Treatment non-adherence among methadone maintenance patients and associated factors: a multicenter, cross-sectional study in Vietnam.

OBJECTIVE: This multicenter, cross-sectional study was conducted to investigate the prevalence of treatment non-adherence and its associated factors among methadone maintenance patients in Vietnam. METHODS: This secondary data analysis was conducted using the data from a previous study. Six hundred patients were interviewed face-to-face to collect data on their demographic characteristics and social support. Information about the treatment characteristics and patients' non-adherence was gathered from medical records and books monitoring their treatment process. Treatment non-adherence was defined as missing at least one methadone dose in the last three months. RESULTS: The overall prevalence of non-adherence was 45.7%. The average social support score of patients who completely adhered to treatment was significantly higher than that of those who did not (p < 0.001). In the multivariate logistic regression model, for each one-unit increase in social support (one score), treatment time (a year), and patient's monthly income (one million Vietnam dongs), the odds of non-adherence decreased by 28% (aOR = 0.72, 95%CI 0.59-0.88, p = 0.002), 15% (aOR = 0.85, 95%CI 0.80-0.91, p < 0.001) and 9% (aOR = 0.91, 95%CI 0.85-0.97, p = 0.004), respectively. Patients living in Son La (a mountainous province) were 1.72 times (95%CI 1.09-2.71) more likely to be non-adherent as compared to those in other areas (p = 0.020). As per univariate analyses, other associated factors could be age, education level, family monthly income, occupation, and opioid relapse (p < 0.001). CONCLUSIONS: A high non-adherence rate was found among Vietnamese methadone maintenance patients. Interventions involving social support, occupation, income, and education are needed to improve their treatment adherence.

Antiretroviral therapy non-adherence and its association with psychosocial factors in Nigeria: comparative study of sexual minority and heterosexual men living with HIV.

Sexual minority men (gay, bisexual and other men who have sex with men; SMM) in Nigeria are disproportionately affected by HIV compared to heterosexual men. There is a dearth of research on the correlates of antiretroviral therapy (ART) non-adherence and correlates in both groups. The current study examined the associations of ART non-adherence with sociodemographic and psychosocial characteristics among a sample of Nigerian heterosexual and SMM. Between March and September 2014, we surveyed 120 SMM and 108 heterosexual men receiving ART in Lagos and Abuja, Nigeria. We specified univariate and multivariable linear regression models to examine correlates of ART non-adherence. We found that 50.8% and 29.6% of sexual minority and heterosexual men respectively self-reported ART non-adherence which was significantly associated with psychosocial factors such as stigma, depressive symptoms, and suicidality. Mental health care and psychosocial support should be incorporated into routine HIV care for Nigerian SMM living with HIV.

Medication non-adherence and its associated factors among kidney transplant patients in a large teaching hospital in Ethiopia.

BACKGROUND: This study examines medication adherence among kidney transplant patients at St. Paul's Hospital Millennium Medical College (SPHMMC) in Addis Ababa, Ethiopia, focusing on the level of adherence and associated factors to immunosuppressant medicines. METHODS AND MATERIALS: A cross-sectional study was conducted on 270 patients from October 2021 to January 2022 using a structured questionnaire analyzed with SPSS version 26. The prevalence of medication adherence was computed, and a binary logistic regression was fitted to estimate the association. Medication adherence level measurement in post-kidney transplant patients was assessed using the Simplified Medication Adherence Questionnaire (SMAQ) and Basel Adherence Assessment Scale in Immunosuppressants (BAASIS). A 95% confidence interval and p-value < 0.05 were used for statistical significance. RESULTS: The study found that 71.5% of kidney transplant patients were male, with a median age of 37 and a mean duration of 3.55 years. Medication adherence in post-kidney transplant patients was 81.9%. Post-transplant duration above 5 years and missing follow-up visits more than two times was associated with a 92.6% and 91.2% in medication non-adherence rate respectively. Additionally, forgetfulness was associated with a 90.6%, non-adherence level compared to drug unavailability and financial reasons. CONCLUSION AND RECOMMENDATION: The study indicates that our patients exhibit higher medication adherence than WHO-measured levels, suggesting the need for healthcare providers to strengthen their intervention, especially for those above 5 years post-kidney transplant. The reason for increased adherence could be explained by the health education program about the medication name, dosing, frequency of ingestion and adverse effects of the drug, and effects of non-adherence.

