Implementing a Telehealth Shared Counseling and Decision-Making Visit for Lung Cancer Screening in a Veterans Affairs Medical Center.

Background: Veterans suffer substantial morbidity and mortality from lung cancer. Lung cancer screening (LCS) with low-dose computed tomography (LDCT) can reduce mortality. Guidelines recommend counseling and shared decision-making (SDM) to address the benefits and harms of screening and the importance of tobacco cessation before patients undergo screening. Observations: We implemented a centralized LCS program at the Iowa City Veterans Affairs Medical Center with a nurse program coordinator (NPC)-led telephone visit. Our multidisciplinary team ensured that veterans referred from primary care met eligibility criteria, that LDCT results were correctly coded by radiology, and that pulmonary promptly evaluated abnormal LDCT. The NPC mailed a decision aid to the veteran and scheduled a SDM telephone visit. We surveyed veterans after the visit using validated measures to assess knowledge, decisional conflict, and quality of decision making. We conducted 105 SDM visits, and 91 veterans agreed to LDCT. Overall, 84% of veterans reported no decisional conflict, and 59% reported high-quality decision making. While most veterans correctly answered questions about the harms of radiation, false-positive results, and overdiagnosis, few knew when to stop screening, and most overestimated the benefit of screening and the predictive value of an abnormal scan. Tobacco cessation interventions were offered to 72 currently smoking veterans. Conclusions: We successfully implemented an LCS program that provides SDM and tobacco cessation support using a centralized telehealth model. While veterans were confident about screening decisions, knowledge testing indicated important deficits, and many did not engage meaningfully in SDM. Clinicians should frame the decision as patient centered at the time of referral, highlight the importance of SDM, and be able to provide adequate decision support.

An Unusual Presentation of Dermatomyositis With Muscle Hypertrophy.

Peripheral nerve hyperexcitability is a rare disorder characterized by spontaneous motor unit activity. Although peripheral nerve hyperexcitability is seen in multiple immune-mediated neurological conditions, an association with dermatomyositis has rarely been reported. We present a 65-year-old woman with serological and muscle biopsy features of dermatomyositis who also developed marked muscle hypertrophy, stiffness, and delayed relaxation along with electrodiagnostic features of peripheral nerve hyperexcitability such as that seen in Isaacs syndrome.

Perception of higher-order affordances for kicking in soccer.

We investigated the perception of higher-order interpersonal affordances for kicking that emerged from lower-order personal and interpersonal affordances in the context of soccer. Youth soccer players reported the minimum gap width between two confederates through which they could kick a ball. In Experiment 1, we independently manipulated the egocentric distance of gaps from participants, and the nominal role of the confederates, either as teammates or opponents. In Experiment 2, we additionally varied the direction in which the confederates were facing, either together (i.e., into the gap) or away (i.e., away from the gap). Perceived minimum kickable gap width was larger for farther egocentric distances, when confederates were identified as opponents rather than as teammates, and (in Experiment 2) when confederates faced toward, rather than away from the gap. In both experiments, these main effects were subsumed in statistically significant interactions. We argue that these interactions reveal perception of higher-order interpersonal affordances for kicking that emerged from the simultaneous influence of lower-order affordances. The results are compatible with the hypothesis that these higher-order affordances were perceived, as such, and were not additively combined from independent perception of underlying, lower-order affordances.

Mortality Among US Veterans Admitted to Community vs Veterans Health Administration Hospitals for COVID-19.

