ABSTRACT
|
|---|
OBJECTIVE To evaluate 1) the new ulceration, the new
major amputation, and the survival rates of 115 diabetic subjects hospitalized
for foot ulceration from 1990 to 1993, with an average follow-up of 6.5 years,
and 2) the demographic and clinical characteristics associated with
these events.
RESEARCH DESIGN AND METHODS A total of 115 subjects, 31 women
and 84 men, were monitored until 31 December 1998. All subjects were provided
with therapeutic shoes and received intense education. Data concerning new
ulceration, new major amputation, and reamputation events and the date and
cause of death were recorded for each patient. The prognostic factors for
these events were then evaluated.
RESULTS The average follow-up was 78.3 ± 15.3 months
(range 60-106). During this time, 13 homolateral and 12 contralateral episodes
of new ulceration occurred. At univariate analysis, none of the variables
considered were significantly associated with the new ulceration. There were
three major amputations: two of the limb previously healed and one of the
contralateral limb. Of the 115 subjects, 51 (44.3%) died: 24 of the 31 women
(77.4%) and 27 of the 84 men (32.1%). Ischemic cardiopathy was the most
frequent cause of death (60.8%). Mortality concerned 20 of the 27 subjects
(74.1%) undergoing major amputation from 1990 to 1993 and 31 of the 88 healed
subjects (35.2%), with a significant difference (P < 0.0001).
Multivariate analysis showed the independent role of the ankle-brachial index
0.5 (P = 0.005), age (P = 0.003), and female sex
(P = 0.027).
CONCLUSIONS We believe that the use of therapeutic shoes and
intense educational training, including the education of the family, have
contributed to the low incidence of new ulceration and major amputation in our
study population. The high frequency of ischemic cardiopathy as a cause of
death should, perhaps, lead to a more aggressive diagnostic and therapeutic
attitude toward this pathology in diabetic subjects admitted to hospitals for
foot ulceration.

INTRODUCTION
|
|---|
Many epidemiological reports have published data regarding foot ulceration,
amputation, and relative risk factors
(1,2,3,4,5)
in diabetic subjects, although data on new ulceration and new amputation in
diabetic subjects with foot ulceration is scarce
(6,7).
There are reports on the survival of diabetic amputees
(7,8,9),
but there are few studies on the survival of diabetic subjects hospitalized
for foot ulceration (10). The
available data vary according to the selection criteria of the population
being studied; such criteria may consist of ethnic group
(11), age
(12), level of amputation
(13), or subjects undergoing
only vascular procedures (14).
The duration of observation varies. Silbert
(15) and Whitehouse et al.
(16) reported a long
follow-up, but these studies are not recent. More recent studies only monitor
patients for 2-4 years
(9,10,13,17,18).
 |
RESEARCH DESIGN AND METHODS
|
|---|
Between 1990 and 1993, 115
diabetic subjects were hospitalized for foot ulceration at our center
(19); they were monitored
after discharge until 31 December 1998. The reported data concerned the new
ulceration, the new major amputation, and the survival rates of these
subjects. We evaluated prognostic factors for these events.
Patient characteristics
The clinical characteristics investigated between 1990 and 1993 were
reported in Table 1. During that
period, 27 subjects (23.5%) underwent major amputation (above the ankle), and
two of these subjects died in the hospital from septic shock. A total of 88
subjects (76.5%) were considered healed, 53 of whom recovered with and 35
without minor amputation. Of the 115 patients, 95 (82.6%) had sensorimotor
diabetic neuropathy and 97 (84.3%) had peripheral vascular disease
(ankle-brachial index [ABI] <0.9, trancutaneous oximetry on the dorsum of
the foot 50 mmHg, and a peripheral angiography positive for occlusive
disease). A total of 18 (15.7%) patients were considered purely neuropathic
and 97 (84.3%) were ischemic or neuroischemic. Of these patients, 29 (29.9%)
underwent vascular procedures (19 peripheral transluminal angioplasties and 10
bypass grafts).
Follow-up
All 115 subjects were monitored until 31 December 1998. The subjects from
our region (57.4%) were examined approximately every 2 months, and patients
not living near our center (42.6%) were examined once a year. Patients and
families were instructed to visit the center if any sign of lesion
appeared.
All of the subjects who had undergone a major amputation were given
prostheses 3 months after discharge. Approximately 1 month after
discharge, all of the healed subjects were provided with extra-deep rocker
shoes with soft thermoformable leather (Buratto, Crocetta del Montello, Italy)
and customized insoles, shaped by a cast, in Alkaform (derived from
Plastazote) and Alcapy (derived from Professional Protective Technology, Deer
Park, NY). In addition, all patients, including amputees, received a
therapeutic shoe for the unaffected foot. The insoles were modified or changed
every 6 months, and the shoes were modified according to wear.
