Utilization of lean project management principles and health informatics to reduce operating room delays in a vascular surgery practice.

OBJECTIVES: Perioperative inefficiency can increase cost. We describe a process improvement initiative that addressed preoperative delays on an academic vascular surgery service. METHODS: First case vascular surgeries from July 2019-January 2020 were retrospectively reviewed for delays, defined as late arrival to the operating room (OR). A stakeholder group spearheaded by a surgeon-informaticist analyzed this process and implemented a novel electronic medical records (EMR) preoperative tool with improved preoperative workflow and role delegation; results were reviewed for 3 months after implementation. RESULTS: 57% of cases had first case on-time starts with average delay of 19 min. Inappropriate preoperative orders were identified as a dominant delay source (average delay = 38 min). Three months post-implementation, 53% of first cases had on-time starts with average delay of 11 min (P < 0.05). No delays were due to missing orders. CONCLUSIONS: Inconsistent preoperative workflows led to inappropriate orders and delays, increasing cost and decreasing quality. A novel EMR tool subsequently reduced delays with projected savings of $1,200/case. Workflow standardization utilizing informatics can increase efficiency, raising the value of surgical care.

Using open-source intelligence to identify early signals of COVID-19 in Indonesia.

OBJECTIVE: Open-source data from online news reports and informal sources may provide information about outbreaks before official notification. This study aims to evaluate the use of open-source data from the epidemic observatory, EpiWATCH, to identify the early signals of pneumonia of unknown cause as a proxy for COVID-19 in Indonesia. METHODS: Using open-source data on pneumonia of unknown cause in Indonesia between 1 November 2019 and 31 March 2020 (extracted from EpiWATCH, an open-source epidemic observatory), a descriptive analysis was performed to identify the trend of pneumonia of unknown cause in Indonesia before official notification of COVID-19 cases. RESULTS: A rise in reports of pneumonia of unknown cause was identified in Indonesia, starting from late January 2020. There were 304 reported cases of pneumonia of unknown cause, 30 of which occurred before the identification of the first COVID-19 cases on 2 March 2020. The early signals of pneumonia of unknown cause in Indonesia may indicate possible unrecognized circulation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) before official detection. DISCUSSION: Open-source data may provide rapid, unvalidated information for early detection of outbreaks. Although unvalidated, such information may be used to supplement or trigger investigation and testing. As EpiWATCH sources global information, this methodology can be repeated for other countries within the Western Pacific Region, and for other diseases.

Association of diabetes with frequency and cost of hospital admissions: a retrospective cohort study.

BACKGROUND: Acute inpatient hospital admissions account for more than half of all health care costs related to diabetes. We sought to identify the most common and costly conditions leading to hospital admission among patients with diabetes compared with patients without diabetes. METHODS: We used data from the General Internal Medicine Inpatient Initiative (GEMINI) study, a retrospective cohort study, of all patients admitted to a general internal medicine service at 7 Toronto hospitals between 2010 and 2015. The Canadian Institute for Health Information (CIHI) Most Responsible Diagnosis code was used to identify the 10 most frequent reasons for admission in patients with diabetes. Cost of hospital admission was estimated using the CIHI Resource Intensity Weight. Comparisons were made between patients with or without diabetes using the Pearson χ2 test for frequency and distribution-free confidence intervals (CIs) for median cost. RESULTS: Among the 150 499 hospital admissions in our study, 41 934 (27.8%) involved patients with diabetes. Compared with patients without diabetes, hospital admissions because of soft tissue and bone infections were most frequent (2.5% v. 1.9%; prevalence ratio [PR] 1.28, 95% CI 1.19-1.37) and costly (Can$8794 v. Can$5845; cost ratio [CR] 1.50, 95% CI 1.37-1.65) among patients with diabetes. This was followed by urinary tract infections (PR 1.16, 95% CI 1.11-1.22; CR 1.23, 95% CI 1.17-1.29), stroke (PR 1.13, 95% CI 1.07-1.19; CR 1.19, 95% CI 1.14-1.25) and electrolyte disorders (PR 1.11, 95% CI 1.03-1.20; CR 1.20, 95% CI 1.08-1.34). INTERPRETATION: Soft tissue and bone infections, urinary tract infections, stroke and electrolyte disorders are associated with a greater frequency and cost of hospital admissions in patients with diabetes than in those without diabetes. Preventive strategies focused on reducing hospital admissions secondary to these disorders may be beneficial in patients with diabetes.

