30-Day Readmission: Patients Age 19 and Younger


<div role="button" class="expandableTitle" aria-controls="descAndCalRegion">Indicator Description and Calculation</div>
Description

This indicator measures the risk-adjusted rate of urgent readmission for patients age 19 and younger.

For further details, please see the General Methodology Notes.

Calculation: Description

Risk-adjusted rate = Observed number of readmissions ÷ Expected number of readmissions × Canadian average readmission rate

Unit of analysis: Episode of care

An episode of care refers to all contiguous inpatient hospitalizations and same-day surgery visits. For episodes with transfers within or between facilities, transactions were linked regardless of diagnoses. To construct an episode of care, a transfer is assumed to have occurred if either of the following conditions is met:

a) An acute care hospitalization or a same-day surgery visit occurs less than seven hours after discharge from the previous acute care hospitalization or same-day surgery visit, regardless of whether the transfer is coded;

b) An acute care hospitalization or same-day surgery visit occurs between 7 and 12 hours after discharge from the previous acute care hospitalization or same-day surgery visit, and at least one of the hospitalizations or visits has coded the transfer.

Notes

–For public reporting: Regional and provincial/territorial results are calculated by place of residence; facility results are calculated by place of service.

–For facility-level reporting: For episodes of care that involved transfers, readmissions were attributed to the last hospital from which the patient was discharged before readmission.

Denominator

Description:
Number of episodes of care for patients age 19 and younger discharged between April 1 and March 1 of the fiscal year
Inclusions:
1. Episodes involving inpatient care (Facility Type Code = 1). An episode may start or end in a day surgery setting. Episodes that both start and end in day surgery settings are not included.

2. Age younger than 20 years at admission

3. Discharge between April 1 and March 1 of the following year (period of case selection ends on March 1 of the following year to allow for 30 days of follow-up)

4. Sex recorded as male or female
Exclusions:
1. Records with an invalid health card number

2. Records with an invalid code for province issuing health card number

3. Records with an invalid admission date or time

4. Records with an invalid discharge date or time

5. Episodes with admission category of newborn (Admission Category Code = N)

6. Records with admission category of cadaveric donor or stillbirth (Admission Category Code = R or S)

7. Episodes with discharge as death, self sign-out or patient not returning from a pass (Discharge Disposition Code = 06, 07 or 12)

8. Presence of at least one record in the episode with major clinical category (MCC) of Mental Diseases and Disorders (MCC = 17)

9. Presence of at least one record in the episode with MCC of Pregnancy and Childbirth (MCC = 13)

10. Presence of at least one record in the episode with palliative care (ICD-10-CA: Z51.5) coded as most responsible diagnosis (MRDx). For Quebec data: Z51.5 coded as MRDx, or cancer (C00–C97) coded as MRDx and Z51.5 coded in any secondary diagnosis field.

For an illustration of denominator selection, please refer to the flowchart in the General Methodology Notes document.

Numerator

Description:
Cases within the denominator with a non-elective readmission within 30 days of discharge after the index episode of care
Inclusions:
1. Emergent or urgent (non-elective) readmission to an acute care hospital (Admission Category Code = U and Facility Type Code = 1)

2. (Admission date on readmission record) − (Discharge date on the last record of the index episode of care) less than or equal to 30 days
Exclusions:
Presence of at least one record in the episode with one of the following:

1. Delivery (ICD-10-CA: O10–O16, O21–O29, O30–O37, O40–O46, O48, O60–O69, O70–O75, O85–O89, O90–O92, O95, O98, O99 with a sixth digit of 1 or 2; or Z37 recorded in any diagnosis field)

2. Chemotherapy for neoplasm (ICD-10-CA: Z51.1) as MRDx

3. Admission for mental illness (MCC = 17)

4. Admission for palliative care (ICD-10-CA: Z51.5) coded as MRDx; for Quebec data: Z51.5 coded as MRDx, or cancer (C00–C97) coded as MRDx and Z51.5 coded in any secondary diagnosis field

5. Records with an invalid admission date


<div role="button" class="expandableTitle" aria-controls="backgroundRegion">Background, Interpretation and Benchmarks</div>
Rationale

Urgent readmissions to acute care facilities are increasingly being used to measure institutional or regional quality of care and care coordination.

Readmission rates can be influenced by a variety of factors, including the quality of inpatient and outpatient care, effectiveness of the care transition and coordination, and the availability and use of effective community-based disease management programs. While not all urgent readmissions are avoidable, interventions during and after a hospitalization can be effective in reducing readmission rates.

Interpretation

Lower rates are desirable.
