Problems associated with nursing staff shortage: an analysis of the first 3600 incident reports submitted to the Australian Incident Monitoring Study (AIMS-ICU)

Association between intensive care unit nursing grade and mortality in patients with cardiogenic shock and its cost-effectiveness

BACKGROUND

Despite the high workload of cardiac intensive care unit (ICU), there is a paucity of evidence on the association between nurse workforce and mortality in patients with cardiogenic shock (CS). This study aimed to evaluate the prognostic impact of the ICU nursing grade on mortality and cost-effectiveness in CS.

METHODS

A nationwide analysis was performed using the K-NHIS database. Patients diagnosed with CS and admitted to the ICU at tertiary hospitals were enrolled. ICU nursing grade was defined according to the bed-to-nurse ratio: grade1 (bed-to-nurse ratio < 0.5), grade2 (0.5 ≤ bed-to-nurse ratio < 0.63), and grade3 (0.63 ≤ bed-to-nurse ratio < 0.77) or above. The primary endpoint was in-hospital mortality. Cost-effective analysis was also performed.

RESULTS

Of the 72,950 patients with CS, 27,216 (37.3%) were in ICU nursing grade 1, 29,710 (40.7%) in grade 2, and 16,024 (22.0%) in grade ≥ 3. The adjusted-OR for in-hospital mortality was significantly higher in patients with grade 2 (grade 1 vs. grade 2, 30.6% vs. 37.5%, adjusted-OR 1.14, 95% CI1.09-1.19) and grade ≥ 3 (40.6%) with an adjusted-OR of 1.29 (95% CI 1.23-1.36) than those with grade 1. The incremental cost-effectiveness ratio of grade1 compared with grade 2 and ≥ 3 was $25,047/year and $42,888/year for hospitalization and $5151/year and $5269/year for 1-year follow-up, suggesting that grade 1 was cost-effective. In subgroup analysis, the beneficial effects of the high-intensity nursing grade on mortality were more prominent in patients who received CPR or multiple vasopressors usage.

CONCLUSIONS

For patients with CS, ICU grade 1 with a high-intensity nursing staff was associated with reduced mortality and more cost-effectiveness during hospitalization compared to grade 2 and grade ≥ 3, and its beneficial effects were more pronounced in subjects at high risk of CS.

Medication Safety in Two Intensive Care Units of a Community Teaching Hospital After Electronic Health Record Implementation: Sociotechnical and Human Factors Engineering Considerations

OBJECTIVE

The aim of the study was to assess the impact of Electronic Health Record (EHR) implementation on medication safety in two intensive care units (ICUs).

METHODS

Using a prospective pre-post design, we assessed 1254 consecutive admissions to two ICUs before and after an EHR implementation. Each medication event was evaluated with regard to medication error (error type, medication-management stage) and impact on patient (severity of potential or actual harm).

RESULTS

We identified 4063 medication-related events either pre-implementation (2074 events) or post-implementation (1989 events). Although the overall potential for harm due to medication errors decreased post-implementation only 2 of the 3 error rates were significantly lower post-implementation. After EHR implementation, we observed reductions in rates of medication errors per admission at the stages of transcription (0.13-0, P < 0.001), dispensing (0.49-0.16, P < 0.001), and administration (0.83-0.56, P = 0.011). Within the ordering stage, 4 error types decreased post-implementation (orders with omitted information, error-prone abbreviations, illegible orders, failure to renew orders) and 4 error types increased post-implementation (orders of wrong drug, orders containing a wrong start or stop time, duplicate orders, orders with inappropriate or wrong information). Within the administration stage, we observed a reduction of late administrations and increases in omitted administrations and incorrect documentation.

CONCLUSIONS

Electronic Health Record implementation in two ICUs was associated with both improvement and worsening in rates of specific error types. Further safety improvements require a nuanced understanding of how various error types are influenced by the technology and the sociotechnical work system of the technology implementation. Recommendations based on human factors engineering principles are provided for reducing medication errors.

Effect of Nursing Workload in Intensive Care Units

Nursing work efforts are important in providing sound healthcare services, especially in the intensive care units (ICU). Complications and adverse events are more liable to occur among patients in the ICU and these patients require more attention and nursing care. Most of the research in this field is mainly focused on the effect of staffing and its correlation to patient safety and satisfaction. Previous studies also showed that reduced nursing staffing was significantly associated with the development of pneumonia in ICU patients who needed more nursing requirements. An increase in nursing workload is also significantly associated with an increased incidence rate of nosocomial infections. The association between nursing workload in ICU patients and increased incidence rates of mortality is also supported by previous studies. The nurse-to-patient ratio has been previously used to evaluate patient safety correlation with the nursing workload as reported by previous reports. However, previous research shows that the nursing workload is a more complex correlation and can not be determined by a simple ratio as the nurse-to-patient one. Evidence shows that many adverse events may occur with patients in the ICU secondary to reduced nursing care such as increased mortality, length of hospital stay, and catching in-hospital infections. In the current study, we aim to review the outcomes from previous investigations to further emphasize the effect of nursing workload on ICU patient outcomes and safety.

The effect of bed-to-nurse ratio on hospital mortality of critically ill children on mechanical ventilation: a nationwide population-based study

BACKGROUND

Despite the high workload of mechanical ventilation, there has been a lack of studies on the association between nurse workforce and mortality in mechanically ventilated patients. We evaluated the association of the bed-to-nurse ratio with mortality in ventilated pediatric patients admitted to an intensive care unit (ICU).

METHODS

We conducted a nationwide retrospective analysis by using the Korean National Health Insurance database, which categorizes the bed-to-nurse ratio into 9 grades according to the number of beds divided by the number of full-time equivalent registered nurses in a unit. Patients of ages between 28 days and 18 years were enrolled. Multiple admissions and transfers from other hospitals were excluded. We evaluated the odds ratios (ORs) of in-hospital mortality using 4 groups (Grade 1: bed-to-nurse < 0.50, Grade 2: < 0.63, Grade 3: < 0.77, Grade 4 or above > 0.77) with adjustment of patient factors, hospital factors, and treatment requirements.

