Frontline pembrolizumab monotherapy for metastatic non-small cell lung cancer with PD-L1 expression ≥50%: real-world outcomes in a US community oncology setting.

Background: This study investigated real-world time on treatment (rwToT) and overall survival (OS) for patients with metastatic non-small cell lung cancer (mNSCLC) who initiated first-line (1L) pembrolizumab monotherapy. We also explored discontinuation reasons and subsequent treatments, stratified by number of cycles among those who completed ≥17 cycles of 1L pembrolizumab. Methods: Patients with mNSCLC without actionable genetic aberrations, Eastern Cooperative Oncology Group performance status (ECOG PS) 0-2 and unknown, and PD-L1 TPS ≥ 50% starting 1L pembrolizumab monotherapy between 24-Oct-2016 and 31-Dec-2018 within The US Oncology Network were identified retrospectively and evaluated using structured data, with a data cutoff of 30-Sep-2021. Patient characteristics and disposition were summarized using descriptive statistics. OS and rwToT were evaluated using Kaplan-Meier method for all ECOG PS and PS 0-1. A subgroup of patients who completed ≥17 cycles were evaluated using supplemental chart review data to discern reasons for discontinuation. Results: Of the 505 patients with mNSCLC with PD-L1 TPS ≥50%, 61% had ECOG PS 0-1, 23% had ECOG PS 2, and 65% had nonsquamous histology. Median rwToT and OS of pembrolizumab were 7.0 (95% CI, 6.0-8.4) months and 24.5 (95% CI, 20.1-29.3) months, respectively. In the subgroup with ECOG PS 0-1, they were 7.6 months (95% CI, 6.2-9.2) and 28.8 months (95% CI, 22.4-37.5), respectively. Of the 103 patients who completed ≥17 cycles, 57 (55.3%) patients received 17 - 34 cycles and 46 (44.7%) patients received ≥35 cycles. Approximately 7.7% of the study population received pembrolizumab beyond 35 cycles. Most common reasons for discontinuation were disease progression (38.6%) and toxicity (19.3%) among patients who received 17-34 cycles of pembrolizumab, and disease progression (13.0%) and completion of therapy (10.9%) among patients who received ≥35 cycles. Conclusion: Consistent with findings from KEYNOTE-024 and other real-world studies, this study demonstrates the long-term effectiveness of pembrolizumab monotherapy as 1L treatment for mNSCLC with PD-L1 TPS ≥50%. Among patients who completed ≥17 cycles, nearly half completed ≥35 cycles. Disease progression and toxicity were the most common reasons for discontinuation among patients who received 17-34 cycles of pembrolizumab. Reasons for discontinuation beyond 35 cycles need further exploration.

Acute Kidney Injury In Hospitalized Covid-19 Patients: A Retrospective Observational Study.

Background: Published studies have reported that acute kidney injury (AKI) and other kidney related manifestations are associated with COVID-19 and linked with poor outcome. This study aimed to determine the incidence, risk factors and outcomes of AKI in hospitalized COVID-19 patients. Methods: This retrospective study of 154 patients involved retrieving data from hospital records confirm COVID-19 infection admitted to the Northwest General Hospital & Research Center, Peshawar from 1st April to 31st July 2020. AKI was defined using kidney disease. Improving Global Outcomes (KDIGO)" guidelines. Results: Incidence of AKI was 37.01%. Age, gender, intensive care (ICU) requirement, number of comorbid, diabetes mellitus, coronary artery disease, chronic kidney disease, chronic obstructive airway disease (COAD), arrhythmias among comorbid and fever and shortness of breath among symptoms were found to be significantly differed between AKI and non-AKI patients. Numerous differences of laboratory results such as serum sodium, potassium, total leukocyte count, absolute lymphocyte count and platelets between both groups were observed (p<0.05). Inflammatory markers including lactate dehydrogenase (LDH), ferritin, d-dimer and C-reactive protein (CRP) were significantly raised in AKI group. Overall mortality was observed to be 38 (24.7%). Moreover, age, ICU requirement; COAD, creatinine, serum sodium, inflammatory markers (LDH, ferritin, d-dimers and CRP), total leukocyte count, absolute lymphocyte count, platelets and support requirement were significantly differed between survivors and non-survivors. Mortality was significantly higher among AKI group, i.e., 52.6% compared to 8.2% in non-AKI group (p<0.001). Conclusion: AKI is common among hospitalized COVID-19 patients and is associated with mortality. In all, AKI patients less than half of the patients survived.

