To investigate the reasons that lead to postponement of cardiac operations, in order to elucidate the problem and help patients through modes of prevention.
We retrospectively included in the study all patients submitted to elective adult heart surgery in our department during the 4-year period 2007-2010 and noted all cases of postponement after official inclusion in the operating schedule.
94 out of a total of 575 patients (16.34%) scheduled for elective cardiac operation had their procedure postponed. The reasons were mainly organisatory (in 49 cases, 52.12%), which in order of significance were: unavailability in operating rooms, shortage in matching erythrocyte units and shortage in anaesthetic/nursing staff. The rest of the cases (45, 47.88%) were postponed due to medical reasons, which in order of significance were: febrile situations, including infections of the respiratory, gastrointestinal and urinary system, problems with the regulation of antiplatelet and antithrombotic drugs, neurological manifestations such as stroke and transient ischaemic attacks, exacerbation of asthma/chronic obstructive pulmonary disease, arrhythmias, renal problems and allergic reactions to drugs. Patients with advanced age and increased Euroscore values were most possible to have their heart operation postponed.
Heart operations are postponed due to organisatory as well as medical reasons, the latter mainly affecting older, morbid patients who therefore require advanced preoperative care.

Every physician employed in the practice of heart surgery is aware of the fact that the psychological condition of a heart patient scheduled for cardiac surgery is a very fragile one. Such patients have already been burdened with multiple examinations and hospital admissions and the vast majority of them suffers from a variety of other, non cardiac problems. In this setting, heart operation appears as a last great obstacle that can be overcome only if the remaining psychological resources of the patient are recruited. One can easily imagine the magnitude of stress such a patient experiences when his heart operation is postponed [1, 2].
In this study we are presenting the experience of our department on the matter during the last 4-year period by analyzing the reasons that led to the postponement of cardiac operations. Although organisatory reasons have also been taken into account, we have mainly focused on the medical conditions that are responsible for this postponement.
We retrospectively included in this epidemiologic analysis all patients scheduled and prepared for elective heart surgery in our department in the 4-year period 2007-2010, whose operation was postponed for any reason. We excluded patients with urgent operation who are entering the operating room even if not all required parameters of the preoperative preparation have been fulfilled and whose operation is practically never postponed. The aforementioned criteria led to the inclusion in the study of 575 out of a total of 728 heart patients (78.9%) operated in our department during the same period.
As far as the characteristics of our department are concerned: it is a cardiovascular and thoracic surgery department of a university tertiary care hospital, operating with European Union standards, covering with every-day 24-hour duty an area of responsibility of 1.3 million inhabitants. This explains some of the organisatory problems that arise in everyday practice.
Analysis of organisatory problems and medical conditions responsible for postponement of elective heart operations
Organisatory, n = 49 (51.57%)
Medical n = 45 (47.36%)
17 patients with febrile conditions (37.77%) (11 respiratory infection, 3 gastrointestinal infection, 3 urinary tract infection)
Unavailability in operating rooms 25 (51%)
13 patients (28.8%) with misinterpretation/incompliance of the patient with the medical order to discontinue antiplatelet/antithrombotic agents
Shortage in matching erythrocyte units 14 (28.57%)
4 patients (8.88%) with neurological manifestations, including one patient with stroke and three with TIA
Shortage in anaesthetic/nursing staff 10 (20.4%)
4 patients (8.88%) with exacerbation of asthma/chronic obstructive pulmonary disease
3 patients (6.67%) with cardiac manifestations (arrhythmias in form of atrial fibrillation) that required stabilization prior to surgery
two patients (4.44%) with increased blood urea/creatinine values during the last preoperative check, who were therefore scheduled for nephrological consultation
two patients (4.44%) with allergic reaction to recently administered drugs
Seven of the patients with postponement due to organisatory reasons had their operation postponed for the same reason for a second time. All of the patients who were postponed for medical conditions were operated with a delay ranging from 3 days for simpler conditions such as allergic reactions to 10 days for more grave conditions, such as persisting respiratory infections.

This study deals with the important issue of postponement of heart operations, a situation that causes both psychological burden for the patients as well as augmented hospitalization costs for any health system. To the best of our knowledge this is one of the few (three) of the kind in medical literature and the one based on the broadest sample. The study was conducted in a tertiary care university department with 24-hour/days emergency duty responsibility, a fact that can explain some of the organisatory problems encountered. The study concluded to the following results.
First of all, the majority of cardiac operations are postponed due to administrative/organisatory reasons. This makes, among other measures, imperative the need for better management and better use of resources for the sake of the patients, but also for reasons of financing and economy. The study referred to data from a period where both Greece as well as European Union faced serious financial recession, a fact that can cause augmented organisatory problems through lack cuts in expenses in infrastructure, material and employment of specialized personnel.
Attending physicians and nursing staff should be aware of the medical reasons that usually lead to the postponement of cardiac operations in an effort to avoid them: preooperative infections, especially of the respiratory system, wrong and prolonged used of antiplatelet/antithrombotic agents, neurological conditions, exacerbation of COPD and asthma, arrhythmias and allergic reactions to drugs are the most important.
These conditions most easily tend to affect old multimorbid patients, whose preoperative care should therefore be of the best possible quality. Hopefully and, against the difficulties of the global economic crisis, the organization of health units will allow in the future a better standard of care for cardiac patients scheduled for heart surgery, so as to avoid psychologically painful and economically burdening cases of operation postponement.
