About this study

At present, there is conflicting evidence regarding outcomes in patients with septic shock receiving weight-based vasopressor (WBVP) versus non-weight-based vasopressor (NWBVP) dosing strategies. At MCMC, a weight-based strategy is in place whereas MDMC, MMMC and MRMC currently utilize a non-weight-based dosing strategy. Obese patients (BMI > 30) receiving either strategy may potentially be receiving substantially more or less vasopressor exposure compared to their non-obese (BMI < 30) counterparts. Determining total vasopressor exposure and assessing clinical outcomes would benefit our institution and others by providing optimal vasopressor dosing strategies in obese and non-obese patients. There is a difference in clinical outcomes between patients receiving weight-based and non-weight-based vasopressor dosing strategies. There is a difference in total vasopressor exposure between obese and non-obese patients utilizing WBVP and NWBVP strategies.

Read the detailed description

Vasopressors are a mainstay of therapy for patients with septic shock to achieve and maintain hemodynamic stability.1 Both weight-based and non-weight-based dosing recommendations exist with no clear evidence that one is better than the other.3-10 However, in light of the obesity epidemic and emerging evidence regarding the dangers of excessive catecholamine exposure, an evaluation of dosing practices is warranted. The aim of this study is to determine whether clinical outcomes differ between patients receiving weight-based and non-weight-based vasopressor dosing strategies for septic shock. This is a multicenter, retrospective chart review. Patients admitted to MDMC and MCMC from 4/1/2017-8/31/2019 will be identified through the electronic medical record utilizing ICD codes for sepsis and septic shock. Patients meeting study inclusion criteria will be analyzed as described below. Outcomes will be assessed between patients receiving WBVP and NWBVP with planned subgroup analysis in each group between patients with BMI < 30, 30-49, and > 50.

What is being measured

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

  1. Efficacy: Total 48-hour vasopressor exposure

    Total 48-hour vasopressor exposure (norepinephrine (NE) equivalents, mg)

    Measured: 4/1/2017-8/31/2019

  2. Safety: Composite of in-hospital mortality, vasopressor-associated adverse events

    Composite of in-hospital mortality, vasopressor-associated adverse events (arrhythmia, thrombosis)

    Measured: 4/1/2017-8/31/2019

Secondary outcomes (2)
  1. Efficacy: Total number of vasoactive agents required to maintain mean arterial pressure

    Total number of vasoactive agents required to maintain mean arterial pressure (MAP) > 65 mmHg, time to hemodynamic stability, use of angiotensin II or vasopressin

    Measured: 4/1/2017-8/31/2019

  2. Safety: in-hospital mortality, vasopressor-associated adverse events

    in-hospital mortality, vasopressor-associated adverse events (arrhythmia, thrombosis)

    Measured: 4/1/2017-8/31/2019

Questions about this trial

What is this clinical trial studying?

An observational study of Septic Shock and Weight, Body, run by Methodist Health System 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 5 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 27 Mar 2026. 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?

Efficacy: Total 48-hour vasopressor exposure (time frame: 4/1/2017-8/31/2019). The study lists 2 primary outcomes in all. 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 27 Mar 2026.
