Aims
The main aims of PHISICC are to create an innovative HIS for PHC and to assess its effects on data use and quality, quality of health care and health care worker perceptions, applied in rural settings in Côte d’Ivoire, Mozambique and Nigeria. The project was approved at the end of 2015, and research activities are planned to mid-2021.
Specifically, we aim at addressing the following research components, organised in six workstreams (WS):
-
Setting up a partnerships between research institutions and the governmental health sector in the three countries, to ensure country ownership, political relevance and scientific excellence (WS1)
-
Synthesising the research literature on the effects of HIS and carrying out a framework synthesis to understand how HIS are portrayed in research (WS2)
-
Characterising the use of HIS in the daily practice of frontline health workers in Côte d’Ivoire, Mozambique and Nigeria (WS3)
-
Designing an innovative paper-based HIS for the three countries (i.e. PHISICC paper-based tools) using a design process employing co-design, human centred design and service design (WS4)
-
Assessing the effects of the PHISICC tools on quality of data, data use and quality of care, through experimental studies in the three countries (WS5)
-
Disseminating the findings and advocating for policy uptake of the new evidence produced (WS6).
Overall research setup and rationale
The project proposal was developed by a core team composed by the main applicant institution, the design partner and countries’ researchers. As the proposal was being drafted, governmental health sector officials from LMIC in Africa and Asia were contacted to ascertain their participation interest for a research project focusing on paper-based HIS. Contacts were made leveraging past and current partnerships of the Swiss Tropical and Public Health Institute (Swiss TPH). We established five criteria to engage with a country: (i) the governmental health sector considered that the paper components of the HIS were going to stay for a long time; (ii) they acknowledge the existence of data quality issues; (iii) they demonstrated that data quality and use was a strategic priority; (iv) they were willing to accept transient changes to the HIS for research purposes; and (v) they considered the research relevant to eventually feed into future policy or strategic planning exercises.
The research project pivots around the creation of a new paper-based health information system intervention, using a design process employing co-design, HCD approach and service design (WS4), and testing it using experimental study designs (WS5). It was critical that the design process be informed by (i) existing evidence, (ii) real practices and (iii) workers’ HCD principles. For these reasons, the design work (WS4) was preceded by the systematic review of the literature (WS2) and the characterisation of the HIS in the countries (WS3). The findings from WS2 and WS3 where synthesised and entered into the co-creation design process (WS4). Equally important was the need to keep the whole research grounded on the real life of the countries’ settings and relevant to the strategic priorities of the Ministries of Health. Hence, we established a WS6 to ensure engagement, communication and advocacy with partners since the very conception of the project with concrete activities. The timeline of the project is shown in Figure 1.
Workstream 1: management and inception
The aims of the inception phase were to set up administrative and managerial procedures, formalise, partnerships and to draft generic protocols for each WS. In each country, we established two main engagements: we signed a Memorandum of Understanding with the relevant department of the governmental health sector; and we entered into contractual arrangements with partner national research institutions. Research partners were selected applying the following criteria: (i) they had, or were interested in having, a portfolio on health systems research; (ii) they had the capacity to manage a long-term project within a wider country partnership; (iii) the PHISICC project was consistent with their own research priorities.
In parallel, we identified international experts that could act as members of a Technical Advisory Group (TAG). The main function of the TAG is to support project partners in project design and implementation, and to monitor progress. We searched and selected experts on HIS, a public health care area (e.g. immunisation), research synthesis and policy, and HCD. TAG members operate on a voluntary basis. A chair was designated by consensus among the six TAG members and two representatives of the funding agency joined the TAG as observers. In the first year of the project, there was one ‘global’ workshop including the project team with country partners and the TAG.
Workstream 2: global evidence synthesis
We carried out a systematic literature review to synthesise the evidence on the effects of interventions targeting HIS [21,22], following standardized and widely accepted methods [23,24] and reporting practices. To address this ‘effectiveness’ question, we included experimental and quasi-experimental studies, in any language, carried out in LMIC. We did include in our review studies of any type of intervention targeting HIS, because we could not rule out that studies on, for instance, digital HIS interventions would not have findings or lessons relevant to paper tools. We did not restrict the concept of HIS to the routine HMIS, because we wanted to capture other sources of information that may come into play when making decisions, such as survey results, evaluations or even colloquial evidence.
While the systematic review was meant to provide evidence on the effects of interventions, the TAG raised a concern suggesting that in the systematic review on effectiveness we would miss evidence on systems, processes and human experience with the information system. The TAG encouraged the team to carry out another research synthesis to provide additional evidence on the characteristics of the HIS and its use for decision making, as reported in the research literature. Following this recommendation, we carried out a systematic ‘framework synthesis’ [25,26] based on observational, both quantitative and qualitative studies.
Workstream 3: local evidence on health information systems
We complemented global evidence from gathered in WS2 with local evidence through a characterisation of the HIS in-context of use. These characterisations were carried out in two-week field visits to remote, rural areas in each country, with a team of researchers, HCD experts and governmental health sector officials [27].
