Early reattenders to the paediatric emergency department: A prospective cohort study and multivariate analysis.

AIMS: The rate of unplanned reattendances is used as an indicator of the quality of care delivered in a paediatric emergency department (PED). With early reattendance in the UK well above the national target of 1-5%, we aimed to identify the factors which predict unplanned early reattendance to the PED. METHODS: This is a prospective, single-centre cohort study undertaken over 12 months. Data were collected on all patients who reattended the PED within 7 days of their initial visit as well as for a comparative cohort of patients with no visit in the preceding or subsequent 7 days. Multiple patient and departmental variables were recorded and analysed using a multivariate regression model. RESULTS: There were a total of 19 420 index visits to the PED, of which 1461 patients had an unscheduled reattendance within 7 days - a rate of 7.5%. Factors associated with unplanned but related reattendance include young age and diagnosis with a respiratory or other medical illness. Interestingly, the grade of clinician appeared to be relevant with patients seen by junior members of the medical team less likely to reattend. Acuity of illness was not a significant factor. A substantial number of unplanned early reattenders (36.3%) would have been missed had a time period of 72 h been used rather than 7 days. CONCLUSIONS: This study identifies the typical patient who will have an unplanned, related early reattendance to a PED. This study also supports the use of a 7-day time period when using early reattendance as a performance indicator.

Intraoperative Vasopressor Usage in Free Tissue Transfer: Should We Be Worried?

BACKGROUND: The role of vasopressors has long been a subject of debate in microsurgery. Conventional wisdom dictates the avoidance of vasopressor use, due to concerns such as peripheral vasoconstriction, inducing vasospasm of the anastomoses, and leading to failure in perfusion. It has since become common practice in some centers to avoid intraoperative vasopressor use during free tissue transfer surgery. Recent studies have suggested that this traditional view may not be supported by clinical evidence. However, none of these studies have separated vasopressor use by method of administration. METHODS: We conducted a retrospective review of our experience of vasopressor use in free flap surgery at a single high-volume center. The outcome measures were flap failure, flap-related complications and overall postoperative complications (reported using the Clavien-Dindo classification). Groups were compared using Chi-square or Fisher's Exact test where appropriate. RESULTS: A total of 777 cases in 717 patients were identified. 59.1% of these had vasopressors administered intraoperatively. The overall failure rate was 2.2%, with 9.8% experienced flap-related complications. There was no difference in flap loss when vasopressors were administered, but an increased rate of microvascular thrombosis was noted (p = 0.003). Continuous administration of vasopressors was associated with reduced venous congestion, whereas intermittent boluses increased risk of microvascular thrombosis. CONCLUSION: Our study confirms previous findings that intraoperative vasopressor use in free flap surgery is not associated with increased failure rate. Administering vasopressors continuously may be safer than via repeated boluses.
