Video or Telephone? A Natural Experiment on the Added Value of Video Communication in Community Paramedic Responses.

STUDY OBJECTIVE: The objective of this study was to determine the effect of video versus telephonic communication between community paramedics and online medical control physicians on odds of patient transport to a hospital emergency department (ED). METHODS: This was a retrospective analysis of data from a telemedicine-capable community paramedicine program operating within an advanced illness management program that provides home-based primary care to approximately 2,000 housebound patients per year who have advanced medical illness, multiple chronic conditions, activities of daily living dependencies, and past-year hospitalizations. Primary outcome was difference in odds of ED transport between community paramedicine responses with video communication versus those with telephonic communication. Secondary outcomes were physicians' perception of whether video enhanced clinical evaluation and whether perceived enhancement affected ED transport. RESULTS: Of 1,707 community paramedicine responses between 2015 and 2017, 899 (53%) successfully used video; 808 (47%) used telephonic communication. Overall, 290 patients (17%) were transported to a hospital ED. In the adjusted regression model, video availability was not associated with a significant difference in the odds of ED transport (odds ratio 0.80; 95% confidence interval 0.62 to 1.03). Online medical control physicians reported that video enhanced clinical evaluation 85% of the time, but this perception was not associated with odds of ED transport. CONCLUSION: We found support that video is considered an enhancement by physicians overseeing a community paramedicine response, but is not associated with a statistically significant difference in transport to the ED compared with telephonic communication in this nonrandom sample. These results have implications for new models of out-of-hospital care that allow patients to be evaluated and treated in the home.

Acute, Post-acute, and Primary Care Utilization in a Home-Based Primary Care Program During COVID-19.

BACKGROUND AND OBJECTIVES: Older adults with multiple comorbidities experience high rates of hospitalization and poor outcomes from Coronavirus Disease 2019 (COVID-19). Changes in care utilization by persons in advanced illness management (AIM) programs during the COVID-19 pandemic are not well known. The purpose of this study was to describe changes in care utilization by homebound AIM patients in an epicenter of the COVID-19 pandemic before and during the pandemic. RESEARCH DESIGN AND METHODS: Descriptive statistics and tests of differences were used to compare care utilization rates, including emergency department (ED) and inpatient admissions, acute and subacute rehabilitation, and AIM program utilization during the pandemic with rates 1 year prior. RESULTS: Acute and post-acute utilization for enrollees (n = 1,468) decreased March-May 2020 compared to 1 year prior (n = 1,452), while utilization of AIM program resources remained high. Comparing 2019 and 2020, ED visits/1,000 enrollees were 109 versus 44 (p < .001), inpatient admissions 213 versus 113 (p < .001), and rehabilitation facility admissions 56 versus 31 (p = .014); AIM program home visits were 1,935 versus 276 (p < .001), remote visits (telehealth/telephonic) 0 versus 1,079 (p < .001), and all other phone touches 3,032 versus 5,062 (p < .001). Home hospice admissions/1,000 increased: 16-31 (p = .011). DISCUSSION AND IMPLICATIONS: Our results demonstrate decreased acute and post-acute utilization, while maintaining high levels of connectedness to the AIM program, among a cohort of homebound older adults during the COVID-19 pandemic compared with 1 year prior. While further study is needed, our results suggest that AIM programs can provide support to this population in the home setting during a pandemic.

Care Team Perspectives and Acceptance of Telehealth in Scaling a Home-Based Primary Care Program: Qualitative Study.

BACKGROUND: Novel and sustainable approaches to optimizing home-based primary care (HBPC) programs are needed to meet the medical needs of a growing number of homebound older adults in the United States. Telehealth may be a viable option for scaling HBPC programs. OBJECTIVE: The purpose of this qualitative study was to gain insight into the perspectives of HBPC staff regarding adopting telehealth technology to increase the reach of HBPC to more homebound patients. METHODS: We collected qualitative data from HBPC staff (ie, physicians, registered nurses, nurse practitioners, care managers, social workers, and medical coordinators) at a practice in the New York metropolitan area through 16 semistructured interviews and three focus groups. Data were analyzed thematically using the template analysis approach with Self-Determination Theory concepts (ie, relatedness, competence, and autonomy) as an analytical lens. RESULTS: Four broad themes-pros and cons of scaling, technology impact on staff autonomy, technology impact on competence in providing care, and technology impact on the patient-caregiver-provider relationship-and multiple second-level themes emerged from the analysis. Staff acknowledged the need to scale the program without diminishing effective patient-centered care. Participants perceived alerts generated from patients and caregivers using telehealth as potentially increasing burden and necessitating a rapid response from an already busy staff while increasing ambiguity. However, they also noted that telehealth could increase efficiency and enable more informed care provision. Telehealth could enhance the patient-provider relationship by enabling caregivers to be an integral part of the patient's care team. Staff members raised the concern that patients or caregivers might unnecessarily overutilize the technology, and that some home visits are more appropriate in person rather than via telehealth. CONCLUSIONS: These findings suggest the importance of considering the perspectives of medical professionals regarding telehealth adoption. A proactive approach exploring the benefits and concerns professionals perceive in the adoption of health technology within the HBPC program will hopefully facilitate the optimal integration of telehealth innovations.

