Methicillin-resistant Staphylococcus aureus: awareness and perceptions.

The purpose of this study was to investigate levels of awareness and the perceived risk of contracting methicillin-resistant Staphylococcus aureus (MRSA) amongst patients/visitors and employees of the UK National Health Service (NHS). Differences between the two cohorts were also investigated, particularly sources of information about MRSA. In March 2005, a piloted questionnaire was circulated to 50 patients/visitors and 100 NHS employees (25 doctors, 25 nurses, 25 domestics and 25 porters). No information was returned from porters, but the overall response rate was 67%. There was a high level of awareness of MRSA among both patients/visitors (94%) and NHS employees (100%). General media was the most common source of information for patients/visitors (68%) compared with 24% of NHS employees (P < 0.01). Perceived risk of contracting MRSA was very similar among patients/visitors and NHS employees (34% vs 35%, P > 0.10). Fifty-two percent of doctors felt that they were at risk compared with 13% of domestic employees. In conclusion, this study showed a high level of awareness among the general public and healthcare workers alike.

Posture, movement patterns, and body awareness in women with chronic pelvic pain.

OBJECTIVE: Chronic pelvic pain (CPP) is a common cause of infirmity but is still poorly understood. We studied the clinical characteristics, including body awareness, of 60 women with this diagnosis compared to those of healthy controls in an effort to understand its pathophysiology and to develop a more efficient treatment protocol. METHODS: After prior gynecologic and psychometric evaluation, the women were examined with the Standardized Mensendieck Test to evaluate posture and movement patterns. Pain history and pain score were obtained, and patterns of muscular density, elasticity, and tenderness were determined by palpation. The body awareness of patients was assessed through clinical evaluation. RESULTS: Seventy percent of the patients had a history of trauma or infection of the genitourinary region. The average pain score (+/-S.D.) on a scale from 0 to 10 was 6.01+/-1.60. Nearly all patients had a dissociative pattern, with a lack of contact and control of large body regions. All scores for posture and movement patterns were significantly worse in patients than in healthy women. CONCLUSION: A specific pattern of pain, posture, movement, muscle pathology, and reduced awareness of one's own body was found in women with CPP. These findings may increase our understanding of, and may point toward new treatment strategies for, this disease.

Improving older driver knowledge and self-awareness through self-assessment: the driving decisions workbook.

PURPOSE: This study aims to assess whether the Driving Decisions Workbook, a self-assessment instrument for older drivers, increased self-awareness and general knowledge. This study also assessed perceptions regarding its usefulness, particularly as a tool for facilitating discussions within families of older drivers. A secondary purpose of the study was to determine if problems identified by drivers in the workbook related to problems they had with actual driving. DESIGN AND METHODS: The Driving Decisions Workbook was administered along with a questionnaire and a road test. A convenience sample of 99 licensed drivers aged 65 and above was used. RESULTS: After completing the workbook, about three fourths of the participants reported being more aware of changes that could affect driving. Fourteen percent reported that they had discovered a change in themselves of which they had not been previously aware. All respondents found the workbook to be at least a little useful and thought the workbook could help facilitate family discussions. Workbook responses were positively correlated with overall road test scores. Significant correlations were also noted between the road test and a majority of workbook subsection responses. IMPLICATIONS: This study indicates that the workbook may be a useful first-tier assessment instrument and educational tool for the older driver. It may encourage an older driver to drive more safely and/or to seek clinical assessment, and help in facilitating discussions about driving within their families.

Are patients aware of the association between smoking and bladder cancer?

PURPOSE: Smoking is the single greatest risk factor for bladder cancer. Since few studies have demonstrated the efficacy of screening for bladder cancer, primary prevention by decreasing the modifiable risk factors is the best defense. An aspect of modifying a behavioral risk factor is awareness of the association between behavior and disease. While many anti-smoking campaigns specifically focus on lung cancer, few mention bladder cancer. We evaluated the awareness of smoking as a risk factor for bladder cancer. MATERIALS AND METHODS: Between February and May 2005 we prospectively surveyed patients presenting to a urology clinic regarding their knowledge of risk factors for bladder cancer and other cancers. The questionnaire also captured data regarding patient smoking habits. RESULTS: A total of 280 patients completed the survey, including 34% who were younger than 50 years, 63% who were male, 89% who were white and 57% who were college graduates. Only 36% vs 98% of the sample reported that smoking was a risk factor for bladder vs lung cancer. Patients with a higher level of education and females were statistically more likely to be aware of the association between smoking and bladder cancer. CONCLUSIONS: Patients at a urology clinic had low overall knowledge regarding bladder cancer risk factors. Most patients queried had no idea regarding the relationship between bladder cancer and tobacco use regardless of smoking status. Our study suggests the need for the American public to be better educated to help combat smoking related cancers.

