Objective: There are only a few studies evaluating the effects of drug information services on pharmacotherapy.  We, therefore, studied the effects of providing drug information such as the effectiveness and safety of aliskiren on its pharmacotherapeutic efficacy by comparing before versus after drug information provision.
Methods: Pharmacists provided drug information such as the effectiveness and safety of aliskiren coadministered with either ACE-I (angiotensin converting enzyme inhibitor) or ARB (angiotensin receptor blocker) to physicians and other healthcare professionals.  We compared the number of patients for whom aliskiren was prescribed, the proportion of diabetic patients taking both aliskiren and ACE-I (or ARB), the proportion of patients with low eGFR (estimated glomerular filtration rate), and the proportion of patients with hyperkalemia and related conditions, before versus after providing the drug information to the healthcare professionals.
Results: The number of patients for whom aliskiren was prescribed decreased.  The proportion of patients taking both aliskiren and ACE-I (or ARB) decreased significantly after providing the drug information (p=0.007).  The proportion of diabetic patients taking both aliskiren and ACE-I (or ARB), the proportion of patients with low eGFR, and the proportion of patients with hyperkalemia also decreased, after providing the drug information.
Conclusion: This study showed the drug information service to be clinically beneficial, achieving better pharmacotherapy.  Pharmacists should evaluate and provide information on the effectiveness and safety of drugs announced by authorities in a timely manner to achieve optimal patient care.

This study sought to demonstrate the benefits of conducting cervical cytology and human papillomavirus (HPV) testing in our cervical cancer screening program and was conducted between April 2012 and March 2017 in the Yuri-Honjo district of Akita Prefecture. A total of 3581 women aged 20-49 years underwent this combined screening for 5 years. Of these, 10.3% (369/3581) tested positive for HPV, and 433 women were initially diagnosed as positive for atypical squamous cells of undetermined significance and/or positive for HPV. Of those, 342 women (79.0%) underwent cervical biopsy, among whom 62 (18.1%) were diagnosed as positive for cervical intraepithelial neoplasia (CIN)2+. Of 204 women who were positive for HPV but showed no abnormalities in cytology, 24 women (11.8%) were positive for CIN2+ and 6 women were positive for CIN3+. Conventional cytology (Pap test) detected only 0.58% of the examinees positive for CIN2+ in Akita Prefecture, whereas our combined screening involving a Pap test and HPV testing detected 1.73% of the examinees (P<0.0001). We recommend HPV testing be used in combination with the Pap test to improve cervical cancer screening and accurately identify CIN2/3 disease.
