Objective: To address gaps in the literature on healthcare resource utilization (HRU) and costs among patients with schizophrenia and prior hospitalization who transition from oral risperidone or paliperidone (oral ris/pali) to once-monthly paliperidone palmitate (PP1M) in a real-world setting by comparing treatment patterns, HRU, and costs 12-months pre- and post-transition to PP1M among Veterans Health Administration (VHA) patients affected by schizophrenia who have had ≥1 hospitalization. Methods: VHA patients with schizophrenia (aged ≥18 years) who initiated oral ris/pali, had ≥1 all-cause inpatient stay and transitioned to PP1M from January 2015 through March 2017 were included from the VHA database. The first transition date to PP1M was identified as the index date. Patients were required to have continuous health plan eligibility for 12 months pre- and post-PP1M. Outcomes were compared using the Wilcoxon signed-rank and McNemar’s test, as appropriate. Results: The study included 319 patients (mean [SD] age: 51.6 [4.2] years) during 12-months of baseline and follow-up. During pre-PP1M transition, 7.2% of the patients were adherent (proportion of days covered [PDC] ≥ 80%) to oral ris/pali. Post-PP1M transition, 27.6% of the patients were adherent to PP1M. Comparison of HRU outcomes from the pre- to post-PP1M transition revealed significantly lower all-cause inpatient stays (3.5 vs 1.4, p Conclusions: Transitioning from oral ris/pali to PP1M may significantly improve HRU and provide potential cost savings in VHA patients with schizophrenia and ≥1 prior hospitalization.

There is limited literature on treatment patterns, healthcare resource utilization (HRU), and costs among patients who transition from once-monthly paliperidone palmitate (PP1M) to once-every-3-month paliperidone palmitate (PP3M) in a real-world setting. Hence, this study compared treatment patterns, HRU, and costs 12-month pre- and post-PP3M transition among Veteran’s Health Administration (VHA) patients with schizophrenia. Patients with schizophrenia (aged ≥ 18 years) who initiated PP1M and transitioned per on-label criteria to PP3M (no treatment gap of > 45 days in PP1M during the 4 months prior, same dose strength of the last two PP1M claims, and appropriate dose conversion from last PP1M to first PP3M claim) from January 2015 to March 2017 were included from the VHA database. The first transition date to PP3M was identified as the index date. Patients were required to have 12-month pre- and post-PP3M continuous health plan eligibility. Outcomes were compared using the Wilcoxon-signed rank and McNemar’s test, appropriately. The study included 122 patients [mean (SD) age: 54 (13.7) years]. Pre- and post-PP3M transition, 64.8% and 61.5% of patients were adherent (proportion of days covered ≥ 80%) to PP1M and PP3M, respectively. Comparison of HRU outcomes pre- and post-PP3M transition exhibited lower all-cause outpatient (37.5 vs. 31.1, p

Factors underlying the selection of antipsychotics for patients with schizophrenia are poorly understood. This study investigated variables associated with initiation of treatment with the long-acting injectables paliperidone palmitate (LAI-PP) and aripiprazole LAI (LAI-AP) in Medicaid patients with schizophrenia. Adults with at least one medical or pharmacy claim for LAI-PP or LAI-AP from 1 January 2013 to 31 December 2016 were selected from the IBM® MarketScan® Medicaid Database. The date of the first LAI-PP or LAI-AP claim was the index date. Patients who had at least two medical claims, on different days, for a schizophrenia diagnosis and at least 12 months of continuous health plan enrollment prior to index date were included in the analysis. Multivariable logistic regression was performed to determine the factors associated with the initiation of LAI-PP versus LAI-AP. Of included patients, 5501 initiated LAI-PP and 1449 initiated LAI-AP. Patients more likely to initiate LAI-PP versus LAI-AP were older, male, or African American (all p

