Material directory, clinical, rights and interface changes are recorded here. Small typographic and styling changes may be grouped within a release.
· v3.7.3
Directory search and keyboard correction
Added a visible Search button and made Return submit the directory search.
An exact tool name, abbreviation or alias now opens that profile; broader searches move clearly to the filtered result count.
Made tool-name matching insensitive to capitalisation, spaces and punctuation, including 3D CAM, 3D-CAM and 3DCAM; 4-AT and 4AT; and NuDESC and Nu-DESC.
Review status: this is a targeted interface correction. The underlying clinical/content review remains v3.4.0.
· v3.7.2
UB-CAM and SQiD classification corrections
Classified UB-CAM as Episodic assessment, rather than an ultra-brief tool; its UB-2 first step remains separately classified as ultra-brief.
Classified SQiD as an informant tool alongside Episodic assessment, rather than a bedside ultra-brief tool.
Review status: these are targeted authorial taxonomy corrections. The underlying clinical/content review remains v3.4.0.
· v3.7.1
Category wording and A–Z date spacing
Shortened the assessment-category label to “Episodic assessment” throughout the public interface.
Separated each A–Z profile name, year and directory class with central dots.
Review status: this is a wording and presentation correction. The underlying clinical/content review remains v3.4.0.
· v3.7.0
Clearer categories and neutral tool comparison
Added a prominent homepage finder based on the ten categories in the 2020 Delirium Words classification, updated for the expanded directory.
Removed the selected general-hospital showcase and the dedicated comparison blocks for named tools.
Rebuilt Compare so readers choose any two or three profiles rather than being shown an editor-selected group.
Simplified the Taxonomy page around the same ten practical browsing categories and retained a clear note that categories overlap.
Added a prominent Classification panel to all 130 tool and context profiles, showing every applicable category and linking the ten main categories back to filtered results.
Review status: this is a navigation and presentation release based on the author’s published classification. The underlying clinical/content review remains v3.4.0.
· v3.5.0
Shorter profiles and direct access to tools
Rebuilt all 130 profiles around a compact panel containing the tool link, original or principal source, and up to two further early or canonical sources.
Moved official access routes to the top and updated links for 4AT, CAM-family tools, CAM-ICU, ICDSC, DRS-R-98, NuDESC and DOSS.
Displayed the complete 4AT under its CC BY 4.0 licence. Other instruments are linked rather than reproduced unless permission or an applicable licence has been confirmed.
Added checked Google Images searches for CAM, Short CAM, MDAS, CTD and NEECHAM. These are discovery links only; results may be unofficial or copyright-protected.
Replaced long access and review commentary with concise practical information. Copyright and citation detail remains available in collapsed sections.
Corrected the Watcha scale's original source to Watcha and colleagues (1992), retaining the 2010 comparison as later evidence.
Standardised public wording to use “directory” or neutral phrasing throughout the site.
Review status: source roles, selected access routes and representative image searches were checked on 29 July 2026. Linked material retains its own copyright and licence terms.
· v3.4.4
Layered taxonomy and assessment-language correction
Placed 4AT, CAM and 3D-CAM in the shared broad role “assessment / detection of current delirium”, while retaining screening and diagnostic terminology as searchable historical or source language rather than a hierarchy.
Removed the implied universal pathway from 4AT to CAM and applied the same clinical-context statement to all three tools.
Separated the base 3D-CAM assessment from the derived 3D-CAM-S and raw severity methods.
Reframed the former single “purpose” facet as grouped dimensions covering clinical role, temporal use, information source, administration, component or adjunct status, population or setting, and directory context.
Assigned every public record a deliberate primary role, including separate roles for experience and impact, adjunctive measures, retrospective ascertainment, aetiology support and contextual records.
Added a dedicated Taxonomy page with an accessible figure, two semantic tables, boundary cases, references and a prominent note that the classification is the author’s opinion rather than formal consensus.
Updated Home, Directory, Timeline, Compare, Choose, About delirium, Methodology, Patients & families and individual profiles to use consistent terminology.
