RESUMEN
This real-world retrospective cohort study using Australian Pharmaceutical Benefits Scheme (PBS) 10% investigated changes in chronic lymphocytic leukemia (CLL) treatment by line of therapy, time-to-next-treatment, treatment duration, and overall survival (OS). Overall, 803 patients received their first PBS-reimbursed CLL medication between 1 January 2011 to 31 July 2021 (median age: 70 years; 64.6% male), 289 post-1 August 2020. In 2011, most first-line (1 L) prescribing was fludarabine, cyclophosphamide, and rituximab (FCR). By 2021, common 1L were chlorambucil ± CD20 (26.1%), Bruton Tyrosine Kinase inhibitor (BTKi) (26.1%), and CD20 monotherapy (23.9%). In 2011, relapsed/refractory (R/R) CLL treatment was CD20 monotherapy or FCR. By 2021, BTKi (57.7%) and venetoclax ± CD20 (26.1%) were most common. Compared to FCR, 1 L treatment duration (Hazard Ratio) was shorter for CD20 monotherapy (1.7) or chlorambucil ± CD20 (2.5). In R/R CLL, median duration was 24 (ibrutinib) and 19 months (venetoclax). Median OS was 127 months. CLLtreatment pattern shave greatly changed in Australia since the introduction of novel therapies.
RESUMEN
Understanding consequences of poor chelation compliance is crucial given the enormous burden of post-transfusional iron overload complications. We systematically reviewed iron-chelation therapy (ICT) compliance, and the relationship between compliance with health outcome and health-related quality of life (HRQoL) in thalassaemia patients. Several reviewers performed systematic search strategy of literature through PubMed, Scopus, and EBSCOhost. The preferred reporting items of systematic reviews and meta-analyses (PRISMA) guidelines were followed. Of 4917 studies, 20 publications were included. The ICT compliance rate ranges from 20.93 to 75.3%. It also varied per agent, ranging from 48.84 to 85.1% for desferioxamine, 87.2-92.2% for deferiprone and 90-100% for deferasirox. Majority of studies (N = 10/11, 90.91%) demonstrated significantly negative correlation between compliance and serum ferritin, while numerous studies revealed poor ICT compliance linked with increased risk of liver disease (N = 4/7, 57.14%) and cardiac disease (N = 6/8, 75%), endocrinologic morbidity (N = 4/5, 90%), and lower HRQoL (N = 4/6, 66.67%). Inadequate compliance to ICT therapy is common. Higher compliance is correlated with lower serum ferritin, lower risk of complications, and higher HRQoL. These findings should be interpreted with caution given the few numbers of evidence.

RESUMEN
This study evaluated the financial impact of increasing denosumab usage for managing postmenopausal osteoporosis over a 5-year period from the Malaysian healthcare provider's perspective. A gradual moderate increase in denosumab uptake would have a minimal budget impact, with potential savings in fracture treatment expenses. Optimizing denosumab usage could be a cost-effective and potentially affordable strategy to alleviate the economic burden of osteoporosis in Malaysia. PURPOSE: The study aimed to evaluate the budget impact of increasing the uptake of denosumab for the management of postmenopausal osteoporosis in Malaysia. METHODS: A Markov budget impact model was developed to estimate the financial impact of osteoporosis treatment. We modelled a scenario in which the uptake of denosumab would increase each year compared with a static scenario. A 5-year time horizon from the perspective of a Malaysian MOH healthcare provider was used. Model inputs were based on Malaysian sources where available. Sensitivity analyses were performed to examine the robustness of the modelled results. RESULTS: An increase in denosumab uptake of 8% per year over a 5-year time horizon would result in an additional budget impact, from MYR 0.26 million (USD 0.06 million) in the first year to MYR 3.25 million (USD 0.78 million) in the fifth year. When expressed as cost per-member-per-month (PMPM), these were less than MYR 0.01 across all five years of treatment. In sensitivity analyses, the acquisition cost of denosumab and medication persistence had the largest impact on the budget. CONCLUSION: From the perspective of a Malaysian MOH healthcare provider, moderately increasing uptake of denosumab would have a minimal additional budget impact, partially offset by savings in fracture treatment costs. Increasing the use of denosumab appears affordable to reduce the economic burden of osteoporosis in Malaysia.

