Societal health and economic burden of cardiovascular diseases in the population with type 2 diabetes in Qatar. A 10-year forecasting model.

AIMS: To predict the future health and economic burden of cardiovascular disease (CVD) in type 2 diabetes (T2D) in Qatar. MATERIALS AND METHODS: A dynamic multistate model was designed to simulate the progression of fatal and non-fatal CVD events among people with T2D in Qatar aged 40-79 years. First CVD events [i.e. myocardial infarction (MI) and stroke] were calculated via the 2013 Pooled Cohort Equation, while recurrent CVD events were sourced from the REACH registry. Key model outcomes were fatal and non-fatal MI and stroke, years of life lived, quality-adjusted life years, total direct medical costs and total productivity loss costs. Utility and cost model inputs were drawn from published sources. The model adopted a Qatari societal perspective. Sensitivity analyses were performed to test the robustness of estimates. RESULTS: Over 10 years among people with T2D, model estimates 108 195 [95% uncertainty interval (UI) 104 249-112 172] non-fatal MIs, 62 366 (95% UI 60 283-65 520) non-fatal strokes and 14 612 (95% UI 14 472-14 744) CVD deaths. The T2D population accrued 4 786 605 (95% UI 4 743 454, 4 858 705) total years of life lived and 3 781 833 (95% UI 3 724 718-3 830 669) total quality-adjusted life years. Direct costs accounted for 57.85% of the total costs, with a projection of QAR41.60 billion (US$11.40 billion) [95% UI 7.53-147.40 billion (US$2.06-40.38 billion)], while the total indirect costs were expected to exceed QAR30.31 billion (US$8.30 billion) [95% UI 1.07-162.60 billion (US$292.05 million-44.55 billion)]. CONCLUSIONS: The findings suggest a significant economic and health burden of CVD among people with T2D in Qatar and highlight the need for more enhanced preventive strategies targeting this population group.

Long-term cost-effectiveness of implementing a lifestyle intervention during pregnancy to reduce the incidence of gestational diabetes and type 2 diabetes.

AIMS/HYPOTHESIS: The aim of this study was to determine the long-term cost-effectiveness and return on investment of implementing a structured lifestyle intervention to reduce excessive gestational weight gain and associated incidence of gestational diabetes mellitus (GDM) and type 2 diabetes mellitus. METHODS: A decision-analytic Markov model was used to compare the health and cost-effectiveness outcomes for (1) a structured lifestyle intervention during pregnancy to prevent GDM and subsequent type 2 diabetes; and (2) current usual antenatal care. Life table modelling was used to capture type 2 diabetes morbidity, mortality and quality-adjusted life years over a lifetime horizon for all women giving birth in Australia. Costs incorporated both healthcare and societal perspectives. The intervention effect was derived from published meta-analyses. Deterministic and probabilistic sensitivity analyses were used to capture the impact of uncertainty in the model. RESULTS: The model projected a 10% reduction in the number of women subsequently diagnosed with type 2 diabetes through implementation of the lifestyle intervention compared with current usual care. The total net incremental cost of intervention was approximately AU$70 million, and the cost savings from the reduction in costs of antenatal care for GDM, birth complications and type 2 diabetes management were approximately AU$85 million. The intervention was dominant (cost-saving) compared with usual care from a healthcare perspective, and returned AU$1.22 (95% CI 0.53, 2.13) per dollar invested. The results were robust to sensitivity analysis, and remained cost-saving or highly cost-effective in each of the scenarios explored. CONCLUSIONS/INTERPRETATION: This study demonstrates significant cost savings from implementation of a structured lifestyle intervention during pregnancy, due to a reduction in adverse health outcomes for women during both the perinatal period and over their lifetime.

Characteristics of the clinical pharmacist interventions at the National Center for Cancer Care and Research Hospital in Qatar.

