On 15 September 2015, the College of Pharmacists of British Columbia (BC) implemented a set of by-law and security policy changes in an effort to reduce robberies and burglaries in BC pharmacies. Prior to these by-law and security policy changes, pharmacy robberies were increasing in BC for approximately 5 years. After implementation, pharmacy robberies decreased significantly. In this paper, we evaluate the potential impact of the by-law and security policy changes on pharmacy robberies in four regions within BC. We find strong evidence supporting that the reduction in pharmacy robberies is a result of this by-law and accompanying security policy changes. Specifically, there was an immediate and substantial drop in pharmacy robberies within Vancouver, with a change in trend (now decreasing instead of increasing) for the Interior and Lower Mainland less Vancouver. These results should be considered support for maintaining these by-laws and security policy changes in BC and potential implementation in other areas of Canada experiencing similar issues.

对不列颠哥伦比亚省药房抢劫的法规和政策变化的评估

2015年9月15日，不列颠哥伦比亚省药剂师学院（BC）实施了一系列法规和安全政策更改，以减少BC药房中的抢劫和盗窃案。在这些法规和安全政策更改之前，卑诗省的药房抢劫案持续上升了大约5年。实施后，药房抢劫案明显减少。在本文中，我们评估了章程和安全政策变更对卑诗省四个地区药房抢劫的潜在影响。我们发现有力的证据支持减少药房抢劫是该法规和随之而来的安全政策变更的结果。具体来说，温哥华的药房抢劫案立即大量减少，内陆地区和低陆平原地区（温哥华地区）的趋势发生了变化（现在是下降而不是上升）。这些结果应被视为支持在卑诗省维持这些章程和安全政策的更改，以及在加拿大遇到类似问题的其他地区的潜在实施的支持。
