Impact of laboratory accreditation on patient care and the health system

Accreditation of nutrition support teams: A new initiative by the Turkish Society of Clinical Enteral & Parenteral Nutrition

OBJECTIVES

Accreditation is a process to evaluate compliance of an institution or organization with predetermined performance standards, focusing on achieving continuous improvement strategies and optimal quality standards and motivating the accredited organization to do so. There is no established accreditation program for nutrition support teams (NSTs) at national and international levels. In order to increase the standards of NSTs, developing an accreditation program is being planned by the Turkish Society of Clinical Enteral & Parenteral Nutrition (KEPAN).

METHODS

Accreditation standards were developed by a study group under the organization of KEPAN. Minimum standards for composition, qualifications, physical requirements, workflow charts, medical records, and both patient and health care providers' safety measures in NSTs were specified. These standards were uploaded to a computer program, and the necessary infrastructure for a web-based management of accreditation processes was developed.

RESULTS

An organization applying for accreditation should fill in the application form on KEPAN website electronically. Eligibility criteria for accreditation include number of NST members, physical environment, patient monitoring requirements, research, and training. A total of 22 standards are surveyed under 13 sections. These standards contain 61 criteria. To be accredited, each of 22 standards must score >70 and each of 13 sections must score >80.

CONCLUSIONS

In order to increase the quality of nutritional care and improve patient outcomes, an accreditation program has been developed. This program principally sets the basic standards, organizational scheme, and responsibilities of NSTs.

Examining 7 years of implementing quality management systems in medical laboratories in sub-Saharan Africa

BACKGROUND

Achievement of ISO15189 accreditation demonstrates competency of a laboratory to conduct testing. Three programmes were developed to facilitate achievement of accreditation in low- and middle-income countries: Strengthening Laboratory Management Towards Accreditation (SLMTA), Stepwise Laboratory Improvement Process Towards Accreditation (SLIPTA) and Laboratory Quality Stepwise Implementation (LQSI).

OBJECTIVE

To determine the level of accreditation and associated barriers and facilitators among medical laboratories in the WHO-AFRO region by 2020.

METHODS

A desk review of SLIPTA and SLMTA databases was conducted to identify ISO15189-accredited medical laboratories between January 2013 and December 2020. Data on access to the LQSI tool were extracted from the WHO database. Facility and country characteristics were collected for analysis as possible enablers of accreditation. The chi-square test was used to analyse differences with level of significance set at <0.05.

RESULTS

A total of 668 laboratories achieved accreditation by 2020 representing a 75% increase from the number in 2013. Accredited laboratories were mainly in South Africa (n = 396; 55%) and Kenya (n = 106; 16%), two countries with national accreditation bodies. About 16.9% (n = 113) of the accredited laboratories were registered for the SLIPTA programme and 26.6% (n = 178) for SLMTA. Approximately 58,217 LQSI users were registered by December 2020. Countries with a higher UHC index for access to HIV care and treatment, higher WHO JEE scores for laboratory networks, a larger number of registered LQSI users, with national laboratory policy/strategic plans and PEPFAR-priority countries were more likely to have an accredited laboratory. Of the 475 laboratories engaged in the SLIPTA programme, 154 attained ≥4 SLIPTA stars (ready to apply for accreditation) and 113 achieved ISO 15189 accreditation, with 96 enrolled into the SLMTA programme. Lower-tier laboratories were less likely to achieve accreditation than higher-tier laboratories (7.7% vs. 30%) (p < 0.001). The probability of achieving ISO 15189 accreditation (19%) was highest during the first 24 months after enrolment into the SLIPTA programme.

CONCLUSION

To sustainably anchor quality improvement initiatives at facility level, national approaches including access to a national accreditation authority, adoption of national quality standards and regulatory frameworks are required.

Current Developments of Artificial Intelligence in Digital Pathology and Its Future Clinical Applications in Gastrointestinal Cancers

The implementation of DP will revolutionize current practice by providing pathologists with additional tools and algorithms to improve workflow. Furthermore, DP will open up opportunities for development of AI-based tools for more precise and reproducible diagnosis through computational pathology. One of the key features of AI is its capability to generate perceptions and recognize patterns beyond the human senses. Thus, the incorporation of AI into DP can reveal additional morphological features and information. At the current rate of AI development and adoption of DP, the interest in computational pathology is expected to rise in tandem. There have already been promising developments related to AI-based solutions in prostate cancer detection; however, in the GI tract, development of more sophisticated algorithms is required to facilitate histological assessment of GI specimens for early and accurate diagnosis. In this review, we aim to provide an overview of the current histological practices in AP laboratories with respect to challenges faced in image preprocessing, present the existing AI-based algorithms, discuss their limitations and present clinical insight with respect to the application of AI in early detection and diagnosis of GI cancer.

Implementation of a customised antimicrobial resistance laboratory scorecard in Cameroon, Ethiopia and Kenya

Background

In low-resource settings, antimicrobial resistance (AMR) is detected by traditional culture-based methods and ensuring the quality of such services is a challenge. The AMR Scorecard provides laboratories with a technical assessment tool for strengthening the quality of bacterial culture, identification, and antimicrobial testing procedures.

Objective

To evaluate the performance of the AMR Scorecard in 11 pilot laboratory evaluations in three countries also assessed with the Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA) checklist.

Methods

Pilot laboratory evaluations were conducted in Cameroon, Ethiopia and Kenya between February 2019 and March 2019. Assessors with previous SLIPTA and microbiology experience were trained. Assessors performed the laboratory assessments using the SLIPTA and AMR Scorecard tools.

Results

Weaknesses in technical procedures and the quality management systems were identified in all areas and all laboratories. Safety had the highest mean performance score (SLIPTA: 68%; AMR Scorecard: 73%) while management review had the lowest (SLIPTA: 32%; AMR Scorecard: 8%) across all laboratories. The AMR Scorecard scores were generally consistent with SLIPTA scores. The AMR Scorecard identified technical weaknesses in AMR testing, and SLIPTA identified weaknesses in the quality management systems in the laboratories.

Conclusion

Since the AMR Scorecard identified important gaps in AMR testing not detected by SLIPTA, it is recommended that microbiology laboratories use SLIPTA and the AMR Scorecard in parallel when preparing for accreditation. Expanding the use of the AMR Scorecard is a priority to address the need for quality clinical microbiology laboratory services in support of optimal patient care and AMR surveillance.

Private sector engagement in the COVID-19 response: experiences and lessons from the Democratic Republic of Congo, Nigeria, Senegal and Uganda

BACKGROUND

Private entities play a major role in health globally. However, their contribution has not been fully optimized to strengthen delivery of public health services. The COVID-19 pandemic has overwhelmed health systems and precipitated coalitions between public and private sectors to address critical gaps in the response. We conducted a study to document the public and private sector partnerships and engagements to inform current and future responses to public health emergencies.

METHODS

This was a multi-country cross-sectional study conducted in the Democratic Republic of Congo, Nigeria, Senegal and Uganda between November 2020 and March 2021 to assess responses to the COVID-19 pandemic. We conducted a scoping literature review and key informant interviews (KIIs) with private and public health sector stakeholders. The literature reviewed included COVID-19 country guidelines and response plans, program reports and peer-reviewed and non-peer-reviewed publications. KIIs elicited information on country approaches and response strategies specifically the engagement of the private sector in any of the strategic response operations.

RESULTS

Across the 4 countries, private sector strengthened laboratory systems, COVID-19 case management, risk communication and health service continuity. In the DRC and Nigeria, private entities supported contact tracing and surveillance activities. Across the 4 countries, the private sector supported expansion of access to COVID-19 testing services through establishing partnerships with the public health sector albeit at unregulated fees. In Senegal and Uganda, governments established partnerships with private sector to manufacture COVID-19 rapid diagnostic tests. The private sector also contributed to treatment and management of COVID-19 cases. In addition, private entities provided personal protective equipment, conducted risk communication to promote adherence to safety procedures and health promotion for health service continuity. However, there were concerns related to reporting, quality and cost of services, calling for quality and price regulation in the provision of services.

