3.  A retrospective cost-analysis of additional homeopathic treatment in Germany: Long-term economic outcomes 
PLoS ONE  2017;12(9):e0182897.
Objectives
This study aimed to provide a long-term cost comparison of patients using additional homeopathic treatment (homeopathy group) with patients using usual care (control group) over an observation period of 33 months.
Methods
Health claims data from a large statutory health insurance company were analysed from both the societal perspective (primary outcome) and from the statutory health insurance perspective (secondary outcome). To compare costs between patient groups, homeopathy and control patients were matched in a 1:1 ratio using propensity scores. Predictor variables for the propensity scores included health care costs and both medical and demographic variables. Health care costs were analysed using an analysis of covariance, adjusted for baseline costs, between groups both across diagnoses and for specific diagnoses over a period of 33 months. Specific diagnoses included depression, migraine, allergic rhinitis, asthma, atopic dermatitis, and headache.
Results
Data from 21,939 patients in the homeopathy group (67.4% females) and 21,861 patients in the control group (67.2% females) were analysed. Health care costs over the 33 months were 12,414 EUR [95% CI 12,022–12,805] in the homeopathy group and 10,428 EUR [95% CI 10,036–10,820] in the control group (p<0.0001). The largest cost differences were attributed to productivity losses (homeopathy: EUR 6,289 [6,118–6,460]; control: EUR 5,498 [5,326–5,670], p<0.0001) and outpatient costs (homeopathy: EUR 1,794 [1,770–1,818]; control: EUR 1,438 [1,414–1,462], p<0.0001). Although the costs of the two groups converged over time, cost differences remained over the full 33 months. For all diagnoses, homeopathy patients generated higher costs than control patients.
Conclusion
The analysis showed that even when following-up over 33 months, there were still cost differences between groups, with higher costs in the homeopathy group.

4.  Women's reasons for participation in a clinical trial for menstrual pain: a qualitative study 
BMJ Open  2016;6(12):e012592.
Objectives
The aim of the study was to explore women's motivations for participating in a clinical trial and to evaluate how financial compensation impacts women's explanations for participation.
Design, setting and participants
Semistructured interviews were conducted face to face or by telephone with 25 of 220 women who participated in a pragmatic randomised trial for app-administered self-care acupressure for dysmenorrhoea (AKUD). Of these 25 women, 10 had entered AKUD knowing they would receive a financial compensation of €30. A purposive sampling strategy was used.
Results
Women had a long history of seeking help and were unsatisfied with the options available, namely painkillers and oral contraceptives. While interviewees were open to painkillers, they were uneasy about taking them on a monthly basis. The AKUD trial offered the possibility to find an alternative solution. A second reason for participation was the desire to add a new treatment to routine medical care, for which the interviewees considered randomised trials a prerequisite. The financial incentive was a subsidiary motivation in the interviewees' narratives.
Conclusions
Our results contribute to the ongoing discussion of the impact of financial compensation on research participants' assessment of risk. The interviewed women considered all research participants able to make their own choices regarding trial participation, even in the face of financial compensation or payment of study participants. Furthermore, the importance of clinical trials providing new treatments that could change medical practice might be an overlooked reason for trial participation and could be used in future recruitment strategies.

5.  A consultation training program for physicians for communication about complementary medicine with breast cancer patients: a prospective, multi-center, cluster-randomized, mixed-method pilot study 
BMC Cancer  2016;16:843.
Background
The aim was to develop and evaluate a training program for physicians for communicating with breast cancer patients about complementary medicine (CM).
Methods
In a cluster-randomized pilot trial eight breast cancer centers (two physicians per center) were randomized to either a complementary communication training program (9 h e-learning + 20 h on-site skills training) or to a control group without training. Each physician was asked to consult ten patients for whom he or she is not the physician in charge. We used mixed methods: Quantitative outcomes included physicians’ assessments (empathy, complexity of consultation, knowledge transfer) and patients’ assessments (satisfaction, empathy, knowledge transfer). For qualitative analyses, 15 (eight in the training and seven in the control group) videotaped consultations were analyzed based on grounded theory, and separate focus groups with the physicians of both groups were conducted.
Results
A total of 137 patients were included. Although cluster-randomized, physicians in the two groups differed. Those in the training group were younger (33.4 ± 8.9 vs. 40.0 ± 8.5 years) and had less work experience (5.4 ± 8.9 vs. 11.1 ± 7.4 years). Patient satisfaction with the CM consultation was relatively high on a scale from 0 to 24 and was comparable in the two groups (training group: 19.4 ± 4.6; control group 20.5 ± 4.1). The qualitative findings showed that physicians structured majority of consultations as taught during the training. Comparing only the younger and less CM experienced physicians, those trained in CM communication felt more confident discussing CM-related topics than those without training.
Conclusion
A CM communication-training program might be especially beneficial for physicians with less consulting experience when communicating about CM-related issues. A larger trial using more suitable quantitative outcomes needs to confirm this.

