Improving Asthma Control Test completion rates across a multi-site pediatric pulmonary clinic network: a quality improvement initiative.

OBJECTIVE: Assessing asthma control is an essential part of the outpatient management of children with asthma and can be performed through validated questionnaires such as the Asthma Control Test (ACT). Systematic approaches to incorporating the ACT in outpatient visits are often lacking, contributing to inconsistent completion rates. We conducted a quality improvement initiative to increase the proportion of visits where the ACT is completed for children with asthma in our multi-site pediatric pulmonary clinic network. METHODS: We developed an intervention of sending the ACT questionnaire to patients and caregivers through the electronic patient portal to complete prior to their visits. This strategy was first piloted at one clinic beginning in July 2020 and then expanded to 5 other clinics in the network in October 2020. Our outcome measure was average monthly proportion of visits with a completed ACT, tracked using statistical process control charts. The process measure was method of ACT completion tracked using run charts. RESULTS: At the pilot clinic, average monthly completion rate rose within 3 months of the intervention from 27% to 72% and was sustained more than 22 months. Completion across all clinics increased from 57% pre-intervention to 76% post-intervention. Importantly, the intervention did not rely on clinic staff to administer the questionnaire and did not interfere with existing clinic flow. CONCLUSION: An intervention of delivering the ACT electronically to patients and caregivers for completion prior to visits led to a rapid and sustained improvement in ACT completion rates across a large, pediatric pulmonary clinic network.

Double-row staple technology versus triple-row staple technology for colorectal surgery: A systematic review and meta-analysis.

BACKGROUND: Some observational data have suggested that anastomotic leak may be reduced with triple-row staple technology compared to double-row staple technology. We aimed to investigate this further by performing a systematic review comparing double- and triple-row staple technology for colorectal anastomoses. METHODS: This systematic review was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases were searched up to November 2023. Articles were eligible for inclusion if they were comparing double-row staple and triple-row staple technology for left-sided colo-colic, colorectal, or coloanal anastomosis. The main outcomes included anastomotic leak, anastomotic hemorrhage, 30-day mortality, and reoperation. Meta-analyses with inverse variance random effects were performed. Certainty of evidence was assessed with Grading of Recommendations, Assessment, Development, and Evaluations. RESULTS: After reviewing 340 relevant citations, 6 retrospective cohort studies met inclusion. Overall, 19,372 patients (mean age: 60.2 years, 52.7% female sex) had anastomoses with double-row staple technology, and 2,298 patients (mean age: 61.3 years, 50.3% female sex) with triple-row staple technology. Most operations were anterior resections (double-row: 55.3%; triple-row: 43.6%). Across all included studies, the risk of anastomotic leak was reduced with triple-row staple technology (6.3% vs 7.5%, risk ratio 0.54, 95% confidence interval 0.31-0.94, P = .03, I2=75%). There were no significant differences in anastomotic hemorrhage (risk ratio 0.47, 95% confidence interval 0.15-1.49, P = .20, I2 = 57%), 30-day mortality (risk ratio 0.66, 95% confidence interval 0.17-2.55, P = .55, I2 = 0%), or reoperation (risk ratio 1.05, 95% confidence interval 0.42-2.64, P = .91, I2 = 56%). CONCLUSION: Triple-row staple technology may reduce the risk of anastomotic leak in left-sided colorectal anastomoses.

Human Papillomavirus Vaccine Completion by 13: A Quality Improvement Initiative in a Large Primary Care Network.

OBJECTIVE: Fewer than 40% of U.S. children complete the human papillomavirus (HPV) vaccine series before their 13th birthday. In our large pediatric primary care network, HPV vaccine completion rate by age 13 was 30%. We hypothesized that a phased quality improvement (QI) initiative would increase rates of HPV vaccine completion by age 13 across our network. METHODS: This QI initiative was conducted in a network of 30 practices located across two states, in urban and suburban settings, consisting of teaching and non-teaching clinics, and ranging in size from three to 50 providers per office. We used a phased approach incorporating multicomponent network-wide and iterative practice-specific interventions. Key interventions included: updating clinical decision support to default order HPV vaccine due at preventive visits starting at age nine instead of 11, data audit and feedback to providers and practices, encouraging use of a strong provider recommendation, and standing orders. RESULTS: From April 2019 to October 2022, HPV vaccine completion by age 13 across our network increased from 30% to 55% and met criteria for special cause variation on statistical process control charts. A gap in median HPV vaccine completion by age 13 between patients with public insurance and patients with private or commercial insurance decreased from 9% to 1%. CONCLUSION: A QI initiative was associated with a sustained increase in HPV vaccine series completion by age 13 and reduced variation in care across a large network of 30 primary care practices.

