Registered nurses’ experiences of providing respiratory care in relation to hospital- acquired pneumonia at in-patient stroke units: a qualitative descriptive study
BMC Nursing volume 19, Article number: 124 (2020)
This study aimed to describe registered nurses’ (RNs) experiences of providing respiratory care in relation to hospital acquired pneumonia (HAP), specifically among patients with acute stroke being cared for at in-patient stroke units.
One of the most common and serious respiratory complications associated with acute stroke is HAP. Respiratory care is among the fundamentals of patient care, and thus competency in this field is expected as part of nursing training. However, there is a paucity of literature detailing RNs’ experiences with respiratory care in relation to HAP, specifically among patients with acute stroke, in the context of stroke units. As such, there is a need to expand the knowledge base relating to respiratory care focusing on HAP, to assist with evidence-based nursing.
A qualitative descriptive study.
Eleven RNs working in four different acute stroke units in Southern Sweden participated in the current study. The data were collected through semi-structured interviews, and the transcribed interviews were analysed using inductive content analysis.
Three overarching categories were identified: (1), awareness of risk assessments and risk factors for HAP (2) targeting HAP through multiple nursing care actions, and (3) challenges in providing respiratory care to patients in risk of HAP. These reflected the similarities and differences in the experiences that RNs had with providing respiratory care in relation to HAP among in-patients with acute stroke.
The findings from this study suggest that the RNs experience organisational challenges in providing respiratory care for HAP among patients with acute stroke. Respiratory care plays a vital role in the identification and prevention of HAP, but our findings imply that RNs’ knowledge needs to be improved, the fundamentals of nursing care need to be prioritised, and evidence-based guidelines must be implemented. RNs would also benefit from further education and support, in order to lead point-of-care nursing in multidisciplinary stroke teams.
One of the most common and serious respiratory complications associated with acute stroke is hospital acquired pneumonia (HAP). Several terms are used in the literature to refer to pneumonia following an acute stroke. In this study, the term hospital acquired pneumonia (HAP) will be used, per recommendation from the European Stroke Organisation, (ESO) . The ESO defines HAP as an acute lower respiratory tract infection, acquired after a minimum of 48 h of hospitalisation, and not having been incubating at the time of admission . The incidence of HAP in stroke units is estimated to be between 39 and 44% . Among stroke patients, the mortality rate from pneumonia is higher than that for other care-related infections, such as urinary tract infections. Recovery from an acute stroke has also been found to be negatively impacted if, post stroke, the patient acquires HAP as it increases the likelihood of dependency  and the time in care by up to 7.5 days . This is significant, as around 15 million people worldwide suffer from stroke annually , underscoring the importance of improving knowledge relating to respiratory nursing care, especially to prevent and target complications such as pneumonia among this substantial group of patients.
Nowadays, the majority of RNs working with stroke patients are doing so at an organised in-patient unit (stroke unit) which is acknowledged as an evidence-based model of patient management . At these units’ the RNs are part of a co-ordinated teamwork, which requires that a certain percentage of the team has completed specialist stroke training (RNs included), and care is expected to be based on evidence, in addition to safety standards . Within the team, RNs are the largest professional group , and are described as those with the most prolonged contact with patients, i.e., 24 h a day . As a result, RNs are expected to possess the knowledge and skills needed to provide the patients with excellent care at these units. The role of an RN is to assess, diagnose, intervene, and evaluate the patient’s fundamental personal needs . Richards and Borglin  point out that one of the crucial elements of nursing, should be that they are focused on the patients’ essential personal needs, including respiration, mobility, cleanliness, and nutrition. These needs, or fundamentals of care, have been rearticulated by Kitson and colleagues , to link the psychosocial, physical, and relational dimensions of the nursing care encounter. Respiratory care includes the assessment of breathing (respiration), to identify problems and complications early on, and is a vital part of the fundamentals of care , and thus competency in this field is a standard requirement of RNs. Among acute stroke patients, it is particularly important that their RNs are able to identify and address respiratory complications. Specifically, by identifying patients at risk of respiratory problems, whilst simultaneously delivering relevant nursing care to those who have already developed such problems, RNs help to prevent further complications from developing, including pneumonia, which is one of the leading causes of death for stroke patients  However, published explorations of what actually constitutes respiratory nursing care in practise, are sparse, especially in the context of stroke units. Additionally, how nursing care in such dedicated units, and as a part of a co-ordinated teamwork influences the delivery of nursing care is neither well described. Nonetheless, it is evident that being cared for at an organised in-patient stroke unit are beneficial for this group of patient’s rehabilitation and recovery. In a recent Cochrane review, it was concluded that one-year post stroke, those patients receiving care at stroke units were more likely than those receiving care outside such units to be alive, be independent, and live at home, i.e., to recover . Working in interprofessional teams to certify patient safety and quality of care, is one of the six core competencies required of RNs to meet health care standards , and is a realistic approach to improving nursing care targeting HAP. Indeed, skilled nursing care has been proposed as an essential component of stroke units .
