Electronic Health Record (EHR) Study

Overview

Context

The use of EHRs are required; however, current EHR products are poorly designed in regards to support the information acquisition and decision making

Goal

To understand (cognitive) information requirements of primary-care team members

Questions

  1. What information requirements do primary care-team members need in performing patient-care work?

  2. How is the information used to form a decision?

Approach

Observations, interviews, qualitative data analysis (content analysis)

Outcome

A map of information requirements of primary-care team members

Next step: to design an EHR interface based on the information requirements (in another project)


Study design

In this study, we chose to use the method of Goal-Directed Task Analysis (GDTA; see more examples on Google Scholar), which is a special type of cognitive task analysis method. Main reasons include:

  • It overcomes the limitation of variation in workflow among different clinics

  • It provides a systematic way of analyzing data and documenting findings

  • It can transfer to interface design easily later on

 

Study process

For each clinic, we followed an iterative process of data collection & analysis:

  • We start studying each user by observing their daily work, focusing on their interaction with the computer system

  • Observation notes are reviewed and group discussions are held to come up with interview guide

  • Semi-structured interviews are performed with the user thereafter

  • After each interview session, we review the transcripts and briefly analyze the data to come up with follow-up questions for the next interview with this user

  • Each user is interviewed 1-3 times depending on their schedule

Next steps

Based on the information requirements generated in this study, we are working on designing an EHR interface based on the information requirements
