Intervention / Treatment
Detailed Description
This is a prospective randomized two-group pharmacist-led interventional study that was conducted in two public nephrology clinics. The study involved the introduction of pharmaceutical care to improve blood pressure and adherence to the prescribed medications among patients with chronic kidney disease (CKD).
Recruited patients were randomly divided into two groups; the intervention group and the control group, with baseline evaluation of outcomes measured.
The Control group was provided with usual care. An intervention group was provided in addition to the usual care, face-to-face education on CKD, hypertension as a co-morbidity and its management, and antihypertensive medication adherence at baseline (group education), 6 months and 12 months (individualized according to each patient's needs), CKD patient educational infographic leaflet at baseline, a calibrated sphygmomanometer digital blood pressure monitor (Chidalex®) for home-based self-measured BP monitoring, a BP logbook at baseline for the recording of blood pressure values daily and hands-on training on BP self-measurement. Also, antihypertensive medication adherence and home-based self-measured BP monitoring, reminder cell phone text messages were sent biweekly throughout the trial period, while phone-in inquiries from the participants and phone-out reinforcement interventions were utilized throughout the trial period.
Both groups were followed for a period of 12 months.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
No Intervention: Usual Care
Participants in the UC arm received the usual/conventional care offered by the hospitals which included: hospital visits on appointment or a sick day, consultations with the physicians, prescription of drugs and routine laboratory tests, review of diagnosis and medications, refilling of prescriptions by patients and referral.

Experimental: Pharmacists' Intervention
Participants in the PI arm received routine usual care plus pharmacists' interventions for 12 months.
The PI arm received usual care plus face-to-face education on CKD, hypertension as a co-morbidity and its management, and antihypertensive medication adherence at baseline (group education), 6 months and 12 months (individualized according to each patient's needs), CKD patient educational infographic leaflet at baseline, a calibrated sphygmomanometer digital BP monitor (Chidalex®) for HSMBM, a BP logbook at baseline for the recording of BP values daily and hands-on training on BP self-measurement.
Also, antihypertensive medication adherence and HSMBM reminder cell phone text messages were sent biweekly throughout the trial period, while phone-in inquiries from the participants and phone-out reinforcement interventions were utilized throughout the trial period
|
Interventions were provided in groups of 4 - 10 participants after data collection at baseline while reinforcing individualized interventions were provided during subsequent visits to the research clinic for follow-up at 6 months and 12 months.
Medication reminder text messages were delivered to each participant biweekly.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Changes in mean blood pressure
Time Frame: 6 months and 12 months
|
Changes in both mean systolic and diastolic blood pressure.overtime
were determined
|
6 months and 12 months
|
Changes in blood pressure control
Time Frame: 6 months and 12 months
|
Changes in the proportion of participants with both controlled systolic and diastolic blood pressure less than 130/80 mmHg overtime were measured
|
6 months and 12 months
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Changes in mean antihypertensive medication adherence
Time Frame: 6 months and 12 months
|
Antihypertensive medication adherence was determined using the 4-item Morisky-Green-Levine (MGL) scale.
The response was scored as follows: a "yes" response was scored one point and zero to a "no" response.
The total score ranged from zero to four.
Adherence levels were then categorized into three based on the total score.
Zero, 1 - 2, and 3 - 4 were classified as high adherence, moderate adherence, and low adherence, respectively.
Lower scores mean a better outcome.
|
6 months and 12 months
|
Changes in mean serum creatinine levels
Time Frame: 6 months and 12 months
|
Participants' blood samples were analyzed for creatinine levels
|
6 months and 12 months
|
Participants' satisfaction with care received
Time Frame: 12 months
|
The Patient Satisfaction with Pharmacist Services Questionnaire (PSPSQ) 2.0 (Sakharkar et al., 2015) was used to assess patient satisfaction with care received.
The participants' responses to items 1-19 were scored 4 points, 3 points, 2 points, and 1 point, respectively for "strongly agreed", "agree", "disagree", and "strongly disagree".
However, item 20 was also scored 4 points, 3 points, 2 points, and 1 point, respectively for "exceeded your expectation", "met your expectation", "did not meet your expectation", and "I had no expectation".
For the quality of care domain, minimum value is 1 and maximum value is 40, For interpersonal relationship domain, minimum value is 1 and maximum value is 24.
For overall satisfaction domain, minimum value is 1 and maximum value is 16.Higher scores mean a better outcome.
