The Revolving Door: Why Continuity of Care Matters More Than Ever
"Navigating the challenges of fragmented healthcare in the modern NHS."
The National Health Service (NHS), since its inception, has strived to provide comprehensive healthcare to all. Debates about its future often revolve around finances and management, frequently overshadowing the patient's perspective. A stable, consistent approach to medical care is crucial, allowing healthcare professionals to understand the patient's history, build trust, and make well-informed decisions.
However, a growing concern is the lack of continuity of care, where patients encounter a revolving door of different doctors and specialists. This fragmentation undermines the quality of care, erodes patient confidence, and ultimately affects health outcomes. The experience of one physician, detailed in a letter to the BMJ, illustrates this growing problem within the NHS, highlighting the frustrations and potential dangers of a system that prioritizes efficiency over personalized care.
This article examines the importance of continuity of care, dissects the issues contributing to its decline, and offers insights for both patients and healthcare providers on how to navigate and improve the current system.
The Scope of Care Fragmentation
Care fragmentation remains a persistent challenge across healthcare systems, with ambulatory care fragmentation linked to subsequent hospitalization risk, underscoring its clinical consequences. Research has established that fragmented care delivery negatively affects outcomes for patients with chronic illnesses, compounding the burden of long-term disease management. Addressing fragmentation is considered important not only for improving care coordination but also for reducing health disparities and improving access to preventive services. Despite growing recognition of the problem, researchers continue to call for stronger theoretical frameworks to understand the mechanisms by which fragmentation drives adverse outcomes.
How Fragmentation Is Measured—and Where It Falls Short
Care fragmentation, care continuity, and care coordination are related but distinct concepts, and conflating them has historically muddied both research and practice. Studies have typically relied on administrative claims data as the gold standard for measuring continuity, yet this approach captures only structural patterns of provider utilization and may miss qualitative dimensions of the patient experience. A dual-measure approach—distinguishing continuity within a single practice from continuity across all providers—has been proposed to better clarify where fragmentation occurs. In systems characterized by high provider choice, such as Sweden's, achieving relational continuity is especially challenging because patients frequently move between different care settings and providers.
A Longstanding Problem in Modern Medicine
The concept of continuity of care has roots stretching back decades in primary care philosophy, though it gained particular urgency as healthcare systems grew more specialized and compartmentalized in the late twentieth century. Early quality-of-care frameworks recognized that a patient's relationship with a consistent provider was foundational to effective treatment, particularly for chronic conditions requiring long-term management. Over time, the proliferation of specialists, the rise of hospitalist medicine, and the shift toward outpatient care delivery created new structural barriers to continuity. While no single breakthrough moment defines the field, the accumulation of evidence linking fragmented care to poorer outcomes has steadily elevated continuity from a clinical ideal to a measurable quality metric.
The Fragmented Reality: Losing the Personal Touch in Healthcare
The core issue lies in the increasingly fragmented nature of healthcare. Patients often find themselves shuffled between numerous healthcare professionals, each with limited knowledge of their overall medical history. This is vividly illustrated by the physician's account of being seen by 17 different registrars without a single reassessment by a consultant. Such experiences are not only frustrating but can also lead to critical oversights in treatment and care.
- Lack of Holistic Understanding: Each new healthcare provider only sees a snapshot of the patient's health, missing the long-term trends and subtle nuances that are crucial for accurate diagnoses and effective treatment.
- Erosion of Trust: The constant change in personnel makes it difficult for patients to build trust and rapport with their healthcare providers. This can lead to patients feeling unheard and misunderstood, impacting their willingness to adhere to treatment plans.
- Increased Risk of Medical Errors: Without a consistent overview of the patient's medical history, the risk of errors such as conflicting prescriptions or missed allergies significantly increases.
- Inefficient Care: Redundant tests and consultations become common as each new doctor requires the patient to repeat their story and undergo similar evaluations, wasting time and resources.
Hospital-to-Community Transitions Under the Microscope
Continuity of care is recognized as a core component of high-quality, patient-centered health systems and a central domain of nursing practice, especially for older adults and those living with chronic and complex conditions. Discontinuities remain common during transitions between hospital and community care, contributing to fragmented communication, delayed follow-up, and negative patient outcomes. A 2026 review of continuity across hospital-to-community transitions highlights that these gaps are systemic rather than isolated, reflecting broader organizational and communication failures. The research underscores the need for structured transition protocols and coordinated handoff processes to bridge the gap between inpatient and community-based care.
