RESUMO

Randomized controlled trials to improve care for complex, high-need, high-cost patients have not consistently demonstrated a relative decrease in acute care utilization or cost savings. However, the Veterans Health Administration (VHA) has been able to glean lessons from these trials and generate realistic expectations for success. Lessons include the following: (1) combining population management tools (e.g., risk scores) and clinician judgment is more effective than either alone to identify the patients best suited for intensive management; (2) treatment adherence and engagement may contribute more to preventable emergency department visits and hospitalizations than care coordination; and (3) efforts should focus on assessing for and treating those risk factors that are most amenable to intervention. Because it is unlikely that cost savings can fund add-on intensive management programs, the VHA Office of Primary Care plans to incorporate those intensive management practices that are feasible into existing patient-centered medical homes as a high reliability organization.

RESUMO

BACKGROUND: Intensive primary care programs have had variable impacts on clinical outcomes, possibly due to a lack of consensus on appropriate patient-selection. The US Veterans Health Administration (VHA) piloted an intensive primary care program, known as Patient Aligned Care Team Intensive Management (PIM), in five medical centers. We sought to describe the PIM patient selection process used by PIM teams and to explore perspectives of PIM team members regarding how patient selection processes functioned in context. METHODS: This study employs an exploratory sequential mixed-methods design. We analyzed qualitative interviews with 21 PIM team and facility leaders and electronic health record (EHR) data from 2,061 patients screened between July 2014 and September 2017 for PIM enrollment. Qualitative data were analyzed using a hybrid inductive/deductive approach. Quantitative data were analyzed using descriptive statistics. RESULTS: Of 1,887 patients identified for PIM services using standardized criteria, over half were deemed inappropriate for PIM services, either because of not having an ambulatory care sensitive condition, living situation, or were already receiving recommended care. Qualitative analysis found that team members considered standardized criteria to be a useful starting point but too broad to be relied on exclusively. Additional data collection through chart review and communication with the current primary care team was needed to adequately assess patient complexity. Qualitative analysis further found that differences in conceptualizing program goals led to conflicting opinions of which patients should be enrolled in PIM. CONCLUSIONS: A combined approach that includes clinical judgment, case review, standardized criteria, and targeted program goals are all needed to support appropriate patient selection processes.

RESUMO

ABSTRACT: Interprofessional collaboration (IPC) has been shown to improve healthcare quality and patient safety; however, formal interprofessional education (IPE) training is insufficient. The VA Quality Scholars (VAQS) program exists to develop interprofessional leaders and scholars in healthcare improvement. The purpose of this study was to examine the impact of integrating interprofessional healthcare learners and designing an interprofessional curriculum for the national VAQS program. VAQS alumni (graduates from 2001 to 2017) across eight national sites (n = 102 [53.1%]) completed a web-based survey to assess alumni perceptions of IPC skill development during the program and IPC skill utilization in their careers. Alumni from 2009 and earlier were physicians; alumni after 2009 came from diverse health professional backgrounds. Overall, IPC and teamwork was identified as the most used skill (n = 82, 70%) during their career. When comparing the pre-IPE period and the post-IPE period, post-IPE alumni identified IPC and teamwork as the area of greatest skill development (n = 38). Integrating interprofessional trainees and robust IPE curricula enhanced an established and successful quality improvement (QI) training program. VAQS alumni endorsed the importance of IPC skills during their careers. The VAQS program is an example of how health professionals can successfully learn IPC skills in healthcare QI.

RESUMO

Bereavement is associated with an increased risk of psychiatric morbidity and all-cause mortality, particularly in younger people and after unnatural deaths. Substance misuse is implicated but little research has investigated patterns of drug or alcohol use after bereavement. We used a national online survey to collect qualitative data describing whether and how substance use changes after sudden bereavement. We conducted thematic analysis of free-text responses to a question probing use of alcohol and drugs after the sudden unnatural (non-suicide) death of a family member or a close friend. We analysed data from 243 adults in British Higher Education Institutions aged 18-40, identifying two main themes describing post-bereavement alcohol or drug use: (1) sense of control over use of drugs or alcohol (loss of control versus self-discipline), (2) harnessing the specific effects of drugs or alcohol. Across themes we identified age patterning in relation to substance misuse as a form of rebellion among those bereaved in childhood, and gender patterning in relation to men using alcohol to help express their emotions. The limitations of our sampling mean that these findings may not be generalizable from highly-educated settings to young people in the general population. Our findings describe how some young bereaved adults use drugs and alcohol to help them cope with traumatic loss, and suggest how clinicians might respond to any difficulties controlling substance use.