Visits were guided by a protocol and were structured around four main activities: an initial orientation workshop, in-depth interviews with stakeholders, visits to health facilities and restitution workshops. In the initial workshop, partners and stakeholders were updated on project progress and the field visit protocol was shared and adapted. Participatory techniques were used to facilitate engagement and gathering feedback. In-depth interviews addressed the roles of the main stakeholders in identifying and addressing HIS challenges.
Field visits were focused on (i) describing the general features of health facilities and the HIS; (ii) understanding the experience of frontline health workers using the HIS; and (iii) assessing the data quality of selected indicators in the HIS. A novel feature of the PHISICC approach was the application of HCD to understand the frontline health workers’ experience with the HIS. The HCD approach involved three to five hours of observations and interviews at each health facility. Activities included ‘shadowing health workers to observe their work with patients and tools, and interviewing them to understand their work, their challenges, and the degree to which current HIS tools supported or undermined their ability to do that work. Site visits and interviews were videotaped for detailed review and analysis. Current HIS tools and paper based registers were photographed to create a visual inventory of HIS in context. Informed consent was obtained from health workers and patients prior to recording and individualized patient information was scrubbed.
Workstream 4: Designing an innovative paper-based HIS using a design process
The design process consisted of co-design and service design methods with a HCD approach. Design has been used as a creative problem-solving approach to translate the findings from WS2 and 3 into usable, desirable, feasible and effective tools [28]. A HCD approach meant that the lived experiences of the health information system users, i.e. health care providers, would be a key aspect of the design decisions (desirability and usability) that needed to be made next to decisions around clinical standards and guidelines (e.g. Integrated Management of Childhood Illness [29]).
Co-design methods refer to designers' creative activity and people not trained in design, working together in the design development process. Service design methods refer to activities thinking through the HIS’ conceptualisation as a service with providers and end-users, using tools such as journey mapping, prototyping, and information design to design consistent and seamless service experiences [30]. Co-creation groups were formed to enable the co-design activities, with twelve members from the three partner countries. The co-creation team's role was to co-produce and co-decide on the tools versions, providing their in-country expertise, technical expertise and contextual understanding. The group also contributed to user-testing activities with front-line workers to iterate the tools based on user feedback [31].
The new PHISICC paper-tools include all main health care areas at PHC: antenatal care, delivery, postnatal care, vaccination, sick child, outpatient consultations, HIV and tuberculosis; and the recording, tallying and reporting sub-systems (i.e. recording with register books for individual patient care and tallying and reporting to provide aggregated figures to the higher tiers of the health system). Tools were harmonised across countries, produced in their official languages (English in Nigeria, French in Côte d’Ivoire and Portuguese in Mozambique) and adapted to country specific requirements (e.g. different vaccination schedules). The final versions of the tools were locally produced to supply HF in the intervention arms during the testing period (see WS5).
Workstream 5: evaluation of the intervention using randomised controlled trials
The PHISICC paper-based tools are being tested in real life situations, using a cluster randomised controlled trial design in the three countries [32,33]. Study areas have been selected based on the availability of remote, rural health facilities, serving vulnerable populations, and being reasonably accessible to carry out research activities. The unit of intervention are the health facilities, which were randomly allocated to the intervention or control arms. In each country, 35 HF were allocated to each arm. In the intervention arm, current HIS paper-based tools were substituted by the new PHISICC tools in order to avoid duplicate recording and reporting. Field work is quality monitored to identify potential problems during the trial implementation.
The outcomes of interest include: (i) health related outcomes (e.g. vaccination coverage rates); (ii) data quality (e.g. consistency between recorded and reported data) and data use outcomes (e.g. documented decisions made based on data); (iii) user related outcomes, both for service providers and patients (e.g. acceptability and usability of new tools); and (iv) resource consumption outcomes (e.g. time spent in reporting data, costs). The effect of the intervention will be estimated by comparing intervention and control arms at end-line (for outcomes where only the end-line is available) or differences between baseline and end-line (for outcomes where both baseline and end-line are measured) using regression models taking the structure of the data into account. We have also started to gather qualitative data in order to better understand how the intervention may be working and what are feasible explanations for the observed effects.
Workstream 6: stakeholders engagement, communication and policy advocacy
WS6 started at the very inception of the project and remains active along the whole project activities (Figure 1). Stakeholders’ engagement and countries’ ownership are core components of this research to keep it rooted in the reality of the three countries and relevant to the policy contexts. To this end, we have actively adhered to the 11 principles of transboundary research [34], as shown in Table 1.
Communication tools are being leveraged to increase awareness of PHISICC and to allow stakeholders to follow on events. These include activity report [35], a website (phisicc.org), a twitter account (@phisicc_), a newsletter (‘The Tally’) and numerous internal memos and updates.
WS6 includes plans to uptake the evidence and lessons learned from PHISICC, which go far beyond the findings of the WS5; including approaches, methods and lessons learned from interactions with frontline health workers.
Status of the study
In all three countries, WS3 and WS4 have come to an end. Currently the trial (WS5) is on-going in each of the three countries. Data collection has begun in the sense that the baseline data collection was completed in 2020. The end-line data collection has not yet begun.
