Patterns of Care and Outcomes of Ambulatory Endovascular Interventions in Lower Extremity Peripheral Arterial Disease.

Lower extremity endovascular intervention (LE-EVI) is gaining popularity as the primary treatment modality for patients with symptomatic peripheral artery disease refractory to noninvasive management. We examined the contemporary patterns of care, regional variation, and outcomes of ambulatory LE-EVI in the United States. The National Ambulatory Surgery Sample was analyzed to identify 266,563 records with peripheral artery disease and LE-EVI between January 1, 2016 and December 31, 2017. The mean age of the study cohort was 68.9 years and 40.5% were women. The majority of the endovascular interventions were performed at large (58.1%), urban teaching (64.1%), private not-for-profit (76.8%) centers, and the southern region accounted for most cases (43%). Periprocedural major adverse renal and cardiovascular events and other complications were 0.5% and 3.3%, respectively. Most patients (97.6%) were discharged home after the procedure. Age, female gender, uncontrolled hypertension, ischemic heart disease, heart failure, arrhythmia, chronic kidney disease, malnutrition, non-Medicare insurance, private for-profit, urban teaching facilities, and southern and midwest regions were associated with higher odds of major adverse renal and cardiovascular events. The mean charges per patient encounter were $56,500, with significant differences across various patient and facility characteristics. In conclusion, our study demonstrates the use, patterns of care, financial aspect, and overall safety of ambulatory LE-EVIs in a real-world setting.

Data on clinical and economic burden associated with pulmonary arterial hypertension related hospitalizations in the United States.

A comprehensive description of the contemporary trends in pulmonary arterial hypertension (PAH) related hospitalizations, associated inpatient outcomes and predictors of worse outcomes were reported in our paper recently published in the International Journal of Cardiology [1]. Our observational analysis utilized ten year of national inpatient sample from January 1st 2007 through December 31st 2016. This Data in Brief companion paper aims to report the specific statistical highlights of the entire ten-year PAH cohort including demographics, hospital characteristics, regional variation, prevalence of comorbidities, and multivariable regression analysis used to examine the factors associated with increased inpatient mortality and prolonged length of stay. Additionally, we report trends in the cost (the actual amount of money reimbursed to the hospitals) of PAH related hospitalizations over the past ten years.

National trends and inpatient outcomes of pulmonary arterial hypertension related hospitalizations - Analysis of the National Inpatient Sample Database.

BACKGROUND: Pulmonary arterial hypertension (PAH) is associated with a significant burden of morbidity and mortality. We examined national trends in PAH-related hospitalizations, associated inpatient mortality (IM), length of stay (LOS) and hospitalization charges from 2007 to 2016, as well as predictors of IM and LOS in this population. METHODS: We used the National Inpatient Sample to identify PAH admissions using International classification of diseases (ICD) codes 416.0 (ICD-9) and I27.0 (ICD-10). Records suggestive of secondary causes of pulmonary hypertension were excluded. 6162 (weighted) records with PAH as the primary diagnosis were analyzed. RESULTS: Mean age was 38.7 years, with the majority being females (78.8%). Overall IM was 6.03%, mean LOS 7.6 ± 0.5 days and mean charges $84,100 ± 6200. PAH-related hospitalizations (per million) (27 in 2007 vs. 28 in 2016, p = 0.19) and associated IM (4.5% in 2007 vs. 6.8% in 2016, p = 0.748) as well as LOS (5.9 days in 2007 vs 6.7 days in 2016, p = 0.304) remained unchanged over the decade. Charges increased by 2.4-fold ($43,800 in 2007 to $103,300 in 2016, p = 0.002). While right heart failure, fluid/electrolyte disorders, cardiac arrhythmia and neurological disorders were associated with increased IM, Hispanic race was found to have a survival benefit. Fluid/electrolyte disorders and coagulopathy were associated with increased LOS. CONCLUSION: Despite significant advancements in PAH therapies over the duration of this study, the rate of PAH hospitalizations, and associated IM and LOS remain unchanged. The study identified the predictors of IM and prolonged LOS in PAH population which could be used for additional risk stratification of these patients.

Risk Factors for Discontinuation of Exclusive Breastfeeding by One Month of Postnatal Age Among High Risk Newborns: An Institution Based Case Control Study.

BACKGROUND: Beyond one month of age, there is generally a drop in the proportion of mothers providing exclusive breastfeeding to their infants. Infants with morbidities during neonatal period have been observed to be at higher risk of discontinuation. OBJECTIVE: To enumerate the prevalent factors behind discontinuation of breastfeeding among high risk newborns by first month of life. MATERIALS AND METHODS: A case control study conducted at high risk newborn followup clinic of a teaching medical institute in northern India between January and May 2013. Infants were divided on the basis of continuation (controls) or discontinuation (cases) of exclusive breastfeeding at one month of age. The socio-demographic factors along with maternal and neonatal medical factors were compared among groups. RESULTS: During the study period, 112 newborns were screened. Forty seven cases and thirty eight controls were enrolled and finally evaluated. Female gender of newborn, less educated mothers and large families were observed to be associated with discontinuation of exclusive breastfeeding during first month of life among high risk newborns. Requirement of parenteral fluids during hospital stay emerged as the only independent medical reason. CONCLUSION: As in healthy newborns, the socio-cultural factors overshadow the medical reasons for discontinuation of exclusive breastfeeding during first month of life among high risk newborns.
