Each Friday for the next three weeks, the Tanzania EWH team will work at Mount Meru Hospital just outside the heart of Arusha.
The Tanzanian health care system consists of larger referral/consultant hospitals such as Kilimanjaro Christian Medical Center, regional referral centers covering several districts, and smaller hospitals covering one district each such as Karatu Hospital.
Mount Meru is a regional hospital with departments for obstetrics and gynecology, pediatrics, surgery, out-patients, and units for ophthalmology and dentistry. The hospital also has a laboratory and an intensive care unit. The hospital typically sees 500 patients per day on an outpatient basis and admits approximately 250-290 patients every day.

Generally there is a fee to be seen by a doctor at Mount Meru; however, as a public hospital, they are obliged to serve all people, and will provide free health care to those who cannot afford it.
The typical population served by the hospital consists of farmers, pastoralists or industry workers. These are families that earn a low to middle-class income. Some of those who work in the outskirts of the districts covered by Mount Meru Hospital (for example people coming from Ngorongoro or Longido district) have nine hours travelling time to the hospital. Others simply can’t afford the cost of transportation. As a result, acute patients, especially pregnant women and children, often reach the hospital too late for doctors to do anything.

According to hospital staff, the largest barriers to provide health care services in Tanzania are lack of capacity to handle all, but especially acute patients, lack of funding and lack of accessibility to medicines, supplies and health care technologies. These issues are more or less apparent in all across governmental Tanzanian hospitals from the district level up to referral/consultant levels. Handling acute cases is a particularly large problem at district hospitals, which is why regional hospitals like Mount Meru experience a very high occupancy rate and a high number of patients, that do not reach the hospital in time for an ideal outcome of their treatment.
At Mount Meru Hospital, one challenge in meeting the demand is the large amount of donated equipment of which only about half is currently functioning. The entire region has just one biomedical engineering technician (BMET), Mr. Sharif Rajabu Kishakali.As of early 2015, he is the first ever BMET at Mt. Meru Hospital. He is currently working on a preventative maintenance program for the hospital’s equipment. The attached pictures are a collection from the projects he is currently working on.

As described extensively on this blog, working in a developing country hospital is not always easy.
In effect, it always results in a great sensation of success, when one suddenly finds a hidden stash of valuable – yes – cables. Exactly that happened when our group found the ECG’s cables and power supplies shown in the pictures below.
Box of Cables
In a storage room at the emergency department of the hospital we found 7 vital signs monitors, 7 Power supplies, 2 pulse-oximeters and 3 ECG cables in woking condition. Unfortunately, all remaining cables for the seven machines were broken, an example of which (an SPO2 sensor/pulse-oximeter) is shown here.

ECG cables broken.
From all the parts we had an fixed we managed partially assemble 5 working Vital Signs Monitors: Two of them were put back in to service with pulse-oximetry and ECG working, 3 of them with ECG only. Unfortunately the department didn’t have any compatible blood pressure cuffs, so we would have to buy new ones, just as we wouls need additional pulseoximeters and ECG cables.
Vital signs monitors are fairly simple pieces of medical equipment, however the cheapest completely refurbished set found on eBay that is corresponding to these machines is $3.503.
Thus having these pieces in working condition would have an extremely high value to Roosevelt Hospital. Meanwhile the cheapest prices on eBay for replacement parts, that we need to put all of these vital signs monitors back into service, are found for $24 (SPO2) + $54.50 (ECG) + $12.5 (Blood pressure cuffs).
In “How to repair shielding on ECG cables and leads” I described how we we repaired three sets of cables. The fixes were good, but not perfect in that we did make the cables work, but the signal was still somewhat noisy, for which reason the machines couldn’t have been used in surgery and detailed diagnosetics – rather they were useful for general “simple” monitoring.
Considereing the fixed cables as being in working condition (a somewhat noisy signal is, after all, better than no signal at all), we now just needed 2 ECG cables, 5 SPO2 censors and 7 blood pressure cuffs to make all of these machines work.
The total cost of this according to the prices on eBay would be just $321, although with used parts.