Self-awareness of cognitive functioning in schizophrenia.

Poor awareness of psychiatric symptoms is associated with schizophrenia. It is unclear whether this lack of insight extends to the cognitive impairment that affects at least 85% of people with schizophrenia. Given the increasing efforts to develop treatments for cognitive impairment, and the link between awareness of disability and treatment compliance, it is important to understand whether people with schizophrenia have awareness of their cognitive deficits. Ratings of cognitive functioning from 185 outpatients diagnosed with schizophrenia, their clinicians' ratings and objective neuropsychological test results were compared in the following cognitive domains: attention, nonverbal memory, and verbal memory. The results indicated that there was poor concordance among the three assessments. Patients did not agree with their clinician's assessments and did a very poor job of accurately classifying their cognitive status. However, clinicians were also poor at classifying cognitive status consistent with neuropsychological test results. The implications of these findings for understanding insight in schizophrenia are discussed.

Awareness and knowledge of epilepsy among students in a Malaysian university.

PURPOSE: University students represent a better-educated group of society and it is important that they possess the correct knowledge and attitude towards healthcare issues. The aim of this study was to determine the current level of awareness and knowledge of epilepsy among students at a public university in Malaysia. METHODS: A survey was conducted within the main campus of the Universiti Sains Malaysia (USM), Penang, Malaysia. Students were required to answer a series of questions on awareness and knowledge of epilepsy. The questionnaire was written in the Malay language. RESULTS: Over a one-week period, 289 students completed the self-administered questionnaire. It was found that 86.5% of students had heard or read about epilepsy, while 55.6% had observed an epileptic seizure. Only 30.7% said that they knew the cause of epilepsy and 5.3% thought epilepsy was caused by evil spirits. Epilepsy was considered hereditary by 66.9% of respondents, while 4.9% thought it was contagious. Furthermore, 60% of students did not think that epilepsy was a shameful illness. CONCLUSIONS: The findings indicate a generally favorable level of awareness and knowledge of epilepsy among students at the university. Nevertheless, there is still a need to improve certain aspects of knowledge and understanding of epilepsy among university students.

The neural correlate of (un)awareness: lessons from the vegetative state.

Consciousness has two main components: wakefulness and awareness. The vegetative state is characterized by wakefulness without awareness. Recent functional neuroimaging results have shown that some parts of the cortex are still functioning in 'vegetative' patients. External stimulation, such as a painful stimulus, still activates 'primary' sensory cortices in these patients but these areas are functionally disconnected from 'higher order' associative areas needed for awareness. Such studies are disentangling the neural correlates of the vegetative state from the minimally conscious state, and have major clinical consequences in addition to empirical importance for the understanding of consciousness.

What's in store for medical students? Awareness and utilization of expert nutrition guidelines among medical school preceptors.

BACKGROUND: Instruction of physicians and other health professionals in medical nutrition sciences is among the expert recommendations to promote population health and reduce risks for cancer and other major causes of morbidity and mortality in the population. However, formal training in nutrition in United States medical schools is still lacking compared to the gains in basic and applied medical nutrition sciences. We sought to understand the awareness and current utilization of expert nutrition recommendations and practice guidelines among medical student faculty preceptors. METHODS: We surveyed the teaching faculty who precept for first-, second-, and third-year medical students in two required courses at Boston University. The instrument queried preceptor awareness and current utilization of expert nutrition recommendations, nutritional management practice guidelines, as well as faculty-student interactions regarding patient nutritional education and counseling. RESULTS: Of 187 faculty surveyed, 139 (74%) responded. Faculty reported using 2.3 expert guideline sources (N = 111; SD = 1.8; range = 0-8) but 83% had considered only one or no sources or did not remember what guidelines they had used. Eighty-four percent of preceptors expected students to routinely discuss nutritional practices with patients and/or their families; however, less than half of preceptors routinely provided feedback to students on patient nutritional education or counseling strategies. CONCLUSION: Our findings suggest gaps in faculty awareness and utilization of expert nutrition recommendations and practice guidelines relating to cancer and other chronic disease-risk reduction and population health promotion, underscoring the need for improvements in faculty and medical student training in basic and applied medical nutrition sciences.

