This review aims to broadly describe drug infusion technologies and raise subtle but important issues arising from infusion therapy that can potentially lead to patient instability and morbidity. Advantages and disadvantages of gravity-dependent drug infusion are described and compared with electromechanical approaches for precise control of medication infusion, including large-volume peristaltic and syringe pumps. This review discusses how drugs and inert carriers interact within infusion systems and outlines several complexities and potential sources of drug error...

Lack of collaboration and communication can lead to medical errors, increased length of stay, and diminished patient satisfaction. The purpose of this project was to improve nurse efficiency, interdisciplinary communication and collaboration, and patient satisfaction with the discharge process through Rapid Rounds. The results demonstrated that interdisciplinary communication and collaboration improved coordination of care, as evidenced by improved Press Ganey percentile rankings for readiness for discharge and speed of the discharge process, increased pharmaceutical interventions, and fewer phone calls to physicians...

OBJECTIVES: Hearing loss contributes to suboptimal medical treatment. We investigated the nature and magnitude of potential health-care harm of hearing loss alone on a patient's understanding of medical consultations, investigations, and treatments of health conditions unrelated to their hearing loss. METHODS: A cross-sectional, questionnaire-based design of a convenience sample of students with hearing loss, registered with the institutional disability support service in 8 Irish and 15 UK third-level institutions...

Several factors contribute to individual variability in postoperative pain; therefore, individuals consume postoperative analgesics at different rates. Although many statistical studies have analyzed postoperative pain and analgesic consumption, most have identified only the correlation and have not subjected the statistical model to further tests in order to evaluate its predictive accuracy. In this study involving 3052 patients, a multistrategy computational approach was developed for analgesic consumption prediction...

PURPOSE: Tobacco smoking and nutrition are key lifestyle factors with long-term effects on eye health. However, little is known about patients' perceptions and experiences in these areas in relation to the care received from optometrists. The main aim was to survey patients' perceptions and prior experience regarding the role of optometrists in enquiring and providing advice about tobacco smoking and nutrition. METHODS: An anonymous, paper-based survey was distributed to a convenience sample of 225 adults attending the University of Melbourne eye care clinic...

BACKGROUND: Diagnostic errors appear to be the most common, costly, and dangerous of all medical mistakes. There has been a notable increase on the focus of error prevention as part of a growing patient safety movement. However, diagnostic errors have received less attention than other types of error. Our goal is to present a short mnemonic that can act as a checklist or posted reminder to help practitioners in dermatology or any field of medicine to avoid diagnostic errors. METHODS: To meet this goal, the authors reviewed the literature and discussed errors and potential errors they have experienced over 55 years of combined practice, to create a short mnemonic...

BACKGROUND: Recurrent anterior shoulder instability after coracoid process transfers may be caused by trauma, sports injury, or technical failure of the index procedure. Surgical techniques vary with regard to graft orientation and positioning and number of screws utilized for fixation. PURPOSE: To identify surgical and patient-related factors associated with failure, defined as the need for revision surgery. We hypothesized that failures will occur more commonly with single-screw fixation and graft malposition...

Mutations in somatic cells generate a heterogeneous genomic population and may result in serious medical conditions. Although cancer is typically associated with somatic variations, advances in DNA sequencing indicate that cell-specific variants affect a number of phenotypes and pathologies. Here, we show that mutagenic damage accounts for the majority of the erroneous identification of variants with low to moderate (1 to 5%) frequency. More important, we found signatures of damage in most sequencing data sets in widely used resources, including the 1000 Genomes Project and The Cancer Genome Atlas, establishing damage as a pervasive cause of sequencing errors...

Fetal growth restriction (FGR) is associated with an increased risk of perinatal morbidity and mortality and has lifetime implications for the risk of chronic medical conditions. Antenatal diagnosis of fetal growth restriction (FGR) remains poor with the majority of cases remaining undiagnosed. While several factors contribute to the underdiagnosis of FGR, the error in ultrasound estimation of fetal weight (EFW) is generally not considered in clinical practice. In this commentary, we suggest that the intrinsic, or systematic, error in ultrasound EFW is a significant factor contributing to the underestimation of fetuses predicted to have FGR and should be incorporated into screening and surveillance recommendations...

BACKGROUND: The causes of medication errors are unique in every clinical setting; hence error minimisation strategies are not always effective. For this reason, it is fundamental to understand the causes specific to the emergency department so that targeted strategies can be implemented. OBJECTIVES: To describe the contextual, modal, and psychological classification of medication errors in the emergency department to know the factors associated with the reported medication errors...

