Dr Sarah Hewko – Investigating Health Professionals’ Retirement Decision-Making

Feb 24, 2021 | Life Sciences & Biology, Medical & Health Sciences

The availability of skilled health practitioners is fundamental to the health of a nation. Unfortunately, many countries experience shortages of healthcare professionals. Shortages typically result when too few choose to enter the health professions and when too many exit the health professions, whether to pursue an alternate career or to retire. Dr Sarah Hewko, based at the University of Prince Edward Island, is conducting valuable research into the reasons why health professionals retire earlier than planned.

Ageing Populations and Healthcare

Even before the COVID-19 pandemic, health systems around the world were struggling to cope with increasing demands for medical care. In keeping with a trend that first presented in developed countries, nearly all countries are now having to meet the needs of an increasingly ageing population. This has significant implications for healthcare, as older adults tend to access health services more frequently. Furthermore, declining birth rates have led to there being fewer new entrants into the labour market. In a nutshell, more people are needing healthcare but there are fewer skilled professionals available to provide it.

The availability of skilled health practitioners is affected both by the number of individuals who enter the health professions (which depends, at least in part, on the availability of places in profession-specific training programs) and by the number of individuals who leave those professions, whether to retire or to pursue alternate employment.

Healthcare Professional Shortages Across the World

The Global Health Workforce Alliance and the World Health Organization recently reported a global deficit of skilled healthcare professionals of around 7.2 million – and this number is increasing. The consequences of such shortages vary but include increased costs of healthcare, increased wait times for health services, and longer working hours for existing staff.

Shortages in healthcare are present across professions, including in medicine, nursing, and the allied health professions. Allied health professionals (AHPs) include, among others, dietitians, pharmacists, physiotherapists and speech and language therapists. Unfortunately, the causes of workforce shortages within the allied health professions are under-researched. In particular, little is known about the factors influencing retirement in these professional groups.

Researching Retirement

Dr Sarah Hewko, Assistant Professor at the University of Prince Edward Island, has been researching how healthcare professionals approach retirement decision-making retirement for several years. In a key study, Dr Hewko utilised baseline data from the Canadian Longitudinal Study on Aging (CLSA). The CLSA is a national study which will follow approximately 50,000 Canadians, aged between 45 and 85 at the time of recruitment for 20 years. The CLSA is one of many databases across the globe tracking population-level outcomes of ageing.

Although the average age of retirement in Canada is 64, Dr Hewko found that AHPs were retiring, on average, between 56 and 60 years old (depending on profession) with RNs retiring at 58 years old. With early retirement defined as retirement below 65 years of age, Dr Hewko found that not only were many AHPs and RNs retiring ‘early’ but, in some cases, they were retiring earlier than they had planned. Her next step was to identify the reason(s) why.

Dr Hewko and her colleagues began by reviewing the available published research. From this, they developed a conceptual model of the factors most often reported to affect early retirement decision making in RNs and AHPs. A conceptual model is essentially a visual representation of key factors (or variables) proposed to influence an outcome – in this case, early retirement.

Figure 1: Conceptual model of early retirement among registered nurses and allied health professionals.

Conceptualising Early Retirement

In Dr Hewko and her colleagues’ conceptual model, factors proposed to affect early retirement were identified based on previously published findings. These fell into eight broad categories (as shown in Figure 1).

Workplace characteristics included whether older workers were recognised and valued in the workplace, the frequency of structural and/or technological change, and the flexibility of working hours. Age-related stigma and discrimination can be characteristic of a workplace and may cause health professionals to retire early if, as they age, they come to view the workplace as an increasingly unwelcome space. Other work-related factors included work schedule (e.g., days/nights, rotating shifts), how long the individual had been working over their entire career, and how long they had been working for the current organisation.

Sociodemographic factors, such as educational level, financial security and childcare responsibilities also featured in the model. For example, healthcare professionals who perceive themselves as financially secure may decide to retire early as they can afford to support themselves without working. The related category of family incorporated factors such as whether one’s partner was retired, the partner’s health status, and caregiving responsibilities, such as caring for elderly parents.

Lifestyle and health-related factors are also critical to decisions surrounding retirement in later life. Through the process of ageing, our health may begin to deteriorate to the point where working is no longer practical. As such, physical and psychological health status, level of physical activity and the presence of any disability will affect an individual’s ability to work and be a significant contributing factor to the decision to retire. Societal expectations may also lead individuals to retire early (or earlier than planned) as others begin to perceive them as ‘infirm’ or less physically capable (even if their performance remains unchanged).

A healthcare professional’s attitudes and beliefs around work and retirement also influence retirement decisions. Job satisfaction is a key element of this, as is the individual’s level of commitment to the organisation and/or their occupation. Personal views of retirement are also important, alongside an individual’s desire to have more time for leisure activities.

Across all occupations, the broader context of age, within the context of ‘generations’, is a much-discussed factor that may influence the timing of retirement. The generation known as ‘baby boomers’ (born between 1946 and 1964) reached 65 years beginning in 2011 and the subsequent ‘generation x’ is the next to face retirement.

