    INTRODUCTION: Antibiotic resistance is a rapidly emerging problem. A major concern is methicillin-resistant Staphylococcus aureus (MRSA), especially in developing countries where cost-effectiveness is imperative. Restriction of vancomycin usage is necessary to reduce the emergence of vancomycin-resistant organisms. The aim of this study was to look into the appropriate use of vancomycin based on the Healthcare Infection Control Practices Advisory Committee (HICPAC) guidelines and to investigate serum levels of vancomycin.
    METHODOLOGY: The study was performed retrospectively. Medical records of patients treated with vancomycin for the past year were identified and selected.
    RESULTS: Overall, 118 patients were treated with vancomycin. Appropriate use of vancomycin was significantly higher than inappropriate use (p = 0.001). Approximately 85% (n = 100) of patients were given vancomycin for treatment, whereas the rest were given it for prophylaxis. Appropriate use of vancomycin was observed in 67% (n = 79) of patients. However, there was still a high rate of inappropriate vancomycin use for prophylaxis and treatment (n = 39, 33.1%). The most common reason for inappropriate use was non-neutropenic and non-line related sepsis (n = 36, 30.8%). Therapeutic drug monitoring of vancomycin was performed in 79 patients (67%). Most patients (n = 53, 67%) demonstrated sub-therapeutic levels during the first measurement. There was no significant difference between trough levels achieved with a higher (> 15 mg/kg) versus a lower dose (< 15 mg/kg).
    CONCLUSIONS: This study demonstrates that there was still a high level of inappropriate vancomycin use, which could potentially contribute to vancomycin resistance.

    Background: The lack of price control in Malaysia has led to increased market competition, resulting in high medicine prices, notably in the private sector. This largely affects patients' out-of-pocket expenses in the private sector. Although generic medicines are preferred due to affordability, the prices are still notably high.

    Methods: This study compares innovator and generic medicine prices to estimate treatment affordability in the private sector. Private hospitals and community retail pharmacies were examined from 2011 to 2015. Data were collected on the basis of recommendations by the World Health Organization's Health Action International.

    Results: The markup of generic medicines was significantly higher than that of innovator medicines during the study period (p<0.001). While the markup of generic medicine was 31%-402% (36%-171% and 31%-402% for core and supplementary list items), that of innovator medicine was 24%-86% (28%-86% and 24%-80% for core and supplementary list items). There was no significant increase in the median price ratio for 11 selected generic medicines (from 1.8±3.9 to 2.9±8.2) (p>0.05). However, the median price ratio of the 11 innovator medicines significantly increased (from 4.9±6.1 to 11.2±20.3) (p=0.045). Affordability of all generic medicines was below the 2-day wage for treatment, with captopril (25 mg tablet) reporting the highest cost (1.1-1.7-day wages). Among innovator medicines, omeprazole (20 mg capsule; 6.2-7.0 days' wages) reported the highest median treatment cost.

    Conclusion: There is a need for policies to control national drug prices, to ensure medicine prices are monitored. This can help keep out-of-pocket expenses, especially in middle-income countries such as Malaysia, at a minimal in the private sector.

    Antibiotic resistance is a major problem globally. Awareness of the impact and significance of antibiotic resistance is a first step in hindering its progression. We conducted this survey to evaluate knowledge, attitudes and practices regarding antibiotic use in Malaysia. A total of 373 respondents were surveyed, 219 (58.1%) were female and 312 (83%) were Malay ethnicity. Eighty-four point two percent (314) had used antibiotics more than once (> 1) during the previous year. We found respondents who were less likely to take antibiotics (≤ 1) during the previous year were more likely to agree that antibiotic resistance was a serious public health issue compared to those that took antibiotic more than once during the previous year (p < 0.0001). A significantly greater number of patients (67.2%) who took antibiotics more than once during the previous year did not complete the full course than those who took antibiotics no more than once (55.9%) during the previous year (p < 0.01). We found the frequency of antibiotic use was related to knowledge about antibiotics among the study population. It is essential to develop educational interventions to correct the misuse and misunderstanding of antibiotics.

