Rising HIV infection in Victoria: an analysis of surveillance data.

OBJECTIVES: To describe the epidemiology of HIV in Victoria between 1997 and 2002 using HIV surveillance data. METHODS: All HIV diagnoses notified to the Victorian HIV Registry from 1997 to 2002 were described. RESULTS: The average annual number of HIV notifications rose from 160 during 1997-99 to 216 during 2000-02, with the number of infections from men who have sex with men (MSM) increasing by 41%. Notifications from MSM acquired from casual or anonymous partners increased from 65 in 1997-99 to 92 in 2000-02. Infections attributable to heterosexual contact increased from an average number of 30 during 1997-99 to 46 during 2000-02, a 53% increase. CONCLUSIONS: This rise in HIV notifications in Victoria threatens this State's progress in controlling the HIV epidemic. IMPLICATIONS: The surveillance data demonstrate a need to implement effective, innovative and evidence-based programs for HIV prevention.

Referral patterns for gynaecological radiotherapy in Victoria.

A retrospective chart review was undertaken on all patients in Victoria who were referred for radiotherapy for a gynaecological cancer from February 1997 to January, 1998. Three hundred and ten patients were identified which represents less than one-third of all gynaecological cancers diagnosed in Victoria each year. Ninety-two of the 310 patients (30%) referred for radiotherapy were managed without the prior involvement of a certified gynaecological oncologist. The 310 patients included 95 patients with cervical cancer, 33 patients with ovarian cancer and 142 patients with endometrial cancer. The initial management strategies employed for patients with the major gynaecological cancers varied depending on the source of referral. This difference was most marked in endometrial cancer due mainly to differing indications for full surgical staging and subsequent referral for radiotherapy both between types of specialists and also between gynaecological oncology units. The development of evidence based guidelines in the major gynaecological cancers should lead to a more uniform approach to the care of women with gynaecological malignancies.

Epidemiology of an avian influenza outbreak in Victoria in 1985.

In May 1985 an outbreak of avian influenza, a disease exotic to the Australian poultry industry, occurred on a farm in central Victoria. The outbreak was contained on that farm by immediate depopulation and disinfection measures. A description of the epidemiology of the outbreak was made during and after the event by interviewing involved personnel and by an extensive sampling and surveillance program both on the affected farm and across Victoria. Although the origin of the infection was not established, it is considered most likely that wild birds introduced the virus. The infection status of wild bird populations in the area has not been ascertained but sampling surveys of the poultry industry indicated that there were no other infected flocks in the state. The infection may have entered the affected flock as long as 2 weeks prior to the clinical outbreak although the exact timing could not be ascertained. The spread of disease on the farm appeared to be largely due to humans acting as mechanical vectors.

Economic evaluation of a pit and fissure dental sealant and fluoride mouthrinsing program in two nonfluoridated regions of Victoria, Australia.

OBJECTIVES: This study assessed the cost effectiveness of a three-year school-based pit and fissure dental sealant and fluoride mouthrinsing program in two nonfluoridated regions in Victoria, Australia. METHODS: The analysis was based on a community intervention in five schools comparing an intervention group receiving the pit and fissure dental sealant, a weekly fluoride mouthrinsing, and an annual oral hygiene education session, with a control group receiving oral hygiene education only. The study measured mean differences in DMFS increments between study groups. RESULTS: The mean discounted DMFS difference in increment (DMFS avoided) between study groups was 1.22 DMFS over three years. The incremental cost-effectiveness ratio comparing intervention to control group varied between a net savings of $7.00 to a cost of $35.60 per DMFS avoided, depending on assumptions used in the analysis. Results were sensitive to assumptions on program effectiveness, dental examination rates, and baseline DMFS of students. The program became more cost effective with each successive year of the program. CONCLUSIONS: The introduction of such a preventive program in nonfluoridated regions of Victoria will represent an efficient use of community resources. Policy issues that need consideration include whether to target areas where adolescents have a history of high dental disease experience, and whether dentists or auxiliaries are used as service providers. The need exists for a systematic evaluation (including an economic evaluation component) of dental prevention and treatment programs in Australia.

