A multidisciplinary guideline for the acute phase of stroke: barriers perceived by Dutch neurologists.

RATIONALE, AIMS AND OBJECTIVES: Guidelines for stroke management should improve quality of care. Dissemination of guidelines, however, does not guarantee guideline adherence. The aim of this paper is to investigate barriers for guideline adherence to bring about suggestions for possible implementation strategies. METHOD: Questionnaire survey among all Dutch neurologists working on neurology wards in general hospitals during the year 2000 in The Netherlands. RESULTS: The neurologists expressed a high degree of agreement with the diagnostic and preventive recommendations, but expressed doubts with regard to the therapeutic recommendations, especially for the recombinant tissue plasminogen activator therapy. In general, barriers at the organizational and the multidisciplinary team level were most prominent. CONCLUSIONS: Active implementation of the guidelines seems necessary. Implementation strategies should be focused on the different sources of barriers: the caregiver, the patient and the organization of care.

Variation in the use of angiography and carotid endarterectomy by neurologists in the UK-TIA aspirin trial.

Of 959 patients with complete records at entry to the UK-TIA Aspirin Trial 32% underwent angiography; for the 27 neurologists with 10 or more patients in the trial this rate varied from 3% to 100%. Seven per cent of the patients had carotid surgery; similarly the rate varied from 0% to 25% depending on the policy of the neurologist. These differences may be partly due to different perceptions of the safety and usefulness of carotid surgery. Ten of 41 (24%) patients undergoing carotid surgery after randomisation had a perioperative stroke, and four of them died.

Attitudes of neurologists, psychiatrists, and psychotherapists towards predictive testing for Huntington's disease in Germany.

Predictive testing for Huntington's disease (HD) in Germany is performed by genetic counsellors, neurologists, psychiatrists, and psychotherapists. In order to evaluate the attitudes of neurologists, psychiatrists, and psychotherapists in Germany towards predictive testing for HD, a postal questionnaire was sent to this group. Two German Bundesländer were chosen, Baden Württemberg (BW) and Niedersachsen (NS). Of 469 persons interviewed the response rate was 32.6%. The questionnaire consisted of 17 items assessing sociodemographic data, acquaintance with HD patients, lay organisations, attitudes towards genetic counselling, presymptomatic and prenatal DNA testing, and reproduction of persons at risk for HD. More than 70% of the subjects were well informed about predictive DNA testing but knowledge about the details of the test procedure, especially the World Federation of Neurology (WFN) and International Huntington Association (IHA)1 recommendations, was quite low (11.8%). Nevertheless, the majority would recommend predictive testing for HD although they anticipated problems for the probands. The majority of our respondents favoured psychological test and post-test counselling for those tested. Concerning reproduction, most subjects favoured prenatal testing or that persons at risk should refrain from having children. We found that the opinions of practitioners and at risk persons differed with respect to the predictive DNA test and, particularly, to prenatal testing. Therefore the testing procedure could be improved if practitioners were better informed about the DNA test in general and about the attitudes and wishes of their patients.

Ability of a nurse specialist to diagnose simple headache disorders compared with consultant neurologists.

OBJECTIVE: To compare the ability of a headache nurse specialist and consultant neurologists in diagnosing tension-type headache and migraine. METHODS: An experienced neurology ward sister was trained in the differential diagnosis of headache disorders. Over six months, patients with non-acute headache disorders and role players trained to present with benign or sinister headaches were seen by both the nurse and a consultant neurologist. Both reached independent diagnoses of various headache disorders. RESULTS: Consultants diagnosed 239 patients with tension-type headache (47%), migraine (39%), or other headache disorders (14%). The nurse agreed with the consultant in 92% of cases of tension-type headache, 91% of migraine, and 61% of other diagnoses. Where the nurse did not agree with the diagnosis, most would have been referred for a consultant opinion. Both the nurse and the doctors misdiagnosed the same three of 13 role players. The investigation rate of the consultants varied between 18% and 59%. Only one clinically relevant abnormality was found on head scans and this was strongly suspected clinically. CONCLUSIONS: A headache nurse specialist can be trained to diagnose tension-type headache and migraine. A nationwide nurse led diagnostic headache service could lead to substantial reduction in neurology waiting times.

Diagnosis of motor neuron disease by neurologists: a study in three countries.