    Inappropriate initial antibiotics for pneumonia infection are usually linked to extended intensive care unit stay and are associated with an increased risk of mortality. This study evaluates the impact of inappropriate initial antibiotics on the length of intensive care unit stay, risk of mortality and the co-predictors that influences these outcomes. This retrospective study was conducted in an intensive care unit of a teaching hospital. The types of pneumonia investigated were hospital-acquired pneumonia and ventilator-associated pneumonia. Three different time points were defined as the initiation of appropriate antibiotics at 24 h, between 24 to 48 h and at more than 48 h after obtaining a culture. Patients had either hospital-acquired pneumonia (59.1%) or ventilator-associated pneumonia (40.9%). The length of intensive care unit stay ranged from 1 to 52 days (mean; 9.78±10.02 days). Patients who received appropriate antibiotic agent at 24 h had a significantly shorter length of intensive care unit stay (5.62 d, P<0.001). The co-predictors that contributed to an extended intensive care unit stay were the time of availability of susceptibility results and concomitant diseases, namely cancer and sepsis. The only predictor of intensive care unit death was cancer. The results support the need for early appropriate initial antibiotic therapy in hospital-acquired pneumonia and ventilator-associated pneumonia infections.

    Falls are a major problem among the elderly and can lead to serious injury. Adults older than 65 years suffer the greatest number of severe falls. This study aims to evaluate the knowledge and perception of medication related falls as well as preferred medication related fall prevention programs in the local population. A cross-sectional survey was conducted among the elderly patients in a tertiary hospital. A total of 86 patients (n=86) were interviewed. Approximately 23.3% (20 patients) of the elderly had a history of falls over the past 6 months. Majority of the elderly considered falls as a major concern (80 patients, 93%) and is preventable (55 patients, 64%). Patients with a medical condition reported a significantly greater number of falls within the past 6 months (p<0.001). Approximately 69% (59 patients) of the elderly were aware of their medication and associated risk of falls. In patients that were unaware of medication associated risk of falls, 81.5% (22 patients) had a potentially inappropriate medication preferred preventive interventions for medication related falls were related to strength and training programs (37 patients, 43%). The knowledge of falls, medication related falls and intervention strategies in the elderly were minimal.

    BACKGROUND: There is a steep increase in the consumer use of complementary alternative medicine (CAM), with many users unaware of the need to inform their health care providers. Various predictors including psychosocial factors such as beliefs and behavior have been accounted for preference toward CAM use, with varying results.
    METHODS: This study investigates the belief and attitude regarding preference toward CAM use among the Malaysian population by using a questionnaire-based, cross-sectional study.
    RESULTS: A large majority of the 1,009 respondents admitted to taking at least one type of CAM (n=730, 72.3%). Only 20 (1.9%) respondents were found to have negative beliefs (total score <35), 4 (0.4%) respondents had neutral beliefs (total score =35), and 985 (97.6%) respondents had positive belief toward CAM (total score >36). A total of 507 (50.2%) respondents were categorized as having a negative CAM attitude, while 502 (49.8%) respondents were categorized as having a positive CAM attitude. It was demonstrated that there was a positive correlation between belief and attitude score (ρ=0.409, P<0.001). Therefore, the higher the belief in CAM, the more positive the attitude was toward CAM. Those who were using CAM showed a stronger belief (P=0.002), with a more positive attitude (P<0.001) toward it, than those who were not using CAM.
    CONCLUSION: Identifying belief regarding preference toward CAM use among the public could potentially reveal those with a higher tendency to use CAM. This is important as not everyone feels the need to reveal the use of CAM to their health care providers, which could lead to serious repercussions such as interactions and adverse effects.

    AIMS/INTRODUCTION: The aim of the present study was to determine the status of glycemic control and identify factors associated with good glycemic control among diabetic patients treated at primary health clinics.

    MATERIALS AND METHODS: A systematic random sample of 557 patients was selected from seven clinics in the Hulu Langat District. Data were collected from patients' medication records, glycemic control tests and structured questionnaires. Logistic regression analysis was carried out to predict factors associated with good glycemic control.

    RESULTS: Variables associated with good glycemic control included age (odds ratio 1.033; 95% confidence interval 1.008-1.059) and duration of diabetes mellitus (odds ratio 0.948; 95% confidence interval 0.909-0.989). Compared with the patients who were receiving a combination of insulin and oral antidiabetics, those receiving monotherapy (odds ratio 4.797; 95% confidence interval 1.992-11.552) and a combination of oral antidiabetics (odds ratio 2.334; 95% confidence interval 1.018-5.353) were more likely to have good glycemic control. In the present study, the proportion of patients with good glycemic control was lower than that in other published studies. Older patients with a shorter duration of diabetes who were receiving monotherapy showed better glycemic control.

