Rating Scales for Medication Adherence in Parkinson's Disease: A Systematic Review for Critique and Recommendations. Mov Disord Clin Pract 2023; 10:175-189. [PMID: 36825050 PMCID: PMC9941935 DOI: 10.1002/mdc3.13586] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 08/27/2022] [Accepted: 09/06/2022] [Indexed: 11/12/2022] Open
Abstract
Background Behaviors interfering with medication adherence (MA) are common and often complex in Parkinson's disease (PD), negatively affecting quality of life and undermining the value of clinical trials. The Clinical Outcome Assessments (COA) Scientific Evaluation Committee of the International Parkinson and Movement Disorder Society (MDS) commissioned the assessment of MA rating scales to recommend the use in PD. Objective Critically review the measurement properties of rating scales used to assess MA in PD and to issue recommendations. Methods We conducted systematic review across seven databases to identify structured scales to assess MA in PD. Eligible studies were critically appraised for methodological quality using the Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) Risk of Bias checklist. Standards for good measurement properties of the selected scales were summarized narratively using the COSMIN, the MDS-COA Committee methodology, the World Health Organization concepts, and the Ascertaining Barriers to Compliance taxonomy. The certainty of the evidence was determined using the modified Grades of Recommendation, Assessment, Development and Evaluation approach with final assessments (highest to lowest) of "Recommended," "Suggested" and "Listed". Results Of the nine reviewed scales, none met the designation "Recommended". The Morisky Medication Adherence Scale (MMAS-8); Beliefs Related to Medications Adherence questionnaire, Beliefs about Medication Questionnaire, Medication Adherence Rating Scale, and Satisfaction with Information on Medicines Scale were rated "Suggested". Conclusions We suggest further work focusing on resolving the problems of the suggested scales or developing a new scale meeting all required criteria.

Nurse-led intervention to decrease drug use among LTBI positive homeless adults. Public Health Nurs 2022; 39:778-787. [PMID: 35014087 DOI: 10.1111/phn.13044] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Revised: 12/09/2021] [Accepted: 12/11/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND People experiencing homelessness (PEH) are disproportionately diagnosed with active tuberculosis. While promoting latent tuberculosis infection (LTBI) treatment has been a call to action, PEH engaging in substance use often experience challenges in completing LTBI treatment. METHODS In this non-randomized single arm study, we tested an innovative, community-based, nurse-led community health worker (RN-CHW) model, on reducing drug use among 50 PEH, residing in homeless shelters or living on the streets in Los Angeles. Follow-up was at 3- and 6- months. RESULTS Findings revealed significant and ongoing decrease in any drug use (odds ratio [OR] = 0.30; 95% confidence interval [CI] = 0.14-0.68); p = .004), amphetamine use (OR = 0.14; 95% CI = 0.02-0.81; p = .029), cannabis use (OR = 0.26; 95% CI = 0.12-0.57; p = .001) and methamphetamine use (OR = 0.30; 95% CI = 0.10-0.90; p = .031) at 6-month follow-up. CONCLUSIONS To our knowledge, this pilot study is the first to evaluate the impact a RN-CHW delivered intervention on reduction in drug use among PEH enrolled in a LTBI intervention. LTBI interventions may serve as an entryway into reduction in drug use among this underserved population.

