Abstract
BACKGROUND AND AIM Cardiovascular diseases are common causes of mortality in Saudi Arabia and the world. This study aims to assess medication compliance and regularity of follow-up for cardiovascular patients in the Jazan region. METHODOLOGY An analytical cross-sectional approach was used to target all registered cardiovascular patients attending the cardio clinic in a Jazan region hospital. Data were collected using an interview questionnaire developed by the researchers with the help of experts. The questionnaire included the patients' sociodemographic data, clinical characteristics, disease-related data, drugs, and appointments. RESULTS The study included 259 patients diagnosed with cardiac disease. About 53.7% of the patients were males. All the cases had the disease for one year or more. About 56% of the patients had no difficulty remembering their medications, while 44% had problems remembering to take them. More than half of the patients had good medication adherence, and 79.6% had good appointment adherence. Only 20.4% of patients had a poor adherence rate. CONCLUSION AND RECOMMENDATIONS The adherence rate for the patients' medication and appointments was satisfactory due to high patient awareness. On the other hand, poor adherence was related more to non-Saudi patients.

Abstract
BACKGROUND The onset of bipolar disorder (BD) is common during late adolescence and young adulthood (AYA). Suboptimal medication adherence is a critical yet modifiable risk factor for negative outcomes among AYAs with BD. METHODS This research used an iterative process (e.g., focus groups, advisory board, cognitive interviews) to modify an existing adherence intervention to address suboptimal adherence in AYAs with BD. The modified version of Customized Adherence Enhancement for Adolescents and Young Adults (CAE-AYA) will be compared to an Enhanced Treatment as Usual condition (ETAU) in 40 AYAs intervention using a 6-month prospective, randomized controlled trial (RCT) in a high-risk group of 16-21 year old AYAs with BD with demonstrated non-adherence to their prescribed BD medications. CONCLUSIONS This report describes the methodology and design of the ImprovinG adhereNce In adolescenTs with bipolar disordEr (IGNITE) study. If successful, the CAE-AYA approach has the potential to advance care for vulnerable youth with BD.

Interventions for improving management of chronic non-communicable diseases in Dikgale, a rural area in Limpopo Province, South Africa. BMC Health Serv Res 2018; 18:331. [PMID: 29728147 PMCID: PMC5935929 DOI: 10.1186/s12913-018-3085-y] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2016] [Accepted: 03/29/2018] [Indexed: 11/30/2022] Open
Abstract
Background Chronic disease management (CDM) is an approach to health care that keeps people as healthy as possible through the prevention, early detection and management of chronic diseases. The aim of this study was to develop interventions to improve management of chronic diseases in the form of an integrated, evidence-based chronic disease management model in Dikgale, a rural area of Limpopo Province in South Africa. Methods A multifaceted intervention, called ‘quality circles’ (QCs) was developed to improve the quality and the management of chronic diseases in the Dikgale Health and Demographic Surveillance System (HDSS). These QCs used the findings from previous studies which formed part of the larger project in the study area, namely, the quantitative study using STEPwise survey and qualitative studies using focus group discussions and semi-structured interviews. Results The findings from previous studies in Dikgale HDSS revealed that an epidemiological transition is occurring. Again, the most widely reported barriers from previous studies in this rural area were: lack of knowledge of NCDs; shortages of medication and shortages of nurses in the clinics, which results in patients having long waiting-time at clinics. Lack of training of health care providers on the management of chronic diseases and the lack of supervision by the district and provincial health managers, together with poor dissemination of guidelines, were contributing factors to the lack of knowledge of non-communicable diseases (NCDs) management among nurses and community health care workers (CHWs). Consideration of all of these findings led to the development of model which focuses on integrating nursing services, CHWs and traditional health practitioners (THPs), including a well-established clinical information system for health care providers. A novel aspect of the model is the inclusion of community ambassadors who are on treatment for NCDs and are, thus, repositories of knowledge who can serve as a bridge between health care workers and community members. Conclusion The model developed highlights the need for health interventions that aim to control risk factors at the population level, the need for availability of NCD-trained nurses, functional equipment and medication and a need to improve the link with traditional healers.

