Prognostic impact of CONUT score in older patients with chronic heart failure.

BACKGROUND: Malnutrition is common in older patients with chronic heart failure (HF) and often accompanies a deterioration of their condition. The Controlling Nutritional Status (CONUT) score is used as an objective indicator to evaluate nutritional status, but relevant research in this area is limited. This study aimed to report the prevalence, clinical correlates, and outcomes of malnutrition in elder patients hospitalized with chronic HF. METHODS: A retrospective analysis was conducted on 165 eligible patients admitted to the Department of Cardiology at Huadong Hospital from January 2021 to December 2022. Patients were categorized based on their CONUT score into three groups: normal nutrition status, mild risk of malnutrition, and moderate to severe risk of malnutrition. The study examined the nutritional status of this population and its relationship with clinical outcomes. RESULTS: Findings revealed that malnutrition affected 82% of the older patients, with 28% experiencing moderate to severe risk. Poor nutritional scores were significantly associated with prolonged hospital stay, increased in-hospital mortality and all-cause mortality during readmissions within one year (P < 0.05). The multivariable analysis indicated that moderate to severe malnutrition (CONUT score of 5-12) was significantly associated with a heightened risk of prolonged hospitalization (aOR: 9.17, 95%CI: 2.02-41.7). CONCLUSIONS: Malnutrition, as determined by the CONUT score, is a common issue among HF patients. Utilizing the CONUT score upon admission can effectively predict the potential for prolonged hospital stays.

Has multimorbidity and frailty in adult hospital admissions changed over the last 15 years? A retrospective study of 107 million admissions in England.

BACKGROUND: Few studies have quantified multimorbidity and frailty trends within hospital settings, with even fewer reporting how much is attributable to the ageing population and individual patient factors. Studies to date have tended to focus on people over 65, rarely capturing older people or stratifying findings by planned and unplanned activity. As the UK's national health service (NHS) backlog worsens, and debates about productivity dominate, it is essential to understand these hospital trends so health services can meet them. METHODS: Hospital Episode Statistics inpatient admission records were extracted for adults between 2006 and 2021. Multimorbidity and frailty was measured using Elixhauser Comorbidity Index and Soong Frailty Scores. Yearly proportions of people with Elixhauser conditions (0, 1, 2, 3 +) or frailty syndromes (0, 1, 2 +) were reported, and the prevalence between 2006 and 2021 compared. Logistic regression models measured how much patient factors impacted the likelihood of having three or more Elixhauser conditions or two or more frailty syndromes. Results were stratified by age groups (18-44, 45-64 and 65 +) and admission type (emergency or elective). RESULTS: The study included 107 million adult inpatient hospital episodes. Overall, the proportion of admissions with one or more Elixhauser conditions rose for acute and elective admissions, with the trend becoming more prominent as age increased. This was most striking among acute admissions for people aged 65 and over, who saw a 35.2% absolute increase in the proportion of admissions who had three or more Elixhauser conditions. This means there were 915,221 extra hospital episodes in the last 12 months of the study, by people who had at least three Elixhauser conditions compared with 15 years ago. The findings were similar for people who had one or more frailty syndromes. Overall, year, age and socioeconomic deprivation were found to be strongly and positively associated with having three or more Elixhauser conditions or two or more frailty syndromes, with socioeconomic deprivation showing a strong dose-response relationship. CONCLUSIONS: Overall, the proportion of hospital admissions with multiple conditions or frailty syndromes has risen over the last 15 years. This matches smaller-scale and anecdotal reports from hospitals and can inform how hospitals are reimbursed.

Association between polypharmacy and 2-year outcomes among Chinese older inpatients: a multi-center cohort study.

BACKGROUND: The escalating global prevalence of polypharmacy presents a growing challenge to public health. In light of this issue, the primary objective of our study was to investigate the status of polypharmacy and its association with clinical outcomes in a large sample of hospitalized older patients aged 65 years and over. METHODS: A two-year prospective cohort study was carried out at six tertiary-level hospitals in China. Polypharmacy was defined as the prescription of 5 or more different medications daily, including over-the-counter and non-prescription medications. Baseline polypharmacy, multimorbidity, and other variables were collected when at admission, and 2-year outcomes were recorded by telephone follow-up. We used multivariate logistic regression analysis to examine the associations between polypharmacy and 2-year outcomes. RESULTS: The overall response rate was 87.2% and 8713 participants were included in the final analysis. The mean age was 72.40 years (SD = 5.72), and women accounted for 42.2%. The prevalence of polypharmacy among older Chinese inpatients is 23.6%. After adjusting for age, sex, education, marriage status, body mass index, baseline frailty, handgrip strength, cognitive impairment, and the Charlson comorbidity index, polypharmacy is significantly associated with frailty aggravation (OR 1.432, 95% CI 1.258-1.631) and mortality (OR 1.365, 95% CI 1.174-1.592), while inversely associated with readmission (OR 0.870, 95% CI 0.764-0.989). Polypharmacy was associated with a 35.6% increase in the risk of falls (1.356, 95%CI 1.064-1.716). This association weakened after adjustment for multimorbidity to 27.3% (OR 1.273, 95%CI 0.992-1.622). CONCLUSIONS: Polypharmacy was prevalent among older inpatients and was a risk factor for 2-year frailty aggravation and mortality. These results highlight the importance of optimizing medication use in older adults to minimize the risks associated with polypharmacy. Further research and implementing strategies are warranted to enhance the quality of care and safety for older individuals exposed to polypharmacy.