The RCA ReCAst: A Root Cause Analysis Simulation for the Interprofessional Clinical Learning Environment.

PROBLEM: The Accreditation Council for Graduate Medical Education calls for resident participation in real or simulated interprofessional analysis of a patient safety event. There are far more residents who must participate in these investigations than available institutional root cause analyses (RCAs) to accommodate them. To correct this imbalance, the authors developed an institutionally sponsored, interprofessional RCA simulation program and implemented it across all graduate medical education (GME) residency programs at the Hospital of the University of Pennsylvania. APPROACH: The authors developed RCA simulations based upon authentic adverse events experienced at their institution. To provide relevance to all GME programs, RCA simulation cases varied widely and included examples of errors involving high-risk medications, communication, invasive procedures, and specimen labeling. Each simulation included residents and other health care professionals such as nurses or pharmacists whose disciplines were involved in the actual event. Participants adopted the role of RCA investigation team, and in small groups systematically progressed through the RCA process. OUTCOMES: A total of 289 individuals from 18 residency programs participated in an RCA simulation in 2019-2020. This included 84 interns (29%), 123 residents (43%), 20 attending physicians (7%), and 62 (21%) other health care professionals. There was an increase in ability of GME trainees to correctly identify factors required for an RCA investigation (62% pre vs 80% post, P = .02) and an increase in intent to "always report" for each adverse event category (3% pre vs 37% post, P < .001) following the simulation. NEXT STEPS: The authors plan to expand the RCA simulation program to other GME clinical sites while striving to involve all GME learners in this educational experience at least once during training. Additionally, by collaborating with health system patient safety leaders, they will annually review all new RCAs to identify cases suitable for simulation adaptation.

Improving the Effectiveness of Root Cause Analysis in Hospitals.

Improving patient safety within hospitals has become a major focal point for administrative and clinical action. Root Cause Analysis (RCA) is an analytical tool used by hospitals in quality improvement and patient safety efforts. While hospitals have widely embraced RCA, the effectiveness of the RCA process has been questioned in recent years. Based on a literature review and feedback from practicing administrators, this paper identifies current barriers to the effectiveness of the RCA process, and suggests actions to overcome them. A more effective RCA process will enable hospitals to establish a safer and more trustworthy care environment for patients.

Reevaluation of risk factors for time to subsequent events after first stroke occurrence using a new weighted all-cause effect measure.

BACKGROUND: Risk diseases and risk factors for stroke include atrial fibrillation, hypertension, diabetes mellitus, smoking, and elevated LDL-cholesterol. Due to modern treatment options, the impact of these risk diseases on subsequent cardiovascular events or death after a first stroke is less clear and needs to be elucidated. We therefore aimed to get insights into the persistence of adverse prognostic effects of these risk diseases and risk factors on subsequent stroke or death events 1 year after the first stroke by using the new weighted all-cause hazard ratio. METHODS: This study evaluates the 1 year follow-up of 470 first ever stroke cases identified in the area of Ludwigshafen, Germany, with 23 deaths and 34 subsequent stroke events. For this purpose, the recently introduced "weighted all-cause hazard ratio" was used, which allows a weighting of the competing endpoints within a composite endpoint. Moreover, we extended this approach to allow an adjustment for covariates. RESULTS: None of these risk factors and risk diseases, most probably being treated after the first stroke, remained to be associated with a subsequent death or stroke [weighted hazard ratios (95% confidence interval) for diabetes mellitus, atrial fibrillation, high cholesterol, hypertension, and smoking are 0.4 (0.2-0.9), 0.8 (0.4-2.2), 1.3 (0.5-2.5), 1.2 (0.3-2.7), 1.6 (0.8-3.6), respectively]. However, when analyzed separately in terms of death and stroke, the risk factors and risk diseases under investigation affect the subsequent event rate to a variable degree. CONCLUSIONS: Using the new weighted hazard ratio, established risk factors and risk diseases for the occurrence of a first stroke do not remain to be significant predictors for subsequent events like death or recurrent stroke. It has been demonstrated that the new weighted hazard ratio can be used for a more adequate analysis of cardiovascular risk and disease progress. The results have to be confirmed within a larger study with more events.

