You can use the Lapsed Patients report to identify patients that have not had an appointment since a specified date.
The Lapsed Patients report is found in the Patients Report section.
The report is customisable by setting the date that the ‘Patient hasn’t visited since’. By clicking on the date a drop down calendar will appear where you can select the desired date. Clicking on any date in the calendar will set the report to that date and will show patients who have not visited since that particular date.
To export the patient list to a .CSV file to use it in Excel or another spreadsheet, click the the Export button in the the top right. This file has additional data on patients, more than is shown on the Dentally preview.