Appropriate antibiotic use: variation in knowledge and awareness by Hispanic ethnicity and language.

BACKGROUND: Recent campaigns are informing the public that antibiotics are inappropriate for viral respiratory infections. As little is known about their effect on populations challenged by less access to care, lower education, low income, low English proficiency, or non-mainstream cultural backgrounds, this study assessed knowledge, attitudes, and awareness in an ethnically diverse community. METHODS: A telephone survey in English or Spanish of a cross-sectional, random sample of 692 non-Hispanic whites (NHWs) and 300 Hispanics in Colorado. RESULTS: For all respondent groups, knowledge of appropriate antibiotic use for colds and bronchitis was low. Hispanics surveyed in Spanish, compared with non-Hispanic whites, had significantly lower knowledge about antibiotics for colds, higher knowledge for bronchitis, lower awareness about antibiotic resistance, and greater dissatisfaction if an antibiotic were not prescribed. In all comparisons, English-language Hispanics tended to reflect non-Hispanic white response patterns. Independent predictors of awareness were ethnicity, education, and age. Independent predictors of dissatisfaction were ethnicity, knowledge about antibiotic use for colds, and bronchitis. Ethnicity was an independent predictor of knowledge about the inappropriateness of antibiotics for colds and bronchitis. CONCLUSIONS: To bridge knowledge gaps, educational campaigns for all segments of the population are needed. Content should be responsive to heterogeneity within populations.

Primary care physicians' awareness and adherence to cervical cancer screening guidelines in Texas.

BACKGROUND: Cervical cancer screening guidelines were created to help healthcare professionals in appropriate screening utilizing the PAP test. However, significant variation in cervical cancer screening among primary care physicians has been noted. Knowledge of the awareness of and adherence to cervical cancer screening guidelines by primary care physicians will help determine how best to disseminate and educate these physicians regarding the guidelines in hopes of reducing unnecessary screening and improving screening for under screened populations. METHODS: A cross-sectional, mailed survey involving Family Medicine (FP), Community Internal Medicine (CIM), and Obstetrics/Gynecology (OB) physicians practicing in a large University-affiliated, multi-specialty group practice associated with an 186,000-member HMO in Central Texas (n = 177) was conducted in 2001-2002. RESULTS: Most physicians performed PAP testing (50.4%). PAP screening was noted to vary significantly by specialty (P < 0.0001). All OBs were aware of at least one published guideline, compared to 96% of FPs and 91% of CIMs (P < 0.05). A wide variation was reported regarding adherence to published guidelines. In addition, there was significant intraspecialty variation regarding adherence to the physicians' own specialty's guidelines. CONCLUSIONS: While most physicians in the primary care setting perform PAP tests and are aware of published guidelines for PAP screening, adherence to the published guidelines varies considerably even in the same clinical setting.

Are physicians aware of which of their patients have indwelling urinary catheters?

PURPOSE: Although infections associated with indwelling urinary catheters are common, costly, and morbid, the use of these catheters is unnecessary in more than one-third of patients. We sought to assess whether attending physicians, medical residents, and medical students are aware if their hospitalized patients have an indwelling urinary catheter, and whether physician awareness is associated with appropriate use of these catheters. METHODS: The physicians and medical students responsible for patients admitted to the medical services at four university-affiliated hospitals were given a list of the patients on their service. For each patient, the provider was asked: "As of yesterday afternoon, did this patient have an indwelling urethral catheter?" Respondents' answers were compared with the results of examining the patient. RESULTS: Among 288 physicians and students on 56 medical teams, 256 (89%) completed the survey. Of 469 patients, 117 (25%) had an indwelling catheter. There were a total of 319 provider-patient observations among these 117 patients. Overall, providers were unaware of catheterization for 88 (28%) of the 319 provider-patient observations. Unawareness rates by level of training were 21% for students, 22% for interns, 27% for residents, and 38% for attending physicians (P = 0.06). Catheter use was inappropriate in 36 (31%) of the 117 patients with a catheter. Providers were unaware of catheter use for 44 (41%) of the 108 provider-patient observations of patients who were inappropriately catheterized. Catheterization was more likely to be appropriate if respondents were aware of the catheter (odds ratio = 3.7; 95% confidence interval, 2.1 to 6.7, P <0.001). CONCLUSION: Physicians are commonly unaware that their patients have an indwelling urinary catheter. Inappropriate catheters are more often "forgotten" than appropriate ones. System-wide interventions aimed at discontinuing unnecessary catheterization seem warranted.