Importance: Veterans Health Administration (VHA) enrollees receive care for COVID-19 in both VHA and non-VHA (ie, community) hospitals, but little is known about the frequency or outcomes of care for veterans with COVID-19 in VHA vs community hospitals. Objective: To compare outcomes among veterans admitted for COVID-19 in VHA vs community hospitals. Design, Setting, and Participants: This retrospective cohort study used VHA and Medicare data from March 1, 2020, to December 31, 2021, on hospitalizations for COVID-19 in 121 VHA and 4369 community hospitals in the US among a national cohort of veterans (aged ≥65 years) enrolled in both the VHA and Medicare with VHA care in the year prior to hospitalization for COVID-19 based on the primary diagnosis code. Exposure: Admission to VHA vs community hospitals. Main Outcomes and Measures: The main outcomes were 30-day mortality and 30-day readmission. Inverse probability of treatment weighting was used to balance observable patient characteristics (eg, demographic characteristics, comorbidity, mechanical ventilation on admission, area-level social vulnerability, distance to VHA vs community hospitals, and date of admission) between VHA and community hospitals. Results: The cohort included 64 856 veterans (mean [SD] age, 77.6 [8.0] years; 63 562 men [98.0%]) dually enrolled in the VHA and Medicare who were hospitalized for COVID-19. Most (47 821 [73.7%]) were admitted to community hospitals (36 362 [56.1%] admitted to community hospitals via Medicare, 11 459 [17.7%] admitted to community hospitals reimbursed via VHA's Care in the Community program, and 17 035 [26.3%] admitted to VHA hospitals). Admission to community hospitals was associated with higher unadjusted and risk-adjusted 30-day mortality compared with admission to VHA hospitals (crude mortality, 12 951 of 47 821 [27.1%] vs 3021 of 17 035 [17.7%]; P < .001; risk-adjusted odds ratio, 1.37 [95% CI, 1.21-1.55]; P < .001). Readmission within 30 days was less common after admission to community compared with VHA hospitals (4898 of 38 576 [12.7%] vs 2006 of 14 357 [14.0%]; risk-adjusted hazard ratio, 0.89 [95% CI, 0.86-0.92]; P < .001). Conclusions and Relevance: This study found that most hospitalizations for COVID-19 among VHA enrollees aged 65 years or older were in community hospitals and that veterans experienced higher mortality in community hospitals than in VHA hospitals. The VHA must understand the sources of the mortality difference to plan care for VHA enrollees during future COVID-19 surges and the next pandemic.

Effect of Chronic Disease Home Telehealth Monitoring in the Veterans Health Administration on Healthcare Utilization and Mortality.

BACKGROUND: The high prevalence of chronic diseases, including congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), and diabetes mellitus (DM), accounts for a large burden of cost and poor health outcomes in US hospitals, and home telehealth (HT) monitoring has been proposed to improve outcomes. OBJECTIVE: To measure the association between HT initiation and 12-month inpatient hospitalizations, emergency department (ED) visits, and mortality in veterans with CHF, COPD, or DM. DESIGN: Comparative effectiveness matched cohort study. PATIENTS: Veterans aged 65 years and older treated for CHF, COPD, or DM. MAIN MEASURES: We matched veterans initiating HT with veterans with similar demographics who did not use HT (1:3). Our outcome measures included a 12-month risk of inpatient hospitalization, ED visits, and all-cause mortality. KEY RESULTS: A total of 139,790 veterans with CHF, 65,966 with COPD, and 192,633 with DM were included in this study. In the year after HT initiation, the risk of hospitalization was not different in those with CHF (adjusted odds ratio [aOR] 1.01, 95% confidence interval [95%CI] 0.98-1.05) or DM (aOR 1.00, 95%CI 0.97-1.03), but it was higher in those with COPD (aOR 1.15, 95%CI 1.09-1.21). The risk of ED visits was higher among HT users with CHF (aOR 1.09, 95%CI 1.05-1.13), COPD (1.24, 95%CI 1.18-1.31), and DM (aOR 1.03, 95%CI 1.00-1.06). All-cause 12-month mortality was lower in those initiating HT monitoring with CHF (aOR 0.70, 95%CI 0.67-0.73) and DM (aOR 0.79, 95%CI 0.75-0.83), but higher in COPD (aOR 1.08, 95%CI 1.00-1.16). CONCLUSIONS: The initiation of HT was associated with increased ED visits, no change in hospitalizations, and lower all-cause mortality in patients with CHF or DM, while those with COPD had both higher healthcare utilization and all-cause mortality.

