Cost-effectiveness analysis of pharmacist interventions in patients with heart failure in Thailand.

INTRODUCTION: Patients with heart failure (HF) are likely to have multiple diseases with complex therapy regimens. Pharmacist intervention in HF treatment can reduce all-cause mortality and hospitalization, but the economic outcome is not known. OBJECTIVE: This study aimed to assess the cost-effectiveness of pharmacist contribution in HF setting compared with usual care. METHODS: A decision analytical model was developed to estimate the cost and outcome from a health care system perspective in Thailand. Clinical inputs were obtained from literature review. Pharmacist costs, hospitalization cost for HF, risk of hospitalization death, risk of nonhospitalization death, and readmission rate were based on data from Thailand. The cost and outcome were discounted at 3% annually. OUTCOME MEASURES: The incremental cost-effectiveness ratio (ICER) was calculated and presented for the year 2020. A series of sensitivity analysis was also performed. RESULTS: Pharmacist intervention incurred higher total costs than usual care, because total cost of pharmacists was 186,040 THB (5936 USD) whereas usual care cost was 151,654 THB (4839 USD). It also provided more quality-adjusted life years (QALYs) than usual care, from 2.4 to 2.8. In addition, patient life years (LY) were increasing from 3.3-3.8. This yielded an ICER of 77,398 THB/LY (2467 USD/LY) or 103,037 THB/QALYs (3288 USD/QALYs). This ICER is considered to be cost-effective at the willingness-to-pay level of 160,000 THB/QALY (5191.87 USD). CONCLUSION: At this current situation in Thailand, pharmacists may represent good value for the nation's limited health care resources. The information should be used in national policies to plan for pharmacist work force implementation and production line in the near future.

Effectiveness of Receptive Music Therapy with Imbedded 10 Hz Binaural Beats Compared with Standard Care for Patients with Major Depressive Disorder: A Randomized Controlled Trial.

OBJECTIVES: The purpose of this study was to determine the effectiveness of music therapy (MT) with imbedded 10 Hz binaural beats in combination with standard treatment in comparison to standard treatment alone in patients diagnosed with major depressive disorder (MDD). METHODS: This study was a randomized controlled trial enrolling 18 MDD adult patients aged ≥20 years old with mild to moderate levels of acute phase depression. The intervention group received MT along with standard treatment, while the control group received only standard treatment. 10-Hz binaural beats were embedded into soothing music. The participants listened to the MT via stereo headphones for 20 min at the clinic and were instructed to continue listening to the track at home at least 3 times/week. The primary outcome was depression score using patient health questionnaire depression screening (PHQ-9). The secondary outcomes were quality of life, measured by the Euro Quality of Life Five-Dimension (EQ-5D) rating, and medications adherence, measured by the medication adherence rating scale (MARS). The outcomes were measured at week 0, week 4, and week 8. RESULTS: At baseline, the primary outcome of PHQ-9 did not differ between the MT group and the control group (13.3 ± 4.4; 13.9 ± 3.37; p-value = 0.77). After a follow-up of 4 and 8 weeks, the PHQ-9 in the MT group was lower than the control group by 1.50 (95 % confidence interval: -4.46 to 1.46). However, this difference was not significant, with p-value = 0.32. As for the secondary outcome, there were no significant differences in terms of EQ-5D and MARS. CONCLUSIONS: This study concluded that MDD patients who received 10-Hz binaural beat imbedded MT combined with standard treatment had experienced no significant differences compared with control group in terms of depression score, quality of life, and medication adherence. Further studies are suggested to investigate the long-term effect of MT with binaural beats.

Prediction Of Serum Digoxin Concentration Using Estimated Glomerular Filtration Rate In Thai Population.

PURPOSE: Serum digoxin concentration (SDC) monitoring may be unavailable in some healthcare settings. Predicted SDC comes into play in the efficacy and toxicity monitoring of digoxin. Renal function is the important parameter for predicting SDC. This study was conducted to compare measured and predicted SDC when using creatinine clearance (CrCl) from Cockcroft-Gault (CG) equation and estimated glomerular filtration rate (eGFR) calculated from CKD-Epidemiology Collaboration (CKD-EPI), re-expressed Modification of Diet in Renal Disease (Re-MDRD4), Thai-MDRD4, and Thai-eGFR equations in Sheiner's and Konishi's pharmacokinetic models. PATIENTS AND METHODS: In this retrospective study, patients with cardiovascular disease with a steady-state of SDC within 0.5-2.0 mcg/L were enrolled. CrCl and studied eGFR adjusted for body surface area (BSA) were used in the models to determine the predicted SDC. The discrepancies of the measured and the predicted SDC were analyzed and compared. RESULTS: One hundred and twenty-four patients ranging in age from 22 to 88 years (median 60 years, IQR 50.2, 69.2) were studied. Their serum creatinine ranged from 0.40 to 1.80 mg/dL (median 0.90 mg/dL, IQR 0.79, 1.10). The mean±SD of measured SDC was 1.12±0.34 mcg/L. In the Sheiner's model, the mean predicted SDC was calculated by using the CG and the BSA adjusted CKD-EPI equations and was not different when compared with the measured levels (1.10±0.36 mcg/L (p=0.669) and 1.08±0.42 mcg/L (p=0.374), respectively). The CG, CKD-EPI, and Re-MDRD4 equations were a better fit for patients with creatinine ≥0.9 mg/dL for prediction with minimal errors. In the Konishi's model, the predicted SDC using the CG and the studied eGFR equation was lower than the measured SDC (p<0.05). CONCLUSION: In Sheiner's model, the CG and the BSA adjusted CKD-EPI equations should be used for predicting SDC, especially in patients with serum creatinine ≥0.9 mg/dL. The other studied eGFRs underestimated SDC in both Sheiner's and Konishi's model.

