Impact of the COVID-19 pandemic on care-quality outcomes in older adults admitted to hospital with altered mental status.

OBJECTIVES: During the coronavirus disease (COVID-19) pandemic, patients with altered mental status (AMS: dementia, delirium and delirium superimposed on dementia) were profoundly affected by an abrupt transformation in healthcare systems. Here, we evaluated quality-care outcomes, including length of stay (LOS), in-hospital mortality, early readmission and mortality after hospital discharge, in older adults admitted for AMS during the pandemic and compared them to patients admitted prior to the pandemic. METHODS: Chi-squared and Fisher's exact tests were used to examine changes to admissions for AMS before and during the pandemic, and their outcomes. Logistic regression analyses, with reference to pre-pandemic data, were conducted to examine the impact of the pandemic on outcomes. DESIGN: Prospective data of 21,192 non-COVID admissions to an acute general medical department in a Surrey (UK) hospital were collected from patients admitted before (1st April 2019 to 29th February 2020) and during the pandemic (1st March 2020 to 31st March 2021). RESULTS: There were 10,173 (47.7% men) from the pre-pandemic and 11,019 (47.5% men) from the pandemic periods; overall mean age  =  68.3yr. During the pandemic AMS patients had significantly higher admission rates (1.1% vs 0.6%, P < 0.001). However, median LOS in hospital was shorter (9.0 days [IQR = 5.3-16.2] vs 15.5 days [IQR  =  6.2-25.7], P < 0.001) and thus were less likely to stay in hospital >3 weeks: adjusted OR  =  0.26 (95%CI  =  0.12-0.57). In-hospital mortality and readmission within 28 days of discharge did not change during the pandemic, but were less likely to die within 30 days of discharge: adjusted OR = 0.32 (95%CI = 0.11-0.96). CONCLUSIONS: This combination of higher admission rate, shorter LOS, and an unchanging early readmission suggests a higher admission-discharge turnover of different patients with AMS and provides important insights into the potential impact of the COVID-19 pandemic on healthcare delivery to individuals with AMS.

Evidence-based definition of hypoprolactinemia in European men aged 40-86 years: the European male ageing study.

Empirical evidence for a low normal or reference interval for serum prolactin (PRL) is lacking for men, while the implications of very low PRL levels for human health have never been studied. A clinical state of "PRL deficiency" has not been defined except in relation to lactation. Using data from the European Male Ageing Study (EMAS), we analyzed the distribution of PRL in 3,369 community-dwelling European men, aged 40-80 years at phase-1 and free from acute illnesses. In total, 2,948 and 2,644 PRL samples were collected during phase-1 and phase-2 (3 to 5.7 years later). All samples were analysed in the same centre with the same assay. After excluding individuals with known pituitary diseases, PRL ≥ 35 ng/ml, and PRL-altering drugs including antipsychotic agents, selective serotonin reuptake inhibitors, or dopamine agonists, 5,086 data points (2,845 in phase-1 and 2,241 in phase-2) were available for analysis. The results showed that PRL declined minimally with age (slope = -0.02) and did not correlate with BMI. The positively skewed PRL distribution was log-transformed to a symmetrical distribution (skewness reduced from 13.3 to 0.015). Using two-sigma empirical rule (2[]SD about the mean), a threshold at 2.5% of the lower end of the distribution was shown to correspond to a PRL value of 2.98ng/ml. With reference to individuals with PRL levels of 5-34.9 ng/ml (event rate = 6.3%), the adjusted risk of developing type 2 diabetes increased progressively in those with PRL levels of 3-4.9 ng/ml: event rate = 9.3%, OR (95% CI) 1.59 (0.93-2.71), and more so with PRL levels of 0.3-2.9 ng/ml: event rate = 22.7%, OR 5.45 (1.78-16.62). There was also an increasing trend in prediabetes and diabetes based on fasting blood glucose levels was observed with lower categories of PRL. However, PRL levels were not associated with cancer, cardiovascular diseases, depressive symptoms or mortality. Our findings suggest that a PRL level below 3 ng/ml (64 mlU/l) significantly identifies European men with a clinically-important outcome (of type 2 diabetes), offering a lower reference-value for research and clinical practice.

Sex-specific independent risk factors of urinary incontinence in acute stroke patients: A multicentre registry-based cohort study.

