Initial Hospitalization (initial + hospitalization)
Selected AbstractsMortality differences among organisms causing septicemia in hemodialysis patientsHEMODIALYSIS INTERNATIONAL, Issue 1 2006Mark D. DANESE Abstract Septicemia is a serious problem in hemodialysis patients because it can lead to life-threatening complications and a persistently elevated risk of death. Most analyses have not examined whether there are differences in mortality risk among the organisms that cause these episodes of septicemia. This study was a retrospective cohort analysis of first septicemia hospitalizations during the first year of hemodialysis. Time to death (both in-hospital and within 12 weeks post-discharge) was compared among the different septicemia-causing organisms based on discharge diagnoses in Medicare billing data from 1996 to 2001. The effect of various complications on mortality risk was also evaluated. There were 22,130 septicemia hospitalizations identified. The most common organism identified was Staphylococcus aureus (27%), with no other organism having an incidence >10%. The overall unadjusted death rate from admission through 12 weeks of follow-up was 34%. During the first hospitalization, the death rate was 14%, and during the 12-week period after the hospitalization it was 20%. In adjusted analyses, S. aureus was associated with a 20% higher risk of death both during the in-hospital period and the 12-week post-discharge period, when compared with all other specified organisms. Hospitalizations complicated by meningitis, stroke, or endocarditis were also associated with increased risk of mortality, independent of the organism causing septicemia. Septicemia hospitalizations are associated with a high mortality rate,both during the initial hospitalization and after discharge. Meningitis, stroke, and endocarditis represent particularly serious complications. Overall, septicemia hospitalizations (especially for S. aureus) are serious events, and patients would benefit from better treatment and prevention.

The purpose of this research was to compare the economic and health status impacts of each treatment strategy. Resource utilization data were collected for the 479 patients randomized in OPUS-I. Itemized cost estimates were derived from primary hospital charge data gathered in previous multicenter trials evaluating coronary stents, and adjusted to approximate 1997 Medicare-based costs for a cardiac population. Health status at 6 months was assessed using the Seattle Angina Questionnaire (SAQ). Initial procedure related costs for patients treated with a primary stent strategy were higher than those treated with optimal PTCA/provisional stent ($5,389 vs $4,339, P<0.001). Costs of initial hospitalization were also higher for patients in the primary stent group ($9,234 vs $8,434, P<0.01) chiefly because of the cost differences in the index revascularization. Mean 6-month costs were similar in the two groups; however, there was a slight cost advantage associated with primary stenting. Bootstrap replication of 6-month cost data sustained the economic attractiveness of the primary stent strategy. There were no differences in SAQ scores between treatment groups. In patients undergoing single vessel coronary angioplasty, routine stent implantation improves important clinical outcomes at comparable, or even reduced cost, compared to a strategy of initial balloon angioplasty with provisional stenting. [source] Predictors of length of stay for pediatric liver transplant recipientsLIVER TRANSPLANTATION, Issue 8 2004John C. Bucuvalas The resources that are directed towards the care of liver transplant recipients are substantial. Approximately 100 million dollars are spent on the hospitalization of the 400,500 children in the United States who undergo liver transplantation each year. Using length of stay as a surrogate marker for hospital resource use, we sought to identify factors that impact length of stay and assess the trends of hospitalization after liver transplantation for a representative population of pediatric liver transplant recipients. The study population was comprised of 956 patients who underwent primary liver transplantation between 1995 and 2003 and survived at least 90 days. Data were retrieved from the Studies of Pediatric Liver Transplantation data registry. The primary outcome was the length of initial hospitalization after liver transplantation. Independent variables were age, gender, race, pediatric end-stage liver disease score (PELD), year of transplantation, organ type, primary disease, length of operation, and insurance status. The mean and standard deviation of length of stay after liver transplantation was 24.0 ± 24.5 days. Multivariate analyses showed that increased hospital stay was associated with infants less than 1 year of age, fulminant liver failure, receiving a technical variant organ from a cadaveric donor, government insurance, and transplant era (before 1999 vs. 1999 or later). Decreasing height z-scores and increasing length of operation were also associated with increased hospital stay. In conclusion, these parameters accounted for only 11% of the total variance, suggesting that post-transplant complications and course account for much of the variability of resource use in the immediate post-transplant period.

