Antiretroviral Therapy Use and Disparities Among Medicare Beneficiaries with HIV.

BACKGROUND: Antiretroviral therapy (ART) is recommended for all people with HIV. Understanding ART use among Medicare beneficiaries with HIV is therefore critically important for improving quality and equity of care among the growing population of older adults with HIV. However, a comprehensive national evaluation of filled ART prescriptions among Medicare beneficiaries is lacking. OBJECTIVE: To examine trends in ART use among Medicare beneficiaries with HIV from 2013 to 2019 and to evaluate whether racial and ethnic disparities in ART use are narrowing over time. DESIGN: Retrospective observational study. SUBJECTS: Traditional Medicare beneficiaries with Part D living with HIV in 2013-2019. MAIN MEASURES: Months of filled ART prescriptions each year. KEY RESULTS: Compared with beneficiaries not on ART, beneficiaries on ART were younger, less likely to be Black (41.6% vs. 47.0%), and more likely to be Hispanic (13.1% vs. 9.7%). While the share of beneficiaries who filled ART prescriptions for 10 + months/year improved (+ 0.48 percentage points/year [p.p.y.], 95% CI 0.34-0.63, p < 0.001), 25.8% of beneficiaries did not fill ART for 10 + months in 2019. Between 2013 and 2019, the proportion of beneficiaries who filled ART for 10 + months improved for Black beneficiaries (65.8 to 70.3%, + 0.66 p.p.y., 95% CI 0.43-0.89, p < 0.001) and White beneficiaries (74.8 to 77.4%, + 0.38 p.p.y.; 95% CI 0.19-0.58, p < 0.001), while remaining stable for Hispanic beneficiaries (74.5 to 75.0%, + 0.12 p.p.y., 95% CI - 0.24-0.49, p = 0.51). Although Black-White disparities in ART use narrowed over time, the share of beneficiaries who filled ART prescriptions for 10 + months/year was significantly lower among Black beneficiaries relative to White beneficiaries each year. CONCLUSIONS: ART use improved from 2013 to 2019 among Medicare beneficiaries with HIV. However, about 25% of beneficiaries did not consistently fill ART prescriptions within a given year. Despite declining differences between Black and White beneficiaries, concerning disparities in ART use persist.

Closed-loop automated drug infusion regulator: A clinically translatable, closed-loop drug delivery system for personalized drug dosing.

BACKGROUND: Dosing of chemotherapies is often calculated according to the weight and/or height of the patient or equations derived from these, such as body surface area (BSA). Such calculations fail to capture intra- and interindividual pharmacokinetic variation, which can lead to order of magnitude variations in systemic chemotherapy levels and thus under- or overdosing of patients. METHODS: We designed and developed a closed-loop drug delivery system that can dynamically adjust its infusion rate to the patient to reach and maintain the drug's target concentration, regardless of a patient's pharmacokinetics (PK). FINDINGS: We demonstrate that closed-loop automated drug infusion regulator (CLAUDIA) can control the concentration of 5-fluorouracil (5-FU) in rabbits according to a range of concentration-time profiles (which could be useful in chronomodulated chemotherapy) and over a range of PK conditions that mimic the PK variability observed clinically. In one set of experiments, BSA-based dosing resulted in a concentration 7 times above the target range, while CLAUDIA keeps the concentration of 5-FU in or near the targeted range. Further, we demonstrate that CLAUDIA is cost effective compared to BSA-based dosing. CONCLUSIONS: We anticipate that CLAUDIA could be rapidly translated to the clinic to enable physicians to control the plasma concentration of chemotherapy in their patients.

Disparity Reduction in United States Breast Reconstruction: An Analysis From 2005-2017 Using 3 Nationwide Data Sets.

