RESUMO
BACKGROUND: Adult immunizations prevent morbidity and mortality yet coverage remains suboptimal, in part due to missed opportunities. Clinical decision support systems (CDSSs) can improve immunization rates when integrated into routine work flow, implemented wherever care is delivered, and used by staff who can act on the recommendation. METHODS: An adult immunization improvement project was undertaken in a large integrated, safety-net health care system. A CDSS was developed to query patient records and identify patients eligible for pneumococcal, influenza, or tetanus immunization and then generate a statement that recommends immunization or indicates a previous refusal. A new agency policy authorized medical assistants and nurses in clinics, and nurses in the hospital, to use the CDSS as a standing order. Immunization delivery work flow was standardized, and staff received feedback on immunization rates. RESULTS: The CDSS identified more patients than a typical paper standing order and can be easily modified to incorporate changes in vaccine indications. The intervention led to a 10% improvement in immunization rates in adults 65 years of age or older and in younger adults with diabetes or chronic obstructive pulmonary disease. Overall, the improvements were sustained beyond the project period. The CDSS was expanded to encompass additional vaccines. CONCLUSIONS: Interdepartmental collaboration was critical to identify needs, challenges, and solutions. Implementing the standing order policy in clinics and the hospital usually allowed immunizations to be taken out of the hands of clinicians. As an on-demand tool, CDSS must be used at each patient encounter to avoid missed opportunities. Staff retraining accompanied by ongoing assessment of immunization rates, work flow, and missed opportunities to immunize patients are critical to sustain and enhance improvements.

The goal of this effort was to improve adult immunization rates within a large urban health care system. To measure improvement efforts, we calculated each month the percentage of adults 65 years and older who leave clinic visits with up-to-date pneumococcal vaccination were calculated. This was accomplished through the development of three key aspects: standing orders, an immunization registry, and an algorithm to recommend vaccinations based on age and past vaccination history, but also on health history and risk factors for specific diseases.

BACKGROUND: In some settings, immunization rates for ethnic minorities are less than those of non-Hispanic white populations. This study examines demographic differences in the rate of pneumococcal and influenza immunization in an ethnically diverse older patient population seeking care at an urban primary care clinic system. METHODS: The setting is an integrated system of 11 federally qualified community health centers serving approximately 100,000 unduplicated patients annually. We linked data from chart audits performed in 2001-2003 for quality assurance purposes with patient registration data to evaluate vaccination rates in 740 patients age 66 years and older who had at least 3 primary care visits in the previous 2 years. RESULTS: Factors significantly associated with receipt of pneumococcal vaccination in multivariable analysis were Hispanic ethnicity (odds ratio [OR] 1.66-1.77, P = 0.01), medical comorbidities (OR 1.48, P = 0.03), psychiatric comorbidities (OR 2.0, P = 0.001), use of a family medicine versus internal medicine clinic (OR 2.3, P < 0.001), and age (OR 1.04 for 1 year increase, P = 0.004). Factors significantly associated with influenza vaccination were having insurance (OR 2.25, P = 0.014), medical comorbidities (OR 1.71, P = 0.036), age (OR 1.03 for 1 year increase, P = 0.045), later year of audit (OR 1.68-1.73, P = 0.015), and a greater number of clinic visits (OR 1.69, P = 0.006). CONCLUSIONS: Among older regular users of our public community health centers, minority populations have equal or higher immunization rates compared with non-Hispanic whites.