Relationships Between Pediatric Safety Indicators Across a National Sample of Pediatric Hospitals: Dispelling the Myth of the "Safest" Hospital.

OBJECTIVE: There are many measures of healthcare quality, but no obvious summary measures to simplify ranking of hospital performance. With public reporting and accountability for hospital performance, the validity of composite measures for performance rankings has increased importance. This study aimed to explore the covariance of pediatric hospital quality indicators and evaluate the use of a single composite score. METHODS: We performed an observational study of pediatric hospital performance across 13 safety indicators extracted from the Pediatric Health Information System, a comparative database of children's hospitals in the United States. We included patients discharged from 36 hospitals from January 1, 2016, to December 31, 2019. Using principal components analysis, we investigate relationships among patient safety measures from the Agency for Healthcare Research and Quality pediatric quality indicators and Center for Medicare and Medicaid Services hospital-acquired conditions. We compare and summarize rankings based on individual safety indicators and calculate alternative composite scores. RESULTS: We identified 5 orthogonal variance components accounting for 68% of variation in pediatric hospital quality indicators. Rankings demonstrated greater within-hospital variation compared with between-hospital variation. We observed discordant rankings across commonly used summary measures and conclude that these pediatric safety measures demonstrate at least 2 underlying variance components. CONCLUSIONS: This study demonstrates the multifactorial nature of patient safety. This implies no unique ordering of hospitals based on these measures, and thus, no pediatric hospital can claim to be "the safest." This raises further questions about appropriate methods to rank hospitals by safety.

Perception of Affordances in Soccer: Kicking for Power Versus Kicking for Precision.

Purpose: We investigated youth soccer players' perception of affordances for different types of kicks. Method: In the Power task, players judged the maximum distance they could kick the ball. In the Precision task, players judged how close to a designated target line they could kick the ball. Following judgments, players performed each task. Both judgments and performance were assessed immediately before and immediately after players competed in a regulation soccer match, thereby permitting us to assess possible effects of long-term experience on perceptual sensitivity to short-term changes in ability. We compared players from two league groups: U16 (mean age = 15.45 years, SD = 0.52 years) versus U18 (mean age = 17.55 years, SD = 0.52 years). Results: As expected, for the Power task actual kicking ability was greater for the U18 group (p < .05). In statistically significant interactions, we found that judgments of Power kicking ability differed before versus after match play, but only for the U16 group. We found no statistically significant effects for the Precision task. Conclusions: We identified interactions between long-term and short-term soccer experience which revealed that the effects of long-term experience on affordance perception were not general. Two additional years of playing experience (in the U18 group, relative to the U16 group) did not lead to an overall improvement in the perception of kicking-related affordances. Rather, variation in long-term experience was associated with changes in affordance perception which were situation-specific, being manifested only after playing a soccer match, and not before.

Implementing a Telehospitalist Program Between Veterans Health Administration Hospitals: Outcomes, Acceptance, and Barriers to Implementation.

BACKGROUND: Telehospitalist services are an innovative alternative approach to address staffing issues in rural and small hospitals. OBJECTIVE: To determine clinical outcomes and staff and patient satisfaction with a novel telehospitalist program among Veterans Health Administration (VHA) hospitals. DESIGN, SETTING, AND PARTICIPANTS: We conducted a mixed-methods evaluation of a quality improvement program with pre- and postimplementation measures. The hub site was a tertiary (high-complexity) VHA hospital, and the spoke site was a 10-bed inpatient medical unit at a rural (low-complexity) VHA hospital. All patients admitted during the study period were assigned to the spoke site. INTERVENTION: Real-time videoconferencing was used to connect a remote hospitalist physician with an on-site advanced practice provider and patients. Encounters were documented in the electronic health record. MAIN OUTCOMES: Process measures included workload, patient encounters, and daily census. Outcome measures included length of stay (LOS), readmission rate, mortality, and satisfaction of providers, staff, and patients. Surveys measured satisfaction. Qualitative analysis included unstructured and semi-structured interviews with spoke-site staff. RESULTS: Telehospitalist program implementation led to a significant reduction in LOS (3.0 [SD, 0.7] days vs 2.3 [SD, 0.3] days). The readmission rate was slightly higher in the telehospitalist group, with no change in mortality rate. Satisfaction among teleproviders was very high. Hub staff perceived the service as valuable, though satisfaction with the program was mixed. Technology and communication challenges were identified, but patient satisfaction remained mostly unchanged. CONCLUSION: Telehospitalist programs are a feasible and safe way to provide inpatient coverage and address rural hospital staffing needs. Ensuring adequate technological quality and addressing staff concerns in a timely manner can enhance program performance.

