Evaluation of a Transitional Patient Navigation Protocol for People Living With Hepatitis C Virus in the New York City Jail System

Abstract: We evaluated outcomes from a telephone-based transitional patient navigation (TPN) service for people living with hepatitis C virus (HCV) upon returning to the community after incarceration in New York City (NYC) jails. NYC Health + Hospitals/Correctional Health Services offered referrals for TPN services provided by the NYC local health department patient navigation staff. We compared rates of connection to care among people referred for TPN services with those who were not referred. People living with HIV had a higher connection to care rate at three months (65.0% vs 39.8%, p≤.05) and people with opioid use disorder had a higher connection rate at six months (55.1% vs 36.1%, p≤.05) compared with people without these conditions. However, there was not an improved connection to HCV care associated with referral to TPN services for the overall cohort. Further research, including qualitative studies, may inform improved strategies for connection to HCV care after incarceration.

Families' Perspectives on Social Services Navigation After Pediatric Urgent Care.

Interest is growing in clinic-based programs that screen for and intervene on patients' social risk factors, including housing, food, and transportation. Though several studies suggest these programs can positively impact health, few examine the mechanisms underlying these effects. This study explores pathways through which identifying and intervening on social risks can impact families' health. This qualitative study was embedded in a randomized clinical trial that examined the health impacts of participation in a social services navigation program. We conducted semi-structured interviews with 27 English or Spanish-speaking caregivers of pediatric patients who had participated in the navigation program. Interviews were analyzed using thematic analysis. Caregivers described 3 pathways through which the navigation program affected overall child and/or caregiver health: 1) increasing families' knowledge of and access to social services; 2) helping families connect with health care services; and 3) providing emotional support that reduced caregiver isolation and anxiety. Participants suggested that navigation programs can influence health even when they do not directly impact resource access. Social care programs may impact health through multiple potential pathways. Program impacts seem to be mediated by the extent to which programs increase knowledge of and access to social and health care services and support positive relationships between families and program personnel.

Hospital admissions among patients with Comorbid Substance Use disorders: a secondary analysis of predictors from the NavSTAR Trial

BackgroundIndividuals with substance use disorders (SUDs) frequently use acute hospital services. The Navigation Services to Avoid Rehospitalization (NavSTAR) trial found that a patient navigation intervention for hospitalized patients with comorbid SUDs reduced subsequent inpatient admissions compared to treatment-as-usual (TAU).MethodsThis secondary analysis extends previous findings from the NavSTAR trial by examining whether selected patient characteristics independently predicted hospital service utilization and moderated the effect of the NavSTAR intervention. Participants were 400 medical/surgical hospital patients with comorbid SUDs. We analyzed 30- and 90-day inpatient readmissions (one or more readmissions) and cumulative incidence of inpatient admissions through 12 months using multivariable logistic and negative binomial regression, respectively.ResultsConsistent with primary findings and controlling for patient factors, NavSTAR participants were less likely than TAU participants to be readmitted within 30 (P = 0.001) and 90 (P = 0.03) days and had fewer total readmissions over 12 months (P = 0.008). Hospitalization in the previous year (P < 0.001) was associated with cumulative readmissions over 12 months, whereas Medicaid insurance (P = 0.03) and index diagnoses of infection (P = 0.001) and injuries, poisonings, or procedural complications (P = 0.004) were associated with fewer readmissions. None of the selected covariates moderated the effect of the NavSTAR intervention.ConclusionsPrevious findings showed that patient navigation could reduce repeat hospital admissions among patients with comorbid SUDs. Several patient factors were independently associated with readmission. Future research should investigate risk factors for hospital readmission among patients with comorbid SUDs to optimize interventions.Trial RegistrationNIH ClinicalTrials.gov NCT02599818, Registered November 9, 2015 https://classic.clinicaltrials.gov/ct2/show/NCT02599818.

Cost Analysis of Short Messaging Service and Peer Navigator Interventions for Linking and Retaining Adults Recently Diagnosed With HIV in Care in South Africa.