CONCLUSIONS

The private sector contributed to the COVID-19 response through engagement in COVID-19 surveillance and testing, management of COVID-19 cases, and health promotion to maintain health access. There is a need to develop regulatory frameworks for sustainable public-private engagements including regulation of pricing, quality assurance and alignment with national plans and priorities during response to epidemics.

Enhancing accreditation outcomes for medical laboratories on the Strengthening Laboratory Management Toward Accreditation programme in Kenya via a rapid results initiative

Background

Since 2010, Kenya has used SLIPTA to prepare and improve quality management systems in medical laboratories to achieve ISO 15189 accreditation. However, less than 10% of enrolled laboratories had done so in the initial seven years of SLMTA implementation.

Objective

We described Kenya’s experience in accelerating medical laboratories on SLMTA to attain ISO 15189 accreditation.

Methods

From March 2017 to July 2017, an aggressive top-down approach through high-level management stakeholder engagement for buy-in, needs-based expedited SLIPTA mentorship and on-site support as a rapid results initiative (RRI) was implemented in 39 laboratories whose quality improvement process had stagnated for 2–7 years. In July 2017, SLIPTA baseline and exit audit average scores on quality essential elements were compared to assess performance.

Results

After RRI, laboratories achieving greater than a 2-star SLMTA rating increased significantly from 15 (38%) at baseline to 33 (85%) (p < 0.001). Overall, 34/39 (87%) laboratories received ISO 15189 accreditation within two years of RRI, leading to a 330% increase in the number of accredited laboratories in Kenya. The most improved of the 12 quality system essentials were Equipment Management (mean increase 95% CI: 5.31 ± 1.89) and Facilities and Biosafety (mean increase [95% CI: 4.05 ± 1.78]) (both: p < 0.0001). Information Management and Corrective Action Management remained the most challenging to improve, despite RRI interventions.

Conclusion

High-level advocacy and targeted mentorship through RRI dramatically improved laboratory accreditation in Kenya. Similar approaches of strengthening SLIPTA implementation could improve SLMTA outcomes in other countries with similar challenges.

What factors are associated with improvements in productivity in clinical laboratories in the Asia Pacific Region?

INTRODUCTION

Clinical laboratories usually have a quality management system such as ISO 15189, which provides a framework for quality and competence to perform medical testing and internal systems such as audit and nonconformance to ensure consistent processes. However, organizations need to have access to internal procedures and external competitors' performance to improve their operations. These are often seen as commercial or areas where it is difficult to agree on an acceptable goal.

METHOD

In 2019, 1158 laboratories from 17 countries/regions in the Asia Pacific Region answered the survey, including 399 Chinese sites. The survey collected information on quality, turnaround time and productivity.

RESULTS

Median productivity for laboratories in the Asia Pacific Region not including Chinese sites was 25 samples/FTE/day for small laboratories (workload: <250 samples/day), 100 for medium-sized laboratories (workload: 251-1000 samples/day) and 220 for large laboratories (workload: >1001 samples/day). The parameters associated with increased productivity in some laboratories were automation, middleware, Lean Six Sigma quality improvement activities and International Accreditation.

CONCLUSION

This survey provides evidence of an association of quality improvement activities on laboratory productivity. There are differences in the effect of these activities in Chinese and non-Chinese laboratories in the Asia Pacific Region. The survey confirmed that the implementation of automation is associated with increased median productivity in all sites. Implementation of Lean Six Sigma and International Accreditation is associated with increased productivity in large laboratories.

Implementation of a Quality and Patient Safety Curriculum for Pathology Residency Training

Quality and Patient Safety education for resident physicians is necessary to prepare them for independent practice and to meet accreditation requirements. Integrating such education into the residents’ routine work can provide them with valuable practical experience, while advancing the institution’s quality priorities. We committed to Quality and Patient Safety education for our pathology residents but found no published program that met their specific needs. To fill this gap in pathology residency education, we designed and implemented a new curriculum that spans the 4-year duration of residency training. Curriculum content was drawn from the pathology milestones, and educational strategies were based on the principles of adult learning. The curriculum was implemented in the 2018 to 19 academic year, and residents were assessed before and after their participation. The residents engaged in several Quality and Patient Safety activities and projects under faculty supervision, and improved their scores on objective assessments (Quality and Patient Safety quiz and in-service examination). Implementation was facilitated by a Quality and Patient Safety chief resident, and the recruitment of faculty with demonstrated Quality and Patient Safety interest. Our comprehensive Quality and Patient Safety curriculum is feasible to implement and can help pathology residents develop the knowledge and skills needed to lead quality initiatives. We believe that the curriculum framework is readily adaptable to other residency programs.

Investigation of the long-term yield of auditing for conformity with the ISO 15189:2012 quality standard in a hospital pathology laboratory

Introduction

Pathology laboratories are increasingly seeking accreditation to quality standards to assure Quality of Service (QoS). However, there is little data available regarding the value of this in laboratories with well-established Quality Management Systems (QMS). Moreover, critics of accreditation claim it redirects resources toward trivial issues. Our objective was to investigate the value of auditing for conformity with the ISO 15189:2012 standard in such laboratories.

Design

and Methods: In total, 483 Audit-Identified Non-Conformities (AINCs) were documented within our department since transitioning to an ISO 15189:2012 compliant QMS. The potential consequences of these were assessed by three clinical laboratorians who assigned them into categories based on their likely impact. These were: Unlikely (no clear consequences); Possible (potential for poor QoS/harm); and Probable (Likely to cause poor QoS/harm). Additionally, total numbers/severity of Real-Time Non-Conformities (RTNCs) detected outside of auditing were examined to provide additional insight into the effects of accreditation on QoS.

Results

According to majority decision: 395 (81.8%) of AINCs were classified Unlikely, 88 (18.2%) were Possible, and none were Probable. The relative proportion of Unlikely AINCs also rose over time. Total numbers and severity of RTNCs dropped in the short-term following transition to an ISO 15189:2012 QMS, but steadily rose thereafter.

Conclusions

Our data suggest auditing for conformity with ISO 15189:2012 standards may be effective in attaining accreditation, but may have diminishing returns in the long-term once the QMS is established, unless there is continual improvement in the audit process to promote better use of resources.

Evaluation results of national hospital accreditation program in Iran: The view of hospital managers

BACKGROUND

Accreditation programs have a crucial role in improving the safety and effectiveness of hospital services. Many factors contribute to achieve accreditation goals. This study evaluated the national Iranian hospital accreditation program from the view of hospital managers in Iran.

METHODS

The study was conducted in 2015 using a validated questionnaire designed to collect feedback concerning accreditation processes and impacts. In total, 547 managers were surveyed using a stratified random sampling method. A 5-degree scale Likert from totally disagree=1 to totally agree=5 has been used for the evaluation. Descriptive and inferential statistics were used to analyze the data.

RESULTS

Approximately half of hospital managers were satisfied with the accreditation standards and surveying methods. The reason for their dissatisfaction was the high number of measures (2.38). The main challenges to the accreditation method were reported inadequate surveyor training (2.94) their satisfaction with the infrastructure was low because of a lack of hospital resources. Nonetheless, the accreditation program was perceived as being successful in improving patient safety (3.80), patient compliance (3.72), and error reduction (3.53).

CONCLUSION

An effective accreditation program requires reducing the number of standards and making them clearer as well as the infrastructure for the implementation of accreditation such as sufficient and sustainable funds, enough human resources and equipment should be provided. Appropriate surveyors should be selected and trained professionally to ensure inter-rater reliability among them.

Clinical Referral Laboratory Personnel's Perception of Challenges and Strategies for Sustaining the Laboratory Quality Management System

OBJECTIVES

To explore challenges explaining the decrease in quality performance and suggest strategies to improve and sustain laboratory quality services.

METHODS

Twenty key informants' interviews from laboratory personnel were conducted in five laboratories. Four had previously shown a decrease in quality performance. Interviews were transcribed verbatim and analyzed using inductive thematic analysis.

