Partnerships for the Productive Development of the Health Economic-Industrial Complex: the health question / Parcerias para o Desenvolvimento Produtivo do Complexo Econômico-Industrial da Saúde: a questão da saúde

This paper discusses some of the main criteria used to define priorities for technological and industrial development by the Brazilian Ministry of Health regarding the Partnerships for Productive Development (PDP) Program. In order to focus on the question of how to define priorities for technological development, the methodologies developed by the WHO and the EMA for that purpose are presented. WHO's and Brazilian findings on main causes of burden of disease are briefly compared. WHO's selected findings on major therapeutical gaps and technological development priorities are also compared to priorities selected and supported by the PDP program since its inception. A divorce between medicines prioritized and supported by the PDP program and the main causes of the Brazilian burden of disease was observed. Also, the incremental cost-effectiveness ratios of several medications supported by the program were preliminarily estimated. The resulting ratios were about thirty times higher than the opportunity cost estimated for Brazil. Findings of the above comparisons and cost-effectiveness exercise indicate that inadequate choices were made by the PDP program in the way to a progressive and equanimous universal health access in Brazil, anticipating a low impact on the Brazilian total burden of disease as well as a low effectiveness, efficiency and equity of the program regarding the health of the Brazilian population as a whole.

Estudos brasileiros que analisaram as Parcerias para o Desenvolvimento Produtivo (PDP) apontam limitações do desenho e da implementação das PDPs de medicamentos vis à vis os objetivos de saúde do SUS. Este artigo discute a definição de prioridades para o desenvolvimento tecnológico e industrial do complexo da saúde (CEIS), com foco na universalidade e na equidade em saúde, tendo por objeto o programa de Parcerias para o Desenvolvimento Produtivo (PDP) do Ministério da Saúde, programa de gastos anuais multibilionários, iniciado em 2009. Para aprofundar a questão do processo utilizado para definir prioridades de desenvolvimento tecnológico, o presente trabalho revê as metodologias utilizadas pela OMSepela European Medicines Agency (EMA) para esse propósito. As prioridades de saúde definidas pela OMS, partindo principalmente do critério carga de doença, e as correspondentes lacunas terapêuticas selecionadas para desenvolvimento tecnológico, com base sobretudo em evidências de monitoramento do horizonte e de avaliação tecnológica, são resumidamente apresentadas. A seguir, foram comparados os achados do relatório da OMS_ as prioridades de saúde selecionadas e as prioridades tecnológicas resultantes_ com os achados sobre carga de doença no Brasil e as prioridades selecionadas e apoiadas pelas PDPs. Observou-se um divórcio entre as prioridades medicamentosas apoiadas pelas PDPs e as principais causas de carga de doença no país. Abordamos ainda, nesse artigo, o papel da análise de custo-efetividade e do custo de oportunidade na discussão das escolhas do programa PDP. O exemplo trabalhado indica que o custo de oportunidade de várias tecnologias apoiadas pelas PDPs vigentes é dezenas de vezes superior ao limiar de custo-efetividade estimado para o Brasil. O divórcio entre as prioridades apoiadas pelas PDPs e as principais causas de carga de doença no país e o limiar de custo-efetividade assumido pelo programa PDP indicam escolhas insatisfatórias na busca para alcançar, de forma progressiva e equânime, o acesso universal à atenção de saúde em nosso país, no SUS. Essas escolhas devem resultar em uma baixa efetividade, baixa eficiência e baixa equidade do programa do ponto de vista da saúde da população brasileira como um todo.

Aligning opportunity cost and net benefit criteria: the health shadow price.

