ABSTRACT
This paper describes the results of using a modified
Delphi approach designed to achieve consensus from
eight discharge planning experts regarding the
decision to refer hospitalized older adults for postdischarge follow-up. Experts reviewed 150 cases
using an online website designed to facilitate their
interaction and efforts to reach agreement on the need
for a referral for post-discharge care and the
appropriate site for such care. In contrast to an
average of eight weeks to complete just 50 cases
using the traditional mail method, the first online
Delphi round for 150 cases were completed in six
weeks. Data provided by experts suggest that online
Delphi is a time efficient and acceptable
methodology for reaching group consensus. Other
benefits include instant access to Delphi decision
results, live knowledge of the time requirements and
progress of each expert, and cost savings in postage,
paper, copying, and storage of paper documents. This
online Delphi methodology is highly recommended.
INTRODUCTION
Hospital discharge referral decision-making is a
complex, multidisciplinary process with many
barriers, challenges, and shortfalls. Shortened lengths
of hospital stay, inconsistent assessment criteria, and
varying levels of expertise and risk tolerance in
clinical decision making are among the barriers that
impede the ability to make accurate referral decisions
1, 2, 3
Older adults with multiple co-morbid conditions
and complex treatment regimes add to the challenge.
Inadequate discharge planning and referral decisionmaking can result in elders being discharged before
the full effect of treatment is evident, the patient and
family fully understand the illness or the treatment
plan, and the patient can assume self-care. 2, 3, 4 Some
believe the problem is so widespread that virtually all
patients older than 60 leave the hospital with unmet
needs.3 The care of these older adults is rapidly
transferred from formal hospital care to the informal
care of unskilled family caregivers. When referrals
for follow-up professional care are missed, older
adults with unmet needs suffer costly rehospitalizations, emergency room use, difficulties
with activities of daily living, and declines in selfreported health.5, 6, 7, 8, 9 These adverse outcomes are
very costly to the older adults, their families, and
society, therefore it is critically important to
understand and improve the process by which referral
decisions are made.
To address these issues, our team is in year two of a
National Institute of Nursing Research funded study
to develop an expert system to support discharge
referral decision-making. The system will assist
multidisciplinary clinicians to collect and synthesize
key information to support accurate decision making
when referring patients for services in home care,
inpatient and outpatient settings, and nursing homes.
National and local experts in discharge planning are
identifying the factors that drive post discharge
referrals. We are using these factors to develop a
rule-based decision support system. In order to
ensure that the knowledge base is as robust as
possible and that it represents the array of best
practices proposed by the experts, we developed a
modified online Delphi technique to reach consensus.
Consensus means that all eight experts agree on the
referral decision and site of care for each case. The
purpose of this paper is to share our online Delphi
methodology and to discuss the results and benefits
we realized by using this approach to support the
goals of the parent study.
METHODS
Expert profiles
The goal of the parent study is to develop a validated
knowledge base for discharge planning decision
support. In order to meet this goal, we included
representatives from all of the clinical domains
involved in discharge planning, including nursing,
physical therapy, social work, and medicine. These
individuals include four nationally known scholars
and four local clinical discharge-planning experts.
Their charge is to make referral decisions and
AMIA 2003 Symposium Proceedings − Page 106
identify the factors that drive discharge referral
decisions for a series of case studies, described
below.
Each of the experts was required to have at least five
years of clinical or research experience in discharge
planning or decision making for older adults. Experts
were chosen to ensure diverse viewpoints with
national, scholarly, local, and clinical perspectives.
The national and scholarly perspectives came from
four experts from different areas of the country
including the Northeast, Midwest, and West. The
four local experts provided the clinical perspective
with their knowledge about the day-to-day
operations, workflow, and issues about discharge
decision-making.
Case studies
We generated a series of 200 case studies from the
clinical and research files of adults aged (65 – 90)
who were hospitalized for a variety of medical and
surgical diagnoses. These diagnoses included
congestive heart failure, respiratory tract infection,
coronary bypass surgery, cardiac valve replacement,
major small and large bowel procedures,
angina/myocardial infarction, and orthopedic
procedure of the lower extremities. Cases were
generated from three previous clinical trials that
evaluated transitional care. Data collected on each
subject in these studies included medical and surgical
history, medication and other therapies, adverse
events, self-rated health, functional status,
depression, health care utilization, and social support.
These data were summarized to create individual case
studies, which were presented in a standardized
structured format. The case studies were mailed to
each expert for discharge assessment. This
assessment was limited to four possible discharge
dispositions: home care, inpatient facility, outpatient
care, or nursing home.
This initial assessment indicated that there was
considerable lack of agreement among the experts
with regard to discharge disposition. At this point,
we decided to employ a Delphi approach to facilitate
consensus building.
The Delphi technique
The Delphi methodology is a predominantly
qualitative approach in which expert opinion is
determined through iterative rounds where
respondents individually receive feedback about
group opinions. Since information is shared
confidentially and without personal contact between
respondents, the biasing effects of peer pressure,
seniority, or personality are minimized. 10 This
technique is typically implemented asynchronously
using mail or other media.
