Abstract

Background: The nursing process is a systematic method of planning, delivering, and evaluating individualized care for clients in any state of health or illness. Many countries have adopted the nursing process as the standard of care to guide nursing practice; however, the problem is its implementation. If nurses fail to carry out the necessary nursing care through the nursing process; the effectiveness of patient progress may be compromised and can lead to preventable adverse events. This study was aimed to assess the implementation of nursing process and associated factors among nurses working in selected hospitals of central and northwest zones of Tigray, Ethiopia, 2015.

Method: A cross sectional observational study design was utilized. Data was collected from 200 participants using structured self-administered questionnaire which was contextually adapted from standardized, reliable and validated measures. The data were entered using Epi Info version 7 and analyzed using SPSS version 20 software. Data were summarized and described using descriptive statistics and multivariate logistic regression was used to determine the relationship of independent and dependent variable. Then, finally, data were presented in tables, graphs, frequency percentage of different variables.

Result: Seventy (35%) of participants have implemented nursing process. Different factors showed significant association. Nurses who worked in a stressful atmosphere of the workplace were 99% less likely to implement the nursing process than nurses who worked at a very good atmosphere. The nurses with an educational level of BSc. Degree were 6.972 times more likely to implement the nursing process than those who were diploma qualified. Nurses with no consistent material supply to use the nursing process were 95.1% less likely to implement the nursing process than nurses with consistent material supply.

Conclusion: The majority of the participants were not implementing the nursing process properly. There are many factors that hinder them from applying the nursing process of which level of education, knowledge of nurses, skill of nurses, atmosphere of the work place, shortage of material supply to use the nursing process and high number of patient load were scientifically significant for the association test.

Background The nursing process is a systematic method of assessing, diagnosing, planning, delivering and evaluating individu- alized care for clients in any state of health or illness. Based on the scientific problem-solving method, it con- stitutes the foundation for nursing practice [1]. The nursing process has been described as a theory of how nurses organize the care of individuals, families and communities. Lydia Hall was the first person to intro- duce the concept of “nursing process” into nursing in 1955 while addressing a group of nurses in New Jersey. The theory of the nursing process has been largely ac- cepted by nurses since 1967 [2–4]. The nursing process has become the basis of contem-

porary practice of a core component of nursing educa- tion as well as a point of reference in providing nursing care in many parts of the world. Arguably it is central to all nursing actions, applicable in any setting and within any frame of reference [5, 6]. In practice, however, not all steps are systematically implemented. Studies have re- vealed difficulties in establishing and using the nursing process within institutions during the last years espe- cially in developing countries [7]. In Africa, many countries have adopted the nursing

process, but problem are found in its implementation in the clinical setting. A study conducted in four African countries found that while nurses generally agree on the benefits of the nursing process, it is not commonly used in practice. The constraints identified by the study in- cluded, its time consuming nature, failure of nurse leaders to motivate others, shortage of staff and negative attitudes [8–10]. The government of Ethiopia places em- phasis on quality of health service in general and quality of nursing care in particular [11]. However, there is still a gap in the implementation of nursing process among nurses working in hospitals. One recent study found that almost all of the nurses in Mekelle hospital reported that they did not use the nursing process during the provision of care to their patients [12]. Similarly a study conducted in Debremarkos and Finote Selam hospitals in Ethiopia showed that nursing process was imple- mented by only 37.1% [13]. There are different factors which affect the implemen-

tation of the nursing process in hospitalized setting. In- stitutional factors like organizational structure and facilities in both material and human resources are one of categories of factors that affect the implementation of the nursing process. The other category of factors is nursing factors for example knowledge, especially for formulation of nursing diagnosis in developing nursing care plans, skill, experience, interest and beliefs of nurses on the importance of the nursing process. These greatly affect the implementation [14–18]. Theoretically, if nurses fail to carry out necessary nursing care, then the

effectiveness of patient progress may be compromised and can lead to preventable adverse patient events [19–21]. Although implementation of the nursing process was

well investigated throughout much of the developed world, the issue has only rarely been researched in the developing countries including Ethiopia [9]. Therefore this study was intended to assess the implementation of nursing process and associated factors among nurses who work in hospitals in central and northwest zone, Ti- gray region of Ethiopia.

