Illuminating the dark spaces of healthcare with ambient intelligence.

Advances in machine learning and contactless sensors have given rise to ambient intelligence-physical spaces that are sensitive and responsive to the presence of humans. Here we review how this technology could improve our understanding of the metaphorically dark, unobserved spaces of healthcare. In hospital spaces, early applications could soon enable more efficient clinical workflows and improved patient safety in intensive care units and operating rooms. In daily living spaces, ambient intelligence could prolong the independence of older individuals and improve the management of individuals with a chronic disease by understanding everyday behaviour. Similar to other technologies, transformation into clinical applications at scale must overcome challenges such as rigorous clinical validation, appropriate data privacy and model transparency. Thoughtful use of this technology would enable us to understand the complex interplay between the physical environment and health-critical human behaviours.

Improving regional medical laboratory center report quality through a report recall management system.

OBJECTIVES: Currently, most medical laboratories do not have a dedicated software for managing report recalls, and relying on traditional manual methods or laboratory information system (LIS) to record recall data is no longer sufficient to meet the quality management requirements in the large regional laboratory center. The purpose of this article was to describe the research process and preliminary evaluation results of integrating the Medical Laboratory Electronic Record System (electronic record system) laboratory report recall function into the iLab intelligent management system for quality indicators (iLab system), and to introduce the workflow and methods of laboratory report recall management in our laboratory. METHODS: This study employed cluster analysis to extract commonly used recall reasons from laboratory report recall records in the electronic record system. The identified recall reasons were validated for their applicability through a survey questionnaire and then incorporated into the LIS for selecting recall reasons during report recall. The statistical functionality of the iLab system was utilized to investigate the proportion of reports using the selected recall reasons among the total number of reports, and to perform visual analysis of the recall data. Additionally, we employed P-Chart to establish quality targets and developed a "continuous improvement process" electronic flow form. RESULTS: The reasons for the recall of laboratory reports recorded in the electronic recording system were analyzed. After considering the opinions of medical laboratory personnel, a total of 12 recall reasons were identified, covering 73.05 % (1854/2538) of the recalled laboratory reports. After removing data of mass spectra lab with significant anomalies, the coverage rate increased to 82.66 % (1849/2237). The iLab system can generate six types of statistical graphs based on user needs, including statistical time, specialty labs (or divisions), test items, reviewers, reasons for report recalls, and distribution of the recall frequency of 0-24 h reports. The control upper limit of the recall rate of P-Chart based on laboratory reports can provide quality targets suitable for each professional group at the current stage. Setting the five stages of continuous process improvement reasonably and rigorously can effectively achieve the goal of quality enhancement. CONCLUSIONS: The enhanced iLab system enhances the intelligence and sustainable improvement capability of the recall management of laboratory reports, thus improving the efficiency of the recall management process and reducing the workload of laboratory personnel.

The impact of a hospital-based special care unit on behavioural and psychological symptoms in older people living with dementia.

BACKGROUND: Hospital patients with behavioural and psychological symptoms of dementia (BPSD) are vulnerable to a range of adverse outcomes. Hospital-based Special Care Units (SCUs) are secure dementia-enabling environments providing specialised gerontological care. Due to a scarcity of research, their value remains unconfirmed. OBJECTIVE: To compare hospital based SCU management of BPSD with standard care. DESIGN: Single-case multiple baseline design. SETTING AND PARTICIPANTS: One-hundred admissions to an 8-bed SCU over 2 years in a large Australian public hospital. METHODS: Repeated measures of BPSD severity were undertaken prospectively by specialist dementia nurses for patients admitted to a general ward (standard care) and transferred to the SCU. Demographic and other clinical data, including diagnoses, medication use, and care-related outcomes were obtained from medical records retrospectively. Analysis used multilevel models to regress BPSD scores onto care-setting outcomes, adjusting for time and other factors. RESULTS: When receiving standard care, patients' BPSD severity was 6.8 (95% CI 6.04-7.64) points higher for aggression, 15.6 (95% CI 13.90-17.42) points higher for the neuropsychiatric inventory, and 5.8 (95% CI 5.14-6.50) points higher for non-aggressive agitation compared to SCU. Patients receiving standard care also experienced increased odds for patient-to-nurse violence (OR 2.61, 95% CI 1.67-4.09), security callouts (OR 5.39 95% CI 3.40-8.52), physical restraint (OR 17.20, 95% CI 7.94-37.25) and antipsychotic administration (OR 3.41, 95% CI 1.60-7.24). CONCLUSION: Clinically significant reductions in BPSD and psychotropic administration were associated with SCU care relative to standard ward care. These results suggest more robust investigation of hospital SCUs, and dementia-enabling design are warranted.

