The Impact of the Support, Educate, Empower Personalized Glaucoma Coaching Pilot Study on Glaucoma Medication Adherence.

ABSTRACT:

Purpose

To assess the efficacy of the Support, Educate, Empower (SEE) glaucoma coaching program on medication adherence among glaucoma patients with low adherence.

Design

Uncontrolled intervention study with a pre-post design.

Participants

Glaucoma 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.

Methods

Participants' 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 measure

Change in electronically monitored medication adherence.

Results

A 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.

Conclusions

The SEE program participants showed clinically meaningful, statistically significant improvement in glaucoma medication adherence.

Project description:PurposeTo understand patients' qualitative experiences with the Support, Educate, Empower (SEE) personalized glaucoma coaching program, provide a richer understanding of the components of the intervention that were useful in eliciting behavior change, and understand how to improve the SEE Program.DesignA concurrent mixed-methods process analysis.ParticipantsThirty-nine patients with a diagnosis of any kind of glaucoma or ocular hypertension who were aged ≥40 years, were taking ≥1 glaucoma medication, spoke English, self-administered their eye drops, and had poor glaucoma medication adherence (defined as taking ≤80% of prescribed medication doses assessed via electronic medication adherence monitors) who completed the 7-month SEE Program.MethodsAll participants who completed the study were interviewed in-person using a semistructured interview guide after the intervention. Coders conducted qualitative analysis of transcribed interviews using Grounded Theory. Participants were then stratified into groups based on change in adherence, and thematic differences between groups were examined.Main outcome measuresThemes that emerged from interviews categorized by the number of participants who expressed a theme and the number of representative citations.ResultsParticipants expressed positive views toward the program overall (95%, n = 37/39). They perceived program components as working together to improve their medication adherence. Interactions with the glaucoma coach (38 participants, 184 citations), motivation to aid personal change (38 participants, 157 citations), personalized glaucoma education (38 participants, 149 citations), electronic reminders, and hearing their adherence score (37 participants, 90 citations) were most commonly cited by participants as helpful program elements contributing to improved adherence. Patients expressed a desire for personalized education to be a standard part of glaucoma care. Participants who demonstrated more improvement in adherence had a more trusting attitude toward the adherence score and a greater magnitude of perceived personal need to improve adherence.ConclusionsParticipants reported a highly positive response to the in-person glaucoma education and motivational interviewing intervention used in conjunction with automated adherence reminders.

Project description:PurposeTo assess the Support, Educate, Empower (SEE) personalized glaucoma coaching program impact on (1) eye drop instillation technique and (2) eye drop instillation self-efficacy.DesignProspective pre-post pilot study.ParticipantsPatients with a diagnosis of glaucoma or ocular hypertension taking ≥1 glaucoma medication, ≥40 years old, spoke English, self-administered their eye drops, and ≤80% adherent to their glaucoma medication by electronic monitoring.MethodsEye drop administration was video recorded before the first SEE in-person coaching session, which included teaching eye drop instillation techniques using a motivational interviewing-based approach. At the third and final in-person counseling session 6 months later, eye drop administration was video recorded. Participants' self-efficacy was assessed using the validated Eye Drop Technique Self-Efficacy Scale (EDTSES) survey at baseline and 1 month after completion of the program. Before and after intervention videos were assessed by an observer masked to time point. Before versus after intervention comparisons were made using McNemar's and paired t tests.Main outcome measuresThe main outcome was change in participants' eye drop instillation technique as measured by (1) accuracy of an eye drop landing on the eye, (2) ability to instill an eye drop on the first attempt, and (3) contaminating the bottle by contact with ocular surface, eyelashes, and skin. The secondary outcome measure was before versus after change in the EDTSES score (6 items, each assessed on a 3-point Likert scale, with higher scores indicating better self-efficacy).ResultsThirty-nine participants completed the SEE intervention, 38 with before and after EDTSES scores and 31 with video recordings. Six of 31 participants instilling drops outside the eye before intervention improved their technique after intervention, whereas 2 participants worsened (P = 0.157). From before to after intervention, participants demonstrated significant improvement in not touching the ocular surface (P = 0.046), the eyelashes (P = 0.020), or the skin (P = 0.025) with the bottle tip. A significant increase was found in eye drop instillation self-efficacy from an average score of 2.6 (standard deviation [SD], 0.3) to 2.8 (SD, 0.2) on the EDTSES score (P = 0.007).ConclusionsThe SEE program significantly decreased eye drop bottle contamination, increased eye drop instillation self-efficacy, and demonstrated an insignificant increase in ability to instill drops successfully and accurately.

