EU PAS Register NumberEUPAS7082
Official titleSurvey on experiences with phytopharmaceuticals via an online based questionnaire
Study title acronymPhytoVIS
Study typeObservational study
Brief description of the studyThis study aims to collect data on application experiences of phytopharmaceuticals. The majority of phytopharmaceuticals in Germany are not covered by the statutory health insurance. Therefore GPs don't have the feasibility to prescribe herbal medicines nor to follow up the treatment. Furthermore the patients' compliance is hardly or not auditable. Data regarding reasons for applying pharmaceuticals, adverse effects or tolerance to herbal medicines are not systematically collected in Germany.
PhytoVIS was initiated in order to gain information on the effect experience of patients taking phytompharmaceuticals. The study is not designed to take into account specific subgroups, but to collect data of all natural persons who have been taking herbal medicine during the previous eight weeks on the date of questioning. Amoung others the 'Clinical Global Impression Scale - Efficacy' (GGI-E) questionnaire will be used. Nota bene this study cannot deliver specific proofs on the effectiveness of different drugs. Rather PhytoVIS takes into account the overall effect experience during the therapeutic intervention. Thereby other factors and the course of disease play a role.
Concerning adverse events no linkage to causal relationships is possible. Yet all adverse events will be documented and allow a more detailed evaluation. In addition to that data gained on children, pregnant women, and elderly people are valuable, since there are hardly any data available on these subgroups.
A secondary endpoint of PhytoVIS is the collection of information on the way of purchase of the medicine as well as on way of recommendation, which will add to the knowledge on health services research.
20 000 data sets will be collected via the online database 'PhytoVIS', that was successfully tested and validated in a pilot phase with 2000 data sets. Natural persons will be questioned at pharmacies.

15. Data analysis plan
Please provide a brief summary of the analysis method
For ascertainment of the patients' opinions and experiences on effectiveness and tolerance of phytopharmaca the validated scale of the questionnaire 'Clinical Global Impression Scale - Efficacy' (CGI-E) is utilised. The CGI-E consists of a matrix with 16 fields that builds up the relation between adverse effects and therapeutic effects. The scores range from four (maximum) to 0,25 (minimum). An index of efficacy is calculated, where any values > 1.00 correspond to a predominant therapeutic effect, the value 1.00 means that the effects cancel each other out, any value < 1.00 reflects that adverse effects predominate.
The secondary endpoint of the study, health service research on the phytopharmaceuticals' purchase and recommendation are inquired by questions about (1) the source of recommendations, e.g. pharmacist, doctor, family, friends, advertisement etc. and (2) the site of purchase, e.g. pharmacy, drug store, supermarket, organic food store.
