A Data-Driven Analysis of Ward Capacity Strain Metrics That Predict Clinical Outcomes Among Survivors of Acute Respiratory Failure.

Supply-demand mismatch of ward resources ("ward capacity strain") alters care and outcomes. Narrow strain definitions and heterogeneous populations limit strain literature. Evaluate the predictive utility of a large set of candidate strain variables for in-hospital mortality and discharge destination among acute respiratory failure (ARF) survivors. In a retrospective cohort of ARF survivors transferred from intensive care units (ICUs) to wards in five hospitals from 4/2017-12/2019, we applied 11 machine learning (ML) models to identify ward strain measures during the first 24 hours after transfer most predictive of outcomes. Measures spanned patient volume (census, admissions, discharges), staff workload (medications administered, off-ward transports, transfusions, isolation precautions, patients per respiratory therapist and nurse), and average patient acuity (Laboratory Acute Physiology Score version 2, ICU transfers) domains. The cohort included 5,052 visits in 43 wards. Median age was 65 years (IQR 56-73); 2,865 (57%) were male; and 2,865 (57%) were white. 770 (15%) patients died in the hospital or had hospice discharges, and 2,628 (61%) were discharged home and 964 (23%) to skilled nursing facilities (SNFs). Ward admissions, isolation precautions, and hospital admissions most consistently predicted in-hospital mortality across ML models. Patients per nurse most consistently predicted discharge to home and SNF, and medications administered predicted SNF discharge. In this hypothesis-generating analysis of candidate ward strain variables' prediction of outcomes among ARF survivors, several variables emerged as consistently predictive of key outcomes across ML models. These findings suggest targets for future inferential studies to elucidate mechanisms of ward strain's adverse effects.

Use of high flow nasal cannula in patients with acute respiratory failure in general wards under intensivists supervision: a single center observational study.

BACKGROUND: Few data exist on high flow nasal cannula (HFNC) use in patients with acute respiratory failure (ARF) admitted to general wards. RATIONALE AND OBJECTIVES: To retrospectively evaluate feasibility and safety of HFNC in general wards under the intensivist-supervision and after specific training. METHODS: Patients with ARF (dyspnea, respiratory rate-RR > 25/min, 150 < PaO2/FiO2 < 300 mmHg during oxygen therapy) admitted to nine wards of an academic hospital were included. Gas-exchange, RR, and comfort were assessed before HFNC and after 2 and 24 h of application. RESULTS: 150 patients (81 male, age 74 [60-80] years, SOFA 4 [2-4]), 123 with de-novo ARF underwent HFNC with flow 60 L/min [50-60], FiO2 50% [36-50] and temperature 34 °C [31-37]. HFNC was applied a total of 1399 days, with a median duration of 7 [3-11] days. No major adverse events or deaths were reported. HFNC did not affect gas exchange but reduced RR (25-22/min at 2-24 h, p < 0.001), and improved Dyspnea Borg Scale (3-1, p < 0.001) and comfort (3-4, p < 0.001) after 24 h. HFNC failed in 20 patients (19.2%): 3 (2.9%) for intolerance, 14 (13.4%) escalated to NIV/CPAP in the ward, 3 (2.9%) transferred to ICU. Among these, one continued HFNC, while the other 2 were intubated and they both died. Predictors of HFNC failure were higher Charlson's Comorbidity Index (OR 1.29 [1.07-1.55]; p = 0.004), higher APACHE II Score (OR 1.59 [1.09-4.17]; p = 0.003), and cardiac failure as cause of ARF (OR 5.26 [1.36-20.46]; p = 0.02). CONCLUSION: In patients with mild-moderate ARF admitted to general wards, the use of HFNC after an initial training and daily supervision by intensivists was feasible and seemed safe. HFNC was effective in improving comfort, dyspnea, and respiratory rate without effects on gas exchanges. Trial registration This is a single-centre, noninterventional, retrospective analysis of clinical data.

