The feasibility, acceptability and appropriateness of screening for frailty in Australians aged 75 years and over attending Australian general practice

Background Globally, frailty is associated with a high prevalence of avoidable hospital admissions and emergency department visits, with substantial associated healthcare and personal costs. International guidelines recommend incorporation of frailty identification and care planning into routine primary care workflow to support patients who may be identified as pre-frail/frail. Our study aimed to: (1) determine the feasibility, acceptability, appropriateness and determinants of implementing a validated FRAIL Scale screening Tool into general practices in two disparate Australian regions (Sydney North and Brisbane South); and (2) map the resources and referral options required to support frailty management and potential reversal. Methods Using the FRAIL Scale Tool, practices screened eligible patients (aged ≥75 years) for risk of frailty and referred to associated management options. The percentage of patients identified as frail/pre-frail, and management options and referrals made by practice staff for those identified as frail/pre-frail were recorded. Semi-structured qualitative interviews were conducted with practice staff to understand the feasibility, acceptability, appropriateness and determinants of implementing the Tool. Results The Tool was implemented by 19 general practices in two Primary Health Networks and 1071 consenting patients were assessed. Overall, 80% of patients (n = 860) met the criterion for frailty: 33% of patients (n = 352) were frail, and 47% were pre-frail (n = 508). They were predominantly then referred for exercise prescription, medication reviews and geriatric assessment. The Tool was acceptable to staff and patients and compatible with practice workflows. Conclusions This study demonstrates that frailty is identified frequently in Australians aged ≥75 years who visit their general practice. It’s identification, linked with management support to reverse or reduce frailty risk, can be readily incorporated into the Medicare-funded annual 75+ Health Assessment.

Socioeconomic factors including patient income, education level and health insurance influence post-operative secondary surgery and hospitalization rates following hip arthroscopy

To evaluate a large cross-sectional sample of patients utilizing administrative database records, and analyze the effects of income, insurance type, and education level on outcomes after hip arthroscopy, including 2-year revision surgery, conversion to total hip arthroplasty (THA) and 90-day hospitalizations. Current Procedural Terminology codes were used to query the PearlDiverTM Mariner database from October 2015 to January 2020 for patients undergoing hip arthroscopy with minimum 2-year follow-up. Patients were categorized by mean family income in their zip code of residence (MFIR), health insurance type, and educational attainment in their zip code of residence (EAR). 2-year revision arthroscopy, conversion to THA and 90-day hospital readmissions or emergency department (ED) visits were analyzed along socioeconomic strata. Multivariate analysis of 33,326 patients revealed that patients with MFIR between $30,000-$70,000 had lower odds of 2-year revision arthroscopy [OR = 0.63, p < 0.001], THA conversion [OR= 0.76, p= 0.050], and 90-day readmission [OR= 0.53, p= 0.007] compared to MFIR >$100,000. Compared to patients with commercial insurance, patients with Medicare had lower odds of revision arthroscopy [OR= 0.60, p= 0.035] and THA conversion [OR= 0.46, p< 0.001], but greater odds of 90-day readmission [OR= 1.74, p= 0.007]. Patients with Medicaid had higher odds of 90-day ED visits [OR= 1.84, p< 0.001]. Patients with low EAR had higher odds of revision arthroscopy [OR= 1.42, p= 0.005] and THA conversion [OR= 1.58, p= 0.002] compared to those with high EAR. Following hip arthroscopy, patients residing in areas with lower mean family income were less likely to undergo reoperations and readmissions. Medicare patients showed lower reoperation but higher readmission odds, while Medicaid patients showed higher odds of ED visits. Additionally, higher educational attainment in the zip code of residence is protective against future reoperation. Level III. Retrospective Case Series.

EAACI guidelines on environmental science for allergy and asthma: The impact of short-term exposure to outdoor air pollutants on asthma-related outcomes and recommendations for mitigation measures.

