Background: People who inject drugs (PWID) are at high risk for opioid overdose and infectious diseases including HIV. We piloted PARTNER UP, a telemedicine-based program to provide PWID with medication for opioid use disorder (MOUD) with buprenorphine/naloxone (bup/nx) and oral pre-exposure prophylaxis (PrEP) with tenofovir disoproxil fumarate/emtricitabine through two syringe services programs (SSP) in North Carolina. We present overall results from this project, including participant retention rates and self-reported medication adherence., Methods: Study participants met with a provider for an initial in-person visit at the SSP, followed by weekly telemedicine visits in month 1 and then monthly until program end at month 6. Participants were asked to start both MOUD and PrEP at initiation but could choose to discontinue either at any point during the study. Demographics and health history including substance use, sexual behaviors, and prior use of MOUD/PrEP were collected at baseline. Follow-up surveys were conducted at 3- and 6-months to assess attitudes towards MOUD and PrEP, change in opioid use and sexual behaviors, and for self-reported medication adherence. Participant retention was measured by completion of visits; provider notes were used to assess whether the participant reported continuation of medication., Results: Overall, 17 persons were enrolled and started on both bup/nx and PrEP; the majority self-identified as white and male. At 3 months, 13 (76%) remained on study; 10 (77%) reported continuing with both MOUD and PrEP, 2 (15%) with bup/nx only, and 1 (8%) with PrEP only. At 6 months, 12 (71%) remained on study; 8 (67%) reported taking both bup/nx and PrEP, and 4 (33%) bup/nx only. Among survey participants, opioid use and HIV risk behaviors decreased. Nearly all reported taking bup/nx daily; however, self-reported daily adherence to PrEP was lower and declined over time. The most common reason for not continuing PrEP was feeling not at risk for acquiring HIV., Conclusions: Our study results show that MOUD and PrEP can be successfully administered via telemedicine in SSPs. PrEP appears to be a lower priority for participants with decreased continuation and adherence. Low perception of HIV risk was a reason for not continuing PrEP, possibly mitigated by MOUD use. Future studies including helping identify PWID at highest need for PrEP are needed., Trial Registration: Providing Suboxone and PrEP Using Telemedicine, NCT04521920.

Background: Medication for opioid use disorder (MOUD) reduces mortality, but few patients access MOUD. At a Federally Qualified Health Center (FQHC), we implemented a low barrier model of MOUD, including same-day MOUD initiation and a harm reduction philosophy., Objective: To investigate whether low barrier MOUD improved retention in care compared to traditional treatment., Design and Participants: Retrospective cohort study of patients with at least one visit seeking MOUD at the FQHC during a historical control period (3/1/2018-3/31/2019) and a low barrier intervention period (11/1/2019-7/31/2020)., Main Measures: Primary outcomes were any MOUD prescription within 6 months of the index visit and 3- and 6-month retention in treatment without care gap, with care gap defined as 60 consecutive days without a visit or prescription. Secondary outcomes were all-cause hospitalization and emergency department visit within 6 months of the index visit., Key Results: Baseline characteristics were similar between the intervention (n = 113) and control (n = 90) groups, except the intervention group had higher rates of uninsured, public insurance and diabetes. Any MOUD prescription within 6 months of index visit was higher in the intervention group (97.3% vs 70%), with higher adjusted odds of MOUD prescription (OR = 4.01, 95% CI 2.08-7.71). Retention in care was similar between groups at 3 months (61.9% vs 60%, aOR = 1.06, 95% CI 0.78-1.44). At 6 months, a higher proportion of the intervention group was retained in care, but the difference was not statistically significant (53.1% vs 45.6%, aOR 1.27, 95% CI 0.93-1.73). There was no significant difference in adjusted odds of 6-month hospitalization or ED visit between groups., Conclusions: Low barrier MOUD engaged a higher risk population and did not result in any statistically significant difference in retention in care compared with a historical control. Future research should determine what interventions improve retention of patients engaged through low barrier care. Primary care clinics can implement low barrier treatment to make MOUD accessible to a broader population., (© 2022. The Author(s).)

