Relationships between patient dependency, nursing workload and quality

The nature and value of dependency-acuity-quality (DAQ) demand-side nursing workforce planning methods are set in the context of nursing workforce planning and development. Extensive DAQ data from one of the largest UK nursing workforce studies (347 wards) involving 64 high-quality and 62 low-quality hospital wards, are reconsidered in a workload and quality context. Results generate new insights; for example, poor quality care is more likely to be a feature of larger wards with fluctuating workloads than smaller wards with consistently high workloads owing to inflexible nurse staffing. Nursing activity and staffing differences between high- and low-quality wards are highlighted. Recommendations are made to improve nursing management and practice as well as the next phase of DAQ studies.     

Measuring nursing workload in intensive care: an observational study using closed circuit video cameras

BACKGROUND: There is an increasing demand for intensive care provision in the United Kingdom (UK), partly because of a national shortage of intensive care beds. The problem is compounded by the current method for calculating the nurse: patient ratio using a Nurse Workload Patient Category scoring system or similar adaptations used in many intensive care units. This ratio is calculated by using patient category or dependency scales, which operate on the assumption that the more critically ill the patient, the more nurse time is needed to care for the patient. However, many mechanically ventilated critically ill patients (allocated a high category of care) may need less nursing care than patients who are self-ventilating and allocated a lower level of dependence. PURPOSE: In this study, a video recorder was used to document nurse activity for 48 continuous shifts in two intensive care units to determine the accuracy of the Nursing Workload Patient Category scoring system in measuring nurse workload. METHODS: The video data were correlated later with the Patient Category allocated to the patient by the nurse at the time. RESULTS: The results of this observational study demonstrated that, despite complex care needs, a high percentage of nursing activities observed in each unit consisted of low skill activity. Furthermore, nurses spent less time with patients categorized as in need of intensive care than those in need of high dependency care in both units. CONCLUSION: The findings suggest that existing nurse:patient ratio classifications may be inappropriate, since nurses spent less time with critically ill patients. Radical reconsideration of nursing levels and skill mix might make it possible to increase intensive care provision because fewer nurses would be needed to staff each bed. The findings support alternative and more flexible systems for assessing workload and the use of different nurse:patient ratios.     

Utilization of patient classification systems in Swedish hospitals and the degree of satisfaction among nursing staff

BACKGROUND: Although patient classification tools have been used in Sweden since the 1980s, few studies have examined how they are utilized and monitored. AIM: This paper investigates the patient classification systems implemented in hospitals in the country as well as the level of satisfaction of nurses with the implemented instrument. METHOD: A postal survey method was used in which a total of 128 questionnaires were sent to nurse managers. Twenty-three hospitals were identified with patient classification systems currently in operation. RESULTS AND CONCLUSION: The Zebra and Beakta systems are the most commonly used instruments. Nurse managers appear to be satisfied with the patient classification systems in use on their wards as a whole except for their inability to measure the quality of care provided, the time spent to use the instruments and the fact that the administration do not estimate nursing staff requirements using the system.     

Associations of nurse education level and nurse staffing with patient experiences of hospital care: A cross sectional study in China

Strengthening the nursing workforce is core to health system reform in China. Patient experiences of hospital care have been recognized as important in this endeavor. Studies exploring the relationships between nursing workforce and patient experiences of hospital care, however, are scarce. The aim of this cross-sectional study was to examine the associations between nurse education level, nurse staffing, and hospitalized patients’ experiences of hospital care. Participants were 1,582 nurses responsible for direct care and 1,305 hospitalized patients from 23 hospitals in Guangdong province, China in 2014. Education level of nurses was measured by the proportion of nurses holding a baccalaureate or higher degree. Nurse staffing was measured by the unit nurse-patient ratio. The Hospital Consumer Assessment of Health care Providers and Systems Scale was used to measure patient experiences of hospital care. Structural equation modeling demonstrated that a higher proportion of nurses holding a baccalaureate or higher degree was related directly to better patient perceptions of communication with nurses, responsiveness of nurses, pain management, and physical environment, and related indirectly to overall hospital ratings and recommendation of the hospital. A higher nurse-patient staffing ratio was associated directly with better patient perceptions of communication with nurses, education about new medications given in hospital, and physical environment, and indirectly with overall ratings and recommendation of the hospital. Our findings add new evidence in the Chinese societal context about the relationship between the nursing workforce and patient experiences of hospital care. Upgrading nurse education level and increasing nurse staffing could potentially improve patient experiences of hospital care.     

