Molecular Biomarker and Programmed Death-Ligand 1 Expression Testing in Patients With Advanced Stage Non-small Cell Lung Cancer Across North Carolina Community Hospitals.

BACKGROUND: Precision medicine in advanced non-small cell lung cancer (NSCLC) requires molecular biomarker testing in patients with nonsquamous and select patients with squamous histologies, and programmed death-ligand 1 (PD-L1) testing in both. RESEARCH QUESTION: What are rates of molecular and PD-L1 biomarker testing in patients with advanced NSCLC in community practices, and do rates vary by sociodemographic factors? What is the prevalence of molecular biomarker mutations and PD-L1 expression levels? STUDY DESIGN AND METHODS: From 389 stage IV NSCLC pathology reports obtained through the University of North Carolina Lineberger Comprehensive Cancer Center's Rapid Case Ascertainment Program from 38 community hospitals across North Carolina, we abstracted demographics, histology, molecular biomarker testing and results, and PD-L1 testing and expression. We geocoded patient and hospital addresses to determine travel time, distance to care, and census block level contextual variables. We compared molecular biomarker and PD-L1 testing rates, the prevalence of molecular biomarkers, and PD-L1 expression levels by race and sex, using χ2 tests. We determined predictors of testing, using multivariable logistic regression and report adjusted ORs and 95%CI. RESULTS: Among patients with nonsquamous NSCLC, 64.4% were tested for molecular biomarkers, and among all NSCLC patients 53.2% were tested for PD-L1 expression. Differences in biomarker testing rates by sociodemographic factors were not statistically significant in univariate or adjusted analyses. Adjusted analyses showed that patients living in areas with higher household internet access were more likely to undergo PD-L1 testing (adjusted OR = 1.66, 95% CI, 1.02-2.71). Sociodemographic differences in molecular biomarker prevalence and PD-L1 expression levels were not statistically significant, except for human epidermal growth factor receptor 2 (HER2) mutations, which occurred in 16.7% of males vs 0% in females, P = .05. INTERPRETATION: Biomarker testing remains underused in NSCLC. Future work should include larger populations and evaluate hospital-specific testing protocols to identify and address barriers to guideline-recommended testing.

Impact of COVID-19 on utilization of nonpharmacological and pharmacological treatments for chronic low back pain and clinical outcomes.

CONTEXT: The novel coronavirus 2019 (COVID-19) pandemic has impacted the delivery of health care services throughout the United States, including those for patients with chronic pain. OBJECTIVES: To measure changes in patients' utilization of nonpharmacological and pharmacological treatments for chronic low back pain and related outcomes during the COVID-19 pandemic. METHODS: A pre-post study was conducted within the Pain Registry for Epidemiological, Clinical, and Interventional Studies and Innovation (PRECISION Pain Research Registry) using data in the 3 months before and 3-6 months after the declaration of a national emergency related to COVID-19. Participants 21-79 years old with chronic low back pain were included in the study and provided self reported data at relevant quarterly encounters. Use of exercise therapy, yoga, massage therapy, spinal manipulation, acupuncture, cognitive behavioral therapy, nonsteroidal antiinflammatory drugs, and opioids for low back pain was measured. The primary outcomes were low back pain intensity and back related functioning measured with a numerical rating scale and the Roland Morris Disability Questionnaire, respectively. Secondary outcomes included health related quality of life scales measured with the Patient Reported Outcomes Measurement Information System, including scales for physical function, anxiety, depression, low energy/fatigue, sleep disturbance, participation in social roles and activities, and pain interference with activities. RESULTS: A total of 476 participants were included in this study. The mean age of participants at baseline was 54.0 years (standard deviation, ±13.2 years; range, 22-81 years). There were 349 (73.3%) female participants and 127 (26.7%) male participants in the study. Utilization of exercise therapy (odds ratio [OR], 0.37; 95% confidence interval [CI], 0.23-0.57), massage therapy (OR, 0.46; 95% CI, 0.25-0.83), and spinal manipulation (OR, 0.53; 95% CI, 0.29-0.93) decreased during the pandemic. A reduction in NSAID use was also observed (OR, 0.67; 95% CI, 0.45-0.99). Participants reported a significant, but not clinically relevant, improvement in low back pain intensity during the pandemic (mean improvement, 0.19; 95% CI, 0.03-0.34; Cohen's d, 0.11). However, White participants reported a significant improvement in low back pain intensity (mean improvement, 0.28; 95% CI, 0.10-0.46), whereas Black participants did not (mean improvement, -0.13; 95% CI, -0.46 to 0.19; p for interaction=0.03). Overall, there was a significant and clinically relevant improvement in pain interference with activities (mean improvement, 1.11; 95% CI, 0.20-2.02; Cohen's d, 0.20). The use of NSAIDs during the pandemic was associated with marginal increases in low back pain intensity. CONCLUSIONS: Overall, decreased utilization of treatments for chronic low back pain did not adversely impact pain and functioning outcomes during the first 6 months of the pandemic. However, Black participants experienced significantly worse pain outcomes than their White counterparts.

