Timely delivery of laboratory efficiency information, Part I: Developing an interactive turnaround time dashboard at a high-volume laboratory

BACKGROUND

Mean turn-around time (TAT) reporting for testing laboratories in a national network is typically static and not immediately available for meaningful corrective action and does not allow for test-by-test or site-by-site interrogation of individual laboratory performance.

OBJECTIVE

The aim of this study was to develop an easy-to-use, visual dashboard to report interactive graphical TAT data to provide a weekly snapshot of TAT efficiency.

METHODS

An interactive dashboard was developed by staff from the National Priority Programme and Central Data Warehouse of the National Health Laboratory Service, Johannesburg, South Africa, during 2018. Steps required to develop the dashboard were summarised in a flowchart. To illustrate the dashboard, one week of data from a busy laboratory for a specific set of tests was analysed using annual performance plan TAT cut-offs. Data were extracted and prepared to deliver an aggregate extract, with statistical measures provided, including test volumes, global percentage of tests that were within TAT cut-offs and percentile statistics.

RESULTS

Nine steps were used to develop the dashboard iteratively with continuous feedback for each step. The data warehouse environment conformed and stored laboratory information system data in two formats: (1) fact and (2) dimension. Queries were developed to generate an aggregate TAT data extract to create the dashboard. The dashboard successfully delivered weekly TAT reports.

CONCLUSION

Implementation of a TAT dashboard can successfully enable the delivery of near real-time information and provide a weekly snapshot of efficiency in the form of TAT performance to identify and quantitate bottlenecks in service delivery.

A comprehensive review of the SLMTA literature part 2: Measuring success

Background

Since its introduction in 2009, the Strengthening Laboratory Management Toward Accreditation (SLMTA) programme has been implemented in 617 laboratories in 47 countries.

Objective

We completed a systematic review of the published literature on SLMTA. The review consists of two companion papers; this article examines quantitative evidence presented in the publications along with a meta-analysis of selected results.

Methods

We identified 28 published articles with data from SLMTA implementation. The SLMTA programme was evaluated through audits based on a standard checklist, which is divided into 12 sections corresponding to the 12 Quality System Essentials (QSEs). Several basic service delivery indicators reported by programmes were also examined. Results for various components of the programme were reviewed and summarised; a meta-analysis of QSE results grouped by the three stages of the quality cycle was conducted for 126 laboratories in 12 countries.

Results

Global programme data show improved quality in SLMTA laboratories in every country, with average improvements on audit scores of 25 percentage points. Meta-analysis identified Improvement Management as the weakest stage, with internal audit (8%) and occurrence management (16%) showing the lowest scores. Studies documented 19% – 95% reductions in turn-around times, 69% – 93% reductions in specimen rejection rates, 76% – 81% increases in clinician satisfaction rates, 67% – 85% improvements in external quality assessment results, 50% – 66% decreases in nonconformities and 67% increases in staff punctuality.

Conclusions

The wide array of results reported provides a comprehensive picture of the SLMTA programme overall, suggesting a substantive impact on provision of quality laboratory services and patient care. These comprehensive results establish a solid data-driven foundation for program improvement and further expansion.

A comprehensive review of the SLMTA literature part 1: Content analysis and future priorities

Background

Since its introduction in 2009, the Strengthening Laboratory Management Toward Accreditation (SLMTA) programme has been implemented widely throughout Africa, as well as in the Caribbean, Central and South America, and Southeast Asia.

Objective

We compiled results from local, national and global studies to provide a broad view of the programme and identify directions for the future. The review consists of two companion papers; this paper focuses on content analysis, examining various thematic components of the SLMTA programme and future priorities.

Methods

A systematic literature search identified 28 published articles about implementing the SLMTA programme. Results for various components of the SLMTA programme were reviewed and summarised.

Results

Local and national studies provide substantial information on previous experiences with quality management systems; variations on SLMTA implementation; building human resource capacity for trainers, mentors and auditors; the benefits and effectiveness of various types of mentorship; the importance of management buy-in to ensure country ownership; the need to instill a culture of quality in the laboratory; success factors and challenges; and future directions for the programme.

Conclusions

Local, national and global results suggest that the SLMTA programme has been overwhelmingly successful in transforming laboratory quality management. There is an urgent need to move forward in four strategic directions: progression (continued improvement in SLMTA laboratories), saturation (additional laboratories within countries that have implemented SLMTA), expansion (implementation in additional countries), and extension (adapting SLMTA for implementation beyond the laboratory), to lead to transformation of overall health systems and patient care.
