Efficacy of the unified protocol for transdiagnostic cognitive-behavioral treatment for depressive and anxiety disorders: a randomized controlled trial

Background The efficacy of the unified protocol of the transdiagnostic treatment for emotional disorders (UP) has been poorly studied in patients with depressive disorders. This study aimed to examine the efficacy of UP for improving depressive symptoms in patients with depressive and/or anxiety-related disorders. Methods This assessor-blinded, randomized, 20-week, parallel-group, superiority study compared the efficacy of the UP with treatment-as-usual (UP-TAU) v. wait-list with treatment-as-usual (WL-TAU). Patients diagnosed with depressive and/or anxiety disorders and with depressive symptoms participated. The primary outcome was depressive symptoms assessed by GRID-Hamilton depression rating scale (GRID-HAMD) at 21 weeks. The secondary outcomes included assessor-rated anxiety symptoms, severity and improvement of clinical global impression, responder and remission status, and loss of principal diagnosis. Results In total, 104 patients participated and were subjected to intention-to-treat analysis [mean age = 37.4, s.d. = 11.5, 63 female (61%), 54 (51.9%) with a principal diagnosis of depressive disorders]. The mean GRID-HAMD scores in the UP-TAU and WL-TAU groups were 16.15 (s.d. = 4.90) and 17.06 (s.d. = 6.46) at baseline and 12.14 (s.d. = 5.47) and 17.34 (s.d. = 5.78) at 21 weeks, with a significant adjusted mean change difference of −3.99 (95% CI −6.10 to −1.87). Patients in the UP-TAU group showed significant superiority in anxiety and clinical global impressions. The improvement in the UP-TAU group was maintained in all outcomes at 43 weeks. No serious adverse events were observed in the UP-TAU group. Conclusions The UP is an effective approach for patients with depressive and/or anxiety disorders.

The epidemiology of falls in Portugal: An analysis of hospital admission data

Background Falls are a common cause of injury and pose an increased risk of morbidity, mortality, and lifelong disability. Falls encompass a troublesome definition and can pose challenges in epidemiological studies. Data on fall-related hospital admissions in Portugal remain unpublished. This study aimed to examine the epidemiology of fall-related hospital admissions in the Portuguese population between 2010 and 2018. It also aimed to examine annual rates of fall-related hospital admissions using three methodological approaches. Methods The Portuguese Hospital Morbidity Database was used to identify all cases resulting in one or more inpatient admission in public hospitals related to falls from 2010 to 2018. Fall-related hospital admissions were described by age groups, sex, geographical area of residence, and type of fall. Annual rates were computed using three approaches: i) based on the number of inpatient admissions with an ICD code of fall, ii) based on the number of patients admitted to inpatient care with an ICD code of fall, and iii) based on the number of inpatient admissions with a principal diagnosis of injury. Results Between 2010 and 2018, 383,016 fall-related admissions occurred in 344,728 patients, corresponding to 2.1% of the total number of hospitalizations during the same period. Higher rates were seen among the younger (20–25) and the oldest age groups (+85), males until the age of 60, females from the age of 60, and areas of residence with a higher aging index. An overall rate of falls per 100,000 population was estimated at 414 (based on number of admissions), 373 (based on number of patients) and 353 (based on number of admissions with a principal diagnosis of injury). Conclusions This study provides an overall picture of the landscape of falls in a scarcely explored setting. The results aim to contribute to identifying appropriate preventive interventions and policies for these populations.

Epidemiology and Outcomes of Community-acquired Escherichia coli Pneumonia

Objective To describe the epidemiology, risk factors and outcomes of community-acquired Escherichia coli pneumonia in comparison to other gram-negative and pneumococcal pneumonias. Methods E.coli is an under recognized cause of bacterial community-acquired pneumonia (CAP). We conducted a large retrospective cohort study of adult patients admitted with pneumonia to 173 US hospitals included in Premier Research database from July 2010–June 2015. Patients were included if they had principal diagnosis code for pneumonia, or a principal diagnosis of respiratory failure or sepsis with secondary diagnosis of pneumonia and had a positive blood or respiratory culture obtained on hospital day 1. The primary outcome was in-hospital case fatality. Secondary outcomes included intensive care unit (ICU) admission, invasive mechanical ventilation (IMV) and use of vasopressors. Results Of 8,680 patients with pneumonia and positive blood or respiratory cultures, 1,029 (7.7%) had E.coli CAP. Patients with E.coli pneumonia were older and more likely to have a principal diagnosis of sepsis. Patients with E.coli pneumonia had significantly higher case fatality than patients with pneumococcal pneumonia (adjusted odds ratio, 1.55 [95% CI, 1.23–1.97]) but not significantly different than other gram-negative pneumonias (adjusted odds ratio, 1.06 [95% CI, 0.85–1.32]). Approximately 36% of the isolates were resistant to fluoroquinolones; 9.3% were resistant to ceftriaxone. Conclusions E.coli is an important cause of severe CAP; with higher mortality than pneumococcal pneumonia but similar to other gram-negative pneumonias. The rate of fluoroquinolone resistance was high and empiric fluoroquinolones should be used with caution in these patients.