Is there a causal link from phonological awareness to success in learning to read?

In this review, we re-assess the evidence that phonological awareness represents a skill specific to spoken language that precedes and directly influences the process of reading acquisition. Longitudinal and experimental training studies are examined in detail, as these are considered most appropriate for exploring a causal hypothesis of this nature. A particular focus of our analysis is the degree to which studies to date have controlled for existing literacy skills in their participants and the influence that these skills might have on performance on phonological awareness tasks. We conclude that no study has provided unequivocal evidence that there is a causal link from competence in phonological awareness to success in reading and spelling acquisition. However, we believe that such a study is possible and outline some ideas for its design and implementation.

Public awareness and health education: findings from an evaluation of health services for incontinence in England.

Improving the health and well being of local populations is a feature of international and national health policy and initiatives. Promotion of health has been attempted traditionally via health education and public awareness campaigns. More recently, attention has been drawn to inter-agency collaboration and alliances in formalised health improvement programmes. This study has evaluated health services for incontinence in two health authorities in England in relation to health education and public awareness. One health authority had an established continence service and the other did not. A convenience sample of self selecting respondents from an earlier postal survey were interviewed via the telephone (n=376). Significantly, more people in the health authority with a continence service than the one without received information on incontinence from within formal health services (p<0.001) and read about services in health centres and clinics (p<0.001), whereas people in the health authority without a continence service were more likely to obtain information on incontinence from local newspapers (p<0.01) and local chemist shops (p<0.01). People in the health authority without a continence service were significantly more likely to feel that services could be improved than those where there was a service (p<0.0001). Only a minority of people with incontinence had received information about their condition or related health care and services. The availability of a continence service significantly influenced the information received. More information on incontinence had been obtained from informal sources than formal health sources. Local initiatives on the availability of services and how to access them, as well as health education information on incontinence may be more effective in raising public awareness and should supplement national campaigns.

Female juvenile delinquents' pragmatic awareness of conversational interactions.

Standardized testing has shown that juvenile delinquents have a high incidence of communication problems; however, discourse analyses have failed to confirm pragmatic deficits. This study's purpose was to explore, using qualitative procedures, the pragmatic awareness of female juvenile delinquents concerning conversational interactions. The 45 participants engaged in small-group conversations about communication during multiple class periods. On-line field notes served as the data and were used to determine emerging patterns of verbal and nonverbal communication behaviors. Identified themes included (a) active listening; (b) body position; (c) eye contact, facial expressions, and gestures; (d) utterance types; (e) topics of conversation; (f) politeness and honesty; and (g) conversational management. Results suggested that juvenile delinquents can state many conventions governing conversational interactions; however, some do not always display interactional behaviors consistent with their pragmatic awareness. Discrepancies about pragmatic awareness are discussed in terms of the underlying nature of communication challenges in delinquent populations.

Visual awareness and the cerebellum: possible role of decorrelation control.

The two roles in awareness most often suggested for the cerebellum are (i) keeping the details of motor skills away from forebrain computation, and (ii) signaling to the forebrain when a sensory event is not predictable from prior motor commands. However, it is unclear how current models of the cerebellum could carry out these roles. Their architecture, based on the seminal ideas of Marr and Albus, appears to need 'motor error' to learn correct motor commands. However, since motor error is the difference between the actual motor command and what the command should have been, it is a signal unavailable to the organism in principle. We propose a possible solution to this problem, termed decorrelation control, in which the cerebellum learns to decorrelate the motor command sent to the muscles from the sensory consequences of motor error. This method was tested in a linear model of oculomotor plant compensation in the vestibulo-ocular reflex. A copy of the eye-movement command was sent as mossy-fiber input to the flocculus, represented as a simple adaptive filter version of the Marr-Albus architecture. The sensory consequences of motor error were retinal slip, delivered as climbing fiber input to the flocculus. A standard anti-Hebbian learning rule was used to decorrelate the two. Simulations of the linearized problem showed the method to be effective and robust for plant compensation. Decorrelation control is thus a candidate algorithm for the basic cerebellar microcircuit, indicating how it could achieve motor learning using only signals available to the system. Such learning might then enable the cerebellum to free up visual awareness, and also, by providing a sensory signal decorrelated from motor command, supply awareness with crucial information about the external world.

