The ASRA COAGS app has been updated with a universal code base and a fresh new look. This subscription-based app is $6.99/annually or free with ASRA Pain Medicine membership. The app transforms the American Society of Regional Anesthesia and Pain Medicine anticoagulation guidelines for Regional Anesthesia and Interventional Pain Procedures into a quick and easy reference for your practice. It provides rapid access to drug-specific summary information. This version combines the most current recommendations from two separate publications: 1. The 2025 guidelines “Regional anesthesia in the patient receiving antithrombotic or thrombolytic therapy: American Society of Regional Anesthesia and Pain Medicine Evidence- Based Guidelines (Fifth Edition)” published in Regional Anesthesia & Pain Medicine. 2. The 2018 Interventional Pain guidelines from the publication “Interventional Spine and Pain Procedures in Patients on Antiplatelet and Anticoagulant Medications (Second Edition); Guidelines From the American Society of Regional Anesthesia and Pain Medicine, the European Society of Regional Anaesthesia and Pain Therapy, the American Academy of Pain Medicine, the International Neuromodulation Society, the North American Neuromodulation Society, and the World Institute of Pain” published in Regional Anesthesia & Pain Medicine. The app provides direct access to both the regional guidelines and the pain guidelines, also allowing you to choose a default and focus on your specific practice area. Regional Guidelines: 1. Search for drugs by brand name or generic name. 2. Get recommendations based on the block type (e.g. neuraxial, peripheral, obstetric) and the intervention type (e.g. placing a block or removing a catheter). 3. Access more detailed information by using the Information "i" button: a. Mechanism of action for each drug. b. Executive summary for each drug. c. The full 2025 ASRA Pain Medicine regional guideline document. Pain Guidelines: 1. Search for drugs by brand name or generic name. Or start your search by procedure. 2. Get recommendations for: a. High, intermediate, and low risk procedures. b. Modifiers for patients at higher bleeding risk. c. Herbal medications. d. Antidepressant medications. e. When to restart medications after a procedure. 3. Access more detailed information for any drug by using the Information "i" button: a. Mechanism of action for each drug. b. Executive summary for each drug. c. The full 2018 ASRA Pain Medicine interventional pain guideline document. Members of ASRA Pain Medicine receive all society apps for free with their membership.

EVD educational toolkit is a clinician-facing reference on external ventricular drains (EVDs) and intracranial pressure (ICP) monitoring, designed for neuro-ICU and neuroanesthesia teams, nurses, and trainees. WHAT'S INSIDE • What is an EVD? Definition, common indications, and epidemiology • EVD Setup: leveling at the external auditory meatus, transducer safety, and drainage settings used in practice • ICP Waveforms: normal and abnormal P1/P2/P3 morphology with real bedside tracings • CT Imaging: expected catheter position and imaging examples • Transport & MRI Safety: a pre-transport checklist and MRI safety steps • Best Practices: do's and don'ts and CSF color interpretation • Clinical Pearls: concise, referenced teaching points • Types of EVD and EVD Systems: a photo library of devices and drainage systems • QI Metrics and EHR Alerts: suggested quality metrics, reportable events, and an example institutional EHR workflow • Educational videos, downloadable resources, and materials from the SNACC EVD Safety Campaign REFERENCED CONTENT Clinical content in the app is linked to published sources, including the SNACC perioperative guidelines for external ventricular and lumbar drains and the Neurocritical Care Society EVD consensus statement, with direct links to PubMed. Where content reflects one institution's practice rather than published evidence, the app says so. EDUCATIONAL USE ONLY This app is an educational resource. It is not a medical device, does not diagnose or recommend treatment for individual patients, and does not replace clinical judgment, institutional protocols, or manufacturer instructions. The app has no accounts and does not collect patient information. RESEARCH STUDY This app is part of a research study evaluating clinical implementation of the EVD Toolkit. The University of Washington Human Subjects Division reviewed the study and determined it exempt from further IRB review (STUDY00026573, approved 9/16/2026). Participation in the optional feedback survey is voluntary. Developed at the University of Washington.

Verdict
The clearest difference is rating: EVD educational toolkit at 5.0 against ASRA Coags's 1.3. EVD educational toolkit also leads on monetization model (free vs subscription). ASRA Coags's advantage is ratings volume (407 vs 2) and iOS requirement (13.4 vs 18.5). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
EVD educational toolkit holds the better App Store score, 5.0 against 1.3. That said, the two scores are not equally well evidenced: ASRA Coags has 407 ratings behind it against 2, so its average is the more settled of the two.
