About this study
The investigators thus propose to use an innovative randomized effectiveness trial design to test the theory that early automatic identification of a ¡ Low Systolic Blood Pressure¡± clinical condition and decision-support alerts will prompt earlier hemodynamic support and a consequently reduce the duration of such conditions. Specifically, the investigators will test the hypothesis that providing DSS alerts in regards to hypotension reduces the duration of hypotensive episodes. The core of the investigators study will be an existing electronic anesthesia record and smart-alarm decision-support system. All patients undergoing surgery at Hillcrest will be randomly assigned to routine care or to DSS support. In patients assigned to DSS support, a systolic blood pressure less than 80 mmHg will generate a warning within three minutes after detection. Clinicians will be free to act on the alert, ignore the alert, or to consider the provided information without acting on it. The randomization, complete anesthesia record, detailed record of hypotensive events, alerts provided, clinician responses, and SAP response, will be captured by the investigators electronic record-keeping system. The investigators primary outcome will be the duration of time the patient has a systolic blood pressure less than 80 mmHg. Secondary outcome will be duration of hospitalization. The investigators will assess the effect of the alert on the primary outcome of time to SBP returning to above 80 mmHg using survival analysis, with time to event censored (and considered a non-event) at either the end of surgery or end of monitoring if patient did not return to above 80 mmHg.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
low blood pressure alertOther
A Low Blood Pressure condition as specified (SAP <80 mmHg)will trigger an page to be sent to all anesthesia providers in <1 min that will read: "A Low Blood Pressure condition has been detected. Consider hemodynamic support."
standard of careOther
A Low Blood Pressure condition as specified (SAP <80 mmHg)will be monitored by treatment team upon detection, but additional paged alert will not be generated.

What is being measured
The primary outcome is the main question the study is designed to answer.
duration of time having low blood pressure
We plan to test the hypothesis that providing hypotension alerts reduces the duration of time patients spend in a low blood pressure condition.
Measured: day 1
Secondary outcomes (2)
hypotension
Secondary outcome will be the incidence of hypotension as well as duration of hospitalization
Measured: day 1
duration of hospitalization
Secondary outcome will be the incidence of hypotension as well as duration of hospitalization
Measured: up to day 3

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 0 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: withdrawn, as of the sponsor's last update on 25 Jan 2018. 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. Some participants in this study may receive a placebo. 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 was withdrawn before enrolling participants, so there are no results.
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 time having low blood pressure (time frame: day 1). 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 25 Jan 2018.
