Hazard: all climate-related hazards, heat
Part of: summary - Heat-Health Alerting system

Who this action card is for

This Heat-Health Alert (HHA) action card summarises the suggested actions that commissioners of health or social care settings (for example commissioners of health and social care services, local authorities, directors of public health, Integrated Care Systems (ICSs)) should consider to prepare for and respond to each HHA alert type:

actions to consider all year round to support summer preparedness
actions to consider for pre-summer readiness and summer preparedness
actions to consider for a yellow alert
actions to consider for an amber alert
actions to consider for a red alert

The actions are illustrative and organisations including the NHS, local authorities, Local Health Resilience Partnerships (LHRPs) and Local Resilience Forums (LRFs) should ensure that local plans are developed and in place for the coming summer as part of wider preparedness and response to extreme heat events.

In a clinical or care setting with a patient or client, staff should exercise professional judgement and respond appropriately to that patient’s needs. Staff should be aware of the effects of severe heat on health and when they notice a client or patient at risk of overheating, for example, from living in a home that is too hot, that they know what immediate actions to take to ensure safety and that there are clear guidelines for them to make other necessary arrangements (for example, addressing housing issues) in the immediate and longer term.

About the HHA action cards

The HHA action cards have been updated to reflect the new impact-based HHA warning systems, which have been developed in tandem with the Adverse Weather and Health Plan (AWHP). The AWHP, HHA action cards and associated documents provide a broad framework for action, and local areas and organisations need to tailor these good practice suggestions to their local needs and ensure that these fit with wider local arrangements. HHAs should trigger a series of actions by different organisations and professionals as well as the public, building upon year-round planning activities to ensure hot weather preparedness.

The action cards emphasise the importance of joint working across agencies including the voluntary and community sector, and highlight one of the aims of the plan, which is to ensure that there is an integrated response to severe weather events across sectors. Local areas will need to consider those actions indicated in the relevant section which will need to be taken jointly across organisations and sectors.

The action cards cover the core elements of heat-health action plans recommended by the World Health Organization (WHO) heat-health action plans guidance:

longer-term development and planning
preparation before the summer
prevention during the summer
specific responses to hot weather
monitoring and evaluation

Using HHA action cards

In line with other weather warning systems in operation within England (and the UK), warnings will be issued when the weather conditions have the potential to impact the health and wellbeing of the population. The alerts will be given a colour (yellow, amber or red) based on the combination of the impact the weather conditions could have, and the likelihood of those impacts being realised. These assessments are made in conjunction with the Met Office when adverse weather conditions are indicated within the forecast.

Yellow and amber alert assessments cover a range of potential impacts (for example impacts on specific vulnerable groups (such as rough sleepers) through to wider impacts on the general population) as well as the likelihood (low to high) of those impacts occurring. This additional information should aid making decisions about the appropriate level of response during an alert period. Within the alert that is issued, the combination of impact and likelihood will be displayed within a risk matrix as illustrated below.

Once the decision is made to issue an alert (yellow, amber, or red), these will be cascaded to those registered to receive the alerts and made available on the new dedicated web-platform. Alerts will be issued with as much lead time to the event as is possible to allow users time to make their local assessments and to initiate all appropriate actions to reduce harm to health. Users should review every alert when issued to ensure they fully understand the potential impacts and how likely they are to occur.

Figure 1. Impact and likelihood risk matrix

Green (summer preparedness)

No alert will be issued as the conditions are likely to have minimal impact and health. However, during periods where the risk is minimal it is important that organisations ensure that they have plans in place and are prepared to respond should an alert (yellow, amber, or red) be issued.

Yellow (response)

These alerts cover a range of situations. Yellow alerts may be issued during periods of heat in which would be unlikely to impact most people, but those who are particularly vulnerable (for example, the elderly with multiple health conditions and on multiple medications) are likely to struggle to cope and where action is required within the health and social care sector specifically. A yellow alert may also be issued if the confidence in the weather forecast is low, but there could be more significant impacts if the worst-case scenario is realised. In this situation the alert may be upgraded as the confidence in both the weather forecast and the likelihood of observing those impacts improves.

Amber (enhanced response)

An amber alert would represent a situation in which the expected impacts are likely to be felt across the whole health service, with potential for the whole population to be at risk and where other sectors apart from health may also start to observe impacts, indicating that a coordinated response is required. In addition, in some circumstances a National Severe Weather Warning Service (NSWWS) Extreme Heat warning may be issued in conjunction with and aligned to the UKHSA HHA. This situation would indicate that significant impacts are expected across multiple sectors.

