Objectives: It has been estimated that vaccines can accrue a relatively large part of their value from patient and carer productivity. Yet, productivity value is not commonly or consistently considered in health economic evaluations of vaccines in several high-income countries. To contribute to a better understanding of the potential impact of including productivity value on the expected cost-effectiveness of vaccination, we illustrate the extent to which the incremental costs would change with and without productivity value incorporated.

The global invasive meningococcal disease (IMD) landscape changed considerably during the COVID-19 pandemic, as evidenced by decreased incidence rates due to COVID-19 mitigation measures, such as limited social contact, physical distancing, mask wearing, and hand washing. Vaccination rates were also lower during the pandemic relative to pre-pandemic levels. Although policymakers may have shifted their focus away from IMD vaccination programs to COVID-19 vaccination programs, strong arguments support implementation and prioritization of IMD vaccination programs; IMD cases have increased in some countries and IMD rates may even have exceeded pre-pandemic levels.

Objectives: It is widely argued that the value of meningococcal vaccination extends beyond the narrow value elements traditionally considered in health technology assessment. Nevertheless, measuring broader value presents challenges, whereas assessment methods and outcomes vary widely. This article investigates the extent to which the broader value of meningococcal vaccination is recognized, considering the available evidence and decision maker's methodological ability and willingness.

Objective: The aims of this study were to evaluate health outcomes and the economic burden of hospitalized COVID-19 patients in the United States.

Methods: Hospitalized patients with a primary or secondary discharge diagnosis code for COVID-19 (ICD-10 code U07.1) from 1 April to 31 October 2020 were identified in the Premier Healthcare COVID-19 Database.

Introduction: To evaluate the expected impact of the Algeria national immunization program (NIP) and potential impact for a Tunisia NIP, this study assessed the public health and economic value of vaccination, through a cost-effectiveness analysis, for a PCV13 or PCV10 NIP, compared with no vaccination.

Methods: A decision-analytic model was programmed in Microsoft Excel™ and adapted to evaluate the clinical and economic outcomes of PCV vaccination. Assuming a steady state, the model estimated invasive pneumococcal disease (IPD; bacteremia and meningitis), all-cause pneumonia (inpatient and outpatient), and all-cause otitis media cases as well as the associated costs from a payer perspective.

Objectives: To evaluate potential costs and savings from implementing an evaluation tool that uses bedside review of antibiotic use and infection management to assess whether patients with infections in acute medical and surgical wards could have their antibiotic regimen changed and be safely managed out of hospital.

Methods: The tool was implemented in 30 acute wards in five UK hospital trusts. Data were collected on demographic variables, diagnosis, social situation, hospital stay and all current antibiotic prescribing for 291 patients.
