Queensland's geographical maldistribution of psychiatrists and Queensland Health's response.

There is a major geographical maldistribution and shortage of psychiatrists throughout Queensland. In June 1992, 48 psychiatrists worked outside of Brisbane where 66% of the population reside, while 172 psychiatrists worked in the metropolitan area. The reasons for and the effects of the maldistribution are discussed. Since 1991, Queensland Health has developed a number of key strategies to attract and retain psychiatrists in our non-metropolitan areas. These strategies are outlined. Between July 1992 and December 1993, 14 new full time psychiatrists were recruited. The results of these strategies are encouraging.

Recruitment and retention of psychiatrists in non-metropolitan public positions in Queensland: research on "Queensland Health's response'.

OBJECTIVE: To evaluate Queensland Health's recruitment campaign of 15 fulltime psychiatrists to non-metropolitan areas between July 1992 and December 1993. METHOD: A detailed 170-item Likert-type questionnaire was designed and mailed to all 15 psychiatrists. Thirteen questionnaires were completed and followed-up by a face to face interview. RESULTS: Findings indicate that most of those recruited were experienced senior specialists who came to the positions as result of personal contact and were attracted to non-metropolitan positions because of 'lifestyle' and professional challenge' variables. 'Lifestyle' and 'professional' variables were identified as major contributors to their retention. They reported that 'bureaucracy' and 'social and family' reasons would be the most likely cause of them considering leaving their current positions. CONCLUSIONS: While the recruitment campaign was evaluated as successful, some aspects were clearly more influential than others. It was noted that factors which were likely to influence psychiatrists to leave non-metropolitan public sector positions were more 'public' than 'non-metropolitan' in nature.

Helminth control in Queensland beef cattle: comparison of part paddock and whole paddock treatment in the wallum of south eastern Queensland.

An increase in the body weight gain of beef calves due to a reduction in the overall larval nematode challenge and a consequent reduction in the host response to infection was observed on fertilised, improved pasturesin the wallum country of south eastern Queensland. Three groups of calves were used. Group 1 consisted of 15 calves and their dams on 20 ha, all receiving monthly injectable tetramisole. Groups 2 and 3 consisted each of 15 calves and dams grazing 40 ha with only the 15 calves of Group 2 receiving monthly tetramisole. The trial concluded after 10 months when the mean body weight gains made by calves of Groups 1, 2 and 3 were 206 kg. 177 kg and 168 kg respectively. These differences proved statistically significant. All heifers from these groups were sold soon after the conclusion of the trial and sale prices of heifers from Group 1 were 11% higher than those from Group 2 and 21% higher than those from Group 3. During this work the predominat parasitic nematode present was cooperia spp H. placei and O. ostertagi were also prevalent species and O.E. radiatum was present in low numbers.

Rodent zoonoses in North Queensland: the occurrence and distribution of zoonotic infections in North Queensland rodents.

A study of potentially zoonotic infections was carried out on 351 rodents trapped in north-eastern Queensland. Their ecosystems included towns, agricultural and livestock areas, wookland and rainforest. Nine serotypes of salmonellae were obtained from asymptomatic carries in predominantly settled locations. Two strains of Ps. pseudomallei occurred in rainforest near Innisfail and one on a cattle property adjacent to Townsville. Ps. aeruginosa caused bronchopneumonia in one animal from Townsville harbour. Ifection by leptospirae of six serogroups and seven serovars were identified by serological or cultural examinations. Enzootic foci occurred on the Mount Spec rainforest where celledoni and australis were being excreted by rats adjacent to the Paluma dam system. In addition to the scrub typhus locations at Rocky Creek, Atherton Tableland and Bullocky Creek, near Ingham, which were confirmed, a new focus of infection by R. tsutsugamushi was identified at El Arish near Tully. Water rat (H. chrysogaster) at Townsville harbour constituted a reservoir of toxoplasmosis. In addition to the known human pathogenic helminths H. nana and H. diminuta, localized foci of hookworms (Ancylostoma spp.) were found. Histological evidence of cytomegalic disease of the salivary glands or kidneys was a common finding.

