a stroke as a third major complication. None of these 17 (1.0%)
patients died. Their median BMI was 29.4 kg/m
2
and those with
intact sternums had a BMI of 28.4 kg/m
2
.
The presence of COPD was found in 29% of patients with
sternal dehiscence compared with 12% among those with a
sternum in one piece. In a large Finnish study, 70% of patients
with deep sternal sepsis were taken to theatre. This represents a
prevalence of 0.8%.
39
Patients are under the impression that the
chest bone does not heal. A South African study investigated the
general picture of post-CABG patients after six weeks and found
six patients of 179 with no healing of the chest bone. Two of them
had already had a second attempt in hospital to approximate the
sternum.
40
At least three others had risk factors such as prolonged
mechanical ventilation and heart failure with pneumonia.
Most patients in our series were not from Bloemfontein,
where the operation was done. They had to be well enough to
travel back to whence they came, where health facilities are often
limited. In general, patients are discharged only when the risk
of re-admission is low. According to the STS registry, 51.2%
of patients had an LOS of less than six days and 5.6% were
hospitalised for more than two weeks.
22
As far as isolated CABG
is concerned, the hospital LOS compared well with the STS.
Limitations
Larger numbers have more statistical power, but smaller numbers
are the reality of a typical South African cardiac unit. In the
private sector one finds units with a single surgeon and many
with only a few surgeons per unit. Although the surgeon used
transparent definitions, there was still a personal interpretation.
The additive EuroSCORE was used but this probably
underestimated the real mortality risk. The logistic EuroSCORE
was perhaps more accurate for the higher-risk patient, especially
in a low-volume practice.
41
It has been stated before that 26.3%
of patients fell into a higher-risk category. Low-risk patients did
very well, with an O/E of
<
0.61 and even less.
To determine a unit’s care of patients withmajor complications
is a good way of assessing performance. The fewer the number of
patients that die with a major complication, the better the unit
performs. Those are the patients who failed to be rescued (FTR).
A Canadian unit reported on 5 000 various open cardiac surgical
cases over five years,
42
where the mortality rate was 3.6%. Ten
important complications were associated with 92% of the deaths.
Their calculated FTR was 19.8%. In other words, in spite of
major complications, 80.2% of patients survived. A FTR for the
Tabula viva chirurgi
would have been a good indication of how
Mediclinic, Bloemfontein, fares as far as the care of patients with
major complications is concerned, but we lacked data for this to
be calculated. Table 8 might give some indication of the outcome
of the patients with one or more of the five major complications.
Of the patients with one or more major complications, 25% died.
Conclusion
It was not the intention to present these data as a benchmark for
the South African context, but it opens a window on a private
cardio-surgical practice in South Africa. The outcomes are in
line with those of established units and databases all over the
world. This is wisdom related to the scientific and technical
aspects associated with cardiac surgery and care. These findings
also bring a new wisdom to the fore, which allows the surgeon to
move from loneliness to solitude as a spiritual movement. The
disappointments of negative surgical outcomes should move on to
make the surgeon’s responsibilities a vocation instead of a burden.
This allows the surgeon to provide hospitality as an alternative to
hostility towards the patient.
18
Such a spiritual experience should
also have spiritual transformation as an outcome.
43
As part of
creation, physiological limits exist and surgical outcome is based
on these limits. Mortality and morbidity are time and again
linked to co-morbidity and surgical risk. This has implications for
the pastoral and spiritual care of the sick.
