RESUMO

Importance: Hospice care enhances quality of life for people with terminal illness and is most beneficial with longer length of stay (LOS). Most hospice research focuses on the Medicare-insured population. Little is known about hospice use for the racially and ethnically diverse, low-income Medicaid population. Objective: To compare hospice use and hospice LOS by race and ethnicity among Medicaid-only individuals and those with dual eligibility for Medicare and Medicaid (duals) in the Connecticut Medicaid program who died over a 4-year period. Design, Setting, and Participants: This retrospective population-based cohort study used Medicaid and traditional Medicare enrollment and claims data for 2015 to 2020. The study included Connecticut Medicaid recipients with at least 1 of 5 most common hospice diagnoses who died from 2017 to 2020. Exposure: Race and ethnicity. Main Outcomes and Measures: Hospice use (yes/no) and hospice LOS (1-7 days vs ≥8 days.) Covariates included sex, age, and nursing facility stay within 60 days of death. Results: Overall, 2407 and 23 857 duals were included. Medicaid-only decedents were younger (13.8% ≥85 vs 52.5%), more likely to be male (50.6% vs 36.4%), more racially and ethnically diverse (48.7% non-Hispanic White vs 79.9%), and less likely to have a nursing facility stay (34.9% vs 56.1%). Race and ethnicity were significantly associated with hospice use and LOS in both populations: non-Hispanic Black and Hispanic decedents had lower odds of using hospice than non-Hispanic White decedents, and Hispanic decedents had higher odds of a short LOS. In both populations, older age and female sex were also associated with more hospice use. For duals only, higher age was associated with lower odds of short LOS. For decedents with nursing facility stays, compared with those without, Medicaid-only decedents had higher odds of using hospice (odds ratio [OR], 1.49; 95% CI, 1.24-1.78); duals had lower odds (OR, 0.60; 95% CI, 0.57-0.63). Compared with decedents without nursing facility stays, duals with a nursing facility stay had higher odds of short LOS (OR, 2.63; 95% CI, 2.43-2.85). Conclusions and Relevance: Findings raise concerns about equity and timing of access to hospice for Hispanic and non-Hispanic Black individuals in these understudied Medicaid populations. Knowledge about, access to, and acceptance of hospice may be lacking for these low-income individuals. Further research is needed to understand barriers to and facilitators of hospice use for people with nursing facility stays.

RESUMO

BACKGROUND: Rhinoplasty, a leading cosmetic surgical procedure, often involves the use of opioids for postoperative pain management. This raises concerns due to potential opioid side effects and overprescription. Liposomal bupivacaine offers a promising alternative, but its efficacy in rhinoplasty remains under-investigated. This study assesses the impact of liposomal bupivacaine on postoperative pain and opioid consumption following rhinoplasty. METHODS: A retrospective study was conducted on patients undergoing rhinoplasty between January 2014 and September 2020. Postoperative pain scores were assessed at intervals up to 16 h, and opioid consumption was monitored. Patients were stratified into two groups: those receiving postoperative liposomal bupivacaine (Group 1) and those who did not (Group 2). RESULTS: No significant disparities in demographics or surgical specifics were identified between groups. Group 1 consistently reported lower pain scores, notably at 30 min (1.4 vs. 3.7, p = 0.0006) and 2 h (2.2 vs. 3.38, p = 0.0417). Cumulatively, Group 1's average pain score was 2.4, significantly lower than Group 2's 3.4 (p = 0.0023). Group 1 also demonstrated reduced opioid consumption, with oxycodone and oral morphine equivalent (OME) intake being notably lower (p = 0.005 and p = 0.0428, respectively). CONCLUSION: Liposomal bupivacaine presents as an efficacious alternative for post-rhinoplasty pain management, reducing both perceived pain and opioid consumption. While promising, the findings necessitate validation through larger, prospective studies considering the inherent limitations of this preliminary investigation. This study evaluates the efficacy of liposomal bupivacaine as a pain management strategy in postoperative care for rhinoplasty and septorhinoplasty procedures, with the potential to reduce reliance on opioids. The findings indicate that patients receiving liposomal bupivacaine experienced significantly lower pain scores postoperatively and less overall opioid consumption, thereby enhancing patient comfort and safety.

