Glaucoma Disease-Specific Adherence Measurement Tools Validated for Measuring Adherence to Glaucoma Medications: A Systematic Review. Health Sci Rep 2025; 8:e70427. [PMID: 39931261 PMCID: PMC11808388 DOI: 10.1002/hsr2.70427] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2024] [Revised: 12/20/2024] [Accepted: 01/20/2025] [Indexed: 02/13/2025] Open
Abstract
Background Reviewing validated glaucoma disease-specific tools for measuring adherence could encourage adherence monitoring to avoid progressive visual field losses in people living with glaucoma. Aim To review the literature on validated disease-specific tools for measuring adherence to glaucoma medications. Methods Relevant peer-reviewed publications from the year 2000 to 2022 from PubMed, EMBASE, Scopus, and PROquest were retrieved. For each search conducted, the name of the search engine used, date of search, number of publications retrieved, and keywords used were documented. The selected articles were reviewed for inclusion and assessed for biases and quality. Each tool was described by the type of measurement, technique for measurement, strengths and weaknesses, and method of validation, respectively. Results Out of the 10 included articles, seven glaucoma disease-specific tools were identified namely; Glaucoma Treatment Compliance Assessment Tool-Short form (GTCAT-S), Glaucoma Treatment Compliance Assessment Tool-Long form (GTCAT-L), Travatan Dosing Aid (TDA), Eye-Drop Satisfaction Questionnaire (EDSQ), Glaucoma Adherence Questionnaire-Revised (GAQ-R), Glaucoma Adherence Questionnaire-Old (GAQ-O), and Schwartz Adherence Questionnaire (SAQ). Three studies had a low risk of bias, and seven recorded a moderate risk of bias. The TDA, GTCAT-S, and GTCAT-L were rated as high-quality tools. Conclusions Seven glaucoma disease-specific tools for measuring adherence were found. Integration of regular measurement of medication adherence as part of care for glaucoma patients would be beneficial for both patients and providers of eye care.

Abstract
Prospective cohort study from Brazil to evaluate glaucoma treatment adherence using a medication event monitoring system (MEMS) device and correlate with glaucoma progression and loss to follow-up (LTF) after one year of follow up. We included primary open glaucoma (POAG) patients treated with at least one ocular hypotensive eye drop. MEMS devices was used to monitor adherence for 60 days and evaluate the percentage of doses prescribed taken within the 60-day period. We classified patients according to rates of adherence: low adherence (less than 75% from MEMS measurements) and high adherence (more than 75% from MEMS measurements). We applied a questionnaire to investigated self-reported behavior towards treatment behaviors (glaucoma treatment compliance assessment tool, GTCAT). We also correlated rates of treatment adherence with clinical, demographical variables and the occurrence of glaucoma progression or LTF after one year of observation. We included 110 POAG patients and found that 28.18% of them were considered low adherent. We identify several variables associated with poor adherence such as glaucoma progression, LTF, younger age, low educational and income levels, absence of health insurance, years of disease and peak intraocular pressure. Several constructs from the self-reported GTCAT were also correlated with the rates of treatment adherence. To date, this is the first study in Latin America to evaluate glaucoma treatment adherence with MEMS devices and correlate adherence rates with glaucoma progression and LTF. We found a low-adherence rate of 28.18% and several additional risk factors were statistically associated with poor adherence.

Abstract
Glaucoma is a leading cause of vision loss. First line therapy for primary open angle glaucoma (POAG) are topical ocular hypotensive drops. Patient adherence with topical therapy for glaucoma is a significant challenge with a reported adherence of 60%. The purpose of this review is to discuss factors associated with glaucoma adherence (including demographic factors, cost, patient education, health beliefs, treatment burden and regimen, and physical limitations) and to explore potential interventions to improve medication adherence. Articles included in this review were found by searching PubMed and Google Scholar using the key words "Glaucoma Treatment Adherence" and "Glaucoma Treatment Compliance." Data from this review demonstrates that higher medication cost, lower patient education/literacy levels, and being of African and Hispanic descent are associated with lower medication adherence rates. The data is inconclusive on whether medication regimen complexity lowers patient medication adherence rates. Interventions that have successfully improved medication adherence rates for minority patients have focused on building trust and addressing fears and false beliefs. For cost, explicit physician communication to patients regarding medication cost is important and can help the physician determine any patient concerns about cost. Outside the USA, adherence has been improved through adherence-contingent rebate systems and government subsidies. Most interventions that aim to increase adherence target patient education and literacy with the following interventions demonstrating efficacy: written instructions targeting glaucoma-specific health literacy, literacy level appropriate glaucoma education videos, and interactive and personalized educational programs. More clinic infrastructure and programs that utilize patient reminder tools and patient educators could help physicians and patients in support of these personalized action plans.

Abstract
PRCIS Self-determination theory (SDT) guided behavioral interventions are effective in improving several patient-centered metrics, including glaucoma-related distress. However, whether improvement in patient-centered metrics can drive an improvement in medication-taking behavior remains to be seen. OBJECTIVE The 7-month Support, Educate, Empower (SEE) personalized glaucoma coaching program was previously shown to improve glaucoma medication adherence by 21 percent points. This study's goal was to assess the impact of the SEE program on self-determination theory (SDT) metrics and other patient-centered outcome measures. PARTICIPANTS AND METHODS Glaucoma patients (≥40 y old, taking ≥1 medication) self-reporting poor medication adherence were recruited at the University of Michigan. Eight surveys (with 10 subscales) were completed before and after the 7-month SEE program. Three surveys assessed changes in SDT (Treatment Self-regulation Questionnaire, Healthcare-Climate Questionnaire, Perceived Competence) while the others assessed participants' Glaucoma Knowledge, Glaucoma Medication Self-efficacy, Glaucoma-related distress, Perceived benefits, confidence asking and getting questions answered. RESULTS Thirty-nine participants completed the SEE program. Significant improvements were in 7 subscales, including all three SDT tenets of competence (mean change =0.9, SD =±1.2, adjusted P =0.0002), autonomy (0.5, ±0.9, 0.044), and relatedness ( P =0.002). Glaucoma-related distress (-2.0, ±3.2, 0.004), confidence in asking questions (1.1, ±2.0, 0.008), and confidence in getting questions answered (1.0, ±2.0, 0.009) also improved. Glaucoma-related distress was correlated with perceived competence ( r =-0.56, adjusted P =0.005), and an increase in perceived competence was associated with a decrease in glaucoma-related distress (β=-0.43, 95% CI -0.67 - -0.20, adjusted P =0.007). CONCLUSIONS The SEE program improved participants' autonomous motivation, perceived support, perceived competence, glaucoma-related distress, and competence. These results point to the promising potential of SDT-guided behavioral interventions in improving patient-centered metrics.

Abstract
PURPOSE Over 50% of breast cancer patients prescribed a 5-year course of daily oral adjuvant endocrine therapy (ET) are nonadherent. We investigated the role of costs and cancer medication delivery mode and other medication delivery factors on adherence. METHODS We conducted a retrospective cohort study of commercially insured and Medicare advantage patients with newly diagnosed breast cancer in 2007-2015 who initiated ET. We examined the association between 12-month ET adherence (proportion of days covered by fills ≥ 0.80) and ET copayments, 90-day prescription refill use, mail order pharmacy use, number of pharmacies, and synchronization of medications. We used regression models to estimate nonadherence risk ratios adjusted for demographics (age, income, race, urbanicity), comorbidities, total medications, primary cancer treatments, and generic AI availability. Sensitivity analyses were conducted using alternative specifications for independent variables. RESULTS Mail order users had higher adherence in both commercial and Medicare-insured cohorts. Commercially insured patients who used mail order were more likely to be adherent if they had low copayments (< $5) and 90-day prescription refills. For commercially insured patients who used local pharmacies, use of one pharmacy and better synchronized refills were also associated with adherence. Among Medicare patients who used mail order pharmacies, only low copayments were associated with adherence, while among Medicare patients using local pharmacies both low copayments and 90-day prescriptions were associated with ET adherence. CONCLUSION Out-of-pocket costs, medication delivery mode, and other pharmacy-related medication delivery factors are associated with adherence to breast cancer ET. Future work should investigate whether interventions aimed at streamlining medication delivery could improve adherence for breast cancer patients.

