An evaluation of the impact of aggressive hypertension, diabetes and smoking cessation management on CVD outcomes at the population level: a dynamic simulation analysis

Abstract

Background Evidence from randomized control trials suggest that coupled with smoking cessation interventions, CVD events can be reduced significantly if hypertension and diabetes patients are properly managed, raising practical what-if questions at the population level. This research aims to develop a dynamic simulation model using the systems modelling methodology of system dynamics, to evaluate the medium to long-term impact of hypertension and diabetes management, as well as smoking cessation intervention on CVD events, CVD deaths and post-CVD population. Methods The systems modelling methodology of system dynamics was used to develop a simulation model to evaluate the impact of aggressive hypertension, diabetes and smoking cessation management on CVD outcomes at the population level. Result The insights from this research suggest that despite that at the individual level, hypertension management is associated with the highest risk reduction for CVD (50%) compared to diabetes and smoking (20%) and is also the most prevalent risk factor, at the population level, diabetes management interventions are projected to have higher impact on reducing CVD events compared to hypertension management or smoking cessation interventions. However, a combined intervention of diabetes and hypertension management, as well as smoking cessation has the most impact on CVD outcomes. Conclusion Due to aging population and the increasing prevalence of chronic conditions in Singapore, the number of CVD events in Singapore is projected to rise significantly in the near future—hence the need for proactive planning to implement needed interventions. Findings from this research suggest that CVD events and its associated deaths and disabilities could be reduced significantly if diabetes and hypertension patients are aggressively managed.

The Benefits of Physical Activity on Indicators of Cardiovascular Risk in Community-Dwelling Older Adults with Hypertension in Korea: A Longitudinal Study

“…These results support previous research indicating that regular physical activity can lower BP and blood glucose and reduce CVD risks [11,[18][19][20]. Oxygen, supplied to the body during physical activity, strengthens the muscles of the cardiovascular system and is effective in improving peripheral vascular resistance associated with CVD indicators, such as hypertension and diabetes [21].…”

The Impact of Sedentary Behavior and Self-Rated Health on Cardiovascular Disease and Cancer among South Korean Elderly Persons Using the Korea National Health and Nutrition Examination Survey (KNHANES) 2014–2018 Data

“…CVD was also associated with waist circumference, diabetes mellitus, hypertension, and dyslipidemia. Chronic diseases (e.g., diabetes mellitus, hypertension, dyslipidemia) are well-known risk factors for CVD, and emphasis is placed on their management worldwide to improve their outcomes [20,21]. Reducing SB is essential for the management of CVD and chronic diseases in older adults, especially hypertension, diabetes, and dyslipidemia, at a personal and national level [20,22].…”

Evaluating the impact of upstream and downstream interventions on chronic kidney disease and dialysis care: a simulation analysis

“…The system dynamics methodology has been used effectively to address dynamically complex issues in healthcare (Ansah et al ., 2014; Ghaffarzadegan et al ., 2016; Abas et al ., 2017) and health policy (Sabounchi et al ., 2014). Studies on the application of system dynamics to chronic diseases have been reported (Homer et al ., 2004; Jones et al ., 2006; Ansah et al ., 2019); however, few have focused on chronic kidney disease. A systematic review by Darabi and Hosseinichimeh (2020) found only three system dynamics studies that focused on CKD, indicating the limited number of system dynamics studies on CKD.…”
