Use of patient-reported outcome measures after breast reconstruction in low- and middle-income countries: a scoping review.

BACKGROUND: Patient-reported outcome measures (PROMs) are increasingly administered in high-income countries to monitor health-related quality of life of breast cancer patients undergoing breast reconstruction. Although low- and middle-income countries (LMICs) face a disproportionate burden of breast cancer, little is known about the use of PROMs in LMICs. This scoping review aims to examine the use of PROMs after post-mastectomy breast reconstruction among patients with breast cancer in LMICs. METHODS: MEDLINE, Embase, Web of Science, CINAHL, and PsycINFO were searched in August 2022 for English-language studies using PROMs after breast reconstruction among patients with breast cancer in LMICs. Study screening and data extraction were completed. Data were analyzed descriptively. RESULTS: The search produced 1024 unique studies, 33 of which met inclusion criteria. Most were observational (48.5%) or retrospective (33.3%) studies. Studies were conducted in only 10 LMICs, with 60.5% in China and Brazil and none in low-income countries. Most were conducted in urban settings (84.8%) and outpatient clinics (57.6%), with 63.6% incorporating breast-specific PROMs and 33.3% including breast reconstruction-specific PROMs. Less than half (45.5%) used PROMs explicitly validated for their populations of interest. Only 21.2% reported PROM response rates, ranging from 43.1 to 96.9%. Barriers and facilitators of PROM use were infrequently noted. CONCLUSIONS: Despite the importance of PROM collection and use in providing patient-centered care, it continues to be limited in middle-income countries and is not evident in low-income countries after breast reconstruction. Further research is necessary to determine effective methods to address the challenges of PROM use in LMICs.

Reconstruction of oncologic upper extremity defects with fibula free flaps has high union rates and excellent functional outcomes.

BACKGROUND: Limb salvage has better functional outcomes than amputation in the upper extremity. This can however be challenging after bony tumor resections. METHODS: This is a retrospective case series of patients who underwent humerus, ulna, or radius reconstruction with a fibula free flap. Data were collected on demographics, oncologic history, surgical details, and complications. Functional outcome measures included the patient's ability to perform activities of daily living (ADL), presence of pain, and musculoskeletal tumor society (MSTS) score. RESULTS: Over a 25-year period, 38 reconstructions were performed. The flap success rate was 97.5%. Bony union was obtained in 19 of 19 (100%) forearm reconstructions and in 15 of 19 (79%) humerus reconstructions (p = 0.10). All 19 forearm reconstruction patients and 18/19 humerus reconstruction patients were able to perform ADLs with no pain or only occasional pain. The MSTS scores were not significantly different between the humerus and forearm cohorts (27.1 vs. 27.3, p = 0.68). Functional outcomes were significantly better in limbs that achieved union (p < 0.001). Recipient and donor site complications occurred in 10 (26.3%) and 5 (13%) patients, respectively. CONCLUSIONS: Oncologic upper-extremity reconstruction with fibula free flaps has excellent functional outcomes. Bone union is a predictor of superior limb function.

A Fast-Track Pathway for Emergency General Surgery at an Academic Medical Center.

BACKGROUND: Fast Track Pathways (FTP) directed at reducing length of stay (LOS) and overall costs are being increasingly implemented for emergency surgeries. The purpose of this study is to evaluate implementation of a FTP for Emergency General Surgery (EGS) at an academic medical center (AMC). METHODS: The study included 165 patients at an AMC between 2016 and 2018 who underwent laparoscopic appendectomy (LA), laparoscopic cholecystectomy (LC), or laparoscopic inguinal hernia repair (LI). The FTP group enrolled 89 patients, and 76 controls prior to FTP implementation were evaluated. Time to surgery (TTS), LOS, and post-operative LOS between groups were compared. Direct costs, reimbursements, and patient reported satisfaction (satisfaction 1 = never, 4 = always) were also studied. RESULTS: The sample was 60.6% female, with a median age of 40 years. Case distribution differed slightly (56.2% versus 42.1% LA, 40.4% versus 57.9% LC, FTP versus control), but TTS was similar between groups (11h39min versus 10h02min, P = 0.633). LOS was significantly shorter in the FTP group (15h17min versus 29h09min, P < 0.001), reflected by shorter post-operative LOS (3h11min versus 20h10min, P< 0.001), fewer patients requiring a hospital bed and overnight stay (P < 0.001). Direct costs were significantly lower in the FTP group, reimbursements were similar (P < 0.001 and P = 0.999 respectively), and average patient reported satisfaction was good (3.3/4). CONCLUSION: In an era focused on decreasing cost, optimizing resources, and ensuring patient satisfaction, a FTP can play a significant role in EGS. At an AMC, an EGS FTP significantly decreased LOS, hospital bed utilization while not impacting reimbursement or patient satisfaction.

A Translational Model for Venous Thromboembolism: MicroRNA Expression in Hibernating Black Bears.