Factors Associated with Non-Adherence to Self-Management Among Patients with Chronic Obstructive Pulmonary Disease: A Survey Using the Delphi Technique and Analytic Hierarchy Process.

Background: The relevant factors and patterns of non-adherence to self-management among patients with chronic obstructive pulmonary disease (COPD) need to be elucidated to improve self-management. Purpose: This study was a survey to prioritize the relevance of factors associated with non-adherence to COPD self-management using the Delphi technique and analytic hierarchy process (AHP). Patients and Methods: A total of 15 expert panels were established to determine the priority of relevant factors in a three-round Delphi survey and an AHP. To develop the preliminary conceptual framework for non-adherence to COPD self-management, findings from a systematic literature review, a qualitative study using in-depth interviews with COPD patients, and the first round of the Delphi survey were integrated. Based on the preliminary framework, the content validity ratio (CVR) was analyzed to examine the consensus among expert panels in the second and third rounds of the Delphi survey, and the relative weight was determined by pairwise comparisons between alternative factors in the AHP. Results: In developing the preliminary conceptual framework, 8 factor categories and 53 factors were identified as relevant to non-adherence to COPD self-management. Of the 53 factors, 22 factors with a CVR of 0.49 or higher were identified in the Delphi survey. A total of 14 of the 53 factors were common to both the Delphi survey and AHP with high weights. The most notable factors were prolonged treatment, experience of treatment failure, and unknown effects of medication. Conclusion: Through consensus decision-making by experts, 14 factors were identified as relevant factors associated with non-adherence to COPD self-management. A hierarchical and systematic framework incorporating factors associated with non-adherence to COPD self-management was developed in this study. Further research is needed to develop intervention strategies based on factors associated with non-adherence to COPD self-management.

Effect of Drug Monitoring on Adherence and Blood Pressure: A Multicenter Randomized Clinical Trial.

BACKGROUND: Drug concentration in blood or urine is an acknowledged method to detect non-adherence. Observational studies suggest that informing patients about low or absent serum drug levels improves blood pressure (BP). We performed a multicenter randomized clinical trial to test the hypothesis that therapeutic drug monitoring (TDM) could improve drug adherence and BP in patients with uncontrolled hypertension and reduced adherence to antihypertensive drugs. METHODS: Patients were ≥18 years on stable treatment with at least two antihypertensive agents. We planned to randomize 80 non-adherent patients with a systolic daytime ambulatory BP (ABPM) ≥135 mmHg to TDM-intervention or not. The control group and the study-personnel who measured BP remained uninformed about serum drug measurements throughout. All patients and physicians were blinded for BPs. Lifestyle advice and detailed information on disease process and importance of BP treatment were given to both groups. RESULTS: From 2017 to 2022, we randomized 46 diagnosed non-adherent from a total of 606 patients with uncontrolled hypertension. The TDM-group had a 6.7 (±14.5) mmHg reduction from 147.9 (±10.3) to 141.1 (±14.1) mmHg, and the control group experienced a 7.3 (±13.2) mmHg reduction from 147.1 (±9.2) to 139.1 (±17.4) mmHg, p=0.9 between groups. Adherence improved in both groups, 73% in the TDM group and 59% in the control group became adherent at three months, p=0.51. CONCLUSIONS: In our prospective multicenter clinical trial of uncontrolled and non-adherent hypertensive patients, we found no additional effect of therapeutic drug monitoring (TDM) on blood pressure and drug adherence compared with standard care.

Acute kidney injury in lamotrigine-induced DRESS syndrome.

We present a case of lamotrigine-triggered DRESS (drug reaction with eosinophilia and systemic symptoms) syndrome with acute kidney injury stage 3. A 17-year-old girl with known epilepsy treated with lamotrigine presented with acute kidney injury as well as skin eruption, fever, and apathy. Extended diagnostics, considering infectious and autoimmune diseases, remained unremarkable. Lamotrigine blood levels were within the target range. Kidney biopsy showed acute interstitial nephritis with tubular necrosis. Methylprednisolone pulse therapy led to an improvement in kidney function; skin eruption and neurological symptoms resolved. During the hospital stay, the girl admitted to inconsistent and variable intake of lamotrigine, occasionally resulting in notable overdosing. This report demonstrates that acute kidney injury in lamotrigine-induced DRESS syndrome is an acute interstitial nephritis with tubular necrosis, an aspect that has not been deeply characterized so far. Additionally, we aim to elevate awareness towards non-adherence as cause of disease, especially among the adolescent population.