Intimate-partner violence and its association with symptoms of depression, perceived health, and quality of life in the Himalayan Mountain Villages of Gilgit Baltistan.

STUDY OBJECTIVES: We aimed to estimate the prevalence of intimate partner violence (IPV) and associated risk factors in married women in rural villages of Gilgit Baltistan in Pakistan. METHODS: A cross-sectional design to assess the magnitude and factors associated with IPV in a random sample of 789 married women aged 18-49 years. A World Health Organization screening instrument was used to assess the presence of IPV in the previous 12 months. A locally validated instrument was adopted to identify self-reported symptoms of major depression according to the DSM IV. Trained nurses obtained socio-demographic and reproductive history through structured interviews. Bivariate and multivariable logistic regression analyses were used to estimate prevalence and identify significant predictors of IPV. RESULTS: The mean age of the participants was 38.3 years (SD: ±12.8). The prevalence of IPV in women was 22.8% (95% Confidence Interval: 20.0-25.9), 18.5% in pregnant women (95% CI: 11.7-27.9) and significantly associated with depression in 55.1% of IPV cases. Husband education level (college/higher) (Adjusted Odds Ratio: 0.40; 95%CI: 0.22-0.70) and high household income (AOR: 0.44; 95% CI: 0.29-0.68) were protective against IPV. Increase in age (AOR;1.02; 95% CI: 1.01-1.02) and poor relationship with mother-in-law increased the risk of IPV (AOR = 2.85; 95% CI: 1.90-4.28). IPV was positively associated with symptoms of depression (AOR = 1.97; 95% CI:1.39-2.77), poor perceived quality of life (AOR = 3.54; 95% CI: 1.90-6.58) and poor health (AOR = 2.74; 95% CI: 1.92-3.92). CONCLUSION: IPV is substantial public health burden significantly associated with depressive symptoms, poor perceived health and the quality of life.

Coding-Driven Changes In Measured Risk In Accountable Care Organizations.

Claims data, which form the foundation of risk adjustment in payment for health care services, may reflect efforts to capture more-or more severe-clinical conditions rather than true changes in health status. This can distort payments. We quantify this in the context of Medicare's accountable care organization (ACO) program by comparing risk scores derived from two different measurement approaches. One approach uses diagnoses coded on claims based on Centers for Medicare and Medicaid Services Hierarchical Condition Categories (HCC), and the other uses self-reported, survey-based health data from the Consumer Assessment of Healthcare Providers and Systems (CAHPS). During 2013-16 HCC-based risk scores grew faster than CAHPS-based risk scores (2.1 percent versus 0.3 percent annually), and the gap in HCC- and CAHPS-based risk score growth varied widely across ACOs. The average gap in risk score growth appears to be the result primarily of HCC coding practices rather than poor performance of the CAHPS model, suggesting that coding practices (not necessarily driven by ACO contracts) may account for most of the observed risk score growth for ACO beneficiaries.

Heavy metals immobilization and improvement in maize (Zea mays L.) growth amended with biochar and compost.

