Physician responses to insurance benefit restrictions: The case of ophthalmology.

This study examines the impact of social insurance benefit restrictions on physician behaviour, using ophthalmologists as a case study. We examine whether ophthalmologists use their market power to alter their fees and rebates across services to compensate for potential policy-induced income losses. The results show that ophthalmologists substantially reduced their fees and rebates for services directly targeted by the benefit restriction compared to other medical specialists' fees and rebates. There is also some evidence that they increased their fees for services that were not targeted. High-fee charging ophthalmologists exhibited larger fee and rebate responses while the low-fee charging group raise their rebates to match the reference price provided by the policy environment.

Preterm Birth and Total Health Care Use and Costs in the First 5 Years of Life: A Population-based Study.

OBJECTIVES: To investigate the relationship between preterm birth and hospital/out-of-hospital care and costs over the first 5 years of life. STUDY DESIGN: Birth data from a population-based cohort of 631 532 infants born between 2007 and 2013 were linked probabilistically with data on hospitalizations, primary and secondary care, and the use of medications. We analyzed the distribution of health care use and public health care costs for infants who survived at least 5 years, comparing the outcomes of extremely preterm (<28 weeks of gestation), very preterm (28-32 weeks), moderate to late preterm (32-37 weeks), and term infants (at least 37 weeks). A linear regression model was used to investigate the effect of preterm birth on these outcomes, controlling for important confounders including pregnancy and birth complications, neonatal morbidity, survival, and maternal socioeconomic characteristics. RESULTS: Preterm birth has a statistically significant and economically relevant effect on health care use and costs in the first 5 years of life. Compared with a term infant, preterm infants born at 32-36 weeks, 28-32 weeks, and <28 weeks of gestation had, respectively, an average of 7.0 (SE 0.06), 41.6 (0.18), and 68.7 (0.35) more hospital days; 3.1 (0.04), 11.0 (0.13), and 13.2 (0.25) more outpatient specialist physician visits; and 1.2-fold (<0.01), 6.8-fold (0.01), and 10.9-fold (0.02) higher 5-year public health care costs. Preterm infants also had statistically significantly higher levels of general practitioner visits and use of medications. CONCLUSIONS: Higher levels of accessible care are needed for preterm infants across health care settings and over sustained periods. As our understanding of the impact of preterm birth on long-term clinical outcomes continues to improve, clinicians and policymakers should develop an accurate recognition of these needs to enable appropriate resource allocation toward research priorities and early intervention strategies.

Geographic variation in out-of-pocket costs for radiation oncology services.

OBJECTIVES: To examine out-of-pocket costs incurred by patients for radiation oncology services and their variation by geographic location. DESIGN: Analysis of patient-level Medical Benefits Schedule (MBS) claims data linked with data from the Sax Institute 45 and Up Study. SETTING, PARTICIPANTS: People who received Medicare-subsidised radiation oncology services in New South Wales, 2006-2017. MAIN OUTCOME MEASURE: Mean out-of-pocket costs for an episode of radiation oncology (during 90 days from start of radiotherapy planning service), by geographic location (postcode-based), overall and after excluding episodes with no out-of-pocket costs (fully bulk-billed). RESULTS: During 2006-2017, 12 724 people received 15 506 episodes of radiation oncology care in 25 postcode-defined geographic areas. The proportion of episodes for which the out-of-pocket cost was less than $1 increased from 39% in 2006 to 76% in 2017; the proportion for which out-of-pocket costs exceeded $500 declined from 43% in 2006 to 10% in 2014, before increasing to 17% in 2017. For care episodes with non-zero out-of-pocket costs, the mean amount rose from around $1186 to $1611 per episode of care during 2006-2017. The proportion of radiation oncology episodes bulk-billed exceeded 90% in nine areas; in seven areas, all with exclusively private care provision of radiation oncology, it was 21% or smaller. Within geographic areas, out-of-pocket costs for individual care episodes varied widely; in ten areas with lower bulk-billing rates, the interquartile range for costs ranged from $240 to $1857. CONCLUSION: Out-of-pocket costs are an important determinant of access to care. Although radiotherapy costs for most people are moderate, some face very high costs, and these vary markedly by location. It is important to ensure that radiation oncology services remain affordable for all people who need treatment.