Kept legacy ?cat=screening and ?cat=diagnostic links working by mapping them to the shared assessment category.
Review status: the change responds to the 28 July 2026 4AT/CAM taxonomy audit and a wider site-taxonomy review. It is an author-defined editorial classification, not a consensus statement or endorsement.
· v3.3.3
Deployment package and asset-routing maintenance
Corrected the theme archive root and versioned-asset mapping used by the managed WordPress deployment. Clinical/content review remained v3.1.2; no new evidence or taxonomy claim was made.
· v3.3.1
Evidence provenance, search and accessibility corrections
Corrected MDAS to the threshold-specific values reported in Breitbart 1997 Study 1 (MDAS ≥13: sensitivity 70.59%, specificity 93.75%, n=33) and added a matching structured diagnostic-accuracy record.
Corrected the CAM-ICU-7 evidence join so the 2017 severity-validation cohort and the 2024 diagnostic-performance study retain their own sources and denominators; separated patient and assessment denominators on other audited records.
Placed the source type, citation, year, denominator and reference standard immediately before each displayed headline metric; added a transparent 4AT denominator caveat reflecting the original article and corrigendum.
Improved exact-name ranking, Unicode and punctuation normalisation, governed clinical synonyms, common misspelling and mishearing recovery, out-of-scope MMSE/MoCA guidance and the distinction between direct and mention-only results.
Added programmatic dialog semantics and background inertness to the narrow-screen filter drawer while retaining Escape, focus trapping and focus return.
Expanded CSV export with profile, access, metric-source, DTA-count, content-version and export-date fields plus a data dictionary.
Added a profile-level safety notice, persistent Patients & families route, evidence glossary, explicit training field, adjacent NICE citations and point-of-use curator-interest notices.
Clarified 4AT release/publication chronology and AMT4's component status; qualified ICDSC original-study versus pooled figures; corrected stray purpose categories.
Corrected the CAC-B book citation exports, clarified the core-only CSV scope, hid the no-op checked-reference filter when all records are checked, and used page-level review dates in the sitemap.
Centralised public site-release and clinical/content-review labels, moved executable navigation/timeline code into versioned external scripts and removed unsafe-inline from script-src.
Review status: these changes respond to an independent simulated-user audit and automated regression testing. They do not constitute representative user research, formal accessibility certification or complete external clinical review.
· v3.2.1
Navigation and security maintenance
Corrected desktop and mobile menu wrapping, spacing, focus handling and resize behaviour.
Removed a retired external-domain link from the public build.
Changed consented analytics to report only the page path, never any URL query parameters or fragments.
Added script-safe data serialisation, outbound-link protocol checks, safe CSS tokens and spreadsheet-formula protection for CSV exports.
Added a restrictive Content Security Policy and further browser security headers; disabled the built-in file editors, XML-RPC and pingbacks, public REST user discovery and credentialed cross-origin REST access.
Added a standards-based security contact file and removed obsolete generated assets from prior releases.
Scope: this maintenance release changes deployment, privacy and interface safeguards; it does not claim a new clinical evidence review.
· v3.1.0
Second-wave clinical, privacy and accessibility corrections
Corrected SQeeC to “Simple Query for Easy Evaluation of Consciousness” and added CAM-ICU Flowsheet as a protected version within the CAM-ICU family.
Moved SDC and VAS-AC from the core count to historical or related context after rechecking their identity, intended construct and validation basis.
Added TDDS and TDDS-SF, DSNCPD-ICU, the Delirium Etiology Checklist and Delirium Item Bank as clearly labelled related measurement records.
Added a selected delirium risk-prediction collection with explicit eligibility and implementation cautions, including PRE-DELIRIC, E-PRE-DELIRIC, AWOL-S, PIPRA, DELIKT and Auto-DelRAS.
Revised DEL-B, DEQ, DDT-Pro and FMSE profiles and linked the 2026 s-DOSS scoring corrigendum. UB-2, DTS and SQiD remain in the directory; 4-DSD remains distinct from 4AT.