AIM: To assess the economic burden of different chemotherapies for lung cancer patients and influencing factors in China. MATERIALS AND METHODS: The economic burden of lung cancer, including direct, indirect and intangible costs was measured within three months after diagnosis and treatment. Direct cost included the cost of hospitalization, outpatient visits, out-of-pocket drug purchases, costs of transportation, accommodation and meal expenses while seeking treatments in hospitals. Cost information was attained from questionnaire and patients' medical record. Indirect cost was measured by the patients' and their caregivers' productive days lost due to outpatient visits and hospitalization for lung cancer treatment. Intangible cost was obtained through the willingness-to-pay method from a questionnaire completed by the patient. RESULTS: Among the total cost of CNY71,401.92, direct cost, indirect cost and intangible cost constituted 89.02%, 4.29%, and 6.69% respectively. Educational level, occupation, family income, lung cancer classification, and the city of residence significantly influenced the total cost. LIMITATIONS: Limitations in our study included: First, our follow-up period of three months was relatively short compared to the whole survival period of lung cancer patients. Second, the sample size of the chemotherapy combined with targeted therapy group was not large enough, and the cost data obtained would need confirmation in future studies. Third, participants came from only two localities, which may somewhat limit the representativeness of the study results for the whole of China. CONCLUSIONS: The economic burden of lung cancer treatment mainly came from the cost of the drugs. Patients taking chemotherapy had significantly higher cost compared to patients using targeted therapy. The cost was generally higher for those with higher educational level, those with higher family income, and those living in an economically more developed city. Patients with NSCLC had higher cost compared to patients with SCLC.
In China, lung cancer is the leading cause of cancer-related deaths and imparts a heavy economic burden. Most lung cancer patients are treated with chemotherapeutic and/of targeted agents because they are usually diagnosed at an advanced stage (IIIB or IV). The use of targeted therapy has achieved high response rates, longer overall survival, and longer progression-free survival compared with conventional chemotherapies. Adverse reactions with targeted therapeutic agents are usually mild compared with conventional chemotherapy. However, targeted drugs for lung cancer are usually more expensive than conventional chemotherapeutic drugs. It should be noted that the adverse effects and toxicities caused by chemotherapeutic drugs are generally more serious compared to targeted drugs; therefore, a number of measures are needed to prevent or relieve these reactions clinically. This can increase the financial burden of lung cancer treatment. Does these two treatments have a different cost? Our results showed that educational level, occupation, family income, classification of lung cancer, and the city of residence significantly influenced the total cost. Patients taking chemotherapy had significantly higher cost compared to patients using targeted therapy. This result suggests that targeted therapy for lung cancer is a better choice than chemotherapy.

Introduction: Thalassemia is among the most common genetic disorders globally and many patients suffer from iron overload (IOL) complications that mainly affect the heart, liver and endocrine system. These events may be further complicated by drug-related problems (DRP), an inherent issue among patients with chronic diseases. Objective: The study aimed to evaluate the burden, associated factors and impacts of DRP in transfusion-dependent thalassemia (TDT) patients. Method: Eligible TDT patients under follow-up in a tertiary hospital between 01 March 2020 to 30 April 2021 were interviewed and their medical records were reviewed retrospectively to identify any DRP. DRPs were classified using the Pharmaceutical Care Network Europe (PCNE) classification version 9.1. The incidence and preventability of DRP were assessed and the associated risk factors were estimated by univariate and multivariate logistic regression. Results: A total of 200 patients were enrolled with a median (interquartile range: IQR) age of 28 years at enrolment. Approximately 1 in 2 patients were observed to suffer from thalassemia-related complications. Throughout the study period, 308 DRPs were identified among 150 (75%) participants, with a median DRP per participant of 2.0 (IQR 1.0-3.0). Of the three DRP dimensions, treatment effectiveness was the most common DRP (55.8%) followed by treatment safety (39.6%) and other DRP (4.6%). The median serum ferritin level was statistically higher in patients with DRP compared with patients without DRP (3833.02 vs. 1104.98 µg/L, p < 0.001). Three risk factors were found to be significantly associated with the presence of DRP. Patients with frequent blood transfusion, moderate to high Medication Complexity Index (MRCI) and of Malay ethnicity were associated with higher odds of having a DRP (AOR 4.09, 95% CI: 1.83, 9.15; AOR 4.50, 95% CI: 1.89, 10.75; and AOR 3.26, 95% CI: 1.43, 7.43, respectively). Conclusion: The prevalence of DRP was relatively high amongst TDT patients. Increased medication complexity, more severe form of the disease and Malay patients were more likely to experience DRP. Hence, more viable interventions targeted to these groups of patients should be undertaken to mitigate the risk of DRP and achieve better treatment outcomes.
RESUMEN
BACKGROUND: After the inclusion of more high-cost orphan drugs in China's National Reimbursement Drugs List, this study investigated issues relating to patient access to the 7 medicines for 4 rare diseases after listing. METHODS: This study collected data from a national survey conducted in China. Three aspects associated with the accessibility of medicines, namely, approachability, availability, and affordability, were analyzed using descriptive statistics. In addition, multilevel logistic regression models were used to investigate the associations between patient characteristics and the accessibility of surveyed orphan drugs. RESULTS: Of the 999 completed responses included in the study, 15% of the patients (n = 150) did not use the medicines because of non-medicine-related issues. Among the 849 patients using the surveyed medications, 64.4% (n = 547) encountered the problem of unavailability, whereas 51.2% (n = 435) reported affordability as an issue, and 49.6% (n = 320) had health expenditure beyond the catastrophic threshold. The data also indicated that Commercial Medical Insurance helped patients to relieve the cost burden on orphan drugs, but the payout of Commercial Medical Insurance failed to influence patients' decisions to continue the treatments. CONCLUSION: Accessibility of orphan drugs has improved in China after their inclusion in the National Reimbursement Drugs List. Nevertheless, the availability and affordability of medicines remained the barriers for patients to access the desired treatments. It is recommended that further policy refinement in conjunction with the collaboration among healthcare stakeholders is required to deliver better care for patients with rare disease.