Obesity presents a growing challenge in critically ill patients because of variable medication pharmacokinetics and pharmacodynamics. Vasopressors used in the treatment of septic shock, including norepinephrine, are dosed using weight-based (WB) or non-weight-based (NWB) strategies. Retrospective research has evaluated the effect of total body weight and body mass index on vasopressor requirements, consequently finding that obese patients require less total vasopressor per kilogram to obtain clinical end points such as mean arterial pressure...

PURPOSE: Deformable multimodal image registration, which can benefit radiotherapy and image guided surgery by providing complementary information, remains a challenging task in the medical image analysis field due to the difficulty of defining a proper similarity measure. This article presents a novel, robust and fast binary descriptor, the discriminative local derivative pattern (dLDP), which is able to encode images of different modalities into similar image representations. METHODS: dLDP calculates a binary string for each voxel according to the pattern of intensity derivatives in its neighborhood...

BACKGROUND: Organizing work flow is a major task of laboratory management. Recently, clinical laboratories have started to adopt methodologies such as Lean Six Sigma and some successful implementations have been reported. This study used Lean Six Sigma to simplify the laboratory work process and decrease the turnaround time by eliminating non-value-adding steps. METHODS: The five-stage Six Sigma system known as define, measure, analyze, improve, and control (DMAIC) is used to identify and solve problems...

Demographic indicators forecast that by 2050, the elderly will account for about one-third of the global population. Geriatric patients require a large number of medicines, and in most cases, these products are administered as solid oral solid dosage forms, as they are by far the most common formulations on the market. However, this population tends to suffer difficulties with swallowing. Caregivers in hospital geriatric units routinely compound in solid oral dosage forms for dysphagic patients by crushing the tablets or opening the capsules to facilitate administration...

Learning to optimally predict rewards requires agents to account for fluctuations in reward value. Recent work suggests that individuals can efficiently learn about variable rewards through adaptation of the learning rate, and coding of prediction errors relative to reward variability. Such adaptive coding has been linked to midbrain dopamine neurons in nonhuman primates, and evidence in support for a similar role of the dopaminergic system in humans is emerging from fMRI data. Here, we sought to investigate the effect of dopaminergic perturbations on adaptive prediction error coding in humans, using a between-subject, placebo-controlled pharmacological fMRI study with a dopaminergic agonist (bromocriptine) and antagonist (sulpiride)...

Aseel S Abuzour, Penny J Lewis, Mary P Tully
BACKGROUND: Prescribing is a complex and error-prone task that demands expertise. McLellan et al.'s theory of expertise development model ("the model"), developed to assess medical literature on prescribing by medical students, proposes that in order to develop, individuals should deliberately engage their knowledge, skills and attitudes within a social context. Its applicability to independent prescribers (IP) is unknown. AIM: A systematic review was conducted to explore whether the model is applicable to non-medical independent prescribing and to assess the factors underpinning expertise development reported in the literature...

BACKGROUND: Cognitive deficits are well-documented in patients with bipolar disorder (BPD) and may impact the efficacy of psychotherapy. Cognitive control, a form of executive functioning, is often used therapeutically to shift patients' thoughts and behaviors from automatic, maladaptive responses to adaptive coping strategies. This study examined cognitive control processing in patients with BPD using the Multi-Source Interference Task (MSIT). METHOD: Twenty-nine patients diagnosed with BPD and 21 healthy control (HC) subjects completed the MSIT with concurrent functional magnetic resonance imaging (fMRI)...

The Institute of Medicine's 1999 report To Err Is Human shed light on the grave consequences of medical errors and led to a substantial increase in awareness in the federal government and private sector regarding medical errors. In addition, the literature contains myriad solutions, strategies, and recommendations for dealing with this problem; however, because of their complexity and inflexibility, most cannot be implemented and are inapplicable on an individual level. This essay proposes a seven-step pathway for preventing errors-a flexible, feasible, and organized method that can be used by healthcare administrators and providers...

OBJECTIVES: Although medication reconciliation has become standard during hospital admission, rates of unintentional medication discrepancies during intensive care of pediatric patients with chronic disease are unknown. Such discrepancies are an important cause of adverse drug events in adults with chronic illness and are associated with unintentional discontinuation of chronic medications. We sought to determine the rate, type, timing, and predictors of potentially harmful unintentional medication discrepancies in children and young adults with chronic disease...