Regulating the construction of hospitals or vice versa: the courts and private hospital planning in Victoria.

This paper examines the legal framework for regulating the development of new private hospitals in Victoria. It first reviews the genesis of the statutory power for private hospital regulation and outlines the two court cases which clarified the interpretation of the statute. The legislation and its interpretation by the courts emphasise a particular approach to private hospital planning which does not necessarily address the problems faced by consumers of hospital services in Victoria. It is argued that the law has constructed a particular framework for private hospital regulation which does not address the critical problems facing the hospital system in the 1990s. The legal framework for regulation is based on property rights rather than the needs of hospital users, despite the language used in the legislation.

An evaluation of a campaign to increase cervical cancer screening in rural Victoria.

This paper reports on the second of four regionally-based campaigns co-ordinated in rural Victoria by the Anti-Cancer Council of Victoria. The campaign encompassed community-based activities, general practitioner involvement and screening clinics. The impact of the campaign on Pap test rates and on the profile of women whose tests were reported by the Victorian Cytology Gynaecological Service is examined. We conclude that the campaign was successful in achieving its primary objective of attracting older and relatively underscreened women into having a Pap test. The special screening clinics were considered particularly effective in reaching women in the target audience. As a result of this campaign, new initiatives, were incorporated into subsequent programs.

Legislation for school entry immunisation certificates in Victoria.

In 1982 the National Health and Medical Research Council recommended that every state introduce legislation requiring immunisation certificates at school entry. Victoria was the first state to enact such legislation. This paper explores the process and difficulties encountered in achieving this legal requirement, describes the requirements under the legislation as it was finally introduced, and examines the early data available to the state health department regarding its implementation. Compliance with the legislation and immunisation status of children enrolling in government primary schools were ascertained from mid-year census data. In 1992 almost 90 per cent of children complied with the legislation, but because 10.2 per cent of children did not present a certificate it was possible to estimate only the lower limit of statewide coverage at 85 per cent against the prescribed diseases. School entry immunisation legislation may provide an important safety net to identify children with incomplete immunisation. However, the effectiveness of the legislation in Victoria remains unproven, and the requirements of the legislation are demanding for parents, local councils, and schools. The failure to document immunisation status in over 10 per cent of children indicates that further efforts to increase compliance are needed. This will require information on the vaccination status of those without certificates and the reasons they have not complied. The impact of the legislation needs further evaluation, although it may be years before its effectiveness can be gauged. Its effectiveness may depend upon enforcement of the requirement to exclude unimmunised children in disease outbreaks.

An evaluation of school entry immunisation certificates in Victoria.

We evaluated legislation introduced into Victoria in 1991 requiring that all children enrolling in primary school certify their immunisation status. Information was requested from all local councils. All primary schools in two local government areas were followed up, providing an indication of the validity of the analysis obtained from data collected during the mid-year census. From 166 of 210 local councils in Victoria, 48,422 documents relating to school entry immunisation certificates were issued for children entering their preparatory year. At least 522 children were enrolled in school on an undertaking to complete immunisation, and were likely to have had their immunisation completed as a result of the legislation. Only 170 statutory declarations of conscientious objection to immunisation were made, indicating that few parents are willing to express firm anti-vaccine sentiments. Compliance with the immunisation certificate legislation is overestimated by the mid-year census because many schools have accepted nonstatutory evidence of immunisation. Mobile and immigrant families find it particularly difficult to achieve certification. Local councils are inconsistent in the way in which they issue certificates. Further follow-up and feedback is essential to better inform schools and parents about the legislation. Such follow-up can improve the certification rates of children then and in subsequent years. The legislation has imposed a considerable workload on councils, but without efforts to improve compliance with the legislation and to develop practical guidelines for documentation of immunisation and appropriate guidelines regarding transfer, many inadequately immunised children may remain at risk from vaccine-preventable diseases.

Injury morbidity in Victoria among adults 25 to 64 years of age: implications for prevention.

