    BACKGROUND: This study aimed to assess the most common physical side effects experienced by local chemotherapy patients. Their perceptions of these side effects and informational needs from clinical pharmacists were also evaluated.

    MATERIALS AND METHODS: This was a single-center, cross-sectional study. A face-to-face interview guided by a structured questionnaire with cancer patients admitted to receive repeated cycles of chemotherapy was conducted. Information collected included chemotherapy-related side effects after last chemotherapy experience, the most worrisome side effects, the side effects overlooked by healthcare professionals and the preferred method, amount and source of receiving related information.

    RESULTS: Of 99 patients recruited, 90 participated in this survey (response rate: 90.9%). The majority were in the age range of 45-64 years (73.3%) and female (93.3%). Seventy-five (83.3%) and seventy-one (78.9%) experienced nausea and vomiting, respectively. Both symptoms were selected as two of the most worrisome side effects (16.7% vs. 33.3%). Other common and worrisome side effects were hair loss and loss of appetite. Symptoms caused by peripheral neuropathies were perceived as the major symptoms being overlooked (6.7%). Most patients demanded information about side effects (60.0%) and they would like to receive as much information as possible (86.7%). Oral conversation (83.3%) remained as the preferred method and the clinical pharmacist was preferred by 46.7% of patients as the educator in this aspect.

    CONCLUSIONS: The high prevalence of chemotherapy-related side effects among local patients is of concern. Findings of their perceptions and informational needs may serve as a valuable guide for clinical pharmacists to help in side effect management in Malaysia.

    BACKGROUND: Inability to read instructions on drug labels has been identified among the Malaysian population since 1990's.
    OBJECTIVE: To assess the impact of font-enlarged and pictogram-incorporated labels used for long-term medications on patients' adherence, comprehension and preferences.
    SETTING: Outpatient pharmacy in one of the major general hospitals across Northern Malaysia.
    METHOD: This was a three-arm, randomized controlled trial. Outpatients with refill prescriptions of selected oral antihypertensive or antidiabetic medications were screened for eligibility. They were randomly allocated with standard (n = 35), font-enlarged (n = 40) or pictogram-incorporated (n = 35) labels. Assessment of baseline adherence scores using the 8-item Morisky Medication Adherence Scale, comprehension scores using a structured questionnaire and preferences was conducted upon recruitment. Follow-up telephone interviews were conducted after 4 weeks.
    MAIN OUTCOME MEASURE: The changes of patients' adherence and comprehension scores and their preferences.
    RESULTS: Within-group comparisons demonstrated an increase of total adherence scores after 4 weeks in all three groups (mean changes 0.35, 0.58 and 0.67; p = 0.029, 0.013 and 0.011, respectively). The repeatedly measured total comprehension score of pictogram-incorporated label group was significantly higher than baseline (mean change 0.37, p = 0.010). Two intervention groups obtained significantly higher scores for few items in both adherence and comprehension measurements after 4 weeks as compared with baselines. As indicated by F tests, three groups did not significantly differ in the changes of both total adherence and comprehension scores (p = 0.573 and 0.069, respectively) with the subjects' age adjusted. Elderlies and those with a higher number of morbidity preferred pictogram-incorporated label over font-enlarged label.
    CONCLUSION: We did not find a significant change of both adherence and comprehension levels after the introduction of modified medication labels. However, on the basis of within-group comparisons, they may have positive influences on certain aspects of patients' adherence and comprehension. Variations in preferences may reflect the unique need of different subgroups in receiving written medication instructions.

    Background: Apart from reducing occupational exposure to cytotoxic hazards, the PhaSeal® closed-system transfer device (CSTD) can extend the beyond-use dates (BUDs) of unfinished vials of antineoplastic drugs for up to 168 hours (seven days). In this study, the total material cost incurred by its use in a Malaysian government-funded hospital was calculated. Methods: A list of vial stability following initial needle punctures of 29 commonly-used antineoplastic drugs was compiled. The amount of the materials used, including drugs, infusion bottles, the PhaSeal® CSTD and other consumables, was recorded on a daily basis for three months in 2015. The total cost was calculated based on the actual acquisition costs, and was compared with that of a hypothetical scenario, whereby conventional syringe-needle sets were used for the same amounts of preparations. Results: The use of the PhaSeal® CSTD incurred a cost of MYR 383,634.52 (USD 92,072.28) in three months, representing an average of MYR 170.5 (USD 40.92) per preparation or an estimated annual cost of MYR 1,534,538.08 (USD 368,289.14). Compared with conventional syringe-needle approach, it is estimated to lead to an additional spending of MYR 148,627.68 (USD 35,670.64) yearly. Conclusion: Although there was a reduction of drug wastage achieved by extending BUDs of unfinished vials using the PhaSeal® CSTD, cost saving was not observed, likely attributable to the wide use of lower-priced generic drugs in Malaysia. Future studies should further evaluate the possibility of cost saving, especially in health settings where branded and high-cost antineoplastic drugs are more commonly used.