Despite the aforementioned, there is a lack of literature relating to RNs’ experiences of respiratory care focussing on HAP in patients with acute stroke, specifically in the context of stroke units. However, one systematic review taking on a meta-ethnographic approach  were identified. Clarke investigated nursing practices in the care and rehabilitation of in-patient stroke survivors, and found that RNs mainly focused on monitoring, and their involvement in post stroke rehabilitation was minimal . Research examining respiratory nursing care relating to pneumonia appears to be mainly quantitative in design, targeting ventilator associated pneumonia (VAP) and in the setting of intensive care units . The scarcity of literature focussing on RNs’ professional role in preventing HAP is noteworthy, especially considering its high prevalence among patients following acute stroke . Such knowledge could enhance safe practice, and facilitate the delivery of improved evidence-based respiratory care for stroke patients. Consequently, this study aimed to describe RNs’ experiences of providing respiratory care in relation to HAP, specifically among patients with acute stroke being cared for at in-patient stroke units.
A qualitative descriptive design, as per Sandelowski , was adopted to understand RNs’ experiences in relation to the study aim. The data were collected through semi-structured interviews as proposed by Polit and Beck , and were analysed using inductive content analysis [20, 21]. This study is reported in accordance with the consolidated criteria for reporting qualitative studies – COREQ  (Supplementary file 1).
Setting and participants
This study was conducted across four acute stroke units in the south of Sweden. These stroke units were selected according to the Stroke Unit Trialists’  definition, i.e., stroke units specialising in caring for stroke in-patients where nurses, together with other health care professionals, are working as a coordinated team. A purposive sampling technique was used , with eligible participants being RNs who had worked for at least 1 year in one of the four stroke units included in the study.
Information detailing the study was sent via email to the operational managers of each of the stroke units. A week after the initial contact, the operational managers were contacted via telephone. Eleven RNs agreed to participate in the study. Both verbally, and in writing, the participants were informed about the study and the researchers’ objectives, told that their information would be kept confidential, and assured that they could withdraw from the study at any time. Additionally, both oral and written informed consent was given by participants before the interviews started. Ten of the 11 participants were female, and they had all worked as RNs for 2–25 years. Their work experience ranged from 2 to 21 years. Two RNs had undergone specialised education, one being an RN in medicine, the other a district RN, while the rest each had a Bachelor of Nursing Science degree. Six had attended specific courses in stroke care.
The data for this study were collected through semi-structured interviews  over 5 weeks, in December 2018, and January 2019. The participants decided on the time and place of the interviews. They all chose their workplace as the venue for the interviews. In total, 13 interviews were conducted. Before data collection, two initial interviews were conducted to assess the quality of the semi-structured interview procedure, resulting in minor rephrasing to facilitate participants understanding. These interviews were not included in the study. Two researchers (MR and ME) conducted the interviews in Swedish, alternating as either an assistant taking notes on any non-verbal communication, or as an interviewer using an interview guide (Table 1). Probing questions (e.g., “Can you please explain further?”, “Can you please give an example?”, and “Can you elaborate?”) were used to encourage participants to elaborate on their responses . After nine interviews, no new information was provided; nevertheless, two more interviews were conducted . The interviews lasted approximately 30–40 min each, and were recorded digitally. They were then transcribed verbatim by the second and third authors (MR and ME).
