuals' past behavior. Analyses in Chapter 4 built on these findings, examining motivational processes longitudinally with regard to subsequent vaccination behavior. Along with, the putative moderating influence of individuals' past behavior on intention formation and future behavior was investigated.In Chapter 5, the prediction of vaccination behavior was analyzed with structural equation modeling, comparing a model derived from the health action process approach to a model adjusted to behavior specifics. The aim was to identify the most suitable composition of social-cognitive variables for behavior prediction.In Chapter 6, health messages promoting vaccination behavior were compared in a randomized trial, along with compensatory health beliefs (CHB). The role of CHB, considered a self-defense strategy, within the intention-behavior relation was examined. Of particular interest was, whether CHB would interfere with health messages.In Chapter 7, theoretical and practical implications of the findings are discussed.

Im Sinne des "job demands-resources model" (vgl., Bakker & Demerouti, 2007; Llorens, Bakker, Schaufeli, & Salanova, 2006) In der vorliegenden Arbeit liegt der Fokus auf der Verhaltensprävention, bei der das individuelle (Gesundheits-)Verhalten im Zentrum der Präventionsarbeit steht (Vgl., Ulich & Wülser, 2009). Unter Gesundheitsverhalten werden hierbei alle Aktivitäten verstanden, die der Vorbeugung von Krankheiten, sowie ihrer rechtzeitigen Entdeckung, dienen und das Ziel verfolgen, Gesundheit und Wohlbefinden zu fördern (Connor, 2001). Dazu zählen bspw.körperliche Aktivität oder eine gesunde Ernährung (Schwarzer, 2008).In Kapitel 3-6 wird die Teilnahme an der saisonalen Influenzaimpfung als Gesundheitsverhaltensweise diskutiert. Die zum Teil umfangreichen und dichten Arbeitsbedingungen in einem Betrieb können zu einem erhöhten Infektionsrisiko für Influenza führen. Daher wird die Grippeschutzimpfung als beste präventive Maßnahme empfohlen (CDC, 2010a;Robert-Koch...