Visibility-based layout of a hospital unit - An optimization approach.

A patient fall is one of the adverse events in an inpatient unit of a hospital that can lead to disability and/or mortality. The medical literature suggests that increased visibility of patients by unit nurses is essential to improve patient monitoring and, in turn, reduce falls. However, such research has been descriptive in nature and does not provide an understanding of the characteristics of an optimal inpatient unit layout from a visibility-standpoint. To fill this gap, we adopt an interdisciplinary approach that combines the human field of view with facility layout design approaches. Specifically, we propose a bi-objective optimization model that jointly determines the optimal (i) location of a nurse in a nursing station and (ii) orientation of a patient's bed in a room for a given layout. The two objectives are maximizing the total visibility of all patients across patient rooms and minimizing inequity in visibility among those patients. We consider three different layout types, L-shaped, I-shaped, and Radial; these shapes exhibit the section of an inpatient unit that a nurse oversees. To estimate visibility, we employ the ray casting algorithm to quantify the visible target in a room when viewed by the nurse from the nursing station. The algorithm considers nurses' horizontal visual field and their depth of vision. Owing to the difficulty in solving the bi-objective model, we also propose a Multi-Objective Particle Swarm Optimization (MOPSO) heuristic to find (near) optimal solutions. Our findings suggest that the Radial layout appears to outperform the other two layouts in terms of the visibility-based objectives. We found that with a Radial layout, there can be an improvement of up to 50% in equity measure compared to an I-shaped layout. Similar improvements were observed when compared to the L-shaped layout as well. Further, the position of the patient's bed plays a role in maximizing the visibility of the patient's room. Insights from our work will enable understanding and quantifying the relationship between a physical layout and the corresponding provider-to-patient visibility to reduce adverse events.

Physiotherapy in acute geriatrics wards: What (de)motivates patients? A qualitative study based on self-determination theory.

BACKGROUND: While the benefits of physiotherapy for hospitalized older patients (HOPs) are well established, these patients are often considered demotivated by healthcare team members (HTMs), which is perceived as a hindrance to their rehabilitation. The quantitative data currently available on the lack of involvement of HOPs are mainly measures of mobility. Motivation as such has, to our knowledge, never been measured. Therefore, this study aims to quantify for the first time the motivation levels of HOPs in their participation in activities of daily living (ADLs) and physiotherapy, and to explore the motivating factors behind their participation in physiotherapy. METHODS: The motivation of 60 older patients hospitalized in an acute geriatrics ward was quantified using the Scale of Demotivation Assessment (SDA). Out of these participants, 14 were interrogated through individual semi-structured face-to-face interviews. After transcription, data were analyzed according to Self-Determination Theory, which has been proven effective in the understanding of motivational mechanisms. RESULTS: The prevalence of demotivation was 47% (95% CI: [0.34;0.6]) for ADLs and 35% (95% CI: [0.23;0.48]) for physiotherapy. The main demotivating factors were the feeling of external control (lack of autonomy) and dependance experienced by HOPs, as well as the limited availability of staff during hospitalization. Conversely, feelings of competence, security, respect for limits, and commitment from the HTMs were important motivating factors. CONCLUSION: A large number of relational factors have an impact on the motivation of HOPs regarding their participation in ADLs and in physiotherapy sessions. Appropriate time and space organizing and the provision of suitable equipment, combined with a genuine caring and respectful attitude from the HTMs, could considerably encourage the expression of intrinsic motivation and thus the involvement of HOPs in their own care program.

Organizational characteristics of highly specialized units for people with dementia and severe challenging behavior.