Fecal prevalence of Clostridium innocuum DNA in healthy horses and horses with colitis.

This study compared the prevalence of C. innocuum DNA in the feces of healthy horses and horses with acute colitis. C. innocuum was identified in 22% (15/68) of colitis cases and 18% (12/68) of healthy horses (p = 0.416).

Modelling the cost of place of birth: a pathway analysis.

BACKGROUND: In New South Wales (NSW), Australia there are three settings available for women at low risk of complications to give birth: home, birth centre and hospital. Between 2000 and 2012, 93.6% of babies were planned to be born in hospital, 6.0% in a birth centre and 0.4% at home. Availability of alternative birth settings is limited and the cost of providing birth at home or in a birth centre from the perspective of the health system is unknown. OBJECTIVES: The objective of this study was to model the cost of the trajectories of women who planned to give birth at home, in a birth centre or in a hospital from the public sector perspective. METHODS: This was a population-based study using linked datasets from NSW, Australia. Women included met the following selection criteria: 37-41 completed weeks of pregnancy, spontaneous onset of labour, and singleton pregnancy at low risk of complications. We used a decision tree framework to depict the trajectories of these women and Australian Refined-Diagnosis Related Groups (AR-DRGs) were applied to each trajectory to estimate the cost of birth. A scenario analysis was undertaken to model the cost for 30 000 women in one year. FINDINGS: 496 387 women were included in the dataset. Twelve potential outcome pathways were identified and each pathway was costed using AR-DRGs. An overall cost was also calculated by place of birth: $AUD4802 for homebirth, $AUD4979 for a birth centre birth and $AUD5463 for a hospital birth. CONCLUSION: The findings from this study provides some clarity into the financial saving of offering more options to women seeking an alternative to giving birth in hospital. Given the relatively lower rates of complex intervention and neonatal outcomes associated with women at low risk of complications, we can assume the cost of providing them with homebirth and birth centre options could be cost-effective.

Improving outcomes for marginalised rural families through a care navigator program.

ISSUES ADDRESSED: Health promotion programs are based on the premise that health and well-being is impacted by a person's living circumstances, not just factors within the health arena. Chronic health issues require integrated services from health and social services. Navigator positions are effective in assisting chronic disease patients to access services. This family program in a small rural town in Western New South Wales targeted marginalised families with children under five years of age with a chronic health issue. The navigator developed a cross-sectoral care plan to provide services to address family issues. The study aimed to identify navigator factors supporting improved family outcomes. METHODS: Participants included parent/clients (n = 4) and the cross-sectoral professional team (n = 9) involved in the program. During the interview, participants were asked about their perspective of the program. Interview transcripts were thematically analysed informed by the Chronic Care Model underpinned by Health Promotion Theory. RESULTS: The program improved client family's lives in relation to children's health and other family health and social issues. Trust in the care navigator was the most important factor for parents to join and engage with the program. The care navigator role was essential to maintaining client engagement and supporting cooperation between services to support families. CONCLUSION: Essential care navigator skills were commitment, ability to persuade and empower parents and other professionals. SO WHAT?: This descriptive study demonstrated the positive influence of the care navigator and the program on high risk families in a small isolated community. It can be adopted by other communities to improve life for families at risk.

Mapping the trajectories for women and their babies from births planned at home, in a birth centre or in a hospital in New South Wales, Australia, between 2000 and 2012.