The EAACI Guidelines on the impact of short-term exposure to outdoor pollutants on asthma-related outcomes provide recommendations for prevention, patient care and mitigation in a framework supporting rational decisions for healthcare professionals and patients to individualize and improve asthma management and for policymakers and regulators as an evidence-informed reference to help setting legally binding standards and goals for outdoor air quality at international, national and local levels. The Guideline was developed using the GRADE approach and evaluated outdoor pollutants referenced in the current Air Quality Guideline of the World Health Organization as single or mixed pollutants and outdoor pesticides. Short-term exposure to all pollutants evaluated increases the risk of asthma-related adverse outcomes, especially hospital admissions and emergency department visits (moderate certainty of evidence at specific lag days). There is limited evidence for the impact of traffic-related air pollution and outdoor pesticides exposure as well as for the interventions to reduce emissions. Due to the quality of evidence, conditional recommendations were formulated for all pollutants and for the interventions reducing outdoor air pollution. Asthma management counselled by the current EAACI guidelines can improve asthma-related outcomes but global measures for clean air are needed to achieve significant impact.

Impact of dementia on 30-, 180-, and 365-day mortality during the first pandemic wave in older adults seen in spanish emergency departments diagnosed with or without COVID-19

Objectives To assess whether dementia is an independent predictor of death after a hospital emergency department (ED) visit by older adults with or without a COVID-19 diagnosis during the first pandemic wave. Method We used data from the EDEN-Covid (Emergency Department and Elderly Needs during Covid) cohort formed by all patients ≥65 years seen in 52 Spanish EDs from March 30 to April 5, 2020. The association of prior history of dementia with mortality at 30, 180 and 365 d was evaluated in the overall sample and according to a COVID-19 or non COVID diagnosis. Results We included 9,770 patients aged 78.7 ± 8.3 years, 51.1% men, 1513 (15.5%) subjects with prior history of dementia and 3055 (31.3%) with COVID-19 diagnosis. 1399 patients (14.3%) died at 30 d, 2008 (20.6%) at 180 days and 2456 (25.1%) at 365 d. The adjusted Hazard Ratio (aHR) for age, sex, comorbidity, disability and diagnosis for death associated with dementia were 1.16 (95% CI 1.01–1.34) at 30 d; 1.15 at 180 d (95% CI 1.03–1.30) and 1.19 at 365 d (95% CI 1.07–1.32), p < .001. In patients with COVID-19, the aHR were 1.26 (95% CI: 1.04–1.52) at 30 days; 1.29 at 180 d (95% CI: 1.09–1.53) and 1.35 at 365 d (95% CI: 1.15–1.58). Conclusion Dementia in older adults attending Spanish EDs during the first pandemic wave was independently associated with 30-, 180- and 365-day mortality. This impact was lower when adjusted for age, sex, comorbidity and disability, and was greater in patients diagnosed with COVID-19.

Nonspecific Effects of the Bacillus Calmette-Guérin Vaccine in Portuguese Children Under 5 Years of Age: Protocol for a Population-Based Historical Birth Cohort Study.

The Bacillus Calmette-Guérin vaccine (BCG) against tuberculosis (TB) shows beneficial nonspecific effects, which are likely related to innate immune training. Until 2016, a single BCG dose was administered to all newborns in Portugal. In July 2016, a clinical guideline established that only children under 6 years belonging to high-risk groups should receive BCG. This might have prevented nonvaccinated children from developing trained immunological responses as effectively as BCG-vaccinated children. This study aims to investigate if there is variation in TB-related and all-cause mortality, and severe, moderate, or mild morbidity in children under 5 years of age, and whether such variation might be explained by the BCG vaccination policy change in 2016. This population-based historical birth cohort study includes children under 5 years of age born in Portugal between July 1, 2010, and June 30, 2021. Newborns with low birth weight, premature status, or known or suspected HIV infection are excluded. The follow-up period is until the completion of 5 years of age or the end of follow-up (June 30, 2021). The study will use secondary data from the National Health Service user registry, death certificate database, vaccination registry, communicable diseases surveillance system, TB surveillance system, diagnosis-related group information system for hospital admissions and emergency department visits, and primary health care information system. The data will be linked. Primary outcomes include person-time incidence rates of death (all causes and TB), TB diagnosis, and all causes and some specific causes of severe, moderate, or mild morbidity, and the incidence rate ratio of nonvaccinated to BCG-vaccinated children. We will compare the probability of surviving the first and fifth years of life or of not having severe, moderate, or mild morbidity during the follow-up period according to exposure (BCG vaccinated or nonvaccinated, number of doses, and time from birth until the first dose), using the log-rank test for assessing differences in survival rates between exposed and nonexposed children and hazard ratios for quantifying the differences. Moreover, we will perform a proportional hazards regression analysis. Ethics approval has been obtained. In March 2022, database owners were contacted to present the project and discuss the request for data. A unique identifier will be used. In July 2023, a process of redefinition of the variables per database was initiated. Data were received in October and November 2023. In November 2023, further work was conducted. By April 2024, we expect to start analyzing the full data set. The results will contribute to the accumulating body of knowledge and might have relevance to guide global BCG vaccination policy. Data linkage can contribute to a swifter mechanism to use available health data to conduct population-based studies and inform policy decision-making.

