tegevus, mille korral on küll valitud sobiv ravimeetod, kuid esinevad tüsistused, mida oleks saanud vältida
occurs when an appropriate process of care has been selected but a preventable complication occurs and the patient does not receive the full potential benefit of the service
Väärkasutuse näideteks on kirurgilise ravi välditavad tüsistused, allergilise reaktsiooni tekkine ravimi manustamise järgselt, kuigi patsiendi ravimiallergia oli teada või pneumotooraksi tekkimine, kui tsentraalveeni kanüüli paigaldab iseseisvalt väheste kogemustega töötaja.
Avoidable complications of surgery or medication use are misuse problems. A patient who suffers a rash after receiving penicillin for strep throat, despite having a known allergy to that antibiotic, is an example of misuse. A patient who develops a pneumothorax after an inexperienced operator attempted to insert a subclavian line would represent another example of misuse.
