The system SHALL conform to function CPS.4.2.2 (Support for Patient-Specific Dosing and Warnings) to determine potential adverse reactions and render alerts or notifications when new medications are ordered. Dental Note: According to scope of practice, organizational policy, and/or jurisdictional law, can be, but is not limited to, an API to Rx module. Could also be entered manually and then cross-checked manually.

The system SHOULD provide the ability to render patient-specific medication dosing recommendations based on the patient's age and weight/body surface area.

\n
\n \n
\n CP.4.2.2#06\n \n MAY\n \n \n \n \n \n \n \n \n

The system MAY provide the ability to render patient-specific medication dosing recommendations based on previous patient experience (e.g., adverse reaction, type, and severity) with the same medication.

\n
\n \n
\n CP.4.2.2#07\n \n SHOULD\n \n \n \n \n \n \n \n \n

The system SHOULD provide the ability to determine weight-based medication dosing when doses are based on the patient's weight (e.g., mg/kg).

\n
\n \n
\n CP.4.2.2#08\n \n MAY\n \n \n \n \n \n \n \n \n

The system MAY provide the ability to determine and render medication orders in which the weight-specific dose suggested employs a starting range with incremental changes toward a target range (e.g., a target therapeutic index).

\n
\n \n
\n CP.4.2.2#09\n \n MAY\n \n \n \n \n \n \n \n \n

The system MAY render a notification requesting the parameters (e.g., coefficients, exponents, formulas) required to calculate the body surface area.

\n
\n \n
\n CP.4.2.2#10\n \n MAY\n \n \n \n \n \n \n \n \n

The system MAY provide the ability to determine and present dose ranges based on patient age.

\n
\n \n
\n CP.4.2.2#11\n \n MAY\n \n \n \n \n \n \n \n \n

The system MAY provide the ability to manage complex medication orders that include dosing based on either physical status or laboratory values.

\n
\n \n
\n CP.4.2.2#12\n \n SHALL\n \n \n \n \n \n \n \n \n

The system SHALL provide the ability to determine and present drug dosing based on custom compounded medication components.

\n
\n \n
\n CP.4.2.2#13\n \n SHOULD\n \n \n \n \n \n \n \n \n

The system SHOULD provide the ability to manage medication orders with patient-specific dose calculations (e.g., by weight, body surface area or genotype).
