P-27. Impact of RSV( respiratory syncytial virus) Infection at ALM-VA

Abstract Background RSV infections, known for their respiratory complications, present a unique challenge in healthcare settings. Respiratory syncytial virus (RSV) causes substantial morbidity and mortality in older adults, resulting in approximately 60,000–160,000 hospitalizations and 6,000–10,000 deaths annually among adults aged ≥65 years Methods Retrospective review of the RSV cases from January 1, 2022 to October 27, 2023, at the South Texas Veterans healthcare system. We collected data(age and outcome of patients) from Theradoc (infection control surveillance tool used for surveillance) on positive RSV patients seeking care at South Texas Veterans Health Care System including the age of the positives, whether they had respiratory symptoms, were admitted to the hospital, and whether this admission was related to the respiratory symptoms. Results 130 patients with positive RSV( by Biofire or Fluvid RSV PCR) were studied. The mean age of the population was 61.7 years, with a standard deviation of 15.8 and a median of 63. Out of these, 73.8%(96/130) had only upper respiratory symptoms( Per CDC definition includes: rhinorrhea, cough, sneezing, nasal congestion) and 17.6% (23/130) had lower +/- upper respiratory symptoms.( Lower respiratory symptoms were defined as Tracheobronchitis, pneumonia, exacerbation of COPD, asthma, exacerbation of cardiac or neurological illness) 21.5%(28/130) of them were admitted due to some other reason but were found to be positive for RSV and 10.7%(14/130) of them were admitted due to RSV. Almost 61% (79/130)of them were aged 60 and above and out of those, RSV was the reason to seek care in 83.5%(66/79) of them. 83.3% (55/66) of them had upper respiratory symptoms and almost 26% of them had lower +/-upper respiratory symptoms. Almost 30%(23/79) of the patients over the age of 60 were admitted and RSV was the reason for admission in 53% (14/23) of them. Variables included the age of the positives, whether they had respiratory symptoms, were admitted to the hospital, and whether this admission was related to the respiratory symptoms Conclusion This project's findings will contribute to promoting the vaccination against RSV in patients older than 60 years of age and improving patient outcomes.

Healthcare capacity strengthening in conflict settings through virtual emergency medical training and outreach: Ukraine and Sudan case studies.

The use of digital learning in healthcare is expanding in a range of contexts including for settings of armed conflict. Humanitarian emergencies and war often lead to a surge of traumatic injuries, emotional distress, and disruption to health systems risking neglect and exacerbations of chronic illness, and acute infectious disease outbreaks, often requiring an international response. On the ground humanitarian response is often essential though logistical and security challenges can delay these responses, and the reliance on an international workforce unfamiliar with local cultures can create challenges in response efforts. In crises where local healthcare workers have limited training, or experience in emergency care, digital health care education can augment in-person response and training efforts. In recent years digital emergency care education programs have been deployed to both Ukraine and Sudan. A review of each of these programs demonstrates successes in and potential utility of remote healthcare capacity strengthening through digital education in settings of war. These programs provide important lessons in strengths of and challenges in developing and delivering just in time learning programs to settings of active armed conflict suggesting similar potential utility in a variety of humanitarian emergency contexts.

Long-Term Weight Loss and Comorbidity Resolution of Laparoscopic Sleeve Gastrectomy and Laparoscopic Roux-en-Y Gastric Bypass and the Impact of Preoperative Weight Loss on Overall Outcome.

