Circ Cardiovasc Qual Outcomes 2024; 17:e010396. [PMID: 39027934 PMCID: PMC11338746 DOI: 10.1161/circoutcomes.123.010396] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Accepted: 03/29/2024] [Indexed: 07/20/2024]
Abstract
BACKGROUND Globally, only 13.8% of patients with hypertension have their blood pressure (BP) controlled. Trials testing interventions to overcome barriers to BP control have produced mixed results. Type of health care professional delivering the intervention may play an important role in intervention success. The goal of this meta-analysis is to determine which health care professionals are most effective at delivering BP reduction interventions. METHODS We searched Medline and Embase (until December 2023) for randomized controlled trials of interventions targeting barriers to hypertension control reporting who led intervention delivery. One hundred articles worldwide with 116 comparisons and 90 474 participants with hypertension were included. Trials were grouped by health care professional, and the effects of the intervention on systolic and diastolic BP were combined using random effects models and generalized estimating equations. RESULTS Pharmacist-led interventions , community health worker-led interventions, and health educator-led interventions resulted in the greatest systolic BP reductions of -7.3 (95% CI, -9.1 to -5.6), -7.1 (95% CI, -10.8 to -3.4), and -5.2 (95% CI, -7.8 to -2.6) mm Hg, respectively. Interventions led by multiple health care professionals, nurses, and physicians also resulted in significant systolic BP reductions of -4.2 (95% CI, -6.1 to -2.4), -3.0 (95% CI, -4.2 to -1.9), and -2.4 (95% CI, -3.4 to -1.5) mm Hg, respectively. Similarly, the greatest diastolic BP reductions were -3.9 (95% CI, -5.2 to -2.5) mm Hg for pharmacist-led and -3.7 (95% CI, -6.6 to -0.8) mm Hg for community health worker-led interventions. In pairwise comparisons, pharmacist were significantly more effective than multiple health care professionals, nurses, and physicians at delivering interventions. CONCLUSIONS Pharmacists and community health workers are most effective at leading BP intervention implementation and should be prioritized in future hypertension control efforts.

Abstract
BACKGROUND Adherence to antihypertensive drugs (AHDs) is crucial for controlling blood pressure (BP). We aimed to determine the effectiveness of measuring AHD concentrations using a dried blood spot (DBS) sampling method to identify nonadherence, combined with personalized feedback, in reducing resistant hypertension. METHODS We conducted a multicenter, randomized, controlled trial (RHYME-RCT, ICTRP NTR6914) in patients with established resistant hypertension. Patients were randomized to receive either an intervention with standard of care (SoC) or SoC alone. SoC consisted of BP measurement and DBS sampling at baseline, 3 months (t3), 6 months (t6), and 12 months (t12); AHD concentrations were measured but not reported in this arm. In the intervention arm, results on AHD concentrations were discussed during a personalized feedback conversation at baseline and t3. Study endpoints included the proportion of patients with RH and AHD adherence at t12. RESULTS Forty-nine patients were randomized to receive the intervention+SoC, and 51 were randomized to receive SoC alone. The proportion of adherent patients improved from 70.0 to 92.5% in the intervention+SoC arm ( P = 0.008, n = 40) and remained the same in the SoC arm (71.4%, n = 42). The difference in adherence between the arms was statistically significant ( P = 0.014). The prevalence of resistant hypertension decreased to 75.0% in the intervention+SoC arm ( P < 0.001, n = 40) and 59.5% in the SoC arm ( P < 0.001, n = 42) at t12; the difference between the arms was statistically nonsignificant ( P = 0.14). CONCLUSION Personalized feedback conversations based on DBS-derived AHD concentrations improved AHD adherence but did not reduce the prevalence of RH.

Abstract
BACKGROUND Clinical pharmacists have a pivotal role in the management of the patient's medication. However, it is necessary to know how pharmacist-mediated deprescribing could be implemented in a hospital setting according to hospital physicians. OBJECTIVE To explore physicians' views on the involvement of hospital pharmacists in the deprescribing process using the example of PPIs. METHODS A qualitative study using two focus groups with hospital physicians was conducted to determine their attitudes regarding deprescribing initiated by the hospital pharmacist. The interviews were recorded and transcribed using the NVivo analysis software. A thematic analysis led to a categorization of all the verbatims. RESULTS Hospital doctors are reluctant to deprescribe drugs initiated by a colleague and feel that it is the responsibility of the general practitioner (GP), who fails to do so due to lack of time. In this situation, the hospital pharmacist is in the best position to deprescribe because of his/her expertise in drug therapy. This should be a discussion between the hospital pharmacist, the hospital doctor, the GP and the patient. Deprescribing should always be adapted to the patient's context. CONCLUSION Hospital physicians are open to a pharmacist-mediated, patient-centred approach to deprescribing as long as the GP is involved.

Abstract
Background Digital health technology can be useful to improve the health of patients with diabetes and to support patient-centered care and self-management. In this cross-sectional study, we described the eHealth profile of patients with diabetes, based on their use of digital health technology, and its association with sociodemographic characteristics. Methods We used data from the "Qualité Diabète Valais" cohort study, conducted in one region of Switzerland (Canton Valais) since 2019. Participants with type 1 or type 2 diabetes completed questionnaires on sociodemographic characteristics and on the use of digital health technology. We defined eHealth profiles based on three features, i.e., ownership or use of (1) internet-connected devices (smartphone, tablet, or computer), (2) mHealth applications, and (3) connected health tools (activity sensor, smart weight scale, or connected blood glucose meter). We assessed the association between sociodemographic characteristics and participants' eHealth profiles using stratified analyses and logistic regression models. Results Some 398 participants (38% women) with a mean age of 65 years (min: 25, max: 92) were included. The vast majority (94%) were Swiss citizens or bi-national and 68% were economically inactive; 14% had a primary level education, 51% a secondary level, and 32% a tertiary level. Some 75% of participants had type 2 diabetes. Some 90% of the participants owned internet-connected devices, 43% used mHealth applications, and 44% owned a connected health tool. Older age and a lower educational level were associated with lower odds of all features of the eHealth profile. To a lesser extent, having type 2 diabetes or not being a Swiss citizen were also associated with a lower use of digital health technology. There was no association with sex. Conclusion While most participants owned internet-connected devices, only about half of them used mHealth applications or owned connected health tools. Older participants and those with a lower educational level were less likely to use digital health technology. eHealth implementation strategies need to consider these sociodemographic patterns among patients with diabetes.

Abstract
Objective: We evaluated the effect on long term blood pressure (BP) of an interprofessional team-based care (TBC) intervention, involving nurses, pharmacists, and physicians, compared to usual care. Methods: We conducted a pragmatic randomized controlled study in ambulatory clinics and community pharmacies in Switzerland (ClinicalTrials.gov: NCT02511093). Uncontrolled treated hypertensive patients were randomized to TBC or usual care (UC). In the TBC group, nurses and pharmacists met patients every 6 weeks to measure BP, assess lifestyle, support medication adherence, and provide health education for 6 months. After each visit, they wrote a report to the physician who could adjust antihypertensive therapy. The outcome was the intention-to-treat difference in mean daytime ambulatory blood pressure measurement (ABPM) and control (<135/85 mmHg) at 6 and 12 months. Results: Eighty-nine patients (60 men/29 women; mean (SD) age: 61(12) year) were randomized to TBC (n = 43) or UC (n = 46). At baseline, mean (SD) BP was 144(10)/90(8) mmHg and 147(12)/87(11) mmHg in the TBC and UC groups. At 6 months, the between-groups difference in daytime systolic ABPM was−3 mmHg [95% confidence interval (CI):−10 to +4; p = 0.45]; at 12 months, this difference was−7 mmHg [95% CI:−13 to−2; p = 0.01]. At 6 months, the between-groups difference in daytime diastolic ABPM was +2 mmHg [95% CI:−1 to +6; p = 0.20]; at 12 months, this difference was−2 mmHg [95% CI:−5 to +2; 0.42]. Upon adjustment for baseline covariates including baseline BP, the between-groups differences at 6 and 12 months were maintained. At 6 months, there was no difference in BP control. At 12 months, the TBC group tended to have a better control in systolic BP (p = 0.07) but not in diastolic BP (p = 0.33). Conclusion: While there was not significant effect on BP at 6 months of follow-up, the TBC intervention can help decrease long-term systolic BP among uncontrolled hypertensive patients.