Given constrained healthcare budgets and many competing demands, public health decision-making requires comparing the expected cost and health outcomes of alternative strategies and associated adoption and financing actions. Opportunity cost (comparing outcomes from the best alternative use of budgets or actions in decision making) and more recently net benefit criteria (relative valuing of effects at a threshold value less costs) have been key concepts and metrics applied toward making such decisions. In an ideal world, opportunity cost and net benefit criteria should be mutually supportive and consistent. However, that requires a threshold value to align net benefit with opportunity cost assessment. This perspective piece shows that using the health shadow price as the ICER threshold aligns net benefit and opportunity cost criteria for joint adoption and financing actions that arise when reimbursing any new strategy or technology under a constrained budget. For an investment strategy with ICER at the health shadow price Bc = 1/(1/n + 1/d-1/m), net benefit of reimbursing (adopting and financing) that strategy given an incremental cost-effectiveness ration (ICER) of actual displacement, d, in financing, is shown to be equivalent to that of the best alternative actions, the most cost-effective expansion of existing programs (ICER = n) funded by the contraction of the least cost-effective programs (ICER = m). Net benefit is correspondingly positive or negative if it is below or above this threshold. Implications are discussed for creating pathways to optimal public health decision-making with appropriate incentives for efficient displacement as well as for adoption actions and related research.

Design and validation of a decision support checklist for efficient resource allocation in research projects during proposal preparation.

PURPOSE: This article presents the design and validation of evaluation criteria checklist aimed at facilitating decision-making processes regarding participation in research projects and allocation of resources before the preparation of research proposals. MATERIALS AND METHODS: A multidisciplinary team developed a comprehensive evaluation focusing on the proposal preparation phase of research projects. A Delphi survey method was used to establish a connection between the relevance of the project and the possible success of research proposals. Assessment criteria were agreed upon, each assigned specific weights. The results of the survey were applied to a database of 62 proposals for which our research group sought funding during 2020-2021. The method was validated using the funding body's outcomes (approval or rejection) of the submitted proposals as the ground truth per project type (national, European and regional). RESULTS: The results of the survey generated a checklist of 8 criteria (excellence, impact, and efficiency aspects) that effectively assess the possibility of success of research proposals during the preparatory phase. For national projects, the tool validation demonstrated a sensitivity of 100% and a specificity of 76.19%; European projects exhibited a sensitivity of 100% and a specificity of 53.84%; and regional projects showed a sensitivity of 80% and a specificity of 30%. CONCLUSIONS: By establishing an agreed set of evaluation criteria, the developed comprehensive index enables a more precise decision support tool for the participation in research proposals and the allocation of necessary resources. This control system saves valuable time and effort for research groups while enhancing the overall efficiency of available resources.

To what extent did implementing a community-embedded intervention align with the goals and roles of stakeholders in adolescent sexual and reproductive health?

BACKGROUND: Adolescents' sexual and reproductive health (SRH) needs are largely unmet due to poor access to SRH information and services. A multicomponent community-embedded intervention, comprising advocacy to policymakers and community leaders, training of health workers on the provision of youth-friendly SRH services, and establishment of school health clubs, was implemented in Ebonyi State, Nigeria, to improve access to SRH information and services for adolescents aged 13-18 years in selected communities and secondary schools. This study explored the extent to which the intervention aligned with goals and roles of stakeholders in the State. METHODS: Qualitative in-depth interviews (30) were conducted with key stakeholders in adolescent health programming in the State, and community gatekeepers (traditional and religious leaders) in the intervention communities. Sex-disaggregated focus group discussions (10) were conducted with health service providers, parents/guardians of adolescents. Data was analyzed deductively based on fit of strategy and two constructs of the Theoretical Framework for Acceptability - burden, and opportunity cost. The transcripts were coded in NVivo 12, and the subthemes that emerged from each construct were identified. RESULTS: Stakeholders perceived the ASRH intervention activities to align with their individual goals of sense of purpose from serving the community and organizational goals of improving the visibility of adolescent reproductive health programs and aligned with their routine work. Hence, implementing or participating in the interventions was not considered a burden by many. Although the delivery of the interventions constituted additional workload and time commitment for the implementers, the benefits of partaking in the intervention were perceived to outweigh the inputs that they were required to make. Some of the community health workers in the intervention felt that provision of financial incentive will help with making the intervention less burdensome. To participate in the intervention, opportunity cost included forgoing work and business activities as well as family commitments. CONCLUSION: Findings from the study show that the intervention aligned with individual/organizational goals of stakeholders. To improve acceptability of the ASRH interventions, interventions should leverage on existing programs and routine work of people who will deliver the interventions.

