Multisite Quality Improvement Program Within the Project ECHO Diabetes Remote Network.

BACKGROUND: The telementoring Project ECHO (Extension for Community Healthcare Outcomes) model has been shown to improve disease management in diabetes in many underserved communities. The authors aim to evaluate if ECHO could also be an effective tool for quality improvement (QI) of diabetes care in these communities. METHODS: Thirteen clinics in underserved communities in California and Florida participating in Project ECHO Diabetes were recruited for a 12-month QI program. The program provided weekly tele-education sessions, including a didactic presentation and case-based discussion. In addition, clinics chose their own set of quality measures to improve and met remotely to discuss their efforts, successes, and setbacks every quarter with mentorship from QI experts. RESULTS: Of the 31 QI initiatives attempted by different clinics, all had either made improvements (25 initiatives, 80.6%) or were in the process of making improvements (6 initiatives, 19.4%) in structural, process, and outcome measures. Examples of these measures include whether clinics have protocols to identify high-risk patients (structure), numbers of continuous glucose monitor prescriptions submitted by the clinics (process), and percentage of patients with diabetes whose most recent HbA1c are > 9% (outcome). For one measure, 40.0% of the clinics had achieved a higher percentage of cumulative HbA1c measurement in the third quarter of the year, compared to the fourth quarter in the previous year. The cost of QI implementation varied widely due to different number of personnel involved across sites. CONCLUSION: A QI program delivered via Project ECHO Diabetes can facilitate quality improvements in underserved communities.

Parent Perspectives in Shared Decision-Making for Children With Medical Complexity.

OBJECTIVE: Shared decision-making (SDM) may improve outcomes for children with medical complexity (CMC). CMC have lower rates of SDM than other children, but little is known about how to improve SDM for CMC. The objective of this study is to describe parent perspectives of SDM for CMC and identify opportunities to improve elements of SDM specific to this vulnerable population. METHODS: Interviews with parents of CMC explored SDM preferences and experiences. Eligible parents were ≥18 years old, English- or Spanish-speaking, with a CMC <12 years old. Interviews were recorded, transcribed, and analyzed by independent coders for shared themes using modified grounded theory. Codes were developed using an iterative process, beginning with open-coding of a subset of transcripts followed by discussion with all team members, and distillation into preliminary codes. Subsequent coding reviews were conducted until no new themes emerged and existing themes were fully explored. RESULTS: We conducted interviews with 32 parents (27 in English, mean parent age 34 years, standard deviation = 7; mean child age 4 years, standard deviation = 4; 50% with household income <$50,000, 47% with low health literacy) in inpatient and outpatient settings. Three categories of themes emerged: participant, knowledge, and context. Key opportunities to improve SDM included: providing a shared decision timeline, purposefully integrating patient preferences and values, and addressing uncertainty in decisions. CONCLUSION: Our results provide insight into parent experiences with SDM for CMC. We identified unique opportunities to improve SDM for CMC that will inform future research and interventions to improve SDM for CMC.

Nursing attitudes towards continuous capnographic monitoring of floor patients.

INTRODUCTION: Nurses' perceptions of the utility of capnography monitoring are inconsistent in previous studies. We sought to outline the limitations of a uniform education effort in bringing about consistent views of capnography among nurses. METHODS: A survey was administered to 22 nurses in three subacute care floors participating in a pragmatic clinical trial employing capnography monitoring in a large, urban tertiary care hospital. A 5-point Likert scale was used to assess the value and acceptance nurses ascribed to the practice. Means and SD were calculated for each response. RESULTS: Survey results indicated inconsistency in the valuation of capnography, coupled with varying degrees of acceptance of its use. The mean for the level of perceived impact of capnography use on patient safety was 3.86, yet the perceived risk of removing capnography was represented by a mean of 2.57. The levels of urgency attached to apnoea alarms (mean 3.57, SD 1.57) were lower than those for alarms for oxygen saturation violations (mean 3.67, SD 1.32). The necessity for pulse oximetry monitoring was perceived as much higher than that for capnography monitoring (mean 1.76, SD 1.34), where '1' represented pulse oximetry as more necessary and '5' represented capnography as more necessary. CONCLUSIONS: Nursing acceptance of capnography monitoring is a difficult endpoint to achieve. There is a need for better accounting for the external and internal influences on nurse perceptions and values to have greater success with the implementation of similar monitoring.