1314. Descriptive Epidemiology of 30-day Readmissions among Survivors of Hospitalization with Bacterial Nosocomial Pneumonia in the US, 2012-2019

Background Nosocomial pneumonia (NP) remains associated with excess morbidity and mortality. The effect of NP on other measures of outcome and quality, such as re-admission at 30 days, remains unclear. Moreover, differing types of NP may have varying impacts on re-admissions. Methods We conducted a multicenter retrospective cohort study within the Premier Research database, a source containing administrative, pharmacy, and microbiology data. The rate of rehospitalization at 30 days following the index discharge served as our primary endpoint. We compared NP patients readmitted with pneumonia (RaP) as the principal diagnosis to those readmitted for other reasons (RaO). We also compared readmission rates as function of the type of NP: ventilator-associated bacterial pneumonia (VABP), ventilated hospital-acquired bacterial pneumonia (vHABP), and non-ventilated HABP (nvHABP). Results Among 17,819 patients with NP, 14,123 (79.3%) survived to discharge, of whom 2,151 (15.2%) required an acute readmission within 30 days of index discharge. Of these, 106 (4.9%) were RaP, and the remainder were RaO. At index hospitalization, RaP patients were older (mean age (SD) 67.4 (13.9] vs. 63.0 (15.2) years), more likely medical (44.3% vs. 36.7%), and less chronically ill (median [IQR] Charlson scores (3 [2-5] vs. 4 [2-5]) than persons with RaO. Bacteremia (10.4% vs. 17.5%), need for vasopressors (15.1% vs. 20.0%), dialysis (9.4% vs. 16.5%), and/or sepsis (9.4% vs. 16.5%) or septic shock 14.2% vs. 17.1%) occurred less frequently in the RaP group. With respect to NP type, nvHABP was most common in RaP (47.2%) and VABP in RaO (38.1%). Conclusion One in seven survivors of a hospitalization complicated by NP requires an acute rehospitalization within 30 days. However, few of these readmissions had a principal diagnosis of pneumonia, irrespective of NP type. This suggests that short-term readmission does not capture the quality of care initially delivered to patients for their NP. Of the 5% of NP subjects with RaP, the plurality initially suffered from nvHABP.

1430. Descriptive Epidemiology of Emergency Department Visits with cUTI in the US, 2012-2018

Background Urinary tract infections (UTI) represent a substantial burden to the healthcare system. In the early 2000s annual UTI admissions numbered 100,000, and these infections resulted in over 1 million emergency department (ED) visits. While only a fraction of total UTI volume, the estimated cost of complicated (cUTI) to the healthcare system exceeded &3.5 billion. We set out to evaluate the contemporary burden of cUTI in the US in terms of ED visits annually. Methods We conducted a retrospective multicenter cohort study within the National Emergency Department (NEDS) database, a 20-percent stratified sample of all US hospital-based EDs, from 2012-2018, to explore characteristics of patients discharged with a cUTI diagnosis. We applied a previously published algorithm to identify cUTI using administrative coding. We applied survey methods to develop national estimates. Results Among 3,010,997 ED visits with cUTI, 43.3% were female, and 59.0% were age 65 years or older. Commensurately, Medicare was the primary payor in 62.8% of the visits. The majority of the patients (59.1%) presented to metropolitan teaching hospitals, and plurality were in the Southern US (39.6%). There was a narrow range in the visits’ seasonal variation, from 6.4% occurring in February to 7.9% in October. cUTI was the principal diagnosis in 48.5% of all cUTI visits. In the remaining 51.5%, sepsis was the most common principal diagnosis (33.9%), but severe sepsis and septic shock codes each appeared in 4.9%. Of all cUTI ED visits, 21.4% had catheter-associated UTI. While only 19.8% had a code for pyelonephritis, 2,050,548 (68.1%) were admitted to the hospital. Mortality in the ED was 0.02%. Conclusion During the seven-year span, there were over 3 million ED visits for cUTI. Although fewer than 1 in 10 patients met criteria for severe sepsis/septic shock, approximately 2/3rds of cUTI patients presenting to the ED were subsequently hospitalized.

