ABSTRACT Studies found a strong association between HLA-B*13:01 allele and co-trimoxazole-induced severe cutaneous adverse reactions (SCARs). Genetic screening before initiation of co-trimoxazole may decrease the incidence of co-trimoxazole-induced SCARs. This study aims to evaluate the cost-effectiveness of HLA-B*13:01 screening before co-trimoxazole initiation in HIV-infected patients in Thailand. A combination of a decision tree model and a Markov model was used to estimate lifetime costs and outcomes of two strategies including 1) HLA-B*13:01 screening before co-trimoxazole initiation and 2) usual practice from a societal perspective. Alternative drugs are not considered because dapsone (the second-line drug) also presents a genetic risk. Input parameters were obtained from literature, government documents, and part of the TREAT Asia HIV Observational Database (TAHOD). One-way sensitivity analyses and probabilistic analyses were performed to determine robustness of the findings. HLA-B*13:01 screening resulted in 0.0061 quality-adjusted life years (QALYs) loss with an additional cost of 370 THB ($11.84). At the cost-effectiveness threshold of 160,000 THB ($5,112.85), the probability of the genetic screening strategy being cost-effective is 9.54%. This analysis demonstrated that HLA-B*13:01 allele screening before initiation of co-trimoxazole among HIV-infected patients is unlikely to be cost-effective in Thailand. Our findings will help policymakers make an evidence-informed decision making.

Aims: Left atrial appendage closure (LAAC) has been demonstrated to be cost-saving relative to oral anticoagulants for stroke prophylaxis in patients with non-valvular atrial fibrillation (NVAF) in the US and Europe. This study assessed the cost-effectiveness of LAAC with the Watchman device relative to warfarin and direct oral anticoagulants (DOACs) for stroke risk reduction in NVAF from a Japanese public healthcare payer perspective. Methods: A Markov model was developed with 70-year-old patients using a lifetime time horizon. LAAC clinical inputs were from pooled, 5-year PROTECT AF and PREVAIL trials; warfarin and DOAC inputs were from published meta-analyses. Baseline stroke and bleeding risks were from the SALUTE trial on LAAC. Cost inputs were from the Japanese Medical Data Vision database. Probabilistic and one-way sensitivity analyses were performed. Results: Over the lifetime time horizon, LAAC was less costly than warfarin (savings of JPY 1,878,335, equivalent to USD $17,600) and DOACs (savings of JPY 1,198,096, equivalent to USD $11,226). LAAC also provided 1.500 more incremental quality-adjusted life years (QALYs) than warfarin and 0.996 more than DOACs. In probabilistic sensitivity analysis, LAAC was cost-effective relative to warfarin and DOACs in 99.98% and 99.73% of simulations, respectively. LAAC dominated (had higher cumulative QALYs and was less costly than) warfarin and DOACs in 89.94% and 83.35% of simulations, respectively. Conclusions: Over a lifetime time horizon, LAAC is cost-saving relative to warfarin and DOACs for stroke risk reduction in NVAF patients in Japan and is associated with improved quality of life.

AIMS Thailand’s national smoking cessation services (FAH-SAI clinics) were founded in 2010. A cost-effectiveness analysis (CEA) is needed to inform policymakers of the allocation and prioritization of the limited budget to maximize the value for money of reimbursing these services. Chronic obstructive pulmonary disease (COPD) patients would benefit from smoking cessation services. Therefore, this study aimed to assess the cost-effectiveness of these multidisciplinary services compared to the usual care among COPD patients in Thailand from a societal perspective. METHODS We conducted a CEA from a societal perspective using a Markov model to simulate lifetime costs and quality-adjusted life years (QALYs) gained of each smoking cessation intervention over the patient’s lifetime. We derived the effectiveness of the smoking cessation services from a multicenter, longitudinal study of smoking cessation services in Thailand and estimated the natural quit rate, transition probabilities, health utility, and cost data from the published literature. Costs and outcomes were discounted at 3%. Sensitivity analyses were performed. RESULTS Compared to the usual care, FAH-SAI clinics were associated with higher costs (4,207THB (US$133)) and improved QALYs (0.11), with an incremental cost-effectiveness ratio of 37,675THB/QALY(US$1,187/QALY). The effectiveness of FAH-SAI clinics was a key driver of the cost-effectiveness results. At the willingness-to-pay (WTP) threshold of 160,000THB (US$5,042) per QALY gained, the probability of being cost-effective was 96.5%. CONCLUSIONS FAH-SAI clinics were cost-effective under Thailand’s WTP threshold. Our results could inform policymakers in allocating resources to support smoking cessation services for COPD patients in Thailand.

