Clinical Course after End-of-Life Decisions on a Neurosurgical Ward: Much to Learn and Improve.

Background:  End-of-life (EoL) decisions are routine in neurosurgical care due to frequent devastating and life-threatening diagnoses. Advance directives, discussions with patients' relatives, and evaluation of the alleged will of the patient play an increasing important role in clinical decision-making. Institutional standards, ethical values, different ethnical backgrounds, and individual physician's experiences influence clinical judgments and decisions. We hypothesize that the implementation of palliative care in neurosurgical wards needs optimization. The aim of this study is to identify possible sources of error and to share our experiences.

Methods:  This is a retrospective observational analysis. One hundred and sixty-eight patients who died on a regular neurosurgical ward between 2014 and 2019 were included. Medical reports were analyzed in detail. A differentiation between consistent and nonconsistent palliation was made, with consistent palliative care consisting of discontinuation of medication that was no longer indicated, administration of medication for symptom control, and consequent discontinuation of nutrition and fluid substitution that went beyond satisfying hunger or thirst.

Results:  EoL decisions were made in 127 (84.1%) of all 168 cases; 100 patients were included in our analysis. Of these patients, only 24 had an advance directive, and the relatives were included in the communication about the therapy goals in 71 cases. Discontinuation of medication that is not for symptom control was performed in 63 patients, food withdrawal in 66 patients, and fluid substitution that went beyond the quenching of thirst was withdrawn in 27 patients. Thus, consistent palliative care was realized in 25% of all patients. The mean duration from the EoL decision until death was 2.1 days (range: 0-20 days). If a consistent palliative care was carried out, patients survived significantly shorter (nonconsistent palliative care: 2.4 days; range: 0-10 days vs. consistent palliative care: 1.2 days; range: 0-4 days; p = 0.008).

Conclusions:  The therapy goal should be thoroughly considered and determined at an early stage. If an EoL decision is reached, consistent palliative care should be carried out in order to limit suffering of moribund patients.
