[Scientific knowledge and the methodologic problem of pain in medicine].

The paper discusses the epistemological question of pain and the way this concept forms part of scientific knowledge. The first part gives a rapid overview of the main aspects of modern scientific knowledge. In earlier times Bacon, Galileo and Descartes felt that the new form of knowledge could head to a knowledge of truth and certainty. Today, these ideals have proved unattainable and science only takes the form of well founded, rigorous and objective knowledge. Moreover, the objectivity of science is based on intersubjectivity. The second part of the paper examines pain and underlines that it is a subjective phenomenon which cannot be ascertained by the doctor in the same way as commonplace anatomic and physiological phenomena. Our scientific knowledge of pain is based on operations for which it is possible to achieve an intersubjective knowledge: these operations constitute the protocol criteria on which it is possible to base a scientific knowledge of pain. In the last part of this paper, having stressed that pain is a concept belonging to many disciplines--scientific, psychological, philosophical, religious--the emphasis is placed on pain itself as opposed to suffering. While the former is a concept that belongs to scientific medicine, the latter belongs to that area of medicine which lies beyond the boundaries of science and concerns the activity of a man who helps a fellow human who is suffering.

Longitudinal study of Finnish nursing students' preferences for knowledge in nursing practice.

The curriculum of Finnish nursing education is based on nursing science. The aim is to educate nursing students to internalize the logic, concepts and major subject areas of nursing science. The purpose of this longitudinal study was to examine Finnish nursing students' knowledge base of nursing after 6, 18 and 30 months of education and at the end of the degree programme. The study group consisted of 158 students selected by means of stratified sampling from the six specialities of Finnish nursing education programs. Data were collected by means of a questionnaire from 26 institutes. A factor analysis of 21 items was done, where three factors emerged. The summarized variables based on the factors were subjected to one-way analysis of variance to elucidate the differences between the six groups of students. The students prioritized biomedical knowledge. Knowledge of diseases and anatomy was preferred to the other knowledge areas. The students also valued psychological knowledge. Nursing knowledge was the least preferred knowledge area at every phase of education. The students of the different specialities preferred knowledge areas congruent with the nursing practice of their speciality.

Oral health knowledge, attitudes and preventive practices of third grade school children.

PURPOSE: The aim of study was to investigate the oral health knowledge, attitudes and preventive practices of third grade school children in Harris County. METHODS: In this cross-sectional study, oral health knowledge, attitudes, and preventive practices of the children were investigated by means of a self-administered, bilingual questionnaire. Three calibrated examiners collected data on dental caries, periodontitis, and fluorosis of 1,031 school children. RESULTS: Most children reported "fairly adequate" oral hygiene habits (58%) and oral health knowledge (48%), and "adequate" dietary patterns (59%). Children with inadequate oral health knowledge were twice as likely to have caries than children with adequate knowledge (OR = 2.05, 95% CI = 1.29, 3.28). The mean combined DMFT/dft scores of children with inadequate knowledge were significantly higher than the mean for children with adequate knowledge (t = 2.6, P = 0.009). CONCLUSIONS: Results indicate a need to improve oral health knowledge and preventive practices among the study population. Because of the cross-sectional nature of the study, it is not possible to illustrate a cause-effect relationship between oral health education and prevalence of caries.

Knowledge of disease and treatment among tuberculosis patients in Mwanza, Tanzania.

SETTING: A health care facility based study in a rural and urban setting in Mwanza region, Tanzania. OBJECTIVE: To determine patients' general knowledge of tuberculosis (TB) and the management of the disease. DESIGN: From 7 May to 7 July 1998, 296 pulmonary tuberculosis patients were consecutively interviewed. The majority of the respondents (89%) were outpatients. Questions were based on Tanzanian National Tuberculosis Programme (NTP) treatment guidelines for teaching tuberculosis patients. RESULTS: When correct answers to five out of seven questions asked was regarded as satisfactory knowledge, only 30% of the study population had satisfactory knowledge of disease and treatment. Persons with information on TB prior to diagnosis and those with higher education were more likely to have satisfactory knowledge (OR 9.23 and 19.93; 95%CI 2.77-31.08 and 5.74-69.19, respectively). There was a negative correlation between the level of knowledge and patients' age (-r = 0.181, P = 0.01). Knowledge was not significantly affected by sex or area of residence. The two most important sources of information about TB were health workers and former TB patients. CONCLUSIONS: Using NTP guidelines as reference, a substantial number of patients interviewed in health facilities in the study period had an unsatisfactory knowledge of TB disease and its management. The study did identify factors associated with satisfactory knowledge that could assist in designing health education intervention strategies.

