Follow-up after four-year quality improvement program to prevent inferior limb deep vein thrombosis in intensive care unit.

INTRODUCTION: Deep vein thrombosis (DVT) is a life-threatening complication in intensive care unit (ICU) patients and DVT incidence is used as a marker of quality care. In our ICU an educational program for implementation of DVT prophylaxis and ultrasound screening resulted in a remarkable decrease in DVT incidence which fell from 11.6% to 4.7%. The aim of this paper is to investigate a 4-year long persistent quality improvement of DVT prophylaxis obtained through the implementation of our educational intervention. METHODS: The study was composed of three phases: after the first retrospective investigation of DVT incidence and the evidence of the efficacy of the educational program, this third phase investigates the 2-year long sustainability and persistence in the fall of DVT incidence by the adoption of 1) an electronic form for DVT prophylaxis prescription, 2) a nursing protocol for the application of elastic stokes and 3) a personalized form with a check-list dedicated to DVT prophylaxis. Ultrasound DVT screening was performed twice a week by ICU clinicians. RESULTS: The application of DVT prophylaxis was associated with a very low incidence of DVT (2.6%) not entirely attributable to changes in characteristics of enrolled patients and/or to less intensive DVT ultrasound screening when compared to the preceding phases. Mean mechanical ventilation duration and ICU length of stay were short and similar to those of the second phase and ICU mortality did not change. CONCLUSIONS: The direct involvement of ICU clinicians and nurses in the application of DVT prophylaxis and in DVT diagnosis markedly contributed to maintain a low DVT incidence over time, despite the high turnover of patients.

Implantation of 3951 long-term central venous catheters: performances, risk analysis, and patient comfort after ultrasound-guidance introduction.

BACKGROUND: Despite evidence demonstrating improved safety with ultrasound-guided placement of central venous catheters (CVC) in comparison with the use of anatomical landmarks, ultrasound guidance is still not routinely used by all physicians when obtaining central venous access. METHODS: We report data pertaining to the placement of long-term CVCs in a 7-year period before and after ultrasound guidance was introduced. We included 3951 procedures (total of 1,642,402 catheter days) in our study: 1584 using the anatomical landmark method (landmark group, January 2000 to May 2003), and 2367 with ultrasound guidance (ultrasound group, June 2003 to May 2007). All procedures were performed by the same team of intensivists. Comparison criteria included procedural data, complications, patient's comfort, and perceptions. Variables were analyzed with Student's t test and χ(2) test. Multivariate analysis was performed according to the Cox proportional hazards regression model. RESULTS: Using ultrasound guidance, we noted a significant reduction in procedure time in both port (mean difference 4.9 ± 0.4 minutes, confidence interval [CI] 4.1 to 5.7) and tunneled catheter (mean difference 2.4 ± 0.8 minutes, CI 0.9 to 3.8) placement. The landmark method was associated with an increased risk of overall perioperative complications (4.5, CI 3.6 to 5.6). Among disease entities, acute leukemia patients had a significantly higher risk of CVC-related infections (2.6, CI 2.1 to 3.8). On the basis of questionnaires submitted to patients from both groups, ultrasound guidance was associated with improved patient comfort and satisfaction. CONCLUSIONS: Ultrasound guidance reduces complications and improves patient comfort. Further studies are needed to define whether acute leukemia patients should be considered a separate category with regard to the higher incidence of infections.

Early tracheostomy in intensive care unit: a retrospective study of 506 cases of video-guided Ciaglia Blue Rhino tracheostomies.

BACKGROUND: Percutaneous dilatational tracheostomy (PDT) is a common procedure in critically ill patients, but the correct timing is still controversial. This study was designed to establish whether an early timing in video-guided Ciaglia Blue Rhino PDT affects the duration of mechanical ventilation (MV) and the length of stay (LOS) in intensive care unit (ICU). Secondary clinical outcomes were the overall hospitalization duration and the mortality rate. METHODS: A retrospective, single-center study of 2,210 patients admitted to the ICU of the Emergency Department of the Careggi Teaching Hospital (Florence, Italy) between 2002 and 2007. Among the 506 patients who underwent PDT, 256 and 250 patients were retrospectively assigned to the early tracheostomy (ET) or late tracheostomy (LT) group according to whether the procedure was performed before (ET) or after (LT) 3 days of MV (median time of procedure execution). RESULTS: The two groups of patients showed comparable demographic and clinical characteristics. The video-guided PDT procedures were performed without major complications in all cases. The average timing of tracheostomy in the ET group was 1.9 +/- 0.9 days, whereas in LT group resulted 6.8 +/- 3.8 days (mean +/- SD). Total hospital LOS and mortality rate were not different between the two groups. However, the duration of MV days and of ICU LOS group were significantly shorter in the ET group (13.3 +/- 9.6 and 16.9 +/- 13.0 days, respectively; p = 0.0001) than in the LT group (16.7 +/- 8.3 days and 20.8 +/- 9.2 days, respectively; p < 0.0001). Stratified analysis by the three major ICU admission diagnosis confirmed that both traumatized and nontraumatized (medical and postsurgical) ET patients had a shorter MV duration and ICU LOS as compared with LT patients. CONCLUSIONS: Video-guided Ciaglia Blue Rhino PDT is safe and easy to perform in ICU. No difference in overall hospital LOS, incidence of pneumonia, and mortality rate between the ET and LT groups was found. However, in both traumatized and nontraumatized patients, shortened duration of ICU LOS and MV in the ET group (

Vacuum-assisted closure device enhances recovery of critically ill patients following emergency surgical procedures.

