Comparison of Post-Craniotomy Blood Pressure Targets (COMPETE)

April 15, 2026 updated by: Patrick Kelly, Vanderbilt University Medical Center

COMparison of Postcraniotomy Blood pressurE Target Effectiveness (COMPETE)

The goal of this pragmatic clinical trial is to learn if a more intensive or more liberal blood pressure target after surgery is more effective in improving patient outcomes for adults undergoing craniotomy for removal of a brain tumor. There is little evidence to help doctors decide the best post-operative blood pressure target for their patients. The main question this study aims to answer is if patients with a post-operative systolic blood pressure target of <160 mmHg will have a shorter hospital length of stay than those with a blood pressure target of <140 mmHg, without increasing the rate of post-operative bleeding in the brain.

Detailed Description

Over 160,000 craniotomies, a type of brain surgery, are performed annually in the United States. High blood pressure is believed to increase the risk of post-operative bleeding in the brain, known as intracranial hemorrhage (ICH). This perceived risk has led many doctors to impose post-operative systolic blood pressure (SBP) limits, with aggressive treatment when SBP rises above the target thresholds. The use of intensive SBP goals often requires antihypertensive medication treatment, occasionally including intravenous (IV) drips. These medical therapies could have several adverse effects related to end-organ function. Additionally, close SBP monitoring with an arterial line and/or treatment with IV antihypertensives often requires intensive care unit (ICU) level of care. 40% of academic medical programs use a goal of SBP<160mmHg as supported by this limited evidence, while 45% of programs use an even more stringent SBP goal of <140mmHg.

This study is a single-center, pragmatic, randomized trial comparing the effectiveness of these two standard-of-care post-craniotomy SBP goals in reducing patient hospital length of stay, risk of ICH, and adverse side effects of antihypertensive use. Eligible patients will be randomized to receive an order for a target SBP <140 mmHg or SBP <160 mmHg during this period. We hypothesize that a target SBP <160 mmHg will decrease patient hospital length of stay without increasing the risk of ICH.

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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Active Comparator: Comparator Arm 1: SBP target <160 mmHg
The neuro-intensive care team will monitor the patient's SBP and treat with antihypertensive medications to achieve an SBP<160mHg. Selection of the appropriate oral or IV medication is at the discretion of the neuro-ICU team; most frequently used agents clinically include nicardipine, labetalol, and hydralazine. Selection of the appropriate agent is based on other clinical elements including severity of hypertension, heart rate, patients' home medication regimens, and any medication interactions or allergies. The blood pressure goal will be continued throughout the hospitalization. The arterial line will be removed at the discretion of the neurosurgery team, typically on the morning of the first day after surgery.
Other: Target SBP <160mmHg
For subjects assigned to the SBP <160 mmHg group, an SBP target order will be placed to guide the neuro-intensive care team to treat the patient with antihypertensive medications as needed to achieve an SBP <160 mmHg. Selection of the antihypertensive medication and administration route is at the discretion of the treating team. Patients will undergo regular and frequent blood pressure measurements using the arterial line placed during surgery, or through a non-invasive blood pressure measurement method if no arterial line is present.
Active Comparator: Comparator Arm 2: SBP Target <140 mmHg
The neuro-intensive care team will monitor the patient's SBP and treat with antihypertensive medications to achieve an SBP<140mHg. Selection of the appropriate oral or IV medication is at the discretion of the neuro-ICU team, as described above for Comparator Arm 1. The blood pressure goal will be maintained until the neurosurgery team chooses to 'liberalize' the blood pressure goal to higher SBP levels. The arterial line will be removed when the blood pressure goal is liberalized, typically on the morning of the first day after surgery.
Other: Target SBP <140 mmHg
For subjects assigned to the SBP <140 mmHg group, an SBP target order will be placed to guide the neuro-intensive care team to treat the patient with antihypertensive medications as needed to achieve an SBP <140 mmHg. Selection of the antihypertensive medication and administration route is at the discretion of the treating team. Patients will undergo regular and frequent blood pressure measurements using the arterial line placed during surgery, or through a non-invasive blood pressure measurement method if no arterial line is present.
