Impact of Pre-anesthetic Evaluation on the Anxiety (iPAEonAnx)

June 19, 2025 updated by: Fabricio Tavares Mendonca, Hospital de Base

The Impact of Pre-anesthetic Evaluation on the Anxiety of Orthopedic Patients: a Randomized Clinical Trial.

Since the last century, it has been understood that "the pre-anesthetic evaluation is the patient's right and the anesthesiologist's duty." As early as 2006, the Conselho Federal de Medicina (CFM) published a resolution addressing the anesthetic act and guiding the conduct of pre-anesthetic evaluation (PAE) and in 2017 revised these guidelines in a new resolution. The PAE is an important step in preparing the patient for elective surgical procedures. It refers to the moment when the anesthesiologist and patient have the opportunity to get to know each other, optimize the patient's clinical conditions and even request exams or consult other specialists when necessary. The prevalence and levels of anxiety, commonly generated by the expectation of the surgical-anesthetic procedure, tend to reduce with the PAE. This leads to fewer patients presenting to the operating room with arterial hypertension or arrhythmia, which are triggered by anxiety. It can be said that the implementation of the PAE directs screening processes and consequently reduces the patient's risk to unnecessary procedures or consultations. It also highlights the reduction in perioperative morbidity and mortality rates. By analyzing the dynamics of the surgical center, where the space is highly technological and contested by various surgical specialties, it is possible to associate the PAE with the reduction in cancellation rates of procedures and the proper use of space. Measuring sentiment is difficult and to assess anxiety, one can use complex questionnaires to small and objective scales. Some studies show how anxiety can contribute to increased postoperative pain, higher medication consumption, and longer hospitalization time. A possible tool to change this scenario would be the PAE, but its relationship with anxiety still needs to be further documented, especially in Brazil. Therefore, this project seeks to study the hypothesis that the PAE reduces anxiety levels, brings quality to the anesthetic-surgical experience, and improves perioperative morbidity indicators. This study aims to evaluate the impact of pre-anesthetic evaluation on perioperative surgical outcomes in patients of the orthopedic specialty undergoing procedures at the institution. It aims to identify the anxiety level of patients undergoing orthopedic surgery. This randomized clinical trial will be conducted at the Hospital de Base do Distrito Federal, Brasília, Distrito Federal, Brazil.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Other: control - anxiety evaluation before Pre-anesthetic
If allocated to the group control, the anxiety questionnaire will be applied, and then the pre-anesthetic evaluation will be conducted.
Other: control - anxiety evaluation before Pre-anesthetic
If allocated to the group control, the anxiety questionnaire will be applied, and then the pre-anesthetic evaluation will be conducted.
Other: group intervention - anxiety evaluation after Pre-anesthetic
If allocated to the group intervention, the first contact of the participant with the interviewer will be on the eve of surgery, in the ward. At that moment, the pre-anesthetic evaluation will be conducted. The next day, upon admission to the preoperative room, the anxiety questionnaire will be applied.
Active Comparator: intervention - anxiety evaluation after Pre-anesthetic
If allocated to the group intervention, the first contact of the participant with the interviewer will be on the eve of surgery, in the ward. At that moment, the pre-anesthetic evaluation will be conducted. The next day, upon admission to the preoperative room, the anxiety questionnaire will be applied.

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.
Outcome Measure
Measure Description
Time Frame
Pre operative anxiety levels
Time Frame: Before the procedure.
Assessment of pre operative anxiety levels using the State-Trait Anxiety Inventory - anxiety scale in patients who will or will not receive pre-anesthesia assessment in orthopedic surgeries. The score on this scale ranges from 10 to 40, with 10 being the calmest possible individual and 40 being the most anxious possible.
Before the procedure.

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
Assess anxiety levels using the Likert scale
Time Frame: Before the procedure
Assess anxiety levels using the Likert scale. This scale has a drawing of 5 faces that range from very anxious (on the left) to very calm (on the right)
