This article is about time-dependent Drug-Drug interactions or (TDDIs) happening as a result of a combination of drugs being used together. Different medications were being administered to close together (time wise). There were studies done to see what the time intervals were pertaining to the administering of medications.
The studies were done at different times. Once the studies were complete, the results were discussed with the nurses. The nurses were told to let the ordering physician know when their was a discrepancy. The pharamcists wanted the information corrected on the CPOE, but felt it was more important to have the medication corrected on the actual chart so when the patients go to various departments or other appointments, the information would be correct.
Over 4 study periods, over 1,000 TDDI alerts were logged. In about a months time, the number of TDDIs had decreased from about 56% to 36%!
In conclusion, the TDDIs in the first study were more effective than the other study. The pharmacy technicians would often relay the TDDI information to the clinical pharamacist, so therefore, many times the physicians had no clue there were errors.