Intraprofessional collaboration between enrolled and registered nurses in the care of clinically deteriorating ward patients: A qualitative study.

BACKGROUND: Nurses' role in vital signs monitoring places them in an ideal position to recognise and respond to clinical deterioration in general wards. However, enrolled nurses (ENs) and registered nurses (RNs) do not always work collaboratively, and this can lead to delays in recognition and escalation of clinical deterioration in general wards. OBJECTIVES: The aim of the study was to explore the collaboration experiences between ENs and RNs in recognising and responding to clinical deterioration in general ward settings. METHODS: A qualitative descriptive study involving 12 ENs and 11 RNs was conducted in a 1250-bed tertiary hospital in Singapore using semistructured interviews. Interviews were transcribed and thematically analysed. FINDINGS: Three main themes emerged from the data analysis. The first, "reaching a collective understanding of patients' conditions', identifies nursing shift handover as the primary method of obtaining patient information essential for ENs and RNs to work collaboratively to deliver safe patient care. However, the dissociation of ENs during the handover process created information gaps on patients at risk of clinical deterioration. The second, "role expectations of each other", describes expectations that both groups of nurses had for each other's functions and responsibilities and the importance of mutual support in the nursing teamwork process. The third, "lacking in shared decision-making", depicts a top-down approach in decision-making, wherein ENs were often not engaged in the decision-making process related to patient care. CONCLUSIONS: A less-than-optimal collaborative EN-RN relationship was observed in this study, which sometimes caused delays in recognising and responding to deteriorating ward patients. This study illuminates the need for intraprofessional learning opportunities in prelicensure nursing programmes and the workplace to foster effective EN-RN collaborative practice. Nurse managers and educators are instrumental in fostering EN-RN collaboration and providing ongoing education on nursing teamwork skills and competencies.

High prevalence of early asymptomatic venous thromboembolism in anticoagulated COVID-19 patients hospitalized in general wards.

Coronavirus disease 2019 (COVID-19) is associated with coagulation activation and high incidence of venous thromboembolism (VTE) in severe patients despite routine thromboprophylaxis. Conflicting results exist regarding the epidemiology of VTE for unselected anticoagulated COVID-19 patients hospitalized in general wards. The aim of this study was to evaluate the prevalence of asymptomatic deep venous thrombosis (DVT) in unselected patients with COVID-19 recently hospitalized in general wards. We performed a systematic complete doppler ultrasound (CDU) at a median 4 days after admission in 42 consecutive COVID-19 patients hospitalized in general wards of our university hospital, irrespective of D-Dimer level, and retrospectively collected clinical, biological and outcome data from electronic charts. Thromboprophylaxis was systematically applied following a French national proposal. In our population, the prevalence of asymptomatic DVT was 19% (8/42 patients), with distal thrombosis in 7/8 cases and bilateral DVT in 4/8 cases. Symptomatic pulmonary embolism was detected in 4 (9.5%) patients, associated to DVT in one case. Compared to patients without DVT, patients with DVT were older and experienced poorer outcomes. In conclusion, prevalence of asymptomatic DVT is high in the first days of hospitalization of unselected COVID-19 patients in general wards and may be related to poor prognosis. Individualized assessment of thromboprophylaxis and early systematic screening for DVT is warranted in this context.

Incidence of in-hospital cardiac arrest at general wards before and after implementation of an early warning score.

