Optimizing Cefazolin Prophylaxis in Obstetrical Patients with Reported Beta-Lactam Allergy Undergoing Cesarean Delivery.

OBJECTIVES: Evaluate the impact of an allergy history-guided algorithm for optimizing perioperative cefazolin use in patients with reported beta-lactam allergy undergoing cesarean delivery. METHODS: The Allergy Clarification for Cefazolin Evidence-based Prescribing Tool (ACCEPT) was developed through consensus by allergists, anesthesiologists, and infectious diseases specialists, and implemented over a 2-month period (December 1, 2018, to January 31, 2019). A segmented regression on monthly cefazolin use was conducted during the baseline (January 1 to November 30, 2018) and intervention (February 1 to December 31, 2019) periods to evaluate the impact of ACCEPT on the monthly use of perioperative cefazolin in patients with reported beta-lactam allergy undergoing cesarean delivery. The frequency of perioperative allergic reactions and surgical site infections was collected during both periods. RESULTS: Of the 3128 eligible women who underwent a cesarean delivery, 282 (9%) reported a beta-lactam allergy. The most common beta-lactam allergens were penicillin (64.3%), amoxicillin (16.0%), and cefaclor (6.0%). The most frequently reported allergic reactions were rash (38.1%), hives (21.4%), and unknown (11.6%). Use of cefazolin increased from 52% (baseline) to 87% during the intervention period. Segmented regression analysis confirmed a statistically significant increase following implementation (incidence rate ratio 1.62, 95% CI 1.19-2.21, P = 0.002). There was 1 perioperative allergic reaction in the baseline period and 2 during the intervention period. Cefazolin use remained high (92%) 2 years after algorithm implementation. CONCLUSIONS: Implementation of a simple allergy history-guided algorithm in obstetrical patients with reported beta-lactam allergy resulted in a sustained increase in perioperative cefazolin prophylaxis.

Leveraging Mobile-Based Sensors for Clinical Research to Obtain Activity and Health Measures for Disease Monitoring, Prevention, and Treatment.

Clinical researchers are using mobile-based sensors to obtain detailed and objective measures of the activity and health of research participants, but many investigators lack expertise in integrating wearables and sensor technologies effectively into their studies. Here, we describe the steps taken to design a study using sensors for disease monitoring in older adults and explore the benefits and drawbacks of our approach. In this study, the Geriatric Acute and Post-acute Fall Prevention Intervention (GAPcare), we created an iOS app to collect data from the Apple Watch's gyroscope, accelerometer, and other sensors; results of cognitive and fitness tests; and participant-entered survey data. We created the study app using ResearchKit, an open-source framework developed by Apple for medical research that includes neuropsychological tests (e.g., of executive function and memory), gait speed, balance, and other health assessments. Data is transmitted via an Application Programming Interface (API) from the app to REDCap for researchers to monitor and analyze in real-time. Employing the lessons learned from GAPcare could help researchers create study-tailored research apps and access timely information about their research participants from wearables and smartphone devices for disease prevention, monitoring, and treatment.

Strategies to Ensure Continuity of Care Using Telemedicine with Older Adults during COVID-19: A Qualitative Study of Physicians in Primary Care and Geriatrics.

Objectives: Our objective was to interview primary care physicians (PCPs) and geriatricians on their experiences using telemedicine during the COVID-19 pandemic to examine strategies used to maintain continuity of care with their patients, ages 65 and older. Methods: Using purposive sampling, we selected physicians based on community size (metro/suburban/rural) and practice setting (academic/community) and conducted semi-structured interviews via Zoom (mean: 30 minutes). Interviews were recorded, transcribed, coded, and analyzed using framework analysis. Results: We enrolled 33 physicians (15 PCPs and 18 geriatricians) from July to November 2020. Findings indicate that many physicians successfully bridged the digital divide by: assessing patients' technological readiness in advance, being flexible with telehealth modes, using available home or facility-based staff, educating patients on telehealth privacy and usefulness, making accommodations for disabilities, and involving caregivers. Discussion: These findings can inform future policy and practice and assist physicians in resolving addressable barriers to telehealth use among older patients.

