Descriptive analytics
Summarizes historical data to answer what happened, using reports, dashboards, and aggregate statistics; it is the base level of the analytics maturity hierarchy.
Predictive analytics
Uses historical data and statistical or machine-learning models to estimate the likelihood of future outcomes such as readmission, cost, or disease onset.
Prescriptive analytics
Recommends specific actions by combining predictive models with optimization, rules, and constraints, such as prioritizing which patients receive care-gap outreach first.
HITECH Act
A 2009 US law that funded EHR adoption through incentive payments tied to meaningful use criteria and strengthened HIPAA privacy and security enforcement.
HEDIS
The Healthcare Effectiveness Data and Information Set, an NCQA measure set used to compare health plan performance on preventive care and chronic disease management.
LOINC
A standard vocabulary for laboratory tests and clinical observations that enables interoperable exchange of test names, units, and results across systems.
SMART objectives
Criteria stating that an objective must be Specific, Measurable, Achievable, Relevant, and Time-bound so that progress can be objectively evaluated.
Gap analysis
A comparison of current-state performance against the desired future state that quantifies the difference and identifies actions required to close it.
MoSCoW prioritization
A scoping technique that sorts requirements into Must have, Should have, Could have, and Won't have categories to force explicit priority decisions.
Requirements traceability matrix
A table mapping every requirement to its design, build, and test evidence so that nothing is dropped and scope changes remain visible.
Return on investment
ROI equals benefit minus cost, divided by cost, expressed as a percentage; it states the net value of an initiative relative to its cost.
HL7 version 2
A pipe-delimited messaging standard widely used for admission, discharge, transfer, order, and result messages; trigger events such as ADT^A01 signal an admission.
FHIR
Fast Healthcare Interoperability Resources, a RESTful API standard that exchanges health data as modular resources such as Patient, Encounter, and Observation.
Master patient index
An enterprise index that links records belonging to the same person across source systems using deterministic or probabilistic matching algorithms.
Deterministic matching
A record-linkage method that links two records only when specified identifiers agree exactly, giving high precision but missing records with data entry variation.
Data profiling
Systematic analysis of source data before use to assess completeness, uniqueness, validity, consistency, and distribution, revealing quality problems early.
Sensitivity
True positives divided by true positives plus false negatives; the proportion of people who truly have the condition that the test correctly identifies.
Positive predictive value
True positives divided by all positive results; the probability that a positive result is correct, which rises and falls with disease prevalence.
Confidence interval
A range around a sample estimate that would contain the true population value in a stated proportion of repeated samples; 95% is the conventional level.
Age-sex standardization
A method that re-weights rates to a standard age and sex distribution so populations with different demographics can be compared without distortion.
Statistical process control
Use of control charts with limits typically set at three standard deviations to distinguish common-cause variation from special-cause variation over time.
Confounding
A third variable associated with both the exposure and the outcome that distorts the observed relationship unless it is adjusted for in design or analysis.
Small number suppression
Masking cells with very low counts, commonly fewer than eleven, when publishing aggregate health data to reduce the risk of re-identification.
Benchmarking
Comparing a measured performance against an external or internal reference, such as a national percentile or peer group, to give the result context.
Operational versus strategic dashboard
Operational dashboards track daily or real-time tactical metrics, while strategic dashboards report periodic key performance indicators tied to organizational goals.
Data storytelling
Structuring an analytics report as context, key insight, and recommended action, sequenced and worded for the specific audience's decision needs.
Run chart
A line plot of a metric over time with a median reference line, used to reveal trends, shifts, and patterns without statistical control limits.
Data steward
A role accountable for day-to-day data quality, definitions, and appropriate use within a business domain, working under the authority of the data owner.
Data lineage
The documented path of a data element from source system through each transformation to the final report, supporting traceability and impact analysis.
Role-based access control
A security approach that grants data permissions according to job function rather than to individuals, supporting the HIPAA minimum necessary standard.
Business associate agreement
A HIPAA-required contract in which a vendor that handles protected health information for a covered entity agrees to safeguard it and report breaches.
Breach notification rule
Requires a covered entity to notify affected individuals without unreasonable delay and no later than sixty days after discovering a breach of unsecured PHI.
