Sir,
We read this paper with interest.
1) The ASA scoring system as used in this study, though widely used,
has its limitations in determining the timing of early versus delayed
surgery as it does not reflect the severity of involved
systems, especially ASA grades 2 and 3 with which most of the elderly surgical patients
with hip fractures present.
We are of the opinion that the decision for early operative
intervention on an individual basis would be best represented by taking
into consideration the physiological reserves and the comorbid
conditions. The study by Dr JJ Roche et al has shown that age, male sex, and
the presence of three or more comorbidities on admission all predicted a
high risk of complications.1
2) The article has not shown an association with the time from
admission to surgery and mortality at either 30 or 120 days. This would be
a significant point of debate as most trials have shown at least an
improvement in short-term mortality rates of operating early in the elderly
population.
The meta-analysis study of Toshiya Shiga et al
showed that operative delay of more than 48 hours is associated with
increased short-term and mid-term mortality in elderly patients with hip
fracture but this did not correlate with the long-term mortality
studies (at one year) because chronic comorbidities progress in older
patients at high risk.2
At the same time it is imperative that in the elderly, the benefits
of operating early must be weighed with the pre-operative comorbid
conditions associated.
