1. Background

Effective management of the medicine supply chain is crucial for ensuring the availability of essential medicines and supplies in public health facilities [1]. The logistics management information system ensures commodity availability, facilitates service-seeking in the community, and enhances the quality of care [2]. Competence in the Electronic Logistic Management Information System (e-LMIS) is essential for supporting the supply chain by enabling effective system utilization, encompassing skills such as data management, procurement, and distribution of medicines [3]. In the supply chain cycle of health commodities, procurement, distribution, and inventory management are crucial stages that can significantly impact the products' accessibility and affordability for end-users [4].
The main drivers associated with an effective supply chain are demand management, institutional framework, good governance, and management involvement in decision-making regarding e-LMIS implementation [5]. The functionality of health facility management teams is crucial for overseeing daily operations and medicine supplies, especially in the context of quality healthcare service delivery [6]. However, the majority of healthcare workers in public health facilities in developing countries often lack competence in information systems due to barriers such as lack of information technology training, workload, and the availability of the Internet, computers, and electricity [7]. Despite the introduction of the e-LMIS in Tanzania, the medical commodities supply chain is still a challenge [5,8].
User competence is paramount for the successful implementation of eLMIS [9]. Given the fact that e-LMIS is implemented in the context of low-resource settings, there is a need to evaluate its impact on medicine supply chain performance. However, there is a scarcity of research that has been conducted to assess the competence of healthcare workers at public health facilities. Thus, this study aimed to determine the utilization of e-LMIS in public health facilities and its implications for the medicine supply chain in Singida District Council, Tanzania. By addressing this research gap, evidence-based solutions can be developed to improve e-LMIS management and enhance the availability of essential medicines in public health facilities.

2. Methodology

2.1. Study Area

The study was conducted in Singida District Council, part of Tanzania's Singida Region. Singida District Council is responsible for public services in the district, located between latitudes 30 and 70 south of the equator and longitudinally between 330 and 350 east of Greenwich. It shares borders with Mkalama District to the north, Manyara and Dodoma regions to the east, Ikungi District to the south, and Singida Municipality to the west. The district covers an area of 3,787 square kilometers and serves a population of about 304,616 as of the 2022 population census [10]. Within the district are 39 health facilities, including hospitals, health centers, and dispensaries.

2.2. Study Design, Study Population

This study employed a mixed-methods approach, combining both quantitative and qualitative data collection methods. The study was conducted from July to September 2023. Quantitatively, it utilized a descriptive cross-sectional study design through surveys. Qualitatively, key informant interviews were conducted.

The study focused on healthcare providers responsible for using and managing the e-LMIS in public health facilities within Singida District. This included nurses, medical officers, pharmaceutical personnel, and staff involved in the medicine supply chain management process.
Participants included healthcare providers in public health facilities in Singida District who had received training on e-LMIS. They were selected based on their willingness to participate and their availability during data collection. Six key informants were also selected purposefully for in-depth interviews.

2.3. Data Collection Method

2.3.1. Quantitative Data Collection

Quantitative data for this study were collected through a structured questionnaire and a competence assessment tool. A team of three trained research assistants administered the questionnaires, ensuring the effective collection of data. The structured questionnaire was administered in interviews with participants.

2.3.2. Qualitative Data Collection

Qualitative data for this study were collected through in-depth interviews with key informants. During these interviews, digital recorders were used to ensure that no valuable information was missed. Prior permission to use a voice recorder was obtained from participants.
Six key informants were purposefully selected for in-depth interviews. Two in-charges were randomly selected from two dispensaries, two key informants from two health centers, and the remaining two participants from the district hospital. These key informants provided valuable insights into the factors influencing the competence of healthcare workers in utilizing e-LMIS and its impact on the management of the medicine supply chain in health facilities in Singida District.