Development and implementation of a Telenephrology dashboard for active surveillance of kidney disease: a quality improvement project.

BACKGROUND: Kidney disease accounts for more than 49 billion dollars in healthcare expenditures annually. Early detection and intervention may reduce the burden of disease. We describe a quality improvement project to develop a telenephrology dashboard that proactively monitors kidney disease. METHODS: One hundred eighty-four thousands Veterans within the Iowa City Veterans Affairs Health Care System were eligible for telenephrology consultation. The dashboard accessed the charts of 53,085 Veterans at risk for kidney disease. We utilized Lean-Six Sigma tools and principles and the Define-Measure-Analyze-Improve-Control Framework to develop and deploy a telenephrology dashboard in 4 community-based outpatient clinics (CBOCs). The primary measure was the number of days to complete consultation. Secondary measures included number of electronic consultations per month, distance and cost of Veteran travel saved, and number of steps for completion of consult. RESULTS: The data of 1384 Veterans at the 4 CBOCs were analyzed by the telenephrology dashboard, of which 459 generated telenephrology consults. The number of days to complete any type of consultation was unchanged (48.9 days in 2019, compared to 41.6 days in 2017). The average Veteran saved between $21.60 to $63.90 per trip to Iowa City. Between March 2019 and August 2019, there were 27.3 telenephrology consults per month. The number of steps needed to complete the consult request was decreased from 13 to 9. CONCLUSIONS: Utilization of the telenephrology dashboard system contributed to an increase in consultations completed through electronic means without decreasing face-to-face consults. Electronic consults now outnumber traditional face-to-face consultations at our institution. Telenephrology consultation improved early detection and identification of kidney disease and saved time and costs for Veterans in travel, but did not decrease the average number of days to complete consultation requests.

Applying a Text-Search Algorithm to Radiology Reports Can Find More Patients With Pulmonary Nodules Than Radiology Coding Alone.

INTRODUCTION: Chest imaging often incidentally finds indeterminate nodules that need to be monitored to ensure early detection of lung cancers. Health care systems need effective approaches for identifying these lung nodules. We compared the diagnostic performance of 2 approaches for identifying patients with lung nodules on imaging studies (chest/abdomen): (1) relying on radiologists to code imaging studies with lung nodules; and (2) applying a text search algorithm to identify references to lung nodules in radiology reports. METHODS: We assessed all radiology studies performed between January 1, 2016 and November 30, 2016 in a single Veterans Health Administration hospital. We first identified imaging reports with a diagnostic code for a pulmonary nodule. We then applied a text search algorithm to identify imaging reports with key words associated with lung nodules. We reviewed medical records for all patients with a suspicious radiology report based on either search strategy to confirm the presence of a lung nodule. We calculated the yield and the positive predictive value (PPV) of each search strategy for finding pulmonary nodules. RESULTS: We identified 12,983 imaging studies with a potential lung nodule. Chart review confirmed 8,516 imaging studies with lung nodules, representing 2,912 unique patients. The text search algorithm identified all the patients with lung nodules identified by the radiology coding (n = 1,251) as well as an additional 1,661 patients. The PPV of the text search was 72% (2,912/4,071) and the PPV of the radiology code was 92% (1,251/1,363). Among the patients with nodules missed by radiology coding but identified by the text search algorithm, 130 had lung nodules > 8 mm in diameter. CONCLUSIONS: The text search algorithm can identify additional patients with lung nodules compared to the radiology coding; however, this strategy requires substantial clinical review time to confirm nodules. Health care systems adopting nodule-tracking approaches should recognize that relying only on radiology coding might miss clinically important nodules.