Fragmentation as a Systemic Failure
Fragmentation has been characterized as a fundamental problem underlying the broader healthcare crisis, one that demands integrative solutions rather than piecemeal fixes. Economists and health services researchers have drawn explicit parallels between fragmentation measures and care continuity metrics, noting that they are essentially capturing the same phenomenon from opposite directions. The problem extends beyond general medicine: parents of children with disabilities, for example, face particularly disjointed care pathways as systems shift from institutional models to home- and community-based care, placing new demands on families and providers alike. These structural failures suggest that fragmentation is not merely a measurement challenge but a design flaw embedded in how modern healthcare systems are organized.
Variation Across Systems and Populations
While care fragmentation is a universal challenge, its magnitude and manifestation vary significantly across different healthcare systems, patient populations, and geographic contexts. Systems with greater provider choice and less gatekeeping—such as those found in parts of Northern Europe and in U.S. fee-for-service models—tend to exhibit higher rates of fragmentation, whereas more integrated systems with strong primary care gatekeeping may mitigate some of these effects. The degree to which fragmentation affects outcomes also depends on the patient population: those with multiple chronic conditions, limited health literacy, or socioeconomic disadvantage tend to be disproportionately affected. These variations suggest that interventions to improve continuity must be tailored to the structural and demographic realities of each system rather than applied as one-size-fits-all solutions.
Rebuilding Continuity: A Path Forward
Restoring continuity of care requires a multi-faceted approach involving healthcare providers, policymakers, and patients themselves. Healthcare systems must prioritize building structures that foster long-term doctor-patient relationships. This includes promoting team-based care models, improving communication and coordination among healthcare professionals, and implementing technology solutions that provide a holistic view of the patient's medical history. By addressing these challenges, we can pave the way for a healthcare system that values both efficiency and personalized care, ultimately leading to better health outcomes and improved patient satisfaction.
Connecting the Evidence
The body of research on care fragmentation converges on a central insight: continuity of care is not a luxury but a structural prerequisite for effective, equitable healthcare delivery. Evidence from ambulatory care studies, transition-focused reviews, and system-level analyses collectively demonstrates that fragmentation drives preventable hospitalizations, worsens chronic disease outcomes, and deepens health disparities. Measurement remains an active area of debate, with researchers advocating for multi-dimensional approaches that capture both structural continuity and the patient-provider relationship. Ultimately, the consensus is that reducing fragmentation requires coordinated action across clinical practice, health system design, and health policy.
Toward Integrated Care Continuum
Looking ahead, the care continuum is increasingly viewed as a longitudinal, patient-centered framework that provides consistency across discrete healthcare encounters while accounting for medical needs and personal context. McKinsey's 2026 healthcare trends analysis identifies ambulatory care as an area of both challenge and opportunity, suggesting that innovations in outpatient delivery models may help address fragmentation at its source. Effective coordination between stakeholders across the care continuum—primary care providers, specialists, hospitals, community health organizations, and payers—is seen as essential to improving both quality and affordability. The shift from volume-based to value-based care models offers a structural incentive to invest in continuity, though implementation remains uneven across the U.S. healthcare landscape.
The Structural Roots of Discontinuity
Care fragmentation does not arise from individual clinician failures but from the structural logic of modern healthcare systems, which have evolved to optimize specialized episodes of care rather than longitudinal patient relationships. The fee-for-service payment model historically rewarded throughput over continuity, incentivizing referrals and procedural volume rather than coordinated, relationship-based care. Health information systems, while increasingly interoperable, still struggle to deliver seamless data sharing across institutional boundaries, leaving patients to serve as their own care coordinators. Addressing these systemic challenges requires not only clinical innovation but also fundamental rethinking of payment structures, health IT infrastructure, and workforce organization.
What Fragmentation Means for Patients
Behind the metrics and policy debates, care fragmentation has tangible consequences for real patients—particularly Medicare beneficiaries, who often navigate complex care landscapes involving multiple providers and settings. Research on primary care redesign has examined how interpersonal continuity and fragmentation evolve over time, finding that patients with highly fragmented care at baseline face persistent challenges even within redesigned care models. Experts emphasize that understanding why fragmentation occurs is a necessary precursor to developing evidence-based strategies that reduce its associated harms. The human cost of fragmentation is measured not only in hospitalizations and costs but in patient confusion, duplicated tests, medication errors, and erosion of trust in the healthcare system.
