Prescription of guideline-directed medical therapies in patients with diabetes and chronic kidney disease from the CURE-CKD Registry, 2019-2020.

AIM: Guideline-directed medical therapy (GDMT) is designed to improve clinical outcomes. The study aim was to assess GDMT prescribing rates and prescribing-persistence predictors in patients with diabetes and chronic kidney disease (CKD) from the Center for Kidney Disease Research, Education, and Hope Registry. MATERIALS AND METHODS: Data were obtained from adults ≥18 years old with diabetes and CKD between 1 January 2019 and 31 December 2020 (N = 39 158). Baseline and persistent (≥90 days) prescriptions for GDMT, including angiotensin converting enzyme (ACE) inhibitor/angiotensin receptor blocker (ARB), sodium-glucose cotransporter-2 (SGLT2) inhibitor and glucagon-like peptide 1 (GLP-1) receptor agonist were assessed. RESULTS: The population age (mean ± SD) was 70 ± 14 years, and 49.6% (n = 19 415) were women. Baseline estimated glomerular filtration rate (2021 CKD-Epidemiology Collaboration creatinine equation) was 57.5 ± 23.0 ml/min/1.73 m2 and urine albumin/creatinine 57.5 mg/g (31.7-158.2; median, interquartile range). Baseline and ≥90-day persistent prescribing rates, respectively, were 70.7% and 40.4% for ACE inhibitor/ARB, 6.0% and 5.0% for SGLT2 inhibitors, and 6.8% and 6.3% for GLP-1 receptor agonist (all p < .001). Patients lacking primary commercial health insurance coverage were less likely to be prescribed an ACE inhibitor/ARB [odds ratio (OR) = 0.89; 95% confidence interval (CI) 0.84-0.95; p < .001], SGLT2 inhibitor (OR 0.72; 95% CI 0.64-0.81; p < .001) or GLP-1 receptor agonist (OR 0.89; 95% CI 0.80-0.98; p = .02). GDMT prescribing rates were lower at Providence than UCLA Health. CONCLUSIONS: Prescribing for GDMT was suboptimal and waned quickly in patients with diabetes and CKD. Type of primary health insurance coverage and health system were associated with GDMT prescribing.

Intraoperative Hypotension and Acute Kidney Injury in Non-cardiac Surgery at a Large Tertiary Care Medical Center.

Acute kidney injury (AKI) is a serious postoperative complication that increases patients' risk for long- and shortterm morbidity and mortality. Risk for developing AKI increases following intraoperative hypotension (IOH). This project aimed to describe the rate of and establish IOH as an independent risk factor for AKI among adults undergoing non-cardiac surgery at a large tertiary care medical center. An observational, retrospective, evidence-based practice project was conducted. Records were extracted for adults undergoing general anesthesia for non-cardiac surgery from 2015 to 2019 with available serum creatinine laboratory results. The primary project outcome was postoperative AKI. Among 4,603 cases, 8.9% experienced postoperative AKI. Cases with IOH (MAPs less than 60 mmHg for at least 10 minutes) compared to cases without IOH had increased risks for AKI (RR 1.48, 95% CI [1.19-1.84], P<.001). In a fully adjusted model, IOH was an independent risk factor for AKI (OR 1.50, 95% CI [1.18-1.92], P=.001). Among cases with serum creatinine laboratory results, the rate of AKI was higher than reported literature rates. IOH was confirmed as an independent risk factor. Quantifying the rate of and risk factors for AKI may precipitate heightened attention to prevention strategies and encourage quality improvement initiatives.

Patient Activation, Depressive Symptoms, and Self-Rated Health: Care Management Intervention Effects among High-Need, Medically Complex Adults.

The purpose of this randomized controlled trial (n = 268) at a Federally Qualified Health Center was to evaluate the outcomes of a care management intervention versus an attention control telephone intervention on changes in patient activation, depressive symptoms and self-rated health among a population of high-need, medically complex adults. Both groups had similar, statistically significant improvements in patient activation and self-rated health. Both groups had significant reductions in depressive symptoms over time; however, the group who received the care management intervention had greater reductions in depressive symptoms. Participants in both study groups who had more depressive symptoms had lower activation at baseline and throughout the 12 month study. Findings suggest that patients in the high-need, medically complex population can realize improvements in patient activation, depressive symptoms, and health status perceptions even with a brief telephone intervention. The importance of treating depressive symptoms in patients with complex health conditions is highlighted.

