Implementation of clinical pharmacy services in an academic oncology practice in India

Objective This study was conducted to investigate medication-related problems after implementation of clinical pharmacy services at a speciality oncology care setting. Methods It was a prospective interventional study conducted for a period of three years at a private academic oncology care setting. Paper-based medical records and medication orders were reviewed and patients and care givers were interviewed to understand the treatment plan. All the medication-related problems were identified by clinical pharmacists by performing drug therapy review. Patients were also followed up at ambulatory care and in-patient units to ensure appropriate administration of anti-cancer drugs by nurses. All the medication-related problems were discussed with the concerned clinicians and then were resolved with the interventions of clinical pharmacists. Clinical significance of these interventions were assessed and classified as "Major", "Moderate "and "Minor". Educational, clinical and system-based interventions were developed and implemented to minimize medication-related problems at the study site. Results A total of 1359 medication-related problems were identified from 2120 medication orders reviewed of 1362 patients followed during the study period. The most common medication-related problems were lack of suboptimal supportive care (17.95%), inappropriate administration of medications (14.56%), untreated indication (14.20%), wrong dosing calculations (12.21%), drug-drug interactions (11.62%) and sub-therapeutic dose (11.11%). Clinical pharmacy interventions were made to resolve all the medication-related problems. Clinical significance of majority (n = 504, 37.08%) of medication-related problems was "Moderate" followed by "Major" (n = 434, 31.93%) and "Minor" (n = 421, 30.97%). Conclusion The study has demonstrated the importance of clinical pharmacy services in improving quality and safe use of medicines in oncology practice. Positive feedback of clinicians on clinical pharmacy services was a reflection of acceptance of clinical pharmacy interventions by clinicians.
