Toward Healthy Underground Spaces: A Review of Underground Environmental Design Factors and Their Impacts on Users' Physiological and Psychological Health.

OBJECTIVE: This study aims to review and synthesize what design factors are associated with the physiological and psychological health of occupants in underground spaces. BACKGROUND: The development of underground spaces offers options to global challenges, such as traffic congestion, urban overcrowding, the revitalization of dormant underground areas, disaster mitigation, and adaptation to extreme environments. Despite these advantages, concerns persist about potential adverse effects on human health in these environments. This situation underlines the necessity of systematically identifying concerns and perceptions related to health in underground spaces. METHODS: A narrative literature review was conducted to examine the relationship between design factors and health factors across 21 empirical studies. Based on the review of the identified literature, a relationship diagram was developed to depict the interconnections between the identified design and health factors. RESULTS: The analysis identified design factors related to the air, sound, light, nature, transport, and spatial context of underground spaces, each of which exerted relationships with occupants' physiological and psychological health factors. The relationship diagram indicated that the psychological factor "feeling of confinement" was mentioned most frequently, suggesting that it is one of the most extensively researched factors in this context. CONCLUSIONS: The relationship diagram aims to bridge the existing knowledge gap and set the stage for future research endeavors. The ultimate goal is to refine urban living standards by leveraging the potential of underground spaces while ensuring health and well-being.

Historical evolution of healthcare systems of post-soviet Russia, Belarus, Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, Uzbekistan, Armenia, and Azerbaijan: A scoping review.

This scoping review addresses the transformation and development of new healthcare systems in nine countries -Armenia, Azerbaijan, Belarus, Kazakhstan, Kyrgyzstan, Russia, Tajikistan, Turkmenistan, and Uzbekistan over the period following the collapse of the Soviet Union from 1991 to the present. This assessment focuses on maternal and child health, mental health, communicable diseases, and non-communicable diseases in an effort to highlight the changes in the healthcare status of these nine countries under scrutiny. Considering that all the post-Soviet nations are officially recognized members of the World Health Organization (WHO) and have demonstrated their commitment to attaining the WHO's objectives, the evaluation of healthcare system progress and improvement was carried out utilizing indicators provided by the WHO. This review reveals that the evolution of healthcare systems could be considered sustainable, given that average life expectancy has returned to the level it was in 1991- the year of the USSR's breakup, and people's health has improved since the turn of the twenty-first century. To enhance the potential success of future healthcare reforms, however, governments must monitor implementation of the reform process, evaluate the achievement of objectives, and make necessary adjustments. The success of future healthcare changes will depend on the active involvement of the government, medical community, and patient community, as well as obtaining the support of local health authorities. This study may help identify successful and failed strategies, guiding future healthcare changes and investments.

Improving the Mental Health of Surgical Teams Through Operating Room Design.

OBJECTIVE: In this study, we aim to develop and propose an evaluation method for analyzing the design of operating rooms (ORs) from the perspective of surgical teams' reported experiences and stress levels. BACKGROUND: Stress and burnout of surgical team members can lead to diminished performance and medical errors, which endangers the safety of both the patients and team members. The design and layout of the OR play a critical role in managing such stress. METHODS: To understand surgical teams' spatial needs related to their experiences and stress, we administered a survey and in-depth focus group discussions to three surgical teams from the same organization. The identified spatial needs were translated into functional scenarios and spatial metrics, essentially viewing the OR through the perspective of users. RESULTS: Our analysis revealed four integral sections-patient flow, room organization, access to facilities/medical equipment/support staff/team members, and staff well-being-identified as critical design factors associated with the experiences and stress levels of the surgical teams in the ORs. CONCLUSIONS: We expect this method to serve as a tool for evaluating the effect of the design of OR layouts on stress, thereby supporting the well-being and resiliency of surgical teams.

Interstitial Fibrosis and Arrhythmic Mitral Valve Prolapse: Unravelling Sex-Based Differences.