Non-adherence to Anti-diabetic Prescriptions Among Type 2 Diabetes Mellitus Patients in the Kurdistan Region of Iraq.

BACKGROUND: Treatment adherence is a primary key in controlling diabetes disease. The study aims to determine the prevalence of treatment adherence in type 2 diabetes mellitus (T2DM) patients, investigate the potential influence of adherence on elevated blood glucose levels, and identify the key factors which play a role in non-adherence to the prescribed drugs. METHOD: A cross-sectional study method was utilized to collect data from all T2DM patients at the Diabetic and Endocrine Centre and Shar Hospital in Sulaymaniyah city in the Kurdistan region of Iraq from February 2022 to April 2022. The data collection was performed through a structured questionnaire. The prevalence of drug adherence was assessed using the Morisky Medication-Taking Adherence Scale (4-item), and the glycated hemoglobin test (A1C) was used to determine the blood glucose level. RESULT: A total of 300 participants were studied, and more than half of them (192; 64%) revealed that they did not adhere to their anti-diabetic medications. Non-adherence was significantly associated with higher A1C. Several barriers to non-adherence were identified as multiple medications, feeling the dose given is high, lack of finance, and side effects by 209 (70%), 116 (39%), 113 (38%), and 103 (34%), respectively. CONCLUSION: The current study's result revealed that most T2DM patients have no adherence to their medication. This non-adherence is significantly linked to higher A1C levels, emphasizing the critical role of medication compliance in managing diabetes effectively. The study also sheds light on the multiple barriers such as taking multiple prescriptions, the perception that the dose is excessive, lack of finances, and experiencing side effects, which contribute to non-adherence among diabetes patients. These findings underscore the need for healthcare providers to address these barriers and develop tailored strategies to enhance medication adherence among individuals with diabetes.

Non-adherence and non-persistence with antiretroviral treatment in Belgium: A real-world evaluation using a pharmacy database, 2018-2021.

PURPOSE: To evaluate the real-world rates of non-adherence and non-persistence to antiretroviral therapy (ART) among treatment-naïve adult patients with HIV after a 12-month follow-up period in Belgium. METHODS: A retrospective analysis of longitudinal pharmacy claims was conducted using the Pharmanet database from January 1, 2018, to December 31, 2021. Non-adherence was assessed over 12 months and reported as the proportion of days covered below the 80% threshold. Non-persistence was defined as the first 90-day gap in treatment between the two types of ART dispensed. Poisson regression with robust standard error and Cox proportional hazard models were used to assess the factors associated with non-adherence and non-persistence, respectively. RESULTS: Overall, 2999 patients were initiated on ART between 2018 and 2021. After a 12-month follow-up, the proportions of non-adherence and non-persistence were 35.6% and 15.9%, respectively in 2018, and decreased to 18.7% and 6.8%, respectively in 2021. Non-adherence was higher among women, Brussels residents, and those receiving multiple-tablet regimens (MTRs). Similarly, the prevalence of non-persistence was higher among women and MTR recipients. CONCLUSION: Among treatment-naïve adults with HIV in Belgium, non-adherence, and non-persistence to ART showed improvement over the study period but remained at high levels. Disparities were observed by sex and between geographical regions. Prioritizing strategies targeting women in Brussels and facilitating the transition from MTRs to single-tablet regimens should be emphasized optimize adherence to ART in Belgium.

Adherence in Atopic Dermatitis.

Atopic dermatitis is a chronic dermatologic condition requiring extended treatment times with topical application of medications. While atopic dermatitis treatments can be highly effective when used as directed, oftentimes patients do not respond as expected, raising concern for nonadherence versus nonresponse. This chapter aims to describe what is currently known about adherence in atopic dermatitis and to discuss strategies to improve adherence in order to improve treatment outcomes. Whether intentional or unintentional, nonadherence to treatment can limit patient outcomes of this disease for a variety of reasons. These include frustration with medication efficacy, inconvenience, and fear of side effects. Other factors include forgetfulness, financial burden of treatment, lack of trust in the physician, dislike of prescribed medication, or lack of understanding of disease or treatment. Several interventions have been studied with the aim of improving adherence in atopic dermatitis-such as educational workshops for patients and caregivers, earlier follow-up visits, and text messages reminders-however, these are often limited by sample size and power. Further research is needed to study both specific patterns of nonadherence in atopic dermatitis, as well as methods to improve them.