Abstract
Purpose To investigate whether the planning of selective laser trabeculoplasty (SLT) influences the intraocular pressure (IOP) in patients with open angle glaucoma (OAG). Methods In this retrospective case-control study conducted on patients with OAG who planned to undergo SLT treatment (SLT group) or a visual field examination (VF group), we collected the demographic data, IOP on the planning day and on the scheduled day of the SLT treatment or VF examination. ΔIOP was defined as the IOP change between the planning day and the scheduled day. We used multivariable regression analyses and linear mixed model to evaluate the association between the abovementioned factors and ΔIOP in the VF group and the treatment eye (SLTt) and fellow eye (SLTf) of the SLT group. Results One hundred and fifty-three eyes of 102 patients with OAG were included, of which 51 patients in the SLT group and 51 patients in the VF group. The ΔIOP was −1.92 ± 2.77 mmHg in the SLTt, −0.65 ± 2.47 mmHg in the SLTf and −0.08 ± 1.73 mmHg in the VF group (P < 0.05). Both multivariable regression analysis between the VF and SLTt group and linear mixed model in the SLT group showed significant negative association between the ΔIOP and SLT arrangement (P < 0.05). There was no significant association between ΔIOP and age, gender, baseline IOP, IOP fluctuation, nor SE. Conclusions The IOP was significantly reduced in patients with OAG after “planning” of SLT treatment, even without actual performing the laser treatment in our retrospective case-control study.

Abstract
TOPIC Comparative effectiveness of interventions to improve glaucoma medication adherence. CLINICAL RELEVANCE High adherence to ocular hypotensive therapy is essential for prevention of visual impairment in glaucoma patients. Various types of intervention for adherence enhancement have been proposed, although there is still no firm evidence of their relative efficacies. METHODS We searched PubMed, EMBASE, Scopus, the Cochrane Central Register of Controlled Trials, the World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov on November 30, 2021. Randomized controlled trials (RCTs) entailing interventions for improved adherence to ocular hypotensive therapy were identified. A network meta-analysis (NMA) was performed, and the following 11 interventions (single category or combinations of categories) were compared: (1) standard of care ([SOC] control), (2) short message service, (3) telephone call, (4) device reminder, (5) motivational interview, (6) multimedia education, (7) physician education, (8) provision of own medical records, (9) incentives, (10) tailored care, and (11) enhanced SOC. The primary outcome was the postintervention mean adherence score. The standardized mean differences (SMDs) were analyzed, and the effectiveness was ranked by P-score (probability of being best treatment). We appraised trials using the Cochrane risk-of-bias tool for RCTs. Confidence of results was assessed by Confidence in Network Meta-analysis. RESULTS We obtained data for 19 RCTs (4981 participants). Tailored care, as inclusive of face-to-face needs assessment and a personalized care plan, was superior to SOC in improving adherence (SMD, 1.28; 95% confidence interval [CI], 0.08-2.48; P-score, 0.810). Multifaceted interventions that included tailored care showed further adherence improvement: tailored care + multimedia education (SMD, 1.44; 95% CI, 0.20-2.67; 0.850) and tailored care + multimedia education + device reminder (SMD, 1.61; 95% CI, 0.75-2.47; 0.914). The ranking of the remaining interventions by P-scores was as follows: incentives (0.606), short message service (0.535), enhanced SOC (0.458), multimedia education (0.430), device reminder (0.429), telephone call (0.401), provision of own medical records (0.391), physician education (0.281), SOC (0.230), and motivational interview (0.165). CONCLUSIONS The NMA indicated that tailored care can improve adherence to glaucoma medication compared with SOC. A multifaceted approach might yield additional improvements.

Abstract
Background Glaucoma is one of the most common eye diseases in the elderly and the major cause of irreversible vision loss worldwide. Adherence to life-long therapies is crucial to prevent glaucoma progression. The current study aims to assess the educational element and its impact on glaucoma medication compliance over short and long periods. Methods This was a survey-based, prospective, interventional study, conducted via interviews of all glaucoma patients presented to the Ophthalmology Center at King Abdullah Medical City (KAMC), Makkah, Saudi Arabia. To achieve the study's aim, a questionnaire with 31 items was utilized, followed by a structured program between September 2019 to June 2021. After that, a second questionnaire was used after a one month to one year to re-evaluate the intervention. Data was automatically collected in Microsoft Excel (Microsoft Corporation, Redmond, Washington, United States) and entered into IBM SPSS Statistics for Windows, Version 22.0 (Released 2013; IBM Corp., Armonk, New York, United States) for analysis. Results Non-compliance was detected in 15.7% of all recruited patients (n=134). However, the non-compliance percentage dropped to 10 (7.5%) after the structured program (P=0.028). Contributing factors were low educational level, bilateral eye disease, duration of treatment more than two years, and having more than two eye treatment bottles; however, the P-value was insignificant. Conclusions About one-sixth of our glaucoma patients were found to be non-compliant. However, the non-compliance reduced by more than half after the structured educational program. Treatment adherence can be improved by implementing awareness and correcting the beliefs about illness and medicines, thus potentially delaying disease development.

Abstract
PURPOSE To evaluate the quality, reliability, and popularity of videos relating to glaucoma on YouTube. DESIGN Retrospective, cross-sectional study of YouTube videos about glaucoma. PARTICIPANTS One hundred YouTube videos were analyzed for this study. METHODS An online YouTube search for glaucoma videos was conducted simulating a user search using the keywords glaucoma, high eye pressure, and high intraocular pressure. The first 100 videos were analyzed, and each video was evaluated by 2 independent reviewers using the modified DISCERN (scale, 1-5), Journal of the American Medical Association (JAMA; scale, 0-4), and Global Quality (GQ; scale, 1-5) criteria to assess quality and reliability. Videos were categorized further into 3 groups depending on the source of their upload. Group 1 comprised videos uploaded by academic or government institutions, group 2 comprised videos uploaded by private medical practices, and group 3 comprised videos uploaded by independent users. MAIN OUTCOME MEASURES Modified DISCERN, JAMA, and GQ scores for quality and reliability of information and video power index (VPI) for video popularity. RESULTS No substantial difference in scoring was observed between the 2 independent reviewers. The overall mean ± standard error (SE) scores were modified DISCERN score, 3.81 ± 0.06; JAMA score, 2.93 ± 0.07; and GQ score, 3.98 ± 0.06. The overall mean ± SE VPI score was 9.9 ± 2.9. Significant positive correlations were found between video popularity and quality of information for all 3 criteria (P < 0.05). The videos in groups 1 and 2 showed higher modified DISCERN scores than those in group 3, but did not score higher with either the JAMA or GQ criteria. Videos in group 3 were the most popular when compared with videos in groups 1 or 2 (P < 0.01). CONCLUSIONS Overall, many of the videos had adequate quality and reliability scores. No difference was found among groups 1 through 3 for 2 of the 3 criteria used, suggesting a similar quality of information provided among academic, private, and independent sources.

Abstract
Abstract
Background
Treatment of open angle glaucoma (OAG) and/or ocular hypertension (OHT) focuses on achievement of target intraocular pressure (IOP), with the objective of slowing disease progression. However, ocular surface health is an important consideration in the optimization of treatment. We report 6 patient cases in which enhanced IOP control was achieved following appropriate management of ocular surface inflammation and a therapeutic switch to the preservative-free (PF) tafluprost (0.0015%)/timolol (0.5%) fixed-dose combination (FC).
Case presentation
Six patient cases, aged 48–74 years, presented with OAG or OHT. Each patient had signs and symptoms of ocular surface disease (OSD). Cases 1–3 were each receiving maximal medical therapy for OAG; regimens comprising prostaglandin analogue (PGA), β-blocker, carbonic anhydrase inhibitor (CAI) and α-2 agonist agents (including treatments containing preservative agent). Cases 1 and 2 reported IOP values ≥23 mmHg in each eye, and wide IOP fluctuations were identified when reviewing patient data concerning case 3 (11–20 mmHg). Maximal therapy was ceased and PF tafluprost/timolol FC was initiated, after which the signs and symptoms of OSD were improved and IOP was reduced (≤18 mmHg for cases 1–3) and stabilized. Cases 4 and 5 were diagnosed with OAG and case 6 had OHT. Each had symptoms and signs of OSD and were treated with a preserved PGA monotherapy (latanoprost 0.005% or bimatoprost 0.03%). At presentation, IOP was 24 mmHg in both eyes (case 4), ≥18 mmHg (case 5) and ≥ 22 mmHg (case 6). Following a switch to the PF tafluprost/timolol FC, OSD symptoms were improved and IOP was 14 mmHg (both eyes; case 4), ≤14 mmHg (case 5) and 16 mmHg (both eyes; case 6).
Conclusions
In addition to IOP-lowering efficacy, approaches to the management of OAG and OHT should consider the impact of treatment tolerability and the susceptibility of these patients to OSD. The presence of ocular surface inflammation appears to be detrimental to adherence and therefore to the effectiveness of topical medications. Addressing OSD through the use of PF FC formations, such as the PF tafluprost/timolol FC, reduces exposure to potentially toxic agents and facilitates improvements in IOP control.

