Description

Over the last two decades, opioid prescription and prevalence has increased to account for over 33,000 deaths per year (Soelberg, Brown, Du Vivier, Meyer & Ramachandran, 2017).

Over the last two decades, opioid prescription and prevalence has increased to account for over 33,000 deaths per year (Soelberg, Brown, Du Vivier, Meyer & Ramachandran, 2017). This is not only due to overdose, but misuse, abuse, and addiction. The abrupt increase in prescriptions, pills dispensed, and opioid-related deaths have encouraged the involvement of multiple entities.

In 2016, the opioid crisis gained the attention of communities that released guidelines to regulate prescription of opioid pain management. Such entities include the Center for Disease Control and Prevention (CDC), National Institute on Drug Abuse, Agency for Healthcare Research and Quality (AHRQ), Arizona Department of Health Services (AZDHS), and Substance Abuse and Mental Health Services Administration (SAMHSA). Evidence shows that prescribing practices between providers vary. It also shows that providers lack knowledge of appropriate opioid prescribing and management. To address this problem, provider education on an opioid policy is the most effective way to uniform opioid prescribing.

Primary health care clinics are essential first defenders determined to confront the upsurge in health-related leading causes of death in the United States. Unfortunately, the underserved or uninsured community continues to struggle to access these vital health care services. Consequently, this vulnerable population seeks venues such as community services events to obtain these unmet primary care services. Community services events effectively disseminate health-related material and provide access to vital medical services. Currently, community services strive to bridge the gap between underserved individuals and primary care clinics by providing participants referrals for low-fee or free clinics to establish ongoing care. A lack of data exists on whether these events sufficiently impact the participants to motivate them to follow-up with a health care clinic. A critical appraisal of evidence showed that follow-up adherence rates are remarkably improved by directly referring participants to a primary clinic during a community services event. This paper explores the effect on health outcomes and health disparities when establishing connections between community services participants and ongoing healthcare services.

Complex systems are pervasive in science and engineering. Some examples include complex engineered networks such as the internet, the power grid, and transportation networks. The complexity of such systems arises not just from their size, but also from their structure, operation (including control and management), evolution over time, and that people are involved in their design and operation. Our understanding of such systems is limited because their behaviour cannot be characterized using traditional techniques of modelling and analysis.

As a step in model development, statistically designed screening experiments may be used to identify the main effects and interactions most significant on a response of a system. However, traditional approaches for screening are ineffective for complex systems because of the size of the experimental design. Consequently, the factors considered are often restricted, but this automatically restricts the interactions that may be identified as well. Alternatively, the designs are restricted to only identify main effects, but this then fails to consider any possible interactions of the factors.

To address this problem, a specific combinatorial design termed a locating array is proposed as a screening design for complex systems. Locating arrays exhibit logarithmic growth in the number of factors because their focus is on identification rather than on measurement. This makes practical the consideration of an order of magnitude more factors in experimentation than traditional screening designs.

As a proof-of-concept, a locating array is applied to screen for main effects and low-order interactions on the response of average transport control protocol (TCP) throughput in a simulation model of a mobile ad hoc network (MANET). A MANET is a collection of mobile wireless nodes that self-organize without the aid of any centralized control or fixed infrastructure. The full-factorial design for the MANET considered is infeasible (with over 10^{43} design points) yet a locating array has only 421 design points.

In conjunction with the locating array, a ``heavy hitters'' algorithm is developed to identify the influential main effects and two-way interactions, correcting for the non-normal distribution of the average throughput, and uneven coverage of terms in the locating array. The significance of the identified main effects and interactions is validated independently using the statistical software JMP.

The statistical characteristics used to evaluate traditional screening designs are also applied to locating arrays.

These include the matrix of covariance, fraction of design space, and aliasing, among others. The results lend additional support to the use of locating arrays as screening designs.

The use of locating arrays as screening designs for complex engineered systems is promising as they yield useful models. This facilitates quantitative evaluation of architectures and protocols and contributes to our understanding of complex engineered networks.

Homeless individuals encounter barriers such as lack of health insurance, increased cost of care and unavailability of resources. They have increased risk of comorbid physical disease and poor mental health. Depression is a prevalent mental health disorder in the US linked to increased risk of mortality. Literature suggests depression screening can identify high-risk individuals with using the patient health questionnaire (PHQ-9).

The objective of this project is to determine if screening identifies depression in the homeless and how it impacts healthcare access. Setting is a local organization in Phoenix offering shelter to homeless individuals. An evidence-based project was implemented over two months in 2019 using convenience sampling. Intervention included depression screening using the PHQ-9, referring to primary care and tracking appointment times. IRB approval obtained from Arizona State University, privacy discussed, and consent obtained prior to data collection. Participants were assigned a random number to protect privacy.