Mortality and functional outcomes 18 months after hospitalization for COVID-19 in geriatric patients: a multicentric cohort study.

BACKGROUND: Few data are available on the long-term mortality and functional status of geriatric patients surviving after hospitalization for COVID-19. We compared the mortality and functional status 18 months after hospitalization for geriatric patients who were hospitalized for COVID-19 or another diagnosis. METHODS: This was a multicentric cohort study in Paris from January to June 2021. We included patients aged 75 years and over who were hospitalized with COVID-19 or not during this period and compared their vital and functional status 18 months after hospitalization. RESULTS: We included 254 patients (63 hospitalized for COVID-19). As compared with patients hospitalized for other reasons, those hospitalized for COVID-19 were younger (mean [SD] age 86 [6.47] vs. 88 [6.41] years, p = 0.03), less frail (median Clinical Frailty Scale score 5 [4-6] vs. 6 [4-6], p 0.007) and more independent at baseline (median activities of daily living score 5.5 [4-6] vs. 5 [3.5-6], p 0.03; instrumental activities of daily living score 3 [1-4] vs. 2 [0-3], p 0.04). At 18 months, 50.8% (n = 32/63) of COVID-19 patients had died versus 66% (n = 126/191) of non-COVID-19 patients (p 0.03). On multivariate analysis, COVID-19 positivity was not significantly associated with 18-month mortality (adjusted hazard ratio 0.67, 95% confidence interval 0.40 to 1.13). At 18 months, the two groups did not differ in activities of daily living or frailty scores. CONCLUSIONS: In this multicenter study of long-term mortality in geriatric patients discharged alive after hospitalization, positive COVID-19 status was not associated with excess mortality.

Trends in US Pediatric Asthma Hospitalizations, by Race and Ethnicity, 2012-2020.

Introduction: Some racial and ethnic minority communities have long faced a higher asthma burden than non-Hispanic White communities. Prior research on racial and ethnic pediatric asthma disparities found stable or increasing disparities, but more recent data allow for updated analysis of these trends. Methods: Using 2012-2020 National Inpatient Sample data, we estimated the number of pediatric asthma hospitalizations by sex, age, and race and ethnicity. We converted these estimates into rates using data from the US Census Bureau and then conducted meta-regression to assess changes over time. Because the analysis spanned a 2015 change in diagnostic coding, we performed separate analyses for periods before and after the change. We also excluded 2020 data from the regression analysis. Results: The number of pediatric asthma hospitalizations decreased over the analysis period. Non-Hispanic Black children had the highest prevalence (range, 9.8-36.7 hospitalizations per 10,000 children), whereas prevalence was lowest among non-Hispanic White children (range, 2.2-9.4 hospitalizations per 10,000 children). Although some evidence suggests that race-specific trends varied modestly across groups, results overall were consistent with a similar rate of decrease across all groups (2012-2015, slope = -0.83 [95% CI, -1.14 to -0.52]; 2016-2019, slope = -0.35 [95% CI, -0.58 to -0.12]). Conclusion: Non-Hispanic Black children remain disproportionately burdened by asthma-related hospitalizations. Although the prevalence of asthma hospitalization is decreasing among all racial and ethnic groups, the rates of decline are similar across groups. Therefore, previously identified disparities persist. Interventions that consider the specific needs of members of disproportionately affected groups may reduce these disparities.

Trends in Hospitalisations for Vaccine Preventable Respiratory Infections Following Emergency Department Presentations in New South Wales, Australia, 2012-2022.

