Prevention of Catheter-Related Blood Stream Infection: Back to Basics?

Background: Central venous catheter (CVC)-related infections are a substantial problem in the intensive care unit (ICU). Our infection control team initiated the routine use of antiseptic-coated (chlorhexidine-silver sulfadiazine; Chx-SS) CVCs in our adult ICUs to reduce catheter-associated (CA) and catheter-related (CR) blood stream infection (BSI) as we implemented other educational and best practice standardization strategies. Prior randomized studies documented that the use of Chx-SS catheters reduces microbial colonization of the catheter compared with an uncoated standard (Std) CVC but does not reduce CR-BSI. We therefore implemented the routine use of uncoated Std CVCs in our surgical ICU (SICU) and examined the impact of this change. Hypothesis: The use of uncoated Std CVCs does not increase CR-BSI rate in an SICU. Methods: Prospective evaluation of universal use of uncoated Std CVCs, implemented November 2007 in the SICU. The incidences of CA-BSI and CR-BSI were compared during November 2006-October 2007 (universal use of Chx-SS CVCs) and November 2007-October 2008 (universal use of Std CVCs) by t-test. The definitions of the U.S. Centers for Disease Control and Prevention were used for CA-BSI and CR-BSI. Patient data were collected via a dedicated Acute Physiology and Chronic Health Evaluation (APACHE) III coordinator for the SICU. Results: Annual use of CVCs increased significantly in the last six years, from 3,543 (2001) to 5,799 (2006) total days. The APACHE III scores on day 1 increased from a mean of 54.4 in 2004 to 55.6 in 2008 (p = 0.0010; 95% confidence interval [CI] 1.29-5.13). The mean age of the patients was unchanged over this period, ranging from 58.2 to 59.6 years. The Chx-SS catheters were implemented in the SICU in 2002. Data regarding the specific incidence of CR-BSI were collected beginning at the end of 2005, with mandatory catheter tip cultures when CVCs were removed. Little difference was identified in the incidence of BSI between the interval with universal Chx-SS use and that with Std CVC use. (Total BSI 0.7 vs. 0.8 per 1,000 catheter days; CA-BSI 0.5 vs. 0.8 per 1,000 catheter days; CR-BSI 0.2 vs. 0 per 1,000 catheter days.) No difference was seen in the causative pathogens of CA-BSI or CR-BSI. Conclusion: Eliminating the universal use of Chx-SS-coated CVCs in an SICU with a low background incidence of CR-BSIs did not result in an increase in the rate of CR-BSIs. This study documents the greater importance of adherence to standardization of the processes of care related to CVC placement than of coated CVC use in the reduction of CR-BSI.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/90456/1/sur-2E2009-2E082.pd

EQIP\u27s First Year: A Step Closer to Higher Quality in Surgical Education.

OBJECTIVE: To describe the first year of the Educational Quality Improvement Program (EQIP) DESIGN: The Educational Quality Improvement Program (EQIP) was formed by the Association of Program Directors in Surgery (APDS) in 2018 as a continuous educational quality improvement program. Over 18 months, thirteen discrete goals for the establishment of EQIP were refined and executed through a collaborative effort involving leaders in surgical education. Alpha and beta pilots were conducted to refine the data queries and collection processes. A highly-secure, doubly-deidentified database was created for the ingestion of resident and program data. SETTING & PARTICIPANTS: 36 surgical training programs with 1264 trainees and 1500 faculty members were included in the dataset. 51,516 ERAS applications to programs were also included. Uni- and multi-variable analysis was then conducted. RESULTS: EQIP was successfully deployed within the timeline described in 2020. Data from the ACGME, ABS, and ERAS were merged with manually entered data by programs and successfully ingested into the EQIP database. Interactive dashboards have been constructed for use by programs to compare to the national cohort. Risk-adjusted multivariable analysis suggests that increased time in a technical skills lab was associated with increased success on the ABS\u27s Qualifying Examination, alone. Increased time in a technical skills lab and the presence of a formal teaching curriculum were associated with increased success on both the ABS\u27s Qualifying and Certifying Examination. Program type may be of some consequence in predicting success on the Qualifying Examination. CONCLUSIONS: The APDS has proved the concept that a highly secure database for the purpose of continuous risk-adjusted quality improvement in surgical education can be successfully deployed. EQIP will continue to improve and hopes to include an increasing number of programs as the barriers to participation are overcome

