Duong JQ, Bloomquist RF, Feldman SR. How can physicians improve medication adherence and outcomes in dermatological conditions? Expert Rev Pharmacoecon Outcomes Res 2024:1-8. [PMID: 38914008 DOI: 10.1080/14737167.2024.2370911] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Accepted: 06/18/2024] [Indexed: 06/26/2024]
Abstract
INTRODUCTION Medication non-adherence is a major contributor to suboptimal disease treatment across medical specialties and is a particular hurdle with topicals. While adherence is a patient behavior affected by many socioeconomic and health system factors, physicians can play an important role in encouraging good adherence. AREAS COVERED We discuss methods for measuring adherence, including ethics of such research, provide select examples of dermatology-specific adherence studies, and conclude with physician-focused practices to improve patients' adherence. Articles were selected from a PubMed search spanning 2003 to 10 December 2023, using the following terms: 'dermatology,' 'medication,' 'treatment,' 'adherence,' 'compliance,' and 'intervention.' EXPERT OPINION Poor adherence to treatment is a major cause of poor treatment outcomes. As the goal of medical care is to achieve successful treatment outcomes, encouraging good adherence may be as much a foundation of care as making the right diagnosis and prescribing the right treatment. Taking a doctor-centric perspective on reasons for non-adherence may be more productive than simply finding fault with the patient. Establishing trust and accountability is a foundation for good adherence; after establishing the provider-patient relationship, physicians can improve adherence by incorporating behavioral and counseling strategies, communicating through technology, and advocating for distribution of validated educational information.

Effectiveness of a Multifaceted Mobile Health Intervention (Multi-Aid-Package) in Medication Adherence and Treatment Outcomes Among Patients With Hypertension in a Low- to Middle-Income Country: Randomized Controlled Trial. JMIR Mhealth Uhealth 2024; 12:e50248. [PMID: 38896837 DOI: 10.2196/50248] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2023] [Revised: 01/31/2024] [Accepted: 04/30/2024] [Indexed: 06/21/2024] Open
Abstract
BACKGROUND The high prevalence of uncontrolled hypertension in Pakistan is predominantly attributed to poor medication adherence. As more than 137 million people in Pakistan use cell phones, a suitable mobile health (mHealth) intervention can be an effective tool to overcome poor medication adherence. OBJECTIVE We sought to determine whether a novel mHealth intervention is useful in enhancing antihypertensive therapy adherence and treatment outcomes among patients with hypertension in a low- to middle-income country. METHODS A 6-month parallel, single-blinded, superiority randomized controlled trial recruited 439 patients with hypertension with poor adherence to antihypertensive therapy and access to smartphones. An innovative, multifaceted mHealth intervention (Multi-Aid-Package), based on the Health Belief Model and containing reminders (written, audio, visual), infographics, video clips, educational content, and 24/7 individual support, was developed for the intervention group; the control group received standard care. The primary outcome was self-reported medication adherence measured using the Self-Efficacy for Appropriate Medication Adherence Scale (SEAMS) and pill counting; the secondary outcome was systolic blood pressure (SBP) change. Both outcomes were evaluated at baseline and 6 months. Technology acceptance feedback was also assessed at the end of the study. A generalized estimating equation was used to control the covariates associated with the probability of affecting adherence to antihypertensive medication. RESULTS Of 439 participants, 423 (96.4%) completed the study. At 6 months post intervention, the median SEAMS score was statistically significantly higher in the intervention group compared to the controls (median 32, IQR 11 vs median 21, IQR 6; U=10,490, P<.001). Within the intervention group, there was an increase in the median SEAMS score by 12.5 points between baseline and 6 months (median 19.5, IQR 5 vs median 32, IQR 11; P<.001). Results of the pill-counting method showed an increase in adherent patients in the intervention group compared to the controls (83/220, 37.2% vs 2/219, 0.9%; P<.001), as well as within the intervention group (difference of n=83, 37.2% of patients, baseline vs 6 months; P<.001). There was a statistically significant difference in the SBP of 7 mmHg between the intervention and control groups (P<.001) at 6 months, a 4 mmHg reduction (P<.001) within the intervention group, and a 3 mmHg increase (P=.314) within the controls. Overall, the number of patients with uncontrolled hypertension decreased by 46 in the intervention group (baseline vs 6 months), but the control group remained unchanged. The variables groups (adjusted odds ratio [AOR] 1.714, 95% CI 2.387-3.825), time (AOR 1.837, 95% CI 1.625-2.754), and age (AOR 1.618, 95% CI 0.225-1.699) significantly contributed (P<.001) to medication adherence. Multi-Aid-Package received a 94.8% acceptability score. CONCLUSIONS The novel Multi-Aid-Package is an effective mHealth intervention for enhancing medication adherence and treatment outcomes among patients with hypertension in a low- to middle-income country.

Behav Sci (Basel) 2024; 14:489.

Abstract
This article presents a comprehensive and multistage approach to the development of the user experience (UX) for an mHealth application targeting older adult patients with chronic diseases, specifically chronic heart failure and chronic obstructive pulmonary disease. The study adopts a mixed methods approach, incorporating both quantitative and qualitative components. The underlying hypothesis posits that baseline medicine adherence knowledge (measured by the MARS questionnaire), beliefs about medicines (measured by the BMQ questionnaire), and level of user experience (measured by the SUS and UEQ questionnaires) act as predictors of adherence change after a period of usage of the mHealth application. However, contrary to our expectations, the results did not demonstrate the anticipated relationship between the variables examined. Nevertheless, the qualitative component of the research revealed that patients, in general, expressed satisfaction with the application. It is important to note that the pilot testing phase revealed a notable prevalence of technical issues, which may have influenced participants' perception of the overall UX. These findings contribute to the understanding of UX development in the context of mHealth applications for older adults with chronic diseases and emphasise the importance of addressing technical challenges to enhance user satisfaction and engagement.

Abstract
OBJECTIVES This quantitative survey sought to understand, among men who have sex with men (MSM) with potentially problematic substance use, the attitudes towards participation in research involving digital pill systems (DPS) for HIV pre-exposure prophylaxis (PrEP) adherence measurement, and the barriers and facilitators to research participation. DESIGN One-time, cross-sectional, online sampling-based survey. SETTING US social networking app predominantly focused on MSM. PARTICIPANTS MSM without HIV who reported current use of oral PrEP, potentially problematic substance use and sexual activity in the past 3 months. A total of 157 participants were eligible, passed validity checks and enrolled. OUTCOME MEASURES Perceptions of DPS usefulness, accuracy and usability (System Usability Scale (SUS)); willingness and motivations to participate in DPS research; preferences for access to and feedback on DPS adherence data; data sharing considerations; and medical mistrust (Group-Based Medical Mistrust Scale (GBMMS)). RESULTS Most of the sample (N=157) was white (n=119, 75.8%), gay (n=124, 79.0%) and cisgender (n=150, 95.5%). The median age was 33 years (IQR: 14). The mean GBMMS score was 13.5 (SD=5.2), and the median SUS score was 70 (IQR: 27.5). In the past 3 months, 36.3% (n=57) reported frequent use of substances before or during sex, and 62.4% (n=98) engaged in condomless sex. While most were adherent to PrEP, approximately 34.4% (n=54) expressed significant worry about daily adherence. Participants wished to monitor their PrEP adherence daily (n=66, 42.0%) and 52% (n=82) were very willing to participate in DPS-based research. The majority were minimally concerned about sharing DPS-detected adherence data with research teams (n=126, 80.3%), and were extremely willing to share these data with healthcare providers (n=109, 69.4%). CONCLUSIONS In this sample, MSM without HIV who use substances reported willingness to use DPS to measure PrEP adherence in a research context, and identified benefits to accessing real-time, DPS-detected adherence data.