BACKGROUND: Vaccine-preventable respiratory infections impact on healthcare systems globally. Despite availability of vaccines, fluctuations in vaccination rates, pathogen virulence and community transmission dynamics mean that these respiratory infections continue to pose substantial public health risks. To understand trends in vaccine-preventable respiratory infections, we analysed linked data from emergency department (ED), hospitalisations and deaths in New South Wales, Australia, from 2012 to 2022. METHODS: ED presentations with respiratory infection like illness were linked to hospitalisation and death records. Age-standardised rates of ED presentations, proportions subsequently hospitalised for acute respiratory infection (ARI) and specific vaccine-preventable disease diagnoses and 28-day mortality rates were estimated by year and age. RESULTS: From 2012 to 2022, there were 3,127,090 ARI-like ED presentations. Age-standardised rates increased until 2020, declined in 2021 and rebounded in 2022. Across all years, of these ARI-like ED presentations, 16.6% were hospitalised for acute respiratory infections, including pneumonia (7.9%), influenza (1.1%), RSV disease (1.3%), COVID-19 (0.8%) and pneumococcal disease (0.3%). Proportions hospitalised were highest in those aged 65+ years, except for RSV, which was highest in children aged 0-4 years. The highest 28-day mortality post-ARI-like ED presentation was observed with COVID-19 in adults aged 65+ years at 13.1%. CONCLUSIONS: This study highlights the continuing burden of vaccine-preventable respiratory infections on an Australian healthcare system. These data can be used to monitor the effectiveness of vaccination programmes and other public health interventions. Future efforts should focus on enhancing surveillance and data linkage to improve precision and guide targeted public health strategies.

Temporal Trend in Hospitalization Among Patients With Congenital Heart Disease: A Danish Nationwide Study.

BACKGROUND: The congenital heart disease (CHD) population is growing and aging. We aim to examine the impact by describing the temporal trend and causes of lifetime hospitalization burden among the CHD population. METHODS AND RESULTS: From the Danish National Patient Registry, 23 141 patients with CHD and their hospitalizations from 1977 to 2018 were identified, excluding patients with extracardiac malformation. Patients with CHD were categorized into major CHD and minor CHD, and each patient was matched with 10 controls by sex and year of birth. The rate of all-cause hospitalization increased over time from 28.3 to 36.4 hospitalizations per 100 person-years (PY) with rate difference (RD) per decade of 2.5 (95% CI, 2.0-3.1) hospitalizations per 100 PY for the patients with CHD, compared with the increase from 10.8 to 17.0 per 100 PY (RD per decade, 2.0 [95% CI, 1.8-2.2] per 100 PY) for the control group (RD for CHD versus control, P=0.08). The all-cause hospitalization rate remained constant for the major CHDs (RD per decade, -0.2 [95% CI, -1.2 to 0.9] per 100 PY) but increased for the minor CHDs (RD per decade, 5.2 [95% CI, 4.3-6.0] per 100 PY). For all patients with CHD, the cardiovascular hospitalization rate remained constant over time (RD per decade, 0.2 [95% CI, -0.3 to 0.6] per 100 PY) whereas the noncardiovascular hospitalization rate increased (RD per decade, 2.1 [95% CI, 1.6-2.7] per 100 PY). The length of all-cause hospital stays for all patients with CHD decreased from 2.7 (95% CI, 2.6-2.8) days per PY in 1977 to 1987 to 1.6 (95% CI, 1.6-1.7) days per PY in 2008 to 2018. CONCLUSIONS: Compared with previous decades, patients with CHD have an increasing hospitalization rate, similar to the general population, but a decreasing length of hospital stay. The increase in hospitalization rate was driven by noncardiovascular hospitalizations, with the patients with minor CHD being the key contributor to the increasing rate.

Racial disparities in trend, clinical characteristics and outcomes in Takotsubo syndrome.

INTRODUCTION: Takotsubo syndrome (TTS) is an acute transient nonischemic cardiomyopathy often characterized by its hallmark feature of left ventricular apical ballooning. The correlation between racial backgrounds and the prognosis of individuals with TTS remains poorly defined. Our study aimed to explore the influence of race on the trends, clinical presentations, and outcomes in patients diagnosed with TTS. METHODS: We queried the National Inpatient Sample (NIS) database from 2016 to 2020 and identified hospitalizations with TTS. We compared the clinical features and outcomes across three different races - non-Hispanic White (NHW), non-Hispanic Black (NHB), and Hispanic population. The primary outcome was in-hospital mortality. RESULTS: 76,505 weighted hospitalizations for TTS were identified, of which 65,495 (85.6%) were non-Hispanic White, 5,830 (7.6%) were non-Hispanic Black, and 5,180 (6.8%) were Hispanics. After propensity-score matching, NHB patients had higher odds of acute kidney injury (OR: 1.49, 95% CI: 1.21-1.84, p < 0.001) and mechanical ventilation (OR: 1.33, 95% CI: 1.04-1.68, p = 0.02). Hispanic patients had a higher incidence of acute kidney injury requiring dialysis when compared to NHW patients (OR: 2.53, 95% CI: 1.11-5.77, p = 0.027). There was no significant difference in terms of in-hospital mortality between NHB and Hispanic patients when compared to NHW patients. Notably, Hispanic populations experienced a higher mortality rate during the COVID-19 period. CONCLUSION: Our study suggested significant differences in the outcomes of TTS across different racial groups. Hispanic populations experienced a higher mortality rate with TTS during the COVID-19 era. Further research should emphasize discovering the factors contributing to the observed disparities.

