Effects of Computerized Decision Support Systems on Blood Glucose Regulation in Critically Ill Surgical Patients

BACKGROUND The use of computerized decision support systems (CDSS) in glucose control for critically ill surgical patients has been reported in both diabetic and nondiabetic patients. Prospective studies evaluating its effect on glucose control are, however, lacking. The objective of this study was to evaluate patient-specific computerized IV insulin dosing on blood glucose levels (BGLs) by comparing patients treated pre-CDSS with those treated post-CDSS. STUDY DESIGN A prospective study was performed in 4 surgical ICUs and 1 progressive care unit comparing patient data pre- and post-implementation of CDSS. The primary outcomes measures were the impact of the CDSS on glycemic control in this population and on reducing the incidence of severe hypoglycemia. RESULTS Data on 1,682 patient admissions were evaluated, which corresponded to 73,290 BGLs post-CDSS compared with 44,972 BGLs pre-CDSS. The percentage of hyperglycemic events improved, with BGLs of >150 mg/dL decreasing by 50% compared with 6-month historical controls during the 18-month study period from July 2010 through December 2011. This was true for all 5 units individually (p < 0.0001, by one sample sign test). In addition, severe hypoglycemia (defined as BGL <40 mg/dL) decreased from 1% to 0.05% after implementing CDSS (p < 0.0001 by 2-sided binomial test). CONCLUSIONS Patients whose BGLs were managed using CDSS were statistically significantly more likely to have a glucose reading under control (<150 mg/dL) than in the 6-month historical controls and to avoid serious hypoglycemia (p < 0.0001).

Surgery for Crohn's disease and anti-TNF agents: the changing scenario.

Surgery has been a mainstay of therapy for Crohn’s disease for a long time, essentially as a consequence of the fairly modest efficacy of traditional medications such as immunomodulators, antibiotics and 5-ASA, especially in severe cases. However, in the past decade and half, the advent of anti-TNF agents has greatly changed the medical approach to this disease and may modify its general management as well. Here, we have reviewed the current literature on incidence of surgery, timing of surgery and postoperative recurrence of Crohn’s disease before and after the advent of anti-TNF agents. In addition, we have reviewed the risk of perioperative complications in patients on anti-TNF agents before surgery. The data show that the use of these medications is changing or expecting to change shortly a number of surgical aspects of Crohn’s disease management.

Contact isolation is a risk factor for venous thromboembolism in trauma patients.

BACKGROUND Contact isolation (CI) is a series of precautions used to prevent the transmission of medically significant infectious pathogens in the health care setting. Our institution’s implementation of CI includes limiting patient movement to the assigned room. Our objective was to define the association between CI and venous thromboembolism (VTE) at our Level I trauma center. METHODS Our institution’s prospective trauma database was retrospectively queried for all patients admitted to the trauma service between January 1, 2011, and December 31, 2012. Data including demographics, Injury Severity Score (ISS), preexisting medical conditions, injury type, and VTE development were collected. CI status data were obtained from our institution’s infection control database. &khgr;2 was used to examine the unadjusted relationship between CI status and VTE. As the groups were not equivalent, logistic regression was then used to examine the relationship between CI and VTE while adjusting for relevant covariates including sex, age, ISS, and comorbidities. RESULTS Of the 4,423 trauma patients admitted during the study period, 4,318 (97.6%) had complete records and were included in subsequent analyses. A total of 249 (5.8%) of the patients were on CI. VTE occurred in 44 patients (17.7%) on CI versus 141 patients (3.5%) who were not isolated (p < 0.0001; odds ratio, 6.0; 95% confidence interval, 4.1–8.6). With the use of lasso [least absolute shrinkage and selection operator] regression to adjust for patient risk factors, this relationship remained highly significant (p < 0.0001; odds ratio, 2.61; 95% confidence interval, 1.7–4.0). CONCLUSION CI, ISS, hospital length of stay, and cardiac comorbidity were associated with VTE. After adjustment for other risk factors, CI remained most strongly associated with VTE. Although any medical intervention may come with unintended consequences, the risks and benefits of CI in this population need to be reevaluated. Further study is planned to identify opportunities to mitigate this increased VTE risk. LEVEL OF EVIDENCE Prognostic/epidemiologic study, level III; therapeutic study, level IV.