RESULTS

Two themes emerged: (1) insufficient coordination and follow-up system towards accreditation, where lack of coordination, follow-up, and audits explained the decrease in performance; (2) inadequate resource optimization, where insufficient knowledge in Laboratory Quality Management System (LQMS), ownership by laboratory workforce, and insufficient stakeholders' communication contributed to low-quality performance.

CONCLUSIONS

The coordination, follow-up, and assessments of LQMS, in conjunction with training of laboratory workforce, would establish an institutional culture of continuous quality improvement (CQI) towards accreditation and sustainment of quality health care. To achieve CQI culture, routine gap checking and planning for improvement using a system approach is required.

Introduction of quality management in a National Reference Laboratory in Germany

Background

High quality diagnostic services are crucial for tuberculosis (TB) diagnosis, treatment and control. A strong laboratory quality management system (QMS) is critical to ensuring the quality of testing and results. Recent initiatives to improve TB laboratory quality have focused on low and middle-income countries, but similar issues also apply to high-income countries.

Methods and findings

Using a multipronged approach reviews of facilities, equipment, processes (purchasing, pre-analytic, analytic and post-analytic), staff, health and safety, documentation, information management and organization based on the ISO 15189 and the twelve quality system essentials were conducted between October 2015 and January 2016 at the National TB Reference Laboratory in Germany. Outcome assessment included proportion of smear positive slides, proportion of contaminated liquid cultures and DNA contamination rates before and after implementation of QMS. The odds ratio for these outcomes was calculated using a before/after comparison. Reviews highlighted deficiencies across all twelve quality system essentials and were addressed in order of priority and urgency. Actions aimed at improving analytical quality, health and safety and information management were prioritised for initial implementation in parallel with each other. The odds ratio for a sample to be tested as microscopically positive increased by 2.08 (95%CI 1.41–3.06) comparing the time before with the time after implementation of quality managed fluorescence microscopy. Liquid culture contamination rates decreased from 23.6- 7.6% in April-July 2016 to <10% in November 2017-March 2018. The proportion of negative controls showing evidence of DNA contamination decreased from 38.2% in 2013 to 8.1% in 2017, the corresponding odds ratio was 0.14 (95%CI 0.07–0.29).

Conclusion

This study showed marked improvement on quality indicators after implementation of a QMS in a National TB Reference Laboratory. The challenges and lessons learned in this study are valuable not just for high-income settings, but are equally generalizable to other laboratories.

Medical laboratory accreditation in a resource-limited district health centre laboratory, Addis Ababa, Ethiopia

Background

Improving the quality of medical laboratory services is a high priority in many countries. However, quality management systems for laboratories in resource-limited settings are often inadequate.

Objectives

This article shares the experiences, benefits and challenges of the laboratory journey towards accreditation in a primary healthcare laboratory in Addis Ababa, Ethiopia.

Methods

A retrospective review of laboratory records in Addis Ketema Health Center was conducted from 2012 to 2015. The study was supplemented by observations from some of the authors of this article who worked in the laboratory.

Results

The laboratory journey towards accreditation began with a baseline assessment in 2012 using the World Health Organization African Region Stepwise Laboratory Quality Improvement Process Towards Accreditation; the baseline score was 78 points (0 stars). After mentorship support, the laboratory improved to 198 points (3 stars) in 2013 and 249 points (5 stars) in 2014. The laboratory scaled up to International Organization for Standardization 15189 requirements and received limited-scope accreditation for tuberculosis sputum microscopy and hematology tests in 2015. After adopting and implementing the standards, steady improvement was observed in the reliability of the laboratory services. Lack of resources was the major challenge the laboratory encountered.

Conclusion

Even though a remarkable quality performance improvement was observed over the entire process, inadequate skilled personnel was the major challenge identified in the road towards accreditation. Therefore, an appropriate, workload-based staffing structure should be developed to improve and sustain medical laboratory quality standards in resource-limited settings.

Survey-Defined and Interview-Elicited Challenges That Faced Ethiopian Government Hospital Laboratories as They Applied ISO 15189 Accreditation Standards in Resource-Constrained Settings in 2017

OBJECTIVES

The World Health Organization African Regional Office recommends ISO 15189 standards to improve performance quality in sub-Saharan African laboratories. We specify challenges Ethiopian laboratorians encountered applying ISO 15189 standards.

METHODS

From a structured survey at 12 Ethiopian government hospitals, 175 laboratory staff replied; all were aware of the ISO standards and 138 had been involved in the ISO 15189 inspection process. In addition, 11 laboratory heads, 10 quality officers, and three medical directors were interviewed in depth.

RESULTS

Half or more respondents identified six challenges obstructing accreditation to a "large" or "very large" degree: (1) low management support, (2) inadequate training, (3) insufficient infrastructure, (4) excessive documentation, (5) little mentorship, and (6) increased accreditation-related workload. Interviewees added (7) poor equipment, (8) unavailable/poor-quality reagents, and (9) high staff turnover.

CONCLUSIONS

The survey and interviews specified nine major challenges for Ethiopian government hospital laboratories that seriously obstruct meeting ISO 15189 demands.

Clinical Referral Laboratories in Rwanda

Objectives

We investigated the quality system performance in Rwandan referral laboratories to determine their progress toward accreditation.

Methods

We conducted audits across five laboratories in 2017, using the Stepwise Laboratory Quality Improvement Process Towards Accreditation checklist. Laboratories were scored based on the World Health Organization grading scale (0-5 stars scale) and compared with earlier audits.

Results

Between 2012 and 2017, only one laboratory progressed (from four to five stars). Four of the five laboratories decreased to one (three laboratories) and zero (one laboratory) stars from four and three stars. Management reviews, evaluation, audits, documents, records, and identification of nonconformities showed a low performance.

Conclusions

Four of five laboratories are not moving toward accreditation. However, this target is still achievable by energizing responsibilities of stakeholders and monitoring and evaluation. This would be possible because of the ability that laboratories showed in earlier audits, coupled with existing health policy that enables sustainable quality health care in Rwanda.

Factors which contributed for low quality sputum smears for the detection of acid fast bacilli (AFB) at selected health centers in Ethiopia: A quality control perspective

Objectives

Quality of tuberculosis (TB) microscopy diagnosis is not a guarantee despite implementation of External Quality Assurance (EQA) service in all laboratories of health facilities. Hence, we aimed at evaluating the technical quality and the findings of sputum smear microscopy for acid fast bacilli (AFB) at health centers in Hararge Zone, Oromia Region, Ethiopia.

Methods

A cross-sectional study was carried out between July 8, 2014 and July 7, 2015.A pre-tested structured questionnaire was used to collect data. Lot Quality Assurance Sampling (LQAS) method was put into practice for collecting all necessary sample slides. Data were analyzed by using SPSS (Statistical Package for Social Sciences) version 20 software. P-value < 0.05 was considered as statistically significant.

Results

Of the total55 health center laboratories which had been assessed during the study period, 20 (36.4%) had major technical errors; 13 (23.6%) had 15 false negative results and 17 (30.9%) had 22 false positive results. Moreover, poor specimen quality, smear size, smear thickness, staining and evenness were indicated in 40 (72.7%), 39 (70.9%), 37 (67.3%), 27(49.1%) and 37 (67.3%) of the collected samples, respectively. False negative AFB findings were significantly associated with lack of Internal Quality Control (IQC) measures (AOR (Adjusted Odds Ratio): 2.90 (95% CI (Confidence Interval): 1.25,6.75) and poor staining procedures (AOR: 2.16(95% CI: 1.01, 5.11).

Conclusions

The qualities of AFB smear microscopy reading and smearing were low in most of the laboratories of the health centers. Therefore, it is essential to strength EQA program through building the capacity of laboratory professionals.