BACKGROUND: In order to reduce the incidence of in-hospital cardiac arrest (IHCA) at general wards, medical emergency teams (MET) were implemented in the Capital Region of Denmark in 2012 as the efferent part of a track and trigger system. The National Early Warning Score (NEWS) system became the afferent part. This study aims at investigating the incidence of IHCA at general wards before and after the implementation of the NEWS system. MATERIAL AND METHODS: We included patients at least 18 years old with IHCA at general wards in our hospital in the periods of 2006 to 2011 (pre-EWS group) and 2013 to 2018 (post-EWS group). Data was obtained from a local database and the National In-Hospital Cardiac Arrest Registry (DANARREST). We calculated incidence rate ratios (IRR) for IHCA at general wards with 95% confidence interval (95% CI). Odds ratios (OR) for return of spontaneous circulation (ROSC) and 30-day survival were also calculated with 95% CI. RESULTS: A total of 444 IHCA occurred before the implementation of NEWS at general wards while 494 IHCA happened afterwards. The incidence rate of IHCA at general wards was 1.13 IHCA per 1000 admissions in the pre-EWS group (2006-2011) and 1.11 IHCA per 1000 admissions in the post-EWS group (2013-2018). The IRR between the two groups was 0.98 (95% CI [0.86;1.11], p = 0.71). The implementation did not affect the chance of ROSC with a crude OR of 1.14 (95% CI [0.88;1.47], p = 0.32) nor did it change the 30-day survival with a crude OR 1.30 (95% CI [0.96;1.75], p = 0.09). CONCLUSION: Implementation of the EWS system at our hospital did not decrease the incidence rate of in-hospital cardiac arrest at general wards.

Vital signs monitoring on general wards: clinical staff perceptions of current practices and the planned introduction of continuous monitoring technology.

OBJECTIVE: Early detection of patient deterioration and prevention of adverse events are key challenges to patient safety. This study investigated clinical staff perceptions of current monitoring practices and the planned introduction of continuous monitoring devices on general wards. DESIGN: Multi-method study comprising structured surveys, in-depth interviews and device trial with log book feedback. SETTING: Two general wards in a large urban teaching hospital in Sydney, Australia. PARTICIPANTS: Respiratory and neurosurgery nursing staff and two doctors. RESULTS: Nurses were confident about their abilities to identify patients at risk of deterioration, using a combination of vital signs and visual assessment. There were concerns about the accuracy of current vital signs monitoring equipment and frequency of intermittent observation. Both the nurses and the doctors were enthusiastic about the prospect of continuous monitoring and perceived it would allow earlier identification of patient deterioration; provide reassurance to patients; and support interdisciplinary communication. There were also reservations about continuous monitoring, including potential decrease in bedside nurse-patient interactions; increase in inappropriate escalations of patient care; and discomfort to patients. CONCLUSIONS: While continuous monitoring devices were seen as a potentially positive tool to support the identification of patient deterioration, drawbacks, such as the potential for reduced patient contact, revealed key areas that will require close surveillance following the implementation of devices. Training and improved interdisciplinary communication were identified as key requisites for successful implementation.

Nursing physical assessment for patient safety in general wards: reaching consensus on core skills.

AIMS AND OBJECTIVES: To determine consensus across acute care specialty areas on core physical assessment skills necessary for early recognition of changes in patient status in general wards. BACKGROUND: Current approaches to physical assessment are inconsistent and have not evolved to meet increased patient and system demands. New models of nursing assessment are needed in general wards that ensure a proactive and patient safety approach. DESIGN: A modified Delphi study. METHODS: Focus group interviews with 150 acute care registered nurses at a large tertiary referral hospital generated a framework of core skills that were developed into a web-based survey. We then sought consensus with a panel of 35 senior acute care registered nurses following a classical Delphi approach over three rounds. Consensus was predefined as at least 80% agreement for each skill across specialty areas. RESULTS: Content analysis of focus group transcripts identified 40 discrete core physical assessment skills. In the Delphi rounds, 16 of these were consensus validated as core skills and were conceptually aligned with the primary survey: (Airway) Assess airway patency; (Breathing) Measure respiratory rate, Evaluate work of breathing, Measure oxygen saturation; (Circulation) Palpate pulse rate and rhythm, Measure blood pressure by auscultation, Assess urine output; (Disability) Assess level of consciousness, Evaluate speech, Assess for pain; (Exposure) Measure body temperature, Inspect skin integrity, Inspect and palpate skin for signs of pressure injury, Observe any wounds, dressings, drains and invasive lines, Observe ability to transfer and mobilise, Assess bowel movements. CONCLUSIONS: Among a large and diverse group of experienced acute care registered nurses consensus was achieved on a structured core physical assessment to detect early changes in patient status. RELEVANCE TO CLINICAL PRACTICE: Although further research is needed to refine the model, clinical application should promote systematic assessment and clinical reasoning at the bedside.

