Health care delivery is information intensive. As computer applications make information available to the decision maker with speed and accuracy, informatics applications will strengthen the infrastructure. This paper is the second part of a multicenter systems analysis study to design a common application software to support primary health care focused on information flow. We present the questionnaire analysis and observations from a field study of a district health site. Analyses using contingency tables revealed differences, some statistically significant. The field study confirmed that minor differences exist even within a district health site. Development of a common application software on the basis of information flow studies is feasible. However, to make optimum use of computer implementation, revision of the health information systems was recommended. It was suggested that application software be developed with the core data set required by the care providers to deliver and administrators to manage a vertical health program.
