I've done a good bit of digging to show the point I'm trying to make.
Will include all links at the end.
Remember now, this policy is directed towards women, who already have insurance.
If the statistical representation of Hawaiian unplanned pregnancies is similar to the rest of the nation, women with insurance are the least likely to have an unplanned pregnancy, out of all groups of women.
The most likely were women on Medicaid/state insurance program, with uninsured being the next likely.
Also included, that of all pregnancies, both intended and unintended, only 14% were unwanted.
So the majority of the pregnancies cost, will be incurred anyway, at some time.
Next up is cost being a factor for not using birth control.
The Guttmacher institute highlighted that cost and access was only a problem for 12% of all women surveyed, that includes women who were insured and not insured.
The majority of unintended pregnancies, were women who were already using birth control and used it incorrectly (including men who improperly used condoms.)
Basically the only thing that I'm seeing that could have any real cost reduction for unintended pregnancies, is if women start to switch to longer term birth control methods, like the IUD, Depo Provara, etc.
The cost of those, is greater than your standard birth control pill or box of condoms.
If you include the now subsidized cost of women who use birth control correctly with this, most of those savings could evaporate and potentially increase total costs.
Especially if you include the fact that OBG's, drug makers, etc can now increase billing charges to insurance companies because they would have to cover it.