The aim of this retrospective study was to complete the baseline descriptive epidemiology of hospital-treated injury for all ages in Victoria, by focusing on the age group, 25 to 64 years, to identify major categories of injury and the potential for prevention. We analysed injury databases for hospital admissions and emergency department presentations for major variables influencing injury frequency and rates. We found that nearly 40 per cent (158 537) of all hospitalisations for injury occurred in the study age range. The major causes of injury were health-care related causes (32 per cent), falls (15 per cent), transport (14 per cent), and intentional causes (10 per cent). The leading reason for emergency department presentation (excluding admission) was unintentional cutting or piercing injury. The home was the major location of injury. Vehicles, man-made and natural surfaces, knives, and floors and flooring materials were among the leading five factors potentially associated with both admissions and presentations. Injury prevention in this age range will be largely addressed by the injury-prevention strategy being implemented in Victoria. However, specific additional issues were identified, including falls from ladders and scaffolds, pedestrian and female passenger injury, and injury associated with power tools, chain saws, and knives.

A profile of HIV testing in Victoria to the end of 1993. Victorian Collaborative Group on HIV and AIDS Surveillance (VCGHAS).

Examination of testing patterns for human immunodeficiency virus (HIV) in a population is important because it affects interpretation of surveillance data on new HIV diagnoses and can guide the targeting and evaluation of campaigns to encourage appropriate antibody testing. This report describes a relatively inexpensive mechanism of collecting information on who is being tested for HIV in Victoria (other than at the Blood Bank). The annual number of HIV tests performed in Victoria increased steadily throughout the 1980s but the rate of increase slowed in the early 1990s. By 1993, women accounted for almost half of HIV tests, although they made up only 8 per cent of positive tests. There were marked differences in the volume of testing and testing profiles of different laboratories. The information available on personal risk category and the reasons for HIV tests show that many people of low risk are tested, although conclusions are limited by inadequate information elicited or provided by many requesting doctors. For better information on what is occurring with respect to HIV testing, the fundamental requirement is better compliance from requesting doctors in supplying basic information on who they test and why.

Survey of dental practice/dental education in Victoria. Part IV. Specialist dental practice.

A survey of dentists registered with the Dental Board and resident in the State of Victoria included two sections, one for specialist/restricted practitioners and the other for practitioners, who had gained a postgraduate degree from the University of Melbourne between December 1982 and 1987. The responses of the former suggested that demand for most specialist services appears to be reasonably healthy at the moment and the majority of the latter indicated that they had been adequately trained for specialist practice. It was suggested that there are several market forces which could influence the number of applicants seeking specialist training in future. Strongest demand was likely to be sustained for oral surgery and orthodontics. This is despite evidence of a decline in demand for specialist orthodontic services in private practice. Attention was drawn to the 1986 Ministerial Review of Dental Services in Victoria, in which concern was expressed for the lack of access to orthodontic services for low income families. It was proposed that more cost-effective methods of deploying orthodontic personnel could be used, as in other countries, to provide this access. Demand for specialist services in endodontics, paediatric dentistry, periodontics and prosthodontics could decline in future as general practitioners steadily broaden their range of services through continuing education courses.

Factors influencing recent dental graduates' location and sector of employment in Victoria.

BACKGROUND: Recruitment and retention of dentists in the public sector and rural areas in Victoria has become increasingly difficult in recent years. There are little available data on the factors that influence the sector and location of practice of new dental graduates. The objective of this study was to investigate the factors considered by new graduates in determining the location and sector of employment after graduation, and influencing any early changes in career path. METHODS: Questionnaires were sent to dentists who Mgraduated from The Univrersity of Melbourne from graduated from The University of Melbourne from 2000-2003 who were currently practising in Victoria. There were 154 subjects to whom questionnaires were sent and 109 useable questionnaires were returned, a response rate of 74 per cent. RESULTS: Upon graduation, 53 per cent of the new graduates chose to work in the private sector only, compared to 15 per cent in public sector only and 33 per cent in both. At present, 71 per cent work in the private sector only, 17 per cent in the public sector only and 12 per cent in both. The most important factors for choosing to work in the private sector were receiving broad range of clinical experience, opportunities to familiarize with practice management and providing a continuity of care. The principal factors for practising in the public sector were clinical mentoring and advice, consolidating clinical skills and work environment. Initially, 48 per cent of the sample chose to work in metropolitan areas only, 39 per cent in rural areas only and 13 per cent in both. Factors that influenced the decision to work in rural areas were the broad range of clinical experience and remuneration, while the main factors for choosing to work in metropolitan areas were lifestyle and proximity to family and friends. CONCLUSIONS: This study found that a large proportion of new dental graduates initially chose to work in the public sector and rural areas on graduation primarily as a means of consolidating their clinical skills. However, retention of dentists in both these areas appears to be a problem, with less than 10 per cent of 2000-2001 graduates still than 10 per cent of 2000-2001 graduates still working in the public sector and only 20 per cent of 2000-2001 graduates still working in rural areas.

