Effect of a positive pressure ventilation-refresher program on ventilation skill performance during simulated newborn resuscitation.

ABSTRACT:

Aim

Clinical staff highly proficient in neonatal resuscitation are essential to ensure prompt, effective positive pressure ventilation (PPV) for infants that do not breathe spontaneously after birth. However, it is well-documented that resuscitation competency is transient after standard training. We hypothesized that brief, repeated PPV psychomotor skill refresher training would improve PPV performance for newborn care nurses.

Methods

Subjects completed a blinded baseline and post PPV-skills assessment. Data on volume and rate for each ventilation was recorded. After baseline assessment, subjects completed PPV-Refreshers over 3 months consisting of psychomotor skill training using a newborn manikin with visual feedback. Subjects provided PPV until they could deliver ≥30 s of PPV meeting targets for volume (10-21 mL) and rate (40-60 ventilations per minute [vpm]). Baseline and post assessments were compared for total number PPV delivered, number target PPV delivered (volume 10-21 mL), mean volume and mean rate (Wilcoxon signed-rank test, median[IQR]).

Results

Twenty-six subjects were enrolled and completed a baseline assessment; 24 (92%) completed a post-assessment; 2 (8%) were lost to follow-up. Over 3 months, a mean 3.2 (range 1-6) PPV-Refreshers/subject were completed. Compared to baseline, subjects demonstrated significant improvement for total (57 [36-74] vs. 33 [26-46]; p = 0.0007) and target PPV (23 [13-23] vs. 11 [5-21]; p = 0.024), and a significant change in mean volume (mL) (11.5 [10.2-13] vs. 13.4 [11-16]; p = 0.02) and mean rate (vpm) (54 [45-61] vs. 40 [28-49]; p = 0.019).

Conclusions

A PPV-Refresher program with brief, repeated psychomotor skill practice significantly improved PPV performance with the greatest improvement in total PPV and target PPV. Additional investigation is warranted to determine optimal PPV-Refresher frequency.Registered at ClinicalTrials.gov #NCT02347241.

Project description:AimMaintaining neonatal resuscitation skills among health workers in low-resource settings will require continuous quality improvement efforts. We aimed to evaluate the effect of skill drills and feedback on neonatal resuscitation and the optimal number of skill drills required to maintain the ventilation skill in a simulated setting.MethodsAn observational study was conducted for a period of 3?months in a referral hospital of Nepal. Sixty nursing staffs were trained on Helping Babies Breathe (HBB) 2.0 and daily skill drills using a high-fidelity manikin. The high-fidelity manikin had different clinical case scenarios and provided feedback as "well done" or "improvement required" based on the ventilation performance. Adequate ventilation was defined as bag-and-mask ventilation at the rate of 40-60 breaths per minute. The effective ventilation was defined as adequate ventilation with a "well done" feedback. We assessed the correlation of the number of skill drills and clinical case scenario with adequate ventilation rate using Pearson's correlation. We assessed the correlation of the number of skill drills performed by each participant with effective ventilation using the Mann-Whitney test.ResultsAmong the total of 60 nursing staffs, all of them were competent with an average score of 12.73?±?1.09 out of 14 (p?<?0.001) on bag-and-mask ventilation skill checklist. Among the trained staffs, 47 staffs participated in daily skill drills who performed a total of 331 skill drills and 68.9% of the ventilations were done adequately. Among the 47 nursing staffs who performed the skill drills, 228 (68.9%) drills were conducted at a ventilation rate of 40-60 breaths per minute. There was no correlation in the adequate ventilation with the skill drill category (p?=?0.88) and the level of skill performed (p?=?0.28). Out of 47 participants performing the skill drills, 74.5% of them had done effective ventilation with a mean average of 8 skill drills (SD?±?4.78) (p value 0.032).ConclusionIn a simulated setting, participants who had an average skill drill of 8 in 3 months had effective ventilation. We demonstrated optimal skill drill sessions to maintain the neonatal resuscitation competency. Further evaluation will be required to validate the findings in a scale-up setting.

