Lung ultrasound in respiratory therapy: a global reflective survey.

BACKGROUND: Lung ultrasound (LUS) is a non-invasive point of care diagnostic tool used to assess the presence and severity of various lung disorders for more than two decades. Within the healthcare professionals are the respiratory therapists (RTs) who play a vital role in managing ventilated and other patients requiring respiratory support, but the incorporation of LUS into their scope of practice has not been well highlighted. This international cross-sectional survey was specifically designed to evaluate the knowledge, attitude, and practice of RTs with respect to LUS. METHODS: This observational cross-sectional study was conducted among RTs from different parts of the world using a questionnaire-based study tool. 514 RTs responded to all the questions and were considered for statistical analysis. Descriptive statistics, Analysis of variance, Fisher's exact, Chi-square, Bonferroni post-hoc analysis, and Binomial logistic regression analyses were performed to identify the significance of the data. RESULTS: From 22 countries, 514 RTs responded to the survey, with the major share from the middle eastern countries. Out of the 514 responders, 44.9% of the responders were in the age group of 23-30 years; 67.1% were bachelor's degree holders; and 40.9% of participants had more than 10 years of experience. The knowledge-based questions revealed that RTs with higher experience and academic qualification provided more positive responses. While in the attitude-related domain it is observed that standardized training in LUS helps them to enhance the current practice and to add LUS to the academic curriculum of respiratory therapy schools; however there remains barriers to practice LUS based on their responses. The practice-based questions revealed that RTs expect some additional seminars/workshops/webinars to be done on LUS frequently. More than half of the participants are found to be knowledgeable with a positive attitude and working towards the inclusion of LUS in respiratory therapy profession. CONCLUSION: It is concluded that respiratory therapists have a positive attribute towards the inclusion of lung ultrasound in their clinical practice. Providing more structured training for professional respiratory therapists and including lung ultrasound modules in the respiratory therapy school curriculum may facilitate mastering their diagnostic skills, thereby expanding the scope of practice.

Quality indicators in respiratory therapy.

Quality indicators in healthcare refer to measurable and quantifiable parameters used to assess and monitor the performance, effectiveness, and safety of healthcare services. These indicators provide a systematic way to evaluate the quality of care offered, and thereby to identify areas for improvement and to ensure that patient care meets established standards and best practices. Respiratory therapists play a vital role in areas of clinical administration such as infection control practices and quality improvement initiatives. Quality indicators serve as essential metrics for respiratory therapy departments to assess and enhance the overall quality of care. By systematically tracking and analyzing indicators related to infection control, treatment effectiveness, and adherence to protocols, respiratory care practitioners can identify areas to improve and implement evidence-based changes. This article reviewed how to identify, implement, and monitor quality indicators specific to the respiratory therapy departments to set benchmarks and enhance patient outcomes.

Psychometric properties and development of a structured questionnaire to assess the perception, attitude, and job satisfaction among respiratory therapists.

Background: Over the past ten years, significant transformations have occurred in the healthcare landscape, presenting respiratory therapists (RTs) with a mix of challenges and opportunities. Hence, their perceptions about career progression and job satisfaction will be critical factor in determining the recruitment and retention of RTs. However, there are no studies in the literature that comprehensively assessed these aspects using a reliable and valid measure specific to RTs. Our objective was to develop and psychometrically test a Standardized Questionnaire (SQ) for evaluating RT's overall job satisfaction. Methods: Following consultations with experts and interviews conducted with RTs, a preliminary questionnaire was devised for the purpose of exploratory factor analysis (EFA). The 49 items of the Structured Questionnaire (SQ) were used for verification of the theorized factor structure and content validity using a confirmatory factor analysis (CFA). Principal Component Analysis (PCA), Structural Equation Modeling (SEM), and Confirmatory Factor Analysis (CFA) for the global fit were done. Cronbach's alpha was performed to estimate the internal consistency. The samples of RTs were collected from India between August 2021 and January 2022. Results: A convenience sample comprising 409 respiratory therapists (RTs) employed in India participated in the survey conducted from June 2021 to January 2022. The exploratory factor analysis revealed three factors that explained 61.2 % of the total variance. The confirmatory factor analysis yielded a 3-factor structure (X2/df = 4.4, p < 0.02, standardized root-mean-square residual = 0.05, goodness of fit index = 0.94, comparative fit index = 0.98). The Cronbach's alpha was 0.94 for the total scale. Conclusions: Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) are becoming more prevalent, especially in the development and psychometric evaluation of instruments. This Structured Questionnaire is a reliable and valid tool that has utility for assessing perceptions, satisfaction, and attitude among Respiratory Therapists and for making comparisons of similar psychometric measures.