Large proportions of people living with HIV (PLHIV) in sub-Saharan Africa are not linked to or retained in HIV care. There is a critical need for cost-effective interventions to improve engagement and retention in care and inform optimal allocation of resources. We estimated costs associated with a short message service (SMS) plus peer navigation (SMS+PN) intervention; an SMS-only intervention; and standard of care (SOC), within the I-Care cluster-randomized trial to improve HIV care engagement for recently diagnosed PLHIV. We employed a uniform cost data-collection protocol to quantify resources used and associated costs for each intervention. Compared with SOC, the SMS+PN intervention cost $1284 ($828-$2859) more per additional patient linked to care within 30 days and $1904 ($1158-$5343) more per additional patient retained in care at 12 months, while improving linkage by 24% (95% CI: 11 to 36) and retention by 16% (95% CI: 6 to 26). By contrast, the SMS-only intervention cost $198 ($93-dominated) more per additional patient linked to care and $697 ($171-dominated) more per additional patient retained in care but was not significantly associated with improvements in linkage (12%; 95% CI: -1 to 25) or retention (3%; 95% CI: -7 to 14) compared with SOC. The efficiency of the SMS+PN intervention could be improved by 46%, to $690 more per additional patient linked and $1023 more per additional patient retained in care, if implemented within the Department of Health using more efficient distribution of staff resources. Findings suggest that scale-up of the SMS+PN intervention could benefit patients, improving care and health outcomes while being cost-effective.

Real-Time LEO Satellite Clocks Based on Near-Real-Time Clock Determination with Ultra-Short-Term Prediction

The utilization of Low Earth Orbit (LEO) satellites is anticipated to augment various aspects of traditional GNSS-based Positioning, Navigation, and Timing (PNT) services. While the LEO satellite orbital products can nowadays be produced with rather high accuracy in real-time of a few centimeters, the precision of the LEO satellite clock products that can be achieved in real-time is less studied. The latter, however, plays an essential role in the LEO-augmented positioning and timing performances. In real-time, the users eventually use the predicted LEO satellite clocks, with their precision determined by both the near-real-time clock precision and the prediction time needed to match the time window for real-time applications, i.e., the precision loss during the prediction phase. In this study, a real-time LEO satellite clock determination method, consisting of near-real-time clock determination with ultra-short-term clock prediction is proposed and implemented. The principles and strategies of this method are discussed in detail. The proposed method utilized Kalman-filter-based processing, but supports restarts at pre-defined times, thus hampering continuous bias propagation and accumulation from ancient epochs. Based on the method, using Sentinel-3B GNSS observations and the real-time GNSS products from the National Center for Space Studies (CNES) in France, the near-real-time LEO satellite clocks can reach a precision of 0.2 to 0.3 ns, and the precision loss during the prediction phase is within 0.07 ns for a prediction time window from 30 to 90 s. This results in a total error budget in the real-time LEO satellite clocks of about 0.3 ns.

Care navigation addresses issues of tele-mental health acceptability and uptake in rural and remote Australian communities.

People living in rural and remote areas face substantial barriers to accessing timely and appropriate mental health services. In the Bowen Basin region of Queensland, Australia, barriers include: limited local providers, long waiting lists, unreliable telecommunication, and reluctance to trial telehealth. Isaac Navicare is a new, community co-designed care navigation service which addresses these barriers by coupling care navigation with supported telehealth, and referrals to mental health providers and other supports. We aimed to understand the reach and effectiveness of Isaac Navicare in improving access to mental health services and address an evidence gap on strategies for improving telehealth acceptability. This mixed-methods implementation science evaluation used the RE-AIM Framework. It involved a client database review, survey and semi-structured interviews with service users during the 12-month pilot from November 2021. 197 clients (128 adults, 69 minors) were referred to Navicare during the pilot. Half of adult clients were unemployed, meaning referral options were limited to low-cost or bulk-billed services. Participants described Navicare as supportive and effective in helping to access timely and appropriate mental health supports. Most clients who expressed a treatment modality preference selected face-to-face (n = 111, 85.4%), however most referrals were for telehealth (n = 103, 66.0%) due to a lack of suitable alternatives. The rapport and trust developed with the care navigator was critical for increasing willingness to trial telehealth. Barriers to telehealth included privacy issues, technical difficulties, unreliable internet/phone, and perceived difficulties developing therapeutic rapport. The supported telehealth site was under-utilised. The majority (88.3%, n = 182) of referrals to Navicare were from local health or community service providers or schools. Coupling supportive, individualised care navigation with tele-mental health provider options resulted in increased uptake and acceptance of telehealth. Many barriers could be addressed through better preparation of clients and improving promotion and uptake of the supported telehealth site. Attitudes towards telehealth have changed during the COVID-19 pandemic, however although the need exists, barriers remain to uptake. Telehealth alone is not enough. Coupling telehealth with other supports such as care navigation improves acceptance and uptake.

