Impact of Heart Failure Center Program on Cardiac Outcomes in Patients With Heart Failure

Congestive heart failure (CHF) is a major public health problem worldwide. CHF carries a devastating prognosis, which resembles that of some types of malignant cancer. Despite substantial improvements in the management of the disease, the prognosis remains poor especially in advanced stages of the disease. For these patients, self-management plan includes monitoring of symptoms such as fatigue and shortness of breath, daily weighing, and knowing what to do if signs of deterioration appear, and when to report the changes to health. The investigators hypothesize that patients in the heart failure management programs that promote self-management by means of intensive education, edema index-assistance, and telephone follow-up can improve their functional status and quality of life, as well as the biomarkers of CHF, left ventricular systolic function, proteinuria and nutritional status.

Cohort Study on Patient Outcomes, Effectiveness and Cost-effectiveness of Intervention Programmes for DM/HT Patients

Objectives: To determine the outcome trajectories of patients with hypertension (HT) and/or diabetes mellitus (DM), and evaluate the long-term effectiveness and cost-effectiveness of the Risk Assessment and Management Programmes (RAMP) and other primary care services such as Patient Support Call Centre (PSCC) on reducing complications and mortality Design: Population-based cohort study Setting: Hospital Authority (HA) primary care clinics Participants: All patients aged ?18 years with DM or HT managed in HA primary care clinics between 2006 and 2021 Main outcome measures: (1) incidence of DM/HT-related complications (cardiovascular disease, end-stage renal disease, retinopathy, neuropathy and all-cause mortality); (2) service utilization (out-patient clinics, Accident and Emergency and overnight hospitalizations); (3) Incremental cost-effectiveness ratio per complications or all-cause death avoided, and per QALY gained by RAMP or PSCC. Methods: A naturalistic cohort study (maximum 10-year follow-up) and retrospective data extraction from the HA clinical management system (CMS) database will be conducted to identify and correlate outcome trajectories of HT and/or DM patients with personal, service delivery and process of care factors. Outcomes of propensity score matched cohorts who have and have not participated in the programmes will be compared. Multivariable Cox proportional hazards regression and Poisson/negative binomial regression will be conducted to evaluate the effect of RAMP, PSCC and other primary care services on the risk of complications, mortality and service utilization. Empirical costs and effectiveness data will be used to calculate cost-effectiveness from the provider's perspective. Significance: Findings will inform how to optimize service delivery for HT/DM patients in Hong Kong

Policy Responses Against the COVID-19 Pandemic in Latin America

Latin America is one of the worst-hit areas from the COVID-19 pandemic worldwide. Policy responses to COVID-19 in Latin America have sought to reduce viral spread, increase the capacity of the health system response, mitigate negative consequences, and strengthen governance. Few studies have examined the effectiveness of COVID-19 policies in Latin America or explored subnational variation in their effectiveness. In this observational study, the investigators will use a two-stage interrupted time series to estimate the effectiveness of nonpharmaceutical interventions in third-tier subnational units on SARS-COV2 transmission and COVID-19 mortality in Latin America. The investigators will estimate the effects in each local government, and then run a random-effects meta-analysis to obtain pooled effects for each intervention (and combinations of) and heterogeneity estimates. Finally, the investigators will explore potential explanations for the heterogeneity at the local level.

Safety and Effectiveness of NRP for DCD Heart Transplantation

This is a prospective, observational, pilot trial to evaluate the feasibility of heart transplantation using normothermic regional perfusion (NRP) donation after donor circulatory death (DCD). Normothermic regional perfusion utilizes Extracorporeal Membrane Oxygenation (ECMO) or cardiopulmonary bypass to reperfuse the heart and other organs in situ after isolation and ligation of the cerebral vessels. In situ resuscitation of the heart has the added advantage of allowing full hemodynamic and echocardiographic assessment of the donor heart prior to final acceptance for transplantation without the imminent danger of ongoing warm ischemia.

COVID-19 Infections and Mortality in Long-term Care Facilities During the First Wave

The medical charts of all COVID-19 cases (n=1200) from 17 long-term care facilities in Montreal, Canada will be reviewed, to compare patients who survived to patients who did not survive. Through multilevel logistic regression, the risk of death will be estimated for institutional predictors of mortality, while controlling for individual risk factors. Individual covariates include clinical features (age, sex, Charlston comorbidity index, SMAF autonomy score, severity criteria) and medical treatments (IV fluids, anticoagulation, oxygen, regular opiates, corticosteroids). Aggregate covariates include epidemiological data (attack rates, timing of outbreak) and institutional characteristics (number of beds, air exchange per hour, presence of a dedicated COVID-19 unit at the time of outbreak, staff compliance to infection control measures, staff infection rates, understaffing, proportion of semi-private rooms, proportion of wandering wards and other special units).

