Patient-Support Program in Diabetes Care During the Covid-19 Pandemic: An Italian Multicentric Experience.

PURPOSE: Telephone coaching and health apps are effective means to support subjects with diabetes. Patient support programs (PSP) on type 2 diabetes are scanty, and none has been conducted in Italy. In a pilot phase, conducted during the COVID-19 pandemic, we aimed to examine the feasibility and acceptance of such program.
METHODS: The "BE THere for diabetes CARE" (BETHCARE) project is a real-world PSP conducted through telephone and digital coaching system to provide educational and emotional support to Italian adults with diabetes receiving long-acting basal insulin degludec. This pilot phase was conducted in 11 centres that enrolled a total of 63 patients (89% with type-2 diabetes). Counselors contacted patients to define a set of emotional, physical and nutritional targets, and monitoring calls were performed on a monthly basis. Data were collected on socio-demographic and anthropometric characteristics, selected clinical information, quality of life, achievement of targets and patient satisfaction.
RESULTS: Fifty-eight subjects (92%) chose to participate by telephone and 5 (8%) by mobile app. Most participants (ie, ≥80%) evaluated counselors' calls "useful/very useful", duration of calls "adequate/adequately long", were satisfied with the educational pathway and declared to be more confident in diabetes management after the program. About half of participants were confident to maintain their targets after the PSP. Achievement of nutritional targets improved during counseling, from a mean score of 1.56 at week 1 to 1.88 at week 16 (p-value = 0.03). No significant variations in the achievement of emotional and physical targets emerged. Mean patients weight decreased from 84.9 kg (week 1) to 84.3 kg (week 4) and then levelled off (84.2 kg, week 16).
CONCLUSION: This project demonstrated the feasibility and patient appreciation of a PSP in diabetes care, which is particularly important for a chronic disease of the elderly and during a pandemic period when face-to-face counseling is problematic.

Introduction

Diabetes is a considerable global chronic illness burden in ageing societies and is associated with severe long-term complications. Indeed, it is among the ten most important drivers of increasing burden of disease during the last thirty years, with a major increase in the number of disability-adjusted life-years related to diabetes, particularly in older adults.1

The number of diagnosed cases of diabetes is projected to increase substantially in the next decades.2 Consequently, the global health expenditure for patients with diabetes is expected to rise.3,4 Nonetheless, some health behaviors, as well as adequate self-management, may positively affect both the progression of existing chronic conditions, including diabetes, and their impact on the quality of life of patients. Self-management support may improve both self-efficacy and some self-management behaviors.5 NICE guidelines recommend offering structured education to adults with diabetes and/or their family members or caregivers.6 Any structured education program for adults with diabetes should be evidence-based and follow a theory-driven structured curriculum. It is important to suit the needs of patients and take into account attitudes, beliefs, knowledge and skills to self-manage diabetes.

Telephone coaching was shown to be an effective means of supporting people with chronic diseases to manage their own health, providing health knowledge and education.7 A randomized controlled trial (RCT) demonstrated the efficacy of telephone support in diabetes management.8 Besides, telephone coaching interventions may be a cost-effective strategy to support diabetic patients.9 The available evidence on the effectiveness of use of mobile health applications in Real-World diabetes programs is, on the other hand, still limited.10

To our knowledge, no patient support programs (PSP) on diabetes have been conducted to date in Italy. This pilot phase – conducted during the COVID-19 pandemic, that affected diabetic patients more severely11 – is aimed to examine the feasibility and acceptance of such program. We would highlight the massive impact of pandemic first wave in Italy, and the subsequent shortage of in-person specialists’ visit in the Diabetes Centers located all over our Country.

Materials and Methods

The “BE THere for diabetes CARE” (BETHCARE) project is a PSP conducted through telephone and digital coaching system in subjects with diabetes receiving long-acting basal insulin degludec. Its main aims are to provide educational and emotional support to Italian adults with diabetes (mainly type 2), to increase their awareness of this chronic disease and, ultimately, to improve their diet, lifestyle and overall management of diabetes. All data collected were fully anonymized. A multidisciplinary Scientific Board organized by Healthcare Network Partners Italy approved the PSP before starting the program (date: 19th November 2019) and the informed consent that was obtained from participants prior to program commencement. The project was conducted in accordance with the Declaration of Helsinki.

This pilot phase was conducted in 11 centers that enrolled a total of 63 patients. Inclusion criteria of the program are presence of diabetes and treatment with long-acting basal insulin degludec, yet to be started or already ongoing.

