Systems of Care Factors Should Be Considered in Regionalization of Congenital Cardiac Surgery.

BACKGROUND: Regionalization of care has been proposed to optimize outcomes in congenital cardiac surgery (CCS). We hypothesized that hospital infrastructure and systems of care factors could also be considered in regionalization efforts. METHODS: Observed-to-expected (O/E) mortality ratio and hospital volumes were obtained between 2015 and 2018 from public reporting data. Using a resource dependence framework, we examined factors obtained from American Hospital Association, Children's Hospital Association, and hospital websites. Linear regression models were estimated with volume only, then with hospital factors, stratified by procedural complexity. Robust regression models were reestimated to assess the impact of outliers. RESULTS: We found wide variation in the volume of congenital cardiac surgeries performed (89-3920) and in the surgical outcomes (O/E ratio range, 0.3-3.1). Six outlier hospitals performed few high-complexity cases with high mortality. Univariate analysis including all cases indicated that higher volume predicted lower O/E ratio (ß = -0.02; SE = 0.008; P = .011). However, this effect was driven by the most complex cases. Models stratified by The Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery category show that volume is a significant predictor only in category 5 cases (ß = -1.707; SE = 0.663; P = .012). Robust univariate regression accounting for outliers found no effect of volume on O/E ratio (ß = 0.005; SE = 0.002; P = .975). Elimination of outliers through robust multivariate regression decreased the volume-outcome relationship and found a modest relationship between health plan ownership and outcomes. CONCLUSIONS: Systems of care factors should be considered in addition to volume in designing regionalization in CCS. Patient-level data sets will better define these factors.

A Statewide Approach to Reducing Re-excision Rates for Women With Breast-conserving Surgery.

OBJECTIVE: Test the effectiveness of benchmarked performance reports based on existing discharge data paired with a statewide intervention to implement evidence-based strategies on breast re-excision rates. BACKGROUND: Breast-conserving surgery (BCS) is a common breast cancer surgery performed in a range of hospital settings. Studies have demonstrated variations in post-BCS re-excision rates, identifying it as a high-value improvement target. METHODS: Wisconsin Hospital Association discharge data (2017-2019) were used to compare 60-day re-excision rates following BCS for breast cancer. The analysis estimated the difference in the average change preintervention to postintervention between Surgical Collaborative of Wisconsin (SCW) and nonparticipating hospitals using a logistic mixed-effects model with repeated measures, adjusting for age, payer, and hospital volume, including hospitals as random effects. The intervention included 5 collaborative meetings in 2018 to 2019 where surgeon champions shared guideline updates, best practices/challenges, and facilitated action planning. Confidential benchmarked performance reports were provided. RESULTS: In 2017, there were 3692 breast procedures in SCW and 1279 in nonparticipating hospitals; hospital-level re-excision rates ranged from 5% to >50%. There was no statistically significant baseline difference in re-excision rates between SCW and nonparticipating hospitals (16.1% vs. 17.1%, P =0.47). Re-excision significantly decreased for SCW but not for nonparticipating hospitals (odds ratio=0.69, 95% confidence interval=0.52-0.91). CONCLUSIONS: Benchmarked performance reports and collaborative quality improvement can decrease post-BCS re-excisions, increase quality, and decrease costs. Our study demonstrates the effective use of administrative data as a platform for statewide quality collaboratives. Using existing data requires fewer resources and offers a new paradigm that promotes participation across practice settings.

Driving Time to Trauma Centers for Children Living in Wisconsin.

INTRODUCTION: Trauma is the number 1 cause of death among children. Shorter distance to definitive trauma care has been correlated with better clinical outcomes. There are only a small number of pediatric trauma centers (PTC) designated by the American College of Surgeons, and the resources available to treat injured children at non-PTCs are limited. To guide resource allocation and advocacy efforts for pediatric trauma care in Wisconsin, we determined the precise distance to trauma centers for all children living in the state. METHODS: The 2010 US Census data was used to determine ZIP-centroid geolocation. The Wisconsin Department of Health Services trauma classification database was used to identify trauma facilities in Wisconsin. SAS routines invoking the Google Maps application programming interface were used to calculate the driving distance to each of the trauma facilities. We quantified the percentage of children living within 30- and 60-minute driving distances of level I-IV trauma centers. RESULTS: Just 31.3% of Wisconsin children live within a 30-minute drive of a level I PTC; 32.7% live within 30 minutes of a level II center; 81.3% within 30 minutes of a level III center; and 74.6% within 30 minutes of a level IV center. CONCLUSION: Two-thirds of children in Wisconsin live beyond a 30-minute driving distance of a level I PTC, but most children live within 30 minutes of level III and IV trauma centers. As the closest hospitals for most children, smaller trauma centers should be adequately resourced to provide pediatric trauma care.

