Nurses Practice and Associated Factors towards Hemodialysis Care in Addis Ababa, Ethiopia

,


INTRODUCTION
Hemodialysis (HD) is an extracorporeal therapy that is prescribed to reduce the signs and symptoms of uremia and to substitute the partial functions of the kidneys [1].It is the process of cleansing the blood from accumulated waste products.The process happens through the bidirectional movement of particles across a semipermeable membrane.Clinically, this movement takes place in and out of blood, across a semipermeable membrane.If the blood is exposed to an artificial membrane outside of the body, the process is HD [2].
HD has existed for more than 50 years and has prolonged the lives of millions of patients with renal failure worldwide.Although the fundamental principles of HD are still applying today, dialysis technology has technologically advanced markedly [3].It is rapidly becoming more widespread as it has the potential to dramatically make better the quality of life and survival rate of chronic dialysis patients [4].Regardless of many technical improvements in medical care and dialysis delivery that over the last few years, mortality and morbidity rates keep on high and the quality of life of uremic patient is still deprived and there are still important acute complications that had faced by nurses responsible for patients receiving HD in both acute and chronic clinical settings [5].
Generally, Complications of hemodialysis can be divided into two major groups: Treatment-related medical complications: Those are frequent intradialytic complications, these (in order of frequency) include hypotension, muscle cramps, nausea and vomiting, flushing of the face, headache, increased pruritus, chest pain, fever, and chills.The other is Machine-related complications: These complications are due to accidents or failure of safety mechanisms of hemodialysis treatment.They include air embolism, hemolysis, hyperthermia or hypothermia, blood loss, and conductivity problems [6].The complications of hemodialysis are due to the disease itself as well as the mode of renal replacement therapy (RRT) [6].Hemodialysis remained the most common treatment modality, with approximately 1,929,000 patients undergoing hemodialysis, for 89% of all dialysis patients.In Egypt, the total prevalence of patients on dialysis is 264 per million [7].The incidence and prevalence of endstage organ failure in Ethiopia, including those of end-stage renal disease, are not known [8].
Quality has become an increasingly predominant part of our lives.The patient is constantly looking for quality care and services [9].In nursing care of hemodialysis patients, quality is a complex concept that has multiple perspectives including the technical and personal aspects also; it should be conforming to standards of care, which are considered as a starting point for better practice.A patient undergoing hemodialysis procedure requires specially trained staff and special nursing care during phases of dialysis and the termination phase [10].When appropriate dialysis care is available early in the course of management, the potential for better health improves, and that patient can remain active in family and community life [11].Nurses are responsible for the direct care of patients undergoing dialysis.Dialysis nurses must have knowledge and skills because they reflected vital features of quality nursing care in the hemodialysis treatment [12].Little is known about the nurses' practice and associated factors while caring for patients undergoing hemodialysis in Ethiopia.The current study was aimed to determine level of practice and associated factors of hemodialysis among nurses.

METHOD AND MATERIALS
This study was conducted in Addis Ababa, the capital city of Ethiopia.The city has a subtropical highland climate.
According to the 2017 estimation, Addis Ababa has a population of 6.6 million people.The city has 52 hospitals, of which 13 are public and 39 Private.Currently, there are 30 hemodialysis centers with a total of 186 hemodialysis chairs and approximately 800 patients on hemodialysis.Four of them are governmental dialysis units, with 31, 7, 5, and 3 hemodialysis chairs available in St. Paul hospital millennium medical college, Minillik II memorial hospital, Zewuditu memorial hospital, and Tikur Anbesa hospital respectively.
An Institution-based cross-sectional study was carried out on hemodialysis care provider nurses from all governmental hospitals dialysis units situated in Addis Ababa, Ethiopia from March 2020 to May 2020.A total of 62 nurses were included in the study.
A structured self-administered questionnaire was utilized to collect the data.Data were collected on different socio-demographic and other pertinent variables used to determine the practice of nurses regarding hemodialysis care.The mean score was utilized as a cut of point to describe the nurse's practice regarding hemodialysis care.A supervisor and two data collectors, who had a B.Sc. degree in nursing, were recruited to assist in the data collection process.Training was given for the supervisor and data collectors on the objectives of the study, the questions, and extent of explanations, the way to keep privacy and confidentiality and other ethical issues.The principal investigator was checked and reviewed the completeness of questionnaires and offered the necessary feedback for the supervisor and data collectors at spot to prevent bias.Data was checked for its completeness; then coded and entered into Epi Data 4.62 version.Finally, data was exported to SPSS version 25.0 for analysis.Categorical variables were presented using frequency with percentages, while quantitative variables were presented in medians with standard deviations.Bivariate regression analysis was done to identify candidate variables for the final model.Multivariate regression analysis was conducted to determine the association between dependent and independent variables.Adjusted odds ratio with 95% confidence interval was used to report factors associated with the outcome variable, considering P <0.05 to declare statistical significance.

