Engaging the Front Line: Tapping into Hospital-Wide Quality and Safety Initiatives.

Healthcare increasingly is moving from volume- to value-based care, with an emphasis on linking a larger percentage of payments to the quality of care provided. There is a renewed interest in designing a focused, strategic approach to quality and safety education and engagement of trainees in hospital-wide quality, safety, and patient experience initiatives. Hospitals, trainees, and patients benefit as a result of engaging frontline learners in these activities. Hospitals can leverage the intelligence from the front line to contribute to improved hospital safety, increased employee and patient engagement, and better identification of vulnerable areas of safety risks. Trainees benefit from increased engagement by acquiring fundamentals in quality and safety; are able to satisfy Clinical Learning Environment Review recommendations; have an opportunity to practice a number of skill sets (leadership, communication, collaboration); and complete quality and safety hands-on projects. Patients benefit from a more engaged work force, safer environment for their healthcare, and an improved overall experience. In this article, the current state of the Johns Hopkins Department of Anesthesiology and Critical Care Medicine's efforts to engage its front line in quality, safety, and patient experience initiatives that are in evolutionary phases of implementation is presented. Evolutionary concepts relate to the Johns Hopkins Health System and the aim of its training program to continuously improve and innovate.

Society of Anesthesia and Sleep Medicine Guidelines on Preoperative Screening and Assessment of Adult Patients With Obstructive Sleep Apnea.

The purpose of the Society of Anesthesia and Sleep Medicine guideline on preoperative screening and assessment of adult patients with obstructive sleep apnea (OSA) is to present recommendations based on the available clinical evidence on the topic where possible. As very few well-performed randomized studies in this field of perioperative care are available, most of the recommendations were developed by experts in the field through consensus processes involving utilization of evidence grading to indicate the level of evidence upon which recommendations were based. This guideline may not be appropriate for all clinical situations and all patients. The decision whether to follow these recommendations must be made by a responsible physician on an individual basis. Protocols should be developed by individual institutions taking into account the patients' conditions, extent of interventions and available resources. This practice guideline is not intended to define standards of care or represent absolute requirements for patient care. The adherence to these guidelines cannot in any way guarantee successful outcomes and is rather meant to help individuals and institutions formulate plans to better deal with the challenges posed by perioperative patients with OSA. These recommendations reflect the current state of knowledge and its interpretation by a group of experts in the field at the time of publication. While these guidelines will be periodically updated, new information that becomes available between updates should be taken into account. Deviations in practice from guidelines may be justifiable and such deviations should not be interpreted as a basis for claims of negligence.

Burden incurred by patients and their caregivers after outpatient surgery: a prospective observational study.

INTRODUCTION: The burden of patients and their caregivers after outpatient surgery has not been fully examined. The number of outpatient surgeries has dramatically increased in the last several years, particularly in the orthopaedic sector. Patients undergoing outpatient orthopaedic procedures may be expected to have more postdischarge pain than those undergoing nonorthopaedic outpatient procedures. In light of this, assessment of patient and caregiver expectations and actual burden after discharge is of importance. QUESTIONS/PURPOSES: We assessed the impact of outpatient surgery on recovery of patients and their caregivers in the postoperative period by determining (1) expected versus actual time to resume daily activities, including work; (2) expected versus actual recovery at 7 and 30 days postoperatively; and (3) the number of caregivers that felt emotional or physical disturbances from caring for outpatients. METHODS: Forty-four adult patients undergoing outpatient surgical procedures and their primary caregivers were enrolled in this prospective survey study, of which 30% were orthopaedic patients. Surveys assessing postoperative recovery were given to patients at six time points, on Postoperative Days 0 to 3, 7, and 30. Surveys assessing the burden of informal caregiving were given to each patient's primary caregiver at four time points, on Postoperative Days 1 to 3 and 7. The enrollment rate was 79% (44 enrolled of 56 approached) and the survey response rate was 100% for patients and 93% (41 of 44) for caregivers. RESULTS: We found that 16 of 44 patients (36%) needed more time than originally anticipated to resume their daily activities and three of 29 patients (10%) needed more time off from work than originally anticipated. Patients were approximately 66% and 88% fully recovered 7 and 30 days after surgery, respectively. The primary caregivers noted disturbances in emotional (nine of 43, 21%) and physical (17 of 43, 40%) aspects of their daily lives while providing care for patients. Our surveyed patients were from multiple surgical services; however, our results may be generalized to an orthopaedic population, although they may underestimate actual results for this population given their generally higher pain scores. CONCLUSIONS: Patients may take longer to recover from outpatient surgery than previously recognized. As increased pain and prolonged recovery may be associated with increased caregiver burden, these data are of particular significance to the outpatient orthopaedic surgical population. Informal caregiving after outpatient surgery may be an unrecognized physical and psychologic burden and may have a significant societal impact. LEVEL OF EVIDENCE: Level II, prognostic study.

