<p>Comparable estimates of the heat-related work productivity loss (WPL) in different countries over the world are difficult partly due to the lack of exact measures and comparable data for different counties. In this study, we analysed 4363 responses to a global online survey on the WPL during heat waves in 2016. The participants were from both developed and developing countries, facilitating estimates of the heat-related WPL across the world for the year. The heat-related WPL for each country involved was then deduced for increases of 1.5, 2, 3 and 4 °C in the global mean surface temperature under the representative concentration pathway scenarios in climate models. The average heat-related WPL in 2016 was 6.6 days for developing countries and 3.5 days for developed countries. The estimated heat-related WPL was negatively correlated with the gross domestic product per capita. When global surface temperatures increased by 1.5, 2, 3 and 4 °C, the corresponding WPL was 9 (19), 12 (31), 22 (61) and 33 (94) days for developed (developing) countries, quantifying how developing countries are more vulnerable to climate change from a particular point of view. Moreover, the heat-related WPL was unevenly distributed among developing countries. In a 2°C-warmer world, the heat-related WPL would be more than two months in Southeast Asia, the most influenced region. The results are considerable for developing strategy of adaptation especially for developing countries.</p>

Abstract An important aspect of the rehabilitation of burn patients is social participation, including daily activities and work. Detailed information on long-term activity impairment and employment is scarce. Therefore, we investigated activity impairment, work status, and work productivity loss in adults 5–7 years following burn injuries, and investigated associations with burn-specific health-related quality of life (HRQL) domains. Adult participants completed the Work Productivity and Activity Impairment General Health questionnaire and the Burn Specific Health Scale-brief (BSHS-B) 5–7 years post-burn. Outcomes were compared between participants with mild/intermediate and severe burns (>20% total body surface area burned). Seventy-six (36%) of the 213 participants experienced some degree of activity impairment due to burn-related problems 5–7 years post-burn. Seventy percent of the population was employed; 12% of them experienced work productivity loss due to burn-related problems. Nineteen percent reported changes in their work situation (partly) because of the burn injury. A higher proportion of participants with severe burns had activity impairments (56% vs 29%; P = .001) and work productivity loss (26% vs 8%; P < .001) compared to participants with mild/intermediate burns. Activity impairment and work productivity loss were both associated with burn-related work problems and lower mood, measured with the BSHS-B. In conclusion, a substantial part of the study population experienced activity impairment and work productivity loss, was unemployed, and/or reported changes in their work situation due to their injury. Particularly patients with severe burns reported productivity loss and had lower employment rates. This subscribes the importance of addressing work-related functioning in the rehabilitation of burn patients.

The Impact

The impact of globalization on multinational enterprises was examined from the years 1980 to 2020. A scoping literature review was conducted for a total of 141 articles. Qualitative, quantitative, and mixed typologies were categorized and conclusions were drawn regarding the influence and performance (i.e., positive or negative effects) of globalization. Developed countries show more saturated markets than developing countries that favor developing country multinational enterprises to rely heavily on foreign sales for revenue growth. Developed country multinationals are likely to use more advanced factors of production to create revenue, whereas developing country multinationals are more likely to use less advanced forms. A number of common trends and issues showed corporate social responsibility, emerging markets, political issues, and economic matters as key to global market production. Recommendations signal a strong need for more research that addresses contributive effects in the different economies, starting with the emerging to the developed. Limitations of data availability and inconsistency posed a challenge for this review, yet the use of operationalization, techniques, and analyses from the business literature enabled this study to be an excellent starting point for additional work in the field.

