Study: Pharmacist intervention improves shingles vaccine rate

COLUMBUS, Ohio - A new study from researchers at Ohio State University is reporting that older patients who receive written information on shingles were almost three times more likely to get vaccinated than those that didn’t receive a similar communication. The study is also one of the first to show that using a patient’s electronic medical record coupled with pharmacist intervention markedly improves preventative care of shingles over the current standard.

While people over the age of 60 account for more than half of all shingles cases, less than 15% get the vaccination that helps prevent the blistering skin rash, which can cause lingering nerve pain, researchers noted. 

The research team, led by Stuart Beatty, a pharmacist with Ohio State’s College of Pharmacy, says that the low vaccination rate is due to a combination of factors including lack of awareness, cost, access to clinics able to store the fragile vaccine and the fact that face-to-face appointments don’t offer enough time to discuss shingles, also known as herpes zoster.

“With older patients, there are usually more pressing health issues to discuss during routine appointments, so herpes zoster falls off the list,” Beatty said. “Plus, as a live vaccine, it’s not appropriate for people with certain illnesses. There usually isn’t time to figure all that out in a regular office visit.”

Neeraj Tayal, an Ohio State Wexner Medical Center general internist on the research team, noted that while the numbers of patients vaccinated may seem small, the study was conducted from 2010 to 2011, a time when the national vaccination average was actually 6%, far lower than today’s average of 15%. Tayal also suggested that despite the overall low vaccination rate, the results challenge the notion that there are too many logistical barriers to this type of effort.

“It took pharmacists a matter of minutes to review the chart and mail out a prescription. This saved the physician time, the patient time, and improved the overall health of our patients,” Tayal said. “By utilizing pharmacists as members of a care team, many perceived logistical barriers were managed and overcome.”

For the six-month study, which was supported by the Ohio State Center for Clinical and Translational Science, Beatty and his team used electronic medical record data to identify more than 2,500 patients over the age of 60 without a documented herpes zoster vaccination. Some were randomized to receive information about shingles via a secure email linked to their online personal health record or a mailed postcard, while others received no information outside what they may have gotten in a routine doctor visit. 

Pharmacists reviewed the EMRs of patients who had received emails or mailed information to identify eligible vaccine candidates, and then sent them a vaccination prescription via standard mail, along with a list of local pharmacies that offered the vaccine. Vaccine fulfillment was tracked by reports submitted to the team by local pharmacists.

Patients with an active PHR that received email information on shingles had the highest vaccination rate of 13.2% compared to a rate of 5% for patients with an active PHR that did not receive the email information. For patients that did not have an active PHR but did receive mailed information, the vaccination rate was 5.2% compared to a rate of 1.8% for patients without an active PHR and received no information.

The study was published in The American Journal of Medicine.
