EE564 Study on the Value Pricing of COVID-19 Vaccine in China Based on the Evidence of Cost-Effectiveness Analysis

To provide evidence for medical pricing of COVID-19 vaccination by analyzing the cost-effectiveness of different types of COVID-19 vaccines (namely, inactivated, adenovirus, recombinant protein, and mRNA vaccines) using RCT and real-world effectiveness data. Firstly, cost-effectiveness analysis of a whole inoculation of four kinds of COVID-19 vaccines was conducted, using the efficacy and effectiveness data driven from multi-center random clinical trials (RCT) or meta-analyses, while the cost data was collected from real-world. Secondly, the incremental cost-effectiveness ratio (ICER) of a whole inoculation in avoiding COVID-19 related infection, hospitalization, ICU admission, and death were calculated and compared, and then the most cost-effective vaccine was set as the comparator. Finally, prices of vaccines were adjusted to reach an equal ICER with the comparator vaccine. When medical insurance purchasing price of inactivated vaccine per dose was at 20.00 CNY, the cost of a whole inoculation should be capped at 62.34 CNY, including vaccine cost, transportation cost, storage cost and injection fee; therefore, the net price per dose of inactivated, adenovirus, recombinant protein, and mRNA vaccines were 18.80, 48.10, 9.03, and 17.51 CNY, respectively. Vaccination was cost-saving, and among them, mRNA vaccine was the most cost-saving strategy. Under the comprehensive consideration of the effects in avoiding COVID-19 related infection, hospitalization, ICU admission, and death, the prices of a whole inoculation of four kinds of vaccines should be reduced to 52.80, 48.92, 53.35, and 62.34 CNY, and the price per dose should be at 14.32, 35.49, 6.22, and 17.51 CNY, respectively. COVID-19 vaccines are cost-saving in preventing COVID-19 related infection, hospitalization, ICU admission, and avoiding death from a societal perspective, regardless of the type. Medical insurance reimbursement price of COVID-19 vaccines can be set and adjusted based on economic evaluation using RCT and real-world effectiveness evidence.

Is the incident of once chronic obstructive pulmonary disease related admission a high risk for readmission in the future?

Although it is known that a history of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is the most important predictor of future risk of AECOPD and readmission to hospitals, there is no scientific evidence that an event of only one chronic obstructive pulmonary disease (COPD)-related admission is a high risk of future readmission. We retrospectively analyzed the association of an incident of one COPD-related admission with future readmission risk. This is a retrospective study. The data of AECOPD-related admissions and readmissions during 5 years were obtained and analyzed for the admission frequencies of patients with AECOPD and an association of the admission history with a future readmission risk. The admission frequency of patients with frequent admission (3 or more admissions within 5 years) was 4.1 times that of those with non-frequent admission (0.95 vs. 0.23 times per person per year). In each calendar year during the 5-year study period, most patients (88.2%) were hospitalized only once, and 11.8% had two or more admissions. Nevertheless, their average number of admissions in each calendar year was 3.3 times that of those who only had one admission each year (3.33 vs. 1.00 times per person per year). More importantly, the positive predictive value for future readmission due to AECOPD was only 14.8% in those who had one admission in the previous year. The patients with the greater readmission risk were those with two or more admissions due to AECOPD in the previous year [crude odds ratio (OR): 4.10, 95% confidence interval (CI): 1.24-13.58 and 7.51, 95% CI: 3.81-16.68]. There is a subtype of frequent admission due to AECOPD, and it can be distinguished by having three or more admissions in the past 5 years or two or more admissions in the previous year. Nevertheless, an incident of admission once a year is not a good predictor of future readmission.

The role of peak VO2 in prognosis in patients undergoing a Cardiac Rehabilitation program