WHAT IS KNOWN AND OBJECTIVE: Unintentional medication discrepancies (UMDs) are common in geriatric patients during care transitions, resulting in frequent undesirable consequences. Medication reconciliation could be a useful practice to prevent or ameliorate UMD. However, this practice in Vietnamese hospitals has not been well established or standardized. This study aims to determine the effect of pharmacist-initiated educational interventions on improving medication reconciliation practice. METHODS: This prospective 6-month pre-and post-study was conducted in two internal medicine wards in a Vietnamese 800-bed public hospital. Pharmacists provided training and short-term support to physicians on medication reconciliation. Primary outcome measures were the proportions of patients with at least one UMD at admission. Secondary outcome measures were the proportions of patients with preventable adverse drug events (pADEs) score ≥0.1 due to these UMDs. Odds ratio and 95% confidence intervals were assessed based on a multivariate logistic regression model. RESULTS AND DISCUSSION: One hundred fifty-two patients were recruited in the pre-intervention phase, and 146 in the post-intervention phase. Following the intervention, the proportion of geriatric patients with ≥1 UMD at admission significantly decreased from 55.3 to 25.3 % (ORadj 0.255, 95% CI: 0.151-0.431). Similarly, the proportion of patients with a pADE ≥0.1 at admission reduced from 44.1 to 11.6% [ORadj 0.188, 95% CI: 0.105-0.340] post-intervention. WHAT IS NEW AND CONCLUSION: Our pharmacist-initiated educational interventions have demonstrated the ability to produce substantial improvement in medication reconciliation practice, reducing UMDs and potential harm. Our approach may provide an alternate option to implement medication reconciliation for jurisdictions with limited healthcare resources.

Purpose: Geriatric inpatients generally have a high risk of drug-related problems (DRP) in prescribing following hospital admission, which are likely to cause negative clinical consequences. This is particularly evident in developing countries such as Vietnam. Therefore, clinical pharmacy service (CPS) aims to identify and resolve these DRPs to improve the quality use of medicines in the older population following hospital admission. Patients and Methods: The study was conducted as a prospective, single-center study implemented at a general public hospital in Hanoi. Patients aged ≥60 years with at least three chronic diseases admitted to the Internal Medicine Department between August 2020 and December 2020 were eligible to be enrolled. A well-trained clinical pharmacist provided a structured CPS to identify any DRP in prescribing for each patient in the study. Clinical pharmacist interventions were then proposed to the attending physicians and documented in the DRP reporting system. Results: A total of 255 DRP were identified in 185 patients during the study period. The most frequent types of DRP were underuse (21.2%), dose too high (12.2%), and contraindication (11.8%). There was a very high rate of approval and uptake by the physicians regarding the interventions proposed by the clinical pharmacist (82.4% fully accepted and 12.5% partially accepted). Of the interventions, 73.4% were clinically relevant (pADE score ≥0.1). In general, 9 out of 10 physicians agreed that CPS has significant benefits for both patients and physicians. Conclusion: Improving clinical pharmacy services can potentially have a positive impact on the quality of prescribing in elderly inpatients. These services should officially be implemented to optimize the quality use of medicines in this population group in Vietnam.

