2RESEARCH METHODS AND EVIDENCE BASED PRACTICE
Introduction
The topic presents brief explanation about the preventive alcohol checks and its impacts
on the people who drive vehicles after drinking. Based on the evidences related to the increased
numbers of accidents in the past few years, the major cause had been drinking and driving. The
topic will illustrate about the various aspects related to the control checks’ impact on the people
who drive after drinking. The various questions will be assessed to understand the treatment
groups selected randomly along with the impact of control checks integrated for ensuring that the
occurrence of accidents decrease and the traffic is managed properly (Palinkas et al. 2015).
Background
The background of the research demonstrates the accidents that have been occurring for
the past few years as people drive their cars after consuming alcohol. It has been a major
problem, not only for the traffic but also the accidents take the lives of many people. It is
important to shed light on the fact that the groups who are affected the most due to this issue are
the individuals who consume alcohol and drive their cars. The preventive alcohol checks can
ensure that the police stop the cars and check whether they have consumed alcohol or not
(Bryman and Bell 2015). In case they are drunk, they should be penalized or even given some
kind of punishment so that the same thing does not happen again and the occurrence of accidents
are reduced to a large extent.

3RESEARCH METHODS AND EVIDENCE BASED PRACTICE
Critical appraisal criteria
1. Yes, the assignment to the treatment groups are truly random and it is quite clear that the
random selection of candidates has helped in understanding that driving after having drinks is
one of the major causes of accidents. According to the random selection and treatment of groups,
it is also found that the drinking driving has contributed to the large proportion of the traffic
accidents. The effects of alcohol on drivers are immense and it affects the driving performance
too (Ritchie et al. 2013). The assignment to treatment groups on a random manner helped in
collecting data and information related to the subjective feelings and driving performance in
different blood alcohol concentration levels. Not only the consumption of alcohol affects the
behaviors of individuals, but also their perception, reaction and controlling the vehicles tend to
change, which has increased the higher rate of accidents. It was not only considered as a major
threat to traffic safety but also created issues while driving the vehicles (Meesmann, Martensen
and Dupont 2015).
2. The participants were not blinded to treatment allocation, because they should be informed
about the causes of accidents and even the outcomes that might be generated while driving after
drinking. The allocation of treatment procedures could not only reduce the occurrence of
accidents, but also would enable conducting the preventive alcohol checks so that people can
stop to drive after drinking. It was found that the consumption of alcohol impaired the driving
skills and increases the chances or risks of accidents, which could cause serious injuries and even
sometimes death. The alcohol impaired driving accidents contribute to large numbers of deaths
of people as well as animals like kangaroos in Australia. It is approximately 30 percent of the
traffic fatalities in Australia (Erickson et al. 2013).
