Este estudo buscou analisar a percepção dos docentes e pesquisadores brasileiros quanto aos métodos baseados em atividades. Para tanto, foi realizada uma survey com 34 docentes e pesquisadores especialistas em custos dos programas de pós-graduação em Ciências Contábeis no Brasil. Na análise dos resultados foi utilizada a estatística descritiva e empregado o teste de aderência (χ²). A consistência interna do instrumento de pesquisa foi calculada por meio do Alpha de Cronbach o que conferiu consistência ao mesmo. Os resultados demonstram que sob a percepção dos docentes e pesquisadores o Activity Based Cost (ABC) foi capaz de reduzir a subjetividade e arbitrariedade do método por absorção, bem como melhorar as informações para a tomada de decisão. No entanto, o Time-Driven Activity-Based Costing (TDABC) não é considerado de forma unânime uma evolução do método ABC, uma vez que não há uma opinião uníssona se o método foi capaz de reduzir a complexidade e diminuir a necessidade de tempo e recursos relacionados à sua implementação e manutenção. Quanto ao ABM, ele pode ser considerado um sistema de gestão, do qual o ABC constitui sua extensão instrumental.Palavras-chave: Activity-Based Costing. Time Driven Activity-Based Costing.

AbstractObjectivesThe aim of this study was: (1) to adapt the time‐driven activity‐based costing (TDABC) method to emergency department (ED) ambulatory care; (2) to estimate the cost of care associated with frequently encountered ambulatory conditions; and (3) to compare costs calculated using estimated time and objectively measured time. MethodsTDABC was applied to a retrospective cohort of patients with upper respiratory tract infections, urinary tract infections, unspecified abdominal pain, lower back pain and limb lacerations who visited an ED in Québec City (Canada) during fiscal year 2015–2016. The calculated cost of care was the product of the time required to complete each care procedure and the cost per minute of each human resource or equipment involved. Costing based on durations estimated by care professionals were compared to those based on objective measurements in the field. ResultsOverall, 220 care episodes were included and 3080 time measurements of 75 different processes were collected. Differences between costs calculated using estimated and measured times were statistically significant for all conditions except lower back pain and ranged from $4.30 to $55.20 (US) per episode. Differences were larger for conditions requiring more advanced procedures, such as imaging or the attention of ED professionals. ConclusionsThe greater the use of advanced procedures or the involvement of ED professionals in the care, the greater is the discrepancy between estimated‐time‐based and measured‐time‐based costing. TDABC should be applied using objective measurement of the time per procedure.

Purpose: The understanding of logistics process in terms of costs and profitability is a complex task and there is a need of more research and applied work on these issues. In this research project, the concepts underlying Time-Driven Activity Based Costing (TDABC) have been used in the context of logistics costs. Design/methodology/approach: A Distribution Centre of wood and carpentry related materials has been studied. A multidisciplinary team has been composed to support the project including the researchers and three employees of the company responsible for accounting, logistics and warehousing. The design and implementation of the costing model asked for a deep understanding of the different tasks and processes that should be considered. Accordingly, a TDABC model for the logistics function was developed. Findings: The cost model presented here is supported on a series of time equations designed for the logistics function which allow the analysis and discussion of costs and profitability of different cost objects namely, products, clients, distribution channels, processes and activities. The cost of unused capacity and the effectiveness of logistics processes are also highlighted in this model. Research limitations/implications: In a case study, results and implications cannot be directly or immediately generalized. Nevertheless, the proposed time equations and cost model can be easily adapted to explain other types of logistics functions and it gives the foundations or other TDABC models with more than one capacity cost rate. Practical implications: The TDABC model developed in this case study can be used in similar cases and as a basis for the analysis of logistics costs in other logistics processes. Furthermore, managers can rely on the proposed approach to analyze products' profitability and logistics cost structure. Originality/value: In this case, different capacity cost rates were computed in order to reflect appropriately the logistics function which was presented in two different processes: internal logistics and distribution. These processes have specific resources allocated and should be measured differently. This is in line with Kaplan and Anderson (2004, 2007) who have suggested a more complex TDABC model with more than one capacity cost rate for these situations.

