Changing Trends in Child and Adolescent Psychiatric Admissions During COVID-19: A Retrospective Cross-sectional Study at a Tertiary Center in Turkey

Changing Trends in Child and Adolescent Psychiatric Admissions During COVID-19: A Retrospective Cross-sectional Study at a Tertiary Center in Turkey

Tetanus in Uganda: Clinical Outcomes of Adult Patients Hospitalized at a Tertiary Health Facility Between 2011 and 2020.

BackgroundTetanus is a vaccine-preventable infectious disease associated with high mortality rates. Increased vaccination coverage globally and locally has resulted in substantial declines in the number of individuals diagnosed with tetanus. We report annual trends in tetanus admissions and deaths over a decade at a national referral hospital in Uganda.MethodsThis was a retrospective cohort study, using data from an electronic database of patients admitted to medical wards at a national referral hospital between 2011 and 2020. Data were abstracted on demographic characteristics, that is, length of hospital stay and mortality outcome. Admission and mortality rate trends were analyzed using the Mann-Kendall’s trend test, whereas Kaplan-Meier survival curves were used to compare gender survival rates.ResultsDuring the study period, 459 individuals were admitted with tetanus. Of these, 85.8% (394 of 459) were males, and 26.1% (120 of 459) were aged 20 years or less. Overall, 48.8% (224 of 459) participants died, 85.3% (191 of 224) of whom were males (85.3%, n = 191), although females had a higher mortality rate (50.8%, 33 of 65 vs 48.5%, 191 of 394). Those aged 31–40 years accounted for 23.7% (53 of 224) of the deaths; and 88.7% (197 of 224) of the deaths occurred within the first 7 days of admission. The total number of tetanus admissions declined (TauA = −.6444, P = .0116). However, mortality rates remained stable (TauA = .0222, P > .999). The average length of hospital stay was 8.1 days (standard deviation, 7.5; range, 1–46).ConclusionsAlthough tetanus admissions declined, mortality rate remained high. Males were disproportionately affected. We recommend quality-of-care audits for inpatient care improvement and more research on the determinants of infection and mortality to inform vaccination for at-risk men.

Trends in Thoracic Aortic Aneurysm Hospital Admissions, Interventions, and Mortality in England between 1998 and 2020: An Observational Study

To assess trends in thoracic aortic aneurysm (TAA) hospital admissions, interventions, and aneurysm related mortality (ARM) in England, and examine the impact of endovascular repair on mortality for the years 1998 to 2020. Hospital admission and operative approach (thoracic endovascular aortic repair, [TEVAR] or open surgical repair) using Hospital Episodes Statistics, and ARM data from the Office for National Statistics for England standardised to the 2013 European Standard Population were analysed using linear regression and Joinpoint regression analyses. ARM was compared between the pre-endovascular era (1998 - 2008) and the endovascular era (2009 - 2019). A rising trend in hospital admission incidence has been observed, mainly due non-ruptured admissions (4.11 per 100 000 in 1998; 95% confidence interval (CI) 3.71 - 4.50 to 12.61 per 100 000 in 2020; 95% CI 12.00 - 13.21 in 2020; r2= .98; p < .001). Operative interventions increased mainly due to an increase in TEVAR (2.15 per 100 000; 95% CI 1.91 - 2.41 in 2020 vs. 0.26 per 100 000; 95% CI 0.16 - 0.36 in 2006; r2= .90; p < .001). Reductions in ARM from TAA were observed for males and females, irrespective of age and rupture status. The greatest reduction in ARM in the endovascular era was observed in females aged > 80 years with ruptured disease (15.26 deaths per 100 000 vs. 9.50 deaths per 100 000; p < .001). A significant increase in hospital admissions for non-ruptured TAA has been observed in the last 23 years in England, paralleled by a shift towards endovascular repair, and significant declining trends in ARM, irrespective of sex and age. The significant reductions in age standardised death rates from ruptured and non-ruptured TAA in the endovascular era, particularly for females aged > 80 years with ruptured disease, affirm the positive impact of an endovascular approach to TAA.

Quality of care in people requiring hospital admission for gout in Aotearoa New Zealand: a nationwide analysis.

