Plain English Summary

Background and study aims
Multiple diseases, medications and age-related changes put older adults at increased risk of harm from drugs. The majority of drug-related hospital visits are due to errors in prescribing and monitoring. Currently available text-based drug information resources can be lengthy for time-pressed clinicians and may not provide sufficient specific information regarding older adults. The researchers have developed concise, evidence-based, geriatric drug information resources (GPIDs) that use graphic design to facilitate learning. The aim of this study is to assess the efficiency and effectiveness of GPIDs. This is achieved by measuring the amount of time it will require prescribing clinicians to answer 5 case-based questions regarding prescribing for complex older adults using either GPIDs or usual drug information resources. Other aims include measuring knowledge retention using a knowledge-retention test, and assessing user-friendliness and overall reading experience of the GPIDs. The researchers will also investigate how various learning styles may impact the effectiveness and efficiency of the GPIDs.

Who can participate?
Prescribing clinicians (physicians, pharmacists, nurse practitioners) of any age currently practicing in Canada

What does the study involve?
The study involves randomly allocating prescribing clinicians (physicians, pharmacists and nurse practitioners) to one of two groups and instructing both to solve 5 identical case-based questions: one group is instructed to use only GPIDs and the other group is instructed to use their usual drug information resources. After this intervention, the researchers examine the required time for each group to answer the 5 questions. Next, both groups complete a series of questionnaires and tests in the following order: demographic questions, Health Professionals Inventory of Learning Styles (HPILS), knowledge retention test, open-ended questions about the GPIDs and finally questions about perceived user-friendliness and overall reading experience.

What are the possible benefits and risks of participating?
There are no risks or direct benefits related to participation in the study.

Where is the study run from?
The study is being run by the principle investigators based out of McMaster University and GeriMedRisk (Waterloo, Ontario) and takes place on the Surveymonkey platform.

When is the study starting and how long is it expected to run for?
October 2017 to July 2019

Who is funding the study?
Peer-reviewed grant from the Centre for Aging and Brain Health Innovation (CABHI)

Scientific titleAssessment of geriatric pharmacology information design: a randomized control trial
Study hypothesisIt is hypothesized that using geriatric pharmacology information design materials (GPIDs) will facilitate learning about prescribing medications to older adults. It is hypothesized that prescribing clinicians will find GPIDs to be a more user-friendly, efficient and effective format of learning about geriatric pharmacology compared to current, text-based formats.

Intervention typeOther
Primary outcome measureTime required by prescribing clinicians to complete 5 case-based questions about prescribing to older adults (start defined as time when online survey was accessed, stop defined as time when online survey completion button pressed; as measured by Survey Monkey). Measured at a single timepoint.
Secondary outcome measuresMeasured at a single timepoint:
1. Learning styles measured using the Health Professionals’ Inventory of Learning Styles (H-PILS)
2. Knowledge retention test scores (defined as the % of correct answers to the case-based short answer questions in part 2 of the survey)
3. User-friendliness of the infographics, assessed using a series of closed-ended questions about their reading experience followed by open-ended feedback questions
