The objective of this study was to determine whether replacing the "routine" postoperative visit after surgical abortion with an "as indicated" visit is associated with an increase in the rates of either failed abortion (continuing pregnancy) or repeat abortion.
We compared the rate of continuing pregnancy in 50,702 first-trimester surgical abortion patients who were offered routine postoperative visits in one time period (1/1/00-4/30/07) to the rate in 20,315 first-trimester surgical abortion patients from a later time period (5/1/07-12/31/09) in which routine postoperative visits had been discontinued. We also compared the rate of repeat abortion within 1 year of the initial procedure for both first- and second-trimester surgical abortion patients for the same time periods.
The rate of continuing pregnancy remained stable before and after routine visits were discontinued (39.4 per 100,000 first-trimester surgical abortions for each group).The rate of repeat abortion within 1 year after the initial procedure was lower after routine visits were discontinued (8.2%) than before routine visits were discontinued (8.7%), p=.007.
We conclude that elimination of the routine postoperative visit after a surgical abortion and the substitution of an "as indicated" postoperative visit are not associated with an increase in either continuing pregnancies or repeat abortion.
本研究旨在确定在手术后常规随访后改为“按需”随访是否会增加流产失败（持续妊娠）或重复流产的发生率。
我们比较了在一个时间段内（2000 年 1 月 1 日至 2007 年 4 月 30 日）接受常规术后随访的 50702 例早期人工流产患者的继续妊娠率，与另一个时间段（2007 年 5 月 1 日至 2009 年 12 月 31 日）接受常规术后随访的 20315 例早期人工流产患者的继续妊娠率。我们还比较了同一时期初诊后 1 年内重复行人工流产术的患者的重复流产率。
在停止常规随访前后，继续妊娠率保持稳定（两组中每 10 万例早期人工流产的继续妊娠率分别为 39.4 例）。在停止常规随访后，初诊后 1 年内重复行人工流产术的比率（8.2%）低于停止常规随访前（8.7%），p=.007。
我们的结论是，在人工流产手术后取消常规随访并代之以“按需”随访并不会增加持续妊娠或重复流产的发生率。
