abstract
Background: The declining trend of malaria and the recent prioritization of containment of antimicrobial
resistance have created a momentum to implement clinical bacteriology in low-resource settings. Suc-
cessful implementation relies on guidance by a quality management system (QMS). Over the past decade
international initiatives were launched towards implementation of QMS in HIV/AIDS, tuberculosis and
malaria.
Aims: To describe the progress towards accreditation of medical laboratories and to identify the chal-
lenges and best practices for implementation of QMS in clinical bacteriology in low-resource settings.
Sources: Published literature, online reports and websites related to the implementation of laboratory
QMS, accreditation of medical laboratories and initiatives for containment of antimicrobial resistance.
Content: Apart from the limitations of infrastructure, equipment, consumables and staff, QMS are
challenged with the complexity of clinical bacteriology and the healthcare context in low-resource
settings (small-scale laboratories, attitudes and perception of staff, absence of laboratory information
systems). Likewise, most international initiatives addressing laboratory health strengthening have
focused on public health and outbreak management rather than on hospital based patient care. Best
practices to implement quality-assured clinical bacteriology in low-resource settings include alignment
with national regulations and public health reference laboratories, participating in external quality
assurance programmes, support from the hospital's management, starting with attainable projects,
conducting error review and daily bench-side supervision, looking for locally adapted solutions, stim-
ulating ownership and extending existing training programmes to clinical bacteriology.
Implications: The implementation of QMS in clinical bacteriology in hospital settings will ultimately
boost a culture of quality to all sectors of healthcare in low-resource settings. B. Barb

Introduction
The relevance of clinical bacteriology laboratories in low-
resource settings is increasingly recognized in light of the reduc-
tion of malaria burden [1,2] and the crisis of antimicrobial
resistance (AMR) [3,4]. In contrast to HIV/AIDS, tuberculosis (TB)
and malaria, clinical bacteriology does not benefit from disease-
specific control programmes and advances towards implementing
quality systems are conspicuously few. This review describes the
current state of laboratory quality management in clinical bacte-
riology in sub-Saharan Africa and reflects on the challenges and
best practices for moving forward. The target setting is a referral
hospital in sub-Saharan Africa with a ‘moderate infrastructure’(i.e.
including a basically equipped laboratory) [5], where clinical
bacteriology (culture-based detection, identification and antibiotic
susceptibility testing of bacterial pathogens) is either available or
planned. Although this review focuses on sub-Saharan Africa, the
recommendations and best practices are applicable to the general
context of low-resource settings.

Quality, Quality Management Systems (QMS) and
accreditation
Quality in medical laboratories can be defined as accuracy, reli-
ability and timeliness of reported results [6] and a QMS describes the
approach to meet the quality objectives [7]. QMS for medical labo-
ratories are described in international standards [8]. Among them,
International Organization for Standardization (ISO) 15189 [9] and
Clinical and Laboratory Standards Institute (CLSI) QMS01-A4 [7] are
the most widely used and are comparable. They bothcover the three
laboratory phases: (a) preexamination (indication and test selection,
sample collection, transport, reception and accessioning), (b) ex-
amination (analysis and quality control) and (c) postexamination
(interpretation, reporting, record keeping and notification). In
addition CLSI QMS01-A4 introduced 12 Quality System Essentials
(Fig. 1). Accreditation is the procedure to formal recognition that a
medical laboratory is competent to carry out specific tasks [6].Na-
tional regulations either formulate own standards for accreditation
or refer to existing QMS standards. For example, ISO 15189 is the
standard for accreditation of medical laboratories in Europe.
Progress towards accreditation of medical laboratories in
Sub-Saharan Africa
A decade ago an assessment of medical laboratories in sub-
Saharan Africa portrayed a failing system with unreliable analyses
leading to compromised patient care, unnecessary expenditures
and distrust from clinicians and health authorities. The dysfunc-
tional system was declared a ‘barrier to healthcare in Africa’[10,11].
There were urgent calls to do better.
Starting with the Maputo declaration in 2008, successive
landmark events induced global efforts to strengthen national
laboratory health systems in low-resource settings (Tab le 1 ). Ini-
tiatives from HIV/AIDS and TB control programmes extended to
strengthen the general health laboratory system [13,14,15,16].An
unprecedented increase in international funding supported these
efforts [12e14,17e19]. Accreditation according to ISO 15189 qual-
ity standards was pledged [15]. In 2009 the World Health Orga-
nization regional office for Africa (WHO AFRO) launched the
Stepwise Laboratory Quality Improvement Towards Accreditation
(SLIPTA) programme, which prepares clinical laboratories for ISO
15189 accreditation (Annual ASLM Newsletter 2016) [20].In
addition, WHO-AFRO developed the Strengthening Laboratory
Management Toward Accreditation (SLMTA) toolkit to support
implementation of SLIPTA [20] (https://www.slmta.org/toolkit/
english). In 2011 the African Society of Laboratory Medicine
(ASLM) was created to advocate for the critical role and needs of
laboratory medicine and networks throughout Africa [13].Bythe
end of 2016, SLMTA had been implemented by 1103 laboratories in
47 countries worldwide, with Kenya, Ethiopia and Uganda as top
three countries (Annual ASLM Newsletter 2016). Of those, 23 Af-
rican laborator ies currently achieved accred itation to international
standards (K. Yao, personal communication, February 22, 2017). In
addition, the total number of medical laboratories accredited to
international standards in sub-Saharan Africa has increased from
380 in 12 countries by May 2013 [21] to 485 in 18 countries by
April 2017 (T. Mekonen, personal communication, April 24, 2017)
(Fig. 2).
Despite these efforts, the 2014e2015 West African Ebola
outbreak highlighted the role of weak diagnostic infrastructure in
the affected countries. As a response, the Global Health Security
Agenda (GHSA) was launched to promote global health security as
an international priority [22].

