# Drug Prescription Workflow: Window Forms Description

The process of adding a medication involves two primary interface windows: the drug selection catalog and the detailed administration setup form.

#### 1. Drug Selection: "Reference book. Department forms"
After clicking the **+ Add** button on the main toolbar ([Screen Form Structure (структурное описание главной страницы листа назначений)](https://wiki.vistamed.ru/books/hierarchical-guide-to-vista-med-screen-forms-and-controls/page/screen-form-structure-strukturnoe-opisanie-glavnoi-stranicy-lista-naznacenii), the system opens the drug selection window.

*   **Functional Elements:**
    *   **Search Field:** A text box labeled "Enter the information to search for" to filter the catalog by name.
    *   **Selection Table:** Displays drugs with columns for **INN** (International Nonproprietary Name) and **Group** (e.g., "Anticancer drugs and immunomodulators", "Injection solutions").
*   **Action Buttons:**
    *   `Select`: Confirms the choice of a single drug.
    *   `Add to the selection (complex)`: Allows the physician to pick multiple items for a combined therapeutic regimen.

#### 2. Administration Setup: "Choosing the time of reception"
Once a drug is selected, the system opens a detailed configuration form.

*   **Patient Identification Header:** Displays the patient's name, **Case history number**, and vital anthropometric data: **Height**, **Weight**, and **BSA** (Body Surface Area).
*   **Drug Parameters (Left Panel):**
    *   **Dosage:** Fields for **Concentration**, **Single dose*** (marked as mandatory), and **UoM** (Unit of Measure, e.g., mg).
    *   *System Disclaimer:* A red warning states: "The choice of the dose of the assignment is the responsibility of the doctor".
    *   **Administration:** Dropdown for **Route of administration** (e.g., Oral use) and a field for **Duration (min.)**.
    *   **Period:** Selectors for **Start date of medication** and **End date of medication**.
    *   **Multiplicity:** The **Dates of assignment** dropdown defines the frequency (e.g., "daily").
    *   **Comment:** A text area for additional physician instructions.
*   **Scheduling (Center Panel):**
    *   **Time of Day:** A vertical list of hours (00:00 to 23:00). Selecting a time highlights it in **green**.
    *   The right-hand summary panel displays the specific **Time, date, and drug** details for the planned dose.
*   **Action Buttons:**
    *   `Assign`: Finalizes the prescription and adds it to the patient's record.
    *   `Close`: Cancels the operation without saving.

#### 3. Final Result in the Assignments List
Upon clicking `Assign`, the medication appears in the central table of the **Assignments list**.

*   **Status:** The entry is marked as **"assigned"**.
*   **Record Details:** The row displays the drug name, dosage, route, and the **Author** (e.g., "Doctor G. H.") with a precise timestamp of the assignment.
*   **Organization:** The prescription is automatically categorized under the appropriate summary block (e.g., "Summary list of drug prescriptions for the day").