RESUMO

OBJECTIVE: To describe the outcomes of patients undergoing open stapler versus transoral rigid and flexible endoscopic therapies for symptomatic Zenker's diverticulum. STUDY DESIGN: Single institution retrospective review. SETTING: Tertiary care academic hospital. METHODS: We retrospectively evaluated the outcomes of 424 consecutive patients who underwent Zenker's diverticulotomy via an open stapler, rigid endoscopic CO2 laser, rigid endoscopic stapler, rigid endoscopic harmonic scalpel, or flexible endoscopic technique from January 2006 to December 2020. RESULTS: A total of 424 patients (173 females, mean age 73.1 ± 11.2 years) from a single institution were included. A total of 142 patients (33%) underwent endoscopic laser treatment, 33 (8%) underwent endoscopic harmonic scalpel, 92 (22%) underwent endoscopic stapler, 70 (17%) underwent flexible endoscopic, and 87 (20%) underwent open stapler. All open and rigid endoscopic procedures and most of the flexible endoscopic procedures (65%) were performed under general anesthesia. The flexible endoscopic group had a higher percentage of procedure-related perforation, defined as subcutaneous emphysema or contrast leak on imaging (14.3%). The recurrence rates were higher in the harmonic stapler, flexible endoscopic, and endoscopic stapler groups at 18.2%, 17.1%, and 17.4%, respectively, and lower in the open group (1.1%). Length of hospital stay and return to oral intake were similar among groups. CONCLUSION: The flexible endoscopic technique was associated with the highest rate of procedure-related perforation, while the endoscopic stapler had the lowest number of procedural complications. Recurrence rates were higher among the harmonic stapler, flexible endoscopic, and endoscopic stapler groups and lower in the endoscopic laser and open groups. Prospective comparative studies with long-term follow-up are needed.

RESUMO

OBJECTIVE: Flexible endoscopic Zenker's diverticulotomy (FEZD) is a procedure performed primarily by gastroenterologists for treatment of symptomatic Zenker's diverticulum (ZD). Given the lack of prior investigations with large sample sizes, we report on one of the largest series of patients who underwent FEZD. METHODS: A review of patients who underwent FEZD at our institution from 2006 to 2021 was performed. Data were abstracted for patient demographics, clinical features, procedural characteristics, adverse events, and outcomes. RESULTS: A total of 75 patients (37 women) with mean age of 77.9 (33-102) years and mean (range) follow-up of 1.1 (0-13.2) years were identified. 67.9 % of FEZD cases were performed under general anesthesia. The mean procedure time was 37.1 min. Same day discharge and resumption of oral intake was seen in 56.4 % and 57.1 % of cases, respectively. Adverse events included intraprocedural bleeding (15.7 %) controlled with endoscopic means, infection (4.8 %) exclusively managed with antibiotics in all but one case, subcutaneous emphysema (2.4 %), and perforation (10.7 %) conservatively managed in all but one case. 97.6 % of patients had sustained subjective improvement in symptoms following their procedure. Fifteen patients (20 %) experienced recurrence after undergoing initial FEZD-26.7 % percent of whom were sufficiently treated with repeat FEZDs. Younger age was associated with recurrence (p < 0.01). CONCLUSION: FEZD is an effective, safe procedure for the management of symptomatic ZD. It is a viable alternative for patients in whom otorhinolaryngological procedures via rigid endoscopy are not an option.

RESUMO

INTRODUCTION: Patients with primary hyperparathyroidism (1HPT) undergoing reoperative or subtotal parathyroidectomy (PTX) may undergo autotransplantation (ATX) when the viability of remaining tissue is unknown. This study aims to identify whether intraoperative parathyroid hormone levels (IOPTH) can determine ATX candidacy. METHODS: Patients with 1HPT who underwent PTX with ATX at our institution were identified. IOPTH and PTH values within 24 h, 2-4 weeks, and >1 month postoperative were analyzed. Patients were classified as either a candidate for ATX (low PTH after 2-4 weeks) or not a candidate based on postoperative PTH (normal PTH after 2-4 weeks). Associations of ATX candidate status with demographic and clinical attributes were studied. RESULTS: 268 had a reoperative (49%) or subtotal PTX with ATX. 151 had data for PTH analysis, and 21 (14%) were identified as candidates for ATX. The mean % decline in IOPTH from baseline to 20 min post-excision was 51% in noncandidates vs 73% in candidates (P = .002). The mean change in IOPTH from baseline to final was 52% in noncandidates and 83% in candidates (P = .009). A decrease in IOPTH from baseline to 20 min post-excision of 23.4% or greater or a final PTH of 52 pg/mL or less would be an indication for ATX. Of the 21 who needed an ATX, it failed in 10. CONCLUSION: Parathyroid ATX is frequently unnecessary, and the viability is less than expected. While candidates for ATX have a greater IOPTH % decline at all points during surgery and a lower final IOPTH, the clinical practicality of using IOPTH to determine ATX candidacy is limited.

