Hospital volume has been suggested to be one of the best indicators of adverse orthopedic events in patients undergoing THR surgery. We therefore evaluated the effect of hospital volume on the length of stay, re-admissions, and complications of THR at the population level in Finland.
30,266 THRs performed for primary osteoarthritis were identified from the Hospital Discharge Register. Hospitals were classified into 4 groups according to the number of THRs performed on an annual basis over the whole study period: 1-50 (group 1), 51-150 (group 2), 151-300 (group 3), and > 300 (group 4).
In 2005, the length of the period of surgical treatment was 5.5 days in group 4 and 6.8 days in group 1 (the reference group). During the whole study period (1998-2005), the length of surgical treatment period was shorter in group 4 than in group 1 (p < 0.001). The odds ratio for dislocations (0.7, 95% CI: 0.6-0.9) was lower in group 3 than in group 1.
Hip replacements performed in high-volume hospitals reduce costs by shortening the length of stay, and they may reduce the dislocation rate.
医院手术量被认为是接受 THR 手术的患者发生不良骨科事件的最佳指标之一。因此，我们在芬兰人群水平上评估了医院手术量对 THR 住院时间、再入院和并发症的影响。
从住院患者登记簿中确定了 30266 例因原发性骨关节炎进行的 THR。根据整个研究期间每年进行的 THR 数量，将医院分为 4 组：1-50（组 1）、51-150（组 2）、151-300（组 3）和>300（组 4）。
2005 年，第 4 组的手术治疗期为 5.5 天，第 1 组（参考组）为 6.8 天。在整个研究期间（1998-2005 年），第 4 组的手术治疗期比第 1 组短（p<0.001）。与第 1 组相比，第 3 组脱位的比值比（0.7，95%CI：0.6-0.9）较低。
在高容量医院进行的髋关节置换术通过缩短住院时间来降低成本，并且可能降低脱位率。
