Abstract
Background: The primary bottleneck to achieving the MDGs in low-income countries is health systems that are
too fragile to deliver the volume and quality of services to those in need. Strong and effective health systems are
increasingly considered a prerequisite to reducing the disease burden and to achieving the health MDGs. Zambia is
one of the countries that are lagging behind in achieving millennium development targets. Several barriers have
been identified as hindering the progress towards health related millennium development goals. Designing an
intervention that addresses these barriers was crucial and so the Better Health Outcomes through Mentorship
(BHOMA) project was designed to address the challenges in the Zambia’s MOH using a system wide approach. We
applied systems thinking approach to describe the baseline status of the Six WHO building blocks for health system
strengthening.
Methods: A qualitative study was conducted looking at the status of the Six WHO building blocks for health
systems strengthening in three BHOMA districts. We conducted Focus group discussions with community members
and In-depth Interviews with key informants. Data was analyzed using Nvivo version 9.
Results: The study showed that building block specific weaknesses had cross cutting effect in other health system
building blocks which is an essential element of systems thinking. Challenges noted in service delivery were linked
to human resources, medical supplies, information flow, governance and finance building blocks either directly or
indirectly. Several barriers were identified as hindering access to health services by the local communities. These
included supply side barriers: Shortage of qualified health workers, bad staff attitude, poor relationships between
community and health staff, long waiting time, confidentiality and the gender of health workers. Demand side
barriers: Long distance to health facility, cost of transport and cultural practices. Participating communities seemed
to lack the capacity to hold health workers accountable for the drugs and services.
Conclusion: The study has shown that building block specific weaknesses had cross cutting effect in other health
system building blocks. These linkages emphasised the need to use system wide approaches in assessing the
performance of health system strengthening interventions.

Background
In the year 2000, the United Nations millennium declaration was signed by 189 member countries. These were
later translated into eight millennium development goals
(MDGs) which were to form a basis for development
and poverty eradication throughout the world. Out of
the eight MDGs, three are directly related to improvement of health [1,2].
The drive to produce results for the MDGs has led
many stakeholders to focus on their disease priority first.
However, recent evidence has lead to concerns that
many member countries especially in poorer nations will
be unable to meet the MDG targets by the year 2015
[1,3]. Experience to date, suggests that if health systems
are lacking capabilities in key areas such as the health
workforce, drug supply, health financing, and information systems, they may not be able to respond adequately even if there was an increased in funding and
technical support. Furthermore, there is concern that
already weak systems may be further compromised by
over-concentrating resources in specific programmes,
leaving many other areas further under-resourced [3,4].
It has now been recognised that a primary bottleneck to
achieving the MDGs in low-income countries is health
systems that are too fragile and fragmented to deliver
the volume and quality of services to those in need [3,4].
Strong and effective health systems are increasingly considered a prerequisite to reducing the disease burden
and to achieving the health MDGs, rather than the outcome of increased investments in disease control. As a
consequence, health systems strengthening (HSS) has
risen to the top of the health development agenda.
In order to justify continued investments in health systems, there is need to generate evidence that such investment lead to improvement in health [5]. Hence, the
design and evaluation of health system strengthening interventions need to be rigorous and robust [6]. In this
regard, WHO has proposed a framework of health system building blocks that describes six sub-systems of
overall health system architecture. The building block
approach could help in identifying bottlenecks in the
health system and guide efforts in resource allocation
and performance evaluation [7]. Anticipating how an
intervention might flow through, react with, and impinge on these sub-systems is crucial and forms the opportunity to apply systems thinking in a constructive
way in health system strengthening [8,9].
In recent times, public health researchers and practitioners have been turning to systems thinking to tackle
complex health problems and risk factors. Recent projects have used systems thinking to address specific public health problems like tobacco consumption, obesity
and tuberculosis [10-12]. In its recent report, WHO has
noted that systems thinking has huge and untapped
Page 2 of 9
potential in addressing broader health systems problems
[8]. It has been argued that application of systems thinking
could help in identifying leverage points in a complex
health system and could be valuable in guiding the design
and evaluation of public health interventions [13,14].