BACKGROUND: The presence of urinary incontinence (UI) in acute stroke patients indicates poor outcomes in men and women. However, there is a paucity and inconsistency of data on UI risk factors in this group and hence we conducted a sex-specific analysis to identify risk factors. METHODS: Data were collected prospectively (2014-2016) from the Sentinel Stroke National Audit Program for patients admitted to four UK hyperacute stroke units. Relevant risk factors for UI were determined by stepwise multivariable logistic regression, presented as odds ratios (OR) and 95% confidence intervals (CI). RESULTS: The mean (±SD) age of UI onset in men (73.9 year ± 13.1; n = 1593) was significantly earlier than for women (79.8 year ± 12.9; n = 1591: p < 0.001). Older age between 70 and 79 year in men (OR = 1.61: CI = 1.24-2.10) and women (OR = 1.55: CI = 1.12-2.15), or ≥80 year in men (OR = 2.19: CI = 1.71-2.81), and women (OR = 2.07: CI = 1.57-2.74)-reference: <70 year-both predicted UI. In addition, intracranial hemorrhage (reference: acute ischemic stroke) in men (OR = 1.64: CI = 1.22-2.20) and women (OR = 1.75: CI = 1.30-2.34); and prestroke disability (mRS scores ≥ 4) in men (OR = 1.90: CI = 1.02-3.5) and women (OR = 1.62: CI = 1.05-2.49) (reference: mRS scores < 4); and stroke severity at admission: NIHSS scores = 5-15 in men (OR = 1.50: CI = 1.20-1.88) and women (OR = 1.72: CI = 1.37-2.16), and NIHSS scores = 16-42 in men (OR = 4.68: CI = 3.20-6.85) and women (OR = 3.89: CI = 2.82-5.37) (reference: NIHSS scores = 0-4) were also significant. Factors not selected were: a history of congestive heart failure, hypertension, atrial fibrillation, diabetes and previous stroke. CONCLUSIONS: We have identified similar risk factors for UI after stroke in men and women including age >70 year, intracranial hemorrhage, prestroke disability and stroke severity.

Impact of healthcare-associated infections within 7-days of acute stroke on health outcomes and risk of care-dependency: a multi-centre registry-based cohort study.

Healthcare-associated infections (HCAIs) in patients admitted with acute conditions remain a major challenge to healthcare services. Here, we assessed the impact of HCAIs acquired within 7-days of acute stroke on indicators of care-quality outcomes and dependency. Data were prospectively collected (2014-2016) from the Sentinel Stroke National Audit Programme for 3309 patients (mean age = 76.2 yr, SD = 13.5) admitted to four UK hyperacute stroke units (HASU). Associations between variables were assessed by multivariable logistic regression (odds ratios, 95% confidence intervals), adjusted for age, sex, co-morbidities, pre-stroke disability, swallow screening, stroke type and severity. Within 7-days of admission, urinary tract infection (UTI) and pneumonia occurred in 7.6% and 11.3% of patients. Female (UTI only), older age, underlying hypertension, atrial fibrillation, previous stroke, pre-stroke disability, intracranial haemorrhage, severe stroke, and delay in swallow screening (pneumonia only) were independent risk factors of UTI and pneumonia. Compared to patients without UTI or pneumonia, those with either or both of these HCAIs were more likely to have prolonged stay (> 14-days) on HASU: 5.1 (3.8-6.8); high risk of malnutrition: 3.6 (2.9-4.5); palliative care: 4.5 (3.4-6.1); in-hospital mortality: 4.8 (3.8-6.2); disability at discharge: 7.5 (5.9-9.7); activity of daily living support: 1.6 (1.2-2.2); and discharge to care-home: 2.3 (1.6-3.3). In conclusion, HCAIs acquired within 7-days of an acute stroke led to prolonged hospitalisation, adverse health consequences and risk of care-dependency. These findings provide valuable information for timely intervention to reduce HCAIs, and minimising subsequent adverse outcomes.

Urinary incontinence indicates mortality, disability, and infections in hospitalised stroke patients.

OBJECTIVES: To assess the impact of urinary incontinence (UI) on health outcomes over the entire spectrum of acute stroke severity (National Institutes of Health Stroke Scale [NIHSS] scores: 0-42), due to a paucity of data on patients with milder strokes. PATIENTS AND METHODS: Data were prospectively collected (2014-2016) from the Sentinel Stroke National Audit Programme (1593 men, 1591 women; mean [SD] age 76.8 [13.3] years) admitted to four UK hyperacute stroke units (HASUs). Relationships between variables were assessed by multivariable logistic regression. Data were adjusted for age, sex, comorbidities, pre-stroke disability and intra-cranial haemorrhage, and presented as odds ratios with 95% confidence intervals. RESULTS: Amongst patients with no symptoms or a minor stroke (NIHSS scores of 0-4), compared to patients without UI, patients with UI had significantly greater risks of poor outcomes including: in-hospital mortality; disability at discharge; in-hospital pneumonia; urinary tract infection within 7 days of admission; prolonged length of stay on the HASU; palliative care by discharge; activity of daily living (ADL) support, and new discharge to care home. In patients with more moderate stroke (NIHSS score of 5-15) the same outcomes were identified; being at greater risk for patients with UI, except for palliative care by discharge and ADL support. With the highest stroke severity group (NIHSS score of 16-48) all outcomes were identified except in-patient mortality, pneumonia, and ADL support. However, odds ratios diminished as NIHSS scores increased. CONCLUSIONS: Urinary incontinence is a useful indicator of poor short-term outcomes in older patients with an acute stroke, but irrespective of stroke severity. This provides valuable information to healthcare professionals to identify at-risk individuals.

