Description

This measure is used to assess the age-standardized rate of new hip fractures admitted to an acute care hospital per 100,000 population age 65 and older.

A new event is defined as a first-ever hospitalization for hip fracture or a subsequent hip fracture occurring more than 28 days after the admission for the previous event in the reference period.

Calculation Description: (Total number of new hip fracture events for persons age 65 and older ÷ Total mid-year population age 65 and older) × 100,000 (age-adjusted)

Rationale

Hip fractures represent a significant health burden for seniors and the health system. As well as causing disability or death, hip fracture may have a major effect on independence and quality of life. Measuring occurrence of hip fractures in the population is important for planning and evaluating preventive strategies, allocating health resources and estimating costs.

Numerator Inclusions/Exclusions

Inclusions
Total number of new hip fracture events* for persons age 65 and older

  1. Hip fracture present on admission coded as diagnosis type (1) or type (M), (W), (X) or (Y) but not also as a diagnosis type (2)
  2. Age at admission: 65 and older
  3. Sex recorded as male or female
  4. Admission to an acute care institution
  5. Canadian resident

Note: Refer to the original measure documentation for the administrative codes.

*A new event is defined as a first-ever hospitalization for hip fracture or a subsequent hip fracture occurring more than 28 days after the admission for the previous event in the reference period.

Exclusions

  1. Records with an invalid health card number
  2. Records with an invalid date of birth (non-Quebec records)
  3. Records with an invalid admission date
  4. Cadaveric donor or stillbirth records (Admission Category = R or S)
  5. Hip fracture admissions within 28 days after the admission date of the previous hip fracture hospitalization
  6. Transfers**

**If a subsequent hip fracture admission occurs on the same day as or prior to the discharge date of a previous hip fracture admission, it is considered a transfer.

Allowance for Patient or Population Factors

Analysis by subgroup (stratification by individual factors, geographic factors, etc.)

Description of Allowance for Patient or Population Factors

  • Indicators are reported at the national, provincial/territorial, and regional levels.
  • Unless otherwise specified, for indicators based on place of residence, data is reported based on the region of the patient's residence, not region of hospitalization. Consequently, these figures reflect the hospitalization experience of residents of the region wherever they are treated, including out of province, as opposed to the comprehensive activity of the region's hospitals (that will also treat people from outside of the region). Hospitalizations occurring in the U.S. or abroad are not included.
  • For indicators based on place of service (where the patient was treated), data is reported based on the administrative region of the facility (e.g., region of hospitalization).
  • Rates are standardized or risk-adjusted wherever possible to facilitate comparability across provinces/regions/facilities and over time.
  • Standardized rates are adjusted by age (collapsed to five-year groupings) using a direct method of standardization based on the July 1, 1991, Canadian population.