Patient activation in advanced chronic kidney disease: a cross-sectional study

BackgroundPatient activation refers to the knowledge, confidence and skills required for the management of chronic disease and is antecedent to self-management. Greater self-management in chronic kidney disease (CKD) results in improved patient experience and patient outcomes.AimTo examine patient activation levels in people with CKD stage 5 pre-dialysis and determine associations with sociodemographic characteristics, treatment adherence and healthcare utilisation.Methods/designPeople with CKD stage 5 not receiving dialysis from one Australian kidney care service. Patient activation was measured using the 13-item Patient Activation Measure (PAM-13). Sociodemographic and clinical outcome data (emergency department visits, admissions) were collected from medical records. Morisky Medication Adherence Scale was used to determine self-report medication adherence.ResultsTwo hundred and four participants completed the study. The mean PAM-13 score was 53.4 (SD 13.8), with 73% reporting low activation levels (1 and 2). Patient activation scores significantly decreased with increased age (P < 0.001) and significantly increased with higher educational levels (P < 0.001). Higher patient activation level was associated with fewer hospital emergency department visits (P = 0.03) and increased medication adherence (P < 0.001).ConclusionPatient activation levels are low in people with CKD stage 5 not receiving dialysis suggesting limited ability for self-management and capacity for optimally informed decisions about their healthcare. Efforts to improve patient activation need to consider age and education level.Graphical abstract

The impact of outdoor pollution and extreme temperatures on asthma-related outcomes: A systematic review for the EAACI guidelines on environmental science for allergic diseases and asthma.

Air pollution is one of the biggest environmental threats for asthma. Its impact is augmented by climate change. To inform the recommendations of the EAACI Guidelines on the environmental science for allergic diseases and asthma, a systematic review (SR) evaluated the impact on asthma-related outcomes of short-term exposure to outdoor air pollutants (PM2.5, PM10, NO2 , SO2 , O3 , and CO), heavy traffic, outdoor pesticides, and extreme temperatures. Additionally, the SR evaluated the impact of the efficacy of interventions reducing outdoor pollutants. The risk of bias was assessed using ROBINS-E tools and the certainty of the evidence by using GRADE. Short-term exposure to PM2.5, PM10, and NO2 probably increases the risk of asthma-related hospital admissions (HA) and emergency department (ED) visits (moderate certainty evidence). Exposure to heavy traffic may increase HA and deteriorate asthma control (low certainty evidence). Interventions reducing outdoor pollutants may reduce asthma exacerbations (low to very low certainty evidence). Exposure to fumigants may increase the risk of new-onset asthma in agricultural workers, while exposure to 1,3-dichloropropene may increase the risk of asthma-related ED visits (low certainty evidence). Heatwaves and cold spells may increase the risk of asthma-related ED visits and HA and asthma mortality (low certainty evidence).

Evaluation of pharmacist-led transition of care program in patients with acute coronary syndrome

