Effectiveness of paediatric asthma clinical pathways: a narrative systematic review

Racial differences in length of stay and readmission for asthma in the all of us research program

BACKGROUND

This study addresses the limited research on racial disparities in asthma hospitalization outcomes, specifically length of stay (LOS) and readmission, across the U.S.

METHODS

We analyzed in-patient and emergency department visits from the All of Us Research Program, identifying various risk factors (demographic, comorbid, temporal, and place-based) associated with asthma LOS and 30-day readmission using Bayesian mixed-effects models.

RESULTS

Of 17,233 patients (48.0% White, 30.7% Black, 19.7% Hispanic/Latino, 1.3% Asian, and 0.3% Middle Eastern and North African) with 82,188 asthma visits, Black participants had 20% shorter LOS and 12% higher odds of readmission, compared to White participants in multivariate analyses. Public-insured patients had 14% longer LOS and 39% higher readmission odds than commercially insured patients. Weekend admissions resulted in a 12% shorter LOS but 10% higher readmission odds. Asthmatics with chronic diseases had a longer LOS (range: 6-39%) and higher readmission odds (range: 9-32%) except for those with allergic rhinitis, who had a 23% shorter LOS.

CONCLUSIONS

A comprehensive understanding of the factors influencing asthma hospitalization, in conjunction with diverse datasets and clinical-community partnerships, can help physicians and policymakers to systematically address racial disparities, healthcare utilization and equitable outcomes in asthma care.

Barriers and Facilitators of High-Efficiency Clinical Pathway Implementation in Community Hospitals

BACKGROUND

An intervention that involved simultaneously implementing clinical pathways for multiple conditions was tested at a tertiary children's hospital and it improved care quality. We are conducting a randomized trial to evaluate this multicondition pathway intervention in community hospitals. Our objectives in this qualitative study were to prospectively (1) identify implementation barriers and (2) map barriers to facilitators using an established implementation science framework.

METHODS

We recruited participants via site leaders from hospitals enrolled in the trial. We designed an interview guide using the Consolidated Framework for Implementation Research and conducted individual interviews. Analysis was done using constant comparative methods. Anticipated barriers were mapped to facilitators using the Capability, Opportunity, Motivation, Behavior Framework.

RESULTS

Participants from 12 hospitals across the United States were interviewed (n = 21). Major themes regarding the multicondition pathway intervention included clinician perceptions, potential benefits, anticipated barriers/challenges, potential facilitators, and necessary resources. We mapped barriers to additional facilitators using the Capability, Opportunity, Motivation, Behavior framework. To address limited time/bandwidth of clinicians, we will provide Maintenance of Certification credits. To address new staff and trainee turnover, we will provide easily accessible educational videos/resources. To address difficulties in changing practice across other hospital units, we will encourage emergency department engagement. To address parental concerns with deimplementation, we will provide guidance on parent counseling.

CONCLUSIONS

We identified several potential barriers and facilitators for implementation of a multicondition clinical pathway intervention in community hospitals. We also illustrate a prospective process for identifying implementation facilitators.

Discharge criteria for inpatient paediatric asthma: a narrative systematic review

INTRODUCTION

Criteria-led discharges (CLDs) and inpatient care pathways (ICPs) aim to standardise care and improve efficiency by allowing patients to be discharged on fulfilment of discharge criteria. This narrative systematic review aims to summarise the evidence for use of CLDs and discharge criteria in ICPs for paediatric inpatients with asthma, and summarise the evidence for each discharge criterion used.

METHODS

Database search using keywords was performed using Medline, Embase and PubMed for studies published until 9 June 2022. Inclusion criteria included: paediatric patients <18 years old, admitted to hospital with asthma or wheeze and use of CLD, nurse-led discharge or ICP. Reviewers screened studies, extracted data and assessed study quality using the Quality Assessment with Diverse Studies tool. Results were tabulated. Meta-analysis was not performed due to heterogeneity of study designs and outcomes.

RESULTS

Database search identified 2478 studies. 17 studies met the inclusion criteria. Common discharge criteria include bronchodilator frequency, oxygen saturation and respiratory assessment. Discharge criteria definitions varied between studies. Most definitions were associated with improvements in length of stay (LOS) without increasing re-presentation or readmission.

CONCLUSION

CLDs and ICPs in the care of paediatric inpatients with asthma are associated with improvements in LOS without increasing re-presentations or readmissions. Discharge criteria lack consensus and evidence base. Common criteria include bronchodilator frequency, oxygen saturations and respiratory assessment. This study was limited by a paucity of high-quality studies and exclusion of studies not published in English. Further research is necessary to identify optimal definitions for each discharge criterion.

