Electronic Consultations in a Community Neurology Practice: A Retrospective Study Informing Best Practice.

Objective: To describe our practice of electronic consultations (e-consults) and assess safety and risk factors for subsequent face-to-face consultations. Patients and Methods: A retrospective cohort study of all e-consults completed in a community neurology practice between May 5, 2018, and June 31, 2019, was completed. Clinical and demographic variables were compared between the successful and unsuccessful (defined by presence of subsequent face-to-face consultation) cohorts. Hazard ratios (HR) were calculated using Cox regression model. Kaplan-Meier probability analysis (with 95% CIs) of subsequent face-to-face consultation was performed. Case examples highlighting potential harm were summarized. Results: In total, 302 e-consults were reviewed. The most frequent referrals were for headache (n=125, 41.4%), dysesthesia (n=40, 13.2%), and abnormal imaging finding (n=27, 8.9%). The most common e-consult questions were for treatment (57.6%) and diagnostic evaluation (48.0%) recommendations. Moreover, 24.8% (n=75) of e-consults were followed by face-to-face consultations, with primary risk factors including female sex (HR, 1.9), referral for headache (HR, 1.7), and final diagnosis of migraine (HR, 2.0) or long-term migraine (HR, 5.0). Potential harm related to delayed diagnosis/treatment was identified in 6 (2.0%) patients with migraine and 4 (1.3%) without migraine presenting to emergency department. Conclusion: Utilization of e-consults may safely improve access to neurologic expertise and prevent the need for some visits, which may have required a face-to-face visit. In patients with chronic migraine, e-consults should be considered short-term and followed by face-to-face consultation as soon as access allows. Neurologists performing e-consults should be able to triage patients to face-to-face consultation, particularly when diagnosis is uncertain or the neurologic examination may help guide appropriate testing.

Population Based Time Trends in the Epidemiology and Mortality of Gastroesophageal Junction and Esophageal Adenocarcinoma.

BACKGROUND: Limited data are available on the epidemiology of gastroesophageal junction adenocarcinoma (GEJAC), particularly in comparison to esophageal adenocarcinoma (EAC). With the advent of molecular non-endoscopic Barrett's esophagus (BE) detection tests which sample the esophagus and gastroesophageal junction, early detection of EAC and GEJAC has become a possibility and their epidemiology has gained importance. AIMS: We sought to evaluate time trends in the epidemiology and survival of patients with EAC and GEJAC in a population-based cohort. METHODS: EAC and GEJAC patients from 1976 to 2019 were identified using ICD 9 and 10 diagnostic codes from the Rochester Epidemiology Project (REP). Clinical data and survival status were abstracted. Poisson regression was used to calculate incidence rate ratios (IRR). Survival analysis and Cox proportional models were used to assess predictors of survival. RESULTS: We included 443 patients (287 EAC,156 GEJAC). The incidence of EAC and GEJAC during 1976-2019 was 1.40 (CI 1.1-1.74) and 0.83 (CI 0.61-1.11) per 100,000 people, respectively. There was an increase in the incidence of EAC (IRR = 2.45, p = 0.011) and GEJAC (IRR = 3.17, p = 0.08) from 2000 to 2004 compared to 1995-1999, plateauing in later time periods. Most patients had associated BE and presented at advanced stages, leading to high 5-year mortality rates (66% in EAC and 59% in GEJAC). Age and stage at diagnosis were predictors of mortality. CONCLUSION: The rising incidence of EAC/GEJAC appears to have plateaued somewhat in the last decade. However, both cancers present at advanced stages with persistently poor survival, underscoring the need for early detection.

The natural history of histological changes in microscopic colitis.

Background: Microscopic colitis (MC) causes chronic diarrhea. It has two histologic subtypes: lymphocytic colitis (LC) and collagenous colitis (CC). Little is known about the natural progression of disease with time and with treatment. Objectives: We aimed to assess histological changes over time. Design: We designed a retrospective study including adults diagnosed with MC from January 1992 to January 2020 at Mayo Clinic. Methods: Pathology reports were reviewed until 31 October 2020. Histological assessments at least 8 weeks apart were considered as adequate follow-up. Histological change from one subtype to the other and resolution were tracked with univariate and multivariable Cox proportional hazards models. Results: Overall, 416 patients with a median age at diagnosis of 63.9 years with >1 histopathological assessment were identified. Histology at initial diagnosis was CC in 218 (52.4%) patients and LC in 198 (47.6%). No medications were associated with a histological change. However, histological resolution was more likely with the use of aspirin [hazard ratio (HR): 2.10, 95% confidence interval (CI): 1.34-3.31, p = 0.001) and proton-pump inhibitors (PPIs; HR: 2.01, 95% CI: 1.34-3.02, p = 0.001). Histological resolution was more likely with budesonide treatment (HR: 1.86, 95% CI: 1.16-3.00, p = 0.010) and less likely with mesalamine (HR: 0.40, 95% CI: 0.19-0.83, p = 0.014), compared to medications such as prednisone, loperamide, and bismuth. Patients with CC were less likely to change their histology compared to patients with LC (HR: 0.24, 95% CI: 0.14-0.42, p < 0.001). There was no difference in histological resolution between the two subtypes (HR: 0.70, 95% CI: 0.47-1.05, p = 0.084). Conclusion: Patients with LC have a higher chance of changing their histology as compared to CC. However, histological resolution was associated with the use of PPIs and aspirin, and treatment with budesonide.

ROAR ED-SANE: A Retrospective Observational Assessment Review of an Emergency Department Sexual Assault Nurse Examiner Program's Adherence to Centers for Disease Control and Prevention Guidelines for Sexually Transmitted Infections.

BACKGROUND: Sexual assault survivors are at increased risk for sexually transmitted infections. Sexual Assault Nurse Examiner programs guide sexually transmitted infection treatment, monitoring, and follow-up scheduling according to guidelines by the Centers for Disease Control and Prevention (CDC). Reported low rates of provider adherence to CDC treatment guidelines and patient adherence to follow-up necessitate a review of medication prescribing and follow-up scheduling practices, especially at smaller community hospitals in the United States. METHODS: A retrospective medical record review was conducted to assess adherence rates to CDC guidelines for prescribing practices, scheduling, and follow-up of sexual assault survivors. We included pediatric and adult patients presenting to the emergency department (ED) and participating in the ED Sexual Assault Nurse Examiner program at a rural, community-based teaching hospital in La Crosse, WI, from January 2018 to December 2021. Descriptive statistics were used to evaluate results. RESULTS: Analysis included 103 patients. Prescribing adherence to CDC guidelines was >80% for all except human immunodeficiency virus (53.4%), trichomoniasis (68.1%), and hepatitis B (69%). Of the 38 patients who had a follow-up scheduled during their ED encounter, 78.9% attended their scheduled follow-up and 94.7% of those appointments were scheduled within the CDC-recommended time frame, leading to an overall adherence of 40%. CONCLUSIONS: Adherence rates were high for most prescribing practices, and attendance of scheduled follow-up was higher than expected. Opportunities to improved adherence to CDC guidelines were identified in prescribing for 3 disease states (human immunodeficiency virus, trichomoniasis, and hepatitis B) and in scheduling of follow-up.

Change in serial liver stiffness measurement by magnetic resonance elastography and outcomes in NAFLD.

BACKGROUND AND AIMS: The impact of disease progression in NAFLD on liver outcomes remains poorly understood. We aimed to investigate NAFLD progression using longitudinal liver stiffness measurements (LSM) by serial magnetic resonance elastography (MRE) and the association with liver outcomes. APPROACH AND RESULTS: All adult patients with NAFLD who underwent at least two serial MREs for clinical evaluation at Mayo Clinic, Rochester, between 2007 and 2019 were identified from the institutional database. Progression and regression were defined based on LSM change of 19% above or below 19% of initial LSM, respectively, based on Quantitative Imaging Biomarker Alliance consensus. The association between change in LSM and liver-related outcomes occurring after the last MRE was examined using time-to-event analysis. A total of 128 participants underwent serial MREs (53% female, median age 59 years). The median time between paired MREs was 3.4 (range 1-10.7) years. NAFLD progression (LSM = +0.61 kPa/year) was identified in 17 patients (13.3%). NAFLD regression (-0.40 kPa/year) occurred in 35 patients (27.3%). Stable LSM was noted in 76 participants (59.4%). In NAFLD without cirrhosis at baseline ( n = 75), cirrhosis development occurred in 14% of LSM progressors and 2.9% of non-progressors ( p = 0.059) over a median 2.7 years of follow-up from the last MRE. Among those with compensated cirrhosis at baseline MRE ( n = 29), decompensation or death occurred in 100% of LSM progressors and 19% of non-progressors ( p < 0.001) over a median 2.5 years of follow-up after the last MRE. CONCLUSIONS: Noninvasive monitoring of LSM by conventional MRE is a promising method of longitudinal NAFLD monitoring and risk estimation of liver-related outcomes in NAFLD.

Prevalence and Categorization of Drug-Related Problems in the Emergency Department.

BACKGROUND: Drug-related problems (DRPs) are common among patients seen in the emergency department (ED), but the true incidence is not clear. OBJECTIVES: The primary objective of this study was to determine the prevalence of DRPs among patients seen in a U.S. ED. The secondary objective was to categorize these DRPs by problem type and by medication class. METHODS: This was a prospective observational cohort study of a random sample of ED patients between December 2011 and March 2013. ED pharmacists screened randomly selected patients for the presence of a DRP contributing to the ED visit. Four independent auditors evaluated the results to achieve consensus for the presence or absence of DRPs and categorization of the DRPs. RESULTS: Among 1039 patients screened for DRPs, 308 (29.6%) were found to have at least 1 DRP contributing to the ED visit. Among a total of 443 DRPs, the most commonly identified categories were adverse drug reaction (n = 193 [43.6%]), ineffective medication (n = 69 [15.6%]), and subtherapeutic dosage (n = 68 [15.3%]). The most commonly implicated drug classes were cardiovascular medications (n = 113 [26.5%]), anti-infective medications (n = 52 [12.2%]), and analgesic medications (n = 58 [13.6%]). CONCLUSIONS: A substantial proportion of ED visits are associated in part or in total with DRPs. Adverse drug reactions and cardiovascular medications are the most common category and medication class implicated, respectively.

Evaluation of an initiative to improve prophylactic antimicrobial prescribing in patients on extracorporeal membrane oxygenation (ECMO) through the application of three antimicrobial-spectrum scores.

Antimicrobial spectrum scoring is a method to quantify the spectrum of antimicrobial utilization. Herein, we applied a locally adapted scoring system, with other pre-existing scoring systems, using a data set of prophylactically administered antibiotics following a 2-stage antimicrobial stewardship program (ASP) intervention in a population of patients on extracorporeal membrane oxygenation (ECMO).

Magnetic resonance elastography for prediction of long-term progression and outcome in chronic liver disease: A retrospective study.

BACKGROUND AND AIMS: Although magnetic resonance elastography (MRE) has been well-established for detecting and staging liver fibrosis, its prognostic role in determining outcomes of chronic liver disease (CLD) is mostly unknown. APPROACH AND RESULTS: This retrospective study consisted of 1269 subjects who underwent MRE between 2007 and 2009 and followed up until death or last known clinical encounter or end of study period. Charts were reviewed for cirrhosis development, decompensation, and transplant or death. The cohort was split into baseline noncirrhosis (group 1), compensated cirrhosis (group 2), and decompensated cirrhosis (group 3). Cox-regression analysis with age, sex, splenomegaly, CLD etiology, Child-Pugh Score (CPS), Fibrosis-4 Index (FIB-4) score, and Model for End-Stage Liver Disease (MELD)-adjusted HR for every 1-kPa increase in liver stiffness measurement (LSM) were used to assess the predictive performance of MRE on outcomes. Group 1 (n = 821) had baseline median LSM of 2.8 kPa, and cirrhosis developed in 72 (8.8%) subjects with an overall rate of about 1% cirrhosis/year. Baseline LSM predicted the future cirrhosis with multivariable adjusted HR of 2.38 (p < 0.0001) (concordance, 0.84). In group 2 (n = 277) with baseline median LSM of 5.7 kPa, 83 (30%) subjects developed decompensation. Baseline LSM predicted the future decompensation in cirrhosis with FIB-4 and MELD-adjusted HR of 1.22 (p < 0.0001) (concordance, 0.75). In group 3 (n = 171) with median baseline LSM of 6.8 kPa (5.2, 8.4), 113 (66%) subjects had either death or transplant. Baseline LSM predicted the future transplant or death with HR of 1.11 (p = 0.013) (concordance 0.53) but not in CPS and MELD-adjusted models (p = 0.08). CONCLUSION: MRE-based LSM is independently predictive of development of future cirrhosis and decompensation, and has predictive value in future transplant/death in patients with CLD.

Malignancy among adult heart transplant recipients following patient-tailored dosing of anti-thymocyte globulin: a retrospective, nested case-control study of individualized dosing.

Post-transplant malignancy is diagnosed in approximately 18% of heart transplant patients and is a leading cause of death post-transplant. One modifiable risk factor is the type and amount of immunosuppression received. Contemporary rabbit anti-thymocyte globulin (rATG) dosing strategy using T-cell-guided dosing, and its effect on malignancy in heart transplant patients is unclear. This was a single-center, retrospective chart review of heart transplant recipients receiving rATG for induction. Patients diagnosed with malignancy post-transplant were matched 1:2 to controls using a nested case-control design. The primary endpoint was to determine the relative risk of rATG exposure with the actual incidence of malignancy post-transplant. The secondary endpoint was the impact of maintenance immunosuppression on malignancy risk. Of the 126 patients included in the study, 25 developed malignancy and were matched to 50 control patients. The median cumulative rATG dose in milligrams (mg) between groups was 365 mg in malignancy cases and 480 mg in controls (OR 0.90, 95% CI 0.75-1.08, P = 0.28). In both the univariate and multivariable analysis, there was no statistically significant difference in malignancy risk found with any maintenance immunosuppressant. The results of this study showed that patient-tailored rATG dosing strategies may not be associated with malignancy development as previously thought.

Effect of Pharmacist Audit on Antibiotic Duration for Pneumonia and Urinary Tract Infection.

OBJECTIVE: To assess the effect of clinical pharmacists in daily audits, under the direction of an antimicrobial stewardship program, of antibiotic treatment durations for the common inpatient disease states of community-acquired pneumonia (CAP) and urinary tract infection (UTI). PATIENTS AND METHODS: This was a retrospective single-center cohort study that evaluated the difference in the duration of antibiotic therapy for CAP or non-catheter-associated UTI of hospitalized patients who received a daily audit by clinical pharmacists compared with patients who did not receive a daily audit. Retrospective chart review included randomly selected hospitalized patients diagnosed with CAP or UTI during preaudit and postaudit periods. RESULTS: The preaudit group had 64 patients; and the postaudit group, 51 patients. The therapy duration was 7 days in the preaudit group and 6 days in the postaudit group (P=.55). Fluoroquinolone use was reduced in the postaudit group and was significantly less than in the preaudit group (24 [37.5%] vs 7 [13.7%]; P=.007). CONCLUSION: The daily audits of clinical pharmacists may be an effective method to reduce the duration of antibiotic therapy and are effective in the reduction of fluoroquinolone use. Additional studies must be done to further investigate the effects of clinical pharmacist antimicrobial stewardship efforts.

Effect of an Integrated Clinical Pharmacist on the Drivers of Provider Burnout in the Primary Care Setting.

PURPOSE: As the prevalence of provider burnout continues to increase, it is critical to identify interventions that may impact provider satisfaction, such as an integrated clinical pharmacist. This study aimed to assess the perceived effect of pharmacist integration on primary care provider satisfaction and drivers of provider burnout in the primary care setting. METHODS: A cross-sectional survey with 11 questions across 4 domains was distributed to primary care providers in a large integrated health system. RESULTS: Of 295 providers invited to take the survey, 119 responded (40% response rate). Most providers had worked with a pharmacist for at least 2 years and utilized them weekly or daily. At least 87% of provider respondents strongly agreed or somewhat agreed that the integrated clinical pharmacist reduced their workload by working directly with patients and non-provider staff, improved overall medication use, helped patients meet health goals and quality measures, and overall helped them to effectively manage their panel of patients. Providers found greater meaning in work through the presence of the clinical pharmacist, which allowed them more time to focus on professionally fulfilling aspects of their work and helped them feel less emotional exhaustion. Overall, 91% of providers were extremely satisfied with the clinical pharmacy service. CONCLUSIONS: These findings may be used to justify the expansion of clinical pharmacy services in primary care to practice areas experiencing problems with 4 specific drivers of provider burnout: workload and job demands, efficiency and resources, meaning in work, and social support and community at work.

Early, empiric high-dose leucovorin rescue in lymphoma patients treated with sequential doses of high-dose methotrexate.

BACKGROUND: In patients exposed to high-dose methotrexate (HDMTX; >1g/m2) with a history of elevated methotrexate (MTX) concentrations during previous doses, it is unclear whether prescribing high-dose leucovorin (HDLV) rescue limits future high levels or reduces the likelihood of acute kidney injury (AKI). METHODS: This retrospective, single-center study longitudinally followed adult lymphoma patients treated with HDMTX between 1/1/2011 and 10/31/2017 from diagnosis until 30 days after the last HDMTX dose. Endpoints included elevated MTX concentrations at 48 h (>1.0 µmol/L) and incident AKI after each HDMTX dose. RESULTS: The 321 included patients had a median (IQR) age of 65 (57, 72) years, 190 (59%) were male, and 293 (91%) were Caucasian. There were 1558 HDMTX doses [median (IQR) 3 (2, 6) doses per patient] prescribed with 265 (83%) patients receiving more than one MTX dose. Those receiving HDLV rescue were more likely to have an elevated MTX concentration after that dose (OR = 2.69, 95% CI: 1.75-4.11, p < 0.001). Receiving HDLV rescue was associated with a greater likelihood of AKI after MTX (OR = 2.18, 95% CI: 1.38-3.43, p < 0.001). Hospital LOS was longer in those prescribed empiric HDLV rescue after MTX than those prescribed standard leucovorin with an estimated difference of 1.1 days, (95% CI: 0.5-1.7, p < 0.001). CONCLUSION: Sequential HDMTX doses are associated with a significant incidence of elevated MTX levels and AKI during lymphoma management. HDLV rescue prescribed during subsequent MTX doses in patients with a previously elevated level was not associated with improved safety outcomes. The optimal supportive care strategy following HDMTX administration requires further investigation.

Characteristics and Outcome of Periengraftment Respiratory Distress Syndrome after Autologous Hematopoietic Cell Transplant.

Rationale: The periengraftment respiratory distress syndrome (PERDS) is an early important cause of morbidity following autologous hematopoietic cell transplantation (HCT). There are few contemporary data describing PERDS. Objectives: To determine prevalence, risk factors, and outcomes of PERDS after autologous HCT. Methods: This was a historical cohort study of adults undergoing autologous HCT at Mayo Clinic, Rochester, Minnesota, between 2005 and 2016. PERDS was defined as 1) respiratory failure requiring supplemental oxygen within 5 days on either side of the neutrophil engraftment date, 2) new pulmonary opacities on chest imaging, and 3) exclusion of an infectious or cardiac etiology to explain the clinical presentation. Results: Of 3,473 patients undergoing autologous HCT, 167 (4.8%) developed PERDS. Radiographic changes preceded engraftment in 77% of cases. In a multivariable regression model, risk factors for PERDS included female sex (odds ratio [OR], 1.73; P = 0.001), the number of preengraftment platelet transfusions (OR, 1.22; P = 0.002), and more rapid engraftment (OR, 0.72 per day longer; P < 0.001). PERDS cases were more likely to be admitted to the intensive care unit (47.3% vs. 9.5%, P < 0.001) and require intubation (20.4% vs. 1.6%, P < 0.001). In an adjusted 100-day death analysis, those diagnosed with PERDS were more likely to die (hazard ratio, 3.1; 95% confidence interval, 1.5-6.2; P = 0.002). Conclusions: PERDS is a common complication of autologous HCT and is associated with increased mortality and healthcare use. Radiographic evidence of pulmonary involvement precedes hematopoietic recovery. A larger number of platelet transfusions and more rapid engraftment appear to increase risk for PERDS.

Outcomes of radiofrequency ablation by manual versus self-sizing circumferential balloon catheters for the treatment of dysplastic Barrett's esophagus: a multicenter comparative cohort study.

BACKGROUND AND AIMS: Radiofrequency ablation (RFA) is the preferred ablative modality for treating dysplastic Barrett's esophagus. The recently introduced self-sizing circumferential ablation catheter eliminates the need for a sizing balloon. Although it enhances efficiency, outcomes have not been compared with the previous manual-sizing catheter. We evaluated the comparative safety and efficacy of these 2 ablation systems in a large, multicenter cohort. METHODS: Patients undergoing RFA at 3 tertiary care centers from 2005 to 2018 were included. Circumferential RFA was performed in a standard fashion, followed by focal RFA as needed. Outcomes were compared between the self-sizing and manual-sizing groups. The primary outcome was the rate of adverse events, including strictures, perforation, and bleeding. Secondary outcomes were procedure time and treatment efficacy, as assessed by rates and time to complete eradication of dysplasia (CE-D) and intestinal metaplasia (CE-IM). RESULTS: Three hundred eighteen patients were included, 90 (28.3%) treated with the self-sizing catheter and 228 (71.7%) with the manual-sizing catheter. Twenty-one patients (6.6%) developed strictures (8 [8.9%] in the self-sizing group and 13 [5.7%] in the manual-sizing group, P = .32). Of the self-sizing strictures, 75% occurred at the 12J dose before widespread adoption of the current 10J treatment standard. One patient developed bleeding, and no perforations were encountered. Procedure time was significantly shorter in the self-sizing group. No significant differences were observed in rates of and time to CE-D and CE-IM. CONCLUSIONS: These findings suggest that both systems are comparable in safety and efficacy. The use of the self-sizing system may enhance the efficiency of RFA for treating dysplastic Barrett's esophagus.

Pharmacist-Driven MRSA Nasal PCR Screening and the Duration of Empirical Vancomycin Therapy for Suspected MRSA Respiratory Tract Infections.

OBJECTIVE: To assess the effect of a pharmacist-driven, polymerase chain reaction (PCR)-based nasal screening protocol for methicillin-resistant Staphylococcus aureus (MRSA) on vancomycin therapy duration and on rates of adverse drug events and 30-day hospital readmission. PATIENTS AND METHODS: From July 8, 2017, through January 31, 2019, we performed a retrospective, multicenter, preimplementation-postimplementation study. Patients with a vancomycin order to treat lower respiratory tract infection (LRTI) underwent MRSA PCR screening; tests were ordered by health care providers, including physicians, physician assistants, and advanced practice registered nurses. During the preimplementation period (July 8, 2017, through September 30, 2018), pharmacists could order MRSA PCR screening only after receiving a verbal order from a health care provider. During the postimplementation period (October 1, 2018, through January 31, 2019), a collaborative practice agreement allowed pharmacists to order MRSA PCR screening tests. RESULTS: The preimplementation group included 241 patients, and the postimplementation group included 74 patients. Of these patients, 124 in the preimplementation group and 62 in the postimplementation group received MRSA PCR screening. Twenty patients (16.1%) in the preimplementation group and 9 (14.5%) in the postimplementation group had a positive MRSA PCR screening test result (between-group difference, 1.6%; P=.80). Duration of therapy was significantly shorter in the postimplementation group (median [interquartile range], 14.3 [5.0-28.6] hours vs 24.0 [12.4-47.0] hours; P<.001). CONCLUSION: Vancomycin therapy carries a risk of adverse events and may increase health care costs. A pharmacist-driven protocol for MRSA nasal swab PCR screening effectively reduces the duration of vancomycin therapy for patients with lower respiratory tract infection.

Provision of a Drug Deactivation System for Unused Opioid Disposal at Surgical Dismissal: Opportunity to Reduce Community Opioid Supply.

OBJECTIVE: To determine the impact of a drug deactivation system to post-surgical patients on the rate of opioid prescription disposal. PATIENTS AND METHODS: Two hundred post-operative patients discharged after inpatient surgery at a large academic medical center. This study was conducted August 20, 2018, through November 30, 2018. Patients were provided with a drug deactivation system (DDS) and instruction sheet along with their opioid prescription. Three to 4 weeks after dismissal, patients were surveyed about quantity of opioids remaining, use of DDS or other disposal methods, and satisfaction with DDS if used. RESULTS: One hundred forty-nine of 200 (74.5%) patients were surveyed. One hundred six reported leftover opioids and 29 (27.3%) had disposed of these medications. By the time of survey, 23 (21.2%) participants with leftover opioids had used the DDS to destroy their remaining supply and an additional 33 (31.1%) participants reported plans to use the disposal bag on a future date. Of the 23 participants who used the DDS, 22 (96.0%) reported that they were very satisfied with the disposal process. CONCLUSION: Participants are willing to use a DDS and are satisfied with the process; however, additional education is needed to ensure timely disposal.

A Prospective Survey of Outpatient Medication Adherence in Adult Allogeneic Hematopoietic Stem Cell Transplantation Patients.

Limited data exist regarding the prevalence and outcome of medication nonadherence in the adult allogeneic hematopoietic stem cell transplantation (allo-HSCT) population. The objective of this cross-sectional survey study is to determine the prevalence of medication nonadherence to immunosuppressant and nonimmunosuppressant medications in adult recipients of allo-HSCT. An electronic survey using previously validated medication adherence scales was distributed between December 2014 and April 2015 to 200 adult patients with at least 3 months of follow-up after allo-HSCT. Immunosuppressant serum drug levels and prescription refill records were retrospectively collected to assess correlation with survey responses. In the entire cohort, 51% of subjects (n = 102) reported nonadherence to nonimmunosuppressant medications (95% confidence interval [CI], 44.07% to 57.93%) on the Morisky Medication Adherence Scale. Of the 153 patients taking oral immunosuppressant medications at the time of the survey, 58 (37.9%) reported nonadherence to immunosuppressant therapy (95% CI, 30.22% to 45.6%), as measured by the Immunosuppressant Therapy Adherence Scale. Younger age and distress were associated with medication nonadherence. Nonadherence to immunosuppressant therapy was associated with mild chronic graft-vs-host disease (cGVHD), and a similar trend was observed for moderate cGVHD. Medication nonadherence was found to be highly prevalent for both immunosuppressant and nonimmunosuppressant medications in adult allo-HSCT recipient, and further study to identify interventions to improve adherence in these patients is warranted.

Evaluating a combined bowel preparation for small-bowel capsule endoscopy: a prospective randomized-controlled study.

BACKGROUND: Capsule endoscopy (CE) is frequently hindered by intra-luminal debris. Our aim was to determine whether a combination bowel preparation would improve small-bowel visualization, diagnostic yield, and the completion rate of CE. METHODS: Single-blind, prospective randomized-controlled study of outpatients scheduled for CE. Bowel-preparation subjects ingested 2 L of polyethylene glycol solution the night prior to CE, 5 mL simethicone and 5 mg metoclopramide 20 minutes prior to CE and laid in the right lateral position 30 minutes after swallowing CE. Controls had no solid food after 7 p.m. the night prior to CE and no liquids 4 hours prior to CE. Participants completed a satisfaction survey. Capsule readers completed a small-bowel-visualization assessment. RESULTS: Fifty patients were prospectively enrolled (56% female) with a median age of 54.4 years and 44 completed the study (23 patients in the control group and 21 in the preparation group). There was no significant difference between groups on quartile-based small-bowel visualization (all P > 0.05). There was no significant difference between groups in diagnostic yield (P = 0.69), mean gastric (P = 0.10) or small-bowel transit time (P = 0.89). The small-bowel completion rate was significantly higher in the preparation group (100% vs 78%; P = 0.02). Bowel-preparation subjects reported significantly more discomfort than controls (62% vs 17%; P = 0.01). CONCLUSIONS: Combined bowel preparation did not improve small-bowel visualization but did significantly increase patient discomfort. The CE completion rate improved in the preparation group but the diagnostic yield was unaffected. Based on our findings, a bowel preparation prior to CE does not appear to improve CE performance and results in decreased patient satisfaction (ClinicalTrials.gov, No. NCT01243736).