Soil with heavy metals contamination, mainly lead (Pb), cadmium (Cd), and chromium (Cr) is a progressively worldwide alarming environmental problem. Recently, biochar has been used as a soil amendment to remediate contaminated soils, but little work has been done to compare with other organic amendments like compost. We investigated biochar and compost's comparative effect on Pb, Cd, and Cr immobilization in soil, photosynthesis, and growth of maize plants. Ten kg soil was placed in pots and were spiked with Pb, Cd, and Cr at concentrations 20, 10, 20 mg kg-1. The biochar and compost treatments included 0, 0.5, 1, 2, and 4% were separately applied to the soil. The crop from pots was harvested after 60 days. The results show that the highest reduction of AB-DTPA extractable Pb, Cd, and Cr in soil was 79%, 61% and 78% with 4% biochar, followed by 61%, 43% and 60% with 4% compost compared to the control, respectively. Similarly, the highest reduction in shoot Pb, Cd, and Cr concentration was 71%, 63% and 78%with 4% biochar, followed by 50%, 50% and 71% with 4% compost than the control, respectively. The maximum increase in shoot and dry root weight, total chlorophyll contents, and gas exchange characteristics were recorded with 4% biochar, followed by 4% compost than the control. The maximum increase in soil organic matter and total nitrogen (N) was recorded at 4% biochar application while available phosphorus and potassium in the soil at 4% compost application. It is concluded that both biochar and compost decreased heavy metals availability in the soil, reducing toxicity in the plant. However, biochar was most effective in reducing heavy metals content in soil and plant compared to compost. In the future, more low-cost, eco-friendly soil remediation methods should be developed for better soil health and plant productivity.

Integrated control of dry root rot of chickpea caused by Rhizoctoniabataticola under the natural field condition.

The study investigated the effect of three fungicides Bavistin®, Aliette®, and Biomagic® at the rate of 2 g/L were tested In vitro and In vivo to control dry root rot and their impact on yield were evaluated at the rate of 4 g/L against R. bataticola while varieties used were Karak-1, Karak-2, Karak-3, and Sheenghar. Disease severity was recorded lowest (19 %) and highest yield (1467 Kg/ha), plant height (47.5 cm), number of pods/plant (15.0) and number of grain/pods (1.66) were recorded in cultivar Karak-1. Among the fungicides drugs, the Bavistin®, significantly reduced the disease severity (5 %) and Kg/ha), highest plant height (64.1 cm), highest grain yield (1488 Kg/ha), number of pods/plant (24.5) and number of grain/pods (2.25). It is concluded that the integrated use of Karak-1 and Bavistin®, fungicide drugs gave promising results for controlling dry root rot of chickpea, and increased plant height, number of pods/plant and number of grain/pods.

Association Between Clinical Practice Group Adherence to Quality Measures and Adverse Outcomes Among Adult Patients With Diabetes.

Importance: Clinical practice group performance on quality measures associated with chronic disease management has become central to reimbursement. Therefore, it is important to determine whether commonly used process and disease control measures for chronic conditions correlate with utilization-based outcomes, as they do in acute disease. Objective: To examine the associations among clinical practice group performance on diabetes quality measures, including process measures, disease control measures, and utilization-based outcomes. Design, Setting, and Participants: This retrospective, cross-sectional analysis examined commercial claims data from a national health insurance plan. A cohort of eligible beneficiaries with diabetes aged 18 to 65 years who were enrolled for at least 12 months from January 1, 2010, through December 31, 2014, was defined. Eligible beneficiaries were attributed to a clinical practice group based on the plurality of their primary care or endocrinology office visits. Data were analyzed from October 1, 2018, through April 30, 2019. Main Outcomes and Measures: For each clinical practice group, performance on current diabetes quality measures included 3 process measures (2 testing measures [hemoglobin A1c {HbA1c} and low-density lipoprotein {LDL} testing] and 1 drug use measure [statin use]) and 2 disease control measures (HbA1c <8% and LDL level <100 mg/dL). The rates of utilization-based outcomes, including hospitalization for diabetes and major adverse cardiovascular events (MACEs), were also measured. Results: In this cohort of 652 258 beneficiaries with diabetes from 886 clinical practice groups, 42.9% were aged 51 to 60 years, and 52.6% were men. Beneficiaries lived in areas that were predominantly white (68.1%). At the clinical practice group level, except for high correlation between the 2 testing measures, correlations among different quality measures were weak (r range, 0.010-0.244). Rate of HbA1c of less than 8% had the strongest correlation with hospitalization for MACE (r = -0.046; P = .03) and diabetes (r = -0.109; P < .001). Rates of HbA1c control at the clinical practice group level were not significantly associated with likelihood of hospitalization at the individual level. Performance on the process and disease control measures together explained 3.9% of the variation in the likelihood of hospitalization for a MACE or diabetes at the individual level. Conclusions and Relevance: In this study, performance on utilization-based measures-intended to reflect the quality of chronic disease management-was only weakly associated with direct measures of chronic disease management, namely, disease control measures. This correlation should be considered when determining the degree of financial emphasis to place on hospitalization rates as a measure of quality in treatment of chronic diseases.