Evidence-Based Project: Cost Savings and Reduction in Environmental Release With Low-Flow Anesthesia.

Volatile anesthetic agents act as greenhouse gases. Low-flow anesthesia techniques (≤1 L/min) are associated with lower costs. Decreasing volatile anesthetic delivery provides safe and effective strategies for anesthesia providers to decrease costs and reduce environmental pollution. This evidence-based project aimed to estimate cost savings and reduction in the environmental release of anesthetic gases, under simulated lower fresh gas flow (FGF) practices. For each surgical case, the exhaled anesthetic gas percent and FGF data were used to calculate the volume of fluid volatile anesthetic. The fluid volatile anesthetic for each case was then estimated using simulated FGFs. Changes in volatile agent cost and environmental release of anesthetic gases were predicted. Sevoflurane was the most commonly used volatile agent. The mean FGF for cases using sevoflurane was 2.5 L/min. The simulated FGF of 1 L/min FGF across all agents predicted a 48% ($50,892) reduction in costs of volatile anesthetics and a 42% (33 metric tons of carbon dioxide equivalent) decrease in carbon emissions. Simulated low-flow anesthesia demonstrated cost savings and environmental conservation. Project findings align with current literature showing that lowering FGFs represents an area of cost containment and an opportunity to lessen the environmental impact of anesthesia.

Reducing Surgery Scheduling Errors in Multihospital System.

OBJECTIVE: The purpose of this study was to assess whether bundled team training interventions for surgeons and office staff could effectively improve the accuracy of surgery scheduling, minimizing scheduling factors that may contribute to occurrence of wrong site surgery. METHODS: This quasi-experimental observational study used an interrupted time series design to explore surgery scheduling errors (SSEs) and implemented bundled team training interventions intended to reduce SSEs at a Pacific Northwest Regional Surgery Scheduling Department. Each preintervention and postintervention segment consisted of 16 weekly data points. The bundled team training interventions included disclosure of preintervention scheduling errors, a scheduling verification checklist, an updated surgery scheduling policy and procedure, and toolkit to improve office scheduling of surgeries. RESULTS: Improvements in SSEs were observed preintervention to postintervention, with decreased surgery SSE rate from 0.51% to 0.13% (P < 0.001). Reductions were observed in all SSE types. The segmented linear trend demonstrated an observed reduction of 42.70 SSE (P < 0.001). CONCLUSIONS: This is the first study conducted at a large healthcare system with a regional surgery scheduling department to demonstrate that statistically significant and clinically important reductions in SSEs can be achieved. The findings demonstrate that SSEs can be minimized and confirm that verification processes must begin in the surgeon's office once a decision has been reached to proceed with surgery. The study confirms the need for additional research targeted at understanding why SSEs occur at the time of scheduling.

Medication use, renin-angiotensin system inhibitors, and acute care utilization after hospitalization in patients with chronic kidney disease.

OBJECTIVES: The aims of this secondary analysis were to: (a) characterize medication use following hospital discharge for patients with chronic kidney disease (CKD), and (b) investigate relationships of medication use with the primary composite outcome of acute care utilization 90 days after hospitalization. METHODS: The CKD-Medication Intervention Trial (CKD-MIT) enrolled acutely ill hospitalized patients with CKD stages 3-5 not dialyzed (CKD 3-5 ND). In this post hoc analysis, data for medication use were characterized, and the relationship of medication use with the primary outcome was evaluated using Cox proportional hazards models. RESULTS: Participants were taking a mean of 12.6 (standard deviation=5.1) medications, including medications from a wide variety of medication classes. Nearly half of study participants were taking angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers (ARB). ACE inhibitor/ARB use was associated with decreased risk of the primary outcome (hazard ratio=0.51; 95% confidence interval 0.28-0.95; p=0.03) after adjustment for baseline estimated glomerular filtration rate, age, sex, race, blood pressure, albuminuria, and potential nephrotoxin use. CONCLUSIONS: A large number, variety, and complexity of medications were used by hospitalized patients with CKD 3-5 ND. ACE inhibitor or ARB use at hospital discharge was associated with a decreased risk of 90-day acute care utilization.