Improving Laboratory Efficiency in the Caribbean to Attain the World Health Organization HIV Treat All Recommendations

Scientific evidence showing the benefits of early initiation of antiretroviral therapy (ART) prompted World Health organization (WHO) to recommend that all persons diagnosed as HIV positive should commence ART irrespective of CD4 count and disease progression. Based on this recommendation, countries should adopt and implement the HIV "Treat All" policy to achieve the UNAIDS 90-90-90 targets and ultimately reach epidemic control. Attaining this goal along the HIV treatment cascade depends on the laboratory to monitor progress and measure impact. The laboratory plays an important role in HIV diagnosis to attain the first 90 and in viral load (VL) and HIV drug resistance testing to reinforce adherence, improve viral suppression, and measure the third 90. Countries in the Caribbean region have endorsed the WHO HIV "Treat all" recommendation; however, they are faced with diminishing financial resources to support laboratory testing, seen as a rate-limiting factor to achieving this goal. To improve laboratory coverage with fewer resources in the Caribbean there is the need to optimize laboratory operations to ensure the implementation of high quality, less expensive evidence-based approaches that will result in more efficient and effective service delivery. Suggested practical and innovative approaches to achieve this include: (1) targeted testing within HIV hotspots; (2) strengthening sample referral systems for VL; (3) better laboratory data collection systems; and (4) use of treatment cascade data for programmatic decision-making. Furthermore, strengthening quality improvement and procurement systems will minimize diagnostic errors and guarantee a continuum of uninterrupted testing which is critical for routine monitoring of patients to meet the stated goal.

External quality assessment in resource-limited countries

Introduction

Health laboratory services are a critical component of national health systems but face major operational challenges in resource-limited (RL) settings. New funding for health systems strengthening in RL countries has increased the demand for diagnostics and provided opportunities to address these constraints. An approach to sustainably strengthen national laboratory systems in sub-Saharan African countries is the Strengthening Laboratory Management Toward Accreditation (SLMTA) programme. External Quality Assessment (EQA) is a requirement for laboratory accreditation. EQA comprises proficiency testing (PT), rechecking of samples and on-site evaluation.

Materials and methods

A systematic literature search was conducted to identify studies addressing laboratory EQA and quality monitoring in RL countries. Unpublished reports were also sought from national laboratory authorities and personnel.

Results

PT schemes in RL countries are provided by commercial companies, institutions in developed countries and national programmes. Most government-supported PT schemes address single diseases using a vertical approach. Regional approaches to delivering PT have also been implemented across RL countries. Rechecking schemes address mainly tuberculosis (TB), malaria and human immunodeficiency virus (HIV); integrated rechecking programmes have been piloted. Constraints include sample transportation, communication of results, unknown proficiency of referee staff and limited resources for corrective action. Global competency assessment standards for malaria microscopists have been established.

Conclusions

EQA is vital for monitoring laboratory performance and maintaining quality of laboratory services, and is a valuable tool for identifying and assessing technology in use, identifying gaps in laboratory performance and targeting training needs. Accreditation of PT providers and competency of EQA personnel must be ensured.

Assessment of three medical and research laboratories using WHO AFRO_SLIPTA Quality Standards in Southwestern Uganda: a long way to go

Introduction

While the laboratory represents more than 70% of clinical diagnosis and patient management, access to reliable and quality laboratory diagnostics in sub-Saharan Africa remains a challenge. To gain knowledge and suggest evidence based interventions towards laboratory improvement in Southwestern Uganda, we assessed the baseline laboratory quality standards in three medical and research laboratories in Southwestern Uganda.

Methods

We conducted a cross sectional survey from October, 2013 to April, 2014. Selected laboratories, including one private research, one private for profit and one public laboratory, were assessed using the WHO AFRO_SLIPTA checklist and baseline scores were determined.

Results

The three laboratories assessed met basic facility requirements, had trained personnel, and safety measures in place. Sample reception was properly designed and executed with a well designated chain of custody. All laboratories had sufficient equipment for the nature of work they were involved in. However, we found that standard operating procedures were incomplete in all three laboratories, lack of quality audit schemes by two laboratories and only one laboratory enrolled into external quality assurance schemes. The SLIPTA scores were one star for the research laboratory and no star for both the public and private-for-profit laboratories.

Conclusion

While most of the laboratory systems were in place, the low scores obtained by the assessed laboratories reflect the need for improvement to reach standards of quality assured diagnostics in the region. Therefore, routine mentorship and regional supportive supervision are necessary to increase the quality of laboratory services.

Fast Track to Accreditation: An Implementation Review of College of American Pathologists and International Organization for Standardization 15189 Accreditation

CONTEXT

- This review examines challenges and opportunities in preparing laboratories in a startup phase for accreditation by both the College of American Pathologists (CAP) and International Organization for Standardization (ISO) 15189 in an international setting as it relates to our experience at Cleveland Clinic Abu Dhabi Laboratory. It also discusses some of the strategies used in executing those projects and the added advantages in pursuing both types of accreditations.

OBJECTIVES

- To share our experience with CAP and ISO 15189 accreditations in a startup international operation in relation to the challenges encountered and implementation strategy success factors.

DATA SOURCES

- MEDLINE (PubMed) database was used to review this topic as well as peer-reviewed articles and World Health Organization publications on the topic.

CONCLUSIONS

- Accreditation is a perfect means toward building quality medical laboratories in a diverse workforce environment and improving patient safety. Further, it establishes a strong foundation on which any new operation can build a sustainable quality improvement culture. Accreditations by CAP and/or ISO are among the most reputable and well-established accreditation systems that clinical laboratories could aim for. As a result of both accreditations offering synergistic and complementing features, we recommend that any laboratory seeking excellence in quality and performance should consider exploring both. Key elements to success include having dedicated project management and change management support while preparing for accreditation. Laboratories seeking accreditation in early operational stages may face a number of challenges; however, significant opportunities will also be present to optimize various operational components from the beginning.

Diagnostic Laboratories in India: Investigating Quality Characteristics, Productivity and Time of Reporting

This is the result of a Survey of diagnostics laboratories in the Asia Pacific (APAC) region with perspectives on India, investigating the three key aspects that are central to the success of a laboratory: quality, cost and speed. This Survey provides a comparison in selected performance indicators in a large number of diagnostic laboratories in a broad range of countries in the APAC region. The Survey provides data on some key performance characteristics such as quality improvement activities, staff productivity and Turnaround Time (TAT). This Survey also demonstrates in India the common issues facing all the laboratories surveyed but also common solutions using a Quality Systems approach which involves Accreditation, customer responsiveness, greater use of IT, automation and Lean principles. Indian laboratories reported less automation and fewer laboratories have Laboratory Information Systems. The productivity by various measures in Indian laboratories was less than in other APAC laboratories. TAT was more commonly monitored in the Indian specimens though there were fewer laboratories compared with the APAC specimens where there were separate TATs for Short Turnaround Time and Routine specimens.

Implementation of quality management for clinical bacteriology in low-resource settings

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. Successful 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 challenges 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, stimulating 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.

Implementation of quality management systems and progress towards accreditation of National Tuberculosis Reference Laboratories in Africa

Background

Laboratory services are essential at all stages of the tuberculosis care cascade, from diagnosis and drug resistance testing to monitoring response to treatment. Enabling access to quality services is a challenge in low-resource settings. Implementation of a strong quality management system (QMS) and laboratory accreditation are key to improving patient care.

Objectives

The study objective was to determine the status of QMS implementation and progress towards accreditation of National Tuberculosis Reference Laboratories (NTRLs) in the African Region.

Method

An online questionnaire was administered to NTRL managers in 47 World Health Organization Regional Office for Africa member states in the region, between February and April 2015, regarding the knowledge of QMS tools and progress toward implementation to inform strategies for tuberculosis diagnostic services strengthening in the region.

Results

A total of 21 laboratories (43.0%) had received SLMTA/TB-SLMTA training, of which 10 had also used the Global Laboratory Initiative accreditation tool. However, only 36.7% of NTRLs had received a laboratory audit, a first step in quality improvement. Most NTRLs participated in acid-fast bacilli microscopy external quality assurance (95.8%), although external quality assurance for other techniques was lower (60.4% for first-line drug susceptibility testing, 25.0% for second-line drug susceptibility testing, and 22.9% for molecular testing). Barriers to accreditation included lack of training and accreditation programmes. Only 28.6% of NTRLs had developed strategic plans and budgets which included accreditation.