Where is Noninvasive Ventilation Actually Delivered for Acute Respiratory Failure?

PURPOSE: Few studies have examined locations of noninvasive ventilation (NIV) application for acute respiratory failure (ARF). We aimed to track actual locations of NIV delivery and related outcomes. METHODS: Observational cohort study based at 8 acute care hospitals in Massachusetts on adult patients admitted for ARF requiring ventilatory support during pre-determined time intervals. RESULTS: Of 1225 ventilator starts, 499 were NIV; 209 (42%) in intensive care units (ICU), 185 (37%) in emergency departments (ED), 91 (18%) on general wards, and 14 (3%) in other units. Utilization (% of all ventilator starts) (1), success (2) and in-hospital mortality (3) rates for patients initiated on NIV in ICU, ED, and general and other wards were (1) 38, 36, 73, and 52%, (2) 60, 77, 68, and 93% and (3) 25, 12, 17, and 0%, respectively (p < 0.05 for all). Patients with acute-on-chronic lung disease (ACLD) and acute pulmonary edema (APE) were begun on NIV most often in EDs and patients with 'de novo' ARF and neurologic disorders most often in ICU's. Approximately 2/3 of patients begun on NIV outside of ICUs were transferred within 72 h to ICUs, wards or other units. CONCLUSIONS: Most NIV starts occurred in ICUs and EDs but utilization rate was highest (>50%) on general wards where a fifth of NIV starts took place. Actual location depended on etiology of ARF as patients with ACLD and APE were started more often in EDs and "de novo" ARF in ICU. NIV failure and mortality rates were higher in ICUs related to the greater proportion of patients with "de novo" ARF.

Glucose control in non-critically ill inpatients with diabetes: towards closed-loop.

Inpatient glycaemic control remains an important issue due to the increasing number of patients with diabetes admitted to hospital. Morbidity and mortality in hospital are associated with poor glucose control, and cost of hospitalization is higher compared to non-diabetes patients. Guidelines for inpatient glycaemic control in the non-critical care setting have been published. Current recommendations include basal-bolus insulin therapy, regular glucose monitoring, as well as enhancing healthcare provider's role and knowledge. In spite of growing focus, implementation in practice is limited, mainly due to increasing workload burden on staff and fear of hypoglycaemia. Advances in healthcare technology may contribute to an improvement of inpatient diabetes care. Integration of glucose measurements with healthcare records and computerized glycaemic control protocols are currently being used in some institutions. Recent interests in continuous glucose monitoring have led to studies assessing its utilization in inpatients. Automation of glucose monitoring and insulin delivery may provide a safe and efficacious tool for hospital staff to manage inpatient hyperglycaemia, whilst reducing staff workload. This review summarizes the evidence on current approaches to managing inpatient glycaemic control; its utility and limitations. We conclude by discussing the evidence from feasibility studies to date, on the potential use of closed loop in the non-critical care setting and its implication for future studies.

Impact of a palliative care initiative on end-of-life care in the general wards: a before-and-after study.

