Microcomputers have great potential in therapeutic environments, but, if they are to achieve this potential, they need appropriate software (programs). This paper examines the ideas behind games software and the relevance of commercially available software to therapy. It recommends that specially designed programs are needed and lays down some guidelines for the design and development of such software.
SAPHIRE (Semantic and Probabilistic Heuristic Information Retrieval Environment) is an experimental computer program designed to test new techniques in automated information retrieval in the biomedical domain. A main feature of the program is a concept-finding algorithm that processes free text to find canonical concepts. The algorithm is designed to handle a wide variety of synonyms and convert them to canonical form. This allows natural language to be used for query input and also serves as the basis for a new approach to automatic indexing based on a combination of probabilistic and linguistic methods.
Unlike test sensitivity and specificity, the false positive and negative predictive values (probabilities of mislabeling an individual being tested) depend heavily on the prevalence of the infection of the human immunodeficiency virus (HIV) as well as the quality of the kit. A consequence of this dependence is that the false positive predictive value can reach a high magnitude such as 0.9; that is, 90% of the positive tests are false. This raises many important issues pertaining to the current practice of HIV screening such as to how to control these misclassification errors, how to interpret test results, and how to estimate prevalence using test results. These issues are examined in detail here by considering the factors that dictate the quality of a screening program. Some real data examples are used to illustrate the importance of this consideration in designing programs to achieve the desired goals. The rationale behind the common two-step sequential protocol in HIV screening is examined to point out its limitations under practical situations. Finally, the use of entropy in evaluating the informativeness of a screening program is discussed.
An analysis was made of 18,804 of 19,446 consecutive births of the number analysed 15.93% presented low birth-rate. Significant statistical association was found in relation to maternal age, pre-natal care, previous pregnancies, smoking and gestational age at birth. Measures with a view to the attenuation of the problem are proposed, among them being: educational programs for teenagers on human reproduction, programs designed to create awareness of the harm done by smoking, amplification of antenatal assistance, medical programs for the limitation of premature labor, all of these and others, in association with programs of socio-economic support.
This national survey of Fellows of The American College of Obstetricians and Gynecologists found that obstetrician/gynecologists are actively involved in continuing medical education activities and appear satisfied with the resources available, yet desire additional opportunities for lifelong learning. Traditional resources (eg, journals, seminars) are used much more extensively than newer, electronic resources (eg, video cassettes, cable television), probably as a result of unfamiliarity with these latter methods and limited access to them. However, the majority of Fellows want increased exposure to these newer educational programs. Relevance of content, caliber of faculty, and potential for professional growth were important factors in choosing continuing medical education programs. Strong interest was expressed in individualized learning programs designed in collaboration with university faculty. These findings are of value in producing future educational programs for practitioners in obstetrics and gynecology.
Nurses have the clinical expertise that enables them to better understand the complex issues inherent in management of the delivery of health care. Yet without adequate preparation in management, as well as training of higher levels of nursing theory and research, nurses will be less prepared to compete at higher levels as the system continues to change. The University of Colorado offers a program designed to meet these needs, which serves as a national model for other schools of nursing considering such a curricular change. Further research needs to be conducted to identify the specific components of a graduate program that will enable the nurse executive to develop advanced nursing practice skills while developing the management skills necessary to achieve effectiveness in the practice setting. Because the long-term outcome of the dual degree model is still unknown, the effectiveness of the program in the health care system over time will be evaluated in relation to three outcomes: first, the effectiveness of program goals and objectives for producing successful nurse executives; second, the effectiveness of the curriculum design in preparing successful nurse executives; and third, satisfaction of graduates with the program and with their preparation. Participants in the dual degree program look forward to meeting this challenge.
Meeting the health needs of patients and providing comphrehensive health care services require the integration and coordination of several professional health services. Traditional methods for training students in the health professions independently are being challenged by the need for future practitioners to understand and to utilize effectively the skills offered by the other disciplines. However, the movement of educational institutions toward interdisciplinary training programs entails the careful assessment of program design, content, and basic philosophy. Two and one-half years of experience with such a program at one academic health center are reviewed.
