External quality monitoring facilitates improvement in already well-performing stroke units: insights from RES-Q Poland.

INTRODUCTION: The Registry of Stroke Care Quality (RES-Q) is used in Poland for quality monitoring by numerous hospitals participating in the Angels Initiative. Our aim was to assess the degree of improvement in highly stroke-oriented centres that report cases to the RES-Q each year. MATERIAL AND METHODS: This retrospective analysis included Polish stroke units that from January 2017 to December 2020 contributed to the RES-Q at least 25 patients annually. RESULTS: Seventeen out of 180 Polish stroke units reported patients each year (2017, n = 1,691; 2018, n = 2,986; 2019, n = 3,750; 2020, n = 3,975). The percentage of ischaemic stroke patients treated with alteplase remained stable (26%, 29%, 30% and 28%, respectively). The door-to-needle time progressively decreased, from a median 49 minutes to 32 minutes. The percentage of patients treated ≤ 60 minutes and ≤ 45 minutes significantly increased (from 68% to 86% and from 43% to 70%, respectively), with no change observed between 2019 and 2020. Despite a general improvement in dysphagia screening (81%, 91%, 98% and 99%), screening performed within the first 24h from admission became less frequent (78%, 76%, 69% and 65%). In-hospital mortality significantly increased (11%, 11%, 13% and 15%), while the proportion of patients discharged home remained stable. CONCLUSIONS: Quality-oriented projects facilitate the improvement of stroke care, even in centres demonstrating good baseline performance. Polish stroke units that consistently reported cases to the RES-Q demonstrated improvement in terms of door-to- -needle time and dysphagia screening. However, there is still a need to shorten the time to dysphagia screening, and carefully monitor stroke unit mortality following the COVID-19 pandemic.

Cervical dystonia - improving the effectiveness of botulinum toxin therapy.

INTRODUCTION: Cervical dystonia is the most frequent form of focal dystonia. It is characterised by involuntary muscular contractions resulting in abnormal head/neck and shoulder movements and postures, which can be associated with tremor and pain. Local intramuscular injections of botulinum toxin type A (BoNT-A) is the treatment of choice, being both effective and well-tolerated. However, a considerable number (c. 30%) of patients discontinue this treatment. The aim of this review was to analyse the factors possibly responsible for treatment failures of cervical dystonia (CD), with special regard to the new classification known as the 'Col-Cap' concept and non-motor symptoms. CLINICAL IMPLICATIONS: Several factors analysed in this review are responsible for effective treatment: proper diagnosis of dystonia and exclusion of pseudodystonias, correct recognition of dystonia pattern and identification of new patterns according to the Col-Cap concept, muscle selection and precise injections under electromyography (EMG) and/or ultrasonography (US) guidance. Furthermore, concomitant diagnosis and treatment of non-motor symptoms such as depression, anxiety, fatigue, sleep problems, phobias and stigmatisation are crucial in obtaining the best overall effect of the treatment. Primary and secondary immunisation and non-responsiveness seem to be marginal problems nowadays due to a low potential of new BoNT-A formulations to produce neutralising antibodies. FUTURE DIRECTIONS: There is a need for new and relevant scales combining the Col-Cap concept patterns with non-motor symptoms and quality of life. There is also a lack of specific rehabilitation protocols which could enhance BoNT-A treatment results.
