Background: Hypertension (HTN) is a major modifiable risk factor and the leading cause of premature deaths globally. The lack of awareness and knowledge have been identified as risk factors in low- and middle-income countries including Bangladesh. Recently, the use of mobile phone SMS text messaging is found to have an important positive impact on HTN management. Objective: The study aimed to develop awareness and knowledge in order to enhance lifestyle behavior changes among individuals with HTN in a rural community of Bangladesh by using health education and mobile health (mHealth) technology (SMS text messaging). Methods: A prospective randomized 5-month intervention, open-label (1:1), parallel-group trial was implemented among the individuals with HTN aged 35 years or older. Both men and women were included. Between August 2018 and July 2019, we enrolled 420 participants, selected from a tertiary level health facility and through door-to-door visits by community health workers. After block randomization, they were assigned to either the intervention group (received SMS text messaging and health education; n=209) or the control group (received only health education; n=211). The primary outcome was the evaluation of self-reported behavior changes (salt intake, fruits and vegetables intake, physical activity, and blood pressure [BP], and body weight monitoring behaviors). The secondary outcomes were measurements of actual salt intake and dietary salt excretion, blood glucose level, BP values, and quality of life (QOL). Results: During the study period, a total of 8 participants were dropped, and the completion rate was 98.0% (412/420). The adherence rates were significantly higher (9%) among the control group regarding salt intake (P=.04) and physical activity behaviors (P<.03), and little differences were observed in other behaviors. In primary outcome, the focused behavior, salt intake less than 6 g/day, showed significant chronological improvement in both groups (P<.001). The fruits intake behavior steadily improved in both groups (P<.001). Participants in both groups had a custom of vegetables intake everyday/week. Physical activity suddenly increased and continued until the study end (P<.001 in both groups). Both BP and body weight monitoring status increased from baseline to 1 month but decreased afterward (P<.001). In case of secondary outcomes, significant chronological changes were observed in food salt concentration and urinary salinity between the groups (P=.01). The mean systolic BP and diastolic BP significantly chronologically decreased in both groups (systolic BP, P=.04; diastolic BP, P=.02.P<.05). All of these supported self-reported behavior changes. For the QOL, both groups showed significant improvement over the study periods (P<.001). Conclusions: Based on these results, we suggest that face-to-face health education requires integration of home health care provision and more relevant and timely interactive SMS text messages to increase the effectiveness of the intervention. Besides, community awareness can be created to encourage “low-salt culture” and educate family members.

We previously performed a preliminary 6-month controlled trial to examine the effect of a disease management education program on prolongation of the time to renal replacement therapy (RRT) and/or avoidance of RRT for patients with diabetic nephropathy. However, its duration was too short to follow the changes of renal function, so we performed the present study for 24 months. This was a two-group comparative study. The intervention group received self-management education from disease management nurses and was supported by the nurses in cooperation with their primary physicians for 12 months. Then this group was followed for a further 12 months. The control group received standard care and was followed for 24 months. Of the 31 subjects enrolled in each group, 26 subjects in the intervention group and 27 subjects in the control group were analyzed after excluding drop-outs. During the study period, 0 and 2 subjects in the intervention and the control group started RRT, respectively. In the intervention group, renal function was maintained, while significant worsening was observed in the control group. Hemoglobin A1c (HbA1c) improved in the intervention group, but became significantly worse in the control group. In the intervention group, all process indicators of behavior modification increased significantly after intervention. A well-designed disease management program might be useful for maintaining renal function and improving HbA1c in patients with diabetic nephropathy. It is considered that modification of patient behavior contributed to these results.