Background Implementation strategies increase the adoption of evidence-based practices, but they require resources. Although information about implementation costs is critical for decision-makers with budget constraints, cost information is not typically reported in the literature. This is at least partly due to a need for clearly defined, standardized costing methods that can be integrated into implementation effectiveness evaluation efforts. Methods We present a pragmatic approach to systematically estimating detailed, specific resource use and costs of implementation strategies that combine time-driven activity-based costing (TDABC), a business accounting method based on process mapping and known for its practicality, with a leading implementation science framework developed by Proctor and colleagues, which guides specification and reporting of implementation strategies. We illustrate the application of this method using a case study with synthetic data. Results This step-by-step method produces a clear map of the implementation process by specifying the names, actions, actors, and temporality of each implementation strategy; determining the frequency and duration of each action associated with individual strategies; and assigning a dollar value to the resources that each action consumes. The method provides transparent and granular cost estimation, allowing a cost comparison of different implementation strategies. The resulting data allow researchers and stakeholders to understand how specific components of an implementation strategy influence its overall cost. Conclusion TDABC can serve as a pragmatic method for estimating resource use and costs associated with distinct implementation strategies and their individual components. Our use of the Proctor framework for the process mapping stage of the TDABC provides a way to incorporate cost estimation into implementation evaluation and may reduce the burden associated with economic evaluations in implementation science.

Background Time-driven activity-based costing (TDABC) and activity-based costing (ABC) are methods used in the healthcare sector to assess the costs of patient care pathways. These methods help identify opportunities for optimizing and reducing activity times without compromising the quality of care. TDABC is recommended in the Value-Based Healthcare (VBHC) model to assess the outcomes of care pathways in relation to their associated costs. By focusing on the creation of value for patients, TDABC helps identify the interventions and processes that provide the most value in terms of clinical outcomes and patient satisfaction. This enables healthcare organizations to make informed decisions on improvements that will maximize value for patients. The aim of the study is to evaluate the cost of the oncology thoracic surgery care pathway prior to and following the implementation of digital health solution. Methods We have chosen to use the TDABC and ABC methods to calculate the costs of care pathway for oncology patients undergoing thoracic surgery in two healthcare establishments prior to and following the implementation of a digital health solution. By using these methods, we were able to calculate the costs associated with each stage of the patients’ care pathway. This has given us a clearer picture of the costs associated with each activity and a better understanding of the sources of expenditure. Results The results show that implementing the digital health solution and applying the principles of the VBHC model have provided tangible benefits in terms of reviewing processes and the roles of the various players involved, eliminating unnecessary or non-value-added activities, automating administrative or repetitive tasks, and improving coordination between the two healthcare establishments and between healthcare professionals. These improvements have contributed to better patient care. Conclusions Given the success observed in this pilot project, decision-makers chose to persistently implement this digital health solution for specific care pathways over the long term. Additionally, there is a commitment to further enhance the platform to align closely with the needs and the expectations of healthcare professionals. This proactive approach aims to ensure optimal utilization of resources, ultimately providing the best care to patients.

Micro-costing studies still deserving for methods orientation that contribute to achieve a patient-specific resource use level of analysis. Time-driven activity-based costing (TDABC) is often employed by health organizations in micro-costing studies with that objective. However, the literature shows many deviations in the implementation of TDABC, which might compromise the accuracy of the results obtained. One reason for that can be attributed to the non-existence of a step-by-step orientation to conduct cost analytics with the TDABC specific for micro-costing studies in healthcare. This article aimed at exploring the literature and practical cases to propose an eight-step framework to apply TDABC in micro-costing studies for health care organizations. The 8-step TDABC framework is presented and detailed exploring online spreadsheets already coded to demonstrate data structure and math formula building. A list of analyses that can be performed is suggested, including an explanation about the information that each analysis can provide to increase the organization capability to orient decision making. The case study developed show that actual micro-costing of health care processes can be achieved with the 8-step TDABC framework and its use in future researches can contribute to increase the number of studies that achieve high-quality level in cost information, and consequently, in health resource evaluation.

Background The advent of novel robotic platforms requires that managers base their decisions on the value these platforms generate. This study showcases how micro-costing methodologies can assist managers in the decision-making process regarding the implementation of new robotic platforms within the value-based healthcare (VBHC) framework. Methods We applied time-driven activity-based costing (TDABC) to evaluate cost disparities between the da Vinci and Hugo robotic systems for robot-assisted radical prostatectomy (RARP). Data were collected from consecutively enrolled patients with organ-confined prostate cancer. Basic cost information was gathered from Azienda Universitaria Integrata di Verona’s finance and pharmacy departments. We conducted cost and sensitivity analyses to evaluate the most cost-sensitive parameters. Results The da Vinci system incurred higher total costs for RARP than the Hugo system (€4,97.21 vs. € 3,511.73, p -value < 0.001) However, excluding surgical kit costs, the da Vinci platform proved less expensive (€1,481.18 vs. €1,926.18, p -value < 0.001). Sensitivity analyses identified surgical kit costs as the most influential parameter, followed by surgical duration and platform costs. Conclusions This study highlights the importance of micro-costing practices in supporting managerial decisions within a VBHC framework. When clinical outcomes are equivalent, the value of robotic platforms is related to cost savings. By using TDABC and sensitivity analyses, managers can pinpoint critical activities and parameters to optimize the effective adoption of new platforms.

