2) It can help identify areas where more studies are needed (Finckh and Tramèr, 2008). (in this case, why US physicians are at higher risk than rest of the world, etc.)

Limitation: Due to larger sample size over different studies, there may be inconsistent in data collection process and language use. Different countries have different health care systems, which may lead to different stressors. This is a variable that was not taking into consideration.

1) cohort study/observational study

2) cohort was identified within the Mortality Disparities in American Communities (MDAC) data set linked to a National Death Index. 1,842 000 participants who were aged 26 years or older were selected

3) strength therefore of large sample, opportunity to immediately analysis data, and it is inexpensive, (Lam et al, 2020), large numbers of participants increase generalisability; data is gathered in real life conditions (Armstrong, 2012).

The investigator relinquished control over data collection methods by using an electronic data base and the sample is not randomised (Lam et al, 2020)

In essence it confirms higher suicide rates but suggests little is know about specific factors for a number of reasons though it suggests some at a very broad level which begs the question about the need for follow on research at some stage if this is a consistent view in the literature. i.e. if we cannot sufficiently isolate specific factors and there is no consensus what these are we must ask/investigate what are the specific set of healthcare worker risk factors. How are they different from the rest of the non healthcare workforce? Then what can be done about it. We could also test (in the future) the theory of whether there are specific factors or does the job exacerbate generic factors. The RQ is generating many other RQs in my head.