BACKGROUND: People with dementia and severe challenging behavior in the Netherlands can be temporarily admitted to highly specialized units when their behavior is not manageable in regular dementia special care units (DSCUs). With scarce evidence available for the treatment of these patients, treatment in these units is in a pioneering phase. To gain more insight into these units, this study investigated organizational characteristics, i.e. admission and discharge characteristics, staffing, the physical environment, and the management of severe challenging behavior. METHODS: Three data collection methods were used: 1) a digital questionnaire to be completed by the unit manager, 2) an interview with the physician responsible for medical care and often another practitioner, and 3) an observation of the physical environment for which the OAZIS-dementia questionnaire was used. Descriptive analysis was used for quantitative data and thematic analysis for qualitative data, after which data was interpreted together. Thirteen units participated, with their sizes ranging from 10 to 28 places. RESULTS: Patients were mainly admitted from regular DSCUs, home or mental health care, and discharged to regular DSCUs. A multidisciplinary team comprising at least an elderly care physician or geriatrician, psychologist, and nursing staff member and other therapists as needed provided the treatment. Nursing staff hours per patient considerably differed among units. Nursing staff played a central role in the treatment. Competences such as reflectiveness on one's own behavior, and being able to cope with stressful situations were described as relevant for nursing staff. Investing in a stable nursing staff team was described as important. The units varied in whether their work-up was more intuitive or methodological. In the diagnostic phase, observation together with an extensive analysis of the patient's biography was essential. The units used a broad variety of interventions, and all paid attention to sensory stimuli. In the observation of the physical environment, the safety scored well and domesticity relatively low. CONCLUSION: Highly specialized units show strong heterogeneity in organizational characteristics and management, which can be understood in the light of the pioneering phase. Despite this, similarities were found in nursing staff roles, frequent multidisciplinary evaluation, and attention to sensory stimuli.

Perioperative pain management intervention in older patients with hip fracture in an orthogeriatric unit. A controlled before/after study assessing an audit and feedback intervention (PAIN-AGE).

BACKGROUND: Postoperative pain delays ambulation, extends hospital stay, reduces the probability of recovery, and increases risk of long-term functional impairment. Pain management in hip fractured patients poses a challenge to the healthcare teams. Older adults are more vulnerable to opioid-associated side effect and it is primordial to minimize their exposure to opioids. Acetaminophen is associated with reduced opioid use so we need to focus on acetaminophen use in first-line analgesia. METHODS: We conducted a controlled before/after study to assess the ability of an audit and feedback (A&F) intervention built with nurses to improve the quality of perioperative pain management in older patients hospitalized for hip fracture in an orthogeriatric unit (experimental group) versus a conventional orthopedic unit (no A&F intervention). The primary endpoint was the percentage of patients who received 3 g/day of acetaminophen during the three postoperative days, before and after the A&F intervention. Secondary endpoints included nurses' adherence to medical prescriptions, clinical data associated with patients and finally factors associated with intervention. The significative level was set at 0.05 for statistical analysis. RESULTS: We studied data from 397 patients (mean age 89 years, 75% female). During the postoperative period, 16% of patients from the experimental group received 3 g/day of acetaminophen before the A&F intervention; the percentage reached 60% after the intervention. The likelihood of receiving 3 g/day of acetaminophen during the postoperative period and adhering to the medical prescription of acetaminophen were significantly increased in the experimental group as compared with the control group. The patient's functional status at discharge (assessed by Activities of Daily Living scores) was significantly better and the length of hospital stay significantly reduced after the A&F intervention. CONCLUSION: Our controlled before/after study showed that an A&F intervention significantly improved perioperative pain management in older adults hospitalized for hip fracture. Involving teams in continuous education programs appears crucial to improve the quality of pain management and ensure nurses' adherence to medical prescriptions.

A Quality Improvement Project to Revise and Reduce Nursing Data Entry in a Pediatric Trauma Unit.

ABSTRACT: Meaningful direct nurse-patient interactions have been found to positively influence patient experiences and outcomes while increasing nurse satisfaction. Through redesigning a database, this process improvement project reduced nurse data entry time, allowing more opportunities for direct patient interactions. This project demonstrated that database redesign is a strategic action to decrease nurse data entry workload that can be used in hospital settings.