Background: Interstitial fibrosis as quantified by cardiac magnetic resonance (CMR) has been demonstrated in arrhythmic mitral valve prolapse (MVP), a condition with known female predominance. However, prior studies included only MVP cases with significant mitral regurgitation (MR) or mitral annular disjunction (MAD). We sought to evaluate the association between interstitial fibrosis and complex ventricular ectopy (ComVE) in MVPs unselected for MAD or severe MR, and to investigate the contribution of sex to this association. Methods: We performed contrast CMR in consecutive individuals with MVP between 2020 and 2022. Extracellular volume fraction (ECV%), a surrogate marker for interstitial fibrosis, was quantified using T 1 mapping. Replacement fibrosis was assessed using late gadolinium enhancement (LGE). ComVE, defined as frequent premature ventricular contractions and/or non-sustained/sustained ventricular tachycardia (VT), was detected using ambulatory ECG monitoring. Results: We identified 59 MVP cases without severe MR (49% women, 80% with mild or less MR) and available ECV% measurement. Among these, 23 (39%) had ComVE, including a case of aborted ventricular fibrillation (VF) and one with sudden arrhythmic death, both females. Global ECV% was significantly greater in ComVE versus non-ComVE (31%[27-33] vs 27%[23-30], p=0.002). In MVP-ComVE, higher segmental ECV% was not limited to the inferolateral/inferior LV wall, but was also demonstrated in atypical segments including the anterior/anterolateral wall (p<0.05). The association between ComVE and ECV% was driven by female sex (32%[30-33] vs 28%[26-30], p=0.003 in females; 31%[25-33] vs 26%[23-30], p=0.22 in males). ECV% remained independently associated with an increased risk of ComVE, including VT/VF, after adjustment for cardiovascular risk factors, MAD, and LGE (p<0.01). Conclusion: In MVP without significant MR, interstitial fibrosis by CMR is associated with an increased risk of ComVE, suggesting a primary myopathic process. The stronger association between interstitial fibrosis and ComVE in females may explain why severe arrhythmic complications are more prevalent among women.

Identifying Mitral Valve Prolapse at Risk for Arrhythmias and Fibrosis From Electrocardiograms Using Deep Learning.

BACKGROUND: Mitral valve prolapse (MVP) is a common valvulopathy, with a subset developing sudden cardiac death or cardiac arrest. Complex ventricular ectopy (ComVE) is a marker of arrhythmic risk associated with myocardial fibrosis and increased mortality in MVP. OBJECTIVES: The authors sought to evaluate whether electrocardiogram (ECG)-based machine learning can identify MVP at risk for ComVE, death and/or myocardial fibrosis on cardiac magnetic resonance (CMR) imaging. METHODS: A deep convolutional neural network (CNN) was trained to detect ComVE using 6,916 12-lead ECGs from 569 MVP patients from the University of California-San Francisco between 2012 and 2020. A separate CNN was trained to detect late gadolinium enhancement (LGE) using 1,369 ECGs from 87 MVP patients with contrast CMR. RESULTS: The prevalence of ComVE was 28% (160/569). The area under the receiver operating characteristic curve (AUC) of the CNN to detect ComVE was 0.80 (95% CI: 0.77-0.83) and remained high after excluding patients with moderate-severe mitral regurgitation [0.80 (95% CI: 0.77-0.83)] or bileaflet MVP [0.81 (95% CI: 0.76-0.85)]. AUC to detect all-cause mortality was 0.82 (95% CI: 0.77-0.87). ECG segments relevant to ComVE prediction were related to ventricular depolarization/repolarization (early-mid ST-segment and QRS from V1, V3, and III). LGE in the papillary muscles or basal inferolateral wall was present in 24% patients with available CMR; AUC for detection of LGE was 0.75 (95% CI: 0.68-0.82). CONCLUSIONS: CNN-analyzed 12-lead ECGs can detect MVP at risk for ventricular arrhythmias, death and/or fibrosis and can identify novel ECG correlates of arrhythmic risk. ECG-based CNNs may help select those MVP patients requiring closer follow-up and/or a CMR.

Stroke in mitral valve prolapse: risk factors and left atrial function in cryptogenic versus non-cryptogenic ischemic subtypes.

