Advances in intensive care medicine have created a new disease called the chronic critical illness. While a significant proportion of severely ill patients who twenty years ago would have died survive the acute phase, they remain heavily dependent on intensive care for a prolonged period of time. These patients, who can be called “Patient Long Séjour” in French (PLS) or Prolonged Length of Stay patients in English, develop specific health issues that are still poorly recognised. They require special care, which differs from treatments that are given during the acute phase of their illness. A multidisciplinary team dedicated to ensuring their management and follow-up acquired a wide range of knowledge and expertise about these PLSs. Many new monitoring tools and diverse human approaches were implemented to ensure that care was targeted to these patients’ needs. This multimodal care management aims to optimise the patients’ and their families’ quality of life during and following intensive care, whilst maintaining the motivation of the healthcare team of the unit. The purpose of this article is to present new management techniques to hospital and ambulatory caregivers, physicians and nurses, who may be taking care of such patients.
Keywords: quality of life, outcome, complications, length of stay, prolonged ICU stay, patient long séjour.
Advances in intensive care medicine allow patients to survive serious health insults. However, their survival involves a cost for the patients who themselves suffer, their family members and society . Indeed, many such patients require a prolonged stay in the intensive care unit (ICU) because of difficult weaning or repeated sepsis and represent an increasing new population of ICU patients called “the chronic critically ill” or “Patients Long Séjour (PLS)” in French meaning “Prolonged Length of Stay patient”. Chronic critical illness is a devastating condition in which mortality exceeds that of most malignancies, and for most survivors functional dependence persists [2–4], consisting of physical impairments, pain and significant psychosocial disorders [5, 6]. This article addresses the specific care aiming to improve the outcome of PLS.
A few ICU caregivers realised in 2006 that such patients needed to be managed differently from patients in the acute phase . An interdisciplinary team composed of physicians, nurses, nurse assistants, physiotherapists and teachers, developed a new approach for PLS care. The group sought their particular requirements, innovated new specific monitoring tools and continues to develop therapeutic approaches adapted to their special needs. In parallel, it created a network in close cooperation with other specialists, i.e. orthopaedists, dieticians, neuropsychologists and a speech therapist, in order to extend their knowledge and adapt the therapies during the prolonged stay of PLSs in the ICU. This approach includes a palliative attitude, in accordance with the Swiss Academy of Medical Sciences , which needs to be adopted very early for each patient admitted into the ICU whatever his/her risk of dying. Indeed, the suffering of these patients should be duly cared for .
This article presents the multimodal approach developed up to the present in order to optimise the care of PLSs and aiming eventually to improve their future quality of life.
Prolonged-stay patients and their characteristics
The definition of the “chronically critically ill patient” was coined by Girard and Raffin in 1985 in an article describing a set of patients who remained dependent on vital support treatments after an acute critical disease that required admission to the ICU . In Geneva, patients who should benefit from specific PLS care were defined as those with a length of stay in the ICU of ≥7 days . The second criterion for categorising a patient as a PLS was the necessity for support by sophisticated means available only in the ICU (the hallmark of chronic critical illness is respiratory failure requiring prolonged dependence on mechanical ventilation) (fig. 1). Patients in palliative care or nearing the end of life were excluded.
The former account for about 12 to 18% of the 2 500 patients admitted to the Geneva ICU each year, stay as long as 13.8 days (all patients: 3.8 days) and consume up to 52% of the ICU resources. They are not older than the ICU general population (60 ± 19 years). Their mortality in the ICU was assessed to be around 15% compared with 8–12% of the general ICU population. Nevertheless, since more than a third of PLSs eventually return home, the ICU caregivers should acknowledge the existence of this group and pay special attention to their care.
Their specific problems are summarised in table 1. Their symptoms differ from those of patients in the acute phase, will continue far beyond the ICU and may even impact their future life.
These patients require from caregivers not only expertise in the advanced technology of intensive medicine, but also extraordinary skill in human relationships. Their complex situations and the long stay in the special environment of intensive care can be a source of conflict amongst family members, amongst caregivers and between family members and caregivers, as was shown in the study from Studdert . Nearly one-third of all ICU patients with prolonged stays experienced at least one conflict associated with life-sustaining treatment, disagreements about the plan of care, or poor communication. Also, conflicts are associated with burnout of caregivers, which in turn can be associated with conflicts with nurses, colleagues or patients’ families .
An attempt to pool these patients in a sector of the ICU in Geneva between 2006 and 2009 resulted in exhaustion of the team members, who expressed their unwillingness to take care of these patients . In the beginning, the aim was to cohort the PLS to understand their specific needs and ensure their comfort including sleep, family visits and family needs in a confined area. The second goal was to acquire techniques and skills in this domain for future patients. The main reasons for the failure of the grouping of such patients included the burden of care, the difficult relationships with the family members as mentioned above, and the moral distress of caregivers regarding the meaning of care, as well as the uncertain prognoses and the slow evolution of PLS . The PLS were then re-distributed throughout the entire service in 2009. However, this experience confirmed that the care of these patients could not be similar to that of acutely ill patients. In order to ensure the continuity of PLS care; a referent nurse should be designated on a long-term basis. Kept out of the day/night shifts, he/she is a resource person for the patient and family members, and ensures the training of the healthcare team in PLS-specific management.
The years of expertise taught us the specific needs for the care of PLSs: multidisciplinary management, recovery of physical and psychological independence, early rehabilitation, sleep, relationships with family members, planning for the future, and the spiritual dimension .