Factors associated with study protocol adherence and bio banking participation in reproductive medicine clinical trials and their relationship to live birth. Hum Reprod 2021; 35:2819-2831.

Abstract
STUDY QUESTION What demographic and baseline characteristics are predictive of adherence to reproductive medicine clinical trial protocols, live birth or participation in genetic studies? SUMMARY ANSWER Race, BMI and lower income are associated with likelihood of non-adherent to reproductive medicine clinical trial protocols, while race influences collection of biological samples and non-adherent to study protocols is associated with lower probability of live birth. WHAT IS KNOWN ALREADY Although aspects of adherence to study protocol have previously been evaluated as individual factors in infertile women, the factors that affect overall non-adherent to study protocol have not been previously evaluated. STUDY DESIGN, SIZE, DURATION A secondary data analysis of 1650 participants from two prospective multicenter, double-blind controlled studies was carried out: Pregnancy in Polycystic Ovary Syndrome II (PPCOS II) and Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation (AMIGOS). PARTICIPANTS/MATERIALS, SETTING, METHODS The participants were women aged 18-40 years old with either polycystic ovary syndrome (PCOS) with ovulatory dysfunction in combination with either hyperandrogenemia and/or polycystic ovarian morphology (PPCOS II), or regular ovulatory cycles with unexplained infertility (AMIGOS). The study was carried out in 14 clinical sites in the USA. Non-adherence to clinical trial protocol was chosen as the primary outcome for this analysis. To evaluate whether demographic and baseline characteristics were predictive of adherence to study protocols, live birth or participation in blood sampling for DNA and repository, and pregnancy registry, these putative factors were compared between the outcome measures. Logistic regression was used to establish a prediction model using the putative predictors introduced above. MAIN RESULTS AND THE ROLE OF CHANCE Women who self-identified as African American or Asian and those with higher BMI and lower household income were less likely to adhere to protocol. Non-adherence to the study protocol was associated with a lower probability of live birth (odds ratio: 0.180, 95% CI: 0.120, 0.272, P < 0.001). African Americans or Asians were less likely to participate in optional study DNA collection compared to Whites. Participants who were African American or with high annual income or from the Southwest sites or had PCOS were less likely to participate in the blood repository studies. LIMITATIONS, REASONS FOR CAUTION Race and ethnicity were self-reported and such self-classification to strict race and ethnicity may not always be representative of a whole racial or ethnic group. This study included two US multicenter trials and therefore the findings may not be extrapolated to international trials. WIDER IMPLICATIONS OF THE FINDINGS Identification of populations with low participation is an important initial step, as further investigation can develop specific measures to improve adherence to study protocols and participation in biospecimen banking and thereby extend the representativeness of reproductive medicine clinical trial findings. STUDY FUNDING/COMPETING INTEREST(S) Supported by NIH Eunice Kennedy Shriver NICHD Grants: U10 HD39005, U10 HD38992, U10 HD27049, U10 HD38998, U10 HD055942, HD055944, U10 HD055936, U10HD055925, PPCOSII: U10 HD27049, U10 HD38992, U10 HD055925, U10 HD39005, U10 HD38998, U10 HD055936, U10 HD055942, U10 HD055944; Clinical Reproductive Endocrine Scientist Training Program (CREST): R25HD075737.

Abstract
BACKGROUND Poor adherence to antiepileptic medication is associated with increased mortality, morbidity and healthcare costs. In this review, we focus on interventions designed and tested in randomised controlled trials (RCTs) and quasi-RCTs to assist people with adherence to antiepileptic medication. This is an update of a Cochrane review first published in 2011, and last updated in 2017. OBJECTIVES To determine the effectiveness of interventions aimed at improving adherence to antiepileptic medication in adults and children with epilepsy. SEARCH METHODS For the latest update, we searched the following databases on 18 February 2020: Cochrane Register of Studies (CRS Web), MEDLINE, CINAHL Plus and PsycINFO. CRS Web includes RCTs or quasi-RCTs from PubMed, Embase, ClinicalTrials.gov, the World Health Organization International Clinical Trials Registry Platform (ICTRP), CENTRAL, and the Specialized Registers of Cochrane Review Groups including Epilepsy. We also searched the reference lists of relevant articles. SELECTION CRITERIA RCTs and quasi-RCTs of adherence-enhancing interventions aimed at people with a clinical diagnosis of epilepsy (as defined in individual studies), of any age and treated with antiepileptic drugs in a primary care, outpatient or other community setting. DATA COLLECTION AND ANALYSIS All review authors independently assessed lists of potentially relevant citations and abstracts. At least two review authors independently extracted data and performed a quality assessment of each study according to the Cochrane tool for assessing risk of bias. We graded the level of evidence for each outcome according to GRADE. The studies differed widely according to the type of intervention and measures of adherence; therefore combining data was not appropriate. MAIN RESULTS We included 20 studies reporting data on 2832 participants. Thirteen studies targeted adults with epilepsy, one study included participants of all ages, one study included participants older than two years, one recruited pediatric patients aged between 1 month to 15 years, one study targeted caregivers of children with epilepsy, one targeted adolescents and caregivers, and two studies targeted families of children with epilepsy. We identified three ongoing studies. Follow-up time was generally short in most studies, ranging from 1 to 12 months. The studies examined three main types of interventions: educational interventions, behavioural interventions and mixed interventions. All but three studies compared treatment with usual care or 'no intervention'. Due to heterogeneity between studies in terms of interventions, methods used to measure adherence and the way the studies were reported, we did not pool the results and these findings were inappropriate to be included in a meta-analysis. Education and counselling of participants with epilepsy had mixed success (moderate-certainty evidence). Behavioural interventions such as the use of intensive reminders provided more favourable effects on adherence (moderate-certainty evidence). The effect on adherence to antiepileptic drugs described by studies of mixed interventions showed improved adherence in the intervention groups compared to the control groups (high-certainty evidence). Eleven studies described seizure frequency or seizure severity or both, with four of them, reporting improved adherence and decreased seizure frequency in the intervention groups (moderate-certainty evidence). Findings related to self-efficacy and quality of life were mixed, with no clear pattern across types of intervention. AUTHORS' CONCLUSIONS Behavioural interventions such as intensive reminders and the use of mixed interventions demonstrate some positive results, however, we need more reliable evidence on their efficacy, derived from carefully-designed RCTs before we can draw a firm conclusion. None of the newly included studies have provided additional information that would lead to significant changes in our conclusions.