Past history of skin infection and risk of surgical site infection after elective surgery.

OBJECTIVE: To identify baseline patient characteristics associated with increased susceptibility to surgical site infection (SSI) after elective surgery. BACKGROUND: The Center for Medicare and Medicaid Services considers SSI to be preventable through adherence to current infection control practices; however, the etiology of wound infection is incompletely understood. METHODS: Prospective cohort study involving patients undergoing cardiac, vascular, craniotomy, and spinal surgery at 2 academic medical centers in Baltimore, MD. A comprehensive medical history was obtained at baseline, and participants were followed for 6 months using active inpatient and outpatient surveillance for deep SSI and infectious death. Infection control best practices were monitored perioperatively. The relative risk of SSI/infectious death was determined comparing those with versus those without a past medical history of skin infection using Cox proportional hazards models. RESULTS: Of 613 patients (mean [SD] = 62.3 [11.5] years; 42.1% women), 22.0% reported a history of skin infection. The cumulative incidence of deep SSI/infectious death was 6.7% versus 3.1% for those with and without a history of skin infection, respectively (unadjusted hazard ratio (HR) = 2.25; 95% confidence interval (95% CI), 0.98-5.14; P = 0.055). Risk estimates increased after adjustments for demographic and socioeconomic variables (HR = 2.82; 95% CI, 1.18-6.74; P = 0.019) and after propensity score adjustment for all potential confounders (HR = 3.41; 95% CI, 1.36-8.59; P = 0.009). Adjustments for intraoperative infection risk factors and adherence to infection control best practice metrics had no impact on risk estimates. CONCLUSIONS: A history of skin infection identified a state of enhanced susceptibility to SSI at baseline that is independent of traditional SSI risk factors and adherence to current infection control practices.

Wrong-Patient Blood Transfusion Error: Leveraging Technology to Overcome Human Error in Intraoperative Blood Component Administration.

BACKGROUND: Confirmation of match between patient and blood product remains a manual process in most operating rooms (ORs), and documentation of dual-signature verification remains paper based in most medical institutions. A sentinel event at Johns Hopkins Hospital in which a seriously ill patient undergoing an emergent surgical procedure was transfused with a unit of incompatible red blood cells that had been intended for another patient in an adjacent OR led the hospital to conduct a quality improvement project to improve the safety of intraoperative blood component transfusions. METHODS: A multidisciplinary quality improvement project team led a four-phase implementation of bedside bar code transfusion verification (BBTV) for intraoperative blood product administration. Manual random sample audits of blood component transfusions were used to examine accuracy of documentation from July 2014 through June 2016. After the transition to the Epic anesthesia information management system (AIMS) in July 2016, automated Epic reports were generated to provide population-level audits. RESULTS: After initiation of BBTV and the addition of Epic AIMS, compliance with obtaining three metrics on documentation of patient identification (two electronic signatures, start and stop times of transfusion, and blood volume transfused) was improved during a one-year period to > 96%. Pre-Epic audits had shown a mean compliance of only 86%, mainly reflecting a lack of paper blood component requisitions. CONCLUSION: By implementing BBTV and using a novel intraoperative documentation process within the Epic AIMS, a safer process of blood transfusion in the ORs was initiated and documentation improved.

A Model for the Departmental Quality Management Infrastructure Within an Academic Health System.