2.4. Data Management and Analysis

2.4.1. Quantitative Data Management and Analysis

Data were coded, entered, cleaned, and analyzed using the Statistical Package for Social Studies (SPSS) version 26. Demographic characteristics, e-LMIS utilization, and competence were analyzed using descriptive statistics. Means, standard deviations, frequencies, and percentages, were used as appropriate.

2.4.2. Qualitative Data Management and Analysis

Qualitative data obtained from in-depth interviews underwent content analysis, following a structured process. Initially, audio files were transcribed verbatim and translated into English. The data were organized by categorizing and familiarizing information from the interview transcripts, grouping responses under each relevant topic and unique question. Repeating concepts, patterns, and ideas were then identified, with repeating words or ideas being observed and classified. Inductive coding was employed, and codes were assigned to categories. This coding process was carried out separately by two individuals to minimize intercoder variability, and codes with a high degree of agreement were retained. Subsequently, data concepts were synthesized into overarching themes to provide a deeper understanding of the data. These resulting themes were then described, and the relationships between them were interpreted. To facilitate this qualitative data analysis process, NVivo 11 software was utilized.

2.5. Ethical Consideration

The study obtained ethical approval from the Joint Catholic University of Health and Allied Sciences and Bugando Medical Centre Research and Ethics Review Committee, with permit number CREC/691/2023. Permissions were also obtained from relevant authorities and informed consent was sought from study participants. Confidentiality and privacy were strictly maintained during the data collection process.

The reliance on consultation with the regional pharmacist exemplified how such support mechanisms aided participants in resolving challenges and optimizing their utilization of the e-LMIS system.
Participant 4:I consult with the regional pharmacist if I have any issues or concerns regarding the system. Consulting with experienced pharmacists when facing issues or concerns is essential.

3.2.3. Theme 3: e-LMIS Implications on Medicine Supply Chain

Competence in utilizing the e-LMIS system yields a range of positive outcomes that significantly influence the efficiency of the drug supply chain. Respondents noted that orders were received promptly, and the drugs requested aligned with what was delivered. This marked an improvement from the past when discrepancies were common.
Participant 6:"We now receive drugs on time, and the drugs we order are the ones we receive." These positive outcomes underscore the significance of competence in e-LMIS utilization. Participants described how their competence played a vital role in preventing stock outs and enhancing decision-making processes. The real-time insight not only prevents stock outs but also streamlines resource allocation by ensuring that orders align with actual requirements, rather than relying on manual records and guesswork.
Participant 1:" e-LMIS has positively affected decision-making because I can access real-time information. This allows me to make informed decisions based on the current situation, which is more efficient than relying on manual records. We have not experienced stock outs for a long time because we receive accurate information."
Furthermore, competence directly influences the decision-making processes of participants, enabling them to make strategic choices regarding which items to order.
Participant 5:" e-LMIS influences my decisions in that I know what to do next time, like whether to order a certain item or not."
Participant 1:" e-LMIS has positively affected decision-making because I can access real-time information

3.2.4. Theme 4: Strategies for Improvement

Participants stressed the significance of regular training programs and capacity-building initiatives. They advocated for the provision of consistent and structured training to strengthen skills in navigating the e-LMIS system effectively. Such training programs, tailored to the needs of healthcare workers, can play a pivotal role in keeping participants updated on system advancements, best practices, and emerging trends.
Participant 6:"I think regular training should be provided to strengthen skills in how to use the system. I believe they should refresh us if there are any updates."
Participant 1:"Dedicated training programs would be extremely beneficial."
Additionally, participants offered insightful recommendations for system enhancements. One prominent suggestion was the automation of certain items' inclusion in the e-LMIS system. The automation would not only streamline processes but also mitigate the risk of errors, as items vital to healthcare operations would already be integrated into the system. Such enhancements can simplify the workflow for healthcare workers, reduce the burden of data entry, and further enhance the overall efficiency of the e-LMIS system.
Participant 5: "It would be good if, for example, certain items that should be in the hospitals were automatically in the system."
Moreover, informants proposed simplifying the e-LMIS system itself, making it more user-friendly. Given its extensive functionalities, simplification was seen as a means to enhance user experiences.
Participant 3: "Another way is to improve the system itself. It's quite extensive, so if there's a way to simplify it, that would be helpful." This suggestion aligns to make the system more accessible and efficient.