Background and purpose: Mitral valve prolapse (MVP) has been associated with an increased risk of ischemic stroke. Older age, thicker mitral leaflets, and significant mitral regurgitation (MR) leading to atrial fibrillation have been traditionally considered risk factors for ischemic stroke in MVP. However, specific risk factors for MVP-stroke subtypes are not well defined. The aim of this study is to evaluate clinical and echocardiographic parameters, including left atrial (LA) function, in MVP with cryptogenic (C) vs. non-cryptogenic (NC) stroke. Methods: In this case-control matched study, MVPs were identified in consecutive echocardiograms obtained after a stroke from January 2013 to December2016 at the University of California, San Francisco. MVP was defined as leaflet displacement ≥2 mm in the parasternal long-axis view at end-systole. Age/gender matched MVPs without stroke and healthy controls without MVP were also identified. We analyzed LA end-systolic/diastolic volume index, emptying fraction (LAEF), function index (LAFI), and global longitudinal strain in all MVPs and controls. We also measured left ventricular (LV) volume indexes, mass index, ejection fraction (EF), degree of MR and leaflet thickness. Results: We identified a total of 30 MVPs (age 70 ± 12, 50% females) with stroke (11 with C- and 19 with NC-stroke), 20 age/gender matched MVPs without a stroke and 16 controls. MVPs without stroke had lower BMI, less hypertension but more MR (≥moderate in 45% vs. 17%), more abnormal LA function (lower LAEF, LAFI) and larger LV volumes/mass (all p < 0.05) when compared to MVPs with stroke. Leaflet thickness was overall mild (<3 mm) and similar in the 2 groups. Within the MVP stroke group, NC-stroke had higher BMI, more hypertension and more atrial fibrillation compared to C-stroke. In the variables tested, patients with C-stroke did not differ from controls. Conclusions: MVP-related MR may be protective against stroke despite abnormal LA function. Risk of NC-stroke in MVP is related to common stroke risk factors rather than mitral valve leaflet thickness. The etiology of C-stroke in MVP warrants further studies.

Endobronchial obstruction in connective tissue diseases: an uncommon but life threatening complication: two case reports.

BACKGROUND: Granulomatosis with polyangiitis and relapsing polychondritis are rare, multisystemic and potentially life-threatening connective tissue diseases. We present two cases of severe endobronchial obstruction in the aforementioned conditions and discuss difficulties with detection and treatment. Despite differing underlying pathophysiologies, endobronchial disease is a less frequently reported but serious complication of both conditions. CASE PRESENTATION: Case 1, a 31-year-old South Asian woman with relapsing polychondritis, required partial tracheal resection and reconstruction in combination with immunosuppressive therapy to achieve respiratory recovery following collapse of her right main bronchus and a stricture in her left main bronchus. Case 2, a 22-year-old Caucasian male with granulomatosis with polyangiitis, underwent surgical resection of an endobronchial growth causing occlusion of his right main bronchus. Although his respiratory status was initially stabilised with increased immunosuppression, he continues to have disease progression in spite of this. CONCLUSIONS: Our cases highlight the importance of a multidisciplinary approach combining immunosuppression with supportive care and judicious use of surgical interventions in select cases. A further review of the literature shows endobronchial obstruction is potentially under-reported due to overlap in connective tissue disease symptomatology and there is no consensus on best practice.

Mechanical Dispersion Discriminates between Arrhythmic and Non-Arrhythmic Sudden Death: From the POST SCD Study.

Background: Global longitudinal strain (GLS) and mechanical dispersion (MD) by speckle-tracking echocardiography can predict sudden cardiac death (SCD) beyond left ventricular ejection fraction (LVEF) alone. However, prior studies have presumed cardiac cause from EMS records or death certificates rather than gold-standard autopsies. Objectives: We sought to investigate whether abnormal GLS and MD, reflective of underlying myocardial fibrosis, are associated with autopsy-defined sudden arrhythmic death (SAD) in a comprehensive postmortem study. Methods: We identified and autopsied all World Health Organization-defined (presumed) SCDs ages 18-90 via active surveillance of out of hospital deaths in the ongoing San Francisco POstmortem Systematic InvesTigation of Sudden Cardiac Death (POST SCD) Study to refine presumed SCDs to true cardiac causes. We retrieved all available pre-mortem echocardiograms and assessed LVEF, LV-GLS, and MD. The extent of LV myocardial fibrosis was assessed and quantified histologically. Results: Of 652 autopsied subjects, 65 (10%) had echocardiograms available for primary review, obtained at a mean 1.5 years before SCD. Of these, 37 (56%) were SADs and 29 (44%) were non-SADs; fibrosis was quantified in 38 (58%). SADs were predominantly male, but had similar age, race, baseline comorbidities, and LVEF compared to non-SADs (all p>0.05). SADs had significantly reduced LV-GLS (median: -11.4% versus -18.5%, p=0.008) and increased MD (median: 14.8 ms versus 9.4 ms, p=0.006) compared to non-SADs. MD was associated with total LV fibrosis by linear regression in SADs (r=0.58, p=0.002). Conclusion: In this countywide postmortem study of all sudden deaths, autopsy-confirmed arrhythmic deaths had significantly lower LV-GLS and increased MD than non-arrhythmic sudden deaths. Increased MD correlated with higher histologic levels of LV fibrosis in SADs. These findings suggest that increased MD, which is a surrogate for the extent of myocardial fibrosis, may improve risk stratification and specification for SAD beyond LVEF. PERSPECTIVES: Competency in medical knowledge: Mechanical dispersion derived from speckle tracking echocardiography provides better discrimination between autopsy-defined arrhythmic vs non-arrhythmic sudden death than LVEF or LV-GLS. Histological ventricular fibrosis correlates with increased mechanical dispersion in SAD.Translational outlook: Speckle tracking echocardiography parameters, in particular mechanical dispersion, may be considered as a non-invasive surrogate marker for myocardial fibrosis and risk stratification in SCD.