    CONCLUSIONS: Although self-management behavior did not appear to influence glycemic control, diabetic patients should be consistently advised to restrict sugar intake, exercise, stop smoking and adhere to medication instructions. Greater effort by healthcare providers in the primary health clinics is warranted to help a greater number of patients achieve good glycemic control.

    Diabetes mellitus is a growing global health problem that affects patients of all ages. Even though diabetes mellitus is recognized as a major chronic illness, adherence to antidiabetic medicines has often been found to be unsatisfactory. This study was conducted to assess adherence to medications and to identify factors that are associated with nonadherence in type 2 diabetes mellitus (T2DM) patients at Primary Health Clinics of the Ministry of Health in Malaysia.

    OBJECTIVES: Recent work with the yeast model revealed that the antiprotozoal drug quinine competes with tryptophan for uptake via a common transport protein, causing cellular tryptophan starvation. In the present work, it was hypothesized that similar interactions may occur in malaria patients receiving quinine therapy.

    PATIENTS AND METHODS: A direct observational study was conducted in which plasma levels of drug and amino acids (tryptophan, tyrosine and phenylalanine) were monitored during quinine treatment of malaria patients with Plasmodium falciparum infections.

    RESULTS: Consistent with competition for uptake from plasma into cells, plasma tryptophan and tyrosine levels increased ≥2-fold during quinine therapy. Plasma quinine levels in individual plasma samples were significantly and positively correlated with tryptophan and tyrosine in the same samples. Control studies indicated no effect on phenylalanine. Chloroquine treatment of Plasmodium vivax-infected patients did not affect plasma tryptophan or tyrosine. During quinine treatment, plasma tryptophan was significantly lower (and quinine significantly higher) in patients experiencing adverse drug reactions.

    CONCLUSIONS: Plasma quinine levels during therapy are related to patient tryptophan and tyrosine levels, and these interactions can determine patient responses to quinine. The study also highlights the potential for extrapolating insights directly from the yeast model to human malaria patients.

    BACKGROUND: A previous systematic review reported that increase in patients' medication cost-sharing reduced patients' adherence to medication. However, a study among patients with medication subsidies who received medication at no cost found that medication nonadherence was also high. To our knowledge, no study has evaluated the influence of different medication payment schemes on patients' medication adherence.
    OBJECTIVE: This study aims to review research reporting the influence of payment schemes and their association with patients' medication adherence behavior.
    METHODS: This study was conducted using systematic review of published articles. Relevant published articles were located through three electronic databases Medline, ProQuest Medical Library, and ScienceDirect since inception to February 2015. Included articles were then reviewed and summarized narratively.
    RESULTS: Of the total of 2,683 articles located, 21 were included in the final analysis. There were four types of medication payment schemes reported in the included studies: 1) out-of-pocket expenditure or copayments; 2) drug coverage or insurance benefit; 3) prescription cap; and 4) medication subsidies. Our review found that patients with "lower self-paying constraint" were more likely to adhere to their medication (adherence rate ranged between 28.5% and 94.3%). Surprisingly, the adherence rate among patients who received medication as fully subsidized was similar (rate between 34% and 84.6%) as that of other payment schemes. The studies that evaluated patients with fully subsidized payment scheme found that the medication adherence was poor among patients with nonsevere illness.
    CONCLUSION: Although medication adherence was improved with the reduction of cost-sharing such as lower copayment, higher drug coverage, and prescription cap, patients with full-medication subsidies payment scheme (received medication at no cost) were also found to have poor adherence to their medication. Future studies comparing factors that may influence patients' adherence to medication among patients who received medication subsidies should be done to develop strategies to overcome medication nonadherence.

