Prospective Data Analysis of a Quality Improvement Initiative in High Risk Cardiac Surgery Patients

August 27, 2020 updated by: Davinder Ramsingh, MD, Loma Linda University

Prospective Data Analysis of a Quality Improvement Initiative for Perioperative Hemodynamic Optimization Therapy and Postoperative Outcomes in Patients Undergoing High-Risk Cardiac Surgery

This project is designed to assess the impact of implementing a hemodynamic optimization protocol, utilizing flow guided parameters that is provided by technology from Edwards Lifesciences, for patients undergoing high risk cardiac surgery. Importantly, this project is being targeted as a QI initiative because there is no evaluation of new technology or procedures. All technologies and procedures are currently being used for patients undergoing cardiac surgery. Rather this project is evaluating the implementation of a multi-dispclinary developed protocol that seeks to remove variability in which providers are currently treating patients hemodynamics during and acutely after cardiac surgery. Previous research has demonstrated that implementation of hemodynamic management protocols improves perioperative outcome in surgical patients. This project seeks to evaluate the impact of implementing this protocol as the new clinical standard for high-risk cardiac surgery patients. Specifically, this protocol would be a comprehensive hemodynamic management strategy that would-be initiated in the operating room post-bypass and then continued for the first 12 hours in the intensive care unit (see figure below). To restate, all technologies and procedures are currently being performed for these patients, however, there has not been a protocol guiding how practionioners use this technology. The project is evaluating the impact of protocolized treatment strategies. Importantly this protocol has been designed, reviewed and agreed by the motivation of the physicians who are currently responsible for managing these patients hemodynamics. Since this project does involve alterations in procedures or technologies we are seeking to proceed as a quality improvement project. Additionally the protocol is one that has been reviewed and agreed to provide the optimal management strategy for these patients. This again is the overall focus of this project, to implement a hemodynamic management protocol to improve outcomes in patients undergoing cardiac surgery.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Observational

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

All adult high risk cardiac surgical patients undergoing procedures requiring cardiopulmonary bypass. High risk was defined, a priori, as patients who are expected to require an inotropic and/or vasoconstrictive agent for more than 12 hours post-CPB.

Description

Inclusion Criteria:

(1) the procedure was a first-start case, (2) the procedure was scheduled, (3) the procedure is considered non-emergent, and (4) the cardiac surgery required cardiopulmonary bypass

Exclusion Criteria:

(1) Patients less than 18 years of age, (2) failure to undergo CPB, (3) non-first-start or emergent classification, (4) as well those who did not receive at least 12 hours of inotropic and/or vasoconstrictive agents were excluded from the study.

Design Details

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Length of Stay
Time Frame: days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Major postoperative complications identified as:
Time Frame: during hospitalization
1) incidence of stroke, (2) incidence of renal failure (defined as a threefold or greater rise in creatinine or new dialysis requirement), (3) prolonged intubation (>24 hours), and/or (4) a sternal wound infection.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 17, 2019

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
February 1, 2020

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
