A Correlative Study of Epidemiological Mortality and Morbidity Rates: Appalachian vs Non-Appalachian Counties within Kentucky
In this study, differences in mortality rates were statistically analyzed between Kentucky Appalachian County Populations (KACP) and Kentucky Non-Appalachian County Populations (KnACP) for 2013. Health – risk factors and socio – economic conditions were also assessed to determine if they put KACP at a higher risk of the five most common causes of death in Kentucky. Estill County, a KACP, was also specifically examined for its mortality and health – risk factor rates. By examining the 2013 database provided by the Kentucky Department for Public Health (KDPH) and the Center for Disease Control and Prevention (CDC), it was determined that there is a significant increase in mortality rates of malignant neoplasms and heart disease in the KACP population compared to KnACP. The KACP population also has significantly increased rates of hypertension, diabetes, smoking, and obesity; all of which contribute to the significance of KACP mortality rates. Subsequently, socio – economic factors such as median house – hold income showed a significant decrease for KACP compared to KnACP which indirectly affects the mortality rates of KACP. Estill County also showed an increase in mortality rates, as well as, health-risk factors compared to KACP. These findings indicate that the populations of KACP are at higher risk of dying from malignant neoplasms and heart disease due to a significant increase in hypertension, smoking, diabetes, and obesity. To correct this overwhelming health issue, improving the quality of and access to healthcare for the KACP’s needs to be a focus. Projects including government resources such as more funding for free clinics, as well as community based efforts to reduce smoking, etc. is of utmost importance
Viewpoint: A response to Screening and isolation to control methicillin-resistant Staphylococcus aureus: Sense, nonsense, and evidence
Surveillance and isolation for the prevention of methicillin-resistant Staphylococcus aureus (MRSA) has become a controversial topic, one that causes heated debate and appears to be surrounded by both politics and industrial conflicts-of-interest. There have been calls from numerous authors for a movement away from rigid mandates and toward an evidence-based medicine approach. However, much of the evidence can be viewed with an entirely different interpretation. Two major studies with negative findings have had an adverse impact on recommendations regarding active detection and isolation (ADI) for MRSA. However the negative findings in these studies can be explained by shortcomings in study implementation rather than the ineffectiveness of ADI. The use of daily chlorhexidine bathing has also been proposed as an alternative to ADI in ICU settings. There are shortcomings regarding the evidence in the literature concerning the effectiveness of daily chlorhexidine bathing. One of the major concerns with universal daily chlorhexidine bathing is the development of bacterial resistance. The use of surveillance and isolation to address epidemics and common dangerous pathogens should solely depend upon surveillance and isolation\u27s ability to prevent further spread to and infection of other patients through indirect contact. At present, there is a preponderance of evidence in the literature to support continuing use of surveillance and isolation to prevent the spread of MRSA
Much Work Still to Be Done to Prevent Central Line-Associated Bloodstream Infections
Central Line Associated Bloodstream Infections (CLABSI) are all too common and often fatal events. To estimate the number of preventable CLABSIs, the authors analyzed SIR (Standardized Infection Ratio) and the number of CLABSI data from Hospital Com-pare. Several studies have suggested that an SIR of 0.35 may be achievable. If all institutions were able to perform at this level, then almost 50% of CLABSI would be prevented
The Relationship Between Tort Reform and Medical Utilization
NTRODUCTION: The hidden cost of defensive medicine has been cited by policymakers as a significant driving force in the increase of our nation\u27s health-care costs. If this hypothesis is correct, one would expect that states with higher levels of tort reform will have a decrease in Medicare utilization and that medical utilization will decrease after tort reform is enacted. METHODS: State-level reimbursement data for years 1999 to 2010 (the last year available) was obtained from the Dartmouth Atlas of Health Care. Medical tort rankings for the 50 states were obtained from the Pacific Research Institute (PRI) and correlated with state medical utilization for the year 2010. In 3 states, Mississippi, Nevada, and Texas, data were available to make pretort and posttort reform comparisons. RESULTS: Data analysis between total state Medicare Reimbursements and the PRI\u27s tort rankings showed no significant observed correlation. In 6 Medicare utilization categories (total Medicare, hospital and skilled nursing facility, physician, home health agency, hospice, and durable medical equipment), a negative trend was observed when correlated with PRI tort rankings. This trend does not support the hypothesis that defensive medicine is a major driver of health-care expenditures. Tracking expenditures in the states of Texas, Nevada, and Mississippi, before and after passage of comprehensive medical tort reform gave inconsistent results and did not demonstrate substantial or meaningful total Medicare savings. In Mississippi, there was a trend of decreased expenditures after medical tort reform was passed. However, in Texas, where 80% of the analyzed enrollees resided, there was a trend of progressive increasing expenditures after tort reform was passed. CONCLUSION: The comparison of the Dartmouth Atlas Medicare Reimbursement Data with Malpractice Reform State Rankings, which are used by the PRI, did not support the hypothesis that defensive medicine is a driver of rising health-care costs. Additionally, comparing Medicare reimbursements, premedical and postmedical tort reform, we found no consistent effect on health-care expenditures. Together, these data indicate that medical tort reform seems to have little to no effect on overall Medicare cost savings
