Increasing paramedics' comfort and knowledge about children with special health care needs.

This study evaluated a continuing education program for paramedics about children with special health care needs (CSHCN). Pretraining, posttraining, and follow-up surveys containing two scales (comfort with CSHCN management skills and comfort with Pediatric Advanced Life Support [PALS] skills) were administered. Objective measures of knowledge were obtained from pre- and posttraining tests. Differences in average scores were assessed using t-tests. Response rates for paramedics completing the program ranged from 94% for the posttraining survey, 81% for the initial comfort survey, 56% for the knowledge pretest, and 56% for the follow-up survey. PALS comfort scores were significantly higher than CSHCN comfort scores both before and after training, both P < .01. Posttraining surveys showed an increase in CSHCN comfort, P < .01. The follow-up surveys showed a significant decline in CSHCN comfort, P = .05. Scores on the tests showed a similar pattern, with a significant increase in knowledge from pre- to posttraining (P = .02) and a significant decrease in knowledge from posttraining to follow-up (P < .01). Comfort was significantly higher for standard pediatric skills than for specialized management skills. Completion of the self-study program was associated with an increase in comfort and knowledge, but there was some decay over time.

The effect of diet education on the laboratory values and knowledge of hemodialysis patients with hyperphosphatemia.

OBJECTIVE: The purpose of this study was to evaluate the effectiveness of 20 to 30 minutes per month of additional diet education on monthly laboratory values (phosphorus, calcium, parathyroid hormone, and calcium/phosphorus product) and knowledge of dietary phosphorus management in hemodialysis patients with hyperphosphatemia. DESIGN: A quasi-experimental design. SETTING: Three outpatient dialysis centers owned by the same corporation in 1 southern state. PATIENTS: Based on a 3-month average serum phosphorus >6.0 mg/dL, 70 patients were selected for participation; 63 dialysis patients completed the study, 32 in the experimental group and 31 in the control group. INTERVENTION: All patients completed a before-and-after knowledge test and had monthly blood samples drawn. Each month, the same registered dietitian provided the routine laboratory results review with control group. The experimental group received the routine laboratory review plus 20 to 30 minutes of additional diet education specifically targeting phosphorus. Main outcome measures Before-and-after knowledge test results and baseline and final serum calcium, phosphorus, parathyroid hormone, and calcium/phosphorus product levels. RESULTS: At baseline, there were no significant differences in any of the laboratory values, but the knowledge level of the experimental group was greater (P <.05) After 6 months, gains in knowledge were significantly higher in the intervention group, and the serum phosphorus and calcium/phosphorus product levels were significantly lower (P <.01) than in the control group. CONCLUSION: Based on this research, those patients who received extra education monthly showed positive changes, which may be beneficial in reducing hyperphosphatemia.

Dental hygienists and infection control: knowledge, attitudes and behaviour in Italy.

This study evaluated knowledge, attitudes and behaviour regarding infection control of dental hygienists in Italy. Among the 185 responders to the self-administered mailed questionnaire, 91.3% agreed with the correct responses to the three questions on knowledge about infection prevention and control procedures chosen as an indicator of 'good' knowledge. However, 21% were uncertain whether, or disagreed that, dental instruments should be rinsed in water after contact with glutaraldehyde and 17.5% agreed that, or were uncertain whether, 10 min contact with glutaraldehyde provided sterilization. Only 36.5% knew all the five oral manifestations of acquired immunodeficiency syndrome (AIDS) (acute periodontal problems, candidiasis, hairy leukoplakia, herpes simplex virus, Kaposi's sarcoma) and this knowledge was significantly higher in dental hygienists with a lower number of years of practice. More than two-thirds used a steam sterilizer or glutaraldehyde for appropriate times and temperatures for disinfection/sterilization of instruments and used appropriate surface disinfection procedures. The correct application of disinfection or sterilization methods for instruments was more likely in the older respondents and in those who attended continuing education courses on infection control. A positive attitude was reported by the majority of dental hygienists who agreed that guidelines should be maintained and applied and was significantly more likely in younger respondents. Only 57.9% routinely follow all recommendations for infection control practices and their use was significantly higher in the older respondents. Educational programmes are needed for improving knowledge about oral manifestations of AIDS in order to support dentists to provide early diagnosis and about the correct use of procedures and universal precautions for preventing infections.

