Lawrence Leonard Weed (December 26, 1923 – June 3, 2017)[1] was an American physician, researcher, educator, entrepreneur, and author, who is best known for creating the problem-oriented medical record as well as one of the first electronic health records.
Dividing his time between research, patient care, and teaching, he developed a method that reorganized the structure of the medical record from being divided into the different sources for patient records (x-rays, prescriptions, physician notes) to one structured around a well-defined list of a patient's medical problems.
[10][11] He also helped develop PROMIS, a computerized medical information system based on the problem-oriented record, which used a touch screen;[12] introduced in 1969, that system was one of the earliest versions of an electronic medical record.
[2] He launched a company PKC, which developed methods for clinical information management systems.
[13] Weed was elected a member of the National Academy of Sciences in May 1972[14] and would later receive the Gustav O. Leinhard Award from the Institute of Medicine for his contribution of the problem-oriented medical record to the field of medicine.