Knowledge and use of complementary therapies in a tertiary care hospital in France: A preliminary study.

Few studies have clarified the use of complementary therapies (CTs) in France. The main objective of this preliminary study was to evaluate knowledge of CTs in 4 representative groups of patients: patients suffering from cancer, patients presenting with a chronic noncancerous disease, chronic dialysis patients and nonchronic or cancerous patients needing surgery.A formalized questionnaire was designed by 2 psychologists, an oncologist and an anesthesiologist in charge of the Pain Clinic and Support Care Unit. One-hundred eleven patients were enrolled, and all agreed to complete the questionnaire.Eighty (72%) patients did not know the term "complementary therapies" (patients who were "not aware of CTs"), and 24 (21.6%) patients knew the term "complementary therapies" (patients who were "aware of CTs"), while 7 patients were not sure of the meaning. There were no differences between aware and unaware patients in gender (P = .27), age (P = .24), level of education (p = 0.24) or professional occupation (P = .06). Knowledge about CTs was significantly different among the different categories of patients (P = .03), with the only statistically significant difference between groups being between oncologic patients receiving ambulatory chemotherapy and patients presenting with a chronic noncancerous disease (P = .004).This preliminary study clearly highlights that patients and health caregivers are not aware of CTs and that there is a need for better communication about CTs.

Management of benign prostatic hyperplasia in the 21st century: temporal trends in Australian population-based data.

OBJECTIVE: To examine national trends in the medical and surgical treatment of benign prostatic hyperplasia (BPH) using Australian Medicare Benefits Schedule (MBS) and Pharmaceutical Benefits Scheme (PBS) population data from 2000 to 2018. PATIENTS AND METHODS: Annual data was extracted from the MBS, PBS and Australian Institute of Health and Welfare databases for the years 2000-2018. Population-adjusted rates of BPH procedures and medical therapies were calculated and compared in relation to age. Cost analysis was performed to estimate financial burden due to BPH. RESULTS: Overall national hospital admissions due to BPH declined between 2000 and 2018, despite an increased proportion of admissions due to private procedures (42% vs 77%). Longitudinal trends in the medical management of BPH showed an increased prescription rate of dutasteride/tamsulosin combined therapy (111 vs 7649 per 100 000 men) and dutasteride monotherapy (149 vs 336 per 100 000 men) since their introduction to the PBS in 2011. Trends in BPH surgery showed an overall progressive increase in rate of total procedures between 2000 and 2018 (92 vs 133 per 100 000 men). Transurethral resection of the prostate (TURP) remained the most commonly performed surgical procedure, despite reduced utilisation since 2009 (118 vs 89 per 100 000 men), offset by a higher uptake of photoselective vaporisation of prostate, holmium:YAG laser enucleation of prostate, and later likely due to minimally invasive surgical therapies including prostatic urethral lift and ablative technologies (including Rezum™). Financial burden due to BPH surgery has remained steady since 2009, whilst the burden due to medical therapy has risen sharply. CONCLUSION: Despite reduced national BPH-related hospitalisations, overall treatment for BPH has increased due to medical therapy and surgical alternatives to TURP. Further exploration into motivators for particular therapies and effect of medical therapy on BPH progression in clinical practice outside of clinical trials is warranted.