Project description:PrecisHigher levels of near vision-related quality of life (VRQoL) were associated with higher adherence to glaucoma medications after adjusting for important confounding variables among participants in the Support, Educate, Empower (SEE) personalized glaucoma coaching pilot study.PurposeTo investigate the association between VRQoL and glaucoma medication adherence.Materials and methodsSubjects were recruited for the SEE program, a prospective noncontrolled cohort study examining the impact of a personalized coaching program on glaucoma medication adherence. Glaucoma patients seen at the University of Michigan over 40 years old, taking ≥1 glaucoma medication, and self-reported poor adherence on 2 validated scales were recruited. Demographic details and VRQoL using the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25) were collected. Participants' medication use for each prescribed glaucoma medication was captured electronically using a medication events monitoring system. The association between VRQoL and medication adherence was assessed with Pearson correlation coefficient (r) and linear regression.ResultsAmong the 95 eligible participants 49.5% were female, 55.3% were Caucasian, and mean age (±SD) was 63.8±10.5 years. Mean adherence to glaucoma medication was 73.8%±21.0%. Mean NEI VFQ-25 composite score was 81.6±14.5. Better medication adherence was significantly and positively correlated with better functioning in domains of ocular pain (r=0.20, P=0.048), near activities (r=0.29, P=0.004), and role difficulties (r=0.22, P=0.036). Linear regression models adjusting for known correlates of medication adherence (age, sex, race, income), showed a 10-unit increase in self-perceived near activities function was associated with a 2.2% increase in medication adherence (95% confidence interval, 1.0%-5.4%; P=0.0056).ConclusionBetter self-perceived near activities function was associated with increased glaucoma medication adherence.

Project description:PurposeTo investigate whether demographic, clinical, or psychosocial factors act as moderators of change in medication adherence in the Support, Educate, Empower (SEE) program.DesignProspective, single-arm pilot study with a pre-post design.ParticipantsPatients with glaucoma aged ≥ 40 years and taking ≥ 1 glaucoma medication were recruited from the University of Michigan Kellogg Eye Center. Those who had electronically measured adherence ≤ 80% in the 3-month eligibility monitoring period were enrolled in the SEE program.MethodsMedication adherence was monitored electronically during the 7-month intervention and calculated as the percentage of doses taken correctly. Change in adherence at different points in the SEE program and cumulative change in adherence were modeled with linear regression, and baseline demographic, clinical, and psychosocial factors were investigated for significant associations.Main outcome measuresDemographic, clinical, and psychosocial variables associated with change in medication adherence in the SEE program.ResultsThirty-nine participants completed the SEE program. These participants were on average 63.9 years old (standard deviation [SD], 10.7 years), 56% (n = 22) were male, 44% (n = 17) were White, and 49% (n = 19) were Black. Medication adherence improved from an average of 59.9% (SD, 18.5%) at baseline to 83.6% (SD, 17.5%) after the final SEE session, for an increase of 23.7% (SD, 17.5%). Although participants with lower income (< $25 000 and $25 000-50 000 vs. >$50 000) had lower baseline adherence (48.4% and 64.1% vs. 70.4%), these individuals had greater increases in adherence during the first month of medication reminders (19.6% and 21.6% vs. 10.2%; P = 0.05 and P = 0.007, respectively). Participants taking fewer glaucoma medications also had significantly greater increases in adherence with medication reminders (P < 0.001). Those with higher levels of glaucoma-related distress (GD) had lower baseline adherence and greater increases in adherence with glaucoma coaching (P = 0.06).ConclusionsPatient-level factors associated with relatively greater improvements in medication adherence through the SEE Program included lower income, fewer glaucoma medications, and increased GD. These findings demonstrate that the SEE program can improve glaucoma self-management even among participants with social and psychological barriers to medication adherence.

