Transitional care management (TCM) services after hospital discharge are critical for continuity of care, and the COVID-19 pandemic accelerated the shift to telehealth modes of delivery. This study examined the shift from face-to-face to telehealth care around the start of the pandemic (April-July 2020) compared with the same months in 2019 and 2021 and the corresponding 30-day readmission rates. We compared the rates of face-to-face and telehealth TCM as well as face-to-face and telehealth non-TCM services and observed a dramatic shift to telehealth in 2020 with a slight drop-off in 2021.

Importance: The 2018 Chronic Care Act allowed Medicare Advantage plans to have greater flexibility in offering supplemental benefits, such as meals and services, to address unmet needs of beneficiaries with certain chronic conditions. Based on earlier studies of community-based nutritional support, such programs may result in reduced use.

Objective: To evaluate the association of a 4-week posthospitalization home-delivered meals benefit with 30-day all-cause rehospitalization and mortality in patients admitted for heart failure (HF) and other acute medical conditions (non-HF).

Article Synopsis
  • Asian women immigrants in the USA experience high rates of domestic abuse but often do not disclose it due to significant psychosocial barriers.
  • The study identified five main barriers to disclosure: victim-blaming, beliefs in male dominance, familial and individual shame, and fear of consequences, particularly among Mandarin Chinese and Korean speakers.
  • Health providers' encouragement alone is not enough; instead, there is a need for anonymous counseling options and community awareness programs in Asian languages to help reduce stigma and misinformation.

Introduction: The Southern California region of Kaiser Permanente developed a COVID-19 Home Monitoring program as an alternative to hospital admission to decrease hospital bed days and mitigate the adverse effects of a surge. To date, more than 15,000 patients have been enrolled and approximately 10% of enrolled patients have been escalated to hospital care for timely treatment. Our objective is to describe our COVID-19 Home Monitoring program and present early results.

The immobilization of cellulose 3,5-dimethylphenyl carbamate and amylose 3,5-dimethylphenyl carbamate on silica gel carrier was achieved by using photochemical and thermal processes. Both approaches provide an easy access to materials which were applied as chiral stationary phases (CSPs) for the chromatographic resolution of racemic molecules. The influence of parameters such as irradiation time and solvent on immobilization effectiveness was investigated.

Background: Follow-up visits with clinic providers after hospital discharge may not be feasible for some patients due to functional limitations, transportation challenges, need for physical distancing, or fear of exposure especially during the current COVID-19 pandemic.

Methods: The aim of the study was to determine the effects of post-hospital clinic (POSH) and telephone (TPOSH) follow-up provider visits versus no visit on 30-day readmission. We used a retrospective cohort design based on data from 1/1/2017 to 12/31/2019 on adult patients (n = 213,513) discharged home from 15 Kaiser Permanente Southern California hospitals.

Article Synopsis
  • - Undergraduate students at UCLA conducted research using RNA interference (RNAi) and fluorescent proteins to pinpoint genes crucial for blood cell development in fruit flies, screening around 3,500 genes and finding 137 that affected hematopoiesis.
  • - By targeting RNAi to different cell types involved in blood cell maturation, the researchers identified specific gene subsets that either facilitate or inhibit this process, revealing new insights into gene functions related to RNA processing and vesicular trafficking.
  • - The CURE (Course-Based Undergraduate Research Experience) model not only enhanced students' understanding and skills in science but also improved retention rates in STEM fields, demonstrating the value of hands-on research in education.

Risks of intimate partner violence (IPV) often are higher among immigrant women, due to dependency, language barriers, deportation fears, cultural beliefs, and limited access to services. In the United States, Asian immigrant women experiencing IPV often are reluctant to disclose abuse. Viewing videos that depict IPV survivors who have successfully obtained help might encourage disclosure.

Objective: Integrated or collaborative care is a well-evidenced and widely practiced approach to improve access to high-quality mental health care in primary care and other settings. Psychiatrists require preparation for this emerging type of practice, and such training is now mandatory for Canadian psychiatry residents. However, it is not known how best to mount such training, and in the absence of such knowledge, the quality of training across Canada has suffered.

Article Synopsis
  • The study investigates how inpatient palliative care (IPC) impacts the quality of end-of-life care and healthcare usage among patients who died between 2012 and 2014 in Kaiser Permanente Southern California.
  • Patients who received IPC were more likely to enroll in home-based palliative care or hospice and were less likely to die in hospitals or intensive care units compared to those who did not receive IPC.
  • However, those receiving IPC had a higher chance of being rehospitalized and visiting emergency departments, suggesting that increased healthcare utilization may be influenced by existing patient needs rather than the care itself.

A process to immobilize -methylbenzoyl cellulose (PMBC) on silica gel has been developed and applied to prepare chiral stationary phases (CSPs) for enantioselective chromatography. The immobilization was achieved by simple irradiation of the polysaccharide derivative with ultraviolet light after coating on a silica gel support. The influence of parameters such as irradiation time and solvent on immobilization effectiveness were investigated.

Objectives: Pneumonia severity tools were primarily developed in cohorts of hospitalized patients, limiting their applicability to the emergency department (ED). We describe current community ED admission practices and examine the accuracy of the CURB-65 to predict 30-day mortality for patients, either discharged or admitted with community-acquired pneumonia (CAP).

Methods: A retrospective, observational study of adult CAP encounters in 14 community EDs within an integrated healthcare system.

In 2011, Kaiser Permanente Northwest Region (KPNW) won the Lawrence Patient Safety Award for its innovative work in reducing hospital readmission rates. In 2012, Kaiser Permanente Southern California (KPSC) won the Transfer Projects Lawrence Safety Award for the successful implementation of the KPNW Region's "transitional care" bundle to a Region that was almost 8 times the size of KPNW. The KPSC Transition in Care Program consists of 6 KPNW bundle elements and 2 additional bundle elements added by the KPSC team.

Purpose: To determine whether response to transarterial chemoembolization can predict survival in patients with hepatocellular carcinoma (HCC) who are candidates for orthotopic liver transplantation (LT) and if either European Association for Study of the Liver (EASL) criteria or Response Evaluation Criteria in Solid Tumors (RECIST) criteria are more accurate for this purpose.

Materials And Methods: A retrospective review of all patients who underwent LT after transarterial chemoembolization between January 2005 and June 2011 was performed. Follow-up imaging with multiphasic computed tomography or magnetic resonance imaging was performed 1 month after transarterial chemoembolization and every 3 months thereafter until LT.