The effects of hands on and hands off/poised techniques on maternal outcomes: A systematic review and meta-analysis.

BACKGROUND: Negative maternal outcomes such as perineal trauma and related perineal pain may cause both long-and short- term morbidities. Hands on and hands off/poised technique are two kinds of techniques to protect perineum during the second-stage of labor. Hands on technique has been the routine midwifery practice for a long time; nevertheless, the effects of hands on technique on protecting perineum has been doubted. Hands off/poised as a promising technique seems prevalent in clinical practice. However, there is no consensus on use of hands off/poised technique and hands on technique. The effects of these techniques on maternal outcomes have not been fully investigated. OBJECTIVE: To evaluate the effects of hands on hands off/poised technique on maternal outcomes during the second-stage of labor. DESIGN: Systematic review and meta-analysis of relevant quantitative studies. DATA SOURCES: Seven databases: PubMed, EMBASE, The Cochrane Library, CINAHL, WanFang Data, China National Knowledge Infrastructure (CKNI), SinoMed were systematically searched from inception to July 23,2018 for relevant quantitative studies comparing the effects of hands on and hands off/poised technique on maternal outcomes. REVIEW METHODS: Quantitative studies were retrieved for relevant studies. Two reviewers independently screened the studies, evaluated the methodological quality using JBI appraisal checklist tools and extracted the data. The included studies were divided into two groups for analysis according to study types. RESULTS: Nine RCTs with a total of 7112 participants and eight non-RCTs with 37,786 participants were included for meta-analysis. Based on the results from RCTs, this study did not find difference between hands on and hands off/poised technique regarding the risk of 2nd perineal tears, 3rd /4th degree perineal tears, duration of second-stage labor and incidence of postpartum hemorrhage (PPH>500 ml). The results from 9 non-RCTs were similar with that of RCTs, except for showing less 2nd degree perineal tears in hands off/poised technique than in hands on technique. CONCLUSION: Evidence in the present study indicated that hands off/poised technique may be a promising delivery technique to maintain intact perineum, and reduce perineal pain and episiotomy use among women with low-risk pregnancy undergoing vaginal delivery. In addition, hands off/poised technique might be safe to use as it did not increase the risk of severe perineal trauma, postpartum hemorrhage, and longer duration of second-stage labor when compared with hands on technique. More studies with stringent study design, especially large randomized controlled trial, should be conducted before strong recommendation of the hands off/poised technique.

National management trends in clinical stage IIA nonseminomatous germ cell tumor (NSGCT) and opportunities to avoid dual therapy.

INTRODUCTION: For marker-negative clinical stage (CS) IIA nonseminomatous germ cell tumor (NSGCT), National Comprehensive Cancer Network and American Urological Association guidelines recommend either retroperitoneal lymph node dissection (RPLND) or induction chemotherapy. The goal is cure with one form of therapy. We evaluated national practice patterns in the management of CSIIA NSGCT and utilization of secondary therapies. METHODS: The National Cancer Data Base was used to identify 400 men diagnosed with marker negative CSIIA NSGCT between 2004 and 2014 treated with RPLND or chemotherapy. Trends in the utilization of initial and adjuvant treatment (chemotherapy only, RPLND only, RPLND with adjuvant chemotherapy, and postchemotherapy RPLND) were analyzed. RESULTS: Of the 400 cases, 233 (58%) underwent induction chemotherapy with surveillance, 51 (20%) underwent RPLND with surveillance, 89 (22%) underwent RPLND followed by adjuvant chemotherapy, and 14 (4%) underwent induction chemotherapy followed by RPLND. Thirty percent of patients received dual therapy. After RPLND with pN1 staging, 43 (61%) underwent adjuvant chemotherapy. The pN0 rate after primary RPLND was 22%. Five year overall survival ranged from 95% to 100% based on initial treatment choice. CONCLUSIONS: For marker negative CS IIA nonseminoma, dual, therapy, and treatment with chemotherapy is common. With low volume retroperitoneal disease resected at RPLND, adjuvant chemotherapy was frequently administered but has debatable therapeutic value. These data highlight opportunities to decrease treatment burden in patients with CS IIA nonseminoma.