Conversion of Urine Protein-Creatinine Ratio or Urine Dipstick Protein to Urine Albumin-Creatinine Ratio for Use in Chronic Kidney Disease Screening and Prognosis : An Individual Participant-Based Meta-analysis.

BACKGROUND: Although measuring albuminuria is the preferred method for defining and staging chronic kidney disease (CKD), total urine protein or dipstick protein is often measured instead. OBJECTIVE: To develop equations for converting urine protein-creatinine ratio (PCR) and dipstick protein to urine albumin-creatinine ratio (ACR) and to test their diagnostic accuracy in CKD screening and staging. DESIGN: Individual participant-based meta-analysis. SETTING: 12 research and 21 clinical cohorts. PARTICIPANTS: 919 383 adults with same-day measures of ACR and PCR or dipstick protein. MEASUREMENTS: Equations to convert urine PCR and dipstick protein to ACR were developed and tested for purposes of CKD screening (ACR ≥30 mg/g) and staging (stage A2: ACR of 30 to 299 mg/g; stage A3: ACR ≥300 mg/g). RESULTS: Median ACR was 14 mg/g (25th to 75th percentile of cohorts, 5 to 25 mg/g). The association between PCR and ACR was inconsistent for PCR values less than 50 mg/g. For higher PCR values, the PCR conversion equations demonstrated moderate sensitivity (91%, 75%, and 87%) and specificity (87%, 89%, and 98%) for screening (ACR >30 mg/g) and classification into stages A2 and A3, respectively. Urine dipstick categories of trace or greater, trace to +, and ++ for screening for ACR values greater than 30 mg/g and classification into stages A2 and A3, respectively, had moderate sensitivity (62%, 36%, and 78%) and high specificity (88%, 88%, and 98%). For individual risk prediction, the estimated 2-year 4-variable kidney failure risk equation using predicted ACR from PCR had discrimination similar to that of using observed ACR. LIMITATION: Diverse methods of ACR and PCR quantification were used; measurements were not always performed in the same urine sample. CONCLUSION: Urine ACR is the preferred measure of albuminuria; however, if ACR is not available, predicted ACR from PCR or urine dipstick protein may help in CKD screening, staging, and prognosis.

Clinical Characteristics of and Risk Factors for Chronic Kidney Disease Among Adults and Children: An Analysis of the CURE-CKD Registry.

Importance: Chronic kidney disease (CKD) is serious and common, yet recognition and public health responses are limited. Objective: To describe clinical features of, prevalence of, major risk factors for, and care for CKD among patients treated in 2 large US health care systems. Design, Setting, and Participants: This cohort study collected data from the Center for Kidney Disease Research, Education, and Hope (CURE-CKD) registry, an electronic health record-based registry jointly curated and sponsored by Providence St Joseph Health and the University of California, Los Angeles. Patients were adults and children with CKD (excluding end-stage kidney disease) and adults at risk of CKD (ie, with diabetes, hypertension, or prediabetes) identified by laboratory values, vital signs, prescriptions, and administrative codes. Data were collected from January 2006 through December 2017, with analyses performed from March 2019 through November 2019. Exposures: Diabetes, hypertension, and prediabetes. Main Outcomes and Measures: Clinical and demographic characteristics, prevalence, and prescribed medications. Results: Of 2 625 963 adults and children in the sample, 606 064 adults (23.1%) with CKD had a median (interquartile range [IQR]) age of 70 (59-81) years, with 338 785 women (55.9%) and 434 474 non-Latino white individuals (71.7%). A total of 12 591 children (0.4%) with CKD had a median (IQR) age of 6 (1-13) years, with 7079 girls (56.2%) and 6653 non-Latino white children (52.8%). Median (IQR) estimated glomerular filtration rate was 53 (41-61) mL/min/1.73 m2 among adults and 70 (50-95) mL/min/1.73 m2 in children. Prevalence rates for CKD in adults were 4.8% overall (606 064 of 12 669 700) with 1.6% (93 644 of 6 011 129) during 2006 to 2009, 5.7% (393 455 of 6 903 084) during 2010 to 2013, and 8.4% (683 574 of 8 179 860) during 2014 to 2017 (P < .001). A total of 226 693 patients (37.4%) had category 3a CKD; 100 239 (16.5%), category 3b CKD; 39 125 (6.5%), category 4 CKD; and 20 328 (3.4%), category 5 CKD. Among adults with CKD, albuminuria and proteinuria assessments were available in 52 551 (8.7%) and 25 035 (4.1%) patients, respectively. A renin-angiotensin system inhibitor was prescribed to 124 575 patients (20.6%), and 204 307 (33.7%) received nonsteroidal anti-inflammatory drugs or proton pump inhibitors. Of 1 973 258 adults (75.1%) at risk, one-quarter had diabetes or prediabetes (512 299 [26.0%]), nearly half had hypertension (955 812 [48.4%]), and one-quarter had both hypertension and diabetes or prediabetes (505 147 [25.6%]). Conclusions and Relevance: This registry-based cohort study revealed a burgeoning number of patients with CKD and its major risk factors. Rates of identification and use of kidney protective agents were low, while potential nephrotoxin use was widespread, underscoring the pressing need for practice-based improvements in CKD prevention, recognition, and treatment.