The quality of care for patients admitted with a primary diagnosis of gout, both before and after admission, has not been systematically examined. To understand national trends in hospital admission for a primary diagnosis of gout in Aotearoa New Zealand over the past 10 years and the quality of care for gout received by these patients before and after the admission. Data from the Aotearoa New Zealand National Collections from 1 January 2007 to 31 December 2019 were analysed to determine rates of hospital admission for a primary diagnosis of gout. Admission data include cost-weight analysis, as well as quality of care data including gout-specific medication dispensing in the year prior and year after admission. There were 13 721 admissions with a primary diagnosis of gout over the analysis period, with an average cost per admission in 2019 of NZ$4301. The rate of admission per 100 000 population was highest in Pacific peoples followed by Māori. Although dispensing of any allopurinol increased in the year after admission, rates of regular allopurinol dispensing remained low; 38.1% for admissions in 2018. Patients who were younger (especially 20-44 years), not enrolled in a primary health organisation before admission and female had lower rate of regular allopurinol after admission. In this nationwide study, rates of admission for gout were highest in Pacific peoples and in Māori. Rates of regular allopurinol dispensing were low even after admission for a primary diagnosis of gout. These findings highlight the need for improvements in gout management in Aotearoa New Zealand, including in post-discharge planning from secondary care inpatient services.

A retrospective analysis of 3 156 admissions with fever of unknown origin in a large Italian hospital

&#x0D; Background: fever of unknown origin (FUO) is defined as a fever with no etiologic diagnosis after standardized investigations performed during 3 days in hospital or after at least 3 ambulatory visits. Our study aims to describe the epidemiology of classic FUO through the retrospective analysis of 902 861 admissions to a large University Hospital in Italy, to investigate its temporal trend, and to evaluate differences between young and old patients.&#x0D; Methods: we retrieved data records of all the admissions between the 1st January 1988 and 31st December 2007. Proportional admission rate (PAR ) of FUO was calculated. Time trends of FUO admissions were analysed by joinpoint regression, with time changes expressed as Expected Annual Percent Change (EA PC). The ICD 9-CM code was used to identify the diagnosis on discharge of FUO cases.&#x0D; Results: in the study period 3 156 patients were admitted with a diagnosis of FUO (PAR=3.50 per 1 000). The time-trend analysis showed two joinpoints, the first in 1995 (EAPC of 307.80, 95% CI: 89.66-776.84, p=0.002), and the second in 1998 (EAPC=-8.57, 95% CI: -10.37-6.73; p&lt;0.001). Around 22% of admissions remained without a definitive diagnosis of FUO, with this percentage being lower in patients ≥65 years compared with subjects aged 21-64.&#x0D; Conclusions: FUO is a leading cause of admission to hospitals, as well as of morbidity and mortality, thus representing a challenge for diagnostic medicine and hospital care. It is necessary to develop a diagnostic methodology for FUO , so as to reduce costs of preventable hospitalizations.&#x0D;

Admission trends on AMU: an opportunity in a pandemic

Trends in Hospital Admissions Due to Neoplasms in England and Wales between 1999 and 2019: An Ecological Study.

Objectives: This study aimed to investigate the trends in neoplasm-related hospital admissions (NRHA) in England and Wales between 1999 and 2019. Methods: This is an ecological study using publicly available data taken from the two main medical databases in England and Wales; the Hospital Episode Statistics database in England and the Patient Episode Database in Wales. Hospital admissions data were collected for the period between April 1999 and March 2019. Results: A total of 35,704,781 NRHA were reported during the study period. Females contributed to 50.8% of NRHA. The NRHA rate among males increased by 50.0% [from 26.62 (95% CI 26.55–26.68) in 1999 to 39.93 (95% CI 39.86–40.00) in 2019 per 1000 persons, trend test, p < 0.001]. The NRHA rate among females increased by 44.1% [from 27.25 (95% CI 27.18–27.31) in 1999 to 39.25 (95% CI 39.18–39.32) in 2019 per 1000 persons, trend test, p < 0.001]. Overall, the rate of NRHA rose by 46.2% [from 26.93 (95% CI 26.89–26.98) in 1999 to 39.39 (95% CI 39.34–39.44) in 2019 per 1000 persons, trend test, p < 0.001]. Conclusion: Hospital admission rates due to neoplasms increased between 1999 and 2019. Our study demonstrates a variation in NRHA influenced by age and gender. Further observational studies are needed to identify other factors associated with increased hospital admissions among patients with different types of neoplasms.