RESUMO

Studies describing the impact of suicide bereavement report an excess risk of suicide, suicide attempt, psychiatric illness, and drug and alcohol use disorders compared with the general population. However, the nature of patterns of drug and alcohol use after suicide bereavement is unclear. We used an online survey to collect qualitative data to understand whether and how drug and alcohol use changes after suicide bereavement. We conducted thematic analysis of free-text responses to a question capturing their use of alcohol and drugs after the suicide of a family member or a close friend. Analysing data from 346 adults in Britain aged 18-40, we identified three main themes describing the relationship of suicide bereavement to alcohol or drug use: (1) control over drug or alcohol use, (2) the perceived purpose of using drugs or alcohol, and (3) the attribution of drug or alcohol misuse to external factors. Overlying these themes were dimensions of control and of awareness of potential harms. This study highlights that increased use of drugs and alcohol after suicide bereavement may form part of a bereaved person's coping strategies, and that sensitive approaches are needed when judging whether and when to intervene.

RESUMO

Many integrated health systems and accountable care organizations have turned to intensive primary care programs to improve quality of care and reduce costs for high-need high-cost patients. How best to implement such programs remains an active area of discussion. In 2014, the Veterans Health Administration (VHA) implemented five distinct intensive primary care programs as part of a demonstration project that targeted Veterans at the highest risk for hospitalization. We found that programs evolved over time, eventually converging on the implementation of the following elements: 1) an interdisciplinary care team, 2) chronic disease management, 3) comprehensive patient assessment and evaluation, 4) care and case management, 5) transitional care support, 6) preventive home visits, 7) pharmaceutical services, 8) chronic disease self-management, 9) caregiver support services, 10) health coaching, and 11) advanced care planning. The teams also found that including social workers and mental health providers on the interdisciplinary teams was critical to effectively address psychosocial needs of these complex patients. Having a central implementation coordinator facilitated the convergence of these program features across diverse demonstration sites. In future iterations of these programs, VHA intends to standardize staffing and key features to develop a scalable program that can be disseminated throughout the system.

RESUMO

Mice with a single copy of the retinoblastoma gene (Rb(+/-)) develop a syndrome of multiple neuroendocrine neoplasia. They usually succumb to fast-growing, Rb-deficient melanotroph tumors of the pituitary intermediate lobe, which are extremely rare in humans. Thus, full assessment of Rb role in other, more relevant to human pathology, neoplasms is complicated. To prevent melanotroph neoplasia while preserving spontaneous carcinogenesis in other types of cells, we have prepared transgenic mice in which 770-bp fragment of pro-opiomelanocortin promoter directs expression of the human RB gene to melanotrophs (TgPOMC-RB). In three independent lines, transgenic mice crossed to Rb(+/-) background are devoid of melanotroph tumors but develop the usual spectrum of other neoplasms. Interestingly, abrogation of melanotroph carcinogenesis results in accelerated progression of pituitary anterior lobe tumors and medullary thyroid carcinomas. A combination of immunologic tests, cell culture studies, and tumorigenicity assays indicates that alpha-melanocyte-stimulating hormone, which is overproduced by melanotroph tumors, attenuates neoplastic progression by decreasing cell proliferation and inducing apoptosis. Taken together, we show that cell lineage-specific complementation of Rb function can be successfully used for refining available models of stochastic carcinogenesis and identify alpha-melanocyte-stimulating hormone as a potential attenuating factor during progression of neuroendocrine neoplasms.

