RESUMEN
In the inpatient setting, antibiotics are generally administered via bedside pumps with multiple daily dosing. Utilisation of a continuous antibiotic infusion (CAI) instead might have patient and nursing satisfaction, workflow efficiencies and infection control benefits. We aimed to study the utilisation of CAI in the inpatient setting for routine antibiotic administration. Patients receiving a peripherally inserted central venous catheter (PICC) for antibiotic administration were screened for the study. The patients were randomised to either (1) standard pump and intermittent antibiotic administration (IAA) or (2) CAI via an ambulatory pump. An accelerometer placed on the ankle was used to assess patient activity. Nursing and patient satisfaction surveys were also carried out. Forty patients met the study criteria for enrolment with 21 patients being enrolled in the CAI arm of the study. One hundred and five days of accelerometer recordings were available for analysis. The geometric mean activity was 45 min/day in the standard arm and 64 min/day in the CAI arm. This represented a 42% (95% CI: -14 to 133%, p = 0.16) difference in activity between the two groups. Nursing staff reported that they spent less time throughout their shift attending the antibiotic line or pump in patients who were in the CAI arm of the study (p < 0.001). In addition, patients in this arm of the study were more likely to recommend this method of administration of antibiotics to a family member (p =0.0001). The MOBILISE study showed nursing and patient satisfaction when CAI were utilised in the inpatient setting. A statistically non-significant difference in mobility was seen. The trial was registered (28/03/2018) with the Australia New Zealand Clinical Trials Registry (ACTRN12618000452291).

High levels of sedentary time have been detrimentally linked to health outcomes. Differentiating sitting from lying may help to further understand the mechanisms associated with these health impacts. This study compares the inter-method agreement between the "single-monitor" method (thigh-worn activPAL3TM ) and a more robustly validated "dual-monitor" method (trunk and thigh-worn activPAL3TM ) in their classifications of sitting and lying under free-living conditions. Thirty-five participants (20-50 years) wore two activity monitors (thigh and trunk) for 24 hours. Total time spent lying and sitting was calculated for both methods, and agreement was determined using ICC and Bland-Altman methods. As there was no gold standard, further data were collected from five participants during structured activities that were designed to challenge classification, to better understand any disagreement between the methods. ICCs were 0.81 for sitting time and 0.64 for lying time. The single-monitor method detected less lying time than the dual-monitor method, with a mean difference of -25 minutes (95% agreement limits: -172 to 221 minutes), including three cases with extreme disagreement (mostly in daytime lying classification). The additional data collection suggested a major source of disagreement was failure of the single-monitor method to identify lying that involved no rotation around the longitudinal axis. In conclusion, there was some agreement between the single- and dual-monitor estimates of lying time under free-living conditions, but measures were not interchangeable. The main disagreement was in how the methods classified daytime lying and lying tasks involving no lateral movement. Both methods yield promise for measuring time in bed.
