Headache service quality: evaluation of quality indicators in 14 specialist-care centres.

BACKGROUND: The study was a collaboration between Lifting The Burden (LTB) and the European Headache Federation (EHF). Its aim was to evaluate the implementation of quality indicators for headache care Europe-wide in specialist headache centres (level-3 according to the EHF/LTB standard). METHODS: Employing previously-developed instruments in 14 such centres, we made enquiries, in each, of health-care providers (doctors, nurses, psychologists, physiotherapists) and 50 patients, and analysed the medical records of 50 other patients. Enquiries were in 9 domains: diagnostic accuracy, individualized management, referral pathways, patient's education and reassurance, convenience and comfort, patient's satisfaction, equity and efficiency of the headache care, outcome assessment and safety. RESULTS: Our study showed that highly experienced headache centres treated their patients in general very well. The centres were content with their work and their patients were content with their treatment. Including disability and quality-of-life evaluations in clinical assessments, and protocols regarding safety, proved problematic: better standards for these are needed. Some centres had problems with follow-up: many specialised centres operated in one-touch systems, without possibility of controlling long-term management or the success of treatments dependent on this. CONCLUSIONS: This first Europe-wide quality study showed that the quality indicators were workable in specialist care. They demonstrated common trends, producing evidence of what is majority practice. They also uncovered deficits that might be remedied in order to improve quality. They offer the means of setting benchmarks against which service quality may be judged. The next step is to take the evaluation process into non-specialist care (EHF/LTB levels 1 and 2).

Evaluation of headache service quality indicators: pilot implementation in two specialist-care centres.

BACKGROUND: Evaluating quality of health care is increasingly recognized as an important contributor to the advancement of health-care delivery. We recently developed a set of quality indicators for headache care, intended to be applicable across countries, cultures and settings so that deficiencies in headache care worldwide might be recognized and rectified. These indicators themselves require evaluation and proof of fitness for purpose. This pilot study begins this process. METHODS: We tested the quality indicators in the tertiary headache centres of the University of Duisburg-Essen in Essen, Germany, and the Hospital da Luz in Lisbon, Portugal. Using seven previously-developed enquiry instruments, we interrogated health-care providers (HCPs), including doctors, nurses, psychologists and physiotherapists, as well as consecutive patients and their medical records. RESULTS: The questionnaires were easily understood by both HCPs and patients and were not unduly time-consuming. The results from the two headache centres were comparable despite their differences in structure, staffing and language. These findings met the purpose of the study. Diagnoses were made according to ICHD criteria and critically evaluated during follow-up. However, diagnostic diaries and instruments assessing burden and response to treatment were not always in place or routinely utilised. Triage systems adjusted waiting times to urgency of need. Treatment plans included pathways to other specialities. Patients felt welcomed, reassured and educated, and were mostly satisfied. Discussion points arose over inclusion of psychological therapies in treatment plans; over recording of outcomes; over indicators of efficiency and equitability (protocols to limit wastage of resources, systems to measure input costs and means of ensuring equal access to the services); and over protocols for reporting serious adverse events. CONCLUSION: This pilot study to assess feasibility of the methods and acceptability of the instruments of headache service quality evaluation was successful. The project is ready to be taken into its next stages.

Persistent monocular visual loss in migraine patients.

The relationship between migraine and vision is complex. Besides migraine aura status and persistent visual aura without infarction, recognized by International Headaches Classification 3, cases of persistent monocular alterations have been described in migraineurs. To discuss the role of migraine as a risk factor for persistent monocular visual loss. We present five new cases of persistent monocular visual loss in migraineurs, discuss the differential diagnosis and possible relationship with migraine. Five young healthy patients are reported (three women) with a history of migraine (four with visual aura), that developed persistent monocular visual defects, four during an episode of migraine with aura. All patients were submitted to an extensive investigation. In three patients the scotoma was identified on automated perimetry; one of these patients had retinal hemorrhagic lesions, with fluorescein angiography revealing an isolated retinal vasculitis. In two patients fundoscopy revealed transient cotton wools spots. Except for the patient with retinal vasculitis, etiologic investigation was not conclusive. Monocular visual loss can occur in the setting of multiple pathologies that affect the eye and related structures. Although diseases requiring emergent intervention should always be excluded, we propose migraine should be considered as a contributing factor for unexplained monocular persistent scotoma.Monocular visual loss can occur in the setting of multiple pathologies that affect the eye and related structures.