    Background: In Malaysia, the treatment for chronic myeloid leukemia (CML) has long been delivered under the
    Malaysian Patient Assistance Program (MYPAP), but research on identifying factors contributing to non-adherence to
    tyrosine kinase inhibitors (TKIs) is still limited. The current study explored understanding and challenges of Malaysian
    CML patients in taking imatinib and nilotinib. Methods: Semi-structured, face-to-face interviews were conducted
    with 13 CML patients receiving treatment at a public tertiary care center, and were analyzed using the content analysis
    approach. Results: The patients generally demonstrated inadequate knowledge, particularly of the natural history and
    staging of CML, the function of TKIs, and the methods used for monitoring the effectiveness of treatment. A number of
    them also had experiences of withholding, skipping or altering the treatment, mainly due to the life-disturbing adverse
    drug effects (ADRs), forgetfulness, and religious and social issues. Besides, most of them were found having limited
    skills in managing the ADRs, and not using prompts as reminders to take the medications. Furthermore, even though
    nilotinib was generally perceived as better tolerated as compared with imatinib, the inconvenience caused by the need
    to take it twice daily and on an empty stomach was constantly highlighted by the patients. Conclusion: While TKIs
    are widely used for CML treatment in Malaysia, the findings have revealed a lack of patient education and awareness,
    which warrants an integrated plan to reinforce medication adherence.

    WHAT IS KNOWN AND OBJECTIVE: It has been reported that more than 80% of out-of-hospital medication errors among the young children involve liquid formulations. The usefulness of pictorial aids to improve communication of medication instructions has not been extensively investigated for child health. The objective of this study was to determine the effectiveness of pictorial aids used to assist caregivers in the administration of liquid medications.
    METHODS: MEDLINE, CINAHL, PsycINFO, ScienceDirect, Scopus and the Cochrane Library were searched for articles published up to February 2015. Studies that used pictorial aids with liquid medications and measured at least one of the following outcomes were included: dosing accuracy, comprehension of medication instructions, recall of information and adherence of caregivers. Two authors independently selected studies, extracted data and assessed methodological quality of studies using the Cochrane Collaboration's tool.
    RESULTS AND DISCUSSION: Five experimental studies (four hospital based and one community based) with a total of 962 participants were included. A wide range of liquid formulations were studied, including both prescription and over-the-counter medications. The existing findings suggest that pictographic interventions reduced dosing errors, enhanced comprehension and recall of medication instructions and improved adherence of caregivers. Incorporating pictorial aids into verbal medication counselling or text-based instructions was more beneficial than using the single approach alone. Mixed results were identified for the relationship between health literacy of caregivers and effectiveness of pictorial aids.
    WHAT IS NEW AND CONCLUSION: The evidence remains limited due to the small number of studies found and variations in methodological quality. This review suggests that pictorial aids might be potential interventions, but more high-quality studies are needed to support the routine use of any pictogram-based materials with liquid medications in the clinical settings.

    INTRODUCTION: The objective of this retrospective study was to evaluate the effectiveness and safety of acupuncture-assisted anesthesia (AAA) in breast lump excision.

    METHODS: The medical records of all patients who underwent breast lump excision under AAA in combination with electrical stimulation at traditional acupuncture points in 2016 were examined. All of them (n = 17) received electrostimulation (2-4 Hz) using single needles inserted at bilateral LI4 and PC6. They also underwent insertion of four acupuncture needles at the lump site, which were electrically stimulated at 30 Hz frequency.

    RESULTS: All surgical procedures were successful with minimal use of analgesics and local anesthetic. The median pain score reported was 1/10 (interquartile range (IQR) = 2/10) at the first hour, and slightly increased to 2/10 (IQR = 2/10) between 24 and 48 h of the surgery. No major postoperative adverse events were documented, except for drowsiness in one case.