Venoarteriovenous ECMO in Concomitant Acute Respiratory Distress Syndrome and Cardiomyopathy Associated with COVID-19 Infection

In the most severe cases, novel coronavirus (SARS-CoV-2) infection leads to Acute Respiratory Distress Syndrome which may be refractory to standard medical interventions including mechanical ventilation. There are growing reports of the use of venovenous (VV) extracorporeal membrane oxygenation (ECMO) in these cases. A subset of critically ill COVID-19 patients develops cardiomyopathy as well, manifested by cardiogenic shock with reduced ejection fraction, dysrhythmias, and subsequent increase in mortality. One strategy for managing ARDS with an element of cardiogenic shock is venoarteriovenous (VAV) ECMO. Less than 1% of the cases in the worldwide ELSO COVID-19 database employed any form of hybrid cannulation. To date, there has only been one reported case of patient salvage with arterial or partial arterial support. We present a case that demonstrates the potential role of VAV ECMO in the case of concomitant severe ARDS with cardiomyopathy in the setting of COVID-19 infection

Evaluation of Minnesota Score in the Allocation of Venovenous Extracorporeal Membrane Oxygenation During Resource Scarcity

Background. In this study, we evaluate the previously reported novel Minnesota Score for association with in-hospital mortality and allocation of venovenous extracorporeal membrane oxygenation in patients with acute respiratory distress syndrome with or without SARS-CoV-2 pneumonia. Methods. This was a retrospective cohort study across four extracorporeal membrane oxygenation centers in Minnesota. Logistic regression was used to assess the relationship between the scores and in-hospital mortality, duration of ECMO cannulation, and discharge disposition. Priority groups were established statistically by maximizing the sum of sensitivity and specificity and compared to the previous qualitatively established priority groups. Results. Of 124 patients included in the study, 38% were treated for COVID-19 acute respiratory distress syndrome. The median age was 48 years, and 73% were male. The in-hospital mortality rate was 38%. The Minnesota Score was significantly associated with in-hospital mortality only (OR 1.13, p=0.02). Statistically determined cut points were similar to qualitative cut points. SARS-CoV-2 status did not change the findings. Conclusions. In our patient cohort, the Minnesota Score is associated with increased mortality. With further validation, proposed priority groups could be utilized for allocation of ECMO in times of increasing scarcity

The APDS General Surgery Education Quality Improvement Program (EQIP).

BACKGROUND: Although the ACGME has called for outcomes-based evaluation of residency programs, few metrics or benchmarks exist connecting educational processes with resident educational outcomes. To address this deficiency, a national Education Quality Improvement Program (EQIP) for General Surgery training is proposed. METHODS: We describe the initial efforts to create this platform. In addition, a national survey was administered to 330 Program Directors to assess their interest in and concerns about a continuous educational quality improvement project. RESULTS: We demonstrate that through a collaborative process and the support of the Association of Program Directors in Surgery (APDS), we were able to develop the groundwork for a national surgical educational improvement project, now called EQIP. The survey response rate was 45.8% (152 of 332 programs) representing a mix of university (55.3%), university-affiliated (18.4%), independent (24.3%), and military (2.0%) programs. Most respondents (66.2%) had not previously heard of EQIP. Most respondents (69.7%) believe that educational outcomes can be measured. The majority of respondents indicated they believed EQIP could be successful (57%). Only 2.3% thought EQIP would not be successful. Almost all programs (98.7%) expressed a willingness to participate, although 19.1% did not believe that they had adequate resources to participate. CONCLUSION: The APDS EQIP platform holds promise as a useful and achievable method to obtain educational outcomes data. These data can be used as a basis for continuous surgical educational quality improvement. General Surgery Program Directors have expressed enthusiasm for EQIP and are willing to participate in the program examining outcomes of General Surgery training programs, with an ultimate goal of improving overall residency training