INTRODUCTION: Critically ill surgical patients frequently develop intra-abdominal hypertension (IAH) leading to abdominal compartment syndrome (ACS) with subsequent high mortality. We compared two temporary abdominal closure systems (Bogota bag and vacuum-assisted closure (VAC) device) in intra-abdominal pressure (IAP) control. METHODS: This prospective study with a historical control included 66 patients admitted to a medical and surgical intensive care unit (ICU) of a tertiary care referral center (Careggi Hospital, Florence, Italy) from January 2006 to April 2009. The control group included patients consecutively treated with the Bogota bag (Jan 2006-Oct 2007), whereas the prospective group was comprised of patients treated with a VAC. All patients underwent abdominal decompressive surgery. Groups were compared based upon their IAP, SOFA score, serial arterial lactates, the duration of having their abdomen open, the need for mechanical ventilation (MV) along with length of ICU and hospital stay and mortality. Data were collected from the time of abdominal decompression until the end of pressure monitoring. RESULTS: The Bogota and VAC groups were similar with regards to demography, admission diagnosis, severity of illness, and IAH grading. The VAC system was more effective in controlling IAP (P < 0.01) and normalizing serum lactates (P < 0.001) as compared to the Bogota bag during the first 24 hours after surgical decompression. There was no significant difference between the SOFA scores. When compared to the Bogota, the VAC group had a faster abdominal closure time (4.4 vs 6.6 days, P = 0.025), shorter duration of MV (7.1 vs 9.9 days, P = 0.039), decreased ICU length of stay (LOS) (13.3 vs 19.2 days, P = 0.024) and hospital LOS (28.5 vs 34.9 days; P = 0.019). Mortality rate did not differ significantly between the two groups. CONCLUSIONS: Patients with abdominal compartment syndrome who were treated with VAC decompression had a faster abdominal closure rate and earlier discharge from the ICU as compared to similar patients treated with the Bogota bag.

Bedside diagnostic laparoscopy to diagnose intraabdominal pathology in the intensive care unit.

INTRODUCTION: Delayed diagnosis of intraabdominal pathology in the intensive care unit (ICU) increases rates of morbidity and mortality. Intraabdominal pathologies are usually identified through presenting symptoms, clinical signs, and laboratory and radiological results; however, these could also delay diagnosis because of inconclusive laboratory tests or imaging results, or the inability to safely transfer a patient to the radiology room. In the current study we evaluated the safety and accuracy of bedside diagnostic laparoscopy to confirm the presence of intraabdominal pathology in an ICU setting. METHODS: This retrospective study, carried out between January 2006 and June 2008, evaluated the diagnostic accuracy of bedside diagnostic laparoscopy performed on patients with a suspicion of ongoing intraabdominal pathology. Clinical indications for bedside diagnostic laparoscopy were: ultrasonography (US) images of gallbladder distension or wall thickening of more than 3 to 4 mm, with or without pericholecystic fluid; elevation of laboratory tests (bilirubin, transaminases, myoglobin, lactate dehydrogenase, creatine phosphokinase, gamma-glutamyltransferase); high level of lactate/metabolic acidosis; CT images inconclusive for intraabdominal pathology; or inability to perform a CT scan. Patients did not undergo bedside diagnostic laparoscopy if they presented clear indications for open surgery, coagulopathy, abdominal wall infection or high intraabdominal pressure. RESULTS: Thirty-two patients underwent bedside diagnostic laparoscopy (Visiport Plus, Autosuture, US), 14 of whom had been admitted to the ICU for major trauma, 12 for sepsis of unknown origin and 6 for complications after cardiac surgery. The procedure was performed on an average of eight days after ICU admission (95% confidence interval = 5 to 15 days) and mean procedure duration was 40 minutes. None of the procedures resulted in complications. Bedside diagnostic laparoscopy was diagnostic for intraabdominal pathology in 15 patients, who subsequently underwent surgery, except in two cases of diffuse gut hypoperfusion. Diagnosis of cholecystitis was obtained in seven cases: two were treated with laparotomic cholecystectomy and five with percutaneous gallbladder drainage positioning. CONCLUSIONS: Bedside diagnostic laparoscopy represents a safe and accurate technique for diagnosing intraabdominal pathology in an ICU setting and should be taken into consideration when patient transfer to radiology or the operating room is considered unsafe, or when routine radiological examinations are not conclusive enough to reach a definite diagnosis.
