Spontaneous (non-traumatic) intracerebral haemorrhage (ICH) affects ~3.4 million people worldwide each year, causing ~2.8 million deaths. Many randomised controlled trials and high-quality observational studies have added to the evidence base for the management of people with ICH since the last European Stroke Organisation (ESO) guidelines for the management of spontaneous ICH were published in 2014, so we updated the ESO guideline. This guideline update was guided by the European Stroke Organisation (ESO) standard operating procedures for guidelines and the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework, in collaboration with the European Association of Neurosurgical Societies (EANS). We identified 37 Population, Intervention, Comparator, Outcome (PICO) questions and prioritised clinical outcomes. We conducted systematic literature searches, tailored to each PICO, seeking randomised controlled trials (RCT) – or observational studies when RCTs were not appropriate, or not available – that investigated interventions to improve clinical outcomes. A group of co-authors allocated to each PICO screened titles, abstracts, and full texts and extracted data from included studies. A methodologist conducted study-level meta-analyses and created summaries of findings tables. The same group of co-authors graded the quality of evidence, and drafted recommendations that were reviewed, revised and approved by the entire group. When there was insufficient evidence to make a recommendation, each group of co-authors drafted an expert consensus statement, which was reviewed, revised and voted on by the entire group. The systematic literature search revealed 115,647 articles. We included 208 studies. We found strong evidence for treatment of people with ICH on organised stroke units, and secondary prevention of stroke with blood pressure lowering. We found weak evidence for scores for predicting macrovascular causes underlying ICH; acute blood pressure lowering; open surgery via craniotomy for supratentorial ICH; minimally invasive surgery for supratentorial ICH; decompressive surgery for deep supratentorial ICH; evacuation of cerebellar ICH > 15 mL; external ventricular drainage with intraventricular thrombolysis for intraventricular extension; minimally invasive surgical evacuation of intraventricular blood; intermittent pneumatic compression to prevent proximal deep vein thrombosis; antiplatelet therapy for a licensed indication for secondary prevention; and applying a care bundle. We found strong evidence against anti-inflammatory drug use outside of clinical trials. We found weak evidence against routine use of rFVIIa, platelet transfusions for antiplatelet-associated ICH, general policies that limit treatment within 24 h of ICH onset, temperature and glucose management as single measures (outside of care bundles), prophylactic anti-seizures medicines, and prophylactic use of temperature-lowering measures, prokinetic anti-emetics, and/or antibiotics. New evidence about the management of ICH has emerged since 2014, enabling this update of the ESO guideline to provide new recommendations and consensus statements. Although we made strong recommendations for and against a few interventions, we were only able to make weak recommendations for and against many others, or produce consensus statements where the evidence was insufficient to guide clinical decisions. Although progress has been made, many interventions still require definitive, high-quality evidence, underpinning the need for embedding clinical trials in routine clinical practice for ICH.

Background: community-based complex interventions for older adults have a variety of names, including Comprehensive Geriatric Assessment, but often share core components such as holistic needs assessment and care planning. Objective: to summarise evidence for the components and effectiveness of community-based complex interventions for improving older adults’ independent living and quality of life (QoL). Methods: we searched nine databases and trial registries to February 2022 for randomised controlled trials comparing complex interventions to usual care. Primary outcomes included living at home and QoL. Secondary outcomes included mortality, hospitalisation, institutionalisation, cognitive function and functional status. We pooled data using risk ratios (RRs) or standardised mean differences (SMDs) with 95% confidence intervals (CIs). Results: we included 50 trials of mostly moderate quality. Most reported using holistic assessment (94%) and care planning (90%). Twenty-seven (54%) involved multidisciplinary care, with 29.6% delivered mainly by primary care teams without geriatricians. Nurses were the most frequent care coordinators. Complex interventions increased the likelihood of living at home (RR 1.05; 95% CI 1.00–1.10; moderate-quality evidence) but did not affect QoL. Supported by high-quality evidence, they reduced mortality (RR 0.86; 95% CI 0.77–0.96), enhanced cognitive function (SMD 0.12; 95% CI 0.02–0.22) and improved instrumental activities of daily living (ADLs) (SMD 0.11; 95% CI 0.01–0.21) and combined basic/instrumental ADLs (SMD 0.08; 95% CI 0.03–0.13). Conclusions: complex interventions involving holistic assessment and care planning increased the chance of living at home, reduced mortality and improved cognitive function and some ADLs.

