The simple answer is no, you don't need to take lantrus too, but some people DO use Lantus with the pump, and you CAN use a hybrid therapy system. Here's why and how you do it.
Say you are using a pump and you need to disconnect for a very long time because you are [filll in the blank] participating at a wrestling tournament, on a whitewater adventure, scuba diving to 300 feet, etc.
if yout total basal is 12 units, your average basal rate is 0.5 units per hour. Most people during very high activity use about 20-30% of their basal rate, you program your pump to back down normally but for this special day/reason you want the pump off for hours and you don't want to chance DKA. in the morning you would shoot 4 units of lantus (this is a all day basal rate of 0.17 units per hour) of and set your pump to a temporary basal rate that is about 0.2 units per hour less than normal. this is easier with a pump that can calculate percent of basal.
now when it's your turn to dive to 300 feet, you take your pump off, your basal rate is automatically reduced because, with the pump off you are relying on the lantus you shot in the morning, you dive for as long as you want and never worry about DKA.
some people get into DKA very easily. A pump makes you MORE liable to suffer from DKA because there is typically only fast acting insulin in the pump. if there is a delivery problem you could be in real trouble in 2-3 hours. for THESE people, it is a good idea to mix their humalog (novolog etc) with REGULAR insulin in the pump reservior. Because regular can last 6 hours - you are way less liabel to get into trouble if you had an infusion set failure.
about 5% of pumpers mix their fast acting insulin with a medium acting insulin (insulinpumpers(dot)org) becasue of DKA. I don't, I use humalog only. I have never been in DKA in 31 years so maybe i am lucky.
regarding failure rates - people will tell you that pod failures are not uncommon (I said it that way on purpose). If you get a bad one, you rip it off and slap a new one on. you can't compare that failure rate with say the breakdown of a Ping - if you did the Ping would be way ahead. instead you would have to look at the Ping PLUS the infusion system versus the omnipod. if you compared that set you would probably find that the failure rates are similar. You get a bad infusion set or site - you rip it off and put in a new one. same same! =)
get samples and try them. sleep with the ping, sleep with a pod stuck to you. wear it around for a little while. Play with the interface thinggy. Make the sales people demonstrate how you set them up, fill the reserviors, etc. IMO that's the best way to test which one you like.
cheers and good luck.
