Trial summary

Aim of the study is to evaluate, whether the self administered quality of recovery (QoR-9) questionnaire can predict postoperative complications after non-cardiac surgery and whether preoperative risk estimates can be improved by implementation of the QoR-9 as postoperative screening tool.

About this study

Aim of the study is to evaluate, whether the self administered quality of recovery (QoR-9) questionnaire can predict postoperative complications after non-cardiac surgery and whether preoperative risk estimates can be improved by implementation of the QoR-9 as postoperative screening tool.

Read the detailed description

The QoR-9 as established patient-centred outcome measure, which is validated in German language, is surveyed preoperatively, as well as on postoperative day 1 and 3 after non-cardiac surgery. We showed in a pilot study that this score reveals a high sensitivity to detect patients with a disturbed health status through a detailed and time-consuming physical examination.We want to evaluate if short screening tools can be used to categorize patients with increased risk for developing postoperative complicationsTherefore, patients undergoing non-cardiac surgery are informed preoperatively about the study and written informed consent is obtained. Afterwards, the QoR-9, as well as validated preoperative risk scores are obtained. Relevant intra- and immediate postoperative factors are recorded. On postoperative day 1 and 3 patients perform the QoR-9. Postoperative complications during hospital stay are determined using the Clavien Dindo score by searching the patients 'record. After 6 months the patients are contacted via telephone and the QoR-9 is obtained. 6-months mortality is determined.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • QoR 9 QuestionnaireDiagnostic test

    The QoR-9 as established patient-centred outcome measure, which is validated in German language, is surveyed preoperatively, as well as on postoperative day 1 and 3 after non-cardiac surgery. Postoperative complications are evaluated using the Clavien-Dindo Score. A follow-up is intended after 6 months. Preoperative risk is estimated using the ASA (American Society of Anesthesiologists) and the POSPOM (Preoperative Score to predict postoperative mortality) score.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Postoperative Complications evaluated by Clavien- Dindo Score

    Nine domains are evaluated: Pulmonary, infectious, renal, gastrointestinal, cardiovascular, neurological, wound, haematological and pain. Each domain is graded between grade I and V (death of a patient).

    Measured: Date of Surgery till Discharge from Hospital (approximately 30 days)

Secondary outcomes (3)
  1. hospital mortality

    Rate of Mortality among study patients

    Measured: Date of Surgery till Discharge from Hospital (approximately 30 days)

  2. 6-month mortality

    Mortality among patients 6 months after surgery

    Measured: 6 month after date of surgery

  3. Superiority of QoR-9 questionnaire against common Outcome Score

    Comparison of different risk estimates and Outcome Scores

    Measured: Date of surgery until 6 month follow-up

The record says: finished, as of the sponsor's last update on 25 Aug 2021. 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 Germany. 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?

Postoperative Complications evaluated by Clavien- Dindo Score (time frame: Date of Surgery till Discharge from Hospital (approximately 30 days)). 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 NCT03669419, which also lists 6 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?