Risk of Cardiovascular Events and Mortality Among Elderly Patients With Reduced GFR Receiving Direct Oral Anticoagulants.

RATIONALE & OBJECTIVE: Evidence for the efficacy of direct oral anticoagulants (DOACs) to prevent cardiovascular (CV) events and mortality in older individuals with a low estimated glomerular filtration rate (eGFR) is lacking. We sought to characterize the association of oral anticoagulant use with CV morbidity in elderly patients with or without reductions in eGFRs, comparing DOACs with vitamin K antagonists (VKAs). STUDY DESIGN: Population-based retrospective cohort study. SETTINGS & PARTICIPANTS: All individuals 66 years or older with an initial prescription for oral anticoagulants dispensed in Ontario, Canada, from 2009 to 2016. EXPOSURE: DOACs (apixaban, dabigatran, and rivaroxaban) compared with VKAs by eGFR group (≥60, 30-59, and<30mL/min/1.73m2). OUTCOMES: The primary outcome was a composite of a CV event (myocardial infarction, revascularization, or ischemic stroke) or mortality. Secondary outcomes were CV events alone, mortality, and hemorrhage requiring hospitalization. ANALYTICAL APPROACH: High-dimensional propensity score matching of DOAC to VKA users and Cox proportional hazards regression. RESULTS: 27,552 new DOAC users were matched to 27,552 new VKA users (median age, 78 years; 49% women). There was significantly lower risk for CV events or mortality among DOAC users compared with VKA users (event rates of 79.78 vs 99.77 per 1,000 person-years, respectively; HR, 0.82 [95% CI, 0.75-0.90]) and lower risk for hemorrhage (event rates of 10.35 vs 16.77 per 1,000 person-years, respectively; HR, 0.73 [95% CI, 0.58-0.91]). There was an interaction between eGFR and the association of anticoagulant class with the primary composite outcome (P<0.02): HRs of 1.01 [95% CI, 0.92-1.12], 0.83 [95% CI, 0.75-0.93], and 0.75 [95% CI, 0.51-1.10] for eGFRs of≥60, 30 to 59, and<30mL/min/1.73m2. No interaction was detected for the outcome of hemorrhage. LIMITATIONS: Retrospective observational study design limits causal inference; dosages of DOACs and international normalized ratio values were not available; low event rates in some subgroups limited statistical power. CONCLUSIONS: DOACs compared with VKAs were associated with lower risk for the composite of CV events or mortality, an association for which the strength was most apparent among those with reduced eGFRs. The therapeutic implications of these findings await further study.

Association of Neighborhood Measures of Social Determinants of Health With Breast, Cervical, and Colorectal Cancer Screening Rates in the US Midwest.

