Characteristics of Medicaid Recipients Receiving Persistent Antipsychotic Polypharmacy.

Antipsychotic polypharmacy (APP) is a common strategy despite guidelines advising against this practice. This article seeks to quantify the prevalence and correlates of APP using Medicaid Analytic eXtract files from 2003 to 2004. Nineteen percent of Medicaid recipients who received an antipsychotic were treated with APP. Individuals who received APP were more likely to be white, male, disabled, between the ages of 18-29, diagnosed with a psychotic disorder, and diagnosed with a higher number of psychiatric conditions. Geographic variation in APP rates was also observed. Quality improvement initiatives may help reduce APP for medically vulnerable patients.

Cross-sectional survey in CKD patients across Europe describing the association between quality of life and anaemia.

BACKGROUND: Deteriorating renal function in chronic kidney disease (CKD) patients is commonly associated with reduced haemoglobin levels, adding to the already considerable humanistic burden of CKD. This analysis evaluated the impact of anaemia on disease burden in patients with CKD stages 3-4, and in those on dialysis. METHODS: This was a descriptive, cross-sectional analysis of European data from an Adelphi CKD Disease-Specific Programme. This programme collected data from patients and their treating nephrologists/endocrinologists; patient- and physician-reported data were matched for each patient. Health-related quality of life (HRQoL) data were obtained through patient completion of the EQ-5D, SF-12 and KDQOL-36. Additional information was obtained via physician reporting of patient symptoms, and patients' reports of impaired activity. Anaemia was defined by haemoglobin level and/or current use of erythropoiesis stimulating agents. RESULTS: Significant, but modest Spearman's rank correlations were observed between haemoglobin levels and extent of HRQoL impairment, regardless of instrument used (range 0.19-0.23; all P-values < 0.0001). When stratified by anaemia status, impairment was consistently lower for anaemic than non-anaemic CKD patients across measurement scales (e.g. EQ-5D index value [standard deviation {SD}] 0.72 [0.31] vs 0.83 [0.23], respectively; P < 0.0001). Physician-reported patient tiredness was associated with increased disease burden at all levels of CKD studied (total EQ-5D index value [SD] in patients reporting no tiredness vs tiredness 0.81 [0.26] vs 0.70 [0.30] respectively; P < 0.0001) with P < 0.0001 for no tiredness vs tiredness at all stages of CKD. The presence of anaemia was associated with impaired activity levels at CKD stages 3 (37.5 % vs 28.4 %, respectively; P = 0.0044) and 4 (48.1 % vs 39.9 %, respectively; P = 0.0292), and in patients on dialysis (52.0 % vs 45.0 %, respectively; P = 0.0732). CONCLUSIONS: The analysis found that CKD patients with anaemia typically had a lower HRQoL than those without anaemia. The impairment correlated with anaemia was more apparent in non-dialysis patients with CKD stages 3 or 4 than in those receiving dialysis. Coexisting CKD and anaemia may have an impact on patient HRQoL similar to other chronic conditions such as diabetes, epilepsy or certain forms of cancer.

Assessment and management of hypertension in transplant patients.

Hypertension in renal transplant recipients is common and ranges from 50% to 80% in adult recipients and from 47% to 82% in pediatric recipients. Cardiovascular morbidity and mortality and shortened allograft survival are important consequences of inadequate control of hypertension. In this review, we examine the epidemiology, pathophysiology, and management considerations of post-transplant hypertension. Donor and recipient factors, acute and chronic allograft injury, and immunosuppressive medications may each explain some of the pathophysiology of post-transplant hypertension. As observed in other patient cohorts, renal artery stenosis and adrenal causes of hypertension may be important contributing factors. Notably, BP treatment goals for renal transplant recipients remain an enigma because there are no adequate randomized controlled trials to support a benefit from targeting lower BP levels on graft and patient survival. The potential for drug-drug interactions and altered pharmacokinetics and pharmacodynamics of the different antihypertensive medications need to be carefully considered. To date, no specific antihypertensive medications have been shown to be more effective than others at improving either patient or graft survival. Identifying the underlying pathophysiology and subsequent individualization of treatment goals are important for improving long-term patient and graft outcomes in these patients.

Routine bioimpedance-derived volume assessment for all hypertensives: a new paradigm.

