    With the proliferation of rare disease registries, there is a need for registries to undergo an assessment of their quality against agreed standards to ensure their long-term sustainability and acceptability.This study was performed to evaluate the I-DSD and I-CAH Registries and identify their strengths and weaknesses. The design and operational aspects of the registries were evaluated against published quality indicators. Additional criteria included the level of activity, international acceptability of the registries and their use for research. The design of the I-DSD and I-CAH Registries provides them with the ability to perform multiple studies and meet the standards for data elements, data sources and eligibility criteria. The registries follow the standards for data security, governance, ethical and legal issues, sustainability and communication of activities. The data have a high degree of validity, consistency and accuracy and the completeness is maximal for specific conditions such as androgen insensitivity syndrome and congenital adrenal hyperplasia. In terms of research output, the external validity is strong but the wide variety of cases needs further review. The internal validity of data was condition specific and highest for conditions such as congenital adrenal hyperplasia. The shift of the registry from a European registry to an international registry and the creation of a discrete but linked CAH registry increased the number of users and stakeholders as well as the international acceptability of both registries. The I-DSD and I-CAH registries comply with the standards set by expert organisations. Recent modifications in their operation have allowed the registries to increase their user acceptability

    Contextualized B2B Registries

    Abstract. Service discovery is a fundamental concept underpinning the move towards dynamic service-oriented business partnerships. The business process for integrating service discovery and underlying registry technologies into business relationships, procurement and project management functions has not been examined and hence existing Web Service registries lack capabilities required by business today. In this paper we present a novel contextualized B2B registry that supports dynamic registration and discovery of resources within management contexts to ensure that the search space is constrained to the scope of authorized and legitimate resources only. We describe how the registry has been deployed in three case studies from important economic sectors (aerospace, automotive, pharmaceutical) showing how contextualized discovery can support distributed product development processes

    UK donor registries

    Fertility services have been formally regulated in the UK since 1991, following implementation of the Human Fertilisation and Embryology Act 1990 (“The Act”). The Act established a statutory regulatory agency, the Human Fertilisation and Embryology Authority (HFEA), whose responsibilities include licensing certain forms of fertility treatment and to maintain a register of information (s31). The register includes details relating to donors, recipients of donated gametes and embryos, and children born as a result of all donor procedures provided by a licensed treatment centr

    Credit reporting and financing constraints

    The authors combine firm-level data from the World Bank Business Environment Survey (WBES) with data on private and public credit registries to investigate whether the presence of a credit registry in a country is associated with lower financing constraints, as perceived by managers, and with higher share of bank financing. They find that the existence of private credit registries is associated with lower financing constraints and higher share of bank financing, while the existence of public credit registries does not seem to have a significant effect on these perceived financing constraints. The authors also find that small- and medium-sized firms tend to have a higher share of bank financing in countries where private registries exist and stronger rule of law is associated with more effective private credit registries. Finally, the authors find some evidence that the presence of a public credit registry benefits younger firms relatively more than older firms.Financial Intermediation,Payment Systems&Infrastructure,Environmental Economics&Policies,Banks&Banking Reform,International Terrorism&Counterterrorism,Financial Intermediation,Housing Finance,Environmental Economics&Policies,National Governance,Banks&Banking Reform

    The experience of accommodating privacy restrictions during implementation of a large-scale surveillance study of an osteoporosis medication.

    PurposeTo explore whether privacy restrictions developed to protect patients have complicated research within a 15-year surveillance study conducted with US cancer registries.MethodsData from enrolling 27 cancer registries over a 10-year period were examined to describe the amount of time needed to obtain study approval. We also analyzed the proportion of patients that completed a research interview out of the total reported by the registries and examined factors thought to influence this measure.ResultsThe average length of the research review process from submission to approval of the research was 7 months (range, <1 to 24 months), and it took 6 months or more to obtain approval of the research at 41% of the cancer registries. Most registries (78%) required additional permission steps to gain access to patients for research. After adjustment for covariates, the interview response proportion was 110% greater (ratio of response proportion = 2.1; 95% confidence interval: 1.3, 3.3) when the least restrictive versus the most restrictive permission steps were required. An interview was more often completed for patients (or proxies) if patients were alive, within a year of being diagnosed, or identified earlier in the study.ConclusionsLengthy research review processes increased the time between diagnosis and provision of patient information to the researcher. Requiring physician permission for access to patients was associated with lower subject participation. A single national point of entry for use of cancer registry data in health research is worthy of consideration to make the research approval process efficient. © 2016 The Authors.

    A mathematical model for bone marrow donors' registries and cord blood banks

    Get PDF
    This paper constructs an economic analysis of some organ donation organizations. The two main examples are voluntary marrow donor registries and cord blood banks. The main characteristic of this system is to facilitate the graft of bone marrow or cord blood to patients. These grafts require a high degree of compatibility between donors and receivers and the efficiency of this system is not always satisfactory despite sizes of the registries. This paper gives a framework to understand the key parameters of this problem and to proceed to simulations. We consider the case without screening or the case of optimal selection. These models may be used to infer an economic evaluation of the registries and of cord blood banks.

    Institutional support of the firm: A theory of business registries

    Get PDF
    Registering originative business contracts allows entrepreneurs and creditors to choose, and courts to enforce market-friendly “contract” rules that protect innocent third parties when adjudicating disputes on subsequent contracts. This reduces information asymmetry for third parties, which enhances impersonal trade. It does so without seriously weakening property rights, because it is rightholders who choose or activate the legal rules and can, therefore, minimize the cost of any possible weakening. Registries are essential not only to make the chosen rules public but to ensure rightholders’ commitment and avoid rule-gaming, because independent registries make rightholders’ choices verifiable by courts. The theory is supported by comparative and historical analyses.property rights, theory of the firm, business registries, formalization, starting a business, impersonal transactions.

    An overall strategy based on regression models to estimate relative survival and model the effects of prognostic factors in cancer survival studies.

    Relative survival provides a measure of the proportion of patients dying from the disease under study without requiring the knowledge of the cause of death. We propose an overall strategy based on regression models to estimate the relative survival and model the effects of potential prognostic factors. The baseline hazard was modelled until 10 years follow-up using parametric continuous functions. Six models including cubic regression splines were considered and the Akaike Information Criterion was used to select the final model. This approach yielded smooth and reliable estimates of mortality hazard and allowed us to deal with sparse data taking into account all the available information. Splines were also used to model simultaneously non-linear effects of continuous covariates and time-dependent hazard ratios. This led to a graphical representation of the hazard ratio that can be useful for clinical interpretation. Estimates of these models were obtained by likelihood maximization. We showed that these estimates could be also obtained using standard algorithms for Poisson regression