Root cause analysis of pre-microscopic errors in anatomical pathology using Eindhoven classification.

OBJECTIVE: To evaluate pre-microscopic errors in anatomical pathology. METHODS: The cross-sectional descriptive study was conducted at the Department of Pathology of a tertiary care hospital in Lahore, Pakistan, from September, 2016, to January, 2017, and comprised surgical pathology specimens. Errors were noted across the pre-microscopic process. Defects per million opportunities were calculated to determine sigma metric value in every step, from requisition to slide preparation. Root cause analysis was applied to the process of histology preparation to identify the root cause of each previously identified problem using Eindhoven classification. All errors were recorded on a pre-designed proforma. RESULTS: There were 2420 specimens. While errors were encountered in all phases of the pre-microscopic process, but the (G6: n=1085, 44.83%), followed by requisition (R3: n=893, 36.9%) and cover slipping (C1: n=776, 32.06%). CONCLUSIONS: Development of standard procedures and protocols with staff training is likely to help in controlling the errors.

Mass School Shootings in the United States: A Novel Root Cause Analysis Using Lay Press Reports.

School shootings comprise a small proportion of childhood deaths from firearms; however, these shootings receive a disproportionately large share of media attention. We conducted a root cause analysis of 2 recent school shootings in the United States using lay press reports. We reviewed 1760 and analyzed 282 articles from the 10 most trusted news sources. We identified 356 factors associated with the school shootings. Policy-level factors, including a paucity of adequate legislation controlling firearm purchase and ownership, were the most common contributing factors to school shootings. Mental illness was a commonly cited person-level factor, and access to firearms in the home and availability of large-capacity firearms were commonly cited environmental factors. Novel approaches, including root cause analyses using lay media, can identify factors contributing to mass shootings. The policy, person, and environmental factors associated with these school shootings should be addressed as part of a multipronged effort to prevent future mass shootings.

Causal analysis of the impact of homecare services on patient discharge disposition.

This study uses observational causal inference to evaluate the impact of different combinations of home care services (nursing, therapies, social work, home aides) on end-of-episode disposition for individuals with chronic diseases associated with the circulatory, endocrine, and musculoskeletal systems. The potential to generate actionable recommendations for personalizing home care services, or treatment plans, from limited clinical and care needs data is demonstrated. For patients with chronic disease in the circulatory or musculoskeletal systems, a 2.91% and 3.38% decrease, respectively, in acute care hospitalization rates could be obtained by providing patients with therapy and nursing services, rather than therapy services alone.

Risk factors for post-dural puncture headache following injury of the dural membrane: a root-cause analysis and nested case-control study.

BACKGROUND: Post-dural puncture headache following trauma to the dural membrane during neuraxial anaesthesia occurs in 0.13-6.5% of pregnant patients. Identifying factors beyond individual performance that contribute to this adverse event is crucial to developing improvement strategies. METHODS: We used a root cause analysis framework, in a nested case-control study, to identify associated factors. Cases were all patients who had a post-dural puncture headache requiring an epidural blood patch. These patients were matched to a random group of control patients without post-dural puncture headache or known dural injury. Mixed logistic modelling was used. RESULTS: Within a dataset of 35 763 patients, we selected all 154 patients with post-dural puncture headache and compared them with 616 controls. Migraine (odds ratio [OR] 10.60, 95% CI 2.74 to 41.05), obstetric and perinatal pathology (OR 10.85, 95% CI 4.29 to 21.42), and multiple insertion attempts (OR 11.48, 95% CI 6.29 to 20.94), increased the risk of post-dural puncture headache. In contrast, training >3 years (OR 0.20, 95% CI 0.55 to 0.76) and a nurse anaesthetist present during the procedure (OR 0.05, 95% CI 0.01 to 0.29) decreased the risk. The anaesthetist's identity, the size of the labour room, the timing of the procedure or workload did not modify the risk. CONCLUSION: Post-dural puncture headache in this setting is not the result of the individual anaesthetist's characteristics alone. Additional factors including team composition, the presence of obstetrical perinatal pathology, and associated patient's conditions, are also associated with this event. Improvement strategies should consider all these factors.

