Background. The ­aim of ­this ­study ­was to inves­ti­gate week­ly ­and sea­so­nal vari­a­tion of hos­pi­tal admis­sions, ­major ampu­ta­tions ­and mor­tal­ity in ­patients treat­ed ­for ­acute ­leg ischae­mia by sur­gi­cal ­and endo­vas­cu­lar pro­ce­dures.
Methods. Experimental ­design: Retrospective ­study. Setting: University (5), cen­tral (16) ­and dis­trict (4) hos­pi­tals par­tic­i­pat­ing in ­the Finnish nation­al vas­cu­lar reg­is­try Finnvasc. Patients: 1550 ­patients treat­ed ­for ­acute ­leg ischae­mia on ­the ­basis of ­the reg­is­try. Interventions: Surgical or endo­vas­cu­lar revas­cu­lar­isa­tion. Measures: Day of ­the ­week of hos­pi­tal admis­sion, ­major ampu­ta­tion ­and ­death.
Results. The week­ly pat­tern of ­the hos­pi­tal admis­sions ­was sig­nif­i­cant­ly non­-uni­form ­with a Monday ­peak ­and a week­end ­nadir. A ten­den­cy ­towards ­more hos­pi­tal admis­sions in ­the win­ter sea­son ­was ­found. Patients hos­pit­al­ised on Thursday or Friday tend­ed to ­have a low­er ampu­ta­tion ­rate com­pared to ­those hos­pit­al­ised in ­any oth­er ­day of ­week. The high­est ampu­ta­tion ­and mor­tal­ity ­rates ­were ­observed in ­the sum­mer sea­son.
Conclusions. Patients ­with ­acute ­leg ischae­mia ­seek med­i­cal ­help in a ­non-uni­form week­ly ­and sea­son­al pat­tern ­with var­y­ing out­comes.