Inappropriate prescribing and association with readmission or mortality in hospitalised older adults with frailty: a systematic review and meta-analysis.

BACKGROUND: Inappropriate prescribing (IP) is common in hospitalised older adults with frailty. However, it is not known whether the presence of frailty confers an increased risk of mortality and readmissions from IP nor whether rectifying IP reduces this risk. This review was conducted to determine whether IP increases the risk of adverse outcomes in hospitalised middle-aged and older adults with frailty. METHODS: A systematic review was conducted on IP in hospitalised middle-aged (45-64 years) and older adults (≥ 65 years) with frailty. This review considered multiple types of IP including potentially inappropriate medicines, prescribing omissions and drug interactions. Both observational and interventional studies were included. The outcomes were mortality and hospital readmissions. The databases searched included MEDLINE, CINAHL, EMBASE, World of Science, SCOPUS and the Cochrane Library. The search was updated to 12 July 2024. Meta-analysis was performed to pool risk estimates using the random effects model. RESULTS: A total of 569 studies were identified and seven met the inclusion criteria, all focused on the older population. One of the five observational studies found an association between IP and emergency department visits and readmissions at specific time points. Three of the observational studies were amenable to meta-analysis which showed no significant association between IP and hospital readmissions (OR 1.08, 95% CI 0.90-1.31). Meta-analysis of the subgroup assessing Beers criteria medicines demonstrated that there was a 27% increase in the risk of hospital readmissions (OR 1.27, 95% CI 1.03-1.57) with this type of IP. In meta-analysis of the two interventional studies, there was a 37% reduced risk of mortality (OR 0.63, 95% CI 0.40-1.00) with interventions that reduced IP compared to usual care but no difference in hospital readmissions (OR 0.83, 95% CI 0.19-3.67). CONCLUSIONS: Interventions to reduce IP were associated with reduced risk of mortality, but not readmissions, compared to usual care in older adults with frailty. The use of Beers criteria medicines was associated with hospital readmissions in this group. However, there was limited evidence of an association between IP more broadly and mortality or hospital readmissions. Further high-quality studies are needed to confirm these findings.

Insights into hospitalization pattern for drug, medicament, and biological substance poisoning, adverse effect, and underdosing in Australia: An ecological study between 1998 and 2019.

BACKGROUND: Drug, medicament, and biological substance poisoning, adverse effects, and underdosing are significant public health concerns. Gaining insight into the patterns and trends in hospitalizations caused by these occurrences is essential for the development of preventative initiatives, optimization of treatment regimens, and improvement of patient safety. The aim of this study is to examine the trend of hospitalisation related to poisoning by, adverse effect of and underdosing of drugs, medicaments and biological substances in Australia between 1998 and 2019. METHODS: This is an ecological descriptive study that examined hospitalisation related to poisoning by, adverse effect of and underdosing of drugs, medicaments and biological substances in Australia between 1998 and 2019. A nationwide hospital admissions database was used for this study. RESULTS: Between 1998 and 2019, a total of 683,869 hospital admission episodes were recorded in Australia. The overall annual number of hospital admissions for various reasons increased by 20.5% from 29,854 in 1998 to 35,960 in 2019, representing a decrease in hospital admission rate of 10.6% [from 158.69 (95% CI 156.90-160.49) in 1998 to 141.91 (95% CI 140.44-143.37) in 2019 per 100,000 persons, trend test, p<0.05]. Overnight-stay admissions accounted for 69.2% of the total number of hospital admissions, and 30.8% were same-day admissions. Rates of same-day hospital admission decreased by 13.3% [from 50.55 (95%CI 49.54-51.57) in 1998 to 43.81 (95%CI 43.00-44.63) in 2019 per 100,000 persons]. Rates of overnight-stay hospital admission decreased by 11.1% [from 108.14 (95%CI 106.66-109.63) in 1998 to 96.17 (95%CI 94.96-97.38) in 2019 per 100,000 persons]. Admissions related to antiepileptic, sedative-hypnotic and antiparkinsonism drugs was the most prevalent hospital admissions type accounting for 26.8%. Females were responsible for 418,751 hospital admission episodes, representing 61.5% of the total number of hospital admission. CONCLUSION: This study found that while the overall annual number of admissions increased, the rate of admission decreased over the same period. The most common reasons for admissions were antiepileptic, sedative-hypnotic, and anti-parkinsonism drugs. The study also noted increases in admissions related to anaesthetics, therapeutic gases, hormones, and their synthetic substitutes. These findings suggest a concerning rise in the suboptimal use of these medications. In order to combat the increasing incidence of this type of admissions, it is imperative to strengthen public awareness initiatives on medicine safety and abuse.

Increasing trend in patients with life-limiting and complex chronic conditions.