Methodological quality and risk of bias of meta-analyses of pharmacy services: A systematic review. Res Social Adm Pharm 2020; 18:2403-2409. [PMID: 33358399 DOI: 10.1016/j.sapharm.2020.12.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2020] [Revised: 12/15/2020] [Accepted: 12/16/2020] [Indexed: 11/21/2022]
Abstract
BACKGROUND A suboptimal meta-analysis with misleading conclusions, frequently published in the healthcare journals, can compromise decision making in clinical practice. OBJECTIVE To evaluate the reporting quality, methodological quality, and risk of bias of meta-analyses of pharmacy services. METHODS Systematic searches to identify all the meta-analyses reporting the effect of pharmacy services were performed in PubMed, Scopus, and Web of Science. The reporting quality, the methodological quality, and the risk of bias of the included meta-analyses were evaluated using PRISMA checklist, R-AMSTAR, and ROBIS, respectively. RESULTS A total of 109 meta-analyses were eligible for the study. The heterogeneity, the quality of evidence, and the quality analyses were poorly reported on authors' conclusions (14.3%, 14.7%, and 17.4%, respectively). The median scores of PRISMA and R-AMSTAR tolls were 24 (IQR 21.75-25), and 30 (IQR 27-32.5), respectively. Additionally, most of the studies were considered as high risk of bias (n = 83, 76.1%). No association between the date of publication and guideline compliance exists. PRISMA score was higher in studies published in high impact factor journals (rho = 0.313; p = 0.002), in articles that reported the quality of evidence obtained (p = 0.018), and in those that stated the need for future studies in their conclusions (p = 0.011). R-AMSTAR score was higher in studies published in high impact factor journals (rho = 0.338; p = 0.001), in those which reported the quality of evidence (p = 0.002), and in articles that described the quality analyses in their conclusions (p = 0.046). An association between the risk of bias and the recognition of the need for further studies in their conclusions (p = 0.041) was also found. CONCLUSION The rapid increase of the meta-analyses of pharmacy services was not associated with higher quality. Mechanistic meta-analyses with poor conclusions are commonly published. Quality of the analyses, strength of evidence, heterogeneity, and absence of confrontation with current guidelines are rarely considered when synthetizing evidence and making recommendations.

Abstract
Background Electronic health (eHealth) refers to the use of information and communication technologies for health. It plays an increasingly important role in patients’ medication management. Objective To assess evidence on (1) whether eHealth for patients’ medication management can improve drug adherence and health outcomes in nonhospital settings and (2) which eHealth functions are commonly used and are effective in improving drug adherence. Methods We searched for randomized controlled trials (RCTs) on PubMed, MEDLINE, CINAHL, EMBASE, EmCare, ProQuest, Scopus, Web of Science, ScienceDirect, and IEEE Xplore, in addition to other published sources between 2000 and 2018. We evaluated the studies against the primary outcome measure of medication adherence and multiple secondary health care outcome measures relating to adverse events, quality of life, patient satisfaction, and health expenditure. The quality of the studies included was assessed using the Cochrane Collaboration’s Risk of Bias (RoB) tool. Results Our initial search yielded 9909 records, and 24 studies met the selection criteria. Of these, 13 indicated improvement in medication adherence at the significance level of P<.1 and 2 indicated an improved quality of life at the significance level of P<.01. The top 3 functions that were employed included mechanisms to communicate with caregivers, monitoring health features, and reminders and alerts. eHealth functions of providing information and education, and dispensing treatment and administration support tended to favor improved medication adherence outcomes (Fisher exact test, P=.02). There were differences in the characteristics of the study population, intervention design, functionality provided, reporting adherence, and outcome measures among the included studies. RoB assessment items, including blinding of outcome assessment and method for allocation concealment, were not explicitly reported in a large number of studies. Conclusions All the studies included were designed for patient home-based care application and provided a mechanism to communicate with caregivers. A targeted study population such as older patients should be considered to maximize the public health impact on the self-management of diseases.

Abstract
BACKGROUND Poor medication adherence contributes to inadequate control of hypertension. However, the value of adherence monitoring is unknown. OBJECTIVE To evaluate the impact of monitoring adherence with electronic pill bottles or bidirectional text messaging on improving hypertension control. DESIGN Three-arm pragmatic randomized controlled trial. PATIENTS One hundred forty-nine primary care patients aged 18-75 with hypertension and text messaging capabilities who were seen at least twice in the prior 12 months with at least two out-of-range blood pressure (BP) measurements, including the most recent visit. INTERVENTIONS Patients were randomized in a 1:2:2 ratio to receive (1) usual care, (2) electronic pill bottles for medication adherence monitoring (pill bottle), and (3) bidirectional text messaging for medication adherence monitoring (bidirectional text). MAIN MEASURES Change in systolic BP during the final 4-month visit compared with baseline. KEY RESULTS At the 4-month follow-up visit, mean (SD) change values in systolic blood pressure were - 4.7 (23.4) mmHg in usual care, - 4.3 (21.5) mmHg in the pill bottle arm, and - 4.6 (19.8) mmHg in the text arm. There was no significant change in systolic blood pressure between control and the pill bottle arm (p = 0.94) or the text messaging arm (p = 1.00), and the two intervention arms did not differ from each other (p = 0.93). CONCLUSIONS Despite good measured adherence, neither feedback with electronic pill bottles nor bidirectional text messaging about medication adherence improved blood pressure control. Adherence to prescribed medications was not improved enough to affect BP control or it was not the primary driver of poor control. TRIAL REGISTRATION clinicaltrials.gov (NCT02778542).

Abstract
PURPOSE Medication adherence (MA) is a key factor for hypertensive patients' blood pressure control and forgetfulness is one of the main reasons that cause medication non-adherence. If effective, low-cost reminder package (LCRP) has great potentials for large-scale promotion. Therefore, this study aims to evaluate the effectiveness of combining LCRP and health education to improve MA among hypertensive patients. PATIENTS AND METHODS A clustered randomized controlled trial was performed in Beijing. A total of 518 hypertensive patients recruited from 8 community health care centers were randomized to receive LCRP combined with case-based health education or usual care. Randomization was performed at community level. Multilevel modeling was used to evaluate the study effect. RESULTS MA scores did not differ significantly at baseline between the intervention group and the control group. The results of multilevel modeling indicated that MA scores increased more in the intervention group, and the intervention effect on MA was 0.287 (95% CI: [0.103, 0.471], P=0.002). Patients' systolic blood pressure (SBP) and diastolic blood pressure (DBP) were not improved (SBP: difference=0.536, 95% CI [-3.207, 4.278]; DBP: difference=-0.927, 95% CI [-3.283, 1.428]). CONCLUSION LCRP combined with case-based health education could significantly improve hypertensive patients' MA.

