In this edition of our Guidelines Timelines, we explore the updates to the Prevention and Management of Pain, Anxiety, Agitation/Sedation, Delirium, Immobility, and Sleep Disruption in Adult Patients in the ICU clinical practice guidelines, which was recently updated in February 2025 by the Society of Critical Care Medicine (SCCM). This update builds upon the 2018 guidelines, offering more refined recommendations that address both the complexities of ICU patient care and the latest evidence in critical care management.

Approximately 5 million adults are admitted to ICUs annually in the United States, with a substantial proportion experiencing issues such as delirium (up to 80% of ICU patients) and chronic pain after their stay. Delirium, in particular, is a key issue that can lead to prolonged ICU admissions and can significantly affect long-term cognitive function and recovery. Moreover, anxiety and agitation are common, impacting patient comfort and complicating sedation and overall ICU management.

Effective prevention and management of these issues can dramatically improve outcomes for critically ill patients. The updated guidelines reflect current best practices and new research aimed at reducing the incidence of these conditions and improving the quality of care in the ICU.

Guideline Updates (2025)

Pain Management

  • The 2025 guideline emphasizes the importance of multimodal analgesia, incorporating a broader range of pharmacologic and non-pharmacologic interventions for pain relief. Opioid-sparing strategies have been strongly endorsed to minimize the risk of opioid-related side effects, including addiction and long-term dysfunction. A key update is the recommendation to use non-opioid analgesics, such as acetaminophen and gabapentinoids, more frequently in combination with regional anesthesia techniques.
  • The updated guideline also highlight the use of patient-controlled analgesia (PCA) as an effective method for managing post-operative pain in ICU patients, as well as emerging options like ketamine infusions for certain types of pain, such as those related to burns or major trauma.

Anxiety and Agitation/Sedation

  • In the 2025 guideline, there is a stronger emphasis on reducing sedation in favor of more awake and alert patients, as this has been shown to improve outcomes. Light sedation is now preferred over deep sedation, and where sedation is necessary, the guidelines recommend using short-acting agents like propofol or dexmedetomidine. These agents have been shown to reduce delirium and promote faster recovery times in ICU patients.
  • Additionally, the updated guideline encourages the use of non-pharmacological interventions such as relaxation techniques and music therapy, which have demonstrated effectiveness in reducing anxiety and agitation in ICU patients, especially during prolonged stays.

Delirium

  • The 2025 update highlights the importance of routine screening for delirium in all ICU patients using validated tools like the Confusion Assessment Method for the ICU (CAM-ICU). The guideline stresses early identification and management, with a focus on minimizing risk factors such as sedation and immobility. Pharmacologic treatments for delirium, such as the use of haloperidol, are no longer routinely recommended unless non-pharmacological interventions have proven ineffective. The updated guideline promotes a non-pharmacologic approach involving early mobilization, sleep optimization, and environmental modifications.

Immobility

  • The prevention of immobility remains a cornerstone of ICU care. In the 2025 guideline, there is a greater emphasis on early mobilization, with specific recommendations for physical therapy and nursing interventions designed to promote early movement, even in critically ill patients. Evidence now suggests that initiating mobility interventions as early as 24 to 48 hours can reduce the incidence of ICU-acquired weakness and improve overall patient recovery.
  • The guideline also recognize the challenges in mobilizing certain ICU patients, particularly those on mechanical ventilation or with significant comorbidities, but stress that the benefits of early movement far outweigh the risks. The 2025 version has expanded recommendations for mobilization techniques and specific therapies, such as passive range-of-motion exercises.

Sleep Disruption

  • The 2025 guideline places a greater focus on optimizing sleep for ICU patients, recognizing the profound impact that disrupted sleep has on recovery, delirium, and overall outcomes. The guidelines now recommend minimizing noise and light in the ICU, and whenever possible, creating a more restful environment by allowing patients to maintain their normal sleep-wake cycles. Non-pharmacological methods, including the use of earplugs and eye masks, have been incorporated into the new recommendations.
  • For patients with severe sleep disruptions, the guidelines support the careful use of pharmacological agents, such as melatonin, for managing sleep disturbances without inducing significant sedation or delirium.

The 2025 update to the Prevention and Management of Pain, Anxiety, Agitation/Sedation, Delirium, Immobility, and Sleep Disruption in Adult Patients in the ICU guideline reflects an increased focus on patient-centered care, with a balanced approach that integrates both pharmacologic and non-pharmacologic interventions. The guideline encourages the ICU team to work collaboratively to assess and manage these complex conditions, optimizing outcomes for critically ill patients and minimizing the long-term impact of their ICU stay.

By staying updated on these guidelines, healthcare providers can ensure the best care for their patients, reduce complications, and improve recovery trajectories. We encourage you to review the full guidelines and apply these new practices to enhance patient care in the ICU.
