Background
The purpose of this study was to evaluate the outcome of cardiac surgery at Allamanda Hospital which is a small private hospital carrying out less than 100 operations per year.Methods
Data on patients undergoing cardiac surgery since 2002 were prospectively entered into a database. An analysis of this data is presented and compared with national and international benchmarks for results from larger national and international cardiac surgery units.
Results
From October 2002 to March 2007, there were 360 patients who underwent cardiac surgery in a small private cardiothoracic surgical unit (average of 80 patients per year). The average logistic EuroSCORE, Cleveland Clinic and Parsonnet Scores for the patients were 13 % , 5.7 and 13.4, respectively. The mean logistic EuroSCORE observed in this study of 13 % was substantially higher than those of other published series and institutions. The Allamanda results were compared with those from the European database (EuroSCORE), the STS and the Victorian National Cardiac Surgery Database. The overall observed mortality at Allamanda of 7.5 % was lower than predicted by the mean logistic EuroSCORE of 13 % . In comparison with the Victorian database, there was no significant difference in mortality for low-risk (additive EuroSCORE 0–3) and medium-risk (4–6) groups. Patients in the high-risk group with additive EuroSCOREs ≥ 7 were similarly divided into categories of three additive EuroSCOREs. There was no significant difference in any of the categories in the high-risk group. There was a greater proportion of high-risk (additive EuroSCORE ≥ 7) patients in the Allamanda series (P < 0.0001). Patients in the Allamanda series were older (mean age 70.1) than the other published series (P < 0.0001). The mean logistic EuroSCORE for the mortality group was 35.9 ± 29.4 % (6.4–65.3 % ).
Conclusion
Low volume cardiac surgery can be undertaken safely in a small Australian private cardiothoracic unit with acceptable results. The trend towards improved outcomes for high-risk patients in larger institutions suggests that such patients undergoing elective procedures should be given the option of doing so in a larger centre. Ongoing quality assurance programs are equally important for large and small cardiac surgical units with participation in a national or international cardiac surgery database.