Risk Factors for Non-Adherence to Medication for Liver Transplant Patients: An Umbrella Review.

Background/Objectives: Liver Transplantation (LT) is the second most common solid organ transplantation. Medication adherence on LT patients is key to avoiding graft failure, mortality, and important quality of life losses. The aim of this study is to identify risk-factors for non-adherence to treatment of liver transplant patients according to reliable published evidence. Methods: An umbrella review within the context of adherence to immunosuppressant medication of LT patients, was conducted. The review was performed in accordance with the principles of the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines. Results: A total of 11 articles were finally included for the review. Non-adherence factors were identified and allocated using the WHO classification of factors for non-adherence. Each of these groups contains a subset of factors that have been shown to influence adherence to medication, directly or indirectly, according to literature findings. Conclusions: The results of the review indicate that sociodemographic factors, factors related to the patient, factors related to the treatment, condition-related and health system-related factors are good categories of predictors for both adherence and non-adherence to immunosuppressive medication in LT patients. This list of factors may help physicians in the treating and recognizing of patients with a potential risk of non-adherence and it could help in the designing of new tools to better understand non-adherence after LT and targeted interventions to promote adherence of LT patients.

Mid-term results of "off-label" use of the Endurant stentgraft in patients with infrarenal abdominal aortic aneurysms.

OBJECTIVES: EVAR is the preferred treatment modality for patients with an infrarenal abdominal aortic aneurysm with suitable anatomy. Each manufacturer of aortic stentgrafts has specific anatomic requirements. In some patients, it is not possible to adhere to the instructions for use, but alternative treatment is also not possible. In these patients, EVAR can be performed outside instructions for use. METHODS: In this study, all consecutive patients in whom an Endurant II or IIS stentgraft was used between 1 January and 31 December were reviewed. We compared the two patient groups in whom this stentgrafts was used outside and inside instructions for use. Patients with planned adjuvant therapy, for example, chimney procedure or iliac side branches, were excluded. RESULTS: In 74 of 178 (41.6%) patients, the instructions for use were not adhered. The main reason was pathology of the aortic neck. There were more patients with type IA endoleak, this difference was borderline significant (p = .06). There were more patients with limb occlusion in the early postoperative period, but at the end of the follow-up period, the incidence was comparable. Aneurysm-related mortality and all-cause mortality were comparable in both groups. CONCLUSION: In this study, real-life experience with the Endurant II and IIS stentgraft is described. Non-adherence with instructions for use was associated with a higher risk of endoleak type IA (p = .06). In the early postoperative period, there were more patients with limb occlusion; this finding was not observed anymore at the end of the follow-up period.

Limited significance of bicarbonate therapy in the treatment of diabetic ketoacidosis: a rare case report in the periphery of Nepal.

Introduction and importance: An uncontrolled hyperglycaemia accompanied by metabolic acidosis and an increase in total body ketone, if left untreated, has the potential to develop into complications, including diabetes ketoacidosis (DKA). Management of this complication with IV hydration, IV Insulin, and potassium (KCL) maintenance is a comprehensive approach. On the contrary, bicarbonate therapy is generally not regarded as a standard treatment due to its unfavourable outcome. Case presentation: The authors present a case of a 21-year-old female who was brought in a semiconscious state to the emergency department with complaints of pain in the abdomen, headache, and vomiting. DKA was diagnosed following the patient's symptoms and arterial blood gas analysis report. She was managed with IV fluids, IV insulin, and KCL. Clinical discussion: Generally, pH less than 6.8 has a poor patient survival outcome. Here, the patient presented with pH less than 6.6, where she was managed with the standard regimen without the need to administer bicarbonate therapy. Conclusion: DKA is a life-threatening condition that can be precipitated by non-adherence to medications and infections with IV insulin and hydration playing a pivotal role in its management while bicarbonate offers no beneficial effect.

Non-adherence to anti-tuberculosis treatment and associated factors among TB patients in public health facilities of Hossana town, Southern Ethiopia, 2022.

