Characterizing medication safety incidents in surgical patients: a retrospective cross-sectional analysis of incident reports.

Background: Medication-related safety incidents (MSIs) are among the most frequent contributors to preventable harm in hospital patients. There is a paucity of research that explores the factors that contribute to MSIs across the departments of high-risk specialties such as surgery.

Objectives: To characterize MSIs involving surgical patients across two secondary care sites at a University Health Board.

Patient, Provider, and Clinic Characteristics Associated with Opioid and Non-Opioid Pain Prescriptions for Patients Receiving Low Back Imaging in Primary Care.

Background: To describe characteristics of patients, providers, and clinics associated with opioid or non-opioid pain medication prescribing patterns for patients who received lower spine imaging in primary care clinics.

Methods: In these secondary analyses of the Lumbar Imaging with Reporting of Epidemiology (LIRE) study, a randomized controlled trial conducted in 4 health systems in the United States, we evaluated characteristics associated with receipt of pain medication prescriptions. The outcomes were receipt of prescriptions for opioid or, separately, non-opioid pain medications within 90 days after imaging.

Expected Organizational Costs for Inserting Prevalence Information Into Lumbar Spine Imaging Reports.

Background: Modifying physician behavior to more closely align with guideline-based care can be challenging. Few effective strategies resulting in appropriate spine-related health care have been reported. The Lumbar Imaging With Reporting of Epidemiology (LIRE) intervention did not result in reductions in spine care but did in opioid prescriptions written.

Accounting for quality improvement during the conduct of embedded pragmatic clinical trials within healthcare systems: NIH Collaboratory case studies.

Embedded pragmatic clinical trials (ePCTs) and quality improvement (QI) activities often occur simultaneously within healthcare systems (HCSs). Embedded PCTs within HCSs are conducted to test interventions and provide evidence that may impact public health, health system operations, and quality of care. They are larger and more broadly generalizable than QI initiatives, and may generate what is considered high-quality evidence for potential use in care and clinical practice guidelines.

Reduction in massive postpartum haemorrhage and red blood cell transfusion during a national quality improvement project, Obstetric Bleeding Strategy for Wales, OBS Cymru: an observational study.

Background: Postpartum haemorrhage (PPH) is a major cause of maternal morbidity and mortality and its incidence is increasing in many countries despite management guidelines. A national quality improvement programme called the Obstetric Bleeding Strategy for Wales (OBS Cymru) was introduced in all obstetric units in Wales. The aim was to reduce moderate PPH (1000 mL) progressing to massive PPH (> 2500 mL) and the need for red cell transfusion.

Providing Epidemiological Data in Lumbar Spine Imaging Reports Did Not Affect Subsequent Utilization of Spine Procedures: Secondary Outcomes from a Stepped-Wedge Randomized Controlled Trial.

Objective: To evaluate the effect of inserting epidemiological information into lumbar spine imaging reports on subsequent nonsurgical and surgical procedures involving the thoracolumbosacral spine and sacroiliac joints.

Design: Analysis of secondary outcomes from the Lumbar Imaging with Reporting of Epidemiology (LIRE) pragmatic stepped-wedge randomized trial.

Setting: Primary care clinics within four integrated health care systems in the United States.

Effects of Including Epidemiologic Data in Lumbar Spine Imaging Reports on Prescribing Non-Opioid Medications for Pain.

Background: Information on the prevalence of common imaging findings among patients without back pain in spine imaging reports might affect pain medication prescribing for patients with back pain. Prior research on inserting this text suggested a small reduction in opioid prescribing.

Objective: To evaluate the effect of epidemiologic information in spine imaging reports on non-opioid pain medication prescribing for primary care patients with back pain.

Incidence of postpartum haemorrhage defined by quantitative blood loss measurement: a national cohort.

Background: Visual estimation of blood loss following delivery often under-reports actual bleed volume. To improve accuracy, quantitative blood loss measurement was introduced for all births in the 12 hospitals providing maternity care in Wales. This intervention was incorporated into a quality improvement programme (Obstetric Bleeding Strategy for Wales, OBS Cymru).

Designing and implementing an all Wales postpartum haemorrhage quality improvement project: OBS Cymru (the Obstetric Bleeding Strategy for Wales).

Background: Postpartum haemorrhage (PPH) contributes to substantial maternal morbidity. Research into PPH has led to improvements in care which have been incorporated into the Obstetric Bleeding Strategy for Wales.

Intervention: A national quality improvement team supported local teams in implementing multiple interventions including risk assessment, objective measurement of blood loss, multiprofessional assessment (at the bedside at 1000 mL blood loss) and point-of-care (POC) testing of coagulation to guide blood product resuscitation during PPH.

Association of Allergic Rhinitis With Change in Nasal Congestion in New Continuous Positive Airway Pressure Users.

Importance: Nasal congestion occurring after continuous positive airway pressure (CPAP) treatment initiation impairs CPAP adherence. Allergic rhinitis is associated with worsening nasal congestion in patients who are exposed to nonallergic triggers. Use of CPAP presents potential nonallergic triggers (eg, humidity, temperature, pressure, and airflow).

RAPID INDUCTION ANALGESIA FOR CAPSAICIN-INDUCED PAIN IN UNIVERSITY STUDENTS: A Randomized, Controlled Trial.

