Feasibility and acceptability of general practitioners using sit-stand desks: a feasibility trial.

OBJECTIVES: The primary aim of this study was to investigate the feasibility and acceptability of general practitioners (GPs) using sit-stand desks to facilitate standing during consultations. A further aim was to examine the views of patients about GPs standing for their consultations. DESIGN: A pre-post single-group experimental trial design. SETTING: General practices in England, UK. PARTICIPANTS: 42 GPs (working a minimum of five clinical sessions per week) and 301 patients (aged ≥18 years). INTERVENTIONS: The intervention consisted of each GP having a sit-stand desk (Opløft Sit-Stand Platform) installed in their consultation room for 4 working weeks. Sit-stand desks allow users to switch, in a few seconds, between a sitting and standing position and vice versa, by adjusting the height of the desk. MAIN OUTCOME MEASURES: To test feasibility and acceptability, GPs reported their views about using sit-stand desks at work at baseline and follow-up. Sitting time and physical activity were also measured via accelerometer at baseline and follow-up. Patients who attended a consultation where their GP was standing were asked to complete an exit questionnaire about the perceived impact on the consultation. RESULTS: Most GPs reported using their sit-stand desk daily (n=28, 75.7%). 16 GPs (44.4%) used their sit-stand desk during face-to-face consultations every day. Most GPs and patients did not view that GPs standing during face-to-face consultations impacted the doctor-patient relationship (GPs; 73.5%, patients; 83.7%). GPs' sitting time during work was 121 min per day lower (95% CI: -165 to -77.58) at follow-up compared with baseline. CONCLUSIONS: Use of sit-stand desks is acceptable within general practice and may reduce sitting time in GPs. This may benefit GPs and help reduce sitting time in patients.

Growable design of passenger vehicle interior space based on FAHP and FQFD.

The increasingly shortened development cycle of smart vehicles has led to a qualitative shift in the nature of automotive products. Growing spatial design of vehicle interiors can effectively satisfy users' personalisation preferences and increase their willingness to buy, as well as mitigating the environmental pollution caused by the problem of rapid replacement. Considering the subjectivity and uncertainty of users' emotional needs, this study adopts the FAHP method to comprehensively analyse and rank the SET series of factors, then combines the grey correlation method with the correlation analysis of the areas related to the interior space of the automobile, constructs the sample of the interior space of the automobile and extracts the kansei words of the space sample. Intentional vocabulary mean scores were calculated to factor analyses through kansei engineering, next the fuzzy QFD quality house was built to make affective semantic design associations and derive design weights, which are then used to guide the design and ultimately realise the design of a dynamic automotive interaction scenario. The results of the study show that the integration of different theories can reduce the uncertainties in accessing users' emotional needs. At the same time, it can provide systematic guidance for the interaction design of a growable automobile in terms of multiple dimensions of interior space connectivity, spatial layout, and perceptual experience, as well as provide valuable suggestions for the subsequent development of interior spaces.

An evaluation model for interactive gaming furniture design based on parent-child behavior.

This study takes the parent-child game behavior of children aged 3~6 and their parents as the research object, and extracts and summarizes the user behavioral needs of parents and children when they use game-based furniture together by using the questionnaire research method, observation method, and interview method. Based on the KJ method, 16 behavioral demand indicators were compiled by five furniture design students to construct a user behavioral demand system. In addition, AHP and entropy weight method were used to solve the user behavioral demand weights from subjective and objective perspectives in this study. Twenty experts and designers in this research field scored the indicators two by two and solved the subjective weights of user behavioral requirements according to the AHP algorithm. A seven-level Likert scale was used to design the questionnaire and distribute it to the parents of children aged 3-6 to fill in, and the 121 valid questionnaires obtained were used as raw data for entropy weighting to obtain the objective weights of user behavioral needs representing the opinions of interactive game-based furniture users. Finally, with 0.4 as the proportion coefficient of subjective weights, the subjective and objective weights were weighted to get the comprehensive weight value of each demand. The results show that the eight items with higher weights for user behavioral needs include: firm and stable, safe in use, comfortable for both parents and children, holding behavior by human-machine dimensions, able to sit on the ground and play, able to play face-to-face, easy to find for picking up, and sufficient operating space. In general, parent-child interactive game furniture firstly needs to meet the user's needs for safety and comfort, and secondly needs to meet the user's needs for the state of the game posture and the furniture size to meet the needs of the fetching and storage posture and the game space. The fuzzy comprehensive evaluation model established based on these needs can take into account the opinions of design experts and users at the same time and put the needs of children and parents in an equally important position so that the design of children's play furniture can tend to meet the needs of parents and children when they use it together, and to promote parent-child interaction and the healthy growth of children.

