FIGURE Funnel plot of proportion of hip revision arthroplasties within one year after a total hip arthroplasty per hospital in the Netherlands in 2017-2021 (n=153,183)
Please note: The proportions of revisions within 1 year per hospital were adjusted for casemix factors age, gender, ASA score, BMI, smoking, charnley score and diagnosis (osteoarthritis versus other). THA: total hip arthroplasty; CL: control limits; CI: confidence interval. |
The mean 1-year revision percentage is 1.8 (95% CI: 1.8-1.9 ) in the Netherlands in 2017-2021.
Control limits indicate the plausible range of outcome if all hospitals perform equally well.

FIGURE Funnel plot of proportion of hip major revision arthroplasties within one year after a total hip arthroplasty per hospital in the Netherlands in 2017-2021 (n=153,183)
Please note: Major revision is defined as revision of at least acetabulum or femur compenent.
Please note: The proportions of revisions within 1 year per hospital were adjusted for casemix factors age, gender, ASA score, BMI, smoking, charnley score and diagnosis (osteoarthritis versus other).
THA: total hip arthroplasty; CL: control limits; CI: confidence interval.
The mean 1-year major revision percentage is 1.0 (95% CI: 1.0-1.1) in the Netherlands in 2017-2021.
Control limits indicate the plausible range of outcome if all hospitals perform equally well.
