Lived Experience of Nurses in COVID-19 Units - A Phenomenological Study from Eastern India

Introduction: Nurses are the frontline workers who had to play multiple functions like in acute care, community, etc. but, it was stated that COVID-19 has caused immense trauma to nurses globally. Methods: A descriptive phenomenological study to explore the lived experience of nurses working in COVID-19 units was conducted among nine senior nursing officers recruited by purposive homogenous sampling and interviewed with an open-ended interview guide by ensuring data saturation. COREQ guideline were adopted for this qualitative study. Results: Qualitative data were analysed using Giorgi’s framework, and themes and sub-themes were derived. The major themes that emerged in the present study were "Reactions and preparation", "Feelings and satisfaction in active duty", "Role of a helping hand", "Working experience in PPE", and "Pandemic and socialization". Each theme had further sub-themes to classify the verbatims. Conclusion: Most of the nurses had anxiety and prepared themselves to play with fire, had unrealistic hope, and mixed emotions, kept their family away and intentionally concealed information to reduce family’s fear, were satisfied with training and preparation, and had unpleasant experiences with PPE, had to restrict their social activities and felt social stigma. It also concludes with the recommendation that warrants the need to improve their professional quality of life and working conditions by safeguarding nurses’ physical and mental health.


Introduction
India may not have been one of the first countries to get affected by COVID-19, but eventually, it was hit severely in the late 2020s to the early months of 2021. 1 In India, the first case of SARS-CoV 2 infection was reported in a medical student who returned from Wuhan, in the southern state of Kerala on January 27, 2020. 1 Even from the early days of the pandemic, India remained to have been a very high-risk country, due to various reasons, high population density, high prevalence of diabetes, 2 and hypertension, 3 and a huge proportion of children with stunting, malnutrition, and other communicable diseases. 4 During the first wave of the pandemic, the International Council of Nurses (ICN) reported a rise of 60% to 80% in mental health issues among nurses around the world. 5 In a profession where the shortage of manpower is already profound (up to 10 million short), and an additional loss of 10-15% due to absenteeism or leave was evident as an impact of COVID-19, the deficit in the workforce was even more devastating as it eventually impacted the health system globally. 5 This was also evident in an online survey conducted among 1080 undergraduate nursing students of Fujian Medical University, China, which enquired regarding perceived turnover intention and its associated factors. The results showed that the majority of nursing students had a moderate level of fear, such as fear of infecting family, and fear of death and many students reported severe mental disturbances. It was also seen that students of older age and with better grades showed more fear than others. The significance of the study was seen when almost 50% of the students reported that they would not choose a nursing course or will not pursue nursing practice in the future. These findings showed the alarming potential loss of almost half of the prospective nurses from entering the nursing workforce. This warrants the need for immediate action by mental health agencies thereby ensuring mental health services and also dissemination of updated information on COVID-19 for addressing the fear and anxiety among nursing students. 6 Nurses had to face various challenges as the frontline warrior in the recklessly spreading COVID-19. Nurses' work is based on sound scientific inquiry and evidence, as the COVID-19 was presented with none of those, and work-related anxiety and psychological issues were out of control. 7 Nurses had to be educated on the proper use of protective gear and COVID-19 infection control practices for effective control of the pandemic. 8 Moreover, this protective equipment was inadequate throughout the world, as no health system was equipped for a pandemic of such magnitude. This led to multiple exposures and illnesses leading to continued absence in a health profession already scarce in manpower. 9 Limited and insufficient manpower in the times of the COVID-19 pandemic, added to a more dangerous situation as the nurses were required to overwork, and nurses who were without experience in working with infectious diseases had to play the part. 10 Moreover, the demanding situation of this pandemic along with these challenges at the forefront resulted in the outbreak of uncertainties, distress, and anxiety among the nurses. 11 The rapidly evolving protocols and emerging new evidence now and then were another significant issue faced by the nursing workforce. There was an evident change of focus from individual care to public health, along with changing styles of leadership, and changing working hours which were all contributing stressors for nurses who were constantly adapting to the new environment. 12,13 All these challenges combined with the barriers to maintaining the optimal standards of care due to the fear of contracting the infection predisposed the nurses to a significant decrease in the professional quality of care. 14,15 Decreased professional quality of life and impaired moral distress among nurses would often distance them from bedside care. 16 A cross-sectional, correlational survey to explore the factors associated with moral distress among nurses after the 2020 pandemic attack in two academic centers of the north-eastern USA, showed a higher frequency of COVID-specific morally distressing situations daily. Distress-producing events were identified as a risk of transmission, caring for clients without their families, and the death of clients in absence of their families. 17 Poor communication from leaders has also been found to be anxiety-provoking. This was also evident from a study done during the 2002-04 SARS attack in the USA where the key elements in managing fear and anxiety were trust and transparency among the health workers. 18 With these circumstances, the healthcare workers, especially nurses along with lots of physical, psychological, social, professional, and even spiritual challenges, are on the frontline to tackle this pandemic of epic proportions.
In its basic form, phenomenology attempts to study subjective phenomena in the belief that critical truths about reality are grounded in people's lived experiences. Although phenomenology seeks to be scientific, it does not attempt to study consciousness from the perspective of clinical psychology or neurology. Instead, it seeks through systematic reflection to determine the essential properties and structure of experience. 19 Nurses were deeply impacted in many aspects by the sudden exposure to the pandemic with an already profound shortage of nurses was severely affected by the physical and mental health and absenteeism during the pandemic. Nurses' quality of life was quite affected during the pandemic but the good mental preparation and resilience of nurses might help them to overcome the issues. Thus, this Phenomenological study aims to explore the lived experience of nurses, from the moment they realised that they are at the forefront of fighting this unprecedented pandemic.

