Former Postdoc Kenneth Lopiano Speaks at RTP180

Dr. Kenneth Lopiano, co-founder of Roundtable Analytics and former postdoctoral fellow at SAMSI, spoke to a sold out crowd last night at the RTP180 event. RTP180 is a monthly after-hours get together where speakers spend about 5 minutes talking about a topic they are passionate about, and that highlights some of the research happening in the Triangle region. It’s kind of like a mini TED talk meets Pecha Kucha.

Lopiano spoke about the simulation model he and others developed to help ER departments become more efficient. You can read more about it here.

Some of the comments on Twitter included: @nxtstop1 “”Round table analytics” ~ does work in ERs using simulation models to determine best practice for that particular dept~

@Jnewbay “Emergency departments moving more efficiently? I’m in! Shorter wait times in the ER?

@bentanthony01 “ pitching at – Are you tired of waiting at Emergency Department? ED simulation models

@HealthView “We need actionable insights to healthcare data says Roundtable Analytics <Hear! Hear!”

Data-Driven Decisions in Healthcare – An Overview of the Opening Workshop

The following is from Ray Falk, from OptInference LLC, who participated in the opening workshop for SAMSI’s Data-Driven Decisions in Healthcare program.

I found the kick-off workshop, Data-Driven Decisions in Healthcare, tightly focused on methodologically tractable projects with ‘shovel-ready’ data sources, primarily in the areas of operational patient, provider, and (material) resource allocation and scheduling and patient-centered (personalized) effectiveness assessment.

Avi Mandelbaum

Avi Mandelbaum of Technion gave a lecture at the opening workshop.

Inference, analysis and control of service systems were developed via extension of existing results and observations from call center management (Avi Mandelbaum), including stabilization of performance under time-varying conditions (Yunan Liu).  Prodigiously comprehensive tracking of patient flows through the ICU (Carri Chan) and the remaining non-intensive departments of a hospital (Jim Dai) were related to specific insights regarding options for intervention (including proportional and absolute threshold effects), both for providers and patients.  An interesting discussion addressed dependence of service times on (new vs. readmitted) patient status (Guodong Pang).

Bob Obenchain

Personalized medicine was addressed from several perspectives, including heterogeneous treatment effects (with a heuristic re-sampling based approaches from Bob Obenchain and Sheldon Jacobson), appropriately targeted decision analysis based on high-dimensional modeling from large populations (centered on ROC curves from validation data sequestered from model development), and availability of comprehensive data, as well as methodologies for data acquisition and alignment, inference, and modeling(OMOP) (David Madigan, Patrick Ryan) .  Assessment and prediction from retrospective observational studies and tracking data was addressed via meta-analysis, propensity matching or weighting, and spontaneous event reporting (with no identifiable population at risk) (Alan Menius)

Guidance and policy for the national initiative in patient-centered evidence-based assessment of medical effectiveness was addressed via standards elaborated via PCORI (Constantine Gatsonis, Sally Morton).  Issues and perspectives included:
Value of Information for  prioritization, Efficiency of adaptive experimental design, individually heterogeneous treatment effects, observational vs. prospective randomized trials, data infrastructure (storage of electronic records and ontologies for integrated access), and technology assessment and dissemination, hyper-inclusive access to results for review (beyond standard publications in English).  An auxiliary resource is the Society for Medical Decision Making (Turgay Ayer).
