A qualitative exploration of nurse's perception of Critical Outreach Service: a before and after study.

BACKGROUND Critical Care Outreach Services (CCOS) have been reported to streamline the transfer of patients from the intensive care unit (ICU) to the wards and provide a follow-up service supporting ward staff to provide optimum care for patients discharged from ICU. PURPOSE The aim of this study was to explore the perceptions of nursing staff before and after the introduction of a CCOS at three adult teaching hospitals in Perth, Western Australia. METHODS Exploratory focus groups were conducted with registered nurses (RNs) at each of the participating hospitals prior to and 6 months after the introduction of a CCOS. Framework analysis was used to analyse the transcribed data using a thematic approach with themes developed from the narratives of the participants. RESULTS Inexperienced RNs in particular voiced positive comments about the CCOS. The role was seen as a senior nurse who was an additional resource for less experienced staff as they educated them on complex procedures that were not common on the general wards. The RNs reported that apprehensions about the role that they had pre-implementation were not borne out in practice and that they believed that the CCOS had positive effects on patient outcomes. CONCLUSION The CCOS improved communication processes between members of the multidisciplinary team and units within the hospital, which subsequently enhanced the ward transition process for critically ill patients and ward nursing staff.

Clinical Effectiveness of a Critical Care Nursing Outreach Service in Facilitating Discharge From the Intensive Care Unit

BACKGROUND Improved discharge planning and extension of care to the general care unit for patients transferring from intensive care may prevent readmission to the intensive care unit and prolonged hospital stays. Morbidity, mortality, and costs increase in readmitted intensive care patients. OBJECTIVES To evaluate the clinical effectiveness of a critical care nursing outreach service in facilitating discharge from the intensive care unit and providing follow-up in general care areas. METHODS A before-and-after study design (with historical controls and a 6-month prospective intervention) was used to ascertain differences in clinical outcomes, length of stay, and cost/benefit. Patients admitted to intensive care units in 3 adult teaching hospitals were recruited. The service centered on follow-up visits by specialist intensive care nurses who reviewed and assessed patients who were to be or had been discharged to general care areas from the intensive care unit. Those nurses also provided education and clinical support to staff in general care areas. RESULTS In total, 1435 patients were discharged during the 6-month prospective period. Length of stay from the time of admission to the intensive care unit to hospital discharge (P = .85), readmissions during the same hospital admission (5.6% vs 5.4%, P = .83), and hospital survival (P = .80) did not differ from before to after the intervention. CONCLUSIONS Although other studies have shown beneficial outcomes in Australia and the United Kingdom, we found no improvement in length of stay after admission to the intensive care unit, readmission rate, or hospital mortality after a critical care nursing outreach service was implemented.

Discharge delay, room for improvement?

AIM Patients treated in the intensive care unit (ICU) and identified as suitable for discharge to the ward should have their discharge planned and expedited to improve patient outcomes and manage resources efficiently. We examined the hypothesis that the introduction of a critical care outreach role would decrease the frequency of discharge delay from ICU. METHODS Discharge delay was compared for two 6-month periods: (1) after introduction of the outreach role in 2008 and (2) in 2000/2001 (from an earlier study). Patients were included if discharged to a ward in the study hospital. Discharge times and reason for delay were collected by Critical Care Outreach Nurses and Critical Care Nurse Specialists. RESULTS Of the 516 discharges in 2008 (488 patients compared to 607 in 2000/2001), 31% of the discharges were delayed from ICU more than 8h, an increase of 6% from 2000/2001 (p<0.001). Patients in 2008 spent more in hospital from the time of their ICU admission when their discharge was delayed (p<0.001). The most common reasons for delay in 2008 were due to no bed or delay in bed availability (53%) and medical concern (24%). This is in contrast to 2000/2001 when 80% of delays were due to no bed or delay in bed availability and 9% due to medical concern. Many factors impact on patient flow and reducing ICU discharge delays requires a collaborative, multi-factorial approach which adapts to changing organisational policy on patient flow through ICU and the hospital, not just the discharge process in ICU.