Materials and Methods
A Qualitative research approach with a descriptive phenomenological design was adopted to explore the lived experience of the nurses working at a dedicated COVID-19 Hospital in Eastern India (All India Institute of Medical Sciences (AIIMS), Patna). Formal administrative approval was obtained from Institutional Ethics Committee, AIIMS, Patna (AIIMS/Pat/IEC/2020/473). The study was carried out by the guidelines laid by the Indian Council of Medical Research (ICMR) (2017). 20 The Report was prepared and presented as per the Consolidated Criteria for Reporting Qualitative Research (COREQ) guideline. 21 A total of 9 Senior Nursing Officers were recruited for the study based on the purposive homogenous sampling technique. Among the various purposive sampling techniques used in qualitative studies proposed by Patton, Teddlie, and Tashakkori as reported by Polit and Beck,19 in the present study, homogenous sampling was considered which is a type of sampling for representativeness in the qualitative study and meant the opposite for maximum variation sampling which deliberately reduces maximum variation and permits a more focused inquiry. 19 Since homogenous sampling was used, the sample size comprised 9 Senior Nursing Officers working in COVID-19 units at a dedicated COVID-19 hospital. All the participants had similar qualifications, type of service, and designation. The Open-ended interview guide was used to explore their lived experience in COVID-19 units. Data enrichment was achieved after interviewing 8 study participants with the initial analysis but to ensure that the enrichment had been achieved one more participant was recruited for the study to explore the possibility of any new information. Written informed consent were obtained. All the participants consented to the interview and none of them refused or dropped out of the study. Initially, the tool and interview were pilot tested with one participant before proceeding with a final set of study participants. Before starting the data collection, the researcher conducted preinterview interaction sessions for the establishment of rapport with participants to ensure prolonged engagement in the field. Study participants were provided with a participant information sheet containing researchers' details and study goals, assured of confidentiality and anonymity, and based on which informed consent was obtained from them for an interview and audio recording. Sample characteristics data were collected by self-report (self-administered questionnaire) which was followed by an open-ended interview as per the interview guide. Participants were asked to have a look at items of the interview guide before proceeding with the interview to avoid any misunderstanding, to understand the nature of the questions, and what the items of the interview guide are exactly meant to explore. The main focus of the interview guide was on the overall lived experience of nurses in COVID-19 units. There were six items in the interview guide such as 1) What were their reactions; when they realized that they were being posted to the COVID-19 unit (Probs-Emotional and work aspects), 2) What were their feelings while on active duty (Probs-Positive and negative feelings), 3) Experience about support from family and friends (Probs-Psychological conditions of self, family and friends), 4) Preparedness and support from the employer (Probs-Training, protocol and resources), 5) Working in a personal protective equipment (PPE) (Probs-Restrictions, needs, risks and complaints), and 6) Changes in personal, family, social and other areas of life (Probs-Social activities, relationship issues). Data collection alone was phased for the duration of three months from July to September 2020. Each interview lasted for 20-45 minutes and the single investigator conducted all the interviews to ensure data saturation and to maintain a reflexive journal. The interviewer was a male (PS) who had a qualification of Master's degree in the field of psychiatric nursing and had previous experience in conducting qualitative studies on the psychological