Background Translating evidence-based interventions from study conditions to actual practice necessarily requires adaptation. We implemented an evidence-based Hospital at Home (HaH) intervention and evaluated whether adaptations could avoid diminished benefit from “voltage drop” (decreased benefit when interventions are applied under more heterogeneous conditions than existing in studies) or “program drift.” (decreased benefit arising from deviations from study protocols). Methods Patients were enrolled in HaH over a 6-month pilot period followed by nine quarters of implementation activity. The program retained core components of the original evidence-based HaH model, but adaptations were made at inception and throughout the implementation. These adaptations were coded as to who made them, what was modified, for whom the adaptations were made, and the nature of the adaptations. We collected information on length of stay (LOS), 30-day readmissions and emergency department (ED) visits, escalations to the hospital, and patient ratings of care. Outcomes were assessed by quarter of admission. Selected outcomes were tracked and fed back to the program leadership. We used logistic or linear regression with an independent variable included for the numerical quarter of enrollment after the initial 6-month pilot phase. Models controlled for season and for patient characteristics. Results Adaptations were made throughout the implementation period. The nature of adaptations was most commonly to add or to substitute new program elements. HaH services substituting for a hospital stay were received by 295 patients (a mean of 33, range 11–44, per quarter). A small effect of quarter from program inception was seen for escalations (OR 1.09, 95% CI 1.01 to 1.18, p  = 0.03), but no effect was observed for LOS (− 0.007 days/quarter; SE 0.02, p  = 0.75), 30 day ED visit (OR 0.93, 95% CI 0.86 to 1.01, p  = 0.09), 30-day readmission (OR 1.00, 95% CI 0.93 to 1.08, p  = 0.99), or patient rating of overall hospital care (OR for highest overall rating 0.99, 95% CI 0.93 to 1.05, p  = 0.66). Conclusions We made adaptations to HaH at inception and over the course of implementation. Our findings indicate that adaptations to evidence-based programs may avoid diminished benefits due to potential ‘program drift’ or ‘voltage drop.’ Trial registration Not applicable. This study is not a clinical trial by the International Committee of Medical Journal Editors (ICMJE) definition because it is an observational study “in which the assignment of the medical intervention is not at the discretion of the investigator.”

Background The growing population of patients over the age of 65 faces particular vulnerability following discharge after hospitalization or an emergency room visit. Specific areas of concern include a high risk for falls and poor comprehension of discharge instructions. Emergency medical technicians (EMTs), who frequently transport these patients home from the hospital, are uniquely positioned to aid in mitigating transition of care risks and are both trained and utilized to do so using the Transport PLUS intervention. Methods Existing literature and focus groups of various stakeholders were utilized to develop two checklists: the fall safety assessment (FSA) and the discharge comprehension assessment (DCA). EMTs were trained to administer the intervention to eligible patients in the geriatric population. Using data from the checklists, follow-up phone calls, and electronic health records, we measured the presence of hazards, removal of hazards, the presence of discharge comprehension issues, and correction or reinforcement of comprehension. These results were validated during home visits by community health workers (CHWs). Feasibility outcomes included patient acceptance of the Transport PLUS intervention and accuracy of the EMT assessment. Qualitative feedback via focus groups was also obtained. Clinical outcomes measured included 3-day and 30-day readmission or ED revisit. Results One-hundred three EMTs were trained to administer the intervention and participated in 439 patient encounters. The intervention was determined to be feasible, and patients were highly amenable to the intervention, as evidenced by a 92% and 74% acceptance rate of the DCA and FSA, respectively. The majority of patients also reported that they found the intervention helpful (90%) and self-reported removing 40% of fall hazards; 85% of such changes were validated by CHWs. Readmission/revisit rates are also reported. Conclusions The Transport PLUS intervention is a feasible, easily implemented tool in preventative community paramedicine with high levels of patient acceptance. Further study is merited to determine the effectiveness of the intervention in reducing rates of readmission or revisit. A randomized control trial has since begun utilizing the knowledge gained within this study.