Diabetes mellitus and obesity among South Asians with ischemic stroke across three countries.

BACKGROUND: Diabetes mellitus and central obesity are more common among South Asian populations than among White British people. This study explores the differences in diabetes and obesity in South Asians with stroke living in the United Kingdom, India, and Qatar compared with White British stroke patients. METHODS: The study included the UK, Indian, and Qatari arms of the ongoing large Bio-Repository of DNA in Stroke (BRAINS) international prospective hospital-based study for South Asian stroke. BRAINS includes 4580 South Asian and White British recruits from UK, Indian, and Qatar sites with first-ever ischemic stroke. RESULTS: The study population comprises 1751 White British (WB) UK residents, 1165 British South Asians (BSA), 1096 South Asians in India (ISA), and 568 South Asians in Qatar (QSA). ISA, BSA, and QSA South Asians suffered from higher prevalence of diabetes compared with WB by 14.5% (ISA: 95% confidence interval (CI) = 18.6-33.0, p < 0.001), 31.7% (BSA: 95% CI = 35.1-50.2, p < 0.001), and 32.7% (QSA: 95% CI = 28.1-37.3, p < 0.001), respectively. Although WB had the highest prevalence of body mass index (BMI) above 27 kg/m2 compared with South Asian patients (37% vs 21%, p < 0.001), South Asian patients had a higher waist circumference than WB (94.8 cm vs 90.8 cm, p < 0.001). Adjusting for traditional stroke risk factors, ISA, BSA, and QSA continued to display an increased risk of diabetes compared with WB by 3.28 (95% CI: 2.53-4.25, p < 0.001), 3.61 (95% CI: 2.90-4.51, p < 0.001), and 5.24 (95% CI: 3.93-7.00, p < 0.001), respectively. CONCLUSION: South Asian ischemic stroke patients living in Britain and Qatar have a near 3.5-fold risk of diabetes compared with White British stroke patients. Their body composition may partly help explain that increased risk. These findings have important implications for public health policymakers in nations with large South Asian populations.

Determination of independent risk factors for early healthcare-associated infections acquired after acute stroke admission: A multi-centre registry-based cohort study.

OBJECTIVE: Healthcare-associated infections (HCAIs) in patients admitted with acute conditions pose a serious risk to patients and a major challenge to healthcare services. However, there is a lack of consistency in reporting aetiological risk factors, particularly in acute stroke patients. Here, we determined independent risk factors of two common HCAIs (urinary tract infection and pneumonia) acquired within 7-days of admission after an acute stroke. METHODS: Data were prospectively collected (2014-2016) from the Sentinel Stroke National Audit Programme for 3,309 patients (mean age=76.2yr, SD=13.5) admitted to four UK hyperacute stroke units. Associations between variables were assessed by forward stepwise multivariable logistic regression (odds ratios, 95 % confidence intervals). RESULTS: The rate of urinary tract infection and/or pneumonia occurring within 7-days of admission was 15.0 %. The risk of urinary tract infection and/or pneumonia was increased amongst women: OR = 1.35 (1.08-1.68); patients from ethnic minority backgrounds: OR = 1.77 (1.01-3.10); patients aged 70-79 years: OR = 2.08 (1.42-3.06), and ≥80 years: OR = 3.20 (2.26-4.55); history of hypertension: OR = 1.59 (1.27-1.98); history of atrial fibrillation: OR = 1.67 (1.32-2.12); pre-stroke disability: OR = 2.08 (1.44-3.00); intracranial haemorrhage: OR = 1.41 (1.07-1.86); severe stroke: OR = 3.21 (2.32-4.45); swallow screening within 4-72 h: OR = 1.42 (1.08-1.86); swallow screening beyond 72 h: OR = 1.70 (1.08-2.70). History of congestive heart failure, diabetes and previous stroke did not significantly associate with HCAIs. CONCLUSIONS: A profile of independent risk factors for two common HCAIs in acute stroke was identified. These findings provide valuable information for timely intervention to reduce HCAIs, and the ability to minimise subsequent adverse outcomes.

Influences of the COVID-19 pandemic on admissions and clinical outcomes in mental health disorders and self-poisoning: Age- and sex-specific analysis.

