ABSTRACT

BACKGROUND: Working with eHealth requires health care organizations to make structural changes in the way they work. Organizational structure and process must be adjusted to provide high-quality care. This study is a follow-up study of a systematic literature review on optimally organizing hybrid health care (eHealth and face to face) using the Donabedian Structure-Process-Outcome (SPO) framework to translate the findings into a modus operandi for health care organizations.

OBJECTIVE: This study aimed to develop an SPO-based quality assessment model for organizing hybrid health care using an accompanying self-assessment questionnaire. Health care organizations can use this model and a questionnaire to manage and improve their hybrid health care.

METHODS: Concept mapping was used to enrich and validate evidence-based knowledge from a literature review using practice-based knowledge from experts. First, brainstorming was conducted. The participants listed all the factors that contributed to the effective organization of hybrid health care and the associated outcomes. Data from the brainstorming phase were combined with data from the literature study, and duplicates were removed. Next, the participants rated the factors on importance and measurability and grouped them into clusters. Finally, using multivariate statistical analysis (multidimensional scaling and hierarchical cluster analysis) and group interpretation, an SPO-based quality management model and an accompanying questionnaire were constructed.

RESULTS: All participants (n=39) were familiar with eHealth and were health care professionals, managers, researchers, patients, or eHealth suppliers. The brainstorming and literature review resulted in a list of 314 factors. After removing the duplicates, 78 factors remained. Using multivariate statistical analyses and group interpretations, a quality management model and questionnaire incorporating 8 clusters and 33 factors were developed. The 8 clusters included the following: Vision, strategy, and organization; Quality information technology infrastructure and systems; Quality eHealth application; Providing support to health care professionals; Skills, knowledge, and attitude of health care professionals; Attentiveness to the patient; Patient outcomes; and Learning system. The SPO categories were positioned as overarching themes to emphasize the interrelations between the clusters. Finally, a proposal was made to use the self-assessment questionnaire in practice, allowing measurement of the quality of each factor.

CONCLUSIONS: The quality of hybrid care is determined by organizational, technological, process, and personal factors. The 33 most important factors were clustered in a quality management model and self-assessment questionnaire called the Hybrid Health Care Quality Assessment. The model visualizes the interrelations between the factors. Using a questionnaire, each factor can be assessed to determine how effectively it is organized and developed over time. Health care organizations can use the Hybrid Health Care Quality Assessment to identify improvement opportunities for solid and sustainable hybrid health care.

ABSTRACT

BACKGROUND: During the COVID-19 pandemic period, the level of anxiety and the duration of social media use increased in university students.

OBJECTIVES: This study aimed to examine the relationship between coronavirus anxiety and social media addiction in university students.

METHODS: The sample consisted of 346 university students in Turkey. The data were collected online using the Sociodemographic Data Form, the Coronavirus Anxiety Scale Short Form and the Social Network Addiction Scale. The data were analysed using one-way analysis of variance, Mann-Whitney U test, Pearson correlation analysis, chi-square analysis and multiple linear regression analysis.

RESULTS: The results showed that the mean coronavirus anxiety score was higher in men than in women. Social media addiction increased as the daily time spent by the students on social media increased. A positive correlation was found between the daily time spent on social media before the pandemic and social media usage during the pandemic. It was concluded that students use social media more during the pandemic than before it and that social media addiction increases as the students’ coronavirus anxiety increases.

CONCLUSION: It is important to plan initiatives to reduce coronavirus anxiety to prevent social media addiction in young people.

STUDY LOCATION AND SAMPLE: The research population consisted of 1st and 2nd year students who are studying in the Medical Services and Techniques Department of Vocational School of Health Services at a university located in the west of Turkey, during the Fall Term of academic year 2020-2021. Students in this department are studying in anaesthesia, dialysis, first and emergency aid, medical laboratory techniques, medical imaging technique, and medical documentation and secretarial programmes.

ABSTRACT

BACKGROUND AND OBJECTIVES: Blood cultures are vital diagnostic tests that detect harmful pathogens in a patient’s bloodstream. In this study, we implemented a process-driven quality improvement program to reduce blood culture contamination rates.

METHODS: St Joseph Health (SJH) utilized the ISO 9001:2015 Internal Audit tool, failure mode effect analyses, and the Centers for Disease Control and Prevention’s Hierarchy of Controls to identify opportunities for improvement and design effective corrective and preventive action plans. These actions included reeducation and ongoing coaching of staff on the blood culture collection process, reorganizing blood culture supplies on the nursing units, and adding multiple layers of supervision.

