A Family Intervention for Delirium Prevention

Status Completed

Clinical Trial Summary

To address the feasibility of implementing a randomized, educational intervention to prevent delirium, directed at family members of hospitalized older (70 years of age or older) medical in-patients. Specifically rates of recruitment and acceptance rates of such an intervention to family members will be assessed. An estimate of the effect size of this intervention will also be calculated. This is a pilot study. The investigators hypothesize that this intervention will be feasible and agreeable to family members to perform, with acceptance rates exceeding 80%.

Clinical Trial Description

In a recent study in Chile, investigators randomized family members of admitted patients to an educational intervention to prevent delirium. Family members actively participated in a non-pharmacological intervention to prevent delirium. This has not been done in a North American environment, with different cultural and climactic factors.

This study will be a randomized controlled trial (pilot study) involving family members. Family members will be randomized to a control group or an educational intervention. The control group will receive a general brochure, outlining general health information published by the Ministry of Health. The intervention group will receive a specific brochure on details around delirium (what it is and how to prevent it), and then a brief educational session comprising a didactic session and to address any questions. This pilot study will examine the feasibility of doing this kind of intervention in a North American environment. The family-based intervention is similar to what was done in the Chilean study. It involves six elements including the educational session. The five other elements include: 1) family being present for extended periods (at least 5 hours if possible); 2) engaging in conversation with study patients for re-orientation to current time and current events; 3) avoiding sensory deprivation (ensuring hearing or visual aids and dentures are available as needed; 4) providing familiar objects to patients; 5) provision of a clock and calendar to the patient. The intervention brochure is similar to what was provided to family members as part of the original Chilean study (kindly provided to the principal investigator, M. Dasgupta, by the lead author of the Chilean study, Dr. F.T. Martinez). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