Much of the burden associated with schizophrenia is attributed to its early onset and chronic nature. Treatment with once monthly paliperidone palmitate (PP1M) is associated with lower healthcare utilization and better adherence as compared to oral atypical antipsychotics (OAAs). This study aimed to evaluate real-world effectiveness of PP1M and OAA therapies among US-based adult Medicaid patients with schizophrenia, overall and among young adults aged 18-35 years.Adult patients with a diagnosis of schizophrenia and at least two claims for PP1M or OAA between January 1, 2010 and December 31, 2014 were selected from the IBM Watson Health MarketScan Medicaid Database. Treatment patterns and healthcare resource utilization and costs were compared between PP1M and OAA treatment groups following inverse probability of treatment (IPT) weighting to adjust for potential differences. Utilization and cost outcomes were estimated using OLS and weighted Poisson regression models.After IPT weighting, the young adult PP1M and OAA cohorts were comprised of 3,095 and 3,155 patients, respectively. PP1M patients had a higher duration of continuous treatment exposure (168.2 vs 132.5 days, p = .004) and better adherence on the index medication (proportion of days covered ≥80%: 19.0% vs 17.1%, p .049). Young adults treated with PP1M were 37% less likely to have an all-cause inpatient admission (odds ratio [OR] = 0.63, 95% confidence interval [CI] = 0.53-0.74) and 33% less likely to have an ER visit (OR = 0.67, 95% CI = 0.55-0.81) compared to OAA young adult patients, but 27% more likely to have an all-cause outpatient office visit (OR = 1.27, 95% CI = 1.02-1.56). PP1M patients incurred significantly lower medical costs as compared to OAA patients.Medicaid patients with schizophrenia treated with PP1M have higher medication adherence and have fewer hospitalizations as compared to patients treated with OAAs. PP1M may lead to reduced healthcare utilization and improved clinical outcomes.

Objective: To compare rehospitalizations in patients with schizophrenia treated with paliperidone palmitate (PP1M) vs oral atypical antipsychotics (OAAs), with a focus on young adults (18–35 years)...

The objective was to assess the association of Medicaid coverage gaps with health care resource utilization (HRU) and costs of patients with schizophrenia. Patients with schizophrenia were identified from the Medicaid database. The beginning of the first eligible gap was defined as the index date. Per-patient per-month (PPPM) HRU and costs before versus after a gap were assessed, and the association between gap duration and PPPM HRU and costs was examined up to 12 months post index. Together with 95% confidence intervals, HRU differences were reported in rate ratios (RRs), and cost differences were reported in 2016 US dollars. A subgroup of males with substance use disorder (SUD; risk factors for incarceration) also was analyzed. Total PPPM health care costs increased significantly by $711.04 following a coverage gap (

Objectives: To compare comorbidity-related outcomes, adherence to antipsychotics (APs), healthcare resource utilization (HRU), and costs pre- and post-transition to once-every-3-months paliperidone palmitate (PP3M) in commercially-insured patients with schizophrenia. Methods: Adults with ≥1 claim for PP3M, ≥2 schizophrenia diagnoses, and adequate treatment with once-monthly paliperidone palmitate (PP1M; i.e. no gap of >45 days in PP1M coverage for ≥4 months, same PP1M dosage for the last two PP1M claims, and appropriate PP1M to PP3M dosing conversion) were selected from the IQVIA PharMetrics Plus database (May 2014–February 2018). Generalized estimating equation models adjusted for repeated measurements were used to compare patient characteristics, adherence to APs, HRU, and costs during the 6-month period pre- vs post-transition to PP3M. Results: Of 152 included patients, the mean age was 41.0 years and 36.2% were females. Post-PP3M transition, patients were less likely to have a claim with a diagnosis for substance-related and addictive disorders (odds ratio [OR] = 0.57), psychoses (OR = 0.57), diabetes without chronic complication (OR = 0.72), and drug abuse (OR = 0.64; all p p = .007), compared to the period pre-PP3M transition. There was no significant difference in HRU pre- vs post-transition. All-cause total (mean monthly cost difference [MMCD] = $242), pre-rebate pharmacy (MMCD = $65), and medical costs (MMCD = $176) remained similar pre- vs post-transition (all p > .05). Conclusions: Transitioning to PP3M was associated with an improvement in adherence and in comorbidity-related outcomes related to substance-related and addictive disorders, psychoses, diabetes without chronic complication, and drug abuse. These findings suggest PP3M may enhance comorbidity-related outcomes and adherence while remaining cost neutral.

