Intervention Components (click on component to see a list of all articles that use that intervention): Patient Reminder/Invitation,
Intervention Description: The intervention involved sending reminders to patients via the health care system's electronic health record patient portal. Patients due for an influenza vaccine were sent a letter via the patient portal reminding them about the importance of influenza vaccination, the safety of the vaccine, and the morbidity associated with influenza. Patients were randomized within primary care practices to one of four study groups: no reminder, one reminder, two reminders, or three reminders ,[object Object],. The content of the portal reminder letter was grounded in the Health Belief Model and principles of health literacy. The secure notification was sent by email or text, based on the patients' standard portal preference, informing them that "a message from your doctor" had been posted on the portal. It's important to note that influenza vaccination was not mentioned in the title of the message, and patients had to log in to the portal to read the letter ,[object Object],.

Intervention Results: The primary outcome of the study was the receipt of one or more influenza vaccinations as documented in the electronic health record. The study found that the influenza vaccination rates were 37.5% for those receiving no reminders, 38.0% for those receiving one reminder (P = .008 vs no reminder), 38.2% for those receiving two reminders (P = .03 vs no reminder), and 38.2% for those receiving three reminders (P = .02 vs no reminder) ,[object Object],. The study also assessed five secondary outcomes related to receipt of one or more influenza vaccinations in the relevant season. These outcomes included vaccinations in predetermined subgroups (age, sex, race/ethnicity, insurance, and influenza vaccination in prior 2 years), vaccinations that were self-reported by patients or proxies via the portal in response to portal reminders, influenza vaccinations before December 15, 2018, vaccinations among those who opened one or more portal reminders vs those who did not open the reminders, and vaccinations in patients in the upper half vs bottom half of overall portal use ,[object Object],. Overall, the study found that generic patient portal reminders may be slightly effective in increasing influenza vaccination rates, but more intensive or more targeted patient motivational strategies appear to be needed ,[object Object],.
Conclusion: Generic patient portal reminders were effective in minimally increasing influenza vaccination rates, but more intensive or more targeted patient motivational strategies appear to be needed.
Study Design: The study utilized a randomized controlled trial (RCT) design to evaluate the effect of patient reminders sent via the health care system's electronic health record patient portal on influenza vaccination rates ,[object Object],. The RCT design is a robust method for assessing the impact of interventions, as it allows for the comparison of outcomes between different intervention arms and a control group.

Setting: The setting for the information provided in the PDF file is related to a study conducted in a health system, focusing on patient reminder and recall systems for improving immunization rates ,[object Object],. The study involved a total of 164,205 patients who were randomly allocated to one of the four study arms ,[object Object],. If you need further details about the specific setting or context of the study, please feel free to ask!
Population of Focus: The target audience for the study mentioned in the PDF file is the population of patients within the UCLA (University of California, Los Angeles) health care system. Specifically, the study involved 164,205 patients in 52 primary care practices who had used the patient portal within 12 months ,[object Object],. The study aimed to evaluate the effect of patient reminders sent via the health care system's electronic health record patient portal on influenza vaccination rates within this population. If you need more specific details about the target audience or any other aspect of the study, please let me know!
Sample Size: The study involved a total of 164,205 patients who were randomly allocated to one of the four study arms ,[object Object],. This large sample size allowed for a robust evaluation of the effect of patient reminders sent via the health care system's electronic health record patient portal on influenza vaccination rates. If you have further questions about the sample size or any other aspect of the study, feel free to ask!
Age Range: The study included patients who were at least 6 months of age at the start of the intervention, making them eligible for influenza vaccination ,[object Object],. Therefore, the age range of the patients included in the study spans from at least 6 months and older. If you have any more questions or need further details, feel free to ask!