Adolescence is a period of transition and marked physical and mental changes with an increased need for sexual and reproductive health services. However, these needs are not usually met as adolescent face challenges in receiving care such as negative attitudes of health workers, fear of consequences of disclosing sexual and reproductive care received to parents amongst other things. An intervention aimed at improving their access to sexual and reproductive health services was implemented in Ebonyi State, Nigeria. This study assessed the alignment of the intervention to the individual and organizational goals of the stakeholders, the burden involved in participating in the intervention as well as the things needed to be forgone. Findings show that the intervention aligned with the stakeholder routine work, organizational work plans and individual goals. Participating in the intervention was not considered bothersome by many stakeholders because the impact their work make in the community makes them feel fulfilled. Participating in the intervention increases workload of the stakeholders. Stakeholders had to forgo work and business engagements to participate and some felt incentives can help to keep them motivated and interested in the project. To improve acceptability of adolescent sexual and reproductive health interventions, interventions should be tailored to the routine work of the implementers of the strategy and plans for incentives be made for stakeholders who deliver interventions.

What Is Mental Effort: A Clinical Perspective.

Although mental effort is a frequently used term, it is poorly defined and understood. Consequently, its usage is frequently loose and potentially misleading. In neuroscience research, the term is used to mean both the cognitive work that is done to meet task demands and the subjective experience of performing that work. We argue that conflating these two meanings hampers progress in understanding cognitive impairments in neuropsychiatric conditions because cognitive work and the subjective experience of it have distinct underlying mechanisms. We suggest that the most coherent and clinically useful perspective on mental effort is that it is a subjective experience. This makes a clear distinction between cognitive impairments that arise from changes in the cognitive apparatus, as in dementia and brain injury, and those that arise from subjective difficulties in carrying out the cognitive work, as in attention-deficit/hyperactivity disorder, depression, and other motivational disorders. We review recent advances in neuroscience research that suggests that the experience of effort has emerged to control task switches so as to minimize costs relative to benefits. We consider how these advances can contribute to our understanding of the experience of increased effort perception in clinical populations. This more specific framing of mental effort will offer a deeper understanding of the mechanisms of cognitive impairments in differing clinical groups and will ultimately facilitate better therapeutic interventions.

Social Decision-Making Analysis: A General Approach to Inform Decisions on Resources in the Public Sector.

OBJECTIVES: Public expenditure aims to achieve social objectives by improving a range of socially valuable attributes of benefit (arguments in a social welfare function). Public expenditure is typically allocated to public sector budgets, where budget holders are tasked with meeting a subset of social objectives. METHODS: Decision makers require an evidence-based assessment of whether a proposed investment is likely to be worthwhile given existing levels of public expenditure. However, others also require some assessment of whether the overall level and allocation of public expenditure are appropriate. This article proposes a more general theoretical framework for economic evaluation that addresses both these questions. RESULTS: Using a stylized example of the economic evaluation of a new intervention in a simplified UK context, we show that this more general framework can support decisions beyond the approval or rejection of single projects. It shows that broader considerations about the level and allocation of public expenditure are possible and necessary when evaluating specific investments, which requires evidence of the range of benefits offered by marginal changes in different types of public expenditure and normative choices of how the attributes of benefit gained and forgone are valued. CONCLUSIONS: The proposed framework shows how to assess the value of a proposed investment and whether and how the overall level of public expenditure and its allocation across public sector budgets might be changed. It highlights that cost-benefit analysis and cost-effectiveness analysis can be viewed as special cases of this framework, identifying the weakness with each.

The Economic Costs of Informal Care: Estimates from a National Cross-Sectional Survey in The Netherlands.