The revised count is 49 independent core families, represented by 82 core pages, plus 48 contextual pages: 130 public profiles in total.
Replaced duplicated runtime analytics code with one consent-gated site script, updated the privacy notice and stopped unrestricted WordPress/plugin head output from being inserted into reviewed static pages.
Added patient/family, governance, review-status, accessibility and risk-prediction routes; improved mobile navigation and filters, focus handling, table semantics, reduced-motion, forced-colour, print and no-JavaScript fallbacks.
Review status: structured internal adversarial clinical, rights, privacy, technical and interface review completed and rerun after deployment. Independent human multidisciplinary review, formal legal advice, real screen-reader testing and representative user testing remain outstanding.
· v3.0.1
Post-release clinical and editorial red-team corrections
Rewrote the homepage in a plainer reference-directory voice and removed the unsupported description of CAM as the most widely used tool.
Kept 4-DSD as a distinct instrument family, separate from 4AT, and retained the 1973 D-Scale as historical context at the start of the timeline.
Added the raw 0-20 3D-CAM severity method as a protected family version and K-APDS as an emerging general-ward screen.
Added E-CAM-S, VE-CAM-S, Buffalo Delirium Scale, SCDI, DBS-HCP, Mayo Delirium Prediction and DYNAMIC-ICU as emerging or contextual records. The public directory then included 83 core pages and 35 context pages, or 118 public profiles, while the independently counted core remained 51 families.
Corrected the structure, scoring, source and evidence fields for S-PTD, LSD-4, SOS-PD, K-ICDST, SDS-N and the EMS rapid checklist.
Separated software, data, article and instrument rights for the new records; no new form preview was embedded.
Retained substantive item and scoring commentary for SQiD, UB-2 and DTS under the site's limited-commentary policy.
Review status: internal source, clinical-taxonomy, rights, build and responsive-layout checks completed. This work is not an external Harvard, NIDUS or legal review, and it does not imply their endorsement.
· v3.0
Family-based directory and full profile rebuild
Replaced the single “87 definite tools” claim with separate counts for independent families, version/adaptation pages, workflows, emerging records and context.
Held MCV-NDRS outside the public directory pending verification of a canonical publication and instrument identity.
Corrected CAM-ICU-7, sspCAM-ICU, Short CAM, CAM-ED, VAS-AC, CAC-B, DEL-S, s-DOSS, DEMS, FIDDI, CAM-ICU Plus, CAM-IMC and other re-adjudicated profiles.
Separated post-anaesthetic emergence measures, adjunctive/component tests, chart methods, prediction rules and emerging technologies from the independent core-family count.
Added or classified Delirium Caregiver Questionnaire, DelApp-ICU, 3D-CAM-S, CHART-DEL-ICU, Delirium Motoric Checklist, Abnormal Signature Test, DeltaScan, Delirium Frontal Index, eDIS-MED, NOVAD, AiD-DST and CAM-ICU-10 with evidence-stage caveats.
Added structured instrument-access and rights states to every record. Corrected 4AT and RADAR licence/attribution data, removed bare “Free” labels, and separated forms from papers, validations, secondary summaries and rights evidence.
Rebuilt the homepage proposition, audience routes, directory filters, mobile filter drawer, A–Z default, Choose links, comparison links, timeline controls and error page.
Added progressive directory rendering, static-asset caching, accessible navigation states and automated structural checks.
Review status: internal clinical/source, rights, build, link, responsive-layout and automated accessibility checks completed. Full independent human clinical adjudication, screen-reader testing and task-based user testing remain outstanding and are not implied.
· v2.9.1
Deployment repair
Corrected the WordPress/10Web routing and static-asset deployment used for the v2.9 release, then verified the public routes. No change to the scientific taxonomy was claimed in this maintenance release.
· v2.9
Timeline and tool profiles
Added the earliest-first timeline, starting with the 1973 D-Scale as historical context; expanded individual profiles; and removed 3D-CAM from the homepage’s “widely used in general hospital care” group. The subsequent v3.0 audit supersedes the former single-count taxonomy.
