RESUMO
OBJECTIVES: To determine the mean, median and 10th and 90th percentile levels of fees and out-of-pocket costs to the patient for an initial consultation with a consultant physician; to determine any differences in fees and bulk-billing rates between specialties and between states and territories. DESIGN, PARTICIPANTS AND SETTING: Analysis of 2015 Medicare claims data for an initial outpatient appointment with a consultant physician (Item 110) in 11 medical specialties representative of common adult non-surgical medical care (cardiology, endocrinology, gastroenterology, geriatric medicine, haematology, immunology/allergy, medical oncology, nephrology, neurology, respiratory medicine and rheumatology). MAIN OUTCOME MEASURES: Mean, median, 10th and 90th percentile levels for consultant physician fees and out-of-pocket costs, by medical specialty and state or territory; bulk-billing rate, by medical specialty and state/territory. RESULTS: Bulk-billing rates varied between specialties, with only haematology and medical oncology bulk-billing more than half of initial consultations. Bulk-billing rates also varied between states and territories, with rates in the Northern Territory (76%) nearly double those elsewhere. Most private consultations require a significant out-of-pocket payment by the patient, and these payments varied more than fivefold in some specialties. CONCLUSION: Without data on quality of care in private outpatient services, the rationale for the marked variations in fees within specialties is unknown. As insurers are prohibited from providing cover for the costs of outpatient care, the impact of out-of-pocket payments on access to private specialist care is unknown.

Objective The aims of the present study were to determine the actual availability of private general paediatric appointments in the Melbourne metropolitan region for children with non-urgent chronic illnesses and the cost of such care. Methods A 'secret shopper' method was used. Telephone calls were made to a random sample of 47 private paediatric clinics. A trained research assistant posed as a parent, requesting the first available appointment with a specific paediatrician. Data regarding appointment availability, total potential charges and net charges after the Medicare rebate were collected. Results Appointments were available in 79% (n=37) of clinics, with 72% (n=34) able to offer an appointment with the requested general paediatrician. The number of days until available appointments varied from same day appointments to a wait of 124 days, with an average wait of 33 days. Of practices that provided information about the appointment cost (n=42), five bulk-billed for the consultation, whereas the remainder (n=37) were fee-paying clinics. The potential maximum charge for an initial consultation in the fee-paying clinics ranged from A$177 to A$430, with an average cost of A$279. The potential maximum out-of-pocket cost for patients ranged from A$40 to A$222, with an average out-of-pocket cost of A$128. Conclusions Private paediatric care in the Melbourne metropolitan region is generally available. The out-of-pocket cost of private paediatric out-patient care may present a potential economic barrier for some families. What is known about the topic? In Australia, out-of-pocket expenses for private specialist care are not covered by private health insurance. There are no data available on the actual cost of private paediatric consultations that are based on real-time assessments. Data collected in 1998 suggested that the average waiting time for a first standard consultation with a general paediatrician in a private room was 14.1 days. There are no recent empirical data on appointment availability and waiting time for appointments with general paediatricians in Australia. What does this paper add? There is high availability of paediatric consultations in the private sector. Waiting times for an appointment vary considerably from same day appointments to a wait of 124 days, with an average wait of 33 days. The cost of a private paediatric consultation in Australia to the patient is considerable, with an average potential maximum up-front charge for an initial consultation of A$279 and an average potential maximum out-of-pocket cost of A$128. What are the implications for practitioners? Data on the availability and cost of private paediatric consultations are imperative to formulate evidence-informed policy and better understand variations in the availability of public and private care.