Multiple real-world studies have reported potential cost savings associated with second-generation antipsychotic long-acting injectable therapies (SGA-LAIs), including once monthly paliperidone palmitate (PP1M). Yet, only about 12% of Medicaid patients with schizophrenia initiate SGA-LAIs, with poor adherence contributing to frequent relapse among patients on oral atypical antipsychotics (OAAs). The objective of this study was to project the economic impact when an incremental proportion of non-adherent patients with a recent relapse switched from OAAs to PP1M.A 12 month decision-tree model was developed from a Medicaid payers' perspective. The target population was non-adherent OAA patients with a recent relapse. At equal adherence, risk of relapse was equal between PP1M and OAAs, and OAA patients remained non-adherent until treatment switch. Outcomes included number of relapses, relapse costs and pharmacy costs.Based on a hypothetical health plan of 1 million members, 3037 schizophrenia patients were non-adherent on OAAs with a recent relapse. Compared to continuing OAAs, switching 5% of patients (n = 152) to PP1M resulted in net schizophrenia-related cost savings of $674,975 at a plan level, $4445 per patient switched per year and $0.0562 per member per month, with a total of 92 avoided relapses over 12 months. Total annual plan level schizophrenia-related costs were $114.1 M when all patients switched to PP1M before any subsequent relapse (n = 3037), $123.4 M when patients switched to PP1M after a first subsequent relapse (n = 2631), and $127.6 M when all patients continued OAAs. Switching all patients to PP1M before any subsequent relapse averted 917 relapses, at a lower cost per patient switched ($37,559) compared to switching after a first subsequent relapse ($45,089) or continuing OAAs ($42,005).Over 12 months, pharmacy costs associated with switching patients from OAAs to PP1M were offset by reduced relapse rates and schizophrenia-related healthcare expenditures, with earlier use of PP1M projected to generate greater cost savings.

The aim of this article was to describe and compare treatment patterns, health care resource utilization (HRU), and health care costs before and after transition in veterans with schizophrenia who were transitioned from paliperidone palmitate given once monthly (PP1M) to paliperidone palmitate given every 3 months (PP3M) according to prescribing-information guidelines.This retrospective, longitudinal study was conducted using electronic health records data from the Veterans Health Administration (VHA). Veterans were eligible for inclusion if they were aged 18years or older, had ≥1 dispensation of PP3M, were enrolled with VHA benefits for ≥24 months prior to transition to PP3M, had ≥1 schizophrenia diagnosis, were transitioned to PP3M according to prescribing-information guidelines (operationalized as no gap in PP1M treatment of45days during the 4 months prior to PP3M transition, with the same dosage in the last 2 PP1M dispensations), and had appropriate dose conversion. Treatment patterns, HRU, and costs 6 months pre and post PP3M transition were described and compared using the McNemar test and the Wilcoxon signed rank test.Of the 277 veterans identified, the majority were men (92.8%); the median age was 56.5years. Among 197 veterans who had at least 6 months of follow-up pre and post PP3M transition, oral antipsychotic use was significantly decreased (from 49.7% to 43.1%; P = 0.0326). Additionally, the mean number of days spent in an inpatient setting (41.4vs 21.6; P = 0.0164), the mean number of outpatient visits per patient (31.0vs 25.6; P0.0001), and the mean total health care costs ($27,745vs $23,772; P = 0.0050) were significantly decreased.After transitioning to PP3M treatment, veterans had significantly reduced use of oral antipsychotics, HRU, and costs. Although generalizability may be limited due to the veteran population and to those who transitioned according to PP3M prescribing guidelines, future studies in other patient populations may be used to extend these conclusions.

Hepatitis C virus (HCV) infection is widespread and associated with high economic costs and reduced quality of life, but the impact of untreated HCV infection on patient outcome is not well understood. To estimate the impact of untreated HCV infection on work productivity, daily activity, healthcare use, economic costs, and health-related quality of life (HRQoL). Respondents to the 2010 US National Health and Wellness Survey (n = 75,000) reporting physician diagnosis of HCV infection but not current or previous treatment (patients) were matched to respondents without HCV infection (controls) by use of propensity scores. Those reporting infection with hepatitis B virus (HBV) or human immunodeficiency virus (HIV) were excluded. Self-reported work impairment, activity impairment, healthcare resource use, and HRQoL were compared between patients and controls. Indirect and direct costs were estimated. A total of 306 patients met inclusion criteria. Patients were more impaired at work than controls, with overall work impairment of 26 % versus 15 %, respectively (P

