With advancement in health technology comes great responsibility - Ethical and safety considerations for using digital health technology: A narrative review.

The accelerated adoption of digital health technologies in the last decades has raised important ethical and safety concerns. Despite the potency and usefulness of digital health technologies, addressing safety, and ethical considerations needs to take greater prominence. This review paper focuses on ethical and safety facets, including health technology-related risks, users' safety and well-being risks, security and privacy concerns, and risks to transparency and diminished accountability associated with the utilization of digital health technologies. In order to maximize the potential of health technology benefits, awareness of safety risks, and ethical concerns should be increased, and the use of appropriate strategies and measures should be considered.

Depression predicts delayed return to daily activities in patients post-cardiac surgery: a prospective observational study.

BACKGROUND: Depression significantly impacts recovery and return to daily activities in cardiac surgery patients. Assessing and managing depressive symptoms before and after surgery are crucial for improving surgical outcomes and timely return to daily activities, including work. The objectives of this study were to examine differences in patients' depression levels in relation to their return to daily activities in the early post-cardiac surgery period, and to assess predictors of delayed return to daily activities. METHODS: This single-centered study assessed return to independence, social participation, hobbies, and work in 100 cardiac surgical patients at 2 and 6 weeks post-surgery. Associations between depression levels and return to daily activities scores were evaluated. RESULTS: Higher Center for Epidemiologic Studies Depression Scale (CES-D) scores were significantly associated with delayed return to daily activities in all categories at both 2 and 6 weeks post-surgery. Specifically, higher depression score delayed return to independence and social participation at 2 weeks, and delayed return to independence, social participation, and return to work at 6 weeks. CONCLUSION: Elevated depression scores are significantly associated with delayed return to daily activities post-cardiac surgery, indicating the importance of evaluating depression in cardiac surgical patients in the postend stage-operative period.

Clear Yet Crossed: Athletes' Retrospective Reports of Coach Violence.

AIMS: This study aimed at examining coach-athlete violence based on the retrospective reports of adults who had been athletes as children and adolescents; predict variables that contribute to the existence of such violence; describe difficulties that the participants encountered as young athletes following such violence; and reveal the outcomes of such violence on their emotions and behaviors, in the past and present. METHODOLOGY: The applied mixed methods comprised quantitative self-reporting questionnaires and qualitative interviews. The former included 440 participants (mean age 27.6) who had trained for at least one year in a sports union youth department; the latter included 14 participants (aged 23-37). These competitive athletes came from eight branches of sports. The interviews were analyzed based on the Narrative Approach. RESULTS: According to the quantitative study, all participants had experienced coach violence at least once during their career, mainly psychological violence and neglect, followed by physical violence. Sexual violence was least reported. The age of their retirement from sports and the number of coaches that they had had were significant predictors of violence. Thematic analysis of the qualitative interviews resulted in six types of coach-athlete violence: (1) psychological violence; (2) verbal violence; (3) starvation and food fattening; (4) non-proportional punishing; (5) physical violence; and (6) sexual violence. CONCLUSIONS: It is vital that coach-athlete violence is addressed in public discourse, that the topic of young athletes' safety is introduced into coaching education, and that a position holder is nominated to be in charge of such safety in all sports organizations.

Trend of mortality and length of stay in the emergency department following implementation of a centralized sepsis alert system.

Introduction: Sepsis alerts based on laboratory and vital sign criteria were found insufficient to improve patient outcomes. While most early sepsis alerts were implemented into smaller scale operating systems, a centralized new approach may provide more benefits, overcoming alert fatigue, improving deployment of staff and resources, and optimizing the overall management of sepsis. The objective of the study was to assess mortality and length of stay (LOS) trends in emergency department (ED) patients, following the implementation of a centralized and automated sepsis alert system. Methods: The automated sepsis alert system was implemented in 2021 as part of a hospital-wide command and control center. Administrative data from the years 2018 to 2021 were collected. Data included ED visits, in-hospital mortality, triage levels, LOS, and the Canadian Triage and Acuity Scale (CTAS). Results: Mortality rate for patients classified as CTAS I triage level was the lowest in 2021, after the implementation of the automated sepsis alert system, compared to 2020, 2019, and 2018 (p < 0.001). The Kaplan-Meier survival curve revealed that for patients classified as CTAS I triage level, the probability of survival was the highest in 2021, after implementation of the sepsis alert algorithm, compared to previous years (Log Rank, Mantel-Cox, χ²=29.742, p < 0.001). No significant differences in survival rate were observed for other triage levels. Conclusion: Implementing an automated sepsis alert system as part of a command center operation significantly improves mortality rate associated with LOS in the ED for patients in the highest triage level. These findings suggest that a centralized early sepsis alert system has the potential to improve patient outcomes.

