RESUMEN

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.

RESUMEN

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.

RESUMEN

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 followup 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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

PURPOSE: Medical expulsive therapy represents an effective adjunctive treatment for nonpregnant patients with symptomatic urolithiasis. Tamsulosin is classified by the FDA (Food and Drug Administration) as a category B medication. However, to our knowledge no published data exist for human pregnancy. We explored the safety and efficacy of tamsulosin therapy for symptomatic urolithiasis occurring during pregnancy. MATERIALS AND METHODS: We retrospectively identified patients treated with tamsulosin for stone disease during pregnancy at the Mayo Clinic during 2000 to 2014. This medical expulsive therapy cohort was matched 2:1 to pregnant women with symptomatic urolithiasis during pregnancy who did not receive medical expulsive therapy. Groups were compared using linear mixed models for continuous variables and exact conditional logistic regression models for nominal variables to take into account correlation due to matching. RESULTS: A total of 27 patients receiving medical expulsive therapy comprised the study cohort. Median duration of antepartum tamsulosin exposure was 3 days (range 1 to 110), occurring during the first, second and third trimester in 3 (11%), 11 (40.7%) and 18 (67%) patients, respectively. Mean gestational age at delivery was 38.1 weeks (SD 2.4) and 6 (22%) infants were born preterm. All infant birthweights were considered appropriate for gestational age, and no cases of spontaneous abortion, intrauterine demise or neonatal congenital anomalies were encountered. Comparison between the medical expulsive therapy and control groups demonstrated no significant differences in maternal or infant outcomes for any of the examined variables. CONCLUSIONS: Tamsulosin medical expulsive therapy does not appear to be associated with adverse maternal or fetal outcomes and may be considered as adjunctive therapy for urolithiasis during pregnancy.

RESUMEN

PURPOSE: To our knowledge there are no guidelines for the evaluation and management of incontinence in women with an orthotopic neobladder. We propose a treatment algorithm based on our experience with treating this patient population. MATERIALS AND METHODS: We identified women in whom orthotopic neobladder diversion and surgery for incontinence were performed from January 1, 1995 to January 1, 2014. Charts were reviewed for management, outcomes and complications within 30 days of surgery. RESULTS: At this institution 12 women with orthotopic neobladder diversion were treated with surgery for incontinence between 1995 and 2014. Six women (50%) had an undiagnosed neovesicovaginal fistula, of whom 3 (50%) underwent successful fistula repair. A total of 12 bulking agent injections were performed in 6 women (50%). The outcomes were continued dryness after 1 injection (8%), transient improvement after 9 (75%), immediate failure after 1 (8%) and secondary fistula development after 1 (8%). Four transobturator slings and 4 pubovaginal slings were placed in a total of 6 patients (50%), of whom 1 (17%) was dry and 1 (17%) was improved. At a median followup of 22.9 months (IQR 11.1-46.4) 6 women (50%) were dry or improved and 6 (50%) had no improvement in leakage. Of the 6 (50%) women who were dry or improved 2 (17%) achieved planned intermittent catheterization after surgery and 2 (17%) underwent ileal conduit conversion. CONCLUSIONS: Bulking agents have low long-term efficacy and carry the risk of fistula formation. The efficacy of tension-free sling placement is low and continence requires an obstructing sling. Counseling should include acceptance of multiple procedures, which may be necessary to achieve continence, and consideration of conduit diversion.

