Managing infectious diseases requires a rapid and effective response to support decision-making. The decisions are complex and require an understanding of the disease, disease intervention and control measures, and the disease-relevant characteristics of the local community (Standley et al., 2018). Disease surveillance improves the flow of information needed to monitor disease spread, and to evaluate the effectiveness of control and preventive measures. The Integrated Disease Surveillance and Response (IDSR) tool and the Surveillance Outbreak Response Management and Analysis System (SORMAS) capture all the surveillance data on COVID-19 and other vaccine preventable diseases (VPD) in Nigeria. Having a robust database is not enough to support decision making process, but data must be analyzed and transformed into evidence-informed decision-making (EIDM).
The insufficient digital infrastructure, including internet connectivity and technology resources, in the state of Anambra, Nigeria, causes difficulties in gathering, storing, and sharing health data effectively. The state of Anambra stores health information in a number of disparate systems, making integration and access difficult. Health records that are fragmented or unavailable make it difficult to provide effective healthcare. There are barriers with access to comprehensive health data for study is a difficulty for researchers, legislators, and public health professionals. The ability to establish tailored treatments and policies is also constrained by restricted data availability, which may impede decision-making based on the available evidence. Together, governments, healthcare professionals, and technology stakeholders must work to close these gaps by investing in digital infrastructure, putting in place strict data security and privacy controls, encouraging interoperability, and standardizing data collection techniques (Ezenwaka et al, 2020).
EIDM has a large and growing evidence base, spanning a wide range of disciplines (Punton et al., 2016). EIDM is used when people who need to make choices use the best available evidence to motivate their decisions. Evidence can refer to scientific research but equally to citizens' voices, SORMAS data, or expert opinion, among other sources. EIDM aims to use the best available evidence for the decision at hand. It aims for evidence that is fit-for-purpose, suitable for the context, and scalable for the decision to be taken (Africa Evidence Network, 2021).
Among the many barriers to the use of evidence in decision-making, the low capacity of decision makers has attracted much focus in the last decade (Uneke et al., 2010). Therefore, there is an opportunity to promote evidence use by presenting and discussing the experiences on COVID-19 response, and thereby strengthening individual and institutional capacity for evidence use amongst the surveillance actors. Developing the capacity of decision-makers to use research evidence through building knowledge, skills, commitment, relationships, and systems will allow for access, appraisal, and application of good quality evidence more effectively when forming policy. The use of research evidence will improve the quality of policies, ultimately benefitting more people experiencing poverty. Capacity development is a complex and multi-dimensional process that demands and involves more than a focus on individual skills, requiring intervention at individual, interpersonal, organizational, and institutional levels
Studies examining individual-level interventions, particularly training, suggest combining classroom learning with on-site projects to actively engage participants (Duong et al, 2022). Organizations may link to training success, especially as supporting organizations appeared to be an important contextual factor influencing training impact. One helpful way of understanding the mechanism through which training can improve capacity is the self-efficacy theory – training increases participants' confidence in their capability to perform a specific task or handle a particular situation. (Punton et al., 2016). Reports relating to interpersonal-level interventions discussed the role of networks, knowledge brokers, and champions in promoting EIDM (Punton et al., 2016). Individuals can lead to change through the mechanisms of 'cheerleading,' acting as 'transformational leaders' or 'network facilitators,' or promoting 'social learning' through role-modeling EIDM behaviors. Effective champions and knowledge brokers possess specific interpersonal skills, vision and commitment, and an appropriate level of seniority in an organization. The evidence on networks suggests that they may lead to change through the mechanism of 'social processing' – in which beliefs within a group shift towards a consensus – which may lead away from EIDM towards it. (Punton et al., 2016).
Training and mentorship programs in EIDM effectively improved the competencies of civil servants (Poot et al., 2018). However, such programs need to train a critical mass to enhance EIDM practice effectively. (Poot et al., 2018). EIDM tools may also lead to change by increasing the value placed on evidence by convincing them of the benefit of data for decision-making. A virtuous circle may emerge, in which increased use of evidence leads to greater demand for it, and so on (Punton et al., 2016). Although solid individual and institutional capacities are critical in enabling evidence-informed decision-making (EIDM), these remain weak in many developing countries for many reasons. Lack of EIDM training programs for civil servants and low priority and investments in strengthening institutional structures and mechanisms for enabling EIDM are some of those reasons (Poot et al., 2018).
The study measured the difference between pre-workshop and post-workshop knowledge, this implies that the study aimed to evaluate the outcomes of the workshop, and the workshop aimed to enhance the capabilities of surveillance actors in using evidence informed decision-making on disease outbreak management and response of COVID-19 in Nigeria. The intervention aimed to improve the knowledge and capacity of surveillance actors to access and utilize relevant research evidence and data analysis options on for COVID-19 response, and to interpret data to inform decision-making on COVID-19 response.
