Computer-assisted learning in the teaching of anaesthesia.

A comparison of computer-assisted learning and small tutorial group teaching was carried out in the instruction of final year medical students in anaesthesia. The scores attained by fifteen of the sixteen students were higher after computer-assisted learning than after small group teaching. Statistical analyses of the results demonstrated that in this study computer-assisted learning was significantly better than small tutorial teaching.

Attitudes of medical undergraduates in Glasgow to computer-assisted learning.

Computer-assisted learning (CAL) has been introduced as part of the undergraduate teaching course in general practice during the penultimate year of the medical course. The student is given an opportunity to make clinical decisions and to manage a case over a significant time scale. The attitudes of the students are favourable to this method of instruction.

Quality assessment and the art of medicine: the anatomy of laceration care.

Assuring high quality medical care has remained an elusive goal because of several problems which have hampered development of effective medical audit programs: inadequate patient data, unreasonable evaluative criteria and insensitive audit procedures. The present study demonstrates the use of a clinical algorithm to help overcome these problems. An examination of medical record data from a series of 703 laceration patients treated in an emergency service yielded only 27 cases (4 per cent) with medical records sufficiently complete to use for auditing physician compliance with algorithmic criteria. Substituting a structured checklist for the handwritten note increased this rate to 86 per cent. A computer-assisted branching audit of 1,400 laceration cases demonstrated that 1) physician compliance with an algorithmic instruction varied significantly (p less than .001) according to the specific instruction, and 2) compliance with a given instruction varied significantly (p less than .001) across different providers. These results underscore the need for medical audit with educational feedback which is provider specific.

Cardiovascular phase relationships to the cortical event-related potential of schizophrenic, depressed, and normal subjects.

Cardiovascular phase, especially diastole, influences attention and the event-related potential (ERP) of the right hemisphere of the brain. Depression and schizophrenia are characterized by attentional deficits, unique lateralization of brain function, and deviant phase relationships of biological oscillators. In the present study, the ERP was recorded during stimulation triggered by diastole and systole in control (n = 16), depressed (n = 16), and schizophrenic (n = 9) subjects. Fifty tones were presented and subjects were instructed to count them silently. Previous findings were supported of delayed latencies and increased amplitude in depressed patients and decreased amplitudes and delayed latencies in schizophrenics. An exaggerated effect of diastole on the ERP in the right hemisphere was observed in depressed patients, however, no cardiovascular effect on the ERP was apparent in schizophrenic patients. Results suggested that heart/brain networks are tightly coupled in normal controls, perhaps "overdriven" in depressed patients, and uncoupled in schizophrenics.

Masticatory muscle fatigue: endurance times and spectral changes in the electromyogram during the production of sustained bite forces.

The purpose of this experiment was to determine if the characteristics of fatigue observed in the limb muscle system are also evident in the muscles of mastication, specifically, the masseter and temporalis. Surface electrodes were placed bilaterally over the masseter and temporalis muscles of 10 adults. Each subject was instructed to maintain maximal and six levels of submaximal incisal bite forces for as long as possible. The power density spectrum of the electromyographic signals for each muscle was calculated at the onset and failure of the task. The decrease in endurance time with an increase in bite force followed a pattern similar to that in limb muscles, and each muscle was characterized by a consistent reduction in the mean power frequency of the power density spectrum and a variable change in r.m.s. power. The variability of changes in r.m.s. power (which is inconsistent with changes found in the limb muscles) was explained in terms of either changes in motor-unit firing rate or the muscle's relative contribution to the generation of bite force. The analyses also demonstrated a curvilinear relationship between bite force and r.m.s. power, but no relationship between bite force and the mean power frequency of the power density spectrum.

Roentgen-tele-data: a radiodiagnostic recording system.

A radiodiagnostic data-handling system with telephones connected to the hospital exchange is described. Time, date, and location of examination are automatically recorded. The system can deliver spoken instructions from the computer and warns if data are not valid. Diagnosis, their degree of verification, and cases of special interest are added at display terminals. Codes, equipment, and output are described. Costs represent 1% of the department's expenditures. Future plans include a booking sytem, rapid access, and on-line connection to the main data system.