Considering that a completely new refurbished set on eBay costs 3.503, the value of these equipments reach $24521 in order to buy seven of these machines.
By repairing these machines our team achieved 79x value for money (even though the fix wasn’t perfect).
Now, I thought this story would end here, when, out of the blue, I received an email from Mr. Juan Fernández at Spacelabs Healthcare in Latin America, who wrote that they would be able to send the broken parts to us — free of charge! We could now make all the machines work perfectly (with no noise on the line). My collegue in Guatemala, biomedical engineer and expert technician Mr. Joe Leier will receive and bring this donation to Roosevelt Hospital as soon as possible.
I want to thank the people, that have been a part of saving these machines: my collegues Ms. Rebecca Avena and Mr. Joe Leir and Mr. Juan Fernandez at Spacelabs. We at EWH and Roosevelt hospital we are extremely thankful for this donation, which now means that Roosevelt hospital has 7 fully refurbished, high quality patient monitors working in their emergency department.
Discovering that the monitors and power supplies work
Global Medical Aid (GMA), an aid organization from the Capitol Region of Denmark, was given broken medical equipment and therefore forced to spend their resources separating life-saving medical equipment from useless machines. Unfortunately, not all organisations perform this vital quality control: many donations end up as nothing more than piles of junk at the world’s poorest hospitals.
Medical equipment is extremely valuable and has the potential to significantly improve health care in developing countries. In an effort to aid the world’s poorest health care systems, western hospitals often donate used medical equipment when updating their inventory.
Unfortunately, donations often don’t have the intended positive impact. An example of how donations can end up causing more harm than good was featured on the main Danish news channel DR1:
The news story was on national Danish television and radio.
It is described how regional politicians of the Capitol Region of Denmark did not set aside resources for testing of equipment donations before the machines were given to Global Medical Aid (GMA). GMA had to spend a large amount of financial and human resources on separating useful pieces from broken ones — resources that should have been spent on the transportation of equipment to developing countries. (See translation of the full story at the end of this post).
Not all aid organisations pay third parties to test the quality of their donations as GMA does. Many aid organizations simply ship malfunctioning equipment directly to developing countries without any quality assurance whatsoever.
An example of this is illustrated in the pictures below from Roosevelt Hospital in Guatemala City, taken on the the 30th of December 2014. I am currently working at the hospital with Engineering World Health as part of a six person team of students and professionals from Rochester Institute of Technology, George Mason University, Marquette University and the Technical University of Denmark. We are based at Roosevelt Hospital in Guatemala City with the aim of placing broken donated equipment back into service.
Already during our first day at the hospital we found vital medical equipment out of use: 14 haemodyalisis machines, 7 vital signs monitors, 4 anaesthesia machines and an incubator. The well-meaning donations are left as junk in the “equipment graveyard” in the back of the hospital.
Another example of failure to target donations properly is shown in the following picture from the same hospital, featuring the pictured dental chair, which is still partly contained in the original wrapping, indicating that the chair has most probably never been used.
Unfortunately, the problem we are facing at Roosevelt Hospital is not unique. It is seen in developing countries around the world. Leslie Calman, CEO at Engineering World Health, summarises the issue as follows:
“The donation of medical equipment is a generous and well-meaning outpouring of aid, intended to strengthen health care systems, reduce human suffering and extend life-saving remedies to millions. But if not done with care and attendtion to local conditions — including the capacity of local hospitals to install and maintain the equipment — the generosity may not live up to its donors’ good intentions. The Secretary General of the United Nations has stated that as much as 70% of essential medical equipment is not functioning in the developing world. Coupled with equipment donations should be an investment in training a local workforce to maintain and service the equipment. This would create local jobs, build skills, improve the environment, and create the conditions in which healthcare can be safely delivered.”
The magnitude of harm caused by faulty equipment donations goes largely unnoticed. To illustrate this, consider the following: According to World Bank, the Danish health care expenditure in 2012 was 11.2% of Danish GDP, accumulating to $6,304 per capita (the corresponding number in the United States is 17.9%). This means that $6304 is spent on health care for every single one of Denmark’s 5.6 million citizens.
