People have the right to be involved in discussions and make informed decisions about their care, as described in NICE's information on making decisions about your care.
Making decisions using NICE guidelines explains how we use words to show the strength (or certainty) of our recommendations, and has information about prescribing medicines (including off-label use), professional guidelines, standards and laws (including on consent and mental capacity), and safeguarding.
Assessing the nursing needs of individual patients is paramount when making decisions about safe nursing staff requirements for adult inpatient wards in acute hospitals. Consequently this guideline makes a series of recommendations that focus on safe nursing for adult inpatient wards in acute hospitals. Assessment of patients' nursing needs should take into account individual preferences and the need for holistic care and patient contact time.
This guideline begins with recommendations for the responsibilities and actions at an organisational level to support safe staffing for nursing in individual acute adult inpatient wards.
There is no single nursing staff-to-patient ratio that can be applied across the whole range of wards to safely meet patients' nursing needs. Each ward has to determine its nursing staff requirements to ensure safe patient care. This guideline therefore makes recommendations about the factors that should be systematically assessed at ward level to determine the nursing staff establishment. It then recommends on-the-day assessments of nursing staff requirements to ensure that the nursing needs of individual patients are met throughout a 24-hour period.
The guideline also makes recommendations for monitoring and taking action according to whether nursing staff requirements are being met and, most importantly, to ensure patients are receiving the nursing care and contact time they need on the day. The emphasis should be on safe patient care not the number of available staff. This includes recommendations to review the nursing staff establishment for the ward and adjust it if required.
1.1 Organisational strategy
These recommendations are for hospital boards, senior management and commissioners. They should be read alongside the National Quality Board's guide on how to ensure the right people, with the right skills, are in the right place at the right time. A guide to nursing, midwifery and care staffing capacity and capability.
Focus on patient care
1.1.1
Ensure patients receive the nursing care they need, including specialist nursing, regardless of the ward to which they are allocated, the time of the day or the day of the week. This includes planning to locate patients where their clinical needs can best be met.
Accountability for ward nursing staff establishments
1.1.2
Develop procedures to ensure that ward nursing staff establishments (the number of registered nurse and healthcare assistant posts that are funded to work in particular wards) are sufficient to provide safe nursing care to each patient at all times.
1.1.3
Ensure that the final ward nursing staff establishments are developed with the registered nurses who are responsible for determining nursing staff requirements at a ward level and approved by the chief nurse (or delegated accountable staff). The board should retain organisational responsibility. (See the section 1.3 on setting the ward nursing staff establishment for recommendations on setting ward nursing staff establishments.) This includes when the ward establishment and budget are set.
1.1.4
Ensure senior nursing managers are accountable for the nursing staff roster that is developed from the ward nursing staff establishment.
1.1.5
When agreeing the ward nursing staff establishment, ensure it is sufficient to provide planned nursing staff requirements at all times. This should include capacity to deal with planned and predictable variations in nursing staff available, such as annual, maternity, paternity and study leave (commonly known as uplift). Consider adjusting the uplift for individual wards where there is evidence of variation in planned or unplanned absence at a ward level.
1.1.6
When agreeing the ward nursing staff establishment, ensure capacity to deal with fluctuations in patients' nursing needs (such as seasonal variations indicated by historical records of nursing staff requirements) and staff unplanned leave or absences.
1.1.7
When agreeing the skill mix of the ward nursing staff establishment, this should be appropriate to patient needs and take into account evidence that shows improved patient outcomes are associated with care delivered by registered nurses (see recommendation 1.3.6).
Responsiveness to unplanned changes
1.1.8
Ensure that there are procedures to identify differences between on-the-day nursing staff requirements and the nursing staff available on a ward.
1.1.9
Hospitals need to have a system in place for nursing red flag events (see the section 1.4 on assessing if nursing staff available on the day meet patients' nursing needs) to be reported by any member of the nursing team, patients, relatives or carers to the registered nurse in charge of the ward or shift.
1.1.10
Ensure there are procedures for effective responses to unplanned variations in predicted patients' nursing needs or the availability of nursing staff at any time during the day and night. These procedures should include prompt action to enable an increase or decrease in nursing staff.
1.1.11
Action to respond to nursing staff deficits on a ward should not compromise staff nursing on other wards.