Faced with an unprecedented demand for long-term care, European health care systems are moving towards mixed care models, where the welfare state and informal caregivers share care responsibilities. While informal care is often viewed as a means of alleviating pressure on public care, it comes with significant economic costs for caregivers, their employers, and society at large. This study uses nationally representative data to estimate the total direct (informal care time and out-of-pocket costs) and indirect (productivity) economic costs of informal care in the Netherlands in 2019. Informal care time costs are estimated using the opportunity cost and the proxy good methods. Indirect costs are estimated using the human capital and friction cost approaches. Our results reveal the considerable annual societal cost of informal care in the Netherlands, ranging between €17.5 billion and €30.1 billion, depending on the valuation approach. These costs are equivalent to 2.15% and 3.71% of Dutch GDP in 2019, comparable to the public expenditure on long-term care in that year. Female caregivers account for slightly more than half (53%-57%) of the total costs. Around 57%-88% of these costs are in the form of informal care time. The main driver of indirect costs is the temporary cessation of work, which comprises 12%-17% of the total costs. Findings corroborate that substantial resources, yet thus far largely disregarded, are spent on informal care even in a country with a relatively generous public long-term care system.

Systematic review of the impact of health care expenditure on health outcome measures: implications for cost-effectiveness thresholds.

OBJECTIVE: Empirical estimates of the impact of healthcare expenditure on health outcome measures may inform the cost-effectiveness threshold (CET) for guiding funding decisions. This study aims to systematically review studies that estimated this, summarize and compare the estimates by country income level. METHODS: We searched PubMed, Scopus, York Research database, and [anonymized] for Reviews and Dissemination database from inception to 1 August 2023. For inclusion, a study had to be an original article, estimating the impact of healthcare expenditure on health outcome measures at a country level, and presented estimates, in terms of cost per quality-adjusted life year (QALY) or disability-adjusted life year (DALY). RESULTS: We included 18 studies with 385 estimates. The median (range) estimates were PPP$ 11,224 (PPP$ 223 - PPP$ 288,816) per QALY gained and PPP$ 5,963 (PPP$ 71 - PPP$ 165,629) per DALY averted. As ratios of Gross Domestic Product per capita (GDPPC), these estimates were 0.376 (0.041-182.840) and 0.318 (0.004-37.315) times of GDPPC, respectively. CONCLUSIONS: The commonly used CET of GDPPC seems to be too high for all countries, but especially low-to-middle-income countries where the potential health losses from misallocation of the same money are greater. REGISTRATION: The review protocol was published and registered in PROSPERO (CRD42020147276).

Resource allocation in public sector programmes: does the value of a life differ between governmental departments?

BACKGROUND: The value of a life is regularly monetised by government departments for informing resource allocation. Guidance documents indicate how economic evaluation should be conducted, often specifying precise values for different impacts. However, we find different values of life and health are used in analyses by departments within the same government despite commonality in desired outcomes. This creates potential inconsistencies in considering trade-offs within a broader public sector spending budget. We provide evidence to better inform the political process and to raise important issues in assessing the value of public expenditure across different sectors. METHODS: Our document analysis identifies thresholds, explicitly or implicitly, as observed in government-related publications in the following public sectors: health, social care, transport, and environment. We include both demand-side and supply-side thresholds, understood as societies' and governments' willingness to pay for health gains. We look at key countries that introduced formal economic evaluation processes early on and have impacted other countries' policy development: Australia, Canada, Japan, New Zealand, the Netherlands, and the United Kingdom. We also present a framework to consider how governments allocate resources across different public services. RESULTS: Our analysis supports that identifying and describing the Value of a Life from disparate public sector activities in a manner that facilitates comparison is theoretically meaningful. The optimal allocation of resources across sectors depends on the relative position of benefits across different attributes, weighted by the social value that society puts on them. The value of a Quality-Adjusted Life Year is generally used as a demand-side threshold by Departments of transport and environment. It exceeds those used in health, often by a large enough proportion to be a multiple thereof. Decisions made across departments are generally based on an unspecified rationing rule. CONCLUSIONS: Comparing government expenditure across different public sector departments, in terms of the value of each department outcome, is not only possible but also desirable. It is essential for an optimal resource allocation to identify the relevant social attributes and to quantify the value of these attributes for each department.

Opportunity Cost of Vitreoretinal Surgeries.