BACKGROUND: In New South Wales (NSW) Australia, women at low risk of complications can choose from three birth settings: home, birth centre and hospital. Between 2000 and 2012, around 6.4% of pregnant women planned to give birth in a birth centre (6%) or at home (0.4%) and 93.6% of women planned to birth in a hospital. A proportion of the woman in the home and birth centre groups transferred to hospital. However, their pathways or trajectories are largely unknown. AIM: The aim was to map the trajectories and interventions experienced by women and their babies from births planned at home, in a birth centre or in a hospital over a 13-year period in NSW. METHODS: Using population-based linked datasets from NSW, women at low risk of complications, with singleton pregnancies, gestation 37-41 completed weeks and spontaneous onset of labour were included. We used a decision tree framework to depict the trajectories of these women and estimate the probabilities of the following: giving birth in their planned setting; being transferred; requiring interventions and neonatal admission to higher level hospital care. The trajectories were analysed by parity. RESULTS: Over a 13-year period, 23% of nulliparous and 0.8% of multiparous women planning a home birth were transferred to hospital. In the birth centre group, 34% of nulliparae and 12% of multiparas were transferred to a hospital. Normal vaginal birth rates were higher in multiparous women compared to nulliparous women in all settings. Neonatal admission to SCN/NICU was highest in the planned hospital group for nulliparous women (10.1%), 7.1% for nulliparous women planning a birth centre birth and 5.1% of nulliparous women planning a homebirth. Multiparas had lower admissions to SCN/NICU for all thee settings (hospital 6.3%, BC 3.6%, home 1.6%, respectively). CONCLUSIONS: Women who plan to give birth at home or in a birth centre have high rates of vaginal birth, even when transferred to hospital. Evidence on the trajectories of women who choose to give birth at home or in birth centres will assist the planning, costing and expansion of models of care in NSW.

Healthcare Resource Utilization and Cost Associated with Allogeneic Hematopoietic Stem Cell Transplantation: A Scoping Review.

This scoping review summarizes the evidence regarding healthcare resource utilization (HRU) and costs associated with allogeneic hematopoietic stem cell transplantation (allo-HSCT). This study was conducted in accordance with the Joanne Briggs Institute methodology for scoping reviews. The PubMed, Embase, and Health Business Elite Electronic databases were searched, in addition to grey literature. The databases were searched from inception up to November 2022. Studies that reported HRU and/or costs associated with adult (≥18 years) allo-HSCT were eligible for inclusion. Two reviewers independently screened 20% of the sample at each of the 2 stages of screening (abstract and full text). Details of the HRU and costs extracted from the study data were summarized, based on the elements and timeframes reported. HRU measures and costs were combined across studies reporting results defined in a comparable manner. Monetary values were standardized to 2022 US Dollars (USD). We identified 43 studies that reported HRU, costs, or both for allo-HSCT. Of these studies, 93.0% reported on costs, 81.4% reported on HRU, and 74.4% reported on both. HRU measures and cost calculations, including the timeframe for which they were reported, were heterogeneous across the studies. Length of hospital stay was the most frequently reported HRU measure (76.7% of studies) and ranged from a median initial hospitalization of 10 days (reduced-intensity conditioning [RIC]) to 73 days (myeloablative conditioning). The total cost of an allo-HSCT ranged from $63,096 (RIC) to $782,190 (double umbilical cord blood transplantation) at 100 days and from $69,218 (RIC) to $637,193 at 1 year (not stratified). There is heterogeneity in the reporting of HRU and costs associated with allo-HSCT in the literature, making it difficult for clinicians, policymakers, and governments to draw definitive conclusions regarding the resources required for the delivery of these services. Nevertheless, to ensure that access to healthcare meets the necessary high cost and resource demands of allo-HSCT, it is imperative for clinicians, policymakers, and government officials to be aware of both the short- and long-term health resource requirements for this patient population. Further research is needed to understand the key determinants of HRU and costs associated with allo-HSCT to better inform the design and delivery of health care for HSCT recipients and ensure the quality, safety, and efficiency of care.

Provider responses to the expansion of public subsidies in healthcare: The case of oral chemotherapy treatment in Australia.