$34.65 billion is spent on health care in Denmark every year. Contrary to popular belief, this money is not spent on the high salaries of doctors. Based on the average yearly physician’s salary in Denmark of $85,000 and nurse’s salary set at $54,000, only 18% of the Danish health care expenditure is spent on salaries. The major part of the remaining $28.14 billion is spent on hospital infrastructure and the extremely valuable medical equipment.
My point is not that poor hospitals don’t need equipment donations. Rather, the important aspect to realise is that the donation of advanced technologies is extremely complicated. Resource-poor health care systems are in need of expertise from professionals who understand advanced health care technologies and the logistical complexity behind donations.
The fact that a vast amount of broken equipment is sent off to fill up the words poorest hospitals without ever being used is ethically irresponsible and indefensible. It is essential that local health care workers, departments, and hospitals ensure that well-meaing donations actually end up fulfilling their life-saving purpose.
Translation of the original story:
Danish hospitals donate used medical equipment to alleviate poor countries. However, aid organisation warns that the equipment may be dangerous to use.
In a corner of Global Medical Aid's storage halls in Birkerød you'll find more than 30 infusion pumps. They are donated from hospitals in the Capitol Region and should have been sent to poor countries in Africa, but as it turns out, this equipment is completely defective.
The relief organisation Global Medical Aid sends hospital equipment to poor countries around the world. They are now accusing the Capitol Region for using them as a landfill.
The reason is that the organisation has been given an abundance of used medical equipment that does not work at all. Everything from anaesthesia machines to infusion pumps and defibrillators have turned out to be broken.
"We have obviously been treated as if we were a landfill site, where hospitals could get rid of the equipment they have been storing in basements for years" says Hans Frederik Dydensborg, the president of Global Medical Aid (GMA).The politicians of the region have now decided that medical equipment is to be donated in an ethically responsible way. According to GMA, it is directly unethical when hospitals donate equipment that doesn't work. GMA has incurred large expenses in separating working pieces from broken ones -- money that should have been spent on bringing the equipment to the world’s poorest countries."We have had large amounts of unnecessary expenses, with the consequence being that we haven't been able to send off the containers as expected" says Hans Frederik Dydensborg.In the Capitol Region, the chairman of the IT and debureaucratisation committee, who is responsible for recycling medical equipment, is concerned about the fact some donations have proven to be useless."Of course the equipment must have a certain standard, and of course it to be in a condition such that it can be used" says Lise Müller (Socialist People's Party).To avoid faulty donations in the future, the Capitol Region is now creating a storage hall in order to collect used equipment from hospitals and check it up for errors and deficiencies before they are sent on to aid organisations.In the region of Mid-Jutland, they have good experiences with a corresponding scheme."I am sure that we can find people who could find use of the equipment. If they don't, we will have to throw it out. But of course we have to learn from this, that the equipment we donate is of the right quality" says Lise Müller. The new storage halls will cost about DKK 2 million (USD 330.000) a year to maintain and the money will be found in the 2016 budget of the capitol region.
Noisy ECG signal found when using the broken cable
Buying one new ECG cable for a patient monitor would cost $51 if purchased on eBay. However, it is feasible to fix the ECG cables and avoid the cost of purchasing new parts. In order to do this, we performed three simple steps:
1) Wrap foil carefully around the ECG cables.
2) Ensure that the foil is electrically connected to the ends of the original ECG cable shielding.
3) Wrap the foil tightly in electrical tape
Wrapping the cable in aluminum foil.
Fixating the aluminum foil tightly with electrical tape.
The improved signal with aluminum foil.
The photo on the right shows the resulting ECG signal. The ‘p-q-r-s-t” sequence of a normal ECG signal can be seen on the screen.
The result is still not optimal, as there is residual noise interfering with the signal. Our group is currently investigating ways to make the shielding more effective so that the foil is optimally electrically connected along the entire length of the cables.
During our first day at the hospital we’ve been working on two projects:
The Vital signs monitors.
