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.

Method/ Calculation

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).

Limitations

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.
