“…We found a significant correlation in our study between BMI and the operative time (p = 0.017), which is in keeping with the literature that has shown that high BMI leads to longer operative time during primary THA [19,20]. Bradley et al [21] have shown that each point increase in BMI resulted in an increased operative time of 1.46 min during primary THA. In our study, we observed a trend toward higher BMIs in Group 2 (mean = 27) when compared to Group 1 (mean = 26).…”

“…Data released in 2012 revealed that 26.2% of the UK adult population are obese (i.e. body mass index (BMI) >30 kg/m 2 ) compared to 13.2% in 1993 [3]. NJR supports this observation, demonstrating that the number of elective primary TKR procedures performed in obese patients (BMI >30 kg/m 2 ) is increasing.…”

“…Twenty Six % of patients undergoing primary hip arthroplasty in 2011 were obese compared with 21% in 2004. Thirty two % of patients that received a TKR in 2011 were obese compared with 28% in 2004 [3]. Based on changing population demographics of age, sex, BMI; in the year 2035, about 1,219,362 TKRs will be carried out [4].…”

“…Male gender also predicted a higher complication rate [24] . Obesity resulted in a longer hospital LOS [17,27,28] , readmission rate [19,20,23,27] , and complication rate [21,22,28] . An underweight status has also been shown to increase the rate of readmission [20] .…”

AIM:To determine the impact of different characteristics on postoperative outcomes for patients in a joint arthroplasty Perioperative Surgical Home (PSH) program. METHODS:A retrospective review was performed for patients enrolled in a joint arthroplasty PSH program who had undergone primary total hip arthroplasty (THA) and total knee arthroplasty (TKA). Patients were preoperatively stratified based on specific procedure performed, age, gender, body mass index (BMI), American Society of Anesthesiologists Physical Classification System (ASA) score, and Charleston Comorbidity Index (CCI) score. The primary outcome criterion was hospital length of stay (LOS). Secondary criteria including operative room (OR) duration, trans- RESULTS:A total of 337 patients, 200 in the TKA cohort and 137 in the THA cohort, were eligible for the study. Nearly two-third of patients were female. Patient age averaged 64 years and preoperative BMI averaged 29 kg/m 2 . The majority of patients were ASA score Ⅲ and CCI score 0. After analysis, ASA score was the only variable predictive for LOS (P = 0.0011) and each increase in ASA score above 2 increased LOS by approximately 0.5 d. ASA score was also the only variable predictive for readmission rate (P = 0.0332). BMI was the only variable predictive for PACU duration (P = 0.0136). Specific procedure performed, age, gender, and CCI score were not predictive for any of the outcome criteria. OR duration, transfusion rate, postoperative complications or discharge disposition were not significantly associated with any of the predictor variables. CONCLUSION:The joint arthroplasty PSH model reduces postoperative outcome variability for patients with different preoperative characteristics and medical comorbidities.
