Regional Market Competition and the Use of Immediate Breast Reconstruction After Mastectomy.

ABSTRACT:

Background

Prior work has shown that the competitiveness of the market in which hospitals operate is associated with use of surgical procedures. This study examined the association between regional market competition and use of breast reconstruction for women with breast cancer and ductal carcinoma in situ undergoing mastectomy.

Methods

Women who underwent mastectomy from 2010 to 2011 recorded in the National Inpatient Sample were selected. The competitive market environment for each hospital in which patients were treated was estimated using the Herfindahl-Hirschman Index. Multivariable models were developed to examine the association between regional market competition and breast reconstruction, with adjustment for other clinical, demographic, and structural variables.

Results

Immediate breast reconstruction was performed for 9902 (45%) of 22,011 women. The rate of immediate breast reconstruction was 34.5% at hospitals in non-competitive markets, 49% at hospitals in moderately competitive markets, and 56.4% at hospitals in highly competitive markets (P < 0.0001). In a multivariable model, women in moderately competitive markets were 24% (risk ratio [RR] 1.24; 95% confidence interval [CI] 1.10-1.41) more likely to undergo immediate breast reconstruction than women in noncompetitive markets, whereas those in competitive markets were 25% (RR 1.25; 95% CI 1.11-1.41) more likely to have reconstruction. Later year of treatment, higher census tract income level, and residence in an urban area were associated with an increased likelihood of reconstruction (P < 0.05 for all). In contrast, older age, non-white race, and non-commercial insurance were associated with a lower likelihood of reconstruction (P < 0.05 for all).

Conclusion

Patients who undergo mastectomy at hospitals in competitive markets are more likely to undergo immediate breast reconstruction.

Project description:Purpose The goals of immediate postmastectomy breast reconstruction are to minimize deformity and optimize quality of life as perceived by patients. We prospectively evaluated patient-reported outcomes (PROs) in women undergoing immediate implant-based or autologous reconstruction. Methods Women undergoing immediate postmastectomy reconstruction for invasive cancer and/or carcinoma in situ were enrolled at 11 sites. Women underwent implant-based or autologous tissue reconstruction. Patients completed the BREAST-Q, a condition-specific PRO measure for breast surgery patients, and Patient-Reported Outcomes Measurement Information System-29, a generic PRO measure, before and 1 year after surgery. Mean changes in PRO scores were summarized. Mixed-effects regression models were used to compare PRO scores across procedure types. Results In total, 1,632 patients (n = 1,139 implant, n = 493 autologous) were included; 1,183 (72.5%) responded to 1-year questionnaires. After analysis was controlled for baseline values, patients who underwent autologous reconstruction had greater satisfaction with their breasts than those who underwent implant-based reconstruction (difference, 6.3; P < .001), greater sexual well-being (difference, 4.5; P = .003), and greater psychosocial well-being (difference, 3.7; P = .02) at 1 year. Patients in the autologous reconstruction group had improved satisfaction with breasts (difference, 8.0; P = .002) and psychosocial well-being (difference, 4.6; P = .047) compared with preoperative baseline. Physical well-being of the chest was not fully restored in either the implant group (difference, -3.8; P = .001) or autologous group (-2.2; P = .04), nor was physical well-being of the abdomen in patients who underwent autologous reconstruction (-13.4; P < .001). Anxiety and depression were mitigated at 1 year in both groups. Compared with their baseline reports, patients who underwent implant reconstruction had decreased fatigue (difference, -1.4; P = .035), whereas patients who underwent autologous reconstruction had increased pain interference (difference, 2.0; P = .006). Conclusion At 1 year after mastectomy, patients who underwent autologous reconstruction were more satisfied with their breasts and had greater psychosocial and sexual well-being than those who underwent implant reconstruction. Although satisfaction with breasts was equal to or greater than baseline levels, physical well-being was not fully restored. This information can help patients better understand expected outcomes and may guide innovations to improve outcomes.

Project description:BackgroundAfter breast cancer, some patients report residual pain-related upper limb disability without physical impairment. Although pain and altered proprioception are known to affect the working body schema (WBS), there is little available evidence investigating the WBS of breast cancer survivors (BrCS). WBS-body representations in the brain-affect the "neuromatrix" that modulates pain sensitivity and the threshold for threatening stimuli. The aim of this study was to investigate whether WBS was disrupted after mastectomy with immediate breast reconstruction (IBR) for breast cancer and whether pain and proprioceptive changes affected WBS.MethodsThirty-five BrCS participated in the 4-month follow-up study. They were observed at 1 and 4 months postoperatively. The main outcome measures were the left right judgement test (LRJT) results, absolute angle error, pectoralis minor length index (PMI), pain, and Quick-Disabilities of the Arm, Shoulder, and Hand (Q-DASH) score. They were measured at each observation, and parametric tests were performed to identify the nature of WBS.ResultsBoth the reaction time and accuracy of the hand LRJT were poorer than those of the foot and back LRJT (p < 0.001). The hand LRJT reaction time and accuracy were unchanged over the total follow-up period (p = 0.77 and p = 0.47, respectively). There was a weak correlation between the LRJT reaction time and PMI (r = -0.26, p = 0.07), pain severity (r = 0.37, p = 0.02), and Q-DASH score (r = 0.37, p = 0.02). There was also a weak correlation between LRJT accuracy and Q-DASH score (r = -0.31, p = 0.04). The LRJT accuracy of BrCS who underwent surgery on their dominant side was higher than that of BrCS who underwent surgery on their non-dominant side (p = 0.002). Regression analysis found a weak but significant relationship between the early hand LRJT results and late pain severity (adjusted R2 = 0.179, p = 0.007). A similar relationship was found between early hand LRJT results and Q-DASH score (adjusted R2 = 0.099, p = 0.039).ConclusionTo the best of our knowledge, this is the first study providing the nature of WBS after mastectomy with IBR. In this population, it is necessary to postoperatively preserve WBS integrity for pain and upper limb disability.