Abstract
BACKGROUND Poor medication adherence decreases treatment efficacy and worsens clinical outcomes, but average rates of adherence to long-term pharmacological treatments for chronic illnesses are only about 50%. Interventions for improving medication adherence largely focus on patients rather than on physicians; however, the strategies shown to be effective are complex and difficult to implement in clinical practice. There is a need for new care models addressing the problem of medication adherence, integrating this problem into the patient care process. Physicians tend to overestimate how well patients take their medication as prescribed. This can lead to missed opportunities to change medications, solve adverse effects, or propose the use of reminders in order to improve patients' adherence. Thus, providing physicians with feedback on medication adherence has the potential to prompt changes that improve their patients' adherence to prescribed medications. OBJECTIVES To assess the effects of providing physicians with feedback about their patients' medication adherence for improving adherence. We also assessed the effects of the intervention on patient outcomes, health resource use, and processes of care. SEARCH METHODS We conducted a systematic search of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and Embase, all from database inception to December 2016 and without any language restriction. We also searched ISI Web of Science, two trials registers, and grey literature. SELECTION CRITERIA We included randomised trials, controlled before-after studies, and interrupted time series studies that compared the effects of providing feedback to physicians about their patients' adherence to prescribed long-term medications for chronic diseases versus usual care. We included published or unpublished studies in any language. Participants included any physician and any patient prescribed with long-term medication for chronic disease. We included interventions providing the prescribing physician with information about patient adherence to medication. Only studies in which feedback to the physician was the sole intervention or the essential component of a multifaceted intervention were eligible. In the comparison groups, the physicians should not have had access to information about their patients' adherence to medication. We considered the following outcomes: medication adherence, patient outcomes, health resource use, processes of care, and adverse events. DATA COLLECTION AND ANALYSIS Two independent review authors extracted and analysed all data using standard methodological procedures expected by Cochrane and the Effective Practice and Organisation of Care group. Due to heterogeneity in study methodology, comparison groups, intervention settings, and measurements of outcomes, we did not carry out meta-analysis. We describe the impact of interventions on outcomes in tabular form and make a qualitative assessment of the effects of studies. MAIN RESULTS We included nine studies (23,255 patient participants): eight randomised trials and one interrupted time series analysis. The studies took place in primary care and other outpatient settings in the USA and Canada. Seven interventions involved the systematic provision of feedback to physicians concerning all their patients' adherence to medication, and two interventions involved issuing an alert for non-adherent patients only. Seven studies used pharmacy refill data to assess medication adherence, and two used an electronic device or self-reporting. The definition of adherence differed across studies, making comparisons difficult. Eight studies were at high risk of bias, and one study was at unclear risk of bias. The most frequent source of bias was lack of protection against contamination.Providing physicians with feedback may lead to little or no difference in medication adherence (seven studies, 22,924 patients), patient outcomes (two studies, 1292 patients), or health resource use (two studies, 4181 patients). Providing physicians with feedback on medication adherence may improve processes of care (e.g. more medication changes, dialogue with patient, management of uncontrolled hypertension) compared to usual care (four studies, 2780 patients). None of the studies reported an adverse event due to the intervention. The certainty of evidence was low for all outcomes, mainly due to high risk of bias, high heterogeneity across studies, and indirectness of evidence. AUTHORS' CONCLUSIONS Across nine studies, we observed little or no evidence that provision of feedback to physicians regarding their patients adherence to prescribed medication improved medication adherence, patient outcomes, or health resource use. Feedback about medication adherence may improve processes of care, but due to the small number of studies assessing this outcome and high risk of bias, we cannot draw firm conclusions on the effect of feedback on this outcome. Future research should use a clear, standardised definition of medication adherence and cluster-randomisation to avoid the risk of contamination.

Abstract
The COMmunity Pharamcists ASSist for Blood Pressure (COMPASS-BP) study aimed to assess the effectiveness of lifestyle support programs administered in community pharmacies on hypertension control. This open-label, two-armed parallel group, cluster-randomized controlled trial included 73 pharmacies (clusters) in Japan randomized to a control or intervention group. Eligible hypertensive patients (n = 125), aged 20-75 years, received the intervention (n = 64) or the control treatment (n = 61), as dictated by their pharmacy randomization. Patients in the intervention group received brochures and healthy lifestyle advice from pharmacists using motivational interviewing methods during pharmacy visits over a 12-week period, with their usual pharmacy care. Conversely, the control group just received usual care. The main outcome measure was a change in morning systolic blood pressure (SBP) from baseline to week 12. The intervention group exhibited a decrease in morning SBP that was 6.0 mmHg greater than that of the control group (95% confidence interval [CI]: -11.0 to -0.9, p = 0.021). In a mixed-effect model for repeated measures analysis, the intergroup difference in morning SBP decrease was -4.5 mmHg (95% CI: -8.5 to -0.6, p = 0.024). Our findings indicate that implementation of a lifestyle advice program in pharmacies is feasible and may lead to reduced blood pressure.

Abstract
OBJECTIVE This study aims to assess the efficacy of Electronic Monitoring Feedback (EMF) as an intervention to improve medication adherence (i.e. dose- or full adherence) and clinical outcomes in adult patients. METHODS A systematic search was performed in Medline, EMBASE, PsycINFO and Web of Science and reported according to the PRISMA guidelines. Randomised controlled trials (RCTs) comparing EMF with usual care were identified to systematically summarise the evidence for use of EMF in improving medication adherence and clinical outcomes. The GRADE approach was used to assess the quality of the body of evidence. RESULTS Of 9,993 initially-identified studies, ten studies (four of high-quality and six of low-quality) were included. The sample size of the studies included varied from 18 to 205 patients. Four of the six studies (66.7%) reported a significant positive effect of EMF on mean dose adherence levels, whereas a significant positive effect of EMF on mean full adherence levels was found in all of the included studies (100%, five out of five of the studies included). A significant positive effect of EMF on clinical outcomes was reported in one of the seven studies included. The overall effect of EMF on mean dose- and full adherence was positive and the overall effect of EMF on clinical outcomes was inconclusive. CONCLUSION Considering the positive effect of EMF on medication adherence, EMF might be a promising intervention to enhance medication adherence. However, the effect of EMF on clinical outcomes was inconclusive. Prior to implementing EMF in clinical practice, future research with high-quality studies (e.g. adequate sample sizes, follow-up periods and no interfering co-interventions) is required to examine the (long-term) efficacy of EMF.

Abstract
BACKGROUND A non-dispensing pharmacist conducts clinical pharmacy services aimed at optimizing patients individual pharmacotherapy. Embedding a non-dispensing pharmacist in primary care practice enables collaboration, probably enhancing patient care. The degree of integration of non-dispensing pharmacists into multidisciplinary health care teams varies strongly between settings. The degree of integration may be a determinant for its success. OBJECTIVES This study investigates how the degree of integration of a non-dispensing pharmacist impacts medication related health outcomes in primary care. METHODS In this literature review we searched two electronic databases and the reference list of published literature reviews for studies about clinical pharmacy services performed by non-dispensing pharmacists physically co-located in primary care practice. We assessed the degree of integration via key dimensions of integration based on the conceptual framework of Walshe and Smith. We included English language studies of any design that had a control group or baseline comparison published from 1966 to June 2016. Descriptive statistics were used to correlate the degree of integration to health outcomes. The analysis was stratified for disease-specific and patient-centered clinical pharmacy services. RESULTS Eighty-nine health outcomes in 60 comparative studies contributed to the analysis. The accumulated evidence from these studies shows no impact of the degree of integration of non-dispensing pharmacists on health outcomes. For disease specific clinical pharmacy services the percentage of improved health outcomes for none, partial and fully integrated NDPs is respectively 75%, 63% and 59%. For patient-centered clinical pharmacy services the percentage of improved health outcomes for none, partial and fully integrated NDPs is respectively 55%, 57% and 70%. CONCLUSIONS Full integration adds value to patient-centered clinical pharmacy services, but not to disease-specific clinical pharmacy services. To obtain maximum benefits of clinical pharmacy services for patients with multiple medications and comorbidities, full integration of non-dispensing pharmacists should be promoted.

Abstract
Background Blood pressure (BP) is poorly controlled among a large proportion of hypertensive outpatients. Innovative models of care are therefore needed to improve BP control. The Team-Based Care for improving Hypertension management (TBC-HTA) study aims to evaluate the effect of a team-based care (TBC) interprofessional intervention, involving nurses, community pharmacists and physicians, on BP control of hypertensive outpatients compared to usual care in routine clinical practice. Methods/design The TBC-HTA study is a pragmatic randomized controlled study with a 6-month follow-up which tests a TBC interprofessionnal intervention conducted among uncontrolled treated hypertensive outpatients in two ambulatory clinics and among seven nearby community pharmacies in Lausanne and Geneva, Switzerland. A total of 110 patients are being recruited and randomized to TBC (TBC: N = 55) or usual care group (UC: N = 55). Patients allocated to the TBC group receive the TBC intervention conducted by an interprofessional team, involving an ambulatory clinic nurse, a community pharmacist and a physician. A nurse and a community pharmacist meet patients every 6 weeks to measure BP, to assess lifestyle, to estimate medication adherence, and to provide education to the patient about disease, treatment and lifestyle. After each visit, the nurse and pharmacist write a summary report with recommendations related to medication adherence, lifestyle, and changes in therapy. The physician then adjusts antihypertensive therapy accordingly. Patients in the UC group receive usual routine care without sessions with a nurse and a pharmacist. The primary outcome is the difference in daytime ambulatory BP between TBC and UC patients at 6-month of follow-up. Secondary outcomes include patients’ and healthcare professionals’ satisfaction with the TBC intervention and BP control at 12 months (6 months after the end of the intervention). Discussion This ongoing study aims to evaluate the effect of a newly developed team-based care intervention engaging different healthcare professionals on BP control in a primary care setting in Switzerland. The results will inform policymakers on implementable strategies for routine clinical practice. Trial registration ClinicalTrials.gov registration: NCT02511093.

