Two New Papers

Shin Y, Shin JS, Lee J, Lee YJ, Kim M, Ahn YA, Park KB, Shin BC, Lee MS, Kim JH, Cho JH, He IH.  survey among Korea Medicine doctors (KMDs) in Korea on patterns of integrative Korean Medicine practice for lumbar intervertebral disc displacement: Preliminary research for clinical practice guidelines. BMC Comple Alternative Med 201515:432, DOI: 10.1186/s12906-015-0956-1

ABSTRACT
Background: Patients seek Korean Medicine (KM) treatment for a broad range of complaints in Korea, but predominantly for musculoskeletal disorders. We investigated lumbar Intervertebral Disc Displacement (IDD) practice patterns of Korean Medicine doctors (KMDs) within a hospital/clinic network specializing in KM treatment of spinal disorders through survey of diagnosis and treatment methods.

Methods: Questionnaires on clinical practice patterns of KM treatment for lumbar IDD were distributed to 149 KMDs on January 25th, 2015. The questionnaire included items on sociodemographic characteristics, clinical practice patterns, and preferred method of lumbar IDD diagnosis and treatment. KMDs were asked to grade each treatment method for absolute and relative importance in treatment and prognosis, and safety.
Results: A total 79.19 % KMDs (n = 118/149) completed the survey, and results showed that integrative care mainly consisting of acupuncture, herbal medicine, Chuna manipulation, and pharmacopuncture was administered to IDD patients. The participant KMDs largely relied on radiological findings (MRI and X-ray) for diagnosis. ‘Eight principle pattern identification’, ‘Qi and Blood syndrome differentiation’ and ‘Meridian system syndrome differentiation’ theories were generally used for KM syndrome differentiation. The most frequently prescribed herbal medication was Chungpa-jun, and most commonly used Chuna technique was ‘sidelying lumbar extension displacement treatment’. IDD patients received 1.9 ± 0.3 treatment sessions/week, and KMDs estimated that an average 9.6 ± 3.5 weeks were needed for 80 % pain relief.

Conclusions: This is the first study to investigate expert opinion on KM treatment of IDD. Further randomized controlled trials and clinical guidelines based on clinical practice patterns of KM are called for

Hung CH, Lin CY. Using concept mapping to evaluate knowledge structure in problem-based learning. BMC Med Educ201515:212, DOI: 10.1186/s12909-015-0496-x
ABSTRACT

Background: Many educational programs incorporate problem-based learning (PBL) to promote students’ learning; however, the knowledge structure developed in PBL remains unclear. The aim of this study was to use concept mapping to generate an understanding of the use of PBL in the development of knowledge structures.
Methods: Using a quasi-experimental study design, we employed concept mapping to illustrate the effects of PBL by examining the patterns of concepts and differences in the knowledge structures of students taught with and without a PBL approach. Fifty-two occupational therapy undergraduates were involved in the study and were randomly divided into PBL and control groups. The PBL group was given two case scenarios for small group discussion, while the control group continued with ordinary teaching and learning. Students were asked to make concept maps after being taught about knowledge structure. A descriptive analysis of the morphology of concept maps was conducted in order to compare the integration of the students’ knowledge structures, and statistical analyses were done to understand the differences between groups.

Results: Three categories of concept maps were identified as follows: isolated, departmental, and integrated. The students in the control group constructed more isolated maps, while the students in the PBL group tended toward integrated mapping. Concept Relationships, Hierarchy Levels, and Cross Linkages in the concept maps were significantly greater in the PBL group; however, examples of concept maps did not differ significantly between the two groups.
Conclusions: The data indicated that PBL had a strong effect on the acquisition and integration of knowledge. The important properties of PBL, including situational learning, problem spaces, and small group interactions, can help students to acquire more concepts, achieve an integrated knowledge structure, and enhance clinical reasoning.

Remembering the Framework of a Scientific Paper


The general organization of a scientific paper is as follows: abstract; introduction; methods; results, discussion; conclusion; references.

The Abstract should be structured, unless journal protocol says to use a narrative form. The abstract should tell the reader what question you asked, explain what methods were used to answer the question, what was found and what was concluded. All in 250 words or less.
The Introduction should, well, introduce the topic of the paper, describe briefly some background information the gap in the literature your paper will address, and close by providing the reader with the actual research question.
The Methods section should describe how the research was done. It should provide enough detail that an interested reader could replicate what you did. It is, for example, not enough to simply say that some was adjusted using side-posture positioning; your paper should fully describe how the adjustment was rendered.
The Results should provide the answer to the question you asked, along with supplementary information that has helped address the question. Generally, this is provided as group mean values, depending on the kind of paper and the statistics used.
The Discussion provides context and discusses the findings of your paper in light of what is already known. It helps to put your work into that larger context and also again addresses what is new and novel about your work. It usually concludes by providing additional research direction.
The Conclusion really just summarizes what you have already reported in your paper. It, too, can offer future direction.
References are done to journal style. In most biomedical journals, this is using Vancouver formatting. This is a numerical system. Note that variants of this system exist, so note the journal style requirements.
This is the briefest of overviews of a scientific paper, but it helps to keep this all in mind when you sit down to write.

