Project description:The Southeastern United States has the highest prevalence of hypertension and African Americans have disproportionately worse blood pressure control. The authors sought to evaluate the effect of a multicomponent practice-based quality improvement intervention on lowering mean systolic blood pressure (SBP) at 12 and 24 months compared with baseline among 525 patients, and to assess for a differential effect of the intervention by race (African Americans vs white). At 12 months, both African Americans (-5.0 mm Hg) and whites (-7.8 mm Hg) had a significant decrease in mean SBP compared with baseline, with no significant between-group difference. Similarly, at 24 months, mean SBP decreased in both African Americans (-6.0 mm Hg) and whites (-7.2 mm Hg), with no significant difference between groups. Notably, no significant racial disparity in mean SBP at baseline was shown. The intervention was effective in lowering mean SBP in both African Americans and whites but there was no differential effect of the intervention by race.

Project description:The objective of this study was to describe medication adherence and medication intensification in a physician-pharmacist collaborative management (PPCM) model compared with usual care. This study was a prospective, cluster, randomized study in 32 primary care offices from 15 states. The primary outcomes were medication adherence and anti-hypertensive medication changes during the first 9 months of the intervention. The 9-month visit was completed by 539 patients, 345 of which received the intervention. There was no significant difference between intervention and usual care patients in regards to medication adherence at 9 months. Intervention patients received significantly more medication changes (4.9 vs.1.1; P = .0003) and had significantly increased use of diuretics and aldosterone antagonists when compared with usual care (P = .01).The PPCM model increased medication intensification; however, no significant change in medication adherence was detected. PPCM models will need to develop non-adherence identification and intervention methods to further improve the potency of the care team.

Project description:BACKGROUND:Poor adherence to immunosuppressive medications is a major cause of premature graft loss among children and young adults. Multicomponent interventions have shown promise but have not been fully evaluated. STUDY DESIGN:Unblinded parallel-arm randomized trial to assess the efficacy of a clinic-based adherence-promoting intervention. SETTING & PARTICIPANTS:Prevalent kidney transplant recipients 11 to 24 years of age and 3 or more months posttransplantation at 8 kidney transplantation centers in Canada and the United States (February 2012 to May 2016) were included. INTERVENTION:Adherence was electronically monitored in all participants during a 3-month run-in, followed by a 12-month intervention. Participants assigned to the TAKE-IT intervention could choose to receive text message, e-mail, and/or visual cue dose reminders and met with a coach at 3-month intervals when adherence data from the prior 3 months were reviewed with the participant. "Action-Focused Problem Solving" was used to address adherence barriers selected as important by the participant. Participants assigned to the control group met with coaches at 3-month intervals but received no feedback about adherence data. OUTCOMES:The primary outcomes were electronically measured "taking" adherence (the proportion of prescribed doses of immunosuppressive medications taken) and "timing" adherence (the proportion of doses of immunosuppressive medications taken between 1 hour before and 2 hours after the prescribed time of administration) on each day of observation. Secondary outcomes included the standard deviation of tacrolimus trough concentrations, self-reported adherence, acute rejection, and graft failure. RESULTS:81 patients were assigned to intervention (median age, 15.5 years; 57% male) and 88 to the control group (median age, 15.8 years; 61% male). Electronic adherence data were available for 64 intervention and 74 control participants. Participants in the intervention group had significantly greater odds of taking prescribed medications (OR, 1.66; 95% CI, 1.15-2.39) and taking medications at or near the prescribed time (OR, 1.74; 95% CI, 1.21-2.50) than controls. LIMITATIONS:Lack of electronic adherence data for some participants may have introduced bias. There was low statistical power for clinical outcomes. CONCLUSIONS:The multicomponent TAKE-IT intervention resulted in significantly better medication adherence than the control condition. Better medication adherence may result in improved graft outcomes, but this will need to be demonstrated in larger studies.

Project description:BackgroundInadequate treatment of hypertension is a widespread problem, especially in South Asian countries where cardiovascular disease mortality rates are high. We aimed to explore the effect of a multicomponent intervention (MCI) on antihypertensive medication intensification among rural South Asians with hypertension.MethodsA post hoc analysis of a 2-year cluster-randomized controlled trial including 2,645 hypertensives aged ≥40 years from 30 rural communities, 10 each, in Bangladesh, Pakistan, and Sri Lanka. Independent assessors collected information on participants' self-reports and physical inspection of medications. The main outcomes were the changes from baseline to 24 months in the following: (i) the therapeutic intensity score (TIS) for all (and class-specific) antihypertensive medications; (ii) the number of antihypertensive medications in all trial participants.ResultsAt 24 months, the mean increase in the TIS score of all antihypertensive medications was 0.11 in the MCI group and 0.03 in the control group, with a between-group difference in the increase of 0.08 (95% confidence interval (CI, 0.03, 0.12); P = 0.002). In MCI compared with controls, a greater increase in the TIS of renin-angiotensin-aldosterone system blockers (0.05; 95% CI (0.02, 0.07); P < 0.001) and calcium channel blockers (0.03; 95% CI (0.00, 0.05); P = 0.031), and in the number of antihypertensive medications (0.11, 95% CI (0.02, 0.19); P = 0.016) was observed.ConclusionsIn rural communities in Bangladesh, Pakistan, and Sri Lanka, MCI led to a greater increase in antihypertensive medication intensification compared with the usual care among adults with hypertension.Clinical trials registrationTrial Number NCT02657746.

