Accuracy of Transcutaneous CO2 Values Compared With Arterial and Capillary Blood Gases.

BACKGROUND: Transcutaneous monitors are utilized to monitor a patient's respiratory status. Some patients have similar values when comparing transcutaneous carbon dioxide (PtcCO2 ) values with blood gas analysis, whereas others show extreme variability. A retrospective review of data was performed to determine how accurately PtcCO2 correlated with CO2 values obtained by arterial blood gas (ABG) or capillary blood gas. METHODS: To determine whether PtcCO2 values correlated with ABG or capillary blood gas values, subjects' records were retrospectively reviewed. Data collected included the PtcCO2 value at the time of blood gas procurement and the ABG or capillary blood gas PCO2 value. Agreement of pairs of methods (ABG vs PtcCO2 and capillary blood gas vs PtcCO2 ) was assessed with the Bland-Altman approach with limits of agreement estimated with a mixed model to account for serial measurements per subject. RESULTS: A total of 912 pairs of ABG/PtcCO2 values on 54 subjects and 307 pairs of capillary blood gas/PtcCO2 values on 34 subjects were analyzed. The PCO2 range for ABG was 24-106 mm Hg, and PtcCO2 values were 27-133 mm Hg. The PCO2 range for capillary blood gas was 29-108 mm Hg, and PtcCO2 values were 30-103 mm Hg. For ABG/PtcCO2 comparisons, the Pearson correlation coefficient was 0.82, 95% CI was 0.80-0.84, and P was <.001. For capillary blood gas/PtcCO2 comparisons, the Pearson correlation coefficient was 0.77, 95% CI was 0.72-0.81, and P was <.001. For ABG/PtcCO2 , the estimated difference ± SD was -6.79 ± 7.62 mm Hg, and limits of agreement were -22.03 to 8.45. For capillary blood gas/PtcCO2 , the estimated difference ± SD was -1.61 ± 7.64 mm Hg, and limits of agreement were -16.88 to 13.66. The repeatability coefficient was about 30 mm Hg. CONCLUSIONS: Based on these data, capillary blood gas comparisons showed less variation and a slightly lower correlation with PtcCO2 than did ABG comparisons. After accounting for serial measurements per patient, due to the wide limits of agreement and poor repeatability, the utility of relying on PtcCO2 readings for this purpose is questionable.

Evaluating Evidence-Based Practice Knowledge and Beliefs Through the e-Learning EBP Academy.

BACKGROUND: This research examined evidence-based practice (EBP) knowledge and beliefs before and after a 3-month e-learning program was implemented to build EBP capacity at a large children's hospital. METHOD: Ten clinicians completed the development, implementation, and evaluation of the e-learning education, comprising phase one. Revision and participation by 41 clinicians followed in phase two. Participants in both phases completed the EBP Beliefs and Implementation Scales preintervention, postintervention, and 6 months after postintervention. RESULTS: EBP beliefs and implementation increased immediately and 6 months after postintervention, with statistically significant increases in both phases. Participants in both phases applied knowledge by completing mentor-supported EBP projects. CONCLUSION: Although EBP beliefs and implementation scores increased and e-learning provided flexibility for clinician participation, challenges arose, resulting in lower-than-expected completion. Subsequent revisions resulted in hybrid education, integrating classroom and e-learning with project mentoring. This funded e-learning research contributes knowledge to the growing specialty of professional development. J Contin Educ Nurs. 2017;48(7):304-311.

Implementation of a ß-Agonist/Airway Clearance Protocol in a Pediatric ICU.

BACKGROUND: Respiratory therapist (RT)-driven protocols have been in use for over 30 years. Protocols have been reported to decrease unnecessary or harmful therapy, health-care costs, and hospital stay. This study represents the evaluation of an original respiratory care protocol in the pediatric ICU at Arkansas Children's Hospital for ß-agonist and airway clearance interventions where one did not exist. METHODS: This project was composed of 2 parts: a survey administered to RTs and licensed independent practitioners and a retrospective review of outcome data comparing a therapist-driven ß-agonist/airway clearance protocol with physician-directed respiratory care ordering in a patient population admitted for acute respiratory failure. RESULTS: Acceptance of the protocol was evident in the survey responses because overall perceptions surrounding the implementation of the ß-agonist/airway clearance protocol were positive, and responders perceived that the protocol implementation elevated the status and increased the value of respiratory therapists. For the comparison of physician-directed orders with therapist-driven protocols, there were no significant differences between pre- and post-intervention groups for mean age, sex, mean daily acuity, or mean weighted daily acuity (P = .33, .19, >.99, and .79, respectively). There were also no differences in pediatric index of mortality 2, pediatric index of mortality 2 rate of mortality, pediatric risk of mortality 3 probability of death, and pediatric risk of mortality 3 scores (P = .63, .56, .19, and .44, respectively) between the 2 groups. When comparing physician-directed orders to therapist-driven protocols, all outcome measures (length of stay, ß-agonist therapies, airway clearance therapies, and ventilator days) showed statistically and clinically important reductions, adjusting for subject characteristics (P < .001) for the therapist-driven protocol group. CONCLUSIONS: In this institution, implementation of a ß-agonist/airway clearance protocol resulted in significant reductions of subject interventions and improved outcomes by decreasing length of stay and ventilator days as well as contributing information where clinical evidence is scant, specifically the pediatric ICU.

