Aim of our study is to evaluate the frequency and features of admissions performed at an Infectious Diseases Day-Hospital service at S. Orsola Hospital, Bologna, Italy.
A retrospective evaluation of all admissions of the last 15 years (1994-2008), was performed.
Before the introduction of potent, combination antiretroviral treatments (cART) (years 1994-1996), the proportionally low mean number of admissions (110/year), was linked to the elevated prevalence of HIV disease, which accounted for 89.4% of Day-Hospital hospitalizations, their recurrence, and their prolonged duration. Immediately after cART introduction, the number of Day-Hospital admissions showed a significant increase, from 171 (year 1997), to 318 (2002),338 (2003),347 (2004),331 (2005),356 (2006), 341 (2007), and 378 (2008) (p < .0001 versus the pre-cART era), although this phenomenon paralleled a drop of percentage of HIV-related admissions (from 59.1% of 1997, to a minimum of 23.8% of the year 2005; p < .0001). While HIV-associated hospitalizations decreased, a temporal increase of admissions due to chronic liver disease occurred (p < .0001). The reduction of admission duration allowed an increase of overall number of hospitalizations of each examined year (p < .0001), and the mean bed occupation rate showed a continued rise (8.2 in the year 2000, to maximum value of 12.0 reached in the year 2006 (p < .0001).
The modifications occurred at our Infectious Diseases Day-Hospital service during the last 15 years are largely attributable to the significant changes occurred in the spectrum of infectious disorders which came to our attention: from a low number of prolonged hospitalizations typical of patients with advanced HIV disease, the cART era led to a progressive broadening of the spectrum of disease, and a notable reduction of admission time. Notwithstanding this situation, no significant modification was observed as to mean weight of diagnosis-related group (DRG) features:from a mean 1.03 rate per patient of the year 2000, to a mean 1.33 figure in the year 2008. The evolution of assistance features in a Day-Hospital setting, seems strictly linked to the modification of prevailing disorders. A permanent monitoring of the features of health care provision at an Infectious Disease Day-Hospital service may allow to consider significant temporal modifications, and contribute to ensure adequate assistential planning, including the eventual revision of structural, professional, technical, and funding resources.
