Abstract

Aim

To investigate the current state and influencing factors of core competence of oncology specialist nurses as well as the relationship between core competence and perceived professional benefits.

Design

A cross‐sectional correlational survey.

Methods

This questionnaire survey was conducted with oncology specialist nurses working in a Grade III A (tertiary) Public Cancer Hospital in Jinan, China in March 2021. Based on informed consent, a convenience sampling of 350 nurses participated in the study, with 322 valid questionnaires collected. Using IBM SPSS21.0, the data were analysed to perform descriptive statistics, analysis of variance (ANOVA), multiple stepwise regression analysis and Pearson's correlation analysis.

Results

The overall average score of nurses' core competence was 224.28 ± 7.95, a medium level and the overall average score of their perceived professional benefits was 132.99 ± 5.05. Nurses' core competence was positively correlated with perceived professional benefits. The differences in professional title, education, working years and perceived professional benefits were statistically significant.

Conclusion

The findings indicated that nurses' perceived professional benefit is an important factor affecting core competence. Nursing managers who take main responsibility for the quality of care should adopt measures to increase perceived professional benefits, which not only promote nurses' job satisfaction and happiness, but also enhance the development of their core competence and the quality of cancer care as well.

Patient or Public Contribution

All participants contributed to the conducting of this study by completing self‐reported questionnaires.

pmc1 INTRODUCTION

An estimated 19.3 million new cancer cases and almost 10 million cancer deaths occurred globally in 2020 (Sung et al., 2021). It was predicted that the number of individuals diagnosed with cancer would increase progressively over the following decade, which would reach 22 million new cases and 13 million deaths worldwide by 2030 (Dent et al., 2017). The incidence and mortality of patients with cancer in China is rising year by year, and there was 22% probability that people would suffer from malignant tumours (Ding & Wang, 2015). Due to cancer patients' relatively long treatment time and the shift in their perception of cancer from ‘death penalty’ to a chronic disease, the number of oncology specialist nurses is on the steady rise, which is not keeping pace with the increase in cancer incidence in the United Kingdom (Henry, 2015). Oncology specialist nurses have the vital responsibilities of providing counselling and psychological support, managing pain and symptoms, engaging in research and teaching, etc., though healthcare systems in different countries vary in their requirements for oncology clinical nurse specialist roles (Kapra et al., 2023). They have a significant impact on the quality of patient care and have demonstrated their cost effectiveness, which will greatly address the increase in oncology patients and the shortage of doctors (Henry, 2015). Nurses' core competence is the key to delivering the high‐quality and effective care (Chen, 2010). It is defined as ‘a standard set of performance domains and their corresponding behavioural standards which a nurse is required to demonstrate’ (Singapore Nursing Board, 2018, p. 1). No consensus has been reached on the dimensions or domains involved for nurses at varying levels and in different clinical fields. The Advanced Practice Nurses' core competence encompasses four domains: clinical practice, leadership and decision‐making, education and mentoring, and scientific research (Honig et al., 2019). Oncology Nursing Society (ONS) published expectations for different roles in oncology through Oncology Clinical Nurse Specialist Competencies, and ONS described three spheres, namely patient/client sphere of influence, nurse and nursing practice sphere of influence and organization/systems sphere which involves assessment of health status, diagnosis of health status and plan of care, interventions, evaluation, etc. (ONS, 2008). Liu and Liu (2014) summarized them into five dimensions: clinical practice ability, management ability, critical thinking ability, communication and coordination ability and professional development ability. The researchers from different regions or countries have a varying version of the core competence for oncology specialist nurses, but the basic content is almost the same, which commonly includes critical thinking ability, clinical practice ability, professional development and management ability, coordination and communication ability, etc. (Chen, 2017). Boosting nurse's core competence is the key not only to improve the quality of patients care, but also to retain the nursing workforce (Takase et al., 2015). Furthermore, it leads to the improvement of overall satisfaction scores related to patient's services due to the moderate cost benefits (Kerr et al., 2021).