Hypertension is one of the most common worldwide diseases. Is linked with increased morbidity and mortality and amplified costs to society; in this context, preventing and treating hypertension is an imperative public health challenge. Unidentified, clinically unapparent volume expansion is an important cause for hypertension. Optimization of fluid status was associated with an improvement in BP control, a substantial regression of the left ventricular mass index, arterial stiffness and better survival rate in several cohorts. Clinical assessment of hydration status is an inaccurate clinical science. Bioimpedance provides a noninvasive and reliable, simple, reproducible technology for diagnosing subclinical fluid accumulation. Several small studies and a recent meta-analysis performed in patients with resistant hypertension reported an improved BP control in the impedance treated group compared with the group of patients treated as per clinical judgment alone. A combined approach (using both sphygmomanometers and bioimpedance) and individualized antihypertensive treatment in hypertensive's patients it seems probable to improve BP control and possibly end organ damage.

Assessment of arterial stiffness for clinical and epidemiological studies: methodological considerations for validation and entry into the European Renal and Cardiovascular Medicine registry.

Epidemiological studies have highlighted the role of arterial stiffness as a risk factor for development of cardiovascular (CV) diseases. Moreover, aortic stiffness has been shown to be a significant predictive factor of all-cause and CV mortality in different populations including patients with end-stage renal disease. Pulse-wave velocity (PWV) is the most widely used technique to assess arterial stiffness. Although PWV can be measured on any artery or between any arterial sites, only carotid-to-femoral PWV, representing stiffness of the aorta and iliofemoral axes, has been shown to have predictive value for morbidity and mortality. The several available commercial devices differ according to the type of signal (pressure, distension, flow) or by recording both sites simultaneously or using ECG synchronization. It is also possible to directly measure arterial diameter changes during the cardiac cycle and link them to local pulse-pressure changes, which provides the pressure-diameter relationship and stress-strain relationship if arterial wall thickness is also measured. These techniques are based on high-precision vascular echo tracking or magnetic resonance imaging and applanation tonometry. This paper summarizes the basic principles of arterial haemodynamics and various methodologies to assess stiffness and the latest consensus recommendations for clinical applications.

Cost-effectiveness of lanthanum carbonate versus sevelamer hydrochloride for the treatment of hyperphosphatemia in patients with end-stage renal disease: a US payer perspective.

OBJECTIVE: To assess the cost-effectiveness of lanthanum carbonate (LC) versus sevelamer hydrochloride (SH) as a treatment for hyperphosphatemia in end-stage renal disease (ESRD) patients. METHODS: A Markov model was developed to estimate health outcomes; quality-adjusted life years (QALYs) and life-years saved (LYS), as well as associated costs. The model incorporated patient-level data from a randomized head-to-head crossover study that compared the reduction of serum phosphorus using LC and SH for 4 weeks each. The model included patients previously treated with calcium-based binders. Both the intent-to-treat (ITT) population and the cohort of patients who completed treatment in both periods of the study (i.e., completer population) were assessed. The baseline risks of cardiovascular disease (CVD), all-cause mortalities for CVD, and non-CVD patients were derived from a large US renal database. Patient outcomes were modeled for 10 years, and incremental cost-effectiveness ratios (ICERs) were calculated for LC relative to SH. Deterministic and probabilistic sensitivity analyses (PSA) were performed to test the robustness of the base-case model. RESULTS: For the ITT population, the ICERs of LC versus SH were $24,724/QALY and $15,053/LYS, respectively (in US dollars). When the completer population was considered, the ICERs of LC versus SH were $15,285/QALY and $9,337/LYS (Table 2), respectively. The PSA indicated 61.9% and 85.8% probabilities for ITT and completer populations of LC being cost-effective at the $50,000/QALY willingness-to-pay threshold, respectively. CONCLUSION: LC is a cost-effective strategy compared with SH in the treatment of ESRD patients with hyperphosphatemia who were previously treated with calcium-based binders. Sensitivity analyses demonstrated the robustness of the pharmacoeconomic model.

Prevalence and management of anaemia in renal transplant recipients: data from ten European centres.