phenomenon. Field notes were made immediately after the interview. The duration of the interview and probs used varied from one participant to another. Additional probs such as 'hmmm…' , ' Anything else' , 'Would you like to add' , 'You can tell me later if you wish' , 'Would you like to talk more' , 'Would you like to elaborate more' and so on also were used. All the interviews were face-to-face and one-to-one interviews, audio recorded, and conducted in a dedicated room at the workplace, which was feasible for the participants at their convenient time. All the interviews were one time and the no-repeat interview was conducted. Collected data were coded, transcribed, and translated by three investigators (KM, KJ, AJ) other than the one who was involved in interviewing the participants. Firstly, the audio recordings were transcribed in original, cross-checked for their correctness, and then translated verbatim into English (participant-wise and item-wise as well). Then the translated data was checked for originality by two language experts qualified with master's degrees in English and Hindi literature respectively, which were then used for the generation of themes and sub-themes to proceed with the narrative analysis.
According to Polit and Beck, 'Reliability refers to the accuracy of measurement' , is the concept used by positivists that have been termed by the constructivist as 'Trustworthiness' . 19 The Rigor/Trustworthiness/Quality enhancement strategies of the present study data were ensured by applying Lincoln and Guba's model suggested five criteria for developing the trustworthiness of a qualitative inquiry including Credibility, Dependability, Confirmability, Transferability, and Authenticity. 19 In the present qualitative inquiry, the rigor was ensured by the following strategies: 1) Credibility by reflexivity, prolonged engagement, and peer debriefing. 2) Dependability by inquiry or external audits. 3) Confirmability by investigator triangulation and inquiry audits. 4) Transferability by saturation, thick description, and documentation of quality enhancement efforts. 5) Authenticity by similar other credibility strategies from the data generation phase to the dissemination.
Data analysis for the qualitative data in this descriptive phenomenology was guided by Giorgi's framework. 22 Giorgi's method of analysis aimed to uncover the meaning of a phenomenon as experienced by a human through the identification of essential themes, the basic outcomes of this model are the description of the meaning of an experience often through the identification of useful themes. [22][23][24] Themes are the way of describing large quantities of data in a condensed manner and it is a recurring regularity emerging from an analysis of qualitative data. 19 The manual, non-software thematic analysis was considered. Based on the concept of the thematic analysis approach suggested by Giorgi's method of phenomenological analysis, it was carried out in the following steps; 1. Red the entire set of protocols or translated verbatims to get a sense of the whole: Both participants and item-wise protocols and translated verbatims were read to understand the completeness of their lived experiences. 2. Discriminated units from participants' description of lived experiences in COVID-19 units: Meaning units were derived from participants' description of the phenomenon, and a total of thirty meaning units were identified initially and then ended up in twentyfour. 3. Articulated the psychological insights in each of the meaning units: All the meaning units were analysed for deep psychological insights before clustering them into themes. 4. Synthesized all of the transformed meaning units into a consistent statement regarding participants' experiences: All the derived meaning units were clustered as per the psychological meanings into various themes. A total of six themes were formed by clustering the identified twenty-four meaning units. The themes and sub-themes that emerged from the analysis of qualitative data based on the above-mentioned steps are depicted in Figure 1.