View point: gaps in the current guidelines for the prevention of Methicillin-resistant Staphylococcus aureus surgical site infections
The authors advocate the addition of two preventative strategies to the current United State’s guidelines for the prevention of surgical site infections. It is known that Staphylococcus aureus, including Methicillin-resistant Staphylococcus aureus (MRSA), carriers are at a higher risk for the development of infections and they can easily transmit the organism. The carriage rate of Staph. aureus in the general population approximates 33%. The CDC estimates the carriage rate of MRSA in the United States is approximately 2%. The first strategy is preoperative screening of surgical patients for Staph. aureus, including MRSA. This recommendation is based upon the growing literature which shows a benefit in both prevention of infections and guidance in preoperative antibiotic selection. The second is performing MRSA active surveillance screening on healthcare workers. The carriage rate of MRSA in healthcare workers approximates 5% and there are concerns of transmission of this pathogen to patients. MRSA decolonization of healthcare workers has been reported to approach a success rate of 90%. Healthcare workers colonized with dangerous pathogens, including MRSA, should be assigned to non-patient contact work areas. In addition, there needs to be implemented a safety net for both the worker’s economic security and healthcare. Finally, a reporting system for the healthcare worker acquisition and infections with dangerous pathogens needs to be implemented. These recommendations are needed because Staph. aureus including MRSA is endemic in the United States. Policies regarding endemic pathogens which are to be implemented only upon the occurrence of a facility defined “outbreak” have to be questioned, since absence of infections does not mean absence of transmission. Optimizing these policies will require further research but until then we should error on the side of patient safety
The incidence of MRSA infections in the United States: is a more comprehensive tracking system needed?
A review of epidemiological studies on the incidence of MRSA infections overtime was performed along with an analysis of data available for download from Hospital Compare (https://data.medicare.gov/data/hospital-compare). We found the estimations of the incidence of MRSA infections varied widely depending upon the type of population studied, the types of infections captured and in the definitions and terminology used to describe the results. We could not find definitive evidence that the incidence of MRSA infections in U.S. community or facilities is decreasing significantly. Of concern are recent data reported to the National Healthcare Safety Network (NHSN) on MRSA bloodstream infections which indicate that by the end of 2015 there had been little change in the average facility Standardized Infection Ratio (0.988), compared to a 2010-2011 baseline and is significantly increased compared to the previous year. This is in contradistinction to the recent Veterans Administration study which reported over an 80% reduction in MRSA infections. However, this discrepancy may be due to the inability to reconcile the baselines of the two data sets; and the observed increase may be artifactual due to aberrations in the NHSN tracking system. Our review supports the need for implementation of a comprehensive tracking and monitoring system involving all types of healthcare facilities for multi-drug resistant organisms, along with concomitant funding for both staff and infrastructure. Without such a system, determining the effectiveness of interventions such as antibiotic stewardship and chlorhexidine bathing will be hindered
SR-A ligand and M-CSF dynamically regulate SR-A expression and function in primary macrophages via p38 MAPK activation
<p>Abstract</p> <p>Background</p> <p>Inflammation is characterized by dynamic changes in the expression of cytokines, such as M-CSF, and modifications of lipids and proteins that result in the formation of ligands for Class A Scavenger Receptors (SR-A). These changes are associated with altered SR-A expression in macrophages; however, the intracellular signal pathways involved and the extent to which SR-A ligands regulate SR-A expression are not well defined. To address these questions, SR-A expression and function were examined in resident mouse peritoneal macrophages incubated with M-CSF or the selective SR-A ligand acetylated-LDL (AcLDL).</p> <p>Results</p> <p>M-CSF increased SR-A expression and function, and required the specific activation of p38 MAPK, but not ERK1/2 or JNK. Increased SR-A expression and function returned to basal levels 72 hours after removing M-CSF. We next determined whether prolonged incubation of macrophages with SR-A ligand alters SR-A expression. In contrast to most receptors, which are down-regulated by chronic exposure to ligand, SR-A expression was reversibly increased by incubating macrophages with AcLDL. AcLDL activated p38 in wild-type macrophages but not in SR-A-/- macrophages, and p38 activation was specifically required for AcLDL-induced SR-A expression.</p> <p>Conclusions</p> <p>These results demonstrate that in resident macrophages SR-A expression and function can be dynamically regulated by changes in the macrophage microenvironment that are typical of inflammatory processes. In particular, our results indicate a previously unrecognized role for ligand binding to SR-A in up-regulating SR-A expression and activating p38 MAPK. In this way, SR-A may modulate inflammatory responses by enhancing macrophage uptake of modified protein/lipid, bacteria, and cell debris; and by regulating the production of inflammatory cytokines, growth factors, and proteolytic enzymes.</p