Immunosuppressive therapy after solid-organ transplantation: does the INTERMED identify patients at risk of poor adherence? Pharm Pract (Granada) 2016; 14:822. [PMID: 28042353 PMCID: PMC5184375 DOI: 10.18549/pharmpract.2016.04.822] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2016] [Accepted: 10/26/2016] [Indexed: 12/23/2022] Open
Abstract
Background: Lack of adherence to medication is a trigger of graft rejection in solid-organ transplant (SOT) recipients. Objective: This exploratory study aimed to assess whether a biopsychosocial evaluation using the INTERMED instrument before transplantation could identify SOT recipients at risk of suboptimal post-transplantation adherence to immunosuppressant drugs. We hypothesized that complex patients (INTERMED>20) might have lower medication adherence than noncomplex patients (INTERMED≤20). Methods: Each patient eligible for transplantation at the University Hospital of Lausanne, Switzerland, has to undergo a pre-transplantation psychiatric evaluation. In this context the patient was asked to participate in our study. The INTERMED was completed pre-transplantation, and adherence to immunosuppressive medication was monitored post-transplantation by electronic monitors for 12 months. The main outcome measure was the implementation and persistence to two calcineurin inhibitors, cyclosporine and tacrolimus, according to the dichotomized INTERMED score (>20 or ≤20). Results: Among the 50 SOT recipients who completed the INTERMED, 32 entered the study. The complex (N=11) and noncomplex patients (N=21) were similar in terms of age, sex and transplanted organ. Implementation was 94.2% in noncomplex patients versus 87.8% in complex patients (non-significant p-value). Five patients were lost to follow-up: one was non-persistent, and four refused electronic monitoring. Of the four patients who refused monitoring, two were complex and withdrew early, and two were noncomplex and withdrew later in the study. Conclusion: Patients identified as complex pre-transplant by the INTERMED tended to deviate from their immunosuppressant regimen, but the findings were not statistically significant. Larger studies are needed to evaluate this association further, as well as the appropriateness of using a nonspecific biopsychosocial instrument such as INTERMED in highly morbid patients who have complex social and psychological characteristics.

An Electronic Adherence Measurement Intervention to Reduce Clinical Inertia in the Treatment of Uncontrolled Hypertension: The MATCH Cluster Randomized Clinical Trial. J Gen Intern Med 2016; 31:1294-1300. [PMID: 27255750 PMCID: PMC5071278 DOI: 10.1007/s11606-016-3757-4] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2015] [Revised: 02/09/2016] [Accepted: 05/10/2016] [Indexed: 11/25/2022]
Abstract
BACKGROUND To appropriately manage uncontrolled hypertension, clinicians must decide whether blood pressure (BP) is above goal due to a need for additional medication or to medication nonadherence. Yet, clinicians are poor judges of adherence, and uncertainty about adherence may promote inertia with respect to medication modification. OBJECTIVE We aimed to determine the effect of sharing electronically-measured adherence data with clinicians on the management of uncontrolled hypertension. DESIGN This was a cluster randomized trial. PARTICIPANTS Twenty-four primary care providers (12 intervention, 12 usual care; cluster units) and 100 patients with uncontrolled hypertension (65 intervention, 35 usual care) were included in the study. INTERVENTIONS At one visit per patient, clinicians in the intervention group received a report summarizing electronically measured adherence to the BP regimen and recommended clinical actions. Clinicians in the control group did not receive a report. MAIN MEASURES The primary outcome was the proportion of visits with appropriate clinical management (i.e., treatment intensification among adherent patients and adherence counseling among nonadherent patients). Secondary outcomes included patient-rated quality of care and communication during the visit. KEY RESULTS The proportion of visits with appropriate clinical management was higher in the intervention group than the control group (45 out of 65; 69 %) versus (12 out of 35; 34 %; p = 0.001). A higher proportion of adherent patients in the intervention group had their regimen intensified (p = 0.01), and a higher proportion of nonadherent patients in the intervention group received adherence counseling (p = 0.005). Patients in the intervention group were more likely to give their clinician high ratings on quality of care (p = 0.05), and on measures of patient-centered (p = 0.001) and collaborative communication (p = 0.02). CONCLUSIONS Providing clinicians with electronically-measured antihypertensive adherence reports reduces inertia in the management of uncontrolled hypertension.

Toward appropriate criteria in medication adherence assessment in older persons: Position Paper. Aging Clin Exp Res 2016; 28:371-81. [PMID: 26630945 DOI: 10.1007/s40520-015-0435-z] [Citation(s) in RCA: 49] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2015] [Accepted: 07/30/2015] [Indexed: 10/23/2022]
Abstract
Nonadherence to medication regimens is a worldwide challenge; adherence rates range from 38 to 57 % in older populations with an average rate of less than 45 % and nonadherence contributes to adverse drug events, increased emergency visits and hospitalisations. Accurate measurement of medication adherence is important in terms of both research and clinical practice. However, the identification of an objective approach to measure nonadherence is still an ongoing challenge. The aim of this Position Paper is to describe the advantages and disadvantages of the known medication adherence tools (self-report, pill count, medication event monitoring system (MEMS) and electronic monitoring devices, therapeutic drug monitoring, pharmacy records based on pharmacy refill and pharmacy claims databases) to provide the appropriate criteria to assess medication adherence in older persons. To the best of our knowledge, no gold standard has been identified in adherence measurement and no single method is sufficiently reliable and accurate. A combination of methods appears to be the most suitable. Secondly, adherence assessment should always consider tools enabling polypharmacy adherence assessment. Moreover, it is increasingly evident that adherence, as a process, has to be assessed over time and not just at one evaluation time point (drug discontinuation). When cognitive deficits or functional impairments may impair reliability of adherence assessment, a comprehensive geriatric assessment should be performed and the caregiver involved. Finally, studies considering the possible implementation in clinical practice of adherence assessment tools validated in research are needed.

Abstract
This systematic review applied meta-analytic procedures to synthesize medication adherence interventions that focus on adults with hypertension. Comprehensive searching located trials with medication adherence behavior outcomes. Study sample, design, intervention characteristics, and outcomes were coded. Random-effects models were used in calculating standardized mean difference effect sizes. Moderator analyses were conducted using meta-analytic analogues of ANOVA and regression to explore associations between effect sizes and sample, design, and intervention characteristics. Effect sizes were calculated for 112 eligible treatment-vs.-control group outcome comparisons of 34,272 subjects. The overall standardized mean difference effect size between treatment and control subjects was 0.300. Exploratory moderator analyses revealed interventions were most effective among female, older, and moderate- or high-income participants. The most promising intervention components were those linking adherence behavior with habits, giving adherence feedback to patients, self-monitoring of blood pressure, using pill boxes and other special packaging, and motivational interviewing. The most effective interventions employed multiple components and were delivered over many days. Future research should strive for minimizing risks of bias common in this literature, especially avoiding self-report adherence measures.

Abstract
The lack of adherence to treatment in hypertension affects approximately 30 % of patients. The elderly, those with several co-morbidities, social isolation, low incomes or depressive symptoms are the most vulnerable to this problem. There is no ideal method to quantify the adherence to the treatment. Indirect methods are recommended in clinical practice. Any intervention strategy should not blame the patient and try a collaborative approach. It is recommended to involve the patient in decision-making. The clinical interview style must be patient-centered including motivational techniques. The improvement strategies that showed greater effectiveness in the compliance of hypertension treatment were: treatment simplification, appointment reminders systems, blood pressure self-monitoring, organizational improvements and nurse and pharmacists care. The combination of different interventions are recommended against isolated interventions.

Abstract
The relationship between adherence to antihypertension medications, treatment satisfaction and illness perception has not been studied so far. The primary objective of this study was to examine the association between adherence to medication, treatment satisfaction and illness perception in Lebanese hypertensive patients. The relation between medication adherence and blood pressure (BP) control was also assessed. In this cross-sectional study, patients were recruited from the physician's practice offices and community pharmacies in Beirut. Patients who had been treated for hypertension for at least 3 months were invited to participate in the study; they completed three questionnaires: the 8-item Morisky Medication Adherence Scale (MMAS-8), the Treatment Satisfaction Questionnaire for Medication (TSQM-4) and the Brief Illness Perception Questionnaire (BIPQ). BP was also measured and recorded. A total of 117 subjects were included, of whom 29.1% had poor adherence to their antihypertension treatment (MMAS-8 scores<6). The odds of having well-controlled hypertension was 3.5 times higher in patients with high adherence compared with patients with poor adherence (P=0.010). Treatment satisfaction was significantly greater in patients with good adherence (P<0.001). Neither socio-demographic, disease- nor drug-related characteristics of the participants were significantly associated with medication adherence. As for illness perception, even though the mean BIPQ score of adherent participants was lower than the mean score of non-adherent participants, this difference did not reach statistical significance. In conclusion, treatment satisfaction was found to be a predictor of adherence. Studies are needed to determine whether interventions to increase satisfaction can improve adherence and BP control.

