Transfer of knowledge to diagnose infant abuse and its incidence - a time-series analysis from Sweden.

ABSTRACT:

Aim

To analyse the transfer of knowledge on how to detect physical abuse, especially shaken baby syndrome/abusive head trauma (SBS/AHT), and its association to trends in infant abuse diagnoses (maltreatment and assault).

Methods

Design: retrospective population-based and quasi-experimental.

Setting

Sweden 1987-2019.

Patients

Children below age 1 year, selected from the National Patient Register (n = 1150). Exposures: Literature search for transfer of knowledge by diffusion, dissemination and implementation, and whether supportive or disruptive of the SBS/AHT paradigm.

Main outcome measure

Abuse diagnoses (maltreatment or assault).

Analyses

Incidence rate, incidence rate ratio (IRR).

Results

The overall incidence rate of abuse was 32.23 per 100,000 during the years 1987-2019. It was rather stable 1987-2000. The SBS diagnosis was introduced in the late 1990s. A comprehensive increase of transfer of knowledge on physical abuse, specifically on SBS/AHT and dangers of shaking, took place from 2002 and onward through diffusion, dissemination and implementation. Maltreatment diagnoses, but not assault diagnosis, increased steeply during 2002-2007, peaking in 2008-2013 [IRR 1.63 (95% confidence interval 1.34-1.98)]. Transfer of disruptive knowledge on SBS/AHT during the period 2014-2019 was associated with a decline in maltreatment diagnoses [IRR 0.84 (95% confidence interval 0.71-0.99)].

Conclusion

An increase in maltreatment diagnoses was associated with transfer of supportive knowledge of the SBS/AHT paradigm, while a decline occurred toward the end of the study period, which might indicate a burgeoning de-implementation process.