Abstract
Non-adherence to medication is a key worldwide issue and can lead to adverse patient outcomes and increased health system costs. Would a process facilitating notification of non-adherence infringe upon the autonomy of individuals or breach expectations of privacy? In contrast, patients who are not taking their medication could unknowingly be putting themselves at risk and all the while prescribers are unaware and without the opportunity to intervene. With the advent of electronic methods of medication adherence monitoring, this ethical dilemma now involves a new layer of complexity. We present two scenarios encountered in clinical practice that reflect issues occurring regularly in the Canadian healthcare system.

Abstract
BACKGROUND An Asthma Adherence Pathway (AAP) application, which is an Internet application that combines patient and clinician education strategies to promote adherence to asthma therapy, has been developed. OBJECTIVE The primary objective of this pilot study was to evaluate the effectiveness of the AAP application with electronic adherence monitors on asthma control. Secondary objectives evaluated the effect of AAP and monitors on medication adherence, asthma symptoms, quality of life, psychosocial factors, and barriers to treatment. METHODS Adult patients with asthma were randomly assigned either to intervention (n = 19) or control (n = 20) groups in this 3-month prospective study, and they completed the Asthma Control Questionnaire (ACQ). Intervention patients completed the AAP software and were given barrier-specific motivational interviewing adherence strategies and a SmartTrack device to monitor mometasone furoate/formoterol (MF/F) use. Clinicians in the interventional group received adherence management training. Interventional patients were given feedback regarding adherence findings at each visit. Treatment adherence was determined by the mean of 4 measures of doses taken over 3 months. Control patients were not monitored for MF/F adherence. RESULTS The mean MF/F adherence in the intervention group was 81%. The intervention and control groups did not differ on the mean baseline ACQ. Thirteen intervention patients achieved the minimal important difference (defined as an improvement ≥0.5 units on the ACQ) compared with 6 control patients (P = .016). The intervention group showed greater improvement in the ACQ (0.75) than the control group (0.19) representing a moderate-to-large effect size of d = 0.638. CONCLUSIONS The AAP was effective in promoting adherence and helped to improve asthma control. These findings provide preliminary validation of the AAP model.

Abstract
Many new technologies monitor patients' and study participants' medical adherence. Some have cautioned that these devices transgress personal autonomy and ethics. But do they? This qualitative study explored how Ugandan study participants perceive the effect of electronic monitoring of their adherence to antiretroviral therapy (ART) on their freedoms to be non-adherent and pursue other activities that monitoring may inadvertently expose. Between August 2014 and June 2015, we interviewed 60 Ugandans living with HIV and enrolled in the Uganda AIDS Rural Treatment Outcomes (UARTO) study, a longitudinal, observational study involving electronic adherence monitors (EAMs) to assess ART adherence. We also interviewed 6 UARTO research assistants. Both direct and indirect content analysis were used to interpret interview transcripts. We found that monitoring created a sense of pressure to adhere to ART, which some participants described as "forcing" them to adhere. However, even participants who felt that monitoring forced them to take medications perceived using the EAM as conducive to their fundamental goal of high ART adherence. Overall, even if monitoring may have limited participants' effective freedom to be non-adherent, participants welcomed any such effect. No participant rejected the EAM on the grounds that it would limit that effective freedom. Reports that monitoring altered behaviors unrelated to pill-taking were rare. Researchers should continue to be vigilant about the ways in which behavioral health monitoring affects autonomy, but should also recognize that even autonomy-limiting monitoring strategies may enable participants to achieve their own goals.

Abstract
La non-observance des médicaments est un enjeu mondial primordial qui peut être responsable de résultats cliniques indésirables chez les patients et accroître les coûts pour le système de santé. Un processus facilitant la transmission d'avis de non-observance violerait-il l'autonomie individuelle ou les attentes en matière de confidentialité? En revanche, les patients qui ne prennent pas leurs médicaments se rendent peut-être à risque sans le savoir et sans que les prescripteurs en soient informés et puissent intervenir. Avec l'avènement des méthodes électroniques de surveillance de l'observance des médicaments, un nouveau niveau de complexité s'ajoute à ce dilemme éthique. Les auteurs présentent deux scénarios observés en clinique, qui reflètent des situations courantes au sein du système de santé canadien.

Abstract
BACKGROUND To investigate the performance and patient acceptability of an inhaler electronic monitoring device in a real-world childhood asthma population. METHODS Children 6 to 15 years presenting with asthma to the hospital emergency department and prescribed inhaled corticosteroids were included. Participants were randomized to receive a device with reminder features enabled or disabled for use with their preventer. Device quality control tests were conducted. Questionnaires on device acceptability, utility and ergonomics were completed at six months. RESULTS A total of 1306 quality control tests were conducted; 84% passed pre-issue and 87% return testing. The most common failure reason was actuation under-recording. Acceptability scores were high, with higher scores in the reminder than non-reminder group (median, 5th-95th percentile: 4.1, 3.1-5.0 versus 3.7, 2.3-4.8; p < 0.001). Most (>90%) rated the device easy to use. Feedback was positive across five themes: device acceptability, ringtone acceptability, suggestions for improvement, effect on medication use, and effect on asthma control. CONCLUSIONS This study investigates electronic monitoring device performance and acceptability in children using quantitative and qualitative measures. Results indicate satisfactory reliability, although failure rates of 13-16% indicate the importance of quality control. Favorable acceptability ratings support the use of these devices in children.