limited results. Though there has been some success at integration
of HIV with TB services, other examples are few [19]. The encour-
aging data on the uptake of SLMTA belie the fact that the vast
majority of accredited laboratories are HIV and TB reference labo-
ratories [16,20] with few (4/23, 17%) accredited SLMTA laboratories
in sub-Saharan Africa performing clinical bacteriology. Moreover,
most external quality assurance (EQA) programmes centre on HIV,
TB and malaria [23e28].
Antimicrobial resistance enters the scene, but tools are lacking and
performance is poor
Although the critical need for diagnosis of bacterial in-
fections is long established [10], clinical bacteriology has only
recently achieved prominence with policymakers, prompted by
the increasing recognition of the looming crisis of AMR
(Table 2). In October 2015, the Freetown declaration launched a
framework to establish functional tiered public health labora-
tory networks to AMR surveillance in Africa [22,58]. In addition,
the United Nations General Assembly recently launched several
internationally coordinated actions on AMR. Of note, most of
these initiatives focus on public health implicationsdparticu-
larly outbreak management (in line with the International
Health Regulations [29]) rather than on individual patient care.
The predicted impact of the AMR crisis casts a new urgency on
the need to improve performance levels. In 2012 a publication of an
EQA session among reference laboratories in sub-Saharan Africa
revealed serious shortcomings in bacterial identification and anti-
microbial susceptibility [30]. Adding to the difficulty is the lack of
appropriate tools for training and implementation of QMS in clin-
ical bacteriology. For instance, the SLMTA toolkit includes only few
examples about clinical bacteriology.

Clinical bacteriology and QMS: a difficult fit
Clinical bacteriology deals with multiple specimens, indications
and requirements for sampling and transport. Culture-based bacte-
riology requires skilled operators, is difficult to automate and leaves
much to the individual laboratorian's discretion. In the post-
examinationphase, there are issues of interpretation (contaminating
or colonizing flora) and reporting (e.g. preliminary results of Gram
stain, cultures in progress) and application of expert rules [31e33].
Clinical bacteriology is therefore less amenable to QMS than other
laboratory disciplines, which have single targets and generate
automated quantitative results that allow for statistical monitoring.
Particular challenges in sub-Saharan Africa
Adapting QMS to local realities proves difficult in sub-Saharan
Africa [34]. Besides the well-known limitations of infrastructure,
equipment, consumables and staff, additional issues merit
comment. Most laboratories in sub-Saharan African hospitals are
small [34] and provide haematology, clinical chemistry, parasi-
tology and sometimes blood transfusion services on a 24/7 basis.
Staff not familiar with QMS may associate quality with goodness
rather than with conformance to requirement [6]. In view of the
small scale and daily burdens, quality essentials such as assess-
ments, customer focus and process management may be perceived
as superfluous, and the concept of prospective risk management
may be too unfamiliar [34]. Further, the digitalization of laboratory
and hospital information, automation and bar code trackingd-
which have dramatically reduced errors at all examination phases
[6,35]dare not yet implemented in sub-Saharan laboratories and
the requirement to validate and secure laboratory information
software (LIS) tools is difficult to meet [34]. An additional challenge
in many low-resource settings is the lack of unique identifiers for
patients with naming practices leading to many people with the
same name or names that change over time, lack of identity cards
and exact birth dates.