BackgroundGuideline-directed medical therapies (GDMTs), initiated in-hospital and continued during the transition to outpatient care, are paramount to successful outcomes for patients with acute coronary syndrome (ACS). Incomplete discharge medication prescribing and delayed follow-up lead to worse cardiovascular outcomes. ObjectivesWe investigated a system of care using inpatient and outpatient clinical pharmacists to close GDMT gaps, ensure seamless transition to outpatient care, improve patient education, and optimize therapies. MethodsWe conducted a pre-post cohort analysis of patients with ACS pre- versus post-intervention to compare process metrics and key outcomes using electronic health record data. ResultsThere were 181 and 135 patients in the pre- and post-intervention cohorts, respectively. Patients post-intervention were significantly more likely to have appropriately-timed follow-up visits scheduled with cardiology (79% vs. 51%, P < 0.0001) and primary care (57% vs. 43%, P = 0.01), to be discharged with prescriptions for P2Y12 inhibitors (87% vs. 64%, P < 0.0001), high dose statins (86% vs. 70%, P = 0.001), and beta blockers (87% vs. 76%, P = 0.01), and significantly less likely to have 30-day all-cause hospital readmissions (4% vs. 12%, P = 0.02) and emergency department (ED) visits (10% vs. 18%, P = 0.04). ConclusionsThe integration of advanced practicing pharmacists into a cardiology team at transition and post-hospitalization resulted in improved rates of posthospital follow-up visits, optimization of GDMT medications, and significantly lower 30-day hospital readmission and ED utilization.

Medication-Related Hospital Admissions and Emergency Department Visits in Older People with Diabetes: A Systematic Review.

Limited data are available regarding adverse drug reactions (ADRs) and medication-related hospitalisations or emergency department (ED) visits in older adults with diabetes, especially since the emergence of newer antidiabetic agents. This systematic review aimed to explore the nature of hospital admissions and ED visits that are medication-related in older adults with diabetes. The review was conducted according to the PRISMA guidelines. Studies in English that reported on older adults (mean age ≥ 60 years) with diabetes admitted to the hospital or presenting to ED due to medication-related problems and published between January 2000 and October 2023 were identified using Medline, Embase, and International Pharmaceutical Abstracts databases. Thirty-five studies were included. Medication-related hospital admissions and ED visits were all reported as episodes of hypoglycaemia and were most frequently associated with insulins and sulfonylureas. The studies indicated a decline in hypoglycaemia-related hospitalisations or ED presentations in older adults with diabetes since 2015. However, the associated medications remain the same. This finding suggests that older patients on insulin or secretagogue agents should be closely monitored to prevent potential adverse events, and newer agents should be used whenever clinically appropriate.

Clinical and Socioeconomic Associations With Hospital Days and Emergency Department Visits Among Medically Complex Children: A Retrospective Cohort Study.

To estimate associations between clinical and socioeconomic variables and hospital days and emergency department (ED) visits for children with medical complexity (CMCs) for 5 years after index admission. Retrospective, longitudinal, population-based cohort study of CMCs in Alberta (n = 12 621) diagnosed between 2010 and 2013 using administrative data linked to socioeconomic data. The primary outcomes were annual cumulative numbers of hospital days and ED visits for 5 years after index admission. Data were analyzed using mixed-effect hurdle regression. Among CMCs utilizing resources, those with more chronic medications had more hospital days (relative difference [RD] 3.331 for ≥5 vs 0 medications in year 1, SE 0.347, P value < .001) and ED visits (RD 1.836 for 0 vs ≥5 medications in year 1, SE 0.133, P value < .001). Among these CMCs, initial length of stay had significant, positive associations with hospital days (RD 1.960-5.097, SE 0.161-0.610, P value < .001 outside of the gastrointestinal and hematology and immunodeficiency groups). Those residing in rural or remote areas had more ED visits than those in urban or metropolitan locations (RD 1.727 for rural versus urban, SE 0.075, P < .001). Material and social deprivation had significant, positive associations with number of ED visits. Clinical factors are more strongly associated with hospitalizations and socioeconomic factors with ED visits. Policy administrators and researchers aiming to optimize resource use and improve outcomes for CMCs should consider interventions that include both clinical care and socioeconomic support.

Severe Acute Exacerbations of Chronic Obstructive Pulmonary Disease: Are There Significant Differences Between Hospitalized and Emergency Department Patients?