Abstract
BACKGROUND People who are prescribed self administered medications typically take only about half their prescribed doses. Efforts to assist patients with adherence to medications might improve the benefits of prescribed medications. OBJECTIVES The primary objective of this review is to assess the effects of interventions intended to enhance patient adherence to prescribed medications for medical conditions, on both medication adherence and clinical outcomes. SEARCH METHODS We updated searches of The Cochrane Library, including CENTRAL (via http://onlinelibrary.wiley.com/cochranelibrary/search/), MEDLINE, EMBASE, PsycINFO (all via Ovid), CINAHL (via EBSCO), and Sociological Abstracts (via ProQuest) on 11 January 2013 with no language restriction. We also reviewed bibliographies in articles on patient adherence, and contacted authors of relevant original and review articles. SELECTION CRITERIA We included unconfounded RCTs of interventions to improve adherence with prescribed medications, measuring both medication adherence and clinical outcome, with at least 80% follow-up of each group studied and, for long-term treatments, at least six months follow-up for studies with positive findings at earlier time points. DATA COLLECTION AND ANALYSIS Two review authors independently extracted all data and a third author resolved disagreements. The studies differed widely according to medical condition, patient population, intervention, measures of adherence, and clinical outcomes. Pooling results according to one of these characteristics still leaves highly heterogeneous groups, and we could not justify meta-analysis. Instead, we conducted a qualitative analysis with a focus on the RCTs with the lowest risk of bias for study design and the primary clinical outcome. MAIN RESULTS The present update included 109 new RCTs published since the previous update in January 2007, bringing the total number of RCTs to 182; we found five RCTs from the previous update to be ineligible and excluded them. Studies were heterogeneous for patients, medical problems, treatment regimens, adherence interventions, and adherence and clinical outcome measurements, and most had high risk of bias. The main changes in comparison with the previous update include that we now: 1) report a lack of convincing evidence also specifically among the studies with the lowest risk of bias; 2) do not try to classify studies according to intervention type any more, due to the large heterogeneity; 3) make our database available for collaboration on sub-analyses, in acknowledgement of the need to make collective advancement in this difficult field of research. Of all 182 RCTs, 17 had the lowest risk of bias for study design features and their primary clinical outcome, 11 from the present update and six from the previous update. The RCTs at lowest risk of bias generally involved complex interventions with multiple components, trying to overcome barriers to adherence by means of tailored ongoing support from allied health professionals such as pharmacists, who often delivered intense education, counseling (including motivational interviewing or cognitive behavioral therapy by professionals) or daily treatment support (or both), and sometimes additional support from family or peers. Only five of these RCTs reported improvements in both adherence and clinical outcomes, and no common intervention characteristics were apparent. Even the most effective interventions did not lead to large improvements in adherence or clinical outcomes. AUTHORS' CONCLUSIONS Across the body of evidence, effects were inconsistent from study to study, and only a minority of lowest risk of bias RCTs improved both adherence and clinical outcomes. Current methods of improving medication adherence for chronic health problems are mostly complex and not very effective, so that the full benefits of treatment cannot be realized. The research in this field needs advances, including improved design of feasible long-term interventions, objective adherence measures, and sufficient study power to detect improvements in patient-important clinical outcomes. By making our comprehensive database available for sharing we hope to contribute to achieving these advances.

Abstract
This study is an in-depth-analysis to explain statistical heterogeneity in a systematic review of implementation strategies to improve guideline adherence of primary care physicians in the treatment of patients with cardiovascular diseases. The systematic review included randomized controlled trials from a systematic search in MEDLINE, EMBASE, CENTRAL, conference proceedings and registers of ongoing studies. Implementation strategies were shown to be effective with substantial heterogeneity of treatment effects across all investigated strategies. Primary aim of this study was to explain different effects of eligible trials and to identify methodological and clinical effect modifiers. Random effects meta-regression models were used to simultaneously assess the influence of multimodal implementation strategies and effect modifiers on physician adherence. Effect modifiers included the staff responsible for implementation, level of prevention and definition pf the primary outcome, unit of randomization, duration of follow-up and risk of bias. Six clinical and methodological factors were investigated as potential effect modifiers of the efficacy of different implementation strategies on guideline adherence in primary care practices on the basis of information from 75 eligible trials. Five effect modifiers were able to explain a substantial amount of statistical heterogeneity. Physician adherence was improved by 62% (95% confidence interval (95% CI) 29 to 104%) or 29% (95% CI 5 to 60%) in trials where other non-medical professionals or nurses were included in the implementation process. Improvement of physician adherence was more successful in primary and secondary prevention of cardiovascular diseases by around 30% (30%; 95% CI -2 to 71% and 31%; 95% CI 9 to 57%, respectively) compared to tertiary prevention. This study aimed to identify effect modifiers of implementation strategies on physician adherence. Especially the cooperation of different health professionals in primary care practices might increase efficacy and guideline implementation seems to be more difficult in tertiary prevention of cardiovascular diseases.

Abstract
BACKGROUND Guidelines should reduce inappropriate practice and improve the efficiency of treatment. Not only methodological quality but also acceptance and successful implementation in daily practice are crucial for the benefit on patients. Focusing on cardiovascular diseases (CVD), it is still unclear which implementation strategy can improve physician adherence to the recommendations of guidelines in primary care. METHODS We conducted a systematic review on randomized controlled trials about guideline implementation strategies on CVD. Medline, Embase, CENTRAL, conference proceedings and registers of ongoing studies were searched. RESULTS Eighty-four trials met our predefined inclusion criteria, of them 54 trials compared unimodal strategies and 30 multimodal strategies to usual care. Concerning unimodal strategies, 15 trials investigated provider reminder systems, 3 audit and feedback, 15 provider education, 4 patient education, 5 promotion of self-management and 14 organizational change. The strongest benefit of a unimodal implementation strategy was found due to organizational change (odds ratio 1.96; 95% CI 1.4 to 2.75), followed by patient education, provider education and provider reminder systems. Trials on the efficacy of audit and feedback and patient self-management showed differing results or small advantages in terms of physician adherence. Multimodal interventions showed almost similar effect measures and ranking of strategies. CONCLUSION The use of implementation strategies for the distribution of guidelines on CVD can be convincingly effective on physician adherence, regardless whether based on a unimodal or multimodal design. Three distinct strategies should be well considered in such an attempt: organizational changes in the primary care team, patient education and provider education.

Abstract
BACKGROUND Control of blood pressure (BP) remains a major challenge in primary care. Innovative interventions to improve BP control are therefore needed. By updating and combining data from 2 previous systematic reviews, we assess the effect of pharmacist interventions on BP and identify potential determinants of heterogeneity. METHODS AND RESULTS Randomized controlled trials (RCTs) assessing the effect of pharmacist interventions on BP among outpatients with or without diabetes were identified from MEDLINE, EMBASE, CINAHL, and CENTRAL databases. Weighted mean differences in BP were estimated using random effect models. Prediction intervals (PI) were computed to better express uncertainties in the effect estimates. Thirty-nine RCTs were included with 14 224 patients. Pharmacist interventions mainly included patient education, feedback to physician, and medication management. Compared with usual care, pharmacist interventions showed greater reduction in systolic BP (-7.6 mm Hg, 95% CI: -9.0 to -6.3; I(2)=67%) and diastolic BP (-3.9 mm Hg, 95% CI: -5.1 to -2.8; I(2)=83%). The 95% PI ranged from -13.9 to -1.4 mm Hg for systolic BP and from -9.9 to +2.0 mm Hg for diastolic BP. The effect tended to be larger if the intervention was led by the pharmacist and was done at least monthly. CONCLUSIONS Pharmacist interventions - alone or in collaboration with other healthcare professionals - improved BP management. Nevertheless, pharmacist interventions had differential effects on BP, from very large to modest or no effect; and determinants of heterogeneity could not be identified. Determining the most efficient, cost-effective, and least time-consuming intervention should be addressed with further research.