INTRODUCTION: Drug-related problems (DRPs) affect the health outcomes of patients during hospitalization. We sought to analyze the clinical pharmacist-documented interventions among hospitalized patients in the cancer hospital in Qatar. METHODS: A retrospective analysis of electronically reported clinical pharmacist interventions of patients admitted to cancer units at Hamad Medical Corporation, Qatar was conducted. Extracted data was based on an overall 3-month follow-up period; March 1-31, 2018, July 15-August 15, 2018 and January 1-31, 2019. Categorical variables were expressed as frequencies and percentages, while continuous variables were expressed as mean ± standard deviation (SD). RESULTS: A total of 281 cancer patients with 1354 interventions were included. The average age of the study participants was 47 years (SD ± 17.36). The majority of the study population was females (n = 154, 54.80%). The prevailing pharmacist intervention was the addition of a drug therapy (n = 305, 22.53%), followed by medication discontinuation (n = 288, 21.27%) and the addition of a prophylactic agent (n = 174, 12.85%). This pattern was similar across all subgroups (i.e., gender, age, ward), except for the urgent care unit, where an increase in medication dose was the third highest frequently identified intervention (n = 3, 0.22%). The two medication groups associated with the majority of interventions were the anti-infective and fluid/electrolyte agents. Most of the interventions documented were in the oncology ward (73.19%), while the urgent care unit had the least documented interventions (1.62%). CONCLUSIONS: Our analysis showed that clinical pharmacists can effectively identify and prevent DRPs among hospitalized cancer patients.

Cost savings and cost avoidance with the inpatient clinical pharmacist interventions in a tertiary cancer care hospital.

BACKGROUND: The economic benefit of the clinical pharmacist's role in ensuring the optimum use of medicines is potentially considerable, particularly when it comes to cancer management. We sought to evaluate the overall economic impact of clinical pharmacist interventions in the main cancer setting in Qatar. METHODS: The total economic benefit of the clinical pharmacy interventions were analyzed from the public hospital perspective. Patient records in March 2018, July/August 2018, and January 2019 were retrospectively reviewed at the National Center for Cancer Care and Research, Qatar. The total benefit from interventions was the total cost avoidance due to preventable adverse drug events plus any cost savings associated with therapeutic-based resource use. Sensitivity analyses confirmed the results' robustness and increased generalizability. RESULTS: A total of 1352 interventions based on 281 patients were analyzed. The majority of the drug-related problems were related to the appropriateness of therapy, followed by dosing and administration. The total population benefit over the 3-months study period was QAR 4,879,185 (USD 1,336,763), constituting cost avoidance of QAR 4,234,012 (USD 1,160,003) and negative resource-use cost savings of -QAR 645,174 (-USD 176,760). Projected annual overall benefit was QAR 14,355,354 (USD 3,932,974). The increase in resource use with therapies was mostly because of the addition of other medications. Cost avoidance was mostly driven by recommending additional medications and discontinuation of medications. The uncertainty analysis demonstrated the robustness of outcomes. CONCLUSIONS: The clinical pharmacist intervention increased resource use and its cost. In overall, however, taking avoided cost of adverse drug events in consideration, it is an economically beneficial practice in the National Center for Cancer Care and Research setting, associated with adverse drug events prevention and substantial economic benefits.

Characteristics of the clinical pharmacists' interventions at the main general tertiary care hospital in Qatar.

Medication-related problems (MRPs) are prevalent throughout healthcare systems, whereby pharmacy-based interventions are pivotal to reducing occurrence. In the Middle East, including Qatar, the professional roles of pharmacists have been expanding to improve patient safety. This study aimed to characterize and analyze pharmacist-led interventions among hospitalized patients in the leading general hospital in Qatar. A retrospective analysis of pharmacist interventions in the internal medicine ward, critical care unit, and emergency department (ED) was conducted. Data were extracted from three periods of 1 month (March 1-31, 2018, July 15-August 15, 2018, and January 1-31, 2019). A descriptive type of analysis was undertaken. A total of 340 patients with 858 interventions were analyzed. The average age of the study participants was 51 years (SD ± 17.7). The study population was predominantly male (65%). The prevailing pharmacist intervention was adding drug therapy (27%), followed by medication discontinuation (18%) and dosage adjustments (16%). This pattern was maintained across all subpopulations, e.g., gender, age, and ward, except for the ED, where cessation of medication was the most frequent intervention (4%). The two pharmacological classes associated with most interventions were anti-infective and cardiovascular agents. Pharmacist interventions effectively identify, prevent, and resolve MRPs in general inpatient settings in Qatar.

Cost-Effectiveness of Empagliflozin and Metformin Combination Versus Standard Care as First-Line Therapy in Patients With Type 2 Diabetes Mellitus.