The scheme of the PSP is shown in Figure 1. Diabetologists and endocrinologists involved in the program presented the project to the patients. Those interested to participate registered to the PSP according to their preferred method of participation, either through the contact center of the program or via a mobile application. At this stage, they were questioned to identify their profile and to collect data on socio-demographic characteristics, anthropometric factors, selected clinical information (eg, type and duration of diabetes, HbA1c, duration of insulin treatment, severity of diabetes during previous 12 months, etc), and quality of life, including a five-item Problem Areas in Diabetes Scale (PAID-5). Subsequently, within 7 days, counselors called the patients for the first time to share their profile and define the targets: emotional, physical (eg, increase walking times, taking the stairs, achieve a certain duration of physical activity per week, etc.) and nutritional (eg, increase fruit and vegetables consumption, avoid soft drinks, improve breakfast composition, eat whole- instead of refined-grains, etc.). Follow-up information was collected on body weight and through dietary and glycemic diaries. Monitoring calls were performed on a monthly basis to evaluate the achievement of patient targets and, if needed, to agree changes in the targets. At the end of the program, final data were collected on achievement of targets, changes in quality of life scores and on several aspects related to patient satisfaction with the program, such as evaluations of the clarity and kindness of the counselor, of the number, duration and usefulness of counselor calls, of the educational materials and diaries of the program, as well as on patient feelings on confidence to manage the disease and maintain lifestyle targets after the end of the counseling period.

Statistical Methods

Descriptive analyses were conducted by tabulating frequencies and percentages for categorical variables and mean, median values, standard deviations (SD) and interquartile ranges (IQR) for continuous variables. Achievement of nutritional, physical and emotional targets was registered using a scale ranging from 0 (target not achieved at all) to 3 points (target fully achieved). Comparisons between values at week 16 and at the start of the program (week 1) were performed by using the paired t-test or the corresponding Wilcoxon signed-rank test, after checking whether data were normally distributed (based on the Shapiro–Wilk statistic). Two-sided p-values < 0.05 were identified as statistically significant, but were only considered as exploratory results. All analyses were conducted using SAS version 9.4 (Cary, NC, USA).

Results

Table 1 shows the main socio-demographic characteristics of subjects enrolled in the project. The median age at enrolment was 57 years (IQR=15.2), with 17% of subjects aged 70 years or more. Fifty-eight percent of subjects were males, and the majority of patients lived in southern (44%) or northern (40%) Italy. Education degree was primary school for 19%, secondary school for 41%, high-school degree for 33% and university degree for 6% of subjects. Mean body mass index at baseline was 30.2 (SD=7.5; median=28.8) kg/m2, with 41% of patients reporting a BMI above the WHO obesity threshold of 30 kg/m2.

Self-reported clinical and other disease-related characteristics of patients are given in Table 2. Most subjects had type II diabetes (89%) and used concomitant drug treatment for non-diabetic conditions (86%). Thirty-eight patients reported HbA1c above 8.5%, and 34% reported a short duration of insulin treatment of less than one year. With reference to diabetes control in the year before enrolment in the project, 43% of patients self-reported at least one episode of hypoglycaemia and 8% reported hospitalization due to diabetes.

Table 3 gives general information on contacts between counselors and patients during the PSP. The first call of counselors, aimed to take the patient in charge and to agree the objectives, had a duration on average of 25.0 minutes (SD=12.6). A total of 220 monitoring calls were performed during follow-up, with a mean of 3.5 calls per patient (SD=1.7) and an average duration of 18.2 minutes (SD=8.3). The median duration of follow-up was 131 days (25–75% percentiles: 58–156 days).

Table 4 reports information on patient satisfaction at the end of program, separately for those participating by telephone contacts and by mobile app. Fifty-eight out of 63 subjects (92%) chose to participate through telephone contacts and 5 (8%) by app. Most participants evaluated counselors’ calls “useful” or “very useful” (91% of telephone participants, 100% of app users), duration of calls “adequate” or “adequately long” (98% by telephone, 80% by app), were satisfied with the educational pathway of the PSP (88% by telephone, 100% by app) and declared to be more confident in diabetes management (93% by telephone, 80% by app). About half of the participants were confident to maintain their targets after the end of the program (50% by telephone, 40% by app).

Figure 2 shows the achievement of emotional (Panel A), physical (Panel B) and nutritional (Panel C) targets after 1, 8 and 16 weeks of the program in 34 patients with at least 16 weeks of follow-up. No variations in the achievement of emotional objectives emerged during the program, with mean scores of 1.56 at week 1, 1.53 at week 8 and 1.53 at week 16 (p-value=0.96). The mean score for achievement of physical targets was low at weeks 1 and 8 (equal to 1.09 and 0.94, respectively), increasing to 1.35 at week 16 (p-value=0.15). Achievement of nutritional targets improved during counseling, from a mean score of 1.56 at week 1 to 1.88 at week 16 (p-value=0.03). When all 63 participants were examined, the latter results were materially unchanged (scores of 1.57 and 1.88 at weeks 1 and 16, respectively).