Active workstations: A literature review on workplace sitting.

The purpose of this paper is to further understand current literature on prolonged sitting, sitting posture and active sitting solutions. This paper is divided into three sections: The first section (Part I) is a comprehensive overview of the literature on how a static prolonged seated posture can affect: spinal health, trunk posture, contact pressure/discomfort development and vascular issues. The second section (Part II) reviews and qualitatively compares the four working postures recognized in ANSI/HFES 100-2007: reclined sitting, upright sitting, declined sitting and standing. The final section (Part III) is a summary of research on active chairs that revolves around the two types of movement patterns: 1- sustaining continual movement over a range of postures, occasionally reaching neutral lordosis, and 2- maintaining high frequency and duration of daily light contractile activity in the legs (or lower limbs).

Earthquake in Turkey: The Triangle of Life and Disaster Kits Saves Lives.

OBJECTIVE: Precautions taken before an earthquake are of vital importance. When buildings collapse, the weight of the ceiling crushes objects such as furniture, leaving a space or void within the rubble. This area is called the "triangle of life." The larger and stronger the object, the more it will maintain its volume; the more the object maintains its volume, the larger the void will be, and the less likely it is that the person who uses this void will be injured. METHODS: Durable, solid furniture such as beds and tables that can be tipped over during an earthquake in appropriate areas in the building can form a living triangle. Creating and using the triangle of life is the method of protection in an earthquake that produces the highest probability of survival. RESULTS: Two earthquakes with magnitudes of 7.8 and 7.5 occurred in Kahramanmaras, Turkey, on February 6, 2023. This report presents the case of a 43-y-old female victim of these earthquakes who used the triangle of life to survive; she was removed from the rubble 164 h after the earthquake. CONCLUSIONS: The case provides evidence that predetermining areas in which the triangle of life can be formed and storing supplies necessary for survival can decrease morbidity and mortality in an earthquake.

Spatial experience of cancer inpatients in the oncology wards: A qualitative study in visual design aspects.

PURPOSE: This paper aims to explore how the visual characteristics of cancer wards' interior spaces can be improved based on the combined visual design themes to help cancer inpatients' spatial experience and relieved state of mind. Accordingly, we present a visual design framework that can be applied in oncology wards. METHOD: This study adopts the Ulrich-supportive design theory as a theoretical framework using two main methodological phases: observation of cancer wards and interviews with professional caregivers. The first phase critically explores hospital cancer wards' interactive aesthetical and visual interior characteristics. Next, we adjusted the visual criteria based on the Post Occupation Evaluation (POE) method to develop the interview questions. Interviews were conducted with experienced nurses, oncologists, and a general physician, all from a cancer ward at McGill University Health Center (MUHC) in Montreal, Canada. RESULTS: We presented 11 main themes in the categories of color and light, natural/artistic images, way-finding, and visual clutter. To present and justify our visual design framework, these main themes were then classified based on the common goals, resulting in four combined themes: applying simplicity and usability; developing naturality; creating homeyness and respecting patients' agency; and promoting trustworthiness. CONCLUSION: Our findings suggest that-apart from the last theme, promoting trustworthiness, the rest are in line with Ulrich's supportive design theory. Therefore, further research is needed to investigate "promoting trustworthiness" in the context of cancer wards. In addition, each aspect of the visual design framework can offer practical design recommendations for future studies.

Electric massage chairs reduce labor pain in nulliparous patients: a randomized crossover trial.