6.  How Do Patients with Chronic Neck Pain Experience the Effects of Qigong and Exercise Therapy? A Qualitative Interview Study 
Background. The high prevalence of chronic neck pain in high income countries impacts quality of life and the social and work-related activities of those afflicted. We aimed to understand how mind-body therapies and exercise therapy may influence the experience of pain among patients with chronic neck pain. Methods. This qualitative interview study investigated how patients with chronic neck pain experienced the effects of exercise or qigong therapy at two time points: during an intervention at three months and after the intervention at six months. Interviews were analysed thematically across interviews and within person-cases. Based on other qualitative studies, a sample size of 20 participants was deemed appropriate. Results. The sample (n = 20) consisted of 16 women and four men (age range: 29 to 59). Patients' experiences differed according to the therapies' philosophies. Exercise therapy group interviewees described a focus on correct posture and muscle tension release. Qigong group interviewees discussed calming and relaxing effects. Maintaining regular exercise was easier to achieve with exercise therapy. Conclusions. The findings of this study may help health care providers when counselling chronic pain patients on self-help interventions by informing them of different bodily and emotional experiences of mind-body interventions compared to exercise therapy.

7.  Unanticipated Insights into Biomedicine from the Study of Acupuncture 
Abstract
Research into acupuncture has had ripple effects beyond the field of acupuncture. This paper identifies five exemplars to illustrate that there is tangible evidence of the way insights gleaned from acupuncture research have informed biomedical research, practice, or policy. The first exemplar documents how early research into acupuncture analgesia has expanded into neuroimaging research, broadening physiologic understanding and treatment of chronic pain. The second describes how the acupuncture needle has become a tool to enhance biomedical knowledge of connective tissue. The third exemplar, which illustrates use of a modified acupuncture needle as a sham device, focuses on emergent understanding of placebo effects and, in turn, on insights into therapeutic encounters in treatments unrelated to acupuncture. The fourth exemplar documents that two medical devices now in widespread use were inspired by acupuncture: transcutaneous electrical nerve stimulators for pain control and antinausea wrist bands. The final exemplar describes how pragmatic clinical trial designs applied in acupuncture research have informed current general interest in comparative effectiveness research. In conclusion, these exemplars of unanticipated outcomes of acupuncture research comprise an additional rationale for continued support of basic and clinical research evaluating acupuncture and other under-researched therapies.

9.  Sustained Effects of Acupuncture Stimulation Investigated with Centrality Mapping Analysis 
Acupuncture can have instant and sustained effects, however, its mechanisms of action are still unclear. Here, we investigated the sustained effect of acupuncture by evaluating centrality changes in resting-state functional magnetic resonance imaging after manually stimulating the acupuncture point ST36 at the lower leg or two control point locations (CP1 same dermatome, CP2 different dermatome). Data from a previously published experiment evaluating instant BOLD effects and S2-seed-based resting state connectivity was re-analyzed using eigenvector centrality mapping and degree centrality mapping. These data-driven methods might add new insights into sustained acupuncture effects on both global and local inter-region connectivity (centrality) by evaluating the summary of connections of every voxel. We found higher centrality in parahippocampal gyrus and middle temporal gyrus after ST36 stimulation in comparison to the two control points. These regions are positively correlated to major hubs of the default mode network, which might be the primary network affected by chronic pain. The stronger integration of both regions within the whole-brain connectome after stimulation of ST36 might be a potential contributor to pain modulation by acupuncture. These findings highlight centrality mapping as a valuable analysis for future imaging studies investigating clinically relevant outcomes associated with physiological response to acupuncture stimulation.