4. Discussion

The effectiveness of the various procedures and aspects of the supply chain system, such as storage, transportation, planning, and forecasting, depends greatly on the logistics management information system [11]. This study assessed the competence of e-LMIS among public healthcare workers and its implications for medicine supply chain performance. The majority of study participants in the present study reported being at least somehow competent in utilization and confident in their supply chain duties using e-LMIS. This is consistent with the previous study conducted in Ethiopia, where about 95% of respondents reported being satisfied with their ability to use e-LIMS for inventory management and managing day-to-day activities [12].
In-depth views highlighted several factors that influence competence in the utilization of e-LIMS. Participants cited several aspects contributing to their competence in using e-LMIS. These factors were regular usage of the system, training, and support, both from experienced colleagues and the Ministry of Health, and the presence of educational resources. Other factors were management support and access to experienced pharmacists for consultation when facing system-related issues. Previous studies reported training, educational status, availability of automated record systems, supportive supervision, and years of work experience in supply chain management as factors associated with competence in the utilization of e-LIMS [2,13]. The competence in electronic recording and reporting among healthcare workers impacts medicine supply chain performance by reducing errors and task burden, saving time, influencing the availability of drugs, and improving reporting rates [14,15]. A previous study revealed that e-LMIS contributes to data accessibility at 94.9%, reduction of quantification challenges at 57.6%, improved the quality of data by 77.9%, and inventory management of health products to optimum levels, with a decrease in expiry-related losses [16].
A prior study reported that eLMIS provided real-time health commodity data from user units. The data were essential for medicine supply chain performance as they are used for the planning and management of health commodities, informing the quantification, forecasting, and pipeline monitoring of commodities at all levels of care and decision-making [17]. In this study, competence in utilizing e-LMIS emerges as a critical factor in preventing stockouts and influencing decision-making processes. Real-time insights provided by the system enable participants to anticipate demand accurately, thereby avoiding situations where essential drugs are unavailable. This not only ensures continuous availability but also optimizes resource allocation, minimizing waste and maximizing efficiency. Two key issues limiting competence in e-LIMS utilization reported in this study were shortages of staff and a lack of customized training for health workers. Prior research has identified several limitations, including complexities within the system, an inadequate workforce, authorities' and users' accountability, and an inadequate structure to facilitate the organization and management of the health supply chain system [16,18]. In-depth interviews with study participants revealed that regular training programs, capacity-building activities, system automation, and simplification are effective ways to enhance the impact of e-LMIS on the medicine supply chain.
Certain limitations should be taken into account while considering the results reported in this research. The cross-sectional design used provides a snapshot of e-LMIS utilization but doesn't capture long-term trends or establish causality. Self-reporting bias could potentially affect the accuracy of participants' responses, particularly in assessing their competence levels. The study's area focus on Singida District may restrict the generalizability of findings to other healthcare contexts within Tanzania. Nonetheless, this study serves as a valuable foundational resource for future research and policy development in healthcare supply chain management in the region, offering insights into how to enhance e-LMIS utilization effectively.

5. Conclusions

This study found that an adequate proportion of healthcare providers demonstrated competence in utilizing the e-LMIS. Moreover, the study highlighted the positive impact of e-LMIS on various aspects of the medicine supply chain, including the timely submission of orders and enhanced inventory management. However, challenges such as staff shortages and inadequate training were identified as barriers to the system's optimal functioning. Sustained management support and regular utilization of the e-LMIS system are crucial for building and maintaining competence among healthcare providers, thereby optimizing the medicine supply chain and ultimately improving healthcare delivery.