BACKGROUND: Following passage of the Women's Health and Cancer Rights Act (WHCRA), a steady rise in breast reconstruction rates was reported; however, a recent update is lacking. This study aimed to evaluate longitudinal trends in breast reconstruction (BR) rates in the U.S. and relevant sociodemographic factors. METHODS: Mastectomy cases with/without BR from 2005 through 2017 were abstracted from the National Surgical Quality Improvement Program (NSQIP), Surveillance, Epidemiology, and End Results (SEER) Program, and National Cancer Database (NCDB). BR rates were examined using Poisson regression. Multivariable logistic regression analysis of NCDB data was used to identify predictors of reconstruction. Race and insurance distributions were evaluated over time. RESULTS: Of 1,554,381 mastectomy patients, 507,631 (32.7%) received BR. Annual reconstruction rates per 1000 mastectomies increased from 2005 to 2012 (NSQIP: Incidence Rate Ratio (IRR) 1.077; SEER: 1.090; NCDB: 1.092) and stabilized from 2013 to 2017. NCDB data showed that patients who were younger (≤59 years), privately insured, had fewer comorbidities, and underwent contralateral prophylactic mastectomy were more likely to undergo BR (all p<0.001). Over time, the increase in BR rates was higher among Black (252.3%) and Asian (366.4%) patients than White patients (137.3%). BR rates increased more among Medicaid (418.6%) and Medicare (302.8%) patients than privately insured (125.3%) patients. CONCLUSIONS: This analysis demonstrates stabilization in immediate BR rates over the last decade; reasons behind this stabilization are likely multifactorial. Disparities based on race and insurance type have decreased, with a more equitable distribution of BR rates.

Remote Symptom Monitoring with Clinical Alerts Following Mastectomy: Do Early Symptoms Predict 30-Day Surgical Complications.

BACKGROUND: Electronic patient-reported outcome measures (ePROMs) for real-time remote symptom monitoring facilitate early recognition of postoperative complications. We sought to determine whether remote, electronic, patient-reported symptom-monitoring with Recovery Tracker predicts 30-day readmission or reoperation in outpatient mastectomy patients. METHODS: We conducted a retrospective review of breast cancer patients who underwent outpatient (< 24-h stay) mastectomy with or without reconstruction from April 2017 to January 2022 and who received the Recovery Tracker on Days 1-10 postoperatively. Of 5,130 patients, 3,888 met the inclusion criteria (2,880 mastectomy with immediate reconstruction and 1,008 mastectomy only). We focused on symptoms concerning for surgical complications and assessed if symptoms reaching prespecified alert levels-prompting a nursing call-predicted risk of 30-day readmission or reoperation. RESULTS: Daily Recovery Tracker response rates ranged from 45% to 70%. Overall, 1,461 of 3,888 patients (38%) triggered at least one alert. Most red (urgent) alerts were triggered by pain and fever; most yellow (less urgent) alerts were triggered by wound redness and pain severity. The 30-day readmission and reoperation rates were low at 3.8% and 2.4%, respectively. There was no statistically significant association between symptom alerts and 30-day reoperation or readmission, and a clinically relevant increase in risk can be excluded (odds ratio 1.08; 95% confidence interval 0.8-1.46; p = 0.6). CONCLUSIONS: Breast cancer patients undergoing mastectomy with or without reconstruction in the ambulatory setting have a low burden of concerning symptoms, even in the first few days after surgery. Patients can be reassured that symptoms that do present resolve quickly thereafter.

Early Complications in Prepectoral Tissue Expander-Based Breast Reconstruction.

BACKGROUND: Prepectoral implant placement for postmastectomy breast reconstruction has increased in recent years. Benefits of prepectoral reconstruction may include lack of animation deformities and reduced postoperative pain, but its complication profile is currently unclear. This study aimed to examine the complication profile of prepectoral tissue expanders (TEs) to determine factors associated with TE loss. METHODS: A retrospective review was performed to identify all patients who underwent immediate prepectoral TE reconstruction from January 2018 to June 2021. The decision to use the prepectoral technique was based on mastectomy skin quality and patient comorbidities. Patient demographics, comorbidities, and operative details were evaluated. Outcomes of interest included TE loss, seroma, hematoma, infection/cellulitis, mastectomy skin flap necrosis requiring revision, and TE exposure. Logistic regression analysis was performed to identify factors associated with TE loss. RESULTS: The study identified 1225 TEs. The most frequent complications were seroma (8.7%, n = 106), infection/cellulitis (8.2%, n = 101), and TE loss (4.2%, n = 51). Factors associated with TE loss in the univariate analysis included ethnicity, history of smoking, body mass index, mastectomy weight, and neoadjuvant chemotherapy. In the multivariate regression analysis, only mastectomy weight had a positive association with TE loss (odds ratio, 1.001; p = 0.016). CONCLUSION: Prepectoral two-stage breast reconstruction can be performed safely with an acceptable early complication profile. The study data suggest that increasing mastectomy weight is the most significant factor associated with TE loss. Further research examining the quality of the soft tissue envelope and assessing patient-reported outcomes would prove beneficial.

