HALEMedical and Data Sciences

Capabilities

Test-driven software and medical data sciences.

Three lines of work, one standard. We build test-driven software, data pipelines and secure environments health programs run on; we turn the data those programs hold into predictive models, analysis and multimodal AI; and we bring physician-led clinical services and advice to the programs that need them.

The consoles and product figures on this page are illustrative product concepts, not screenshots of delivered systems. The respiratory, Tampa Bay and research-funding charts are CDC’s and NIH’s own data, and each names its source.

Custom software & data pipelines

Software built for health programs that have to answer for it: applications and internal tools, data and analysis pipelines with full lineage, and APIs that modernize legacy service layers. Versioned data and code, documented decisions, automated tests, and interfaces designed to Section 508 from the first sketch — so a reviewer can trace every result back to its source.

Health systems design & interoperability

Data exchange is where health IT programs go to die. Hale MDS works natively in the standards — FHIR, HL7v2, X12, OMOP — to connect systems that were never designed to talk. On top of that plumbing we design the intelligence: clinical decision support at the point of care, and AI-driven medical systems that survive contact with government oversight — documented, monitored, bias-tested, and explainable to a review board.

Secure data platforms & hosting

Health data deserves infrastructure built for it. We design, build and run the platforms that ingest, process, and serve clinical and claims data at scale — and the research enclaves where sensitive datasets can be analyzed without leaving governed boundaries. Accreditation is treated as an engineering problem: controls as code, evidence generated automatically, environments reproducible from day one.

Life & health sciences R&D

Study design and analysis on data agencies already hold. From forecasting an outbreak to measuring whether a treatment worked: retrospective and observational research, clinical outcomes, epidemiological modeling, and health services research for government health programs. Scenario models that quantify what an intervention buys, time-to-event analysis that shows who benefits, and statistics rigorous enough to publish and reproducible enough to audit.

Health services research & methods

Health services research on access, utilization and cost, and the methods that make secondary data answer a question defensibly — phenotyping, confounding control, bias analysis, and privacy-preserving analytics. Data collected for care and payment was not collected for the question in front of you; the method is what closes that gap, and it is written down before the first query runs. Every workflow is reproducible end to end, because research that can't be rerun can't be trusted.

Clinical services

Physician-led clinical services for federal health programs: medical evaluation and screening, and behavioral and mental health services — documented for audit and for reuse, with the same measurement discipline as the rest of this page.

What we deliver

  • Medical evaluation and screening examinations
  • Behavioral and mental health services
  • Clinical review of records and cases
  • Clinical documentation built for audit and data reuse
  • Quality and outcome measurement for clinical programs
  • Clinical input to system and data design

NAICS 541690

Scientific & technical consulting

Physician-led advisory to federal health programs: framing the clinical question, designing the protocol that can answer it, and serving as principal investigator or subject-matter expert on the work that follows. The judgment being sold is clinical — what an outcome measure actually captures, which confounders matter in a population, and what a result does and does not license a programme to conclude.

What we deliver

  • Clinical advisory and protocol design for federal health research
  • Principal investigator and subject-matter expert support
  • Outcome-measure selection and endpoint definition
  • Study feasibility, sample-size and power assessment
  • Independent review of research designs and analytic plans
  • Translation of research findings into programme decisions

How we work

Compliance is part of the design, not a stage after it.

  • HIPAA

    Privacy by design

    De-identification, minimum-necessary access, and audit trails built into every data flow.

  • NIST SP 800-171

    Controls as code

    Security controls implemented as code with evidence collected automatically, so accreditation is not a retrofit.