We measured rates of hospital admissions for mental health disorders and self-poisoning during the pandemic in patients without COVID-19, compared to those admitted before the pandemic. Data were collected from 01/04/2019 to 31/03/2021, including the pandemic period from 01/03/2020. There were 10 173 (47.7% men) from the pre-pandemic and 11 019 (47.5% men) from the pandemic periods; mean age = 68.3 year. During the pandemic, admission rates for mental health disorders and self-poisoning were higher for any given age and sex. Self-poisoning was increased with toxic substances, sedatives and psychotropic drugs, but reduced with nonopioid analgesics. Patients admitted with mental health disorders had lower readmission rates within 28 days during the pandemic, but did not differ in other outcomes. Outcomes from self-poisoning did not change between the two study periods.

Age of onset of cerebral venous thrombosis: the BEAST study.

Background: Cerebral venous thrombosis (CVT) is an uncommon cause of stroke in young adults. We aimed to determine the impact of age, gender and risk factors (including sex-specific) on CVT onset. Methods: We used data from the BEAST (Biorepository to Establish the Aetiology of Sinovenous Thrombosis), a multicentre multinational prospective observational study on CVT. Composite factors analysis (CFA) was performed to determine the impact on the age of CVT onset in males and females. Results: A total of 1309 CVT patients (75.3% females) aged ⩾18 years were recruited. The overall median (IQR-interquartile range) age for males and females was 46 (35-58) years and 37 (28-47) years (p < 0.001), respectively. However, the presence of antibiotic-requiring sepsis (p = 0.03, 95% CI 27-47 years) among males and gender-specific risk factors like pregnancy (p < 0.001, 95% CI 29-34 years), puerperium (p < 0.001, 95% CI 26-34 years) and oral contraceptive use (p < 0.001, 95% CI 33-36 years) were significantly associated with earlier onset of CVT among females. CFA demonstrated a significantly earlier onset of CVT in females, ~12 years younger, in those with multiple (⩾1) compared to '0' risk factors (p < 0.001, 95% CI 32-35 years). Conclusions: Women suffer CVT 9 years earlier in comparison to men. Female patients with multiple (⩾1) risk factors suffer CVT ~12 years earlier compared to those with no identifiable risk factors.

Adverse stroke outcomes amongst UK ethnic minorities: a multi-centre registry-based cohort study of acute stroke.

OBJECTIVE: Socioeconomic and health inequalities persist in multicultural western countries. Here, we compared outcomes following an acute stroke amongst ethnic minorities with Caucasian patients. METHODS: Data were prospectively collected (2014-2016) from the Sentinel Stroke National Audit Programme for 3309 patients who were admitted with an acute stroke in four UK hyperacute stroke units. Associations between variables were examined by chi-squared tests and multivariable logistic regression, adjusted for age, sex, prestroke functional limitations and co-morbidities, presented as odds ratios (OR) with 95% CI. RESULTS: There were 3046 Caucasian patients, 95 from ethnic minorities (mostly South Asians, Blacks, mixed race and a few in other ethnic groups) and 168 not stated. Compared with Caucasian patients, those from ethnic minorities had a proportionately higher history of diabetes (33.7% vs 15.4%, P < 0.001), but did not differ in other chronic conditions, functional limitations or sex distribution. Their age of stroke onset was younger both in women (76.8 year vs 83.2 year, P < 0.001) and in men (69.5 year vs 75.9 year, P = 0.002). They had greater risk for having a stroke before the median age of 79.5 year: OR = 2.15 (1.36-3.40) or in the first age quartile (< 69 year): OR = 2.91 (1.86-4.54), requiring palliative care within the first 72 h: OR = 3.88 (1.92-7.83), nosocomial pneumonia or urinary tract infection within the first 7 days of admission: OR = 1.86 (1.06-3.28), and in-hospital mortality: OR = 2.50 (1.41-4.44). CONCLUSIONS: Compared with Caucasian patients, those from ethnic minorities had earlier onset of an acute stroke by about 5 years and a 2- to fourfold increase in many stroke-related adverse outcomes and death.

Reduction of adverse outcomes from cesarean section by surgical-site infection prevention care bundles in maternity.

OBJECTIVE: To reduce average surgical-site infection (SSI) rates to less than 7.5%, as well as other complications by incrementally implementing an SSI prevention care bundle in maternity: (1) ChloraPrep; (2) PICO dressings, performing elective cesarean sections in a main theater rather than a labor ward and warming blankets; (3) vaginal cleansing; and (4) Hibiscrub. METHODS: In this prospective cohort study, the association between categorical variables was assessed by χ2 tests, temporal trends in the monthly percentage change of SSI were measured using the Joinpoint Regression Program v4.7.0.0. RESULTS: In all, 1682 women (mean age 33.1 ± 5.2 years) underwent either elective (53.9%) or emergency (46.1%) cesarean section. After a small initial increase (10.0%-11.8%), SSI progressively declined to 4.4% (χ2  = 22.1, P < 0.001), as did sepsis, reoperation or readmission for SSI: from 12.5% to 0.5% (χ2  = 90.1, P < 0.001). The rates of SSI fell progressively with the cumulative introduction care bundle components. The average monthly percentage change was -14.0% (95% confidence interval -21.8% to -5.4%, P = 0.004), and the average SSI rate was kept below 7.5% for the last 12 months of the study. CONCLUSION: The maternal SSI prevention care bundle is simple and inexpensive; it effectively reduces SSI after a cesarean section and should be offered routinely to women undergoing cesarean section.