Opioid prescribing to preteen children undergoing ambulatory surgery in the United States.

BACKGROUND: Overuse and misuse of opioids is a continuing crisis. The most common reason for children to receive opioids is postoperative pain, and they are often prescribed more than needed. The amount of opioids prescribed varies widely, even for minor ambulatory procedures. This study uses a large national sample to describe filled opioid prescriptions to preteen patients after all ambulatory surgical procedures and common standard procedures. METHODS: We analyzed Truven Health MarketScan data for July 2012 through December 2016 to perform descriptive analyses of opioid fills by age and geographic area, change over time, second opioid fills in opioid-naïve patients, and variation in the types and amount of medication prescribed for 18 common and standard procedures in otolaryngology, urology, general surgery, ophthalmology, and orthopedics. RESULTS: Over 10% of preteen children filled perioperative opioid prescriptions for ambulatory surgery in the period 2012 to 2016. The amount prescribed varied widely (median 5 days' supply, IQR 3-8, range 1-90), even for the most minor procedures, for example, frenotomy (median 4 days' supply, IQR 2-5, range 1-60). Codeine fills were common despite safety concerns. Second opioid prescriptions were filled by opioid-naïve patients after almost all procedures studied. The rate of prescribing declined significantly over time and varied substantially by age and across census regions. CONCLUSIONS: We identified opioid prescribing outside of the norms of standard practice in all of the specialties studied. Standardizing perioperative opioid prescribing and developing guidelines on appropriate prescribing for children may reduce the opioids available for misuse and diversion.

Medication Safety in Two Intensive Care Units of a Community Teaching Hospital After Electronic Health Record Implementation: Sociotechnical and Human Factors Engineering Considerations.

OBJECTIVE: The aim of the study was to assess the impact of Electronic Health Record (EHR) implementation on medication safety in two intensive care units (ICUs). METHODS: Using a prospective pre-post design, we assessed 1254 consecutive admissions to two ICUs before and after an EHR implementation. Each medication event was evaluated with regard to medication error (error type, medication-management stage) and impact on patient (severity of potential or actual harm). RESULTS: We identified 4063 medication-related events either pre-implementation (2074 events) or post-implementation (1989 events). Although the overall potential for harm due to medication errors decreased post-implementation only 2 of the 3 error rates were significantly lower post-implementation. After EHR implementation, we observed reductions in rates of medication errors per admission at the stages of transcription (0.13-0, P < 0.001), dispensing (0.49-0.16, P < 0.001), and administration (0.83-0.56, P = 0.011). Within the ordering stage, 4 error types decreased post-implementation (orders with omitted information, error-prone abbreviations, illegible orders, failure to renew orders) and 4 error types increased post-implementation (orders of wrong drug, orders containing a wrong start or stop time, duplicate orders, orders with inappropriate or wrong information). Within the administration stage, we observed a reduction of late administrations and increases in omitted administrations and incorrect documentation. CONCLUSIONS: Electronic Health Record implementation in two ICUs was associated with both improvement and worsening in rates of specific error types. Further safety improvements require a nuanced understanding of how various error types are influenced by the technology and the sociotechnical work system of the technology implementation. Recommendations based on human factors engineering principles are provided for reducing medication errors.

Continued Prescribing of Periprocedural Codeine and Tramadol to Children after a Black Box Warning.