Investigating Serious Adverse Drug Reactions in Patients Receiving Erythropoiesis-Stimulating Agents: A Root Cause Analysis Using the "ANTICIPATE" Framework.

BACKGROUND: Unexpected serious adverse drug reactions (sADRs) affecting patients with chronic kidney disease (CKD) who received erythropoiesis-stimulating agents were identified by study co-authors. These included pure red cell aplasia (PRCA) after administration of the Eprex formulation of epoetin or the epoetin biosimilar HX575 and fatal anaphylaxis associated with peginesatide, an erythropoietin receptor agonist. We developed and applied a structured framework to describe these sADRs, including root cause analyses and eradication efforts. METHODS: A 10-step framework termed "ANTICIPATE," focusing on signal identification, incidence, causality, and eradication guided our evaluations. RESULTS: Initial cases were identified by a hematologist (Eprex), clinical study monitors (HX575), and 4 nurses (peginesatide). The number of persons with individual ADRs was 13 PRCA cases for epoetin, 2 antibody-mediated PRCA cases for HX575, and 5 fatal anaphylaxis cases for peginesatide. Initial incidence estimates per 1000 treated persons were 0.27 for Eprex-associated PRCA, 11 for HX575-associated PRCA, and 0.38 for peginesatide fatalities. Likely causes were subcutaneous administration of epoetin formulated with polysorbate 80 (Eprex), tungsten leaching from pins included in product syringes (HX575), and inclusion of a phenol stabilizer (peginesatide). Eradication strategies included restricting Eprex administration to the intravenous route, excluding tungsten from HX575 syringes, and for peginesatide, proposed eradication was to return to single-dose vials without preservatives. CONCLUSION: Although the number of cases of each sADR was small, eradication was successful for 2 sADRs, and a proposed eradication was developed for a third sADR. The structured framework used to describe the above 3 sADRs in patients with CKD can also be used in other clinical settings.

Errors in cervical spine immobilization during pediatric trauma evaluation.

BACKGROUND: The purpose of this study was to identify factors during trauma evaluation that increase the likelihood of errors in cervical spine immobilization ('lapses'). MATERIALS AND METHODS: Multivariate analysis was used to identify the associations between patient characteristics, event features, and tasks performed in proximity to the head and neck and the occurrence and duration of a lapse in maintaining cervical spine immobilization during 56 pediatric trauma evaluations. RESULTS: Lapses in cervical spine immobilization occurred in 71.4% of patients (n = 40), with an average of 1.2 ± 1.3 lapses per patient. Head and neck tasks classified as oxygen manipulation occurred an average of 12.2 ± 9.7 times per patient, whereas those related to neck examination and cervical collar manipulation occurred an average of 2.7 ± 1.7 and 2.1 ± 1.2 times per patient, respectively. More oxygen-related tasks were performed among patients who had than those who did not have a lapse (27.3 ± 16.5 versus 11.5 ± 8.0 tasks, P = 0.001). Patients who had cervical collar placement or manipulation had a two-fold higher risk of a lapse than those who did not have these tasks performed (OR 1.92, 95% CI 0.56, 3.28, P = 0.006). More lapses occurred during evaluations on the weekend (P = 0.01), when more tasks related to supplemental oxygen manipulation were performed (P = 0.02) and when more tasks associated with cervical collar management were performed (P < 0.001). CONCLUSIONS: Errors in cervical spine immobilization were frequently observed during the initial evaluation of injured children. Strategies to reduce these errors should target approaches to head and neck management during the primary and secondary phases of trauma evaluation.