Background Rotavirus is the leading cause of severe diarrhea in children worldwide. We systematically reviewed the burden of rotavirus gastroenteritis (RVGE) and distribution of rotavirus strains in Asia. Methods We searched MEDLINE, EMBASE and the World Health Organization (WHO) website for the term “rotavirus” and the name of each country. We included studies that were conducted in children between 2000 and 2011 and that examined the epidemiology, health and/or economic burden of RVGE, and G and P-type distribution in Eastern, South East, Southern and Central Asia. Random effects models were used to pool the proportions of RVGE. We also estimated child mortality due to RVGE using the updated WHO and United Nations Children's Fund's mortality estimates in 2008. Results The search identified 113 eligible articles. The incidence rates of rotavirus-related hospitalizations in children under 5 years of age ranged from 2.1 to 20.0 cases per 1000 children per year with the highest rates reported in Bangladesh, South Korea, Taiwan, Thailand, and Vietnam. Rotavirus accounted for 37.5% of year-round hospitalized gastroenteritis cases, with higher proportions reported in South East Asia. Rotavirus was associated with approximately 145,000 deaths every year in Asia, with the greatest numbers occurring in India, Pakistan, and Indonesia. The highest annual societal costs of treating RVGE were reported in China (US$365 million), followed by Japan (US$254 million) and India (US$41–72 million). A diversity of rotavirus G and P-types was observed across Asia and the distribution of strains differed by country and year. The most common strains were G1P[8] (23.6%), G2P[4] (11.8%), G3P[8] (18.9%), and G9P[8] (7.4%). Conclusions Rotavirus is associated with substantial hospitalizations and deaths among children and causes large healthcare expenditures throughout Asia. Safe and effective rotavirus vaccines could substantially reduce the burden of disease.

Objectives. We sought to compare the burden of hospitalizations associated with rotavirus gastroenteritis (RGE) in children younger than 5 years in US Medicaid and non-Medicaid populations in 2000 and 2003. Methods. We used the Kids' Inpatient Database (KID) to examine the burden of RGE-associated hospitalizations in terms of numbers and rates of hospitalizations, lengths of stay, and hospital charges. Two indirect methods were also used to estimate RGE-associated hospitalizations, because rotavirus testing is not routinely performed. Results. Approximately 40% of children younger than 5 years were enrolled in Medicaid in 2003, but this population accounted for nearly 50% of all RGE-associated hospitalizations and 60% of total charges. Children enrolled in Medicaid had significantly greater hospitalization rates, average lengths of stay, and average charges per stay than did those not enrolled. Conclusions. Although RGE affects all socioeconomic groups, the Medicaid population accounted for a disproportionate number of the hospitalizations. With the inclusion of rotavirus vaccines in the pediatric immunization schedule, it is important that US children, especially those enrolled in Medicaid programs, are vaccinated to reduce the burden of RGE.

The recent approval of two protease inhibitors, boceprevir and telaprevir, is likely to change the management of chronic hepatitis C virus (HCV) genotype 1 infection. We evaluated the long-term clinical outcomes and the cost effectiveness of therapeutic strategies using boceprevir with peginterferon plus ribavirin (PR) in comparison with PR alone for treating HCV genotype 1 infection in Portugal. A Markov model was developed to project the expected lifetime costs and quality-adjusted life-years (QALYs) associated with PR alone and the treatment strategies outlined by the European Medicines Agency in the boceprevir summary of product characteristics. The boceprevir-based therapeutic strategies differ according to whether or not the patient was previously treated and whether or not the patient had compensated cirrhosis. The model simulated the experience of a series of cohorts of chronically HCV-infected patients (each defined by age, sex, race and fibrosis score). All treatment-related inputs were obtained from boceprevir clinical trials – SPRINT-2, RESPOND-2 and PROVIDE. Estimates of the natural history parameters and health state utilities were based on published studies. Portugal-specific annual direct costs of HCV health states were estimated by convening a panel of experts to derive health state resource use and multiplying the results by national unit costs. The model was developed from a healthcare system perspective with a timeframe corresponding to the remaining duration of the patients’ lifetimes. Both future costs and QALYs were discounted at 5 %. To test the robustness of the conclusions, we conducted deterministic and probabilistic sensitivity analyses. In comparison with the treatment with PR alone, boceprevir-based regimens were projected to reduce the lifetime incidence of advanced liver disease, liver transplantation, and liver-related death by 45–51 % and increase life expectancy by 2.3–4.3 years. Although the addition of BOC increased treatment costs by €13,300–€19,700, the reduction of disease burden resulted in a decrease of €5,400–€9,000 in discounted health state costs and an increase of 0.68–1.23 in discounted QALYs per patient. The incremental cost-effectiveness ratios of the boceprevir-based regimens compared with PR among previously untreated and previously treated patients were €11,600/QALY and €8,700/QALY, respectively. The results were most sensitive to variations in sustained virologic response rates, discount rates and age at treatment. Adding boceprevir to PR was projected to reduce the number of liver complications and liver-related deaths, and to be cost effective in treating both previously untreated and treated patients.