BACKGROUND: Codeine and tramadol are commonly used analgesics in surgery. In 2013, the Food and Drug Administration (FDA) issued a contraindication to the use of codeine in tonsillectomy and adenoidectomy patients aged below 18 y. This warning was expanded in April 2017 to include tramadol and all children aged below 12 y. We sought to describe the prescribing of codeine and tramadol to contraindicated populations in Wisconsin before and after the release of the expanded FDA warning. MATERIALS AND METHODS: Using a statewide Wisconsin claims database, we identified common pediatric ambulatory surgical procedures across the specialties of otolaryngology, urology, general surgery, orthopedics, and ophthalmology. For these procedures, we examined the rates of perioperative codeine and tramadol prescription fills and change in prescribing after the FDA contraindication. RESULTS: Surgeons in all of the specialties studied continued to prescribe codeine to pediatric patients after the contraindication, but tramadol was rarely prescribed. Procedures with relatively high rates of codeine fills were strabismus repair (65% of opioid fills), circumcision >1 yo (22%), and laparoscopic appendectomy (15%). Codeine fills significantly declined after the contraindication to 6% for circumcision >1 yo and 5% for orchiopexy and inguinal hernia repair. Otolaryngology, which was subject to the 2013 codeine contraindication, has low rates of codeine fills (under 2.5%) for the whole period studied. Codeine prescribing for strabismus repair showed no significant decline. CONCLUSIONS: Codeine, and to a lesser extent tramadol, continue to be prescribed to contraindicated populations of children. This represents a target for future de-implementation interventions.

Age-Dependent Costs and Complications in Pediatric Umbilical Hernia Repair.

OBJECTIVES: To characterize regional variation in the age of patients undergoing umbilical hernia repair to determine costs and subsequent care. STUDY DESIGN: We performed a cross-sectional descriptive study using a large convenience sample of US employer-based insurance claims from July 2012 to December 2015. We identified children younger than 18 years of age undergoing uncomplicated (not strangulated, incarcerated, or gangrenous) umbilical hernia repair as an isolated procedure (International Classification of Diseases, Ninth Revision procedure codes 53.41, 53.42, 53.43, or 53.49, International Classification of Diseases, Tenth Revision procedure code 0WQF0ZZ, or Current Procedural Terminology procedure codes 49580 or 49585). RESULTS: In all, 5212 children met criteria for inclusion. Children younger than age 2 years accounted for 9.7% of repairs, with significant variation by census region (6% to 14%, P < .001). Total payments for surgery varied by age; children younger than 2 years averaged $8219 and payments for older children were $6137. Postoperative admissions occurred at a rate of 73.1 per 1000 for children younger than age 2 years and 7.43 for older children; emergency department visits were 41.5 per 1000 for children younger than age 2 years vs 15.9 for older children (P < .001). CONCLUSIONS: Umbilical hernias continue to be repaired at early ages with large regional variation. Umbilical hernia repair younger than age 2 years is associated with greater costs and greater frequency of postoperative hospitalization and emergency department visits.

System Factors Influencing the Use of a Family-Centered Rounds Checklist.

INTRODUCTION: Checklists are used to operationalize care processes and enhance patient safety; however, checklist implementation is difficult within complex health systems. A family-centered rounds (FCR) checklist increased physician performance of key rounding activities, which were associated with improved parent engagement, safety perceptions, and behaviors. To inform FCR checklist implementation and dissemination, we assessed physician compliance with this checklist and factors influencing its use. METHODS: Guided by a recognized human factors and systems engineering approach, rounding observations and ad hoc resident and attending physician interviews were conducted at a tertiary children's hospital. Rounding observers documented 8-item checklist completion (nurse presence, family preference, introductions, assessment/plan, discharge goals, care team questions, family questions, and read back orders) and then interviewed physicians to elicit their perceptions of challenges and facilitators to FCR checklist use. We performed a directed content analysis of interview notes, iteratively categorizing data into known hospital work system components. RESULTS: Of 88 individual patient rounds observed after checklist implementation, 90% included the nurse, and 77% occurred at the bedside. In an average patient rounding session, staff performed 82% of checklist items. Factors influencing checklist use were related to all hospital work system components, eg, physician familiarity with checklist content (people), visibility of the checklist (environment), providing schedules for rounding participants (organization), and availability of a mobile computer during rounds (technology). CONCLUSIONS: Multiple factors within hospital systems may influence FCR checklist use. Strategies, such as providing rounding schedules and mobile computers, may promote optimal engagement of families during rounds and promote pediatric patient safety.

Diagnostic performance of standardized ultrasound protocol for detecting perforation in pediatric appendicitis.