Pros and Cons of Aspirin Prophylaxis for Prevention of Cardiovascular Events in Kidney Transplantation and Review of Evidence.

Kidney transplant recipients have traditional and nontraditional risk factors which can lead to coronary artery disease and sudden death with a functional graft loss. Aspirin has been used traditionally for prevention of cardiovascular and cerebrovascular accidents. It has beneficial effects in secondary prevention of cardiovascular events in general population. Its use for primary prophylaxis is still disputed. Bleeding and theoretical risk of nephrotoxicity are the major concerns about its use. The data on aspirin in kidney transplant population is sparse. This review will focus on various pros and cons of aspirin use for prevention of cardiovascular events in kidney transplant recipients and a way forward.

Prevalence of Diabetes Type 2 in Hepatitis C Infected Patients in Kpk, Pakistan.

Hepatitis C (HCV) and diabetes mellitus are the two main health concerns that cause devastating health and financial worries worldwide. It has been observed in the past that both diseases have a high correlation that might be due to the abnormal conditions of the liver. But the mechanism of the prevalence of diabetes in patients with chronic HCV infection still remains unclear. In our study, we have investigated T2DM in the male and female patients at Lady Reading Hospital (LRH), Peshawar. The blood samples of both in- and outpatients were analysed in the PCR laboratories of LRH from December 2014 to April 2015. Great prevalence of diabetes in hepatitis C infected male and female patients was observed during this study. The data were collected from the patients through a preplanned questionnaire that included name of the patient, HCV, being diabetic, age, gender, location, educational background, family history of the disease, other diseases, and any treatments if taken. The results of our study have found 26.42% prevalence of T2DM in HCV infected patients. So we conclude that HCV infection may be one of the reasons that could lead to T2DM.

Validation of a Cardiovascular Disease Policy Microsimulation Model Using Both Survival and Receiver Operating Characteristic Curves.

BACKGROUND: Despite some advances, cardiovascular disease (CVD) remains the leading cause of death and healthcare costs in the United States. We therefore developed a comprehensive CVD policy simulation model that identifies cost-effective approaches for reducing CVD burden. This paper aims to: 1) describe our model in detail; and 2) perform model validation analyses. METHODS: The model simulates 1,000,000 adults (ages 35 to 80 years) using a variety of CVD-related epidemiological data, including previously calibrated Framingham-based risk scores for coronary heart disease and stroke. We validated our microsimulation model using recent National Health and Nutrition Examination Survey (NHANES) data, with baseline values collected in 1999-2000 and cause-specific mortality follow-up through 2011. Model-based (simulated) results were compared to observed all-cause and CVD-specific mortality data (from NHANES) for the same starting population using survival curves and, in a method not typically used for disease model validation, receiver operating characteristic (ROC) curves. RESULTS: Observed 10-year all-cause mortality in NHANES v. the simulation model was 11.2% (95% CI, 10.3% to 12.2%) v. 10.9%; corresponding results for CVD mortality were 2.2% (1.8% to 2.7%) v. 2.6%. Areas under the ROC curves for model-predicted 10-year all-cause and CVD mortality risks were 0.83 (0.81 to 0.85) and 0.84 (0.81 to 0.88), respectively; corresponding results for 5-year risks were 0.80 (0.77 to 0.83) and 0.81 (0.75 to 0.87), respectively. LIMITATIONS: The model is limited by the uncertainties in the data used to estimate its input parameters. Additionally, our validation analyses did not include non-fatal CVD outcomes due to NHANES data limitations. CONCLUSIONS: The simulation model performed well in matching to observed nationally representative longitudinal mortality data. ROC curve analysis, which has been traditionally used for risk prediction models, can also be used to assess discrimination for disease simulation models.