Development of a NeuroNICU with a Broader Focus on All Newborns at Risk of Brain Injury: The First 2 Years.

OBJECTIVE: Many critically ill neonates have an existing brain injury or are at risk of neurologic injury. We developed a "NeuroNICU" (neurologic neonatal intensive care unit) to better provide neurologically focused intensive care. STUDY DESIGN: Demographic and clinical variables, services delivered, and patient outcomes were recorded in a prospective database for all neonates admitted to the NeuroNICU between April 23, 2013, and June 25, 2015. RESULTS: In total, 546 neonates were admitted to the NeuroNICU representing 32% of all NICU admissions. The most common admission diagnoses were congenital heart disease (30%), extreme prematurity (18%), seizures (10%), and hypoxic-ischemic encephalopathy (9%). Neuromonitoring was common, with near-infrared spectroscopy used in 69%, amplitude-integrated electroencephalography (EEG) in 45%, and continuous video EEG in 35%. Overall, 43% received neurology or neurosurgery consultation. Death prior to hospital discharge occurred in 11%. Among survivors, 87% were referred for developmental follow-up, and among those with a primary neurologic diagnosis 57% were referred for neurology or neurosurgical follow-up. CONCLUSION: The NeuroNICU-admitted newborns with or at risk of brain injury comprise a high percentage of NICU volume; 38% had primary neurologic diagnoses, whereas 62% had medical diagnoses. We found many opportunities to provide brain focused intensive care, impacting a substantial proportion of newborns in our NICU.

Improving the Identification of Neonatal Encephalopathy: Utility of a Web-Based Video Tool.

Objective This study tested the effectiveness of a video teaching tool in improving identification and classification of encephalopathy in infants. Study Design We developed an innovative video teaching tool to help clinicians improve their skills in interpreting the neonatal neurological examination for grading encephalopathy. Pediatric residents were shown 1-minute video clips demonstrating exam findings in normal neonates and neonates with various degrees of encephalopathy. Findings from five domains were demonstrated: spontaneous activity, level of alertness, posture/tone, reflexes, and autonomic responses. After each clip, subjects were asked to identify whether the exam finding was normal or consistent with mild, moderate, or severe abnormality. Subjects were then directed to a web-based teaching toolkit, containing a compilation of videos demonstrating normal and abnormal findings on the neonatal neurological examination. Immediately after training, subjects underwent posttesting, again identifying exam findings as normal, mild, moderate, or severe abnormality. Results Residents improved in their overall ability to identify and classify neonatal encephalopathy after viewing the teaching tool. In particular, the identification of abnormal spontaneous activity, reflexes, and autonomic responses were most improved. Conclusion This pretest/posttest evaluation of an educational tool demonstrates that after viewing our toolkit, pediatric residents were able to improve their overall ability to detect neonatal encephalopathy.

Plasma vasopressin concentrations positively predict cerebrospinal fluid vasopressin concentrations in human neonates.

