Analysis Check List
- Suppress numbers <5 or rates and proportions based on counts less than 5.
- For PHPDB: use Inpatient Discharges table from Hospital section of model, use Sum function on “Acute Care Length of Stay”, “ALC Length of Stay” or “Total Length of Stay” attribute.
- Select on geography of patient (geography could be postal code, postal code FSA, province, county-municipality, county, region, district health council or public health unit) using geography code not geography name. If geography code is not known, “Prompts” can be used or codes can be looked up in “Geo Names” Code Table. Institution geography can also be selected by linking to “Institution #” table.
- In hospital data, ICD-9 codes 800-999 refer to the Injury and Poisoning codes whereas these codes in the mortality data set refer to External Causes of Injury and Poisoning codes (e-codes). E-codes can be accessed by linking to the “External Causes” table but problems with double counting can be encountered.
Method of Calculation
annual # of hospitalization days for specific ICD chapter
| x 100,000 |
- Age groups: 0-9, 10-19, 20-44, 45-64, 65-74, 75+
- Sex: male, female
- Geographic areas of patient residence: health planning region, public health unit, district health council, county, municipality, forward sortation area (FSA) or postal code.
- ICD Chapter
- Acute Days, Alternative Level of Care (ALC) Days, Total Days
- The rate of days is strongly correlated with number of available hospital beds and is also affected by other factors not related to health status (availability of home care services, characteristics of physician/hospital, time of year, etc).
- Hospitalizations in psychiatric hospitals are excluded.
Alternative Level of Care (ALC) – An ALC patient is one who does not require acute care treatment, but is occupying an acute care bed while awaiting placement. The patient is classified as ALC when the physician gives an order to change the patient's status to "Medically Discharged".