Ninety four neurologists in the United Kingdom, China, and West Germany responded to two structured questionnaires. The first assessed the diagnostic weighting assigned to a number of symptoms, signs, and clinical investigations ascertained from classical descriptions and case notes of patients with motor neuron disease (MND). The second tested the likelihood and consistency of diagnosis in a series of case summaries representing the clinical data of 10 patients with clinically and pathologically documented motor neuron disease. There was a wide measure of agreement concerning the common clinical features of the disease, especially regarding fasciculation of the tongue, fasciculation associated with weakness seen in more than one limb, and dysphagia. In the case summaries, however, there was clear variation in the ranked likelihood of the diagnosis of MND and in the consistency of diagnostic behaviour in the different groups of neurologists. These findings support the need for internationally agreed criteria in the diagnosis of MND. Any such criteria will need to be tested against a standardised data set to establish their validity.

The neurologist and Harvard criteria for brain death.

The Harvard ad hoc committee to examine the definition of brain death, chaired by anesthesiologist Beecher, published their report in 1968. Throughout the years, the committee has been a target of criticism. However, the workings of the ad hoc committee have not been carefully evaluated, and could provide insight into the role of the neurologists and their interaction with contemporaries. Review of the original files and interviews with three surviving members-Adams, Potter, and Murray-revealed 1) a major role and original contributions of the neurologists Schwab and Adams in defining criteria, and 2) a swift and decisive working committee that formulated a document aimed at simplicity and accuracy, and without special interest.

Neurologists for patient safety: where we stand, time to deliver.

Neurologists have a professional opportunity, an ethical responsibility, and sound clinical and economic reasons for engaging in efforts to improve patient safety. Better communication with patients and other providers, closer follow-up of consultation cases, and more focused supervision of trainees will help to reduce current patterns of error and misunderstanding. Patient education with attention to health literacy should improve adherence to management plans and help to bridge transitions of care across providers and sites. Through teaching and by example, neurologists can profoundly influence successive generations of clinicians to adopt safer practices, a culture of openness, and enhanced professionalism. The federal Safety and Quality Improvement Act of 2005, once implemented, should increase the evidence basis for safer care through voluntary, legally protected reporting of errors and adverse events within the framework of patient safety organizations.

A prospective study of principal care among Colorado neurologists.

We initially surveyed the practice patterns of 24 private sector neurologists in Colorado between June and September, 1985, having chosen representative practices from each of 4 practice types (solo [6], nonsolo single discipline [11], nonsolo multispecialty [4], and nonsolo HMO [3]) and from both urban (14) and rural (10) practice locations. Among 2,373 consecutive new patient visits initially surveyed, we reexamined 2,359 (99%) charts 1 year later to investigate patterns of principal care. We defined principal care as 2 or more follow-up visits in the year following the initial office visit. One-fifth of initial visits received principal care, and the mean number of follow-up visits per year among those receiving principal care was 4 (range, 2 to 32 visits). The best indicators of principal care were Medicare coverage, a classic neurologic diagnosis (seizure, stroke), rural practice location, and solo neurology practice. The best indicators of consultative care were self-pay coverage, a diagnosis of musculoskeletal, psychiatric, or pain disorder, urban practice location, and HMO neurology practice. Age, sex, race, and type of referring physician were unimportant in determining subsequent principal care. Projections of future manpower needs must reflect both consultative as well as principal care services provided by neurologists, as well as the cost-effectiveness of such care.

Neurologic complications following chiropractic manipulation: a survey of California neurologists.

To obtain an estimate of how often practicing neurologists in California encounter unexpected strokes, myelopathies, or radiculopathies following chiropractic manipulation, we surveyed each member of the American Academy of Neurology in California and inquired about the number of patients evaluated over the preceding 2 years who suffered a neurologic complication within 24 hours of chiropractic manipulation. Four hundred eighty-six neurologists were surveyed, 177 responded; 55 strokes, 16 myelopathies, and 30 radiculopathies were reported. Patients were between the ages of 21 and 60, and the majority experienced complications following cervical manipulation. Most of the patients continued to have persistent neurologic deficits 3 months after the onset, and about one-half had marked or severe deficits. Nearly all of the strokes involved the posterior circulation and almost one-half were angiographically proven. Patients, physicians, and chiropractors should be aware of the risk of neurologic complications associated with chiropractic manipulation.

Neurologists' attitudes regarding rt-PA for acute ischemic stroke.