Abstract Funding Acknowledgements Type of funding sources: None. Introduction Peak oxygen uptake (peak VO2) is a strong predictor of mortality and is commonly used in the evaluation of patients for cardiac transplantation. Although guidelines suggest a peak VO2<14mL/(kg.min) as a cut-off for transplant and a peak VO2<12mL/(kg.min) in patients under beta-blockade (BB), recent data emerged, questioning the suitability of such cut-offs. Purpose To correlate CPET and echo data with outcomes after CR programs and to determine the best cut off for peak VO2 in a population with a high percentage of BB therapeutics. Methods Single center prospective study which included consecutive pts who were participating in a centre-based CR program lasting 8-12 weeks from 2019 to 2021. The CR program included initial evaluation by cardiologist and rehabilitation specialist with collection of clinical characteristics, three times weekly supervised exercise sessions, appointment with rehabilitation nurse, nutritionist and psychologist and educational sessions. Lab tests, echocardiogram and CPET were done before and after completion of the program. Multivariate analysis with Cox regression was used to correlate with events and survival was analyzed with Kaplan Meier curves. Results We analyzed 349 patients who underwent CR (82% male, mean age 60 ±11,4 years). The majority was referred for ischemic heart disease (83%) followed by valvular heart disease (7%). Mean follow-up was 36,7± 19,2 months. During FUP, 7,2% pts had CV related admissions (n=25), 4 of which were myocardial infarction. Sixteen pts died (4,6%) of which 2,3% were from cardiovascular causes. On multivariate analysis peak VO2 (HR 0.827 CI 95% 0.72-0.949, p=0.07), ejection fraction (HR 0.962 CI 95% 0.933-0.991, p=0.01) and test duration (HR 0.756 CI 95% 0.712-0.778, p=0.01) correlated with hospital admissions. Regarding mortality only peak VO2 showed statistical significance (HR 0.8 CI 95% 0.69-0.93, p=0.04). On this matter we further analyzed the best cut-off in predicting events: a peak VO2 > 14 mL/(kg.min) was a better predictor of event free-survival in these patients when comparing with a peak VO2 of 12 mL/(kg.min). Conclusions Cardiac rehabilitation has an established impact in prognosis. Echo and CPET data obtained at the beginning of the CR program can be used to identify patients who might benefit from a more closed surveillance in order to reduce risks of hospitalization. Moreover, in our population, a peak VO2 cut-off of 14mL/(kg.min) seemed to better correlate with event-free survival.

Patterns of orthopedic and trauma admissions to a tertiary teaching and referral health facility in Kenya: Chart review.

Tertiary hospitals in resource-limited countries should treat referred patients but in reality, are the first level of care for the vast majority of patients. As a result, the tertiary facility effectively functions as a primary health care facility. The urban phenomenon of widespread self-referral is associated with low rates of formal referral from peripheral health facilities. The study objective was to determine the patterns of orthopaedic and trauma admissions to Kenyatta National Hospital. This was descriptive study design. 905 patient charts were reviewed in 2021. The mean age was 33.8 years (SD 16.5) with range of 1-93 years. Majority 66.3% were between 25-64 years with those above 65 years being 40 (4.4%). Children 0-14 years comprised 10.9% of the admissions. Of the 905 admissions, 80.7% were accident and trauma-related admissions while 17.1% were non-trauma related admissions. About 50.1% were facility referrals while 49.9% were walk-ins. Majority of admissions were through Accident and Emergency Department 78.1%, Corporate Outpatient Care 14.9% and orthopedic Clinic 7.0%. About 78.7% were emergency admissions while 20.8% were elective admissions. Approximately 48.5% were due to Road Traffic Accidents and 20.9% due to falls. Close to 44.8% were casual workers and 20.2% unemployed. About 34.0% attained primary education and 35.0% secondary education. About 33.2% of female admissions were due to non-trauma conditions as compared to male admissions (12.8%) (p<0.001). Admissions for those aged 25-64 years were 3.5 more likely to have emergency admission as compared to those aged 0-14 years. Male were 65.1% less likely to have elective admissions compared to female (p<0.001). Whereas lower limb injuries and non-trauma related conditions were the most commonly admitted conditions, Lower limb injury and spine cases were mostly facility referred while non-trauma conditions were walk-in patients. Vast majority (89.2%) of admissions were from Nairobi Metropolitan region.

Vaccine effectiveness of BNT162b2 and CoronaVac against SARS-CoV-2 omicron infection and related hospital admission among people with substance use disorder in Hong Kong: a matched case-control study

