The purpose of this pragmatic multi-centre, cluster randomized controlled trial is to test the effectiveness of tailored SMS-text message support combined with an information-motivation-behavioral skills (IMB) model-based initiation of medication in helping outpatient care patients with hypertension to achieve blood pressure target and to enhance medication adherence.
Background
Usual blood pressure is strongly related to vascular and overall mortality and high blood pressure is globally the leading risk factor for cardiovascular and related diseases. It is also well established that pharmacologic blood pressure reduction prevents cardiovascular events and deaths in persons with hypertension.
Today's physicians have plenty of knowledge and multiple effective and safety tools to treat hypertension but still majority of patients with antihypertensive medication do not achieve the blood pressure target. Poor medication adherence has been widely accepted to be the most important factor in failing to control hypertension and even 50% of hypertensive patients quit the antihypertensive medication during the first year of medication.
Numerous interventions to enhance medication adherence have been developed but even though, an intervention effective, simple and low cost enough to be carried out wide-scale in non-research settings is still to be found.
Objectives
To test whether a tailored SMS-text message support combined with an IMB model-based initiation of medication will increase the proportion of patients achieving the systolic blood pressure target at 12-month follow-up compared to usual care.
Additional objectives include investigating whether the intervention have effect on
And, besides
Detecting the participants who especially benefit from intervention
Study design
Pragmatic randomized controlled multicenter trial. The eight study centers are grouped to comparable pairs and randomized to function as intervention and control sites (2-cluster design).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Usual care (Reference group) | Active Comparator | Treatment is leaded by treating physician according to national guide lines with no study-specific medication or clinical appointment protocol. |
|
| An IMB model-based initiation of medication | Experimental | In addition to usual care, participants allocated to intervention group will receive An IMB model-based initiation of medication i.e. a nine-point check list to be fulfilled by physician and patient together when ordering the antihypertensive medication for the first time |
|
| Tailored SMS-text message support | Experimental | Tailored SMS-text message support for the first 12 months of medication. At the beginning (2 weeks), text messages are send on daily basis and focused on medications-reminders and coping with potential side-effects of medication. After that, text messages will be sent less often and the focus will change to keeping up with medication and reminding of importance of performing adequate home BP self-monitoring, achieving the BP target and attending clinical appointments. |

| Measure | Description | Time Frame |
|---|---|---|
| The proportion of patients achieving the systolic blood pressure target at 12-month follow-up | The proportion of patients (%) achieving systolic office blood pressure (BP) target (<140 mmHg) and home BP target (<135 mmHg) are both analyzed separately using mixed effects model. Both office BP and home BP are measured with a validated blood pressure monitoring device (Microlife Watch BP Home A or Microlife Watch BP Home N) after appropriate rest from the left arm with an appropriately sized semi-rigid conical cuff. Office BP is the mean of three measurements separated by 15 seconds. Home BP is measured correspondingly three times in the morning and in the evening on 7 consecutive days at 12 months. Home BP is the mean of all available measurements. | 12 months from baseline |
| Measure | Description | Time Frame |

| Measured medication adherence | Medication adherence is assessed by pharmacy refill data and by self-report strategy (Morisky Medication Adherence Scale, MMAS-8). Tresholds for good adherence are correspondingly (i) Medication possession ratio (MPR) 80 % or more and (ii) MMAS-8 with a score of 6 or more. Both are analyzed separately using generalized mixed effects model. Besides, medication adherence is analyzed as follows:

| Measure | Description | Time Frame |

| The quality of IMB model-based structured initiation of medication for screening of non-compliant patients | IMB model-based initiation of medication (check list for the initiation) includes a 10-grade numeric rating scale asking the participant to evaluate the necessity of antihypertensive medication at individual level. Our hypothesis is that the evaluated necessity of antihypertensive medication is related to medication adherence and achieving blood pressure target. |

| Change in systolic and diastolic blood pressure | Both office BP and home BP are measured with a validated blood pressure monitoring device (Microlife Watch BP Home A or Microlife Watch BP Home N) after appropriate rest from the left arm with an appropriately sized semi-rigid conical cuff. Office BP is the mean of three measurements separated by 15 seconds. Home BP is measured correspondingly three times in the morning and evening on 7 consecutive days at 12 months. Home BP is the mean of all available measurements. Change in office BP and home BP are both analyzed separately using generalized mixed effects model. Change in systolic and diastolic blood pressure are as well both analyzed separately using generalized mixed effects model. | 12 months from baseline |
| Hypertension-related use of health care services | Hypertension-related use of health care services (outpatient care and hospital admissions) is assessed by examining participants' electronic health records and with a questionnaire regarding the use of health services other than study centers. Proportion of scheduled clinic appointments attended is also analyzed. | 0-12 months from baseline |
| Perceived quality of life | Perceived quality of life is assessed by EQ-5D-5L questionnaire | baseline and 12 months from baseline |
| The proportion of participants knowing the adequate home BP target | Knowing the target is assessed by questionnaire at baseline and at 12 months. The results are divided into three groups: (i) knows the adequate target (ii) knows the target but it is not adequate (iii) do not know the target. The target is considered adequate if it differs less than 5/3 mmHg from the Finnish national guide lines for treating hypertension (Office BP target <140/90 mmHg except diabetics <140/80 mmHg. Home BP target <135/85 mmHg except diabetics <135/75 mmHg) | baseline and 12 months from baseline |
| The proportion of patients whose BP target is adequately set | Setting the target is assessed by examining the electric health record at 12 months The results are divided into three groups: (i) written target is set and adequate (ii) written target is set but not adequate and (iii) written target is not set. The target is considered adequate if it differs less than 5/3 mmHg from the national guide lines for treating hypertension (Office BP target <140/90 mmHg except diabetics <140/80 mmHg. Home BP target <135/85 mmHg except diabetics <135/75 mmHg) | 12 months from baseline |
| The quality and quantity of self-monitored blood pressure | The quality and quantity of self-monitored blood pressure measurements made prior to follow-up period is assessed first at base line. All participants are then equipped with a validated blood pressure monitoring device (Microlife Watch BP Home A or Microlife Watch BP Home N) with a memory space up to 250 measurements. The quality and quantity of self-monitored blood pressure measurements during the follow-up is assessed by examining the memory of every single device at and,the written follow-up form filled up by each participant at 12 months. The target is considered adequate if it differs less than 5/3 mmHg from the national guide lines for treating hypertension (Office BP target <140/90 mmHg except diabetics <140/80 mmHg. Home BP target <135/85 mmHg except diabetics <135/75 mmHg) | baseline and 12 months from baseline |
