An introduction to epidemiology. Please ask any questions you have about starting a career in epidemiology. Enjoy!
Sometimes it feels like my entire life has been spent behind a computer. From studying to writing essays to working on my research, I spend a lot of time on my own staring at a blinking cursor. As much as this is a reality of my studies in biostatistics and epidemiology, I cannot help but feel I am missing an integral part of the health sciences academic experience. That is collecting data and interacting with the subjects of my research. I rarely encounter people who are not either fellow academics or students. I am beginning to wonder what it is like in that big, bright world outside the ivory tower?
I recently had the opportunity to glimpse at this world when I shadowed a fellow graduate student and former clinical lead with the Portland Hotel Society in the Downtown Eastside (DTES) of Vancouver. His work involved a project on which my supervisor and research lab had done the statistical analysis. It was a unique opportunity for me to see the neighbourhood and people behind the de-identified statistical IDs I use for modeling. His responsibilities included running an arm of the study that provided housing interventions, including both managerial and counseling work, for homeless residents of the DTES.
He worked with these people on a one-to-one basis, planning treatment regimes for both mental and health services using a strong, team-based approach. This, ultimately, could not be more different than what I do. The world of collecting data, which is a rather cold way of saying providing services and working with participants, is the entire basis of my work. I could not run a statistical analysis without that data, yet I rarely get the chance to understand the circumstances of how it is collected. More importantly, I have few opportunities to understand the people the data represents. I keenly felt this reality during my shadowing time.

As I discovered, working with the participants could be a nine-to-five job but with the added caveat of extended hours for emergencies. The stark reality is that you need to be available when people die, often not within normal working hours. I have no concept of this type of stress. When I asked what that felt like, I received the expected response, not at all pleasant. There are however mental health strategies in place for this type of work including flexible hours, staff activities and vacation time. I realize, as typing this, that these emergencies faced by clinical staff are the very same numbers I see in a statistical database as censoring dates, or time of leaving the cohort. That is something I will take away from the experience with a slightly heavy heart. As I walked around the DTES during my shadowing, several people stopped us whether to catch up, chat or request help. It was amazing, the connections I saw, this work is definitely not done while staring at a blinking cursor.
As I reflect on this experience my most central question is how important is it that I know these “real-world” realities? Does it matter for statistical modeling? I hope that the answer is yes. It brings me back to the idea of multidisciplinarity. We need to understand more than our own training to develop effective multidisciplinary teams (Choi & Pak, 2006). I try to represent real-world health phenomena with biostatistical models. I must know the context of the problem in order to create reliable analyses. As well, understanding the inequities of our world is important to me personally. I work in this field because I care about health at the population level, particularly for those most vulnerable to poor health. I am sure as I progress in my career I will have more opportunities to work outside of a computer lab. To extend my initial metaphor, I wonder in the meantime what champion will release me from this locked tower? Luckily no actual chains exist and that champion, I imagine, will be my own ardent effort to fight against the idea that I am only a “numbers person”. Escape from the tower requires that I simply push through the door.