BACKGROUND: Hibernating American black bears have significantly different clotting parameters than their summer active counterparts, affording them protection against venous thromboembolism during prolonged periods of immobility. We sought to evaluate if significant differences exist between the expression of microRNAs in the plasma of hibernating black bears compared with their summer active counterparts, potentially contributing to differences in hemostasis during hibernation. MATERIALS AND METHODS: MicroRNA sequencing was assessed in plasma from 21 American black bears in summer active (n = 11) and hibernating states (n = 10), and microRNA signatures during hibernating and active state were established using both bear and human genome. MicroRNA targets were predicted using messenger RNA (mRNA) transcripts from black bear kidney cells. In vitro studies were performed to confirm the relationship between identified microRNAs and mRNA expression, using artificial microRNA and human liver cells. RESULTS: Using the bear genome, we identified 15 microRNAs differentially expressed in the plasma of hibernating black bears. Of these microRNAs, three were significantly downregulated (miR-141-3p, miR-200a-3p, and miR-200c-3p), were predicted to target SERPINC1, the gene for antithrombin, and demonstrated regulatory control of the gene mRNA expression in cell studies. CONCLUSIONS: Our findings suggest that the hibernating black bears' ability to maintain hemostasis and achieve protection from venous thromboembolism during prolonged periods of immobility may be due to changes in microRNA signatures and possible upregulation of antithrombin expression.

Treatment of Facial Fractures at a Level 1 Trauma Center: Do Medicaid and Non-Medicaid Enrollees Receive the Same Care?

BACKGROUND: Timing of surgical treatment of facial fractures may vary with the patient age, injury type, and presence of polytrauma. Previous studies using national data sets have suggested that trauma patients with government insurance experience fewer operations, longer length of hospital stay (LOS), and worse outcomes compared with privately insured patients. The objective of this study is to compare treatment of facial fractures in patients with and without Medicaid insurance (excluding Medicare). METHODS: All adults with mandibular, orbital, and midface fractures at a Level 1 Trauma Center between 2009 and 2018 were included. Statistical analyses were performed to assess the differences in the frequency of surgery, time to surgery (TTS), LOS, and mortality based on insurance type. RESULTS: The sample included 1541 patients with facial fractures (mandible, midface, orbital), of whom 78.8% were male, and 13.1% (208) were enrolled in Medicaid. Mechanism of injury was predominantly assault for Medicaid enrollees and falls or motor vehicle accidents for non-Medicaid enrollees (P < 0.001). Patients with mandible and midface fractures underwent similar rates of surgical repair. Medicaid enrollees with orbital fractures underwent less frequent surgery for facial fractures (24.8% versus 34.7%, P = 0.0443) and had higher rates of alcohol and drug intoxication compared with non-Medicaid enrollees (42.8% versus 31.6%, P = 0.008). TTS, LOS, and mortality were similar in both groups with facial fractures. CONCLUSIONS: Overall, the treatment of facial fractures was similar regardless of the insurance type, but Medicaid enrollees with orbital fractures experienced less frequent surgery for facial fractures. Further studies are needed to identify specific socioeconomic and geographic factors contributing to these disparities in care.

Treatment of Acute Cholecystitis: Do Medicaid and Non-Medicaid Enrolled Patients Receive the Same Care?

BACKGROUND: Nationally, Medicaid enrollees with emergency surgical conditions experience worse outcomes overall when compared with privately insured patients. The goal of this study is to investigate disparities in the treatment of cholecystitis based on insurance type and to identify contributing factors. METHODS: Adults with cholecystitis at a safety-net hospital in Central Massachusetts from 2017-2018 were included. Sociodemographic and clinical characteristics were compared based on Medicaid enrollment status (Medicare excluded). Univariate and multivariate analyses were used to compare the frequency of surgery, time to surgery (TTS), length of stay (LOS), and readmission rates between groups. RESULTS: The sample (n = 203) included 69 Medicaid enrollees (34%), with a mean age of 44.4 years. Medicaid enrollees were younger (p = 0.0006), had lower levels of formal education (high school diploma attainment, p < 0.0001), were more likely to be unmarried (p < 0.0001), Non-White (p = 0.0012), and require an interpreter (p < 0.0001). Patients in both groups experienced similar rates of laparoscopic cholecystectomy, TTS, and LOS; however, Medicaid enrollees experienced more readmissions within 30 days of discharge (30.4% vs 17.9%, p < 0.001). CONCLUSION: Despite anticipated population differences, the treatment of acute cholecystitis was similar between Medicaid and Non-Medicaid enrollees, with the exception of readmission. Further research is needed to identify patient, provider, and/or population factors driving this disparity.

Treatment of appendicitis: Do Medicaid and non-Medicaid-enrolled patients receive the same care?

BACKGROUND: Studies using national data sets have suggested that insurance type drives a disparity in the care of emergency surgery patients. Large databases lack the granularity that smaller, single-institution series may provide. The goal of this study is to identify factors that may account for differences in care between Medicaid and non-Medicaid enrollees with appendicitis in central Massachusetts. METHODS: All adult patients with acute appendicitis in an academic medical center between 2010 and 2018 were included. Sociodemographic and clinical characteristics were compared according to Medicaid enrollment status. Analyses were performed to assess differences in the frequency of operative treatment, time to surgery, length of stay, and rates of readmission. RESULTS: The sample included 1,257 patients, 10.7% of whom (n = 135) were enrolled in Medicaid. The proportions of patients presenting with perforated appendicitis (28.9% vs 31.2%, P = .857) and undergoing laparoscopic appendectomy (96.3% vs 90.7%, P = .081) were similar between the 2 groups, as were length of stay (20 hours 30 minutes versus 22 hours 38 minutes, P = .109) and readmission rates (17.8% vs 14.5%, P = .683). Medicaid enrollees did experience somewhat greater time to surgery (6 hours 47 minutes versus 4 hours 49 minutes, P < .001). CONCLUSION: Despite anticipated differences in population, the treatment of appendicitis was similar between Medicaid and non-Medicaid enrollees. Medicaid enrollees experienced greater time to surgery; however, further studies are needed to explain this disparity in care.