Service Evaluation of Methoxyflurane Versus Standard Care for Overall Management of Patients with Pain Due to Injury.

INTRODUCTION: Inhaled methoxyflurane is an analgesic used for the emergency relief of moderate to severe pain in conscious adult patients with trauma and associated pain that is increasingly being used in hospital emergency departments to provide rapid analgesia. It is widely accepted that effective pain relief can facilitate patient care and flow through the emergency department (ED). The main aim of this evaluation was to assess the impact of inhaled methoxyflurane on patient length of stay (LOS) in the ED compared with standard care. METHODS: Adult patients with moderate to severe trauma pain and Glasgow coma score of 15 were included in the evaluation. Evaluation forms were completed for 79 patients who received methoxyflurane and were matched with 80 patients who received standard care. RESULTS: Overall the mean time spent in the ED was reduced by 71 min in those patients who were administered methoxyflurane compared with patients who received standard care. Furthermore, analysis of LOS by injury type demonstrated a reduction in ED LOS by 183 min for patients with shoulder dislocation who were treated with methoxyflurane compared with patients who received standard care. There was no reduction in ED LOS for patients with lower limb, hip or pelvic injuries between the two treatment groups. CONCLUSION: Use of methoxyflurane in adult patients with trauma pain significantly reduced the ED LOS and may potentially improve patient flow through the ED.

Bridging in vitro dissolution and in vivo exposure for acalabrutinib. Part II. A mechanistic PBPK model for IR formulation comparison, proton pump inhibitor drug interactions, and administration with acidic juices.

Acalabrutinib (Calquence®) 100 mg (bid) has received accelerated approval by FDA for the treatment of adult patients with mantle cell lymphoma (MCL) who have received at least one prior therapy. Acalabrutinib is a substrate of PgP and CYP3A4, with a significant fraction of drug metabolized by first pass gut extraction and 25% absolute bioavailability. The absorption of acalabrutinib is affected by stomach pH, with lower pharmacokinetic exposure observed following co-administration with proton pump inhibitors. During dissolution at pH values below its highest basic pKa, the two basic moieties of acalabrutinib react with protons from the aqueous solution, leading to a higher pH at the drug surface than in the bulk solution. A batch-specific product particle size distribution (P-PSD), was derived from dissolution data using a mechanistic model that was based on the understanding of surface pH and the contribution of micelles to the dissolution rate. P-PSD values obtained for various batches of acalabrutinib products in simple buffers, or in complex fluids such as fruit juices, were successfully integrated into a physiologically based pharmacokinetic (PBPK) model developed using GastroPlus v9.0™. The integrated model allowed the prediction of clinical pharmacokinetics under normal physiological stomach pH conditions as well as following treatment with proton pump inhibitors. The model also accounted for lower pharmacokinetic exposure that was observed when acalabrutinib was co-administered with the acidic beverages, grapefruit juice, (which contains CYP3A inhibitors), and orange drink (which does not contain CYP3A inhibitors), relative to administration with water. The integration of dissolution data in the PBPK model enables mechanistic understanding and the establishment of more robust in vitro-in vivo correlations (IVIVC) under a variety of conditions. The model can then distinguish the interplay between dissolution and first pass extraction and how in vivo stomach pH, saturation of gut PgP, and saturation or inhibition of gut CYP3A4, will impact the pharmacokinetics of acalabrutinib.

