We investigate the issue of patient readmission at a large academic hospital in the U.S. Specifically, we look for evidence that patients discharged when post-operative unit utilization is high are more likely to be readmitted. After examining data from 7,800 surgeries performed in 2007, we conclude that patients who are discharged from a highly utilized post-operative unit are more likely to be readmitted within 72 h. Each additional bed utilized at time of discharge increases the odds of readmission on average by 0.35% (Odds Ratio = 1.008, 95% CI [1.003, 1.012]). We propose that this effect is due to an increased discharge rate when the unit is highly utilized.
我们研究了美国一家大型学术医院的患者再入院问题。具体来说，我们寻找证据表明，在术后单位利用率高时出院的患者更有可能再次入院。在检查了 2007 年进行的 7800 例手术的数据后，我们得出结论，从高利用率的术后单位出院的患者在 72 小时内再次入院的可能性更大。出院时每增加一个使用的床位，平均再入院的几率增加 0.35%（优势比=1.008，95%置信区间[1.003，1.012]）。我们提出，这种影响是由于单位利用率高时出院率增加所致。
