Perceived need for mental health care: influences of diagnosis, demography and disability.

BACKGROUND: Recent major epidemiological studies have adopted increasingly multidimensional approaches to assessment. Several of these have included some assessment of perceived need for mental health care. The Australian National Survey of Mental Health and Wellbeing, conducted in 1997, included a particularly detailed examination of this construct, with an instrument with demonstrated reliability and validity. METHODS: A clustered probability sample of 10641 Australians responded to the field questionnaire for this survey, including questions on perceived need either where there had been service utilization, or where a disorder was detected by administration of sections of the Composite International Diagnostic Interview. The confidentialized unit record file generated from the survey was analysed for determinants of perceived need. RESULTS: Perceived need is increased in females, in people in the middle years of adulthood, and in those who have affective disorders or co-morbidity. Effects of diagnosis and disability can account for most of the differences in gender specific rates. With correction for these effects through regression, there is less perceived need for social interventions and possibly more for counselling in females; disability is confirmed as strongly positively associated with perceived need, as are the presence of affective disorders or co-morbidity. CONCLUSIONS: The findings of this study underscore the imperative for mental health services to be attentive and responsive to consumer perceived need. The substantial majority of people who are significantly disabled by mental health problems are among those who see themselves as having such needs.

Australian general practice and the meeting of needs for mental health care.

BACKGROUND: This report, drawing on a national epidemiological survey conducted in 1997, examines the role of Australian medical general practitioners (GPs) in responding to needs for mental health care. METHODS: We analysed data from the Australian National Survey of Mental Health and Wellbeing (NSMHWB). The NSMHWB employed clustered probability sampling of all Australian adults, and 10,641 participants were interviewed. The field questionnaire included modules of the Composite International Diagnostic Interview, and instruments assessing disability, service utilisation and perceived needs for care. RESULTS: Eighty-four percent of people with a mental disorder consulted a GP in the year prior to survey, but only 29% consulted in relation to a mental health problem. GP services were seen as more responsive to needs for medication, counselling and information than needs for social interventions and skills training. People with perceived needs for counselling were more likely to consult with other providers, either as alternative or additional consultations to those with a GP. Counselling needs were reported as less well met when people saw a GP alone than when consulting other service providers. CONCLUSIONS: Many people with mental health problems attend primary medical care practitioners without presenting these problems to their physicians. When they do present, perceived needs for medication are rated as well met, but there is substantial unmet perceived need for interventions in social and occupational domains. Perceived needs for counselling are less well met where the GP is the sole provider. To close these identified gaps calls for improvements in primary care physicians' skills and effective collaborative models with other providers.

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.

Assessing perceived need for mental health care in a community survey: development of the Perceived Need for Care Questionnaire (PNCQ).

BACKGROUND: The Perceived Need for Care Questionnaire (PNCQ) was designed for the Australian National Survey of Mental Health and Wellbeing. The PNCQ complemented collection of data on diagnosis and disability with the survey participants' perceptions of their needs for mental health care and the meeting of those needs. The four-stage design of the PNCQ mimics a conversational exploration of the topic of perceived needs. Five categories of perceived need are each assigned to one of four levels of perceived need (no need, unmet need, partially met need and met need). For unmet need and partially met need, information on barriers to care is collected. METHODS: Inter-rater reliabilities of perceived needs assessed by the PNCQ were examined in a study of 145 anxiety clinic attenders. Construct validity of these items was tested, using a multi-trait multi-method approach and hypotheses regarding extreme groups, in a study with a sample of 51 general practice and community psychiatric service patients. RESULTS: The instrument is brief to administer and has proved feasible for use in various settings. Inter-rater reliabilities for major categories, measured by the kappa statistic, exceeded 0.60 in most cases; for the summary category of all perceived needs, inter-rater reliability was 0.62. The multi-trait multi-method approach lent support to the construct validity of the instrument, as did findings in extreme groups. CONCLUSIONS: The PNCQ shows acceptable feasibility, reliability and validity, adding to the range of assessment tools available for epidemiological and health services research.