As quality improvement and patient safety come to play a larger role in health care, academic medical centers and health systems are poised to take a leadership role in addressing these issues. Academic medical centers can leverage their large integrated footprint and have the ability to innovate in this field. However, a robust quality management infrastructure is needed to support these efforts. In this context, quality and safety are often described at the executive level and at the unit level. Yet, the role of individual departments, which are often the dominant functional unit within a hospital, in realizing health system quality and safety goals has not been addressed. Developing a departmental quality management infrastructure is challenging because departments are diverse in composition, size, resources, and needs.In this article, the authors describe the model of departmental quality management infrastructure that has been implemented at the Johns Hopkins Hospital. This model leverages the fractal approach, linking departments horizontally to support peer and organizational learning and connecting departments vertically to support accountability to the hospital, health system, and board of trustees. This model also provides both structure and flexibility to meet individual departmental needs, recognizing that independence and interdependence are needed for large academic medical centers. The authors describe the structure, function, and support system for this model as well as the practical and essential steps for its implementation. They also provide examples of its early success.

Prediction of obstructive sleep apnea using visual photographic analysis.

STUDY OBJECTIVES: Obstructive sleep apnea (OSA) has been historically underdiagnosed and may be associated with grave perioperative complications. The ASA and American Academy of Sleep Medicine recommend OSA screening prior to surgery; however, only a minority of patients are screened. The objective of this study was to determine the proficiency of anesthesiologists, otolaryngologists, and internists at predicting the presence of OSA by visual photographic analysis without the use of a computer program to assist, and determine if prediction accuracy varies by provider type. DESIGN: Prospective case series SETTING: Tertiary care hospital-based academic center PATIENTS: Fifty-six consecutive patients presenting to the sleep laboratory undergoing polysomnography had frontal and lateral photographs of the face and torso taken. INTERVENTIONS: Not applicable. MEASUREMENTS: Polysomnography outcomes and physician ratings. An obstructive apnea hypopnea index (oAHI) ≥15 was considered "positive." Twenty anesthesiologists, 10 otolaryngologists, and 11 internists viewed patient photographs and scored them as OSA "positive" or "negative" before and after being informed of patient comorbidities. MAIN RESULTS: Nineteen patients had an oAHI <15, 18 were ≥15 but <30, and 19 were ≥30. The mean oAHI was 28.7 ± 26.7 events/h (range, 0-125.7), and the mean body mass index was 34.1 ± 9.7 kg/m(2) (range, 17.4-63.7). Overall, providers predicted the correct answer with 61.8% accuracy without knowledge of comorbidities and 62.6% with knowledge (P < .0001). There was no difference between provider groups (P = .307). Prediction accuracy was unrelated to patient age (P = .067), gender (P = .306), or race (P = .087), but was related to body mass index (P = .0002). CONCLUSION: The ability to predict OSA based on visual inspection of frontal and lateral photographs is marginally superior to chance and did not differ by provider type. Knowledge of comorbidities did not improve prediction accuracy.

Obstructive sleep apnea, sleep disorders, and perioperative considerations.

Data suggest that surgical patients with obstructive sleep apnea (OSA) may be difficult to ventilate and intubate, and may be prone to postoperative complications. This article addresses the identification of patients at risk for OSA, epidemiology of the disorder, and treatment options, as well as the perioperative management of this population.

Perioperative Assessment and Management for Sleep Apnea in the Ambulatory Surgical Patient.

The overwhelming majority of surgical procedures performed in the United States are done on an outpatient basis. Patients with complicated medical problems are routinely scheduled for ambulatory procedures that have become progressively more complex. Appropriate patient selection is paramount to ensuring optimal perioperative outcomes, and the patient with known or suspected OSA presents unique challenges to the anesthesia care team regarding airway management, pain control, and postoperative monitoring requirements. Currently, a relative paucity of high-quality evidence exists on which to base guidelines or recommendations for the anesthetic care of these patients. It is generally agreed that early identification of those at risk for OSA allows for planning and implementation of strategies to help to reduce the risk of adverse perioperative events. Although various national societies have published consensus statements aimed at guiding the perioperative management of the patient at risk for OSA, more studies are needed to define the optimal approach to the perioperative care of this population.

Prevalence of Undetected Sleep Apnea in Patients Undergoing Cardiovascular Surgery and Impact on Postoperative Outcomes.

