Patterns of drug therapy, glycemic control, and predictors of escalation - non-escalation of treatment among diabetes outpatients at a tertiary care center.

OBJECTIVES: The study was conducted to assess patterns of prescribed drug therapy and clinical predictors of need for therapy escalation in outpatients with diabetes mellitus (DM). METHODS: This was a prospective cohort study, conducted at an apex tertiary care teaching hospital in central India for a period of 18 months. The demographic, clinical, and treatment details on the baseline and follow up visits were collected from the patients' prescription charts. Glycemic control, adherence, pill burdens along with pattern of antidiabetic therapy escalation, and deescalations were analyzed. RESULTS: A total of 1,711 prescriptions of 925 patients of diabetes with a mean age of 53.81 ± 10.42 years and duration of disease of 9.15 ± 6.3 years were analyzed. Approximately half of the patients (n=450) came for ≥1 follow up visits. Hypertension (59.35%) was the most common comorbidity followed by dyslipidemia and hypothyroidism. The mean total daily drugs and pills per prescription were 4.03 ± 1.71 and 4.17 ± 1.38, respectively. Metformin (30.42%) followed by sulphonylureas (SUs) (21.39%) constituted majority of the AHA's and dual and triple drug therapy regimens were most commonly prescribed. There were improvements in HbA1c, fasting/postprandial/random blood sugar (FBS/PPBS/RBS) as well as adherence to medication, diet, and exercise in the follow up visits. Among patients with follow ups, therapy escalations were found in 31.11% patients, among whom dose was increased in 12.44% and drug was added in 17.28%. Apart from Hb1Ac, FBS, and PPBS levels (p<0.001), characteristics such as age, BMI, duration of diagnosed diabetes, presence of hypertension and dyslipidemia, and daily pill burdens were found to be significantly higher in the therapy escalation group (p<0.05). Inadequate medication adherence increased the relative risk (RR) of therapy escalation by almost two times. CONCLUSIONS: Disease and therapy patterns are reflective of diabetes care as expected at a tertiary care center. Higher BMI, age, pill burden, duration of diabetes, presence of comorbidities, and poor medication adherence may be the predictors of therapy escalation independent of glycemic control and such patients should be more closely monitored.

Evaluation of an outpatient department (OPD)-based prescribing pattern of fixed-dose combinations in a tertiary care institute in Central India.

Background Fixed-dose combinations (FDCs) are being widely prescribed for the treatment of various disorders in India. However, not all FDCs are rational. To know the awareness of physicians in prescribing rational FDCs was the need of the hour in order to assess the prescribing trends and rationality of FDCs. Eventually, this will help to formulate the guideline for rational use of FDCs. Methods This was a prospective observational study conducted in All India Institute of Medical Sciences Bhopal, MP, India. Prescriptions were collected over a period of 2 months by the convenience sampling method from hospital pharmacy. The data were subjected to descriptive analysis using Microsoft Excel and Graph Pad Prism. Results were expressed in mean ± standard deviation (SD), percentages and 95% confidence interval. Results A total of 2496 drugs were prescribed in 1008 prescriptions, of which 945 (37.82%) were FDCs with an average of 0.93 ± 0.94 (mean ± SD) per prescription. Of 945, 67 (7.09%) were included in National List of Essential Medicine 2015 considered as rational. The number of prescriptions containing one or more FDCs was 629 (62.40%). FDCs were more frequently prescribed to male patients (54.92%) and in the age group of 18-30 years (33.44%). FDCs containing a proton pump inhibitor were prescribed most frequently (16.29%) followed by nonsteroidal anti-inflammatory drugs (13.96%) and multivitamins (7.83%). Conclusions Prescribing irrational FDCs was very common, and hence there is an obvious need to update our prescribers about the irrationality of FDC and motivate them to develop a habit of rational prescribing.