BACKGROUND: Labor pain varies significantly among pregnant women, ranging from mild to extremely distressing. Nonpharmacologic pain relief methods during vaginal birth are increasingly popular, either as a complement to pharmacologic agents or, at times, as the primary method of pain relief. Multiple trials have reported that manual or by-hand massage reduces labor pain. The effectiveness of full-body mechanical massage using electric massage chairs on labor pain remains unexplored. OBJECTIVE: This study aimed to evaluate mechanical massage using an electric massage chair on labor pain in nulliparous women. STUDY DESIGN: A randomized counterbalanced crossover trial was conducted in a university hospital in Malaysia from August 2022 to February 2023. Eligible nulliparas in labor with a minimum labor pain score of 5 (0-10 numerical rating scale) were enrolled. Participants were randomized to 30 minutes on the massage chair with mechanical massage followed by 30 minutes on the massage chair without mechanical massage or the other way around in the massage sequence. The primary outcome was a change in pain score comparing pain with and without mechanical massage as a paired comparison for the entire trial participants. The secondary outcomes were across arms analyses of maternal and neonatal outcomes. The paired t test, t test, Mann-Whitney U test, chi-square test, and Fisher exact test were used as appropriate for the data. RESULTS: Overall, 208 women were randomized: 104 to each intervention. Data were available from 204 participants (103 randomized to massage first and 101 to no massage first). The primary outcomes of change in labor pain scores (0-10 numerical rating scale) after massage and no massage (all participants included after crossover, paired t test analysis) were 4.51±2.30 and 5.38±2.10, respectively (mean difference, -0.87; 95% confidence interval, -1.14 to -0.59; P<.001), a significant reduction in pain score after electric chair mechanical massage compared with no massage. On the across randomized arms secondary analyses, labor pain scores after their first massage chair session were 4.35±2.52 (randomized to massage first, received massage as initial intervention) and 5.66±1.73 (randomized to no massage first, received no massage as initial intervention) (mean difference, -1.31; 95% confidence interval, -1.91 to -0.748; P<.001), a significant reduction after mechanical massage. Other distal maternal outcomes (mode of delivery, labor analgesia, duration of labor, and maternal agreement that mechanical massage is effective for labor pain) and neonatal outcomes (Apgar scores at 1 and 5 minutes, cord artery blood pH and base excess, and neonatal admission) were not different across randomized arms. CONCLUSION: Mechanical massage using an electric massage chair significantly reduced labor pain, offering a potential nonpharmacologic pain management option during labor.

An online survey capturing the views of stakeholders on primary school food systems across the four UK nations.

BACKGROUND: In 2020, the Generating Excellent Nutrition in UK Schools (GENIUS) Network was established to develop an understanding of the school food system across the four UK nations. This study explores stakeholders' views (headteachers, teachers, parents and pupils) on what works well, the challenges, and what an ideal primary school food system includes. METHODS: An online 'School Food Survey' was created in Qualtrics XM including closed and open-ended questions about the primary school food system. The Qualtrics link was distributed to stakeholders with an interest in school food through key contacts and networks across the four UK nations (21st June to 21st July and September 2021). Responses from the open-ended questions were exported from Qualtrics into Excel and analysed using SPSS. Aspects of qualitative content analysis were applied to summarise, code and quantify responses. Identified codes were entered by stakeholder, for example, parents and their response to the question into a Matrix table to allow identification of categories, themes and interpretation. RESULTS: A total of 509 participants completed the survey: most participants were from Scotland (n = 281; 55%) and England (n = 213; 42%) and were parents (n = 394). There were some consistent views across stakeholder responses, for example, the range of healthy options, costs, and portion sizes offered to pupils. Parents views varied, with some expressing the range of healthy options worked well and others reporting too many unhealthy choices. The cost of school food and school food funding presented challenges for both parents and schools. For parents, an ideal school food system would include a wide variety of fresh healthy food choices that were made on site, use quality produce, be inclusive for all cultures and diets, and provide food portion sizes appropriate for pupils ages. CONCLUSIONS: The findings iterate the diversity and some inconsistencies between stakeholders, emphasising the complexity and competing tensions school food systems encounter. Parental involvement and consideration of school-level and national factors are important when identifying challenges, what works well and describing an ideal primary school food system.

