Brief summary
REWINDER is a multinational, multicentre, non-interventional, retrospective study of patients treated with an oral antiplatelet (ticagrelor, prasugrel or clopidogrel) while in hospital after an acute coronary syndrome (ACS) event, to be conducted in Belgium and Luxembourg. Primary objective is to evaluate the actual treatment persistence with oral antiplatelets (OAP) after an ACS in the clinical practice in Belgium and Luxembourg. The main secondary objectives are to describe the most frequent reasons for OAP treatment switch, discontinuation or reinitiation; to identify the decisionmakers in the OAP treatment changes and to characterize the patient profile in terms of demographics, diagnosis, management strategies, comorbidities and concomitant medications to identify any association between patient profile and treatment duration.
Detailed description
Treatment of acute coronary syndrome (ACS) with oral antiplatelets (OAPs) is recommended for up to 12 months unless discontinuation is clinically indicated. Early discontinuation could result in an increased risk of cardiovascular death or myocardial infarction due to the patient's underlying disease. There are no robust data allowing to evaluate the treatment persistence with OAPs after ACS in the current practice in Belgium and Luxembourg at this time. It is currently unclear as to why patients discontinue, switch or reinitiate treatment and upon whose advice. A non-interventional study is needed to obtain reliable data on treatment persistence and reasons for discontinuation, switch or reinitiation of treatment.

The target sample size of the study is 500 patients.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The actual treatment persistence with OAP after an ACS in the clinical practice of Belgium and Luxembourg will be assessed by analysing the patient's 1-year follow data after discharge of an ACS event from hospital. Analysis will be descriptive. | up to 1 year | Patients discharged after an ACS event and fulfilling the entry criteria will be included in each centre. The retrospective observation period will be 1 year, starting on the date of discharge to home. Data on OAD treatment situation during the observation period will be collected. Number and proportion of patients having stopped treatment after 1, 3, 6, 9 & 12 month will be assessed and described. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The reasons for OAP treatment switch, discontinuation or re-initiation will be assessed by analysing the patient's 1-year follow data after discharge of an ACS event from hospital. Analysis will be descriptive. | up to 1 year | Patients discharged after an ACS event and fulfilling the entry criteria will be included in each centre. The retrospective observation period will be 1 year, starting on the date of discharge to home. Data on OAD treatment situation during the observation period will be collected. The reasons for switch, discontinuation & re-initiation (side-effects, drug-drug interactions, cost of treatment, patient's complaint, high bleeding risk & other) will be assessed and described. |
Other
| Measure | Time frame | Description |
|---|---|---|
| The decisionmakers in the oral antiplatelet (OAP) treatment changes will be identified by analysing the patient's 1-year follow data after discharge of an ACS event from hospital. Analysis will be descriptive. | up to 1 year | Patients discharged after an ACS event and fulfilling the entry criteria will be included in each centre. The retrospective observation period will be 1 year, starting on the date of discharge to home. Data on OAD treatment situation during the observation period will be collected. The decisionmakers will be identified and described (cardiologist interventional, cardiologist non interventional, surgeon, other specialist, dentist, GP, patient and/or family, other). |
| The patient profile will be characterized by analysing the patient's 1-year follow data after discharge of an ACS event from hospital. Analysis will be descriptive. | up to 1 year | Patients discharged after an ACS event and fulfilling the entry criteria will be included in each centre. The retrospective observation period will be 1 year, starting on the date of discharge to home. Data on OAD treatment situation during the observation period will be collected. Patient profile will be described in terms of demographics, diagnosis, management strategies, comorbidities and concomitant medications to identify any association between patient profile and treatment duration. |