Little is known about the actual impact of COVID-19 on caregivers of older people with dementia and resultant collaborations among them to provide continued person-centered care while undertaking infection control measures. In this study, we explored the impact of providing dementia care during COVID-19 on caregivers involved in dementia care. This is an exploratory qualitative case study. The participants were family members living with older people with dementia, care managers, and the medical and long-term care facility staff. Data were collected from 46 caregivers via face-to-face and semi-structured interviews and analyzed using thematic analysis. The interviews identified 22 themes related to the impact of COVID-19 on different positions of the caregivers involved in dementia care and their collaboration, and we categorized them into six categories. The core themes were “re-acknowledgement of care priorities” and “rebuilding of relationships.” When caregivers’ perceptions were aligned in the decision-making processes regarding care priorities, “reaffirmation of trust” and “strengthening of intimate relationships” emerged as positive changes in their relationships. Furthermore, the differences in the ability of each caregiver to access and select correct and appropriate information about COVID-19, and the extent of infection spread in the region were related to “anxiety during COVID-19 pandemic” and caused a “gap in perception” regarding infection control. The present study clarified that the process of aligning the perceptions of caregivers to the objectives and priorities of care for older people with dementia during COVID-19 pandemic strengthened the relationships among caregivers. The findings of this study are useful for caregivers involved in person-centered dementia care.

Family caregivers endure the burden of caring for patients receiving hemodialysis, which can affect their psychological status and may disrupt the care process. This study aims to assess the level of burden, anxiety, depression, and quality of life (QOL) among family caregivers, to investigate the influence of caregivers’ sociodemographic factors and patients’ clinical conditions on the level of burden, and investigate how burden affects anxiety/depression and QOL. A descriptive, cross-sectional study was conducted from September to October 2020. A total of 104 caregivers with a mean age of 44.4 ± 12.7 years (63.5% women) in the hemodialysis department of a hospital in Indonesia were examined. Zarit Burden Interview (ZBI), Hospital Anxiety and Depression Scale, and WHOQOL-BREF were used. Descriptive analysis was conducted to assess the level of psychological status, and multiple regression analysis and path analysis were performed to evaluate the association among all factors. As result, regarding burden, 10.2% had a moderate-to-severe burden, and in terms of anxiety and depression, 25% and 9.6% showed abnormal cases; the mean scores of 4 domains of QOL were about 60 points. Burden and anxiety/depression were significantly negatively associated with all domains of QOL (p < 0.001); however, sociodemographic and clinical factors were not associated with any of the QOL domains. The path analysis results showed that burden positively correlated with anxiety/depression and negatively correlated with QOL via anxiety/depression. In conclusion, family caregivers’ QOL was found to be indirectly influenced by burden through anxiety/depression. Further evaluation of clinical significance and implications for caregiver’s lifestyle regarding anxiety and depression, which result in caregiver burden, is warranted.

Background: We examined whether telecommunication-device-based distance interviews are inferior to face-to-face interviews in terms of facilitating behavioral changes and disease management in patients with diabetic nephropathy. We also examined the feasibility of a newly designed six-month telenursing program. Methods: This study represents a post-hoc analysis of data from a randomized controlled trial, in which we compared the efficacy of remote self-management education with that of direct education for patients with diabetic nephropathy. The participants were 40 company employees, who were randomly divided into two groups. Over 6 months, the intervention group (n = 21) received three distance interviews using a tablet computer. Meanwhile, the control group (n = 19) received three face-to-face interviews. In addition, both groups received biweekly nine telephone calls. A triangulation approach was used. We first compared the two groups in inferiority tests. Then, we analyzed data from semi-structured interviews with all participants and nurses, examining whether trusting relationships and motivation were developed, and the accuracy of the information exchanges. Further, for the intervention group, we also enquired about the overall operability of the telenursing device. Results: The completion rates for the program were 81.0 and 78.9% for the participants in the intervention and control groups, respectively. Both groups showed similar behavioral changes, and the participants verified the feasibility of the distance interviews. The participants in the intervention group felt that they understood the severity of their diseases and the necessity of self-management, and felt confidence in the nurses. On the other hand, their degree of behavioral change regarding self-monitoring was lower than that shown by the control group. Conclusion: Our findings show that both interview methods are effective for encouraging the adoption of self-management; further, in terms of taking medication and improving the main clinical indicators, we found that the distance method is not inferior to the direct face-to-face method. However, when considering long-term effects, based on the respective degrees of improvement in behavioral change, the direct method seems to be more effective. Trial registration: The trial was registered with the University Hospital Medical Information Network clinical trial registry (No. UMIN000026568) on March 15, 2017, retrospectively.
