What Do We Mean by Staffing?
•
•
•
•
Staffing of licensed personnel
Staffing of assistive and ancillary personnel
Staffing in hospitals
Staffing in long-term care facilities
Research on Nurse Staffing has
Changed in Recent Years
• In the 1990s:
– IOM said there was insufficient evidence to
determine whether nurse staffing changes were
detrimental (Crossing the Quality Chasm, 1996)
– ANA said there was insufficient scientific evidence
to establish ratios (1999)
The newest research shows that nurse
staffing is important
• Evidence suggests that an increase in nurse staffing is
related to decreases in:
–
–
–
–
–
–
risk-adjusted mortality
nosocomial infection rates
thrombosis and pulmonary complications in surgical patients
pressure ulcers
readmission rates
failure to rescue
• Evidence that higher ratios of RNs to residents in longterm care has positive effects
The Most Influential Studies
• Report for Health Resources and Services
Administration
– Use of administrative hospital data from states
– Key outcomes associated with nurse staffing:
•
•
•
•
•
•
Urinary tract infections
Pneumonia
Length of stay
Upper gastrointestinal bleeding
Shock
Failure to rescue
Needleman, J., Buerhaus, P., Mattke, S., Stewart, M., & Zelevinsky, K. (2002). Nurse-staffing
levels and the quality of care in hospitals. New England Journal of Medicine, 346, 17151722.
The Most Influential Studies
• Survey of nurses about staffing and work environment in Pennsylvania,
surveys linked to discharge data
– For every patient added to the average hospital-wide nurse workload
– 7% increase in mortality for every patient added to the
– 7% increase in failure-to-rescue patients with complications
• Patients in hospitals with 8:1 patient to nurse ratios have more than a
30% greater risk of death following common surgical procedures than
patients in hospitals with 4:1 ratio
• Some 4 million surgical procedures like the ones studied are
performed annually in US hospitals.
– If all patients were cared for in hospitals with 4 patients per
nurse, up to 20,000 fewer deaths might be expected.
Aiken, L.H., Clarke, S.P., Sloane, D.M., Sochalski, J., & Silber J.H. (2002). Hospital nurse staffing and
patient mortality, nurse burnout, and job dissatisfactions. Journal of the American Medical
Association, 288, 1987-1993.
The Most Influential Studies
• Cross-sectional analyses of outcomes data for 232,342
general, orthopedic, and vascular surgery patients
discharged from 168 nonfederal adult general
Pennsylvania hospitals
– Hospitals with more baccalaureate-educated RNs had lower:
– 30-day mortality
– Failure to rescue

hospital nurses and surgical patient mortality. . Journal of the American Medical
Association, 290, 1617-1623.
The Most Influential Studies
• Data for patients aged 18 years and older who were
discharged between 1990 and 1996 were used to
create hospital-level adverse event indicators.
– Examined relationship between nurse staffing and four
postsurgical adverse events:
•
•
•
•
venous thrombosis/pulmonary embolism
pulmonary compromise after surgery
urinary tract infection
pneumonia
– Poor nurse staffing increased pneumonia rates
Kovner, C., Jones, C., Zahn, C., Gergen, P.J., & Basu, J. (2002). Nurse staffing and postsurgical adverse
events: An analysis of administrative data from a sample of U.S. hospitals, 1990-1996. Health
Serves Research, 37, 611-629.
Nurse staffing also affects job
satisfaction
• High workload and poor staffing ratios are
associated with:
– Nurse burnout
– Low job satisfaction
– Increased nurse stress
• Nurse stress is related to:
– Adverse patient events
– Nurse injuries
– Quality of care
– Patient satisfaction
Importance of Work Environment
• Every blue ribbon commission report on
solutions to cyclical nursing shortages since
1980 has recommended changes in nurses’
work environments
– Recent reports: JCAHO, AHA, RWJF
• However, on the whole nurses work
environments have deteriorated over the past
2 decades

– Reports from 43,000 nurses from more than 700
hospitals in the United States, Canada, England,
Scotland, and Germany in 1998-1999
– Core problems in work design and workforce
management threaten the provision of care