Importance: Despite advances in cancer treatment and cancer-related outcomes, disparities in cancer mortality remain. Lower rates of cancer prevention screening and consequent delays in diagnosis may exacerbate these disparities. Better understanding of the association between area-level social determinants of health and cancer screening may be helpful to increase screening rates. Objective: To examine the association between area deprivation, rurality, and screening for breast, cervical, and colorectal cancer in patients from an integrated health care delivery system in 3 US Midwest states (Minnesota, Iowa, and Wisconsin). Design, Setting, and Participants: In this cross-sectional study of adults receiving primary care at 75 primary care practices in Minnesota, Iowa, and Wisconsin, rates of recommended breast, cervical, and colorectal cancer screening completion were ascertained using electronic health records between July 1, 2016, and June 30, 2017. The area deprivation index (ADI) is a composite measure of social determinants of health composed of 17 US Census indicators and was calculated for all census block groups in Minnesota, Iowa, and Wisconsin (11 230 census block groups). Rurality was defined at the zip code level. Using multivariable logistic regression, this study examined the association between the ADI, rurality, and completion of cancer screening after adjusting for age, Charlson Comorbidity Index, race, and sex (for colorectal cancer only). Main Outcomes and Measures: Completion of recommended breast, cervical, and colorectal cancer screening. Results: The study cohorts were composed of 78 302 patients eligible for breast cancer screening (mean [SD] age, 61.8 [7.1] years), 126 731 patients eligible for cervical cancer screening (mean [SD] age, 42.6 [13.2] years), and 145 550 patients eligible for colorectal cancer screening (mean [SD] age, 62.4 [7.0] years; 52.9% [77 048 of 145 550] female). The odds of completing recommended screening were decreased for individuals living in the most deprived (highest ADI) census block group quintile compared with the least deprived (lowest ADI) quintile: the odds ratios were 0.51 (95% CI, 0.46-0.57) for breast cancer, 0.58 (95% CI, 0.54-0.62) for cervical cancer, and 0.57 (95% CI, 0.53-0.61) for colorectal cancer. Individuals living in rural areas compared with urban areas also had lower rates of cancer screening: the odds ratios were 0.76 (95% CI, 0.72-0.79) for breast cancer, 0.81 (95% CI, 0.79-0.83) for cervical cancer, and 0.93 (95% CI, 0.91-0.96) for colorectal cancer. Conclusions and Relevance: Individuals living in areas of greater deprivation and rurality had lower rates of recommended cancer screening, signaling the need for effective intervention strategies that may include improved community partnerships and patient engagement to enhance access to screening in highest-risk populations.

Exploring Variation in the Use of Conservative Management for Low-risk Prostate Cancer in the Veterans Affairs Healthcare System.

Current guidelines recommend conservative management as the preferred option for most low-risk prostate cancer cases, with certain possible exceptions (age <55yr, African Americans, and high-volume grade group 1). Although previous studies have documented substantial heterogeneity in the uptake of conservative management, less is known about the underlying reason for this variation and whether it is due to guideline-concordant factors (age, race, and biopsy cancer volume). We explored variation in the use of conservative management for low-risk prostate cancer among 20 597 men diagnosed in the US Veterans Affairs health care system from 2010 to 2016. Conservative management increased substantially over this time from 51% to 76% (p< 0.001). However, there was substantial variation by facility (35-100%). Multivariable analysis revealed that patient factors included in the guidelines (e.g., age and biopsy cores), other patient factors (eg, marital status and PSA) and non-patient factors (eg, geographic region, case volume, year) were associated with conservative management use. In conclusion, even within an integrated health care system, there remains significant heterogeneity in the uptake of conservative management for low-risk prostate cancer. Both guideline-concordant factors and other factors not discussed in the guidelines were associated with conservative management use. PATIENT SUMMARY: In the US Veterans Affairs health care system the vast majority of men with low-risk prostate cancer were managed conservatively by 2016, although there was significant variation by facility. Patient factors specifically mentioned in guidelines had the greatest impact on prediction of conservative management.

Vitamin D, Marine n-3 Fatty Acids, and Primary Prevention of Cardiovascular Disease Current Evidence.