Underwater image enhancement using Divide-and-Conquer network.

Underwater image enhancement has become the requirement for more people to have a better visual experience or to extract information. However, underwater images often suffer from the mixture of color distortion and blurred quality degradation due to the external environment (light attenuation, background noise and the type of water). To solve the above problem, we design a Divide-and-Conquer network (DC-net) for enhancing underwater image, which mainly consists of a texture network, a color network and a refinement network. Specifically, the multi-axis attention block is presented in the texture network, which combine different region/channel features into a single stream structure. And the color network employs an adaptive 3D look-up table method to obtain the color enhanced results. Meanwhile, the refinement network is presented to focus on image features of ground truth. Compared to state-of-the-art (SOTA) underwater image enhance methods, our proposed method can obtain the better visual quality of underwater images and better qualitative and quantitative performance. The code is publicly available at https://github.com/zhengshijian1993/DC-Net.

Assessment of differentially private synthetic data for utility and fairness in end-to-end machine learning pipelines for tabular data.

Differentially private (DP) synthetic datasets are a solution for sharing data while preserving the privacy of individual data providers. Understanding the effects of utilizing DP synthetic data in end-to-end machine learning pipelines impacts areas such as health care and humanitarian action, where data is scarce and regulated by restrictive privacy laws. In this work, we investigate the extent to which synthetic data can replace real, tabular data in machine learning pipelines and identify the most effective synthetic data generation techniques for training and evaluating machine learning models. We systematically investigate the impacts of differentially private synthetic data on downstream classification tasks from the point of view of utility as well as fairness. Our analysis is comprehensive and includes representatives of the two main types of synthetic data generation algorithms: marginal-based and GAN-based. To the best of our knowledge, our work is the first that: (i) proposes a training and evaluation framework that does not assume that real data is available for testing the utility and fairness of machine learning models trained on synthetic data; (ii) presents the most extensive analysis of synthetic dataset generation algorithms in terms of utility and fairness when used for training machine learning models; and (iii) encompasses several different definitions of fairness. Our findings demonstrate that marginal-based synthetic data generators surpass GAN-based ones regarding model training utility for tabular data. Indeed, we show that models trained using data generated by marginal-based algorithms can exhibit similar utility to models trained using real data. Our analysis also reveals that the marginal-based synthetic data generated using AIM and MWEM PGM algorithms can train models that simultaneously achieve utility and fairness characteristics close to those obtained by models trained with real data.

Exploring Convolutional Neural Network Architectures for EEG Feature Extraction.

The main purpose of this paper is to provide information on how to create a convolutional neural network (CNN) for extracting features from EEG signals. Our task was to understand the primary aspects of creating and fine-tuning CNNs for various application scenarios. We considered the characteristics of EEG signals, coupled with an exploration of various signal processing and data preparation techniques. These techniques include noise reduction, filtering, encoding, decoding, and dimension reduction, among others. In addition, we conduct an in-depth analysis of well-known CNN architectures, categorizing them into four distinct groups: standard implementation, recurrent convolutional, decoder architecture, and combined architecture. This paper further offers a comprehensive evaluation of these architectures, covering accuracy metrics, hyperparameters, and an appendix that contains a table outlining the parameters of commonly used CNN architectures for feature extraction from EEG signals.

Gas concentration mapping and source localization for environmental monitoring through unmanned aerial systems using model-free reinforcement learning agents.