Rationale and design of a multicenter Chronic Kidney Disease (CKD) and at-risk for CKD electronic health records-based registry: CURE-CKD.

BACKGROUND: Chronic kidney disease (CKD) is a global public health problem, exhibiting sharp increases in incidence, prevalence, and attributable morbidity and mortality. There is a critical need to better understand the demographics, clinical characteristics, and key risk factors for CKD; and to develop platforms for testing novel interventions to improve modifiable risk factors, particularly for the CKD patients with a rapid decline in kidney function. METHODS: We describe a novel collaboration between two large healthcare systems (Providence St. Joseph Health and University of California, Los Angeles Health) supported by leadership from both institutions, which was created to develop harmonized cohorts of patients with CKD or those at increased risk for CKD (hypertension/HTN, diabetes/DM, pre-diabetes) from electronic health record data. RESULTS: The combined repository of candidate records included more than 3.3 million patients with at least a single qualifying measure for CKD and/or at-risk for CKD. The CURE-CKD registry includes over 2.6 million patients with and/or at-risk for CKD identified by stricter guide-line based criteria using a combination of administrative encounter codes, physical examinations, laboratory values and medication use. Notably, data based on race/ethnicity and geography in part, will enable robust analyses to study traditionally disadvantaged or marginalized patients not typically included in clinical trials. DISCUSSION: CURE-CKD project is a unique multidisciplinary collaboration between nephrologists, endocrinologists, primary care physicians with health services research skills, health economists, and those with expertise in statistics, bio-informatics and machine learning. The CURE-CKD registry uses curated observations from real-world settings across two large healthcare systems and has great potential to provide important contributions for healthcare and for improving clinical outcomes in patients with and at-risk for CKD.

Association of Acute Kidney Injury with Cardiovascular Events and Death in Systolic Blood Pressure Intervention Trial.

RATIONALE AND OBJECTIVE: In the Systolic Blood Pressure Intervention Trial, the possible relationships between acute kidney injury (AKI) and risk of major cardiovascular events and death are not known. STUDY DESIGN: Post hoc analysis of a multicenter, randomized, controlled, open-label clinical trial. SETTING AND PARTICIPANTS: Hypertensive adults without diabetes who were ≥50 years of age with prior cardiovascular disease, chronic kidney disease (CKD), 10-year Framingham risk score > 15%, or age > 75 years were assigned to a systolic blood pressure target of < 120 mm Hg (intensive) or < 140 mm Hg (standard). PREDICTOR: AKI episodes. OUTCOMES: The primary outcome was a composite of myocardial infarction, acute coronary syndrome, stroke, decompensated heart failure, or cardiovascular death. The secondary outcome was death from any cause. Analytical Approach: AKI was defined using the Kidney Disease: Improving Global Outcomes modified criteria based solely upon serum creatinine. AKI episodes were identified by serious adverse events or emergency room visits. Cox proportional hazards models assessed the risk for the primary and secondary outcomes by AKI status. RESULTS: Participants were 68 ± 9 years of age, 36% women (3,332/9,361), and 30% Black race (2,802/9,361), and 17% (1,562/9,361) with cardiovascular disease. Systolic blood pressure was 140 ± 16 mm Hg at study entry. AKI occurred in 4.4% (204/4,678) and 2.6% (120/4,683) in the intensive and standard treatment groups respectively (p < 0.001). Those who experienced AKI had higher risk of cardiovascular events (hazard ratio [HR] 1.52, 95% CI 1.05-2.20, p = 0.026) and death from any cause (HR 2.33, 95% CI 1.56-3.48, p < 0.001) controlling for age, sex, race, baseline systolic blood pressure, body mass index, number of antihypertensive medications, cardiovascular disease and CKD status, hypotensive episodes, and treatment assignment. LIMITATIONS: The study was not prospectively designed to determine relationships between AKI, cardiovascular events, and death. CONCLUSIONS: Among older adults with hypertension at high cardiovascular risk, intensive treatment of blood pressure independently increased risk of AKI, which substantially raised risks of major cardiovascular events and death.