Perceived need for mental health care, findings from the Australian National Survey of Mental Health and Well-being.

BACKGROUND: The Australian National Survey of Mental Health and Well-being was designed to detect and describe psychiatric morbidity, associated disability, service use and perceived need for care. The survey employed a single-phase interview methodology, delivering a field questionnaire to a clustered probability sample of 10,641 Australians. Perceived need was sampled with an instrument designed for this survey, the Perceived Need for Care Questionnaire (PNCQ). This questionnaire gathers information about five categories of perceived need, assigning each to one of four levels of perceived need. Reliability and validity studies showed satisfactory performance of the instrument. METHODS: Perceived need for mental health care in the Australian population has been analysed using PNCQ data, relating this to diagnostic and service utilization data from the above survey. RESULTS: The survey findings indicate that an estimated 13.8% of the Australian population have perceived need for mental health care. Those who met interview criteria for a psychiatric diagnosis and also expressed perceived need make up 9.9% of the population. An estimated 11.0% of the population are cases of untreated prevalence, a minority (3.6% of the population) of whom expressed perceived need for mental health care. Among persons using services, those without a psychiatric diagnosis based on interview criteria (4.4% of the population), showed high levels of perceived met need. CONCLUSIONS: The overall rate of perceived need found by this methodology lies between those found in the USA and Canada. The findings suggest that service use in the absence of diagnosis elicited by survey questionnaires may often represent successful intervention. In the survey, untreated prevalence was commonly not accompanied by perceived need for mental health care.

The pattern-of-care model: a tool for planning community mental health services.

In periods of change, psychiatric services must project outcomes of decisions about service innovations and reductions, including budgetary implications. To support such decision making, a public-sector psychiatric service in Melbourne, Victoria, Australia, developed a modeling tool that combines data from its service activity database and budgetary information with modeling techniques based on use of a spreadsheet. The model is based on clients' use of three major service components: the inpatient unit, continuing clinical care and consultancy services, and crisis assessment and treatment services. It classifies clients according to patterns of care-that is, whether they used one, two, or three of the components, in various combinations. The authors report service use and financial data derived from the model for the financial year 1992-1993. They describe two scenarios for using the model to project changes in patterns of care and costs when new services are implemented. Such a model can clarify costs, including opportunity costs, of management decisions and facilitate participation of senior clinicians in active service planning within the realities of budgetary constraints.

Geographical resource allocation for public mental health services in Victoria.

OBJECTIVE: To provide background information on the approach of area based funding models for mental health services, to describe the considerations which have come to bear in the development process of the Victorian model, to explore the impacts of different models, and to suggest courses for further development. METHOD: The history of this approach to funding in the UK and the USA is summarised, then an account is given of the development of the Victorian model. The position is put that the validation of such models is hampered by having only sparse relevant data. Suggestions are made for improving this situation. RESULTS: The Victorian model has come to include adjustments for socioeconomic disadvantage, the age, sex and marital status structure of the population, and a variable discounting for estimated substitutive activity of the private sector. Different methods of combining these adjustments into a working formula can be seen to have very different impacts. CONCLUSIONS: The approach taken in development of this model can be expected to have major influence on funding within Victoria, but also more widely in Australia. The impacts of differing assumptions within these models are significant. Specifically targeted epidemiological research, and activity analysis of the private sector will be necessary to enhance the validity of models of this type.

Police referrals to a psychiatric hospital: indicators for referral and psychiatric outcome.