Objectives The phase 3 trial, Serine Protease Inhibitor Boceprevir and PegIntron/Rebetol-2 (RESPOND-2), demonstrated that the addition of boceprevir (BOC) to peginterferon-ribavirin (PR) resulted in significantly higher rates of sustained virologic response (SVR) in previously treated patients with chronic hepatitis C virus (HCV) genotype-1 infection as compared with PR alone. We evaluated the cost-effectiveness of treatment with BOC in previously treated patients with chronic hepatitis C in the United States using treatment-related data from RESPOND-2 and PROVIDE studies. Methods We developed a Markov cohort model to project the burden of HCV disease, lifetime costs, and quality-adjusted life-years associated with PR and two BOC-based therapies—response-guided therapy (BOC/RGT) and fixed-duration therapy for 48 weeks (BOC/PR48). We estimated treatment-related inputs (efficacy, adverse events, and discontinuations) from clinical trials and obtained disease progression rates, costs, and quality-of-life data from published studies. We estimated the incremental cost-effectiveness ratio (ICER) for BOC-based regimens as studied in RESPOND-2, as well as by patient's prior response to treatment and the IL-28B genotype. Results BOC-based regimens were projected to reduce the lifetime incidence of liver-related complications by 43% to 53% in comparison with treatment with PR. The ICER of BOC/RGT in comparison with that of PR was $30,200, and the ICER of BOC/PR48 in comparison with that of BOC/RGT was $91,500. At a willingness-to-pay threshold of $50,000, the probabilities of BOC/RGT and BOC/PR48 being the preferred option were 0.74 and 0.25, respectively. Conclusions In patients previously treated for chronic HCV genotype-1 infection, BOC was projected to increase quality-adjusted life-years and reduce the lifetime incidence of liver complications. In addition, BOC-based therapies were projected to be cost-effective in comparison with PR alone at commonly used willingness-to-pay thresholds.

To quantify the health-related quality of life (HRQoL) burden of hepatitis C virus (HCV) infection among a broad sample of adults in Brazil, particularly among those 40 years of age and older.This was a retrospective observational study of data from the 2011 Brazil National Health and Wellness Survey, a large (n = 12 000) cross-sectional survey that includes information on medical conditions and health outcomes, including the Medical Outcomes Study Short-form 12 health questionnaire, version 2 (SF-12v2). Respondents who reported a physician diagnosis of HCV infection were compared with those who reported never experiencing HCV on the Mental (MCS) and Physical (PCS) Component Summary scores and SF-6D health utility scores. Unadjusted comparisons were conducted with chi-square tests for categorical variables and t-tests for continuous variables. Regression was used to adjust outcomes for potential confounds. Subgroup analyses were conducted on those 40 years of age and older.Unadjusted comparisons between respondents infected with HCV (n = 100) and controls (n = 11 694) revealed similar MCS and PCS scores, but HCV patients had lower SF-6D utility scores (0.70 vs. 0.73, P0.05). Regressions adjusting for demographic and health characteristics provided similar results to unadjusted comparisons. Subgroup analyses of respondents 40 years of age and older revealed decrements in both MCS (45.95 vs. 49.72, P0.05) and SF-6D (0.71 vs. 0.76, P0.05). PCS scores were comparable in HCV patients and controls.HCV infection in Brazil causes significant HRQoL burden, especially among the older population. Prevention measures to curtail the spread of the virus in Brazil should provide societal benefits in terms of quality of life, in addition to preventing morbidity and mortality from chronic infection.