BACKGROUND: Recent clinical trials in adults and children have shown that uncomplicated acute appendicitis can be successfully treated with antibiotics alone. As treatment strategies for acute appendicitis diverge, accurate preoperative diagnosis of complicated appendicitis and appendiceal perforation has become increasingly important for clinical decision-making. OBJECTIVE: To examine diagnostic performance of ultrasound for detecting perforated appendicitis in a single institution using a standardized technique. MATERIALS AND METHODS: In this retrospective single-center study we evaluated 113 ultrasounds from pediatric patients who underwent appendectomy between November 2014 and December 2015. All ultrasounds were performed using a standardized US protocol including still and cine images of all four abdominal quadrants, with more targeted evaluation of the right lower quadrant (RLQ) using graded compression technique. We compared US findings to intraoperative diagnosis of non-perforated or perforated acute appendicitis. RESULTS: The standardized image protocol generated a reproducible set of ultrasound images in all cases. The most common primary appendiceal finding on US in perforated appendicitis was appendix wall thickening >3 mm (54%, 171/314) and most common secondary finding was echogenic mesenteric fat (75%, 237/314). Thinning of the appendix wall and loculated fluid collection in the right lower quadrant were both highly specific (>90%) for perforation. CONCLUSION: The diagnostic performance of ultrasound using a standardized US technique was similar to that reported in prior studies for detecting perforated appendicitis. Despite low sensitivity, individual ultrasound findings and overall diagnostic impression of "evidence of appendix perforation" remain highly specific.

Practice Variation in Umbilical Hernia Repair Demonstrates a Need for Best Practice Guidelines.

OBJECTIVE: To evaluate and better understand variations in practice patterns, we analyzed ambulatory surgery claims data from 3 demographically diverse states to assess the relationship between age at umbilical hernia repair and patient, hospital, and geographic characteristics. STUDY DESIGN: We performed a cross-sectional descriptive study of uncomplicated hernia repairs performed as a single procedure in 2012-2014, using the State Ambulatory Surgery and Services Database for Wisconsin, New York, and Florida. Age and demographic characteristics of umbilical hernia repair patients are described. RESULTS: The State Ambulatory Surgery and Services Database analysis included 6551 patients. Across 3 states, 8.2% of hernia repairs were performed in children <2 years, 18.7% in children age 2-3 years, and 73.0% in children age ≥4 years, but there was significant variability (P < .001) in practice patterns by state. In regression analysis, race, Medicaid insurance and rural residence were predictive of early repair, with African American patients less likely to have a repair before age 2 (OR 0.62, P = .046) and rural children (OR 1.53, P = .009) and Medicaid patients (OR 2.01, P < .001) more likely to do so. State of residence predicted early repair even when holding these variables constant. CONCLUSIONS: The age of pediatric umbilical hernia repair varies widely. As hernias may resolve over time and can be safely monitored with watchful waiting, formal guidelines are needed to support delayed repair and prevent unnecessary operations.

Age-dependent outcomes in asymptomatic umbilical hernia repair.

PURPOSE: Umbilical hernias are common in young children. Many resolve spontaneously by age four with very low risk of symptoms or incarceration. Complications associated with surgical repair of asymptomatic umbilical hernias have not been well elucidated. We analyzed data from one hospital to test the hypothesis that repair at younger ages is associated with increased complication rates. METHODS: A retrospective chart review of all umbilical hernia repairs performed during 2007-2015 was conducted at a tertiary care children's hospital. Patients undergoing repairs as a single procedure for asymptomatic hernia were evaluated for post-operative complications by age, demographics, and co-morbidities. RESULTS: Of 308 umbilical hernia repairs performed, 204 were isolated and asymptomatic. Postoperative complications were more frequent in children < 4 years (12.3%) compared to > 4 years (3.1%, p = 0.034). All respiratory complications (N = 4) and readmissions (N = 1) were in children < 4 years. CONCLUSIONS: Age of umbilical hernia repair in children varied widely even within a single institution, demonstrating that timing of repair may be a surgeon-dependent decision. Patients < 4 years were more likely to experience post-operative complications. Umbilical hernias often resolve over time and can safely be monitored with watchful waiting. Formal guidelines are needed to support delayed repair and prevent unnecessary, potentially harmful operations.

National variation in opioid prescribing after pediatric umbilical hernia repair.