Another factor was the ‘location of residence’, which is associated with differences in legislation, taxation and labour laws across municipalities, provinces, states and districts. Characteristics and policies of the employing organisation also affect the decision to retire. Incentives to leave for early retirement may be featured during planned organisational restructuring, increasing the appeal of early retirement for the individual.

We can see that many factors proposed in the model interact with others, both within each category and across categories. For instance, the flexibility of working hours (which falls under ‘workplace characteristics’) may affect whether or not a healthcare professional decides to continue working alongside caring for older family members (a factor considered under the category of ‘family’).

The conceptual model of early retirement was validated for clarity, logic and comprehensiveness by Dr Hewko through a series of interviews with Canadian RNs and AHPs. Interviewees confirmed that the model was clear, logical and included all the factors relevant to early retirement among health professionals.

Application of the Conceptual Model to Data

Following the validation of the model, Dr Hewko tested its ability to account for early retirement in RNs and AHPs, drawing again on data from the CLSA. Using a pared down version of the model (see Figure 2), the categories of ‘attitudes and beliefs’, ‘organisational factors’, ‘sociodemographics’, ‘age’ (broader context) and ‘family’ were able, to some extent, to (statistically) explain the real-world data for both RNs and AHPs. This demonstrated the utility of the model.

Of the specific factors of interest, Dr Hewko identified that both RNs and AHPs reported organisational restructuring as influencing their decision to retire early. For RNs, further significant factors including early retirement being financially viable, profession of a desire to stop working, and caregiving responsibilities.

Proposed Avenues of Change

Given the urgent shortage of healthcare workers and the healthcare requirements of the increasingly ageing population, there is a clear need to retain healthcare workers in the workforce for as long as possible. Extending the work-lives of RNs and AHPs by an average of even 6 months each could have a significant impact on national workforce shortages and the sustainability of health systems.

Organisational restructuring often occurs in response to budget restrictions and can involve the elimination of certain roles, as well as changes to reporting structures. Older workers may be more affected by restructuring as they tend to be on higher salary bands and therefore cost organisations more. Older workers, particularly those who have been with the employer for a long time, are significant sources of organisation-specific historical knowledge and are of significant value in the efficient and effective training of newly hired professional staff and student health professionals. As one of the few work-specific factors identified as influential to retirement decision-making by both RNs and AHPs, it is, fortunately, one of the easiest to address.

Dr Hewko recommends effective and frequent communication throughout organisational restructuring as a method to lessen uncertainty that might contribute to healthcare professionals opting for early retirement. She also recommends stronger collaborations between trade unions and hospital management to avoid adverse impacts resulting from restructuring.

Critically, for RNs, caregiving responsibilities were associated with 7.2 times greater likelihood of early retirement. This is perhaps unsurprising given that women are, in addition to their vocation, likely to also fill the stereotypically nurturing roles of mother, wife and daughter. Noting this, Dr Hewko argues for greater implementation of caregiver-friendly policies to encourage healthcare professionals to remain in the workforce while caregiving and to facilitate penalty-free short-term exits from employment to fulfil time-limited needs for full-time caregiving, such as during cancer treatment regimes, post-surgery or at the end-of-life.  

Dr Hewko’s work has highlighted the interrelated and often complex factors that contribute to a healthcare professional’s decision to retire at a certain point in their lives. With support from the Ireland Canada University Foundation, she will be travelling to Ireland in the coming year to conduct analyses looking at similarities and differences in retirement decision making among registered nurses (RNs) and AHPs in Ireland and Canada.

As such, Dr Hewko’s further research will continue to provide knowledge that will be key to building and maintaining sustainable healthcare systems. Through understanding the reasons why people retire early, efforts can more effectively be focused on retaining more healthcare professionals for a longer period of time and addressing health workforce shortages in Canada and beyond.

Professor Michael Ryan | What the Ugandan Response to HIV/AIDS Can Teach Us About Collaborative Governance

Persistent problems such as poverty, disease and hunger are of critical interest to organisation and management scholars. Developing countries often struggle with intractable social issues, including susceptibility to epidemics. The complexity of these challenges means it can be difficult for leaders to organise governance and ensure that resources and capabilities are effectively coordinated. Professor Michael Ryan looks at the case study of the HIV/AIDS response in Uganda, and asks how this can contribute to our understanding of public organisation and state capacity. In particular, he explores how Uganda was successful in using collaborative governance to manage the HIV/AIDS crisis.

Adipose tissue is more commonly known as body fat. Unlike white adipose tissue, which is linked to negative cardiovascular outcomes such as metabolic syndrome, brown adipose tissue is positively related to health and may reduce the risk of cardiometabolic diseases. Professor Aaron Brown and his team at the MaineHealth Institute for Research are working to understand brown adipose tissue regulation and explore its therapeutic potential. They have already made significant advancements through the application of optogenetics, a cutting-edge technique that harnesses the power of light to precisely manipulate specific cellular processes.

Who gets to be a theorist? What kinds of theoretical work get marginalised in academic research? And how does this oppression play out in the peer-review process? Dr Kimberly Kay Hoang is a Professor of Sociology at the University of Chicago. She has explored how difficult it is to get your sociology research published if you are not using research deemed to be legitimate by reviewers. She brings awareness to these issues and argues for change amongst scholars so that new forms of knowledge are not missed, especially regarding feminist, minority and racial theories.