Methods Study area and study period The study was carried out in central and northwest Ti- gray region, Ethiopia from December to June, 2015. In this region there were eight hospitals; of which two were zonal, five were district level and one was a defense hos- pital. St. Mary and Sehul hospitals were zonal hospitals and each of them serve approximately about one million populations. On each of the two zonal hospitals there were more than 100 nurses on average. Adwa, Temben, Enticho, Shiraro and Mytsebri hospitals were a district hospital and each of them serve roughly 200,000 popula- tions. In each of the five hospitals there were more than 60 nurses on average [22].

Study design A cross-sectional observational study design was conducted.

Source of population All staff nurses who have been working in St. Mary, Adwa, Suhul and Temben hospitals in central and northwest zones of Tigray region of Ethiopia.

Study population All sampled staff nurses who have been working in St. Mary, Adwa, Suhul and Temben hospitals in central and northwest zones of Tigray region of Ethiopia.

Selection criteria Inclusion criteria Sampled nurses who were working in St. Mary, Adwa, Suhul and Temben hospitals which were found in cen- tral and northwest Tigray region of Ethiopia.

Exclusion criteria Nurses who were temporary re-assigned, on annual leave, free service workers and those who declined to participate in the study.

Sampling Sample size determination The sample size was determined based using the follow-

ing assumption and a single population proportion (p) n

¼ Z∞=2ð Þ 2 P P‐1ð Þ

d2 was employed.

Where n is sample size desired, z2 is a standard nor- mal score of 95% of confidence interval = 1.96, d is de- gree of accuracy or the margin of error = 0.05 and p = 37.1%, which was the population proportion of the nurses who implement the nursing process using the previous study in Debremarkos and Fnote Selam hospi- tals, Amahara, Ethiopia [13]. Since the total source of the population was less than ten thousand which was 368; then by using the correction formula and thus by adding 10% for the possible non-response rate, a total sample size of 200 was obtained. Proportional allocation to the size was employed to allocate the sample among the hospitals.

Sampling procedure Of the seven hospitals in the two zones, St. Mary, Adwa, Suhul and Temben hospitals were selected through a random lottery process. After proportion allocation of the sample among the selected hospitals was employed, the sampling frame of the hospitals was prepared. From the sampling frame, 200 nurses were selected by simple random sampling proportionally for each hospital. Since nurses have the right to decline and be considered as non-respondents, those nurses who declared their wish not to participate were treated as neutral (Fig. 1).

Data collection procedure Data were collected through a structured self-administered questionnaire and observational checklist. The data collec- tion was collected by inviting 4th year Nursing Students of Axum University who were in internship practice in the hospitals under close supervision of the principal investiga- tor from April 1 to May 2, 2015 to distribute and collect the surveys.

Data collection tool The questionnaires were adapted from a previous study. The validity of the data collection tool was de- termined by two experts and seniors with reliability

of skill measurement questions, with a Cronbach’s alpha of 0.86. A structured English version question- naire contains five main parts. Part I was used to col- lect data about nurses’ socio demographics, part II about nurse implementation status of the nursing process, part III about different factors, part IV about knowledge and part V about skill of nurses in nursing practice [15].

Data quality assurance To assure data quality, training and orientation was given for the data collectors by the principal investigator. The data collection tool was pre-tested on 5% of the par- ticipants two weeks before the actual data collection period in Mekelle hospital. Similarly necessary cor- rections and amendments were considered. During data collection, data collectors checked the data for its completeness and missing information at each point. Furthermore, data were checked during entry and compilation before analysis.

questions and observed for their performance were as implementing the nursing process properly. Nursing practice skill:- Those participants who

scored >40 are highly skillful; 30–40 are moderately skillful, and <30 are low skillful groups out of 50 [15]. Knowledgeable Nurses:- Those participants who

scored 80% were considered highly knowledgeable, 55–79.9% were considered moderately knowledgeable and <55% were low knowledgeable. For the purpose of the analysis which was based on literature, low and moderate knowledgeable and skilled nurses were com- bined together resulting in two categories only, high and low knowledgeable and skilled nurses [15].

