What Changed

On July 21, 2026, the Defense Department's Joint Trauma System (JTS) published Spider and Scorpion Envenomation, Clinical Practice Guideline ID84, version 1. It sits in the envenomation section of the JTS guideline library next to Snakebite Envenomation (ID81), which was updated in April.

On its own, a spider and scorpion guideline is not headline news for most police departments. The pattern around it is.

What It Says

By our count of the JTS guideline index, nine of its core clinical guideline documents now carry 2026 dates, not counting hosted documents or military working dog guidelines:

  • Airway Management in Trauma (ID39), January 28
  • Pelvic Fracture Care (ID34), February 17
  • CBRN Injury Part I: Initial Response to CBRN Agents (ID69), March 31
  • Snakebite Envenomation (ID81), April 27
  • Tactical Combat Casualty Care Guidelines, May 1
  • Acute Extremity Compartment Syndrome and the Role of Fasciotomy in Extremity War Wounds (ID17), May 21
  • Dried Plasma in the Deployed Trauma System and Contingency Operations (ID103), June 9
  • Orthopaedic Trauma: Extremity Fractures (ID56), June 22
  • Spider and Scorpion Envenomation (ID84), July 21

The JTS also updated several military working dog guidelines this year, and its library includes a K9 guideline on arachnid and snake envenomation.

That is roughly one core guideline every three to four weeks, including the May update to the TCCC guidelines themselves. We are not summarizing the clinical content of the new envenomation guideline here. Medics and medical directors should read it at the source.

Why It Matters Operationally

Guidance changes. Training often does not.

It is easy for an agency to build a medical curriculum once, certify instructors on it and run it for years. Meanwhile the underlying guidance is revised on a steady cycle. An officer trained three years ago on a slide deck that was never updated may be carrying outdated habits into the field with full confidence.

The new envenomation guideline is a useful example precisely because it is niche. Most patrol officers will never need it. But K9 handlers, rural deputies, search teams and tactical teams working outdoors in parts of the country with venomous species might. The question is whether anyone at your agency would even know it exists.

ODM's Position

Position: Every agency that trains officers in casualty care should have a named person and a regular process for tracking guideline changes, deciding with medical direction what applies, and pushing those changes into training. Compliance hours are not capability, and outdated hours are worse.

Evidence: The JTS index shows a steady stream of new and revised guidelines in 2026 alone, including the core TCCC guidelines in May. Training that is not reviewed against that pace drifts out of date.

Strongest counterpoint: JTS guidelines are written for military medicine. They are not civilian protocols, and chasing every update can create confusion, churn and wasted training time. Civilian law enforcement has its own framework in Tactical Emergency Casualty Care (TECC), from C-TECC, and many changes, including this one, will not matter to most patrol officers. That is correct. The point is not to adopt every military change. It is to review changes on purpose, with a medical director, and to decide rather than drift.

What good looks like:

  • A medical director or physician advisor who reviews tactical medical protocols at least annually.
  • A designated training coordinator who watches JTS, CoTCCC and C-TECC releases and flags changes.
  • A short written "what changed and why" for instructors whenever the curriculum is updated.
  • Specialty-specific add-ons, such as K9 or rural and wilderness modules, where the risk justifies it.
  • Refresher training that teaches the current standard, not the one officers learned at the academy.

What Your Agency Should Do Now

  • Find out when your tactical medical curriculum was last reviewed against current guidance.
  • Assign ownership of guideline tracking to a named person, not a committee.
  • Schedule an annual protocol review with your medical director.
  • Ask K9, rural and outdoor units whether they have medical training matched to their actual environment.
  • Budget for curriculum maintenance, not just initial course delivery.

Bottom Line

A new spider and scorpion guideline will not change how most officers work tomorrow. The pace of change behind it should change how agencies manage their medical training. Somebody has to own the question of what changed, and whether your officers know it.
