Abstract

Background

Diabetes mellitus is one of the global health burdens associated with inadequate management. Self-management is a pivot of diabetes management. It has been estimated that more than one-quarter of the admissions in Nigeria hospital is as a result of diabetes complication. The study assessed nursing intervention on knowledge and skill of self-management among diabetic patients attending medical out-patient clinics in two tertiary hospitals, Ondo State, Nigeria.

Materials and methods

This study adopted a two-group, pretest-posttest quasi-experimental research design. Total enumeration was adopted for the study, where all the diabetic patients at the facility per time were recruited. One hundred and twenty-one (121) respondents participated in the study; 40 in the control group and 81 respondents in the experimental group. A self-developed questionnaire and rating scale served as the instrument for data collection on demographic information, knowledge and skill of self-management of diabetes. Data were collected over five weeks in three phases of pre-intervention, intervention and post-intervention. An educational package served as tool for the nursing intervention to enhance their knowledge and skill on diabetes self-management.

Results

Mean knowledge score of participants on self-management in the experimental group increased from 26.04 ± 2.97 to 30.57 ± 0.64 post-intervention. Mean score on skill of participants on self-management increased from 8.12 ± 7.06 to 20.77 ± 4.82 post-intervention. There was no significant increase in the mean knowledge score of the control group on knowledge and skill of self-management. There were significant differences between the pre and post-intervention mean knowledge score of participants on self-management (t = -13.72, p = 0.000) and there was also significant difference in the pre and post intervention mean skill score of diabetes on diabetes self-management in the experimental group (t = -17.01, p = 0.000).

Conclusion

Conclusively, knowledge of self-management of diabetes was moderate while participants lacked knowledge on pertinent point. Also, skill of self monitoring of blood glucose and foot care was only fair among the participants. However, the educational package utilized in this study increased the knowledge and skill of participants on self-management of diabetes. Thus the study is hoped to enhance self-management and reduce complications among participants. It is recommended that nursing intervention programmes using a well-designed diabetes self-management educational package should be included in diabetic clinics at different level of health care settings.

Introduction

Diabetes mellitus result from inadequate blood glucose regulation and other major nutrients due to absence, insufficiency or resistance of insulin [1]. It is one of the largest global health emergencies of the 21st century and among the top 10 causes of death. Every seven seconds, someone is estimated to die from diabetes or its complications, with 50% of those deaths (4 million in total per year) occurring under the age of 60 years [2]. On a global scale, diabetes hits particularly "middle-aged" people between 40 to 59 years of age which causes serious economic and social implications [3].

About 425 million people worldwide or 8.8% of adults 20-79 years are estimated to have diabetes with approximately 79% living in low and middle income countries. The number of people with diabetes may increase to 451 million if the age is expanded to 18-99 years. There is prevalence of 7.7 million (2.6-17.4%) of people with impaired glucose tolerance in 2017 and is likely to increase to 17.9 million (7.1-42.0%) in 2045 globally [2].

According to World Health Organization [4], diabetes brings a variety of complications including cardiovascular and renal complications as well as diabetes foot ulcer and impotence. Indeed, diabetes brings a lot of burden on the patients and their family including the health system [5]. Consequently it imposes a large economic burden on the global health-care system and the wider global economy [6].

Persons with diabetes require continuing medical care and self-management health promotion education to prevent complications [5]. Significantly, self-management needs to continue over time if complications incidence will be reduced and lives of patients prolonged [7]. It is therefore imperative that individuals acquire the knowledge and skills necessary to effectively manage their condition on a day-to-day basis away from professional healthcare facilities, and thereby prevent or delay the development of complications [8].

Therefore diabetes self-management education (DSME) is the course of action of enhancing the knowledge and skills, capability needed for self-management of diabetes mellitus patients; it translates to the care which is required for initiating, maintaining and reinforcing essential coping skills as well as behaviours that are involved for self-management on daily basis [9]. Diabetes self-management is crucial to keep the disease under control; it includes carrying out activities such as healthy diet, regular physical activity, self-monitoring of blood glucose (SMBG), foot care and smoking cessation. The self-monitoring of blood glucose (SMBG) and foot care requires adequate skill that can be gotten from good knowledge of these activities [10,11].

According to Jackson, Adibe, Okonta and Ukwe [7], for effective treatment of diabetes, patients must be fully involved in their management. A knowledgeable and skilful patient on self-management practices stands a positive chance to achieve and maintain glycaemic control and prevent complications. This implies that diabetes self-management education is essential and it involves an ongoing process of facilitating the knowledge, skill, and ability necessary for self-management practices.