Incidence Rate of Post-Intubation Tracheal Stenosis in Patients Admitted to Five Intensive Care Units in Iran. IRANIAN RED CRESCENT MEDICAL JOURNAL 2016; 18:e37574. [PMID: 28144465 PMCID: PMC5253460 DOI: 10.5812/ircmj.37574] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/04/2016] [Revised: 03/29/2016] [Accepted: 04/09/2016] [Indexed: 11/30/2022]
Abstract
Background Tracheal stenosis is one of the worst complications associated with endotracheal intubation and it is the most common reason for reconstructive airway surgeries. Due to various local risk factors, the incidence rate of tracheal stenosis may vary in different countries. In order to estimate the incidence rate of post-intubation tracheal stenosis (PITS) in patients admitted to an intensive care unit (ICU), a follow-up study was planned. As there was no similar methodological model in the literature, a feasibility step was also designed to examine the whole project and to enhance the follow-up rate. Objectives To estimate the PITS incidence rate in patients admitted to ICUs, as well as to evaluate the feasibility of the study. Methods This prospective cohort study was conducted in five hospitals in two provinces (Tehran and Arak) of Iran from November 2011 to March 2013. All patients admitted to ICUs who underwent more than 24 hours of endotracheal intubation were included. Upon their discharge from the ICUs, the patients received oral and written educational materials intended to ensure a more successful follow-up. The patients were asked to come back for follow-up three months after their extubation, or sooner in case of any symptoms developing. Those with dyspnea or stridor underwent a bronchoscopy. The asymptomatic patients were given a spirometry and then they underwent a bronchoscopy if the flow-volume loop suggested airway stenosis. Results Some seventy-three patients (70% men) were included in the study. Multiple trauma secondary to motor vehicle accidents (52%) was the most common cause of intubation. Follow-ups were completed in only 14 (19.2%, CI = 0.109 - 0.300) patients. One patient (7%, CI = 0.007 - 0.288) developed symptomatic tracheal stenosis that was confirmed by bronchoscopy. The barriers to a successful follow-up were assessed on three levels: ineffective oral education upon discharge, improper usage of educational materials, and difficulties to attending follow-up visits. There were also some important obstacles in terms of human, time, material, and cost resources, as well as data management. Conclusions To enhance the follow-up rate, three strategies were proposed: patient-focused strategies such as emphasizing patient education upon discharge and providing rewards; structural-focused strategies such as scheduling home visits and uploading questionnaires onto the research center’s website; and provider-focused strategies such as selecting coordinators with good communication skills. All necessary resources should also be re-arranged for a multicenter national study.

Abstract
Medication noncompliance is a pervasive problem resulting in significant morbidity and mortality. There are many terms used to describe medication-taking behavior including compliance, adherence, intelligent compliance, and drug forgiveness. More recently, clinicians have focused on the need for a collaborative partnership with patients to attain medication adherence. Problems identified include the patient’s failing to initiate therapy, under using or overusing a drug, stopping a drug too soon, and mistiming or skipping doses. Adherence to medications is a complex health behavior. There are many risk factors associated with decreased compliance, and many strategies have been shown to improve drug-taking behavior and patient outcomes. By careful assessment, the pharmacist can identify the high-risk patient, recommend an individualized care plan, and provide the follow-up necessary to successfully change patient behavior. Pharmacists should focus on improving their own application of behavior modification principles and patient communication skills. Improved medication compliance results in improved humanistic, clinical, and economic outcomes.

Abstract
BACKGROUND Ongoing shortages of blood products may be addressed through additional donations. However, donation frequency rates are typically lower than medically possible. This preliminary study aims to determine voluntary nonremunerated whole blood (WB) and plasmapheresis donors' willingness, and subsequent facilitators and barriers, to make additional donations of a different type. STUDY DESIGN AND METHODS Forty individual telephone interviews were conducted posing two additional donation pattern scenarios: first, making a single and, second, making multiple plasmapheresis donations between WB donations. Stratified purposive sampling was conducted for four samples varying in donation experience: no-plasma, new-to-both-WB-and-plasma, new-to-plasma, and plasma donors. Interviews were analyzed yielding excellent (κ values > 0.81) inter-rater reliability. RESULTS Facilitators were more endorsed than barriers for a single but not multiple plasmapheresis donation. More new-to-both donors (n = 5) were willing to make multiple plasma donations between WB donations than others (n = 1 each) and identified fewer barriers (n = 3) than those more experienced in donation (n = 8 no plasma, n = 10 new to both, n = 11 plasma). Donors in the plasma sample were concerned about the subsequent reduced time between plasma donations by adding WB donations (n = 3). The no-plasma and new-to-plasma donors were concerned about the time commitment required (n = 3). CONCLUSION Current donors are willing to add different product donations but donation history influences their willingness to change. Early introduction of multiple donation types, variation in inventory levels, and addressing barriers will provide blood collection agencies with a novel and cost-effective inventory management strategy.