BACKGROUND: Data on deaths in the general wards of our hospital in 2007 revealed infrequent discussions on end-of-life care and excessive burdensome interventions. AIM: A physician order form to withhold inappropriate life-sustaining interventions was initiated in 2009. The use of the form was facilitated by staff educational sessions and a palliative care consult service. This study aims to evaluate the impact of these interventions in 2010. DESIGN: Retrospective medical chart review with comparisons was made for the following: baseline patient characteristics, orders concerning life-sustaining therapies, treatment provided in last 24 h of life, and discussion of specific life-sustaining therapies with patients and families. SETTINGS/PARTICIPANTS: This study included all adult patients who died in our hospital's general wards in 2007 (N = 683) versus 2010 (N = 714). RESULTS: There was an increase in orders to withhold life-sustaining therapies, such as cardiopulmonary resuscitation (66.2%-80.0%). There was a decrease in burdensome interventions such as antibiotics (44.9%-24.9%) and a small increase in palliative treatments such as analgesia (29.1%-36.7%). There were more discussions on the role of cardiopulmonary resuscitation with conversant patients (4.6%-10.2%) and families (56.5%-79.8%) (p-value all < 0.05). On multivariate analysis, the physician order form independently predicted orders to withhold cardiopulmonary resuscitation. CONCLUSIONS: A multifaceted intervention of a physician order form, educational sessions, and palliative care consult service led to an improvement in documentation of end-of-life discussions and was associated with an increase in such discussions and less burdensome treatments. There were small improvements in the proportion of palliative treatments administered.

Determinants of delirium in elderly in-patients in a general ward setting in a teaching hospital: A case control study.

Background: There is a dearth of research on risk factors of delirium among elderly inpatients in nonintensive low resource settings. Aim: To determine the risk factors of delirium in elderly inpatients in a nonintensive care unit setting. Materials and Methods: Sixty two elderly patients with delirium (cases) and 62 patients without delirium (controls) were administered a semi-structured proforma with socio-demographic variables and putative predisposing and precipitating risk factors and the Vellore screening instrument for dementia. Results: On univariate analysis, factors such as past cognitive impairment, history of nocturnal confusion and delirium, diminished daily living activities, severe medical illness, history of psychiatric illness, presence of dementia, infection, fever above 1000F, abnormal electrolytes abnormal RFT, leukocytes in urine, hypoxia, anticholinergics and benzodiazepines, emergency admission, use of physical restraints, bladder catheterization, more than routine investigations, intensive care unit admission, surgery, and duration of hospital stay more than 10 days were found to be significantly associated with delirium. On multivariate analysis with binary logistic regression, bladder catheterization (odds ratio [OR] = 13.85; confidence interval [CI] = 1.44-133.14), abnormal electrolytes (OR = 5.12; CI = 1.11-23.69), and hypoxia (OR = 75.52; CI = 4.64-1.134E3) were detected to be independently associated with delirium. Conclusion: Acute modifiable rather than long-term factors were risk factors for delirium among the elderly. An awareness of modifiable risk factors has the potential of developing targeted interventions for the early mitigation of delirium.

Impact of Remote Patient Monitoring Systems on Nursing Time, Healthcare Providers, and Patient Satisfaction in General Wards.

INTRODUCTION: Remote patient monitoring systems (RPMS) are increasingly integrated into hospital wards to improve patient safety and reduce the workload on healthcare professionals (HCPs). This study evaluates the efficacy of RPMS in general wards, focusing on their impact on nursing efficiency, patient care, HCPs, and patient satisfaction. METHODS: A comprehensive time-motion study was conducted along with surveys targeting HCPs and patients in M.S. Ramaiah Memorial Hospital, Bangalore, India, which has implemented RPMS in general wards. The study involved observing and comparing nursing activities in RPMS-equipped wards versus control wards without RPMS across various shifts. In addition, feedback on the system's impact on patient safety, overall care quality, and usability was gathered through a survey form. RESULTS: RPMS decreases the amount of time nurses spend on routine monitoring, communication, and coordination, enabling a 43.11% increase in time available for patient care. More than 89% of HCPs noted improvements in the level of care and overall patient safety. More than 80% of the HCPs also noted improvement in the patient's experience. More than 50% of HCPs find RPMS easy to use and user-friendly. More than 60% of the patients noted an overall improvement in care quality. CONCLUSION: RPMS has proven to be a valuable asset in hospital wards, enhancing patient monitoring and safety while reducing the workload on staff. In addition, significant time savings on routine tasks and high satisfaction levels from both staff and patients underscore the system's benefits.