Nurse/patient dependency in community nursing

Patient/nurse dependency measures developed in the setting of acute hospital care were shown to be not wholly appropriate to community nursing. In a literature search undertaken to locate a tool suitable for measuring nurse/patient dependency in the community, a number of studies were found with material relevant to the subject. It appeared that age and mobility were determining factors in the allocation of district nursing time, but the complexity of other variables, including home conditions and the presence or absence of other carers, defied precise measurement. A functional assessment scale was found which had been developed for assessing and monitoring patients in the community and this might be utilised as a dependency measure if timings could be attached. A small pilot study undertaken in 1984/5 to investigate this possibility was followed by a larger study completed in 1987.     

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 and patient outcomes in inpatient rehabilitation settings.

In rehabilitation nursing, the patient classification systems or acuity models and nurse-staffing ratios are not supported by empirical evidence. Moreover there are no studies published characterizing nursing hours per patient day, proportion of RN staff and impact of agency nurses in inpatient rehabilitation settings. The purpose of this prospective observational study was to describe rehabilitation nurse staffing patterns, to validate the impact of rehabilitation nursing on patient outcomes, and to test whether existing patient measures on severity and outcomes in rehabilitation could be used as a proxy for burden of care to predict rehabilitation nurse staffing ceilings and daily nurse staffing requirements. A total of 54 rehabilitation facilities in the United States, stratified by geography, were randomly selected to participate in the study.     

"Realising the potential of critical care nurses": an exploratory study of the factors that affect and comprise the nursing contribution to the recovery of critically ill patients.

BACKGROUND: This study seeks to make evident the complexity of issues associated with the delivery of care by nurses to the critically ill. Emphasis had been placed on the results and implications of these for nursing practice. For a more in-depth account, the full report can be accessed on www.lscn.co.uk. METHOD: Following multi-centre research ethics committee approval, 10 critical care units participated in the 3-month study. Data collection comprised 231 nurse interviews and 51 relative interviews during 33 observation participation periods. RESULTS: Analysis demonstrated that the context of the critical care unit, in terms of geographical layout, unit activity, case mix and skill mix of nurses, had a major effect on the ability of nurses to contribute to the recovery of the critically ill. The effectiveness of the nursing resource appeared to be a function of knowledge (theoretical and patient related), experience and exposure. Nurses who were unused to a particular environment were not seen to be as effective as those who were. A model was constructed that identified the central tenets upon which nursing care can be optimised or compromised. When nursing care was optimised the difference nurses made potentially decreased risk to patients, enabled timely patient progression and increased the potential for patient recovery. CONCLUSIONS: The results confirm that nurses have a significant contribution to make in the recovery of patients who have experienced critical illness. Recommendations are far reaching and include the need to develop a valid and reliable tool which addresses patients' need for nursing in terms of nurses' knowledge and experience, patient dependency and decreasing clinical risk across the continuum of care. Current nursing workload tools and patient:nurse ratios were seen to lack validity because they do not appraise the context in which care is delivered, define all nurses as equal and concentrate on activity rather than the effect nurses can have on the outcome of the critically ill.     

Nursing workforce management: using benchmarking for planning and outcomes monitoring

The goal of maintaining the balance between demand for nursing care and the supply of nurses is the basis for state and regional planning to meet future nursing workforce needs. Projecting nursing supply needs solely on the basis of historical registered nurse to population ratios does not specifically consider the healthcare needs of the population. The authors present a model in which state population data and nursing resource data are compared with national data to assist state planning groups in developing an effective workforce management plan. Integrating population demographic data, healthcare needs of citizens, and nurse resource factors at the state level can improve the accuracy of projection statistics.     

Nurse/patient dependency — is it iatrogenic?

It is often assumed that nursing care is given in response to the patient's degree of incapacity. This study indicates that rather than nursing care arising as a response to patients' dependency, nursing care is producing dependency. A considerable proportion of the measured dependency of 168 elderly patients arose from the type of nursing care they received--it was iatrogenic. Task allocation nursing was found to be positively unhealthy for elderly long-stay patients, whilst individualized care (nursing process) was associated with lower patient dependency, a shorter hospital stay and a better chance of surviving the hospital stay. The findings demonstrate the inadequacy of nurse staffing formulas which are based on patient dependency. It is suggested that despite the rising numbers of very old people in the population, the elimination of nurse-induced dependency could reduce the level of dependency in geriatric wards.     