People with substance use disorder have a high risk of SARS-CoV-2 infection and subsequent poor outcomes. Few studies have evaluated COVID-19 vaccine effectiveness among people with substance use disorder. We aimed to estimate the vaccine effectiveness of BNT162b2 (Fosun-BioNTech) and CoronaVac (Sinovac) against SARS-CoV-2 omicron (B.1.1.529) infection and related hospital admission in this population. We did a matched case-control study using electronic health databases in Hong Kong. Individuals diagnosed with substance use disorder between Jan 1, 2016, and Jan 1, 2022, were identified. People aged 18 years and older with SARS-CoV-2 infection from Jan 1 to May 31, 2022, and people with COVID-19-related hospital admission from Feb 16 to May 31, 2022, were included as cases and were matched by age, sex, and previous clinical history with controls from all individuals diagnosed with substance use disorder who attended the Hospital Authority health services: up to three controls for SARS-CoV-2 infection and up to ten controls for hospital admission. Conditional logistical regression was used to evaluate the association between vaccination status (ie, one, two, or three doses of BNT162b2 or CoronaVac) and the risk of SARS-CoV-2 infection and COVID-19-related hospital admission, adjusted for baseline comorbidities and medication use. Among 57 674 individuals with substance use disorder, 9523 people with SARS-CoV-2 infections (mean age 61·00 years, SD 14·90; 8075 [84·8%] males and 1448 [15·2%] females) were identified and matched to 28 217 controls (mean age 60·99 years, 14·67; 24 006 [85·1%] males and 4211 [14·9%] females), and 843 people with COVID-19-related hospital admissions (mean age 70·48 years, SD 14·68; 754 [89·4%] males and 89 [10·6%] females) were identified and matched to 7459 controls (mean age 70·24 years, 13·87; 6837 [91·7%] males and 622 [8·3%] females). Data on ethnicity were not available. We observed significant vaccine effectiveness against SARS-CoV-2 infection for two-dose BNT162b2 vaccination (20·7%, 95% CI 14·0-27·0, p<0·0001) and three-dose vaccination (all BNT162b2 41·5%, 34·4-47·8, p<0·0001; all CoronaVac 13·6%, 5·4-21·0, p=0·0015; BNT162b2 booster after two-dose CoronaVac 31·3%, 19·8-41·1, p<0·0001), but not for one dose of either vaccine or two doses of CoronaVac. Significant vaccine effectiveness against COVID-19-related hospital admission was detected after one dose of BNT162b2 vaccination (35·7%, 3·8-57·1, p=0·032), two-dose vaccination (both BNT162b2 73·3%, 64·3 to 80·0, p<0·0001; both CoronaVac 59·9%, 50·2-67·7, p<0·0001), and three-dose vaccination (all BNT162b2 86·3%, 75·6-92·3, p<0·0001; all CoronaVac 73·5% 61·0-81·9, p<0·0001; BNT162b2 booster after two-dose CoronaVac 83·7%, 64·6-92·5, p<0·0001), but not after one dose of CoronaVac. For both BNT162b2 and CoronaVac, two-dose or three-dose vaccination was protective against COVID-19-related hospital admission and the booster dose provided protection against SARS-CoV-2 infection among people with substance use disorder. Our findings confirm the importance of booster doses in this population during the period dominated by the omicron variant.

E-scooter use continues to rev up fracture diagnoses and hospital admissions compared to other modes of transportation

IntroductionThe COVID-19 pandemic was associated with an increase in popularity of e-scooter usage and a rise in e-scooter related injuries. Recent studies have elucidated trends within e-scooter injuries but there are few epidemiological studies that evaluate injury rates amongst multiple modes of transportation. This study seeks to investigate trends of e-scooter orthopedic fracture injuries compared to other traditional methods of transportation using a national database. MethodsThe National Electronic Injury Surveillance System (NEISS) database was queried between 2014 and 2020 for patients who were injured after usage of e-scooters, bicycles, or all-terrain vehicles. Primary analysis included patients with a diagnosis of fracture and utilized univariate/multivariate models to evaluate risk of hospital admission. Secondary analysis included all isolated patients to evaluate the odds of fracture development amongst modes of transportation. ResultsA total of 70,719 patients with injuries associated with e-scooter, bicycle, or all-terrain vehicle use were isolated. 15997 (22.6%) of these patients had a fracture diagnosis. Both e-scooters and all-terrain vehicles reported increased odds of fracture-related injury and direct hospitalization when compared to bicycles. E-scooter users reported a greater odds of both associated fracture (OR 1.25; 95%CI 1.03–1.51; p = 0.024) and hospital admission (OR: 2.01; 95%CI: 1.26–3.21; p = 0.003) in 2020 compared to 2014–2015. DiscussionE-scooter related orthopedic injuries and hospital admissions had the largest incidence rate increase compared to bicycle and all-terrain vehicles between 2014 and 2020. E-scooter fractures were most commonly located in the lower leg in 2014–2017, the wrist in 2018–2019, and the upper trunk in 2020. In comparison, bicycle and all-terrain vehicle fractures was most commonly shoulder and upper trunk within the study period. Further research will help to promote further understanding of the e-scooter health care burden and in prevention of these injuries. Level of evidence3.