Current guidelines define a severe acute exacerbation of chronic obstructive pulmonary disease (AECOPD) as an increase in symptoms requiring hospital admission or emergency department (ED) visit. Little is known about whether or not subjects requiring hospitalization and those needing only ED care have similar patient profiles and if their clinical outcomes appear comparable. The main goals of this study were to compare the demographic and clinical characteristics of patients treated for an AECOPD with an inpatient admission versus an ED visit and to review if hospital resource utilization was different between the 2 groups after discharge. Subjects treated in 2022 at Montfort Hospital for an AECOPD were reviewed. Patient demographic information was collected in addition to spirometry results and blood eosinophil counts on file. Supplemental oxygen use and medication lists were also recorded. Patients with an initial hospital admission were compared to those requiring only ED care with univariate and multivariate analyses. We also assessed if subjects were again treated for an AECOPD up to 6 months post initial discharge, and if so, the type of hospital visits (hospitalization or ED). A total of 135 individuals necessitated hospitalization and 79 received ED care for the treatment of an AECOPD. On univariate analysis, patients requiring an inpatient stay appeared older and were more likely to have spirometry results on file. A greater proportion of hospitalized individuals were on supplemental oxygen and prescribed at least one long-acting inhaled medication. These studied variables remained significant after multivariate logistic regression analysis. Subjects with an initial inpatient admission were also more likely to require hospitalization upon repeat presentation for a severe AECOPD. Given the important differences observed in both patient characteristics and hospital resource utilization, this study supports considering an AECOPD requiring inpatient admission versus an ED visit as distinct categories of events.

Antibiotics for Suspected Urinary Tract Infections in the Emergency Department, How Are We Doing?

Background: Urinary tract infection (UTI) is a major public health issue that affects millions of people each year, and a common reason for hospital admission and Emergency Department (ED) visits. ED is a common yet crucial setting for antibiotic prescription. Unfortunately, antibiotic therapies that are unnecessarily prescribed continue to contribute to the global issue of bacterial resistance. Our study aims to determine the prevalence and reasons for inappropriate antibiotic use for UTI in the ED, to highlight the most commonly prescribed antibiotic, and to define the most sensitive antibiotic and most common pathogen based on urine cultures. Methods: A retrospective cohort review conducted at King Fahad University Hospital in Al Khobar, eastern province of Saudi Arabia. Data was collected during the duration of 2017 – 2022 from electrical medical records for all patients who had a urinalysis and urine culture in the ED and were managed as outpatients. Antibiotic prescription was considered Inappropriate if: Asymptomatic patient, Negative urinalysis, Negative or contaminated urine culture or Prescribed antibiotic did not demonstrate sensitivity to the tested bacteria. R-Jamovi software (version 2.3, 2022) was used for analysis. Results: The total sample included 2531 patients. 70.4 % (n= 1781) were females. The most common age group was adults (from 15- 63 years old. Dysuria was the most reported symptom, representing 28.3 % (n = 606). Only ~ 21% of the prescribed antibiotics were appropriate (P&amp;lt; 0.001). The most common reason for inappropriateness was that the tested antibiotic was not sensitive to growth. Ciprofloxacin was the most commonly prescribed antibiotic, representing 34.8%. E. coli was the most common pathogen causing UTI, representing 37.5%. Gentamicin was the most sensitive antibiotic among the urine culture results, representing 90% (P

RANDOMIZED CONTROLLED TRIAL OF LAY-DELIVERED INTERVENTION FOR OLDER ADULTS DISCHARGED FROM THE HOSPITAL

Abstract The second speaker will describe the background, aims, methods, and progress of a PCORI-funded RCT to reduce rehospitalization for Black/African American and Hispanic/Latino older adults after medical hospitalization. Across three regional hospitals, 402 older adults living with chronic illness (e.g., cardiovascular disease, diabetes, hypertension etc.,) will be enrolled while inpatient at one of our three partnering hospitals and randomized to receive one of three interventions in this comparative effectiveness trial: (1) the evidence-based Care Transitions Intervention (CTI), (2) CTI plus a peer educator intervention (CTI+Peer), or (3) usual care. Participants are assessed at 4 timepoints (baseline, 30 days, 90 days and 6 months) to examine differences in the primary outcomes of 30-day all cause hospital readmissions and emergency department visits. Secondary outcomes including quality of life, self-efficacy managing chronic disease, functioning, perceived social support and mortality. CTI Coaches and Peer educators participate in rigorous trainings which includes both didactic and interactive components to ensure interventionists are able to deliver the intervention with fidelity to the models. After training, CTI Coaches and Peer Educators participate in regular supervision meetings. They receive weekly virtual supervision check-ins from USF study staff and participate in a monthly group-based supervision in person. This trial involves close collaboration with leaders and coordinators at each hospital and an Area Agency on Aging (AAA) for recruitment, engagement of study interventionists and study dissemination. Across sites, 18 CTI Coaches and 11 Peer Educators have been trained and certified, and 145 participants have been enrolled (as of 3/8/2023).