RESULTS: A statistically significant relationship was identified between 2 variables (“contamination rate” and “cumulative cost difference”). The 2 variables had a negative association, demonstrating that as the contamination rate decreased, the cumulative cost difference increased, indicating potential cost savings.

CONCLUSION: The estimated value added to the institution through this initiative was approximately $215 743 to $228 543 in potential cost savings. SJH significantly reduced the number of blood culture contaminations in the critical care division, evidenced by a controlled 6-month mean below 1%. Review of the 6-month mean as a reference point demonstrated the sustainability of the implemented corrective and preventive measures.

ABSTRACT

IMPORTANCE: Electroacupuncture (EA) is a widely recognized therapy for depression and sleep disorders in clinical practice, but its efficacy in the treatment of comorbid insomnia and depression remains uncertain.

OBJECTIVE: To assess the efficacy and safety of EA as an alternative therapy in improving sleep quality and mental state for patients with insomnia and depression.

DESIGN, SETTING, AND PARTICIPANTS: A 32-week patient- and assessor-blinded, randomized, sham-controlled clinical trial (8-week intervention plus 24-week observational follow-up) was conducted from September 1, 2016, to July 30, 2019, at 3 tertiary hospitals in Shanghai, China. Patients were randomized to receive EA treatment and standard care, sham acupuncture (SA) treatment and standard care, or standard care only as control. Patients were 18 to 70 years of age, had insomnia, and met the criteria for depression as classified in the Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition). Data were analyzed from May 4 to September 13, 2020.

INTERVENTIONS: All patients in the 3 groups were provided with standard care guided by psychiatrists. Patients in the EA and SA groups received real or sham acupuncture treatment, 3 sessions per week for 8 weeks, for a total of 24 sessions.

MAIN OUTCOMES AND MEASURES: The primary outcome was change in Pittsburgh Sleep Quality Index (PSQI) from baseline to week 8. Secondary outcomes included PSQI at 12, 20, and 32 weeks of follow-up; sleep parameters recorded in actigraphy; Insomnia Severity Index; 17-item Hamilton Depression Rating Scale score; and Self-rating Anxiety Scale score.

RESULTS: Among the 270 patients (194 women [71.9%] and 76 men [28.1%]; mean [SD] age, 50.3 [14.2] years) included in the intention-to-treat analysis, 247 (91.5%) completed all outcome measurements at week 32, and 23 (8.5%) dropped out of the trial. The mean difference in PSQI from baseline to week 8 within the EA group was -6.2 (95% CI, -6.9 to -5.6). At week 8, the difference in PSQI score was -3.6 (95% CI, -4.4 to -2.8; P < .001) between the EA and SA groups and -5.1 (95% CI, -6.0 to -4.2; P < .001) between the EA and control groups. The efficacy of EA in treating insomnia was sustained during the 24-week postintervention follow-up. Significant improvement in the 17-item Hamilton Depression Rating Scale (-10.7 [95% CI, -11.8 to -9.7]), Insomnia Severity Index (-7.6 [95% CI, -8.5 to -6.7]), and Self-rating Anxiety Scale (-2.9 [95% CI, -4.1 to -1.7]) scores and the total sleep time recorded in the actigraphy (29.1 [95% CI, 21.5-36.7] minutes) was observed in the EA group during the 8-week intervention period (P < .001 for all). No between-group differences were found in the frequency of sleep awakenings. No serious adverse events were reported.

CONCLUSIONS AND RELEVANCE: In this randomized clinical trial of EA treatment for insomnia in patients with depression, quality of sleep improved significantly in the EA group compared with the SA or control group at week 8 and was sustained at week 32.

ABSTRACT

IMPORTANCE: Recent studies suggest that theophylline added to saline nasal irrigation (SNI) can be an effective treatment for postviral olfactory dysfunction (OD), a growing public health concern during the COVID-19 pandemic.

OBJECTIVE: To evaluate the efficacy and safety of theophylline added to SNI compared with placebo for COVID-19-related OD.

DESIGN, SETTING, AND PARTICIPANTS: This triple-blinded, placebo-controlled, phase 2 randomized clinical trial was conducted virtually between March 15 and August 31, 2021. Adults residing in Missouri or Illinois were recruited during this time period if they had OD persisting for 3 to 12 months following suspected COVID-19 infection. Data analysis was conducted from October to December 2021.

INTERVENTIONS: Saline sinus rinse kits and bottles of identical-appearing capsules with either 400 mg of theophylline (treatment) or 500 mg of lactose powder (control) were mailed to consenting study participants. Participants were instructed to dissolve the capsule contents into the saline rinse and use the solution to irrigate their nasal cavities in the morning and at night for 6 weeks.