The emergency department of Roosevelt hospital has received seven vital signs monitors as donations. They suspect the machines should be working fine, however the cables for measuring oxygen saturation, ECG and oxygen saturation are broken. Unfortunately we cannot test these machines as the power supplies are missing.
Furthermore only managed to collect one set of cables in condition good enough for them to be reapaired and unfortunately buying new ones would cost hundreds of dollars per machine.
For now the strategy will be to get a DC power supply for the machine as quickly as possible (18 V, 2,7A) and then we will try to get just one machine up and running.
The wire shielding was completely tangled up so we had to removed it.
Unfortunately we can’t currently test the machine as we need a power supply. We should be able to buy thit on day 3 at the hospital.

The 13-17 dialysis machines
I have seen thirteen machines with my own eyes, some say however that the hospital has 17 Dexter 1550 type dyalisis machines. We started out trouble shooting two of the machines that looked as if they were in a proper condition.
The machines are quite old old but some of them are in a surprisingly good condition. Currently the haemodialysis department is renting machines from an external company, which is expensive, so it is our hope that we can help the hospital by getting their own machines working and thereby save some expenses.
Unfortunately we are currently in doubt whether or not the consumable products are necessary to use the machine are available.
For now however, we are still testing the machine!
Stay tuned for the coming updates for the continuation of these projects and the initiation on the baby-bottle project!
On the first day of the 2014/15 Guatemala Winter institute we had an introductory morning briefing to talk about program details, safety guidelines, culture shock and logistics.
Later on that day we would proceed to Roosevelt Hospital in Guatemala City, one of the the largest hospitals in Guatemala.
As we arrived, Head of the biomedical engineering department at the hospital, Hector, showed as around and introduced us to several different projects that the EWH engineering team could work on during our three weeks.
The following is a list of the projects we found on the first day at the hospital:
1) 14 Dialysis Machines: In the basement of the hospital we found about 14 dialysis machines out of order. If can put these back into service it will be vital to find and teach a technician at the hospital about the machines as they require continuous maintenance. See picture in the gallery below.
2) 7 vital signs monitors: These machines actually work perfectly (according the emergency department staff) but the cables are destroyed. We are looking into getting a hold of all the cables from the emergency department so that we can find out if we can fix them.
3) The baby bottle project: The baby bottle cleaner of the hospital is broken. 1500 babies need to be fed everyday there are 45 different recipes for the baby food depending on the state of the babies. For example prematurely born babies are prescribed more oily food. Thus the department staff must manually clean 1500 bottles a day. They don’t have any proper substitute tools and it gets really difficult to clean the baby bottles. See pictures in the gallery below.
4) Tortilla machine (kitchen): This machine is working but the tortillas are sticking to each other and one side was burned more than the other. Sometimes the tortillas are cut in half. In effect a lot of dough is wasted. See picture in the gallery below.
5) Bread oven (kitchen): Issues with the temperature regulation.
6) The outside yard with broken medical equipment: Most of the equipment has been outside in the rain and it has become rusty. It is likely though that there are several valualble spare parts in the “junk yard”. See pictures in the gallery below.
Additionally a pre-trip equipment assessment was made by biomedical Joe Leier who is assisting EWH 2014/15 Winter Institute.
7) Three additional vital signs monitors.
8) Seven suction pumps.
9) Three defibrilators were found, condition onknown.
10) Five Electrocardiographs.
For now we will start working on projects 1, 2 and 4. I will follow the progress of the projects here on this site. Stay tuned!
This dental chair was donated to Roosevelt Hospital in Guatemala and as seen on the picture, it has never been used: Part of the original wrapping is still on there.

Shortly before we left the KCMC this August, we found out that it was not rare for hospitals to be lacking various equipment in paediatric size. In consequence it would not be possible to measure the oxygen saturation and blood pressure of children. In some cases lack of paediatric size tubes made it impossible to intubate children in need of a ventilator to assist their breathing.
Most of these products could probably be made pretty easily with a bit of creativity. This should give ideas for some design projects for most biomedical/design engineers.