COVID-19 enfeksiyonu geçiren bireylerde uyum bozukluğu değerlendirilmesi

Objective: This study aimed to evaluate the development of adjustment disorder according to the ADNM-20 (Adjustment Disorder New Module-20) scale in participants who were followed up for Covid-19 infection. &#x0D; &#x0D; Methods: A cross-sectional survey was conducted from September to November 2020. After sample size calculation, we aimed to reach minimum 170 people out of 1290 people who applied to the hospital for Covid-19 disease treatment. Participants were selected from the patients admitted to the hospital using a simple stratified random sampling method. We reached 182 people after treating the patients who were followed up with Covid-19 infection in a University Hospital in Istanbul, Turkey. A questionnaire and the Adjustment Disorder New Module-20 scale were applied via phone / mail at the end of the 6th month after Covid-19 related hospital admission by researchers. &#x0D; &#x0D; Results: Adjustment disorder was found in 28.8 % (n=42) of the participants disorder according to the ADNM-20 scale. While the rate of development of adjustment disorder due to Covid-19-related stress was 26.7 % (n=39); the rate of development of adjustment disorder due to non-Covid-19 stress was found to be 2.1 % (n=3). With the increase in stress load, the development of adjustment disorder increased significantly. The frequency of developing Covid-19-related stress-related adjustment disorder was statistically significantly increased with the duration of exposure to stress. &#x0D; &#x0D; Conclusion: We have found out that one out of every four people who apply to the hospital for healthcare services due to Covid-19 infection may develop an adjustment disorder. Assessment of the adjustment disorder more frequently and making early interventions may contribute to the prevention of progressive mental disorders.

COVID-19 related ICU admissions in paediatric and young adult patients in Australia: a national case series 2020–2022

COVID-19 pandemic research efforts have focused on disease phenotypes in adults. A distinct spectrum of illness has been documented in paediatric populations. We aimed to review paediatric intensive care unit (ICU) admissions in Australia, across differing variant predominant phases of the pandemic. Data reported to the Short PeRiod IncideNce sTudy of Severe Acute Respiratory Infection (SPRINT-SARI) Australia, across 49 ICUs from February 2020 to June 2022 were extracted. We defined 'child' as patients aged <12 years, 'adolescent' as patients aged 12-17 years, and 'young adult' as patients aged 18-25 years. We identified 226 paediatric ICU admissions with COVID-19, representing 3.9% of ICU admissions across the study period. Comorbidity was present in 34.6% of children, 51.4% of adolescents, and 48.7% of young adults. The need for respiratory support was highest in young adults. While 28.3% of patients <18 years required invasive ventilation, in-hospital mortality in paediatric patients was 3.6%. During the Omicron period, there was an increase in the annualised incidence of age-specific COVID-19 ICU admissions per 100,000 population, albeit a decrease in the incidence per 1000 SARS-CoV-2 notifications. This study demonstrated an appreciable burden of COVID-19 in paediatric patients. Adolescent patients presented phenotypically similar to young adults, however, illness severity was lower in younger cohorts. The Omicron phase of the pandemic demonstrated an increased age-specific population incidence of COVID-19 ICU admissions, albeit a reduced incidence when based on SARS-CoV-2 notifications.

Vitamin D as a prognostic biomarker in COVID-19: single-center study and meta-analyses

Vitamin D was investigated as a prognostic biomarker in COVID-19, in relation to both disease susceptibility and outcomes in infected individuals. Patients admitted to the hospital with a confirmed COVID-19 diagnosis were included if they had a vitamin D measurement prior to hospitalization. Using age- and sex-matched controls, vitamin D levels were investigated for an association with COVID-19 related hospitalizations. Further, vitamin D levels were investigated for an association with 30-day mortality in hospitalized COVID-19 patients. Additionally, three meta-analyses were conducted, investigating the association of vitamin D with the following outcomes: Having a positive SARS-CoV-2 test, hospitalization with COVID-19, and mortality in COVID-19 patients. A total of 685 hospitalized COVID-19 patients were included in the single-center study. Compared to controls, they had higher vitamin D levels. Unadjusted analysis of these 685 cases found higher vitamin D levels associated with increased 30-day mortality. This association disappeared after adjusting for age. In the fully adjusted model, no association between vitamin D and 30-day mortality was found. The meta-analyses found significant associations between lower vitamin D and having a positive SARS-CoV-2 test, and mortality among hospital-admitted COVID-19 patients. The relationship between lower vitamin D and COVID-19 related hospital admissions trended towards being positive but was not statistically significant. Many factors seem to influence the associations between vitamin D and COVID-19 related outcomes. Consequently, we do not believe that vitamin D in and of itself is likely to be a clinically useful and widely applicable predictor for the susceptibility and severity of COVID-19 infections.

