Pregnancy Clinical Trial
Official title:
IMPACT OF HOME BASED LIFE SAVING SKILLS TRAINING IN A RURAL AREA IN TANZANIA IN FACILITY DELIVERY, PREPARATION OF BIRTH PLANS AND COST-EFFECTIVENESS. AN INTERVENTION CLUSTER RANDOMIZED TRIAL.
Background
The maternal mortality ratio in Tanzania has been persistently high for ten years with no
signs of the ratio going down.The Tanzania Demographic and Health Survey (TDHS) of 1999 and
2005 estimate the maternal mortality ratio to be 528 and 578 per 100,000 live births
respectively (TDHS 1999, TDHS 2004/05).The major direct causes include obstetric
haemorrhage, obstructed labour, pregnancy induced hypertension, sepsis and abortion
complications.
Most deliveries (53%) in Tanzania occur outside the health facilities. Of these 53% of
births that occur outside the health facilities 31% are attended by relatives, 19% by
traditional births attendants (TBA) while 3% have no assistance at all. Though, the
proportional of mothers delivering in health facilities (47%) and receiving skilled
attendance at birth (46%) is low but more than 94 percent of women attend antenatal care
(ANC) in health facilities at least once. This indicates that there are factors that impede
these women delivering in the health facilities.
Low awareness of obstetric danger signs may be one of the contributing factors for delay to
decide to seek care when a complication occur thus contributing the first phase of delay.
Studies in Tanzania show that most women are not aware of danger signs of obstetric
complications during pregnancy, delivery and after delivery. A study conducted in Mtwara
rural to assess the use and determinants of skilled attendants at delivery showed that
proportional of women delivered with skilled care increases with increasing knowledge of
pregnancy danger signs, but it also showed that few women have knowledge of pregnancy danger
signs
An increasing body of evidence supports the importance of community participation in
maternal and infant health programs for establishing ownership, identifying problems
effectively, achieving equity and helping to institutionalize health programs. To mount an
effective maternal health effort aimed at reducing maternal and infant mortality, multiple
levels of program and policies need to be in place and functioning. In addition, linkages,
from the communities, local dispensaries and health centres to first referral hospitals that
are adequately equipped, need to be developed and sustained
A home based life saving skills (HBLSS) is a strategy that intends to educate pregnant women
and their primary family caregivers and home birth attendants on critical knowledge and
skills to keep a pregnant woman healthy, to recognize life-threatening maternal and newborn
complications and promote the adoption of health care and health-seeking behaviours at the
individual and community levels. The aim of this strategy is to prevent maternal and
neonatal morbidity and mortality through creating awareness on women's birth preparedness
and access to emergency obstetric care services
RESEARCH QUESTIONS
1. Can HBLSS increase women empowerment and male involvement in the decisions relating to
access of emergency obstetric and newborn cares?
2. Can the HBLSS increase hospital deliveries, increase awareness of obstetric and
neonatal danger signs, birth preparedness and emergency readiness in a rural community?
Objectives
Broad Objectives:
1. To investigate social-cultural, community and traditional practices that impact on
women's birth preparedness and access and utilization of emergency obstetric care
services in rural district.
2. To assess the impact of home based life saving skills (HBLSS) on hospital delivery
awareness of obstetric and neonatal danger signs, birth preparedness
Specific Objectives
1. To explore customs, taboos and practices including herbal remedies during pregnancy and
labour that influence birth preparedness and utilization of emergency obstetric care
services.
2. To assess perception, attitude and health seeking behaviour when a complication occur.
3. To determine the effect of HBLSS educational programme on hospital delivery, birth
preparedness, emergency readiness and utilization of emergency obstetric care services
among women in Rufiji district.
4. To assess the impact of HBLSS educational programme on male awareness and involvement
in assisting women on birth preparedness and access to emergency obstetric care
services.
5. To determine the cost-effectiveness of HBLSS educational programme
Methodology
A Cluster Randomized Trial
28 clusters will be randomly selected, 14 clusters will receive HBLSS training and the other
14 clusters will not receive HBLSS training.