Objective National health workforce data are used in workforce projections, policy and planning. If data to measure the current effective clinical medical workforce are not consistent, accurate and reliable, policy options pursued may not be aligned with Australia's actual needs. The aim of the present study was to identify any inconsistencies and contradictions in the numerical count of paediatric specialists in Australia, and discuss issues related to the accuracy of collection and analysis of medical workforce data. Methods This study compared respected national data sources regarding the number of medical practitioners in eight fields of paediatric speciality medical (non-surgical) practice. It also counted the number of doctors listed on the websites of speciality paediatric hospitals and clinics as practicing in these eight fields. Results Counts of medical practitioners varied markedly for all specialties across the data sources examined. In some fields examined, the range of variability across data sources exceeded 450%. Conclusions The national datasets currently available from federal and speciality sources do not provide consistent or reliable counts of the number of medical practitioners. The lack of an adequate baseline for the workforce prevents accurate predictions of future needs to provide the best possible care of children in Australia. What is known about the topic? Various national data sources contain counts of the number of medical practitioners in Australia. These data are used in health workforce projections, policy and planning. What does this paper add? The present study found that the current data sources do not provide consistent or reliable counts of the number of practitioners in eight selected fields of paediatric speciality practice. There are several potential issues in the way workforce data are collected or analysed that cause the variation between sources to occur. What are the implications for practitioners? Without accurate data on which to base decision making, policy options may not be aligned with the actual needs of children with various medical needs, in various geographic areas or the nation as a whole.

BACKGROUND: Children in Australia are infrequent recipients of general practitioner (GP) home visits. OBJECTIVE: The objective of this article is to examine whether parents who brought their child to an emergency department (ED) for a lower urgency condition had contacted a home-visiting GP prior to arriving at the ED. METHODS: Electronic surveys were completed by 1150 parents of children aged ≤9 years presenting with lower urgency conditions (triage category 4 or 5) to the EDs of four hospitals in metropolitan Melbourne. RESULTS: Only 83 (7%) parents had attempted to contact a home-visiting GP service and only 26 received a visit. Half of those who did receive a visit, and more than half who did not, reported being told to attend the ED by the service. DISCUSSION: There is infrequent use of home-visiting GP services by children who present to EDs with lower urgency conditions. These services refer some children with low-urgency conditions to the ED.

OBJECTIVE: To determine actual availability and cost of general practitioner appointments for children with conditions of low acuity and low urgency, from the perspective of the child's family. DESIGN, PARTICIPANTS AND SETTING: A "secret shopper" method, whereby research assistants posing as parents seeking appointments for mildly ill children telephoned a random sample of 225 general practice clinics within three Melbourne Medicare Local catchments, which included urban, suburban and regional areas; the study was conducted between 1 August and 30 September 2014. MAIN OUTCOME MEASURES: Availability of same-day appointments and time until appointment; bulk-billing status of the clinic and/or the potential cost of an appointment. RESULTS: High availability of appointments was found in all three catchment areas (range, 72%-81% of clinics contacted). About half (49%) had appointments available within 4 hours. Between 72% and 80% of clinics contacted in the three Medicare Local catchment areas offered bulk-billing for paediatric appointments. CONCLUSION: There is extensive same-day new-patient GP appointment availability for mildly ill children in the catchment areas of Melbourne studied. Further, as most of the available appointments are in clinics that bulk bill, financial access should not affect this availability. Increased paediatric presentations to emergency departments are not likely to be the result of limited GP availability. These findings provide an important base for developing data-driven policy approaches to the development and use of primary care.

OBJECTIVE AND DESIGN: Individuals seeking treatment for chronic pain in multidisciplinary pain management services are typically already on high doses of pain medications. This cross-sectional cohort study of patients with long-term chronic pain examined profiles of polypharmacy and pain medication-related harm exposure. SETTING: Multidisciplinary pain management service. SUBJECTS: The cohort comprised 224 patients taking medications for their pain (1-9 medications; mean = 3.19) with an average pain duration of 10.33 years. METHODS: The Medication Quantification Scale III (MQS-III) was used to examine potential harm exposure. We generated detriment scores for simple analgesics, adjunctive therapies (e.g., anticonvulsants), opioids, and benzodiazepines. RESULTS: The total MQS-III score was correlated with the total number of medications, but not with age. Almost 10% of patients took medications from all four categories, with most taking medications from two (37%) to three (35%) classes. Eighty percent of patients were taking opioids, accounting for 41% of total MQS scores. Five primary profiles of potential medication-related harms were identified: high harm from all medication categories (N = 12); above average harm from single category-simple analgesics (N = 76), adjunctive analgesics (N = 59), or opioids (N = 46); and above average opioid and benzodiazepine harm (N = 31). CONCLUSIONS: While treatment with multiple medications for synergistic or adjunctive effects may assist in medical management of chronic pain, this approach generates increased potential harm exposure. We show that the majority of detriment comes from medications other than opioids and highlight the importance of profiling all pain medications contributing to polypharmacy in clinical pain studies.