Nursing students' knowledge of and views about children in pain.

It is important to evaluate the outcomes of the given education to gain knowledge about the abilities of our students to meet the needs of nursing practice. Pain associated with different illnesses and procedures is one of the most common symptoms that children experience in the hospital. The purpose of this study was to evaluate the views and knowledge base of graduating nursing students in the area of taking care of children in pain. The data were collected with a purpose-designed Likert-type instrument from all nursing students that graduated during one year from the child nurse specializing program in Finland (n = 85), with a response rate of 86%. Results indicate that students have mainly positive views and attitudes towards taking care of children in pain. The views and attitudes differ when older and younger students and students from different schools are compared. Students lack knowledge especially in the area of pain medications as well as in the assessment of pain. In the knowledge section, the results did not differ greatly when different schools, younger and older students or previous working experience and no working experience were compared. In some of the researched schools, many of the students felt a lack of confidence about their knowledge. There is a need for more detailed education in the area of taking care of children with pain.

Distinct neural systems subserve person and object knowledge.

Studies using functional neuroimaging and patient populations have demonstrated that distinct brain regions subserve semantic knowledge for different classes of inanimate objects (e.g., tools, musical instruments, and houses). What this work has yet to consider, however, is how conceptual knowledge about people may be organized in the brain. In particular, is there a distinct functional neuroanatomy associated with person knowledge? By using event-related functional magnetic resonance imaging (fMRI), we measured neural activity while participants made semantic judgments about people or objects. A unique pattern of brain activity was associated with person judgments and included brain regions previously implicated in other aspects of social-cognitive functioning: medial prefrontal cortex, superior temporal cortex, intraparietal sulcus, and fusiform gyrus. These regions were generally marked by relatively little change from baseline brain activity for person judgments along with significant deactivations for object judgments. Together, these findings support the notion that person knowledge may be functionally dissociable from other classes of semantic knowledge within the brain.

"What" and "how": evidence for the dissociation of object knowledge and mechanical problem-solving skills in the human brain.

Patients with profound semantic deterioration resulting from temporal lobe atrophy have been reported to use many real objects appropriately. Does this preserved ability reflect (i) a separate component of the conceptual knowledge system ("action semantics") or (ii) the operation of a system that is independent of conceptual knowledge of specific objects, and rather is responsible for general mechanical problem-solving skills, triggered by object affordances? We contrast the performance of three patients-two with semantic dementia and focal temporal lobe atrophy and the third with corticobasal degeneration and biparietal atrophy-on tests of real object identification and usage, picture-based tests of functional semantic knowledge, and a task requiring selection and use of novel tools. The patient with corticobasal degeneration showed poor novel tool selection and impaired use of real objects, despite near normal semantic knowledge of the same objects' functions. The patients with semantic dementia had the expected deficit in object identification and functional semantics, but achieved flawless and effortless performance on the novel tool task. Their attempts to use this same mechanical problem-solving ability to deduce (sometimes successfully but often incorrectly) the use of the real objects provide no support for the hypothesis of a separate action-semantic system. Although the temporal lobe system clearly is necessary to identify "what" an object is, we suggest that sensory inputs to a parietal "how" system can trigger the use of objects without reference to object-specific conceptual knowledge.

Oral health-related knowledge, attitudes, and beliefs among 11 to 12-year-old Finnish schoolchildren with different oral health behaviors.

