Objective: When people receive information about the benefits and harms of mammography screening, they do not always accept it at face value and instead express skepticism. The purpose of this research was to identify the psychological drivers of this skepticism. Two theory-driven hypotheses were considered: One hypothesis proposes that skeptical reactions reflect a psychological defense against information that is emotionally aversive.

Article Synopsis
  • This study investigates how well electronic health records at UCHealth capture data on sexual orientation and gender identity (SOGI) among older adults aged 55 and over from 2019 to 2022.
  • The analysis found that a staggering majority of SOGI data was missing, with 93% for sexual orientation and 96% for gender identity, leading to only 0.005% of older adults being identifiable as sexual or gender minorities.
  • The authors highlight the importance of improving SOGI data collection to better recognize and meet the healthcare needs of sexual and gender minority older adults, remarking that current estimates suggest they represent 7%-11% of the broader population.

Purpose: Overdiagnosis is a concept central to making informed breast cancer screening decisions, and yet some people may react to overdiagnosis with doubt and skepticism. The present research assessed 4 related reactions to overdiagnosis: reactance, self-exemption, disbelief, and source derogation (REDS). The degree to which the concept of overdiagnosis conflicts with participants' prior beliefs and health messages (information conflict) was also assessed as a potential antecedent of REDS.

Background: Shared decision making (SDM) is gaining importance in cardiology, including Centers for Medicare & Medicaid Services (CMS) reimbursement policies requiring documented SDM for patients considering primary prevention implantable cardioverter defibrillators. The DECIDE-ICD Trial (Decision Support Intervention for Patients offered implantable Cardioverter-Defibrillators) assessed the implementation and effectiveness of patient decision aids (DAs) using a stepped-wedge design at 7 sites. The purpose of this subanalysis was to qualitatively describe electrophysiology clinicians' experience implementing and using the DAs.

Colorectal cancer (CRC) incidence and mortality are rising in individuals under age 50, termed early age onset (EAO) CRC. Lower endoscopy is recommended for all patients with unexplained iron deficiency anemia (IDA) or hematochezia to assess the EAO-CRC. For those without symptoms, professional societies recommend decreasing the age to start screening from 50 to 45.

Shared decision making (SDM) facilitates delivery of medical therapies that are in alignment with patients' goals and values. Medicare national coverage decision for several interventions now includes SDM mandates, but few have been evaluated in nationwide studies. Based upon a detailed needs assessment with diverse stakeholders, we developed pamphlet and video patient decision aids (PtDAs) for implantable cardioverter/defibrillator (ICD) implantation, ICD replacement, and cardiac resynchronization therapy with defibrillation to help patients contemplate, forecast, and deliberate their options.

Background: Although decades of research support hypertension treatment, studies guiding the successful implementation of programs to control blood pressure (BP) in real-world primary care settings are sparse.

Methods: In this study a multicomponent intervention was implemented, with the following goals: (1) achieve 70% control of hypertension within 18 months, (2) use the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework to evaluate the implementation of the program, and (3) assess additional actions that could have been undertaken to achieve control among those who remained uncontrolled.

Results: Of 786 patients, 597 achieved BP control (75.

Purpose: De-implementation of low-value services among patients with limited life expectancy is challenging. Robust mortality prediction models using routinely collected health care data can enhance health care stakeholders' ability to identify populations with limited life expectancy. We developed and validated a claims-based prediction model for 5-year mortality using regularized regression methods.

Background: Treatment decisions commonly have to be made in intensive care units (ICUs). These decisions are difficult for surrogate decision makers and often lead to decisional conflict, psychological distress, and treatments misaligned with patient preferences.

Objective: To determine whether a decision aid about prolonged mechanical ventilation improved prognostic concordance between surrogate decision makers and clinicians compared with a usual care control.

Article Synopsis
  • Guidelines for colorectal cancer screening emphasize personalized approaches for older adults, focusing on life expectancy and cancer risk, but little is known about patient perspectives on these recommendations.
  • A survey conducted with veterans over 50 who previously had normal colonoscopies aimed to explore their comfort with stopping low-value CRC screening based on potential health benefits.
  • Out of 1,415 potential respondents, 74.5% completed the survey; results indicated that many veterans were uncomfortable with ending low-value screenings and felt that age and life expectancy calculators should not dictate screening decisions.

Background: Colorectal cancer (CRC) is the second leading cause of cancer-related deaths in the United States; however, CRC screening reduces both incidence and mortality rates. Patient decision aids (DAs) are an evidence-based strategy to support patients making health-related decisions. CRC screening DAs can be unsuccessful due to provider preferences for colonoscopy and lack of effective DA implementation strategies within clinical settings.