MAIN OUTCOMES AND MEASURES: The primary outcome was the difference in the rate of responders between the treatment and the control arms, defined as a response of at least slightly better improvement in the Clinical Global Impression-Improvement scale posttreatment. Secondary outcome measures included changes in the University of Pennsylvania Smell Identification Test (UPSIT), the Questionnaire for Olfactory Disorders, the 36-Item Short Form Health Survey on general health, and COVID-19-related questions.

RESULTS: A total of 51 participants were enrolled in the study; the mean (SD) age was 46.0 (13.1) years, and 36 (71%) participants were women. Participants were randomized to SNI with theophylline (n = 26) or to SNI with placebo (n = 25). Forty-five participants completed the study. At the end of treatment, 13 (59%) participants in the theophylline arm reported at least slight improvement in the Clinical Global Impression-Improvement scale (responders) compared with 10 (43%) in the placebo arm (absolute difference, 15.6%; 95% CI, -13.2% to 44.5%). The median difference for the UPSIT change between baseline and 6 weeks was 3.0 (95% CI, -1.0 to 7.0) for participants in the theophylline arm and 0.0 (95% CI, -2.0 to 6.0) for participants in the placebo arm. Mixed-model analysis revealed that the change in UPSIT scores through study assessments was not statistically significantly different between the 2 study arms. Eleven (50%) participants in the theophylline arm and 6 (26%) in the placebo arm had a change of 4 or more points in UPSIT scores from baseline to 6 weeks. The difference in the rate of responders as measured by the UPSIT was 24% (95% CI, -4% to 52%) in favor of theophylline.

CONCLUSIONS AND RELEVANCE: This randomized clinical trial suggests that the clinical benefit of theophylline nasal irrigations on olfaction in participants with COVID-19-related OD is inconclusive, though suggested by subjective assessments. Larger studies are warranted to investigate the efficacy of this treatment more fully.

ABSTRACT

INTRODUCTION: There is a paucity of literature on the efficacy and safety of ultrafiltration in Chinese patients with heart failure (HF). Therefore, we aimed to compare the efficacy and safety of ultrafiltration with diuretics and provide information and evidence as to the best approach for patients with HF.

METHODS: In this single-center, non-randomized interventional study patients with HF either received diuretics or ultrafiltration. The efficacy outcomes included changes in the weight, dyspnea score, and 6-min walk distance from baseline to 48 h after treatment. Safety outcomes were evaluated in both the groups with respect to changes in systolic blood pressure, heart rate, serum creatinine, blood urea nitrogen, blood potassium ion concentration, and blood sodium ion concentration.

RESULTS: A total of 149 patients with HF (diuretics, 73; ultrafiltration, 76) were included. At 48 h, patients in the ultrafiltration group showed significantly greater weight loss and better improvement in dyspnea score and 6-min walk distance compared to patients in the control group (P < 0.05). However, the two groups showed no statistically significant difference in terms of safety outcomes such as systolic blood pressure, heart rate, serum creatinine, blood urea nitrogen, blood potassium ion concentration, and blood sodium ion concentration, suggesting similar safety profiles of both the groups.

CONCLUSION: Ultrafiltration was associated with greater weight loss and better dyspnea score and 6-min walk distance with similar safety profiles as compared with diuretics. Ultrafiltration can be considered as an optimal option for Chinese patients with HF.

ABSTRACT

PURPOSE: To estimate the association between changes in BMI and changes in Health-Related Quality of Life (EQ-5D-3L).

METHODS: The WRAP trial was a multicentre, randomised controlled trial with parallel design and recruited 1267 adults (BMI ≥ 28 kg/m²). Participants were allocated to Brief Intervention, a Commercial weight management Programme (WW, formerly Weight Watchers) for 12 weeks, or the same Programme for 52 weeks. Participants were assessed at 0, 3, 12, 24, and 60 months. We analysed the relationship between BMI and EQ-5D-3L, adjusting for age and comorbidities, using a fixed effects model. Test for attrition, model specification and missing data were conducted. Secondary analyses investigated a non-symmetric gradient for weight loss vs. regain.

RESULTS: A unit increase in BMI was associated with a – 0.011 (95% CI – 0.01546, – 0.00877) change in EQ-5D-3L. A unit change in BMI between periods of observation was associated with – 0.016 017 (95% CI – 0.0077009, – 0.025086) change in EQ-5D-3L. The negative association was reduced during weight loss, as opposed to weight gain, but the difference was not statistically significant.

