Outcome Measures

Primary Outcomes (2)

  • CSA-AKI

    Cardiovascular surgery associated acute kidney injury. AKI was defined using the Kidney Disease: Improving Global Outcome (KDIGO) Clinical Practice Guideline for Acute Kidney Injury as an absolute increase in serum creatinine of ≥ 26 μmol/L within 48 hours or an increase in serum creatinine beyond 1.5 times the baseline value within 7 days

    7 days post operation

  • AKD

    Acute Kidney Disease, which was defined according to the criteria recommended by the Acute Disease Quality Initiative (ADQI) workgroup.4 AKI was quantified within the 7 days' postoperative period, while AKD was defined as serum creatinine value elevated to 1.5 times the baseline value between 8- and 90-day post-operation period.

    8 to 90 days post operation

Secondary Outcomes (6)

  • Incidence of AKD of stage 2 and above

    8 to 90 days post operation

  • RRT initiation

    from the end of operation to the discharge from hospital, up to 90 days.

  • value of eGFR

    7 days after operation

  • inpatient mortality

    30 days after inhospital

  • ICU length of stay

    from the end of operation to the discharge from ICU, up to 90 days.

  • +1 more secondary outcomes

Eligibility Criteria

Age18 Years - 90 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

All adults undergoing cardiac surgery between 2016 and 2020 (data analysed in 2021) using electronic health records collected from the Nanjing First Hospital.

You may qualify if:

  • Patients aged 18 years and older,
  • Patients underwent cardiac surgery (coronary artery bypass grafting, heart valve surgery, heart transplant or surgical excision of intracardiac myxoma)
  • Patients receiving invasive intraoperative BP monitoring during surgery
  • Patients underwent cardiopulmonary bypass (CPB) during surgery

You may not qualify if:

  • Pre-existing renal insufficiency defined by presence of abnormal preoperative serum creatinine ≥ 133 μmol/L and/or preoperative diagnosis of renal insufficiency within 6 months'preoperative period.
  • Patients with preoperative dialysis dependence within 60 days before the index surgical procedure,
  • Surgical duration less than 30 minutes
  • Surgery on the aorta
  • Insufficient hemodynamic and laboratory data for outcomes and/or exposure ascertainment