RESULTS

Of the 27,849 patients admitted to ICU, 11,628 (41.8%) were on mechanical ventilation. The overall in-hospital mortality rates in Grade 1, Grade 2, Grade 3, and Grade 4 or above group were 4.5%, 6.8%, 6.9%, and 4.7%, respectively. The adjusted ORs (95% CI) for in-hospital mortality of mechanically ventilated patients in the Grade 2, Grade 3, and Grade 4 or above compared to those in Grade 1 were 2.73 (95% CI 1.51-4.95), 4.02 (95% CI 2.23-7.26), and 7.83 (4.07-15.07), respectively. However, for patients without mechanical ventilation, the adjusted ORs of in-hospital mortality were not statistically significant.

CONCLUSION

In mechanically ventilated patients, the adjusted mortality rate increased significantly, as the bed-to-nurse ratio of the ICU increased. Policies that limit the number of ventilated patients per nurse should be considered. Trial registration retrospectively registered.

Predicting Sustainable Employability in Swedish Healthcare: The Complexity of Social Job Resources

Achieving sustainable employability (SE), i.e., when employees are able to continue working in a productive, satisfactory, and healthy manner, is a timely challenge for healthcare. Because healthcare is a female-dominated sector, our paper investigated the role of social job resources in promoting SE. To better illustrate the complexity of the organizational environment, we incorporated resources that operate at different levels (individual, group) and in different planes (horizontal, vertical): trust (individual-vertical), teamwork (group-horizontal), and transformational leadership (group-vertical). Based on the job demands-resources model, we predicted that these resources initiate the motivational process and thus promote SE. To test these predictions, we conducted a 3-wave study in 42 units of a healthcare organization in Sweden. The final study sample consisted of 269 professionals. The results of the multilevel analyses demonstrated that, at the individual level, vertical trust was positively related to all three facets of SE. Next, at the group level, teamwork had a positive link with employee health and productivity, while transformational leadership was negatively related to productivity. These findings underline the importance of acknowledging the levels and planes at which social job resources operate to more accurately capture the complexity of organizational phenomena and to design interventions that target the right level of the environment.

Are high nurse workload/staffing ratios associated with decreased survival in critically ill patients? A cohort study

Background

Despite the central role of nurses in intensive care, a relationship between intensive care nurse workload/staffing ratios and survival has not been clearly established. We determined whether there is a threshold workload/staffing ratio above which the probability of hospital survival is reduced and then modeled the relationship between exposure to inadequate staffing at any stage of a patient’s ICU stay and risk-adjusted hospital survival.

Methods

Retrospective analysis of prospectively collected data from a cohort of adult patients admitted to two multi-disciplinary Intensive Care Units was performed. The nursing workload [measured using the Therapeutic Intervention Scoring System (TISS-76)] for all patients in the ICU during each day to average number of bedside nurses per shift on that day (workload/nurse) ratio, severity of illness (using Acute Physiology and Chronic Health Evaluation III) and hospital survival were analysed using net-benefit regression methodology and logistic regression.

Results

A total of 894 separate admissions, representing 845 patients, were analysed. Our analysis shows that there was a 95% probability that survival to hospital discharge was more likely to occur when the maximum workload-to-nurse ratio was <40 and a more than 95% chance that death was more likely to occur when the ratio was >52. Patients exposed to a high workload/nurse ratio (≥52) for ≥1 day during their ICU stay had lower risk-adjusted odds of survival to hospital discharge compared to patients never exposed to a high ratio (odds ratio 0.35, 95% CI 0.16–0.79).

Conclusions

Exposing critically ill patients to high workload/staffing ratios is associated with a substantial reduction in the odds of survival.

The right team at the right time - Multidisciplinary approach to multi-trauma patient with orthopedic injuries

Integrated, multidisciplinary team approach to the multiply injured patient can help optimize care, minimize morbidity, and reduce mortality. It also provides a framework for accelerated postinjury rehabilitation course. The characteristics and potential benefits of this approach, including team dynamics and interactions, are discussed in this brief review. Emphasis is placed on synergies provided by specialty teams working together in the framework of care coordination, timing of surgical and nonsurgical interventions, and injury/physiologic considerations.

A Cross-sectional Overview of the First 4,000 Incidents Reported to webAIRS, a De-identified Web-based Anaesthesia Incident Reporting System in Australia and New Zealand

webAIRS is a web-based de-identified anaesthesia incident reporting system, which was introduced in Australia and New Zealand in September 2009. By July 2016, 4,000 incident reports had been received. The incidents covered a wide range of patient age (<28 days to >90 years), American Society of Anesthesiologists physical status, and body mass index (<18.5 to >50 kg/m2). They occurred across a wide range of anaesthesia techniques and grade of anaesthesia provider, and over a wide range of anaesthetising locations and times of day. In a high proportion the outcome was not benign; about 26% of incidents were associated with patient harm and a further 4% with death. Incidents appeared to be an ever-present risk in anaesthetic practice, with extrapolated estimates exceeding 200 per week across Australia and New Zealand. Independent of outcomes, many anaesthesia incidents were associated with increased use of health resources. The four most common main categories of incident were Respiratory/Airway, Medication, Cardiovascular, and Medical Device/Equipment. Over 50% of incidents were considered preventable. The narratives accompanying each incident provide a rich source of information, which will be analysed in subsequent reports on particular incident types. The summary data in this initial overview are a sober reminder of the prevalence and unpredictability of anaesthesia incidents, and their potential morbidity and mortality. The data justify current efforts to better prevent and manage anaesthesia incidents in Australia and New Zealand, and identify areas in which increased resources or additional initiatives may be required.

Evaluation of Mental Workload among ICU Ward's Nurses

Background: High level of workload has been identified among stressors of nurses in intensive care units (ICUs). The present study investigated nursing workload and identified its influencing perfor­mance obstacles in ICUs.

Methods: This cross-sectional study was conducted, in 2013, on 81 nurses working in ICUs in Imam Khomeini Hospital in Tehran, Iran. NASA-TLX was applied for assessment of workload. Moreover, ICUs Performance Obstacles Questionnaire was used to identify performance obstacles associated with ICU nursing.

