Boston Children's Hospital: Measuring Patient Costs

by Robert S. Kaplan, Mary L. Witkowski and Jessica A. Hohman

Abstract

The case describes two pilot projects on applying activity-based costing to measuring the cost of treating patients. It presents process maps and financial data relating to the processes used during (1) an office visit to a plastic surgeon for three different diagnoses and (2) application and removal of three different casts in the orthopedic cast room. Students calculate and compare the costs and margins of the three procedures at the two different sites using the hospital's existing cost system and a proposed new system based on time-driven activity-based costing.

Boston Children's Hospital: Measuring Patient Costs (Abridged)

Robert S. Kaplan

The case describes a pilot project on applying activity-based costing to measure the cost of treating patients. After an overview of Boston Children's Hospital and its local health care market environment, the case presents process maps and financial data relating to patients making office visits to a plastic surgeon for three different diagnoses. Students use the hospital's existing cost system and a proposed new system, based on time-driven activity-based costing, to calculate and compare costs and margins of the three types of office visits.

Boston Children's Hospital Process Map Video

Robert S. Kaplan and Mary Witkowski

The 13 minute video simulates a discussion among orthopedic surgeons and cast room technicians about the processes and resources used when applying long leg casts for patients. The video should be used when teaching Boston Children’s Hospital (Abridged) case, #914-407, or the unabridged case, Boston Children’s Hospital: Measuring Patient Costs, #112-086. The video allows students to create a time-driven activity-based costing (TDABC) process map for two types of leg casts. Students should view the video when preparing the case. The instructor can elicit the process map, in real time, on a blackboard or white board, using 5-10 minutes of class time. The teaching goals are for students to learn that process maps – the key component in a TDABC model - are not difficult to create, and what appropriate level of detail and precision is required for a TDABC process map.

In 2016 the newly appointed surgeon general of the Navy launched a value-based health care pilot project at Naval Hospital Jacksonville to explore whether multidisciplinary care teams (known as integrated practice units, or IPUs) and measurement of outcomes could improve the readiness of active duty personnel and lower the cost of delivering care to them, their dependents, and local retirees. This article describes the formation of the project’s leadership structure; the selection of four conditions to be treated (low back pain, osteoarthritis, diabetes, and high-risk pregnancy); the creation of the care team for each condition; outcomes and costs measured; and the near-term changes in outcomes during the twelve-month pilot period. Patient outcomes improved for three of the four conditions. We describe factors that contributed to the project’s success. After the pilot concluded, the Navy combined the back pain and osteoarthritis IPUs into a single musculoskeletal clinical unit and established a similar IPU at another naval hospital and its clinics. The diabetes IPU was continued, but the high-risk pregnancy IPU was not. We offer several observations on the elements that were key to the success of the project, explore challenges and opportunities, and suggest that the pilot described here could be taken to greater scale in the Military Health System and elsewhere.

In 2016, the Centers for Medicare & Medicaid Services (CMS) launched its first mandatory bundled payment program, the Comprehensive Care for Joint Replacement (CJR) model, by randomizing metropolitan statistical areas (MSAs) into the payment model. The paper analyzed Medicare costs for beneficiaries undergoing lower extremity joint replacement between April 1, 2016, through December 31, 2017. The introduction of the CJR was associated with reduced Medicare Part A spending ($582 per episode, a 2.5% savings) largely through lower post-acute spending in skilled nursing facilities. The CJR hospitals had no significant differences in hospital length of stay, readmissions, complications, 30- or 90-day mortality, volume of episodes, or patient characteristics relative to the non-CJR hospitals. We conclude that mandatory bundled payments may help to change clinicians’ and facilities’ behavior without harming quality.

Time-Driven Activity-Based Cost Analysis for Outpatient Anticoagulation Therapy: Direct Costs in a Primary Care Setting with Optimal Performance

Robert S. Kaplan, Rohit A. Bobade, Richard A. Helmers, Thomas M. Jaeger, Laura J. Odell and Derek A. Haas

Objectives: To determine how overall cost of anticoagulation therapy for warfarin compares with that of Novel Oral Anticoagulants (NOACs). Also, to demonstrate a scientific, comprehensive, and an analytical approach to estimate direct costs involved in monitoring and management of anticoagulation therapy for outpatients in an academic primary care clinic setting, post-initiation of therapy.

Methods: Time-Driven Activity-Based Costing (TDABC) was applied in a population-based cross-sectional study at Mayo Clinic’s warfarin anticoagulation clinic. The study measured the personnel and supplies costs to monitor and manage anticoagulation therapy for 5,526 patients.

Results: The cost of warfarin management for patients who display unstable International Normalized Ratio (INR) is more than three times those who display stable INR over time. For complex anticoagulation patients, the total cost of medication and monitoring for warfarin anticoagulation therapy is similar to that for NOACs.

Conclusion: Despite warfarin being significantly less expensive to purchase than NOACs, overall warfarin management incurs higher costs due to laboratory monitoring and provider time than NOACs. NOAC treatment, therefore, may not be more expensive than warfarin therapy management for complex anticoagulation patients.
