Mental health in Aged Care Homes

“nursing homes are the modern mental institutions for the elderly”1

“The prevalence of diagnosable psychiatric disorders has been estimated to be 80% or higher. The most common of these disorders are the dementias…” 1

The prevalence of mental health conditions in Australian long term aged care is estimated to be:

‘Good Practice’ to manage changed behaviourin dementia, anxiety and insomnia• Assess and manage other causes (e.g. pain,

infection, meds, environment, history……)

• Use non-drug measures first

Another way to manage these symptoms …..restraining physically

A physical restraint is anything near or on the body which restrictsmovement. Such as:

• Lap straps, belts, deep chairs, bean bags, vests or trays, which keepthe body immobile• Bed rails or belts, which keep people confined to their beds, and• Door alarms or locked doors which prevent people from walkingbeyond a set point

What is the problem with restraint?

From childhood on, one of the most important impulses isto maintain independence through movement.

As people age, their ability to move is compromised. For many people who live inaged care homes, it was thought for many years that using "restraints"– devicesthat prevent people from moving around — would ensure safety from falls, otherdangers and protect residents, other residents and staff.

“Evidence suggests that the prevalence of physical restraint in agedcare is between 12–49 per cent” (Alzheimer’s Australia 2014).1

Today, physical restraints are used much less frequently because studies haveshown they can be dangerous.

1. Alzheimer’s Australia.(2014). The use of restraints and psychotropic medications in people with dementia. Position paper 38

Adverse effects of physical restraintPossible physical effects of the inability to move freely include:

• Decreased bone/muscle strength • Decreased appetite and malnutrition• Dehydration• Pneumonia• Urinary tract infections• Constipation• Incontinence• Pressure sores and/or bruising• Death by asphyxiation

Possible mental or emotional effects of using restraints include:

• Agitation• Depression/withdrawal• Loss of dignity• Sleeping problems• Humiliation

What can be used instead?Things an aged care home can do instead of physical restraint include:

• Reducing the risk of falls and injury by using equipment such as low beds, non-slip mats and hip protectors

• Educating families and staff about behavioural and psychological symptoms• Increasing the safety of the home, such as secure environments to allow safe

wandering, or making sure the home is well lit• Increasing staff levels and direct care staff• Promoting light exercise and social activities• Taking care of needs such as poor eyesight and mental health, or problems such

as poor balance or unstable blood pressure.

Another way to manage these symptoms …..psychotropic medications

1. Farlex Partner Medical Dictionary. (2012). Retrieved June 6 2018 from https://medical-dictionary.thefreedictionary.com/psychotropic

Which are medications ‘capable of affecting the mind, emotions andbehaviour’ and are ‘intended to treat mental illness’.1

AntipsychoticsAnxiolyticsHypnoticsMood stabilisersAntidepressants

Cholinesterase inhibitors?Opioids?

Sedative: A medication that has a soothing, calming or tranquillizing effect

AntipsychoticsRisperidone, quetiapine, olanzapine,

haloperidol

benzodiazepines(hypnotics/anxiolytics)

diazepam, oxazepam, temazepam, lorazepam, nitazepam

sedating medications…

chemical restraint

Available at: https://www.legislation.gov.au/Details/F2019L00511/Explanatory%20Statement/Text 2. Center for Medicare Advocacy. Antipsychotic Drugs. Available at: http://www.waombudsman.org/files/2013/09/medicareadvocacy.org-Antipsychotic_Drugs.pdf

‘Chemical restraint is defined as restraint that is, or that involves, the use of medication for the purpose of influencing a person’s behaviour.

However, it does not include medication prescribed for the treatment of:

· a diagnosed mental disorder;· a physical illness;· a physical condition.1

In the U.S.A. the definition is: ‘any drug that is used for discipline or convenience’.2

Quality of Care Amendment (Minimising the Use of Restraints) Principles 2019.

A restraint-free environment is a basic human right for all consumersand restraint should not be implemented unless alternatives areexplored. Any decision to restrain a consumer carries significantethical and legal responsibilities.1

‘Good Practice’ to manage changed behaviourin dementia, anxiety and insomnia• Assess and manage other causes (e.g. pain, infection, meds)

• Use non-drug measures first

• Antipsychotics are indicated for changed behaviours if they cause significant distress, or pose a safety risk.