The transcripts were analysed according to Graneheim and Lundman’s  description of content analysis. According to Krippendorff  content analysis constitutes a departure from an inductive methodological approach. The iterative process of analysis took place in several steps. In the first step, the transcribed texts were read repeatedly to obtain an overall understanding . In the second step, key issues (i.e., units of meaning) reflecting the aim of the study were independently highlighted with different coloured pens. Meaning units were then condensed to reflect their essence, after which they were colour coded. Next, the different coloured codes were explored and compared to identify differences and similarities. Finally, they were sorted into tentative subcategories, ensuring that the original content was preserved. While the second and the third authors (MR and ME) oversaw this analysis, all the authors conducted the process described above. The team then met several times to discuss the texts, in order to identify the most likely meaning, whilst maintaining the integrity of the content. This resulted in the authors agreeing upon 11 subcategories (Table 2).
In the final step, three overarching categories unifying the content of the 11 subcategories were formulated. These three categories were interpreted to reflect the variations in the RNs’ experiences of providing respiratory care in relation to HAP among in-patients with acute stroke.
The RNs experiences of providing respiratory care for HAP among in-patients with acute stroke could be understood in light of three overarching categories, (1) awareness of risk assessments and risk factors for HAP, (2) targeting HAP through multiple nursing care actions, and (3) challenges in providing respiratory care to patients in risk of HAP. In this section, the categories are exemplified by quotations (Q) (Tables 3–5), and sub categories are presented in italic.
Awareness of risk assessments and risk factors for HAP
In the category ‘awareness of risk assessments and risk factors for HAP’, the participants acknowledged the need to know the range of different risk factors for developing HAP in patients following acute stroke. These factors included dysphagia, immobility, nasogastric feeding, and other underlying conditions aside from acute stroke itself. In this category, the possibility and importance of taking advantage of routine care assessments to identify risks of adverse health care events were also addressed, as was the need for specialist training in the identification of HAP in stroke patients.
The participants described dysphagia as one of the most common risk factors for stroke patients in developing HAP. Therefore, as a part of standard care, some participants described that it was important for routine risk assessments of a patient’s swallowing function always to be undertaken as per Riksstroke [i.e. the Swedish stroke register aiming to ensure continuous quality improvement in Swedish stroke care] (Table 3, Q1). The national guidelines for stroke care state that a swallowing assessment should precede any oral intake of food or drinks. Different experiences were described in terms of how well this routine risk assessment of swallowing function was implemented. Some participants found that all patients admitted to their unit with a diagnosis of acute stroke received an accurate assessment of swallowing function, while others suggested that there was room for improvement in conducting these assessments (Table 3, Q2). The participants also stated that bedridden patients, or patients using a nasogastric feeding tube (NGFT), had a higher risk of developing HAP than mobile patients (Table 3, Q3), or patients without an NGFT. The latter was stated as a substantial risk factor in developing HAP, particularly in those cases where patients were confused, or were not correctly supported or positioned in bed during feeding (Table 3, Q4).
The participants also stated that patients who had other underlying conditions, for example patients with chronic obstructive pulmonary disease (COPD), or asthma, were especially vulnerable, and had an increased risk of developing HAP after an acute stroke (Table 3, Q5). This category also reflected an awareness among the participants that respiratory nursing care per se, as well as the assessment and identification of those patients with an increased risk of developing HAP, required the same assessment and identification as the mandatory quality indicators stipulated by Riksstroke (Table 3, Q6). However, some participants described that this strict focus on mandatory quality indicators in nursing care could in fact work against the identification of those most at risk of developing HAP after an acute stroke (Table 3, Q7). On the other hand, other participants expressed a wish to reinstate the quality assurance used in Riksstroke for pneumonia, as part of standard care. They stated that such an action would automatically result in the return of standard care risk assessments for pneumonia. Participants described how this formerly mandatory requirement had increased their awareness and competence as RNs, especially in regard to HAP (Table 3, Q7). Additionally, participants experienced higher preparedness for identifying HAP in stroke units, where staff had attended a course specifically focusing on patients who had suffered a stroke. (Table 3, Q8).