The impact of preoperative weight loss on long-term weight loss outcomes and comorbidity resolution in both laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB) are poorly reported. Understanding this relationship is necessary to guide surgeons toward appropriate procedure and patient selection. The present study investigates long-term weight loss outcomes and comorbidity resolution following LSG and LRYGB and investigates the effect of preoperative variables on long-term outcomes. All patients who underwent LSG and LRYGB (2008-2022) in a tertiary referral centre were followed up prospectively. From 2010, a 12-week intensive preoperative information course (IPIC) became standard practice to optimize preoperative weight loss. Excess weight loss outcomes (EWL≥50% and ≥70%) were compared between LSG and LRYGB using multivariate logistic regression and the effect of preoperative weight loss on weight loss and comorbidity resolution, improvement, and exacerbation were reported. A total of 319 patients (median age: 49y; M:F, 75:244) were included (158 LSG: 161 LRYGB). During follow-up, 260 (81.5%) and 163 patients (51.1%) achieved EWL≥50% and ≥70%, respectively. Those with sustained EWL≥50% and EWL≥70% at the end of follow-up were more likely to have underwent a LRYGB versus a LSG (59.6% vs. 40.4%, P=0.002; 61.7% vs. 38.3%, P<0.001). IPIC and higher preoperative weight loss (HR: 2.59 to 3.72, P<0.001) increased rates of EWL≥50% and EWL70% for both procedures. Improvement or resolution of type-2 diabetes were significant (72.7%), but up to 27.3% of patients developed or suffered an exacerbation of a psychiatric illness. Excess weight loss outcomes are similar for LSG and LRYGB but LRYGB results in higher rates of sustained excess weight loss during long-term follow-up. Preoperative weight loss improves long-term weight loss. Comorbidity resolution is significant but rates of psychiatric illness exacerbation are high following metabolic and bariatric surgery.

Bolstering community resilience through health-focused climate change adaptation: moving from talk to action in Western Canadian communities

ABSTRACT The impacts of climate change have been recognized as a global health emergency. Worsening climate stressors are resulting in injury, illness and death. As this threat to health grows, so does the need to adapt. Climate change adaptation has been noted to reduce the risk of disease transmission, chronic illness exacerbation, physical trauma, and the mental health impacts associated with climate change. Cities across Western Canada have initiated the process of implementing health-focused climate change adaptation; however, progress has been slow, leaving communities vulnerable to health threats. Exploring five case study communities in Western Canada, this research sheds light on factors that enable and constrain progress on health-focused climate change adaptation. Research objectives are addressed through analysis of 16 key actor interviews (with experts in public health, planning, local governance, and other related fields), and a scan of relevant strategic planning documents. Results indicate that political will, expertise, and awareness has resulted in the development of health-focused climate change adaptation policy/ plans. However, implementation of these plans lags in practice. This lag stems from a lack of implementation detail in climate change adaptation plans, limited understanding of the impact of climate change on health, and jurisdictional confusion.

Anything is better than nothing’: exploring attitudes towards novel therapies in leukodystrophy clinical trials

Background/AimLeukodystrophies comprise a group of genetic white matter disorders that lead to progressive motor and cognitive impairment. Recent development of novel therapies has led to an increase in clinical trials for leukodystrophies. To enable recruitment of individuals with a leukodystrophy into clinical trials, clinical trial acceptability should be ascertained. We sought therefore, to identify the motivations for and barriers to clinical trial participation in addition to clinical trial features that may be of concern to individuals with a leukodystrophy and/or their carers.MethodsAdults with a leukodystrophy and parents/carers of individuals with a leukodystrophy were recruited through the Australian Leukodystrophy Registry and through online advertisements. Qualitative semi-structured interviews were used to explore participants views on what clinical trials involve, the perceived risks and benefits of clinical trials, their desire to participate in clinical trials and their personal experience with leukodystrophy. Thematic analysis of data was performed with co-coding of interview transcripts.Results5 interviews were held with parents of children with leukodystrophy, 4 with parents of adults with leukodystrophy and 3 with adults diagnosed with leukodystrophy. Motivations for clinical trial enrolment include access to potentially lifesaving novel treatments and improved prognostic outcomes. Participants were concerned about adverse clinical trial outcomes, including side effects and exacerbation of illness. Despite this, majority of participants were willing to try anything in clinical trials, demonstrating a high tolerance for first in human trials and trials utilising invasive treatment options.ConclusionsInterviewees communicated a strong desire to participate in interventional clinical trials involving novel therapies. To support enrolment into future leukodystrophy clinical trials we suggest the provision of transparent information regarding clinical trial treatments, consideration of alternative trial control measures, and inclusion of treating clinicians in the trial recruitment process. Clinicians play an integral role in initiating transparent conversations regarding trial risks and adverse outcomes.