We had a small budget for our various projects from the EWH and we decided to spend what we had left to buy blood pressure cuffs in paediatric size and clip-on pulse oximeters for the paediatric department at KCMC.
Around the world LEGO Company is famous for inspiring creativity through play. Nowadays LEGO is also being used widely for educational purposes. In Tanzania, I found a new use of LEGO that I would have never imagined possible.
This summer I was one of six students from EWH DTU participating in the annual Engineering World Health Summer Institute in Tanzania. We brought 27 kgs of LEGO bricks from LEGO Charity with us. During our stay, we found schools and orphanages to which we could donate the LEGO bricks.
In one case, however, the LEGO bricks could be used for purpose more serious than pure entertainment. I was fortunate enough to meet Dr. Marieke Dekker, currently the only paediatric neurologist in all of Tanzania – a country with a population of almost 50.000.000.
Paediatric neurologist Marieke Dekker
Dr. Marieke Dekker works with hundreds of children with serious neurological disorders in her work. As a neurologist she uses the LEGO bricks to test fine motor skills and cognition of the children. She is able to asses their development and at the same time give them a once in a lifetime gift that brings great joy. Many Tanzanian children have never seen, let alone owned, toys before:
According to Dr. Marieke Dekker, “LEGO bricks are a great success, especially here, dealing with children suffering from neurological disease. Neurological conditions are often well visible and they are known to cause stigmatisation in African society – it is a huge social problem.”
At the paediatric ward of the KCMC children received LEGO bricks as a gift.
Children were given LEGO bricks as a gift #1
Children were given LEGO bricks as a gift #2
Paediatric Neurologist Marieke Dekker uses LEGO bricks for occupational therapy at her clinic at the Kilimanjaro Christianity Medical Centre in Tanzania.
The stigmatisation of these conditions, even by family members, complicates many children’s access to care. As Dr. Marieke Dekker points out, cerebral palsy is the most common paediatric neurological disorder in Africa. The disease is primarily caused by poor perinatal circumstances and healthcare. The severeness of cerebral palsy is varying results in cognitive, behavioural and learning disabilities. Children with less severe cerebral palsy have proved to be a very successful target group for LEGO bricks.
The LEGO bricks allow doctors like Marieke to assess motor skills, as it “‘breaks the ice’ in the patient-therapist relation and the ultimate joy is to be given the toy upon going home.” says Marieke.
In many cases, the cerebral palsy can be devastating, rendering a child dependent on care around the clock. This group is unfortunately also very common in Africa, mostly concerning school-age children with spinal cord problems. Due to dangerous traffic, falling from trees (harvesting fruits, a major part of African diet), tuberculosis and other infectious diseases, a disproportionate number of children are paraplegic and wheelchair-bound for life.
“Since there is no rehabilitation medicine in Tanzania, they remain in-patients until the family cannot pay the hospital bill anymore, or until they die from pneumonia or infected pressure sores. Many of these children were given LEGO bricks. They built, rebuilt, remodelled and rearranged… it gave them and their caretakers a spark of joy in a circumstance of misery.” says Marieke Dekker.
Marieke’s patients truly benefit from using the LEGO bricks in the clinic professionally as well as psychologically. It means infinitely much to children to whom such toys would never be affordable, let alone available.
Marieke, the EWH DTU chapter, and I wish to continue this collaboration by bringing LEGO bricks with us to the Summer Institute in Tanzania in years to come!

It is now a little more than a week ago that I returned from and unforgettable journey to Africa. It’s been such a journey that expands horizons, gives new perspectives, creates new visions and changes beliefs and values. During my stay I worked for a month at local hospitals, an experience that was different in so many ways from what I had expected.
Prior to our placements at local hospitals the students of the 2014 EWH summer institute (myself included) took part in a month-long educational course on “Engineering in the Developing World” and an introductory Swahili course – a program which proved to be of considerable advantage as we were soon to develop a trusting relationship with the departments we would come to work for.
After this first month of education I was moved to my placement along with my group, which besides myself consisted of a student from Duke and one from Harvard. We were to work in two hospitals: Kilimanjaro Christianity Medical Centre (KCMC) and Mawenzi Hospital, both situated in the town of Moshi, Kilimanjaro region.
