15 In a single study comparing treatment options according to the ASA scores
of patients, Ifversen and Kjaer6 found a lower mortality rate and a longer survival duration in the electively treated group than that of the observed group, even if the median ASA score
was lower in the elective surgery group (ASA II vs.
Table 2 summarizes the 16 clinical cases of PSI concerning demographics, ASA score
, diagnosis prior to arthroplasty, type of surgery, presence of hematoma, time elapsed between surgery and PSI, microorganism identified, and the selected medical treatment.
There were no statistically significant differences between the two groups for BMI, ASA score
, tumour side and localization, type of surgery (LPN vs.
For each patient, the National Nosocomial Infection Surveillance (NNIS) system risk index was computed on the basis of an ASA score
higher than two, a wound class of contaminated or dirty/infected, and the duration of procedure > 81 minutes, with each criterion met adding one point to the index.
Details of the surgery and patient profile along with various risk factors were collected in predesigned proforma which include age, diabetes, preoperative hospital stay, ASA score
, nature and type of surgery, type of anaesthesia, duration of surgery, and surgical technique.
Demographic and other characteristics including VAS value, ASA score
, comorbidities, the length of hospital stay; of the patients in two groups are presented in Table 1.
Age, sex, race, and ASA score
were compared between the two time periods.

of 2 and history of bilateral arthroplasty in 2006 and 2009, who consulted in 2012 for left hip pain associated with systemic inflammatory reaction (Table 1).
Conclusions: We propose that age, ASA score
and albumin level pre-PEG insertion to be included as factors to assist in the selection of patients who are likely to survive more than 3 months post PEG insertion.
Subgroup analysis was performed on patients who had an ASA score
of 1 or 2, versus those with an ASA of 3 or 4.
