Dataset Information

Datasets for residential GSHP analysis by climate in the United States.

ABSTRACT: This data captures climate information and HVAC energy use for a baseline prototype home and for a replacement alternative energy home. The baseline home is a traditional DX cooling/gas furnace system, and the alternate system is a geothermal heat pump. Cooling degree days (CDD), heating degree days (HDD) and relative humidity were gathered from historical weather data for 12 cities across the contiguous United States [1], [2]. Geothermal heat pump coefficients were generated as inputs to EnergyPlus™ simulation software. These heat pump coefficients are generated by compiling heat pump performance data from 5 market leading, high efficiency residential geothermal heat pump manufacturers. These coefficients can be used to represent a general, market available heat pump in 2-ton, 3-ton, and 4-ton capacities. Baseline prototype home energy use by city was generated by EnergyPlus™ using the prototype home download file from www.energy.gov and the respective weather file for that city. This data can be interpreted as energy use per month by certain HVAC components. The ground source heat pump (GSHP) home energy use by city was generated from EnergyPlus™ and the respective city weather file. The GSHP model was created by the authors to model the alternate closed loop, GSHP system. Reuse potential for heat pump coefficients and home energy use analysis is strong.

Project description:BackgroundWhile residential mobility affects people's health, the dynamic of neighborhood tenure and its associated factors among cancer patients and survivors have not been studied in detail. This cross-sectional study aimed to identify sociodemographic factors associated with neighborhood tenure and relocation after the first cancer diagnosis among U.S. adult cancer survivors and patients.MethodsBased on a nationally representative sample of non-institutionalized civilian adults (≥18 years, n = 185,637) from the 2013-2018 National Health Interview Survey, we compared neighborhood tenure between adults with and without a history of cancer, and identified factors associated with their neighborhood tenure and relocation after the first cancer diagnosis, using propensity score matching, and logistic regression models with survey design incorporated.ResultsAmong adults with cancer (9.0%), 39.6% had a neighborhood tenure ≤10 years (vs. 61.2% among those without cancer), and 25.6% (equivalent to 5.4 million) relocated after their first cancer diagnosis. The odds of having shorter neighborhood tenure was higher among the cancer group in the propensity-matched samples (odds ratio = 1.05; 95% CI: 1.05-1.06; n = 17,259). Among cancer survivors, the odds of neighborhood relocation were negatively associated with increasing age, perceived neighborhood social cohesion, having high school level education, and being married; while positively associated with having family income below the poverty threshold, being uninsured, and living in non-Northeast regions.ConclusionsHigh residential mobility was found among a sizable proportion of adults with a history of cancer, and was associated with multiple socioeconomic factors. Incorporating and addressing modifiable risk factors associated with residential mobility among cancer patients and survivors may offer new intervention opportunities to improve cancer care delivery and reduce cancer disparities.

Project description:We sought to analyze the impact of socioeconomic status (SES) on in-hospital outcomes, cost of hospitalization, and resource use after acute ischemic stroke.We used the 2003-2011 Nationwide Inpatient Sample database for this analysis. All admissions with a principal diagnosis of acute ischemic stroke were identified by using International Classification of Diseases, Ninth Revision codes. SES was assessed by using median household income of the residential ZIP code for each patient. Quartile 1 and quartile 4 reflect the lowest-income and highest-income SES quartile, respectively. During a 9-year period, 775,905 discharges with acute ischemic stroke were analyzed. There was a progressive increase in the incidence of reperfusion on the first admission day across the SES quartiles (P-trend<0.001). In addition, we observed a significant reduction in discharge to nursing facility, across the SES quartiles (P-trend<0.001). Although we did not observe a significant difference in in-hospital mortality across the SES quartiles in the overall cohort (P-trend=0.22), there was a significant trend toward reduced in-hospital mortality across the SES quartiles in younger patients (<75 years) (P-trend<0.001). The mean length of stay in the lowest-income quartile was 5.75 days, which was significantly higher compared with other SES quartiles. Furthermore, the mean adjusted cost of hospitalization among quartiles 2, 3, and 4, compared with quartile 1, was significantly higher by $621, $1238, and $2577, respectively. Compared with the lowest-income quartile, there was a significantly higher use of echocardiography, invasive angiography, and operative procedures, including carotid endarterectomy, in the highest-income quartile.Patients from lower-income quartiles had decreased reperfusion on the first admission day, compared with patients from higher-income quartiles. The cost of hospitalization of patients from higher-income quartiles was significantly higher than that of patients from lowest-income quartiles, despite longer hospital stays in the latter group. This might be partially attributable to a lower use of key procedures among patients from lowest-income quartile.

Project description:BackgroundTransfusion complicates a significant proportion of births in the United States, and Black women have greater prevalence of transfusion at delivery than White women. Antepartum anaemia, a risk factor for peripartum transfusion, is more common among Black women than White women. We aimed to describe the racial distribution of antepartum anaemia in three national datasets and to evaluate the peripartum transfusion rate and characteristics of transfusion recipients, to investigate disparities in haemostatic outcomes.Material and methodsWe performed a retrospective analysis of Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) Maternal-Fetal Medicine Units Network Cesarean Registry (CR), NICHD Consortium on Safe Labor Registry (CSL), and a cohort of deliveries at Universal Health Services hospitals (UHS). Univariable associations and multivariable logistic regressions were calculated between race, anaemia and transfusion. Covariates included age, parity, smoking, body mass index, type of insurance, and delivery mode.ResultsWe included n=56,964 deliveries from CR (28% Black), 87,465 from UHS (12% Black), and 140,324 from CSL (24% Black). Anaemia prevalence was 8% in CR, 7% in UHS, and 13% in CSL. Anaemia was more common among Black patients (ORs 2.52, 2.61, and 1.48 respectively) and was associated with transfusion in all databases (ORs 6.46 [95% CI 5.78-7.22]; 5.79 [4.74-7.27]; 1.27 [1.18-1.37] respectively). After adjusting for covariates, Black patients had greater odds of transfusion than non-Black patients in CR (aOR 1.32 [1.16-1.50]), but not in UHS or CSL (aORs 1.19 [0.89-1.59] and 0.40 [0.36-0.44] respectively).DiscussionIn our retrospective cohort study using three US registries, we emphasized the link between anaemia and transfusion. Although anaemia was more prevalent among Black patients, the race-transfusion relationship differed between databases, indicating other unexplored factors are involved.
