New Study: Anti-Fatigue Training Yields Big Benefits For Officers

Print Friendly, PDF & Email

Can just four hours of instruction on sleep problems and improvement help tired cops face the job with significantly less fatigue?

Results of a recently published pilot study with the Royal Canadian Mounted Police suggest that’s possible.

In a first-of-its-kind test, researchers headed by Dr. Lois James of Washington State U. in Spokane have found that simple, straightforward fatigue-management information packaged for police can not only increase sleep quality and satisfaction but can also have a positive impact on rest-related mental and physical health as well.

“Any anti-fatigue program that works is literally a lifesaver,” says Dr. Bill Lewinski, executive director of the Force Science Institute, which was not involved in this study. “Fatigue from sleep deprivation robs officers not only of a sense of personal wellbeing but also profoundly affects the cognitive abilities vital to their survival—alertness, decision-making, resilience from stress. So when we talk about counter-fatigue measures, we’re talking potentially about life-or-death implications.”

Zzzzzzzzz PROBLEMS

The volunteer participants in James’ study were 61 employees of the RCMP in the province of Saskatchewan, white male constables (frontline patrol officers) predominately, with some sworn personnel of higher rank and a few civilians included. They averaged 11 years in law enforcement, served in both rural and urban jurisdictions, generally were married or in a domestic partnership with kids living at home, tended to work eight- or nine-hour rotating shifts plus overtime, and were often on call even when off-duty. Average age was 38.

Their responses to an anonymous, self-reporting questionnaire surfaced sleep patterns and problems common among cops.

  • Although the majority reported their “quality of life” as being good or very good overall, only 21% were “satisfied” with their sleep.
  •  Close to half (45%) suffered from insomnia, with 14% claiming their sleep was disrupted by sleep apnea.
  •  On average, they got about six hours’ sleep per 24-hour period, but that number jumped to nearly eight hours during non-working periods. This suggests they were trying to “catch up” from “insufficient sleep quality,” a strategy that’s ineffective, according to the researchers. Indeed, 70% reported being routinely “bothered by tiredness/fatigue.”
  •  There were prolific reports of mood disorders: 20% were bothered by depression; 26% by anxiety; 16% by what they felt was PTSD; 12% by “frequent temper outbursts”; 32%, 55%, and 63% respectively were “distressed” by feeling “hopeless,” “blue,” or “tense” on a regular basis.
  •  In the realm of physical health, the majority (59%) were generally satisfied with their status, but over half reported “routinely” suffering from headaches and 41%—an “alarming” number, in the researchers’ view—complained of “neck/back/spine trouble.” This data provided baseline measurements for the study and overall reflected “considerable sleep, health, and wellness problems,” James writes.

KNOWLEDGE Rx

Members of the RCMP’s Fitness and Lifestyle Unit were trained by the research team to, in turn, educate the study’s participants on sleep health and wellness.

Across three to four hours of instruction, the RCMP trainers exposed the participants in small groups of five to 10 to a copyrighted anti-fatigue program that had earlier been developed for the Calgary (Alberta) Police Service by one of James’ research team, Dr. Charles Samuels.

Samuels, a physician on the medical faculty of the University of Calgary, is the medical director of the Centre for Sleep & Human Performance, a prominent Canadian sleep lab and testing facility.

The program informed participants in four areas:

  1.  The science of sleep
  2.  Sleep disorders
  3.  Sleep apnea, and
  4.  Fatigue countermeasures.

The latter, says James, included how-to instruction on topics such as strategic napping, caffeine management, improvement of sleep hygiene, light therapy, and hydration.

Samuels adds, in an email to Force Science News: “Strategic napping and the strategic use of caffeine for improved alertness are the cornerstone of fatigue countermeasures. There is substantial human research and evidence to support the idea of consuming caffeine either before or after a 30-minute nap prior to a night shift. This countermeasure can improve alertness on night shift and potentially mitigate fatigue-related human-performance errors.”

In the training course, James writes, participants learned about “basic sleep needs, how to identify symptoms of sleep disorders, how to get screened for sleep disorders, and how to combat fatigue and improve sleep hygiene on a day-to-day basis.” The training was interactive, with “open discussion about sleep-related questions and concerns,” and included a PowerPoint presentation “with videos of case studies.”

RETESTING & RESULTS

Four weeks after completing the educational session, the participants were retested with the same comprehensive questionnaire they’d filled out before the training. The results, James notes, showed “many positive health benefits.”

For instance:

  • The number of participants reporting satisfaction with their sleep quality nearly doubled.
  •  Those complaining of insomnia dropped from nearly half of the pool to less than one-third.
  •  The number feeling symptoms of PTSD was cut in half.
  •  Those suffering routinely from headaches declined from 51% to 27%, while those reporting neck/back/spine trouble went from 41% to 26%.

Marked improvement was noted in the adverse mood categories, and more participants reported feeling “satisfied” overall with their physical health.

In commenting on the training, the participants “were very positive,” James reports. One explained: “It’s really helped me and [my spouse] and has made a huge difference in our life. One of the things I took from it the most is that you have to be selfish about your sleep. You have to make it a priority. I’ve been sleeping a lot more….”

IMPLICATIONS

“Our findings suggest that fatigue-management training holds promise for improving police sleep, health, and wellness, and would be culturally accepted by police officers if implemented elsewhere,” James writes.

Among the policy considerations arising from the study, she believes, are “the creation of ‘restorative rest areas’ for strategic napping, development of a managers’ tool kit to guide supervisors in better supporting members who are chronically fatigued, increased awareness of the importance of monitoring employee work hours, and provision of sleep screening resources.”

Dr. Samuels told FSN that the study results have “motivated the RCMP senior management to continue the fatigue-management project on a larger scale, through its Fitness and Lifestyle Division.”

Correcting sleep deprivation among LEOs is an urgent problem with critical implications that cannot just be “willed away,” James argues. She quotes the pioneering sleep researcher Dr. William Dement:

“Not only is fatigue associated with individual misery, but it can also lead to counterproductive behavior. It is well known that impulsiveness, aggression, irritability, and angry outbursts are associated with sleep deprivation….

“[P]olice work is the one profession in which we would want all practitioners to have adequate and healthful sleep to perform their duties at peak alertness levels.”
