Relationship of treatment satisfaction to medication adherence: findings from a cross-sectional survey among hypertensive patients in Palestine

Abstract

BackgroundThe concepts of medication adherence and Treatment satisfactions are commonly used in clinical research for assessing pharmaceutical care and improving treatment outcomes. Generally, one would expect a positive relationship between the two concepts. The objectives of this study were to investigate the factors associated with adherence to antihypertensive therapy among hypertensive patients and to assess the relationship between antihypertensive medication adherence and treatment satisfaction.MethodsA cross-sectional study was conducted, adopting the Morisky eight-item Medication Adherence Scale (MMAS) for the assessment of medication adherence and using the Treatment Satisfaction Questionnaire for Medication (TSQM 1.4) for the assessment of treatment satisfaction. Descriptive and comparative statistics were used to describe socio-demographic and disease-related characteristics of the patients. All analyses were performed using SPSS v 15.0.ResultsFour hundred and ten hypertensive patients were enrolled in the study. The mean age of participants was 58.38 ± 10.65 years; 52% were female and 36.8% had low antihypertensive medication adherence. There was a significant difference in the mean scores in the Effectiveness (p < 0.001), Convenience (p < 0.001), and Global Satisfaction (p < 0.001) domains, but not in the Side Effects (p = 0.466) domain among patients with different levels of adherence. After adjustment for covariates using multiple linear regression, global treatment satisfaction was still statistically significantly (p = 0.001) associated with medication adherence.ConclusionsLow treatment satisfaction may be an important barrier for achieving high rates of adherence to treatment. These study findings could be helpful in clinical practice, mainly in the early treatment of hypertensive patients, at a point where improving treatment satisfaction is still possible.

Relationship Between Medication Adherence and Health Beliefs Among Patients with Hypertension in Oman: Pilot study

“…perceived self-efficacy, severity of the disease and the necessity of and concerns regarding the mediciation). 3,[7][8][9][10][11][12] For the MMAS, scores ranged from 0-8 with a cut-off value for adequate adherence set at ≥6 for the purposes of the current study. 7 Beliefs about medication necessity and concerns were measured using two subscales of a validated Arabic version of the Beliefs about Medicines Questionnaire (BMQ) obtained from the main developer of the original 11-item questionnaire, similarly scored on a fivepoint Likert scale.…”

“…8 For all questionnaires, higher scores reflect greater adherence, stronger beliefs and greater self-efficacy, respectively; in addition, previous research has confirmed the validity and reliability of these tools. [7][8][9][10][11] Permission to use these questionnaires was obtained from the relevant developers, including permission to use the Arabic versions of the tools. Only the BIPQ and MASES-R questionnaires were translated to Arabic by the researchers themselves; this was done using previously described translation methods.…”

“…The study instruments have been previously used by other studies [6][7][8][9][10][11][12][13][14][15][16].…”

“…The first seven items were yes/no questions while the eighth item was answered on a 5-point Likert scale. Scores can range from zero to eight, with one score given for each "No" answer except for item number five where one score was given for a "Yes" answer, and the eighth item with zero given for "all the time" and one score for "never/rarely" [6,7,12,13,26].…”

“…The other part covered patient clinical characteristics data including medical history, type II diabetes duration, body mass index, smoking status, and any medications. The medical history question was presented to the participant as a list of illnesses with a dichotomous (yes/no) response [6,7]. All participants were asked to state their current antidiabetic treatment to investigate the antidiabetic therapy type as well as insulin treatment during the past 1 year.…”
