Chest physiotherapy for the prevention of ventilator-associated pneumonia: A meta-analysis

Surveillance and prevention of healthcare-associated infections: best practices to prevent ventilator-associated events

INTRODUCTION

Ventilator associated pneumonia (VAP) leads to an increase in morbidity, mortality, and healthcare costs. In addition to increased evidence from the latest European and American guidelines (published in 2017 and 2022, respectively), in the last two years, several important clinical experiences have added new prevention tools to be included to improve the management of VAP.

AREAS COVERED

This paper is a narrative review of new evidence on VAP prevention. We divided VAP prevention measures into pharmacological, non-pharmacological, and ventilator care bundles.

EXPERT OPINION

Most of the effective strategies that have been shown to decrease the incidence of complications are easy to implement and inexpensive. The implementation of care bundles, accompanied by educational measures and a multidisciplinary team should be part of optimal management. In addition to ventilator care bundles for the prevention of VAP, it could possibly be beneficial to use ventilator care bundles for the prevention of noninfectious ventilator associated events.

Comprehensive Physiotherapy Approach for Pneumonia After Angioplasty in an 83-Year-Old Hypertensive Male Patient: A Case Report

Pneumonia is an infection that causes inflammation in the air sacs of the lungs. Coronary artery disease is a condition characterized by the buildup of plaque in the coronary arteries, which supply blood to the heart. This obstruction restricts blood flow, resulting in chest pain (angina) and, in extreme cases, heart attacks. An important part of successfully treating diseases like peripheral artery disease and coronary artery disease is balloon angioplasty, a commonly used medical procedure for treating narrowed or clogged arteries. An 83-year-old man who had pneumonia after angioplasty was the subject of this case study. The patient had pneumonia after angioplasty, which was managed by proper medications and cardio-respiratory physiotherapy. The patient was intubated and referred for cardio-respiratory physiotherapy. Physiotherapy treatments like mild chest vibrations, suctioning, and bed mobility exercises were given initially. After extubation, physiotherapy treatment continued with deep breathing exercises, coughing techniques, relaxation techniques, and mobility exercises for the upper limbs and lower limbs. Effective physical rehabilitation was necessary in order to minimize complications following angioplasty and allow him to resume his daily activities. Several outcome measures, like the ICU mobility scale, CURB-65 score, and chest X-ray grading scores, were used to monitor the patient's progress during rehabilitation. The benefits of pulmonary rehabilitation programs emphasize the need for tailored approaches in addressing individual patient needs for comprehensive recovery.

Effects of different types and frequencies of early rehabilitation on ventilator weaning among patients in intensive care units: A systematic review and meta-analysis

OBJECTIVE

This study aimed to investigate the effects of different types and frequencies of physiotherapy on ventilator weaning among patients in the intensive care unit (ICU) and to identify the optimal type and frequency of intervention.

DATA SOURCES

PubMed, Cochrane Library, EMBASE, and Airiti Library.

STUDY SELECTION

Randomized controlled trials that provided information on the dosage of ICU rehabilitation and the parameters related to ventilator weaning were included.

DATA EXTRACTION AND MANAGEMENT

Treatment types were classified into conventional physical therapy, exercise-based physical therapy, neuromuscular electrical stimulation (NEMS), progressive mobility, and multi-component. The frequencies were divided into high (≥ 2 sessions/day or NEMS of > 60 minutes/day), moderate (one session/day, 3-7 days/week or NEMS of 30-60 minutes/day), and low (one session/day, < 3 days/week, or NEMS of < 30 minutes/day).

DATA SYNTHESIS

Twenty-four articles were included for systematic review and 15 out of 24 articles were analyzed in the meta-analysis. Early rehabilitation, especially the progressive mobility treatment exerted an optimal effect in reducing the ventilator duration in patients in the ICU (standardized mean difference [SMD] = 0.91; 95% confidence interval [CI] = 0.23-1.58; P < 0.01). Regarding the treatment frequency, the high-frequency intervention did not result in a favorable effect on ventilator duration compared with the moderate frequency of treatment (SMD = 0.75; 95% CI = -1.13-2.64; P = 0.43).

CONCLUSION

Early rehabilitation with progressive mobility is highly recommended to decrease the ventilation duration received by patients in the ICU. Depending on clinical resources and the tolerance of patients, the frequency of interventions should reach moderate-to-high frequency, that is, at least one session per day and 3 days a week.

[Update of the recommendations of the Pneumonia Zero project]

La pandemia por el SARS-Cov-2 ha impactado negativamente en la aplicación de las recomendaciones de Neumonía Zero y se ha acompañado de un incremento de las tasas de Neumonía asociada a ventilación mecánica (NAVM) en las unidades de cuidados intensivos de España. Con el objetivo de disminuir las tasas actuales a 7 episodios por 1000 días de VM, se han actualizado las recomendaciones del proyecto inicial.