16-year trends in asthma hospital admissions in Canada

BackgroundAsthma hospitalizations declined rapidly in many parts of the world, including Canada, in the 1990s and early 2000s. ObjectiveTo examine whether the declining trend of asthma hospitalizations persisted in recent years in Canada. MethodsUsing the Canadian comprehensive nationwide hospitalization data (2002-2017), we identified hospital admissions with the main International Classification of Diseases codes for asthma. We analyzed sex-specific age-standardized trends in annual hospitalization rates among pediatric (< 19 years) and adult (19+ years) patients. We used change-point analysis to evaluate any substantial changes in the trends in the sex-age groups. ResultsThere were 254,672 asthma-related hospital admissions (59% pediatric, 50% female) during the study period. Among children, age-adjusted annual rates per 100,000 decreased by 55% in females (152-69) and by 60% in males (270-108) from 2002 to 2017. Among adults, the rates decreased by 59% in both sexes (females: 61-25; males: 27-11). Change-point analysis indicated a substantial plateauing of the annual rate in both pediatric (from −15.3 [females] and −25.8 [males] before 2010 to −0.6 [females] and −0.8 [males] after 2010) and adult (from −5.4 [females] and −2.6 [males] before 2008 to −0.6 [females] and −0.2 [males] after 2008) groups. ConclusionAfter a substantial decline in hospital admissions for acute asthma, there has been minimal further decline since 2010 for children and 2008 for adults. In addition to adhering to the contemporary standards of asthma care, novel, disruptive strategies are likely needed to further reduce the burden of asthma.

Temporal trends in clinical characteristics and in-hospital mortality among patients with COVID-19 in Japan for waves 1, 2, and 3: A retrospective cohort study

IntroductionLittle information is available on the temporal trends in the clinical epidemiology and in-hospital mortality of patients with coronavirus disease 2019 (COVID-19) in Japan for waves 1, 2, and 3. MethodsA national claims database was used to analyze the time trends in admission, medical procedure, and in-hospital mortality characteristics among patients with COVID-19. Patients who were ≥18 years and discharged from January 1, 2020 to February 28, 2021 were included. ResultsA multilevel logistic regression analysis of 51,252 patients revealed a decline in mortality in waves 2 and 3 (risk-adjusted mortality range = 2.17–4.07%; relative risk reduction = 23–59%; reference month of April 2020 = 5.32%). In the subgroup analysis, a decline in mortality was also observed in patients requiring oxygen support but not mechanical ventilation (risk-adjusted mortality range = 5.98–11.68%; relative risk reduction = 22–60%; reference month of April 2020 = 15.06%). Further adjustments for medical procedure changes in the entire study population revealed a decrease in mortality in waves 2 and 3 (risk-adjusted mortality range = 2.66–4.05%; relative risk reduction = 24–50%). ConclusionsA decline in in-hospital mortality was observed in waves 2 and 3 after adjusting for patient/hospital-level characteristics and medical treatments. The reasons for this decline warrant further research to improve the outcomes of hospitalized patients.

Antibiotic use among admitted pediatric patients in the United States with status asthmaticus before and during the COVID-19 pandemic

Objective: Hospital admission trends of children with status asthmaticus diminished during the Coronavirus-19 (COVID-19) pandemic of 2020, possibly secondary to several factors such as school closures and use of face masks. What effect this had on antibiotic prescribing practices has yet to be described. The objective of our study was to evaluate the use of antibiotics in hospitalized children with a diagnosis of status asthmaticus before and during the COVID pandemic.Methods: A retrospective cross-sectional analysis was conducted using the TriNetX® cloud-based program with a national and institutional database. Each database was queried for all inpatient pediatric encounters from 3 to 18 years old, admitted with a diagnosis of status asthmaticus in the spring seasons of 2017–2019. Admission data and antibiotic usage were queried during the COVID-19 pandemic year of 2020 from both databases and compared amongst all study years.Results: In 2020, there was an overall decrease in the number of admissions as compared to the average number from 2017–2019, by 76.9% in the national database (p < 0.05) and 91.2% in the institutional database. The rates of antibiotic prescriptions significantly dropped among the national database (p < 0.001, z = 3.39) and remained non-significantly changed among the institutional database (p = 0.944 and z = 0.073).Conclusions: Our study demonstrates that the COVID-19 pandemic year of 2020 coincided with a significant decrease in hospital admissions and antibiotic prescribing prevalence among children with status asthmaticus on a national level. Nonetheless, our reported trends in antibiotic prescribing are still grossly similar to that of pre-pandemic times and may demonstrate a continued need for antimicrobial stewardship.

