Connecticut Joint Replacement Institute
Question/ Intervention Goal/Objectives
Connecticut Joint Replacement Institute puts patient data at the
physician’s fingertips, so that treatment is more responsive and outcomes
more successful. Clinical decision-making is guided at each step by
comprehensive relevant and actionable data. CJRI’s hip and knee
arthroplasty patients have fewer post-discharge emergency department
visits and hospital readmissions 30 days after their surgery. ED and
hospital readmissions are both recognized as quality indicators for this
type of surgery.
Using several data sources, CJRI calculated the percent of hip arthroplasty
and knee arthroplasty patients who has an emergency department
(without a hospital readmission) within 30 days of surgery; and the percent
who has a hospital readmission within 30 days of surgery. All 3,198 patients
who underwent primary total hip and knee arthroplasty in 2019 were
included in the analysis.
These rates were compared to a benchmark from published literature.
Findings/ Metric/ Outcome/ Savings
Among 3,198 CJRI patients for primary hip and knee arthroplasty during
2019, 2.72% had an emergency department visit within 30 days of surgery
but were not readmitted to the hospital. This compares to 3.6% (for total
hip arthroplasty), and 5.3% (for combined total hip and knee arthroplasty).
In 2019, 1.45% of CJRI hip and knee arthroplasty patients were readmitted
to the hospital within 30 days of their surgery. This compares to 4.2% (knee
replacement) and 5.6% (hip replacement).
The CJRI patients may differ from the patient groups in the cited literature;
however, the large number of patients and the period of time analyzed
indicate a high consistency in CJRI’s performance.