Are root cause analyses recommendations effective and sustainable? An observational study.

OBJECTIVE: To assess the strength of root cause analysis (RCA) recommendations and their perceived levels of effectiveness and sustainability. DESIGN: All RCAs related to sentinel events (SEs) undertaken between the years 2010 and 2015 in the public health system in Victoria, Australia were analysed. The type and strength of each recommendation in the RCA reports were coded by an expert patient safety classifier using the US Department of Veteran Affairs type and strength criteria. PARTICIPANTS AND SETTING: Thirty-six public health services. MAIN OUTCOME MEASURE(S): The proportion of RCA recommendations which were classified as 'strong' (more likely to be effective and sustainable), 'medium' (possibly effective and sustainable) or 'weak' (less likely to be effective and sustainable). RESULTS: There were 227 RCAs in the period of study. In these RCAs, 1137 recommendations were made. Of these 8% were 'strong', 44% 'medium' and 48% were 'weak'. In 31 RCAs, or nearly 15%, only weak recommendations were made. In 24 (11%) RCAs five or more weak recommendations were made. In 165 (72%) RCAs no strong recommendations were made. The most frequent recommendation types were reviewing or enhancing a policy/guideline/documentation, and training and education. CONCLUSIONS: Only a small proportion of recommendations arising from RCAs in Victoria are 'strong'. This suggests that insights from the majority of RCAs are not likely to inform practice or process improvements. Suggested improvements include more human factors expertise and independence in investigations, more extensive application of existing tools that assist teams to prioritize recommendations that are likely to be effective, and greater use of observational and simulation techniques to understand the underlying systems factors. Time spent in repeatedly investigating similar incidents may be better spent aggregating and thematically analysing existing sources of information about patient safety.

Adverse events occurring on mental health units.

OBJECTIVE: While the study of suicide on mental health units has a long history, the study of patient safety more generally is relatively new. Our objective was to determine the type and relative frequency of adverse events occurring on Veterans Health Administration (VHA) mental health units; the primary root causes for these events; and make recommendations for abating or mitigating these events. METHODS: We searched our national database for any reported adverse event that occurred on an inpatient mental health unit between January 1, 2015 and December 31, 2016. We found 87 Root Cause Analysis (RCA) reports and 9780 safety reports. The safety reports were coded for type of event and the RCAs were further coded for underlying causes and severity. RESULTS: Of the 87 RCA reports, there were 31suicide attempts, 16 elopements, 10 assaults, 8 events involving hazardous items on the unit, 7 falls, 6 unexpected deaths, 3 overdoses and 6 cases coded as "other". For the 9780 safety reports falls were the most common event, followed by medication events, verbal assaults, physical assaults, medical problems and hazardous items on the unit. CONCLUSIONS: As with medical units, patients on mental health units are at risk for many types of adverse events. The same focus on patient safety is just as important for our mental health patients as for our medical patients. Mental health unit staff should undertake a structured assessment of all risk on their units. This broad approach may be more successful than focusing on a particular event type.

Pediatric surgery readmissions: a root cause analysis.

INTRODUCTION: Hospital readmission rates are used as a metric of the quality of patient care in adults. Readmission data is lacking for pediatric surgical patients. The objective of this study is to evaluate our institution's 30-day unexpected pediatric surgical readmission data to identify potentially preventable readmissions. METHODS: An internal database of all pediatric surgical 30-day readmissions to two tertiary-referral children's hospitals in a single health system was reviewed. All pediatric general surgery admissions between January 2008 and May 2013 with hospital readmission within 30 days were included in the study. Patient demographics, diagnoses, cause of readmission, procedure performed, and length of stay were recorded. Charts were individually reviewed to evaluate causality of readmission. RESULTS: There were 2217 pediatric general surgery admissions during the study period. Of these, 145 (6.5%) experienced unexpected readmission within 30 days. One-third of all readmissions occurred in infants between 0 and 364 days of age, 50% occurred in those under 2 years and wholly 80% of all readmissions occurred in those under 9 years of age. A majority of readmissions were associated with chronic comorbid conditions. CONCLUSION: Analysis of pediatric surgical readmission data may assist hospitals in focusing quality of care and cost effectiveness strategies. Development of coordination of care strategies and discharge planning involving both pediatric surgical teams and pediatric hospitalists/specialists may reduce pediatric surgical readmission rates.