End points
New ulceration was defined as any ulceration at the same or different site
of a previous ulcer or an ulcer in the contralateral foot. Major amputation
refers to that performed above the ankle.
We examined 196 limbs: 2 limbs in 81 healed subjects, 1 limb in 7 subjects
who had undergone a major amputation before 1990, and the remaining limbs of
the 27 subjects who had undergone a major amputation during hospitalization
from 1990 to 1993. All of the following were recorded: homolateral and
contralateral new ulceration, major amputation of the limb healed during
hospitalization, reamputation of the same limb in the subjects undergoing
major amputation from 1990 to 1993, major amputation of the contralateral
limb, and date and cause of death.
Table 1 shows the association
between the incidence of events and the considered variables. However, because
we did not consider HbAlc and because procedural methods for and
frequency of the determination of variables differed for subjects living far
from the center, the data are not reliable.
Statistical analysis
From the time of hospital discharge (time 0), Kaplan-Meier survival curves
were calculated for all causes of death, and the crude percentage of survivors
was reported according to the modalities of discrete variables or classes of
continuous variables observed at the cutoff points reported in the tables. All
patients were exposed to risk of death for at least 5 years.
We used the log-rank test for comparing groups with respect to survival,
and we performed a univariate analysis using Cox's regression model to
identify the prognostic role of the considered variables. P < 0.05
was sufficient to statistically prove the association with patient survival
time. We did the same analysis with a multivariate Cox's regression model and
a stepwise selection of variables to identify the prognostic factors
independently associated with new ulceration and survival time. The entry
criterion was P 0.10, and the permanence criterion was
P 0.05. For dichotomous variables, the constants estimate the
mortality hazard ratios and the 95% CIs of the hazard ratios. For age, the
hazard ratio and its CI refer to the unitary increment (1 year).
The proportional hazard assumptions were tested graphically for all of the
variables with the plot of log {log [survivors proportion
(t)]} versus survival time (t). Elaboration was performed
with STATA 5.0 (Stata, College Station, TX) survival analysis routines.

RESULTS
|
|---|
The mean follow-up was 78.3 ± 15.3 months
(minimum 60 months and maximum 106 months).
New ulceration
According to the Wagner classification system, there were 25 (12.75%)
episodes of new ulceration: 4 grade IV, 3 grade III, 4 grade II, and 14 grade
I episodes. All 25 episodes, 13 homolateral and 12 contralateral in terms of
the first ulceration, occurred in 23 of the 88 subjects who recovered in the
period between 1990 and 1993. No ulceration occurred on the stumps of the
amputees. A total of 12 patients were hospitalized, 13 were treated in the
outpatients' department, 3 underwent amputation below the knee, 5 underwent
amputation of one or two toes, and 17 recovered without amputation. The
average period of time the subjects were free from new ulceration was 32.7
± 23.8 months. At univeriate analysis, no variable in
Table 1 was significantly
associated with new ulceration.
Major amputation
No reamputation of the same limb was carried out in the 27 patients
undergoing major amputation in the 1990-1993 period. In the 88 subjects healed
without major amputation, three major amputations were performed: one of the
contralateral limb and two of the same limb healed in the 1990-1993 period.
The average period of time the subjects were free from amputation was 9.3
± 3.2 months: 7.5 months for amputation of the same limb and 13 months
for amputation of the contralateral limb. Because of the small number of major
amputation events, we decided that the possible association with the variables
in Table 1 was not
significant.
Survival
By 31 December 1998, 64 (55.7%) subjects were alive, and 51 (44.3%) had
died (24 of 31 women [77.4%] and 27 of 84 men [32.1%]). Mortality concerned 20
of the 27 (74.1%) subjects who underwent major amputation in the 1990-1993
period and 31 of the 88 (35.2%) healed subjects with a highly significant
difference (hazard ratio 3.020, 95% CI 1.71-5.33, P < 0.0001).
Table 2 shows the causes of
death. Figure 1 shows the
cumulative survival curve and the survival curve by major amputation carried
out during hospitalization from 1990 to 1993.

The results of univariate analysis are shown in
Table 3. The multivariate
analysis of the variables that were found to be associated with death during
univariate analysis confirmed the independent role of ABI 0.5 (hazard
ratio 2.29, 95% CI 1.29-4.08, P = 0.005), age (hazard ratio by
increase of 1 year 1.05, 95% CI 1.02-1.08, P = 0.003), and the female
sex (hazard ratio 1.96, 95% CI 1.08-3.56, P = 0.027). In
Fig. 2, the relative survival
curves are illustrated. The association with major amputation carried out
during hospitalization from 1990 to 1993 is alternative to ABI 0.5.

