Technology meets tradition: The perceived impact of the introduction of information and communication technology on ward rounds in the intensive care unit.

BACKGROUND: Public policy in many health systems is currently dominated by the quest to find ways to 'do more with less'-to achieve better outcomes at a reduced cost. The success or failure of initiatives in support of this quest are often understood in terms of an adversarial dynamic or struggle between the professional logics of medicine and of management. Here, we use the case of the introduction of information and communication technology (ICT) to a well-established ritual of medical autonomy (the medical ward round) to articulate a more nuanced explanation of how and why new ways of working with technology are accepted and adopted (or not). METHODS: The study was conducted across four intensive care units (ICUs) in major teaching hospitals in Sydney, Australia. Using interviews, we examined 48 doctors' perceptions of the impact of ICT on ward round practice. We applied the concept of institutional logics to frame our analysis. Interview transcripts were analysed using a hybrid of deductive and inductive thematic analysis. RESULTS: The doctors displayed a complex engagement with the technology that belies simplistic characterisations of medical rejection of managerial encroachment. In fact, they selectively welcomed into the ward round aspects of the technology which reinforced the doctor's place in the healthcare hierarchy and which augmented their role as scientists. At the same time, they guarded against allowing managerial logic embedded in ICT to de-emphasise their embodied subjectivity in relation to the patient as a person rather than as a collection of parameters. CONCLUSION: ICT can force the disruption of some aspects of existing routines, even where these are long-established rituals. Resistance arose when the new technology did not fit with the 'logic of care'. Incorporation of the logic of care into the design and customisation of clinical information systems is a challenge and potentially counterproductive, because it could attempt to apply a technological fix to what is essentially a social problem. However, there are significant opportunities to ensure that new technologies do not obstruct doctors' roles as carers nor disrupt the embodied relationship they need to have with patients.

What do ICU doctors do? A multisite time and motion study of the clinical work patterns of registrars.

OBJECTIVE: To quantify the time that intensive care unit registrars spend on different work tasks with other health professionals and patients and using information resources, and to compare them with those of clinicians in general wards and the emergency department (ED). DESIGN, SETTING AND PARTICIPANTS: A prospective, observational time-and-motion study of two ICUs with a total of 71 beds at two major teaching hospitals in Sydney. Twenty-six registrars were observed between 08:00 and 18:00 on weekdays for a total of 160.52 hours. MAIN OUTCOME MEASURES: Proportions of time spent on different tasks, using specific information resources, working with other health professionals and patients, and rates of multitasking and interruptions. RESULTS: A total of 12 043 distinct tasks were observed. Registrars spent 69.2% of time working at patients' bedsides, 49.6% in professional communication and 39.0% accessing information resources. Half of their time (53.8%) was spent with other ICU doctors and 29.2% with nurses. Compared with doctors and nurses on general wards, and doctors in the ED, ICU registrars were more likely to multitask (40.1 times/hour [24.4% of their time]). ICU registrars had a higher interruption rate than ward clinicians, (4.2 times/hour), but a lower rate than ED doctors. CONCLUSIONS: Face-to-face communication and information seeking consume a vast proportion of ICU registrars' time. Multitasking and handling frequent interruptions characterise their work, and such behaviours may create an increased risk of task errors. Electronic clinical information systems may be particularly beneficial in this information-rich environment.

The effect of endotracheal tube size on voice and swallowing function in patients with thermal burn injury: an evaluation using the Australian Therapy Outcome Measures (AusTOMS).

The objective of this study was to determine if intubation using larger endotracheal tube sizes in mechanically ventilated patients with thermal burn injury adversely affects voice and swallowing function. This prospective, observational study was conducted in patients with thermal burn injuries, who were mechanically ventilated via an endotracheal tube. The primary outcome measures were changes in voice and swallowing function, assessed using the Australian Therapy Outcome Measures (AusTOMS), immediately before the burn injury, and 12 months after the removal of the endotracheal tube. Of 101 patients screened, 20 male patients were followed for 12 months. Patients intubated with size 8.0 or larger endotracheal tubes were compared to patients with size 7.5 endotracheal tubes or smaller. Patients with the larger endotracheal tubes had a significant 1.8-point (9%) decline in their AusTOMS voice score (p =.01) using the paired t-test, but there was no significant difference between the two groups using the independent samples t-test. There was no significant difference in swallowing outcome between the two groups. Male patients with thermal burn injuries, mechanically ventilated using size 8.0 endotracheal tubes or larger, had a statistically significant decline in voice outcome; however, interpretation of this result is limited by methodological considerations.