Harmonizing allergy care-integrated care pathways and multidisciplinary approaches

There is a wide time gap between the publication of evidence and the application of new knowledge into routine clinical practice. The consequence is sub-optimal outcomes, particularly concerning for long-term relapsing/remitting conditions such as allergic diseases. In response, there has been a proliferation of published guidelines which systematically review evidence for the gold-standard management of most allergic disorders. However, this has not necessarily been followed by improved outcomes, partly due to a lack of coordination across the patient pathway. This has become known as the "second translational gap". A proposed solution is the development and implementation of integrated care pathways (ICPs) to optimize patient outcomes, with the notion that evidence-based medicine requires evidence-based implementation. ICP implementation is shown to improve short-term outcomes for acute conditions and routine surgery, including reduced length of hospital stay, improved documentation and improved patient safety. However, this improvement is not reflected in patient experience or patient-centered functional outcomes. The implementation of life-long, cost-effective interventions within comprehensive pathways requires a deep appreciation for complexity within allergy care.

We promote an evidence-based methodology for the implementation of ICPs for allergic disorders in which all stakeholders in allergy care are positioned equally and encouraged to contribute, particularly patients and their caregivers. This evidence-based process commences with scoping the unmet needs, followed by stakeholder mapping. All stakeholders are invited to meetings to develop a common vision and mission through the generation of action/effect diagrams which helps build concordance across the agencies. Dividing the interventions into achievable steps and reviewing with plan/do/study/act cycles will gradually modify the pathway to achieve the best outcomes. While the management guidelines provide the core knowledge, the key component of implementation involves education, training, and support of all healthcare professionals (HCPs), patients and their caregivers.

The pathways should define the level of competence required for each clinical task. It may be useful to leave the setting of care delivery or the specific HCP involved undefined to account for variable patterns of health service delivery as well as local socioeconomic, ethnic, environmental, and political imperatives. In all cases, where competence is exceeded, it is necessary to refer to the next stage in the pathway. The success and sustainability of ICPs would ideally be judged by patient experience, health outcomes, and health economics. We provide examples of successful programs, most notably from Finland, but recommend that further research is required in diverse settings to optimize outcomes worldwide.

Paediatrics: how to manage acute asthma exacerbations

Background

Asthma is the most common chronic disease of childhood and a major source of childhood health burden worldwide. These burdens are particularly marked when children experience characteristic ‘symptom flare-ups’ or acute asthma exacerbations (AAEs). AAE are associated with significant health and economic impacts, including acute Emergency Department visits, occasional hospitalizations, and rarely, death. To treat children with AAE, several medications have been studied and used.

Methods

We conducted a narrative review of the literature with the primary objective of understanding the evidence of their efficacy. We present this efficacy evidence in the context of a general stepwise management pathway for paediatric AAEs. This framework is developed from the combined recommendations of eight established (inter)national paediatric guidelines.

Discussion

Management of paediatric AAE centres around four major care goals: (1) immediate and objective assessment of AAE severity; (2) prompt and effective medical interventions to decrease respiratory distress and improve oxygenation; (3) appropriate disposition of patient; and (4) safe discharge plans. Several medications are currently recommended with varying efficacies, including heliox, systemic corticosteroids, first-line bronchodilators (salbutamol/albuterol), adjunctive bronchodilators (ipratropium bromide, magnesium sulfate) and second-line bronchodilators (aminophylline, i.v. salbutamol, i.v. terbutaline, epinephrine, ketamine). Care of children with AAE is further enhanced using clinical severity scoring, pathway-driven care and after-event discharge planning.

Conclusions

AAEs in children are primarily managed by medications supported by a growing body of literature. Continued efforts to study the efficacy of second-line bronchodilators, integrate AAE management with long-term asthma control and provide fair/equitable care are required.

Impact of obstructive sleep apnea on assisted ventilation in children with asthma exacerbation

OBJECTIVE

To determine the impact of obstructive sleep apnea (OSA) on asthma exacerbation severity in children hospitalized for asthma exacerbation.

HYPOTHESIS

OSA is associated with greater use of invasive mechanical ventilation (IMV) and noninvasive mechanical ventilation (NIMV) in children hospitalized for asthma exacerbation.

STUDY DESIGN

A retrospective cohort study.

