RESUMEN

BACKGROUND: Strategies are needed to better address the physical health needs of people with serious mental illness (SMI). Enhanced primary care for people with SMI has the potential to improve care of people with SMI, but evidence is lacking. OBJECTIVE: To examine the effect of a novel enhanced primary care model for people with SMI on service use and screening. DESIGN: Using North Carolina Medicaid claims data, we performed a retrospective cohort analysis comparing healthcare use and screening receipt of people with SMI newly receiving enhanced primary care to people with SMI newly receiving usual primary care. We used inverse probability of treatment weighting to estimate average differences in outcomes between the treatment and comparison groups adjusting for observed baseline characteristics. PARTICIPANTS: People with SMI newly receiving primary care in North Carolina. INTERVENTIONS: Enhanced primary care that includes features tailored for individuals with SMI. MAIN MEASURES: Outcome measures included outpatient visits, emergency department (ED) visits, inpatient stays and days, and recommended screenings 18 months after the initial primary care visit. KEY RESULTS: Compared to usual primary care, enhanced primary care was associated with an increase of 1.2 primary care visits (95% confidence interval [CI]: 0.31 to 2.1) in the 18 months after the initial visit and decreases of 0.33 non-psychiatric inpatient stays (CI: - 0.49 to - 0.16) and 3.0 non-psychiatric inpatient days (CI: - 5.3 to - 0.60). Enhanced primary care had no significant effect on psychiatric service and ED use. Enhanced primary care increased the probability of glucose and HIV screening, decreased the probability of lipid screening, and had no effect on hemoglobin A1c and colorectal cancer screening. CONCLUSIONS: Enhanced primary care for people with SMI can increase receipt of some preventive screening and decrease use of non-psychiatric inpatient care compared to usual primary care.

RESUMEN

Issue: Despite clear relevance, need, descriptive literature, and student interest, few schools offer required curriculum to develop leadership skills. This paper outlines a proposed shared vision for leadership development drawn from a coalition of diverse medical schools. We advocate that leadership development is about self (looking inward), teams (not hierarchy), and change (looking outward). We propose that leadership development is for all medical students, not for a subset, and we believe that leadership curricula and programs must be experiential and applied. Evidence: This paper also draws on the current literature and the experience of medical schools participating in the American Medical Association's (AMA) Accelerating Change in Medical Education Consortium, confronts the common arguments against leadership training in medical education, and provides three cross-cutting principles that we believe must each be incorporated in all medical student-centered leadership development programs as they emerge and evolve at medical schools. Implications: By confronting common arguments against leadership training and providing a framework for such training, we give medical educators important tools and insights into developing leadership training for all students at their institutions.

RESUMEN

Patients with Serious Mental Illness (SMI) have high rates of emergency department visits and high premature mortality rates, often due to poor primary care. A model of enhanced primary care services integrated in a behavioral health location is being implemented and studied at the UNC WakeBrook Primary Care Center (UNCWPC). This research was conducted as a retrospective cohort study. ED Visit Utilization before and after establishing care at UNCWPC were calculated for a cohort and a subset of patients. There was a decrease in ED utilization after years 3-4 of enrollment for physical health complaints for the overall cohort (n = 101), from 3.23 to 1.83 visits/person/year, and for patients with multiple physical comorbidities (n = 50), from 4.04 to 2.48 visits/person/year. This study indicated that an enhanced model of primary care can help decrease ED utilization for primary care conditions. The decline was not seen until the patients were well-established.

RESUMEN

Despite pronounced disparities in mortality and physical health outcomes, no well accepted models exist for integrating primary care with behavioral health for patients with serious mental illness (SMI). This article describes a case study of an enhanced approach to primary care that builds on the patient centered medical home (PCMH) model and adds three additional components: (1) longer and more frequent visits to establish trust and increase adherence, (2) a primary care team that has both the skills to provide effective primary care and the heart to take care of patients with SMI and (3) planned and proactive communication between the behavioral health team and the primary care team.

