Iatrogenic disorders in modern neonatology: a focus on safety and quality of care

Iatrogenic Skin Disorders and Related Factors in Newborn Infants

BACKGROUND/OBJECTIVES

Recent technological advances and diagnostic and therapeutic innovations have resulted in an impressive improvement in the survival of newborn infants requiring intensive care. Consequently, with the use of modern invasive diagnostic and therapeutic procedures, the incidence of iatrogenic events has also increased. The aim of this study was to assess various iatrogenic complications in neonates requiring intensive care and determine possible contributing factors to the injuries.

METHODS

Our prospective cross-sectional cohort survey was conducted in a central regional level III neonatal intensive care unit (NICU). Correlations between intensive therapeutic interventions, complications, factors influencing attendance and prognosis, and the prevalence of iatrogenic skin injuries (ISIs) were investigated over a 2-year study period.

RESULTS

Between January 31, 2012, and January 31, 2014, 460 neonates were admitted to the NICU, 83 of whom exhibited some kind of ISI. The major risk factors for ISIs were low birthweight, young gestational age, long NICU stay, use of the intubation-surfactant-extubation (INSURE) technique, surfactant use, mechanical ventilation, insertion of an umbilical arterial catheter, circulatory and cardiac support with dopamine or dobutamine, pulmonary hemorrhage, intracranial hemorrhage, patent ductus arteriosus, bronchopulmonary dysplasia, and positive microbiology culture results.

CONCLUSION

To prevent ISIs, careful consideration of risk factors and the creation of protocols ensuring efficient treatment of injuries are needed.

The heterologous (non-specific) effects of vaccines: implications for policy in high-mortality countries

There are important interactions between vaccines, and between vaccines and unrelated (heterologous) infections. In high-mortality regions, until the next vaccine is given, live vaccines such as bacillus Calmette-Guérin (BCG) and measles vaccines reduce mortality from infections such as pneumonia and sepsis. However, non-live vaccines such as diphtheria, tetanus and whole-cell pertussis vaccine (DTP) may increase mortality from infections other than diphtheria, tetanus and pertussis. All-cause mortality might be reduced if an extra dose of Edmonston-Zagreb measles vaccine were given at 20 weeks of age, 4-6 weeks after the third dose of DTP, with no subsequent doses of DTP in girls, and no vitamin A in girls or boys before the second dose of measles vaccine at 9 months of age. Policy should change to increase the proportion of babies given BCG and oral polio vaccine at birth, and should recognize the important differences between BCG, DTP and measles vaccines produced by different manufacturers.

Iatrogenic injury and unexpected hospital death in the newborn

Neonates are unusually vulnerable to iatrogenic injury due to small body size, delicate tissues, and immature immune systems. Investigation of an unexpected neonatal death in the hospital should begin with a review of the medical record and discussion with medical staff involved in the patient׳s care. Postmortem investigation should include a complete and well-documented autopsy. Additional investigations, such as microbiological studies and chemical and toxicological studies of postmortem and antemortem fluid samples, may be crucial in arriving at a diagnosis. Causes of iatrogenic injury include birth trauma, medication errors and adverse drug effects, hospital-acquired infection, and medical device malfunction, incorrect placement, and misuse. Autopsy is an important tool for understanding the cause of an unexpected death, improving the quality of care, and providing closure to parents and family.

Patient safety in the context of neonatal intensive care: research and educational opportunities

Case reports and observational studies continue to report adverse events from medical errors. However, despite considerable attention to patient safety in the popular media, this topic is not a regular component of medical education, and much research needs to be carried out to understand the causes, consequences, and prevention of healthcare-related adverse events during neonatal intensive care. To address the knowledge gaps and to formulate a research and educational agenda in neonatology, the Eunice Kennedy Shriver National Institute of Child Health and Human Development invited a panel of experts to a workshop in August 2010. Patient safety issues discussed were the reasons for errors, including systems design, working conditions, and worker fatigue; a need to develop a "culture" of patient safety; the role of electronic medical records, information technology, and simulators in reducing errors; error disclosure practices; medicolegal concerns; and educational needs. Specific neonatology-related topics discussed were errors during resuscitation, mechanical ventilation, and performance of invasive procedures; medication errors including those associated with milk feedings; diagnostic errors; and misidentification of patients. This article provides an executive summary of the workshop.

Iatrogenic complications in the neonatal intensive care unit

With the introduction of novel technologies and approaches in neonatal care and the lack of appropriately designed and well-executed randomized clinical trials to investigate the impact of these interventions, iatrogenic complications have been increasingly seen in the neonatal intensive care unit. In addition, increased awareness and the introduction of more appropriate quality control measures have resulted in higher levels of suspicion about and increased recognition of complications associated with delivery of care. The incidence of complications also rises with the increased length of hospital stay and level of immaturity. Approximately half of the iatrogenic complications are related to medication errors. The other complications are due to nosocomial infections, insertion of invasive catheters, prolonged mechanical ventilation, administration of parenteral nutrition solution, skin damage and environmental complications. Adopting newer technologies and preventive measures might decrease these complications and improve outcomes. Quality improvement projects targeting areas for improvement are expected to build team spirit and further improve the outcomes. In addition, participation in national reporting systems will enhance education and provide an opportunity to compare outcomes with peer institutions.