Project description:Intrapartum events leading to asphyxia at birth are among the leading causes of neonatal morbidity and mortality in Nepal. In response to this, the Nepal Ministry of Health and Population adopted Helping Babies Breathe (HBB) as a tool to improve neonatal resuscitation competencies. The effectiveness of HBB trainings has been well established. However, challenges remain in maintaining skills over time. Safa Sunaulo Nepal (SSN), with support from Latter-day Saint Charities (LDS Charities) designed an initiative for scaling up newborn resuscitation training and skills maintenance over time. This paper reports on the implementation of the SSN model of newborn resuscitation trainings and skill retention, and the changes in perinatal outcomes that occurred after the program. The program built capacity among facility-based trainers for the scale up and maintenance of resuscitation skills in 20 facilities in Madhesh Province, Nepal. A single external Mentor coached and assisted the facility-based trainers, provided general support, and monitored progress. Prospective outcome monitoring tracked changes in health metrics for a period of 14 months. Data was gathered on the neonatal health outcomes of 68,435 vaginal deliveries and 9,253 cesarean sections. Results indicate decreases in neonatal deaths under 24 hours of life (p<0.001), intrapartum stillbirths (p<0.001), and the number of sick newborns transferred from the maternity unit (p<0.001). During the program, facility-based trainers taught resuscitation skills to 231 medical personnel and supported ongoing skill retention. The SSN model for newborn resuscitation training and skills retention is a low-cost, evidence-based program focusing on facility-based trainers who are mentored and supported to scale-up and sustain resuscitation skills over time. Findings from the report are suggestive that the model had a substantial influence on critical neonatal outcomes. Future programs focused on improving neonatal outcomes may benefit by incorporating program elements of SSN model.

Project description:BACKGROUND:Effective positive pressure ventilation (PPV) of non-breathing newborns is crucial in facilitating cardio-respiratory adaptation at birth. Identifying predictors of death in newborns receiving PPV is important in order to facilitate preventative strategies. OBJECTIVE:The objective of this study was to determine the perinatal predictors of death including the quality of PPV administered among admitted newborns. METHODS:An observational study of admitted newborns who received PPV after birth was conducted. Research assistants observed all deliveries and recorded perinatal events on data collection forms. Measured heart rate (HR) and ventilation parameters were then compared between newborns who died and survivors. RESULTS:Newborns (n = 232) were studied between October 2014 and November 2016. Newborns who died (n = 53) compared to survivors (n = 179) had more fetal heart rate (FHRT) abnormalities (12/53 vs 19/179; p = 0.03); lower initial HR (<100 beats/minute) at start of PPV (44/48 vs 77/139; p<0.001); and a longer time for HR to increase >100 beats/minute from birth (180 vs 149 seconds; p = 0.07). Newborns who died compared to survivors took longer time (14 vs 4 seconds; p = 0.008) and more inflations (7 vs 3; p = 0.006) to achieve an expired volume (Vt) of 6 ml/kg, respectively. Median delivered Vt during the first 60 seconds of PPV was less in newborns who died compared to survivors (5 vs 6 ml/kg; p = 0.12). Newborns who died proceeded to severe encephalopathy (15/31 vs 1/59; p<0.001) compared to survivors. CONCLUSION:Depressed newborns who proceeded to death compared to survivors, exhibited delayed HR response to PPV which may partly reflect FHRT abnormalities related to interruption of placental blood flow, and/or a timely delay in establishing adequate Vt. Depressed newborns progressed to moderate/severe encephalopathy. Improving FHRT monitoring to identify fetuses at risk for expedited delivery, coupled with optimizing delivery room PPV might decrease mortality in this setting.