Abstract
OBJECTIVES Non-adherence to therapy is an important cause of suboptimal blood pressure control but few practical tools exist to accurately and routinely detect it. We used a simple urine-based assay to evaluate the prevalence of antihypertensive treatment non-adherence and its impact on blood pressure in a specialist hypertension centre. METHODS 208 hypertensive patients (125 new referrals, 66 follow-up patients with inadequate blood pressure control and 17 renal denervation referrals) underwent assessment of antihypertensive drug intake using high-performance liquid chromatography-tandem mass spectrometry (HP LC-MS/MS) urine analysis at the time of clinical appointment. A total of 40 most commonly prescribed antihypertensive medications (or their metabolites) were screened for in spot urine samples. RESULTS Overall, 25% of patients were totally or partially non-adherent to antihypertensive treatment (total non-adherence 10.1%, partial non-adherence 14.9%). The highest prevalence of partial and total non-adherence was among follow-up patients with inadequate blood pressure control (28.8%) and those referred for consideration of renal denervation (23.5%), respectively. There was a linear relationship between blood pressure and the numerical difference in detected/prescribed antihypertensive medications-every unit increase in this difference was associated with 3.0 (1.1) mm Hg, 3.1 (0.7) mm Hg and 1.9 (0.7) mm Hg increase in adjusted clinic systolic blood pressure, clinic diastolic blood pressure (DBP) and 24 h mean daytime DBP (p=0.0051, p=8.62 × 10(-6), p=0.0057), respectively. CONCLUSIONS Non-adherence to blood pressure lowering therapy is common, particularly in patients with suboptimal blood pressure control and those referred for renal denervation. HP LC-MS/MS urine analysis could be used to exclude non-adherence and better stratify further investigations and intervention.

Abstract
OBJECTIVES Adherence is critical for maximizing the effectiveness of pre-exposure prophylaxis (PrEP) in preventing HIV infection. Strategies for promoting adherence to HIV treatment, and their potential application to PrEP adherence, have received considerable attention. However, adherence promotion strategies for prevention medications have not been well characterized and may be more applicable to PrEP. We aimed to identify adherence support interventions that have been effective in other prevention fields and could be applied in the HIV prevention context to support pill taking among PrEP users. METHODS To identify adherence support interventions that could be evaluated and applied in the PrEP context, we conducted a systematic review across the following prevention fields: hypertension, latent tuberculosis infection, hyperlipidaemia, oral contraceptives, osteoporosis, malaria prophylaxis, and post-exposure prophylaxis for HIV infection. We included randomized controlled trials that evaluated the efficacy of interventions to improve adherence to daily oral medications prescribed for primary prevention in healthy individuals or for secondary prevention in asymptomatic individuals. RESULTS Our searches identified 585 studies, of which 48 studies met the eligibility criteria and were included in the review; nine evaluated multiple strategies, yielding 64 separately tested interventions. Interventions with the strongest evidence for improving adherence included complex, resource-intensive interventions, which combined multiple adherence support approaches, and low-cost, low-intensity interventions that provided education or telephone calls for adherence support. CONCLUSIONS Our review identified adherence interventions with strong evidence of efficacy across prevention fields and provides recommendations for evaluating these interventions in upcoming PrEP studies.

[PMID: 23947982 DOI: 10.1016/j.jval.2013.03.1631] [Citation(s) in RCA: 105] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/19/2011] [Revised: 03/09/2013] [Accepted: 03/16/2013] [Indexed: 06/02/2023]
Abstract
OBJECTIVES To systematically review the evidence on the impact of interventions to improve medication adherence in adults prescribed antihypertensive medications. METHODS An electronic search was undertaken of articles published between 1979 and 2009, without language restriction, that focused on interventions to improve antihypertensive medication adherence among patients (≥18 years) with essential hypertension. Studies must have measured adherence as an outcome of the intervention. We followed standard guidelines for the conduct and reporting of the review and conducted a narrative synthesis of reported data. RESULTS Ninety-seven articles were identified for inclusion; 35 (35 of 97, 36.1%) examined interventions to directly improve medication adherence, and the majority (58 of 97, 59.8%) were randomized controlled trials. Thirty-four (34 of 97, 35.1%) studies reported a statistically significant improvement in medication adherence. DISCUSSION/CONCLUSIONS Interventions aimed at improving patients' knowledge of medications possess the greatest potential clinical value in improving adherence with antihypertensive therapy. However, we identified several limitations of these studies, and advise future researchers to focus on using validated adherence measures, well-designed randomized controlled trials with relevant adherence and clinical outcomes, and guidelines on the appropriate design and analysis of adherence research.

Abstract
A systematic review was performed from published articles on compliance (PubMed), between 1975 and first of June 2011. Specifically those which measured medication adherence using indirect methods (RCS and/or MEMS-Medication Event Monitoring System) were searched. Descriptors used were: hypertension AND patient compliance AND medication adherence. The main objective is to update the topic of therapeutic compliance in arterial hypertension worldwide, with special attention to Spain, as well as a critical evaluation of the evolution of therapeutic compliance over the period 1975-2011. After analysing 37 research studies published worldwide, the results were: total number of 8623 hypertensive patients, of whom 25.62% were non-compliers (n=2209; 95% CI; 23.82-27.42), and 74.38% were compliers (n=6414; 95% CI; 73.32-75.44). The weighted average of non-compliance was 37.60%. We conclude that the default rate in the pharmacological treatment of hypertension worldwide is high.

Abstract
OBJECTIVE This systematic review and meta-analysis of randomized controlled trials (RCTs) assesses the effect of pharmacist care on cardiovascular disease (CVD) risk factors among outpatients with diabetes. RESEARCH DESIGN AND METHODS MEDLINE, EMBASE, CINAHL, and the Cochrane Central Register of Controlled Trials were searched. Pharmacist interventions were classified, and a meta-analysis of mean changes of blood pressure (BP), total cholesterol (TC), LDL cholesterol, HDL cholesterol, and BMI was performed using random-effects models. RESULTS The meta-analysis included 15 RCTs (9,111 outpatients) in which interventions were conducted exclusively by pharmacists in 8 studies and in collaboration with physicians, nurses, dietitians, or physical therapists in 7 studies. Pharmacist interventions included medication management, educational interventions, feedback to physicians, measurement of CVD risk factors, or patient-reminder systems. Compared with usual care, pharmacist care was associated with significant reductions for systolic BP (12 studies with 1,894 patients; -6.2 mmHg [95% CI -7.8 to -4.6]); diastolic BP (9 studies with 1,496 patients; -4.5 mmHg [-6.2 to -2.8]); TC (8 studies with 1,280 patients; -15.2 mg/dL [-24.7 to -5.7]); LDL cholesterol (9 studies with 8,084 patients; -11.7 mg/dL [-15.8 to -7.6]); and BMI (5 studies with 751 patients; -0.9 kg/m(2) [-1.7 to -0.1]). Pharmacist care was not associated with a significant change in HDL cholesterol (6 studies with 826 patients; 0.2 mg/dL [-1.9 to 2.4]). CONCLUSIONS This meta-analysis supports pharmacist interventions-alone or in collaboration with other health care professionals-to improve major CVD risk factors among outpatients with diabetes.

Abstract
STUDY DESIGN Randomized controlled trial. OBJECTIVE To assess whether monitoring increases brace-wearing compliance in patients with adolescent idiopathic scoliosis (AIS). SUMMARY OF BACKGROUND DATA Noncompliance is a barrier to brace treatment of AIS. Studies have demonstrated that monitoring improves medication compliance; however, this has not been investigated in spinal braces. METHODS Twenty-one patients (mean age = 12.4 ± 2.0 years) with AIS were prescribed treatment with a custom-made Thoraco-Lumbo-Sacral-Orthosis for 18 hours a day using a standardized script. Before beginning treatment, 10 patients were randomized to be informed that their compliance was monitored, whereas 11 patients were unaware. Compliance was measured via a temperature probe embedded within the Thoraco-Lumbo-Sacral-Orthosis hidden from view. RESULTS Patients who were notified that they had a monitor in their brace demonstrated significantly increased compliance during the first 14 weeks of treatment compared with those who were uninformed (85.7% vs. 56.5%, P = 0.029), corresponding to a mean difference of 5.24 hours of daily brace wear. CONCLUSION Electronic monitoring can improve compliance with orthoses in patients with spinal deformity during a short observation period.

