Joanna L. Stollings, PharmD, FCCP, FCCM, and Devin N. Holden, PharmD, BCPS, BCCCP, summarize how pharmacists can play an important role in the development and implementation of each element of the ICU Liberation Bundle (A-F).

As part of the multiprofessional team, pharmacists are logical champions of implementing and maintaining the ICU Liberation Bundle (A-F). The bundle has shown to improve short- and long-term outcomes for patients during their ICU stay and beyond. It can be applied to every patient, every day, by the full team. Pharmacists’ role in ICU Liberation has been demonstrated in numerous studies.1-11 Key papers from the ICU Liberation Collaborative providing implementation and sustainability guidance have also highlighted the role of the ICU pharmacist.12-14
 
Here we summarize how pharmacists can play an important role in the implementation and maintenance of each element of the ICU Liberation Bundle:
 

A Element: Assess, Prevent, and Manage Pain

  • Educate staff on the importance of continual assessment and its relationship to medication administration and titration.
  • Ensure that patient assessments are performed using a validated tool, such as the Numeric Pain Scale in patients who can verbalize or the Critical Care Pain Observation Tool or Behavioral Pain Scale in nonverbal patients.
  • Aid in determining the optimal analgesic regimen for each patient considering the patient’s renal function, liver function, past medical history, and medications prior to admission.
  • Facilitate transition to oral therapy and evaluate for indications to continue medications daily, especially during transitions of care, while minimizing side effects and opioid exposure where possible.
  • Aid in developing evidence-based protocols to treat pain as part of the multiprofessional team.  

B Element: Both Spontaneous Awakening Trials (SATs) and Spontaneous Breathing Trials (SBTs)

  • Assist in screening for and confirming the coordination of SATs and SBTs daily.
  • Educate members of the multiprofessional team including physicians, nurses, advanced practice providers, and respiratory therapists on the importance of conducting and coordinating SATs and SBTs.
  • Help in developing a protocol with inclusion and exclusion criteria for the SAT and SBT safety screen and conduction.  

C Element: Choice of Analgesia and Sedation

  • Assess for appropriate level of arousal target daily using either the Richmond Agitation-Sedation Scale (RASS) or Sedation-Agitation Scale (SAS).
  • Ensure coordination of the patient’s actual level of arousal with the targeted level of arousal and apply necessary interventions if needed.
  • Recommend the use of light sedation with dexmedetomidine or propofol or no sedation as compared to benzodiazepine-based sedation.
  • Ensure that the pharmacist can prescribe to maximize the safety and efficiency of pharmacologic regimens at sites with pharmacy collaborative practice agreements.
  • Aid in developing evidence-based protocols to treat agitation as part of the multiprofessional team.  

D Element: Delirium: Assess, Prevent, and Manage

  • Ensure that patient assessments are performed using a validated tool such as the Confusion Assessment Method for the ICU (CAM-ICU) or Intensive Care Delirium Screening Checklist (ICDSC).
  • Review medication lists daily to minimize deliriogenic medications.
  • Recommend nonpharmacologic strategies to prevent and treat delirium.
  • Aid in developing evidence-based protocols to prevent and minimize delirium as part of the multiprofessional team.

E Element: Early Mobility and Exercise

  • Evaluate the patient’s medication list daily to aid in minimizing sedating or deliriogenic medications that may preclude early mobility.
  • Identify patients who are candidates for early mobility and recommend that the team consult physical and occupational therapy.
  • Orchestrate the administration of nonopioid-based pain relievers to facilitate successful physical and occupational therapy patient experiences.
  • Aid in developing evidence-based protocols to triage physical therapy among physical therapists, occupational therapists, nurses, and family based on the patient’s clinical status.  

F Element: Family Engagement and Empowerment

  • Educate the patient and the the patient’s support system.
  • Aid in incorporating family members into multiprofessional rounds.
  • Assist in educating the patient and the patient’s family on the importance of using the ICU Liberation Bundle and the prevention of post-intensive care syndrome (PICS).

With the necessary knowledge, training, and support from the multiprofessional team, ICU pharmacists are ideally positioned to serve many important roles as part of ICU Liberation Bundle implementation and maintenance. Pharmacists’ roles go beyond the C element; they play a role in implementing and maintaining all parts of the ICU Liberation Bundle.