Transitioning to telehealth? A guide to evaluating outcomes.

Objectives: Telehealth use has surged since the onset of the coronavirus disease 2019 (COVID-19) pandemic, but the evaluation of telehealth outcomes and performance has not necessarily matched the pace of its uptake. In this article we aim to guide the design of a telehealth evaluation system encompassing all four domains of the outcome measurement framework developed by the National Quality Forum (NQF) - access to care, cost, experience, and effectiveness. We aim to achieve this through proposing survey items that can be distributed to patients or clinicians as a questionnaire and providing suggestions on areas of focus for evaluation studies. Methods: Using PubMed and Google Scholar search engines, we performed a literature review of articles related to the evaluation of telehealth outcomes that were published in English since 2000. Results: We found existing survey tools to assist the development of an evaluation questionnaire, and categorized items into the four NQF outcome domains. For each outcome domain, we also summarize existing work on evaluation and make recommendations on areas for future assessment. In particular, we found that telehealth accessibility and accommodations have been historically under-studied and provide tools to address this. Conclusions: Evaluating telehealth outcomes is critical to ensure efficient and high-quality care delivery, and we believe establishing an evaluation system will help practices assess and improve their telehealth systems as well as their ability to use telehealth to respond to the diverse needs of patients. Public Interest Summary: Since the start of the coronavirus disease 2019 (COVID-19) pandemic, telehealth use has been on the rise. Evaluating outcomes related to telehealth is critically important, but given the urgency of telehealth uptake, many health systems and practices may not yet have evaluation systems in place. This article guides the design of a telehealth evaluation system by proposing several validated and novel survey questions that can be used as part of a patient or clinician questionnaire and suggesting important measures of outcome for evaluation studies to assess across the four domains of telehealth quality as outlined by the National Quality Forum (NQF) - access to care, cost, experience, and effectiveness. We present tools to reach priority populations who often lack access to remote care, including older adults, underrepresented minorities, and people with disabilities.

Emergency physician perspectives on using telehealth with older adults during COVID-19: A qualitative study.

OBJECTIVES: Emergency medicine physicians have played a pivotal role throughout the coronavirus disease 19 (COVID-19) pandemic through in-person and remote management and treatment. Our primary objectives were to understand emergency medicine physicians' experiences using telehealth throughout the pandemic, any facilitators/barriers to successful usage, lessons learned during implementation, and successful/abandoned strategies used to engage with older adults. METHODS: Using a semi-structured interview guide, we conducted 30-min interviews. We used purposeful sampling to recruit emergency medicine physicians from all United States regions, rural-urban settings, and academic and community practices, who reported caring for patients 65 years or older in-person or virtually during the pandemic. Interviews were audio-recorded, transcribed, double-coded, and analyzed for emergent themes using framework analysis. RESULTS: A total of 15 in-depth interviews were completed from September to November 2020. Physicians had a median age of 37 years, 7 were women, and 9 had experience with telehealth before the pandemic. We identified several themes: (1) there were various motivations for telehealth use; (2) telehealth was used primarily to supplement, not replace in-person care; (3) most platforms were easy to use; (4) patients and caregivers had high acceptability of telemedicine; and (5) older adults with sensory and cognitive impairments often relied on caregivers. Emergency medicine physicians played a critical role during primary care office closures during the first wave-dispelling misinformation about COVID-19, triaging patients to testing and treatment, and providing care that would otherwise have been deferred. CONCLUSIONS: Our data show that telemedicine gained acceptability among emergency medicine physicians and provided options to patients who may have otherwise deferred care. These findings can inform future healthcare delivery for acute care needs or pandemic responses.

Telehealth was beneficial during COVID-19 for older Americans: A qualitative study with physicians.

