New study links generational tensions to lower workplace productivity

Published

on

Employees who are much younger than their managers report lower productivity than those closer in age due to a lack of collaboration between employees of different generations.

This is according to new research from the London School of Economics and Political Science (LSE) in collaboration with global consulting firm, Protiviti.

An external survey conducted by LSE of 1,450 employees in the finance, technology and professional services industries in the UK and USA, found that friction between different generations was driving down productivity and that firms need to develop intergenerationally inclusive work practices.

These include making it easier for each generation to ‘fit in’, developing and advancing people based on merit rather than age, and committing to a generationally diverse workforce.

Key findings were:

  • 25 per cent of employees surveyed self-reported low productivity.
  • Across generations, low levels of productivity are reported by 37 per cent of Gen Z, 30 per cent of Millennials, 22 per cent of Gen X, and 14 per cent of Baby Boomers.
  • Employees with larger age gaps with their managers report lower productivity. Those with managers more than 12 years their senior are nearly 1.5 times as likely to report low productivity.
  • Generations agree on the skills that are most important to productivity and career advancement. The top three skills being: active listening, time-management and judgement and decision making.

An ageing global population means there is less ‘younger talent’ in the pipeline in addition to increased generational diversity, with large firms regularly having five generations working together.

In firms that use intergenerationally inclusive work practices, productivity was higher in younger generations, researchers found. These practices include enabling colleagues of every generation to have similar levels of voice when collaborating and advancing employees based on merit regardless of their age.

The proportion of Gen Z employees reporting low productivity drops from 37 per cent to 18 per cent, and from 30 per cent to 13 per cent for Millennials. Across the board, 87 per cent of employees reported high productivity levels in firms with intergenerationally-inclusive work practices, compared to just 58 per cent of employees from firms without these practices. In addition, employees working at intergenerationally inclusive workplaces are twice as likely to be satisfied with their jobs and are less likely to look for a new role.

These findings are especially salient as the OECD predicts that the UK, US and the broader global economy will experience slow growth in 2024, putting pressure on companies to boost productivity.

Co-author, Dr Grace Lordan, founder and director of The Inclusion Initiative at LSE, who led the research, said: “I am not surprised that we discovered a ‘productivity manager age gap’. There is good evidence that across generations individuals have different tastes and preferences. So, why do we expect them to work easily together? We now have five generations working together in the workplace and the skills that are required to manage these dynamics are not usually being taught by firms. Our research shows that if we invest in giving these skills to managers, and creating an intergenerationally inclusive workplaces there are significant productivity gains to be had.”

The report, GENERATIONS, Unlocking the Productivity Potential of a Multigenerational Workforce marks the first of a multi-year research collaboration between The Inclusion Initiative at the LSE and Protiviti to explore how firms can capture the productivity potential that is available from getting colleagues of different generations working better together.

Matt Duncan, managing director, Protiviti Global Business Consulting, said: “Protiviti is delighted to collaborate with The Inclusion Initiative in becoming the inaugural founder of the Generations Hub. GENERATIONS is an important study focusing on an under-researched area of diversity in the workplace. Through this research, we hope to support our clients in creating productive and successful teams, taking proactive steps to improve organisational effectiveness and drive long-term success across the organisation.”

Air pollution linked to increased hospital admission for heart and lung diseases

Published

on

Exposure to fine particulate matter (PM2.5) air pollution is linked to an increased risk of hospital admission for major heart and lung diseases, find two large US studies, published by The BMJ.

Together, the results suggest that no safe threshold exists for heart and lung health.

According to the Global Burden of Disease study, exposure to PM2.5 accounts for an estimated 7.6% of total global mortality and 4.2% of global disability adjusted life years (a measure of years lived in good health).

In light of this extensive evidence, the World Health Organization (WHO) updated the air quality guidelines in 2021, recommending that an annual average PM2.5 levels should not exceed 5 μg/m3 and 24 hour average PM2.5 levels should not exceed 15 μg/m3 on more than 3-4 days each year.

In the first study, researchers linked average daily PM2.5 levels to residential zip codes for nearly 60 million US adults (84 per cent white, 55 per cent women) aged 65 and over from 2000 to 2016. They then used Medicare insurance data to track hospital admissions over an average of eight years.

After accounting for a range of economic, health and social factors, average PM2.5 exposure over three years was associated with increased risks of first hospital admissions for seven major types of cardiovascular disease – ischemic heart disease, cerebrovascular disease, heart failure, cardiomyopathy, arrhythmia, valvular heart disease, and thoracic and abdominal aortic aneurysms.

Compared with exposures of 5 μg/m3 or less (the WHO air quality guideline for annual PM2.5), exposures between 9 and 10 μg/m3, which encompassed the US national average of 9.7 μg/m3 during the study period, were associated with a 29% increased risk of hospital admission for cardiovascular disease.

On an absolute scale, the risk of hospital admission for cardiovascular disease increased from 2.59% with exposures of 5 μg/m3 or less to 3.35% at exposures between 9 and 10 μg/m3.

“This means that if we were able to manage to reduce annual PM2.5 below 5 µg/m3, we could avoid 23% in hospital admissions for cardiovascular disease,” say the researchers.*

These cardiovascular effects persisted for at least three years after exposure to PM2.5, and susceptibility varied by age, education, access to healthcare services, and area deprivation level.

