The MDS 3.0 used during the RAND research and pilot study was very different than what we have now. It had less data items, easy to complete and understand ADLs, lookback on most items was 5 days (it takes almost 25% more time if the lookback is 7 days), special treatments/programs had a 14 day lookback (regardless of setting) and other variations. Nurses received extensive training by psychology professionals on interviewing techniques. The study had no mention of scheduling/completion "hassles" because the nurse completed the entire MDS in most cases.
SO YES--the originally tested draft MDS 3.0 (full--no RAPs/CAAs) took less time than the MDS 2.0 did. The RAND report can be found at

Then CMS added and changed particular data items and added multiple new payment assessment types. Most (if not all) of the additional and changed data items were in response to MEDPAC recommendations for "more accurate" MC PPS reimbursement. The discharge "assessment" type was added to try to capture discharge status for potential QMs and upcoming P4P initiatives (but falls short, as the resident status is NOT the status AT DISCHARGE--it includes the same lookbacks and is not useful to any receiving facility). Oh yes--On/Off hospice requires a significant change comprehensive assessment even if one was completed 4 days ago, all orders and CP were changed to reflect the resident's terminal status and care, and included that hospice would begin when family returned from vacation to sign the hospice option form. Despite skip patterns, there are more data items on the current MDS 3.0 than the MDS 2.0.
We all know the outcome--more data items, more assessments, more complicated scheduling, less time for planning and providing care and less time to complete an "accurate" assessment.
The times mentioned are about what my many colleagues have reported (and does include some "hassle" time)--but does not include the time spent by other professionals.
