ethiopia has one of the worst maternal mortality ratios in the world , at 673 per 100,000 ( range 54810).1 concealed within this figure is a marked urban / rural split . the 2011 ethiopian demographic health survey carried out by the ministry of health showed that in the capital , addis ababa , 82% of mothers deliver in a health facility whereas in the amhara and afar districts that are largely rural , the rates are 10% and 7% , respectively.2 there are many problems involved in overcoming this . for example , in the amhara region of ethiopia with a population of over 20 million people there were 16 hospitals in 2010 and only six of these could reliably deliver emergency obstetric care . lack of facilities combined with costs that were cheap in global terms ( us$5 ) , but prohibitively expensive for the local population , poor roads and communications , most women can not attend a hospital for their delivery . as a result only 10% of women in ethiopia receive help from a skilled delivery assistant with some estimates of 96% women delivering at home in some areas of ethiopia.3 the ethiopian government has tried some programs to increase the human resources to deliver emergency obstetric care ( emoc ) in those remaining hospitals . the current scheme is a 3-year master of surgery course available not only to medical doctors , but also to health officers . the master of surgery course not only covers emergency obstetric management , but also emergency surgery . however , it will be many years before the shortage in labor is resolved due to the number of candidates being trained versus the number required and the length of time it takes to train each candidate . in the meantime , the amhara regional health bureau of ethiopia requested overseas help to overcome the labor shortage by placing volunteer teams of obstetricians and midwives in rural hospitals to help provide the service and also train local staff members in emoc . the objective of the study reported here was to assess the impact of placing volunteer medical teams within the ethiopian government hospital system in targeted hospitals on maternal morbidity and mortality , before , during , and after the intervention . it is a government district hospital that was opened in the year 2000 to service a population of 1.2 million people . these are fresh university graduates who have no surgical training or experience . before the placement of volunteers there was no emoc service and those women needing some emergency or operative intervention had the option of returning home or being referred to the regional referral hospital in the town of barhirdar , 120 kilometers away along an unsealed road . there was one hospital ambulance that charged 400 birr ( or about us$30 ) to take them to barhirdar , or an unreliable bus service . the expense of both meant that most women in a critical condition were sent home . the population , knowing that there was very little help to be offered at mota hospital generally did not present to hospital in labor . the hospital had many other problems : no running water , a temperamental generator to cover frequent power shortages , shortage of staff , no blood transfusion service , and a poor supply of drugs to the pharmacy . volunteer teams of one obstetrician and one volunteer midwife were recruited from holland , australia , india , and america . they would stay for periods of 24 months , usually 3 . over the 3 years they were self - funded with respect to air travel , visas , living expenses , and health insurance . accommodation was provided at the hospital , medical registration was organized with the amhara national regional state health bureau , and internal transport was provided by the program . the first volunteer team arrived at mota in may 2010 and the last left in june 2013 . a supervisory visit was made by a volunteer in january 2014 and then in may 2014 . the role of the volunteers was to establish and provide an emergency obstetric service , including full operative and emergency care along with blood transfusion service . they were also to supervise and train local staff . a retrospective analysis of monthly hospital records from january 2009 until april 2013 was done , with 2009 being the control year . since the placement of the volunteer teams of obstetricians and midwives within mota hospital began in may 2010 , the intervention took place during only some months of the year , so this year was excluded from the comparison . data were collected from the birth registry book and entered into a microsoft excel spreadsheet at the end of each month and the raw data analyzed from excel . outcome measures were the number of deliveries before , during , and after the 3-year intervention period , the maternal mortality rate , and maternal morbidity rate , with the latter assessed by the number of referrals of obstetric fistula patients to a nearby specialist fistula repair centre . also analyzed were the instrumental and operative delivery rates , number of women needing referral during labor , and perinatal mortality . the placement of volunteers was phased out when the regional health bureau was able to staff the target hospital sufficiently to provide the service without outside assistance . there was no ethical board at mota hospital at the time of our study , and as this was a review of cases , permission to do the study was granted by the current medical director . there was a 40% increase in the number of women delivering within the hospital from 738 in 2009 to over 1,000 in both 2011 and 2012 ; there was a slight proportional decrease in the number of assisted vaginal deliveries ( table 1 ) . there was an obvious increase in the number of deliveries by cesarean section as there was no service provided in 2009 ( 0.0% ) and the cesarean rate was 8.7% and 10.7% for 2011 and 2012 , respectively . there was a large decrease in the number of patients referred to the referral hospital in barhirdar for further treatment : from 79 ( 9.3% ) pregnant women in 2009 to only one in 2011 and 2012 . this referral was at a time when there was no anesthesia cover for a short period of time and the patient needed an operative delivery . , it is estimated that there were 17 maternal deaths within the hospital itself ( or 2.4% of women delivering ) , but there were at least 100 patients referred to barhirdar or sent home in extremis during 2009 as there was nothing the hospital could offer the patients . many women died en route to barhirdar or after arrival and most women who went home died . estimating that up to 50% of women transferred