Results: Physical demand (mean=84.17) was perceived as the most important dimensions of workload by nurses. The most critical performance obstacles affecting workload included: difficulty in finding a place to sit down, hectic workplace, disorganized workplace, poor-conditioned equipment, waiting for using a piece of equipment, spending much time seeking for supplies in the central stock, poor quality of medical materials, delay in getting medications, unpredicted problems, disorganized central stock, outpatient surgery, spending much time dealing with family needs, late, inadequate, and useless help from nurse assistants, and ineffective morning rounds (P-value<0.05).

Conclusion: Various performance obstacles are correlated with nurses' workload, affirms the significance of nursing work system characteristics. Interventions are recommended based on the results of this study in the work settings of nurses in ICUs.

Validation of the Chinese version of the Quality of Nursing Work Life scale

Quality of Nursing Work Life (QNWL) serves as a predictor of a nurse's intent to leave and hospital nurse turnover. However, QNWL measurement tools that have been validated for use in China are lacking. The present study evaluated the construct validity of the QNWL scale in China. A cross-sectional study was conducted conveniently from June 2012 to January 2013 at five hospitals in Guangzhou, which employ 1938 nurses. The participants were asked to complete the QNWL scale and the World Health Organization Quality of Life abbreviated version (WHOQOL-BREF). A total of 1922 nurses provided the final data used for analyses. Sixty-five nurses from the first investigated division were re-measured two weeks later to assess the test-retest reliability of the scale. The internal consistency reliability of the QNWL scale was assessed using Cronbach's α. Test-retest reliability was assessed using the intra-class correlation coefficient (ICC). Criterion-relation validity was assessed using the correlation of the total scores of the QNWL and the WHOQOL-BREF. Construct validity was assessed with the following indices: χ2 statistics and degrees of freedom; relative mean square error of approximation (RMSEA); the Akaike information criterion (AIC); the consistent Akaike information criterion (CAIC); the goodness-of-fit index (GFI); the adjusted goodness of fit index; and the comparative fit index (CFI). The findings demonstrated high internal consistency (Cronbach's α = 0.912) and test-retest reliability (interclass correlation coefficient = 0.74) for the QNWL scale. The chi-square test (χ2 = 13879.60, df [degree of freedom] = 813 P = 0.0001) was significant. The RMSEA value was 0.091, and AIC = 1806.00, CAIC = 7730.69, CFI = 0.93, and GFI = 0.74. The correlation coefficient between the QNWL total scores and the WHOQOL-BREF total scores was 0.605 (p<0.01). The QNWL scale was reliable and valid in Chinese-speaking nurses and could be used as a clinical and research instrument for measuring work-related factors among nurses in China.

Cognitive and system factors contributing to diagnostic errors in radiology

OBJECTIVE

In this article, we describe some of the cognitive and system-based sources of detection and interpretation errors in diagnostic radiology and discuss potential approaches to help reduce misdiagnoses.

CONCLUSION

Every radiologist worries about missing a diagnosis or giving a false-positive reading. The retrospective error rate among radiologic examinations is approximately 30%, with real-time errors in daily radiology practice averaging 3-5%. Nearly 75% of all medical malpractice claims against radiologists are related to diagnostic errors. As medical reimbursement trends downward, radiologists attempt to compensate by undertaking additional responsibilities to increase productivity. The increased workload, rising quality expectations, cognitive biases, and poor system factors all contribute to diagnostic errors in radiology. Diagnostic errors are underrecognized and underappreciated in radiology practice. This is due to the inability to obtain reliable national estimates of the impact, the difficulty in evaluating effectiveness of potential interventions, and the poor response to systemwide solutions. Most of our clinical work is executed through type 1 processes to minimize cost, anxiety, and delay; however, type 1 processes are also vulnerable to errors. Instead of trying to completely eliminate cognitive shortcuts that serve us well most of the time, becoming aware of common biases and using metacognitive strategies to mitigate the effects have the potential to create sustainable improvement in diagnostic errors.

Validation of standard times and influencing factors during the development of the Workload Indicator for Nursing

BACKGROUND

A tool to assist in optimal allocation of available nursing resources is of paramount importance.

AIMS

The goals of this study were as follows: (1) to determine whether the standard time values of the Belgian Nursing Minimum Dataset are a valid basis for the development of a Workload Indicator for Nursing; (2) to quantify the impact of factors that most influence nursing workload; and (3) to examine the cross-impact of items of the Belgian Nursing Minimum Dataset.

DESIGN

This research project is a prospective observational study with exploratory aspects.

METHODS

The data for this prospective study were collected during September 2010 from a convenience sample of 23 nursing units in four hospitals in Belgium. The data collection included three parts: (1) the registration of the items of the Belgian Nursing Minimum Dataset; (2) the amount of time committed to direct patient care; and (3) analysis of variables, which influence the nursing workload at patient and unit level.

RESULTS

The correlation coefficients for the sum of Direct and Indirect Patient Care and the Workload Indicator for Nursing-score of the surgical, internal medicine and intensive care units were 0·85, 0·88 and 0·89 respectively. Significant differences in standard time utilization for nursing activities at the patient level are directly related to the level of mobility assistance required. Units needing significantly more time for Direct and Indirect Patient Care than predicted by the Workload Indicator for Nursing-score had a higher mean number of complex nursing activities per patient.

CONCLUSIONS

The high correlation coefficients between the total time utilized for direct patient care and the WiN-score indicate that the standard time values of the Belgian Nursing Minimum Dataset are valid.

Do we need a national incident reporting system for medical imaging?

The essential role of an incident reporting system as a tool to improve safety and reliability has been described in high-risk industries such as aviation and nuclear power, with anesthesia being the first medical specialty to successfully integrate incident reporting into a comprehensive quality improvement strategy. Establishing an incident reporting system for medical imaging that effectively captures system errors and drives improvement in the delivery of imaging services is a key component of developing and evaluating national quality improvement initiatives in radiology. Such a national incident reporting system would be most effective if implemented as one piece of a comprehensive quality improvement strategy designed to enhance knowledge about safety, identify and learn from errors, raise standards and expectations for improvement, and create safer systems through implementation of safe practices. The potential benefits of a national incident reporting system for medical imaging include reduced morbidity and mortality, improved patient and referring physician satisfaction, reduced health care expenses and medical liability costs, and improved radiologist satisfaction. The purposes of this article are to highlight the positive impact of external reporting systems, discuss how similar advancements in quality and safety can be achieved with an incident reporting system for medical imaging in the United States, and describe current efforts within the imaging community toward achieving this goal.