BACKGROUND: Clinical pharmacy activities have evolved over the past decades contributing to all stages of the patient care process, especially in the hospital setting. However, these practice roles may differ to a significant extent depending on the healthcare policy of countries. In Vietnam, the magnitude of adopting clinical pharmacy activities in hospital settings throughout the country is still unknown since these activities have been implemented. This study aimed to ascertain the current status of clinical pharmacy activities performed within the Vietnamese hospital setting. METHODS: A nation-wide survey was conducted from December 2017 to January 2018. Two online questionnaires, one for the Heads of Pharmacy Department and one for clinical pharmacists, were designed based on the national legal regulations about implementing clinical pharmacy activities in the hospital setting. These questionnaires were sent to all hospitals and healthcare facilities with a department of pharmacy. RESULTS: A total of 560 Heads of Pharmacy and 574 clinical pharmacists participated in the study, representing a response rate of 41.2%. Among the participating hospitals, non-patient specific activities were implemented widely across all hospital classes, with pharmacovigilance, medication information, and standard operating procedures development implemented in ≥88% of all hospitals. In contrast, there was a significant variation in the level of implementation of patient-specific activities among hospital classes. With activities such as medication counselling, monitoring of adverse drug reactions, and obtaining patient's medication histories provided at a considerably lower level in between 49 and 57% of hospitals. CONCLUSION: Clinical pharmacy activities have been initiated in most of the surveyed hospitals. In general, clinical pharmacy is more established in higher-class hospitals in Vietnam. However, the current implementation status is focused on non-patient-specific activities, while patient-oriented activities remained insufficiently established.

OBJECTIVES: This study evaluated the psychometric properties of the Mandarin version of the HeartQoL questionnaire, a core ischemic heart disease (IHD) health-related quality of life (HRQL) instrument, in patients with angina, myocardial infarction (MI), and ischemic heart failure (IHF). METHODS: The English version of HeartQoL was translated into Mandarin. A cross-sectional study was then conducted in mainland China using the Mandarin HeartQoL, Short Form-12 Health Survey, and Hospital Anxiety and Depression Scale. Factor analysis was used to establish the HeartQoL structure and internal consistency reliability and construct validity were assessed. RESULTS: Patients with IHD (n = 412; angina = 112, MI = 151, and IHF = 149) were enrolled. Significantly higher HeartQoL HRQL scores were reported by patients with either angina or MI than by patients with IHF. The 2-factor structure was confirmed by Mokken scale analysis in the total group with strong H coefficients on the global scale (0.64) and both the physical (0.70) and emotional (0.80) subscales. Internal consistency reliability was strong with Cronbach's α ranging from 0.90 to 0.95. Convergent validity was confirmed with strong correlations between similar physical and mental HeartQoL and Short Form-12 Health Survey subscales ranging from 0.77 to 0.82 with divergent validity confirmed with significantly lower correlations between dissimilar constructs. Discriminative validity was confirmed for 72% of the a priori sociodemographic and clinical hypotheses. CONCLUSIONS: The Mandarin version of the HeartQoL HRQL questionnaire demonstrates acceptable internal consistency reliability and convergent, divergent, and discriminative validity in patients with IHD and in each diagnostic subgroup. The data support the use of the HeartQoL to assess and compare HRQL in Mandarin-speaking patients with IHD.

