Successful implementation of a performance-related audit tool for sonographers.

A robust, sustainable audit programme for diagnostic ultrasound is hard to implement and establish. It requires time and resources to develop and to be relevant to clinical practice. There is a need for all ultrasound practitioners to undertake continuing professional development that underpins their roles and responsibilities within the workplace. A project group was established to evaluate how sonographers undertake Continuing Professional Development, with a view to understanding if implementing a performance-related audit process could support Continuing Professional Development. The group reviewed their clinical practice with an aim of developing a clinical governance and audit programme that could support both the needs of the service and sonographers alike. Our project has demonstrated that the implementation of this audit and case review process has positively contributed to our service and provided a more transparent and tangible account of sonographer performance.

Usage of prophylactic radiologically inserted gastrostomy in head and neck cancer patients.

AIM: To assess outcomes and usage rate of prophylactic radiologically inserted gastrostomy (RIG) in head and neck cancer (HNC) patients. MATERIALS AND METHODS: Outcome data of all HNC patients who underwent prophylactic RIG over a 22-month period (November 2007 to September 2009) in a tertiary referral centre were collected retrospectively. Thirty-day mortality, major and minor complication rates, and subsequent usage of the RIG were analysed. RESULTS: Fifty-one HNC patients underwent prophylactic RIG. Three minor and no major immediate complications were identified. Sixteen minor and three major complications at 30-days were identified. Three (5.9%) major complications were identified. There was one death due to disease progression and not RIG insertion. The RIG was not used in 17.7% of patients post-procedure. CONCLUSION: Prophylactic RIG in HNC patients has a comparable mortality rate to RIG insertion in HNC patients with mixed indications. However, the number of cases where the gastrostomy is not used raises important concerns and warrants further investigation.

Cytological sampling versus forceps biopsy during percutaneous transhepatic biliary drainage and analysis of factors predicting success.

PURPOSE: To assess the accuracy of cytological sampling and forceps biopsy in obstructing biliary lesions and to identify factors predictive of success. METHODS: Consecutive patients (n = 119) with suspected malignant inoperable obstructive jaundice treated with percutaneous transhepatic biliary drainage during 7 years were included (60 male; mean age 72.5 years). All patients underwent forceps biopsy plus cytological sampling by washing the forceps device in cytological solution. Patient history, procedural and pathological records, and clinical follow-up were reviewed. Statistical analysis included chi-square test and multivariate regression analysis. RESULTS: Histological diagnosis after forceps biopsy was more successful than cytology: Sensitivity was 78 versus 61%, and negative predictive value was 30 versus 19%. Cytology results were never positive when the forceps biopsy was negative. The cytological sample was negative and forceps sample positive in 2 cases of cholangiocarcinoma, 16 cases of pancreatic carcinoma, and 1 case of benign disease. Diagnostic accuracy was predicted by low bilirubin (p < 0.001), aspartate transaminase (p < 0.05), and white cell count (p ≤ 0.05). CONCLUSIONS: This technique is safe and effective and is recommended for histological diagnosis during PTBD in patients with inoperable malignant biliary strictures. Diagnostic yield is greater when bilirubin levels are low and there is no sepsis; histological diagnosis by way of forceps biopsy renders cytological sampling unnecessary.

Percutaneous transhepatic biliary drainage (PTBD) with or without stenting-complications, re-stent rate and a new risk stratification score.

OBJECTIVES: To review the success rate and number of complications in patients with obstructive jaundice treated with percutaneous transhepatic biliary drainage (PTBD), and to stratify the procedural risk of both PTBD and biliary stenting. SUBJECTS AND METHODS: 948 procedures performed in 704 consecutive patients with obstructive jaundice over a 7 year period were reviewed: 345 male; 359 females, mean age 70.1 years (range 48-96 years). Statistical analysis included X ( 2 ) test and multivariate logistic regression analysis. RESULTS: The technical success rate was 99%. The mortality related to the procedure was 2% and the 30-day mortality 13%. 91 (13%) stents inserted occluded during the study period. Predictors for stent failure and re-stenting were a diagnosis of cholangiocarcinoma, a lesion in the distal CBD, a high bilirubin, high urea and high white cell count and post procedure cholangitis. Factors significantly related to complications and 30-day mortality were retrospectively reviewed to devise a risk stratification score. CONCLUSIONS: PTBD and stenting offer a safe and effective method in providing palliative treatment for patients with biliary obstruction. Patients likely to have high levels of morbidity and mortality can be predicted before PTBD, using a risk stratification score, highlighting the need for closer clinical observation and delayed stent placement.