RESUMEN

Problem: A large state university in the southeastern United States and state Area Health Education Centers (AHEC) collaborated to establish branch campuses to increase clinical capacity for medical student education. Prior to formally becoming branch campuses, two AHEC sites had established innovative curricular structures different than the central campus. These sites worked with the central campus as clinical training sites. Upon becoming formal campuses, their unique clinical experiences were maintained. A third campus established a curricular structure identical to the central campus. Little exists in the literature regarding strategies that ensure comparability yet allow campuses to remain unique and innovative. Intervention: We implemented a balanced matrix organizational structure, well-defined communication plan, and newly developed tool to track comparability. A balanced matrix organization model framed the campus relationships. Adopting this model led to identifying reporting structures, developing multidirectional communication strategies, and the Campus Comparability Tool. Context: The UNC School of Medicine central campus is in Chapel Hill. All 192 students complete basic science course work on central campus. For required clinical rotations, approximately 140 students are assigned to the central campus, which includes rotations in Raleigh or Greensboro. The remaining students are assigned to Asheville (25-30), Charlotte (25-30), or Wilmington (5-7). Chapel Hill and Wilmington follow identical rotation structures, 16 weeks each of (a) combined surgery and adult inpatient experiences; (b) combined obstetrics/gynecology, psychiatry, and inpatient pediatrics; and (c) longitudinal clinical experiences in adult and pediatric medicine. Asheville offers an 8-month longitudinal integrated outpatient experience with discreet inpatient experiences in surgery and adult care. Charlotte offers a 6-month longitudinal integrated experiences and 6 months of block inpatient experiences. Aside from Charlotte and Raleigh, the other sites are urban but surrounded by rural counties. Chapel Hill is 221 miles from Asheville, 141 from Charlotte, and 156 from Wilmington. Outcome: Using the balanced matrix organization, various reporting structures and lines of communication ensured the educational objectives for students were clear on all campuses. The communication strategies facilitated developing consistent evaluation metrics across sites to compare educational experiences. Lessons Learned: The complexities of different healthcare systems becoming regional campuses require deliberate planning and understanding the culture of those sites. Recognizing how size and location of the organization affects communication, the central campus took the lead centralizing functions when appropriate. Adopting uniform educational technology has played an essential role in evaluating the comparability of core educational content on campuses delivering content in very distinct ways.

RESUMEN

S1P1 (sphingosine-1-phosphate receptor 1) agonists prevent lymphocyte egress from secondary lymphoid organs and cause a reduction in the number of circulating blood lymphocytes. We hypothesized that S1P1 receptor modulators with pathway-selective signaling properties could help to further elucidate the molecular mechanisms involved in lymphocyte trapping. A proprietary S1P1 receptor modulator library was screened for compounds with clear potency differences in ß-arrestin recruitment and G protein alpha i subunit (G αi) protein-mediated signaling. We describe here the structure-activity relationships of highly potent S1P1 modulators with apparent pathway selectivity for ß-arrestin recruitment. The most differentiated compound, D3-2, displayed a 180-fold higher potency in the ß-arrestin recruitment assay (EC50 0.9 nM) compared with the G αi-activation assay (167 nM), whereas ponesimod, a S1P1 modulator that is currently in advanced clinical development in multiple sclerosis, was equipotent in both assays (EC50 1.5 and 1.1 nM, respectively). Using these novel compounds as pharmacological tools, we showed that although a high potency in ß-arrestin recruitment is required to fully internalize S1P1 receptors, the potency in inducing G αi signaling determines the rate of receptor internalization in vitro. In contrast to ponesimod, the compound D3-2 did not reduce the number or circulating lymphocytes in rats despite high plasma exposures. Thus, for rapid and maximal S1P1 receptor internalization a high potency in both G αi signaling and ß-arrestin recruitment is mandatory and this translates into efficient reduction of the number of circulating lymphocytes in vivo.

RESUMEN

OBJECTIVE: Emergency Departments (ED) are overburdened with patients experiencing acute mental health crises. Pre-hospital transport by Emergency Medical Services (EMS) to community mental health and substance abuse treatment facilities could reduce ED utilization and costs. Our objective was to describe characteristics, treatment, and outcomes of acute mental health crises patients who were transported by EMS to an acute crisis unit at WakeBrook, a North Carolina community mental health center. METHODS: We performed a retrospective cohort study of patients diverted to WakeBrook by EMS from August 2013-July 2014. We abstracted data from WakeBrook medical records and used descriptive statistics to quantify patient characteristics, diagnoses, length of stay (LOS), and 30-day recidivism. RESULTS: A total of 226 EMS patients were triaged at WakeBrook. The median age was 38 years, 55% were male, 58% were white, and 38% were uninsured. The most common chief complaints were suicidal ideation or self-harm (46%) and substance abuse (19%). The most common diagnoses were substance-related and addictive disorders (42%), depressive disorders (32%), and schizophrenia spectrum and other psychotic disorders (22%). Following initial evaluation, 28% of patients were admitted to facilities within WakeBrook, 40% were admitted to external psychiatric facilities, 18% were stabilized and discharged home, 5% were transferred to an ED within 4 hours for further medical evaluation, and 5% refused services. The median LOS at WakeBrook prior to disposition was 12.0 hours (IQR 5.4-21.6). Over a 30-day follow-up period, 60 patients (27%) had a return visit to the ED or WakeBrook for a mental health issue. CONCLUSIONS: A dedicated community mental health center is able to treat patients experiencing acute mental health crises. LOS times were significantly shorter compared to regional EDs. Successful broader programmatic implementation could improve care quality and significantly reduce the volume of patients treated in the ED for acute mental health disorders.

