Impact of sepsis education for healthcare professionals and students on learning and patient outcomes: a systematic review.

BACKGROUND: Sepsis is an important global healthcare problem that is a key challenge faced by healthcare professionals face worldwide. One key effort aimed at reducing the global burden of sepsis is educating healthcare professionals about early identification and management of sepsis. AIM: To provide a comprehensive evaluation of sepsis education among healthcare professionals and students. METHODS: Six databases (PubMed, CINAHL, Embase, MEDLINE, Cochrane Central Register of Controlled Trials, and Scopus) were searched. We included studies that described and evaluated any form of education or training on sepsis delivered to healthcare professionals and students. Study outcomes were summarized according to the adapted Kirkpatrick model of training evaluation. RESULTS: Thirty-two studies were included in the review. The learning contents were reported to be in accordance with the Surviving Sepsis Campaign guidelines. Seven studies included the topic of interprofessional teamwork and communication in their sepsis education content. Most educational programmes were effective and reported positive effects on immediate knowledge outcomes. Interventions that were delivered through an active learning approach such as simulation and game-based learning generally produced greater gains than didactic teaching. Improvements in patient care processes and patient outcomes were associated with the concomitant existence or implementation of a hospital sepsis care bundle. CONCLUSION: Incorporating active learning strategies into sepsis education interventions has the potential to improve learners' long-term outcomes. In addition, sepsis education and a protocol-based sepsis care bundle act in synergy to augment greater improvements in care processes and patient benefits.

Lipidomic Analysis of Archival Pathology Specimens Identifies Altered Lipid Signatures in Ovarian Clear Cell Carcinoma.

Cancer metabolism is associated with the enhanced lipogenesis required for rapid growth and proliferation. However, the magnitude of dysregulation of diverse lipid species still requires significant characterization, particularly in ovarian clear cell carcinoma (OCCC). Here, we have implemented a robust sample preparation workflow together with targeted LC-MS/MS to identify the lipidomic changes in formalin-fixed paraffin-embedded specimens from OCCC compared to tumor-free ovarian tissue. We quantitated 340 lipid species, representing 28 lipid classes. We observed differential regulation of diverse lipid species belonging to several glycerophospholipid classes and trihexosylceramide. A number of unsaturated lipid species were increased in OCCC, whereas saturated lipid species showed a decrease in OCCC compared to the controls. We also carried out total fatty acid analysis and observed an increase in the levels of several unsaturated fatty acids with a concomitant increase in the index of stearoyl-CoA desaturase (SCD) in OCCC. We confirmed the upregulation of SCD (the rate-limiting enzyme for the synthesis of monounsaturated fatty acids) by immunohistochemistry (IHC) assays. Hence, by carrying out a mass spectrometry analysis of archival tissue samples, we were able to provide insights into lipidomic alterations in OCCC.

Calf Compartment Syndrome associated with the Use of an Intra-osseous Line in an Adult Patient: A Case Report.

We present a case of a lower limb compartment syndrome associated with the use of an intra-osseous line inserted into the proximal tibia in an adult patient. An unconscious 59-year old male with multiple injuries presented to our Emergency Department after a road traffic accident. Bilateral proximal tibial intra osseous-lines were inserted due to poor venous access. After resuscitation his left leg was noted to be tense and swollen with absent pulses. Acute compartment syndrome was diagnosed both clinically and with compartment pressure measurement. Two incision fasciotomy on his left lower leg was performed. Intra osseous-lines in the proximal tibia are increasingly used in adult patients in the pre-hospital setting by paramedics and emergency physicians. Their use, along with the possible complications of these devices, such as the development of compartment syndrome or osteomyelitis leading to amputation, is well reported in the paediatric literature. To the best of our knowledge, there have not been any previous reports of complications in the adult patient. We present a case of lower leg compartment syndrome developing from the use of an intra-osseous line in the proximal tibia in an adult patient. With the increasing use of intra-osseous lines in adult patients, clinicians should be aware of the possibility of developing compartment syndrome which may lead to disability or amputation in severe cases.

Front line nurses' experiences with deteriorating ward patients: a qualitative study.

BACKGROUND: Nurses in the general ward are faced with patients who are at high risk of clinical deterioration. Having the key role in performing routine vital signs monitoring, non-registered nurses such as enrolled nurses are the front line nurses who play a pivotal role in detecting and responding to the deteriorating ward patient. AIMS: (1) To explore the experience of enrolled nurses with deteriorating patients in pre-cardiac arrest situations and (2) to identify strategies to enhance their role in caring for deteriorating ward patients. METHOD: A qualitative study using critical incident technique was conducted. Fifteen enrolled nurses who had encountered deteriorating ward patients were interviewed. Data were analysed using content analysis. FINDINGS: Three themes emerged describing enrolled nurse's experience with deteriorating patients: recognizing deterioration, responding to deterioration and taking responsibility. Two themes, including educational development and modifying clinical processes, were strategies identified to enhance the ability of enrolled nurses in recognizing and managing deteriorating patients. CONCLUSION: The study highlighted a need to enhance the ability of front line nurses in recognizing and responding to patient deterioration through nursing education and modifications of clinical processes. IMPLICATIONS FOR NURSING AND HEALTH POLICY: Nursing education could focus on increasing the awareness of the importance of performing complete vital signs monitoring and undertaking accurate interpretation of vital signs. Strategies to improve clinical processes could include the need for registered nurses to provide supervision of enrolled nurses in the interpretation of vital signs readings and share the responsibility of performing vital signs monitoring.

Strabismus-related prejudice in 5-6-year-old children.