There has been a significant increase in the implementation and dissemination of geriatric emergency department (GED) programs. Understanding the costs associated with patient care would yield insight into the direct financial value for patients, hospitals, health systems, and payers. To evaluate the association of GED programs with Medicare costs per beneficiary. This cross-sectional study included data on Medicare fee-for-service beneficiaries at 2 hospitals implementing Geriatric Emergency Department Innovations in Care Through Workforce, Informatics, and Structural Enhancement (GEDI WISE) (Mount Sinai Medical Center [MSMC] and Northwestern Memorial Hospital [NMH]) from January 1, 2013, to November 30, 2016. Analyses were conducted and refined from August 28, 2018, to November 20, 2020, using entropy balance to account for observed differences between the treatment and comparison groups. Treatment included consultation with a transitional care nurse (TCN) or a social worker (SW) trained for the GEDI WISE program at a beneficiary's first ED visit (index ED visit). The comparison group included beneficiaries who were never seen by either a TCN or an SW during the study period. The main outcome evaluated was prorated total Medicare payer expenditures per beneficiary over 30 and 60 days after the index ED visit encounter. Of the total 24 839 unique Medicare beneficiaries, 4041 were seen across the 2 EDs; 1947 (17.4%) at MSMC and 2094 (15.4%) at the NMH received treatment from either a GED TCN and/or a GED SW. The mean (SD) age of beneficiaries at MSMC was 78.8 (8.5) years and at NMH was 76.4 (7.7) years. Most patients at both hospitals were female (6821 [60.8%] at MSMC and 8023 [58.9%] at NMH) and White (7729 [68.9%] at MSMC and 9984 [73.3%] at NMH). Treatment was associated with statistically significant mean savings per beneficiary of $2436 (95% CI, $1760-$3111; P < .001) at one ED and $2905 (95% CI, $2378-$3431; P < .001) at the other ED in the 30 days after the index ED visit. The association between treatment and mean cumulative savings at 60 days after the index ED visit per beneficiary was also significant: $1200 (95% CI, $231-$2169; P = .02) at one ED and $3202 (95% CI, $2452-$3951; P < .001) at the other ED. Among Medicare fee-for-service beneficiaries, receipt of ED-based geriatric treatment by a TCN and/or an SW was associated with lower Medicare expenditures. These estimated cost savings may be used when calculating or considering the bundled value and potential reimbursement per patient for GED care programs.

In 2009 we described a geriatric service line or \"portfolio\" model of acute care-based models to improve care and reduce costs for high-cost Medicare beneficiaries with multiple chronic conditions. In this article we report the early results of the Medicare Innovations Collaborative, a collaborative program of technical assistance and peer-to-peer exchange to promote the simultaneous adoption of multiple complex care models by hospitals and health systems. We found that organizations did in fact adopt and implement multiple complex care models simultaneously; that these care models were appropriately integrated and adapted so as to enhance their adoptability within the hospital or health care system; and that these processes occurred rapidly, in less than one year. Members indicated that the perceived prestige of participation in the collaborative helped create incentives for change among their systems' leaders and was one of the top two reasons for success. The Medicare Innovations Collaborative approach can serve as a model for health service delivery change, ultimately expanding beyond the acute care setting and into the community and often neglected postacute and long-term care arenas to redesign care for high-cost Medicare beneficiaries.In 2009 we described a geriatric service line or \"portfolio\" model of acute care-based models to improve care and reduce costs for high-cost Medicare beneficiaries with multiple chronic conditions.

This chapter describes social work practice in geriatric care management settings. It considers contemporary challenges that arise in these settings, including definitional issues around what constitutes “care management” as opposed to “case management,” the need for culturally relevant services, and developing professional credentials and identification in a relatively new area of practice.

This chapter presents a case of 67‐year‐old woman who had increasing number of emergency department (ED) visits for shortness of breath. There are a number of evidence‐based transitional care programs designated to reduce hospital readmissions such as the Care Transitions Intervention, Project RED, and Project BOOST. When developing a specific transitional care model, the following elements must be considered: early engagement and assessment; in‐person or telephonic follow‐up; schedule of follow‐up; duration of intervention; staffing; and outcomes desired. Whether utilizing a nurse, nurse practitioner (NP), or social worker‐driven model of transitional care, there is a consensus on how to improve outcomes as patients transition between settings of care. The elements necessary in ED to home transitional care are those of a transitional care initiative currently being implemented and launched as part of an innovative model of care with Geriatric Emergency Department Innovations in care through workforce, informatics, and structural enhancements.