To assess the effect of persistence of use of warfarin sodium, aspirin, or clopidogrel bisulfate on stroke recurrence in a Medicaid high-risk, largely female, African American population.Prospective non-concurrent cohort, longitudinal data analysis of medical and pharmacy claims of stroke patients from Medicaid managed care organizations between January 1, 2001, and December 31, 2003.Cox proportional hazards models were used to predict the likelihood of avoiding a recurrence as a function of persistence of use of the initial medication (warfarin, aspirin, or clopidogrel) after stroke, adjusting for age, race, sex, hypertension and other comorbidities, and the pharmacotherapies prescribed. We used propensity scores to adjust for confounding by indication.Among 925 stroke patients (64.6% female, 75.1%or =50 years, and 57.8% African American), hypertension and heart disease were the most prevalent comorbidities (66.1% and 65.1%, respectively); most initial strokes were nonhemorrhagic. Persistence of use of warfarin, aspirin, or clopidogrel after stroke increased the likelihood of avoiding a recurrence (hazard ratio [HR], 1.57; 95% confidence interval [CI], 1.22-2.01). Having a hemorrhagic stroke initially (HR, 0.37; 95% CI, 0.18-0.74) or having heart disease (HR, 0.82; 95% CI, 0.67-1.01), hypertension (HR, 0.63; 95% CI, 0.51-0.79), or diabetes mellitus (HR, 0.74; 95% CI, 0.60-0.91) after an initial stroke significantly decreased the likelihood of avoiding a recurrence. Patient's age, race, sex, and urban residence did not significantly predict the likelihood of avoiding a recurrence.Persistence of use of the initial stroke preventive medication after stroke is effective in avoiding a recurrence. Hemorrhagic stroke, heart disease, hypertension, and diabetes increase the likelihood of a recurrence.

Background Few studies have examined the impact of Hepatitis C virus (HCV) infection on patient reported outcomes in Europe. This study was conducted to assess the burden of HCV infection in terms of work productivity loss, activity impairment, health-related quality of life, healthcare resource utilization, and associated costs. Methods The 2010 European National Health and Wellness Survey (n = 57,805) provided data. Patients reporting HCV infection in France, Germany, the UK, Italy, and Spain were matched to respondents without HCV using propensity scores. Outcome measures included the Work Productivity and Activity Impairment (WPAI) questionnaire and the Medical Outcomes Study Short Form-12 (SF-12v2) questionnaire. Subgroup analyses focused on treatment-naïve patients. Results HCV Patients (n = 286) had more work impairment (30% vs. 18%, p p p p p n = 139) also reported higher work impairment (29% vs. 15%, p p p p Conclusion HCV infection in Europe is associated with considerable economic and humanistic burden. This is also true of diagnosed patients who have never been treated for HCV.

Background A fever is an increase in the body's temperature above normal. This study examined how US pediatricians perceive and manage fever generally versus fever occurring after vaccination in infants up to six months of age. Methods A web-based survey of 400 US pediatricians subscribing to the Physician Desk Reference was conducted in December 2008. Data were collected on the respondents' socio-demographics, number of years in practice, type of practice, their definition of fever severity in infants, and their recommendations for managing fever. Generalized Estimating Equations were used to estimate the odds of a pediatrician recommending an emergency room visit (ER) or a hospital admission, office visits, or other treatment option, as a function of infant's age, temperature, whether the infant has recently received a vaccine, and whether the fever was reported during or after office hours, adjusting for practice type and socio-demographic variables. Results On average, the 400 responding pediatricians' (64% were female, average age of 49 years, years in practice = 20 years) threshold for extremely serious fever was ≥39.5°C and ≥ 40.0°C for infants 0-2 month and >2-6 month of age respectively. Infants were more likely to be referred to an ER or hospital admission if they were ≤ 2 months of age (Odds Ratio [OR], 29.13; 95% Confidence interval [95% CI], 23.69-35.82) or >2-4 months old (OR 3.37; 95% CI 2.99-3.81) versus > 4 to 6 months old or if they had a temperature ≥ 40.0°C (OR 21.06; 95% CI 17.20-25.79) versus a temperature of 38.0-38.5°C. Fever after vaccination (OR 0.29; 95% CI 0.25-0.33) or reported during office hours (OR 0.17; 95% CI 0.15-0.20) were less likely to result in referral to ER or hospital admission. Conclusion Within this sample of US pediatricians, perception of the severity of fever in infants, as well as the response to infant fever are likely to depend on the infant's age. Recommendations for the management of fever in infants are likely to depend on fever severity level, the infant age, timing in relation to recent vaccination, and the time of day fever is reported. Our results indicate that US pediatricians are more concerned about general fever than fever following vaccination.

