Questions about the Inputevents table [MIMIC-IV] #1141
-
|
Hi! I have some questions about the Inputevents table. It'll be really appreciated if you could help me. (1) I noticed that there is a column called statusdescription in the Inputevents table. The document said "STATUSDESCRIPTION states the ultimate status of the item, or more specifically, row." But I feel it's kind of hard to understand this statement. Does it mean that the labeled status was what happened after the endtime of that row? For example, if the status was "Changed", was the delivery changed after the end time? Or it might be changed at any time point between starttime and endtime? (2) Another question is that I find the ORDERCATEGORYDESCRIPTION of many rows are labeled as continuous, but the endtime - starttime is 1. According to the document, "A bolus will be listed as ending one minute after it started, i.e. ENDTIME: STARTTIME + 1 minute". I'm wondering whether those rows are bolus or continuous.
(3) I found that some records in inputevents are not in emar table or prescriptions table. Were these drugs administrated without prescriptions? If those tables have different records, which one should I use? Thank you very much!!!! Qinyu |

(1) Row means each row of data, the same meaning as the word item. So I would say at the end. (2) Basically, bolus, non-iv meds, and drugs don't have duration information. 1 is like a placeholder, doesn't do indication the actual duration. (3) Inputevents are documented specifically for ICU patients; emar and prescription are for all hospital patients and from a different information system. Unfortunately, there are not 100% matched. So which one to use really depend on what information you are trying to get. If you would like to investigate fluids given in the ICU, use inputevents. |

Hi! Thank you for your reply! I'm still kind of confused about the second question. Indeed, "bolus, non-iv meds, and drugs don't have duration information. " Many thanks!! |

Since those drugs are often given in a short time period, the time and rate variable wasn't documented the same as other IV drugs. This is just how the data is documented. The time you calculated doesn't mean the drug is given in exactly 1 minute, I would keep starttime or charttime and ignore the endtime and rate, also keep the volume. |