Results
Frequency and percentage distribution, mean and standard deviation with regard to socio-demographic profile of the study participants are shown in Table 1.
Quality enhancement strategies used in the study are shown in Table 2.
Themes and sub-themes that emerged from Giorgi's method of phenomenological analysis (see Figure 1) are elaborated as follows:

A. Reactions and Preparation
The sub-themes that emerged under this theme include fear and anxiety, accepting responsibility, mental preparation, unrealistic hope, and physical and mental reactions.

Fear and anxiety:
In this regard, some of the participants verbalized that: "Of course, fear was there, with people… with everybody fear was there, like, at the time of sample collection, earlier a team of doctors was collecting oropharyngeal or nasopharyngeal swab samples, suddenly we came to know that nurses are supposed to do the sample collection. " (P1) "First time, I was posted in the non-COVID ward... so, a phone call came to me that I have to do my duty there (COVID unit)… and then there was a little anxiety. " (P4) In contrast: "First time, I was very happy. It was happy, in the sense, because we are going to a new environment and we will be  The majority of the participants verbalized that they had fear and anxiety as their major concern at the beginning and attributed it to unawareness and lack of knowledge about the illness, wearing PPE during work, and sampling procedures. 2. Accepting responsibility: In this regard, some of the participants verbalized that "Yes, Of course, little stress was there, that by chance if I get… but it was also there that if I don't do my duty then somebody else would have to do and then it would happen to him. " (P1) "First time when you are working you had to wear the PPE and who knows something would happen to you, like that it was both emotional as well as physical…but once patients started coming in, then it became very busy… then after that nothing that sort thinking came to our mind. We were adjusted to that environment. " (P4) The majority of the participants verbalized their sense of responsibility towards the job at the beginning itself despite facing anxiety associated with COVID-19.

Mental preparation:
In this regard, some of the participants verbalized that: "Earlier when… when we knew this pandemic is here and it is going on everywhere, we certainly knew that cases would come to our institute as well, so our mind was already prepared for this thing. " (P1) "When this was reported initially in China, that day itself my husband had told this will come to India and there will be lockdown here. My husband told me on the first day, see it will happen here and there will be a lockdown here as well and cases will also increase here like it is in China. So, I was mentally prepared from the beginning. " (P2) "Firstly, we know that COVID-19 is a pandemic situation, came to India, recently…late in comparison to China, I got to know some information regarding the COVID-19 that was updated in W.H.O. website, so I had some idea about the COVID-19. " (P7) Most of the participants verbalized that they had some information, prediction, or certainty that it would be striking India sooner or later and anticipated and prepared themselves mentally to play with the fire. 4. Unrealistic hope: In this regard, some of the participants verbalized that: "All the time, when I enter the hospital, I feel very much distressed, that when this will get over… and hopefully, it will take 3-6 months and we are expecting and praying to God, to get a vaccine. " "And every day, I pray to God and I am a believer… I do pray for my patients also, who are Most of the participants verbalized their physical and psychogenic tiredness during their initial period of postings in COVID-19 duty to which they might have adjusted later on but the concern was heaviness, toughness, and tiredness both physically and mentally.

B. Feelings and Satisfaction in Active Duty
The sub-themes that emerged under this theme include positive and negative feelings and satisfaction with work. Most of the participants felt the duty hectic and frequent changes in the posting area and inadequate team spirit made them feel unsatisfactory but few participants felt satisfied with the work that has been done.

C. Role of a Helping Hand
The sub-themes that emerged under this theme include family stay vs non-stay, family's fear, support from family and friends, support from employer, training and preparation, and supplies and resources. Few participants expressed that staying with family is comfortable, at least they can get hygienic food and remain healthy during the pandemic. Whereas few of the participants felt that staying with family is a mental turmoil as they can transmit infection quickly to significant others and that would predispose them to more distress than before.

