Outcomes and problems in pediatric pulmonary rehabilitation

High Rate of Medical Emergency Team Activation in Children with Tracheostomy

Pediatric in-patients with tracheostomy (PIT) are at high risk for clinical deterioration. Medical emergency teams (MET) have been developed to identify high-risk patients. This study compared MET activation rates between PITs and the general ward population. This was a retrospective cohort study conducted at a tertiary pediatric hospital. The primary outcome (MET activation) was obtained from a database. Between 2008 and 2014, the MET activation rate was significantly higher in the PIT group than the general ward population (14 vs. 2.9 per 100 admissions, p  < 0.001). PITs are at significantly higher risk for MET activation. Strategies should be developed to reduce their risk on the wards.

Weaning children from mechanical ventilation in a post-acute care setting

As medical and technological advances have made it possible to prolong the life of children with chronic respiratory failure, children are being referred to post-acute inpatient rehabilitation programmes. In these settings, children can be weaned from their ventilators and receive medical and rehabilitative care in a developmentally supportive environment at a lower financial cost than in an intensive care unit. There is strong evidence that weaning children from mechanical ventilation has beneficial effects on their functionality, ease of care and quality of life. There is, however, little scientific evidence describing how often successful weaning is achieved or the most effective methods. The purpose of this article is to present a consensus report detailing a structured approach to weaning children from mechanical ventilation in a post-acute care setting. This study proposes a Weaning Severity Index and a Weaning Algorithm for use in the assessment and implementation of the weaning process in post-acute rehabilitation. Future clinical studies are needed to validate the suggested approach to ventilator weaning and to determine whether or not the weaning algorithm results in beneficial patient outcomes.

Development and evaluation of a minimum data set for children with airway support for transfers between acute and post-acute care

OBJECTIVE

To generate consensus on the reasons why children with airway support transfer between acute and post-acute care; develop a minimum data set to transmit between care settings; and examine transfer reports to determine the frequency of data set content.

STUDY DESIGN

Two consensus development meetings were conducted of acute and post-acute care professionals to identify reasons for transfer and develop the minimum data set. A content analysis was used to generate the frequency of inclusion of minimum data set elements in the narrative reports of 15 acute to post-acute and 15 post-acute to acute transfer summaries. The observed frequencies were compared with the expected frequencies (95%), as were frequencies between the two groups.

RESULTS

Advanced diagnostic assessment and unexpected changes in medical, surgical and mental health conditions were the primary reasons for transfer from post-acute to acute care. For transfers in both directions, 20 of the 34 data elements were present in <75% of the cases and were statistically different than the pre-set 95% standard. No statistical difference in the occurrence of data elements between transfer directions existed.

CONCLUSION

A minimum data set has the potential to reduce redundancy, improve safety and optimize care co-ordination between facilities for children with airway support.

Pediatric tracheostomies: a recent experience from one academic center

OBJECTIVES

To describe the indications, surgical timing, length of stay, hospital charges, and discharge disposition of pediatric tracheostomy patients.

DESIGN

Retrospective case series.

SETTING

Large urban academic pediatric hospital.

PATIENTS

Seventy children and adolescents undergoing tracheostomy placement over a 24-month period.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Hospital database records were used to determine demographics and readmission rates, tabulate charges, and confirm deaths. Indications for tracheostomies included airway obstruction, inadequate airway protection, chronic lung disease, neuromuscular weakness, and central hypoventilation. Surgical timing of the tracheostomy was grouped into three categories: prolonged mechanical ventilation, elective, or emergent. The overall median hospital stay was 46 days (range 14-254) with a median hospital charge of $136,718 (range $36,237-$913,934). The prolonged mechanical ventilation group underwent a tracheostomy after a median of 26 days (mean 37.5 days) on the ventilator. Eighty-one percent of children were discharged home; 63% of children were readmitted within 6 months, with 11% requiring four or more admissions. The six-month mortality rate was 13%; no deaths were related to the tracheostomy.

CONCLUSIONS

Children with tracheostomies are a heterogeneous population. Children who require tracheostomy for long-term mechanical ventilation have longer hospital stays than children who receive a tracheotomy on an elective or emergent basis. Hospital readmissions should be anticipated in this complex group of patients.

