Background: Older adults who receive hemodialysis face different physiological and psychosocial stressors. Management of physiological and psychosocial stressors is among their basic needs for a desirable life.
Objectives: This study aimed to evaluate the effects of telephone-based telenursing on perceived stressors among older adults receiving hemodialysis. Methods: This quasi-experimental study was conducted in 2018 on sixty older adults who were receiving hemodialysis. Participants were conveniently recruited from the hemodialysis centers of Shahid Beheshti and Imam Khomeini hospitals, Babol and Behshahr, Iran, and were randomly allocated to a control and an intervention group. A 3-month telephone-based telenursing program was implemented for participants in the intervention group. Physiological and psychosocial stressors were assessed before and after the study intervention. Data were analyzed using the Chi-square, paired-samples t, and independent-samples t-tests. Results: The mean score of physiological stressors in the intervention group statistically significantly reduced from 17.33 ± 1.74 at pretest to 11.96 ± 3.16 at posttest (P < 0.001), whereas it statistically insignificantly changed in the control group from 17.30 ± 1.66 to 17.16 ± 3.03 (P = 0.747). Moreover, the mean score of psychosocial stressors in the intervention group statistically significantly reduced from 57.80 ± 8.17 at pretest to 32.53 ± 5.84 at posttest (P = 0.001), but statistically insignificantly changed in the control group from 61.2 ± 9.03 to 62.53 ± 6.04 (P = 0.416). Although the between-group differences respecting the pretest mean scores of physiological and psychosocial stressors were not statistically significant (P > 0.05), there were significant between-group differences respecting the posttest mean scores and the pretest-posttest mean differences of both physiological and psychosocial stressors (P < 0.05). Conclusion: Telenursing is effective in significantly reducing perceived stressors among older adults receiving hemodialysis. Nurses can use telenursing to reduce stressors among this patient population.

| Introduction|| |
End-stage renal disease (ESRD) is among the major health problems in the world. It is most common among older adults. In most countries, 40% of patients with ESRD age more than 65.
Patients with ESRD need renal replacement therapy for life. Hemodialysis is one of the most common renal replacement therapies., Hemodialysis relieves ESRD symptoms and improves survival; but, it does not treat ESRD and patients suffer from a wide range of symptoms, problems, and stressors related to both ESRD and hemodialysis.
Stressors among patients receiving hemodialysis can be divided into two main categories, namely physiological and psychosocial stressors., Physiological stressors among these patients include factors such as fatigue, arteriovenous complications, nausea, loss of bodily functions, coagulopathy, and joint stiffness, whereas psychosocial stressors include factors such as frequent hospital admissions, treatment costs, limited time and place for rest and comfort, and limitations of physical and social activities., A study reported that patients with hemodialysis suffer from more psychosocial stressors than physiological ones. These stressors can not only affect the patients' physical and mental health, but would also interfere with their familial and social relationships, lifestyle, employment, and quality of life.
There are different strategies for stress management, the choice of which depends on patients' own personal beliefs, experiences, support systems, and available resources. Telenursing is one of these strategies., As an easily accessible intervention, telenursing mainly focuses on promoting health, well-being, and self-management. Telenursing interventions can be both educational and behavioral and can be used for both control and follow-up. The main positive outcomes of telenursing are easy access to health-care providers, time and resource management, self-care promotion, symptom management, family support, empowerment of family caregivers, and patient comfort and safety improvement, mainly in remote and low-income areas. Telenursing enables nurses to access patients in remote areas and manage health-care services based on their medical history. Telenursing uses technologies such as telephone, computer, tele-monitoring, and the Internet for nurse–patient communication. Telenursing through telephone is a simple, safe, and economical intervention with great popularity in different countries, which can be used for health promotion.
Most primary telenursing-related studies were conducted in developed countries, though telenursing is currently a main research priority in different countries. Different studies reported the positive effects of telenursing among different patient populations.,,, However, there is limited information about the effects of telenursing on the stressors of patients receiving hemodialysis. Therefore, further studies, particularly in developing countries and on elderly population, are needed to determine the challenges and outcomes of telenursing. The present study was conducted to address these gaps.
This study aimed to evaluate the effects of telephone-based telenursing on perceived stressors among older adults receiving hemodialysis.
| Methods|| |
Design, setting, and participants
This single-blind, quasi-experimental study was conducted in 2018 on sixty older adults who were receiving hemodialysis. Participants were conveniently recruited from the hemodialysis centers of Shahid Beheshti and Imam Khomeini Hospitals, Babol and Behshahr, Iran. Inclusion criteria were agreement and consent for participation, access to home telephone, age more than 60, no hearing or speech impairment, hemodialysis for at least 3 months, no history of kidney transplantation or stressful life events (such as significant losses) in the past 6 months, no affliction by psychological disorders (determined by a score of 8 or more for the Abbreviated Mental Test), ability to perform daily activities (determined by a score of 12 or more for the Activities of Daily Living Scale), and a score of <71.6 for a hemodialysis need assessment questionnaire. The participants were randomly allocated to a control and an intervention group through block randomization with ten-person blocks. They were excluded if they were reluctant to stay in the study, experienced death, faced serious physical or psychological crises, were hospitalized, had more than one absence from the sessions of the study intervention, received kidney transplant, migrated to remote areas, and were not accessible by telephone for 2 weeks during the 1st month or for 3 weeks during the 2nd and the 3rd month of the study intervention. All participants were blind to the study groups.