• Benzodiazepines are indicated short-term for severe anxiety (4 weeks) or severe insomnia (maximum of 2 weeks).

• Long term anxiety should be treated with antidepressants

• Non-pharmacological strategies should be continued

• When these drugs are prescribed, they should be monitored regularly for effectiveness and adverse effects, whilst using the lowest effective dose for the shortest period of time.

Prn psychotropic medication

An acronym from the Latin ‘pro re nata’: for ‘an occasion that has arisen’1

A prn prescription authorises administration of a medicine when needed, in theopinion of the nurse/staff administering medications. Dosing can be specified orentirely at the discretion of the person administering the medication.2

A case in point1

1. Coroners Court, Melbourne, Victoria: COR 2015 available from; 1527https://www.coronerscourt.vic.gov.au/sites/default/files/2019-02/MargaretBarton_152715.pdf

Mrs Margaret Barton (83yrs) medical history - Alzheimer’s disease, heart disease,osteopenia (multiple fractures). She was admitted for respite care late January 2015and was transferred to a permanent place in another home in late Feb 2015.- Respite home reported Mrs Barton as being ‘confused and paranoid’, with ‘significant

behavioural issues’ (anxious, wandering, verbally aggressive, resistive to care)- GP prescribed ‘prn’ oxazepam 7.5-15mg bd. Staff administered oxazepam at least daily

(15mg) for 16 days. GP then prescribed regular oxazepam 15mg tds & ceased ‘prn’ dosing.- Mrs B sustained 3 falls in the next week.- Transferred to the new permanent home 28th Feb, along with her medication chart.- Oxazepam 15mg tds but original ‘prn’ order was copied over. Additional doses were given

(combined dose was 90mg/day for 2 days).- Mrs B sustained 7 falls over the next week. Behaviours listed as ‘significant and persistent’.- By mid-March regular oxazepam was ceased, with ‘prn’ dosing of olanzapine, paracetamol,

oxycodone and oxazepam charted. All four medications were given twice daily.- Mrs B was admitted to hospital 20th March. Delirium was diagnosed. A CT scan identified 3

rib, 2 vertebral and a pelvic fracture.- Mrs B died 29th March.

- Post mortem revealed additional rib fractures and consequent pneumonia.

The RedUSe educational sessions

The educational sessions of RedUSe were primarily targeted at

nursing staff and carers and designed to:

• Provide education that challenged beliefs around psychotropic

effectiveness,

• Include information about their risks,

• Promote current guidelines

• Personalise and compare their own data

• Delivered by their own pharmacist at the

beginning of the project and then again at 3 months

Westbury, JL et al. “RedUSe: reducing antipsychotic and benzodiazepine prescribing in residential aged care facilities”, Medical Journal of Australia, 2018 208 (9) 398-403.

Beliefs of staff around psychotropic medication

Many staff believe that these medications are more beneficial than research suggests. They often stated that they felt psychotropics improved residents’ quality of life and that they were needed to ‘calm and comfort’ them.

“It may not be nice to medicate somebody but surely its far nicer to have them medicated and calm than distressed. On the whole they have a positive impact on their life.” EN

Aged care staff were often not aware of side effects associated with use, often attributing adverse effects of falling, drowsiness or movement effects as related to being old.

From Holland…Doctors, nurses, and family caregivers generally consider the benefits of antipsychotics to outweigh the risk of side effects. The main reasons to start therapy are agitation and aggression.

The estimated success rate in the discussed cases among doctors was 50%, nurses reported 53%, and relatives 55%. The most frequently expected adverse reactions were increased fall risk and sedation.1

Excuses not to RedUSe

30

1. Doctors write the scripts2. Nurses pressure us to3. Not enough staff4. Residents will all ‘go off’5. It’s only a small dose6. You have no idea what it’s like to work with them.7. Side effects are ‘overblown’8. If they make them die earlier, is that such a bad thing?
