Electronic Health Records (EHR) HIMA 4160 Fall 2009
What is an Electronic Health Record? Before we answer that, what is a patient record? • commonly referred to as the patient's chart or medical record • amalgam of all the data acquired and created during a patient's course through the heath care system HIMA 4160 Fall 2009
Purpose of a Patient Record "to recall observations, to inform others, to instruct students, to gain knowledge, to monitor performance, and to justify interventions" Reiser, S. (1991). The Clinical Record in Medicine. Part 1: Learning from Cases. Annals of Internal Medicine, 114(10): 902-907 HIMA 4160 Fall 2009
Purpose of Patient Records • create the basis for the historical data • support communication among providers • anticipate future health problems • record standard preventive measures • identify deviation from expected trends • provide a legal record • support clinical research and public health HIMA 4160 Fall 2009
Weakness of the Paper Record System • Pragmatic and Logistical issues. • Can I find the data I need when I need them? • Can I find the medical record in which they are recorded? • Can I find the data within the record • Can I find what I need quickly? • Can I read and interpret the data once I find them? • Can I update the data reliably with new observations in a form consistent with the requirements for future access by me or other people? • Redundancy and Inefficiency • Influence on Clinical Research HIMA 4160 Fall 2009
