Insights
UK doctors often prescribed single-drug therapy for hypertension, even for high-risk patients. Combination therapy showed benefits for high-risk individuals, but they were less likely to receive it, suggesting a gap in hypertension treatment protocols.
Area of Science:
- Cardiology
- General Practice
- Pharmacology
Background:
- Hypertension management guidelines recommend tailored treatment strategies.
- Understanding UK practice patterns for newly diagnosed hypertension is crucial for optimizing patient care.
- Subgroup analysis can reveal disparities in treatment protocols for high-risk populations.
Purpose of the Study:
- To examine UK practice patterns in treating newly diagnosed hypertension.
- To determine if high-risk patient subgroups are more or less likely to follow specific therapeutic protocols.
- To assess if high-risk patients are more or less likely to reach blood pressure goals.
Main Methods:
- Retrospective cohort study utilizing The Health Improvement Network (THIN) database.
- Analysis of 48,131 adult patients with essential hypertension diagnosed between 2008-2010.
- Multivariable logistic regression to assess odds of receiving specific therapies and achieving blood pressure control.
Main Results:
- 95.8% of patients were initiated on single-drug therapy for hypertension.
- High-risk patients were surprisingly less likely to receive combination therapy compared to low-risk patients.
- Combination therapy demonstrated a statistically significant benefit for high-risk patients in achieving blood pressure control.
Conclusions:
- Combination therapy may be indicated for a significant proportion (60.6%) of high-risk hypertension patients.
- UK practice patterns appear to align with the 2006 NICE guideline recommending initial single-drug therapy.
- Further investigation into optimizing combination therapy use for high-risk hypertension patients is warranted.
Objective:
To examine the UK practice patterns in treating newly diagnosed hypertension and to determine whether subgroups of high-risk patients are more or less likely to follow particular therapeutic protocols and to reach blood pressure goals.
Design:
Retrospective cohort study.
Setting:
This study examined adults in The Health Improvement Network (THIN) UK general practice medical records database who were initiated on medication for hypertension.
Participants:
48 131 patients with essential hypertension diagnosed between 2008 and 2010 who were registered with a participating practice for a minimum of 13 months prior to, and 6 months following, initiation of therapy. We excluded patients with gestational hypertension or secondary hypertension. Patients were classified into risk groups based on blood pressure readings and comorbid conditions.
Primary And Secondary Outcome Measures:
Odds of receiving single versus fixed or free-drug combination therapy and odds of achieving blood pressure control were assessed using multivariable logistic regression.
Results:
The vast majority of patients (95.8%) were initiated on single drug therapy. Patients with high cardiovascular risk (patients with grade 2-3 hypertension or those with high normal/grade 1 hypertension plus at least one cardiovascular condition pretreatment) had a statistically significant benefit of starting immediately on combination therapy when blood pressure control was the desired goal (OR: 1.23; 95% CI: 1.06 to 1.42) but, surprisingly, were less likely than patients with no risk factors to receive combination therapy (OR: 0.53; 95% CI: 0.47 to 0.59).
Conclusions:
Our results suggest that combination therapy may be indicated for patients with high cardiovascular risk, who accounted for 60.6% of our study population. The National Institute for Health and Care Excellence guideline CG34 of 2006 (in effect during the study period) recommended starting with single drug class therapy for most patients, and this advice does seem to have been followed even in cases where a more aggressive approach might have been considered.
