Single Source of Error State Space Approach to the Beveridge Nelson Decomposition
A well known property of the Beveridge Nelson decomposition is that the innovations in the permanent and transitory components are perfectly correlated. We use a single source of error state space model to exploit this property and perform a Beveridge Nelson decomposition. The single source of error state space approach to the decomposition is computationally simple, and in contrast to other methods of performing the Beveridge-Nelson decomposition, it incorporates the direct estimation of the long-run multiplier.Beveridge Nelson decomposition; Long-run multiplier; Single source of error; State-space models.
Characterization of Actions Taken During the Delivery of Medication Therapy Management: A Time-and-Motion Approach
OBJECTIVES:
To characterize actions performed by pharmacists and support staff during provision of medication therapy management (MTM) and to compare actions performed according to practice characteristics.
METHODS:
A purposeful sample of 7 MTM practices (2 call centers and 5 community practices) was identified and visited by investigators. Pharmacists and support staff were observed during their routine provision of MTM. Investigators characterized "major" (e.g., preparation for a comprehensive medication review) and "minor" (i.e., specific steps in overarching major action) actions with the use of a time-and-motion approach.
RESULTS:
A total of 32 major and 469 minor actions were observed. Practices were characterized as Later Maturity Level or Early Maturity Level on the basis of their self-reported MTM appointment volume, self-assessment of the extent of integration of chronic care model principles, and payer mix. Later Maturity Level practices were more likely to deliver follow-up medication therapy reviews and comprehensive medication reviews (CMRs) as opposed to targeted medication reviews (TMRs) and to receive physician referrals for MTM. Later Maturity Level practices were also more likely to use paid interns than pharmacy rotation students. CMR activities observed at Later Maturity Level practices lasted a median of 30.8 minutes versus 20.3 minutes for CMR activities at Early Maturity Level practices. Similarly, TMR activities observed at Later Maturity Level practices were longer: a median of 31.0 minutes versus 12.3 minutes. At Later Maturity Level practices, pharmacists spent a greater proportion of time providing patient education, while support staff spent a greater proportion of time on tasks such as capturing demographics and introducing or explaining MTM.
CONCLUSION:
MTM activities were longer at Later Maturity Level practices, and these practices were more likely to use paid pharmacy interns and to receive physician referrals for MTM. This work provides a foundation for future research
Factors associated with comprehensive medication review completion rates: A national survey of community pharmacists
Background
Completion rates for medication therapy management (MTM) services have been lower than desired and the Centers for Medicare and Medicaid Services has added MTM comprehensive medication review (CMR) completion rates as a Part D plan star measure. Over half of plans utilize community pharmacists via contracts with MTM vendors.
Objectives
The primary objective of this survey study was to identify factors associated with the CMR completion rates of community pharmacies contracted with a national MTM vendor.
Methodsl
Representatives from 27,560 pharmacy locations contracted with a national MTM vendor were surveyed. The dependent variable of interest was the pharmacies' CMR completion rate. Independent variables included the pharmacy's progressiveness stratum and number of CMRs assigned by the MTM vendor during the time period, as well as self-reported data to characterize MTM facilitators, barriers, delivery strategies, staffing, selected items from a modified Assessment of Chronic Illness Care, and pharmacist/pharmacy demographics. Univariate negative binomial models were fit for each independent variable, and variables significant at p < 0.05 were entered into a multivariable model.
Results
Representatives from 3836 (13.9%) pharmacy locations responded; of these, 90.9% (n = 3486) responses were useable. The median CMR completion rate was 0.42. Variables remaining significant at p < 0.05 in the multivariable model included: progressiveness strata; pharmacy type; scores on the facilitators scale; responses to two potential barriers items; scores on the patient/caregiver delivery strategies sub-scale; providing MTM at multiple locations; reporting that the MTM vendor sending the survey link is the primary MTM vendor for which the respondent provides MTM; and the number of hours per week that the pharmacy is open.
Conclusions
Factors at the respondent (e.g., responses to facilitators scale) and pharmacy (e.g., pharmacy type) levels were associated with CMR completion rates. These findings could be used by MTM stakeholders to improve CMR completion rates
Lesson Learned in the Growth and Maturation Stages of a Community Pharmacy Practice-Based Research Network: Experiences of the Medication Safety Research Network of Indiana (Rx-SafeNet)
Community pharmacy practice-based research networks (CP PBRNs) are a relatively new arena for pharmacists. While some lessons may be gleaned from primary care PBRNs, the experiences of CP PBRNs have much to offer the profession in terms of organization and practice. In 2012, we reported on our early experiences developing the Medication Safety Research Network of Indiana (RxSafeNet) after establishing the Network in 2010. Over the past 3 years, our CP PBRN of approximately 180 members has managed further growth by revisiting policies and procedures, maintaining CP PBRN member relationships, and preparing for financial sustainability. We look forward to furthering our CP PBRN projects in the coming years and collaborating with other CP PBRNs to enhance medication safety in Indiana and beyond.

