Section 25 Emergency Medicine and the Law
25.1 Mental health and the law: the Australasian and UK perspectives
Introduction
In the UK and Australasia, doctors in general are empowered by legislation to detain a mentally ill person who is in need of treatment. Mental illness, particularly its manifestation as self-harm, is a common ED presentation (in the UK, making up around 1–2% of new patient attendances, and up to 5% of attendances in Australasia), and emergency physicians require not only the clinical skills to distinguish between those who require psychiatric or medical intervention, but also a sound working knowledge of the mental health legislation and services relevant to the state where they practise. This ensures that patients with psychiatric illness are managed in the most appropriate way, with optimal utilization of mental health resources and with the best interests and rights of the patient and the community taken into consideration.
Whilst there are variations in mental health legislation between the UK, Australia and New Zealand, all legislation recognizes fundamental common principles that respect individual autonomy and employ least restrictive management practices. The World Health Organisation (WHO) advises 10 basic principles of mental healthcare law, including enshrining geographical, cultural and economic equity of access to mental health care, acceptable standards of clinical assessment, facilitating self-determination, minimizing restrictive treatment and enshrining regular and impartial decision-making and review of care.1 These themes are all present in Australasian and UK law, and awareness of such principles aids the clinician in delivering humane and ethical treatment for mentally unwell patients who seek emergency care.
Variations in practice
Mental health legislation in England and Wales
Mental Health Act
Detention of patients with mental illness
Section 2 of the Mental Health Act facilitates compulsory admission to hospital for assessment and treatment for up to 28 days. The application is usually made by an approved social worker or the patient’s nearest relative and requires two medical recommendations, usually from the patient’s general practitioner and the duty senior psychiatrist (who is approved under Section 12 of the Mental Health Act). In the ED, the responsibility for coordinating the procedure often lies with the emergency physician.
Section 3 of the Mental Health Act covers compulsory admission for treatment. Once again, recommendations must be made by two doctors, one of whom is usually the general practitioner and the other a psychiatrist approved under Section 12 of the Act. The application is usually made by an approved social worker or the patient’s nearest relative. Detention is for up to 6 months but can be renewed.
Section 4 of the Mental Health Act covers emergency admission for assessment and attempts to avoid delay in emergency situations when obtaining a second recommendation could be dangerous. It requires the recommendation of only one doctor, who may be any registered medical practitioner who must have seen the patient within the previous 24 h. The order lasts for 72 h. Application can be made by the patient’s nearest relative or an approved social worker. In practice, the application of Section 4 of the Mental Health Act rarely happens. Usually Section 2 or 3 is the preferred option.
Section 5 (2) – doctors holding power and Section 5 (4) – nurses holding power of the Act allow the detention of patients who are already admitted to hospital until a more formal Mental Health Act assessment can take place. Unfortunately, presence in the ED is not considered to constitute admission to hospital, and this section is, therefore, not applicable to the ED.
A new draft Mental Health Bill published in 2002 was opposed by professional and patient groups alike. It aimed to introduce a new legal framework for the compulsory treatment of people with mental disorders in hospitals and the community. The new procedure involved a single pathway in three stages: a preliminary examination, a period of formal assessment lasting up to 28 days and treatment under a Mental Health Act order. In order for the compulsory process to be used, four conditions needed to be satisfied: the patient must have a mental disorder, the disorder must warrant medical treatment, treatment must be necessary for the health and safety of the patient or others, and an appropriate treatment for the disorder must be available. The draft Bill made provision for treatment without consent as it is justified under the European Convention on Human Rights Article 8 (2) in the interests of public safety or to protect health or moral standards.
Mental Capacity Act
Emergency treatment
Treatment can be given to patients who lack capacity but several factors need to be considered:
Use of sedation or physical restraint
This is covered in detail elsewhere (Chapters 20.6 and 21.5). From the perspective of the mental health legislation, there are occasions where physical or pharmacological restraint is needed. Sedation or restraint must be the minimum that is necessary to prevent the patient from self-harming or harming others. Generally, a patient committed involuntarily is subject to treatment necessary for their care and control, and this may reasonably include the administration of sedative or antipsychotic medication as emergency treatment. Transporting these patients to a mental health service should be done by suitably trained medical or ambulance staff, and not delegated to police officers or other persons acting alone.
Mental health legislation in Australasia
In Australia mental health legislation is a state jurisdiction, and among the various states and territories there is considerable variation in the scope of mental health acts, and between definitions and applications of the various sections. Since the National Mental Health Strategy in 1992, there has been an effort in Australia to adopt a consistent approach between jurisdictions, with an emphasis on ensuring legislated review mechanisms and a broad spectrum of treatment modalities.2 Nevertheless, key differences apply between mental health acts and therefore specific issues should be referred to the Act relevant to the emergency physician’s practice location.
The Australian and New Zealand mental health acts referred to in this chapter are the following:
Definition of mentally ill or mental illness
South Australia
In the South Australian Act mental illness means any illness or disorder of the mind.
Indigenous and cultural acknowledgement
Cultural differences in the understanding and experiences of mental illness can impact greatly on the ability to provide adequate care. Whilst there are some cursory references to acknowledging special cultural and linguistic needs when interpreting the various mental health acts, only the Northern Territory in Australia and the New Zealand Mental Health Acts make specific mention of indigenous people, who are known to be a particularly vulnerable group.3
Involuntary admission
New South Wales
For a mentally ill patient the certificate is valid for 5 days from the time of writing, whereas for a mentally disordered patient the certificate is valid for 1 day. Mentally disordered patients cannot be detained on the grounds of being mentally disordered on more than three occasions in any 1 month.
Tasmania
In Tasmania, an application for involuntary admission of a person may be made by close relative or guardians, or an ‘authorized officer’. A medical practitioner must then assess the person and, if satisfied that the criteria are met, make an order for admission and detention as an involuntary patient in an approved hospital. This initial order is valid for 72 h and gives authority for the patient to be taken to the hospital and detained, whereupon a psychiatric assessment must be carried out within 24 h and the initial order confirmed or discharged. A further order for the continuing detention of a person as an involuntary patient can be made if the appropriate criteria are met and after two doctors (at least one a psychiatrist and neither having written the initial order) have examined the patient. A continuing care order can be valid for up to 6 months.
Use of sedation or physical restraint
Queensland requires that restraint used for the protection of the patient or others can only be done on an ‘order’ but is permissible for the purposes of treatment if it is clinically appropriate. Tasmania permits its use, on the approval of the responsible medical officer, for the medical treatment or protection of the patient, other persons or property. Victoria permits the restraint of involuntary patients for the purposes of medical treatment and the prevention of injury or persistent property destruction. Victoria also allows the use of restraint by ambulance officers, police or doctors in order to safely transport the patient to a mental health service, but this must be documented in the recommendation schedule.
Prisoners with mental illness
The New Zealand Act states that prisoners with mental illness who require acute care can be transferred to a general hospital for involuntary psychiatric treatment, if the prison is unable to provide that care. Australian Acts in New South Wales, the Northern Territory and Victoria all include similar specific provisions for mentally ill prisoners to be able to access involuntary care in public hospitals if needed. The Victorian Act is most detailed in this matter, although in practice rarely relies on public hospitals due to the development of a stand alone forensic psychiatric hospital. Both Queensland and Western Australia enshrine the same principle of allowing prisoners access to general psychiatric treatment, although their legislation is less specific, whilst the Tasmanian, South Australian and ACT Acts do not mention prisoners at all. In all jurisdictions, there is significant overlap with other laws such as Crimes and Prisons Acts, which also mention health needs of prisoners.