In a review of self-management of diabetes in Africa, poor knowledge and skill was identified as one of the reasons affecting self-management. Poor knowledge could result from low literacy levels or poor understanding, which could arise from lack of education by health professionals [12].

Studies conducted on self-care practice and associated factors in western Africa revealed inadequate knowledge and skill as one of the possible reasons for poor self-management emphasizing that effective management of diabetes will be intricate without sufficient understanding of different domains of self-management of the condition [10,13]. Studies that had been carried out in Nigeria also revealed that there is poor knowledge and skill of self-management among diabetic patients and this occur in all domains, thus there is need for nursing intervention programme using educational package as a tool to reduce complications among these patients [14,15]. Hence, the need to carry out the study; nursing intervention on knowledge and skills of self-management of diabetes among patients.

Objective

The objective of the study was to assess nursing intervention on knowledge and skills of self-management of diabetes among patients attending medical out-patient clinics in two tertiary hospitals in Ondo State.

Materials and Methods

This study adopted 2 groups (experimental and control), quasi experimental research design employing purposive sampling method. Purposive sampling method was utilized because the two tertiary institutions in the states were best suited for the study. The experimental group received the intervention of interest while the control group got no intervention.

The study was conducted at University of Medical Sciences Teaching Hospital, Akure (UNIMEDTH) and Federal Medical Centre (FMC), Owo, Ondo State. Ethical clearances were obtained from the Ethics and Research Committees of both hospitals. The inclusion criteria were; patients that have been diagnosed of Type I and II diabetes who are attending the medical out-patient clinic of the selected tertiary health facilities. The exclusion criteria include Type I and II diabetic patients who were having complicated conditions like renal disease or hypertension or psychological conditions like depression. The participants in UNIMEDTH formed the experimental group with 81 participants while those in FMC formed the control group with 40 participants.

Data Collection

A structured questionnaire and self developed rating scale were used to assess the level of knowledge and skill at the pre-intervention and post-intervention phase respectively. The questionnaire had two sections, namely; Section A had 7 items that were used to collect socio-demographic data. Section B contained 31 items on knowledge of self-management. Self-developed rating scale was also used to evaluate respondents' skill on self monitoring of blood glucose and foot care. The rating scale which was an observational instrument was used to measure the above mentioned domain. It consisted of 12 responses that were rated between 0, 1 and 2. Zero score for no skill at all, 1 score for some skill and 2 for good skill. Content and face validity of the instruments was ensured by experts in education and research. The reliability of the instruments was established through an internal consistency approach. This took place in a tertiary hospital in Ibadan, Oyo State Nigeria. Cronbach Alpha of the questionnaire after the reliability was 0.706.

This study took place from May 18, 2020 to June 15, 2020. Participants were recruited using the inclusion criteria checklist. A total of 121 DM patients were recruited, 81 and 40 formed the experimental and control groups respectively. Every detail of the study was explained to participants first, those that asked questions were given appropriate answers afterwards. Nursing intervention was given to the experimental group. The same procedures were repeated for the control group except the nursing intervention.

The maximum score for correct response for knowledge on self-management of diabetes was 31; the scores are categorized as follows: Below average knowledge is scores between 0 and 10 while average knowledge scores is between 11 and 20 and above average knowledge: between 21 and 31. The maximum score for correct response for skill on self monitoring of blood glucose and foot care was 11; the scores were categorized as follows: No skill scores is between 0 and 4, some skill scores is at 5, and skilled score is between 6 and 11.

The nursing intervention was an educational package on knowledge of self-management which was conducted via face to face teaching on diet plan, physical activity, self monitoring of blood glucose and foot care, while the skill section included demonstration of self monitoring of blood glucose and foot care to the participants in the experimental group for one month after the pre-intervention phase (Supplementary).

Data Analysis

Data obtained from the study were analyzed using the Statistical Package for Social Sciences (SPSS), version 25. Descriptive statistics such as frequency counts, percentages and mean scores were used to provide answers for research questions while inferential statistics of student t-Test was used to provide answers to four hypotheses at 0.05 level of significance.

Results

Table 1 shows that about half of the respondents in both control and experimental groups were within the age 60 years and above signifying 45% and 69.1% respectively. A larger percentage of the respondents were Christians with 77.5% in the control and 90.1% in the experimental group. Majority of the respondents were married in both groups with 90% and 80.2% in the control and experimental groups respectively. Only about half of the participants (57.5%) in the control and two-fifth (34.6%) in experimental group had tertiary education. Majority of the respondents were unemployed with 77.5% and 71.1% in the control and experimental groups respectively. Only about two-fifth of the respondents in both control and experimental were employed; 40.0% and 39.5% respectively. A larger percentage of the respondents had the illness between 0-5 years in both control and experimental group; 65% and 48.1% respectively.