STUDY OBJECTIVE: We examined the prevalence of obstructive sleep apnea (OSA) among patients undergoing cardiac surgery and its impact on postoperative outcomes. METHODS: Subjects were recruited from inpatient cardiovascular surgery units at two tertiary care centers. Crystal Monitor 20-H recorded polysomnograms preoperatively. Regression analyses were performed to explore associations between OSA using different apnea-hypopnea index (AHI) cutoffs and postoperative outcomes adjusting for key covariates. Prevalence of postoperative outcomes was compared among groups defined by AHI and left ventricle ejection fraction (LVEF) median cutoffs. RESULTS: Of 107 participants, the AHI was ≥ 5 in 79 (73.8%), ≥ 10 in 63 (58.9%), ≥ 15 in 51(47.7%), and ≥ 30 in 29 (27.1%). Patients with AHI ≥ 15 had significantly lower LVEF (p < 0.001). Logistic regression analyses with OSA cutoffs as above adjusting for age, gender, race, BMI, and LVEF found no significant increase in odds for any postoperative outcomes. No significant differences were found in %Total sleep time (TST) with SpO2 < 90% between AHI or LVEF groups, or by presence/absence of complications. Patients with any amount of TST with SpO2 < 90% had greater BMI, longer OR tube time, and greater prevalence of prolonged intubation (p = 0.007, 0.035, 0.038, respectively). CONCLUSIONS: OSA is highly prevalent in patients undergoing cardiovascular surgery. It could not be shown that OSA was significantly associated with adverse postoperative outcomes, but this may have been due to an insufficient number of subjects. AHI ≥ 15 was associated with lower LVEF. Larger samples are required to explore the impact of OSA on key postoperative outcomes that have clinical and economic importance in the care of cardiovascular surgery populations.

Screening for Pediatric Obstructive Sleep Apnea before Ambulatory Surgery.

PURPOSE: The American Society of Anesthesia practice guidelines recommend that pediatric and adult patients who undergo ambulatory surgery be screened for obstructive sleep apnea (OSA). With this in mind, our objective was to assess the frequency of screening by anesthesia providers for the signs and symptoms of OSA in children undergoing surgery in an ambulatory setting. METHODS: Prospective single-blinded observational study of anesthesia providers' preoperative interview of caregivers of consecutive patients younger than age 18 who were scheduled for ambulatory surgery. RESULTS: One hundred one children (30 females) were identified, with a mean age of 6.9 ± 5.0 years; 54 were classified as white, 33 as black, and 14 as other. Total OSA-18 scores ranged from 18 to 97, with a mean of 33.1 ± 14.8. The mean score for adenotonsillectomy patients was higher than that for children who underwent procedures other than adenotonsillectomy. Thirty-one percent of children were screened for OSA, and snoring was the most common symptom recorded (28%). Patients who were screened for OSA were more likely to have snoring (p < 0.001), known OSA (p = 0.006), and a scheduled adenotonsillectomy (p = 0.02). CONCLUSION: OSA was not routinely screened for by anesthesia providers prior to ambulatory pediatric surgery. When screening did occur, "snoring" was the most commonly recorded symptom. Paradoxically, patients with undiagnosed OSA who would benefit the most from screening were the least likely to be screened. COMMENTARY: A commentary on this article appears in this issue on page 697.

Pediatric obstructive sleep apnea.

Obstructive sleep apnea syndrome (OSAS) is a disorder of airway obstruction with multisystem implications and associated complications. OSAS affects children from infancy to adulthood and is responsible for behavioral, cognitive, and growth impairment as well as cardiovascular and perioperative respiratory morbidity and mortality. OSAS is associated commonly with comorbid conditions, including obesity and asthma. Adenotonsillectomy is the most commonly used treatment option for OSAS in childhood, but efforts are underway to identify medical treatment options.

Risk assessment of obstructive sleep apnea in a population of patients undergoing ambulatory surgery.