PATIENT-SUBJECT SELECTION

Hospitalization records of children aged 2-18 years admitted for acute asthma exacerbation were obtained for 2000, 2003, 2006, 2009, and 2012 from the Kids' Inpatient Database.

METHODOLOGY

The primary exposure was OSA, the primary outcome was IMV, and secondary outcomes were NIMV, length of hospital stay (LOS), and inflation-adjusted cost of hospitalization. Multivariable logistic regression, negative binomial, and linear regression were conducted to ascertain the impact of OSA on primary and secondary outcomes. Exploratory analyses investigated the impact of obesity on primary and secondary outcomes.

RESULTS

Among 564,467 hospitalizations for acute asthma exacerbation, 4209 (0.75%) had OSA. Multivariable regression indicated that OSA was associated with IMV (adjusted odds ratio [OR], 5.33 [95% confidence interval, CI: 4.35-6.54], p < .0001), NIMV (adjusted OR, 8.30 [95% CI: 6.56-10.51], p < .0001), longer LOS (adjusted incidence rate ratio, 1.34 [95% CI 1.28-1.43], p < .0001), and greater inflation-adjusted cost of hospitalization (adjusted β, 0.38 [95% CI: 0.33-0.43], p < .0001). Obesity was also significantly associated IMV, NIMV, longer LOS, and greater inflation-adjusted cost of hospitalization. There was no interaction between OSA and obesity.

CONCLUSION

OSA is an independent risk factor for IMV, NIMV, longer LOS, and elevated inflation-adjusted costs of hospitalization in children hospitalized for asthma exacerbation.

Sustainability of paediatric asthma care quality in community hospitals after ending a national quality improvement collaborative

BACKGROUND

Community hospitals, which care for most hospitalised children in the USA, may be vulnerable to declines in paediatric care quality when quality improvement (QI) initiatives end. We aimed to evaluate changes in care quality in community hospitals after the end of the Pathways for Improving Paediatric Asthma Care (PIPA) national QI collaborative.

METHODS

We conducted a longitudinal cohort study during and after PIPA. PIPA included 45 community hospitals, of which 34 completed the 12-month collaborative and were invited for extended sustainability monitoring (total of 21-24 months from collaborative start). PIPA provided paediatric asthma pathways, educational materials/seminars, QI mentorship, monthly data reports, a mobile application and peer-to-peer learning opportunities. Access to pathways, educational materials and the mobile application remained during sustainability monitoring. Charts were reviewed for children aged 2-17 years old hospitalised with a primary diagnosis of asthma (maximum 20 monthly per hospital). Outcomes included measures of guideline adherence (early bronchodilator administration via metered-dose inhaler (MDI), secondhand smoke screening and referral to smoking cessation resources) and length of stay (LOS). We evaluated outcomes using multilevel regression models adjusted for patient mix, using an interrupted time-series approach.

RESULTS

We analysed 2159 hospitalisations from 23 hospitals (68% of eligible). Participating hospitals were structurally similar to those that dropped out but had more improvement in guideline adherence during the collaborative (29% vs 15%, p=0.02). The end of the collaborative was associated with a significant initial decrease in early MDI administration (81%-68%) (adjusted OR (aOR) 0.26 (95% CI 0.15 to 0.42)) and decreased rate of referral to smoking cessation resources (2.2% per month increase to 0.3% per month decrease) (aOR 0.86 (95% CI 0.75 to 0.98)) but no significant changes in LOS or secondhand smoke screening.

CONCLUSIONS

The end of a paediatric asthma QI collaborative was associated with concerning declines in guideline adherence in community hospitals.

Effectiveness of Pediatric Asthma Pathways in Community Hospitals: A Multisite Quality Improvement Study

Pathways guide clinicians through evidence-based care of specific conditions. Pathways have been demonstrated to improve pediatric asthma care, but mainly in studies at tertiary children's hospitals. Our global aim was to enhance the quality of asthma care across multiple measures by implementing pathways in community hospitals.

Methods

This quality improvement study included children ages 2-17 years with a primary diagnosis of asthma. Data were collected before and after pathway implementation (total 28 mo). Pathway implementation involved local champions, educational meetings, audit/feedback, and electronic health record integration. Emergency department (ED) measures included severity assessment at triage, timely systemic corticosteroid administration (within 60 mins), chest radiograph (CXR) utilization, hospital admission, and length of stay (LOS). Inpatient measures included screening for secondhand tobacco and referral to cessation resources, early administration of bronchodilator via metered-dose inhaler, antibiotic prescription, LOS, and 7-day readmission/ED revisit. Analyses were done using statistical process control.