Patient to Nurse Ratios Important
in Nurse Retention
• Higher burnout and greater job dissatisfaction
are strongly related to patient-to-nurse ratios.
– An increase of 1 patient per nurse increases the
probability of
• high levels of burnout by 23%
• job dissatisfaction by 15%
Aiken, L.H., Clarke, S.P., Sloane, D.M., Sochalski, J., & Silber J.H. (2002). Hospital nurse staffing and
patient mortality, nurse burnout, and job dissatisfactions. Journal of the American Medical
Association, 288, 1987-1993.
The Research Has Limits
• Data on hospitals do not recognize different
staffing on different units
• Studies at the nursing unit level involve
primary data collection and are costly
• Single-year studies cannot prove a causal
relationships
• No study identifies the “ideal” staffing ratio
Objectives
• Review research on the relationship between
staffing and quality of care
• Present data on staffing in the United States
• Explore staffing-related policy options for
ensuring quality of care
There are many sources for nurse
staffing data
• American Hospital Association
• State data
• Original surveys
There are many ways to measure nurse
staffing
• Nurse-to-patient ratios
– 1:4, 1:8, 1:12
• Hours per patient day (HPPD)
• Full-time equivalent employment (FTEE)
– Someone who does 100% patient care = 1 FTEE
– Someone who does 50% administration and 50%
patient care = 0.5 FTEE
• Skill mix (how many RNs, LPNs, BSNs, PCTs??)

Rules and Regulations
Some States Have Adopted
Some Rules
• California
– Hospitals must have a patient acuity system to determine
staffing (1995)
• Kentucky and Virginia (1998)
– Hospitals must establish appropriate staffing methodology
• Nevada (1999)
– Hospitals must have a staffing methodology based on acuity
Some States Have Adopted
Some Rules
• Oregon (2001)
– Hospitals must develop and implement staffing plans
– Provisions for inspections and penalties established
• Texas (2002)
– Hospitals must adopt, implement, and enforce a written
staffing plan
• California
– Hospitals must meet specific minimum nurse-to-patient ratios
(1999, implemented 2004)
Florida 2005
• HB 1117 proposed the creation of the Safe
Staffing for Quality Care Act, which would
require ratio limits on nursing units

• Senate Bill 1176 also referred to the Safe
Staffing for Quality Care Act and aimed to
prescribe staffing standards for health care
facilities.
– Died in Committee on Health Care

Florida 2005
• Both Bills were
– Supported by the Nurse Alliance of Florida, a labor union in
south Florida
• “Staffing ratios are crucial to patient safety, nurse satisfaction and
hospital costs.”
– Maria Sanchez, member of the Alliance
– Opposed by the Florida Nurses Association
• “First of all, it is a nursing judgment to decide what care patients
need. Second, ratios make all nurses the same. Every nurse, no
matter how much experience or schooling she has, becomes a
number. It’s demeaning to the profession, and when you put numbers
on units, there’s no flexibility. It ties the hands of the nurses
themselves.”
– Barbara Lumpkin, Associate Executive Director, FNA
Approaches to Staffing Standards
•Patient acuity/patient classification systems
•Fixed ratios
•Formula-based ratios
•Skill-mix requirements
Patient Acuity/Patient Classification
Systems
• Input: # of patients, acuity of illness
• Output: appropriate staffing levels
• Widely marketed systems and home-grown
systems
• Problems:
– Systems best for long-term, not short-term,
prediction
– Difficulty of staffing up if necessary
– Enforcement – hard to monitor
Fixed Ratios
• Fixed, specific nurse-to-patient ratios are
mandated
• Problems:
– Minimum staffing could become average staffing
– Hospitals could eliminate ancillary and support
staff
– Enforcement – do you close hospitals?
– Loss of flexibility and innovation
Formula-based Ratios
• Nurse workload = function of:
– RN staff expertise
– Patient acuity, work intensity
– Support staff, MD availability
– Unit physical layout
• Problems:
– Defining the function
– Establishing new staffing ratios every
week/month/year
– Enforcement
Skill-mix Requirements
• Hospitals must have a minimum fixed ratio of
licensed staff relative to all staff
• Problems:
– What is the appropriate ratio?
– Minimum ratio could become average (like speed limit)
– Total staffing may not be adequate
– Loss of flexibility and innovation
– Enforcement
An Overriding Question
• How much are we willing to spend to increase
quality of care?
– Do we take money from schools?
– Do we take money from salaries?
– Do we increased the number of uninsured?
What Next?
• More nurses lead to better patient outcomes
• Legislative approaches have potential pitfalls
• To improve nurse staffing:
– Hospitals need money to pay more staff
– More nurses are needed in the labor market
Responses to Hospital
Nursing Shortages
• Responding to a nursing shortage in the early 1980s,
the American Academy of Nursing embarked on the
“magnet hospital” project
– Identify hospitals that attract and retain nurses.
– 1993 - the "magnet" concept by was formalized by the ANCC
by establishing the Magnet Hospital Recognition Program for
Excellence in Nursing Services
