Camps, A NonTraditional Medical
Setting
•  Over 12,000 camps operate in
America, looking after
11,000,000 people each year
(American Camping
Association, 2012)
•  Camps have been historically
slow to adopt new technologies
even though the camping
industry services such a large
number of people
•  One medical technology that is
starting to gain traction in the
camping industry is electronic
medical records
Unstructured Interview
Analysis Approach
•  The overall purpose of this initial interview was to elicit the goals & purpose of CampDoc from the developers, how the tools work,
any known usability issues, and any other information about the system they felt would be pertinent to the usability analysis
•  A large portion of our knowledge about the CampDoc website was gained from this initial unstructured interview
Patient Portal Heuristic Evaluation
Heuristic Evaluation
•  Two analysts referenced a set of 11 heuristics adapted from two
previous sets developed by Nielson & Molich (2009) for text based
websites and Zhang, Johnson, Patel, Paige, & Kubose (2003) for
medical devices
•  The analysts identified a number of positive usability elements while
conducting their heuristic evaluation and over 35 potential system
errors in total

Modified Applied Cognitive Task Analysis (ACTA)
•  Two subject matter experts (SMEs) were interviewed for the modified
ACTA using a typical scenario
•  A task diagram was constructed for the task of accessing traditional paper
patient records in a camp setting based on the initial simulation interview

CampDoc
Key Findings
•  CampDoc is an electronic health records
system specifically designed for camps
and other small organizations
•  The CampDoc website can be accessed
from either a Patient Portal or a Provider
Portal
•  Input data should be saved automatically
•  The primary users of the system are
parents and non-medical camp personnel,
so the system language should be tailored
to a more general audience.
