: Prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT), in combination with magnetic resonance imaging (MRI), may enhance the diagnosis and staging of prostate cancer. Image fusion of separately acquired PET/CT and MRI images serve to facilitate clinical integration and treatment planning. This study aimed to investigate different PSMA PET/CT and MRI image fusion workflows for prostate cancer visualisation.

Objective: The Certified Community Behavioral Health Clinic (CCBHC) demonstration is designed to increase access to comprehensive ambulatory care and crisis services, which may reduce emergency department (ED) visits and hospitalizations. This study examined whether the demonstration had an impact on ED visits and hospitalizations in Missouri, Oklahoma, and Pennsylvania.

Methods: This difference-in-differences analysis used Medicaid claims data from 2015 to 2019 to examine service use during a 12-month baseline period and the first 24 months of the demonstration for beneficiaries who received care from CCBHCs and beneficiaries who received care from other behavioral health clinics in the same state, representing care as usual.

Introduction: Various adaptive radiation therapy (ART) methods have emerged, with little consensus amongst the literature as to which is most appropriate. This study aimed to compare dose mapping (DM) versus Monte Carlo recalculation (MCR), using cone beam computed tomography (CBCT) images when utilised in automated ART dose accumulation workflows in the MIM Maestro software package.

Methods: The treatment plans for 38 cancer patients (19 prostate and 19 head and neck cases) were used to perform DM or MCR retrospectively upon CBCTs acquired during treatment, which were then deformably registered to the planning CT (DR-pCT) to facilitate dose accumulation.

Unlabelled: T-cell immunoglobulin mucin family member 3 (Tim-3) is an immune checkpoint receptor that dampens effector functions and causes terminal exhaustion of cytotoxic T cells. Tim-3 inhibitors are under investigation in immuno-oncology (IO) trials, because blockade of T-cell-Tim-3 enhances antitumor immunity. Here, we identify an additional role for Tim-3 as a growth-suppressive receptor intrinsic to melanoma cells.

Intra-oral stents (including mouth-pieces and bite blocks) can be used to displace adjacent non-involved oral tissue and reduce radiation side effects from radiotherapy treatments for head-and-neck cancer. In this study, a modular and customisable 3D printed intra-oral stent was designed, fabricated and evaluated, to utilise the advantages of the 3D printing process without the interruption of clinical workflow associated with printing time. The stent design used a central mouth-opening and tongue-depressing main piece, with optional cheek displacement pieces in three different sizes, plus an anchor point for moulding silicone to fit individual patients' teeth.

Introduction: A challenge in implementing deformable image registration (DIR) in radiation therapy planning is effectively communicating registration accuracy to the radiation oncologist. This study aimed to evaluate the MIM® quality assurance (QA) tool for rating DIR accuracy.

Methods: Retrospective DIR was performed on CT images for 35 head and neck cancer patients.

Informed consent is necessary for all medical, surgical and obstetric interventions. Whilst informed consent can be obtained for elective procedures, it is much more challenging to obtain for emergency interventions. It can be difficult for women to understand the need for emergency intervention when pregnancy has been low risk.

Objective: Nearly 10% of all hospitalized children have a primary behavioral health diagnosis, but the effectiveness of treatment can be limited by caregivers' challenges navigating the behavioral health system. In this study, we assessed a novel peer-support intervention ("parent partners") designed for the caregivers of children admitted to an inpatient psychiatric unit.

Methods: We used a mixed-methods approach including 1) document review and interviews to assess implementation and 2) a difference-in-differences analysis using claims for Medicaid-enrolled children admitted to the intervention inpatient psychiatric unit and matched comparison children admitted to other inpatient psychiatric units to assess the impacts on health care use after discharge.

From 2012 to 2015, Sanford Health, a large health care system, integrated behavioral health services and chronic condition care management in some of its primary care practices in the Dakotas and rural Minnesota. Using difference-in-differences analyses for fee-for-service Medicare beneficiaries attributed to 22 participating practices and 91 matched comparison practices, we found that the program increased the receipt of four recommended diabetes care processes by 8.6% (p=.

Consumers prefer home and community-based long-term care (LTC) services (HCBS) but lack information on those services. We examined the use of community health workers (CHWs) to find and help Medicaid beneficiaries with unmet LTC needs access HCBS compared to standard HCBS outreach approaches. We found that CHWs were very effective at finding persons with greater needs and were better able to help them access a greater range of HCBS services.

Objectives: Medicare, Medicaid, and commercial plans have all explored ways to improve outcomes for patients with high costs and complex medical and social needs. The purpose of this study was to test the effectiveness of a high-intensity care management program that the Rutgers University Center for State Health Policy (CSHP) implemented as an adaptation of a promising model developed by the Camden Coalition of Healthcare Providers.

Study Design: We estimated the impact of the program on 6 utilization and spending outcomes for a subgroup of beneficiaries enrolled in Medicare fee-for-service (n = 149) and a matched comparison group (n = 1130).

Objectives: To provide actionable recommendations for improving care coordination programs for children with special healthcare needs (CSHCN) in Medicaid managed care.

Study Design: Literature review and interviews with stakeholders and policy experts to adapt lessons learned from Medicare care coordination programs for CSHCN in Medicaid managed care.

Methods: We reviewed syntheses of research on Medicare care coordination programs to identify lessons learned from successful programs.

Background: The Center for Medicare & Medicaid Innovation (CMMI) tests new models of paying for or delivering health care services and expands models that improve health outcomes while lowering medical spending. CMMI gave TransforMED, a national learning and dissemination contractor, a 3-year Health Care Innovation Award (HCIA) to integrate health information technology systems into physician practices. This paper estimates impacts of TransforMED's HCIA-funded program on patient outcomes and Medicare parts A and B spending.

Aim: This paper reports on a quality-improvement project to develop nursing documentation that reflects holistic care within a specialist palliative centre.

Background: The World Health Organization definition of palliative care includes impeccable assessment and management of pain and other symptoms. However, existing nursing documentation focuses mainly on the management of physical symptoms, with other aspects of nursing less frequently documented.

Importance: CareFirst, the largest commercial insurer in the mid-Atlantic Region of the United States, runs a medical home program focusing on financial incentives for primary care practices and care coordination for high-risk patients. From 2013 to 2015, CareFirst extended the program to Medicare fee-for-service (FFS) beneficiaries in participating practices. If the model extension improved quality while reducing spending, the Centers for Medicare and Medicaid Services could expand the program to Medicare beneficiaries broadly.

An issue in addressing racial healthcare disparities is the need to reduce, often unconscious, provider bias. Provider empathy can overcome such bias. Patient perceptions of provider empathy were explored to identify which provider behaviors patients perceived as conveying empathy and how perceived provider empathy influenced patient-provider interactions.
