Polypharmacy is the most frequent cause of drug-induced side effects. It is very common in the elderly patients suffering from different chronic diseases. Side effects increase the rate of hospitalizations and mortality. START (Screening Tool to Alert doctors to Right Treatment)/STOPP (Screening Tool for Older Persons' Prescriptions) criteria were developed in 2008 and updated in 2015 for audit of prescriptions in the elderly patients.
