Real-Time Suicide Surveillance: Comparison of International Surveillance Systems and Recommended Best Practice

OBJECTIVE

Some countries have implemented systems to monitor suicides in real-time. These systems differ because of the various ways in which suicides are identified and recorded. The main objective of this study was to conduct an international comparison of major real-time suicide mortality surveillance systems to identify joint strengths, challenges, and differences, and thereby inform best-practice criteria at local, national, and international levels.

METHODS

Five major real-time suicide mortality surveillance systems of various coverage levels were identified and selected for review via an internet-based scoping exercise and prior knowledge of existing systems. Key information including the system components and practices was collated from those organizations that developed and operate each system using a structured template. The information was narratively and critically synthesized to determine similarities and differences between the systems.

RESULTS

The comparative review of the five established real-time suicide surveillance systems revealed more commonalities than differences overall. Commonalities included rapid, routine surveillance based on minimal, provisional data to facilitate timely intervention and postvention efforts. Identified differences include the timeliness of case submission and system infrastructure.

CONCLUSION

The recommended criteria could promote replicable components and practices in real-time suicide surveillance while offering flexibility in adapting to regional/local circumstances and resource availability.HIGHLIGHTSEvidence-informed recommendations for current best practice in real-time suicide surveillance.Proposed comprehensive framework can be adapted based on available resources and capacity.Real-time suicide mortality data facilitates rapid data-driven decision-making in suicide prevention.

Structural intervention at one bridge decreases the overall jumping suicide rate in Victoria, Australia

AIMS

There is clear evidence that installing safety barriers is effective in preventing jumping suicides from high-risk bridges with only moderate displacement to other nearby bridges. However, the impact of barriers on jumping suicides across broader geographical areas is not well understood. We examined patterns in jumping suicides across the state of Victoria, Australia, after a safety barrier was installed at the West Gate Bridge which, before the installation of the barrier, was the site of approximately 40% of Victoria's jumping suicides.

METHODS

We used negative binomial regression analyses on Victorian data from 2000 to 2019 to compare rates of jumping suicides at the West Gate Bridge, other bridges and non-bridge jumping locations before, during and after the West Gate Bridge barrier installation. We conducted linear regression analyses to examine whether the distance travelled from the deceased's usual residence to the location of their jumping suicide changed between the before, during and after barrier installation periods.

RESULTS

After installation of the barrier, there were no jumping suicides at the West Gate Bridge (rate ratio [RR] = 0.00, 95% credible intervals [95% Cr] = 0.00-0.0001) and there was strong evidence that the rate of jumping suicides at all locations declined by 65% (RR = 0.35, 95% Cr = 0.22-0.54). At other bridges, there was also evidence of a reduction (RR = 0.31, 95% Cr = 0.11-0.70), but there was no evidence of a change at non-bridge locations (RR = 0.74, 95% Cr = 0.39-1.30).

CONCLUSION

After installation of the safety barrier at the West Gate Bridge, jumping suicide in Victoria decreased overall and at other bridges, and did not appear to change at non-bridge locations. Our findings show that when barriers are installed at a site responsible for a disproportionately high number of jumping suicides, they are not only highly effective at the site where the barriers are installed but can also have a prevention impact beyond the immediate locale at similar sites.

Suicide Trends during the COVID-19 pandemic and the International COVID-19 Suicide Prevention Research Collaboration

Introduction

There was and still is much speculation about the COVID-19 pandemic impact on suicide rates. We aimed to assess the effect of the COVID-19 pandemic on suicide rates around the world.

Methods

We sourced real-time suicide data from countries or countries areas through a systematic internet search (official websites of Ministries of health, police agencies, and government-run statistics agencies or equivalents), recourse to our networks (e.g. ICSPRC) and the published literature (a living systematic review). We used an interrupted time-series analysis to model the trend in monthly suicides before COVID-19 in each country or country area, comparing the expected number of suicides derived from the model with the observed number of suicides in the early months of the pandemic (from April 1 to July 31, 2020, in the primary analysis). We have now updated this work to cover the first 15 months of the pandemic and stratified analyses by age and sex and method. We will present findings from the new updated data (35 countries) at the conference.