Patient- and family-centred care transition interventions for adults: a systematic review and meta-analysis of RCTs.

Although patient centredness is part of providing high-quality health care, little is known about the effectiveness of care transition interventions that involve patients and their families on readmissions to the hospital or emergency visits post-discharge. This systematic review (SR) aimed to examine the evidence on patient- and family-centred (PFC) care transition interventions and evaluate their effectiveness on adults' hospital readmissions and emergency department (ED) visits after discharge. Searches of Medline, CINAHL, and Embase databases were conducted from the earliest available online year of indexing up to and including 14 March 2021. The studies included: (i) were about care transitions (hospital to home) of ≥18-year-old patients; (ii) had components of patient-centred care and care transition frameworks; (iii) reported on one or more outcomes were among hospital readmissions and ED visits after discharge; and (iv) were cluster-, pilot- or randomized-controlled trials published in English or French. Study selection, data extraction, and risk of bias assessment were completed by two independent reviewers. A narrative synthesis was performed, and pooled odd ratios, standardized mean differences, and mean differences were calculated using a random-effects meta-analysis. Of the 10,021 citations screened, 50 trials were included in the SR and 44 were included in the meta-analyses. Care transition intervention types included health assessment, symptom and disease management, medication reconciliation, discharge planning, risk management, complication detection, and emotional support. Results showed that PFC care transition interventions significantly reduced the risk of hospital readmission rates compared to usual care [incident rate ratio (IRR), 0.86; 95% confidence interval (CI), 0.75-0.98; I2 = 73%] regardless of time elapsed since discharge. However, these same interventions had minimal impact on the risk of ED visit rates compared to usual care group regardless of time passed after discharge (IRR, 1.00; 95% CI, 0.85-1.18; I2 = 29%). PFC care transition interventions containing a greater number of patient-centred care (IRR, 0.73; 95% CI, 0.57-0.94; I2 = 59%) and care transition components (IRR, 0.76; 95% CI, 0.64-0.91; I2 = 4%) significantly decreased the risk of patients being readmitted. However, these interventions did not significantly increase the risk of patients visiting the ED after discharge (IRR, 1.54; CI 95%, 0.91-2.61). Future interventions should focus on patients' and families' values, beliefs, needs, preferences, race, age, gender, and social determinants of health to improve the quality of adults' care transitions.

Impact of Clinical Pharmacists-driven Bundled Activities from Admission to Discharge on 90-day Hospital Readmissions and Emergency Department Visits.

Patient-centered clinical pharmacists' activities play a major role in improving clinical outcomes by optimizing the efficacy of drug therapies and minimizing associated toxicities during hospitalization, at the transition of care, and upon discharge. We aimed to compare the impact of comprehensive versus partial clinical pharmacists-driven bundled of care services on the rate of 90-day hospital readmissions and emergency department (ED) visits. This retrospective study included all admitted patients who received a comprehensive or partial bundle of clinical pharmacy services (medication history, interventions, counseling, and discharge prescription review) from 1 January 2021 to 30 June 2021 at Sultan Qaboos University Hospital. The comprehensive bundle of care included the four services, while the partial bundle of care included one, two, or three services only. Analyses were performed using univariate and multivariate statistical techniques. The study included 430 patients with a mean age of 56.021.0 years, and 43.7% (n = 188) were male. Of the patients, 12.1% (n = 52) received a comprehensive bundle of care. Compared with the partial bundle of care group, the comprehensive bundle of care group had significantly more patients with diabetes (65.4% vs. 42.9%; p =0.002), % 3 comorbidities (50.0% vs. 29.4%; p =0.003), and polypharmacy (% 5 medications) (73.1% vs. 46.0%; p < 0.001). The comprehensive bundle of care group was significantly associated with a lower 90-day readmission rate (adjusted odds ratio (aOR) = 0.27, 95% CI: 0.90?"0.82; p =0.021) but not with ED visits (aOR = 0.57, 95% CI: 0.13?"2.57; p =0.461). This study demonstrated a significant reduction in the 90-day readmission rate for patients on a comprehensive bundle of care but not ED visits. These findings emphasize the importance of the comprehensive services provided by clinical pharmacists on the healthcare resources use and clinical outcomes.