Northwick Park Care Needs Assessment: adaptation for inpatient neurological rehabilitation settings

AIM: This paper is a report of a study to establish which timings and assumptions of the Northwick Park Dependency Scale and Care Needs Assessment are appropriate to the inpatient rehabilitation setting and which, if any, require adjustment. BACKGROUND: Cost-effective provision of nursing care relies on being able to adjust staffing levels in accordance with patient dependency. The Northwick Park Dependency Scale and Care Needs Assessment enables direct assessment of nursing care needs in community settings. METHOD: An observational study was conducted in 2004 to record the time taken to complete direct nursing care interventions in a rehabilitation ward and to compare these times with simultaneously recorded time-estimates provided by the Care Needs Assessment. A total of 1168 nursing interactions were timed for 50 care episodes. RESULTS: There was considerable variation in the time taken for each nursing intervention, depending on overall patient dependency and the number of nurses required. Although there was good correlation between observed care times and those estimated by the Care Needs Assessment, observation confirmed that most interventions took substantially less time than the estimates. There was also a very different pattern of care in hospital compared with the community, with shorter, more frequent interactions as nurses distribute their time between different patients, and activities other than direct patient care. CONCLUSION: The Northwick Park Care Needs Assessment tool already has widespread application in other countries and its continued use for estimating community care needs remains relevant. The tool, once fully developed, will have the potential to contribute to international rehabilitation nursing workforce planning and research.     

Towards a comprehensive theory of nurse/patient empowerment: applying Kanter's empowerment theory to patient care

Towards a comprehensive theory of nurse/patient empowerment: applying Kanter's empowerment theory to patient care
Aim  The purpose of this theoretical paper is to propose an integrated model of nurse/patient empowerment that could be used as a guide for creating high-quality nursing practice work environments that ensure positive outcomes for both nurses and their patients.
Background  There are few integrated theoretical approaches to nurse and patient empowerment in the literature, although nurse empowerment is assumed to positively affect patient outcomes.
Evaluation  The constructs described in Kanter's (1993) work empowerment theory are conceptually consistent with the nursing care process and can be logically extended to nurses' interactions with their patients and the outcomes of nursing care.
Key issues  We propose a model of nurse/patient empowerment derived from Kanter's theory that suggests that empowering working conditions increase feelings of psychological empowerment in nurses, resulting in greater use of patient empowerment strategies by nurses, and, ultimately, greater patient empowerment and better health outcomes.
Conclusions  Empirical testing of the model is recommended prior to use of the model in clinical practice.
Implications for Nursing Management  We argue that empowered nurses are more likely to empower their patients, which results in better patient and system outcomes. Strategies for managers to empower nurses and for nurses to empower patients are suggested.     

Intensive care nursing requirements: resource allocation according to patient status.

Intensive care nursing allocation seemingly has been a negotiated solution to a never ending battle: an arbitrary nursing/patient ratio. To correct this deficit, a prospective study was proposed to quantitate the time duration of sufficient intensive care to match the severity of illness. A comprehensive list of all nursing actions was compiled and timed. Thereafter, frequencies were observed according to global classifications: serious, critical, or crisis. A simple classification system separates the hourly requirement: serious = 2:1 patient/nurse ratio, critical = 1.0:0.75 full time nursing, and crisis = 1.0:1.2 patient/nurse ratio (or single nurse requires assistance). The increased requirements are created by increased need for ICU skills: vital signs = 1 hour for serious patients, 4 hours for critical, and a maximum of 10 hours for crisis patients (90% crisis patients has pulmonary artery and arterial catheters). Other categories of increased nursing time reflect ventilatory support, increased number of continuous and intermittent medications, etc. Global assessment (serious, critical, or crisis patient status) can be quantitated in terms of nursing hours actually required. Objective, rational, and variable patient/nurse ratios can be easily and accurately achieved in this manner. Staffing requirements and allocation of positions can be objectively quantitated.     

Addressing the nursing work environment to promote patient safety

TOPIC: The nursing work environment has a critical impact on patient safety. Yet confusion on the specific roles and competencies of nurses, staff ratio issues, and lack of nurse empowerment create weaknesses that result in safety risks. PURPOSE: These interrelated issues must be addressed systemically to impact the nursing care system. DISCUSSION: Educational reform focusing upon standardized, higher level nursing education using a military model, appropriate staff ratio laws derived from the outcomes literature, and recurrent training incorporating policy-making powers can result in nurse empowerment and improved patient safety. CONCLUSION: Improving the nursing environment requires a broad approach to benefit patient safety. By treating the work environment as a complex system, approaches can result in greater nurse professionalism, empowerment, and patient safety.     