Pharmacokinetic/Pharmacodynamic Target Attainment of Ceftazidime in Adult Patients on General Wards with Different Degrees of Renal Function: A Prospective Observational Bicenter Cohort Study.

No prospective evidence exists on the pharmacokinetic/pharmacodynamic (PK/PD) target attainment of ceftazidime in adult patients on general wards. We aimed to investigate whether the PK/PD target of ceftazidime (50% T > MIC) is attained in adult patients on general wards with adequate and impaired renal function receiving regular and guideline-recommended reduced doses of ceftazidime. In this observational, prospective, bicenter cohort study, adult patients admitted to a general ward receiving ceftazidime as part of standard care were included. Three blood samples per patient within 72 h after start of treatment were collected. Data were analyzed with nonlinear mixed effects modeling. The primary endpoint was target attainment of 50% T > MIC during the first 24 h of treatment (50% T0-24 > MIC). Forty patients were included from whom 121 blood samples were obtained. All 25/25 patients with adequate renal function, 9/10 patients with moderately impaired renal function (eGFR 30-50 mL/min/1.73 m2) and 5/5 patients with severe impaired renal function (eGFR < 30 mL/min/1.73 m2) attained 50% T0-24 > MIC when applying the clinical breakpoint MIC for Pseudomonas aeruginosa of 8 mg/L. The one patient not attaining the PK/PD target did not differ in any of the collected patients' characteristics, except that this patient was the oldest in the study population. However, age was not statistically significantly associated with clearance or volume of distribution in the population pharmacokinetic model and, therefore, not likely the cause for this patient not attaining the PK/PD target. Our results suggest ≥90% probability of the PK/PD target attainment of ceftazidime in patients on general wards with adequate and impaired renal function receiving regular and guideline-recommended reduced doses of ceftazidime for treatment of infections with Pseudomonas aeruginosa and all bacteria with lower MIC-values.

Analysis of clinical features and 7-year all-cause mortality in older male patients with non-thyroidal illness syndrome on general wards.

PURPOSE: Older patients with non-thyroidal illness syndrome (NTIS) have a poor prognosis. However, there are few studies on the association of NTIS and mortality among older inpatients on general wards. In a 7-year retrospective observational study, we aimed to investigate the clinical features of NTIS and the association of NTIS and all-cause mortality in older inpatients. METHODS: A total of 959 older male inpatients whose average age was 86.3 ± 8.1 years were enrolled and divided into the NTIS group and non-NTIS group. Cox models were performed to explore the association of thyroid hormone level and mortality. RESULTS: Patients had more respiratory disease and chronic kidney disease in the NTIS than in the non-NTIS group, especially in primary nursing care, respiratory failure and haemodialysis patients; serum total protein, albumin, prealbumin, haemoglobin, uric acid and high-density lipoprotein cholesterol levels were lower, and urea nitrogen and fasting blood glucose levels were higher, in the NTIS than in the non-NTIS group. Patients in the NTIS group had a lower survival rate over 7 years follow-up (P < 0.01). A lower free T3 level was associated with all-cause mortality with a HR of 1.50 (1.36, 1.66). Lower free T4 level was associated with reduced all-cause mortality with a HR of 0.91 (0.88, 0.94) even after adjusting for confounding factors (P < 0.01). CONCLUSIONS: Among older male inpatients, the survival rate was lower in the NTIS group. A reduced free T3 level with low albumin and Hb levels was associated with all-cause mortality; moreover, a higher free T4 in the normal range may be a strong predictor for long-term mortality risk in hospitalised older male patients.