Temporal trends in non-traumatic lower extremity amputations (LEAs) and their association with 12-month mortality in people with diabetes, 2004–2016

AimsTo assess trends in hospital admissions for non-traumatic lower extremity amputations (LEAs) and for mortality following LEAs in adult patients with type 1 diabetes (T1DM) or type 2 diabetes (T2DM) admitted to hospitals in Victoria, Australia during 2004–2016. MethodsUsing hospital discharge data, we calculated age- and sex- adjusted admission rates for incident cases of any LEA, minor LEAs, major LEAs and 12-month mortality following any LEAs for patients according to diabetes type. Joinpoint regression analysis was used to identify changes in linear trends that were described as average annual percentage change (AAPC). ResultsSignificant declines in rates of admission for any LEA (AAPC −4.9), minor LEAs (−3.0 %) and major LEAs (AAPC -11.5 %) were seen for patients with T2DM. Overall, admission rates for any LEA did not significantly change for patients with T1DM during 2004 and 2016, however, we detected a significant rise in admissions for any LEAs (AAPC +5.1) in female patients with T1DM. This increase was most prominent in younger (<60 years) patients undergoing minor LEAs. During 2009–2016, younger patients with type 1 DM, regardless of sex, also experienced significant increases in admissions for any LEA (AAPC +14) and major LEAs (AAPC +15). Mortality associated with LEAs in T2DM declines, with a 12-month mortality rate of 6.3 %) associated with LEAs in T2M decline (AAPC -4.2 %) whereas rates for T1DM remained stable (1.9 %) during 2004–2016. ConclusionsThere were significant differences in LEA hospital admission trends by type of diabetes, age and sex. The decline in LEAs and its associated mortality is welcome news for patients with T2DM. However, reasons for the increase in LEAs in younger patients with T1DM remain to be determined.

Pattern and Trends in Adult Hospitalization/Admission and Mortality Among Medical Ward Inpatients at Gadarif Hospital in Eastern Sudan: A Four-Year Retrospective Study.

PurposeSub-Saharan Africa suffers from a dual impact of communicable (CDs) and non-communicable diseases (NCDs). There is scarce data on causes, trends of admission, and deaths among patients in Sudan. We aimed to determine the causes, trends of admission, and mortality among adult patients admitted to Gadarif Hospital in Eastern Sudan.Patients and MethodsThe medical records of adult patients admitted to Gadarif medical wards from January 2017 to December 2020 were reviewed for age, gender, causes of admission, and outcomes. Multivariate Cox regression analysis was used to analysis factors (age, sex, years, and disease) associated with the mortality.ResultsOf the 7230 patients who were admitted, 2221 (34.7%) were females and 5009 (69.3%) were males. The median age (interquartile range, IQR) was 47.0 (35.0) years. Of these 7230 patients, 3167 (43.8%) and 4063 (56.2%) patients were admitted with CDs and NCDs, respectively. Cardiovascular diseases (18.4%), snakebites (12.9%), and visceral leishmaniasis (12.0%) were the most common causes of admission. The overall in-patient adult deaths were 674 (9.3%). Cardiovascular diseases (22.3%), neurological diseases (16.9%), sepsis (15.9%), renal diseases (13.9%), and snakebites (8.3%) were the most common causes of inpatient mortality. Malignancy (20.7%), sepsis (20.9%), neurological diseases (17.4%), and cardiovascular diseases (13.8%) comprised the highest case fatality rates among the admitted patients. Using a Cox regression model (adjusted), age (adjusted hazard ratio = 1.02, 95% confidence interval = 1.01‒1.03) was associated with increased mortality hazard. However, the gender and years of admission were not associated with increased mortality hazard.ConclusionAdmissions and mortality rates for CDs and NCDs are high compared with other African countries. Preventive measures are required to avert the high burden of these diseases. Health care systems in Sudan need to be prepared to deal with the dual burden of the diseases.