Cross-sectional comparison of dental students' knowledge and attitudes before geriatric training: 1984-1999.

The existence of negative attitudes toward aging and a lack of factual information has been voiced in the dental and other health professions. With increasing numbers of elderly in society, intergenerational social contact is more likely to occur and has the potential to reduce negative attitudes and increase knowledge about aging. The purposes of this study were to determine if the level of intergenerational social contact of dental students in one dental school had changed over the last fifteen years and whether any such changes were related to shifts in students' baseline knowledge about aging and attitudes toward elderly patients. Dental students (n=269) representing three different cohorts were surveyed about intergenerational contact, knowledge about aging, and attitudes toward elderly patients prior to receiving any geriatric training. Overall, findings revealed little evidence of increasing intergenerational social contact, an actual decrease in knowledge, an increased negative bias in knowledge, and unchanged attitudes toward elderly patients over the past fifteen years. Recent students were more likely to have had grandparents living in the family home, to have slightly less correct factual knowledge, and to be more negatively biased in their incorrect factual knowledge than earlier students. There were no differences in attitudes toward elderly patients among cohorts. We concluded that additional research is needed to confirm or refute our trends on a national scope. Should these trends be confirmed, dental educators would be alerted to the continuing necessity of countering the students' potential negative biases as well as a lack of basic knowledge about aging.

High blood pressure knowledge in an urban African-American community.

OBJECTIVE: To determine the level and determinants of knowledge of the risks for hypertension and the potential for its prevention in an urban African-American community. METHODS: In a survey of 397 African-American adults (18-73 years of age) at an urban community fair, we measured high blood pressure knowledge using a 12-item questionnaire designed at NIH for the assessment of high blood pressure knowledge among non-medical persons. RESULTS: The mean high blood pressure knowledge score for the overall sample was 83.1%. There were subgroup differences in the scores with significant associations between high blood pressure knowledge score and level of education (P = .002) and a personal history of hypertension (P = .009). CONCLUSION: We concluded that the participants exhibited a high, but variable, level of high blood pressure knowledge with a higher level of education and/or a personal history of hypertension having a significant association with greater blood pressure knowledge. The effects of the magnitude and mode of acquisition of high blood pressure knowledge on the control of high blood pressure and its related outcomes need to be examined in further studies.

[Illness knowledge, social support and self care behavior in adolescents with beta-thalassemia major].

The purpose of this study was to explore the relationships among illness knowledge, social support and self-care behavior in adolescents with beta-thalassemia major. The subjects were 58 beta-thalassemia major adolescents recruited from the pediatric hematology outpatient departments of three hospitals in North Taiwan. All data were analyzed by descriptive statistics, one-way ANOVA, t-test, Pearson correlation, and stepwise multiple regression. The results showed that: (1) Scoring in illness knowledge, the best was treatment knowledge, and the worst was the knowledge of complications and symptoms. (2) The result for social support indicated that the family was the major source of support, and that classmates/friends provided the least support for thalassemic adolescents. (3) Scoring in self care behavior, the best was the medical and chelate therapy, and the worst was the management of problems and coping. (4) Individual characteristic differences, including sex, level of education, length of illness, complications of thalassemia, hospitalization due to thalassemic complications and receiving other treatments were correlated with their illness knowledge, social support or self-care behavior. (5) Illness knowledge, social support which were positively correlated with self-care behavior. (6) 50.0% of the variance in self-care behavior can be explained by emotional support from family, general knowledge of thalassemia, treatment knowledge and appraisal support from family. These findings could provide referential material for nursing research and nursing practice.