The Impact of the COVID-19 Pandemic on Mental Health and Quality of Life in COVID-19 Department Healthcare Workers in Central Greece.

BACKGROUND: The pandemic crisis created conditions of insecurity and threat and brought about changes in social contacts and everyday life. Frontline healthcare workers (HCW) were mostly affected. We aimed to evaluate the quality of life and negative emotions in COVID-19 HCW and searched for factors influencing the above. METHODS: The present study was conducted among three different academic hospitals in central Greece (04/2020-03/2021). Demographics, attitude towards COVID-19, quality of life, depression, anxiety, stress (using the WHOQOL-BREF and DASS21 questionnaire) and the fear of COVID-19 were assessed. Factors affecting the reported quality of life were also assessed. RESULTS: The study involved 170 HCW in COVID-19 dedicated departments. Moderate levels of quality of life (62.4%), satisfaction with social relations (42.4%), working environment (55.9%) and mental health (59.4%) were reported. Stress was present in 30.6% of HCW; 20.6% reported fear for COVID-19, depression (10.6%) and anxiety (8.2%). HCW in the tertiary hospital were more satisfied with social relations and working environment and had less anxiety. Personal Protective Equipment (PPE) availability affected the quality of life, satisfaction in the work environment and the presence of anxiety and stress. Feeling safe during work influenced social relations and fear of COVID-19 Conclusion: The HCW quality of life is affected in the pandemic. Feelings of safety during work related to the reported quality of life.

Experiences of nurses practising mindfulness during self-leadership in delivering a rapid response system for general wards in a private hospital in Gauteng.

BACKGROUND:  The increased complexity of the nursing care needs of patients and acuity in general wards present nursing care challenges for nurses. Self-led nurses are attentive, taking responsibility for activating the rapid response service when a patient is starting to deteriorate. OBJECTIVES:  The purpose of this article is to describe nurses' experiences practising mindfulness during self-leadership in delivering a rapid response system (RRS) in a private hospital in Gauteng. METHOD:  A qualitative, exploratory, descriptive and contextual design was followed. Homogenous purposive sampling was used and a total of eight focus groups were conducted. Focus groups durations were between 45 min and 60 min. The data analysis was carried out through open coding on Atlas.ti using the noticing things, collecting things and thinking about things (NCT) approach. An independent coder met with the researcher during a consensus meeting and finalised the analysis. RESULTS:  The findings indicated an underlying theme of nurses being mindful in their self-leadership through the development of self-motivation and self-direction in the RRS. Three categories with six subcategories emerged from the data analysis, namely self-motivation in an RRS by the team, self-direction through role-modelling to peers and training. CONCLUSION:  Nurses practised mindfulness during self-leadership, utilising behavioural and natural reward approaches and constructive thought patterns. These findings could assist management with developing training programmes for nurses.

The features comparison between patients in the ICU and general wards and between patients with different outcomes: a 2020 COVID-19 study.