Association between the quantity of stroke care units and the complement of neurosurgical and neurology specialists in Japan: A retrospective study.

BACKGROUND: Stroke care units provide advanced intensive care for unstable patients with acute stroke. We conducted a survey to clarify the differences in stroke care units between urban and regional cities and the relationship between the number of stroke care unit beds and neurologists. METHODS: This retrospective observational study was conducted in 2,857 and 4,184 hospitals in urban and regional cities in 47 provinces of Japan, respectively, between January 2020 and August 2023. Tokyo and ordinance-designated cities in provinces were defined as urban cities, and those without such cities were defined as regional cities. The primary endpoint was the presence or absence of a stroke care unit. RESULTS: Multiple linear regression analysis revealed that the presence of stroke care units was significantly associated with the number of neurosurgical specialists. Receiver operating characteristic curve analysis was performed to predict the number of personnel required for stroke care unit installation based on the number of neurosurgical specialists. The area under the receiver operating characteristic curve, Youden index, sensitivity, and specificity were 0.721, 0.483, 0.783, and 0.700, respectively. CONCLUSIONS: Our study underscores the indispensability of SCUs in stroke treatment, advocating for a strategic allocation of medical resources, heightened accessibility to neurosurgical specialists, and a concerted effort to address geographic and resource imbalances. The identified cutoff value of 8.99 neurosurgical specialists per 100,000 population serves as a practical benchmark for optimizing SCU establishment, thereby potentially mitigating stroke-related mortality.

Information Management in Hospital Unit Daily Operations: A Descriptive Study With Nurses and Physicians.

Operations management of a hospital unit is a shared activity involving nursing and medical professionals, characterized by suddenly changing situations, constant interruptions, and ad hoc decision-making. Previous studies have explored the informational needs affecting decision-making, but only limited information has been collected regarding factors affecting information management related to the daily operations of hospital units. The aim of this study was to describe the experiences of nursing and medical professionals of information management in the daily operations of hospital units. This qualitative study consists of interviews following the critical incidence technique. Twenty-six nurses and eight physicians working in operational leadership roles in hospital units were interviewed, and the data were subjected to thematic analysis. The data analysis showed that strengths of current systems were organizational operational procedures, general instruments supporting information management, and a digital operations dashboard, whereas opportunities for improvement included the information architecture, quality of information, and technology use. The study findings highlight that despite several decades of efforts to provide solutions to support information management in hospital daily operations, further measures need to be taken in developing and implementing information systems with user-centered strategies and systematic approaches to better support healthcare professionals.

Pay practices and safety organizing: Evidence from hospital nursing units.

BACKGROUND: Our understanding of how highly reliable care delivery is brought about remains elusive, in part, because there is limited evidence regarding the organizational practices that enable safety organizing-the behaviors and processes underlying high reliability. PURPOSE: Because safety organizing relies on discretionary effort and lowering barriers to sharing expertise and discussing threats to safety and errors, we investigate three pay practices and their effects on information sharing and, in turn, safety organizing. Specifically, we examine average pay level, minimum pay rates, and pay dispersion on nursing units and their relationship with information sharing and safety organizing. METHOD: Cross-sectional analyses of survey data from 1,461 registered nurses in 45 nursing units in three Midwestern hospitals on safety organizing linked to administrative data on pay practices from the organization's human resource systems. Pay data and survey responses were aggregated to the nursing unit level. PROCESS and structural equation modeling were used to simultaneously test for direct and indirect effects of pay variables on information sharing and safety organizing. RESULTS: PROCESS and Mplus path analysis indicated that paying a higher minimum rate in the unit and having lower pay dispersion have indirect, desirable associations with safety organizing through information sharing. CONCLUSION: Pay practices can help organizations enhance safety organizing. In particular, higher pay rates for the lowest level nurses and lower pay dispersion among nurses are associated with unit-level information sharing and safety organizing. PRACTICE IMPLICATIONS: Having pay practices associated with lower within-unit variation and higher pay for the lowest paid members of a unit may be viable strategies for greater information sharing and safety organizing.