Cochrane Database Syst Rev 2014; 2022:CD007768. [PMID: 24777444 PMCID: PMC6491214 DOI: 10.1002/14651858.cd007768.pub3] [Citation(s) in RCA: 115] [Impact Index Per Article: 11.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/08/2023]
Abstract
BACKGROUND Many systematic reviews exist on interventions to improve safe and effective medicines use by consumers, but research is distributed across diseases, populations and settings. The scope and focus of such reviews also vary widely, creating challenges for decision-makers seeking to inform decisions by using the evidence on consumers' medicines use.This is an update of a 2011 overview of systematic reviews, which synthesises the evidence, irrespective of disease, medicine type, population or setting, on the effectiveness of interventions to improve consumers' medicines use. OBJECTIVES To assess the effects of interventions which target healthcare consumers to promote safe and effective medicines use, by synthesising review-level evidence. METHODS SEARCH METHODS We included systematic reviews published on the Cochrane Database of Systematic Reviews and the Database of Abstracts of Reviews of Effects. We identified relevant reviews by handsearching databases from their start dates to March 2012. SELECTION CRITERIA We screened and ranked reviews based on relevance to consumers' medicines use, using criteria developed for this overview. DATA COLLECTION AND ANALYSIS We used standardised forms to extract data, and assessed reviews for methodological quality using the AMSTAR tool. We used standardised language to summarise results within and across reviews; and gave bottom-line statements about intervention effectiveness. Two review authors screened and selected reviews, and extracted and analysed data. We used a taxonomy of interventions to categorise reviews and guide syntheses. MAIN RESULTS We included 75 systematic reviews of varied methodological quality. Reviews assessed interventions with diverse aims including support for behaviour change, risk minimisation and skills acquisition. No reviews aimed to promote systems-level consumer participation in medicines-related activities. Medicines adherence was the most frequently-reported outcome, but others such as knowledge, clinical and service-use outcomes were also reported. Adverse events were less commonly identified, while those associated with the interventions themselves, or costs, were rarely reported.Looking across reviews, for most outcomes, medicines self-monitoring and self-management programmes appear generally effective to improve medicines use, adherence, adverse events and clinical outcomes; and to reduce mortality in people self-managing antithrombotic therapy. However, some participants were unable to complete these interventions, suggesting they may not be suitable for everyone.Other promising interventions to improve adherence and other key medicines-use outcomes, which require further investigation to be more certain of their effects, include:· simplified dosing regimens: with positive effects on adherence;· interventions involving pharmacists in medicines management, such as medicines reviews (with positive effects on adherence and use, medicines problems and clinical outcomes) and pharmaceutical care services (consultation between pharmacist and patient to resolve medicines problems, develop a care plan and provide follow-up; with positive effects on adherence and knowledge).Several other strategies showed some positive effects, particularly relating to adherence, and other outcomes, but their effects were less consistent overall and so need further study. These included:· delayed antibiotic prescriptions: effective to decrease antibiotic use but with mixed effects on clinical outcomes, adverse effects and satisfaction;· practical strategies like reminders, cues and/or organisers, reminder packaging and material incentives: with positive, although somewhat mixed effects on adherence;· education delivered with self-management skills training, counselling, support, training or enhanced follow-up; information and counselling delivered together; or education/information as part of pharmacist-delivered packages of care: with positive effects on adherence, medicines use, clinical outcomes and knowledge, but with mixed effects in some studies;· financial incentives: with positive, but mixed, effects on adherence.Several strategies also showed promise in promoting immunisation uptake, but require further study to be more certain of their effects. These included organisational interventions; reminders and recall; financial incentives; home visits; free vaccination; lay health worker interventions; and facilitators working with physicians to promote immunisation uptake. Education and/or information strategies also showed some positive but even less consistent effects on immunisation uptake, and need further assessment of effectiveness and investigation of heterogeneity.There are many different potential pathways through which consumers' use of medicines could be targeted to improve outcomes, and simple interventions may be as effective as complex strategies. However, no single intervention assessed was effective to improve all medicines-use outcomes across all diseases, medicines, populations or settings.Even where interventions showed promise, the assembled evidence often only provided part of the picture: for example, simplified dosing regimens seem effective for improving adherence, but there is not yet sufficient information to identify an optimal regimen.In some instances interventions appear ineffective: for example, the evidence suggests that directly observed therapy may be generally ineffective for improving treatment completion, adherence or clinical outcomes.In other cases, interventions may have variable effects across outcomes. As an example, strategies providing information or education as single interventions appear ineffective to improve medicines adherence or clinical outcomes, but may be effective to improve knowledge; an important outcome for promoting consumers' informed medicines choices.Despite a doubling in the number of reviews included in this updated overview, uncertainty still exists about the effectiveness of many interventions, and the evidence on what works remains sparse for several populations, including children and young people, carers, and people with multimorbidity. AUTHORS' CONCLUSIONS This overview presents evidence from 75 reviews that have synthesised trials and other studies evaluating the effects of interventions to improve consumers' medicines use.Systematically assembling the evidence across reviews allows identification of effective or promising interventions to improve consumers' medicines use, as well as those for which the evidence indicates ineffectiveness or uncertainty.Decision makers faced with implementing interventions to improve consumers' medicines use can use this overview to inform decisions about which interventions may be most promising to improve particular outcomes. The intervention taxonomy may also assist people to consider the strategies available in relation to specific purposes, for example, gaining skills or being involved in decision making. Researchers and funders can use this overview to identify where more research is needed and assess its priority. The limitations of the available literature due to the lack of evidence for important outcomes and important populations, such as people with multimorbidity, should also be considered in practice and policy decisions.