Preserving Compassionate End of Life Care in the Pandemic

Compassionate and humanistic care for patients dying in the hospital has been especially challenging during the pandemic. Family presence is restricted, maximal barrier precautions are advised, and personal protective equipment must be preserved. This research examines the impact of adaptations to compassionate approaches to end of life care in a single center. The 3 Wishes Project (3WP) was created to promote the connections between patients, family members, and clinicians that are foundational to empathic end-of-life care. It provides a scaffold for discussions about preferences and values at the end of life and leads to acts of compassion that arise from soliciting and implementing wishes that honour the dying patient. It is partnered with the Footprints Project, which is an initiative encouraging staff to learn more about each patient. In a previous multi-center evaluation, the authors reported how the 3 Wishes Project is valuable, transferable, affordable and sustainable. During the pandemic, end of life care, facilitated by the 3 Wishes Project and Footprints Project, will be adapted to accommodate reduced family visiting and requirements to preserve PPE. The objective of this study is to evaluate whether the adapted 3 Wishes Project continues to be feasible and valuable during the pandemic, and determine how it influences the experiences of clinicians caring for patients dying during the pandemic.

Association of Endothelial Function and Clinical Outcomes in Subjects Admitted to Chest Pain Unit

It is recognized that endothelial dysfunction is a major factor contributing to the atherogenic process. Abnormal function of the endothelium is detectable prior to obvious intimal lesions in patients with risk factors for atherosclerosis. Endothelial dysfunction is a systemic disorder and a key variable in the pathogenesis of atherosclerosis and its complications. Measurement of peripheral vasodilator response with fingertip peripheral arterial tonometry (PAT) technology (EndoPAT; Itamar Medical, Caesarea, Israel) is emerging as a useful method for assessing vascular function. EndoPAT may be a potential valid test increasing the accuracy, sensitivity and specificity for detection of subjects to chest pain unit (CPU) with chest pain but no obvious coronary artery disease (CAD). This is a relatively fast non-invasive bedside test, relatively low-cost and has no side effects. Therefore, the primary objective of the study is to test the hypothesis that abnormal endothelial function as assessed by EndoPAT testing will increase the prediction of the short (in-hospital) and long-term (1-year) outcome of patients presenting to the chest pain unit.

Partial Breast Versus no Irradiation for Women With Early Breast Cancer

All early breast cancer patients are offered adjuvant breast radiation therapy (RT) after breast conserving surgery for an early breast cancer. Breast cancer is heterogeneous, and selected patients have a very low gain from RT, whilst they still have risk of acute and late side effects from RT. This trial will try identify selection criteria for low risk breast cancer patients who can safely omit adjuvant RT without unacceptable high risk of local failure.

Risk Calculators Validation for Elective Major General Surgery

Nowadays, over 300 million surgical operations take place every year worldwide, which increase at a rate of 33.6% comparing data from 2005 to 2013. According to Surgical Outcomes Monitoring and Improvement Program (SOMIP) reports, which is an Hospital Authority-wide (HA-wide) audit on postoperative outcomes, a growth in major and ultra-major operations performed in our locality is also observed between 2008 and 2016, which leads to an increasing demand of high dependency and intensive care in the postoperative period. With the advancement in surgical technology, increasing surgical complexity and aging population have raised concerns towards perioperative costs and postoperative complications. Therefore, there is a need of an objective tool for risk stratification, which would be useful to guide clinical decision in terms of the magnitude of operation, level of intraoperative monitoring and postoperative placement plan. Various risk scoring systems have been developed nowadays and each has its own limitations. As nowadays, the calculated risk score is commonly used in shared decision making process with patient and among the perioperative team. Risk calculation solely based on preoperative parameters will be more practical for daily clinical use. Therefore, in this study, the investigators would like to validate the postoperative mortality prediction with the risk calculators that are established merely using preoperative variables. Hopefully this would guide the future risk stratification in patients undergoing elective major surgical operation.
