Effective communication skills of medical staff and their relationship to the effectiveness of services provided to patients

Abstract

Effective communication between medical staff and patients is a core determinant of healthcare quality, influencing patient satisfaction, adherence, safety, and clinical outcomes. This article synthesizes conceptual models and empirical evidence to examine how communication skills of physicians, nurses, and allied health professionals relate to the effectiveness of services provided to patients. Drawing on systematic reviews, experimental and observational studies, and measurement literature, we outline communication components (verbal, nonverbal, informational, relational), mechanisms by which communication affects outcomes, and the evidence linking communication skills to service effectiveness across settings and populations. We also examine contextual and moderating factors (patient age, health literacy, organizational systems, inter-professional communication), practical strategies for training and assessment, and implementation considerations for embedding communication improvement into routine care. The review highlights consistent associations between better communication and higher patient satisfaction, improved adherence, more accurate diagnosis and shared decision-making, reduced adverse events, and better patient-centred outcomes—particularly among older adults and vulnerable groups. Finally, we propose a framework for practice improvement and research priorities to advance measurement, intervention design, and system-level adoption of communication best practices.
