Kendala Provider Dan User Dalam Memanfaatkan Program Pelayanan Kegawatdaruratan Public Safety Center (PSC) 119 Di Kabupaten Tabanan
Authors: Viqtrayana I Putu Eka
Published: September 2021

Abstract

Background: Emergency conditions cannot be predicted at any time and require immediate help, so PSC 119 emergency services are here to help when handling victims, save lives, improve emergency services, and prevent them. After less than two years of implementing the Tabanan Serasi PSC 119 program, there are still many people in Tabanan Regency who do not know for sure about the existing PSC 119 services.

Objective: This study aims to determine the constraints of providers and users in utilizing the PSC 119 emergency service program in Tabanan Regency.

Methods: This study used a qualitative research design with an exploratory approach. This research was conducted in Unit PSC 119 of the Tabanan District Health Office in June-July 2020. The research data were analyzed using thematic methods. Data were collected through observation of the implementation, tracing documents and exploring 12 informants. Two main informants as providers are coordinator and implementer. Ten supporting informants as users, namely the community has not and have used it.

Results: The results showed that the use of PSC 119 in emergency services from providers/managers were, lack of procurement of infrastructure, human resource constraints, program structure position, round table, not yet utilizing call center 119, PSC operators lack of coordination with PSC 119 network. , do not have radiomedical equipment, and lack of monitoring and evaluation. Constraints from users/communities are contacting the 119 call center, public knowledge about PSC 119 services, and outreach activities. Strategies to overcome obstacles are to propose priorities according to the priority scale, seek human resources, seek infrastructure; training for implementing officers; implementation monitoring and evaluation; create innovation services; and socialize to the community about the program.

Conclusion: There are several obstacles to the use of PSC 119 in emergency services, both from providers/managers and users/communities, so the advice obtained is that the program manager continues to socialize, utilize existing personnel and make service innovations. The Tabanan District Health Office is expected to facilitate the implementation, carry out monitoring and evaluation of the PSC 119 program every year and improve the development and facilitate the program proposing PSC 119 to become a Technical Implementing Unit.

Development is the increase in the ability to function more complex bodies in a regular pattern. In the community, there are still many parents who do not know about their child's development, so that delays cannot be detected early. By providing stimulation, delays in child development can be detected and intervened early. The purpose of this study was to determine the relationship between the level of knowledge and the skills of mothers in stimulating gross motor skills of children aged 36-48 months. This type of research used associative with a cross sectional approach and using independent and dependent variables. Data collection using a questionnaire sheet. After the data collected is presented in a table and analyzed using the Spearman Rank statistical test. The results showed that the level of maternal knowledge about gross motor stimulation was at most 37.1% in the moderate category and maternal skills to stimulate gross motor skills at most 35.1% in the sufficient category where (r = 0.866, p = 0.000) so that there was a significant relationship between the level of knowledge with the mother's skills in stimulating gross motor skills. The conclusion of this study shows that the level of knowledge has a strong relationship with the skills of mothers in stimulating children's gross motor skills. Information about gross motor stimulation can be an effort to increase the knowledge and skills of mothers that can be done through counseling by health workers.

When the COVID-19 pandemic required all higher education learning to move to remote or online formats, students were challenged to maintain a sense of community and to advance in their education. By focusing on the immediate, human needs of students, IdeasCongress - a community-engaged experiential learning course with a curricular emphasis on transferable skills - flourished in the remote synchronous format. The only significant change was to shift the topic of the course to #RecoverTogether to guide our students in imagining a path through the pandemic while supporting local charities by developing plans for mitigating the impact that the pandemic was having on their service model. This paper outlines a case study of the course and reflections upon the experience of teaching during the pandemic restrictions, supported by student feedback from the September-December (Fall) 2020 semester. Based on this evidence, the approach appeared to be effective for student retention and engagement, and increased student feelings of connectedness to both the campus and the local community. The paper highlights key lessons learned while teaching and learning during challenging times and describe the teaching approaches used to support students.
Comparison of Water Absorption and Drying in Distal Radius Fracture Casts and Orthoses
Authors: White David Edward , John van Wyk Michael
Published: September 2021

Introduction:

Traditional plaster and fiberglass casts are not waterproof. This experimental study compares the water-resistant and drying properties of two commercially available orthoses with traditional cast liners.