Project description:Background: Medication adherence can prevent health risks, but many patients do not adhere to their prescribed treatment. Our recent trial found that a digital intervention was effective at improving medication adherence in non-adherent patients with Hypertension or Type 2 Diabetes; but we do not know how it brought about behavioural changes. This research is a post-trial process evaluation of the mechanism by which the intervention achieved its intended effects. Methods: A mixed methods design with quantitative and qualitative evidence synthesis was employed. Data was generated by two studies. Study 1 used questionnaires to measure the underlying mechanisms of and the medication adherence behaviour, and digital logfiles to objectively capture intervention effects on the process of behaviour change. Multilevel regression analysis on 57 complete intervention group cases tested the effects of the intervention at modifying the mechanism of behaviour change and in turn at improving medication adherence. Study 2 used in depth interviews with a subsample of 20 intervention patients, and eight practise nurses. Thematic analysis provided evidence about the overarching intervention functions and recommendations to improve intervention reach and impact in primary care. Results: Study 1 found that intervention effectiveness was significantly associated with positive changes in the underlying mechanisms of behaviour change (R 2 = 0.26, SE = 0.98, P = 0.00); and this effect was heightened twofold when the tailored intervention content and reporting on medication taking (R 2 = 0.59, SE = 0.74, P = 0.00) was interested into the regression model. Study 2 suggested that the intervention supported motivation and ability to adherence, although clinically meaningful effects would require very brief medication adherence risk appraisal and signposting to ongoing digitally delivered behavioural support during clinical consultations. Conclusion: This post trial process evaluation used objective methods to capture the intervention effect on the mechanisms of behaviour change to explain intervention effectiveness, and subjective accounts to explore the circumstances under which these effects were achieved. The results of this process evaluation will inform a large scale randomised controlled trial in primary care.

Project description:PurposeTo assess the efficacy of the Support, Educate, Empower (SEE) glaucoma coaching program on medication adherence among glaucoma patients with low adherence.DesignUncontrolled intervention study with a pre-post design.ParticipantsGlaucoma patients ≥ age 40, taking ≥1 medication, who self-reported poor adherence were recruited from the University of Michigan Kellogg Eye Center. Adherence was monitored electronically for a 3-month baseline period; participants with median adherence of ≤80% were enrolled in the SEE program.MethodsParticipants' adherence was monitored electronically (AdhereTech, New York, NY) during the 7-month program. Adherence was calculated as the percentage of doses taken on time of those prescribed. The SEE program included (1) automated medication reminders, (2) 3 in-person counseling sessions with a glaucoma coach who had training in motivational interviewing (MI), and (3) 5 phone calls with the same coach for between-session support. The coach used a web-based tool to generate an education plan tailored to the patient's glaucoma diagnosis, test results, and ophthalmologist's recommendations (www.glaucomaeyeguide.org). The tool guided an MI-based conversation between coach and patient to identify barriers to adherence and possible solutions. Descriptive statistics were used to summarize baseline patient characteristics, and differences between those who did and did not complete the SEE program were tested with 2-sample t tests, chi-square tests, and Fisher exact tests. Adherence was compared before and after the SEE program with paired t tests.Main outcome measureChange in electronically monitored medication adherence.ResultsA total of 48 participants were enrolled. The participants were 54% male, 46% white, and on average 64 years of age (standard deviation [SD], 10.8 years), with an average worse-eye mean deviation (MD) of -7.9 dB (SD, 8.8 dB). Those completing the SEE program (n = 39) did not differ significantly from those who dropped out (n = 9) on gender, race, age, MD, or baseline adherence. Medication adherence improved from 59.9% at baseline to 81.3% (P < 0.0001) after completing the SEE program. Ninety-five percent of participants showed an improvement in adherence (mean relative improvement, 21.4%; SD, 16.5%; range, -3.2% to 74.4%; median, 20.1%). Fifty-nine percent of participants showed adherence of >80% on completing the SEE program.ConclusionsThe SEE program participants showed clinically meaningful, statistically significant improvement in glaucoma medication adherence.