Impact of time from biopsy to surgery on complications, functional and oncologic outcomes following radical prostatectomy

ABSTRACT Introduction: To determine the impact of time from biopsy to surgery on outcomes following radical prostatectomy (RP) as the optimal interval between prostate biopsy and RP is unknown. Material and methods: We identified 7, 350 men who underwent RP at our institution between 1994 and 2012 and had a prostate biopsy within one year of surgery. Patients were grouped into five time intervals for analysis: ≤ 3 weeks, 4-6 weeks, 7-12 weeks, 12-26 weeks, and > 26 weeks. Oncologic outcomes were stratified by NCCN disease risk for comparison. The associations of time interval with clinicopathologic features and survival were evaluated using multivariate logistic and Cox regression analyses. Results: Median time from biopsy to surgery was 61 days (IQR 37, 84). Median follow-up after RP was 7.1 years (IQR 4.2, 11.7) while the overall perioperative complication rate was 19.7% (1,448/7,350). Adjusting for pre-operative variables, men waiting 12-26 weeks until RP had the highest likelihood of nerve sparing (OR: 1.45, p = 0.02) while those in the 4-6 week group had higher overall complications (OR: 1.33, p = 0.01). High risk men waiting more than 6 months had higher rates of biochemical recurrence (HR: 3.38, p = 0.05). Limitations include the retrospective design. Conclusions: Surgery in the 4-6 week time period after biopsy is associated with higher complications. There appears to be increased biochemical recurrence rates in delaying RP after biopsy, for men with both low and high risk disease.

Perioperative outcomes of robot-assisted laparoscopic partial cystectomy.

Reports of surgical outcomes after robotic partial cystectomy are limited. The objective of this study is to review surgical outcomes after robotic partial cystectomy at a large tertiary referral center and compare outcomes with patients undergoing open partial cystectomy. Patients undergoing robotic partial cystectomy between 2003 and 2014 were identified. Patients were matched 2:1 based on gender, age, and Charlson Comorbidity Score with patients undergoing open partial cystectomy during the same time period. Patient charts were reviewed for surgical outcomes. Conditional logistic regression adjusted for matching was used to compare outcomes. At our institution, 11 patients underwent robotic partial cystectomy between 2003 and 2014. Median operative time was significantly longer in the robotic group, 214 (IQR 93, 230) minutes, than the open group, 93 (IQR 58, 143) minutes (p = 0.01). There was no difference in median estimated blood loss (p = 0.1). No patient required transfusion. There were no intraoperative complications. Median hospital stay was significantly shorter in the robotic partial cystectomy group, 1 (IQR 1, 2) day, than the open partial cystectomy group, 2 (IQR 2, 4) days (p = 0.01). Median duration of catheterization and complications within 30 days of surgery were not statistically different between the two groups. Median follow-up was 15.5 (IQR 8.6, 19.7) months for the robotic partial cystectomy group and 40.7 (IQR 6.5, 69.4) months for the open partial cystectomy group. Robotic partial cystectomy is safe, effective, and is associated with minimal morbidity when performed in properly selected patients for benign and malignant indications. When compared with open partial cystectomy, robotic partial cystectomy is associated with a longer operative time, but results in a shorter postoperative hospital stay.

Surgical patient selection and counseling.

The objectives of patient selection and counseling are ultimately to enhance successful outcomes. However, the definition for success is often narrowly defined in published literature (ability to complete surgery, complications, satisfaction) and fails to account for patient desires and expectations, temporal changes, natural history of underlying diseases, or independent validation. Factors associated with satisfaction and dissatisfaction are often surgery-specific, although correlation with pre-operative expectations, revisions, and complications are common with most procedures. The process of appropriate patient selection is determined by the integration of patient and surgeon factors, including psychological capacity to handle unsatisfactory results, baseline expectations, complexity of case, and surgeon volume and experience. Using this model, a high-risk scenario includes one in which a low-volume surgeon performs a complex case in a patient with limited psychological capacity and high expectations. In contrast, a high-volume surgeon performing a routine case in a male with low expectations and abundant psychiatric reserve is more likely to achieve a successful outcome. To further help identify patients who are at high risk for dissatisfaction, a previously published mnemonic is recommended: CURSED Patient (compulsive/obsessive, unrealistic, revision, surgeon shopping, entitled, denial, and psychiatric). Appropriate patient counseling includes setting appropriate expectations, reviewing the potential and anticipated risks of surgery, post-operative instruction to limit complications, and long-term follow-up. As thorough counseling is often a time-consuming endeavor, busy practices may elect to utilize various resources including educational materials, advanced practice providers, or group visits, among others. The consequences for poor patient selection and counseling may range from poor surgical outcomes and patient dissatisfaction to lawsuits, loss of credibility, or even significant patient or personal harm.