Background Rotavirus gastroenteritis (RVGE) is the most common cause of severe childhood diarrhea worldwide. Objectives were to estimate the burden of RVGE among children less than five years old in the Middle East (Bahrain, Iran, Iraq, Israel, Jordan, Kuwait, Oman, Qatar, Saudi Arabia, Syria, UAE, Yemen), North Africa (Algeria, Egypt, Libya, Morocco, Tunisia) and Turkey. Methods A comprehensive literature search was conducted in major databases on the epidemiology and burden of rotavirus among children less than five years old between 1999 and 2009. Data from each country was extracted and compared. Results The search identified 43 studies. RVGE was identified in 16-61% of all cases of acute gastroenteritis, with a peak in the winter. RVGE-related hospitalization rates ranged from 14% to 45%, compared to 14%-28% for non-RVGE. Annually, RVGE caused up to 112 fatalities per 100,000 in certain countries in the region. Hospitalization costs ranged from $1.8 to $4.6 million annually, depending on the country. The most recent literature available showed that G1P[8] was the most prevalent genotype combination in 8 countries (range 23%-56%). G2P[4] was most prevalent in 4 countries (26%-48%). G9P[8] and G4P[8] were also frequently detected. Conclusions RVGE is a common disease associated with significant morbidity, mortality, and economic burden. Given the variety and diverse rotavirus types in the region, use of a vaccine with broad and consistent serotype coverage would be important to help decrease the burden of RVGE in the Middle East and North Africa.

International audience; BACKGROUND: SPRINT-2 demonstrated that boceprevir (BOC), an oral hepatitis C virus (HCV)- nonstructural 3 (NS3) protease inhibitor, added to peginterferon alfa-2b (P) and ribavirin (R) significantly increased sustained virologic response rates over PR alone in previously untreated adult patients with chronic HCV genotype 1. We estimated the long-term impact of triple therapy vs. dual therapy on the clinical burden of HCV and performed a cost-effectiveness evaluation. METHODS: A Markov model was used to estimate the incidence of liver complications, discounted costs (2010 US$), quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios (ICERs) of three treatment strategies for treatment-naive patients with chronic HCV genotype 1. The model simulates the treatment regimens studied in SPRINT-2 in which PR was administered for 4 weeks followed by: 1) placebo plus PR for 44 weeks (PR48); 2) BOC plus PR using response guided therapy (BOC/RGT); and 3) BOC plus PR for 44 weeks (BOC/PR48) and makes projections within and beyond the trial. HCV-related state-transition probabilities, costs, and utilities were obtained from previously published studies. All costs and QALYs were discounted at 3%. RESULTS: The model projected approximately 38% and 43% relative reductions in the lifetime incidence of liver complications in the BOC/RGT and BOC/PR48 regimens compared with PR48; respectively. Treatment with BOC/RGT is associated with an incremental cost of $10,348 and an increase of 0.62 QALYs compared to treatment with PR48. Treatment with BOC/PR48 is associated with an incremental cost of $35,727 and an increase of 0.65 QALYs compared to treatment with PR48. The ICERs were $16,792/QALY and $55,162/QALY for the boceprevir-based treatment groups compared with PR48, respectively. The ICER for BOC/PR48 compared with BOC/RGT was $807,804. CONCLUSION: The boceprevir-based regimens used in the SPRINT-2 trial were projected to substantially reduce the lifetime incidence of liver complications and increase the QALYs in treatment-naive patients with hepatitis C genotype 1. It was also demonstrated that boceprevir-based regimens offer patients the possibility of experiencing great clinical benefit with a shorter duration of therapy. Both boceprevir-based treatment strategies were projected to be cost-effective at a reasonable threshold in the US when compared to treatment with PR48.
