Cost-Effectiveness of Antihypertensive Deprescribing in Primary Care: a Markov Modelling Study Using Data From the OPTiMISE Trial

Deprescribing Hypertension Medication in Older Adults: Can It Lower Drug Burden Without Causing Harm?

Due to the high prevalence of older individuals with multiple morbidities, polypharmacy, and exposed to unnecessary or inappropriate treatments that can cause potentially serious adverse effects, better medication management should be an objective of all health professionals. This is particularly important in older patients with hypertension. Antihypertensive deprescribing and non-pharmacological strategies have been disseminated as viable and safe alternatives for improving the quality of care for hypertension in the older population.

Epidemiology of Hypertension in Older Adults

The exact definition of hypertension in older adults has changed over the decades, but the benefits of strict blood pressure control across the life span are being increasingly recognized by professional societies and guideline committees. This article discusses the prevalence of hypertension in older adults and describes the associations between hypertension and both clinical and nonclinical morbidity in that population.

The therapeutic concordance approach reduces adverse drug reactions in patients with resistant hypertension

Background

Adverse drug reactions (ADRs) remain among the leading causes of therapy-resistant hypertension (TRH) and uncontrolled blood pressure (BP). We have recently reported beneficial results in BP control in patients with TRH adopting an innovative approach, defined as therapeutic concordance, in which trained physicians and pharmacists reach a concordance with patients to make them more involved in the therapeutic decision-making process.

Methods

The main scope of this study was to investigate whether the therapeutic concordance approach could lead to a reduction in ADR occurrence in TRH patients. The study was performed in a large population of hypertensive subjects of the Campania Salute Network in Italy (ClinicalTrials.gov Identifier: NCT02211365).

Results

We enrolled 4,943 patients who were firstly followed-up for 77.64 ± 34.44 months, allowing us to identify 564 subjects with TRH. Then, 282 of these patients agreed to participate in an investigation to test the impact of the therapeutic concordance approach on ADRs. At the end of this investigation, which had a follow-up of 91.91 ± 54.7 months, 213 patients (75.5%) remained uncontrolled while 69 patients (24.5%, p < 0.0001) reached an optimal BP control. Strikingly, during the first follow-up, patients had complained of a total of 194 ADRs, with an occurrence rate of 68.1% and the therapeutic concordance approach significantly reduced ADRs to 72 (25.5%).

Conclusion

Our findings indicate that the therapeutic concordance approach significantly reduces ADRs in TRH patients.

Antihypertensive Deprescribing in Older Adults: a Practical Guide

PURPOSE OF REVIEW

To summarise evidence on both appropriate and inappropriate antihypertensive drug withdrawal.

RECENT FINDINGS

Deprescribing should be attempted in the following steps: (1) identify patients with several comorbidities and significant functional decline, i.e. people at higher risk for negative outcomes related to polypharmacy and lower blood pressure; (2) check blood pressure; (3) identify candidate drugs for deprescribing; (4) withdraw medications at 4-week intervals; (5) monitor blood pressure and check for adverse events. Although evidence is accumulating regarding short-term outcomes of antihypertensive deprescribing, long-term effects remain unclear. The limited evidence for antihypertensive deprescribing means that it should not be routinely attempted, unless in response to specific adverse events or following discussions between physicians and patients about the uncertain benefits and harms of the treatment.

PERSPECTIVES

Clinical controlled trials are needed to examine the long-term effects of deprescribing in older subjects, especially in those with comorbidities, and significant functional decline.