BACKGROUND: Individuals aged 65 and older face unique barriers to adoption of telehealth, and the coronavirus disease 2019 pandemic has provided a "natural experiment" in how to meet the health needs of older patients remotely. Physician perspectives on practical considerations surrounding telehealth adoption, motivations of use, and reasons for nonuse are necessary to inform the future of healthcare delivery. The objective is to understand the experiences of physicians using telemedicine for older patients. METHODS: From September to November 2020, we conducted 30-min semi-structured interviews using purposeful sampling to identify and enroll participants from diverse settings. We included 48 U.S.-based physicians (geriatrician, n = 18, primary care, n = 15, emergency, n = 15) from all geographic regions, rural-urban and academic/community settings. Audio-recorded interviews were professionally transcribed and analyzed using framework analysis. Major themes and subthemes were identified. RESULTS: Participants had a median (interquartile range) age of 37.5 (34-44.5), 27 (56%) were women. Five major themes emerged: (1) telehealth uptake was rapid and iterative, (2) telehealth improved the safety of medical care, (3) use cases were specialty-specific (for geriatricians and primary care physicians telehealth substituted for in-person visits; for emergency physicians it primarily supplemented in-person visits), (4) physicians altered clinical care to overcome older patient barriers to telehealth use, and (5) telehealth use among physicians declined in mid-April 2020, due primarily to patient needs and administrator preferences, not physician factors. CONCLUSION: In this qualitative analysis, physicians reported a rapid, iterative uptake of telehealth and attenuation of use as coronavirus disease 2019 prevalence declined. Physician experiences during the pandemic can inform interventions and policies to help buoy telehealth for ongoing healthcare delivery and ensure its accessibility for older Americans.

A Single Site Phosphorylation on Hsp82 Ensures Cell Survival during Starvation in Saccharomyces cerevisiae.

Unicellular organisms live under diverse stressful conditions and must respond and adapt quickly to these stresses. When these stresses persist, cells favor a transition to quiescence. There are changes to many processes when cells begin their entry into quiescence. It has been reported that Hsp82 plays an important role in several such processes, and its distribution and activity change according to nutrient conditions. In this study, we found that the subcellular distribution of Hsp82 is regulated by its co-chaperone Ppt1. Under starvation conditions, Ppt1 expression was significantly reduced by a TOR-independent pathway. Furthermore, we found that Ppt1 regulates Hsp82 distribution in the cytoplasm and nucleus by dephosphorylating the S485 residue on Hsp82. The Hsp82S485A strain has impaired membrane-related protein transport, and its cell size did not become larger in quiescence compared to log phase, resulting in failure to survive during starvation.

Pulmonary rehabilitation in lung transplant candidates.

BACKGROUND: While awaiting lung transplantation, candidates may participate in pulmonary rehabilitation to improve their fitness for surgery. However, pulmonary rehabilitation outcomes have not been systematically evaluated in lung transplant candidates. METHODS: This investigation was a retrospective cohort study of 345 pre-transplant pulmonary rehabilitation participants who received a lung transplant between January 2004 and June 2009 and had available pre-transplant exercise data. Data extracted included: 6-minute walk tests at standard intervals; exercise training details; health-related quality-of-life (HRQL) measures; and early post-transplant outcomes. Paired t-tests were used to examine changes in the 6MW distance (6MWD), exercise training volume and HRQL during the pre-transplant period. We evaluated the association between pre-transplant 6MWD and transplant hospitalization outcomes. RESULTS: The final 6MWD prior to transplantation was only 15 m less than the listing 6MWD (n = 200; p = 0.002). Exercise training volumes increased slightly from the start of the pulmonary rehabilitation program until transplant: treadmill, increase 0.69 ml/kg/min (n = 238; p < 0.0001); biceps resistance training, 18 lbs. × reps (n = 286; p < 0.0001); and quadriceps resistance training, 15 lbs. × reps (n = 278; p < 0.0001). HRQL measures declined. A greater final 6MWD prior to transplant correlated with a shorter length of stay in the hospital (n = 207; p = 0.003). CONCLUSIONS: Exercise capacity and training volumes are well preserved among lung transplant candidates participating in pulmonary rehabilitation, even in the setting of severe, progressive lung disease. Participants with greater exercise capacity prior to transplantation have more favorable early post-transplant outcomes.