[Evaluation of the state and implementation of the Hospital Clinical Forensic Units in Chile]. / Evaluación del estado e implementación de las Unidades Clínico Forense Hospitalarias en Chile.

BACKGROUND: Sexual violence has a several negative impact on women's health. Thus, the health system is a gateway for the multisector response to victims. In 2018, the Clinical Forensic Hospital Units (UCFH) in Chile were launched for this purpose. OBJECTIVE: To evaluate the state of implementation of the UCFH in the health services (HS) in Chile. METHOD: This is a quantitative descriptive, cross-sectional study. A survey was designed and applied through the Google Forms platform to the managers of the care and prevention network for victims of sexual violence (VSV) of each SS. The contact of each manager was requested by each HS in three ways: transparency law, lobby law, and telephone. Each HS was classified according to the existence or not of UCFH and for each unit the availability of resources was evaluated according to the recommendations of the Technical Standard of Attention to VSV of the Ministry of Health. Also, the functioning of each unit during the pandemic was evaluated. RESULTS: Twenty-four of the 29 HSs responded, of which 12 reported having UCFH. Of the 12 units, 50% had complete infrastructure, 58.3% had complete instruments, none had full human resources, 50% had partial HR, 50% had sampling complete, and 58. 3% had full health benefits. The function during the pandemic was affected in 25% of the units. CONCLUSION: Challenges persist in the implementation of the UCFH, with special limitations in the availability of human resources.

[Staff hebdomadaire qualité et gestion des risques en gériatrie: un outil d'appropriation de la démarche qualité pour le management des unités]. / Staff hebdomadaire qualité et gestion des risques en gériatrie : un outil d'appropriation de la démarche qualité pour le management des unités.

The quality approach has become essential in geriatric hospital services, but also in the medico-social sector. This process is continuous and shared by all those in charge of the care units, to facilitate unit management and support caregivers in this approach. The weekly structured quality staff meeting is a relevant tool to facilitate the understanding and appropriation of this approach by the medical and nursing managers of the care units.

Improving Telemetry use in the Acute Assessment Unit.

BACKGROUND AND AIMS: Despite published guidelines, telemetry use is inappropriate in 25-43% of cases. This impacts patient safety and telemetry effectiveness. QI methodology was used to review telemetry in a hospital acute medical unit with the aim of reducing inappropriate use and addressing alarm fatigue. METHODS: A 'Telemetry Indication Form' was created. Eight weeks of baseline data was collated before introducing the 'Indication Form'. Four plan-do-study-act cycles were conducted. At each cycle, data was analysed using statistical process control charts. RESULTS: Inappropriate telemetry use significantly reduced from 32% to 4%. Total telemetry use also fell. Unfortunately, interventions to address alarm rates did not result in significant reduction in false alarms. CONCLUSIONS: A 'Telemetry Indication Form' has significant potential to improve patient safety through reducing inappropriate use.

Effectiveness of a Multi-component Delirium Prevention Program Implemented on General Medicine Hospital Units: an Interrupted Time Series Analysis.

BACKGROUND: Delirium is among the most prevalent harmful events in hospitals that is associated with an elevated risk for severe outcomes such as functional decline, falls, longer length of stay, and increased mortality. OBJECTIVE: To evaluate the impact of the implementation of a multi-component delirium program on the prevalence of delirium and the incidence of falls among patients staying on general medicine inpatient hospital units. DESIGN: A pre-post intervention study using retrospective chart abstraction and interrupted time series analysis. COHORT: Patients were selected from adult patients that stayed at least 1 day on one of the five general medicine units in a large community hospital in Ontario, Canada. A total of 16 random samples of 50 patients per month for 8 consecutive months pre-intervention (October 2017 to May 2018) and 8 months post intervention (January 2019 to August 2019) were selected for a total of 800 patients. There were no exclusion criteria. INTERVENTION: The delirium program included multiple components: education of staff and hospital leadership, twice per day bed-side screen for delirium, non-pharmacological and pharmacological prevention, and intervention strategies and a delirium consultation team. MEASUREMENT: Delirium prevalence was assessed using the evidence-based delirium chart abstraction method, CHART-del. Demographic data as well as fall incidence were also collected. RESULT: Our evaluation showed that the implementation of a multicomponent delirium program led to a reduction in delirium prevalence and fall incidences. The reduction in both delirium and falls was the largest for patients in the ages between 72 and 83 years old and varied across inpatient units. CONCLUSION: A multi-component delirium program to improve the prevention, recognition, and management of delirium reduces the prevalence of delirium and fall incidence among patients in general medicine units.