From synchronous neuronal discharges to subjective awareness?

For practical clinical purposes, as well as because of their deep philosophical implications, it becomes increasingly important to be aware of contemporary studies of the brain mechanisms that generate subjective experiences. Current research has progressed to the point where plausible theoretical proposals can be made about the neurophysiological and neurochemical processes which mediate perception and sustain subjective awareness. An adequate theory of consciousness must describe how information about the environment is encoded by the exogenous system, how memories are stored in the endogenous system and released appropriately for the present circumstances, how the exogenous and endogenous systems interact to produce perception, and explain how consciousness arises from that interaction. Evidence assembled from a variety of neuroscience areas, together with the invariant reversible electrophysiological changes observed with loss and return of consciousness in anesthesia as well as distinctive quantitative electroencephalographic profiles of various psychiatric disorders, provides an empirical foundation for this theory of consciousness. This evidence suggests the need for a paradigm shift to explain how the brain accomplishes the transformation from synchronous and distributed neuronal discharges to seamless global subjective awareness. This chapter undertakes to provide a detailed description and explanation of these complex processes by experimental evidence marshaled from a wide variety of sources.

Restoration of hypoglycaemia awareness in patients with long-duration insulin-dependent diabetes.

Hypoglycaemia without warning is a dangerous complication of insulin-dependent diabetes mellitus and it limits the use of intensified insulin therapy to reduce chronic diabetic complications. To investigate the possibility of restoring awareness; symptomatic, cognitive, and hormonal responses to controlled hypoglycaemia were studied in insulin-dependent diabetic patients with long disease duration (6 with good glycaemic control and 6 with poor control) before and after hypoglycaemia avoidance. At the start of the study, all had loss of hypoglycaemia awareness. Responses to the initial challenge were small (pooled area under curve [AUC] adrenaline 5.75 [SE 0.07] nmol/L per 260 min, pooled AUC symptom score 80 [1.3]) and only started when plasma glucose was significantly lower than the 2.8 (0.1) mmol/L at which cognitive function deteriorated. After 4.1 (1.1) months' scrupulous hypoglycaemia avoidance, hormone and symptom responses to the challenge were increased (AUC adrenaline 15.9 [0.1] nmol/L per 260 min, p = 0.01; AUC symptom score 275 [7], p < 0.001), starting at plasma glucose concentrations significantly higher than that causing cognitive dysfunction. Glycosylated haemoglobin did not deteriorate significantly. We conclude that the normal hierarchy of subjective awareness before cognitive dysfunction during hypoglycaemia can be restored by avoiding hypoglycaemia. This is independent of disease duration or initial metabolic control.

Awareness under anesthesia and the development of posttraumatic stress disorder.

Failure of general anesthesia to render a patient insensate, termed "awareness," is estimated to affect between 40,000 and 140,000 patients in the US each year. This study investigated the occurrence of post-traumatic stress disorder (PTSD) in subjects who reported a past episode of intraoperative awareness. We inquired about intraoperative and postoperative experiences and studied the relationship between various surgical experiences and currently meeting the diagnosis of PTSD. Sixteen postawareness subjects and 10 postgeneral anesthesia controls completed the Clinician Administered PTSD Scale (CAPS), a standardized clinical rating scale for PTSD, and a questionnaire about peri-operative experiences. Nine of 16 subjects (56.3%), a mean of 17.9 postoperative years, and no controls met diagnostic criteria for current PTSD (X(2)= 8.6, df = 1, P<.01). Common intraoperative experiences included an inability to communicate, helplessness, terror, and pain. Postawareness patients had significant postoperative distress related to feeling unable to communicate, unsafe, terrified, abandoned and betrayed. Perioperative dissociative experiences predicted having current PTSD. Being conscious during surgery is a traumatic event that may result in developing chronic PTSD. Further studies should include prospective designs of prevalence and long-term psychological, social, and overall health effects, and ways of preventing and treating awareness-induced PTSD.