Hospice Use And End-Of-Life Spending Trajectories In Medicare Beneficiaries On Hemodialysis.

Infrequent and late referral to hospice among patients on dialysis likely reflects the impact of a Medicare payment policy that discourages the concurrent receipt of these services, but it may also reflect these patients' less predictable illness trajectories. Among a national cohort of patients on hemodialysis, we identified four distinct spending trajectories during the last year of life that represented markedly different intensities of care. Within the cohort, 9 percent had escalating spending and 13 percent had persistently high spending throughout the last year of life, while 41 percent had relatively low spending with late escalation, and 37 percent had moderate spending with late escalation. Across the four groups, the percentages of patients enrolled in hospice at the time of death were uniformly low ranging from only 19 percent of those with persistently high costs to 21 percent of those with moderate costs and the median number of days spent in hospice during the last year of life was virtually the same (either five or six days). These findings signal the need for greater flexibility in the provision of end-of-life care in this population.

Impact of Adoption of a Comprehensive Electronic Health Record on Nursing Work and Caring Efficacy.

Nurses in acute care settings are affected by the technologies they use, including electronic health records. This study investigated the impacts of adoption of a comprehensive electronic health record by measuring nursing locations and interventions in three units before and 12 months after adoption. Time-motion methodology with a handheld recording platform based on Omaha System standardized terminology was used to collect location and intervention data. In addition, investigators administered the Caring Efficacy Scale to better understand the effects of the electronic health record on nursing care efficacy. Several differences were noted after the electronic health record was adopted. Nurses spent significantly more time in patient rooms and less in other measured locations. They spent more time overall performing nursing interventions, with increased time in documentation and medication administration, but less time reporting and providing patient-family teaching. Both before and after electronic health record adoption, nurses spent most of their time in case management interventions (coordinating, planning, and communicating). Nurses showed a slight decrease in perceived caring efficacy after adoption. While initial findings demonstrated a trend toward increased time efficiency, questions remain regarding nurse satisfaction, patient satisfaction, quality and safety outcomes, and cost.

In-Hospital Sepsis Mortality Rates Comparing Tertiary and Non-Tertiary Hospitals in Washington State.

BACKGROUND: More than a million people a year in the United States experience sepsis or sepsis-related complications, and sepsis remains the leading cause of in-hospital deaths. Unlike many other leading causes of in-hospital mortality, sepsis detection and treatment are not dependent on the presence of any technology or services that differ between tertiary and non-tertiary hospitals. OBJECTIVE: To compare sepsis mortality rates between tertiary and non-tertiary hospitals in Washington State. METHODS: A retrospective longitudinal, observational cohort study of 73 Washington State hospitals for 2010-2015 using data from a standardized state database of hospital abstracts. Abstract records on adult patients (n = 86,378) admitted through the emergency department (ED) from 2010 through 2015 in all tertiary (n = 7) and non-tertiary (n = 66) hospitals in Washington State. RESULTS: The overall mortality rate for all hospitals was 6.5%. In the fully adjusted model, the odds ratio for in-hospital death was higher in non-tertiary hospitals compared with tertiary hospitals (odds ratio 1.25; 95% confidence interval 1.17-1.35; p < 0.001). CONCLUSIONS: We observed higher sepsis mortality rates in non-tertiary hospitals, compared with tertiary hospitals. Because most patients who are treated for sepsis are treated outside of tertiary hospitals, and the number of patients treated for sepsis in non-tertiary hospitals seems to be rising, a better understanding of the cause or causes for this differential is crucial.

