The issue of anti-D: an integrated seamless approach from recognition of need to bedside administration.

BACKGROUND: The appropriate and timely administration of Anti-D immunoglobulin to Rhesus (D) negative women who have delivered Rhesus (D) positive babies is a vital part of obstetric care. Anti-D has an especially high profile in Ireland because of the tragic inadvertent transmission of Hepatitis C to Irish women in past decades. AUDIT: We have reviewed our policy and procedures pertaining to the administration of Anti-D for sensitising events during pregnancy and postnatally, in the Mid-Western Health Board in 1999/2000. As a result, major changes were made in the storage, issue, recording and administration of Anti-D. New procedures in the transfusion laboratory and in the maternity hospital have been accepted by scientists and midwives and supported by haematology and obstetric medical staff. The pharmacy and haematology laboratory no longer have a role in this programme. IMPLEMENTATION OF MULTI-DISCIPLINARY CHANGE MANAGEMENT: As a result of these changes, the storage, issuing and tracking of Anti-D has become the responsibility of the hospital blood bank. Measurement offoeto-maternal haemorrhage (FMH) is now the responsibility of bio medical scientists in blood bank, utilising both flow cytometry (increasingly recognised as the gold standard method) and the Kleihauer method (Kleihauer-Betke). The programme has moved from a doctor-administered IV Anti-D Ig, to a midwife-administered IM preparation. Prescription remains the responsibility of the doctor. These changes are facilitated by the protocol guided issue of the appropriate dose of Anti-D Ig by bio medical scientists to midwives. The issue of the Anti-D Ig occurs simultaneously with issue of results of mother and baby's serology testing and estimation of volume of FMH. These major changes have been guided by audit and needs assessment and require close liaison between medical, nursing and laboratory scientific staff in haematology, transfusion and obstetrics. CRITICAL INCIDENT AUDIT-CASE REPORT: Before new procedures became official policy, a critical incident audit allowed us to pilot our protocol and to revise it using draft new procedures. In this critical incident we describe successful management of a patient with a large foeto-maternal haemorrhage. This incident supported the need for the procedural enhancements already underway. This critical incident re-emphasised the need for the planned systems improvements to be introduced quickly.

The Dublin outcome for low birth-weight infants.

This report describes outcomes for all infants with birth weight 501-1750 grams born in the three major maternity hospitals in Dublin between 1.1.90 to 31.12.91. 37,958 mothers delivered 38,498 infants during this period, consisting of approximately 36% of all deliveries in Ireland. 633 (1.6%) of all infants born weighed 501-1750 grms. 102 (16%) were stillborn and 28 of the 531 live born infants had lethal malformations. 30% of women received two or more doses of antenatal steroids before delivery and a highly significant negative correlation occurred between the need for ventilation after birth and antenatal steroids. 56.4% of babies were delivered by caesarean section as compared with 10.8% of the hospital population. Of 503 liveborn infants without lethal malformation. 426 (85%) survived to 28 days and 419 (83%) to discharge home. 15% were growth retarded. 46% of infants were ventilated, mean duration of ventilation was 7 days. 25% of infants had an intraventricular haemorrhage, 10% necrotising enterocolitis and 19% culture proven sepsis. 15% of survivors developed broncho pulmonary dysplasia and 12% retinopathy of prematurity. This paper describes important information for mortality, morbidity and interventions among a large population of low birth weight infants in Ireland and can be used as a basis against which to compare future alterations in practice. It demonstrates a clear benefit for antenatal steroids in decreasing the need for ventilation and the importance of ensuring their utilisation antenatally where possible.