Zambia is one of the countries that are lagging behind
in achieving millennium development targets. Several
barriers have been identified as hindering the progress
towards health related millennium development goals.
These include socio-cultural practices, poor referral systems, limited health infrastructure and lack of qualified
health human resources [15]. These barriers limit access
to health services especially in rural areas. Designing an
intervention that addresses these barriers was crucial.
The Better Health Outcomes through Mentoring and
Assessment (BHOMA) project was born with the
current challenges in the Zambia’s MOH in mind and
the need to provide a system wide solution rather than
disease specific. The BHOMA project was designed to
work at district, community and health facility level in
the target districts. The full methodology of the
BHOMA study is described elsewhere [16].In this paper,
we applied systems thinking approach to describe the
baseline status of the six WHO building blocks. The
main objective was to provide a baseline qualitative analysis of the status of the health systems building blocks
before the implementation of the BHOMA intervention
in the target districts. This qualitative paper complements
baseline quantitative results reported elsewhere [17].
Methods
We used qualitative ethnographic methods to analyse the
status of the Six WHO building blocks in three BHOMA
districts using systems thinking approach. The three districts were purposefully sampled to act as pilot districts
for an innovative health system intervention with the aim
of learning and rolling out the intervention to others districts. The other selection criteria were that these must be
rural districts and have similar health system challenges to
other rural districts in Zambia. The study was conducted
between January and March 2011.We conducted key informant interviews and focus group discussions.

A total of three districts and nine health facilities were
included in the study. Three health facilities were selected
in each district. The selection criteria were that in each
district one rural, one semirural and one urban health
facility was to be included. Where there was more than
one eligible health facility one was randomly selected.
At each facility, the health centre in-charge, Chairperson of the Neighbourhood health committee (NHC) and
a pharmacist were interviewed.
Around the catchment area of each health facility, two
Focus Group Discussions (FGDs) were held with men
and women. In total 30 key informant and 18 FGDs
were conducted.
Selection for FGD participants
Community groups were organized with the help of
local leaders and community health representatives who
helped in informing community members about the
dates and time of the interview. Attention was paid to
the group heterogeneous characteristics, i.e. different occupations, social networks, educational status. Men and
women were interviewed separately.
All group discussions were held away from the health
facility to avoid influence from the health workers .All interviews were recorded and later transcribed by trained
research assistants familiar with qualitative methods. The
transcribed material was validated by the team leader.
facility to the community.
Finance: User fees and indirect payments,
Data was collected by the research team comprising
the main researcher and three research assistants trained
in qualitative methods.
Data analysis
Data was transcribed by five research assistants trained
in qualitative methods. All scripts were checked and validated by the main researcher. Transcripts were cleaned
and exported to Nvivo 9 for analysis. Coding was done
by the main researcher and checked by the second researcher experienced with qualitative methods. Data
coding followed pre-determined themes based on health
system building blocks. These formed the basis for
broader themes which were further subcategorised to increase the explanation ability of the data.
Ethical consideration
The study was approved by the University of Zambia
Biomedical Ethics Committee and London School of Hygiene and Tropical Medicine. All participants were informed about the study and signed a consent form before
being enrolled in the study. Confidentiality was maintained
throughout data collection, analysis and publication.
Results
Data collection
Three different interview guides were used for data collection. Two separate key informant interview guides
targeting health workers and community representatives
and one Focus group discussions guide for collecting information from community members were developed.
The themes and questions were based on literature and
reported challenges in the Zambian health system. The
questions were pre-tested in pilot health facilities within
the BHOMA intervention and adapted to reflect the
Zambian health care settings. Focus group discussion
guides were translated into local languages spoken in
study sites. Key informant interviews were conducted in
English except those for community representatives.
Questions covered the six building blocks for health system from both demand and supply side:
Service delivery: Access and barriers to health
services.
Health human resources: Availability, gender and
attitude of health workers.
Health service delivery building block
Barriers to accessing health services
Several barriers were identified as hindering access to
health services by the local communities. These included
supply side barriers: Shortage of qualified health workers,
bad staff attitude, poor relationships between community
and health staff, long waiting time, confidentiality and the
gender of health workers. Demand side barriers: Long
distance to health facility, cost of transport and cultural
practices.