BACKGROUND: Co-payments for medical services have been a controversial topic in Australia. OBJECTIVE: The aim of this study was to assess parents' perspectives on the potential impact of co-payments for general practice and emergency department (ED) services for children. METHODS: A cross-sectional survey was conducted between May and November 2014 in the EDs of four metropolitan hospitals in Melbourne. The participants were 1531 parents of children presenting with lower urgency conditions. The outcome measures were the potential impact of a $7 general practice co-payment or a $7 ED co-payment on the use of services for children. RESULTS: Seventy-three per cent (n = 1089) of parents reported that a $7 general practice co-payment would not increase their use of EDs for lower urgency problems for their children. Increased use was associated with younger parent or guardian age and lower household income. Ninety per cent (n = 1343) reported that a $7 ED co-payment would not have an impact on ED attendance. Impact was associated with younger parent or guardian age and lower income. DISCUSSION: For most parents presenting to an ED with their child, a $7 general practice or ED co-payment is unlikely to affect health service use, although significant differences in response were found according to parent or guardian age and household income.

INTRODUCTION: There is recognition among public health scholars and community practitioners that translating cancer prevention and control research into practice is challenging. This circumstance is particularly germane to medically underserved communities, such as rural Appalachia, where few evidence-based interventions originate and cancer incidence and mortality are elevated. METHODS: A case study approach was selected to examine the collective experience of 13 West Virginia community organizations awarded mini-grants requiring the use of an evidence-based cancer control intervention. Methods included a systematic review of grant applications and final programmatic reports, a faxed survey, and qualitative, in-depth interviews with key stakeholders. RESULTS: Appalachian grantees reported notable challenges with selecting, adapting, and implementing evidence-based cancer education interventions. Evidence-based programming was viewed as a barrier. Grantees made a range of adaptations to meet constituent needs, thereby jeopardizing intervention fidelity. However, programs were perceived as successful due to community participation and engagement, some element of behavioral change, dissemination of the health message, and establishment of collaborative partnerships. CONCLUSIONS: A descriptive examination provides insights into the challenges of translating research to practice. This Appalachian cancer education grant program also highlights areas of compromise that are important for researchers and practitioners to understand.

Objective The aim of this study was to determine the revenue to consultant physicians for private out-patient consultations. Specifically, the study determined changing patterns in revenue from 2011 to 2015 after accounting for bulk-billing rates, changes in gap fees and inflation. Methods An analysis was performed of consultant physician Medicare claims data from 2011 to 2015 for initial (Item 110) and subsequent (Item 116) consultations and, for patients with multiple morbidities, initial management planning (Item 132) and review consultations (Item 133). The analysis included 12 medical specialties representative of common adult non-surgical medical care. Revenue to consultant physicians was calculated for initial consultations (Item 110: standard; Item 132: complex) and subsequent consultations (Item 116: standard; Item 133: complex) accounting for bulk-billing rates, changes in gap fees and inflation. Results From 2011 to 2015, there was a decrease in inflation-adjusted revenue from standard initial and subsequent consultations (mean -$2.69 and -$1.03 respectively). Accounting for an increase in the use of item codes for complex consultations over the same time period, overall revenue from initial consultations increased (mean +$2.30) and overall revenue from subsequent consultations decreased slightly (mean -$0.28). All values reported are in Australian dollars. Conclusions The effect of the multiyear Medicare freeze on consultant physician revenue has been partially offset by changes in billing practices. What is known about the topic? There was a 'freeze' on Medicare schedule fees for consultations from November 2012 to July 2018. Concerns were expressed that the schedule has not kept pace with inflation and does not represent appropriate payments to physicians. What does this paper add? Accounting for bulk-billing, changes in gap fees and inflation, revenue from standard initial and subsequent consultations decreased from 2011 to 2015. Use of item codes for complex consultations (which have associated higher schedule fees) increased from 2011 to 2015. When standard and complex consultation codes are analysed together (and accounting for bulk-billing, changes in gap fees and inflation), revenue from initial consultations increased and revenue from subsequent consultations decreased slightly. What are the implications for practitioners? Efforts to control government expenditure through Medicare rebate payment freezes may result in unintended consequences. Although there were no overall decreases in bulk-billing rates, the shift to higher-rebate consultations was noticeable.