Cardiometabolic risk in a population of older adults with multiple co-morbidities in rural south africa: the HAALSI (Health and Aging in Africa: longitudinal studies of INDEPTH communities) study.

BACKGROUND: A consequence of the widespread uptake of anti-retroviral therapy (ART) is that the older South African population will experience an increase in life expectancy, increasing their risk for cardiometabolic diseases (CMD), and its risk factors. The long-term interactions between HIV infection, treatment, and CMD remain to be elucidated in the African population. The HAALSI cohort was established to investigate the impact of these interactions on CMD morbidity and mortality among middle-aged and older adults. METHODS: We recruited randomly selected adults aged 40 or older residing in the rural Agincourt sub-district in Mpumalanga Province. In-person interviews were conducted to collect baseline household and socioeconomic data, self-reported health, anthropometric measures, blood pressure, high-sensitivity C-reactive protein (hsCRP), HbA1c, HIV-status, and point-of-care glucose and lipid levels. RESULTS: Five thousand fifty nine persons (46.4% male) were enrolled with a mean age of 61.7 ± 13.06 years. Waist-to-hip ratio was high for men and women (0.92 ± 0.08 vs. 0.89 ± 0.08), with 70% of women and 44% of men being overweight or obese. Blood pressure was similar for men and women with a combined hypertension prevalence of 58.4% and statistically significant increases were observed with increasing age. High total cholesterol prevalence in women was twice that observed for men (8.5 vs. 4.1%). The prevalence of self-reported CMD conditions was higher among women, except for myocardial infarction, and women had a statistically significantly higher prevalence of angina (10.82 vs. 6.97%) using Rose Criteria. The HIV- persons were significantly more likely to have hypertension, diabetes, or be overweight or obese than HIV+ persons. Approximately 56% of the cohort had at least 2 measured or self-reported clinical co-morbidities, with HIV+ persons having a consistently lower prevalence of co-morbidities compared to those without HIV. Absolute 10-year risk cardiovascular risk scores ranged from 7.7-9.7% for women and from 12.5-15.3% for men, depending on the risk score equations used. CONCLUSIONS: This cohort has high CMD risk based on both traditional risk factors and novel markers like hsCRP. Longitudinal follow-up of the cohort will allow us to determine the long-term impact of increased lifespan in a population with both high HIV infection and CMD risk.

Comparison of Nonblood-Based and Blood-Based Total CV Risk Scores in Global Populations.

