Foreword

The Department of Human Services commissioned the Emergency Medicine Unit at the Royal Melbourne Hospital to conduct this research to gain an increased understanding of the nature of mental health presentations to emergency departments and why emergency departments are being used as a point of care for people experiencing mental health problems. The research builds on the work of the Hospital Admission Risk Program’s (HARP) Mental Health Working Party. The research reference group contributed to the research design and analysis and endorses the report. A major fi nding of the research is that many people presenting to emergency departments are already receiving care from public mental health services or have done so in the recent past. The research found more than one in ten presentations were related to the fact that no acute mental health bed was immediately available at a time when the person was assessed as being in need of an admission to hospital. The research reference group has considered the research. The fi ndings indicate the mental health service system is struggling at a time of unprecedented demand for mental health care and look at how this demand is being experienced at the emergency department. While emergency departments are one of the potential entry points into public mental health care, their role should be to assist people with the most urgent mental health diffi culties. It is important that consumers whose treatment needs can be more appropriately addressed by other elements of the service system are supported to access these alternatives. The fi ndings of the research have been presented at a forum where people working in mental health services, emergency departments, police and ambulance services, as well as consumers and department staff, had the opportunity to discuss the research and look at ways of improving care for consumers. The forum discussion is summarised at the end of the report. The reference group sees a need for additional resources for mental health, including beds and community- based care and better information for consumers and families to obtain help when needed. The examination of models of care within both mental health services and the emergency departments is also important work to be undertaken. The principle of a consumer-focused continuum of care should inform planning resulting from this report; however, the operationalisation of this principle will require that all parts of the service system contribute to meeting the needs of consumers and their families in a comprehensive manner and with the collaboration of all involved.

Non-government psychiatric disability and rehabilitation support services in each area also provide a range of non-clinical outreach support, day programs and residential facilities.

These departments saw approximately 180,000 patients in 2001–02. Data collection was planned for fi ve months. The proportion of patients who met the inclusion criteria at these hospitals had previously been found to be 6.8 per cent (5.6 per cent with defi ned mental health diagnosis and 1.2 per cent with intentional self-harm).3 Approximately 1 per cent of the inclusive group was identifi ed as intoxication only. Thus, the predicted sample was 4,350 subjects. Mental health presentations to the emergency department 10

Because ‘did not wait’ indicates no clinician assessed the patient, it was often not possible to provide an ICD-10 code. Given this study population was selected by ICD-10 code, ‘did not wait’ will tend to be underrepresented. 6. ‘Time to be seen by clinician’: This was usually the ED medical staff; however, due to co-location of mental health services for at least part of the time at all fi ve sites, the fi rst clinician may have been from mental health services. Often, in those cases, the patient was not seen by medical staff. 7. ‘Delay from referral to review by mental health staff’: This indicates the time from referral to being seen by any member of mental health services, including Enhanced Crisis Assessment and Treatment Team clinicians, psychiatric registrars or consultants. 8. Several variables returned very poor data as a result of incomplete recordkeeping and were not reported; for example, past forensic history.

Demographics For all mental health patients presenting to the ED, 1,909 (51.5 per cent) were male. There was minimal variation across sites. Over the same period, 54.4 per cent of all non-mental health presentations were male. Mental health patients are typically in their early thirties. There were only 78 patients (2.1 per cent) under the age of 16, although the Alfred Hospital and Royal Melbourne Hospital do not see paediatric patients. As anticipated, the mental health patients were younger than the non-mental health patients presenting to the same EDs.

Country of birth A minority (12.7 per cent) of the mental health patients were born overseas. The countries of origin are presented in Appendix C. There are at least 58 nations represented. The proportions appear to represent the general ethnic mix in the community. It is possible that some of those identifi ed as born in Australia were actually born overseas.

Ambulance referrals

Arrival by ambulance Arrival by ambulance includes arrivals by the Metropolitan Ambulance Service for Greater Melbourne and Rural Ambulance Victoria. Forty per cent of mental health presentations to the ED were by ambulance— a signifi cant portion of the caseload. For non-mental health patients, 29.5 per cent arrived in the ED by ambulance. Clearly factors associated with ambulance call-out and transports are important and warrant further investigation. Geelong had a noticeably lower proportion of ambulance presentations for this population of patients.

