Accuracy of Electronic Medical Record Follow-Up Data for Estimating the Survival Time of Patients With Cancer.

Purpose: For real-world evidence, it is convenient to use routinely collected data from the electronic medical record (EMR) to measure survival outcomes. However, patients can become lost to follow-up, causing incomplete data and biased survival time estimates. We quantified this issue for patients with metastatic cancer seen in an academic health system by comparing survival estimates from EMR data only and from EMR data combined with high-quality cancer registry data.

Natural Language Processing to Identify Cancer Treatments With Electronic Medical Records.

Purpose: Knowing the treatments administered to patients with cancer is important for treatment planning and correlating treatment patterns with outcomes for personalized medicine study. However, existing methods to identify treatments are often lacking. We develop a natural language processing approach with structured electronic medical records and unstructured clinical notes to identify the initial treatment administered to patients with cancer.

Automated model versus treating physician for predicting survival time of patients with metastatic cancer.

Objective: Being able to predict a patient's life expectancy can help doctors and patients prioritize treatments and supportive care. For predicting life expectancy, physicians have been shown to outperform traditional models that use only a few predictor variables. It is possible that a machine learning model that uses many predictor variables and diverse data sources from the electronic medical record can improve on physicians' performance.

A comparative analysis of current blood pressure management guidelines in people with and without diabetes.

Hypertension is the leading global risk factor for cardiovascular disease and premature death. Recommendations from current guidelines of blood pressure (BP) management differ in many ways; therefore, we did an overview and comparative analysis of major clinical guidelines of BP management in people with and without diabetes, including the definition and classification of hypertension, initiation of antihypertensive drug therapy, BP control targets, and antihypertensive treatment strategies. BP management in patients with diabetes was discussed in great detail using both hypertension and diabetes guidelines.

Automated Survival Prediction in Metastatic Cancer Patients Using High-Dimensional Electronic Medical Record Data.

Background: Oncologists use patients' life expectancy to guide decisions and may benefit from a tool that accurately predicts prognosis. Existing prognostic models generally use only a few predictor variables. We used an electronic medical record dataset to train a prognostic model for patients with metastatic cancer.

Increased Risk of Cutaneous Squamous Cell Carcinoma After Vismodegib Therapy for Basal Cell Carcinoma.

Importance: Smoothened inhibitors (SIs) are a new type of targeted therapy for advanced basal cell carcinoma (BCC), and their long-term effects, such as increased risk of subsequent malignancy, are still being explored.

Objective: To evaluate the risk of developing a non-BCC malignancy after SI exposure in patients with BCC.

Design, Setting, And Participants: A case-control study at Stanford Medical Center, an academic hospital.

Does a single-pill antihypertensive/lipid-lowering regimen improve adherence in US managed care enrolees? A non-randomized, observational, retrospective study.

Background: A previous study in 4703 patients suggested that a single-pill combination of amlodipine and atorvastatin is associated with greater adherence to therapy than a two-pill calcium channel antagonist (calcium channel blocker [CCB]) and HMG-CoA reductase inhibitor (statin) regimen. However, the impact of prior medication use on the potential adherence benefits of single-pill amlodipine/atorvastatin has not been studied.

Objective: To compare adherence to single-pill amlodipine/atorvastatin versus two-pill CCB + statin regimens in a large managed care population, stratified according to prior CCB and statin use.

Randomized, double-blind, multicenter, placebo-controlled study evaluating the effect of aldosterone antagonism with eplerenone on ventricular remodeling in patients with mild-to-moderate heart failure and left ventricular systolic dysfunction.

Background: Aldosterone antagonism has been studied in patients with advanced heart failure (HF) and also in patients with post-myocardial infarction and left ventricular (LV) dysfunction with HF symptoms. Few data are available on effects of aldosterone antagonism in patients with mild-to-moderate HF.

Methods And Results: In a multicenter, randomized, double-blind, placebo-controlled study in patients with mild-to-moderate HF and LV systolic dysfunction, patients with New York Heart Association class II/III HF and LV ejection fraction (EF) < or =35% were randomly assigned to receive eplerenone 50 mg/d versus placebo in addition to contemporary background therapy.

Combined association of lipids and blood pressure in relation to incident cardiovascular disease in the elderly: the cardiovascular health study.

Background: Hypertension and dyslipidemia are highly prevalent in the elderly. We studied the combined impact of both conditions on cardiovascular disease (CVD) events.

Methods: We studied 4,311 participants aged 65-98 (61.

Estimates of commercial population at high risk for cardiovascular events: impact of aggressive cholesterol reduction.

Objectives: To model the financial and health outcomes impact of intensive statin therapy compared with usual care in a high-risk working-age population (actively employed, commercially insured health plan members and their adult dependents). The target population consists of working-age people who are considered high-risk for cardiovascular disease events because of a history of coronary heart disease.

Study Design: Three-year event forecast for a sample population generated from the National Health and Nutrition Examination Survey data.
