Early availability of laboratory results increases same day ward discharge rates.

BACKGROUND: Delayed discharge reduces hospital efficiency and inconveniences patients. Most hospitals discharge in the afternoon, whereas the most common admission time is mid-morning. Consequently, new patients wait for the beds of patients who are fit to be discharged. Earlier discharge may, therefore, improve patient flow. We investigated the impact of early phlebotomy with early availability of laboratory results on patient discharge rates and discharge time. METHODS: Discharge rates, discharge time and sample turnaround time were assessed before (1 October 2014 to 31 December 2014) and after (1 October 2015 to 31 December 2015) introduction of earlier phlebotomy with availability of laboratory results prior to the ward rounds on two surgical wards. RESULTS: Following the intervention, over 95% of results were available before 8:30 am in 2015 as compared to less than 1% in 2014. Specimen turnaround times were similar in both study periods. Even after adjustment for age, gender, admission type and length of admission, the same day discharge rate was higher in 2015 compared to 2014 (60% vs. 52%; p<0.002), but time of discharge was unchanged. CONCLUSIONS: Early availability of blood results prior to ward rounds increased ward discharges but did not affect discharge time.

An automated minimum retest interval rejection rule reduces repeat CRP workload and expenditure, and influences clinician-requesting behaviour.

AIMS: Repeat serum C-reactive protein (CRP) measurements on the same day or on consecutive days are of limited clinical value. Minimum retesting intervals are recommended for managing unnecessary repeat testing. As not previously reported, we studied the effect of minimum retesting interval test rejection on laboratory workload and expenditure and on clinician-requesting behaviour. METHODS: In a prospective study, we evaluated the effect of an automated 48 h CRP minimum retesting interval rule on inpatient and outpatient CRP workload and costs. Control data on inpatient and outpatient serum urea and electrolytes (UE) workload were collected during the study. RESULTS: Over 1 year, there was a 7.0% and 12.3% decrease in CRP requests and CRP tests analysed, respectively, following the introduction of the minimum retesting interval rule when compared to the 1 year baseline period. This equated to an estimated annual reduction in revenue costs of £10 500, but cash savings in consumable costs of £3000. There was no significant change in UE requests. CONCLUSIONS: We report, for the first time, that automated minimum retesting interval rejection rules as a stand-alone strategy are a cheap and sustainable method for reducing unnecessary repeat CRP tests, resulting in small laboratory cash savings, more efficient use of laboratory resources and standardisation of patient care pathways. The minimum retesting interval rejection rule also altered clinician test-requesting behaviour towards more appropriate requesting.