OBJECTIVE: To assess current practices and attitudes toward teaching humanistic and psychosocial aspects of care in internal medicine residency programs. DESIGN AND PARTICIPANTS: Survey questionnaires were sent to residency directors at all 434 internal medicine residency programs accredited in 1985-1986. Response rate for two mailings was 71%. MEASUREMENTS AND MAIN RESULTS: 78% OF RESIDENCY DIRECTORS and 70% of department chairpersons had high or moderately high levels of commitment to teaching humanistic/psychosocial aspects of care, but only 44% of responding programs offered mandatory training, and only 18% offered elective training in these areas. Obstacles to expanded teaching of the humanistic/psychosocial aspects rated high or moderately high by residency directors included insufficient curriculum time (51%), lack of trained faculty (44%), and pressures to reduce both training costs (40%) and patient-care costs (37%). CONCLUSIONS: Most of the training that does occur in the humanistic/psychosocial aspects of care probably happens informally via mentoring and role modeling. Appeals to expand teaching in these areas raise questions regarding what to include in medical training and the proper scope of internal medicine. Sustainable change will depend on the politics of resource distribution and the influence of general internal medicine and primary care on traditional training.
Ten of the original 24 factories from the United Kingdom Heart Disease Prevention Project were resurveyed in 1983 to assess the long-term (12-year) effects of an education program on diet, smoking, and exercise. These 10 factories had previously been grouped into five pairs matched for size, location, and nature of industry, with one of each pair randomly chosen for intervention. Men in intervention factories were given advice on reduction of cholesterol in diet, stopping smoking, weight reduction, and regular exercise. High-risk workers (13%) received personal counseling in addition to the factory-wide education program. A total of 1,204 workers randomly selected from those still employed in 1978 were surveyed. There were significant differences observed in cigarette consumption, butter use, and several other dietary behaviors; however, the differences were small and insignificant for the proportion smoking and leisure-time exercise. The largest effects were in the high-risk group who had received personal counseling. This education program appears to have some lasting effects on behavior associated with coronary disease risk factors. Similarly designed programs may serve as models for community-wide coronary disease prevention programs.
This survey assessed the status of Wisconsin public school district programs designed to prevent alcohol and other drug related problems among students. The assessment involved surveying prevention program directors of 102 school districts that received grants for prevention initiatives since 1981. Most districts (70%) implemented programs at the elementary, middle, and senior high school levels. Typical program strategies involved combining information dissemination with refusal skill and self-concept development. School programs predominantly were school-based and did not systematically involve community members or agencies. The greatest obstacles to providing effective prevention services include high rates of alcohol and other drug use in homes and communities, denial of alcohol and other drug related problems among students, parents, and community members, and lack of staff time for prevention activities. Project directors indicated a need for schools to initiate greater involvement of parents, nonschool alcohol and drug abuse prevention agencies, and other community organizations in school efforts.
Non-insulin-dependent diabetes mellitus (NIDDM) is a serious health problem among the Zuni Indians of New Mexico. In July 1983, Indian Health Service personnel initiated a community-based exercise program designed to help control NIDDM in the community. To retrospectively evaluate the effects of the exercise program, the medical records of 30 participants with NIDDM were compared with the medical records of 56 nonparticipants with NIDDM matched by age, sex, health-care provider, and duration of NIDDM. From 1 July 1983 through 1 October 1985, participants had a mean weight loss of 4 kg, whereas nonparticipants had a mean weight loss of 0.9 kg (P less than .05). Participants' fasting blood glucose values dropped by a mean of 43 mg/dl, compared to a mean drop of 2 mg/dl among the nonparticipants (P less than .05). Participants were significantly more likely than nonparticipants to have stopped their hypoglycemic medication (relative risk 4.2) and to have decreased their medication dosage (relative risk 2.2). These results suggest that participation in a community-based exercise program can produce significant weight loss and improvement in glycemic control among a group of Native Americans with NIDDM.
We describe a set of IBM-compatible computer programs designed to selectively identify the potential sites for silent mutagenesis within a target DNA sequence. This program is based on a novel strategy of identifying amino acid motifs compatible with each restriction site (BioTechniques 12:382-384, 1991). The programs can be used to identify the suitability for the introduction of any 6-base nucleic acid sequences, such as restriction enzyme sites in cassette mutagenesis strategies. The Table program generates a table of multiple amino acid motifs for each restriction enzyme, obtained by translating each unique recognition sequence in all three reading frames. The Silmut program, which utilizes the features of Table, will further identify the presence of a match between any amino acid motif of each restriction enzyme and the input target sequence. Minor manipulations of the data base files will enable the individual researcher to identify the potential for introduction of any 6-base sequences by silent mutagenesis.
