[Austrian guideline for palliative sedation therapy (long version) : Results of a Delphi process of the Austrian Palliative Society (OPG)]. / Leitlinie zur Palliativen Sedierungstherapie (Langversion) : Ergebnisse eines Delphiprozesses der Österreichischen Palliativgesellschaft (OPG).

BACKGROUND: Palliative sedation therapy (PST) is an important and ethically accepted therapy in the care of selected palliative care patients with otherwise unbearable suffering from refractory distress. PST is increasingly used in end-of-life care. Austria does not have a standardized ethical guideline for this exceptional practice near end of life, but there is evidence that practice varies throughout the country. OBJECTIVE: The Austrian Palliative Society (OPG) nominated a multidisciplinary working group of 16 palliative care experts and ethicists who established the national guideline on the basis of recent review work with the aim to adhere to the Europeans Association of Palliative Care's (EAPC) framework on palliative sedation therapy respecting Austrians legal, structural and cultural background. METHODS: Consensus was achieved by a four-step sequential Delphi process. The Delphi-process was strictly orientated to the recently published EUROIMPACT-sedation-study-checklist and to the AGREE-2-tool. Additionally national stakeholders participated in the reflection of the results. RESULTS: As a result of a rigorous consensus process the long version of the Austrian National Palliative Sedation Guideline contains 112 statements within eleven domains and is supplemented by a philosophers excursus on suffering. CONCLUSIONS: By establishing a national guideline for palliative sedation therapy using the Delphi technique for consensus and stakeholder involvement the Austrian Palliative Society aims to ensure nationwide good practice of palliative sedation therapy. Screening for the practicability and efficacy of this guideline will be a future task.

Sedation at the end of life - a nation-wide study in palliative care units in Austria.

BACKGROUND: Sedation is used to an increasing extent in end-of-life care. Definitions and indications in this field are based on expert opinions and case series. Little is known about this practice at palliative care units in Austria. METHODS: Patients who died in Austrian palliative care units between June 2012 and June 2013 were identified. A predefined set of baseline characteristics and information on sedation during the last two weeks before death were obtained by reviewing the patients' charts. RESULTS: The data of 2414 patients from 23 palliative care units were available for analysis. Five hundred two (21 %) patients received sedation in the last two weeks preceding their death, 356 (71 %) received continuous sedation until death, and 119 (24 %) received intermittent sedation. The median duration of sedation was 48 h (IQR 10-72 h); 168 patients (34 %) were sedated for less than 24 h. Indications for sedation were delirium (51 %), existential distress (32 %), dyspnea (30 %), and pain (20 %). Midazolam was the most frequently used drug (79 %), followed by lorazepam (13 %), and haloperidol (10 %). Sedated patients were significantly younger (median age 67 years vs. 74 years, p ≤ 0.001, r = 0.22), suffered more often from an oncological disease (92 % vs. 82 %, p ≤ 0.001, φ = 0.107), and were hospitalized more frequently (94 % vs. 76 %, p ≤ 0.001, φ = 0.175). The median number of days between admission to a palliative care ward/mobile palliative care team and death did not differ significantly in sedated versus non-sedated patients (10 vs. 9 days; p = 0.491). CONCLUSION: This study provides insights into the practice of end-of-life sedation in Austria. Critical appraisal of these data will serve as a starting point for the development of nation-wide guidelines for palliative sedation in Austria.

Sedation indicated?-rethinking existential suffering: a narrative review.

BACKGROUND AND OBJECTIVE: The indication "existential suffering (ES)" for palliative sedation therapy is included in most frameworks for palliative sedation and has been controversially discussed for decades. The appellative character of ES demands rapid relief and sedation often appears to be the best or only solution. ES is still poorly understood and so often neglected by health care professionals due to a lack of consensus regarding assessment, definition and treatment in the international medical literature. Based on a selective review of the literature on ES we propose a different view on the underlying processes of ES and the resulting consequences on medical treatment. METHODS: A narrative review was performed after PubMed search using key terms related to ES and sedation, covering the period from 1950 to April 2023, additionally a selective search in specialist literature on Existential Analysis. Reverse and forward snowballing followed. The language of analyzed publications was restricted to English and German. KEY CONTENT AND FINDINGS: ES is a multidimensional experience that tends to turn into despair and ultimately into a wish to die due to perceived hopelessness and meaninglessness. Pharmacological treatment or sedation do not meet the holistic needs of existential sufferers. The risk of harmful effects by continuous deep sedation seems to be significantly increased for existentially suffering patients. Professional caregivers are burdened by the appellative character of ES, limited treatment options and perceived empathic distress. Without a holistic understanding of the human condition in palliative care, ES cannot be fundamentally alleviated, and existential sufferers have no opportunity to transform and thus mitigate their condition. The recognition of underlying causes of suffering-moods is facilitated by the comprehensive approach of Existential Analysis. CONCLUSIONS: The presented concept of Existential Analysis and the triad of ES are useful instruments for health care professionals to recognize and support underlying moods of existentially suffering patients. Further studies are required. Comprehensive training for professional caregivers on ES is essential to enable them to reflect on their own existential concerns and finiteness as well as those of patients. Continuous deep sedation for ES must remain the exception, equivalent to a last resort option.

[Paternalism and autonomy--no contradiction]. / Fürsorge und Autonomie--kein Widerspruch.

Patient autonomy became increasingly important during the last decades. It is often described to be an antagonist to medical paternalism. Like for patients with full decisional capacity, autonomy should also be protected for incapacitated patients. To enable this, the Austrian legislator recently regulated advance directives and durable powers of attorney. These tools should be combined with a process of communication with the patient's loved ones and consultation by a caring physician according to the integrative model. This can enhance and supplement the patient's autonomy. This article demonstrates surrogate decision making in theory and by the example of a case report.
