A comparison of electronic records to
paper records in mental health centers

Abstract
Objective. Medication documentation is a critical aspect of quality patient care. The current study examined whether
electronic medical records provide medication documentation that is more complete and faster to retrieve than traditional
paper records.
Method. This study involves a comparison of archived paper medical records to recent electronic medical records through
chart review. A convenient sample of three large community mental health centers in Indiana was used. Medical charts for
180 patients with schizophrenia were rated on a checklist composed of 16 items that was adapted from a national project.
Documentation that existed before implementation of the electronic medical record system was compared with that after
implementation at each of the three centers. The main outcome measures were completeness and retrieval time of medication
documentation.
Results. Electronic medical records provided medication documentation that was more complete and faster to retrieve than
paper records across all centers and within each center. On average, electronic medical records were 40% more complete and
20% faster to retrieve.

                                                                                                                                                                  Downloaded from by guest on September 7, 2015
Conclusion. Electronic records have potential to improve medication management for patients in mental health centers over
traditional records. However, medication documentation for patients diagnosed with schizophrenia was found to be deficient
in many areas, regardless of documentation format.