Knowledge is power: studying critical incidents in intensive care

Despite their difficult definition and taxonomy, it is imperative to study critical incidents in intensive care, since they may be followed by adverse events and compromised patient safety. Identifying recurring patterns and factors contributing to critical incidents constitutes a prerequisite for developing effective preventive strategies. Self-reporting methodology, although widely used for studying critical incidents, has been criticized in terms of reliability and may considerably underestimate both overall frequency and specific types of them. Promotion of non-blaming culture, analysis of critical incident reports and development of clinical recommendations are expected to minimize critical incidents in the future.

[Usefulness of failure mode and effects analysis to improve patient safety during the process of incorporating new nurses in an intensive care unit]

OBJECTIVE

To analyze proactively the process of incorporating new nurses in the intensive care unit (ICU) in order to detect risk areas and establish improvements that increase critical patient safety.

MATERIAL AND METHODS

Once the risk area was defined, the different phases of failure mode and effects analysis (FMEA) were applied: work team selection; process design; process phases definition; failure modes, possible causes and effects analysis; risk priority for each failure, and development of ameliorating and corrective actions. The proposed actions consisted of an orientation and training program (theoretical and practical) for new nurses, a supervision plan, a progressive responsibility program and ICU participation in personnel recruitment.

RESULTS

Twelve nurses began to work in the ICU during the first 18 months of the program's implementation. Of these, only one nurse had full experience in critical care and three had partial experience. Participation of the ICU in personnel recruitment was nil. All the nurses with no or partial experience followed the orientation program (nursing supervisor interview, test of previous knowledge, handing over of the employee handbook, etc.), the theoretical and practical training program (supervision and tutorship) and the progressive responsibility program. More than half (63.6%) of the new nurses had another nurse duplicating their jobs during the training period and 54.5% of the new nurses attended the critical care course for nurses. Nurses participating in the orientation and training program expressed a high level of satisfaction. These measures helped nurses to decrease their stress and anxiety, increase and consolidate their knowledge, and provide safer care to critical patients.

CONCLUSIONS

FMEA is a useful tool for improving ICU processes, even those involving human resources. The improvements implemented to decrease clinical risk related to the incorporation of new nurses in the ICU, based on previous training, will increase the safety of critical patient care by decreasing human errors due to inexperience.

Pattern of psychiatric inpatient admission in ibadan: implications for service organisation and planning

Introduction:

Reports from different parts of the world has shown a seasonal pattern in psychiatric admission. Seasonal changes in climatic and social situations have been attributed. Such audit of psychiatric services is not a popular research venture in Nigeria.

Objectives:

The study aims to describe the pattern of old psychiatric admissions in a tertiary health facility and the socio-cultural and environmental factors that may influence the pattern.

Methods:

Data on monthly admissions over a 5-year period were extracted from the admission and discharge records kept by the nursing services unit. The data was processed using Microsoft excel and the pattern over the 5-year period was examined using graphical representations.

Results:

There were 2140 admissions during the review period, comprising 1138 ( 53.2%) females and 1002 males. The mean new admission per month was 34.55 (M:16.7, F:18.96) with a standard deviation of 7.49 for all admissions. There was a seasonal pattern in admission. Some socio-cultural and environmental factors that may explain the pattern were examined.

Conclusion:

This study suggests a seasonal pattern of psychiatric admission in a tertiary health facility in Ibadan. Recommendations were made on how to make use of the knowledge of the seasonal pattern of admission to mitigate disruptions in workload that may be occasioned by the observed pattern.

Perceived adverse patient outcomes correlated to nurses' workload in medical and surgical wards of selected hospitals in Kuwait

AIM

This study was carried out to identify the perceived adverse patient outcomes as related to nurses' workload. It also assessed nurses' perception of variables contributing to the workload and adverse patient outcomes.

BACKGROUND

Several studies have been published on adverse patient outcomes in which a correlation was found between nurses' workload and some adverse patient outcomes.

DESIGN

A cross-sectional survey was conducted between registered nurses (n = 780) working in medical and surgical wards of five general governmental hospitals in Kuwait. DATA COLLECTION INSTRUMENTS: Data were collected using a self-administered questionnaire consisting of three sections to elicit information about the sample characteristics, perception of workload and perceived adverse patient outcomes during the last shift and last working week.

RESULTS

The three major perceived adverse outcomes reported by the nurses while on duty during their last shift were: complaints from patients and families (2%), patients received a late dose or missed a dose of medication (1.8%) and occurrences of pressure ulcer (1.5%). Similarly, the reported adverse outcomes over the past week were complaints from patients and families (5%), patients received a late dose or missed a dose of medication (5.3%) and discovery of a urinary tract infection (3.7%). Increases in nurse-patient load, bed occupancy rate, unstable patients' condition, extra ordinary life support efforts and non-nursing tasks; all correlated positively with perceived adverse patient outcomes.

CONCLUSION

This study sheds light on an important issue affecting patient safety and quality of care as perceived by the nurses themselves as caregivers.

RELEVANCE TO CLINICAL PRACTICE

Nurses' perception of variables contributing to adverse patient outcomes and their workload could significantly affect the provided nursing care and nursing care recipients. The findings could help in policy formulation and planning strategies to decrease adverse patient outcomes in many countries with a health care structure similar to that of Kuwait.

The difficult airway in adult critical care

INTRODUCTION

The difficult airway is a common problem in adult critical care patients. However, the challenge is not just the establishment of a safe airway, but also maintaining that safety over days, weeks, or longer.

AIMS

This review considers the management of the difficult airway in the adult critical care environment. Central themes are the recognition of the potentially difficult airway and the necessary preparation for (and management of) difficult intubation and extubation. Problems associated with tracheostomy tubes and tube displacement are also discussed.

RESULTS

All patients in critical care should initially be viewed as having a potentially difficult airway. They also have less physiological reserve than patients undergoing airway interventions in association with elective surgery. Making the critical care environment as conducive to difficult airway management as the operating room requires planning and teamwork. Extubation of the difficult airway should always be viewed as a potentially difficult reintubation. Tube displacement or obstruction should be strongly suspected in situations of new-onset difficult ventilation.