Data analysis procedure After checking the data for its completeness, missing values and coding of questionnaires, data were entered into Epi info version 7, and analyzed using SPSS version 20. The statistical analysis was made at the 95% confi- dence level and with a 5% margin of error. The data were summarized and described using descriptive statistics. Multivariate logistic regression was used to determine the relationship between the independent and dependent vari- able. The independent variables; which were included in the multivariate logistic regression, were selected by doing a bivariate logistic regression with a cutoff point of p-value less than 0.3 and the goodness of fit model was checked by the Hosmer-Lemeshow statistic. Then these variables with P-value of <0.05 at 95% confidence interval (CI) were declared as statistically significant.

Ethical considerations Ethical approval was obtained from the research eth- ical review board of Mekelle University College of Health Sciences. An official letter of permission was obtained from Tigray Regional Health Bureau and was submitted to the respective selected hospitals. Written consent was obtained from each nurse prior to data collection. Participants were allowed to refuse or discontinue participation at any time up to data analysis. Information was recorded anonymously, and confidentiality and beneficence were assured through- out the study period (Additional file 1).

Dissemination and utilization of result The result of this research will be submitted to the Min- istry of Health and Tigray Regional Health Bureau. The result will also be communicated with the hospitals where the research was done.

Result Socio demographic characteristics of the respondents In this study, 200 nurses were included. Among the partici- pants 123 (61.5%) were female, the age of the participants

ranged from 17 and 55 years with a mean age of 32.74 years and a standard deviation (SD) of ±8.94 years. Age distribu- tion of study participants was not normally distributed, so median was used as the measure of central tendency. Ap- proximately 53% of nurses were at age of 30 and below, or 106 nurses. And 111 (55.5%) held a Bachelor of Science in nursing degree at their level of education (Table 1).

Nursing process implementation status Seventy (35%) of participants had the implemented nurs- ing process in their practice while 130 (65%) had not im- plemented nursing process. Of these 124 (95.4%) nurses were not using the North America Nursing Diagnosis As- sociation (NANDA). From those nurses who implemented the nursing process 28.6% were diploma educated while 71.4% were degree (or BSc) educated (Fig. 2).

Organizational related factor One hundred twenty (60%) of the nurses were taking care up to six patients per day with at mean of 6 patients per day (SD ±2 patients). 127 (63.5%) nurses were work- ing overtime with a mean of 5.45 h (SD ±1.62 h). One hundred four (52%) of participants reported that they did not have necessarily equipments to perform a nurs- ing care while 102 (51%) of participants reported that there was no consistent supply of materials to use the nursing process in their practice. Seventy five (37.5%) of nurses were working in a stressful atmosphere of the work place. One hundred fifty three (76.5%) of nurses responded there is nurse turnover in the hospital; of

which 32.7% responded leaving to work for higher pay- ing non-governmental organizations is the leading rea- son for the nurse turnover and 75.2% nurses reported that the nurse turnover had affected their nursing process implementation (Table 2).

Nurses related factor Work experience of participants varied from one to twenty nine years with a mean of 10 years and SD of 8 years. Forty eight (24%) of the nurses reported a great strain due to a symptomatic manager. One hundred fifty seven (78%) of the nurses were dissatisfied with their job; of which 66 (42%) were dissatisfied due to the pa- tient workload and 131 (83.4%) nurses reported that dis- satisfied had affected their use the nursing process. In regards to knowledge and skill of nurses to implement the nursing process; 79 (39.5%) of the nurses had low knowledge of the nursing process while 92 (46%) nurses were moderately skilled in the activity of nursing care (Table 3).

Multivariate analysis result by factors affecting NP implementation In bivariate analysis 12 variables met the criteria that p-value <0.3 in order to use multivariate analysis. Multicolinarity was near to one tolerance and <2 VIF. Six variables were significantly associated with P-value of <0.05 at 95% confidence interval. Nurses who have BSc. degree in their educational level are 6.972 times more likely to implement the nursing process than diploma-educated nurses when adjusting for all other factors (AOR = 6.972, 95% CI = 1.13–43.1). nurses with no consistent material supply to use the nursing process were 95.1% less likely to implement the nurs- ing process than these nurses who had consistent ma- terial supply when adjusting for all other factors (AOR = 0.049, 95% CI = 0.008–0.286). Nurses who worked in a stressful work place atmos-

phere were 99% less likely to implement the nursing process than nurses who worked in a very good atmos- phere when adjusting for all other factors (AOR = 0.01,

95% CI = 0.001–0.091). Nurses who had a high patient load were 98.7% less likely to implement the nursing process than nurses who did not have a high patient load when adjusting for all other factors (AOR = 0.013, 95% CI = 0.001–0.13). Highly knowledgeable nurses

were 15.09 times more likely to implement the nursing process than low knowledgeable nurses by adjusting all other factors (AOR = 15.09, 95% CI = 1.93–117.85). And highly skillful nurses were 22.16 times more likely to im- plement the nursing process than these low skilled nurses when adjusting for all other factors (AOR = 22.16, 95% CI = 3.01–122.64) (Table 4).

