This study aims to emphasize the role of clinical pharmacists in evaluating the DTP’s frequencies, causes, severity ratings, and contributing factors at a general surgery ward in Jordan.Methods: This prospective observational study was conducted at one of the major teaching and referral hospitals in Jordan. Data were collected through clinical pharmacist reviews of paper and electronic medical records as well as patient interviews. DTPs were identified using Cipolle’s classification system and rated for severity on a scale of 10. Multiple linear regression was performed to identify factors contributing to DTPs. Drug classes primarily associated with DTPs were specified.Results: During enrollment, a total of 80 patients were recruited in this study. The mean age of the enrolled patients was 52.35 ± 14.82 years, and 49 (61.25%) of them were males. Within the study period, 192 DTPs were identified by clinical pharmacists in 87.5%of the total recruited patients. The mean number of DTPs per patient was 2.40 ± 1.83. The most common categories of DTPs were “needs additional therapy” 46 (23.96%), “unnecessary drug therapy” 45 (23.44%), and “dosage too low” 39 (20.31%). Of the total DTPs, 127 (66.15%) were rated as severe. Multiple linear regression revealed that patients’ length of hospital stay and the number of current medications had a statistically significant effect on the number of DTPs identified during hospitalization. Endocrine and metabolic drugs 51 (26.56%) and cardiovascular drugs 36 (18.75%) were the most frequent classes of drugs contributing to DTPs.Conclusion: DTPs are common in the general surgery ward. Clinical pharmacists can provide medication reviews for surgical patients to identify DTPs and rate their severities. Detecting risk factors for DTPs and the most common drug classes associated with them can assist in decision-making relevant to reducing DTPs in the surgical ward.Keywords: drug therapy problems, clinical pharmacist, surgery ward, observational study