Nurses' perceived professional benefits (NPPB), which originated from positive psychology, refer to ‘the gains and benefits nurses perceived that they received from their profession in the process of employment and the belief that engaging in the nursing profession can promote their all‐round growth and development’ (Hu, 2013; Hu et al., 2020, p. 1, direct quote). The term ‘professional benefits’ was first raised in 1995 in clinical nursing education research when preceptors perceived benefits or rewards from the teaching profession (Dibert & Goldenber, 1995). This positive occupational emotional experience plays a positive role in boosting personal physical strength, social coordination and intelligence, enhancing one's knowledge and action competence and promoting self‐development (Fredrickson, 2001). Many previous studies have demonstrated the importance and benefits of NPPB. It can reduce nurses' burnout and negative emotions, strengthen their job satisfaction and subjective sense of happiness (Shi et al., 2016; Xiao et al., 2016). Moreover, it is conducive to nurses' innovation, devotion and dedication to their nursing work (Hu & Liu, 2013). This invisible incentive factor can promote the professional development of nurses and provide better services for patients (Zhang et al., 2015).

With the substantial boost of people's health and nursing needs, patients with cancer require high‐quality nursing, which needs highly competent nurses arising from many factors such as education level, professional title and working environment. Core competence is essential for nursing work. A better understanding of the factors affecting core competence should make the nursing service better and more efficient. As positively commented previously, NPPB can promote nurses' professional development and self‐growth, and nurses' positive occupational emotional experience from NPPB helps to give full play to their potentials in nursing work. Li et al. (2022) found the positive correlation between spiritual care competency and perceived professional benefit among nurses. Then is there a relationship between oncology specialist nurses' core competence and NPPB? Based on the literature, the following hypothesis was proposed:

A positive relationship will be found between oncology specialist nurses' core competence and NPPB.

The rationale for exploring the relationship between them is grounded in the need to find the relevant factor of boosting core competence to provide high‐quality care for patients with cancer.

2 METHODS

2.1 Design and participants

In this cross‐sectional correlational study, a convenience sample of oncology specialist nurses from a tertiary public Cancer Hospital in Jinan, China was recruited in March 2021. This hospital, the largest cancer hospital in Shandong province, is a representative of top cancer hospitals in China. Oncology nurse specialist refers to those nurses who have specialized knowledge, expertise, competences and experience in a particular oncology field, such as pain management, psychological care, nutrition after registering voluntarily, completing about 1‐year relevant training courses, passing the qualification test and getting the certification of oncology nurse specialist from the oncology specialist nurse training base approved by the Shandong Provincial Healthcare Department. Inclusion criteria were as follows: (1) those who obtained the qualification certificate of oncology nurses in the hospital before March 2021; exclusion criteria: (1) nurses in maternity leave, sick leave and personal leave; (2) nurses who were studying for a qualification certificate; (3) those who voluntarily gave up the qualification of nurses.

2.2 Data collection

First, the deputy director of the hospital's nursing department sent notices to different nurses' working groups on social media (e.g. WeChat), informing the participants of the research purpose and other important information such as filling in the questionnaire anonymously, inclusion criteria and exclusion criteria in written message. A worker from the nursing department and an investigator distributed 350 questionnaires to oncology specialist nurses in different working groups. Three hundred and twenty‐two valid ones (excluding incomplete information) were obtained for statistical analysis. The ethics committee of the hospital approved the study (no. 2020‐S118), and the survey questionnaire included an informed consent statement for their participation in the survey.

2.3 Measurements

The questionnaire consisted of three parts: demographic information, core competence scale and perceived professional benefits questionnaire. Demographic information included the participant's subspecialty, professional title, educational level, years of service and marital status. The established core competence scale for oncology nurses, developed by Liu and Liu (2014), contained 56 items organized under 5 dimensions which are clinical practice (23 items), management (6 items), critical thinking (8 items), communication and coordination (8 items) and professional development (11 items). Each item was scored on 5‐point Likert scale. The higher the score, the higher the core competence. The overall reliability Cronbach's α coefficient of the scale was 0.845, the Cronbach's α coefficient of five dimensions was 0.804, 0.712, 0.785, 0.826 and 0.863, respectively. The content validity I‐CVI was 0.79–1.0, and the internal consistency coefficient was 0.817–0.932.

Nurses' perceived professional benefit questionnaire, a psychometrically sound measure, compiled by Hu and Liu (Hu, 2013; Hu et al., 2020; Hu & Liu, 2013) had 33 items over five dimensions which involved positive professional perception (7 items), good nurse–patient relationship (6 items), family and friend identity (6 items), team belonging (6 items) and self‐growth (8 items). Each item was rated at a score of 1–5, and the score was positively counted, and positively correlated with the level of professional benefit. Total score ranged from 33 to 165. Scores of 132–165 were classified as high level group, 99–131 as moderate level, 66–98 as lower‐level group and 33–65 as low‐level group. The overall Cronbach's α coefficient of complete questionnaire and five dimensions was between 0.821 and 0.958, and the split‐half reliability coefficient was between 0.813 and 0.938.

