Background: Intraoperative hypotension (IOH) is well-described in the academic setting but not in community practice. IOH is associated with risk of postoperative morbidity and mortality. This is the first report of IOH in the community setting using the IOH measure definition from the Centers for Medicare and Medicaid Services Merit-based Incentive Payment System program.

Introduction: Reliable and valid measures are needed to assess the patient-centeredness of clinical care among Latino populations.

Methods: We translated the Consultation and Relational Empathy (CARE) measure from English to Spanish and assessed its psychometric properties using data from 349 Latino parents/guardians visiting a pediatric clinic. Using confirmatory factor analysis, we examined the psychometric properties of the Spanish CARE measure.

Background: Intraoperative hypotension is common and associated with organ injury and death, although randomized data showing a causal relationship remain sparse. A risk-adjusted measure of intraoperative hypotension may therefore contribute to quality improvement efforts.

Methods: The measure we developed defines hypotension as a mean arterial pressure <65 mm Hg sustained for at least 15 cumulative minutes.

Introduction: This study evaluates the impact of practice participation in a pediatric patient-centered medical home learning collaborative on preventable emergency department (ED) visits among children in MassHealth (Massachusetts Medicaid/Children's Health Insurance Program).

Methods: Claims and enrollment data were extracted for child MassHealth members (aged 3-18) comprising 2 groups: members enrolled in a group of 13 child-serving practices that participated in an intensive, 29-month long patient-centered medical home learning collaborative (intervention group), and members enrolled in a group of 12 comparison practices with roughly similar panel size, type, and geographic location (comparison group). Preventable ED visits were identified using a modified version of the New York University ED algorithm.

Objective: To pilot test the effectiveness, feasibility, and acceptability of instituting a 15-pill quantity default in the electronic health record for new Schedule II opioid prescriptions.

Design: A mixed-methods pilot study in two health systems, including pre-post analysis of prescribed opioid quantity and focus groups or interviews with prescribers and health system administrators.

Methods: We implemented a 15-pill electronic health record default for new Schedule II opioids and assessed opioid quantity before and after implementation using electronic health record data on 6,390 opioid prescriptions from 448 prescribers.

As primary care models increasingly include nonphysician team members, more attention should be paid to patient- and family-centered care (PFCC) among medical assistants (MAs). The aims of this article are to describe parent perceptions of PFCC by MAs and assess associations between MA PFCC and other perceptions of their care experience. To assess PFCC, we administered the CARE (Consultation and Relational Empathy) measure to the parent/guardian of 360 children following a primary care visit.

Objectives The objective of this study was to describe factors that influence the ability of state Medicaid agencies to report the Centers for Medicare & Medicaid Services' (CMS) core set of children's health care quality measures (Child Core Set). Methods We conducted a multiple-case study of four high-performing states participating in the Children's Health Insurance Program Reauthorization Act (CHIPRA) Quality Demonstration Grant Program: Illinois, Maine, Pennsylvania, and Oregon. Cases were purposively selected for their diverse measurement approaches and used data from 2010 to 2015, including 154 interviews, semiannual grant progress reports, and annual public reports on Child Core Set measures.

Background: The patient-centered medical home (PCMH) is widely promoted as a model to improve the quality of primary care and lead to more efficient use of health care services. Few studies have examined the relationship between PCMH implementation at the practice level and health care utilization by children. Existing studies show mixed results.

Unlabelled: Objectives To evaluate the psychometric properties of the Microbicide Use Self-Efficacy (MUSE) instrument and to examine correlates of self-efficacy to use vaginal microbicides among a sample of racially and ethnically diverse women living in the north-eastern United States.

Methods: Exploratory and confirmatory factor analytic methods were used to explore and determine the dimensionality and psychometric properties of the MUSE instrument. Construct validity was assessed by examining the relationships of the MUSE instrument to key sexual behaviour, partner communication, relationship and psychosocial variables.

In vitro fertilization (IVF) has become a standard treatment for subfertility after it was demonstrated to be of value to humans in 1978. However, the introduction of IVF into mainstream clinical practice has been accompanied by concerns regarding the number of multiple gestations that it can produce, as multiple births present significant medical consequences to mothers and offspring. When considering IVF as a treatment modality, a balance must be set between the chance of having a live birth and the risk of having a multiple birth.

Perinatal depression is a prevalent and detrimental condition. Determining modifiable factors associated with it would identify opportunities for prevention. This paper: 1) identifies depressive symptom trajectories and heterogeneity in those trajectories during pregnancy through the first-year postpartum, and 2) examines the association between unintended pregnancy and depressive symptoms.

The role of maternal stress during pregnancy remains a focus of academic and clinical inquiry, yet there are few instruments available that measure pregnancy-specific contributors to maternal psychological state. This report examines the psychometric properties of an abbreviated version of the Pregnancy Experience Scale (PES) designed to evaluate maternal appraisal of positive and negative stressors during pregnancy. The PES-Brief consists of the top 10 items endorsed as pregnancy hassles and 10 pregnancy uplifts from the original scale.

Objective: To investigate women's willingness to use vaginal microbicides to reduce/prevent HIV infection, using measures grounded in the individual, behavioral, and social contexts of sex.

Design: A cross-sectional study that enrolled a sample (N = 531) of 18-55 year old Latina, African-American, and White women in the U.S.

In the context of a measurement development study designed to contextualize microbicide acceptability, a sample that represented a range of at-risk women and maintained the statistical power needed for validity analyses was required. A non-proportional quota sampling strategy focused on race/ethnicity and number of sexual partners was utilized. This strategy resulted in enrollment of approximately equal proportions of Latina (31%), Black (36%), and White (32%) women, and an approximately 1:2 ratio of single-partnered (29%) and multi-partnered (71%) women.

Background: Along with efficacy, a microbicide's acceptability will be integral to its impact on the pandemic. Understanding Product Characteristics that users find most acceptable and determining who will use which type of product are key to optimizing use effectiveness.

Objectives: To evaluate psychometrically the Important Microbicide Characteristics (IMC) instrument and examine its relationship to willingness to use microbicides.