Implementing QMS in clinical bacteriology in low-resource
settings: best practices
Implementation of a QMS comprises all 12 Quality System Es-
sentials, but approaches and priorities may vary according to the
local situation [6]. Below, we present some best practices about
how to implement QMS in clinical bacteriology on site. They are
compiled from existing literature (though mainly conducted in
high-resource settings) complemented with our own experience.
Connect to national regulations and public health laboratories
Alignment with national regulations is imperative and will
guide towards legal requirements such as participation in EQA
programmes [36]. Much can be adopted from the expertise of the
disease-specific control programmes of malaria, HIV/AIDS and TB
and their respective reference laboratories: they provide logistic
support (equipment and quality-assured consumables and stains)
and dedicated procedures, job descriptions, forms and logbooks in
local languages [37]. In addition, they organize trainings, external
quality controls, on-site supervision visits and meetings with the
laboratory heads. They further offer advanced techniques, coordi-
nate surveillance activities and create national laboratory networks
for diffusing of knowledge and competencies [22,38].
Participate in EQA programmes
EQA programmes improve laboratory performance (provided
implementation of corrective actions in case of failures) and are
cost-effective [30,39]. They allow the participants to benchmark
and monitor their competence and to verify their methods; in
addition, they provide didactic and educational stimulus [6,40].
Beyond that, EQA programmes provide health authorities with
information about overall competence of laboratories, in vitro di-
agnostics' performance and training needs [6,28,39,41]. EQA pro-
grammes further generate excellent opportunities to integrate
vertical disease control programmes, for instance by sharing dis-
tribution canals and increasing nationwide coverage [28,39]. Short
turnaround times, swift communication (e.g. sending correct an-
swers directly after closure), well-structured didactic reports
anddin our experiencedpersonalized feedback and EQA-oriented
trainings are instrumental to a productive EQA session [39].
Observe and understand the local scene, find support and allies
Support from the healthcare facility management at all levels is
essential to success, as is a well-functioning relationship between
clinicians and laboratory staff. A strategy that has proved powerful
in antibiotic stewardship activities is the ‘engagement of peer