Results

We analyzed 881 ED visits and 138 hospitalizations from 2 community hospitals. Pathways were associated with increases in the proportion of children with timely systemic corticosteroid administration (Site 1: 32%-57%, Site 2: 62%-75%) and screening for secondhand tobacco (Site 1: 82%-100%, Site 2: 54%-89%); and decreases in CXR utilization (Site 1: 44%-29%), ED LOS (Site 1: 230-197 mins), and antibiotic prescription (Site 2: 23%-3%). There were no significant changes in other outcomes.

Conclusions

Pathways improved pediatric asthma care quality in the ED and inpatient settings of community hospitals.

Evaluation of an Innovative Model of Care for a Limited-Stay Pediatric Unit

Information about pediatric observation and limited-stay unit design and function is lacking in the literature. A quality improvement approach was used to create new care processes on an inpatient unit within a large children's hospital. Outcomes included the use of advanced practice nurse patient care management, creation of 30 clinical pathways to model care, and consistent and faster transfer from emergency department to inpatient unit, resulting in high-level parent and patient satisfaction and decreased nursing turnover.

Pathways for Improving Inpatient Pediatric Asthma Care (PIPA): A Multicenter, National Study

BACKGROUND AND OBJECTIVES

Pathways guide clinicians through evidence-based care of specific conditions. Pathways have been demonstrated to improve inpatient asthma care but mainly in studies at large, tertiary children's hospitals. It remains unclear if these effects are generalizable across diverse hospital settings. Our objective was to improve inpatient asthma care by implementing pathways in a diverse, national sample of hospitals.

METHODS

We used a learning collaborative model. Pathway implementation strategies included local champions, external facilitators and/or mentors, educational seminars, quality improvement methods, and audit and feedback. Outcomes included length of stay (LOS) (primary), early administration of metered-dose inhalers, screening for secondhand tobacco exposure and referral to cessation resources, and 7-day hospital readmissions or emergency revisits (balancing). Hospitals reviewed a sample of up to 20 charts per month of children ages 2 to 17 years who were admitted with a primary diagnosis of asthma (12 months before and 15 months after implementation). Analyses were done by using multilevel regression models with an interrupted time series approach, adjusting for patient characteristics.

RESULTS

Eighty-five hospitals enrolled (40 children's and 45 community); 68 (80%) completed the study (n = 12 013 admissions). Pathways were associated with increases in early administration of metered-dose inhalers (odds ratio: 1.18; 95% confidence interval [CI]: 1.14-1.22) and referral to smoking cessation resources (odds ratio: 1.93; 95% CI: 1.27-2.91) but no statistically significant changes in other outcomes, including LOS (rate ratio: 1.00; 95% CI: 0.96-1.06). Most hospitals (65%) improved in at least 1 outcome.

CONCLUSIONS

Pathways did not significantly impact LOS but did improve quality of asthma care for children in a diverse, national group of hospitals.

Standardized Protocol Is Associated With a Decrease in Continuous Albuterol Use and Length of Stay in Critical Status Asthmaticus

OBJECTIVES

The primary aim of this study was to reduce duration of continuous albuterol and hospital length of stay in critically ill children with severe status asthmaticus.

DESIGN

Observational prospective study from September 2012 to May 2016.

SETTING

Medicine ICU and intermediate care unit.

PATIENTS

Children greater than 2 years old with admission diagnosis of status asthmaticus admitted on continuous albuterol and managed via a standardized protocol.

INTERVENTIONS

The protocol was an iterative algorithm for escalation and weaning of therapy. The algorithm underwent three revisions. Iteration 1 concentrated on reducing duration on continuous albuterol; iteration 2 concentrated on reducing hospital length of stay; and iteration 3 concentrated on reducing helium-oxygen delivered continuous albuterol. Balancing measures included adverse events and readmissions.

MEASUREMENTS AND RESULTS

Three-hundred eighty-five patients were treated as follows: 123, 138, and 124 in iterations 1, 2, and 3, respectively. Baseline data was gathered from an additional 150 patients prior to protocol implementation. There was no difference in median age (6 vs 8 vs 7 vs 7 yr; p = 0.130), asthma severity score (9 vs 9 vs 9 vs 9; p = 0.073), or female gender (42% vs 41% vs 43% vs 48%; p = 0.757). Using statistical process control charts, the mean duration on continuous albuterol decreased from 24.9 to 17.5 hours and the mean hospital length of stay decreased from 76 to 49 hours. There was no difference in adverse events (0% vs 1% vs 4% vs 0%; p = 0.054) nor in readmissions (0% vs 0% vs 1% vs 2%; p = 0.254).