The Reliability of Electronic Health Record Data Used for Obstetrical Research.

BACKGROUND: Hospital electronic health record (EHR) data are increasingly being called upon for research purposes, yet only recently has it been tested to examine its reliability. Studies that have examined reliability of EHR data for research purposes have varied widely in methods used and field of inquiry, with little reporting of the reliability of perinatal and obstetric variables in the current literature. OBJECTIVE: To assess the reliability of data extracted from a commercially available inpatient EHR as compared with manually abstracted data for common attributes used in obstetrical research. METHODS: Data extracted through automated EHR reports for 3,250 women who delivered a live infant at a large hospital in the Pacific Northwest were compared with manual chart abstraction for the following perinatal measures: delivery method, labor induction, labor augmentation, cervical ripening, vertex presentation, and postpartum hemorrhage. RESULTS: Almost perfect agreement was observed for all four modes of delivery (vacuum assisted: kappa = 0.92; 95% confidence interval [CI] = 0.88-0.95, forceps assisted: kappa = 0.90; 95%CI = 0.76-1.00, cesarean delivery: kappa = 0.91; 95%CI = 0.90-0.93, and spontaneous vaginal delivery: kappa = 0.91; 95%CI = 0.90-0.93). Cervical ripening demonstrated substantial agreement (kappa = 0.77; 95%CI = 0.73-0.80); labor induction (kappa = 0.65; 95%CI = 0.62-0.68) and augmentation (kappa = 0.54; 95%CI = 0.49-0.58) demonstrated moderate agreement between the two data sources. Vertex presentation (kappa = 0.35; 95%CI = 0.31-0.40) and post-partum hemorrhage (kappa = 0.21; 95%CI = 0.13-0.28) demonstrated fair agreement. CONCLUSION: Our study demonstrates variability in the reliability of obstetrical data collected and reported through the EHR. While delivery method was satisfactorily reliable in our sample, other examined perinatal measures were less so when compared with manual chart abstraction. The use of multiple modalities for assessing reliability presents a more consistent and rigorous approach for assessing reliability of data from EHR systems and underscores the importance of requiring validation of automated EHR data for research purposes.

Medication Therapy Management after Hospitalization in CKD: A Randomized Clinical Trial.

BACKGROUND AND OBJECTIVES: CKD is characterized by remarkably high hospitalization and readmission rates. Our study aim was to test a medication therapy management intervention to reduce subsequent acute care utilization. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: The CKD Medication Intervention Trial was a single-blind (investigators), randomized clinical trial conducted at Providence Health Care in Spokane, Washington. Patients with CKD stages 3-5 not treated by dialysis who were hospitalized for acute illness were recruited. The intervention was designed to improve posthospitalization care by medication therapy management. A pharmacist delivered the intervention as a single home visit within 7 days of discharge. The intervention included these fundamental elements: comprehensive medication review, medication action plan, and a personal medication list. The primary outcome was a composite of acute care utilization (hospital readmissions and emergency department and urgent care visits) for 90 days after hospitalization. RESULTS: Baseline characteristics of participants (n=141) included the following: age, 69±11 (mean±SD) years old; women, 48% (67 of 141); diabetes, 56% (79 of 141); hypertension, 83% (117 of 141); eGFR, 41±14 ml/min per 1.73 m2 (serum creatinine-based Chronic Kidney Disease Epidemiology Collaboration equation); and urine albumin-to-creatinine ratio median, 43 mg/g (interquartile range, 8-528) creatinine. The most common primary diagnoses for hospitalization were the following: cardiovascular events, 36% (51 of 141); infections, 18% (26 of 141); and kidney diseases, 12% (17 of 141). The primary outcome occurred in 32 of 72 (44%) of the medication intervention group and 28 of 69 (41%) of those in usual care (log rank P=0.72). For only hospital readmission, the rate was 19 of 72 (26%) in the medication intervention group and 18 of 69 (26%) in the usual care group (log rank P=0.95). There was no between-group difference in achievement of guideline-based goals for use of renin-angiotensin system inhibition or for BP, hemoglobin, phosphorus, or parathyroid hormone. CONCLUSIONS: Acute care utilization after hospitalization was not reduced by a pharmacist-led medication therapy management intervention at the transition from hospital to home.

Time motion analysis of nursing work in ICU, telemetry and medical-surgical units.