Project description:ObjectivesGlobally, perinatal mortality remains high, especially in sub-Saharan countries, mainly because of inadequate obstetric and newborn care. Helping Babies Breathe (HBB) resuscitation training as part of a continuous quality improvement (CQI) programme may improve outcomes. The aim of this study was to describe observed changes in perinatal survival during a 6-year period, while adjusting for relevant perinatal risk factors.SettingDelivery rooms and operating theatre in a rural referral hospital in northern-central Tanzania providing comprehensive obstetric and basic newborn care 24 hours a day. The hospital serves approximately 2 million people comprising low social-economic status.ParticipantsAll newborns (n=31 122) born in the hospital from February 2010 through January 2017; 4893 were born in the 1-year baseline period (February 2010 through January 2011), 26 229 in the following CQI period.InterventionsThe HBB CQI project, including frequent HBB training, was implemented from February 2011. This is a quality assessment analysis of prospectively collected observational data including patient, process and outcome measures of every delivery. Logistic regression modelling was used to construct risk-adjusted variable life adjusted display (VLAD) and cumulative sum (CUSUM) plots to monitor changes in perinatal survival (primary outcome).ResultsDuring the 6-year CQI period, the unadjusted number of extra lives saved according to the VLAD plot was 150 despite more women admitted with pregnancy and labour complications and more caesarean deliveries. After adjusting for these risk factors, the risk-adjusted VLAD plot indicated that an estimated 250 extra lives were saved. The risk-adjusted CUSUM plot confirmed a persistent and steady increase in perinatal survival.ConclusionsThe risk-adjusted statistical process control methods indicate significant improvement in perinatal survival after initiation of the HBB CQI project with continuous focus on newborn resuscitation training during the period, despite a concomitant increase in high-risk deliveries. Risk-adjusted VLAD and CUSUM are useful methods to quantify, illustrate and demonstrate persistent changes in outcome over time.

Project description:IntroductionThere is an increasing interest in biphasic positive airway pressure with spontaneous breathing (BIPAP+SBmean), which is a combination of time-cycled controlled breaths at two levels of continuous positive airway pressure (BIPAP+SBcontrolled) and non-assisted spontaneous breathing (BIPAP+SBspont), in the early phase of acute lung injury (ALI). However, pressure support ventilation (PSV) remains the most commonly used mode of assisted ventilation. To date, the effects of BIPAP+SBmean and PSV on regional lung aeration and ventilation during ALI are only poorly defined.MethodsIn 10 anesthetized juvenile pigs, ALI was induced by surfactant depletion. BIPAP+SBmean and PSV were performed in a random sequence (1 h each) at comparable mean airway pressures and minute volumes. Gas exchange, hemodynamics, and inspiratory effort were determined and dynamic computed tomography scans obtained. Aeration and ventilation were calculated in four zones along the ventral-dorsal axis at lung apex, hilum and base.ResultsCompared to PSV, BIPAP+SBmean resulted in: 1) lower mean tidal volume, comparable oxygenation and hemodynamics, and increased PaCO2 and inspiratory effort; 2) less nonaerated areas at end-expiration; 3) decreased tidal hyperaeration and re-aeration; 4) similar distributions of ventilation. During BIPAP+SBmean: i) BIPAP+SBspont had lower tidal volumes and higher rates than BIPAP+SBcontrolled; ii) BIPAP+SBspont and BIPAP+SBcontrolled had similar distributions of ventilation and aeration; iii) BIPAP+SBcontrolled resulted in increased tidal re-aeration and hyperareation, compared to PSV. BIPAP+SBspont showed an opposite pattern.ConclusionsIn this model of ALI, the reduction of tidal re-aeration and hyperaeration during BIPAP+SBmean compared to PSV is not due to decreased nonaerated areas at end-expiration or different distribution of ventilation, but to lower tidal volumes during BIPAP+SBspont. The ratio between spontaneous to controlled breaths seems to play a pivotal role in reducing tidal re-aeration and hyperaeration during BIPAP+SBmean.
