HYPERTENSION STUDY PROGRAM SUMMARY

The Hypertension Study program consists of a collection of compatible
routines designed to acquire and interpret information related to the
decision procedures used in a specific strategy of treatment of hyper-
tension.

Acquisition of information by the program occurs through the medium
of a CRT which displays a sequence of queries posed by a questionnaire
driver.  Answers to the questions are processed by the program logic
which accordingly decides what further questions are to be asked.
Information which is acquired is stored in disc files, accessible to
all modules of the program.

Different phases of the questionnaire are administered by separate
program modules.  Certain phases are intended to be answered by para-
medical personnel (e.g., the phase calling for input of laboratory
findings), while other phases may be answered directly by the patient.
The latter phases are programed to permit the simplest data input and
to provide easy correction (under the assumption that the questionnaire
will often be taken by persons unskilled in the use of data-processing
procedures).

Program modules related to data input deal with:

0   Preliminary medical history

0   Physical findings

0   Laboratory findings

9   Medication history

0  Response to treatment.regi,yn

Program modules related to recommended therapy propose:
