Item (506) The complex relationship between pain intensity and physical functioning in fibromyalgia: the mediating role of depression(The Journal of Pain, 2016) Steiner, Jennifer L.; Bigatti, Silvia M.; Slaven, James E.; Ang, Dennis C.Fibromyalgia (FM) is typically associated with the experience of diffuse pain and physical impairment. Depression also commonly co-exists in patients with FM, and it has been correlated with pain intensity and physical functioning. Previous research suggests an association between pain intensity and physical functioning; however, the direct causal relationship between improvements in pain intensity and in functioning is not observed in many FM patients. This may suggest that another factor such as depression is mediating this relationship. The present work examined the possibility of a mediating role of depression in the relationship between pain intensity and functioning over the course of time. 216 patients with FM completed self-report measures of pain intensity, depression, and physical impairment as part of a larger longitudinal study which investigated interventions to increase physical activity among FM patients. Assessments were completed at baseline, 12 weeks, 24 weeks, and 36 weeks. Longitudinal mediational analyses indicated that depression is a statistically significant partial mediator of the relationship between pain intensity and self-reported physical functioning at all four assessment points. To the authors’ knowledge, this is the first study to explicitly examine this relationship in a sample of FM patients, as well as the first to do so using a longitudinal design; this may significantly add to our understanding of the complexities behind creating improvements in physical functioning in this population. Clinical implication for these findings include focusing on depression and psychological correlates of depression as first line therapeutic targets in improving physical functioning of patients with FM, and treating co-morbid depression in patients with fibromyalgia earlier in the course of treatment to prevent engagement in and the perpetuation of the cycle of disability. This work was a secondary data analysis from a study funded by the National Institute of Arthritis and Musculoskeletal and Skin Diseases.Item A descriptive study of the multidisciplinary healthcare experiences of inpatient resuscitation events(Elsevier, 2023-01-06) Varner-Perez, Shelley E.; Shelley E., Kelly A. L.; Banks, Sarah K.; Burke, Emily S.; Slaven, James E.; Morse, Gregory J.; Whitaker, Myra K.; Cottingham, Ann H.; Ahmed, Rami A.; Biostatistics, School of Public HealthBackground: In-hospital resuscitation events have complex and enduring effects on clinicians, with implications for job satisfaction, performance, and burnout. Ethically ambiguous cases are associated with increased moral distress. We aim to quantitatively describe the multidisciplinary resuscitation experience. Methods: Multidisciplinary in-hospital healthcare professionals at an adult academic health center in the Midwestern United States completed surveys one and six weeks after a resuscitation event. Surveys included demographic data, task load (NASA-TLX), overall and moral distress, anxiety, depression, and spiritual peace. Spearman's rank correlation was computed to assess task load and distress. Results: During the 5-month study period, the study included 12 resuscitation events across six inpatient units. Of 82 in-hospital healthcare professionals eligible for recruitment, 44 (53.7%) completed the one-week post-resuscitation event survey. Of those, 37 (84.1%) completed the six-week survey. Highest median task load burden at one week was seen for temporal demand, effort, and mental demand. Median moral distress scores were low, while "at peace" median scores tended to be high. There were no significant non-zero changes in task load or distress scores from weeks 1-6. Mental demand (r = 0.545, p < 0.001), physical demand (r = 0.464, p = 0.005), performance (r = -0.539, p < 0.001), and frustration (r = 0.545, p < 0.001) significantly correlated with overall distress. Performance (r = -0.371, p = 0.028) and frustration (r = 0.480, p = 0.004) also significantly correlated with moral distress. Conclusions: In-hospital healthcare professionals' experiences of resuscitation events are varied and complex. Aspects of task load burden including mental and physical demand, performance, and frustration contribute to overall and moral distress, deserving greater attention in clinical contexts.Item A Scoring System for Predicting Nonunion After Intramedullary Nailing of Femoral Shaft Fractures(Wolters Kluwer, 2024-09-04) Kraus, Kent R.; Flores, Joshua W.; Slaven, James E.; Sharma, Ishani; Arnold, Payton K.; Mullis, Brian H.; Natoli, Roman M.; Orthopaedic Surgery, School of MedicineIntroduction: Femoral shaft nonunion negatively affects patient quality of life. Although multiple risk factors have been identified for femoral shaft nonunion after intramedullary nail (IMN) fixation, there is no quantitative model for predicting nonunion. Study description: The study is a retrospective cohort study of patients with femoral shaft fractures treated at two level one trauma centers who were followed to fracture union or nonunion. Patient, injury, and surgical characteristics were analyzed to create a quantitative model for nonunion risk after intramedullary nailing. Methods: Eight hundred one patients aged 18 years and older with femoral shaft fractures treated with reamed, locked IMNs were identified. Risk factors including demographics, comorbidities, surgical variables, and injury-related characteristics were evaluated. Multivariate analysis was conducted, and several variables were included in a scoring system to predict nonunion risk. Results: The overall nonunion rate was 7.62% (61/801). Multivariate analysis showed significant association among pulmonary injury (odds ratio [OR] = 2.19, P = 0.022), open fracture (OR=2.36, P = 0.02), current smoking (OR=3.05, P < 0.001), postoperative infection (OR=12.1, P = 0.007), AO/OTA fracture pattern type A or B (OR=0.43, P = 0.014), and percent cortical contact obtained intraoperatively ≥25% (OR=0.41, P = 0.021) and nonunion. The scoring system created to quantitatively stratify nonunion risk showed that a score of 3 or more yielded an OR of 6.38 for nonunion (c-statistic = 0.693, P < 0.0001). Conclusions: Femoral shaft nonunion risk is quantifiable based on several independent injury, patient, and surgical factors. This scoring system is an additional tool for clinical decision making when caring for patients with femoral shaft fractures treated with IMNs.Item Admission Factor V Predicts Transplant-Free Survival in Acute Liver Failure(Springer, 2021) Patidar, Kavish R.; Davis, Brian C.; Slaven, James E.; Ghabril, Marwan S.; Kubal, Chandrashekhar A.; Lee, William M.; Stravitz, Richard T.; Biostatistics and Health Data Science, Richard M. Fairbanks School of Public HealthBackground and aims: Traditional laboratory markers are insensitive in distinguishing between patients with acute liver failure (ALF) who will require urgent liver transplantation (LT) from those who will recover spontaneously, particularly within 24 h of presentation. Coagulation factor-V (FV) may improve the accuracy of outcome prediction in ALF due to its predominant synthesis in the liver and short half-life in plasma. Methods: Patients enrolled in the ALF Study Group Registry from a single site had FV determined within 24 h of presentation (Derivation-Cohort). Area under the receiver operating characteristic curves (AUROC) dichotomized by ALF etiology [acetaminophen (APAP) or non-APAP] were constructed to evaluate the diagnostic performance of FV for transplant-free-survival (TFS). Multivariate logistic regression modeling was performed using FV and other clinical variables to predict TFS. Accuracy of FV and multivariable model were performed in a Validation-Cohort from a different site. Results: 90-patients (56% with APAP) were included in the Derivation-Cohort. Median FV was significantly higher in TFS versus those who died/LT (31% vs. 15%, respectively; p = 0.001). When dichotomized by etiology, AUROC for FV was 0.77 for APAP (cutoff, sensitivity, specificity 10.5%, 79%, 69%, respectively) and 0.77 for non-APAP (22%, 85%, 67%, respectively). When the optimal cutoffs for FV in the Derivation-Cohort were applied to the Validation-Cohort (N = 51; 59% with APAP), AUROC for FV was 0.75 for APAP (sensitivity/specificity 81/44) and 0.95 for non-APAP (sensitivity/specificity 90/73). In multivariate analyses, AUROC for FV model was 0.86 in the Derivation-Cohort and 0.90 in the Validation-Cohort. Conclusion: Admission FV may improve selection of patients who are likely to improve without LT.Item Admission plasma uromodulin and the risk of acute kidney injury in hospitalized patients with cirrhosis: a pilot study(American Physiological Society, 2019-10-01) Patidar, Kavish R.; Garimella, Pranav S.; Macedo, Etienne; Slaven, James E.; Ghabril, Marwan S.; Weber, Regina E.; Anderson, Melissa; Orman, Eric S.; Nephew, Lauren D.; Desai, Archita P.; Chalasani, Naga; El-Achkar, Tarek M.; Medicine, School of MedicineAcute kidney injury (AKI) is a common complication in hospitalized patients with cirrhosis. Uromodulin, a protein uniquely produced by the kidney and released both in the urine and circulation, has been shown to regulate AKI and is linked to tubular reserve. Although low levels of urine uromodulin are associated with AKI after cardiac surgery, it is unclear whether circulating uromodulin can stratify the risk of AKI, particularly in a susceptible population such as hospitalized patients with cirrhosis. Thus, we investigated whether plasma uromodulin measured at the time of admission is associated with subsequent hospital-acquired AKI (defined by a rise in serum creatinine >0.3mg/dL within 48 h or ≥ 1.5 times baseline) in patients with cirrhosis. A total of 98 patients [mean age 54 yr, Model for Endstage Liver Disease Sodium (MELD-Na) score 19, and baseline creatinine of 0.95 mg/dL] were included, of which 13% (n = 13) developed AKI. Median uromodulin levels were significantly lower in patients who developed AKI compared with patients who did not (9.30 vs. 13.35 ng/mL, P = 0.02). After adjusting for age, sex, diabetes, hypertension, albumin, and MELD-Na score as covariates on multivariable logistic regression, uromodulin was independently associated with AKI [odd ratios of 1.19 (95% confidence interval 1.02, 1.37; P = 0.02)]. Lower uromodulin levels on admission are associated with increased odds of subsequent AKI in hospitalized patients with cirrhosis. Further studies are needed to better understand the role of uromodulin in the pathogenesis and as a predictive biomarker of AKI in this population. NEW & NOTEWORTHY In this study, we found that admission plasma uromodulin levels are significantly lower in patients who developed subsequent acute kidney injury (AKI) during their hospital stay compared with patients who did not. Additionally, uromodulin is independently associated with AKI development after adjusting for clinically relevant parameters such as age, sex, diabetes, hypertension, severity of cirrhosis, and kidney function. To our knowledge, this is the first study linking plasma uromodulin with AKI development in patients with cirrhosis.Item Alcohol Use Trajectories after High School Graduation among Emerging Adults with Type 1 Diabetes(Elsevier, 2014-08) Hanna, Kathleen M.; Stupiansky, Nathan W.; Weaver, Michael T.; Slaven, James E.; Stump, Timothy E.; IU School of NursingObjective Explore alcohol involvement trajectories and associated factors during the year post-high school (HS) graduation among emerging adults with type 1 diabetes. Methods Youth (N=181) self-reported alcohol use at baseline and every 3 months for 1 year post-HS graduation. Data were also collected on parent-youth conflict, diabetes self-efficacy, major life events, living and educational situations, diabetes management, marijuana use, cigarette smoking, and glycemic control. Trajectories of alcohol use were modeled using latent class growth analysis. Associations between trajectory class and specific salient variables were examined using analysis of variance, chi square, or generalized linear mixed model, as appropriate. Results Identified alcohol involvement trajectory classes were labeled as: 1) Consistent Involvement Group (n=25, 13.8%) with stable, high use relative to other groups over the 12 months; 2) Growing Involvement Group (n=55, 30.4%) with increasing use throughout the 12 months; and 3) Minimal Involvement Group (n=101, 55.8%) with essentially no involvement until month nine. Those with minimal involvement had the best diabetes management and better diabetes self-efficacy than those with consistent involvement. In comparison to those minimally involved, those with growing involvement were more likely to live independently of parents; those consistently involved had more major life events; and both the growing and consistent involvement groups were more likely to have tried marijuana and cigarettes. Conclusions This sample of emerging adults with type 1 diabetes has 3 unique patterns of alcohol use during the first year after high school. Implication and Contribution Among youth with type 1 diabetes in the year post-HS graduation, alcohol involvement knowledge was extended by identifying patterns of such use. Further research of alcohol use patterns is needed to guide health care professionals in their assessments and researchers in testing interventions that target unique patterns.Item Antenatal corticosteriods decrease forced vital capacity in infants born fullterm(Wiley, 2020-10) Bandyopadhyay, Anuja; Slaven, James E.; Evrard, Cindy; Tiller, Christina; Haas, David M.; Tepper, Robert S.; Pediatrics, School of MedicineAntenatal corticosteroids (ACS) administration to pregnant women for threatened preterm labor is standard obstetric care to reduce neonatal respiratory distress syndrome and the associated respiratory morbidity. While ACS stimulates surfactant production in the fetal lung, the effects of ACS upon the subsequent growth and development of the lung are unclear. Follow-up studies outside of the neonatal period have been primarily limited to spirometry, and most subjects evaluated were born prematurely. To our knowledge, no study has assessed both airway and parenchymal function in infants or adults following ACS exposure. We hypothesized that ACS impairs lung growth and performed infant pulmonary function testing, which included spirometry, alveolar volume (VA ) and lung diffusion (DL ). As a pilot study, we limited our assessment to infants whose mothers received ACS for threatened preterm labor, but then proceeded to full term delivery. This approach evaluated a more homogenous population and eliminated the confounding effects of preterm birth. We evaluated 36 full-term infants between 4 to 12 months of age; 17 infants had ACS exposure and 19 infants had no ACS exposure. Infants exposed to ACS had a significantly lower forced vital capacity compared with non-ACS exposed infants (250 vs 313 mL; P = .0075). FEV0.5 tended to be lower for the ACS exposed group (205 vs 237 mL; P = .075). VA and DL did not differ between the two groups. These findings suggest that ACS may impair subsequent growth of the lung parenchyma.Item Antibiotic Regimen Changes during Cystic Fibrosis Pediatric Pulmonary Exacerbation Treatment(American Thoracic Society, 2023) Cogen, Jonathan D.; Sanders, Don B.; Slaven, James E.; Faino, Anna V.; Somayaji, Ranjani; Gibson, Ron L.; Hoffman, Lucas R.; Ren, Clement L.; Biostatistics and Health Data Science, Richard M. Fairbanks School of Public HealthRationale/Objectives: Antibiotic selection for in-hospital treatment of pulmonary exacerbations (PEx) in people with cystic fibrosis (CF) is typically guided by previous respiratory culture results or past PEx antibiotic treatment. In the absence of clinical improvement during PEx treatment, antibiotics are frequently changed in search of a regimen that better alleviates symptoms and restores lung function. The clinical benefits of changing antibiotics during PEx treatment are largely uncharacterized. Methods: This was a retrospective cohort study using the Cystic Fibrosis Foundation Patient Registry Pediatric Health Information System. PEx were included if they occurred in children with CF from 6 to 21 years old who had been treated with intravenous antibiotics between January 1, 2006, and December 31, 2018. PEx with lengths of stay <5 or >21 days or for which treatment was delivered in an intensive care unit were excluded. An antibiotic change was defined as the addition or subtraction of any intravenous antibiotic between Hospital Day 6 and the day before hospital discharge. Inverse probability of treatment weighting was used to adjust for disease severity and indication bias, which might influence a decision to change antibiotics. Results: In all, 4,099 children with CF contributed 18,745 PEx for analysis, of which 8,169 PEx (43.6%) included a change in intravenous antibiotics on or after Hospital Day 6. The mean change in pre- to post-treatment percent predicted forced expiratory volume in 1 second (ppFEV1) was 11.3 (standard error, 0.21) among events in which an intravenous antibiotic change occurred versus 12.2 (0.18) among PEx without an intravenous antibiotic change (P = 0.001). Similarly, the odds of return to ⩾90% of baseline ppFEV1 were less for PEx with antibiotic changes than for those without changes (odds ratio [OR], 0.89 [95% confidence interval (CI), 0.80–0.98]). The odds of returning to ⩾100% of baseline ppFEV1 did not differ between PEx with versus without antibiotic changes (OR, 0.94 [95% CI, 0.86–1.03]). In addition, PEx treated with intravenous antibiotic changes were associated with higher odds of future PEx (OR, 1.17 [95% CI, 1.12–1.22]). Conclusions: In this retrospective study, changing intravenous antibiotics during PEx treatment in children with CF was common and not associated with improved clinical outcomes.Item Assessing the impact of a primary care electronic medical record system in three Kenyan rural health centers(Oxford University Press, 2016-05) Tierney, William M.; Sidle, John E.; Diero, Lameck O.; Sudoi, Allan; Kiplagat, Jepchirchir; Macharia, Stephen; Shen, Changyu; Yeung, Ada; Were, Martin C.; Slaven, James E.; Wools-Kaloustian, Kara; Medicine, School of MedicineObjective: Efficient, effective health care requires rapid availability of patient information. We designed, implemented, and assessed the impact of a primary care electronic medical record (EMR) in three rural Kenyan health centers. Method: Local clinicians identified data required for primary care and public health reporting. We designed paper encounter forms to capture these data in