| Abstract | PURPOSE/OBJECTIVE: The purpose of this study was to test an evidence-based procedure of drawing blood samples for coagulation testing from heparinized peripherally inserted central catheter (PICC) by comparing results with blood drawn from venipuncture (VP). DESIGN: A prospective, quasi-experimental design using purposive sampling was used. SETTING: The setting was a 230-bed community hospital located in the Southwest. The hospital is part of a 15-hospital system. SAMPLE: : The sample was composed of 30 hospitalized patients with heparinized PICCs. METHODS: Informed consent was obtained. Using aseptic technique, samples of blood were drawn via VP and from the PICC using the evidence-based procedure. Data were analyzed using Pearson product moment correlations and Bland-Altman analysis. FINDINGS: For 5 coagulation tests studied, correlations between PICC values and VP values ranged from 0.990 to 0.998, indicating almost perfect correlations. In Bland-Altman analyses, mean biases and SDs were small to moderate for prothrombin time, 0.13 seconds (-0.55 to 0.81 seconds) (P = 0.0484); international normalized ratio, 0.010 (-0.050 to 0.070) (P = 0.085); partial thromboplastin time, 2.16 seconds (-5.10 to 9.43 seconds) (P = 0.0033); and fibrinogen, -18.2 mg (-70.4 to 34.1 mg) (P = 0.0033) and 0.52 (-0.73 to 1.77) seconds (P = 0.0003). Correlations of absolute difference versus average ranged from 0.18 to 0.49. Only the paired international normalized ratio samples had P values suggesting nonagreement. CONCLUSIONS: Drawing blood samples from heparinized PICCs for coagulation tests using the evidence-based procedure developed for this study resulted in accurate coagulation test results in 4 of the 5 tests: prothrombin time, partial thromboplastin time, and fibrinogen in seconds and in milligrams. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
