Improvement Adherence to Clinical Practice Guidelines Using the Clinical Decision Support System in Patients With Hypertension and Atrial Fibrillation (INTELLECTII)

January 29, 2026 updated by: Prof. Dmitry Duplyakov FESC, Samara Regional Cardiology Dispensary

Active (CDSS) Control Blinded Multicenter, Cluster-randomized Trial of the Adherence to Clinical Practice Guidelines Using the Clinical Decision Support System in Patients With Hypertension and Atrial Fibrillation (INTELLECT II Trial)

The Clinical Decision Support Systems (CDSS) based on real clinical data and its own algorithms can help to make the right choice according to guidelines. The goal of the INTELLECT II study is to investigate treatment adherence to guidelines/science-based medicine and its impact on patient outcomes into two groups of doctors, clinical centers with standard care of treatment (control), and clinical centers using CDSS (active).

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.

Detailed Description

Hypertension and atrial fibrillation are 2 important public health priorities. There is a gap between evidence-based best management and actual clinical practice. To decrease this gap, clinical practice guidelines (CPGs), based on available evidence are employed. Clinical decision support system ("MedicBK") is a computer-based program that analyzes published evidence and provides prompts and reminders to assist health care providers in implementing clinical guidelines and science-based medicine at the point of care. The INTELLECT II trial is designed as a multicenter, cluster-randomized, single-blind, controlled study with blinded outcome assessment. Approximately 10 centers from Russia will be enrolled. Centers managing patients with symptomatic atrial fibrillation and/or hypertension will be randomized to either patient management with aid of CDSS ("MedicBK") or standard care.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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.

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
Compliance with AF/hypertension clinical practice guidelines
Time Frame: 1 month
number of patients treated in accordance with current ESC clinical guidelines for management atrial fibrillation evaluated by independent professionals compared with Clinical decision support system MedicBK
1 month

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
Total cardiovascular events
Time Frame: 6 months
total stroke or systemic embolism, total coronary heart disease, major bleeding, recurrence of atrial fibrillation, hospitalization or death from congestive heart failure and other significant vascular deaths