Abstract
BACKGROUND This trial evaluated the effectiveness of an integrated intervention program that included a 3-to-5-minute nurse counseling session, copay relief cards, and a monthly newsletter on adherence to atorvastatin treatment. METHODS AND RESULTS A prospective, integrated (composed of nurse counseling, adherence tip sheet, copay relief card, opportunity to enroll in 12-week cholesterol management program) randomized interventional study was designed involving patients >21 years of age who were prescribed atorvastatin at a large single-specialty cardiovascular physician practice in Illinois from March 2010 to May 2011. Data from the practice's electronic medical record were matched/merged to IMS Health's longitudinal data. A total of 500 patients were enrolled (125 in the control arm; 375 in the intervention arm). After data linkage, 53 control patients and 155 intervention patients were included in the analysis. RESULTS Mean age was 67.8 years (control) and 69.5 years (intervention); 67.9% and 58.7%, respectively, were male. The mean 6-month adherence rate was 0.82 in both arms. The mean proportion of days covered for both the new-user control and intervention groups was the same, averaging 0.70 day (standard deviation [SD], 0.27 day); for continuing users, the proportion of days covered for the control group was 0.83 (SD, 0.24) and for the intervention group was 0.84 (SD, 0.22). For continuing users, the control group had mean persistent days of 151.6 (SD, 50.2) compared with 150.9 days (SD, 50.9) for the intervention group. New users had fewer persistent days (control 111.4 days, SD, 69.6 days; intervention 112.0 days, SD, 58.8 days) compared with continuing users. The Cox proportional hazards model of the risk of discontinuation with index therapy was not significantly different between the intervention and control groups (hazard ratio 0.83, P = 0.55). CONCLUSION The integrated intervention program did not significantly improve atorvastatin adherence relative to usual care in the studied patient population.

Abstract
Medication adherence has received a great deal of attention over the past several decades; however, its definition and measurement remain elusive. The authors propose a new definition of medication self-management that is guided by evidence from the field of health literacy. Specifically, a new conceptual model is introduced that deconstructs the tasks associated with taking prescription drugs; including the knowledge, skills and behaviors necessary for patients to correctly take medications and sustain use over time in ambulatory care. This model is then used to review and criticize current adherence measures as well as to offer guidance to future interventions promoting medication self-management, especially among patients with low literacy skills.

Abstract
BACKGROUND Up to 50 % of patients do not take medications as prescribed. Interventions to improve adherence are needed, with an understanding of which patients benefit most. OBJECTIVE To test the effect of two low-literacy interventions on medication adherence. DESIGN Randomized controlled trial, 2 × 2 factorial design. PARTICIPANTS Adults with coronary heart disease in an inner-city primary care clinic. INTERVENTIONS For 1 year, patients received usual care, refill reminder postcards, illustrated daily medication schedules, or both interventions. MAIN MEASURES The primary outcome was cardiovascular medication refill adherence, assessed by the cumulative medication gap (CMG). Patients with CMG<0.20 were considered adherent. We assessed the effect of the interventions overall and, post-hoc, in subgroups of interest. KEY RESULTS Most of the 435 participants were elderly (mean age=63.7 years), African-American (91 %), and read below the 9th-grade level (78 %). Among the 420 subjects (97 %) for whom CMG could be calculated, 138 (32.9 %) had CMG<0.20 during follow-up and were considered adherent. Overall, adherence did not differ significantly across treatments: 31.2 % in usual care, 28.3 % with mailed refill reminders, 34.2 % with illustrated medication schedules, and 36.9 % with both interventions. In post-hoc analyses, illustrated medication schedules led to significantly greater odds of adherence among patients who at baseline had more than eight medications (OR=2.2; 95 % CI, 1.21 to 4.04) or low self-efficacy for managing medications (OR=2.15; 95 % CI, 1.11 to 4.16); a trend was present among patients who reported non-adherence at baseline (OR=1.89; 95 % CI, 0.99 to 3.60). CONCLUSIONS The interventions did not improve adherence overall. Illustrated medication schedules may improve adherence among patients with low self-efficacy, polypharmacy, or baseline non-adherence, though this requires confirmation.

Abstract
BACKGROUND Numerous systematic reviews exist on interventions to improve consumers' medicines use, but this research is distributed across diseases, populations and settings. The scope and focus of reviews on consumers' medicines use also varies widely. Such differences create challenges for decision makers seeking review-level evidence to inform decisions about medicines use. OBJECTIVES To synthesise the evidence from systematic reviews on the effects of interventions which target healthcare consumers to promote evidence-based prescribing for, and medicines use, by consumers. We sought evidence on the effects on health and other outcomes for healthcare consumers, professionals and services. METHODS We included systematic reviews published on the Cochrane Database of Systematic Reviews and the Database of Abstracts of Reviews of Effects. We identified relevant reviews by handsearching both databases from start date to Issue 3 2008. We screened and ranked reviews based on relevance to consumers' medicines use, using criteria developed for this overview. Standardised forms were used to extract data, and reviews were assessed for methodological quality using the AMSTAR instrument. We used standardised language to summarise results within and across reviews; and a further synthesis step was used to give bottom-line statements about intervention effectiveness. Two review authors selected reviews, extracted and analysed data. We used a taxonomy of interventions to categorise reviews. MAIN RESULTS We included 37 reviews (18 Cochrane, 19 non-Cochrane), of varied methodological quality.Reviews assessed interventions with diverse aims including support for behaviour change, risk minimisation, skills acquisition and information provision. No reviews aimed to promote systems-level consumer participation in medicines-related activities. Medicines adherence was the most commonly reported outcome, but others such as clinical (health and wellbeing), service use and knowledge outcomes were also reported. Reviews rarely reported adverse events or harms, and the evidence was sparse for several populations, including children and young people, carers, and people with multimorbidity.Promising interventions to improve adherence and other key medicines use outcomes (eg adverse events, knowledge) included self-monitoring and self-management, simplified dosing and interventions directly involving pharmacists. Other strategies showed promise in relation to adherence but their effects were less consistent. These included reminders; education combined with self-management skills training, counselling or support; financial incentives; and lay health worker interventions.No interventions were effective to improve all medicines use outcomes across all diseases, populations or settings. For some interventions, such as information or education provided alone, the evidence suggests ineffectiveness; for many others there is insufficient evidence to determine effects on medicines use outcomes. AUTHORS' CONCLUSIONS Systematically assembling the evidence across reviews allows identification of effective or promising interventions to improve consumers' medicines use, as well as those for which the evidence indicates ineffectiveness or uncertainty.Decision makers faced with implementing interventions to improve consumers' medicines use can use this overview to inform these decisions and also to consider the range of interventions available; while researchers and funders can use this overview to determine where research is needed. However, the limitations of the literature relating to the lack of evidence for important outcomes and specific populations, such as people with multimorbidity, should also be considered.

