ABSTRACT

Background An organization's ability to identify and learn from opportunities for improvement (OFI) is key to increasing diagnostic safety. Many lack effective processes required to capitalize on these learning opportunities. We describe two parallel attempts at creating such a process and identifying generalizable lessons and learn from them. Methods Triggered case review programs were created independently at two organizations, Site 1 (Regions Hospital, HealthPartners, Saint Paul, MN, USA) and site 2 (University of California, San Diego). Both used a five-step process to create the review system and provide feedback: (1) identify trigger criteria; (2) establish a review panel; (3) develop a system to conduct reviews; (4) perform reviews; and (5) provide feedback. Results Site 1 identified 112 OFI in 184 case reviews (61%), with 66 (59%) provider OFI and 46 (41%) system OFI. Site 2 focused mainly on systems OFI identifying 105 OFI in 346 cases (30%). Opportunities at both sites were variable; common themes included test result management and communication across teams in peri-procedural care and with consultants. Of provider-initiated reviews, 67% of cases had an OFI at site 1 and 87% at site 2. Conclusions Lessons learned include the following: (1) peer review of cases provides opportunities to learn and calibrate diagnostic and management decisions at an organizational level; (2) sharing cases in review groups supports a culture of open discussion of OFIs; (3) reviews focused on diagnostic safety identify opportunities that may complement other organization-wide review opportunities.

ABSTRACT

OBJECTIVE: Uncontrolled hyperglycemia and iatrogenic hypoglycemia represent common and frequently preventable quality and safety issues. We sought to demonstrate the effectiveness of a hypoglycemia reduction bundle, proactive surveillance of glycemic outliers, and an interdisciplinary data-driven approach to glycemic management. POPULATION: all hospitalized adult non-intensive care unit (non-ICU) patients with hyperglycemia and/or a diagnosis of diabetes admitted to our 550-bed academic center across 5 calendar years (CYs). INTERVENTIONS: hypoglycemia reduction bundle targeting most common remediable contributors to iatrogenic hypoglycemia; clinical decision support in standardized order sets and glucose management pages; measure-vention (daily measurement of glycemic outliers with concurrent intervention by the inpatient diabetes team); educational programs. MEASURES AND ANALYSIS: Pearson chi-square value with relative risks (RRs) and 95% confidence intervals (CIs) were calculated to compare glycemic control, hypoglycemia, and hypoglycemia management parameters across the baseline time period (TP1, CY 2009-2010), transitional (TP2, CY 2011-2012), and mature postintervention phase (TP3, CY 2013). Hypoglycemia defined as blood glucose <70 mg/dL, severe hypoglycemia as <40 mg/dL, and severe hyperglycemia >299 mg/dL. RESULTS: A total of 22,990 non-ICU patients, representing 94,900 patient-days of observation were included over the 5-year study. The RR TP3:TP1 for glycemic excursions was reduced significantly: hypoglycemic stay, 0.71 (95% CI, 0.65 to 0.79); severe hypoglycemic stay, 0.44 (95% CI, 0.34 to 0.58); recurrent hypoglycemic day during stay, 0.78 (95% CI, 0.64 to 0.94); severe hypoglycemic day, 0.48 (95% CI, 0.37 to 0.62); severe hyperglycemic day (>299 mg/dL), 0.76 (95% CI, 0.73 to 0.80). CONCLUSION: Hyperglycemia and hypoglycemia event rates were both improved, with the most marked effect on severe hypoglycemic events. Most of these interventions should be portable to other hospitals.

ABSTRACT

BACKGROUND: It is not clear which serum creatinine-based glomerular filtration rate (GFR)-estimating model performs best in kidney donors. STUDY DESIGN: Study of diagnostic accuracy. SETTING & PARTICIPANTS: From a population of 3,698 kidney donors, 255 donors underwent iohexol GFR measurement (mGFR). INDEX TEST (INTERVENTION): mGFR by means of plasma disappearance of iohexol. REFERENCE TEST OR OUTCOME: GFR was estimated (eGFR) by using the Cockcroft-Gault equation (eGFR(CG)), Mayo Clinic equation (eGFR(MC)), and Modification of Diet in Renal Disease (MDRD) Study equation (eGFR(MDRD)). RESULTS: Mean mGFR was 71.8 +/- 11.8 mL/min/1.73 m(2), and 85.5% had mGFR greater than 60 mL/min/1.73 m(2). eGFR(CG) underestimated mGFR by 3.96 +/- 13.3 mL/min/1.73 m(2) and was within 30% of mGFR 89.4% of the time. eGFR(MC) overestimated mGFR by 8.44 +/- 11.9 mL/min/1.73 m(2) and was within 30% of mGFR in 83.1% of cases. eGFR(MDRD) underestimated mGFR by only 0.43 +/- 11.7 mL/min/1.73 m(2), and the proportion within 30% of mGFR was greatest in the tested model; 94.1% of the time. However, eGFR(MC) was most accurate in classifying donors according to having eGFR less than 60 mL/min/1.73 m(2). LIMITATIONS: Lack of ethnic diversity and response bias. CONCLUSIONS: The MDRD Study equation is least biased, and because it is routinely reported by most laboratories, it is the best readily available model for estimating GFR in kidney donors.

ABSTRACT

BACKGROUND: We report the case of a 56-year-old male with multiple myeloma in whom recurrent fevers and leukocytosis delayed potentially effective chemotherapy due to concern for active infection. DESIGN AND MEASUREMENTS: A thorough infectious workup, including CT and PET scans, was negative. The patient was eventually found to have an elevated serum granulocyte colony-stimulating factor (G-CSF) of 113 pg/ml (normal range 0.0 - 39.1 pg/ml), which was likely the cause of his persistent leukocytosis and fevers. Multiagent chemotherapy was initiated, and the fevers resolved in the next 4 days. RESULTS: Leukocyte concentrations trended down after initiation of chemotherapy, but it is uncertain how much of the decline was attributable to immunosuppression. CONCLUSION: We report this well-documented case to demonstrate that G-CSF production should be considered as a cause of unexplained fever and leukocytosis in patients with multiple myeloma to prevent inappropriate and delayed definitive diagnosis and treatment.
