Context The influenza virus and pneumococcal disease are a major source of morbidity and mortality in the United States each year. The annual influenza vaccination and the pneumococcal vaccine are the only way to currently reduce morbidity and mortality.

Objective The objective of this study is to document influenza vaccination levels for the 2003-2004 flu season and pneumococcal vaccination levels at the medical clinic of Dr. Edmundo Rosales, an internal medicine practice in Hillsboro, Oregon. This was to provide a basis by which to identify persons in need of vaccination and implement a plan to improve vaccination levels.. Information will be helpful in assessing current vaccination levels in comparison to CDC vaccination guidelines. The results will also be helpful in identifying limitations to optimal vaccination .

Design This study is to be a retrospective chart review. All charts of persons meeting CDC vaccination recommendation guidelines were reviewed from dates 09/01/03 - 03/31104 to encompass the 2003-2004 flu season. Additionally charts were reviewed for evidence of current pneumococcal vaccination.

Measured Outcomes Measured outcomes were documentation of vaccinations performed in office or documentation of vaccination received elsewhere reported by patients.

Results Vaccination rates of influenza for all identified patients measured 45.2%. For patients seen in the office during the 2003-2004 flu season 80.9% were vaccinated. The pneumococcal vaccine was documented in 50.3% of the population. Rates were also determined for each qualifying diagnosis, and for age groups.

Conclusion The office of Dr. Edmundo Rosales exceeds Healthy People 2010 vaccination goals of 60% for chronic conditions and 90% of patients over 65 for those patients seen in the office during the 2003~2004 flu season. A reminder system would improve the number of patients who visit the clinic for the annual flu vaccine. Pneumococcal vaccination rates fall short of the 60% goal. These rates can be improved with year-round vaccinations. IV