Higher surgical critical care staffing levels are associated with improved National Surgical Quality Improvement Program quality measures.

BACKGROUND The changing face of American health care demands careful scrutiny of resource allocation. The impact of the surgical intensivist model on general surgical quality measures has not been studied. Our objective was to investigate the relationship between surgical critical care staffing and indicators of general surgical quality measured by the National Surgical Quality Improvement Program (NSQIP). METHODS We retrospectively examined the number of attending surgical intensivists at our tertiary care center biannually from January 2008 through June 2012. Risk-adjusted indicators of general surgical quality were captured and reported semiannually by NSQIP. Mortality, overall morbidity, patients on ventilator for more than 48 hours, unplanned intubations, and venous thromboembolism were included. Student’s t test was used to compare the staffing levels and associated NSQIP odds ratios of a 3-year control period of full commitment with a 2-year period following significant provider attrition. RESULTS The number of full-time surgical intensivists ranged from 2 to 8, with a period of rapid decline in late 2010 to early 2011 followed by slow recovery. There was a mean of 6.6 surgical intensivists during the 3 years before the decline and a mean of 4 in the 2 years after the decline and recovery (p < 0.005). This period of decline was associated with a significant increase in the odds ratio of ventilation for more than 48 hours (before, 0.936; after, 1.87; p = 0.0086) and of venous thromboembolism (before, 0.844; after 1.43; p = 0.0268). A trend in increased unplanned intubations was also observed. Overall morbidity and mortality were not affected. Notably, quality indicators seemed to rapidly approach baseline levels as new surgical intensivists were recruited. CONCLUSION Institutional commitment to recruitment and retention of a surgical critical care team leads to improved NSQIP general surgery quality measures. LEVEL OF EVIDENCE Care management study, level IV.

Opioid prescribing practices during implementation of an enhanced recovery program at a tertiary care hospital

Background: Enhanced recovery programs have demonstrated a decrease in opioid use in hospitals where patients have undergone colorectal surgery. This study is to investigate whether similar decreases in opioid prescribing are achieved at discharge and postdischarge. Methods: Patients undergoing colorectal surgery November 2014–November 2016 were reviewed. Postdischarge opioid prescribing was quantified in morphine milligram equivalents at time of discharge, 30 days postdischarge, and 60 days postdischarge. Linear regression models were used to examine factors predictive of opioid prescribing. Results: A total of 324 patients treated on enhanced recovery program protocol and 451 patients off enhanced recovery program protocol were reviewed. Enhanced recovery program patients had shorter lengths of stay: 6.74 ± 5.3 vs 9.0 ± 7.0 days (mean ± standard deviation; P < .0001). At discharge, enhanced recovery program patients were prescribed higher amounts of opioids (morphine milligram equivalent 307.4 ± 286.3 vs 242.5 ± 243.1 [mean ± SD]; P=.001) and were more likely to receive additional opioid prescriptions in the next 30 days (28.7% vs 18.85%; P=.0013). Linear regression models suggest that preoperative opioid use, age, and treatment on enhanced recovery program protocol were predictive of opioid prescribing (morphine milligram equivalent) at time of discharge. Conclusion: Enhanced recovery program patients received more opioid prescribing (morphine milligram equivalent) at discharge and within the first 30 days postdischarge. Alternative confounding variables require further investigation.

Doctors are not pilots and patients are not airplanes: Quality improvement in medicine

Abstract The Institute of Medicine of the National Academy of Science issued a report in 1999 entitled “To Err Is Human.” It described errors in hospitals which led to between 44,000 and 99,000 deaths per year. This was the “tipping point” toward self-evaluation and quality improvement. Medicine has slowly developed quality improvement methodologies that seem to work. Surgery leads the way. This article will go through some of the history of quality improvement with the difficulty comparing patients and defining outcomes, along with the difficulties changing physician behavior. The challenges of implementing quality improvement across an entire hospital will be demonstrated.