[source] The impact of the evolution of invasive surgical procedures for low back pain: a population based study of patient outcomes and hospital utilizationANZ JOURNAL OF SURGERY, Issue 9 2009Rachael Elizabeth Moorin Abstract Background:, Low back pain (LBP) is a ubiquitous health problem in Western societies, and while clinical decision making for patients requiring hospitalization for LBP has changed significantly over the past two decades, knowledge of the net impact on patient outcomes and health care utilization is lacking. The aim of this study was to evaluate the effectiveness of changes in the medical control of lumbar back pain in Western Australia in terms of the rate of patient readmission and the total bed days associated with readmissions. Methods:, A record linkage population-based study of hospitalization for LBP from 1980,2003 in Western Australia was performed. The rate of admission for LBP, changes in re-admission rates and number of bed days accrued 1 and 3 years post-initial admission over time adjusted for potential confounders was evaluated. Results:, The annual rate of first-time hospitalization for LBP halved. The proportion of females admitted increased (+6%). The disease severity increased and the proportion of individuals having an invasive procedure also increased (+75%) over the study period. While rate of readmission for non-invasive procedures fell, readmission for invasive procedures increased over the study period. Overall, the number of bed days associated with readmission reduced over time. Conclusion:, Between 1980 and 2003, there has been a shift from non-invasive procedural treatments towards invasive techniques both at the time of initial hospitalization and upon subsequent readmission. While overall readmission rates were unaffected, there was a reduction in the number of bed days associated with readmissions. [source] Acute treatment costs of intracerebral hemorrhage and ischemic stroke in ArgentinaACTA NEUROLOGICA SCANDINAVICA, Issue 4 2009M. C. Christensen Background and purpose,,, Stroke is the third leading cause of death in Argentina, yet little information exists on the acute treatment provided for stroke or its costs. This study estimates the national costs of the acute treatment of first-ever intracerebral hemorrhage (ICH) and ischemic stroke (IS) in Argentina. Methods,,, Retrospective hospital-based inception study design using data on resource use and costs from high-volume stroke centers in Argentina, and published population-based incidence data. Treatment provided at two large urban hospitals were evaluated in all patients admitted with a first-ever stroke between 1 January 2004 and 31 August 2006, and costs were assigned using appropriate unit cost data for all resource use. Cost estimates in Argentinian pesos were converted to US dollars ($) using the 2005 purchasing power parity index. National costs of acute treatment for incident strokes were estimated by extrapolation of average costs estimates to national incidence data. Assumptions of the average cost of stroke treatment on a national scale were examined in sensitivity analysis. Results,,, The acute care of 167 patients with stroke was thoroughly evaluated from hospital admission to hospital discharge. Mean length of hospital stay was 35.4 days for ICH and 13.0 days for IS. Ninety-one percent of the patients with ICH and 68% of the patients with IS were admitted to an ICU for a mean length of stay (LOS) of 12.9 ± 20.3 and 3.6 ± 5.9 days respectively. Mean total costs of initial hospitalization were $12,285 (SD ±14,336) for ICH and $3888 (SD ±4018) for IS. Costs differed significantly by Glasgow Coma Scale (GCS) score at admission, development of pneumonia and infections during hospitalization, and functional outcome at hospital discharge. Aggregate national healthcare expenditures for acute treatment of incident ICH were $194.2m (range 97.1,388.4) and $239.9m for IS (range 119.9,479.7). Conclusion,,, The direct hospital costs of incident ICH and IS in Argentina are substantial and primarily driven by stroke severity, in-hospital complications and clinical outcomes. With the expected increase in the incidence of stroke over the coming decades, these results emphasize the need for effective preventive and acute medical care. [source] Prediction of length of stay for stroke patientsACTA NEUROLOGICA SCANDINAVICA, Issue 1 2007P. Appelros Objectives ,, To examine the factors that influence acute and total length of stay (LOS) for stroke patients. Materials and methods ,, The basis of this investigation was a population-based cohort of first-ever stroke patients (n = 388). Subjects were survivors of the initial hospitalization (n = 295). Age, sex, social factors, risk factors, dementia, stroke type, and stroke severity, measured with the NIH stroke scale (NIHSS), were registered. Results ,, Mean acute LOS was 12 days and mean total LOS was 29 days. Independent predictors of acute LOS were stroke severity, lacunar stroke, prestroke dementia, and smoking. Independent predictors of total LOS were stroke severity and prestroke activities of daily living (ADL) dependency. The NIHSS items that best correlated with LOS were paresis, unilateral neglect and level of consciousness. Conclusions ,, Stroke severity is a strong and reliable predictor of LOS. The results of this study can be used as a baseline for evaluating cost-effectiveness of stroke care changes, e.g. organizational changes or evaluation of new drugs. [source] Pre- and post-discharge feeding of very preterm infants: impact on growth and bone mineralizationCLINICAL PHYSIOLOGY AND FUNCTIONAL IMAGING, Issue 4 2003Sangita Kurl Summary In this prospective study we examined (1) how the nutritional status of very preterm infants, judged by growth measures and biochemical values, evolved during the initial hospitalization; (2) the effect of feeding on growth after discharge from hospital; and (3) the risk factors associated with low lumbar bone mineral content (BMC) later in infancy. Sixty-four former preterm infants had their lumbar spine (L2,L4) BMC assessed by dual energy X-ray absorptiometry when they weighed between 5 and 7 kg. Predicted BMC values were calculated based on our previously reported reference lumbar BMC data. These values were used to convert the preterm infants' BMC values into percentages. The extremely preterm group (gestational age ,28 weeks) had significantly more respiratory morbidity and longer duration of hospital stay than the more mature infants. Both groups developed growth retardation and malnutrition during the hospital stay. Exclusive breastfeeding after discharge from hospital supported linear catch-up growth and weight gain but was associated with a 7·0 (1·2,41·7)-fold risk of having low BMC values. The other factors associated with the risk of having low BMC values later in infancy were low serum phosphate levels at 6 weeks, with a 7·8 (1·6,37·0)-fold risk, and male gender, with a 4·3 (1·2,16·1)-fold risk. Appropriately designed interventional studies are needed to improve the growth and nutrition of these infants during initial hospitalization. In order to improve the postdischarge nutrition, we suggest that the amount and duration of multicomponent human milk fortification should be studied further to provide individualized nutrition throughout the catch-up growth period until the end of the first year of life.
