• Definition2 : Percent of total discharges to ward, home and elsewhere

Significance

Unplanned readmissions are associated with worse patient outcomes. Most factors associated with an increased risk of readmission are patient and admission-specific. System related risk factors include discharge at night and ICU occupancy at the time of discharge. Readmission may reflect premature transfer out of ICU due to errors in clinical judgment or system constraints.

Sampling Plan / Procedure

Inclusion Criteria

• Definition1 :100% of all ICU patients discharged to ward
• Definition2 :100% of all ICU patients discharged to ward, home or elsewhere

Exclusion Criteria

• Definition1 & 2 : Excluding patients with planned and scheduled surgery (e.g. Admit Type for APACHE II is not 'Elect.Surg' ) in the count of readmission.
• Definition2 : Excluding patients who left AMA or palliative in the count of readmission.

Definition and Derivation

• Definition1 : Number of ICU readmission within 72 hours per 100 discharges to ward
• Definition2 : Number of ICU readmission within 72 hours per 100 discharges to ward, home or elsewhere

Numerator

• Num1 = Number of ICU readmission within 72 hours coming from ward
• Num2 = Number of ICU readmission within 72 hours coming from ward, home or elsewhere

Denominator

• Denom1 =Total Number of discharges who went to ward
• Denom2 =Total Number of discharges who went to ward, home or elsewhere

Formula

Readmission Rate(%) = Num / Denom * 100

Example

• Time Reference: Discharge Dates from Jan 1, 2017 to March 31, 2017
• Total readmission within 72 hours coming from ward= 5
• Total discharges who went to ward = 102
• Readmission Rate(%) = 5 / 102 * 100= 4.9 %

Data Sources

The following fields from L_Log table are being used

• Person_ID
• Accept_DtTm field or Arrive DtTm field
• Dispo DtTm field
• Dispo field
• Admit Type for APACHE II
• the Project Comfort Care from L_TmpV2 table, diagnosis code Palliative Service from L_DXs table, ICD10 code Z51.5 Palliative care from L_ICD10 table

Duplication?

Is this the same as Re-admission? Ttenbergen 12:03, 2017 July 5 (CDT) similar but specific with ICU. I will do a separate one for Med and delete the Re-admission after.