Hospitalizations from Birth to 28 Years in a Population Cohort of Individuals Born with Five Rare Craniofacial Anomalies in Western Australia

To describe trends, age-specific patterns, and factors influencing hospitalizations for five rare craniofacial anomalies (CFA). Data on livebirths (1983-2010; n=721,019) including rare CFA (craniofacial microsomia, mandibulofacial dysostosis, Pierre Robin sequence, Van der Woude syndrome, and fronto-nasal dysplasia), episodes of death, and demographic and perinatal factors were identified from the Western Australian (WA) Register of Developmental Anomalies, Death Registrations and Midwives Notification System. Information on incident craniofacial and non-craniofacial related admissions, length of hospital stay, and intensive care and emergency related admissions were identified using principal diagnosis and procedural codes were extracted from the Hospital Morbidity Data Collection and linked to other data sources. Associations of hospitalizations by age groups as well as demographic and perinatal factors were expressed as incidence rate ratio (IRR). The incident hospitalizations were three times as high for rare CFA (IRR 3.22 - 3.72) throughout childhood into adolescence than those without. Children with rare CFA had three to four times as many potentially preventable hospitalizations until 18 years of age than those without. Specifically, respiratory infections (IRR 2.13-2.35), ear infections (IRR 7.92 - 26.28), and oral health-related conditions contributed for most non-craniofacial admissions until the adolescence period. Higher incidence of non-craniofacial related hospitalizations was observed among Indigenous children, births with intrauterine growth restrictions and families with high socioeconomic disadvantage. Throughout childhood, individuals with rare CFA had higher hospital service use, specifically for potentially preventable conditions, than those without. These population level findings can inform new preventive strategies and early disease management targeted towards reducing preventable hospitalizations.

Self-Reported Fall-Related Injury and Its Associated Factors among Adults with Visual Impairment Attending St. Paul's Hospital Millennium Medical College, Addis Ababa, Ethiopia.

Falls account for vast majority of fractures and are a significant reason for trauma related hospital admissions. The main aim of this study is to determine the prevalence of self-reported fall, related injuries, and associated factors among adult patients with visual impairment. Hospital-based cross-sectional study was conducted from July to August 2021. Systematic random sampling technique was used. The data were entered into Epi-data version 3.1 and exported to SPPS version 26 for analysis. Frequency, mean, and percentage, were used to summarize the descriptive data. The association between the outcome variable and explanatory variables was assessed using binary and multivariate logistic regressions. The adjusted odds ratio was calculated, and variables with a p-value below 0.05 at the 95% confidence interval (CI) were considered statistically significant. A total of 487 study participants were involved in this study with a response rate of 93.83%. The mean age of the study participants was 52 ± 16.26 years. The overall prevalence of self-reported fall was 36.1 %. Being female, being older than 64 years of age, rural residence, fear of falling, and blind stage of visual impairment were significantly associated with falling. The prevalence of self-reported fall was high among visually impaired individuals. Female sex, age more than 64 years, rural residence, fear of falling, and blind stage of visual impairment were significantly associated with falling. Reducing patients' chances of suffering from falling-related injuries and consequences requires raising awareness about the burden, danger, and effects of falling on persons who are visually impaired.

Migration background and COVID-19 related intensive care unit admission and mortality in the Netherlands: A cohort study.

Since the beginning of the SARS-CoV-2 pandemic, studies have been reporting inconsistently on migration background as a risk factor for COVID-19 outcomes. The aim of this study was to evaluate the association between migration background and clinical outcomes with COVID-19 in the Netherlands. This cohort study included 2,229 adult COVID-19 patients admitted in two Dutch hospitals between February 27, 2020 and March 31, 2021. Odds ratios (ORs) for hospital admission, intensive care unit (ICU) admission and mortality with 95% confidence intervals (CIs) were calculated for non-Western (Moroccan, Turkish, Surinamese or other) persons as compared with Western persons in the general population of the province of Utrecht (the Netherlands) as source population. Furthermore, among hospitalized patients, Hazard ratios (HRs) with 95% CIs for in-hospital mortality and intensive care unit (ICU) admission were calculated using Cox proportional hazard analyses. Hazard ratios were adjusted for age, sex, body mass index, hypertension, Charlson Comorbidity Index, chronic corticosteroid use before admission, income, education and population density to investigate explanatory variables. Of the 2,229 subjects, 1,707 were of Western origin and 522 were of non-Western origin. There were 313 in-hospital deaths and 503 ICU admissions. As compared with persons with a Western origin in the general population of the province of Utrecht, the ORs for non-Western persons was 1.8 (95% CI 1.7-2.0) for hospitalization, 2.1 (95% CI 1.7-2.5) for ICU admission and 1.3 (95% CI 1.0-1.7) for mortality. Among hospitalized patients, HR for ICU admission was 1.1 (95% CI 0.9-1.4) and 0.9 (95% CI 0.7-1.3) for mortality for non-Western hospitalized persons as compared with hospitalized patients of Western origin after adjustment. Non-Western persons, including Moroccan, Turkish and Surinamese subjects, had increased risks of hospital admission, ICU admission and COVID-19 related death on a population level. Among hospitalized COVID-19 patients, no association was found between migration background and ICU admission or mortality.

