Systematic review of the use of Statistical Process Control methods to measure the success of pressure ulcer prevention

Clinical evaluation of continuous irrigation with Bikerui combined with negative pressure closed drainage and platelet-rich plasma technique for treatment of stage III-IV pressure ulcer

Introduction

As a catastrophic complication of bedridden and elderly patients, pressure ulcer usually continuously affects patients' health and quality of life, so the daily care of wounds is attached great importance in clinic.

Aim

This work investigated the effect of Bikerui disinfectant + vacuum sealing drainage (VSD) + platelet-rich plasma (PRP) therapy on patients with stage III ~ IV pressure sore.

Material and methods

In this work, 110 patients with pressure ulcer (PU) treated in our hospital were enrolled and were randomly divided into an experimental group (Exp group) and a control group (Ctrl group) by a blind selection method, with 55 cases in each group. Patients in the Ctrl group received surgical debridement + VSD for treatment, while those in the Exp group were treated with Bikerui disinfectant + VSD + PRP. Inflammatory response (IR) score, PU healing (PUH) score, healing time, dressing change frequency (DCF), dressing interval time (DIT), and scar recovery (SR) score of patients in different groups were compared.

Results

The results revealed that the positive rate of bacterial culture in wound secretions in the Exp group was greatly lower than that in the Ctrl group 1 or 2 weeks after treatment (p < 0.05). The IR score in the Exp group was much lower at week 1 and 2 after treatment (p < 0.05). The total effective rate (TER) in the Exp group was obviously higher than that in the Ctrl group (94.55% vs. 76.36%).

Conclusions

The results suggested that Bikerui disinfectant + VSD + PRP therapy could effectively improve the inflammatory degree of PU patients, promote the wound repair and scar recovery of patients, and greatly improve the clinical efficacy of PU patients.

Sonic hedgehog signaling promotes angiogenesis of endothelial progenitor cells to improve pressure ulcers healing by PI3K/AKT/eNOS signaling

BACKGROUND

Pressure ulcer is a severe disease in the paralyzed and aging populations. Endothelial progenitor cells (EPCs) are able to regulate ulcer healing by modulating angiogenesis, but the molecular mechanism is still obscure. Sonic hedgehog (SHH) signaling contributes to angiogenesis in various diseases and has been identified to modulate EPCs function. Here, we aimed to explore the significance of SHH signaling in EPCs function during pressure ulcers.

METHODS

The EPCs were isolated and characterized by the expression of DiI-acLDL and bind fluorescein iso-thiocyanate UEA-1. Cell proliferation was detected by cell counting kit 8 (CCK-8). The DiI-acLDL and bind fluorescein iso-thiocyanate UEA-1 were analyzed by immunofluorescent analysis. The angiogenesis of EPCs was analyzed by tube formation assay. The pressure ulcers rat model was constructed, the wound injury was analyzed by H&E staining and angiogenesis was analyzed by the accumulation of CD31 based on immunofluorescent analysis.

RESULTS

The expression of patched-1 and Gli-1 was enhanced by SHH activator SAG but reduced by SHH inhibitor cyclopamine in the EPCsThe PI3K, Akt, eNOS expression and the Akt phosphorylation were induced by SAG, while the treatment of cyclopamine presented a reversed result. The proliferation and migration of EPCs were enhanced by SAG but repressed by cyclopamine or PI3K/AKT/eNOS signaling inhibitor Y294002, in which the co-treatment of Y294002 could reverse the effect of SAG.

CONCLUSIONS

Thus, we found that SHH signaling activated angiogenesis properties of EPCs to improve pressure ulcers healing by PI3K/AKT/eNOS signaling. SHH signaling may serve as the potential target for attenuating pressure ulcers.

Bridging the Acute-to-Outpatient Care Gap in Mental Health: Developing and Implementing a Mental Health Transition Process

BACKGROUND

A national Department of Veterans Affairs (VA) mental health (MH) quality metric tracks engagement in outpatient MH care after discharge from residential and inpatient settings, with recommendations for 2 or more visits 30 days postdischarge.

LOCAL PROBLEM

A gap in transitioning patients from residential to outpatient MH care was identified at this site.

METHODS

A transition management process was developed and piloted, including a new MH Discharge Consult and an RN Transition Care Managers team.

INTERVENTIONS

Transition Care Managers triaged Discharge Consults, communicated with schedulers and patients pre- and postdischarge, and tracked MH engagement for 30 days postdischarge. Process, outcome, and balancing measures were developed and iteratively adjusted using Plan-Do-Study-Act (PDSA) cycles.

RESULTS

Over 55 weeks, 443 Discharge Consults were placed. There was an average 89% success rate in connecting patients with 2 or more MH visits versus 53% preintervention.

CONCLUSIONS

This pilot showed promising results in improving postdischarge MH engagement with the use of PDSA cycles to collect data and refine processes.

The Contribution of Variable Control Charts to Quality Improvement in Healthcare: A Literature Review

Objective

To conduct a literature review to determine where and how variable control charts have contributed to quality improvement in healthcare.

Methods

A targeted literature search of the ABI/INFORM Global, Science Direct, Medline and Google Scholar databases was conducted, which yielded 6875 papers. Screening articles on the basis of title and abstract resulted in references to 163 articles, leading to the identification of 29 articles published between 1992 and 2019 that met the inclusion criteria. Common themes, variables and units of analysis were then analyzed.

Results

Variable control charts have been applied in 11 different healthcare contexts, using 17 different variables, at various levels within healthcare organizations. The main reason for applying variable control charts is to demonstrate a process change, usually following a specific change or quality intervention. The study identified various limitations and benefits of applying variable control charts. The charts are visually easy to understand for both management and employees, but they are limited by their requirement for potentially complex and resource-intensive data collection.

Conclusion

Variable control charts contribute to quality improvement in healthcare by enabling visualization and monitoring of variations and changes in healthcare processes. The methodology has been most frequently used to demonstrate process shifts after quality interventions. There still is a great potential for more studies applying variable control charts.
