Brief Summary

Type 2 diabetes mellitus (T2DM) poses a significant burden on the patients and the health care system. The increasing number of surgery performed in elderly population results in an increased number of perioperative T2DM-related adverse effects. T2DM has a prevalence of 30-40% in a population undergoing cardiovascular surgery. Cardiac surgery, especially cardiopulmonary bypass (CPB) is also known to deteriorate respiratory mechanics. Therefore, the study is aimed at a retrospective analysis of seasonal trends in respiratory consequences of T2DM, i.e.: i: distribution of patients with and without T2DM presenting for elective cardiac surgery during the two-year examination period; ii: characterization of respiratory co-morbidities in the patients, iii: exploring whether the respiratory mechanics at presentation and those caused by cardiac surgery exhibit different trends in T2DM and control patients.

Outcome Measures

Primary Outcomes (4)

  • Seasonal variation in the incidence of diabetic patients undergoing cardiac surgery

    All patient data from the time period 2006-2018 will be retrospectively analysed to explore the seasonal trends of diabetic patients (Type 1 and Type 2) undergoing cardiac surgery at a university hospital setting. The relative incidence of diabetic patients will be evaluated on a monthly basis in the study period.

    Retrospective data analysis (2006-2018)

  • Anthropometric data of patients undergoing cardiac surgery

    All patient data from the time period 2006-2018 will be retrospectively analysed to explore the seasonal trends of diabetic patients (Type 1 and Type 2) undergoing cardiac surgery at a university hospital setting. Anthropometric data will be collected from the patient records: height (meters) and weight (kilograms) of each patient will be collected from the hospital medical records, then these data will be combined to report BMI (kg/m\^2).

    Retrospective data analysis (2006-2018)

  • Comorbidities of diabetic patients undergoing cardiac surgery

    All patient data from the time period 2006-2018 will be retrospectively analysed to explore the seasonal trends of diabetic patients (Type 1 and Type 2) undergoing cardiac surgery at a university hospital setting. Co-morbidities (COPD, asthma, hypertension, etc.) of each patient will be collected from the hospital medical records.

    Retrospective data analysis (2006-2018)

  • Smoking habits of patients undergoing cardiac surgery

    All patient data from the time period 2006-2018 will be retrospectively analysed to explore the seasonal trends of diabetic patients (Type 1 and Type 2) undergoing cardiac surgery at a university hospital setting. Reported smoking habits (present smoker/previous smoker/never smoker; number of packs / day; duration) of each patient will be collected from the hospital medical records.

    Retrospective data analysis (2006-2018)
