In speaking of multidisciplinary care, we can forget that such care involves more than a multidisciplinary group comprised Introduction of physicians. True collegiality involves collaboration with Like college and colleagues, the word collegiality derives from other health care disciplines, and there is much that each can the Latin collegere: to read together. Having said that, collegiality between collaborators in common pursuits, or having common duties and interests, is not automatic. It needs to be fostered and nurtured with re- and sometimes, by charter, peculiar rights and privileges.

In such a setting, Society does not appreciate a self-protective collegiality that a collegial faculty would be one that values a commitment to circles the wagons around questionable professional behav- the sharing of knowledge. And so it is important to remember that, like everyone else, physicians get sick and grow old, and that in the process their competence can be compromised. As is discussed elsewhere in this handbook, certain aspects of the culture of medicine, together with typi- cal attributes that otherwise hold physicians in good stead, can make physicians reluctant to admit when they fnd themselves in diffculty. However, the physician s responsibility to maintain his or her own health in order to practise safely also extends to a collegial duty to be aware of the health and ftness of others. Case resolution In the past, ill physicians, worried that their medical licence It is important for any organization or group to cultivate might be put in jeopardy, remained silent until a complaint was collegiality and mentorship. In this case, rumours are reported to a regulatory body or an adverse event occurred.

Workplaces should have mechanisms in however, for a trusted colleague or colleagues to respect- place to ensure that potentially impaired practitioners promptly fully ask to meet with the resident privately and to present cease practice until their ftness to practise can be assessed. It would be appropriate to offer assistance Too often, however, a misguided sense of collegiality makes in connecting the resident with a personal physician if the physicians hesitate to respond to a colleague in diffculty or resident doesn t have one.

Toward Precision Medicine: Building a Knowledge Network for Biomedical Research and a New Taxonomy of Disease 54 was simply to ask the question Are there gene variants in the general population that are associated with who ends up with a particular diagnosis or experiences a particular treatment response? For example phenazopyridine 200 mg with amex, there are likely to be a great many ways to classify patients based on molecular data, and only some will have clinical utility. In general, clinical utility will need to be evaluated using randomized clinical trials. Observational studies will also need to be followed by functional studies that seek to determine the mechanistic basis of observed molecular associations with clinical outcomes. We anticipate that laboratory based research of this sort will be essential to elucidate the underlying reasons for observed associations between molecular data and clinical outcomes and that these mechanistic insights will play an essential part in establishing the Knowledge Network and guiding its use. Be of a sufficient size, as well as scientific and organizational complexity, to reveal on the basis of actual experience the most significant barriers to the development of point- of-care discovery efforts. Address one or more unmet medical needs for which deeper biological understanding of a disorder would likely lead to near-term changes in treatment paradigms and health outcomes. Be led by an organization charged with delivering healthcare with strong partnerships with researchers. Seek to remove barriers to data sharing and provide an ethical and legal framework for protecting and respecting individual rights. Draw on laboratory research to assess the biological underpinnings of associations between molecular data and clinical outcomes. Toward Precision Medicine: Building a Knowledge Network for Biomedical Research and a New Taxonomy of Disease 55 Below, we outline two example pilot studies; the first, The Million American Genomes Initiative, is selected to pilot the use of one of the key layers of omic information that is "ready to go". This pilot project would help to populate the Information Commons with relevant data and facilitate learning how to establish connections with other layers. By focusing on healthcare recipients in diverse states of health and disease, this project would also help evaluate the new discovery paradigm by allowing correlations to be made between germline sequences and a vast range of phenotypes. The second Metabolomic profiles in Type 2 Diabetes is disease specific and is designed to ensure the early introduction of a different omic layer (metabolomics) into the Information Commons and to pilot evaluation of more targeted questions in the new discovery paradigm. In focusing on a pilot study involving complete sequence data, we do not intend to elevate sequence data above other data in their importance to the Knowledge Network. This proposal also recognizes that sequencing on this scale will inevitably be undertaken in the near future in an effort to make connections between human-genome-sequence data and common diseases. We view it as important to the development of the Knowledge Network that this effort be grounded in the new discovery model, which would make possible systematic comparisons of the molecular data with electronic medical records, now and into the future: that is, the study design should allow correlations between genotypes determined now and health outcomes that occur years or decades later. The sequencing of one million genomes would include a sufficient range of individuals with different health outcomes and sufficient statistical power to detect associations. For example, amoxicillin-clavulanic acid is a widely used antibiotic that causes severe liver injury in one out of approximately 15,000 exposures. In a one-million-patient sample we would expect to include many individuals with this and other similarly rare adverse drug reactions and other medical conditions. It is also essential that the sample size be large enough to build a concrete picture of the distribution of gene variants in individuals free of specific diagnoses. Example Pilot Study 2: Metabolomic profiles in Type 2 Diabetes Recent metabolomic profiling of blood samples from individuals who subsequently developed type 2 diabetes showed marked differences in the characteristics of branched-chain amino acids sampled from blood draws (Wang et al. These early analyses suggest the potential of metabolomic analyses to help identify those individuals at most risk of developing diabetes, and in particular, may help to elucidate the physiological steps involved in the transition between insulin resistant pre-diabetes and full-blown diabetes. We therefore envision a pilot project focused on understanding this transition using metabolomic profiles in blood. This work would begin with targeted quantitative metabolomic studies transitioning towards more comprehensive metabolomic profiles over time. Toward Precision Medicine: Building a Knowledge Network for Biomedical Research and a New Taxonomy of Disease 56 gained from Pilot 1 and research from other layers of the Information Commons (such as the microbiome and exposome) could contribute substantially to strategies to delay or prevent the development of type 2 diabetes. Anticipated outcomes of the pilot studies The pilot studies are intended to lead to new connections between genetic or metabolomic variation and disease sub-classifications, often with implications for disease management and prevention. More importantly, they will provide the lessons necessary to facilitate a more rapid transition in the way molecular data are used. For example, pilot projects of sufficient scope and scale could lead to the development of new discovery models, including those in which patient groups self-organize in recognition of shared clinical features and then pursue efforts to generate relevant molecular data. Such an initiative also would permit many logistical, ethical, and bioinformatic challenges to be addressed in ways that would benefit future efforts and lead toward the sustainable implementation of point-of-care discovery efforts. The Committee s vision of a Knowledge Network of Disease and its associated benefits for future patients will become a reality only if the public supports a new balance between research access to materials and clinical data and respect for the values and preferences of donors. Ultimately, there should be no dichotomy between patient data or materials and those who benefit from this research. How might these ethical and policy challenges be resolved so that the pilot studies described previously might be carried out?