Targeting HAP through multiple nursing care actions
In the category ‘targeting HAP through multiple nursing care actions’ the participants suggested a variety of actions, that could be used as preventative measures for HAP, as part of nursing care. Participants acknowledged the importance of actions within several specific areas of nursing care: respiration, mobility, oral health, and nutrition. They also highlighted the importance of acting on these areas of care as a coordinated interprofessional team.
Participants stated that respiratory care targeting HAP often included breathing exercises. This was described as relying on multi-disciplinary teamwork, where members had different accountability. Some stated that it was common for both the RN and the physiotherapist (PT) to initiate and implement care actions such as these breathing exercises (Table 4, Q1). Others experienced the opposite, and described how the PT was mostly in charge of what should be done with the patient as part of respiratory care (Table 4, Q2). However, it was always the PT that assessed the degree of resistance, and determined what resistance equipment should be used for positive expiratory pressure (PEP) training, and follow-up procedures (Table 4, Q3). The RNs or the health care assistants were mainly involved in ensuring that the patients completed the exercises. The participants’ experiences of the usefulness of such PEP exercises in respiratory care targeting HAP varied. Some participants explained that the exercises were based on positive, proven experiences, while others were more sceptical and critical of the exercises, and shared experiences of implementation adherence failures when it came to supporting the patients during exercises (Table 4, Q3: Q4). The main reason given for failure was a lack of time, however participants also noted that the patients could not always perform the exercise, as they were sometimes complicated.
Mobilisation was considered by some participants to be an important preventative measure in respiratory care. Other descriptions instead reflected the different levels of knowledge among the participants in regards to the preventative effects of mobilisation on HAP, or rather, their lack of knowledge of the relationship between a bedridden patient post stroke, and HAP risk (Table 4, Q5: Q6). The participants stated that a coordinated team was the cornerstone of respiratory care, and that the PT had a central role on the team when it concerned assessment and planning of a patient’s mobilisation. Participants also described how mobilisation was a routine part of nursing care at some stroke units (Table 4, Q7: Q8). Descriptions about less optimal mobility care were also present, with a lack of time again being cited as the chief reason for suboptimal care (Table 4, Q9).
In this category, oral health was described as another important part of respiratory care in the prevention HAP. Overall, the participants found that despite its importance, oral health care was not attended to as often as it should be, nor in an optimal way (Table 4, Q11: Q12). When oral health was part of routine care, it was described principally as being performed so that the patient could feel clean and comfortable. Thus, the relationship between oral health and HAP was not reflected in the participant’s understanding of their nursing practices (Table 4, Q13).
Nutrition was also highlighted as a vital part of respiratory care, particularly as many acute stroke patients suffer from dysphagia to varying degrees. Participants described some preventative measures around meals and mealtimes to reduce HAP risk (Table 4, Q14). Positioning and repositioning were described as a routine part of nursing care around mealtimes, regardless of whether the patients ate themselves, or using a NGFT. Lack of time and resources were stated to at times negatively impact respiratory nursing care, leading to bedridden patients not always being supported in an adequate feeding position at mealtimes (Table 4, Q15).
Lastly, the participant’s experiences highlighted the importance of multi-disciplinary teamwork. Teamwork was perceived as a key strength in care, particularly as working in multidisciplinary teams meant gaining more individual knowledge, in addition to support (Table 4, Q16). The multi-disciplinary team was described as a vital asset, particularly for patients with dysphagia, where collaboration was stated as being central to preventing the patient from swallowing incorrectly, which would increase the risk of HAP (Table 4, Q17).
Challenges in providing respiratory care to patients in risk of HAP
In the category challenges in providing respiratory care to patients in risk of HAP, participants described some of the inherent trials faced in the identification and prevention of HAP. First, participants’ experiences reflected a lack of awareness regarding HAP. Additionally, care targeting HAP was not a part of standard care or prioritised in nursing care in the same way that assessing and evaluating routine health risk events were. Second, participants described a variety of contextual barriers, and at times, a general lack of competence and knowledge regarding the identification and prevention of HAP. On the one hand, general awareness of the risks of HAP was demonstrated by the participants, however, a lack of understanding relating to the risk factors leading to HAP was also found. Participants were able to describe the importance of identification and prevention of HAP, but this was not covered as a natural part of the RNs’ discussions about care (Table 5, Q1, Q2). The participants noted that while the identification and prevention of HAP was not a part of routine care (Table 5, Q3), their experiences were that some nursing interventions targeting HAP had been initiated. Notably however, participants also stated that such interventions were not a priority, and they believed that HAP could be prevented more effectively if relevant nursing care procedures were implemented (Table 5, Q4).