10.  What Can Comparative Effectiveness Research Contribute to Integrative Health in International Perspective? 
Abstract
The interest in Comparative Effectiveness Research (CER) in the international community is growing. A panel titled “What Can Comparative Effectiveness Research Contribute to Integrative Health in International Perspective?” took place at the 3rd International Research Congress on Integrative Medicine and Health in Portland, Oregon, in 2012. The presentations at this panel highlighted different perspectives on CER, including the funders' and the stakeholders' perspectives from the United States, as well as experiences with economic evaluations from Australia and pragmatic trials in Europe. The funders' perspective emphasized the need for innovation and controlling costs in large-scale studies. The stakeholder's perspective stressed the need to gather the input of stakeholders in shaping the framework for more informative, more decision-maker-driven research. Several examples of cost-effectiveness analyses were offered from Australia. The importance of balancing rigor and pragmatism was also discussed in a presentation of the efficacy–effectiveness continuum. A wide-ranging discussion explored additional questions concerning the translation of evidence into practice; the effect of pragmatic trials on funding or policy; evidentiary distinctions between and among pragmatic trials and traditional randomized clinical trials; and the multiple roles of stakeholders, particularly in generating new information and knowledge. The presentations and discussions showed that more development of methods is needed. This includes developments on study design and statistical approaches, as well as methods for stakeholder involvement and mechanisms to bring these results into practice.

11.  Can Additional Homeopathic Treatment Save Costs? A Retrospective Cost-Analysis Based on 44500 Insured Persons 
PLoS ONE  2015;10(7):e0134657.
Objectives
The aim of this study was to compare the health care costs for patients using additional homeopathic treatment (homeopathy group) with the costs for those receiving usual care (control group).
Methods
Cost data provided by a large German statutory health insurance company were retrospectively analysed from the societal perspective (primary outcome) and from the statutory health insurance perspective. Patients in both groups were matched using a propensity score matching procedure based on socio-demographic variables as well as costs, number of hospital stays and sick leave days in the previous 12 months. Total cumulative costs over 18 months were compared between the groups with an analysis of covariance (adjusted for baseline costs) across diagnoses and for six specific diagnoses (depression, migraine, allergic rhinitis, asthma, atopic dermatitis, and headache).
Results
Data from 44,550 patients (67.3% females) were available for analysis. From the societal perspective, total costs after 18 months were higher in the homeopathy group (adj. mean: EUR 7,207.72 [95% CI 7,001.14–7,414.29]) than in the control group (EUR 5,857.56 [5,650.98–6,064.13]; p<0.0001) with the largest differences between groups for productivity loss (homeopathy EUR 3,698.00 [3,586.48–3,809.53] vs. control EUR 3,092.84 [2,981.31–3,204.37]) and outpatient care costs (homeopathy EUR 1,088.25 [1,073.90–1,102.59] vs. control EUR 867.87 [853.52–882.21]). Group differences decreased over time. For all diagnoses, costs were higher in the homeopathy group than in the control group, although this difference was not always statistically significant.
Conclusion
Compared with usual care, additional homeopathic treatment was associated with significantly higher costs. These analyses did not confirm previously observed cost savings resulting from the use of homeopathy in the health care system.

12.  MERGING conventional and complementary medicine in a clinic department – a theoretical model and practical recommendations 
Background
Today, the increasing demand for complementary medicine encourages health care providers to adapt and create integrative medicine departments or services within clinics. However, because of their differing philosophies, historical development, and settings, merging the partners (conventional and complementary medicine) is often difficult.
It is necessary to understand the similarities and differences in both cultures to support a successful and sustainable integration. The aim of this project was to develop a theoretical model and practical steps that are based on theories from mergers in business to facilitate the implementation of an integrative medicine department.
Methods
Based on a literature search and expert discussions, the cultures were described and model domains were developed. These were applied to two case studies to develop the final model. Furthermore, a checklist with practical steps was devised.
Results
Conventional medicine and complementary medicine have developed different corporate cultures. The final model, which should help to foster integration by bridging between these cultures, is based on four overall aspects: culture, strategy, organizational tools and outcomes. Each culture is represented by three dimensions in the model: corporate philosophy (core and identity of the medicine and the clinic), patient (all characteristics of the professional team’s contact with the patient), and professional team (the characteristics of the interactions within the professional team).
Conclusion
Overall, corporate culture differs between conventional and complementary medicine; when planning the implementation of an integrative medicine department, the developed model and the checklist can support better integration.

