A Generalizable Decision-Making Framework for Selecting Onsite versus Send-out Clinical Laboratory Testing.

BACKGROUND: Laboratory networks provide services through onsite testing or through specimen transport to higher-tier laboratories. This decision is based on the interplay of testing characteristics, treatment characteristics, and epidemiological characteristics. OBJECTIVES: Our objective was to develop a generalizable model using the threshold approach to medical decision making to inform test placement decisions. METHODS: We developed a decision model to compare the incremental utility of onsite versus send-out testing for clinical purposes. We then performed Monte Carlo simulations to identify the settings under which each strategy would be preferred. Tuberculosis was modeled as an exemplar. RESULTS: The most important determinants of the decision to test onsite versus send-out were the clinical utility lost due to send-out testing delays and the accuracy decrement with onsite testing. When the sensitivity decrements of onsite testing were minimal, onsite testing tended to be preferred when send-out delays reduced clinical utility by >20%. By contrast, when onsite testing incurred large reductions in sensitivity, onsite testing tended to be preferred when utility lost due to delays was >50%. The relative cost of onsite versus send-out testing affected these thresholds, particularly when testing costs were >10% of treatment costs. CONCLUSIONS: Decision makers can select onsite versus send-out testing in an evidence-based fashion using estimates of the percentage of clinical utility lost due to send-out delays and the relative accuracy of onsite versus send-out testing. This model is designed to be generalizable to a wide variety of use cases. HIGHLIGHTS: The design of laboratory networks, including the decision to place diagnostic instruments at the point-of-care or at higher tiers as accessed through specimen transport, can be informed using the threshold approach to medical decision making.The most important determinants of the decision to test onsite versus send-out were the clinical utility lost due to send-out testing delays and the accuracy decrement with onsite testing.The threshold approach to medical decision making can be used to compare point-of-care testing accuracy decrements with the lost utility of treatment due to send-out testing delays.The relative cost of onsite versus send-out testing affected these thresholds, particularly when testing costs were >10% of treatment costs.

Towards precision home visiting: results at six months postpartum from a randomized pilot implementation trial to assess the feasibility of a precision approach to Family Spirit.

BACKGROUND: Shared implementation challenges at scale in early childhood home visiting have led researchers to explore precision home visiting as a promising service delivery mechanism to better address families' unique needs and build greater program efficiencies. This randomized controlled pilot study aimed to assess the acceptability of a precision approach to one home visiting model, Family Spirit® and explore potential differences between Precision Family Spirit (PFS) and Standard Family Spirit (Standard FS) on participant-home visitor relationship and maternal outcomes. METHODS: Participants (N = 60) were at least 14 years old, pregnant or within 2 months postpartum, and enrolled in Family Spirit. Four sites in Michigan were randomized 1:1 to deliver PFS (up to 17 core lessons plus up to 13 additional lessons as needed) or Standard FS (home visiting services as usual). Primary (program acceptability, participant satisfaction, home visitor-participant relationship quality, retention, adherence) and secondary (knowledge, quality of life, difficulty with parenting problems, substance use, depression, stress) outcomes at 6 months postpartum are presented. PFS participants also self-reported on quality of life, difficulty with parenting problems, stress, substance use, and concerns with sexual and reproductive health and self and child's nutrition status at each home visit. This informed which lessons they should receive. RESULTS: Mothers in both groups reported positive program acceptability, satisfaction, and home visitor-participant relationships at 6 months postpartum. However, open-ended feedback from Standard FS participants indicates that some lesson content may not be applicable to all participants. At 6 months, retention was 82.3% for PFS and 66.7% for Standard FS, and adherence was 30.1% for PFS and 20.6% for Standard FS. CONCLUSIONS: Preliminary findings indicate that precision home visiting may be acceptable and feasible. A definitive trial is needed to build on this pilot data, assess outcomes for mothers and children participating in a precision approach to home visiting as compared to standard home visiting, and ready this approach for scale.