    CONCLUSION: AAA was found to be generally safe and effective for anaesthesia and analgesia in breast lump excision. However, a large-scale randomized controlled study is required to verify the findings.

    Introduction: Medication errors are more likely to occur in chronically ill children, who are highly dependent on caregivers for medication administration. This study aimed to explore the issues related to medication safety among pediatric outpatients in Malaysia from the caregivers' perspective. Methods: This was a qualitative study conducted between May and June 2018 at a pediatric clinic of a regional referral hospital. Caregivers of children who (1) were under 6 years of age and (2) had hypothyroidism, epilepsy, thalassemia, asthma, or other chronic diseases were recruited via purposive sampling. Each selected disease was represented by at least 3 caregivers, who were identified from the medical records of their children. Face-to-face interviews were conducted with each of them, facilitated by a semi-structured interview guide. All the interviews were audio-recorded, transcribed verbatim, and analyzed using the thematic analysis approach. Results: A total of 15 mothers with a median age of 34 years were interviewed. Three themes emerged from the interviews: (I) actual experiences with medication errors, (II) underlying risk factors for medication errors, and (III) recommendations to improve medication safety. Several cases of administration errors, including missed doses and self-decided dose adjustment, were detected. Furthermore, the caregivers were found to have inadequate understanding of the medications in general. Conclusions: While children were shown to be consistently exposed to medication errors at home in Malaysia, the recommendations of the caregivers, including the use of written instructions and a diary, could be effective strategies to improve the out-of-hospital medication safety in children.

    BACKGROUND: Pain remains common in people living with advanced cancer and is often inadequately managed. This study was designed to assess knowledge, perceptions and barriers to morphine use in cancer pain management among doctors in Malaysia.

    METHODS: Doctors from multiple disciplines in a general hospital were invited to complete a 39-item self-reported questionnaire between November 2020 and December 2020. Each question was based on a 5-point Likert scale (1 = strongly disagree; 5 = strongly agree). 'Agree' and 'strongly agree' were considered correct or positive responses, except for nine questions worded in the opposite direction. Associations between variables were confirmed using Pearson's chi-squared and Fisher's exact tests.

    RESULTS: Most respondents were house officers (206/321; 64.2%) with less than two years of service, followed by medical officers (68/321; 21.2%) and specialists (47/321; 14.6%). Only 7.2% of the respondents had received formal palliative care training before the study. Of the respondents, 73.5% were aware of the World Health Organization (WHO) analgaesic ladder, 60.7% were correct on oral morphine as the first line for moderate to severe cancer pain treatment and 91.9% knew the need to add rescue morphine for breakthrough pain. Additionally, 34.0% (P < 0.001) perceived morphine use caused addiction, 57.9% (n = 186) expressed fear of respiratory depression and 18.3% of medical officers and specialists perceived limited access and a maximum dose to prescribe. There was a significant difference in knowledge and perception between junior doctors and senior clinicians. The majority strongly agreed and agreed that there were inadequate training opportunities in cancer pain management.

    CONCLUSION: Inconsistent knowledge and negative perceptions of cancer pain management among doctors were demonstrated in this study.

    OBJECTIVES: To explore the perceived motivators, training supports and challenges to career advancement among fully and provisionally registered pharmacists (FRPs and PRPs) in the Malaysian public service.

    METHODS: Nine hundred and fifty-three pharmacists in the public service of Perak State, Malaysia, were invited for participation in an online survey that was conducted in October 2018. Based on a 5-point Likert scale, they were required to respond to 56 items, ranging from the perceived availability and importance of both motivators and training supports, the challenges to career advancement, to the awareness of the need for career planning. Their responses were subsequently dichotomized into 'agree'/'important' and 'disagree'/'not important'.

    KEY FINDINGS: Four hundred and eighty pharmacists participated in the survey, yielding a response rate of 51.2%. More than half of them agreed with the inflexibility of working time and the absence of a performance-based salary and promotion scheme. More than 80% of them also highly valued the training in both pharmacy-related areas and management. Apart from inadequate training, no specialization in pharmacy as a profession and the absence of a performance-based promotion scheme were identified as the major challenges to their career advancement. As compared with the PRPs, the FRPs had greater concern over the absence of a performance-based salary and promotion scheme, flexible working time and periodic feedback for their work performance.

    CONCLUSIONS: The findings indicate the inadequacy of the current system in providing recognition, training, feedback for work performance and a clear career pathway to pharmacists in the Malaysian public service, which warrants a change.