BACKGROUND: Cost-effective primary prevention of cardiovascular disease (CVD) in low- and middle-income countries requires accurate risk assessment. Laboratory-based risk tools currently used in high-income countries are relatively expensive and impractical in many settings due to lack of facilities. OBJECTIVES: This study sought to assess the correlation between a non-laboratory-based risk tool and 4 commonly used, laboratory-based risk scores in 7 countries representing nearly one-half of the world's population. METHODS: We calculated 10-year CVD risk scores for 47,466 persons with cross-sectional data collected from 16 different cohorts in 9 countries. The performance of the non-laboratory-based risk score was compared with 4 laboratory-based risk scores: Pooled Cohort Risk Equations (ASCVD [Atherosclerotic Cardiovascular Disease]), Framingham, and SCORE (Systematic Coronary Risk Evaluation) for high- and low-risk countries. Rankings of each score were compared using Spearman rank correlations. Based on these correlations, we measured concordance between individual absolute CVD risk as measured by the Harvard NHANES (National Health and Nutrition Examination Survey) risk score, and the 4 laboratory-based risk scores, using both the conventional Framingham risk thresholds of >20% and the recent ASCVD guideline threshold of >7.5%. RESULTS: The aggregate Spearman rank correlations between the non-laboratory-based risk score and the laboratory-based scores ranged from 0.915 to 0.979 for women and from 0.923 to 0.970 for men. When applying the conventional Framingham risk threshold of >20% over 10 years, 92.7% to 96.0% of women and 88.3% to 92.8% of men were equivalently characterized as "high" or "low" risk. Applying the recent ASCVD guidelines risk threshold of >7.5% resulted in risk characterization agreement for women ranging from 88.1% to 94.4% and from 89.0% to 93.7% for men. CONCLUSIONS: The correlation between non-laboratory-based and laboratory-based risk scores is very high for both men and women. Potentially large numbers of high-risk individuals could be detected with relatively simple tools.

Factors Associated With Poor Outcome in Childhood Swimming Pool Submersions.

OBJECTIVES: The aims of the study were to determine factors associated with poor outcome in childhood swimming pool submersions and to study the association of bystander resuscitation with clinical outcome. METHODS: This was a retrospective study of swimming pool submersion victims younger than 18 years in a metropolitan area from 2003 to 2007. Submersion, prehospital, and victim data were obtained from hospital, Emergency Medical Services, and fatality records. Outcome based on survival at hospital discharge was favorable (baseline/mild impairment) or poor (death/severe impairment). Logistic regression determined factors associated with poor outcome. RESULTS: There were 260 submersions. Outcomes were available for 211 (81%). The median age was 4 years; 68% were males. Most incidents occurred at single residential pools (48%) and multiresidential pools (35%). Mortality was 23%; 75% had favorable outcomes. Favorable outcomes occurred in 8.6% (3/35) of victims with absent pulse at the scene. Descriptive analyses revealed significant differences in submersions that occurred on weekdays, during the summer, submersions lasting 5 minutes or more, with on-scene apnea or cardiac arrest needing cardiopulmonary resuscitation, rescuer type, and transfer to tertiary care. Logistic regression revealed that poor outcome was significantly associated with prolonged submersions and those that occurred on a weekday. Furthermore, hospitalization reduced the odds of a poor outcome by 81% when compared with victims who were not hospitalized. Bystander resuscitation was not significantly associated with outcome. CONCLUSIONS: Childhood swimming pool submersions, which occur on weekdays and with prolonged submersion times, are associated with poor outcome. Bystander resuscitation is not significantly associated with outcome.

Pediatricians Support Initiation of Asthma Controller Medications in the Emergency Department: A National Survey.

OBJECTIVES: Although National Asthma Guidelines recommend that emergency department (ED) physicians consider initiating controller medications, research suggests that this practice occurs infrequently. The goal of this study was to assess primary care pediatricians' (PCP) beliefs and attitudes regarding ED initiation of controller medications for children with persistent asthma symptoms. METHODS: This was a cross-sectional mail survey of a randomly selected national sample of pediatricians from the American Academy of Pediatrics. The survey posed questions regarding beliefs, barriers, and support for national guideline recommendations. RESULTS: Eight hundred eighty-six (44.3%) of 2000 subjects responded. Five hundred seventy-two (64.5%) respondents met eligibility for analysis. When presented with a vignette of a child with persistent asthma, 476 (83%) of PCPs felt it was appropriate for the ED physician to initiate controller medications. Most (80%) PCPs supported the national guideline recommendation, although a similar proportion reported they have never or rarely experienced this practice before. Only 11% opposed the practice in all circumstances. Beliefs supporting this practice included the following: opportunity to capture patients lost to follow-up (85%), reinforcement of daily use of controller medications (83%), and controller medication may shorten an acute exacerbation (53%). Barriers included lack of time for education in ED (65%), reinforcement of ED use for primary care (64%), lack of PCP communication (62%), and inability to assess severity appropriately (41%). Most (90%) PCPs expect communication from the ED provider. CONCLUSIONS: A majority of pediatricians support the practice of ED physicians initiating controller medication during an acute visit for asthma. Communication with the PCP, appropriate screening of severity, and education about controller medications were important considerations expressed by these providers.