Abstract
BACKGROUND Tuberculosis (TB) disproportionately affects marginalized and impoverished homeless adults. Although active TB can be prevented by treating latent TB infection (LTBI), individual factors, such as high prevalence of depression and anxiety, drug and alcohol use, and unstable housing, lead to poor LTBI treatment adherence and completion among homeless adults. OBJECTIVES We hypothesized that the delivery of a tailored nurse-led, community health worker (RN/CHW) program across the LTBI continuum of care (e.g., screening, diagnosis, and treatment) that delivers 3HP treatment (3HP: rifapentine plus isoniazid) for homeless adults (e.g., sheltered and unsheltered) and is tailored to their health and social service needs will overcome existing treatment completion barriers. We also hypothesized that mental health symptoms (e.g., depression and anxiety), drug use score, and problematic alcohol use will decline over time among clients receiving this treatment. METHODS We assessed the effect of delivering a theoretically guided, RN/CHW-based, single-arm study among eligible LTBI-positive homeless adults (N = 50) on completion of a weekly, directly observed, 12-dose 3HP LTBI treatment in Central City East (Skid Row). Completing 3HP treatment was compared to the only known historical, clinic-based control that obtained 65% completion among homeless adults. Secondary outcomes included drug and alcohol use, depression, and anxiety. RESULTS The RN/CHW program achieved a 91.8% 3HP treatment completion rate among homeless adults. Younger homeless adults (<50 years old) were less likely to complete 3HP treatment compared to those who were older. Neither drug use, depression, nor anxiety was associated with 3HP treatment completion. Decrease in anxiety was observed at 3 months, but not at 6 months, compared to baseline. DISCUSSION To our knowledge, the pilot study is the first to evaluate an effective RN/CHW-delivered, community-based intervention, which can reduce the burden of active TB for homeless adults.

Abstract
OBJECTIVE The objective of the review is to evaluate the measurement properties of rating scales that have been used to assess the components of medication adherence in patients with Parkinson's disease. INTRODUCTION Drug therapy is a central strategy in the control of Parkinson's disease symptoms. Measuring behaviors related to medication adherence in patients with Parkinson's disease is vital to understanding the therapeutic response, making it necessary to define which instrument offers the most reliable and valid screening. INCLUSION CRITERIA Studies in English and Portuguese using structured rating scales to assess medication adherence in people with Parkinson's disease will be included. Studies including data from patients with different diseases in addition to Parkinson's disease, will be included only if data are clearly available for each disorder covered. Study protocols, letters to the editors, reviews, and studies with clinical judgment scales but no operationally defined anchor points will be excluded. METHODS A three-step search strategy will be utilized. Databases that will be utilized are MEDLINE (PubMed), LILACS (BVS Portal), PsycINFO (APA PsycNet), CINAHL (EBSCO), Web of Science (Clarivate Analytics), Embase, and Scopus (Elsevier). The search strategy will be presented using a PRISMA flow diagram. Eligible studies will be critically appraised for methodological quality using the COSMIN Risk of Bias checklist. Criteria for good measurement properties of the selected scales will be summarized narratively using COSMIN, the Movement Disorder Society Rating Scale Program Committee methodology, the World Health Organization concepts, and the ABC taxonomy of medication adherence. The certainty of the evidence will be determined using the modified GRADE. SYSTEMATIC REVIEW REGISTRATION NUMBER PROSPERO (CRD42021211099).

Abstract
Homeless persons have disproportionate rates of latent tuberculosis infection (LTBI). LTBI treatment can prevent and reduce active tuberculosis spread. We examined associations between mental health, social support, and perceptions of general health in 50 LTBI-positive, homeless adults enrolled in LTBI treatment. Depression and anxiety prevalence were 40% and 48%, respectively. Depression was negatively associated with general health, positive social interaction, and tangible, emotional/informational, and total social support, and positively associated with severe substance use (ps < 0.05). Anxiety was negatively associated with emotional/informational, tangible and total social support, and positively associated with severe substance use (ps < 0.05). Mental health services may help improve LTBI interventions.

Non-completion of latent tuberculosis infection treatment among Vietnamese immigrants in Southern California: A retrospective study. Public Health Nurs 2020; 37:846-853. [PMID: 32896018 DOI: 10.1111/phn.12798] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2020] [Revised: 08/11/2020] [Accepted: 08/12/2020] [Indexed: 11/28/2022]
Abstract
OBJECTIVES To examine socio-demographic and health-related factors associated with latent tuberculosis infection (LTBI) treatment refusal, non-initiation, and non-completion among a cohort of Vietnamese immigrants. DESIGN This is a retrospective cohort study in which LTBI charts were reviewed at a public health clinic in Orange County, California between January 2010 and August 2011. SAMPLE Altogether, 474 patient charts with documented LTBI treatment were reviewed for patients who met the inclusion criteria. MEASUREMENTS Univariate and multivariate analyses were used to identify socio-demographic and health-related factors associated with LTBI treatment refusal, non-initiation, and non-completion. RESULTS Of the 474 charts reviewed, 171(36.1%) patients refused LTBI treatment and 21(6.9%) accepted but did not initiate. Of the 282 that started treatment, 62 (22.0%) did not complete the regimen prescribed. The primary barrier documented for treatment refusal and non-completion was concern about medication side effects. Other barriers to treatment non-completion include transportation issues and conflicts with travel plans or work schedules. CONCLUSIONS Community and public health nurses working with the Vietnamese immigrant population can play a vital role in improving patients' LTBI treatment acceptance, initiation, and completion. A proactive approach to addressing barriers and potential medication side effects can improve overall treatment success.