Methods:

Two orthotic brace systems were selected for comparative waterproof testing with plaster and fiberglass traditional cast liners. This entailed water submersion for 10 seconds, followed by light drip drying for another 10 seconds. Moisture levels were then measured at four different locations immediately after drip drying and then every 15 minutes up to 45 minutes.

Results:

The Zero-Cast Wx orthosis retained the least moisture after initial immersion and was fully dry within 45 minutes. The Exos upper extremity brace also demonstrated a low initial mean moisture content but lost little moisture during drying. In comparison, both the cotton-lined plaster cast and Delta Dr. cast liner systems demonstrated the greatest amount of water absorbed and moisture retention.

Discussion:

Both orthotic brace systems demonstrated markedly less water absorption compared with the cotton-lined plaster cast and Delta Dr. cast liner systems. The Zero-Cast Wx was the only orthosis to fully dry in 45 minutes.

Conclusion:

Both orthotic brace systems provide superior water-resistant properties to traditional cotton-lined plaster cast or fiberglass Delta Dr. cast liner systems.

Published: September 2021

Five field experiments were conducted in Ontario Canada during 2018-2020 to determine the level of crop injury, weed control and white bean yield with up to four-way mixtures of herbicides applied preplant incorporated (PPI). The trials were arranged in a factorial design: Factor 1 was “Grass herbicide” including no grass herbicide, trifluralin, S-metolachlor and trifluralin + S-metolachlor and Factor 2 was “Broadleaf herbicide” including no broadleaf herbicide, halosulfuron, imazethapyr and halosulfuron + imazethapyr. At 2 and 4 weeks after emergence (WAE), there was minimal (≤ 4%) white bean injury. At 8 weeks after herbicide application (WAA), trifluralin, S-metolachlor or trifluralin + S-metolachlor averaged across Factor 2 controlled velvetleaf 69, 71 and 62%, respectively; halosulfuron, imazethapyr and halosulfuron + imazethapyr averaged across Factor 1 controlled velvetleaf 75, 95 and 97%, respectively. At 8 WAA, trifluralin, S-metolachlor and trifluralin + S-metolachlor controlled pigweed 93, 90 and 97%, respectively, and halosulfuron, imazethapyr and halosulfuron + imazethapyr controlled pigweed 97, 79 and 98%, respectively. At 8 WAA, trifluralin, S-metolachlor and trifluralin + S-metolachlor provided poor (≤ 32%) control of common ragweed while halosulfuron, imazethapyr and halosulfuron + imazethapyr controlled common ragweed 86, 53 and 87%, respectively. The 4-way tankmix of trifluralin, S-metolachlor, halosulfuron + imazethapyr controlled common ragweed 95%. At 8 WAA, trifluralin, S-metolachlor and trifluralin + S-metolachlor controlled common lambsquarters 81, 38 and 91%, respectively, and halosulfuron, imazethapyr and halosulfuron + imazethapyr controlled common lambsquarters 94, 97 and 99%, respectively. At 8 WAA, trifluralin, S-metolachlor and trifluralin + S-metolachlor provided poor (≤ 46%) control of wild mustard while halosulfuron, imazethapyr and halosulfuron + imazethapyr provided excellent (≥ 97%) wild mustard control. At 8 WAA, trifluralin, S-metolachlor and trifluralin + S-metolachlor controlled barnyardgrass 70, 85 and 94%, respectively, and halosulfuron, imazethapyr and halosulfuron + imazethapyr controlled barnyardgrass 9, 50 and 59%, respectively. At 8 WAA, trifluralin, S-metolachlor and trifluralin + S-metolachlor controlled green foxtail 89 to 98% and halosulfuron, imazethapyr and halosulfuron + imazethapyr controlled green foxtail 19, 69 and 67%, respectively. Weed interference reduced white bean yield 76%. Generally, white bean yield reflected the level of weed control. Based on these results, the 2- and 3-way tankmixes of herbicides evaluated generally provide similar weed control as the 4-way tankmixes.