INTRODUCTION AND OBJECTIVES: To estimate the frequency of patients with diagnoses associated with life-limiting conditions (LLCs) or complex chronic conditions (CCCs). METHODS: Retrospective mixed population-based and hospital-based cohort study. Study universe consisted of the population aged less than 18 years of an autonomous community in Spain in the 2001-2021 period; the cases were patients admitted to hospital with a diagnosis associated with LLC or CCC during this period. We estimated age-adjusted annual prevalences and analysed changes in trends using joinpoint regression. RESULTS: The prevalence of LLCs increased significantly from 20.7 per 10 000 inhabitants under 18 years in 2001 to 51.3 per 10 000 in 2019. There was also a significant increase in CCCs from 39.9 per 10 000 in 2001 to 54.4 per 10 000 in 2019. The prevalence of patients with any of these conditions rose from 45 per 10 000 in 2001 to 86.8 per 10 000 in 2019; 30.3% of these patients had conditions of both types. There was a turning point in this increasing trend between 2019 and 2020, coinciding with the COVID-19 pandemic. CONCLUSIONS: The prevalence of patients requiring specialized care has increased progressively in the last 20 years, similar to what has happened in other countries. The magnitude of the affected population must be taken into account when planning specialized paediatric palliative care and complex chronic care services.

Emergency department utilization among adults with epilepsy: A multi-state cross-sectional analysis, 2010-2019.

OBJECTIVE: We described patterns and trends in ED use among adults with epilepsy in the United States. METHODS: Utilizing inpatient and ED discharge data from seven states, we conducted a cross-sectional analysis to identify adult ED visits diagnosed with epilepsy or seizures from 2010 to 2019. Using ED visit counts and estimates of state-level epilepsy prevalence, we calculated ED visit rates overall and by payer, condition, and year. RESULTS: Our data captured 304,935 ED visits with epilepsy as a primary or secondary diagnosis in 2019. Across the seven states, visit rates ranged between 366 and 726 per 1000 and were higher than rates for adults without epilepsy in all states but one. ED visit rates were highest among Medicare and Medicaid beneficiaries (vs commercial or self-pay). Adults with epilepsy were more likely to be admitted as inpatients. Visits for nervous system disorders were 6.3-8.2 times higher among people with epilepsy, and visits for mental health conditions were 1.2-2.6 times higher. Increases in ED visit rates from 2010 to 2019 among people with epilepsy exceeded increases among adults without by 6.0-27.3 percentage points. CONCLUSION: Adults with epilepsy visit the ED frequently and visit rates have been increasing over time. These results underscore the importance of identifying factors contributing to ED use and designing tailored interventions to improve ambulatory care quality.

Trends in youth acute care hospital visits for anxiety and depression in Illinois.

PURPOSE: This study analyzes the trajectory of youth emergency department or inpatient hospital visits for depression or anxiety in Illinois before and during the COVID-19 pandemic. METHODS: We analyze emergency department (ED) outpatient visits, direct admissions, and ED admissions by patients ages 5-19 years coded for depression or anxiety disorders from 2016 through June 2023 with data from the Illinois Hospital Association COMPdata database. We analyze changes in visit rates by patient sociodemographic and clinical characteristics, hospital volume and type, and census zip code measures of poverty and social vulnerability. Interrupted times series analysis was used to test the significance of differences in level and trends between 51 pre-pandemic months and 39 during-pandemic months. RESULTS: There were 250,648 visits to 232 Illinois hospitals. After large immediate pandemic decreases there was an estimated -12.0 per-month (p = 0.003, 95% CI -19.8-4.1) decrease in male visits and a - 13.1 (p = 0.07, 95% CI -27 -1) per-month decrease in female visits in the during-pandemic relative to the pre-pandemic period. The reduction was greatest for outpatient ED visits, for males, for age 5-9 and 15-19 years patients, for smaller community hospitals, and for patients from the poorest and most vulnerable zip code areas. CONCLUSIONS: llinois youth depression and anxiety hospital visit rates declined significantly after the pandemic shutdown and remained stable into 2023 at levels below 2016-2019 rates. Further progress will require both clinical innovations and effective prevention grounded in a better understanding of the cultural roots of youth mental health.

Population-level trends in self-reported healthcare utilization among older adults in Mexico with and without cognitive impairment.

