Conclusion: The study underscores the positive impact of telepharmacy on drug interaction detection and glycemic control among Indonesian diabetics.
Drug interaction, glycemic control, telepharmacy, pharmacist, diabetes management
Diabetes management faces many interrelated challenges, particularly polypharmacy, where the intricate nature of diabetes prompts the concurrent use of multiple medications (
In diabetes management, pharmacists play a crucial role in optimizing the appropriateness and safety of treatment regimens (
However, pharmacists face several constraints that limit their ability to provide comprehensive care. Having multiple responsibilities, such as medication dispensing, administrative tasks, and managing high patient volumes, limits time for engagement in patient education and counseling (
To overcome these constraints, telepharmacy is revolutionizing diabetes care. Digital platforms centralize patient data, providing pharmacists with comprehensive information to conduct thorough medication reviews and detect interactions (
Telepharmacy emerges as a promising innovation bridging gaps in healthcare delivery, including diabetes management (
Therefore, this study aimed to address this gap by introducing a novel telepharmacy application specifically tailored for diabetes care. Through its development and preliminary evaluation, this study aimed to determine whether this intervention can significantly improve drug interaction detection and glycemic control among Indonesian diabetes patients. This exploration holds the potential to revolutionize diabetes care paradigms in Indonesia and offers a proactive solution to the challenges encountered in conventional diabetes management approaches.
This study adhered to the reporting guidelines outlined in the STROBE statement (
We partnered with an information technology developer (Indonesia Test & Telepharmacy or InaTTI) to pioneer the development of a telepharmacy application tailored for diabetes patients. For the drug interaction checker, we initially established the anti-diabetes medication based on Indonesia’s diabetes therapy guidelines, specifically the Guidelines for Management and Prevention of Type 2 Diabetes Mellitus in Adults in Indonesia Year 2021. We searched https://cekbpom.pom.go.id to verify the availability of these anti-diabetes drugs. Subsequently, these anti-diabetes medications were assessed for potential drug interactions, their effects, severity levels, and recommendations for managing these effects using available drug interaction checker applications such as Drugs.com, Micromedex, and Drug Bank.
Once the database was organized, we integrated the drug interaction checker with the InaTTI telepharmacy application. This telepharmacy application is already linked to the patient medication record and patients’ WhatsApp accounts. Consequently, whenever we input the names of anti-diabetes medications and other drugs from a prescription, the telepharmacy application promptly notifies us about potential drug interactions, their effects, severity levels, and recommended ways to manage these interactions. Moreover, the telepharmacy application sends notifications to patients via WhatsApp, prompting them to engage in counseling sessions through telepharmacy.
This was an observational before-and-after study conducted at Muhammadiyah Hospital, a private secondary care hospital located in the capital of the most populous province in Indonesia. We prospectively studied prescriptions among type 2 diabetes (T2D) patients in the Prolanis program. Prolanis is an integrated health service initiative, which aimed to manage clinical and laboratory outcomes, prevent complications, and enhance the quality of life for patients with diabetes and hypertension (
This study examined changes in outcomes following the use of a digital product designed to manage health conditions (
The inclusion criteria were prescriptions of T2D patients aged 18 or older who sought outpatient treatment. Employing a total sampling method, we focused to emphasize potential drug interactions within polypharmacy scenarios. Therefore, prescriptions with fewer than five drugs were excluded (
The Research Ethics Committee of the University of Padjadjaran approved this study (No. No.195/UN6.KEP/EC/2023). Written informed consent was obtained from all patients. We ensured their privacy and anonymity during data collection and analysis.
In the before-telepharmacy group, we prospectively examined the prescriptions of eligible patients before the implementation of the telepharmacy application (April 2023). During this phase, potential drug interactions were manually identified using Medscape, and medication was dispensed according to standard procedures. Counseling in this group was given using the conventional (a one-to-one offline) method. In May and June 2023, we collected data on patients’ FBG levels. We collected this data only twice because, in the subsequent months, Prolanis patients were typically referred back to primary care facilities. Patients who did not attend follow-up appointments during this period could not have their FBG measured;thus, they were excluded from the glycemic control evaluation.
After the introduction of the telepharmacy application (August 2023), the prescriptions of eligible patients were prospectively reviewed. Using the application, we identified potential drug interactions and dispensed medications as usual. Before patients departed, we inquired whether they agreed to participate in telepharmacy counseling. Patients who provided consent were instructed to create an account and log in to access the telepharmacy counseling sessions, which were conducted via WhatsApp. These sessions were facilitated by trained pharmacists who underwent specific training, ensuring that they met the necessary qualifications for delivering counseling services as per the guidelines. These counseling sessions occurred in August and September 2023. Subsequently, we collected data on patients’ FBG levels in September and October 2023.
Finally, patients who received telepharmacy counseling were requested to complete a satisfaction questionnaire using Google Forms. Consenting patients were presented with five Yes/No questions concerning the application’s ease of access, convenience of use, and time-saving, knowledge enhancement, and perceived health benefits.
The initial primary outcome of this study focused on identifying potential drug-drug interactions (pDDIs). We aimed to compare the number of pDDIs detected manually using Medscape and those detected using the application. We anticipated that using the application would enhance the number of pDDIs detected due to its comprehensive database constructed from diverse sources. However, assessing the severity of these interactions was a challenge because it is intricately linked to the medications prescribed to individual patients.