[Effects of health promotion for eight years on knowledge, attitude and behavior of cardiovascular diseases in rural Fangshan District, Beijing].

OBJECTIVE: To evaluate the effects of health promotion for eight years on cardiovascular diseases based on the changes in knowledge (K), attitude (A) and behavior (B) (KAB) before and after intervention in rural population of Fangshan, Beijing. METHODS: Five townships in Fangshan District, Beijing were divided into intervention and control communities with cluster sampling. Totally 772 farmers were selected randomly for interviews with a questionnaire of KAB, including 424 in the intervention communities (IC) and 348 in the control communities (CC) in 1992. After community-based health promotion and education on cardiovascular prevention for eight years, 895 farmers, including 431 in IC and 464 in CC, were selected randomly again in 1999 to be interviewed with the same questionnaire of KAB used in 1992. RESULTS: From 1992 to 1999, knowledge of cardiovascular diseases was significantly improved in residents of IC (P < 0.01) and CC. Compared to the residents in CC, there was a net increase in knowledge in residents of IC. Significant improvement was found in 10 and 11 of the 18 items of knowledge in males and females (P < 0.01), respectively. Level of knowledge in cardiovascular diseases was significantly higher in the residents of IC than those of CC in 1999. Proportions of those with positive attitudes and appropriate behaviors were significantly elevated in the residents of IC (P < 0.01), as well as prevalence of smoking and alcohol drinking decreased. However, as compared to CC, attitude and behavior in most aspects in the residents of IC changed positively, but in few aspects changed negatively. It suggested knowledge improved better than attitude and behavior changed. CONCLUSIONS: Community-based health promotion and education for a longer term had obvious effects on improvement of knowledge in cardiovascular disease for rural population, but slower effects on changes in attitude and behavior, which suggested there still existed certain barriers to transform knowledge into healthy behavior.

[Knowledge of contraception and sexual matters over the last 14 years. An investigation among 9th grade pupils in the municipality of Viborg].

INTRODUCTION: The aim of the investigation was to illustrate changes in the knowledge of ninth grade pupils about sexual matters over the last fourteen years. MATERIAL AND METHODS: Ninth grade pupils in schools in the municipality of Viborg answered a questionnaire about these subjects. Identical questionnaires were given to the same age group in 1986 and 1993. RESULTS: The pupils had less knowledge of contraception than earlier. The other questions about sexuality were answered as well as or better than previously. In 1986 and 1993, boys had less knowledge than girls, but this difference was now equalised. We found no connection between knowledge and age at first coitus or sexual habits, and no connection between knowledge and the sources from which the pupils gained their information. School was, as earlier, the most important source of information, but friends came a close second. Books, mother, and doctor or health visitor were often mentioned as important sources of sexual knowledge. As earlier, the pupils were not satisfied with the sex education and as earlier, they wanted more lessons and external teachers. DISCUSSION: A good knowledge of sexual matters does not mean better sexual habits. School is the most important source of knowledge and is even more important, because the young also educate friends, who are another main source of information. According to the pupils, sex education should be improved.

[Objective and subjective knowledge of HIV/AIDS as predictor of condom use in adolescents].

OBJECTIVE: To evaluate the association between objective and subjective knowledge on HIV/AIDS and condom use. MATERIAL AND METHODS: Analysis of a database from an anonymous, self-applied, randomized survey conducted between 1995 and 1996. Study subjects were 1,410 adolescents of four socioeconomic strata from Guadalajara, Mexico. Objective knowledge was assessed with 24 questions regarding HIV/AIDS, and subjective knowledge with the question "how much do you think you know about HIV/AIDS?" The variables associated with condom use were identified using logistic regression analysis and by calculating odds ratios with a 95% confidence interval. RESULTS: The degree of objective knowledge was "average", differentiated by socioeconomic strata (p < 0.001), and was higher in adolescents from medium and high socioeconomic strata (p < 0.008). Regarding subjective knowledge, adolescents from the low, medium, and high socioeconomic strata claimed to know "a little", and the ones from the lowest stratum claimed to know "very little". Condom use was higher in males (35.4%), and in adolescents from high socioeconomic strata (p < 0.005), than in females (15.3%) (p < 0.001). Although there was a correlation between objective and subjective knowledge (r = 0.37, p < 0.001), a higher degree of subjective knowledge was associated with condom use (p < 0.001). CONCLUSIONS: Subjective knowledge, belonging to medium and high socioeconomic strata and being male, were predictors of condom use.

