Flu vaccination guidance updated for older patients

My Post (13)Public Health England (PHE) has updated its national immunisation guidance following evidence that adjuvanted trivalent influenza vaccines (aTIVs) work better for older patients than other flu jabs (PHE, 2017a).

The Green Book (PHE, 2017a), which features the latest information on vaccines and vaccination procedures in the UK, has been amended after the Joint Committee on Vaccination and Immunisation (JCVI) recommended aTIV, FLUAD®, for the 2018–19 flu season in its October meeting.

The Committee agreed that use of aTIVs in those aged 65 years and over is ‘more effective’ than current nonadjuvanted vaccines and ‘highly costeffective’ (JCVI, 2017).

Dr George Kassianos, national immunisation clinical lead for the Royal College of General Practitioners, said:

‘I very much welcome this guidance by the JCVI. Year on year, it is becoming more and more evident that conventional non-adjuvanted influenza vaccines do not provide sufficient protection for our older patients, particularly in years dominated by the influenza A(H3N2) virus, which dominated the flu season last year and the year before. Use of this adjuvanted vaccine is expected to result in fewer infections, fewer GP consultations and hospital admissions, and a significantly reduced winter burden on the NHS.

‘On the basis of the recent JCVI Meeting minutes outlining the clinical and cost-effectiveness evidence in elderly patients, GP practices are now able to seriously consider the adjuvanted flu vaccine for their patients aged 65 years and over for the 2018–19 flu season.’

Sharon Graham, senior lecturer in nursing at Staffordshire University and a former practice nurse, said:

‘In primary care we need to ensure that we can offer the most effective prevention against influenza to our patients aged over 65 years. This JCVI guidance will, I hope, help vaccinating health professionals to make the best choice of flu vaccine for next year’s season.’

Reasons behind the decision

Last year, PHE (2017b) declared conventional non-adjuvanted influenza vaccines provided little or no protection for over 65s in the 2016–17 flu season in the UK. This was recognised by the JCVI, who acknowledged ‘low influenza effectiveness’ in those aged 65–74 years throughout seasons affected by the A(H3N2) flu strain, and ‘non-significant vaccine effectiveness’ for all types of influenza in the over 75s (JCVI, 2017).

By comparison, the JCVI said aTIVs have ‘better immunogenicity and effectiveness’ in the elderly. While vaccine effectiveness decreases with increasing age and immunosenescence, a study from British Columbia used multivariate analysis to show vaccine effectiveness of around 60% in the elderly for aTIVs (Van Buynder et al, 2013). Almost half of the patients enrolled were aged over 85 years. Conversely, non-adjuvanted trivalent influenza vaccine was deemed ineffective. This is not uncommon, ineffectiveness of non-adjuvanted trivalent influenza vaccines in this patient population has been previously reported (Treanor et al, 2012).

A systematic review and meta-analysis of trivalent inactivated vaccine adjuvanted with MF59 found it was effective in reducing several influenza-related outcomes among the elderly, especially hospitalisations due to influenza-related complications (Domnich et al, 2017). It was also reported to be superior to non-adjuvanted vaccines.

Evidence presented at the European Scientific Working group on Influenza (ESWI) meeting in Riga, Latvia last September, revealed 1700 flu-related deaths could be prevented in those aged over 65 years who switched to an aTIV (Nguyen et al, 2017). Additionally, estimations by the researchers show as many as 195 600 cases of flu could be avoided. According to the researchers, this could reduce the number of GP visits by 21,800.

Research consultant and lead author of the study, Dr Van Hung Nguyen, said:

‘The model demonstrated that the adjuvanted vaccine had an incremental cost-effectiveness ratio of £3540 per quality-adjusted life year if used preferentially in those aged 65 years of age and over in the UK.

‘This is well within, and actually considerably below, the National Institute of Health and Clinical [sic] Excellence’s guideline threshold of £20 000 per quality-adjusted life year for medicines.’