or sent home died would make approximately 60 maternal deaths that year , or one in 14 women presenting to the hospital ( 738 deliveries plus 100 women turned away ; 60 deaths from 838 women ) . this figure could easily be higher and is thought to be a conservative estimate . compared with 2009 , in 2011 and 2012 there were no women turned away from the hospital and only one transfer with 15 maternal deaths over the 2 years from 2,043 deliveries  this works out to be less than one in every 157 women who presented for delivery at mota . the number of perinatal deaths was not recorded in 2009 , so comparison was not possible . most of these were either stillbirths with the woman presenting late in labor with the fetus already deceased in utero on arrival , or other unavoidable deaths often associated with a long labor , uterine rupture , and sepsis . the number patients with obstetric fistula referred from mota hospital for fistula repair in a specialist unit in barhirdar in 2009 was eleven , as per mota hospital records ( 1.5% of women delivering ) . from ab s experience of working as the surgeon at the barhirdar fistula hospital during those years , on average , four fistula patients would present per month , a total of up to 48 women , most of whom delivered in mota hospital  so the real figure is likely to be higher . after the intervention , over the 2 years , twelve ( 0.5% of hospital deliveries ) presented at mota hospital with an obstetric fistula , none of whom had their fistula develop within the hospital , but already had the injury on arrival in labor . the regional health bureau placed a local health officer with emoc training in mota hospital in january 2013 and the volunteers worked alongside the health officer before leaving . after withdrawing the full time volunteer presence and leaving the service in the hands of the local health officer , monitoring visits were made six and 11 months later . the number of deliveries was maintained at the same level as when the volunteers had left . no maternal deaths and few stillbirths were recorded , although it was unclear if adequate records had been maintained for accurate comparison of the latter two parameters . there have been many different efforts to try to combat maternal morbidity and mortality in the developing world , from introducing  birth preparedness schemes,4 to getting women to assess health facilities during labor,5 and even providing financial assistance and motivation.6,7 the ultimate aim of these interventions has been to get women to deliver within a health institution . however , there has been some question as to whether it is worthwhile encouraging women to access health services if the quality of the health services is poor.8,9 other groups have thus focused on brief periods of intensive training to improve this , but the impact of short - term training has been questioned.10,11 it is certainly our personal experience that short - term training , although enthusiastically taken on board , makes little impact on changing practices on the ground . it appears more long - term investment into training over years is what slowly brings change , which was the aim of the program reported here . as expected , establishment of an emoc service at mota has had positive benefits for the women who are able to attend the hospital for antenatal care and delivery , most particularly in relation to maternal death , which fell from a conservatively estimated 1 in 14 in 2009 to 1 in 157 women delivering within the hospital during 2011 and 2012 . many of the maternal deaths were high - risk patients who had not attended any antenatal services and arrived at the hospital in labour , in extremis from surrounding rural areas . it was interesting to note that a further increase in women coming to the hospital to deliver did not occur in the second year of activity in mota  this has been taken to indicate that even though there are undoubtedly thousands more women in the region who could benefit from delivering in mota , they live too far away to walk there , are too poor to afford public transport , or live too far away from a road . the women who came for delivery at mota were probably only from the immediate surrounds and it is likely the women from more remote areas remained at home to deliver . the benefits the volunteers brought were not only the introduction of a service and training of all staff , including cleaners , but also an improvement in infrastructure . the volunteers certainly felt ownership of the project and raised money from their home countries to fix the water well ; replace water piping ; purchase a new water pump to ensure a water supply to the hospital ; and buy other surgical instruments , supplies , and training equipment . the other impact was on the volunteers themselves , many of whom have returned for their second or third term of volunteering while two others have committed to 12 years of volunteering at other sites having had their the budget for the intervention was low ; initial funds were used to upgrade hospital accommodation for the volunteers and in - country transport to get volunteers to the hospital . the project budget was also used to purchase new delivery equipment and an ultrasound unit , repair a water well , purchase a new pump for the well , and repair plumbing to ensure a water supply to the hospital . although this is a single example of one site in ethiopia , the intervention had a very positive impact on maternal morbidity and mortality . the analysis was limited by rough , incomplete records being interpreted for 2009 and for the period of 2013 after the volunteers left . although the follow - up after the 3-year intervention is only at 11 months at this stage , we have seem a sustainable improvement in services and significant impact on maternal morbidity and mortality for very little overall financial input . we believe it has been a cheap , effective strategy to commence an emoc service in an area that has never had one and we believe it is also sustainable , as the service , now successfully started , has been handed over to the responsible ethiopian health bureau . similar projects utilizing volunteers have been undertaken in four other hospitals in ethiopia and two in tanzania with similar success . placement of volunteer teams of obstetrician and midwife volunteers had a positive and ongoing impact on the women of the area of mota in terms of both maternal morbidity and mortality . it was cheap , is easily replicable , and if volunteers can be found , can easily be introduced into other areas .