Improving the Consent Process With an Informed Consent Video Prior to Outpatient Colonoscopy.

BACKGROUND AND AIMS: Informed consent should allow patients the appropriate time and conditions to make decisions about their care. However, consent is often obtained immediately prior to a colonoscopy. We conducted a quality improvement study to assess how a preprocedure consent video 2 days prior to an outpatient colonoscopy impacts patient satisfaction. METHODS: Patients undergoing outpatient colonoscopy at a large academic medical center opted in to a text messaging platform for procedural information. Our intervention was an informed consent video 2 days before the colonoscopy. Our primary outcome was a composite patient satisfaction score. Pre and postintervention scores were compared using ordinal or multinomial logistic models to calculate odds ratios (OR) or relative risk ratios and 95% confidence intervals (CI), adjusting for age and sex. RESULTS: 1109 and 1452 patients completed ≥1 survey question in the pre and postintervention phases, respectively. Overall patient satisfaction did not differ between groups [OR for a 1-point increment in satisfaction score between post- vs pre-intervention groups = 1.05; 95% CI: 0.90-1.22; P = .51]. Compared to preintervention, postintervention respondents were more likely to report higher satisfaction with time available to talk with their physician (OR of a 1-point increase in individual question response = 1.29; 95% CI: 1.09-1.54; P = .004). Compared to preintervention, more physicians in the postintervention phase rated satisfaction with consent process efficiency as "very satisfied" or "satisfied" (P < .001). CONCLUSION: An informed consent video prior to colonoscopy resulted in similar overall patient satisfaction. However, post-intervention, patients were more likely to report sufficient time to talk with their physician, and physicians reported higher satisfaction with consent efficiency.

Coronary Microcirculatory Dysfunction in People With HIV and Its Association With Antiretroviral Therapy.

BACKGROUND: HIV infection and abacavir-containing antiretroviral regimens are associated with vascular endothelial dysfunction and increased cardiovascular risk. Positron emission tomography (PET)-derived myocardial blood flow reserve (MBFR), the ratio of vasodilator stress to rest myocardial blood flow, is a well-validated measure of coronary microvascular health and marker of cardiovascular risk. Our objective was to compare MBFR among people with HIV (PWH) with matched non-HIV controls and to assess whether switching from dolutegravir/lamivudine/abacavir to the non-abacavir regimen bictegravir/emtricitabine/tenofovir alafenamide (TAF) would improve MBFR. METHODS AND RESULTS: Thirty-seven PWH were 1:2 matched on cardiovascular risk factors to 75 people without HIV, and MBFR corrected for differences in resting hemodynamics was compared in a cross-sectional design. PWH were majority men (68%) with a mean age of 56 years. Mean stress myocardial blood flow (1.83 mL/min per g [95% CI, 1.68-1.98] versus 2.40 mL/min per g [95% CI, 2.25-2.54]; P<0.001) and MBFR (2.18 [95% CI, 1.96-2.40] versus 2.68 [95% CI, 2.47-2.89]; P=0.002) was significantly lower in PWH than in people without HIV. In a single-arm, multicenter trial, a subset of 25 PWH who were virologically suppressed on dolutegravir/lamivudine/abacavir underwent positron emission tomography myocardial perfusion imaging at baseline and after switching to bictegravir/emtricitabine/TAF. MBFR was unchanged after switching to bictegravir/emtricitabine/TAF for a mean of 27 weeks (MBFR, 2.34 to 2.29; P=0.61), except in PWH with impaired MBFR at baseline (<2.00; N=6) in whom MBFR increased from 1.58 to 2.02 (P=0.02). CONCLUSIONS: PWH had reduced coronary microvascular function compared with controls without HIV. Coronary microvascular function did not improve after switching from dolutegravir/lamivudine/abacavir to bictegravir/emtricitabine/TAF.