Abstract
Non-adherence with recommended immunosuppressant medications is common post-pediatric liver transplant and is the most important reason for organ rejection in long-term survivors. However, there is currently no validated, standard method to measure adherence, with a well-defined threshold, making it extremely difficult to evaluate interventions to improve adherence. Previous studies have suggested that the degree of fluctuation of medication blood levels over time can provide an idea about how regularly the medication is being taken. The present study, conducted at UCLA medical center, sought to identify a specific threshold value of the s.d. of individual tacrolimus blood levels in pediatric liver transplant recipients which would be associated with rejection episodes in these patients. A threshold of 3.0 has been identified in other studies, and was supported by the analysis of retrospective data from 96 subjects. However, further analysis found that a s.d. of 2.5 appeared to have a better fit with the data. These findings suggest the utility of monitoring the s.d. of routine tacrolimus blood levels in pediatric liver transplant recipients for detecting non-adherence to immunosuppressant medication prior to clinical rejection, allowing earlier interventions.

Abstract
OBJECTIVES To characterize patient perceptions, related to eight self-management behaviours relevant for adults with ANCA-associated small vessel vasculitis (ANCA-SVV), and to determine if these perceptions were associated with performance of each behaviour. METHODS Adults with ANCA-SVV (n = 202) completed a self-administered questionnaire that assessed eight self-management behaviours (adherence to recommendations for medication, health service use, diet, exercise, infection avoidance and symptom monitoring; prompt reporting of symptoms and side effects; and adjusting activities in response to symptoms), perceptions about these behaviours, socio-demographics, clinical factors and social desirability bias. Descriptive statistics were generated to characterize patients' perceptions about difficulty of, importance of, and specific barriers to performing each behaviour. Regression analyses explored whether these variables were associated with performing each behaviour, controlling for potential confounders. RESULTS With few exceptions, higher perceived importance and lower perceived difficulty of each behaviour were associated with more frequent performance of the behaviour. For each behaviour, several specific barriers were frequently endorsed by patients and a number of these were associated with lower levels of self-management. CONCLUSION This study reveals that patient perceptions about the illness and its treatment influence ANCA-SVV self-management. Perceived barriers to medication, health services, diet and exercise adherence were similar to those in other illnesses. This study also provides insight into barriers experienced by patients in performing behaviours (infection avoidance, symptom monitoring, reporting symptoms and side-effects and adjusting activities) not often previously studied. How the identification of these barriers can help inform future interventions for ANCA-SVV patients is to be discussed.

Abstract
Self-management of chronic illness requires acquisition of self-care skills such as seeking knowledge, adhering to recommendations, practicing healthy behaviors, and life-long self-surveillance. This article describes the core problem and psychosocial processes by which parents transfer, and children take on, the responsibility for managing a chronic genetic condition. Individuals with Marfan syndrome (MFS), their parents, and health care providers were the sources of empirical data. A sample of 108 providers, parents, and individuals with MFS were recruited through a genetics clinic and the National Marfan Foundation. The core problem of "becoming fit and fitting in" is resolved via concurrent psychosocial processes: shifting perspective, shifting orientation, shifting sphere, shifting ownership, and shifting reasoning. Transition to self-management is more than planning the transfer of services from pediatric to adult care, and involves gradual changes in knowledge, attitudes, and behavior influenced by parents, peers, and health care providers. Transition to self-management is part of an evolving model of participation in life-long surveillance.

Abstract
AIMS The primary aim of this study was to describe the unintentional and intentional aspects of non-adherence in patients diagnosed with hypertension. A secondary aim was to examine the relationships between medication adherence and purposeful actions (intentional non-adherence), patterned behaviours (unintentional non-adherence) and demographic questionnaire variables. BACKGROUND Non-adherence to medications continues to be a significant health-care issue, the extent and consequences of which have been well documented. Despite considerable research over the past five decades, little progress has been made in solving this healthcare problem. Recent literature indicates that this lack of progress can be attributed to the fact that past research has concentrated solely upon either the unintentional or the intentional aspects of non-adherence, instead of addressing both facets simultaneously. METHODS A quantitative, descriptive, correlation research design was employed using Johnson's (2002) Medication Adherence Model as a theoretical framework. A convenience sample of 73 participants with hypertension, attending the outpatients' clinics of two university hospitals was recruited. Data were collected by means of a researcher administered questionnaire and analysed using the Statistical Package for Social Sciences. RESULTS High levels of medication adherence with a mean adherence score of 4.75 (maximum 5) were reported. Low and medium levels of purposeful actions and medium and high levels of patterned behaviours towards medication taking were found. Correlational analyses did not demonstrate statistically significant associations. CONCLUSIONS Both the intentional and unintentional dimensions of medication-taking are simultaneously considered by patients to varying levels when adhering to therapeutic regimens. This is an important research area for nurses as it facilitates an increased understanding of non-adherence and, in so doing, aids the uncovering of more effective interventions aimed at sustaining lifelong pharmacotherapy. RELEVANCE TO CLINICAL PRACTICE By acknowledging a broader approach to patient medication-taking, nurses will be able more effectively to assess and intervene in non-adherent behaviours and actions.