Implementation of a Clinical Decision Support (CDS) Tool for the Management of Functional Constipation in Pediatric Primary Care.

Constipation is common in general pediatrics and often results in potentially unnecessary referrals to pediatric gastroenterology. We hypothesized that a clinical decision-making tool would support primary care providers to manage pediatric constipation, improve workflow, and prevent unnecessary subspecialty care. In this pilot quality improvement initiative, a multidisciplinary team completed a root cause analysis related to challenges with the care of pediatric constipation. The results informed the development of interventions including a Clinical Decision Support tool and patient educational materials embedded within an existing order-set in the electronic health record, which we implemented in our primary care network. The use of the updated order-set continues to increase monthly, and there is reported improved workflow and increased confidence by providers. These interventions demonstrated that it is feasible to implement tools to support primary care clinicians in their management of pediatric patients with constipation.

Stage-Specific Generation of Human Pluripotent Stem Cell Derived Lung Models to Measure CFTR Function.

Human embryonic stem cells (ES) and induced pluripotent stem cells (iPSC) are powerful tools that have the potential to generate in vitro human lung epithelial cells. However, challenges in efficiency and reproducibility remain in utilizing the cells for therapy discovery platforms. Here, we optimize our previously published protocols to efficiently generate three developmental stages of the lung model (fetal lung epithelial progenitors, fLEP; immature airway epithelial spheroid, AES; air-liquid interface culture, ALI), and demonstrate its potential for cystic fibrosis (CF) drug discovery platforms. The stepwise approach directs differentiation from hPSC to definitive endoderm, anterior ventral foregut endoderm, and fetal lung progenitor cells. The article also describes the generation of immature airway epithelial spheroids in Matrigel with epithelial cells sorted by a magnetic-activated cell sorting system, and the generation of adult-like airway epithelia through air-liquid interface conditions. We demonstrate that this optimized procedure generates remarkably higher cystic fibrosis transmembrane conductance regulator (CFTR) expression and function than our previous method, and thus is uniquely suitable for CF research applications. © 2022 The Authors.

A Developmental Role of the Cystic Fibrosis Transmembrane Conductance Regulator in Cystic Fibrosis Lung Disease Pathogenesis.

The cystic fibrosis (CF) transmembrane conductance regulator (CFTR) protein is a cAMP-activated anion channel that is critical for regulating fluid and ion transport across the epithelium. This process is disrupted in CF epithelia, and patients harbouring CF-causing mutations experience reduced lung function as a result, associated with the increased rate of mortality. Much progress has been made in CF research leading to treatments that improve CFTR function, including small molecule modulators. However, clinical outcomes are not necessarily mutation-specific as individuals harboring the same genetic mutation may present with varying disease manifestations and responses to therapy. This suggests that the CFTR protein may have alternative functions that remain under-appreciated and yet can impact disease. In this mini review, we highlight some notable research implicating an important role of CFTR protein during early lung development and how mutant CFTR proteins may impact CF airway disease pathogenesis. We also discuss recent novel cell and animal models that can now be used to identify a developmental cause of CF lung disease.

Gene therapy for cystic fibrosis: new tools for precision medicine.

The discovery of the Cystic fibrosis (CF) gene in 1989 has paved the way for incredible progress in treating the disease such that the mean survival age of individuals living with CF is now ~58 years in Canada. Recent developments in gene targeting tools and new cell and animal models have re-ignited the search for a permanent genetic cure for all CF. In this review, we highlight some of the more recent gene therapy approaches as well as new models that will provide insight into personalized therapies for CF.
