Impact of pharmacy care upon adherence to cardiovascular medicines: a feasibility pilot controlled trial

Pharmacist intervention to improve adherence to medication among heart failure patients at North East Ethiopia hospital

Heart failure (HF) is a major and growing medical problem and its management is still challenging due to the coexistence of complications, co-morbidity, and medication non-adherence. HF patients who are adherent to their medication have fewer HF exacerbations, improved survival, and lower healthcare expenditure. Adherence to HF medication plays a pivotal role in attaining maximal therapeutic outcomes. The aim was to assess the medication adherence of heart failure patients at Debre Berhan Comprehensive Specialized Hospital (DBCSH). A pre-post interventional study was undertaken from July 1, 2022, to December 31, 2022, at the medical referral clinic of DBCSH. The educational interventions were provided for 6 months. Medication adherence was determined using the Morisky Green Levin Medication Adherence Scale (MGLS). The data was entered into Epidata version 4.2.0 and analyzed using SPSS version 25.0 statistical software. Descriptive statistics and binary logistic regression analysis were performed. The strength of the association between predictor variables and outcome variables was determined using a 95% confidence interval and adjusted odd ratio. In the pre-intervention phase, 54.6% of patients had medium medication adherence, while in the post-intervention phase, 36.4% of patients had high medication adherence and 61.9% of patients had medium medication adherence. Following the intervention, medication cost (120, 50%), inadequate availability of drugs (75, 31%), and forgetfulness (30, 13%) were the main reasons for medication non-adherence. The presence of co-morbidity and the number of co-morbidity (p < .05) were significantly associated with the occurrence of decreased medication adherence in the pre-intervention phase. Interventions by pharmacists to educate HF patients about the nature of their disease and providing brochures to increase awareness of their medications have been shown to improve medication adherence.

The impact of pharmacy care and motivational interviewing on improving medication adherence in patients with cardiovascular diseases: A systematic review of randomised controlled trials

BACKGROUND

Cardiovascular disease (CVD) is prevalent worldwide, and for many patients, non-adherence to medication remains a problem. Motivational interviewing is a behavioural, communication strategy used as an intervention aimed to improve health outcomes.

AIMS

This systematic review sought to investigate the effect of motivational interviewing delivered as part of pharmacy care on medication adherence, and the effect this has on clinical outcomes. These included systolic and diastolic blood pressure, haemoglobin A1C, lipid profiles and cardiovascular risk scores.

METHOD

A systematic review was conducted in six databases: PubMed Central UK, Cochrane Library, CINAHL (EBSCO), PsycINFO, EMBASE and MEDLINE from the inception of motivational interviewing in 1983 to November 2020. Randomised controlled trials (RCTs) that assessed motivational interviewing as part of pharmacy care interventions were selected. The Cochrane risk of bias tool was used to assess the risk of bias for each included study. This review was registered with PROSPERO (registration number CRD42020222954).

RESULTS

A total of eight RCTs met the inclusion criteria. Five out of eight studies demonstrated medication adherence significantly improved following motivational interviewing interventions. One study showed a significant improvement for systolic blood pressure change by 7.2 mmHg (95% CI 1.6-12.8 mmHg); this reduction was observed in patients whose baseline blood pressure was above their target blood pressure. No statistically significant effect was seen across other clinical outcomes.

CONCLUSION

Motivational interviewing could be an effective behavioural strategy to enhance medication adherence in patients with CVD. Although the evidence is promising thus far, further research is required to explore the impact of motivational interviewing on clinical outcomes as well as the feasibility of implementing motivational interviewing interventions within existing pharmacy care services.

Pharmacist Intervention to Improve Medication Adherence in Patients with Acute Coronary Syndrome: The PRIMA-ACS Study

Background

Despite ample evidence of benefit, adherence to secondary prevention medication therapy after acute coronary syndrome (ACS) is often suboptimal. Hospital pharmacists are uniquely positioned to improve adherence by providing medication education at discharge.

Objective

To determine whether a standardized counselling intervention at hospital discharge significantly improved patients' adherence to cardiovascular medications following ACS.

Methods

This single-centre, prospective, nonrandomized comparative study enrolled patients with a primary diagnosis of ACS (January 2014 to July 2015). Patients who received standardized discharge counselling from a clinical pharmacist were compared with patients who did not receive counselling. At 30 days and 1 year after discharge, follow-up patient surveys were conducted and community pharmacy refill data were obtained. Adherence was assessed using pharmacy refill data and patient self-reporting for 5 targeted medications: acetylsalicylic acid, P2Y purinoceptor 12 (P2Y12) inhibitors, angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers, β-blockers, and statins. Thirty-day and 1-year medication utilization, cardiovascular readmission rates, and all-cause mortality were also assessed.