CONCLUSIONS

Critical care physicians are presented with a significant number of difficult airway problems both during the insertion and removal of the airway. Critical care physicians need to be familiar with the difficult airway algorithms and have skill with relevant airway adjuncts.

Clinical review: medication errors in critical care

Medication errors in critical care are frequent, serious, and predictable. Critically ill patients are prescribed twice as many medications as patients outside of the intensive care unit (ICU) and nearly all will suffer a potentially life-threatening error at some point during their stay. The aim of this article is to provide a basic review of medication errors in the ICU, identify risk factors for medication errors, and suggest strategies to prevent errors and manage their consequences.

Patient severity as an indicator of nursing workload in the intensive care unit

The importance of measuring nursing workload in the intensive care unit (ICU) has been supported by both an increasing demand for nursing personnel and the relationship of nursing workload with patient safety. According to previous studies, the correlation between clinical severity of ICU patients and nursing workload measured by Therapeutic Intervention Scoring System has been estimated to be particularly high. The aim of this study was to investigate whether clinical severity of ICU patients can be used for the prediction of nursing workload on a daily basis. All patients admitted in the ICU of the General University Hospital of Patras for a 5-month period were enrolled in the study. Projet de Recherche en Nursing (PRN) Réa and Acute Physiology and Chronic Health Evaluation (APACHE) II scores of patients were calculated, the first on a daily basis and the second on the day of admission. Simple linear regression was used for statistical analysis of data. One hundred thirty-eight patients were studied. A progressive increase in mean daily PRN Réa of patients all along the amplitude of APACHE II values was shown. APACHE II could predict 25.6% (p < 0.01) of the daily variability of PRN Réa of patients. Regarding categories of PRN Réa, respiration, communication, diagnostic methods and treatments were significantly predicted by APACHE II. APACHE II explained higher proportions of PRN Réa in medical male patients aged >60 years. Clinical severity of the ICU patients measured by APACHE II is an important early indicator of daily nursing workload, especially of care demands associated with respiration, diagnostic methods and treatments.

Workload and patient safety among critical care nurses

Several dimensions of workload experienced by nurses working in ICUs are described in this article, including the physical workload related to patient handling. The effects of workload on various outcomes, such as the health, safety, and quality of working life of nurses, and the safety of care provided by ICU nurses are discussed. A systemic approach to the assessment of workload is proposed that is aimed at identifying the work system factors that contribute to the different facets of workload and the interdependencies among the various dimensions of workload.

Effect of fatigue, workload, and environment on patient safety in the pediatric intensive care unit

INTRODUCTION

Pediatric intensive care unit patient care occurs in an unpredictable, technology-rich environment that is dependent on highly skilled providers who need constant communication-all features providing the setting for potential error. This review examines basic principles of human error and sleep physiology and evaluates the evidence for potential effects of fatigued healthcare workers and workload on medical error. BODY: The pediatric intensive care unit setting, examined from a human factors engineering standpoint, is a highly complex environment in which fatigue and excessive workload can provide potential "holes" that may allow errors to occur. A large body of evidence is examined that suggests sleep deprivation can impair medical and surgical performance and can be improved with scheduling intervention. Nursing fatigue and workload have documented effects on increasing intensive care unit error, infections, and cost. Specific environmental factors such as distractions and communication barriers are also associated with greater error.

CONCLUSION

Fatigue, excessive workload, and the pediatric intensive care unit environment can adversely affect the performance of physicians and nurses working in the pediatric intensive care unit. The weight of the evidence suggests that these factors have the potential to contribute to medical error in the pediatric intensive care unit.

[Adverse events in Intensive Medicine. Managing risk]

Health care interventions entail a risk of adverse events (AE), that may cause lesions, incapacities and even death in the patients. Given the complexity of the care of the critical patient, the Critical Care Services are a high risk setting for the appearance of AE in these patients, many of them avoidable. Several studies show the influence of organizational factors focused on the system in the reduction of care risk and on the result of the critical patients. The voluntary and anonymous registry and reporting systems make it possible to identify a significant percentage of these incidents, analyze the factors related (that contribute or limit), establish preventive strategies, permitting management of risk, and potentially reduce the appearance and consequences of avoidable AE with all this. Initiatives such as the ICU Safety Reporting System (ICUSRS), that use a web database as registry system and includes contributions from different sites, favor the safety and risk culture, essential in the improvement of health quality of critical patients.

Consensus forum: worldwide guidelines on the critical care nursing workforce and education standards

This article explores the key themes, evidence, and arguments that inform the current position statements. It is acknowledged that future research, evidence, and practice experience may create the need to review and change these guidelines. Reform and refinement of the guidelines are inevitable; however, the current guidelines represent the best attempt yet to reach international consensus on what are appropriate standards to guide critical care nursing education and workforce requirements.

Evaluation of a nurse consultant's clinical activities and the search for patient outcomes in critical care

AIMS

To describe the actual clinical activities undertaken by a critical care nurse consultant in an eight-bedded adult surgical high dependency unit within a large NHS Teaching Hospitals NHS Trust.

BACKGROUND

In the United Kingdom, the first critical care nurse consultants were approved in 2000 following the Department of Health's (1999) revised career structure for nurses. Expert practice is a core function of the role although the nature of expert practice in the context of critical care is unclear. Expert practice is often deemed to be a feature of advanced practice and although a number of studies have investigated this in context of critical care, there is little insight into the nature of advanced practitioners' clinical practice and how it might influence patient outcome.

DESIGN METHODS

A diary was used by a critical care nurse consultant to record activity during scheduled clinical sessions. Data were collected for four months: 39 sessions were evaluated. Qualitative data were content analysed and coded into categories. Clinical activities were coded, categorized and analysed using SPSS 11.0 for windows (SPSS Inc., Chicago, IL, USA).

FINDINGS

Clinical activities included direct care activities, clinical leadership, education and training. Two main themes emerged from the qualitative data and were categorized as clinical reasoning and clinical instruction. Clinical activities arising from clinical reasoning and clinical instruction were aimed at minimizing risk and the provision of quality care. In doing this, one of the outcomes was the detection and resolution of untoward clinical occurrences.

