Objective: The objective of this study was to characterize racial-ethnic variation in diagnoses and treatment of mental disorders in large not-for-profit health care systems.

Methods: Participating systems were 11 private, not-for-profit health care organizations constituting the Mental Health Research Network, with a combined 7,523,956 patients age 18 or older who received care during 2011. Rates of diagnoses, prescription of psychotropic medications, and total formal psychotherapy sessions received were obtained from insurance claims and electronic medical record databases across all health care settings.

Objective: In 2012, the Centers for Medicare and Medicaid Services implemented a policy that penalizes hospitals for "excessive" all-cause hospital readmissions within 30 days after discharge from an index hospitalization for heart failure (HF), acute myocardial infarction (AMI), and pneumonia. The aim of this study was to investigate the influence of psychiatric comorbidities on 30-day all-cause readmissions following hospitalizations for HF, AMI, and pneumonia.

Methods: Data from 2009-2011 were derived from the HMO Research Network Virtual Data Warehouse of 11 health systems affiliated with the Mental Health Research Network.

Purpose: Little is known about opioid use after bariatric surgery among patients who did not use opioids chronically before surgery. Our purpose was to determine opioid use the year after bariatric surgery among patients who did not use opioids chronically pre-surgery and to identify pre-surgery characteristics associated with chronic opioid use after surgery.

Methods: This retrospective cohort study across nine US health systems included 10 643 patients aged 21 years or older who underwent bariatric surgery and who were not chronic opioid users pre-surgery.

Article Synopsis
  • The study investigates the opioid use in obese patients who were chronic opioid users before undergoing bariatric surgery and whether their usage changes post-surgery.
  • It involves a retrospective analysis of 11,719 patients from varied U.S. health systems, assessing opioid consumption one year before and after the procedure, excluding the first 30 days post-surgery.
  • Results show that a significant majority (77%) of chronic opioid users continued their usage after surgery, with a slight increase in average daily morphine equivalents, and the degree of body mass index reduction did not significantly impact changes in opioid use.

Objective: Bariatric surgery is the most effective therapy for severe obesity. People with bipolar disorder have increased risk of obesity, yet are sometimes considered ineligible for bariatric surgery due to their bipolar disorder diagnosis. This study aimed to determine if bariatric surgery alters psychiatric course among stable patients with bipolar disorder.

A priority research and clinical agenda is to identify determinants of cognitive impairment in individuals with neuropsychiatric disorders (NPD). The bidirectional association between NPD and cognitive performance has been reported to be mediated and/or moderated by obesity in a subset of individuals. Obesity can be conceptualized as a neurotoxic phenotype among individuals with NPD as evidenced by alterations in the structure and function of neural circuits and disseminated networks, diminished cognitive performance, and adverse effects on illness trajectory.

To examine ethnic differences in hemoglobin testing practices and to test the hypothesis that ethnicity is an independent predictor of anemia among patients with diabetes mellitus. We conducted a panel study to assess the rate of hemoglobin testing during 1999-2001 and the period prevalence and incidence of anemia among 79,985 adults with diabetes mellitus receiving care within Kaiser Permanente of Northern California. Anemia was defined as hemoglobin <13.

Background: Use of four or more prescription medications is considered a risk factor for falls in older people. It is unclear whether this polypharmacy-fall relationship differs for adults with diabetes.

Objective: We evaluated the association between number of prescription medications and incident falls in a multi-ethnic population of type-2 diabetes patients in order to establish an evidence-based medication threshold for fall risk in diabetes.

Background: Diabetes disproportionately affects Latinos. However, examining Latinos as one group obscures important intra-group differences. This study examined how generational status, duration of US residence, and language preference are associated with diabetes prevalence and to what extent these explain the higher prevalence among Latinos.

Objective: Describe a novel approach to comprehensively summarize medication adherence.

Data Sources/study Setting: Kaiser Permanente Northern California Diabetes Registry (n approximately 220,000)

Study Design: In a new prescription cohort design (27,329 subjects prescribed new medications), we used pharmacy utilization data to estimate adherence during 24 months follow-up. Proportion of time without sufficient medications (medication gaps) was estimated using a novel measure (New Prescription Medication Gaps [NPMG]) and compared with a traditional measure of adherence.