AIM: This study examined nurses' work, comparing nursing interventions and locations across three units in a United States hospital using Omaha System standardized terminology as the organizing framework. BACKGROUND: The differences in nurses' acute-care work across unit types are not well understood. Prior investigators have used time-motion methodologies; few have compared differences across units, nor used standardized terminology. METHODS: Nurse-observers recorded locations and interventions of nurses on three acute-care units using hand-held devices and web-based TimeCaT™ software. Nursing interventions were mapped to Omaha System terms. Unit-differences were analysed. RESULTS: Nurses changed locations approximately every 2 min, and averaged approximately one intervention/minute. Unit differences were found in both the interventions performed and the locations. Most interventions were case-management related, demonstrating the nurses' patient management/coordination role. CONCLUSIONS: Unit differences in nursing interventions and location were found among three unit types. Omaha System terminology, as well as the observational method used, were found to be feasible and practical. IMPLICATIONS FOR NURSING MANAGEMENT: Nursing work varies by unit, yet managers have not been armed with empirical data with which to make more informed decisions about nurses' work priorities, clinical outcomes, patient satisfaction, staff satisfaction and cost. The results from this study will help them to do so.

The Cost of Nurse-Midwifery Care: Use of Interventions, Resources, and Associated Costs in the Hospital Setting.

INTRODUCTION: Obstetrical care often involves multiple expensive, and often elective, interventions that may increase costs to patients, payers, and the health care system with little effect on patient outcomes. The objectives of this study were to examine the following hospital related outcomes: 1) use of labor and birth interventions, 2) inpatient duration of stay, and 3) total direct health care costs for patients attended by a certified nurse-midwife (CNM) compared with those attended by an obstetrician-gynecologist (OB-GYN), within an environment of safe and high-quality care. MATERIAL AND METHODS: Electronic health records for 1,441 medically low-risk women who gave birth at a hospital located in the U.S. Pacific Northwest between January and September 2013 were sampled. Multilevel regression and generalized linear models were used for analysis. RESULTS: Reduced use of selected labor and birth interventions (cesarean delivery, vacuum-assisted delivery, epidural anesthesia, labor induction, and cervical ripening), reduced maternal duration of stay, and reduced overall costs associated with CNM-led care relative to OB-GYN-led care were observed for medically low-risk women in a hospital setting. Maternal and neonatal outcomes were comparable across groups. CONCLUSIONS: This study supports consideration of increased use of CNMs as providers for the care of women at low risk for complications to decrease costs for the health care system. The use of CNMs to the fullest extent within state-regulated scopes of practice could result in more efficient use of hospital resources.

Geographic Variation in Treatment and Outcomes Among Patients With AMI: Investigating Urban-Rural Differences Among Hospitalized Patients.

BACKGROUND: The value of early invasive revascularization for patients suffering acute myocardial infarction (AMI) is well known. However, access to revascularization services varies geographically and demographically. Previous studies have not examined the influence of rural residence on revascularization rates and outcomes among patients hospitalized with AMI. METHODS: Our retrospective cohort study included patients hospitalized in Washington State with a primary diagnosis of AMI from 2009 to 2012. Urban or rural residence was determined using rural-urban commuting area (RUCA) codes. Multivariable models were used to evaluate geographic variation in rates of invasive versus medical management, in-hospital mortality, rehospitalization, and subsequent revascularization procedures. RESULTS: Our study included 25,156 urban dwellers and 2,770 rural residents. Adjusted models found rural patients to be at increased odds of undergoing invasive revascularization during the initial episode of AMI care (OR = 1.11; 95% CI: 1.01-1.21; P = .02) compared to urban dwelling patients. Rural patients were more likely to be transferred for care (OR = 4.28; 95% CI: 3.93-4.66; P < .001) and more likely to undergo coronary artery bypass grafting (CABG) (OR = 1.55; 95% CI: 1.35-1.78; P < .001) compared to the urban cohort. We found no significant geographic cohort differences in in-hospital mortality or subsequent revascularization rates. CONCLUSION: Our findings suggest that despite limited access to cardiac care facilities, rural patients are accessing revascularization services. However, rural residents are more likely to undergo CABG during their index admission. High transfer rates suggest that rural regions rely on effective transfer networks to access invasive cardiac services.
