Reducing peripherally inserted central catheters in the neonatal intensive care unit.

OBJECTIVE: Our objective was to safely reduce the number of peripherally inserted central catheters (PICCs) inserted in infants with umbilical venous catheter using quality improvement methods. STUDY DESIGN: In a tertiary neonatal intensive care unit, a questionnaire designed to prompt critical thinking around the decision to place a PICC, along with an updated standardized feeding guideline was introduced. PICC insertion in 86 infants with umbilical venous catheter (pre intervention) with birth weight 1000-1500 g were compared with 115 infants (post intervention) using Fisher's exact test. RESULTS: PICC lines inserted after the intervention decreased by 37.5% (67/86; 77.9% vs 56/115; 48.7%; P<0.001). The proportion of central line-associated blood stream infection were 2.49 vs 2.82/1000 umbilical venous catheter days; P=0.91 in the two epochs, respectively. CONCLUSION: Quality improvement methodology was successful in significantly reducing the number of PICCs inserted without an increase in central line-associated blood stream infection.

Emergence of community-associated methicillin-resistant Staphylococcus aureus strains in the neonatal intensive care unit: an infection prevention and patient safety challenge.

Methicillin-resistant Staphylococcus aureus (MRSA) infections cause significant morbidity and mortality in neonatal intensive care units (NICUs). We characterized the clinical and molecular epidemiology of MRSA strains colonizing NICU patients. Nasal MRSA isolates (n = 250, from 96 NICU patients) recovered through active surveillance from 2009 to 2014 were characterized with staphylococcal cassette chromosome mec (SCCmec) typing and detection of mupA (marker of high-level mupirocin resistance) and qacA/B (marker associated with chlorhexidine resistance). Factors associated with community-associated (CA-) or healthcare-associated (HA-) MRSA were evaluated. The overall prevalence of MRSA nasal colonization was 3.9%. Of 96 neonates in our retrospective cohort, 60 (63%) were colonized with CA-MRSA strains and 35 (36%) were colonized with HA-MRSA strains. Patients colonized with HA-MRSA were more likely to develop MRSA infections than patients colonized with CA-MRSA (13/35, 37% versus 8/60, 13%; p 0.007), although the interval from colonization to infection was shorter in CA-MRSA-colonized infants (median 0 days, range -1 to 4 versus HA-MRSA-colonized infants, 7 days, -1 to 43; p 0.005). Maternal peripartum antibiotics were associated with CA-MRSA colonization (adjusted odds ratio (aOR) 8.7; 95% CI 1.7-45.0); intubation and surgical procedures were associated with HA-MRSA colonization (aOR 7.8; 95% CI 1.3-47.6 and aOR 6.0; 95% CI 1.4-24.4, respectively). Mupirocin- and chlorhexidine-resistant MRSA was isolated from four and eight patients, respectively; carriage of a mupirocin-resistant strain precluded decolonization. CA-MRSA strains are prominent in the NICU and associated with distinct risk factors. Given community reservoirs for MRSA acquisition and transmission, novel infection prevention strategies are needed.

Use of web-based data collection to evaluate analgesic administration and the decision for surgery in horses with colic.

REASONS FOR PERFORMING STUDY: There is no current veterinary information with regard to data entry on a website. We therefore completed a prospective study on use of analgesics in relation to the need for abdominal surgery using a web-based survey instrument. OBJECTIVES: To establish an internet-based data entry system that could be used to record prospective data on horses with colic. HYPOTHESIS: Failure of horses to respond to the initial administration of an analgesic is an indicator of the need for abdominal surgery. METHODS: A survey was developed to determine if the response to administration of an analgesic during a veterinarian's first examination of a horse with colic was related to the need for surgery. Veterinarians were contacted via AAEP and ECN listservs requesting submission of cases using a log-in system at a data entry website. The survey was completed by submission of a data entry page. RESULTS: Twenty-seven veterinarians submitted details of 119 cases of colic, 28 of which required surgery. The need for surgery was significantly associated with moderate or severe pain observed during the first examination compared to mild or no pain, and with constant pain or return of pain after administration of one or more analgesics and the need to administer a second analgesic treatment. Abnormal findings on rectal examination were not associated with the need for surgery, whereas total absence or decrease of intestinal sounds was significantly related to the odds that surgery was needed. The web-based data collection was successful in collecting all data points on the survey for each case. CONCLUSIONS: This study reinforced veterinarians' use of response to therapy as a way to determine the need for abdominal surgery. POTENTIAL RELEVANCE: When a specific diagnosis has not been made, lack of response or resumption of colic after analgesic administration should be considered as an indicator of the need for surgery. Web-based collection of data allows veterinary practitioners to participate in clinical research by providing prospective data.

Nosocomial primary bloodstream infections in intensive care unit patients in a nonteaching community medical center: a 21-month prospective study.

All patients admitted to the medical and surgical intensive care units of a 500-bed nonteaching suburban hospital were followed prospectively for the occurrence of nosocomial primary bloodstream infections for 21 months. The incidence of primary bloodstream infection was 38 (1%) of 3163 patients; among patients with central venous catheters, it was 34 (4%) of 920 patients, or 4.0 infections per 1000 catheter-days. Ventilator-associated pneumonia, congestive heart failure, and each intravascular catheter inserted were independently associated with the development of a nosocomial primary bloodstream infection. Among infected patients, the crude mortality rate was 53%, and these patients had longer stays in intensive care units and the hospital than did uninfected patients. Bloodstream infection, however, was not an independent risk factor for death. The incidence, risk factors, and serious outcomes of bloodstream infections in a nonteaching community hospital were similar to those seen in tertiary-care teaching hospitals.