There are three primary objectives of this work; first: to establish a gas concentration map; second: to estimate the point of emission of the gas; and third: to generate a path from any location to the point of emission for UAVs or UGVs. A mountable array of MOX sensors was developed so that the angles and distances among the sensors, alongside sensors data, were utilized to identify the influx of gas plumes. Gas dispersion experiments under indoor conditions were conducted to train machine learning algorithms to collect data at numerous locations and angles. Taguchi's orthogonal arrays for experiment design were used to identify the gas dispersion locations. For the second objective, the data collected after pre-processing was used to train an off-policy, model-free reinforcement learning agent with a Q-learning policy. After finishing the training from the training data set, Q-learning produces a table called the Q-table. The Q-table contains state-action pairs that generate an autonomous path from any point to the source from the testing dataset. The entire process is carried out in an obstacle-free environment, and the whole scheme is designed to be conducted in three modes: search, track, and localize. The hyperparameter combinations of the RL agent were evaluated through trial-and-error technique and it was found that ε = 0.9, γ = 0.9 and α = 0.9 was the fastest path generating combination that took 1258.88 seconds for training and 6.2 milliseconds for path generation. Out of 31 unseen scenarios, the trained RL agent generated successful paths for all the 31 scenarios, however, the UAV was able to reach successfully on the gas source in 23 scenarios, producing a success rate of 74.19%. The results paved the way for using reinforcement learning techniques to be used as autonomous path generation of unmanned systems alongside the need to explore and improve the accuracy of the reported results as future works.

Wall-mounted folding chairs to promote resident physician sitting at the hospital bedside.

BACKGROUND: Sitting at the bedside may improve patient-clinician communication; however, many clinicians do not regularly sit during inpatient encounters. OBJECTIVE: To determine the impact of adding wall-mounted folding chairs inside patient rooms, beyond any impact from a resident education campaign, on the patient-reported frequency of sitting at the bedside by internal medicine resident physicians. DESIGN, SETTING, AND PARTICIPANTS: Prospective, controlled pre-post trial between 2019 and 2022 (data collection paused 2020-2021 due to COVID-19) at an academic hospital in Baltimore, Maryland. Folding chairs were installed in two of four internal medicine units and educational activities were delivered equally across all units. MAIN OUTCOME AND MEASURES: Patient-reported frequency of sitting at bedside, assessed as means on Likert-type items with 1 being "never" and 5 being "every single time." We also examined the frequency of other patient-reported communication behaviors. RESULTS: Two hundred fifty six and 206 patients enrolled in the pre and post-intervention periods, respectively. The mean frequency of patient-reported sitting by resident physicians increased from 1.8 (SD 1.2) to 2.3 (1.2) on education-only units (absolute difference 0.48 [95% CI: 0.21-0.75]) and from 2.0 (1.3) to 3.2 (1.4) on units receiving chairs (1.16, [0.87-1.45]). Comparing differences between groups using ordered logistic regression adjusting for clustering within residents, units with added chairs had greater increases in sitting (odds ratio 2.05 [1.10-3.82]), spending enough time at the bedside (2.43 [1.32-4.49]), and checking for understanding (3.04 [1.44-6.39]). Improvements in sitting and other behaviors were sustained on both types of units. CONCLUSIONS: Adding wall-mounted folding chairs may help promote effective patient-clinician communication.

Tabular, Annotated, Visual, or Trends + Contextual Information? Preferences for Online Laboratory Results Displays.

People are increasingly offered access to their personal health information (e.g., laboratory results, clinical notes, diagnostic imaging results). However, this information is the same as that used by health care providers with clinical expertise and training in medical terminology, which citizens typically do not have. In this study, we examined participants (N = 24) preferences for four different types of displays for online laboratory (lab) results: Tabular, Annotated, Visual, and Trends + Contextual Information. The Friedman test of difference comparing participants' ratings of the four displays was significant, χ2(3)=10.8, P=.013, and the Wilcoxon signed rank pairwise comparison tests revealed that participants rated the visual lab results display significantly more favourably than the traditional display (Z=-2.746, P=.006). These findings indicate that many people prefer lab results displayed using more visual cues and some perceived this format as easier to understand than the other display formats. Given the importance of people accessing, understanding, and using their own health information, it is crucial for displays and systems to provide a better user experience. Displaying data (e.g., lab results) visually is one possible way to improve interpretability of personal health information provided to the public.

Simulation analysis of hazardous chemicals released from the furniture plant using ALOHA software.