    Anticoagulant responses to warfarin vary among patients, based on genetic factors, diet, concomitant medications, and disease state. We evaluated the effectiveness and safety of a 10mg warfarin initiation nomogram in an Asian population. Retrospective cross-sectional audit studies were conducted from March 2009 to March 2010. The use of a 10mg-loading dose to initiate warfarin treatment resulted in 33(84.6%) patients attaining a therapeutic INR within four days (mean time, 2.6 days). There was no significant correlation between age, gender, race, and serum albumin for the time to reach a therapeutic INR. A significant correlation was noted for patient's baseline INR and time to reach a therapeutic INR (P<0.05). No significant differences were observed in time to reach a therapeutic INR in patients treated with specific class of concomitant drugs or patients with specific disease states. The overall incidence of over-anticoagulation was 35.9%; however, no bleeding episodes were encountered. In conclusion, the use of a 10mg warfarin nomogram was effective in rapidly achieving a therapeutic INR. However, the nomogram's safety is debatable owing to the high over-anticoagulation rate warfarin-administered patients. Caution is recommended in the initiation of warfarin treatment using the 10mg nomogram.

    Background Shared decision-making is vital in achieving desired drug therapy goals, especially with antibiotics, in view of the potential long-term reduction in drug resistance. However, shared decision-making is rarely practiced with adolescent patients. Objectives The aim of the study was to identify the effect antibiotic education has on willingness to engage in shared decision-making among adolescents in Malaysia. Setting Participants from secondary schools in Malaysia were enrolled with ethical approval. Method The adolescents answered a validated questionnaire, which included demographics, antibiotic knowledge, attitude towards antibiotic use, and the Control Preference Scale, which measures willingness to engage in shared decision-making. Afterwards, antibiotic education was delivered to participating students. Main outcome measure Knowledge about and attitude toward antibiotics were investigated. Results A total of 510 adolescents participated in the study. Knowledge of antibiotics significantly increased post education (pre 3.2 ± 1.8 vs. post 6.8 ± 2.1, p

    Background: Limited efforts have been made to evaluate medication adherence among subsidized and self-paying patients.

    Objective: To investigate medication adherence among patients with and without medication subsidies and to identify factors that may influence patients' adherence to medication. Setting: Government healthcare institutions in Kuala Lumpur, Selangor, and Negeri Sembilan and private healthcare institutions in Selangor and Negeri Sembilan, Malaysia.

    Methods: This cross-sectional study sampled patients with and without medication subsidies (self-paying patients). Only one of the patient's medications was re-packed into Medication Event Monitoring Systems (MEMS) bottles, which were returned after four weeks. Adherence was defined as the dose regimen being executed as prescribed on 80% or more of the days. The factors that may influence patients' adherence were modelled using binary logistic regression. Main outcome measure: Percentage of medication adherence.

    Results: A total of 97 patients, 50 subsidized and 47 self-paying, were included in the study. Medication adherence was observed in 50% of the subsidized patients and 63.8% of the self-paying patients (χ2=1.887, df=1, p=0.219). None of the evaluated variables had a significant influence on patients' medication adherence, with the exception of attending drug counselling. Patients who attended drug counselling were found to be 3.3 times more likely to adhere to medication than those who did not (adjusted odds ratio of 3.29, 95% CI was 1.42 to 7.62, p = 0.006).

    Conclusion: There is no significant difference in terms of medication adherence between subsidized and self-paying patients. Future studies may wish to consider evaluating modifiable risk factors in the examination of non-adherence among subsidized and self-paying patients in Malaysia.

    Background: Preference for herbal use is increasing worldwide. This is especially true for Malay women in Malaysia that is steeped in traditional and cultural values and surrounded by diverse flora. However, concerns arise with the use of herbs due to the lack of monitoring, scientific evidence and risk of adverse effects. As such identifying potential herbal users is vital to ensure appropriate management is optimised.

    Objective: This study derives insights on preferred herbs, perception and predictors of herbal use for health among Malay women in Malaysia.

    Methods: This was a cross-sectional survey, comprising of Malay women, performed in all fourteen states in Malaysia. Respondents were assessed for demographic characteristic, current use of herbal medicine, their preferred herbal medicine and perception of herbal use. Predictors of herbal use were then determined using a multivariate logistic regression model.