Severe necrotizing tracheobronchitis caused by influenza B and methicillin-resistant Staphylococcus aureus co-infection in an immunocompetent patient

Purpose and methodNecrotizing tracheobronchitis is a rare clinical entity presented as a necrotic inflammation involving the mainstem trachea and distal bronchi. We reported a case of severe necrotizing tracheobronchitis caused by influenza B and methicillin-resistant Staphylococcus aureus (MRSA) co-infection in an immunocompetent patient.Case presentationWe described a 36-year-old man with initial symptoms of cough, rigors, muscle soreness and fever. His status rapidly deteriorated two days later and he was intubated. Bronchoscopy demonstrated severe necrotizing tracheobronchitis, and CT imaging demonstrated multiple patchy and cavitation formation in both lungs. Next-generation sequencing (NGS) and bronchoalveolar lavage fluid (BALF) culture supported the co-infection of influenza B and MRSA. We also found T lymphocyte and NK lymphocyte functions were extremely suppressed during illness exacerbation. The patient was treated with antivirals and antibiotics including vancomycin. Subsequent bronchoscopy and CT scans revealed significant improvement of the airway and pulmonary lesions, and the lymphocyte functions were restored. Finally, this patient was discharged successfully.ConclusionNecrotizing tracheobronchitis should be suspected in patients with rapid deterioration after influenza B infection. The timely diagnosis of co-infection and accurate antibiotics are important to effective treatment.

Original Research: Addressing Nurse Burnout: The Relationship Between Burnout and Physical Activity.

During the COVID-19 pandemic, nurses have faced innumerable challenges, which have contributed to staggering increases in burnout rates. In the health care arena, burnout has been associated with the onset or exacerbation of physical illness, neglect of self-care, fatigue, decreased patient satisfaction, higher medication error rates, lack of nurse engagement, and increased nurse turnover. This cross-sectional study sought to determine whether a correlation exists between self-reported physical activity and nurses' perception of burnout in a sample of hospital RNs. The secondary aim was to determine whether a correlation exists between the level of perceived burnout and the number of medication errors or near misses. Participants were asked to provide demographic information, complete the Copenhagen Burnout Inventory (CBI) and the Godin Leisure-Time Exercise Questionnaire (GLTEQ), and self-report the number of medication errors or near misses they were involved in during the previous 12 months. Data were analyzed using Stata version 17 software. A total of 216 participants returned usable surveys. Regarding the relationship between burnout and physical activity levels, data analysis was performed for the 210 participants who completed both the CBI and the GLTEQ. Compared with the least physically active nurses, the most active nurses had significantly lower CBI scores, with 68.5% of those reporting low or no burnout also scoring 24 or more on the GLTEQ. The least physically active nurses had significantly higher CBI scores, with 47.6% of those reporting high burnout also scoring 13 or less on the GLTEQ. Moreover, 90% of the nurses with high burnout levels had directly cared for COVID-19 patients at some point between 2020 and 2022. Medical-surgical nurses experienced significantly higher levels of burnout compared with nurses working in other service areas. No significant relationship was found between the number of medication errors or near misses and burnout levels. This study found that the most physically active nurses reported lower levels of burnout, while the highest levels of burnout were found in the least active nurses. Although COVID-19 infection rates have eased, many nurses, particularly those who have cared for COVID-19 patients and those who work in medical-surgical environments, continue to experience burnout. Targeted programs to reduce work-related burnout, as well as organizational sponsorship of and unit-level support for such programs, are urgently needed. This study's findings suggest that promotion of physical activity may be an essential component to alleviating burnout.

Efficacy, Effectiveness, and Safety of COVID-19 Vaccine Compared to Placebo in Preventing COVID-19 Infection among 12-17 Years Old: A Systematic Review.