Discussion

This project conducted during the challenging period of COVID-19 pandemic reported a successful participation to a PSP in diabetes care and favorable patient satisfaction at the end of the program. Achievement of nutritional targets increased during the program, indicating a favorable role of patient counseling in the management of everyday lifestyle in this chronic disease. Notwithstanding the stressful time-frame - ie, most patients participated during the first national lockdown in Spring or during the second COVID-19 outbreak in Autumn 2020, with several studies showing the high distress experienced by patients with chronic diseases, elderly and other risk groups during the pandemic12–14 - the mean weight of enrolled diabetes patients tended to decrease during the first month of counseling, and to level off subsequently. In a recent survey on dietary habits and changes during the COVID-19 lockdown in Italy, a large portion of subjects reported positive weight modification, as well as physical activity reduction for nearly 70% of responders.15

Several studies were conducted to assess whether telephone coaching effectively improved health outcomes in patients with diabetes. However, most programs were conducted in patients with type 1 disease, whereas evidences for type 2 diabetes are still relatively limited. In a randomized controlled trial of patients with type 2 diabetes, Pro-Active Call Center Treatment Support (PACCTS) facilitated improvements in glycemic control.8 This was also well-accepted by users, who considered it a satisfactory service that made them more knowledgeable and more confident in their ability to manage and control their diabetes and general well-being.16 Other evidence comes from the Get Healthy Information and Coaching Service (GHS), an effective 6-month healthy lifestyle coaching service including a specific prevention module focused on subjects at increased risk of type 2 diabetes.17 This showed that a telephone-delivered program may be beneficial in promoting weight reduction and improvements towards healthy lifestyle behaviors. These results were comparable with other diabetes prevention lifestyle programs, indicating that telephone coaching may be a suitable intervention. Furthermore, in a recent community-based, randomized, controlled trial, 365 adults with type 2 diabetes mellitus were assigned to either usual diabetes education (n=177) or diabetes health coaching (n=188) plus diabetes education intervention to evaluate changes in A1C after 1 year and, as secondary outcomes, the evolution of quality of life scores and self-care behaviours. Diabetes health coaching plus diabetes education reduced A1C by 0.49% more than diabetes education alone and improved quality of life scores.18 In line with previous randomized studies,19,20 our project provides additional information on the feasibility and effectiveness of PSP in type 2 diabetes, in a Real-World setting.

There are several different ways to provide support to patients. New technologies and way to think traditional PSP may offer effective and more convenient alternatives to manage diabetic patients. Indeed, telemedicine is an effective and well accepted means of providing diabetes education to patients.21 Also, digital-based programs combined with human coaching were found to decrease chronic disease risk.22 Digital Health technology has developed rapidly, and health apps have become increasingly common in diabetes care and self-management. Overall, mobile phone applications may be a useful tool for improving self-management and perceptions of self-efficacy in people suffering from diabetes.23 Furthermore, telemedicine had a key role to assist diabetic patients during the COVID-19 pandemic, especially in lockdown periods.24,25 In the present project, provided that counseling was given to all participants by telephone calls, patients were given the opportunity to choose between a health app or a traditional approach (based on telephone contacts and a kit of materials) for their registration, data collection and final questionnaire. More than 90% of subjects, however, decided to participate through telephone, mainly because they preferred to interact with a person. The generally low educational status of participants, their relatively high age and the concomitant COVID-19 pandemic may, at least in part, explain the preference towards telephone. Telephone contact could, in fact, prevent patients from feeling alone in dealing with their disease during this challenging period. The large preference directed to telephone contact is in any case in line with previous concerns expressed on barriers to overcome for the use of health apps in education programs and self-management of chronic diseases, including poor usability resulting from technological issues, inadequate internet access, lack of awareness and health literacy issues.10,23,26

An important limitation of this project is its small sample size. However, this was a pilot phase aimed at evaluating the feasibility of the PSP in an Italian multicentric project. In this context, in order to improve the PSP, we carefully considered the reasons of patients who left the program early or were not fully satisfied with the educational pathway, and we identified two main groups of subjects: i) those who were already adequately informed on diabetes and its management, and thus considered the program not particularly useful; ii) those who reported that, during the program, diabetes was a less important problem as compared to other urgent health issues (mainly the COVID-19 pandemic). These aspects will be kept in due consideration in the future. Among other limitations, the uneven distribution of subjects choosing to participate by app vs telephone contact did not allow meaningful comparisons of program feasibility and patient satisfaction between groups. The observational nature of the project implies a lack of randomization of subjects and the possible occurrence of selection and information bias. Still, Real-World projects are important to confirm in a real-life setting (effectiveness) the results previously obtained in RCTs on the efficacy of interventions. Strengths of the program are its nationwide setting (with centers participating in northern, central and southern Italy) and the focus on type 2 diabetes, for which PSP are relatively infrequent.

Conclusion

This project demonstrated the feasibility and patient appreciation of managing a PSP in diabetes care via telephone, which is particularly important for a chronic disease of the elderly, especially for patients on insulin therapy, and during a pandemic period when face-to-face counseling is problematic.