Conclusion

Good foundations are in place on the continent from which to scale up accreditation efforts. Laboratory audits should be conducted as a first step in developing quality improvement action plans. Political commitment and strong leadership are needed to drive accreditation efforts; advocacy will require clear evidence of patient impact and cost-benefit.

Mozambique's journey toward accreditation of the National Tuberculosis Reference Laboratory

Background

Internationally-accredited laboratories are recognised for their superior test reliability, operational performance, quality management and competence. In a bid to meet international quality standards, the Mozambique National Institute of Health enrolled the National Tuberculosis Reference Laboratory (NTRL) in a continuous quality improvement process towards ISO 15189 accreditation. Here, we describe the road map taken by the NTRL to achieve international accreditation.

Methods

The NTRL adopted the Strengthening Laboratory Management Toward Accreditation (SLMTA) programme as a strategy to implement a quality management system. After SLMTA, the Mozambique National Institute of Health committed to accelerate the NTRL’s process toward accreditation. An action plan was designed to streamline the process. Quality indicators were defined to benchmark progress. Staff were trained to improve performance. Mentorship from an experienced assessor was provided. Fulfilment of accreditation standards was assessed by the Portuguese Accreditation Board.

Results

Of the eight laboratories participating in SLMTA, the NTRL was the best-performing laboratory, achieving a 53.6% improvement over the SLMTA baseline conducted in February 2011 to the Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA) assessment in June 2013. During the accreditation assessment in September 2014, 25 minor nonconformities were identified and addressed. In March 2015, the NTRL received Portuguese Accreditation Board recognition of technical competency for fluorescence smear microscopy, and solid and liquid culture. The NTRL is the first laboratory in Mozambique to achieve ISO 15189 accreditation.

Conclusions

From our experience, accreditation was made possible by institutional commitment, strong laboratory leadership, staff motivation, adequate infrastructure and a comprehensive action plan.

Developing a customised approach for strengthening tuberculosis laboratory quality management systems toward accreditation

Background

Quality-assured tuberculosis laboratory services are critical to achieve global and national goals for tuberculosis prevention and care. Implementation of a quality management system (QMS) in laboratories leads to improved quality of diagnostic tests and better patient care. The Strengthening Laboratory Management Toward Accreditation (SLMTA) programme has led to measurable improvements in the QMS of clinical laboratories. However, progress in tuberculosis laboratories has been slower, which may be attributed to the need for a structured tuberculosis-specific approach to implementing QMS. We describe the development and early implementation of the Strengthening Tuberculosis Laboratory Management Toward Accreditation (TB SLMTA) programme.

Development

The TB SLMTA curriculum was developed by customizing the SLMTA curriculum to include specific tools, job aids and supplementary materials specific to the tuberculosis laboratory. The TB SLMTA Harmonized Checklist was developed from the World Health Organisation Regional Office for Africa Stepwise Laboratory Quality Improvement Process Towards Accreditation checklist, and incorporated tuberculosis-specific requirements from the Global Laboratory Initiative Stepwise Process Towards Tuberculosis Laboratory Accreditation online tool.

Implementation

Four regional training-of-trainers workshops have been conducted since 2013. The TB SLMTA programme has been rolled out in 37 tuberculosis laboratories in 10 countries using the Workshop approach in 32 laboratories in five countries and the Facility-based approach in five tuberculosis laboratories in five countries.

Conclusion

Lessons learnt from early implementation of TB SLMTA suggest that a structured training and mentoring programme can build a foundation towards further quality improvement in tuberculosis laboratories. Structured mentoring, and institutionalisation of QMS into country programmes, is needed to support tuberculosis laboratories to achieve accreditation.

Development and implementation of the Caribbean Laboratory Quality Management Systems Stepwise Improvement Process (LQMS-SIP) Towards Accreditation

BACKGROUND

Implementing quality management systems and accrediting laboratories in the Caribbean has been a challenge.

OBJECTIVES

We report the development of a stepwise process for quality systems improvement in the Caribbean Region.

METHODS

The Caribbean Laboratory Stakeholders met under a joint Pan American Health Organization/US Centers for Disease Control and Prevention initiative and developed a user-friendly framework called 'Laboratory Quality Management System - Stepwise Improvement Process (LQMS-SIP) Towards Accreditation' to support countries in strengthening laboratory services through a stepwise approach toward fulfilling the ISO 15189: 2012 requirements.

RESULTS

This approach consists of a three-tiered framework. Tier 1 represents the minimum requirements corresponding to the mandatory criteria for obtaining a licence from the Ministry of Health of the participating country. The next two tiers are quality improvement milestones that are achieved through the implementation of specific quality management system requirements. Laboratories that meet the requirements of the three tiers will be encouraged to apply for accreditation. The Caribbean Regional Organisation for Standards and Quality hosts the LQMS-SIP Secretariat and will work with countries, including the Ministry of Health and stakeholders, including laboratory staff, to coordinate and implement LQMS-SIP activities. The Caribbean Public Health Agency will coordinate and advocate for the LQMS-SIP implementation.

CONCLUSION

This article presents the Caribbean LQMS-SIP framework and describes how it will be implemented among various countries in the region to achieve quality improvement.

Global Introduction of New Multidrug-Resistant Tuberculosis Drugs-Balancing Regulation with Urgent Patient Needs

New treatments for multidrug-resistant tuberculosis (MDR TB) are urgently needed. Two new drugs, bedaquiline and delamanid, have recently been released, and several new drugs and treatment regimens are in the pipeline. Misuse of TB drugs is a principal cause of drug resistance. As new drugs and regimens reach the market, the need to make them available to patients must be balanced with regulation of their use so that resistance to the new drugs can be prevented. To foster the rational use of new drugs, we propose 1) expanding/strengthening the capacity for drug susceptibility testing, beginning with countries with a high TB burden; 2) regulating prescribing practices by banning over-the-counter sale of TB drugs and enacting an accreditation system whereby providers must be certified to prescribe new drugs; and 3) decentralizing MDR TB care in rural communities by employing trained community health workers, using promising mobile technologies, and enlisting the aid of civil society organizations.

Implementation research: a mentoring programme to improve laboratory quality in Cambodia

OBJECTIVE

To implement a mentored laboratory quality stepwise implementation (LQSI) programme to strengthen the quality and capacity of Cambodian hospital laboratories.

METHODS

We recruited four laboratory technicians to be mentors and trained them in mentoring skills, laboratory quality management practices and international standard organization (ISO) 15189 requirements for medical laboratories. Separately, we trained staff from 12 referral hospital laboratories in laboratory quality management systems followed by tri-weekly in-person mentoring on quality management systems implementation using the LQSI tool, which is aligned with the ISO 15189 standard. The tool was adapted from a web-based resource into a software-based spreadsheet checklist, which includes a detailed action plan and can be used to qualitatively monitor each laboratory's progress. The tool - translated into Khmer - included a set of quality improvement activities grouped into four phases for implementation with increasing complexity. Project staff reviewed the laboratories' progress and challenges in weekly conference calls and bi-monthly meetings with focal points of the health ministry, participating laboratories and local partners. We present the achievements in implementation from September 2014 to March 2016.

FINDINGS

As of March 2016, the 12 laboratories have completed 74-90% of the 104 activities in phase 1, 53-78% of the 178 activities in phase 2, and 18-26% of the 129 activities in phase 3.

CONCLUSION

Regular on-site mentoring of laboratories using a detailed action plan in the local language allows staff to learn concepts of quality management system and learn on the job without disruption to laboratory service provision.

Implementation of HIV and Tuberculosis Diagnostics: The Importance of Context

BACKGROUND

Novel diagnostics have been widely applied across human immunodeficiency virus (HIV) and tuberculosis prevention and treatment programs. To achieve the greatest impact, HIV and tuberculosis diagnostic programs must carefully plan and implement within the context of a specific healthcare system and the laboratory capacity.

