Decomposing the gaps in healthy and unhealthy life expectancies between Indigenous and non-Indigenous Australians: a burden of disease and injury study.

BACKGROUND: The gaps in healthy life expectancy (HLE) between Indigenous and non-Indigenous Australians are significant. Detailed and accurate information is required to develop strategies that will close these health disparities. This paper aims to quantify and compare the causes and their relative contributions to the life expectancy (LE) gaps between the Indigenous and non-Indigenous population in the Northern Territory (NT), Australia. METHODS: The age-cause decomposition was used to analyse the differences in HLE and unhealthy life expectancy (ULE), where LE = HLE + ULE. The data was sourced from the burden of disease and injury study in the NT between 2014 and 2018. RESULTS: In 2014-2018, the HLE at birth in the NT Indigenous population was estimated at 43.3 years in males and 41.4 years in females, 26.5 and 33.5 years shorter than the non-Indigenous population. This gap approximately doubled the LE gap (14.0 years in males, 16.6 years in females) at birth. In contrast to LE and HLE, ULE at birth was longer in the Indigenous than non-Indigenous population. The leading causes of the ULE gap at birth were endocrine conditions (explaining 2.9-4.4 years, 23-26%), followed by mental conditions in males and musculoskeletal conditions in females (1.92 and 1.94 years, 15% and 12% respectively), markedly different from the causes of the LE gap (cardiovascular disease, cancers and unintentional injury). CONCLUSIONS: The ULE estimates offer valuable insights into the patterns of morbidity particularly useful in terms of primary and secondary prevention.

Medication patterns and dosing guidance in pediatric patients supported with intermittent hemodialysis or continuous kidney replacement therapy.

BACKGROUND: Hemodialysis is a life-saving technology used during periods of acute or chronic kidney failure to remove toxins, and maintain fluid, electrolyte and metabolic balance. While this technology plays an important role for pediatric patients with kidney dysfunction, it can alter the pharmacokinetic behavior of medications placing patients at risk for suboptimal dosing and drug toxicity. The ability to directly translate pharmacokinetic alterations into dosing recommendations has thus far been limited and dosing guidance specific to pediatric hemodialysis patients is rare. Despite differences in dialysis prescription and patient populations, intermittent (iHD) and continuous kidney replacement therapy (CKRT) patients are often pooled together. In order to develop evidence-based dosing guidelines, it is important to first prioritize drugs for study in each modality. METHODS: Here we aim to identify priority drugs in two hemodialysis modalities, through: 1) Identification of hospitalized, pediatric patients who received CKRT or intermittent hemodialysis (iHD) using a machine learning-based predictive model based on medications; 2) Identification of medication administration patterns in these patient cohorts; and 3) Identification of the most commonly prescribed drugs that lack published dosing guidance. RESULTS: Notable differences were found in the pattern of medications and drug dosing guidance between iHD and CKRT patients. Antibiotics, diuretics and sedatives were more common in CKRT patients. Out of the 50 most commonly administered medications in the two modalities, only 34% and 28% had dosing guidance present for iHD and CKRT, respectively. CONCLUSIONS: Our results add to the understanding of the differences between iHD and CKRT patient populations by identifying commonly used medications that lack dosing guidance for each hemodialysis modality, helping to pinpoint priority medications for further study. Overall, this study provides an overview of the current limitations in medication use in this at-risk population, and provides a framework for future studies by identifying commonly used medications in pediatric CKRT and iHD patients.

The efficiency, timeliness, health outcomes and cost-effectiveness of a new aeromedical retrieval model in Central Australia: A pre- and post-implementation observational study.

OBJECTIVE: To assess timeliness, efficiency, health outcomes and cost-effectiveness of the 2018 redesigned Central Australian aeromedical retrieval model. DESIGN: Pre- and postimplementation observational study of all patients receiving telehealth consultations from remote medical practitioners (RMPs) or Medical Retrieval and Consultation Centre (MRaCC) physicians between 1/1/2015 and 29/2/2020. Descriptive and inferential statistics measuring system efficiency, timeliness, health outcomes and incremental cost-effectiveness. FINDINGS: There were 9%-10% reductions in rates of total aeromedical retrievals, emergency department admissions and hospitalisations postimplementation, all p-values < 0.001. Usage rates for total hospital bed days and ICU hours were 17% lower (both p < 0.001). After adjusting for periodicity (12% fewer retrievals on weekends), each postimplementation year, there were 0.7 fewer retrievals/day (p = 0.002). The mean time from initial consultation to aeromedical departure declined by 18 minutes post-implementation (115 vs. 97 min, p = 0.007). The hazard of death within 365 days was nonsignificant (0.912, 95% CI 0.743-1.120). Postimplementation, it cost $302 more per hospital admission and $3051 more per year of life saved, with a 75% probability of cost-effectiveness. These costs excluded estimated savings of $744,528/year in reduced hospitalisations and the substantial social and out-of-pocket costs to patients and their families associated with temporary relocation to Alice Springs. CONCLUSION: Central Australia's new critical care consultant-led aeromedical retrieval model is more efficient, is dispatched faster and is more cost-effective. These findings are highly relevant to other remote regions in Australia and internationally that have comparable GP-led retrieval services.

Interaction of ceftazidime and clindamycin with extracorporeal life support.