Abstract
BACKGROUND Poor adherence to antiepileptic medication is associated with increased mortality, morbidity and healthcare costs. In this review, we focus on interventions designed and tested in randomised controlled trials and quasi-randomised controlled trials to assist people with adherence to antiepileptic medication. This is an updated version of the original Cochrane review published in the Cochrane Library, Issue 1, 2010. OBJECTIVES To determine the effectiveness of interventions aimed at improving adherence to antiepileptic medication in adults and children with epilepsy. SEARCH METHODS For the latest update, on 4 February 2016 we searched the Cochrane Epilepsy Group Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL) via the Cochrane Register of Studies Online (CRSO), MEDLINE (Ovid 1946 to 4 February 2016), CINAHL Plus (EBSCOhost 1937 to 4 February 2016), PsycINFO (EBSCOhost 1887 to 4 February 2016), ClinicalTrials.gov, and the WHO International Clinical Trials Registry Platform. We also searched the reference lists of relevant articles. SELECTION CRITERIA Randomised and quasi-randomised controlled trials of adherence-enhancing interventions aimed at people with a clinical diagnosis of epilepsy (as defined in individual studies), of any age and treated with antiepileptic drugs in a primary care, outpatient or other community setting. DATA COLLECTION AND ANALYSIS All review authors independently assessed lists of potentially relevant citations and abstracts. At least two review authors independently extracted data and performed quality assessment of each study according to the Cochrane tool for assessing risk of bias. We graded the level of evidence for each outcome according to the GRADE working group scale.The studies differed widely according to the type of intervention and measures of adherence; therefore combining data was not appropriate. MAIN RESULTS We included 12 studies reporting data on 1642 participants (intervention = 833, control = 809). Eight studies targeted adults with epilepsy, one study included participants of all ages, one study included participants older than two years, one study targeted caregivers of children with epilepsy, and one study targeted families of children with epilepsy. We identified six ongoing trials. Follow-up time was generally short in most trials, ranging from one to 12 months. The trials examined three main types of interventions: educational interventions, behavioural interventions and mixed interventions. All studies compared treatment versus usual care or 'no intervention', except for two studies. Due to heterogeneity between studies in terms of interventions, methods used to measure adherence and the way the studies were reported, we did not pool the results and these findings were inappropriate to be included in a meta-analysis. Education and counselling of participants with epilepsy resulted in mixed success (moderate-quality evidence). Behavioural interventions such as use of intensive reminders provided more favourable effects on adherence (moderate-quality evidence). The effect on adherence to antiepileptic drugs described by studies of mixed interventions showed improved adherence in the intervention groups compared to the control groups (high-quality evidence). AUTHORS' CONCLUSIONS Behavioural interventions such as intensive reminders and the use of mixed interventions demonstrate some positive results; however, we need more reliable evidence on their efficacy, derived from carefully-designed randomised controlled trials before we can draw a firm conclusion. Since the last version of this review, none of the new relevant studies have provided additional information that would lead to significant changes in our conclusions. This current update includes 12 studies, of which six came from the latest searches.

Abstract
Adherence to preventive asthma treatment is poor, particularly in children, yet the factors associated with adherence in this age group are not well understood. Adherence was monitored electronically over 6 months in school-aged children who attended a regional emergency department in New Zealand for an asthma exacerbation and were prescribed twice-daily inhaled corticosteroids. Participants completed questionnaires including assessment of family demographics, asthma responsibility and learning style. Multivariable analysis of factors associated with adherence was conducted. 101 children (mean (range) age 8.9 (6–15) years, 51% male) participated. Median (interquartile range) preventer adherence was 30% (17–48%) of prescribed. Four explanatory factors were identified: female sex (+12% adherence), Asian ethnicity (+19% adherence), living in a smaller household (−3.0% adherence per person in the household), and younger age at diagnosis (+2.7% for every younger year of diagnosis) (all p<0.02). In school-aged children attending the emergency department for asthma, males and non-Asian ethnic groups were at high risk for poor inhaled corticosteroid adherence and may benefit most from intervention. Four factors explained a small proportion of adherence behaviour indicating the difficulty in identifying adherence barriers. Further research is recommended in other similar populations. Girls, children of Asian ethnicity, small household size and younger diagnosis age have better adherence to asthmahttp://ow.ly/Z1y6Q

Abstract
Electronic adherence monitors (EAMs) record and report an array of health behaviors, ranging from taking daily medications to wearing medical devices. EAMs are utilized in research worldwide and are being investigated for clinical use. However, there is also growing popular concern about the extent to which electronic devices may be used to monitor individuals, including allegations in the media that EAMs represent a move towards "Big Brother" in medicine. Here, we highlight the unique benefits as well as the potential ethical challenges that electronic adherence monitoring generates. These challenges surround autonomy, privacy and confidentiality, trust, and ancillary care obligations. We describe key questions within each of these domains that warrant further investigation, and present potential solutions to many of the concerns raised.

Abstract
Poor adherence to treatment is a common cause of medical treatment failure. Studying adherence is complicated by the potential for the study environment to impact adherence behavior. Studies performed without informing patients about adherence monitoring must balance the risks of deception against the potential benefits of the knowledge to be gained. Ethically monitoring a patient's adherence to a treatment plan without full disclosure of the monitoring plan requires protecting the patient's rights and upholding the fiduciary obligations of the investigator. Adherence monitoring can utilize different levels of deception varying from stealth monitoring, debriefing after the study while informing the subject that some information had been withheld in regard to the use of adherence monitoring (withholding), informed consent that discloses some form of adherence monitoring is being used and will be disclosed at the end of the study (authorized deception), and full disclosure. Different approaches offer different benefits and potential pitfalls. The approach used must balance the risk of nondisclosure against the potential for confounding the adherence monitoring data and the potential benefits that adherence monitoring data will have for the research subjects and/or other populations. This commentary aims to define various methods of adherence monitoring and to provide a discussion of the ethical considerations that accompany the use of each method and adherence monitoring in general as it is used in clinical research.

Abstract
BACKGROUND Cystic Fibrosis (CF) management requires complex treatment regimens but adherence to treatment is poor and has negative health implications. There are various methods of measuring adherence, but little is known regarding the extent of adherence measurement in CF centres throughout the UK and Ireland. OBJECTIVE To determine the adherence monitoring practices in CF centres throughout the UK and Ireland, and to establish CF pharmacists' views on these practices. SETTING UK and Ireland Cystic Fibrosis Pharmacists' Group's annual meeting (2014). METHODS A questionnaire was designed, piloted and distributed to pharmacists attending the UK and Ireland Cystic Fibrosis Pharmacists' Group's annual meeting (2014). The main outcome measures were the methods of inhaled/nebulised antibiotic supply and the methods used to measure treatment adherence in CF centres. The questionnaire also ascertained the demographic information of participating pharmacists. Closed question responses were analysed using descriptive statistics. Open questions were analysed using content analysis. RESULTS Twenty-one respondents (84 % response) were included in the analysis and were mostly from English centres (66.7 %). Detailed records of patients receiving their inhaled/nebulised antibiotics were lacking. Adherence was most commonly described to be measured at 'every clinic visit' (28.6 %) and 'occasionally' (28.6 %). Patient self-reported adherence was the most commonly used method of measuring adherence in practice (90.5 %). The availability of electronic adherence monitoring in CF centres did not guarantee its use. Pharmacists attributed an equal professional responsibility for adherence monitoring in CF to Consultants, Nurses and Pharmacists. Seventy-six percent of pharmacists felt that the current adherence monitoring practices within their own unit were inadequate and associated with the absence of sufficient specialist CF pharmacist involvement. Many suggested that greater specialist pharmacist involvement could facilitate improved adherence monitoring. CONCLUSION Current adherence knowledge is largely based on self-report. Further work is required to establish the most appropriate method of adherence monitoring in CF centres, to improve the recording of adherence and to understand the impact of increased specialist pharmacist involvement on that adherence.

