About this study
Official title: Finding Good TEMporal PostOperative Pain Signatures (TEMPOS)
The purpose of this research study is to determine what causes pain after surgery to increase or decrease over time.
Read the detailed description
Before surgery, study participants will be asked questions about age, gender, race/ethnicity, annual income, and education level. Study participants will also be questioned regarding prior pain experiences, their mood and how they think about pain. A small test tube of blood, a cheek swab or a saliva sample will be taken to see what genetic differences may influence individuals pain after surgery.
After surgery, study participants will be asked questions about their pain intensity while in the hospital. Additional information will be collected about the effects of pain medicine, and their recovery from surgery.
Following discharge from the hospital, study participants will be contacted monthly to confirm continued communication. Study participants will also be contacted six months after surgery, and asked to complete a final survey about their pain after surgery.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Surgical patients' clinical progressionBehavioural
Study the dynamic nature of pain
Genetic markersGenetic
Research variants in genes related to pain sensitivity, analgesic sensitivity and opioid response
| Study group | Role | What they receive |
|---|---|---|
| Surgical patients' clinical progression | Patients undergoing non-ambulatory surgery will be asked questions and complete surveys in an effort to characterize postoperative pain experience profiles. A blood sample will be obtained for genetic markers exploring a variety of pain-related genes. Receives: Behavioral: Surgical patients' clinical progression; Genetic: Genetic markers |
What is being measured
The primary outcome is the main question the study is designed to answer.
Measure postoperative pain scores change with respect to time
Pain scores will be measured using previously established pain scale and Questionnaire
Measured: up to 7 days
Secondary outcomes (3)
Measure variables that contribute to postoperative pain scores
Variables: clinical, biological, psychological, and social factors
Measured: up to 6 months
Measure timing patterns that may influence development of persistent postsurgical pain (PPP)
Different patterns of pain analgesia-pain cycles
Measured: up to 6 months
Genetic testing
Specific single nucleotide polymorphisms
Measured: up to 1 day

Questions about this trial
What is this clinical trial studying?
An observational study of Pain, Postoperative, run by University of Florida at 1 site in United States.
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 3 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 19 Jan 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 United States. 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?
Measure postoperative pain scores change with respect to time (time frame: up to 7 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 19 Jan 2021; AzTrials last refreshed its copy on 30 Oct 2026.