Service Evaluation of COVID and Non-COVID Admission Trends to an East Midlands General Adolescent Psychiatric Inpatient Unit

AimsTo explore the differences in admissions between the first COVID-19 lockdown cohort and a pre-COVID-19 cohort.Methods23 young people who were admitted to an East Midlands General Adolescent Inpatient Unit during the first COVID-19 lockdown from March 2020 to September 2020 were compared with the 48 young people who were admitted in the same period in 2019. Demographic details, admission duration and reasons, mental health act (MHA) status, diagnoses, functional status, and incidents were obtained retrospectively from the trust's online records.ResultsThe unit received more female admissions prior to lockdown (60.4% Vs 47.8%). Approximately 30% of adolescents in the pre-COVID-19 group were not in education whereas those admitted during COVID-19 were all receiving education. More of the pre-COVID-19 group attended school than college and more of the COVID-19 group were employed, consistent with a lower mean age of admission in the former group. Most of the COVID-19 admissions were local and none were out of area. Young people were also more likely to be looked after by their parents during COVID-19 (82.6%) and none were taken care of by their relatives.Pre-COVID019 admissions were discharged sooner than their counterparts, which had 13% of admissions between 6–9 months. Both cohorts had mainly informal admissions due to risk to self. Most of the COVID-19 admissions were due to anxiety, followed by self-harm while the majority of pre-COVID-19 admissions were due to depression and PTSD. 43% of the COVID-19 admissions had at least one comorbid diagnosis, notably depression. More adolescents in the COVID-19 cohort were not started on any psychiatric medication during and after admission.The mean number of incidents were two times higher in the COVID-19 group; self-harm was the most common reason. There was more violence towards staff during lockdown. However, absconsion, possession of contraband items, and staff error were higher in the pre-COVID-19 group.ConclusionThe introduction of COVID-19 restrictions was associated with a change in both the frequency and nature of inpatient admissions to this ward. Less young people were admitted during COVID-19, more frequently with anxiety as the primary reason and stayed for longer. Although the pre-COVID-19 group received more psychiatric medication, it is unclear if this contributed to a better functional status overall. This service evaluation also demonstrated the impact of COVID-19 on young people's mental health and life circumstances. An exploration of these trends in other units across the country would increase the generalisability of results.

Contemporary National Trends and Outcomes of Pulmonary Embolism in the United States

Contemporary data on the national trends in pulmonary embolism (PE) admissions and outcomes are scarce. We aimed to analyze trends in mortality and different treatment methods in acute PE. We queried the Nationwide Readmissions Database (2016 to 2019) to identify hospitalizations with acute PE using the International Classification of Diseases, Tenth Revision, Clinical Modification codes. We described the national trends in admissions, in-hospital mortality, readmissions, and different treatment methods in acute PE. We identified 1,427,491 hospitalizations with acute PE, 2.4% of them (n=34,446) were admissions with high-risk PE. The rate of in-hospital mortality in all PE hospitalizations was 6.5%, and it remained unchanged throughout the study period. However, the rate of in-hospital mortality in high-risk PE decreased from 48.1% in the first quarter of 2016 to 38.9% in the last quarter of 2019 (p-trend <0.001). The rate of urgent 30-day readmission was 15.2% in all PE admissions and 19.1% in high-risk PE admissions. In all PE admissions, catheter-directed interventions (CDI) were used more often (2.5%) than systemic thrombolysis (ST) (2.1%). However, in admissions with high-risk PE, ST remained the most frequently used method (ST vs CDI: 11.3% vs 6.6%). In conclusion, this study showed that the rate of in-hospital mortality in high-risk PE decreased from 2016 to 2019. ST was the most frequently used method for achieving pulmonary reperfusion in high-risk PE, whereas CDI was the most frequently used method in the entire PE cohort. In-hospital death and urgent readmissions rates remain significantly high in patients with high-risk PE.

Scoring System to Predict Hospital Outcome After Subarachnoid Hemorrhage–Incorporating Systemic Response: The CRIG Score

