A Prospective Observational Study Using the FAM-CAM
Family Involvement in ICU Delirium Assessment: A Prospective Observational Study Using the FAM-CAM
The goal of this observational study is to learn whether family members can help identify signs of delirium in adult patients who are staying in the intensive care unit, or ICU. Delirium is a sudden change in attention, thinking, or awareness that can happen during serious illness.
The main question it aims to answer is:
Can family members notice possible signs of delirium that may not be found during routine ICU delirium screening? Participants will receive their usual medical care. Family members who know the patient well will complete a short delirium assessment called the FAM-CAM after visiting the patient. Nurses will continue to perform routine ICU delirium screening using the ICDSC as part of usual care. The study team will compare the family member's assessment with the nurse's routine assessment to see whether family observations provide additional helpful information.
Family members may complete the assessment for up to 3 days while the patient is in the ICU.

Delirium Assessment Using FAM-CAM, ICDSC, and CAM-ICU
In this observational study, participants will not receive any study treatment or experimental intervention. The study procedures include daily delirium assessments and routine clinical data collection. Family members will complete one FAM-CAM assessment each day as soon as possible after the ICU visiting period ends, usually between 15:30 and 16:00. The family member will fill out the assessment form, and study staff will check the form for completeness and accuracy and record the time the assessment is completed. Nurses will complete one ICDSC assessment each day as soon as possible after the ICU visiting period ends, usually between 15:30 and 16:00. The nurse will record the assessment result and the time the assessment is completed. Trained research staff will complete one CAM-ICU assessment within a prespecified time window, close to the time of the family FAM-CAM assessment and the nurse ICDSC assessment. The CAM-ICU result and assessment time will be recorded. |

Overall Agreement Among Family FAM-CAM, Nurse ICDSC, and Professional Research Staff CAM-ICU Assessments
Tidsramme: once daily between 3:30 PM and 4:00 PM
|
This outcome will measure the level of agreement among the three assessment methods in the same patient and within the same general time frame.During the ICU phase, paired assessment data will be created according to the pairing rules described for the primary outcome.
The results of FAM-CAM, ICDSC, and CAM-ICU will be classified as either "positive" or "negative."Agreement
will be evaluated using Cohen's kappa coefficient as the main measure.
The overall agreement rate, positive agreement rate, and negative agreement rate will also be reported as additional measures, together with 95% confidence intervals.

Effect of Older Age, Low Education Level, Language or Dialect Communication Barriers, and Family Members' Delirium Knowledge on Assessment Disagreement
Tidsramme: once daily between 3:30 PM and 4:00 PM
|
This outcome measure will evaluate the effect of older age, defined as age 65 years or older; low education level, defined as primary school education or below; language or dialect communication barriers, recorded as present or absent; and family members' delirium knowledge questionnaire scores on disagreement among delirium assessments. Assessment disagreement is defined as inconsistent delirium classification among the family-completed FAM-CAM, nurse-completed ICDSC, and CAM-ICU completed by trained research staff in the same patient and within a similar assessment time frame. The study will compare the proportion of disagreement events across different subgroups and will use regression analysis to evaluate the strength of association between these factors and assessment disagreement. Results will be reported as odds ratios with 95% confidence intervals. |