Objectives To determine national service usage for initial and subsequent outpatient consultations with a consultant physician and any variation in service-use patterns between states and territories relative to population. Methods An analysis was conducted of consultant physician Medicare claims data from the year 2014 for an initial (item 110) and subsequent consultation (item 116) and, for patients with multiple morbidities, initial management planning (item 132) and review (133). The analysis included 12 medical specialties representative of common adult non-surgical medical care (cardiology, endocrinology, gastroenterology, general medicine, geriatric medicine, haematology, immunology and allergy, medical oncology, nephrology, neurology, respiratory medicine and rheumatology). Main outcome measures were per-capita service use by medical speciality and by state and territory and ratio of subsequent consultations to initial consultations by medical speciality and by state and territory. Results There was marked variation in per-capita consultant physician service use across the states and territories, tending higher than average in New South Wales and Victoria, and lower than average in the Northern Territory. There was variation between and within specialties across states and territories in the ratio of subsequent consultations to initial consultations. Conclusion Significant per-capita variation in consultant physician utilisation is occurring across Australia. Future studies should explore the variation in greater detail to discern whether workforce issues, access or economic barriers to care, or the possibility of over- or under-servicing in certain geographic areas is leading to this variation. What is known about the topic? There are nearly 11million initial and subsequent consultant physician consultations billed to Medicare per year, incurring nearly A$850million in Medicare benefits. Little attention has been paid to per-capita variation in rates of consultant physician service use across states and territories. What does this paper add? There is marked variation in per-capita consultant physician service use across different states and territories both within and between specialties. What are the implications for practitioners? Variation in service use may be due to limitations in the healthcare workforce, access or economic barriers, or systematic over- or under-servicing. The clinical appropriateness of repeated follow-up consultations is unclear.

OBJECTIVE: To determine: 1) the mean, median and range of fees for initial and subsequent private outpatient consultations with a general paediatrician in Australia; 2) any variation in fees and bulk billing rates between states/territories; and 3) volume of outpatient general paediatric specialist consultations relative to child population. METHODS: Analysis of Medicare claims data from the years 2011 and 2014 for initial consultations (items 110 and 132), subsequent consultations (items 116 and 133), and autism or pervasive developmental disorder (PDD) initial consultation (item 135) with a general paediatrician. RESULTS: Fees for initial and subsequent general paediatric outpatient consultations varied within, and between, states and territories. Fees increased slightly from 2011 to 2014, after accounting for inflation. The volume of consultations relative to child population varied markedly across states and territories, as did bulk billing rates. Use of item codes for patients with multiple morbidities (132 and 133) increased significantly from 2011 to 2014. Autism/PDD consultation service use (item 135) and fees remained relatively stable. CONCLUSIONS: There was variation in service use, fees and bulk billing within, and between, states and territories, and across time and consultation types. Implications for public health: Future studies should assess the impact of such variation on access to paediatric services and the relationship, if any, to variation in state investment in public paediatric outpatient services.

Neuroscientific explanations of gambling disorder can help people make sense of their experiences and guide the development of psychosocial interventions. However, the societal perceptions and implications of these explanations are not always clear or helpful. Two workshops in 2013 and 2014 brought together multidisciplinary researchers aiming to improve the clinical and policy-related effects of neuroscience research on gambling. The workshops revealed that neuroscience can be used to improve identification of the dangers of products used in gambling. Additionally, there was optimism associated with the diagnostic and prognostic uses of neuroscience in problem gambling and the provision of novel tools (eg, virtual reality) to assess the effectiveness of new policy interventions before their implementation. Other messages from these workshops were that neuroscientific models of decision making could provide a strong rationale for precommitment strategies and that interdisciplinary collaborations are needed to reduce the harms of gambling.