OBJECTIVE: Sodium-glucose cotransporter 2 inhibitors have been shown to reduce cardiovascular events but are currently not used as the first-line therapy. This study was conducted to evaluate the cost-effectiveness of first-line empagliflozin plus metformin versus metformin monotherapy among Australians with type 2 diabetes mellitus (T2DM) and existing cardiovascular disease (CVD). METHODS: A Markov model with 1-year cycles and a 5-year time horizon was constructed to simulate the occurrence of recurrent cardiovascular events among Australians aged 50 to 84 years with T2DM and CVD. Efficacy results were derived from the Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients-Removing Excess Glucose trial. Costs and utilities were drawn from published sources. The evaluation adopted both health care and societal perspectives, with the latter ascribing the Australian government's "value of statistical life year" (A$213 000) to each year lived by a person. Future outcomes were discounted at 5% annually. Sensitivity analyses were conducted to enhance the robustness of conclusions. RESULTS: Compared with metformin monotherapy, first-line empagliflozin plus metformin reduced overall cardiovascular events by 0.82% and overall deaths by 7.72% over 5 years. There were 0.2 years of life saved per person and 0.16 quality-adjusted life years gained, at a net health care cost of A$4408. These equated to incremental cost-effectiveness ratios of A$22 076 per year of life saved and A$28 244 per quality-adjusted life year gained. The gains in the value of statistical life year equated to A$42 530 per person, meaning that from a societal perspective, the intervention was cost-saving. CONCLUSION: First-line empagliflozin plus metformin may represent a cost-effective strategy for the management of T2DM and CVD in Australia.

Assessment of Dasatinib Versus Nilotinib as Upfront Therapy for Chronic Phase of Chronic Myeloid Leukemia in Qatar: A Cost-Effectiveness Analysis.

BACKGROUND: The economic outcome research of approved tyrosine kinase inhibitors for treating the chronic phase of chronic myeloid leukemia in developing is scarce. The aim of this study was to assess the cost-effectiveness of dasatinib and nilotinib for newly diagnosed chronic myeloid leukemia patients. METHODS: A decision tree model was developed linking clinical effectiveness (defined as major molecular response) and/or complete cytogenetic response, utility, and cost data over a 12-month period. Patients are recruited from Qatar Cancer Registry. The probability of primary clinical outcome is calculated from DASISION (dasatinib) and ENESTnd (nilotinib) trials. Direct healthcare costs were derived from the national healthcare payer system, whereas adverse effects data were derived from local incident reporting system. RESULTS: In the first-line treatments of chronic myeloid leukemia patients, nilotinib has greater major molecular response (39% nilotinib vs 12% dasatinib) and complete cytogenetic response (24% nilotinib vs 16% dastinib) response outcomes, and more adverse effects than dasatinib (13.3% vs 4%). Moreover, nilotinib is more cost-effective with annual costs (USD63,589.59) and after 12 months of follow-up. Despite the lower acquisition annual cost of dasatinib (USD59,486.30), the incremental cost-effectiveness ratio of nilotinib (vs dasatinib) per major molecular response/complete cytogenetic response achieved was USD15,481.10 per year. There were no cases in both arms that progressed to accelerated or blast phase. At a threshold of 3 times gross domestic product per capita of Qatar and according to World Health Organization recommendation, the nilotinib use is still cost-effective. CONCLUSION: Upfront therapy of chronic myeloid leukemia-chronic phase patients by nilotinib plan appears to be more cost-effective than dasatinib.

Cardiac rehabilitation for participants with implantable cardiac devices: A systematic review and meta-analysis.

Aim: The aim is to discuss efficacy and safety of exercise-based cardiac rehabilitation (CR) programmes in participants with implantable cardiac devices compared with usual care. Methods: MEDLINE, EMBASE and Cochrane databases were searched from inspection till July 15, 2022. Randomized controlled trials were included if they enrolled adult participants with implantable cardiac devices and tested exercise-based CR interventions in comparison with any control. Risk of bias was assessed, and endpoints data were pooled using random-effects model. Results: Sixteen randomized trials enrolling 2053 participants were included. Study interventions differed between studies in terms of programme components, setting, exercise intensity, and follow-up. All studies included physical exercise component. In both implantable cardioverter defibrillators (ICD) and cardiac resynchronization therapy (CRT) groups, exercise training in CR programmes improved peak oxygen uptake (VO2) [(mean difference (MD) 2.08 ml/kg/min; 95 % CI: 1.44-2.728, p < 0.0001; I2 = 99 %) and (MD 2.24 ml/kg/min; 95 % CI: 1.43-3.04, p < 0.0001; I2 = 96 %), respectively] and 6-min walk test in ICD group (MD 41.51 m; 95 % CI: 15.19-67.82 m, p = 0.002; I2 = 95 %) compared with usual care. In CRT group, there was no statistically significant improvement in left ventricular ejection fraction change between comparison groups. The results were consistent in subgroup analysis according to high or low-to-moderate exercise intensity for change in peak VO2 and ejection fraction in CRT group. There was no difference in number of ICD shocks between the comparators. Conclusion: Exercise-based CR programmes appear to be safe when enrolling participants with implantable cardiac devices and leading to favourable functional outcomes.