Results

Initially we sourced data from 21 countries (16 high-income and five upper-middle-income countries). Rate ratios (RRs) and 95% CIs based on the observed versus expected numbers of suicides showed no evidence of a significant increase in risk of suicide since the pandemic began in any country or area. There was statistical evidence of a decrease in suicide compared with the expected number in 12 countries or areas.

Conclusions

This was the first study to examine suicides occurring in the context of the COVID-19 pandemic in multiple countries. Early on high-income and upper-middle-income countries, suicide numbers remained largely unchanged or declined compared with the expected levels based on the pre-pandemic period. We need to remain vigilant and be poised to respond as the longer-term mental health and economic effects of the pandemic unfold. We will present updated findings with more recent data.

A state level analyses of suicide and the COVID-19 pandemic in Mexico

BACKGROUND

While suicide rates in high- and middle-income countries appeared stable in the early stages of the pandemic, we know little about within-country variations. We sought to investigate the impact of COVID-19 on suicide in Mexico's 32 states and to identify factors that may have contributed to observed variations between states.

METHODS

Interrupted time-series analysis to model the trend in monthly suicides before COVID-19 (from Jan 1, 2010, to March 31, 2020), comparing the expected number of suicides derived from the model with the observed number for the remainder of the year (April 1 to December 31, 2020) for each of Mexico's 32 states. Next, we modeled state-level trends using linear regression to study likely contributing factors at ecological level.

RESULTS

Suicide increased slightly across Mexico during the first nine months of the pandemic (RR 1.03; 95%CI 1.01-1.05). Suicides remained stable in 19 states, increase in seven states (RR range: 1.12-2.04) and a decrease in six states (RR range: 0.46-0.88). Suicide RR at the state level was positively associated with population density in 2020 and state level suicide death rate in 2019.

CONCLUSIONS

The COVID-19 pandemic had a differential effect on suicide death within the 32 states of Mexico. Higher population density and higher suicide rates in 2019 were associated with increased suicide. As the country struggles to cope with the ongoing pandemic, efforts to improve access to primary care and mental health care services (including suicide crisis intervention services) in these settings should be given priority.

Socioeconomic Disadvantage, Mental Health and Substance Use in Young Men in Emerging Adulthood

Emerging adulthood is a neglected phase of the life course in health research. Health problems and risk behaviors at this time of life can have long-term consequences for health. The 2016 Lancet Commission on Adolescent Health and Wellbeing reported that the influence of socioeconomic factors was under-researched among adolescents and young adults. Moreover, the influence of socioeconomic factors on health has been little researched specifically in emerging adult men. We aimed to investigate associations between socioeconomic disadvantage and mental health, suicidal behavior, and substance use in young adult Australian men. Logistic regression was used to examine the association between Year 12 (high school) completion and area disadvantage on mental health, suicidal behavior, and substance use in 2,281 young men age 18-25 participating in the Australian Longitudinal Study on Male Health (Ten to Men). In unadjusted analysis both Year 12 non-completion and area disadvantage were associated with multiple adverse outcomes. In adjusted analysis Year 12 non-completion, but not area disadvantage, was associated with poorer mental health, increased odds of suicidal behavior, and substance use. Retaining young men in high school and developing health-promotion strategies targeted at those who do exit education early could both improve young men's mental health and reduce suicidal behavior and substance use in emerging adulthood.

The Mortality After Release from Incarceration Consortium (MARIC): Protocol for a multi-national, individual participant data meta-analysis

INTRODUCTION

More than 30 million adults are released from incarceration globally each year. Many experience complex physical and mental health problems, and are at markedly increased risk of preventable mortality. Despite this, evidence regarding the global epidemiology of mortality following release from incarceration is insufficient to inform the development of targeted, evidence-based responses. Many previous studies have suffered from inadequate power and poor precision, and even large studies have limited capacity to disaggregate data by specific causes of death, sub-populations or time since release to answer questions of clinical and public health relevance.