13.  Using the framework of corporate culture in “mergers” to support the development of a cultural basis for integrative medicine – guidance for building an integrative medicine department or service 
Background
An increasing number of clinics offer complementary or integrative medicine services; however, clear guidance about how complementary medicine could be successfully and efficiently integrated into conventional health care settings is still lacking. Combining conventional and complementary medicine into integrative medicine can be regarded as a kind of merger. In a merger, two or more organizations − usually companies − are combined into one in order to strengthen the companies financially and strategically. The corporate culture of both merger partners has an important influence on the integration.
Purpose
The aim of this project was to transfer the concept of corporate culture in mergers to the merging of two medical systems.
Methods
A two-step approach (literature analyses and expert consensus procedure) was used to develop practical guidance for the development of a cultural basis for integrative medicine, based on the framework of corporate culture in “mergers,” which could be used to build an integrative medicine department or integrative medicine service.
Results
Results include recommendations for general strategic dimensions (definition of the medical model, motivation for integration, clarification of the available resources, development of the integration team, and development of a communication strategy), and recommendations to overcome cultural differences (the clinic environment, the professional language, the professional image, and the implementation of evidence-based medicine).
Conclusion
The framework of mergers in corporate culture provides an understanding of the difficulties involved in integrative medicine projects. The specific recommendations provide a good basis for more efficient implementation.

14.  Differential cerebral response to somatosensory stimulation of an acupuncture point vs. two non-acupuncture points measured with EEG and fMRI 
Acupuncture can be regarded as a complex somatosensory stimulation. Here, we evaluate whether the point locations chosen for a somatosensory stimulation with acupuncture needles differently change the brain activity in healthy volunteers. We used EEG, event-related fMRI, and resting-state functional connectivity fMRI to assess neural responses to standardized needle stimulation of the acupuncture point ST36 (lower leg) and two control point locations (CP1 same dermatome, CP2 different dermatome). Cerebral responses were expected to differ for stimulation in two different dermatomes (CP2 different from ST36 and CP1), or stimulation at the acupuncture point vs. the control points. For EEG, mu rhythm power increased for ST36 compared to CP1 or CP2, but not when comparing the two control points. The fMRI analysis found more pronounced insula and S2 (secondary somatosensory cortex) activation, as well as precuneus deactivation during ST36 stimulation. The S2 seed-based functional connectivity analysis revealed increased connectivity to right precuneus for both comparisons, ST36 vs. CP1 and ST36 vs. CP2, however in different regions. Our results suggest that stimulation at acupuncture points may modulate somatosensory and saliency processing regions more readily than stimulation at non-acupuncture point locations. Also, our findings suggest potential modulation of pain perception due to acupuncture stimulation.

15.  Effectiveness of app-based relaxation for patients with chronic low back pain (Relaxback) and chronic neck pain (Relaxneck): study protocol for two randomized pragmatic trials 
Trials  2014;15:490.
Background
Chronic low back pain (LBP) and neck pain (NP) are highly prevalent conditions resulting in high economic costs. Treatment guidelines recommend relaxation techniques, such as progressive muscle relaxation, as adjuvant therapies. Self-care interventions could have the potential to reduce costs in the health care system, but their effectiveness, especially in a usual care setting, is unclear. The aim of these two pragmatic randomized studies is to evaluate whether an additional app-delivered relaxation is more effective in the reduction of chronic LBP or NP than usual care alone.
Methods/design
Each pragmatic randomized two-armed study aims to include a total of 220 patients aged 18 to 65 years with chronic (>12 weeks) LBP or NP and an average pain intensity of ≥ 4 on a numeric rating scale (NRS) in the 7 days before recruitment. The participants will be randomized into an intervention and a usual care group. The intervention group will be instructed to practice one of these 3 relaxation techniques on at least 5 days/week for 15 minutes/day over a period of 6 months starting on the day of randomization: autogenic training, mindfulness meditation, or guided imagery. Instructions and exercises will be provided using a smartphone app, baseline information will be collected using paper and pencil. Follow-up information (daily, weekly, and after 3 and 6 months) will be collected using electronic diaries and questionnaires included in the app.
The primary outcome measure will be the mean LBP or NP intensity during the first 3 months of intervention based on daily pain intensity measurements on a NRS (0 = no pain, 10 = worst possible pain). The secondary outcome parameters will include the mean pain intensity during the first 6 months after randomization based on daily measurements, the mean pain intensity measured weekly as the average pain intensity of the previous 7 days over 3 and 6 months, pain acceptance, ‘LBP- and NP-related’ stress, sick leave days, pain medication intake, adherence, suspected adverse reaction, and serious adverse events.
Discussion
The designed studies reflect a usual self-care setting and will provide evidence on a pragmatic self-care intervention that is easy to combine with care provided by medical professionals.