BACKGROUND: Older adults with cognitive impairment exhibit different patterns of healthcare utilization compared to their cognitively healthy counterparts. Despite extensive research in high-income countries, similar studies in low- and middle-income countries are lacking. This study aims to investigate the population-level patterns in healthcare utilization among older adults with and without cognitive impairment in Mexico. METHODS: Data came from five waves (2001-2018) of the Mexican Health and Aging Study. We used self-reported measures for one or more over-night hospital stays, doctor visits, visits to homeopathic doctors, and dental visits in the past year; seeing a pharmacist in the past year; and being screened for cholesterol, diabetes, and hypertension in the past two years. Cognitive impairment was defined using a modified version of the Cross Cultural Cognitive Examination that assessed verbal memory, visuospatial and visual scanning. Total sample included 5,673 participants with cognitive impairment and 34,497 without cognitive impairment interviewed between 2001 and 2018. Generalized Estimating Equation models that adjusted for time-varying demographic and health characteristics and included an interaction term between time and cognitive status were used. RESULTS: For all participants, the risk for one or more overnight hospital stays, doctor visits, and dental visits in the past year, and being screened for diabetes, hypertension, and high cholesterol increased from 2001 to 2012 and leveled off or decreased in 2015 and 2018. Conversely, seeing a homeopathic doctor decreased. Cognitive impairment was associated with higher risk of hospitalization (RR = 1.13, 1.03-1.23) but lower risk of outpatient services (RR = 0.95, 0.93-0.97), cholesterol screening (RR = 0.93, 0.91-0.96), and diabetes screening (RR = 0.95, 0.92-0.97). No significant difference was observed in the use of pharmacists, homeopathic doctors, or folk healers based on cognitive status. Interaction effects indicated participants with cognitive impairment had lower risk for dental visits and hypertension screening but that these trajectories differed over time compared to participants without cognitive impairment. CONCLUSIONS: We identified distinct population-level trends in self-reported healthcare utilization and differences according to cognitive status, particularly for elective and screening services. These findings highlight the necessity for policy interventions to ensure older adults with cognitive impairment have their healthcare needs met.

Trends in hospitalization for cardio-renal disease and mortality in people with type 1 diabetes in England, 2009-2019.

AIM: To assess mortality and complication trends in people with type 1 diabetes during the 11 years before the SARS-CoV2 pandemic (2009-2019). MATERIALS AND METHODS: Sequential cohorts of people in England with type 1 diabetes aged ≥20 years from the National Diabetes Audit (2006/2007 to 2016/2017) were analysed. Discretized Poisson regression models, adjusted for age, sex, ethnicity, socioeconomic deprivation and duration of diabetes, were used to calculate mortality and hospitalization rates. RESULTS: Demographic characteristics changed little; average diabetes duration increased. All-cause mortality was unchanged. Cardiovascular and kidney disease mortality declined. Mortality from respiratory disease, diabetes and dementia increased in younger people (aged 20-74 years) as did mortality from liver disease and dementia in the elderly (aged ≥75 years). Younger Asian and Black people had lower all-cause mortality than those of White ethnicity; elderly Mixed, Asian and Black people had lower all-cause mortality. People from more deprived areas had higher all-cause mortality. The deprivation gradient for mortality was steeper at younger ages. In younger people, rates of hospitalization increased for myocardial infarction, stroke, heart failure and kidney disease but only for kidney disease in the elderly. Rates of a composite measure of cardiovascular hospitalizations increased in younger people (rate ratio [RR] 1.07, 95% confidence interval [CI] 1.03-1.11) but declined in the elderly (RR 0.91, 95% CI 0.86-0.95). CONCLUSION: Between 2009 and 2019, hospitalizations for cardiovascular disease increased at younger ages (20-74 years) and hospitalizations for kidney disease increased at all ages, but mortality from cardiovascular and kidney disease declined. All-cause mortality rates were unchanged.

The Relationship Between Pre-Pandemic Comorbidities With SARS-CoV-2 Infections and Hospitalizations in Black Versus White Military Service Members: A Retrospective Study.

INTRODUCTION: Comorbidities such as hypertension, diabetes mellitus, asthma, and cardiovascular conditions have been reported to worsen the clinical progression of coronavirus disease 2019 (COVID-19) and related hospitalizations. Furthermore, the COVID-19 pandemic has disproportionately affected the historically marginalized groups, i.e., Black, Hispanic, and Asian individuals have substantially higher rates of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection, COVID-19 hospitalization, and death compared to White individuals. Despite these findings in civilian populations, the impact of comorbidities and race in SARS-CoV-2 infection and COVID-19 hospitalizations in military populations is unknown. We evaluated the relationship of pre-selected pre-pandemic comorbidities and race with SARS-CoV-2 infections and COVID-19 hospitalizations in U.S. military service members (SMs). MATERIALS AND METHODS: We conducted a systematic review of Military Health System beneficiaries' records by accessing the Defense Medical Epidemiological Database. Our inclusion criteria were being an active duty SM and having at least one pre-COVID-19 pandemic comorbidity. Retired as well as uninfected healthy active duty SMs and beneficiaries were excluded from the study. A total population of 1.334 million active duty SM records was drawn from Defense Medical Epidemiological Database. The data were stratified, by race (primary outcome), as well as gender, age, and military service branches (secondary outcomes). RESULTS: We found higher trends in SARS-CoV-2 infection and COVID-19 hospitalization rates in Black compared to White SMs. This seamless inequality was also seen in other viral infections affecting SMs including human immunodeficiency virus and viral hepatitis. We hypothesized this disparity to some extent be associated with the presence of pre-pandemic comorbidities that is affecting this military subpopulation. Supporting our hypothesis, we found trends toward the higher pre-pandemic prevalence of diabetes mellitus, asthma, hypertension, and ischemic heart disease, in Black compared to White military SMs, especially in Black older male adults. CONCLUSION: Our results highlight the role of pre-pandemic comorbidities and race likely enhancing the frequency of SARS-CoV-2 infections and COVID-19 hospitalizations in military SMs. These preliminary findings underscore the need for future retrospective studies using additional Military Health System data bases reporting data on this military subpopulation, especially in the setting of future pathogens outbreaks or pandemics affecting military populations.

