An assessment of discharge planning models: communication in referrals for home care.

A home care referral generated upon hospital discharge communicates essential patient care information, links service providers, and facilitates continuity of patient care. The literature however, reveals that communication efforts are often inadequate and may even fail in this system. The purpose of this research was to examine whether various discharge planning models employed by hospitals resulted in differences in the quantity and quality of communication about patients referred for home health care. Kelly and McClelland's (1985) typology of discharge planning models provided the framework for the study. Using instruments designed specifically for this project, six referring hospitals' functional discharge planning models were labeled and 300 closed home care records of referrals were reviewed to ascertain the amount and type of data transmitted. Results indicated that only slightly more than half of the data recommended by the literature was actually transferred and that data was primarily background in nature. The hospital discharge planning model did make a significant difference in the amount and type of data shared, with liaison nurses sending the greatest amount of data. However, both conceptually and in practice, the discharge planning models simply describe an allocation of responsibility among various health personnel. They are not operational models in the traditional sense.

An evaluation of the applicability of quantitative clinical standards for the management of genital chlamydial infection using an electronic database.

A prototype electronic database was designed for use as a retrospective audit tool to provide data that allowed comparison of genital chlamydial infection management performance with a series of quantitative operational consensus standards. However, some of the terms used by the standards require further definition for translation into database fields to improve accuracy and general application as an audit tool. Construction of the database involved differentiation between prior and clinic diagnostic points, as well as a forward contact trail of specific quantitative indicators of contact tracing. More definition is needed of the meaning of diagnosis and contact in the standards. For clinic-diagnosed patients, the time to treatment was mainly dependent on clinical factors, not on the availability of a chlamydial test result. For about one-third of patients (with prior management), several standards cannot be applied because data are not available, and this raises the issue of data sharing between various agencies involved in chlamydial testing. More data from other clinics may help both to test the appropriateness of, and inform, some of the operational standards. The database could be developed as a real-time audit tool for use with electronic patient records.

Genetic analyses of focal aspects of infant temperament.

The authors explored the genetic and environmental underpinnings of individual differences in temperament with a sample of 604 3- to 16-month-old infant twins and their parents. Mothers completed Rothbart's Infant Behavior Questionnaire (IBQ), and a subsample of 140 9-month-old twins participated in behavioral assessment of temperament in the laboratory as well. For IBQ Smiling and Laughter and Duration of Orienting, both additive genetic and shared environmental effects were needed to best represent the data. Shared environmental effects fully accounted for cotwin similarity for IBQ Soothability, and conversely, additive genetic effects fully accounted for cotwin similarity for the IBQ Distress to Limitations, Distress to Novelty, and Activity Level scales. With the subsample, the authors fit a multivariate model to mother report, father report, and lab measures of stranger distress and found that genetic influences were most important for the covariation among these measures.

Methods for assessing rat sperm motility.

Computer-assisted sperm analysis (CASA) systems are becoming more widely used. With this spread of technology come more data from toxicology studies, designed to determine if treatment with putative toxicants affects sperm motion parameters. While these CASA methods provide us with more ways to evaluate toxicity and thus perhaps increase our chances of successfully protecting human health, there is also a greater likelihood that different laboratories will use different methods of collecting data on sperm motility. Different systems used with different methods in different laboratories will inevitably generate data that are difficult to compare. In a prospective attempt to address this issue of comparability and limit the problems, a group of individuals using CASA systems to analyze rat sperm motility convened to discuss methodologic issues, share data, and try to reach a consensus about methods for performing these studies. This article shares those meetings and data in the hope that common methods will enhance interlaboratory comparisons.

The challenge of documenting managed care cost savings and performance.

It is not too late for managed care to turn this situation around because the debate over health care reform and managing change is ongoing. It remains to be seen whether managed care companies will support independent third parties (i.e., researchers) in analyzing proprietary data and making value judgments about their effectiveness. There is a perception among managed care organizations that potentially negative findings could damage them in the marketplace. Nonetheless, smart organizations use negative findings as new opportunity targets for service improvement and product refinement. To what extent will managed care companies voluntarily release accurate data on performance factors in order for researchers to conduct cross-company analyses? Perhaps competitive markets such as managed care are not consistent with voluntary data sharing. On the other hand, mandatory reporting will not ensure data accuracy either. It is up to the managed care industry itself to develop a cooperative approach to data collection, analysis, and dissemination.

Management factors associated with swine breeding-herd productivity in the United States.

A database containing 24 key production measurements was created by abstracting data files of 673 U.S. farms which participated in the PigCHAMP data-share program in 1995. Summary statistics for breeding-herd performance data were presented for the Cornbelt and the South or Eastern regions. Eight models were built to assess the association between production system, operation management factors and productivity outcomes. Lactation length, percentage of multiple matings, parity of culled sows, percent gilts in the breeding-female inventory, and female culling rate were the management factors identified as having important associations with productivity outcomes. For example, shorter lactation length, higher percentage of multiple matings, and lower culling rate were associated with more pigs weaned per mated female per year. In addition, a lower percentage of gilts in the breeding-female inventory and a higher percentage of multiple matings were associated with fewer average non-productive female days. We recommend that producers change their management systems to decrease lactation length, the percentage of gilts in the breeding-female inventory, and female culling rate, and increase percentage of multiple matings in order to improve breeding-herd productivity on swine farms.

