Despite the urgent need for POCTs, deploying them in resource limited settings can be fraught with difficulty. "POCTs are developed by researchers and engineers and implemented by a separate group of public health professionals at a local level. There are so many variables that can make or break the effectiveness of any test, and so often the scientists and engineers developing the test are not aware of them." said Keith Klugman, who chaired the colloquium. "POCTs that perform well in testing may not function 'on the ground' in resource limited areas, where there may not be running water, electricity, or trained personnel to administer the test."
Recognizing the need to connect the scientists and engineers developing the POCTs with the health care workers implementing them, the American Academy of Microbiology convened a colloquium in Sept. 2011 to discuss how to develop POCTs that can be effectively integrated into resource limited settings. The participants discussed which tests were needed most urgently, features that should be incorporated in the design of the test to make it more effective in the field, and how collaborations between communities could foster an environment of success for new POCTs.
The resulting report makes recommendations in several areas. It details a list of POCTs that would make the biggest impact, for example, tests to detect drug resistance, or effectively monitor viral load in HIV patients. The report describes qualities needed in tests to be effective in resource limited settings such as minimal power requirements, simple interfaces, and integrated instructions on use and quality control protocols. Finally, it recommends changes in how POCTs are regulated, approved and brought to market to help foster a more conducive environment for POCT development.
"POCTs can fundamentally change the quality of health care received in resource limited settings, but only if scientists, engineers, and health care professionals work together to develop simple, effective POCTs," said Jeanne Jordan of George Washington University, one of the colloquium participants. "Bringing the Lab to the Patient: Developing Point-of Care Diagnostics for Resource Limited Settings" is a step forward in forming productive collaborations between these groups to bring POCTs to the people that need them the most.