A command centre implementation before and during the COVID-19 pandemic in a community hospital.

INTRODUCTION: The objective of the study was to assess the effects of high-reliability system by implementing a command centre (CC) on clinical outcomes in a community hospital before and during COVID-19 pandemic from the year 2016 to 2021. METHODS: A descriptive, retrospective study was conducted at an acute care community hospital. The administrative data included monthly average admissions, intensive care unit (ICU) admissions, average length of stay, total ICU length of stay, and in-hospital mortality. In-hospital acquired events were recorded and defined as one of the following: cardiac arrest, cerebral infarction, respiratory arrest, or sepsis after hospital admissions. A subgroup statistical analysis of patients with in-hospital acquired events was performed. In addition, a subgroup statistical analysis was performed for the department of medicine. RESULTS: The rates of in-hospital acquired events and in-hospital mortality among all admitted patients did not change significantly throughout the years 2016 to 2021. In the subgroup of patients with in-hospital acquired events, the in-hospital mortality rate also did not change during the years of the study, despite the increase in the ICU admissions during the COVID-19 pandemic.Although the in-hospital mortality rate did not increase for all admitted patients, the in-hospital mortality rate increased in the department of medicine. CONCLUSION: Implementation of CC and centralized management systems has the potential to improve quality of care by supporting early identification and real-time management of patients at risk of harm and clinical deterioration, including COVID-19 patients.

A digital exercise and augmented reality training system improved mobility among stroke patients: A randomized control trial.

BACKGROUND: The Selfit system was developed to improve the mobility and gait-related functions of stroke patients by providing digital exercises and augmented reality training system. OBJECTIVE: To evaluate the effects of a digital exercise and augmented reality training system on mobility, gait-related functions and self-efficacy outcomes in stroke patients. METHODS: A randomized control trial was conducted on 25 men and women diagnosed with an early sub-acute stroke. Patients were randomly assigned to either the intervention (N= 11) or the control groups (N= 14). Patients in the intervention group received a digital exercise and augmented reality training using the Selfit system in addition to the standard physical therapy treatment. Patients in the control group were treated with a conventional physical therapy program. Timed Up and Go (TUG) test, 10-meter walk test, the Dynamic Gait Index (DGI), and the Activity-specific Balance Confidence (ABC) scale were completed before and after the intervention. Feasibility and satisfaction among patients and therapists were also assessed after the completion of the study. RESULTS: The intervention group practiced proportionally more time per session than the control group with a mean change of 19.7% following 6 sessions (p= 0.002). The intervention group showed better improvement in post-TUG score compared to the control group (p= 0.04). ABC, DGI, and the 10-meter walk test scores were not significantly different between the groups. Both therapists and participants demonstrated high satisfaction with the Selfit system. CONCLUSION: The findings suggest that Selfit holds promise as an effective intervention for improving mobility and gait-related functions among patients with an early sub-acute stroke as compared to conventional physical therapy treatments.

Nonpharmacological interventions for 'no-option' refractory angina patients.

Refractory angina pectoris (RAP) defined as chronic anginal chest pain because of coronary artery disease (CAD) is a major problem. The increase in the number of patients with RAP in recent years is because of the increasing aging population and improved survival rates among patients with CAD. Management of patients with RAP is often extremely challenging. In this review, we present several interventional approaches for RAP, including device therapies, lifestyle intervention, and cell therapies. Some of these treatments are currently used in the management of RAP, whereas other treatments are under investigation.

Can we improve healthcare with centralized management systems, supported by information technology, predictive analytics, and real-time data?: A review.