Abstract
Blood pressure (BP) control remains sub-optimal all over the world. Medication adherence is an important determinant of BP control. None of the available methods for measuring medication adherence is currently regarded as a universal consensus gold standard. In this study, we evaluated the correlation between self-report (Morisky's Medication Adherence Self-assessment Scale) and electronic (eCap) methods of medication adherence assessment. The self-report measure was administered at study entry while electronic compliance data was collected prospectively. Almost all (97.4%) of enrolled patients completed the study. Medication adherence scores ranged from 0 to 100% (69.33, ± 27.57) and 6.6-100% (66.92 ± 22.59) for Morisky's scale and eCap, respectively (Wilcoxon rank sum test, p = 0.253). Modal class interval for adherence scores were 61-80% (n = 28, 37.3%) and 81-100% (n = 23, 30.7%) for the eCap and Morisky's scale respectively. Overall, a weak correlation was found between the two methods (r = 0.056). The weak correlation was also maintained in subgroup analysis defined by attainment of BP control (r = 0.109 vs 0.0009), age (range r = -0.53 to 0.067), sex (0.009 to 0.151), level of education (-0.217 to 0.276), and Mini Mental State Examination score (-0.107 to 0.258). Our findings suggest that these methods are not equivalent in the evaluation of medication adherence.

Abstract
BACKGROUND Poor adherence to medications is a significant health care issue, particularly among cardiovascular patients. A variety of interventions have been tested by researchers in an effort to identify the most effective approach to improving adherence. Interventions delivered by multiple health care professionals (HCPs) may have an impact on improving adherence to medications in patients with chronic conditions, although the evidence to support this is still limited. OBJECTIVE To investigate the impact of interventions delivered by HCPs within a multiprofessional team to improve patients' adherence to cardiovascular disease medications in community settings. SEARCH STRATEGY The search strategy involved the use of the following data bases: Google scholar, PubMed, Medline, Cinahl, Embase, IPA, and Cochrane Library, from 1994 to 2010. Search was restricted to articles published in English. SELECTION CRITERIA Cluster randomized trials, controlled randomized clinical trials, prospective randomized trials, and nonrandomized studies were included. We considered any intervention designed to enhance adherence to medication directed by more than 1 HCP. RESULTS We included 17 studies testing 3 different types of interventions directed by more than 1 HCP. The HCPs received a variety of training via educational lectures or interactive workshops. Informational, behavioral, and combined interventions were delivered to cardiovascular patients. The majority of studies using only informational interventions or a combination of behavioral and informational interventions showed improvements in clinical outcomes (ie, blood pressure and total cholesterol lowering). However, only 2 studies measured improvements in adherence but the results were not significant. In contrast, all interventions based on the behavior change strategies improved both clinical outcomes and adherence to medication. CONCLUSIONS Behavioral interventions delivered by a multiprofessional team appear to offer the best opportunity to improve clinical outcomes through improvements in adherence. However, whether interventions delivered by a multiprofessional team are more clinically effective than those delivered by a single HCP remain to be tested.

Abstract
BACKGROUND Although it is generally acknowledged that electronic monitoring of adherence to treatment improves blood pressure (BP) control by increasing patients' awareness to their treatment, little information is available on the long-term effect of this intervention. METHODS In this observational study among a total of 470 patients with mild-to-moderate hypertension, adherence was measured in 228 patients by means of both the Medication Event Monitoring System (MEMS) and pill count (intervention group), and in 242 patients by means of pill count alone (control group). During a follow-up period of 1 year consisting of seven visits to the physician's office, BP measurements were performed and medication adjusted based on the achieved BP. In addition, at each visit adherence to treatment was assessed. RESULTS On the basis of pill counts, median adherence to treatment did not differ between the intervention group and the control group (96.1% vs. 94.2%; P = 0.97). In both groups, systolic and diastolic BP decreased similarly: 23/13 vs. 22/12 mm Hg in the intervention and control group respectively. Drug changes and the number of drugs used were associated with BP at the start of study, but not with electronic monitoring. CONCLUSIONS In this study, electronic monitoring of adherence to treatment by means of MEMS did not lead to better long-term BP control nor did it result in less drug changes and drug use.

Abstract
Poor adherence to treatment is one of the major determinants of an uncontrolled blood pressure. Participation in a clinical trial may increase patient's adherence to treatment. This prompted us to investigate adherence and persistence profiles in patients with hypertension who had participated in a clinical trial, by collecting pharmacy refill data before, during, and after participation in the trial. Pharmacy refill data of 182 patients with hypertension who participated in the Home Versus Office Blood Pressure Measurements: Reduction of Unnecessary Treatment Study between 2001 and 2005 were obtained from 1999 until 2010. Refill adherence to treatment was compared for the periods before, during, and after this trial. Persistence to medication was investigated for the period after termination of the trial. Refill data were available for 22 600 prescriptions. Participation into the trial significantly increased refill adherence, from 90.6% to 95.6% (P<0.001). After the trial period, refill adherence decreased again to 91.8% (P<0.001), which did not differ from the adherence before the start of the trial (P=0.45). Except for adherence to trial medication, adherence to nontrial-related drugs also increased as a consequence of trial participation, from 77.6% to 89.6% (P<0.001). After termination of the trial, median persistence was 1424 days. Participants classified as adherent (adherence: >90%) were less likely to discontinue treatment compared with nonadherent participants (odds ratio: 0.66 [95% CI: 0.45 to 0.98]). Participation in a clinical trial significantly increases adherence to both trial-related and nontrial-related treatment, suggesting that participants in a trial are more involved with their conditions and treatments.

Abstract
PURPOSE Pharmacist interventions to enhance blood pressure (BP) control and adherence to antihypertensive therapy in adults with essential hypertension were reviewed. METHODS A literature search was conducted to identify relevant articles describing pharmacist interventions intended to improve adherence to antihypertensive medications. Studies were included if they described a pharmacist intervention to improve medication adherence and analyzed adherence to therapy and BP control as outcomes. A fixed-effects model was used to combine data from randomized controlled trials. RESULTS A total of 15 studies were identified, testing 16 different interventions and containing data on 3280 enrolled patients. Although 87.5% of the interventions resulted in significant improvements in treatment outcomes, only 43.8% of the interventions were associated with significant increases in medication adherence. All interventions that increased antihypertensive medication adherence also significantly reduced BP. Almost all the interventions that were effective in increasing adherence to medication were complex, including combinations of different strategies. Meta-analysis of 2619 patients in 8 studies found that pharmacist interventions significantly reduced systolic blood pressure (SBP) (p < 0.001) and diastolic blood pressure (DBP) (p = 0.002) and that the meta-analytic differences in SBP and DBP changes from baseline to endpoint in intervention and control groups were -4.9 ± 0.9 mm Hg (p < 0.001) and -2.6 ± 0.9 mm Hg (p < 0.001), respectively. CONCLUSION A literature review and meta-analysis showed that pharmacist interventions can significantly improve medication adherence, SBP, DBP, and BP control in patients with essential hypertension. Interventions were complex and multifaceted and included medication management in all analyzed studies.

Abstract
BACKGROUND Uncontrolled hypertension despite treatment is highly prevalent among hypertension patients. Electronic monitoring of medication adherence has been proven to be effective in improving blood pressure. The aim of the study was to compare the effectiveness of intensive support for implementation of this tool in community pharmacies with minimal implementation support. METHODS In a cluster randomized trial, 25 control pharmacies received a manual and 32 experimental pharmacies received intensive support to enhance implementation of electronic monitoring. PRIMARY OUTCOME the number of patients included for electronic monitoring. Secondary outcomes included mean change in systolic blood pressure (SBP) and percentage of patients with adequate SBP control. RESULTS The experimental group yielded consistently higher scores on all the steps of the implementation process than the control group, but none of these differences were significant. The mean number of patients per pharmacy included for electronic monitoring in a 3-9-months period was 1.6 in the experimental group vs. 1.0 in the control group (difference = 0.7, 95% confidence interval = -0.4; 1.7). The following patient outcomes were pooled because there were no differences between the experimental and the control group. Mean change of SBP/diastolic blood pressure (DBP) was -12 and -6 mm Hg, respectively, SBP dropped <140 mm Hg in 20.9% of all patients. In 13.6% of all patients control of SBP was achieved without treatment intensification. CONCLUSION The intensive implementation program enhanced pharmacist performance, but appeared insufficient to overcome all problems with the implementation of electronic monitoring. The major restrictive factors concerned general practitioner (GP) involvement and the identification of eligible patients.