Several contextual challenges were described as influencing the participants in the identification and prevention of HAP. The overall organisation of care at the different units i.e. staff numbers was one such challenge (Table 5, Q5). Another challenge for nursing care targeting HAP, was that participants experienced that they were put in charge of a larger number of complex patients than previously (Table 5, Q6), and that other medical activities and emergencies often took priority (Table 5, Q7). How the ward was configured was also stated to influence the number of direct nursing encounters that the patients received. This was described as negatively impacting the participants’ potential to assess and evaluate patients for HAP. Specifically, patients in single rooms were found by the participants to receive less attention than those patients who shared a room (Table 5, Q8).
Working in an multidisciplinary stroke team was also stated by the participants to be challenging at times. They described a somewhat ambiguous experience in relation to the coordinated teamwork regarding patients with dysphagia. This was because the focus often shifted primarily to single factors, for example, nutritional needs and swallowing exercises, without taking into considering the relationship between dysphagia and HAP (Table 5, Q9). In addition, participants also described how efficient and clear communication among the team could act as a ‘wake-up call’ for the RNs to initiate further actions targeting the prevention of HAP.
Participants also experienced additional challenges, including a general lack of competence and knowledge needed to identify and prevent HAP in their units. Staff turnover was one reason given for the difficulty in maintaining the relevant competence and knowledge base needed to care for stroke patients (Table 5, Q10: Q11). High turnover also meant that competence and knowledge was spread unevenly among the participants. Being a novice RN could mean that a participant more easily missed what was required to prevent HAP. This could in turn be experienced as putting additional strain on the more experienced RNs (Table 5, Q12). Participants also described how nursing care targeting HAP in this complex and high care-dependent group of patients, could be difficult for the less experienced RNs to undertake (Table 5, Q13).
The current study aimed to describe RNs’ experiences of providing respiratory care in relation to hospital acquired pneumonia (HAP) among patients with acute stroke being cared for at in-patient stroke units. Their experiences could be understood from the perspective of three overarching categories: (1) awareness of risk assessments and risk factors for HAP; (2) targeting HAP through multiple nursing care actions; and (3) challenges in providing respiratory care to patients in risk of HAP.
Identifying acute stroke patients at risk of HAP stood out as both complex and challenging. Being able to identify at-risk patients was considered an essential part of respiratory care, and demanded that the RNs were aware of a wide range of risk factors. Several specific risk factors were described, but dysphagia in particular was emphasised as being a key risk. The latter is in line with current evidence, suggesting that dysphagia constitutes one of the major risk factors for developing HAP [25,26,27]. The high awareness of this risk factor observed here, could be explained by that mandatory swallowing assessments included as a quality indicator in Riksstroke. Riksstroke is a tool aimed at continuous quality improvement in Swedish stroke care, as well as an instrument for following up the National Board of Health and Welfare’s guidelines for stroke care . Although emphasised as a quality indicator, it was obvious that the adherence to standard practise, and the quality of swallow assessments performed, varied between stroke units. These findings imply that routine practises, and clearly defined standard quality indicators, can influence respiratory care. They also reflect individual differences among RNs, and within the multidisciplinary teams, which seem to affect adherence to standard practise doctrines, and their quality. It has previously been reported that when RNs have a positive attitude towards guidelines for the prevention of VAP, it influences their adherence to said guidelines . This implies that interventions aimed at raising RN awareness of the importance of integrating evidence-based care routines are warranted. Further, raising awareness of the guidelines regarding swallowing assessments, to support the identification and prevention of HAP among patients with acute stroke, will be important.