OBJECTIVE: The age band with, by far, the greatest number of ED presentations is children 0-4 years, with other paediatric age bands also among the highest. As the majority of these presentations are for lower urgency conditions, we sought to determine why parents seek ED care for their child for lower urgency conditions. METHODS: A survey study of 1150 parents or guardians of children with lower urgency conditions (triage category 4 or 5) presenting to the EDs of three public general and one paediatric specialty hospital in metropolitan Melbourne. RESULTS: Fewer than half of parents (43%) attempted to make an appointment with a general practitioner (GP) for their child prior to presenting to the ED. Two-thirds of those who did contact a GP were instructed by their GP to go to the ED for their lower urgency condition. Few attempted to contact a nurse telephone triage service or after-hours GP service. CONCLUSIONS: The current magnitude and the growth of lower urgency paediatric ED presentations is a strain on the health care system. Efforts to educate parents regarding the suitability and availability of GP appointments can be the cornerstone of an initial strategy to address this issue. However, efforts to address the high rates of GP referral to EDs for low urgency presentations will be more vexing to develop, yet no less important. They will require addressing fundamental issues in both current GP care for children and the training of GP registrars.

OBJECTIVE: To determine the accuracy and reliability of triage of children in public hospital EDs using the Australasian Triage Scale (ATS). This is the first study to examine these issues in paediatric triage following the 2007 development of the Emergency Triage Education Kit (ETEK) to foster accurate and consistent application of the ATS. METHODS: A convenience sample of 167 triage nurses working at three general hospitals and one speciality paediatric hospital in greater metropolitan Melbourne assigned triage ratings for nine paediatric clinical scenarios using the ATS. Scenarios were derived from the ETEK or from other published sources. Kappa was used to assess interrater reliability within and between hospitals. RESULTS: Triage nurses correctly assigned triage scores to an average of 5.3 of nine paediatric clinical scenarios. Accuracy in specific hospitals ranged from a low of 15% on one scenario, to 100% accuracy on a different scenario at a different hospital. Interrater reliability within and across the EDs studied was found to be kappa = 0.27. Both accuracy and interrater reliability were marginally higher at the speciality paediatric hospital. CONCLUSIONS: Our findings demonstrate inconsistencies in the accuracy and reliability in which sick children presenting to EDs receive triage scores both within and across hospitals. These results suggest the need for improvements either in current triage nurse training or training resources. Use of the ETEK alone has not resulted in high levels of paediatric triage accuracy or reliability.

Researchers have found a consistent relationship between a number of diseases, including diabetes, heart disease, high blood pressure and stroke. Although study results related to cancer have been conflicting, with some showing an increased risk and others not showing such an association, obesity does appear to increase the risk of cancers of the breast, colon, prostate, endometrium, cervix, ovary, kidney and gallbladder. Studies have also found an increased risk for cancers of the liver, pancreas, rectum and esophagus. Although there are many theories about how obesity increases cancer risk, the exact mechanisms are not known. They may be different for different types of cancer. In addition, because obesity develops through a complex interaction of heredity and lifestyle factors, researchers may not be able to tell whether the obesity or something else led to the development of cancer.

The appropriateness of applying drink driving legislation to motorcycle riding has been questioned as there may be fundamental differences in the effects of alcohol on driving and motorcycling. It has been suggested that alcohol may redirect riders' focus from higher-order cognitive skills such as cornering, judgement and hazard perception, to more physical skills such as maintaining balance. To test this hypothesis, the effects of low doses of alcohol on balance ability were investigated in a laboratory setting. The static balance of twenty experienced and twenty novice riders was measured while they performed either no secondary task, a visual (search) task, or a cognitive (arithmetic) task following the administration of alcohol (0%, 0.02%, and 0.05% BAC). Subjective ratings of intoxication and balance impairment increased in a dose-dependent manner in both novice and experienced motorcycle riders, while a BAC of 0.05%, but not 0.02%, was associated with impairments in static balance ability. This balance impairment was exacerbated when riders performed a cognitive, but not a visual, secondary task. Likewise, 0.05% BAC was associated with impairments in novice and experienced riders' performance of a cognitive, but not a visual, secondary task, suggesting that interactive processes underlie balance and cognitive task performance. There were no observed differences between novice vs. experienced riders on static balance and secondary task performance, either alone or in combination. Implications for road safety and future 'drink riding' policy considerations are discussed.