State programs for pesticide residues in foods.

Two U.S. data collection and dissemination programs, FEEDCON and FOODCONTAM, are described. FEEDCON provides information on contamination levels in animal feeds of toxic chemical residues (pesticides, industrial chemicals, heavy metals, mycotoxins, natural plant toxins, salmonella, and therapeutic drug cross-contaminations). FEEDCON data are collected from approximately 40 state feed regulatory agencies, feed manufacturers, and related groups who subscribe ($100-$200 per year) to the program, which is sponsored by the Association of American Feed Control Officials. FOODCONTAM provides similar information, but is limited to pesticides, heavy metals and industrial chemicals (polychlorinated and polybrominated biphenyls, etc.) in human foods. Both programs have been developed and initiated under U.S. Food and Drug Administration contracts with the Mississippi State Chemical Laboratory. Program structures of both are outlined conceptually, and FOODCONTAM is described in detail. FOODCONTAM data-sharing program development is essentially complete, but expansion by incorporating FDA data with State Laboratory data is nearing reality.

Conceptual analysis for knowledge-base design.

Knowledge-base design requires a thorough analysis of the concepts to be represented. If the analysis is incomplete or inaccurate, the resulting knowledge base may contain arbitrary restrictions, inconsistent data, or limitations that make future extensions impossible. Conceptual analysis is even more critical for sharing knowledge bases between heterogeneous systems. Analyses that are adequate for independent systems may cause incompatibilities when the systems share data. This paper discusses the kinds of problems that require a careful conceptual analysis and the difficulties caused by an incorrect or incomplete analysis. It also shows how independently developed knowledge bases can be related to one another by reanalyzing and redefining the basic concepts and relations. Such analysis is essential for sharing knowledge between systems developed for different purposes, such as relational and object-oriented databases or expert systems and natural language processors.

Privacy-hardened and hallucination-resistant synthetic data generation with logic-solvers.

MOTIVATION: Machine-generated or synthetic data is a valuable resource for training artificial intelligence algorithms, evaluating rare workflows, and sharing data under stricter data legislations. However, current statistical and deep learning methods struggle with large data volumes, are prone to hallucinating scenarios incompatible with reality, and seldom quantify privacy meaningfully. RESULTS: Here, we introduce Genomator, a logic solving approach (SAT solving), which efficiently produces private and realistic representations of the original data. We demonstrate the method on genomic data, which arguably is the most complex and private information. We benchmark Genomator against state-of-the-art methodologies (Markov generation, Wasserstein Generative Adversarial Network and Conditional Restricted Boltzmann Machines), demonstrating a 40%-530% accuracy improvement and 57%-172% higher privacy. Genomator is also 3-100 times more efficient, making it the only tested method that scales to whole genomes. We show the universal trade-off between privacy and accuracy, and use Genomator's tuning capability to cater to all applications along the spectrum, from provable private representations of sensitive cohorts, to datasets with indistinguishable pharmacogenomic profiles. Demonstrating the production-scale generation of tuneable synthetic genomes hold great potential for balancing underrepresented populations in medical research and advancing global data exchange. AVAILABILITY AND IMPLEMENTATION: Genomator is available at https://github.com/csiro/genomator.

A biopsy of the use of the Baxter formula to resuscitate burns or do we do it like Charlie did it?

The Baxter formula is commonly used to calculate fluid requirements. Baxter reported that 12% of patients would require more than 4.3 mL/kg per percentage of total body surface area (%TBSA). We anecdotally observed that we frequently exceeded the predictions of the formula, and we wondered if this was unique to our practice. We studied our last 11 burn-related resuscitations and collected fluid resuscitation data from US burn centers. Twenty-eight centers were queried, and 6 centers shared data. We were therefore able to study the resuscitation data of 50 adult patients. For 29 patients (58%), 4.3 mL/kg/%TBSA was exceeded compared with the 12% reported by Baxter. These findings suggest that in actual practice, fluid volumes administered are larger than the Baxter formula predicts. This survey does not explain why. Possible reasons for the larger fluid volumes are as follows: (1) the sample is not representative; (2) the formula is used improperly; (3) burns have changed and require more fluids; (4) burn care has changed.

Representation of change in controlled medical terminologies.

Computer-based systems that support health care require large controlled terminologies to manage names and meanings of data elements. These terminologies are not static, because change in health care is inevitable. To share data and applications in health care, we need standards not only for terminologies and concept representation, but also for representing change. To develop a principled approach to managing change, we analyze the requirements of controlled medical terminologies and consider features that frame knowledge-representation systems have to offer. Based on our analysis, we present a concept model, a set of change operations, and a change-documentation model that may be appropriate for controlled terminologies in health care. We are currently implementing our modeling approach within a computational architecture.

A proposal for a standard CORBA interface for genome maps.