We review medical economics literature presented at the 2023 annual AEA-ASSA convention, the largest gathering of economists worldwide. Pharmacoeconomic papers addressed a wide range of issues, including gender and racial gaps in clinical trials, hospital credit financing, drug rebates, covid-19 vaccine equality, and the opioid epidemic. Yet, they had some common identifiable themes. We examine them in the context of the “twin towers” of biopharmaceutical innovation: discovery and commercialization. Implementation outcomes and relative success of innovative solutions — whether in terms of products and services, structural design and arrangements, or policies — depend on how adequately they respond to questions and challenges that arise in drug discovery and commercialization, and who gains from them. That innovation’s beneficiaries might not equally gain from its intended advantages is another unifying theme in the reviewed literature. Against this backdrop, biopharmaceutical innovation can breed new challenges and opportunities. And health policy can perform a critical, leveling function that reduces cost, increases access, and ensures quality of biopharmaceutical solutions.

Background Postoperative atrial fibrillation (POAF) is one of the most common complications following cardiac surgery. POAF is associated with increased hospitalization costs, but its long-term economic burden is not well defined. Objective To assess 30-day and 1-year incremental healthcare resource utilization (HRU) and costs associated with POAF in the United States (US). Methods This retrospective cohort study used claims data from the IBM Watson MarketScan database. A cohort of US adults aged 55-90 years who underwent open-heart surgery between January 1, 2017 and December 31, 2018 was used to compare patients who experienced POAF versus patients who did not (controls). The outcomes of interest were incremental HRU and costs, which were assessed during the index hospitalization and 30-day and 1-year postdischarge time periods. Inverse probability weighting was used to adjust for differences in baseline characteristics. Results A total of 8,020 patients met the study inclusion criteria with 5,765 patients in the control cohort (mean age, 63.4 years) and 2,255 patients in the POAF cohort (mean age, 65.8 years). After adjustment, patients with POAF had an index hospitalization that was 1.9 days longer (99% CI, 1.3-2.4 days; P < 0.001) and cost $13,919 more (99% CI, $2,828-$25,011; P < 0.001) than for patients without POAF. POAF patients also had significantly higher HRU at 30 days and 1 year postdischarge with incremental costs of $4,649 (99% CI, $1,479-$7,819; P < 0.001) and $10,671 (99% CI, $2,407-$18,935; P < 0.001), respectively. Conclusion POAF following open-heart surgery poses a significant economic burden up to 1 year postdischarge.

Aims French guidelines for the management of non-muscle-invasive bladder cancer recommend that blue-light cystoscopy should be used in patients where the risk of missing residual tumour is highest. Despite evidence for its cost effectiveness, budgetary concerns have limited uptake in France. The aim of this analysis was to model the cost-consequences of adopting the recommendations in a French urology unit. Materials and methods A budget impact model was developed in Excel, using a decision tree approach derived from guidelines issued by L’Academie franҫaise d’urologie. Risk profiles were derived from an analysis of studies using white-light cystoscopy; estimates for the impact of blue-light cystoscopy were derived from a published Cochrane Review. Costs were based on published tariff prices from L’Agence Technique de L’Information sur L’Hospitalisation. The model allowed results to be tailored to activity levels and projected blue-light usage in the chosen urology unit. Results Two scenarios were evaluated, based on a three-year time horizon. Full implementation of all recommendations within a large public hospital was estimated to yield incremental costs of €269 per procedure (∼10% increase overall); a more targeted approach within a smaller private hospital yielded incremental costs of €133 per procedure (5% increase overall). Limitations The basis of the model is a change in the time to first recurrence. There are no data available for subsequent recurrences or progression, both of which could have an influence on expenditure. Secondly, recurrence rates for blue-light cystoscopy were not specifically available for each patient group identified in the guidelines: extrapolation of data may have resulted in bias. Finally, the data were derived from clinical trials, which may not be generalisable to real-world clinical practice. Conclusions The model has shown that the additional expenditure required to implement blue-light cystoscopy is modest and not disproportionate to the overall cost of care.