Beta-blocker therapy in heart failure with preserved ejection fraction (B-HFpEF): A systematic review and meta-analysis.

INTRODUCTION: While beta-blockers are considered the cornerstone of treatment for heart failure with reduced ejection fraction, the same may not apply to patients with heart failure with preserved ejection fraction (HFpEF). To date, the benefit of beta-blockers remains uncertain, and there is no current consensus on their effectiveness. This study sought to evaluate the efficacy of beta-blockers on mortality and rehospitalization among patients with HFpEF. METHODS: A systematic review and meta-analysis of randomized or observational cohort studies examined the efficacy of beta-blocker therapy in comparison with placebo, control, or standard medical care in patients with HFpEF, defined as left ventricular ejection fraction ≥50 %. The main endpoints were mortality (i.e., all-cause and cardiovascular), rehospitalization (i.e., all-cause and for heart failure) and a composite of the two. RESULTS: Out of the 13,189 records initially identified, 16 full-text records met the inclusion criteria and were analyzed recruiting a total of 27,188 patients. The mean age range was 62-84 years old, predominantly female, with HFpEF in which 63.4 % of patients received a beta-blocker and 36.6 % did not. The pooled analysis of included cohort studies, of variable follow-up durations, showed a significant reduction in all-cause mortality by 19 % (odds ratio (OR) 0.81; 95 % confidence interval (CI): 0.65-0.99, p = 0.044) whereas rehospitalization for heart failure (OR 1.13; 95 % CI: 0.91-1.41, p = 0.27) or its composite with all-cause mortality (OR 1.01; 95 % CI: 0.78-1.32, p = 0.92) were similar between the beta-blocker and control groups. CONCLUSION: This meta-analysis showed that beta-blocker therapy has the potential to reduce all-cause mortality in patients with HFpEF based on observational studies. Nevertheless, it did not affect rehospitalization for heart failure or its composite with all-cause mortality. Large scale randomized trials are needed to clarify this uncertainty.

Efficacy and safety of selinexor for patients with relapsed and refractory multiple myeloma: A meta-analysis.

PURPOSE: Selinexor is a first-in-class, oral selective-inhibitor-of-nuclear-export, granted accelerated approval by FDA (2019) for relapsed and refractory multiple myeloma (RRMM). We sought to quantitatively summarize the selinexor efficacy and safety in RRMM. METHODS: We searched PubMed, EMBASE, CENTRAL, clinicaltrial.gov, and google scholar, until May 2023, studies about selinexor use in RRMM. The outcome measures of interest were primarily efficacy outcomes, in addition to safety outcomes. Random-effect model analyses were performed, at statistical significance of P<0.05, using the RevMan software. RESULTS: Meta-analyses of eleven included clinical trials yielded a significant 56.21% overall clinical benefit, 46.91% overall response, 4.89% complete response, 23.41% very good partial response, 24.68% partial response, and 28.06% stable disease rates with selinexor. Due to safety reasons, selinexor caused significant increase in discontinuation rate, 16.80%. Subgroup analyses demonstrated higher efficacy with selinexor plus dexamethasone and proteasome inhibitor combinations than with selinexor alone. The multiple myeloma type, high cytogenetic risk, refractory state, and advanced disease state did not affect performance. Risk of selection, performance, and detection biases were unclear in the included trials. CONCLUSION: Selinexor led to significant positive responses with an acceptable safety profile in RRMM patients, despite higher rates of safety-related discontinuations. Selinexor-based combinations further enhanced response.

Cost-effectiveness of l-glutamine versus crizanlizumab for adults with sickle cell disease: model focused on reducing pain episode costs from Qatar's healthcare perspective.

