Abstract

Purpose: To compare the level of knowledge in vaccination against influenza and pneumococcus of patients with chronic obstructive pulmonary disease (COPD) who are managed in an Integrated Care Program (ICP) with those who receive usual care (UC).

Methods: A telephone survey of patients diagnosed with COPD registered in public care networks or private institutions was done. A descriptive and comparative analysis of the characteristics of the ICP and UC groups was carried out. The relationship between belonging to an ICP and the level of knowledge about vaccination was evaluated using Propensity Score Matching (PSM) and multivariate logistic and ordinal regression models.

Results: Of 674 study participants, 27.2% were from the ICP group. ICP patients were older, more frequently men, from a higher socioeconomic stratum and a higher educational level (p<0.05). 75.5% of the patients in the ICP group had a high level of vaccination knowledge compared to 42.7% in the UC group (p<0.001). In the multivariate analysis, adjusting for sociodemographic variables, years of COPD diagnosis, and comorbidities, belonging to the ICP was associated with a higher probability of answering questions about vaccination correctly and having a high level of knowledge (OR 3.397, IC 95% 2.058-5.608, p<0.001).

Conclusion: Patients with COPD managed in an ICP have a higher level of knowledge in vaccination against influenza and pneumococcus, compared to patients in usual care.