We studied the attitudes of 238 Texas neurologists regarding the use of recombinant tissue plasminogen activator (rt-PA). The results show that 38 (16%) had treated stroke patients with rt-PA, and 97% of these would do so again. In the group that had not treated patients, 60% would treat if a suitable candidate presented. We conclude that soon after FDA approval of rt-PA, two-thirds of survey respondents were using or were planning to use this therapy. Those neurologists who have used rt-PA for stroke report a positive experience.

Ischemic stroke: outcomes, patient mix, and practice variation for neurologists and generalists in a community.

A variety of methods was used to compare patient mix, practice variation, survival, and recurrence after first ischemic stroke among Rochester, MN residents. The significance of the results for neurologists and generalists was examined. Age, stroke severity, congestive heart failure (CHF), and the interaction between atrial fibrillation and patient groups were determinants of survival. Without atrial fibrillation, patients on neurology services and patients on general services with neurology consultation had better survival than those without neurology consultation, adjusting for age, stroke severity, and CHF. With atrial fibrillation, patients on general services with neurology consultation had no better survival compared with those without neurology consultation; patients on neurology services had worse survival (p=0.002). There was no difference in stroke recurrence. Evaluation by a neurologist is associated with better survival for most patients with ischemic stroke but not those with atrial fibrillation. Only a randomized trial can determine whether this association is causal.

Pain medicine education among American neurologists: a need for improvement.

To assess pain medicine education, surveys were mailed to practicing neurologists (PNs) and residency program directors (PDs). Thirty percent of PNs felt adequately trained to diagnose and 20% to treat pain disorders. PNs stated that more pain education is needed for resident training (89%) and for PNs (91%). PDs ranked the importance of a pain subspecialty seventh out of eight subspecialties; only 29% reported having a neurology pain specialist on the faculty. These data strongly suggest a need to improve the pain medicine education of neurologists.

Results of carotid endarterectomy with prospective neurologist follow-up.

BACKGROUND: Previous studies have shown that neurologic complications following carotid endarterectomy (CE) are underestimated if patients are not examined by neurologists after surgery. OBJECTIVE: To review the morbidity and mortality in a cohort of patients examined before and after CE in a neurology and stroke clinic. METHODS: This was a prospective case series from an academic medical center; 44 patients were referred for CE during the period June 1995 to April 1999. Mean age was 64.3 years; 70.5% were referred for symptomatic stenosis and 29.5% were asymptomatic. Three neurosurgeons and two vascular surgeons operated on the patients. RESULTS: The 30-day mortality rate was 4.5% and the 30-day stroke or death rate was 11.4%. One patient had a TIA due to thrombus formation at the operative site and a second patient had an asymptomatic intimal flap. CONCLUSIONS: With prospective follow-up by neurologists, the CE complication rate in an academic medical center was significantly higher than the rates reported in controlled clinical trials. The generalizability of data from CE clinical trials is limited and local audits are necessary to better establish the risk/benefit ratio for individual hospitals and surgeons.

The cost-effectiveness of teleneurology consultations for patients admitted to hospitals without neurologists on site. 1: A retrospective comparison of the case-mix and management at two rural hospitals.

We are currently evaluating the use of telemedicine for improving the care of patients admitted with neurological symptoms to hospitals that do not have specialist neurologists on site. To do this we have been comparing the outcome of patients admitted to two small hospitals. In one hospital all patients with neurological symptoms are seen by a neurologist at a distance using an interactive video-link transmitting at 384 kbit/s; in the other patients with neurological problems are managed as per usual practices. For the results of this study to be valid, it is essential that the case-mix and process of management for neurological patients are similar at the two hospitals. We therefore compared the case-mix, process of management, and outcome for all patients admitted over a four-month period to either hospital who had been coded using ICD-10 as having a final diagnosis of a neurological condition. No appreciable differences were noted between the two hospitals for measures of case-mix or outcome. Likewise, most measures of process were similar, although there was a significant difference for the overall length of hospital episode between the two hospitals. When patients with prolonged hospital episodes were excluded, or only patients with a diagnosis of headache, epilepsy or transient ischaemic attack were considered (who as a group made up the bulk of neurological admissions), the difference in the length of hospital episode was not significant. It should therefore be possible for us to estimate the effect of telemedicine on the management of patients with neurological problems.

Role of the neurologist in hazard identification and risk assessment.