OBJECTIVES

To comprehensively document the incidence, timing, causes and risk factors for mortality in adults released from prison.

METHODS

We created the Mortality After Release from Incarceration Consortium (MARIC), a multi-disciplinary collaboration representing 29 cohorts of adults who have experienced incarceration from 11 countries. Findings across cohorts will be analysed using a two-step, individual participant data meta-analysis methodology.

RESULTS

The combined sample includes 1,337,993 individuals (89% male), with 75,795 deaths recorded over 9,191,393 person-years of follow-up.

CONCLUSIONS

The consortium represents an important advancement in the field, bringing international attention to this problem. It will provide internationally relevant evidence to guide policymakers and clinicians in reducing preventable deaths in this marginalized population.

Clusters of suicides and suicide attempts: detection, proximity and correlates

BACKGROUND

A suicide cluster is defined as a higher number of observed cases occurring in space and/or time than would typically be expected. Previous research has largely focused on identifying clusters of suicides, while there has been comparatively limited research on clusters of suicide attempts. We sought to identify clusters of both types of behaviour, and having done that, identify the factors that distinguish suicide attempts inside a cluster from those that were outside a cluster.

METHODS

We used data from Western Australia from 2000 to 2011. We defined suicide attempts as admissions to hospital for deliberate self-harm and suicides as deaths due to deliberate self-harm. Using an analytic strategy that accounted for the repetition of attempted suicide within a cluster, we performed spatial-temporal analysis using Poisson discrete scan statistics to detect clusters of suicide attempts and clusters of suicides. Logistic regression was then used to compare clustered attempts with non-clustered attempts to identify risk factors for an attempt being in a cluster.

RESULTS

We detected 350 (1%) suicide attempts occurring within seven spatial-temporal clusters and 12 (0.6%) suicides occurring within two spatial-temporal clusters. Both of the suicide clusters were located within a larger but later suicide attempt cluster. In multivariate analysis, suicide attempts by individuals who lived in areas of low socioeconomic status had higher odds of being in a cluster than those living in areas of high socioeconomic status [odds ratio (OR) = 29.1, 95% confidence interval (CI) = 6.3-135.5]. A one percentage-point increase in the proportion of people who had changed address in the last year was associated with a 60% increase in the odds of the attempt being within a cluster (OR = 1.60, 95% CI = 1.29-1.98) and a one percentage-point increase in the proportion of Indigenous people in the area was associated with a 7% increase in the suicide being within a cluster (OR = 1.07, 95% CI = 1.00-1.13). Age, sex, marital status, employment status, method of harm, remoteness, percentage of people in rented accommodation and percentage of unmarried people were not associated with the odds of being in a suicide attempt cluster.

CONCLUSIONS

Early identification of and responding to suicide clusters may reduce the likelihood of subsequent clusters forming. The mechanisms, however, that underlie clusters forming is poorly understood.

Gender-related patterns and determinants of recent help-seeking for past-year affective, anxiety and substance use disorders: findings from a national epidemiological survey

AIMS

To examine: (1) gender-specific determinants of help-seeking for mental health, including health professional consultation and the use of non-clinical support services and self-management strategies (SS/SM) and; (2) gender differences among individuals with unmet perceived need for care.

METHOD

Analyses focused on 689 males and 1075 females aged 16-85 years who met ICD-10 criteria for a past-year affective, anxiety or substance use disorder in an Australian community-representative survey. Two classifications of help-seeking for mental health in the previous year were created: (1) no health professional consultation or SS/SM, or health professional consultation, or SS/SM only, and; (2) no general practitioner (GP) or mental health professional consultation, or GP only consultation, or mental health professional consultation. Between- and within-gender help-seeking patterns were explored using multinomial logistic regression models. Characteristics of males and females with unmet perceived need for care were compared using chi-square tests.