This narrative review discusses the effects of implementing command centers, centralized management systems, supported by information technology, predictive analytics, and real-time data, as well as small-scale centralized operating systems, on patient outcomes, operation, care delivery, and resource utilization. Implementations of command centers and small-scale centralized operating systems have led to improvement in 3 areas: integration of both multiple services into the day-to-day operation, communication and coordination, and employment of prediction and early warning system. Additional studies are required to understand the full impact of command centers on the healthcare system.

Pre- and Post-transcatheter Aortic Valve Replacement (TAVR) Serum Mean Platelet Volume Levels and All-Cause Mortality.

BACKGROUND: Among the most frequent complications following transcatheter aortic valve replacement (TAVR) is hemostasis imbalance that presents either as thromboembolic or bleeding. Deviations in platelet count (PC) and mean platelet volume (MPV) are markers of hemostasis imbalance. OBJECTIVES: To determine the predictive value of pre- and post-procedural PC and MPV fL 1-year all-cause mortality in patients who underwent TAVR. METHODS: In this population-based study, we included 236 TAVR patients treated at the Tzafon Medical Center between 1 June 2015 and 31 August 2018. Routine blood samples for serum PC levels and MPV fL were taken just before the TAVR and 24-hour post-TAVR. We used backward regression models to evaluate the predictive value of PC and MPV in all-cause mortality in TAVR patients. RESULTS: In this study cohort, MPV levels 24-hour post-TAVR that were greater than the cohort median of 9 fL (interquartile range 8.5-9.8) were the strongest predictor of 1-year mortality (hazard ratio 1.343, 95% confidence interval 1.059-1.703, P-value 0.015). A statistically significant relationship was seen in the unadjusted regression model as well as after the adjustment for clinical variables. CONCLUSIONS: Serum MPV levels fL 24-hour post-procedure were found to be meaningful markers in predicting 1-year all-cause mortality in patients after TAVR.

Advances in Technology Promote Patient-Centered Care in Cardiac Rehabilitation.

Patient-centered health care (PCC) is a framework of clinical care focused on the patient's individual health care needs. In particular, it emphasizes the development of a partnership between the patient, physician, and healthcare workers to actively involve and empower the patient in their health care decisions. Additionally, PCC goals include ensuring access to care, emotional support, engaging patient support systems, physical comfort, and continuity of care. Technology also provides a platform to engage patients and their families in their care and can be a useful tool to gauge their level of interest, knowledge, and motivations to adequately educate them on the many factors that contribute to their disease, including diet, exercise, medication adherence, psychological support, and early symptom detection. In this article, we summarize the importance of technology in promoting PCC in cardiac rehabilitation and the impact technology may have on the different aspects of patient and physician relationships. Modern technological devices including smartphones, tablets, wearables, and other internet-enabled devices have been shown to help patient-staff communication, cater to patients' individual needs, increase access to health care, and implement aspects of PCC domains.

Does the Initial Screening of Syncope in the Emergency Department and During Hospitalization Adhere to ESC Guidelines?

BACKGROUND: The evaluation of syncope in emergency departments (EDs) and during hospitalization can be ineffective. The European Society of Cardiology (ESC) guidelines were established to perform the evaluation based on risk stratification. OBJECTIVES: To investigate whether the initial screening of syncope adheres to the recent ESC guidelines. METHODS: Patients with syncope who were evaluated in our ED were included in the study and retrospectively classified based on whether they were treated according to ESC guidelines. Patients were divided into two groups according to the ESC guideline risk profile: high risk or low risk. RESULTS: The study included 114 patients (age 50.6 ± 21.9 years, 43% females); 74 (64.9%) had neurally mediated syncope, 11 (9.65%) had cardiac syncope, and 29 (25.45%) had an unknown cause. The low-risk group included 70 patients (61.4%), and the high-risk group included 44 (38.6%). Only 48 patients (42.1%) were evaluated according to the ESC guidelines. In fact, 22 (36.7%) of 60 hospitalizations and 41 (53.2%) of 77 head computed tomography (CT) scans were not mandatory according to guidelines. The rate of unnecessary CT scans (67.3% vs. 28.6%, respectively, P = 0.001) and unnecessary hospitalization (66.7% vs. 6.7%, respectively, P < 0.02) were higher among low-risk patients than high-risk patients. Overall, a higher percentage of high-risk patients were treated according to guidelines compared to low-risk patients (68.2% vs. 25.7% respectively, P < 0.0001). CONCLUSIONS: Most syncope patients, particularly those with a low-risk profile, were not evaluated in accordance with the ESC guidelines.