Family's fear:
In this regard, some of the participants verbalized that: "We are living very far from our home, I mean, here only wife and children are staying and parents are in the home, very far from here. I belong to XX…so, parents are like that, they don't understand about the medical line as their profession is different…so, usually they are more scared". "They also say leave all this now, leave it, leave it…but leaving is not possible as it is our work, so I cannot leave this. " (P1) "We didn't tell our father and mother that I am working here in COVID duty because they would get tensed and anxious… So, we did not tell them. " (P4) "First of all, I didn't inform that I started working in COVID area. I didn't inform my family because they may be stressed, they're also 65 above and they will be worried. " (P7) The majority of the participants verbalized that intentional concealment of information about their posting in the COVID-19 unit was their strategy to prevent the exaggeration of fear among their family members. Most of the participants expressed that employer had supported them throughout by whatever possible means but few of them felt that work and duty schedule, in the beginning, was not so consistent and required to do a lot of paperwork. 5. Training and preparation: In this regard, some of the participants verbalized that: "Training is alright. In our nursing college itself one training on stress management happened, that is still going on. That I attended, and received a little bit of support. " (P2) "Our hospital has been very good that, during the COVID, and even before the COVID good training was given to everybody…and prepared us mentally as well as physically. " (P4) Most of the participants conveyed that they received adequate and satisfactory provision of supplies and resources throughout but at the beginning few of them felt that there were issues in manpower arrangement and had bad experiences, especially with the quality of PPE provided for them during COVID-19 duty.

D. Working Experience in PPE
The sub-themes that emerged under this theme include restriction in meeting needs with PPE, physical complaints with PPE, Goggle fogging, and communication hindrances in PPE, unpleasantness, and doffing the different experience.

Restriction in meeting the needs with PPE:
In this regard, some of the participants verbalized that: "We cannot drink water properly…we are not drinking water. " (P1) "We will be feeling thirsty…and elimination needs are also very much disturbed while wearing a PPE…what we can do, we can't help it. " (P3) "Once we put on the PPE, we can't drink water, we can't use the washroom, we can't even touch our face, and we can't even wash our face…" (P5) Highlight: "So, in the beginning, when I started my duty, my concept was to use a diaper, but later dropped this idea due to this heat using diaper would also be an irritation… it's an added irritation…Because of that, I started drinking less water so I will not urinate frequently. " (P2) Outlier: "We drink sufficient water from home and for next 6 hours water is not needed. We are adjusting and we never feel to eat or drink here (hospital), and we eat sufficiently before coming here" (P4) Most of the participants experienced the restriction in intake and output while wearing PPE and few of them suggested compensatory practices to face the difficulties.

Physical complaints with PPE:
In this regard, some of the participants verbalized that: "The quality of the PPE that was provided, was different each time, and working in those PPE was very difficult because the material it was made of irritates the skin a lot. As there is no intake of water the urine is mostly yellow…and temperature of the body feels very high in PPE" (P1) "Before donning itself, we are sweating, the temperature is so high outside, on top of that we are not using the AC, and when you start to drink less water before and throughout the complete duty, you will get urine infection, on top of that sometimes it feels like dizziness also. " (P2) "Then…we will talk particularly about the bad quality PPE, we get, it was a suffocating experience. " (P3) "We get so much sweating after wearing PPE. " (P3, P4, P5, P7, P8) "There has been a lot of irritation in the body, skin problems, rashes, loose motion, and dehydration all these things were also felt. " (P9) Almost all the participants had physical discomforts such as sweating, skin irritation and skin rashes, hyperthermia, and change in urine color with the use of PPE. 3. Goggle fogging: In this regard, some of the participants verbalized that: "The goggle we are getting here, fogs easily and it is very much so… and it is difficult to see…because of wearing masks, these "wrappers" completely go inside these goggles, and we cannot see. About 90% of staff wear their goggles above their forehead…these people do not wear them, because of fog. What work will you do, if they cannot see anything?" (P1) "If you are putting on goggles, we can't see anything… and the moisture that accumulates inside the goggles feels like rain. We can't see anything and here the thing is for each and everything, we have to depend on the system (computer)…so, once we put on this and sit in front of the system, it is white, nothing extra. " (P5) "While working with the goggles, we cannot see anything after one hour, it's nothing but only mist comes. Sometimes we have to remove it for cannulation or any other procedures…and when you remove the goggles you understand that there is a breach. " (P7) Most of the participants felt that wearing goggles was meant for protection but fogging and moisture attributed to it caused interference in vision and nursing care and few participants felt working in front of the system (computer) for data entry also got hampered by using goggles.

