At the different levels of the healthcare system, we see varying methods of healthcare used. These methods include managed care systems, case management, and primary healthcare.
Managed Care System:
The managed care system is designed to control the cost while maintaining the quality of care. The patient's care from admission to discharge is planned by the primary care provider or the case manager, also known as the gatekeeper. In a managed care system, the number of care providers is...

Area of Science:

  • Health Informatics
  • Digital Health
  • Bibliometrics

Background:

  • The COVID-19 pandemic underscored the significance of electronic health (eHealth).
  • Mapping eHealth research provides insights into its current status and future trajectory.
  • Data mining and visual analysis are key tools for understanding global research landscapes.

Purpose of the Study:

  • To systematically analyze global eHealth research trends from 2000-2021.
  • To identify key research areas, emerging topics, and collaboration patterns.
  • To provide a knowledge map of the eHealth research field.

Main Methods:
