In this issue of JAMA Ophthalmology, Vail and coauthors1 evaluated whether there is an association between the type of repair for rhegmatogenous retinal detachment (RRD) and the day of the week that patients receive their diagnosis or treatment.1 Using a large commercial claims and encounters database, IBM MarketScan, they found that pneumatic retinopexy (PR) was more likely to be performed if the patient received a diagnosis or underwent surgery performed on Friday to Sunday compared with the other days of the week. Such an association was not observed for other forms of RRD repair. They conclude that PR was “disproportionately likely to be used” during the weekend. Additionally, they describe that patients undergoing PR on Sundays were more prone to require reoperation within 30 days compared with when PR was performed on other days of the week. Poorer outcomes for patients requiring emergent medical treatment on a weekend, the so-called weekend effect, was first demonstrated in 2001 by Bell and Redelmeier2 and has been much debated but to our knowledge, not previously described for patients with RRD.
