Zusammenfassung
Ziel
Einen „Update” eines publizierten systematischen Reviews klinischer Studien zum Thema Geistheilung zu erstellen.
Design
Systematisches Review.
Quellen
Medline, Embase, Cochrane Library und eigene Unterlagen.
Studienauswahl
Klinische Studien jeder Art zum Thema Geistheilung, die zwischen 2000 und Dezember 2002 publiziert wurden.
Dataextraktion
Zu jeder inkludierten Studie wurden wesentliche Daten extrahiert und in narrativer Form zusammengefasst.
Ergebnisse
8 nicht-randomisierte und 9 randomisierte klinische Studien wurden aufgefunden. Die Mehrzahl der methodisch hochstehenden Studien stützen die These nicht, dass Geistheilung mit spezifischen Therapieeffekten assoziert ist. Die Ergebnisse von zwei Studien schließlich implizieren, dass Geistheilung mit unerwünschten Nebenwirkungen assoziiert sein kann.
Schlussfolgerung
Seit der Publikation unseres systematischen Reviews im Jahr 2000 sind zum Thema Geistheilung mehrere aussagekräftige Studien erschienen. Dieses neue Datenmaterial ist ingesamt weniger positiv und spricht nicht für die These, dass Geistheilung mit mehr als einem Plazebo-Effekt assoziiert ist.
Summary
Aim
To update our published systematic review of clinical trials of distant healing.
Design
Systematic review.
Data sources
Medline, Embase, Cochrane Library and personal files.
Study selection
Any type of clinical study of any type of distant healing published between 2000 and December 2002.
Data extraction
For each included study, essential data were extracted and summarised in narrative form.
Results
8 non-randomised and 9 randomised clinical trials were located. The majority of the rigorous trials do not to support the hypothesis that distant healing has specific therapeutic effects. The results of two studies furthermore suggest that distant healing can be associated with adverse effects.
Conclusion
Since the publication of our previous systematic review in 2000, several rigorous new studies have emerged. Collectively they shift the weight of the evidence against the notion that distant healing is more than a placebo.