Background: Non-adherence to anti-tuberculosis treatment is one of the crucial challenges to improving TB treatment outcomes and reducing healthcare costs. The prevalence of non-adherence to anti-tuberculosis treatment is not well documented in the study context. Therefore, this study was aimed at estimating the prevalence of non-adherence to anti-tuberculosis treatment and associated factors among TB patients attending TB clinics in Hosanna town, Southern Ethiopia, in 2022. Methods: An institution-based cross-sectional study was conducted from April to May 2022. A systematic random sampling technique was employed to select a sample of 233 study subjects from all four public health facilities. According to the order of arrival, every second person was interviewed. Data were collected using a structured questionnaire that was created using several works of literature. A multivariable binary logistic regression analysis was used to identify factors associated with non-adherence to anti-TB drugs. The adjusted odds ratio (AOR) with a 95% confidence interval (CI) was estimated. Results: The study included 233 tuberculosis (TB) patients with a response rate of 100%. The prevalence of non-adherence was 18% (95% CI: 15.39, 21.82). Being in the continuation phase (AOR = 3.09, 95% CI: 1.16, 8.23), not attending formal education (AOR = 2.47, 95% CI: 1.12, 5.42), not disclosing TB status to their family (AOR = 2.36, 95% CI: 0.11, 5.04) and having poor TB knowledge (AOR = 3.09, 95% CI: 1.48, 6.48) were significantly associated with non-adherence to TB treatment. Conclusion: Among TB patients, there was a significant prevalence of non-adherence to anti-TB medications. Interventions that target patients with low education status, are in the continuation phase, and do not disclose their TB status to their families are required to improve TB treatment adherence. In addition, improving health education is important to enhance TB knowledge, which has an impact on TB treatment adherence. The need for good drug adherence should be emphasized while counseling TB patients.

Treatment Non-adherence Patterns Among Patients With Mental Illness: A Study From the District Mental Health Care Center in India.

INTRODUCTION: The success of any medical intervention, including mental health treatment, depends largely on patient adherence to the prescribed regimen. In psychiatric illnesses, one of the biggest problems is getting people to adhere to their treatment schedule, representing a treatment gap that increases the burdens of patients, families, communities, and countries. Globally, it has become necessary for community health organizations to actively work towards reducing this gap and treatment non-adherence. Therefore, in this study, we aimed to examine treatment non-adherence patterns among patients with mental illness. MATERIALS AND METHODS: This work used a retrospective study design and consecutive sampling. The data source was secondary data obtained from the healthcare records of patients registered in the outpatient department of the District Mental Health Care Center, India, from January 2022 to December 2022. RESULTS: Out of a total of 883 patients recruited for the study, 35.7% (n=315) were on regular follow-up over a duration of more than one year. Among patients with severe mental illness, 46% (n=46) had regular follow-ups and were compliant with therapy. About 49% of patients (n=433) discontinued their treatment after the initial contact with the therapist, with the highest rate among those with substance use disorders (77.0%; n=57). The remaining 15.3% (n=135) of recruited patients discontinued their follow-up appointments over a duration of 1 week to 12 months. Overall, 64.3% (n=568) of the recruited patients discontinued their treatment within one year. CONCLUSION: There was considerable early treatment dropout among patients with mental illness. However, this treatment discontinuation can be avoided because the individual identities of these patients are well-known to the therapist or facility, as they have had at least one interaction with the therapist. In order to improve treatment adherence, patients with mental illnesses must receive consistent support through community outreach programs, home visits, and new strategies to promote treatment compliance.

Iron folic acid supplementation adherence level and its associated factors among pregnant women in Ethiopia: a multilevel complex data analysis of 2019 Ethiopian mini demographic and health survey data.