The World Health Organization recently revised their recommendations and considered healthy children and adolescents as low priority group for COVID-19 vaccine. This review comprehensively assessed existing clinical evidence on COVID-19 vaccine in 12-17 years old. Included in this review were any type of study that investigated the efficacy, immunogenicity, safety, and effectiveness of COVID-19 vaccine on protection against SARS-COV-2 infection in 12-17 years old. Various electronic databases were searched up to March 15, 2023. Studies were screened, data extracted, risk of bias appraised, and certainty of evidence was judged using GRADE. Review Manager 5.4 was used to estimate pooled effects. Difference between the two groups was described as mean difference for continuous variables and as relative risk or odds ratio for categorical variables. There were six randomized controlled trials and 16 effectiveness studies (8 cohorts and 8 case control). Low certainty evidence showed that BNT162b2 (Pfizer) was effective, immunogenic, and safe in healthy adolescents. There were 15 effectiveness studies on BNT162b2 (Pfizer) in healthy adolescent and one on immunocompromised patients. It was protective against infection with any of the variants, with higher protection against Delta than Omicron. BNT162b2 is protective against hospitalization and emergency and urgent care (high certainty); and critical care and MIS-C (low). Very low certainty evidence noted that BNT 162b2 was also immunogenic in 12-21 years old with rheumatic diseases while on immunomodulatory treatment but with possible increased exacerbation of illness. Low certainty evidence demonstrated that mRNA-1273 (Moderna) was effective, immunogenic, and safe. Low to very low certainty evidence were noted on the safety and immunogenicity of two vector base vaccines (ChAdOx1-19 and Ad5 vector COVID vaccine) and two inactivated vaccines (CoronaVac and BBIBP CorV). There is presently low certainty evidence on the use of RNA vaccines in 12-17 years old. The recommendation on its use is weak. There is presently insufficient evidence for the use of inactivated and vector-based COVID-19 vaccines. Different countries should consider whether to vaccinate healthy adolescent without comprising the other recommended immunization and health priorities that are crucial for this age group. Other factors including cost-effectiveness of vaccination and disease burden should be accounted.

Task Force Dyspnoe unit (DU)

Acute dyspnoea is one of the most common internal medicine symptoms in the emergency department. It arises from an acute illness or from the exacerbation of a chronic illness. Symptom-related emergency structures and corresponding structural guidelines already exist in the stroke and chest pain units for dealing with the leading symptoms of acute stroke and acute chest pain. These are lacking in Germany for the key symptom of dyspnoea, although the benefits of these structures have already been proven in other countries. The German Society for Pneumology and Respiratory Medicine (DGP) has now set up a task force together with the Association of Pneumology Clinics (VPK), in order to deal with the topic and develop appropriate structural guidelines for such "dyspnoea units" in Germany. At the end of the process, the certification of such units at German hospitals is optional.

Adaptive Intervention to Prevent Respiratory Illness in Cerebral Palsy: Protocol for a Feasibility Pilot Randomized Controlled Trial.

This study will pilot-test an innovative just-in-time adaptive intervention to reduce severe respiratory illness among children with severe cerebral palsy (CP). Our intervention program, Respiratory Exacerbation-Plans for Action and Care Transitions (RE-PACT), delivers timely customized action planning and rapid clinical response when hospitalization risk is elevated. This study aims to establish RE-PACT's feasibility, acceptability, and fidelity in up to 90 children with severe CP. An additional aim is to preliminarily estimate RE-PACT's effect size. The study will recruit up to 90 caregivers of children with severe CP aged 0 to 17 years who are cared for by a respiratory specialist or are receiving daily respiratory treatments. Participants will be recruited from pediatric complex care programs at the University of Wisconsin-Madison (UW) and the University of California, Los Angeles (UCLA). Study participants will be randomly assigned to receive usual care through the complex care clinical program at UW or UCLA or the study intervention, RE-PACT. The intervention involves action planning, rapid clinical response to prevent and manage respiratory illness, and weekly SMS text messaging surveillance of caregiver confidence for their child to avoid hospitalization. RE-PACT will be run through 3 successively larger 6-month trial waves, allowing ongoing protocol refinement according to prespecified definitions of success for measures of feasibility, acceptability, and fidelity. The feasibility measures include recruitment and intervention time. The acceptability measures include recruitment and completion rates as well as intervention satisfaction. The fidelity measures include observed versus expected rates of intervention and data collection activities. The primary clinical outcome is a severe respiratory illness, defined as a respiratory diagnosis requiring hospitalization. The secondary clinical outcomes includehospital days and emergency department visits, systemic steroid courses, systemic antibiotic courses, and death from severe respiratory illness. The recruitment of the first wave began on April 27, 2022. To date, we have enrolled 30 (33%) out of 90 participants, as projected. The final wave of recruitment will end by October 31, 2023, and the final participant will complete the study by April 30, 2024. We will start analyzing the complete responses by April 30, 2024, and the publication of results is expected at the end of 2024. This pilot intervention, using adaptive just-in-time strategies, represents a novel approach to reducing the incidence of significant respiratory illness for children with severe CP. This protocol may be helpful to other researchers and health care providers caring for patients at high risk for acute severe illness exacerbations.