Dr Marco Barbieri, from the Centre for Health Economics at the University of York, said:

‘Health economic analyses consistently show that more effective flu vaccines are very good value in older patients.

‘They reduce the number of GP consultations, A&E visits and episodes of serious illness and, of course, they help older people to remain healthy and independent.’ Commenting on the research presented at the ESWI, he said: ‘These data suggest that use of an adjuvanted influenza vaccine is a cost-effective option for the NHS immunisation programme.’

Mathematical modelling by PHE indicates the adjuvanted vaccine would be highly cost-effective in both the 65–74 and 75 year and over age groups, even under conservative estimates (PHE, 2017a).

Marketing authorisation of FLUAD®

The aTIV FLUAD® gained marketing authorisation in the UK in August 2017. It has been licensed in some countries in Europe since 1997 and in the US since 2015. According to its manufacturer, Seqirus, aTIV has superior seroconversion rates (the time period during which a specific antibody develops and becomes detectable in the blood) in the elderly, and superior geometric mean titres (the central number in a geometric progression of the concentration of a solution as determined by titration) in clinical risk groups against all three influenza vaccine types, compared to non-adjuvanted inactivated influenza vaccines.

Dr Russell Basser MD, chief medical officer of Seqirus, said:

‘We understand the devastating human impact of influenza infection in adults aged 65 years and older, the substantial societal impact of influenza, as well as the cost to the NHS in preventable GP appointments and preventable hospitalisations.

‘We believe that our strong and robust data on FLUAD®’s clinical efficacy, real-world effectiveness, and well-established safety profile, built up over 20 years of use, demonstrates convincingly that this adjuvanted influenza vaccine has clear advantages for adults aged 65 years and over when compared to existing conventional non-adjuvanted vaccines. We consider that FLUAD® can make a major contribution in reducing the burden of influenza on the health services, locally, regionally, and nationally.’

The company has recently announced a major investment in its Liverpool influenza vaccine manufacturing plant. This will allow-end-to-end manufacture of vaccines at the UK site, meeting growing demand and strengthening reliability of supply of FLUAD® for UK and global markets.

Is now the winter of our discontent? Exploring seasonal pressure on the NHS

My Post (1)Around this time every year, the media is strewn with forewarnings of how winter will put undue strain on the NHS. In a system already struggling to cope, there are concerns that the seasonal pressure pushes services to breaking point. The NHS’s ability to handle yearly increases in demand has led the British Red Cross to go as far as to call it a ‘humanitarian crisis’ (Campbell et al, 2017).

This article will consider the causes of winter pressure on NHS services and how they differ to those experienced throughout the rest of the year. It will explore whether the warnings are genuine or mere hyperbole, and look at some of the ways the NHS attempts to combat these pressures.

Causes of winter pressures

The leading cause of winter pressure is difficult to pinpoint, and can vary from year to year. However, there are a number of recurring contributing factors. While most health problems are not caused by extremes of cold, the weather indelibly has an effect on the number of patients attending accident and emergency (A&E) departments.

Cold weather increases the risk of heart attacks, strokes, respiratory illnesses, flu, falls and other diseases (NHS England, 2013; Public Health England, 2017). Vulnerable people— such as the very young, elderly and those with pre-existing conditions— are those predominantly affected by changes in the weather (National Institute for Health and Care Excellence (NICE), 2015). The effect of winter on the NHS becomes apparent in early December. Performance in A&Es is measured through their ability to meet a 4-hour waiting target. One of the core standards of the NHS Constitution states that a minimum of 95% of patients attending A&E departments in England must be seen, treated and then admitted or discharged in under 4 hours (NHS England, 2015). Breaches of the 4-hour waiting standard result in trusts having to pay penalties (House of Commons Health Committee, 2016).

A&E attendances
Annual attendances at A&E departments have increased. The number of people arriving at major (type 1) A&E departments has seen a 7% rise from 2010 to 2015—from an average of 36 731 attendances per day in August 2010, to 39 220 in August 2015 (Fisher and Dorning, 2016).