One particularly noteworthy finding of this work, was that RNs did not associate the increased risk of developing HAP, and the recognised risk factor of poor oral health in relation to stroke. This is despite it being common knowledge that poor oral health is a risk factor in developing pneumonia [30, 31]. Instead, oral health was described as being part of routine care, but often-neglected. Interestingly, oral care was stated as primarily being undertaken for the patients’ general well-being; not for reducing the risk of developing HAP. This is corroborated by others, as through review, Ajwani and colleagues  found an international lack of oral health knowledge among RNs. They also highlighted infrequent assistance with stroke patient oral care. Overall, this stresses the need to incorporate oral hygiene and health care into the RNs’ responsibilities when delivering the fundamentals of care to acute stroke patients. This is especially vital in relation to respiratory care, as accumulated bacteria in the oral cavity due to neglected oral care, may increase the risk of HAP . By utilising the dimension ‘integration of care needs’ in the fundamentals of care framework  as part of respiratory care, RNs may more easily understand the complex interactions between different risk factors for HAP.
At the four stroke units, that was part of this study, the identification of HAP was not described as part of standard care. Nevertheless, our findings described how the RNs conducted risk assessments and made care plans on a daily basis. These care plans mainly focused on the mandatory quality indicators outlined in Riksstroke, such as malnutrition, pressure ulcers, and falls. Focusing only on mandatory risk assessments does not constitute reasonable RN responsiveness to the needs of patients suffering from acute stroke. This may be the result from nursing care becoming more complex and technical, causing the fundamentals of nursing to be set aside [11, 34]. Such an explanation was partially corroborated by our findings, indicating that medically emergent activities, for example thrombolytic treatments, were often given higher priority than respiratory care per se.
Although preventative respiratory care to avoid HAP did not stand out as a standard clinical practise, our findings showed that when preventative nursing actions were conducted, it was not evident to the RNs that their actions could impact more than one of the known risk factors for HAP . For example, the relationship between pneumonia and impaired mobility in relation to mobilisation and positioning . It could be argued that RNs are expected to possess knowledge, competencies, and skills to plan preventative nursing care for HAP. In particular, this issue concerns RNs working in a stroke unit where HAP is not an unusual complication. Our findings indicate that further knowledge is needed among RNs about the development of safe and high-quality respiratory care for acute stroke and HAP. One way to achieve this, and to give respiratory care higher priority, may be to implement systematic and purposeful nursing rounds. Checking on patients at regular intervals can act as a primary procedure to address the patient’s essential personal needs [35, 36]. The fundamentals of care formulated by Kitson and colleagues  could be used to develop such a protocol, constituting the basis for observations during nursing rounds.
Earlier studies have shown that higher education levels, e.g., a Bachelor in nursing , and greater experience in working as an RN , are factors associated with a reduced incidence of complications such as pneumonia during hospitalisation. This is corroborated by our findings, in which RNs with a long work history in stroke care, and a higher educational level, appeared to better recognise and meet the complexities of the patients’ need for care. For less experienced RNs, it seemed like a challenge to assess, diagnose, intervene, and evaluate nursing care for patients with complex care needs. The respiratory care offered to the patients in relation to HAP seemed to be dependent on the individual RN’s competence, and therefore, was most likely inconsistent, and unequal. Consequently, higher priority should be given to respiratory care, as this will likely diminish the risk of HAP, resulting in faster rehabilitation trajectories, and shorter hospital stays for patients. One approach in the reduction of HAP incidence and improvement of respiratory care for patients with acute stroke, would be the implementation of evidence-based guidelines for the identification and prevention of HAP. Using such guidelines, routines, and care pathways can reduce the risk of HAP [38, 39]. Additionally, they increase the quality of nursing care, and address the diversity of care-related processes that are pivotal to diminishing risks , such as the possible impact of inconsistency in respiratory care.
Safe and high-quality care can only be achieved if the context in which RNs work is prepared to support nursing and nursing care. Our findings implied that the RNs paid less attention to direct patient care e.g., oral health, mobilisation and respiratory care. A possible explanation could be that they decided that such nursing care not was a priority. According to Maenhout and Vanhoucke , organisational structures and processes are known to affect the quality of care and the work environment of RNs. The inability to manage care effectively, threatens both the quality and safety of care . Our findings also implied that a shortage of experienced nursing staff, high staff turnover, and patients’ more complex needs might explain the reality of a de-prioritisation of nursing care at some of these stroke units. The latter is corroborated by previous research , showing that similar barriers exist in preventing VAP. Indeed, nursing staff shortages have been described as an influential factor impeding the prevention of health-related complications such as pneumonia . Additionally, to maintain a safe standard of care, it has been recommended that RNs are responsible for only two patients at a time during the acute phase of a stroke, and after that, only four patients . In the current study, the RNs found that at times they did not actually have sufficient control over patient care to be able to identify HAP. For this reason, actual patient complexity and error margins to allow for complications and suboptimal timing must be considered when staffing is planned, rather than simply the number of patients that each RN is assigned responsibility for.
