Re-admissions to inpatient paediatric pulmonary rehabilitation

Detecting Ventilator-Induced Diaphragmatic Dysfunction Using Point-of-Care Ultrasound in Children With Long-term Mechanical Ventilation

Long-term mechanical ventilation (MV) is defined as the use of MV for more than 6 hours per day for at least 3 weeks. Children requiring long-term MV include those with neuromuscular disease, central dysregulation, or lung dysfunction. Such children with medical complexity may be at risk for ventilator-induced diaphragmatic dysfunction. Ventilator-induced diaphragmatic dysfunction has been described in adult patients requiring acute MV with ultrasound (US). At this time, diaphragmatic US has not been evaluated in the pediatric post-acute care setting or incorporated into weaning strategies. We present 24 cases of children requiring long-term MV who underwent diaphragmatic US examinations to evaluate for ventilator-induced diaphragmatic dysfunction.

Readmission drivers for children with medical complexity: Home nursing shortages cause health crises

OBJECTIVE

Children with medical technology dependence (MTD) are frequently readmitted to the hospital. However, due to their medical fragility, it is often difficult to untangle the root causes for readmissions to identify the most effective preventive approaches. We sought to explore environmental and family factors driving hospital readmissions for children with MTD.

DESIGN

Semi-structured, in-person interviews were conducted with state-wide care coordinators for children with MTD in Illinois with at least 1 year of experience. Interview topics related to children with MTD transitioning from hospital-to-home, essential supports for living in the community, and factors which influenced and prevented hospital readmission. The interview guide served as an initial codebook which was iteratively modified as themes emerged.

RESULTS

Fifteen care coordinators with on average 6.6 years of experience were interviewed. They described that lack of home nursing was one of the primary drivers of readmissions due to parental exhaustion and lack of medical expertize in the home. Unavoidable medical admissions, a lack of a plan for emergencies, and home environmental factors also contributed to readmissions.

CONCLUSION

Hospital readmission is an expected occurrence for children with MTD, yet still may be substantially reduced through consistent, quality home health nursing to bolster family capacity and allow for respite from constant caregiving. Improved incentives for the home health workforce to increase manpower would be ultimately offset by reduced hospitalizations for children with MTD. Additionally, more research is needed to understand which home nursing structures and skills optimally support families in the reality of manpower scarcity.

Risk factors associated with paediatric unplanned hospital readmissions: a systematic review

OBJECTIVE

To synthesise evidence on risk factors associated with paediatric unplanned hospital readmissions (UHRs).

DESIGN

Systematic review.

DATA SOURCE

CINAHL, EMBASE (Ovid) and MEDLINE from 2000 to 2017.

ELIGIBILITY CRITERIA

Studies published in English with full-text access and focused on paediatric All-cause, Surgical procedure and General medical condition related UHRs were included.

DATA EXTRACTION AND SYNTHESIS

Characteristics of the included studies, examined variables and the statistically significant risk factors were extracted. Two reviewers independently assessed study quality based on six domains of potential bias. Pooling of extracted risk factors was not permitted due to heterogeneity of the included studies. Data were synthesised using content analysis and presented in narrative form.

RESULTS

Thirty-six significant risk factors were extracted from the 44 included studies and presented under three health condition groupings. For All-cause UHRs, ethnicity, comorbidity and type of health insurance were the most frequently cited factors. For Surgical procedure related UHRs, specific surgical procedures, comorbidity, length of stay (LOS), age, the American Society of Anaesthesiologists class, postoperative complications, duration of procedure, type of health insurance and illness severity were cited more frequently. The four most cited risk factors associated with General medical condition related UHRs were comorbidity, age, health service usage prior to the index admission and LOS.

CONCLUSIONS

This systematic review acknowledges the complexity of readmission risk prediction in paediatric populations. This review identified four risk factors across all three health condition groupings, namely comorbidity; public health insurance; longer LOS and patients<12 months or between 13-18 years. The identification of risk factors, however, depended on the variables examined by each of the included studies. Consideration should be taken into account when generalising reported risk factors to other institutions. This review highlights the need to develop a standardised set of measures to capture key hospital discharge variables that predict unplanned readmission among paediatric patients.

Outcomes of children with severe bronchopulmonary dysplasia who were ventilator dependent at home

OBJECTIVE

To describe the incidence and outcomes of children with chronic respiratory failure secondary to severe bronchopulmonary dysplasia (BPD) on chronic positive pressure ventilation (PPV) via tracheostomy at home.

METHODS

We retrospectively reviewed medical charts of patients with severe BPD who were PPV dependent at home and who were enrolled in a university-affiliated home ventilator program between 1984 and 2010. We excluded patients with other comorbidities that could contribute to the development of chronic respiratory failure. We reported the incidence of these children in Indiana and cumulative incidences of survival, liberation from PPV, and decannulation.

