BACKGROUND: Hypertension (HTN) has become a major public health problem which can cause
serious complications when it is not well-controlled. Prevention and effective care of HTN require
a population-based registry. Thus, establishing this registry can be used to collect comprehensive,
timely, and reliable data on epidemiology cases. The aim is to create a registry for the collection of
highly required prospective data that will present an in-depth analysis of the characteristics of all
individuals with HTN and track them over a particular chronological interval.
MATERIALS AND METHODS: The study was divided into three phases: At first, a comprehensive
literature review was conducted to determine the proposed data classes and data fields. Then, the
final minimum data set was designed by a two-round Delphi consensus approach of 20 experts of
cardiologists, nephrologists, nutritionist, and health information management. Finally, a web-based
registry system was developed by a Structured Query Language environment.
RESULTS: A total of two clinical and nonclinical data categories with nine data classes and 68 data
fields were selected for their inclusion in the registry following the consensus phase. A web-based
registry was designed with a modular and layered architecture.
CONCLUSIONS: This study provides an appropriate information infrastructure for active tracing and
monitoring of individuals with HTN. It has provided a practical information system allowing quality
improvement, aggregate reporting for planning, and research purposes.
