Minimizing prostate cancer admissions via enhanced outpatient care: A model for savings.

Abstract

46 Background: Hospitalization is a major contributor to cost in oncology. Minimizing avoidable admissions can lead to substantial savings. Methods: We studied Medicare claims data from 160 admissions for prostate cancer (PCa) patients from 1/2012 to 5/2015. Admissions with the lowest 50th percentile of charges were assessed for being potentially avoidable by 2 independent chart reviews; remaining admissions were assumed to be unavoidable due to medical complexity. Common admitting diagnoses were targeted by theoretical care pathways designed to minimize avoidable admissions via expedited outpatient follow-up. We compared the cost of the avoidable admissions to that of implementing 3 such pathways then estimated the financial impact. Results: Total cost for all 160 admissions was $1,979,200. 25% of these admissions, accounting for $494,800, were deemed potentially avoidable. Our model exchanged each of these admissions for a routine clinic visit which led to an estimated $464,800 in savings, or a 23% improvement in total cost. The most common admitting diagnoses were fever (18%), pain (12%), and dehydration (8%). On review, 3/9 fever admissions in this set were deemed avoidable with 1 extra clinic visit, 3 with 3 visits, and 3 were unavoidable, yielding a 53% reduction in cost for this diagnosis. Similar analyses led to cost reductions of 75% and 66% for pain and dehydration admissions, respectively. Combining just these 3 theoretical interventions led to an estimated savings of $146,955, or a 7.4% improvement in total cost. Conclusions: A sizable portion of PCa admissions can be avoided, with ample savings, if a system is in place to provide the additional care that often exceeds the capabilities of a busy practice.
