Widespread use of pure and impure placebo interventions by GPs in Germany

Aim. To collect data on the use of placebo interventions by GPs in Germany. Methods. A questionnaire was mailed to 400 randomly selected GPs in Bavaria. Non-responders were reminded by telephone after 4 weeks and were given a second copy of the questionnaire after a further 3 weeks. Results. In all, 208 completed questionnaires were returned. The majority of GPs (88%) have used a placebo at least once in their practice; 45% have used pure placebos, such as saline injections and sugar pills, at least once last year; the median frequency of use was 5 [interquartile range (IQR), 2-10]. The use of impure placebos during the past year was more common: 76% of GPs have used impure placebos, i.e. medical interventions that have pharmacological or physical activity but have no intrinsic effect (e.g. pharmacological or physical action) on the patient's disease or its symptoms, with a median frequency of 20 times per year (IQR, 10-50). The main reason for the use of placebo was a possible psychological effect, followed by the expectation of patients to receive a treatment. For the majority of GPs placebo interventions were ethically justified if they were used for a possible psychological effect. Conclusions. Placebo interventions are a widely accepted part of medical treatment in German general practices and are used primarily for their psychological effects. Impure placebos are used much more frequently than pure placebo

Impact of the DRG-based reimbursement system on patient care and professional practise: perspectives of Swiss hospital physicians

QUESTIONS UNDER STUDY: The reimbursement system SwissDRG sets incentives for hospitals and providers to treat patients in a cost-efficient way. Arising conflicts between the commitment to the patient’s well-being and the economic interests of the hospital can lead to an impairment of quality and equity of health care. We developed and used a monitoring tool to evaluate ethically relevant aspects related to DRGs by surveying physicians. METHODS: We surveyed a random sample of physicians working in Swiss hospitals, exploring potentially positive and negative effects of DRGs on patient care. RESULTS: A total of 382 physicians completed the questionnaire (response rate 47%). More than 90% judged quality of health care “very good” or “rather good”, and 83% were satisfied with their job. The majority of physicians gave more consideration to economic issues in their clinical practise than they would have liked and had experienced various forms of over- and under-provision over the past six months. Overall, physicians considered patient-orientation deteriorating since the introduction of DRGs with no gains in efficiency. Professional principles could not be applied in all instances. CONCLUSIONS: Two years after the introduction of SwissDRG the quality of patient care and the job satisfaction is rated as good by most physicians. However, quality of care could be seriously compromised if more economic pressure is put on physicians in the future. Careful monitoring is needed to ensure that the needed focus on cost-containment and sustainability does not come at the expense of the high performance of the Swiss health care system

The use of pure and impure placebo interventions in primary care - a qualitative approach

Background: Placebos play an important role in clinical trials and several surveys have shown that they are also common in daily practice. Previous research focused primarily on the frequency of placebo use in outpatient care. Our aim was to explore physicians' views on the use of placebos in daily practice, whereby distinction was made between pure placebos (substances with no pharmacological effect, e.g. sugar pills) and impure placebos (substances with pharmacological effect but not on the condition being treated, e.g. antibiotics in viral infections or vitamins). Methods: We performed semi-structured interviews with a sample of twelve primary care physicians (PCPs). The interview addressed individual definitions of a placebo, attitudes towards placebos and the participants' reasons for prescribing them. The interviews were transcribed and analysed using qualitative content analysis. Results: The definition of a placebo given by the majority of the PCPs in our study was one which actually only describes pure placebos. This definition, combined with the fact that most impure placebos were not regarded as placebos at all, means that most of the participating PCPs were not aware of the extent to which placebos are used in daily practice. The PCPs stated that they use placebos (both pure and impure) mainly in the case of non-severe diseases for which there was often no satisfactory somatic explanation. According to the PCPs, cases like this are often treated by complementary and alternative therapies and these, too, are associated with placebo effects. However, all PCPs felt that the ethical aspects of such treatment were unclear and they were unsure as to how to communicate the use of placebos to their patients. Most of them would appreciate ethical guidelines on how to deal with this issue. Conclusions: Many PCPs seem to be unaware that some of the drugs they prescribe are classified as impure placebos. Perceptions of effectiveness and doubts about the legal and ethical aspects of the use of placebos by PCPs may discourage their application. Dissemination of guidelines and consensus papers may be one approach, but it has to be acknowledged that the topic itself is in conflict with the PCPs' perception of themselves as professional and reliable physicians

Assessing the impact of DRGs on patient care and professional practice in Switzerland (IDoC) : a potential model for monitoring and evaluating healthcare reform.