CONCLUSION

The level of achievement--or end point--of clinical activities was that the patient was established in 'a state free from risk or harm that optimises rehabilitation'. 'A state free from risk or harm that optimizes rehabilitation' might be one outcome reflecting the needs of individual critically ill patients that is sensitive to individual nursing contribution.

RELEVANCE TO CLINICAL PRACTICE

There is increasing pressure on health-care professionals to identify and measure their individual impact on the outcome of patients. This study adds further insight into the complexities associated with evaluating the influence of individual contribution on patient outcome, especially when it is characterized by complex processes involving clinical judgement and decision-making.

Characteristics and outcome of unplanned extubation in ventilated preterm and term newborns on a neonatal intensive care unit

BACKGROUND

Unplanned extubation events (UEE) are a serious hazard to patient safety, especially on a neonatal intensive care unit (NICU), where reestablishing a secure airway can be difficult. The following study was undertaken to analyze characteristics of UEE and develop prevention strategies.

METHODS

A retrospective cohort study on a level III single center NICU was undertaken. Patient records of a 12-month period from December 2003 to December 2004 were analyzed using a standardized evaluation form. Fischer's exact t-test and the Mann-Whitney U-Ranked Sum test were used for statistical analysis.

RESULTS

One hundred and four neonates with a total ventilation time of 14 495 h were included in this study. Of these patients 12 UEE were observed (1 UEE/1208 h of ventilation time). Neither median birth weight [1445 g (range 460-4650) vs 1755 g (range 460-3570 g)] nor median gestational age [31.5 weeks (range 25.6-39.6 weeks) vs 32.7 weeks (range 23.9-41.5 weeks)] differed significantly between neonates with UEE compared with the total group. When the UEE occurred, the neonates were cared for by experienced nursing staff with a median of 10 years nursing experience. The workload for the individual nurse was high: during shifts when UEE happened, each nurse had to take care of 3.85 patients (range 1.8-5 patients). This workload was higher than the average of 3 (range 1.6-6) patients/nurse during the study period. The most frequently reported reason for UEE was difficult fixation of the tracheal tube (TT) (four patients), followed by handling of the infant by nursing staff or physiotherapy (two patients) or an active infant in whom dislocation of the TT occurred without external manipulations (three patients). In three instances, the reason for the UEE was not documented. Of the 12 UEE observed in 10 patients, three required immediate reintubation, five were managed with nasal continuous positive airway pressure and four did not require further respiratory support. Of those who required support, FiO(2) increased by 14% over baseline compared with the FiO(2) prior to UEE.

CONCLUSIONS

Inadequate TT fixation could be identified as the main contributor to UEE and should be targeted in prevention strategies. The reintubation rate after UEE was only 25%. Overall, UEE did not result in an adverse outcome in terms of mortality. Length of stay on NICU was significantly longer in UEE patients.

Matching nurse skill with patient acuity in the intensive care units: a risk management mandate

AIM

This paper aims to highlight the need for the traditional concept of nursing skill mix to be reconfigured within a new concept of skill matching.

BACKGROUND

Substantive literature describes staff deployment and patient-dependency models. However, limited information exists as to what informs decision making regarding nurse skill assessment and subsequent patient allocation in intensive care units.

KEY ISSUES

In intensive care units, nurse numbers, available nursing skills and patient allocation decisions, impact directly on care provision and outcomes. This paper argues that staffing decisions that are based on insufficient knowledge which lack consideration of all pertinent factors result in poor 'skill matching', potential adverse events and poor outcomes. A critical inextricable link exists between staffing decisions, patient safety and risk in the intensive care unit. Use of a multifactorial skill-matching approach within a dedicated staffing decision-support system is recommended.

CONCLUSION

This commentary paper adds a new perspective to nurse-staffing decision practices and their relationship to risk management in the intensive care unit and offers a new research direction.

Nurse staffing levels and hospital mortality in critical care settings: literature review and meta-analysis

AIM

This paper reports a review of the literature on the association between critical care nurse staffing levels and patient mortality.

BACKGROUND

Statistically significant inverse associations between levels of nurse staffing and hospital mortality have not been consistently found in the literature. Critical care settings are ideal to address this relationship due to high patient acuity and mortality, high intensity of the nursing care required, and availability of individual risk adjustment methods.

METHODS

Major electronic databases were searched, including MEDLINE, EMBASE, and the Cumulative Index of Nursing and Allied Health Literature. The search terms included critical/intensive care, quality of health care, mortality/hospital mortality, personnel staffing and scheduling, and nursing staff (hospital). Only papers published in English were included. The original search was conducted in 2002 and updated in 2005.

RESULTS

Nine studies were selected from 251 references screened. All nine were observational. Six were conducted in the United States of America, one in Austria, one in Brazil, and one in Scotland. The unadjusted risk ratio of nurse staffing (high vs. low) on hospital mortality were combined meta-analytically (five studies). The pooled estimate was 0.65 (95% confidence interval 0.47-0.91). However, after adjusting for various covariates within each study, the individually reported associations between high nurse staffing and low hospital mortality became non-significant in all but one study.

CONCLUSION

The impact of nurse staffing levels on patients' hospital mortality in critical care settings was not evident in the reviewed studies. Methodological challenges that might have impeded correct assessment of the association include measurement problems in exposure status and confounding factors, often uncontrolled. The lack of association also indicates that hospital mortality may not be sensitive enough to detect the consequences of low nurse staffing levels in critical care settings.

Work environment and workforce problems: A cross-sectional questionnaire survey of hospital nurses in Belgium

OBJECTIVES

This study investigated Belgian hospital nurses' perceptions on work environment and workforce issues, quality of care, job satisfaction and professional decision making.

METHODS

All eligible nurses in a selection of 22 hospitals received the BELIMAGE questionnaire for a total of 13,958 potential respondents. Of these, 9941 returned study materials (response rate=71.2%) of which 9638 were valid and useable for statistical analysis (valid response rate=69.1%).

RESULTS

The study identified several areas of tension in the nursing profession. The commitment to being competent providers of quality care was remarkably strong among the nurses, but they also perceived the barriers in the work environment to be multiple and complex. Concerns about the quality of leadership and management, insufficient staff, time demands and stressful work environment are experienced as obstacles in providing good nursing care. Four out of ten nurses (39.2%) would not choose nursing again as a career and more than half of the nurses (54.3%) have contemplated leaving the profession at some point in time.