RESUMEN

Life expectancy and other outcomes for patients with serious mental illness (SMI) are unacceptably poor, largely due to a high prevalence of poorly controlled chronic diseases, high rates of tobacco use, and low rates of preventive care services. Since many of these illnesses are effectively treated in primary care settings, integrating primary care with behavioral health care is necessary to narrow health disparities for patients with SMI.

RESUMEN

ISSUE: Community-based instruction is invaluable to medical students, as it provides "real-world" opportunities for observing and following patients over time while refining history taking, physical examination, differential diagnosis, and patient management skills. Community-based ambulatory settings can be more conducive to practicing these skills than highly specialized, academically based practice sites. The Association of American Medical Colleges and other national medical education organizations have expressed concern about recruitment and retention of preceptors to provide high-quality educational experiences in community-based practice sites. These concerns stem from constraints imposed by documentation in electronic health records; perceptions that student mentoring is burdensome resulting in decreased clinical productivity; and competition between allopathic, osteopathic, and international medical schools for finite resources for medical student experiences. EVIDENCE: In this Alliance for Clinical Education position statement, we provide a consensus summary of representatives from national medical education organizations in 8 specialties that offer clinical clerkships. We describe the current challenges in providing medical students with adequate community-based instruction and propose potential solutions. IMPLICATIONS: Our recommendations are designed to assist clerkship directors and medical school leaders overcome current challenges and ensure high-quality, community-based clinical learning opportunities for all students. They include suggesting ways to orient community clinic sites for students, explaining how students can add value to the preceptor's practice, focusing on educator skills development, recognizing preceptors who excel in their role as educators, and suggesting forms of compensation.

RESUMEN

Synthetic sphingosine 1-phosphate receptor 1 modulators constitute a new class of drugs for the treatment of autoimmune diseases. Sphingosine 1-phosphate (S1P) signaling, however, is also involved in the development of fibrosis. Using normal human lung fibroblasts, we investigated the induction of fibrotic responses by the S1P receptor (S1PR) agonists S1P, FTY720-P, ponesimod, and SEW2871 and compared them with the responses induced by the known fibrotic mediator TGF-ß1. In contrast to TGF-ß1, S1PR agonists did not induce expression of the myofibroblast marker α-smooth muscle actin. However, TGF-ß1, S1P, and FTY720-P caused robust stimulation of extracellular matrix (ECM) synthesis and increased pro-fibrotic marker gene expression including connective tissue growth factor. Ponesimod showed limited and SEW2871 showed no pro-fibrotic potential in these readouts. Analysis of pro-fibrotic signaling pathways showed that in contrast to TGF-ß1, S1PR agonists did not activate Smad2/3 signaling but rather activated PI3K/Akt and ERK1/2 signaling to induce ECM synthesis. The strong induction of ECM synthesis by the nonselective agonists S1P and FTY720-P was due to the stimulation of S1P2 and S1P3 receptors, whereas the weaker induction of ECM synthesis at high concentrations of ponesimod was due to a low potency activation of S1P3 receptors. Finally, in normal human lung fibroblast-derived myofibroblasts that were generated by TGF-ß1 pretreatment, S1P and FTY720-P were effective stimulators of ECM synthesis, whereas ponesimod was inactive, because of the down-regulation of S1P3R expression in myofibroblasts. These data demonstrate that S1PR agonists are pro-fibrotic via S1P2R and S1P3R stimulation using Smad-independent pathways.