Patterns, trends, and factors influencing hospitalizations for craniosynostosis in Western Australia. A population-based study

Understanding hospital service use among children with a diagnosis of craniosynostosis (CS) is important to improve services and outcomes. This study aimed to describe population-level trends, patterns, and factors influencing hospitalizations for craniosynostosis in Western Australia. Data on live births (1990–2010; n = 554,624) including craniosynostosis, episodes of death, demographic, and perinatal factors were identified from the midwives, birth defects, hospitalizations, and death datasets. Information on craniosynostosis and non-craniosynostosis-related admissions, cumulative length of hospital stay (cLoS), intensive care unit, and emergency department–related admissions were extracted from the hospitalization dataset and linked to other data sources. These associations were examined using negative binomial regression presented as annual percent change and associations of hospitalizations by age groups, demographic, and perinatal factors were expressed as incidence rate ratio (IRR). We found an increasing trend in incident hospitalizations but a marginal decline in cLoS for craniosynostosis over the observed study period. Perinatal conditions, feeding difficulties, nervous system anomalies, respiratory, and other infections contributed to majority of infant non-CS-related admissions.Respiratory infections accounted for about twice the number of admissions for individuals with CS (IRRs 1.94–2.34) across all observed age groups. Higher incidence of non-CS hospitalizations was observed among females, with associated anomalies, to families with highest socioeconomic disadvantage and living in remote areas of the state. Conclusion: Marginal reduction in the cLoS for CS-related admissions observed over the 21-year period are potentially indicative of improved peri-operative care. However, higher incidence of respiratory infection-related admissions for syndromic synostosis is concerning and requires investigation.

Outcomes Associated With Early vs. Delayed Invasive Strategy in NSTEMI Complicated by High Degree AV Block: A Nationwide Analysis.

Background: High degree atrioventricular block (HDAVB) is an uncommon complication of non-ST-segment elevation myocardial infarction (NSTEMI) that frequently necessitates pacemaker implantation. This contemporary analysis compares need for pacemaker implantation based on the timing of intervention in acute NSTEMI complicated by HDAVB.Methods: We used 2016-2017 National Inpatient Sample database to identify admissions with NSTEMI and HDAVB. Time to coronary intervention from initial admission was used to segregate the admissions into two groups: early invasive strategy (EIS) (<24 hours) and delayed invasive strategy (DIS) (>24 hours). Multivariable linear and logistic regression analysis was performed to compare in-hospital outcomes among the two groups.Results: Out of 949,984 NSTEMI related admissions, coexistent HDAVB was present in 0.7% (n=6725) patients. Amongst those, 55.61% (n=3740) hospitalizations included invasive intervention (EIS=1320, DIS=2420). Patients treated with EIS were younger (69.95 years vs. 72.38 years, P<0.05) and had concomitant cardiogenic shock. Contrarily, prevalence of chronic kidney disease, heart failure, and pulmonary hypertension was higher in DIS group. EIS was associated with lower length of stay and total hospitalization cost. In-hospital mortality and pacemaker implantation rates were not significantly different between patients in the EIS and DIS groups.Conclusion: HDAVB is a rare complication of NSTEMI and often associated with right coronary artery disease. The timing of revascularization does not appear to influence the rate of pacemaker placement in NSTEMI complicated by HDAVB. Further studies are needed to assess if early invasive strategy can benefit all patients with NSTEMI and HDAVB.

Biliary colic in the emergency department: A state-wide analysis of one-year costs and clinical outcomes