The secondary outcome focused on glycemic control, which was assessed by measuring FBG levels twice. A controlled FBG level was defined within the range of 70–110 mg/dL (
We conducted descriptive analysis to illustrate the frequencies and percentages of categorical data, while we presented mean ± standard deviation or median (range) for continuous data. The characteristics of both prescriptions and patients between the groups were compared. We used an independent sample t-test (for parametric data) or Mann-Whitney U test (for non-parametric data) for continuous data, while we conducted Chi-square tests for categorical data.
To evaluate significant differences in the number of detected pDDIs, we compared the average of each group employing either an independent sample t-test (for parametric data) or the Mann-Whitney U test (for non-parametric data). In examining the relationship between the implementation of telepharmacy counseling and glycemic control, we used Chi-square and multivariable logistic regression analysis to consider variables such as sex and age concurrently. We employed listwise deletion to handle missing age and sex data, as the missing occurred completely at random (Kang, 2013). Moreover, the proportion of missing values accounted for less than 5% of the dataset, thus deemed inconsequential (
This study examined 250 and 255 prescriptions in the before and after-telepharmacy groups, respectively. Roughly 62% of patients in both groups were elderly (aged 60 years or more), and approximately 56% were women. More than 70% of prescriptions in both groups comprised 5–7 drugs. There were no significant differences in the characteristics of the prescriptions between the two groups. Table

Our study introduces a novel telepharmacy application tailored specifically for diabetes care, aiming to mitigate the challenges in the management of diabetes. Through its integration with advanced drug interaction checker functionalities, this application demonstrated remarkable efficacy in significantly enhancing the detection of potential drug interactions compared to manual assessments. This finding highlights the transformative potential of telepharmacy in augmenting pharmacists’ capabilities, particularly in identifying and managing complex drug interactions associated with polypharmacy in diabetes treatment.
Specifically, the rate of drug interaction detection was significantly higher in the after-telepharmacy implementation group than in the before-telepharmacy group (p < 0.05). Although the data were obtained from different populations, we inferred that there was minimal divergence in clinical conditions, as all participants were enrolled in the Prolanis program. Studies have confirmed that comorbidity among T2D patients in the Prolanis program typically includes hypertension (
This study also revealed a compelling correlation between telepharmacy counseling and improved glycemic control among diabetes patients. Those who engaged in telepharmacy counseling sessions exhibited a notably higher likelihood of achieving controlled FBG levels. This association emphasizes the pivotal role of patient education and remote counseling facilitated by the application in positively influencing health outcomes, potentially reducing long-term complications related to uncontrolled diabetes. The result aligns with those from prior research, such as a double-blind randomized controlled trial (RCT) in Turkey, a prospective-single cohort in Saudi Arabia, and a randomized trial in Denmark, which consistently demonstrated the positive impact of digital health technologies on glycemic control among individuals with diabetes (
In this study, patients expressed satisfaction with various aspects of the telepharmacy counseling application, especially time-saving, convenience of use, and knowledge enhancement. Similarly, a study in Spain found that diabetic patients reported high satisfaction with these aspects following telemedicine services (
This study’s strengths encompass a tailored intervention designed explicitly for Indonesian diabetes management, addressing a critical healthcare gap. By using a before-and-after approach, it offers practical insights into the real-world application of the telepharmacy model within the local healthcare system. Quantifiable outcomes, specifically in drug interaction detection and glycemic control, underscore its clinical relevance. The study’s promising outcomes signal the potential for a substantial impact on patient safety and treatment efficacy in Indonesia’s diabetes care. Moreover, the model’s adaptability hints at scalability, suggesting broader applicability beyond the study’s specific context and potential benefits for diverse healthcare settings.
However, this study has some limitations. Firstly, its design as a before-and-after study, lacking the rigorous control of an RCT, might introduce biases or confounding variables. The observational nature of the study restricts our ability to infer causal relationships. The relatively short duration of the study limits insights into sustained effects, warranting a longer follow-up period. In addition, limitations linked to sample size and participant characteristics may restrict the study’s representativeness and robustness, calling for a more extensive and diverse sample. Overlooking factors, such as the duration of diabetes, comorbidities, and dietary or lifestyle changes, as well as ignoring technological constraints in varied healthcare settings, could further impact the study’s comprehensiveness and generalizability.
Future research should encompass RCTs to strengthen causal inferences and minimize biases or confounders, while longitudinal studies are crucial for gaining insights into sustained intervention effects. To enhance study representativeness, robustness, and comprehensiveness, researchers should use diverse and larger populations, considering detailed patient profiles, including factors such as the duration of diabetes, comorbidities, and lifestyle changes. In addition, comprehensive assessments of technological and economic aspects, along with patient-centric approaches, will contribute to the improved application and understanding of telepharmacy in diabetes management.
The study underscores the positive impact of telepharmacy on drug interaction detection and glycemic control among Indonesian diabetes patients. The rate of drug interaction detection was significantly higher in the after-telepharmacy group than in the before-telepharmacy group, and patients receiving telepharmacy counseling were more likely to achieve controlled fasting blood glucose levels than those receiving conventional counseling. While we acknowledge the potential drawbacks of the study design, we contend that these research findings can serve as a foundation for understanding how telepharmacy can transform diabetes management and improve patient outcomes across various settings. Future research should aim for randomized controlled trials and longitudinal study designs with diverse and larger populations and should aim to assess technological feasibility and consider patient-centric approaches.