Nursing care planning. Overview and application to the patient in shock

The systematic nursing process is an essential prerequisite for providing effective care for patients in shock. Nurses use assessment skills to identify actual and potential collaborative problems and nursing diagnoses. Once collaborative problems and nursing diagnoses are identified, the nurse develops appropriate individualized patient outcomes and plans care to accomplish the outcomes and resolve the problems. Nursing actions from the three domains may be included in the care plan. The evaluation phase assesses the adequacy of nursing actions in accomplishing the stated goals and returns the process to the stage of assessment. Application of the nursing care planning process to the patient in shock can be somewhat difficult because of the critical nature of the illness, complex assessment data, and rapidly changing interventions. It is indeed a challenge for the critical care nurse to integrate sound principles of nursing care planning into the busy intensive care environment, but the outcome of improved patient care is worth the effort.     

Nurse-led discharge from high dependency unit

High dependency care is a rapidly evolving area of critical care, with high patient turnover, which ultimately leads to high levels of pressure for beds. There is a growing trend emerging, recognizing the importance and value of nurse-led initiatives in delivering effective nursing care in acute care settings. One specific nurse-led initiative this author has developed is that of nurse-led discharge (NLD) from the high dependency unit (HDU), in order to optimize the utilization of critical care beds within the HDU. An audit of the current practice was undertaken, which ultimately led to the implementation of NLD. Early experiences indicate that HDU beds are now being used more effectively.     

A nursing care classification system for assessing workload and determining optimal nurse staffing in a teaching hospital in China: A pre‐post intervention study

We aimed to evaluate the effectiveness of a nursing care classification system for re‐assessing nurse workload and determining staffing needs. Adequate bed–nurse ratios help manage hospital cost‐efficiency, quality of care and patient safety. A prospective pre‐post intervention study was conducted from January 2010 to December 2012 in 16 medical‐surgical units of a tertiary teaching hospital. Nursing tasks were classified into four grades of care reflecting actual workload. Units were re‐staffed accordingly and bed–nurse ratios compared with government‐authorized bed–nurse ratios. Patient satisfaction, hospital stays and mortality were evaluated pre‐ and poststaffing changes. Average bed–nurse ratio (1:0.41) exceeded the national standard (1:0.40) in 16 units, but was inadequate in five units. Re‐staffing increased average bed–nurse ratio from 1:0.41 to 1:0.48. Patients' satisfaction increased from 96.9% to 97.6%, and hospital stays decreased significantly. Nursing care classification effectively distributes nurse staffing to match patients' care levels, improving patient outcomes.     

Nursing workforce deployment and intensive care unit strain during the COVID-19 pandemic in Victoria,Australia

BackgroundThe COVID-19 pandemic demanded intensive care units (ICUs) globally to expand to meet increasing patient numbers requiring critical care. Critical care nurses were a finite resource in this challenge to meet growing patient numbers, necessitating redeployment of nursing staff to work in ICUs.ObjectiveOur aim was to describe the extent and manner by which the increased demand for ICU care during the COVID-19 pandemic was met by ICU nursing workforce expansion in the late 2021 and early 2022 in Victoria, Australia.MethodsThis is a retrospective cohort study of Victorian ICUs who contributed nursing data to the Critical Health Information System from 1 December 2021 to 11 April 2022. Bedside nursing workforce data, in categories as defined by Safer Care Victoria’s pandemic response guidelines, were analysed. The primary outcome was ‘insufficient ICU skill mix’—whenever a site had more patients needing 1:1 critical care nursing care than the mean daily number of experienced critical care nursing staff.ResultsOverall, data from 24 of the 47 Victorian ICUs were eligible for analysis. Insufficient ICU skill mix occurred on 10.3% (280/2725) days at 66.7% (16/24) of ICUs, most commonly during the peak phase from December to mid-February. The insufficient ICU skill mix was more likely to occur when there were more additional ICU beds open over the ‘business-as-usual’ number. Counterfactual analysis suggested that had there been no redeployment of staff to the ICU, reduced nursing ratios, with inability to provide 1:1 care, would have occurred on 15.2% (415/2725) days at 91.7% (22/24) ICUs.ConclusionThe redeployment of nurses into the ICU was necessary. However, despite this, at times, some ICUs had insufficient staff to cope with the number and acuity of patients. Further research is needed to examine the impact of ICU nursing models of care on patient outcomes and on nurse outcomes.