Analytical confirmation of synthetic cannabinoids in a cohort of 179 presentations with acute recreational drug toxicity to an Emergency Department in London, UK in the first half of 2015.

CONTEXT: Synthetic cannabinoid receptor agonists are the largest group of new psychoactive substances reported in the last decade; in this study we investigated how commonly these drugs are found in patients presenting to the Emergency Department with acute recreational drug toxicity. METHODS: We conducted an observational cohort study enrolling consecutive adult patients presenting to an Emergency Department (ED) in London (UK) January-July 2015 (6 months) with acute recreational drug toxicity. Residual serum obtained from a serum sample taken as part of routine clinical care was analyzed using high-resolution accurate mass-spectrometry with liquid-chromatography (HRAM-LCMSMS). Minimum clinical data were obtained from ED medical records. RESULTS: 18 (10%) of the 179 patient samples were positive for synthetic cannabinoid receptor agonists. The most common was 5F AKB-48 (13 samples, concentration 50-7600 pg/ml), followed by 5F PB-22 (7, 30-400 pg/mL), MDMB-CHMICA (7, 80-8000 pg/mL), AB-CHMINACA (3, 50-1800 pg/mL), Cumyl 5F-PINACA (1, 800 pg/mL) and BB-22 (1, 60 pg/mL). Only 9/18 (50%) in whom synthetic cannabinoid receptor agonists were detected self-reported synthetic cannabinoid receptor agonist use. The most common clinical features were seizures and agitation, both recorded in four (22%) individuals. Fourteen patients (78%) were discharged from the ED, one of the four admitted to hospital was admitted to critical care. CONCLUSIONS: Synthetic cannabinoid receptor agonists were found in 10% of this cohort with acute recreational drug toxicity but self-reported in only half of these. This suggests that presentations to the ED with acute synthetic cannabinoid receptor agonist toxicity may be more common than reported.

Renal fossa recurrence after nephrectomy for renal cell carcinoma: prognostic features and oncological outcomes.

OBJECTIVES: To describe the clinicopathological features associated with increased risk of renal fossa recurrence (RFR) after radical nephrectomy (RN) and to describe the prognostic features associated with cancer-specific survival (CSS) among patients with RFR treated with primary locally directed therapy, systemically directed therapy or expectant management. PATIENTS AND METHODS: The records of 2 502 patients treated with RN for unilateral, sporadic, localized renal cell carcinoma (RCC) between 1970 and 2006 were reviewed. CSS after RFR was estimated using the Kaplan-Meier method. Associations with the development of RFR and CSS after RFR were evaluated using Cox proportional hazards regression models. RESULTS: A total of 33 (1.3%) patients developed isolated RFR (iRFR) and 30 (1.2%) patients developed RFR in the setting of synchronous metastases after RN (study cohort, N = 63). The median follow-up for the series was 9.0 years after RN and 6.0 years after RFR diagnosis. On multivariable analysis, advanced pathological stage (pT2: hazard ratio [HR] 4.36, P = 0.004; pT3/4: HR 4.39, P = 0.003) and coagulative necrosis (HR 2.71, P = 0.006) were independently associated with increased risk of iRFR. The median time to recurrence was 1.5 years after RN among the 33 patients with iRFR, and 1.4 years among all patients. Overall, the median CSS was 2.5 years after diagnosis of iRFR, 1.3 years after RFR in the setting of synchronous metastases, and 2.2 years overall. After primary locally directed therapy (surgery, ablation or radiation), systemic therapy or expectant management, the 3-year CSS rates among patients with iRFR were 63%, 50% and 13% (P = 0.001) and were 64%, 50% and 28% (P = 0.006) among all patients, respectively. On multivariable analysis, when compared with observation, locally directed therapies were associated with a significantly decreased risk of death from RCC (HR 0.26, P < 0.001). CONCLUSIONS: Renal fossa recurrence is a rare event after RN for RCC and portends a poor prognosis, even in the absence of synchronous metastases. Development of iRFR is associated with advanced stage and aggressive tumour biology. Patients who underwent primary locally directed therapy had superior CSS compared with those treated with expectant management, supporting the use of aggressive local treatment in carefully selected patients with RFR. Future research is needed to determine the optimum role and sequencing of combined therapy in patients with this rare entity.