This review describes strategies used by a clinical neurologist in the investigation of neurotoxic disease. It emphasizes the need for a high level of suspicion that environmental substances are capable of producing impairments in neurologic and neurobehavioral functions. Because of the difficulties in differentiating neurotoxic from nonneurotoxic disease when presented with common neurological symptoms, it is necessary to rely upon corroborative evidence from past medical records, work and environmental histories, and exposure data, as well as detailed neurological examinations, to reach a conclusion about causation. Sensitive electrophysiologic and neuropsychologic test batteries are useful in identifying subclinical impairments and in providing objective confirmation of abnormalities in the central and peripheral nervous systems. Combining scientific and epidemiologic information with experience and clinical judgment, these sources of information are used in the formulation of a clinical diagnosis. When many patients among a group of people are exposed to neurotoxicants, the effects of the exposure may vary from one to another because of differences in susceptibility, duration of exposure and dosage of neurotoxicant, and other possible risk factors. Group statistics may obscure a significant effect for the larger group, despite clinically obvious effects in an individual. The neurologist applies clinical skills and refers to the accumulated neurotoxicologic literature as a frame of reference to make a diagnosis about an individual patient or a group of patients who have been exposed to particular neurotoxicants. The Boston University Environmental Neurology Assessment (BUENA) is a scheme that attempts to combine epidemiologic methodology and clinical approaches to detect effects of neurotoxic exposure. The advantages and limitations of such a strategy are discussed.

[Which patients does the neurologist assist? Basis for a curriculum in neurology].

OBJECTIVE: To present the most frequent diagnosis of patients referred to a neurologist and to discuss the importance of this finding for the definition of the curriculum in Neurology. BACKGROUND: The development of subspecialties of Neurology is interfering in the definition of what should be taught to train a physician or a neurologist. The knowledge of which are the most common neurological diseases may contribute to construct these curricula. METHOD: The initial diagnosis in 1815 outpatients referred to the neurologic service of an university-affiliated public hospital in São Paulo, Brazil, were analyzed. RESULTS: The most common diagnosis, in decreasing order of frequency were: headache, epilepsy, mental disorders, cerebrovascular disease, head injury, polyneuropathy, vestibular syndrome, spastic crural paraparesis, extrapyramidal syndrome, dementia, intracranial hypertension and facial palsy. CONCLUSION: The importance of the subspecialties in the curriculum should be related to the frequency of the neurologic diseases in the community.

Role of the neurologist in the evaluation and treatment of patients with trigeminal neuralgia.

The neurologist, although not usually the first healthcare provider to evaluate a patient with trigeminal neuralgia (TN), is often involved in confirming the diagnosis and managing the patient's pain with medications. The neurologist has several other important roles for patients with TN: assessing and reducing the individual's pain, patient and family education, and encouraging referral to a neurosurgeon for pain-reducing procedures when appropriate. In general, surgical procedures for TN should be considered when the patient does not attain pain relief after adequate trials of two or three medications, or when pain relief is attained but the patient requires medication dosing at levels that result in significant drug toxicity. There is emerging evidence that surgical procedures for TN are more effective if performed earlier in the course of the patient's pain.

[The importance of headaches in neurology clinics. Study groups of neurologists of Aragon].

OBJECTIVE: To analyze the patients sent to Neurology Clinics for headache and to investigate the differences in epidemiology, clinical findings and therapeutics as compared with those consulting for other neurological disorders. PATIENTS AND METHODS: Eighteen neurologists from all the Outpatient Departments of the Community of Aragon Health Service were analysed using a specially designed questionnaire for all the patients who attended the Neurology Clinics for the first time during a period of three months. RESULTS: Of 3,489 patients assessed, 25.5% complained of headache. Of these, 70% were women of an average age of 41.2 +/- 18.8 years. In 42% the consultation was for migraine followed by chronic tension headache in 30.1%. Family doctors sent 86.7% of the patients and requested complementary tests for 31.1%. Cerebral TAC (12.4%) and EEG (7.6%) were the investigations most often requested. Treatment was given to 68.6% of the patients with headache. Calcium-antagonists and anti-depressants were the drugs most used. CONCLUSIONS: Headache is the commonest cause for consulting a neurologist. It affects young adults, with marked predominance of the female sex. There are significative differences in clinical attention (fewer complementary tests are requested and less follow-up is necessary, although more treatment is given) than for other neurology patients.
