Costs of Workplace Productivity Loss in Patients With Fibrotic Interstitial Lung Disease.

BACKGROUND: Fibrotic interstitial lung diseases (ILDs) are highly morbid chronic disorders that frequently occur in working age individuals. The goal of this study was to determine workplace productivity loss, its determinants, and its estimated costs in patients with fibrotic ILD. METHODS: Patients with idiopathic pulmonary fibrosis, chronic hypersensitivity pneumonitis, idiopathic nonspecific interstitial pneumonia, or unclassifiable ILD were identified from the six-center Canadian Registry for Pulmonary Fibrosis (CARE-PF). The Work Productivity and Activity Impairment questionnaire was used to determine health-related productivity loss. Independent predictors of low workplace productivity were identified by using multivariate regression. Patient data were compared with Canadian population census data. The average productivity loss (hours per week) and the individual's hourly wage were used to estimate the costs of productivity loss. RESULTS: Of 650 eligible patients, 148 (23%) were employed. Productivity loss was reported by 55% of employed patients with an average productivity loss of 7.8 ± 0.9 h per week (2.3 ± 0.6 h per week related to absenteeism and 5.5 ± 0.6 h per week related to presenteeism). Employment among patients with ILD aged 25 to 54 years was 23% lower than the age- and sex-matched general Canadian population (60% vs 83%; P < .001). Employment among patients with ILD aged ≥ 55 years was 18% lower than in the age- and sex-matched population (20% vs 38%; P < .001). Dyspnea and cough were independent predictors of workplace productivity loss. Estimated annual costs of productivity loss were 11,610 Canadian dollars per employee with ILD. CONCLUSIONS: Workplace productivity loss is common in fibrotic ILD, strongly correlated with symptom severity, and associated with significant cost.

Benefits of quitting smoking on work productivity and activity impairment in the United States, the European Union and China.

BACKGROUND: Smoking has important health and economic consequences for individuals and society. This study expands the understanding of work-related burden associated with smoking and benefit of smoking cessation across the US, European Union (EU) and China using large-scale, representative survey methodology. METHODS: Data utilised the 2013 National Health and Wellness Survey in United States (US), EU5 (UK, France, Germany, Italy, and Spain) and China. Working-aged respondents 18-64 were used in the analyses (US N=58 500; EU5 N=50 417; China N=17 987) and were categorised into: current smokers, trying to quit, former smokers and never smokers. Generalised linear models controlling for demographics and health characteristics examined the relationship of smoking status with work productivity and activity impairment (WPAI-GH). The WPAI-GH measures were: absenteeism, presenteeism, overall work impairment, and activity impairment. Separately, current smokers were compared with those who quit 0-4, 5-10 and 11 or more years ago on WPAI-GH end-points. RESULTS: Current smokers reported greater absenteeism in the US and China and greater presenteeism, overall work impairment, and activity impairment than former and never smokers across the three regions. Those who quit even 0-4 years ago demonstrated lower absenteeism, presenteeism, and activity impairment in China and lower presenteeism, overall work impairment, and activity impairment in the US and EU5. CONCLUSIONS: Smoking was associated with significant work productivity loss in the US, EU5 and China. The results suggest that quitting benefits extend to work productivity rapidly after cessation, serving to further encourage and promote the implementation of workplace cessation programs.

Effect of Continued Medical Therapy on Productivity Costs for Refractory Chronic Rhinosinusitis.

IMPORTANCE: It is estimated that lost productivity related to chronic rhinosinusitis (CRS) costs society in excess of $13 billion per year in the United States. Given this tremendous cost to society, it is important to evaluate the effect of current interventions on improving this productivity loss. OBJECTIVE: To define the change in productivity costs in patients with refractory CRS who select continued medical therapy. DESIGN, SETTING, AND PARTICIPANTS: Observational cohort study. Thirty-eight patients with a guideline-based diagnosis of CRS whose initial appropriate medical therapy failed were enrolled from 4 tertiary-level rhinology clinics. The study was conducted from December 6, 2010, to April 23, 2013, and data analysis was performed from December 6, 2010, to June 1, 2015. INTERVENTIONS: Continued medical therapy for CRS. MAIN OUTCOMES AND MEASURES: The human capital approach was applied to quantify productivity costs. Absenteeism, presenteeism, and lost leisure time were quantified to define annual lost productive time, which was measured at enrollment (baseline) and at a minimum of 6 months after treatment. Lost productive time was monetized using the annual daily wage rates obtained from the 2012 US National Census and the 2013 US Department of Labor statistics. RESULTS: Thirty-eight patients with refractory CRS who selected continued medical therapy had a mean (SD) baseline annual productivity cost of $3464 ($4900) per patient. After continued medical therapy for a mean of 12.8 (4.8) months, productivity costs were $2730 ($3720) (before vs after continued medical therapy productivity cost, P = .74). Mean annual absenteeism was reduced from 5 (12) days to 2 (8) days (P = .02). Mean annual presenteeism (17 [27] days reduced to 15 [23] days; P = .93) and mean annual household days lost (7 [7] days reduced to 6 [6] days; P = .51) were maintained at baseline levels. There were no significant differences in productivity outcomes based on endoscopy, the 22-item Sinonasal Outcome Test score, age, or polyp status (all P ≥ .11). CONCLUSIONS AND RELEVANCE: Patients with refractory CRS often make treatment decisions based on the degree of quality-of-life and productivity impairment. Outcomes from this study suggest that productivity in patients with refractory CRS who have minor reductions in baseline productivity can remain stable with continued medical therapy. Physicians can use this information to inform appropriate patients with CRS of their expected outcomes from continued medical therapy.