Modular Titratable Polypills for Personalized Medicine and Simplification of Complex Medication Regimens.

Simplification of complex medication regimens in polypharmacy positively contributes to treatment adherence and cost-effective improved health outcomes. Even though fixed dose combination (FDC) drug products are the only currently available single dose poly-pill regimens, the lack of flexibility in dose adjustment of a single drug in the combination limits their efficacy. To fill the existing gap in drug dose personalization and simplification of complex medication regimens commonly encountered in the treatment of cardiovascular disease, tuberculosis, and tapering of corticosteroid therapy, a modular titratable polypill approach that simultaneously addresses both aspects is proposed. The polypill consists of modular units that contain different drugs at incremental or decremental doses to be assembled in a single titratable polypill at the required dose for each drug through a stacking or interlocking process. The variable dose (VD) modular tablets are subjected to quality control tests and found to comply to pharmacopeia's acceptance criteria and requirements specified in the respective drug monographs. A cost-effectiveness analysis is conducted supporting the VD strategy as cost-effective compared to the FDC strategy and more effective and less expensive than standard of care. The VD approach stands to enable pill burden reduction, ease of administration, enhancement of treatment adherence, and potential cost-saving benefits.

Visceral Adiposity Index as a Measure of Cardiovascular Disease in Persons With Human Immunodeficiency Virus.

Background: Persons with well-treated human immunodeficiency virus (HIV) demonstrate a 2-fold higher risk of cardiovascular disease (CVD), which may be related to excess visceral adipose tissue (VAT). The visceral adiposity index (VAI) is a score to approximate VAT by combining biochemical measures with anthropometrics without quantification by imaging. We evaluated VAI in association with cardiometabolic factors among persons with HIV (PWH). Methods: Forty-five PWH on antiretroviral therapy and virologically controlled with increased abdominal VAT (VAT area >110 cm2 on CT) and no known CVD were included. VAI was calculated using standard sex-specific formulas. Coronary plaque was assessed using coronary CT angiography. Results: Participants were predominantly male (73%), white (53%), and non-Hispanic (84%), with a mean age of 55 (standard deviation, 7) years. Among PWH, median VAI was calculated to be 4.9 (interquartile range [IQR], 2.8-7.3). Log VAI correlated with log VAT (r = 0.59, P < .0001) and anthropometric measures (body mass index: r = 0.36, P = .02; waist circumference: r = 0.43, P = .004; waist-to-hip ratio: r = 0.33, P = .03). Participants with coronary plaque had a higher VAI compared to those without coronary plaque (median, 5.3 [IQR, 3.4-10.5] vs 2.8 [IQR, 1.8-5.0]; P = .004). VAI (area under the curve = 0.760, P = .008) performed better than the atherosclerotic CVD risk score to predict the presence of plaque in receiver operating characteristic analyses. Conclusions: VAI may be a useful biomarker of metabolic dysfunction and increased CVD risk that may occur with VAT accumulation in PWH. Clinical Trials Registration: NCT02740179.

A Cohort Analysis of Early Outcomes After AlloDerm, FlexHD, and SurgiMend Use in Two-Stage Prepectoral Breast Reconstruction.

BACKGROUND: Acellular dermal matrix (ADM) is frequently utilized in prepectoral breast reconstruction, but few studies have examined the role of ADM type in complication risk. OBJECTIVES: This study was performed to determine the impact of ADM type on early complication rates in 2-stage alloplastic prepectoral breast reconstruction. METHODS: We performed a cohort examination of all patients who underwent mastectomy with immediate 2-stage alloplastic prepectoral breast reconstruction with ADM support at Memorial Sloan Kettering Cancer Center from 2018 to 2021. ADM types utilized included AlloDerm (LifeCell Corporation, Branchburg, NJ), FlexHD (MTF Biologics, Edison, NJ), and SurgiMend (Integra LifeSciences Corporation, Princeton, NJ). Complication rates based on the number of tissue expanders (TEs) were determined for each ADM type. Performance of multivariate logistic regression determined the impact of ADM type on complication risk after accounting for confounders. RESULTS: Overall, 726 patients (1054 TEs: 194 AlloDerm, 93 FlexHD, 767 SurgiMend) were included. The 3 cohorts differed in terms of mastectomy type (nipple-sparing: 23.5% of AlloDerm, 33.3% of FlexHD, 19.1% of SurgiMend, P = .038); ADM perforation (perforated: 94.8% of AlloDerm, 98.2% of FlexHD, 100% of SurgiMend, P < .001); and ADM size (AlloDerm: 153.2 cm2 [37.6], SurgiMend: 198.7 cm2 [10.4], FlexHD: 223.7 cm2 [37.9], P < .001). On univariate examination, no differences existed between ADM types for seroma, infection, exposure, malposition, or TE loss. Additionally, after adjustment for confounders with multivariate regression, no ADM type had higher odds of TE loss. CONCLUSIONS: In this large cohort of prepectoral reconstruction patients, ADM type did not significantly affect the risk of complications. Additional prospective studies are warranted to better evaluate ADM choice for prepectoral breast reconstruction.