CONCLUSIONS

Implementation of a quality improvement protocol in critically ill patients with status asthmaticus was associated with a decrease in continuous albuterol duration and hospital length of stay.

Implementing pediatric inpatient asthma pathways

OBJECTIVE

Pathways are succinct, operational versions of evidence-based guidelines. Studies have demonstrated pathways improve quality of care for children hospitalized with asthma, but we have limited information on other key factors to guide hospital leaders and clinicians in pathway implementation efforts. Our objective was to evaluate the adoption, implementation, and reach of inpatient pediatric asthma pathways.

METHODS

This was a mixed-methods study of hospitals participating in a national collaborative to implement pathways. Data sources included electronic surveys of implementation leaders and staff, field observations, and chart review of children ages 2-17 years admitted with a primary diagnosis of asthma. Outcomes included adoption by hospitals, pathway implementation factors, and reach of pathways to children hospitalized with asthma. Quantitative data were analyzed using descriptive statistics and multivariable regression. Qualitative data were analyzed using thematic content analysis.

RESULTS

Eighty-five hospitals enrolled; 68 (80%) adopted/completed the collaborative. These 68 hospitals implemented pathways with overall high fidelity, implementing a median of 5 of 5 core pathway components (Interquartile Range [IQR] 4-5) in a median of 5 months (IQR 3-9). Implementation teams reported a median time cost of 78 h (IQR: 40-120) for implementation. Implementation leaders reported the values of pathway implementation included improvements in care, enhanced interdisciplinary collaboration, and access to educational resources. Leaders reported barriers in modifying electronic health records (EHRs), and only 63% of children had electronic pathway orders placed.

CONCLUSIONS

Hospitals implemented pathways with high fidelity. Barriers in modifying EHRs may have limited the reach of pathways to children hospitalized with asthma.

Direct medical costs of pediatric asthma exacerbations requiring hospital attendance in a middle-income country

INTRODUCTION AND OBJECTIVES

With the aim of making informed decisions on resource allocation, there is a critical need for studies that provide accurate information on hospital costs for treating pediatric asthma exacerbations, mainly in middle-income countries (MICs). The aim of the present study was to evaluate the direct medical costs associated with pediatric asthma exacerbations requiring hospital attendance in Bogota, Colombia.

PATIENTS AND METHODS

We reviewed the available electronic medical records (EMRs) for all pediatric patients who were admitted to the Fundacion Hospital de La Misericordia with a discharge principal diagnosis pediatric asthma exacerbation over a 24-month period from January 2016 to December 2017. Direct medical costs of pediatric asthma exacerbations were retrospectively collected by dividing the patients into four groups: those admitted to the emergency department (ED) only; those admitted to the pediatric ward (PW); those admitted to the pediatric intermediate care unit (PIMC); and those admitted to the pediatric intensive care unit (PICU).

RESULTS

A total of 252 patients with a median (IQR) age of 5.0 (3.0-7.0) years were analyzed, of whom 142 (56.3%) were males. Overall, the median (IQR) cost of patients treated in the ED, PW, PIMC, and PICU was US$38.8 (21.1-64.1) vs. US$260.5 (113.7-567.4) vs. 1212.4 (717.6-1609.6) vs. 2501.8 (1771.6-3405.0), respectively: this difference was statistically significant (p<0.001).

CONCLUSIONS

The present study helps to further our understanding of the economic burden of pediatric asthma exacerbations requiring hospital attendance among pediatric patients in a MIC.

Implementing Pediatric Asthma Pathways in Community Hospitals: A National Qualitative Study

BACKGROUND

Pathways can improve the quality of care and outcomes for children with asthma; however, we know little about how to successfully implement pathways across diverse hospital settings. Prior studies of pathways have focused on determining clinical effectiveness and the majority were conducted in children's hospitals. These approaches have left crucial gaps in our understanding of how to successfully implement pathways in community hospitals, where most of the children with asthma are treated nationally.

OBJECTIVE

The aim of this study was to identify the key determinants of successful pediatric asthma pathway implementation in community hospitals.

METHODS

We conducted a qualitative study of healthcare providers that served as project leaders in a national collaborative to improve pediatric asthma care. Data were collected by recording semi-structured discussions between project leaders and external facilitators (EF) from December 2017 to April 2018. Using inductive thematic analysis, we identified the themes that describe the key determinants of pathway implementation.