Referral outcomes of individuals identified at high risk of cardiovascular disease by community health workers in Bangladesh, Guatemala, Mexico, and South Africa.

BACKGROUND: We have found that community health workers (CHWs) with appropriate training are able to accurately identify people at high cardiovascular disease (CVD) risk in the community who would benefit from the introduction of preventative management, in Bangladesh, Guatemala, Mexico, and South Africa. This paper examines the attendance pattern for those individuals who were so identified and referred to a health care facility for further assessment and management. DESIGN: Patient records from the health centres in each site were reviewed for data on diagnoses made and treatment commenced. Reasons for non-attendance were sought from participants who had not attended after being referred. Qualitative data were collected from study coordinators regarding their experiences in obtaining the records and conducting the record reviews. The perspectives of CHWs and community members, who were screened, were also obtained. RESULTS: Thirty-seven percent (96/263) of those referred attended follow-up: 36 of 52 (69%) were urgent and 60 of 211 (28.4%) were non-urgent referrals. A diagnosis of hypertension (HTN) was made in 69% of urgent referrals and 37% of non-urgent referrals with treatment instituted in all cases. Reasons for non-attendance included limited self-perception of risk, associated costs, health system obstacles, and lack of trust in CHWs to conduct CVD risk assessments and to refer community members into the health system. CONCLUSIONS: The existing barriers to referral in the health care systems negatively impact the gains to be had through screening by training CHWs in the use of a simple risk assessment tool. The new diagnoses of HTN and commencement on treatment in those that attended referrals underscores the value of having persons at the highest risk identified in the community setting and referred to a clinic for further evaluation and treatment.

A novel briefing checklist at shift handoff in an emergency department improves situational awareness and safety event identification.

OBJECTIVES: Emergency department (ED) shift handoffs are sources of potential medical error, delays in care, and medicolegal liabilities. Few handoff studies exist in the ED literature. We aimed to describe the implementation of a standardized checklist for improving situational awareness during physician handoffs in a pediatric ED. METHODS: This is a descriptive observational study in a large academic pediatric ED. Checklists were evaluated for rates of use, completion, and identification of potential safety events. We defined a complete checklist as 80% or more of items checked. A user perception survey was used. After 1 year, all checklist users (residents, fellows, faculty, and charge nurses with ED experience before and after checklist implementation) were anonymously surveyed to assess the checklist's usability, perceived contributions to Institute of Medicine quality domains, and situational awareness. The electronically administered survey used Likert frequency scales. RESULTS: Of 732 handoffs, 98% used the checklist, and 89% were complete. A mean of 1.7 potential safety events were identified per handoff. The most frequent potential safety events were identification of intensive care unit-level patients in the ED (48%), equipment problems (46%), staffing issues (21%), and intensive care unit-level patients in transport (16%). Eighty-one subjects (88%) responded to the survey. The users agreed that the checklist promoted better communication, safety, efficiency, effective care, and situational awareness. CONCLUSIONS: The Physician Active Shift Signout in the Emergency Department briefing checklist was used often and at a high completion rate, frequently identifying potential safety events. The users found that it improved the quality of care and team communication. Future studies on outcomes and processes are needed.

Clinical efficacy of sevelamer hydrochloride in patients with end-stage renal disease: a retrospective study.