Air versus Saline in Initial Prepectoral Tissue Expansion: A Comparison of Complications and Perioperative Patient-Reported Outcomes.

BACKGROUND: One option to optimize prepectoral tissue expander fill volume while minimizing stress on mastectomy skin flaps is to use air as an initial fill medium, with subsequent exchange to saline during postoperative expansion. The authors compared complications and early patient-reported outcomes (PROs) based on fill type in prepectoral breast reconstruction patients. METHODS: Prepectoral breast reconstruction patients who underwent intraoperative tissue expansion with air or saline from 2018 to 2020 were reviewed to assess fill-type utilization. The primary endpoint was expander loss; secondary endpoints included seroma, hematoma, infection/cellulitis, full-thickness mastectomy skin flap necrosis requiring revision, expander exposure, and capsular contracture. PROs were assessed with the BREAST-Q Physical Well-Being of the Chest scale 2 weeks postoperatively. Propensity-matching was performed as a secondary analysis. RESULTS: Of 560 patients (928 expanders) included in the analysis, 372 had devices initially filled with air (623 expanders), and 188 with saline (305 expanders). No differences were observed for overall rates of expander loss (4.7% versus 3.0%, P = 0.290) or overall complications (22.5% versus 17.7%, P = 0.103). No difference in BREAST-Q scores was observed ( P = 0.142). Utilization of air-filled expanders decreased substantially over the last study year. After propensity matching, no differences in loss, other complications, or PROs were observed across cohorts. CONCLUSIONS: Tissue expanders initially filled with air seem to have no significant advantage over saline-filled expanders in maintaining mastectomy skin flap viability or PROs, including after propensity matching. These findings can help guide choice of initial tissue expander fill type. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Do Resident Coaching Programs Benefit their Coaches? Impact of a Professional Development Coaching Program on The Coaches.

BACKGROUND: Coaching has been shown to decrease physician burnout; however, coachee outcomes have been the focus. We report the impact of coaching on women-identifying surgeons who participated as coaches in a 9-month virtual program. METHODS: A coaching program was implemented in the Association of Women Surgeons (AWS) to determine the effects of coaching on well-being and burnout from 2018 to 2020. AWS members volunteered and completed training in professional development coaching. Pre- and post-study measures were assessed, and bivariate analysis performed based on burnout and professional fulfillment score. RESULTS: Seventy-five coaches participated; 57 completed both pre- and post-study surveys. There were no significant changes in burnout or professional fulfillment including the Positive Emotion, Engagement, Relationship, Meaning, and Accomplishment scale, hardiness, self-valuation, coping, gratitude, or intolerance of uncertainty scores from baseline to post-survey. On bivariate analysis, hardiness was associated with lower burnout throughout the duration of the program. Coaches with lower burnout at the end of the program met with their coachee more frequently than coaches with higher burnout [mean (SD) 3.95(2.16) versus 2.35(2.13) p = 0.0099]. DISCUSSION: Burnout and professional fulfillment demonstrated no change in women surgeons who participated as professional development coaches. Those with lower burnout and higher professional fulfillment at the end of the program were found to have higher hardiness, which may be worth future investigation. CONCLUSIONS: Acquisition of coaching skills did not directly improve well-being in faculty who participated in a resident coaching program. Future studies would benefit from control groups and exploration of qualitative benefits of coaching.