Abstract
Background Medication adherence in glaucoma patients remains sub-par despite proven benefits of regular administration. The objective was to analyze medication adherence before and after lifestyle counseling in patients with ocular hypertension (OHT) or primary open-angle glaucoma (POAG) (mild, moderate, severe). Methods Prospective cohort study from May to July 2018 at a single academic center. From 391 consecutive records, 247 were excluded based on exclusion criteria with 28 patients not meeting inclusion criteria resulting in the final sample of 116 patients (33 had OHT, 83 had POAG – 28 mild, 39 moderate, 16 severe). Scripted lifestyle counseling focusing on diet, exercise, vitamin intake, stress management, and medication adherence was administered by a team of trained medical students. Primary outcome measure was self-reported medication adherence, defined as not missing an eye drop administration in the past month. A 2–3 week follow-up with scripted telephone survey assessing medication adherence, diet, and exercise was collected. Results At baseline, in 116 patients, 59.5% were adherent to their medication with a breakdown of 42.4% OHT, 64.3% mild, 66.7% moderate, and 68.7% severe and an increasing trend in medication adherence was found across increasing disease severity (p=0.055). Of the 76 (65.5%) patients reached for follow-up, 17 (22.4%) became adherent following lifestyle counseling (p=0.02) increasing overall adherence to 78.9% from 62.5%. Conclusion In our study, comprehensive lifestyle counseling succeeded in increasing medication adherence in patients with OHT and POAG.

Abstract
PURPOSE To provide a comprehensive assessment of the strategies studied to date that focus on improving glaucoma medication adherence. METHODS A systematic review of the literature was conducted in MEDLINE (PubMed), Embase (Elsevier), and Scopus (Elsevier) from inception to March 1, 2021, of publications describing a device or strategy used to improve glaucoma medication adherence. RESULTS 42 studies described by 50 papers were included. Five categories were identified: reminder systems, medication simplifications, behavioral change programs, education, and alternative engagement strategies. CONCLUSION Most studies (40 of the 42) addressed the question of improved adherence directly, with 26 finding improved adherence. Notably, 14 examined the clinical effects of the intervention, either in terms of intraocular pressure (IOP) or visual fields. Only three found an improvement in IOP. None demonstrated a between group difference in visual field progression.

Abstract
PURPOSE Despite advances in glaucoma treatment options, patient adherence and compliance remain very low. The EyePhone© App is a free non-commercial reminder application designed specifically for the needs of glaucoma patients. In this study, we evaluated its usefulness in improving adherence to medical treatment among glaucoma patients. METHODS This is a prospective multicenter interventional study. Glaucoma patients were recruited from a tertiary center and a large community glaucoma service center. After a short explanation, the EyePhone© App was installed on their smartphone device, and the notifications for the current medical treatment were entered. After enrollment and at 1-month follow-up, subjects completed the Morisky Medication Adherence Scale (MMAS-8) and the Quality of Life and Glaucoma 17-item (GlauQOL-17) questionnaires for evaluation of adherence and QOL, respectively. RESULTS In the study, 133 patients (71 men and 62 women) aged 62±15.5 years and using 2.0±0.9 IOP-lowering drugs participated. The proportion of highly adherent subjects improved from 29.3% (39/133) at baseline to 42.1% (56/133) at follow-up (P < 0.001), and the proportion of poorly adherent subjects decreased from 29.3 (39/133) to 20.3% (27/133) at follow-up (P = 0.012). QOL also improved, as evidenced by a significant increase in the GlauQOL-17 score (P < 0.05). In a subgroup of patients for whom IOP measurements were available, IOP reduced by 0.92 mmHg (P = 0.069). CONCLUSIONS Significant improvements in glaucoma adherence and QOL were achieved among poorly adherent glaucoma patients after 1 month of using the EyePhone© App.

Abstract
The glaucomas form a heterogenous group of conditions, which collectively account for one of the most common irreversible causes of blindness worldwide. The only treatment, for which there is evidence, to stop or slow glaucomatous disease progression is to lower intraocular pressure (IOP); this is most often initially achieved with topical medication. Adherence to anti-glaucoma therapy is known to be low even when compared with adherence to therapy for other chronic conditions. We performed a PubMed search to review evidence as to how adherence to and persistence with anti-glaucoma medications might be improved. Approaches to improving adherence include technological (such as using smart drop bottles or automated reminders) use of instillation aids, improving communication with patient education and improving tolerability of eye drop formulations. There is limited short-term evidence that automated reminders can be effective and, unfortunately, instillation aids have not proved to be efficacious with respect to improving adherence. A range of factors have been identified which affect adherence and persistence, although only a multi-faceted approach has proven evidence of efficacy, compared to improved patient education alone. There is now a wider range of available preservative-free eye drops, which have been shown to be non-inferior in achieving IOP control, with fewer side effects and improved short-term adherence. Further studies relating to adherence are warranted, particularly given the projected increase in glaucoma prevalence worldwide.

Abstract
PURPOSE To evaluate the relationship between medication adherence and visual field progression in participants randomized to the medication arm of the Collaborative Initial Glaucoma Treatment Study (CIGTS). DESIGN The CIGTS was a randomized, multicenter clinical trial comparing initial treatment with topical medications to trabeculectomy for 607 participants with newly diagnosed glaucoma. PARTICIPANTS Three hundred seven participants randomized to the medication arm of the CIGTS. METHODS Participants were followed up at 6-month intervals for up to 10 years. Self-reported medication adherence and visual fields were measured. Medication adherence was assessed by telephone from responses to the question, "Did you happen to miss any dose of your medication yesterday?" The impact of medication adherence on mean deviation (MD) over time was assessed with a linear mixed regression model adjusting for the effects of baseline MD and age, cataract extraction, interactions, and time (through year 8, excluding time after crossover to surgery). Medication adherence was modeled as a cumulative sum of the number of prior visits where a missed dose of medication was reported. MAIN OUTCOME MEASURE Mean deviation over time. RESULTS Three hundred seven subjects (306 with adherence data) were randomized to treatment with topical medications and followed up for an average of 7.3 years (standard deviation, 2.3 years). One hundred forty-two subjects (46%) reported never missing a dose of medication over all available follow-up, 112 patients (37%) reported missing medication at up to one third of visits, 31 patients (10%) reported missing medication at one third to two thirds of visits, and 21 patients (7%) reported missing medication at more than two thirds of visits. Worse medication adherence was associated with loss of MD over time (P = 0.005). For subjects who reported never missing a dose of medication, the average predicted MD loss over 8 years was 0.62 dB, consistent with age-related loss (95% confidence interval [CI], 0.17-1.06; P = 0.007); subjects who reported missing medication doses at one third of visits had a loss of 1.42 dB (95% CI, 0.86-1.98; P < 0.0001); and subjects who reported missing medication doses at two thirds of visits showed a loss of 2.23 dB (95% CI, 1.19-3.26; P < 0.0001). CONCLUSIONS This longitudinal assessment demonstrated a statistically and clinically significant association between medication nonadherence and glaucomatous vision loss.

