Insights
Existing health analytics systems can monitor cardiovascular disease (CVD) preventive care. Evaluation is needed to ensure accurate risk factor measurement and treatment for high-risk individuals.
Area of Science:
- Public Health
- Health Informatics
- Cardiovascular Medicine
Background:
- National guidelines recommend population-level screening and pharmacotherapy for high-risk individuals with cardiovascular disease (CVD).
- A validated system for continuous surveillance of CVD risk factors and treatment is currently lacking.
- This study assessed the utility of an existing health analytics system for CVD surveillance.
Purpose of the Study:
- To evaluate the Primary Sense health analytics system as a tool for cardiovascular disease (CVD) surveillance.
- To identify and rectify errors in data transfer and guideline implementation.
- To report on patient risk stratification and treatment adequacy within a primary health network.
Main Methods:
- The Primary Sense health analytics system was evaluated within a single Primary Health Network.
- Data accuracy was assessed, and errors related to Australian CVD guidelines were identified and corrected.
- Patient numbers in different risk categories and proportions receiving appropriate therapy were determined.
Main Results:
- Data transfer from electronic medical records to Primary Sense was accurate, but guideline implementation errors were found.
- Out of 254,357 individuals, 87,487 (34%) were eligible for CVD risk assessment.
- Among those assessed, 58% of 11,608 high-risk patients (including those with prior CVD or high risk scores) were inadequately treated.
Conclusions:
- Current health analytics systems show potential for monitoring cardiovascular disease (CVD) preventive care.
- System evaluation and refinement are crucial for accurate surveillance of CVD risk factors and treatment.
- These systems can support public health initiatives aimed at improving CVD outcomes.
Aim:
National cardiovascular disease (CVD) risk guidelines recommend population-level screening and pharmacotherapy for high-risk individuals. There is no validated system for surveillance of up-to-date risk factor measurement and treatment. This study evaluated an existing health analytics system as a potential CVD surveillance system.
Method:
In a single Primary Health Network, Primary Sense health analytics system was evaluated as a CVD surveillance system. Errors were identified and corrected. Numbers of patients within different risk groups were identified, and proportions on appropriate therapy were reported.
Results:
Data transfer from general practice electronic medical record systems to Primary Sense was correct, but errors were found regarding implementation of Australian CVD guidelines. Following corrections, out of a population of 254,357 individuals, 87,487 (34%) were eligible for CVD risk assessment. Of these, 4,199 (5%) had pre-existing CVD, 5,124 (6%) were clinically determined high-risk and 42,132 (54%) had no risk score available. Of those with a risk score available, 2,285 (6%) were high-risk. 11,608 patients had prior CVD, clinically determined high-risk or a high CVD risk score and 6,710 (58%) of these were inadequately treated.
Conclusions:
Health analytics systems in current use have the potential to act as surveillance systems to monitor CVD preventive care but require evaluation.