Post-intervention, above-average knowledge was 38 (95%) for control group and 81 (100%) for the experimental group. Only two respondents (5%) had average knowledge in the control group. The pre and post-intervention mean scores for the control group were 25.81 ± 2.58 and 25.50 ± 2.52 respectively. While for the experimental group, the pre and post-intervention mean scores were 26.04 ± 2.97 and 30.57 ± 0.64. The mean gain for the control group was -0.31 while that of the experimental group was 4.53. The maximum scores for pre and post-intervention for the control group was 30.15 and 31 for experimental. While the minimum pre-intervention score for the control group and experimental group were 19.53 and 17.84 respectively; and minimum post-intervention scores for both the control and experimental groups were 19.11 and 28.03 respectively. The ranges (pre and post-intervention) for control group were 10.62 and 9.77 respectively, while the ranges for the experimental group were also 13.16 and 2.97 respectively.

Results from Table 3 reveal that in the control group, 24 (60%), 13 (32.5%) and 3 (7.5%) patients were skilled, had some and had no skill on self-management of diabetes pre-intervention respectively. Post-intervention; 24 (60%) patients were skilled, 11 (27.5%) participants had some skill and 5 (7.5%) participants had no skill.

In the experimental group, 38 participants were highly skilled representing 46.9%, 20 participants were moderately skilled representing 24.7% while 23 respondents had low skill representing 28.4%. The post-intervention scores revealed 57 respondents representing 70.4% had high skill while 23 respondents had moderate skill and 1 respondent had low skill representing 28.4% and 1.2% respectively.

The mean scores of the control group were 13.25 ± 6.07 and 13.05 ± 6.44 pre and post-intervention and 8.12 ± 7.06 and 20.77 ± 5.28 pre- and post-intervention for the experimental group. The mean gains were -0.20 and 12.65 in the 2 groups respectively. The maximum score was 26 while the minimum score was 14 for post-intervention in the control group. Minimum scores pre- and post-intervention for the experimental group were 0 and 7 respectively, while maximum score pre- and post-intervention for the experimental group were 24 and 40 respectively. The score range for control group pre- and post-intervention were 13 and 12, and 24 and 33 for experimental group respectively.

Results from Table 4 shows 77 (95.1%) and 81 (100.0%) respondents had knowledge above average pre- and post-intervention respectively. Four (4.9%) respondents had average knowledge pre-intervention. The mean score for pre-intervention was 61.32 ± 6.99 and 71.98 ± 1.52 for post-intervention. The mean gain is 10.66. The maximum score was 73 for both pre- and post-intervention while the minimum scores were 42 and 66 post-intervention. The range score for pre- and post-intervention were 31 and 7 respectively.

Result from Table 5 shows that 38 (46.9%) respondents were skilled on self-management of diabetes pre-intervention, while 57 (70.4%) respondents were skilled post-intervention. Twenty (24.7%) respondents had some skill pre-intervention and 23 (28.4%) post-intervention. Twenty-three (28.4%) had no skill pre-intervention and only 1 (1.2%) post-intervention. The mean score for pre-intervention was 8.12 ± 7.06 and 20.77 ± 5.28 for post-intervention. The mean gain was 12.65. The maximum scores were 24 and 40 for pre- and post-intervention, and 0 and 7 for minimum score pre and post-intervention. The range values were 24 and 33 pre- and post-intervention respectively.

Discussions

A total of 121 respondents from the control and experimental groups participated in the study. Socio-demographic data revealed that about half of the respondents in both control and experimental groups were about 60 years and above representing 45% and 69.1% respectively. This result was supported by a study conducted by Marques, et al. [16] which stated that the average age range of the population in their study falls within 60-88 years. Similarly, another intervention study by Abiodun, Olaogun and Oladayo [17] also revealed that a higher proportion of the participants in the study were 65 years and above. On the contrary Olajide, et al. [18] reported that the majority of respondents were within the ages of 55 to 59 years.

Majority of the participants in the two groups were married with 90.0% and 80.2% in the control and experimental respectively. In consonance with this finding is the study from Olajide, et al. [18], where 75% of the respondents were married. In the same vein a study by Abiodun, Olaogun and Oladayo [17] showed that 67.7% and 60.1% were married in the control and experimental groups respectively.