A new door to a different world: opportunities from the metaverse and the raise of meta-medical laboratories.

OBJECTIVES: In the digital age, the metaverse has emerged with impressive potential for many segments of society. The metaverse could be presented as a parallel dimension able to enhance the physical world as well as our actions and decisions in it with the objective to use a coalition between the natural and virtual worlds for value creation. Our aim was to elaborate on the impact of the metaverse on laboratory medicine. METHODS: Based on the available evidence, literature and reports, we analyzed the different perspectives of the metaverse on laboratory medicine and the needs for an efficient transition. RESULTS: The convergence and integration of technologies in the metaverse will participate to the reimagination of laboratory medicine services with augmented services, users' experiences, efficiency, and personalized care. The revolution around the metaverse offers different opportunities for laboratory medicine but also open multiple related challenges that are presented in this article. CONCLUSIONS: Scientific societies, multidisciplinary teams and specialists in laboratory medicine must prepare the integration metaverse and meta-medical laboratories, raise the awareness, educate, set guidance to obtain a maximum of value and mitigate potential adverse consequences.

Planning and implementing practice changes in Ontario maternal-newborn hospital units: a secondary qualitative analysis.

BACKGROUND: Moving evidence into practice is complex, and pregnant and birthing people and their infants do not always receive care that aligns with the best available evidence. Implementation science can inform how to effectively move evidence into practice. While there are a growing number of examples of implementation science being studied in maternal-newborn care settings, it remains unknown how real-world teams of healthcare providers and leaders approach the overall implementation process when making practice changes. The purpose of this study was to describe maternal-newborn hospital teams' approaches to implementing practice changes. We aimed to identify what implementation steps teams take (or not) and identify strengths and potential areas for improvement based on best practices in implementation science. METHODS: We conducted a supplementary qualitative secondary analysis of 22 interviews completed in 2014-2015 with maternal-newborn nursing leaders in Ontario, Canada. We used directed content analysis to code the data to seven steps in an implementation framework (Implementation Roadmap): identify the problem and potential best practice; assemble local evidence; select and customize best practice; discover barriers and drivers; tailor implementation strategies; field-test, plan evaluation, prepare to launch; launch, evaluate, and sustain. Frequency counts are presented for each step. RESULTS: Participants reported completing a median of 4.5 of 7 Implementation Roadmap steps (range = 3-7), with the most common being identifying a practice problem. Other steps were described less frequently (e.g., selecting and adapting evidence, field-testing, outcome evaluation) or discussed frequently but not optimally (e.g., barriers assessment). Participants provided examples of how they engaged point-of-care staff throughout the implementation process, but provided fewer examples of engaging pregnant and birthing people and their families. Some participants stated they used a formal framework or process to guide their implementation process, with the most common being quality improvement approaches and tools. CONCLUSIONS: We identified variability across the 22 hospitals in the implementation steps taken. While we observed many strengths, we also identified areas where further support may be needed. Future work is needed to create opportunities and resources to support maternal-newborn healthcare providers and leaders to apply principles and tools from implementation science to their practice change initiatives.

Patterns and rates of confirmed transfer of care of patients with juvenile idiopathic arthritis at a tertiary paediatric rheumatology centre.

