Care Coordination and Continuity

Care coordination is the deliberate organization of a patient's care activities and the sharing of information among everyone involved, so that care is delivered as a coherent whole rather than as disconnected encounters. Continuity — the experience of connected, consistent care over time and across settings — is the result that coordination aims to achieve, and transitions between settings are where it is most at risk.

Definition

Care coordination is the deliberate organization of patient-care activities and information-sharing among the participants involved in a patient's care to achieve safer and more effective care; continuity of patient care is the degree to which a series of discrete care events is experienced as coherent and connected over time.

Scope

This entry covers what care coordination and continuity mean, the points of vulnerability at transitions such as hospital discharge, and the interventions and evidence aimed at improving them. It treats coordination as an organizational and delivery topic within health services research and does not give clinical instructions.

Core questions

• How can the activities of multiple providers and settings be organized into coherent care?
• Why are transitions between settings, such as hospital discharge, especially risky?
• Which interventions reduce gaps in information transfer and follow-up?
• How do coordination and continuity relate to safety, readmissions, and patient experience?

Key concepts

• Care transitions
• Information transfer and handoffs
• Discharge planning
• Medication reconciliation
• Informational, relational, and management continuity
• Readmissions and post-discharge adverse events

Key theories

Transitional care

Coleman and colleagues developed and tested the idea that supporting patients and caregivers through transitions between settings — through coaching, medication self-management, and a shared care record — reduces post-discharge failures, demonstrating in a randomized trial that a structured transitions intervention lowered readmissions.

Mechanisms

When responsibility for a patient passes between providers or settings, information and accountability can be lost, producing adverse events and avoidable readmissions; cohort studies show a substantial share of patients experience adverse events shortly after hospital discharge, often related to medications and incomplete follow-up, and systematic reviews document frequent deficits in communication between hospital and primary care physicians. Coordination works by closing these gaps — transferring accurate information, reconciling medications, clarifying who is responsible, and supporting patients through the transition — so that discrete encounters connect into continuous care. Strong primary care contributes by sustaining a longitudinal relationship that anchors continuity.

Clinical relevance

Coordination and continuity affect whether patients fall through the cracks between providers, particularly after hospital discharge, with consequences for safety and readmission. This entry describes coordination as an organizational property of the delivery system and the evidence on improving it; it is reference material, not guidance for managing an individual patient.

Epidemiology

Studies of the post-discharge period find that a meaningful proportion of patients experience adverse events after leaving the hospital, and reviews report that information often fails to reach the primary care physician in time for the first follow-up visit, marking transitions as a recurrent source of risk across systems.

Evidence & guidelines

The evidence base includes randomized trials of transitional-care interventions such as Coleman's Care Transitions Intervention, cohort studies of post-discharge adverse events by Forster and colleagues, and systematic reviews of hospital-to-primary-care communication by Kripalani and colleagues, complemented by the primary-care continuity evidence synthesized by Starfield.

History

As care became more specialized and dispersed across settings, the fragmentation of patients' care drew growing attention, especially around hospital discharge. Cohort and review evidence in the early 2000s quantified post-discharge adverse events and communication failures, and randomized transitional-care models such as Coleman's intervention provided tested approaches, establishing care coordination and continuity as priorities for delivery-system organization and safety policy.

Debates

Which dimension of continuity matters most?

Continuity is variously understood as informational (records following the patient), relational (an ongoing personal clinician relationship), and management (consistent care plans); which dimension most affects outcomes, and how to balance them in fragmented systems, remains debated.

Frequently asked questions

What is the difference between care coordination and continuity?

Care coordination is the deliberate work of organizing a patient's care activities and sharing information among those involved; continuity is the outcome that work aims for — the experience of connected, consistent care over time and across settings.

Why are care transitions considered high-risk?

At transitions such as hospital discharge, information and accountability can be lost between providers; studies show many patients experience adverse events soon after discharge and that information often fails to reach the primary care physician in time, which is why transitions are a focus of coordination efforts.
