Perioperative medication therapy for Muslim patients in Germany undergoing oncological surgery: a retrospective study

Engagement of healthcare professionals with patients from diverse cultural and religious backgrounds is crucial in our multicultural society, where miscommunication and errors in medical history taking can lead to incorrect treatment. In particular, Muslim patients may present unique considerations due to their specific cultural and religious beliefs, which can significantly impact treatment outcomes. This study focuses on perioperative medication therapy for patients undergoing upper and lower gastrointestinal tract and pancreatic tumor surgery, specifically examining whether Islamic beliefs were duly considered in medication selection compared to a matching patient cohort.

Data from January 2004 to July 2023 were analyzed. Muslim patients were identified using the onomastic method and matched with non-Muslim patients at a 1:3 ratio based on age, gender, and procedure. Analysis included examination of subcutaneous, oral, and intravenous medications, with attention to ingredients and compatibility with Islamic principles.

Among 5272 patients, only 5 met the study's inclusion criteria as Muslim patients, undergoing procedures such as anterior rectum resection, gastrectomy, and pancreatic head resection. Their religious affiliations were not documented in the admission records. According to the matched-pair analysis, consistent treatment was performed regardless of religious beliefs. All patients received subcutaneous medication, primarily enoxaparin, instead of fondaparinux, an Islam-compliant alternative. Intravenous heparin was used once for short period. Contrary to Islamic dietary restrictions and the availability of alternatives, capsules containing animal-derived gelatin and other non-compliant medications were administered orally.

This study underscores the importance of acknowledging Muslim patients' cultural and religious backgrounds in the perioperative setting, as failure to do so may lead healthcare professionals to overlook their potential alternative medication needs, which are essential for providing tailored medical care in modern societies. Integration of diversity-related topics into medical curricula is essential for better preparing physicians for clinical practice and ensuring patient-centered care.