Abstract
Medication nonadherence is a vexing problem in health care necessitating patients and health professionals' efforts to prevent, minimize, or reverse it. Research participants' inconsistent medication taking obscures treatment efficacy and adds costs to biomedical research. Electronic monitoring devices (EMDs), like the Medication Event Monitoring System (MEMS), have grown in sophistication, providing precise, timely insights into individuals' medication-taking patterns across clinical populations. This article reports on the desirability and feasibility study of using a wireless EMD in clinical research to promote adherence to clinical regimens and research protocols. Nonadherence in transplant patients has been linked to late acute rejection and graft loss. High levels of adherence (97.7 %) were documented for six renal transplant recipients for a mean of 6 months (M = 196.1 ± 71.2 days) who indicated acceptance of the technology. MEMS data confirmed the feasibility of using wireless EMDs to monitor medication use. Monitoring provides greater assurance that research studies reflect the biological impact of medications and provide a basis for targeting adherence enhancement efforts within research investigations.

Abstract
BACKGROUND Suboptimum adherence to preventive asthma treatment is associated with substantial morbidity and mortality, yet adherence often remains poor. We aimed to investigate whether use of an inhaler with audiovisual reminders leads to improved adherence and asthma outcomes in school-aged children who presented to the emergency department with an asthma exacerbation. METHODS We did a randomised controlled trial in patients aged 6-15 years who attended the regional emergency department in Auckland, New Zealand with an asthma exacerbation and were on regular inhaled corticosteroids. Using a simple, unrestricted block randomisation with block sizes of 200, we randomly assigned patients to receive an electronic monitoring device for use with their preventer inhaler with the audiovisual reminder functions either enabled to support adherence to inhaled corticosteroids (intervention group) or disabled (control group). Participants were followed up every 2 months for 6 months. The primary outcomes were adherence to preventive inhaled corticosteroids and number of days absent from school for any reason. Asthma control was assessed as a secondary outcome. All analyses were done in the intention-to-treat population. This trial is registered with the Australian New Zealand Clinical Trials Registry, number ACTRN12613001353785. FINDINGS The study took place between May 10, 2010, and Feb 26, 2012. We randomly assigned 220 patients, 110 to the intervention group and 110 to the control group. Median percentage adherence was 84% (10th percentile 54%, 90th percentile 96%) in the intervention group, compared with 30% (8%, 68%) in the control group (p<0·0001). The proportion of days absent from school for any reason was 1·9% (10th percentile 0·0%, 90th percentile 7·9%) in the intervention group and 1·7% (0·0%, 8·6%) in the control group. The change in asthma morbidity score from baseline to 6 months was significantly greater in the intervention group than in the control group (p=0·008), with a reduction of 2·0 points from a mean baseline score of 9·3 (SD 2·2) to 7·3 (2·1) in the intervention group, compared with a reduction of 1·2 points from a baseline of 9·2 (2·5) to 8·0 (2·2) in the control group. INTERPRETATION Use of an electronic monitoring device with an audiovisual reminder led to significant improvements in adherence to inhaled corticosteroids in school-aged children with asthma. This intervention could be beneficial for the improvement of asthma control in patients for whom poor asthma control is related to poor adherence.

Abstract
There is a growing body of research on manualized self-help interventions for bulimia nervosa (BN) and binge eating disorder (BED). Study and treatment dropout and adherence represent particular challenges in these studies. However, systematic investigations of the relationship between study, intervention and patient characteristics, participation, and intervention outcomes are lacking. We conducted a systematic literature review using electronic databases and hand searches of relevant journals. In metaregression analyses, we analyzed study dropout as well as more specific measures of treatment participation in manualized self-help interventions, their association with intervention characteristics (e.g. duration, guidance, intervention type [bibliotherapy, CD-ROM or Internet based intervention]) and their association with treatment outcomes. Seventy-three publications reporting on 50 different trials of manualized self-help interventions for binge eating and bulimia nervosa published through July 9th 2012 were identified. Across studies, dropout rates ranged from 1% to 88%. Study dropout rates were highest in CD-ROM interventions and lowest in Internet-based interventions. They were higher in samples of BN patients, samples of patients with higher degrees of dietary restraint at baseline, lower age, and lower body mass index. Between 6% and 88% of patients completed the intervention to which they had been assigned. None of the patient, study and intervention characteristics predicted intervention completion rates. Intervention outcomes were moderated by the provision of personal guidance by a health professional, the number of guidance sessions as well as participants' age, BMI, and eating disorder related attitudes (Restraint, Eating, Weight and Shape Concerns) at baseline (after adjusting for study dropout and intervention completion rates). Guidance particularly improved adherence and outcomes in samples of patients with bulimia nervosa; specialist guidance led to higher intervention completion rates and larger intervention effects on some outcomes than non-specialist guidance. Self-help interventions have a place in the treatment of BN and BED, especially if the features of their delivery and indications are considered carefully. To better determine who benefits most from what kind and "dosage" of self-help interventions, we recommend the use of consistent terminology as well as uniform standards for reporting adherence and participation in future self-help trials.

In the past decade, rapid technological developments have advanced electronic monitoring devices (EMD) for asthma inhalers beyond simple recording of actuations to providing adherence promotion features and detailed information about patterns of medication use. This article describes currently available EMDs, discusses their utility and limitations in assessing adherence, and describes the potential for EMD-based adherence promotion interventions in clinical settings. To date, the main use of EMDs has been in clinical research. In selected populations, simple EMD-based adherence interventions, delivered either through clinician-to-patient feedback about medication use or by direct-to-patient reminders for missed doses, can significantly improve adherence. Further work is now needed to determine the impact of EMDs on clinical outcomes and their cost-effectiveness and feasibility for different clinical settings, including in disadvantaged populations. If this evidence can be provided, then the use of EMDs could expand into the management of asthma in populations with high health care costs, eg, severe asthma. In the future, medication monitoring could help distinguish poor treatment response from poor adherence, guide prescribing decisions, and prompt providers to discuss barriers to adherence; electronic health records may provide the gateway for integrating medication-use monitoring into digital chronic care management.

Abstract
Research subjects do not always conform to research requirements. When their personal interests conflict with the demands of participation, some subjects surreptitiously break the rules. These subjects are subversive--they undermine the research endeavor. In rejecting the restrictions research imposes, subversive subjects diminish the value of research results. From one vantage point, subversive subjects engage in unethical behavior. They create risks to themselves and others; they also disregard ethical responsibilities to adhere to research agreements and tell the truth. At the same time, subversive subjects expose ethical problems in the design and conduct of clinical trials. Features of the research environment create fertile ground for subject subversion. Intensified policing and guidance are two common strategies for reducing subject subversion, but collaborative reforms are more consistent with the partnership model of clinical research.

