1. Analysis of large claims databases. My early work focused on analysis of Medicare claims data to study patterns of treatment and diagnosis of breast cancer and ductal carcinoma in situ (DCIS). At the time, there was much uncertainty about choice of optimal DCIS treatment compared to early invasive breast cancer, because of limited randomized trials. We therefore expected higher variability in DCIS treatment over time. This work included a novel study evaluating variations and variability of DCIS treatment to see whether treatment patterns became more stable over time as treatment patterns had for early invasive breast cancer. Several algorithms have been developed over the years to identify new breast cancer cases in Medicare claims data; we evaluated those for their effectiveness on newer data, and found they did not hold up as well as might be expected. I have been involved advising junior faculty on their analyses of large claims databases and contributed to several papers, including one that considers imaging rates for prostate cancer in the United States. Finally, I have started working with all-payer data, such as the California Healthcare Cost and Utilization Project data focused on orthopedic surgery.

2. Large database analyses using econometric methods. Given that large observational databases are retrospective in nature, I focused my analytic efforts on using complex econometric methods to account for selection bias, or confounding by indication, in several studies. This body of work includes comparisons across methods to drive optimal model choice, given presence or severity of selection bias. My first paper in this area was a novel approach to estimating DCIS treatment effects from observational data. I implemented a modification of the trivariate probit model, which includes exclusion restrictions (similar to instrumental variables in the linear framework). The work showed the bias inherent in estimating treatment effects from observational data when not accounting for selection bias. This work built the analytic framework for a collaborative project using clinical data abstracted from charts of patients with DCIS. Finally, I undertook a study to assess the effect of suboptimal radiotherapy for women with DCIS or early invasive breast cancer. We used a standard model and the (econometric) bivariate probit model to account for patients’ differing propensities for receiving delayed or incomplete radiation treatment. We found the more sophisticated model was not necessary in this case due to limited presence of selection bias.

3. Cost-effectiveness research. Another major contribution is to the field of cost-effectiveness research. I published applied analyses that followed national guidelines for conducting such analyses. One used rigorous methods to evaluate the cost effectiveness of breast cancer radiation treatments, incorporating claims-based analyses into estimates for treatment effects. We showed that for women who might be more likely to have a delayed course of radiation, a shorter, accelerated course would be more cost effective due to higher recurrence rates associated with delayed treatment. A second paper was driven by the uncertainty surrounding use of pharmacogenetic tests prior to chemotherapy regimen choice. Here, we developed a model focused on this uncertainty and showed that without knowing the impact of a dose reduction of irinotecan for metastatic colorectal cancer, we were quite uncertain about the benefit of using a pharmacogenetic test that predicted a patient’s sensitivity to irinotecan. I also have thought deeply about how cost-effectiveness research has been used. One paper here focused on applying value frameworks from the American Society of Clinical Oncology (ASCO) and the European Society for Medical Oncology(ESMO) to quantify the benefit of antineoplastic drugs in the face of rising costs. We applied these frameworks to drugs approved by the US Food and Drug Administration(FDA) over 12 years, and examined relationships between costs and benefit. The analysis hihglighted the heterogeneous benefit of new medications and the challenge of creating a unified concept of drug value. Drug benefit does not correlate with cost and the number of high cost/benefit outliers has increased. A second paper listed here evaluated how sensitivity analyses of variables such as quality of life, cost, and discount rate would change published studies’ intervention recommendations. We showed that sensitivity analyses for economic parameters are widely reported and often identify whether choosing different assumptions leads to a different conclusion regarding cost effectiveness; however, the review and analyses showed that study quality varied dramatically. Finally, I am co-I on six grants to oversee and manage cost data collection and cost-effectiveness analyses of healthcare interventions and have conducted or advised on several cost-effectiveness analyses and cost analyses of large databases.

4. Qualitative healthcare research. Conducting qualitative research in healthcare can elucidate subtle distinctions in attitudes and decision-making. In order to inform a study on the diffusion of new technology, I sought to understand the nuanced decision-making process that physicians experience when deciding whether to adopt a new technology in their practice. This qualitative analysis of interviews with surgeons and radiation oncologists highlighted several important factors important to the process, including physician incentives (financial and reputational), practice location (rural versus not), level of scientific evidence available, and social pressure. I also helped with a project focused on ethnic minorities and understanding reasons for their employment changes following a breast cancer diagnosis, which concluded that employer support services during treatment could improve attitudes towards returning to work.
