NCT01899443

Brief Summary

Primary total knee or total hip replacement surgeries are costly high volume procedures \& outcomes may be affected by surgical \& care processes \& individual patient characteristics. The primary hypotheses is that non compliance with recommended practice impacts patient outcomes (e.g. the likelihood of complications following surgery). The primary aims of the study are to evaluate the links between processes \& outcomes \& if possible develop a model that will improve patient outcomes \& reduce unnecessary practice variation whilst considering costs.

Outcome Measures

Primary Outcomes (1)

  • Percentage of participants experiencing the composite outcome up to 35 days post surgery.

    The proportion of patients in each group (compliant and non-compliant groups) that experience one or more of the following outcomes - death, readmission, reoperation or surgical complication - up to 35 days post-surgery. Analyses will adjust for patient and service provider confounders.

    35 days post total hip or knee replacement surgery

Secondary Outcomes (8)

  • Patient-reported quality of life

    35 days post surgery

  • Incidence of venous thromboembolism

    90 days post surgery

  • Incidence of deep infection.

    365 days post surgery

  • Costs of care processes

    90 days post surgery

  • Patient reported quality of life (QoL)

    90 days post surgery

  • +3 more secondary outcomes

Other Outcomes (1)

  • Day of first ambulation attempt post surgery

    day 0-14 post-surgery

Study Arms (1)

Total hip and knee replacement patients

This study will select up to 20 high volume (\>275 cases annually) public and private hospitals across Australia. A random sample of c.2200 patients with diagnosis of osteoarthritis undergoing primary total hip or knee replacement surgery will be recruited.

Other: Observation

Interventions

This is an observational study observing relationship between routine care and outcomes after total hip or knee arthroplasty.
