Patients leaving hospital during Christmas at higher risk of death

Reduced staffing and lack of follow-up care could mean the December holiday period is a more vulnerable time for patients discharged from hospital, according to the BMJ

Patients sent home from hospital during the December holiday period are less likely to have a follow-up appointment, meaning they have a higher risk of death and readmission within 30 days. This is according to a study undertaken in Ontario, Canada in the Christmas issue of The BMJ.

Historically, there has been a lack of research on the December holiday period, so researchers at ICES in Canada set out to investigate whether patients discharged from hospital during this time are worse off than other times.

They analysed 217,305 cases of adults and children discharged from hospitals in Ontario during the two-week December holiday period, between 2002 and 2016.

This was compared with 453,641 cases of patients discharged during two control periods in late November and January.

The researchers excluded groups likely to have different follow-up needs and risk of re-admission, including newborns, pregnant women, patients admitted for palliative care and those with a long term hospital stay.

Those discharged during the Christmas holiday period were found to have a higher risk of death or readmission within the next seven, 14 and 30 days, with the greatest risk being at 16% within the first seven days.

In addition, those discharged during the holiday were also 39% less likely to have a follow-up appointment within seven days, possibly due to wanting to postpone until after the festivities, the researchers suggest.

Interestingly, patients with a higher baseline risk, such as those with lung disease, had a lower holiday-related risk of readmission and death than those with a lower baseline risk. The authors suggest that this could be because “in a setting of reduced resources over the holiday, clinicians [may] prioritise higher risk patients”.

The report also found that, per 100,000 patients, 26 more deaths,188 excess re-hospitalisations, 483 extra visits to an emergency department and 2,999 fewer follow-ups were associated with being discharged during the Christmas holiday.

The authors suggest that the Christmas festivities often involve excessive drinking and eating, heightened emotional stress and lack of sleep. “These altered circumstances could destabilise an acute medical condition”, they add.

The authors also highlight the limitations of the study and that they cannot rule out the possibility that some of the risk may be a result of other unmeasured factors. They say that “more detailed information on patient severity of illness would strengthen the argument for causation between discharge during the holiday period and health outcomes”.

They also acknowledge that their Ontario-based study may not be applicable to all populations – in particular, they note that “follow-up rates can be expected to vary according to local community practices”.

However, the study stresses the need for doctors to pay attention to discharge planning and coordination of care during the festive period.
