Risk for Short-term Adverse Events in Older Users in the Emergency Department

Study Overview
=================
Brief Summary
-----------------
The study evaluates the performance criteria of abnormal PRISMA-7 score, length of stay in Emergency department and in hospital, and hospital admission in older Emergency department users.

Detailed Description
-----------------
In Quebec, Canada, the Program of Research on Integration of services for the Maintenance of Autonomy (PRISMA-7) is the Ministry of Health and Social Services' reference tool for the frailty assessment of older Emergency department users. This tool has been initially developed and validated to assess disabilities in older community dwellers with the aim to quickly identify older individuals at risk for disabilities and who should undergo a comprehensive assessment. PRISMA-7 has a high sensitivity for identifying frailty in older community dwellers but its performance criteria for this goal has never been examined in older Emergency Department users. Recently, a systematic review underscored that PRISMA-7 has all characteristics for being a usable clinical tool in Emergency department because it is a brief (i.e., <5 min), simple and multidimensionality assessment. PRISMA-7 is composed of 7 questions assessing health and functionality of older adults and stratifies risk for disability in two levels: low versus high. PRISMA-7 is a prognostic tool for disabilities.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Observational<br>ER2 is a simple and standardized clinical tool composed of two sequential components: an assessment followed by recommendations for intervention. The assessment component of ER2 consists of 6 very simple closed-ended format questions (i.e., yes versus no) which are: Age category (≥ 85), male, polypharmacy (≥ 5 different medications per day), use of formal (health care or social professional) and/or informal (family and/or friend) home support, use of a walking aid regardless of its type, and temporal disorientation (inability to give the current month and/or year). A score of five points is assigned to the items use of walking aid and temporal disorientation, whereas, for the other items, the assigned score is one point. The weighting of points for ER2 items is based on the results of our previous studies (21-24). Scores range from 0 (lowest risk) to 14 (highest risk). ER2 scores stratify the risk for short-term ED adverse events into three levels: low, moderate and high. | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Length of hospital stay | The length of hospital stay is defined as the average number of days that patients spend in hospital. It will be used the ER2 tool ( Emergency Room Evaluation and Recommendation) to calculate the length of hospital stay. | around 12 months |