RESUMO

BACKGROUND: At some US Academic Health Centers (AHCs), patients with predominantly Medicaid insurance are seen in one clinic and patients with other insurance are seen in another. The extent of this practice and implications are unknown. OBJECTIVE: To estimate the proportion of AHCs that have at least two primary care internal medicine clinics that differ substantially in proportion of patients with Medicaid and to compare patient demographic, staffing, and operational features. PARTICIPANTS: General internal medicine chiefs and clinic directors at 40 randomly selected US AHCs plus the top 10 AHCs in terms of NIH funding. MAIN MEASURE: An AHC was classified as maintaining clinics that differed substantially in the proportion of patients with Medicaid if any two differed by ≥ 40% (absolute). Other criteria were used for pre-specified secondary analyses (e.g., ≥ 30%). KEY RESULTS: Thirty-nine of 50 AHCs (78%) participated. Four of 39 (10%; 95% CI, 3 to 24%) had two clinics differing by ≥ 40% in the proportion of patients with Medicaid, eight (21%; 95% CI, 9 to 36%) had clinics differing by ≥ 30%, and 15 (38%; 95% CI, 23 to 55%) had clinics differing by ≥ 20%. Clinics with more patients with Medicaid by any of the three criteria were more likely to employ resident physicians as providers of longitudinal care (with faculty supervision) and more likely to have patients who were Black or Hispanic. CONCLUSIONS: Some US AHCs maintain separate clinics defined by the proportion of patients with Medicaid. Clinics with a higher proportion of patients insured by Medicaid are more likely to employ residents (with faculty oversight), feature residents as providers of longitudinal care, and serve patients who are Black and Hispanic. Further research is needed to understand why some AHCs have primary care clinics distinguishable by insurance mix with the goal of ensuring that racism and discrimination are not root causes.

RESUMO

OBJECTIVE: To compare the incidence of glottic stenosis in idiopathic subglottic stenosis (iSGS) patients with no prior surgical intervention to those with a history of endoscopic dilation and characterize the incidence of glottic involvement, changes in scar length, and progression of scar toward glottis following laser wedge excision (LWE). METHODS: A retrospective review of iSGS patients who underwent LWE between 2002 and 2021 was performed. Patients without prior airway surgery were labeled LWE primary (LWEP) and operative findings for LWEP patients were reviewed for glottic involvement, scar length (DL ), and distance from the glottis to superior-most aspect of scar (DGS ). Rates (in mm/procedure) of DΔL , reflecting an increase in length, and D-ΔGS , reflecting proximal migration, were calculated by dividing DΔL and D-ΔGS by the number of LWE procedures. RESULTS: 213 iSGS patients underwent LWE, with 132 being LWEP patients. LWEP had a lower incidence of baseline glottic involvement (n = 6, 4.5%) than LWE secondary (LWES; n = 6, 7.5%). Four new cases of glottic involvement were noted in LWEP patients following LWE, with only one being clinically significant resulting in permanently decreased vocal fold mobility. With each procedure, scar length increased by 1.0 mm and DGS decreased by 0.7 mm, reflecting a migration or decrease in DGS of 9.5% with each procedure with respect to initial DGS . Overall rates of glottic stenosis following operations were similar between LWEP and LWES cohorts, 7.6% and 7.5% respectively. CONCLUSION: There appears to be a low risk of glottic involvement resulting from the LWE procedure in iSGS patients. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:875-882, 2023.