Background:Limited data exist of work productivity loss in patients with Rheumatoid Arthritis (RA), Psoreatic Arthritis (PsA) and Spondyloarthritis (axSpA).Objectives:The objective of this research was to assess productivity loss and absenteeism in patients with RA, PsA and axSpA.Methods:The study was designed as a cross-sectional study aimed to collect patient-reported outcomes from patients with RA, PsA and axSpA in Denmark via a nurse administered questionnaires and patient journals. Patients ≥18 years with RA, PsA or axSpA were consecutively recruited for the study over a 6-month period via routine visits to outpatient rheumatology clinics. Descriptive statistics were analyzed using SAS.Results:Of 488 respondents, 62% were women and mean age was 53.5 years (RA:57.4; PsA:52.6; axSpA:43.6). Average time since diagnosis was 11-15 years, however, for PsA and axSpA most patients answered 6-10 and 0-5 years, respectively. 280 (57%) answered that they had a job and completed the WPAI questionnaire (RA: 149 (51%); PsA: 48 (56%); axSpA: 83 (75%)). Average work hours was 31.9 in the last week (RA:31.2; PsA:33; axSpA:32.4). Average missed work hours were 4.3 in the last 7 days ((RA:4.0; PsA:4.2; axSpA:4.8), of which 32% was missed due to their inflammatory arthritis (RA:30%; PsA:38%; axSpA:32%). Mean absenteeism was highest for patients with PsA (mean=6.8; SD=17.7) followed by patients with axSpA (mean=5.4; SD=15.1) and with RA (mean=3.4; SD=12.2). Mean productivity loss was 20.5 (SD=23.8) for patients with RA, 27.6 (SD=25.8) for PsA and 26.3 (SD=25.8) for axSpAConclusion:We found that patients with PsA or axSpA miss more hours of work compared with patients with RA and when they are at work they have a higher absenteeism/lower productivity. This even though that both the group of patients with PsA and the axSpA were younger and had lived less time with their diagnosed disease compared with the group with RA.Disclosure of Interests:Trine Pilgaard Shareholder of: Pfizer, Employee of: Pfizer, Bente Appel Esbensen: None declared, Sandra Elkjær Stallknecht Consultant of: Pfizer

AbstractThe chronic eye disorder, neovascular age-related macular degeneration (nAMD), is a common cause of permanent vision impairment and blindness among the elderly in developed countries, including Japan. This study aimed to investigate the disease burden of nAMD patients under treatment, using data from the Japan National Health and Wellness surveys 2009–2014. Out of 147,272 respondents, 100 nAMD patients reported currently receiving treatment. Controls without nAMD were selected by 1:4 propensity score matching. Healthcare Resource Utilisation (HRU), Health-Related Quality of Life (HRQoL), and work productivity loss were compared between the groups. Regarding HRU, nAMD patients had significantly increased number of visits to any healthcare provider (HCP) (13.8 vs. 8.2), ophthalmologist (5.6 vs. 0.8), and other HCP (9.5 vs. 7.1) compared to controls after adjusting for confounding factors. Additionally, nAMD patients had reduced HRQoL and work productivity, i.e., reduced physical component summary (PCS) score (46.3 vs. 47.9), increased absenteeism (18.14% vs. 0.24%), presenteeism (23.89% vs. 12.44%), and total work productivity impairment (33.57% vs. 16.24%). The increased number of ophthalmologist visits were associated with decreased PCS score, increased presenteeism and total work productivity impairment. The current study highlighted substantial burden for nAMD patients, requiring further attention for future healthcare planning and treatment development.

Background:Spondyloarthritis is a group of chronic inflammatory diseases involving axial and peripheral joints. It mainly affects young patients typically of working age. Therefore, its impact on work outcomes may be considerable particularly in military patients.Objectives:The aim of this study was to evaluate the impact of spondyloarthritis on work ability and productivity in military patients, and to assess relationship between work productivity loss and disease activity.Methods:Thirty Three patients diagnosed with spondyloarthritis in the militay hospital of Tunis were included in the study. Age, gender and C-reactive protein were recorded. Data related to duration of the disease, Ankylosing Spondylitis Disease Activity Score (ASDAS) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) were also recorded. Employed patients completed Work Productivity and Activity Impairment (WPAI) questionnaire witch assesses four subscales: presenteism, absenteism, overall work impairemend and daily activity impairement in the 7 past days.Results:Among the thirty three patients, 63 % were men and 37% were women. The average age was 43,7 ± 13,5. The average duration of disease was 8,5 ± 7,75 years. Mean C-Reactive protein was 27,5 ± 39,3. Mean ASDAS and BASDAI were 3,12 ± 1,39 and 4,26 ± 1,78 respectively. 22 patients (66%) had an active disease and 11 (33%)were in remission. 48,4% of patients were using NSAIDs, 48,4% were under DMARDs and 42% were under biologics (12 patients using TNF-alpha blockers and 2 patients were given IL-17 inhibitors). Among this patients, 27 were employed. Three patients (11%) had a total work disability and were retired from work and two have been outplaced.Employed patients worked an average of 35,6 ± 10,3 hours per week and missed an average of 3,48 ± 6,49 hours per week. The mean rates of absenteeism, presenteeism and work productivity loss were 8,8 ± 16,9 %, 48,4 ± 19,9 % and 48,6 ± 19,7 %.There was a statistically significant correlation between BASDAI and work missed hours (p<0,05, r=0,48), absenteeism (p<0,05, r=0,48), presenteeism (p<0,01, r=0,669), work impairement (p<0,01, r=0,669), activity impairement (p<0,05, r=0,475) and work productivity loss (p<0,05, r=0,475), as well as between ASDAS CRP and presenteeism (p<0,05, r= 0,593), work impairement (p<0,05, r=0,593), activity impairement(p<0,05, r=0,460) and work productivity loss (p<0,05, r=0,460). No relation was found between WPAI indexes and C-reactive protein.Conclusion:This study demonstrates that spondyloarthritis has a major impact on military patients’ work productivity with a significant correlation between WAPI indexes and disease activity scores (ASDAS CRP and BASDAI). No relation was found with C-reactive protein.Disclosure of Interests:None declared.