Referral to ambulance A substantial minority of ambulance call-outs were by groups (for example, police and mental health services) that might have access to other services besides the ED. Alternative models for mental health management might consider how these groups would access those other services.

Other referral sources

Arrived with police Six hundred and fi fty-one of the mental health presentations (17.6 per cent) arrived in the ED with the police. Only 39 (6.2 per cent) of these were referred to the police by the ambulance.

Arrived with the Crisis Assessment and Treatment Team There were 207 presentations (5.6 per cent) who arrived with the Crisis Assessment and Treatment Team or another community mental health service. The majority (71.7 per cent) of these were admitted to a psychiatric ward.

Arrived with family There were 787 (21.2 per cent) presentations in the care of family and 845 (22.8 per cent) where a specifi c carer issue was a signifi cant factor for the presentation. There was considerable overlap between these groups.

Referred by general practitioner Two hundred and thirty-four of the mental health presentations (6.3 per cent) had been referred in by their general practitioner or other community health service. The disposition of this group is not signifi cantly different from that of all mental health patients. It is possible that some of these patients could have been seen directly by mental health services rather than referred via the ED.

Emergency presentation

Day of arrival The mental health presentations occurred consistently across the week, with an unexpected peak mid-week and a nadir towards the weekend. The pattern was nearly identical across all fi ve sites.

Figure 3: Day of presentation to the ED by mental health patients

Time of arrival The majority of presentations occurred outside normal working hours, particularly in the evening, and continued throughout the night. This is important for resourcing mental health services in the ED and increases the diffi culty of sourcing alternative services.

Figure 4: Time of arrival in the ED by mental health patients

Mental health presentations to the emergency department 19

There was a very similar pattern in the arrival by day of week for mental health patients compared with non-mental health.

Figure 5: Day of presentation to the ED for mental health patients compared with non-mental health patients (per cent)

Compared with non-mental health patients, those with mental health issues presented after hours, especially between 20:00 hours and 04:00 hours.

Figure 6: Time of arrival in the ED compared with non-mental health patients (per cent)

The pattern of presentations throughout the day was consistent across the fi ve sites.

Figure 7: Time of arrival in the ED by mental health patients, by site

Services sought prior to the ED While 51 per cent of mental health presentations sought no help prior to arrival in the ED, an average of 41 per cent did (21 per cent to 91 per cent across sites). This suggests the ED is not the primary point of care for many mental health patients, but they end up using it anyway.

Note: MH = mental health Mental health presentations to the emergency department 21

There was considerable variation across sites regarding services sought prior to the ED. The variation mostly related to seeking support from a general practitioner rather than from community mental health services, especially at Maroondah Hospital. These data do not indicate that the patient successfully contacted a service, only that they indicated an attempt had been made. The variation across sites may refl ect real differences. Alternatively, it may refl ect the way this information is sought or recorded in different EDs.

Figure 8: Services sought prior to the ED (per cent), by site

Note: Comm = community; MH = mental health

Mental health provider unavailable From the medical record, there were 217 cases (5.9 per cent) where the mental health provider was reported as unavailable. This may be a signifi cant underrepresentation, although only 60 records (1.6 per cent) were left blank. The remainder—92.6 per cent—did not indicate that the mental health provider was unavailable.

Triage category There were very few mental health presentations requiring immediate assessment (triage category 1). Similarly, only 279 patients (7.5 per cent) were designated as non-urgent (triage category 5). Compared with the non-mental health ED population, there were more triage category 3 and fewer triage category 4 patients in the mental health ED population.

Note: non-MH = non-mental health Mental health presentations to the emergency department 22

Across the sites, there was an increased proportion of triage category 2 mental health patients at Royal Melbourne Hospital, and Dandenong ED had fewer triage category 3 and more triage category 4 mental health patients. Differences are likely to be due to either the acuity of the patient population at each site or triage practice.