Providing Acute Care at Home: Community Paramedics Enhance an Advanced Illness Management Program-Preliminary Data.

Models addressing urgent clinical needs for older adults with multiple advanced chronic conditions are lacking. This observational study describes a Community Paramedicine (CP) model for treatment of acute medical conditions within an Advanced Illness Management (AIM) program, and compares its effect on emergency department (ED) use and subsequent hospitalization with that of traditional emergency medical services (EMS). Community paramedics were trained to evaluate and, with telemedicine-enhanced physician guidance, treat acute illnesses in individuals' homes. They were also able to transport to the ED if needed. The CP model was implemented between January 1, 2014, and April 30, 2015 in a suburban-urban AIM program. Participants included 1,602 individuals enrolled in the AIM program with high rates of dementia, decubitus ulcers, diabetes mellitus, congestive heart failure, and chronic obstructive pulmonary disease. Participants had a median age of 83 and an average of five activity of daily living dependencies (range 0-6). During the study period, there were 664 CP responses and 1,091 traditional EMS transports to the ED among 773 individuals. Only 22% of CP responses required transport; 78% were evaluated and treated in the home. Individuals that community paramedics transported to the ED had higher rates of hospitalization (82.2%) than those using traditional EMS (68.9%) (P < .001). Post-CP surveys showed that all respondents felt the program was of high quality. Results support the potential benefits of CP and invite further evaluation of this innovative care model.

Improving transitions of care from hospital to home: what works?

As the cost of care rises and fragmentation of health care increases, care transitions have become critical parts of the health care system. Physicians and other inpatient providers have the responsibility to communicate to subsequent providers, but such communication occurs far less than is optimal. Timely discharge summaries for the next-level provider, postdischarge phone calls to patients, and postdischarge follow-up appointments with primary-care physicians or inpatient providers may improve postdischarge health care utilization. Pharmacists may also reduce medication errors, adverse medication events, and even readmissions. The most promising data, however, come from studies of multidisciplinary approaches, some of which have shown large reductions in postdischarge utilization and costs. More study is needed to pinpoint the most cost-effective and efficient strategies to improve transitions from the inpatient setting to other settings.

Cochlear implants and ex vivo BDNF gene therapy protect spiral ganglion neurons.

Spiral ganglion neurons often degenerate in the deaf ear, compromising the function of cochlear implants. Cochlear implant function can be improved by good preservation of the spiral ganglion neurons, which are the target of electrical stimulation by the implant. Brain derived neurotrophic factor (BDNF) has previously been shown to enhance spiral ganglion survival in experimentally deafened ears. Providing enhanced levels of BDNF in human ears may be accomplished by one of several different methods. The goal of these experiments was to test a modified design of the cochlear implant electrode that includes a coating of fibroblast cells transduced by a viral vector with a BDNF gene insert. To accomplish this type of ex vivo gene transfer, we transduced guinea pig fibroblasts with an adenovirus with a BDNF gene cassette insert, and determined that these cells secreted BDNF. We then attached BDNF-secreting cells to the cochlear implant electrode via an agarose gel, and implanted the electrode in the scala tympani. We determined that the BDNF expressing electrodes were able to preserve significantly more spiral ganglion neurons in the basal turns of the cochlea after 48 days of implantation when compared to control electrodes. This protective effect decreased in the higher cochlear turns. The data demonstrate the feasibility of combining cochlear implant therapy with ex vivo gene transfer for enhancing spiral ganglion neuron survival.

The fate of outer hair cells after acoustic or ototoxic insults.

In epithelial sheets, clearance of dead cells may occur by one of several routes, including extrusion into the lumen, phagocytic clearance by invading lymphocytes, or phagocytosis by neighboring cells. The fate of dead cochlear outer hair cells is unclear. We investigated the fate of the "corpses" of dead outer hair cells in guinea pigs and mice following drug or noise exposure. We examined whole mounts and plastic sections of normal and lesioned organ of Corti for the presence of prestin, a protein unique to outer hair cells. Supporting cells, which are devoid of prestin in the normal ear, contained clumps of prestin in areas of hair cell loss. The data show that cochlear supporting cells surround the corpses and/or debris of degenerated outer hair cells, and suggest that outer hair cell remains are phagocytosed by supporting cells within the epithelium.

Auditory hair cell replacement and hearing improvement by Atoh1 gene therapy in deaf mammals.

In the mammalian auditory system, sensory cell loss resulting from aging, ototoxic drugs, infections, overstimulation and other causes is irreversible and leads to permanent sensorineural hearing loss. To restore hearing, it is necessary to generate new functional hair cells. One potential way to regenerate hair cells is to induce a phenotypic transdifferentiation of nonsensory cells that remain in the deaf cochlea. Here we report that Atoh1, a gene also known as Math1 encoding a basic helix-loop-helix transcription factor and key regulator of hair cell development, induces regeneration of hair cells and substantially improves hearing thresholds in the mature deaf inner ear after delivery to nonsensory cells through adenovectors. This is the first demonstration of cellular and functional repair in the organ of Corti of a mature deaf mammal. The data suggest a new therapeutic approach based on expressing crucial developmental genes for cellular and functional restoration in the damaged auditory epithelium and other sensory systems.
