Process Costing: Revolutionizing Hospital Operations And Efficiency

how would process costing effect a hospital

Process costing in hospitals is a complex and challenging task, as hospitals deal with intangible service products and variable costs. Accurate procedure costing is critical for hospitals to improve efficiency, decision-making, and transparency. The traditional volume-based costing (VBC) method is popular but often inaccurate, while more sophisticated methods like Activity-Based Costing (ABC) can be more precise but are also more complex and costly. Marginal costing can provide insights into unproductive resource utilization, but hospitals must also consider labour costs, equipment, and maintenance. Cost accounting systems are essential for effective cost control, and hospitals must adopt suitable methods to manage their operations effectively and provide the best care at the lowest cost.

Costing methods

Traditional Cost Accounting Systems:

Volume-Based Costing (VBC): This method allocates indirect costs to each service or unit in a hospital using a single indicator, such as labour hours or the number of patients. However, VBC often leads to rough and inaccurate results.

Activity-Based Costing (ABC):

  • Introduced in the mid-1990s, ABC recognises all cost-generating events or transactions as "activities" and assigns a specific cost driver to each activity. While more accurate than VBC, ABC is more complex and costly due to the extensive data collection required.
  • Simplified ABC (S-ABC): A modified version of ABC that reduces the number of cost drivers, making it simpler to perform while still achieving accurate results.

Standard Costing:

  • Average Costing: This method takes the total healthcare expenditure and divides it by the total number of services provided (output) to determine a cost per patient.
  • Per Diem Costs: Calculated by dividing total expenditure by the number of days of service, resulting in an average cost per day. However, this method may not account for differences in patient or provider characteristics.

Micro-costing (Bottom-up) and Standard Costing (Top-Down):

  • Micro-costing identifies the specific costs associated with individual cases, such as drugs, nursing services, equipment, and physician services.
  • Standard costing takes a top-down approach, which may not reflect important factors like staffing levels and intervention duration.

Accurate costing methods are essential for hospitals to improve their operations and maintain financial sustainability. By understanding the costs involved in delivering care, hospitals can make informed decisions, optimise resources, and provide transparent pricing to patients.

Costing methods for specific health services

Cost accounting is a specific type of accounting that focuses on accumulating, analyzing, and controlling the costs incurred to deliver a service. Cost accounting is especially important in the healthcare industry, where it is challenging to measure the costs of providing services.

There are several cost accounting methods that provide organizations with accurate estimates of the costs they incur in producing output. However, little is known about which of these methods are most commonly used by hospitals.

  • Traditional Costing is a methodology that allocates organizational overhead to a specific output based on a predetermined cost driver or a pre-determined percentage rate. This technique is easy to understand and apply and requires minimal financial and managerial investment. However, it has been criticized for failing to account for differences in product/service lines and marketing channels and for producing inaccurate representations of a product or service's true cost.
  • Activity-Based Costing (ABC) is a more precise and complex method than standard costing. It involves matching direct costs to products or services and allocating indirect costs after grouping them by activity. ABC was introduced in the mid-1990s and aims to provide more accurate results by recognizing all events or transactions that cause costs as "activities" and preparing a specific cost driver for each activity.
  • Time-Driven Activity-Based Costing (TDABC) uses a single activity measure, and this single cost-time relationship may not represent the actual cause-and-effect behaviour of the costs. It may be more relevant for small service firms, but it is not suitable for complex enterprises with different department outputs.
  • Performance-Focused Activity-Based Costing (PFABC) is a hybrid iteration of ABC that attempts to overcome some of the weaknesses associated with ABC and TDABC.
  • Ratio of Cost to Charges (RCCs) is a method specific to the healthcare industry. Hospitals participating in the Medicare program file annual Medicare Cost Reports, allocating overhead costs to clinical departments. Hospitals can then compute a department-level RCC by pairing cost estimates with information about the total charges for all services provided by that department. This RCC can be used to estimate the cost of providing services to an individual.
  • Bottom-up or micro-costing involves creating estimates or researching actual costs for every part of a service and then aggregating them to create a total service cost. This approach tends to be more accurate but demands more effort.
  • Top-down or standard costing is a simple and easy-to-use approach for building healthcare budgets and forecasts. The primary disadvantage is that the standards may not perfectly reflect actual costs due to significant cost variances driven by individual patient needs.

Marginal vs absorption costing

Hospitals require accurate costing to improve efficiency, decision-making, and transparency. Marginal costing and absorption costing are two methods that can be used to calculate the costs of hospital procedures. Marginal costing, also known as variable costing, only considers the direct variable costs of a product or service and not fixed costs. This method is often preferred for internal decision-making as it highlights the incremental costs of production. In the context of a hospital, marginal costing would involve calculating the direct costs of a procedure, such as the cost of medical staff, drugs, and equipment used during the procedure.

On the other hand, absorption costing, also known as full costing, assigns all direct and indirect costs to a product or service. This includes direct materials, direct labour, variable overhead, and fixed overhead costs. Absorption costing is essential for financial reporting as it aligns expenses with revenue recognition and ensures compliance with accounting standards. In a hospital setting, absorption costing would involve allocating all the costs associated with providing a medical service, including both the direct costs of the procedure and the indirect costs such as administrative staff salaries, rent, and insurance.