RESULTS

Over 27 years, 628 children were cared for in our home ventilator program. Of these, 102 patients met inclusion criteria: 83 (81.4%) were alive and 19 (18.6%) were deceased. Sixty-nine patients (67.6%) were liberated from PPV, and 97.1% of them were weaned before their fifth birthday, with a median age at liberation of 24 months (interquartile range, 19-33). Similarly, 60 patients (58.8%) were decannulated, of which 96.7% completed this process before their sixth birthday, with a median age at decannulation of 37.5 months (interquartile range, 31.5-45). The incidence of children with chronic respiratory failure secondary to BPD who were PPV-dependent at home in Indiana was 1.23 per 100 000 live births in 1984 and increased to 4.77 per 100 000 live births in 2010.

CONCLUSIONS

Although extreme prematurity associated with severe BPD necessitating PPV at home carries significant risks of morbidity and mortality, successful liberation from mechanical ventilation and decannulation are likely to occur.

Hospital readmissions for newly discharged pediatric home mechanical ventilation patients

BACKGROUND

Ventilator-dependent children have complex chronic conditions that put them at risk for acute illness and repeated hospitalizations.

OBJECTIVES

To determine the 12-month incidence of and risk factors for non-elective readmission in children with chronic respiratory failure (CRF) after initiation on home mechanical ventilation (HMV) via tracheostomy.

METHODS

A retrospective cohort study of 109 HMV patients initiated and followed at an university-affiliated children's hospital between 2003 and 2009. Patient characteristics are presented using descriptive statistics; generalized estimated equations are used to estimate adjusted odds ratios of select predictor variables for readmission.

RESULTS

The 12-month incidence of non-elective readmission was 40%. Close to half of these readmissions occurred within the first 3 months post-index discharge. Pneumonia and tracheitis were the most common reasons for readmission; 64% were pulmonary- or tracheostomy-related. Most demographic and clinical patient characteristics were not statistically associated with non-elective readmissions. Although, a change in the child's management within 7 days before discharge was associated readmissions shortly after index discharge.

CONCLUSION

Non-elective readmissions of newly initiated pediatric HMV patients were common and likely multifactorial. Many of these readmissions were airway-related, and some may have been potentially preventable.

Measuring physical function in children with airway support: a pilot study using computer adaptive testing

OBJECTIVE

To assess the responsiveness, examine the scoring range and determine the efficiency of a multidimensional computer adaptive testing version of the Pediatric Evaluation of Disability Inventory (PEDI-MCAT) for children admitted to inpatient pulmonary rehabilitation.

METHODS

The PEDI-MCAT was completed by clinician report for 30 infants and children. Mean self-care and mobility admission scores were compared with discharge scores for the total group and two diagnostic sub-groups (prematurity and congenital/neurological conditions). The scoring range of the mobility and self-care scales was examined to determine placement of the scores along the overall PEDI-MCAT scale. Efficiency was determined using an internal clock and average number of items required for score generation.

RESULTS

Mean changes for the total group and both sub-groups were significant for both self-care and mobility, except for the prematurity group's mobility scores. Effect sizes were small-to-moderate. Scores for both groups were at the low end of the scoring ranges. Average time to complete the PEDI-MCAT was 1.57 minutes. Average number of items administered was nine for self-care and 11 for mobility.

CONCLUSION

The PEDI-MCAT was responsive to change in physical function, although only low-ability items were needed. The PEDI-MCAT can potentially minimize clinician burden in inpatient settings.

Predictors of clinical outcomes and hospital resource use of children after tracheotomy

OBJECTIVES

The objectives are to describe health outcomes and hospital resource use of children after tracheotomy and identify patient characteristics that correlate with outcomes and hospital resource use.

PATIENTS AND METHODS

A retrospective analysis of 917 children aged 0 to 18 years undergoing tracheotomy from 36 children's hospitals in 2002 with follow-up through 2007. Children were identified from ICD-9-CM tracheotomy procedure codes. Comorbid conditions (neurologic impairment [NI], chronic lung disease, upper airway anomaly, prematurity, and trauma) were identified with ICD-9-CM diagnostic codes. Patient characteristics were compared with in-hospital mortality, decannulation, and hospital resource use by using generalized estimating equations.

RESULTS

Forty-eight percent of children were <or=6 months old at tracheotomy placement. Chronic lung disease (56%), NI (48%), and upper airway anomaly (47%) were the most common underlying comorbid conditions. During hospitalization for tracheotomy placement, children with an upper airway anomaly experienced less mortality (3.3% vs 11.7%; P < .001) than children without an upper airway anomaly. Five years after tracheotomy, children with NI experienced greater mortality (8.8% vs 3.5%; P <or= .01), less decannulation (5.0% vs 11.0%; P <or= .01), and more total number of days in the hospital (mean [SE]: 39.5 [4.0] vs 25.6 [2.6] days; P <or= .01) than children without NI. These findings remained significant (P < .01) in multivariate analysis after controlling for other significant cofactors.

CONCLUSIONS

Children with upper airway anomaly experienced less mortality, and children with NI experienced higher mortality rates and greater hospital resource use after tracheotomy. Additional research is needed to explore additional factors that may influence health outcomes in children with tracheotomy.

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.

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.