The sample size was estimated based on the findings of a former study, in which the mean and standard deviation of overweight (as a stressor) in the intervention group has been changed from 2.94 ± 1.0 to 2.33 ± 0.64. Then, with a Type I error of 0.05, a Type II error of 0.20, a σ1 of 1.0, a σ2 of 0.64, a μ1 of 2.94, and a μ2 of 2.33, the sample size was estimated to be 30 per group.
Data collection instruments
Data collection instruments were a demographic questionnaire, a hemodialysis need assessment questionnaire, and the Hemodialysis Stressor Scale. The items of the demographic questionnaire were on participants' age, gender, income adequacy, employment status, marital status, second marriage, place of residence, and insurance coverage. The Hemodialysis Stressor Scale was developed based on Baldree and colleagues' studies in 1982 and includes 6 items on physiological stressors and 22 items on psychosocial stressors. The items are responded on a 5-point scale from 0 (no stress) to 4 (severe stress). Accordingly, the total scores of physiological and psychosocial stressors can be in the range of 0–24 and 0–88, respectively. Higher scores are interpreted as greater levels of stress. This scale has a Cronbach's alpha value of 0.89, and its Farsi versions has been used in a former study in Iran. The hemodialysis need assessment questionnaire was developed based on an existing educational need assessment questionnaire for patients with hemodialysis. It includes 29 items on patients' educational needs. The items were scored on a Likert-type scale from 0 to 4, resulting in a total score of 0–112. The total score was interpreted as follows: 0–37.3: dependent; 37.3–74.6: semi-dependent; and 74.6–112: independent. Participants with scores <74.6 were included in the study. In the present study, the content validity of the Hemodialysis Stressor Scale and the hemodialysis need assessment questionnaire was assessed by ten faculty members of Fatemeh Zahra School of Nursing and Midwifery, Ramsar, Iran. The Cronbach's alpha values of these questionnaires were 0.88 and 0.62, respectively.
The study intervention was implemented in the following two steps:
Step 1: Depending on participants' learning capacity, two to three educational sessions on ESRD and hemodialysis were held for all of them in both groups. The participants attended the sessions in ten-person groups. The participants in each session were equally and randomly selected from both control (n = 5) and intervention (n = 5) groups in order to reduce potential biases. The date and the length of each session were determined according to participants' preferences, age, and conditions. [Table 1] shows the content of the sessions. Education to each group of participants was provided in two 50-min lecture sessions with a 15-min interval and using an educational booklet prepared based on leading textbooks and resources. Sessions were held in the conference rooms of the study setting. Besides education, several hemodialysis-related scenarios were provided to the participants and they were asked to discuss them based on the provided educations. At the end of the last session, an educational pamphlet was given to each participant.
Step 2: In the second step, follow-up telephone contacts were made with participants in the intervention group for 12 successive weeks. Contacts were made twice weekly in the first 6 weeks and once weekly in the second 6 weeks. The length of the contacts varied between 15 and 20 min according to the participants' needs. The time of the contacts was arranged between 09:00 and 21:00 according to participants' preferences. All contacts were made using a single telephone number. Contacts were related to patients' general health status and their educational needs and were guided using a checklist of their educational needs. During each contact, the participants were encouraged to adhere to medical and nursing recommendations and at the end, an appointment was made for the next contact. Participants could also contact us to ask their questions. The content of each contact was documented to arrange the content of the next contacts. Participants in the control group solely received face-to-face education without any follow-up telephone contact.
Before the first step and 3 days after the 3-month follow-up period, the Hemodialysis Stressor Scale was completed for each participant in the conference room of the study setting while he/she was not under hemodialysis.
This study was approved by the Ethics Committee of Babol University of Medical Sciences, Babol, Iran (code: MUBABOL.HRI.REC.1396.124). Necessary permissions for the study were obtained from the authorities of Fatemeh Zahra School of Nursing and Midwifery, Ramsar, Iran, and provided to the authorities of the study setting. The aims of the study were explained for participants, and their written informed consents for participation were secured. All the participants were free to stay in or voluntarily withdraw from the study, and they were ensured that their data would remain confidential.
The study data were analyzed using the SPSS software version 16.0 (SPSS Inc., Chicago, IL, USA). The measures of descriptive statistics (including frequency, mean, and standard deviation) were used for data summarization. Between-group comparisons respecting categorical and numerical characteristics of participants were made using the Chi-square and the independent-samples t-tests, respectively. Moreover, within- and between-group comparisons respecting their mean scores of stressors were made using the paired and the independent-samples t-tests. P < 0.05 was considered statistically significant.
| Results|| |
Sixty older adults receiving hemodialysis participated in this study in a control and an intervention group [Figure 1]. The age means in these groups were 74.20 ± 8.01 and 72.67 ± 7.73, respectively. There were no statistically significant differences between the groups respecting participants' age, gender, income adequacy, education level, marital status, employment status, and educational needs [P > 0.05; [Table 2].

