Background: If the most evidence-based and effective smoking cessation apps are not selected by smokers wanting to quit, their potential to support cessation is limited.

Objective: This study sought to determine the attributes that influence smoking cessation app uptake and understand their relative importance to support future efforts to present evidence-based apps more effectively to maximize uptake.

Methods: Adult smokers from the United Kingdom were invited to participate in a discrete choice experiment.

Article Synopsis
  • Cystic fibrosis (CF) is a complex chronic condition that requires ongoing treatment, and this review examines various ways researchers have measured the treatment burden faced by individuals with CF.
  • A total of 17 studies were reviewed, highlighting both subjective measures (like questionnaires) and objective measures (such as treatment time and costs) to understand treatment burden, with most studies emphasizing treatment time.
  • The findings suggest that no single measure can capture the full scope of treatment burden; therefore, combining subjective and objective measures may better reflect the diverse aspects affecting individuals with CF.

Background: The EQ-5D is the recommended measure to capture health-related quality of life (HRQoL), recognised for use in health technology appraisal bodies. In order to assess whether it is appropriate to use the EQ-5D for making decisions about the cost-utility of treatments in cystic fibrosis (CF), this study assesses the performance of the EQ-5D-5L in adults and adolescents with CF.

Method: This was a cross-sectional observational survey study of patients with CF attending a single large CF centre.

Choice-based preference elicitation methods such as the discrete choice experiment (DCE) present hypothetical choices to respondents, with an expectation that these hypothetical choices accurately reflect a 'real world' health-related decision context and that consequently the choice data can be held to be a true representation of the respondent's health or treatment preferences. For this to be the case, careful consideration needs to be given to the format of the choice task in a choice experiment. The overarching aim of this paper is to highlight important aspects to consider when designing and 'setting up' the choice tasks to be presented to respondents in a DCE.

Background: Asset-based approaches (ABAs) tackle health inequalities by empowering people in more disadvantaged communities, or targeted populations, to better utilise pre-existing local community-based resources. Using existing resources supports individuals to better manage their own health and its determinants, potentially at low cost. Targeting individuals disengaged with traditional service delivery methods offers further potential for meaningful cost-savings, since these people often require costly care.

Background: Public preferences are an important consideration for priority-setting. Critics suggest preferences of the public who are potentially naïve to the issue under consideration may lead to sub-optimal decisions. We assessed the impact of information and deliberation a Citizens' Jury (CJ) or preference elicitation methods (Discrete Choice Experiment, DCE) on preferences for prioritizing access to bariatric surgery.

Background: There is growing evidence regarding the potential of closed incision negative pressure wound therapy (ci-NPWT) to prevent surgical site infections (SSIs) in healing wounds by primary closure following a caesarean section (CS).

Aim: To assess the cost-effectiveness of ci-NPWT compared to standard dressings for prevention of SSI in obese women giving birth by CS.

Materials And Methods: Cost-effectiveness and cost-utility analyses from a health service perspective were undertaken alongside a multicentre pragmatic randomised controlled trial, which recruited women with a pre-pregnancy body mass index ≥30 kg/m giving birth by elective/semi-urgent CS who received ci-NPWT (n = 1017) or standard dressings (n = 1018).

Background: There is a growing consensus that the perspective of the patient should be considered in the evaluation of novel interventions.

Research Question: What treatment outcomes matter to people with cystic fibrosis (CF), and what trade-offs would they make to realize these outcomes?

Study Design And Methods: Adults attending a specialist CF center were invited to complete an online discrete choice experiment (DCE). The DCE required participants to evaluate hypothetical CF treatment profiles, defined by impact on lung function, pulmonary exacerbations, abdominal symptoms, life expectancy, quality of life, inhaled medicine usage, and physiotherapy requirement.

Purpose: Cost-effectiveness evaluations of interventions require health utility data. However, in medical conditions, such as aromatic L-amino acid decarboxylase (AADC) deficiency, this presents problems due to the rarity of the disease. The study aim therefore was to employ a discrete choice experiment (DCE) to generate health utilities for AADC deficiency.

Background: Prophylactic foam border dressings are recommended for high-risk patients in addition to standard pressure injury prevention protocols despite limited high-quality evidence regarding their effectiveness. This protocol describes the process evaluation that will be undertaken alongside a multisite randomised controlled trial investigating the clinical and cost-effectiveness of these dressings in reducing hospital-acquired sacral pressure injury incidence.

Methods: This theory informed parallel process evaluation using qualitative and quantitative methods will be undertaken in medical and surgical units.

Understanding the preferences of potential users of digital health products is beneficial for digital health policy and planning. Stated preference methods could help elicit individuals' preferences in the absence of observational data. A discrete choice experiment (DCE) is a commonly used stated preference method-a quantitative methodology that argues that individuals make trade-offs when engaging in a decision by choosing an alternative of a product or a service that offers the greatest utility, or benefit.

Purpose: Deriving health utilities for rare medical conditions such as aromatic L-amino acid decarboxylase (AADC) deficiency poses challenges. The rarity of AADC deficiency and the fact that this genetic condition often presents in very young children means that robust utility values cannot be derived from the child or their parent/caregiver. Alternative approaches, eg, discrete choice experiments (DCE), are required in order to provide health utilities.
