Estimating the population health and economic impacts of introducing a pneumococcal conjugate vaccine in Malaysia- an economic evaluation

Pneumococcal disease is a potentially fatal bacterial infection that is vaccine-preventable. Malaysia has yet to adopt a pneumococcal conjugate vaccine (PCV) into its national immunization program (NIP). In 2016, pneumonia was the 3rd leading cause of death in children under five in Malaysia, accounting for 3.8% of under-five deaths. Introducing a pneumococcal conjugate vaccine (PCV) is an effective strategy to reduce the disease burden. This study used a decision-analytic model to assess the potential impacts of introducing the available PCVs (13-valent and 10-valent) in Malaysia. Epidemiological and costs inputs were sourced from published literature. For each vaccination program, health outcomes and associated healthcare costs were estimated. The scenarios of initiating PCV13 vs. PCV10 and the status quo (no pneumococcal vaccine) were compared. Serotype trends of Finland and the U.K. were used to model the clinical impacts of PCV10 and PCV13 respectively. The base-case analysis used a societal perspective over a 5-year time horizon. Compared with PCV10, PCV13 was projected to avert an additional 190,628 cases of pneumococcal disease and 1126 cases of death. The acquisition of PCV13 was estimated to cost an incremental US$89,904,777, offset by a cost reduction of -US$250,219,914 on pneumococcal disease-related medical care and lost productivity. PCV13 demonstrated a higher cost-saving potential over PCV10. Compared with no vaccination, PCV13 was estimated as cost-saving. Results were robust across a series of sensitivity analyses. The introduction of PCV13 in a NIP was estimated to reduce a significant burden of disease and to be a cost-saving for the Malaysian health system

Cost-effectiveness of alternative first- and second-line treatments for benign prostatic hyperplasia in Singapore

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. 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. 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 (6,877 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). 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 first- nor second-line treatment. For patients with severe BPH, TURP as first-line is also cost-effective.</p