METHODS

A workshop was convened in Cape Town in September 2014. Participants included experts from laboratory and clinical practices, officials from ministries of health, and representatives from industry.

RESULTS

The article summarizes best practices, challenges, and lessons learned from implementation experiences across sub-Saharan Africa for (1) building laboratory programs within the context of a healthcare system; (2) utilizing experience of clinicians and healthcare partners in planning and implementing the right diagnostic; and (3) evaluating the effects of new diagnostics on the healthcare system and on patient health outcomes.

CONCLUSIONS

The successful implementation of HIV and tuberculosis diagnostics in resource-limited settings relies on careful consideration of each specific context.

Implementation of the World Health Organization Regional Office for Africa Stepwise Laboratory Quality Improvement Process Towards Accreditation

Background

The increase in disease burden has continued to weigh upon health systems in Africa. The role of the laboratory has become increasingly critical in the improvement of health for diagnosis, management and treatment of diseases. In response, the World Health Organization Regional Office for Africa (WHO AFRO) and its partners created the WHO AFRO Stepwise Laboratory (Quality) Improvement Process Towards Accreditation (SLIPTA) program.

SLIPTA implementation process

WHO AFRO defined a governance structure with roles and responsibilities for six main stakeholders. Laboratories were evaluated by auditors trained and certified by the African Society for Laboratory Medicine. Laboratory performance was measured using the WHO AFRO SLIPTA scoring checklist and recognition certificates rated with 1–5 stars were issued.

Preliminary results

By March 2015, 27 of the 47 (57%) WHO AFRO member states had appointed a SLIPTA focal point and 14 Ministers of Health had endorsed SLIPTA as the desired programme for continuous quality improvement. Ninety-eight auditors from 17 African countries, competent in the Portuguese (3), French (12) and English (83) languages, were trained and certified. The mean score for the 159 laboratories audited between May 2013 and March 2015 was 69% (median 70%; SD 11.5; interquartile range 62–77). Of these audited laboratories, 70% achieved 55% compliance or higher (2 or more stars) and 1% scored at least 95% (5 stars). The lowest scoring sections of the WHO AFRO SLIPTA checklist were sections 6 (Internal Audit) and 10 (Corrective Action), which both had mean scores below 50%.

Conclusion

The WHO AFRO SLIPTA is a process that countries with limited resources can adopt for effective implementation of quality management systems. Political commitment, ownership and investment in continuous quality improvement are integral components of the process.

The status of medical laboratory towards of AFRO-WHO accreditation process in government and private health facilities in Addis Ababa, Ethiopia

Introduction

The World Health Organization Regional Office for Africa (WHO AFRO) introduces a step wise incremental accreditation approach to improving quality of laboratory and it is a new initiative in Ethiopia and activities are performed for implementation of accreditation program.

Methods

Descriptive cross sectional study was conducted in 30 laboratory facilities including 6 laboratory sections to determine their status towards of accreditation using WHO AFRO accreditation checklist and 213 laboratory professionals were interviewed to assess their knowledge on quality system essentials and accreditation in Addis Ababa Ethiopia.

Results

Out of 30 laboratory facilities 1 private laboratory scored 156 (62%) points, which is the minimum required point for WHO accreditation and the least score was 32 (12.8%) points from government laboratory. The assessment finding from each section indicate that 2 Clinical chemistry (55.2% & 62.8%), 2 Hematology (55.2% & 62.8%), 2 Serology (55.2% & 62.8%), 2 Microbiology (55.2% & 62.4%), 1 Parasitology (62.8%) & 1 Urinalysis (61.6%) sections scored the minimum required point for WHO accreditation. The average score for government laboratories was 78.2 (31.2%) points, of these 6 laboratories were under accreditation process with 106.2 (42.5%) average score, while the private laboratories had 71.2 (28.5%) average score. Of 213 respondents 197 (92.5%) professionals had a knowledge on quality system essentials whereas 155 (72.8%) respondents on accreditation.

Conclusion

Although majority of the laboratory professionals had knowledge on quality system and accreditation, laboratories professionals were not able to practice the quality system properly and most of the laboratories had poor status towards the WHO accreditation process. Thus government as well as stakeholders should integrate accreditation program into planning and health policy.

Sense and nonsense in the process of accreditation of a pathology laboratory

The aim of accreditation of a pathology laboratory is to control and optimize, in a permanent manner, good professional practice in clinical and molecular pathology, as defined by internationally established standards. Accreditation of a pathology laboratory is a key element in fine in increasing recognition of the quality of the analyses performed by a laboratory and in improving the care it provides to patients. One of the accreditation standards applied to clinical chemistry and pathology laboratories in the European Union is the ISO 15189 norm. Continued functioning of a pathology laboratory might in time be determined by whether or not it has succeeded the accreditation process. Necessary requirements for accreditation, according to the ISO 15189 norm, include an operational quality management system and continuous control of the methods used for diagnostic purposes. Given these goals, one would expect that all pathologists would agree on the positive effects of accreditation. Yet, some of the requirements stipulated in the accreditation standards, coming from the bodies that accredit pathology laboratories, and certain normative issues are perceived as arduous and sometimes not adapted to or even useless in daily pathology practice. The aim of this review is to elaborate why it is necessary to obtain accreditation but also why certain requirements for accreditation might be experienced as inappropriate.

Gestational diabetes mellitus prevalence: Effect of the laboratory analytical variation

AIMS

To highlight the effect of laboratory analytic variation, assessed by glucose (a) total analytic laboratory error (TAEL) present in one index laboratory and (b) total recommended allowable error (TAEa) universally applicable to all laboratories, on the prevalence of gestational diabetes mellitus (GDM).

METHODS

2337 pregnant women underwent a 75-g oral glucose tolerance test (OGTT) for universal GDM screening. Since the true value of every laboratory result fluctuates within a range, the glucose TAEL and TAEa were used to define a lower and an upper diagnostic threshold (95% confidence interval, CI) for the three glucose OGTT cut-offs of the criteria of the American Diabetes Association, ADA (2003); the Canadian Diabetes Association, CDA (2013) and the International Association of Diabetes and Pregnancy Study Groups, IADPSG (2010).

RESULTS

For the ADA, CDA and IADPSG criteria, respectively, the GDM prevalence [95% CI, (glucose TAEL) (glucose TAEa)] was 13.3% [(8.0-21.8) (6.3-25.9)], 30% [(17.3-53.1) (14.3-61.3)] and 45.3% [(27.0-71.0) (22.3-79.2)]. Using the lower and higher assigned OGTT glucose thresholds for TAEL, respectively, among the different criteria, either 200 (8.6%)-601 (25.7%) additional or 122 (5.2%)-426 (18.3%) fewer women would be identified with GDM (p<0.0001).

CONCLUSIONS

Independent of the diagnostic criteria, any reported GDM prevalence can potentially vary between one half to two times even for laboratories meeting recommended quality specifications. To avoid misclassifying women with GDM substantially, individual laboratories can significantly reduce this disparity by improving analytic performance. All physicians must ensure that their laboratory meets acceptable quality standards for optimal patient care.

Maintenance of a reliable laboratory service for tuberculosis intervention in Papua New Guinea

The reemergence of tuberculosis, including multidrug-resistant strains, in Papua New Guinea highlights the never ending nature of the antituberculosis (anti-TB) campaign in that country and warrants the need for constant vigilance against the condition. Through surveillance, early detection, and management, the spread and incidence of TB can be kept in check. To maintain successful TB control programs, the government and partners committed to this campaign need to overhaul essential aspects of laboratory services. Clinical laboratories play a critical role in diagnostics; their functions cannot be substituted nor relegated. It is time to end neglect of these services in Papua New Guinea and to arm the laboratories in that country with full financial and logistical support so that they can lead the campaign against TB.