Purpose: To compare physician reimbursements for vitreoretinal surgeries with office-based patient care. Methods: A theoretical model was performed comparing physician work reimbursements for the 10 most common vitreoretinal surgeries with office-based work relative value units (wRVUs) that could have been generated during the same global time period. The reference physician was modeled at 40 patients per 8-hour workday. A lower volume physician and higher volume physician were modeled at 30 patients/day and 50 patients/day, respectively. The reimbursement rates and allocated times for surgery were based on the 2021 values set by Medicare, and the average wRVU per office visit was based on 2021 real-world data from the Vestrum Retinal Healthcare Database. Results: In the reference case, performing any of the 10 most common vitreoretinal surgeries was associated with an opportunity cost with a weighted mean of 49% (range, 40%-68%) relative to lost office productivity. The Centers for Medicare & Medicaid Services (CMS) allocated a weighted mean intraservice time of 73 minutes; however, the reference physician would have to complete the surgery with a weighted average of 5 minutes (range, -31-12 minutes) for surgical wRVUs to equal office-based reimbursements. Performing these 10 surgeries was associated with a 25% opportunity cost even for the lower volume physician and 61% for the higher volume physician. Probability sensitivity analysis with a range of conditions identified opportunity costs from surgery in over 99% of simulated scenarios. Conclusions: Medicare reimbursements for the physician work component of vitreoretinal surgeries represented a significant opportunity cost for the physician relative to office-based patient care of equivalent time, especially for busier physicians. The model did not explore practice overhead and professional liability insurance, which are factored separately by CMS and may influence the opportunity cost depending on utilization. The average threshold surgery times for surgical reimbursements to equal office-based reimbursements may be difficult to achieve.

The Economic Value of Caregiving in Chile.

Population aging will increase the demand for long-term care services. Many countries, including Chile, have not implemented comprehensive responses to address these demands, relying on informal care. This article aims to estimate the economic value of caregiving in Chile, contributing to filling a gap in the literature and the policy debate. Economic value is estimated using replacement and opportunity cost approaches using two nationally representative databases: one survey on time use (to estimate hours of caregiving) and one on socioeconomic characterization (to identify caregivers and wages). Regressions for the determinants of caregiving effort and wages in the formal labor market are used to calculate the market value of caregiving time. Results show that the yearly value of caregiving ranges between US$266 million (when assuming a wage equal to the minimum wage for all caregivers) and US$4,946 million (when replacing all caregivers with nurses), i.e. between 0.11% and 1.95% of the country's gross domestic product. The analysis provides several estimations of the economic value of caregivers in Chile and, even considering these calculations can be underestimated, the results show the need to highlight and value the contribution of caregivers and implement policies to address the increase in long-term care needs in the country.

Educational Mismatch and Workers' Fertility Intentions: Evidence from China.

This paper focuses on the impact of the educational mismatch on workers' fertility intentions and explores the underlying mechanisms. Empirical research based on the China Family Panel Survey (CFPS) data shows that undereducation has a negative effect on the fertility intentions of women aged 18-35, whereas overeducation reports no effect, a finding that remains stable in the robustness test and the IV model. An explanation for this phenomenon is that undereducated female workers have a wage premium and higher expectations of career development, which implies a greater opportunity cost of fertility. The heterogeneity analysis shows that women with low socio-economic status, especially those who are less educated, from low-income households, and who are employed in the private sector, are more affected. It is therefore necessary to reduce the substitution risk in the labor market for this group and to lighten the fertility burden and pressure on women.

Regulatory Focus and Financial Satisfaction: The Sequential Mediating Roles of Construal Level and Opportunity Cost Consideration Among College Students.

Background: Recently, the importance of individual differences has been recognized in the literature of general life satisfaction and domain-specific satisfaction, however, empirical research exploring the relationship between individual differences in self-regulatory focus and financial satisfaction remains relatively sparse, and less is known about the underlying processes that may mediate this relationship. The current study addressed these gaps by investigating whether and how self-regulatory focus (promotion vs prevention) as a motivational trait is related to college students' financial satisfaction. A model was tested in which this association was sequentially mediated by the effects of construal level and opportunity cost consideration. Methods: A total of 552 college students (38.6% male; ages 19-25) completed a packet of questionnaires that measured trait regulatory focus, construal level, opportunity cost consideration, and financial satisfaction. Results: The mediation model was tested via multiple regression analyses and bootstrapping procedure. The results supported a sequential mediation model, suggesting that predominantly promotion-focused regulation is associated with information construal at a more abstract level, increasing the consideration of opportunity costs, and subsequently enhancing financial satisfaction. Discussion: These findings can broaden our understanding of how trait regulatory focus potentially influences financial satisfaction, offering new directions towards improving college students' financial satisfaction.