The highest academic qualification of the participants was tertiary education; a little above half in the control group, and about one-third of the experimental (57.5% and 34.6% respectively). This is similar to findings reported by Olajide, et al. [18] with 55% having higher educational qualification and Abiodun, Olaogun and Oladayo [17] with majority of the participants having higher academic qualification with 11 (35.5%) and 12 (20.5%) in control and experimental groups respectively. Only minority of the participants do not have formal education.

About two-fifth of the participants were employed with 40% and 39.5% in the control and experimental groups respectively. However, Olajide, et al. [18], reported a different findings with majority 8 (40%) of their respondents were neither civil servants nor traders.

Notably, majority of the participants had good knowledge on diabetic diet and this is supported by Sharma and Bhandari [19] where 86% had good knowledge of diabetic plan. This is also substantiated by Kushawa, Kumari and Kushwaha [20] stating that 75% of the patients had good knowledge of diabetic diet. In contrast, Selvaraj, Ramaswamy, Radhakrishnan, Thekkur, Chinnakali and Roy [21] discovered that despite that majority (99.4%) received education on diet plan, only two-thirds of the respondents practiced it.

However, a larger percentage of the participants had poor knowledge of foot care. This is confirmed by Alshammari, Alsaid, Parameaswari, and Alzahrani [22] where 22.2% had knowledge of foot care. Similarly, a study conducted in India by Krishnan and Thirunavukkarasu [23] revealed that 75.8% had poor knowledge and did not practice self blood glucose monitoring in a proper way.

In addition, majority of the respondents had fairly good knowledge on self-management of diabetes both in the control and experimental groups pre-intervention. This differs from the findings reported by Abiodun, Olaogun and Oladayo [17] that at the pre-intervention phase, the control and experimental groups had poor knowledge of self-management. Also, at the post-intervention phase, there was knowledge gain among the experimental group, there was a significant difference in the pre and post-intervention mean knowledge score of patients on self-management of diabetes in the experimental group. This is corroborated by Farahat, Salama and Essa [24], who also reported significant difference post-intervention in the experimental with respect to intervention given. Similar studies by Olajide, et al. [18] and Abiodun, Olaogun and Oladayo [17] revealed that there was knowledge gain in the experimental group.

Less than half of experimental group and slightly above half in the control group, were skilled at the pre-intervention phase on self monitoring of blood glucose and foot care. This is in consonance with the interventional studies of Marques, et al. [16] and Abiodun, Olaogun and Oladayo [17] that participants had poor self-care practices. Farahat, Salama and Essa [24], study on foot care showed a high percentage of non-adherences to foot care parameters among respondents. Results from the pre and post intervention mean skill score in the control and experimental groups showed that there was skill gain among the experimental group as revealed by a score of -0.20 and 12.65 respectively. There was also a significant difference in the pre and post intervention mean skill score of patients on self-management of diabetes in the experimental group.

Moreover, some other studies that are not experimental were in agreement with the findings of low skill as reported by Krishnan and Thirunavukkarasu [23], where 75.8% of respondents had low skill in demonstrating self monitoring of blood glucose in a proper way. Similarly, Ajayi [25] stated that, only 17% of the respondents demonstrated self-monitoring of blood glucose. Regarding foot care, some studies revealed that respondents who had poor knowledge of foot care demonstrated poor practice of foot care as discovered by Desalu, et al. [14] and that only 10.2% of respondents had good practice of foot care. In the same vein Pourkazemi, Ghanbari and Khojamli, et al. [26] found out that 91.2% had poor practice of foot care. Similarly, another study carried out by Selvaraj, et al. [21] revealed only washing of feet were carried out by 83.3% of the respondent, all other foot care practices were less common.

Limitations

The major limitation of the study was the constraints posed on the sample size, especially in the control group due to the COVID-19 pandemic, although total enumeration of patients that attended the endocrine clinics of the two settings was utilized for the study during the time of sample collections. Hence, there was non-equivalence in the control and experimental group. Also, the study was a quasi-experimental which did not allow for randomization of the respondents.

Conclusion

The study concluded that nursing intervention on knowledge and skill is very vital in ensuring that patients are equipped to self-manage diabetes as it is one of the crucial and key components in the management and prevention of its' complications. This was demonstrated in the experimental group with improvements in knowledge and skill of self-management of diabetes among the participants post-intervention.

Implication of the Study

Self-management of diabetic patients could be achieved through effective nursing intervention. The availability of a well-designed educational package administered steps wisely to diabetic patients will foster standardized and effective knowledge based nursing intervention that will improve self-management among this population. This may also encourage further studies on factors that may enable effective nursing intervention on self management of diabetic patients.