Background: As opioid-related hospitalizations rise, hospitals must be prepared to evaluate and treat patients with opioid use disorder (OUD). We implemented a hospitalist-led program, Project Caring for patients with Opioid Misuse through Evidence-based Treatment (COMET) to address gaps in care for hospitalized patients with OUD., Objective: Implement evidence-based treatment for inpatients with OUD and refer to postdischarge care., Design, Setting, and Participants: Project COMET launched in July 2019 at Duke University Hospital (DUH), an academic medical center in Durham, NC., Intervention, Main Outcomes, and Measures: We engaged key stakeholders, performed a needs assessment, and secured health system funding. We developed protocols to standardize OUD treatment and employed a social worker to facilitate postdischarge care. Electronic health records were utilized for data analysis., Results: COMET evaluated 512 patients for OUD during their index hospitalization from July 1, 2019 through June 30, 2021. Seventy-one percent of patients received medication for OUD (MOUD) during admission. Of those who received buprenorphine during admission, 64% received a discharge prescription. Of those who received methadone during admission, 83% of eligible patients were connected to a methadone clinic. Among all patients at DUH with OUD, MOUD use during hospitalization and at discharge increased in the post-COMET period compared to the pre-COMET period (p < .001 for both)., Conclusion: Our program is one of the first to demonstrate successful implementation of a hospitalist-led, comprehensive approach to caring for hospitalized patients with OUD and can serve as an example to other institutions seeking to implement life-saving, evidence-based treatment in this population., (© 2022 The Authors.

There exists a geographic maldistribution of surgeons with significant regional characteristics, which is associated with surgical access differentials that may be contributing to existing health disparities in the United States. We sought to evaluate the trends in the surgical workforce in southern states of the United States from 1981 to 2006 using the American Medical Association Masterfile data. Our study revealed that the general surgery workforce growth peaked in 1986 and has had negative growth per capita as a result of the consistent population growth, unlike other regions in the country. Furthermore, the change in the geographic distribution of general surgeons in the South was slightly greater than for surgical specialists between 1981 and 2006. Twenty-nine per cent of all southern counties with a collective population of 7.4 million people had no general surgeon in 2006. The failure of the general surgery workforce to grow with population expansion has resulted in a significant number of counties that do not meet the recommended standards of geographic access to surgical care. An adequate solution to surgical workforce demand is imperative for viable and successful implementation of healthcare reform, particularly in geographic regions with large healthcare access disparities.

Background: The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 established funding to allow Medicare beneficiaries to enroll in plans providing outpatient prescription drug coverage beginning in January 2006. The Medicare Part D program has changed the means by which beneficiaries purchase prescription drugs, impacting the business operations of pharmacies., Objectives: To describe the experiences of rural independently owned pharmacies that are the sole retail pharmacy in their community 1 year after implementation of Medicare Part D, in order to learn if the initial financial and administrative problems associated with the implementation of the program in 2006 resolved over time., Methods: A semistructured interview protocol was used in telephone interviews with 51 pharmacist owners of rural sole community pharmacies in 27 states who were identified through a random sampling process., Results: The sole community pharmacists interviewed continue to face challenges directly related to Medicare Part D. Dealing with Part D plans and working with patients during enrollment periods remains administratively burdensome. Reimbursement amounts, complexity of dealing with multiple plans, and timeliness of payments continue to be cited as problems which could threaten the viability of independently owned pharmacies who are the sole retail providers in their communities., Conclusions: Actions should be considered to help sole community pharmacies deal with the ongoing administrative and financial challenges of Part D. To ensure full choice for rural Medicare beneficiaries and full access to pharmaceuticals through the ongoing presence of a local pharmacy, the development of a mechanism to structure prescription reimbursement so that drug acquisition costs and related overhead are covered and a reasonable profit margin provided should be considered. Further study is needed to determine how existing policies and regulations can be modified to ensure reasonable access to pharmacy services for rural Medicare and Medicaid beneficiaries.

Objective: To examine the effect of rural hospital closures on the local economy., Data Sources: U.S. Census Bureau, OSCAR, Medicare Cost Reports, and surveys of individuals knowledgeable about local hospital closures., Study Design: Economic data at the county level for 1990-2000 were combined with information on hospital closures. The study sample was restricted to rural counties experiencing a closure during the sample period. Longitudinal regression methods were used to estimate the effect of hospital closure on per-capita income, unemployment rate, and other community economic measures. Models included both leading and lagged closure terms allowing a preclosure economic downturn as well as time for the closure to be fully realized by the community., Data Collection: Information on closures was collected by contacting every state hospital association, reconciling information gathered with that contained in the American Hospital Association file and OIG reports., Principal Findings: Results indicate that the closure of the sole hospital in the community reduces per-capita income by 703 dollars (p<0.05) or 4 percent (p<0.05) and increases the unemployment rate by 1.6 percentage points (p<0.01). Closures in communities with alternative sources of hospital care had no long-term economic impact, although income decreased for 2 years following the closure., Conclusions: The local economic effects of a hospital closure should be considered when regulations that affect hospitals' financial well-being are designed or changed.

