Delirium | Other: Flexible Family Visitation Model (FFVM) Other: Restrictive Family Visitation Model (RFVM) | Not Applicable |
Study Type : | Interventional (Clinical Trial) |
Actual Enrollment : | 1650 participants |
Allocation: | Randomized |
Intervention Model: | Crossover Assignment |
Intervention Model Description: | The following interventions will be evaluated in the present study: restrictive family visitation model (intermittent visits according to local ICU regulation) and flexible family visitation model (12 consecutive hours per day). The unit of of concealed randomization is the ICU to minimize the risk of contamination, given that we intend to apply the intervention to the whole ICU multidisciplinary team. We will randomize ICUs to either an RFVM or to an FFVM as the initial intervention (T1). After enrollment of 25 ICU patients, there will be a 30-day period without recruitment to avoid contamination bias. After this period, each ICU will be assigned to an intervention contrary to that which initially receive (T2) until the enrollment of more 25 ICU patients. |

Active Comparator: Flexible Family Visitation Model (FFVM)
In the FFVM, two or fewer family members will be allowed to visit the patient for up to 12 consecutive hours each day. In addition to family visitation, patients will be allowed to receive social visits in specific time intervals (according local ICU regulation). To have access to the FFVM, family members of ICU patients will have to attend a structured meeting at ICU in which they will receive orientations about the ICU environment, common ICU treatments, rehabilitation and basic infection control practices, multidisciplinary work at ICU and palliative treatment. Social visitors will not be required to attend the structured meeting.
|
Other: Flexible Family Visitation Model (FFVM)
Visitation to ICU patients allowed during the period of 12 consecutive hours per day. |
Active Comparator: Restrictive Family Visitation Model (RFVM)
In the RFVM, patients will be allowed to receive restricted visits according routine ICU practices, but respecting the maximum limit of 4.5 hours of visitation per day. Visitors will not be required to attend the structured meeting. The length of ICU visits will be similar to those of social visits in the FFVM.
|
Other: Restrictive Family Visitation Model (RFVM)
Visitation to ICU patients allowed during intermittent periods according local ICU regulation. |
- Incidence of Delirium among ICU patients [ Time Frame: During ICU stay (from enrollment until ICU discharge, or death or a maximum of 30 days of follow-up) ]Incidence of delirium will be verified by trained intensive care professionals with the confusion assessment method for the ICU 2 times per day.
- Daily hazard of delirium among ICU patients [ Time Frame: During ICU stay (from enrollment until ICU discharge, or death or a maximum of 30 days of follow-up) ]The daily hazard of delirium will be analyzed using a joint survival model that accounts for the treatment effect on repeated daily indicator of delirium (Confusion Assessment Method for the ICU) within each patient and terminating event (death or discharge from the ICU).
- Antipsychotic use among ICU patients [ Time Frame: During ICU stay (from enrollment until ICU discharge, or death or a maximum of 30 days of follow-up) ]Need of antipsychotic use during ICU stay
- Need of mechanical restraints among ICU patients [ Time Frame: During ICU stay (from randomization until ICU discharge, or death, or a maximum of 30 days of follow-up) ]Need of mechanical restraints among ICU patients during ICU stay
- Coma-free days at day 7 among ICU patients [ Time Frame: During the first 7 days following patient enrollment. ]Days alive and free of coma (Richmond Agitation Sedation Scale -4 or -5) during ICU stay.
- Unplanned loss of invasive devices among ICU patients [ Time Frame: During ICU stay (from randomization until ICU discharge, or death, or a maximum of 30 days of follow-up) ]Unplanned loss of venous catheter, tube feeding or urinary catheter

- ICU-acquired pneumonia among ICU patients [ Time Frame: During ICU stay (from enrollment until ICU discharge, or death or a maximum of 30 days of follow-up) ]Pneumonia acquired after 48 hours of ICU admission.
- ICU-acquired bloodstream infection among ICU patients [ Time Frame: During ICU stay (from enrollment until ICU discharge, or death or a maximum of 30 days of follow-up) ]Bloodstream infection acquired after 48 hours of ICU admission.
- ICU-acquired urinary tract infection among ICU patients [ Time Frame: During ICU stay (from enrollment until ICU discharge, or death or a maximum of 30 days of follow-up) ]Urinary tract infection acquired after 48 hours of ICU admission.
- ICU length of stay among ICU patients [ Time Frame: During ICU stay (from enrollment until ICU discharge, or death or a maximum of 30 days of follow-up) ]Length of ICU stay in days
- All-cause hospital mortality among ICU patients [ Time Frame: During hospital stay (from enrollment until hospital discharge, or death or a maximum of 30 days of follow-up) ]rates of all-cause mortality during hospital stay
- Symptoms of anxiety among family members [ Time Frame: IOn the day of patient discharge from ICU, or death or a maximum of 30 days of follow-up. ]symptoms of anxiety among family members measured by the Hospital Anxiety and Depression scale
- Symptoms of depression among family members [ Time Frame: On the day of patient discharge from ICU, or death or a maximum of 30 days of follow-up. ]symptoms of depression among family members measured by the Hospital Anxiety and Depression scale
- Satisfaction among among family members [ Time Frame: On the day of patient discharge from ICU, or death or a maximum of 30 days of follow-up. ]Rates of patient's families satisfaction measured by the critical care family needs inventory
- Prevalence of Burnout Syndrome among ICU professionals [ Time Frame: It will be measured in two moments: within 15 days prior to the first ICU intervention and between the 15th and 30th days of the period in which no patient will be enrolled. ]Prevalence of Burnout Syndrome among ICU workers measured by the Maslach Burnout Inventory
- Satisfaction with the current ICU visiting policy among ICU professionals [ Time Frame: It will be measured between the 15th and 30th days of the period in which no patient will be enrolled. ]Satisfaction with the current ICU visiting policy among ICU professionals
- Any adverse event related to ICU visitation [ Time Frame: During ICU stay (from randomization until ICU discharge, or death, or a maximum of 30 days of follow-up) ]Any adverse event possible related to the ICU visitation model