ImportanceApproximately 335,000 cases of biliary colic present to US emergency departments (EDs) annually, and most patients without complications are discharged from the ED. It is unknown what are the subsequent surgery rates, subsequent complications of biliary disease, ED revisits, repeat hospitalizations and cost; and, how does the ED disposition decision (admission versus discharge) affect long-term outcomes. ObjectiveTo determine whether there is a difference in one-year surgery rates, complications of biliary disease, ED revisits, repeat hospitalizations, and cost in ED patients with uncomplicated biliary colic who are admitted to the hospital versus those that are discharged from the ED. Design, setting, and participantsA retrospective observational study was conducted using records collected from the Maryland Healthcare Cost and Utilization Project (HCUP) in the Ambulatory Surgery, the Inpatient, and the ED setting between 2016 and 2018. After applying inclusion criteria, 7036 ED patients with uncomplicated biliary colic were followed for one year after their index ED visit for repeat healthcare utilization across multiple settings. A multivariable logistic regression study was performed to asses for risk factors for surgery allocation and hospital admission. Medicare Relative Value Units (RVUs) and HCUP Cost-Charge Ratio files were used to estimate direct costs. ExposuresEpisodes of biliary colic were ascertained using ICD-10 codes at the index ED visit. Main outcomes and measuresThe primary outcome was the one-year surgery rate, defined as a cholecystectomy. Secondary outcomes included the rate of new acute cholecystitis or other related complications, ED revisits, hospital admission and costs. Associations with hospital admission and surgeries were measured using adjusted odds ratios (ORs) with 95 % CIs. ResultsOf the 7036 patients analyzed, 793 (11.3 %) were admitted and 6243 (88.7 %) were discharged on their initial ED visit. When comparing the groups who were initially admitted versus discharged, we observed similar one-year cholecystectomy rates (42 % versus 43 %, mean difference 0.5 %, 95 % CI −3.1 %–4.2 %; P < 0.001), lower rates of new cholecystitis occurrences (18 % versus 41 %, mean difference 23 %, 95 % CI, 20 %–26 %; P < 0.001), lower rates of ED revisits (96 vs 198 per 1000 patients, mean difference 102, 95 % CI, 74–130; P < 0.001) and higher costs ($9880 versus $1832, mean difference 8048, 95 % CI, 7478–8618; P < 0.001). Initial ED hospital admission was associated with increased age (adjusted odds ratio [aOR], 1.44; 95 % CI, 1.35–1.53; P < 0.001), obesity (aOR, 1.38; 95 % CI, 1.32–1.44; P < 0.001), ischemic heart disease (aOR, 1.39; 95 % CI, 1.30–1.48; P < 0.001), mood disorders (aOR, 1.18; 95 % CI, 1.13–1.24; P < 0.001), alcohol-related disorders (aOR, 1.20; 95 % CI, 1.12–1.27; P < 0.001), hyperlipidemia (aOR, 1.16; 95 % CI, 1.09–1.23; P < 0.001), hypertension (aOR, 1.15; 95 % CI, 1.08–1.21; P < 0.001), and nicotine dependence (aOR, 1.09; 95 % CI, 1.03–1.15; P = 0.003) but not associated with race (P > 0.9), ethnicity (P > 0.9), or income-stratified zip code (aOR, 1.04; 95 % CI, 0.98–1.09; P = 0.17). Conclusions and relevanceIn our analysis of ED patients with uncomplicated biliary colic from a single state, the majority of patients do not receive a cholecystectomy within one year and hospital admission at the initial visit was not associated with an overall change in rates of cholecystectomy but was associated with increased costs. These findings inform our understanding of the long-term outcomes and are important considerations when communicating care options with ED patients with biliary colic.

Combinations of medicines in patients with polypharmacy aged 65-100 in primary care: Large variability in risks of adverse drug related and emergency hospital admissions.

Polypharmacy can be a consequence of overprescribing that is prevalent in older adults with multimorbidity. Polypharmacy can cause adverse reactions and result in hospital admission. This study predicted risks of adverse drug reaction (ADR)-related and emergency hospital admissions by medicine classes. We used electronic health record data from general practices of Clinical Practice Research Datalink (CPRD GOLD) and Aurum. Older patients who received at least five medicines were included. Medicines were classified using the British National Formulary sections. Hospital admission cases were propensity-matched to controls by age, sex, and propensity for specific diseases. The matched data were used to develop and validate random forest (RF) models to predict the risk of ADR-related and emergency hospital admissions. Shapley Additive eXplanation (SHAP) values were calculated to explain the predictions. In total, 89,235 cases with polypharmacy and hospitalised with an ADR-related admission were matched to 443,497 controls. There were over 112,000 different combinations of the 50 medicine classes most implicated in ADR-related hospital admission in the RF models, with the most important medicine classes being loop diuretics, domperidone and/or metoclopramide, medicines for iron-deficiency anaemias and for hypoplastic/haemolytic/renal anaemias, and sulfonamides and/or trimethoprim. The RF models strongly predicted risks of ADR-related and emergency hospital admission. The observed Odds Ratio in the highest RF decile was 7.16 (95% CI 6.65-7.72) in the validation dataset. The C-statistics for ADR-related hospital admissions were 0.58 for age and sex and 0.66 for RF probabilities. Polypharmacy involves a very large number of different combinations of medicines, with substantial differences in risks of ADR-related and emergency hospital admissions. Although the medicines may not be causally related to increased risks, RF model predictions may be useful in prioritising medication reviews. Simple tools based on few medicine classes may not be effective in identifying high risk patients.