Notice of Proposed Rulemaking 2015- Summary


(Dear Colleagues- this is the specific language offered by the US Department of Helath and Human Services, related to changes in the Common Rule, 45CFR46, which governs our use of human subjects in research. In future articles I will discuss the implications of this proposed rule change).

The U.S. Department of Health and Human Services and fifteen other Federal Departments and Agencies have announced proposed revisions to modernize, strengthen, and make more effective the Federal Policy for the Protection of Human Subjects that was promulgated as a Common Rule in 1991.  A Notice of Proposed Rulemaking (NPRM) was published in the Federal Register on September 8, 2015 (PDF 1063 KB). The NPRM seeks comment on proposals to better protect human subjects involved in research, while facilitating valuable research and reducing burden, delay, and ambiguity for investigators.

Some of the major changes being proposed that will better protect research subjects and help build public trust are the rules relating to informed consent. With regard to informed consent in general (such as consent to participating in clinical trials), the rules would be significantly tightened to make sure that the process becomes more meaningful. Consent forms would no longer be able to be unduly long documents, with the most important information often buried and hard to find. They would need to give appropriate details about the research that is most relevant to a person’s decision to participate in the study, such as information a reasonable person would want to know, and present that information in a way that highlights the key information. In addition, to assure that these rules do indeed change current practices, there will be a one-time posting requirement for the consent forms for clinical trials, so that anyone drafting a consent form will do so knowing that it will eventually be subject to public scrutiny.

In addition, informed consent would generally be required for secondary research with a biospecimen (for example, part of a blood sample that is left over after being drawn for clinical purposes), even if the investigator is not being given information that would enable him or her to identify whose biospecimen it is. Such consent would not need to be obtained for each specific research use of the biospecimen, but rather could be obtained using a “broad” consent form in which a person would give consent to future unspecified research uses.

The NPRM also attempts to strengthen the effectiveness and efficiency of the oversight system by making the level of review more proportional to the seriousness of the harm or danger to be avoided. Research that poses greater risk to subjects should receive more oversight and deliberation than less risky research. The NPRM seeks to avoid requirements that do not enhance protection and impose burden, which can decrease efficiency, waste resources, erode trust, and obscure the true ethical challenges that require careful deliberation and stakeholder input. Cumbersome and outdated regulatory standards overwhelm and distract institutions, IRBs, and investigators in ways that stymie efforts to appropriately address the real risks and benefits of research. 

The result of these types of changes, as the NPRM proposes to implement them, is that some studies that currently require IRB review would now become exempt. Some that are currently exempt would specifically be declared as outside the scope of the regulations (“excluded”), and thus would not require any administrative or IRB review. Further, in terms of determining when a study is exempt, a web-based “decision tool” will be created. That decision tool will provide a determination of whether or not a study is exempt. That result, so long as the tool was provided with accurate information, will be presumed by the Common Rule agencies to be an appropriate determination of exempt status. It is expected that in many instances the tool would be used by the investigators themselves, thus obviating both the need for further review and the concern that the institution might be subjecting itself to future liability by allowing investigators to use the tool.  For all of the excluded and exempt research activities, this NPRM also affirms the importance of applying the ethical principle of respect for persons, in addition to the importance of abiding by this principle in fully regulated non-exempt research involving human subjects. 

The following list encompasses the most significant changes to the Common Rule proposed in the NPRM:
1.    Improve informed consent by increasing transparency and by imposing stricter new requirements regarding the information that must be given to prospective subjects, and the manner in which it is given to them, to better assure that subjects are appropriately informed before they decide to enroll in a research study.

2.    Generally require informed consent for the use of stored biospecimens in secondary research (for example, part of a blood sample that is left over after being drawn for clinical purposes), even if the investigator is not being given information that would enable him or her to identify whose biospecimen it is. That consent would generally be obtained by means of broad consent (i.e., consent for future, unspecified research studies) to the storage and eventual research use of biospecimens.

3.    Exclude from coverage under the Common Rule certain categories of activities that should be deemed not to be research, are inherently low risk, or where protections similar to those usually provided by IRB review are separately mandated.

4.    Add additional categories of exempt research to accommodate changes in the scientific landscape and to better calibrate the level of review to the level of risk involved in the research. A new process would allow studies to be determined to be exempt without requiring any administrative or IRB review. Certain exempt and all non-exempt research would be required to provide privacy safeguards for biospecimens and identifiable private information. New categories include:
  • a.    certain research involving benign interventions with adult subjects;
  • b.    research involving educational tests, surveys, interviews or observations of public behavior when sensitive information may be collected, provided that data security and information privacy protections policies are followed;
  • c.    secondary research use of identifiable private information originally collected as part of a non-research activity, where notice of such possible use was given;
  • d.    storing or maintaining biospecimens and identifiable private information for future, unspecified secondary research studies, or conducting such studies, when a broad consent template to be promulgated by the Secretary of HHS is used, information and biospecimen privacy safeguards are followed, and limited IRB approval of the consent process used is obtained.
5.    Change the conditions and requirements for waiver or alteration of consent such that waiver of consent for research involving biospecimens (regardless of identifiability) will occur only in very rare circumstances.