Specific actions developed for the care of prolonged-stay patients
Identification of prolonged-stay patients and the checklist
On the seventh day of hospitalisation of the patient, a predefined professional (the ICU receptionist in our context) sticks a PLS signalling system and algorithm of care on the bedside monitor. This procedure reminds the caregivers to start the specific provision of care as defined in a checklist that lists the potential problems to discuss during the medical rounds. Furthermore, a PLS guideline is available on the ICU website.
Muscle tone is assessed weekly by physiotherapists using the Medical Research Council scale . Since skeletal muscle mass diminishes by 2 to 4% per day during critical illness and immobilisation, any measure to prevent its loss is important. Early activity is feasible even in ICU patients  and is a promising therapy to prevent or treat the neuromuscular complications of critical illness, although not enough data are available yet . Since physical recovery is a major concern after an ICU stay, such an approach may improve the patient’s quality of life after discharge .
A weekly consultation with a specialist in rehabilitation helps the physiotherapists select the types of authorised treatments adapted to the patient.
Under- or overfeeding of critical patients is associated with an increase in complications, costs and mortality . Insufficient caloric intake decreases the chances of returning home . PLSs need systematic monitoring of nutrition by a dietician, who determines their energy expenditure and helps adjust their intake.
Swallowing difficulty is common, especially after prolonged endotracheal intubation, and is underdiagnosed. There is a major threat of inhalation pneumonia in these patients. Although there is no evidence, small calibre enteral feeding tubes are to be preferred as soon as possible. A speech therapist helps by introducing rehabilitation treatment whenever possible. Future research should investigate the best way to avoid such ICU complications.
Cognitive disorders and psychological trauma
After ICU and hospital discharge, many PLSs experience neurocognitive disorders and long-term impairment [23, 24]. Therefore, neurocognitive assessment should be an integral part of care: as soon as patients are conscious (Glasgow coma scale above 12), they are assessed weekly with a modified Mini Mental State Examination (MMSE). This tool has been developed by our team to be applicable to intubated patients, with the collaboration of a neuropsychiatrist, and has been validated . The MMSE is used to anticipate, detect and monitor potential neurocognitive disorders. Early neurorehabilitative measures may be developed in the near future.
Scheduling daily activities
To decrease patient disorientation, a visual calendar and a visual daily activity schedule are placed on the bedside (fig. 2). This enables the patients to be informed and involved in the process of care.
Hospitalisation in the ICU can induce psychological distress in patients . Memories of the stay may be absent or fragmented. Many patients report delusional memories of people who tried to hurt or kill them, as well as dreams, nightmares and hallucinations. Between 14 and 41% of patients will develop symptoms of post-traumatic stress disorder (PTSD).
A diary can help reconstruct the ICU experience and has been shown to prevent PTSD . The patient’s relatives and caregivers write the ICU events in a notebook to allow the patient to recapture his/her history. It is given to the patient or their relatives upon ICU discharge.
The multidisciplinary conference
After a prolonged stay in the ICU, the objectives of care sometimes become unclear or disparate for the team. It is mandatory to hold a multidisciplinary conference where the referent nurse, the physician, the nurse in charge of the patient, as well as the external caregivers (speech therapist, surgeons, consulting physicians, physiotherapists, etc.) meet to discuss the management of the PLS. The purpose of such a conference is to redefine the short-, medium- and long-term therapeutic objectives. It aims to ensure consistent care. The conference should then be summarised in the patient’s medical and nursing charts. The therapeutic project is also communicated to the relatives. Communication with family members is no different from other aspects of critical care and requires training, interdisciplinary teamwork, and implementation of effective and flexible protocols to achieve the best possible outcome .
Preparing the patient’s discharge to the ward
PLSs become very dependent and require heavy nurse assistance. In the ICU, the nurse/patient ratio is 1/1–2. Moreover, a close relationship often binds the PLS to caregivers. The patients experience a real loss when discharged to the ward. Preparation is thus essential. The transfer of patients from the ICU to a medical unit can be a very challenging process .
Once the decision to transfer the patient is made, the ICU team organises an interview with the next caregiver team. Whenever possible, the patient is invited to visit the new department. This procedure provides the first human contact and serves to reduce patient apprehension. The focus is then applied to communication of the situation and ongoing problems (ventilator weaning, pain control, cognitive monitoring, motor rehabilitation, nutrition, social-family environment, sleep, etc.).
The PLS initiatives described are the result of 10 years of reflection, experience and research. The multidisciplinary group started a management framework, helped to develop the skills required for these patients and created new tools for their care. Because of the multimodal character of this experience, we have yet to demonstrate scientifically the benefit of such management. However, the project seems to make sense and future research may demonstrate the benefit of such an enterprise. Readmissions have already decreased and between 2014 and 2015 many former PLSs spontaneously gave updates to the team, and came back to meet their caregivers and to see the environment. Since these PLSs present problems that extend far beyond the duration of their stay in the ICU, the group wishes to offer a post-ICU consultation. This would allow us to gain knowledge about the patients’ outcome, and enhance the partnerships with the hospital caregivers post-ICU and possibly with general practitioners outside the hospital .
We are presently training the ICU team in massage techniques to decrease the anxiety and pain of patients, as well as to improve their sleep quality. The group aims to analyse the causes of poor sleep quality and propose strategies. This is the subject of our next research project in the Geneva ICU.