BACKGROUND: Disease activity in juvenile idiopathic arthritis (JIA) commonly persists into adulthood. Transfer of JIA patients to adult healthcare services can be challenging, with prior studies showing poor rates of success. AIMS: This audit sought to examine characteristics of patients undergoing transfer of care within the rheumatology unit at the Royal Children's Hospital in Melbourne, with the aim of identifying areas for improvement. Specifically, we sought to determine the rate at which confirmation of established care with an adult service (confirmed transfer of care) was documented in the patient chart. METHODS: Patients with a diagnosis of JIA who turned 18 years of age between 2012 and 2019 were identified. A chart review was undertaken to collect relevant data. RESULTS: One hundred and seventy-seven patients were identified. In all, 64% (114/177) were referred for adult care. The commonest JIA subtypes referred were seronegative polyarticular (35/114; 30.7%) and oligoarticular JIA (22/114; 19.3%). Documentation of confirmed transfer of care occurred in 62.3% (71/114), with correspondence received from adult services in 49.1% (56/114). There was no difference in rate of return correspondence from public versus private providers (45% vs 53.8%; P = 0.38). The use of 'backstop appointments' was more likely in those with confirmed transfer of care (66% vs 30%; P = 0.0002). CONCLUSIONS: Lack of confirmed transfer of care for JIA patients is common and carries a risk of suboptimal outcomes. Strategies to improve communication with adult services, the routine use of 'backstop' appointments and vigilance regarding potential loss to follow up at the time of transfer would minimise this risk.

Is there a 'weekend effect' on mortality among hospitalised patients in an internal medicine ward? A retrospective study.

BACKGROUND: Previous studies demonstrated a 'weekend effect' and a 'night effect' of increased mortality among patients admitted during weekends or night shifts, presumably due to understaffing. AIMS: To examine whether death during hospitalisation follows a similar effect regardless of admission time. METHODS: A retrospective cohort study among deceased patients hospitalised in the internal medicine wing of a tertiary medical centre in Israel, between 2019 and 2020. Demographic and medical data were retrieved from electronic medical charts. Causes of death were specifically categorised. We applied statistical models to test for differences in mortality using incidence rate ratio (IRR) according to the day, time and cause of death. RESULTS: One thousand, two hundred and seventy-eight deceased patients were included. All-cause mortality was similar between weekends and weekdays. When sepsis was the cause of death, higher IRR were demonstrated on Fridays in comparison with weekdays (IRR 1.4; 95% confidence interval (CI) 1.1-1.9; P < 0.05). Other causes of death were not consistent with a 'weekend effect'. Mortality during night shifts was higher in comparison with the afternoon (IRR 1.5; 95% CI 1.3-4.7) and similar to the morning (IRR 1; 95% CI 0.9-1.2). CONCLUSION: Our study did not find a pattern of 'weekend effect' or 'night effect' on all-cause mortality among hospitalised patients in internal medicine wards. Our findings suggest that perhaps specifically death from sepsis, and not all-cause mortality, can be used as a surrogate for the measurement of understaffing or quality of care in the internal ward.

Characterization of patients admitted to specialized geriatric acute care hospital units with the German version of the Standardized Evaluation and Intervention for Seniors at Risk (SEISAR) screening-instrument: a cross-sectional study.

BACKGROUND: The Standardized Evaluation and Intervention for Seniors at Risk (SEISAR) screening tool records major geriatric problems, originally applied in the emergency department. Particularly, the distinction of compensated and uncompensated problems is an interesting and new approach. Therefore, we translated the SEISAR in German language and used it to characterize patients in specialized geriatric hospital wards in Germany and to gather initial experience regarding its usability and practicability. METHODS: The tool was translated by three independent specialists in geriatric medicine and backtranslated for quality-assurance by a non-medical English native speaker. In a second step, 8 acute care geriatric hospital departments used the translated version to characterize all consecutive patients admitted over a period of one month between December 2019 and May 2020 at time of admission. RESULTS: Most of the 756 patients (78%) lived in an own apartment or house prior to hospital admission. Participants had on average 4 compensated and 6 uncompensated problems, a Barthel-Index of 40 pts. on admission with a median increase of 15 points during hospital stay, and a median length of stay of 16 days in the geriatric hospital department. CONCLUSION: SEISAR is an interesting standardized brief comprehensive geriatric assessment tool for the identification of compensated and uncompensated health problems in older persons. The data of this study highlights the number, variability, and complexity of geriatric problems in patients treated in specialized acute care geriatric hospital wards in Germany. TRIAL REGISTRATION: German Clinical trial register (DRKS-ID: DRKS00031354 on 27.02.2023).