RESULTS

Project leaders (n = 32) from 18 hospitals participated in this study. The key determinants of pathway implementation in community hospitals included (1) building an implementation infrastructure (eg, forming a team of local champions, modifying clinical workflows, delivering education/skills training), (2) engaging and motivating providers (eg, obtaining project buy-in, facilitating multidisciplinary collaboration, handling conflict), (3) addressing organizational and resource limitations (eg, support for electronic medical record integration), and (4) devising implementation solutions with EFs (eg, potential workflow modifications).

CONCLUSIONS

Our identification of the key determinants of pathway implementation may help guide pediatric quality improvement efforts in community hospitals. EFs may play an important role in successfully implementing pathways in community settings.

White Coats at the Coalface: The Standardizing Work of Professionals at the Frontline

This study advances theory on professionals by introducing a novel ‘coalface perspective’ to study frontline professionals’ standardizing work. Our multimethod quantitative and qualitative approach explores when, why and how medical professionals in German university hospitals actively maintain care pathway enactment – a technique to standardize day-to-day medical work – in their everyday patient treatment. Professionals’ actively standardizing their work is an understudied yet highly relevant phenomenon that the established ‘autonomy perspective’ – which covers how professionals resist standardization – falls short of explaining. Introducing a coalface perspective overcomes this shortcoming by uncovering novel links between professionals’ day-to-day problem-driven motivations for standardizing work, the characteristics of everyday situations of frontline professional work and practices of standardizing work at the frontline. This study has implications for research on frontline professionals and coalface-perspective research in general.

Effects of Clinical Pathways for COPD on Patient, Professional, and Systems Outcomes: A Systematic Review

BACKGROUND

COPD has a substantial burden seen in both patient quality of life and health-care costs. One method of minimizing this burden is the implementation of clinical pathways (CPWs). CPWs bring the best available evidence to a range of health-care professionals by adapting guidelines to a local context and detailing essential steps in care.

METHODS

A systematic review was conducted to address the following question: What are the effects of CPWs for COPD on patient-, professional-, and systems-level outcomes? The review used methods outlined by the Cochrane Collaboration. We included all studies that met our operational definition for CPWs and focused on COPD. All studies were evaluated for risk of bias, and all data regarding patient, professional, and systems outcomes were extracted.

RESULTS

The search strategy identified 497 potentially relevant titles. Of these, 13 studies were included in the review. These studies reported a total of 398 outcomes, with sufficient data for meta-analysis of five outcomes: complications, length of stay, mortality, readmissions, and quality of life. Results showed statistically significant reductions in complications, readmissions, and length of stay but did not show changes in mortality or quality of life.

CONCLUSIONS

This systematic review reveals evidence to suggest that CPWs for COPD have the potential to reduce complications, readmissions, and length of stay without negatively influencing mortality or quality of life. However, quality of evidence was generally low. The authors therefore acknowledge that results should be interpreted with caution and note the need for additional research in this area.

Best practices in implementing inpatient pediatric asthma pathways: a qualitative study

Objective: Clinical pathways (operational versions of practice guidelines) can improve guideline adherence and quality of care for children hospitalized with asthma. However, there is limited guidance on how to implement pathways successfully. Our objective was to identify potential best practices in pathway implementation.Methods: In a previous observational study, we identified higher and lower performing children's hospitals based on hospital-level changes in asthma patient length of stay after implementation of a pathway. In this qualitative study, we conducted semi-structured interviews with a purposive sample of healthcare providers involved in pathway implementation at these hospitals. We used constant comparative methods to develop a conceptual model of potential best practices in implementation.Results: Healthcare providers (n = 24) from 6 higher performing and 2 lower performing hospitals were interviewed about pathway implementation. We identified several practices that addressed barriers and promoted successful pathway implementation: (1) utilizing quality improvement (QI) methodology and a data-driven approach helped overcome inertia of current practice; (2) getting teams to commit to shared goals around asthma care helped overcome disagreements in the implementation process; (3) integrating pathways into the electronic medical record decreased some burdens of implementation; (4) leveraging multidisciplinary teams by developing protocols for nurses and/or respiratory therapists to titrate medications reduced variability in provider practice; and (5) engaging hospital leaders with pathway implementation teams helped secure crucial resources.Conclusions: We identified several potential best practices to support pathway implementation. Hospitals implementing pathways should consider applying these strategies to better ensure success in improving quality of asthma care for children.