Objectives: Treatment options for preventing vaso-occlusive crises among sickle cell disease patients are on the rise, especially if hydroxyurea treatment has failed. This economic analysis is conducted to assess the comparative clinical effectiveness, safety, and acquisition cost of l-glutamine and crizanlizumab for older adolescents and adults (⩾16 years old) with sickle cell disease in Qatar, with an emphasis on treatment costs and acute pain crises. Methods: We conduct a decision-tree model, where we compare the clinical and economic outcomes of two novel Food and drug administration (FDA)-approved medications which are available in Qatar; l-glutamine and crizanlizumab over a time horizon of 1 year in a hypothetical cohort of adult sickle cell disease patients from a Qatar healthcare perspective. The main outcome is incremental cost per sickle cell disease-related acute pain crises averted. Model clinical parameters were derived from individual drug randomized trials, published literature, whereas cost parameters from Qatar healthcare payer system (2020-2021). A sensitivity analysis was carried out, and the study results were robust around model inputs. Costs were converted to 2020 US dollars. Results: Study results showed that both treatment modalities' costs were the main driver of this analysis, with an average annual cost of the treatments per patient being $189,014 for crizanlizumab (5 mg/kg), $143,798 for crizanlizumab (2.5 mg/kg), and $74,323 for l-glutamine. The probability of no first-time sickle cell disease-related vaso-occlusive crises averted was 0.001/year for glutamine, 0.26/year for crizanlizumab (5 mg/kg), and 0.34/year for crizanlizumab (2.5 mg/kg). Lower dose crizanlizumab (2.5 mg/kg) dominated the higher one (5 mg/kg). The incremental cost-effectiveness ratio of crizanlizumab (2.5 mg/kg), when compared to l-glutamine was $81,265 per sickle cell disease-related vaso-occlusive crises averted. When comparing crizanlizumab (5 mg/kg) and l-glutamine, crizanlizumab (5 mg/kg) showed higher efficacy, yet the crizanlizumab incremental cost-effectiveness ratio was at $459,620 than l-glutamine. Conclusions: Crizanlizumab (2.5 mg/kg) may be a cost-effective intervention, yet it is not the approved dose for preventing vaso-occlusive crises in adolescents and adults with sickle cell disease. Crizanlizumab (5 mg/kg) was more cost-effective than the approved l-glutamine per sickle cell disease vaso-occlusive crisis prevented. Of note, we primarily focused on modeling acute vaso-occlusive pain, which limited our ability to consider other key outcomes in sickle cell disease.

Cost­effectiveness of add­on dapagliflozin for heart failure with reduced ejection fraction patients without diabetes.

AIM: To evaluate the cost-effectiveness of dapagliflozin added to standard of care (SoC) versus SoC in heart failure with reduced ejection fraction (HFrEF) and without type 2 diabetes mellitus (T2DM) patients from the Qatari healthcare perspective. MATERIALS AND METHODS: A lifetime Markov model was developed to evaluate the cost-effectiveness of adding dapagliflozin to SoC based on the findings of Petrie et al. 2020, which were based on the DAPA-HF trial. The model was constructed based on four health states: "alive with no event", "urgent visit for heart failure", "hospitalization for heart failure", and "dead". The model considered 1,000 hypothetical HFrEF and without T2DM patients using 3-month cycles over a lifetime horizon. The outcome of interest was the incremental cost-effectiveness ratio (ICER) per quality-adjusted life-year gained (QALY) and years of life lived (YLL). Utility and cost data were obtained from published sources. A scenario analysis was performed to replace the transition probabilities of events in people without T2DM with the transition probabilities of events irrespective of T2DM status, based on findings of the DAPA-HF trial. Sensitivity analyses were conducted to confirm the robustness of the conclusion. RESULTS: Adding dapagliflozin to SoC was estimated to dominate SoC alone, resulting in 0.6 QALY and 0.8 YLL, at a cost saving of QAR771 (USD211) per person compared with SoC alone, with total healthcare costs of QAR42,413 (USD 11,620) versus 43,184 (USD11,831) per person, respectively. When replacing the transition probabilities of events in people without T2DM with the transition probabilities of events in people irrespective of T2DM status, dapagliflozin was cost-effective at ICER of QAR5,212 (USD1,428) per QALY gained and QAR3,880 (USD1,063) per YLL. In the probabilistic sensitivity analysis, dapagliflozin combined with SoC was cost saving in over 49% of the cases and cost-effective in over 43% of the simulated cases against QALYs gained and YLL. LIMITATIONS: Data from clinical trials were used instead of local data, which may limit the local relevance. However, evidence from the local Qatari population is lacking. Also, indirect costs were not included due to a paucity of available data. CONCLUSIONS: Adding dapagliflozin to SoC is likely to be a cost-saving therapy for patients with HFrEF and without T2DM in Qatar.