Questionable Validity of the Catheter-associated Urinary Tract Infection Metric Used for Value-based Purchasing
Catheter-associated urinary tract infections (CAUTIs) occur in 290,000 US hospital patients annually, with an estimated cost of $290 million. Two different measurement systems are being used to track the US health care system\u27s performance in lowering the rate of CAUTIs. Since 2010, the Agency for Healthcare Research and Quality (AHRQ) metric has shown a 28.2% decrease in CAUTI, whereas the Centers for Disease Control and Prevention metric has shown a 3%-6% increase in CAUTI since 2009. Differences in data acquisition and the definition of the denominator may explain this discrepancy. The AHRQ metric analyzes chart-audited data and reflects both catheter use and care. The Centers for Disease Control and Prevention metric analyzes self-reported data and primarily reflects catheter care. Because analysis of the AHRQ metric showed a progressive change in performance over time and the scientific literature supports the importance of catheter use in the prevention of CAUTI, it is suggested that risk-adjusted catheter-use data be incorporated into metrics that are used for determining facility performance and for value-based purchasing initiatives
The Use of Surveillance and Preventative Measures for Methicillin-resistant Staphylococcus Aureus Infections in Surgical Patients
The Agency for Healthcare Research & Quality (AHRQ) found that Methicillin-resistant Staphylococcus aureus (MRSA) is associated with up to 375,000 infections and 23,000 deaths in the United States. It is a major cause of surgical site infections, with a higher mortality and longer duration of care than Methicillin-sensitive Staphylococcus aureus. A multifactorial bundled approach is needed to control this epidemic, with single interventions unlikely to have a significant impact on attenuating MRSA infection rates.Active surveillance has been studied in a wide range of surgical patients, including surgical intensive care and non-intensive care units; cardiac, vascular, orthopedic, obstetric, head and neck cancer and gastrostomy patients. There is sufficient evidence demonstrating a beneficial effect of surveillance and eradication prior to surgery to recommend its use on an expanded basis.Studies on MRSA surveillance in surgical patients that were published over the last 10 years were reviewed. In at least five of these studies, the MRSA colonization status of patients was reported to be a factor in preoperative antibiotic selection, with the modification of treatment regiments including the switching to vancomycin or teicoplanin in MRSA positive preoperative patients. Several authors also used decolonization protocols on all preoperative patients but used surveillance to determine the duration of the decolonization.Universal decolonization of all patients, regardless of MRSA status has been advocated as an alternative prevention protocol in which surveillance is not utilized. Concern exists regarding antimicrobial stewardship. The daily and universal use of intranasal antibiotics and/or antiseptic washes may encourage the promotion of bacterial resistance and provide a competitive advantage to other more lethal organisms.Decolonization protocols which indiscriminately neutralize all bacteria may not be the best approach. If a patient\u27s microbiome is markedly challenged with antimicrobials, rebuilding it with replacement commensal bacteria may become a future therapy.Preoperative MRSA surveillance allows the selection of appropriate prophylactic antibiotics, the use of extended decolonization protocols in positive patients, and provides needed data for epidemiological studies
Criterios de reparación en las victimas del conflicto armado
Colombia durante décadas, ha sido un pueblo donde ha imperado la violencia en zonas rurales y campesinas del país, generando así un gran número de víctimas. Esto ha despertado alertas en el Estado colombiano y ha obligado que se establezcan medidas que reparen los daños causados encaminado hacia una trasformación social. La viable ocurrencia de una transgresión de los derechos por parte del legislador, al quizás negar el reconocimiento en la calidad de una víctima bien sea a los mismos combatientes y a sus familias, la constante limitación del acceso a garantías de reparación y no repetición, es el hipotético paso a partir del cual se enfocan las siguientes observaciones que en este texto se exhiben.Universidad Libre de Colombia - Facultad de Derecho - Especialización en Derecho AdministrativoColombia for decades has been a country where violence by armed revolutionary groups outside the law has prevailed, which has as its nucleus the rural and peasant areas of the country, thus generating a large number of victims. This has raised alerts in the Colombian State and has forced the establishment of measures to repair the damage caused to the victims, aimed at a social transformation.
