Long-term followup for rheumatoid arthritis patients in a multicenter outcomes study of silicone metacarpophalangeal joint arthroplasty.

ABSTRACT: Rheumatoid arthritis (RA) often results in deformities at the metacarpophalangeal (MCP) joints. Patients with severe deformities can be treated by silicone metacarpophalangeal joint arthroplasty (SMPA). The objective of the study is to prospectively compare long-term outcomes for an SMPA surgical and a nonsurgical cohort of RA patients.A total of 67 surgical and 95 nonsurgical patients with severe subluxation and/or ulnar drift of the fingers at the MCP joints were recruited from 2004-2008 in this multicenter prospective cohort study. Patients could elect to undergo SMPA or not. Outcomes included the Michigan Hand Outcomes Questionnaire (MHQ), Arthritis Impact Measurement Scales 2 (AIMS2), grip/pinch strength, Jebsen-Taylor Test, ulnar deviation, extensor lag, and arc of motion measurements at the MCP joints.There was no significant difference in the mean age, race, education, and income at baseline between the 2 groups. Surgical subjects had worse MHQ function and functional measurements at baseline. At 3 years, the mean overall MHQ score and the MHQ function, activities of daily living, aesthetics, and satisfaction scores showed significant improvement in the surgical group compared to the nonsurgical group. Ulnar deviation, extensor lag, and arc of motion in the MCP and proximal interphalangeal joints also improved significantly in the surgical group. No improvement was seen in the mean AIMS2 scores and grip/pinch strength. Complications were minimal with a fracture rate of 9.5%.RA patients with poor baseline functioning showed long-term improvement in hand function and appearance following treatment with SMPA compared to nonsurgical controls.

Project description:BackgroundThere is a paucity of research evaluating the cost-effectiveness of surgical interventions for rheumatoid arthritis patients. Previous reports have challenged the sustainability of improved outcomes after silicone metacarpophalangeal arthroplasty. The authors conducted an economic evaluation of the long-term health outcomes after silicone metacarpophalangeal arthroplasty.MethodsThe authors performed a 5-year prospective cohort study of 170 patients with rheumatoid arthritis (73 surgical and 97 nonsurgical). Objective functional measurements and patient-rated outcomes using the Michigan Hand Outcomes Questionnaire and the Arthritis Impact Measurement Scale 2 were collected at 3 and 5 years. A cost-effectiveness analysis using direct costs from Medicare outpatient claims data (2006 to 2010) was performed to estimate the incremental cost-effectiveness ratios for both the Michigan and Arthritis Impact Measurement Scale 2 measurements.ResultsAt 5 years, the authors observed a statistically significant difference in upper extremity outcomes (Michigan Hand Outcomes Questionnaire) between the two groups, with surgical patients having higher outcomes. Costs associated with improved outcomes 5 years after surgery were $787 to $1150 when measured by the Michigan Hand Outcomes Questionnaire and $49,843 to $149,530 when measured by the Arthritis Impact scale. The incremental cost-effectiveness ratios did not substantially increase with their observed surgical revision rate of 5.5 percent (approximately 4 percent increase in incremental cost-effectiveness ratio) or with previously published long-term revision rates of 6.2 percent (approximately 6 percent increase in incremental cost-effectiveness ratio).ConclusionsShort-term improvements in upper extremity outcomes after silicone metacarpophalangeal arthroplasty are maintained over the 5-year follow-up period. These outcomes are achieved at a relatively low cost, even with the addition of potential surgical complications.

Project description:ImportanceIndividuals with total joint arthroplasty (TJA) have long-term exposure to metal-containing implants; however, whether long-term exposure to artificial implants is associated with cognitive function is unknown.ObjectiveTo compare long-term cognitive trajectories in individuals with and without TJA.Design, setting, and participantsThis population-based cohort study assessed serial cognitive evaluations of 5550 participants (≥50 years of age) from the Mayo Clinic Study of Aging between November 1, 2004, and December 31, 2020.ExposuresTotal joint arthroplasty of the hip or the knee.Main outcomes and measuresLinear mixed-effects models were used to compare the annualized rate of change in global and domain-specific cognitive scores in participants with and without TJA, adjusting for age, sex, educational level, apolipoprotein E ε4 carrier status, and cognitive test practice effects.ResultsA total of 5550 participants (mean [SD] age at baseline, 73.04 [10.02] years; 2830 [51.0%] male) were evaluated. A total of 952 participants had undergone at least 1 TJA of the hip (THA, n = 430) or the knee (TKA, n = 626) before or after entry into the cohort. Participants with TJA were older, more likely to be female, and had a higher body mass index than participants without TJA. No difference was observed in the rate of cognitive decline in participants with and without TJA until 80 years of age. A slightly faster cognitive decline at 80 years or older and more than 8 years from surgery was observed (b = -0.03; 95% CI, -0.04 to -0.02). In stratified analyses by surgery type, the faster decline was observed primarily among older participants with TKA (b = -0.04; 95% CI, -0.06 to -0.02).Conclusions and relevanceIn this cohort study, long-term cognitive trajectories in individuals with and without TJA were largely similar except for a slightly faster decline among the oldest patients with TKA; however, the magnitude of difference was small and of unknown clinical significance.

Project description:BackgroundA web-based followup assessment may be a feasible, cost-saving alternative of tracking patient outcomes after total joint arthroplasty. However, before implementing a web-based program, it is important to determine patient satisfaction levels with the new followup method. Satisfaction with the care received is becoming an increasingly important metric, and we do not know to what degree patients are satisfied with an approach to followup that does not involve an in-person visit with their surgeons.Questions/purposesWe determined (1) patient satisfaction and (2) patients' preferences for followup method (web-based or in-person) after total joint arthroplasty.MethodsWe randomized patients who were at least 12 months after primary THA or TKA to complete a web-based followup or to have their appointment at the clinic. There were 410 eligible patients contacted for the study during the recruitment period. Of these, 256 agreed to participate, and a total of 229 patients completed the study (89% of those enrolled, 56% of those potentially eligible; 111 in the usual-care group, 118 in the web-based group). Their mean age was 69 years (range, 38-86 years). There was no crossover between groups. All 229 patients completed a satisfaction questionnaire at the time of their followup appointments. Patients in the web-based group also completed a satisfaction and preference questionnaire 1 year later. Only patients from the web-based group were asked to indicate preference as they had experienced the web-based and in-person followup methods. We used descriptive statistics to summarize the satisfaction questionnaires and compared results using Pearson's chi-square test.ResultsNinety-one patients (82.0%) in the usual-care group indicated that they were either extremely or very satisfied with the followup process compared with 90 patients (75.6%) who were in the web-based group (p < 0.01; odds ratio [OR] = 3.95; 95% CI, 1.79-8.76). Similarly, patients in the usual care group were more satisfied with the care they received from their surgeon, compared with patients in the web-based group (92.8% versus 73.9%; p < 0.01, OR = 1.37; 95% CI, 0.73-2.57). Forty-four percent of patients preferred the web-based method, 36% preferred the usual method, and 16% had no preference (p = 0.01).ConclusionsOur results show moderate to high satisfaction levels with a web-based followup assessment. Patients who completed the usual method of in-person followup assessment reported greater satisfaction; however, the difference was small and may not outweigh the additional cost and time-saving benefits of the web-based followup method.Level of evidenceLevel I, therapeutic study.