Abstract
BACKGROUND Asthma guidelines advise addressing adherence at every visit, but no simple tools exist to assist clinicians in identifying key adherence-related beliefs or behaviours for individual patients. AIMS To identify potentially modifiable beliefs and behaviours that predict electronically recorded adherence with controller therapy. METHODS Patients aged ≥ 14 years with doctor-diagnosed asthma who were prescribed inhaled corticosteroid/long-acting β(2)-agonist (ICS/LABA) completed questionnaires on medication beliefs/behaviours, side-effects, Morisky adherence behaviour score and Asthma Control Test (ACT), and recorded spirometry. Adherence with ICS/LABA was measured electronically over 8 weeks. Predictors of adherence were identified by univariate and multivariate analyses. RESULTS 99/100 patients completed the study (57 female; forced expiratory volume in 1 s mean ± standard deviation 83 ± 23% predicted; ACT 19.9 ± 3.8). Mean electronically recorded adherence (n= 85) was 75% ± 25, and mean self-reported adherence was 85% ± 26%. Factor analysis of questionnaire items significantly associated with poor adherence identified seven themes: perceived necessity, safety concerns, acceptance of asthma chronicity/medication effectiveness, advice from friends/family, motivation/routine, ease of use and satisfaction with asthma management. Morisky score was moderately associated with actual adherence (r=-0.45, P < 0.0001). In regression analysis, 10 items independently predicted adherence (adjusted R(2) = 0.67; P < 0.001). Opinions of friends/family about the patient's medication use were strongly associated with poor adherence. Global concerns about ICS/LABA therapy were more predictive of poor adherence than were specific side-effects; the one-third of patients who reported experiencing side-effects from their steroid inhaler had lower adherence than others (mean 62% vs 81%; P= 0.015). CONCLUSIONS This study identified several specific beliefs and behaviours which clinicians could use for initiating patient-centred conversations about medication adherence in asthma.

Abstract
BACKGROUND Poor adherence to antiepileptic medications is associated with increased mortality and morbidity. In this review we focus on interventions designed to assist patients with adherence to antiepileptic medications. OBJECTIVES To determine the effectiveness of interventions aimed at improving adherence to antiepileptic medications in adults and children with epilepsy. SEARCH STRATEGY We searched the Epilepsy Group's Specialised Register (24 June 2010), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2010, Issue 2) and electronic databases: MEDLINE (OVID) (1950 to June 2010); EMBASE (OVID) (1980 to 2010 Week 24); CINAHL (1982 to June 2010) and PsycINFO (22 June 2010), and the reference lists of relevant articles. SELECTION CRITERIA Randomised or quasi-randomised controlled trials of adherence-enhancing interventions aimed at patients with clinical diagnosis of epilepsy (as defined in individual studies), of any age and of either gender, treated with antiepileptic drugs in a primary care, outpatient or other community setting. DATA COLLECTION AND ANALYSIS We screened titles and abstracts for eligibility. Two review authors independently extracted data and assessed each study according to the Cochrane criteria. The studies differed widely according to intervention and measures of adherence, therefore combining data was not appropriate. MAIN RESULTS Six trials met our inclusion criteria: five targeted adult epileptic patients with a combined patient number of 222 and one targeted parents of children with epilepsy (n = 51). Follow-up time was generally short: from one to six months. Two main types of intervention were examined: educational and behavioural modification. Each study compared treatment with no intervention 'usual care'. None compared one intervention with another. Due to heterogeneity between studies in terms of interventions and the methods used to measure adherence, we did not pool the results. Education and counselling of patients with epilepsy have shown mixed success. Behavioural interventions such as the use of intensive reminders and 'implementation intention' interventions provided more positive effects on adherence. AUTHORS' CONCLUSIONS Intensive reminders and 'implementation intention' interventions appear promising in enhancing adherence to antiepileptic mediations, however we need more reliable evidence on their efficacy from carefully designed randomised controlled trials before a firm conclusion can be reached.

Abstract
Despite the high percentage of incarcerated persons with mental illness, surprisingly little is known about effective ways to increase psychotropic medication adherence in prison and upon release. Currently, there are limited definitive data regarding psychotropic medication adherence patterns among incarcerated persons, and the data that exist often miss specific information on changes in behaviour, symptom management and adherence patterns over the length of a person's sentence, which has implications for post-release ability to live in the community. This paper presents the current literature regarding psychotropic medication adherence among mentally ill persons who are incarcerated. The factors identified in support of medication adherence, future clinical research and care strategies are provided.

Abstract
PURPOSE To assess patient adherence and behaviors with topical once-daily therapy for glaucoma. DESIGN Prospective, observational cohort study. PARTICIPANTS One hundred ninety-six patients with glaucoma who were being treated with a prostaglandin analog in 1 or both eyes at the Scheie or Wilmer Eye Institutes between August 2006 and June 2007. METHODS Detailed medical history was obtained from each patient. All subjects used the Travatan Dosing Aid (DA; Alcon, Fort Worth, TX) to administer travoprost as prescribed. Devices were collected at 3 months and the data of drop usage was downloaded using software provided with the dosing aid. Data were analyzed for the 8-week period starting 2 weeks after the enrollment visit and ending 2 weeks before the 3-month visit. MAIN OUTCOME MEASURES Assessment of adherence and patterns of drop usage as indicated by the DA. RESULTS A total of 282 subjects consented to be in the study and 86 (30%) withdrew before study completion or had device errors, leaving 196 subjects (70%) with evaluable data at 3 months. The overall mean (+/-standard deviation) adherence rate was 0.71 (+/-0.24), ranging from 0.02 to 0.97. One hundred nine of these patients (55.6%) took greater than 75% of the expected doses. Those with adherence of less than 50% of expected doses showed substantially increased dose taking immediately after the office visit and just before the return visit at 3 months (P = 0.03). The mean adherence rate estimates of the physician and patient self-report were 0.77 and 0.95, respectively. The agreement between the physician assessment and DA-recorded adherence rate showed poor correlation for individual cases (intraclass correlation coefficient, 0.09; 95% confidence interval, 0.00-0.19). CONCLUSIONS Nearly 45% of patients using an electronic monitoring device who knew they were being monitored and were provided free medication used their drops less than 75% of the time. Patients reported far higher medication use than their actual behavior. The ability of the physician to identify which persons are poorly adherent from their self-report or from other subjective clues is poor.