An ICU clinical information system - clinicians' expectations and perceptions of its impact.

The Intensive Care Unit (ICU) is an information intense environment where Clinical Information Systems (CISs) can greatly impact patient care and the workload of clinicians. With the introduction of an ICU CIS imminent across New South Wales hospitals, we aimed to understand how ICU clinicians perceived a new system would impact on work practices in Australian ICUs, as much of the current evidence is generated from overseas. We conducted interviews with 66 doctors and nurses in 3 ICUs without a CIS. Many had positive perceptions regarding the impact of its introduction, though others were more guarded and unsure. Clinicians believed information access to patient would improve, communication processes could potentially change and there was potential for work processes to be more efficient. It was expected that ward rounds and handover would be less disrupted with all information available at the bedside or at the handover setting. There were mixed responses about whether a CIS would save time and how it would influence patient care, though the majority believed a CIS would improve safety by providing a means for increasing accountability and reducing medication errors. Concerns were raised about the transition from paper to a CIS and the training required. This information provides valuable evidence in the Australian setting regarding clinicians' expectations of a new ICU CIS to assist with future implementations. It also provides baseline data as a foundation for future research once the CIS is implemented. It is clear that robust quantitative studies are required to gain a detailed understanding of how a new CIS will impact clinicians' work processes and that appropriate training is crucial for full benefits to be achieved.

Expansion of a medical emergency team system to a mental health facility.

BACKGROUND: Clinical emergency response systems such as medical emergency teams (MET) are used in many hospitals worldwide, but the effect that these systems have in mental health facilities is unknown. This study examined the rate and nature of MET calls to a mental health facility that had relocated to the campus of a tertiary referral hospital. METHODS: This study was a prospective, observational study of MET calls to a newly constructed 170 bed mental health facility. Data were collected on the number and nature of MET calls to the facility. RESULTS: Over 24 months, there were 66 MET calls to the mental health facility, and 1217 MET calls at the main hospital. The mean MET call rate was 14.2 calls per 1000 admissions (95% confidence interval (CI) 10.8-17.7) at the mental health facility, and 14.7 calls per 1000 admissions (95% CI 13.9-15.5) at the main hospital. Neurological and cardiovascular problems were present in 61% and 41% of MET calls. CONCLUSION: The rate of MET calls to a new mental health facility can be similar to that of a tertiary hospital. Staff attending MET calls need to be prepared to manage predominantly neurological and cardiovascular problems.

Palliative care teams in the intensive care unit: a randomised, controlled, feasibility study.

OBJECTIVES: To determine whether palliative care teams can improve patient, family and staff satisfaction for patients receiving end-of-life care in the intensive care unit and reduce surrogate markers of health care costs. DESIGN: Randomised controlled, feasibility study. SETTING: 14-bed general ICU over 29 months in 2006-2008. PARTICIPANTS: Patients admitted with a terminal or preterminal condition, for whom the treating intensivist considered that escalating or continuing treatment was unlikely to achieve significant improvement in the patient's clinical condition. INTERVENTION: A consultation from a palliative care team, in addition to usual ICU end-of-life care. MAIN OUTCOME MEASURES: ICU and hospital length of stay, and changes in composite scores of satisfaction obtained from questionnaires administered to families, nursing staff and intensivists. RESULTS: The study was constrained by significant logistical and methodological problems, including low recruitment and questionnaire completion rates, and the lack of an available validated questionnaire. From a total of 2009 admissions over a 29-month period, 20 patients were enrolled, 10 in each group. There were significant differences in baseline characteristics. There were no statistically significant differences between those who had a consultation with the palliative care team and those who did not in median ICU length of stay (3 days v 5 days, P=0.97), median hospital length of stay (5 days v 11 days, P=0.44), or changes in overall composite satisfaction scores reported by families (-6% v -6%, P=0.91), nursing staff (+5% v +15%, P=0.30), and intensivists (-2% v +2%, P=0.42). CONCLUSION: This feasibility study was difficult to conduct and did not generate any robust conclusions about the utility of involving palliative care teams in end-of-life care in the ICU. Larger studies are technically possible but unlikely to be feasible. TRIAL REGISTRATION: Australian Clinical Trials Registry ACTRN012606000110583.

Operator anaesthesiology training and complications after endotracheal intubation in the intensive care unit: a 3-year, prospective, observational study.