Discussion This study determines the level of nursing process im- plementation and associated factors among nurses in se- lected hospitals in the central and North West zone of Tigray, Ethiopia. In thise study of 200 nurses, there was a 35% of level of nursing process implementation. This study had a lower level of nursing process implemen-

tation than a study conducted in Nigeria (in Abakaliki II and Calabar teaching hospitals) which showed a 67.2% and 62.7% respective use of the nursing process. In contrast, of

this study the variation of the level of nursing process imple- mentation may be because of the difference between the country level of development, sociodemographic factors for nurses and organizational structure and facilities. Also it is lower than study done in Addis Ababa, 2014 (52% of the level of implementation). Since Addis Ababa is the capital city of the country, the hospitals have better organizational facilities, human resources with the educational level of BSc and above, equipment access and material supply which contribute to better implementation of nursing process than the hospitals found in the regional towns. Therefore the above reasons may lead the discrepancy of the level of nurs- ing process implementation [8, 10, 16]. The level of nursing process implementation from a

study done on the assessment of the nursing process im- plementation and associated factors among nurses in Debremarkos and Fnoteselam hospitals, Amahara region in, 2014 was 37.1%. This is almost similar to the level of nursing process implementation of this study [13]. One hundred two (51%) respondents of this study said

that irregular material supply to do nursing process affect the implementation of the nursing process. This result is supported by the study carried out in Abakaliki II teaching hospital Nigeria which is 32.7% of the respondents who said that the irregular supply of nursing process material affect nursing process implementation [8]. One hundred thirty one (83.4%) participants of this

study reported their dissatisfaction due to excessive nurse patient ratio and other reasons had affected their use of nursing process. This result is in line with a cross sectional descriptive study in Teheran, Iran show that 84.1% of participants reported that dissatisfaction of nurses due to excessive nurse patient ratio and other reasons had affected the nursing process implementa- tion. Again, this result is supported by the same study done in Addis Ababa that reported 54% of the partici- pants caring for too many patients had affected the nursing process implementation [15, 16]. In this study from the total of 12 variables involved in

the multivariate analysis; only six variables were signifi- cantly associated with P-value of <0.05 at 95% confi- dence interval. Not having consistent material supply to use the nursing process was significantly associated with the implementation of the nursing process. This result is also supported by a study done in Arbaminch Ethiopia, 2015 which reported that working in a hospital with low facility was negatively associated with the implementa- tion of the nursing process [17]. This study also highly supported the study done in

Addis Ababa and Arbaminch in selected hospitals, which found that nurses working in a stressful working envir- onment were 64.3% and 77% less likely to implement the nursing process than those in an organized working environment, when adjusting for all other factors

respectively. Similarly, in this study nurses working in a stressful atmosphere of the workplace were 99% less likely to implement the nursing process than nurses working at a positive work place environment when adjusting for all other factors [16, 17]. A stressful work- ing environment decreases the impact of nursing care to the patient by degrading the implementation of the nursing process. Highly knowledgeable nurses were 15.09 times more

likely to implement the nursing process than low knowledgeable nurses when adjusting for all other fac- tors. This results is similarly supported by the study done in Addis Ababa and Arbaminch, which reported that highly knowledgeable nurses were 38.91 and 8.78 times more likely to implement the nursing process than low knowledgeable nurses when adjusting for all other factors respectively [16, 17]. This shows that knowledge of nursing process enable for the nurses how they assess, diagnose, plan, implement and evaluate nursing practice.

Conclusion The majorities of the nurses were not implementing nurs- ing process and had not used NANDA. Similarly they had low knowledge and were only moderately skilled in nursing process implementation. Level of education, knowledge of nurses, skill of nurses, atmosphere of the workplace, short- age of material supply to use the nursing process and high patient load had statistically significant association with the implementation of nursing process.
