Incidence of Iatrogenic Diseases on Hospital's Emergency Consultations

Study Overview
=================
Brief Summary
-----------------
French population grows older year after year: 24.3% people were over 60 years old in 2006 against 20.6% in 2000 and the expected number might be over 33% in 2050. The elderly suffer from lots of illnesses, so they usually take lots of drugs. Therefore, this drug use is most likely to have adverse drug reactions. Finally, according to Health Ministry, the number of emergency department consultations doubled from 1996 to 2016. Consequently, it is interesting to study the impact of drug iatrogenic effects on emergency consultations. It would help to prevent these adverse drug reactions as we prescribe those drugs : First, do not harm.

Detailed Description
-----------------
This will be a retrospective study. The number of patients will be defined by the number of visits during a random draw of 10 emergency department consultation days between 21st June 2018 and 22nd September 2018 in Toulon - La Seyne sur Mer public hospital. There are between 100 and 300 emergency department consultations per day in this hospital so the estimated number of patients will be between 1000 and 3000. Every patient who came to hospital for a consultation in emergency department during this period of time will be included in the study except those who expressed their opposition to their data collection and treatment. Each patient will be anonymized with a code defined as follows : N(ame) L(ast name) 001 (chronological inclusion number) Information of the patients involved in adverse drug reactions will be extracted and a description of this patient sample will be made.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of patients coming to emergency department because of an adverse drug reaction | We will study each case and determine whether the consultation in the emergency department is due to adverse drug reaction or not.Number of patients having an emergency department consultation because of an adverse drug reaction divided by the total number of patients having an emergency department consultation during the same period of time. | 10 days (chosen at random between 21st June and 22nd September 2018) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Average of patient age among the patients consulting because of an adverse drug reaction | Average and standard deviation of patient age among the patients consulting in emergency department because of an adverse drug reaction. | 10 days | 
| Proportion of male and female patients consulting because of an adverse drug reaction | Number of male and female patients consulting in emergency department because of an adverse drug reaction divided by the total number of patients consulting in emergency department because of an adverse drug reaction. | 10 days | 
| Number of treatments administered to patients who consult because of an adverse drug reaction | Number of treatments patients were taking when they arrived in emergency department for a consultation because of an adverse drug reaction | 1 day |
