FieldMedic is a clinical reference tool intended exclusively for use by trained medical professionals, expedition medics, wilderness first responders, and remote medical officers with appropriate qualifications for their intended scope of practice. By using FieldMedic, you confirm you meet these criteria.
FieldMedic is not a medical device as defined by the UK Medical Devices Regulations 2002 or EU Medical Device Regulation 2017/745. It does not perform diagnosis, prescribe treatment, identify causes of symptoms with clinical certainty, or replace the professional judgement of a qualified clinician. References to "likely cause" or "possible cause" in the symptom checker are pattern-matching outputs based on user-entered information — they are not diagnoses and must not be treated as such.
All clinical content — including drug doses, management protocols, evacuation criteria, and drug interactions — is provided for reference only and must be independently verified against authoritative sources (including the BNF, relevant NICE guidelines, and manufacturer information) before any clinical intervention. Clinical content has been developed in good faith against the authoritative published guidelines listed on this page. Despite systematic review, medical guidance changes frequently and errors may exist. All protocols and drug information must be verified by a qualified expedition doctor with knowledge of the specific patient, environment, and context before operational use.
The developer accepts no liability for any direct, indirect, incidental, or consequential loss or damage arising from use of, or reliance on, content within this app or website, to the maximum extent permitted by applicable law. Users are responsible for ensuring they have the training, competence, and authority to apply any clinical intervention described. Nothing in this disclaimer excludes liability for death or personal injury caused by negligence, or any other liability that cannot be excluded under applicable law.
In any emergency where professional medical help is available, contact your local emergency services immediately. This tool is intended for use in remote or austere environments where such help is not immediately accessible.