Modern stroke care is becoming increasingly centred around collaborative stroke units, this being a major factor in the improved number of stroke survivors . The RNs in our study considered the multidisciplinary team a valuable resource in providing the respiratory care required to identify and prevent HAP. Nursing should be a part of multidisciplinary teams , but the RNs are ultimately responsible for the patients’ nursing care. Despite this, our findings implied that some of the responsibilities and initiatives for the patients’ care, such as mobilisation, positioning, and swallowing assessments, were left to the other members of the team. This result is corroborated by the findings of Clarke , in which RNs working in a rehabilitation stroke unit mainly focused on monitoring physical care, instead of integrating nursing with therapy work. Burton and colleagues  also found that no integration of therapist-initiated activities into fundamental aspects of nursing practice took place. They additionally noticed differences in therapeutic approaches, where RNs appeared safety driven, while the therapy staff stood out as much more comfortable with the notion of risk-taking . To take the lead in care demands competent and knowledgeable RNs, however, at times our findings instead reflected a lack of knowledge and competency in the ability to identify and prevent HAP among acute stroke patients. The latter is especially concerning, considering the highly specialised environment that a stroke unit should reflect.
Our qualitative descriptive study design meant that emphasis could be placed on the interpretation of participants’ experiences. This is particularly useful when the aim is to describe experiences unconditionally, or to find answers to the what, how, and why questions . Using purposive sampling supported variation, as the participants worked at four stroke units, each representing different routines and organisations of care, which is likely to support the study’s generalisability [cf. 19]. Although the current study provides some valuable insight into RNs’ experiences of nursing care regarding post-stroke pneumonia, it is based on a small sample size (n = 11), which may have implications regarding its transferability. Nonetheless, securing large sample sizes is not a priority in qualitative study designs. Here, the focus lies instead on the included participants being able to provide different experiences of the phenomenon under study . Guidance on the notion of response saturation was received after nine interviews, when no new information emerged from further interviews.
Using content analysis provided us with an opportunity to structure and present our findings according to three broad categories. However, there is always a risk of bias, i.e. subjectivity in data interpretation. It is therefore important to account for the researchers’ preconceptions, as these can influence both the questions posed during the interviews, and how the data are understood . Two of the researchers (ME and MR) work within stroke care, while the other two (GB and MA) do not. Thus, to reduce the risk of subjectivity, and to improve the credibility of the current study, all authors took part in the development of the interview guide, as well as the analysis . By describing the process of analysis and presenting quotations from the interviews (Table 3, 4 and 5), we aim to allow the reader to transparently judge our interpretations . Qualitative studies such as this one are restricted in regard to transferability, as well as in applicability to other settings, and this needs to be considered when evaluating the findings.
Conclusions and clinical implications
Respiratory care to prevent HAP among patients suffering from acute stroke is vital, however the findings from this study suggest that RNs may experience organisational challenges in providing such care. There is a need for increased knowledge relating to complex interactions in nursing, i.e., that some preventative nursing actions can influence more than one risk factor. For instance, poor oral health is associated with malnutrition and poor well-being, but also with an increased risk for HAP. Furthermore, procedures for identifying patients at risk of HAP need to be implemented, and RNs need better education in order to take ownership of respiratory nursing care within multidisciplinary teams. HAP is among the most common and serious respiratory complications experienced by patients with acute stroke. It causes distress, increased healthcare costs, morbidity, and even mortality. Respiratory care plays a vital role in the identification and prevention of HAP, but for it to be implemented successfully, RNs’ knowledge needs to be improved, the fundamentals of nursing care need to be prioritised, and evidence-based guidelines must be introduced. Moreover, RNs need to be offered further educational training, so that they can effectively lead nursing care in multidisciplinary stroke teams.