    INTRODUCTION: While Kedah has recorded the highest prevalence of diabetes among all the states in Malaysia, the information on the practice and effectiveness of disease management in public health institutions remains limited. This study aimed to evaluate the management and glycemic control of patients with type-2 diabetes mellitus (T2DM) at the primary care level in Kedah.

    METHODS: All T2DM patients, who made at least one visit to any of the 58 public health clinics in Kedah during August 2016 and July 2017, were included in this study. The sample was selected from the National Diabetes Registry using the stratified random sampling method. The information on the demographic and clinical characteristics, laboratory findings and pharmacological treatment was gathered from medical records of patients. The differences in mean HbA1C levels across subgroups of each variable were tested using the general linear model. The evaluation of the appropriateness of treatment was performed based on the recommendations of the latest Clinical Practice Guidelines for T2DM.

    RESULTS: The patients (n = 23,557) were mainly female (63.4%), of Malay ethnicity (80.1%) and middle-aged (62.2%), with a mean duration of T2DM of 6.2±7.16 years. Only 15.6% of them had a HbA1C level <6.5%, and 28.6% did not have their HbA1C levels tested over the 12-month period. Yet, the underutilization of combination treatment (≥2 antidiabetic agents) and insulin in the patients with a poor glycemic control was evident. Retinopathy emerged as the most prevalent diabetes-related complication (12.6%). Along with those with a longer duration of T2DM, the patients who were younger, female and of Indian ethnicity were found to generally have a poorer glycemic control.

    CONCLUSION: This study discloses the suboptimal T2DM management at the primary care level in Kedah, which warrants a statewide plan for improvement.

    Purpose: This study was conducted to determine the direct medical cost of treating melioidosis patients. The calculation was made according to the variables extracted from medical records.

    Materials and Methods: Data collection was performed retrospectively on a total of 293 cases from Hospital Sultanah Bahiyah, Kedah, Malaysia. The data consisted of personal information, treatment history, and investigation findings, including blood results, USG abdomen results, and CT scan results. The site of culture and sensitivity were also obtained. The total direct medical cost was based on the antibiotics/treatments received by the patients, diagnostic test and investigations performed. The trend analysis used to see the pattern of costs from 2014 to 2017. All the costs were compared based on patients' status and duration of stay at the hospital using the independent t-test.

    Results: The overall mean of direct medical cost for melioidosis amounted to US $233.61 (RM931.33). Overall, the finding confirms a huge reduction (44.7%) of direct medical cost from 2014 to 2017 (P = 0.001). From 2015 to 2016, there was a 19.1% reduction of direct medical cost (P>0.95), followed by a 38.8% reduction in costs from 2016 to 2017 (P = 0.019). In the case of the duration of stay, the mean of total direct medical cost among patients with ≥14 duration of stay was higher compared to those with <14 duration of stay (p < 0.001). There was no significant mean difference of direct medical cost between patients who were cured and died.

    Conclusion: Despite the higher mortality of melioidosis cases compared to other infectious diseases, there is a limitation in the amount of published data on the management cost of melioidosis. The importance of cost in managing this disease should be underlined to perform a fully prepared management toward the disease.

    Rifapentine is an anti-tuberculosis (anti-TB) drug with a prolonged half-life, but oral delivery results in low concentrations in the lungs because of its high binding (98%) to plasma proteins. We have shown that inhalation of crystalline rifapentine overcomes the limitations of oral delivery by significantly enhancing and prolonging the drug concentration in the lungs. The delivery of crystalline particles to the lungs may promote inflammation. This in vivo study characterizes the inflammatory response caused by pulmonary deposition of the rifapentine particles. The rifapentine powder was delivered to BALB/c mice by intratracheal insufflation at a dose of 20 mg/kg. The inflammatory response in the lungs and bronchoalveolar lavage (BAL) was examined at 12 h, 24 h, and 7 days post-treatment by flow cytometry and histopathology. At 12 and 24 h post-treatment, there was a significant influx of neutrophils into the lungs, and this returned to normal by day 7. A significant recruitment of macrophages occurred in the BAL at 24 h. Consistent with these findings, histopathological analysis demonstrated pulmonary vascular congestion and significant macrophage recruitment at 12 and 24 h post-treatment. In conclusion, the pulmonary delivery of crystalline rifapentine caused a transient neutrophil-associated inflammatory response in the lungs that resolved over 7 days. This observation may limit pulmonary delivery of rifapentine to once a week at a dose of 20 mg/kg or less. The effectiveness of weekly dosing with inhalable rifapentine will be assessed in murine Mycobacterium tuberculosis infection.

