Sara Marie Nilsen
About
I am part of the interdisciplinary research network Regforsk, where we use principles from randomised trials to analyse observational data. This is particularly relevant in health services research, as resource and ethical challenges often make randomised controlled trials impractical or impossible to conduct.
Over the past few years, I have participated in several projects on capacity pressure in health services, organisation of services, the effect of interventions, and patient safety.
I am also affiliated with the NTNU Life Course research group, where we aim to shed light on possible causal relationships between early life influences and later health and life chances.
My main position is at St. Olavs Hospital HF, where I also contribute with operational analyses.
Examples from research
Hospital delivery volume, travel time, and perinatal outcomes
We have investigated how hospital volume and travel time affect various outcomes, including perinatal mortality, risk of birth during transport, induction of labour, caesarean section, and instrumental delivery.
We used three analytical designs based on different assumptions to triangulate results and compared outcomes among women who:
- gave birth at hospitals of different sizes and with varying travel times, adjusted for observed confounding factors
- moved between catchment areas between births
- lived in neighbouring municipalities that were part of different catchment areas
Suicide and somatics
It is well known that individuals recently discharged from psychiatric care have a high risk of suicide. In this study, we also found an increased risk of suicide in the weeks after acute somatic hospital admissions, even after excluding admissions with known concurrent mental disorders, self-harm, or previous suicide attempts. This indicates a need for better follow-up regarding mental health care for these patients as well. The time-period right after discharge is particularly interesting because health services are often involved in various follow-up.
