A COSTAR interface using WWW technology.

The concentration of industry on modern relational databases has left many nonrelational and proprietary databases without support for integration with new technologies. Emerging interface tools and data-access methodologies can be applied with difficulty to medical record systems which have proprietary data representation. Users of such medical record systems usually must access the clinical content of such record systems with keyboard-intensive and time-consuming interfaces. COSTAR is a legacy ambulatory medical record system developed over 25 years ago that is still popular and extensively used at the Massachusetts General Hospital. We define a model for using middle layer services to extract and cache data from non-relational databases, and present an intuitive World-Wide Web interface to COSTAR. This model has been implemented and successfully piloted in the Internal Medicine Associates at Massachusetts General Hospital.

Experiences in deployment of a Web-based CIS for referring physicians.

Improving the timeliness and efficiency of information exchange between the hospital and clinicians in the health care community is an area of active interest at the Massachusetts General Hospital (MGH). Providing computer-based access to referring physicians who are not formally affiliated with the hospital is a particular challenge since these offices are not connected to the hospital network and lack the standard hospital workstation hardware and software. Installing clients for the hospital's clinical applications at these sites has been a difficult and costly proposition. The emergence of Web technology yields an alternative method for developing clinical applications for this remote, diverse user population. We present our experiences during the first six months of deployment of a Web-based clinical information system designed for use by referring physicians.

Assessing goodness-of-fit of parametric regression models for lifetime data-graphical methods.

Graphical methods are often used to check goodness-of-fit of models to data. It is common to plot residuals against a reference distribution so that when the model fits the data, the configuration should be close to a straight line. Since the resemblance to a straight line is often unclear, it has been suggested to add simulated envelopes within which the configuration is expected to lie. The implementation of this method for survival data analysis is not straightforward. In this paper we point out the difficulties which arise in constructing envelopes on residual plots for randomly censored data. Methods are suggested to deal with the problems and evaluated; they are illustrated by simulated data and on a follow-up study of myeloma.

Evaluation of a problem-based access knowledge system using triangulation methods.

A microcomputer-based system designed to provide nurses and physicians access to expert synthesized knowledge in the area of pulmonary arterial waveform troubleshooting has been developed and implemented. Evaluation using triangulation methods show that there was a substantive increase in knowledge in both nurses and physicians.¿.

Nonprofessionals in the rehabilitation of mentally disordered sex offenders.

Eighty-six sex offenders were exposed to a 6-month voluntary program of either group encounters (experimental group) or hobbies and games (control group) led by nonprofessionals. Pre- and posttests included a personality test, an introspective report, and a behavior rating scale. Written ward records were assessed as were the results of a postexperimental prisoner evaluation of the experience. Significant changes were evidenced by encounter subjects in improved feelings of approval of the prison-hospital experience, lessened hostility, and better attendance at the meetings. Encounter subjects were improved in the predicted direction on 55 of the 74 treatment dimensions. Community volunteers were judged moderately successful as lay therapists.

A criminal offender introspective report.

The development of a new scale suitable for research with the criminal offender was described. Based on the factor analysis of an item pool delineating sociopathic personality traits, five factors were derived to compose an 80-item criminal offender introspective report (COIR).