A novel single‐layer dual‐band circularly polarized metasurface antenna for maritime communications

AbstractIn this article, a novel single‐layer dual‐band circularly polarized (CP) metasurface antenna for maritime applications is proposed. The metasurface is composed of 4 × 4 hexagonal patches with two different sizes printed on one side of the low‐profile FR4 substrate, while a slot antenna is printed on the other side. A slit is etched in the middle of each hexagonal patch to enhance modal significance, forcing the current flows to be orthogonal to each other at different modes, generating CP waves as identified with characteristic modal analysis. The proposed antenna has been fabricated and measured. Simulated and measured results match well, of which the impedance bandwidth is 55.96% (4.8–8.53 GHz), 3 dB axial ratio bandwidth is 2.7% from 5.46 to 5.61 GHz with a maximum gain of 9.58 dBic and 8.2% from 7.86 to 8.53 GHz with a maximum gain of 9.02 dBic. The proposed antenna is structurally stable, and is applicable for maritime radio navigation and communication services.

This paper explores the implications of Indonesia's agreement to delegate the Flight Information Region (FIR) of air navigation services to Singapore, specifically in the airspace of the Riau and Natuna islands, as stated in Presidential Regulation Number 109 of 2022. Using the normative juridical method, this study examines the intricate details of the agreement, with a focus on its potential legal consequences for Indonesia's national and international obligations.Although Indonesia retains sovereignty over its territory, this analysis scrutinizes the nuanced provisions of the agreement and their implications, particularly in terms of the technical aspects of air traffic services provided by the Singapore Air Traffic Services Provider above Indonesia's territories, which the agreement does not explicitly delineate the responsibilities or shared consequences in law. The purpose of this paper is to elucidate Indonesia's increased responsibility under the new agreement and emphasize the importance of a careful approach to its implementation. By exploring the multifaceted dimensions of national and international interests, this study seeks to highlight the imperative for Indonesia to navigate the agreement prudently.Ultimately, this analysis aims to provide a comprehensive understanding of Indonesia's obligations, potential challenges, and essential considerations under the renewed agreement of 2022, underscoring the significance of a balanced approach in safeguarding Indonesia's interests on both national and international fronts.

Orbit determination of Earth-Moon libration point navigation constellation based on Inter-satellite links

Earth-Moon libration point navigation constellation has a merit of fully covering the cislunar space and providing navigation services with merely a small number of satellites. Furthermore, this type of constellation itself can achieve orbit determination by using only its Inter-satellite links (ISL) owing to the well-known gravitational asymmetry near the libration points. This paper adopts a representative four-satellite navigation constellation including three satellites located near the libration point L3, L4, L5, and an extra one in Distant Retrograde Orbit (DRO), and studies the orbit determination accuracy of the constellation under two conditions: establishing ISLs within itself (called Solely libration point satellites) and establishing additional ISLs with BeiDou Navigation Satellite System (BDS) (called Libration + BeiDou satellites). The simulation results indicate that, for the Solely libration point satellites scenario with the 1 m range error and solar radiation pressure (SRP) error with the level of 10% deviation between ball model and macro model, the final orbit accuracies for L3, L4, L5, and DRO satellites can respectively achieve 11.3 m, 12.7 m, 12.6 m, and 7.3 m. Reducing the link interval can significantly shorten the arc length to achieve final accuracy, whileas it has less impact on the final orbital accuracy. When the link interval is set as 240, 60, 10, and 2 min, the arc lengths at the final accuracy of better than 15 m are about 35, 29, 23, and 20 days, respectively. To balance the communication burden and the orbit determination arc length, the recommended ISL building interval is 10 min. Errors coming from range measurement model and dynamic model, in addition, are key factors in orbit determination, which can result in meters to tens of meters of orbital accuracy. For the Libration + BeiDou satellites scenario, the augmented ISLs to BDS can substantially improve constellation orbital accuracy and shorten the orbit determination arc length. When the DRO satellite attached to the Geostationary Earth Orbit (GEO), Inclined Geosynchronous Orbit (IGSO), and Medium Earth Orbit (MEO) satellites of BDS respectively, the improved accuracy are 37.1%, 61.2%, and 42.2%, while the shortened arc length are 20.1%, 28.3%, and 28.1%, respectively. The research findings presented in this paper can serve as a reference for the construction and assessment of navigation constellations in the Earth-Moon system.