Heart failure with reduced ejection fraction is a type of heart failure characterized by left ventricular ejection fraction of 40% or less. Dapagliflozin is a novel therapy for this condition, which was initially designed to treat type 2 diabetes mellitus. It is unclear whether dapagliflozin is a cost-effective option for patients with heart failure with reduced ejection fraction and without type 2 diabetes. A lifetime Markov model was developed to evaluate the cost-effectiveness of adding dapagliflozin to standard of care from the Qatari healthcare perspective. Model results suggest that adding dapagliflozin to standard of care dominated standard of care alone, resulting in a gain of 0.8 years of life lived, a gain of 0.6 quality-adjusted life-years, and a cost saving of 211 United States dollars per person.

Cost-Effectiveness of Screening Strategies for Familial Hypercholesterolaemia: An Updated Systematic Review.

BACKGROUND: OBJECTIVE: This study aimed to systematically synthesise the cost-effectiveness of screening strategies to detect heterozygous familial hypercholesterolemia (FH). METHODS: We searched seven databases from inception to 2 February , 2023, for eligible cost-effective analysis (CEA) that evaluated screening strategies for FH versus the standard care for FH detection. Independent reviewers performed the screening, data extraction and quality evaluation. Cost results were adapted to 2022 US dollars (US$) to facilitate comparisons between studies using the same screening strategies. Cost-effectiveness thresholds were based on the original study criteria. RESULTS: A total of 21 studies evaluating 62 strategies were included in this review, most of the studies (95%) adopted a healthcare perspective in the base case, and majority were set in high-income countries. Strategies analysed included cascade screening (23 strategies), opportunistic screening (13 strategies), systematic screening (11 strategies) and population-wide screening (15 strategies). Most of the strategies relied on genetic diagnosis for case ascertainment. The most common comparator was no screening, but some studies compared the proposed strategy versus current screening strategies or versus the best next alternative. Six studies evaluated screening in children while the remaining were targeted at adults. From a healthcare perspective, cascade screening was cost-effective in 78% of the studies [cost-adapted incremental cost-effectiveness ratios (ICERs) ranged from dominant to 2022 US$ 104,877], opportunistic screening in 85% (ICERs from US$4959 to US$41,705), systematic screening in 80% (ICERs from US$2763 to US$69,969) and population-wide screening in 60% (ICERs from US$1484 to US$223,240). The most common driver of ICER identified in the sensitivity analysis was the long-term cost of lipid-lowering treatment. CONCLUSIONS: Based on reported willingness to pay thresholds for each setting, most CEA studies concluded that screening for FH compared with no screening was cost-effective, regardless of the screening strategy. Cascade screening resulted in the largest health benefits per person tested.

A cost-effectiveness analysis for high versus standard (low) dose caffeine for the treatment of apnea in neonatal intensive care unit.

Objective: Preterm babies are prone to experiencing apnea of prematurity (AOP), mostly characterised by a pause in breathing lasting a minimum of 20 seconds. Recent literature supported higher maintenance doses of caffeine, indicating benefits. This study evaluated the cost-effectiveness of high maintenance dose (HD) versus low maintenance dose (LD) caffeine for AOP in neonates. Methods: From the hospital perspective of Hamad Medical Corporation (HMC), Qatar, a cost-effectiveness decision-analytic model was constructed to follow the use of a HD maintenance caffeine of 20 mg/kg/dose versus a LD maintenance caffeine of 10 mg/kg/dose, in a simulated cohort of AOP neonates, over a therapy follow-up duration of six weeks, until neonatal intensive care (NICU) discharge. The clinical inputs were primarily literature-based, while the resource cost and utilisation were locally extracted in HMC. The cost-effectiveness outcome measure was calculated per therapy success, defined as survival with no apnea and successful extubation removal within 72 hours, with or without adverse events. One-way and multivariate sensitivity analyses were performed to confirm the robustness of the results. Results: With 0.23 (95% CI, 0.23-0.23) enhancement in success rate, at United States dollar (US$) 3869 (95% CI, US$ 3823-3915) added infant cost, the HD caffeine was between dominant (34.8%) and cost-effective (63.7%), with an average incremental cost-effectiveness ratio of US $16,895 (95% CI, US$ 15,242-18,549) relative to LD caffeine per additional case of success. The hospitalisation contributed the most to the total infant cost, and the probability of patent ductus arteriosus was the model input that influenced the results most. Conclusion: This is the first literature economic evaluation of caffeine for AOP. Despite increasing the cost of therapy, HD maintenance caffeine seems to be a cost-effective alternative to LD caffeine in Qatar. Our results support the recent global trends of increased use of HD caffeine for AOP in NICU.

Clinical pharmacists' interventions for preventing adverse events in critically ill neonates in Qatar: an economic impact analysis.