6.    Mandate that U.S. institutions engaged in cooperative research rely on a single IRB for that portion of the research that takes place within the United States, with certain exceptions.  To encourage the use of IRBs that are otherwise not affiliated with or operated by an assurance-holding institution (“unaffiliated IRBs”), this NPRM also includes a proposal that would hold such IRBs directly responsible for compliance with the Common Rule.

7.    Eliminate the continuing review requirement for studies that undergo expedited review and for studies that have completed study interventions and are merely analyzing data or involve only observational follow-up in conjunction with standard clinical care.

8.    Extend the scope of the policy to cover all clinical trials, regardless of funding source, conducted at a U.S. institution that receives federal funding for non-exempt human subjects research.

In sum, the proposed modifications described above are designed to continue to uphold the ethical principles upon which the Common Rule is based, as applied to the current social, cultural, and technological environment.

New Papers

Kelly MP, Heath I, Howick J, Greenhalgh T. The importance of values in evidence-based medicine. BMC Medical Ethics 2015, 16:69  doi:10.1186/s12910-015-0063-3

ABSTRACT
Background: Evidence-based medicine (EBM) has always required integration of patient values with ‘best’ clinical evidence. It is widely recognized that scientific practices and discoveries, including those of EBM, are value-laden. But to date, the science of EBM has focused primarily on methods for reducing bias in the evidence, while the role of values in the different aspects of the EBM process has been almost completely ignored.
Discussion: In this paper, we address this gap by demonstrating how a consideration of values can enhance every aspect of EBM, including: prioritizing which tests and treatments to investigate, selecting research designs and methods, assessing effectiveness and efficiency, supporting patient choice and taking account of the limited time and resources available to busy clinicians. Since values are integral to the practice of EBM, it follows that the highest standards of EBM require values to be made explicit, systematically explored, and integrated into decision making.

Summary: Through ‘values based’ approaches, EBM’s connection to the humanitarian principles upon which it was founded will be strengthened.

ABSTRACT
Randomised trials can provide excellent evidence of treatment benefit in medicine. Over the last 50 years, they have been cemented in the regulatory requirements for the approval of new treatments. Randomised trials make up a large and seemingly high-quality proportion of the medical evidence-base. However, it has also been acknowledged that a distorted evidence-base places a severe limitation on the practice of evidence-based medicine (EBM). We describe four important ways in which the evidence from randomised trials is limited or partial: the problem of applying results, the problem of bias in the conduct of randomised trials, the problem of conducting the wrong trials and the problem of conducting the right trials the wrong way. These problems are not intrinsic to the method of randomised trials or the EBM philosophy of evidence; nevertheless, they are genuine problems that undermine the evidence that randomised trials provide for decision-making and therefore undermine EBM in practice. Finally, we discuss the social dimensions of these problems and how they highlight the indispensable role of judgement when generating and using evidence for medicine. This is the paradox of randomised trial evidence: the trials open up expert judgment to scrutiny, but this scrutiny in turn requires further expertise.

ABSTRACT
Background: Interprofessional collaboration is considered a key-factor to deliver the highest quality of care. Interprofessional collaboration (IPC) assumes a model of working together, in particular with awareness of the process of interprofessional collaboration, to develop an integrated and cohesive answer to the needs of the client/family/population. Educational modules are developed in response to a perceived need to improve interprofessional collaboration for the benefit of patientcare. Up until 2005 no explicit module on interprofessional collaboration existed in the education programs of the Antwerp University Association (AUHA). During a decade the ‘Interprofessional Collaboration In Healthcare (IPCIHC) – module’ is organised and evaluated by its participants.

Methods: One group, post-test design was used to gather data from the participating students using a structured questionnaire. Data was collected between March 2005 and March 2014 from participating final year students in healthcare educational programs.
Results: 3568 (84 % overall response) students evaluated the IPCIHC module from 2005 up to 2014. Over 80 % of the participants were convinced the IPCIHC increased their knowledge and changed their understanding that it will impact their future professional relationships, and felt a greater understanding about problem-solving in healthcare teams. Even though the results indicate that the goals of the IPCIHC module were achieved, less than 60 % of the participants experienced a change in attitude towards other professional groups.

Conclusions: Despite the positive outcomes from the participants, the challenge still remains to keep on educating future healthcare providers in interprofessional collaboration in order to achieve an increase in interprofessional behaviour towards other professional groups. Research is needed to investigate the effectiveness of undergraduate programs on the quality and safety of patientcare in practice.