Consequently, only 87.9% of patients in type 1 departments were admitted, transferred or discharged within 4 hours in 2015–16 (House of Commons Health Committee, 2016). This is clearly far below the expected standard. The Royal College of Emergency Medicine (2016a) has estimated that the increased attendance over the past 5 years is equivalent to the workload of 10 additional medium sized emergency departments.

Contrary to expectation, the highest number of A&E attendances does not take place in winter. Instead, there is an observable ‘dip’ in visits to A&E around December and January (Fisher and Dornin, 2016). The highest overall attendances are actually in the summer months. The important factor affecting winter pressure is the number of patients subsequently admitted to hospital. The highest proportion of the patient population in summer is under 60 years of age. By contrast, in the winter, it tends to consist of those over 60 years. This spike in the number of more vulnerable, elderly patients is significant because they tend to stay longer in A&E, and are more likely to be readmitted to hospital (Fisher and Dornin, 2016).

Hospital admissions
Like attendances, hospital admissions have also increased. Similarly, they have seen a 7% rise from 13 723 in August 2010 to 14 666 in August 2015 (Fisher and Dornin, 2016). There is a notable ‘peak’ of admissions during the middle of winter (Fisher and Dornin, 2016).

The difference between the proportion of patients admitted is 27.9% in winter, compared with 25.8% in the summer months (Department of Health (DH) et al, 2017).

‘Congestive hospital failure’
The rise in hospital admissions has caused a subsequent decrease in the number of available hospital beds, with the percentage of beds occupied peaking in winter (Fisher and Dornin, 2016). Due to the number of beds available for admission of acutely ill and injured patients continuing to fall over the past 5 years, the UK now has the lowest number of beds per capita in Europe, and England has the lowest number within the UK (Royal College of Emergency Medicine, 2016a). The consequence of limiting bed capacity has been a growth in general and acute bed occupancy from 86.3% in 2010–11, to 91.2% in 2015–16 (Royal College of Emergency Medicine, 2016b).

A lack of available beds reduces flow through A&Es as it slows the accommodation of new attendances (Royal College of Emergency Medicine, 2016a). This in turn affects the ability of ambulance services to off-load patients—an issue known as ‘congestive hospital failure’ (NHS England, 2013).

Another factor influencing occupancy rates is delayed transfer of care, which leaves systems less resilient to operational pressures. Unnecessary delay in discharging patients who no longer need to be in hospital led to 1.15 million bed days being lost in acute hospitals during 2015 (National Audit Office, 2016).

Combatting pressures

To help combat winter pressures, the NHS conducts strategic planning each year. For the 2017/18 winter, formal planning began at its earliest time yet in July (Philip, 2017). Local plans were submitted in September covering resilience arrangements from the start of December up to Easter 2018.

As part of this preparation, Public Health England (2017) publishes a Cold Weather Plan every year to help protect the population against harm from cold weather. A mixture of past experience and forward-planning will help build future resilience. Below are some of the key methods of combatting pressure.

Best use of ambulance services
An expansion of the ‘hear and treat’ and ‘see and treat’ services provided by ambulance services can help alleviate demand on A&E departments. ‘Hear and treat’ services refer to 999 calls that are successfully completed without dispatching an ambulance vehicle response. Examples of this include over-the-phone advice, instructions for self-care, or referral to other urgent services (Urgent and Emergency Care Review Programme Team, 2015).

‘See and treat’ services refer to a model of care where a patient is clinically assessed at scene, before being provided with immediate treatment and subsequent discharge and/or referral (Urgent and Emergency Care Review Programme Team, 2015). By avoiding taking patients unnecessarily to A&E, they can be referred to more appropriate services that better fit the patient’s needs, or further support can be provided at home or in a community setting. ‘Hear and treat’ and ‘see and treat’ services now cover 3.5 million people (NHS England, 2017b).

This winter will see the full rollout of phase two of the Ambulance Response Programme, with the introduction of new call standards that accurately reflect the type and urgency of care needed by patients (Quaile, 2017). Along with the new dispatch on disposition system, giving call handlers more time to triage 999 calls, it is hoped that many patients can avoid being taken unnecessarily to A&Es.

