Consultative General Internal Medicine for Complex Care: The Model, Outcomes, and Lessons Learned

Area of Science:

• Internal Medicine
• Health Services Research

Background:

• Modern medicine faces increasing complexity, particularly with patients managing multiple chronic conditions.
• An aging population exacerbates the challenges in delivering optimal quality of care for complex medical problems.
• Existing healthcare delivery models struggle to meet the needs of patients with multifaceted health issues.

Purpose of the Study:

• To explore the role of consultative general internal medicine in addressing complex medical care.
• To highlight how these models can improve diagnostic accuracy and care coordination.
• To discuss the potential of destination-type practices in integrative, patient-centric care.

Main Methods:

• This is a narrative review synthesizing existing evaluations and models of consultative general internal medicine.
• The review examines the structure, expertise, and patient volume variations across institutions.
• It considers the impact of recent expansions in multidisciplinary care capabilities, such as during the COVID-19 pandemic.

Main Results:

• Consultative general internal medicine models synthesize evaluations, recommend testing and consultations, and integrate findings into cohesive care plans.
• Variability exists in expertise, patient volume, and structure among these practices.
• The COVID-19 pandemic has spurred opportunities for developing destination-type consultative practices.

Conclusions:

• Consultative medicine is crucial for integrative, patient-centric care.
• These models enhance diagnostic accuracy and coordinate multidisciplinary input effectively.
• Clear communication of actionable care plans to local care teams and patients is essential for successful implementation.