1.1.12
Ensure there is a separate organisational contingency plan and response for patients who require the continuous presence of a member of the nursing team (often referred to as 'specialing' care).
1.1.13
Consider implementing approaches to support flexibility, such as adapting nursing shifts, nursing skill mix, assigned location and employment contract arrangements.
Monitor adequacy of ward nursing staff establishments
1.1.14
Ensure that there are procedures for systematic ongoing monitoring of safe nursing indicators (see section 1.5, monitor and evaluate ward nursing staff establishments) and formal review of nursing staff establishments of individual wards at a board level at least twice a year (and more often if there are significant changes such as ward patient characteristics). These procedures should include periodic analysis of reported nursing red flag events and the safe nursing indicators (see section 1.5, monitor and evaluate ward nursing staff establishments).
1.1.15
Make appropriate changes to the ward nursing staff establishment in response to the outcome of the review.
1.2 Principles for determining nursing staff requirements
These recommendations are for registered nurses in charge of individual wards or shifts who should be responsible for assessing the various factors used to determine nursing staff requirements.
1.2.1
Use a systematic approach that takes into account the patient, ward and staffing factors in box 1 to determine nursing staff requirements both when setting the ward nursing staff establishment and when making on-the-day assessments.
1.2.2
Use a decision support toolkit endorsed by NICE to facilitate the systematic approach to determining the nursing staff requirements (see the details of the process for assessing toolkits).
1.2.3
Use informed professional judgement to make a final assessment of nursing staff requirements. This should take account of the local circumstances, variability of patients' nursing needs, and previously reported nursing red flag events (see section 1.4 on assessing if nursing staff available on the day meet patients' nursing needs).
1.2.4
Consider using the nursing care activities summarised in tables 1 and 2 as a prompt to help inform professional judgement of the nursing staff requirements. Tables 1 and 2 may help to identify where patients' nursing needs are not fully accounted for by any decision support toolkit that is being used.
Box 1: Factors to determine nursing staff requirements
Patient factors
-
Use individual patient's nursing needs as the main factor for calculating the nursing staff requirements for a ward. (The term patient nursing needs is used throughout this guideline to include both patient acuity and patient dependency.)
-
Make a holistic assessment of each patient's nursing needs and take account of specific nursing requirements and disabilities, as well as other patient factors that may increase nursing staff requirements, such as:
-
difficulties with cognition or confusion (such as those associated with learning difficulties, mental health problems or dementia)
-
end-of-life care
-
increased risk of clinical deterioration
-
need for the continuous presence of a member of the nursing team (often referred to as 'specialing' care).
Ward factors
-
Expected patient turnover in the ward during a 24-hour period (including both planned and unscheduled admissions, discharges and transfers).
-
Ward layout and size (including the need to ensure the safety of patients who cannot be easily observed, and the distance needed to travel to access resources within the ward).
Nursing staff factors
These activities and responsibilities may be carried out by more than one member of the nursing team.
Support from non-nursing staff such as the medical team, allied health professionals and administrative staff.
Abbreviations: IV, intravenous; PRN medication, medication administered as needed
Note: these activities are only a guide and there may be other ongoing activities that could be considered
Note: these activities are only a guide and there may be other one-off activities that also could be considered
1.4 Assessing if nursing staff available on the day meet patients' nursing needs
These recommendations are for the registered nurses on wards who are in charge of shifts.
1.4.1
Systematically assess that the available nursing staff for each shift or at least each 24-hour period is adequate to meet the actual nursing needs of patients currently on the ward. The nurse in charge on individual shifts should make the on-the-day assessments of nursing staff requirements, which could be facilitated by using a NICE-endorsed decision support toolkit. Also take into account the patient factors outlined in section 1.2 on principles for determining nursing staff requirements, box 1 and tables 1 and 2.
1.4.2
Monitor the occurrence of the nursing red flag events shown in box 2 throughout each 24-hour period. Monitoring of other events may be agreed locally.
1.4.3
If a nursing red flag event occurs, it should prompt an immediate escalation response by the registered nurse in charge. An appropriate response may be to allocate additional nursing staff to the ward.
1.4.4
Keep records of the on-the-day assessments of actual nursing staff requirements and reported red flag events so that they can be used to inform future planning of ward nursing staff establishments or other appropriate action.
