MedPlus is the antidote to administrative headaches for the health care industry. Hospitals, clinics, and other health care organizations use the company's electronic health records (EHR) software to collect, store, and manage patient information. Its offerings include ChartMaxx, which pools a patient's clinical, financial, and administrative information into one Internet-accessible record, and the Web-based Care360 suite, which allows doctors to refill prescriptions, order lab tests, and send secure messages electronically. Its Care360 Data Exchange platform lets hospitals, physicians, and other parties share patient data. Formed in 1991, MedPlus is a subsidiary of clinical lab company Quest Diagnostics.
