Evaluation of the Effectiveness of the Mobile Application on Adherence of Patients With Arterial Hypertension.

BACKGROUND

An assessment of the level of adherence of patients diagnosed with hypertension to therapy has not been conducted in Central Asia yet. It includes the lack the information on the impact of digital technologies on hypertension management.

OBJECTIVE

The study aimed at the evaluation of the effect of using a mobile application on adherence to therapy in patients with diagnosed arterial hypertension.

METHODS

A multi-centre randomized controlled study was conducted on 517 patients with diagnosed arterial hypertension (in the out-patient clinic, Almaty, Kazakhstan). Patients were randomly assigned to intervention (IG) and control (CG) groups. IG patients used a mobile application, which allowed creating an individual schedule for taking medications, including visual and audio notifications. The assessment of adherence to antihypertensive treatment was carried out using the Lebanese Medication Adherence Scale-14 (LMAS-14), consisting of 14 items. Data were collected before therapy (T1), 3 months (T2), 6 months (T3) and 12 months (T4) followed the first dose. Adherence was assessed on 101 patients in the CG group and 165 respondents in the IG group.

RESULTS

In the period T1 in both groups CG and IG, a moderate adherence to treatment was recorded with indices equal to 35.9 ± 1.2 and 35.9 ± 1.3, respectively (p ≤ 0.05). A decrease in adherence in the CG group was determined after 3 months (35.9 ± 1.2) (p ≤ 0.05) and six months later (36.5 ± 3.2) in comparison with relatively high adherence among respondents in the IG group in periods T2 (39.5 ± 1.2) and T3 (40.5 ± 1.2) (p ≤ 0.001). After 12 months (T4) on the adherence scale in patients who used the mobile application "MyTherapy" (IG), despite a slight decrease in scores, the results were relatively higher (40.3 ± 1.3) compared with the CG group (33.6 ± 1.9) (p ≤ 0.001).

CONCLUSION

The analysis of adherence of patients with primary health care in Almaty (Kazakhstan) with chronic arterial hypertension showed the effectiveness of using the 'MyTherapy' mobile application in increasing patient adherence. The obtained data on the positive effect of the use of digital technologies require further research to assess the possibility of wider implementation in healthcare.