CONCLUSIONS

To effectively tackle the professional and workforce issues in nursing, investments should focus on redesigning a work environment that supports nurses in providing comprehensive professional care.

Safety, effectiveness and costs of different models of organising care for critically ill patients: literature review

New ways of working in critical care are emerging in response to increasing demands for care in the context of a limited critical care workforce. This review appraised the comparative safety, effectiveness and costs of new ways of working in critical care. All papers published in peer reviewed journals during 1990-2003 were utilised. A total of 933 potentially relevant papers were identified. Secondary sources including policy papers, and experts within the field were also used to inform this work. Initially 113 papers met the inclusion criteria. However, 58 of these described policy and secular trends in critical care and were therefore used only to provide background information. A total of 55 papers were then critically reviewed to provide academic focus on the subject area. Examples of comparative empirical research on new ways of working were limited, but the review revealed research activity in the areas of: impact of workload; nursing, medical and organisational factors affecting patient outcomes; and methods to support workforce calculations. The findings suggest that research into longer-term patient outcomes is needed together with a proactive and strategic interdisciplinary approach to practice, policy and research.

The professional self-image of nurses in Belgian hospitals: A cross-sectional questionnaire survey

This paper reports data on the professional self-image of 9638 nurses employed in 22 Belgian general hospitals with the goal of identifying problems affecting recruitment and retention. Nurses reported having a positive self-image. Most were proud to be a nurse and considered themselves competent health professionals having great responsibility. Although they reported that an ideal practice requires effective teamwork, supportive management, societal recognition, and sufficient time to perform their duties, they also felt that these essential conditions were absent in daily practice.

Review of the Australian incident monitoring system

BACKGROUND

A survey was conducted to assess the benefits and limitations of the Australian Incident Monitoring System (AIMS) as a programme to improve patient safety.

METHODS

A 12-point questionnaire was sent to 12 current users of AIMS in November 2002.

RESULTS

The AIMS provides a consistent system of coding, trending and monitoring of incident data. It promotes a patient safety culture and an awareness of system error. Other benefits include the building of teamwork and the implementation of strategies to reduce the prevalence and severity of incidents. The majority of respondents (83%) reported that AIMS investigations resulted in significant changes to equipment usage, medication prescribing or administration, clinical protocols, training programmes and falls risk assessment tools. Although 75% of users reported improvements in patient outcomes, these were difficult to measure. A major limitation of AIMS was the low rate of incident reporting by medical staff. Voluntary reporting systems did not capture all incident data and the information was often too generic for root cause analysis. There were difficulties benchmarking data and concerns were raised regarding the ownership of information. The programme requires ongoing resources to implement change strategies and to maintain incident reporting levels. On a scale of 1 (poor rating) to 10 (excellent rating) the mean benefit rating was 7.6.

CONCLUSION

The Australian Incident Monitoring System is beneficial as a component of a clinical risk management strategy. Usefulness could be improved by increased participation by medical staff. The level of resources required should not be underestimated if the programme is to demonstrate improvements to patient outcomes. More recent versions of AIMS promise improved capabilities and will require similar evaluation.

Staffing Effectiveness Evaluation

Staff development educators use many sources of information to conduct educational needs assessments to improve existing educational programs and to develop new ones. Staffing effectiveness evaluation information targets patient care and staffing outcomes. The overall objective of this article is to familiarize staff development educators with the staffing effectiveness evaluation process, events that have led to organizational efforts to measure it, Joint Commission on Accreditation of Healthcare Organizations' (JCAHO) expectations, methods for assessing variation and relationships of indicators, and implications for staff development educators.

A human factors engineering conceptual framework of nursing workload and patient safety in intensive care units

In this paper, we review the literature on nursing workload in intensive care units (ICUs) and its impact on patient safety and quality of working life of nurses. We then propose a conceptual framework of ICU nursing workload that defines causes, consequences and outcomes of workload. We identified four levels of nursing workload (ICU/unit level, job level, patient level, and situation level), and discuss measures associated with each of the four levels. A micro-level approach to ICU nursing workload at the situation level is proposed and recommended in order to reduce workload and mitigate its negative impact. Performance obstacles are conceptualized as causes of ICU nursing workload at the situation level.

Improving the ICU: part 2

ICUs are a vital but troubled component of modern health-care systems. Improving ICU performance requires that we shift from a paradigm that concentrates on individual performance, to a systems-oriented approach that emphasizes the need to assess and improve the ICU systems and processes that hinder the ability of individuals to perform their jobs well. This second part of a two-part treatise establishes a practical framework for performance improvement and examines specific strategies to improve ICU performance, including the use of information systems.

Reporting of unintended events in an intensive care unit: comparison between staff and observer

Background

In order to identify relevant targets for change, it is essential to know the reliability of incident staff reporting. The aim of this study is to compare the incidence and type of unintended events (UE) reported by facilitated Intensive Care Unit (ICU) staff with those recorded concurrently by an observer.

Methods

The study is a prospective data collection performed in two 4-bed multidisciplinary ICUs of a teaching hospital. The format of the UE reporting system was voluntary, facilitated and not necessarily anonymous, and used a structured form with a predetermined list of items. UEs were reported by ICU staff over a period of 4 weeks. The reporting incidence during the first fourteen days was compared with that during the second fourteen. During morning shifts in the second fourteen days, one observer in each ICU recorded any UE seen. The staff was not aware of the observers' study. The incidence of UEs reported by staff was compared with that recorded by the observers.

Results

The staff reported 36 UEs in the first fourteen days and 31 in the second.. The incidence of UE detection during morning shifts was significantly higher than during afternoon or night shifts (p < 0.001). Considering only working day morning shifts, the rate of UE reporting by the staff per 100 patient days was 26.9 (CI 95% 16.9–37.0) in the first fourteen day period and 20.3 (CI 95% 10.3–30.4) in the second. The rate of UE detection by the observers was 53.1 per 100 patient days (CI 95% 40.6–65.6), significantly higher (p < 0.001) than that reported concurrently by the staff. There was excellent agreement between staff and observers about the severity of the UEs recorded (Intraclass Correlation Coefficient 0.869). The observers recorded mainly UEs involving Airway/mechanical ventilation and Patient management, and the staff Catheter/Drain/Probe and Medication errors (p = 0.025).