Globally, vegetable production including tomato is constrained by pests and diseases. The tomato leafminer, Tuta absoluta (Meyrick.), is a major pest of tomato, mainly managed using chemical pesticides. There is a need for integrated pest management (IPM), approaches that are human and environmentally friendly. The study aimed at molecular identification and virulence evaluation of four entomopathogenic nematodes (EPNs) against T. absoluta larvae. The DNA was extracted, sequenced, and phylogeny analyzed. The EPNs virulence was evaluated using the insect baiting technique at different nematode concentrations (0-Control, 100, 150, 200, and 250 infective juveniles/ml of distilled water). Larval mortality data were collected for five days. Molecular identification resulted in nucleotide sequence lengths of 877-895 base pairs (bp). All the isolates were found to be Steinernema species of EPNs. The % similarity of the isolates and their close relatives ranged between 82-100%. The isolates closely matched Steinernema spp. AY230184 (Sri Lanka); AY230186 (Kenya), JN651414 (Ethiopia), and MW151701 (Kenya). The sequences were deposited to Genbank as Steinernema sp. Isolate Kalro 75 (MW150871), Steinernema sp. Isolate Kalro S86 (MW150872), Steinernema sp. isolate Kalro97 (MW150873) and Steinernema sp. Isolate KalroR52 (MW150874). All the EPN isolates were virulent against T. absoluta. Isolate Kalro R52 and Kalro S86 recorded the highest mortality of 76±7.5%; 72±15.0% respectively in the 48 h. There was a significant difference (P < 0.001), between all the isolates and the Control. The four EPNs were virulent and have bio-control potential against, T. absoluta. Research on their virulence against T. absoluta in the field is recommended.

Published: September 2021

For commercial soybean production, the presence of phosphorus in the soil is essential, not only to increase productivity but also because it affects basic functions in plant metabolism. Phosphate fertilizers have low efficiency in Cerrado soils. For this reason, the use of technologies associated with phosphate fertilizers is important to increase their efficiency in the soil. The experiment was conducted at Fazenda Rio Brilhante in Coromandel, MG. The experiment was laid out in a randomized block design in a 4 × 4 + 1 factorial arrangement. Treatments consisted of four phosphate fertilizer sources (MAPCONVENCIONAL, MAPpol 1, MAPpol 2, and FOM), four P2O5 doses (40, 80, 120, and 160 kg ha-1), and the control treatment (no phosphorus application). The soybean cultivar RK8115 IPRO with a plant population of 340 thousand plants per hectare was used. The experimental plots consisted of five planting lines with a spacing of 0.5 meters and a length of 7 meters. In the experiment, phosphorus leaf, morphological evaluation of plant height, stem diameter, number of stems, and pods were measured. For plant biomass, the dry matter of leaves, stems, and pods were determined. For yield evaluation, the calculation of productivity and RAE was compared with MAPCONVENCIONAL. For sources, data were subjected to analysis of variance, and means were separated by Tukey’s rate test (p < 0.05). For P2O5 doses, regression model fitting was performed using the ExpDes.pt package of R Studio software. Morphological assessments responded linearly to P doses, except for DPM. Leaves and pods P content and yield were affected by P dosage and P sources, with a quadratic response to P dosage. Maximum yield efficiency was achieved at P2O5 doses of 122.73; 145.07; 112.03; and 94.71 kg ha-1, with yields of 3818.30; 4064.67; 4089.03; and 3952.63 kg ha-1 for MAPCONVENCIONAL, MAPpol 2, MAPpol 1, and FOM, respectively. However, MAPpol 1 and FOM provided a dose reduction of 26 and 15 compared to the maximum yield of MAPCONVENCIONAL, respectively.

Published: September 2021

In genera Anastrepha, Bactrocera and Ceratitis of the tephritid fruit flies the auto-regulatory function of gene transformer is assumed to be activated by maternal derived mRNA or the proteins of the gene transformer (tra-2 mat) and transformer-2 (tra-2mat). However, this maternal effect was not yet been demonstrated. The objective of the present study was to test the effect of absence of tra-2mat in the eggs on the sex determination of A. sp.1 affinis fraterculus. This was achieved by silencing gene tra-2 in the parental females via the pRNA interference. The data showed that tra-2 was transiently silenced in the female for three weeks period. The progenies sex ratio produced by these females during the silencing of tra-2 depart from 1:1 in favor of males. The excess of males was due to the transformation of a fraction of genotypical female XX embryos into XX males, the so-called pseudomales, Individual F1 males from the offspring of treated females crossed to females from the stock, revealed that majority of them showed regular mating behavior and were fertile. However, no offspring was produced in the crosses by a fraction of males that have produced sperms, showed regular mating behavior but did not transfer sperms to the females. The data allow the conclusion that the absence of tra-2mat in the eggs had impaired the self-regulation of the embryonic gene tra resulting in the transformation of XX embryos into pseudomales and also that these pseudomales are sterile. This effect may be useful improve more sustainable technologies for fruit fly control such as SIT.

