Understanding and Addressing Stranded and Super-Stranded Patients in the NHS

Why this topic matters

Stranded and super-stranded patients represent a substantial and often avoidable burden on NHS resources. Their presence directly contributes to increased average length of stay (ALoS), reduced bed availability, and delays in admitting patients from emergency departments or elective waiting lists. This can lead to:

• Compromised patient safety and experience: Prolonged stays can increase risks of healthcare-associated infections, deconditioning, and overall dissatisfaction.
• Increased costs: Longer hospital stays incur higher operational costs for the organisation.
• Reduced capacity: Beds occupied by patients who are medically optimised for discharge but cannot leave contribute to 'corridor care' and elective surgical cancellations.
• Staff morale impact: Managing bed pressures and patients who are ready for discharge can be frustrating and demoralising for clinical teams.

Addressing the challenges posed by stranded and super-stranded patients is therefore critical for improving hospital performance, enhancing patient care, and ensuring the sustainable delivery of healthcare services.

Practical explanation

The terms 'stranded' and 'super-stranded' refer to patients whose hospital stay extends significantly beyond the expected or medically necessary duration for their condition. The definitions typically revolve around a specific timeframe relative to the average length of stay (ALoS) for similar diagnoses or procedures.

• Stranded Patient: A patient is generally considered 'stranded' if their length of stay (LoS) is 7 days or more, OR three times the average length of stay for their Healthcare Resource Group (HRG). The '7 days or more' criterion is often the more commonly applied and easily measurable benchmark.
• Super-Stranded Patient: A 'super-stranded' patient is typically defined as a patient whose length of stay is 21 days or more. This cohort represents an extreme form of stranding, often involving complex discharge planning needs.

It's important to note that these definitions can be locally adapted or refined by individual NHS Trusts based on their specific patient populations, service models, and data capabilities. The core principle, however, remains consistent: identifying patients whose stay is abnormally prolonged.

Why do patients become stranded?

The reasons are multifactorial and often represent systemic issues rather than individual patient factors alone. Common contributors include:

• Delayed Discharge (DToC): This is the single biggest driver. It occurs when a patient is medically fit for discharge but is awaiting onward care, packages of care, nursing home placements, or social care assessments. Factors include lack of social care capacity, delays in community service provision, or complex family situations.
• Internal Hospital Delays: Delays in diagnostic tests, specialist consultations, theatre availability, or internal transfers can extend stays beyond medical necessity.
• Complex Medical Needs: Patients with multiple co-morbidities or requiring highly specialised rehabilitation can predictably have longer stays, but even within these groups, preventable delays can occur.
• Patient and Family Choice: Sometimes, delays are due to patient preferences for specific care arrangements or family disagreements about discharge plans.
• Limited Community Pathways: An inadequate range or capacity of community services (e.g., intermediate care, rapid response teams, reablement) can create bottlenecks.
• Poor Discharge Planning: Ineffective or late initiation of discharge planning, lack of multidisciplinary team (MDT) communication, or insufficient patient/family involvement.

Common pitfalls

Addressing stranded and super-stranded patients effectively requires a systematic approach, but several common pitfalls can hinder progress:

• Focusing solely on individual patients: While individual patient review is crucial, systemic issues causing stranding must be identified and addressed. A 'firefighting' approach without addressing root causes is unsustainable.
• Lack of standardised definitions and data: Inconsistent definitions across departments or lack of reliable data can impede accurate measurement, trend analysis, and accountability.
• Blame culture: Attributing blame to specific teams (e.g., social care, community services) rather than collaborating to solve shared problems is counterproductive.
• Discharge planning starting too late: Waiting until a patient is medically fit for discharge to begin planning almost guarantees delays.
• Underestimating the 'super-stranded' impact: These patients consume a disproportionate amount of resources and often require intensive, proactive management.
• Failure to involve all stakeholders: Effective discharge planning and flow requires input from medical, nursing, allied health professionals, social care, pharmacy, and administrative teams, as well as the patient and their family.