The Effects of Preoperative Pain Education on Pain Severity in Cardiac Surgery Patients: A Pilot Randomized Control Trial.

BACKGROUND: There is minimal research on the effect of individualized preoperative education on postoperative pain and postoperative pain medication intake. AIM: The study objective was to assess the effect of individually tailored preoperative education on postoperative pain severity, number of pain breakthroughs, and use of pain medication in participants receiving the intervention compared to controls. METHODS: A pilot study with 200 participants was conducted. The experimental group received an informational booklet and discussed their ideas surrounding pain and pain medication with the researcher. Controls received no intervention. Postoperative pain severity was measured by a Numerical Rating System (NRS), which was divided into mild (NRS 1-3), moderate (NRS 4-6), and severe (NRS 7-10). RESULTS: In the participant cohort, 68.8% of participants were male, and the average age was 60.48±10.7. Average postoperative 48-hour cumulative pain scores were lower in those who received the intervention compared to controls; 50.0 (IQR 35.8-60.0) vs. 65 (IQR 51.0-73.0; p < .01) participants who received the intervention had less frequent pain breakthroughs when compared to controls (3.0 [IQR 2.0-5.0] vs. 6.0 [IQR 4.0-8.0; p < .01]). There was no significant difference in the amount of pain medication taken by either group. CONCLUSIONS: Participants who receive individualized preoperative pain education are more likely to have decreased postoperative pain.

The Prognostic Value of Cardiovascular Risk Factors and Laboratory Biomarkers in Predicting 6-Month Outcomes in High-risk Patients with Non-ST Segment Elevation Myocardial Infarction.

BACKGROUND: Acute coronary syndrome (ACS) represents a spectrum of ischemic myocardial disease including unstable angina (UA), non-ST-segment elevation myocardial infarction (NSTEMI), and ST-elevation myocardial infarction (STEMI). Various prognostic scores were developed for patients presenting with NSTEMI-ACS. Among these scores, the GRACE risk score offers the best discriminative performance for prediction of in-hospital and 6-month mortality. However, the GRACE score is limited and cannot be used in several ethnic populations. Moreover, it is not predictive of clinical outcomes other than mortality. OBJECTIVES: To assess the prognostic value of traditional cardiovascular risk factors and laboratory biomarkers in predicting 6-month major adverse cardiac and cerebrovascular events (MACCE), including hospitalization, recurrent percutaneous coronary intervention (PCI), stroke, and cardiovascular mortality in patients with NSTEMI treated with PCI. METHODS: This retrospective study included consecutive patients admitted with an initial diagnosis of NSTEMI to the cardiac intensive care unit (CICU) at the Tzafon Medical Center, Israel, between April 2015 and August 2018 and treated by PCI within 48 hours of admission. RESULTS: A total of 223 consecutive patients with NSTEMI treated by PCI were included in the study. Logarithmebrain natriuretic peptide (LogₑBNP), prior MI, and Hb levels were found to be significant predictors of any first MACCE. Only logₑBNP was found to be an independent predictor of a first MACCE event by multivariate logistic regression analysis. CONCLUSIONS: LogₑBNP is an independent predictor of worse prognosis in patients with NSTEMI. Routine evaluation of BNP levels should be considered in patients admitted with NSTEMI.

Relationships among norepinephrine levels, exercise capacity, and chronotropic responses in heart failure patients.

In heart failure (HF) patients, the pathophysiological mechanisms of severe exercise intolerance and impaired exercise capacity are related to both central and peripheral abnormalities. The central abnormalities in HF patients include impaired cardiac function and chronotropic incompetence (CI). Indeed, CI, the inability to adequately increase heart rate (HR) from rest to exercise often exhibited by HF patients, is related to activation of the sympathetic nervous system (SNS) yielding a rise in circulating norepinephrine (NE). CI may result from downregulation of ß-adrenergic receptors, ß-blocker usage, high baseline HR, or due to a combination of factors. This paper discusses the role of elevated NE in altering chronotropic responses in HF patients and consequently resulting in impaired exercise capacity. We suggest that future research should focus on the potential treatment of CI with rate-adaptive pacing, using a sensor to measure physical activity, without inducing deleterious hormonal activation of the sympathetic system.