RESUMO

Alterations in p53 and Rb pathways are observed frequently in epithelial ovarian cancer (EOC).However, their roles in EOC initiation remain uncertain. Using a single intrabursal administration of recombinant adenovirus expressing Cre, we demonstrate that concurrent inactivation of p53 and Rb1 is sufficient for reproducible induction of ovarian epithelial carcinogenesis in mice homozygous for conditional gene alleles. Similarly to progression of disease in women, ovarian neoplasms spread i.p., forming ascites, and metastasize to the contralateral ovary, the lung, and the liver. These results establish critical interactions between p53 and Rb1 pathways in EOC pathogenesis, and provide a genetically defined immunocompetent mouse model of sporadic EOC.

RESUMO

Reasons for resident underutilization of adverse event (AE) reporting systems are unclear, particularly given frequent resident exposure to AEs and near misses (NMs). Residents at an academic medical center were surveyed about AEs/NMs, barriers to reporting, patient safety climate, and educational interventions. A total of 350 of 527 eligible residents (66%) completed the survey; 77% of respondents reported involvement in an AE/NM, though only 43% had used the reporting system. Top barriers to reporting were not knowing what or how to report. Surgeons reported more than other residents (surgery, 61%; medical, 38%; hospital-based, 15%; P < .01), yet more often felt that systems were unlikely to change after reporting (surgery, 49%; medical, 28%; hospital-based. 18%; P < .01). Residents preferred discussions with supervisors (52%) and department-led conferences (46%) to increased reporting. Efforts to increase resident reporting should address common barriers to reporting as well as department-specific differences in resident knowledge, perceptions of system effectiveness, and educational preferences.

RESUMO

INTRODUCTION: The Geriatric Resources for the Assessment and Care of Elders (GRACE) program has been shown to decrease acute care utilization and increase patient self-rated health in low-income seniors at community-based health centers. AIMS: To describe adaptation of the GRACE model to include adults of all ages (named Care Support) and to evaluate the process and impact of Care Support implementation at an urban academic medical center. SETTING: 152 high-risk patients (≥5 ED visits or ≥2 hospitalizations in the past 12 months) enrolled from four medical clinics from 4/29/2013 to 5/31/2014. PROGRAM DESCRIPTION: Patients received a comprehensive in-home assessment by a nurse practitioner/social worker (NP/SW) team, who then met with a larger interdisciplinary team to develop an individualized care plan. In consultation with the primary care team, standardized care protocols were activated to address relevant key issues as needed. PROGRAM EVALUATION: A process evaluation based on the Consolidated Framework for Implementation Research identified key adaptations of the original model, which included streamlining of standardized protocols, augmenting mental health interventions and performing some assessments in the clinic. A summative evaluation found a significant decline in the median number of ED visits (5.5 to 0, p = 0.015) and hospitalizations (5.5 to 0, p<0.001) 6 months before enrollment in Care Support compared to 6 months after enrollment. In addition, the percent of patients reporting better self-rated health increased from 31% at enrollment to 64% at 9 months (p = 0.002). Semi-structured interviews with Care Support team members identified patients with multiple, complex conditions; little community support; and mild anxiety as those who appeared to benefit the most from the program. DISCUSSION: It was feasible to implement GRACE/Care Support at an academic medical center by making adaptations based on local needs. Care Support patients experienced significant reductions in acute care utilization and significant improvements in self-rated health.

RESUMO

OBJECTIVES: To determine life expectancy for older women with breast cancer. DESIGN: Prospective longitudinal study with 10 years of follow-up data. SETTING: Hospitals or collaborating tumor registries in four geographic regions (Los Angeles, California; Minnesota; North Carolina; Rhode Island). PARTICIPANTS: Women aged 65 and older at time of breast cancer diagnosis with Stage I to IIIA disease with measures of self-rated health (SRH) and walking ability at baseline (N = 615; 17% aged ≥80, 52% Stage I, 58% with ≥2 comorbidities). MEASUREMENTS: Baseline SRH, baseline self-reported walking ability, all-cause and breast cancer-specific estimated probability of 5- and 10-year survival. RESULTS: At the time of breast cancer diagnosis, 39% of women reported poor SRH, and 28% reported limited ability to walk several blocks. The all-cause survival curves appear to separate after approximately 3 years, and the difference in survival probability between those with low SRH and limited walking ability and those with high SRH and no walking ability limitation was significant (0.708 vs 0.855 at 5 years, P ≤ .001; 0.300 vs 0.648 at 10 years, P < .001). There were no differences between the groups in breast cancer-specific survival at 5 and 10 years (P = .66 at 5 years, P = .16 at 10 years). CONCLUSION: The combination of low SRH and limited ability to walk several blocks at diagnosis is an important predictor of worse all-cause survival at 5 and 10 years. These self-report measures easily assessed in clinical practice may be an effective strategy to improve treatment decision-making in older adults with cancer.