An assessment of the variation in the concentration of acetylcysteine in infusions for the treatment of paracetamol overdose.

BACKGROUND: Intravenous acetylcysteine is the treatment of choice for paracetamol poisoning. A previous UK study in 2001 found that 39% of measured acetylcysteine infusion concentrations differed by >20% from anticipated concentrations. In 2012, the UK Commission on Human Medicines made recommendations for the management of paracetamol overdose, including provision of weight-based acetylcysteine dosing tables. The aim of this study was to assess variation in acetylcysteine concentrations in administered infusions following the introduction of this guidance. METHODS: A 6-month single-centre prospective study was undertaken at a UK teaching hospital. After preparation, 5-ml samples were taken from the first, second and third/any subsequent acetylcysteine infusions. Acetylcysteine was measured in diluted (1:50) samples by high-performance liquid chromatography. Comparisons between measured and expected concentrations based on prescribed weight-based dose and volume were made for each infusion. RESULTS: Ninety samples were collected. There was a variation of ≤10% in measured compared to expected concentration for 45 (50%) infusions, of 10-20% for 27 (30%) infusions, 20.1-50% for 14 (16%) infusions and >50% for four (4%) infusions. There was a median (interquartile range) variation in measured compared to expected concentration of -3.6 mg ml-1 (-6.7 to -2.3) for the first infusion, +0.2 mg ml-1 (-0.9 to +0.4) for the second infusion and -0.3 mg ml-1 (-0.6 to +0.2) for third and fourth infusions. CONCLUSION: There has been a moderate improvement in the variation in acetylcysteine dose administered by infusion. Further work is required to understand the continuing variation and consideration should be given to simplification of acetylcysteine regimes to decrease the risk of administration errors.

Urinary collecting system invasion is associated with poor survival in patients with clear-cell renal cell carcinoma.

OBJECTIVES: To evaluate the prognostic significance of urinary collecting system invasion (UCSI) in a large series of patients with clear-cell renal cell carcinoma (RCC). MATERIALS AND METHODS: Patients with clear-cell RCC treated with nephrectomy between 2001 and 2010 were reviewed from a prospectively maintained registry. One urological pathologist re-reviewed all slides. Cancer-specific survival was estimated using the Kaplan-Meier method, and associations of UCSI with death from RCC were evaluated using Cox models. RESULTS: Of the 859 patients with clear-cell RCC, 58 (6.8%) had UCSI. At last follow-up, 310 patients had died from RCC at a median of 1.8 years after surgery. The median follow-up for patients alive at last follow-up was 8.2 years. The estimated cancer-specific survival at 10 years after surgery for patients with UCSI was 17%, compared with 60% for patients without UCSI (P < 0.001). In a multivariable model, UCSI remained independently associated with an increased risk of death from RCC (hazard ratio 1.5; P = 0.018). Further, among patients with pT3 RCC, those with USCI had survival outcomes similar to those of patients with pT4 RCC. CONCLUSIONS: Collecting system invasion is associated with poor prognosis among patients with clear-cell RCC. If validated, consideration should be given to including UCSI in future staging systems.
