Smoking history- how does it tell me what I need to know?

I understand the "how to" of recording a patient's smoking history (# of packs per day times the # of years patient has smoked)....what I don't understand is this...as I view a patient history and see "19 pack year history," what does that mean? How do I discern how many packs/day x how many years? This is probably a simple thing that I'm making hard, but it just seems like it would be easier to record 2 pack/day x 12 years.... Can anyone explain? Thanks!

I actually work in psych ER where we get a lot of smokers (and other drugs!) and honestly we don't use that calculation. We just record how many packs smoked or cigs per day and maybe how many years-- its knowing how much they smoke that you need to know to be able to figure out what they need in terms of NRT--Nicotine replacement Therapy-- In terms of using this calculation for other purposes-- like maybe the damage done to lungs for a pulmonologist or something....don't know really how they use that data. But like said we use it for NRT. ..........??????

To me, as a nurse, it is merely a historical fact. In my years as a nurse I can also tell you that this person has a high risk of lung cancer and COPD. He probably has a hacking cough as well and I would assess for it.

It's a total measure, because the total number of cigarettes is more important than the length of time. You can get the same amount of damage from smoking a pack a day for 10 years as you can from smoking 2 packs/day for 5 years ... so both histories would equal 10 pack yrs.