The aim of this study was to explore oral health-related knowledge, attitudes, and beliefs among 11 to 12-year-old schoolchildren with favorable, moderate, or poor behavior related to oral health. The data were gathered by questionnaire. Recommendations commonly used in Finland in oral health education were chosen as the criteria for selection of groups of children with favorable, moderate, and poor oral health behavior. Differences between groups were analyzed using crosstabulations and factors related to unfavorable behavior using logistic regression analysis. The percentage of children with appropriate knowledge was higher in the good behavior group (GB) than in the other groups. The groups differed most in the children's knowledge of the recommendation to use fluoride toothpaste at least twice a day. Most children in the GB group considered it important to brush their teeth for the fresh feeling this gave. The majority of children in all groups considered it important to brush their teeth when going to the dentist. The majority also considered brushing important for avoiding tooth decay and tooth discoloration as well as for having fresh breath. Unfavorable knowledge, attitudes, beliefs, and behavior tended to accumulate in the same children. Factors associated with unfavorable behavior were male sex, mother's low skill occupation level, and child's poor knowledge of oral health-related facts.

A logistic regression model for analyzing the relation between dentists' attitudes, behavior, and knowledge in oral radiology.

The aim was to study the relation between risk attitude and knowledge in technical, patient-oriented, and organizationally related behavior within oral radiology. A questionnaire was mailed to 2000 randomly selected dentists listed in the register of the Swedish Dental Society, with a response rate of 69.3%. Regression analysis was used for analyzing the effects of the independent variables knowledge, risk attitude, continuing education in oral radiology, counties with specialists in oral radiology, type of practice, work experience, and sex on three categories of dependent variables: 1) technical behaviors: type of film, type of collimator, dose level, frequency of change of chemicals; 2) patient-oriented behaviors: use of patient protection barriers, strict indications for performing full-mouth X-ray examinations and bitewing radiography on new patients and recall patients; and 3) organizationally related behaviors: delegation of X-ray examinations to dental auxiliaries, influence on choice of collimator, influence on choice of film. Knowledge and education had strong direct effects for most of the dependent variables. The technical behaviors were mainly influenced by knowledge, education, and risk attitude, while organizationally related behaviors were influenced by type of practice and sex. The patient-oriented behaviors were influenced by a number of independent variables, such as education, type of practice, work experience, and sex. The present results indicate that both knowledge and the organizational context of dentists influence work.

An analysis, using concept mapping, of diabetic patients' knowledge, before and after patient education.

This study was designed to assess whether concept maps used with diabetic patients could describe their cognitive structure, before and after having followed an educational programme. Ten diabetic patients, in Paris and Geneva, were interviewed and, during the interview, a concept map was drawn up by the researcher, using the patient's words. This was done on three different occasions: the first day of the educational programme (Pre-evaluation), the last day (Post 1) of a week of education, then 3 to 4 months after education (Post 2). Twenty-eight maps were analysed, using a grid that quantified and qualified the knowledge expressed (knowledge categories, concept links, exactitude) and the organization of that knowledge (hierarchization of concept, cross-links). The examples shown in the maps of the 10 patients gave an illustration of how knowledge was developed or maintained with education, and also showed some learning difficulties encountered by the patients, the changes or preservation of their beliefs and the patients' preoccupations. This study shows that concept maps can be a suitable technique to explore the type and organization of the patients' prior knowledge and to visualize what they have learned after an educational programme.

Breast cancer knowledge, attitudes and practice among nurses in Lagos, Nigeria.

A cross-sectional survey was conducted among nurses working in a general hospital in Lagos to determine their knowledge, attitude and practice regarding breast cancer. A self-administered questionnaire was used to investigate knowledge of symptoms, methods of diagnosis and use of cancer screening methods. Two hundred and four nurses out of 280 participated in the study (73% response rate). Knowledge about symptoms, methods of diagnosis and self-breast examination was generally very good. However, only 30% had had a clinical breast examination and 8% a mammogram within the past three years. Use of cancer screening methods was significantly associated with knowledge of the subject (p = 0.03). Twenty-eight percent did not know how to estimate the risk of cancer and 61% believed they were not at risk. Nurses possess adequate knowledge about breast cancer but they need more information on cancer risk estimation.