BACKGROUND AND AIMS: Observational studies have demonstrated that the pneumococcal polysaccharide vaccine (PPV) is associated with reduced risk of cardiovascular events. This may be mediated through IgM antibodies to OxLDL, which have previously been associated with cardioprotective effects. The Australian Study for the Prevention through Immunisation of Cardiovascular Events (AUSPICE) is a double-blind, randomised controlled trial (RCT) of PPV in preventing ischaemic events. Participants received PPV or placebo once at baseline and are being followed-up for incident fatal and non-fatal myocardial infarction or stroke over 6 years. METHODS: A subgroup of participants at one centre (Canberra; n = 1,001) were evaluated at 1 month and 2 years post immunisation for changes in surrogate markers of atherosclerosis, as pre-specified secondary outcomes: high-sensitive C-reactive protein (CRP), pulse wave velocity (PWV), and carotid intima-media thickness (CIMT). In addition, 100 participants were randomly selected in each of the intervention and control groups for measurement of anti-pneumococcal antibodies (IgG, IgG2, IgM) as well as anti-OxLDL antibodies (IgG and IgM to CuOxLDL, MDA-LDL, and PC-KLH). RESULTS: Concentrations of anti-pneumococcal IgG and IgG2 increased and remained high at 2 years in the PPV group compared to the placebo group, while IgM increased and then declined, but remained detectable, at 2 years. There were statistically significant increases in all anti-OxLDL IgM antibodies at 1 month, which were no longer detectable at 2 years; there was no increase in anti-OxLDL IgG antibodies. There were no significant changes in CRP, PWV or CIMT between the treatment groups at the 2-year follow-up. CONCLUSIONS: PPV engenders a long-lasting increase in anti-pneumococcal IgG, and to a lesser extent, IgM titres, as well as a transient increase in anti-OxLDL IgM antibodies. However, there were no detectable changes in surrogate markers of atherosclerosis at the 2-year follow-up. Long-term, prospective follow-up of clinical outcomes is continuing to assess if PPV reduces CVD events.

Objective: This systematic review aimed to evaluate the cost-effectiveness of medication adherence-improving interventions in patients with asthma.Data source: Search engines including PubMed, Scopus and EBSCOhost were used to locate relevant studies from the inception of the databases to 19 October 2018. Drummond's checklist was used to appraise the quality of the economic evaluation.Study selection: Economic studies evaluating the cost-effectiveness of medication adherence enhancing interventions for asthmatic patients were selected. Relevant information including study characteristics, quality assessment, health outcomes and costs of intervention were narratively summarized. The primary outcome of interest was cost-effectiveness (CE) values and the secondary outcomes were costs, medication adherence and clinical consequences.Results: Twenty studies including 11 randomized controlled trials, 6 comparative studies and 3 modeled studies using Markov models were included in the review. Among these, 15 studies evaluated an educational intervention with 13 showing cost-effectiveness in improving health outcomes. The CE of an internet-based intervention showed similar results between groups, while 3 studies of simplified drug regimens and adding a technology-based training program achieved the desirable cost-effectiveness outcome.Conclusion: Overall, our results would support that all of the identified medication adherence-enhancing interventions were cost-effective considering the increased adherence rate, improved clinical effectiveness and the reduced costs of asthma care. However, it was not possible to identify the most cost-effective intervention. More economic studies with sound methodological conduct will be needed to provide stronger evidence in deciding the best approach to improve medication adherence.