ObjectivesLocal and systemic proinflammatory and prothrombotic processes after aneurysmal subarachnoid hemorrhage (aSAH) precipitate delayed cerebral ischemia (DCI) and determine clinical outcome. Recent studies using admission and temporal trends of mean platelet volume to platelet count ratio (MPV:PLT) and neutrophil to lymphocyte ratio (NLR) have identified patients developing DCI. We examine if MPV:PLT and NLR along with admission clinical or radiological features can be used to develop a scoring system to predict DCI and in-hospital clinical outcome. Materials and methodsA 7-year retrospective cohort of aSAH patients admitted to a tertiary care medical center was used to study and identify clinical, radiological and laboratory parameters to predict DCI and clinical outcome (good: discharge to home or rehabilitation facility; poor: all other discharge destinations). Using regression analyses a scoring system (Clinical, Radiological, Inflammatory, dysGlycemia, CRIG) was developed. ResultsOf 271 patients, admission clinical grade (World Federation of Neurological Surgeons’ scale), radiological grade (modified Fisher score), NLR and glycated hemoglobin were identified as contributors for CRIG score. CRIGDCI score threshold of 112 and CRIGdischarge 109, respectively predicted DCI and adverse clinical outcome in score development cohort. The same threshold predicted DCI and adverse clinical outcome with 78.1 and 100% sensitivity, 44.0 and 52.2% specificity, and 63.2 and 61.4% accuracy, respectively in the score validation cohort. ConclusionsCRIG is an easily calculable scoring system that incorporates systemic response of aSAH – thus, alluding to its multisystem nature. It can be used at the time of admission to predict DCI and clinical outcome.

Decreasing Rates of Fracture-Related Hospitalization With Primary Biliary Cholangitis: Insights From the Nationwide Inpatient Sample.

IntroductionPrimary biliary cholangitis (PBC) is associated with an increased risk of developing fractures. Current guidelines recommend measures that can help prevent the development of fractures in these patients. The purpose of this study was to trend the rates of hospitalizations related to fractures and their burden on healthcare.MethodsWe performed a retrospective, cohort study of adults hospitalized in the United States with PBC between 2010 and 2014. Patients were identified using the Nationwide Inpatient Sample (NIS). Temporal analysis of PBC patients with a co-diagnosis of hip, vertebral, or wrist fractures (the study group) was performed with regards to the total number of inpatient admissions, inpatient mortality, length of stay, and total charges associated with hospitalization. Descriptive analyses were performed using the t-test for continuous data and the chi-square test for categorical data.ResultsDuring the five-year study period, there were 308,753 hospitalizations for PBC. There has been a downward trend (p=0.02) in fracture-related admissions among patients with PBC during this study period. Length of stay was higher in the PBC-fracture group (10.85 days vs 7.36 days; p<0.001). Total hospitalization charges were higher among the PBC-fracture patients when compared to the control group ($98,444 vs $72,964; p=0.004).ConclusionThere has been a gradual reduction in the rate of fracture-related hospitalizations in patients with PBC. However, patients with PBC who have fractures have increased the utilization of health care resources as compared to their cohort admitted for reasons other than for a fracture.

Impact and effectiveness of monovalent rotavirus vaccine in Tajik children

BackgroundIn 2015, Tajikistan became the second country in Central Asia to introduce rotavirus vaccine into its national immunization program. Before vaccine introduction, rotavirus was estimated to cause > 40% of pediatric diarrhea hospitalizations in Tajikistan. We aimed to assess the impact of rotavirus vaccine introduction on rotavirus disease burden and estimate rotavirus vaccine effectiveness (VE). MethodsUsing surveillance data from 2013 through 2019, we examined trends in monthly hospital admissions among children < 5 years old, before and after rotavirus vaccine introduction. Poisson regression was used to quantify decreases. VE was estimated using a test-negative case control design, with data from admissions during 2017 – 2019. Immunization records were obtained from clinics. ResultsAmong enrolled children, rotavirus positivity declined from 42% to 25% in the post-vaccine introduction period, a decrease of 41% (95% Confidence Interval [CI]: 36 – 45%). Declines were greatest in children < 12 months of age. Estimated VE of a complete course of rotavirus vaccine was 55% (95% CI: 21 – 73%) among children 5 – 59 months of age and 64% (95% CI: 36 – 80%) among children 5 – 23 months of age. VE point estimates were higher among children receiving both doses of rotavirus vaccine non-concurrently with OPV and among children receiving their first dose of rotavirus vaccine at 4 – 11 months of age, but CIs were wide and overlapping. ConclusionsOur data demonstrate that rotavirus vaccine introduction was associated with a substantial reduction in pediatric rotavirus hospitalization burden in Tajikistan, and that rotavirus vaccination is effective in Tajik children.