RESULTS

Males with mental or substance use disorders had relatively lower odds than females of any health professional consultation (adjusted odds ratio [AOR] = 0.46), use of SS/SM only (AOR = 0.59), and GP only consultation (AOR = 0.29). Notably, males with severe disorders had substantially lower odds than females of any health professional consultation (AOR = 0.29) and GP only consultation (AOR = 0.14). Most correlates of help-seeking were need-related. Many applied to both genders (e.g., severity, disability, psychiatric comorbidity), although some were male-specific (e.g., past-year reaction to a traumatic event) or female-specific (e.g., past-year affective disorder). Certain enabling and predisposing factors increased the probability of health professional consultation for both genders (age 30+ years) or for males (unmarried, single parenthood, reliance on government pension). Males with unmet perceived need for care were more likely to have experienced a substance use disorder and to want medicine or tablets or social intervention, whereas their females peers were more likely to have experienced an anxiety disorder and to want counselling or talking therapy. For both genders, attitudinal/knowledge barriers to receiving the types of help wanted (e.g., not knowing where to get help) were more commonly reported than structural barriers (e.g., cost).

CONCLUSIONS

Findings suggest a need to address barriers to help-seeking in males with severe disorders, and promote GP consultation. Exploring gender-specific attitudinal/knowledge barriers to receiving help, and the types of help wanted, may assist in designing interventions to increase consultation. Mental health promotion/education efforts could incorporate information about the content and benefits of evidence-based treatments and encourage males to participate in other potentially beneficial actions (e.g., physical activity).

Suicide and the media. Part II: Portrayal in fictional media

The association between the portrayal of suicide in fictional media and actual suicide has been debated since 1774, when it was asserted that Goethe's The Sorrows of Young Werther had led people to take their own lives. Since that time, a plethora of studies considering the association has been conducted. This review considered 34 studies examining the impact of fictional portrayal of suicide (in film and television, music, and plays) on actual suicidal behavior. It asked the question: "Is there any association, and if so, can it be considered causal?" Using strict criteria to establish causality, we found that the evidence was more equivocal than was the case for nonfictional reporting.

Suicide and the media. Part I: Reportage in nonfictional media

Numerous studies have considered the association between media reporting and portrayal of suicide and actual suicidal behavior or ideation. This review considered 42 studies that have examined the nonfiction media (newspapers, television, and books). Consideration was given to the extent to which inferences could be made about the relationship between portrayal of suicide in the given media and actual suicidal behavior in terms of: the strength of its association; and the extent to which it could be considered causal. The review demonstrated that there is an association between nonfictional media portrayal of suicide and actual suicide. The association satisfies sufficient of the criteria of consistency, strength, temporality, specificity and coherence for it to be deemed causal.

Suicide and the media. Part III: Theoretical issues

The body of evidence suggests that there is a causal association between nonfictional media reporting of suicide (in newspapers, on television, and in books) and actual suicide, and that there may be one between fictional media portrayal (in film and television, in music, and in plays) and actual suicide. This finding has been explained by social learning theory. The majority of studies upon which this finding is based fall into the media "effects tradition," which has been criticized for its positivist-like approach that fails to take into account of media content or the capacity of audiences to make meaning out of messages. A cultural studies approach that relies on discourse and frame analyses to explore meanings, and that qualitatively examines the multiple meanings that audiences give to media messages, could complement the effects tradition. Together, these approaches have the potential to clarify the notion of what constitutes responsible reporting of suicide, and to broaden the framework for evaluating media performance.

Evaluating complex, collaborative programmes: the Partnership Project as a case study

OBJECTIVE

In Australia, mental health services are delivered by a complex web of public- and private-sector providers. There is a growing recognition that linkages between these groups are not optimal, and a concern that this may lead to poor outcomes. This paper illustrates a conceptual framework for developing, implementing and evaluating programmes concerned with linkages.