Results

Of the 259 patients enrolled, 88 (34.0%) received discharge counselling. Medication data were obtained for 253 patients (97.7%) at 30 days and 242 patients (93.4%) at 1 year. At 1 year after discharge, there were no statistically significant differences between patients who did and did not receive counselling in terms of rates of nonadherence (11.9% versus 18.4%, p = 0.19), cardiovascular readmission (17.6% versus 22.3%, p = 0.42), and all-cause mortality (3.4% versus 4.2%, p > 0.99). Overall medication nonadherence was 2.8% (7/253) at 30 days and 16.1% (39/242) at 1 year.

Conclusions

Discharge medication counselling provided by hospital pharmacists after ACS was not associated with significantly better medication adherence at 1 year. Higher-quality evidence is needed to determine the most effective and practical interventions to ensure that patients adhere to their medication regimens and achieve positive outcomes after ACS.

The NUDGE trial pragmatic trial to enhance cardiovascular medication adherence: study protocol for a randomized controlled trial

Background

Nearly half of patients do not take their cardiovascular medications as prescribed, resulting in increased morbidity, mortality, and healthcare costs. Mobile and digital technologies for health promotion and disease self-management offer an opportunity to adapt behavioral “nudges” using ubiquitous mobile phone technology to facilitate medication adherence. The Nudge pragmatic clinical trial uses population-level pharmacy data to deliver nudges via mobile phone text messaging and an artificial intelligent interactive chat bot with the goal of improving medication adherence and patient outcomes in three integrated healthcare delivery systems.

Methods

The Theory of mHealth, the Expanded RE-AIM/PRISM, and the PRECIS-2 frameworks were used for program planning, implementation, and evaluation, along with a focus on dissemination and cost considerations. During the planning phase, the Nudge study team developed and piloted a technology-based nudge message and chat bot of optimized interactive content libraries for a range of diverse patients. Inclusion criteria are very broad and include patients in one of three diverse health systems who take medications to treat hypertension, atrial fibrillation, coronary artery disease, diabetes, or hyperlipidemia. A target of approximately 10,000 participants will be randomized to one of 4 study arms: usual care (no intervention), generic nudge (text reminder), optimized nudge, and optimized nudge plus interactive AI chat bot. The PRECIS-2 tool indicated that the study protocol is very pragmatic, although there is variability across PRECIS-2 dimensions.

Discussion

The primary effectiveness outcome is medication adherence defined by the proportion of days covered (PDC) using pharmacy refill data. Implementation outcomes are assessed using the RE-AIM framework, with a particular focus on reach, consistency of implementation, adaptations, cost, and maintenance/sustainability. The project has limitations including limited power to detect some subgroup effects, medication complications (bleeding), and longer-term outcomes (myocardial infarction). Strengths of the study include the diverse healthcare systems, a feasible and generalizable intervention, transparent reporting using established pragmatic research and implementation science frameworks, strong stakeholder engagement, and planning for dissemination and sustainment.

Mobile Apps to Improve Medication Adherence in Cardiovascular Disease: Systematic Review and Meta-analysis

Background

Adherence rates of preventative medication for cardiovascular disease (CVD) have been reported as 57%, and approximately 9% of all CVD events in Europe are attributable to poor medication adherence. Mobile health technologies, particularly mobile apps, have the potential to improve medication adherence and clinical outcomes.

Objective

The objective of this study is to assess the effects of mobile health care apps on medication adherence and health-related outcomes in patients with CVD. This study also evaluates apps’ functionality and usability and the involvement of health care professionals in their use.

Methods

Electronic databases (MEDLINE [Ovid], PubMed Central, Cochrane Library, CINAHL Plus, PsycINFO [Ovid], Embase [Ovid], and Google Scholar) were searched for randomized controlled trials (RCTs) to investigate app-based interventions aimed at improving medication adherence in patients with CVD. RCTs published in English from inception to January 2020 were reviewed. The Cochrane risk of bias tool was used to assess the included studies. Meta-analysis was performed for clinical outcomes and medication adherence, with meta-regression analysis used to evaluate the impact of app intervention duration on medication adherence.

