Determinants for receiving acupuncture for LBP and associated treatments: a prospective cohort study.

BACKGROUND: Acupuncture is a frequently used but controversial adjunct to the treatment of chronic low back pain (LBP). Acupuncture is now considered to be effective for chronic LBP and health care systems are pressured to make a decision whether or not acupuncture should be covered. It has been suggested that providing such services might reduce the use of other health care services. Therefore, we explored factors associated with acupuncture treatment for LBP and the relation of acupuncture with other health care services. METHODS: This is a post hoc analysis of a longitudinal prospective cohort study. General practitioners (GPs) recruited consecutive adult patients with LBP. Data on physical function, subjective mood and utilization of health care services was collected at the first consultation and at follow-up telephone interviews for a period of twelve months. RESULTS: A total of 179 (13 %) out of 1,345 patients received acupuncture treatment. The majority of those (59 %) had chronic LBP. Women and elderly patients were more likely to be given acupuncture. Additional determinants of acupuncture therapy were low functional capacity and chronicity of pain. Chronic (vs. acute) back pain OR 1.6 (CL 1.4-2.9) was the only significant disease-related factor associated with the treatment. The strongest predictors for receiving acupuncture were consultation with a GP who offers acupuncture OR 3.5 (CL 2.9-4.1) and consultation with a specialist OR 2.1 (CL 1.9-2.3). After adjustment for patient characteristics, acupuncture remained associated with higher consultation rates and an increased use of other health care services like physiotherapy. CONCLUSION: Receiving acupuncture for LBP depends mostly on the availability of the treatment. It is associated with increased use of other health services even after adjustment for patient characteristics. In our study, we found that receiving acupuncture does not offset the use of other health care resources. A significant proportion of patients who received did not meet the so far only known selection criterion (chonicity). Acupuncture therapy might be a reflection of helplessness in both patients and health care providers.

Evaluating the accuracy of a simple heuristic to identify serious causes of low back pain.

BACKGROUND: Among patients presenting with low back pain (LBP), GPs have to identify those with serious, treatable conditions. However, excluding these conditions in every patient with LPB is time consuming and of low yield. We have suggested that identifying those patients where these serious conditions need to be considered can be made more efficient through asking patient if they feel their LBP is new or unfamiliar in some way. OBJECTIVE: To evaluate the diagnostic validity of a simple heuristic based on the patient's view of the familiarity of LBP. METHODS: Cross-sectional diagnostic study with delayed-type reference standard, nested within a three-arm randomized trial of quality improvement for LBP. A total of 1378 patients presenting, with LBP, to one of 126 participating GPs were included. They were asked whether their LBP was familiar or not (index test). At 1 year, patients were interviewed with regard to relevant conditions that in hindsight might explain their LBP. Reviewers deciding on disease status (reference standard) were blinded to the results of the index test. RESULTS: Totally 1190 patients answered the index test question and were available for interview at 1 year. Only four of these had a serious cause of their LBP. Two of these were identified by the familiarity heuristic, resulting in low sensitivity. CONCLUSION: The number of diseased patients was too small to obtain a reliable estimate of sensitivity. Low prevalence of serious disease in primary care poses difficulties for diagnostic research. In hindsight we would question whether an RCT-setting emphasizing non-specific LBP is suitable for this kind of research. At present, the familiarity heuristic cannot be recommended for patients presenting with LBP.

[Long-term benefits of a postgraduate programme in clinical epidemiology. The study programme "clinical evaluation" of the University of Marburg].

In 1997 the first Clinical Epidemiology Programme in Germany was founded at the University of Marburg. This has been a part-time programme of six months' duration for young medical researchers interested in study planning, conduct and analysis. We report the results of focus group evaluations undertaken at the end of each programme which is held every year. We also surveyed former participants by phone to assess long-term effects of the programme. Overall, according to participants' feedback the programme has been a success. In particular, competences in study planning and critical appraisal were considered useful. However, participants reported difficulties implementing their newly gained knowledge and skills within their home departments. Postgraduate programmes of this kind catalyze the establishment of clinical research at German University Medical Centres.

[Last but not least--the German Network EbM has got its glossary on EbM terms].

Evidence-based medicine is not self-explaining. But due to the use of methodological, technical and statistical terms beginners might find it difficult to get access to EbM. To overcome this hurdle, a working group of practising physicians and methodologists have developed a glossary for the German Network Evidence-based Medicine covering the most important terms and providing explanations by giving practical examples. Access is also possible through www.ebm-netzwerk.de/glossar.htm. The present glossary is just a start, though. Over the coming years more terms will have to be added according to the needs and suggestions of our readership. We thus call on active participation of its users.

Feedback for general practice trainers: developing and testing a standardised instrument using the importance-quality-score method.

INTRODUCTION: Although general practice vocational training has been mandatory in Germany since 1993, a service philosophy still prevails. To help general practice trainers develop their identity and skills as trainers we developed and tested a standardised instrument. The questionnaire is to be filled in by registrars after their attachment to a given practice and handed to the trainer as personal feedback on the training provided. METHODS: Items were collected by asking experts in the field to name content that should be covered. The resulting items were reduced using the importance-quality method derived from health-related quality of life research. Reliability was tested by registrars rating their training twice 3 weeks apart. They also provided free text comments that were coded and analysed to establish criterion validity. RESULTS: A total of 121 items were collected. Eighty registrars provided importance and quality ratings to reduce these to 43 items. Test-re-test reliability and criterion validity were also established. CONCLUSION: The importance-quality method proved to be useful for item reduction according to the objective of the questionnaire. Instruments evaluating the quality of vocational training must be context-sensitive.

[How many standards can variety take?].

The recently published "Curriculum Evidence-based Medicine" of the German Network Evidence-based Medicine and the German Agency for Quality in Medicine has been criticised for shortcomings in teaching methods and the teaching process. In this article, authors of the curriculum provide a replique to the criticisms.

[A new measure. New studies require new criteria for critical appraisal].

Over the last ten years the quality of published clinical trials has improved considerably. Randomised controlled design, concealed allocation, blinding, clinically relevant outcomes, large sample sizes and almost complete follow-up are standard features of most trials. As a result, standard evidence-based medicine criteria can no longer be used to separate the "wheat from the chaff". Here, we discuss recent studies which reveal only marginal superiority of new treatments over well-established and effective therapies. Nowadays, readers of reports should be particularly aware of the definition of control therapies, of clinical relevance when results are statistically significant, of the external validity and whether a trial serves a pragmatic or explanatory purpose.

[Evidence-based medicine in 2025--what will remain?].

The reader is invited to attend a symposium on the long-term impact of Evidence-based Medicine (EBM) held in 2025. When EBM emerged for the first time, there had been great expectations, not all of which were fulfilled. Against the background of many vested interests evidence from clinical studies was not always welcome. Nor had EBM been able to abolish controversy and conflict within the health care system. But EBM had been associated with a substantial change of clinical mentality with practitioners becoming more cooperative, more self-critical and open for a scientific basis of their work. Although the reasoning of doctors has remained within a narrative framework, EBM has provided them with a critical tool for diagnosis, causal relations and intervention.