Project description:PurposeTo assess possible changes in medication adherence to prostaglandin analog (PGA) regimens among patients with open-angle glaucoma (OAG) after the initial introduction of generic PGAs.DesignLongitudinal cohort analysis.ParticipantsPatients older than 40 years with OAG continuously enrolled in a nationwide managed-care network during 2009-2012 who used PGAs.MethodsMean adherence rates were calculated for topical PGA use during the 18 months before the introduction of generic latanoprost (September 2009-February 2011) and the 18 months after generic latanoprost became available (July 2011-December 2012). The rates were compared between persons who continued to use brand-name PGAs once generic latanoprost became available and others who switched to generic latanoprost. Multivariable logistic regression identified variables associated with an improvement or worsening of adherence of ≥25%.Main outcome measuresMean adherence rates and odds of 25% or more improved or worsened adherence (with 95% confidence intervals [CIs]).ResultsA total of 8427 patients met the study eligibility criteria. Compared with persons switching to generic latanoprost, patients who continued taking brand name PGAs were 28% less likely to have improved adherence (odds ratio [OR], 0.72; 95% CI, 0.55-0.94) and 39% more likely to have reduced adherence (OR, 1.39; 1.04-1.86) of ≥25%. Improved adherence after the generic drug's introduction was also associated with higher monthly medication copay in the pregeneric period (P = 0.02), lower copay after introduction of the generic drug (P < 0.0001), and black race (OR, 1.25; 95% CI, 1.04-1.50). Six-hundred twelve patients (7.3%) discontinued all antiglaucoma interventions when generic latanoprost became available.ConclusionsGiven that cost can significantly deter adherence, switching patients to generic medications may help improve patients' drug-regimen adherence. A considerable number of patients discontinued glaucoma drug use altogether when generic latanoprost became available. Ophthalmologists should work with insurers and pharmacists to prevent such discontinuation of use as generic forms of other PGA agents become available.

Project description:PurposeThe majority of patients with glaucoma do not take their medications as prescribed. Estimates of the cost-utility value of adherence to prescribed glaucoma medication are vital to implement potentially effective interventions.DesignCost-utility analysis using Monte Carlo microsimulations incorporating a series of Markov cycles (10 000 iterations per strategy).ParticipantsPatients with glaucoma aged ≥40 years with a full lifetime horizon (up to 60 years).MethodsThe analysis estimated glaucomatous progression on the basis of data from the United Kingdom Glaucoma Treatment Study. Participants with glaucoma entered the model at age 40 years with a mean deviation in the better-seeing eye of -1.4±-1.9 decibels (dB) and -4.3±-3.4 dB in the worse-seeing eye. Participants whose glaucoma worsened each year accumulate -0.8 dB loss compared with -0.1 dB loss for those who remained stable. Data from the Glaucoma Laser Trial and the Tube versus Trabeculectomy Studies were used to assign probabilities of worsening disease among treated patients. Claims data estimating rates of glaucoma medication adherence over 4 years were used to assign probability of adherence. Those with poor adherence were modeled as having outcomes similar to the placebo arm of the clinical trials. As patients' mean deviation deteriorated, they transitioned between health states from mild (≥-6 dB), to moderate (<-6 to ≥-12 dB), to severe glaucoma (<-12 to ≥23 dB), to unilateral (<-20 dB) and bilateral blindness. At each health state, patients incurred the costs of treatment and established health utilities; ultimately, societal costs of low vision and blindness were included.Main outcome measuresCost and quality-adjusted life year (QALY) of glaucoma medication adherence.ResultsBeginning at an initial glaucoma diagnosis at age 40 years, patients proceeded to single-eye blindness as early as 19 years among those who were nonadherent and 23 years for those remaining adherent. Total healthcare costs for adherent patients averaged $62 782 (standard deviation [SD], 34 107), and those for nonadherent patients averaged $52 722 (SD, 38 868). Nonadherent patients had a mean loss of 0.34 QALYs, resulting in a cost-effectiveness ratio of $29 600 per QALY gained.ConclusionAt a conservative willingness to pay of $50 000/QALY, there is room to expand services to improve patient adherence.

Project description:To determine the associations between medical, demographic, socioeconomic, and ocular factors and adherence to topical glaucoma ocular hypotensive therapy.One hundred sixteen patients with ocular hypertension or open-angle glaucoma from 2 tertiary glaucoma services participated in this prospective study. Adherence to ocular hypotensive therapy was measured using an electronic dose monitor (Travatan Dosing Aid, Alcon Laboratories Inc., Fort Worth, TX) and collected data at 3 months after enrollment. We used 3 different definitions of adherence: 1) Definition 1: the proportion of days taking the prescribed number of drops within 3 hours of the prescribed dosing time; 2) Definition 2: the proportion of days taking any drops within 3 hours of the prescribed dosing time; and 3) Definition 3: the proportion of days taking any drops within 6 hours of the prescribed dosing time. Univariate and multivariate models were used to determine the association between the 3 adherence definitions, medical, demographic, socioeconomic, and ocular factors at 3-month follow-up. The main outcome measures for this study were risk factors for poor objective medication adherence.Adherence, using Definition 1, Definition 2, and Definition 3, was 64%, 75%, and 80%, respectively. Age, total number of other eye diseases, and race were significantly associated with full treatment adherence (Definition 1), with race alone significantly predicting 11% of full treatment adherence. For Definition 2, age, income, level of education, and total number of eye diseases were significantly associated with partial adherence (3 h), again race alone significantly predicted 15% of partial adherence (any drops within 3 h). For Definition 3, race, income, level of education, and total number of other eye diseases significantly predicted partial adherence (any drops within 6 h), both race and income predicted 19% of partial treatment adherence. Significant differences for adherence rates between patients of European descent and those of African descent were found for all 3 definitions with those who were less adherent more likely to be of African descent.Electronic dose monitors provide important information regarding adherence to topical ocular hypotensive medications in glaucoma patients. Electronic dose monitors show low adherence in a significant number of participants. Future studies are needed to determine the reasons for these differences in health behaviors related to glaucoma treatment, which should guide treatment of poor adherence with glaucoma therapy.