16.  Internal health locus of control in users of complementary and alternative medicine: a cross-sectional survey 
Background
Complementary and alternative medicine (CAM) is widely used in Germany, with some treatments eligible for health insurance reimbursements. CAM encourages patients to play an active role in their healing process. The belief that a person’s own behavior influences health is assessed as the internal health locus of control (IHLOC). Studies on the association between IHLOC and CAM use yield inconsistent results. Using various indicators of CAM use, we evaluated whether there were differences in IHLOC between different groups of CAM users.
Methods
A cross-sectional online survey was conducted. IHLOC was compared between participants with high and low appraisal of CAM, between participants who used different types of medications (none, CAM, conventional, both), and who consulted with different health care professionals (none, CAM, conventional, both). Independent samples t-tests and ANOVAs were conducted for the total group and for subgroups of chronically ill and healthy participants. Post-hoc, we conducted a multivariate linear regression evaluating which indicators of CAM use or other characteristics showed the strongest association with IHLOC.
Results
A total of 1,054 undergraduate students completed the survey. Participants with high CAM appraisal showed higher IHLOC than those with low CAM appraisal, regardless of whether they were chronically ill (p < .001). Participants without chronic conditions showed higher IHLOC when only using CAM medications than when using either conventional medications alone or both conventional and CAM medications (p < .05). All participants showed higher IHLOC when visiting only CAM practitioners than when visiting either only conventional or both conventional and CAM practitioners (p < .05). CAM appraisal was associated the strongest with IHLOC in the linear regression model.
Conclusions
Generally, participants using CAM more or exclusively, and participants with higher appraisal of CAM showed higher IHLOC than those with less CAM use or lower CAM appraisal. Because of the cross-sectional design, it is not possible to determine whether differences in IHLOC are reasons for or consequences of CAM use. Research using a longitudinal design is needed. The sample, though more representative than most student samples, might not represent the general population. Studies evaluating clinical populations might add to the findings.

17.  Perceived outcomes of spiritual healing and explanations - a qualitative study on the perspectives of German healers and their clients 
Background
Limited research has been conducted on contemporary spiritual healing in European countries. The aim of this article is to report how German healers and their clients experienced and perceived the outcomes of spiritual healing and which explanations they use to describe the perceived effects.
Methods
Semistructured interviews and participatory observation was used to collect data from spiritual healers and their clients. Analyses were based on the methodological concept of directed qualitative content analysis. Data was analyzed using MAXQDA software, discussed and reviewed by a multidisciplinary research team consisting of medical anthropologists, medical doctors and a religious studies scholar.
Results
In total 15 healers and 16 clients participated in this study, 24 interviews with healers, 20 interviews with clients and 8 participatory observations were analyzed. Healers and clients reported outcomes as positively perceived body sensations, increased well-being, positive emotions and symptomatic relief of medical complaints. Clients often described changes in their self-concepts and adapted life values. Explanations for perceived effects included connecting with transcendent sources, construction of meaning, as a result of the client-healer relationship, and as empowerment to make changes. Because the interviewed clients were recruited by the healers, a selection bias towards positive healing experiences is possible.
Conclusion
We hypothesize that concepts of meaning construction, resource activation and the utilization of the clients’ expectations help to explain the data. Grounded in the emic perspective, we propose to use the following outcomes for further prospective studies: positive body sensations, changes of self-concepts and values, changes of medical symptoms and complaints. From the etic perspective, physical, emotional, social and spiritual wellbeing, sense of coherence, meaningfulness of life, empowerment, resource activation, change and symptom control should be further explored as potential outcomes.