Epidemiology of pterygium in Victoria, Australia.

AIM: To describe the prevalence of and risk factors for pterygium in a population based sample of residents of the Australian state of Victoria who were aged 40 years and older. METHODS: The strata comprised nine randomly selected clusters from the Melbourne statistical division, 14 nursing homes randomly selected from the nursing homes within a 5 kilometre radius of the nine Melbourne clusters, and four randomly selected clusters from rural Victoria. Pterygium was measured in millimetres from the tip to the middle of the base. During an interview, people were queried about previous ocular surgery, including surgical removal of pterygium, and their lifetime exposure to sunlight. RESULTS: 5147 people participated. They ranged in age from 40 to 101 years and 2850 (55.4%) were female. Only one person in the Melbourne cohort reported previous pterygium surgery, and seven rural residents reported previous surgery; this information was unavailable for the nursing home residents. Pterygium was present upon clinical examination in 39 (1.2%) of the 3229 Melbourne residents who had the clinical examination, six (1. 7%) of the nursing home residents, and 96 (6.7%) of the rural residents. The overall weighted population rate in the population was 2.83% (95% CL 2.35, 3.31). The independent risk factors for pterygium were found to be age (OR=1.23, 95% CL=1.06, 1.44), male sex (OR=2.02, 95% CL=1.35, 3.03), rural residence (OR=5.28, 95% CL=3. 56, 7.84), and lifetime ocular sun exposure (OR=1.63, 95% CL=1.18, 2. 25). The attributable risk of sunlight and pterygium was 43.6% (95% CL=42.7, 44.6). The result was the same when ocular UV-B exposure was substituted in the model for broad band sun exposure. CONCLUSION: Pterygium is a significant public health problem in rural areas, primarily as a result of ocular sun exposure.

Unintentional poisoning hospitalisations among young children in Victoria.

OBJECTIVES: To describe the epidemiology of unintentional childhood poisoning hospitalisation in Victoria, Australia, in order to monitor trends and identify areas for research and prevention. METHODS: For children under 5 years, all Victorian public hospital admissions, July 1987 to June 1995, due to unintentional poisoning by drugs, medicines, and other substances were analysed. Similar cases were also extracted from the database of the Royal Children's Hospital intensive care unit, Melbourne for the years 1979-91. Log linear regression modelling was used for trend analyses. RESULTS: The annual average childhood unintentional poisoning rate was 210.7 per 100,000. Annual rates for males consistently exceeded those for females. The most common agents were those acting on the respiratory system and on smooth and skeletal muscles (muscle relaxants, cough and cold medicines, antiasthmatics), aromatic analgesics (paracetamol), and systemic agents (including antihistamines). Further investigation is justified for cardiac agents, some respiratory agents, and asthma medications. CONCLUSIONS: Childhood poisoning hospitalisation rates have not decreased in Victoria over recent years. A focused, agent specific approach, as well as a series of generic measures for the prevention of poisoning to children under 5 is advocated. The ongoing surveillance, collection and analysis of data, in addition to research on specific poisoning agents are essential components of any prevention strategy.

Sexually transmissible diseases--knowledge and practices of general practitioners in Victoria, Australia.