BACKGROUND: Elderly patients are at high risk of unintentional medication discrepancies during transition of care as they are more likely to have multiple comorbidities and chronic diseases that require multiple medications. OBJECTIVE: The aim of the study was to assess the frequency of unintentional medication discrepancies and identify the associated risk factors and potential clinical impact of them in elderly inpatients during hospital admission. PATIENTS AND METHODS: A prospective observational study was conducted from July to December 2018 in an 800-bed geriatric hospital in Hanoi, North Vietnam. Patients over 60 years of age, admitted to one of selected internal medicine wards, taking at least one chronic medication before admission, and staying at least 48 h were eligible for enrollment. Medication discrepancies of chronic medications before and after admission of each participant were identified by a pharmacist using a step-by-step protocol for the medication reconciliation process. The identified discrepancies were then classified as intentional or unintentional by an assessment group comprising a pharmacist and a physician. A logistic regression model was used to identify risk factors of medication discrepancies. RESULTS: Among 192 enrolled patients, 328 medication discrepancies were identified, with 87 (26.5%) identified as unintentional. Nearly a third of enrolled patients (32.3%) had at least one unintentional medication discrepancy. The most common unintentional medication discrepancy was omission of drugs (75.9% of 87 medication discrepancies). The logistic regression analysis revealed a positive association between the number of discrepancies at admission and the type of treatment wards. CONCLUSIONS: Medication discrepancies are common at admission among Vietnamese elderly inpatients. This study highlights the importance of obtaining a comprehensive medication history at hospital admission and supports implementing a medication reconciliation program to reduce the negative impact of medication discrepancy, especially for the elderly population.
RESUMEN
OBJECTIVE: There is evidence that the pneumococcal polysaccharide vaccine (PPV) may reduce cardiovascular disease. We aimed to evaluate the cost-effectiveness of PPV for primary prevention of acute coronary syndrome (ACS) in the elderly in Australia. METHODS: A Markov model was developed to investigate the costs, QALYs and ICERs of PPV administration in those aged ≥65 years without a history of ACS from the perspective of Australian healthcare system, using elderly-specific clinical data and local costs from Australian Heart Foundation and Australian Institute of Health and Welfare databases. A ten-years horizon was used, and all costs and health outcomes were discounted at 5% annually. The impact of various assumptions was tested with sensitivity analyses. RESULTS: In the base-case analysis, interventional strategy (100% PPV coverage) prevented an additional five incident ACS events among 1000 "healthy" elderly individuals compared with standard of care (50% PPV coverage) over 10 years. 100% PPV was the dominant strategy, resulting in a QALY gain of 0.0075 and cost saving of AU$ 179 per person. The results were most sensitive to effectiveness of PPV at preventing ACS and reducing hospital bed-days, and cost of ACS admission, but in all sensitivity analyses 100% PPV remained the dominant strategy. Shortening the time horizon from ten to five years resulted in further cost saving. CONCLUSION: PPV for the prevention of ACS in those aged ≥65 is a dominant intervention strategy, with cost saving and minor improvements in QALY. Healthcare providers should promote PPV administration for all eligible populations.

OBJECTIVE: The HeartQoL is an ischemic heart disease (IHD) core questionnaire. This study aimed to map the HeartQoL to the EQ-5D to provide the specific patients' health status and utility using one instrument. METHODS: We conducted a cross-sectional study investigating IHD patients in China using the Chinese HeartQoL and EQ-5D. Data based on the total group were fitted by 2 linear regression models with the utility score derived from the EQ-5D as a dependent variable and the HeartQoL total and subscale (physical and emotional) scores as independent variables, respectively. The 2 models were compared via modeling fitting statistics. RESULTS: In total, 406 IHD patients were enrolled in China. The mean HeartQoL global score for the total group was 1.75 (standard deviation [SD] = 0.85), whereas the mean physical and emotional scores were 1.65 (SD = 0.91) and 1.99 (SD = 0.93), respectively. The mean utility calculated by the EQ-5D for IHD patients was 0.66 (SD = 0.38), as compared with 0.95 (SD = 0.06) for healthy people. From the linear regression model with total score, the total score was a significant predictor for the EQ-5D utility, with the equation as EQ-5D = 0.085 - 0.3294 × total. In the linear regression model with physical and mental scores, both scores were significant predictors for the EQ-5D utility, with an equation as EQ-5D = 0.0671- 0.2091 × physical - 0.1248 × mental. The fitting statistics suggest that the model using the HeartQoL total score is preferred. CONCLUSION: As the first effort to map the HeartQoL to EQ-5D, the linear relationship between these 2 instruments was explored, and this could potentially be useful in future health technology assessment decision making and clinical practice.

BACKGROUND: Improving the identification of depression in adults in primary care can produce clinical and economic benefits. Community Pharmacists may play a role in screening for depression. OBJECTIVE: To systematically review and evaluate the evidence for the feasibility, impact and cost-effectiveness of community pharmacists screening adults for depression. METHODS: An electronic literature search using the databases EMBASE, PubMed and CINAHL Complete from January 2000 to September 2019 was undertaken to identify studies involving community pharmacists screening for depression. Data relating to sample size, population demographics and medical conditions of adults screened were extracted. Details around the screening model, process-related outcomes, clinical outcomes and economic outcomes were also extracted. RESULTS: Ten studies using eight unique depression screening tools were identified. Ease of administration was the most common selection criterion (n = 4) while no reason was given in four studies. Seven studies reported that through screening, pharmacists could identify adults with undiagnosed depression. Pharmacists referred adults screening positive for assessment in seven studies and followed up participants in two studies. No study assessed the impact of screening on depressive symptoms or the cost-effectiveness of pharmacists screening for depression. CONCLUSION: Community pharmacists are able to use depression screening tools to identify undiagnosed adults having symptoms of depression. However, there is little evidence around the impact of this screening on clinical and economic outcomes. Larger, well-designed studies that use a highly accurate, easily administered screening tool and include patient referral and follow-up and pharmacist training are warranted to provide evidence on the impact of community pharmacists screening adults for depression.