A cross-sectional study on the relationship between utilization of root cause analysis and patient safety at 139 Department of Veterans Affairs medical centers.

BACKGROUND: Empirical evidence is limited that root cause analysis (RCA), an event analysis tool used in health care to evaluate the systemic factors that lead to adverse events, improves patient safety. A cross-sectional study was conducted to examine the relationship between RCA and patient safety. METHODS: RCA data were collected for the 139 Department of Veteran Affairs medical centers (VAMCs) in the National Center for Patient Safety database from 2004 through 2006. Participants were divided into three RCA utilization categories on the basis of their yearly RCA rate: (1) fewer than 4 RCAs, (2) 4 to 5 RCAs, and (3) 6 or more RCAs per year. An analysis of variance was conducted of each Agency for Healthcare Research and Quality Patient Safety Indicators (PSIs) across the three RCA utilization categories. RESULTS: Facilities completed between 3 and 59 RCAs in the three-year period (mean RCA utilization rate, 4.86 RCAs per year). In this period, RCA actions by facility ranged from 9 to 323 (mean, 28 actions per year per facility). Mean patient-days of care, facility budget, surgical volume, and the number of strong improvement actions were significantly different across RCA utilization categories. The mean rates of PSI 9 (Postoperative Hemorrhage or Hematoma), PSI 10 (Postoperative Physiologic and Metabolic Derangements), and PSI 13 (Postoperative Sepsis) were significantly different across RCA utilization categories. CONCLUSIONS: Large, high-spending VAMCs conduct more RCAs per year than smaller, low-spending facilities. VAMCs that do more RCAs develop more corrective actions. VAMCs that complete fewer than four RCAs per year have higher rates of postoperative complications. It is unclear if RCAs are associated with a functional patient safety program or directly improve patient safety.

Mortalidad neonatal: análisis causa raíz: estudio prospectivo de los factores vinculados a la muerte de recién nacidos internados en maternidades seleccionadas del sector público de la República Argentina / Neonatal mortality: root cause analysis: prospective study of factors related to the death of newborns admitted to selected maternity of the public sector of Argentina

Objetivo: identificar y caracterizar a los RN que fallecen en 5 principales maternidades públicas y explorar factores relacionados a las muertes reducibles a través del análisis de Causa Raíz (ACR). Métodos: Estudio prospectivo multicéntrico, descriptivo y observacional. Estrategia cuantitativa de corte transversal y cualitativa tipo ACR. Resultados: durante 10 meses se produjeron 238 muertes neonatales sobre 22.324 nacimientos más 651 RN derivados (TM global 10,35‰). La media de PN de los fallecidos fue 1838 ± 999 g y la mediana 1635 g (1000-2650) y la de edad gestacional 32 ± 5 sem. La edad materna fue de 25 ± 7años y sólo el 20% no tuvo ningún control en su embarazo. Las principales causas de internación fueron dificultad respiratoria (42%), malformaciones (39%), infecciones y asfixia perinatal. El 65% presentó alguna complicación en la evolución. La principal causa de muerte fueron las malformaciones congénitas (38%) seguida por la infección intrahospitalaria (27%). Con respecto al ACR la dimensión institucional (coordinación de la atención, experiencia, capacitación, infección hospitalaria) estuvo vinculada a 48% de las muertes mientras que la dimensión RRHH fue la más frecuentemente reconocida como deficitaria y relacionada con el evento muerte (57%). El 56,7% de las muertes fueron clasificadas como potencialmente reducibles, oscilando entre 35,5% y 76,2% según los centros. Conclusiones: La mayor parte de las muertes neonatales analizadas parecen reducibles. Dentro de las medidas preventivas necesarias a nivel de los sistemas y procesos, resulta fundamental establecer estrategias de capacitación y fortalecimiento del recurso humano que asiste a esta población vulnerable.
