Objective To study the effectiveness of zolpidem and sleep hygiene counseling in managing insomnia in solid tumor patients. Methods Cancer patients with a Pittsburgh Sleep Quality Index score ≥ 5 were grouped into two. Both groups received treatment for insomnia in the form of either zolpidem 5 mg for 7 days or sleep hygiene counseling. Result At baseline, zolpidem and counseling group had a mean Pittsburgh Sleep Quality Index score of 14.82 ± 2.61 and 11.67 ± 3.32, respectively. The difference in mean Pittsburgh Sleep Quality Index score was found to be 4.03 in patients using zolpidem and 1.5 in counseled patients (p = 0.003). The components of Pittsburgh Sleep Quality Index namely difficulty falling asleep within 30 min (sleep latency), overall sleep quality, trouble staying awake during daytime and trouble staying motivated to get things done showed statistically significant improvement after treatment with zolpidem. Following sleep hygiene counseling, the proportion of patients with sleep latency > 30 min reduced considerably. Waking up to use the bathroom was the most common problem reported by approximately 94% patients in both groups before treatment which remained the most prevalent problem even after treatment. Night or early morning awakenings seemed to decrease significantly in patients taking zolpidem (p = 0.039) while it did not show any improvement with counseling. Counseling seemed to get patients to sleep within 30 min. Conclusion Patients on zolpidem showed a reduction in their Pittsburgh Sleep Quality Index scores thereby suggesting it as a treatment for insomnia in solid tumor patients. Sleep hygiene counseling, though not as effective as zolpidem, made a slight difference in the overall sleep.
Background: Patients undergoing solid organ transplantation are at a higher risk of multi-drug resistant (MDR) bacterial infections especially during the immediate post operative period. Objective: To audit the usage, dosage appropriateness and safety of colistin use in abdominal solid organ transplant recipients to treat immediate post-transplant bacterial infections. Methods: After completion of 1000 abdominal solid organ transplants at our institute, data of the transplant recipients who received colistin between October 2010 and December 2019 was extracted from the hospital health information system. Data of all microbiological culture isolates, the minimum inhibitory concentration (MIC) of colistin, appropriateness of colistin dosing and nephrotoxicity associated with colistin use was assessed. Results: Of the 1170 (732 liver and 438 renal) solid organ transplant recipients, 82 (66 liver and 16 renal) received colistin to treat posttransplant MDR bacterial infections. Nearly 60% received colistin as definitive therapy and 87.81% received colistin as combination. Mean duration of colistin therapy was found to be higher in renal than liver transplant recipients. Out of the total 89 bacterial isolates, there were 2 colistin resistant Klebsiella strains. Colistin in combination with meropenem (36.4%) was the most commonly used dual therapy. Out of the total 89 bacterial isolates, there were 2 colistin resistant Klebsiella strains. Overall in-hospital mortality of patients who received colistin was 43.9%. Renal impairment occurred in 28.8% of liver transplant recipients. Conclusion: Infection necessitating colistin use increases mortality by three folds in liver transplant recipients and by five percentage points in renal transplant recipients.