METHOD

Drawing on theoretical and practical literature, this paper identifies different levels of integration, issues in evaluating programmes to address poor linkages, and features of useful evaluations. Within this context, it describes the method by which the Public and Private Partnerships in Mental Health Project (Partnership Project) is being evaluated. Conducted by St Vincent's Mental Health Service and The Melbourne Clinic, this is one of several Demonstration Projects in Integrated Mental Health Care funded under the National Mental Health Strategy.

RESULTS

Collaboration is hard to conceptualize and collaborative programmes usually have many players and components, and tend to operate within already-complex systems. This creates difficulties for evaluation, in terms of what to measure, how to measure it, and how to interpret findings. In spite of these difficulties, the illustrative example demonstrates a model for evaluating collaborative programmes that is currently working well because it is strongly conceptualized, descriptive, comparative, constructively sceptical, positioned from the bottom up, and collaborative.

CONCLUSIONS

This model, or aspects of it, could be extended to the evaluation of other mental health programmes and services that have collaborative elements.

Access to Australian mental health care by people from non-English-speaking backgrounds

OBJECTIVE

This study aimed to examine access to mental health care for people from non-English-speaking backgrounds relative to that of people from English-speaking backgrounds, in the context of the mental health status of both groups; and to consider whether, if they perceive that they have needs for care, these needs are met.

METHOD

The study used data from the population-based Australian National Survey of Mental Health and Wellbeing, conducted in 1997.

RESULTS

People from non-English-speaking backgrounds and English-speaking backgrounds were equally likely to experience anxiety disorders and affective disorders, but the former were less likely to experience substance-use disorders and any mental disorder. When those with each disorder type were considered alone, people from non-English-speaking backgrounds and English-speaking backgrounds were equally likely to use services for mental health problems. When those with perceived needs for care were considered in isolation, there was no difference between birthplace groups in terms of their likelihood of reporting that their needs were fully met.

CONCLUSIONS

The study had several limitations (i.e. lack of detail on specific ethnic groups and exclusion of potential respondents who could not speak English), which mean that these findings should be interpreted with caution. There is a need to build on this population-based work, by oversampling people from particular non-English speaking communities and ensuring that those who do not speak English are included in population samples. Such work will further clarify the relative ability of people from non-English-speaking backgrounds to access services, and the extent to which their needs are met.

Self-reported needs for care among persons who have suicidal ideation or who have attempted suicide

This study examined the self-reported needs of suicidal users of mental health services and the extent to which needs were met. Data on 10,641 adults were available from the Australian National Survey of Mental Health and Wellbeing. In the year before the survey, 245 persons with suicidal ideation used services, 37 of whom had attempted suicide. Suicidal persons reported a range of needs, especially for counseling, medication, and information. More than half of those with suicidal ideation and those who had attempted suicide who reported any needs felt that their needs had not been fully met. Suicidal persons were significantly more likely to perceive that they had needs.

Lessons from a comprehensive clinical audit of users of psychiatric services who committed suicide

OBJECTIVE

Characteristics of patients who committed suicide were examined to provide a picture of the treatment they received before death and to determine whether and how the suicides could have been prevented by the service system.

METHODS

The unnatural-deaths register was matched to the psychiatric case register in the state of Victoria in Australia to identify suicides by people with a history of public-sector psychiatric service use who committed suicide between July 1, 1989, and June 30, 1994. Data on patient and treatment characteristics were examined by three experienced clinicians, who made judgments about whether the suicide could have been prevented had the service system responded differently. Quantitative and qualitative data were descriptively analyzed.

RESULTS

A total of 629 psychiatric patients who had committed suicide were identified. Seventy-two percent of the patients were male, 62 percent were under 40 years old, and 51 percent were unmarried. They had a range of disorders, with the most common being schizophrenia or schizoaffective disorder (36 percent). Sixty-seven percent had previously attempted suicide. A total of 311 patients (49 percent) received care within four weeks of death. Twenty percent of the suicides were considered preventable. Key factors associated with preventability were poor staff-patient relationships, incomplete assessments, poor assessment and treatment of depression and psychological problems, and poor continuity of care.