CONCLUSIONS: We have identified a strong and statistically significant negative relationship between BMI changes and HRQoL. These estimates could be used in economic evaluations of weight loss interventions to inform policymaking.

CLINICAL TRIAL REGISTRATION: This trial was registered with Current Controlled Trials, number ISRCTN82857232.

ABSTRACT

INTRODUCTION: Aerobic exercise training after stroke has positive effects on quality of life, motor recovery, and aerobic endurance. The aim of this study was to investigate the effectiveness of anti-gravity treadmill gait training and underwater walking therapy on cardiorespiratory fitness, gait and balance in stroke survivors.

METHODS: The study included 39 patients with a history of stroke who were admitted to our center between July 2017 and January 2018. The patients were randomly assigned to anti-gravity treadmill training, underwater walking therapy, or a control group. The aerobic capacity of the participants was evaluated with the 6-min walk test and cycle ergometer testing before and after the treatment. Balance was examined using the Berg Balance Scale (BBS).

RESULTS: There was a statistically significant increase from pre- to post-treatment with regard to maximum heart rate and length of walking distance during 6-min walk test parameters in patients who underwent anti-gravity treadmill training (p < 0.05). The cycle ergometer training results showed significant improvements compared to baseline after treatment in patients who underwent anti-gravity training in terms of maximum heart rate attained during exercise stress testing, time to complete the test, rates of metabolic equivalents of task scores and peak oxygen consumption (p < 0.05). Improvements were also observed in ventricular repolarization indices including corrected QT intervals (QTc), Tp-e interval and Tp-e/QT, Tp-e/QTc ratio in the anti-gravity group (p < 0.05). BBS results showed no statistically significant difference in all groups (p > 0.05).

CONCLUSION: The data of this study showed that anti-gravity treadmill training has favorable effects on cardiorespiratory fitness in stroke survivors.

ABSTRACT

BACKGROUND: Fatigue is a common and often debilitating symptom experienced by many stroke survivors. Significant post stroke fatigue may predispose individuals to other health complications, such as falls, which can lead to fractures and soft tissue injuries. Only limited research has examined the association between fatigue and falls in stroke survivors.

METHODS: Data were obtained from the Sax Institute’s 45 and Up Study, from a subset of individuals who had experienced a stroke. The Modified Fatigue Impact Scale-5-item version (MFIS-5) was used to measure the level of fatigue. A logistic regression model, adjusted for stroke characteristics and comorbidities, was used to determine the magnitude of association between change in fatigue score and odds of having had a fall.

RESULTS: A total of 576 participants completed the questionnaire. A total of 214 (37.2%) participants reported having had a fall in the previous 12 months. There was a statistically significant association between fatigue scores and fall status (p < 0.001). Specifically, for every 1-point increase in the fatigue score (MFIS-5) (i.e. higher level of fatigue), the odds of a person having a fall is 1.10 times greater (AOR = 1.10; 95% CI 1.05, 1.15; p < 0.001).

CONCLUSION: This study revealed an association between an increasing risk of falls with increasing severity of post stroke fatigue. Accurate detection and management of fatigue may help reduce the risk of falls and should be the focus of future research.

ABSTRACT

Phase separation is one of the fundamental processes to compartmentalize biomolecules in living cells. RNA-protein complexes (RNPs) often scaffold biomolecular condensates formed through phase separation. We here present a statistical thermodynamics approach to investigate intracellular phase separation. We first present the statistical thermodynamic theory of the liquid-liquid phase separation (LLPS) of two molecules (such as proteins and solvent molecules) and of a polymer solution (such as RNPs and solvent molecules). Condensates produced by LLPS show coarsening and/or coalescence to minimize their total surface area. In addition to the LLPS, there are other types of self-assembly, such as microphase separation, micellization, emulsification, and vesiculation, with which the growth of the assembly stops with optimal size and shape. We also describe a scaling theory of micelles of block copolymers, where their structures are analogous to the core-shell structure of paraspeckle nuclear bodies scaffolded by RNPs of NEAT1_2 long noncoding RNAs (lncRNAs) and RNA-binding proteins (RBPs). These theories treat the self-assembly of polymers in the thermodynamic equilibrium, where their concentrations and compositions do not change with time. In contrast, RNPs are produced according to the transcription of RNAs and are degraded with time. We therefore take into account the dynamical aspect of the production of RNPs in an extension of the theory of the self-assembly of soft matter. Finally, we discuss the structure of paraspeckles as an example to demonstrate that an approach combining experiment and theory is powerful to investigate the mechanism of intracellular phase separation.