QUESTIONS UNDER STUDY: The starting point of the interdisciplinary project "Assessing the impact of diagnosis related groups (DRGs) on patient care and professional practice" (IDoC) was the lack of a systematic ethical assessment for the introduction of cost containment measures in healthcare. Our aim was to contribute to the methodological and empirical basis of such an assessment. METHODS: Five sub-groups conducted separate but related research within the fields of biomedical ethics, law, nursing sciences and health services, applying a number of complementary methodological approaches. The individual research projects were framed within an overall ethical matrix. Workshops and bilateral meetings were held to identify and elaborate joint research themes. RESULTS: Four common, ethically relevant themes emerged in the results of the studies across sub-groups: (1.) the quality and safety of patient care, (2.) the state of professional practice of physicians and nurses, (3.) changes in incentives structure, (4.) vulnerable groups and access to healthcare services. Furthermore, much-needed data for future comparative research has been collected and some early insights into the potential impact of DRGs are outlined. CONCLUSIONS: Based on the joint results we developed preliminary recommendations related to conceptual analysis, methodological refinement, monitoring and implementation

Use of placebo interventions among Swiss primary care providers

Background: Placebo interventions can have meaningful effects for patients. However, little is known about the circumstances of their use in clinical practice. We aimed to investigate to what extent and in which way Swiss primary care providers use placebo interventions. Furthermore we explored their ideas about the ethical and legal issues involved. Methods: 599 questionnaires were sent to general practitioners (GPs) and paediatricians in private practice in the Canton of Zurich in Switzerland. To allow for subgroup analysis GPs in urban, suburban, and rural areas as well as paediatricians were selected in an even ratio. Results: 233 questionnaires were completed (response rate 47%). 28% of participants reported that they never used placebo interventions. More participants used impure placebos therapeutically than pure placebos (57% versus 17%, McNemar's chi2 = 78, p<0.001). There is not one clear main reason for placebo prescription. Placebo use was communicated to patients mostly as being "a drug or a therapy" (64%). The most frequently chosen ethical premise was that they "can be used as long as the physician and the patient work together in partnership" (60% for pure and 75% for impure placebos, McNemar's chi2 = 12, p<0.001). A considerable number of participants (11-38%) were indecisive about statements regarding the ethical and legal legitimacy of using placebos. Conclusions: The data obtained from Swiss primary care providers reflect a broad variety of views about placebo interventions as well as a widespread uncertainty regarding their legitimacy. Primary care providers seem to preferentially use impure as compared to pure placebos in their daily practice. An intense debate is required on appropriate standards regarding the clinical use of placebo interventions among medical professionals

Development and validation of a tool to assess researchers’ knowledge of human subjects’ rights and their attitudes toward research ethics education in Saudi Arabia

Abstract Background Researchers must adhere to ethical and scientific standards in their research involving human subjects; therefore, their knowledge of human subjects’ rights is essential. A tool to measure the extent of this knowledge is necessary to ensure that studies with participants are conducted ethically and to enhance research integrity. Currently, no validated instrument is available for such an assessment. Therefore, the primary purpose of this study is to develop a reliable and valid instrument to assess researchers’ knowledge of human subjects’ rights in clinical settings, as well as a reliable and valid measure of their attitudes toward clinical research ethics education in Saudi Arabia. Methods The current study involves the development of a questionnaire about the rights of human subjects in research and the researchers’ attitudes toward research ethics education. The content was developed based on an extensive review of research ethics guidelines. A panel of experts tested the questionnaire for face validity (n = 5) and content validity (n = 8). The reliability of the questionnaire was established by a split-half reliability coefficient and item analysis among a sample (n = 301) of clinical researchers. Results Face validity demonstrated that the questionnaire was quick to complete and easy to answer. The global content validity indices (S-CVIs) were greater than 0.78 for all questionnaire sections; the split-half reliability coefficient was 0.755 for knowledge items; Cronbach’s alpha was 0.77 for researchers’ attitudes, showing good internal consistency. The difficulty index ranged from 12.0% to 98.7% for all knowledge items. Most questions were at an acceptable level of reliability and discrimination criteria. The final version of the questionnaire contained 89 items, distributed as 15 questions on demographic and professional characteristics, 64 questions items on knowledge, and 10 items on attitudes. Conclusions The questionnaire is a valid and reliable tool to assess biomedical researchers’ knowledge of human subjects’ rights and their attitudes toward research ethics education. This instrument could help address the gap in researchers’ knowledge of the rights and facilitate the development of educational intervention programs to set appropriate learning objectives

Bonus agreements of senior physicians in Switzerland - a qualitative interview study

In Switzerland a legal prohibition of volume-based bonus agreements has been initiated which is expected to take force at the beginning of 2021. Bonus agreements for physicians pose a risk to unbiased indication, possibly leading to over-, under- and misuse of medical care. In order to investigate physicians' perceptions of bonus agreements and reflect on them from an ethical point of view, we conducted a qualitative interview study with Swiss senior physicians. The remuneration system is complex and diverse so that the interviewed physicians were not always able to explain in detail to which targets the variable components of their salary were linked. Study participants were aware of their ethical responsibility regarding non-biased indication and cost-effective medicine. All rejected volume-based bonus agreements. Target agreements should generally have a clear, comprehensible function and always contain a component related to the quality of care delivered. Critical attention should go beyond a narrow focus on volume-based bonus agreements to include other volume-oriented target agreements and reimbursement systems that have the potential to negatively affect patient care

Placebo interventions in practice: a questionnaire survey on the attitudes of patients and physicians

GPs rather underestimate the openness of their patients to non-specific therapies. However, patients want to be appropriately informed. Developing specific professional standards could help physicians to harness the 'power of the placebo', while remaining authentic and credibl