Step-by-step approach to identifying and managing stranded patients

An effective strategy for tackling stranded patients integrates data-driven identification with proactive, multidisciplinary interventions.

1. Establish clear definitions and data capture

• Define 'stranded' and 'super-stranded': Agree on consistent, measurable definitions for your organisation (e.g., LoS >7 days or >21 days) and communicate these widely.
• Implement robust data capture: Ensure systems can accurately track patient LoS, expected date of discharge (EDD), and reasons for delay (e.g., DToC codes).

2. Daily Identification and Escalation

• Ward-based huddles/boards: Regular, brief multidisciplinary team (MDT) huddles (daily or several times a week) using visual boards to review all patients, specifically highlighting those nearing or exceeding stranded definitions.
• Proactive identification: Identify patients at risk of becoming stranded early in their admission, particularly those with complex needs or known discharge challenges.
• Digital tracking: Utilise digital patient flow systems to flag patients against the definitions, allowing for rapid identification by ward teams and flow managers.

3. Multidisciplinary Team (MDT) Approach

• Early and continuous discharge planning: Discharge planning should begin on admission. This includes assessing needs, involving social care, reviewing home environment, and engaging family/carers.
• Regular MDT reviews: Dedicated weekly or bi-weekly MDT meetings specifically for stranded and super-stranded patients, involving medical, nursing, therapy, social care, pharmacy, and ideally, community liaison teams. Focus on barriers to discharge and actions to overcome them.
• Set Expected Date of Discharge (EDD): A clearly communicated and updated EDD is a key driver for focused MDT work.

4. System-level Interventions

• Integrated care pathways: Develop and strengthen pathways between acute hospitals, community services, and social care to ensure seamless transitions.
• Intermediate care support: Invest in and utilise services such as 'discharge to assess' (D2A), reablement, and community rehabilitation to bridge the gap between hospital and home.
• Leadership oversight: Senior operational and clinical leaders should regularly review stranded patient data, discuss bottlenecks, and drive escalation processes for system-level issues.
• Shared accountability: Foster a culture where all teams understand their role in facilitating timely discharge.

5. Patient and Family Engagement

• Early communication: Discuss discharge plans and potential anticipated challenges with patients and their families as early as possible.
• Patient and family involvement: Empower them to participate in decision-making and preparedness for discharge.

Example in clinical practice: The daily 'Flow Huddle'

Consider an acute medical ward facing persistent issues with patient flow and a high number of patients often 'super-stranded'. To address this, the ward implements a structured daily 'Flow Huddle'.

Every morning at 08:30, the ward sister, junior doctor, ward consultant, physiotherapist, occupational therapist, and a representative from the discharge team gather around a large whiteboard. Each patient's bed is listed, along with their primary diagnosis, current medical status, and most recent Expected Date of Discharge (EDD).

During the huddle, specific attention is paid to:

• Patients nearing or exceeding 7 days LoS: These are flagged in yellow. The team discusses what specific actions are needed today to progress their discharge (e.g., 'awaiting physio review', 'needs social care assessment request sent', 'family meeting booked to discuss care package options').
• Patients at 21+ days LoS ('super-stranded'): These are flagged in red. For these patients, a more in-depth discussion occurs. The consultant leads a review of all outstanding actions, who is responsible, and any perceived blocks. For example, a patient might be medically fit but awaiting a specific nursing home placement. The discharge team representative then outlines the options being explored and a clear action plan for the next 24-48 hours.

The huddle concludes with clear, assigned actions and deadlines for each patient. By focusing daily on those at risk of stranding or already stranded, the ward team pro-actively manages discharge pathways, identifies system issues early, and ensures everyone is aligned on the next steps for patient progression. Over time, this leads to a noticeable reduction in average LoS and improved patient flow.
