Brief Summary

This study aims to identify the risk factors associated with postoperative pulmonary complications (PPCs) in patients aged 65 years and older who undergo major abdominal surgery. The study is designed as a retrospective observational analysis using data from patient records. Understanding these risk factors may help clinicians improve perioperative care and reduce the risk of respiratory problems after surgery in elderly patients.

Conditions

Pneumonia; Postoperative Complications

Outcome Measures

Primary Outcomes (1)

• Incidence of Postoperative Pulmonary Complications

  The primary outcome is the occurrence of one or more postoperative pulmonary complications (PPCs) in patients aged 65 years and older undergoing major abdominal surgery. PPCs include pneumonia, respiratory failure, or need for reintubation, as defined by the European Perioperative Clinical Outcome (EPCO) criteria. Data were collected retrospectively from patient records during the postoperative hospital stay.

  Within 1 day after surgery

Study Arms (2)

Group 1: Patients with postoperative pulmonary complications (PPC +)

Group 1 - Patients with postoperative pulmonary complications (PPC +): This group includes patients aged 65 years and older who underwent major abdominal surgery and developed one or more postoperative pulmonary complications, as defined by EPCO criteria

Group 2: Patients without postoperative pulmonary complications (PPC -)

Group 2 - Patients without postoperative pulmonary complications (PPC -): This group includes patients aged 65 years and older who underwent major abdominal surgery but did not develop any postoperative pulmonary complications.

Eligibility Criteria

• Age: 65 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

The study population consists of patients aged 65 years and older who underwent major abdominal surgery. Only patients with complete perioperative and postoperative medical records were included. Patients were retrospectively classified into two groups based on the occurrence of postoperative pulmonary complications (PPCs) within the first 24 hours after surgery.

You may qualify if:

• Patients aged 65 years or older.
• Patients who underwent major abdominal surgery at \[Institution Name\].
• Availability of complete perioperative and postoperative clinical records.
• Postoperative hospital stay of at least 24 hours.

You may not qualify if:

• Patients younger than 65 years.
• Patients undergoing minor or non-abdominal surgery.
• Incomplete or missing perioperative or postoperative medical records.
• Patients who underwent emergency surgery