CONCLUSIONS

Opportunities exist for the psychiatric service system to alter practices at several levels and thereby reduce patient suicides.

Suicidal ideation and suicide attempts among Australian adults

Too little is known about suicidal thoughts and behaviors at a population level to recommend appropriate preventive strategies. Using data from the Australian National Survey of Mental Health and Wellbeing (NSMHWB), this study examined rates of, and risk factors for, suicidal ideation and suicide attempts. For 10,641 respondents, the 12-month and lifetime cumulative incidence rates of suicidal ideation were 3.4% and 16.0%, respectively; the 12-month and lifetime cumulative incidence rates of suicide attempts were 0.4% and 3.6%, respectively. 12-month ideation was associated with anxiety disorders (relative risk ratio [RRR] = 3.51; population attributable risk percent [PAR%] = 19.6%), affective disorders (RRR = 11.94; PAR% = 38.8%) and substance abuse disorders (RRR = 1.85; PAR% = 6.1%). Attempts in the past 12 months were also associated with anxiety disorders (RRR = 7.06; PAR% = 37.0%), affective disorders (RRR = 12.24; PAR% = 39.5%), and substance abuse disorders (RRR = 2.09; PAR% = 7.7%). Age, marital status, and disability were associated with ideation; marital status and employment status with attempts. Approximately 12% of ideators in the sample progressed to making an attempt; employment status was the only significant predictor. Reducing suicidal ideation and attempts requires a multi-faceted approach that targets those with mental illness but also adopts population-based strategies that address other factors, such as unemployment.

Suicide attempts by psychiatric patients in acute inpatient, long-stay inpatient and community care

BACKGROUND

This study examined rates of and risk factors associated with suicide attempts by psychiatric patients under active care. It was especially focussed on the relative rates across three standard treatment settings: acute inpatient care, long-stay inpatient care and community-based care.

METHODS

A total of 12,229 patients in 13,632 episodes of care were rated on the Health of the Nation Outcome Scales (HoNOS) Item 2. For the purposes of the current investigation, a score of 4 was deemed to indicate a suicide attempt.

RESULTS

Incidence densities per 1000 episode days were 5.4 (95% CI = 4.8-6.1) for patients under care in acute inpatient settings, 0.6 (95% CI = 0.5-0.8) for patients under care in long-stay inpatient settings, and 0.5 (95% CI = 0.5-0.6) for patients under care in community-based arrangements. Predictors varied by treatment setting. Risk was elevated for personality disorders across all settings: 22.7 attempts per 1000 episode days (95% CI = 17.2-30.0) in acute inpatient care; 2.1 (95% CI = 1.0-4.5) in long-stay inpatient care; and 2.3 (95% CI = 1.7-3.0) in community-based care. This effect remained after adjustment for demographics.

CONCLUSION

Rates of suicide attempts among psychiatric patients are a major issue facing contemporary mental health care systems, and risk factors vary across different treatment settings.

Immunisation initiatives in general practice. Important lessons from division projects

AIM

To examine immunisation projects undertaken by divisions of general practice through the Divisions and Project Grants Program in the period from 1993 to mid 1997.

METHOD

A simple descriptive frequency analysis was conducted of information from the National Information Service Divisions Project database and evaluation reports of the project characteristics and methodology such as: year commenced; duration; location; funding; target groups; intervention; needs assessment; aim(s); study design; measurement (assessment) and outcome(s).

RESULTS

Forty-four funded immunisation projects were identified and of these, 12 projects with completed evaluation reports were analysed. Most projects were of 12-14 months duration, and were funded for a mean of $56,349 and median of $46,348 for the 44 funded projects and a mean $44,348 and median $40,318 for the 12 with evaluation reports. Most projects included a needs assessment. The main target groups were general practitioners, the general community, and children. Of the wide spectrum of interventions used, education and/or promotion and register and/or reminder systems were the most common. Study designs, the quality of measurement and outcomes were variable.