adult medicine, pediatric, and antenatal clinics. Encounter form data were hand-entered into a new primary care module in an existing EMR serving onsite clinics serving patients infected with the human immunodeficiency virus (HIV). Before subsequent visits, Summary Reports were printed containing selected patient data with reminders for needed HIV care. We assessed effects on patient flow and provider work with time-motion studies before implementation and two years later, and we surveyed providers' satisfaction with the EMR. Results: Between September 2008 and December 2011, 72 635 primary care patients were registered and 114 480 encounter forms were completed. During 2011, 32 193 unique patients visited primary care clinics, and encounter forms were completed for all visits. Of 1031 (3.2%) who were HIV-infected, 85% received HIV care. Patient clinic time increased from 37 to 81 min/visit after EMR implementation in one health center and 56 to 106 min/visit in the other. However, outpatient visits to both health centers increased by 85%. Three-quarters of increased time was spent waiting. Despite nearly doubling visits, there was no change in clinical officers' work patterns, but the nurses' and the clerks' patient care time decreased after EMR implementation. Providers were generally satisfied with the EMR but desired additional training. Conclusions: We successfully implemented a primary care EMR in three rural Kenyan health centers. Patient waiting time was dramatically lengthened while the nurses' and the clerks' patient care time decreased. Long-term use of EMRs in such settings will require changes in culture and workflow.Item Assessment of Discordance Between Surrogate Care Goals and Medical Treatment Provided to Older Adults With Serious Illness(JAMA Network, 2020-05) Comer, Amber R.; Hickman, Susan E.; Slaven, James E.; Monahan, Patrick O.; Sachs, Greg A.; Wocial, Lucia D.; Burke, Emily S.; Torke, Alexia M.; Health Sciences, School of Health and Human SciencesImportance: An important aspect of high-quality care is ensuring that treatments are in alignment with patient or surrogate decision-maker goals. Treatment discordant with patient goals has been shown to increase medical costs and prolong end-of-life difficulties. Objectives: To evaluate discordance between surrogate decision-maker goals of care and medical orders and treatments provided to hospitalized, incapacitated older patients. Design, setting, and participants: This prospective cohort study included 363 patient-surrogate dyads. Patients were 65 years or older and faced at least 1 major medical decision in the medical and medical intensive care unit services in 3 tertiary care hospitals in an urban Midwestern area. Data were collected from April 27, 2012, through July 10, 2015, and analyzed from October 5, 2018, to December 5, 2019. Main outcomes and measures: Each surrogate's preferred goal of care was determined via interview during initial hospitalization and 6 to 8 weeks after discharge. Surrogates were asked to select the goal of care for the patient from 3 options: comfort-focused care, life-sustaining treatment, or an intermediate option. To assess discordance, the preferred goal of care as determined by the surrogate was compared with data from medical record review outlining the medical treatment received during the target hospitalization. Results: A total of 363 dyads consisting of patients (223 women [61.4%]; mean [SD] age, 81.8 [8.3] years) and their surrogates (257 women [70.8%]; mean [SD] age, 58.3 [11.2] years) were included in the analysis. One hundred sixty-nine patients (46.6%) received at least 1 medical treatment discordant from their surrogate's identified goals of care. The most common type of discordance involved full-code orders for patients with a goal of comfort (n = 41) or an intermediate option (n = 93). More frequent in-person contact between surrogate and patient (adjusted odds ratio [AOR], 0.43; 95% CI, 0.23-0.82), patient residence in an institution (AOR, 0.44; 95% CI, 0.23-0.82), and surrogate-rated quality of communication (AOR, 0.98; 95% CI, 0.96-0.99) were associated with lower discordance. Surrogate marital status (AOR for single vs married, 1.92; 95% CI, 1.01-3.66), number of family members involved in decisions (AOR for ≥2 vs 0-1, 1.84; 95% CI, 1.05-3.21), and religious affiliation (AOR for none vs any, 4.87; 95% CI, 1.12-21.09) were associated with higher discordance. Conclusions and relevance: This study found that discordance between surrogate goals of care and medical treatments for hospitalized, incapacitated patients was common. Communication quality is a modifiable factor associated with discordance that may be an avenue for future interventions.