Reducing interruptions to continuous enteral nutrition in the intensive care unit: a comparative study

AIMS AND OBJECTIVES To develop and test strategies to reduce interruptions to enteral feeding to improve practice and promote attainment of nutritional goals. BACKGROUND Enteral nutrition is preferred for feeding patients in the intensive care unit who are unable to have oral nutrition. Interruption to feeding is likely to be a major contributor to patients not receiving their prescribed nutrition goals. DESIGN Prospective before (May-November 2009) and after (March-September 2010) study. METHOD Patients admitted to the intensive care unit (except cardiac surgery) and who were eligible to receive enteral nutrition were enrolled. After gaining Ethics Committee approval, baseline data were collected to identify interruptions to enteral nutrition. Nurse-led multidisciplinary teams developed interventions to target specific reasons for interruption. Change champions implemented the improvements after staff were provided with an education package. Postintervention data were then collected. RESULTS Six hundred and fifty-three patients received enteral nutrition with the majority (88%) fed within 48 hours. Considering the first 28 days of feeding for patients fed longer than 24 hours (505 patients), the number of interruptions for patients who had an interruption decreased from 907-662. Interruptions due to gastrointestinal issues decreased (14 vs 10%), while those due to airway issues, enteral nutrition delivery system problems and other interruptions were similar before-and-after the practice change. Time lost to feeding because of interruptions was similar between groups. CONCLUSION Targeted strategies to enteral feeding practice resulted in a reduction to the number of interruptions but not the duration of enteral nutrition lost to interruption. Reducing unnecessary interruption of feeding circuits is likely to minimise the risk for splash injury and contamination of feeding sets through less manipulation and interruption to enteral nutrition flow. RELEVANCE TO CLINICAL PRACTICE Review of practice may reveal opportunities for improvement. Nurse champions can facilitate change processes to improve care.

Frequency of Aspirating Gastric Tubes for Patients Receiving Enteral Nutrition in the ICU A Randomized Controlled Trial

BACKGROUND Enteral nutrition (EN) tolerance is often monitored by aspirating stomach contents by syringe at prescribed intervals. No studies have been conducted to assess the most appropriate time interval for aspirating gastric tubes. We compared gastric tube aspirations every 4 hours (usual care) with a variable regimen (up to every 8 hours aspirations). METHODS This randomized controlled trial (RCT) enrolled patients who stayed in the intensive care unit (ICU) for >48 hours, had a gastric tube, and were likely to receive EN for 3 or more days. Patients were randomized (computer-generated randomization) to either the control (every 4 hours) or intervention group (variable regimen). The primary outcome was number of gastric tube aspirations per day from randomization until EN was ceased or up to 2 weeks postrandomization. RESULTS Following Institutional Ethics Committee approval, 357 patients were recruited (control group, n = 179; intervention group, n = 178). No differences were found in age, sex, worst APACHE II score, or time to start of EN. In the intention-to-treat analysis, the intervention group had fewer tube aspirations per day (3.4 versus 5.4 in the control group, P < .001). Vomiting/regurgitation was increased in the intervention group (2.1% versus 3.6%, P = .02). There were no other differences in complications. CONCLUSION This is the first RCT to examine the frequency of gastric tube aspirations. The frequency of gastric tube aspirations was reduced in the variable-regimen group with no increase in risk to the patient. Reducing the frequency of aspirations saves nursing time, decreases risk of contamination of feeding circuit, and minimizes risk of body fluid exposure.

Early experience with influenza A H1N109 in an Australian intensive care unit

Summary Influenza is a common seasonal viral infection that affects large numbers of people. In early 2009, many people were admitted to hospitals in Mexico with severe respiratory failure following an influenza-like illness, subtyped as H1N1. An increased mortality rate was observed. By June 2009, H1N1 was upgraded to pandemic status. In June–July, Australian ICUs were experiencing increased activity due to the influenza pandemic. While hospitals implemented plans for the pandemic, the particularly heavy demand to provide critical care facilities to accommodate an influx of people with severe respiratory failure became evident and placed a great burden on provision of these services. This paper describes the initial experience (June to mid September) of the pandemic from the nursing perspective in a single Australian ICU. Patients were noted to be younger with a higher proportion of women, two of whom were pregnant. Two patients had APACHE III comorbidity. Of the 31 patients admitted during this period, three patients died in ICU and one patient died in hospital. Aerosol precautions were initiated for all patients. The requirement for single room accommodation placed enormous demands for bed management in ICU. Specific infection control procedures were developed to deal with this new pandemic influenza.