Staffing, attitude and waiting time
The staffing levels at health facilities appeared to have a
bearing on the patient/provider relationship. It appeared
that it was not possible to improve the relationship between the community and the health facility by simply
increasing the number of health workers disregarding
the issues of behaviour and attitude of health workers.
Most members of the community were discouraged
from seeking medical attention if the health workers
were rude and uncaring. Some community members
Mutale et al. BMC Health Services Research 2013, 13:291
http://www.biomedcentral.com/1472-6963/13/291
only came to seek services if the right health workers
were on duty. While most health workers blamed the
bad relationship between the community and health
workers on fewer numbers of health workers, the community members felt that it was not enough to have
more health workers. They insisted that the health
workers must be caring and have a positive attitude towards work. Waiting time before being seen by a health
worker was one indicator of not only the low number of
health workers but also a reflection of bad working practices and attitude by health workers. The long waiting
hours were a recipe for poor relationship and this was
self-reinforcing:
“Staffing should be improved at the clinic. If the clinic
has adequate staff when patients come they will spend
less time at the clinic.”
Male FGD participant, Chongwe
Community attitude
Community members have a duty to help health workers
to perform their duty without risking their lives. Therefore, the issue of improving relationships at health centres has both demand and supply side. Findings from
our study showed that the community does not seem to
see their responsibility to be crucial in improving relationships with health workers. Community members
expected health workers to improve their attitude and
not the community needing to change to accommodate
health workers. Sometimes the community delayed in
seeking medical help until the case was very serious.
This was seen as bad community practice that needed to
change. However, the community blamed the delays on
health workers who they said were unwilling to attend
to none serious cases, so community members had no
choice but to wait until the illness was very serious in
order to draw attention from health workers.
“You see, other people stay far away from the clinic
and have no money for transport.
This makes them to delay in seeking health care until
the illness becomes very serious.”
Male NHC chairman, Luangwa
Inequalities in access to health services
Access to health services is vital for all age groups and
gender. In our study area, services seemed to favour
women and children. Participants reported that men
were usually bottom on the list when it came to receiving help from health services from the health facility.
This was reflected in the following quote:
“In most cases when children have got problems they
are given medication including injections.
Page 4 of 9
Adults are usually told that drugs are out of stock so
they have to buy on their own.”
Male FDG participant, Kafue
Confidentiality
Stigma remained a challenge in accessing HIV and sexually
transmitted diseases services. Many clients feared that
health workers could breach confidentiality if they were
told about such sensitive matters. In contrast, NHC members believed that health workers maintained confidentiality
at all times. One such service negatively affected by stigma
was couple counselling for HIV which has remained low.
“Sometimes patients are not free to talk to health
workers, for example they may have an STD but it may
be difficult for them to explain to the health workers
until the condition becomes very bad. In some cases,
patients have died at home that is when people discover
that they were suffering from this and that disease.”
Male, FDG participant, Luangwa
Distance and transport costs
Long distance from health facilities and cost associated
with transporting patients to local health facilities and referral centres were the major demand side barriers to
accessing health services on time. There was limited access
to ambulance services in most rural health facilities and in
some cases patients referred to hospital were asked to arrange their own transport. This resulted in some referred
patients staying and dying at home because they could not
afford transport costs. In fact services rated very poorly in
most health centres were those needing referral to other
institutions to complete the management of illness.
“Sometimes when the patient is very sick they are
unable to sit on a bicycle and are unable to walk so
you find that it would even take time for them to come
and reach the health services.”
HC, in-charge, Kafue
“For T.B, we still have problems in the sense that for
us to know that a person has T.B, when they get
sputum they have to take it to a bigger hospital for
laboratory testing after testing if they find T.B that is
when they come here to receive T.B drugs.”
HC in-charge, Chongwe
Health human resources building block
Shortage of health human resource
The density of qualified human resources has been
found to be important in improving the quality of health
services. In the absence of trained health workers service
delivery could be severely compromised [18,19]. In our
study we found that there was a general shortage of qua-

http://www.biomedcentral.com/1472-6963/13/291
lified human resources such that patients were sometimes attended to by cleaners and other untrained staff.
