## Add Visits to Visit Groups/Phases

To add visits to your schedule, complete the steps below:

1. Within the Schedule Editor, navigate to the **Visits** tab. Your defined groups/phases are listed on the left.
2. Select **Edit Visits** to add to or modify the visits in a group.
3. Select **+ Create Visit** (or press Enter after tabbing to link) to add a new row/visit to the table.
4. Complete each visit’s details: 
  - **Name:** Enter the name of the visit (ex.,_Screening Visit, Baseline, Cycle 1 Day 8_).
  - **Offset Type:** Defines how or if this visit relates to other visits: 
    - **None:** Visits that can be scheduled independently. Generally, this offset type is recommended for the first visit in a phase.
    - **Previous Visit:** The visit is scheduled relative to the visit immediately preceding it in the sequence, making the previous visit the anchoring visit. This is particularly useful when different branches converge and the exact preceding visit might vary.
    - **Specific Visit:** The visit is scheduled relative to a specific, selected visit anywhere earlier in the schedule (ex., _Day 1 of Treatment_), making this selected specific visit the anchoring visit. For visits with specific timing relationships, _Specific Visit_ offsets are preferred to _Previous Visit_.

  - **Target Date and Anchor Visit:** Defines the required timing for the appointment to occur relative to the specific (or previous) visit selected as the anchoring visit.
  - **Early/Late:** These fields define the allowable window (in days, plus or minus) around the target date. For example, if a visit is targeted for 14 days after a specific visit, but can occur between 4 days before or after the target date, you would set _Early_ to -4, and _Late_ to +4. 
    - **Best Practice for Timing** : CTMS uses days for precise scheduling. While protocols may state weeks or months, it’s recommended to convert these to days to avoid assumptions (ex., 7-day weeks, 30-day months) that can lead to inaccuracies.

5. When you have followed these steps for each visit in each group, Select **Save**.

- **Note** : You can **move a visit** to a different group by selecting the related checkmark and selecting the _Move to_ button.

## Ad Hoc Visits

CTMS automatically includes three default ad hoc visit types that cannot be removed:

- Unscheduled Visits
- Adverse Events
- Early Term.

Use the steps above to add customized ad hoc visits to your schedule.
