ABSTRACT
Background:
Clear
evidence of baseline response to homoeopathy in uncontrolled,
normal clinical practice is missing. German health insurance companies
launched so-called trial phases in which homeopathy could be evaluated
in real practice settings.
Research
Questions:
To
evaluate the overall effectiveness in general practice of homoeopathy
and to identify research needs as well as problems of evaluation
within pragmatic trials.
Methods
and Design:
Prospective
documentation of all patients insured with an insurance company
(Innungskrankenkasse) who are provided with free homoeopathy treatment.
The aim was to include about 1000 patients. All patients were
followed up from the beginning of treatment for 4 years. Doctors
provided data on each visit (diagnoses, treatment, change of symptoms),
patients filled in questionnaires at the beginning and twice a
year (complaints, current treatment, general health status as
measured by the MOS SF-36). Insurance data on work-days lost was
provided by the insurance company. We intended to collect data
on a matched control sample receiving conventional treatment.
Results:
About
750 patients treated with homoeopathy have been entered into the
study. Those were the patients for whom at least one component
of the documentation was available. The doctors´ rating
of the change of the main diagnosis showed improvement of 1 point
on a 7-point Likert Scale (>1 SD). This impression of effectiveness
is vindicated by the patient´s follow-up questionnaire:
About 38% of the patients rated the therapy as efficacious and
further 26% as partially efficacious. Quality of life as measured
by the MOS SF-36 improved in most dimensions highly significantly.
Despite good ratings of improvement, over 85% of the patients
did not show up for further treatment. This might be due to success
of treatment or as declining motivation. The intended control
group could not be sampled due to patients‘ preferences for homeopathy
or acupunture. The documentation of diseases and symptoms was
according to ICD-10. Individual symptoms return as well. Both
were either too general or too individually focused to form subgroups.
Conclusions:
Clinically
significant changes were observed. Even though a high number of
patients treated in real life practice were included some questions
remained unclear due to the nature of documentation in the study.
