Introduction

The National Health Service (NHS) began on 5th July 1948, as a great and novel undertaking. Since the early 1950s, the budget of the NHS has increased significantly over time. One of the common reasons why we need a new upgraded system is the rise of the ageing population. This increase is not just seen in the UK but all around the world. It is a problem with which all health systems in the world are struggling. 

Another reason for the proposed upgrade is the results of several studies over the years. These studies suggest that the odds of dying if admitted during the weekend are greater than if admitted on a weekday. The concept of a Seven-Day NHS represents a significant shift in how healthcare is delivered. It aims to make comprehensive medical services available throughout the entire week, including weekends.

This addresses the long-standing issues associated with limited service availability. In this article, we will explore the motivations behind the Seven-Day NHS and examine its benefits. Furthermore, we will identify the challenges it poses, and consider case studies that illustrate successful and unsuccessful implementations.

The existing system and a new proposal

Historically, the UK's National Health Service (NHS) operated on a five-day workweek model. Full services were available from Monday to Friday with capacity reduction over weekends and public holidays. The services were aligned with typical business hours. During weekdays, they focused on

• Outpatient services
• Elective surgeries 
• Other scheduled medical care 

This traditional approach led to several systemic challenges. The greatest challenge was the reduced weekend capacity which resulted in longer waiting times for patients. This was particularly true for diagnostic tests, speciality consultations, or elective procedures. The resulting backlog led to 

• Delayed treatments 
• Suboptimal care 
• Limited range of services for patients requiring urgent or emergency care 

All of these factors had a direct impact on health outcomes and treatment satisfaction.

In December 2012, National Health Services (NHS) published “Everyone Counts: Planning for Patients 2013/2014”. In that document, plans for seven-day access to NHS services in the UK were outlined. This led to the formation of the “NHS Services, Seven Days a Week” project. It aimed to improve the access to diagnostic, urgent and emergency services across the seven days of a week.¹ The rationale behind these changes is fourfold:² 

1. Reduce excess weekend mortality 
2. Enhance cost-efficiency 
3. Align the NHS with the retail sector's operational model 
4. Improve overall patient satisfaction

Since then, the UK has been progressively transitioning to a seven-day healthcare model. It aims to address these issues by offering continuous service throughout the week. This shift was driven by the realisation that healthcare demands do not adhere to a typical work week. The push for a Seven-Day NHS also aligned with broader healthcare reforms and government policy objectives. These reforms and policies aim to improve public health outcomes and patient satisfaction.

What are the key features of the Seven-Day NHS?

The proposed model addresses the limitations inherent in a traditional five-day system. The Seven-Day NHS offers a comprehensive and accessible approach to medical care, as follows:

Extending window hours for better access

One of the main principles of the Seven-Day NHS is that health services are offered seven days a week. This often comes with 

• Expanded hours 
• Accommodating patient needs 
• Ensuring better accessibility 
• Reducing bottlenecks in the traditional system

Full range of services and enhanced emergency services

The Seven-Day NHS allows comprehensive medical services across the entire week. These include services which were previously unavailable on the weekend, such as

• Diagnostic tests
• Imaging services 
• Specialist consultations 
• Surgical procedures 
• Other critical healthcare services 

The Seven-Day NHS also permits strengthened emergency response, with more staff on weekends. This staff includes key personnel like surgeons, anesthesiologists, and critical care nurses.

Integrated technology and communication systems

The Seven-Day NHS scheme uses robust technology to maintain seamless operations throughout the week. Examples are electronic health records (EHRs), telemedicine, and communication and patient information that can be accessed across different shifts.

Focus on patient-centred care

The Seven-Day NHS emphasizes patient-centred care by providing services throughout the week. By doing so, the healthcare system becomes more flexible and responsive to patient needs.

• More appointment slots
• Reduced waiting times 
• Enhanced patient flexibility

Emphasis on staff well-being and work culture

The successful implementation of the Seven-Day NHS depends on a healthy and motivated workforce. As part of this feature, healthcare organizations must prioritize staff well-being and work-life balance. Support programs, flexible scheduling, and measures to prevent burnout are implemented to maintain a sustainable operation.

What are the benefits of the seven-day NHS?

Improved patient outcomes

One benefit is allowing more consistent and timely access to healthcare services. This contributes to improved patient outcomes. Timeliness can lead to earlier diagnosis and treatment. Doing so reduces the risk of complications and enhances recovery.

Waiting time drop

Offering services throughout the week reduces the waiting time. This is especially beneficial for patients requiring urgent care or those with busy schedules. It also reduces the strain on healthcare facilities during weekdays by distributing patient demand more evenly across the week.