Abstract
BACKGROUND Patients' non-adherence to medical treatment remains a persistent problem. Many interventions to improve patient adherence are unsuccessful and sound theoretical foundations are lacking. Innovations in theory and practice are badly needed. A new and promising way could be to review the existing reviews of adherence to interventions and identify the underlying theories for effective interventions. That is the aim of our study. METHODS The study is a review of 38 systematic reviews of the effectiveness of adherence interventions published between 1990 and 2005. Electronic literature searches were conducted in Medline, Psychinfo, Embase and the Cochrane Library. Explicit inclusion and exclusion criteria were applied. The scope of the study is patient adherence to medical treatment in the cure and care sector. RESULTS Significant differences in the effectiveness of adherence interventions were found in 23 of the 38 systematic reviews. Effective interventions were found in each of four theoretical approaches to adherence interventions: technical, behavioural, educational and multi-faceted or complex interventions. Technical solutions, such as a simplification of the regimen, were often found to be effective, although that does not count for every therapeutic regimen.Overall, our results show that, firstly, there are effective adherence interventions without an explicit theoretical explanation of the operating mechanisms, for example technical solutions. Secondly, there are effective adherence interventions, which clearly stem from the behavioural theories, for example incentives and reminders. Thirdly, there are other theoretical models that seem plausible for explaining non-adherence, but not very effective in improving adherence behaviour. Fourthly, effective components within promising theories could not be identified because of the complexity of many adherence interventions and the lack of studies that explicitly compare theoretical components. CONCLUSION There is a scarcity of comparative studies explicitly contrasting theoretical models or their components. The relative weight of these theories and the effective components in the interventions designed to improve adherence, need to be assessed in future studies.

Abstract
Background In order to minimize the amount of incomplete follow-up data, reducing the non-compliance of participating physicians is one of the key issues for the data coordinating center in a multi-center trial. Identifying the physicians' non-compliance in advance is considered to be an important strategy for more efficient conduct of trials. In this study, we identified physicians' characteristics and factors associated with the need for individual visits to institutions to collect data or to complete information during two years of follow-up in a large Japanese investigator-initiated trial related to cardiovascular disease. Methods We categorized the physicians into two groups, "complier" and "non-complier". Odds ratios and corresponding 95% confidence intervals were calculated for 11 factors related to the characteristics of and compliance by physicians. Multiple logistic regression analysis was also performed. In addition, we evaluated the incremental cost for obtaining additional information of the non-compliant physicians. Results Three factors were identified in multiple logistic regression analysis as being significantly associated with compliance status: 1) prior participation in clinical trials (OR = 0.40 95%CI = 0.21–0.74); 2) physician opinion that the support system for case registration and follow-up was well organized (OR = 0.41 95%CI = 0.22–0.75); and 3) number of patients recruited (OR = 2.25 95%CI = 1.01–5.02). The actual incremental cost was about US $112,000 (14.4% of total routine follow-up costs) for the non-compliant physicians during the 2 years, or about US $570 per patient. Conclusion Investigator-initiated clinical trials have recently attracted great interest, but they often suffer from insufficient funding. If trial networks are to be well organized, it is important that trials are conducted more efficiently. We believe that our findings will be useful for reducing the additional burden associated with incomplete follow-up data and data lost to follow-up when planning future trials.

Abstract
Compliance, or adherence, as it relates to health care is the extent to which a person's behavior coincides with medical or health advice. Medication compliance is critical for all aspects of pediatrics, specifically in successful treatment, disease prevention, and health promotion. Compliance depends on the patient's and physician's committing to the same objectives. It is unfortunate that numerous studies and physician accounts reveal difficulties in achieving compliance with pediatric medication therapy. Medication compliance in pediatric patients ranges from 11% to 93%. At least one third of all patients fail to complete relatively short-term treatment regimens. Poor compliance places children at risk for problems such as continued disease, complicates the physician-patient relationship, and prevents accurate assessment of the quality of care provided. This article presents the issue in the context of its incidence of and barriers to compliance and provides general principles to improve compliance in pediatrics by improving communication and characteristics of the practice setting. A one-on-one relationship between physician and patient is needed for communication and improved compliance.

