Abstract

An ageing population with higher rates of helping seeking behaviour and treatment utilization is a worldwide phenomenon with no exception to Singapore. As elderly patients are fast becoming an increasing large part of our surgical practice, their long term outcomes are particularly important.

Objective: We take stock of our local experience in a high volume tertiary centre in Singapore, Tan Tock Seng Hospital by reviewing the number of surgical procedures performed for elderly patients (65 years old and above) across a decade and reviewing their post-operative outcomes.

Methods: This retrospective cohort study included elderly patients (>= aged 65) who underwent surgical procedures under general anaesthesia from January 2008 to December 2019. Demographic data, nature of operation, preoperative American Society of Anaesthesiologists (ASA) status of patients and surrogate markers of outcome including average length of stay (ALOS), 30 and 90-day mortality were retrospectively analysed.

Results: Across a 12-year period, we observed a nearly overall two-fold increase in the number of surgical procedures for elderly patients from 1,129 cases in 2008 to 2,118 cases in 2019. The ALOS for elderly surgical patients trended downwards from an average of 12.3 days in 2008 to 9.0 days in 2019. All cause 30-day mortality rate of elderly patients dropped from 5.8% in 2008 to 2.7% in 2019.

Conclusion: The landscape for general surgery in the elderly is changing in the context of advances in health care and a paradigm shift in treatment beliefs and perspectives. Ultimately, informed decision making, patient engagement and empowerment by the surgeon are keys to better outcomes and improved patient experience.
