Predictors of Rehospitalization and Mortality in Diabetes-Related Hospital Admissions

Nationwide clinico-epidemiological treatment analysis of adult patients with tumors of cerebellopontine angle and internal acoustic meatus in Poland during 2011-2020

OBJECTIVE

The aim of this study is to report the epidemiologic characteristics of tumors of the cerebellopontine angle (CPAT) and internal acoustic meatus in adult Polish population throughout the second decade of XXI century and to analyze their treatment.

MATERIAL AND METHODS

A retrospective analysis of patients with cerebellopontine angle (CPA) and internal acoustic meatus tumors diagnosed in Poland in 2011-2020 was performed. Data recorded in the National Health Fund (NHF) database were analyzed. International Classification of Diseases codes (ICD-9 and ICD-10) were used to identify study group patients and treatment procedures.

RESULTS

From 2011 to 2020 6,173 Polish adult patients were diagnosed with cerebellopontine angle and internal acoustic meatus tumors. The average incidence in Poland is 1.99 per 100,000 residents/year. It mostly affects women (61.64%), and the average age of patients is 53.78 years. The incidence has steadily increased over the past decade. Treatment has changed significantly over the years, with a definite increase in the number of patients treated with radiotherapy (from 0.54 to 19.34%), and a decrease in surgical therapies (from 41.67 to 6.8%). The most common symptoms were vertigo and/or dizziness (43.48%) and sensorineural hearing loss (39.58%). 4.65% of patients suffered from sudden deafness, in this group of patients the risk of CPAT detection was the highest (6.25 / 1000 patients).

CONCLUSIONS

The total incidence of CPAT and demographic characteristics of patients were comparable to other studies. Our study demonstrated the increased number of patients are being treated with radiotherapy and fewer with microsurgery. Sudden sensorineural hearing loss (SSNHL) is an uncommon manifestation of CPAT but proper diagnosis should be undertaken because the risk of diagnosis such tumors is greater in this group.

Obesity Metabolic Phenotypes and Unplanned Readmission Risk in Diabetic Kidney Disease: An Observational Study from the Nationwide Readmission Database

BACKGROUND AND AIM

Obesity is a potentially modifiable factor for reducing readmissions, with heterogeneity that varies according to the metabolic status. Our objective was to examine the independent or mutual relationship between obesity and metabolic abnormalities and diabetic kidney disease (DKD)-related hospitalizations.

METHODS

493,570 subjects with DKD were enrolled in the 2018 Nationwide Readmission Database (NRD, United States). The at-risk population was reclassified into refined obesity subtypes based on the body mass index (BMI) classification of metabolic abnormalities (hypertension and/or dyslipidemia) to investigate the 180 d readmission risk and hospitalization costs related to DKD.

RESULTS

The overall readmission rate was 34.1%. Patients with metabolic abnormalities, regardless of obesity, had a significantly higher risk of readmission compared to non-obese counterparts (adjusted HR, 1.11 [95% CI, 1.07-1.14]; 1.12 [95% CI, 1.08-1.15]). Hypertension appeared to be the only metabolic factor associated with readmission among individuals with DKD. Obesity without metabolic abnormalities was independently associated with readmission (adjusted HR,1.08 [1.01,1.14]), especially among males and those >65 years (adjusted HR,1.10 [1.01-1.21]; 1.20 [1.10-1.31]). Women or those ≤65 years with metabolic abnormalities (all p <0.050) had elevated readmission rates, regardless of obesity; however, no such trend was observed in obese subjects without metabolic abnormalities (adjusted HR, 1.06 [0.98,1.16]). Additionally, obesity and metabolic abnormalities were associated with elevated hospitalization costs (all p <0.0001).

CONCLUSIONS

Increased BMI and hypertension are positively associated with readmissions and related costs among patients with DKD, which should be considered in future studies.

Hospital-care utilization and medical cost patterns among patients with insulin-dependent diabetes

OBJECTIVE

Using claims data from an integrated payer-provider, we compared the costs incurred by insulin-dependent diabetes mellitus (IDDM) patients who received Hospital Inpatient/Observation/Emergency Department care (HIghER care) for diabetes-related events with those who did not receive such care to identify a target population for interventions in future studies.

METHODS

A retrospective study pooled real-world claims data for IDDM with type 1 or type 2 DM between July 1, 2018 and June 30, 2019. Medical claims were used to calculate the total and diabetes-related allowed medical costs to the Enterprise and per-member per month (pmpm) costs.

RESULTS

A total of 19,378 members' medical and prescription drug coverage were analyzed. Only 8.4% of the IDDM population received HIghER care but incurred 20% of medical expenses, and nearly 40% of diabetes-related medical costs. For HIghER care patients, medical spending was higher in every inpatient and outpatient category (Wilcoxon two sample tests, all p < 0.0001). Non-diabetes related prescription drug costs were greater in this group (Wilcoxon, Z = 2.2879, p = 0.0221), but diabetes-related prescription drug costs were higher for non-HIghER care (Wilcoxon, Z = -9.5918, p < 0.0001). In a longitudinal study of 29,602 patients over 24 months, prior-year receipt of HIghER care was a significant predictor of HIghER care the subsequent year (odds ratio 3.28) CONCLUSIONS: Medical spending for HIghER care patients was disproportionately high and greater in every inpatient and outpatient category. Receipt of HIghER care in the previous year was highly predictive of HIghER care episodes the following year.
