Even though intensive home treatment is specifically designed to replace inpatient treatment ,there is almost no discussion -and certainly no research-about how exactly how it works in that regard. What functions of inpatient treatment does it replace? Which elements of intensive home treatment are a substitute for which elements of inpatient care? A group at London’s City University and the Royal College of Psychiatrists Research and Training Unit have developed a conceptual model of the aims and functions of acute inpatient psychiatry that I have found helpful in understanding how home treatment can substitute for them.
How is intensive home treatment an alternative to hospitalization?
David S. Heath FRCPC
To answer this question, we need to first understand psychiatric in-patient care: its key ingredients; how it functions to help patients; and what its effects are.
In spite of hospitalization being the predominant disposition for acutely and severely ill patients for almost 200 years- firstly in mental hospitals, and now mostly in general hospitals, there has been virtually no research on how it functions: “The literature demonstrates a striking lack of clarity behind the purpose of psychiatric admission and the way in which the process is conducted” ( Szmukler & Holloway); “ There is a sense that hospital care is a black box, with people being admitted and discharged but with little known about what happens to them while they are there”( Quirk& Lelliott).
Even its effectiveness in managing suicidal risk is in some doubt. A report in the UK (Appleby et al )which reviewed all patients in the UK who had been in contact with mental health services in the year before they committed suicide ,found that 16% of them were in hospital at the time- 21% of those on close observation; 24% committed suicide during the first three months after discharge-the peak occurring in the first 1-2 weeks. The Director of Mental Health Nursing at the English Department of Health writes: “It is also important to recognize that admission to hospital may not in any case have the effect of eliminating risk or even reducing risk. The experience of hospital admission can be distressing and stigmatising in itself and suicides are also still relatively common in in-patient settings. Risk may simply be delayed as suicides are also relatively common in the period following discharge from the ward.”(Brimblecombe)
Psychiatric in-patient treatment is probably unique among hospital services in that it does not provide any treatments that cannot be provided in the community; mental health assessment, psychotherapy, medication, electroconvulsive therapy, and clinical management are essentially the same, whether patients are living in the community or staying in a hospital. All the other hospital services-such as surgical, internal medicine and paediatrics provide clinical services that can only be provided in the hospital because of the need for such features as large complex machinery, immediate response of doctors and nurses, high tech monitoring and risky invasive procedures.
I have previously listed the 20 components of in-patient care, most of which can be provided to a significant degree, by intensive home treatment-sometimes coupled with a crisis residential service (Heath). Management activities such as containment ,close or constant observation and physical restraint were the only components that could not be provided in the community.
So, how can we understand how intensive home treatment substitutes for in-patient treatment?
A group at London’s City University and the Royal College of Psychiatrists’ Research and Training Unit have produced a model which attempts to analyze the functions and process of inpatient care. Although I have some disagreements with the model, it provides useful concepts which can aid in understanding how intensive home treatment can be an alternative to hospitalization. (Bowers, et al) The model consists of four elements of inpatient care-which differentiates it from community based services : legitimate authority, presence+, containment, treatment and management.
The first element –legitimate authority ( apart from the explicit authority of mental health legislation) is said to be derived from the social context of being a patient in a hospital staffed by doctors and nurses This “ bureaucratic , hierarchical , socially legitimated position of authority is coupled with 24 hours a day, 7 days a week staff presence” This merges with the second element ,presence + :the skills of a multidisciplinary team are concentrated in one area , maximising the expertise available to manage and treat the patient. This close proximity of staff and patients enables staff to develop positive and warm relationships with patients.
Containment is achieved by a combination of three features of hospitalization. The first is intrusion: the breaking of normal bounds of privacy, personal space or bodily integrity. Second is separation: from people or objects. Third is restriction: of freedom of physical movement.
Admission attempts to do all three. It submits patients to intrusive 24 hour supervision; separates them from general society of the ward and prevents them from possessing things they might use to harm themselves or others. It restricts their free movement.
The fourth element consists of a range of patient management tasks that include the provision of activities, channelling observations and reports and monitoring patient progress.
I contend that these four elements are not categorical, and only available in a hospital; they can be conceptualised as existing along a continuum and their functional equivalent is provided by intensive home treatment ,albeit to a lesser degree than inpatient care. Legitimate authority –in my experience- can exist by virtue of the daily-sometimes prolonged –presence of a team of mental health professionals in a patient’s home. In fact, there is a group of patients who explicitly reject the authority of hospitals and other institutions, and are more likely to be impressed by home visits from a psychiatrist and a nurse.
Presence + can be delivered by a combination of daily home visits, 24/7 immediate phone availability of a mental health professional, and the reassurance that someone can be at the home within 30 minutes. In addition there is the intentional, planned mobilization of empowered family members and other care givers. Of course, when these features are not sufficient, presence+ can be delivered by combining intensive home treatment with a crisis residence.
Even containment can exist along a spectrum. Harmful objects such as weapons and toxic substances can be removed from the home; patients can be closely supervised by family members who, in my experience, can be willing to go to great lengths to prevent their loved one from being admitted. Again, a crisis residence can provide a significant degree of containment.
Lastly, the element of management and treatment can –in many instances –be provided in the community.
In summary, whereas psychiatric hospitalization involves relocating patients to a hospital where they are placed in close proximity to a team of mental health professionals 24hours, 7 days a week, home treatment provides the functional equivalent of this, by relocating the staff to the patient’s home thus providing a degree of proximity by daily and at times lengthy visits, coupled with the assurance of rapid staff availability and 24/7 phone accessibility. Throw in mobilized and coached informal caregivers or-if needed a crisis residence, and one can understand how intensive home treatment can be a substitute for hospitalization. Just as the four elements of acute inpatient psychiatry are not discrete and categorical but can be seen as part of a continuum, so is the acuity of patients destined for hospitalization. There is a continuum of clinical and social features of patients which range from cases that almost –but not quite, could be handled with some extra outpatient visits and some groups in a day hospital, to wildly aggressive and psychotic individuals who spend their first hours in the hospital in restraints.
Intensive home treatment providing the functional equivalent of the four elements of acute inpatient psychiatry is appropriate for roughly 40% of patients who would otherwise need admission. Intensive home treatment-even when combined with a crisis residence will not work for the other 60% of patients because of a combination of many factors. These include: patients unable or unwilling to cooperate and be engaged ; behaviours that are highly risky or are highly disturbing; high suicide risk; active substance abuse; poor housing, and lack of social support or even toxic social circumstances. However, these limiting clinical features can be reduced, even after a short time in hospital, sufficiently to allow early discharge of some patients to intensive home treatment.
