The association between health information technology and influenza vaccine uptake among adults with heart disease.

Assess the association of health information technology (HIT) on influenza vaccine (IV) uptake among adults with heart disease. The association of four different uses of HIT - (1) look up health information, (2) schedule medical appointments, (3) refill prescriptions online and (4) communicate with healthcare providers on IV uptake - was analyzed using multiple logistic regression. Adults with heart disease who use the internet to look up information (adjusted odds ratio [AOR] = 1.48, 95% CI: 1.39-1.59; p < 0.001), fill up prescription (AOR = 1.87, 95% CI: 1.69-2.06; p < 0.001), and communicate with a healthcare provider (AOR = 1.95, 95% CI: 1.23-3.10; p = 0.005) had a higher uptake of IV unlike those who did not. Using the internet in patient-healthcare system engagement via HIT was associated with increase IV uptake. Future studies should assess the impact of population-level variables on this relationship.