The Role of Healthcare Facility Design on the Mental Health of Healthcare Professionals: A Literature Review.

OBJECTIVE: This study aims to review and synthesize the empirical evidence about the connection between healthcare facility design and the mental health of healthcare professionals by reviewing the relevant literature. BACKGROUND: Mental exhaustion of healthcare professionals is becoming a critical issue in healthcare, especially during the pandemic. The physical design of healthcare facilities has significant potential to reduce and prevent the mental exhaustion of healthcare professionals by removing environmental stressors and providing restorative experiences. However, the built environment is not fully utilized as an intervention to support healthcare professionals. METHODS: Relevant articles were identified from the Medline, PsycINFO, PubMed, and Web of Science databases using a combination of search terms representing environmental design factors and health outcomes. Identified articles were reviewed by their titles, abstracts, and full texts using the inclusion and exclusion criteria. RESULTS: The search yielded 27 empirical articles investigating the relationships between environmental design factors and staff mental health outcomes, including stress, fatigue, job satisfaction, burnout, and well-being. Healthcare design aspects that were investigated in the identified articles include overall facility and perception (e.g., aesthetic appeal and impression, belonging to the surroundings, safety), specific spaces (e.g., patient area, staff workspace), intangible elements (e.g., exterior view, light, sound), and interior space and ergonomics (e.g., material finishes, furniture). CONCLUSIONS: Through the synthesis of the current literature regarding the relationships between healthcare facility design and the mental health of healthcare professionals, this study provides implications for supporting healthcare professionals through the design of the healthcare facility.

Patients' experience of and participation in a stroke self-management programme, My Life After Stroke (MLAS): a multimethod study.

OBJECTIVE: A self-management programme, My Life After Stroke (MLAS), was developed to support stroke survivors. This evaluation reports patients' experience. DESIGN: Multimethod, involving interviews and questionnaires. SETTING: 23 general practices in the intervention arm of a cluster randomised controlled trial in East of England and East Midlands, UK. PARTICIPANTS: People on the stroke registers of participating general practices were invited to attend an MLAS programme. INTERVENTIONS: MLAS comprises one-to-one and group-based sessions to promote independence, confidence and hope. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was uptake of the programme. Participants who declined MLAS were sent a questionnaire to ascertain why. Attendees of four programmes completed evaluation forms. Attendees and non-attendees of MLAS were interviewed. Ad-hoc email conversations with the lead author were reviewed. Thematic analysis was used for qualitative data. RESULTS: 141/420 (34%) participants (mean age 71) attended an MLAS programme and 103 (73%) completed 1. 64/228 (28%) participants who declined MLAS gave reasons as: good recovery, ongoing health issues, logistical issues and inappropriate. Nearly all attendees who completed questionnaires felt that process criteria such as talking about their stroke and outcomes such as developing a strong understanding of stroke had been achieved. CONCLUSIONS: MLAS was a positive experience for participants but many stroke survivors did not feel it was appropriate for them. Participation in self-management programmes after stroke might be improved by offering them sooner after the stroke and providing a range of delivery options beyond group-based, face-to-face learning. TRIAL REGISTRATION NUMBER: NCT03353519, NIH.

