Trends in candidemia and antifungal susceptibility in a university hospital in Northern Ireland 2001-2006

Objectives: To describe the species distribution and antifungal susceptibility trends for documented episodes of candidemia at the Royal Hospitals, Belfast, 2001-2006. Methods: Laboratory-based retrospective observational study of all episodes of candidemia. Results: There were 151 episodes of candidemia. The species recovered were: 96 C. albicans; 26 C. glabrata; 18 C. parapsilosis; five C. tropicalis; four C. guilliermondii; one C. famata and one C. dubliniensis. We separated the data into two periods 2001-2003 and 2004-2006; contrary to the findings of other investigators, there was a notable trends toward increasing frequency of C. albicans and decreasing frequency of non-albicans species over time. Although the proportion of C. albicans, C. parapsilosis and C. tropicalis isolates susceptible to fluconazole was unchanged over time, a trend of decreased susceptibility of C. glabrata to fluconazole was noted over the six-year period. Overall, 73% and 7.7% of C. glabrata isolates had susceptible-dose-dependent and resistant phenotypes, respectively. The percentage of C. glabrata isolates susceptible to fluconazole (MIC

Resource utilisation, length of hospital stay, and pattern of investigation during acute medical hospital admission

Hierarchical VHDL libraries for DSP ASIC design

Methods are presented for the rapid design of DSP ASICs based on the use of hierarchical VHDL libraries. These are portable across many silicon foundries and allow complex DSP silicon systems to be developed in a fraction of the time normally required. Resulting designs are highly competitive with ones created using conventional methods. The approach is illustrated by its application to ADPCM codec and DCT cores.

Rapid design of DSP ASIC cores using hierarchical VHDL libraries

Methods are presented for the rapid design of DSP ASICs based on the use of a series of hierarchical VHDL libraries which are portable across many silicon foundries. These allows complex DSP silicon systems to be developed in a small fraction of the time normally required. Resulting designs are highly competitive with those developed using more conventional methods. The approach is illustrated using several examples. These include ADPCM codecs, as well as DCT and FFT cores.

Perceived causes of prescribing errors by junior doctors in hospital inpatients:a study from the PROTECT programme

Prescribing errors are a major cause of patient safety incidents. Understanding the underlying factors is essential in developing interventions to address this problem. This study aimed to investigate the perceived causes of prescribing errors among foundation (junior) doctors in Scotland.

Who makes prescribing decisions in hospital inpatients?:An observational study

Errors involving drug prescriptions are a key target for patient safety initiatives. Recent studies have focused on error rates across different grades of doctors in order to target interventions. However, many prescriptions are not instigated by the doctor who writes them. It is important to clarify how often this occurs in order to interpret these studies and create interventions. This study aimed to provisionally quantify and describe prescriptions where the identity of the decision maker and prescription writer differed.

Through the lens of the hospital magazine - Downshire and Holywell psychiatric hospitals in the 1960s and 1970s

An exploration of the pages of two psychiatric hospital magazines, Speedwell from Holywell Hospital, Antrim, and The Sketch from Downshire Hospital, Downpatrick, reveals the activity filled lives of patients and staff during the 1960s and 1970s. This was a time of great change in mental health care. It was also a time of political turbulence in Northern Ireland. With large in-patient populations, both hospitals had a range of occupational and sporting activities available to patients and staff. The magazines formed part of the effort to promote the ethos of a therapeutic community. While hospital magazines may be viewed as one aspect of an institutional system that allowed people to cut themselves from the wider society, they also provided opportunities for budding writers to express their views on life in a hospital from the service user perspective. As such they offer some valuable insights into the lives of psychiatric patients.

Expression of Toll-Like Receptors 2 and 4 is Upregulated During Hospital Admission in Traumatic Patients:Lack of Correlation with Blunted Innate Immune Responses

Background: There are reports with conflicting results on the expression of toll-like receptors (TLRs) in trauma patients. In addition, these studies analyzed TLR expression only at patients hospital admission but not later when complications usually arise. Objectives: To analyze the surface expression of TLR2 and TLR4 on circulating monocytes from trauma patients during the hospitalization period and to correlate this with cytokine production after stimulation with TLR2 and TLR4 agonists. The phagocytic capacity of monocytes was analyzed at the same time points of TLR expression analysis; to correlate these molecular findings with the presence or absence of infections. Methods: Prospective and observational study from June 2005 to June 2007. In all analysis, a control group composed of healthy subjects was included. Results: We studied 70 trauma patients admitted to the intensive care unit (ICU) of a tertiary hospital, and 30 healthy volunteers. Blood samples were collected at hospital admission, on day 7 and 14. Forty-four patients (63%) developed at least one episode of infection. Monocytes from trauma patients expressed higher levels of TLR2 and TLR4 than monocytes from control subjects at all time points. Expression of TLR2 and TLR4 in monocytes from those patients who developed any infection was significantly lower than in those patients without infection but still significantly higher than in control subjects. Cellular responses to TLR4 agonist were impaired. Monocytes from traumatic patients phagocytosized less efficiently than monocytes from control subjects. Conclusions: These results indicate that trauma patients present a dysregulation of the innate immune system that persists during the first 14 days after hospital admission.