Box 2: Nursing red flags
-
Unplanned omission in providing patient medications.
-
Delay of more than 30 minutes in providing pain relief.
-
Patient vital signs not assessed or recorded as outlined in the care plan.
-
Delay or omission of regular checks on patients to ensure that their fundamental care needs are met as outlined in the care plan. Carrying out these checks is often referred to as 'intentional rounding' and covers aspects of care such as:
-
Pain: asking patients to describe their level of pain level using the local pain assessment tool.
-
Personal needs: such as scheduling patient visits to the toilet or bathroom to avoid risk of falls and providing hydration.
-
Placement: making sure that the items a patient needs are within easy reach.
-
Positioning: making sure that the patient is comfortable and the risk of pressure ulcers is assessed and minimised.
-
A shortfall of more than 8 hours or 25% (whichever is reached first) of registered nurse time available compared with the actual requirement for the shift. For example, if a shift requires 40 hours of registered nurse time, a red flag event would occur if less than 32 hours of registered nurse time is available for that shift. If a shift requires 15 hours of registered nurse time, a red flag event would occur if 11 hours or less of registered nurse time is available for that shift (which is the loss of more than 25% of the required registered nurse time).
-
Less than 2 registered nurses present on a ward during any shift.
Note: other red flag events may be agreed locally.
There is an illustration of process example on the NICE website to illustrate the use of recommendations in section 1.3 on setting the ward nursing staff establishment and section 1.4 on assessing if nursing staff available on the day meet patients' nursing needs.
1.5 Monitor and evaluate ward nursing staff establishments
These recommendations are for senior management and nursing managers or matrons to support safe staffing for nursing at a ward level.
1.5.1
Monitor whether the ward nursing staff establishment adequately meets patients' nursing needs using the safe nursing indicators in box 3. These are indicators that evidence shows to be sensitive to the number of available nursing staff and skill mix. Consider continuous data collection of these safe nursing indicators (using data already routinely collected locally where available) and regularly analyse the results. (The section on safe nursing indicators gives further guidance on data collection for the safe nursing indicators.)
1.5.2
Compare the results of the safe nursing indicators with previous results from the same ward at least every 6 months. The comparisons should also take into account the specific ward and patient characteristics (such as patient risk factors and ward speciality). Reported nursing red flag events (see section 1.4 on assessing if nursing staff available on the day meet patients' nursing needs, box 2) should also be reviewed when undertaking this monitoring and prompt an earlier examination of the adequacy of the ward nursing staff establishment.
1.5.3
There is no single nursing staff-to-patient ratio that can be applied across all acute adult inpatient wards. However, take into account that there is evidence of increased risk of harm associated with a registered nurse caring for more than 8 patients during the day shifts. Therefore if the available registered nurses for a particular ward (excluding the nurse in charge) are caring for more than 8 patients during the day shifts, the senior management and nursing managers or matrons should:

See the section on safe nursing indicators for further information
Patient reported outcome measure
Data can be collected for the following indicators from the National Inpatient Survey:
-
Adequacy of meeting patients' nursing care needs.
-
Adequacy of provided pain management.
-
Adequacy of communication with nursing team.
Safety outcome measures
-
Falls: record any fall that a patient has experienced. The severity of the fall could be further defined in accordance with National Reporting and Learning System categories: no harm; low harm; moderate harm; severe harm; death.
-
Pressure ulcers: record pressure ulcers developed or worsened 72 hours or more after admission to an organisation. The patient's worst new pressure ulcer could be categorised as grade 2, 3 or 4.
-
Medication administration errors: record any error in the preparation, administration or omission of medication by nursing staff. The severity of the error should also be recorded.
Staff reported measures
-
Missed breaks: record the proportion of expected breaks that were unable to be taken by nursing staff working on inpatient hospital wards.
-
Nursing overtime: record the proportion of nursing staff on inpatient hospital wards working extra hours (both paid and unpaid).
Ward nursing staff establishment measures
Data can be collected for some of the following indicators from the NHS England and Care Quality Commission joint guidance to NHS trusts on the delivery of the 'Hard Truths' commitments on publishing staffing data regarding nursing, midwifery and care staff levels and more detailed data collection advice since provided by NHS England.