AIMS: There is a general consensus that individuals with conspicuous strabismus are perceived more negatively with respect to physical appearance, personality and capability. Such social biases can potentially lead to social alienation and negative psychosocial development, particularly when experienced at a young age. This study aims to explore young children's perception of peers with noticeable exotropia. METHODS: 128 children, 5-6 years old, took part in this cross-sectional within-group study. The sample viewed four paired images of peers with orthotropia and exotropia, and chose the image they LIKED and the image they would SHARE their favourite toy with. All images were created using digital morphing technique. RESULTS: Single proportion tests showed that a significantly greater proportion of the sample chose the orthotropic images as the ones they like (z=5.74, p<0.001) and the ones they would share their favourite toy with (z=4.90, p<0.001). Phi coefficient analysis further demonstrated an association between the choice to like and the choice to share ((504)=0.34, p<0.001). CONCLUSIONS: Children as young as 5 years old are found to have negative social reactions towards peers with noticeable exotropia. These findings imply that children with noticeable strabismus may be subjected to social alienation at an early age.

Estrogen for schizophrenia.

BACKGROUND: In terms of clinical outcomes, women with schizophrenia seem to fare better then men, but appear more vulnerable to psychotic illness in the period after birth and menopause. As these vulnerable periods to psychosis are associated with estrogen withdrawal, this hormone has been proposed as a treatment for schizophrenia. OBJECTIVES: To evaluate the clinical effects of estrogens alone or in combination with progesterone, as a sole treatment or as an adjunctive therapy, for the treatment of schizophrenia or schizophrenia-like illnesses. SEARCH STRATEGY: Electronic searches of the Cochrane Schizophrenia Group's Register (October 2003) was supplemented with manual reference inspection of all identified studies. Authors of trials were contacted for further material and archive information. SELECTION CRITERIA: All randomised clinical trials comparing estrogens with or without progesterone, as a sole or adjunctive treatment for people with schizophrenia or other similar serious, non-affective psychotic illness. DATA COLLECTION AND ANALYSIS: We evaluated data independently and analysed on an intention to treat basis. For binary data we calculated the fixed effect relative risk (RR) and its 95% confidence interval (CI). For continuous non-skewed data, we calculated weighted mean differences. MAIN RESULTS: All available evidence relates to women. Four studies (n=108) compared estrogen only with placebo. Short-term scores for general mental state showed no significant difference between groups (n=24, 1 RCT, WMD PANSS for 100mcg comparison -2.26 CI -15.4 to 10.9). Data from all four studies showed overall loss from the studies was low ( 5%), with no significant differences between groups (n=96, 4 RCTs, RR 0.95 CI 0.2 to 6.1). Skewed continuous data from two studies showed no clear differences in ratings of movement disorders. One medium-term unpublished study (n=14) compared estrogen and progesterone with placebo. Data at six months showed no difference between groups for total scores (n=9, WMD PANSS -25.3 CI -51 to 0.1). For negative symptoms, results favoured the estrogen and progesterone group (n=9, WMD PANSS negative subscale -9.0 CI -17 to -0.9). For loss to follow up there was no difference between groups (n=10, RR 0.33 CI 0.02 to 6.7). This trial used many cognitive tests and one visual retention test showed statistically significant differences favouring the treatment group: total scores (n=8, WMD -3.5 CI -5.7 to -1.3). AUTHORS' CONCLUSIONS: Adjunctive estrogen with or without progesterone does not appear to offer convincing advantages over placebo. Before any more research is undertaken in this area, all completed and unpublished work should be made available in order to ensure that more trials are justified.

A defective endotracheal tube.

Routine inspection and testing of endotracheal tubes prior to use may fail to detect certain manufacturing defects. We describe a case of endotracheal tube kinking at the junction where the inflation tube for the pilot balloon is attached to the endotracheal tube. This case report highlights the importance of maintaining an awareness that airway obstruction or leak due to structural defects can still occur even with high quality, prepacked single use plastic endotracheal tubes. It also emphasises the need to have a systematic approach when dealing with such critical events.

Sexually transmitted diseases and condom use among female freelance and brothel-based sex workers in Singapore.

BACKGROUND AND OBJECTIVES: Most studies in Asia exclude freelance female sex workers because of difficulties in access and the illegality of their work. Data are lacking on their risk behaviors. GOAL: To compare sexually transmitted disease (STD) rates, condom use, and health screening behavior between freelance and brothel-based sex workers in Singapore. STUDY DESIGN: This is a cross-sectional survey of 111 free-lance sex workers arrested from November 1996 to March 1997 for illicit prostitution and 333 randomly selected brothel-based sex workers. All were tested for STDs. RESULTS: STDs were significantly more prevalent among freelance than brothel-based sex workers (34.8% vs. 24.0%). Inconsistent condom use was significantly higher among freelance than brothel-based sex workers and was significantly associated with younger age, decreasing number of clients, and perception of non-condom use among peers. CONCLUSION: Educational programs to promote condom use should target freelance sex workers and their clients.

PIP: This study compares the prevalence of sexually transmitted diseases (STDs), condom use, and health-screening behavior between freelance and brothel-based sex workers in Singapore. A total of 111 female freelance sex workers arrested from November 1996 to March 1997 for illicit prostitution were interviewed; 333 brothel-based sex workers served as the comparison group for the analysis. STD test results revealed that freelance sex workers (34.8%) have higher STD rates than brothel-based sex workers (24%). The two most common STDs in both groups were chlamydial cervicitis and syphilis. Moreover, condom use was significantly lower among freelance sex workers than brothel-based sex workers and was associated with younger age (25 years old), decreasing number of clients, and perception of non-condom use among peers. In addition, freelance workers were more educated and had equally high knowledge on STDs and AIDS. Since most of these freelance workers practice high-risk behaviors and poor health screening behaviors such as not going for regular medical check-ups, STD services and education programs should target this group.