The effect of education and clinical practice on knowledge enlightenment to and attitudes toward the use of analgesics for cancer pain among physicians and medical students.

BACKGROUND: Insufficient education and limited clinical practice on the part of physicians may contribute to the undertreatment of cancer pain in Taiwan. To address these concerns, a survey among physicians and fifth-year medical students relevant to cancer pain management (CPM) was carried out in a medical school and its principal teaching hospital. METHODS: A questionnaire on CPM was sent to 97 physicians and 78 fifth-year medical students (equivalent to the third-year medical students in the United States). The same questionnaire was delivered again to these 78 fifth-year medical students after they had completed a modified curriculum of anesthesiology with a 4-hour course on introduction to clinical pharmacology of CPM. RESULTS: The physicians knowledgeable on pain (physicians of anesthesiology, hematology-oncology, or radiation oncology), physicians unfamiliar with pain (outside of anesthesiology, hematology-oncology, or radiation oncology), and the 5th-yr medical students took similar negative attitudes (24-92%, 33-89%, and 23-94%) toward the optimal use of analgesics for CPM. As compared, the mean score on knowledge of prescribing opioids of pain-knowledgeable physicians was 3.60, the highest of all as against 2.61 of other physicians and 2.54 of 5th-yr medical students. On attitudes toward prescribing opioids, both pain-knowledgeable physicians and other physicians scored a higher means, respectively of 3.52 and 2.91 as opposed to 2.68 of 5th-yr medical students, the lowest of all. However, seniority or length of clinical practice did not improve knowledge or affect attitudes toward CPM. In addition, this 4-hour course did enable the 5th-yr medical students to take a more positive attitude toward and become more knowledgeable on CPM than pain-knowledgeable physicians, as a comparison was made. CONCLUSIONS: The effect of accumulation of clinical experience and seniority of clinical practice on CPM was limited among general physicians, except for clinical specialty on anesthesiology, hematology-oncology, or radiation oncology. In Taiwan, the knowledge of and positive attitude toward CPM could only be conveyed to physicians through undergraduate, post graduate or on-job education.

Knowledge and concerns about cancer in patients with primary gynecologic cancers.

OBJECTIVE: The aim of this study was to measure the level of knowledge about cancer among patients with primary gynecologic cancers and the rate of awareness for diagnosis. METHODS: Two hundred patients with primary gynecologic cancers in Vaie Asr & Mirza Kochak Khan hospitals, Tehran/Iran, participated and entered the study and were interviewed by trained nurses. The interview included questions about knowledge of their cancer and risk factors. RESULTS: One hundred fifteen of 200 subjects (58%) knew that their disease was malignant, of which 56 were aware of the exact diagnosis. Fifty six percent of the subjects believed that doctors must say the true diagnosis. The level of general knowledge about cancer was poor in 34%of cases. Regarding cancer risk factors, 47% had a poor level of knowledge. Misconception about injury and depression as predisposing factors were common. Level of general knowledge was significantly higher in younger than in older patients (p<0.05). Also patients with a greater length of formal education had a higher level of knowledge (p<0.0001). Patients who received information from medical personnel and who were aware of diagnosis had a higher level of knowledge (p<0.0001). CONCLUSION: The level of knowledge about cancer should be promoted in both the general public and in patients. Medical personnel may play a great role in this field.

A quality of care issue: appropriate use and efficacy knowledge of five contraceptive methods: views of men and women living in low socioeconomic settlements of Karachi, Pakistan.

