Interest in using patient preference (PP) data alongside traditional economic models in health technology assessment (HTA) is growing, including using PP data to quantify non-health benefits. However, this is limited by a lack of standardised methods. In this article, we describe a method for using discrete choice experiment (DCE) data to estimate the value of non-health benefits in terms of quality-adjusted survival equivalence (QASE), which is consistent with the concept of value prevalent among HTA agencies.

Objectives: Nirmatrelvir/ritonavir (NMV/r) is an orally administered antiviral indicated for the outpatient treatment of patients with mild-to-moderate COVID-19 at high risk for disease progression to severe illness. We estimated the cost-effectiveness of NMV/r versus best supportive care for patients with mild-to-moderate COVID-19 at high risk for progression to severe illness from a US health sector perspective.

Methods: A cost-effectiveness model was developed using a short-term decision-tree (1 year) followed by a lifetime 2-state Markov model (alive and dead).

Article Synopsis
  • In Poland, Lyme borreliosis (LB) has been under public health surveillance since 1996, with a significant increase in reported cases from 2015 to 2016 and stable numbers until 2019, totaling 94,715 cases during that period.
  • The study found that women made up a majority of cases (55.7%), with the highest incidence found in those over 50, especially in the 65-69 age group, and most cases occurred in the second half of the year.
  • Geographic analysis revealed higher incidence rates in eastern and northeastern Poland, indicating a need for targeted prevention strategies due to large variations in incidence across regions.

We assessed efficacy and effectiveness of pharmacological and nonpharmacological interventions in improving symptom control, functional exercise capacity and quality of life (QoL) in people living with fibrotic interstitial lung disease (ILD). We summarised evidence from three previous reviews (to June 2014) and conducted an updated search of nine databases and grey literature (2011-2019) (registration: CRD42017065933) for prospective studies of interventions aimed to alleviate symptoms, improve QoL or functional exercise capacity in fibrotic ILD. Data were synthesised through narrative synthesis or meta-analysed as appropriate.

Background: Disability is an increasingly important health-related outcome to consider as more individuals are now aging with Human Immunodeficiency Virus (HIV) and multimorbidity. The HIV Disability Questionnaire (HDQ) is a patient-reported outcome measure (PROM), developed to measure the presence, severity and episodic nature of disability among adults living with HIV. The 69-item HDQ includes six domains: physical, cognitive, mental-emotional symptoms and impairments, uncertainty and worrying about the future, difficulties with day-to-day activities, and challenges to social inclusion.

  • Rehabilitation for multiple sclerosis (MS) is effective and shows significant improvement in patient dependency and functional independence post-treatment.
  • A study of 1,007 patients in England found that more dependent individuals experienced the greatest reductions in ongoing care costs after rehabilitation.
  • Specialist inpatient rehabilitation is concluded to be cost-efficient, particularly for high-dependency patients, yielding both improved outcomes and savings in care expenses.

Introduction: Provision of palliative care is inequitable with wide variations across conditions and settings in the UK. Lack of a standard way to classify by case complexity is one of the principle obstacles to addressing this. We aim to develop and validate a casemix classification to support the prediction of costs of specialist palliative care provision.

Background: High symptom burden is common in long-term care residents with dementia and results in distress and behavioral challenges if undetected. Physicians may have limited time to regularly examine all residents, particularly those unable to self-report, and may rely on reports from caregivers who are frequently in a good position to detect symptoms quickly. We aimed to identify proxy-completed assessment measures of symptoms experienced by people with dementia, and critically appraise the psychometric properties and applicability for use in long-term care settings by caregivers.

Palliative care is a public health concern, because the problems faced by patients and their families represent a substantial burden of illness and cost to the society that is likely to increase markedly in the future as the world's population continues to age. There are also inequities in access to palliative care and continued unmet need. There is evidence to support palliative care services, but not yet enough information on the cost-effectiveness of many specific treatments/interventions.