18.  Effectiveness guidance document (EGD) for Chinese medicine trials: a consensus document 
Trials  2014;15:169.
Background
There is a need for more Comparative Effectiveness Research (CER) on Chinese medicine (CM) to inform clinical and policy decision-making. This document aims to provide consensus advice for the design of CER trials on CM for researchers. It broadly aims to ensure more adequate design and optimal use of resources in generating evidence for CM to inform stakeholder decision-making.
Methods
The Effectiveness Guidance Document (EGD) development was based on multiple consensus procedures (survey, written Delphi rounds, interactive consensus workshop, international expert review). To balance aspects of internal and external validity, multiple stakeholders, including patients, clinicians, researchers and payers were involved in creating this document.
Results
Recommendations were developed for “using available data” and “future clinical studies”. The recommendations for future trials focus on randomized trials and cover the following areas: designing CER studies, treatments, expertise and setting, outcomes, study design and statistical analyses, economic evaluation, and publication.
Conclusion
The present EGD provides the first systematic methodological guidance for future CER trials on CM and can be applied to single or multi-component treatments. While CONSORT statements provide guidelines for reporting studies, EGDs provide recommendations for the design of future studies and can contribute to a more strategic use of limited research resources, as well as greater consistency in trial design.

19.  Perceived outcomes of music therapy with Body Tambura in end of life care – a qualitative pilot study 
BMC Palliative Care  2014;13:18.
Background
In recent years, music therapy is increasingly used in palliative care. The aim of this pilot study was to record and describe the subjective experiences of patients and their relatives undergoing music therapy with a Body Tambura in a German hospice and to develop hypotheses for future studies.
Methods
In a qualitative interview pilot study, data collection and analyses were performed according to the methodological framework of grounded theory. We included German-speaking patients, or relatives of patients, receiving end of life care in an inpatient hospice setting.
Results
11 persons consisting of 8 patients (age range 51–82 years, 4 male and 4 female) and 3 relatives were treated and interviewed. All patients suffered from cancer in an advanced stage. The most often described subjective experiences were a relaxing and calming effect, sensations that the body feels lighter, and the generation of relaxing images and visualizations. Family members enjoyed listening to the music and felt more connected with the sick family member.
Conclusion
Patient reported beneficial aspects. The small sample size could be seen as a limitation. Assessment instruments measuring relaxation, stress, quality of life and should be included in future quantitative studies.

20.  A randomised multicentre trial of acupuncture in patients with seasonal allergic rhinitis – trial intervention including physician and treatment characteristics 
Background
In a large randomised trial in patients with seasonal allergic rhinitis (SAR), acupuncture was superior compared to sham acupuncture and rescue medication. The aim of this paper is to describe the characteristics of the trial’s participating physicians and to describe the trial intervention in accordance with the STRICTA (Standards for Reporting Interventions in Controlled Trials of Acupuncture) guidelines, to make details of the trial intervention more transparent to researchers and physicians.
Methods
ACUSAR (ACUpuncture in Seasonal Allergic Rhinitis) was a three-armed, randomised, controlled multicentre trial. 422 SAR patients were randomised to semi-standardised acupuncture plus rescue medication (RM, cetirizine), sham acupuncture plus RM or RM alone. We sent a questionnaire to trial physicians in order to evaluate their characteristics regarding their education about and experience in providing acupuncture. During the trial, acupuncturists were asked to diagnose all of their patients according to Chinese Medicine (CM) as a basis for the semi-standardised, individualized intervention in the acupuncture group. Every acupuncture point used in this trial had to be documented after each session
Results
Acupuncture was administered in outpatient clinics by 46 (mean age 47 ± 10 years; 24 female/ 22 male) conventionally-trained medical doctors (67% with postgraduate specialization such as internal or family medicine) with additional extensive acupuncture training (median 500 hours (1st quartile 350, 3rd quartile 1000 hours with 73% presenting a B-diploma in acupuncture training (350 hours)) and experience (mean 14 years in practice). The most reported traditional CM diagnosis was ‘wind-cold invading the lung’ (37%) and ‘wind-heat invading the lung’ (37%), followed by ‘lung and spleen qi deficiency’ (9%). The total number of needles used was higher in the acupuncture group compared to the sham acupuncture group (15.7 ± 2.5 vs. 10.0 ± 1.6).
Conclusions
The trial interventions were provided by well educated and experienced acupuncturists. The different number of needles in both intervention groups could be possibly a reason for the better clinical effect in SAR patients. For future trials it might be more appropriate to ensure that acupuncture and sham acupuncture groups should each be treated by a similar number of needles.

