RESUMO
BACKGROUND: Tobacco use is a well-documented modifiable risk factor for perioperative complications. AIM: To determine the tobacco abstinence rates of patients who made cessation efforts prior to a total joint arthroplasty (TJA) procedure. METHODS: A retrospective evaluation was performed on 88 self-reported tobacco users who underwent TJA between 2014-2022 and had tobacco cessation dates within 3 mo of surgery. Eligible patients were contacted via phone survey to understand their tobacco use pattern, and patient reported outcomes. A total of 37 TJA patients participated. RESULTS: Our cohort was on average 61-years-old, 60% (n = 22) women, with an average body mass index of 30 kg/m2. The average follow-up time was 2.9 ± 1.9 years. A total of 73.0% (n = 27) of patients endorsed complete abstinence from tobacco use prior to surgery. Various cessation methods were used perioperatively including prescription therapy (13.5%), over the counter nicotine replacement (18.9%), cessation programs (5.4%). At final follow up, 43.2% (n = 16) of prior tobacco smokers reported complete abstinence. Patients who were able to maintain cessation postoperatively had improved Patient-Reported Outcomes Measurement Information System (PROMIS)-10 mental health scores (49 vs 58; P = 0.01), and hip dysfunction and osteoarthritis outcome score for joint replacement (HOOS. JR) scores (63 vs 82; P = 0.02). No patients in this cohort had a prosthetic joint infection or required revision surgery. CONCLUSION: We report a tobacco cessation rate of 43.2% in patients undergoing elective TJA nearly 3 years postoperatively. Patients undergoing TJA who were able to remain abstinent had improved PROMIS-10 mental health scores and HOOS. JR scores. The perioperative period provides clinicians a unique opportunity to assist active tobacco smokers with cessation efforts and improve postoperative outcomes.
RESUMO
BACKGROUND: With the increasing incidence of total joint arthroplasty (TJA), there is a desire to reduce peri-operative complications and resource utilization. As degenerative conditions progress in multiple joints, many patients undergo multiple procedures. AIM: To determine if both physicians and patients learn from the patient's initial arthroplasty, resulting in improved outcomes following the second procedure. METHODS: The institutional database was retrospectively queried for primary total hip arthroplasty (THA) and total knee arthroplasty (TKA). Patients with only unilateral THA or TKA, and patients undergoing same-day bilateral TJA, were excluded. Patient demographics, comorbidities, and implant sizes were collected at the time of each procedure and patients were stratified by first vs second surgery. Outcome metrics evaluated included operative time, length of stay (LOS), disposition, 90-d readmissions and emergency department (ED) visits. RESULTS: A total of 642 patients, including 364 undergoing staged bilateral TKA and 278 undergoing bilateral THA, were analyzed. There was no significant difference in demographics or comorbidities between the first and second procedure, which were separated by a mean of 285 d. For THA and TKA, LOS was significantly less for the second surgery, with 66% of patients having a shorter hospitalization (P < 0.001). THA patients had significantly decreased operative time only when the same sized implant was utilized (P = 0.025). The vast majority (93.3%) of patients were discharged to the same type of location following their second surgery. However, when a change in disposition was present from the first surgery, patients were significantly more likely to be discharged to home after the second procedure (P = 0.033). There was no difference between procedures for post-operative readmissions (P = 0.438) or ED visits (P = 0.915). CONCLUSION: After gaining valuable experience recovering from the initial surgery, a patient's perioperative outcomes are improved for their second TJA. This may be the result of increased confidence and decreased anxiety, and it supports the theory that enhanced patient education pre-operatively may improve outcomes. For the surgical team, the second procedure of a staged THA is more efficient, although this finding did not hold for TKA.
RESUMO
Computer-navigated total knee arthroplasty (CN-TKA) has been used to improve component alignment, though the evidence is currently mixed on whether there are clinically significant differences in long-term outcomes. Given the established increased costs and operative time, we hypothesized that the utilization rate of CN-TKA would be decreasing relative to standard TKA in the Medicare population given the current health care economic environment. We queried 1,914,514 primary TKAs performed in the entire Medicare database from 2005 to 2012. Current Procedural Terminology (CPT) and International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes were used to identify and separate CN-TKAs. Utilization of TKA was compared by year, gender, and region. Average change in cases per year and compound annual growth rate (CAGR) were used to evaluate trends in utilization of the procedure. We identified 30,773 CN-TKAs performed over this time period. There was an increase in utilization of CN-TKA per year from 984 to 5,352 (average = 572/year, R (2) = 0.85, CAGR = 23.58%) from 2005 to 2012. In contrast, there was a slight decrease in overall TKA utilization from 264,345 to 230,654 (average = 4297/year, R (2) = 0.74, CAGR = - 1.69%). When comparing proportion of CN-TKA to all TKAs, there was an increase from 0.37 to 2.32% (average 0.26%/year, R (2) = 0.88, CAGR = 25.70%). CN-TKA growth in males and females was comparable at 24.42 and 23.11%, respectively. The South region had the highest growth rate at 28.76%, whereas the Midwest had the lowest growth rate at 15.51%. The Midwest was the only region that peaked (2008) with a slow decline in utilization until 2012. Despite increased costs with unclear clinical benefit, CN-TKA is increasing in utilization among Medicare patients. Reasons could include patient preference, advertising, proper of coding the procedure, and increased publicly available information about arthroplasty options.