MOTIVATION: The scientific community urgently needs to standardize the exchange of biological data. This is helped by the use of a common protocol and the definition of shared data structures. We have based our standardization work on CORBA, a technology that has become a standard in the past years and allows interoperability between distributed objects. RESULTS: We have defined an IDL specification for genome maps and present it to the scientific community. We have implemented CORBA servers based on this IDL to distribute RHdb and HuGeMap maps. The IDL will co-evolve with the needs of the mapping community. AVAILABILITY: The standard IDL for genome maps is available at http:// corba.ebi.ac.uk/RHdb/EUCORBA/MapIDL.htm l. The IORs to browse maps from Infobiogen and EBI are at http://www.infobiogen.fr/services/Hugemap/IOR and http://corba.ebi.ac.uk/RHdb/EUCORBA/IOR CONTACT: manu@infobiogen.fr, tome@ebi.ac.uk

Secondary analysis: a method for learning research activities.

Secondary analysis may be an efficient, effective method of providing graduate students in nursing with experience in specified stages of the research process. The availability of archived data sets is increasing as are the numbers of researchers who recognize the value of sharing data with others. Thus, the development of nursing as a research-based practice can be enhanced by tapping into this source of data and asking relevant research questions that address issues in nursing.

SNOMED-based knowledge representation.

A standardized vocabulary and a standardized representation for this vocabulary are necessary prerequisites for the development of a computer-based patient record. A standard conceptual scheme or data structure for this vocabulary must be in place to define clinical events and to share data. SNOMED International is a detailed, fine grained, semantically typed and comprehensive computer processable vocabulary encompassing both human and veterinary medicine. Each term is placed in a standardized data structure that shows the term relationship within its own and other related taxonomic hierarchies. SNOMED International is a standardized vocabulary and data structure suitable for use in the computer-based patient record.

Etiological heterogeneity in Hodgkin's disease: HLA linked and unlinked determinants of susceptibility independent of histological concordance.

Forty-one multiplex families, from published sources and new data from the National Cancer Institute, segregating for Hodgkin's disease and HLA, have been studied. A reanalysis of these data strongly suggests a recessive mode of inheritance for susceptibility to Hodgkin's disease. The HLA haplotype sharing data between affected relatives demonstrate that approximately 60% of cases in multiplex families are due to an HLA-linked susceptibility gene, the remaining 40% being due to other familial factors. The data clearly support the hypothesis of etiological heterogeneity for Hodgkin's disease, with both HLA-linked and HLA-unlinked factors being responsible. Finally, there is an increased concordance of histological types between affected relatives, but this concordance seems independent of HLA sharing.

Using benchmarking data to evaluate and support pharmacy programs in health systems.

The use of benchmarking data to evaluate and support pharmacy programs in health systems is discussed. Benchmarking is a method of comparing the outcomes of health care products, services, and practices at an institution against those of competitors in order to learn what might be improved. Benchmarking programs can provide valuable feedback about both positive and negative outcomes. However, it is imperative to avoid inappropriate comparisons and inappropriate assessments. Ideal services for benchmarking are those that have a good likelihood of improving patient care and other outcomes. Successful benchmarking requires sound and thorough data, which is why as many health systems as possible should participate in a benchmarking program. The National Committee for Quality Assurance has formulated guidelines that should enable health systems to develop an information framework that will improve their ability to collect and use data for benchmarking. Standardization in collecting and submitting information is important because it enables institutions to share data easily. Benchmarking can help health-system pharmacists understand the value and outcomes of efforts by their colleagues at other institutions. In addition, benchmarking can help convince health-system administrators of the value of pharmaceutical services in terms of patient care and the bottom line. Benchmarking provides a means of evaluating and supporting the development of pharmacy programs that improve care and save money.

[Telematics equipment for poison control surveillance. Its applications in the health management of relevant chemical incidents].

Health management of major chemical incidents requires a close collaboration between rescuers (on the disaster site and in the emergency department) and the poison center. The study tested telematic technologies allowing telepresence and teleconsulting, a real time and continuous connection among health care personnel and toxicologists involved in the management of the emergency. The link between the poison center (PC) and the emergency department in the local hospital is provided by a ISDN operating video conferencing system, while the data transmission from the site of the accident to the PC is achieved with a personal computer and GSM cellular data transmission. Toxicological databases and risk assessment software are integrated in the system, to support information sharing. To test such instruments in operative nearly realistic conditions, the main phase of the study has implemented simulated chemical disasters in different locations in Italy. Instruments for telepresence and teleconsulting have been effectively utilized to evaluate from a remote location the scenario and the severity of the accident, by inspecting either specific details or the whole scene, to enable PC guiding the triage of the victims before and after hospitalization, to utilize and share data, such as intervention protocols or patient records, and to document all the activities. In summary, this experience shows that the telematic link allows the toxicologists of the poison center to rapidly understand the situation, and to correctly learn about the conditions of patients with the help of images. The results of this study indicate the valuable benefits of telematic instruments for the health care in case of major chemical disasters occurring in a remote geographical location or in an area which lacks local toxicological experts, where specialized expertise can be achieved by the use of telematic technologies.