Abstract
BACKGROUND The burden of hypertension is escalating, and control rates are poor in low- and middle-income countries. Cardiovascular mortality is high in rural areas. METHODS We conducted a cluster-randomized, controlled trial in rural districts in Bangladesh, Pakistan, and Sri Lanka. A total of 30 communities were randomly assigned to either a multicomponent intervention (intervention group) or usual care (control group). The intervention involved home visits by trained government community health workers for blood-pressure monitoring and counseling, training of physicians, and care coordination in the public sector. A total of 2645 adults with hypertension were enrolled. The primary outcome was reduction in systolic blood pressure at 24 months. Follow-up at 24 months was completed for more than 90% of the participants. RESULTS At baseline, the mean systolic blood pressure was 146.7 mm Hg in the intervention group and 144.7 mm Hg in the control group. At 24 months, the mean systolic blood pressure fell by 9.0 mm Hg in the intervention group and by 3.9 mm Hg in the control group; the mean reduction was 5.2 mm Hg greater with the intervention (95% confidence interval [CI], 3.2 to 7.1; P<0.001). The mean reduction in diastolic blood pressure was 2.8 mm Hg greater in the intervention group than in the control group (95% CI, 1.7 to 3.9). Blood-pressure control (<140/90 mm Hg) was achieved in 53.2% of the participants in the intervention group, as compared with 43.7% of those in the control group (relative risk, 1.22; 95% CI, 1.10 to 1.35). All-cause mortality was 2.9% in the intervention group and 4.3% in the control group. CONCLUSIONS In rural communities in Bangladesh, Pakistan, and Sri Lanka, a multicomponent intervention that was centered on proactive home visits by trained government community health workers who were linked with existing public health care infrastructure led to a greater reduction in blood pressure than usual care among adults with hypertension.

Abstract
Background Preconception care, including family planning, is a vital component of healthcare for women of reproductive age. An average female spends the majority of her reproductive life trying to prevent a pregnancy. In order to prevent unintended pregnancy, women often rely on the use of hormonal contraceptives. In the United States, the majority of hormonal contraceptive users are prescribed oral contraceptive pills (OCPs). Reduced adherence to OCPs decreases their ability to prevent pregnancy. The study aimed to measure OCP adherence among female college students, and explore the relationship between OCP adherence, knowledge, and self-efficacy. Methods This cross-sectional study recruited a random sample of female college students to participate in an online survey. OCP adherence was based on the 8-item Morisky Medication Adherence Scale (MMAS-8). Secondary reporting of medication adherence included participant reports of the number of missed OCP doses in the previous month and typical month of use. Results Of the 5000 invited, 1559 (31.3%) completed the survey. Of those responding, 670 (41.3%) reported use of OCPs. A total of 293 (44.3%) OCP users met criteria for low adherence, 241 (36.4%) met criteria for medium adherence, and 128 (19.3%) met criteria for high adherence. Those with high adherence had higher self-efficacy (P < 0.001) and perceived knowledge (p < 0.001). After controlling for other factors, self-efficacy (b = .37) and perceived knowledge (b = .09) remained associated with OCP adherence. Conclusion Less than 20% of respondents met the criteria for high adherence to OCPs. Self-efficacy and knowledge were associated with higher OCP adherence. Targeted interventions from healthcare providers, health educators, and other adherence related media to increase the knowledge and self-efficacy of patients using OCPs may improve adherence rates. Additional research is needed to evaluate the impact of innovative interventions focused on social and behavioral patient factors, like knowledge and self-efficacy, on adherence to OCPs.