BACKGROUND: The novel 2019 coronavirus (COVID-19) has largely abated in China; however, sporadic or imported cases are still a concern, while in other countries, the COVID-19 pandemic persists as a major health crisis. METHODS: All patients enrolled in this study were diagnosed with COVID-19 from February 21, 2020 to April 14, 2020 in Wuhan. We retrospectively analyzed the patients admitted to the ICU (137 patients) and general wards (114 patients) of Wuhan Leishenshan Hospital in China. The population characteristics, symptoms, and laboratory examination results between the patients in the ICU and those in the general wards were compared. Furthermore, the differences between the deceased patients in the ICU and those discharged from the ICU were compared. RESULTS: There were significant differences between the two groups in terms of symptoms, including fever, shortness of breath, no presence of complications, presence of 1 complication, and presence of 3 or more complications (P<0.05). There were also significant differences between the patients in terms of the laboratory examination results including elevated urea nitrogen, creatinine, direct bilirubin, aspartate aminotransferase, total protein, albumin, creatine kinase, lactate dehydrogenase, procalcitonin, erythrocyte sedimentation rate, white blood cells, C-reactive protein, prothrombin time, activated partial thromboplastin time, fibrinogen, D-dimer, interleukin 6, interleukin 8, interleukin 10, interleukin 2 receptor, tumor necrosis factor-α, troponin I, phosphokinase isoenzyme-MB, and B-type natriuretic peptide; and decreased platelets, lymphocyte absolute value, and eosinophil absolute value (<0.05). There were 45 patients who died in ICU and 57 improved and discharged patients. There were significant differences between the two groups in the number of patients that had 1 complication and 3 or more complications (P<0.05). There were also significant differences in the laboratory examination results between the patients including elevated urea nitrogen, total bilirubin, direct bilirubin, aspartate aminotransferase, procalcitonin, white blood cells, interleukin 8, interleukin 10, phosphokinase isoenzyme-MB, and B-type natriuretic peptide; and decreased platelets and eosinophil absolute value (P<0.05). CONCLUSIONS: Our findings highlight that the identified determinants may help to improve treatment of COVID-19 patients, to predict the risk of developing severe illness and to optimizing arrangement of health resources.

Method of respiratory rate measurement using a unique wearable platform and an adaptive optical-based approach.

BACKGROUND: An efficient and accurate method of respiratory rate measurement is still missing in hospital general wards and triage. The goal of this study is to propose a method of respiratory rate measurement that has a potential to be used in general wards, triage, and different hospital settings with comparable performance. We propose a method of respiratory rate measurement that combines a unique wearable platform with an adaptive and optical approach. The optical approach is based on a direct-contact optical diffuse reflectance phenomenon. An adaptive algorithm is developed that computes the first respiratory rate and uses it to select a band. The band then chooses a set of unique optimized parameters in the algorithm to calculate and improve the respiratory rate. We developed a study to compare the proposed method against reference manual counts from 82 patients diagnosed with respiratory diseases. RESULTS: We found good agreement between the proposed method of respiratory rate measurement and reference manual counts. The performance of the proposed method highlighted deviations with a 95% confidence interval (C.I.) of - 3.34 and 3.67 breaths per minute (bpm) and a mean bias and standard deviation (STD) of 0.05 bpm and 2.56 bpm, respectively. CONCLUSIONS: The performance of the proposed method of respiratory rate measurement is comparable with current manual counting and other respiratory rate devices reported. The method has additional advantages that include ease-of-use, quick setup time, and being mobile for wider clinical use. The proposed method has the potential as a tool to measure respiratory rates in a number of use cases.

Development and psychometric evaluation of the Relocation Stress Syndrome Scale-Short Form for patients transferred from adult intensive care units to general wards.

OBJECTIVE: This study aimed to develop the Relocation Stress Syndrome Scale-Short Form as an assessment tool for relocation stress experienced by intensive care unit patients after transfer to general wards. METHODS: This study included 535 intensive care unit patients at two tertiary care hospitals in South Korea from May to December 2018. Data were collected through face-to-face interview, using a structured questionnaire. Study 1 was conducted to estimate the factorial structure, and reliability of the scale. Study 2 was conducted to confirm the factorial structure of the scale. MAIN OUTCOMES: Study 1 found that the new instrument had a good reliability (α = 0.92) and validity. In study 2, confirmatory factor analysis supported a three-factor structure and the scale continued to demonstrate good psychometric properties. The criterion validity showed that a low level of relocation stress syndrome was associated with higher satisfaction with the transfer process (r = -0.58, p < .001) and good general health status (r = -0.51, p < .001). CONCLUSION: The 10-item Relocation Stress Syndrome Scale was developed with appropriate validity and reliability. This scale can be used to assess relocation stress of patients in transition periods. This new scale requires cross-cultural validation.