Conclusion

UE incidence is strongly underreported by staff in comparison with observers. Also the types of UEs reported are different. Invaluable information about incidents in ICU can be obtained in a few days by observer monitoring.

Nurse staffing and unplanned extubation in the pediatric intensive care unit

OBJECTIVE

To determine the association between unplanned extubations and years of nurse experience and nurse-to-patient ratio in the pediatric intensive care unit (PICU).

DESIGN

Case-control study.

SETTING

University-affiliated children's hospital PICU.

PATIENTS

Unplanned extubations were identified from January 1999 through December 2002. Three control patients for each of the patients experiencing an unplanned extubation were selected on three matching factors: age, intubation duration, and severity of illness as defined by the Pediatric Risk of Mortality (PRISM) III.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Fifty-five of 1,004 intubated patients (5.5%) experienced an unplanned extubation during the 4-yr period. A conditional logistic regression analysis was used to evaluate the association between a patient's risk of an unplanned extubation and the nurse's years of PICU experience and nurse-to-patient ratio. Factors associated with unplanned extubations included the documentation of patient agitation (odds ratio, 2.99; 95% confidence interval, 1.14, 7.86) and a nurse-to-patient ratio of 1:2 (one nurse caring for two patients) relative to a nurse-to-patient ratio of 1:1 (odds ratio, 4.24; 95% confidence interval, 1.00, 19.10). Years of PICU nursing experience, patient restraints, and the method of sedation delivery (continuous infusion vs. intermittent bolus) were not associated with unplanned extubations.

CONCLUSIONS

Pediatric patients are more likely to experience an unplanned extubation when being cared for by a nurse assigned to two patients compared with a nurse caring for one patient. To provide safe patient care, health care policymakers and hospital administrators should consider the nurse-to-patient ratio and its potential association with adverse events in hospitalized children.

A system factors analysis of airway events from the Intensive Care Unit Safety Reporting System (ICUSRS)*

OBJECTIVE

To evaluate the contributing and limiting factors for airway events reported in the Intensive Care Unit Safety Reporting System (ICUSRS) developed in partnership with the Society of Critical Care Medicine.

DESIGN

Analysis of system factors in airway vs. nonairway events reported to a voluntary, anonymous, Web-based patient safety reporting system (the ICUSRS).

SETTING

Sixteen adult and two pediatric intensive care units (ICU) across the United States.

PATIENTS

Incidents reported during the 12-month period ending June 30, 2003.

INTERVENTIONS

None

MEASUREMENTS

Descriptive characteristics of incidents (defined as events that could have, or did, cause harm), patients, and patient harm; separate multivariable logistic regression analyses of contributing and limiting factors for airway vs. nonairway events.

MAIN RESULTS

There were 78 airway and 763 nonairway events reported. More than half of airway events were considered preventable. One patient death was attributed to an airway event. Physical injury, increased hospital length of stay, and family dissatisfaction occurred in at least 20% of airway events. Important factors contributing to reported airway events (odds ratio (OR), 95% confidence interval (CI)) included patients' medical condition (5.24, 3.07-8.95) and age <1 yr old (4.15, 1.79-9.59). Factors limiting the impact of airway events (OR, 95% CI) included adequate ICU staffing (3.60, 1.71-7.56) and use of skilled assistants (3.20, 1.62-6.32).

CONCLUSIONS

Patients are harmed by unintended and preventable incidents involving airway management. Prevention efforts should focus on critically ill infants and patients with complex medical conditions. Managers should ensure appropriate ICU staffing to limit the impact of airway events when they occur.

The Hospital Mortality of Patients Admitted to the ICU on Weekends

STUDY OBJECTIVES

Previous studies have suggested that patients are more likely to die in the hospital if they are admitted on a weekend than on a weekday. This study was conducted to determine whether weekend admission to the ICU increases the risk of dying in the hospital.

DESIGN

Retrospective cohort study.

SETTING

ICU of a single tertiary care medical center.

PATIENTS

A total of 29,084 patients admitted to medical, surgical, and multispecialty ICUs from October 1994 through September 2002.

INTERVENTIONS

None.

MEASUREMENTS AND RESULTS

The weekend ICU admissions comprised 27.9% of all ICU admissions (8,108 ICU admissions). The overall hospital mortality rate was 8.2% (2,385 deaths). Weekend ICU admission was associated with a higher unadjusted hospital mortality rate than that for weekday ICU admission (11.3% vs 7.0%, respectively; odds ratio [OR], 1.70; 95% confidence interval [CI], 1.55 to 1.85). In multivariable analyses controlling for the factors associated with mortality such as APACHE (acute physiology and chronic health evaluation) III predicted mortality rate, ICU admission source, and intensity of treatment, no statistically significant difference in hospital mortality was found between weekend and weekday admissions in the overall study population (OR, 1.06; 95% CI, 0.95 to 1.17). For weekend ICU admissions, the observed hospital mortality rates of the medical, multispecialty, and surgical ICUs were 15.2%, 17.2%, and 6.4%, respectively, and for weekday ICU admissions the rates were 16.3%, 10.1%, and 3.5%, respectively. Subgroup analyses showed that weekend ICU admission was associated with higher adjusted hospital mortality rates than was weekday ICU admission in the surgical ICU (OR, 1.23; 95% CI, 1.03 to 1.48), but not in the medical or multispecialty ICUs.

CONCLUSIONS

The overall adjusted hospital mortality rate of patients admitted to the ICU on a weekend was not higher than that of patients admitted on a weekday. However, weekend ICU admission to the surgical ICU was associated with an increased hospital mortality rate.

Adverse events in acute care: an integrative literature review

An integrative literature review was conducted to investigate studies on adverse events reported in medical, health services, and nursing literature. The review was guided by the method proposed by Jackson (1980) and Ganong (1987). Three questions shaped the review: (a) What terms are used to denote adverse events? (b) What purposes drive adverse events research? and (c) What data sources are used to study adverse events? Adverse events was the dominant term, the study of adverse events as an outcome variable was the prevailing research purpose, and monitoring or screening the patient clinical record and self-reported incidents by health care professionals were the main data sources. Future research is recommended to conceptualize and study adverse events.