Abstract
CONTEXT Persistence with osteoporosis treatment is poor but is important for maximum benefit. OBJECTIVE The objective of the study was to assess the impact of physician reinforcement using bone turnover markers (BTMs) on persistence with risedronate treatment. DESIGN AND SETTING This was a 1-yr multinational prospective, open-label, blinded study in 171 osteoporosis centers in 21 countries. PATIENTS A total of 2382 postmenopausal women (65-80 yr old) with spine/hip T-score -2.5 or less or T-score -1.0 or less with a low-trauma fracture. INTERVENTION Intervention included calcium 500 mg/d, vitamin D 400 IU/d, and risedronate 5 mg/d for 1 yr. Centers were randomized to reinforcement (RE+) or no reinforcement (RE-). At 13 and 25 wk, reinforcement based on urinary N-telopeptide of type I collagen change from baseline was provided to the RE+ patients using the following response categories: good (>30% decrease), stable (-30% to +30% change), or poor (>30% increase). MAIN OUTCOME MEASURES Persistence assessed with electronic drug monitors was measured. RESULTS In the overall efficacy population (n=2302), persistence was unexpectedly high and was similar for both groups (RE-, 77%; RE+, 80%; P=0.160). A significant relationship between the type of message and persistence was observed (P=0.017). Compared with RE-, intervention based on a good BTM response was associated with a significant improvement in persistence [hazard ratio (HR) 0.71; 95% confidence interval (CI) 0.53-0.95]. Persistence was unchanged (HR 1.02; 95% CI 0.74-1.40) or lower (HR 2.22; 95% CI 1.27-3.89) when reinforcement was based on a stable or poor BTM response, respectively. Reinforcement was associated with a lower incidence of new radiologically determined vertebral fractures (odds ratio 0.4; 95% CI, 0.2-1.0). CONCLUSIONS Reinforcement using BTMs influences persistence with treatment in postmenopausal women with osteoporosis, depending on the BTM response observed.

Abstract
PURPOSE To compare the Morisky medication adherence questionnaire to pill counts as measures of adherence in the NET-PD futility clinical trials. BACKGROUND Like in other chronic diseases, non-adherence with medications occurs in Parkinson's disease (PD), although nonadherence has not been of significant concern in most PD clinical trials. The most common approach to assessment is to do a pill count at each visit. The simple, 4-question Morisky medication adherence questionnaire may provide an alternative approach to monitoring treatment adherence in PD. METHODS Adherence data from two NET-PD Phase II clinical trials enrolling a total of 413 participants were analyzed. The association between demographic and clinical characteristics and adherence was explored. RESULTS Ninety-percent of participants took 80% or more of the study drug. However, the Morisky medication adherence questionnaires showed 56% report high and 44% report medium adherence. Agreement between the two measures is fair (ICC = 0.40). CONCLUSIONS Overall adherence as assessed by pill count appears high. The Morisky medication adherence questionnaire may be useful in PD clinical trials, since it is moderately correlated to pill count and may be more sensitive to nonadherence.

Abstract
The use of drugs to treat human disease is a pursuit that extends back into our evolutionary ancestors. Drugs are powerful substances with a great capacity to cause harm if misused or overused. Even when used correctly, pharmaceuticals can elicit disputes about their relative harms and benefits in specific situations. The establishment of modern intermediaries – physicians or pharmacists – in the allocation of the most powerful drugs increases the potential for conflict between those who control the resource and those who desire access to it. The size and influence of the pharmaceutical–industrial complex places disproportionate power in those whose interests lie in promoting and expanding pharmaceutical use in society. The expense of certain drugs complicates equitable allocation, and the concentration of pharmaceutical power in Western, industrialized countries promotes research and drug discovery disproportionately for diseases that are prevalent in the wealthier nations. The increasing sophistication of drug action challenges the traditional model of using drugs as a means to treat pathological conditions and processes, and raises the specter of lifestyle and enhancement uses of pharmaceuticals. New means of drug discovery – such as the use of stem cells – have elicited debate about the relative values placed on the status of the embryo and the potential treatment for intractable conditions that could result from stem cell research. Finally, the overall emphasis on drugs as the first line defense against what ails us has provoked some societal soul-searching. In this chapter, we review some of the ethical issues attendant to drug production and distribution, including issues of safety, justice, economic inequality, and the changing demands for drugs that exceed therapeutic uses. Suggestions are made to make pharmaceutical companies more responsive to these issues and to make oversight bodies more responsible for their roles.

Abstract
Most ethics committees which review research protocols insist that potential research participants reserve unconditional or absolute 'right' of withdrawal at any time and without giving any reason. In this paper, I examine what consent means for research participation and a sense of commitment in relation to this right to withdraw. I suggest that, once consent has been given (and here I am excluding incompetent minors and adults), participants should not necessarily have unconditional or absolute rights to withdraw. This does not imply that there should be a complete absence of rights, or, indeed, an abandonment of the right to withdraw. The point of this paper is to show that the supposed unconditional or absolute nature of these rights may be self-defeating and so fail to respect the autonomy of participants. In addition, and on a more positive note, I suggest that, attaching certain conditions on the right to withdraw, may better respect the autonomy of these participants by underlining the idea that autonomy is more than mere whim or indifference to the fate of others. On the contrary, research staff are currently unable to 'push' participants, who may merely have logistical difficulties unrelated to the research itself, but who really want to stay the course, for fear of coercing them. Furthermore, researchers now try to 'screen out' people they think may be unreliable to protect the science of the study and so groups at risk of dropping out may be unfairly denied access to research treatments. I conclude that on-going negotiation between the relevant parties could be on balance the only truly acceptable way forward but concede certain important limitations to take into account.

Abstract
BACKGROUND Poor asthma outcomes often result from patients not following physician medication recommendations (ie, nonadherence). Estimates suggest that 50% of patients with asthma do not follow physician medication recommendations. OBJECTIVE To examine the rationale for making available objective medication adherence monitors for physicians to improve the quality of care for patients with severe persistent asthma. METHODS Review of the literature was undertaken in the following areas related to asthma: cost, morbidity, adherence, adherence monitoring, outcomes, and guidelines. RESULTS Patients with severe asthma are at risk for nonadherence because of (1) the use of multiple medications to control symptoms, (2) coexisting disease states, (3) the occurrence of depression and anxiety, and (4) the high cost of care. Research studies have demonstrated the effectiveness of objective monitoring as part of multiple clinical strategies to improve adherence and reduce morbidity and the cost of asthma care. Without objective adherence monitoring, physicians may not accurately assess nonadherence as the cause of treatment failure. This may lead to inappropriate increases in therapy, diagnostic studies, and consultations and may leave the patient at risk for persistent symptoms, morbidity, and death. CONCLUSION By correctly assessing nonadherence as the cause of treatment failure in patients with not only severe asthma but mild and moderate disease as well, practicing physicians may improve the quality of care provided.

Abstract
This article presents overviews of adherence or compliance in clinical care and research, focusing on the need to enhance research adherence. The scope of the clinical research enterprise and costs of conducting clinical research are summarized. Costs associated with suboptimal adherence in clinical care and research also are addressed, along with their implications for enhancing adherence. Methodological problems and statistical challenges (including intent-to-treat) associated with poor adherence are reviewed. Addressing social factors, regimen characteristics, behavioral patterns, and systems issues can affect adherence. Strategies for enhancing adherence in clinical research subjects, including pre-randomization screening, behavioral and educational interventions, monitoring, and enhancing subjects' status and contingencies for adhering are discussed. Integrating adherence-enhancing strategies throughout research phases, from pre-randomization screening during recruitment to endpoint, has the potential to improve the quality and outcome of research while limiting costs.

