Abstract Objective Risk scores and accelerated diagnostic protocols can identify chest pain patients with low risk of major adverse cardiac event who could be discharged early from the ED , saving time and costs. We aimed to derive and validate a chest pain score and accelerated diagnostic protocol ( ADP ) that could safely increase the proportion of patients suitable for early discharge. Methods Logistic regression identified statistical predictors for major adverse cardiac events in a derivation cohort. Statistical coefficients were converted to whole numbers to create a score. Clinician feedback was used to improve the clinical plausibility and the usability of the final score (Emergency Department Assessment of Chest pain Score [ EDACS ]). EDACS was combined with electrocardiogram results and troponin results at 0 and 2 h to develop an ADP ( EDACS‐ADP ). The score and EDACS‐ADP were validated and tested for reproducibility in separate cohorts of patients. Results In the derivation ( n = 1974) and validation ( n = 608) cohorts, the EDACS‐ADP classified 42.2% (sensitivity 99.0%, specificity 49.9%) and 51.3% (sensitivity 100.0%, specificity 59.0%) as low risk of major adverse cardiac events, respectively. The intra‐class correlation coefficient for categorisation of patients as low risk was 0.87. Conclusion The EDACS‐ADP identified approximately half of the patients presenting to the ED with possible cardiac chest pain as having low risk of short‐term major adverse cardiac events, with high sensitivity. This is a significant improvement on similar, previously reported protocols. The EDACS‐ADP is reproducible and has the potential to make considerable cost reductions to health systems.

Background: An institutional policy was previously established for patients with diabetes on insulin pump therapy undergoing elective surgical procedures. Method: Electronic medical records were reviewed to assess documentation of insulin pump status and glucose monitoring during preoperative, intraoperative, and postanesthesia care unit (PACU) phases of care. Results: Twenty patients with insulin pumps underwent 23 procedures from March 1 to December 31, 2011. Mean (standard deviation) age was 58 (13) years, mean diabetes duration was 28 (17) years, and mean duration of insulin pump therapy was 7 (6) years. Nearly all cases (86%) during the preoperative phase had the presence of the device documented—an improvement over the 64% noted in data collected before the policy. Intraoperatively, 13 cases (61%) had the presence of the pump documented, which was higher than the 28% before implementation of the policy. However, documentation of pump status was found in only 38% in the PACU and was actually less than the 60% documented previously. Over 90% of cases had glucose checked in the preoperative area and the PACU, and only 60% had it checked intraoperatively, which was nearly identical to the percentages seen before policy implementation. No adverse events occurred when insulin pump therapy was continued. Conclusions: Although some processes still require improvement, preliminary data suggest that the policy for perioperative management of insulin pumps has provided useful structure for care of these cases. The data thus far indicate that insulin pump therapy can be continued safely during the perioperative period.

Case reports indicate that diabetes patients receiving outpatient insulin pump therapy have been allowed to continue treatment during surgical procedures. Although allowed during surgery, there is actually little information in the medical literature on how to manage patients receiving insulin pump therapy during a planned surgical procedure. A multidisciplinary work group reviewed current information regarding the use of insulin pumps in the perioperative period. Although the work group identified safety issues specific to surgical scenarios, it believed that with the use of standardized guidelines and a checklist, continuation of insulin pump therapy during the perioperative period is feasible. A sample set of protocols have been developed and are summarized. A policy outlining clear procedures should be established at the institutional level to guide physicians and other staf if the devices are to be employed during the perioperative period. Additional clinical experience with the technology in surgical scenarios is needed, and consensus should be developed for insulin pump use in the perioperative phases of care.

Background: Treating hyperglycemia promotes better outcomes among inpatients. Knowledge deficits about management of inpatient diabetes are prevalent among resident physicians, which may affect the care of a substantial number of these patients. Methods: A computer-based training (CBT) curriculum on inpatient diabetes and hyperglycemia was developed and implemented for use by resident physicians and focuses on several aspects of the management of inpatient diabetes and hyperglycemia: (1) review of importance of inpatient glucose control, (2) overview of institution-specific data, (3) triaging and initial admission actions for diabetes or hyperglycemia, (4) overview of pharmacologic management, (5) insulin-dosing calculations and ordering simulations, (6) review of existing policies and procedures, and (7) discharge planning. The curriculum was first provided as a series of lectures, then formatted and placed on the institutional intranet as a CBT program. Results: Residents began using the inpatient CBT in September 2008. By August 2009, a total of 29 residents had participated in CBT: 8 in family medicine, 12 in internal medicine, and 9 in general surgery. Most of the 29 residents confirmed that module content met stated objectives, considered the information valuable to their inpatient practices, and believed that the quality of the online modules met expectations. The majority reported that the modules took just the right amount of time to complete (typically 30 min each). Conclusions: Improvement in inpatient diabetes care requires continuous educational efforts. The CBT format and curriculum content were well accepted by the resident physicians. Ongoing assessment must determine whether resident practice patterns are influenced by such training.