Boosting flu vaccinations
Flu outbreaks within health services can be crippling and are a genuine concern each winter. Last year, 49% of NHS staff were vaccinated against the influenza virus and, this year, the number of vaccinated staff has been raised to 63% (NHS England, 2017b).

Additionally, free flu jabs will be provided to hundreds of thousands of care-home staff at a cost of up to £10 million; and numbers of vaccinations for young children and vulnerable people will be increased (NHS England, 2017a). Being vaccinated is the best way to prevent the spread of flu infection and reduce avoidable deaths. As it is possible to have flu without showing any symptoms, health professionals could find themselves working with flu but not realising it. It is essential they are vaccinated to avoid spreading the illness to vulnerable people.

Increasing funding
The spring budget announced an additional £100 million to support improvements in emergency departments through the implementation of a primary-care streaming model (Philip, 2017). Here, patients are streamed away from highly pressured emergency departments, to co-located GP-led primary care services, for conditions more suited to assessment and treatment in primary care (NHS Improvement, 2017).

Achieving ‘good’ patient flow
According to Monitor (2015), improving patient flow through hospital departments other than A&E is ‘the most important systemic means’ of avoiding sharp declines in A&E performance during winter. Health systems that have better patient flow are much better at coping with external pressures than those who don’t (NHS Improvement, 2017). Within ambulance services, good patient flow is seen as the handing over of a patient to an emergency department within 15 minutes of arriving (NHS Improvement, 2017).

My Post (2)Encouraging self-care
Further promotion of self-care is essential to reducing demand on health services. Giving people the confidence and information to look after themselves can help prevent ill health and reduce pressure (British Medical Association, 2016). However, for this to work, support needs to be easily accessible.

Improving housing conditions
Housing conditions for vulnerable people play an important part in the number of excess winter deaths and illnesses. In the coldest 10% of homes, the death rate rises approximately 2.8% for every degree Celsius drop in the outside temperature (NICE, 2015).

In England, there is a relatively sharp increase in the risk of death when outdoor temperatures fall to around 6°C (NICE, 2015). Improving heating and insulation for vulnerable people is therefore highly important for reducing avoidable illness or death.

Addressing growing GP demand
General practice is on the brink of crisis as a result of inadequate resourcing, an insufficient workforce, and an unsustainable workload (British Medical Association, 2016). The number of GP consultations in England rose from 303 million in 2008/9 to 361 million in 2013/14 (Royal College of General Practitioners, 2015). However, despite this 19% increase in demand, there has been no change in resourcing and staffing, putting undue strain on GP services (British Medical Association, 2016).

Increased funding in social care
Social care has been struck by considerable funding cuts in recent years, creating a knock-on effect on the number of people receiving services.

There were 500 000 fewer people who accessed social care in 2013/14 compared to 2008/9 (Franklin, 2015). This is despite an increasing ageing population, where the number of over-85s will double over the next two decades. It is also anticipated that adults with a learning disability will increase by at least a third (Local Government Association, 2016).

The cut of £5 billion in local authority social care budgets over the last 5 years has placed significant pressure on services (Local Government Association, 2016). Delays in arranging community nursing or social care has a considerable impact on delayed transfers, with 60% of trusts believing the increase in delayed transfers of care is owing to reductions in social care capacity (Monitor, 2015).

This article has sought to explain the reasons behind additional pressures on health services brought on by the winter season. While attendances at A&E are lower during the winter, the number of hospital admissions of vulnerable patient groups rises, largely because of seasonal illnesses such as flu and norovirus. This causes a reduction in the number of beds available and reduced patient flow within hospitals.

To combat these pressures, longer term investments are needed to address the insufficient workforce, lack of social care, and demand on primary care services. Although there has been additional investment in vaccination against flu; primary-care streaming; and resilience funding for ambulance services for this winter; it is unclear what impact—if any—this will have on health services.