Background: The association between preterm delivery (PTD) and maternal risk of cardiovascular disease (CVD) was demonstrated, but the economic burden of CVD in these women was unknown. Methods: A Markov microsimulation model, comprising no event, postacute coronary event (ACE, including acute myocardial infarction and unstable angina), poststroke, post-ACE and stroke, postheart failure, and death, was constructed to quantify the CVD burden in women with PTD from 2017 to 2066 using the Australian health care system perspective. Both first-ever and recurrent CVD events were accounted for in the model. Population with PTD histories was sourced from Australian Bureau of Statistics and costs of acute hospitalization and long-term management from government websites. Nonmonetary burden as years of life lost (YLL) was compared between women with and without PTD histories. Both dynamic (i.e., new cohort added every cycle) and static (i.e., population was stabilized) approaches were used to measure the CVD burden, with sensitivity analyses examining the robustness of results. Results: The dynamic model showed the total CVD burden caused by PTD as AUD11.4 billion for the next 50 years and the YLL as 0.34/capita, while the static model generated a cost of AUD4.5 billion and the YLL as 0.52/capita. Long-term management cost was the primary cost determinant (AUD9.4 billion and AUD3.7 billion, respectively) in the two models, with the results most sensitive to the discount rate and time horizon. Conclusions: Considering the substantial economic burden, recognizing PTD as a potential risk factor and encouraging women with PTD histories to participate in primary prevention programs would potentially curb the ever-increasing CVD burden.

Background: In Singapore, the Health Sciences Authority (HSA) reviews an average of 20,000 spontaneous adverse event (AE) reports yearly. Potential safety signals are identified manually and discussed on a weekly basis. In this study, we compared the use of four quantitative data mining (QDM) methods with weekly manual review to determine if signals of disproportionate reporting (SDRs) can improve the efficiency of manual reviews and thereby enhance drug safety signal detection.Methods: We formulated a QDM triage strategy to reduce the number of SDRs for weekly review and compared the results against those derived from manual reviews alone for the same 6-month period. We then incorporated QDM triage into the manual review workflow for the subsequent two 6-month periods and made further comparisons against QDM triage alone.Results: The incorporation of QDM triage into routine manual reviews resulted in a reduction of 20% to 30% in the number of drug-AE pairs identified for further evaluation. Sequential Probability Ratio Test (SPRT) detected more signals that mirror human manual signal detection than the other three methods.Conclusions: The adoption of QDM triage into our manual reviews is a more efficient way forward in signal detection, avoiding missing important drug safety signals.

OBJECTIVES: To examine the cost-effectiveness of a triglyceride lowering medication-icosapent ethyl added on to statin from Australian healthcare system perspective. METHODS: A Markov-model was developed using data from the pivotal trial of icosapent ethyl in a secondary prevention population. Probabilities of CVD events were derived and extrapolated from the published Kaplan-Meier curve using a valid algorithm. Management cost of CVD, health-related quality of life, and background non-CVD mortality were extracted from publicly available sources. Acquisition cost of icosapent ethyl from the United States was used in the current analysis. Australian patients with histories of CVD were modelled for a 25â¯year time horizon and costs and benefits were discounted. Sensitivity analyses (SA) were undertaken. Value of perfect information (VPI) was quantified. RESULTS: Treatment with icosapent ethyl was associated with both higher costs and benefits (i.e. quality-adjusted life year [QALY] and life year [LY]), resulting in an incremental cost-effectiveness ratio (ICER) of AUD59,036/QALY or AUD54,358/LY. Using the often quoted willingness-to-pay (WTP)/QALY of AUD50,000/QALY, icosapent ethyl was not considered cost-effective. SA showed that time horizon, drug cost, and discount rate were the key drivers of the ICER. Total monetary VPI for icosapent ethyl was over AUD15 million over 5â¯years. CONCLUSIONS: Patients with established CVD in whom level of triglycerides is high would benefit from the treatment using icosapent ethyl, however, it is not a cost-effective from an Australian healthcare system perspective. The government may consider subsidising this medication given the clinical need but at a discounted acquisition cost.
