Determining the influence of video-based benchmarking (VBB) on examiner variability in objective structured clinical exams (OSCE)
Introduction Reducing examiner variability in Objective Structured Clinical Exams (OSCEs) is a priority within clinical performance assessment. In contrast to typical OSCE examiner training, video-based benchmarking (VBB) involves examiners scoring videos a/from their specific station b/shortly before the OSCE and then reflecting on and discussing scores/justifications agreed by an expert panel. Whilst realist evaluation has described mechanisms …
Simulated patient judgements of medical student performance in OSCEs
INTRODUCTION: Simulated patients (SPs) are widely used in Objective Structured Clinical Examinations (OSCEs) and increasingly contribute to summative scoring in high-stakes clinical assessments. While their judgments inform pass-fail decisions, concerns remain about variability and potential bias. There is limited theory-driven evidence explaining how SP involvement contributes to assessment decisions, and under what conditions this supports fair…
An investigation of space and space-time clustering in a large sample of infants with neural tube defects born in Cardiff
Altogether 406 infants with neural tube defects born in Cardiff between 1956-71 were investigated for evidence of space-time clustering and 100 similarly affected infants, together with matched controls born in Cardiff between 1964-66 were investigated for evidence of spatial clustering. No evidence of excessive prevalence in either dimension was observed
Neural tube defects in a country town
Eighteen infants with neural tube defects occurring in 979 births over five years in a small Wiltshire town were investigated for evidence of spatial epidemicity. Applying a method not used previously in the study of these defects, clustering was confirmed, a critical distance between cases of up to 100 metres giving a highly significant result (P = 0·001), and with one exception the observed number of pairs significantly exceeds the expected num…
Potato cultivation and storage in South Wales and its relation to neural tube malformation prevalence
The prevalence of neural tube malformations at birth is higher in the coalmining valleys of South Wales than anywhere else in England and Wales. In the eastern mining valleys of Glamorgan rates exceeded 1% of all births in the period 1964-66 (Richards, Roberts, and Lloyd, 1972). The preva lence in the coastal regions of South Wales is only half that in the mining valleys and this is not due to area differences in social class, parity, maternal ag…

Cyclic variations in date of last menstrual period of mothers of infants with congenital malformations in South Wales, 1964-66
In a review article on congenital malformations and season of birth, Bailar and Gurian (1965) stated that 'seasonal cycles in births of infants with certain malformations have been demonstrated beyond any reasonable doubt'. Recently, Wehrung and Hay (1970) have referred to the ambiguity of the term 'seasonal', and Hewitt et al. (1971) have pointed out that although a temporal pattern of behaviour may be demonstrated by an appropriate statistical …

An evaluation of developmental examination as a method of detecting neurological, visual, and auditory handicaps in infancy
discussed the value of universal neurological screening of the newborn in the light of criteria accepted as generally applicable to all screening procedures: firstly, that a reliable screening test should not give many false negative or positive results; secondly, that early detection is worth-while because early treatment has proved advant-ageous; and finally, that the use of medical and other resources is a reasonable priority in terms of total…
Manifestations of cerebral dysfunction in infancy and their association with toxaemia and antepartum haemorrhage. A cohort study
The delayed consequences of fetal and neonatal pathology are much more difficult to measure than their immediate influence on mortality. Those who die in late infancy or early childhood and, poten tially, those whose congenital handicap is an anato mical one visible at, or soon after, birth are count able. However, many other congenital disorders (for example, cerebral palsy and deafness) cannot be diagnosed in early infancy. The supposition that…
Developmental and neurological sequelae of the common complications of pregnancy and birth
IT is important to understand the influence of obstetric complications on the neurological develop-ment of the infant and young child since the future planning of preventive and social paediatric services will depend largely on the clarification of this issue. Since Little (1861) wrote about the influence of abnormal parturition, difficult labour, premature birth and asphyxia neonatorum on the mental and physical condition of the child, a continu…
Incidence of and relation between the common complications of pregnancy and delivery
Much has been written about the influence of the common complications of pregnancy and delivery on the development of the infant and young child. The discovery of correlations between some of these complications and certain developmental and neuro- logical abnormalities has led, among other things, to the establishment of an administrative procedure, the 'at risk' register, which aims at the early diagno- sis of handicaps by following up infants …