RESUMO

BACKGROUND AND PURPOSE: Small asymptomatic cerebral hemorrhages detectable by gradient-echo MRI are common in patients with intracerebral hemorrhage (ICH), particularly lobar ICH related to cerebral amyloid angiopathy (CAA). We sought to determine whether hemorrhages detected at the time of lobar ICH predict the major clinical complications of CAA: recurrent ICH or decline in cognition and function. METHODS: Ninety-four consecutive survivors of primary lobar ICH (age > or =55) with gradient-echo MRI at presentation were followed in a prospective cohort study for 32.9+/-24.0 months. A subset of 34 subjects underwent a second MRI after a stroke-free interval of 15.8+/-6.5 months. Study endpoints were recurrent symptomatic ICH or clinical decline, defined as onset of cognitive impairment, loss of independent functioning, or death. RESULTS: The total number of hemorrhages at baseline predicted risk of future symptomatic ICH (3-year cumulative risks 14%, 17%, 38%, and 51% for subjects with 1, 2, 3 to 5, or > or =6 baseline hemorrhages, P=0.003). Higher numbers of hemorrhages at baseline also predicted increased risk for subsequent cognitive impairment, loss of independence, or death (P=0.002) among subjects not previously demented or dependent. For subjects followed after a second MRI, new microhemorrhages appeared in 17 of 34 and predicted increased risk of subsequent symptomatic ICH (3-year cumulative risks 19%, 42%, and 67% for subjects with 0, 1 to 3, or > or =4 new microhemorrhages, P=0.02), but not subsequent clinical decline. CONCLUSIONS: Hemorrhages identified by MRI predict clinically important events in survivors of lobar ICH. Detection of microhemorrhages may be useful for assessing risk in ICH patients and as a surrogate marker for clinical studies.

RESUMO

A free-running diode laser has been used to examine the spectrum of 127I(2) near 675 nm using wavelength modulation spectroscopy. Twelve transitions have been observed in the region between 14818.0 and 14819.3 cm(-1), all of which are accounted for by previously published constants. Changes in quadrupole coupling constants, DeltaeQq, have been determined for all lines. Pressure broadening and shift coefficients have been determined for two unblended lines for broadening by air, argon, and water vapor.

RESUMO

To explore the clinical effects of inflammation associated with vascular deposits of the amyloid beta peptide (A beta), we analyzed 42 consecutive patients with pathologically diagnosed cerebral amyloid angiopathy (CAA) for evidence of an inflammatory response. Inflammation with giant-cell reaction surrounding amyloid-laden vessels was identified in 7 of the 42 cases. The clinical symptoms in each of the seven were subacute cognitive decline or seizure rather than hemorrhagic stroke, the primary clinical presentation in 33 of 35 patients with noninflammatory CAA (p < 0.001). Inflammatory CAA also was associated with radiographic white matter abnormalities, significantly younger age at presentation, and a marked overrepresentation of the apolipoprotein E epsilon 4/epsilon 4 genotype (71% vs 4%, p < 0.001). Of the six inflammatory CAA patients with available follow-up information, five demonstrated clinical and radiographic improvement after immunosuppressive treatment. The syndrome of CAA-related perivascular inflammation appears to represent a subset of CAA with clinically distinct symptoms that may respond to immunosuppressive treatment. These data add to evidence that inflammation against A beta can cause vascular dysfunction, a potential mechanism for the toxic response recently observed in clinical trials of A beta immunization.
