Effectiveness of a pharmacist-physician collaborative program to manage influenza-like illness

This study was designed to examine the effectiveness of a collaborative agreement between physicians and community pharmacists to treat influenza-like illness (ILI). Every year in the US, there are at least 48,000 deaths and 226,000 hospitalizations resulting from influenza. Normally neuraminidase inhibitors are used to treat it by preventing the cleavage of virions from infected cells, therefore halting the spread of the virus within the body. However, this does not eradiate the virus. Studies found that early detection of the disease if critical to achieving optimal outcomes for treatment, but this is challenging. Many people use OTC products to alleviate symptoms instead of seeking immediate medical attention, delaying actual treatment of the infection. When patients come into the pharmacy to obtain OTC products, this is an opportunity for pharmacist intervention. A study conducted during the 2007-2008 and 2008-2009 flu seasons found that a pharmacist-physician collaborative program resulted in more immediate identification and treatment for patients with ILI. This study conducted from October 2013 to May 2014 and examined clinical outcomes and healthcare utilizations.

The study took place across fifty-five pharmacies in Michigan, Minnesota, and Nebraska. The pharmacists screened adult patients that came to pharmacies presenting symptoms of ILI. Then, they carried point-of-care rapid influenza diagnostic test (RIDT), completed a brief physical examination, and provided a corresponding treatment or referral through an established collaborative practice agreement (CPA) with a local licensed prescriber. After the encounter, pharmacists followed up 24 to 48 hours afterwards with the patient to assess their status and if any further intervention is needed. The outcomes measured were the number of patients screened, tested, and treated for ILI.

There were 121 patients screened overall. Of these patients, 75 were eligible for participation, and 8 had a positive RIDT and were managed accordingly. Of the tested patients 38.7% visited a pharmacist outside of normal office hours and 34.6% did not have a primary care physician. Just 3% said they felt worse at the follow-up. This study found that using a CPA enabled pharmacists to provide timely treatment to patients with and without influenza. One limitation of this study is that it did not use confirmatory testing of the RIDT results. Therefore, there was a possibility that patients were misclassified of having or not having influenza. This study demonstrated that the improved performance of CLIA-waved RIDTs and increased clinical training for pharmacists have made an opportunity for pharmacists and physicians to use a CPA to improve early detected and treatment for patients with influenza. Overall, a CPA could improve the number of patients visiting a physician for causes that only require management of symptoms. If more studies regarding this topic are conducted, hopefully this will lead to better management of patients presenting ILI.

  1. I think that this article sounds very interesting and I have never heard about a program like this before. Being able to prescribe medications and get patients the medical treatment they need could be so influential to the amount of flu deaths or hospitalizations per year. Since working in a pharmacy this flu season, I see how many parents, teens, or caregivers come into the pharmacy asking about what they can do to combat their early on-set of the flu. With pharmacists being able to care or get patients the medical attention patients need we could surely decrease the negative outcomes of the flu. Follow-ups would aid in getting the patients the total coverage they need.

  2. I think it is a great idea that pharmacist have the ability to prescribe medications especially for conditions like this. It is clearly very important to treat the flu when symptoms first start so that the patients condition does not worsen and require hospitalization or worse. I believe that community pharmacists are the most accessible health care professional as there are pharmacies located on almost ever corner. So if they were able to give people with the flu the medications they need to prevent further illness, I believe the flu would be much less prevalent. I also really like the idea of following up with the patients, this ensures a more comprehensive care. In addition, this takes the burden off of some other health care professionals who may not have the time to take care of additional patient due to the flu.
