Multimorbidity: conceptual basis, epidemiological models and measurement challenges.

Area of Science:

• Public Health
• Epidemiology
• Clinical Medicine

Background:

• The increasing prevalence of patients with complex chronic conditions necessitates a clear understanding of multimorbidity.
• Accurate measurement of multimorbidity is vital for effective clinical management, health systems, and epidemiological research.

Purpose of the Study:

• To review conceptual proposals for measuring multimorbidity.
• To identify epidemiological and methodological challenges in multimorbidity assessment.
• To bridge the gap between conceptual advancements and operational definitions.

Main Methods:

• Literature review of conceptual proposals and measurement strategies for multimorbidity.
• Discussion of classical comorbidity definitions and their evolution to multimorbidity.
• Analysis of conceptual models for operationalizing multimorbidity measurement.

Main Results:

• A significant discrepancy exists between the modern conceptualization of multimorbidity and current operational definitions.
• Measurement strategies have not evolved in parallel with theoretical advancements in understanding multimorbidity.
• Classical comorbidity concepts have evolved into a modern, multidimensional view of multimorbidity.

Conclusions:

• New methodological approaches are required to accurately measure multimorbidity.
• Improved measurement will provide better insights into the health impact on individuals.
• Addressing this gap is essential for advancing public health initiatives related to multimorbidity.