We examine provider responses to the expansion of public subsidies in 2015 for innovative oral chemotherapy treatment, in a health system where providers were free to determine their own prices. The new treatment was known to have similar efficacy to its traditional intravenous alternative and was preferred by patients for its at-home administration. However, from a policymaker's perspective, the potential for misalignment between patient and provider preferences was significant given the shift to full reimbursement for the oral chemotherapy medication but no change in fee-for-service payments for associated chemotherapy services. Under this scenario, a shift away from traditional intravenous chemotherapy may entail reduced activity and revenues associated with infusions for providers, and we hypothesise that it may result in unintended policy consequences such as reduced take-up of the new therapy or higher prices. We implement a difference-in-difference model using national administrative data on services provided, and chemotherapy medications prescribed, by providers to 1850 patients in New South Wales, Australia. Our estimates indicate that the subsidies expanded access to oral chemotherapy for newly eligible patients by 15 percentage points. However, prices charged by providers for an episode of care rose by 23 percent, driven mostly by increases in service volumes. The results illustrate the importance of understanding differential provider responses to policy changes in financial incentives.

Higher fees and out-of-pocket costs in radiotherapy point to a need for funding reform.

Objective To elucidate the policy implications of recent trends in the funding of radiotherapy services between 2009-10 and 2021-22. Method We use national aggregate claims data to determine time trends in the fees, benefits and out-of-pocket (OOP) costs of radiotherapy and nuclear therapeutic medicine claims funded through the Medicare Benefits Schedule (MBS) program. All dollar figures are expressed in constant 2021 Australian dollars. Results Radiotherapy and nuclear therapeutic medicine MBS claims increased by 78% whereas MBS funding increased by 137% between 2009-10 and 2021-22. The main driver of Medicare funding growth has been the Extended Medicare Safety Net, which has increased by 404%. Over the 13 year observation period, the percentage of bulk-billed claims peaked in 2017-18 at 76.1% but fell to 69.8% in 2021-22. For non-bulk billed services, average OOP costs per claim increased from $20.40 in 2009-10 to $69.78 in 2021-22. Conclusion Despite increased Medicare funding, patients face increasing financial barriers to access radiation oncology services. Policies with regard to funding radiotherapy services should be reviewed to ensure that services are easily accessible and affordable for all those needing treatment and at a reasonable cost to Government.

Private provider incentives in health care: The case of caesarean births.

Private doctors and hospitals face incentives to intervene in the process of childbirth because they are employed and paid differently from their public counterparts. While private obstetric care has been associated with higher rates of caesarean birth, it is unclear to what extent this is attributable to unobserved selection effects related to clinical need or patient preferences. Using administrative birth data on over 280,000 births in Australia between 2007 and 2012, we implement an instrumental variables framework to account for the endogeneity of choice of care. We also exploit Australia's institutional framework to examine the differences in doctor-level and hospital-level incentives. We find that giving birth in a private hospital leads to a 4 percentage point increase in the probability of having an unplanned caesarean birth. Over our study period, this equates to an additional 3241 caesarean births.

Waiting times in aged care: What matters?

OBJECTIVE: To assess consumer-level socioeconomic factors associated with waiting times for access to aged care services, specifically community-based care and permanent residential care. METHODS: Administrative data on assessment outcomes and admissions to services were linked with survey data at the person-level and were used to implement a competing risks regression model. We estimated the association between health needs, and socioeconomic variables and subsequent waiting periods for individuals with approval for access. RESULTS: The main consumer-level factors driving waiting time were the individual's assessed needs, including health status, whether they lived alone and age. We found no evidence that socioeconomic status was associated with waiting times for community-based care; however, admission to residential care reflected socioeconomic factors including education levels and geographical isolation. CONCLUSION: This paper provides baseline evidence for factors affecting wait times in aged care, essential for evaluating subsequent policy reforms aimed at reducing wait times and increasing equity of access and consumer choice.

Accommodation payment plans in residential aged care: The impact of consumer choice.

OBJECTIVE: To examine changes in accommodation payments to residential aged care facilities following the introduction of consumer choice reforms in 2014. These reforms have allowed residents to choose between making lump sum refundable deposits and/or rental-style payments. METHODS: Quantitative analysis was undertaken for facility-level quarterly data of 136 separate facilities, which were operated by six providers over the period under study. RESULTS: While the total pool of payments has grown strongly, consumers have increasingly favoured rental-style payments over lump sum refundable deposits. CONCLUSION: Consumer choice has changed the landscape of accommodation payment receipts in the provision of residential aged care services. Greater understanding is needed on how consumer preferences impact on the financial risk borne by providers and their ability to invest in future capacity.