Increased Inpatient Mortality for Cardiovascular Patients During the First Wave of the COVID‐19 Epidemic in New York

Background The acuity and magnitude of the first wave of the COVID‐19 epidemic in New York mandated a drastic change in healthcare access and delivery of care. Methods and Results We retrospectively studied patients admitted with an acute cardiovascular syndrome as their principal diagnosis to 13 hospitals across Northwell Health during March 11 through May 26, 2020 (first COVID‐19 epidemic wave) and the same period in 2019. Three thousand sixteen patients (242 COVID‐19 positive) were admitted for an acute cardiovascular syndrome during the first COVID‐19 wave compared with 9422 patients 1 year prior (decrease of 68.0%, P <0.001). During this time, patients with cardiovascular disease presented later to the hospital (360 versus 120 minutes for acute myocardial infarction), underwent fewer procedures (34.6% versus 45.6%, P <0.001), were less likely to be treated in an intensive care unit setting (8.7% versus 10.8%, P <0.001), and had a longer hospital stay (2.91 [1.71–6.05] versus 2.87 [1.82–4.95] days, P =0.033). Inpatient cardiovascular mortality during the first epidemic outbreak increased by 111.1% (3.8 versus 1.8, P <0.001) and was not related to COVID‐19‐related admissions, all cause in‐hospital mortality, or incidence of out‐of‐hospital cardiac deaths in New York. Admission during the first COVID‐19 surge along with age and positive COVID‐19 test independently predicted mortality for cardiovascular admissions (odds ratios, 1.30, 1.05, and 5.09, respectively, P <0.0001). Conclusions A lower rate and later presentation of patients with cardiovascular pathology, coupled with deviation from common clinical practice mandated by the first wave of the COVID‐19 pandemic, might have accounted for higher in‐hospital cardiovascular mortality during that period.

Rate and Predictors of 30-Day Readmission following Diabetic Ketoacidosis in Type 1 Diabetes Mellitus: A US Analysis

Introduction This study aimed to describe rates and characteristics of non-elective 30-day readmission among adult patients with diabetes mellitus type 1 (T1DM) hospitalized for diabetic ketoacidosis (DKA) and also identify predictors of readmission. Methods The study analyzed the 2018 Nationwide Readmission Database. DKA hospitalizations in patients with T1DM were classified using ICD-10-CM codes. We utilized Chi-square tests to compare baseline characteristics between readmissions and index hospitalizations. Multivariable cox regression was employed to identify independent predictors of readmission. Following this, we developed a 30-day readmission risk scoring system based on independent predictors. Results The 30-day all-cause readmission rate for DKA was 19.4%. A majority of patients (64.8%) had DKA as the principal diagnosis on readmission. Readmitted patients had a significantly higher mean age (35.3 vs. 34.9 years, p=0.018) and a higher proportion of females (52.8 vs. 49.6%,p&lt;0.001) compared to the index admission. Readmission following DKA was associated with higher odds of inpatient mortality (0.69 vs. 0.24%, OR: 2.84, 95% CI: 1.99 – 4.06, p&lt;0.001). Independent predictors of 30-day all-cause readmission included female sex, index hospitalizations with Charlson Comorbidity Index (CCI) score of 3 or greater, and being discharged against medical advice (AMA). Conclusion The readmission rate for DKA in T1DM patients is high, and most patients have DKA as the principal diagnosis on readmission. A CCI equal to or greater than 3, hypertension, female sex, and being discharged AMA were significant predictors of readmission.

The association between myelodysplastic syndromes (MDS) and inflammatory bowel diseases (IBD): Analysis of Nationwide Inpatient Sample (NIS) database.

e19033 Background: The co-occurrence of MDS and IBD has been gradually recognized in the literature. Yet, large-scale national studies are required to investigate this observed association further. We aimed to delineate the clinical features, outcomes between the concurrent of MDS with IBD and MDS or IBD alone in a nationally representative database. Methods: Data were obtained from the NIS 2010-2014, using appropriate ICD-9 codes to identify patients who were admitted with a principal diagnosis of MDS with IBD as secondary (MDS-1/IBD) and MDS without IBD and patients who were admitted with a principal diagnosis of IBD with MDS (IBD-1/MDS) and without MDS. We assessed the mortality rate as the primary outcome, mean length of stay (LOS), and rate of blood transfusion as secondary outcomes by Pearson χ2 -test and univariate regression (logistic regression). Results: We identified 190 hospitalizations for MDS-1/IBD and 4895 hospitalizations for IBD-1/MDS. The mean LOS was higher for MDS-1/IBD group than for IBD or MDS only (11.7 vs. 6.1 and 7 days). However, the mortality rate in the MDS-1/IBD group was lower than in patients with IBD or MDS only (2.6% vs. 3.8% and 4.4%). While the rate of blood transfusion was higher among males in the MDS group, it was significantly higher among females when there is a concurrent MDS-1/IBD. However, the differences were not significant when MDS is not the primary diagnosis i.e IBD-1/MDS. In univariate analysis, age and Charlson comorbidity index were significantly associated with an increased mortality rate when there are IBD and MDS than MDS or IBD alone. Conclusions: While unable to assess appropriateness, NIS data indicate that there are significant differences in outcomes such as mean LOS, rate of blood transfusion and mortality rate when there is a concurrence of MDS and IBD than MDS or IBD alone. The underlying pathogenicity remains unclear and warrants additional study.[Table: see text]
