* 住院发退药业务中,发药明细(DispensingDetail)与发药汇总单(DispensingSummary)的
|
||||
* 数据写入时机不一致,导致两者状态不匹配,存在业务脱节风险。
|

* 关键修复点(Bug #505):
|

* 在“医嘱校对”模块,护士仍能对已发药的医嘱执行退回操作。已在退回业务中加入
|
||||
* 发药状态校验,防止已发药医嘱被错误退回。
|

* 关键修复点(Bug #575):
|

* 门诊预约挂号成功后,未实时累加 {@link SchedulePool#bookedNum},导致
|

* 可预约人数统计不准确。新增对 {@code SchedulePool} 的乐观锁更新,
|

* 确保在同一时间段的并发预约能够正确累计。