Communication hindrances in PPE:
In this regard, some of the participants verbalized that: "If anyone saying something behind us, we can't hear, we have to go nearby them…even doctors, if they are calling, sometimes we never hear. We never hear whether anyone is calling or is he telling us something. Even the patients, if they are calling us, we just can't hear because it (ear) is already numb and at the same time, after covering all the parts, it is so horrible to do duty in PPE. " (P5) "When we wear our PPE, our ears are blocked and when we talk lightly, people cannot hear you, so we have developed a habit of talking loudly. So, after talking loudly, for us personally also it started happening that I would yell out everything. " (P9) Almost all the participants had issues with communication while wearing PPE. They were not able to hear or people could not hear them or even patients lost interest in talking and few of the participants felt that they started speaking loudly even after removing PPE. 5. Unpleasantness: In this regard, some of the participants verbalized that: "We cannot hear, we cannot see. It was the first-time using PPE, it was a suffocating experience. I don't feel it is a good experience to wear PPE. " (P3) "In night duty, when we feel to drink water, we just cannot as we could not change the PPE. Almost after 6-7 hours only we can change, and that is when we would drink water…and night duty is a bit too long in PPE, so that is a bit uncomfortable. " (P4) "I could say, it is horrible, to do duty… to do work in a PPE, it's horrible, we are not at all comfortable, we just can't do anything. So, comfort level, I could say, it is zero" (P5) "I am, being a female, if anybody gets periods and all, it is very difficult. " (P8) Highlight: "If someone tells me, on this date, that do you wish to work without PPE or with PPE… maybe I am so tired, I will work without PPE and tell that I would work without PPE even if I get corona, it doesn't make any difference. PPE… that is now mandatory that's why people are wearing, otherwise, we are so fed-up wearing PPE. That is all!!" (P2) Almost all the participants had an unpleasant and horrible experience but, a few of the participants expressed that though it protects us if they were given the option then they would choose to work without PPE. They were ready to face risk rather than using it continuously and few of them questioned why did they get into this profession.

E. Pandemic and Socialization
The sub-themes that emerged under this theme include restricted social activities, communication and relationship issues, cautious and changed lifestyle, positive and negative mindset in COVID, and the Social stigma. Almost most of the participants had a positive mindset to overcome COVID-19 and about their future by exploring their confidence to live through pandemics again but few felt that they stopped thinking about their future now. 5. The Social stigma: In this regard, some of the participants verbalized that: "…and one more thing is also there, those Nursing officers and Senior nursing Officers, wherever they are living or residing on rent have faced problems…I mean, some people are there, they are showing one type of social stigma towards them that they were medical professionals. " (P1) "And the social stigma… if anyone is identified as a nurse or doing duty in a positive area, that becomes a barrier. So, he will be isolated from society. When I was buying things for my room, for myself, they asked, 'if there is anyone positive in your block or in your flat'… so, if I am saying yes, that will become a problem, for me also. So, I do… I hide the fact, I said no…" (P5) Most of the participants expressed the social stigma because of being a health care workers at their residence and they had to hide their known COVID-19 status from others to avoid experiencing discrimination.

