The 2013 Brazilian guidelines explicitly recommend against routine abdominal imaging and echo because of the low frequency of visceral lesions in adults with candidemia and recommend reserving imaging for those with persistently positive blood cultures or with clinical signs/symptoms suggestive of endocarditis/abdominal infection or clinical deterioration.17 The 2014 Japanese guidelines recommend ruling out chronic disseminated candidiasis in these patients with symptoms during the neutrophil recovery phase, but do not mention routinely imaging other patients. They do not address the role of echocardiography.18
Although physicians in the United Sates typically follow IDSA guidelines, abdominal US and echo were ordered routinely for patients with fungemia on the pediatric gastroenterology service at our institution, leading to higher medical costs and waste of medical resources. Our goals were to assess the current standard work for fungemia evaluation on this service, assess the impact of its deviation from current clinical guidelines, and redefine the standard work by (1) presenting current evidence to practitioners taking care of patients on this service, (2) providing a clinical pathway that allowed for variations where appropriate, and (3) providing a plan for pediatric fungemia management. Our SMART (Specific, Measurable, Attainable, Relevant and Timely) goal was to reduce overutilization of abdominal US and echo in pediatric patients with fungemia on the pediatric gastroenterology service by 50%.
Methods
Study, Setting, and Participants
We executed this quality improvement project at a quaternary care pediatric hospital affiliated with a school of medicine. The project scope consisted of inpatient pediatric patients with fungemia on the pediatric gastroenterology service admitted to the wards or pediatric critical care unit at this institution, along with the practitioners caring for these patients. The project was part of an institutional quality improvement initiative program. The quality improvement team included quality improvement experts from the departments of medicine and pediatrics, a pediatric resident and student, and physicians from the divisions of pediatric infectious disease, pediatric critical care, and pediatric gastroenterology. This study qualified for Institutional Review Board (IRB) exemption based on the University’s IRB stipulations.
Current Condition
Root cause analysis was performed by creating a process map of the current standard work and a fishbone diagram (Figure 1). We incorporated feedback from voice of the customer in the root cause analysis. In this analysis, the voice of the customer came from the bedside floor nurses, ultrasound clerk and sonographer, echo technician, cardiology fellow, and microbiology medical technician. We got their feedback on our process map, its accuracy and ways to expand, their thoughts on the problem and why we have this problem, and any solutions they could offer to help improve the problem. Some of the key points obtained were: echos were not routinely done on the floors and were not considered urgent as they often did not change management; the sonographer and those from the cardiology department felt imaging was often overutilized because of misconceptions and lack of available hospital guidelines. Suggested solutions included provider education with reference to Duke’s criteria and establishing a clinical pathway approved by all concerned departments.
Prior to education, we surveyed current practices of practitioners on teams caring for these patients, which included physicians of all levels (attendings, fellows, residents) as well as nurse practitioners and medical students from the department of pediatrics and divisions of pediatric gastroenterology, pediatric infectious disease, and pediatric critical care medicine.