Effectiveness of BNT162b2 BA.4/5 bivalent mRNA vaccine against a range of COVID-19 outcomes in a large health system in the USA: a test-negative case–control study

XBB-related omicron sublineages have recently replaced BA.4/5 as the predominant omicron sublineages in the USA and other regions globally. Despite preliminary signs of immune evasion of XBB sublineages, few data exist describing the real-world effectiveness of bivalent COVID-19 vaccines, especially against XBB-related illness. We aimed to investigate the effectiveness of the Pfizer--BioNTech BNT162b2 BA.4/5 bivalent vaccine against both BA.4/5-related and XBB-related disease in adults aged 18 years or older. In this test-negative case-control study, we estimated the effectiveness of the BNT162b2 BA.4/5 bivalent vaccine using data from electronic health records of Kaiser Permanente Southern California health system members aged 18 years or older who received at least two doses of the wild-type COVID-19 mRNA vaccines. Participants sought care for acute respiratory infection between Aug 31, 2022, and April 15, 2023, and were tested for SARS-CoV-2 via PCR tests. Relative vaccine effectiveness (≥2 doses of wild-type mRNA vaccine plus a BNT162b2 BA.4/5 bivalent booster vs ≥2 doses of a wild-type mRNA vaccine alone) and absolute vaccine effectiveness (vs unvaccinated individuals) was estimated against critical illness related to acute respiratory infection (intensive care unit [ICU] admission, mechanical ventilation, or inpatient death), hospital admission, emergency department or urgent care visits, and in-person outpatient encounters with odds ratios from logistic regression models adjusted for demographic and clinical factors. We stratified vaccine effectiveness estimates for hospital admission, emergency department or urgent care visits, and outpatient encounters by omicron sublineage (ie, likely BA.4/5-related vs likely XBB-related), time since bivalent booster receipt, age group, number of wild-type doses received, and immunocompromised status. This study is registered with ClinicalTrials.gov (NCT04848584). Analyses were conducted for 123 419 encounters (24 246 COVID-19 cases and 99 173 test-negative controls), including 4131 episode of critical illness (a subset of hospital admissions), 14 529 hospital admissions, 63 566 emergency department or urgent care visits, and 45 324 outpatient visits. 20 555 infections were BA.4/5 related and 3691 were XBB related. In adjusted analyses, relative vaccine effectiveness for those who received the BNT162b2 BA.4/5 bivalent booster compared with those who received at least two doses of a wild-type mRNA vaccine alone was an additional 50% (95% CI 23-68) against critical illness, an additional 39% (28-49) against hospital admission, an additional 35% (30-40) against emergency department or urgent care visits, and an additional 28% (22-33) against outpatient encounters. Waning of the bivalent booster from 0-3 months to 4-7 months after vaccination was evident for outpatient outcomes but was not detected for critical illness, hospital admission, and emergency department or urgent care outcomes. The relative effectiveness of the BNT162b2 BA.4/5 bivalent booster for XBB-related infections compared with BA.4/5-related infections was 56% (95% CI 12-78) versus 40% (27-50) for hospital admission; 34% (21-45) versus 36% (30-41) against emergency department or urgent care visits; and 29% (19-38) versus 27% (20-33) for outpatient encounters. By mid-April, 2023, individuals previously vaccinated only with wild-type vaccines had little protection against COVID-19-including hospital admission. A BNT162b2 BA.4/5 bivalent booster restored protection against a range of COVID-19 outcomes, including against XBB-related sublineages, with the most substantial protection observed against hospital admission and critical illness.

Reduced Asthma Exacerbations in Adult Patients Treated With Bronchial Thermoplasty.