OBJECTIVE: To examine knowledge and practices in relation to sexually transmissible diseases (STDs) of general practitioners (GPs) in Victoria, Australia. METHOD: A questionnaire was distributed to 520 Victorian GPs randomly selected from the Australian Medical Publishing Company (AMPCo) database of Australian medical practitioners. RESULTS: A response rate of 85% was obtained. While sexual health consultations were common for Victorian GPs, STD caseloads were generally low. Knowledge of clinical features of symptomatic STDs and of important STD epidemiology was generally good although there was a lower awareness of the asymptomatic nature of the most prevalent STDs in Victoria. Diagnostic tests were generally selected appropriately although many GPs did not perform the gold standard combination of tests required for adequate differential diagnosis. Level of STD STD knowledge was related to frequency of advising about safe sex, diagnosing STDs, and younger practitioner age. Attendance at any of a number of postgraduate courses of relevance to the management of STDs was not related to better STD knowledge overall. CONCLUSIONS: Prevention and detection of STDs in general practice involve risk assessment and screening of asymptomatic patients as well as effective treatment of symptomatic patients and their contacts. Results presented here suggest that GPs have good knowledge and use appropriate investigations for patients presenting with symptoms of an STD. The low levels of awareness of the asymptomatic nature of many STDs and other particular aspects of STD knowledge and practice should be addressed in undergraduate and postgraduate medical education programmes.

Attitudes to taking a sexual history in general practice in Victoria, Australia.

OBJECTIVE: To examine general practitioners' (GPs') attitudes towards taking a sexual history. METHODS: Questions on sexual history taking were included in a random survey on the STD knowledge, attitudes, and practices of 600 GPs practising in Victoria, Australia. RESULTS: Most GPs commonly asked patients about safe sex (79%), number of sex partners (63%), and injecting drug use (60%) while fewer asked about recent overseas travel (50%) and sex with sex workers (31%). GPs who performed sexual health consultations daily or weekly identified barriers to sexual history taking to be of less concern than those who performed such consultations infrequently. Most GPs (92%) would take a sexual history from a man presenting as the sexual contact of an infected partner, but less than a third would do so for a patient routinely requesting the contraceptive pill (28%), a Papanicolaou (Pap) smear (30%), or advice about immunisation before overseas travel (30%). Female GPs were significantly more likely than male GPs to take a sexual history in those clinical situations involving a female patient and also to perceive these patients as experiencing less embarrassment. CONCLUSIONS: This study highlights both the lack of opportunistic sexual history taking and the main barriers to sexual history taking in general practice in Victoria, Australia. The importance of educating both patients and GPs about sexual history taking are discussed.

Prevalence of substance use and delinquent behavior in adolescents from Victoria, Australia and Washington State, United States.

This article compares prevalence estimates of substance use and delinquent behavior in Washington State, United States and Victoria, Australia, two states chosen for their different policy environments around problem behavior. Few comparisons of international differences on rates of multiple problem behavior exist, and most are based on methods that are not matched, raising the question of whether findings are based on methodological differences rather than actual rate differences. The International Youth Development Study used standardized methods to recruit and administer an adaptation of the Communities That Care Youth Survey to representative state samples of fifth-, seventh-, and ninth-grade students in each state. Rates of delinquent behavior were generally comparable. However, striking differences in substance use were noted, with Victoria students reporting higher rates of alcohol use, alcohol misuse, smoking, and inhalant use, whereas Washington State students reported higher rates of marijuana use. Implications for conducting international comparisons are discussed.

An evaluation of the telepsychiatry programme in Victoria, Australia.

We evaluated the use of telepsychiatry in Victoria, a state of Australia with some five million people. There were 39 sites at the time of the survey, 12 metropolitan and 27 rural. Interviews and postal questionnaires were used. A total of 99 staff were surveyed, 69 by post and 30 during visits. There were 37 participants from metropolitan sites and 62 from rural sites. Rural sites conducted an estimated 137 sessions per month (i.e. an average of 5.1 per month per site). The majority (70%) of the usage in Victoria was for clinical purposes, both primary and secondary consultations.