“The health workers are not enough sometimes. When
you have a patient you take him to the clinic and if
the nurse is not around, then you are attended to by
the cleaner who is not trained to do that job so we
need more nurses.”
Male FDG participant, Luangwa
Task shifting: are the unpaid daily employees (CDEs) the
answer?
In recent times, there has been an increased emphasis
on task shifting as a solution to the problem of staff
shortages for qualified health workers. This has taken
different forms in many countries with some volunteers
or paid lay workers taking up some roles originally done
by qualified health workers [20-23]. In Zambia, a cadre
known as Classified Daily Employees (CDEs) are helping
health workers to perform some tasks which they have
never been trained to do. Though some of them have
now been put on government payroll, most of them
work on voluntary basis and perform tasks ranging from
patient screening to prescribing and despising drugs.
The findings showed that, although CDEs were seemingly willing to help at the health centre, they appeared
to have deep seated bitterness for not being paid despite
their contribution. Though most of them accepted that
their work was supposed to be voluntary, after working
for some time, they generally felt entitled to remuneration and indirectly showed signs of demanding payments for their work. They contended that they were
overwhelmed with responsibilities and required to work
awkward hours just like trained health workers yet without pay. There was a feeling of abuse and helplessness
among many CDEs.
“According to me we still have so many problems
because even as I am here we are not paid. You see
because of the job I do here, I am unable to do other
jobs which can give me money, but instead I help the
people (staff ) who are paid by the government so that
is a big problem for me.”
Male CDE, Luangwa
Suggested motivation for CDES
Although some CDEs are currently working on voluntary
basis, they were keen to receive incentives as a motivation
as well as a sign that their work was being appreciated.
Though money was seen as important, other forms of motivation highlighted during the study were less complicated than initially thought. These included positive
complements, simple certification, training opportunities
Page 5 of 9
and being given priority when new research projects are
being implemented in the area.
Gender and age of health workers and health facility
delivery
The gender of health workers can positively or negative
affect access to health services. The type of health services likely to be affected may differ by area of residence
and cultural beliefs. In our study male nurses were seen
as a hindrance to health facility deliveries as many women expressed reservations to being attended to by male
nurses during labour. This could be a cultural issue
which is more pronounced in rural areas than urban.
For example in one rural health facility in Kafue district,
there was only a male nurse attending to patients including pregnant women. He acknowledged that some
women were not happy to give birth at the health centre
because it was manned by a male health worker and so
they preferred to give birth at home or other facilities
were female workers were present. This finding was confirmed through interviews with women and men in the
community.
“You know we only have a male nurse here, we need a
female nurse. Because of this problem other women
give birth from home or go to nearby hospital.”
Female FDG participant, Chongwe
Younger health workers discouraged older clients from
seeking health care as explained by one respondent:
“Some people fail to come to the clinic because of the
age of the health workers for instance some are young
as a result those who are older than them fail to come
to the clinic.”
Male FDG participant, Chongwe
Medical and drug supplies building block
Managers’ and community perception of drug availability
The health facility in-charges’ perception of drug availability was interestingly different from the community
members who felt that the drugs were not always available. Most health facilities experienced shortages of essential drugs. This was attributed to irregular supplies of
drugs by the government.
Interestingly, whether drugs were in stock or not revealed important insights that must be considered when
planning for drugs and other medical supplies.
Some drugs were in stock because there were few
cases to be treated not because there was a good supply.
Other drugs run out because there was higher demand
compared to supply. Some health facilities had high
population but the drug supplied seemed to be fixed.
Mutale et al. BMC Health Services Research 2013, 13:291
http://www.biomedcentral.com/1472-6963/13/291
This was reported in bigger health facilities located in
peri urban areas as expressed by one respondent:
“The population is big and the drugs the government
send us are not enough.”
Female FDG participant, Chongwe
Some drugs run out of stock because they were more
used than others. In some cases community demanded
to be given certain drugs as they felt these were most
helpful. For example, there seemed to be a belief among
most community members that flagyl (an antibiotic) was
good medicine for diarrheoa and if not given some
members of the community felt betrayed. In such instances, some health workers felt obliged to give such
medication even when they knew that would not change
the course of the illness. This was done for the sake of
maintaining confidence and trust in the health services
being provided at health facility.