The manufacturing of wooden furniture is extensive in Thailand's east. Hazardous chemicals were used in the wooden furniture industry's manufacturing process. Hazardous substances released into the surrounding atmosphere appear to have an impact on the environment and individuals. The ALOHA model is frequently used to assess hazardous chemicals released into the environment; this simulation model is an effective tool for modeling chemical compounds and detecting chemical disasters. It has a tremendous potential for preventing mishaps in potentially hazardous or emergency situations. Acetone and butyl acetate were extracted from the hardwood furniture business to identify accidents such as leaking, spillage, and evaporation. It is described as a highly poisonous, combustible, and explosive material. Toxic accident releases have negative implications for the surrounding areas. The goal of this work was to examine each accident using ALOHA software, and the computation of acetone and butyl acetate accidents was shown in this study. This project provides critical data for the furniture plant's chemical emergency rescue strategy as well as recommendations for emergency evacuation site decision-making.

Trends in flame retardant levels in upholstered furniture and children's consumer products after regulatory action in California.

In 2013, California revised its upholstered furniture flammability standard TB 117-2013 to improve fire safety without the need for flame retardant (FR) chemicals. Subsequent legislation (SB 1019) required disclosure of FR content. In 2020 California expanded restriction on FR chemicals to include juvenile products and upholstered furniture (AB 2998). To monitor trends in FR use, and assess the effectiveness of the new regulations, we analyzed 346 samples from upholstered furniture (n = 270) and children's consumer products (n = 76), collected pre- and post-regulatory intervention for added FR chemicals (i.e., ∑FR > 1000 mg/kg). Upholstered furniture samples, collected from products before enactment of the new regulations, had a median FR concentration of 41,600 mg/kg (range: 1360-92,900 mg/kg), with 100% of the foam samples and 13.7% of the textile samples containing ∑FR > 1000 mg/kg. Firemaster formulations (FM 550 and FM 600), a mixture of triphenyl phosphate (TPHP), 2-ethylhexyl-2,3,4,5-tetrabromobenzoate (EH-TBB), bis(2-ethylhexyl)-3,4,5,6-tetrabromophthalate (BEH-TEBP) and a mixture of isopropyl- or tert-butyl-triphenyl phosphates (ITPs or TBPPs), were the most frequently detected FR (34%), followed by tris(1,3-dichloroisopropyl) phosphate (TDCIPP; 25%), TPHP with a mixture of polybrominated diphenyl ethers (BDE-47, 99, 100, 153 and 154; 20%) and tris(2-chloroethyl) phosphate (TCEP; 11%). Upholstered furniture components collected after enactment of the new legislation had a median FR concentration of 2600 mg/kg (range: 1160-49,800 mg/kg, outlier sample 282,200 mg/kg), with 11.9% of the foam samples and no textile samples containing ∑FR > 1000 mg/kg. Of these samples, tris(1-chloro-2-propyl) phosphate (TCIPP) was the most frequently detected FR (55%), followed by TDCIPP (30%) and Firemaster (FM 550, 15%). No PBDEs were detected in the post-regulatory intervention products. Our initial work on children's products showed 15% of the samples contained ∑FR > 1000 mg/kg. In our post- AB 2998 work, no regulated children's product components failed compliance (i.e., ∑FR > 1000 mg/kg). The data confirm successful adoption of the new regulations with most samples in compliance, demonstrating the efficacy of regulatory intervention. Given these results, environmental FR exposure is expected to decrease as older FR treated consumer products are replaced with FR free products.

Health and Safety Executive research on wood dust exposure controls in British manufacturing.