Opportunity cost determines free-operant action initiation latency and predicts apathy.

BACKGROUND: Apathy, a disabling and poorly understood neuropsychiatric symptom, is characterised by impaired self-initiated behaviour. It has been hypothesised that the opportunity cost of time (OCT) may be a key computational variable linking self-initiated behaviour with motivational status. OCT represents the amount of reward which is foregone per second if no action is taken. Using a novel behavioural task and computational modelling, we investigated the relationship between OCT, self-initiation and apathy. We predicted that higher OCT would engender shorter action latencies, and that individuals with greater sensitivity to OCT would have higher behavioural apathy. METHODS: We modulated the OCT in a novel task called the 'Fisherman Game', Participants freely chose when to self-initiate actions to either collect rewards, or on occasion, to complete non-rewarding actions. We measured the relationship between action latencies, OCT and apathy for each participant across two independent non-clinical studies, one under laboratory conditions (n = 21) and one online (n = 90). 'Average-reward' reinforcement learning was used to model our data. We replicated our findings across both studies. RESULTS: We show that the latency of self-initiation is driven by changes in the OCT. Furthermore, we demonstrate, for the first time, that participants with higher apathy showed greater sensitivity to changes in OCT in younger adults. Our model shows that apathetic individuals experienced greatest change in subjective OCT during our task as a consequence of being more sensitive to rewards. CONCLUSIONS: Our results suggest that OCT is an important variable for determining free-operant action initiation and understanding apathy.

Farmer satisfaction and short food supply chains.

In response to a commentary on our research article (Azima and Mundler in Agric Hum Values 39:791-807, 2022), we address the argument that increased reliance on family farm labor with low or no opportunity costs leads to higher net revenue and greater economic satisfaction. Our response provides a nuanced perspective on this issue in the context of short food supply chains. We also examine the share of total farm sales from short food supply chains in terms of its effect size on farmer job satisfaction. Finally, we emphasize the need for further research into the sources of occupational satisfaction among farmers involved in such marketing channels.

Vaccine-Preventable Hospitalisations from Seasonal Respiratory Diseases: What Is Their True Value?

Hospitals in England experience extremely high levels of bed occupancy in the winter. In these circumstances, vaccine-preventable hospitalisations due to seasonal respiratory infections have a high cost because of the missed opportunity to treat other patients on the waiting list. This paper estimates the number of hospitalisations that current vaccines against influenza, pneumococcal disease (PD), COVID-19, and a hypothetical Respiratory Syncytial Virus (RSV) vaccine, could prevent in the winter among older adults in England. Their costs were quantified using a conventional reference costing method and a novel opportunity costing approach considering the net monetary benefit (NMB) obtained from alternative uses of the hospital beds freed-up by vaccines. The influenza, PD and RSV vaccines could collectively prevent 72,813 bed days and save over £45 million in hospitalisation costs. The COVID-19 vaccine could prevent over 2 million bed days and save £1.3 billion. However, the value of hospital beds freed up by vaccination is likely to be 1.1-2 times larger (£48-93 million for flu, PD and RSV; £1.4-2.8 billion for COVID-19) when quantified in opportunity cost terms. Considering opportunity costs is key to ensuring maximum value is obtained from preventative budgets, as reference costing may significantly underestimate the true value of vaccines.

Opportunity Cost to Attending Surgeons of Intraoperative Training for Residents in Cataract Surgery.