INTRODUCTION: Sevelamer hydrochloride (Renagel) is frequently used as a second-line phosphate binder in patients on renal replacement therapy. Many studies have shown that sevelamer can improve vascular calcification, serum uric acid and low-density lipoprotein (LDL) cholesterol levels. The main objectives of this study were to assess the efficacy of sevelamer against calcium-based phosphate binders, as well as its tolerability and side-effect profile. METHODS: This was a retrospective study that included all patients on renal replacement therapy (between 2008 and 2011) who had previously received calcium-based binders for ≥ 6 months and were subsequently switched to sevelamer. Data collected from the patients' medical records included demographics, as well as renal parameters three months prior to sevelamer treatment, and at three and six months post treatment. The study excluded patients on multiple, concomitant phosphate binders or with functioning renal transplants, and those who were noncompliant or had inadequate follow-up blood investigations. RESULTS: A total of 39 patients were included in the study. No major side effects were reported by any of the patients. There were improvements in calcium, phosphate, uric acid and LDL cholesterol levels at three and six months post-sevelamer treatment. CONCLUSION: We found sevelamer to be superior to calcium-based phosphate binders in reducing serum calcium, phosphate, uric acid and LDL cholesterol levels in our patient population with advanced renal bone disease. Sevelamer also appears to be well tolerated with no significant side effects.

Social capital and disaster preparedness among low income Mexican Americans in a disaster prone area.

Examination of social capital and its relationship to disaster preparedness has grown in prominence partially due to world-wide need to effectively respond to terrorist attacks, viral epidemics, or natural disasters. Recent studies suggested that social capital may be related to a community's ability to plan for and respond to such disasters. Few studies, however, have examined social capital constructs among low income populations living in disaster prone areas and accounted for the influence of social capital at the individual and community level. We examined social capital as measured by perceived fairness, perceived civic trust, perceived reciprocity and group membership. We undertook a multistage random cluster survey in three coastal counties in Texas (U.S.) noted for their high levels of poverty. Individuals from 3088 households provided data on social capital, socioeconomic and demographic characteristics, and self-reported level of preparedness for a hurricane. We used multivariable logistic regression to test potential associations between social capital measures and disaster preparedness. After adjusting for age, gender, marital status, ethnicity, education, employment, household income, acculturation, self-reported health, special needs persons in household, household size, and distance to the shore we found a higher prevalence of preparedness among individuals who reported the highest perception of fairness [AOR = 3.12, 95% CI: (1.86, 5.21)] compared to those individuals who reported lowest perceptions of fairness. We also found a higher prevalence of preparedness [AOR = 2.06; 95% CI: (1.17, 3.62)] among individuals who reported highest perceptions of trust compared to individuals who reported lowest perceptions of trust. Perceived reciprocity and group membership were not associated with preparedness. These results extend previous findings on social capital and disaster preparedness and further characterize social capital's presence among a low income population living in a hurricane prone area.

Intention to comply with mandatory hurricane evacuation orders among persons living along a coastal area.

OBJECTIVES: We examined the intention to comply with mandatory hurricane evacuation orders among respondents living in coastal areas with pronounced poverty by demographic and location characteristics. METHODS: A 3-county door-to-door survey was conducted with 1 randomly selected resident per household. Households were selected using a 2-stage cluster sampling strategy and stratified by county. The final sample included 3088 households in 100 census tracts across 3 counties. RESULTS: Findings suggest that the majority of residents living in areas prone to hurricanes intend to comply with mandatory evacuation orders regardless of income level. Variation in intention to comply with mandatory evacuation orders is shown by age, gender, ethnicity, education, acculturation, county, and distance from shoreline. CONCLUSIONS: The demonstrated high intention to comply with evacuation orders in impoverished areas suggests a need for improved planning to evacuate the most vulnerable residents. Demographic and location characteristics associated with decreased intention to comply may be considered for targeting messages and education before disasters to modifying intentions and plans to evacuate.