To generate new intelligence on occupational exposure to wood dust in woodworking manufacturing activities in Britain, the Health and Safety Executive (HSE) performed 22 occupational hygiene site visits to assess exposure and exposure controls between 2014 and 2017. The work aimed to characterise good practice and therefore sites with a poor health and safety record, as identified from HSE inspection records, were not invited to participate. Sites selected covered furniture production, joinery, saw milling, and boat building and repair. Twenty-three follow-up telephone interviews were also carried out across 15 of the companies with supervisors and managers to explore how they tried to promote good practice among the workforce, and if there are any potential challenges encountered. The aim of the interviews was to gain a better understanding of how to enable organisations to improve the management of wood dust exposure. This study found that 6.0% of all wood dust exposure measurements (15 out of 252) were above 5 mg/m³, and 17.6% of exposures to hardwood dust or mixtures of hardwood and softwood dust (38 out of 216) were above 3 mg/m³ (the then current and future workplace exposure limits). Sanding, cleaning, and maintenance activities were of particular concern. Improvements to exposure controls are required, in particular, improvements to local exhaust ventilation controls for hand-held power tools and hand sanding. The management, selection, and use of respiratory protective equipment were poor. All the managers and supervisors recognised that exposure to wood dust can pose serious health risks, and that controls were crucial to protecting workers' health. The findings from the telephone interviews suggest that supervision and provision of information about the health effects of exposure to wood dust were common approaches that organisations used to raise awareness and promote good practice, in relation to managing wood dust exposure. Worker attitudes towards controls, such as perceptions that they hinder task completion and habitual ways of working, were identified as factors influencing the use of controls. Risk communication approaches that focus on increasing workers' awareness of their susceptibility to ill-health using credible sources, such as peers, can help enhance the uptake of messages on the use of controls. Financial constraints were identified as a challenge to improving the control of wood dust, particularly for small companies.

Design of Pediatric Outpatient Procedure Environments: A Pilot Study to Understand the Perceptions of Patients and Their Parents.

OBJECTIVE: To understand parent and child perception of spaces experienced during outpatient procedures and to measure their anxiety in these spaces. BACKGROUND: Same-day procedures are becoming prevalent among children in the United States. While studies conducted in different types of healthcare settings show that the physical environment influences healthcare experiences of patients, there is a lack of research on patient and family perceptions of the physical environment of the outpatient centers where such procedures are conducted. METHODS: This study used ecological momentary assessment to collect patient experience and anxiety data at different points during the patient's journey through an ambulatory surgical center where pediatric gastrointestinal (GI) procedures were performed. Objective and subjective measures of anxiety were collected. A Qualtrics survey asked participants' perceptions about four spaces-waiting, preprocedure, procedure, and recovery. RESULTS: Child participants reported liking murals, double chairs, patient beds, wall color, and access to a television. They disliked medical equipment and lack of child-friendly furniture. Most parents liked the murals, access to a television, and nature photos, while disliking the lack of privacy, lack of toys in waiting areas, and lack of child-friendly furniture. On average, both children and parents experienced the highest anxiety levels before and during the procedure and the lowest during recovery. Between the four spaces, no significant differences were observed in the heart rate variability and skin conductance responses for both groups. CONCLUSIONS: Despite the outpatient nature of the procedures, participants experienced anxiety before the GI procedure. Comfortable design features that provide distractions are preferred by children and their parents.

Reimagine the ICU: Healthcare Professionals' Perspectives on How Environments (Can) Promote Patient Well-Being.

OBJECTIVE: This study aims (1) to understand the needs and challenges of the current intensive care unit (ICU) environments in supporting patient well-being from the perspective of healthcare professionals (HCPs) and (2) to explore the new potential of ICU environments enabled by technology. BACKGROUND: Evidence-based design has yielded how the design of environments can advocate for patient well-being, and digital technology offers new possibilities for indoor environments. However, the role of technology in facilitating ICU patient well-being has been unexplored. METHOD: This study was conducted in two phases. First, a mixed-method study was conducted with ICU HCPs from four Dutch hospitals. The study investigated the current environmental support for care activities, as well as the factors that positively and negatively contribute to patient experience. Next, a co-creation session was held involving HCPs and health technology experts to explore opportunities for technology to support ICU patient well-being. RESULTS: The mixed-method study revealed nine negative and eight positive patient experience factors. HCPs perceived patient emotional care as most challenging due to the ICU workload and a lack of environmental support in fulfilling patient emotional needs. The co-creation session yielded nine technology-enabled solutions to address identified challenges. Finally, drawing from insights from both studies, four strategies were introduced that guide toward creating technology to provide holistic and personalized care for patients. CONCLUSION: Patient experience factors are intertwined, necessitating a multifactorial approach to support patient well-being. Viewing the ICU environment as a holistic unit, our findings provide guidance on creating healing environments using technology.