BACKGROUND: Pediatric umbilical hernia repair is a common procedure that requires minimal tissue disruption. We examined variation in opioid prescription fills after repair of uncomplicated umbilical hernias to characterize the types and doses of medication used and persistent postsurgical use. METHODS: Using the Truven Health Analytics MarketScan© Research Database for June 2012-September 2015, we identified pediatric patients undergoing umbilical hernia repair. We excluded patients with obstruction, gangrene, an earlier repair or a concurrent surgical procedure, and those without available pharmacy claim data. Analyses describe filled outpatient prescriptions by age, geographic region, drug type, quantity, and second prescriptions/refills. RESULTS: Of 4,407 procedures performed, 2,292 patients (52%) filled a prescription for postoperative opioids (age 0-1 years: 21.6%, age 2-3 years: 51.5%, age 4-5 years: 54.3%, 6 years or older: 57.9% [P < .0001]). In the northeast United States, 42% of patients filled narcotic prescriptions, compared with 59% of patients in the south (P < .0001). Hydrocodone/acetaminophen was most commonly prescribed (51%), followed by codeine/acetaminophen (30%). Durations were ≤3 days (50%), 4-10 days (46%), and >10 days (4%). A total of 6% of patients filled a second opioid prescription within 30 days. CONCLUSION: Although many patients do not require opioids for umbilical hernia repair, most pediatric patients fill opioid prescriptions, including for prolonged courses and refills. Guidelines for appropriate prescribing of opioids after common, simple procedures, such as umbilical hernia repair, could improve the quality of care for children and impact the US epidemic of opioid abuse.

Management of asymptomatic pediatric umbilical hernias: a systematic review.

INTRODUCTION: Uncomplicated pediatric umbilical hernias are common and most close spontaneously. No formal practice guidelines exist regarding the optimal timing and indications for repair. The objective of this review is to examine the existing literature on the natural history of pediatric umbilical hernias, known complications of repair and non-operative approaches, and management recommendations. STUDY DESIGN: A systematic literature search was performed to identify publications relating to pediatric umbilical hernias. Inclusion criteria comprised studies addressing recommendations for optimal timing of repair, evidence examining complications from hernias not operatively repaired, and research exploring the likelihood of pediatric umbilical hernias to close spontaneously. In addition, the websites of all pediatric hospitals in the United States were examined for recommendations on operative timing. RESULTS: A total of 787 manuscripts were reviewed, and 28 met criteria for inclusion in the analysis. Studies examined the likelihood of spontaneous closure based on child's age and size of hernia defect, complications of unrepaired umbilical hernias including incarceration, strangulation and evisceration based on child's age and size of defect, incidence of postoperative complications and current recommendations for timing of repair. In addition, 63 (27.5%) of the United States pediatric hospital websites published a wide range of management recommendations. CONCLUSION: Despite the high prevalence of pediatric umbilical hernias, there is a paucity of high quality data to guide management. The literature does suggest that expectant management of asymptomatic hernias until age 4-5years, regardless of size of hernia defect, is both safe and the standard practice of many pediatric hospitals. TYPE OF STUDY: Review Article. LEVEL OF EVIDENCE: Level IV.

The impact of secure messaging on workflow in primary care: Results of a multiple-case, multiple-method study.

INTRODUCTION: Secure messaging is a relatively new addition to health information technology (IT). Several studies have examined the impact of secure messaging on (clinical) outcomes but very few studies have examined the impact on workflow in primary care clinics. In this study we examined the impact of secure messaging on workflow of clinicians, staff and patients. METHODS: We used a multiple case study design with multiple data collections methods (observation, interviews and survey). RESULTS: Results show that secure messaging has the potential to improve communication and information flow and the organization of work in primary care clinics, partly due to the possibility of asynchronous communication. However, secure messaging can also have a negative effect on communication and increase workload, especially if patients send messages that are not appropriate for the secure messaging medium (for example, messages that are too long, complex, ambiguous, or inappropriate). Results show that clinicians are ambivalent about secure messaging. Secure messaging can add to their workload, especially if there is high message volume, and currently they are not compensated for these activities. Staff is -especially compared to clinicians- relatively positive about secure messaging and patients are overall very satisfied with secure messaging. Finally, clinicians, staff and patients think that secure messaging can have a positive effect on quality of care and patient safety. CONCLUSION: Secure messaging is a tool that has the potential to improve communication and information flow. However, the potential of secure messaging to improve workflow is dependent on the way it is implemented and used.

EHR-related medication errors in two ICUs.