Roles of pharmacogenomics in non-anthracycline antineoplastic-induced cardiovascular toxicities: A systematic review and meta-analysis of genotypes effect.

BACKGROUND: Exploration on genetic roles in antineoplastic-related cardiovascular toxicity has increased with the advancement of genotyping technology. However, knowledge on the extent of genetic determinants in affecting the susceptibility to the cardiovascular toxicities of antineoplastic is limited. This study aims to identify potential single nucleotide polymorphism (SNP) in predicting non-anthracycline antineoplastic-related cardiovascular toxicity. METHODS: We systematically searched for original research in PubMed, Cochrane Central Register of Controlled Studies, CINAHL Plus, EMBASE and HuGE Navigator from database inception until January 2018. Studies on association between polymorphism and antineoplastic-induced cardiovascular toxicity in patients treated for cancer of all antineoplastic agents were included except for anthracycline. Case reports, conference abstracts, reviews and non-patient studies were excluded. Data extracted by two independent reviewers were combined with random-effects model and reported according to PRISMA and MOOSE guidelines. RESULTS: The 35 studies included examined a total of 219 SNPs in 80 genes, 11 antineoplastic and 5 types of cardiovascular toxicities. Meta-analyses showed that human epidermal growth factor receptor 2 (HER2) rs1136201, a risk variants (pooled OR: 2.43; 1.17-5.06, p = 0.018) is a potential predictors for trastuzumab-related cardiotoxicity. Gene dose effect analysis showed number of variant allele may contribute to the risk too. CONCLUSIONS: This review found that HER2 rs1136201 can have the potential in predicting trastuzumab-related heart failure. As such, further studies are needed to confirm the validity of these results as well as determine the economic aspect of using SNPs prior to its implementation as a clinical practice.

Pharmacological treatments for heart failure with preserved ejection fraction-a systematic review and indirect comparison.

Pharmacological interventions for heart failure with preserved ejection fraction (HFpEF) have failed to reduce mortality and hospitalization. Evidence for mineralocorticoid antagonists (MRAs), ß-adrenoceptor blockers (ß-blockers), and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACEIs/ARBs)-to reduce clinical outcomes in HFpEF remains unclear. We conducted a systematic search of MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and Clinical Trials.gov for randomized controlled trials (RCTs) assessing pharmacological treatments in HFpEF diagnosed according the recommendations of the European Society of Cardiology (ESC) 2016 guidelines from inception to August, 2017. The study outcomes were mortality, hospitalization, changes in indexes of cardiac structure and function, biomarkers, and indexes of functional capacity-quality of life (QoL) assessment and 6-min walk distance test (6-MWD). The random-effects models were used to estimate pooled relative risks (RRs) for the binary outcomes and standardized mean differences for continuous outcomes, with 95% CI. A network meta-analysis using a random-effects model was employed to estimate the comparative efficacy of treatments. We included data from 15 RCTs comprising 5930 patients. There was no significant effect seen with all treatments compared with placebo and comparative efficacy of any two treatments on all outcomes assessed. However, mineralocorticoid antagonist spironolactone demonstrated a trend towards reducing mortality compared with placebo (RR 0.92; 95% CI 0.79-1.08), sildenafil (0.14; 0.01-2.78), perindopril (0.87; 0.59-1.28), and eplerenone (0.91; 0.25-3.33). Similar trends in treatment effect were observed with spironolactone on surrogate outcomes while eplerenone demonstrated a trend of superior effect in reduction of hospitalizations compared with all other drug treatment. No drug treatment demonstrated statistically significant improvement in clinical and surrogate outcomes in HFpEF diagnosed according to the ESC 2016 guideline. Spironolactone and eplerenone showed clinically relevant reduction in mortality and hospitalization respectively compared with other drug treatments. Further trials with MRAs are warranted to confirm treatment effects in HFpEF.