    INTRODUCTION: The immunochemical fecal occult blood test (iFOBT) has been widely used for opportunistic colorectal cancer (CRC) screening in average-risk individuals seeking care from public health clinics in Malaysia. This study provides a 5-year outcome evaluation of such a practice.

    METHODS: The findings for a few outcome indicators, ranging from the iFOBT uptake to the CRC and polyp detection rates, were generated from the data contributed by 583 public health clinics between 2014 and 2018. The trends in their changes were also evaluated.

    RESULTS: The iFOBT uptake constantly increased over the years (p < 0.001), totaling 2.29 % (n = 127,957) as at 2018. Nearly 10 % (n = 11,872) of the individuals screened had a positive test result. Of those who underwent colonoscopy (n = 6,491), 4.04 % (n = 262) and 13.93 % (n = 904) were found to have CRC and polyps, respectively.

    CONCLUSION: An uptrend in the CRC screening uptake was witnessed following the introduction of the iFOBT in public health clinics.

    Drug-related problems (DRPs) in the elderly include polypharmacy, potentially inappropriate medications, nonadherence, and drug-related falls. In this systematic review and meta-analysis, the prevalence of DRPs and complementary and alternative medicine (CAM) use among the Malaysian elderly was estimated. PubMed, Scopus, Web of Science, and Google Scholar databases were searched to identify studies published since their inception up to 24 August 2020. A random-effects model was used to generate the pooled prevalence of DRPs along with its corresponding 95% confidence interval (CI). The heterogeneity of the results was estimated using the I2 statistics, and Cochran's Q test and sensitivity analyses were performed to confirm the robustness of the results. We identified 526 studies, 23 of which were included in the meta-analysis. (n = 29,342). The pooled prevalence of DRPs among Malaysian elderly was as follows: (1) polypharmacy: 49.5% [95% CI: 20.5-78.6], (2) potentially inappropriate medications: 28.9% [95% CI: 25.4-32.3], (3) nonadherence to medications: 60.6% [95% CI: 50.2-70.9], and (4) medication-related falls 39.3% [95% CI: 0.0-80.8]. Approximately one in two Malaysian elderly used CAM. The prevalence of polypharmacy and potentially inappropriate medications among the Malaysian elderly population was high, calling for measures and evidence-based guidelines to ensure the safe medication use.

    BACKGROUND: Diabetes Mellitus (DM) is characterized by hyperglycemia (high blood glucose levels) which is due to the destruction of insulin-producing β-cells in the islets of Langerhans in the pancreas. It is associated with oxidative and endoplasmic reticulum stress. The plant alkaloid Palmatine has been previously reported to possess antidiabetic and antioxidant properties as well as other protective properties against kidney and liver tissue damage.

    OBJECTIVE: Here, we investigated the ability of Palmatine to reduce the up-regulation of chaperone proteins Glucose Regulatory Protein 78 (GRP78), and Calreticulin (CALR) protein in a Streptozotocin (STZ)-induced diabetic rat model.

    METHODS: Streptozotocin (STZ) induced diabetes in Sprague Dawley rats treated with 2mg/kg of Palmatine for 12 weeks after the elevation of plasma glucose levels above 11mmol/L post-STZ administration. Proteins were extracted from the pancreas after treatment and Two-Dimensional gel electrophoresis (2-DE), PDQuest 2-D analysis software genomic solutions and mass spectrometer were used to analyze differentially expressed protein. Mass Spectrometry (MS/MS), Multidimensional Protein Identification Technology (MudPIT) was used for protein identification.

    RESULTS: There was an up-regulation of the expression of chaperone proteins CALR and GRP78 and down-regulation of the expression of antioxidant and protection proteins peroxidoxin 4 (Prdx4), protein disulfide isomerase (PDIA2/3), Glutathione-S-Transferase (GSTs), and Serum Albumin (ALB) in non-diabetic rats. Palmatine treatment down-regulated the expression of chaperone proteins CALR and GRP78 and up-regulated the expression of Prdx4, PDIA2/3, GST, and ALB.

