Responding to maternal, neonatal and child health equipment needs in Kenya: a model for an innovation ecosystem leveraging on collaborations and partnerships

Avoid equipment graveyards: rigorous process to improve identification and procurement of effective, affordable, and usable newborn devices in low-resource hospital settings

BACKGROUND

Millions of newborns die annually from preventable causes, with the highest rates occurring in Africa. Reducing neonatal mortality requires investment to scale hospital care, which includes providing hospitals with appropriate technology to care for small and sick newborns. Expensive medical devices designed for high-resource settings often fail to withstand conditions in low-resource hospitals, including humidity, dust, frequent user turnover, complex maintenance, lack of stable power, or difficulty sourcing expensive consumables. Rigorous evaluation protocols are needed to identify effective, affordable, rugged, and easy-to-use medical devices appropriate for quality hospital-based newborn care in low-resource hospitals.

METHODS

We developed an evidence-based technology review process to identify medical devices suitable for small and sick newborn care in low-resource hospitals. The eight-step process consists of: identifying devices needed for effective newborn care; defining Target Product Profiles (TPPs); identifying commercially-available products that may meet TPPs; conducting desk research to evaluate technologies against TPPs; performing technical performance verification testing under laboratory conditions; verifying technical performance after exposure to heat, humidity, dust, and power loss; performing usability evaluations with nurses, and qualifying devices that pass all steps. Devices were purchased, installed, and monitored in newborn wards across Kenya, Malawi, Nigeria, and Tanzania.

RESULTS

Of 271 devices considered, only 45 (16.6%) met corresponding TPPs based on desk research. Thirty-nine were purchased and evaluated in the laboratory; five (12.8%) failed to meet TPPs. Thirty-four products passing laboratory evaluation underwent short-term environmental testing; only one (2.9%) device failed. Thirty-seven products underwent usability testing with 127 clinicians; surprisingly, 14 (37.8%) failed to meet TPPs. Twenty-three products passed all evaluations, and 2457 devices were installed across 65 newborn wards in Kenya, Malawi, Nigeria, and Tanzania. Continuous device monitoring reported minimal device failures, with failed devices typically returned to service within two days, resulting in an average uptime (service days divided by days installed) of 99%.

CONCLUSION

An evidence-based device selection process can improve procurement of effective, affordable, rugged, usable newborn care devices for low-resource hospitals, and feedback to manufacturers can improve device quality. Similar processes could be adapted beyond newborn care to identify medical devices suitable for implementation in any low-resource setting.

Medical device regulation and oversight in African countries: a scoping review of literature and development of a conceptual framework

Regulatory and other governance arrangements influence the introduction of medical devices into health systems and are essential for ensuring their effective and safe use. Challenges with medical device safety, quality and use are documented globally, with evidence suggesting these are linked to poor governance. Yet, medical device regulation and oversight remain inadequately defined and described, particularly in low-income and middle-income settings. Through this review, we sought to examine the literature available on regulatory and oversight processes for medical devices in African countries.Following a systematic approach, we searched academic databases including PubMed, Embase (Ovid) and MEDLINE (Ovid), supplemented by search for grey literature and relevant organisational websites, for documents describing medical device regulation and oversight in African countries. We summarised the data to present key actors, areas for regulation and oversight and challenges.A total of 39 documents reporting regulation and oversight of medical devices were included for analysis. Regulatory and oversight guidelines and processes were reported as inadequate, including limited pre-market testing, reliance on international certifications and limited processes for post-market monitoring and reporting of adverse events. Challenges for regulation and oversight reported included inadequate funding, personnel and technical expertise to perform regulatory functions. The literature highlighted gaps in guidelines for donated medical devices and in information on governance processes at the national level.The current literature provides a general overview of medical device regulatory guidelines and limited evidence on the implementation of regulatory/oversight processes at national and especially subnational levels. We recommend further research to elucidate existing governance arrangements for medical devices within African countries and propose a conceptual framework to inform future studies. The framework provides entry points for careful examination of governance and oversight in policy and practice, the exploration of governance realities across the health system and the influence of wider system dynamics.

Ending Neonatal Deaths From Hypothermia in Sub-Saharan Africa: Call for Essential Technologies Tailored to the Context

Neonatal death represents a major burden in Sub-Saharan Africa (SSA), where the main conditions triggering mortality, such as prematurity, labor complications, infections, and respiratory distress syndrome, are frequently worsened by hypothermia, which dramatically scales up the risk of death. In SSA, the lack of awareness on the procedures to prevent hypothermia and the shortage of essential infant devices to treat it are hampering the reduction of neonatal deaths associated to hypothermia. Here, we offer a snapshot on the current available medical solutions to prevent and treat hypothermia in SSA, with a focus on Kenya. We aim to provide a picture that underlines the essential need for infant incubators in SSA. Specifically, given the inappropriateness of the incubators currently on the market, we point out the need for reinterpretation of research in the field, calling for technology-based solutions tailored to the SSA context, the need, and the end-user.

