Pharmaceutical Analysis of Peripherally Inserted Central Catheter Requests Increases the Use of Single-Lumen Catheters: A Prospective Pilot Study.

Objectives: Several studies have suggested a strong relationship between the number of peripherally inserted central catheter (PICC) lumens and the risk of complications. The purpose of this study is to evaluate the impact of the intervention of a clinical pharmacist (CP) on the number of lumens of PICC inserted and assess PICC-related complications.

Method: This prospective monocentric study included all consecutive patients from 5 different units who underwent PICC insertions from September 2017 to March 2018. In the intervention group, the CP validated the pertinence of each PICC request according to the patients' records, choice of device (single or double lumen), and incompatibilities between treatments. The control group consisted of patients who underwent PICC insertions without a CP intervention. Complications were prospectively recorded up to PICC removal. Multivariate analyses adjusted for sex, age, and PICC line duration were performed.

Results: In the intervention group, 207 PICCs were inserted, 81.2% (n = 168) were single-lumen devices and 18.8% (n = 39) were double-lumen devices. In the control group (n = 77), the use of single-lumen PICCs was significantly lower (n = 48, 62.3%; P = 0.002). After intervention, the overall complication incidence rate decreased from 4.42 to 3.23 per 1000 catheter days ( P = 0.082). Considering the overall population, 216 single-lumen PICCs were inserted with significantly fewer complications than double-lumens (respectively n = 16, 16/216 = 7.4%, versus n = 15, 15/68 = 22.1%, P = 0.002). The adjusted odds ratio of double-lumen PICC was 3.83 (95% confidence interval, 1.46-10.07; P = 0.007).

Conclusions: Our study showed the intervention of a CP in the PICC insertion process could increase the use of single-lumen PICCs and tended to reduce associated complications.