Libraries and Information Technology departments aim to support the educational
and research needs of students, researchers, and faculty members. Close matches between
the resources those departments provide and the resources the institution’s community
members actually use highlight the value of the departments, demonstrate fiscally
responsibility, and show attentiveness to the community’s needs. Traditionally,
libraries rely on usage statistics to guide collection development decisions, but usage
statistics can only imply value. Identifying a resource by name in a publication
demonstrates the value of that resource more clearly. This pilot project examined the
full-text of articles published in 2016-2017 by faculty members at a mid-sized,
special-focus institution to answer the questions “Do faculty members have
university-provided access to the research tools they need to publish?” and “If not,
where are they getting them?” Using a custom database, the presenters indexed every
publication by author, publication, resources used, availability of the identified
resources, and more. This pilot study can be adapted to projects at other institutions,
allowing them to gain a better understanding of the strengths and weaknesses of their
own institution’s offerings. In addition, they will be able to identify ways to use that
data to negotiate for additional resources, inform strategic partnerships, and
facilitate open discussions with the institution’s community.
Reference: Product Categories in the Digital Age
Authors: Earle Kathryn
Published: September 2021

In September of 2016, Bloomsbury Publishing Plc launched a new division charged
with creating digital resources for the academic library market. A number of these have
Reference at their core. This paper outlines in brief the logic for creating the new
division and the role of Reference within the resources. It then summarizes research we
have undertaken since the division’s inception to establish how ‘product categories’
(ie, encyclopedias, monographs, images etc) are valued by academics and librarians, the
aim of which is to create products that are user-focused. And finally this paper
provides a brief case study of our most mature resource, The Berg Fashion Library, to
ascertain how actual usage compares with how product categories are rated in the
research.
New usage reports, new insights! How to use your COUNTER data in decision making
processes
Authors: Hoeppner Athena , Lendi Sonja , Junge Kornelia
Published: September 2021

Librarians have been receiving COUNTER Release 5 reports since February 2019 and
are becoming familiar with the new robust usage data. In this paper three experts
explain how the new usage reports provide greater clarity and how they give insight into
users’ actions. Athena Hoeppner outlines the new reports and metrics and explains how to
interpret book usage data and how to use the data effectively in decision making
process. Sonja Lendi focuses on journal usage data and the differences between Release 4
and Release 5 of the COUNTER Code of Practice. She also explains Distributed Usage
Logging (DUL). This protocol enables publishers to capture traditional usage activity
related to their content that happens on sites other than their own so they can provide
reports of “total usage” regardless of where that usage happens. Kornelia Junge explains
how librarians can use Microsoft Excel to analyse usage.
Strategic Reinvestments of Journal Packages at the Pennsylvania State
University
Authors: Hosoi Mihoko
Published: September 2021

In the face of budget challenges, organizational strategy changes, and the new
open access (OA) policy, the Pennsylvania State University Libraries (PSUL) are
reevaluating negotiations and collections of ‘big deal’ journal packages. While a
growing number of libraries are considering cancelling subscriptions to ‘big deals’,
PSUL has been taking a careful approach in containing cost and making sure that faculty
and students have access to resources that they need. Current efforts include:
renegotiating ‘big deals’; cancelling low value titles in title-by-title agreements;
obtaining single agreements for the entire Penn State; promoting green OA for future
subscription negotiation purposes; and renegotiating OA related licensing terms. To
achieve greater efficiency of acquisitions workflows and increase university-wide
purchasing power, reallocation of the collection budget will be discussed in the near
future. Auto deposit of accepted manuscripts from any Penn State author into
ScholarSphere, Penn State’s institutional repository, as well as exploration of other OA
models are also under consideration.