Red (emergency response)

A red alert would indicate significant risk to life for even the healthy population. A red warning would be issued in conjunction with and aligned to a red NSWWS Extreme Heat warning. Severe impacts would be expected across all sectors with a coordinated response essential.

Suggested actions to consider all year round to support summer preparedness

Long-term, strategic actions would seek to address the 9 areas of action outlined in the Adverse Weather and Health Plan (AWHP), as appropriate locally, including:

service delivery
capacity building
organisational arrangements
communication
risk management
early warning systems
research and data analysis
quality assurance
policy development and accountability

Within these 9 areas of action, consideration should be given to:

Identify those at risk

Develop an understanding of the local population and groups who may be vulnerable to the impacts of hot weather on health through Integrated Care Partnerships (ICPs) as well as the Joint Strategic Needs Assessments (JSNAs) and other interagency arrangements.

Develop local strategic plans

Ensure Integrated Care Partnership (ICP) strategies and Joint Local Health and Wellbeing Strategies (JHWSs) address longer term resilience building for the population and infrastructure. Working with partner agencies, incorporate long term health improvement and organisational plans to prepare for and mitigate against the impact of hot weather. This includes how to identify and improve the resilience of those individuals and communities most at risk and ensuring that a local, joined-up programme is in place. Such plans should cover working with partner agencies, planning and infrastructure providers, and communities.

Working with partners

Work with partner agencies, providers, and businesses to coordinate Business Continuity Plans (BCPs) and/or hot weather plans, ensuring vulnerable and marginalised groups are appropriately supported. This may include developing and maintaining a register of the most vulnerable individuals to ensure they can be offered appropriate support where required.

Working with planning and other infrastructure providers

Planning and infrastructure providers could include:

housing (including loft and wall insulation and other plans to reduce internal energy use and heat production)
environmental action, planning and neighbourhood design, for example, increase trees and green spaces, external shading, reflective paint, water features and act on other infrastructure changes such as porous pavements

Working with communities

Engage the community and voluntary sector to support development of local community emergency plans

Commissioning processes

Consider preparedness for hot weather within commissioning processes.

Workplace champions

Consider identifying individuals to be workplace champions to increase staff awareness of the potential risks of adverse weather and climate change, and to encourage staff to embed best practice mitigation against, planning for and responding to adverse weather.

Training plans

Develop a training plan to ensure that health and social care providers and staff are aware of the local hot weather plans and are engaged in preparing for hot weather.

Ensure appropriate data-sharing agreements or protocols are in place to allow organisations to share data or intelligence, including details of the most vulnerable people where appropriate.

Surveillance and monitoring

Ensure surveillance and monitoring systems are in place to enable evaluation of the effectiveness of any hot weather interventions that are established locally, including locally relevant Public Health Outcomes Framework indicators and metrics.

Pre-summer readiness and summer preparedness

Figure 2. Impact and likelihood risk matrix: green

Suggested areas you can support preparedness are:

Alerts

Test out and ensure that national and organisational dissemination systems for heat health alerts are fully operational and effective, and that staff understand what actions to take. Review and update relevant distribution lists for information and weather alert cascades.

Audit

Complete an audit of organisational Business Continuity Plans (BCPs) and/or hot weather plans to ensure that these are up to date, including reviewing AWHP and HHA action cards to adapt suggestions for local circumstances.

Communication

Ensure staff are familiar with this action card, any relevant guidance, and your local plans before 1 June each year. Ensure care homes, GPs, primary and community care services, hospitals and other health and care providers are aware of the hot weather plan and are engaged in preparing for hot weather. Integrated Care Boards (ICBs) and Health and Wellbeing Boards may wish to consider monitoring the preparedness of local providers via their Integrated Care Partnership Strategies and Joint Local Health and Wellbeing Strategies.

Ensure other institutional establishments (for example, prisons, schools) are aware of hot weather guidance and hot weather plans.

Training

Ensure relevant staff members are aware of and understand BCP and/or hot weather plans, including ensuring relevant staff have received training where applicable.

Risk assessment of events

Local Licensing authorities should assure themselves that organisers of large-scale events for the summer period have taken appropriate risk assessment and mitigation of heat risks.