COVID-19: Clinical features, case fatality, and the effect of symptoms on mortality in hospitalized cases in Iran

ObjectiveIdentifying the epidemiological characteristics of COVID-19 could help to control the pandemic. The aim of this study was to characterize the epidemiological features of hospitalized COVID-19 patients in Iran. MethodsData were collected on patients admitted to a military referral hospital in Tehran, Iran, from February 8, 2020 to July 28, 2021. Sex, age, clinical symptoms, outcome, type of comorbidities, level of blood Spo2, time of admission, and time of discharge were investigated. Sex ratio, case fatality rate (CFR), and daily trends of hospital admissions and deaths were also determined. Descriptive statistics and multiple logistic regression with 95% confidence intervals were used for data analysis. The statistical significance level was set at 0.05. STATA16.0 and Excel 2010 were used for data analysis. ResultsThe median hospital length of stay (LOS) was 6 days. The following symptoms were most common: cough (63.5%), fever (50%), respiratory distress (46.1%), and muscular pain (40.8%). Hypertension (29.5%), diabetes (24.7%), and cardiovascular diseases (21.8%) were the most prevalent comorbidities. The CFR was calculated at 8.30%. Respiratory symptoms increased the odds of death by 45% (OR 1.45, 95% CI 1.03–2.06). Gastrointestinal symptoms were associated with a reduction in the mortality of COVID-19 cases, but this association was not statistically significant (OR 0.94, 95% CI 0.73–1.21). ConclusionsThe results of this study emphasize higher mortality rates among older age groups, male patients, and patients with underlying diseases.

Time trends in cancer and dementia related hospital admissions among Medicare fee-for-service population, 2013–2018

Cancer and dementia are two complicated morbidities that are commonly found in older adults and require substantial healthcare resources.[ [1] Caba Y. et al. The impact of dementia on cancer treatment decision-making, cancer treatment, and mortality: a mixed studies review. JNCI Cancer Spectr. 2021; 5: 1-18 Crossref Google Scholar , [2] McWilliams L. et al.

With the aging US population, the increasing number of older adults with these two comorbid conditions is likely to place a high demand on hospitals. Meanwhile, the shift of care delivery from inpatient to settings such as outpatient and homes, increasing reliance on family caregivers, and improved community care support may help reduce unnecessary hospitalizations.[ 3 2021 Alzheimer's disease facts and figures Alzheimers Dement. 2021; 17: 327-406 Crossref PubMed Scopus (739) Google Scholar , 4 Federman A.D. et al.

While there has been extensive research on the incidence, prevalence, and healthcare utilization among older adults with either cancer or dementia, existing literature examining older adults with both conditions is scarce and limited in scope.

To fill this gap, we examined the national and state-level trends in hospitalization rates among Medicare fee-for-service (FFS) beneficiaries with the co-presence of a major cancer (breast, prostate, lung, and colorectal) and dementia diagnoses. We hypothesized a growing trend of inpatient use among this population during the years 2013–2018. Due to the heterogeneity in cancer-specific prognosis and treatment, we also examined the trend of hospitalizations among this population by cancer types.

Trends in Substance Use Disorder-related Admissions at a Safety-net Hospital, 2008 - 2020.

Safety-net hospitals disproportionately care for people with substance use disorders (SUDs), yet little is known about trends in hospital admissions related to specific substances. This study uses electronic health record data to describe trends in substance-specific admissions at a Midwest urban safety-net hospital. We included all admissions from 2008 through 2020 and defined them as non-SUD (N = 154,477) or SUD-related (N = 63,667). We described patient characteristics and trends in substance-specific admissions. We estimated the association of SUD diagnoses with discharge against medical advice and length of stay using logistic regression and generalized linear models. Between 2008 and 2020, SUD-related admissions increased from 23.1% to 32.9% of total admissions. Admissions related to SUD had significantly more comorbidities than non-SUD-related admissions (4.7 vs 3.5, P < 0.001). Among illicit substances, cocaine-related admissions were the most common in 2008 (3.9% of total admissions, 17.2% of SUD admissions) whereas psychostimulants (eg, methamphetamines) were the most common in 2020 (7.8% of total admissions, 23.8% of SUD admissions). SUD-related hospitalizations had higher rates of against medical advice discharge (3.8%; 95% CI 3.6-3.9 vs 1.4%; 95% CI 1.3-1.4) and longer length of stay (6.3 days; 95% CI: 6.2-6.3 vs 5.3 days; 95% CI: 5.3-5.4) than non-SUD-related admissions. Over the study period, the proportion of admissions related to substance use rose to approximately one third of all admissions, driven by a rapidly increasing share of psychostimulant-related admissions. Identifying substance use patterns quickly using electronic health record data can help safety-net hospitals meet the needs of their patients and improve outcomes.