Abstract
BACKGROUND Poor adherence to medications is a global public health concern with substantial health and cost implications, especially for chronic conditions. In the USA, poor adherence is estimated to cause 125,000 deaths and cost $US100 billion annually. The most successful adherence-promoting strategies that have been identified so far have moderate effect, are relatively costly, and raise availability, feasibility, and/or scalability issues. OBJECTIVE The main objective of SIGMA (Study on Incentives for Glaucoma Medication Adherence) was to measure the effectiveness on medication adherence of a novel incentive strategy based on behavioral economics that we refer to as adherence-contingent rebates. These rebates offered patients a near-term benefit while leveraging loss aversion and regret and increasing the salience of adherence. METHODS SIGMA is a 6-month randomized, controlled, open-label, single-center superiority trial with two parallel arms. A total of 100 non-adherent glaucoma patients from the Singapore National Eye Centre were randomized into intervention (adherence-contingent rebates) and usual care (no rebates) arms in a 1:1 ratio. The primary outcome was the mean change from baseline in percentage of adherent days at Month 6. The trial registration number is NCT02271269 and a detailed study protocol has been published elsewhere. FINDINGS We found that participants who were offered adherence-contingent rebates were adherent to all their medications on 73.1% of the days after 6 months, which is 12.2 percentage points (p = 0.027) higher than in those not receiving the rebates after controlling for baseline differences. This better behavioral outcome was achieved by rebates averaging 8.07 Singapore dollars ($US5.94 as of 2 November 2017) per month during the intervention period. CONCLUSION This study shows that simultaneously leveraging several insights from behavioral economics can significantly improve medication adherence rates. The relatively low cost of the rebates and significant health and cost implications of medication non-adherence suggest that this strategy has the potential to cost-effectively improve health outcomes for many conditions.

Making medications stick: improving medication adherence by highlighting the personal health costs of non-compliance. ACTA ACUST UNITED AC 2019.

Abstract
AbstractPoor compliance of prescription medication is an ongoing public health crisis. Nearly half of patients do not take their medication as prescribed, harming their own health while also increasing public health care costs. Despite these detrimental consequences, prior research has struggled to establish cost-effective and scalable interventions to improve adherence rates. We suggest that one reason for the limited success of prior interventions is that they make the personal health costs of non-adherence insufficiently prominent, while a higher saliency of these costs may motivate patients to adhere more. In the current research, we test whether an intervention that makes the personal health costs of non-compliance more salient for patients will increase their medication adherence. To do so, we conducted a randomized controlled trial with 16,191 patients across 278 UK pharmacies over a 9-month time period and manipulated the perceived consequences of medication non-adherence. We find that patients who received a treatment highlighting the personal health costs of non-compliance were significantly more likely to adhere to their medication than three comparison groups (odds ratio = 1.84, 95% confidence interval = 1.37–2.47). Shifting patients’ focus to the personal health costs of non-compliance may thus offer a potentially cost-effective and scalable approach to improving medication adherence.

Abstract
PURPOSE To assess which factors in the lives and disease of patients with glaucoma affect their adherence to topical glaucoma therapy and the quantitative significance of this effect. To assess qualitatively the most influential barriers to adherence from the perspective of the patient. DESIGN Multicenter, prospective, cross-sectional pilot study. PARTICIPANTS A total of 145 patients, attending outpatient metropolitan glaucoma clinics in Sydney, Australia, who were prescribed topical glaucoma medications. METHODS A structured interview-based questionnaire was conducted with 145 individuals using glaucoma eye drops that had been prescribed at least 2 weeks previously. The questionnaire involved 2 novel questions on adherence, 29 questions on factors identified or postulated in the literature as affecting adherence for quantitative analysis, and 1 open-response question on patient-identified causes of nonadherence for qualitative analysis. This questionnaire represents the broadest coverage of factors hypothesized to affect adherence in a single study in the glaucoma medication adherence literature to date. MAIN OUTCOME MEASURES Adherence rate, risk factors for poor adherence, and patient-identified barriers to adherence. RESULTS In response to the question "How many days have you missed a drop in the last 2 weeks," 69.7% of patients reported total adherence. Four factors were significantly related to an increased likelihood of reporting having missed drops in the last 2 weeks. These were difficulty applying drops (odds ratio [OR], 2.35; 95% confidence interval [CI], 1.02-5.44; P < 0.05), a past or current diagnosis of depression (OR, 3.61; 95% CI, 1.53-8.52; P < 0.01), patient self-rating of own memory ≤ 7 of 10 (OR, 3.15; 95% CI, 1.36-7.30; P < 0.01), and self-reported motivation score ≤ 6 of 10 (OR, 10.94; 95% CI, 3.00-39.81; P < 0.01). Patient understanding of glaucoma, ethnicity, and socioeconomic status were among the 25 factors found not to have a statistically significant correlation with adherence. CONCLUSIONS There is a significant proportion of patients taking their topical glaucoma medications less often than prescribed. Adherence to topical glaucoma therapies is negatively correlated to several factors: difficulty applying drops, a past or current diagnosis of depression, poor self-rating of own memory, and poor self-rating of own motivation. These may prove useful in designing interventions to improve adherence in these patients.

Automated, Noncontact Intraocular Pressure Home Monitoring after Implantation of a Novel Telemetric Intraocular Pressure Sensor in Patients with Glaucoma: A Feasibility Study. BIOMED RESEARCH INTERNATIONAL 2019; 2018:4024198. [PMID: 30627553 PMCID: PMC6304593 DOI: 10.1155/2018/4024198] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/03/2018] [Accepted: 11/21/2018] [Indexed: 11/30/2022]
Abstract
Purpose Reliable and regular assessment of intraocular pressure (IOP) is important for the monitoring of patients with glaucoma. The purpose of this study was to evaluate the feasibility of a novel system for the automated, noncontact measurement of IOP. Patients and Methods A first-generation telemetric IOP sensor was previously implanted in the ciliary sulcus of six patients with open-angle glaucoma during cataract surgery. Using this technology, automated noninvasive tonometry may be performed in a home setting. In the present study, a modified sleep mask and a modified eyepatch with incorporated coil antennae for measurements during nighttime and daytime, respectively, were tested on a single patient. Results In this feasibility study, the 24 h wear of the prototype measuring apparatus was well tolerated. Three sequences of 24 h IOP measurements with at least 200 IOP measurements per day were performed (Sequence 1: mean 19.6 ± 2.7 mmHg, range 13.4–28.7 mmHg; Sequence 2: mean 21.0 ± 3.0 mmHg, range 13.1–30.5 mmHg; Sequence 3: mean 19.9 ± 2.4 mmHg, range 12.6–27 mmHg). Conclusions For the first time, repeated and automated 24-hour measurements are possible using a prototype noncontact reading system after implantation of a novel telemetric IOP sensor in patients with glaucoma.

Abstract
PURPOSE Investigating patients' perceptions of their illness can provide important insights into the experience and management of the illness and associated treatment, and enhance understanding of variations in adherence to prescribed medication. The Common-Sense Model of Self-Regulation (CSM) provides a theoretical framework for the study of illness cognitions, health behavior, and adherence to health recommendations. The aim of this study was to use the CSM to investigate the experience of glaucoma and its treatment from the patients' perspective, and to apply these insights to classify and clarify issues related to nonadherence with treatment. PATIENTS AND METHODS A qualitative investigation using semi-structured interviews took place in two outpatient glaucoma clinics. Thirty-three patients with primary open-angle glaucoma using hypotensive eye drops participated in the study. Deductive content analysis was used to analyze the interview data. RESULTS Issues relating to nonadherence with hypotensive eye drops and patients' experience with their glaucoma and treatment were identified. Treatment schedule and patient factors were classified as common barriers to adherence. Further themes include experienced symptoms of glaucoma, illness coherence, and the emotional and practical consequences of the illness. CONCLUSION Findings provide important insights into the emotional and practical outcomes of glaucoma for patients, perceived symptoms of the illness, and insights into patient memory and cognition. These findings provide supporting evidence for the importance of conducting theoretically driven qualitative investigations of patients' experience with glaucoma and their treatment, and provide suggestions on key issues that need to be addressed in future multidimensional interventions aimed at improving adherence and patient quality of life.

Abstract
Medication nonadherence is a serious public health concern. Although there are promising interventions that improve medication adherence, most interventions are developed and tested in tightly controlled research environments that are dissimilar from the real-world settings where the majority of patients receive health care. Implementation science methods have the potential to facilitate and accelerate the translation shift from the trial world to the real world. We demonstrate their potential by reviewing published, high-quality medication adherence studies that could potentially be translated into clinical practice yet lack essential implementation science building blocks. We further illustrate this point by describing an adherence study that demonstrates how implementation science creates a junction between research and real-world settings. This article is a call to action for researchers, clinicians, policy makers, pharmaceutical companies, and others involved in the delivery of care to adopt the implementation science paradigm in the scale-up of adherence (research) programs.

