Visits in Red Pill organise forms in the CRF into logical groupings. Mostly the visits will correspond to real world visits the subject makes, such as baseline and follow-up visits. They can also be used to group forms that are completed on demand (such as adverse events and other clinical events), and to sub-divide stages of a long real world visit (such as in hospital).

Visit dates

Within each visit you can optionally assign one of the date fields to be a visit date. The field chosen must be collected on a form in the visit, and it’s recommended this field is required. If you set a visit date, it will be used on the Red Pill visit summary report. This report shows, by site, how many subjects have completed this field, the range of dates entered, and an estimate of the number of subjects per month completing the visit date. As subjects accrue and move through the trial the report provides an overview of the flow of subjects through each stage.

Editing a baseline visit

Setting the visit date of a baseline visit to Date of examination. The visit is due as soon as the subject is added to the database.

Due dates

Visits can be scheduled by defining time-points when they become due. When visits are scheduled they show up on the Red Pill overdue forms page and due dates are shown in the subject details with overdue forms highlighted in red.

The time-point when a visit is due is set in the visit details. The Visit is due dropdown allows any date in the CRF to be selected. It also includes the date forms were added to Red Pill. For example, a baseline visit could become due 0 days after the subject details form is added. This would mean as soon as the subject is added to the database, all baseline forms would become due.

An offset field allows visits to become due a defined period after the visit date. For example, a 3 month follow-up visit might be set to become due 3 months after the randomisation form is added (i.e. date of randomisation). Or an in-hospital form might become due 3 days after date of surgery. Even if you’re not sure exactly when a visit will become due (e.g. a discharge visit), it is worth setting an offset to highlight visits that are outstanding after the visit would normally be expected to have taken place.

It is also possible to use arbitrary text to define when the visit is due. For example, you might describe an optional visit as due only if certain criteria are met. These text labels will be displayed in Red Pill but due dates will not be calculated and the visit will not appear on the overdue forms page.