Objective: This study aimed to assess the overall economic impact of clinical pharmacist interventions in the neonatal ICU (NICU) in Qatar. Methods: A retrospective review of neonates' records was performed over a 3-month duration in the NICU of Qatar to determine the total economic benefit of clinical pharmacist interventions. The total benefit of interventions was calculated by considering the cost avoidance due to preventable adverse drug events (ADEs) and the cost savings associated with the revised resource use due to interventions. Sensitivity analyses were conducted to ensure the robustness and generalizability of the results. Results: A total of 513 interventions were analyzed, involving 150 neonates. Most of the drug-related problems were related to therapy dosing, followed by drug choice appropriateness, the addition of prophylactic treatment, and administration frequency. The overall annual benefit was estimated at QAR 4,178,352 (1,147,584), which consisted of cost avoidance of QAR 1,050,680 (USD 288,648) and an overall cost saving of QAR -6091 (USD -1673). Conclusions: While the clinical pharmacist interventions led to increased resource utilisation and associated costs, when considering the avoided costs of ADEs, the overall clinical pharmacist practices in the NICU setting were economically beneficial.

The cost associated with the development of the antimicrobial stewardship program in the adult general medicine setting in Qatar.

Objective: To estimate the economic impact of the developed antimicrobial stewardship program (ASP) versus the preliminary ASP use, in the adults' general medicine settings in Qatar. Methods: Patient records were retrospectively reviewed during two periods: preliminary ASP was defined as the 12 months following ASP implementation (i.e. May 2015-April 2016), and developed ASP was defined as the last 12 months of a 5-year ASP implementation in Hamad Medical Corporation (HMC) (i.e. February 2019-January 2020). The economic impact was the overall cost savings in resource use, including operational costs, plus the cost avoidance associated with ASP. Results: A total of 500 patients were included in the study. The operational costs decreased with the developed ASP. Whereas antimicrobial consumption and resource utilisation, and their associated costs, appear to have declined with the developed ASP, with a cost saving of QAR458 (US$125) per 100-patient beds, the avoided cost was negative, by QAR4,807 (US$1,317) per 100-patient beds, adding to a total QAR4,224 (US$1,160) increase in the 100-patient beds cost after ASP development. Conclusions: Despite that the developed ASP attained a total cost saving QAR458 (US$125) per 100-patient beds, the avoided cost was QAR-4,807 (US$-1,317) per 100-patient beds, which exceeded the cost savings achieved.

Epidemiology, clinical characteristics, and associated cost of acute poisoning: a retrospective study.

Introduction: Poisoning is a major public health issue and a leading cause of admission to the emergency department (ED). There is a paucity of data describing the epidemiology and cost of acute poisoning. Therefore, this study investigated the epidemiology, patterns, and associated costs of acute poisoning in emergency department of the largest tertiary care healthcare centre in Qatar. Method: This study was a retrospective review of the health records of patients admitted to the ED due to poisoning between January 2015 and December 2019. Incidence, clinical characteristics, and costs associated with acute poisoning were assessed. Frequency and percentages were calculated for categorical variables and mean and SD for continuous variables. The relationship between sociodemographic characteristics and poisoning profile was assessed using the chi-square test. A micro-costing approach using the cost of each resource was applied for cost calculations. Result: The incidence of acute poisoning was 178 cases per 100,000 patients. Females (56%) and children below 14 years (44.3%) accounted for the largest proportion. Most of the exposures were accidental involving therapeutic agents (64.2%). The mean length of hospital stay was found to be 1.84 ± 0.81 days, and most patients (76.6%) were discharged within the first 8 h. A statistically significant difference was found between age groups and type of toxin (χ2 = 23.3, p < 0.001), cause and route of exposure (χ2 = 42.2, p < 0.001), and length of hospital stay (χ2 = 113.16, p < 0.001). Admission to intensive care units had the highest cost expenditure (USD 326,008), while general wards accounted for the least (USD 57,709). Conclusion: Unintentional poisoning by pharmacological agents is common in infants and children. This study will assist in the development of educational and preventive programmes to minimise exposure to toxic agents. Further studies are required to explore the impact of medical toxicology services, and post discharge monitoring of poisoning.

Percutaneous Mitral Valve Repair for Secondary Mitral Regurgitation: A Systematic Review and Meta-Analysis.