The authors profile facilities converting to critical access hospitals (CAHs) from 1998-2000, comparing characteristics of their communities, operations, and finances to those of other small rural providers. Counties where CAHs are located are more sparsely populated, but do not have substantially different sociodemographic profiles than other rural counties. Converting hospitals' acute daily census averaged well below the statutory limit of 15, but over one-half reduced unused bed capacity to meet CAH size limitations. The average case-mix adjusted Medicare cost per case was 16-percent higher for CAH converters than for other small hospitals and their financial ratios were substantially worse, although many other operating characteristics were similar.

This study updates a 1997 study examining implementation of rural Medicaid managed care programs. Most states operate Medicaid managed care programs for their beneficiaries, but the types of programs vary across urban and rural settings. Over the past four years the number of rural counties covered by Medicaid managed care, including fully capitated programs, has grown, although primary care case management (PCCM) remains the predominant program type in rural areas. Health plan withdrawals from rural areas have led some states with rural capitated programs to provide financial incentives or develop alternative approaches, such as enhanced PCCM programs.

Nearly one third of patients with heparin-induced thrombocytopenia (HIT) will progress to overt thrombosis. Owing to the severity of HIT, a reliable prompt diagnosis is mandatory. In this study 248 consecutive samples from patients referred to our laboratory for HIT diagnosis and 97 specimens from normal controls were prospectively evaluated in parallel using the heparin-induced platelet aggregation (HIPA) test and a flow cytometric (FC) test. The HIPA test resulted in 214 negative, 17 indeterminate and 17 positive samples of patients. The FC method detects activated platelets induced by heparin-immune complexes using the highly sensitive recombinant probe annexin V and pooled platelets from multiple donors. The criteria for positive FC test results included an increase in platelet activiation of at least 11% at 0.3 IU/mL heparin concentration in the tube, and a ratio of more than 1.5 between platelet activation at 0.3 and 200 IU/mL heparin. According to the cut-off level 17 patients who showed indeteminate HIPA test results had 14 negative and 3 indeterminate corresponding FC test results. Only one of these patients (HIPA test indeterminate, FC test indeterminate) had no other obvious medical cause for thrombocytopenia than HIT. Infections or inflammations did not show any association with the FC test results, whereas thromboembolic events displayed a significant patelet activation at pharmacological heparin concentration. Therefore the FC test is associated to the complications of HIT. In conclusion, the FC test, which is fast and practical, showed a good agreement with the HIPA test and may be an accurate and useful test for HIT.

Serum neural cell adhesion molecule (NCAM), a possible prognostic marker for multiple myeloma (MM), was determined by means of an enzyme immunoassay, which showed good linearity and high precision. In 95% of healthy controls (n = 70), NCAM values were below 18.7 U/mL. In patients with monoclorlal gammopathies of undetermined significance (MGUS) (n = 31) or polyclonal gammopathies (n = 53) the cut off was 23.1 U/mL. MM in active stage (n = 52) showed significantly higher NCAM levels (p < 0.001) than in asymptomatic stage (n = 44). In active myeloma the sensitivity of serum markers were found to be: NCAM 40%, beta 2-microglobulin beta 2-M) 52% and serum thymidine-kinase (S-TK) 41% (cut off defined on MGUS). The combined sensitivities ranged between 55 and 60% (NCAM+ beta 2-M, beta 2-M+S-TK, NCAM+S-TK). No correlation with beta 2-M or S-TK could be demonstrated. However, NCAM values were correlated with the concentration of monoclonal immunoglobulin (IgG-paraprotein: r = 0.45; IgA-paraprotein: r = 0.58). In the follow-up of patients with myeloma, NCAM values decreased in response to chemotherapy and were low in smouldering myeloma. But in three patients with progression NCAM did not reflect the tumor activity. At the time of censor, 80% of patients (n = 80) with a pre-treatment NCAM of < 18.5 U/mL and 61% of patients with a NCAM of > 18.5 U/mL were still alive. NCAM showed a low prognostic significance (log-rank: p < 0.07). Seven of ten myeloma patients with CD56 expression on plasma cell surface, which was examined by flow cytometry, displayed a high concentration of NCAM in serum. All other non-Hodgkin's lymphomas (21 immunocytoma, 27 chronic lymphocytic leukemia, 16 centrocytic/centroblastic-centrocytic lymphoma, 24 high-grade lymphoma) had low NCAM concentrations in serum and did not significantly vary in follow-up. In conclusion, serum NCAM could be a marker for the staging and monitoring of MM. However, it seems, that NCAM did not provide additional prognostic information relating to beta 2-M, S-TK or paraprotein.

