Restricting access to alcohol and public health: Evidence from electoral dry laws in Brazil

Vitreoretinal surgical performance after acute alcohol consumption and hangover

AIM

Routine alcohol testing of practicing physicians remains controversial since there are no uniform guidelines or legal regulations in the medical field. Our aim was to quantitatively study the acute and next-morning effects of breath alcohol concentration (BAC)-adjusted alcohol intake on overall simulated surgical performance and microtremor among senior vitreoretinal surgeons.

METHODS

This prospective cohort study included 11 vitreoretinal surgeons (>10 years practice). Surgical performance was first assessed using the Eyesi surgical simulator following same-day alcohol consumption producing a BAC reading of 0.06%-0.10% (low-dose), followed by 0.11%-0.15% (high-dose). Dexterity was then evaluated after a 'night out' producing a high-dose BAC combined with a night's sleep. Changes in the total score (0-700, worst-best) and tremor (0-100, best-worst) were measured.

RESULTS

Surgeon performance declined after high-dose alcohol compared with low-dose alcohol (-8.60±10.77 vs -1.21±7.71, p=0.04, respectively). The performance during hangover was similar to low-dose alcohol (-1.76±14.47 vs -1.21±7.71, p=1.00, respectively). The performance during hangover tended to be better than after high-dose alcohol (-1.76±14.47 vs -8.60±10.77, p=0.09, respectively). Tremor increased during hangover compared with low-dose alcohol (7.33±21.65 vs -10.31±10.73, p=0.03, respectively). A trend toward greater tremor during hangover occurred compared with high-dose alcohol (7.33±21.65 vs -4.12±17.17, p=0.08, respectively).

CONCLUSION

Alcohol-related decline in simulated surgical dexterity among senior vitreoretinal surgeons was dose-dependent. Dexterity improved the following morning but remained comparable to after low-dose alcohol ingestion. Tremor increased during hangover compared with same-day intoxication. Further studies are needed to investigate extrapolations of these data to a real surgical environment regarding patient safety and surgeon performance.

The effect of alcohol sales restrictions on alcohol poisoning mortality: Evidence from Russia

This paper examines the tough anti-alcohol legislation recently introduced in Russia, which due to regional variation allows it to be used as a natural experiment. The effect of the restricted trading hours on alcoholic poisoning mortality is estimated. To establish a causal link, difference-in-differences and synthetic controls are used. The main conclusion is that the sales restrictions lead to higher alcohol poisoning mortality, which implies that more toxic alcohol surrogates serve as substitutes for commercially available alcohol.

Election bans and alcohol banes: The impact of elections on treatment referrals at a tertiary addiction treatment facility in India

Pattern of alcohol use and its related complications is determined by multiple factors. We studied the effects of sudden ban of alcohol during elections in a state of India. We found that unexpected election bans could lead to severe complications in alcohol dependent individuals. Impact of sudden policy changes needs to be thought prior to implementation.