CONCLUSION

In the future with the move to outcome based block funding, it will be important for projects to adopt broader target groups, refine and develop interventions and develop greater sustainability through responding to local needs, improving design and evaluation and ongoing funding.

Suicide and recency of health care contacts. A systematic review

BACKGROUND

Many countries have set targets for suicide reduction, and suggested that mental health care providers and general practitioners have a key role to play.

METHOD

A systematic review of the literature.

RESULTS

Among those in the general population who commit suicide, up to 41% may have contact with psychiatric inpatient care in the year prior to death and up to 9% may commit suicide within one day of discharge. The corresponding figures are 11 and 4% for community-based psychiatric care and 83 and 20% for general practitioners.

CONCLUSIONS

Among those who die by suicide, contact with health services is common before death. This is a necessary but not sufficient condition for clinicians to intervene. More work is needed to determine whether these people show characteristic patterns of care and/or particular risk factors which would enable a targeted approach to be developed to assist clinicians in detecting and managing high-risk patients.

Integrating general practice and hospital services

OBJECTIVES

To evaluate a model of negotiations between six Divisions of General Practice and four teaching hospitals, aimed at creating formal agreements to improve the GP-hospital interface.

METHOD

The evaluation examined the model's outcomes and participants' experiences. Outcomes were investigated via unstructured interviews with key informants, and analysis of relevant documentation. Participants' experiences were elicited via structured interviews with 11 Divisional members and 14 hospital representatives.

RESULTS

Progress towards agreements was made in all cases, with a full agreement being reached at one hospital. Negotiations are continuing in the remaining hospitals. Additional outcomes were achieved during the process, and included resources and structural arrangements involving GPs. Participants were satisfied with the model, but certain key issues were identified.

CONCLUSION

This evaluation suggests that for negotiations between GPs and hospitals to be successful, Divisions must be involved and be representative, hospitals must see value in formal agreements, their structure must be considered and the process must be collaborative. In the current policy context, which emphasises primary care, hospitals and GPs are increasingly likely to start working more cooperatively. This model has significant potential to improve the interface between the two parties, through its formal negotiation process, and could easily be adapted to other settings.

General practitioners in hospitals

The authors review General Practitioners in Hospitals, a report prepared by the School of Medical Education, University of New South Wales (1993) for the Australian Health Ministers' Advisory Council Medical Workforce Group on Hospital Training and Career Development. The authors acknowledge that this report represents the most comprehensive look at GP involvement in hospitals across Australia, but suggest that its conclusion 'general practitioners play a substantial role in the provision of medical care in public hospitals around Australia' may be an overstatement. They discuss shortcomings associated with the study, including: definitional issues; variation in levels of involvement according to hospital type; potential biases introduced by using self-report of hospital administrators as the source of data; insufficient emphasis being placed on the views of GPs; and the validity of extrapolations.

Behavioural and EEG responses to auditory stimuli during sleep in newborn infants and in infants aged 3 months

Two studies were conducted in order to assess EEG and behavioural responsiveness to auditory stimuli as a function of sleep state in infants. The subjects in the first experiment were 11 infants aged 3 months, and in the second study the responsiveness of 8 infants aged 3 months was compared with that of 8 newborn infants. The stimuli ranged in intensity from 36 to 90 dB and were presented using a modification of the method of constant stimuli. The occurrence and intensity of behavioural responses were recorded by a trained observer. Electroencephalogram (EEG) responses were defined as EEG desynchronization and were identified by a Fast Fourier Transform algorithm. The results of the two studies showed that infants were more responsive during active sleep (AS) than during quiet sleep (QS) and gave behavioural responses at lower stimulus intensities than EEG responses. Behavioural responsiveness and EEG responsiveness during AS increased as a function of age, while EEG responsiveness during QS decreased. The marked suppression of EEG responsiveness during QS at 3 months of age is thought to be a consequence of developmental changes in sleep mechanisms--an effect which may have clinical implications.