Building capacity in laboratory medicine in Africa by increasing physician involvement: a laboratory medicine course for clinicians

OBJECTIVES

To describe a 4-day laboratory medicine course for clinicians given at Addis Ababa University, Ethiopia, designed to improve the use of laboratory-based diagnoses.

METHODS

Each day was dedicated to one of the following topics: hematology, blood bank/transfusion medicine and coagulation, chemistry, and microbiology. The course included lectures, case-based learning, laboratory tours, and interactive computer case-based homework. The same 12-question knowledge quiz was given before and after the course.

RESULTS

Twenty-eight participants took the quiz before and 21 after completing the course. The average score was 5.28 (range, 2-10) for the initial quiz and 8.09 (range, 4-11) for the second quiz (P = .0001). Two of 12 and 8 of 12 questions were answered correctly by more than 60% of trainees on the initial and second quiz, respectively.

CONCLUSIONS

Knowledge and awareness of the role of the laboratory increased after participation in the course. Understanding of laboratory medicine principles by clinicians will likely improve use of laboratory services and build capacity in Africa.

Piloting laboratory quality system management in six health facilities in Nigeria

Background

Achieving accreditation in laboratories is a challenge in Nigeria like in most African countries. Nigeria adopted the World Health Organization Regional Office for Africa Stepwise Laboratory (Quality) Improvement Process Towards Accreditation (WHO/AFRO– SLIPTA) in 2010. We report on FHI360 effort and progress in piloting WHO-AFRO recognition and accreditation preparedness in six health facility laboratories in five different states of Nigeria.

Method

Laboratory assessments were conducted at baseline, follow up and exit using the WHO/AFRO– SLIPTA checklist. From the total percentage score obtained, the quality status of laboratories were classified using a zero to five star rating, based on the WHO/AFRO quality improvement stepwise approach. Major interventions include advocacy, capacity building, mentorship and quality improvement projects.

Results

At baseline audit, two of the laboratories attained 1- star while the remaining four were at 0- star. At follow up audit one lab was at 1- star, two at 3-star and three at 4-star. At exit audit, four labs were at 4- star, one at 3-star and one at 2-star rating. One laboratory dropped a ‘star’ at exit audit, while others consistently improved. The two weakest elements at baseline; internal audit (4%) and occurrence/incidence management (15%) improved significantly, with an exit score of 76% and 81% respectively. The elements facility and safety was the major strength across board throughout the audit exercise.

Conclusion

This effort resulted in measurable and positive impact on the laboratories. We recommend further improvement towards a formal international accreditation status and scale up of WHO/AFRO– SLIPTA implementation in Nigeria.

The impact of SLMTA in improving laboratory quality systems in the Caribbean Region

Background

Past efforts to improve laboratory quality systems and to achieve accreditation for better patient care in the Caribbean Region have been slow.

Objective

To describe the impact of the Strengthening of Laboratory Management Toward Accreditation (SLMTA) training programme and mentorship amongst five clinical laboratories in the Caribbean after 18 months.

Method

Five national reference laboratories from four countries participated in the SLMTA programme that incorporated classroom teaching and implementation of improvement projects. Mentors were assigned to the laboratories to guide trainees on their improvement projects and to assist in the development of Quality Management Systems (QMS). Audits were conducted at baseline, six months, exit (at 12 months) and post-SLMTA (at 18 months) using the Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA) checklist to measure changes in implementation of the QMS during the period. At the end of each audit, a comprehensive implementation plan was developed in order to address gaps.

Results

Baseline audit scores ranged from 19% to 52%, corresponding to 0 stars on the SLIPTA five-star scale. After 18 months, one laboratory reached four stars, two reached three stars and two reached two stars. There was a corresponding decrease in nonconformities and development of over 100 management and technical standard operating procedures in each of the five laboratories.

Conclusion

The tremendous improvement in these five Caribbean laboratories shows that SLMTA coupled with mentorship is an effective, user-friendly, flexible and customisable approach to the implementation of laboratory QMS. It is recommended that other laboratories in the region consider using the SLMTA training programme as they engage in quality systems improvement and preparation for accreditation.

Translating a National Laboratory Strategic Plan into action through SLMTA in a district hospital laboratory in Botswana

BACKGROUND

The Ministry of Health (MOH) of Botswana adopted Strengthening Laboratory Management Toward Accreditation (SLMTA), a structured quality improvement programme, as a key tool for the implementation of quality management systems in its public health laboratories. Coupled with focused mentorship, this programme aimed to help MOH achieve the goals of the National Laboratory Strategic Plan to provide quality and timely clinical diagnoses.

OBJECTIVES

This article describes the impact of implementing SLMTA in Sekgoma Memorial Hospital Laboratory (SMHL) in Serowe, Botswana.

METHODS

SLMTA implementation in SMHL included trainings, improvement projects, site visits and focused mentorship. To measure progress, audits using the Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA) checklist were conducted at baseline and exit of the programme, with scores corresponding to a zero- to five-star scale. Turnaround times, customer satisfaction, and several other health service indicators were tracked.

RESULTS

The laboratory scored 53% (zero stars) at the baseline audit and 80% (three stars) at exit. Nearly three years later, the laboratory scored 85% (four stars) in an official audit conducted by the African Society for Laboratory Medicine. Turnaround times became shorter after SLMTA implementation, with reductions ranging 19% to 52%; overall patient satisfaction increased from 56% to 73%; and clinician satisfaction increased from 41% to 72%. Improvements in inventory management led to decreases in discarded reagents, reducing losses from US $18 000 in 2011 to $40 in 2013.

CONCLUSION

The SLMTA programme contributed to enhanced performance of the laboratory, which in turn yielded potential positive impacts for patient care at the hospital.

Attaining ISO 15189 accreditation through SLMTA: A journey by Kenya's National HIV Reference Laboratory

Background

The National HIV Reference Laboratory (NHRL) serves as Kenya’s referral HIV laboratory, offering specialised testing and external quality assessment, as well as operating the national HIV serology proficiency scheme. In 2010, the Kenya Ministry of Health established a goal for NHRL to achieve international accreditation.

Objectives

This study chronicles the journey that NHRL took in pursuit of accreditation, along with the challenges and lessons learned.

Methods

NHRL participated in the Strengthening Laboratory Management Toward Accreditation (SLMTA) programme from 2010–2011. Improvement projects were undertaken to address gaps in the 12 quality system essentials through development of work plans, team formation, training and mentorship of personnel. Audits were conducted and the scores used to track progress along a five-star grading scale. Standard quality indicators (turn-around time, specimen rejection rates and service interruptions) were measured. Costs of improvement projects and accreditation were estimated based on expenditures.

Results

NHRL scored 45% (zero stars) at baseline in March 2010 and 95% (five stars) after programme completion in October 2011; in 2013 it became the first public health laboratory in Kenya to attain ISO 15189 accreditation. From 2010–2013, turn-around times decreased by 50% – 95%, specimen rejections decreased by 93% and service interruptions dropped from 15 to zero days. Laboratory expenditures associated with achieving accreditation were approximately US $36 500.

Conclusion

International accreditation is achievable through SLMTA, even for a laboratory with limited initial quality management systems. Key success factors were dedication to a shared goal, leadership commitment, team formation and effective mentorship. Countries wishing to achieve accreditation must ensure adequate funding and support.

Laboratory system strengthening and quality improvement in Ethiopia

Background

In 2010, a National Laboratory Strategic Plan was set forth in Ethiopia to strengthen laboratory quality systems and set the stage for laboratory accreditation. As a result, the Strengthening Laboratory Management Toward Accreditation (SLMTA) programme was initiated in 45 Ethiopian laboratories.

Objectives

This article discusses the implementation of the programme, the findings from the evaluation process and key challenges.

Methods

The 45 laboratories were divided into two consecutive cohorts and staff from each laboratory participated in SLMTA training and improvement projects. The average amount of supportive supervision conducted in the laboratories was 68 hours for cohort I and two hours for cohort II. Baseline and exit audits were conducted in 44 of the laboratories and percent compliance was determined using a checklist with scores divided into zero- to five-star rating levels.