Assessing family members' satisfaction with information sharing and communication during Hospital care at the end of life

Context: Despite the fact that most deaths occur in hospital, problems remain with how patients and families experience care at the end of life when a death occurs in a hospital. Objectives: (1) assess family member satisfaction with information sharing and communication, and (2) examine how satisfaction with information sharing and communication is associated with patient factors. Methods: Using a cross-sectional survey, data were collected from family members of adult patients who died in an acute care organization. Correlation and factor analysis were conducted, and internal consistency assessed using Cronbach's alpha. Linear regression was performed to determine the relationship among patient variables and satisfaction on the Information Sharing and Communication (ISC) scale. Results: There were 529 questionnaires available for analysis. Following correlation analysis and the dropping of redundant and conceptually irrelevant items, seven items remained for factor analysis. One factor was identified, described as information sharing and communication, that explained 76.3% of the variance. The questionnaire demonstrated good content and reliability (Cronbach's alpha 0.96). Overall, family members were satisfied with information sharing and communication (mean total satisfaction score 3.9, SD 1.1). The ISC total score was significantly associated with patient gender, the number of days in hospital before death, and the hospital program where the patient died. Conclusions: The ISC scale demonstrated good content validity and reliability. The ISC scale offers acute care organizations a means to assess the quality of information sharing and communication that transpires in care at the end of life. © Copyright 2013, Mary Ann Liebert, Inc.

An outpatient respiratory rehabilitation program:Findings from a community hospital

Objectives: To determine patient satisfaction with a community hospital's respiratory rehabilitation program and to assess changes in patient physical and emotional function and quality of life. Design: Pre- and post-program measures were made on a variety of physiological and psychosocial factors. A modified version of the Chronic Respiratory Disease Questionnaire was administered before and after the 8-week multidisciplinary and comprehensive respiratory rehabilitation program. The post-program questionnaire also included a number of service delivery and patient satisfaction and quality-of-life questions. Setting: Respiratory Rehabilitation Program at St. Joseph's Hospital, a community hospital in Brantford, Ont., in active partnership with the Brant County Lung Association. Brant County is located in Central West Ontario, and has both urban and rural areas and a population of approximately 125 000 people. Participants: Twenty-nine patients, with a diagnosis of moderate to severe chronic obstructive pulmonary disease (COPD) who were referred to the Fall 1997 and Spring 1998 programs, were enrolled in the study. Outcome measures: Changes in physical and emotional function, health knowledge, skills mastery, quality of life and satisfaction with the program. Results: Twenty-one of 29 patients completed the program. Statistically significant and clinically important improvements were found between all pre- and post-program evaluation scores (distance walked, fatigue, dyspnea, emotional function, skills mastery and health knowledge). Participants were very satisfied with the program and felt it improved their quality of life. Conclusion: The positive outcomes reported rom randomized controlled trials of respiratory rehabilitation programs can be achieved in a community hospital setting.

New challenges faced by carers during their child's hospital admission under segregation

Introduction
This paper presents the results of a qualitative study of CF family carers at the Belfast Paediatric CF Centre. The aim of this study was to describe the carer experience of their child’s admission to hospital under segregated care arrangements, and to highlight the meaning of segregation and cross infection from the carer perspective.

Method
Carers of children with CF who were admitted for two week IV antibiotic treatment during the study period were eligible to participate in this qualitative study. A consecutive series of eligible carers were approached in order of admission and within the time constraints of KR who was present two days each week. Recruitment of carers ended when no new themes emerged. Ten carers, 9 mothers and 1 couple, were interviewed about their experiences (mean age of child: 11.8 years; range: 1-17 years). Interpretative Phenomenological Analysis (IPA) was used to analyse and interpret the interview data.

Results and discussion
Balancing demands and dilemmas was the main contextual theme or experience of being a carer of a child with CF, and particularly so during admission to hospital. Many decisions were required every day that resulted in ‘double binds’ comprising uncertainty and stress. Three secondary themes captured the essence of carers’ experiences specifically related to segregation: managing risk and uncertainty; the burden of admission; and getting through each day. These themes will be described with examples illustrating the challenges faced by carers during their child’s hospitalisation, and the impact of segregation upon carers.