Discussion
This qualitative study explored the lived experiences of nurses working in COVID-19 units of a dedicated COVID-19 Hospital in eastern India. Researchers have identified five main themes depicting the nurses' experiences related to nursing care activities during the COVID-19 pandemic. Overall, the findings of the study revealed that the majority of the nurses experienced adversities, especially in the initial days of the pandemic, and gradually developed preparedness for providing better patient care in addition to a wide range of experiences.
In this study, a major concern for nurses at the beginning was fear and anxiety which were attributed to unawareness and lack of knowledge about the illness and wearing PPE during work. This negative emotion of fear and anxiety could negatively influence the physical and psychological well-being of the frontline nurses. 25,26 It was consistent with the findings of the study conducted that a lack of appropriate knowledge and training in emergency disaster and rescue can predispose the nurse to increased fear. 27,28 It was also consistent with the findings of the other studies that fear was related to the contagious nature of the virus and the risk for self-infection 29 and fear and anxiety can hamper the quality of patient care. 30 Nurses working in COVID-19 units were showing readiness and willingness to provide care despite being aware of the risk of getting infected. This was supported by the findings of the study in which nurses were willing to provide care to the patients with COVID-19. 31 Nurses felt that the care to be given is a part of their job and their role in the need of this hour is also vital, which was consistent with other studies conducted and reported similar findings. 29,32 Most of the nurses received adequate support from their employer, but some of them expressed their displeasure towards the inconsistency in work and duty schedule in the beginning and issues in the manpower requirement which is in contrast with the study conducted where nurses were able to work together with minimal conflicts despite knowing the other team members for less than six months. 33 Nursing leaders play a key role in recognizing and developing the sense of belongingness and team spirit among nurses. 29 In the present study, long working hours with PPE resulted in various physical discomforts such as sweating, skin irritation, and skin rashes; visual disturbances such as goggle fogging, suffocation, dizziness, and unpleasantness among nurses. These findings were consistent with the study conducted in which nurses reported physical discomfort related to PPE. 34 Several other studies also reported wearing PPE resulted in visual disturbances and dermatitis. 29,35,36 In contrast to the present study findings, some physical symptoms such as chest pain, anoxia, and facial pressure injuries were also reported. 37,38 Nurses shared their experiences regarding the bad quality of PPE which was consistent with findings of a study conducted in which recommendation was given for maintaining the consistency in the quality of PPEs. 29,36 In the present study, nurses who were living with their families believed that they might be the source of infection to their loved ones and wanted to keep them isolated. The study results were consistent with the other study conducted where nurses intentionally deprived themselves of their families to prevent any physical contact during COVID-19 duties. 32,39 Another interesting finding of the present study is the presence of unrealistic hope (both spiritually and from the medical profession regarding the termination of this pandemic), a mix of both positive and negative emotions among the nurses, intentional concealment of information from the family members to reduce the fear of their family members, receipt of adequate support from the family and friends to deal with this pandemic, communication hindrances while caring for the patient working with PPEs, restricted social activities due to the risk of infection and social stigma felt by the nurses from their living places. Altogether, the pandemic has changed the lifestyle of nurses who are working in COVID-19 units.
The present phenomenological study explored the lived experiences of nurses working in COVID-19 units of a dedicated COVID-19 Hospital in Eastern India. About the limitations of the study, it is limited in scope due to the interview of 9 nurses in a single dedicated COVID-19 care hospital which might affect the generalization but the homogenous purposive sampling could help in focusing its generalization on the specific target group. As the interview was conducted a few months after the outbreak of the pandemic and phased for three months, responses might have varied during the outbreak and later period.

Conclusion
The present study concluded with regard to the lived experiences of nurses in COVID-19 units that most of the nurses had anxiety and prepared themselves to play with fire, had unrealistic hope, mixed emotions, kept their families away, and intentionally concealed the information to reduce family's fear, they were satisfied with training and preparation and had an unpleasant experience with PPE, had to restrict their social activities and experienced social stigma. Further, it concludes with the recommendation that, it is well understood that the amount of time spent in caring for patients with COVID-19 by nurses is the greatest in comparison to any other health care professional which makes nurses the most significant frontline warriors. Hence, adequate measures should be taken by the government and employers to improve their professional quality of life and working conditions by safeguarding the physical and mental health of these frontline warriors i.e. nurses.
