AIM: The goal of this study was to compare postacute care costs of three care management interventions. MATERIALS & METHODS: A total of 202 hospitalized older adults with cognitive impairment received either Augmented Standard Care, Resource Nurse Care or the Transitional Care Model. The Lin method was used to estimate costs at 30 and 180 days postindex hospital discharge. RESULTS: The Transitional Care Model had significantly lower costs than the Augmented Standard Care group at both 30 (p < 0...

AIM: Efficacy of colistin and ampicillin-sulbactam have not been compared in treatment of ventilator-associated pneumonia due to A. baumannii. Efficacy of colistin and ampicillin-sulbactam in combination with meropenem were compared in treatment of ventilator-associated pneumonia due to carbapenem-resistant A. baumannii. METHOD: 47 patients with ventilator-associated pneumonia due to carbapenem-resistant A. baumannii were randomized to receive meropenem/colistin or meropenem/ampicillin-sulbactam for 14 days...

Although published noninferiority trials (NITs) generally conclude that the experimental intervention being studied is noninferior compared with standard therapy or active control, NIT quality is often not satisfactory. We have proposed 14 questions to assist in evaluating the clinical evidence of the experimental versus standard therapy. The aim of these questions is to critically appraise NITs and support proper interpretation of study results. Readers should not only consider whether the confidence interval of the primary effect measure falls within the prespecified noninferiority margin (thus concluding noninferiority), but also assess the similarities between primary and secondary outcomes for the experimental and standard therapy...

AIM: The current study aims to propose and internally validate 'M-bioscore', which is a model to help predict the outcomes of untreated metastatic breast cancer patients. METHODOLOGY: Surveillance, epidemiology and end results (SEER) database (2010-2013) was accessed. Patients were divided into two groups: a training set and a validation set. Through a Cox proportional model, multivariate analysis for potential prognostic factors was performed. M-bioscore was calculated for all patients...

MATERIALS & METHODS: Two retrospective cohort studies were independently conducted using the PharMetrics and MarketScan databases. Included patients were aged ≥18 years, and had ≥1 MM diagnosis and ≥1 claim for systemic therapy from 2004 to 2015. RESULTS: A total of 1654 and 1329 patients were identified in PharMetrics and MarketScan, respectively...

AIM: A matching-adjusted indirect comparison (MAIC) of sunitinib and everolimus has been previously reported based on the RADIANT-3 everolimus trial. We performed an analysis using updated overall survival (OS) data based on sunitinib's trial (A6181111). METHODS: The MAIC matched on all baseline characteristics available from both studies. An anchored MAIC was performed for progression-free survival (PFS); an unanchored analysis was deemed more appropriate for OS due to crossover in both trials...

AIM: We examined characteristics of early sacubitril/valsartan users in a large US electronic health records database. PATIENTS & METHODS: We identified three cohorts of patients with heart failure (HF): sacubitril/valsartan patients with a prior HF diagnosis; patients with HF with reduced ejection fraction; and patients with HF treated with an angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker and a β-blocker. RESULTS: Sacubitril/valsartan patients were younger than patients in the other cohorts; the mean age of sacubitril/valsartan patients increased by 2 years in the first 15 months of marketing...

PATIENTS & METHODS: Pilot retrospective study analyzing data extracted from medical charts of patients ≥6 years of age prescribed Trokendi XR. RESULTS: Trokendi XR was the most commonly used to prevent migraine...

AIM: The aim of this study was to assess the effectiveness of the follow-up (FU) of patients after head and neck cancer treatment. MATERIALS & METHODS: This is a retrospective cross-sectional study and concerns the analysis of outpatient records of 85 women and 355 men who reported at FU visits between 2011 and 2016 in ENT Department in the University Of Medical Sciences in Poznan, Poland. RESULTS: The value of the FU scheme was confirmed by a high rate of recurrence detected in a medical examination (60%) and routine imaging studies (27%), as opposed to only 13% in spontaneous reports...

AIM: Due to the difference in epidemiology and outcomes between eastern and western populations with Type 2 diabetes mellitus (T2DM), an important challenge is determining how useful the outcomes from diabetes models based on western populations are for eastern patients. Consequently, the principal aim of this study was to develop and validate a Health Policy Model (Chinese Outcomes Model for T2DM [COMT]) for supporting Chinese medical and health economic studies. METHODS: The model is created to simulate a series of important complications of T2DM diabetes based on the latest Risk Equations for Complications of Type 2 Diabetes, which was adjusted by adding the adjustment regulator to the linear predictor within the risk equation...

AIM: To calculate conditional power in comparative two-period studies with previously observed baseline data. METHOD: Isolate the variability attributable to the yet-to-observed data and modify the standard power formulae. RESULTS: For illustration, we examine rates of opioid overdose before and after a reformulation of one opioid product. The null hypothesis posited no impact of the reformulation, alternative hypotheses posited possible impacts, and ancillary hypotheses posited different secular pre-post changes directly observable in comparators...

AIM: To assess robustness of findings in recent systematic reviews of atypical antipsychotics in schizophrenia patients in the presence of heterogeneity. METHODS: Relative efficacy was measured in seven direct comparisons of mean difference (MD) in average positive and negative syndrome scale total score and comparisons between conventional meta-analysis results and four alternate meta-analytic strategies using the difference in MD (ΔMD). RESULTS: MDs in positive and negative syndrome scale total score were smaller in the conventional meta-analyses than those for three of the four analytic strategies...

AIM: To evaluate the comparative effectiveness of biologics in inhibiting radiographic progression among rheumatoid arthritis (RA) patients. MATERIALS & METHODS: Bayesian network meta-analysis of published trials investigating the USA FDA approved biologics treatment in RA patients, using methotrexate (MTX) as the reference comparator. RESULTS: Nine trials met the inclusion criteria for base case analysis. Compared with MTX, most biologics (except golimumab) + MTX had significantly lower rates of radiographic progression at 1 year...

AIM: To compare risk of hospitalization in patients with bipolar I disorder (BD-I) initiating long-acting injectable antipsychotics (LAIs). MATERIALS & METHODS: Using Truven Health Analytics MarketScan® (Medicaid, Commercial and Medicare Supplemental) databases (2012-2016), patients (≥18 years) with BD-I with a LAI (aripiprazole once monthly [AOM 400], fluphenazine-LAI, haloperidol-LAI, risperidone-LAI and paliperidone-4-week-LAI) were identified. RESULTS: The adjusted odds of having hospitalization were significantly higher in haloperidol-LAI (Odds ratio [95% CI]: 1...

AIM: To assess patient experience with chemotherapy and avelumab in metastatic Merkel cell carcinoma (mMCC). METHODS: In the JAVELIN Merkel 200 trial, chemotherapy-refractory mMCC patients could participate in optional qualitative interviews at baseline documenting recollection of previous chemotherapy experience, and at weeks 13/25 documenting current experience with avelumab. Functional Assessment of Cancer Therapy subscale for melanoma questionnaire (FACT-M) was administered in parallel...

AIM: To compare the overall survival of anaplastic lymphoma kinase-positive non-small-cell lung cancer patients who received alectinib with those who received ceritinib. MATERIALS & METHODS: Two treatment arms (alectinib [n = 183] and ceritinib [n = 67]) were extracted from clinical trials and an electronic health record database, respectively. Propensity scores were applied to balance baseline characteristics. Kaplan-Meier and multivariate Cox regression were conducted...