Evaluation of independent risk factors associated with surgical site infections from caesarean section.

BACKGROUND: The present study assessed factors associated with the risk of surgical site infections (SSI) after a caesarean section (C-section). METHODS: Data were collected in 1682 women undergoing elective (53.9%) and emergency (46.1%) C-sections between 1st August 2020, and 30th December 2021, at a National Health Service hospital (Surrey, UK). RESULTS: At the time of C-section, the mean age was 33.1 yr (SD ± 5.2). Compared to women with BMI < 30 kg/m2, those with a BMI ≥ 35 kg/m2 had a greater risk of SSI, OR 4.07 (95%CI 2.48-6.69). Women with a history of smoking had a greater risk of SSI than those who had never smoked, OR 1.69 (95%CI 1.05-2.27). Women with a BMI ≥ 30 kg/m2 and had a smoking history or emergency C-section had 3- to tenfold increases for these adverse outcomes. Ethnic minority, diabetes or previous C-section did not associate with any of the outcomes. CONCLUSIONS: High BMI, smoking, and emergency C-section are independent risk factors for SSI from C-section. Women planning conception should avoid excess body weight and smoking. Women with diabetes and from ethnic minority backgrounds did not have increased risks of SSI, indicating a consistent standard of care for all patients.

Identification of preoperative factors and postoperative outcomes in relation to delays in surgery for hip fractures.

We evaluated factors and outcomes associated with elapsed time to surgery (ETTS) in 1,081 men and 2,891 women (mean age 83.5 years ±9.1) undergoing hip fracture surgery (from 2009-2019). Mortality rates were 4.8%, 6.3%, 6.2% and 10.3% (chi-squared 19.0; p<0.001), and hospital length of stay (LOS) >19 days were 31.9%, 32.8%, 33.8% and 43.2% (chi-squared 18.5; p<0.001) for ETTS <24 hours, 24-35 hours, 36-47 hours and ≥48 hours, respectively. There were no differences between ETTS categories for failure to mobilise within 1 day of surgery, pressure ulcers or discharge to nursing care. After adjustment for age, sex, American Society of Anesthesiologists' score and years of data collection, compared with Sunday, the risk of ETTS ≥36 hours was highest on Friday (odds ratio (OR) 3.50; 95% confidence interval (CI) 2.43-5.03) and Saturday (OR 4.70; 95% CI 3.26-6.76). Compared with ETTS <24 hours, there were increases in the risk of death when ETTS ≥48 hours (OR 2.31; 95% CI 1.47-3.65) and LOS >19 days (OR 1.34; 95% CI 1.02-1.75). The median (interquartile range (IQR)) LOS for ETTS <24 hours was 12.7 days (IQR 8.0-23.0), 24-35 hours was 13.5 days (IQR 8.4-22.9), 36-47 hours was 14.1 days (IQR 8.9-23.3) and ≥48 hours was 16.9 (IQR 10.8-27.0; p<0.001). The 10-year period of collection did not change the conclusion. Admissions towards the end of the week are associated with delayed ETTS for hip fractures, while delay in surgery, particularly beyond 48 hours, is associated with increased risk of mortality and prolonged LOS.

Reproductive hormone levels, androgen receptor CAG repeat length and their longitudinal relationships with decline in cognitive subdomains in men: The European Male Ageing Study.

OBJECTIVE: It has been proposed that endogenous sex hormone levels may present a modifiable risk factor for cognitive decline. However, the evidence for effects of sex steroids on cognitive ageing is conflicting. We therefore investigated associations between endogenous hormone levels, androgen receptor CAG repeat length, and cognitive domains including visuoconstructional abilities, visual memory, and processing speed in a large-scale longitudinal study of middle-aged and older men. METHODS: Men aged 40-79 years from the European Male Ageing Study (EMAS) underwent cognitive assessments and measurements of hormone levels at baseline and follow-up (mean = 4.4 years, SD ± 0.3 years). Hormone levels measured included total and calculated free testosterone and estradiol, dihydrotestosterone, luteinizing hormone, follicle-stimulating hormone, dehydroepiandrosterone sulphate and sex hormone-binding globulin. Cognitive function was assessed using the Rey-Osterrieth Complex Figure Copy and Recall, the Camden Topographical Recognition Memory and the Digit Symbol Substitution Test. Multivariate linear regressions were used to examine associations between baseline and change hormone levels, androgen receptor CAG repeat length, and cognitive decline. RESULTS: Statistical analyses included 1,827 and 1,423 participants for models investigating relationships of cognition with hormone levels and CAG repeat length, respectively. In age-adjusted models, we found a significant association of higher baseline free testosterone (ß=-0.001, p=0.005) and dihydrotestosterone levels (ß=-0.065, p=0.003) with greater decline on Rey-Osterrieth Complex Figure Recall over time. However, these effects were no longer significant following adjustment for centre, health, and lifestyle factors. No relationships were observed between any other baseline hormone levels, change in hormone levels, or androgen receptor CAG repeat length with cognitive decline in the measured domains. CONCLUSIONS: In this large-scale prospective study there was no evidence for an association between endogenous sex hormone levels or CAG repeat length and cognitive ageing in men. These data suggest that sex steroid levels do not affect visuospatial function, visual memory, or processing speed in middle-aged and older men.