When some medicines run of stock, patients were given
prescriptions to buy from private pharmacies. Most clients
were not happy to be given prescriptions as they had no
money to buy drugs from private pharmacies.
“Sometimes when you go to the clinic they just give you
a prescription for you to go and buy medicine.If we
can’t afford to buy books, how can we afford to buy
medicines from private pharmacies?”
Female FDG participant, Luangwa
Governance at health facility level
Health system governance has many facets. Some elements of governance include transparency, accountability
and community participation [24]. We collected information about some elements of governance from both facility
managers and community perspectives.
Community participation in health services
There were gender differences in community participation in health service provision. Male community members were more likely to participate in health facility
initiatives and were well informed about services available at the health facilities and took part in the activities
of the health facility. In contrast, most female participants were not aware of the activities that were going on
at the clinic. However, when asked about who owned
the health services at health facility, most respondents
including women said that the health services were
owned by the community despite their low participation.
Page 6 of 9
health workers accountable vary from community to
community and area of residence (rural vs. urban) [25].
In Zambia the Ministry of health has recommended formation of neighbourhood health committees as part of
the governance structure for a health facility. These are
expected to act as representatives and eyes for the community [26]. We explored the extent to which the communities or their representatives held the health workers
accountable for resources especially drugs.
The results showed that, community members including members of NHC assumed that the nurses and clinical officers accounted for the drugs and did not actively
ensure that this was done and appeared quite ignorant
of the process of accounting for the available drugs and
medicines.
The community seemed to be incapable of holding
health workers accountable for the drugs and services as
in most cases they didn’t know how the health workers
did their work and so could not ask intelligent questions
as highlighted by one NHC committee member:
“The workers at the clinic are the ones who see to it
that the medicines are given to every patient us from
the community we don’t know.”
NHC chairman, Luangwa
Finance building block: indirect payments
The Zambian government has abolished user fees in
rural areas to protect patients and their families from
catastrophic health expenditures [27]. This policy has
been adopted and is said to be working in most health
centres throughout Zambia. In this study we wanted to
confirm whether health facilities were indeed not charging patients for services received. The result showed
that although most of the selected health facilities indicated that they did not charge user fees to patients or
clients, in reality there seemed to be indirect payments
through forcing clients to buy books from health facilities or shops. Those without books were not being
attended to by health workers at health facilities. This
was seen as a form of payment by most community
members who felt discouraged from seeking medical attention even when they were very sick because they
could not afford to by a note book. One respondent
said:
“We don’t pay user fees, it is for free. But we are told
to buy books from the clinic once we buy from
somewhere else they refuse to write in them.”
Female FDG participant, Chongwe
Accountability for the resources
It is crucial that members of the community provide
checks to health workers to ensure equitable access to
health service. The capacity for community to hold
User fees were officially requested for patients crossing
from Mozambique into Zambia seeking medical attention in Luangwa district. This was not the case in
Mutale et al. BMC Health Services Research 2013, 13:291
http://www.biomedcentral.com/1472-6963/13/291
Chiawa (Kafue) were Zimbabweans seeking health services in Zambia did not pay any form of user fees.
Health information
Information flow from the health centre to the community about new services was very inconsistent and
appeared to depend on community volunteers. While
most health workers assumed that the NHC communicated information to the community, there was no way
of verifying this. Most community members denied being aware of new services or initiatives that were being
implemented by the health facility. Interesting health information flow appeared to favour males who acquired
information through their local social networks more
than female respondents.
“The villagers do not know or are not aware of all the
programmes offered by the clinic as some of them in
most cases have to ask if certain services are offered by
the clinic.”
Female CDE, Luangwa
Discussion
The study has shown that building block specific weaknesses had cross cutting effect in other health system
building blocks which is an essential element of systems
thinking [28]. These linkages emphasis the need to use
system wide approaches in assessing the performance of
health system interventions [8]. It was clear that challenges noted in service delivery were linked to human resources, medical supplies, information flow, governance
and finance building blocks either directly or indirectly.