We present an overview of strategies our institution has taken to understand the state of its inpatient diabetes management. We first describe how we utilized information systems to assess inpatient glycemic control and insulin management in noncritically ill patients and discuss our findings regarding mean bedside glucose levels, the prevalence and frequency hypoglycemic and hyperglycemic events, the patterns of insulin therapy, and evidence of inpatient clinical inertia. We also review the development of a survey to determine practitioner attitudes and beliefs about inpatient diabetes. Results of this survey study found that, in general, practitioners believed in the importance of controlling hyperglycemia but were not comfortable with many aspects of inpatient diabetes care, particularly with the use of insulin. Finally, we suggest steps to follow in developing a quality-improvement program for hospitals.

Objective Multiple-valve (MUV) procedures currently exhibit higher operative mortality than do single-valve procedures, but a paucity of scientific information exists to explain the observation. This topic was examined using The Society of Thoracic Surgeons Database. Methods All patients in the The Society of Thoracic Surgeons data set undergoing valve surgery (except pulmonary valve and aortic root operations) from 1993 through 2007 were identified (N = 623,039). Baseline characteristics and postoperative outcomes were contrasted between all seven combinations of single-valve and MUV procedures involving aortic, mitral, and tricuspid valves. Seven independent logistic regression analyses were performed, based on the seven procedures, and multivariable risk factors for mortality were compared, with emphasis on single-valve versus MUV procedures. Results Baseline characteristics for MUV procedures (n = 67,926) shared many similarities to those for single-valve procedures (n = 555,113), including age, ejection fraction, and comorbidities. Preoperative renal failure, New York Heart Association class III to IV, nonelective presentation, and reoperation were slightly more common in MUV subsets, and coronary bypass was less frequent. Operative mortality was almost double for MUV as compared with single-valve procedures (10.7% vs 5.7%, P = 0.0001). Categorical predictors with the largest odds ratios for mortality were emergency status, renal failure, and second reoperation. However, predictors for mortality were generally consistent in order and magnitude between the single-valve and MUV subgroups. Conclusions Despite similarities in preoperative profiles of the patients undergoing single-valve and MUV procedures, mortality for MUV surgery remains considerably higher. Determinants of operative mortality and morbidity differ little across the procedural groups, and these findings serve as a benchmark for future studies, as well as suggest a continued search for explanations of poorer MUV outcomes.

BackgroundPatients with disorders of gastrointestinal function may undergo unnecessary treatment if misdiagnosed as motility disorders.ObjectiveTo report on clinical features, medical, surgical, and psychiatric comorbidities, and prior treatments of a patient cohort diagnosed concurrently with nonpsychogenic rumination syndrome and pelvic floor dysfunction (also termed rectal evacuation disorder).MethodsFrom a consecutive series (1994–2013) of 438 outpatients with rectal evacuation disorders in the practice of a single gastroenterologist at a tertiary care centre, 57 adolescents or adults were diagnosed with concomitant rumination syndrome. All underwent formal psychological assessment or completed validated questionnaires.ResultsAll 57 patients (95% female) fulfilled Rome III criteria for rumination syndrome; rectal evacuation disorder was confirmed by testing of anal sphincter pressures and rectal balloon evacuation. Prior to diagnosis, most patients underwent multiple medical and surgical treatments (gastrostomy, gastric fundoplication, other gastric surgery, ileostomy, colectomy) for their symptoms. Psychological comorbidity was identified in 93% of patients. Patients were managed predominantly with psychological and behavioural approaches: diaphragmatic breathing for rumination and biofeedback retraining for pelvic floor dysfunction.ConclusionsAwareness of concomitant rectal evacuation disorder and rumination syndrome and prompt identification of psychological comorbidity are keys to instituting behavioural and psychological methods to avoid unnecessary treatment.
