Post-transport TOPS score as a predictive marker of mortality among transported neonates and its comparative analysis with SNAP-II PE
Aim: Multiple parameters are available to predict the outcome of critically sick neonates admitted in neonatal intensive care unit (NICU). Main aim of the study is to validate the role of TOPS, especially the post-transport TOPS score as a simplified assessment of neonatal acute physiology in predicting mortality among transported neonates admitted at level III NICU. Also, to compare the efficiency of post transport TOPS score with SNAP II PE in predicting mortality.
Methods: A prospective study carried out with 85 neonates transported from various primary health care centres to level III NICU. Physiological status of the neonates was assessed with the help of pre and post transport TOPS scores. Post-transport TOPS score was recorded immediately after the admission and SNAP II PE within 24 h of admission at level III NICU. Receiver operating characteristics analysis was performed to observe the mortality prediction efficiency of TOPS score and was compared with SNAP II PE.
Results: 64 neonates were died due to asphyxia and preterm birth (32%) related complications. Strong significant association with the mortality rate was found between the total post transport TOPS score (0.001) and SNAP II PE (0.003). The AUC, sensitivity and specificity of post transport TOPS score for a cut-off value ≤7 were 0.900, 87.5% and 80% and significant (<0.001) and for SNAP II PE for a cut-off value >12 were 0.913, 75.5% and 100% and is significant (<0.001).
Conclusion: TOPS score, especially the post transport TOPS score has an equally good prediction capacity of mortality similar like SNAP II PE among mobilised critically ill neonates. Hence, the TOPS score can be used as a simple and effective method to predict mortality risk among transported neonates immediately after admission at level III NICU.
Prognostic role of TOPS in ambulance-transferred neonates in a low-resource setting: a retrospective observational study
Background: Assessing the severity of transferred neonates at admission can improve resource allocation. This study evaluated the role of TOPS (illness severity score including temperature, oxygen saturation, skin perfusion and blood sugar) in predicting mortality in neonates transferred by ambulance in a low-resource setting.
Methods: The study was conducted at Beira Central Hospital (Mozambique). Infants who were transferred by ambulance to the Neonatal Intensive Care Unit between 16th June and 16th October 2021 were included. The association between TOPS and mortality was investigated with a logistic regression model. Receiver-operating characteristics (ROC) curve was derived for TOPS; area under the ROC curve, sensitivity and specificity were calculated.
Results: In-transport mortality was 2/198 (1.0%) and in-hospital mortality was 75/196 (38.3%). Median gestational age and birthweight were 38 weeks and 2600 g. Main causes of admission were asphyxia (29.3%), prematurity (25.3%) and sepsis (22.7%). Hypothermia and oxygen desaturation at admission were 75.8% and 32.3%. TOPS ≥ 1 was associated with increased mortality risk (odds ratio 7.06. 95% confidence interval 1.90 to 45.82), with 0.97 sensitivity and 0.26 specificity.
Conclusions: The high mortality rate calls for interventions and quality initiative studies to improve the transfer process and the conditions at admission. TOPS can be used to identify neonates at risk of mortality and concentrate efforts of health care providers. Interventions preventing hypothermia and oxygen desaturation should be implemented in pre-transport stabilization and care during transport.
Project TOPS: Team-Based Oversight of Patient Satisfaction Through Real-Time Interdisciplinary Feedback
Background: Despite the financial incentives to improve patient experience, measured through the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey, few interventions have led to sustained improvement.
Methods: A real-time survey (RTS) designed to capture multiple domains was conducted on medical inpatients in a tertiary care center from July 2017 to June 2018. Answers were reviewed by a multidisciplinary team, and interventions to improve experience were completed.
Results: A total of 235 RTSs resulted in 94 (40.0%) interventions. HCAHPS were compared 12 months pre-and postintervention, with an increase in the percentage of "always" for the responsiveness domain, 38.9% vs. 59.7%, p = 0.005. Several other domains showed an increase that did not reach statistical significance.
Conclusion: Conducting RTSs may allow for a better understanding of patient experience and active service recovery.