Se identificaron, 27 medidas que se clasificaron en 12 medidas funcionales (posición semisentada, higiene estricta de manos, entrenamiento para manipular la vía aérea, valoración diaria de posible extubación, protocolización del destete, traqueostomía precoz, ventilación no invasiva, vigilancia microbiológica, cambio de tubuladuras, humidificación, fisioterapia respiratoria, nutrición enteral postpilórica), 7 mecánicas (control de la presión del neumotaponamiento, tubos con aspiración subglótica, nutrición con sondas de bajo calibre/en intestino delgado, aspiración de secreciones con circuitos cerrados/abiertos, filtros respiratorios, cepillado de dientes, técnicas de presión negativa en la aspiración de secreciones) y 8 farmacológicas (descontaminación selectiva digestiva, descontaminación orofaríngea, ciclo corto de antibióticos, higiene de boca con clorhexidina, antibióticos inhalados, rotación de antibióticos, probióticos, anticuerpos monoclonales).

Cada medida se analizó de forma independiente, por al menos dos miembros del grupo de trabajo, mediante una revisión sistemática de la literatura y una revisión iterativa de las recomendaciones de las sociedades científicas y/o grupos de expertos.

Para la clasificación de la calidad de la evidencia y fuerza de las recomendaciones se siguió la propuesta del grupo GRADE. Para determinar el grado de recomendación, cada medida fue puntuada por todos los miembros del grupo de trabajo en relación con su efectividad, tolerabilidad y aplicabilidad en las UCI españolas a corto plazo de tiempo. Se solicitó el apoyo de expertos externos en alguna de las medidas que se revisaron. Se seleccionaron aquellas medidas que alcanzaron la máxima puntuación.

Correlation of ICU Nurses' Cognitive Level with Their Attitude and Behavior toward the Prevention of Ventilator-Associated Pneumonia

Objective

To analyze the correlation of ICU nurses' cognitive level with their attitude and behavior toward the prevention of ventilator-associated pneumonia (VAP).

Methods

A total of 90 ICU nurses working in the adult internal medicine ICU, adult surgery ICU, subacute respiratory care ward, etc. from January 2018 to June 2019 were chosen as the subjects to carry out questionnaire survey with the cognition scale, and the correlation analysis on their cognitive level, attitude, and behavior toward the prevention of VAP was conducted.

Results

The linear fitting analysis finding showed that the cognitive level presented a positive correlation with the attitude score and behavior score (R ² = 0.668, 0.734).

Conclusion

Improving ICU nurses' cognitive level, attitude, and behavior toward preventing VAP is conducive to the upgrade of their quality of nursing services. In addition, the ICU nurses' cognitive level is positively correlated with their attitude and behavior.

Risk Factors and Nursing Countermeasures of Ventilator-Associated Pneumonia in Children in the Intensive Care Unit

Objective

This study discussed and analyzed the risk factors and nursing countermeasures of ventilator-associated pneumonia (VAP) in the children intensive care unit (ICU).

Methods

In this study, 155 children with mechanical ventilation in the pediatric intensive care unit from Oct. 2018 to Oct. 2020 were chosen as research objects. We retrospectively analyzed the clinical data of children and divided them into VAP groups and non-VAP groups according to the occurrence of VAP. Subsequently, we adopted a univariate and multivariate logistic regression model to analyze and clarify the risk factors of VAP and formulated the corresponding nursing countermeasures.

Results

49 cases of total research objects had occurred VAP, with an infection rate of 31.62%. The primary pathogenic bacteria were Gram-negative bacteria (43/70, 61.43%). According to multivariate logistic regression analysis, the duration of mechanical ventilation, invasive procedures, and application of hormones and antacids are all independent risk factors for VAP in pediatric ICU. The VPA group had longer hospital stay than the non-VAP group, and the difference was statistically significant ((20.92 ± 4.16)d, (15.24 ± 3.77)d, t = 8.4383, P ≤ 0.001). The hospitalization cost of the VPA group was substantially higher than that of the non-VAP Group ((45.8 ± 10.4) thousand Yuan, (33.2 ± 4.3) thousand Yuan, t = 10.6822, P ≤ 0.001).

Conclusion

Children admitted to the pediatric ICU have a high VAP incidence. The primary pathogenic bacteria are Gram-negative bacteria. As the occurrence of VAP is closely related to a variety of factors, we should take targeted nursing countermeasures to reduce the duration of mechanical ventilation and the frequency of invasive operations and use the hormone and antacids rationally to reduce the risk of VAP and improve the prognosis.

