Use of information technology in medication reconciliation: a scoping review

To identify studies involving information technology (IT) in medication reconciliation (MedRec) and determine how IT is used to facilitate the MedRec process.

The search strategy included a database search of MEDLINE and Cumulative Index of Nursing and Allied Health Literature (CINAHL), hand-searching of collected material, and references from articles retrieved. The database search was limited to English-language papers. MEDLINE includes publications dating back to 1950 and CINAHL includes those dating back to 1982. The search included articles in both databases up to March 2009. Boolean queries were constructed using combinations of search terms for medication reconciliation, IT, and electronic records.

Three inclusion criteria were used. The study had to (1) involve the MedRec process, (2) be a primary study, and (3) involve the use of IT. Selection was performed by 2 reviewers through consensus. Data related to study characteristics, focus, and IT use were extracted.

The included studies described a range of IT used throughout the MedRec process, from basic email and databases to specialized MedRec tools. A generic MedRec workflow was created and types of IT found in the studies were mapped to the workflow activities as well as to a set of functionalities based on the Institute of Medicine's Key Capabilities of an Electronic Health Record System. In the studies reviewed, IT was mainly used to obtain medication information. Although there were only a few MedRec tools in the studies, those that did exist supported the central activities for MedRec: comparison of medications and clarification of discrepancies.

MedRec is an important process to ensure patient medication safety. Evidence was found that IT can and has been used to facilitate some MedRec activities and new applications are being developed to support the entire MedRec process.