Abstract
BACKGROUND Non-adherence to long-term therapy for chronic illnesses is considered the major reason why patients fail to reach their clinical goals, resulting in suboptimal health outcomes, death, and extra costs on the health care systems. Knowledge about the disease and prescription medications, an understanding of the reason the medication is needed, and good expectations or attitudes toward treatment, all contribute to a better medication-taking behavior and are associated with higher rates of adherence. OBJECTIVE This study examines the relationship between knowledge and adherence of patients receiving long-term therapy for one or more chronic illnesses in Jordan. SETTINGS The study was conducted in the out-patient clinics of two Jordanian hospitals (The University of Jordan Hospital and Jordan Hospital). METHODS This was a cross-sectional study that included 902 patients. The correlation between patients' knowledge about their chronic medications and adherence was assessed. Effects of several sociodemographic characteristics were investigated in regard to knowledge and adherence. MAIN OUTCOME MEASURES Knowledge was assessed by a modified version of the McPherson index, and the Morisky Medication Adherence Scale was used to assess medication adherence. RESULTS A significant correlation was found between patients' knowledge and their adherence to medications (r = 0.357, p < 0.001). Most of the participants had low adherence. Younger age, higher education levels, high income, fewer medications and diseases were significant predictors of higher knowledge levels. Knowledgeable patients were found to be twice as likely to have moderate-to-high adherence as their unknowledgeable counterparts. Similarly, high income and higher education were associated with higher adherence scores. CONCLUSION Forgetfulness and aversion toward medications were the most common barriers to medication adherence. This implicates that clinicians and health care policy makers should direct their effort toward two main strategies to improve adherence increasing awareness and education of effective ways to remind patients about their medications.

Health promotion interventions and policies addressing excessive alcohol use: a systematic review of national and global evidence as a guide to health-care reform in China. Addiction 2015; 110 Suppl 1:68-78.

Abstract
AIMS Steady increases in alcohol consumption and related problems are likely to accompany China's rapid epidemiological transition and profit-based marketing activities. We reviewed research on health promotion interventions and policies to address excessive drinking and to guide health-care reform. METHODS We searched Chinese- and English-language databases and included 21 studies in China published between 1980 and 2013 that covered each policy area from the World Health Organization (WHO) Global Strategy to Reduce the Harmful Use of Alcohol. We evaluated and compared preventive interventions to the global alcohol literature for cross-national applicability. RESULTS In contrast with hundreds of studies in the global literature, 11 of 12 studies from mainland China were published in Chinese; six of 10 in English were on taxation from Taiwan or Hong Kong. Most studies demonstrated effectiveness in reducing excessive drinking, and some reported the reduction of health problems. Seven were randomized controlled trials. Studies targeted schools, drink-driving, work-places, the health sector and taxation. CONCLUSIONS China is the world's largest alcohol market, yet there has been little growth in alcohol policy research related to health promotion interventions over the past decade. Guided by a public health approach, the WHO Global Strategy and health reform experience in Russia, Australia, Mexico and the United States, China could improve its public health response through better coordination and implementation of surveillance and evidence-based research, and through programmatic and legal responses such as public health law research, screening and early intervention within health systems and the implementation of effective alcohol control strategies.