Abstract
BACKGROUND Previous studies investigating the effectiveness of compliance programs in patients with cardiovascular risk factors have been inconclusive and have not included economic analyses. The primary aim of this Open Label Primary Care Study: Rosuvastatin Based Compliance Initiatives To Achievements of LDL Goals (ORBITAL) study is to determine the long-term cost-effectiveness of a compliance-enhancing intervention in patients with hypercholesterolemia (HC). Secondary objectives include the assessment of compliance, cardiovascular events, and health-related quality of life. STUDY DESIGN A total of 7598 patients (56% men, age 60 +/- 10 years, and 44% women, 64 +/- 10 years) with HC requiring statin therapy according to the Second Joint European Guidelines were recruited at presentation to 1961 primary care physicians in Germany. Patients were randomized to rosuvastatin therapy with or without a compliance-enhancing program (including standardized contacts between the study center and patients, 9 mailings, 6 telephone calls, and access to a Web page and hotline) for 12 months. Following the intervention phase, there will be a 24-month observational period with patients receiving usual care. Baseline and 6-monthly follow-up assessments are to be obtained from patients and their physicians using standardized questionnaires to evaluate medical and economic parameters. Cumulative direct and indirect disease-related costs (including resource utilization for ambulatory, hospital, rehabilitative, and nursing care, medication, physiotherapy, and transportation, and loss of productivity) will be compared applying a societal perspective. CONCLUSIONS The results of this ORBITAL study will provide a basis to develop cost-effective compliance strategies and eventually improve medical care for patients with HC.

Abstract
OBJECTIVES The treatment alliance is the arena in which psychopharmacological and other therapeutic interventions occur. The nature and quality of the treatment alliance may affect adherence to treatment and the realization of the benefits of effective pharmacological treatment in clinical practice. It is an area that has attracted little systematic study, despite the available evidence suggesting that it plays a measurable role in clinical outcomes. METHODS A literature search was undertaken using Medline, Ovid, Psychinfo and Science Direct from 1975 to 2004. The following key words were used: bipolar disorder, patient adherence, non-adherence to medication, compliance, doctor-patient relationship, doctor-patient communication, treatment alliance, therapeutic alliance, chronic illness management, collaborative care, self-management, health beliefs, self-efficacy, self-determination, autonomy support, motivational interviewing. RESULTS Psychosocial interventions have demonstrated positive effects on adherence problems. Studies of the impact of the treatment alliance on outcomes in mental illness highlight the possibilities of fruitful research in this area in bipolar disorder. Different theoretical models of changing health related behaviour may inform approaches to the treatment alliance. CONCLUSIONS Results suggest the usefulness of a collaborative approach to the treatment alliance. Attention needs to be given to developing intervention models that target modifiable risk factors for non-adherence and address patient, clinician and illness related variables to enhance medication adherence in the treatment alliance. Refinement of these models through controlled evaluation in real world settings may lead to integration in health care delivery systems.

Abstract
OBJECTIVE Patient nonadherence to psychiatric medication is a key cause of relapse but clinicians do not appear to possess specific adherence skills. We sought to demonstrate that a brief training program on medication adherence strategies could improve the adherence skills, attitudes and knowledge of mental health clinicians. METHODS Twenty-three Tasmanian mental health workers were provided a 3 day training workshop on strategies to enhance patient adherence to medications (Medication Alliance). Pre- and post-training measures were taken of clinician knowledge about adherence strategies, ability to identify predictors of nonadherence, attitudes toward working with nonadherent patients, and optimism about treatment outcomes for patients. Videotapes of clinicians demonstrating key adherence therapy skills were also collected before and after training and blind-rated by two experienced therapists. RESULTS A series of paired samples t-tests indicated significant improvements in skills, knowledge and attitudes. CONCLUSIONS Compared with similar studies in the UK, Medication Alliance was found to be an effective and efficient training program. However, there is a need for further research to assess maintenance of training effects over time and patient outcomes.

OBJECTIVE Nonadherence to medications is a leading cause of morbidity in children and adolescents who have had a transplant, yet there are no published data about the use of different methods for detecting whether these children are taking their medications. There are also no published data about the age of transition at which a child assumes responsibility over taking the medications. This information is important if interventions to improve adherence are contemplated. METHODS We present an analysis of data obtained in the first year of the implementation of an adherence assessment protocol at a pediatric liver transplant clinic in a tertiary medical care center. Data were obtained for children and adolescents who had a liver transplant at least 1 year before the assessments took place. We used 5 adherence detection methods. The 4 subjective methods were self-reported, scaled questionnaires answered by nurses, physicians, caregivers, and patients. For the objective method, a standard deviation (SD) was calculated for tacrolimus blood levels obtained from each patient over time. A higher SD suggests increased variation among patients' blood levels and hence more erratic medication taking. We also asked the patients and caregivers who is responsible for taking the medications and what are the reasons for not taking them. The medical outcome measures were biopsy-proven rejection episodes, number of biopsies regardless of the results, number of hospital admissions, and number of in-patient days. RESULTS An analysis of 81 cases (258 assessments) revealed that the only method that predicted the medical outcome variables (biopsy-proven rejection and number of biopsies) was the SD of medication blood levels. Patients', clinicians', and caregivers' reports were not predictive. Clinicians' ratings of adherence were not correlated with patients' or caregivers'. The transition of responsibility for medication taking occurred approximately at the age of 12 years. Forgetfulness was cited as the most common reason for nonadherence by patients and caregivers; medication side effects were not frequently cited. CONCLUSIONS Our results indicate that clinical impression is not sufficient to determine whether children and adolescents are taking their medications after they have had a liver transplant. An objective assessment method should be used. Interventions targeting adherence should address the child's increasing role beginning in early adolescence. A clinical protocol incorporating objective assessments of adherence could potentially be implemented in other settings. It could form the basis for the evaluation of efficacy of interventions seeking to improve adherence to medications.