Comparison of characteristics, management and outcomes in hospital-onset and community-onset stroke: a multi-centre registry-based cohort study of acute stroke.

OBJECTIVE: Hospital-onset stroke (HOS) is associated with poorer outcomes than community-onset stroke (COS). Previous studies have variably documented patient characteristics and outcome measures; here, we compare in detail characteristics, management and outcomes of HOS and COS. METHODS: A total of 1656 men (mean age ± SD = 73.1 years ± 13.2) and 1653 women (79.3 years ± 13.0), with data prospectively collected (2014-2016) from the Sentinel Stroke National Audit Programme, were admitted with acute stroke in four UK hyperacute stroke units (HASU). Associations between variables were examined by chi-squared tests and multivariable logistic regression (COS as reference). RESULTS: There were 272 HOS and 3037 COS patients with mean ages of 80.2 years ± 12.5 and 76.4 years ± SD13.5 and equal sex distribution. Compared to COS, HOS had higher proportions ≥ 80 years (64.0% vs 46.4%), congestive heart failure (16.9% vs 4.9%), atrial fibrillation (25.0% vs 19.7%) and pre-stroke disability (9.6% vs 5.1%), and similar history of stroke, hypertension, diabetes, stroke type and severity of stroke. After age, sex and co-morbidities adjustments, HOS had greater risk of pneumonia: OR (95%CI) = 1.9 (1.3-2.6); malnutrition: OR = 2.2 (1.7-2.9); immediate thrombolysis complications: OR = 5.3 (1.5-18.2); length of stay on HASU > 3 weeks: OR = 2.5 (1.8-3.4); post-stroke disability: OR = 1.8 (1.4-2.4); and in-hospital mortality: OR = 1.8 (1.2-2.4), as well as greater support at discharge including palliative care: OR = 1.9 (1.3-2.8); nursing care: OR = 2.0 (1.3-4.0), help for daily living activities: OR = 1.6 (1.1-2.2); and joint-care planning: OR = 1.5 (1.1-1.9). CONCLUSIONS: This detailed analysis of underlying differences in subject characteristics between patients with HOS or COS and adverse consequences provides further insights into understanding poorer outcomes associated with HOS.

Predicting Stroke Complications in Hospital and Functional Status at Discharge by Clustering of Cardiovascular Diseases a Multi-Centre Registry-Based Study of Acute Stroke.

OBJECTIVE: Indicators for outcomes following acute stroke are lacking. We have developed novel evidence-based criteria for identifying outcomes of acute stroke using the presence of clusters of coexisting cardiovascular disease (CVD). MATERIALS AND METHODS: Analysis of prospectively collected data from the Sentinel Stroke National Audit Programme (SSNAP). A total of 1656 men (mean age ±SD=73.1yrs±13.2) and 1653 women (79.3yrs±13.0) were admitted with acute stroke (83.3% ischaemic, 15.7% intracranial haemorrhagic), 1.0% unspecified) in four major UK hyperacute stroke units (HASU) between 2014 and 2016. Four categories from cardiovascular disease Congestive heart failure, Atrial fibrillation, pre-existing Stroke and Hypertension (CASH).were constructed: CASH-0 (no coexisting CVD); CASH-1 (any one coexisting CVD); CASH-2 (any two coexisting CVD); CASH-3 (any three or all four coexisting CVD). These were tested against outcomes, adjusted for age and sex. RESULTS: Compared to CASH-0, individuals with CASH-3 had greatest risks of in-hospital mortality (11.1% vs 24.5%, OR=1.8, 95%CI=1.3-2.7) and disability (modified Rankin Scale score ≥4) at discharge (24.2% vs 46.2%, OR=1.9, 95%CI=1.4-2.7), urinary tract infection (3.8% vs 14.6%, OR= 3.3, 95%CI= 1.9-5.5), and pneumonia (7.1% vs 20.6%, OR= 2.6, 95%CI= 1.7-4.0); length of stay on HASU >14 days (29.8% vs 39.3%, OR=1.8, 95%CI=1.3-2.6); and joint-care planning (20.9% vs 29.8%, OR=1.4, 95%CI=1.0-2.0). CONCLUSIONS: We present a simple tool for estimating the risk of adverse outcomes of acute stroke including death, disability at discharge, nosocomial infections, prolonged length of stay, as well as any joint care planning. CASH-0 indicates a low level and CASH-3 indicates a high level of risk of such complications after stroke.