Abstract
BACKGROUND Uncontrolled hypertension is a major primary healthcare problem. AIM To investigate whether blood pressure (BP) control in primary care could be improved by nurses taking responsibility for managing hypertensive patients. METHODS Randomized trial with two groups: usual or intensive care. Patients diagnosed previously as hypertensive and with a systolic office BP greater than 140mmHg were randomized to an intensive care programme managed by trained nurses or to usual care. The intensive care programme included a visit every 6 weeks to the general practitioner's office, with standardized BP measurement, self-measurement training, risk factor checks and advice on BP reduction. The intervention lasted for 1 year. The primary endpoints were systolic BP obtained by 24-hour ambulatory BP monitoring after 1 year and the change compared with baseline. RESULTS Two hundred patients from 19 physicians were enrolled (102 in the intensive care group). Data on ambulatory BP were available from 140 patients. Systolic BP declined from 134.4+/-14.0 to 126.3+/-10.4mmHg in the intensive care group and from 132.4+/-13.5 to 128.2+/-13.0mmHg in the usual care group. There was no statistically significant difference in values after 1 year (p=0.332). The reduction in systolic BP was significantly greater in the intensive care group (7.6 vs 3.3mmHg in the usual care group; p=0.036). Similar results were observed for diastolic BP and day- and night-time measurements. CONCLUSIONS An intensive medical care programme in the office setting managed by trained nurses can improve BP control effectively. Nurses could take more responsibility for managing hypertensive patients.

Abstract
Hypertension affects nearly one third of the US population overall, and the prevalence rises sharply with age. In spite of public educational campaigns and professional education programs to encourage blood pressure measurement and control of both systolic and diastolic control to <140/90 mm Hg (or 130/80 mm Hg if diabetic), 43% of treated hypertensives do not achieve the recommended Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure target. Among blacks, 48% are uncontrolled on treatment. The majority of persons classified as poorly controlled hypertensives have mild systolic blood pressure elevation (in the range of 140 to 160 mm Hg). We hypothesized that physician uncertainty regarding the patient's usual blood pressure, as well as uncertainty regarding the extent of medication nonadherence, represent an important barrier to further reductions in the proportion of uncontrolled hypertensives in the United States. Using cluster randomization, 10 primary care clinics (6 from a public health care system and 4 from a private clinic system) were randomized to either the uncertainty reduction intervention condition or to usual care. An average of 68 patients per clinic were recruited to serve as units of observation. Physicians in the 5 intervention clinics were provided with a specially designed study form that included a graph of recent blood pressure measurements in their study patients, a check box to indicate their assessment of the adequacy of the patient's blood pressure control, and a menu of services they could order to aid in patient management. These menu options included 24-hour ambulatory blood pressure monitoring; electronic bottle cap assessment of medication adherence, followed by medication adherence counseling in patients found to be nonadherent; and lifestyle assessment and counseling followed by 24-hour ambulatory blood pressure monitoring. Physicians in the 5 usual practice clinics did not have access to these services but were informed of which patients had been enrolled in the study. Substudies carried out to further characterize the study population and interpret intervention results included ambulatory blood pressure monitoring and electronic bottle cap monitoring in a random subsample of patients at baseline, and audio recording of patient-physician encounters after intervention implementation. The primary study end point was defined as the proportion of patients with controlled blood pressure (<140/90 mm Hg or <130/80 mm Hg if diabetic). Secondary end points include actual measured clinic systolic and diastolic blood pressure, patient physician communication patterns, physician prescribing patient self-reported lifestyle and medication adherence, physician knowledge, attitude and beliefs regarding the utility of intervention tools to achieve blood pressure control, and the cost-effectiveness of the intervention. Six-hundred eighty patients have been randomized, and 675 remain in active follow-up after 1.5 years. Patient closeout will be complete in March 2009. Analyses of the baseline data are in progress. Office-based blood pressure measurement error and bias, as well as physician and patient beliefs about the need for treatment intensification, may be important factors that limit further progress in blood pressure control. This trial will provide data on the extent to which available technologies not widely used in primary care will change physician prescribing behavior and patient adherence to prescribed treatment.

Abstract
BACKGROUND Six pioneer physicians-pharmacists quality circles (PPQCs) located in the Swiss canton of Fribourg (administratively corresponding to a state in the US) were under the responsibility of 6 trained community pharmacists moderating the prescribing process of 24 general practitioners (GPs). PPQCs are based on a multifaceted collaborative process mediated by community pharmacists for improving compliance with clinical guidelines within GPs' prescribing practices. OBJECTIVE To assess, over a 9-year period (1999-2007), the cost-containment impact of the PPQCs. METHODS The key elements of PPQCs are a structured continuous quality improvement and education process; local networking; feedback of comparative and detailed data regarding costs, drug choice, and frequency of prescribed drugs; and structured independent literature review for interdisciplinary continuing education. The data are issued from the community pharmacy invoices to the health insurance companies. The study analyzed the cost-containment impact of the PPQCs in comparison with GPs working in similar conditions of care without particular collaboration with pharmacists, the percentage of generic prescriptions for specific cardiovascular drug classes, and the percentage of drug costs or units prescribed for specific cardiovascular drugs. RESULTS For the 9-year period, there was a 42% decrease in the drug costs in the PPQC group as compared to the control group, representing a $225,000 (USD) savings per GP only in 2007. These results are explained by better compliance with clinical and pharmacovigilance guidelines, larger distribution of generic drugs, a more balanced attitude toward marketing strategies, and interdisciplinary continuing education on the rational use of drugs. CONCLUSIONS The PPQC work process has yielded sustainable results, such as significant cost savings, higher penetration of generics and reflection on patient safety, and the place of "new" drugs in therapy. The PPQCs may also constitute a solid basis for implementing more comprehensive collaborative programs, such as medication reviews, adherence-enhancing interventions, or disease management approaches.

Abstract
BACKGROUND Poor adherence to antihypertensive medication is one of the major problems in the treatment of hypertension. Electronic monitoring is currently considered to be the gold standard for assessing adherence, but it may trigger patients to open the pill bottle without taking medication or to take out more than prescribed. In adjunct to electronic monitoring, pill count could be a valuable tool for exploring adherence patterns, and their effects on blood pressure reduction. METHODS Among a total of 228 patients with mild-to-moderate hypertension, adherence to treatment was measured by means of both the Medication Event Monitoring System (MEMS) and pill count. Patients were followed-up for seven visits over a period of 1 year. At each visit to the physician's office, patient's adherence was assessed by both methods. RESULTS Adherence is defined as the percentage of days with correct dosing; median adherence according to MEMS was lower than median adherence according to pill count (91.6 vs. 96.1; P < 0.001). Both methods agreed in defining patients as adherent in 107 (47%) and nonadherent in 33 (14%) patients. Thirty-one (14%) patients were adherent only by MEMS and 59 (25%) patients only by pill count. At the end of the study, patients in the four categories reached comparable blood pressure values and reductions. CONCLUSIONS Pill count could be a useful adjunct to electronic monitoring in assessing adherence patterns. Although deviant intake behavior occurred frequently, the effect on achieved blood pressure and blood pressure reduction was not remarkable.

Abstract
Nonadherence to medication treatment regimens is a major preventable risk behavior in both acute and chronic diseases. Community pharmacists are facilitators in community care for promoting medication adherence and they should implement interdisciplinary medication adherence programs. To do so, pharmacists should be educated in medication adherence, and new pharmaceutical care policies should be implemented. The healthcare system should evolve to better meet the specific needs of patients. AIMS this article describes what has been undertaken in the last decade in medication adherence in terms of education, research, practice and policy in Switzerland. METHODS Medline was searched, with the search limited to Switzerland. The three Swiss pharmacy schools were also contacted to collect information about the medication adherence content of both their courses and research programs. National policies related to medication adherence were also reviewed for relevant content. RESULTS EDUCATION two pharmacy schools offer courses devoted specifically to medication adherence. The number of hours dedicated to the topic varies between 4 to13. RESEARCH a total of 16 studies met the inclusion criteria. Chronic patients were the focus of 9 studies. Medication adherence was the primary outcome of all studies; 10 studies also measured clinical outcomes. Nine studies evaluated the prevalence of medication nonadherence; three studies evaluated the feasibility of new technologies for monitoring adherence; three studies evaluated medication adherence enhancing programs. Policies: three cognitive pharmaceutical services are reimbursed by healthcare insurers, which are directly related to medication adherence. CONCLUSIONS Pharmacists in Switzerland have been actively involved in medication adherence research since the mid '90s. Specific medication adherence courses have entered the curriculum of pharmacy schools, and policies in Switzerland are slowly beginning to meet needs of chronic patients by the introduction of pharmaceutical cognitive services and reimbursement fees.