Service delivery was directly affected by availability of
trained health workers. In addition, the attitude and gender of health workers were other key human resource attributes that affected access to health services.
While the concentration of health workers was important, their behaviour and attitude toward patients
was even more important to the community. Bad health
worker attitude discouraged some people from going to
health facility and was cited as a reason for long waiting
time at health centres rather than the lack of human resources. Other studies have reported similar concerns
about the attitude of health workers and how it has an
influence on service utilisation [29].
The gender of health workers was an important consideration when it came to health facility deliveries. Most
female participants were reluctant to deliver at the
health centre if the only health worker available was
male. In such cases, clients preferred to deliver at home
or being assisted by traditional birth attendant. The refusal by most women and their partners to be attended
to by a male health worker during labour was common
in rural health facilities where it was seen to be cultu-
Page 7 of 9
rally inappropriate to be attended by the opposite sex
during labour. This finding has implication when it
comes to attainment of millennium development goals
on maternal and child health [1,30].
Another factor noted as a hindrance to accessing HIV
and STI services was perceived lack of confidentiality on
the part of health workers. Most community members
feared that health workers would leak information about
their HIV or STI status if they went to the nearby health
facility. This resulted in delays in seeking medical attention with associated complications. The fear of breaching confidentiality has been reported in Zambia even
among health workers when they come to seek HIV services [31]. It is important that health workers are trusted
by community to keep confidential information. If patients are assured of confidentiality, they are more likely
to seek medical attention early at the nearest health
centre [32].
In few places, there were no qualified health workers
and such health facilities were being manned by unqualified personnel known as Classified Daily Employees
(CDEs). Similar findings have been reported in other districts within Zambia [33]. These usually worked on voluntary basis. The study findings showed that they had
no formal training or evaluation. With most health facilities having only one trained health worker, in the absence of trained health, the responsibility fell on CDEs.
This puts the patient’s lives at risk and severely compromised quality of service delivery [22]. While most of
them were doing their best to help on voluntary basis,
the indications were that this was not sustainable. Most
CDE wanted to be trained and to receive allowances and
other incentives which were not currently available.
While task shifing has been noted to be successful elsewhere, its success has depended on training of lay
workers to do specific tasks and not necessarily managing patients on their own as this responsibility falls on
qualified health workers [20,34,35].
There was a general feeling by the community that essential medical supplies were usually out of stock. Rapid
diagnostic tests for malaria (RDT) and antibiotics were
said to be out of stock most of the time. This had negatively affected trust in the health system as most participants felt cheated when they were only given prescription
to buy medications which were not in stock. The reason
for stock out was that supply of medicines was fixed while
the demand had kept increasing. It was not possible to
know whether health workers misused the medical supplies as the community and its representatives lacked capacity to hold health workers accountable for medical
supplies. They simply trusted that health workers were
doing a good job.
Access to health services had been declared free in Zambia
following removal user fees [27]. This was reported to be
Mutale et al. BMC Health Services Research 2013, 13:291
http://www.biomedcentral.com/1472-6963/13/291
the case in all health centres except a few places in
Luangwa where user fees were charged to foreigners seeking health care in Zambia. Nonetheless, there was a requirement that patient provided their own note book for
medical notes. This condition was seen by many as a form
of payment and was discouraging some people from seeking medical attention.
Another barrier to accessing health services was long
distance to health facilities which translated into high
transport for patients and their families [36]. The lack of
ambulance compounded the problem as most clients
were required to facilitate and pay for their own transport and lodging to referral centres. It was therefore not
surprising to find that most services needing referral
were among the worst performing.
Conclusion
In summary, there were close linkages between service
delivery and other health systems building blocks. Challenges affecting particular building blocks seemed to
have ramification in other building blocks directly or indirectly. For example, the attitude, behaviour, gender
and age of health workers seemed to have an effect on
trust and demand for health services. It is therefore essential to apply system wide approaches when evaluating
health systems due to close linkages that exist between
sub-systems. It was clear that the success or failure
reported in one building block accounted for success or
failure reported in other building blocks.