2.4 Statistical analysis

SPSS21.0 (IBM Corp., Armonk, NY, USA) was used to analyse the data, mean, standard deviation, frequency, percentage and one‐way ANOVA was performed to describe and infer the data.

3.5 Analysis of influencing factors of oncology specialist nurses' core competence

Using single‐factor analysis of variance, the general data of professional title, educational background, working years and perceived professional benefits affected their core competence to a certain extent, as detailed in Table 5. As for the five dimensions of core competence, it can also be seen that both educational background and working years affected management ability; educational background affected professional development ability respectively. Perceived professional benefits had an impact on both critical thinking ability and communication and coordination ability that is simultaneously influenced by educational background and working years. Taking the core competence of nurses as dependent variables, basic data and professional benefit as independent variables, multiple stepwise regression analysis was carried out. The results showed that ‘working years’ and ‘educational background’ entered the regression model of core competence of nurses in the hospital (see Table 6 for details).

4 DISCUSSION

In the present study, the findings demonstrated that the total average score of core competence of oncology nurses was moderate, which was consistent with the results of previous studies (Wei et al., 2016).The reason may be that compared with western specialized nursing, Chinese nursing education started late and specialist nursing is still at an underdeveloped stage. Additionally, due to the emerging advanced diagnostic technology and the drastic change of living habits and food over the past years, the soaring number of diagnosed cancer cases in China overburdened oncology specialist nurses, which might be a factor leading to the present situation of core competence. In this study, each dimension of nurses' core competence was unbalanced. The top prominent core competency of nurses was clinical practice ability, which indicated that the nurses' clinical ability was predominantly underscored in the hospital and nursing knowledge and expertise could be well applied to clinical practice. The dimension with relatively low score was critical thinking ability, which was also reported in Su et al.'s studies (Su et al., 2016). Currently, nurses' critical thinking and research ability fail to receive much attention in hospitals, and a very limited number of nursing students who obtained master's or doctorate degree chose to work as a nurse in hospitals.1 Many studies have shown that critical thinking has a far‐reaching impact on nursing scientific research and nursing work. And it is also an important part of the core competence of nurses (Lopes et al., 2022). Therefore, more research training should be offered to improve the critical thinking ability of specialist nurses (Xu et al., 2014).

In this study, the overall average score of professional benefits of nurses was at a relatively high level, which was in line with the results of many previous studies (Li et al., 2021; Mao et al., 2016; Zhan et al., 2020; Zhou et al., 2019). This indicated oncology nurses perceived the benefits from the nursing work and recognized the value and significance of their work. Particularly, during the COVID‐19 pandemic, large numbers of nurses who were dispatched to other affected areas in China to fight against the COVID‐19 received much recognition and praise from the hospital and public (Li et al., 2022). This sense of pride and fulfilment increasingly enabled them to better understand and value their job. The dimensions with higher scores were positive professional perception and self‐growth. The reason may be that with the widespread and effective application of modern medical technology, chemotherapy and radiotherapy, more patients with cancer can be treated and even cured under the direct care of nurses. This positive professional emotional experience narrows the psychological distance between nurses and profession, prompts them to obtain benefits and psychological satisfaction, and forms a positive and optimistic cognitive style and emotional experience. Moreover, patients with cancer have multi‐faceted nursing needs physically and psychologically, which depend on nurses' work considerably. This, on the one hand, reflects the value and significance of the nursing profession; on the other hand, it raises more challenges for nurses. The high requirements of oncology knowledge and practical skills urge the nurses to continuously improve their comprehensive literacy, so as to promote the maturity of professional mentality and professional ability, and will also form a positive professional experience. This positive emotional state is a kind of satisfaction for individuals, and they can realize that this is conducive to their own better development and growth (Fang, 2019; Zhao, 2018).