This systematic review and meta-analysis aimed to investigate whether percutaneous mitral valve repair (PMVr) using MitraClip was more effective than surgery or medical therapy for long-term morbidity and mortality. We searched MEDLINE, EMBASE, and CENTRAL (Cochrane Library) databases to identify relevant studies that recruited adult patients with functional or secondary mitral valve regurgitation who underwent PMVr with MitraClip implantation using appropriate search terms and Boolean operators. The odds ratios (ORs) were pooled using the random-effects model. A total of 14 studies recruiting 2,593 patients were included. Within 12 months of follow-up, patients who underwent PMVr did not maintain mitral valve regurgitation grade 2+ (OR 0.22, 95% confidence interval [CI] 0.12 to 0.41, p <0.0001, I2 = 0.0%, p = 0.52) or symptom-free heart failure (OR 0.47, 95% CI 0.29 to 0.77, p = 0.0028, I2 = 0.0%, p = 0.66) compared with their surgical counterparts. Patients were more likely to be rehospitalized for heart failure (OR 2.79, 95% CI 1.54 to 5.05, p = 0.0007, I2 = 0.0%, p = 0.51). However, there was no difference between the groups in terms of all-cause or cardiovascular mortality. Whereas, in comparison with medical therapy, PMVr significantly reduced all-cause mortality at 12 and ≥24 months of follow-up (OR 0.41, 95% CI 0.24, 0.69, p = 0.0009, I2 = 32%, p = 0.23 and OR 0.55, 95% CI 0.40, 0.75, p = 0.0002, I2 = 0.0%, p = 0.45, respectively). In conclusion, there was no difference in all-cause death at 12 or 24 months of follow-up between PMVr and the surgical approach, but the durability of valvular repair was inferior with PMVr. In comparison with medical therapy, there was a significant reduction in mortality with PMVr.

Percutaneous Mitral-Valve Intervention for Secondary Mitral Regurgitation: Data From Real-Life.

Many questions were raised due to the divergent results between cardiovascular outcomes assessment of the MitraClip percutaneous therapy for heart failure patients with functional mitral regurgitation (COAPT) and multicenter study of percutaneous mitral valve Repair MitraClip device in patients with severe secondary mitral regurgitation (MITRA-FR) trials on the use of percutaneous mitral valve repair for secondary mitral regurgitation. This paper examined pooled patients' characteristics and outcomes from real-life experience compared with those in the 2 landmark trials. A comprehensive search identified eligible studies published in 2020 and 2021. Mean difference and odds ratio (OR) were used to compare continuous and categorical data. Thirty-three studies included more than 9200 patients. Patients in landmark trials were younger than in real-life, less likely to present with severe heart failure symptoms ([COAPT: OR 0.25; 95% CI: 0.21, 0.31]; [MITRA-FR: OR 0.32; 95% CI: 0.23, 0.45]) or severe mitral regurgitation grade (COAPT only: OR 0.57; 95% CI: 0.45, 0.71) with larger left ventricular end diastolic volume. Procedure success (OR 1.94; 95% CI: 1.10, 3.40) was more frequent with lower all-cause mortality (OR 0.73; 95% CI: 0.54, 0.99) in COAPT. Real-life patients experienced more favorable procedural and clinical outcomes compared with MITRA-FR patients. Real-life data on percutaneous mitral valve repair in secondary mitral regurgitation showed important variations in patient selection and procedural outcomes. Rates of death and heart failure hospitalization in observational studies were lower than MITRA-FR but higher than COAPT trial.

Cost-Effectiveness Analysis of Ibuprofen Versus Indomethacin or Paracetamol for the Treatment of Patent Ductus Arteriosus in Preterm Neonates.

This was a first-time evaluation that sought to analyze the cost-effectiveness of oral paracetamol and intravenous (IV) indomethacin as alternatives to ibuprofen for PDA in neonates. Decision-analytic, literature-based, economic simulation models were constructed, to follow up the use and consequences of oral/IV ibuprofen versus IV indomethacin, and oral/IV ibuprofen versus oral paracetamol, as first-line therapies for PDA closure. Model outcomes of interest were "success", defined as PDA closure with/without adverse events, or "failure" due to no response to the first course of treatment, death or premature discontinuation of therapy due to adverse events. Oral ibuprofen is dominant/cost-effective over IV indomethacin in 97.9% of simulated cases, but oral paracetamol was 75.2% dominant/cost-effective over oral ibuprofen. Against IV ibuprofen, IV indomethacin was 55.3% dominant/cost-effective, whereas oral paracetamol was dominant/cost-effective in 98.5% of the cases. Sensitivity analyses confirmed the robustness of the study results. For PDA closure, while IV indomethacin was cost-effective against IV ibuprofen, oral paracetamol was cost-effective against both oral and IV ibuprofen.