OBJECTIVE: To assess knowledge regarding availability, affordability, appropriate use and efficacy for five non-permanent contraceptive methods. METHODS: Married Muslim women and men (500 each) were randomly selected from two low socioeconomic settlements in Karachi, Pakistan. Interviews to assess their knowledge on a range of contraceptive and abortion themes were conducted. Four hundred men and 357 women were selected from this larger sample based on their knowledge of condoms, withdrawal, oral pills, injectables and IUDs. RESULTS: Nearly half of the sampled men (56%) and women (48%) were contraceptive users. Knowledge regarding contraception, a specific method, its availability and affordability was high. Appropriate use knowledge for condoms was 73% among men (users 78%, non-users 60%; p-value < or = 0.001 ) and 5% among women. Efficacy knowledge was generally poor. CONCLUSIONS: Low knowledge levels regarding appropriate use and efficacy even among contraceptive users suggests, that quality of family planning services should not be limited to service delivery issues but extend to appropriate use and efficacy knowledge levels among clients.

[Between collegial conversation and controlled trials: hospital-based neurologists' sources of information and their practical knowledge in the treatment of stroke patients].

The application of evidence-based and standardized knowledge is an important basis for coordinated and effective clinical work. A multicenter study, which was conducted in 30 clinical neurology departments and included 99 junior and senior registrars, addressed aspects of practical knowledge of stroke treatment by open structured oral interviews which were analyzed with respect to interphysician and guideline conformity. In addition, the participants were asked to rate the usefulness of various informational sources and describe their informational sources used according to the aspects of practical knowledge addressed. The respective departmental directors were questioned about the sources of medical knowledge accessible in their clinic. In almost all hospitals, physicians had access to a library and the Internet. However, departments differed with respect to their information management (frequency and type of medical education, quality management, participation in research activities). In accordance with other studies, the knowledge sources reported most often were textbooks, journals and clinical studies. For most sources, the usefulness rankings largely corresponded to the rankings of user behavior. Both were only weak predictors for interphysician and guideline conformity. They are more closely related to the within-department homogeneity of practical knowledge than to interdepartmental and guideline conformity. Within-department homogeneity is enhanced by the use of recent, published and evidence-based sources and topical interaction with clinical colleagues. Guideline conformity was related to the use of databases and professional journals. A preference for colleagues from out-patient practices diminished both interphysician and guideline conformity. It seems there is still untapped potential for within-department knowledge management, such as medical education, implementation and use of guidelines and topical discussions, which may enhance the homogeneity and guideline conformity of the practical knowledge that clinicians apply.

Knowledge and attitude of youth (ages 15-25 years) to HIV/AIDS and to routine HIV screening.

BACKGROUND: AIDS is still an incurable disease and is very costly to control. Since the first case of Acquired Immune Deficiency Syndrome (AIDS) in Nigeria was reported in 1986, the human immune deficiency virus (HIV) infection has attained epidemic proportion. In an effort to control this rapid spread, certain preventive measures have been developed. In spite of these and the campaigns to control it, the knowledge and attitudes of youths towards HIV/AIDS leaves much to be desired. OBJECTIVE: To determine knowledge and attitude of youths (15 - 25 years) of HIV/AIDS and to Routine HIV Screening. STUDY DESIGN: The study was cross-sectional. SETTING: The study was carried out at the University of Benin Teaching Hospital, Benin City, Nigeria, between January and December 2003. RESULTS: Five thousand three hundred and twenty STUDY POPULATION: The knowledge and attitude of youths (15 - 25 years) of HIV/AIDS and to routine HIV screening was assessed, using anonymous questionnaires, among 9500 respondents, 4950 males and 4550 females. 5750 respondents were from the University of Benin with a population of 20,000 students while 3750 were from some of the Secondary Schools (post primary Schools) randomly selected in Benin City, Nigeria. The University of Benin Teaching Hospital where the work was done is adjacent to the University of Benin. The Secondary Schools selected where the work was done were within a radius of 20 kilometers of the Teaching Hospital and were 5 in numbers with average of 750 students selected per school. Subjects (56%) indicated that they have heard about HIV/AIDS, 4180 (44%) had no knowledge of HIV/AIDS at all. 2240 of 5320 (42.1%) had some knowledge; 1593 (29.9%) had adequate knowledge and only 1487 (28.0%) had sufficient knowledge. 6365 (67%) did not believe it exists and as a result they are not bothered by it. 825 of the 3750 secondary school students had multiple sexual partners. Majority had single partners for those who had at all. While among the University students 2990 (52%) had multiple sexual partners, while others had between one and two sexual partners. Only 36210 (38%) believe it is real and a killer disease frightened about it and are already changing their sexual behaviours; 1900 (20%) believe it is a western propaganda to enslave the developing world. Three thousand nine hundred and ninety respondents (42%) would agree to routine HIV screening and 5510 (58%) would not agree to routine screening. The reasons adduced for rejecting routine HIV screening included psychological trauma, not necessarily high cost of and lack of anti-retroviral drugs, infringement on fundamental human rights, fear of living with positive screening, stigmatization and victimization at place of work if positive. CONCLUSION: Intensive massive awareness campaign through Radio, Televisions jingles and education about HIV/AIDS of the population is recommended to alter their current negative attitude to routine HIV testing and increase their knowledge about HIV/AIDS and perhaps help to change their sexual behaviours.

