This study, conducted in a Finnish city, examined whether decreasing emergency department (ED) services in an overcrowded primary care ED and corresponding direction to office-hour primary care would guide patients to office-hour visits to general practitioners (GP). This was an observational retrospective study based on a before-and-after design carried out by gradually decreasing ED services in primary care. The interventions were ( a) application of ABCDE-triage combined with public guidance on the proper use of EDs, ( b) cessation of a minor supplementary ED, and finally ( c) application of “reverse triage” with enhanced direction of the public to office-hour services from the remaining ED. The numbers of visits to office-hour primary care GPs in a month were recorded before applying the interventions fully (preintervention period) and in the postintervention period. The putative effect of the interventions on the development rate of mortality in different age groups was also studied as a measure of safety. The total number of monthly visits to office-hour GPs decreased slowly over the whole study period without difference in this rate between pre- and postintervention periods. The numbers of office-hour GP visits per 1000 inhabitants decreased similarly. The rate of monthly visits to office-hour GP/per GP did not change in the preintervention period but decreased in the postintervention period. There was no increase in the mortality in any of the studied age groups (0-19, 20-64, 65+ years) after application of the ED interventions. There is no guarantee that decreasing activity in a primary care ED and consecutive enhanced redirecting of patients to the office-hour primary care systems would shift patients to office-hour GPs. On the other hand, this decrease in the ED activity does not seem to increase mortality either.

To determine the extent to which it is possible to provide continuity of primary care for those who visit Emergency Departments (EDs) we studied how recorded diagnoses in primary care differ, depending on whether the patient is met in an ED or a primary care office-hours practice. In the present, 12-year follow-up study a report generator of the Electronic Health Record-system provided monthly figures for the number of different recorded diagnoses using the International Classification of Diagnoses (10 th edition, ICD-10) and the total number of ED doctors and office-hour visits to General Practitioners (GPs). The 20 most common diagnoses covered 48.1% of the visits with recorded diagnoses to the office hour GPs and 45.9% of the visits to the doctors of the ED. Of these 20 diagnoses, 10 were common in both systems. These 10 diagnoses constituted about 30% of the diagnoses given by ED doctors. Furthermore, five out of the six most common diagnoses were the same in the ED and office-hours practices. The doctors in EDs and office-hour GPs treat quite similar patient material. This may provide organisational ways to reorganise the work of primary care and to guarantee continuity of care for those who may benefit from it.

ABBREVIATIONS OCTOptical coherence tomography RNFL Retinal nerve fiber layer TSC Tuberous sclerosis complex VAVFD Vigabatrin-attributed visual field defect AIM To investigate the prevalence of vigabatrin-attributed visual field defect (VAVFD) in infantile spasms and the utility of optical coherence tomography (OCT) in detecting vigabatrin-related damage. METHOD We examined visual fields by Goldmann or Octopus perimetry and the thickness of peripapillary retinal nerve fiber layer (RNFL) with spectral-domain OCT at school age or adolescence. RESULTS Out of 88 patients (38 females, mean age at study 15y, SD 4y 3mo, range 6y 4mo-23y 3mo [n=65] or deceased [n=21] or moved abroad [n=2]) exposed to vigabatrin in infancy, 28 were able to perform formal visual field testing. Two had visual field defect from structural causes. We found mild VAVFD in four patients and severe VAVFD in one patient. Median vigabatrin treatment duration for those with normal visual field was 11 months compared to 19 months for those with VAVFD (p=0.04). OCT showed concomitant attenuated RNFL in three children with VAVFD, and was normal in one. The temporal half of the peripapillary RNFL was significantly thinner in the VAVFD group compared to the normal visual field group. INTERPRETATION The overall prevalence of VAVFD is lower after exposure in infancy compared to 52% which has been reported after exposure in adulthood. The risk increases with longer treatment duration. Further studies should identify infants particularly susceptible to VAVFD and clarify the role of OCT.