Abstract
PURPOSE To evaluate the influence of prostaglandin (PG) analogues on the ciliary zonular fibers of the crystalline lens using scanning electron microscopy (SEM) of rabbit eyes, and to measure the matrix metalloproteinase (MMP) and tissue inhibitor of metalloproteinase (TIMP) levels of the aqueous humor and crystalline lens treated with topical PG analogues Methods: Fifty eyes from 25 New Zealand white rabbits were divided into five groups of five rabbits each. In the control group, balanced salt solution was administered via the topical route once a day to the eyes. The benzalkonium chloride (BAC) group was treated with 0.02% BAC, the Latanoprost group with 0.005% latanoprost, the Travoprost group with 0.004% Travoprost, and the Bimatoprost group with 0.03% Bimatoprost for 10 months. We examined the ciliary zonular fibers using SEM. We also measured the MMP and TIMP levels of the aqueous humor and crystalline lens. RESULTS SEM revealed some splitting of zonular fibers in eyes treated with topical PG analogues when compared with the control and BAC groups. The MMP-1 and TIMP-1 levels after treatment with the PG analogues did not differ significantly from the control and BAC groups (P > 0.05). There was no significant difference in MMP-1, MMP-3, TIMP-1, and MMP-1/TIMP-1 levels in the lens among all five groups. CONCLUSIONS PG analogues may induce zonular change in rabbits microscopically. There was no association between zonular changes and the levels of certain types of MMP or TIMP in the aqueous humor or crystalline lens after topical treatment with PG analogues.

Abstract
AIMS Patient-held records are becoming more commonly used in health care, particularly in chronic diseases like glaucoma. There is a lack of evidence to support their use, however. This study examines the change in knowledge scores within a group following the introduction of a newly designed glaucoma logbook. METHODS This analysis uses a test and retest method where patients undergoing treatment for glaucoma or ocular hypertension were assessed using a validated knowledge questionnaire. They were then given a personalized glaucoma logbook and their knowledge scores retested after 4 to 8 weeks. The change in knowledge score was examined using a Wilcoxon signed-rank test. RESULTS A total of 56 patients were recruited and 35 completed both questionnaires equating to a 62.5% retention rate. The analysis showed a significant increase in the knowledge score attained following introduction of the questionnaire (Z=-4.176, P<0.001). CONCLUSIONS In this format, the glaucoma logbook has a positive impact on patient knowledge. Further research will be necessary to show if this result is maintained in a larger sample group and to investigate whether this improvement in knowledge is associated with any improvement in long-term structural and functional outcomes.

Abstract
INTRODUCTION Few reports have investigated the status of adherence in Japan on a large scale. We aimed to investigate the status of adherence to topical glaucoma treatment and its associated factors. METHODS A nationwide survey was conducted as a prospective fashion. Participants in this survey were subjects with primary open-angle glaucoma, normal-tension glaucoma, or ocular hypertension or pseudoexfoliation glaucoma who had been prescribed anti-glaucoma ophthalmic eyedrops and whose ophthalmologist considered prescribing any fixed combination of ocular hypotensive eyedrops for the first time between 2011 and 2012. Subjects and their attending ophthalmologists independently completed a questionnaire by utilizing a fixed combination of ocular hypotensive eyedrops. RESULTS A total of 1358 ophthalmologists from 1071 medical institutions participated in this survey. We registered 4430 subjects (2049 males and 2381 females). In total, data from 3853 subjects (87.6%) were analyzed after inclusion of subjects based on inclusion and exclusion criteria. Good adherence was defined as not forgetting instillation during the past week. Rates of good adherence reported by subjects and ophthalmologists were 72.4 and 78.5%, respectively (P < 0.0001). The consistency of adherence evaluation between subjects and ophthalmologists was moderate [kappa score 0.5025 (95% confidence interval 0.4740-0.5309)]. Significant factors associated with adherence were size of clinic, age, gender, number of types of ocular hypotensive eyedrops, ease of instillation, preferred number of eyedrops, preferred frequency of instillation of eyedrops, and knowledge of glaucoma. CONCLUSION Adherence to ocular hypotensive eyedrops among Japanese subjects was relatively good. Concordance of adherence between subjects' reports and ophthalmologists' responses was moderate. Size of clinic, number of types of ocular hypotensive eyedrops, ease of instillation, preferred number of eyedrops, preferred frequency of instillation of eyedrops, and knowledge of glaucoma were associated with adherence among Japanese glaucoma subjects.

Abstract
PURPOSE We investigated patient adherence and factors related to a newly introduced prostaglandin analog and timolol fixed-combination eye drops (PGTFC). PATIENTS AND METHODS The Glaucoma Research on Adherence to fixed-Combination Eye drops in Japan (GRACE) study group performed a nationwide prospective questionnaire survey. Participants in this study were patients with glaucoma who were scheduled to receive any type of PGTFC for the first time. The participants answered a questionnaire on the day of PGTFC introduction and again at a return visit 4-6 weeks after PGTFC introduction. The physicians in charge were asked to complete a separate questionnaire on the day of PGTFC introduction. One of two leaflets was randomly delivered to each participant before the description of the PGTFC. One leaflet explained how to correctly instill the eye drops, and the other explained the clinical meaning of intraocular pressure reduction in addition to explaining how to correctly instill the eye drops. Nonadherence was defined as forgetting to instill the eye drops one or more times during the week before the return visit. RESULTS In total, 3,597 patients (age, 68.4±12.2 years) met the study protocol requirements. PGTFC introduction significantly reduced the number of antiglaucoma eye drops from 1.93±0.78 to 1.34±0.54 (P<0.0001) and significantly improved adherence (P<0.00001). Factors significantly associated with nonadherence at the return visit included a history of nonadherence as reported by either the patient or their physician before introduction, acceptable instillation times as reported by the patient, and burdensome eye drop instillation as reported by the patient. No significant difference was observed between the two leaflets in terms of their effects on adherence. CONCLUSION PGTFC significantly improved adherence and some of the factors that were significantly associated with adherence. REGISTRATION NUMBER UMIN000013696.

Abstract
OBJECTIVE The aim of this study was to evaluate patients' dissatisfaction with overall and specific aspects of a tertiary glaucoma service and to determine their independent factors, including intraocular pressure (IOP) and visual acuity (VA). METHODS Patients, aged ≥21 years, from a specialist glaucoma service in a tertiary eye hospital in Singapore for at least 6 months, were recruited for this cross-sectional study between March and June 2014. All consenting patients completed a 7-area glaucoma-specific satisfaction questionnaire and one item related to satisfaction with overall glaucoma care. We determined the top three areas of dissatisfaction and overall dissatisfaction with the glaucoma service. We also explored the independent factors associated with overall and specific areas of patients' dissatisfaction with their glaucoma care, including VA and IOP by using logistic regression models. RESULTS Of the 518 patients recruited, 438 (84.6%) patients completed the study. Patients' dissatisfaction with the overall glaucoma service was 7.5%. The three areas of glaucoma service with the highest dissatisfaction rates were as follows: 1) explanation of test results (24.8%); 2) explanation of glaucoma complications (23.7%); and 3) advice on managing glaucoma (23.5%). Patients who were dissatisfied with the overall service had a worse mean VA compared with satisfied patients (logarithm of the minimum angle of resolution =0.41±0.43 vs 0.27±0.49, p=0.005), whereas mean IOP remained well-controlled in both the groups (13.55±2.46 mmHg vs 14.82±2.86 mmHg, p=0.014). In adjusted models, factors associated with overall dissatisfaction with glaucoma care included a pre-university education and above (odds ratio [OR] =8.06, 95% CI =1.57-41.27) and lower IOP (OR =0.83, 95% CI =0.71-0.98). CONCLUSION Although less than one tenth of glaucoma patients were dissatisfied with the overall glaucoma service, one in four patients were dissatisfied with three specific aspects of care. A lower IOP, ironically, and education level were associated with overall dissatisfaction. Improving patients' understanding of glaucoma test results, glaucoma complications, and disease management may increase patient satisfaction levels.

Abstract
PURPOSE To assess whether provision of a personalized patient-held eye health summary (glaucoma personal record) improves patients' knowledge of glaucoma at 1-year follow-up. The National Institute for Clinical Excellence has recommended such an approach to ascertain if this may ultimately help slow disease progression. METHODS Recruited patients, newly diagnosed with glaucoma conditions, were randomly allocated to receive standard clinical care or an additional glaucoma personal record, detailing the current state of each individual's eye condition. Mann-Whitney U test was applied for comparison of knowledge scores between groups at 1-year follow-up, using a validated questionnaire. Multiple linear regression analysis was applied to detect any factors significantly associated with a difference in glaucoma knowledge. RESULTS A total of 122 patients were recruited; 57 controls and 44 intervention patients were tested for their glaucoma knowledge, equating to 83% retention rate. Out of a maximum available 100% converted score, the median scores were 58% and 53% for the control and intervention arm, respectively (p = 0.85). Regression analysis showed that age (p = 0.015) had a negative association and level of education (p = 0.002) had a positive association with glaucoma knowledge. CONCLUSIONS The glaucoma personal record does not impact on a patient's knowledge of glaucoma in either a positive or negative way. Other approaches to improve health literacy among glaucoma patients, particularly for patients who are elderly or have a limited educational background, must be considered to improve patients' awareness and knowledge of their own condition.