Background Minimally invasive surgical therapies, such as water vapor thermal therapy (WVTT) and prostatic urethral lift (PUL), are typically second-line options for patients in whom medical management (MM) failed but who are unwilling or unsuitable to undergo invasive transurethral resection of the prostate (TURP). However, the incremental cost-effectiveness of WVTT or PUL as first- or second-line therapy is unknown. We evaluated the incremental cost-effectiveness of alternative first- and second-line treatments for patients with moderate-to-severe benign prostatic hyperplasia (BPH) in Singapore to help policymakers make subsidy decisions based on value for money. Methods We considered six stepped-up treatment strategies, beginning with MM, WVTT, PUL or TURP. In each strategy, patients requiring retreatment advance to a more invasive treatment until TURP, which may be undergone twice. A Markov cohort model was used to simulate transitions between BPH severity states and retreatment, accruing costs and quality-adjusted life-years (QALYs) over a lifetime horizon. Results In moderate patients, strategies beginning with MM had similar cost and effectiveness, and first-line WVTT was incrementally cost-effective to first-line MM (33,307 SGD/QALY). First-line TURP was not incrementally cost-effective to first-line WVTT (159,361 SGD/QALY). For severe patients, WVTT was incrementally cost-effective to MM as a first-line treatment (30,133 SGD/QALY) and to TURP as a second-line treatment following MM (6877 SGD/QALY). TURP was incrementally cost-effective to WVTT as a first-line treatment (48,209 SGD/QALY) in severe patients only. All pathways involving PUL were dominated (higher costs and lower QALYs). Conclusion Based on the common willingness-to-pay threshold of SGD 50,000/QALY, this study demonstrates the cost-effectiveness of WVTT over MM as first-line treatment for patients with moderate or severe BPH, suggesting it represents good value for money and should be considered for subsidy. PUL is not cost-effective as a first- nor second-line treatment. For patients with severe BPH, TURP as first-line is also cost-effective.

ABSTRACT Introduction Transfemoral access (TFA) is the primary access approach for neurointerventional procedures. Transradial access (TRA) is established in cardiology due to its lower complications, yet, it is at its early stages in neuroprocedures. This study performs an early exploration of the economic impact associated with the introduction of TRA in diagnostic and therapeutic neuroprocedures from the Spanish NHS perspective. Methods A economic model was developed to estimate the cost and clinical implications of using TRA compared to TFA. Costs considered access-related, complications and recovery time costs obtained from local databases and experts' inputs. Clinical inputs were sourced from literature. A panel of eight experts from different Spanish hospitals, validated or adjusted the values based on local experience. Hypothetical cohorts of 10,000 and 1,000 patients were considered for diagnostic and therapeutic neuroprocedures respectively. Deterministic sensitivity analysis was performed. Results TRA in diagnostic procedures was associated with lower costs with savings ranging between €486-€157 depending on the TFA recovery time considered. TRA is estimated to lead to 158 fewer access-site complications. In therapeutic procedures, TRA resulted in 76.4 fewer complications and was estimated to be cost-neutral with an incremental cost of €21.56 per patient despite recovery times were not included for this group. Variation of the parameters in the sensitivity analysis did not change the direction of the results. Limitations Clinical data was obtained from literature validated by experts therefore results generalizability is limited. In therapeutic neuroprocedures, there is an experience imbalance between approaches and recovery times were not included hence the total impact is not fully captured. Conclusions The early economic model suggests that implementing TRA is associated with reduced costs and complications in diagnostic procedures. In therapeutic procedures, TRA lead to fewer complications and it is estimated to be cost-neutral, however its full potential still needs to be quantified.