Outcomes of post-acute hospital episodes for young children requiring airway support

In this descriptive study, we examined changes in invasive and non-invasive airway support; studied the rates of home discharge vs. long-term care or acute hospitalization; and examined the relationship between the level of airway support and discharge to home for 92 children (<3 years of age) with 104 admission-discharge episodes to a consortium of pediatric rehabilitation hospitals over a one-year period. We found a significant reduction (p < 0.001) in the level of airway support between admission and discharge. In 21 of 47 (45%) episodes, children weaned from mechanical ventilation to a less restrictive type of support. Sixty percent of the children had final discharges to home. There was a significant, though fair correlation (Spearman Rho = -0.344, p = 0.001) between home discharge and level of airway support. These outcomes data provide a multi-site baseline for understanding expected changes in airway support and home discharge rates of young children who are admitted to a post-acute inpatient program.

Ventilator weaning outcomes in chronic respiratory failure in children

The purpose of this study was to describe mechanical ventilation weaning outcomes for children with chronic respiratory failure discharged from one of six post-acute rehabilitation facilities. Demographic, clinical and outcome data were collected from the medical record. Forty-four children were included in this prospective series; 20 (45%) were weaned off the ventilator at discharge. Children required significantly lower levels of ventilatory support at discharge than admission. Hourly use on the ventilator decreased from admission to discharge for the full cohort and for the subgroup who required a ventilator at discharge. Seventy-five percent of the children discharged with a ventilator had a portable unit. We conclude that nearly half of the children using mechanical ventilation achieve weaning during a postacute rehabilitation admission, whereas others have positive outcomes in severity, hours off the ventilator or portability of equipment.

Oxygen and ventilator weaning during inpatient pediatric pulmonary rehabilitation

Rates of oxygen and ventilator weaning, and factors related to successful weaning in inpatient pediatric pulmonary programs for infants and young children, have not been frequently reported in the literature. A retrospective review was conducted of 34 infants and toddlers with either a diagnostic condition of prematurity (PM) or congenital anomalies/neuromuscular disease (CA/NM) discharged from an inpatient pulmonary program. These cases represent 67 hospital admission-discharge episodes over a 6-year period. The rate of successful oxygen weaning (decrease to 0 hr per day) and ventilator weaning (decrease to <12 hr per day) and predictive factors related to successful ventilator weaning per admission-discharge episode were examined. Successful oxygen weaning was achieved during 24% and successful ventilator weaning was achieved during 30% of the admission-discharge episodes. No significant relationships were found between the selected demographic and clinical factors and oxygen weaning. Using a logistic regression model, the major variable associated with successful ventilator weaning per admission-discharge episode was diagnostic condition. Age at admission and the presence of comorbidities added slightly to the prediction model. The overall model yielded 86% accuracy for predicting a decrease in ventilator hours. However, projecting in which episodes children will not be weaned (negative predictive value = 88.9%) was more accurate than projecting in which episodes children will be weaned (positive predictive value = 73.3%). Although the program achieved a relatively low rate of successful ventilator weaning, children with a diagnostic condition of prematurity were more likely to be successfully weaned during inpatient pulmonary rehabilitation.

Clinical findings and resource use of infants and toddlers dependent on oxygen and ventilators

Medical records were reviewed to describe characteristics, report clinical and resource measures, and determine if differences exist between the diagnostic groups of prematurity and multiple congenital anomalies/neurologic conditions for initial admissions of 37 infants and toddlers to an inpatient pulmonary rehabilitation program. More than 75% of the children had a tracheostomy at admission and discharge. Forty-six percent of the sample was admitted requiring only oxygen, whereas 51% were discharged requiring only oxygen and not mechanical ventilation. Thirty percent of the children weaned to a less invasive mode of ventilation while just under half of the children were discharged home. Between-group comparisons indicated statistically significant differences for nutritional support at discharge (p < or = 0.05) and discharge disposition (p = 0.04). Complete weaning of oxygen or ventilator support during an initial inpatient pulmonary rehabilitation admission occurred less frequently than weaning to a less invasive mode of ventilation. This is an important consideration for referring children to rehabilitation programs, for clinical program improvement activities, and for setting realistic expectations for referral sources, patients and families, clinical staff, and payers. Further study is recommended using clinical data in program planning, in program improvements, and for setting outcome expectations for infants and toddlers dependent on pulmonary technology.