Recommendations to improve insurance coverage for physiotherapy services in Iran: a multi criteria decision-making approach

BACKGROUND

High toll of traffic-related injuries, climate change, natural disasters, population aging, as well as chronic diseases have all made considerable demands on receiving physiotherapy services in Iran. Nevertheless, there is an assortment of complications facing utilization of such services, particularly poor insurance coverage. Therefore, the present study investigated and identified gaps in insurance coverage in order to inform future policy reforms and the design of a more comprehensive and universal benefits package for physiotherapy services in Iran.

METHODS

This project was carried out in Iran, using a mix-methods (viz. qualitative-quantitative) approach. Within the first phase, a qualitative study was completed to find policy recommendations. Such recommendations were then prioritized through the Analytical Hierarchy Process (AHP), in the second phase, based on effectiveness, acceptability, cost, fairness, feasibility, and time.

RESULTS

Within the first phase, a total number of 30 semi-structured interviews with health policy-makers, health insurers, faculty members, rehabilitation experts, and physiotherapists were completed. Several policy recommendations were also proposed by the study participants. Following the second phase, prioritized recommendations were provided to promote stewardship (e.g., informing policy-makers about physiotherapy services), collection of funds (e.g., placing value-added taxes on luxury goods and services), pooling of funds (e.g., moving allocated resources towards insurance (viz. third-party) mechanism), purchasing (e.g., using strategic purchasing), and benefit package (e.g., considering preventive interventions) as the main components of insurance coverage.

CONCLUSION

The study findings provided a favorable ground to improve insurance coverage for physiotherapy services in Iran. As well, decision- and policy-makers can place these recommendations on the agenda in the health sector to protect population health status, especially that of groups with disabilities.

The Role of Dysbiosis in Critically Ill Patients With COVID-19 and Acute Respiratory Distress Syndrome

In late December 2019, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) quickly spread worldwide, and the syndrome it causes, coronavirus disease 2019 (COVID-19), has reached pandemic proportions. Around 30% of patients with COVID-19 experience severe respiratory distress and are admitted to the intensive care unit for comprehensive critical care. Patients with COVID-19 often present an enhanced immune response with a hyperinflammatory state characterized by a "cytokine storm," which may reflect changes in the microbiota composition. Moreover, the evolution to acute respiratory distress syndrome (ARDS) may increase the severity of COVID-19 and related dysbiosis. During critical illness, the multitude of therapies administered, including antibiotics, sedatives, analgesics, body position, invasive mechanical ventilation, and nutritional support, may enhance the inflammatory response and alter the balance of patients' microbiota. This status of dysbiosis may lead to hyper vulnerability in patients and an inappropriate response to critical circumstances. In this context, the aim of our narrative review is to provide an overview of possible interaction between patients' microbiota dysbiosis and clinical status of severe COVID-19 with ARDS, taking into consideration the characteristic hyperinflammatory state of this condition, respiratory distress, and provide an overview on possible nutritional strategies for critically ill patients with COVID-19-ARDS.

Effectiveness of chest physiotherapy using passive slow expiratory techniques in dogs with airway fluid accumulation: A randomized controlled trial

BACKGROUND

Prolonged slow expiration (PSE) and assisted cough (AC) are airway clearance techniques feasible and well tolerated in dogs.

OBJECTIVES

To evaluate the effectiveness of PSE and AC as chest physiotherapy (CP) techniques in dogs with airway fluid accumulation.

ANIMALS

Thirty-one client-owned dogs hospitalized in an intensive care unit from October 2014 to May 2018.

METHODS

Prospective randomized controlled trial. Dogs presented with or developing acute dyspnea during hospitalization associated with airway fluid accumulation were assigned to CP group (medical treatment and CP, 15 dogs) or control group (medical treatment alone, 16 dogs). The arterial partial pressure of oxygen (PaO2 ) to fraction of inspired oxygen (FiO2 ) ratio (P/F ratio; PaO2 /FiO2 × 100) was calculated daily for the 1st 48 hours of hospitalization and using the last arterial blood gas performed before discharge or death. The ratio of days of hospitalization with oxygen/total number of hospitalization days (ratio of oxygen-free-days [O2 Free]) was calculated.

RESULTS

During the 1st 48 hours, the P/F ratio increased significantly in the CP group compared to the control group (+ 35.1 mm Hg/day; 95% confidence interval [CI] = 0.4-57.5; P = .03). The (median; 1st quartile to 3rd quartile) difference between the P/F ratio at discharge and inclusion was significantly higher in the CP group (178 mm Hg; 123-241) than in the control group (54 mm Hg; -19 - 109; P = .001). Mean O2 Free increased by 46.4% in the CP group compared with control group (95% CI = 16-59; P = .001). Mortality was 13% (2/15) in the CP group and 44% (7/16) in the control group (P = .07).

