This dataset contains data in support of the LAU Collection Project.

It is used to store data analogous to Readmission to MedWard. For the usual medicine program collection we don't need to store this explicitly because we derive it from future or past records. The sample size for LAU Collection Project is too short to do it that way reliably, so we will store the data explicitly.

Data Collection

• For any record collected as part of LAU Collection Project, consider whether there is an indication of a previous admission for which this is a re-admission, or a subsequent admission that is a re-admission for this admission.
• To decide if something is a re-admission, follow the criteria in Readmission to MedWard

Data Entry Instructions

Follow the definition in Readmission to MedWard. If you find that either this admission is a re-admission, or that there is a re-admission following this admission, enter one of the following.

• Project: LAU Readm - Item: "has previous" - Date/Time: that admission's dispo_dttm
• Project: LAU Readm - Item: "has later" - Date/Time: that admission's service start_dttm
• Checkbox, Integer, Real, Comment: not used

Enter this even if the partner-record is also part of the LAU Collection Project; yes, we would be able to find that re-admission in our usual way, but having all the data coded the same way will make it more consistent to analyze.

Special case - both admission and re-admission are part of the LAU collection

Even if the first admission and the readmission are part of our current review, still enter the tmp project. This will make the stats more straightfwd.

Special case - previous unit is an inpatient location

If the previous location was an inpatient location then the record doesn't meet criteria for Readmission to MedWard, so don't mark it as a re-admission.

  • Readmission to MedWard says "Readmission is attributed to the site or hospital from which the patient was discharged. "; so we would not need site details for "has later" since <this site> would be deemed responsible and it doesn't matter where the pt ends up next. However, we might want site details for "has previous", even if we only did as little as "same" and "other". I decided not to implement this for now since it wasn't requested, just documenting the consideration