The effect of rapid-induction analgesia (RIA) hypnosis on capsaicin-induced pain was tested in 60 healthy volunteers allocated randomly to 1 of 3 conditions: listening to an RIA recording several times before and then during the session, only the in-session RIA intervention, or listening to relaxing music (the control condition). Participants who had listened to the RIA recording beforehand were significantly more relaxed than controls when differences between the groups were identified for pain intensity. These findings suggest that relaxation induced by RIA recordings can alleviate the affective component of pain.

Comparison of Natural Language Processing Rules-based and Machine-learning Systems to Identify Lumbar Spine Imaging Findings Related to Low Back Pain.

Rationale And Objectives: To evaluate a natural language processing (NLP) system built with open-source tools for identification of lumbar spine imaging findings related to low back pain on magnetic resonance and x-ray radiology reports from four health systems.

Materials And Methods: We used a limited data set (de-identified except for dates) sampled from lumbar spine imaging reports of a prospectively assembled cohort of adults. From N = 178,333 reports, we randomly selected N = 871 to form a reference-standard dataset, consisting of N = 413 x-ray reports and N = 458 MR reports.

Long-term outcomes of a large, prospective observational cohort of older adults with back pain.

Background Context: Although back pain is common among older adults, there is relatively little research on the course of back pain in this age group.

Purpose: Our primary goals were to report 2-year outcomes of older adults initiating primary care for back pain and to examine the relative importance of patient factors versus medical interventions in predicting 2-year disability and pain.

Study Design/setting: This study used a predictive model using data from a prospective, observational cohort from a primary care setting.

Pragmatic clinical trials embedded in healthcare systems: generalizable lessons from the NIH Collaboratory.

Background: The clinical research enterprise is not producing the evidence decision makers arguably need in a timely and cost effective manner; research currently involves the use of labor-intensive parallel systems that are separate from clinical care. The emergence of pragmatic clinical trials (PCTs) poses a possible solution: these large-scale trials are embedded within routine clinical care and often involve cluster randomization of hospitals, clinics, primary care providers, etc. Interventions can be implemented by health system personnel through usual communication channels and quality improvement infrastructure, and data collected as part of routine clinical care.

Using Natural Language Processing of Free-Text Radiology Reports to Identify Type 1 Modic Endplate Changes.

Electronic medical record (EMR) systems provide easy access to radiology reports and offer great potential to support quality improvement efforts and clinical research. Harnessing the full potential of the EMR requires scalable approaches such as natural language processing (NLP) to convert text into variables used for evaluation or analysis. Our goal was to determine the feasibility of using NLP to identify patients with Type 1 Modic endplate changes using clinical reports of magnetic resonance (MR) imaging examinations of the spine.

The History of Archives and the History of Science: Comment.

Drawing on Terry Cook's famous challenge to the relationship of historians to the archive, this comment responds to the four preceding Focus essays, offering an examination of the roles, in particular, of acquisition and appraisal, canon formation, and place or location in the relationship that historians of science have with the archive.

Predicting CPAP Use and Treatment Outcomes Using Composite Indices of Sleep Apnea Severity.

Study Objectives: Measures of baseline sleep apnea disease burden (apnea-hypopnea index, Epworth Sleepiness Scale) predict continuous positive airway pressure (CPAP) adherence, but composite indices of sleep apnea severity (Sleep Apnea Severity Index, Modified Sleep Apnea Severity Index) may be more robust measures of disease burden. We tested the relative prognostic ability of each measure of sleep apnea disease burden to predict subsequent CPAP adherence and subjective sleep outcomes.

Methods: Prospective cohort study at a tertiary academic sleep center.

Lumbar Imaging With Reporting Of Epidemiology (LIRE)--Protocol for a pragmatic cluster randomized trial.

Background: Diagnostic imaging is often the first step in evaluating patients with back pain and likely functions as a "gateway" to a subsequent cascade of interventions. However, lumbar spine imaging frequently reveals incidental findings among normal, pain-free individuals suggesting that treatment of these "abnormalities" may not be warranted. Our prior work suggested that inserting the prevalence of imaging findings in patients without back pain into spine imaging reports may reduce subsequent interventions.

Association of early imaging for back pain with clinical outcomes in older adults.

Importance: In contrast to the recommendations for younger adults, many guidelines allow for older adults with back pain to undergo imaging without waiting 4 to 6 weeks. However, early imaging may precipitate interventions that do not improve outcomes.

Objective: To compare function and pain at the 12-month follow-up visit among older adults who received early imaging with those who did not receive early imaging after a new primary care visit for back pain without radiculopathy.

Back pain in seniors: the Back pain Outcomes using Longitudinal Data (BOLD) cohort baseline data.

Background: Back pain represents a substantial burden globally, ranking first in a recent assessment among causes of years lived with disability. Though back pain is widely studied among working age adults, there are gaps with respect to basic descriptive epidemiology among seniors, especially in the United States. Our goal was to describe how pain, function and health-related quality of life vary by demographic and geographic factors among seniors presenting to primary care providers with new episodes of care for back pain.

Exploratory study to identify the process used by pharmacy staff to verify the accuracy of dispensed medicines.

Objectives: To determine the common stages and strategies involved in the dispensing accuracy-checking process used by pharmacy staff and to determine the training activities used by these staff to gain the knowledge and skills for accuracy checking.

Method: Face-to-face tape-recorded ethnographic interviews (n = 28) were undertaken in 2009-2010 at two large teaching hospitals with a purposive sample of pharmacists and accredited checking technicians qualified to undertake the final accuracy check on dispensed medicines. Participants described their accuracy-checking process, strategies used to aid checking using anonymised prescriptions and accurate dispensing of medicines to aid discussion.
