Willis, S. NLM Classification 2020 Summer Edition Now Available. NLM Tech Bull. 2020 Sep-Oct;(436):e4.
Beginning with the 2020 summer edition, the NLM Classification has a new look and feel. With this new design comes a new URL (https://classification.nlm.nih.gov/). The old URL (https://www.nlm.nih.gov/class) will automatically be redirected to the new one. The new site functions best in Chrome or Firefox.
The look may be different, but the organization structure of schedules and index pages remains the same. Some new features include:
For more details see the Help Instructions for the NLM Classification Public Pages.
The major focus of the 2020 summer edition was the systematic review of the following schedules: WD (Disorders of Systemic, Metabolic or Environmental Origin, etc.) and WO (Surgery). In addition to the systematic reviews of the WD and WO schedules, other minor additions and changes were made.
A partial review of the WD schedule was already conducted with the 2019 summer edition systematic review to consolidate certain subjects in the QW and other schedules. The review of the rest of the WD schedule was completed with the 2020 summer edition. As a result, the following changes were made:
WO 320 | Nerve block |
WO 502 | Surgical hemostasis |
WO 504 | Electrosurgery |
WO 508 | Ablation techniques |
WO 595 | Cosmetic techniques |
WO 662 | Tissue and organ procurement. Tissue donors |
WO 664 | Cell- and tissue-based therapy (works on stem cell transplantation classed in QU 325) |
WO 705 | Cold injury |
WO 720 | Asphyxia |
WO 730 | Multiple trauma |
WO 750 | Emergency Surgery |
WO 780 | War-related injuries (General) |
WO 810 | Stab wounds |
WO 840 | Electric injuries |
WO 140 | Surgical diseases (General) (Classify general works on prognosis and treatment of surgical diseases in WO 500. Classify works on surgery for specific diseases with the disease) |
WO 198 | Electrosurgery. Cautery. Laser and electrocoagulation (General) (Classify works on cautery in WO 508. Classify works on electrosurgery in WO 504. Classify works on laser coagulation in WO 511) |
WO 250 | Asphyxia. Methods of resuscitation (Classify general works on asphyxia in WO 720. Classify works on resuscitation in WB 106 [new number]. Classify works on respiration problems caused by anesthesia in WO 245) |
WO 290 | Rectal (Classify works on rectal anesthesia in WO 275) |
WO 297 | Muscle relaxants and tranquilizing agents in conjunction with anesthesia and analgesia (Classify works on muscle relaxants in QV 140. Classify works on tranquilizing agents in QV 77.9) |
WO 375 | Diagnostic and therapeutic anesthetic procedures (Classify works on nerve block in WO 320 [new number]. Classify works on anesthetics in QV 81) |
WO 515 | Regenerative medicine (Classify works on regenerative medicine in QT 110) |
WO 640 | Prosthesis in plastic surgery (Classify works on surgically inserted prostheses and implants in WO 162) |
Examples of additional changes made:
An analysis of diet terms was done by exploring the MeSH trees for Diet and Diet Therapy because not all the terms are in both trees. Decision: All Diet Therapy terms should point to WB. Terms that just tree under Diet can point to QT.
2 new numbers created:
2 numbers modified
10 new index terms added:
QY 70 was expanded to include administrative aspects of clinical laboratories including standards. A new number, QY 75 Laboratory Safety, was created specifically for safety in laboratories. Several index terms were modified to add sub-indexes about safety and administrative aspects. New term added to index: Laboratory Proficiency Testing.
Caption at WJ 303 was changed from Urinary Secretion. Anuria (General) to Diuresis. Renal elimination. Renal Elimination was added to index to point to WJ 303.
Reports of an administrative nature, regardless of how often they are issued, should be classed with the society. Edits were made to notes across all the schedules at form number 1.
The PDF version of the NLM Classification will be updated with 2020 winter and summer classification data in late fall 2020.
The NLM Classification poster has been revised with 2020 data. The 18" x 24" poster will be available for ordering in late fall 2020. To order, please contact the NLM Communications Team. An 8.5" x 11" high resolution version of the 2020 poster is available in PDF at https://classification.nlm.nih.gov/static/classification/pdf/nlm_classification_poster_2020.pdf.
The 2021 winter online edition will be published in late January 2021. It will encompass the additions and changes from the 2021 MeSH (Medical Subject Headings) vocabulary as evaluated for inclusion in the Classification index. All main index headings will be linked to the 2021 vocabulary in the MeSH Browser.
