Age-Standardized Rate for Hip Replacements

Description

This indicator measures the age-standardized hospitalization rate for hip replacement procedures performed in acute care hospitals or same-day surgery facilities per 100,000 population age 18 and older.

The indicator includes all hip replacement types: total hip replacement, monopolar/bipolar hemiarthroplasty and resurfacing procedures.

For further details, please see the General Methodology Notes (PDF).

Rationale

A hip replacement procedure has the potential to improve functional status, reduce pain and contribute to other gains in health-related quality of life. Over the past two decades, rates of hip replacement procedures have increased substantially. Wide inter-regional variation in joint replacement rates may be attributable to numerous factors, including the availability of services, provider practice patterns and patient preferences.

Description:

Total number of discharges or same-day visits for all hip replacement procedures for patients age 18 and older

Unit of analysis: Single admission or same-day visit

Inclusions:

  1. Hip replacement procedures occurring during inpatient stay or same-day visit CCI: 1.VA.53^^ and 1.SQ.53^^

    Note: Rates are based on the total number of discharges or same-day visits for hip replacement procedures in a given year. Therefore, a patient who received a bilateral hip replacement or underwent multiple hip replacement procedures within a single hospital admission or same-day visit would be counted only once.
  2. Age at admission: 18 and older
  3. Sex recorded as male or female
  4. Admission to an acute care institution or day surgery facility (Facility Type Code = 1 or A)

Exclusions:

  1. Records with cement spacers not coded as revision (intervention codes 1VA53LASLN and 1VA53LLSLN and Intervention Status Attribute does not equal R)
  2. Hip replacement procedures coded as out of hospital or abandoned after onset (OOH Indicator Flag = Y or Intervention Status Attribute = A)
  3. Newborn, stillbirth or cadaveric donor records (Admission Category Code = N, R or S)

Caveats and Limitations

Rates are based on the total number of discharges or same-day visits for hip replacement procedures in a given year. However, it is possible for a patient to undergo more than one hip replacement procedure in a single hospitalization or day surgery visit.

Trending Issues

As of 2013–2014, the hip replacement rate published in the Health Indicators e-Publication includes partial hip replacement procedures. Comparability with previous years will be affected.

Beginning with 2016–2017 data, the hip replacement rate published in the Health Indicators e-Publication and CJRR Quick Stats includes hip replacements performed in day surgery settings; comparability with previous years is not affected.

Comments

  1. Regional results are available in the Health Indicators e-Publication.
  2. Provincial results are also available in Quick Stats. Please note the following:
    • Prior to 2013–2014, results for Yukon, the Northwest Territories and Nunavut were suppressed in the CJRR annual report. However, their numbers are included in Canadian calculations.
    • Calculation of a patient's geography in the Health Indicators e-Publication is based on the Postal Code Conversion File (PCCF).
    • Beginning with 2015–2016 data, cement spacers are excluded from hip replacement cases when they are not revisions; comparability with previous years should not be affected.
    • As of 2016–2017, hip replacements performed in day surgery settings are included in the CJRR annual report.
