richmond_agitation_sedation_scale: Richmond Agitation-Sedation Scale (RASS)

Description

Calculates the RASS score, a validated tool to assess the level of sedation and agitation in hospitalized patients. It uses a logic-based approach starting with observation of behavior, followed by response to voice, and finally response to physical stimulation.

Usage

richmond_agitation_sedation_scale(observed_behavior,
                                  voice_stimulation = "not_applicable",
                                  physical_stimulation = "not_applicable")

Value

A list containing:

RASS_Score

The calculated score (integer from -5 to +4).

Term

The clinical term associated with the score (e.g., "Light Sedation").

Description

Detailed description of the patient's state.

Arguments

observed_behavior

String. The patient's spontaneous behavior. Options: "combative" (+4) "very_agitated" (+3) "agitated" (+2) "restless" (+1) "alert_and_calm" (0) "not_alert" (Proceed to voice stimulation)

voice_stimulation

String. Response to verbal stimulation (e.g., calling name, asking to open eyes). Required if observed_behavior is "not_alert". Options: "eye_contact_gt_10s" (-1) "eye_contact_lt_10s" (-2) "movement_no_eye_contact" (-3) "no_response" (Proceed to physical stimulation) "not_applicable" (Default)

physical_stimulation

String. Response to physical stimulation (e.g., shoulder shake, sternal rub). Required if no response to voice. Options: "movement_or_eye_opening" (-4) "no_response" (-5) "not_applicable" (Default)