Abstract
BACKGROUND Poor medication adherence is a major public health problem in older adults often resulting in negative health outcomes. OBJECTIVE The objective of this review was to provide an updated summary of evidence from randomized controlled studies to determine whether interventions aimed at improving medication adherence also improve the health outcomes of older adults residing in community-based settings. METHODS Articles that assessed medication adherence interventions and related health outcomes in elderly individuals were identified through searches of MEDLINE (1970-June 2016), the Cochrane Database of Systematic Reviews (through to June 2016), and Google Scholar. Across the 12 included studies, interventions were grouped into three main categories: behavioral/educational (n = 3), pharmacist-led (n = 7), and reminder/simplification (n = 2). RESULTS Among the behavioral/educational intervention studies, two showed improvements in both adherence and related health outcomes, whereas one found no changes in adherence or health outcomes. Among the pharmacist-led studies, three showed improvements in both adherence and related health outcomes, while three reported no changes in adherence or health outcomes. One found an improvement in adherence but not health outcomes. Among the reminder/simplification studies, both studies reported improvements in adherence without a significant impact on related health outcomes. CONCLUSION This evidence-based review of medication adherence interventions in older adults revealed promising strategies in the larger context of a largely mixed body of literature. Future patient-centered and multidisciplinary interventions should be developed and tested using evidence-based principles to improve medication adherence and health outcomes in older adults.

Abstract
Glaucoma is a medical term describing a group of progressive optic neuropathies characterized by degeneration of retinal ganglion cells and retinal nerve fibre layer and resulting in changes in the optic nerve head. Glaucoma is a leading cause of irreversible vision loss worldwide. With the aging population it is expected that the prevalence of glaucoma will continue to increase. Despite recent advances in imaging and visual field testing techniques that allow establishment of earlier diagnosis and treatment initiation, significant numbers of glaucoma patients are undiagnosed and present late in the course of their disease. This can lead to irreversible vision loss, reduced quality of life, and a higher socioeconomic burden. Selection of therapeutic approaches for glaucoma should be based on careful ocular examination, patient medical history, presence of comorbidities, and awareness of concomitant systemic therapies. Therapy should also be individualized to patients' needs and preferences. Recent developments in this therapeutic field require revisiting treatment algorithms and integration of traditional and novel approaches in order to ensure optimal visual outcomes. This article provides an overview of recent developments and practice trends in the medical management of glaucoma in Canada. A discussion of the surgical management is beyond the scope of this paper.

Abstract
The treatment paradigm in glaucoma classically starts with exhausting all medical therapy prior to proceeding with laser or incisional surgery, although laser-first and surgery-first strategies have been explored in randomized clinical trials. Although glaucoma drops are proven to work well to lower intraocular pressure, slow the conversion from ocular hypertension, and slow the progression of disease in early open angle glaucoma, adherence to treatment is likely optimum in the randomized clinical trials that support these claims. In real-world scenarios, medical therapy often fails and practitioners are forced to proceed with more invasive treatment modalities to slow the progression of this blinding disease. This review aims to take an evidence-based approach to study the risk factors for poor adherence in glaucoma patients, to determine whether poor adherence is, in fact, associated with worse outcomes, and to seek potential strategies to improve adherence in these patients.

[PMID: 27257110 DOI: 10.1016/j.jfo.2016.02.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2015] [Revised: 01/17/2016] [Accepted: 02/29/2016] [Indexed: 11/21/2022]
Abstract
PURPOSE To evaluate the knowledge and compliance of patients with open-angle glaucoma in order to propose an approach by therapeutic education, validated for other chronic pathologies. METHODS A questionnaire-based interview of all patients in the waiting room of the glaucoma center is performed by the same health care professional. RESULTS Out of 200 patients, 73% know they will need to be treated throughout their lives and 95% are aware of the risk of blindness in the absence of appropriate treatment. However, 16% respond that they can be cured, and 54% believe that treatment can save their eyesight. Knowledge increases with the length of follow-up of patients at the glaucoma center beyond one year, but the progress is still insufficient in their confidence that treatment can save their eyesight (36% to 57%), and in the decrease in the number of patients who forget their treatment (56% to 30%). CONCLUSION Cognitive knowledge is insufficient to encourage the patient to comply with treatment. It is necessary to consider therapeutic patient education (TPE) techniques, such as described by WHO, in group and/or individual sessions, aimed at building the patient's confidence that treatment can delay the progression of the disease and blindness, strengthening his/her capacity to properly administer the eye drops, managing his/her treatment and coping with frequent side effects. Within this framework, our knowledge of the patients' representations of their glaucoma and its treatment must improve.

Abstract
PURPOSE To evaluate the current state of the research on educational interventions whose aim is to improve glaucoma medication adherence. METHODS A systematic review of Pubmed, Embase and CINAHL was conducted to identify research studies evaluating educational interventions to improve glaucoma medication adherence. Studies were included if the intervention was described, the outcomes assessed glaucoma medication adherence, and the focus of the research was on adults with glaucoma. The search was conducted on June 2, 2015. RESULTS Seventeen studies were identified that met the inclusion criteria. These included nine randomized controlled trials and eight observational studies. Eight of the studies demonstrated an impact on glaucoma medication adherence, though their outcome measures were too heterogeneous to estimate a pooled effect size.. CONCLUSION The interventions that successfully improved glaucoma medication adherence used an adequate dose of face-to-face counseling to overcome barriers to health behavior change alongside education about glaucoma.

Abstract
Glaucoma is a leading cause of visual morbidity throughout the world and is an age-related condition, the prevalence of which rises significantly with increasing age. Glaucoma, a condition affecting the optic nerve, has a variety of subtypes with multiple aetiological factors, the most important of which are intraocular pressure (IOP) and increasing age. Treatment by lowering of IOP is the only current method, for which there is evidence, by which the rate of progressive visual deterioration can be slowed or halted. Although there are surgical and laser treatments that are efficacious in lowering IOP, the most common manner in which patients with glaucoma control their IOP is with administration of daily topical ocular hypotensive drugs (eye drops). The variety of topical drugs utilised in the management of glaucoma all have the potential to have adverse effects and/or interactions with concomitant medications, many of which may be used for other age-related conditions. Adherence with appropriate medicines has a major effect on the outcome of medical conditions and this aspect applies to the management of glaucoma. There are certain specific issues that relate to the administration of topical agents, with respect to both adverse effects and adherence. Although many suspect poor adherence in elderly patients with glaucoma, relative to younger patients, adequate evidence for this is lacking. Furthermore, the manner by which adherence issues could be improved remains inadequately understood and poorly addressed. The aims of this article were to review, from a clinical perspective, the medical therapies currently used for glaucoma and discuss adherence issues with respect to the population of patients with glaucoma, who tend to be relatively elderly.

Abstract
BACKGROUND Sight loss from glaucoma can have a significant impact on functioning and performing everyday activities, but this varies between patients. The purpose of this study was to explore whether patients with glaucoma use different coping strategies in response to their vision loss. METHODS Audio-recorded semi-structured interviews were conducted with 16 patients (median age: 71 [interquartile range [IQR]: 68 to 77 years]; 50 % female) about their experiences of living with glaucoma. Patients had their glaucoma diagnosis for at least 5 years (range: 6 to 29 years) and had a range of disease severities (median best eye Mean Deviation was -9.1 dB [IQR: -12.9 to -4.1 dB]). A framework approach to analysis was taken whereby data was indexed using manual and computer-assisted methods, with codes applied to depict areas of functioning perceived to be impacted by glaucoma and coping behaviours used in response to these difficulties. RESULTS In order to maintain independence, some patients increased confidence by making practical changes such as adjusting lighting, using handrails and magnifying glasses, or actively changed aspects of their behaviour such as moving their head and eyes towards known areas of vision loss. Support from friends and family was often used, although some people worried about becoming a burden. Others imposed self-restrictions or gave up activities, thus compromising well-being and independence. Certain coping strategies were linked to time since diagnosis and location of vision loss. The type and quality of information received during clinical appointments, and the potential benefits of communication with other patients, emerged as other important themes. CONCLUSIONS Results from this qualitative study suggest that the adoption of certain coping behaviours and techniques may help some glaucomatous patients to adapt to their condition. An awareness of coping and adaptive strategies, in addition to the usual clinical tests, may provide a better insight into the impact of disease and help inform future educational and management strategies for glaucoma.

