Results are provided on an as is basis and are not guaranteed to be accurate or complete. ## Summary of Dosage Concepts This content outlines how to enhance the efficiency of healthcare representatives by configuring dosage specifications for medication products. It details the key components of dosages, including dosage specifications, characteristics, and characteristic groups, and explains their interconnections. Show full answer Show less ## Key Features * **Dosage Specifications:** These consist of diagnosis details and dosage characteristics associated with a medication product. Adding a dosage specification automatically creates a corresponding dosage definition for use in requests. * **Dosage Characteristics:** These define the attributes of dosage specifications and include features such as restrictions on characteristic values (e.g., dosage quantity). Each characteristic is unique within its group. * **Characteristic Groups:** These groups comprise similar characteristics that map to fields in the Dosage details section of the Medication Prescription form, ensuring structured data input. * **Mapping:** Dosage characteristics must be mapped to fields in the Dosage details section to be displayed properly. Extensions like the DosageCharacteristicsMapper can be used for this configuration. ## Key Outcomes By effectively configuring dosage specifications and characteristics, ServiceNow customers can minimize manual errors and streamline healthcare processes. The automatic creation of dosage variables enhances the Medication Prescription form's usability, allowing for more accurate dosage management and improved patient care. You can increase the efficiency of healthcare representatives and reduce manual errors by configuring dosage specifications for a medication product associated with a program A dosage comprises the following key components: * [Dosage specifications](https://www.servicenow.com/docs/9KU8OMGejAZrDJCSnVo~yw#hcls-dosage-concept__section_xwz_z3x_htb) * [Dosage characteristics](https://www.servicenow.com/docs/9KU8OMGejAZrDJCSnVo~yw#hcls-dosage-concept__section_ur1_bjx_htb) * [Dosage characteristic groups](https://www.servicenow.com/docs/9KU8OMGejAZrDJCSnVo~yw#hcls-dosage-concept__section_cl5_qjx_htb) {#hcls-dosage-concept__ul_j1x_1qx_htb} To learn about how dosage components are linked to each other, see [Dosage characteristics mapping](https://www.servicenow.com/docs/9KU8OMGejAZrDJCSnVo~yw#hcls-dosage-concept__section_fwn_cjx_htb). ## Dosage specifications {#hcls-dosage-concept__section_xwz_z3x_htb} A dosage specification consists of diagnosis details and dosage characteristics of a medication product associated with a program. For more information, see [Dosage specification table](https://www.servicenow.com/docs/RyzI7MzpoAEmQmzHCuMwWA "The Dosage specification [sn_hcls_dosage_specification] table stores the information about medication product dosage associated with a program."). Note: When you add a dosage specification for a medication product, an equivalent dosage definition entry is added in the application. A dosage definition models a dosage specification for use as a request definition parameter. For more information, see [Dosage definition table](https://www.servicenow.com/docs/HgJr2cAIshzr_6MMWNghXw "The Dosage definition [sn_hcls_dosage_definition] table models the Dosage specification [sn_hcls_dosage_specification] table for use as a request definition parameter."). ## Dosage characteristics {#hcls-dosage-concept__section_ur1_bjx_htb} A dosage characteristic defines the attributes of a dosage specification. A dosage characteristic has the following features: * Is included in the Dosage characteristics characteristic group and a characteristic group mapped to a field in the Dosage details section of a medication prescription form. * Can include a characteristic option to restrict the characteristic value. For example, to restrict the quantity of dosage. Else, when a characteristic option isn't specified for a dosage characteristic, a healthcare representative can later fill the corresponding field value in the Dosage details section of the Medication Prescription form. * Is unique for a characteristic group when multiple entries for a characteristic are created. For example, when a dosage specification includes quantity characteristic as quantity per month supply, you can't add another characteristic for the quantity per week supply. * Similar dosage characteristics are stored in the Characteristic Group \[sn_prd_pm_configuration\] table. {#hcls-dosage-concept__ul_dkf_2fx_htb} Note: For each dosage characteristic added to a dosage specification, a dosage variable is automatically created. A dosage variable is displayed as a dynamic field in the Dosage characteristics section of the Medication Prescription form. For more information, see [Dosage variable table](https://www.servicenow.com/docs/Smd5r7XPHph6eLR0r8gCvg "The Dosage variable [sn_hcls_dosage_variable] table stores the variables configured for a dosage specification displayed on the Medication Prescription form of a Healthcare and Life Sciences Service Management application."). ## Characteristic groups for a dosage {#hcls-dosage-concept__section_cl5_qjx_htb} A dosage characteristic group comprises the similar characteristics of a dosage specification. Each dosage characteristic maps to a field in the Dosage details section of the Medication Prescription form. For a dosage characteristic to appear with a dosage specification, you must include it in the following characteristic groups: * A characteristic group mapped to a field in the Dosage details section of a medication prescription form. * The Dosage characteristics characteristic group available by default. {#hcls-dosage-concept__ul_r14_vpx_htb} ## Dosage characteristics mapping {#hcls-dosage-concept__section_fwn_cjx_htb} You map a dosage characteristic group with a field in the Dosage details section of the Medication Prescription form. You can use the DosageCharacteristicsMapper extension point to configure the mapping between a characteristic group and a field in the Dosage details section of the Medication Prescription form. For more information, see [Configure the mapping between a dosage characteristic and a dosage details field](https://www.servicenow.com/docs/OHYPHtMwvnuY_7EuHtSNZw "Use scripted extension points to decide which dosage characteristics are mapped to the fields on the Dosage details section of a Medication Prescription form."). By default, the application provides a few sample characteristics and characteristic groups for the Healthcare and Life Sciences workflows that you can as a reference when creating a dosage specification. The following figure illustrates the default mapping between characteristics and characteristic groups of a dosage specification, and the mapping between characteristic group of a dosage specification and dosage details fields of a medication prescription.Figure 1.