Association between frailty and hypoproteinaemia in older patients: meta-analysis and systematic review.

OBJECTIVE: Frailty and hypoproteinaemia are common in older individuals. Although there is evidence of a correlation between frailty and hypoproteinaemia, the relationship between frailty and hypoproteinaemia in hospitalized/critically ill and older community residents has not been clarified. Therefore, the aim of our meta-analysis was to evaluate the associations between frailty and hypoproteinaemia in different types of patients. METHODS: A systematic retrieval of articles published in the PubMed, Embase, Medline, Web of Science, Cochrane, Wanfang, and CNKI databases from their establishment to April 2024 was performed to search for studies on the associations between severity of frailty or prefrailty and hypoproteinaemia in older adults. The Newcastle‒Ottawa Scale and the Agency for Healthcare Research and Quality Scale were used to assess study quality. RESULTS: Twenty-two studies were included including 90,351 frail older people were included. Meta-analysis revealed an association between frailty or prefrailty and hypoproteinaemia (OR = 2.37, 95% CI: 1.47, 3.83; OR = 1.62, 95% CI: 1.23, 2.15), there was no significant difference in the risk of hypoproteinaemia between patients with severe frailty and those with low or moderate frailty (OR = 0.62, 95% CI:0.44, 0.87). The effect of frailty on the occurrence of hypoproteinaemia was more obvious in hospitalized patients/critically ill patients than in surgical patients (OR = 3.75, 95% CI: 2.36, 5.96), followed by older community residents (OR = 2.30, 95% CI: 1.18, 4.49). CONCLUSION: Frailty is associated with hypoproteinaemia in surgical patients, hospitalized older patients and older community residents. Future studies should focus on the benefits of albumin supplementation in preventing or alleviating frailty and related outcomes in the future.

Age- and Sex-Specific Analysis of Stroke Hospitalization Rates, Risk Factors, and Outcomes From German Nationwide Data.

BACKGROUND: Significant age and sex differences have been reported at each stage of the stroke pathway, from risk factors to outcomes. However, there is some uncertainty in previous studies with regard to the role of potential confounders and selection bias. Therefore, using German nationwide administrative data, we aimed to determine the magnitude and direction of trends in age- or sex-specific differences with respect to admission rates, risk factors, and acute treatments of ischemic and hemorrhagic stroke. METHODS: We obtained and analyzed data from the Research Data Centres of the Federal Statistical Office for the years 2010 to 2020 with regard to all acute stroke hospitalizations, risk factors, treatments, and in-hospital mortality, stratified by sex and stroke subtype. This database provides a complete national-level census of stroke hospitalizations combined with population census counts. All hospitalized patients ≥15 years with an acute stroke (diagnosis code: I60-64) were included in the analysis. RESULTS: Over the 11-year study period, there were 3 375 157 stroke events; 51.2% (n=1 728 954) occurred in men. There were higher rates of stroke admissions in men compared with women for both ischemic (378.1 versus 346.7/100 000 population) and hemorrhagic subtypes (75.6 versus 65.5/100 000 population) across all age groups. The incidence of ischemic stroke admissions peaked in 2016 among women (354.0/100 000 population) and in 2017 among men (395.8/100 000 population), followed by a consistent decline from 2018 onward. There was a recent decline in hemorrhagic stroke admissions observed for both sexes, reaching its nadir in 2020 (68.9/100 000 for men; 59.5/100 000 for women). Female sex was associated with in-hospital mortality for both ischemic (adjusted odds ratio, 1.11 [1.09-1.12]; P<0.001) and hemorrhagic stroke (adjusted odds ratio, 1.18 [95% CI, 1.16-1.20]; P<0.001). CONCLUSIONS: Despite improvements in stroke prevention and treatment pathways in the past decade, sex-specific differences remain with regard to hospitalization rates, risk factors, and mortality. Better understanding the mechanisms for these differences may allow us to develop a sex-stratified approach to stroke care.

Trends in the burden of hospitalised patients with cirrhosis in Switzerland: a cross-sectional study of cirrhosis-related hospitalisations between 1998 and 2020.

