Is the weekend effect true in acute stroke patients at tertiary stroke center?

Weekend / holiday effect on stroke mortality in regional Australia: A ten-year retrospective study

BACKGROUND

There is a deficiency in the evidence from rural and regional centres in Australia on the weekend effect following presentation with acute stroke.

OBJECTIVE

To estimate the association between admission over a weekend/holiday and all-cause mortality 3-day, 7-day, 14-day, 1-month, 3-month, 6-month, and 12-month following acute stroke.

METHODS

The records of stroke patients admitted to a main regional hospital in Australia from 2010 to 2020 were linked with the National Death Index. Time to death following ischaemic, haemorrhagic, and total stroke at different time points was modelled using Weibull, Exponential, or Gompertz regression based on best model fit determined by Akaike's information criterion.

RESULTS

Of 1669 patients, 1273 (76.3%) were admitted on a weekday, and 396 (23.7%) on a weekend/ or holiday. After adjusting for age, sex, and Charlson Comorbidity Index, stroke type and country of birth, admissions over a weekend/holiday following total stroke were significantly associated with an increased risk of dying within three days from admission [hazard ratio (HR): 1.59, 95% confidence interval: 1.01-2.50]. In haemorrhagic stroke, increased risk of death was significantly higher at three days (HR: 2.19, 95% confidence interval: 1.17-4.08), 14 days (HR: 1.73, 95% confidence interval: 1.02-2.93), and 1 month (HR: 1.82, 95% confidence interval: 1.09-3.03) following admission on the weekend/ or holiday compared to those admitted during the weekdays.

CONCLUSIONS

This study reports a short-term adverse weekend/holiday effect following admission for haemorrhagic stroke or total stroke. No significant weekend/holiday effect was found in ischaemic stroke.

The Management and Outcome of Stroke Patients Admitted on Weekdays Compared to Weekends at the King Abdulaziz Medical City, Riyadh, Saudi Arabia

Background and Purpose

Stroke is an unexpected medical emergency that can result in significant disability. The weekend effect suggests that individuals with acute medical problems are not treated the same way on weekends as they are on weekdays. There is no previous published study about weekend effect on stroke patients from Saudi Arabia.

Methods

This was an IRB approved, retrospective, cohort study. All stroke patients admitted between January 2017 and December 2018 were included. Ten standards of care were chosen to assess compliance with standardized care. Seven measures were chosen for acute management of stroke.

Results

A total of 731 patients were included, 68.5% were males; 493 (67%) were admitted during weekdays and 238 (33%) on weekends. There was no difference for age (P = .32), gender (P = .32), nationality (P = .62), stroke subtype (P = .27) and stroke severity (P = .69) on weekday or weekend admission. In two-third patients, more than 70% of stroke orders were utilized, with no difference in thrombolysis rate (P = .81). There was no difference in recurrent stroke (P = .86), mortality or discharge disposition (P = .34) between the patients. The patients admitted during weekdays had less complications (38 vs 46%; P = .04).

Conclusions

There was no difference in the quality of care provided to stroke patients admitted during weekdays or weekends. There was no difference in the use of acute intervention on weekends and weekdays. Patients had similar outcomes and discharge disposition whether admitted on weekdays or weekends, except that those admitted on weekends had a significantly greater overall number of complications.