Figure 9: Triage category (per cent), by site

Time to see clinician The median time to see a clinician, usually a doctor, was only 26 minutes, with 75 per cent of all mental health presentations being seen in less than one hour. Few waited more than four hours to be seen. This short waiting time might point to a small number of ‘did not wait’ patients among the mental health patients. It is also important in identifying the relatively small contribution of waiting time to total ED length of stay.

Note: IQR = inter-quartile range Mental health presentations to the emergency department 23

There was some variation across sites in waiting time to be seen by clinicians. This may refl ect differing models of care used for mental health patients, especially at Geelong Hospital where all mental health patients are seen immediately by mental health services unless there is an urgent medical problem.

Figure 10: Time to see clinician, by site

Toxicology There were 1,218 mental health patients (33 per cent) who were intoxicated on arrival in the ED. The intoxicants were a representative list of drugs of recreational use and abuse as well as common choices for self-harm. Typical ED care of mental health patients precludes the mental health assessment when the patient is intoxicated. Mental health wards do not readily accept patients while intoxicated and medical wards may not be able to provide a secure environment for mental health patients at risk. The ED currently provides a management setting for patients with a combination of mental health issues and intoxication. Decreasing the total ED length of stay will require alternative models of care for the intoxicated mental health patient.

Patients referred to mental health services There is a clear disparity in the proportion of referrals to mental health services at Royal Melbourne Hospital and, to a lesser extent, Maroondah Hospital. Royal Melbourne Hospital has a 24-hour ED-based Enhanced Crisis Assessment and Treatment Team, so a lower referral rate is unlikely to be due to availability of mental health services. The lower referral rate may represent a lower acuity of mental health issues or greater confi dence in dealing with those issues by the ED medical staff. It would be important to know the outcomes for these patients in terms of re-presentation, total ED length of stay or organised follow-up, given that a mental health consultation has not occurred. This is a topic for further research.

Delay from referral to review by mental health services Seventy-fi ve per cent of patients were seen by psychiatry staff within 85 minutes of referral; however, there was a small but signifi cant number of long delays. These were mostly associated with intoxicated patients and it is assumed that despite an early referral the consultation was delayed by the patient’s clinical state. Dandenong Hospital had a longer median delay to review and it is noted that this site does not have in-house mental health cover overnight but relies on call-back of the psychiatry registrar. For delays over six hours, the proportion with documented intoxication rose to 66 per cent, and 80 per cent of these mental health patients had toxicology related diagnoses. For this group, the proportion appearing after hours also increased, although there were no obvious increases on the weekend.

Requiring a special (one-on-one nursing) For all mental health patients, there was a need to special 359 (9.7 per cent) with one-on-one nursing. This is an important resource issue for EDs. EDs are currently not designed as secure environments for mental health patients at risk of harm or absconding. Future designs may need to accommodate the longer duration of stay in the ED for these patients unless alternative strategies can be developed. Mental health presentations to the emergency department 26

Total length of stay in ED While the median time spent in the ED is approximately four hours, 20.5 per cent of patients spend more than 12 hours. In this sample, 5.9 per cent stayed more than 24 hours and the maximum time spent on an ED trolley was fi ve days. The Alfred Hospital had the best performance, with no patient staying more than 24 hours. Conversely, Dandenong Hospital had nearly 50 per cent of all mental health patients who stayed more than 24 hours. Given the sites had similar short waiting times to be seen by a clinician, this is unlikely to have affected total length of stay. Dandenong did have a longer delay to mental health review after referral, but the increase in median time was 20 minutes and unlikely to have signifi cantly affected total length of stay. The probable cause for the prolonged stay was access to beds. Even allowing for the current model of care which keeps mental health patients in the ED until their intoxication has resolved, a stay of more than 24 hours is otherwise diffi cult to explain and total ED length of stay of several days is unlikely to be due to ongoing ED management. Alfred and Geelong Hospitals had few patients staying more than 24 hours, but still had 10 per cent at 12 hours. This is likely to be the result of either mental health patients with intoxication who required prolonged ED care or diffi culty accessing a mental health bed. Alternative models should be sought to allow co-management of mental health issues and intoxication in an environment other than the ED. Those mental health patients staying more than 12 hours were more likely to be admitted and more likely to be involuntary; this was even more pronounced at 24 hours. For the population of mental health patients who stayed more than 24 hours in the ED, only 25.5 per cent were intoxicated on arrival and the ICD-10 diagnoses of depression, psychosis and schizophrenia described 53.6 per cent of the group.