STATEMENT OF THE PROBLEM AND RATIONALE
Despite several interventions to address the unacceptably high rates of maternal and
neonatal mortality, the problem still persists. Maternal Mortality ratio in Tanzania has
been persistently high without signs of declining. Currently it stands between 578 and 950
per 100,000 live births (TDHS 2005, WHO 2007). The neonatal mortality rate as well in the
country is 32 per 1,000 live births (TDHS 2005).
Almost 94% of pregnant women attend antenatal care in health facilities at least once, but
only 47% deliver in these facilities and skilled attendance at birth is 46% (TDHS 2005,
Mpembeni et al 2007). Births that occur outside the health facilities are assisted by
relatives, TBA and some women do not have assistance at all (Kayombo 1995, Kayombo 2008,
Comonsky 1983 ). Studies in Tanzania have shown that home birth with unskilled attendants is
often the norm (TDHS 1999, TDHS 2005, Mpembeni 2007). This indicates that there are factors
that impede these women delivering in the health facilities. Among the factors may include
socio-cultural, economic activities, family, community factors. If these factors are
compounded by low awareness of danger signs of obstetric complication then these women and
neonates are more at risk of death when a complication occurs.
Previous studies in Rufiji district showed that community has low acceptance of facility
delivery and referral to hospitals when advised (Pembe 2008b). Furthermore, like in other
parts of Tanzania women have low knowledge of danger signs of complications during
pregnancy, delivery and after delivery despite attending antenatal care (Mpembeni 2007,
Pembe 2008a). In another study on the use of essential obstetric care facilities, a quarter
(60/232) of women with complications were referred to the hospital level but less than half
(48%) arrived at their referral points. Out of 60 referred cases 31 (52%) did not arrive in
any of the two hospitals of the district. Nineteen were traced for their outcome and it was
found that three died on the way to the hospital (Urassa 2005). Consequently, there is a
great need for an innovative and empowering community-based intervention whose
characteristics address this problem.
METHODOLOGY
DESIGN
This will be a cluster randomized trial. The cluster has been chosen because the
intervention is done in the community in groups rather than individuals. The unit of
randomization will be the health care facility. Randomly selected facility clusters will
receive HBLSS in addition to the antenatal care received and the in the control group only
routine ANC will be done.
Study area
This study will be conducted in Rufiji district. Rufiji district is one of the six districts
of the Coastal Region in Tanzania. It is situated about 300 km in Southern of the capital
city Dar es Salaam. The district is more rural with few suburban areas. The district has an
estimated population of 203,102 according to census results 2002 with a male population
being 98,398 and female 104,704 (BoS 2002). Geographically the Rufiji river divides the
district into two halves Northern and Southern parts with the formation of flood plain,
coastal-delta, and plateau zones. Since inauguration of the "Mkapa" bridge in 2003 across
the Rufiji river, transport between northern and the southern part of the district as well
as to the southern regions has improved.
Only the main road from Dar es Salaam to the Southern regions is passable in all seasons,
while other roads in the district are difficult to pass especially during the rainy season.
The limited transport system makes people dependent more on the health services available
within the district.
According to the administrative structure in Tanzania, the district is divided into five
divisions, which are further divided into 19 wards. There are eight wards in the flood
plain, four in the coastal-delta, and seven in the plateau zone. There are 128 villages in
the district. Each village has 2 to 4 hamlets (Vitongoji) under the leadership of a hamlet
chairperson. The average population in a village is 1600, therefore with an annual
population growth rate of 4% it is estimated that 64 women will become pregnant in a year.
The district has two hospitals, Utete a government district hospital and Mchukwi a private
not for profit hospital owned by the Pentecostal church. Both hospitals have doctors, nurses
and midwives providing medical care and surgical care including comprehensive emergency
obstetric care. There are four rural health centres (RHCs) and 52 dispensaries two of which
are private not for profit and another two are private for profit. Antenatal care (ANC) is
provided in hospitals, all RHCs and all dispensaries. The normal practice is for the
pregnant woman to register for antenatal care at the nearest health facility. Dispensaries
and RHCs have guidelines for referring women with risks or complications to hospitals.
