Understanding Active Medical Interventions: Treatments & Procedures

Active medical intervention = any deliberate clinical action intended to modify the disease process or alter the patient's physiological state.

Categories & Examples:

Category	Examples
Pharmacologic	Antibiotics, chemo, antihypertensives, biologics, vaccines
Surgical / Invasive Procedural	Appendectomy, CABG, stent, laparoscopy, joint replacement
Device-Based	Pacemaker/ICD, LVAD, insulin pump, DBS, stent
Energy-Based	Radiation therapy, ablation (RF, cryo, microwave), lithotripsy
Biologic / Cellular	CAR-T, stem cell transplant, gene therapy, fecal transplant
Rehabilitative / Functional	PT/OT/SLP, cardiac rehab, vestibular rehab, CPAP
Psychotherapeutic	CBT, DBT, EMDR, exposure therapy, psychoanalysis

Contrast: Passive / Supportive Interventions

• Observation, monitoring, comfort measures, palliative hydration/nutrition, advance care planning.
• Do not directly alter pathophysiology.

Decision Framework:

1. Diagnosis & prognosis — what is the natural history?
2. Evidence base — benefit magnitude, NNT, harm (NNH), guideline class.
3. Patient goals & values — cure, function, longevity, comfort, avoidance of burden.
4. Risk-benefit discussion — shared decision-making.
5. Feasibility — access, cost, caregiver support, comorbidities.

Active intervention is not automatically better. Sometimes the best intervention is not to intervene (watchful waiting, de-prescribing, goals-of-care alignment).
