Loneliness as a Vital Sign: Toward a Biopsychosocial Reframing of Social Disconnection.

Background: Loneliness is increasingly recognized as a major determinant of health rather than a transient emotional experience. Extensive evidence links chronic loneliness to adverse physical and mental health outcomes and increased healthcare utilization. Despite growing policy attention, loneline...

Extensive evidence links chronic loneliness to adverse physical and mental health outcomes and increased healthcare utilization. Despite growing policy attention, loneliness remains inconsistently identified and addressed in healthcare systems, particularly in primary care, where other social determinants of health are increasingly screened. Objective: This narrative synthesis aims to advance a biopsychosocial reframing of loneliness as a "vital sign" to reflect a clinically relevant, measurable, and actionable health metric that can be feasibly integrated into primary care workflows to inform whole-person care, risk stratification, and referral pathways. Methods: A literature search of interdisciplinary peer-reviewed manuscripts published between 2010 and 2025 across public health, psychology, gerontology, and translational health sciences. Included sources encompassed epidemiological studies, mechanistic research, and implementation science literature examining loneliness screening and integration within real-world clinical workflows. Results: Results are presented thematically to reflect the manuscript's objective of reframing loneliness as a clinically actionable vital sign. Findings are organized to reflect evidence supporting loneliness as a biopsychosocial health risk; feasibility and validity of brief loneliness screening tools in primary care; and implementation determinants influencing adoption, sustainability, and equity, aligning empirical evidence. Synthesized evidence demonstrates that loneliness influences health through interconnected biopsychosocial pathways shaped by structural inequities and marginalization across the life course. Brief, validated screening tools are feasible for use in time-constrained primary care settings, particularly when embedded into existing workflows. Implementation evidence indicates that electronic health record prompts, brief clinician training, and clear referral pathways enhance feasibility and acceptability, while clinician emotional labor, time pressures, and organizational readiness are key determinants of sustainability. Conclusions: Conceptualizing loneliness as a vital sign offers a translational pathway to normalize assessment, reduce stigma, and integrate social connection into biopsychosocial models of care. Theory-informed implementation strategies are essential to support adoption, equity, and long-term maintenance. This reframing positions primary care as a critical site for early identification and intervention and underscores the central role of health, clinical, and community psychology in advancing whole-person, socially responsive healthcare.
