Sustained Quality and Service Delivery in an Expanding Point-of-Care Testing Network in Remote Australian Primary Health Care.

CONTEXT.­: Since 2008, the Northern Territory Point-of-Care Testing Program has improved patient access to pathology testing for acute and chronic disease management for remote health services. OBJECTIVE.­: To evaluate the analytical quality, service delivery, and clinical utility of an expanding remote point-of-care testing network. DESIGN.­: Four years (2016-2019) of data on analytical quality, test numbers, and training statistics and 6 months of clinical point-of-care testing data from Abbott i-STATs at remote health services throughout the Northern Territory were analyzed to assess analytical performance, program growth, and clinical utility. RESULTS.­: From 2016 to 2019, point-of-care test numbers increased, with chemistry and blood gas testing more than doubling to 8500 and 6000 tests, respectively, troponin I testing almost doubling (to 6000), and international normalized ratio testing plateauing at 8000 tests. Participation in quality control and proficiency testing was high, with quality comparable to laboratory-based analytical goals. A shift toward flexible training and communication modes was noted. An audit of point-of-care test results demonstrated elevated creatinine, associated with chronic kidney disease management, as the most common clinically actionable patient result. CONCLUSIONS.­: The Northern Territory Point-of-Care Testing Program provides high quality point-of-care testing within remote primary health services for acute and chronic patient management and care. Clinical need, sound analytical performance, flexibility in training provision, and effective support services have facilitated the sustainability of this expanding point-of-care testing model in the remote Northern Territory during the past 11 years.

Design, implementation and initial assessment of the Northern Territory Point-of-Care Testing Program.

OBJECTIVE: The objective of the study was to improve pathology services in selected remote health centres from the Northern Territory (NT) through the implementation of a quality managed point-of-care pathology testing (POCT) service. DESIGN: Study of the efficacy of the POCT service after 1 year and qualitative survey of POCT device operators. SETTING: The study was set in thirty-three remote health centres in the NT administered by the NT Department of Health. PARTICIPANTS: Remote health centre staff at participating remote health centres participated in the study. INTERVENTIONS: The introduction of the i-STAT device to perform on-site POCT. MAIN OUTCOME MEASURES: The main outcome measures used in the study were the number of remote staff trained, volume of testing performed and satisfaction of POCT device operators. RESULTS: One hundred and sixty-four health professional staff were trained to perform i-STAT POCT during the first year of the program. A total of 2290 POCT tests were performed on the i-STAT. The volume of testing consistently increased across the year. Tests for international normalised ratio were the most frequently performed (averaging 70 tests per month). Stakeholder satisfaction with the i-STAT device was high, with a statistically significant improvement in satisfaction levels with pathology service provision being reported after the introduction of POCT. Greater than 80% of respondents stated POCT was more convenient than the laboratory service and assisted in the stabilisation of acutely ill patients. CONCLUSIONS: The NT POCT Program has been operationally effective and well received by staff working as i-STAT POCT operators in remote health centres. Retention of remote health centre staff is the most significant challenge to ensuring the program's long-term viability.