Association of risk of malnutrition with adverse outcomes and early support on discharge in acute stroke patients without prestroke disability: A multicenter, registry-based cohort study.

BACKGROUND: Malnutrition in hospitals remains highly prevalent. As part of quality improvement initiatives, the Royal College of Physicians recommends nutrition screening for all patients admitted with acute stroke. We aimed to examine the associations of patients at risk of malnutrition with poststroke outcomes. METHODS: We analyzed prospectively collected data from four hyperacute stroke units (HASUs) (2014-2016). Nutrition status was screened in 2962 acute stroke patients without prestroke disability (1515 men, [mean ± SD] 73.5 years ± 13.1; 1447 women, 79.2 ± 13.0 years). The risk of malnutrition was tested against stroke outcomes and adjusted for age, sex, and comorbidities. RESULTS: Risk of malnutrition was identified in 25.8% of patients). Compared with well-nourished patients, those at risk of malnutrition had, within 7 days of admission, increased risk of stay on the HASU of >14 days (odds ratio [OR]: 9.9 [7.3-11.5]), disability on discharge (OR: 8.1 [6.6-10.0]), worst level of consciousness in the first 7 days (score ≥ 1) (OR: 7.5 [6.1-9.3]), mortality (OR: 5.2 [4.0-6.6], pneumonia (OR: 5.1 [3.9-6.7]), and urinary tract infection (OR: 1.5 [1.1-2.0]). They also required palliative care (OR: 12.3 [8.5-17.8]), discharge to new care home (OR: 3.07 [2.18-4.3]), activities of daily living support (OR: 1.8 [1.5-2.3]), planned joint care (OR: 1.5 [1.2-1.8]), and weekly visits (OR: 1.4 [1.1-1.8]). CONCLUSION: Patients at risk of malnutrition more commonly have multiple adverse outcomes after acute stroke and greater need for early support on discharge.

Changes in Characteristics and Outcomes of Patients Undergoing Surgery for Hip Fractures Following the Initiation of Orthogeriatric Service: Temporal Trend Analysis.

The Blue Book published by the British Orthopaedic Association and British Geriatrics Society, together with the introduction of National Hip Fracture Database Audit and Best Practice Tariff, have been influential in improving hip fracture care. We examined ten-year (2009-2019) changes in hip fracture outcomes after establishing an orthogeriatric service based on these initiatives, in 1081 men and 2891 women (mean age = 83.5 ± 9.1 years). Temporal trends in the annual percentage change (APC) of outcomes were identified using the Joinpoint Regression Program v4.7.0.0. The proportions of patients operated beyond 36 h of admission fell sharply during the first two years: APC = - 53.7% (95% CI - 68.3, - 5.2, P = 0.003), followed by a small rise thereafter: APC = 5.8% (95% CI 0.5, 11.3, P = 0.036). Hip surgery increased progressively in patients > 90 years old: APC = 3.3 (95% CI 1.0, 5.8, P = 0.011) and those with American Society of Anaesthesiologists grade ≥ 3: APC = 12.4 (95% CI 8.8, 16.1, P < 0.001). There was a significant decline in pressure ulcers amongst patients < 90 years old: APC = - 17.9 (95% CI - 32.7, 0.0, P = 0.050) and also a significant decline in mortality amongst those > 90 years old: APC = - 7.1 (95% CI - 12.6, - 1.3, P = 0.024). Prolonged length of stay (> 23 days) declined from 2013: APC = - 24.6% (95% CI - 31.2, - 17.4, P < 0.001). New discharge to nursing care declined moderately over 2009-2016 (APC = - 10.6, 95% CI - 17.2, - 2.7, P = 0.017) and sharply thereafter (APC = - 47.5%, 95%CI - 71.7, - 2.7, P = 0.043). The rate of patients returning home was decreasing (APC = - 2.9, 95% CI - 5.1, - 0.7, P = 0.016), whilst new discharge to rehabilitation was increasing (APC = 8.4, 95% CI 4.0, 13.0; P = 0.002). In conclusion, the establishment of an orthogeriatric service was associated with a reduction of elapsed time to hip surgery, a progressive increase in surgery carried out on high-risk adults and a decline in adverse outcomes.

Adverse consequences of immediate thrombolysis-related complications: a multi-centre registry-based cohort study of acute stroke.