Results

This study included 16 RCTs published within the last 6 years. In total, 12 RCTs reported medication adherence as the primary outcome, which is the most commonly self-reported adherence. The duration of the interventions ranged from 1 to 12 months, and sample sizes ranged from 24 to 412. Medication adherence rates showed statistically significant improvements in 9 RCTs when compared with the control, and meta-analysis of the 6 RCTs reporting continuous data showed a significant overall effect in favor of the app intervention (mean difference 0.90, 95% CI 0.03-1.78) with a high statistical heterogeneity (I²=93.32%). Moreover, 9 RCTs assessed clinical outcomes and reported an improvement in systolic blood pressure, diastolic blood pressure, total cholesterol, and low-density lipoprotein cholesterol levels in the intervention arm. Meta-analysis of these clinical outcomes from 6 RCTs favored app interventions, but none were significant. In the 7 trials evaluating app usability, all were found to be acceptable. There was a great variation in the app characteristics. A total of 10 RCTs involved health care professionals, mainly physicians and nurses, in the app-based interventions. The apps had mixed functionality: 2 used education, 7 delivered reminders, and 7 provided reminders in combination with educational support.

Conclusions

Apps tended to increase medication adherence, but interventions varied widely in design, content, and delivery. Apps have an acceptable degree of usability; yet the app characteristics conferring usability and effectiveness are ill-defined. Future large-scale studies should focus on identifying the essential active components of successful apps.

Text Message Medication Adherence Reminders Automated and Delivered at Scale Across Two Institutions: Testing the Nudge System: Pilot Study

BACKGROUND

Medication refill behavior in patients with cardiovascular diseases is suboptimal. Brief behavioral interventions called Nudges may impact medication refill behavior and can be delivered at scale to patients using text messaging.

METHODS

Patients who were prescribed and filled at least one medication for hypertension, hyperlipidemia, diabetes, atrial fibrillation, and coronary artery disease were identified for the pilot study. Patients eligible for the pilot (N=400) were enrolled with an opportunity to opt out. In phase I of the pilot, we tested text message delivery to 60 patients. In phase II, we tested intervention feasibility by identifying those with refill gap of ≥7 days and randomized them to intervention or control arms. Patients were texted Nudges and assessed whether they refilled their medications.

RESULTS

Of 400 patients sent study invitations, 56 (14%) opted out. In phase I, we successfully delivered text messages to 58 of 60 patients and captured patient responses via text. In phase II, 207 of 286 (72.4%) patients had a medication gap ≥7 days for one or more cardiovascular medications and were randomized to intervention or control. Enrolled patients averaged 61.7 years old, were primarily male (69.1%) and White (72.5%) with hypertension being the most prevalent qualifying condition (78.7%). There was a trend towards intervention patients being more likely to refill at least 1 gapping medication (30.6% versus 18.0%; P=0.12) and all gapping medications (17.8% versus 10.0%; P=0.27).

CONCLUSIONS

It is possible to set up automated processes within health care delivery systems to identify patients with gaps in medication adherence and send Nudges to facilitate medication refills. Text message Nudges could potentially be a feasible and effective method to facilitate medication refills. A large multi-site randomized trial to determine the impact of text-based Nudges on overall CVD morbidity and mortality is now underway to explore this further.

Non-Adherence to Prescribed Antihypertensives in Primary, Secondary and Tertiary Healthcare Settings in Islamabad, Pakistan: A Cross-Sectional Study

OBJECTIVE

This study aimed to assess the prevalence and predictors of non-adherence to antihypertensive medication among patients with hypertension attending various healthcare settings in Islamabad, Pakistan.

METHODS

A questionnaire-based cross-sectional study was conducted in selected healthcare facilities between September 2017 and December 2018. The study was conducted in primary, secondary and tertiary healthcare settings in Islamabad, Pakistan. Medication adherence was assessed using the eight-item Morisky Medication Adherence Scale (MMAS-8). Sociodemographic and clinical data of recruited patients were collected through a structured questionnaire. Binary logistic regression analysis was performed to determine covariates significantly associated with medication adherence and blood pressure control.

RESULTS

A total of 776 hypertensive patients were invited and 741 (95%) completed the questionnaire. The mean ± SD age of participants was 53.6±12.6 years; 284 patients (38.3%) had high adherence, 178 (24%) had moderate adherence and 279 (37.7%) were non-adherent to the prescribed antihypertensive therapy. Binary regression analysis revealed that old age (OR 1.783 [95% CI: 1.172-2.712]; P=0.013), being educated (OR 2.018 [95% CI: 1.240-3.284]; P=0.036), entitlement to free medical care (OR 1.369 [95% CI: 1.009-1.859]; P=0.044), treatment duration (OR 2.868 [95% CI: 1.913-4.299]; P=0.001), number of medications (OR 1.973 [95% CI: 1.560-2.495]; P=0.001), presence of any comorbidity (OR 2.658 [95% CI: 1.836-3.848]; P=0.001) and blood pressure control (OR 3.103 [95% CI: 2.268-4.247]; P=0.001) were significantly associated with good adherence. Similarly, age (OR 1.998 [95% CI: 1.313-3.040]; P=0.004), entitlement to free medical care (OR 1.498 [95% CI: 1.116-2.010]; P=0.007), treatment duration (OR 1.886 [95% CI: 1.143-3.113]; P=0.013), presence of any comorbidity (OR 1.552 [95% CI: 1.123-2.147]; P=0.008) and adherence level (OR 3.103 [95% CI: 2.268-4.247]; P=0.001) had significant association with controlled blood pressure. The following were the main reasons for non-adherence to prescribed antihypertensive medication: "don't feel need for regular use" (24.7%), "Carelessness" (13.4%) and "adverse effects" (11.2%).