Project description:BackgroundNon-adherence to essential medications represents an important public health problem. Little is known about the frequency with which patients fail to fill prescriptions when new medications are started ("primary non-adherence") or predictors of failure to fill.ObjectiveEvaluate primary non-adherence in community-based practices and identify predictors of non-adherence.Participants75,589 patients treated by 1,217 prescribers in the first year of a community-based e-prescribing initiative.DesignWe compiled all e-prescriptions written over a 12-month period and used filled claims to identify filled prescriptions. We calculated primary adherence and non-adherence rates for all e-prescriptions and for new medication starts and compared the rates across patient and medication characteristics. Using multivariable regressions analyses, we examined which characteristics were associated with non-adherence.Main measuresPrimary medication non-adherence.Key resultsOf 195,930 e-prescriptions, 151,837 (78%) were filled. Of 82,245 e-prescriptions for new medications, 58,984 (72%) were filled. Primary adherence rates were higher for prescriptions written by primary care specialists, especially pediatricians (84%). Patients aged 18 and younger filled prescriptions at the highest rate (87%). In multivariate analyses, medication class was the strongest predictor of adherence, and non-adherence was common for newly prescribed medications treating chronic conditions such as hypertension (28.4%), hyperlipidemia (28.2%), and diabetes (31.4%).ConclusionsMany e-prescriptions were not filled. Previous studies of medication non-adherence failed to capture these prescriptions. Efforts to increase primary adherence could dramatically improve the effectiveness of medication therapy. Interventions that target specific medication classes may be most effective.

Project description:BackgroundHypertension is a major risk factor for global disease burden, however, little is known regarding the profiles of patients with hypertension in Indonesian primary care settings.ObjectiveThis study aimed to profile medication use, adherence to medications and lifestyle modifications as well as blood pressure control among patients with hypertension in Indonesian primary health centres (PHCs).MethodsA cross-sectional study design used a structured data collection tool (questionnaire and checklist). Patients aged ≥18 years with a diagnosis of hypertension, and prescribed an antihypertensive medication, and attending follow-up visits in the five PHCs in Surabaya, Indonesia, during a two-week study period (May-October 2019) were included. Descriptive analyses summarised the data, while binary logistic regression provided any independent associations between adherence profiles and blood pressure control.ResultsOf 457 eligible patients, 276 patients consented: PHC A (n = 50/91), PHC B (n = 65/116), PHC C (n = 47/61), PHC D (n = 60/88), PHC E (n = 54/101), giving an overall response rate of 60.4%. Patients were mainly treated with a single antihypertensive medication, i.e., amlodipine (89.1%), and many had not achieved blood pressure targets (68.1%). A majority reported notable levels of non-adherence to medication (low/intermediate, 65.2%) and poor healthy lifestyle behaviours, particularly physical activity (inadequate, 87.7%) and discretionary salt use (regularly, 50.4%). Significant associations were found between low medication adherence, discretionary salt use and smoking, with blood pressure control.ConclusionsThe study findings provide the evidence needed to improve the current level of sub-optimal blood pressure management among patients with hypertension in these Indonesian primary care settings. Particular emphasis should be placed on antihypertensive medication adherence and healthy lifestyle behaviours through locally tailored hypertension-related interventions.

Project description:This systematic review applied meta-analytic procedures to integrate primary research that examined theory- or model-linked medication adherence interventions.Extensive literature searching strategies were used to locate trials testing interventions with medication adherence behavior outcomes measured by electronic event monitoring, pharmacy refills, pill counts, and self-reports. Random-effects model analysis was used to calculate standardized mean difference effect sizes for medication adherence outcomes.Codable data were extracted from 146 comparisons with 19,348 participants. The most common theories and models were social cognitive theory and motivational interviewing. The overall weighted effect size for all interventions comparing treatment and control participants was 0.294. The effect size for interventions based on single-theories was 0.323 and for multiple-theory interventions was 0.214. Effect sizes for individual theories and models ranged from 0.041 to 0.447. The largest effect sizes were for interventions based on the health belief model (0.477) and adult learning theory (0.443). The smallest effect sizes were for interventions based on PRECEDE (0.041) and self-regulation (0.118).These findings suggest that theory- and model-linked interventions have a significant but modest effect on medication adherence outcomes.

Project description:Race consciousness (the frequency with which one thinks about his or her own race) is a measure that may be useful in assessing whether racial discrimination negatively impacts blood pressure (BP). However, the relation between race consciousness and BP has yet to be empirically tested, especially within the context of the patient-physician relationship and medication adherence.Race-stratified generalized estimating equations were used to assess the relationship of race consciousness on BP, measures of the patient-physician relationship, and self-reported medication adherence, controlling for patients being nested within physicians and for patient age and sex.The mean age of the patients was 61.3 years, 62% were black, and 65% were women. Black patients were more likely to ever think about race than were white patients (49% vs. 21%; P < 0.001). Race-conscious blacks had significantly higher diastolic BP (79.4 vs. 74.5 mm Hg; P = 0.004) and somewhat higher systolic BP (138.8 vs. 134.7 mm Hg; P = 0.13) than blacks who were not race conscious. Race-conscious whites were more likely to perceive respect from their physician (57.1% vs. 25.8%; P = 0.01) but had lower medication adherence (62.4% vs. 82.9%; P = 0.05) than whites who were not race-conscious.Among blacks, race consciousness was associated with higher diastolic BP. In contrast, among whites, there was no association between race consciousness and BP, but race consciousness was associated with poor ratings of adherence, despite more favorable ratings of the patient-physician relationship. Future work should explore disparities in race consciousness and its impact on health and health-care disparities.