RESUMO

OBJECTIVES: Endoscopic laser wedge excision (LWE) is an effective treatment option for idiopathic subglottic stenosis (iSGS); however, data regarding complications following LWE are limited. The aim of the following analysis was to provide a review of frequency and type of complications that occur with LWE in patients with iSGS. STUDY DESIGN: Retrospective review. METHODS: Patients with iSGS undergoing LWE between January 2002 and September 2021 were performed. Demographic data were recorded. Complications were stratified into major and minor categories. The frequency of these complications and the respective treatment for them was analyzed. RESULTS: 212 patients within the study period underwent a total of 573 LWE procedures. All but two patients were female, with a median age of 54 years at time of LWE. Of these patients, 43 (20 %) patients experienced a complication. Of these, only 7 (15 %) of the reported complications were considered major while the rest were minor in nature. Major complications included 3 cases of post-operative hemoptysis, 1 case of tracheitis, and 3 cases of reduced vocal fold hypomobility with concurrent glottic stenosis. Minor complications consisted of 2 cases of tooth fracture and 34 cases of tongue paresthesia post-operatively that was self-limited. There were no mortalities. CONCLUSION: Major complications occur in <5 % of LWE procedures based off the analysis. All major complications were managed without significant long-term morbidity. Minor complications with the LWE are self-limited in nature. Our data supports the LWE as a safe treatment option for iSGS.

RESUMO

Unmet dermatologic needs of the uninsured patient population are important to identify and address, especially as the COVID-19 pandemic has introduced additional barriers of access to care. We describe the successful collaboration between a student-run free clinic and dermatology practice since 2012, highlighting excellent time to appointment intervals and resolution rates as well as the associated modest financial cost. We believe that the information provided in our report may serve as a proof of concept and facilitate the implementation of such collaborations throughout the United States.

RESUMO

As the COVID-19 pandemic began, the residents from our ambulatory clinics were pulled to cover the increasing numbers of hospitalised patients. To provide care for our 40 000 patients, without resident support, we needed to develop quickly a new culture of communication and innovation. We accomplished this by regular, transparent meetings with senior leadership and key stakeholders who were empowered to make rapid decisions. We then convened regular meetings with clinic leadership and frontline providers to receive feedback and implement new practices. These rapid meeting cycles allowed for a nimble response to a changing landscape. We optimised our video-conferencing and telehealth services, reached out to our most vulnerable patients and engaged other providers and medical students who were not engaged in patient care due to social isolation practices. We discuss the implications of these innovations on our future practice.

RESUMO

BACKGROUND: Transitions from hospital to home in older patients are a high-risk period for adverse outcomes in a population that may have more challenges navigating the healthcare system. There is little information about the association of patient-reported quality of hospital discharge processes with clinical outcomes. OBJECTIVES: We evaluated whether patient-reported quality of hospital discharge processes was associated with emergency department utilization and rehospitalization within 30 days of discharge after hospitalization for acute myocardial infarction (AMI) in older adults. DESIGN: Multi-center, prospective cohort study. PATIENTS: The ComprehenSIVe Evaluation of Risk Factors in Older Patients with Acute Myocardial Infarction (SILVER-AMI) study was a longitudinal study of 3006 adults age 75 and older hospitalized with AMI recruited from 94 academic and community hospitals from across the USA. INTERVENTION: N/A MAIN MEASURES: Patients answered a subset of questions from the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey. Readmissions and emergency department utilization within 30 days of discharge were ascertained through medical record review. KEY RESULTS: A total of 2132 patients were included in the study. Patients' median age was 81 years and the response rate to the survey of discharge quality was 87%. Patients who reported being asked about having the help they needed at home were significantly less likely to have emergency room utilization within 30 days of discharge in both the unadjusted (0.65, 95% CI 0.43-0.99) and adjusted (0.65, 95% CI 0.42-0.997) models, though there was no significant association with readmission. CONCLUSION: Report of an assessment of help needed at home during hospitalization was associated with lower post-discharge emergency department utilization. Efforts to improve outcomes after hospital discharge in older patients may benefit from greater focus on assessing need of help at home.