Complications following thrombolysis for stroke are well documented, and mostly concentrated on haemorrhage. However, the consequences of patients who experience any immediate thrombolysis-related complications (TRC) compared to patients without immediate TRC have not been examined. Prospectively collected data from the Sentinel Stroke National Audit Programme were analysed. Thrombolysis was performed in 451 patients (52.1% men; 75.3 years ± 13.2) admitted with acute ischaemic stroke (AIS) in four UK centres between 2014 and 2016. Adverse consequences following immediate TRC were assessed using logistic regression, adjusted for age, sex and co-morbidities. Twenty-nine patients (6.4%) acquired immediate TRC. Compared to patients without, individuals with immediate TRC had greater adjusted risks of: moderately-severe or severe stroke (National Institutes of Health for Stroke Scale score ≥ 16) at 24-h (5.7% vs 24.7%, OR 3.9, 95% CI 1.4-11.1); worst level of consciousness (LOC) in the first 7 days (score ≥ 1; 25.0 vs 60.7, OR 4.6, 95% CI 2.1-10.2); urinary tract infection or pneumonia within 7-days of admission (13.5% vs 39.3%, OR 3.2, 95% CI 1.3-7.7); length of stay (LOS) on hyperacute stroke unit (HASU) ≥ 2 weeks (34.7% vs 66.7%, OR 5.2, 95% CI 1.5-18.4); mortality (13.0% vs 41.4%, OR 3.7, 95% CI 1.6-8.4); moderately-severe or severe disability (modified Rankin Scale score ≥ 4) at discharge (26.8% vs 65.5%, OR 4.7, 95% CI 2.1-10.9); palliative care by discharge date (5.1% vs 24.1%, OR 5.1, 95% CI 1.7-15.7). The median LOS on the HASU was longer (7 days vs 30 days, Kruskal-Wallis test: χ2 = 8.9, p = 0.003) while stroke severity did not improve (NIHSS score at 24-h post-thrombolysis minus NIHSS score at arrival = - 4 vs 0, χ2 = 24.3, p < 0.001). In conclusion, the risk of nosocomial infections, worsening of stroke severity, longer HASU stay, disability and death is increased following immediate TRC. The management of patients following immediate TRC is more complex than previously thought and such complexity needs to be considered when planning an increased thrombolysis service.

Evaluation of the association of length of stay in hospital and outcomes.

BACKGROUND: There exist wide variations in healthcare quality within the National Health Service (NHS). A shorter hospital length of stay (LOS) has been implicated as premature discharge, that may in turn lead to adverse consequences. We tested the hypothesis that a short LOS might be associated with increased risk of readmissions within 28 days of hospital discharge and also post-discharge mortality. METHODS: We conducted a single-centred study of 32 270 (46.1% men) consecutive alive-discharge episodes (mean age = 64.0 years, standard deviation = 20.5, range = 18-107 years), collected between 01/04/2017 and 31/03/2019. Associations of LOS tertiles (middle tertile as a reference) with readmissions and mortality were assessed using observed/expected ratios, and logistic and Cox regressions to estimate odds (OR) and hazard ratios (HR) (adjusted for age, sex, patients' severity of underlying health status and index admissions), with 95% confidence intervals (CIs). RESULTS: The observed numbers of readmissions within 28 days of hospital discharge or post-discharge mortality were lower than expected (observed: expected ratio < 1) in patients in the bottom tertile (<1.2 days) and middle tertile (1.2-4.3 days) of LOS, whilst higher than expected (observed: expected ratio > 1) in patients in the top tertile (>4.3 days), amongst all ages. Patients in the top tertile of LOS had increased risks for one readmission: OR = 2.32 (95% CI = 1.86-2.88) or ≥2 readmissions: OR = 6.17 (95% CI = 5.11-7.45), death within 30 days: OR = 2.87 (95% CI = 2.34-3.51), and within six months of discharge: OR = 2.52 (95% CI = 2.23-2.85), and death over a two-year period: HR = 2.25 (95% CI = 2.05-2.47). The LOS explained 7.4% and 15.9% of the total variance (r2) in one readmission and ≥2 readmissions, and 9.1% and 10.0% of the total variance in mortality with 30 days and within six months of hospital discharge, respectively. Within the bottom, middle and top tertiles of the initial LOS, the median duration from hospital discharge to death progressively shortened from 136, 126 to 80 days, whilst LOS during readmission lengthened from 0.4, 0.9 to 2.8 days, respectively. CONCLUSION: Short LOS in hospital was associated with favourable post-discharge outcomes such as early readmission and mortality, and with a delay in time interval from discharge to death and shorter LOS in hospital during readmission. These findings indicate that timely discharge from our hospital meets the aims of the NHS-generated national improvement programme, Getting It Right First Time.