Predictors of prolonged hospitalization in modified sternoplasty following postoperative mediastinitis.

BACKGROUND AND AIM: Deep sternal wound infection (DSWI) is a serious complication following cardiac surgery, and demands early intervention as any delay in diagnosis and management may lead to increased morbidity and mortality. DSWI is associated with increased length of hospitalization (LOH) and economic burden in this patient population. The aim of this study was to determine predictors for increased length of hospitalization in patients who underwent the Modified Sternoplasty technique for deep sternal wound infection following cardiac surgery. METHODS: A retrospective study was undertaken on data from patients who underwent the Modified Sternoplasty surgery for DSWI between September 2010 and January 2020. Patients' characteristics that were recorded included medical history, type of the original heart surgery, length of hospitalizations, and risk factors including hyperlipidemia, diabetes mellitus and hypertension, and morbidity and mortality rates following the Modified Sternoplasty. RESULTS: Sixty-eight patients underwent the Modified Sternoplasty surgery with an average length of hospitalization of 24.63 + 22.09 days. Multivariable analysis showed that only gender was considered a predictor of length of hospitalization when controlling for comorbidities, with average length of hospitalization longer for women than men (35.4 vs. 20.9, p = .04). CONCLUSION: The Modified Sternoplasty surgery is a novel surgical technique for managing DSWI complicated by sternal dehiscence with exposed heart and great vessels. Female gender was associated with increased length of hospitalization in our patient cohort, with average length of hospitalization for women almost twice that of males.

Clinical factors and pre-surgical depression scores predict pain intensity in cardiac surgery patients.

BACKGROUND: Severe pain is prevalent in cardiac surgery patients and can increase cardiac complications, morbidity and mortality. The objectives of the study were to assess perioperative pain intensity and to assess predictors of pain post-cardiac surgery, including clinical characteristics and depression. METHODS: A total of 98 cardiac surgery patients were included in the study. Pain intensity was assessed using a Numerical Rating System. Pain was measured one day pre-operatively and recorded daily from Post-operative Day 2 to Day 7. Clinical data were recorded and depression scores were assessed using the Center for Epidemiological Study of Depression (CES-D). RESULTS: Pain intensity increased significantly during hospitalization from pre-operative levels, surging at 2 days post-operatively. Predictors of high pain intensity were high pre-operative CES-D scores, female gender, cardiac function, smoking and high body mass index (BMI). Significantly higher pre-operative CES-D scores were found in patients with severe pain compared to patients with no pain to moderate pain (18.23 ± 1.80 vs 12.84 ± 1.22, p = 0.01 pre-operatively). Patients with severe pain (NRS 7-10) had significantly higher levels of white blood cells (WBC) compared to patients with no pain-moderate pain (NRS 0-6), (p = 0.01). However, CES-D scores were only weakly correlated maximum WBC levels perioperatively. CONCLUSION: Pain intensity significantly increased following surgery, and was associated with depressive symptoms, female sex, cardiac function, BMI, and smoking. These factors may serve as a basis for identification and intervention to help prevent the transition from acute pain to chronic pain.

The routine use of preoperative non-contrast chest computerized tomography and carotid arteries Doppler prior to cardiac surgery.

INTRODUCTION: There is no consensus as to which patients should undergo Non-Contrast Chest Computerized Tomography (NCCCT) and carotid arteries Doppler (CD) prior to cardiac surgery. The objective of this study was to examine whether preoperative imaging modalities provide clinical benefits and a change in surgical strategy. METHODS: We routinely performed NCCCT and CD in all non-urgent cardiac surgery patients. Major NCCCT/CD findings related to cardiovascular findings (aortic calcification/atherosclerosis, carotid artery plaque/stenosis), or other incidental findings (lung kidney, thyroid, adrenal, gastrointestinal sites etc.) were documented. The results were divided into 3 categories: (A) findings requiring both changes in surgical strategy and post-operative evaluation/treatment; (B) findings requiring changes in surgical strategy, but not requiring a specific post-operative evaluation/treatment; (C) findings not requiring changes in surgical strategy but requiring post-operative evaluation/treatment. RESULTS: In this cohort, 93 (18.6%) out of 500 patients had significant cardiac and extra-cardiac findings on NCCCT and/or CD. Among the 93 patients with significant findings, 33.33% (31 patients, 6.2% of all patients) were in group A, 7.5% (7 patients, 1.4% of all patients) were in group B, and 59.14% (55 patients, 11% of all patients) were in group C. Change in surgical strategies included, for example, switching from planned on-pump Coronary Artery Bypass Graft surgery (CABG) to off-pump CABG and performing additional procedures to the originally planned heart surgery. CONCLUSION: Routine preoperative NCCCT and CD evaluation in all non-urgent cardiac surgical patients is an effective measure for uncovering cardiac and extra-cardiac findings prior to surgery.

