Mid- and long-term clinical results of surgical therapy in unicameral bone cysts
<p>Abstract</p> <p>Background</p> <p>Unicameral (or simple) bone cysts (UBC) are benign tumours most often located in long bones of children and adolescents. Pathological fractures are common, and due to high recurrence rates, these lesions remain a challenge to treat. Numerous surgical procedures have been proposed, but there is no general consensus of the ideal treatment. The aim of this investigation therefore was to study the long-term outcome after surgical treatment in UBC.</p> <p>Methods</p> <p>A retrospective analysis of 46 patients surgically treated for UBC was performed for short and mid-term outcome. Clinical and radiological outcome parameters were studied according to a modified Neer classification system. Long-term clinical information was retrieved via a questionnaire at a minimum follow-up of 10 years after surgery.</p> <p>Results</p> <p>Forty-six patients (17 female, 29 male) with a mean age of 10.0 ± 4.8 years and with histopathologically confirmed diagnosis of UBC were included. Pathological fractures were observed in 21 cases (46%). All patients underwent surgery for UBC (35 patients underwent curettage and bone grafting as a primary therapy, 4 curettage alone, 3 received corticoid instillation and 4 decompression by cannulated screws). Overall recurrence rate after the first surgical treatment was 39% (18/46), second (17.4% of all patients) and third recurrence (4.3%) were frequently observed and were addressed by revision surgery. Recurrence was significantly higher in young and in male patients as well as in active cysts. After a mean of 52 months, 40 out of 46 cysts were considered healed. Prognosis was significantly better when recurrence was observed later than 30 months after therapy. After a mean follow-up of 15.5 ± 6.2 years, 40 patients acknowledged clinically excellent results, while five reported mild and casual pain. Only one patient reported a mild limitation of range of motion.</p> <p>Conclusions</p> <p>Our results suggest satisfactory overall long-term outcome for the surgical treatment of UBC, although short-and mid-term observation show a considerable rate of recurrence independent of the surgical technique.</p
Development of a context model to prioritize drug safety alerts in CPOE systems
Background: Computerized physician order entry systems (CPOE) can reduce the number of medication errors and adverse drug events (ADEs) in healthcare institutions. Unfortunately, they tend to produce a large number of partly irrelevant alerts, in turn leading to alert overload and causing alert fatigue. The objective of this work is to identify factors that can be used to prioritize and present alerts depending on the 'context' of a clinical situation. Methods: We used a combination of literature searches and expert interviews to identify and validate the possible context factors. The internal validation of the context factors was performed by calculating the inter-rater agreement of two researcher's classification of 33 relevant articles. Results: We developed a context model containing 20 factors. We grouped these context factors into three categories: characteristics of the patient or case (e. g. clinical status of the patient); characteristics of the organizational unit or user (e. g. professional experience of the user); and alert characteristics (e. g. severity of the effect). The internal validation resulted in nearly perfect agreement (Cohen's Kappa value of 0.97). Conclusion: To our knowledge, this is the first structured attempt to develop a comprehensive context model for prioritizing drug safety alerts in CPOE systems. The outcome of this work can be used to develop future tailored drug safety alerting in CPOE systems

Midwives' attitudes towards giving weight-related advice to obese pregnant women
It is estimated that 1 in 5 pregnant women are obese, this poses a significant risk to maternal, fetal and newborn mortality and morbidity and as such, maternal obesity is recognised as a challenge for contemporary and prospective maternity services. As key practitioners in maternity care, midwives are seen as frontline professionals delivering weight-related advice to obese pregnant women. This study aimed to explore midwives' attitudes towards offering obese pregnant women weight-related advice during pregnancy and the puerperium. Nine midwives were interviewed using an in-depth interview schedule. Data were analysed using Colaizzi's (1978) seven-stage thematic approach. Midwives' knowledge of risk associated with maternal obesity was good; advice giving was mainly confined to community practice; the amount and consistency of advice was determined by: women's responses, women's apparent motivation to change and midwives' self-perception as a role model. Four key themes emerged: challenges for practice; perceived proficiency; advice giving skills and midwives' perceived relationship with a woman. Midwives need to address personal issues around body image, as they appear to hinder advice giving, before they can develop effective communication techniques to be able to offer obese pregnant women weight-related advice. The recommendation is to investigate ways in which issues of body image influence midwives ability to offer weight-related advice