Background: Iron and folic acid deficiency is a worldwide public health concern, particularly in low and middle-income countries. In Ethiopia, adherence to iron and folic acid supplements is still very low. Despite the fact that a number of studies on IFA supplementation have been conducted in Ethiopia, they do not indicate a nationwide problem and do not use advanced models to demonstrate clustering effects. The purpose of this study was to assess the level of non-adherence to iron folic acid supplementation and predictors among pregnant women in Ethiopia. Objective: To assess iron folic acid supplementation adherence level and its associated factors among pregnant women in Ethiopia using data from the 2019 Mini-Ethiopian demographic health survey. Methods: The Mini Ethiopian Demographic and Health Survey 2019 data were obtained from the official database website of the Demographic and Health Survey program (http://dhsprogram.com). The analysis included a sample of 2,356 weighted study participants. A multivariable multilevel mixed-effects logistic regression model was used Variables with p-values less than 5%) was reported as statistically significant variables in the multivariable analysis. Results: The proportion of mothers who did not adhere to iron and folic acid supplements was 81.03% (95 %CI, 79.39, and 82.56). Birth interval less than 2 years [AOR: 2.03; 95% CI: 1.12, 3.66], women ever born less than six children [AOR: 1.99; 95% CI: 1.09, 3.64], starting ANC visit during first trimester [AOR: 2.74; 95 %CI: 1.03, 7.30], region [AOR = 0.24; 95% CI: 0.10], and having a high no ANC visit in the community [AOR = 1.77; 95% CI: 1.08, 2.88] were statistically significant factors. There was Intra-Custer Correlation (ICC = 17.72%), indicating that 17.72% variability in non-adherence levels was due to clusters. Conclusion and recommendation: In Ethiopia, nearly four out of every five pregnant women did not receive iron folic acid supplementation for the recommended periods. Birth intervals, number of children, timing of ANC visits, region, and community level no ANC service were significant factors for non-adherence IFAS. As a result, the community, govern metal and non-governmental sectors enacting on health should focus on reducing non-adherence through tailored interventions on factors that influence it.

Medication non-adherence and predictor factors among adult asthmatic patients in Ethiopia: a systematic review and meta-analysis.

OBJECTIVE: A pronounced burden is evident in individuals with asthma, with approximately half of them not adhering to their prescribed medication. Therefore, this study aimed to assess the pooled prevalence of anti-asthma medications non-adherence in Ethiopia. DATA SOURCES: A comprehensive search was conducted across multiple electronic databases including PubMed, Africa Index Medicus, Science Direct, Hinari, and a search engine, Google Scholar from October 5 to 20, 2023. In addition, digital research repositories from Addis Ababa and Bahir Dar University were accessed. DATA SELECTION: The eligibility criteria was employed to screen studies after uploading search results to EndNote software to remove duplicates first. Then, two investigators, CT and BBT, independently assessed titles, abstracts, and the full text of all retrieved references to identify potentially eligible studies. RESULT: This meta-analysis, which was conducted in Ethiopia, and included 11 full-text articles, revealed a pooled asthma medication non-adherence level of 51.20% (95% CI 35.20%, 67.20%) with substantial heterogeneity (I2 = 99.08%). The review has also identified factors predicting non-adherence among asthmatic patients: free (health service) (AOR: 0.31, 95% CI 0.18-0.54), poor knowledge (AOR: 2.85, 95% CI 1.61-5.05), absence of formal education (AOR: 3.01, 95% CI 1.72-5.25), history of previous ADR (AOR: 8.57, 95% CI 1.12-65.3), and the presence of Co- morbidity(AOR: 3.28, 95% CI 2.014-5.68), had shown association with asthma medication non-adherence. CONCLUSION: Asthma medication non-adherence is notably high in Ethiopia. Addressing medication non-adherence requires a comprehensive approach, including clear communication between healthcare providers, patient education, and addressing financial barriers to ensure better adherence in asthma patients.

Treatment satisfaction with disease-modifying therapy is the only predictor of Adherence among multiple sclerosis patients from Upper Egypt.

Despite the proven efficacy of the disease-modifying therapy (DMT) for multiple sclerosis (MS), the rates of non-adherence are frequently high. We aimed to evaluate the rate of non-adherence to the first DMT in Upper Egypt and identify different contributing factors. Out of 310 patients, ninety-seven adult patients with RRMS were recruited from three MS units located in Upper Egypt and were subjected to the following: complete clinical history, expanded disability status score (EDSS), Eight-item Morisky Medication Adherence Scale (MMAS-8), abbreviated Treatment Satisfaction Questionnaire for Medication-9 (TSQM-9), Hamilton depression scale, Fatigue Severity Scale (FSS) and the Pittsburgh Sleep Quality Index (PSQI). According to MMAS-8 scores, 63 (64.9%) of patients were non-adherent to their first DMT. Non-adherent patients are more likely to have longer disease duration (p = 0.002), longer duration on first DMT (p = 0.030), first DMT-start date before 2019 (p = 0.040), and lower treatment satisfaction scores (p = 0.016). However, there was no significant relation with physical disability, depression, fatigue, or sleep quality. On the regression analysis model, a lower treatment satisfaction score was the only predictor of DMT non-adherence (p = 0.012). Despite expanding DMT options, non-adherence among MS patients in Upper Egypt is high. Treatment satisfaction with DMT is the only predictor of adherence among MS patients of Upper Egypt. Adherence and satisfaction with the prescribed DMT should be assessed carefully to maximize DMT benefits.