Paravertebral Blocks in Tissue Expander Breast Reconstruction: Propensity-Matched Analysis of Opioid Consumption and Patient Outcomes.

BACKGROUND: The paravertebral block (PVB) is an adjunctive perioperative pain control method for patients undergoing breast reconstruction that may improve perioperative pain control and reduce narcotic use. This study determined the efficacy of preoperative PVBs for perioperative pain management in patients undergoing tissue expander breast reconstruction. METHODS: A retrospective review was performed of patients who underwent tissue expander breast reconstruction from December of 2017 to September of 2019. Two patients with PVBs were matched using propensity scoring to one no-block patient. Perioperative analgesic use, pain severity scores on days 2 to 10 after discharge, and BREAST-Q Physical Well-Being scores before surgery and at 2 weeks, 6 weeks, and 3 months after surgery were compared between the two groups. RESULTS: The propensity-matched cohort consisted of 471 patients (314 PVB and 157 no block). The PVB group used significantly fewer morphine milligram equivalents than the no-block group (53.7 versus 69.8; P < 0.001). Average daily postoperative pain severity scores were comparable, with a maximum difference of 0.3 points on a 0-point to 4-point scale. BREAST-Q Physical Well-Being scores were significantly higher for the PVB group than the no-block group at 6 weeks after surgery (60.6 versus 51.0; P = 0.015) but did not differ significantly at 2 weeks or 3 months after surgery. CONCLUSIONS: PVBs may help reduce perioperative opioid requirements but did not reduce pain scores after discharge when used as part of an expander-based reconstruction perioperative pain management protocol. Continued research should examine additional or alternative regional block procedures as well as financial cost and potential long-term impact of PVBs. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Quality of Life in Breast Reconstruction Patients after Irradiation to Tissue Expander: A Propensity-Matched Preliminary Analysis.

BACKGROUND: Tissue expanders (TEs) are routinely placed as a first step in breast reconstruction for women who require postmastectomy radiation therapy (PMRT). The final reconstruction can then be performed with implants or conversion to autologous tissues. The purpose of this study was to compare patient-reported outcomes and surgical complications in autologous (ABR) versus implant-based breast reconstruction (IBR) patients following TE-PMRT. METHODS: The authors performed a propensity score preliminary analysis (1:1 matching, no replacement) in patients undergoing ABR or IBR following TE-PMRT. Matched covariates included age, race/ethnicity, smoking status, body mass index, history of psychiatric diagnosis, and laterality of reconstruction. Outcomes of interest included complications and BREAST-Q scores for Satisfaction with Breasts, Physical Well-Being of the Chest, Sexual Well-Being, and Psychosocial Well-Being domains. RESULTS: Of 341 patients with TE-PMRT, a total of 106 patients were included in the matched analysis: 53 ABR patients and 53 IBR patients. ABR and IBR did not differ significantly in matched baseline, cancer, and surgical characteristics. ABR patients had higher scores for Satisfaction with Breasts (greater than the four-point minimal clinically important difference) at all postreconstruction time points compared with IBR patients ( P < 0.05). There were no significant postoperative differences in other BREAST-Q domains. The incidence of complications after definitive reconstruction did not differ significantly among cohorts. CONCLUSIONS: In this matched preliminary analysis, patients who underwent ABR following irradiation to a TE demonstrated superior satisfaction with breast scores compared with IBR patients. Higher powered matched studies are needed to improve shared decision-making for patients who require mastectomy and PMRT as part of their treatment. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Interpreting the BREAST-Q for Breast-Conserving Therapy: Minimal Important Differences and Clinical Reference Values.

