Understanding, recognizing, and managing chronic critical illness syndrome

The long-term ICU patient: Which definition?

AIMS AND OBJECTIVES

To offer a review of the differing terminologies used by clinicians and researchers to describe the long-term intensive care unit (ICU) patient and the underlying propositions that align with this terminology.

BACKGROUND

Ongoing medical and technological advances in emergency and intensive care have resulted in improved survival of critically ill patients in recent decades. In addition, these advancements have also resulted in improved survival of complex critically ill patients who progress to a trajectory of prolonged critical illness, having protracted stays in the ICU. There is great variability in terminology used to define the long-term ICU patient. This lack of a common definition for long-term ICU patients is problematic, increasing their vulnerability and risk of care not being centred about their unique needs.

DESIGN

In this discursive article, we explore the terminology used to define the long-term ICU patient. An initial broad search of the literature across four electronic databases was conducted to identify common terminology used to define the long-term ICU patient. From here, seven definitions were identified and chosen for inclusion in the review as they meet inclusion criteria and clearly described a group of patients who have an extended ICU stay. The seven selected terms are as follows: prolonged mechanical ventilation; failure to wean; insertion of tracheostomy; chronically critically ill; persistent critical illness; persistent inflammatory-immunosuppressive and catabolic syndrome; and frailty. Following this a focused review of the literature with the selected terms was conducted to explore in greater detail the terminology.

DISCUSSION

The lack of clear definition for this patient group can potentiate their care needs being unmet. Acknowledgement of the need to clearly define this patient group is the first step to improve outcomes. Nursing is well positioned to recognise the different terminologies use to describe this group of patients and implement care to suit their unique clinical characteristics.

CONCLUSION AND RELEVANCE TO CLINICAL PRACTICE

Recognition and standardisation of these terms are an important priority to pave the way to improve care pathways and outcomes for this group of patients and their family.

Rethinking the intensive care environment: considering nature in nursing practice

AIMS AND OBJECTIVES

With consideration of an environmental concept, this paper explores evidence related to the negative impacts of the intensive care unit environment on patient outcomes and explores the potential counteracting benefits of 'nature-based' nursing interventions as a way to improve care outcomes.

BACKGROUND

The impact of the environment in which a patient is nursed has long been recognised as one determinant in patient outcomes. Whilst the contemporary intensive care unit environment contains many features that support the provision of the intensive therapies the patient requires, it can also be detrimental, especially for long-stay patients.

DESIGN

This narrative review considers theoretical and evidence-based literature that supports the adoption of nature-based nursing interventions in intensive care units.

METHODS

Research and theoretical literature from a diverse range of disciplines including nursing, medicine, psychology, architecture and environmental science were considered in relation to patient outcomes and intensive care nursing practice.

CONCLUSION

There are many nature-based interventions that intensive care unit nurses can implement into their nursing practice to counteract environmental stressors. These interventions can also improve the environment for patients' families and nurses.

RELEVANCE TO CLINICAL PRACTICE

Intensive care unit nurses must actively consider and manage the environment in which nursing occurs to facilitate the best patient outcomes.