Whether marine omega-3 fatty acid (n-3 FA) or vitamin D supplementation can prevent cardiovascular disease (CVD) in general populations at usual risk for this outcome is unknown. A major goal of VITAL (Vitamin D and Omega-3 Trial) was to fill this knowledge gap. In this article, we review the results of VITAL, discuss relevant mechanistic studies regarding n-3 FAs, vitamin D, and vascular disease, and summarize recent meta-analyses of the randomized trial evidence on these agents. VITAL was a nationwide, randomized, placebo-controlled, 2×2 factorial trial of marine n-3 FAs (1 g/d) and vitamin D3 (2000 IU/d) in the primary prevention of CVD and cancer among 25 871 US men aged ≥50 and women aged ≥55 years, including 5106 blacks. Median treatment duration was 5.3 years. Supplemental n-3 FAs did not significantly reduce the primary cardiovascular end point of major CVD events (composite of myocardial infarction, stroke, and CVD mortality; hazard ratio [HR], 0.92 [95% CI, 0.80-1.06]) but were associated with significant reductions in total myocardial infarction (HR, 0.72 [95% CI, 0.59-0.90]), percutaneous coronary intervention (HR, 0.78 [95% CI, 0.63-0.95]), and fatal myocardial infarction (HR, 0.50 [95% CI, 0.26-0.97]) but not stroke or other cardiovascular end points. For major CVD events, a treatment benefit was seen in those with dietary fish intake below the cohort median of 1.5 servings/wk (HR, 0.81 [95% CI, 0.67-0.98]) but not in those above (P interaction=0.045). For myocardial infarction, the greatest risk reductions were in blacks (HR, 0.23 [95% CI, 0.11-0.47]; P interaction by race, 0.001). Vitamin D supplementation did not reduce major CVD events (HR, 0.97 [95% CI, 0.85-1.12]) or other cardiovascular end points. Updated meta-analyses that include VITAL and other recent trials document coronary risk reduction from supplemental marine n-3 FAs but no clear CVD risk reduction from supplemental vitamin D. Additional research is needed to determine which individuals may be most likely to derive net benefit from supplementation. Clinical Trial Registration: URL: http://www.clinicaltrials.gov. Unique identifier: NCT01169259.

Antimicrobial resistance in cystic fibrosis: A Delphi approach to defining best practices.

BACKGROUND: Antimicrobial susceptibility testing (AST) is a cornerstone of infection management in cystic fibrosis. However, there is little evidence that AST predicts the clinical outcome of CF antimicrobial treatment. It has been suggested there is a need for careful consideration of current AST use by the CF community. METHODS: We engaged a group of experts consisting of pulmonary (adult and pediatric) and infectious disease clinicians, microbiologists, and pharmacists representing a broad international experience. We conducted an iterative systematic survey (Delphi) to determine and quantify consensus regarding key questions facing CF clinicians in the use of respiratory culture results including what tests to order, when to obtain them, and how to act upon the results of the testing. RESULTS: Consensus was reached for many questions but there was not universal agreement to the questions that were addressed. There were some differences with respect to cultures obtained for surveillance compared to when there is clinical worsening. Areas of general consensus include when and how respiratory cultures should be performed, what information should be reported, and when AST should be performed. A key finding is that clinical response to treatment is used to guide treatment decisions rather than AST results. CONCLUSIONS: Recommendations are presented regarding questions related to microbiology testing for patients with CF. We have also offered recommendations for priority research questions.

The Experience of Land and Water Birth Within the American Association of Birth Centers Perinatal Data Registry, 2012-2017.

Consumer demand for water birth has grown within an environment of professional controversy. Access to nonpharmacologic pain relief through water immersion is limited within hospital settings across the United States due to concerns over safety. The study is a secondary analysis of prospective observational Perinatal Data Registry (PDR) used by American Association of Birth Center members (AABC PDR). All births occurring between 2012 and 2017 in the community setting (home and birth center) were included in the analysis. Descriptive, correlational, and relative risk statistics were used to compare maternal and neonatal outcomes. Of 26 684 women, those giving birth in water had more favorable outcomes including fewer prolonged first- or second-stage labors, fetal heart rate abnormalities, shoulder dystocias, genital lacerations, episiotomies, hemorrhage, or postpartum transfers. Cord avulsion occurred rarely, but it was more common among water births. Newborns born in water were less likely to require transfer to a higher level of care, be admitted to a neonatal intensive care unit, or experience respiratory complication. Among childbearing women of low medical risk, personal preference should drive utilization of nonpharmacologic care practices including water birth. Both land and water births have similar good outcomes within the community setting.

