Implementation of a Multidisciplinary Team to Improve the Quality of Care for Older Surgical Patients at a Rural Academic Medical Center.

For the first time in history, people age older than 65 years make up >20% of the non-metro population, compared with 16% of the metro population. From 2010 to 2020 the nonmetro population age older than 65 years grew by 22%, while the working-age population declined by 4.9%, and the population aged under 18 years declined by 5.7%.1,2 Multidisciplinary geriatric surgical programs are an increasingly recognized approach to the care of older surgical patients and preliminary data suggest they can reduce length of stay. Although rural areas have the greatest proportion of patients age older than 65 years, implementation of such programs faces special challenges in rural settings with limited resources. Dartmouth-Hitchcock Medical Center is one of the most rural academic centers in the United States. Challenges include a shortage of geriatric-trained providers, long distances to access primary care and subspecialists, and extremely limited postacute care options and skilled nursing facility beds. To address the unique needs of our provider and patient population we began with a development period where we conducted stakeholder interviews. Using these data, we mapped out a workflow and developed pilot projects to address different portions of the workflow, such as preoperative screening for frailty and cognitive impairment, interdisciplinary weekly case conferences, proactive case management, delirium and geriatric surgery postoperative pathway order sets, and a variety of tools for reorientation and delirium management. Herein we describe the process of development and pragmatic clinical implementation of geriatric-focused care for older surgical patients in our rural tertiary center, including some of the main challenges we faced and the strategies we undertook to overcome them, and some of our early patient centered and clinical outcomes. This information may assist other institutions as they design geriatric-focused surgical programs to address the growing population of older adults and the need for compliance with state legislation. The clinical program described is not a research study, and the outcome data we report is for the purpose of description, and should not be interpreted as a rigorous research investigation of the effect of our intervention.

Using Academic Consultation-Liaison Telepsychiatry to Meet the Mental Health Needs of Complex, Medically Ill Patients in Underserved Areas: A Case Report.

Background: The nationwide shortage of mental health resources often disproportionately affects rural areas. As innovative strategies are required to address mental health resource shortages in rural areas, telepsychiatry consultation (TPC) may represent a population health-oriented approach to bridge this gap. In this case report, we examine the use of TPC from an academic consultation-liaison psychiatry service to a rural community hospital. Case Report: We describe the case of a woman with Wernicke encephalopathy seeking to leave the hospital against medical advice and the role that the TPC service played in the patient's evaluation and management, including assessing decision-making capacity. Discussion: We then examine benefits and limitations of the service, including a narrative review of the relevant, but limited, available literature as well as suggestions for how the service may be improved and incorporated into psychiatry residency and fellowship training in the future.

Improving care for individuals with serious infections who inject drugs.

Background: Hospitalizations for serious infections requiring long-term intravenous (IV) antimicrobials related to injection drug use have risen sharply over the last decade. At our rural tertiary care center, opportunities for treatment of underlying substance use disorders were often missed during these hospital admissions. Once medically stable, home IV antimicrobial therapy has not traditionally been offered to this patient population due to theoretical concerns about misuse of long-term IV catheters, leading to discharges with suboptimal treatment regimens, lengthy hospital stays, or care that is incongruent with patient goals and preferences. Methods: A multidisciplinary group of clinicians and patients set out to redesign and improve care for this patient population through a health care innovation process, with a focus on increasing the proportion of patients who may be discharged on home IV therapy. Baseline assessment of current experience was established through retrospective chart review and extensive stakeholder analysis. The innovation process was based in design thinking and facilitated by a health care delivery improvement incubator. Results: The components of the resulting intervention included early identification of hospitalized people who inject drugs with serious infections, a proactive psychiatry consultation service for addiction management for all patients, a multidisciplinary care conference to support decision making around treatment options for infection and substance use, and care coordination/navigation in the outpatient setting with a substance use peer recovery coach and infectious disease nurse for patients discharged on home IV antimicrobials. Patients discharged on home IV therapy followed routine outpatient parenteral antimicrobial therapy (OPAT) protocols and treatment protocols for addiction with their chosen provider. Conclusion: An intervention developed through a design-thinking-based health care redesign process improved patient-centered care for people with serious infections who inject drugs.

Search for Event Rate Modulation in XENON100 Electronic Recoil Data.

We have searched for periodic variations of the electronic recoil event rate in the (2-6) keV energy range recorded between February 2011 and March 2012 with the XENON100 detector, adding up to 224.6 live days in total. Following a detailed study to establish the stability of the detector and its background contributions during this run, we performed an unbinned profile likelihood analysis to identify any periodicity up to 500 days. We find a global significance of less than 1σ for all periods, suggesting no statistically significant modulation in the data. While the local significance for an annual modulation is 2.8σ, the analysis of a multiple-scatter control sample and the phase of the modulation disfavor a dark matter interpretation. The DAMA/LIBRA annual modulation interpreted as a dark matter signature with axial-vector coupling of weakly interacting massive particles to electrons is excluded at 4.8σ.

Limits on spin-dependent WIMP-nucleon cross sections from 225 live days of XENON100 data.

We present new experimental constraints on the elastic, spin-dependent WIMP-nucleon cross section using recent data from the XENON100 experiment, operated in the Laboratori Nazionali del Gran Sasso in Italy. An analysis of 224.6 live days×34 kg of exposure acquired during 2011 and 2012 revealed no excess signal due to axial-vector WIMP interactions with 129Xe and 131Xe nuclei. This leads to the most stringent upper limits on WIMP-neutron cross sections for WIMP masses above 6 GeV/c², with a minimum cross section of 3.5×10(-40) cm² at a WIMP mass of 45 GeV/c², at 90% confidence level.

Dark matter results from 225 live days of XENON100 data.

We report on a search for particle dark matter with the XENON100 experiment, operated at the Laboratori Nazionali del Gran Sasso for 13 months during 2011 and 2012. XENON100 features an ultralow electromagnetic background of (5.3 ± 0.6) × 10(-3) events/(keV(ee) × kg × day) in the energy region of interest. A blind analysis of 224.6 live days × 34 kg exposure has yielded no evidence for dark matter interactions. The two candidate events observed in the predefined nuclear recoil energy range of 6.6-30.5 keV(nr) are consistent with the background expectation of (1.0 ± 0.2) events. A profile likelihood analysis using a 6.6-43.3 keV(nr) energy range sets the most stringent limit on the spin-independent elastic weakly interacting massive particle-nucleon scattering cross section for weakly interacting massive particle masses above 8 GeV/c(2), with a minimum of 2 × 10(-45) cm(2) at 55 GeV/c(2) and 90% confidence level.