Clinical and biochemical determinants of length of stay, readmission and recurrence in patients admitted with diabetic ketoacidosis

Background The increasing prevalence of diabetic ketoacidosis (DKA) related admissions poses a significant burden on the healthcare systems globally. However, data regarding the predictors of healthcare resource utilization in DKA is limited and inconsistent. This study aimed to identify key predictors of hospital length of stay (LOS), readmission and recurrent DKA episodes. Methods We undertook a retrospective cross-sectional analysis of all DKA admissions from 2015 to 2021 across four hospitals in Qatar. The primary outcomes were the length of stay (LOS), 90-day readmission and 6-month and 1-year DKA recurrence. Results We included 922 patients with a median age of 35 years (25–45). 62% were males with type-1 diabetes-mellitus (T1DM) and type-2 DM (T2DM), present in 52% and 48% of patients. The median LOS was 2.6 days (IQR 1.1–4.8), and the median DKA resolution time was 18 h (10.5–29). Male-gender, new-onset DM, higher Charlson Comorbidity Index (CCI), lower haemoglobin, sodium and potassium, higher urea, longer DKA duration and MICU admission predicted a longer LOS in a multivariate regression analysis. None of the factors were significantly associated with 90-day readmission. Patients with pre-existing T1DM were more likely to have a six-month DKA recurrence than pre-existing T2DM. Patients with a 6-month DKA recurrence, female gender and T1DM had higher odds of 12-month recurrence, whereas a consult with a diabetes educator at the index admission was associated with decreased odds of recurrence. Conclusions/interpretation This is the most extensive study from the Middle-East region reporting on LOS, readmissions and the recurrence of DKA. Results from this study with a diverse population may be valuable for physicians and healthcare systems to decrease the diabetes-related healthcare burden in DKA patients.

Therapeutic potential of IL6R blockade for the treatment of sepsis and sepsis-related death: A Mendelian randomisation study.

Sepsis is characterised by dysregulated, life-threatening immune responses, which are thought to be driven by cytokines such as interleukin 6 (IL-6). Genetic variants in IL6R known to down-regulate IL-6 signalling are associated with improved Coronavirus Disease 2019 (COVID-19) outcomes, a finding later confirmed in randomised trials of IL-6 receptor antagonists (IL6RAs). We hypothesised that blockade of IL6R could also improve outcomes in sepsis. We performed a Mendelian randomisation (MR) analysis using single nucleotide polymorphisms (SNPs) in and near IL6R to evaluate the likely causal effects of IL6R blockade on sepsis (primary outcome), sepsis severity, other infections, and COVID-19 (secondary outcomes). We weighted SNPs by their effect on CRP and combined results across them in inverse variance weighted meta-analysis, proxying the effect of IL6RA. Our outcomes were measured in UK Biobank, FinnGen, the COVID-19 Host Genetics Initiative (HGI), and the GenOSept and GainS consortium. We performed several sensitivity analyses to test assumptions of our methods, including utilising variants around CRP and gp130 in a similar analysis. In the UK Biobank cohort (N = 486,484, including 11,643 with sepsis), IL6R blockade was associated with a decreased risk of our primary outcome, sepsis (odds ratio (OR) = 0.80; 95% confidence interval (CI) 0.66 to 0.96, per unit of natural log-transformed CRP decrease). The size of this effect increased with severity, with larger effects on 28-day sepsis mortality (OR = 0.74; 95% CI 0.47 to 1.15); critical care admission with sepsis (OR = 0.48, 95% CI 0.30 to 0.78) and critical care death with sepsis (OR = 0.37, 95% CI 0.14 to 0.98). Similar associations were seen with severe respiratory infection: OR for pneumonia in critical care 0.69 (95% CI 0.49 to 0.97) and for sepsis survival in critical care (OR = 0.22; 95% CI 0.04 to 1.31) in the GainS and GenOSept consortium, although this result had a large degree of imprecision. We also confirm the previously reported protective effect of IL6R blockade on severe COVID-19 (OR = 0.69, 95% CI 0.57 to 0.84) in the COVID-19 HGI, which was of similar magnitude to that seen in sepsis. Sensitivity analyses did not alter our primary results. These results are subject to the limitations and assumptions of MR, which in this case reflects interpretation of these SNP effects as causally acting through blockade of IL6R, and reflect lifetime exposure to IL6R blockade, rather than the effect of therapeutic IL6R blockade. IL6R blockade is causally associated with reduced incidence of sepsis. Similar but imprecisely estimated results supported a causal effect also on sepsis related mortality and critical care admission with sepsis. These effects are comparable in size to the effect seen in severe COVID-19, where IL-6 receptor antagonists were shown to improve survival. These data suggest that a randomised trial of IL-6 receptor antagonists in sepsis should be considered.