    Results: A total of 1067 respondents were included in the study of which 592 (55.5%) admitted to using herbs for health. In general, raw herbs were the most preferred herbal remedies used (n=407, 69.5%). A significantly higher number of respondents perceived that herbal remedies would not cause any problems to women's overall health (n=725, 67.9%) (χ2=137.5, df(1), p<0.001), although a large majority agreed that not all remedies were safe for pregnant women (n=979, 91.8%) (χ2=744.03, df(1), p<0.001). Among predictors of herbal use were marital status and income (χ2=203.98, df(795) p<0.001). Those that were married were 3.9 times more likely to use herbs than unmarried women (p<0.001). Having an income of

    Eliminating the Plasmodium vivax malaria parasite infection remains challenging. One of the main problems is its capacity to form hypnozoites that potentially lead to recurrent infections. At present, primaquine is the only drug used for the management of hypnozoites. However, the effects of primaquine may differ from one individual to another. The aim of this work is to determine new measures to reduce P. vivax recurrence, through primaquine metabolism and host genetics. A genetic study of MAO-A, CYP2D6, CYP1A2 and CYP2C19 and their roles in primaquine metabolism was undertaken of healthy volunteers (n = 53). The elimination rate constant (Ke) and the metabolite-to-parent drug concentration ratio (Cm/Cp) were obtained to assess primaquine metabolism. Allelic and genotypic analysis showed that polymorphisms MAO-A (rs6323, 891G>T), CYP2D6 (rs1065852, 100C>T) and CYP2C19 (rs4244285, 19154G>A) significantly influenced primaquine metabolism. CYP1A2 (rs762551, -163C>A) did not influence primaquine metabolism. In haplotypic analysis, significant differences in Ke (p = 0.00) and Cm/Cp (p = 0.05) were observed between individuals with polymorphisms, GG-MAO-A (891G>T), CT-CYP2D6 (100C>T) and GG-CYP2C19 (19154G>A), and individuals with polymorphisms, TT-MAO-A (891G>T), TT-CYP2D6 (100C>T) and AA-CYP2C19 (19154G>A), as well as polymorphisms, GG-MAO-A (891G>T), TT-CYP2D6 (100C>T) and GA-CYP2C19 (19154G>A). Thus, individuals with CYP2D6 polymorphisms had slower primaquine metabolism activity. The potential significance of genetic roles in primaquine metabolism and exploration of these might help to further optimise the management of P. vivax infection.

    Background: Identifying knowledge gaps regarding antibiotic use and resistance is important for future interventional strategies. There is limited information on Malaysia's general public's knowledge and expectations on antibiotic use.

    Purpose: To assess the knowledge of antibiotic use and resistance, expectations from antibiotic prescription, and identify inappropriate practices related to antibiotic use among Malaysia's general public.

    Materials and Methods: A nationwide cross-sectional survey was conducted among Malaysians aged 18 years and above from each state, from May to November 2019. Participants were recruited via quota sampling, followed by convenient sampling. A validated self-administered questionnaire was used to collect data.

    Results: Of the 1971 respondents recruited, 56.6% had engaged in at least one inappropriate practice; particularly, not completing the antibiotic course (48.8%). The mean total knowledge score was 8.57±4.24 (total 20). The majority incorrectly believed that antibiotics work on viral infections (79.1%) and colds and coughs (77.0%). Less than half of them believed that antibiotics could be stopped when symptoms improved (42.8%). Most respondents incorrectly perceived that antibiotic resistance occurs when the body becomes resistant to antibiotics (90.2%) and antibiotic resistance is not an issue in the country (62.9%). More than half the participants expected antibiotics to be prescribed for self-limiting symptoms (fever: 62.9%, sore throat: 57.2%, cold or flu: 50.9%). Respondents with better knowledge were less likely to engage in inappropriate antibiotic use (never engaged: 9.26±4.40 versus had engaged: 8.11±4.00, p<0.001), and expect doctors to discuss with them the need for antibiotics (agree/strongly agree: 9.03±4.25 versus neutral: 6.62±3.91 versus disagree/strongly disagree: 8.29±4.00, p<0.001).

    Conclusion: Knowledge gaps in the role of antibiotics and understanding of antibiotic resistance should be considered whtpen designing future educational strategies for the general public.

    BACKGROUND: Recurrence rates of Plasmodium vivax infections differ across various geographic regions. Interestingly, South-East Asia and the Asia-Pacific region are documented to exhibit the most frequent recurrence incidences. Identifying patients at a higher risk for recurrences gives valuable information in strengthening the efforts to control P. vivax infections. The aim of the study was to develop a tool to identify P. vivax- infected patients that are at a higher risk of recurrence in Malaysia.