Abstract
OBJECTIVES To determine whether sociodemographic, clinical, healthcare system, psychosocial, and behavioral factors are differentially associated with low antihypertensive medication adherence scores in older men and women. DESIGN Cross-sectional analysis of baseline data. SETTING Cohort Study of Medication Adherence in Older Adults (N = 2,194). MEASUREMENTS Low antihypertensive medication adherence was defined as a score less than 6 on the 8-item Morisky Medication Adherence Scale. Information on risk factors for low adherence was collected using telephone surveys and administrative databases. RESULTS The prevalence of low medication adherence scores did not differ according to sex (women, 15.0%; men 13.1%; P = .21). In sex-specific multivariable models, having problems with medication cost and practicing fewer lifestyle modifications for blood pressure control were associated with low adherence scores in men and women. Factors associated with low adherence scores in men but not women were poor sexual functioning (odds ratio (OR) = 2.03, 95% confidence interval (CI) = 1.31-3.16 for men and OR = 1.28, 95% CI = 0.90-1.82 for women), and body mass index of 25.0 kg/m(2) or more (OR = 3.23, 95% CI = 1.59-6.59 for men; OR = 1.23, 95% CI = 0.82-1.85 for women). Factors associated with low adherence scores in women but not men included dissatisfaction with communication with their healthcare provider (OR = 1.75, 95% CI = 1.16-2.65 for women; OR = 1.16, 95% CI = 0.57-2.34 for men) and depressive symptoms (OR = 2.29, 95% CI = 1.55-3.38 for women; OR = 0.93, 95% CI = 0.48-1.80 for men). CONCLUSION Factors associated with low antihypertensive medication adherence scores differed according to sex. Interventions designed to improve adherence in older adults should be customized to account for the sex of the target population.

Abstract
Background Self-report scales are used to assess medication adherence. Data on how to discriminate change in self-reported adherence over time from random variability are limited. Objective: To determine the minimal detectable change for scores on the 8-item Morisky Medication Adherence Scale (MMAS-8). Methods: The MMAS-8 was administered twice, using a standard telephone script, with administration separated by 14-22 days, to 210 participants taking antihypertensive medication in the CoSMO (Cohort Study of Medication Adherence among Older Adults). MMAS-8 scores were calculated and participants were grouped into previously defined categories (<6, 6 to <8, and 8 for low, medium, and high adherence). Results: The mean (SD) age of participants was 78.1 (5.8) years, 43.8% were black, and 68.1% were women. Overall, 8.1% (17/210), 16.2% (34/210), and 51.0% (107/210) of participants had low, medium, and high MMAS-8 scores, respectively, at both survey administrations (overall agreement 75.2%; 158/210). The weighted κ statistic was 0.63 (95% CI 0.53 to 0.72). The intraclass correlation coefficient was 0.78. The within-person standard error of the mean for change in MMAS-8 scores was 0.81, which equated to a minimal detectable change of 1.98 points. Only 4.3% (9/210) of the participants had a change in MMAS-8 of 2 or more points between survey administrations. Conclusions: Within-person changes in MMAS-8 scores of 2 or more points over time may represent a real change in antihypertensive medication adherence.

Abstract
AIMS The Blood Pressure Success Zone (BPSZ) Program, a nationwide initiative, provides education in addition to a complimentary trial of one of three antihypertensive medications. The BPSZ Longitudinal Observational Study of Success (BPSZ-BLISS) aims to evaluate blood pressure (BP) control, adherence, persistence and patient satisfaction in a representative subset of BPSZ Program participants. The BPSZ-BLISS study design is described here. METHODS A total of 20,000 physicians were invited to participate in the study. Using a call centre supported Interactive Voice Response System (IVRS), physicians report BP and other data at enrolment and every usual care visit up to 12 +/- 2 months; subjects self-report BPs, persistence, adherence and treatment satisfaction at 3, 6 and 12 months post-BPSZ Program enrolment. In addition to BPSZ Program enrolment medications, physicians prescribe antihypertensive medications and schedule visits as per usual care. The General Electric Healthcare database will be used as an external reference. RESULTS After 18 months, over 700 IRB approved physicians consented and enrolled 10,067 eligible subjects (48% male; mean age 56 years; 27% newly diagnosed); 97% of physicians and 78% of subjects successfully entered IVRS enrolment data. Automated IVRS validations have maintained data quality (< 5% error on key variables). Enrolment was closed 30 April 2007; study completion is scheduled for June 2008. CONCLUSIONS The evaluation of large-scale health education programmes requires innovative methodologies and data management and quality control processes. The BPSZ-BLISS design can provide insights into the conceptualisation and planning of similar studies.