RESUMEN

Primary care organizations must transform care delivery to realize the Institute for Healthcare Improvement's Triple Aim of better healthcare, better health, and lower healthcare costs. However, few studies have considered the financial implications for primary care practices engaged in transformation. In this qualitative, comparative case study, we examine the practice-level personnel and nonpersonnel costs and the benefits involved in transformational change among 12 primary care practices participating in North Carolina's Improving Performance in Practice (IPIP) program. We found average annual opportunity costs of $21,550 ($6,659 per full-time equivalent provider) for maintaining core IPIP activities (e.g., data management, form development and maintenance, meeting attendance). This average represents the cost of a 50% full-time equivalent registered nurse or licensed practical nurse. Practices were able to limit transformation costs by scheduling meetings during relatively slow patient care periods and by leveraging resources such as the assistance of IPIP practice coaches. Still, the costs of practice transformation were not trivial and would have been much higher in the absence of these efforts. Benefits of transformation included opportunities for enhanced revenue through reimbursement incentives and practice growth, improved efficiency and care quality, and maintenance of certification. Given the potentially high costs for some practices, policy makers may need to consider reimbursement and other strategies to help primary care practices manage the costs of practice redesign.

RESUMEN

Objective: People with serious mental illness (SMI) have high rates of cardiometabolic illness, receive low quality care, and experience poor outcomes. Nevertheless, studies of existing integrated care models have not consistently shown improvements in cardiometabolic health for people with SMI. This study assessed the effect of a novel model of enhanced primary care for people with SMI on cardiometabolic outcomes. Enhanced primary care is a model of integrated care wherein comprehensive primary care delivery is adapted to the needs of people with SMI in coordination with behavioral care.Methods: We conducted a propensity-weighted cohort study comparing 234 patients with SMI receiving enhanced primary care to 4,934 patients with SMI receiving usual primary care using electronic health data from a large academic medical system covering the years 2014-2018. The propensity-weighted models controlled for baseline differences in outcome measures and patient characteristics between groups.Results: Compared to usual primary care, enhanced primary care increased hemoglobin A1c (HbA1c) screening by 18 percentage points (95% confidence interval [CI], 10 to 25), low-density lipoprotein (LDL) screening by 16 percentage points (CI, 8.8 to 24), and blood pressure screening by 7.8 percentage points (CI, 5.8 to 9.9). Enhanced primary care reduced HbA1c by 0.27 percentage points (CI, -0.47 to -0.060) and systolic blood pressure by 3.9 mm Hg (CI, -5.2 to -2.5) compared to usual primary care. We did not find evidence that enhanced primary care consistently affected glucose screening, LDL values, or diastolic blood pressure.Conclusions: Enhanced primary care can achieve clinically meaningful improvements in cardiometabolic health compared to usual primary care.

RESUMEN

BACKGROUND: Medical records that do not accurately reflect the patient's current medication list are an open invitation to errors and may compromise patient safety. METHODS: This cross-sectional study compares primary care provider (PCP) medication lists and pharmacy claims for 100 patients seen in 8 primary care practices and examines the association of congruence with demographic, clinical, and practice characteristics. Medication list congruence was measured as agreement of pharmacy claims with the entire PCP chart, including current medication list, visit notes, and correspondence sections. RESULTS: Congruence between pharmacy claims and the PCP chart was 65%. Congruence was associated with large chronic disease burden, frequent PCP visits, group practice, and patient age ≥45 years. CONCLUSION: Agreement of medication lists between the PCP chart and pharmacy records is low. Medication documentation was more accurate among patients who have more chronic conditions, those who have frequent PCP visits, those whose practice has multiple providers, and those at least 45 years of age. Improved congruence among patients with multiple chronic conditions and in group practices may reflect more frequent visits and reviews by providers.

RESUMEN

BACKGROUND: For years, US medical schools have relied on community-based, private clinicians to educate medical students. There has been a steady decline in the number of physicians willing to take on medical students in their clinical practices. Recent issues related to the pandemic raise questions about how many patients students should see to have a meaningful clinical experience. METHODS: As part of a 16-week longitudinal clinical experience, medical students spend 2 days each week in a family medicine or internal medicine clinic. As repetition enhances learning, maximizing the number of patients students see is important. Using a mixed integer linear program, we sought to determine the optimal schedule that maximizes the number of patients whom students see during a rotation. Patient visits were collected from January to April 2018 for clinics used by the medical school. By maximizing the minimum number of patients per learner over all non-empty day-clinic combinations, we deliver equitable rotation plans based on our assumptions. RESULTS: For this pilot study, multiple experiments were performed with different numbers of students assigned to clinics. Each experiment also generated a weekly rotation plan for a given student. Based on this optimization model, the minimum number of patients per student over 16 weeks was 87 (3 patients per day) and actually increased the number of students who could be assigned to one of the clinics from 1 student per rotation to 8 students. CONCLUSIONS: The mixed integer linear program assigned more students to clinics that have more total visits in order to achieve the optimal and fairest learning quality. In addition, by conducting various experiments on different numbers of students, we observed that we were able to allocate more students without affecting the number of patients students see.