Abstract
OBJECTIVE Although poor medication adherence may contribute to inadequate diabetes control, ways to feasibly measure adherence in routine clinical practice have yet to be established. The present study was conducted to determine whether pharmacy claims-based measures of medication adherence are associated with clinical outcomes in patients with diabetes. RESEARCH DESIGN AND METHODS The study setting was a large, integrated delivery and financial system serving the residents of southeastern Michigan. The study population consisted of 677 randomly selected patients aged > or =18 years with a diagnosis of diabetes, hypercholesterolemia, and hypertension and who filled at least one prescription for either an antidiabetic, lipid-lowering, or antihypertensive drug in each of the 3 study years (1999-2001). The main outcome measures were HbA1c, LDL cholesterol levels, and blood pressure. RESULTS Nonadherent patients had both statistically and clinically worse outcomes than adherent patients. Even after adjusting for demographic and clinical characteristics, nonadherence was significantly associated with HbA1c and LDL cholesterol levels. A 10% increase in nonadherence to metformin and statins was associated with an increase of 0.14% in HbA1c and an increase of 4.9 mg/dl in LDL cholesterol levels. Nonadherence to ACE inhibitors was not significantly associated with blood pressure. CONCLUSIONS Claims-based measures of medication adherence are associated with clinical outcomes in patients with diabetes and may therefore prove to be useful in clinical practice. More research is needed on methods to introduce claims-based adherence measurements into routine clinical practice and how to use these measurements to effectively improve adherence and health outcomes in chronic care management.

Abstract
The Interaction Model of Client Health Behavior (IMCHB) has been established as a useful model in guiding research and development of individually tailored clinical interventions. The constructs of client singularity, client-provider interaction, and health outcomes guided an examination of medication decision-making by persons with serious mental illness (SMI). Client motivation is discussed as it relates to participation in the client-provider interaction and subsequent medication adherence and quality of life. Decisional control, the specific element of the client-provider interaction that affects medication decision-making, is considered in relation to consumer roles and responsibility for medication management. As psychotropic medications remain the single most effective treatment for reducing the active symptoms of psychosis, this look at medication decision-making may have significant implications for nursing.

Abstract
BACKGROUND Lack of adherence to blood pressure lowering medication is a major reason for poor control of hypertension worldwide. Interventions to improve adherence to antihypertensive medication have been evaluated in randomised trials but it is unclear which interventions are effective. OBJECTIVES To determine the effectiveness of interventions aiming to increase adherence to blood pressure lowering medication in adults with high blood pressure SEARCH STRATEGY All-language search of all articles (any year) in the Cochrane Controlled Trials Register (CCTR), MEDLINE, EMBASE, and CINAHL in April 2002. SELECTION CRITERIA RCTs of interventions to increase adherence to blood pressure lowering medication in adults with essential hypertension in primary care, with adherence to medication and blood pressure control as outcomes DATA COLLECTION AND ANALYSIS Two authors extracted data independently and in duplicate and assessed each study according to the criteria outlined by the Cochrane Collaboration Handbook. MAIN RESULTS We included 38 studies testing 58 different interventions and containing data on 15519 patients. The studies were conducted in nine countries between 1975 and 2000. The duration of follow-up ranged from two to 60 months. Due to heterogeneity between studies in terms of interventions and the methods used to measure adherence, we did not pool the results. Simplifying dosing regimens increased adherence in seven out of nine studies, with a relative increase in adherence of 8 per cent to 19.6 per cent. Motivational strategies were successful in 10 out of 24 studies with generally small increases in adherence up to a maximum of 23 per cent. Complex interventions involving more than one technique increased adherence in eight out of 18 studies, ranging from 5 per cent to a maximum of 41 per cent. Patient education alone seemed largely unsuccessful. REVIEWERS' CONCLUSIONS Reducing the number of daily doses appears to be effective in increasing adherence to blood pressure lowering medication and should be tried as a first line strategy, although there is less evidence of an effect on blood pressure reduction. Some motivational strategies and complex interventions appear promising, but we need more evidence on their effect through carefully designed RCTs.

Abstract
Chronic conditions dominate health care in most parts of the world, including the United States. Management of a disease by the patient is central to control of its effects. A wide range of influences in the person's social and physical environments enhance or impede management efforts. Interventions to improve management by patients can produce positive outcomes including better monitoring of a condition, fewer symptoms, enhanced physical and psychosocial functioning, and reduced health care use. Successful programs have been theory based. Self-regulation is a promising framework for the development of interventions. Nonetheless, serious gaps in understanding and improving disease management by patients remain because of an emphasis on clinical settings for program delivery, neglect of the factors beyond patient behavior that enable or deter effective management, limitations of study designs in much work to date, reliance on short-term rather than long-term assessments, and failure to evaluate the independent contribution of various program components.

Abstract
OBJECTIVES The primary objective of this study was to evaluate the viability of an electronic data logger to record the brushing episodes of patients receiving standardised oral hygiene instructions. The secondary objective was to estimate the compliance of a group of patients diagnosed with chronic periodontal disease with brushing time instructions for the daily use of a powered toothbrush over a 2-month period. MATERIAL AND METHODS 17 modified Philips Jordan Sensiflex 2000 powered toothbrushes (PTBs) were provided to patients (32-67 years) attending for non-surgical management of chronic periodontal disease. The PTBs incorporated an electronic data logger which recorded, for each individual brushing event: the length of time the brush was used (identifying the brushing speed setting); the maximum, minimum and average current during operation; and the time spent charging in between two consecutive brushing events. The patients were given detailed instructions with the PTB and were told to use it for 2 min each morning and 2 min in the evening. The patients returned for non-surgical management over two visits prior to reinforcement of the oral hygiene instructions 1 month after PTB allocation. Subjects were asked to complete a simple brushing diary to record their use of the toothbrush on a daily basis. After 2 months of using the PTBs at home, the brushes and diaries were collected and the data downloaded from the data loggers. RESULTS Of the 17 data loggers allocated, two recorded no information and two subjects did not return for the follow-up appointments. The data from the remaining 13 data loggers were evaluated for level of compliance. An event of brushing between 120 and 130 s was considered to be compliant, one of between 90 and 120 or 130-150 s was partially compliant and brushing for < 90 s or > 150 s was recorded as non-compliant. Percentage compliance for all the events (2087 recordings) was 34%, partial- and non-compliance were calculated as: 18%; 48% of events, respectively. CONCLUSION This data logger has provided previously unrecorded data on the brushing times for a group of patients using a powered toothbrush at home during non-surgical management of chronic periodontal disease. The data suggested that almost half (48%) of the brushing events recorded by the data loggers were greater than 30 s above or below the instructed brushing time.

Abstract
Adherence to treatment is an age-old issue in the health care provider-patient relationship. Although findings show that adherence has the potential to increase the efficacy of a treatment, is that the only consideration when examining the ethical questions surrounding adherence? What if the competent adult patient chooses not to adhere? The purpose of this paper is to examine the patient's choice to not adhere to a prescribed therapy. The author uses a hypothetical case as a way to identify and to challenge the assumptions underlying traditional adherence models.
