About this study

The scope of this investigation is to demonstrate that the pUSIS values correlate closely with short term post-operative clinical outcome parameters, thus making this scoring system a good predictor for the patients' postoperative course and may become a helpful instrument for decision making concerning the choice of postoperative surveillance and treatment. The obtained follow up results were subjected to correlation analyzis with the pUSIS values in order to determine their association and if possible to recognize threshold values that may indicate a suitable type/intensity of postoperative surveillance.

Read the detailed description

a number of 60 day-care as well as 100 in-hospital patients undergoing elective surgery in general anesthesia have been enrolled into this observational study. The recruitment of cases happened randomly on a daily basis according to the available operations in the surgical unit where the main investigator (NN) was performing her/his anesthesiological services. Thus there was no selection of specific surgeries or surgical disciplines.

Inclusion criteria: adult patients (>18 y) undergoing surgery in general anesthesia.

Exclusion criteria: emergency cases, patients aged < 18 years, pregnant women, inability to give informed consent.

The data acquisition consisted of calculation of the individual pUSIS for the selected cases by end of surgery, and by collecting in the follow up period the following set of short term parameters:

In-hospital patients

  • time duration from end of surgery till discharge from PACU
  • time duration from end of surgery till discharge from IMCU
  • time duration from end of surgery till discharge from ICU
  • time duration from end of surgery till discharge from hospital up to 30 days
  • Occurrence and severity of complications the during hospital stay or up to 30 days according to a predefined list

Day-care patients

  • time duration from end of surgery till discharge from PACU
  • time duration from end of surgery till discharge from hospital
  • Occurrence and severity of complications the during hospital stay according to a predefined list
  • Occurrence of readmission due to complications within a period of 10 days after surgery

The predefined list of complications that could be observed during the follow up period consists of:

  • Occurrence of postoperative pain that needed medical intervention, duration of this state, average severity level (according an ordinal scale with the levels: mild, moderate, severe)
  • Occurrence of hemodynamic instability, duration of this state, average severity level (according an ordinal scale with the levels: mild, moderate, severe)
  • Occurrence of postoperative hemorrhage, quantification in total ml of estimated blood loss
  • Occurrence of respiratory support, duration of this state
  • Occurrence of thrombo-embolic complications
  • Occurrence of hepato-renal complications
  • Occurrence of cerebral/neurological complications
  • Occurrence of infectiological/inflamatory complications
  • Average level of self-assessed subjective wellbeing (according an ordinal scale with the levels: excellent, rather good, moderate, bad, extremely bad)

The obtained follow up results were subjected to correlation analyzis with the pUSIS values in order to determine their association and if possible to recognize threshold values that may indicate a suitable type/intensity of postoperative surveillance.

Questions about this trial

What is this clinical trial studying?

An observational study of Outcome Assessment, Health Care, run by University of Zurich at 1 site in Switzerland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 2 Apr 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Duration of postoperative hospital stay (time frame: 1-60 days). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04261231, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Apr 2020.