The study was conducted in Anambra State, located in the southeastern area of Nigeria, which has a population of more than 4 million people. The state capital is Awka, and it has two tertiary hospitals, various secondary facilities, and several primary healthcare centers. At the time of the study, Anambra State had approved and executed an Incident Action Plan to respond to COVID-19, with surveillance being one of the crucial components to guarantee an effective response. Additionally, as of July 2023, disease surveillance efforts are ongoing in health centers and communities.
The study design used in this research was a modified "before and after" intervention study design. This design was used to evaluate the effectiveness of an intervention by measuring the outcomes of the participants before and after the intervention. In this study, the intervention was given to a specific group of individuals, and the outcomes were measured using a 5-point Likert scale.
A Likert scale is a commonly used survey tool that measures people's attitudes or perceptions on a particular subject (Elliott, 2021). In this case, the Likert scale was used to measure the adequacy of the outcomes on the target participants. The scale ranged from 1 to 5, with 1 indicating grossly inadequate outcomes and 5 indicating very adequate outcomes. We analyzed the difference between the before and after measurements to evaluate the effectiveness of the intervention and to determine whether it had a positive or negative impact on the outcomes.
The sample size in this study comprised 42 surveillance actors, who were selected using purposive sampling. Purposive sampling is a non-probability sampling technique where participants are selected based on specific criteria or characteristics that are relevant to the research question. In this case, the participants were selected from surveillance officers - local government area (LGA) Disease Surveillance and Notification officers (DSNOs) and contact tracers - who were deemed appropriate for the study. Finally, it's important to note that all 42 eligible DSNOs were physically present, which indicates a high level of participation and engagement in the study, and enhances the validity of the study findings.
The Anambra State Health Research Ethics Committee (ANSHREC-01-01-2009-08-01-2022) gave approval for the study, and all procedures were conducted in accordance with appropriate regulations and guidelines. The study protocol, including the informed consent statement, was approved prior to the research. Before conducting the study, research respondents provided informed consent. Written informed consent was obtained and confidentiality ensured.
The data collection process described in the scenario involves two main components: a pre-workshop survey and a one-day training workshop. The pre-workshop survey was in questionnaire format, and contained a mix of open-ended and closed-ended questions. The respondents were asked to complete the questionnaire before attending the training workshop. The questionnaire was interviewer-administered, meaning that a trained interviewer reads the questions to the respondent and records their answers.
The questionnaire was designed to collect information on several topics, including socio-demographic information such as age and level of education, as well as knowledge on surveillance, the use of data analysis tools, and data interpretation for informed decision making. The purpose of the pre-workshop survey was to establish a baseline of knowledge and skills among the participants before they attended the training workshop.
The one-day training workshop was organized for the 42 invited participants, and covered several topics related to surveillance, including Active Case Search, Event-Based Surveillance, Using ICT for measuring central tendency, and Developing capacity on internet use for evidence synthesis. The workshop was designed to be interactive and hands-on, with participants engaging in group activities and discussions to reinforce their learning. The goal of the workshop was to improve the participants' knowledge and skills in the areas covered by the training, and to equip them with the tools and techniques needed to collect and interpret data for informed decision making.
The baseline information was compared to the post-workshop questionnaire to evaluate the effectiveness of the training workshop by comparing the participants' knowledge and skills before and after the training.
The independent variables of interest in this study were gender and age category, which were measured using a structured questionnaire. Gender was categorized into two groups: male and female, while age category was determined by the respondent's age at their last birthday. The mean and standard deviation were calculated for age. The remaining independent variables were measured using nominal or ordinal scales and were subsequently recoded into two categories. For categorical variables, frequencies and proportions were calculated.
The data obtained through the 5-point Likert scales were examined using the Statistical Package for Social Sciences (SPSS) version 23 software for Microsoft Windows (IBM SPSS Statistics Version 23). Frequencies and proportions were computed for categorical variables, while means and standard deviations were calculated for other variables. The independent variables in the study were socio-demographic characteristics, while the dependent variables were knowledge of surveillance activities and data utilization for decision-making. The study also assessed the level of collaboration between surveillance actors and policymakers in utilizing informed evidence for decision-making. Additionally, the evaluation involved examining the process of assessing, adapting, and implementing evidence-informed practices relevant to decision-making. Complexity and factors influencing the use of informed evidence in decision making were determined.
All the forty-two (42) surveillance actors invited for this intervention workshop research attended the workshop and participated throughout the process of both the pre and post-intervention workshops of this research study. A total of 42 complete questionnaires were collected in the pre and post-workshop of this research and were included in the analysis for this study. Table 1 shows the socio-demographic characteristics of the respondents. There were 71% females and 29% males: 61.9% of the respondents were within the age range >45 years while only 2.3% were within the age range of greater than 25 years.
The percentage of years of experience in current designation showed that 40.4% of the surveillance actors have 6–10 years of experience in their designation. 12.0% of the respondents had diplomas, 26.0% had bachelor’s degrees, 36.0% had master’s degrees and 36.0% had a doctorate degree as their highest educational qualification.
