When “go-local” doesn’t work: sanitary napkins in sub-Saharan Africa   Leave a comment

7 years ago, an enterprising Harvard student, Elizabeth Scharpf, began a project to produce sanitary napkins using local workers and local materials in sub-Saharan Africa. Although difficult to quantify, the amassed evidence has suggested that many women in developing countries– particularly school-age girls — are routinely sequestered and miss multiple days of school each month because of the lack of hygiene products to use during menstruation. This issue has been long ignored largely because of the associated stigma around a woman’s menstrual cycle in conservative societies and the lack of health officials familiar with women’s needs. Sustainable Health Enterprises (SHE), the company founded by Sharpf, was an attempt to a) address the needs of rural women through a locally available commercial product AND b) provide a self-sufficient business model to entrepreneurial women in these countries.

The basic model has been to first find local entrepreneurs interested in starting a local sanitary napkin production operation. The raw materials for these sanitary napkins are then sourced locally using banana tree fiber, a waste product of banana harvesting, as a substitute super-absorbent material. The cost savings on materials and production help reduce the cost per pad from US$0.11 to US$0.07.Local women are then trained to produce these with small table-top workshops that can be used in their private homes. These are then collected by the local entrepreneur and sold in markets or with door-to-door sales models.

SHE’s success to date has been mixed. Between 2009 and 2011, Scarpf used funding from Echoing Green and Harvard Business School to setup the first franchise model of banana fiber-based sanitary napkin production and distribution in Rwanda. However, using the available public information on SHE’s website and blog, the latest updates dated August 3, 2012 suggest that company is just now completing its supply chain and brand strategy. The largest hurdle seems to have been that the uniqe selling point SHE pads offer — their attractive lower price — are exactly why consumer demand from Rwandan women has not been strong. In a critical oversight, Rwandan women who cannot afford imported pads would rather use their existing coping mechanisms in a pad-less world than use SHE’s product. Although SHE is actively working through these issues and is currently completing a redesign, SHE has yet to prove its model for a new sanitary napkin for the low-income communities.

A particular concerning trend is that efforts to provide locally-produced sanitary napkins have been increasing even though the existing businesses have yet to identify a succcessful business model. At the the University of Oxford’s 2012 TATA Ideal Idol business plan competition in March, one of the finalist was BaNaPads, a similar sanitary napkin effort being attempted in Uganda. No evidence suggests that these me-too ventures are finding solutions to the problems that racked earlier efforts. Although there is a certain attraction to local production and women’s empowerment through independent income generation, the social entrepreneurship and global health communities should be self-critical to such unproven models.

While the work of the organizations above is commendable, none of these efforts have seem to realistically questioned if multinational corporations are already providing female hygiene products in the most financially sustainable way. Patricia O’Hayer, Unilever’s Vice-President for Communications and CSR, challenged the development community in a recent Oxford-based debate to avoid automatically assuming that there was something intrinsically better about local production versus global mass production when it came to making consumer healthcare products. Procter & Gamble and Unilever may be unapologetically “big business,” but their ability to reach economic scale and provide a safe, reliable product may be unmatched in this product category. Entrepreneurial efforts such as these must be compared to existing ways of doing business if they are meant to contribute to societal value creation.

Disclosure: In early 2012, I informally worked with a team from  Procter & Gamble on shared interests to bring health-related retail products to rural communities in rural Kenya. There was no material remuneration from this engagement.

FoetoH – Good science. Good medicine?   1 comment

I recently came across FoetoH, a fetal heart rate monitoring device that has been developed at the University of Oxford. Unlike other forms of fetal health monitors, FoetoH is designed to be used by laypeople and in a real-time manner. Rather than giving health information output in complex jargon or graphs, the device provides a stoplight-style assessment (green, yellow, red) of a developing fetus’ current health. The scientific breakthrough was developing an exercise belt-like device (think exercise heart rate monitors) that a mother-to-be wears all the time that communicates with a handheld unit (or iPhone app) which facilitates data storage and interpretation.

The idea of FoetoH is attractive because of its synthesis of the latest technology trends (i.e., mobile-based health applications, user-oriented design) and advanced health monitoring devices. The marketing materials of FoetoH are excellent and describe this device as potential breakthrough to help address the more than 2 million stillborn babies born each year around the world. The basis of this claim is that mothers who know their pregnancy is in trouble (indicated by a “yellow” or “red light” on the device) could receive emergent medical care to improve fetal outcomes.

Unfortunately, such a simplified product and health solution obscure some major logical flaws in their existing argument. For FoetoH to contibrute to a reduction in worldwide stillbirths, the device needs to prove itself to be more than just effective at measuring fetal heart rates. FoetoH’s founders need to be able to demonstrate that identifying changes in fetal heart rates is an effective way of identifying AND preventing still births. Why do I raise this issue? The limited data available on still births demonstrates that the majority of still births are due to genetic and environmental insults that go well beyond impaired cardiovascular support of the fetus. Many of these stillbirths are due to unknown¬† genetic causes, infectious disease, or severe malnourishment, and fetal distress (erratic fetal heart rates) is an end-stage sign of imminent still birth. In these cases, last-minute emergency care would have virtually no chance of preventing “fetal demise” (technical term for still birth). It is also unclear that FoetoH’s real-time monitoring is any more effective than current guidelines for antenatal care which include regular physician visits and routine ultrasound scans at pregnancy milestones.

Moreover, it is unlikely that most mothers at risk for stillbirth would be able to gain access to the FoetoH device. Its currently reported cost of manufacturing is approximately $80. A public sector price is likely at least twice as expensive with a market price even more. Given that the vast majority of stillbirths occur in impoverished women from developing countries, the target population who could potentially benefit from such a device would be unlikely to be able to afford it. Even if such devices were provided free of charge to high-risk mothers, the limited benefit of using the device I raised in the prior paragraph would likely outweigh the high cost to health systems.

These issues are not lost on healthcare device makers familiar with the product. At Oxford’s recent TATA Idea Idol business plan pitch competition – where FoetoH was a finalist – judge Will Chadwick of TATA Interactive Systems noted that the only realistic market for FoetoH were overly concerned mothers from the industrialized world who were willing to pay for a device that provided peace of mind rather than a clear-cut medical benefit over existing practices.

In fairness to FoetoH, its TATA Idea Idol team went on to win this year’s competition despite Chadwick’s misgivings (so someone clearly thinks FoetoH has something going for it). In the end, the science and potential commercial market for the device were convincing enough to beat out a number of strong competitors. FoetoH is a useful reminder for clinicians. Sound science and commercial availability do not make good medicine. Healthcare providers have to always maintain a critical eye and question new healthcare good and services to ensure that they are consistent with the individual provider’s aims and means of care as well.
