Caring for someone with fluctuating or complex needs

Conditions that vary day to day, or that involve several overlapping health and social needs, bring particular planning and communication challenges for carers.

Some conditions, such as many mental health conditions, fatigue-related conditions and some neurological and pain conditions, can vary a great deal from day to day. This can make planning care, work and benefits claims harder.

Describing fluctuating needs

  • When applying for benefits or care assessments, describe both good and bad days, and how often bad days happen, rather than just an average.
  • Say if the person cannot do something reliably, safely, repeatedly and in a reasonable time, since this is the test used for many disability benefits.
  • Keep a simple diary over a few weeks if possible, to show patterns.

Coordinating multiple services

Where someone has several conditions, care can involve multiple hospital teams, GPs, social care and sometimes mental health services, and it often falls to carers to join the dots.

  • Ask if there is a named care coordinator or key worker who can act as a single point of contact.
  • Keep an up-to-date list of medications, diagnoses, and contacts for each professional involved.
  • Ask services to write to each other, and to you, so information is not lost between appointments.

Checklist

  • Keep a short diary of good and bad days to support assessments and reviews.
  • Ask about a care coordinator or key worker if several services are involved.
  • Keep an up-to-date one-page summary of conditions, medications and emergency contacts.
  • Ask each service to share letters and updates with the others, with consent.
  • Review care and support plans regularly, not just when things go wrong.
  • Ask about advance care planning if the condition is progressive.

Common mistakes

  • Describing only an average or a 'good day' when asked about needs, which can understate the level of support required.
  • Assuming one professional is keeping the whole picture in view when no one has that role.
  • Not updating care plans after a change in medication or diagnosis.
  • Leaving planning until a crisis, rather than reviewing it while things are stable.