Central arginine vasopressin (AVP) plays a critical role in mammalian social behavior and has been hypothesized to be a biomarker of certain human neurodevelopmental disorders, including autism. However, opportunities to collect post-mortem brain tissue or cerebrospinal fluid (CSF) from children are extremely limited, and the use of less invasive peripheral assessments (e.g., blood, urine, or saliva) of AVP as a proxy for more invasive central measures has not been well validated. Further, almost nothing is known about AVP biology in very young infants. Therefore in the present study we concomitantly collected basal CSF and plasma samples from N = 20 neonates undergoing clinical sepsis evaluation (all were sepsis negative) and quantified AVP concentrations via well-validated enzyme-immunoassay methodology. Plasma AVP concentrations significantly and positively predicted CSF AVP concentrations (r = 0.73, p = 0.0021), and this relationship persisted when variance attributed to sex, gestational age, and sample collection time was controlled for in the statistical model (r = 0.75, p = 0.0047). These findings provide preliminary support for the use of basal plasma AVP measurement as a proxy for basal brain AVP activity in pediatric populations. Future studies are now required to determine the relationship between behavioral measures and AVP concentrations in both central and peripheral compartments in young infants and older children.

Neonatal CSF oxytocin levels are associated with parent report of infant soothability and sociability.

Oxytocin (OT) has been linked to social behavior in rodents, non-human primates, and adult humans, but almost nothing is known about brain OT activity in human newborns or its impact on social development. To better understand the role of OT biology in human social functioning, a multi-disciplinary, longitudinal study was conducted. Cerebral spinal fluid (CSF) OT levels from 18 human neonates were evaluated and examined in relationship to social-seeking behavior at term, at 3 months, and at 6 months of age. Higher neonatal CSF OT levels were consistently associated with solicitation of parental soothing and interest in social engagement with others. This is the first study to link CSF OT levels to normative human social functioning. Research is now required to test whether early OT levels serve as a biomarker for subsequent social abnormalities.

Capability of 11 antipneumococcal antibiotics to select for resistance by multistep and single-step methodologies.

Testing of 12 pneumococcal strains with differing resistotypes [including tet(M) positive] showed that tigecycline, amoxicillin-clavulanate, imipenem, and ceftriaxone did not select for resistant clones after 50 sequential subcultures. By comparison, azithromycin, clarithromycin, clindamycin, telithromycin, levofloxacin, moxifloxacin, and gemifloxacin did show resistant clones. Tigecycline also yielded a low frequency of resistance in single-step tests compared to all beta-lactams, macrolides/ketolides, and quinolones tested.

Antipneumococcal activities of two novel macrolides, GW 773546 and GW 708408, compared with those of erythromycin, azithromycin, clarithromycin, clindamycin, and telithromycin.

The MICs of GW 773546, GW 708408, and telithromycin for 164 macrolide-susceptible and 161 macrolide-resistant pneumococci were low. The MICs of GW 773546, GW 708408, and telithromycin for macrolide-resistant strains were similar, irrespective of the resistance genotypes of the strains. Clindamycin was active against all macrolide-resistant strains except those with erm(B) and one strain with a 23S rRNA mutation. GW 773546, GW 708408, and telithromycin at two times their MICs were bactericidal after 24 h for 7 to 8 of 12 strains. Serial passages of 12 strains in the presence of sub-MICs yielded 54 mutants, 29 of which had changes in the L4 or L22 protein or the 23S rRNA sequence. Among the macrolide-susceptible strains, resistant mutants developed most rapidly after passage in the presence of clindamycin, GW 773546, erythromycin, azithromycin, and clarithromycin and slowest after passage in the presence of GW 708408 and telithromycin. Selection of strains for which MICs were >/=0.5 microg/ml from susceptible parents occurred only with erythromycin, azithromycin, clarithromycin, and clindamycin; 36 resistant clones from susceptible parent strains had changes in the sequences of the L4 or L22 protein or 23S rRNA. No mef(E) strains yielded resistant clones after passage in the presence of erythromycin and azithromycin. Selection with GW 773546, GW 708408, telithromycin, and clindamycin in two mef(E) strains did not raise the erythromycin, azithromycin, and clarithromycin MICs more than twofold. There were no change in the ribosomal protein (L4 or L22) or 23S rRNA sequences for 15 of 18 mutants selected for macrolide resistance; 3 mutants had changes in the L22-protein sequence. GW 773546, GW 708408, and telithromycin selected clones for which MICs were 0.03 to >2.0 microg/ml. Single-step studies showed mutation frequencies <5.0 x 10(-10) to 3.5 x 10(-7) for GW 773546, GW 708408, and telithromycin for macrolide-susceptible strains and 1.1 x 10(-7) to >4.3 x 10(-3) for resistant strains. The postantibiotic effects of GW 773546, GW 708408, and telithromycin were 2.4 to 9.8 h.

