Care Homes Strategy for Infection Prevention & Control of Covid-19 Based on Clear Delineation of Risk Zones

This is a holding page for the document Care homes strategy for Infection Prevention & Control of Covid-19 based on clear delineation of risk zones.

We also have a zip file for IPC signage that can be adapted.

This strategy incorporates as much current UK government guidance as possible, while remaining both consistent and pragmatic. On 15th May, we undertook a mapping of current guidance on infection prevention and control in care homes from the UK Government and Public Health England in order to understand the strengths and gaps, and to show how it relates to our strategy and the rationale for where it differs.

Update: since going online on 18th April, our strategy has been discussed and cited at various levels and made it into the following documents:

– Gordon, A.L. et al (2020) Commentary: COVID in care homes—challenges and dilemmas in healthcare delivery. Age and Ageing 2020, p.3.
– Carter, R. (2020) Covid-19: The support UK care homes need to survive. BMJ 2020; 369:m1858, p.2.

– British Geriatric Society (2020) Managing the COVID-19 pandemic in care homes: good practice guide. p.6. Updated 2nd June.

Our care homes strategy is based around some fundamental aspects of what we believe needs to happen to make care homes safer environments:

  1. Understanding that asymptomatic / pre-symptomatic transmission is a major contributor to the spread of Covid-19 in care homes, where the source of this transmission comes from outside (mostly via staff, but also visitors). Note that we have carried out an evidence review of asymptomatic and pre-symptomatic transmission, as well as an evidence review of airborne transmission and the effectiveness of masks.
  2. Clear delineation of zones of risk for the entire building, differentiating between contaminated & clean, which is reinforced through staff allocation & rotation.
  3. Hand disinfection for all points between risk zones (even where gloves remain on).

It also attempts to add some more pragmatic detail for certain elements – for example, how to practically re-purpose PPE using chlorine, and how to make chlorine dilutions.

The document is meant as a practical aid for care home managers to be able to implement effective infection control in their particular context. It is acknowledged that there will be a whole range of different types and set-ups of care home depending on the level of care required (e.g. nursing, care, sheltered housing), where each which will need a context-based response. However, the idea here is for managers to be able to use/adapt this document for their own context.

A webinar (courtesy of the AECB) was held on 23rd April explaining the rationale for this strategy:

There was also a second webinar (courtesy of the International Long-Term Care Policy Network) that was held on 25th May that focused on the issue of asymptomatic and pre-symptomatic transmission (at around 37 minutes into it):

There were also two BBC interviews on this subject on 21st April – these were on the BBC World Service and BBC News with Victoria Derbyshire. An additional interview was done on 6th May with BBC Radio Ulster (at around 1:08 into it).

More recently on 28th May, The Guardian ran a podcast looking into what went wrong in care homes, and our strategy was mentioned as being a key aspect of how one care home managed to sort out infection prevention and control (at 7 mins 55 secs into it).
