Influenza immunizations in the elderly: a continuous quality improvement project

Area of Science:

• Geriatric Medicine
• Public Health
• Quality Improvement Science

Background:

• Continuous quality improvement is essential in healthcare settings.
• Influenza immunization is critical for elderly patient health.
• The Toronto Hospital's Department of Family & Community Medicine (TTH-DFCM) initiated a review of its influenza immunization program for seniors.

Purpose of the Study:

• To document the existing influenza immunization process for elderly patients.
• To quantify and compare influenza immunization rates across various patient and physician groups.
• To identify barriers and propose solutions to improve elderly immunization rates.

Main Methods:

• Evaluation Formative Research design.
• Utilized a computerized roster of 15,000 patients (age 65+) at TTH-DFCM.
• Analyzed immunization rates based on physician teams, physician status, patient gender, and age groups over two seasons (1996-1997).

Main Results:

• Overall immunization rates increased from 75.4% to 78.7% between 1996 and 1997.
• Significant improvements were observed in the Blue physician team, patients aged 70-74, and female patients.
• Data provided a basis for comparison with other healthcare centers.

Conclusions:

• The study successfully demonstrated improved influenza immunization rates in the elderly over a two-year period.
• Identified specific areas and patient subgroups benefiting from quality improvement efforts.
• The study design serves as a model for future clinical quality improvement projects in immunization programs.