Placing Users at the Center: Evaluating Exam Room Design for Improved User Experience.

OBJECTIVE: This article proposes a method for evaluating the design affordances of primary care exam rooms from the perspectives of users using functional scenario (FS) analysis. GOAL: This study aims to develop quantifiable criteria and spatial metrics for evaluating how exam room design supports the needs of different users. These criteria and metrics can be used in the early stages of the design process to choose between alternatives. BACKGROUND: The primary care exam room is an essential space in healthcare, as it is the first point of contact between the healthcare provider and the patient. However, there is a lack of rigorous evaluation metrics for exam room design that supports improved user experiences and better health outcomes. METHOD: A total of nine primary care exam rooms were analyzed using FS analysis. We identified three key user groups involved in the clinical examination process-providers, patients, and care partners-and translated their needs into FSs. We developed spatial metrics for each FS to quantify the extent to which the needs were spatially supported. RESULTS: We developed 11 FSs in total: three from the providers', five from the patients', and three from the care partners' perspectives. The results revealed possible design strategies for improved user experiences. CONCLUSIONS: We quantitatively measured the affordance of primary care exam room design for multiple stakeholders. We expect that the criteria and metrics presented in this article will improve the understanding of different users' perspectives and provide new design guidance for improved user experiences.

Clinic Design for Safety During the Pandemic: Safety or Teamwork, Can We Only Pick One?

OBJECTIVE: This article aims to illustrate the design considerations of team-based primary care clinics in response to the pandemic. BACKGROUND: Due to COVID-19, physical distancing became a critical practice in our daily life, especially in healthcare settings where healthcare professionals must continue providing care to patients despite the manifold risks. Many healthcare facilities are implementing physical distancing in their clinic layouts, and healthcare professionals are adjusting their behaviors, so they can stay away from each other. METHODS: A total of four team-based primary care clinics were studied to identify their lessons learned regarding safety measures and space usage during the pandemic. RESULTS: The four team-based primary care clinics made changes to the clinic design (e.g., waiting areas, exam rooms, team workspaces), operational protocols (e.g., in-person huddles, social gatherings, staff work locations), and usage of spaces (e.g., outdoor spaces, utility rooms). Such changes enabled the implementation of safety measures during the pandemic. However, healthcare professionals also reported challenges regarding their team communication and coordination due to physical distancing and separation. CONCLUSIONS: Our findings suggest that the physical distancing may in fact contribute to less effective teamwork and patient care and negatively affect staff well-being. In this article, we ask healthcare system leaders and designers to continue supporting both safety and teamwork by paying attention to the flexibility and spatial relationships among healthcare professionals rather than fully sacrificing teamwork for safety. Also, now is the time when multidisciplinary collaborations are needed to establish and validate guidelines that can improve both factors.

What underlies the difference between self-reported health and disability after stroke? A qualitative study in the UK.

BACKGROUND: Levels of self-reported health do not always correlate with levels of physical disability in stroke survivors. We aimed to explore what underlies the difference between subjective self-reported health and objectively measured disability among stroke survivors. METHODS: Face to face semi-structured interviews were conducted with stroke survivors recruited from a stroke clinic or rehabilitation ward in the UK. Fifteen stroke survivors purposively sampled from the clinic who had discordant self-rated health and levels of disability i.e. reported health as 'excellent' or 'good' despite significant physical disability (eight), or as 'fair' or 'poor' despite minimal disability (seven) were compared to each other, and to a control group of 13 stroke survivors with concordant self-rated health and disability levels. Interviews were conducted 4 to 6 months after stroke and data analysed using the constant comparative method informed by Albrecht and Devlieger's concept of 'disability paradox'. RESULTS: Individuals with 'excellent' or 'good' self-rated health reported a sense of self-reliance and control over their bodies, focussed on their physical rehabilitation and lifestyle changes and reported few bodily and post-stroke symptoms regardless of level of disability. They also frequently described a positive affect and optimism towards recovery. Some, especially those with 'good' self-rated health and significant disability also found meaning from their stroke, reporting a spiritual outlook including practicing daily gratitude and acceptance of limitations. Individuals with minimal disability reporting 'fair' or 'poor' self-rated health on the other hand frequently referred to their post-stroke physical symptoms and comorbidities and indicated anxiety about future recovery. These differences in psychological outlook clustered with differences in perception of relational and social context including support offered by family and healthcare professionals. CONCLUSIONS: The disability paradox may be illuminated by patterns of individual attributes and relational dynamics observed among stroke survivors. Harnessing these wider understandings can inform new models of post-stroke care for evaluation.