Non-pharmacological delirium detection and management interventions for informal caregivers of older people at home: A scoping review protocol.

The objective of this proposed scoping review is to identify and map the available evidence on interventions that aim to help informal caregivers identify and/or manage delirium in an older person at home. Delirium is a neurocognitive condition characterized by acute confusion and is associated with increased risk of morbidity and mortality. Research estimates delirium to be present in 17% of community-dwellers aged 85 and older, increasing proportionally with age to 45% in those aged 90 and older. Delirium often occurs at the onset of an older person's acute illness or exacerbation of a chronic illness (sometimes while at home) and, because of its protracted nature, usually continues after a hospital stay. Even when an older person's delirium resolves during hospitalization, they remain at risk of its recurrence after discharge home. Consequently, knowing how to detect and manage delirium is critical for informal caregivers of older people at home. However, there are no reviews focused exclusively on this topic in this setting. The population of interest includes informal caregivers of a person aged 65+. Concepts of interest include delirium detection and/or management interventions. The context of interest is any setting where informal care is delivered, including the transition from hospital to home, in any geographical area. The review will be conducted according to the JBI guidelines for scoping reviews. A three-step search strategy will be used to locate both published and unpublished papers in MEDLINE, Embase, CINAHL, PsycINFO, Web of Science Core Collection, ProQuest Nursing & Allied Health, SCOPUS, LILACS, and SciELO, PQD&T, NDLTD, Google Scholar and Google. No language restrictions will be placed on the review. Papers will be screened for eligibility at the title, abstract, and full text level by two independent reviewers. Data will be extracted by two independent reviewers and managed in Covidence. Any disagreements in screening or data extraction will be resolved by consensus or a third reviewer. Results will be summarised in narrative and tabular formats.

A Preliminary Study on the Impact of Household Air Pollution on Adult Respiratory Health in Urban and Rural Settings of Jaipur, India.

This study aimed to investigate the association between household air pollution and chronic respiratory illness (CRI) in Jaipur, India. A total of 147 participants over 18 years of age from 45 households were randomly included in the study, and follow-up visits were conducted once every fortnight over a three-month period. Spirometry tests were conducted using a portable hand-held digital spirometer. A self-designed, pretested, semi-structured questionnaire was utilized to collect socio-demographic information from the participants. Statistical tests, such as t-tests were used to analyze the association between household air pollution and CRI. The prevalence of COPD and bronchial asthma was 2% and 4%, respectively. Various risk factors for CRI were identified within households, and only 4 episodes of acute exacerbation of chronic respiratory illness were observed, resulting in no incidence density calculation. The mean values of forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) were significantly lower in females (P < 0.001) Also, the mean values of FVC and FEV1 were significantly lower in rural areas (P < 0.005) than urban areas. Our findings highlight the importance of government and stakeholder action to implement clean air policies and protect respiratory health. Further studies are needed to expand on these findings and delve deeper into understanding the complex interactions between various risk factors and respiratory health in this population.

Factors affecting adherence to psychotropics in trauma-affected refugees: data from a randomized controlled trial

Non-adherence to psychotropic drugs may reduce treatment effectiveness and may cause exacerbation of illness. Among migrant populations, studies have identified low adherence to psychotropic drugs. This study aimed to identify factors that were associated with the three basic components of adherence: non-initiation, non-implementation (blood sample), and discontinuation in a clinical sample of trauma-affected refugees diagnosed with posttraumatic stress disorder. The data for this study is derived from a randomized controlled trial (n = 108). Based on existing literature, individual sociodemographic and clinical candidate predictor variables that may affect the initiation, continuation, and implementation to psychotropics were selected as exposure variables. Logistic regression was used to assess the risk relation between non-initiation, non-implementation, discontinuation, and the individual sociodemographic and clinical factors. Three factors – level of education, turn-up rate for medical doctor sessions, and discomfort in relation to the psychotropics – were associated with non-initiation, non-implementation, or discontinuation. The relatively small sample size poses a limitation. Furthermore, factors not examined in the current study may have affected non-initiation, non-implementation, and discontinuation. The study identified level of education, turn-up rate for medical doctor sessions, and discomfort in relation to medicine as important factors in relation to treatment with psychotropics in trauma-affected refugees. Factors contributing to a low turn-up rate, and factors that are consequences of a low turn-up rate, as well as communication and trust in the patient-provider interaction need further research attention. Furthermore, there is a need for research on interventions addressing adherence for refugees with mental illness.

