Summary
Background: Alcohol use is a significant part of a patient’s history, but details about consumption
are not always documented. Electronic Health Record (EHR) systems have the potential
to improve assessment of alcohol use and misuse; however, a challenge is that critical
information may be documented primarily in free-text rather than in a structured and
standardized format, thereby limiting its use.
Objective: To characterize the use and contents of free-text documentation for alcohol use in
the social history module of an EHR.
Methods: This study involved a retrospective analysis of 500 alcohol use entries that include
structured fields as well as a free-text comment field. Two coding schemes were developed
and used to analyze these entries for: (1) quantifying the reasons for using free-text
comments and (2) categorizing information in the free-text into separate elements.
In addition, for entries indicating possible alcohol misuse, a preliminary review
of other structured parts of the EHR was conducted to determine if this was also documented
elsewhere.
Results: The top three reasons for using free-text were limited ability to describe alcohol
use frequency (75%), amount (22%), and status (18%) with available structured fields.
Within the free-text, descriptions of frequency were most common (79%) using words
or phrases conveying occasional (61%), daily (13%), or weekly (12%) use. Of the 36
cases suggesting alcohol misuse, 44% had mention of alcohol problems in the problem
list or past medical history.
Conclusions: Based on the early findings, implications for improving the structured collection
and use of alcohol use information in the EHR are provided in four areas: (1) system
enhancements, (2) user training, (3) decision support, and (4) standards. Next steps
include examining how alcohol use is documented in other parts of the EHR (e.g., clinical
notes) and how documentation practices vary based on patient, provider, and clinic
characteristics.