STUDY OBJECTIVES: The aims of this study were to: (a) assess the prevalence of diagnosed OSA and symptoms of undiagnosed OSA in a cohort of ambulatory surgical patients, and (b) characterize the frequency of postoperative complications in outpatients with a diagnosis of or a propensity to OSA. METHODS: Patients presenting for ambulatory surgery completed a self-administered questionnaire. Using a previously validated prediction model, the probability for OSA was determined. Patients with > or = 70% propensities were considered to be at high risk of having the disorder. Relevant perioperative data and complications were tracked and recorded, and differences in median estimated propensities for OSA were considered by these data. RESULTS: Three-thousand five hundred fifty-three patients 'completed the preoperative survey. A total of 2139 patients had perioperative data and estimated propensity scores. Ninety-four of the 2139 (4.4%) patients gave a self-reported prior diagnosis of OSA. One hundred three (4.8%) patients were found to be at high risk of OSA based on the survey and prediction model. Seventy-five percent of the patients with > 70% propensity for OSA had not yet been diagnosed. There was no association between OSA propensity scores and unplanned hospital admission, however there was an association of increased propensity with difficult intubation, intraoperative use of pressors, and postoperative oxygen saturation in the PACU. CONCLUSION: The results of this study suggest that undiagnosed OSA may be relatively common in an ambulatory surgical population. There was no relationship between unplanned hospital admission and diagnosis of or increased risk of OSA. However, there was an association of increased perioperative events requiring additional anesthetic management in patients with a diagnosis of, or with a higher propensity to OSA.

The impact of obesity on outcomes after critical illness: a meta-analysis.

PURPOSE: To assess whether obesity is associated with mortality or other adverse intensive care unit (ICU) and post-ICU outcomes. METHODS: A meta-analysis of studies from PubMed and EMBASE databases. RESULTS: Twenty-two studies (n = 88,051 patients) were included. Pooled analysis demonstrated no difference in ICU mortality, but lower hospital mortality for obese and morbidly obese subjects (RR 0.76; 95% CI 0.59, 0.92; RR 0.83; 95% CI 0.66, 1.04, respectively) versus normal weight subjects. There was no association between obesity and duration of mechanical ventilation or ICU stay. Morbidly obese versus normal weight patients had longer hospitalizations. No study reported physical function, mental health, or quality of life outcomes after discharge. CONCLUSIONS: Obesity is not associated with increased risk for ICU mortality, but may be associated with lower hospital mortality. There is a critical lack of research on how obesity may affect complications of critical illness and patient long-term outcomes.

Preclinical and clinical evaluation of sulforaphane for chemoprevention in the breast.

Consumers of higher levels of Brassica vegetables, particularly those of the genus Brassica (broccoli, Brussels sprouts and cabbage), reduce their susceptibility to cancer at a variety of organ sites. Brassica vegetables contain high concentrations of glucosinolates that can be hydrolyzed by the plant enzyme, myrosinase, or intestinal microflora to isothiocyanates, potent inducers of cytoprotective enzymes and inhibitors of carcinogenesis. Oral administration of either the isothiocyanate, sulforaphane, or its glucosinolate precursor, glucoraphanin, inhibits mammary carcinogenesis in rats treated with 7,12-dimethylbenz[a]anthracene. In this study, we sought to determine whether sulforaphane exerts a direct chemopreventive action on animal and human mammary tissue. The pharmacokinetics and pharmacodynamics of a single 150 mumol oral dose of sulforaphane were evaluated in the rat mammary gland. We detected sulforaphane metabolites at concentrations known to alter gene expression in cell culture. Elevated cytoprotective NAD(P)H:quinone oxidoreductase (NQO1) and heme oxygenase-1 (HO-1) gene transcripts were measured using quantitative real-time polymerase chain reaction. An observed 3-fold increase in NQO1 enzymatic activity, as well as 4-fold elevated immunostaining of HO-1 in rat mammary epithelium, provides strong evidence of a pronounced pharmacodynamic action of sulforaphane. In a subsequent pilot study, eight healthy women undergoing reduction mammoplasty were given a single dose of a broccoli sprout preparation containing 200 mumol of sulforaphane. Following oral dosing, sulforaphane metabolites were readily measurable in human breast tissue enriched for epithelial cells. These findings provide a strong rationale for evaluating the protective effects of a broccoli sprout preparation in clinical trials of women at risk for breast cancer.

Demographics and diagnosis of obstructive sleep apnea.

This article reviews the terminology of obstructive sleep apnea and the associated diagnostic tests and provides an overview of the risk factors for this chronic condition. Sleep apnea affects 2% to 4% of middle-aged working adults in the general population, however, a considerable number of affected individuals remain undiagnosed. Patients with the disease may be at a higher risk for adverse perioperative outcomes. Knowledge of factors associated with an increased risk of obstructive sleep apnea is vital to the perioperative assessment and anesthetic plan.
