Podcast: Self-management strategies in inflammatory arthritis

3rd December 2021

Hospital Healthcare Europe had the pleasure of hearing from Elena Nikiphorou (Consultant Rheumatologist and Adjunct Senior Lecturer at Kings College London, UK) on the recent EULAR guidelines and the importance of self-management strategies in supporting the patient with inflammatory arthritis

Hypertension self-management successful with mobile technology

21st October 2021

Hypertension self-management can be successfully achieved over a three year period through harnessing the support of mobile technology

The use of mobile technology can support hypertension self-management in patients with the condition, according to the findings of a three-year study by a group from the Department of Epidemiology & Biostatistics, University of California, California, US. Hypertension is a global problem with the World Health Organisation (WHO) estimating that it affects 1.28 billion adults aged 30-79 years. However, perhaps of greater concern, is the WHO statistic that only 1 in 5 adults (21%) with hypertension have their condition under control.

Although self-monitoring can lead to reductions in blood pressure (BP) over and above usual care, a 2017 systematic review concluded that self-monitoring alone is not associated with lower BP or better control but that it requires co-interventions such as education or lifestyle counselling, to achieve clinically significant reductions which persist for at least 12 months. The use of mobile technology in the form of smartphone health apps, have been suggested a method to enable effective self-management of hypertension. Yet despite this potential role, a 2018 review of such apps concluded that although available studies do suggest a reduction in blood pressure among those using health apps, the conclusion should be interpreted with caution, since many studies were at high risk of bias.

Given the high risk of bias and the importance of co-interventions, the Californian team used a smartphone app in conjunction with BP monitoring that included digital-based coaching to help support hypertension self-management. Participants were US adults with elevated BP recruited through an employer-based health plan. Blood pressure was measured using an FDA approved Bluetooth-enabled monitor paired with the smartphone app which also allowed participants to track their weight and levels of physical activity. The app included medication reminders and coaching to drive lifestyle changes based on usage patterns to personalise the advice. At baseline, participants were categorised in terms of their systolic BP as: normal and < 120 mmHg; systolic between 120 and 129 mmHg; systolic between 130 and 139 (stage 1 hypertension) and finally a systolic > 140 mmHg (stage 2 hypertension). Blood pressure measurements (both systolic and diastolic) were evaluated in the first week (week 0) and then several times up to weeks 148 to 163.

Findings

A total of 28,189 individuals with a median age of 51 years (59.6% male) were included in the hypertension self-management study. After 3 years, median systolic blood pressure was reduced in 53.7% of those with a systolic BP between 120 and 129 mmHg, 75.3% of those with stage 1 hypertension and in 84.4% of those with stage 2 hypertension. Similarly, after 3 years, the mean reductions in diastolic BP were -4.4 mmHg, -6.8 mmHg and -11.6 mmHg respectively.

A subgroup of 3,229 participants recorded their body mass index (BMI) and for each unit reduction in BMI, there was a 0.74 mmHg decrease in systolic BP. Similarly, among 590 individuals who recorded their physical activity, for each 1000-step increase per day, there was a 0.8 mmHg lower systolic BP (P = 0.03).

The authors concluded that their hypertension self-management program supported by mobile technology, achieved long-term control of BP, suggesting that this approach may be useful for BP monitoring and control.