S-TK (Serum thymidine kinase) levels were determined by means of a radioenzyme assay (REA). In 95% of healthy controls (n = 97), S-TK values were below 8.5 U/L. In patients with monoclonal gammopathies of undetermined significance (MGUS) (n = 27) or polyclonal gammopathies (n = 45) the cut off was 10.3 U/L respectively 25 U/L. Patients with viral disease (n = 16), especially infections with Epstein-Barr virus, Hepatitis-virus and HIV, had elevated S-TK values of up to 215 U/L. In 95 patients with multiple myeloma (MM) and 103 patients with other various non-Hodgkin lymphomas (NHL) S-TK levels were investigated. With regard to monoclonal gammopathies, MGUS had lower S-TK than MM patients (p < 0.05) and patients with stage I MM according to Durie and Salmon had S-TK levels significantly lower than those with more advanced stages (p < 0.01). There was a correlation between S-TK and plasma cell labeling index (r = 0.56, p < 0.001). Patients with chronic lymphocytic leukemia showed significantly higher S-TK levels in the RAI stages 3 and 4 than in stages 1 and 2 (p < 0.01). In cases of other malignant NHL in progression sensitivities of S-TK were found to be: immunocytoma 36%, centrocytic/centroblastic-centrocytic lymphoma 54% and high-grade NHL 40% (cut off defined on lymphomas in remission). S-TK levels varied in MM according to the course of disease and response to therapy decreasing at remission and increasing again at relapse. Analogous variations were found in the other NHL. After two years, 83% of patients with a pretreatment S-TK of < 10 U/L and 47% of the patients with a S-TK of > or = 10 U/L were still alive. S-TK proved to be a highly significant prognostic indicator for MM patients (log-rank and Wilcoxon: p < 0.0001). In the other NHL patients with a S-TK level greater than 10 U/L had a median follow-up of only 7 months. NHL patients with lower S-TK levels did not yet reach the median survival time (log-rank and Wilcoxon. p < 0.005). Our results suggest that the determination of S-TK may help to monitor the clinical course of NHL during therapy and predict the prognosis of NHL.

Veno-occlusive disease (VOD) of the liver is one of the most frequent fatal complications after bone marrow transplantation (BMT). A decrease of natural anticoagulants, in particular protein C (PC), has been assumed to be involved in the pathogenesis of the disease. We determined PC and antithrombin III (AT III) levels in two patients undergoing BMT and subsequent liver transplantation due to VOD. Additionally, in one of the patients protein S (PS) levels were also measured. Normal baseline (day-8) PC levels (86 and 89%) were markedly reduced in both patients at the time of VOD manifestation on day 20 and 40, respectively (26 and 31%). PS levels lay within the normal range from day-8 (before myeloablative chemotherapy) until one week after clinical onset of VOD when substitution therapy with fresh frozen plasma (FFP) was initiated. AT III levels decreased moderately during the second and third posttransplant week, but were normal in the patient with a late clinical manifestation of VOD. In both patients PC and PS levels lay within the normal range after liver transplantation which was performed on day 41 and 79, respectively. AT III was substituted several times. Both patients died due to infectious complications on day 141 and 101, respectively. The data confirm previous reports that a decrease of PC is observed in BMT recipients and can be associated with hepatic vein occlusion. Whereas the relevance of AT III is uncertain, PS does not seem to be involved in the pathogenesis of VOD. Liver transplantation lead to normalization of PC levels, but its significance remains to be discussed in terms of ethical justifiability, medical feasibility and costs.

Recently CYFRA 21-1, a new tumour marker measuring a fragment of cytokeratin 19, was introduced and proved to be suitable for the follow-up care and monitoring of the therapy of non-small cell lung carcinomas, especially squamous cell carcinomas of the lung. Besides CYFRA 21-1, there are two other tumour markers available, called tissue polypeptide antigen (TPA) and tissue polypeptide specific antigen (TPS), which also measure different cytokeratins in serum. In a retrospective study we investigated the clinical significance of these 3 cytokeratin markers in lung cancer compared with carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCC) and neuron-specific enolase (NSE). We investigated the sera of 50 healthy persons, 273 patients with various benign diseases and 218 patients with histologically proven lung cancer. In a first step the specificity versus benign diseases of the lung was established for all the markers, and was fixed at 95%. Then the single and combined sensitivities were calculated. CYFRA 21-1 proved to possess the highest sensitivity in lung cancer in general (61%), in non-small cell lung carcinomas (64%), in squamous cell carcinomas (79%), in adenocarcinomas (54%) and in large cell carcinomas (65%). In small cell lung carcinomas, neuron-specific enolase proved again to be the marker of first choice (55%). Combined determinations proved clearly increased sensitivity only for large cell carcinomas (CYFRA 21-1 + TPA: 77%) and for small cell lung carcinomas (CYFRA 21-1 + NSE: 62%).(ABSTRACT TRUNCATED AT 250 WORDS)
