Model Integration: Can Understanding Biopsychosocial Gut-Brain Axis Mechanistic Pathways Improve our Clinical Reasoning in Primary Care?

ABSTRACT

INTRODUCTION: Most NPs practice in primary care settings. Cognitive tools to inform and advance NP understanding of biopsychosocial mechanisms can support early recognition, interdisciplinary collaboration, interventions, and prevention of negative outcomes. THEORY AND METHODS: We describe the development of a model to support NP consideration of gut-brain axis (GBA) evidence-based pathways, contributing variables, and related health outcomes. RESULTS: The model's outcomes are factors associated with homeostasis or disruption of biological, psychological, and social systems. DISCUSSION/CONCLUSION: This cognitive tool aims to support NP awareness of multi-domain GBA relationships to consider with differential diagnoses and clinical treatment of the "whole body system".