A chart audit tool was used to obtain sociodemographics and insurance status. Descriptive statistics used and analyzed using Intellectus. Sample size was (n = 18), age (M = 35) most were White-non-Hispanic, 44% had a high school diploma and 78% were insured. Mean score was 7.72, three were previously diagnosed and not referred. Three were referred with a turnaround appointment time of one, two and seven days respectively. No significant correlation found between age and depression severity. A significant correlation found between previous diagnosis and depression severity. Attention to PHQ-9 varied among providers and not always addressed. Future projects should focus on improving collaboration between this facility and providers, increasing screening and ensuring adequate follow up and treatment.

Adverse childhood experiences (ACEs) are traumatic events experienced during childhood that have negative effects starting as a child and extending into adulthood. The presence of multiple ACEs increases negative mental, physical, and behavioral health outcomes. Children of parents who have experienced ACEs are at a higher risk of experiencing ACEs

Adverse childhood experiences (ACEs) are traumatic events experienced during childhood that have negative effects starting as a child and extending into adulthood. The presence of multiple ACEs increases negative mental, physical, and behavioral health outcomes. Children of parents who have experienced ACEs are at a higher risk of experiencing ACEs themselves, creating an intergenerational cycle of trauma between parents and their children. Evidence suggests that parenting education can reduce the impact of ACEs and potentially eliminate poor health outcomes. The literature revealed that parenting education was found to increase parenting competency, which will in turn reduce the impact of ACEs on children.

The purpose of this evidence-based project is to evaluate parenting competency and parenting self-efficacy after implementing six parenting workshops. The workshop topics consist of: (a) stress management, (b) understanding trauma, (c) positive parenting, (d) positive discipline, (e) play, and (f) learning development and support. The workshops were delivered at a community residential facility for women seeking recovery from abuse, incarceration, chemical dependency and other life-controlling problems. Participants included 10 female residents.

Demographics, ACE scores, pre and post Parenting Sense of Competency Scale, and a post intervention satisfaction questionnaire and discussion were used to collect data from the participants. Mothers’ ACE scores ranged from 2-9. The parenting self-efficacy score increased in the subgroup that attended all six workshops. All of the mothers agreed that the workshops would help with parenting their children. The findings suggest that parenting education increases parenting knowledge and self-efficacy, and may reduce the impact of ACEs on children.

Purpose: Hispanics diagnosed with type 2 diabetes mellitus (DM) have poorer health outcomes than non-Hispanic whites. Approximately one- half of all Hispanic DM patients utilize community health clinics for their DM needs. Evidence suggests that using a culturally-tailored approach to DM education can uniquely improve health outcomes in this population.

Purpose: Hispanics diagnosed with type 2 diabetes mellitus (DM) have poorer health outcomes than non-Hispanic whites. Approximately one- half of all Hispanic DM patients utilize community health clinics for their DM needs. Evidence suggests that using a culturally-tailored approach to DM education can uniquely improve health outcomes in this population. The purpose of this evidence-based practice (EBP) project was to improve glycemic control in a medically underserved Hispanic community through a culturally-tailored DM education program.

Methods: This quasi-experimental pre/post design project was guided by the ACE Star Model and Leininger’s Theory of Cultural Care. The affiliated University’s IRB approved this project. The Diabetes Empowerment Education Program (DEEP) was implemented in a free, community clinic in a medically underserved area. Spanish speaking patients (n = 15) with A1C levels
> 8mg/dl were recruited to participate in a 6-week group educational program facilitated by community health workers. Outcomes included A1C levels, weight, and two surveys from the Michigan Diabetes Research Center - DM knowledge test and the DM empowerment scale.

Results: Paired sample t-tests were used to analyze the outcomes. The participants had an average pre-A1C of 8.82 mg/dl with post-A1C of 8.01 mg/dl (p = .028). Pre-knowledge test scores averaged 9.40 with post-test average of 12.07 (p < .001). Empowerment scores increased from 4.09 to 4.63 (p = .001). The reduction between the average pre-and post-weight measures were not statistically significant (p = .681).

Discussion: The implementation of a culturally-tailored DM educational program in a medically underserved community had a significant impact on reducing A1C levels, improving DM knowledge, and enhancing empowerment levels. Although the sample size was small and limited to one clinic, applying these programs can have a measurable clinical impact in the treatment of Hispanic DM patients. Future research can further exam how to duplicate this project on a larger scale and over a sustained period.
