sql - 获取动态日期范围的计数

Question

我之前曾询问过有关此查询的信息，但我现在提出的问题与之前的问题完全不同。如果需要，请参阅此处了解上一个问题。

下面的代码应该为一个人计算一个数字，它应该使用以下信息：

获取停留时间并给每个范围一个分数，<-这有效

敏锐度评分，<-- 这行得通

共病评分，<-- 这行得通

ER 访问分数。<-- 这不起作用

我将以我自己为例：

假设我于 2013 年 6 月 18 日来到急诊室并入院。出院后，我将有一段时间的住院时间，这是根据 中的案例陈述评分的@T1，Acuity 也在那里计算。

在第二个查询中，我应该根据 2013 年 6 月 18 日的日期计算过去 6 个月内我来急诊室的次数。这是给我最大的悲痛点，也是我整个查询失败的点。对我来说棘手的是，每次有人进来时，他们都会得到一个访问 ID，但这个人只有一个 MRN 作为他们的唯一标识符。所以我必须根据每次就诊的出院日期计算过去 180 天内有人来过多少次。例如：

6-18-2013MCP来到急诊室并被录取

6-20-2013MCP出院

逗留时间 = 2

敏锐度 = 3

MCP2013 年 6 月 18 日（不计此）的 ER就诊次数 2013 年 1 月 1 日（计此）、2013 年 5 月 15 日（计此） 2013 年 2 月 19 日（计此） 2013 年 1 月 1 日（计）不计算这个）ER 访问 = 3 而不是 5

重要的是要注意对一个人的访问进行评分，而不是对个人本身进行评分，这是由于 ER 访问的日期范围限制。因此，我可以在 6 月 18 日的访问中获得分数，而在 7 月 30 日的访问中获得不同的分数。

到目前为止，我已经完整地给出了查询，以便可以评估我从头到尾的逻辑。我正在使用 SQL Server 2008。

此查询对@CM ON @T1表的遭遇号进行连接，并通过 MRN 对 ER 访问计数和 T1 表进行连接。由于一些非常奇怪的原因，当我像@CM on @T1MRN 那样进行最终连接时，我将获得单个 Encounter 编号的多条记录：

ENCOUNTER     |     MRN     |     CM SCORE
12345         |    99999    |        9
12345         |    99999    |       11

MRN 的 ER 就诊

请允许我通过创建抽象来简化您的查询。基本上，对于每个 MRN，您将能够获得一个结果集：MRN、Visit_ID、Visit_Date（我在<your sub query>下面称之为）

使用该列表，您可以运行以下查询来获取访问次数：

SELECT 
    A.MRN, 
    A.VISIT_ID, 
    A.VISIT_DATE, 
    COUNT(B.VISIT_ID) AS VISIT_COUNT FROM (<your sub query>) A
LEFT JOIN (<your sub query>) B ON 
    A.MRN = B.MRN AND 
    A.VISIT_DATE > B.VISIT_DATE AND A.VISIT_DATE - 180 < B.VISIT_DATE
GROUP BY A.MRN, A.VISIT_ID, A.VISIT_DATE

希望这可以帮助

编辑：<your sub query>应该是这样的：

SELECT MED_REC_NO AS MRN, VST_START_DTIME AS VISIT_DATE, PT_NO AS VISIT_ID 
FROM smsdss.BMH_PLM_PtAcct_V
WHERE
((
    PLM_PT_ACCT_TYPE = 'I'
    AND ADM_SOURCE NOT IN
        ('RA',
        'RP'
        )
    )
OR PT_TYPE = 'E')