Background:Poorer work productivity due to pain and functional impairment is commonly seen in ankylosing spondylitis (AS) patients, which may contribute to huge social economic burden. However, data about work outcomes and associated factors in Chinese AS patients were barely reported.Objectives:To assess work outcomes and identify factors associated with poor work productivity in patients with AS in China.Methods:A cross-sectional study was conducted in China. Adult patients (aged ≥ 18 years) fulfilled the 1984 New York modified criteria of AS were enrolled from rheumatology center from Jan 2017 to Aug 2017. All participants completed questionnaires about socio-demographic characteristics, disease characteristics, quality of life and the Work productivity and activity impairment questionnaire in AS (WPAI:SpA) to accesses the impact of chronic health conditions on job performance and productivity. Factors associated with work outcomes were evaluated.Results:A total of 91 patients with AS were included: 87.8% males, 78.02% employed, mean age and disease duration of 30 and 10 years respectively. The mean (SD) activity impairment of all patients was 48.57% (22.02%). For patients with employed work, mean (SD) absenteeism, presenteeism and work productivity loss were 10.22% (19.44%), 43.86% (22.48%) and 47.92% (25.81%) respectively. In multivariable analysis, activity impairment was associated with Bath Ankylosing Spondylitis Functional Index (BASFI) (P<0.01) and Ankylosing Spondylitis Quality of Life (ASQoL) (P<0.01). Absenteeism was associated with disease duration (P=0.03). Presenteeism was associated with disease duration (P=0.04), BASFI (P<0.01) and ASQoL (P<0.01). Work productivity loss was associated with BASFI (P<0.01) and ASQoL (P<0.01).Conclusion:Longer disease duration, reduced physical function and poorer quality of life are associated with reduced work productivity in Chinese AS patients.References:[1]Boonen A, van der Heijde D, Landewe R, Spoorenberg A, Schouten H, Rutten-van Molken M, et al.

Background:Work productivity of patients with spondyloarthritis is frequently affected by their disease.Objectives:We aim to identify disease-related factors associated with poor work productivity in patients with spondyloarthritis.Methods:A cross-sectional study was performed in patients with spondyloarthritis. Data on disease characteristics were collected as well as specific indices: Visual analogue scale (VAS) for fatigue and pain, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Ankylosing Spondylitis Disease Activity Score with CRP (ASDAS-CRP), Bath Ankylosing Spondylitis Functionnel Index (BASFI) and Bath Ankylosing Spondylitis Metrology Index (BASMI). EuroQol-5D (EQ5D) was used to assess health-related quality of life. Work productivity was assessed by the Work Productivity and Activity Impairment scale (WPAI:SpA). Factors associated with presenteeism, absenteeism and work productivity loss were evaluated.Results:One hundred patients were enrolled (73 men and 27 women); mean age was 43.68 ± 10.3 years. Fifty nine percent of patients were employed, 26% were off work and 15% were retired of which 8% were in early retirement. Sixty seven percent of patients had ankylosing spondylitis, 17% had rheumatism associated with inflammatory bowel disease and 16% had psoriatic rheumatism. The average disease duration was 12.24 ± 8.73 years. Mean age at onset was 33.2 ± 10 years [18-59]. The average diagnostic delay was 2.41 ± 3 years; it was more than five years in 17% of cases. Sacroiliac pain has been noted in 69 patients, lumbar or cervical stiffness in 78 patients and peripheral joint involvement in 18 cases. Thirty one percent of patients had hip joint involvement and 49% had extra-articular manifestation. Fifty percent had inflammatory biological syndrome, 63% were treated with anti-TNFα and 58% needed symptomatic treatment regularly. The mean fatigue and pain VAS was respectively 5.58 ± 2.5 and 5.56 ± 2.9. The mean BASDAI was 4.4 ± 2.4, the average BASFI was 4.6 ± 2.7 and the average ASDAS-CRP was 2.77 ± 1.18. The mean BASMI was 4.4 ± 2.8. The mean EQ5D score was 0.485 ± 0.378. Among employed patients, mean absenteeism, presenteeism and work productivity loss was 21.8 ± 33.13%, 42 ± 32% and 46.5 ± 35.31%, respectively. These work outcomes were correlated to diagnostic delay ≥ 2 years (p<0.03), peripheral joint involvement (p=0.006), psoriasis (p=0.02), inflammatory biological syndrome (p<0.001), need of symptomatic treatment (p=0.001), fatigue and pain VAS ≥ 4 (p<0.001), BASDAI ≥ 4 (p<0.001), ASDAS-CRP ≥ 2.1 (p<0.001), BASFI ≥ 4 (p<0.001), BASMI ≥ 4 (p=0.002) and low EQ5D score (p<0.001). Work productivity loss was in addition correlated to age at onset < 25 years (p=0.03).Conclusion:Active disease, reduced physical function and poorer quality of life are associated with reduced work productivity. Early diagnosis and good disease management especially fatigue and pain can potentially improve work outcomes in patients with spondyloarthritis.Disclosure of Interests:None declared.

