The Societal Impact of Inclisiran in England: Evidence From a Population Health Approach

OBJECTIVES

As first-in-class cholesterol-lowering small interfering ribonucleic acid, inclisiran provides effective reductions in low-density lipoprotein-cholesterol to achieve better cardiovascular (CV) health. We estimate the health and socioeconomic effects of introducing inclisiran according to a population health agreement in England.

METHODS

Building on the inclisiran cost-effectiveness model, a Markov model simulates health gains in terms of avoided CV events and CV deaths because of add-on inclisiran treatment for patients aged 50 years and older with pre-existing atherosclerotic CV disease. These are translated into socioeconomic effects, defined as societal impact. To that end, we quantify avoided productivity losses in terms of paid and unpaid work productivity and monetize them according to gross value added. Furthermore, we calculate value chain effects for paid work activities, drawing on value-added multipliers based on input-output tables. The derived value-invest ratio compares avoided productivity losses against the increased healthcare costs.

RESULTS

Our results show that 138 647 CV events could be avoided over a period of 10 years. The resulting societal impact amounts to £8.17 billion, whereas additional healthcare costs are estimated at £7.94 billion. This translates into a value-invest ratio of 1.03.

CONCLUSIONS

Our estimates demonstrate the potential health and socioeconomic value of inclisiran. Thereby, we highlight the importance to treat CVD and illustrate the impact that a large-scale intervention can have on population health and the economy.

Productivity losses associated with cardiovascular disease: a systematic review

INTRODUCTION

People with cardiovascular disease (CVD) often require time off work to recover from illness or surgery; for example, following a myocardial infarction (MI) or stroke. These individuals incur income losses, work-related productivity is reduced for employers, and output is reduced for the wider economy. Productivity impacts to the economy also arise due to CVD-related mortality. Areas covered: A systematic literature review was conducted to identify and collate studies that report the magnitude of work-related productivity losses associated with CVD generally or specific cardiovascular (CV) events or conditions (coronary heart disease, MI, stroke, transient ischemic attack, angina, heart failure, peripheral artery disease, coronary revascularization). The search was conducted using Medline, Embase, the Cochrane Library, and Google to find studies published from January 2004 to January 2015. In total, 60 studies were identified, including 20 studies conducted in the USA, 25 studies conducted in Europe, and 18 studies conducted in other countries (three studies were conducted in multiple regions). The studies differed by the scope of losses assessed (absenteeism, presenteeism, early retirement, premature mortality) and CVD conditions/events included. Studies reported either average patient or population losses, and generally used a human capital rather than friction cost method. Outcomes were standardized and adjusted to 2015 US dollars where possible. Expert commentary: The review demonstrates that CVD imposes substantial morbidity- and mortality-related productivity costs. The studies identified in the review may be used to inform and populate societal economic evaluations in CVD, with the most appropriate source study being that most closely matching the context of the evaluation.

Factors influencing return-to-work after cerebrovascular disease: the importance of previous cardiovascular risk

BACKGROUND

The role of prior cardiovascular risk (CVR) in the multifactorial process of returning to work after a cerebrovascular event has not been adequately investigated. Therefore, the objective of the present study was to analyse the association between previous CVR level, cardiovascular risk factors (CVRFs) and return-to-work (RTW) following cerebrovascular disease.

DESIGN

This was a prospective observational study.

METHODS

We analysed a cohort of 348 patients who had experienced an episode of cerebrovascular disease-related work absence. These individuals were selected from the ICARIA study (Ibermutuamur CArdiovascular RIsk Assessment). Global CVR was assessed using the SCORE system. We investigated the association between demographics, work-related variables, CVRFs and RTW following a cerebrovascular event.

RESULTS

We found that a total of 254 individuals (73.0%; 95% CI: 68.3-77.7) returned to work after cerebrovascular disease. Also, we observed a median loss of 12 working years due to disability. Moreover, adjusting for potential confounders revealed that low CVR level and the absence of the following CVRFs was associated with a higher likelihood of RTW: low vs moderate-to-high CVR level (OR: 2.55; 95% CI: 1.42-4.57), no hypertension before stroke (OR: 1.95; 95% CI: 1.11-3.41), non-smoker status (OR: 2.26; 95% CI: 1.30-3.93) and no previous diabetes (OR: 2.46; 95% CI: 1.26-4.79).

CONCLUSIONS

Low CVR, along with the absence of several CVRFs, can be used to predict RTW rates following cerebrovascular events. Therefore, controlling hypertension, tobacco consumption and diabetes might contribute to the effectiveness of multidisciplinary rehabilitation and/or secondary/tertiary prevention programs for cerebrovascular disease.

A Q-Methodology Study of Patients' Subjective Experiences of TIA

Background. An expanding body of research has focused on a range of consequences of TIA. However, no work has been conducted on the patient's subjective experience of TIA. Aim. To capture patients' first-hand experiences of TIA. Method. Using Q-methodology which employs both qualitative and quantitative approaches, 39 statements relating to the clinical, physical, affective, and psychological impact of TIA were distilled from the literature and from patient narratives. Consistent with conventional Q-methodology, a purposive sample of twentythree post-TIA patients sorted these statements into a normally-distributed 39-cell grid, according to the extent to which each represented their experience of TIA. Results. Casewise factoranalysis was conducted on the sorted statements. Eight factors emerged which were labelled: lack of knowledge/awareness of TIA; life impact; anxiety; interpersonal impact; depression; physical consequences; cognitive avoidance/denial; constructive optimism. Conclusions. Five of the eight factors confirmed existing research on the impact of TIA, but three new issues emerged: deep-seated anxiety, denial and constructive optimism. The emerging perspectives highlight areas to target in the management of TIA and could inform health education messages, patient information, individualised caremanagement, and enhancement of coping strategies. With development, the findings could be used as a basis for psychometric risk assessment of TIA patients.