Birth models of care and intervention rates: The impact of birth centres.

Birth centres offer a midwifery-led model of care which supports a non-medicalised approach to childbirth. They are often reported as having low rates of birth intervention, however the precise impact is obscured because less disadvantaged mothers with less complex pregnancies, and who prefer and often select little intervention, are more likely to choose a birth centre. In this paper, we use a methodology that purges the impact of these selection effects and provides a causal interpretation of the impact of birth centres on intervention outcomes. Using administrative birth data on over 364,000 births in Australia's most populous state between 2001 and 2012, we implement an instrumental variables framework to address confounding factors influencing choice of birth setting. We find that giving birth in a birth centre results in significantly lower probabilities of intervention, and that critically, this impact has been increasing over time. Our estimates are larger than those in existing studies, reflecting our newer data, diverging intervention rates across birth settings, and our accounting for important selection effects. The results emphasise the greater role of birth centres in delivering on policy priorities which include greater maternal autonomy, lower intervention rates, and lower health system costs.

The cost of vaginal birth at home, in a birth centre or in a hospital setting in New South Wales: A micro-costing study.

BACKGROUND: Women want greater choice of place of birth in New South Wales, Australia. It is perceived to be more costly to health services for women with a healthy pregnancy to give birth at home or in a birth centre. It is not known how much it costs the health service to provide care for women planning to give birth in these settings. AIM: The aim of this study was to determine the direct cost of giving birth vaginally at home, in a birth centre or in a hospital for women at low risk of complications, in New South Wales. METHODS: A micro-costing design was used. Observational (time and motion) and resource use data collection was undertaken to identify the staff time and resources required to provide care in a public hospital, birth centre or at home for women with a healthy pregnancy. FINDINGS: The median cost of providing care for women who plan to give birth at home, in a birth centre and in a hospital were similar (AUD $2150.07, $2100.59 and $2097.30 respectively). Midwifery time was the largest contributor to the cost of birth at home, and overhead costs accounted for over half of the total cost of BC and hospital birth. The cost of consumables was low in all three settings. CONCLUSION: In this study, we have found there is little difference in the cost to the health service when a woman has an uncomplicated vaginal birth at home, in a birth centre or in a hospital setting.

Orthopedic inpatients' ability to accurately reproduce partial weight bearing orders.

Partial weight bearing is often prescribed for patients with orthopedic injuries. Patients' ability to accurately reproduce partial weight bearing orders is variable, and its impact on clinical outcomes is unknown. This observational study measured patients' ability to reproduce partial weight bearing orders, factors influencing this, patients' and physiotherapists' ability to gauge partial weight bearing accuracy, and the effect of partial weight bearing accuracy on long-term clinical outcomes. Fifty-one orthopedic inpatients prescribed partial weight bearing were included. All received standard medical/nursing/physiotherapy care. Physiotherapists instructed patients in partial weight bearing using the hand-under-foot, bathroom scales, and/or verbal methods of instruction. Weight bearing was measured on up to 3 occasions during hospitalization using a force-sensitive insole. Factors that had the potential to influence partial weight bearing accuracy were recorded. Patients and their physiotherapists rated their perception of partial weight bearing accuracy. Three-month clinical follow-up data were retrieved from medical records. The majority of patients (72% or more) exceeded their target load, with mean peak weight bearing as high as 19.3 kg over target load (285% of target load). Weight bearing significantly increased over the 3 measurement occasions (P<.001) and was significantly associated with greater body weight (P=.04). Patients and physiotherapists were unable to accurately gauge partial weight bearing accuracy. The incidence of clinically important complications at 3 months was 9% and not significantly associated with partial weight bearing accuracy during hospitalization (P≥.45). Patients are unable to accurately reproduce partial weight bearing orders when trained with the hand-under-foot, bathroom scales, or verbal methods of instruction.
