[Transition from intensive care to palliative care : A retrospective analysis of 102 consultation requests]

The transition of patients from the intensive care unit (ICU) to the palliative care (PC) ward often implies changes including establishing a palliative concept. Adaptation of therapeutic goals can be challenging for medical staff, patients and relatives; however, descriptions of these transition trajectories are rare.

The aim of this retrospective study was to characterize the consultation requests of the ICU to the PC consultation team as well as the patients by a description of trajectories and interventions.

Retrospective analysis of all patients receiving intensive care at RWTH Aachen University Hospital in 2019 for whom a PC consultation was requested. The patient population transferred from the ICU to the PC ward was compared with the non-transferred population. In each case, the primary consultation was evaluated regarding the following factors: question, vigilance, length of time from consultation request to its performance, and primary focus of the question. The question focus was categorized into "symptom control", "counselling" and "transfer" (tick options). In addition, a free text field was available for further notes. Exploration of diagnoses was complemented by accessing the electronic health records.

A total of 102 consultation requests from the ICU to the PC ward were evaluated. The morbidity of patients was high, and most patients had at least one of the following diagnoses: pulmonary (62%), cardiovascular (61%), and/or neurological disease (55%). Of the patients 32 (31%) were transferred to the PC ward, among whom weakness (94%), fatigue (77%), anxiety (55%), pain (53%), and dyspnea (48%) were the most frequently noted symptoms. Of the transferred patients 5 (16%) could be discharged to home, nursing home, hospice or other. In total, 35 (34%) of all patients who were seen by palliative care specialists on ICUs in 2019 could be discharged alive. The most frequent reasons for nonadmission were lack of capacity of the PC ward (33%), dying while being on the waiting list (20%), and refusal by the patient (20%). Of the patients, 7 (26%) died within 48 h after they had been transferred to the PC ward. Performed consultation services "symptom control" (χ² = 10.17; p < 0.05) and "counselling" (χ² = 12.82; p < 0.001), which were requested by the intensive care physicians, showed a significant linkage with the respective intervention performed by the palliative care team. On the other hand, no statistically significant difference was found for requested and performed "transfer" of patients from ICUs to PC ward. Comparing the transferred versus non-transferred patient population, a significantly more frequent transfer of patients with malignant tumors (p = 0.00) was observed.

The need for palliative care support in the ICUs exceeded the admission capacity of the PC ward. Future studies should further examine palliative care models in intensive care medicine.