Patterns of Glaucoma Medication Adherence over Four Years of Follow-Up. Ophthalmology 2015; 122:2010-21.

Abstract
PURPOSE To assess longer-term patterns of glaucoma medication adherence and identify whether patterns established during the first year of medication use persist during 3 subsequent years of follow-up. DESIGN Retrospective, longitudinal cohort analysis. PARTICIPANTS Beneficiaries aged ≥40 years who were enrolled in a United States (US)-managed care plan for ≥7 years between 2001 and 2012 and newly diagnosed and treated for open-angle glaucoma. METHODS For each enrollee, we quantified medication adherence using the medication possession ratio. Group-based trajectory modeling (GBTM) was applied to identify patterns of adherence for 1 and 4 years of follow-up. The percent of beneficiaries who remained in the same trajectory group in the 1- and 4-year models was tabulated to evaluate group stability. Factors impacting adherence at 1 and 4 years were identified using regression analyses. MAIN OUTCOME MEASURES Patterns of glaucoma medication adherence. RESULTS Of the 1234 eligible beneficiaries, GBTM identified 5 distinct glaucoma medication adherence patterns in both the 1-year and 4-year follow-up periods. These groups were as follows: (1) never adherent after their index prescription fill (7.5% and 15.6% of persons in the 1- and 4-year models, respectively); (2) persistently very poor adherence (14.9% and 23.4% of persons in the 1- and 4-year models, respectively); (3) declining adherence (9.5% and 9.1% of persons in the 1- and 4-year models, respectively); (4) persistently moderate adherence (48.1% and 37.0% of persons in the 1- and 4-year models, respectively); and (5) persistently good adherence (20.0% and 15.0% of persons in the 1- and 4-year models, respectively). More than 90% of beneficiaries in the 4 groups with the worst and best adherence patterns (groups 1, 2, 3, 5) maintained their patterns from their first year throughout their 4 years of follow-up. Those with persistently moderate adherence (group 4), the largest group, were most likely to change groups from 1 to 4 years of follow-up. Persons with the best adherence over 4 years were more likely to be white, to be older, to earn >$60 000/year, and to have more eye care visits (P < 0.05 for all comparisons). Those with a higher initial copayment cost had lower adherence rates (β = -0.06/dollar, P = 0.03). CONCLUSIONS For most patients who were newly prescribed glaucoma medications, adherence patterns observed in the first year of treatment reflect adherence patterns over the subsequent 3 years. Investing resources in both identifying and helping patients with suboptimal adherence patterns over the first year may have a large impact on longer-term adherence.

The effectiveness of a 'glaucoma personal record' for newly diagnosed glaucoma patients: study protocol for a randomised controlled trial. Trials 2015; 16:337.

Abstract
Background Glaucoma involves progressive optic nerve fibre loss, subsequently leading to irreversible and disabling visual field defects. In Europe, the prevalence of glaucoma is approximately 2.2 % of all people aged over 40 years; this equates to 12 million people. Glaucoma patients require regular lifelong follow-up, contributing to a large financial and resource burden for the National Health Service (NHS) in the UK. This study aims to determine whether providing newly diagnosed glaucoma patients with a personalised client-held eye health summary (‘glaucoma personal record’), improves patients’ knowledge of their glaucoma condition. A potential long-term benefit could be improved self-management and henceforth a slower rate of deterioration. Methods/Design HOPE Glaucoma is a 3-year, prospective, parallel-group, pragmatic, single-centred, randomised controlled trial. An anticipated 122 adults, newly diagnosed with glaucoma (including ocular hypertension, suspected glaucoma and/or chronic open-angle glaucoma) will be recruited from a nurse-led ophthalmology outpatient clinic at a medium-sized NHS Trust. Participants will be randomly allocated to receive standard clinical care (control arm) or standard care plus a glaucoma personal record, detailing the current state of their condition (interventional arm). Participant assessments are designed to test whether provision of a glaucoma personal record 1) improves patient knowledge of glaucoma and 2) contributes to improvements in clinical outcomes, i.e. delay of visual field loss. The primary outcome measure is better client knowledge of glaucoma at the 9–12 month follow-up visit. Secondary outcome measures include the rate of visual field loss and patient-reported outcome measures on visual function (National Eye Institute VFQ – 25) measured at baseline, 9–12 months, 24 months and 36 months. Estimating a 20 % drop-out rate, the study will have 90 % power to detect a mean two-point difference in glaucoma knowledge score between groups at 5 % significance - based on two-sided Mann–Whitney U test. Discussion If a glaucoma personal record is found to significantly improve glaucoma patients’ knowledge of their condition, this intervention could potentially provide a low-cost, straightforward tool to educate and engage glaucoma patients. Subsequently, this could have the potential to increase patient self-management and therefore allow glaucoma patients to prolong their sight functionality for longer.

Abstract
Background: Understanding the magnitude of non-adherence in pre-marketing clinical trials and clinical practice is essential. However, accurately measuring non-adherence to medication is problematic, and the variety of adherence measures and/or calculation methods has led to highly variable results. Purpose: To compare commonly used methods for measuring adherence to eye drop therapy in order to assess which methods achieve the most complete datasets over an 8-month monitoring period, to quantify the magnitude of variance in adherence estimations and to review the different methods used to calculate or interpret adherence data. Methods: Adherence was measured electronically for 8 months by participants administering eye drops using a Travalert® dosing aid. The mean number of Travalert dosing aid recorded doses administered over the monitoring period was used to calculate a percentage adherence score. In addition, the value of graphically presenting Travalert dosing aid data to classify patterns of adherence behaviour was explored. The validated Morisky Measure of Adherence Scale and questions requesting participants to report the Frequency of Missed Doses were two measures of self-reported adherence calculated for each participant. Finally, medication possession ratio was calculated from expected repeat prescription orders compared with actual repeat prescription orders. Results: For the 208 recruited participants, self-reported adherence was the most reliable method of collecting complete datasets over the 8-month period; 16% of self-reported adherence data were missing compared with 45% of Travalert dosing aid data missing at 8 months. The mean adherence measured over the monitoring period by the Travalert dosing aid was 77%. When adherence measures were dichotomised into adherent and non-adherent groups, the Travalert dosing aid found 54% of participants were adherent, compared to 60% Morisky Measure of Adherence Scale and 57% Frequency of Missed Dose self-report measures. However, there was poor agreement between the Travalert dosing aid measured adherence and self-report measures. Medication possession ratio was not a reliable measure of persistence with medication. Graphical Travalert dosing aid data presentation provided additional information about participant behaviour by indicating that most non-adherence was due to participants taking drug holidays rather than missing occasional doses. Conclusion: The analysis provided evidence about the inconsistencies between different monitoring strategies and adherence measures. Furthermore, the analysis highlighted the difficulties in collecting complete data for studies investigating chronic, slowly progressive conditions that require long-term follow-up. Future adherence studies could use multiple methods for quantifying and classifying adherence in parallel, both to maximise precision of adherence estimates and to facilitate comparison between studies. However, the authors are cautious of the effect of using multiple adherence measures on participant behaviour and their potential reactivity effects is an area for future research.

Abstract
Purpose In response to recent calls for clearer specification of behavior change interventions, the purpose of this study was to apply a system of taxonomy for behavior change techniques (BCTs) to two educational interventions to improve adherence to glaucoma eye drops. Clarification of constituent BCTs will promote easy and reliable application of the interventions in clinical settings and research. Methods A published taxonomy of BCTs was used to code two interventions (group and individual) to increase adherence to eye drops. Intervention materials were coded by assigning a BCT label to each text unit. We noted the frequency with which each BCT occurred, compared the interventions in terms of the BCTs that were delivered, and identified whether the taxonomy was sufficient to describe the intervention components. Results The individual intervention consisted of 94 text units. Fifty-seven were identified as targeting behavior change and coded using 18 BCTs, many coded more than once. In the group intervention, 165 units of text were identified, and 125 were coded using 22 BCTs. The most frequently coded BCT was “provide information about behavior–health link” in the group intervention and “prompt barrier identification” in the individual intervention. The interventions included similar BCTs. All text units targeting behavior change were codable into BCTs. Conclusion The similarity of the two interventions may have implications for the cost-effectiveness of the interventions. The taxonomy was found sufficient to describe both interventions. This level of specification can be used to ensure that precisely the same intervention that has been pilot tested is reproducible in the clinical setting and in any further research.

