Accounting at MacCloud Winery

by David F. Hawkins, Robert S. Kaplan and Gregory S. Miller

Abstract

Uses a fictional new winery to introduce accounting concepts and practices such as assets, liabilities, expenses, the matching principle, and contingent activities. Designed to approach the subject at a conceptual level, allowing class discussion to focus on the underlying thought process regarding accounting, rather than on "proper" numerical calculations.

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

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.

Objectives: To apply time-driven activity-based costing (TDABC) methodology to determine emergency medicine physician documentation costs with and without scribes.

Methods: Two research assistants shadowed attending physicians for a total of 64 hours in the adult emergency department. A tablet-based time recorded was used to obtain estimates for physician documentation time on both control (no scribe) and intervention (scribe) shifts.

Results: Control shifts yielded approximately 3 hours of documentation time per 8 hours of clinical time. When paired with a scribe, attending physician documentation decreased to 1 hour and 45 minutes during a shift and 15 minutes of post-shift documentation. The physician cost estimate for documentation without and with a scribe is 644 and 488 dollars, respectively.

Conclusions: TDABC methodology demonstrated that scribes afford a cost-effective solution to ED clinical documentation. The costing approach enables clinicians to understand utilization and cost of medical resource at a more granular level.

We describe a quality improvement initiative aimed at achieving interdisciplinary consensus about the appropriate delivery of extracorporeal membrane oxygenation (ECMO). Interdisciplinary rounds were implemented for all patients on ECMO and addressed whether care was consistent with a patient’s minimally acceptable outcome, maximally acceptable burden, and relative likelihood of achieving either. The rounding process was associated with decreased days on venoarterial ECMO, from a median of 6 days in 2014 (first quartile [Q1]–third quartile [Q3], 3–10) to 5 days in 2015 (Q1–Q3, 2.5–8) and in 2016 (Q1–Q3, 1–8). Our statistical methods do not allow us to conclude that this change was due to our intervention, and it is possible that the observed decreases would have occurred whether or not the rounding process was implemented.
