Increasing Influenza and Pneumococcal Vaccination in the VA SCI&D Population

BACKGROUND/RATIONALE:
Research has found that persons with SCI who contracted influenza or pneumonia were 37 times more likely to die from influenza or pneumonia than comparable individuals from the general population. Pneumonia is often cited as the primary cause of death during chronic SCI. Prevention of influenza and pneumonia and their subsequent complications through immunization is key. Unfortunately, vaccination rates for veterans with SCI&D have been unacceptably low in the past (<27% in 1998), although more recently there is evidence to suggest that rates have improved somewhat.

OBJECTIVE(S):
The study objectives are to: 1) increase the proportion of veterans with SCI&D who receive influenza and pneumococal pneumonia vaccinations; 2) increase staff awareness of the importance of vaccination; 3) increase the proportion of SCI staff that are vaccinated to help protect themselves and their patients; and 4) to decrease respiratory complications resulting in outpatient clinic and inpatient hospital use.

METHODS:
A multiple strategy approach was implemented to target patients, providers and the VA health care system. System strategies include standing orders and computerized clinical reminders. Patients received personalized mailed reminders and educational materials. Practitioners received educational materials and reminders both to vaccinate and educate their patients as well as to receive an annual flu shot themselves. These interventions were made available to all 23 VA SCI Centers. The proportion of veterans with SCI&D vaccinated against influenza and pneumococcal pneumonia will be assessed using mailed patient surveys with telephone follow-up as well as medical chart reviews as part of the VA’s External Peer Review Program (EPRP). Respiratory-related morbidity and mortality will be determined using VA administrative databases. Self-report surveys will be used to assess rates of annual influenza vaccinations among contact staff at SCI Centers. The costs of the intervention compared to the savings from the reduction of vaccine-preventable diseases and their complications will be estimated using VA administrative data. Finally, acceptance of the system changes will be gauged by monitoring the 23 centers in a series of telephone assessments throughout the project.

FINDINGS/RESULTS:
There has been a steady increase in vaccination rates in veterans with SCI. In year 1, 62% of veterans with SCI received the influenza vaccine, while in year 2, this increased to 68%. Data from year 3 indicate that influenza vaccination rates are now 79%. Similarly for PPV, the rates were 60% in year 1 and 75% in year 2. Year 3 data indicate a PPV rate of 82%. Patient factors were significant predictors of vaccination including older age, non-smoker, prior inrluenza illness, having seen a VA provider in the past year, and rating vaccination as important. Year 4 influenza vaccination data were collected to assess the impact of the national vaccination shortage. Rates dropped slightly to 72% for influenza vaccination. This was much better than the general population.

IMPACT:
This interventions appear effective and sustainable. System changes have been implemented. These efforts should be sustained with minimial addition effort or cost.