Published: September 2021

In 2020, the world changed, experiencing a new scenario, resulting from the coronavirus pandemic, which spread rapidly, causing countless victims. This situation that still remains, caused a tragedy of epic proportions and, due to lack of preparation, especially on the part of health professionals, there were extreme measures, such as social isolation and the closing of borders in a desperate attempt to contain the spread of the disease. Due to this scenario, many business sectors were harmed, suffering losses and challenges, caused by the pandemic that spread quickly throughout the world. The present work aimed to present the challenges and impacts experienced by the Brazilian agribusiness in this coronavirus pandemic scenario. The study was carried out through bibliographical research based on articles, newspapers, magazines, coverage of texts posted on the internet and other wide and rapid dissemination means of virtual communication, which address the Covid-19 pandemic and its effects on this helping sector to sustain the Brazilian economy. Studies confirm that agribusiness in Brazil has once again proved to be a strong sector, showing good results amidst a period of economic downturn and numerous challenges in the face of the impacts of the pandemic.

Authors: Domingues Diego Munduruca , Soares Filipe Vilela , Lorenzi-Filho Geraldo , Moriya Henrique Takachi
Published: September 2021

Obstructive Sleep Apnea (OSA) is a syndrome characterized by episodes of airway obstruction, which causes oxygen desaturation events. These events can be identiﬁed by oximetry analysis and are used as one of the parameters to diagnose OSA. However, desaturation events have an inaccurate deﬁnition in manuals and in most of the literature. Thus, this work aims to evaluate whether different methodologies for the calculation of desaturation events impact the Oxygen Desaturation Index (ODI) and the diagnosis of OSA. The results indicated that the ODI values are signiﬁcantly different from each other (p <0.001) and the methodologies provided variable performance for the diagnosis of OSA.
Off-the-shelf 3D Lung Segmentation in CT using Generalized Histogram Thresholding
Authors: Toledo Marcelo A. F. de , Rebelo Marina F. S. , Krieger José E. , Gutierrez Marco A.
Published: September 2021

Computerized Tomography is very important for lung disease diagnostics, including computer assisted methods. Lung segmentation is usually a first step in further sophisticated methods of diagnosis. If in one hand, deep learning methods have state-of-the-art performance, they aren't as simple to apply compared to classical methods, sometimes requiring extra data and training. We designed a method specific for lung segmentation based on histogram thresholding. We observed that, in our proposed method, by changing from Otsu to the more recently developed GHT we got a significant improvement in segmentation, jumping from 77% to 91% average dice (from 90% to 95% median dice, respectively), approaching deep learning methods (UNet) results (94% average and 97% median dice). Even though our proposed method runs on CPU, it's still 2.6 times faster than UNet on GPU. Moreover, our proposed method is off-the-shelf, requiring no training or parameter calibration, being suitable as pre-processing for more sophisticated methods that aim specific diagnoses.

The world currently suffers from the global COVID-19 pandemic. Billions of people have been impacted, and millions of casualties have already occurred. Therefore, it is of extreme importance to identify individuals contaminated by SARS-CoV-2, allowing governments to plan actions to reduce further impacts. In this context, this work employed machine learning to improve the detection of SARS-CoV-2 antibodies in blood exams. Models have been developed in a real-world scenario with 500 thousand exams and were deployed in a remote laboratory for experiments. Results indicate that the models averaged sensitivity and speciﬁcity of 95%, and thus, they could aid COVID-19 antibody detection and the decision-making process of biomedical specialists.

Muitos problemas de classificação importantes são desbalanceados. Embora as abordagens de reamostragem sejam uma solução comum para diferentes tipos de problemas de classificação, elas ainda não foram definidas para problemas de classificação hierárquica. O objetivo deste trabalho é propor novas abordagens de reamostragem para lidar com a questão do desbalanceamento de classes em problemas de classificação hierárquica. Quatro direções foram investigadas: (i) O uso de métodos clássicos de reamostragem; (ii) Uma estratégia de conversão de caminho de rótulo; (iii) Esquemas para usar algoritmos de reamostragem com abordagens locais; (iv) impactos da Algoritmos de reamostragem globais. Para mostrar os contribuição deste trabalho, foi investigado o problema do desbalanceamento na identificação do COVID-19 em radiografias de tórax.