champion advocates’[42], which means engaging individual lab-
oratorians, clinicians and administrators to promote a culture of
quality. Clinicians can play a role at the pre- and postanalytical
processes, for example, by promoting de-escalation of antibiotics
based on culture results. Insights in the perceptions, attitudes and
interactions of the clinical, nursing and laboratory staff are there-
fore helpful to guide and prepare interventions [43,44]. In line with
what has proved to be successful in malaria treatment, joint
training for clinicians and laboratory staff are recommended [45].
Further, the overarchingQMS of the hospital can be used to connect
for support in logistics (transport, procurement, maintenance,
biosafety and waste management) and staff management (training,
orientation and evaluation).
Start softlydchoose for feasibility and impact
Before formally starting-up a QMS, time to observe and analyse
the laboratory activities must be taken, to get acquainted with the
workflow, terminology and vocabulary, product names and ab-
breviations used as well as with laboratory and hospital staff and
the healthcare's context. As noted elsewhere, personal interactions
provides a solid basis for collaboration [46].
Starting with a project that can be easily accomplished and has a
high impact is recommended [6]. Topics can be found close to the
work space and include for instance biosafety (rational use of
gloves and masks), labelling of shelves and storage space and
standardization of labelling of consumables. In addition, ‘fewer are
better,’which means that no more than one topic every six months
should be addressed [6].
Keep documents and communication simple and straightforward
Communication must be efficient and adapted to the size and
complexity of the laboratory [6]. Standard operating procedures
(SOPs) will be among the first documents to be written or updated.
A good SOP is presented in an appropriate font type and lay-out
(legible), easy to understand (readable) and conveys clear and
unequivocal information (comprehensible); it presents sufficient
procedural details [47] is pretested and verified [6,48]. Given the
extended templates of QMS-recommended SOPs (CLSI QMS02-A6
template lists 17 sections [49]), so-called bench aids or job aids are
welcome as a quick reference at the work placedprovided docu-
ment control [6,47,48]. The urge for legibility, readability and
comprehensibility also applies to other documents particularly if
used at the workplace: stock cards, check lists, flow diagrams and
graphs. In the African context, the importance and impact of
respectful verbal communication cannot be overemphasized and
occasions for face-to-face interactions with clinicians and other
stakeholders should be fully exploited [47,48].
Learn from your mistakes
Reducing medical errors ranks first among the benefits of a
successful QMS implementation and error review has been the
oldest approach of the ‘Nonconforming Event Management’[7].
Error review consists of tracking errors up to the identification of
root cause(s) and subsequent design and implementation of
corrective and preventive actions [50]. Most errors occur in the pre-
and postexamination processes (about 60% and 25% respectively)
[6,51], but given its manual and subjective workup, clinical bacte-
riology is also vulnerable to errors in the examination phase [52].
Apart from ‘expected’and easily detectable errors (e.g. failing to
comply with SOP, not acting on out-of-range quality controls), there
are hidden errors such as failures of Gram stain reading, species
identification and antimicrobial susceptibility testing [32,53].
In our experience, error review is an excellent portal of entry to
activate QMS and it can be applied from the early phase of
implementation of the QMS, whereas alternative approaches such
as monitoring of quality indicators and internal audits require a
more advanced implementation. Of note, most analytical errors in
clinical bacteriology proved to be related to knowledge and skills
and therefore can be efficiently addressed by teaching, training
and learning [52]. Educational programmes should be straight-
forward, explain the science behind the error and stress the ‘do's
and don'ts'; moreover, overlap and redundancy are appropriate
[47].
Be present at the bench and organize daily supervisory review
Supervision of culture workup is another traditional approach
towards laboratory quality and is particularly relevant for clinical
bacteriology [54]. Supervision at the workplacedin preference at a
daily basis and at a fixed timedis a valuable tool for bench-side
teaching, tuning of operator-subjective examinations (such as
Gram stain) and boosting compliance with SOPs. Daily supervision
also allows for timely detection of procedural deviations such as
unapproved modifications, ill-advised shortcuts and use of
outdated products inserts [47].
Look for locally adapted solutions
A creative mind helps to design local solutions on the road to
ISO 15189. Low-cost low-tech, feasibility and acceptability are key.
As an example, printed request forms may guide the prescriber
towards harmonized indications and relevant requests. Stan-
dardized abbreviations may be agreed upon and recorded. Risks to
sample mismatch and mislabelling of subcultures can be mitigated
by arranging the physical space and workflow at the bench and
sticking to the one-by-one rule used at specimen transfer and
distribution [55]. A particular risk is inoculating multiple isolates
on a single petri agar, which should be limited and well controlled.
Electronic sign-off of documents may be replaced by hand-signing
before or after laboratory meetings. Other tools of traceability
include writing in different colours according to the day of incu-
bation, use of standardized laboratory forms and implementing a
journal passing along information between staff covering night
shifts [6].
Stimulate ownership and create a positive climate
A QMS must be visible in the laboratory and must express
progress and achievements. A clear workplace such as described in
the SLMTA toolkit (Module 1dProductivity management) with
well-designed bench aids displayed is conducive to QMS but also
attractive for staff, trainees and visitors. Staff should be invited to
SOP and document writing and verification, but should not be
overloaded. A constructive and critical attitude including reporting
and reviewing errors should be encouraged. As stated above, lab-
oratory management must assure clear commitment and involve-
ment in the implementation of the QMS, amongst others by visible
presence at meetings and trainings, respecting short feedback
loops and keeping good and timely records [6,50].
Needs and opportunities to extend QMS and training tools to clinical
bacteriology
Existing tools to facilitate QMS (Table 3), such as the WHO AF-
RO's SLMTA toolkit and the WHO, Centers for Disease Control and
Prevention and CLSI Laboratory QMS Training Handbook and
Toolkit can be easily extended with real-life cases of clinical

bacteriologydfor instance in the SLMTA's ‘Meet the Clinician’ac-
tivities and the ‘Clinicians Handbook,’or its modules of specimen
collection, work area management and test result reporting.
Although hardware and network costs remain barriers, imple-
mentation of a LIS has benefits at all three examination processes;
LIS further provides opportunities to educate prescribers, guide
therapeutic decisions and detect hospital infection outbreaks in
real-time. LIS supports other Quality System Essentials such as
purchasing, inventory and assessments (e.g. analysis of corrected
reports as a proxy for near errors) [6,52]. Currently, free-of-charge
LIS are made available (Table 3).
Conclusion
Across sub-Saharan Africa and over the last decade amazing
strides have been made to implement QMS in the laboratory
diagnosis of HIV, malaria and TB. It is now time to extend this
success to clinical bacteriology, given the momentum generated by
the declining burden of malaria and the need to contain the
emergent AMR. Taking into account the particularities of both
clinical bacteriology and the context of low-resource settings,
existing national networks can be strengthened towards compe-
tences in clinical bacteriology and training tools can be adapted to
integrate clinical bacteriology. Best practices can facilitate the
implementation of QMS in clinical bacteriology in hospital settings.
Given the extensions of clinical bacteriology to antibiotic stew-
ardship and infection prevention, this step will ultimately boost a
culture of quality to all sectors of healthcare in low-resource
settings.
