Impact of educational programme on patient's health outcomes following open heart surgeries.

The study was done in one cardiovascular surgery unit in one area of Egypt, so it may not apply to other cardiac surgery patients or settings. There was no control group or random allocation, so changes cannot be separated from normal recovery after open-heart surgery, usual postoperative care, or other treatments. All patients received the educational programme plus surgery and usual care, so the contribution of any single component cannot be identified. The sample was 60 patients, and the paper does not report a clear primary outcome. The intervention is described inconsistently: two repeated sessions in one section and four 45-minute sessions in another. The follow-up timing is inconsistent, with 6 months mentioned in some outcome descriptions and 3 months in another. The data collection period is stated as August 2019 until February 2019, which is not a valid time range. Several reported conclusions do not match the tables, including the statement that all quality of life components improved except social despite some borderline or non-significant table values. The tools were adapted and translated for Arabic language and local culture, which may affect comparability, although reliability values were reported.

The paper reports no funding sources and no conflicts of interest.

Do not conclude that the educational programme caused the improvements. The study had no control group, and patients also received open-heart surgery, usual postoperative care, and the educational programme with booklets, so the effect of education cannot be separated from recovery and other care.