Studies of police psychiatric referrals in the USA and the UK generally show these patients to be ill and in need of care. There are, however, no published Australian studies and such findings may not be validly generalised. This prospective study of consecutive police psychiatric referrals in Adelaide reports psychiatric assessment in 92 cases and observations by police in 69 of these, with no evidence of selection bias. The most common reason for referral was threat of self harm (28%). Mental illness was deemed to be present in 49% and the most common clinical description was "situational crisis" (29%). Schizophrenia was diagnosed in 18%. Clinicians viewed 19% of referrals as inappropriate. Increased relative odds for mental illness were associated with police accounts of psychotic symptoms, and decreased odds with threat of self harm and violence. Increased odds for admission were associated with language difficulties and damage to own property, decreased odds with threat to others, threat of suicide, and threat to self injury. There were 14 cases where possible charges were not being pursued: of these 7 were regarded as ill and 4 were regarded as inappropriate referrals. The rates of major disorders are lower than in other published work. It is proposed that this can be explained by relative ease of referral by police to psychiatry and flexible acceptance criteria.

Assessing schizophrenia in adults with mental retardation. A comparative study.

Twenty-five patients with mild mental retardation were compared with 26 schizophrenic patients of normal intelligence. The patients with retardation had suffered an earlier onset and were less likely to have been married or employed. However, the clinical phenomena exhibited by the two groups, as elicited by a SADS-L interview, were very similar. Thus, standardised interviews and criteria for schizophrenia can be readily applied to those with an IQ between 50 and 70.

Lysozyme synthesis in osteoclasts.

Osteoclasts may or may not be directly related to monocytes and macrophages, but it is well established that these cell types share a number of features in common. In the present study we sought to extend this comparison by assessing lysozyme synthesis in osteoclasts, an enzyme known to be produced and secreted in large amounts by monocytes and macrophages. Our data show that freshly isolated chicken osteoclasts and osteoclasts in situ contain an abundant amount of lysozyme and correspondingly high steady-state levels of the enzyme's messenger RNA. Marrow macrophages, at various stages of in vitro maturation, also possess lysozyme mRNA but in amounts approximately two to four times lower than osteoclasts. These observations reaffirm the monocyte-macrophage nature of the osteoclast but raise questions about the function of the lysozyme in this cell. At present, the role of the lysozyme in osteoclast activity remains unexplained.

Trial of three-day and ten-day courses of amoxycillin in otitis media.

A randomised double-blind controlled trial compared three-day and 10-day courses of amoxycillin (25 mg/kg daily) in children with otitis media. Seventeen doctors from five centres admitted 84 children between the ages of 2 and 10 years. Symptoms and signs were measured on admission to the trial, on day 3, and on day 15. Mother's observations were recorded daily for 10 days. Audiograms were performed at four and 12 weeks after the end of the trial. The treatment groups showed little difference in the speed of resolution of symptoms and signs, the numbers of primary treatment failures, or the frequency of recurrent ear infections. There were no complications in either group. Most children with otitis media can probably be successfully and safely treated with no more than a three-day course of amoxycillin providing their progress is reviewed about the fifth or sixth day after treatment started. This policy could save over 1 million pounds annually in antibiotic costs.

Bronchospasm during excretory urography: lack of specificity for the methylglucamine cation.

UNLABELLED: Pulmonary function (specifically, forced expiratory volume in 1 sec and forced expiratory flow at low lung volumes) was measured with maximal expiratory flow-volume curves during excretory urography in 70 patients and during sham procedures in 27 subjects. Forty-one patients received a 100 ml intravenous bolus of 60% methylglucamine diatrizoate and 29 patients received 100 ml of 50% sodium diatrizoate. Within 20 min, greater than 95% of patients had bronchospasm as indicated by asymptomatic decreases in pulmonary function. These decreases were significantly (p less than 0.001) greater than in the subjects undergoing sham procedures. Greater than 50% of patients had a maximum decrease in pulmonary function that exceeded the range of variability for consecutive repetitions of maximal expiratory flow-volume curves. These patients were classified as responders during excretory urography. The prevalence of responders was similar in methylglucamine diatrizoate and sodium diatrizoate patients. The magnitude of maximum decreases in pulmonary function did not differ significantly between methylglucamine diatrizoate and sodium diatrizoate responders. CONCLUSIONS: Sodium diatrizoate does not offer an advantage over methylglucamine diatrizoate with respect to asymptomatic bronchospasm during excretory urography.