RESULTS
In this study, among 62 nurses working in different haemodialysis centres in Addis Ababa governmental hospitals, 60 nurses were participated with the response rate of 96.7%.Majority of participants (70%) were females, and the mean age of the respondents was 29.6±4.12years.Regarding educational background of the participants, 93.3% of them were BSc holders followed by 5% master's degree (Table 1).In the current study, it was reported that 65% of nurses working in the dialysis room of governmental hospitals in Addis Ababa had good practice, followed by 35% of them having poor practice (Table 2).In this study, 60% of nurses working in dialysis unit of hospitals had taken training regarding dialysis procedure and intradialytic complication management, and 66.6% of the nurses who had taken the training reported that they were satisfied by the training (Table 3).

Practice related Factors of Nurses towards Hemodialysis
In the bivariable logistic regression analysis, experience of nurses, training of nurses regarding hemodialysis, knowledge of nurses, presence of patient assessment guideline, presence of AV-fistula assessment form was associated with the practice of nurses.Those variables that have a p-value less than or equal to 0.25 were entered

DISCUSSION
This facility based cross sectional study was conducted to assess practice and associated factors regarding hemodialysis care among nurses.Among the participants, the majority (70%) were females, which shows the dominance of females over the males.The mean age of the respondents was 29.6 ± 4.12 years; shows that the newly graduate and expert nurses were interested to the hemodialysis care practice.These findings were similar to the study done in USA, found that the most respondents in their study were young age [13].
The majority (93.3%) of participants had bachelor's degree and 5% had masters and only 1.7% diploma; this is due to the fact that people are upgrading themselves and majority of the participants were from teaching and tertiary hospitals that were administered by university, since the university criteria to be recruited is bachelor degree holders.
In this study, it was reported that 65% of nurses working in the dialysis care had good practice, followed by 35% of nurses had poor practice.A study conducted in Saudi Arabia reported that 84.13% of participants had good practice, which is higher than our finding [13].Similarly, results from a study conducted in Khartoum, Sudan reported that 78% of nurses had good practice.However, a study finding in Brazil reported that 47.54% of nurses had good practice which is by far lower than our finding [5].These differences may be due to variation in In this study, nurses who had 4 years and above experience in working dialysis unit were 11 times more likely to have good practice compared to those who had less than 4 years' experience.This finding is supported with the results of study conducted by Hosien Shahdadi and Mozhgan Rahnama that the nurse's experience had positive effect on the outcome of patients within hemodialysis [14], and other study conducted in Iran supports the this finding [15].This is because experience improves the confidence, protection, and to gain patients' trust and ensure a successful dialysis through adaptation of practice of care.
In the current study, we found that nurses who took training regarding hemodialysis were 8.5 times more likely to have good practice compared to those who did not took training regarding hemodialysis care.This finding was agrees with the results of studies done in Iran [15] and Saudi Arabia [16].This is because of provision of specialized training for nurses improve their skills to manage complication and prevent infections.
In this study, nurses who were knowledgeable regarding hemodialysis were 12 times more likely to have good practice compared to those nurses who were not knowledgeable.This finding was in line with the results of studies conducted in Iran (Iran), Saudi Arabia [16] and Jordan [17].The possible justification could be as nurses gain basic knowledge on hemodialysis to provide high quality care, may take advantage of their technical knowledge.

LIMITATION OF THE STUDY
The current study could not establish cause-effect relationship given that it was a cross-sectional study.Use of small sample size was also another limitation of the study that may affect the generalizability of the study finding.

CONCLUSION
In the current study the practice of nurses towards hemodialysis care was good.The year of experience, having getting training and their level of knowledge had shown significant association with practice among nurses on hemodialysis care.Interventions should focus on providing training and recruiting experienced nurses with good level of knowledge on hemodialysis care to maintain and improve patient's health status.