CONCLUSION

The prevalence of non-adherence to antihypertensive medications was high in the study population and poor medication adherence could potentially explain poor blood pressure control. Evidence-based targeted interventions on both medication adherence and blood pressure control should be introduced and implemented for better treatment outcomes.

Perceptions of UK Community Pharmacists on Current Consultation Skills and Motivational Interviewing as a Consultation Approach: A Qualitative Study

OBJECTIVES

Community pharmacists' roles in the UK are evolving; pharmacists currently deliver a wider range of clinical services with more patient-focused care. The objectives of this study were (i) to investigate UK community pharmacists' views on their current communication skills in pharmacist-patient facing consultations, and (ii) to explore the perceptions of UK community pharmacists towards the application of motivational interviewing (MI) in a pharmacy consultation. In-depth qualitative face-to-face, semi-structured interviews with ten practicing community pharmacists were carried out, ranging from 30-60 minutes in length. The interviews were audio recorded, transcribed verbatim and thematic analysis was employed. Four themes emerged from the data: (1) the fight for time; (2) wrestling with consultation styles; (3) a personal communication evolution; and (4) unfamiliar but engaging motivational interviewing. These themes demonstrated the juxtaposition between the desire for patient-centred care and the pressures of managing broader dispensing work. Participants were critical of academic and continuous professional learning (CPD) training in communication skills and there was a strong recognition of the potential role of MI in promoting patient autonomy and outcomes. Participants recognized a few elements of MI techniques in their current consultations, but welcomed further training on behavioral change for effective consultations, expressing a desire for practical MI-specific training. Face-to-face CPD of consultation skills is needed to avoid the feeling of isolation among UK practicing pharmacists and rigidity in consultation delivery. Support for community pharmacists from other pharmacy staff could relieve current pressures and allow pharmacists time to develop and acquire effective skills for patient facing roles. Behavioural change consultation skills training for pharmacists could be an effective strategy to address these current challenges.

Effect of pharmacist care on medication adherence and cardiovascular outcomes among patients post-acute coronary syndrome: A systematic review

BACKGROUND

The impact of collaborative and multidisciplinary health care on the outcomes of care in patients with acute coronary syndromes (ACS) is well-established in the literature. However, there is lack of high quality evidence on the role of pharmacist care in this setting.

OBJECTIVE

This systematic review aimed to evaluate the impact of pharmacist care on patient outcomes (readmission, mortality, emergency visits, and medication adherence) in patients with ACS at or post-discharge.

METHODS

The following electronic databases and search engines were searched from their inception to September 2016: PubMed, EMBASE, Cochrane Central Register of Controlled Trials, ISI Web of Science, Scopus, Campbell Library, Database of Abstracts of Reviews of Effects (DARE), Health System Evidence, Global Health Database, Joanna Briggs Institute Evidence-Based Practice Database, Academic Search Complete, ProQuest, PROSPERO, and Google Scholar. Studies were included if they evaluated the impact of pharmacist's care (compared with no pharmacist's care or usual care) on the outcomes of rehospitalization, mortality, and medication adherence in patients post-ACS discharge. Comparison of the outcomes with relevant statistics was summarized and reported.

RESULTS

A total of 17 studies [13 randomized controlled trials (RCTs) and four non-randomized clinical studies] involving 8391 patients were included in the review. The studies were of variable quality (poor to good quality) or risk of bias (moderate to critical risk). The nature and intensity of pharmacist interventions varied among the studies including medication reconciliation, medication therapy management, discharge medication counseling, motivational interviewing, and post-discharge face-to-face or telephone follow-up. Pharmacist-delivered interventions significantly improved medication adherence in four out of 12 studies. However, these did not translate to significant improvements in the rates of readmissions, hospitalizations, emergency visits, and mortality among ACS patients.

CONCLUSIONS

Pharmacist care of patients discharged after ACS admission was not associated with significant improvement in medication adherence or reductions in readmissions, emergency visits, and mortality. Future studies should use well-designed RCTs to assess the short- and long-terms effects of pharmacist interventions in ACS patients.