Measuring the effects of the COVID-19 pandemic on Diné and White Mountain Apache school personnel, families, and students: protocol for a prospective longitudinal cohort study.

BACKGROUND: This paper describes the protocol for a longitudinal cohort study, "Project SafeSchools" (PSS), which focuses on measuring the effects of COVID-19 and the return to in-person learning on Diné (Navajo) and White Mountain Apache (Apache) youth, parents, and educators. The early surges of the COVID-19 pandemic led to the closure of most reservation and border town schools serving Diné and Apache communities. This study aims to: (1) understand the barriers and facilitators to school re-opening and in-person school attendance from the perspective of multiple stakeholders in Diné and Apache communities; and (2) evaluate the educational, social, emotional, physical, and mental health impacts of returning to in-person learning for caregivers and youth ages 4-16 who reside or work on the Diné Nation and the White Mountain Apache Tribal lands. METHODS: We aim to recruit up to N = 200 primary caregivers of Diné and Apache youth ages 4-16 and up to N = 120 school personnel. In addition, up to n = 120 of these primary caregivers and their children, ages 11-16, will be selected to participate in qualitative interviews to learn more about the effects of the pandemic on their health and wellbeing. Data from caregiver and school personnel participants will be collected in three waves via self-report surveys that measure COVID-19 related behaviors and attitudes, mental health, educational attitudes, and cultural practices and beliefs for both themselves and their child (caregiver participants only). We hypothesize that an individual's engagement with a variety of cultural activities during school closures and as school re-opened will have a protective effect on adult and youth mental health as they return to in-person learning. DISCUSSION: The results of this study will inform the development or implementation of preventative interventions that may help Diné and Apache youth and their families recover from the negative impact of the COVID-19 pandemic, and positively impact their health and wellness.

Barriers to Unmarried Father Involvement During Infancy: Qualitative Study from Professionals' Perspectives.

Introduction Unmarried fathers in the U.S. face barriers to establishing a relationship with their newborn children that married fathers do not confront. Our study was implemented to determine how systems and services could be modified to better support the engagement of unmarried fathers. Methods We conducted interviews with 35 professionals who interact with primarily low-income unmarried mothers and fathers to elicit their perceptions of such barriers. We developed a social ecological model to inform the study design and used purposive sampling with chain referrals to ensure a wide breadth of perspectives. Themes and subthemes categorizing personal and environmental factors were placed within five nested categories corresponding to different levels of influence on unmarried fathers' behaviors: public policy, community, institutions, interpersonal relationships, and intrapersonal characteristics, and their intersections. Results Participants challenged as inaccurate the stereotype of unmarried fathers as disengaged and uninterested in being involved with their children. Rather, they described the marginalization and devaluing of unmarried fathers by government policies and family service systems and programs and also the dearth of resources available to them. They called on decision makers to adjust policies and services to be more inclusive of unmarried fathers, to promote father engagement more actively, and to urge direct service providers to respond to fathers as valued individuals. Discussion Adapting to the common reality of nonmarital childbearing will entail a systematic shift in the integration of ways in which we value, understand, include, and serve fathers.

In-Hospital Paternity Establishment: Experiences and Meaning Perceived by Unmarried Parents.

Voluntary paternity establishment was placed in birthing hospitals by an act of Congress, but little is known about how unmarried parents experience this process. This study presents reactions from 81 racially/ethnically diverse, low-income parents. A qualitative analysis of semi-structured interviews revealed three overall themes and six subthemes: (1) paternity establishment process [subthemes: variety of experiences, strong emotional experience, and poor timing]; (2) meaning of paternity establishment [subthemes: responsible fatherhood, symbol of commitment to child, and importance of the child knowing his father's identity]; and (3) paternity establishment decision-making. Many parents either did not recall receiving the requisite information or found it difficult to focus on technical materials immediately after childbirth. For parents, the symbolic value of the father's name on the birth certificate overrode other considerations. Parents' perspectives may help administrators of paternity establishment programs better tailor procedures and timing to the needs of unmarried parents.
