Lung cancer pathways reduce cost of care without compromising outcomes

“Our platform exists as an independent web-based system that currently lives outside of our EMR. Physicians can access this in real time, in the clinic room with the patient if they so choose,” Dr. Jackman explained. “From our EMR, we are flagged every time a provider orders a new start [of therapy], whether it’s IV chemo, oral chemo, or hormonal therapy. From our vendor, we receive granular treatment decision information made within the pathways system – information about the provider and site, information about the patients, their disease, and the line of therapy, as well as other important factors that drive decision making. Finally, from our clinical trials system interface, we can confirm trial enrollment data.”

Oncologists are free to leave the suggested pathway if their clinical judgment favors an alternate course, according to Dr. Jackman.

“We always want our physicians to feel comfortable treating the patients in front of them however they see best fit. If that means an off-pathway therapy, we want them to have the freedom to do that,” he said. “But we think one of the major tools of the pathways is to help capture the reasons why. So if they think it’s warranted and appropriate, go ahead, go off pathway, but tell us why you are doing it so we can learn from it.”

Using Pathways has not proved burdensome, according to Dr. Jackman. Navigating through the system requires about a minute or two, and use is required only when a patient is starting a new therapy, which typically occurs less than once per half-day clinic session.

Study details

In the study, he and colleagues compared costs of care in the first year after diagnosis of stage IV NSCLC between 160 patients treated at Dana-Farber in 2012 (before Pathways implementation) and 210 patients treated there in 2014 (after Pathways implementation).

“It should be noted that because we are a free-standing outpatient cancer center, all of the costs that we were able to gather are intramural and therefore related only to outpatient activities,” he pointed out.

The total annual costs of care per patient, adjusted for potential confounders (age, sex, race, distance to the institute, clinical trial enrollment, and EGFR and ALK status) fell by $17,085 after implementation of Pathways, from $69,122 to $52,037 (P = .01), he reported.

The largest source of cost savings by far, accounting for 73% of the total, was reduced use of antineoplastic agents (chemotherapy, biologics, and other anticancer agents). Cost for this component fell from $44,237 per patient to $31,846 (P less than .01).

“The majority of this savings came through a reduction in the use of what we considered unwarranted use of combination chemotherapy,” Dr. Jackman said. “In the first-line setting, we specifically went after the regimen of carboplatin, pemetrexed, and bevacizumab; based on our interpretation of the PointBreak study, we felt that that regimen did not bring additional efficacy but did essentially double drug costs. In going after that, we reduced not only use of that but also the subsequent use of pemetrexed plus bevacizumab maintenance. In the second-line setting, with the implementation of Pathways, we saw a decrease in the use of inappropriate platinum-based doublet therapy in those patients who had previously progressed on a platinum-based doublet.”

Median overall survival did not decrease and in fact increased slightly, from 10.7 months before Pathways implementation to 11.2 months afterward (P = .08). Corresponding 1-year rates of survival were 52% and 64%.

“We stand on the shoulders of those who came before us, who have also shown savings associated with implementation of pathways,” concluded Dr. Jackman. “But we hope that we add our voice and our data to this argument that pathways, I think, are a reasonable tool as we try to manage complexity and resource utilization. In addition, we do so without impinging upon clinical outcomes.”

The study was limited by its inclusion of only outpatient costs at Dana-Farber, he acknowledged. “You and we would be very interested in being able to know whether our Pathways implementation affected ED [emergency department] visits or hospitalizations. To that end, we are working with some of our regional payers to try to transparently share data around outcomes, costs, and usage, so that we can learn more in this regard.”

Dr. Jackman disclosed that he is an adviser or consultant to Bayer, Celgene, CVS Caremark, Genentech, and Lilly.