Enhanced resource utilization

With a steady flow of patients across the week, healthcare facilities can better manage their capacity. Doing so reduces congestion and improves workflow. The resulting enhanced efficiency can lead to 

• Cost savings 
• Better resource allocation 
• Improved overall system performance

Better patient experience

By providing flexibility and convenience, patients can schedule appointments at times that fit their personal or work commitments. This reduces the need to take time off or arrange special accommodations.

Much better emergency services

The Seven-Day NHS ensures a consistent and comprehensive response capability every day of the week, with additional staffing and resources on weekends. Emergency departments can therefore respond more effectively to patient needs.

Continuity of care

The new scheme allows healthcare providers to offer consistent services throughout the week. Doing so is crucial for 

• Managing chronic conditions 
• Providing follow-up care 
• Ensuring that treatment plans are not disrupted by weekend closures

Flexibility for healthcare professionals

The Seven-Day NHS introduces greater flexibility in staffing and work schedules. This allows healthcare professionals to choose shift-based arrangements. A more flexible workforce leads to 

• Better morale 
• Lower turnover rates 
• A more sustainable healthcare system

Public health benefits

The Seven-Day NHS contributes to broader public health benefits. This is achieved by ensuring continuous access to preventive care and health screenings. The resulting consistent availability can also increase the reach of public health initiatives, such as vaccination programs and health education. Ultimately, consistent access to healthcare services improves community health outcomes.

Reduced pressure on weekday services

By spreading the demand for healthcare services across the entire week, the Seven-Day NHS reduces pressure on weekday operations.

Challenges and criticisms of the Seven-Day NHS

Workforce and work-life balance

The Seven-Day NHS aims to offer consistent healthcare across all days of the week. However, it poses significant challenges in workforce planning. Ensuring adequate staff coverage for all shifts, including weekends and nights, can lead to shortages, particularly in specialized roles. An internal Department of Health report indicated that an additional 11,000 staff members would be required to achieve a seven-day NHS, including 4,000 more doctors. This would break down into 

• 1,600 consultants
• 1,500 registrars 
• 900 junior doctors 

These estimates were based on the staffing levels needed to provide the same level of coverage on weekends as on weekdays.³ This shift-based work schedule may disrupt healthcare professionals' work-life balance, contributing to stress and burnout.

Legal constraints

Operating a seven-day healthcare system may require changing existing contracts and employment terms. This change raises legal and ethical considerations regarding 

1. Employment practices 
2. Workers' rights 
3. Patient safety 

Healthcare organizations must ensure that staffing models comply with labour laws and regulations. At the same time, these organizations need to maintain a safe and fair working environment for their employees.

Higher operational costs

The Seven-Day NHS comes with increased operational costs due to extended hours, additional staffing, and other logistical needs. These higher expenses can strain healthcare budgets, especially in public healthcare systems with limited resources. Finding a sustainable financial model is a key challenge in implementing this approach.

Resistance to change

Transitioning from a five-day to a seven-day healthcare model can meet resistance from healthcare professionals, administrators, and patients. This resistance could stem from concerns about 

1. Work-life balance
2. Resource allocation
3. The necessity of the change

Successful implementation requires clear communication, stakeholder engagement, and a compelling vision for the benefits of a seven-day system.

Continuity and coordination of care

Effective seven-day healthcare requires 

• Seamless coordination among healthcare teams 
• Robust communication systems 
• Efficient handovers between shifts 

Any breakdowns in these areas can lead to inconsistencies in care delivery. This can affect patient outcomes. Ensuring smooth transitions between shifts is crucial for maintaining high-quality care.

The practicality

The shift towards a seven-day healthcare model in the UK aims to address higher mortality rates observed during weekend emergency admissions. Data from the Hospital Episode Statistics (1 April 2010 - 31 March 2011) indicate a 30-day mortality rate of 3.70% for weekday admissions and 4.05% for weekend admissions. While the objective is to reduce weekend mortality, the cost of implementing comprehensive seven-day services is estimated to be between £1.07 billion and £1.43 billion.

Unfortunately, this exceeds the NICE (National Institute for Health and Care Excellence) budget threshold by £339 million, raising it to £831 million. Despite these considerable costs, there is insufficient evidence that seven-day services will effectively lower weekend mortality rates or avoid impacting weekday admissions.^4,5

A way forward

The current system has a significant shortcoming: there is a noticeable difference in the quality of care between weekdays and weekends. This indicates that improvements are needed. However, trying to offer a seven-day service with resources and staffing intended for a five-day setup is impractical. A quote from Abraham Lincoln seems appropriate here: “We can complain because rose bushes have thorns, or rejoice because thorn bushes have roses”. So ensuring effective delivery of a five-day service requires a comprehensive approach.

Such an approach involves not just sufficient consultant coverage, but also more social workers, healthcare assistants, nurses, junior doctors, porters, and radiographers. This focus is necessary to maintain functionality in acute and emergency services, before even considering expanding routine elective care to weekends.