Space classification for indoor pedestrian navigation with morphological and functional characteristics

AbstractIndoor navigation networks serve as the foundation for indoor pedestrian navigation services. However, current graph‐based topological network models cannot easily represent complex indoor structures in a manner consistent with user behaviour and cognitive patterns, and thus cannot support fine‐grained indoor navigation analysis services. To enhance the rationality of the model, we considered the influences of morphological and functional characteristics of indoor spaces on pedestrian movement and proposed a method for classifying navigation spaces. This method, based on convex space segmentation, defines morphological and functional characteristic functions, classifying indoor navigation spaces as either corridors or open spaces, which suitable for representing as median axis models or visual graphs, respectively. These categories supported the creation of topological network models for route planning analysis. Indoor map experiments confirmed the effectiveness of our method in identifying various types of corridors and open spaces, that addressing the limitations of width‐based parameters, even in complex indoor settings.

Improving Access to Care Through Youth-Focused Virtual Sexual Health Navigation

PurposeGender and sexually diverse adolescents and young adults in Baltimore City, Maryland, are disproportionately impacted by HIV. The Virtual and Online Integrated Sexual Health Services for Youth program is a health navigation program which combines virtual sexual health service delivery and health navigation to link youth at risk for HIV acquisition to HIV testing/prevention and sexual healthcare services. MethodsYouth between 13 and 26 years old and residing in the Baltimore area were eligible to participate in the program. Demographic and engagement data from 238 youth (average age 21.4, SD = 2.5) who requested navigation were collected and recorded in a Health Insurance Portability and Accountability Act (HIPAA)-secure medical database and examined for associations between demographics, referral source, and the number of navigational services to which they were linked. Focused populations were defined as residents of high HIV prevalence zip codes who identify as sexual and gender diverse youth. ResultsReceipt of navigational services was significantly associated with self-identifying as sexually diverse. A multivariate regression revealed a significant association between the count of navigational services a youth was linked to and recording one's sexual orientation, identifying as a cisgender male, and residing in a high HIV-prevalence zip code. DiscussionVirtual health navigation has the potential to engage priority populations, including sexual and gender diverse youth. By refining linkage and identification approaches to health navigation, future outreach attempts can be tailored to support vulnerable communities, with the potential to improve sexual healthcare access.

Determining the Antenna Phase Center for the High-Precision Positioning of Smartphones.

In recent years, smartphones have emerged as the primary terminal for navigation and location services among mass users, owing to their universality, portability, and affordability. However, the highly integrated antenna design within smartphones inevitably introduces interference from internal signal sources, leading to a misalignment between the antenna phase center (APC) and the antenna geometric center. Accurately determining a smartphone's APC can mitigate system errors and enhance positioning accuracy, thereby meeting the increasing demand for precise and reliable user positioning. This paper delves into a detailed analysis of the generation of Global Navigation Satellite System (GNSS) receiver antenna phase center errors and proposes a method for correcting the receiver antenna phase center. Subsequently, a smartphone positioning experiment was conducted by placing the smartphone on an observation column with known coordinates. The collected observations were processed in static relative positioning mode, referencing observations from geodetic-grade equipment, and the accuracy of the static relative positioning fixed solution was evaluated. Following weighted estimation, we determined the antenna phase center of the Xiaomi Mi8 and corrected the APC. A comparison of the positioning results of the Xiaomi Mi8 before and after APC correction revealed minimal impact on the standard deviations (STDs) but significant influence on the root mean square errors (RMSEs). Specifically, the RMSEs in the E/N/U direction were reduced by 59.6%, 58.5%, and 42.0%, respectively, after APC correction compared to before correction. Furthermore, the integer ambiguity fixing rate slightly improved after the APC correction. In conclusion, the determination of a smartphone's APC can effectively reduce system errors in the plane direction of GNSS positioning, thereby enhancing smartphone positioning accuracy. This research holds significant value for advancing high-precision positioning studies related to smartphones.

Patient navigation in women's health care for maternal health and noncancerous gynecologic conditions: a scoping review.