OBJECTIVE: Liver cirrhosis is an increasing cause of morbidity and mortality worldwide with a heavy load on healthcare systems. We analysed the trends in hospitalisations for cirrhosis in Switzerland. DESIGN: Cross-sectional study. SETTING: Large nationwide inpatient database, years between 1998 and 2020. PARTICIPANTS: Hospitalisations for cirrhosis of adult patients were selected. MAIN OUTCOMES AND MEASURES: Hospitalisations with either a primary diagnosis of cirrhosis or a cirrhosis-related primary diagnosis with a mandatory presence of cirrhosis as a secondary diagnosis were considered following the 10th revision of the International Statistical Classification of Diseases and Related Health Problems codes. Trends in demographic and clinical characteristics, in-hospital mortality and length of stay were analysed. Causes and costs of cirrhosis-related hospitalisations were available from 2012 onwards. RESULTS: Cirrhosis-related hospitalisations increased from 1631 in 1998 to 4052 in 2020. Of the patients, 68.7% were men. Alcohol-related liver disease was the leading cause, increasing from 44.1% (95% CI, 42.4% to 45.9%) in 2012 to 47.9% (95% CI, 46.4% to 49.5%) in 2020. Assessed by exclusion of other coded causes, non-alcoholic fatty liver disease was the second cause at 42.7% (95% CI, 41.2% to 44.3%) in 2020. Hepatitis C virus-related cirrhosis decreased from 12.3% (95% CI, 11.2% to 13.5%) in 2012 to 3.2% (95% CI, 2.7% to 3.8%) in 2020. Median length of stay decreased from 11 to 8 days. Hospitalisations with an intensive care unit stay increased from 9.8% (95% CI, 8.4% to 11.4%) to 15.6% (95% CI, 14.5% to 16.8%). In-hospital mortality decreased from 12.1% (95% CI, 10.5% to 13.8%) to 9.7% (95% CI, 8.8% to 10.7%). Total costs increased from 54.4 million US$ (51.4 million €) in 2012 to 92.6 million US$ (87.5 million €) in 2020. CONCLUSIONS: Cirrhosis-related hospitalisations and related costs increased in Switzerland from 1998 to 2020 but in-hospital mortality decreased. Alcohol-related liver disease and non-alcoholic fatty liver disease were the most prevalent and preventable aetiologies of cirrhosis-related hospitalisations.

Trends in Mortality After Incident Hospitalization for Heart Failure Among Medicare Beneficiaries.

Importance: Despite advances in treatment and care quality for patients hospitalized with heart failure (HF), minimal improvement in mortality has been observed after HF hospitalization since 2010. Objective: To evaluate trends in mortality rates across specific intervals after hospitalization. Design, Setting, and Participants: This cohort study evaluated a random sample of Medicare fee-for-service beneficiaries with incident HF hospitalization from January 1, 2008, to December 31, 2018. Data were analyzed from February 2023 to May 2024. Main Outcomes and Measures: Unadjusted mortality rates were calculated by dividing the number of all-cause deaths by the number of patients with incident HF hospitalization for the following periods: in-hospital, 30 days (0-30 days after hospital discharge), short term (31 days to 1 year after discharge), intermediate term (1-2 years after discharge), and long term (2-3 years after discharge). Each period was considered separately (ie, patients who died during one period were not counted in subsequent periods). Annual unadjusted and risk-adjusted mortality ratios were calculated (using logistic regression to account for differences in patient characteristics), defined as observed mortality divided by expected mortality based on 2008 rates. Results: A total of 1 256 041 patients (mean [SD] age, 83.0 [7.6] years; 56.0% female; 86.0% White) were hospitalized with incident HF. There was a substantial decrease in the mortality ratio for the in-hospital period (unadjusted ratio, 0.77; 95% CI, 0.67-0.77; risk-adjusted ratio, 0.74; 95% CI, 0.71-0.76). For subsequent periods, mortality ratios increased through 2013 and then decreased through 2018, resulting in no reductions in unadjusted postdischarge mortality during the full study period (30-day mortality ratio, 0.94; 95% CI, 0.82-1.06; short-term mortality ratio, 1.02; 95% CI, 0.87-1.17; intermediate-term mortality ratio, 0.99; 95% CI, 0.79-1.19; and long-term mortality ratio, 0.96; 95% CI, 0.76-1.16) and small reductions in risk-adjusted postdischarge mortality during the full study period (30-day mortality ratio, 0.88; 95% CI, 0.86-0.90; short-term mortality ratio, 0.94; 95% CI, 0.94-0.95; intermediate-term mortality ratio, 0.94; 95% CI, 0.92-0.95; and long-term mortality ratio, 0.95; 95% CI, 0.93-0.96). Conclusions and Relevance: In this study of Medicare fee-for-service beneficiaries, there was a substantial decrease in in-hospital mortality for patients hospitalized with incident HF from 2008 to 2018, but little to no reduction in mortality for subsequent periods up to 3 years after hospitalization. These results suggest opportunities to improve longitudinal outpatient care for patients with HF after hospital discharge.