MoCA as a cognitive assessment tool for absence status epilepticus.

De novo absence status is clinically characterized by a confusional syndrome and neurophysiologically by the presence of periodic spike/polyspike-and-wave discharges on EEG. The treatment should be started promptly, and fast recovery is usually seen. However, cognitive symptoms can be very difficult to detect, and no consensus exists on how cognitive improvement can be clinically monitored. We report a patient with absence status epilepticus, whose therapeutic response was monitored neurophysiologically with EEG and clinically with a cognitive test; the Montreal Cognitive Assessment (MoCA). Based on this case report, we describe the use of the MoCA for monitoring cognitive function in a patient with absence status epilepticus. MoCA was evaluated on three occasions, with a total score ranging from 9, before treatment, to 23, when an EEG with no epileptiform discharges was obtained. We suggest that MoCA may be a useful tool to monitor cognitive improvement in absence status epilepticus.

Kinesiophobia in migraine.

UNLABELLED: Pain aggravation by movement and avoidance of movement (kinesiophobia) is often reported by patients during migraine attacks. Yet its specific contribution to migraine diagnosis is undetermined. To characterize the frequency and severity of kinesiophobia during migraine and its role in the diagnosis of primary headaches, we questioned 150 patients (126 women and 24 men, average age 38.5 yrs) with migraine (n = 111) or tension-type headache (TTH) (n = 39) about aggravation of pain by bending forward, brisk head movements (jolt), and avoidance of movement during the attacks. The degree of pain worsening by each stimulus was measured through a visual analog scale and compared to worsening produced by other sensory stimuli such as light, sound, and smell. The discrimination power of kinesiophobia between migraine and TTH was calculated, using the International Classification of Headache Disorders criteria as gold standard. Sensitivity/specificity of studied symptoms was high in differentiating the 2 headache types: bending forward: 98%/85.7%; jolt: 96.3%/81.6%; and immobility during the attacks: 100%/70%. The degree of kinesiophobia was identical to photo- and phonophobia in migraine patients. We conclude that kinesiophobia discriminates between migraine and TTH. Bending forward and jolt may be useful additional questions to ask patients for the differentiation of headache attacks. PERSPECTIVE: This article evaluates the specific role of movement (movement-induced pain aggravation and avoidance of movement) in primary headaches. Kinesophobia is an easy symptom to screen, explained by migraine pathophysiology, and proved to be a sensitive and specific measure to identify migraine attacks when compared to tension-type headache.

Evidence for central abnormality in respiratory control in primary lateral sclerosis.

Primary lateral sclerosis (PLS) is a very rare disease characterized by pure upper motor neuron findings. Although a number of previous reports have evaluated this condition, no study has addressed the respiratory function in PLS. Six patients meeting previously proposed diagnostic criteria for PLS were submitted to a number of respiratory tests: forced vital capacity, maximal pressures, phrenic nerve responses, needle electromyography of the respiratory muscles, percutaneous nocturnal oximetry (PNO) and polysomnography (two patients). Our results show that the diaphragm is not affected in this condition, but some respiratory function tests (RFT) and PNO had abnormal values. Voluntary muscular activation to perform RFT may be limited in these patients. PNO and polysomnography suggest that respiratory central drive dysfunction can occur when upper motor neurons are severely affected, in PLS. However, we did not verify progression on follow-up.

Autonomic features in cluster headache. Exploratory factor analysis.

The objective is to identify the pathogenesis of each autonomic manifestation in cluster headache (CH). Through a deductive statistics method (factor analysis) we analysed the type of autonomic symptoms reported by 157 CH patients. Three principal components were identified in the analysis: parasympathetic activation (lacrimation, conjunctival injection and rhinorrhoea), sympathetic defect (miosis and ptosis) and parasympathetic mediated effect (nasal congestion, eyelid oedema and forehead sweating). This work suggests that there are three different mechanisms underlying autonomic manifestations in CH.