To compare synthetic oxytocin infusion regimens used during labour, calculate the International Units (IU) escalation rate and total amount of IU infused over eight hours. Observational study Twelve countries, eleven European and South Africa. National, regional or institutional-level regimens on oxytocin for induction and augmentation labour Data on oxytocin IU dose, infusion fluid amount, start dose, escalation rate and maximum dose were collected. Values for each regimen were converted to IU in 1000ml diluent. One IU corresponded to 1.67[mu]g for doses provided in grams/micrograms. IU hourly dose increase rates were based on escalation frequency. Cumulative doses and total IU amount infused were calculated by adding the dose administered for each previous hour. Main Outcome Measures Oxytocin IU dose infused Data were obtained on 21 regimens used in 12 countries. Details on the start dose, escalation interval, escalation rate and maximum dose infused were available from 16 regimens. Starting rates varied from 0.06 IU/hour to 0.90 IU/hour, and the maximum dose rate varied from 0.90 IU/hour to 3.60 IU/hour. The total amount of IU oxytocin infused, estimated over eight hours, ranged from 2.38 IU to 27.00 IU, a variation of 24.62 IU and an 11-fold difference. Current variations in oxytocin regimens for induction and augmentation of labour are inexplicable. It is crucial that the appropriate minimum infusion regimen is administered because synthetic oxytocin is a potentially harmful medication with serious consequences for women and babies when inappropriately used. Estimating the total amount of oxytocin IU received by labouring women, alongside the institution's mode of birth and neonatal outcomes, may deepen our understanding and be the way forward to identifying the optimal infusion regimen.

Cell surface receptors, ligands, and adhesion molecules underlie development, circuit formation, and synaptic function of the central nervous system and represent important therapeutic targets for many neuropathologies. The functional contributions of interactions between cell surface proteins of neurons and nonneuronal cells have not been fully addressed. Using an unbiased protein-protein interaction screen, we showed that the human immunomodulatory ligand B7-1 (hB7-1) interacts with the p75 neurotrophin receptor (p75NTR) and that the B7-1:p75NTR interaction is a recent evolutionary adaptation present in humans and other primates, but absent in mice, rats, and other lower mammals. The surface of hB7-1 that engages p75NTR overlaps with the hB7-1 surface involved in CTLA-4/CD28 recognition, and these molecules directly compete for binding to p75NTR. Soluble or membrane-bound hB7-1 altered dendritic morphology of cultured hippocampal neurons, with loss of the postsynaptic protein PSD95 in a p75NTR-dependent manner. Abatacept, an FDA-approved therapeutic (CTLA-4-hFc fusion) inhibited these processes. In vivo injection of hB7-1 into the murine subiculum, a hippocampal region affected in Alzheimer's disease, resulted in p75NTR-dependent pruning of dendritic spines. Here, we report the biochemical interaction between B7-1 and p75NTR, describe biological effects on neuronal morphology, and identify a therapeutic opportunity for treatment of neuroinflammatory diseases.

The term diabetic cardiomyopathy (DCM) labels an abnormal cardiac structure and performance due to intrinsic heart muscle malfunction, independently of other vascular co-morbidity. DCM, accounting for 50%–80% of deaths in diabetic patients, represents a worldwide problem for human health and related economics. Optimal glycemic control is not sufficient to prevent DCM, which derives from heart remodeling and geometrical changes, with both consequences of critical events initially occurring at the cardiomyocyte level. Cardiac cells, under hyperglycemia, very early undergo metabolic abnormalities and contribute to T helper (Th)-driven inflammatory perturbation, behaving as immunoactive units capable of releasing critical biomediators, such as cytokines and chemokines. This paper aims to focus onto the role of cardiomyocytes, no longer considered as “passive” targets but as “active” units participating in the inflammatory dialogue between local and systemic counterparts underlying DCM development and maintenance. Some of the main biomolecular/metabolic/inflammatory processes triggered within cardiac cells by high glucose are overviewed; particular attention is addressed to early inflammatory cytokines and chemokines, representing potential therapeutic targets for a prompt early intervention when no signs or symptoms of DCM are manifesting yet. DCM clinical management still represents a challenge and further translational investigations, including studies at female/male cell level, are warranted.
