Physiological Changes in Adult Intensive Care Patients Upon Contact With Their Primary Caregiver (CARE-ICU): A Randomized Clinical Trial

Patients admitted to intensive care units are exposed to multiple environmental and clinical factors that may affect their physiological responses. This randomized controlled trial aims to evaluate the effect of physical contact with the primary caregiver on physiological parameters in adult patients hospitalized in an intensive care unit.

Descrição detalhada

This study is a randomized, controlled, parallel-group, double-blind clinical trial designed to evaluate the effect of therapeutic contact provided by the primary caregiver on physiological parameters in adult intensive care unit (ICU) patients. Participants will be randomly assigned in a 1:1 ratio to either the intervention group (therapeutic contact) or the control group (no therapeutic contact) using block randomization generated by an independent external advisor. Allocation concealment will be ensured through the use of sequentially numbered, opaque, sealed, tamper-evident envelopes.

Sample size was calculated for the comparison of means between two independent groups using a 95% confidence level (α = 0.05), 80% statistical power (β = 0.20), a standard deviation of 7.6, and a minimum clinically meaningful difference of 5 units. The estimated sample size was 36 participants per group. After adjustment for an anticipated 10% attrition rate, a total of 80 participants (40 per group) will be enrolled.

Physiological outcomes include heart rate, systolic blood pressure, diastolic blood pressure, respiratory rate, oxygen saturation, and body temperature. Measurements will be obtained using a bedside multiparameter monitor and recorded on a standardized physiological data collection form. Equipment calibration will be verified before each measurement. Outcomes will be assessed 10 minutes before the caregiver visit, 10 minutes after the start of the visit, and 10 minutes after completion of the visit.

Changes in physiological outcomes will be calculated as the difference between baseline measurements and subsequent assessments. Data analysis will be performed using IBM SPSS Statistics Version 29.0 (IBM Corp., Armonk, NY, USA). Continuous variables will be summarized using means and standard deviations or medians and interquartile ranges, according to data distribution. Categorical variables will be summarized using frequencies and percentages. Normality will be evaluated using the Kolmogorov-Smirnov test. For each physiological outcome, change scores will be calculated by subtracting baseline values from measurements obtained during and after the caregiver visit. Mean changes between the intervention and control groups will be compared using the independent-samples t-test or the Mann-Whitney U test, as appropriate. Effect sizes will be estimated using Cohen's d. Statistical significance will be established at p < 0.05. The study was approved by the Research Ethics Committee of the Instituto Nacional de Enfermedades Respiratorias "Ismael Cosío Villegas". The trial will be conducted in accordance with the Declaration of Helsinki and applicable Mexican regulations governing health research. Written informed consent will be obtained from all participants or their legally authorized representatives before enrollment. Adverse events will be documented and reported to the institutional ethics committee and ClinicalTrials.gov according to applicable regulatory requirements.

Intervenção / Tratamento
Experimental: Intervention
Therapeutic physical contact provided by their primary caregiver
Outro: Standardized therapeutic physical contact

During the pre-visit phase (30 minutes), caregivers will receive information about the study, patient's condition, infection control procedures, and training on the standardized contact protocol.

During the visit phase (20 min), the caregiver will greet the patient in a customary manner (1 min); provide a gentle massage to the dorsal surface of the hand while discussing positive events of the day (6 min); gently touch the patient's forehead with the fingertips while recalling pleasant memories (3 min); gently massage the patient's cheek using the fingertips while providing encouraging and positive messages (3 minutes); massage the palm of the patient's hand using circular movements while discussing goals to be achieved after hospital discharge (4 min); and holding the patient's hand and expressing wishes for recovery and discharge (3 min).

Following the visit, caregivers will be given the opportunity to share observations, comments, and feedback regarding the intervention experience.