Rate of Change of Rapid Shallow Breathing Index and Extubation Outcome in Mechanically Ventilated Patients.

Background: Rapid shallow breathing index (RSBI) has been widely used as a predictor of extubation outcome in mechanically ventilated patients. We hypothesize that the rate of change of RSBI between the beginning and end of a 120-minute spontaneous breathing trial (SBT) could be a better predictor of extubation outcome than a single RSBI measured at the end of SBT in mechanically ventilated patients. Methodology. In this prospective observational study, we enrolled 193 patients who met the inclusion criteria, of whom 33 patients were unable to tolerate a 120-minute SBT and were excluded from the study. The study population consisted of 160 patients, categorized into three subgroups: patients with normal lung (no reported history of respiratory diseases), patients with airway disease, and patients with parenchymal disease who completed 120 minutes of SBT on low levels of pressure support ventilation. RSBI was obtained from the ventilator display at the 5th and the 120th minutes of SBT. The rate of change of RSBI (RSBI 5-120) was calculated as (RSBI 2-RSBI 1)/RSBI 1 × 100. Receiver-operating characteristic (ROC) curves were plotted for RSBI 5-120 and RSBI 120 in all patients and among the three subgroups (normal group, airway group, and parenchymal group) to compare the superiority of their best thresholds in predicting extubation failure. Results: The RSBI 5-120 threshold for extubation failure in the entire patient group was 23% with an overall accuracy of 88% (AUC = 0.933, sensitivity = 91%, and specificity = 86%) and the threshold of RSBI 120 for extubation failure in the entire patient group was 70 breaths/min/L with an overall accuracy of 82% (AUC = 0.899, sensitivity = 85%, and specificity = 81%). In patients in the normal lung group, the threshold of RSBI 5-120 was 22%, with an overall accuracy of 89% (AUC = 0.892, sensitivity = 87.5%, and specificity = 90%), and the RSBI 120 threshold was 70 breaths/min/L, with an overall accuracy of 89% (AUC = 0.956, sensitivity = 88%, and specificity = 90%). The RSBI 5-120 threshold in patients with airway disease was 25% with an accuracy of 86% (AUC = 0.892, sensitivity = 85%, and specificity = 86%) and the threshold of RSBI 120 was 73 breaths/min/L with an accuracy of 83% (AUC = 0.874, sensitivity = 85%, and specificity = 82%). In patients in the parenchymal disease group, the threshold of RSBI 5-120 was 24%, with an accuracy of 90% (AUC = 0.966, sensitivity = 92%, and specificity = 89%) and RSBI 120 threshold was 71 breaths/min/L, which was 88% accurate (AUC = 0.893, sensitivity = 85%, and specificity = 89%). Conclusion: The rate of change of RSBI between the 5th and 120th minutes was moderately more accurate than the single value of RSBI measured at the 120th minute in predicting extubation outcome.

Routine Application of Lung Ultrasonography in Respiratory Care: Knowledge, Perceptions, and Barriers to Instigate.

Background: Lung Ultrasound (LUS) had proved to be beneficial in detecting respiratory disorders at the bedside. Understanding the important role of Respiratory Therapists (RTs) in the critical care, we aimed to assess their knowledge, perceived relevance of LUS to clinical practice, current skill gaps, and barriers to practice. Methods: A cross-sectional, nationwide survey conducted among the RTs working in the Kingdom of Saudi Arabia. The validated questionnaire included 4 sections; the demographics, knowledge and perceptions, applicability and self-reported proficiency, and barriers to the use of LUS by RTs. Results: A total of 256 RTs across different regions of Saudi Arabia participated in this survey. 71.9% of them were males, and 46.1% of the participants were having <5 years of working experience. Only (18.1%) of the participants used LUS in their clinical practice, and (43%) of them had never received any training. 66% of the participants perceived LUS as an effective tool in the RT practice and immensely valuable in their daily practice (70%). A large proportion of RTs perceived LUS to be ineffective in calculating the lung score (50.4%), assessing the diaphragm (40.2%), and detecting pulmonary edema (38.3%). Calculating lung score has a lower mean score of 2.55 on both skills, and identifying its applicability to clinical practice with a mean score of 2.71 than other indications. Lack of training and curriculum (154/256; 60.2%) remains the top barrier that prevented RTs from using LUS in their clinical practice. Conclusion: While many RTs in Saudi Arabia perceived LUS as an effective tool in the RT practice, considerable competence gap exist, indicating the need for LUS training. There is a need for incorporating LUS into the curriculum of RT schools and promoting competency-based training for the current RT workforce to help improve patient care.