BACKGROUND: Although it is a known predictor of mortality, there is a relative lack of recent information about anaemia in kidney transplant recipients. Thus, we now report data about the prevalence and management of post-transplant anaemia (PTA) in Europe 5 years after the TRansplant European Survey on Anemia Management (TRESAM) study. METHODS: In a cross-sectional study enrolling the largest number of patients to date, data were obtained from 5,834 patients followed at 10 outpatient transplant clinics in four European countries using the American Society of Transplantation anaemia guideline. RESULTS: More than one third (42%) of the patients were anaemic. The haemoglobin (Hb) concentration was significantly correlated with the estimated glomerular filtration rate (eGFR) (r = 0.4, p < 0.001). In multivariate analysis, eGFR, serum ferritin, age, gender, time since transplantation and centres were independently and significantly associated with Hb. Only 24% of the patients who had a Hb concentration <110 g/l were treated with an erythropoiesis-stimulating agent. The prevalence of anaemia and also the use of erythropoiesis-stimulating agents were significantly different across the different centres, suggesting substantial practice variations. CONCLUSIONS: PTA is still common and under-treated. The prevalence and management of PTA have not changed substantially since the TRESAM survey.

An economic evaluation of sevelamer in patients new to dialysis.

OBJECTIVE: The overall objective of this study was to estimate the costs and outcomes associated with treatment with sevelamer for hyperphosphataemia compared with calcium-based binders. METHODS: Using published data on mortality and hospitalisation rates, a Markov model was developed to predict health outcomes and associated costs for the treatment of hyperphosphataemia using either sevelamer or calcium binders in chronic kidney disease patients who had recently started haemodialysis. Patient outcomes were modelled for 5 years, and incremental cost-effective ratios (ICERs) were calculated for sevelamer relative to calcium carbonate and calcium acetate binders. The perspective adopted was that of the UK National Health Service. RESULTS: The total 5-year discounted treatment cost for patients treated with sevelamer is pound 24,216, while for the calcium carbonate group total cost was pound 17,695. This is an incremental cost of pound 6521 per sevelamer-treated patient over 5 years. Patients receiving sevelamer can be expected to experience 2.70 quality-adjusted life years (QALYs) compared to 2.46 for those treated with calcium carbonate (i.e. an incremental gain of 0.24 QALYs). This results in an incremental cost per QALY of pound 27,120 and an incremental cost per life year gained of pound 15,508. Results were similar with calcium acetate. CONCLUSION: Together with the unique morbidity and mortality benefits, this study suggests that treatment with sevelamer confers clinical benefits with a modest investment of additional economic resources.

Sevelamer hydrochloride: a review of its use for hyperphosphataemia in patients with end-stage renal disease on haemodialysis.

Sevelamer (Renagel), an orally administered metal-free cationic hydrogel polymer/resin that binds dietary phosphate in the gastrointestinal (GI) tract, is approved for use in the US, Europe and several other countries for the treatment of hyperphosphataemia in adult patients with end-stage renal disease (ESRD) on haemodialysis or peritoneal dialysis.Clinical evidence shows that sevelamer was at least as effective as calcium acetate and calcium carbonate at controlling serum phosphorus, calcium-phosphorus product (Ca x P) and intact parathyroid hormone (iPTH) levels, but generally reduced serum calcium levels to a greater extent and was associated with a lower risk of hypercalcaemic episodes than calcium-based phosphate binders. Sevelamer appeared to slow the progression of cardiovascular calcification in patients with ESRD and also had a beneficial effect on serum low-density lipoprotein-cholesterol (LDL-C) levels. In patients receiving chronic haemodialysis, there was no between-group difference in all-cause mortality between sevelamer and calcium-based phosphate binder therapy in the primary efficacy analysis in the large (n >2100), 3-year DCOR trial; in the smaller (n = 109) nonblind RIND trial in patients new to dialysis, data suggest there is an overall survival benefit with sevelamer versus calcium-based phosphate binder treatment. The relative survival benefits and cost effectiveness of these phosphate binder therapies remains to be fully determined. Sevelamer treatment was generally as well tolerated as calcium acetate or calcium carbonate treatment. Overall, sevelamer is a valuable option for the management of hyperphosphataemia in patients with ESRD on haemodialysis.

DC Water and Sewer Authority and lead in drinking water: a case study in environmental health risk management.

In 2001, following a change in disinfection agent in anticipation of the Environment Protection Agency Disinfection Byproduct Rule, lead levels began rising in drinking water in Washington, District of Columbia, and in 2002, the DC Water and Sewer Authority was found to have exceeded the Environment Protection Agency lead action level, requiring compliance with a series of measures under the Lead and Copper Rule. In 2004, the issue became a public concern, drawing considerable media attention. The problem was eventually resolved through the application of orthophosphate but while it played out, the utility was forced to respond to a novel public health issue with few risk management options. This case study examines the lessons learned.
