ORLANDO – Implementation of clinical pathways aimed at improving appropriate, evidence-based care for patients with metastatic non–small-cell lung cancer (NSCLC) reduces costs without negatively affecting survival, the Dana-Farber Cancer Institute’s experience suggests.
“At Dana-Farber ... we have looked toward pathways as a potential tool to help manage complexity and resource utilization,” senior author David M. Jackman, MD, explained at a symposium on quality care sponsored by the American Society of Clinical Oncology. “We see pathways as a patient-centered platform that provides real-time decision-making support across the continuum of cancer care. We think that these should be based on preemptive decision making, reflect current standards of care, incorporate feedback from which we can learn from our practice patterns, and support clinical research.”

After the customized Dana-Farber Lung Pathways were implemented in 2014, the cost of outpatient care per patient in the first year after diagnosis fell by about $17,000, or 25%, primarily driven by reduced use of antineoplastic agents, according to data reported at the symposium and simultaneously published (J Oncol Pract. 2017 Mar 4. doi: 10.1200/JOP.2017.021741). Meanwhile, median survival remained at about 11 months, even trending slightly upward.
“Frankly, I’d like to think that we were delivering reasonable and expert care prior to 2014, so I did not anticipate that we were going to see a major change in terms of improvement in survival. But it is important for us to make sure that as we implemented Pathways, there was certainly no decrease in such care,”said Dr. Jackman, medical director of Clinical Pathways at Dana-Farber and an assistant professor of medicine, Harvard Medical School, Boston.
He and his colleagues plan to expand Pathways to cover the full spectrum of cancer care at their center, encompassing medical, radiation, and surgical oncology, he said.
“We also think that pathways can have a major impact on things like symptom management and survivorship care,” he added. “And as we work to embed all of our trials within our Pathways system, and as we push to have our trials in our satellites and in our network affiliates, we hope that this combination of activity can help move us from being not just a good care network, but also a research network.”
The pathways will still have to address some of the thornier issues related to the value of care, Dr. Jackman acknowledged “It’s incredibly easy for us to look at two equivalent therapies in terms of toxicity and efficacy and pick the cheaper one. The harder conversations are to come, that is, what if something is x dollars more expensive and only improves things by a small number of months, is it really worth it?
“Finally, we hope that pathways can be an area for innovation, not used solely to manage costs and to make decisions based on yesteryear, but also to help us move forward and to be the watering hole where everybody comes, as we build out our system that is looking granularly at genomics in order to help match patients with trial opportunities, and for researchers, to help them find specific patients for their trials,” he said. “Pathways can potentially be the nexus where everyone comes and where doctors are informed in real time about opportunities for their patients.”
More evidence of benefit
The Dana-Farber study adds to others showing that the benefits of pathways are real and reproducible, according to invited discussant Thomas J. Smith, MD, professor of oncology and palliative medicine at Johns Hopkins Medicine in Baltimore.

“More importantly, I think, for patients, who are getting hit with these bills and might have a 20% copay, it’s going to reduce their copays and for all the right reasons,” Dr. Smith concluded.
Pathways development
In developing the pathways, Dana-Farber began with lung cancer in part because the center sees a high volume of patients with the disease. In addition, decision making for this malignancy is complex, and there was considerable variation in oncologists’ practices.
“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.”
