Risk reduction in pleural procedures: sonography, simulation and supervision.

PURPOSE OF REVIEW: Complications from pleural drainage procedures are common, but their incidence is often underrecognized. Significant morbidity and mortality can arise, particularly as a result of poor procedural technique, lack of training and inadequate supervision. This review discusses safety considerations of common pleural procedures, methods for risk minimization and training issues. RECENT FINDINGS: Recent data have identified deaths and significant adverse events associated with pleural drainage procedures. Evidence suggests that significant risk reduction might be achieved by restricting the number of physicians authorized to perform a pleural aspiration to a smaller expert group who have had specific training and regularly perform the procedure. Pleural ultrasound has been shown to increase the accuracy of fluid localization and decrease the risk of postprocedure pneumothorax. SUMMARY: Strategies to improve physician training, reduce unnecessary pleural procedures and improve site selection (using pleural ultrasound) may reduce complication rates. Consequently, several international authorities have recently published updated guidelines and educational packages aimed at improving the safety of pleural intervention. Pleural ultrasound has the potential to significantly decrease adverse event rates, but requires specific training and has several possible pitfalls.

Pseudo-tumor mimicking indwelling pleural catheter tract metastasis in mesothelioma.

Patients with malignant mesothelioma are known to be at risk of developing needle tract metastasis from seeding of malignant cells at the pleural intervention site. Histologic confirmation of needle tract metastases is seldom sought. The diagnosis and management (often radiotherapy) are almost always based on clinical judgment of new subcutaneous lesions at prior pleural puncture sites in mesothelioma patients. We report 2 patients with mesothelioma who developed new subcutaneous nodules at their indwelling pleural catheter insertion site, mimicking tract metastases. Biopsies of both lesions revealed benign etiologies and both resolved without requiring irradiation. These cases remind clinicians that new subcutaneous lesions can be benign even when arising at pleural puncture sites of malignant pleural mesothelioma patients. Percutaneous biopsy can clarify the diagnosis in suitable cases.

Improved stroke care processes and outcomes following the institution of an acute stroke unit at a New Zealand district general hospital.

AIMS: To examine whether stroke care processes and outcomes are improved following the institution of an acute stroke unit (ASU) at a medium-sized New Zealand hospital. METHODS: Two retrospective audits over 12-month periods were carried out at Hutt Valley Hospital before and after the institution of a 6-bed ASU. Data was collected on demographics, length of stay, stroke type, investigations, processes of care and outcomes. RESULTS: 139 strokes pre ASU and 155 strokes post ASU were studied. 86.8% of strokes received stroke unit care in the 2009 audit. There were more intracerebral haemorrhages in 2006 (17.2% vs. 9.0%). Significant improvements were seen between 2006 and 2009 in time to aspirin administration (52.7 versus 14.5 hours), swallow assessment within 24 hours (88.5% versus 96.1%), lag time to carotid Doppler studies (21 days versus 4.5 days), pressure risk assessments (19.6%, versus 87.2%) and urinary infection rates (10.8% versus 2.0% ). Total length of stay (TLOS) and mortality were reduced but the difference was not statistically significant. (20.5 days versus 18.3 days p=0.34, Inpatient mortality 16.2% versus 10% p=0.12). CONCLUSIONS: The introduction of an ASU has resulted in improvements in several key processes of stroke care. Overall mortality and total length of stay showed a trend to improvement after the establishment of an ASU.