The results of the paired-sample t-test showed that in the intervention group, the mean scores of the following psychosocial stressors statistically significantly reduced after the intervention: limitations of food and fluids, length of treatment, ineffective role performance, reversal of family roles with spouse, frequent hospitalizations, dependence on health-care providers, limitations in the styles of clothing, treatment costs, changes in family responsibilities, uncertainty over future, reduced social activities, dependence on others, occupational problems, limitation of physical activities, and limitation of recreational activities (P < 0.05). Similarly, the mean scores of the following psychosocial stressors statistically significantly reduced in the control group: length of treatment, changes in body appearance, occupational problems, limitation of physical activities, and limitation of recreational activities (P < 0.05). Moreover, respecting physiological stressors, the mean scores of the following stressors statistically significantly reduced in the intervention group: muscular pain or cramp, joint stiffness, arterial and venous punctures, nausea and vomiting, and fatigue (P < 0.05).
The results of the paired-sample t-test illustrated that while the total mean scores of physiological and psychosocial stressors did not significantly change in the control group (P > 0.05), both scores significantly reduced in the intervention group [P < 0.05; [Table 3]. Consequently, the independent-sample t-test showed that although the between-group differences respecting the pretest total mean scores of physiological and psychosocial stressors were not statistically significant (P > 0.05), the posttest mean scores of physiological and psychosocial stressors in the intervention group were significantly less than that of the control group (P < 0.05). Moreover, there were statistically significant between-group differences respecting the pretest-posttest mean differences of both physiological and psychosocial stressors [P = 0.001; [Table 3].

| Discussion|| |
The findings showed that need-based education and follow-up through telenursing significantly reduced the mean scores of both physiological and psychosocial stressors. A former study also showed that education promoted healthy behaviors among patients receiving hemodialysis. Besides behavior improvement, need-based education can also reduce health-care costs, improve care quality, reduce dependence, and thereby, reduce the effects of stressors and improve health.
The study findings also showed that telenursing significantly reduced physiological stressors such as fatigue, muscular pain, joint stiffness, nausea and vomiting, and arterial and venous punctures. We could not find any similar study into the effects of telenursing on stressors among patients receiving hemodialysis for the purpose of comparison. However, in line with our findings, several studies reported that telenursing was effective in reducing pain among cancer patients; pain and joint stiffness among patients with inflammatory rheumatic diseases; nausea and vomiting among patients with multiple sclerosis; and fatigue among patients with chronic conditions such as chronic obstructive pulmonary disease, diabetes mellitus, and amyotrophic lateral sclerosis. Telenursing provides the opportunities for continuous patient assessment, early problem detection, and effective problem management. In the present study, regular telephone contacts helped us assess participants' needs and provided need-based recommendations. Moreover, participants could contact us to ask their questions. These strategies helped reduce the effects of stressors.
Our findings also showed the insignificant effects of telenursing on itching. Contrarily, a study showed that telephone-based follow-up relieved itching among burn patients. This contradiction is attributable to the differences in the causes and the mechanisms of itching in patients with burn injuries and patients receiving hemodialysis. Itching among patients receiving hemodialysis is a multifactorial problem caused by a wide variety of factors such as diet, uremia, high level of phosphorus, low level of calcium, hyperparathyroidism, and allergic reaction to heparin and ethylene oxide used to sterilize dialysis machine. Such complex and multifactorial mechanism of itching among patients receiving hemodialysis requires long-term telenursing interventions for effective itching management. We also found that our telenursing intervention was effective in significantly reducing psychosocial stressors such as loss of social activities, fear over loneliness, dependence on others, and financial problems. In line with our findings, previous studies also reported that telenursing significantly reduced psychosocial problems among patients receiving hemodialysis., Given the multiplicity of ESRD- and hemodialysis-related problems, older adults receiving hemodialysis always need such interventions for the effective management of their problems. Our findings showed that primary education complemented by follow-up telephone contacts had significant positive effects on stressors in the intervention group.
This study had some limitations. Patients' physical and psychological conditions might have affected their answers to the study questionnaires. Moreover, educations were provided based on the results of need assessment performed only before the intervention. Of course, we attempted to circumvent this limitation through assessing the participants throughout the study using checklists. Moreover, factors such as age, gender, and small sample size might have affected the study findings. Therefore, further studies with larger samples are recommended to compare the effects of telenursing among patients from different genders and age groups.
| Conclusion|| |
This study suggests that simple short-term education has significant positive effects on patient outcomes among patients receiving hemodialysis. While providing patient education, nurses need to pay careful attention to patients' educational needs and perform follow-up assessment to ensure the effective fulfillment of their needs. Telephone-based telenursing is a sample strategy to maintain the continuity of patient education and care. However, further studies and efforts are still needed in our countries in order to make telenursing practical. Nurses' active engagement in telenursing can reduce patients' stress and thereby, reduce their request for health-care services.