Predictors, mortality, and health outcomes of intensive phase non-adherence to a regimen in patients with drug-susceptible tuberculosis: a nationwide linkage database.

OBJECTIVES: The clinical importance of adhering to the regimen in tuberculosis patients has been widely investigated, but most studies were conducted in controlled settings and in limited populations. We aimed to measure the level of real-world adherence during intensive phase and investigate the predictors and the risk of mortality and health outcomes of intensive phase non-adherence in tuberculosis patients. STUDY DESIGN: We conducted a nationwide cohort study by linking the Korean National Tuberculosis Surveillance System and the National Health Information Database. METHODS: We included all incident drug-susceptible tuberculosis patients who initiated the regimens recommended by the World Health Organization from 2013 to 2018. Adherence was measured using the proportion of days covered (poor [<50%], moderate [50%-79%], and high [≥80%]). We used logistic regression model to assess predictors and the Cox proportional hazard model to evaluate the risk of mortality and health outcomes with intensive phase non-adherence. RESULTS: Of 46,818 patients, there were 8% and 11% with poor and moderate adherent groups, respectively. Age ≥45 years, insulin use, and history of renal failure were predictors of non-adherence. Compared with high adherent group, poor and moderate adherent groups were associated with a substantial risk of mortality (poor: hazard ratio, 2.14 [95% confidence interval, 1.95-2.34]; moderate: 1.76 [1.62-1.92]). Similar trends were observed for health outcomes. Stratified analyses showed a higher risk of mortality in patients with medical aid, low income, and history of renal failure, systematic corticosteroids, and immunomodulators. CONCLUSIONS: Non-adherence during intensive phase increased mortality risk by twofold, underscoring targeted intervention for high-risk population, including advanced diabetes, and immunocompromised patients.

Medium-term exposure to size-fractioned particulate matter and asthma exacerbations in China: A longitudinal study of asthmatics with poor medication adherence.

BACKGROUND: Studies have shown that short- and long-term exposure to particulate matter (PM) can increase the risk of asthma morbidity and mortality. However, the effect of medium-term exposure remains unknown. We aim to examine the effect of medium-term exposure to size-fractioned PM on asthma exacerbations among asthmatics with poor medication adherence. METHODS: We conducted a longitudinal study in China based on the National Mobile Asthma Management System Project that specifically and routinely followed asthma exacerbations in asthmatics with poor medication adherence from April 2017 to May 2019. High-resolution satellite remote-sensing data were used to estimate each participant's medium-term exposure (on average 90 days) to size-fractioned PM (PM1, PM2.5, and PM10) based on the residential address and the date of the follow-up when asthma exacerbations (e.g., hospitalizations and emergency room visits) occurred or the end of the follow-up. The Cox proportional hazards model was employed to examine the hazard ratio of asthma exacerbations associated with each PM after controlling for sex, age, BMI, education level, geographic region, and temperature. RESULTS: Modelling results revealed nonlinear exposure-response associations of asthma exacerbations with medium-term exposure to PM1, PM2.5, and PM10. Specifically, for emergency room visits, we found an increased hazard ratio for PM1 above 22.8 µg/m3 (1.060, 95 % CI: 1.025-1.096, per 1 µg/m3 increase), PM2.5 above 38.2 µg/m3 (1.032, 95 % CI: 1.010-1.054), and PM10 above 78.6 µg/m3 (1.019, 95 % CI: 1.006-1.032). For hospitalizations, we also found an increased hazard ratio for PM1 above 20.3 µg/m3 (1.055, 95 % CI: 1.001-1.111) and PM2.5 above 39.2 µg/m3 (1.038, 95 % CI: 1.003-1.074). Furthermore, the effects of PM were greater for a longer exposure window (90-180 days) and among participants with a high BMI. CONCLUSION: This study suggests that medium-term exposure to PM is associated with an increased risk of asthma exacerbations in asthmatics with poor medication adherence, with a higher risk from smaller PM.
