Health Care Contact Days Among Older Cancer Survivors.

Purpose: Health care contact days-days spent receiving health care outside the home-represent an intuitive, practical, and person-centered measure of time consumed by health care.

Methods: We linked 2019 Medicare Current Beneficiary Survey and traditional Medicare claims data for community-dwelling older adults with a history of cancer. We identified contact days (ie, spent in a hospital, emergency department, skilled nursing facility, or inpatient hospice or receiving ambulatory care including an office visit, procedure, treatment, imaging, or test) and described patterns of total and ambulatory contact days.

Healthcare contact days among older adults living with dementia.

Background: For older adults with dementia and their care partners, accessing health care outside the home involves substantial time, direct and indirect costs, and other burdens. While prior studies have estimated days spent by these individuals in or out of hospitals and nursing homes, ambulatory care burdens are likely substantial yet poorly understand. Therefore, we characterized "health care contact days"-days spent receiving ambulatory or institutional care-in this population.

Health Care Contact Days Among Older Adults in Traditional Medicare : A Cross-Sectional Study.

Background: Days spent obtaining health care outside the home can represent not only access to needed care but also substantial time, effort, and cost, especially for older adults and their care partners. Yet, these "health care contact days" have not been characterized.

Objective: To assess composition of, variation and patterns in, and factors associated with contact days among older adults.

Effect of a Peer Comparison and Educational Intervention on Medical Test Conversation Quality: A Randomized Clinical Trial.

Importance: Medical test overuse and resulting care cascades represent a costly, intractable problem associated with inadequate patient-clinician communication. One possible solution with potential for broader benefits is priming routine, high-quality medical test conversations.

Objective: To assess if a peer comparison and educational intervention for physicians and patients improved medical test conversations during annual visits.

A closed cycle for esterifying aromatic hydrocarbons with CO and alcohol.

The ability to functionalize hydrocarbons with CO could create opportunities for high-volume CO utilization. However, current methods to form carbon-carbon bonds between hydrocarbons and CO require stoichiometric consumption of very resource-intensive reagents to overcome the low reactivity of these substrates. Here, we report a simple semi-continuous cycle that converts aromatic hydrocarbons, CO and alcohol into aromatic esters without consumption of stoichiometric reagents.

CuH-Catalyzed Asymmetric Hydroamidation of Vinylarenes.

A CuH-catalyzed enantioselective hydroamidation reaction of vinylarenes has been developed using readily accessible 1,4,2-dioxazol-5-ones as electrophilic amidating reagents. This method provides a straightforward and efficient approach to synthesize chiral amides in good yields with high levels of enantiopurity under mild conditions. Moreover, this transformation tolerates substrates bearing a broad range of functional groups.
