Successes and Barriers Experienced in the Implementation of KMC

KMC is an important “example of both South-South and South-North knowledge transfer” in evidence-based medical care, and its benefits have been observed across settings (Bergh, 2007). Since its inception in 1978, extensive evaluative research was conducted by the Fundación Canguro, and a formal training program for other large public hospitals in Colombia and developed countries was initiated in 1994 (Rosero, n.d.). The model of KMC dissemination is “see one, do one, teach one” (the SODOTO model): health care leaders are invited to the Fundación Canguro center for training (“see one”), to run a KMC program in their home institution (“do one”) and then train others in their region for further KMC implementation (“teach one”) (N. Charpak, personal communication, 7 December 2018). Knowledge transfer has been slow but successful in Colombia, as practices are culturally acceptable and effective. Nearly all the teams trained in Bogotá successfully set up programs, despite limited equipment. At present there are about 35 regional KMC programs in public and private institutions offering the same “KMC package” that is compatible with health ministry rules (N. Charpak, personal communication, 7 December 2018).

Characteristic of any new programming or change to standard practice, challenges were faced in KMC’s introduction and implementation.  As reported by Fundación Canguro, KMC had to overcome initial resistance from healthcare workers and difficulties regarding appropriate discharge and follow-up procedures (Rosero, n.d.). Specifically, nurses had initial distrust regarding mother’s competence to care for the child at home and neonatologists resisted changes to routine medical practices. A summary of barriers faced during adoption of KMC in low and middle income countries can be seen in Figure 1 of the Appendix.  To address concerns and challenge perceptions that KMC may increase hospital workload, staff were appropriately trained and educated, and an intrahospital kangaroo adaptation unit was created (Rosero, n.d.). In the adaptation unit, staff trained mothers on KMC and evaluated discharge eligibility. Discharge criteria were essential for combatting administrative pressures to release infants early from overcrowded facilities.

Additionally, advocacy was needed at the policy-level for Social Security coverage.  Several studies determined that early detection of visual, auditory, or motor development delays would prevent higher cost interventions and burdens in the long-run, thus justifying minimal year follow-up for high risk cases (Rosero, n.d.). By properly educating and training stakeholders with available evidence, implementers and advocates addressed misinformation and negative perceptions regarding KMC. Importantly, the core elements of KMC delivery—position, feeding, and early discharge—were culturally appropriate per local customs and religion for initial roll-out (Rosero, n.d.).

Scholars and practitioners have further investigated barriers and enablers to KMC implementation across contexts to develop appropriate recommendations (Cattaneo, 1998; Charpak & Ruiz-Peláez, 2007). It is seen that in addition to healthcare barriers faced, sociocultural factors exist and may impede successful take-up of KMC in other settings at varying degrees.  The requirement of diapers in settings where it is not traditional practice, mothers’ limited privacy and resulting exposure, perceptions of extra work for staff, restricted participation of father, discomfort of the mother, lack of using caps and socks in warm climates and the effect of continuous skin-to-skin contact on mother’s other duties or daily routine, have all been identified as practical barriers (Charpak & Ruiz-Peláez, 2007; Chan, 2015; Chan, 2017). For example, KMC’s interference with “obligations related to mother’s daily routine” was reported from Zimbabwe, Uganda, and Guinea (Chan, 2015). Fundación Cangaru has received more than 35 developing countries for KMC training; however, there has been special difficulty with northern Africa. One interpretation is that the promotion of the active role of the father may be unattractive or difficult to put into practice in settings where pregnancy, newborn care, and the first years of life are private property of the women (N. Charpak, personal communication, 7 December 2018).

 Additional factors identified in the literature that influence KMC implementation include buy-in, support and empowerment, time, medical concerns, access, and cultural norms (Chan, 2017). Therefore, coordinated actions and consistent communication among national and local leadership is needed to support essential health systems and financing requirements for KMC (Chan, 2017).

Is KMC Cost-Effective?

Given the simplicity of KMC, a common misconception is that little funds are needed to effectively and appropriately administer the treatment.  Parents become major caregivers of the infant, leading to decreased economic productivity.  Furthermore, implementation requires parent coaching and frequent follow-up after discharge in specialized clinics. Still, the analyses performed on implementation all over the world have been promising.

Observational studies of implementation in 12 Nicaraguan facilities estimate that US$230 000 would be saved annually (Broughton, 2013) by formally instituting KMC.  Further studies on implementation in India estimated that hospitals saved US$570 per LBW infant treated with KMC compared to traditional intermediate intensive care (Sharma, 2017).  Most importantly, an incremental cost utility analysis on a randomized controlled trial in Bogotá, Columbia proved that KMC is significantly more effective and less costly than traditional care (Ruiz, 2017).  While these results are specific to regional hospitals and their systems in place, the trend remains the same all around the world.  Moreover, these results likely underestimate the cost-effectiveness of KMC.  20 years after its first implementation, we are seeing KMC significantly increase brain development and social skills – both of which have potential impact to improve economic productivity (Charpak, 2017).

Where is the money coming from?