RESUMEN

PURPOSE: Collagenase clostridium histolyticum is approved for the treatment of Peyronie's disease. To date, no post-release study to our knowledge has evaluated patient perceived outcomes and satisfaction. Therefore, we evaluated patient perceived experience with collagenase clostridium histolyticum injection for Peyronie's disease in a clinical practice. MATERIALS AND METHODS: From March 2014 to July 2015, 69 patients underwent 1 to 4 series of collagenase clostridium histolyticum injections for Peyronie's disease at our institution. Objective changes in penile curvature as well as patient reported functional outcomes and patient perceived curvature improvements were evaluated. RESULTS: By the time of analysis 31 patients (45%) had completed 4 trials, 47 (68%) completed 3 trials and 59 (86%) completed 2 trials. Patient reported improvements (percentage) in curvature increased with each series (trial 1-14%, trial 2-28%, trial 3-30% and trial 4-37%, p <0.05). Among those completing therapy 57% reported that collagenase clostridium histolyticum injections negated a need for surgery and 52% reported restoration of penetration. Overall 81% of men perceived collagenase clostridium histolyticum treatment as meaningful and 88% reported subjective improvements after 4 series of injections. Objective measures demonstrated a mean 23-degree curvature improvement (38%, p <0.0001). Seven patients (10%) experienced penile hematomas and no patients experienced tunical rupture. CONCLUSIONS: Collagenase clostridium histolyticum reduced the need for surgery and restored penetration in the majority of patients completing 4 series of injections. It also significantly reduced the degree of objectively measured penile curvature. Subjective improvements in curvature increased with each series of collagenase clostridium histolyticum injections as well and the majority of patients considered the therapy worthwhile.

RESUMEN

BACKGROUND: The licensed intravenous acetylcysteine regimen for treating paracetamol overdose in most countries uses three separate infusions over 21 h. This complex regimen, requiring different infusion concentrations and rates, has been associated with administration errors. The aim of the present study was to assess the extent of administration delays occurring during this acetylcysteine regimen. METHOD: A 6-month retrospective observational study was conducted at three English teaching hospitals with clinical toxicology services from October 2014. Patients aged 16 years and over, treated with intravenous acetylcysteine for paracetamol overdose, were included. The start times for infusions were recorded and the delays compared with the prescribed infusion times were calculated. Anaphylactoid reactions, intravenous cannula problems, overdose intent and smoking status were recorded to assess their contribution to delays. RESULTS: From 263 cases identified, 198 met the study inclusion criteria. The median time between the start of infusions 1 and 3 was delayed from the intended 5 h by a median (interquartile range) of 90 (50-163) min, with 135 (68%) cases delayed by more than 1 h. Significantly longer delays were observed in patients with anaphylactoid reactions [median delay 267 (217-413) min, n = 8] and accidental/supratherapeutic overdose [median delay 170 (95-260) min, n = 29]. There were no significant differences between smokers and nonsmokers, or for patients with intravenous cannula problems. CONCLUSION: Long delays were identified during the three-infusion acetylcysteine regimen for the treatment of paracetamol overdose. These were of clinical significance and could lead to periods of subtherapeutic plasma acetylcysteine concentrations and potentially avoidable hepatotoxicity, as well as delaying hospital discharge.

RESUMEN

PURPOSE: Ethylphenidate is a novel psychoactive substance that is an analogue of methylphenidate. This paper describes its availability, patterns of use, and acute effects. METHODS: Searches of the scientific and grey literature (publicly accessible Internet resources) were undertaken, using the keywords "Ethylphenidate", "Ethyl phenidate", "Ethyl phenyl(piperidin-2-yl)acetate", and "Nopaine", to identify information on the prevalence and patterns of use, desired effects, and toxicity of ethylphenidate. An Internet snapshot survey was performed on 10 February 2015 to provide information on availability and cost of ethylphenidate. RESULTS: The literature search identified 1 case series of acute recreational ethylphenidate toxicity, 1 case report of ethylphenidate dependence, 1 qualitative analysis of user reports on Internet drug forums, 2 conference abstracts for surveillance studies, 1 report of two cases of ethylphenidate detected in post-mortem analyses, and 198 user reports on Internet discussion forums and social media sites. The Internet snapshot survey found 83 websites selling ethylphenidate, with purchase prices ranging from £28.20 ± 0.63 (€37.71 ± 0.85) per gram for a 500-mg amount to £2.64 ± 0.57 (€3.53 ± 0.77) per gram for 1 kg. The published cases and Internet user reports suggest the acute effects of ethylphenidate are similar to other stimulant drugs; the most common route of use was by nasal insufflation. The most common desired effects were euphoria, stimulation, and increased concentration, sociability, and energy levels; the most common unwanted effects included anxiety, palpitations, insomnia, and paranoia. CONCLUSION: This review of the scientific and grey literature has demonstrated that the acute harms associated with its use are stimulant in nature and that ethylphenidate is widely available to users over the Internet, with significant discounts for bulk purchases.