Integra at Home: A flexible continuum of in-home medical care for older adults with complex needs.

As individuals age, they may need new strategies to manage exacerbations of chronic disease to maintain their dignity and independence. Many end up in a revolving cycle of emergency department visits, hospitalizations, and post-acute care. Support to stay at home, which is often their preference, becomes a challenge and varies with insurance coverage, location, and financial status. There are few home-based options sufficiently agile enough to respond when acute conditions arise particularly with exacerbations of chronic disease. In 2018, Integra designed a home-based option to treat acute exacerbations of chronic illness. A partnership with community paramedicine enabled faster response times and provided additional treatment tools. Using process improvement methodology, we developed "Integra at Home" workflows and team-based care. We counted averted emergency visits and hospitalizations, patient and staff satisfaction, and evidence of financial sustainability as a result of our program. Integra successfully developed a suite of home-based services, including responses to acute problems, to address beneficiaries' fluctuating medical needs. Following responses to 415 acute events, 74% (N = 307) resulted in averted emergency department visits. Based on InterQual® criteria, 34% (N = 103) of averted visits would have qualified as an averted hospitalization. All 64 respondents to patient surveys (N = 170) stated they would recommend our program. The staff indicated the model is a better way of caring for patients with higher rewards than traditional settings. The average length of stay in hospice for patients referred from the program (N = 22) was 4 weeks. Home-based care continuums are feasible, yet resources to manage acute exacerbations remain inadequate. To fill this gap, we created higher acuity services to respond to urgent needs and monitor symptoms between episodes. Amid successes and challenges, we are serving higher acuity older adults in Integra's home-based continuum model. We encourage further spread of longitudinal home-based acute care models.

The Medication Use Issues and Challenges of Mental Illness Exacerbation in Patients with Schizophrenia: A Qualitative Study in Thailand.

Patients with schizophrenia often experience mental illness exacerbations, which lead to frequent re-hospitalization. Non-adherence to medication is the main cause of relapses, despite many patients requiring lifelong treatment. Non-adherence consequences include higher re-admission and suicide rates, worse progression of mental illness, higher rates of violence by patients with mental illness, and increased use of emergency psychiatric services. This directly impacts the cost and workload of the mental healthcare system. This study aims to understand medication non-adherence among schizophrenia patients in Thailand based on the country's specific context. This qualitative research study explored the causes of non-adherence to medication and health perceptions among patients with schizophrenia in Thailand. Five patients with schizophrenia were included in this study. Data was collected through in-depth interviews, recordings of treatments, and field notes based on the interpretive perspective of key informants with the concept of phenomenology. Thematic analysis revealed two main themes associated with mental illness exacerbation: triggers of exacerbation and medication non-adherence. The triggers that emerged from the data were substance abuse and psychological stress. Medication non-adherence issues were misunderstandings about mental illness and its treatment, lack of participation in treatment, and difficulty accessing mental health services. This study explored the importance of medication adherence in patients with schizophrenia. Non-adherence to medication can worsen mental illness and create a vicious cycle that makes treatment more challenging. Substance abuse and psychological stress can also exacerbate this cycle. Mental health services should strive to improve medication adherence strategies and offer social support to prevent harmful behaviors and break the vicious cycle.