This study investigated the scope of patient navigation studies on women's health care for maternal health and noncancerous gynecologic conditions and aimed to report the characteristics of the identified patient navigation programs. A scoping review was conducted following Arksey and O'Malley's framework. Five electronic databases were searched for relevant studies published in English: PubMed, Embase, Cochrane Library, CINAHL, and PsycInfo. There were no restrictions on the publication date and the search was completed in July 2023. This scoping review included 14 studies, which collectively examined seven patient navigation programs. All selected studies were related to maternal health issues (e.g., perinatal health problems and contraception for birth spacing). Close to two-thirds of the patient navigation services were provided by women (n=9, 64.3%) and half by lay navigators (n=7, 50.0%). The majority incorporated the use of mobile health technologies (n=11, 78.6%). All of the patient navigation programs included in the review coordinated the necessary clinical and social support services to improve women's access to care. Patient navigation appears to be in its nascent phase in the field of maternal health. The results of this study suggest that the implementation of patient navigation services could potentially improve access to care for socially disadvantaged women and families. Furthermore, providing patient navigation services that are specifically tailored to meet women's needs could improve the quality of maternity care.

Using focus groups to inform a peer health navigator service for people who are transgender and gender diverse in Saskatchewan, Canada.

This study investigated healthcare access and quality for people who are transgender and gender-diverse (PTGD) in Saskatchewan (SK), Canada, to inform a larger project that was piloting two peer health navigators for PTGD. Two online focus groups were held. Nineteen participants were recruited to represent a broad range in age, gender and location in SK. Transcripts of the focus groups were analyzed using a thematic approach. The core theme that was identified was participants' desire for culturally safe healthcare. This core theme had two component themes: (1) systemic healthcare factors and (2) individual healthcare provider(HCP) factors. The healthcare system primarily acted as a barrier to culturally safe healthcare. HCPs could be either barriers or facilitators of culturally safe care; however, negative experiences outweighed positive ones. PTGD in SKface discrimination, with delays and barriers to care at all levels of the healthcare system. Peer health navigators can address some of these discrepancies; however, greater support is required for PTGD to be able to access culturally safe healthcare. People with lived experience/PTGD were involved in all stages of this project. They were included on the team as community researchers and co-developed the research project, conducted the focus groups, participated in the analyses and are co-authors. As well, both navigators and all the participants in the focus groups were also PTGD.

Access to Healthcare Among Young Adult Probationers Participating in a Pilot Health-Focused Reentry Program.

Justice-involved adults experience disparities in healthcare access. This pilot study examines healthcare access among young adult probationers (n = 66) receiving 6-months of Service Navigation and Health Coaching support implemented between 2017 and 2021. Data are from baseline, 6-month follow-up and satisfaction surveys. Between baseline and follow-up, the proportion of insured young adult participants (66%-88%; p < .001) and those using healthcare services (36%-71%; p < .001) increased significantly; report of unmet physical healthcare needs decreased significantly (44%-26%; p = .003). Satisfaction data revealed increased self-efficacy, motivation, focus, and improved organizational, goal setting, and communication skills. The program improved healthcare access by increasing health insurance and recent use of healthcare services. Longitudinal studies are needed to assess maintenance of these outcomes and potential impacts on disparities in health status and access to care indicators. Integrating navigation and coaching supports to advance the well-being of justice-involved young adults is a promising mechanism to facilitate healthcare access.

Архитектурное решение проектирования сервисов пространственно-временной навигации в образовательных учреждениях

The paper presents an architectural solution to the problem of including navigation services in the already existing information system of the university. The relevance of the study is due to the modern development of indoor navigation technologies and the widespread prevalence of mobile services. The problem statement considers the multi-level architecture of the university IS and its functional logical model in relation to the concept of creating an adaptive educational environment. Based on this, the need to use microservices and APIs for space-time navigation in a university environment is justified. The presented justification of the selected design solutions is based on the proposed generalized scenario of internal navigation in the university, including the setting and construction of routes. Movement at the university is determined by the schedule of events, which implies space-time tracking depending on the role of the user and the infrastructure of buildings. The generalization of our experience in implementing various applications using navigation and location, as well as the results of the modeling of use cases from various points of view, allowed us to build a domain model. It has been proven that such an organization of the data model can be generated from the information structure of the portal and other external systems. Based on the described design solutions, a microservice architecture for a space-time navigation system with a public API has been developed. The key advantage of this approach is not only ample opportunities to support various university activities, but also the creation of infrastructure mechanisms for the modernization and development of the information and educational ecosystem.