OBJECTIVE: To determine whether operators with less than 3 months' formal anaesthesiology training have higher rates of complications when performing endotracheal intubation (ETI) in the intensive care unit than operators with longer formal anaesthesiology training. DESIGN AND SETTING: Prospective, single-centre, observational study of consecutive ETIs performed in a general, urban, tertiary ICU between May 2005 and May 2008. Data were collected by self-reported, written questionnaire. PARTICIPANTS: The two pre-defined study cohorts were ETIs performed where the initial operator had less than 3 months' formal training in anaesthesiology, and those where the initial operator had 3 months' or longer training. MAIN OUTCOME MEASURES: The primary outcome measure was the number of ETIs where one or more pre-defined complications occurred as a result of the ETI. Secondary outcome measures were the number of ETIs where one or more respiratory, cardiovascular or trauma complications occurred as a result of the ETI, and the number where the airway was deemed difficult by the operator. RESULTS: Data were collected on 276 ETIs. There were no significant differences in primary or secondary outcome measures between the two main study groups. Operators with less than 3 months' formal training in anaesthesiology had a higher level of medical supervision or assistance (75% v 29%, P<0.001), more favourable patient pre-intubation oxygen saturation on pulse oximetry (SpO(2)) (76% v 65% had SpO(2)>89%, P=0.05), and easier resultant grade of intubation (70% v 56% of intubations were Grade I, P= 0.04), but required more operators (19% v 3% required two operators, P<0.001), and more attempts before ETI was successful (62% v 82% of intubations were successful on first attempt, P<0.001). CONCLUSION: ETIs performed in the ICU where the initial operator has less than 3 months' formal training in anaesthesiology appear not to be associated with more complications. However, this may be attributable to less experienced operators having more assistance and supervision, and to patient selection.

Effect of implementation of a weekly multidisciplinary team meeting in a general intensive care unit.

OBJECTIVE: To determine whether the introduction of a weekly multidisciplinary team meeting (MDTM) to a general intensive care unit improved selected clinical indicators of patient outcome, and staff satisfaction with patient care. DESIGN: A single-centre, observational, before-and-after study. SETTING: A 14-bed general ICU in an urban, tertiary teaching hospital. STUDY POPULATION: All patients admitted to the ICU during June-December 2006 (before the intervention) and June- December 2007 (after the intervention), and staff employed in the ICU in December 2006 and December 2007. INTERVENTION: Introduction of a weekly MDTM to the ICU. MAIN OUTCOME MEASURES: The primary outcome was the number of patients who stayed in the ICU longer than 5 days. Secondary outcomes included nurses' scores for satisfaction with patient care on a questionnaire; ICU and hospital mortality; duration of mechanical ventilation; readmissions to the ICU within 72 hours of discharge; and after-hours discharges. RESULTS: There were 376 ICU admissions in the "before" period and 432 in the "after" period. Baseline characteristics of the two groups were similar except for a lower proportion of patients admitted directly to the ICU from the operating theatres in the after period (34.2% v 45.2%, P = 0.002). There were no significant differences in any of the primary or secondary outcomes, with the exception of one questionnaire score: a fall in the score nursing staff gave for value of all meetings held in the ICU following the introduction of the MDTM (from 6.6 to 3.9 on a scale of 0-10, P = 0.001). CONCLUSION: The introduction of a weekly MDTM to a general ICU did not improve selected clinical indicators of patient outcome or staff satisfaction with patient care.

Survival after out-of-hospital cardiac arrest in Sydney, Australia.

BACKGROUND: Out-of-hospital cardiac arrest (OHCA) is a significant cause of death, but there is little published information on its incidence and outcomes in Australia. AIM: This study was undertaken to determine the incidence and survival from OHCA in Sydney, New South Wales. METHODS: Patients listed on the Ambulance Service of NSW database as having an OHCA during the 12-month period 1 June 2004 to 31 May 2005 were matched with the NSW Registry of Births, Deaths and Marriages to determine if they had died, and how long they survived. Survival was also determined for patients aged 80 years or older, and for the presenting electrocardiograph (ECG) rhythm. RESULTS: OHCAs were recorded for 2011 people in a population of 3.993 million. The age-standardised incidence was 52.6 events per 100,000 person-years (95% CI, 51.6-53.6). Incidence was significantly higher in older age groups. Only 24% of patients survived past the day of the OHCA. Survival for 28 days, 90 days and 1 year was 12.6%, 12.2%, and 11.5%, respectively. Survival was highest when the presentation ECG was ventricular fibrillation. Patients aged 80 years or older had lower survival rates. CONCLUSION: Survival from OHCA in Sydney is low, and lower in patients aged 80 years or older. The incidence of OHCA in Sydney is similar to that in the rest of the world. Mortality occurs early after OHCA. Hence, for interventions to be effective in improving survival, they need to be targeted at the early stages of OHCA.
