  Abstract 


Background: The deadly outbreak of coronavirus disease 2019 (COVID-19) has imposed many challenges to health-care professionals (HCPs). The knowledge, confidence in performing clinical skills, and psychological impact have been studied among various HCP. Respiratory therapists (RTs) are the frontliners in handling critically ill COVID-19 victims. Although being an integral part, there are no studies on RTs in COVID-19. Hence, we aim to study the knowledge, confidence, and perception of RTs in managing COVID-19. Subjects and Methods: A cross-sectional, questionnaire-based survey conducted among RTs in India. The present study was conducted from July 15, 2020, to August 1, 2020. Descriptive analysis was used to describe demographics, mean knowledge, confidence levels, perception, and psychological impact on RTs. Results: A total of 68 RTs responded with a response rate of 70.8%. Of them, 60% (41) had good knowledge, 96% (65) had higher confidence in performing required clinical skills, 98.5% (67) had a perception that RTs plays an essential role in COVID-19 care, and 98.5% (67) had a negative psychological impact. Reliability of the questionnaire was found to be in acceptable range. Conclusions: This study found that RTs in general had good knowledge and higher level confidence in performing procedure related to COVID-19. RTs perceive that the role of RT in COVID-19 is important.

  Introduction Top


The coronavirus disease 2019 (COVID-19) caused by “Severe Acute Respiratory Syndrome Coronavirus 2” (SARS-CoV-2) started in Wuhan, China. On March 11, 2020, the World Health Organization (WHO) declared COVID-19 as a pandemic disease. As per the weekly operational report of COVID-19 by the WHO published on November 6, 2020, there were 48,534,508 confirmed cases and at least 1,231,017 deaths worldwide.[1] In India, the first case of COVID-19 was detected in Kerala on January 30, 2020, and the cases are steadily increasing, and at present, there 8,591,730 confirmed cases with 127,059 deaths.[2]

Health-care professionals (HCPs), including doctors, nurses, and respiratory therapists (RTs), are the frontliners in the care of critically ill COVID-19 patients. Rigorous training about the disease was given to all HCPs through online platform to increase their knowledge, awareness, and practice skills for better management of this disease. RTs are integral part of core team in managing COVID-19. RTs are called as “unsung heroes” in the COVID-19 pandemic by a US magazine.[3] The current pandemic has led to an increased awareness of RT profession in many parts of the world, and public health-care system has started recognizing the importance of RTs.

Majority of COVID-19 patients with respiratory symptoms progresses to pneumonia, severe pneumonia, acute respiratory distress syndrome, sepsis, and septic shock. Respiratory failure requiring oxygen support and/or mechanical ventilation is the characteristic feature of SARS CoV 2 infection. Care of the patient requires not only the equipment and facilities but also the expertise of a trained RT.

Knowledge of a disease greatly influences the attitude and practice of a HCP in the management of a disease. The current pandemic has led to overburden on HCP due to the shortage of trained personal which has caused a negative psychological impact. To evaluate this, several questionnaires based surveys on COVID-19 have been done among specific HCP such as doctors, nurses, and pharmacists.[4],[5],[6] As per our knowledge, there are no studies done specifically among RTs. The aim of our study is to evaluate the RTs knowledge on COVID-19, confidence in performing a specific clinical skill desired in COVID-19 care, perception, and psychological stress levels of RT's while managing COVID-19.


  Subjects and Methods Top


Study design and approvals

This was a cross-sectional, questionnaire study with snow ball sampling conducted from July 15, 2020, to August 1, 2020. The present study was approved by the Institutional Research Committee and Institutional Ethics Committee (IEC 389-2020) and registered in the Clinical Trial Registry of India (CTRI/2020/07/026444). Electronic informed consent was obtained from each participant before data collection. Participants were free to withdraw from the survey anytime without providing justification.

Study participants

The participants were the qualified (either diploma, graduate, or postgraduate) RTs working in India in different geographic locations. During the time of the study, the confirmed COVID-19 cases were steadily increasing in the country, and some states were spiking the records. RTs were identified in each region, and the online questionnaire was sent through E-mail/WhatsApp. On clicking the link, the participants were directed to informed consent, following which the participants were allowed to fill the questionnaire. The respondents were encouraged to roll out the links of survey to their contacts.

