Should Patients With COPD Be Vaccinated?

Abstract

BACKGROUND: Exacerbations of COPD are a major component of the socioeconomic burden related to COPD, and frequent exacerbations are associated with greater decline in health status. Tracheobronchial infections are involved in 50 -70% of exacerbations, so influenza and pneumococcal vaccines are recommended for prevention. The aim of this study was to determine the level of knowledge among COPD patients about the vaccines, find the rate of patients inoculated with both influenza and pneumococcal vaccines, and assess the effectiveness of vaccination status. METHODS: Patients with COPD were recruited from the out-patient clinic of our hospital between September and October 2012. Subject demographic data such as age, gender, level of education, and smoking status were recorded. Vaccination status, number of subjects who were informed by a health-care professional about immunization, and COPD-related emergency or hospital admissions triggered by tracheobronchial infections over 1 y after administration of both influenza and pneumococcal vaccines were noted. RESULTS: Eighty-eight subjects were enrolled during the study period. Eighty-two subjects were male (93.2%), 6 subjects were female (6.8%), and the median age was 61.5 y. According to Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2006 classification, 5 subjects were in stage 1 (5.7%), 22 subjects were in stage 2 (25%), 34 subjects were in stage 3 (38.6%), and 27 subjects were in stage 4 (30.7%). Sixty-two subjects had graduated from primary school (70.5%), 21 subjects had graduated from high school (23.9%), one subject had graduated from university (1.1%), and 4 subjects had no education (4.5%). Forty-five subjects (51%) were vaccinated. There was no significant correlation between level of education and vaccination status (P ‫؍‬ .37). Both COPD-related emergency department and hospital visits were significantly decreased in vaccinated patients with COPD (P < .001 and P ‫؍‬ .02, respectively). Of all the subjects, 39.7% (35 of 88 subjects) mentioned that no health-care professional recommended vaccination. CONCLUSIONS: Physicians should be more aware of vaccination and recommend both influenza and pneumococcal vaccines to all patients with COPD to reduce exacerbations.

Factors Affecting Influenza Vaccination Rates among Patients with Chronic Obstructive Pulmonary Disease in Rize, Turkey

“…On the contrary, another study concluded that receiving vaccination was not related to the level of education but that the advice of health care professionals (particularly a doctor) led to high vaccination compliance [16]. Our findings showed that there was no relationship be- tween the level of education and status for vaccination.…”

Better knowledge and regular vaccination practices correlate well with higher seasonal influenza vaccine uptake in people at risk: Promising survey results from a university outpatient clinic

“…Other studies also point out that the advice of a health care professional (particularly a physician) leads to better vaccination compliance. 11,21,22 A recent population-based study from Germany showed that vaccination uptake is independently associated with perceived severity of influenza, perceived vaccination effectiveness, and perceived likelihood or severity of vaccination side effects, 9 whereas a study from Canada reported that knowledge plays a smaller role in the vaccination decision-making process than beliefs concerning risk perception and vaccination effectiveness. 23 Our study demonstrates that as knowledge increases, vaccination rates increase.…”

Influenza and Pneumonia Vaccination Rates and Factors Affecting Vaccination among Patients with Chronic Obstructive Pulmonary Disease

“…Several studies performed on an elderly population (>65 years) in Turkey indicated that the minimal influenza vaccination rate in patients with COPD was 5.9% and the maximal rate was 27.3% (6). In another single-centre study, pneumococcal and influenza vaccination rates were 51% (7). …”