Quality assurance in allied healthcare education: A narrative review.

Introduction: There is no standard methodology for outlining the intricacies of allied healthcare education (AHE) or its quality. The profound misconception is that quality assurance (QA) in AHE is used on a "voluntary" basis. Given the absence of statutory regulatory mechanisms such as accreditation, validation, and audit by the peripheral agencies concerning QA, adoption of QA measures in AHE is not consistent, and it results in producing a subpar allied health workforce. This paper analyzes the need to include QA measures as an essential domain in evaluating the effectiveness of allied health professional education programs. Method: A large database search was performed using pertinent terms, and a blueprint was developed for a meticulous literature review published between 2015 and 2021. Five hundred eighty-two articles were found and screened; a critical appraisal was performed for 22 peer-reviewed articles for relevant information. Results: The literature review identified the need to use academic domains such as leadership, planning, delivery, and feedback as QA criteria to evaluate the efficiency of education and training in allied health professional education programs. Instructors and facilitators for specific knowledge and skill development and a description of their roles should also be used in QA evaluation. Conclusion: Resources for effective learning and teaching in the allied healthcare domain are limited. This review highlights the significant need to include a QA system in AHE, considering the pivotal role of these students in supporting humankind, now and in the future. The findings contribute to the research by providing essential insights into current trends and focusing on existing research in AHE quality.

Quality Management in Respiratory Care.

The word "quality" refers to the features of a product or service to which a certain value is ascribed. When it comes to hospital-based practices, quality has often been considered to be specific to the care provided. However, this specific perspective is transitioning toward a broader concept after the evolution of quality-improvement projects and quality frameworks at the organizational level. Respiratory therapy departments have been identified as an essential part of any hospital because the key nature of discipline for respiratory therapists is widely understood. Due to their professional accountability and professional values, respiratory therapists often have administrative roles in infection control practices and quality-improvement projects. Therefore, it would be ideal to have a core team of respiratory therapists trained in quality management and to initiate quality-improvement processes at the departmental level. Every respiratory therapy department should have its own quality-improvement team to assist with the process of training, implementation, and analysis. Thus, this article aimed to discuss the role of respiratory therapists and respiratory therapy departments in quality-improvement processes and projects to set benchmarks and enhance outcomes.

Lung Ultrasound: The Emerging Role of Respiratory Therapists.

Lung ultrasound is a point-of-care imaging tool that is routinely used in acute care medicine. Traditionally, radiology physicians were the primary practitioners of diagnostic ultrasound, but with the recognition of its importance in intensive care medicine, critical care physicians have also adopted this practice. Within the intensive care unit inter-professional team is the respiratory therapist, who participates actively in the care of ventilated patients. Their scope of responsibility is expanding with newer technologies being brought into clinical use on a regular basis. This review focuses on the scope and benefits of ultrasound training within respiratory care-related areas.

Rapid shallow breathing index.

Predicting successful liberation of patients from mechanical ventilation has been a focus of interest to clinicians practicing in intensive care. Various weaning indices have been investigated to identify an optimal weaning window. Among them, the rapid shallow breathing index (RSBI) has gained wide use due to its simple technique and avoidance of calculation of complex pulmonary mechanics. Since its first description, several modifications have been suggested, such as the serial measurements and the rate of change of RSBI, to further improve its predictive value. The objective of this paper is to review the utility of RSBI in predicting weaning success. In addition, the use of RSBI in specific patient populations and the reported modifications of RSBI technique that attempt to improve the utility of RSBI are also reviewed.