    METHODS: Patient data was obtained retrospectively through the Ministry of Health, Malaysia, from 2011 to 2016. Patients with incomplete data were excluded. A total of 2044 clinical P. vivax malaria cases treated with primaquine were included. Data collected were patient, disease, and treatment characteristics. Two-thirds of the cases (n = 1362) were used to develop a clinical risk score, while the remaining third (n = 682) was used for validation.

    RESULTS: Using multivariate analysis, age (p = 0.03), gametocyte sexual count (p = 0.04), indigenous transmission (p = 0.04), type of treatment (p = 0.12), and incomplete primaquine treatment (p = 0.14) were found to be predictors of recurrence after controlling for other confounding factors; these predictors were then used in developing the final model. The beta-coefficient values were used to develop a clinical scoring tool to predict possible recurrence. The total scores ranged between 0 and 8. A higher score indicated a higher risk for recurrence (odds ratio [OR]: 1.971; 95% confidence interval [CI]: 1.562-2.487; p ≤ 0.001). The area under the receiver operating characteristic (ROC) curve of the developed (n = 1362) and validated model (n = 682) was of good accuracy (ROC: 0.728, 95% CI: 0.670-0.785, p value

    INTRODUCTION: Tuberculosis (TB) treatment interruption remains a critical challenge leading to poor treatment outcomes. Two-thirds of global new TB cases are mostly contributed by Asian countries, prompting systematic analysis of predictors for treatment interruption due to the variable findings.

    METHODS: Articles published from 2012 to 2021 were searched through seven databases. Studies that established the relationship for risk factors of TB treatment interruption among adult Asian were included. Relevant articles were screened, extracted and appraised using Joanna Briggs Institute's checklists for cohort, case-control and cross-sectional study designs by three reviewers. Meta-analysis was performed using the random effect model in Review Manager software. The pooled prevalence and predictors of treatment interruption were expressed in ORs with 95% CIs; heterogeneity was assessed using the I2 statistic. The publication bias was visually inspected using the funnel plot.

    RESULTS: Fifty eligible studies (658 304 participants) from 17 Asian countries were included. The overall pooled prevalence of treatment interruption was 17% (95% CI 16% to 18%), the highest in Southern Asia (22% (95% CI 16% to 29%)), followed by Eastern Asia (18% (95% CI 16% to 20%)) and South East Asia (16% (95% CI 4% to 28%)). Seven predictors were identified to increase the risk of treatment interruption, namely, male gender (OR 1.38 (95% CI 1.26 to 1.51)), employment (OR 1.43 (95% CI 1.11 to 1.84)), alcohol intake (OR 2.24 (95% CI 1.58 to 3.18)), smoking (OR 2.74 (95% CI 1.98 to 3.78)), HIV-positive (OR 1.50 (95% CI 1.15 to 1.96)), adverse drug reactions (OR 2.01 (95% CI 1.20 to 3.34)) and previously treated cases (OR 1.77 (95% CI 1.39 to 2.26)). All predictors demonstrated substantial heterogeneity except employment and HIV status with no publication bias.

    CONCLUSION: The identification of predictors for TB treatment interruption enables strategised planning and collective intervention to be targeted at the high-risk groups to strengthen TB care and control in the Asia region.

    Adherence to antiretroviral therapy (ART) is essential in determining successful treatment of human immunodeficiency virus (HIV). The adoption of digital health is suggested to improve ART adherence among people living with HIV (PLHIV). This study aimed to systematically determine the effect of digital health in enhancing ART adherence among PLHIV from published studies. The systematic search was conducted on Scopus, Web of Science (WoS), PubMed, Ovid, EBSCOHost, and Google Scholar databases up to June 2022. Studies utilized any digital health as an intervention for ART adherence enhancement and ART adherence status as study's outcome was included. Digital health refers to the use of information and communication technologies to improve health. Quality assessment and data analysis were carried out using Review Manager (RevMan) version 5.4. A random-effects model computed the pooled odds ratio between intervention and control groups. The search produced a total of 1864 articles. Eleven articles were eligible for analysis. Digital health was used as follows: six studies used short message service or text message alone, three studies used mobile applications, and two studies used combination method. Four studies showed statistically significant impacts of digital health on ART adherence, while seven studies reported insignificant results. Results showed studies conducted using combination approach of digital health produced more promising outcome in ART adherence compared to single approach. New innovative in combination ways is required to address potential benefits of digital health in promoting ART adherence among PLHIV.
