Effects of a Dementia-friendly Program

Effects of a Dementia-friendly Program on Detection and Management of Patients With Cognitive Impairment and Delirium in Acute-care Hospital Units: a Non-equivalent Control Group Design

Frail older persons with cognitive impairment are at special risk of experiencing delirium during acute hospitalisation. The purpose of this study was to investigate whether a dementia-friendly hospital program contributes to improved detection and management of patients with cognitive impairment and delirium.

Study Overview

• Status: Completed
• Conditions: Delirium; Cognitive Impairment; Dementia
• Intervention / Treatment: Other: The dementia friendly program

Detailed Description

Study design This study, has a non-equivalent control group design and a historical control Group. The Control group received usual care and the experimental group received usual care plus the dementia-friendly program.

One Group received care after implementing the dementia-friendly hospital program. The study is performed at two medical wards at a large acute-care hospital in Norway. A medical pulmonary ward and a cardiac ward participated.

Data Collection:

Demographic data included age, gender, place of residence (home, adapted housing, institution), and family/relative network, and were obtained upon admission to the study.

Medical data included cause of admission, active medical diagnoses, medications and medical treatment, and were obtained both at admission and from their electronic medical records after discharge.

Cognitive Impairment and delirium were assessed with two different screening tools: the Four Assessment Test (4AT) and the Confusion Assessment Method (CAM).

For all patients with a positive 4AT (≥1) or identified cognitive impairment during their hospital stays, a thorough review of the patient's journal was conducted upon discharge to record if, in case of yes, which type of preventive or treatment measures according to the dementia-friendly program, the patients had received during their stays.

Intervention / Treatment

OTHER: The dementia friendly hospital program; The dementia-friendly hospital program comprised three parts; 1) Educational program for health practitioners to increase the staff's knowledge and awareness of patients with cognitive impairment and/or delirium; 2) Screening, for early identification of cognitive impairment and delirium, using the Four Assessment Test (4AT); 3) Delirium risk factor modification and management for patients defined with potential cognitive impairment and risk of delirium, implying that risk factor modifications should be implemented in the patient's care plan. For patients with suspected delirium, the program promoted an additional delirium management plan.

Other: The dementia friendly program; Implementation of a systematic screening and risk modification and management plan, to identify and enhance the management of patients with cognitive impairment and risk of delirium.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Detection of patients with cognitive impairment	Proportion of patients identified with cognitive impairment during the hospital stay, documented in the electronic Medical record. Difference between the control group and the intervention group. Patients were assessed with The Four Assessment Test at admission and during the stay at the participating wards. Furthermore, documentation of cognitive impairment in the electronic medical journal during the stay were assessed after discharge.	During the stay at the participating wards, assessed from the electronical medical record within 6 months after discharge
Management of patients with cognitive impairment and delirium	Proportion of patients identified with cognitive impairment, delirium or at risk of delirium who has documented interventions to prevent and/or treat delirium, according to the implemented dementia-friendly program.Differences between the control group and the intervention group.	During the stay at the participating wards, assessed from the electronical medical record within 6 months after discharge

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Screening within 24 hours	Proportion of patients screened with The Four Assessment Test within 24 after hours after admission to the ward. Differences between the control group and the intervention group.	Within 24 hours after admission to the ward
Use of antipsychotics, hypnotics and sedatives	Proportion of patients with cognitive impairment given doses of antipsychotics, hypnotics and sedatives during the stay at the participating wards. Differences between the control group and the intervention group. Given doses of antipsychotics, hypnotics and sedatives during the stay at the participating wards registered in the electronic medical journal, were assessed after discharge.	During the stay at the participating wards, assessed from the electronical medical record within 6 months after discharge
Use of medications not recommended for the patient group	Proportion of patients with cognitive impairment who uses medications which are not recommended for the patient group. Differences between the control group and the intervention group.	During the stay at the participating wards, assessed from the electronical medical record within 6 months after discharge
Departure to rehabilitation or nursing home	Proportion of patients with departure to rehabilitation or nursing home. Departure to care level were assessed from the electronic medical journal after discharge.Differences between the control group and the intervention group.	Assessed from the electronical medical record, within 6 month after discharge
Length of hospital stay	Mean number of days at the hospital stay.Length of hospital stay were collected from the electronic medical journal after discharge.Differences between the control group and the intervention group.	Assessed from the electronical medical record, within 6 month after discharge
Delirium	Proportion of patients diagnosed with delirium. Delirium diagnosis documented during the stay at the participating wards were collected from the electronical medical record after discharge. Differences between the control group and the intervention group.	Assessed from the electronical medical record, within 6 month after discharge
30-day readmission to the hospital	Proportion of patients who are readmitted to the hospital within 30 days after discharge from the hospital. Differences between the control group and the intervention group.	Readmissions to the hospital were assessed from the electronical medical record 30 days after discharge.
30-day mortality	Proportion of mortality in the patient group within 30 days after discharge from the hospital. Differences between the control group and the intervention group.	Mortality were assessed from the electronical medical record 30 days after discharge.
