Digital museum collections and social media: ethical considerations of ownership and use

This paper examines the role of digital collections and digital information in the democratisation process of museums. The paper focuses on ethical and ownership issues regarding Wikipedia’s online encyclopaedia initiative to widen access to digital images and knowledge through digital media, for the wider public. The paper draws on three cases of national museums in the UK, namely the Victoria and Albert Museum, the British Museum and the National Portrait Gallery. The paper argues that notions of governmentality, power, authority, and control - which traditionally characterise national museums - are still dominant in digital collections. This occasionally results in tensions that revolve around the issue of ownership of digital images and digital museum objects as well as their commercial and non-commercial uses. The paper shows that recent disputes and discourse related to the use of digital images by Wikipedians (active users of Wikipedia) have raised issues of authority and control not only of physical objects but also of the information and knowledge related to these objects. The paper demonstrates that the level of collaboration with Wikipedia reflects to some extent the participatory nature, philosophy, and ideology of each museum institution

China Stroke Surveillance Report 2021

Since 2015, stroke has become the leading cause of death and disability in China, posing a significant threat to the health of its citizens as a major chronic non-communicable disease. According to the China Stroke High-risk Population Screening and Intervention Program, an estimated 17.8 million [95% confidence interval (CI) 17.6–18.0 million] adults in China had experienced a stroke in 2020, with 3.4 million (95% CI 3.3–3.5 million) experiencing their first-ever stroke and another 2.3 million (95% CI 2.2–2.4 million) dying as a result. Additionally, approximately 12.5% (95% CI 12.4–12.5%) of stroke survivors were left disabled, as defined by a modified Rankin Scale score greater than 1, equating to 2.2 million (95% CI 2.1–2.2 million) stroke-related disabilities in 2020. As the population ages and the prevalence of risk factors like diabetes, hypertension, and hyperlipidemia continues to rise and remains poorly controlled, the burden of stroke in China is also increasing. A large national epidemiological survey initiated by the China Hypertension League in 2017 showed that the prevalence of hypertension was 24.7%; the awareness, treatment, and control rates in hypertensive patients were: 60.1%, 42.5%, and 25.4%, respectively. A nationally representative sample of the Chinese mainland population showed that the weighted prevalence of total diabetes diagnosed by the American Diabetes Association criteria was 12.8%, suggesting there are 120 million adults with diabetes in China, and the awareness, treatment, and control rates in diabetic patients were: 43.3%, 49.0%, and 49.4%, respectively. The “Sixth National Health Service Statistical Survey Report in 2018” showed that the proportion of the obese population in China was 37.4%, an increase of 7.2 points from 2013. Data from 1599 hospitals in the Hospital Quality Monitoring System and Bigdata Observatory Platform for Stroke of China (BOSC) showed that a total of 3,418,432 stroke cases [mean age ± standard error (SE) was (65.700 ± 0.006) years, and 59.1% were male] were admitted during 2020. Of those, over 80% (81.9%) were ischemic stroke (IS), 14.9% were intracerebral hemorrhage (ICH) strokes, and 3.1% were subarachnoid hemorrhage (SAH) strokes. The mean ± SE of hospitalization expenditures was Chinese Yuan (CNY) (16,975.6 ± 16.3), ranging from (13,310.1 ± 12.8) in IS to (81,369.8 ± 260.7) in SAH, and out-of-pocket expenses were (5788.9 ± 8.6), ranging from (4449.0 ± 6.6) in IS to (30,778.2 ± 156.8) in SAH. It was estimated that the medical cost of hospitalization for stroke in 2020 was CNY 58.0 billion, of which the patient pays approximately CNY 19.8 billion. In-hospital death/discharge against medical advice rate was 9.2% (95% CI 9.2–9.2%), ranging from 6.4% (95% CI 6.4–6.5%) for IS to 21.8% for ICH (95% CI 21.8–21.9%). From 2019 to 2020, the information about 188,648 patients with acute IS receiving intravenous thrombolytic therapy (IVT), 49,845 patients receiving mechanical thrombectomy (MT), and 14,087 patients receiving bridging (IVT + MT) were collected through BOSC. The incidence of intracranial hemorrhage during treatment was 3.2% (95% CI 3.2–3.3%), 7.7% (95% CI 7.5–8.0%), and 12.9% (95% CI 12.3–13.4%), respectively. And in-hospital death/discharge against medical advice rate was 8.9% (95% CI 8.8–9.0%), 16.5% (95% CI 16.2–16.9%), and 16.8% (95% CI 16.2–17.4%), respectively. A prospective nationwide hospital-based study was conducted at 231 stroke base hospitals (Level III) from 31 provinces in China through BOSC from January 2019 to December 2020 and 136,282 stroke patients were included and finished 12-month follow-up. Of those, over 86.9% were IS, 10.8% were ICH strokes, and 2.3% were SAH strokes. The disability rate [% (95% CI)] in survivors of stroke at 3-month and 12-month was 14.8% (95% CI 14.6–15.0%) and 14.0% (95% CI 13.8–14.2%), respectively. The mortality rate [% (95% CI)] of stroke at 3-month and 12-month was 4.2% (95% CI 4.1–4.3%) and 8.5% (95% CI 8.4–8.6%), respectively. The recurrence rate [% (95% CI)] of stroke at 3-month and 12-month was 3.6% (95% CI 3.5–3.7%) and 5.6% (95% CI 5.4–5.7%), respectively. The Healthy China 2030 Stroke Action Plan was launched as part of this review, and the above data provide valuable guidelines for future stroke prevention and treatment efforts in China

The role of 'confounding by indication' in assessing the effect of quality of care on disease outcomes in general practice: results of a case-control study.

BACKGROUND: In quality of care research, limited information is found on the relationship between quality of care and disease outcomes. This case-control study was conducted with the aim to assess the effect of guideline adherence for stroke prevention on the occurrence of stroke in general practice. We report on the problems related to a variant of confounding by indication, that may be common in quality of care studies. METHODS: Stroke patients (cases) and controls were recruited from the general practitioner's (GP) patient register, and an expert panel assessed the quality of care of cases and controls using guideline-based review criteria. RESULTS: A total of 86 patients was assessed. Compared to patients without shortcomings in preventive care, patients who received sub-optimal care appeared to have a lower risk of experiencing a stroke (OR 0.60; 95% CI 0.24 to 1.53). This result was partly explained by the presenc