One example of marginal costing in a hospital setting is the calculation of the cost of a below-knee prosthesis. The marginal cost was calculated based on the time taken at each stage of production and the actual cost of materials. The labour costs were treated differently in marginal and absorption costing, resulting in two different costs for the prosthesis. Marginal costing focuses on the variable costs directly related to the production of the prosthesis, while absorption costing includes fixed overhead costs that are spread across all units produced.

Another study compared the top-down and bottom-up microcosting methods for hospital surgery services. The agreement between these two methods was found to be poor, with a correlation coefficient of 0.73. This highlights the importance of choosing an appropriate costing method for different levels of analysis. Additionally, the study suggested that the top-down method may not reflect important factors such as staffing levels and intervention duration, which could impact the identification and targeting of inefficient processes.

In conclusion, both marginal costing and absorption costing have their advantages and disadvantages in the context of hospital procedure costing. Marginal costing provides a clear view of the variable costs associated with a procedure, making it useful for internal decision-making. On the other hand, absorption costing ensures compliance with accounting standards and provides a more complete view of product costs, making it essential for financial reporting. Hospitals can benefit from using both methods to improve efficiency, transparency, and financial management.

Cost accounting systems

Cost accounting is the process of estimating and classifying the costs incurred by an organization. In the healthcare industry, cost accounting starts by organizing direct costs, such as medical supplies and labour costs, to create standard unit costs for each delivered service. It also requires identifying and applying the indirect costs that support patient care services, such as equipment costs and operating room time.

In traditional cost accounting systems, volume-based costing (VBC) is the most popular method. This method allocates indirect costs to each cost object (services or units of a hospital) using a single indicator, such as labour hours or revenues. However, this method often yields inaccurate results.

The activity-based costing (ABC) method, introduced in the mid-1990s, provides more accurate results. It recognizes all events or transactions that cause costs as "activities" and prepares a specific cost driver for each activity. While ABC is more accurate, it is also more complex and costly than traditional methods due to the extensive data collection required for cost drivers.

A simplified version of ABC, called S-ABC, reduces the number of cost drivers, making it simpler to perform while still achieving similar accuracy. This method has been applied in hospitals to estimate the cost of laboratory tests.

Accurate cost accounting systems are essential for hospitals to improve efficiency, decision-making, and transparency. Hospitals have been slow to adopt sophisticated cost accounting systems due to the high costs and limited benefits of service-level cost information. However, with increasing demands for price transparency and the rise of healthcare costs, cost accounting information is becoming increasingly crucial for hospital management and competition.

Clinical process cost analysis

The process of clinical process cost analysis typically begins with the creation of a comprehensive flow diagram that maps out each activity in the care process. The cost of each activity is then calculated, and these costs are linked to the corresponding activities. This methodology was applied to analyze the costs of treating lung cancer at an institution, with total costs ranging from $6,400 to $7,700. The primary cost driver was personnel time, accounting for 55% of the total expense, while 40% was incurred in the operating room. Interestingly, the cost of care decreased progressively during hospitalization, and the length of stay had minimal impact on the overall cost of admission.

There are various methods for calculating hospital costs, and the choice of method can significantly impact the results and subsequent decisions. Traditional cost accounting systems often use volume-based costing (VBC), which allocates indirect costs to each service or unit of a hospital based on a single indicator, such as labor hours or the number of patients. However, this approach can lead to rough and inaccurate results. A more accurate method is activity-based costing (ABC), where each cost-generating event or transaction is identified as an "activity," and specific cost drivers are assigned accordingly. While ABC provides more precise results, it is more complex and costly to implement due to the extensive data collection required for cost drivers.

To address the challenges posed by traditional ABC, a simplified version called S-ABC has been developed. This method reduces the number of cost drivers, making it simpler to perform while still achieving similar accuracy to the original ABC method. This simplified approach has been applied in laboratory test cost estimation, yielding promising results.

Accurate costing is essential for hospitals to make informed decisions and improve efficiency. Hospitals can identify areas of inefficiency and target them for improvement by adopting appropriate costing methods and conducting clinical process cost analyses. This, in turn, can lead to better resource allocation, enhanced patient care, and more effective utilization of funds.

Frequently asked questions

Hospital procedure costing is the process of identifying the inputs used in a hospital and applying the costs of those inputs to the delivery of care.

There are three main types of costs involved in hospital procedure costing: direct costs, indirect costs, and full costs. Direct costs are costs directly attributable to patient care, such as nursing services, drugs, and medical supplies. Indirect costs are those that are not directly related to patient care but are still necessary for the functioning of the hospital, such as administrative costs and overhead expenses. Full costs refer to the total of direct and indirect costs combined.

Accurate procedure costing improves efficiency by providing transparency and aiding decision-making. With detailed cost data, hospitals can identify areas of inefficiency and make informed choices about resource allocation and process improvement.

Common methods include volume-based costing (VBC), activity-based costing (ABC), and micro-costing or bottom-up costing. VBC allocates indirect costs to each service or unit using a single indicator like labor hours. ABC identifies each cost-generating activity and allocates costs using specific drivers for each activity. Micro-costing calculates the costs of individual patient cases by summing up all direct and indirect costs.

With increasing calls for price transparency, patients may start choosing healthcare providers based on cost. As a result, hospitals may experience pressure to set prices that reflect the actual costs of providing care. Process costing can help hospitals accurately determine these costs and make informed pricing decisions.