This study evaluated the influence of technology on accurately measuring costs using time-driven activity-based costing (TDABC) in healthcare provider organizations by identifying the most recent scientific evidence of how it contributed to increasing the value of surgical care. This is a literature-based analysis that mainly used two data sources: first, the most recent systematic reviews that specifically evaluated TDABC studies in the surgical field and, second, all articles that mentioned the use of CareMeasurement (CM) software to implement TDABC, which started to be published after the publication of the systematic review. The articles from the systematic review were grouped as manually performed TDABC, while those using CM were grouped as technology-based studies of TDABC implementations. The analyses focused on evaluating the impact of using technology to apply TDABC. A general description was followed by three levels of information extraction: the number of cases included, the number of articles published per year, and the contributions of TDABC to achieve cost savings and other improvements. Fourteen studies using real-world patient-level data to evaluate costs comprised the manual group of studies. Thirteen studies that reported the use of CM comprised the technology-based group of articles. In the manual studies, the average number of cases included per study was 160, while in the technology-based studies, the average number of cases included was 4,767. Technology-based studies, on average, have a more comprehensive impact than manual ones in providing accurate cost information from larger samples. TDABC studies supported by technologies such as CM register more cases, identify cost-saving opportunities, and are frequently used to support reimbursement strategies based on value. The findings suggest that using TDABC with the support of technology can increase healthcare value.

Background Psoriasis a chronic inflammatory skin disease, poses a substantial economic burden on healthcare systems globally. This study examines psoriasis consultations from the provider’s perspective within a dermatology department, aiming to generate detailed cost data to support value-based care. Specifically, it investigates the drivers of consultation-level cost variability, explores opportunities for efficiency, and also estimates one-year treatment costs to inform the development of bundled payment models. The goal is to highlight the importance of patient cost transparency and improving cost structures in chronic disease settings. Methods Using Time-Driven Activity-Based Costing (TD-ABC), treatment costs associated with nurses, doctors, and total visits for 127 patients with mild and moderate forms of psoriasis were measured. Financial data was collected in collaboration with the hospital’s financial department. During consultations, nurses and physicians recorded time and patient-related information. Additional or missing details were retrieved from patient medical files. Descriptive analyses assessed mean costs and variability by patient and disease characteristics. Independent variables: therapy type, patient status (new vs. returning), comorbidities, and treatment changes, were stratified to compare cost differences across groups. Results Mean consultation costs were €55, with a minimum and maximum of €25 and €110. New patients incurred 40% higher costs than returning ones, mainly due to longer interactions with nurses and physicians. Key cost drivers for a total consultation included patient status, personality traits, nurse experience, and therapy switches. Physician consultations were particularly impacted by treatment changes and patient engagement levels. Annual treatment costs varied substantially by medication type: topical treatments averaged €325 per year, systemic treatments €1,353, and biological therapies €11,920, highlighting the significant impact of medication choice on overall expenses. Conclusions This study highlighted substantial variability in consultation and yearly treatment costs for psoriasis patients. These findings emphasized the critical need for detailed cost data to optimise departmental workflows, support efficient resource allocation, and inform the design of equitable bundled payment models. Improving cost transparency was shown to strengthen clinical and financial decision-making. Future research was recommended to explore the cost implications of comorbidities and to extend benchmarking efforts across dermatology settings to guide system-wide improvements in care delivery and sustainability.

Background This Consensus Statement introduces a standardized framework, in a checklist format, to support future development and reporting of TDABC studies in healthcare, and to encourage their reproducibility. Additionally, it establishes the first formal networking of TDABC researchers through the creation of the TDABC in Healthcare Consortium. Methods A consensus group of researchers reviewed the most relevant TDABC studies available in Medline and Scopus databases to identify the initial elements of the checklist. Using a Focus Group process, each element received a recommendation regarding where in the scientific article section it should be placed and whether the element was required or suggested. A questionnaire was circulated with expert researchers in the field to provide additional recommendations regarding the content of the checklist and the strength of recommendation for each included element. Results The TDABC standardized framework includes 32 elements, provides recommendations where in the scientific article to include each element, and comments on the strength of each recommendation. All 32 elements were validated, with 21 elements classified as mandatory and 11 as suggested but not mandatory. Conclusions This is the first standardized framework to support the development and reporting of TDABC research in healthcare and to stablish a community of experts in TDABC methodology. We expect that it can contribute to scale strategies that would result in cost-savings outcomes and in value-oriented strategies that can be adopted in healthcare systems and institutions.