CONCLUSIONS
|
|---|
Published data concerning new ulceration are
scarce. One study (20) during
the 1960s showed a 23% increase in rate of ulceration of the opposite
extremity within a year in diabetic subjects amputated for gangrene. Only 6%
had an intact contralateral limb after 5 years. Recurrence rates for ulcers in
neuropathic subjects were estimated at 32%
(21), and the incidence of
ulcers at the same or different sites in a foot with prior ulceration was
estimated at 50% over a period of 2-5 years
(22).
In two recent studies
(23,24),
the use of special shoes significantly decreased the incidence of new
ulcerations. The population considered in these studies was, however, an
outpatient population of neuropathic subjects, whereas our population mostly
comprised neuroischemic subjects hospitalized for severe foot ulcer.
All of our subjects had therapeutic shoes and received education on foot
care; their families also received education on foot care. Our patients also
received slippers with a rigid sole and thermoformable lining. The percent of
new ulcerations in our population was very low, and the period of time the
subjects were free from new ulceration was reasonably long.
The lack of significant association between new ulceration and the
investigated variables surprised us. We believe that some variables that we
did not record, such as social status, limited joint mobility, degree of
patient compliance regarding the continual use of the orthesis, and
educational learning
(25,26,27,28),
may play a role in episodes of new ulceration. We excluded alcoholism
(29), because none of our
patients consumed much alcohol. The lack of association with minor amputation
seems particularly interesting; we believe that this indicates the
effectiveness of orthesis, even in a deformed foot.
Available published data on ipsilateral and contralateral amputation is
discouraging. Reiber
(7,30)
reported that 13% of amputees in California and 9% in New Jersey would undergo
reamputation within a year of initial amputation, and he estimated that 30-50%
of the amputees would undergo contralateral limb amputation within 1-3 years
of initial amputation. In the 1980s, two studies
(8,9)
reported an incidence rate of contralateral amputation of 44.3% and
ipsilateral amputation of 23.1% after a 4-year follow-up and an incidence rate
of contralateral amputation of 26.4% after a 5-year follow-up.
Considering these data, we believe that the number of new ulcerations and
new major amputations in our follow-up was very low. We reached this goal by
providing instructions and education regarding orthesis to our patients
(31) and their families. It
seems that the use of therapeutic shoes is recommended
(32), but, to date, they are
not used much among diabetic patients
(33,34).
It should be emphasized that there is no difference in new ulceration between
patients monitored directly at our center and patients monitored infrequently
at distant locations. Therefore, undergoing an intense informational program
on admission to a hospital for ulceration and the fitting of therapeutic shoes
may reduce the number of new ulcerations, an independent risk factor for
amputation (35). Thus, we feel
that the American Diabetes Association
(36) should provide more
specific information on and a more assertive recommendation for the use of
therapeutic shoes for subjects with previous diabetic foot ulceration.
Because of the small number of new major amputations, we did not feel that
it was necessary to evaluate an eventual association with the variables in
question. However, we must specify that all three patients amputated in the
follow-up had an ABI <0.5 and could not be revascularized.
Our data lead us to conclude that the current epidemiological data on new
ulceration, new major amputation, and reamputation in diabetic subjects who
have undergone major amputation or who have recovered from a severe foot ulcer
are much more accurate than those previously reported. In these subjects,
major amputation only occurred in those with severe occlusive disease, when
revascularization was impossible.
The rate of survival in our amputees was similar to that found in other
published studies. Reiber (30)
reported a 39-68% mortality rate over a 5-year period. In the study by
Deerochanawong et al. (17),
the mortality rate was similar to ours, but the follow-up period was shorter.
In addition, Frykberg et al.
(12) reported a higher
mortality rate, but their subjects were much older. The data reported by
Rosemblum et al. (14)
presented a better outcome than previously reported data, but Rosemblum et al.
chose a population who had undergone vascular procedures under general
anesthetic, presumably with a low recurrence of ischemic cardiopathy. Survival
rates of our nonamputated subjects present a worse outcome than those reported
in a recent study by Ramsey et al.
(10), who analyzed the
survival of diabetic patients after ulcerative episodes, but during a very
short observation period. Furthermore, the presence of ischemic cardiopathy in
the Ramsey population (7%) was much lower than that in our study (47%), in
which it was the most frequent cause of death.
In addition, the protective value of smoking in our population was
particularly surprising. These results were contingent on the fact that the
women, who were older and had a higher mortality rate, were nonsmokers.
However, when sex and age were not considered, smoking lost its significant
association.
In conclusion, ischemic cardiopathy is the most frequent cause of death
among diabetic subjects with foot ulceration. These data are well documented
in nondiabetic and diabetic subjects with peripheral vascular disease
(37,38),
but little is known about diabetic subjects with foot ulceration who present
with ischemic cardiopathy. Therefore, we modified our protocol to adopt a more
aggressive diagnostic and therapeutic approach of ischemic cardiopathy in
diabetic subjects who were admitted to our hospital for foot ulceration.
