Quest EHR Lab Interfaces

While at HIMSS I had the pleasure of spending some time talking with Rohit Nayak, VP of Physician Tech Solutions at Quest Diagnostics. Not only is Rohit a very nice gentleman, but he also provides a number of really interesting perspectives on the healthcare industry. Quest is obviously known in the lab world, but as I mentioned last year, Quest is shifting from being a lab company to a technology company. This is clearly seen by their Care360 EHR product.

At one point, Rohit and I started talking about Quest’s approach to interfacing with EHR software. When you consider that Quest has the lab results that many EHR companies want and now Quest is offering their own EHR it makes for an interesting situation. Rohit told me that Quest has 120 EHR interfaces. He told me Quest’s approach was to be open when it comes to sharing data.

Before I talk more about these interfaces, I think it’s worth commenting on the 120 EHR interface number. The number of EHR vendors is often debated and discussed. I personally like to use the 300 EHR companies number. I’ve seen some go as high as 600 EHR companies, but I think those people are counting any software regardless of if it offers a comprehensive EHR product. For example, they might include an ePrescribing app which is part of an EHR, but I wouldn’t count it in my number.

With that as background, I find the 120 EHR interfaces with Quest quite interesting. Outside of some very localized EHR companies, you’d think that most legitimate EHR companies would have been almost forced to build an interface with Quest. Although, someone did recently tell me that Quest and LabCorp only have 7% of the lab market so maybe I’m overstating EHR vendors need to interface with Quest. I’d be interested to hear from EHR vendors who don’t interface with Quest and why they haven’t yet done so.

Heading back to interfacing with Quest, I was interested in how Care360 EHR users that don’t use Quest for their labs would be handled. Say I was a doctor who used LabCorp for my labs, but wanted to use Quest’s Care360 EHR. Would Quest support a lab interface from Care360 to LabCorp? Rohit told me that Quest would have no problem integrating Care360 with Labcorp, but that LabCorp wouldn’t let them do it. Don’t you love competition?

Of course, I only had the chance to talk with Quest about this topic. I don’t remember ever even seeing LabCorp at HIMSS. Considering LabCorp hasn’t taken the EHR route directly that could be why. I’m not sure many LabCorp users would want to use the Care360 EHR, but it is interesting to consider.

Rohit and I also started an interesting discussion about how well EHR software is consuming the Lab data that’s being sent across these lab interfaces. I’ve asked him to do a guest post on the subject, so I hope to bring you that in the future. You can also check out this 5 EHR Questions with Rohit Nayak video I did while at HIMSS as well.

  • Along with the you forementioned fact that although Quest is a popular Lab it is not the only Lab but one of many in the country. Many areas may have a larger percentage of providers using Bio Ref or Lab Corp. Also I tend to believe cost may play a part as to why some EHR have not requested an interface. With Quest also developing their own EHR is it possible sales & use of Care360 reduces the need for many providers to have the Quest interface.

  • Have there been any updates regarding the possiblity of LabCorp interfacing with QUEST? I mean I have to tell you, we have Quest Care 360 EHR and it is hurting us A LOT not having LabCorp’s support. Half of our patient’s are in the EHR and the other half are still in paper charts – when patients change insurances which belongs to the opposing lab (example: someone who once had Aetna/Quest now has Coventry/LabCorp) it damn near kills us. So I was just wondering now that the Affordable Care Act is in place, any chance of these guys getting THEIR act together?