CONCLUSIONS AND CLINICAL IMPORTANCE

Prolonged slow expiration and AC improved P/F ratio within 48 hours and decreased need for oxygenation in dyspneic dogs with acute airway fluid accumulation.

Efficacy of Venner-PneuX endotracheal tube system for prevention of ventilator-associated pneumonia in intensive care units: A protocol for systematic review and meta-analysis

BACKGROUND

The pathogenic mechanism and prevention of ventilator-associated pneumonia (VAP) are substantially improved over the past several decades, but VAP remains frequently seen among the critical cases. The Venner-PneuX endotracheal tube system (VPXETS) has been proved to perform better than standard endotracheal tubes (SET) in the prevention of VAP in some studies. Therefore, this systematic review is aimed at evaluating the effectiveness of VPXETS in order to prevent VAP.

METHODS

Electronic databases, including PubMed, WANFANG, CENTRAL, CNKI, EMBASE, and CINAHL, are used to search relevant randomized controlled trials for evaluating the therapeutic effect of VPXETS on preventing VAP from January 2011 to December 2020. To be specific, related studies are selected, data are extracted, risk of bias is assessed, and meta-analysis is conducted in succession.

RESULTS

The present review aims to assess the therapeutic effect of VPXETS on preventing VAP in intensive care units (ICUs). Our outcome measures include the incidence and side reaction of VAP.

CONCLUSIONS

The present review assesses related studies regarding the therapeutic effect of VPXETS on preventing VAP at ICUs.

DISSEMINATION AND ETHICS

Our findings in this work are to be disseminated by means of peer-reviewed publication. No ethical approval is required in our review since it uses the published data. Moreover, anonymity is guaranteed during the data analysis process.

Mechanical Insufflation-exsufflation for the Prevention of Ventilator-associated Pneumonia in Intensive Care Units: A Retrospective Cohort Study

Aim

Ventilator-associated pneumonia (VAP) is the most common intensive care unit (ICU)-acquired infection. The current study aimed to assess the efficacy of mechanical insufflation-exsufflation (MI-E) in preventing VAP in critically ill patients.

Materials and methods

This retrospective cohort study was conducted at the ICU of Chiba University Hospital between January 2014 and September 2017. The inclusion criteria were patients who required invasive mechanical ventilation ≥48 hours and those who underwent rehabilitation, including chest physical therapy (CPT). In 2015, the study institution started the use of MI-E in patients with impaired cough reflex. From January to December 2014, patients undergoing CPT were classified under the historical control group, and those who received treatment using MI-E from January 2015 to September 2017 were included in the intervention group. The patients received treatment using MI-E via the endotracheal or tracheostomy tube, with insufflation-exsufflation pressure of 15-40 cm H₂O. The treatment frequency was one to three sessions daily, and a physical therapist who is experienced in using MI-E facilitated the treatment.

Results

From January 2015 to September 2017, 11 patients received treatment using MI-E. Of the 169 patients screened in 2014, 19 underwent CPT. The incidence of VAP was significantly different between the CPT and MI-E groups (84.2% [16/19] vs 26.4% [3/11], p = 0.011). After adjusting for covariates, a multivariate logistic regression analysis was performed, and results showed that the covariates were not associated with the incidence of VAP.

Conclusion

This retrospective cohort study suggests that the use of MI-E in critically ill patients is independently associated with a reduced incidence of VAP.

Clinical significance

Assessing the efficacy of MI-E to prevent VAP.

Clinical study of Dysfunctional Ventilatory Weaning Response in critically ill patients

Objective:

to clinically validate the nursing diagnosis of Dysfunctional Ventilatory Weaning Response in adult patients admitted to Intensive Care Units.

Method:

a concurrent cohort performed with 93 patients admitted to Intensive Care Units. The incidence and incidence density of the diagnosis were estimated, its related factors were identified based on bivariate analysis and clinical indicators for determining its occurrence, according to the global and temporal presentation.

Results:

the overall incidence of the diagnosis was 44.09% and the incidence density was 14.49 occurrences for every 100 extubations/day. The factors related to the diagnosis were the following: age, clinical severity, fluid balance, oliguria, hemodialysis, edema in upper/lower limbs, anasarca, number of antibiotics, hypothermia, hyperthermia, amount of secretion, muscle retraction, anxiety score, heart rate, use of vasopressors and non-invasive ventilation after extubation. The clinical indicators most frequently identified for determining the diagnosis were the following: tachypnea, drop of saturation and tachycardia. Temporal progression in the severity of these manifestations was found.

Conclusion:

the Dysfunctional Ventilatory Weaning Response is a common finding in critically ill patients. Some components of the diagnosis of the NANDA-International (2018) version could be clinically validated. It is noteworthy that there are variables not yet described in the taxonomy, demonstrating the need to review this nursing diagnosis.