Com a utilização de sensores inteligentes em hospitais, o monitoramento e processamento dos dados é de extrema importância para melhorar serviços médicos. Em particular, esses dispositivos podem auxiliar na tomadas de decisões críticas. Nesse contexto, a qualidade do serviço (QoS) é essencial para garantir a conﬁabilidade dos dados das aplicações. Dito isso, esse artigo propõem HealthStack, um middleware para salas cirúrgicas com QoS automático e suporte a transmissão de dados em tempo real. O artigo propõe uma estratégia de QoS baseada em neurônios artiﬁciais para seleção dos componentes do middleware com baixa performance. Foi desenvolvido e testado um protótipo do modelo em uma sala de cirurgia real. A avaliação demonstra que a estratégia pode melhorar o jitter médio de aplicações em até 90,3%.

A pandemia do novo coronavírus tem sobrecarregado os sistemas de saúde ao limite da capacidade de atendimento. Nosso objetivo foi avaliar a eficácia de um chatbot desenvolvido para triagem de pacientes, antes de teleconsulta, para identificar sintomas de COVID-19. Sintomas informados no diálogo foram comparados com os relatados aos médicos, em um serviço de urgência. Em 96 pacientes, dispneia foi o sintoma mais frequente (16,6%) e o único que mostrou concordância moderada com a história registrada em prontuário eletrônico (Kappa=0,605). Concluindo, a tecnologia mostrou-se útil para detectar um dos sintomas graves da COVID-19, mas não foi possível evidenciar sua eficácia em relação aos sintomas menores.

Published: September 2021

Segundo o Censo de 2010 realizado pelo IBGE, 9,7 milhões de pessoas têm deﬁciência auditiva. Contudo, somente em 2002, através da Lei n. 10.436, que a Língua Brasileira de Sinais (Libras) foi reconhecida como segunda língua oﬁcial no Brasil. Diante disso, essa parte da população enfrenta diversos problemas de acessibilidade, sendo estes agravados pela falta de ferramentas que auxiliem as pessoas surdas em tarefas comuns do dia a dia. Deste modo, a proposta deste trabalho é desenvolver um dicionário colaborativo da Língua Brasileira de Sinais para que usuários falantes e aprendizes de Libras consigam colaborar na alimentação de sinais. O dicionário visa contemplar o regionalismo, bem como fornecer parâmetros que estruturam a formação da Libras nos diferentes níveis linguísticos.

Published: September 2021

Social isolation measures used worldwide to reduce the impacts of COVID-19 led many ofﬁce workers to work remotely with little notice. While researchers have studied remote collaboration for more than two decades, the scale and context of remote work during a pandemic is unprecedented and has changed personal and work dynamics. In this paper, we discuss a survey study investigating the impact of remote work during the COVID-19 pandemic in Brazil, informed by Olson & Olson's framework for distributed collaboration. We report preliminary ﬁndings from this study, focusing speciﬁcally on workers' wellbeing. Our results suggest that the main factors inﬂuencing workers' well beings are Common Ground Challenges, Collaboration Readiness, Collaboration Technology Readiness, Organizational Management, and Interruptions.

Published: September 2021

Introduction: Given the general lack of literature on opioid and naloxone prescribing guidelines for patients with substance use disorder, we aimed to explore how a physician’s behavior and prescribing habits are altered by knowledge of the patient’s concomitant use of psychotropic compounds as evident on urine and serum toxicology screens.

Methods: We conducted a retrospective chart review study at a tertiary, academic, Level I trauma center between November 2017–October 2018 that included 358 patients who were discharged from the emergency department (ED) with a diagnosis of fracture, dislocation, or amputation and received an opioid prescription upon discharge. We extracted urine and serum toxicology results, number and amount of prescription opioids upon discharge, and the presence of a naloxone script.

Results: The study population was divided into five subgroups that included the following: negative urine and serum toxicology screen; depressants; stimulants; mixed; and no toxicology screens. When comparing the 103 patients in which toxicology screens were obtained to the 255 patients without toxicology screens, we found no statistically significant differences in the total prescribed morphine milligram equivalent (75.0 and 75.0, respectively) or in the number of pills prescribed (15.0 and 13.5, respectively). Notably, none of the 103 patients who had toxicology screens were prescribed naloxone upon discharge.

Conclusion: Our study found no association between positive urine toxicology results for psychotropically active substances and the rates of opioid prescribing within a single-center, academic ED. Notably, none of the 103 patients who had toxicology screens were prescribed naloxone upon discharge. More research on the associations between illicit drug use, opioids, and naloxone prescriptions is necessary to help establish guidelines for high-risk patients.
