ABSTRACT This study sought: to describe influenza vaccination coverages among COPD patients treated in a primary-care setting; and to analyse the factors linked to compliance with vaccination recommendations. This was a descriptive study in a primary-care (PC) setting. Each of the 2422 randomly selected medical practitioners included in the study was required to recruit five COPD patients. Information was drawn from patients' clinical histories and personal interviews. As the dependent variable, we took the answer (yes or no) to the question, "did you have an influenza vaccination in the most recent campaign?"; and as independent variables, we analysed socio-demographic data, health-status related variables, lifestyles and history of pneumococcal vaccination. A total of 10,711 patients were enrolled 87.2% reported having been vaccinated in the most recent campaign. In conclusion, Spanish COPD patients treated in a primary-care setting can be said to enjoy good vaccine coverages against the influenza virus. More frequent contact with the general practitioner and a history of pneumococcal vaccination increase the likelihood of being vaccinated considerably, and measures should be implemented with the aim of improving coverages among younger subjects and those who lead less healthy lifestyles.

    ABSTRACT: Patients who suffer from chronic obstructive pulmonary disease (COPD) often experience acute exacerbations, which frequently require hospitalization and lead to increased mortality. The most common causes of exacerbation are viruses, bacteria, and air pollutants. The risk of influenza and pneumococcal-related hospitalization and death has been shown to be high among COPD sufferers of all ages.Influenza vaccination has shown itself to be effective in reducing morbidity and mortality in patients with underlying chronic respiratory diseases. Pneumococcal vaccine is effective in reducing the incidence of invasive disease. Therefore, COPD sufferers are a target group to be vaccinated against influenza and pneumococcus.Several coverage studies have identified non-compliant subjects and factors associated with influenza and pneumococcal vaccination recommendations. Age-based strategies have proved better than vaccinating high-risk-specific groups. Joint administration of influenza and pneumococcal vaccination has shown beneficial additive effects. Notwithstanding, implementation of some other strategies are needed to improve coverage.

    ABSTRACT: Older adults, who often have more than one chronic disease, are at greater risk of influenza and its complications. However, because they often see physicians for other more pressing complaints, their physicians, focusing on one condition, may forget to suggest preventive measures for other diseases such as influenza. This study investigates what major factors affect an older adult with more than one chronic condition missing a vaccination opportunity. Retrospectively reviewing a nationally representative random sample of medical claims from Taiwan's National Health Insurance Research Database during the period 2004 - 2006, we first identified patients sixty-five years or older who had visited physicians. Each patient was assigned a proxy for health status, the Charlson Comorbidity Index (CCI) score. An older claimant was defined has having "absence of a vaccination" when he or she had visited a physician during an influenza season but did not receive an influenza vaccination. Multivariate logistic regression was performed to estimate how likely it would be for older adults with various CCI scores to miss a vaccination. Out of 200,000 randomly selected claims, 20,923 older adults were included in our final analysis. We found older adults with higher CCIs to be more likely to have an absence of vaccination (p < 0.01). Our multivariate logistic regression results revealed CCI to be the greatest predictor of absence of vaccination, after controlling for individual factors and medical setting. Older adults with CCI scores three or higher were nearly five times more likely to miss a vaccination than those with a CCI of zero [OR: 4.93 (95%CI, 4.47-5.42)]. Those with CCIs of one and two were 2.53 and 3.92 times more likely to miss vaccination than those with a CCI of zero [OR 2.53 (95%CI, 2.26-2.84) and OR 3.92 (95%CI, 3.51-4.38), respectively]. The greater the number of certain comorbid conditions, the greater the likelihood a flu vaccination will be missed. Physicians would be well advised to not let the presenting problems of older patients distract from other possible health problems that might also need attention, in this case influenza vaccinations.

    ABSTRACT: BACKGROUND: Three main categories of persons are targeted by the French influenza vaccination strategy: all persons aged 65 years or over, those aged less than 65 years with certain underlying medical conditions and health care workers. The main objective of this study was to estimate rates of influenza immunization in these target groups attending a medical consultation for two consecutive influenza seasons: 2009--2010 (seasonal and pandemic vaccines) and 2010--2011 (seasonal vaccine). METHODS: A standardized questionnaire was mailed to 1323 general practitioners (GPs) of the Sentinelles Network, collecting data on all patients seen on a randomly assigned day. For every patient, following information was collected: age, gender, BMI, presence of any medical condition that increases risk of severe influenza illness, and vaccination status for the three vaccines mentioned. RESULTS: Two hundred and three GPs agreed to participate and included 4248 patients. Overall, in persons with high risk of severe influenza, the estimated vaccine coverages (VC) were 60%, (95% CI = 57%; 62%) for the seasonal vaccine in 2010--2011, 61% (59%; 63%) for the seasonal vaccine in 2009--2010 and 23% (21%; 25%), for the pandemic vaccine in 2009--2010. Among people aged 65 years and over (N=1259, 30%) VC was estimated for seasonal vaccines at 72% (70%; 75%) in 2010--2011 and 73% (71%; 76%) in 2009--2010, and 24% (22%; 26%) for the pandemic vaccine. The lowest seasonal VC were observed in younger persons (<65 years) with underlying medical conditions, in particular pregnant women (<10%) and overweight persons (<30%). CONCLUSIONS: Our study shows that influenza vaccination coverage among patients of the French Sentinelles general practitioners remains largely below the target of 75% defined by the 2004 French Public Health Law, and underscores the need for the implementation of public health interventions likely to increase vaccination uptake.