Data collection tool

A self-prepared questionnaire was used for the study. The questionnaire was expert validated, and further reliability was also studied. Following this, the questionnaire was converted to Google forms for data collection. The questionnaire had 35 questions dividing into following sections:

  1. Demographic and work details: five multiple-choice questions (MCQs)
  2. Knowledge of RTs (awareness of COVID-19, mode of transmission, precautionary measures, diagnosis, and clinical presentation of the disease) ten MCQ with one right answer
  3. Confidence level of RTs in performing desired clinical skills (delivery of supplementary oxygen, setting up of invasive and non-invasive ventilation, the procedure of intubation and extubation, skills required for routine management of a ventilator patient, and assisting in emergency procedures): ten questions with five-point Likert score (1 – not at all, 2 – not really, 3 – undecided, 4 – somewhat, and 5 – very much)
  4. Perception of RTs role in COVID-19 disease: five questions with a numeric score of 1 = yes and 0 = no.


Psychological impact of COVID-19 on RTs: five questions with a five-point Likert score (1 – not at all, 2 – not really, 3 – undecided, 4 – somewhat likely, and 5 – very much likely).

Study variables

  • Independent variables: Demographic data such as gender, age, academic qualifications, and geographic location
  • Dependent variables: Knowledge, confidence levels, and perceptions toward COVID-19.


Operational definitions

Knowledge on COVID-19

The RT's total knowledge score in COVID-19 was between 0 and 10 (0 = no correct answer and 10 all correct answers). Scores were graded as follows: <5 – poor knowledge, 5–7 – moderate knowledge, and 8–10 – good knowledge.

Confidence levels in performing skills required in COVID-19 care

There were ten questions with a five-point Likert scale. The minimum scores were 10 (not at all confident in any skill) and maximum score was 50 (very much confident in all the skills). A mean score >40 (answering for somewhat or very much) was considered as higher confidence in performing the skills requiring in COVID-19 care.

Respiratory therapist's perception on COVID-19 and psychological impact of COVID-19

The questions to assess the perception of RTs role in treating a COVID-19 were based on five questions with numeric score of 1 = yes and 0 = no. The minimum and maximum scores were 0 (answering no to all questions) to 5 (answering yes to all questions). Mean score >4 considered the role of RT as important in managing COVID-19 cases.

Psychological impact of COVID-19 on respiratory therapists

It consisted five questions using five-point Likert score. The mean score >15 (answering for undecided/regularly, somewhat/usually, and very much/always) was considered as a negative psychological impact on RT.

Statistical analysis

Continuous variables were reported in mean and standard deviation. Categorical variables (area of work, year of experience gender, qualification, region, and involved in COVID unit) were reported in n (%). The Likert scale scoring was expressed in n (%). Reliability of the questionnaire was tested using Cronbach's Alpha. Validity was assessed through correlation. The association between independent variables and dependent variables was assessed using the multivariate analysis. One-way ANOVA was done to study the difference between knowledge, confidence, and perception between genders Statistical software SPSS (IBM Corp. Released 2015. IBM SPSS Statistics for Windows, Version 23.0. Armonk, NY: IBM Corp) was used for the analysis. P < 0.05 was considered statistically significant.


  Results Top


This was a cross-sectional, questionnaire-based study and a total of 68 RTs responded, yielding a response rate of 70.8%. Of them, more than half were females (55.8%), qualified to bachelor's degree in respiratory therapy (85%), working in ICU set up (93%), had <2 years of experience (69%), and majority of them were working in COVID-19 unit (87%). The demographic and work details of the participants are summarized in [Table 1].

Validity was assessed through correlation. All the three sections of the questions had good correlation, and there was a significant difference between the questions. [Table 4]a, [Table 4]b, [Table 4]c shows the correlation of questions for each domain. Reliability test (Cronbach's alpha α) showed α of 0.65 which is an acceptable reliability. Multivariate analysis showed that there was a significant difference between the psychological component and the education level of the participants. There was a difference between the perceptions by the bachelor's/master's graduate versus the PG diploma holder. One-way ANOVA showed no difference in knowledge, confidence, and perception of RTs between males and females.