The researchers say their findings suggest that no safe threshold exists for the chronic effect of PM2.5 on overall cardiovascular health, and that substantial benefits could be attained through adherence to the WHO air quality guideline.

“On February 7, 2024, the US Environmental Protection Agency (EPA) updated the national air quality standard for annual PM2.5 level, setting a stricter limit at no more than 9 µg/m3. This is the first update since 2012. However, it is still considerably higher than the 5 µg/m3 set by WHO. Obviously, the newly published national standard was not sufficient for the protection of public health,” they add.*

In the second study, researchers used county-level daily PM2.5 concentrations and medical claims data to track hospital admissions and emergency department visits for natural causes, cardiovascular disease, and respiratory disease for 50 million US adults aged 18 and over from 2010 to 2016.

During the study period, more than 10 million hospital admissions and 24 million emergency department visits were recorded.

They found that short term exposure to PM2.5, even at concentrations below the new WHO air quality guideline limit, was statistically significantly associated with higher rates of hospital admissions for natural causes, cardiovascular disease and respiratory disease, as well as emergency department visits for respiratory disease.

For example, on days when daily PM2.5 levels were below the new WHO air quality guideline limit of 15 μg/m3, an increase of 10 μg/m3 in PM2.5 was associated with 1.87 extra hospital admissions per million adults aged 18 and over per day.

The researchers say their findings constitute an important contribution to the debate about the revision of air quality limits, guidelines, and standards.

Both research teams acknowledge several limitations such as possible misclassification of exposure and point out that other unmeasured factors may have affected their results. What’s more, the findings may not apply to individuals without medical insurance, children and adolescents, and those living outside the US.

However, taken together, these new results provide valuable reference for future national air pollution standards.

Home health care linked to increased hospice use at end-of-life – study

Published

on

Patients who had previously received home health care had a higher likelihood of accessing hospice care at the end of their life, according to a new study.

Researchers, whose findings are published in the Journal of Palliative Medicine, examined the home health care and hospice care experiences of more than two million people.

Using Medicare data, researchers found when individuals received home health care before the last year of their life, they had higher odds of using hospice care than those who had never received home health care.

Researchers said this association underscores the potential benefits of receiving end-of-life care in the comfort of one’s home.

As the aged population increases, the findings also show the need for more resources in the health care sector and staff training in end-of-life care.

Home health care services including skilled nursing, therapy, social work and aide services are used to maintain functioning or slow decline in health. Hospice care provides similar services but is intended for those with life expectancies of six months or less and is focused on pain relief, minimising hospital visits and providing comfort and support. Both services provide patients the opportunity to receive more personalised care in their home.

Researchers say home-based care also encourages greater involvement of family caregivers in the caregiving process.

Olga Jarrín, senior author of the study, the Hunterdon Professor of Nursing Research at the Rutgers School of Nursing and director of the Community Health and Aging Outcomes Laboratory within the Rutgers Institute for Health, Health Care Policy and Aging Research, commented: “In addition to benefits for the patient, hospice care also provides resources and support to help family caregivers cope with the physical, emotional and practical challenges of caring for a loved one at the end of life.”

Hyosin (Dawn) Kim, research assistant professor at Oregon State University and first author of the study, added: “By providing personalised care, reducing hospitalisations, fostering family involvement and support, and improving symptom management, home-based care can enhance the quality of end-of-life experiences for patients with terminal illnesses and their families.”

Sleep programme shows promise in those with memory problems – study

Published

on

A new study has shown promising results in improving sleep and quality of life in individuals living with memory problems.

A group of researchers from Penn Nursing, Penn Medicine, Rutgers School of Nursing, and Drexel University’s College of Nursing and Health Professions, have delved into the efficacy of a non-pharmacological approach in a trial known as the Healthy Patterns Sleep Program.

The study involved 209 pairings of community-residing individuals with memory problems and their care partners. Participants were assigned to either the Healthy Patterns Sleep Program, which consisted of one-hour home activity sessions administered over four weeks, or a control group that received sleep hygiene training, plus education on home safety and health promotion.

The Healthy Patterns Sleep Program trained care partners in timed daily activities such as reminiscence in the morning, exercise in the afternoon and sensory activities in the evening that can decrease daytime sleepiness and improve nighttime sleep quality.

Nancy Hodgson, PhD, RN, FAAN, the Claire M. Fagin Leadership Professor in Nursing and Chair of Department of Biobehavioral Health Sciences, who led the study, said: “The results from this study provide fundamental new knowledge regarding the effects of timing activity participation and can lead to structured, replicable treatment protocols to address sleep disturbances. Overall, the Healthy Patterns program resulted in improved QOL compared to an attention-control group.”

The findings also indicate that, compared to a control group, the four-week Healthy Patterns program improved sleep quality among persons living with memory issues who had depressive symptoms or poor sleep quality.  The study indicates the Healthy Patterns Intervention might need a longer dose to induce improvements in other sleep-wake activity metrics.

The study’s significance lies in its confirmation of the effectiveness of behavioural interventions in not only improving quality of life and addressing sleep quality issues in this population, but also potentially reducing care partner burden and overall care costs for persons living at home with memory problems.