The RAIS Device for Global Surgery: Using a Participatory Design Approach to Navigate the Translational Pathway to Clinical Use

Background: Over 5 billion people worldwide have no access to surgery worldwide, typically in low-resource settings, despite it being a primary life-saving treatment. Gas Insufflation-Less Laparoscopic Surgery (GILLS) can address this inequity, by improving current GILLS instrumentation to modern surgical standards. Objective: to develop and translate a new Retractor for Abdominal Insufflation-less Surgery (RAIS) into clinical use and thus provide a context-appropriate system to advance GILLS surgery. Methods: A collaborative multidisciplinary team from the UK and India was formed, embedding local clinical stakeholders and an industry partner in defining user and contextual needs. System development was based on a phased roadmap for ‘surgical device design in low resource settings’ and embedded participatory and frugal design principles in an iterative process supported by traditional medical device design methodologies. Each phase of development was evaluated by the stakeholder team through interactive workshops using cadaveric surgical simulations. A Commercialisation phase undertook Design to Manufacture and regulatory approval activities. Clinical validation was then conducted with rural surgeons performing GILLS procedures using the RAIS system. Semi-structured questionnaires and interviews were used to evaluate device performance. Results: A set of user needs and contextual requirements were defined and formalised. System development occurred across five iterations. Stakeholder participation was instrumental in converging on a design which met user requirements. A commercial RAIS system was then produced by an industry partner under Indian regulatory approval. This was successfully used in clinical validation to conduct 12 surgical procedures at two locations in rural India. Surgical feedback showed that the RAIS system provided a valuable and usable surgical instrument which was appropriate for use in low-resource contexts. Conclusions: Using a context-specific development approach with close engagement of stakeholders was crucial to develop the RAIS system for low-resource regions. The outcome is translation from global health need into a fully realized commercial instrument which can be used by surgeons in low-resource regions across India.

Devolved health system capacity in the provision of care for sick newborns and young infants in four counties serving vulnerable populations in Kenya

Possible severe bacterial infections (PSBI) is one of the three leading causes of newborn and young infant mortality globally that can be prevented by timely diagnosis and treatment using suitable antibiotics. High impact interventions such as use of out-patient injectable gentamicin and dispersible Amoxicillin with community-based follow up have been shown to reduce mortality in clinical trials. The objective of this study was to assess the health systems' preparedness and organizational gaps that may impact execution in providing care for newborns and sick young infants. This formative research study was embedded within a three-year implementation research project in 4 Counties in Kenya. The indicators were based on facility audits for existing capacity to care for newborns and young infants as well as County organizational capacity assessment. The organizational capacity assessment domains were derived from the World Health Organization's Health Systems Building blocks for health service delivery. The scores were computed by adding average scores in each domain and calculated against the total possible scores to generate a percentage outcome. Statistical analyses were descriptive with adjustment for clustering of data. Overall, the Counties have inadequate organizational capacity for management of sick young infants with Organizational Capacity Index scores of between 61-64%. Among the domains, the highest score was in Health Management Information System and service delivery. The lowest scores were in monitoring and evaluation (M&E). Counties scored relatively low scores in human resources for health and health products and commodities with one scoring poorly for both areas while the rest scored average performance. The four counties revealed varying levels of organizational capacity deficit to effectively manage sick young infants. The key underlying issues for the below par performance include poor coordination, low funding, inadequate supportive supervision, and M&E to enable data utilisation for quality improvement. It was evident that newborn and young infant health services suffer from inadequate infrastructure, equipment, staffing, and coordination. As Kenya, continuously rolls out the guidelines on management of sick young infants, there is need to focus attention to these challenges to enhance sustainable adoption and reduction of young infant morbidity and mortality.

Critical Interpretive Synthesis of Qualitative Data on the Health Care Ecosystem for Vulnerable Newborns in Low- to Middle-Income Countries

OBJECTIVE

To critically assess and synthesize qualitative findings regarding the health care ecosystem for vulnerable (low-birth-weight or sick) neonates in low- to middle-income countries (LMICs).

DATA SOURCES

Between May 4 and June 2, 2020, we searched four databases (Medline [PubMed], SCOPUS, PsycINFO, and Web of Science) for articles published from 2010 to 2020. Inclusion criteria were peer-reviewed reports of original studies focused on the health care ecosystem for vulnerable neonates in LMICs. We also searched the websites of several international development agencies and included findings from primary data collected between May and July 2019 at a tertiary hospital in Kenya. We excluded studies and reports if the focus was on healthy neonates or high-income countries and if they contained only quantitative data, were written in a language other than English, or were published before 2010.

STUDY SELECTION

One of the primary authors conducted an initial review of titles and abstracts (n = 102) and excluded studies that were not consistent with the purpose of the review (n = 60). The two primary authors used a qualitative appraisal checklist to assess the validity of the remaining studies (n = 42) and reached agreement on the final 13 articles.

DATA EXTRACTION

The two primary authors independently conducted open and axial coding of the data. We incorporated data from studies with different units of analysis, types of methodology, research topics, participant types, and analytical frameworks in an emergent conceptual development process according to the critical interpretive synthesis methodology.

DATA SYNTHESIS

We synthesized our findings into one overarching theme, Pervasive Turbulence Is a Defining Characteristic of the Health Care Ecosystem in LMICs, and two subthemes: Pervasive Turbulence May Cause Tension Between the Setting and the Caregiver and Pervasive Turbulence May Result in a Loss of Synergy in the Caregiver-Parent Relationship.

CONCLUSION

Because pervasive turbulence characterizes the health care ecosystems in LMICs, interventions are needed to support the caregiver-parent interaction to mitigate the effects of tension in the setting.