A study was designed and implemented between 1983 and 1985 in order to evaluate the effectiveness of a personalized health education program designed for pregnant women in the specific context of rural areas. The action succeeded in increasing the proportion of women benefiting from a monthly antenatal surveillance but many other results underline the limitations of such prevention programs that would be restricted to the information of the general public and health professionals. Perinatal morbidity in the north-alpine rural area ranks very favourably compared to the regional or national figures.
The Instrumental Enrichment program, designed to modify the cognitive structures of retarded, disadvantaged adolescents, was contrasted with a General Enrichment program both in a residential setting and a day center. This study is based on 57 matched pairs drawn from the total research sample of 218 adolescents. One group in a residential center (n = 24) and one group in a day center (n = 33) received Instrumental Enrichment; one group in a residential center (n = 24) and one group in a day center (n = 33) received General Enrichment. The Instrumental Enrichment program extended over 2 years, and the subjects were pre- and posttested on a battery of criterion measures: general and specific cognitive tests, scholastic achievement, classroom interaction, and self-concept. The results indicated significantly better performance by the groups receiving Instrumental Enrichment than by the groups receiving General Enrichment on the tests of specific cognitive functions and scholastic achievement and on some of the classroom interaction scales. Results for the residential groups compared with the day-center groups revealed significant differences on the tests of scholastic achievement, in favor of the residential groups and on the classroom interaction scales in favor of the day-center groups.
As continuing education programs for radiologic technologists expand, it is important that needs be properly assessed and well-designed programs be developed. This reports on the step-by-step process of a regional medical education center to provide continuing education for technologists that would be most beneficial to them and indirectly to the patients they serve.
Case management and quality assurance techniques were used in a program designed to improve the process and outcomes of care for inner-city children with asthma. The program had three major elements: assessment of the care of individual patients and feedback to their primary care providers, periodic contact with parents, and provision of educational materials about asthma to parents. Telephone interviews with parents were used to assess knowledge of home asthma care and the type of care prescribed by the child's physician. Medicaid and hospital records were used to measure acute care utilization. Eighty-eight children (aged 0 to 5 years) who had made more than two emergency room visits for asthma were recruited by telephone. Fifty-six prescribing errors were identified, 24 being failure to prescribe an additional drug for short-term use by children receiving continuous therapy. Acute care use dropped 50% compared with a control period. This type of program is feasible but may require in-person recruiting to reach high-risk families without telephones.
The purpose and the operation of an effective helping service are defined along the principles developed by R. R. Carkhuff. A functional operationalism directly linking each aspect of a helping service to the objective of servicing the needs of those people for whom the service exists is developed. The personal fitness of the staff as defined by their effectiveness at living is identified as the critical variable determining service effectiveness. The level of staff performance on the operational indices of physical, emotional, and intellectual functioning including, specifically, the interpersonal dimensions of empathy, respect, genuineness, concreteness, confrontation, and immediacy is designated as the operational basis for the organizational decisions of hiring, firing, promotion, and role assignment. Systematic programs designed to meet specific client needs serve to complete staff and service effectiveness.
The Pawtucket Heart Health Program, a research effort testing a process of community activation for cardiovascular risk factor behavior change, risk factor change, and coronary heart disease event rate change, utilizes risk factor behavior change programs for the entire population of a northeastern city. A diversity of nutrition programs designed to teach new skills and to alter the nutrition environment have been delivered. These include group programs, highlighting restaurant menus, labeling grocery shelf items, screening for blood cholesterol levels accompanied by nutritional counseling, and provision of programs in schools. In addition to standard curricula, the Heart Healthy Cook-Off for both junior high school and high school students has been developed. Students select recipes, make substitutions to lower fat, saturated fat, and cholesterol content, analyze original and substitution recipe nutrient content using a microcomputer and nutrient analysis software, and prepare the food. A panel of judges assesses presentation, taste, and health-promoting characteristics. In one junior high school class, cholesterol measure before and after the cook-off decreased by 10.7% among those with elevated cholesterol. The Heart Healthy Cook-Off is an education program that influences the culinary practices of children in an enjoyable, challenging format.