Modeling end-users' acceptance of a knowledge authoring tool.

OBJECTIVES: Knowledge bases comprise a vital component in the classic medical expert system model, yet the knowledge acquisition process by which they are created has been characterized as highly iterative and labor-intensive. The difficulty of this process underscores the importance of knowledge authoring tools that satisfy the demands of end-users. The authors hypothesize that the acceptability of a knowledge authoring tool for the creation of medical knowledge base content can be predicted by an accepted model in the information technology (IT) field, specifically the Technology Acceptance Model (TAM). METHODS: An online survey was conducted amongst knowledge base authors who had previously established experience with the authoring tool software. The Likert-based questions in the survey were patterned directly after accepted TAM constructs with minor modifications to particularize them to the software being used. The results were analyzed using structural equation modeling. RESULTS: The TAM performed well in predicting endusers' behavioral intentions to use the knowledge authoring tool. Five out of seven goodness-of-fit statistics indicate that the model represents the behavioral intentions of the authors well. All but one of the hypothesized relationships specified by the TAM were significant with p values less than 0.05. CONCLUSIONS: The TAM provides an adequate means by which development teams can anticipate and better understand what aspects of a knowledge authoring tool are most important to their target audience. Further research involving other behavioral models and an expanded user base will be necessary to better understand the scope of issues that factor into acceptability.

Spouse similarities in high blood pressure knowledge: implications for control of high blood pressure.

This study describes the general knowledge about high blood pressure of husbands and wives using data from all 1,260 white spouse pairs from the 1982 Connecticut Blood Pressure Survey and examines the relationship between high blood pressure knowledge and control of hypertension. We found the average level of knowledge to be high; about 70% of the items were answered correctly. The correlation between spouses' knowledge about high blood pressure was significantly high (r = .41). Multiple regression analysis was used to control for other variables that might influence the spousal correlation in knowledge. When controlling for education, age, socioeconomic status, and hypertension status of both spouses, the correlation between spouses' knowledge remained significant (r = .24). Respondents' knowledge and spouses' knowledge about high blood pressure were significantly related to high blood pressure control among hypertensive persons, particularly to being aware of hypertension and being in current treatment.

[Attitude and knowledge on AIDS at a maternity unit in Santiago de Chile].

An inquest to determine the degree of knowledge they have, was done among 27 physicians (obstetricians-gynecologist), 36 midwives and 47 assistants of infirmary in a maternity of Santiago. The following items where included: definition of concept, general knowledge, ways of transmission, prevention and treatment, communication and educational means, recommendations, comments, suggestions and specific knowledge. We proved that even though the general knowledge is apparently good for physicians, midwives and assistants of infirmary, they don't have adequate knowledge of the mechanisms of transmission of AIDS, of its prevention and no specific knowledge. They do have wrong ideas upon the topic. This lack is evident in assistants of infirmary and in a less degree in midwives and physicians. Considering that the group to be studied works in the specific health area dealing with gynecology and obstetrics, it is expected that they have a high grade of knowledge in relation with AIDS, due to the fact that they are a group of high risk in getting the disease and that they are a multiplicator factor of education among the population. This makes necessary to give periodic training courses and to reinforce the knowledge of such personnel.