RESUMO

BACKGROUND: The year-long position of chief medical resident is a time-honored tradition in the United States that serves to provide the trainee with an opportunity to gain further skills as a clinician, leader, teacher, liaison, and administrator. However, in most training programs in the developing world, this role does not exist. OBJECTIVES: We sought to develop a collaborative program to train the first medical chief residents for the University of Rwanda and to assess the impact of the new chief residency on residency training, using questionnaires and qualitative interviews with Rwandan faculty, chief residents, and residents. METHODS: The educational context and the process leading up to the appointment of Rwandan chief residents, including selection, job description, and necessary training (in the United States and Rwanda), are described. One year after implementation, we used a parallel, mixed methods approach to evaluate the new chief medical resident program through resident surveys as well as semistructured interviews with key informants, including site chief residents, chief residents, and faculty. We also observed chief residents and site chief residents at work and convened focus groups with postgraduate residents to yield additional qualitative information. RESULTS: Rwandan faculty and residents generally felt that the new position had improved the educational and administrative structure of the teaching program while providing a training ground for future academicians. CONCLUSIONS: A collaborative training program between developing and developed world academic institutions provides an efficient model for the development of a new chief residency program in the developing world.

RESUMO

BACKGROUND: Workforce projections indicate a potential shortage of up to 31,000 adult primary care providers by the year 2025. Approximately 80 % of internal medicine residents and nearly two-thirds of primary care internal medicine residents do not plan to have a career in primary care or general internal medicine. OBJECTIVE: We aimed to explore contextual and programmatic factors within primary care residency training environments that may influence career choices. DESIGN: This was a qualitative study based on semi-structured, in-person interviews. PARTICIPANTS: Three primary care internal medicine residency programs were purposefully selected to represent a diversity of training environments. Second and third year residents were interviewed. APPROACH: We used a survey guide developed from pilot interviews and existing literature. Three members of the research team independently coded the transcripts and developed the code structure based on the constant comparative method. The research team identified emerging themes and refined codes. ATLAS.ti was used for the analysis. KEY RESULTS: We completed 24 interviews (12 second-year residents, and 12 third-year residents). The age range was 27-39 years. Four recurrent themes characterized contextual and programmatic factors contributing to residents' decision-making: resident expectations of a career in primary care, navigation of the boundary between social needs and medical needs, mentorship and perceptions of primary care, and structural features of the training program. CONCLUSIONS: Addressing aspects of training that may discourage residents from careers in primary care such as lack of diversity in outpatient experiences and resident frustration with their inability to address social needs of patients, and strengthening aspects of training that may encourage interests in careers in primary care such as mentorship and protected time away from inpatient responsibilities during primary care rotations, may increase the proportion of residents enrolled in primary care training programs who pursue a career in primary care.

RESUMO

PURPOSE: To determine the difference between the predicted and postoperative refraction in eyes after implantation of the Mentor MemoryLens intraocular lens (IOL) and compare these results with those of 2 other types of foldable IOLs implanted by the same surgeons. SETTING: Community-based group practice ophthalmology clinic. METHODS: All operated eyes (341) of all patients who had routine phacoemulsification with implantation of a MemoryLens IOL performed by 1 of 2 surgeons were evaluated retrospectively. The predicted refractive error and actual postoperative refractive error were compared in each eye in the MemoryLens group and in 2 smaller control groups with an AcrySof acrylic (Alcon) or SI-40 silicone (Allergan Medical Optics) IOL implanted by the same surgeons using identical technique and IOL calculation parameters. Patients in whom the difference between the predicted and actual postoperative refraction fell significantly outside expected parameters were rechecked with repeat axial length and keratometric readings, and these measurements were used to back-calculate the effective in vivo IOL power. RESULTS: The MemoryLens group had significantly greater variability in postoperative refractive results from those predicted by the Hoffer program than the 2 control groups. The postoperative refractive error in the MemoryLens group differed from +1.50 to -5.50 diopters (D) from that predicted by the IOL calculation formulas. When the outlier groups (ie, greater than +0.50 D or less than -1.00 D from predicted refractive error) were evaluated and compared to the rest of the MemoryLens group and the 2 control groups, no significant difference in axial length, keratometric measurements, operative surgeon, surgical technique, or patient age was found. Repeat axial length and keratometric measurements in the outlier group were not significantly different from those in the same eyes preoperatively. Back-calculation using postoperative axial length and keratometric measurements in the highly myopic outlier group showed that the mean difference between the labeled IOL power and actual in vivo IOL power in the outlier group was -3.08 D (range -1.98 to -7.54 D). The best corrected visual acuity was not affected in patients in the outlier groups despite the refractive variability. CONCLUSION: The variation in postoperative refractive results in the MemoryLens group was significantly greater than in the 2 other foldable IOL groups.