Participants Randomly selected facility clusters will receive HBLSS in addition to the
antenatal care received or only routine antenatal care.
The unit of randomization is health facility. 28 health facilities will be selected and
randomised into two groups each with 14 facilities. One group will be provided with HBLSS
educational programme through their VHW while another group will be monitored for the
purpose of comparison
Key participants will be pregnant women together with their immediate relatives such as aunt
and the husband. They will receive the HBLSS training. Village health workers who will be
trained by HBLSS trainers, will be used to provide the training in the community
Intervention The selected clusters will receive HBLSS training. This training is being
conducted in some other parts of Tanzania.
The HBLSS procedure
The HBLSS was conceived as a component of the Community Partnership for Safe Motherhood
Model. It targets a homebirth team consisting of all of those who can be expected to be
present at a birth, namely, the pregnant woman, her family caregivers, and the birth
attendant. The education, motivation, cohesion and mobilization of pregnant women, families
and communities are seen necessary to improve pregnancy outcomes.
HBLSS training was designed by the American College of Nurse-midwives has been successfully
implemented in other developing countries including India and Ethiopia (Sibley et al 2001).
In Tanzania it was adopted and adapted for use and was launched by Honourable Mohamed Shein
the Vice President of the United Republic of Tanzania on the 25th of March 2007 in Morogoro.
The White Ribbon Alliance (WRA) adapted the HBLLS training curriculum taking into
consideration the major causes of maternal mortality in the region and the Tanzanian
context, and translated it into Swahili. The training and materials have been field tested
and the first Training of trainers (TOTs) and the training of community was done in Manyara
region. Other trainings are ongoing. Recently WRA conducted training in Rukwa rural district
that involved district health providers, 20 primary health care providers and 500 community
members from 20 villages. HIV awareness and prevention of mother-to-child HIV transmission
are integrated into the training manual. The strategy is to build on existing practices and
to negotiate acceptable and feasible safe practices with the homebirth team members to
develop both a consensus on the appropriate action and a capacity to take that action when
needed.
The HBLSS training manual has a flexible, modular design comprised of 12 preventive and life
saving skill topics. Drawing on best practices and current research, to maximize effective
communication and learning among community members who may be unable to read, essential
content is reinforced through pictorial Take Action Cards that are taken home for reference.
The trainer uses various teaching methods to maximize effective communication and learning
among participants including:
- Stories and case histories
- Discussion and demonstrations
- Identification of complications using picture cards
- Take Action Cards.
- There will be one Take Action Card for each topic or problem. These cards will be used
during training and a booklet made of these cards will be left at woman's home.
HBLSS sensitization and training
The HBLSS training in the district will start with ten (10) TOTs training at the district
level. These will train the research assistants (RAs) preferably community health worker
(VHW) or health assistants, one from each selected village. The RAs will train the community
on HBLSS. All pregnant mothers will be identified by the RA. The RA will make appointment to
the family according to their convenience. The RA will visit the family every month to
discuss the danger signs, decision making, and birth preparedness and emergency readiness
with the family. The RA will keep all the records of training each family, the number visits
made and whether the woman attended antenatal care or develop any complication. When the
woman delivers the RA will record the place of delivery and whether there was any referral
given.
Sample size: Baseline study
Since the study will employ cluster-sampling, technique, a design effect was taken into
consideration when calculating the sample size. We used a design effect of 2 a value which
have been reported in the most recent Demographic and Health Surveys as a design effect of
the variable "Mothers received medical assistance at delivery" in the Coastal Zone where
this study will be conducted.
Therefore using the above formula and taking into consideration the design effect, a minimum
of 766 women is required for the baseline survey.