Pediatric dermatologic surgery: our experience.

BACKGROUND: Surgical treatment for pediatric skin disorders is used for diagnostic and therapeutic reasons. We underline these procedures are usually easy and uncomplicated without the need for general anesthesia. Objective of this study was to share our experience in the field of pediatric dermatologic surgery. METHODS: We retrospectively analysed records of all pediatric patients receiving surgical therapy at the Dermatology Department of Spedali Civili of Brescia. Demographic data and treatments characteristics were recorded and analyzed. RESULTS: During the study period of one year, 670 surgical treatments concerning pediatric patients were collected. Number of procedures progressively grows with increasing age. All treatments were performed under local anesthesia except for a dermatofibrosarcoma protuberans for which general anesthesia was needed. CONCLUSIONS: Our data show that cryosurgery, electrodessication and excisional surgery constitute with equal proportion almost the whole of surgical procedures in dermatologic pediatric patients. Dermatologist's habit to perform surgery in local anesthesia avoids the risk of overtreatments, limits discomfort, anxiety, and pain perception linked to procedures performed.

Temporal Trends and Site Variation in High-Risk Coronary Intervention and the Use of Mechanical Circulatory Support: Insights From the Veterans Affairs Clinical Assessment Reporting and Tracking (CART) Program.

Background Patients undergoing percutaneous coronary intervention (PCI) are older with greater medical comorbidities and anatomical complexity than ever before, resulting in an increased frequency of nonemergent high-risk PCI (HR-PCI). We thus sought to evaluate the temporal trends in performance of HR-PCI and utilization of mechanical circulatory support in the largest integrated healthcare system in the United States. Methods and Results A cohort of high-risk adult patients that underwent nonemergent PCI in the Veterans Affairs Healthcare System between January 2008 and June 2018 were identified by objective clinical, hemodynamic, and anatomic criteria. Temporal trends in the performance of HR-PCI, utilization of mechanical circulatory support, and site-level variation were assessed. Of 111 548 patients assessed during the study period, 554 met 3 high-risk criteria whereas 4414 met at least 2 criteria for HR-PCI. There was a significant linear increase in the proportion of interventions that met 3 (P<0.001) or at least 2 (P<0.001) high-risk criteria over time, with rates approaching 1.9% and 11.2% in the last full calendar year analyzed. A minority of patients who met all high-risk criteria received PCI with mechanical support (15.7%) without a significant increase over time (P=0.193). However, there was significant site-level variation in the probability of performing HR-PCI (4.0-fold higher likelihood) and utilizing mechanical circulatory support (1.9-fold higher likelihood) between high and low utilization sites. Conclusions The proportion of cases categorized as HR-PCI has increased over time, with significant site-level variation in performance. The majority of HR-PCI cases did not utilize mechanical support, highlighting a discrepancy between current recommendations and clinical practice in an integrated healthcare system.

Use of nitrous oxide in children. / Bruk av lystgass hos barn.

BACKGROUND: In July 2013, the Department of Paediatric and Adolescent Medicine at Østfold Hospital Trust introduced nitrous oxide as an option for procedural sedation of children and adolescents. MATERIAL AND METHOD: During the period 13 July 2013-25 August 2017, 311 procedures were performed with nitrous oxide in 238 patients aged 4-17 years. Age, sex, type and duration of procedure, any supplementary medications, complications and whether the procedure would previously have required general anaesthesia, were recorded in a form. The child rated the effectiveness of nitrous oxide using a graded age-appropriate 10-point pain scale, and the nurse rated it as good, moderate or none. RESULTS: The children reported a median pain score of 2/10 (interquartile range 0-4), and nurses rated effectiveness as good in 247 of 304 (81 %) cases. For 43 % of procedures, the nurse felt that general anaesthesia would have been necessary had the department not had access to nitrous oxide. Adverse effects, most often dizziness, were reported in 110 of 311 procedures (35 %). In 7 of 311 procedures (2 %), the patient experienced adverse effects that resulted in stoppage of the procedure. The procedure was completed in 286 (92 %) children. INTERPRETATION: Nitrous oxide is a useful option for children who require procedural sedation, and means that more procedures can be performed without general anaesthesia.