Seasonal abundance of Culex annulirostris and other mosquitoes at Kowanyama, north Queensland, and Charleville, south west Queensland.

At Kowanyama, 104,006 adult female mosquitoes of a probable 47 species were collected on twelve occasions from April, 1972, to April, 1976. At Charleville, 71,791 adult females of 20 taxa were taken during thirteen periods from February, 1974, to February, 1976. Culex annulirostris was predominant at Kowanyama and especially at Charleville where it comprised up to 99% of dry season collections. Culex fatigans, Ae normanensis, An annulipes and, at Kowanyama only, An bancroftii were the other major species collected. Several bait trapping methods were suitable for monitoring densities of Cx annulirostris and other species but mammalian baits were best. Because Cx annulirostris activity continued throughout winter even at Charleville, continuous cycles of arbovirus transmission are possible, although the potential of dormant Aedes eggs also bears investigation as a method of arbovirus survival.

The Queensland Cancer Risk Study: behavioural risk factor results.

OBJECTIVE: To describe the population prevalence of key cancer risk behaviours in Queensland. METHODS: The Queensland Cancer Risk Study was a population-based survey of 9,419 Queensland residents aged 20-75 years. Information was collected through an anonymous, computer-assisted telephone interview between February and November 2004. Outcome measures included tobacco smoking, alcohol consumption, sun-tanning and sunburn, obesity, physical inactivity and poor diet, weighted by age, gender and geographic region. RESULTS: Prevalence of current smoking was 25.2% for males and 20.8% for females and was highest in the 20-39 year age group and in rural/remote areas. Two-thirds of participants regularly drank alcohol; of these, 63% consumed excessive amounts of alcohol. Excessive sun exposure is still a problem; 70% of Queenslanders reported an episode of sunburn and 12% reported attempting to get a suntan in the past year. More than half of the respondents (53.9%) were above the healthy weight range, and 17.1% of males and 18.4% of females were obese. Just over 40% of Queensland adults reported having insufficient levels of physical activity. Fewer than half of the participants met recommended levels of fruit or vegetable consumption. CONCLUSIONS AND IMPLICATIONS: The majority of Queensland adults exhibit known, modifiable cancer risk behaviours. These results suggest that continuing efforts to reduce the prevalence of these risk factors are warranted. Specifically, significant gains could be made by targeting behaviour change programs at younger Queenslanders (aged 20-39 years), men, and those living in remote/ very remote areas of Queensland.

Time trends of cutaneous melanoma in Queensland, Australia and Central Europe.

BACKGROUND: The objective of this study was to describe recent developments in cutaneous melanoma from the German speaking countries in Europe (Germany, Austria, and Switzerland) and from Queensland, Australia. METHODS: All incident invasive cutaneous melanoma cases recorded between 1986 and 1996 by the Queensland Melanoma Register and by the Central Malignant Melanoma Registry of the German Dermatological Society were included in the analysis. Weighted linear trend analyses were performed to assess significant changes over the years using yearly sample sizes as weights. RESULTS: In Central Europe, the median tumor thickness decreased from 1.2 mm in 1986 to 0.8 mm in 1996 (P < 0.001), whereas it varied insignificantly between 0.5 mm and 0.6 mm in Queensland. The percentage of patients with Clark Level II invasion increased significantly in Queensland (P < 0.001; 1996, 61.1%) and in Central Europe (P = 0.041; 1996, 24.5%). The percentage of superficial spreading melanomas rose in Central Europe (P = 0.043; 1996, 64.4%), whereas it decreased slightly in Queensland (P = 0.032; 1996, 75%). In Queensland and in Central Europe, younger people and women presented more frequently with thinner melanomas (</= 0.75 mm). CONCLUSIONS: In both Central Europe and Queensland, trends toward thinner and less invasive melanomas were observed between 1986 and 1996, although the median tumor thickness decreased significantly only for Central European data. Men and elderly individuals should be the focus of health-promotion activities, because they tended to present on average with thicker and prognostically poorer melanomas.