    CONCLUSION: Palmatine may have activated antioxidant proteins, which protected the cells against reactive oxygen species and endoplasmic stress. The result is in consonance with our previous report on Palmatine.

    BACKGROUND: While the world witnesses an increasing trend of young-onset colorectal cancer (CRC), the information regarding the impact of age on CRC is limited in Malaysia. This study aimed to compare the incidence, clinic-demographic profiles and survival rates of CRC between patients above and under 50 years of age in northern Malaysia.

    METHODS: This was a registry-based, cross-sectional study. All the CRC cases reported by 18 hospitals to the National Cancer Patient Registry - Colorectal Cancer (NCPR-CC) between January 2007 and December 2017 were included in the analysis. The patients were categorized by age into the above-50 and under-50 groups. The changes in the age-standardized incidence and mortality rates of both the age groups were determined using the time-series analysis, and the impact of age on the mortality risk was assessed using the Cox regression analysis.

    RESULTS: Of the 6,172 CRC patients enrolled in the NCPR-CC, 893 (14.5%) were in the under-50 group. As compared with their older counterparts, the patients in the under-50 group were more likely to be female, be of Malay ethnicity, be non-smokers, have a family history of CRC, and present late for treatment. The age-standardized incidence and mortality rates of CRC in the under-50 group remained stable over the years, while a decreasing trend was clearly seen in the mortality rates of CRC in the above-50 group (p=0.003). Nevertheless, the two age groups also did not differ in the mortality risk (adjusted hazards ratio: 1.10; 95% CI: 0.90, 1.36).

    CONCLUSION: Young-onset CRC constituted a considerable proportion of CRC cases in Malaysia. However, in contrast with the findings of most studies, it demonstrated neither an uptrend in age-standardized incidence rates nor a higher mortality risk. Our findings suggest the need to upscale and lower the recommended age for CRC screening in Malaysia.

    BACKGROUND: Caregivers' knowledge, practice and adherence in medication administration who care for children with chronic illness requiring long-term pharmacological treatments are factors associating with children medication safety at home. This study aimed to determine the medication-related knowledge, administration practice and adherence among caregivers of chronically ill children in Malaysia. This cross-sectional study was conducted at the paediatric outpatient clinic of a tertiary public hospital. Caregivers of chronically ill children, who engaged in medication administration at home for at least 3 months, were conveniently recruited. Their medication-related knowledge and administration practice were evaluated based on a checklist, while their adherence to medication administration was assessed using a validated 5-point scale. The associated factors were also explored.

    RESULTS: Of the 141 participants, most were mothers (90.8%) and had a full-time job (55.3%). Most of them had adequate medication-related knowledge (71.6%) and an appropriate administration practice (83.0%). The majority of them (83.0%) also rated themselves as adherent to medication administration. The participants with a child above 5 years of age (91.2%) were found to have a better practice than those with younger children (75.3%) in medication administration (p = 0.012). However, those with a child taking two (adjusted OR: 12.53) or three (adjusted OR: 8.29) medications, getting their refills from private health institutions apart from this hospital (adjusted OR = 7.06) and having multiple illnesses (adjusted OR = 21.25) were more likely to be not adherent to medication administration.

    CONCLUSION: Caregivers of chronically ill children in Malaysia generally have sufficient knowledge and an appropriate practice of medication administration at home. Yet, strategies to improve the adherence to medication administration, particularly in those who care for children with complicated health conditions, are warranted.

    Background: To discuss a range of strategic options for China to improve the accessibility of direct antiviral agents (DAAs) as the treatment for hepatitis C. Methods: We adopted a narrative review approach for comprehensive comparisons and in-depth analyses of the country context, and barriers of increasing the DAA treatment rate of hepatitis C in Malaysia and China, and how the two countries have been navigating the hepatitis C agenda. Findings: Malaysia adopted a series of successful strategies to scale up the diagnosis of hepatitis C and DAA treatment, which have valuable implications for China. Interpretation: The potential game-changing strategies for China to adapt from Malaysian experiences range from the stepping-up of political commitment and leadership, enhanced market competition, simplified and decentralized treatment at the strengthened primary care level, integrated healthcare services, coordinated government initiatives, to multi-organizational participation and civil society's active role in raising public awareness, and training of non-specialist physicians. Embarking on scale-up of hepatitis C treatment marks another contribution of China to improve the health of not only the Chinese citizens but also mankind, which is an important component for building healthy Chinese and global communities. Funding: No funding supported this study.