Evaluation of nationwide referral pathways, investigation and treatment of suspected cauda equina syndrome in the United Kingdom.

Purpose: Cauda equina syndrome (CES) is a spinal emergency with clinical symptoms and signs that have low diagnostic accuracy. National guidelines in the United Kingdom (UK) state that all patients should undergo an MRI prior to referral to specialist spinal units and surgery should be performed at the earliest opportunity. We aimed to evaluate the current practice of investigating and treating suspected CES in the UK. Materials and Methods: A retrospective, multicentre observational study of the investigation and management of patients with suspected CES was conducted across the UK, including all patients referred to a spinal unit over 6 months between 1st October 2016 and 31st March 2017. Results: A total of 28 UK spinal units submitted data on 4441 referrals. Over half of referrals were made without any previous imaging (n = 2572, 57.9%). Of all referrals, 695 underwent surgical decompression (15.6%). The majority of referrals were made out-of-hours (n = 2229/3517, 63.4%). Patient location and pre-referral imaging were not associated with time intervals from symptom onset or presentation to decompression. Patients investigated outside of the spinal unit experienced longer time intervals from referral to undergoing the MRI scan. Conclusions: This is the largest known study of the investigation and management of suspected CES. We found that the majority of referrals were made without adequate investigations. Most patients were referred out-of-hours and many were transferred for an MRI without subsequently requiring surgery. Adherence to guidelines would reduce the number of referrals to spinal services by 72% and reduce the number of patient transfers by 79%.

[Appropriate use of vitamin D assessments in primary health care: Impact of new strategies for the introduction and follow-up of analyses in Östergötland]. / D-vitaminanalyser i primärvård måste användas ändamålsenligt - Ny strategi i Östergötland för införande och uppföljning av analyser gav bra resultat.

Systematic reviews and meta-analyses have shown that there is little justification for vitamin D supplements to prevent infections, cancer and cardiovascular disease. Despite the limited evidence of effectiveness, the total number of ordered serum 25-hydroxyvitamin D (25(OH)D) tests has increased considerably in recent years. There seems to be an overuse of this test that does not provide meaningful benefit for patients. A passive introduction of new tests leads generally to a slow initiation of value-based diagnostics, as well as overuse and underuse of diagnostic tests. In this study, in Region Östergötland, we applied a ¼Choosing wisely« model that reversed a rising trend of 25(OH)D tests and reduced the number of unnecessary tests. The findings point to the need for strategic plans for introducing new analyses and approaches to counteract misuse of laboratory diagnostics. We recommend ¼Choosing wisely« models for the introduction of new analyses to facilitate appropriate laboratory diagnostics and to counteract long-term overuse.

Nursing music intervention: A systematic mapping study.

OBJECTIVE: The present investigation analyses the studies of music intervention carried out by nurse researchers, or a research group including nurses, making use of a systematic mapping method to determine the trends in this field. METHOD: In this study, based on a systematic mapping method, 68 out of the 809 studies published between 2013 and 2017, were evaluated. RESULTS: In 87.7% of the studies, Receptive Music Therapy was used while new age music was listened to in 23.9% of the studies. Music intervention was found to be effective in relieving anxiety and pain in 54% and 34.1% of the 44 studies examining the efficacy of receptive music therapy, respectively. CONCLUSION: This study reveals that nurses use music intervention in all areas of health care services, and that the variables for which the effect of musical intervention is examined are mostly anxiety, vital signs and pain.
