This SQL query is a complex extraction of data related to ICU stays for patients who have been diagnosed with various forms of atrial fibrillation and atrial flutter. Here's a breakdown of the logic and what each part of the code does:

1. Basic CTE (Common Table Expression) – basic:

  • This CTE identifies the cohort of patients who have been diagnosed with any form of atrial fibrillation or atrial flutter from the mimiciv_hosp.diagnoses_icd table.
  • It includes diagnoses like:
    • Atrial fibrillation (ICD codes: '42731')
    • Atrial flutter (ICD codes: '42732')
    • Paroxysmal atrial fibrillation (ICD code: 'I480')
    • Persistent atrial fibrillation (ICD code: 'I481')
    • And other forms, including unspecified types and typical atrial flutter.

This section ensures that only patients with the relevant diagnoses (identified by the ICD codes) are selected.

  • It then uses the mimiciv_derived.icustay_detail table to fetch ICU stay data for these patients, including admission time, discharge time, ICU admission and discharge times, and the first and last care units they stayed in.

2. YuHou_Final CTE:

  • This section builds upon the data in the basic CTE and combines it with the admissions table (mimiciv_hosp.admissions) to extract data about patient outcomes, particularly death information.
  • The following columns are calculated or derived:
    • Admission time (admittime) and discharge time (dischtime).
    • ICU death time (icu_dod) and hospital death time (deathtime).
    • Flags are set based on whether a patient is dead:
      • is_dead: 1 if the patient died, NULL otherwise.
      • is_hosp_dead: 1 if the patient died during their hospital stay (but not necessarily in the ICU).
      • is_icu_dead: 1 if the patient died during their ICU stay.

This CTE provides an overall view of patient survival after ICU admission, including details on whether the death occurred within the ICU or hospital and the timing.

3. YuHou CTE:

  • This section combines the data from the basic CTE, the YuHou_Final CTE, and the admissions table (mimiciv_hosp.admissions).
  • Additional calculations for survival times are made, including:
    • hospital survival time: The time from ICU admission to hospital death (if any).
    • ICU survival time: The time from ICU admission to ICU death (if any).
  • Flags for death within 28 days of hospital stay and death within 28 days of ICU stay are also calculated, based on the deathtime and icu_intime.

This CTE is used to identify key survival metrics for patients, looking at whether they survived or died during their ICU or hospital stay, and the length of time they survived after their ICU admission.

4. Final Output:

  • The query returns all the relevant data for each patient (subject_id), including:
    • Admission and discharge times, both in the hospital and ICU.
    • Death-related information (e.g., if the patient died in the hospital or ICU, and if they survived beyond 28 days in the hospital/ICU).
    • Survival times (how long the patient survived during their hospital and ICU stay).
    • Flags indicating death and survival status.

Summary of the Query's Purpose:

The query is designed to generate a detailed report of ICU patients who were diagnosed with atrial fibrillation or atrial flutter, capturing their ICU admission/discharge details, survival status, and death-related information (whether they died in ICU, in the hospital, or survived). The query also calculates the time spent in the hospital and ICU, along with specific survival metrics like whether the patient survived beyond 28 days in either setting.

This can be particularly useful for analyzing the outcomes of patients with specific heart conditions (e.g., atrial fibrillation) in ICU settings, allowing for further research into patient survival and hospital/ICU stays.

”有什么区别？麻烦用中文回答

Risposta

这两个 SQL 查询的结构和逻辑几乎是相同的，区别主要体现在以下几个方面：

1. 诊断的范围

  • 第一个查询：仅包含了与 房颤（Atrial fibrillation） 和 房扑（Atrial flutter） 相关的 ICD 诊断代码（ICD 代码为 42731、42732、I480、I481 等）。其中，还明确列出了多种类型的房颤和房扑的诊断。
  • 第二个查询：与第一个查询类似，但有一个不同之处，即它还添加了 Atrial fibrillation and flutter（ICD 代码为 I48）和 Unspecified atrial fibrillation and atrial flutter（ICD 代码为 I489）等更广泛的诊断。因此，第二个查询涵盖了更广泛的房颤和房扑相关的诊断。

2. 排除的诊断

  • 第一个查询：对排除的诊断进行了一定筛选，排除了那些患有 恶性肿瘤（CA） 的患者（ICD 代码为：1629、185、1970、1976 等）。
  • 第二个查询：没有类似的排除条件，因此它没有排除任何与恶性肿瘤相关的患者诊断。

3. 查询的范围

  • 第一个查询：在查询 basic CTE 的基础上，明确限制了与房颤和房扑相关的诊断和排除了恶性肿瘤的患者。
  • 第二个查询：查询的逻辑与第一个查询几乎相同，但它没有排除恶性肿瘤患者，意味着查询结果可能包含有恶性肿瘤的患者。

4. 结果集的含义

  • 第一个查询：通过筛选房颤、房扑等相关疾病并排除恶性肿瘤患者，目的是对特定患者群体进行分析，评估这些患者在 ICU 中的治疗情况以及死亡率等。
  • 第二个查询：通过包含更广泛的房颤和房扑类型以及不排除恶性肿瘤的患者，分析的患者范围更广，可能会导致更广泛的结论，但也可能包含一些恶性肿瘤患者的影响。

总结：

  • 第一个查询 更加专注于排除恶性肿瘤的患者，确保仅分析房颤和房扑患者的 ICU 治疗和结果。
  • 第二个查询 在分析房颤和房扑患者时，包含了更广泛的诊断类型，并没有排除恶性肿瘤的患者，因此结果集可能会更广泛。
