why do we take history?
History taking is the initial step to reach a diagnosis, and sometimes you can reach a diagnosis by history only.
what does history taking need?
- good communication skills
- sufficient knowledge.
what are items of medical history?
- personal history
- Chief complaint
- Present history
- Past history
- Family history
what are the items of personal history?
Example: Male patient, named XXX, aged 55 year old, from Mansoura, working as a teacher, marned and has 3 offsprings with the youngest one is 6 year old, He is a cigarette smoker with smoking index 400
what is somking index?
smoking index is a unit for measuring cigarettes consumption over a long period
what does smoking index equal?
smoking index = Ciggarettes per day Γ years of tobacco use