ED investigations ED investigations are essentially routine blood tests ( full blood count and urinalysis & electrolytes) and screening for intoxication (alcohol) or paracetamol overdose. Mental health patients uncommonly had radiological testing or urine drug screens. Of note, 60 per cent of all mental health patients had no investigation done in the ED at all. There were 2,482 patients who were not intoxicated on arrival; 1,770 (71.3 per cent) of this group had no investigations in the ED. Mental health patients, especially those without intoxication, usually do not have investigations performed in the ED.

ED restraint A security code for an unarmed threat (Code Grey) was called on 303 patients (8.2 per cent). Physical restraint was required for 151 patients (4.1 per cent) and chemical restraint for 394 patients (10.6 per cent). The median time that physical restraint was applied was 180 minutes (inter-quartile range: 60–60), with a maximum time of 2,340 minutes (39 hours). There were 48 patients (1.3 per cent) who were restrained for more than four hours. Chemical restraint was often done using a combination of drugs. Diazepam and Midazolam were most likely to be used, followed by Droperidol. The newer atypical neuroleptics are also starting to be used for chemical restraint in the ED, with Olanzapine the fourth most likely drug to be chosen. Haloperidol had previously been shown to be commonly used for chemical restraint,12 but is currently employed less frequently.

Note: Multiple drugs were given in some cases. % of CR = percentage of chemically restrained patients (394) Mental health patients who were restrained in the ED were seen quickly on arrival (median wait of 17 minutes (IQR: 6–46)) and had short delays to review by mental health services (median delay of 30 minutes (IQR: 10– 60)). They were more likely to be admitted (62.6 per cent) and held involuntarily (45.8 per cent). Their total ED length of stay was a median of eight hours and 46 minutes, with 210 patients (40.2 per cent) staying more than 12 hours and 75 patients (14.4 per cent) staying more than 24 hours. Mental health presentations to the emergency department 29

Legal status on arrival Most mental health patients were voluntary when they arrived in the ED; however, there was a small number (3.6 per cent) of mental health patients with revoked community treatment orders or under s. 12 of the Mental Health Act 1986 (see Appendix D). These patients must, by defi nition, be actively under the care of mental health services and should have been admitted directly into hospital to an appropriate ward. It should not be necessary for these patients to stay in the ED. The median stay in the ED for these patients was only four hours, but 47 patients (35.3 per cent) stayed more than 12 hours and 17 patients (12.8 per cent) stayed more than 24 hours. The Alfred Hospital and Royal Melbourne Hospital have a much higher number of patients brought in by the police under s. 10 of the Mental Health Act than the other hospitals. This is not refl ected in the numbers of all mental health patients brought in by the police (see page 36) and is indicative of either local police practice or documentation of s. 10 at those sites.

Legal status on departure All sites had approximately the same proportion of involuntary mental health patients at discharge (approximately 15 per cent). The exception is Geelong Hospital, which had only 61 patients (8.7 per cent). Geelong also had the lowest number arriving in the ED under s. 10 of the Mental Health Act and no patients who were under s. 9 of the Mental Health Act (see Appendix D). This may refl ect the different model of practice that is employed at Geelong or a different patient population with lower acuity of mental health issues.

Disposition There was a 30.3 per cent admission rate to hospital for patients with mental health issues presenting to the ED: 6.6 per cent were admitted to a general ward (including short stay unit) and 23.7 per cent were admitted to a psychiatric ward (either onsite or transferred to ‘other area mental health’). Of those requiring psychiatric admission (878 patients), 191 (21.8 per cent) required transfer to another facility. Some patients (6.1 per cent) either did not wait for treatment or absconded after it had commenced. By comparison, for non-mental health patients, 61.7 per cent were discharged to their usual residence, 24.7 per cent were admitted to a ward, 3.6 per cent were admitted to a short stay unit, 4.7 per cent did not wait to be seen, and 0.8 per cent absconded after treatment commenced (Victorian Emergency Minimum Dataset). There was variation in the proportion of mental health patients sent home from the ED across sites, with Alfred and Geelong Hospitals sending home about 50 per cent and the other sites about 63 per cent. Mental health patients in the Alfred and Geelong Hospitals had shorter total ED length of stay and no patient stayed more than 40 hours in total. The differences in disposition rates may indicate that longer ED length of stay raises the threshold for admission (that is, access block to beds encourages clinicians to discharge patients home). If this is the case, the outcomes of patients sent home should be independently assessed.