Project description:PurposeTo assess the accuracy of 5 subjective self-assessment tools (3 adherence measures and 2 psychometric scales) and pharmacy refill data in predicting objective electronically monitored nonadherence.DesignProspective cohort study.ParticipantsGlaucoma patients (> 40 years old, >1 medication with poor self-reported adherence) were recruited from University of Michigan Kellogg Eye Center for a study assessing the impact of a personalized glaucoma coaching program on medication adherence.MethodsParticipants completed an initial assessment including 5 self-assessment tools and a 3-month period of electronic monitoring of glaucoma medication adherence (AdhereTech); pharmacy refill data were obtained. Electronically monitored adherence was calculated monthly as the percentage of doses taken on time. The median of these adherence rates was designated as baseline adherence. Patients with adherence of ≤80% by electronic monitoring were considered nonadherent. Self-assessment tools were scored, and pharmacy refill data were summarized as the proportion of days covered. Correlation between measures of adherence was estimated with Pearson and Spearman correlation coefficients. Receiver operating characteristic curves, including estimation of area under the curve (AUC), sensitivity, specificity, and accuracy were used to compare measures of adherence with respect to predicting electronically monitored nonadherence.Main outcome measuresAccuracy of self-reported and pharmacy refill data adherence measures in predicting electronically monitored nonadherence.ResultsNinety-five patients completed 3 months of electronic monitoring with a median monthly adherence of 74 (± 21%); 53 patients (56%) were nonadherent. Pharmacy refill data were not correlated significantly with electronically monitored medication adherence (r = 0.12; P = 0.2). Of all the measures, a single-item adherence question ("Over the past month, what percentage of your drops do you think you took correctly?") showed the largest correlation with median electronically monitored adherence (r = 0.47; P < 0.0001), largest AUC for predicting nonadherence (AUC = 0.76 [95% confidence interval [CI], 0.66-0.87]), best accuracy (71% [95% CI, 61%-82%]), and good sensitivity (84% [95% CI, 73%-96%]).ConclusionsThe single-item question was the most accurate in predicting electronically monitored nonadherence among participants with poor self-reported adherence. In clinical practice, where alternatives are too resource intensive, this free single-item screening question can help to identify glaucoma patients at risk of poor medication adherence with reasonable accuracy.

Project description:BackgroundMany glaucoma patients do not adhere to their medication regimens because they fail to internalize the (health) costs of non-adherence, which may not occur until years or decades later. Behavioural economic theory suggests that adherence rates can be improved by offering patients a near-term benefit. Our proposed strategy is to offer adherence-contingent rebates on medication and check-up costs. This form of value pricing (VP) ensures that rebates are granted only to those most likely to benefit. Moreover, by leveraging loss aversion, rebates are expected to generate a stronger behavioural response than equivalent financial rewards.Methods/designThe main objective of the Study on Incentives for Glaucoma Medication Adherence (SIGMA) is to test the VP approach relative to usual care (UC) in improving medication adherence. SIGMA is a randomized, controlled, open-label, single-centre superiority trial with two parallel arms. A total of 100 non-adherent (Morisky Medication Adherence Scale ≤6) glaucoma patients from the Singapore National Eye Centre are block-randomized (blocking factor: single versus multiple medications users) into the VP and UC arms in a 1:1 ratio. The treatment received by VP patients will be strictly identical to that received by UC patients, with the only exception being that VP patients can earn either a 50 % or 25 % rebate on their glaucoma-related healthcare costs conditional on being adherent on at least 90 % or 75 % of days as measured by a medication event monitoring system. Masking the arm allocation will be precluded by the behavioural nature of the intervention but blocking size will not be disclosed to protect concealment. The primary outcome is the mean change from baseline in percentage of adherent days at month 6. A day will be counted as adherent when the patients take all their medication(s) within the appropriate dosing windows.DiscussionThis trial will provide evidence on whether adherence-contingent rebates can improve medication adherence among non-adherent glaucoma patients, and more generally whether this approach represents a promising strategy to cost-effectively improve chronic disease management.Trial registrationNCT02271269 .