-
Planned, required and available nursing staff for each shift: record the total nursing hours for each shift that were planned in advance, were deemed to be required on the day of the shift, and that were actually available, plus the bed utilisation during the same period.
-
High levels and/or ongoing reliance on temporary nursing: record the proportion of nursing hours provided by bank and agency nursing staff on inpatient hospital wards. (The agreed acceptable levels should be established locally.)
Compliance with any mandatory training in accordance with local policy (this is an indicator of the adequacy of the size of the ward nursing staff establishment).
Note: other safe nursing indicators may be agreed locally.
Terms used in this guideline
This section defines terms that have been used in a particular way for this guideline.
Adult inpatient wards in acute hospitals
Wards that provide overnight care for adult patients in acute hospitals, excluding intensive care, high dependency, maternity, mental health, day care, acute admission or assessment units or wards. Other than these exceptions, the guideline covers all general and specialist inpatient wards for adults in acute hospitals.
Bed utilisation
The number of patients that the ward nursing team is responsible for during each 24‑hour period. This includes patients who are discharged or transferred to another ward during the 24‑hour period.
Healthcare assistant
Healthcare assistants are all unregistered clinical staff working in hospital or community settings under the guidance and supervision of a registered healthcare professional. They may have a variety of titles such as healthcare support worker, nursing auxiliary and nursing assistant. In this guideline, the term healthcare assistants also includes assistant practitioners. The responsibilities of healthcare assistants vary, depending upon the healthcare setting and their level of training and competence.
Missed care
When a patient does not receive an aspect of planned care that has been assessed by healthcare professionals as being required. Care may be delayed, performed to a suboptimal level, omitted or inappropriately delegated.
Nursing hours per patient
This is how the measure of nursing staff requirements could be expressed. It represents the number of hours of nursing time (for both direct patient care and other nursing activities) provided by registered nurses and healthcare assistants per patient over a defined period. This is an alternative to expressing nursing time as a ratio of how many patients each nurse cares for. The 2 measurements are interchangeable. For example, a registered nurse or healthcare assistant working an 8-hour shift (after accounting for breaks) can contribute 8 hours of nursing time that day, which includes direct patient care as well as other necessary nursing activities.
Nursing red flag events
Events that prompt an immediate response by the registered nurse in charge of the ward. The response may include allocating additional nursing staff to the ward or other appropriate responses.
Nursing skill mix
The composition of the nursing team in terms of qualification and experience. This is typically expressed as a percentage of registered nurses to healthcare assistants. Nursing skill mix should also encompass individual clinical competencies and different areas of expertise and grades of registered nurses healthcare assistants.
Nursing staff
This refers to registered nurses and healthcare assistants, unless otherwise specified.
Nursing staff requirement
The nursing staff required by each ward. This should take into account all nursing care needs of patients, ward factors and staff factors including nursing activities other than direct patient care. This can be expressed as number of nursing hours.
Nursing staff roster
The daily staffing schedule for registered nurses and healthcare assistants to work on an individual ward.
Patient acuity
This refers to how ill the patient is, their increased risk of clinical deterioration and how complex their care needs are. This term is sometimes used interchangeably with the terms 'patient complexity' and 'nursing intensity'.
Patient dependency
The level to which the patient is dependent on nursing care to support their physical and psychological needs and activities of daily living, such as eating and drinking, personal care and hygiene, mobilisation.
Patients' nursing needs
The total nursing care needed by each patient on an individual ward that has been assigned to the nursing profession. This term is used throughout the guideline to include both patient acuity and patient dependency.
Patient turnover
Rate of movement of patients into and out of a ward. This can be calculated by the number of patient admissions, discharges and internal transfers during a defined period of time.
Registered nurse
A registered nurse holds active registration with the Nursing and Midwifery Council with a licence to practise.
Nursing is a regulated profession for registered nurses, but they may appropriately delegate and supervise the delivery of nursing activities to healthcare assistants.
Safe nursing care
When reliable systems, processes and practices are in place to meet required care needs and protect people from missed care and avoidable harm.
Ward nursing staff establishment
The number of registered nurses and healthcare assistants funded to work in a particular ward, department or hospital. This includes all nursing staff in post, as well as unfilled vacancies or vacancies being covered by temporary staff. Ward nursing staff establishments are usually expressed in number of whole time equivalents.
