Sources and Review Process

This page explains how QuickMedCalc selects sources, identifies formula versions, implements calculations, tests software behavior, communicates limitations, and handles corrections.

Current review status

All 89 current public calculator pages have completed the current source, formula-or-score, implementation, and regression review baseline. This is a version-specific and time-specific baseline, not a promise that every page remains current forever. Pages are reviewed again when relevant sources, guidelines, formulas, shared code, or reported defects change.

QuickMedCalc is developed and maintained by an independent developer. Test types and test counts vary with formula complexity, so a completed baseline does not mean every page uses identical test cases. Medical content is not independently reviewed by a physician.Software and regression testing is not clinical validation.

Source hierarchy and version control

Original and official sources are preferred. Secondary summaries may help locate a source, but they do not replace the source that defines a formula, score, or current rule.

  1. Current official policies, regulatory rules, or professional guidelines when a tool depends on a current operating rule.
  2. The original paper that defines the formula or scoring system.
  3. Validation papers, corrections, later formula revisions, or official technical notes.
  4. Manufacturer information when medicine, product, or device information is genuinely relevant.
  5. Historical primary sources when a page explicitly reproduces a historical model.

Publication date, version, intended population, model endpoint, and current status are checked. Historical models may remain available for clearly identified reproduction purposes, but the page must label the historical version and explain a current replacement when one exists. A stable public link to the original or official source is provided when available.

Source and implementation checks

Source and content check

This check compares the cited model with the page's formula, inputs, population, timing, thresholds, and limitations.

  • Source authenticity and current status
  • Formula or score version
  • Constants, coefficients, and branches
  • Input definitions and units
  • Intended population and exclusions
  • Measurement or specimen timing
  • Observation window
  • Thresholds, boundaries, and page limitations

Implementation and regression check

This check covers implementation, result communication, safety boundaries, and regression coverage against cited sources.

  • Whether the cited source actually supports the page
  • Updates, corrections, or a current replacement model
  • Formula and unit implementation
  • Threshold meaning and result presentation
  • Foreseeable misuse risks
  • Regression-test coverage

These checks describe the source and software work; they are not a second review layer.

Formula and software implementation checks

  • Formula structure and constants
  • Conditional branches
  • Input names and definitions
  • Inclusive and exclusive boundaries
  • Unit conversions
  • Age, weight, and published sex-variable meaning
  • Specimen and measurement timing
  • Observation windows
  • Missing or not-assessable items
  • Minimums, maximums, and model-defined clamping
  • Rounding stage and display precision
  • Representative examples
  • Boundary regression tests
  • Error states and stale-result clearing
  • Full regression after shared-code changes

A cutoff, category, diagnostic label, or treatment implication is displayed only when it belongs to the cited model or applicable authoritative guidance. QuickMedCalc does not add a threshold merely to make a result easier to classify.

Result communication and misuse prevention

Clinical professionals are the primary audience, while non-professional adult users should still be able to understand what a tool does and does not do. Plain-language explanation cannot omit the formula version, units, intended population, or important limitations.

Result cards must not present a calculation as a diagnosis or move directly from neutral arithmetic to treatment, prescribing, disposition, or referral. Historical and current models must be distinguished. Tools with similar names must explain differences in population, endpoint, or time window. Pages identify foreseeable ways a result could be misapplied and explain the relevant population, timing, measurement, and interpretation limits.

Review the medical-use boundaries

Role of AI and automation

AI-assisted tools and other software may support source discovery, comparison, coding, test generation, regression checking, and editing.

AI is not a physician or an independent medical reviewer. Automated tests verify implemented formulas, boundaries, error handling, and representative examples; they do not prove clinical applicability. Search results and model answers do not replace original sources. The independent developer remains responsible for publication, changes, and corrections.

When a page is reviewed again

  • An official guideline, policy, or regulation changes
  • A formula version changes
  • An original paper receives a correction or later revision
  • Relevant manufacturer information changes
  • A user reports a formula, unit, source, or explanation problem
  • The calculator registry changes
  • Shared calculation, unit, or result components change
  • A test fails or a production regression is identified
  • A historical model is not clearly distinguished from a current model

Pages are not promised simultaneous review on a fixed calendar. Pages affected by a change are prioritized. After review, the date, version explanation, sources, and tests are updated as applicable. Historical models may remain for explicit reproduction purposes when they are clearly labeled.

Corrections process

  1. Record the calculator and the specific reported problem.
  2. Attempt to reproduce the issue.
  3. Check the original or current authoritative source.
  4. Correct the formula, unit, boundary, explanation, or citation as applicable.
  5. Add or revise regression tests.
  6. Update the page date, version explanation, and references.
  7. Run affected tests and the full regression suite again.

Issues with potential medical-safety impact are prioritized for verification. No fixed response or correction time is promised.

Report a medical-content or calculation issue

What this review status does not mean

  • Medical content is not independently reviewed by a physician.
  • It does not mean endorsement by a hospital, university, professional association, or regulator.
  • It does not mean a formula is valid for every patient or setting.
  • Software testing is not clinical validation.
  • Citing a paper or guideline does not mean its authors or institution endorse this implementation.
  • It does not represent medical-device registration, approval, or certification.
  • It does not provide diagnosis, prescribing, treatment, monitoring, or disposition advice.

The Medical Disclaimer is the primary medical-use boundary. The Terms of Use provide additional legal terms.

Editorial independence

Advertising does not determine calculator selection, formula version, calculations, explanations, sources, or correction priority. QuickMedCalc does not accept paid calculator placement or sponsored clinical recommendations.
