Summary
For systematic reviews in telemedicine, PubMed is the most effective database for retrieving relevant articles. It offers the highest accuracy and sensitivity for information retrieval in this field.
Area of Science:
- Health Informatics
- Medical Databases
- Telemedicine Research
Background:
- Systematic reviews require selecting the most effective databases for comprehensive literature searches.
- Identifying optimal databases is crucial for efficient information retrieval in specialized fields.
Purpose of the Study:
- To determine the most suitable database for information retrieval in the field of telemedicine.
- To compare the performance of major scientific databases for telemedicine literature searches.
Main Methods:
- Searched CINAHL, PubMed, Web of Science, and Scopus for telemedicine-related articles.
- Analyzed results using accuracy coefficient, sensitivity, uniqueness, and overlap metrics.
Main Results:
- PubMed demonstrated the highest suitability with 50.7% accuracy and 61.4% sensitivity for telemedicine topics.
- Article uniqueness varied, with PubMed yielding 38% unique results, while CINAHL had 3.0%.
- The highest overlap (18.6%) was between PubMed and Web of Science; less than 1% of articles were found in all databases.
Conclusions:
- PubMed is recommended as the primary database for telemedicine literature searches.
- Scopus and Web of Science can retrieve approximately 90% of relevant articles when used after PubMed.

An integrated healthcare system (IHS) is a set of organizations that provides for or arranges to provide coordinated and continuous service to a defined population. The IHS takes responsibility for that particular population's health status and outcome, both clinically and fiscally. An integrated healthcare system is a well-organized, well-coordinated, and collaborative network. The integrated delivery system is a network that connects different healthcare providers to deliver organized,...

The issues and trends in healthcare delivery are constantly changing. The COVID-19 pandemic is one recent issue that wreaked havoc on healthcare systems, causing a shortage of healthcare workers, high demand for medicines and supplies, and increased medical expenditure due to a lack of insurance. Other issues include rising healthcare costs and care fragmentation.

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...

Specialized care provided over an extended period is called tertiary care. Usually, a primary or secondary care physician will refer a patient to tertiary care. A patient's maximum physical and mental function is restored in tertiary care, which is caused due to the impact of a chronic illness or condition. Tertiary care aims to achieve the highest level of functioning possible while managing chronic illness. For example, a patient who falls and fractures their hip will need secondary care...
