Frau Doktor, wie lange noch? Die Palliative Performance Scale (PPS) als Hilfsmittel zur Einschätzung der Lebenszeit von PalliativpatientInnen – Validierung einer deutschen Version
- 34 Downloads
Zusammenfassung
Die Palliative Performance Scale (PPS) wird in ihrer englischen Originalversion seit etwa zwei Jahrzehnten verwendet, um das Funktionsniveau von PalliativpatientInnen mithilfe von anamnestisch erhebbaren bzw. beobachtbaren Parametern zu beschreiben. Daraus kann die noch zu erwartende Lebenszeit abgeschätzt werden: je höher das Funktionsniveau desto länger die zu erwartende Lebenszeit. Sowohl lebensbedrohlich Erkrankte wie auch ihre Angehörigen und Behandelnden haben ein Interesse die verbleibende Lebenszeit einschätzen zu können, um entsprechende Planungen vornehmen zu können. Bisher lag noch keine offizielle deutsche Übersetzung der PPS vor. Anhand von 394 PatientInnen eines palliativen Konsiliardienstes wurden die Funktionsniveaus entsprechend einer deutschen Version der PPS mit der Überlebenszeit korreliert, Kaplan-Meier-Kurven erstellt und auf Unterschiede geprüft. Es sollte die Hypothese geprüft werden, ob auch in der deutschen Version der PPS ein höheres Funktionsniveau mit längerem Überleben korreliert. In der untersuchten Population wurden klar Unterschiede des Überlebens entsprechend den einzelnen PPS-Kategorien dargestellt. Die PPS ist in der nun vorliegenden deutschen Version ein geeignetes und mögliches Hilfsmittel, um die Überlebenszeit von PalliativpatientInnen allein auf der Basis von klinischen Informationen einzuschätzen.

Summary
The original English version of the palliative performance scale (PPS) has been used for two decades to describe the functional status of palliative patients. Based on clinical parameters PPS helps to estimate the survival time of palliative patients: the higher the functional status the longer the survival. This is interesting for patients, their family caregivers and health care professionals in order to plan for care. Until now there has not been published an official German version of the PPS.
The functional status via a German version of the PPS of 394 patients of a palliative consulting team and their survival times were analyzed. Kaplan-Meier-curves were drawn and tested for differences. The hypothesis was tested if functional status using the German version of the PPS and survival are correlated. In this population differences in survival could clearly be shown for any category of PPS.
This German version of the PPS is a useful and possible tool to estimate survival time of palliative patients using just clinical information.
