BACKGROUND: Tissue Microarrays (TMAs) allow researchers to examine hundreds of small tissue samples on a single glass slide. The information held in a single TMA slide may easily involve Gigabytes of data. To benefit from TMA technology, the scientific community needs an open source TMA data exchange specification that will convey all of the data in a TMA experiment in a format that is understandable to both humans and computers. A data exchange specification for TMAs allows researchers to submit their data to journals and to public data repositories and to share or merge data from different laboratories. In May 2001, the Association of Pathology Informatics (API) hosted the first in a series of four workshops, co-sponsored by the National Cancer Institute, to develop an open, community-supported TMA data exchange specification. METHODS: A draft tissue microarray data exchange specification was developed through workshop meetings. The first workshop confirmed community support for the effort and urged the creation of an open XML-based specification. This was to evolve in steps with approval for each step coming from the stakeholders in the user community during open workshops. By the fourth workshop, held October, 2002, a set of Common Data Elements (CDEs) was established as well as a basic strategy for organizing TMA data in self-describing XML documents. RESULTS: The TMA data exchange specification is a well-formed XML document with four required sections: 1) Header, containing the specification Dublin Core identifiers, 2) Block, describing the paraffin-embedded array of tissues, 3)Slide, describing the glass slides produced from the Block, and 4) Core, containing all data related to the individual tissue samples contained in the array. Eighty CDEs, conforming to the ISO-11179 specification for data elements constitute XML tags used in the TMA data exchange specification. A set of six simple semantic rules describe the complete data exchange specification. Anyone using the data exchange specification can validate their TMA files using a software implementation written in Perl and distributed as a supplemental file with this publication. CONCLUSION: The TMA data exchange specification is now available in a draft form with community-approved Common Data Elements and a community-approved general file format and data structure. The specification can be freely used by the scientific community. Efforts sponsored by the Association for Pathology Informatics to refine the draft TMA data exchange specification are expected to continue for at least two more years. The interested public is invited to participate in these open efforts. Information on future workshops will be posted at http://www.pathologyinformatics.org (API we site).
OBJECTIVE: To determine the characteristics of community-based musculoskeletal services provided by primary care organizations within the UK. METHODS: Members of five professional groups within UK primary care organizations (n=461) were sent a questionnaire. RESULTS: The response rate by organization was 71% (328/461). Respondents described 350 community-based musculoskeletal services, 233/328 (71%) organizations had one or more musculoskeletal services within their community. Five main forms of service provision were: a scanning service, a rehabilitation service, physiotherapy services, joint or soft tissue injections and the implementation of integrated care pathways. In 162 services, patients were assessed, reviewed or triaged, by a 'non-consultant' health-care professional (physiotherapist or general practitioner), at an intermediate level between primary and secondary care. The purpose of the service was described in 292/350 services, only 39/350 had clear evaluation strategies and 53/350 had consideration of individual training needs. CONCLUSIONS: There are a wide range of musculoskeletal services flourishing within the community sector, whose quality may be variable. Whilst there is good evidence to suggest systematic planning of these services, we are concerned about the lack of data to support their effectiveness in terms of clinical outcomes, monitoring of service delivery standards and ongoing professional development of service providers. Commissioners of such services must ensure they have taken account of the evidence base and met any identified needs of local populations. Services should have a clear purpose with an appropriate evaluation strategy, and well-defined dissemination mechanisms. An integrated educational strategy for staff within the service must be sensitive to issues relating to accreditation, appraisal and revalidation.