Living arrangements, knowledge of health risks, and stress as determinants of health-risk behavior among college students.

The association of knowledge of health risks, living arrangements, and perceived stress with health-risk behaviors was examined in a sample of college students included in the Health Promotion and Disease Prevention Supplement of the National Health Interview Survey. Regressions of each health-risk behavior (dependent variable) were performed on the predicted correlates. Although knowledge was not associated with participation in physical activity or smoking, the study found that students who knew more about the harmful effects of alcohol drank less, and those with greater knowledge of health risks practiced fewer risky behaviors. Students living independently were more likely to smoke, and those living in residence halls were less like to do so. Drinking, however, was more common among students living in residence halls or independently than among those living at home. Hall residents engaged in more group physical activity than other students did, but their physical activity was unrelated to health-risk behaviors. Stress was associated with smoking but not with other health practices. The findings suggest that smoking may be less influenced by health knowledge and more associated than drinking is with a response to stress. Drinking appears to be a social activity associated with living among peers and is potentially modifiable by increased knowledge about the effects of alcohol on health.

Turkish people's knowledge of cancer and attitudes toward prevention and treatment.

BACKGROUND: The basic level of cancer knowledge of the population is as important in controlling cancer as diagnostic tools, screening, and new approaches to prevention, early diagnosis, and treatment. METHODS: A questionnaire consisting of 24 questions was given to 630 healthy Turkish people to determine their basic knowledge and attitudes regarding cancer. RESULTS: The majority of respondents (78%) were found to have little knowledge of cancer despite the fact that the average level of education of the sample was superior to that of the general population. Educational level was the major predictive factor influencing the basic knowledge and attitudes of the respondents. CONCLUSION: The overall education of the public as well as the basic level of knowledge of cancer must be improved in cooperation with oncology societies and media in order to overcome the cancer burden in Turkey.

Women's knowledge and beliefs about breast cancer risk factors, symptoms, detection methods, and treatments.

This paper presents results from a survey of adult women that assessed knowledge, beliefs, and practices regarding the causes, symptoms, detection methods, and treatment of breast cancer. The study population was determined through random selection of household telephone numbers from the Buffalo, New York area telephone directory. Completed interviews were collected from 563 women over the age of 18. Telephone interviews were conducted by trained interviewers, between April and July of 1985. Survey results are compared to those found in the 1979 National Cancer Institute nationwide survey on breast cancer to evaluate if ther have been changes in public awareness about the disease. Differences in knowledge, beliefs, and practices regarding breast cancer were also studied in relation to age, race, and educational background. Overall, women's knowledge about breast cancer has significantly increased since the 1979 survey. However, while more women can name mammography as a diagnostic tool only 15% of women who have heard of mammography reported having had a mammogram. Generally, younger women, white women and those with some college education were more knowledgeable about breast cancer risk factors, symptoms, detection methods, and treatments. Results from this study suggest that although knowledge about breast cancer has improved, women have not adopted recommended early detection practices. Special efforts need to be directed toward health professionals, making mammography more accessible to women who are nonwhite, older and with no college education.

Evaluation of the effects of cancer education on knowledge, attitude, and behavior of university undergraduate students.

Reviews indicate that multiple predisposing factors such as knowledge, attitudes, and values significantly influence health-related practices and lifestyle. Some predispositions, such as basic knowledge about and attitudes toward cancer, are conducive to change through education. This study has investigated the effects of cancer education on the knowledge, attitude, and behavior scores of students concerning cancer prevention. A quasiexperimental design using pretests and posttests was the design of choice. The undergraduate students served as the experimental group and enrolled in an elective course entitled "The Nature of Cancer." Another group of students enrolled in the elective course "Sex Education" and served as a control group for one semester. A battery of instruments consisting of cancer prevention attitudes, knowledge, and behavior was used to measure the dependent variables. The findings, using a split-plot model for repeated measure data, revealed significant improvements in attitude, knowledge, and behavior scores for the experimental group over the control group.