RESUMEN

BACKGROUND: Veterans Health Administration (VHA) enrollees may use community hospitals for inpatient care and sometimes require transfer to larger community or VHA hospitals. Little is known about interhospital transfer patterns among veterans using community and VHA hospitals or how coronavirus disease 2019 (COVID-19) case surges affected transfer. METHODS: Retrospective cohort study among veterans age 65+ admitted to community and VHA hospitals for acute myocardial infarction (AMI) or acute ischemic stroke (AIS) during 2018-2021. We examined associations between COVID-19 case density in regional hospital referral networks and the likelihood of transfer. RESULTS: A total of 8373 (23.6%) veterans with AMI and 4630 (13.1%) with AIS were transferred in the prepandemic period. Transfer was especially common for rural veterans (36% with AMI, 20% with AIS). Most transfers (88%) were between community hospitals and 6% from community to VHA. Among AMI patients, transfer was less likely among patients age >90 (relative to age 65-69), those with non-White race/ethnicity, and females. Transfer was more common among patients initially seen in rural hospitals (AMI, odds ratio [OR] = 2.73, 95% confidence interval [CI], 2.90-3.74; AIS, OR = 2.43; 95% CI, 2.24-2.65). During 2020-2021, transfer among AMI patients was less likely during COVID-19 case density surges affecting the admitting hospital's referral network (OR = 0.86; 95% CI, 0.78-0.96 for highest compared with lowest quartile of COVID-19 cases). CONCLUSION: Interhospital transfer was common for veterans with AMI and AIS, especially among rural veterans. Few transfers were to VHA hospitals. COVID-19 case surges were associated with decreased transfer for veterans with AMI, potentially limiting access to needed care.

RESUMEN

While numerous studies have assessed the outcomes of methicillin-resistant S. aureus (MRSA) colonization over the short term, little is known about longer-term outcomes after discharge. An assessment of long-term outcomes could provide information about the utility of various MRSA prevention approaches. A matched-cohort study was performed among Veterans Affairs (VA) patients screened for MRSA colonization between the years 2007 and 2009 and followed to evaluate outcomes until 2010. Cox proportional-hazard models were used to evaluate the association between MRSA colonization and long-term outcomes, such as infection-related readmission and crude mortality. A total of 404 veterans were included, 206 of whom were MRSA carriers and 198 of whom were noncarriers. There were no culture-proven MRSA infections on readmission among the noncarriers, but 13% of MRSA carriers were readmitted with culture-proven MRSA infections on readmission (P < 0.01). MRSA carriers were significantly more likely to be readmitted, to be readmitted more than once due to proven or probable MRSA infections, and to be readmitted within 90 days of discharge than noncarriers (P < 0.05). Infection-related readmission (adjusted hazard ratio [HR] = 4.07; 95% confidence interval [CI], 2.16 to 7.67) and mortality (adjusted HR = 2.71; 95% CI, 1.87 to 3.91) were significantly higher among MRSA carriers than among noncarriers after statistically adjusting for potential confounders. Among a cohort of VA patients, MRSA carriers are at high risk of infection-related readmission, MRSA infection, and mortality compared to noncarriers. Noncarriers are at very low risk of subsequent MRSA infection. Future studies should address whether interventions such as nasal or skin decolonization could result in improved outcomes for MRSA carriers.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.