Purpose: To estimate the opportunity cost to attending surgeons of teaching residents cataract surgery in the operating room. Patients and methods: Operating room records at an academic teaching hospital from July 2016 to July 2020 were analyzed in this retrospective review of cases. Cases were identified using Current Procedural Terminology (CPT) codes 66982 and 66984 for cataract surgery. Outcomes measured include operative time and work relative value units (wRVUs). Cost analysis was performed using the generic 2021 Medicare Conversion Factor. Results: Of 8813 cases, 2906 (33.0%) included resident involvement. For CPT 66982 cases, median (interquartile range (IQR)) operative time was 47 (22) minutes with resident involvement and 28 (18) minutes without (p<0.001). For CPT 66984 cases, median (IQR) operative time was 34 (15) minutes with resident involvement and 20 (11) minutes without (p<0.001). Median wRVUs was 78.5 (20.9) with resident involvement and 61.0 (14.4) without (p<0.001) which converted to an opportunity cost (IQR) per case of $1393.72 ($1055.63). Among cases involving residents, median operative time was significantly higher during the first and second quarters (p<0.001) and for every quarter when compared to cases performed by attendings only (p<0.001). Conclusion: Teaching cataract surgery in the operating room is associated with a considerable opportunity cost for attending surgeons.

Quantifying the Opportunity Cost of Resident Involvement in Academic Orthopedic Shoulder Arthroplasty: A Matched - Pair Analysis.

Background: There is minimal work defining the economic impact of resident participation in shoulder arthroplasty. Thus, this study quantified the opportunity cost of resident participation in total shoulder arthroplasty (TSA) and hemiarthroplasty (HA) by determining differences in operative time, relative value units (RVUs)/hour, and RVUs/case. Methods: A retrospective analysis of shoulder arthroplasty procedures were identified from the ACS-NSQIP database from 2006 to 2014 using CPT codes. Demographic, comorbidity, preoperative laboratory data and surgical procedure were used to develop matched cohorts. Mean differences in operative time, RVUs/case and RVUs/hour between attending-only (AO) cases and cases with resident involvement (RI) were examined. Cost analysis was performed to identify differences in RVUs generated per hour in dollars/case. Results: A total of 1786 AO and 1102 RI cases were identified. With the exception of PGY-3 and PGY-4 cases, RI cases had lower mean operative times compared to AO cases. The cost of RI was highest for PGY-3 ($199.87 per case) and PGY-4 ($9 .2 9) residents with all other postgraduate years providing a cost reduction. Discussion: Involvement of residents was associated with shorter operative times leading to a savings of $29.64 per case. Involvement of intermediate-level (PGY-3) residents were associated with increased costs that ultimately decreased as residents became more senior.

Comparative analyses of holder pasteurization vs. HTST pasteurization for donor milk: a cost-minimization study applicable to human milk banks.

BACKGROUND: High-temperature short-time (HTST) pasteurization (72-75 °C, 15 s) is an alternative treatment to traditional Holder pasteurization (HoP) (62ºC, 30 min) for donor milk. HTST pasteurization guarantees the milk's microbiological safety and retains more of its biologically and nutritionally active compounds, but the cost of implementing this technology for a human milk bank is unknown. METHODS: A cost-minimization study was carried out on the facilities of a regional human milk bank in a public hospital. Total production costs (fixed plus variables) were quantified using HTST pasteurization and HoP in three hypothetical scenarios: (1) costs of the first 10 L of pasteurized milk in a newly opened milk bank; (2) costs of the first 10 L of pasteurized milk in an active milk bank; and (3) costs using the maximum production capacity of both technologies in the first two years of operation. The following costs were analyzed: health care professionals, equipment and software, external services, and consumables. RESULTS: In scenario 1, the total production costs were € 228,097.00 for the HTST method versus € 154,064.00 for the HoP method. In scenario 2, these costs were similar (€ 6,594.00 for HTST pasteurization versus € 5,912.00 for HoP). The cost of healthcare professionals was reduced by more than half when pasteurization was carried out by the HTST method versus the Holder method (€ 84.00 and € 191.00, respectively). In scenario 3, the unit cost of milk pasteurized by the HTST method decreased from the first to the second year by 43.5%, while for the HoP method, it decreased by 30%. CONCLUSIONS: HTST pasteurization requires a high initial investment in equipment; however, it provides a significant minimization of production costs in the long term, pasteurizes large quantities of donor milk per working day and achieves a more efficient management of the time of the health care professionals in charge of the bank's operation compared to HoP.
