Wow, timely -- I was just about to comment on a DQS post of yours asking about MDM, since I think the two are related. Nice job on the DQS webinar yesterday, btw; very, very interesting stuff. Started playing with it, but I suspect I got ahead of myself for my particular problem. I'd like to create a master physician data set from several different sources, each of which contains different parts of the puzzle (and overlapping parts). Matching these physicians up across sources, however, requires data cleansing, so I think DQS applies in the process. Seems like mine is a typical householding problem; any references you might suggest which will guide me through an appropriate process integrating MDM and DQS?

I don't have any specific references as far as your specifc goals are concerned but I do have several thoughts to offer. The first is that DQS and MDS are not integrated when it comes to the cleansing activity. Ideally, cleansing occurs before MDS ever sees the data so it is an external process. Specific to you scenario, householding to achieve a distinct list of physicians would be tough considering that different sources may report different addresses if the physician practices at multiple offices or practices. You would be better off using something like either an NPI number or state licenses #s to get to a distinct list. You could fall back on the address to identify potential dups but with the assumption that it may not be 100% reliable. I have quite a bit of experience in health care and so feel free to private message me if you want to discuss further.

Thanks for your input. I sent you a PM, but not sure it went through. I should clarify that I am seeking to make a list of physicians with _all_ their practice locations, not just an individual physician list. (I may be using the householding term wrong.) We have found that third party providers of this data are not very reliable, or are too expensive, so we are trying to create our own. Perhaps the impossible task, but gives me an excuse to use these cool tools. Given your experience in healthcare, do you have a recommendation on a reliable source of physicians and their office locations?