Designing for Effective and Safe Multidisciplinary Primary Care Teamwork: Using the Time of COVID-19 as a Case Study.

Effective medical teamwork can improve the effectiveness and experience of care for staff and patients, including safety. Healthcare organizations, and especially primary care clinics, have sought to improve medical teamwork through improved layout and design, moving staff into shared multidisciplinary team rooms. While co-locating staff has been shown to increase communication, successful designs balance four teamwork needs: face-to-face communications; situational awareness; heads-down work; perception of teamness. However, precautions for COVID-19 make it more difficult to conduct face-to-face communications. In this paper we describe a model for understanding how layout affects these four teamwork needs and describe how the perception of teamwork by staff changed after COVID-19 precautions were put in place. Observations, interviews and two standard surveys were conducted in two primary care clinics before COVID-19 and again in 2021 after a year of precautions. In general, staff felt more isolated and found it more difficult to conduct brief consults, though these perceptions varied by role. RNs, who spent more time on the phone, found it convenient to work part time-from home, while medical assistants found it more difficult to find providers in the distanced clinics. These cases suggest some important considerations for future clinic designs, including greater physical transparency that also allow for physical separation and more spaces for informal communication that are distanced from workstations.

Antemortem and Post-Mortem Characteristics of Lethal Mitral Valve Prolapse Among All Countywide Sudden Deaths.

OBJECTIVES: The goal of this study was to investigate the characteristics of mitral valve prolapse (MVP) in a post-mortem study of consecutive sudden cardiac deaths (SCDs) in subjects up to 90 years of age. BACKGROUND: Up to 2.3% of subjects with MVPs experience SCD, but by convention SCD is rarely confirmed by autopsy. In a post-mortem study of persons <40 years of age, 7% of SCDs were caused by MVP; bileaflet involvement, mitral annular disjunction (MAD), and replacement fibrosis were common. METHODS: In the San Francisco POST SCD (Postmortem Systematic Investigation of Sudden Cardiac Death) study, autopsies have been performed on >1,000 consecutive World Health Organization-defined (presumed) cases of SCD in subjects aged 18 to 90 years since 2011; a total of 603 were adjudicated. Autopsy-defined sudden arrhythmic death (SAD) required absence of nonarrhythmic cause; MVP diagnosis required leaflet billowing. One hundred antemortem echocardiograms were revised to identify additional MVPs missed on autopsy. RESULTS: Among the 603 presumed SCDs, 339 (56%) were autopsy-defined SADs, with MVP identified in 7 (1%). Six additional MVPs were identified by review of echocardiograms, for a prevalence of at least 2% among 603 presumed SCDs and 4% among 339 SADs (vs. 264 non-SADs; p = 0.02). All 6 additional MVPs had monoleaflet rather than bileaflet involvement and mild mitral regurgitation, ruling out hemodynamic cause. Less than one-half had MAD with replacement fibrosis, but all had multisite interstitial fibrosis. CONCLUSIONS: In a countywide post-mortem study of all adult cases of SCD, MVP prevalence was at least 4% of SADs, but one-half were missed on autopsy. Monoleaflet MVP was often underdiagnosed post-mortem. Compared with young cases of SCD, lethal MVP in older cases of SCD did not consistently have bileaflet anatomy, replacement fibrosis, or MAD.

The impact of clinic design on teamwork development in primary care.