Abstract
The purpose of this study was to examine predictors of screening results for depressive symptoms in a Los Angeles homeless population with latent tuberculosis (TB). Four hundred and fifteen homeless adults participating in a nurse case managed intervention were included in this analysis. Logistic regression results indicated that those who reported a physical health limitation, multiple sex partners, daily drug use, alcohol dependence, or not having completed high school, were more likely to screen positive. Social support from non-drug users was protective. Given the importance of adherence to TB treatment regimens, the high prevalence of a positive screening for depressive symptoms in the homeless and the potential for depression to reduce adherence rates, routine screening and treatment for depression in high risk homeless adults being treated for TB may be warranted.

Abstract
PURPOSE OF REVIEW Efficacious pharmacologic treatments are available for the management of hypertension, yet only about 50% of patients treated with antihypertensive medications have their blood pressure controlled. A key factor contributing to poor blood pressure control is suboptimal adherence to prescribed therapy. Despite numerous studies conducted over the last 50 years to identify the best method for increasing patient compliance, no single intervention has emerged as superior to the others. This article reviews the effectiveness of methods to improve antihypertensive medication adherence, discusses the effect of drug benefit caps on compliance, and proposes a framework for future clinical and research directions. RECENT FINDINGS Several recent systematic reviews and meta-analyses have attempted to quantify the effectiveness of various methods to improve adherence. As a result of the multiple factors influencing medication adherence, a patient-centered approach that tailors interventions aimed at overcoming barriers to adherence may be necessary. SUMMARY Physicians and other health care professionals should consider nonadherence to medication when evaluating a patient with poor blood pressure control. In selecting an intervention to improve compliance to medications, clinicians should consider engaging the patient in an intervention that overcomes patient-specific barriers. Future research should target development of adherence models, which simultaneously examine the effects and interactions of social, psychological, and biologic variables on antihypertensive medication adherence.

Abstract
PURPOSE OF REVIEW Patients' adherence to antihypertensive drug regimens is a complex but important factor in achieving blood pressure control and reducing adverse cardiovascular outcomes. Approximately one half of patients with hypertension adhere to prescribed medications, and fewer than one in three patients have controlled blood pressure. RECENT FINDINGS Several recent studies have highlighted the importance of patient medication adherence and have outlined factors that affect patient compliance with prescribed therapy. SUMMARY On the basis of published studies, a conceptual framework of factors that affect patient adherence is presented. Recognizing patient nonadherence to medical therapy as a factor leading to poor blood pressure control and adverse outcomes remains a key challenge for clinicians caring for patients with hypertension.

Abstract
SETTING Two health clinics in Los Angeles County, California. OBJECTIVE To identify factors associated with completion of care among foreign-born adolescents treated for latent tuberculosis infection (LTBI). DESIGN A total of 766 low-income adolescents (79% participation rate), including 610 foreign-born, were recruited. In prospective face-to-face interviews, data were obtained on socio-demographic and lifestyle characteristics, psychosocial factors and clinic-related variables. Medical chart data were abstracted regarding clinic appointment keeping and completion of treatment. Univariate and multivariate logistic regression analyses were performed to identify factors associated with completion of care. RESULTS Foreign-born adolescents were more likely to complete care than US-born adolescents, with 82% completion of care rate. In logistic regression analyses after controlling for age, medication taking behavior (OR 1.26, 95%CI 1.15-1.39), living with both parents (OR 1.74, 95%CI 1.02-2.97), sexual intercourse (OR 0.66, 95%CI 0.36-1.19) and speaking mostly or only English with parents (OR 0.39, 95%CI 0.15-1.03) were independently associated with completion of care. CONCLUSION These findings contribute to our understanding of the factors that may explain why some adolescents complete care whereas others do not. They provide supportive evidence that tailored intervention programs should be developed to support the screening and completion of treatment of foreign-born adolescents.

Abstract
Perceptions of health status among 331 homeless veterans and homeless nonveterans were examined. Homeless veterans were significantly less apt to perceive their health as fair/poor (8%) compared to non-veteran homeless men (19%). Homeless veterans were also more likely to report having a regular source of care (57% versus 36%). Logistic regression analysis indicated the adjusted odds of fair/poor health were more than two times greater for persons reporting depressive symptomatology than for those without this history; veterans continue to remain less likely to report fair/poor health than nonveterans. High rates of substance abuse were observed for the entire sample. Such differences in perceived health result in important health access issues.