Activity of cefditoren against respiratory pathogens.

The activity of cefditoren and six other cephalosporins was tested against 250 pneumococci, including strains resistant to macrolides and quinolones. Cefditoren gave the lowest MICs, with MIC(50) and MIC(90) values of < or =0.016/0.03, 0.125/0.5 and 0.5/2.0 mg/L for penicillin-susceptible, -intermediate and -resistant pneumococci, respectively. A time-kill study of 12 pneumococcal strains with varying drug susceptibilities showed that cefditoren, at 2 x MIC, gave 99% killing of all strains after 12 h, with 99.9% killing after 24 h. Other cephalosporins gave similar kill kinetics but at higher concentrations. Against 160 Haemophilus influenzae, cefditoren had the lowest MICs (MIC(50) and MIC(90) both < or =0.016 mg/L), irrespective of beta-lactamase production. Time-kill studies of cefditoren compared with five other oral cephalosporins showed that cefditoren, at 8 x MIC, was bactericidal against 8/9 strains and gave 90% killing of all strains at the MIC after 12 h. Activity was bactericidal (99.9% killing) after 24 h with all drugs tested. Multistep studies of four penicillin-susceptible, four penicillin-intermediate and four penicillin-resistant strains showed that cefditoren, co-amoxiclav and cefprozil did not select for resistant mutants after 50 subcultures, compared with cefuroxime and azithromycin, where resistant mutants were selected in two and nine strains, respectively. Single-step mutation studies showed that cefditoren, at the MIC, had the lowest frequency of spontaneous mutants compared with other drugs.

Antipneumococcal activity of AZD2563, a new oxazolidinone, compared with nine other agents.

The in vitro activity of AZD2563, a new oxazolidinone, was compared with that of linezolid, vancomycin, quinupristin/dalfopristin, amoxicillin, levofloxacin, penicillin, erythromycin, azithromycin and clindamycin against a range of pneumococci by microdilution and time-kill studies. Against 300 pneumococci (99 penicillin susceptible, 86 penicillin intermediate, 115 penicillin resistant, 185 erythromycin resistant, 35 quinolone resistant), both oxazolidinones remained active against isolates less susceptible to other agents, with MICs ranging between 0.125 and 2 mg/L; AZD2563 MICs were generally one dilution lower than those of linezolid. Both quinupristin/dalfopristin and vancomycin were active against all groups (MIC ranges 0.125-2 and 0.125-0.25 mg/L, respectively). Apart from 35 isolates with levofloxacin MICs > or= 8 mg/L, levofloxacin MICs were < or =0.25-4 mg/L. MICs of amoxicillin and erythromycin rose with penicillin G MICs; most macrolide-resistant isolates were either penicillin-intermediate or -resistant. Against 16 organisms with differing beta-lactam, macrolide and quinolone MICs, time-kill studies showed that AZD2563 was bactericidal (99.9% killing) at 4 x MIC against nine strains at 24 h, with 90% killing of all 16 strains at 2 x MIC after 12 h. Similar results were obtained with linezolid. Both oxazolidinones were bacteriostatic at the MIC against all 16 strains. Amoxicillin, levofloxacin and vancomycin, at 2 x MIC, were bactericidal against 15 of the 16 strains after 24 h. Quinupristin/dalfopristin yielded the most rapid killing, with bactericidal activity against 13 of 16 strains at the MIC after 3 h and against 15 strains at 2 x MIC after 24 h. Erythromycin was bactericidal against all 10 strains with MICs < or= 8 mg/L at 4 x MIC after 24 h.