BACKGROUND: The BREAST-Q is an important tool for evaluating patient satisfaction and quality of life in breast-conserving therapy (BCT) patients, but its clinical utility is limited by the lack of guidance on score interpretation. This study determines reference values and the minimal important difference (MID) for the BREAST-Q BCT module. METHODS: A retrospective review of BCT patients at Memorial Sloan Kettering Cancer Center from January 2011 to December 2021 was performed. Descriptive statistics were used to summarize median BREAST-Q scores. Distribution-based analyses estimated MIDs based on 0.2 standard deviation of baseline BREAST-Q scores and 0.2 standardized response mean of the difference between baseline and 1-year postoperative BREAST-Q scores. MIDs for different clinical groupings based on body mass index, radiation, and reexcision also were estimated. RESULTS: Overall, 8060 patients were included for determining reference values, and 5673 patients were included for estimating MIDs. Median BREAST-Q scores trended upwards and stabilized by 2 years after surgery for all domains except Physical Well-Being of the Chest, which decreased and stabilized by 2 years. A score interpretation tool, the Real-Time Engagement and Communication Tool, was created based on 25th percentile, median, and 75th percentile scores trajectories. All MID estimates ranged from 3 to 5 points; 4 points was determined to be appropriate for use in clinical practice and research. CONCLUSIONS: Reference values and MIDs are crucial to BREAST-Q score interpretation, which can lead to improved clinical evaluation and decision making and improved research methodology. Future research should validate this study's findings in different patient cohorts.

Reducing Opioid Overprescribing through Procedure-specific Prescribing Guidelines.

Despite advances in opioid-sparing pain management, postdischarge opioid overprescribing in plastic surgery remains an issue. Procedure-specific prescribing protocols have been implemented successfully in other surgical specialties but not broadly in plastic surgery. This study examined the efficacy of procedure-specific prescribing guidelines for reducing postdischarge opioid overprescribing. Methods: A total of 561 plastic surgery patients were evaluated retrospectively after a prescribing guideline, which recommended postdischarge prescription amounts based on the type of operation, was introduced in July 2020. Prescription and postdischarge opioid consumption amounts before (n = 428) and after (n = 133) guideline implementation were compared. Patient satisfaction and prescription frequency of nonopioid analgesia were also compared. Results: The average number of opioid pills per prescription decreased by 25% from 19.3 (27.4 OME) to 15.0 (22.7 OME; P = 0.001) after guideline implementation, with no corresponding decrease in the average number of postdischarge opioid pills consumed [10.6 (15.1 OME) to 8.2 (12.4 OME); P = 0.147]. Neither patient satisfaction with pain management (9.6-9.6; P > 0.99) nor communication (9.6-9.5; P > 0.99) changed. The rate of opioid-only prescription regimens decreased from 17.9% to 7.6% (P = 0.01), and more patients were prescribed at least two nonopioid analgesics (27.5% to 42.9%; P = 0.003). The rate of scheduled acetaminophen prescription, in particular, increased (54.7% to 71.4%; P = 0.002). Conclusions: A procedure-specific prescribing model is a straight-forward intervention to promote safer opioid-prescribing practices in plastic surgery. Its usage in clinical practice may lead to more appropriate opioid prescribing.

A Personalized Opioid Prescription Model for Predicting Postoperative Discharge Opioid Needs.

BACKGROUND: Opioid overprescribing after surgery is common. There is currently no universal predictive tool available to accurately anticipate postdischarge opioid need in a patient-specific manner. This study examined the efficacy of a patient-specific opioid prescribing framework for estimating postdischarge opioid consumption. METHODS: A total of 149 patients were evaluated for a single-center retrospective cohort study of plastic and reconstructive surgery patients. Patients with length of stay of 2 to 8 days and quantifiable inpatient opioid consumption (n = 116) were included. Each patient's daily postoperative inpatient opioid consumption was used to generate a personalized logarithmic regression model to estimate postdischarge opioid need. The validity of the personalized opioid prescription (POP) model was tested through comparison with actual postdischarge opioid consumption reported by patients 4 weeks after surgery. The accuracy of the POP model was compared with two other opioid prescribing models. RESULTS: The POP model had the strongest association (R2 = 0.899; P < 0.0001) between model output and postdischarge opioid consumption when compared to a procedure-based (R2 = 0.226; P = 0.025) or a 24-hour (R2 = 0.152; P = 0.007) model. Accuracy of the POP model was unaffected by age, gender identity, procedure type, or length of stay. Odds of persistent use at 4 weeks increased, with a postdischarge estimated opioid need at a rate of 1.16 per 37.5 oral morphine equivalents (P = 0.010; 95% CI, 1.04 to 1.30). CONCLUSIONS: The POP model accurately estimates postdischarge opioid consumption and risk of developing persistent use in plastic surgery patients. Use of the POP model in clinical practice may lead to more appropriate and personalized opioid prescribing.