Reducing pediatric asthma hospital length of stay through evidence-based quality improvement and deployment of computerized provider order entry

Objective: Evaluate the impact of multi-component quality improvement for pediatric asthma care focusing on serial use of an evidence-based clinical pathway via paper order sets, pathway integration into computerized provider order entry (CPOE), use of a clinical respiratory score (CRS) and a discharge checklist. Methods: Outcomes were assessed over three intervention periods and 50 months on: time to beta-agonist and steroid first administration, frequency of readmissions and hospital length of stay. A general linear model estimated mean log(LOS) over time and between study periods. Time to discharge was transformed using the natural logarithm. Results: No improvements in time to first beta-agonist or steroid administration were observed. There was a reduction in 100-day readmissions (p = 0.008): decreasing from 7.4 to 2.1% after introduction of paper order sets and CRS (adjusted p = 0.04); to 3.9% after CPOE implementation (adjusted p = 0.53) and to 2.2% when a discharge checklist was added (adjusted p = 0.01). There was a statistically significant reduction in LOS between study periods (p = 0.015). The geometric mean LOS in hours during study periods 1-4 were: 34.8 (95% CI: 32.2, 37.6), 29.3 (95% CI: 27.5, 31.3), 29.0 (95% CI: 27.0, 31.3) and 23.1 (95% CI: 22.1, 24.2). Pair-wise comparisons between periods were statistically significant (adjusted p ≤ 0.003), except for Periods 2 and 3 (adjusted p = 0.83). Conclusions: Hospital length of stay and 100-day readmissions rate in a predominantly Hispanic, Medicaid patient population were reduced by utilization of an evidence-based best practices asthma management pathway and CRS within CPOE, combined with a checklist to expedite discharge.

Discharging Asthma Patients on 3-Hour β-Agonist Treatments: A Quality Improvement Project

OBJECTIVES

Asthma exacerbations are a leading cause of hospitalization among children. Despite the existence of hospital protocols and national guidelines, little guidance is available regarding appropriate short-acting β-agonist (SABA) frequency discharge criteria. Our aim was to reduce the median length of stay (LOS) for children hospitalized with asthma exacerbations by 4 hours by changing the discharge requirement SABA frequency.

METHODS

Multiple plan-do-study-act cycles based on findings in our key driver diagram were used to decrease LOS. Our primary intervention was reducing the SABA administration frequency discharge requirement from every 4 hours to every 3 hours. After a feasibility pilot, this change was implemented throughout the hospital. Our intervention bundle included updating our evidence-based guidelines, electronic health record order sets and note templates, house-wide education, and a new process for respiratory therapists to notify physicians of discharge readiness. Our primary metric was LOS, with 3-, 7-, and 14-day same-cause emergency department (ED) revisits and hospital readmissions as balancing metrics. Statistical process control charts and nonparametric testing were performed for data analysis.

RESULTS

Median hospital LOS was significantly lower in the postintervention period compared with the preintervention period (30.18 vs 36.14 hours respectively; P < .001). Statistical process control charts indicated special cause variation was achieved. No significant differences were observed in rates of ED revisits or hospital readmissions.

CONCLUSIONS

Reducing the discharge requirement of SABA frequency from every 4 hours to every 3 hours resulted in a reduction in LOS, with no increase in ED recidivism or hospital readmission rates.

The Impact of a Clinical Asthma Pathway on Resident Education

Clinical pathways for asthma management decrease hospital cost and length of stay; however little is known about the educational impact of pathways on residents. Pediatric residents at a children's hospital (N = 114) were invited to complete a 22-item computerized, anonymous survey 6 months before and 6 months after asthma pathway implementation. The survey assessed pathway use and residents (1) pathway knowledge, (2) attitudes and experiences with managing asthma, and (3) perceived educational benefits. Mean pathway knowledge score increased from the case before to the case after implementation [1.5 ± 1.0 versus 2.6 ± 1.3, p < 0.001], as did high preparedness to manage asthma [61% versus 91%, p < 0.001] and electronic order set use [28% versus 80%, p < 0.001]. The top three educational benefits of the pathway endorsed by residents were application of evidence-based medicine (57%), ability to assess exacerbations (52%), and skill at communicating respiratory status (47%). After implementation, residents' knowledge and preparedness to manage asthma improved as well as many endorsed educational benefits.

The '6W' multidimensional model of care trajectories for patients with chronic ambulatory care sensitive conditions and hospital readmissions

OBJECTIVES

To synthesize concepts and approaches related to the analysis of patterns or processes of care and patient's outcomes into a comprehensive model of care trajectories, focusing on hospital readmissions for patients with chronic ambulatory care sensitive conditions (ACSCs).

