The Cost-Effectiveness of Adjunctive Lifestyle Interventions for the Management of Cancer: A Systematic Review

OBJECTIVE

There is a paucity of papers synthesizing the cost-effectiveness (CE) of lifestyle interventions to support cancer patients, and the synthesis papers available have used analytic methods that do not permit easy comparison between studies. We therefore evaluated the CE of adjunctive lifestyle interventions compared with usual care.

METHODS

A systematic literature search of Scopus, MEDLINE, EMBASE, PsycINFO, CINAHL and the Cochrane Library databases was conducted from database inception until June 2021. Eligible studies were economic evaluations from randomised controlled trials or modelled economic evaluations that recruited subjects with a confirmed diagnosis of cancer and were allocated to a lifestyle intervention as an adjunct or supportive treatment, or usual care. Studies were excluded if there was no cost-effectiveness analysis or if costs were identified but not related back to measures of effectiveness. CE of the included interventions was recalculated, adjusting for key differences (with respect to absolute resource costs and timing) between the broad range of study settings and a common 'target' setting. All CE data were converted into incremental net monetary benefit using a common cost-effectiveness threshold to facilitate comparison. The quality of the studies was evaluated for risk of bias using the ECOBIAS check list.

RESULTS

Nine studies were included in our review. Seven studies investigated the benefits of physical exercise in combination with cancer treatment and two studies investigated the combination of exercise and psychosocial counselling alongside cancer treatment. Six studies with an exercise intervention reported larger quality-adjusted life year (QALY) gains compared with usual care and when cost per QALY gained was considered, three of the interventions were cost effective. One of the two interventions combining exercise with psychosocial counselling was cost effective. All studies were considered of good quality but all had some limitations.

CONCLUSIONS

The evidence to support the cost effectiveness of lifestyle interventions in patients with cancer is mixed with four of the nine interventions found to be cost effective and two remaining cost effective when uncertainty was taken into account. Sensitivity analysis showed the influence of the CE threshold on the results, highlighting the importance of selecting a CE threshold that is appropriate to the setting.

The differences of the economic losses due to presenteeism and treatment costs between high-stress workers and non-high-stress workers using the stress check survey in Japan

OBJECTIVES

This study sought to examine differences in the economic losses due to presenteeism and costs of medical and dental treatment between high-stress workers and non-high-stress workers using the stress check survey.

METHODS

We conducted a cross-sectional study from April 1, 2018 to March 31, 2019 in a pharmaceutical company. High-stress workers were classified with the Brief Job Stress Questionnaire using two methods: the sum method and the score converted method. The incidence of presenteeism and its costs were determined using a questionnaire. The costs of medical and dental treatment were calculated according to claims. We compared the costs between high-stress and non-high-stress workers using Wilcoxon's rank-sum test.

RESULTS

Of 3910 workers, 6.3% were classified as high-stress using the sum method and 6.6% were classified as high-stress using the score converted method. The costs associated with presenteeism and medical treatment among high-stress workers were higher than the costs among non-high-stress workers, whereas the costs associated with dental treatment were not.

CONCLUSIONS

To motivate employers to improve stressful work environments, it is recommended that presenteeism measurement items be added to the stress check survey, and that the methods used in this study be used to calculate the loss associated with high-stress workers in Japanese companies. However, we must be careful in interpreting absolute presenteeism loss amounts because they are poorly reliable and valid.

Impacts of physical late effects on presenteeism in childhood cancer survivors

BACKGROUND

Many childhood cancer survivors (CCSs) experience physical late effects related to their cancer types and treatment modalities. Physical late effects are an important factor in various occupational outcomes among CCSs. However, the relationship between physical late effects and presenteeism has remained unclear. This study aimed to estimate the impacts of physical late effects on presenteeism among employed CCSs.

METHODS

Childhood cancer survivors replied to a questionnaire regarding presenteeism, and their attending physicians assessed their physical late effects between September 2014 and December 2015. The Work Limitations Questionnaire was used to measure presenteeism. Propensity score analysis and a generalized linear model were used to adjust covariates related to physical late effects and / or presenteeism.

RESULTS

Of the 125 questionnaires distributed, 114 were returned. The data from 61 employed CCSs were analyzed. After controlling for covariates by propensity score analysis and generalized linear model, there were no significant differences in presenteeism between employed CCSs with either no or single physical late effects. However, employed CCSs with multiple physical late effects reported higher scores in Output (Estimate = 9.3, P = 0.041), Physical Demands (Estimate = 12.2, P = 0.020), and Productivity Loss scores (Estimate = 2.4, P = 0.045) on the Work Limitations Questionnaire than employed CCSs with no physical late effects.

CONCLUSIONS

Employed CCSs with multiple physical late effects were at an increased risk for presenteeism. Healthcare and social welfare systems should be established to provide vocational assistance for CCSs after being employed to alleviate presenteeism.

Impact of nutrition interventions and dietary nutrient density on productivity in the workplace

The global spread of diet-related noncommunicable diseases represents a threat to public health and national economies alike. The elimination of poverty and the eradication of hunger, two key United Nations Sustainable Development Goals, cannot be accomplished without a well-nourished labor force. Easy access to low-cost diets that are energy dense but nutrient poor has resulted in hidden hunger, in which micronutrient deficiencies coexist with obesity or overweight. Workplace interventions in low- and middle-income countries have addressed nutrient adequacy and micronutrient deficiencies, often using fortified foods. Workplace interventions in high-income countries have largely focused on weight loss, smoking cessation, stress reduction, and physical activity. Even though improvement of productivity may have been the ultimate goal, relatively few interventions in high-income countries have explored the likely impact of improved dietary nutrient density on workplace performance. Given that optimal nutrition benefits both physical and mental health, interventions to improve diet quality ought to have a measurable impact on the productivity of the labor force. The present review examines the evidence linking workplace dietary interventions with workplace productivity measures.
