Kenneth J. Smith, MD, MS, is a Professor of Medicine and Clinical and Translational Science and a core faculty member of the Center for Research on Health Care at the University of Pittsburgh. His research centers on the cost-effectiveness of common medical interventions, most notably on pneumococcal, influenza, and varicella vaccination and on the impact of racial disparities in vaccination rates. He has published in many other areas, including pelvic inflammatory disease, influenza management strategies, diabetes prevention and treatment, VA formulary decisions, anticoagulation and thrombotic disorder management, and hospital-physician communication. In addition, Dr. Smith is Deputy Editor of the Journal Medical Decision Making.

A Markov model compared influenza likelihood in older adults with (1) status quo vaccination (August-May) to maximize vaccine uptake or (2) vaccination compressed to October-May (to decrease waning vaccine effectiveness impact). Results suggest that compressed vaccination could decrease waning vaccine effectiveness and decrease influenza cases in older adults.

The 4 Pillars Practice Transformation Program is an economically reasonable intervention to improve vaccination rates in adults <65-years-old, and could have a substantial public health impact.

Using recently observed low live attenuated influenza vaccine (LAIV) effectiveness values, fewer influenza cases will occur if LAIV is not used compared with having LAIV as a vaccine option. However, having the option to use LAIV may be favored if LAIV effectiveness returns to prior levels or if the absence of vaccine choice substantially decreases overall vaccine uptake.

To estimate the cost-effectiveness of an intervention to increase pneumococcal, influenza, and pertussis-containing vaccine uptake in adults aged 65 and older in primary care practices, we used a Markov decision analysis model, comparing the cost-effectiveness of the 4 Pillars Practice Transformation Program with no intervention.