Quality Improvement Project to Improve Timeliness Between Bronchodilator Treatments from Emergency Department to Medical Wards.

BACKGROUND: Quality improvement methodology was applied to study sporadic reports that patients with asthma were not given bronchodilator treatments or assessed within an appropriate time frame when they were admitted from the emergency department to the medical ward. The goal was to increase the number of patients who had an interval between emergency department assessment/bronchodilator treatment and medical ward assessment/treatment of <120 min. METHODS: A flow chart diagram, a fishbone diagram, data collection, intervention implementation, and data monitoring and analysis were used in this study. Data were collected on a pre-test of change cohort of 227 subjects with asthma from January 2013 to March 2014. A test of change adding a Q2H respiratory therapist assessment and as needed bronchodilator treatment order while the subject was in the emergency department was implemented during May of 2014. These data were compared with a post-test of change cohort of 278 subjects with asthma from May 2014 to July 2015. Data collection for both cohorts included the time from the last assessment/bronchodilator treatment in the emergency department to emergency department discharge, the time from emergency department discharge to assessment/treatment in the medical ward, and the sum of these 2 time periods. Mean times (minutes) were noted, and comparisons were made using 2-tailed independent t tests with significance set at P < .05. Mean monthly times were also compared in process control charts. RESULTS: There was a 124% increase noted in the percentage of subjects who received bronchodilator treatment within 120 min, a 53% increase within 180 min, and a 19% increase within 240 min. The interval time between treatments decreased 21%. CONCLUSIONS: Through quality improvement methodology, the group was able to significantly decrease the time between the last assessment/bronchodilator treatment in the emergency department and the first assessment/treatment in the medical ward for subjects with asthma. Moreover, improvement was seen in all studied parameters despite similar volumes in emergency department visits.

Complications with utilization of positive-pressure devices in a young man with duchenne muscular dystrophy.

Because of the progressive muscle weakness they experience, patients with Duchenne muscular dystrophy frequently utilize positive-pressure devices to maintain adequate bronchial hygiene and ventilation. This case illustrates the course of a 19-y-old male who presented with a perforated right tympanic membrane (TM) following the use of these devices. Perforation of the TM while utilizing positive-pressure devices is a rarely reported event. A challenging aspect in this case was balancing the reduction of pressures and maintaining adequate ventilation while at the same time allowing the TM to heal.

Analysis of STAT laboratory turnaround times before and after conversion of the hospital information system.

BACKGROUND: Modern electronic health record systems (EHRS) reportedly offer advantages including improved quality, error prevention, cost reduction, and increased efficiency. This project reviewed the impact on specimen turnaround times (TAT) and percent compliance for specimens processed in a STAT laboratory after implementation of an upgraded EHRS. METHODS: Before EHRS implementation, laboratory personnel received instruction and training for specimen processing. One laboratory member per shift received additional training. TAT and percent compliance data sampling occurred 4 times monthly for 13 months post-conversion and were compared with the mean of data collected for 3 months pre-conversion. Percent compliance was gauged using a benchmark of reporting 95% of all specimens within 7 min from receipt. RESULTS: Control charts were constructed for TAT and percent compliance with control limits set at 2 SD and applied continuously through the data collection period. TAT recovered to pre-conversion levels by the 6th month post-conversion. Percent compliance consistently returned to pre-conversion levels by the 10th month post-conversion. Statistical analyses revealed the TAT were significantly longer for 3 months post-conversion (P < .001) compared with pre-conversion levels. Statistical significance was not observed for subsequent groups. Percent compliance results were significantly lower for 6 months post-conversion (P < .001). Statistical significance was not observed for subsequent groups. CONCLUSIONS: Extensive efforts were made to train and prepare personnel for challenges expected after the EHRS upgrade. Specific causes identified with the upgraded EHRS included multiple issues involving personnel and the EHRS. These data suggest that system and user issues contributed to delays in returning to pre-conversion TAT and percent compliance levels following the upgrade in the EHRS.