An evaluation of the spread and scale of PatientTocâ„¢ from primary care to community pharmacy practice for the collection of patient-reported outcomes: A study protocol
Background Medication non-adherence is a problem of critical importance, affecting approximately 50% of all persons taking at least one regularly scheduled prescription medication and costing the United States more than $100 billion annually. Traditional data sources for identifying and resolving medication non-adherence in community pharmacies include prescription fill histories. However, medication possession does not necessarily mean patients are taking their medications as prescribed. Patient-reported outcomes (PROs), measuring adherence challenges pertaining to both remembering and intention to take medication, offer a rich data source for pharmacists and prescribers to use to resolve medication non-adherence. PatientTocâ„¢ is a PROs collection software developed to facilitate collection of PROs data from low-literacy and non-English speaking patients in Los Angeles. Objectives This study will evaluate the spread and scale of PatientTocâ„¢ from primary care to community pharmacies for the collection and use of PROs data pertaining to medication adherence. Methods The following implementation and evaluation steps will be conducted: 1) a pre-implementation developmental formative evaluation to determine community pharmacy workflow and current practices for identifying and resolving medication non-adherence, potential barriers and facilitators to PatientTocâ„¢ implementation, and to create a draft implementation toolkit, 2) two plan-do-study-act cycles to refine an implementation toolkit for spreading and scaling implementation of PatientTocâ„¢ in community pharmacies, and 3) a comprehensive, theory-driven evaluation of the quality of care, implementation, and patient health outcomes of spreading and scaling PatientTocâ„¢ to community pharmacies. Expected impact This research will inform long-term collection and use of PROs data pertaining to medication adherence in community pharmacies
Preliminary neurocognitive finding from a multi-site study investing long-term neurological impact of COVID-19 using ultra-high field 7 Tesla MRI-based neuroimaging
Background: Globally, over six hundred million cases of SARS-CoV-2 have been confirmed. As the number of individuals in recovery rises, examining long-term neurological effects, including cognitive impairment and cerebral microstructural and microvascular changes, has become paramount., We present preliminary cognitive findings from an ongoing multi-site study investigating the long-term neurological impacts of COVID-19 using 7 Tesla MRI-based neuroimaging.
Methods: Across 3 US and 1 UK sites, we identified adult (\u3e=18) COVID-19 survivors (CS) and healthy controls (HC) without significant pre-existing medical, neurological, or psychiatric illness. Using the National Alzheimer’s Coordinating Center (NACC) Uniform Data Set (UDS-3) battery and Norms Calculator, 12 cognitive scores were adjusted for age, sex, and education and classified as either unimpaired or mild (\u3c9th percentile), moderate (\u3c2nd percentile), or severely impaired (\u3c1st percentile). The observed frequency of impairment across the two groups is reported along with proportional differences (PD) and confidence intervals (CI). Illness severity and time since infection were evaluated as potential associates of cognitive impairment.
Results: Over a period of 11 months, we enrolled 108 participants. At the time of reporting, 80 (46.3% female; mean age: 60.3 ± 8.6; 61 CS, 19 HC) had completed cognitive assessments. Of the participants for whom we ascertained time since symptom onset and illness severity (n=51 and 43, respectively), 31.4% had their index COVID-19 infection within the past year, and 60.5% had a severe to critical infection (Table 1). Table 2 reports observed frequency of impairment for each metric. Aggregating all 12 cognitive metrics, we found 45 (73.8%) of CS had at least one impairment [vs HC: 10 (52.6%)]. A significantly greater proportion of CS had at least one moderate to severe or severe impairment (Figure 1). CS also had significantly higher frequencies of presenting with two or more mild to severe impairments [PD 0.33 (0.13, 0.54)]. Illness severity and time since infection were not significantly associated with cognitive impairment.
Conclusion: Our preliminary results are consistent with potentially sustained COVID-associated cognitive impairment in a subset of participants. Enrollment in the multi-site cohort is ongoing, and updated results will be presented along with ultra-high field MRI-based neuroimaging correlates
Preparing for the spread of patient-reported outcomes (PROs) data collection from primary care to community pharmacy: stakeholder insights
Medication non-adherence is a significant public health problem. Patient-reported outcomes (PROs) offer a rich data source to facilitate resolution of medication non-adherence. PatientTocâ„¢ is an electronic PRO data collection software originally implemented at primary care practices in California, United States (US). Currently, the use of standardized PRO data collection systems in US community pharmacies is limited. Thus, we are conducting a two-phase evaluation of the spread and scale of PatientTocâ„¢ to US Midwestern community pharmacies. This report focuses on the first phase of the evaluation. The objective of this phase was to prepare for implementation of PatientTocâ„¢ in community pharmacies by conducting a pre-implementation developmental formative evaluation to (1) identify potential barriers, facilitators, and actionable recommendations to PatientTocâ„¢ implementation and (2) create a draft implementation toolkit
Extreme oceanographic forcing and coastal response due to the 2015-2016 El Nino
The El Niño-Southern Oscillation is the dominant mode of interannual climate variability across the Pacific Ocean basin, with influence on the global climate. The two end members of the cycle, El Niño and La Niña, force anomalous oceanographic conditions and coastal response along the Pacific margin, exposing many heavily populated regions to increased coastal flooding and erosion hazards. However, a quantitative record of coastal impacts is spatially limited and temporally restricted to only the most recent events. Here we report on the oceanographic forcing and coastal response of the 2015–2016 El Niño, one of the strongest of the last 145 years. We show that winter wave energy equalled or exceeded measured historical maxima across the US West Coast, corresponding to anomalously large beach erosion across the region. Shorelines in many areas retreated beyond previously measured landward extremes, particularly along the sediment-starved California coast
A Common Network of Functional Areas for Attention and Eye Movements
AbstractFunctional magnetic resonance imaging (fMRI) and surface-based representations of brain activity were used to compare the functional anatomy of two tasks, one involving covert shifts of attention to peripheral visual stimuli, the other involving both attentional and saccadic shifts to the same stimuli. Overlapping regional networks in parietal, frontal, and temporal lobes were active in both tasks. This anatomical overlap is consistent with the hypothesis that attentional and oculomotor processes are tightly integrated at the neural level