STUDY DESIGN

Narrative literature review.

METHODS

Published studies between January 2000 and November 2017, using the concepts of 'continuity', 'pathway', 'episode', and 'trajectory', and focused on readmissions and chronic ACSCs, were collected in electronic databases. Qualitative content analysis was performed with emphasis on key constituents to build a comprehensive model.

RESULTS

Specific common constituents are shared by the concepts reviewed: they focus on the patient, aim to measure and improve outcomes, follow specific periods of time and consider other factors related to care providers, care units, care settings, and treatments. Using these common denominators, the comprehensive '6W' multidimensional model of care trajectories was created. Considering patients' attributes and their chronic ACSCs illness course ('who' and 'why' dimensions), this model reflects their patterns of health care use across care providers ('which'), care units ('where'), and treatments ('what'), at specific periods of time ('when').

CONCLUSIONS

The '6W' model of care trajectories could provide valuable information on 'missed opportunities' to reduce readmission rates and improve quality of both ambulatory and inpatient care.

Implementation and Improvement of Pediatric Asthma Guideline Improves Hospital-Based Care

BACKGROUND

Standardized pediatric asthma care has been shown to improve measures in specific hospital areas, but to our knowledge, the implementation of an asthma clinical practice guideline (CPG) has not been demonstrated to be associated with improved hospital-wide outcomes. We sought to implement and refine a pediatric asthma CPG to improve outcomes and throughput for the emergency department (ED), inpatient care, and the ICU.

METHODS

An urban, quaternary-care children's hospital developed and implemented an evidence-based, pediatric asthma CPG to standardize care from ED arrival through discharge for all primary diagnosis asthma encounters for patients ≥2 years old without a complex chronic condition. Primary outcomes included ED and inpatient length of stay (LOS), percent ED encounters requiring admission, percent admissions requiring ICU care, and total charges. Balancing measures included the number of asthma discharges between all-cause 30-day readmissions after asthma discharges and asthma relapse within 72 hours. Statistical process control charts were used to monitor and analyze outcomes.

RESULTS

Analyses included 3650 and 3467 encounters 2 years pre- and postimplementation, respectively. Postimplementation, reductions were seen in ED LOS for treat-and-release patients (3.9 hours vs 3.3 hours), hospital LOS (1.5 days vs 1.3 days), ED encounters requiring admission (23.5% vs 18.8%), admissions requiring ICU (23.0% vs 13.2%), and total charges ($4457 vs $3651). Guideline implementation was not associated with changes in balancing measures.

CONCLUSIONS

The hospital-wide standardization of a pediatric asthma CPG across hospital units can safely reduce overall hospital resource intensity by reducing LOS, admissions, ICU services, and charges.

A Critical Asthma Standardized Clinical and Management Plan Reduces Duration of Critical Asthma Therapy

BACKGROUND AND OBJECTIVE

Reduction of critical asthma management time can reduce intensive care utilization. The goal of this study was to determine whether a Critical Asthma Standardized Clinical Assessment and Management Plan (SCAMP) can decrease length of critical asthma management time.

METHODS

This retrospective study compared critical asthma management times in children managed before and after implementation of a Critical Asthma SCAMP. The SCAMP used an asthma severity score management scheme to guide stepwise escalation and weaning of therapies. The SCAMP guided therapy until continuous albuterol nebulization (CAN) was weaned to intermittent albuterol every 2 hours (q2h). Because the SCAMP was part of a quality improvement initiative in which all patients received a standardized therapy, informed consent was waived. The study was conducted in Medicine ICU and Intermediate Care Units in a tertiary care freestanding children's hospital. Children ≥2 years of age who had CAN initiated in the emergency department and were admitted to the Division of Medicine Critical Care with status asthmaticus were included. The time to q2h dosing from initiation of CAN was compared between the baseline and SCAMP cohorts. Adverse events were compared. The Mann-Whitney test was used for analysis; P values <.05 were considered statistically significant.

RESULTS

There were 150 baseline and 123 SCAMP patients eligible for analysis. There was a decrease in median time to q2h dosing after the SCAMP (baseline, 21.6 hours [interquartile range, 3.2-32.3 hours]; SCAMP, 14.2 hours [interquartile range, 9.0-23.1 hours]; P < .01). There were no differences in adverse events or readmissions.

CONCLUSIONS

A Critical Asthma SCAMP was effective in decreasing time on continuous albuterol.
