Polypharmacy and comorbidity status in the treatment of type 2 diabetic patients attending a tertiary care hospital: An observational and questionnaire-based study.

Purpose/aim: Diabetes mellitus is associated with several comorbid conditions. Thus, often, diabetic patients are prescribed multiple drugs. Although multiple drugs help to combat various diseases, they also increase the propensity of drug interactions and adverse drug reactions. The present study thus tried to evaluate the comorbid conditions and concurrent medications associated with type 2 diabetic patients. It also aimed to address patient compliance for the medications provided to them.

Materials And Methods: This was a cross-sectional observational study conducted for 2 months - January-February 2017. Data were collected from prescriptions of the patients and also by interviewing the willing patients, attending the Diabetic Clinic of R. G. Kar Medical College, Kolkata, India.

Results: During the study period, 150 patients were interviewed and their prescriptions were studied. Out of 150 patients, 69 (46%) were males and 81 (54%) were females. The mean age of the study population was 51.5 (±0.78) years. The present study evaluated that 83.3% (125) of the study population suffered from at least one comorbid conditions, the most common being hyperlipidemia (70.7%) and hypertension (47.3%). The average number of drugs prescribed is 4.72 (±0.11) per prescription. Metformin was prescribed to 96% of the patients. The concurrent medications recommended included hypolipidemics (72%), antihypertensives (68%), drugs for peptic ulcer (34.7%), and antiplatelets (10.7%).

Conclusion: The present study thus concluded that diabetic patients suffer from a number of comorbid conditions, most commonly, cardiovascular problems. The comorbidity increased with the age. The level of polypharmacy was also high, thereby increasing the pill burden for the patients.
