A Comparative Study of Attitudes Regarding Digit Replantation in the United States and Japan.

ABSTRACT: To compare the societal preferences for finger replantation between the United States (US) and Japan and to investigate factors influencing the preferences.A sample of the general population without current hand disease or condition was recruited via flyers posted in public areas of 2 major academic centers in the US and Japan. The recruited subjects completed a survey presenting finger amputation scenarios and various factors that may affect treatment decisions. We performed univariate analysis using treatment preference as the outcome and all other factors as possible predictors using the chi-square test.Most respondents in both countries preferred replantation and there was no significant difference between the US and Japan. Treatment preference was significantly associated with the importance of appearance, recovery time, and the chance of survival of the replanted digit. There was no association between treatment preference and attitudes regarding body integrity or estimate of stigma toward finger amputees. Japanese participants agreed more with statements of body integrity, and Japanese respondents rated appearance, sensation, and chance of survival of the replant as more important than did American participants.Patient preference is not driving the decrease in finger replantations in the US. The general public in both countries prefer replantation over wound closure for digit amputations.Economic and decision analysis III.

Project description:ImportanceRecent evidence suggests that select delayed replantation may not adversely affect digit survival; however, whether surgical timing (overnight or daytime) is associated with digit replantation outcomes is unknown.ObjectiveTo assess whether digit survival, complication rate, and duration of surgery are associated with time of replantation.Design, setting, and participantsThis retrospective case series study included all replantations performed at a single tertiary referral academic center between January 1, 2000, and August 1, 2021. Data were analyzed between October 2, 2021, and January 1, 2022. Four daytime surgery intervals were selected based on literature review. Daytime replantations started within the intervals whereas overnight replantations began outside the intervals. For each case, the procedure difficulty score and the attending surgeon expertise score were calculated. Logistic and linear regressions adjusting for confounders including procedure difficulty score and expertise score were used to assess surgical timing and outcomes. Participants were adults (aged ≥18 years) undergoing digit replantations between January 2000 and August 2021 with at least 1-month follow-up. Replantation was defined as the reattachment of a completely amputated digit that necessitated anastomosis of both artery and vein.ExposuresDaytime or overnight digit replantation.Main outcomes and measuresViable replanted digit at 1-month follow-up, number of complications, and duration of surgery.ResultsA total of 98 patients (mean [SD] age, 39.5 [15.3] years; 136 [93%] men) and 147 digits met inclusion criteria. Overall success rate was 55%. Between 4 pm and 7 am, overnight replantations were associated with 0.4 fewer complications (β, -0.4; 95% CI, -0.8 to -0.1) and 90.7 minutes shorter operative time (β, -90.7; 95% CI, -173.6 to -7.7). A 1-point increase in surgeon expertise score was associated with 1.7 times increased odds of replantation success for all intervals (adjusted odds ratio, 1.7; 95% CI, 1.2 to 2.4; P = .002). There were no differences in digit survival by surgical time.Conclusions and relevanceIn this case series study of digit replantations, time of operation was not associated with replantation success. Overnight replantation was associated with fewer complications and shorter duration of surgery compared with daytime surgery. Results of this study suggest that overnight replantations may be performed with outcomes comparable to daytime replantations at a tertiary care academic center.

Project description:ImportanceRisk-adjusted variation in surgeon outcomes has been traditionally explained by surgeon volume and hospital infrastructure, yet it is unclear how a surgeon's operative proficiency directly contributes to their patients' outcomes.ObjectiveTo assess the variation of surgeons' operative proficiency and investigate its association with surgical outcomes.Design, setting, and participantsThis case series was a retrospective analysis of all digit replantations and revascularizations at a single US university medical center between January 2000 and August 2020. Surgeons were assigned a proficiency score based on the expected procedure difficulty and outcomes from a sample of their cases. Surgeon proficiency scores were then used to determine associations with outcomes from subsequent cases. The expected difficulty of each case was calculated using a novel scoring system that applied pooled relative risks from a meta-analysis of risk factors for replantation and revascularization failure.ExposuresDigit replantation and revascularization.Main outcomes and measuresDigit survival at 1-month follow up (case success) and number of complications.ResultsA total of 145 patients and 226 digits were treated by 11 surgeons with training in hand or microsurgery (mean [SD] age, 41.9 [15.2] years; 204 [90%] men); there were 116 replantations and 110 revascularizations. Surgeon proficiency scores ranged from 1.3 to 5.7, with a mean (SD) of 3.4 (1.4). Case success rates among surgeons varied from 20.0% to 90.5%, with a mean (SD) of 64.9%. Higher proficiency scores were associated with fewer case failures: each point increase was associated with 40% decreased odds of failure (odds ratio, 0.60; 95% CI, 0.38-0.94). Every 3-point increase in proficiency score was associated with 1 less complication (effect estimate, -0.29; 95% CI, -0.56 to 0.02). Surgeon proficiency score had a greater association with case failure than surgeon volume (16.7% vs 12.0%). The final model's association with case failure had an area under the receiver operating characteristics curve of 0.93.Conclusions and relevanceOperative proficiency varied widely among practicing surgeons and accounted for 17% of estimative ability for success of digit replantation and revascularization. Greater surgeon proficiency was associated with better outcomes, indicating that the value of surgical care may be optimized by improving surgeon proficiency.