BACKGROUND: Traditional clinic design supports a high-volume, hierarchical practice model. New design models are evolving to foster a high-functioning team delivery model. PURPOSE: The goal of this study was to determine whether new design models, specifically colocation, improve care team development. METHODOLOGY/APPROACH: A quasi-experimental design was used in this study to obtain validated teamwork development scores and patient satisfaction data to compare clinic design models. We took advantage of a difference in designs of primary care clinics among several clinics within the same care system in the Upper Midwest region of the United States. The participants were staff members of the primary care delivery teams in the studied clinics. The intervention was a redesign of staff space in the clinic. Our measures included a validated measure of team development and a commonly used patient satisfaction tool that were both in use at our institution at the time of the study. RESULTS: Teamwork scores were significantly higher in clinics where the primary work space of the entire team was colocated than in clinics where providers were in spaces separate from other team members. The differences in scores held across team roles, including providers, registered nurses, and licensed practical nurses. Patient satisfaction was not different. CONCLUSION: Colocation in clinic design appears to have a significant impact on team development across primary care team member roles. PRACTICE IMPLICATIONS: Primary care practice leaders should consider colocated clinic designs if their goal is to optimize care team development in support of team-based care delivery models. A more precise understanding of colocation that includes aspects such as distance to and visibility to teammates might help improve design in the future.

The Representational Function of Clinic Design: Staff and Patient Perceptions of Teamwork.

OBJECTIVE: This study empirically investigates the relationships between visibility attributes and both patients' and staff members' teamwork experiences. BACKGROUND: Teamwork among healthcare professionals is critical for the safety and quality of patient care. While a patient-centered, team-based care approach is promoted in primary care clinics, little is known about how clinic layouts can support the teamwork experiences of staff and patients in team-based primary clinics. METHODS: This article measured teamwork perceptions of staff members and patients at four primary care clinics providing team-based care. Visual access to staff workstations from both staff and patient perspectives was analyzed using VisualPower tool(version 21). The relationships between teamwork perception and visibility attributes were analyzed for each entity: staff members and patients. RESULTS: The results showed that the visual relationships among staff members and those between staff members and patients have significant associations with overall perceptions of teamwork. While clinics providing more visual connections between staff workstations reported higher teamwork perception of staff members, patient perceptions of staff teamwork were inversely related to the number of visual connections between patients and staff workstations. CONCLUSIONS: The findings of the study provide implications for designing team-based primary care clinics to enhance the teamwork experience of both staff members and patients, which is also applicable to teamwork perceptions in other settings where both inhabitants and visitors are main user groups of the spaces. This study illustrates the representational function of space: Organizations can emphasize their values via layout design by regulating what they show to inhabitants or visitors.

COVID-19: An Australian center's perspective.

SARS CoV-2 (COVID 19) is having a deep and lasting impact around the world. We review the effect it has had on our cardiothoracic surgery practice in Australia and give insights into our contingency planning, restructuring, practice changes, and the effect on our patients in this evolving pandemic.

Long-term outcomes of ablation for ventricular arrhythmias in mitral valve prolapse.

PURPOSE: Prior studies reporting efficacy of radiofrequency catheter ablation for complex ventricular ectopy in mitral valve prolapse (MVP) are limited by selective inclusion of bileaflet MVP, papillary muscle only ablation, or short-term follow-up. We sought to evaluate the long-term incidence of hemodynamically significant ventricular tachycardia (VT) or fibrillation (VF) in patients with MVP after initial ablation. METHODS: We studied consecutive patients with MVP undergoing ablation for complex ventricular ectopy between 2013 and 2017 at our institution. Of 580 patients with MVP, we included 15 (2.6%, 10 women; mean age 50 ± 14 years, 53% bileaflet) with complex ventricular ectopy treated with initial ablation. RESULTS: Over a median follow-up of 3406 (1875-6551) days or 9 years, 5 of 15 (33%) patients developed hemodynamically significant VT/VF after their initial ablation and underwent placement of an implantable cardioverter defibrillator (ICD). Three of 5 also underwent repeat ablations. Sustained VT was inducible prior to index ablation in all 5 who developed VT/VF, compared to none of the 10 patients who did not develop VT/VF after index ablation (p = 0.002). Complex ventricular ectopy at index ablation was multifocal in all 5 patients who underwent repeat intervention versus 4 of 10 patients (40%) who did not (p = 0.04). All 3 patients with subsequent VT/VF who underwent repeat ablation had a new clinically dominant focus of ventricular arrhythmia and 3 of the patients with ICD had appropriate VT/VF therapies. CONCLUSIONS: In the long term, a subset of MVP patients treated with ablation for ventricular arrhythmias, all with multifocal ectopy on initial EP study, develop hemodynamically significant VT/VF. Our findings suggest the progressive nature of ventricular arrhythmias in patients with MVP and multifocal ectopy.