RESUMEN

Lymphocyte exit from lymph nodes and their recirculation into blood is controlled by the sphingolipid sphingosine 1-phosphate (S1P). The cellular receptor mediating lymphocyte exit is S1P(1), one of five S1P receptors. Nonselective agonists for S1P receptors lead to blood lymphocyte count reduction. The effects of selective S1P(1) agonists on blood lymphocyte count and their impact in models of lymphocyte-mediated tissue inflammation have been less investigated. We describe here the general pharmacology of ponesimod, (Z,Z)-5-[3-chloro-4-((2R)-2,3-dihydroxy-propoxy)-benzylidene]-2-propylimino-3-o-tolyl-thiazolidin-4-one, a new, potent, and orally active selective S1P(1) agonist. Ponesimod activated S1P(1)-mediated signal transduction with high potency (EC(50) of 5.7 nM) and selectivity. Oral administration of ponesimod to rats led to a dose-dependent decrease of blood lymphocyte count. After discontinuation of dosing, blood lymphocyte count returned to baseline within 48 h. Ponesimod prevented edema formation, inflammatory cell accumulation, and cytokine release in the skin of mice with delayed-type hypersensitivity. Ponesimod also prevented the increase in paw volume and joint inflammation in rats with adjuvant-induced arthritis. These data show that selective activation of S1P(1) using ponesimod leads to blood lymphocyte count reduction and efficacy in models of lymphocyte-mediated tissue inflammation. Immunomodulation with a rapidly reversible S1P(1)-selective agonist may represent a new therapeutic approach in lymphocyte-mediated autoimmune diseases.

RESUMEN

Background To say that the transition from undergraduate medical education (UME) to graduate medical education (GME) is under scrutiny would be an understatement. Findings from a panel discussion at the 2018 Association of American Medical Colleges Annual meeting entitled, "Pass-Fail in Medical School and the Residency Application Process and Graduate Medical Education Transition" addressed what and when information should be shared with residency programs, and how and when that information should be shared. Materials and Methods Over 250 participants representing UME and GME (e.g. leadership, faculty, medical students) completed worksheets addressing these questions. During report-back times, verbal comments were transcribed in real time, and written comments on worksheets were later transcribed. All comments were anonymous. Thematic analysis was conducted manually by the research team to analyze the worksheet responses and report back comments. Results Themes based on suggestions of what information should be shared included the following: 1) developmental/assessment benchmarks such as demonstrating the ability/competencies to do clinical work; 2) performance on examinations; 3) grades and class ranking; 4) 360 evaluations; 5) narrative evaluations; 6) failures/remediation/gaps in training; 7) professionalism lapses; 8) characteristics of students such as resiliency/reliability; and 9) service/leadership/participation. In terms of how this information should be shared, the participants suggested enhancements to the current process of transmitting documents rather than alternative methods (e.g., video, telephonic, face-to-face discussions) and information sharing at both the time of the match and again near/at graduation to include information about post-match rotations. Discussion Considerations to address concerns with the transition from medical school to residency include further enhancements to the Medical Student Performance Evaluation, viewing departmental letters as ones of evaluation and not recommendation, a more meaningful educational handoff, and limits on the number of residency applications allowed for each student. The current medical education environment is ready for meaningful change in the UME to GME transition.

Background Over the past 40 years, the physician supply of North Carolina (NC) grew faster than the total population. However, the distribution of physicians between urban and rural areas increased, with many more physicians in urban areas. In rural counties, access to care and health disparities remain concerning. As a result, the medical school implemented pipeline programs to recruit more rural students. This study investigates the results of these recruitment efforts. Methodology Descriptive analyses were conducted to compare the number and percentage of rural and urban students from NC who applied, interviewed, and were accepted to the University of North Carolina's School of Medicine (UNC SOM). The likely pool of rural applicants was based on the number of college-educated 18-34-year-olds by county. Results Roughly 10.9% of NC's population of college-educated 18-34-year-olds live in rural counties. Between 2017 and 2019, 9.3% (n = 225) of UNC SOM applicants were from a rural county. An increase of just 14 additional rural applicants annually would bring the proportion of rural UNC SOM applicants in alignment with the potential applicant pool in rural NC counties. Conclusions Our model of analysis successfully calculated the impact of recruitment efforts to achieve proportional parity in the medical school class with the rural population of the state. Addressing rural physician workforce needs will require multiple strategies that affect different parts of the medical education and healthcare systems, including boosting college completion rates in rural areas. This model of analysis can also be applied to other pipeline programs to document the success of the recruitment efforts.
