Care of the Elderly Flashcards

1
Q

define frailty

A

state of increased vulnerability resulting from ageing associated decline in reserve and function across multiple physiological systems such that ability to cope with everyday or acute stressors is compromised

key bits is they have a poor functional reserve, so they’re really vulnerable to decompensation when faced with illness, drug side-effects or metabolic disturbances

Q

what are some common co-morbidities seen in the elderly?

A
linked - lung cancer, COPD, peripheral vascular disease (smoking causes all)
unlinked:
- diabetes
- dementia
- myeloma

PNEUMONIA - often seen on top of all of these!

Q

what is acopia?

A

term for “social admission” - negative connotations - DON’T use.
used to describe pts unable to cope with ADLs.

beware serious underlying pathologies that can easily be missed.

Q

what is deconditioning?

A

occurs after a patient has been bedbound for days/weeks when admitted to hospital
they’re confused.
poor nutritional state (often present even prior to admission), made worse by acute illness.
can’t walk, falls, can’t look after themselves.
need a lot more than just meds!

Q

what is involved in a comprehensive geriatric assessment?

A

it’s a multidimensional, multidisciplinary diagnostic process
determines frail older person’s medical, psychological and functional capacity.
tries to develop coordinated, integrated plan for treatment and long term follow up.

Q

what four things do you assess when assessing capacity?

A

Understand the information relevant to the decision
Retain the information
Weigh up the information
Communicate the decision

91
Q

what are the five key aspects of the MCA?

A

1) Assume capacity – person assumed to have capacity until proven otherwise
2) Maximise decision-making capacity – all practical support to help a person make a decision should be given
3) Freedom to make seemingly unwise decisions – an apparently unwise decision in itself does not prove incapacity
4) Best interests – all decisions taken on behalf of the person must be in their best interests
5) Least restrictive option – when making a decision on another person’s behalf, the alternative that achieves the necessary goal and interferes the least with the person’s rights and freedom of action must be chosen.

92
Q

explain what should be considered when making a best interests decision

A
  • Whether the person is likely to regain capacity and can the decision wait
  • How to encourage and optimise the participation of the person in the decision
  • The past and present wishes, feelings, beliefs, values of the person and any other relevant factors
  • Views of other relevant people
93
Q

what do advanced directions allow?

A

Allow people who understand the implications of their choices to state their treatment wishes in advance.
They can be used to:
- Authorise or request specific procedures
- Refuse treatment in a predefined future situation (advance directive)

94
Q

when is an advanced refusal of treatment legally binding?

A

if:

1) The person is an adult, and
2) Was competent and fully informed when making the decision, and
3) The decision is clearly applicable to current circumstances, and
4) There is no reason to believe that they have since changed their mind

95
Q

when are advance requests for treatment legally binding?

A

they aren’t! should be considered when assessing best interests, but legally a patient may not demand specific treatment.

there is a duty to take reasonable steps e.g. artificial nutrition and hydration to keep the person alive if that is patient’s known wish

96
Q

explain what a lasting power of attorney is

A

“A document which a person can nominate someone else to make certain decision on their behalf (for example on finances, health and personal welfare) when they are unable to do so themselves”.
To be valid, it needs to be registered with the Office of the Public Guardian

97
Q

what is an IMCA?

A

Independent mental capacity advocate (IMCA)

  • Commissioned from independent organisations by the NHS and local authorities to ensure that MCA is being followed
  • Role of IMCA: support and represent people who lack capacity and they do not have anyone else to represent them in decisions about changes in long-term accommodation or serious medical treatment. They can also be present for decisions regarding care reviews or adult protection.
98
Q

when is a DoLS required?

A
  • Mental Capacity Act allows restraint and restrictions to be used – but only if they are in a person’s best interests.
  • Extra safeguards are needed if the restrictions and restraint used will deprive a person of their liberty. These are called the Deprivation of Liberty Safeguards.
  • DoL = any time a patient is subject to continuous supervision or control, and/or is not free to leave the care home/hospital - and lacks capacity to consent to any of this.
99
Q

what is the process for getting a DoLS?

A
  • care homes or hospitals must ask local authority if they can deprive a person of their liberty. This is called requesting a standard authorisation.
  • There are six assessments which have to take place before a standard authorisation can be given.
  • If a standard authorisation is given, one key safeguard is that the person has someone appointed with legal powers to represent them. This is called the relevant person’s representative and will usually be a family member or friend, but might be an IMCA.
100
Q

what conditions need to be met before a standard authorisation (under DoLS) can be granted?

A
  • person is 18 or over (different safeguards apply for children).
  • person is suffering from a mental disorder.
  • person lacks capacity to decide for themselves about the restrictions which are proposed so they can receive the necessary care and treatment.
  • restrictions would deprive the person of their liberty.
  • proposed restrictions would be in the person’s best interests.
  • should the person instead be considered for detention under the Mental Health Act?
  • there is no valid advance decision to refuse treatment or support that would be overridden by any DoLS process.

if any of these not met, authorisation not granted - so care home/hospital has to adjust care plan to be less restrictive.

101
Q

who conducts a DoLS assessment?

A

two independent professionals - one a mental health assessor, one a best interests assessor - need to have had specific training.

nearest relative or IMCA also consulted.

102
Q

what are the six assessments that are done as part of DoLS assessment?

A

1) age assessment (must be <18yrs)
2) no refusals assessment - would proposed care go against any advanced refusals in place or decision of someone with LPA?
3) mental capacity assessment - as per MCA to assess whether capacity to decide on these deprivations of liberty
4) mental health assessment - can only be authorised if they have a ‘mental disorder’ as defined in MHA
5) eligibility assessment - not eligible for DoLS if under MHA sections
6) best interests assessment - performed by best interests assessor, taking into account views of close family/relatives, anyone with LPA, IMCA etc

103
Q

in a DoLS assessment, who can act as best interests assessor?

A

an approved mental health professional, social worker, nurse, occupational therapist or psychologist, with the required training and experience.
can be employed by the supervisory body or the managing authority, but must not be involved in decisions about your care or treatment.

110
Q

when might you refer a falls patient to a geriatrician specialising in falls?

A
