Pathways to specialist community perinatal mental health services: a two-site longitudinal retrospective service evaluation.

BACKGROUND

During pregnancy and the postpartum period, women's mental health can deteriorate quickly. Timely and easy access to services is critically important; however, little is known about the pathways women take to access services. Previous research has shown that women from ethnic minority groups in the United Kingdom experience more access issues compared to the White British women.

AIM

To describe pathways taken to specialist community perinatal mental health services and explore how they vary across services and ethnic groups.

METHODS

This is a two-site, longitudinal retrospective service evaluation conducted in Birmingham and London during 6 months (1 July-31 December 2019). Electronic records of 228 women were accessed and data were extracted on help-seeking behaviour, referral process and the type of pathway (i.e. simple or complex). Data were collected using the adapted World Health Organization encounter form and analysed using uni- and multivariable analyses.

RESULTS

The median time from the start of perinatal mental illness to contact with perinatal mental health services was 20 weeks. The majority of patients accessed perinatal mental health services through primary care (69%) and their pathway was simple, that is they saw one service before perinatal mental health services (63%). The simple pathway was used as a proxy for accessible services. In Birmingham, compared to London, more referrals came from secondary care, more women were experiencing current deterioration in mental health, and more women followed a complex pathway. Despite differences between ethnic groups regarding type of pathway and duration of patient journey, there was no evidence of difference when models controlled for confounders such as clinical presentation, general characteristics and location. The service's location was the strongest predictor of the type of pathway and duration of patient journey.

LIMITATIONS

The heterogeneity among categorised ethnic groups; data extracted from available electronic records and not validated with patient's own accounts of their pathways to care; unanalysed declined referrals; the study was conducted before the COVID-19 pandemic and pathways may be different in the post-COVID-19 period.

CONCLUSION

The study provides important insights into how patients find their way to community perinatal mental health services. It shows that there is a great degree of variability in the time taken to get into these services, and the pathway taken. This variation does not come from different needs of patients or different clinical presentations but rather from service-level factors.

FUTURE WORK

The studied community perinatal mental health services in the United Kingdom operate with a significant degree of variability in the types and characteristics of patient pathways. Future research should explore these issues on the national and international levels. Additionally, future research should explore the reasons for the different pathways taken and the outcomes and risks associated with them.
