Abstract:

A longitudinal electronic medical record (EMR) allows physicians to access laboratory results in the context of the patient's medical history. Daily lab order volumes were tracked for physicians with access to an EMR and physicians with no EMR access to assess whether physicians with EMR access changed their lab order habits significantly more than a matched set of controls. This study shows that physicians will change their ordering habits in order to access the lab results in the context of an EMR.

Longitudinal Studies

Longitudinal studies are also widely used in other medical and social science fields. For instance, in cardiovascular research, they can monitor patients' health over decades to identify risk factors for heart disease, such as high cholesterol or smoking, and evaluate the long-term effectiveness of preventive measures. Similarly, in mental health studies, researchers might follow individuals from adolescence into adulthood to understand the development and progression of conditions like...
