In occupational health, mental health measures in the workplace are classified into three categories: primary, secondary, and tertiary prevention of mental health problems. The tertiary prevention aims to provide appropriate support for the return to work of workers who have been absent from work for a long period of time, prevent recurrence or relapse of the illness, and promote readjustment to the workplace. However, there have been some problems in determining whether or not to provide such support. Rework programs are now being implemented at medical facilities. These programs are mainly for workers who have depression or are in a depressed state; however, it has been recently pointed out that symptoms of depression are becoming more diverse and the developmental characteristics of users should be paid attention to. Our hospital opened a rework daycare center in November 2007 and has been supporting, in collaboration with their attending physicians and workplace, the return to work of those who have taken a leave of absence. This study reviews those efforts to date and discusses future issues to be addressed.

Introduction: In some cases, anticancer drugs are wasted for various reasons after preparation, resulting in an economic burden. Therefore, the pharmacists in the study verified laboratory test values before dispensing the drug and determined the financial effect of reusing the wasted drug for other patients.

Methods: This study collected data from our electronic medical records of 46 of 17,042 cases prescribed with intravenous chemotherapy drugs between March 2021 and February 2023. The number, rate, and costs of wasted drugs were investigated between groups A (n = 18) and B (n = 28) for the year before and after the pharmacists' intervention.

Results: The wasted drug rate after preparation was 0.21% in group A and 0.33% in group B, with no significant difference between the two groups (p = 0.184). In group B, wasted drugs due to pharmacist-checked items were significantly lower (p < 0.001).

There was no significant difference in the cost of wasted drugs between the two groups (p = 0.628). However, the final wasted drug cost, excluding those avoided by using reused drugs, was lower in group B (p = 0.067).

Conclusions: If pharmacists verify laboratory test values and reuse drugs after discontinuation, it may decrease economic losses and ensure safe administration by reducing waste due to medical worker factors.