21.  Influence of Control Group on Effect Size in Trials of Acupuncture for Chronic Pain: A Secondary Analysis of an Individual Patient Data Meta-Analysis 
PLoS ONE  2014;9(4):e93739.
Background
In a recent individual patient data meta-analysis, acupuncture was found to be superior to both sham and non-sham controls in patients with chronic pain. In this paper we identify variations in types of sham and non-sham controls used and analyze their impact on the effect size of acupuncture.
Methods
Based on literature searches of acupuncture trials involving patients with headache and migraine, osteoarthritis, and back, neck and shoulder pain, 29 trials met inclusion criteria, 20 involving sham controls (n = 5,230) and 18 non-sham controls (n = 14,597). For sham controls, we analysed non-needle sham, penetrating sham needles and non-penetrating sham needles. For non-sham controls, we analysed non-specified routine care and protocol-guided care. Using meta-regression we explored impact of choice of control on effect of acupuncture.
Findings
Acupuncture was significantly superior to all categories of control group. For trials that used penetrating needles for sham control, acupuncture had smaller effect sizes than for trials with non-penetrating sham or sham control without needles. The difference in effect size was −0.45 (95% C.I. −0.78, −0.12; p = 0.007), or −0.19 (95% C.I. −0.39, 0.01; p = 0.058) after exclusion of outlying studies showing very large effects of acupuncture. In trials with non-sham controls, larger effect sizes associated with acupuncture vs. non-specified routine care than vs. protocol-guided care. Although the difference in effect size was large (0.26), it was not significant with a wide confidence interval (95% C.I. −0.05, 0.57, p = 0.1).
Conclusion
Acupuncture is significantly superior to control irrespective of the subtype of control. While the choice of control should be driven by the study question, our findings can help inform study design in acupuncture, particularly with respect to sample size. Penetrating needles appear to have important physiologic activity. We recommend that this type of sham be avoided.

22.  Use of complementary and alternative medicine by older adults – a cross-sectional survey 
BMC Geriatrics  2014;14:38.
Background
Very little is known about complementary and alternative medicine (CAM) use by older adults in Germany. The aim of this study was to investigate the use of CAM and other health promoting substances (e.g., herbal teas) by older adults of at least 70 years of age.
Methods
A cross-sectional questionnaire study was conducted among persons of ≥70 years from metropolitan Berlin and rural parts of Brandenburg, Germany. Recorded were: demographics, current use of CAM, medical diagnoses, users’ opinions and preferences.
Results
A total of 400 older adults, living as ‘self-reliant’ (n = 154), ‘home care service user’ (n = 97), or ‘in nursing home’ (n = 149), and with the legal status ‘without guardian’ (n = 355) or ‘with guardian’ (n = 45) were included (mean age 81.8 ± 7.4 years, 78.5% female). Any type of CAM used 61.3% of respondents (dietary supplements 35.5%, herbal medicines 33.3%, and external preparations 26.8%); 3.0% used drug-interaction causing preparations. Usage was based on recommendations (total 30.3%; in 20.0% by friends or family and 10.4% by pharmacists), own initiative (27.3%), and doctors’ prescription (25.8%). Participants with legal guardian took almost solely prescribed dietary supplements. Of the others, only half (58.7%) informed their general practitioner (GP) of their CAM use. Participants expected significant (44.9%) or moderate (37.1%) improvement; half of them perceived a good effect (58.7%) and two-thirds (64.9%) generally preferred a combination of CAM and conventional medicine. More than half (57.9%) stated that they could neither assess whether their CAM preparations have side effects, nor assess what the side effects might be. Strongest predictors for CAM use were two treatment preferences (vs. ‘conventional only’: ‘CAM only’, OR = 3.98, p = 0.0042 and ‘CAM + conventional’, 3.02, 0.0028) and the type of health insurance (‘statutory’ vs. ‘private’, 3.57, 0.0356); against CAM use two subjective assessments predicted (vs. ‘CAM causes no harm’: ‘CAM causes harmful drug interactions’, 0.25, 0.0536 and ‘I cannot assess side effects’, 0.28, 0.0010).
Conclusion
Older German adults frequently use CAM. They perceived it as an effective complement to conventional medicine, but are not sufficiently informed about risks and benefits.