The objective of this study was to describe the frequency, potential harm, and nature of electronic health record (EHR)-related medication errors in intensive care units (ICUs). Using a secondary data analysis of a large database of medication safety events collected in a study on EHR technology in ICUs, we assessed the EHR relatedness of a total of 1622 potential preventable adverse drug events (ADEs) identified in a sample of 624 patients in 2 ICUs of a medical center. Thirty-four percent of the medication events were found to be EHR related. The EHR-related medication events had greater potential for more serious patient harm and occurred more frequently at the ordering stage as compared to non-EHR-related events. Examples of EHR-related events included orders with omitted information and duplicate orders. The list of EHR-related medication errors can be used by health care delivery organizations to monitor implementation and use of the technology and its impact on patient safety. Health information technology (IT) vendors can use the list to examine whether their technology can mitigate or reduce EHR-related medication errors.

Perceived Impact of Care Managers' Work on Patient and Clinician Outcomes.

OBJECTIVES: The aim of this study is to assess the contributions of care management as perceived by care managers themselves. STUDY DESIGN: Focus groups and interviews with care managers who coordinate care for chronic obstructive pulmonary disease and congestive heart failure patients, as well as patients undergoing major surgery. METHODS: We collected data in focus groups and interviews with 12 care managers working in the Keystone Beacon Community project, including 5 care managers working in hospitals, 2 employed in outpatient clinics and 4 telephoning discharged patients from a Transitions of Care (TOC) call center. RESULTS: Inpatient care managers believe that (1) ensuring primary care provider follow-up, (2) coordinating appropriate services, (3) providing patient education, and (4) ensuring accurate medication reconciliation have the greatest impact on patient clinical outcomes. In contrast, outpatient and TOC care managers believe that (1) teaching patients the signs and symptoms of acute exacerbations and (2) building effective relationships with patients improve patient outcomes most. Some care management activities were perceived to have greater impact on patients with certain conditions (e.g., outpatient and TOC care managers saw effective relationships as having more impact on patients with COPD). All care managers believed that relationships with patients have the greatest impact on patient satisfaction, while the support they provide clinicians has the greatest impact on clinician satisfaction. CONCLUSIONS: These findings may improve best practice for care managers by focusing interventions on the most effective activities for patients with specific medical conditions.

How Do Residents Spend Their Time in the Intensive Care Unit?

PURPOSE: To describe the work of residents and the distribution of their time in 6 intensive care units (ICUs) of 2 medical centers (MCs). METHODS: A total of 242 hours of observation to capture data on tasks performed by residents in 6 ICUs, including adult, pediatric, medical and surgical units, were conducted. For each observation period, the percentages of total time spent on each task and on the aggregated task categories were calculated. RESULTS: Overall, while in the ICUs, residents spent almost half of their time in clinical review and documentation (19%), conversation with team physicians (16%), conversation attendance (6%) and order management (6%). The 2 MCs differed in the time that residents spent on administrative review and documentation (4% in one MC and 15% in the other). The pediatric ICUs were similar in the 2 MCs, whereas the adult ICUs exhibited differences in the time spent on order management and administrative review and documentation. CONCLUSIONS: While in the ICUs, residents spent most time performing direct patient care and care coordination activities. The distribution of activities varied across 2 MCs and across ICUs, which highlights the need to consider the local context on residents' work in ICUs.

Impact of electronic health record technology on the work and workflow of physicians in the intensive care unit.

OBJECTIVE: To assess the impact of EHR technology on the work and workflow of ICU physicians and compare time spent by ICU resident and attending physicians on various tasks before and after EHR implementation. DESIGN: EHR technology with electronic order management (CPOE, medication administration and pharmacy system) and physician documentation was implemented in October 2007. MEASUREMENT: We collected a total of 289 h of observation pre- and post-EHR implementation. We directly observed the work of residents in three ICUs (adult medical/surgical ICU, pediatric ICU and neonatal ICU) and attending physicians in one ICU (adult medical/surgical ICU). RESULTS: EHR implementation had an impact on the time distribution of tasks as well as the temporal patterns of tasks. After EHR implementation, both residents and attending physicians spent more of their time on clinical review and documentation (40% and 55% increases, respectively). EHR implementation also affected the frequency of switching between tasks, which increased for residents (from 117 to 154 tasks per hour) but decreased for attendings (from 138 to 106 tasks per hour), and the temporal flow of tasks, in particular around what tasks occurred before and after clinical review and documentation. No changes in the time spent in conversational tasks or the physical care of the patient were observed. CONCLUSIONS: The use of EHR technology has a major impact on ICU physician work (e.g., increased time spent on clinical review and documentation) and workflow (e.g., clinical review and documentation becoming the focal point of many other tasks). Further studies should evaluate the impact of changes in physician work on the quality of care provided.