Two of the United Nations’ eight Millennium Development Goals (MDGs) focus on improving maternal health and reducing child mortality.  This era of MDGs has helped mobilize funding in areas to aid with the implementation of KMC.  For example, USAID and their Healthcare Improvement Project (HCI), in coordination with the Ministry of Health in Nicaragua, have been heavily involved in the implementation of KMC in rural hospitals of Nicaragua (Broughton, 2013).  Beyond 2015, there has been continued support in the form of programs such as the “Every Newborn Action Plan,” which aims to treat 50% of low birth weight infants with KMC by 2020 (Every Newborn: an action plan to end preventable deaths, 2014).  This plan has been largely funded by the Global Financing Facility (GFF) trust fund, which was initiated with a pledge of $875 million from the governments of Canada and Norway, as well as the Bill and Melinda Gates Foundation.  Since its initiation, many other foundations have supported this trust fund, such as GAVI, The Vaccine Alliance, The World Bank Group, and other bilateral agencies (Reaching the Every Newborn National 2020 Milestones, 2017).  Overall, their goal is to mobilize over $18 billion in funding between now and 2030 (The Global Financing Facility 2016-2017 Annual Report, 2017).

While these external agencies have limited funding, the simplicity of KMC offers unique sustainability if implemented correctly.  As seen in Nicaragua, involving national health agencies in the implementation allows for the development of sustainable, ‘horizontal’ plans to maintain proper care.

Future Implications

Scale-up from Colombia to Asia and Africa – the difficulties experienced with KMC implementation:

In Latin America, since its inception at the Maternal Infant Institute (IMI) of Bogotá, Colombia in 1978, scale-up has been achieved through the SODOTO model of dissemination. As discussed above, teaching has been utilized to disperse the knowledge on KMC in most Latin American countries and certain European hospitals (Bergh, 2012). This model of dissemination is also being used to implement KMC in sub-Saharan Africa and South Asia (Bergh, 2012; Bergh, 2016), where 60% of all preterm births occur (Blencowe, 2013). These regions would benefit the most from implementation of the KMC method; however, uptake has been less than optimal.

Several aspects of implementation strategies explain this lack of progress. The model of dissemination engenders intermittent funding, usually from non-governmental organizations (Bergh, 2016). Dependence on these donors can seriously halt the growth in implementation of KMC. Furthermore, a shortage of advocacy leaders in these countries hinders the spread of the intervention from lone facilities to a more organized scale-up at a national level.

The majority of African healthcare systems are overwhelmed with a high burden of infectious diseases combined with the growing reality of non-communicable diseases. Moreover, financial decision-makers are not involved enough in discussions about mother and child health and are therefore unable to request more resources for KMC for its scale up in the health-care systems (Bergh, 2016).  The SODOTO model of dissemination comes with good intentions, but generates vertical KMC programs that are too expensive to sustain. Stakeholders need to propose ways in which KMC can be implemented in the existing systems of care for newborns (Bergman, 2015).

Is facility-based KMC sufficient for impact?

Although there is a consensus that hospital-based KMC is effective and sustainable, there are still questions surrounding the true impact of this approach. Most births in South Asia, Southeast Asia, and sub-Saharan Africa take place at home. In the two lowest wealth quintiles, more than 70% of all births are home deliveries, and at least half of them are unattended (Montagu, 2011). The potential impact of facility-based KMC fades when keeping these numbers in mind. Facility-based care is important, but to tackle the bulk of the problem that is worldwide neonatal mortality, it is paramount that all efforts are focused towards a community-based approach.

More research is needed to determine the efficacy of the community-based kangaroo method (CKMC). For now, studies do not seem to indicate that CKMC is feasible in remote or low-resource settings. One-randomized trial reported missing birth weights, a weak implementation, and no significant difference in mortality between the intervention and control groups (Sloan, 2008). However, evidence is limited and many more trials are required to truly assess the impact that CKMC could have in maternal and child health and determine the right formula to adopt (Barros, 2010).

Official protocols do not recommend the KMC approach for unstable preterm neonates. Nonetheless, a randomized trial on unstable newborns seems to indicate that KMC could also have significant risk reductions in mortality in that group (Bergman, 2015). These results are promising, but more similar studies are necessary to gauge the potential impact of KMC on unstable infants.

Conclusions

Overall, the implementation of KMC has led to a reduction in risk of mortality in LBW infants by 40%, a reduction in nosocomial infections by 58%, and savings of approximately US$570 per patient (Conde-Agudelo, 2014; Sharma, 2017). However, in the lowest wealth quintile of the world, more than 70% of all births are home deliveries (Montagu, 2011).  The potential impact of facility-based KMC fades when keeping these numbers in mind.  Furthermore, implementation of KMC in Africa and Southeastern Asia has been less than optimal. The SODOTO model of dissemination comes with good intentions, but generates vertical KMC programs that are too expensive to sustain (Bergman, 2015).

Coordinated actions and consistent communication among national and local leadership is needed to support essential health systems and financing requirements for KMC (Chan, 2017).  Stakeholders must be involved in the discussion of ways to implement KMC in existing systems of care to provide sustainable treatment.  Furthermore, research is required to evaluate the impact of community based KMC, where it could potentially reduce the most premature neonatal deaths.