Cancer knowledge and misconceptions among college undergraduates: a pilot study.

A study of cancer knowledge and misconceptions among college undergraduates was undertaken with the goal of obtaining information that could be used to direct the establishment of future, problem-oriented cancer education programs. General knowledge about cancer, as well as specific knowledge about colon cancer, was found to be lacking. The former was significantly related to gender, while the latter was influenced by a family history of cancer. Knowledge about breast cancer was more complete, although, again, gender significantly impacted upon accuracy. Breast self-examination and surgical options for treating breast cancer were specific areas in which knowledge was poor.

Smoking, dietary, and breast and cervical cancer screening knowledge and screening practices of employees in an urban medical center.

This paper reports results of a survey of 500 health care workers in a private New York City Hospital that assessed knowledge and behaviors in the areas of smoking and cancer, diet and cancer, and breast and cervical cancer screening. Given the small number of knowledge items, the results indicated good knowledge concerning diet and cancer, smoking and cancer, and mammography and Pap test guidelines. Conformity with American Cancer Society guidelines for Pap testing was comparable to national figures, but with women over 50 as likely to obtain Pap smears as younger women. Conformity with mammography guidelines was excellent, although compliance with breast self-examination recommendations was low (25.4%). Of female employees over age 50, 87.4% had ever had mammography and 77.6% reported yearly mammography. Only 19% of the respondents admitted to current smoking. Although methodologic differences made comparison of knowledge of diet and cancer with the work of others difficult, knowledge of the risks of smoking was comparable to levels found in other studies.

HIV-infected adolescent and adult perceptions of tuberculosis testing, knowledge and medication adherence in the USA.

HIV-infected adolescent and adult perceptions of tuberculosis (TB) infection rates and physician TB behaviour, and patient knowledge of TB transmission and treatment adherence were assessed. HIV-infected youth (N = 199) from adolescent clinical care sites in three cities and HIV-infected adults (N = 133) in New York were interviewed. Adolescent self-report was compared to medical chart review. Adolescents reported they were significantly less likely to be tested, although testing rates were high for both samples. Approximately 9% of both samples reported infection with TB; the majority of whom reported receiving medication (97%), and consistent medication adherence (93%). The overall mean knowledge score was 66%, with significant age differences: adolescents were less knowledgeable than adults, and young males tended to be less knowledgeable than young females. Age, gender and experience with TB (self-perception of TB, testing history and clinic choice) significantly predicted accuracy of knowledge about TB. Results suggest that if HIV-infected individuals--a population at very high risk and often among the least able to afford health care resources--receive the education and support they need from their community health care sources they may substantially reduce their chances of contracting and spreading TB.

Knowledge, risk perceptions and condom usage in male sex workers from three Australian cities.

The study identifies factors associated with knowledge and perception of risk of HIV/AIDS, as well as attitudes to and usage of condoms by a sample of male sex workers (MSW). One hundred and eighty-five male sex workers completed a self-reported questionnaire, including knowledge about HIV transmission, attitudes to condom use and perceptions and personal susceptibility to HIV and sexually transmitted infection (STI) risk, and a two-week diary recording use of condom during commercial sex encounters. The findings reveal that condom use was found in 77.7% of the encounters with clients and the majority of the respondents perceived themselves to be at no risk for HIV because of sex work. Independent sex workers from Melbourne and workers who owned their place of residence used condoms in a significant lower proportion. Generally speaking, knowledge about the risks associated with AIDS was high, with respondents showing lower knowledge about the risks associated with unprotected receptive or active oral sex. Participants held a positive attitude to condom use; most considered the provisions of condoms to be their responsibility rather than clients; and they were more worried about contracting an STI than HIV. Those who scored higher on the knowledge scale had more positive attitudes to condom use and those who had a more positive attitude to condom use recorded a perceived lower risk of contracting STI but not HIV. The study discusses the relevance of these findings for public health risk reduction and sexual health education campaigns.