Results

Improvements, ranging from < 1 to 51 percentage points, were noted in 42 laboratories, whilst decreases were recorded in two. The average scores at the baseline and exit audits were 40% and 58% for cohort I (p < 0.01); and 42% and 53% for cohort II (p < 0.01), respectively. The p-value for difference between cohorts was 0.07. At the exit audit, 61% of the first and 48% of the second cohort laboratories achieved an increase in star rating. Poor awareness, lack of harmonisation with other facility activities and the absence of a quality manual were challenges identified.

Conclusion

Improvements resulting from SLMTA implementation are encouraging. Continuous advocacy at all levels of the health system is needed to ensure involvement of stakeholders and integration with other improvement initiatives and routine activities.

Progressing beyond SLMTA: Are internal audits and corrective action the key drivers of quality improvement?

Background

Kenya has implemented the Strengthening Laboratory Management Toward Accreditation (SLMTA) programme to facilitate quality improvement in medical laboratories and to support national accreditation goals. Continuous quality improvement after SLMTA completion is needed to ensure sustainability and continue progress toward accreditation.

Methods

Audits were conducted by qualified, independent auditors to assess the performance of five enrolled laboratories using the Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA) checklist. End-of-programme (exit) and one year post-programme (surveillance) audits were compared for overall score, star level (from zero to five, based on scores) and scores for each of the 12 Quality System Essential (QSE) areas that make up the SLIPTA checklist.

Results

All laboratories improved from exit to surveillance audit (median improvement 38 percentage points, range 5–45 percentage points). Two laboratories improved from zero to one star, two improved from zero to three stars and one laboratory improved from three to four stars. The lowest median QSE scores at exit were: internal audit; corrective action; and occurrence management and process improvement (< 20%). Each of the 12 QSEs improved substantially at surveillance audit, with the greatest improvement in client management and customer service, internal audit and information management (≥ 50 percentage points). The two laboratories with the greatest overall improvement focused heavily on the internal audit and corrective action QSEs.

Conclusion

Whilst all laboratories improved from exit to surveillance audit, those that focused on the internal audit and corrective action QSEs improved substantially more than those that did not; internal audits and corrective actions may have acted as catalysts, leading to improvements in other QSEs. Systematic identification of core areas and best practices to address them is a critical step toward strengthening public medical laboratories.

Building local human resources to implement SLMTA with limited donor funding: The Ghana experience

BACKGROUND

In 2009, Ghana adopted the Strengthening Laboratory Management Toward Accreditation (SLMTA) programme in order to improve laboratory quality. The programme was implemented successfully with limited donor funding and local human resources.

OBJECTIVES

To demonstrate how Ghana, which received very limited PEPFAR funding, was able to achieve marked quality improvement using local human resources.

METHOD

Local partners led the SLMTA implementation and local mentors were embedded in each laboratory. An in-country training-of-trainers workshop was conducted in order to increase the pool of local SLMTA implementers. Three laboratory cohorts were enrolled in SLMTA in 2011, 2012 and 2013. Participants from each cohort attended in a series of three workshops interspersed with improvement projects and mentorship. Supplemental training on internal audit was provided. Baseline, exit and follow-up audits were conducted using the Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA) checklist. In November 2013, four laboratories underwent official SLIPTA audits by the African Society for Laboratory Medicine (ASLM).

RESULTS

The local SLMTA team successfully implemented three cohorts of SLMTA in 15 laboratories. Seven out of the nine laboratories that underwent follow-up audits have reached at least one star. Three out of the four laboratories that underwent official ASLM audits were awarded four stars. Patient satisfaction increased from 25% to 70% and sample rejection rates decreased from 32% to 10%. On average, $40 000 was spent per laboratory to cover mentors' salaries, SLMTA training and improvement project support.

CONCLUSION

Building in-country capacity through local partners is a sustainable model for improving service quality in resource-constrained countries such as Ghana. Such models promote country ownership, capacity building and the use of local human resources for the expansion of SLMTA.

The SLMTA programme: Transforming the laboratory landscape in developing countries

Background

Efficient and reliable laboratory services are essential to effective and well-functioning health systems. Laboratory managers play a critical role in ensuring the quality and timeliness of these services. However, few laboratory management programmes focus on the competencies required for the daily operations of a laboratory in resource-limited settings. This report provides a detailed description of an innovative laboratory management training tool called Strengthening Laboratory Management Toward Accreditation (SLMTA) and highlights some challenges, achievements and lessons learned during the first five years of implementation (2009–2013) in developing countries.

Programme

SLMTA is a competency-based programme that uses a series of short courses and work-based learning projects to effect immediate and measurable laboratory improvement, while empowering laboratory managers to implement practical quality management systems to ensure better patient care. A SLMTA training programme spans from 12 to 18 months; after each workshop, participants implement improvement projects supported by regular supervisory visits or on-site mentoring. In order to assess strengths, weaknesses and progress made by the laboratory, audits are conducted using the World Health Organization’s Regional Office for Africa (WHO AFRO) Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA) checklist, which is based on International Organization for Standardization (ISO) 15189 requirements. These internal audits are conducted at the beginning and end of the SLMTA training programme.

Conclusion

Within five years, SLMTA had been implemented in 617 laboratories in 47 countries, transforming the laboratory landscape in developing countries. To our knowledge, SLMTA is the first programme that makes an explicit connection between the performance of specific management behaviours and routines and ISO 15189 requirements. Because of this close relationship, SLMTA is uniquely positioned to help laboratories seek accreditation to ISO 15189.

Medical laboratories in sub-Saharan Africa that meet international quality standards

OBJECTIVES

A recent survey of laboratories in Kampala, Uganda, demonstrated that only 0.3% of laboratories (3/954) met international quality standards. To benchmark laboratory quality throughout the rest of sub-Saharan Africa (SSA), we compiled a list of SSA laboratories meeting international quality standards.

METHODS

Accrediting bodies were queried via online registries or direct communication in May 2013.

RESULTS

There were 380 laboratories accredited to international standards in SSA. Ninety-one percent were in South Africa. Thirty-seven of 49 countries had no laboratories accredited to international quality standards. Accredited laboratory density (per million people) in South Africa, Namibia, and Botswana were similar to those in many European countries. Single variable linear regression showed a correlation between accredited laboratory density and health expenditures per person (adjusted R(2) = 0.81, P < .001).

CONCLUSIONS

Most SSA countries do not have an accredited clinical laboratory. For those that do, there is a strong correlation between country-specific accredited laboratory density and per-capita health expenditures.

Impact of proficiency testing program for laboratories conducting early diagnosis of HIV-1 infection in infants in low- to middle-income countries

A voluntary, cost-free external quality assessment (EQA) program established by the U.S. Centers for Disease Control and Prevention (CDC) was implemented to primarily monitor the performance of laboratories conducting HIV Early Infant Diagnosis (EID) from dried blood spots (DBS) in low- to middle-income countries since 2006. Ten blind DBS proficiency test (PT) specimens and 100 known HIV-positive and -negative DBS specimens (to be used as internal controls) were shipped triannually to participating laboratories with reports for the PT specimens due within 30 days. The participant's results and a summary of the performance of all participating laboratories and each diagnostic method were provided after each test cycle. Enrollment in the CDC PT program expanded progressively from 17 laboratories from 11 countries in 2006 to include 136 laboratories from 41 countries at the end of 2012. Despite external pressures to test and treat more children while expanding EID programs, mean PT test scores significantly improved over time as demonstrated by the upward trend from mid-2006 to the end of 2012 (P=0.001) and the increase in the percentage of laboratories scoring 100% (P=0.003). The mean test scores plateaued over the past 10 testing cycles, ranging between 98.2% and 99.7%, and discordant test results still occur but at a rate of no higher than 2.6%. Analysis of these test results suggests a positive impact of proficiency testing on the testing performance of the participating laboratories, and a continuous training program and proficiency testing participation may translate into laboratories improving their testing accuracy.
