Hypertension management in general practice
1Department of Social Medicine, University of Bristol, England.
Insights
General practitioners (GPs) and consultants show varied approaches to managing hypertension. Many older physicians hold potentially unrealistic expectations regarding the benefits of treating high blood pressure.
Area of Science:
- Cardiology
- General Practice
- Public Health
Background:
- Hypertension management in primary care is crucial for cardiovascular disease prevention.
- Understanding physician perspectives on hypertension treatment is essential for guideline adherence and patient outcomes.
Purpose of the Study:
- To compare the perspectives of general practitioners (GPs) and consultant physicians on the management of hypertensive patients in primary care.
- To identify discrepancies in treatment thresholds, investigation strategies, and perceived effectiveness of hypertension management.
Main Methods:
- A postal questionnaire survey was distributed to 542 GPs and 64 consultant physicians.
- Response rates were 60% for GPs (n=325) and 70% for consultants (n=45).
- Data collected focused on treatment decisions for hypothetical patient scenarios and views on investigations and outcomes.
Main Results:
- Most GPs adhere to guidelines for initiating drug treatment in a 40-year-old man, while many consultants and older GPs favor earlier intervention.
- A higher percentage of consultants (87%) than GPs (75%) would recommend drug treatment for a 70-year-old woman with elevated blood pressure (180/100 mmHg).
- Consultants expected GPs to order more tests than GPs reported performing, though investigation types were similar except for imaging. Discrepancies noted in blood pressure monitoring frequency and perceived GP ability to prevent cardiovascular events.
Conclusions:
- Significant differences exist in hypertension management approaches between GPs and consultants, particularly concerning treatment initiation thresholds.
- Some older GPs and consultants may possess overly optimistic expectations regarding the impact of hypertension treatment on preventing cardiovascular events.
- Further research and education may be needed to align hypertension management practices and expectations across different physician groups.
Abstract:
The views of 542 general practitioners (GPs) and 64 consultant physicians about the management of patients with hypertension in general practice were sought by postal questionnaire. 325 (60%) of the GPs and 45 (70%) of the consultant physicians completed the questionnaire. For a 40-year-old man with no other cardiovascular risk factors most general practitioners would intervene with drugs at blood pressure levels specified in published guidelines, whereas many local consultants and older GPs would consider drug treatment at lower levels. About 75% of GPs, compared with 87% of consultants, would suggest drug treatment in a woman of 70 years with a BP of 180/100 mmHg. Although consultants tended to expect GPs to order more tests when investigating a patient with hypertension than the GPs actually did, both GPs and consultants would order similar types of investigations apart from imaging. Consultants had different expectations about the frequency with which general practitioners should record patients' blood pressure and the GPs' ability to prevent cardiovascular events in hypertensive patients. Many older GPs and consultants seem to have unrealistic expectations of the value of treating patients with hypertension.