Evidence of effective aphasia rehabilitation is emerging, yet intervention and delivery varies widely. This European Stroke Organisation guideline adhered to the guideline development standard procedures and Grading of Recommendations, Assessment, Development and Evaluation (GRADE) methodology. The resulting multi-disciplinary, evidence-based recommendations support the delivery of high-quality stroke-related aphasia rehabilitation. The working group identified 10 clinically relevant aphasia rehabilitation questions and rated outcomes’ relevance and importance. Following systematic searching, independent reviewers screened title-abstracts and full-texts for randomised controlled trials of speech-language therapy (SLT) for stroke-related aphasia. Results were profiled using PRISMA. Risk-of-bias was evaluated using the Cochrane Risk-of-Bias 1 tool. We prioritised final-value data. Where possible we conducted meta-analyses (RevMan) using random effects and mean, standardised mean differences (functional communication, quality of life, aphasia severity, auditory comprehension and spoken language outcomes) or odds ratios (adverse events). Using GRADE, we judged quality of the evidence (high-to-very low) and ESO recommendation strength (very strong-to-very weak). Where evidence was insufficient to support recommendations, expert opinions were described. Based on low-quality evidence we recommend the provision of higher total SLT dose (⩾20 h) and suggest higher SLT intensity and frequency to improve outcomes in aphasia rehabilitation. Similarly, we suggest the provision of individually-tailored SLT and digital and group therapy delivery models. Very low-level evidence for transcranial direct current stimulation (tDCS) with SLT informed the expert consensus that such interventions should only be provided in the context of high-quality trials. Evidence-based clinical-research priorities to inform SLT aphasia rehabilitation intervention choice and delivery are highlighted.

Background: The World Health Organization advocates integration of traditional and complementary medicine (T&CM) into the conventional health services delivery system. Integrating quality services in a patient-centred manner faces substantial challenges when T&CM is delivered within a health system dominated by conventional medicine. This review has synthesized international experiences of integration strategies across different contexts. Sources of data: Publications describing international experiences of delivering T&CM service in conventional healthcare settings were searched. Backward and forward citation chasing was also conducted. Areas of agreement: Capable leaders are crucial in seeking endorsement from stakeholders within the conventional medicine hierarchy and regulatory bodies. However, patient demands for integrative care can be successful as demonstrated by cases included in this review, as can the promotion of the use of T&CM for filling effectiveness gaps in conventional medicine. Safeguarding quality and safety of the services is a priority. Areas of controversy: Different referral mechanisms between conventional and T&CM practitioners suit different contexts, but at a minimum, general guideline on responsibilities across the two professionals is required. Evidence-based condition-specific referral protocols with detailed integrative treatment planning are gaining in popularity. Growing points: Interprofessional education is critical to establishing mutual trust and understanding between conventional clinicians and T&CM practitioners. Interprofessional communication is key to a successful collaboration, which can be strengthened by patient chart sharing, instant information exchange, and dedicated time for face-to-face interactions. Areas timely for developing research: Research is needed on the optimal methods for financing integrated care to ensure equitable access, as well as in remuneration of T&CM practitioners working in integrative healthcare.

Pattern diagnosis-guided treatments in Traditional Chinese Medicine (TCM) has been recognised by the eleventh revision of the International Classification of Diseases (ICD-11). Accurate pattern diagnosis requires reliable and valid diagnostic instruments that guide the collection of TCM clinical data without bias. This study synthesised the existing TCM diagnostic instruments for functional dyspepsia (FD) and appraised their quality regarding their development process and measurement properties. Seven electronic databases were searched for validation studies on TCM diagnostic instruments for FD. Synthesis and appraisal of the included studies were performed following the COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) Initiative guidelines adapted for TCM diagnostic instruments. Risk of bias assessment was conducted using the COSMIN Risk of Bias Checklist. Five studies were included, with five unique TCM diagnostic instruments for FD identified. All five diagnostic instruments were of inadequate quality in terms of their development process, implying a shortcoming in their relevance, comprehensibility, and comprehensiveness. Only the criterion validity of Stomach Qi Deficiency Pattern Assessment Scale was of sufficient quality and had no risk of bias in its validation. The quality of TCM diagnostic instruments for FD warrants urgent improvements. None of them was considered reliable or valid for guiding TCM pattern diagnosis. To support the evidence base of the standardization of TCM patterns in ICD-11, TCM diagnostic instruments should be developed and validated rigorously under the COSMIN guidelines. Amendments should be made on the guidelines to accommodate the features and uniqueness of TCM diagnostic process.