Abstract
This article describes how the resources in the Health Plan Employer and Data Information Set (HEDIS; a registered trademark of the National Committee for Quality Assurance) Performance NAVIGATOR for Controlling High Blood Pressure (HEDIS NAVIGATOR) developed by Merck & Co., Inc. assist managed care organizations in understanding and encouraging the active involvement of their members in adhering to a treatment plan developed in partnership by physicians and patients. (HEDIS is a set of standardized performance measures that enable purchasers and consumers to make informed decisions regarding the quality of managed care organizations.) The discussion uses the Health Belief and Transtheoretical Models as a framework to better understand patient behavior change. Targeted strategies to facilitate adherence are also addressed. Examples of structured programs using nationally recommended guidelines and HEDIS NAVIGATOR resources are included to illustrate coordinated efforts to assist patients with high blood pressure adhere to their treatment plan and help managed care organizations improve patient outcomes and HEDIS scores.

Abstract
The goal of this study was to determine if neuropsychological function is associated with adherence to prescribed medication. Altogether, 79 patients with type II diabetes at a VA primary care clinic had adherence to the antihyperglycemic drug metformin measured with MEMS caps over a 4-week period. They completed several tests of neuropsychological function: Mini-Mental Status Exam (MMSE), Trails A and B, Stroop, Digit Span, Digit Symbol, and Grooved Pegboard. In separate multivariate analyses, Stroop word score and time to complete Trails B were independently associated with adherence, as was age. Secondary analyses of the relationship between neuropsychological variables and other adherence-related measures were conducted. Low scores on the MMSE and non-Caucasian ethnicity were associated with missed appointments. None of the neuropsychological variables were associated with glycosylated hemoglobin. These results suggest that cognitive abilities should be considered when counseling patients concerning their adherence.

Abstract
PURPOSE To investigate compliance to the prescribed dose-fractionation schedule in five randomized controlled trials of altered fractionation in radiotherapy for head-and-neck carcinoma. METHODS AND MATERIALS Individual patient data from 2566 patients participating in the European Organization for Research and Treatment of Cancer (EORTC) 22791, EORTC 22811, EORTC 22851, Princess Margaret Hospital (PMH), and continuous hyperfractionated accelerated radiotherapy (CHART) head-and-neck trials were merged in the fractionation IMPACT (Intergroup Merger of Patient data from Altered or Conventional Treatment schedules) study database. The ideal treatment time was defined as the minimum time required to deliver a prescribed schedule. Compliance to the prescribed overall treatment time was quantified as the difference between the actual and the ideal overall time. An overall measure of compliance in an individual patient, the total dose lost (TDL), was calculated as the dose lost due to prolongation of therapy (assuming a D(prolif) of 0.64 Gy/day) plus the difference between the prescribed and the actual dose given. RESULTS The time in excess of the ideal ranged up to 97 days (average 3.9 days), and 25% of the patients had delays of 6 days or more. World Health Organization (WHO) performance status and nodal stage had a significant effect on TDL. TDL was significantly higher in the conventional than in the altered arm of the EORTC 22851 and CHART trials. In the PMH trial, TDL was significantly higher in the hyperfractionation than in the conventional arm. Centers participating in the three EORTC trials varied significantly in their compliance. There was a significant improvement in compliance in patients treated more recently. CONCLUSIONS Even in randomized controlled trials, compliance to the prescribed radiation therapy schedule may be relatively poor, especially after conventional fractionation. This affects the interpretation of the outcome of these trials.

Abstract
Cardiac behavioral medicine is the application of behavioral and psychosocial principles to the prevention and treatment of heart disease. Most biomedical cardiovascular risk factors (e.g., high blood lipids, high blood pressure, diabetes) require behavioral and medical interventions. Other risks, including obesity, high-fat eating pattern, smoking, and inactivity, clearly require lifestyle change. Behavioral medicine screening and intervention have been applied to psychosocial risk factors such as depression, hostility, and social isolation. Appropriate assessment of risk factors is essential because research has demonstrated successful prevention of heart disease and reduction of morbidity and mortality in patients with existing disease. Behavioral interventions have been beneficial in improving cardiac outcomes by enhancing compliance with medication taking and dietary/exercise recommendations. Future needs include the study of psychosocial factors in women and ethnic minorities with heart disease and the integration of behavioral medicine with newer medical technologies designed to detect subclinical biomarkers of heart disease.

Abstract
Some of the many ways in which mathematical biology and statistics have been used in investigating the acquired immunodeficiency syndrome (AIDS) epidemic are reviewed. Aspects of the spread of the disease via social and sexual networks are discussed. The different kinds of data involved are critically compared. Some studies of the incubation period are briefly reviewed and some comments made on the role of adherence to therapy.