23.  Clinical trial participants’ experiences of completing questionnaires: a qualitative study 
BMJ Open  2014;4(3):e004363.
Objectives
To improve clinical study developments for elderly populations, we aim to understand how they transfer their experiences into validated, standardised self-completed study measurement instruments. We analysed how women (mean 78±8 years of age) participating in a randomised controlled trial (RCT) cognised study instruments used to evaluate outcomes of the intervention.
Setting
The interview study was nested in an RCT on chronic neck pain using common measurement instruments situated in an elderly community in Berlin, Germany, which comprised of units for independent and assisted-living options.
Participants
The sample (n=20 women) was selected from the RCT sample (n=117, 95% women, mean age 76 (SD±8) years). Interview participants were selected using a purposive sampling list based on the RCT outcomes.
Outcomes
We asked participants about their experiences completing the RCT questionnaires. Interviews were analysed thematically, then compared with the questionnaires.
Results
Interviewees had difficulties in translating complex experiences into a single value on a scale and understanding the relationship of the questionnaires to study aims. Interviewees considered important for the trial that their actual experiences were understood by trial organisers. This information was not transferrable by means of the questionnaires. To rectify these difficulties, interviewees used strategies such as adding notes, adding response categories or skipping an item.
Conclusions
Elderly interview participants understood the importance of completing questionnaires for trial success. This led to strategies of completing the questionnaires that resulted in ‘missing’ or ambiguous data. To improve data collection in elderly populations, educational materials addressing the differential logics should be developed and tested. Pilot testing validated instruments using cognitive interviews may be particularly important in such populations. Finally, when the target of an intervention is a subjective experience, it seems important to create a method by which participants can convey their personal experiences. These could be nested qualitative studies.

24.  The perspectives of older women with chronic neck pain on perceived effects of qigong and exercise therapy on aging: a qualitative interview study 
Chronic pain is prevalent in elderly populations. The goals of this study were 1) to understand the results of a randomized clinical trial – Qigong and Exercise Therapy for Elderly Patients with Chronic Neck Pain (QIBANE) – that showed no difference between qigong, exercise therapy, and no-treatment on quality of life, and 2) to understand how elderly individuals with chronic pain experience interventions of qigong and exercise therapy. A qualitative interview study was conducted with 20 QIBANE participants. Interviews asked about motivation for and expectations of trial participation, experiences with the exercise classes (qigong or exercise therapy), and changes in pain experience. Interviews were transcribed, entered into the software program ATLAS.ti, and coded thematically by two coders. Content analysis was performed. All interviewees reflected positively on their QIBANE experience and described their participation in QIBANE as helpful. However, what was discussed in both groups when they talked about “positive experiences” in the study differed between the two groups. For example, themes that emerged in the exercise-therapy group related to difficulties associated with aging and staying physically active. In the interviews with qigong group members, emergent themes related to qigong as a method that improved bodily experiences and influenced daily activities. The effects that exercise therapy and qigong have on an elderly population cannot be captured by health-related quality-of-life measurements, such as the Short Form (36) Health Survey. Broader concepts of quality of life that include the concepts of self-efficacy and positive affect may be more appropriate. The results presented in this study suggest that for this population group, the approach of patient-centered outcomes is especially pertinent in order to design meaningful intervention studies in the elderly. This means that research questions, interventions, and outcome measurements need to take into account the special situation of elderly people.

25.  Responses to the Acupuncture Trialists' Collaboration individual patient data meta-analysis 
In September 2012, the Acupuncture Trialists' Collaboration published the results of an individual patient data meta-analysis of close to 18,000 patients in high quality-randomized trials. The results favored acupuncture. Although there was little argument about the findings in the scientific press, a controversy played out in blog posts and the lay press. This controversy was characterized by ad hominem remarks, anonymous criticism, phony expertise, and the use of opinion to contradict data, predominately by self-proclaimed skeptics. There was a near complete absence of substantive scientific critque. The lack of any reasoned debate about the main findings of the Acupuncture Trialists' Collaboration paper underlines that mainstream science has moved on from the intellectual sterility and ad hominem attacks that characterize the skeptics’ movement.