Bronchial thermoplasty (BT) has been shown to be effective in randomized controlled trials of patients with severe asthma who failed to achieve disease control with high-dose inhaled corticosteroids combined with bronchodilators. However, the effectiveness of BT in real-world clinical settings, especially among the Asian population, has not been determined. To evaluate the effectiveness of BT using a nationwide database. Using the inpatient and outpatient data from the Japanese Diagnosis Procedure Combination database, we applied a self-controlled case series design to evaluate changes in the composite outcome of hospital admissions and emergency department visits, as well as systemic corticosteroid dose, between 1 year before and after BT. We also conducted subgroup analyses based on patients' profiles. Among the 561 patients with asthma who underwent BT treatment between September 2014 and March 2020, 102 patients with at least 1 outcome were analyzed. Bronchial thermoplasty was significantly associated with an improvement in the composite outcome of hospital admission and emergency department visits (incidence rate ratio 0.53; 95% CI 0.44-0.64). Systemic corticosteroid use was reduced after BT sessions (1931.5 mg [1,341.2-3,725.3 mg] to 641.3 mg [134.2-1,691.1 mg] per person-year; P < .001). Although all groups showed a significant improvement in the composite outcome in the subgroup analyses, BT tended to be less effective among people older than 65 years and those with higher body mass index (>25 kg/m2). The present study using real-world data suggests that BT may improve asthma control; however, the effectiveness of BT can vary depending on patient baseline profiles.

Evaluation of negative binomial and zero-inflated negative binomial models for the analysis of zero-inflated count data: application to the telemedicine for children with medical complexity trial

BackgroundTwo characteristics of commonly used outcomes in medical research are zero inflation and non-negative integers; examples include the number of hospital admissions or emergency department visits, where the majority of patients will have zero counts. Zero-inflated regression models were devised to analyze this type of data. However, the performance of zero-inflated regression models or the properties of data best suited for these analyses have not been thoroughly investigated.MethodsWe conducted a simulation study to evaluate the performance of two generalized linear models, negative binomial and zero-inflated negative binomial, for analyzing zero-inflated count data. Simulation scenarios assumed a randomized controlled trial design and varied the true underlying distribution, sample size, and rate of zero inflation. We compared the models in terms of bias, mean squared error, and coverage. Additionally, we used logistic regression to determine which data properties are most important for predicting the best-fitting model.ResultsWe first found that, regardless of the rate of zero inflation, there was little difference between the conventional negative binomial and its zero-inflated counterpart in terms of bias of the marginal treatment group coefficient. Second, even when the outcome was simulated from a zero-inflated distribution, a negative binomial model was favored above its ZI counterpart in terms of the Akaike Information Criterion. Third, the mean and skewness of the non-zero part of the data were stronger predictors of model preference than the percentage of zero counts. These results were not affected by the sample size, which ranged from 60 to 800.ConclusionsWe recommend that the rate of zero inflation and overdispersion in the outcome should not be the sole and main justification for choosing zero-inflated regression models. Investigators should also consider other data characteristics when choosing a model for count data. In addition, if the performance of the NB and ZINB regression models is reasonably comparable even with ZI outcomes, we advocate the use of the NB regression model due to its clear and straightforward interpretation of the results.

Types and Effects of Telenursing in Home Health Care: A Systematic Review and Meta-Analysis.

Purpose: This systematic review aimed to identify the types and effectiveness of telenursing in home health care (HHC) compared to conventional HHC. Methods: This study followed the Preferred Reporting Items for Systematic Review and Meta-Analysis 2020 guidelines. A random-effects meta-analysis was performed. The risk of bias was assessed using the Risk of Bias 2.0 tool. The quality of bias was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation system. Results: A total of 17 studies published between 2003 and 2022 were included in the review. The majority of the targeted health conditions of the patients were chronic obstructive pulmonary disease or congestive heart failure (70%). We categorized telenursing interventions according to different technology (N = 4) and nursing (N = 7) types. Among the identified types of nursing, fundamental nursing to monitor patients' symptoms was the most representative. Telemonitoring was found to be the most common technology type, followed by synchronous technology using video or telephone. The telenursing outcomes, including health care utilization, physiological/psychological outcomes, and quality of life, varied. In the meta-analysis, participants who received telenursing reported fewer hospital admissions (standardized mean difference [SMD]: -0.18; confidence interval [95% CI]: -0.43 to -0.02) and emergency department visits (SMD: -0.28; 95% CI: -0.45 to -0.10). Conclusion: Telenursing in HHC tends to improve the quality of life and could result in many benefits, including a reduction in health care utilization and facilitating the management of chronic diseases. These results ultimately represent the potential effectiveness of telenursing in community health care settings.