The KCMC is one of the largest and most prestigious institutions in Tanzania and has a biomedical engineering department consisting of 30 engineers and technicians. Despite good will and hard work from the department, it was obvious that we could do much in both hospitals, just as we could learn a lot from them. Our group alone repaired more than 60 pieces of equipment during our stay. Overall, this year’s EWH summer program returned 4,200 pieces of equipment amounting to 8.6 milion according to the latest figures from EWH.
If I was to draw one conclusion about medical equipment in developing countries today, I would say that it simply should not be allowed to donate without informing properly about that specific piece of equipment in the local language (or in English, at the least):
In so many places we found rooms and whole warehouses filled with piles of medical devices. To our surprise, very often these devices could be put back into service by simple mechanical repairs. We even found completely new operating theatres that could not be used because they were packed full of unused equipment. I was left behind wondering if donations do any good at all – or if they do more harm than good. During our month at the hospital we slowly started to learn the reasons why these equipments weren’t in use: How were people supposed know how to use a piece equipment, if they had no manual for it? Or how could they use a machine, if the user interface was in Dutch or in German? When a repair was to be done after all, many reported difficulties and bureaucratic systems when having to acquire replacement parts, such as a lightbulb for a microscope.
The type of problem that could arise when departments were not provided information about new technologies became clear to me one day at the KCMC, when our group was asked to repair an Infant Warmer from GE. We were told the following: The department had received a completely new machine and put it into a small room where they normally observed newborns in the early hours after a birth. But when the staff began to use it, the machine heated the room up to a temperature so high, that it was unbearable to stay in there.
The solution turned out to be immensely simple: the skin-temperature sensor had mistakenly been placed under the bedside, and had to be moved to the skin of the newborn – otherwise the device would constantly work to achieve a temperature of 35.5 degrees under the bed instead of on the baby’s skin. Thus the machine was heating on and on (and on…).
After having cleared out this first misunderstanding, we explained that the machine could not, as some thought, be used to take X-rays images, but that it merely contained a tray for a detector plate so that you weren’t forced to move the baby around unnecessarily, and that the machine could not calculate an APGAR-score, but that it contains a stopwatch simply to help you with the task. The problem wasn’t lack of education or ability to understand how a machine works. It was simply the fact that people were not provided the necessary information. Even if some information was provided, it was not done properly: How is a nurse going to read a 500 page manual, while working in a ward full of women in labour? Seeing this and other similar cases, one of our main focuses became developing quick start guides in order to provide departments with a fast and simple way of knowing how to use a device.
Another typical issue that we encountered was how departments virtually never took advantage of vital signs monitors and ECG’s because they had run out of the necessary electrically conductive gel. There are a number of alternatives to conductive gel – in principle anything that contains electrolytes, for example aloe vera or ketchup, can be used. It should have been obvious however (as I did not first think of), that most doctors and patients do not want to use these methods, as they are uncomfortable and inconvenient. I remember explaining to a doctor how he could make his own electrically conductive gel using water, flour and salt. His response: “Is that really recommended?”. Imagine his reaction, had I recommended him to use ketchup. In addition, many Africans are proud people to whom one can and should not just offer anything (just as one would probably not do anyone at home). Therefore, developing a gel that is more likely to be used clinically, and in addition could be produced cheaply using local materials, would be an example of a simple and small, but valuable project for developing world hospitals (while you can find alternatives to conductive gels, I still haven’t seen one that actually looks like the gel that is used in clinics). Notably the KCMC already had the means to produce their own ultrasound gel (which is acoustically and not electrically conductive) so they shouldn’t be too far away from being able to produce their own conductive gel too.
This and many other projects are still to be carried out to make the daily life at a these hospitals run smoothly. Here I have given just two examples of what it can be like to work in the developing world. So many ways remain in which one can help this parallel world of ours, in which resources are so scarce that we are constantly forced to think in new and innovative ways to provide the best possible health care for the all people.