Sample size for Cluster Randomized control trial
The sample size for the intervention study which is a cluster randomized trial was
calculated using the Acluster programme methods described by Donner and Klar, 2000. We
estimated the mean cluster size of 100 pregnant women, an intracluster correlation
coefficient of 0.05. We further assume that a power of 90% to detect an increase of 15% in
the rate of hospital delivery. In this case we will need 28 clusters, 14 for intervention
group and 14 as control. We will need to have 1347 women in intervention group and 1347 in
the control group. A 20% in increase will be done so as to offset the loss of follow-up.
Sequence generation
This will be done by including all women who book for antenatal care during the time of the
study, both in the control and intervention clusters.
Allocation concealment
Four health centers will be chosen randomly for intervention and control (2 each). Then
random selection of 24 dispensaries will be done by using random number tables. Allocation
to intervention and control will be done randomly by lottery method.
Statistical methods
Analysis will be done taking consideration on clustering. Primary analysis will be
undertaken as intention to treat at cluster level and individual level. Pearson Chi-square
test will used to compare variables. The result will be deemed significant if p value <
0.05. Multiple logistical regression methods will also be used to see the predictor
variables on the use of health facility for delivery. This will be done for both cluster and
at individual level.
DATA COLLECTION
Baseline information
The provision of emergency obstetric care services using United Nations (UN) signal
functions and Safe motherhood Initiative (SMI) assessment tool in all the facilities will be
done. Health workers will be interviewed to determine their capabilities to undertake
emergency obstetric care in their facilities. Birth preparedness, emergency readiness
including awareness of danger signs of obstetric and neonatal complications among women,
their spouses, head of the households and other family members will be done. Information on
male involvement will also be sought. A structured questionnaire will be used to gather the
information. Information relating to traditionally preferred and/or recommended discouraged
foods during pregnancy will also be collected. In addition, information on other traditional
practices including rituals for the first or the last born child and or twins will be
documented.
Qualitative interviews including focus group discussions (FGDs) and in-depth interviews will
be conducted. FGDs will be done in the community on perceptions, attitudes, male involvement
and health seeking behaviour on the use of emergency obstetric care services. In-depth
interview will be conducted with key informants such as religious leaders and other opinion
people in the community to compliment the data on perceptions of place of delivery and of
obstetric and neonatal danger signs. In-depth interviews will also be conducted to health
care providers to supplements the documentation with focus on factors which make many women
deliver outside health facilities and efforts made to make them deliver in health
facilities. In addition review reports of ward health committee to see if maternal and
newborn features out in the report as a sign of awareness.
Information on traditional pregnancy management practices, including use of herbal plants
and their preparation in facilitating child delivery and their perceived safety will be
collected. Plants used will be collected and botanic identification will be done by a
botanist for scientific names and for literature review for their safety. In addition where
possible concoctions used for facilitating child delivery and for managing pregnancy and
infant health problems will be collected for laboratory screening.
Information from the qualitative studies will also help in preparing instruments for
quantitative studies.
Topic guides will be used during the FGDs and in-depth interviews. We will also conduct an
economic valuation of the training so as to obtain a cost-effectiveness analysis of this
type of educational program.
DATA PROCESSING AND ANALYSIS
Quantitative data:
When data collection will be completed, serial numbers will be assigned to the
questionnaires to facilitate identification of the different patient data. Thereafter
responses for the open-ended questions will be reviewed, categorized and coded for the
computer data entry. Data entry into the computer will be done by the principal investigator
with the help of an assistant using the statistical package for social sciences (SPSS) and
EPI INFO6 computer programmes. Data cleaning will be done. Chi- squared test will be used to
determine association between variables. Where the chi-square test will not be valid the
Yates corrected Chi square test will be used. The results will be deemed significant if
p-value will be less than 0.05.
Qualitative data:
The audio-taped information will be transcribed and then back translated from Swahili to
English to Swahili. A qualitative content analysis method as described by Graneheim and
Lundman will be used for analysis (Graneheim 2004). All texts will be read several times to
identify meaning units, that is, statements that relate to the topic of analysis. The
meaning units will then be condensed. The condensed meaning units will be coded then the
codes will be categorized according to similarities and differences in content.
