The Impact of Nurse-Led Cardiac Rehabilitation on Quality of Life and Biophysiological Parameters in Patients With Heart Failure: A Randomized Clinical Trial.

BACKGROUND: Cardiovascular diseases are the leading cause of mortality in the Indian subcontinent, accounting for 38% of deaths annually. One cardiovascular disease in particular, heart failure, is a growing public health problem both in India and worldwide. PURPOSE: Heart failure is a chronic, progressive disease with increasing rates of incidence and prevalence. This study was conducted to determine the influence of a nurse-led cardiac rehabilitation program on quality of life and biophysiological parameters in patients with chronic heart failure. In this study, it was hypothesized that participants in the cardiac rehabilitation program would report significantly more-positive changes in quality of life and biophysiological parameters than their peers who did not participate in this program. METHODS: In this randomized controlled trial, the participants were patients with chronic heart failure who had been admitted to a tertiary care hospital in India. The participants assigned to the intervention group received both nurse-led cardiac rehabilitation and routine care. In addition, intervention group participants received a booklet on cardiac rehabilitation, Healthy Way to Healthy Heart, at discharge and fortnightly telephone reminders about good cardiac rehabilitation practices. A standard questionnaire was used to collect targeted information on participants' general and disease-specific quality of life at 1 and 3 months postintervention. Biophysiological parameters such as body mass index, blood pressure, and serum cholesterol values were also measured. RESULTS: Two thirds of the participants in each group (65% in the intervention group and 66% in the control group) were between 51 and 70 years old. The mean score for the mental component summary of generic quality of life steadily decreased in the control group and steadily increased in the intervention group at the first and second posttests. CONCLUSIONS/IMPLICATIONS FOR PRACTICE: Nurses working in cardiology units play a pivotal role in educating and managing the health status of patients with heart failure. Providing cardiac rehabilitation to patients with heart failure benefits the quality of life of these patients. Nurses working in cardiology units should encourage patients with heart failure to practice cardiac rehabilitation for a longer period to further improve their quality of life.

Validation of Predicting Hyperglycemic Crisis Death Score: A Risk Stratification Tool for Appropriate Disposition of Hyperglycemic Crisis Patients from the Emergency Department.

CONTEXT: Predicting hyperglycemic crisis death (PHD) score is a simple, rapid tool with six independent mortality predictors to calculate 30-day mortality and appropriately dispose patients to Intensive Care Unit (ICU) or ward. AIMS: This study aimed at validating the efficiency of PHD score as a decision rule for prognosticating 30-day mortality and classifying hyperglycemic crisis patients for appropriate disposition from the emergency department (ED). MATERIALS AND METHODS: This is a prospective, observational study done in the ED of a teaching hospital over 14 months. All patients aged >18 years and who met the criteria of hyperglycemic crisis were enrolled. Thirty-day mortality of six independent predictors was the primary end point. Using PHD, risk scores were calculated and patients were disposed as per physician's clinical judgment. Finally, the treating physician's decision and PHD score disposition were compared and the efficiency of PHD in predicting 30-day mortality was analyzed. Multiple logistic regression models were used for analysis. Receiver operating characteristic curve was drawn, and area under the curve along with sensitivity, specificity, positive predictive value, and negative predictive value was analyzed. P < 0.05 was considered statistically significant. RESULTS: A total of 133 patients were included. On applying PHD score, 69, 39, and 25 patients were in the low-, intermediate-, and high-risk groups, respectively, with a mortality rate of 5.8%, 20.5%, and 56%, respectively. On comparing physician disposition with PHD score, an increasing mortality was noticed in ICU, and PHD showed equal weight in risk stratification and appropriate disposition of patients. CONCLUSION: In adult patients with hyperglycemic crisis, PHD score is validated as a straightforward, prompt tool for predicting 30-day mortality and aids in disposition. The mortality rate in the PHD score Model II was similar to the physician's clinical decision.