Abstract
PURPOSE The goal of this study was to determine the adherence of glaucoma patients to their topical glaucoma medication. Furthermore, the relationships between the adherence behavior and the patients' demographic data, clinical characteristics, and their knowledge about glaucoma were evaluated. METHODS This was a prospective study of 123 patients with primary open-angle glaucoma who were given two standardized questionnaires. The first questionnaire at time point T1 comprised a knowledge assessment and the self-reported adherence measures Adherence to Refills and Medication Scale 2 (ARMS2), visual analogue scale for adherence (VAS-AD), and missed doses in the past 14 days. Two months later at time point T2, a second questionnaire reevaluated the adherence measures ARMS2, VAS-AD, and missed doses in the past 14 days. RESULTS There was a good correlation among all the three adherence measures at T1 and T2. The mean values of ARMS2 were in the lower range, with 3.38 at T1 and 2.8 at T2. The VAS-AD detected that 18.5% of patients always took their eye drops correctly, and 77.9% of patients reported not to have missed a single dose in the past 14 days. There was no significant correlation between the patients' demographic data or knowledge about glaucoma and the adherence measures ARMS2 or VAS-AD. Among the clinical characteristics, only single-eye blindness showed a significant correlation with VAS-AD. CONCLUSION In this study, no general relationships were found between medication adherence and the patients' demographic data, clinical characteristics, or knowledge about glaucoma. It may be assumed that more individualized strategies are required to optimize adherence behavior.

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.

Improving adherence to glaucoma medication: a randomised controlled trial of a patient-centred intervention (The Norwich Adherence Glaucoma Study). BMC Ophthalmol 2014; 14:32. [PMID: 24655814 PMCID: PMC3994324 DOI: 10.1186/1471-2415-14-32] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2013] [Accepted: 03/17/2014] [Indexed: 11/21/2022] Open
Abstract
Background Improving adherence to ocular hypertension (OH)/glaucoma therapy is highly likely to prevent or reduce progression of optic nerve damage. The present study used a behaviour change counselling intervention to determine whether education and support was beneficial and cost-effective in improving adherence with glaucoma therapy. Methods A randomised controlled trial with a 13-month recruitment and 8-month follow-up period was conducted. Patients with OH/glaucoma attending a glaucoma clinic and starting treatment with travoprost were approached. Participants were randomised into two groups and adherence was measured over 8 months, using an electronic monitoring device (Travalert® dosing aid, TDA). The control group received standard clinical care, and the intervention group received a novel glaucoma education and motivational support package using behaviour change counselling. Cost-effectiveness framework analysis was used to estimate any potential cost benefit of improving adherence. Results Two hundred and eight patients were recruited (102 intervention, 106 control). No significant difference in mean adherence over the monitoring period was identified with 77.2% (CI, 73.0, 81.4) for the control group and 74.8% (CI, 69.7, 79.9) for the intervention group (p = 0.47). Similarly, there was no significant difference in percentage intraocular pressure reduction; 27.6% (CI, 23.5, 31.7) for the control group and 25.3% (CI, 21.06, 29.54) for the intervention group (p = 0.45). Participants in the intervention group were more satisfied with information about glaucoma medication with a mean score of 14.47/17 (CI, 13.85, 15.0) compared with control group which was 8.51 (CI, 7.72, 9.30). The mean intervention cost per patient was GB£10.35 (<US$16) and not cost-effective. Conclusions Adherence with travoprost was high and not further increased by the intervention. Nevertheless, the study demonstrated that provision of information, tailored to the individual, was inexpensive and able to achieve high patient satisfaction with respect to information about glaucoma medication. Measurement of adherence remains problematic since awareness of study participation may cause a change in participant behaviour. Trial registration Current Controlled Trials, ISRCTN89683704.

Kashiwagi K, Tsukahara S. Impact of patient access to Internet health records on glaucoma medication: randomized controlled trial. J Med Internet Res 2014; 16:e15. [PMID: 24429379 PMCID: PMC3906702 DOI: 10.2196/jmir.2795] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2013] [Revised: 10/07/2013] [Accepted: 12/05/2013] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Glaucoma is one of the leading causes of blindness. Reduction of intraocular pressure is the only proven way to prevent progression of glaucomatous optic neuropathy. The majority of glaucoma patients need to use antiglaucoma ophthalmic solutions over the course of their life. Thus, good adherence and persistency of glaucoma treatment are important factors for better glaucoma care. OBJECTIVE The purpose of this study was to investigate the impact of an Internet-based glaucoma care support system on glaucoma medication use. METHODS Patients were randomly divided into two groups. The non-Internet access (NIA) group consisted of patients who had access to the Internet-based glaucoma care support system during the 4-year period only when they were examined by ophthalmologists. The Internet access (IA) group consisted of patients who had the same Internet-based glaucoma care support system access as the NIA group for the first 2 years following enrollment but who were also given free access to the glaucoma care support system for the remaining 2 years. Changes in glaucoma medication use were investigated. RESULTS In total, 81 patients in the IA group and 90 patients in the NIA group satisfied the study protocol. The number of antiglaucoma ophthalmic solutions used during the study period significantly increased in the NIA group (P<.03) but not in the IA group. The percentages of patients with unchanged, increased, and decreased antiglaucoma ophthalmic solution use during the study period were 61.1% (55/90), 17.8% (16/90), and 3.3% (3/90), respectively, in the NIA group, and 56.8% (46/81), 8.6% (7/81), and 13.6% (11/81), respectively, in the IA group (P<.001). Internet access significantly shifted from an increasing intraocular pressure trend to a decreasing trend in the IA group (P=.002) among the patients who did not have any medication changes. CONCLUSIONS Allowing patients to browse their medical data may reduce the use and improve the effectiveness of glaucoma medication.

Understanding patients' adherence-related beliefs about medicines prescribed for long-term conditions: a meta-analytic review of the Necessity-Concerns Framework. PLoS One 2013; 8:e80633. [PMID: 24312488 PMCID: PMC3846635 DOI: 10.1371/journal.pone.0080633] [Citation(s) in RCA: 759] [Impact Index Per Article: 63.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2013] [Accepted: 10/04/2013] [Indexed: 01/19/2023] Open
Abstract
BACKGROUND Patients' beliefs about treatment influence treatment engagement and adherence. The Necessity-Concerns Framework postulates that adherence is influenced by implicit judgements of personal need for the treatment (necessity beliefs) and concerns about the potential adverse consequences of taking it. OBJECTIVE To assess the utility of the NCF in explaining nonadherence to prescribed medicines. DATA SOURCES We searched EMBASE, Medline, PsycInfo, CDSR/DARE/CCT and CINAHL from January 1999 to April 2013 and handsearched reference sections from relevant articles. STUDY ELIGIBILITY CRITERIA Studies using the Beliefs about Medicines Questionnaire (BMQ) to examine perceptions of personal necessity for medication and concerns about potential adverse effects, in relation to a measure of adherence to medication. PARTICIPANTS Patients with long-term conditions. STUDY APPRAISAL AND SYNTHESIS METHODS Systematic review and meta-analysis of methodological quality was assessed by two independent reviewers. We pooled odds ratios for adherence using random effects models. RESULTS We identified 3777 studies, of which 94 (N = 25,072) fulfilled the inclusion criteria. Across studies, higher adherence was associated with stronger perceptions of necessity of treatment, OR = 1.742, 95% CI [1.569, 1.934], p<0.0001, and fewer Concerns about treatment, OR = 0.504, 95% CI: [0.450, 0.564], p<0.0001. These relationships remained significant when data were stratified by study size, the country in which the research was conducted and the type of adherence measure used. LIMITATIONS Few prospective longitudinal studies using objective adherence measures were identified. CONCLUSIONS The Necessity-Concerns Framework is a useful conceptual model for understanding patients' perspectives on prescribed medicines. Taking account of patients' necessity beliefs and concerns could enhance the quality of prescribing by helping clinicians to engage patients in treatment decisions and support optimal adherence to appropriate prescriptions.
