POSSUM, P-POSSUM, Clinical Frailty Scale, Clinical Frailty Scale and Charlson's Comorbidity Index in Abdominal Surgery.

Abdominal surgery represents the most frequent activity in the surgical block. Advances in surgical techniques and improvements in postoperative care imply the need for greater control of the surgical outcomes obtained and the comparison of results between services with the same characteristics with the help of assessment scales.

A prospective observational study will be carried out during 2021. All patients undergoing abdominal surgery will be included. Demographic variables, personal and surgical history, preoperative and intraoperative data, and variables related to surgery will be collected. At 30 days postoperatively, the clinical history of the patients will be reviewed and postoperative complications will be collected as well as the mortality that occurred. With these data, the POSSUM, the P-POSSUM, the Clinical Frailty Scale and the Charlson comorbidity index will be calculated.

About this study

Abdominal surgery represents the most frequent activity in the surgical block. Advances in surgical techniques and improvements in postoperative care imply the need for greater control of the surgical outcomes obtained and the comparison of results between services with the same characteristics with the help of assessment scales.

A prospective observational study will be carried out during 2021. All patients undergoing abdominal surgery will be included. Demographic variables, personal and surgical history, preoperative and intraoperative data, and variables related to surgery will be collected. At 30 days postoperatively, the clinical history of the patients will be reviewed and postoperative complications will be collected as well as the mortality that occurred. With these data, the POSSUM, the P-POSSUM and the Charlson comorbidity index will be calculated.

Once this data are collected, the following objectives will be met:

  • Validate the POSSUM and P-POSSUM systems in patients undergoing gastrointestinal surgery in our hospital, comparing the estimated morbidity and mortality with that observed 30 days after surgery.
  • Analyze the correlation of estimated morbidity and mortality of the POSSUM and P-POSSUM with respect to that observed in scheduled surgery vs. emergencies.
  • Analyze the correlation of estimated morbidity and mortality of POSSUM and P-POSSUM with respect to that observed in laparoscopic surgery vs. laparotomy
  • Establish the relationship and predictive ability of Clinical Frailty Scale and Charlson Comorbidity Index with respect to morbidity and mortality at 30

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • All patients undergoing scheduled or urgent intervention for gastrointestinal surgery will be included in the study.

Exclusion criteria

  • Patients operated under locoregional anesthesia.
  • Patients undergoing Major Ambulatory Surgery (CMA) regardless of postoperative destination (home or hospitalization floor).
  • Patients intervened on a scheduled basis in the afternoon shift
  • Patients who require surgery after the first 24 hours of hospital admission

Treatment and study plan

POSSUM

Diagnostic Test

These scales will be calculated and compared to the outcomes obtained in our center.

Other names: P-POSSUM, Charlson comorbidity index, Clinical frailty scale

Primary outcomes

  1. Validate the POSSUM and P-POSSUM systems in patients undergoing gastrointestinal surgery

    Time frame: 30 days after surgery.

    To compare the estimated morbidity and mortality with that observed.

Secondary outcomes

  1. Analyze the correlation of estimated morbidity and mortality of the POSSUM and P-POSSUM with respect to that observed in scheduled surgery vs. emergencies.

    Time frame: 30 days after surgery.

    To compare the estimated morbidity and mortality with that observed.

  2. Analyze the correlation of estimated morbidity and mortality of POSSUM and P-POSSUM with respect to that observed in laparoscopic surgery vs. laparotomy

    Time frame: 30 days after surgery.

    To compare the estimated morbidity and mortality with that observed
