2. Clinical Workflow Integration: Outline how telemedicine services will be integrated into existing clinical workflows and healthcare systems.
3. Regulatory and Legal Considerations: Address the regulatory and legal issues associated with telemedicine, including licensure, reimbursement, and privacy.
4. Patient and Provider Training: Develop a training program for both patients and healthcare providers to ensure effective use of telemedicine services.
5. Evaluation and Continuous Improvement: Establish metrics and methods for evaluating the effectiveness of the telemedicine program and for making continuous improvements.