  Discussion Top


As per our knowledge, this is the first study on RTs, assessing the knowledge, confidence, and perception on COVID-19 pandemic.

A total of 68 RTs responded to the questions. Three domains of RTs were assessed. The Knowledge domain showed that 42 (62%) of RTs had good knowledge, 25 (37%) of them had moderate to good knowledge about COVID-19. This was consistent with studies conducted on other health-care workers (nurses, pharmacists, and physicians) concerning knowledge about COVID-19 pandemic.[3],[4],[5] We were unable to compare the knowledge level among RTs, as no previous studies were conducted. Contrary to this, a study conducted globally by Bhagavathula et al. found that healthcare workers had insufficient knowledge on COVID-19.[6] This could be because the study was conducted at the beginning of the pandemic, and our study was conducted during the peak phase of the pandemic.

Our study found a higher confidence level 65 (96%) among RTs in performing clinical skills required for managing a COVID-19 case. Skills such as setting up ventilator and airway adjuncts, preparing and assisting intubation, performing closed suction had a score of more than 80% suggesting higher confidence in these areas. These findings confirm that most RTs in India have adequate training in independently managing the respiratory therapy skills required for care of COVID-19 in ICU. A cross sectional survey done in Japan[7] and found that the confidence level in the management of COVID-19 among HCPs (doctors and other health-care workers) were very low, concluding that it could be due to the lack of latest information and absence of knowledge on how to protect themselves and their patients.

Perception of RTs toward the importance of their role in managing COVID-19 cases was found to be 98.5% (67) which indicated that almost all the study participants felt that RTs are an integral part of COVID-19 management. We also found that 98.5% (67) of study participants had an overall negative psychological impression toward the pandemic. The study participants were concerned about their family members getting infected by them and accounted for 80% mean score. Comparatively, the study participants had higher confidence in not being infected after using personal protective equipment. A systematic review found that anxiety, depression, and insomnia prevalence among health professionals during the COVID-19 outbreak were 23.2%, 22.8%, and 38.9%, respectively.[8] Similar results were found in studies that assessed the psychological impact on other health-care workers in SARS CoV 2 infection.[9],[10] A study done among health-care workers in Uganda had advised continued education among the health-care workers to improve the knowledge and avert the negative attitudes and promote preventive and therapeutic practices.[11]

Reliability of the questionnaire that was developed by the researcher was tested and was found to be in acceptable reliability range. Cronbach's alpha is considered one of the most important tests where the test construction is involved.[12] Alpha values are described as follows. Excellent (0.93–0.94), strong (0.91–0.93), reliable (0.84–0.90), robust (0.81), fairly high (0.76–0.95), high (0.73–0.95), good (0.71–0.91), relatively high (0.70–0.77), slightly low (0.68), reasonable (0.67–0.87), adequate (0.64–0.85), moderate (0.61–0.65), satisfactory (0.58–0.97), acceptable (0.45–0.98), sufficient (0.45–0.96), not satisfactory (0.4–0.55), and low (0.11).[13]

Validity is the degree to which a test measures what it is intended to measure.[14] This is to measure basically the practical usefulness or to see how meaningful is the questionnaire.[15],[16] Validity of the questionnaire was good and could be used for further studies in the similar population. A larger study with the same questionnaire will give more insights to the validity and reliability of current questionnaire.

Limitations

This is a questionnaire-based survey and the responses depend on the participant's honesty and can be subjected to recall bias. Due to small sample size, statistical analysis for correlation could not be performed.


  Conclusions Top


RTs have excellent clinical skills required during the management of COVID-19 patients in a high dependency or critical care unit. Being an integral part of a critical care unit, it is essential to assess any pandemic's knowledge and perception.

Acknowledgment

We would like to acknowledge and thank all RTs who have participated in the study across India and has helped in circulation the questionnaire.