Table 27 is summarised to show the main disposition categories. The Alfred and Geelong Hospitals had the shortest total ED length of stay and were admitting more mental health patients to medical wards, either general wards or the short stay unit. Dandenong and Maroondah admitted almost no patients to medical wards. Admitting mental health patients to non-mental health wards appears to be inversely related to total ED length of stay.

Note: In the records reviewed over the study period, there were no deaths of mental health patients in the ED. Dandenong and Maroondah Hospitals had a high proportion of mental health patients being admitted via the ED. These sites also had the majority of mental health patients arriving in the ED only because no mental health bed was available (see page 34).

Ancillary services Only 296 mental health patients received any specifi c ancillary service. This is despite previous work which showed that mental health patients in the ED have low linkage into community services. If that is correct, these fi gures suggest that few patients are receiving assistance from the ED in accessing those services.

Table 28: Ancillary services for mental health patients in the ED

Service Number % Interpreter 33 0.9 Care coordinator 141 3.8 Social worker 135 3.6 Financial aid 28 0.8 Crisis accommodation 76 2.1

Note: Some mental health patients received more than one service. Frequent users of the ED—those with at least six presentations in the last 12 months—are less likely to receive ancillary services. This may refl ect the fact they have already been linked in to community resources. It may also refl ect ‘fatigue’ or ‘familiarity’ in clinicians when frequently dealing with particular patients, which might cause them not to consider extra resources.

Diagnosis The ICD-10 code is the fi nal diagnostic category given to each presentation. The top 12 codes refl ect the expected mix of mental health illness and intoxication for patients presenting to the ED. There is only one code per presentation given in the ED and this code may be unable to refl ect the combination of factors that lead to ED mental health presentations. In addition, a number of different codes can be employed to describe similar presentations (for example, attempted suicide by overdose could be coded as depression, poisoning or suicidal).

In addition to the ICD-10 code, the study identifi ed the cause for mental health presentation to the ED. Multiple issues were recorded if present. The issues one would expect to be affecting mental health patients in an ED topped the list: depression, self-harm and psychosis. Issues that would not be expected to involve the ED, such as accommodation and eating disorders, were at the bottom of the list. In general, the issues at presentation are signifi cant mental health disorders and intoxication or drug overdose.

Relevant past history For all mental health patients presenting to the ED, 1,350 (36.4 per cent) were current, active mental health clients. There were 843 patients (22.8 per cent) for whom this was the fi rst contact with mental health services. The remainder had previously been in contact with mental health services, but were not currently being managed by them.

Previous psychiatric admissions There were 957 patients (25.9 per cent) who had been admitted to a psychiatric ward in the previous 12 months. Of these, 399 (41.7 per cent) were admitted at the current presentation, 39 (4.1 per cent) ‘did not wait’ and 39 (4.1 per cent) absconded. A further 16 per cent of all mental health presentations had had an admission more than 12 months ago.

ED presentations in the previous 12 months More than 50 per cent of mental health patients had been in the ED in the previous 12 months and 9 per cent had at least six presentations. These fi gures indicate only the presentations at the same institution and therefore underrepresent the rate at which mental health patients are accessing health care across the emergency system.

Arrival with police Six hundred and fi fty–one of the mental health presentations (17.6 per cent) arrived in the ED with the police. Only 39 (6 per cent) of these were referred to the police by the ambulance.

Time spent in the ED was comparable with that for all mental health presentations; however, 141 patients (21.7 per cent) required one-on-one nursing or ‘specialing’. This is a signifi cant resource issue for EDs.