Heat illness detection with heart rate variability analysis and anomaly detection algorithm

Objective:Incidence of heat illness has been increasing dramatically due to the progression of global warming. Preventing severe heat illness, called heatstroke, is crucial because it can lead to long-term multiple organ damage, including the brain, and results in more than 600 deaths per year in the United States. It has been reported that heat stress affects heart rate variability (HRV), which is the fluctuations of the R-R interval (RRI) on an electrocardiogram (ECG). We propose a method for detecting symptoms of heat illness based on HRV analysis in order to prevent exacerbation of heat illness. Methods:In the proposed method, monitoring abnormal changes in HRV caused by heat stress is monitored. Multivariate statistical process control (MSPC), a commonly used anomaly detection method in machine learning, is adopted for training the heat illness detection method. To validate the proposed method, we recruited 103 healthy volunteers with risks of heat illness development: employees working in hot environments, athletes, and amateur marathon runners. Data collection was performed using our wearable heart rate sensor and smartphone app. Results:The result of applying the proposed method showed that a sensitivity of 75% (21 out of 28 cases) and a false-positive rate of 1.02 times per hour were achieved. Conclusion:The proposed heat illness detection method will be used in daily life because RRI data can be easily measured by a wearable sensor. Significance:The proposed method will contribute to receiving appropriate treatment for heat illness before exacerbation, which contributes to protecting people’s health.

Psychiatric referrals to the general hospital emergency department: are we being effective?

General hospital emergency departments (GHEDs) are notoriously overcrowded. This is caused, in part, by ineffective referrals, that is to say referrals that do not require medical examination or other interventions in the context of a general hospital. This study aims to investigate the contribution of psychiatric referrals to this issue, to identify potential determinants of these referrals and offer means to reduce them. Retrospective data were collected from psychiatric admission files within a GHED of a tertiary-care city hospital over a 1 year period. Two experienced clinicians separately reviewed each file to determine rationale of referrals according to predetermined criteria. A total of 2,136 visits included a psychiatric examination, 900 (42.1%) were determined "effective," and 1,227 (57.4%) were deemed "potentially ineffective." The leading causes for potentially ineffective referrals to a GHED were psychiatric illness exacerbation (43.4%), and suicidal ideations (22%). Most referrals (66.9%) were initiated by the patient or their family, and not by a primary care physician or psychiatrist. More than half of the psychiatric referrals did not necessarily require the services of a general hospital, and may be more suitable for referral to a dedicated psychiatric facility. Ineffective referrals to the GHED pose a burden on general hospital resources, and may be less effective for the psychiatric patients. This calls for clear guidelines for the provision of optimal emergency treatment for mental-health patients.

Chatbot-assisted therapy for patients with methamphetamine use disorder: a preliminary randomized controlled trial.

Methamphetamine (MA) use disorder is associated with a large public health burden. Despite the therapeutic effects of psychosocial interventions based on current evidence, finding an approach to retain patients in treatment remains a real-world challenge. The rapid development of mobile health (mHealth) systems suggests the potential to provide real-time personalized care at any time and from any location, minimize barriers to treatment, maximize use, and promote the dissemination of accessible therapeutic tools in at-risk populations. Our study aimed to investigate the feasibility and effectiveness of chatbots for the treatment of MA use disorder. The inclusion criteria were (a) a diagnosis of MA use disorder as defined by the DSM-5, (b) age between 18 and 65 years, (c) no acute exacerbation of severe mental illness during the initial assessment, such as schizophrenia or bipolar I disorder, (d) willingness to participate in standard outpatient treatment for ≥ 6 months, and (e) an Android phone. Participants were randomly allocated to either a chatbot-assisted therapy via smartphone (CAT) group or a control group following simple randomization procedures (computerized random numbers) without blinding. All participants were followed up for 6 months. Treatment retention and monthly urine test results were analyzed as outcome measures. Participants' satisfaction with CAT was also assessed. In total, 50 and 49 participants were allocated to the CAT and control groups, respectively. There were no significant differences in retention time between the two treatment groups (df = 1, p = 0.099). The CAT group had fewer MA-positive urine samples than the control group (19.5% vs. 29.6%, F = 9.116, p = 0.003). The proportion of MA-positive urine samples was positively correlated with the frequency of MA use (r = 0.323, p = 0.001), severity of MA use disorder (r = 0.364, p < 0.001), and polysubstance use (r = 0.212, p = 0.035), and negatively correlated with readiness to change (r = -0.330, p = 0.001). Totally 55 participants completed the study at the 6-month follow-up and 60% reported relative satisfaction. Participants in this study had favorable acceptance and generally positive outcomes, which indicates that chatbot is feasible for treating people who use MA.
