Psychology of computer use: XLII. Problem solving and humor as a function of computer anxiety.

From a pool of 115 undergraduate women, 20 were placed in a Computer-anxious group and 20 in a Computer-nonanxious group based on their scores on the Computer Anxiety Scale. Half of the subjects were randomly assigned to a group to which the computer presented the problems first and half to a group to whom the computer presented the jokes first. Electromyograms from subjects' zygomatic muscles were monitored as well as palmar skin conductance. Behavioral measures were collected prior to and following the computer interaction. Although the electromyogram for zygomatic tension (smiles) was higher in the jokes condition, indicating that subjects responded to jokes as humorous, Computer-anxious subjects showed increased scores on anxiety and depression and relatively high skin conductance on the initial joke. Subjects with high computer-anxiety had less experience with computers, had lower scores on the Rosenberg Self-esteem test, and, likely not being familiar with computer humor, reacted anxiously.

Use of MEDLINE by physicians for clinical problem solving.

OBJECTIVE: To understand the ways in which computer-mediated searching of the biomedical literature affects patient care and other professional activities. Undertaken to determine the ways in which on-line access to the biomedical literature via the National Library of Medicine's MEDLINE database "makes a difference" in what physicians do when confronted with a medical problem requiring new or additional information. DESIGN: An adaptation of the Critical Incident Technique used to gather detailed reports of MEDLINE search results that were especially helpful (or not helpful) in carrying out the individual's professional activities. The individual physician was the source of the patient care incident reports. One thousand one hundred fifty-eight reports were systematically analyzed from three different perspectives: (1) why the information was sought; (2) the effect of having (or not having) the needed information on professional decisions and actions; and (3) the outcome of the search. PARTICIPANTS AND SETTING: Telephone interviews were carried out with a purposive sample of 552 physicians, scientists, and other professionals working in a variety of clinical care and other settings. Of these, 65% were direct users of MEDLINE throughout the United States, and 35% had MEDLINE searches conducted for them either at a major health sciences center or in community hospitals. RESULTS: Three comprehensive and detailed inventories that describe the motivation for the searches, how search results affected the actions and decisions of the individual who initiated the search, and how they affected the outcome of the situation that motivated the search. CONCLUSIONS: MEDLINE searches are being carried out by and for physicians to meet a wide diversity of clinical information needs. Physicians report that in situations involving individual patients, rapid access to the biomedical literature via MEDLINE is at times critical to sound patient care and favorably influences patient outcomes.

Evidence based medicine: an approach to clinical problem-solving.

Doctors within the NHS are confronting major changes at work. While we endeavour to improve the quality of health care, junior doctors' hours have been reduced and the emphasis on continuing medical education has increased. We are confronted by a growing body of information, much of it invalid or irrelevant to clinical practice. This article discusses evidence based medicine, a process of turning clinical problems into questions and then systematically locating, appraising, and using contemporaneous research findings as the basis for clinical decisions. The computerisation of bibliographies and the development of software that permits the rapid location of relevant evidence have made it easier for busy clinicians to make best use of the published literature. Critical appraisal can be used to determine the validity and applicability of the evidence, which is then used to inform clinical decisions. Evidence based medicine can be taught to, and practised by, clinicians at all levels of seniority and can be used to close the gulf between good clinical research and clinical practice. In addition it can help to promote self directed learning and teamwork and produce faster and better doctors.