Unmasking Myocardial Dysfunction in Patients Hospitalized for Community-Acquired Pneumonia Using a 4-Chamber 3-Dimensional Volume/Strain Analysis.

Lower respiratory infection was reported as the most common fatal infectious disease. Community-acquired pneumonia (CAP) and myocardial injury are associated; yet, true prevalence of myocardial injury is probably underestimated. We assessed the rate and severity of myocardial dysfunction in patients with CAP. Admitted patients diagnosed with CAP were prospectively recruited. All the patients had C-reactive protein (CRP), brain natriuretic peptide (BNP), and high-sensitivity cardiac troponin (hs-cTnl) tests added to their routine workup. 2D/3D Doppler echocardiography was done on a Siemens Acuson SC2000 machine ≤ 24 h of diagnosis. 3D datasets were blindly analyzed for 4-chamber volumes/strains using EchobuildR 3D-Volume Analysis prototype software, v3.0 2019, Siemens-Medical Solutions. Volume/strain parameters were correlated with admission clinical and laboratory findings. The cohort included 34 patients, median age 60 years (95% CI 55-72). The cohort included 18 (53%) patients had hypertension, 9 (25%) had diabetes mellitus, 7 (21%) were smokers, 7 (21%) had previous myocardial infarction, 4 (12%) had chronic renal failure, and 1 (3%) was on hemodialysis treatment. 2D/Doppler echocardiography findings showed normal ventricular size/function (LVEF 63 ± 9%), mild LV hypertrophy (104 ± 36 g/m2), and LA enlargement (41 ± 6 mm). 3D volumes/strains suggested bi-atrial and right ventricular dysfunction (global longitudinal strain RVGLS = - 8 ± 4%). Left ventricular strain was normal (LVGLS = - 18 ± 5%) and correlated with BNP (r = 0.40, p = 0.024). The patients with LVGLS > - 17% had higher admission blood pressure and lower SaO2 (144 ± 33 vs. 121 ± 20, systolic, mmHg, p = 0.02, and 89 ± 4 vs. 94 ± 4%, p = 0.006, respectively). hs-cTnl and CRP were not different. Using novel 3D volume/strain software in CAP patients, we demonstrated diffuse global myocardial dysfunction involving several chambers. The patients with worse LV GLS had lower SaO2 and higher blood pressure at presentation. LV GLS correlated with maximal BNP level and did not correlate with inflammation or myocardial damage markers.

The Modified Sternoplasty: A Novel Surgical Technique for Treating Mediastinitis.

Deep sternal wound infection (DSWI) is one of the most complex and devastating complications post cardiac surgery. We present here the modified sternoplasty, a novel surgical technique for treating DSWI post cardiac surgery. The modified sternoplasty includes debridement and sternal refixation via bilateral longitudinal stainless-steel wires that are placed parasternally along the ribs at the midclavicular or anterior axillary line, followed by six to eight horizontal stainless-steel wires that are anchored laterally and directly into the ribs. On top of that solid structure, wound reconstruction is performed by the use of bilateral pectoralis muscle flaps followed by subcutaneous tissue and skin closure. We reported mortality rates and length of hospitalization of patients who underwent the modified sternoplasty. In total, 68 patients underwent the modified sternoplasty. Two of these critically ill patients died (2.9%). The average length of hospitalization from the diagnosis of DSWI was 24.63 ± 22.09 days. The modified sternoplasty for treating DSWI is a more complex surgery compared with other conventional sternoplasty techniques. However, this technique was demonstrated to be more effective, having a lower rate of mortality, and having a length of hospitalization lower than or comparable to other techniques previously reported in the literature.