In this study, among the surveyed influencing factors of oncology specialist nurses' core competence, professional title, educational level, working years and perceived professional benefits affected the core competence to some degree. There were significant differences in terms of the core competence of nurses with different professional titles (p < 0.05), which was consistent with the research results by Yang and Huang (2016). It is mostly due to the fact that the professional title is the most direct embodiment of nurses' working ability. The higher professional title indicates that they perform clinical work more skilfully. With a stronger clinical judgement, the problems they encounter in cancer care can be detected and tackled effectively in time. Different levels of education determines their ability to understand things. In this study, there were significant differences for core competencies of nurses with different levels of education (p < 0.05). Nurses at a higher level of education showed higher core competencies in their work. Highly educated nurses are more likely to receive much attention and support from hospital administrators and have more opportunities to conduct scientific research and nursing practice presentation in hospitals, so that their specialties can be brought into full play and displayed. Working years affect the nurses' working ability and nursing quality. In this study, the core competence improved with increasing working years. The longer their working years is, the richer clinical practical experience they may have. This result was congruent with previous studies in which nurses with more years' clinical experience had a higher competency in making appropriate clinical judgements, implementing planned nursing care, and evaluating outcomes (Sasaki et al., 2013). Therefore, the accumulation of good working experience plays a positive role in nursing career development. As for the five dimensions of core competence, education background and working years affected management ability. For one thing, nurses with a higher education level are more equipped with knowledge and expertise to cope with the problems in the work, which prepare himself/herself for effective management. For another, long working years enable nurses to learn and accumulate much work and management experience, particularly from head nurses. Educational background is an important influencing factor for one's professional development ability. As mentioned previously, nurses with a higher educational level have more opportunities of promotion and gain more support from the hospital, so that they have better professional development space, which further enhances their overall ability, including professional development ability and management ability.

Perceived professional benefits increase nurses' psychological resilience and devotion to nursing, and have a positive influence in reducing nurses' professional fatigue and turnover (Duan et al., 2017). But the correlation between the core competence and sense of professional benefits of oncology specialist nurses has not yet been clarified. Our study shows nurses' core competence was positive correlated with NPPB which was a good predictor of the core competence. That is, as an affirmation of the profession and positive emotional experience, the sense of professional benefits, an inherent incentive for nurses' professional development, has a positive impact on the core competence. With a sense of professional benefit and a higher professional identity, the nurses are highly motivated to stay on the job and better give full play to their potentials in their career (Sabanciogullari & Dogan, 2015). Their oncology theoretical knowledge and practical skills can be better integrated and applied to the clinical work, and then their core competence are more likely to be enhanced. Therefore, a stronger sense of perceived professional benefit will promote a higher level of core competence which is essential to meet the goals of quality, safety and satisfaction for the patients (Donilon, 2013).Although NPPB is relatively high in this study, there is a large room for improvement, because overall, Chinese nurses have heavy workload, widespread professional fatigue and rising turnover rate (Xu et al., 2022). Nursing managers should guide nurses in realizing NPPB and use it an effective strategy to boost their core competence. As a positive emotional experience, NPPB not only promotes nurses' job satisfaction and subjective sense of happiness, but also enhances the development of their core competence, which gives full play to their professional potentials and optimizes nursing quality. NPPB can be effectively improved by employing nurses' cognitive evaluation interventions, stress‐reduction interventions, writing down mood diaries, benefits‐seeking guide education such as helping nurses' build positive professional perception and providing them more chances of self‐growth (Xu et al., 2022).

5 LIMITATIONS

Some limitations need to be taken into account. First, convenience sampling in a hospital was used in this study instead of random sampling. Second, the sample size was not sufficiently large. Third, we used self‐reporting questionnaires in which participants might have a response bias inconsistent with the actual situation.

6 CONCLUSION

This study revealed that oncology nurses' core competence and perceived professional benefit were at medium and high levels, respectively, and that there was a positive correlation between them. As a predictor of nurses' core competence, nurses' professional benefit can be fully utilized to boost the core competence, which, in turn, promotes professional development and improves the quality of care for patients.

DATA AVAILABILITY STATEMENT

The data that support the findings of this study are available from the corresponding author upon reasonable request.

1 In China, an overwhelming majority of clinical nurses in hospitals have a 3‐year diploma or 4 or 5‐year bachelor's degree in nursing, but due to fierce competition in employment, recently, a very small number of nurses with a master's degree (3‐year program after getting Bachelor of Science in Nursing) began to be recruited for clinical practice. All nurses can be engaged in research, but normally nurses with a master's or doctoral degree have the capability to do research, because they receive research methodology training at university.