A small number (17 patients (2.6 per cent)) left in police custody and 17 (2.6 per cent) were admitted to a general ward (including a short stay unit). However, 251 patients (38.5 per cent) were admitted to a psychiatric ward (45.1 per cent if arrival under s. 10). There were 33 patients (5 per cent) who did not wait or absconded after treatment commenced.

Approximately 50 per cent of mental health patients brought in by the police arrived under s. 10 of the Mental Health Act (see Appendix D); only 249 (38.2 per cent) arrived voluntarily. After ED assessment, 217 patients (33.3 per cent) remained involuntarily in hospital.

When brought in to the ED by police, 259 patients (39.8 per cent) were intoxicated: 160 (24.6 per cent) by alcohol and the rest by a typical mix of illicit drugs.

Referred to EDs only because no acute mental health bed available The study identifi ed a group of mental health patients who were referred to the ED only because there was no mental health bed available. These patients could have been direct admissions to the hospital had there been access to beds. In total, there were 430 such patients (11.6 per cent of all mental health presentations to the ED). Patients presenting to the ED only because there is no acute mental health bed tend to arrive earlier in the week and in the afternoon and evening. The trend of arriving earlier in the week may be due to access diffi culties resulting from fewer discharges over the weekend.

Mental health presentations to the emergency department 40

There was a marked variation in the proportion of this sub-group across the fi ve sites. The Alfred and Geelong Hospitals, with the lowest ED length of stay, had almost no presentations resulting from an acute mental health bed being unavailable, whereas over 50 per cent of presentations at Dandenong Hospital were because an acute mental health bed was unavailable. This result for Dandenong, combined with the signifi cantly longer total ED length of stay for this group, indicates prolonged ED stay was related to poorer access to a mental health bed.

Nearly 60 per cent of patients presenting only because there was no acute mental health bed stayed more than 12 hours in the ED and 30 per cent stayed more than 24 hours.

Note: LOS = length of stay For this sub-group of mental health patients, 17 per cent were intoxicated on arrival, 51.6 per cent required a special (one-on-one nursing), 88 per cent were admitted to a psychiatric ward, 62.1 per cent were involuntary admissions and 7.9 per cent arrived on a revoked community treatment order. The discharge diagnoses did not include poisoning or intoxication, but were suicidal thoughts, depression, psychosis or schizophrenia for 67 per cent. This is an important group of patients. They spent signifi cantly longer in the ED compared with all mental health patients and required greater resources, such as one-on-one nursing.

Appendix D: The Victorian Mental Health Act 1986

The Victorian Mental Health Act 1986 specifi es procedures under which involuntary psychiatric treatment can be administered to someone with a mental illness. The following explanation of the Act applies to the period of the research project. Amendments to the Mental Health Act which came into effect on 6 December 2004 have made some changes to these sections. Section 9 refers to the process for commencing involuntary treatment. A request can be made by any person over the age of 18 years. A recommendation that a person requires involuntary psychiatric treatment for a mental illness is completed by a medical practitioner. Section 10 refers to the power of the police to apprehend a person who they suspect has a mental illness and is at serious risk of suicide or harm to be assessed by a medical practitioner or mental health practitioner with a view to making a recommendation. Section 12 refers to the process of involuntary admission to an approved mental health service following the making of a request and recommendation. Involuntary treatment can occur by detaining a person as an inpatient in an approved mental health service or in the community under a community treatment order (CTO). Section 12 also requires a review of the admission be made within 24 hours by the authorised psychiatrist of the approved mental health service. The psychiatrist must either confi rm the admission or discharge the person if the criteria for involuntary treatment do not apply to the person. A revoked CTO occurs when the authorised psychiatrist believes the patient has not complied with involuntary treatment in the community or is no longer suitable for treatment in the community. A person subject to a revoked CTO must return to the approved mental health service as an inpatient. Mental health presentations to the emergency department 58

Defi nitions chemical restraint: the use of drugs to achieve rapid sedation or tranquillisation in the setting of severely agitated behaviour. This does not include the use of drugs for therapeutic purpose of mild sedation; for example, 5 mg oral Diazepam. physical restraint: the use of mechanical means to restrain a patient; for example, shackles manual restraint: a patient held down by others, without the use of physical restraints
