Initial treatment of hypertension: a questionnaire survey
Insights
Despite debates on hypertension management, most physicians still prefer diuretics or beta-blockers for initial treatment. This standard stepped care (SC) approach remains common for mild to moderate hypertension.
Area of Science:
- Cardiology
- Internal Medicine
- Pharmacology
Background:
- The stepped care (SC) approach has long been standard for hypertension management.
- Recent safety concerns regarding diuretics and new antihypertensive drugs have questioned SC's continued use.
- The impact of this debate on initial drug selection for mild to moderate hypertension is unclear.
Purpose of the Study:
- To assess the current initial drug selection practices for mild to moderate hypertension among different physician groups.
- To determine if recent criticisms of the stepped care approach have influenced prescribing habits.
Main Methods:
- Four patient vignettes representing mild to moderate hypertension were developed.
- Three physician groups (house staff, faculty, private practitioners) were surveyed on initial treatment choices.
- Ninety-five physicians responded to the vignette-based treatment scenarios.
Main Results:
- Of physicians selecting a drug therapy (85.9%), 81.2% chose either a diuretic or a beta-blocker, consistent with the SC regimen.
- Physician groups differed more in decisions to treat than in drug choice.
- House officers showed a slight tendency towards using more beta blockers and non-SC drugs.
Conclusions:
- Many physicians remain comfortable using diuretics or beta-blocking agents as initial therapy for mild to moderate hypertension.
- The traditional stepped care approach persists despite ongoing debate and criticism.
- Physician prescribing patterns for initial hypertension management show adherence to established SC guidelines.
Abstract:
The "stepped care" (SC) approach to the management of hypertension has been the standard of care for many years. Recently, concerns about safety of diuretics, coupled with the development of a variety of new antihypertensive agents, have led to questions about the continued use of SC. It is unclear what effect this continuing debate has had on the initial selection of drugs to treat mild to moderate hypertension. We developed four vignettes intended to represent typical patients with mild to moderate hypertension and asked three groups of physicians (house staff, faculty physicians, and private practitioners) how they would initially treat the patients represented by the vignettes. Ninety-five physicians responded. Among the physicians who chose a drug therapy for a vignette (85.9% of total responses), 81.2% selected either a diuretic or a beta-blocking agent, the standard SC regimen. Differences among the groups of physicians dealt with decisions to treat rather than choice of drugs, although house officers tended to use slightly more beta blockers and non-SC drugs. In spite of recent criticism of the SC approach, many physicians are comfortable with the use of diuretics or beta-blocking agents as the initial treatment of mild to moderate hypertension.