Abstract Introduction Mobile phone use at night is associated with worse sleep quality. It may also be associated with daytime productivity, possibly via anxiety. Methods Data were obtained from the Sleep and Healthy Activity, Diet, Environment, and Socialization (SHADES) study, including N=1007 adults age 22–60. Mobile device use in bed was assessed as the frequency that participants reported: a device in the bedroom, use of the device in bed, texting, emails, internet browsing, calls, and/or social networking in bed, being woken up by the device in a planned (alarm) or unplanned (alert/call/message) way, and checking the phone at night. Each of these were coded as “never,” “rarely,” or “often.” Work productivity was assessed with the Well-Being Assessment of Productivity (WBA-P; scores 0–22 measure productivity loss). Regressions with WBA-P score as outcome and mobile phone variables as predictors were adjusted for age, sex, race/ethnicity, education, and income level. Post-hoc analyses included GAD7 score to examine the mediating role of anxiety. Results The presence of a device was not associated with productivity loss, but frequent use (“often”) was (B=1.26,p=0.01). Increased productivity loss was also seen in those who frequently (“often”) sent texts (B=1.20,p=0.008), browsed internet (B=1.14,p=0.01), emailed (B=2.09,p&lt;0.0005), called (B=1.42,p=0.004), and used social media (B=1.26,p=0.004). Productivity loss was associated with being woken by a call/alert “rarely” (B=1.20,p=0.001) or “often” (B=1.72,p=0.005), but not by alarm. Checking the phone at night “rarely” (B=0.89,p=0.01) and “often” (B=1.73,p&lt;0.0005) were also associated with productivity loss. When anxiety was entered into the model, all relationships except those with frequent emails and calls in bed became nonsignificant. Conclusion Anxiety may be the underlying cause for both increased mobile phone usage and reduced productivity. Reducing anxiety levels may indirectly aid in decreasing nighttime mobile phone use and increasing daytime productivity.

Objective.Indicators of work role functioning (being at work, and being productive while at work) are important outcomes for persons with arthritis. As the worker productivity working group at OMERACT (Outcome Measures in Rheumatology), we sought to provide an evidence base for consensus on standardized instruments to measure worker productivity [both absenteeism and at-work productivity (presenteeism) as well as critical contextual factors].Methods.Literature reviews and primary studies were done and reported to the OMERACT 12 (2014) meeting to build the OMERACT Filter 2.0 evidence for worker productivity outcome measurement instruments. Contextual factor domains that could have an effect on scores on worker productivity instruments were identified by nominal group techniques, and strength of influence was further assessed by literature review.Results.At OMERACT 9 (2008), we identified 6 candidate measures of absenteeism, which received 94% endorsement at the plenary vote. At OMERACT 11 (2012) we received over the required minimum vote of 70% for endorsement of 2 at-work productivity loss measures. During OMERACT 12 (2014), out of 4 measures of at-work productivity loss, 3 (1 global; 2 multiitem) received support as having passed the OMERACT Filter with over 70% of the plenary vote. In addition, 3 contextual factor domains received a 95% vote to explore their validity as core contextual factors: nature of work, work accommodation, and workplace support.Conclusion.Our current recommendations for at-work productivity loss measures are: WALS (Workplace Activity Limitations Scale), WLQ PDmod (Work Limitations Questionnaire with modified physical demands scale), WAI (Work Ability Index), WPS (Arthritis-specific Work Productivity Survey), and WPAI (Work Productivity and Activity Impairment Questionnaire). Our future research focus will shift to confirming core contextual factors to consider in the measurement of worker productivity.