BACKGROUND: Ceftazidime and clindamycin are commonly prescribed to critically ill patients who require extracorporeal life support such as ECMO and CRRT. The effect of ECMO and CRRT on the disposition of ceftazidime and clindamycin is currently unknown. METHODS: Ceftazidime and clindamycin extraction were studied with ex vivo ECMO and CRRT circuits primed with human blood. The percent recovery of these drugs over time was calculated to determine the degree of interaction between these drugs and circuit components. RESULTS: Neither ceftazidime nor clindamycin exhibited measurable interactions with the ECMO circuit. In contrast, CRRT cleared 100% of ceftazidime from the experimental circuit within the first 2 h. Clearance of clindamycin from the CRRT circuit was slower, with about 20% removed after 6 h. CONCLUSION: Clindamycin and ceftazidime dosing adjustments are likely required in patients who are supported with CRRT, and future studies to quantify these adjustments should consider the pathophysiology of the patient in combination with the clearance due to CRRT. Dosing adjustments to account for adsorption to ECMO circuit components are likely unnecessary and should focus instead on the pathophysiology of the patient and changes in volume of distribution. These results will help improve the safety and efficacy of ceftazidime and clindamycin in patients requiring ECMO and CRRT.

Meropenem extraction by ex vivo extracorporeal life support circuits.

BACKGROUND: Meropenem is a broad-spectrum carbapenem-type antibiotic commonly used to treat critically ill patients infected with extended-spectrum ß-lactamase (ESBL)-producing Enterobacteriaceae. As many of these patients require extracorporeal membrane oxygenation (ECMO) and/or continuous renal replacement therapy (CRRT), it is important to understand how these extracorporeal life support circuits impact meropenem pharmacokinetics. Based on the physicochemical properties of meropenem, it is expected that ECMO circuits will minimally extract meropenem, while CRRT circuits will rapidly clear meropenem. The present study seeks to determine the extraction of meropenem from ex vivo ECMO and CRRT circuits and elucidate the contribution of different ECMO circuit components to extraction. METHODS: Standard doses of meropenem were administered to three different configurations (n = 3 per configuration) of blood-primed ex vivo ECMO circuits and serial sampling was conducted over 24 h. Similarly, standard doses of meropenem were administered to CRRT circuits (n = 4) and serial sampling was conducted over 4 h. Meropenem was administered to separate tubes primed with circuit blood to serve as controls to account for drug degradation. Meropenem concentrations were quantified, and percent recovery was calculated for each sample. RESULTS: Meropenem was cleared at a similar rate in ECMO circuits of different configurations (n = 3) and controls (n = 6), with mean (standard deviation) recovery at 24 h of 15.6% (12.9) in Complete circuits, 37.9% (8.3) in Oxygenator circuits, 47.1% (8.2) in Pump circuits, and 20.6% (20.6) in controls. In CRRT circuits (n = 4) meropenem was cleared rapidly compared with controls (n = 6) with a mean recovery at 2 h of 2.36% (1.44) in circuits and 93.0% (7.1) in controls. CONCLUSION: Meropenem is rapidly cleared by hemodiafiltration during CRRT. There is minimal adsorption of meropenem to ECMO circuit components; however, meropenem undergoes significant degradation and/or plasma metabolism at physiological conditions. These ex vivo findings will advise pharmacists and physicians on the appropriate dosing of meropenem.

Evaluation of a new medical retrieval and primary health care advice model in Central Australia: Results of pre- and post-implementation surveys.

INTRODUCTION: In February 2018 the Remote Medical Practitioner (RMP)-led telehealth model for providing both primary care advice and aeromedical retrievals in Central Australia was replaced by the Medical Retrieval and Consultation Centre (MRaCC) and Remote Outreach Consultation Centre (ROCC). In this new model, specialists with advanced critical care skills provide telehealth consultations for emergencies 24/7 and afterhours primary care advice (MRaCC) while RMPs (general practitioners) provide primary care telehealth advice in business hours via the separate ROCC. OBJECTIVE: To evaluate changes in clinicians' perceptions of efficiency and timeliness of the new (MRaCC) and (ROCC) model in Central Australia. DESIGN: There were 103 and 72 respondents, respectively, to pre- and post-implementation surveys of remote clinicians and specialist staff. FINDINGS: Both emergency and primary care aspects of telehealth support were perceived as being significantly more timely and efficient under the newly introduced MRaCC/ROCC model. Importantly, health professionals in remote community were more likely to feel that their access to clinical support during emergencies was consistent and immediately available. DISCUSSION: Respondents consistently perceived the new MRaCC/ROCC model more favourably than the previous RMP-led model, suggesting that there are benefits to having separate referral streams for telehealth advice for primary health care and emergencies, and staffing the emergency stream with specialists with advanced critical care skills. CONCLUSION: Given the paucity of literature about optimal models for providing pre-hospital medical care to remote residents, the findings have substantial local, national and international relevance and implications, particularly in similar geographically large countries, with low population density.

Comparison of 4-factor PCC reversal of apixaban and rivaroxaban versus warfarin for intracranial hemorrhage.

The purpose of this study is to assess efficacy of 4-factor prothrombin complex concentrates (4F-PCC) for direct oral anticoagulant (DOAC)-associated intracranial hemorrhage (ICH) as compared to its use in warfarin-associated ICH. A retrospective cohort study was performed to compare the efficacy of 4F-PCC for reversal of apixaban and rivaroxaban versus warfarin for ICH at Cooper University Health Care from January 2015 to December 2019. Patients included were ≥ 18 years of age who developed an ICH while on apixaban, rivaroxaban, or warfarin. The primary outcome was to compare the percentage of patients with Excellent or Good hemostatic efficacy after 4F-PCC administration. Secondary outcomes were to describe functional outcomes at discharge, in-hospital mortality, and thrombotic complications after 4F-PCC administration. A total of 159 patients were included; 115 patients received warfarin and 44 patients received a DOAC (apixaban, n = 22; rivaroxaban, n = 22). 70 patients were evaluable for the primary endpoint. Thirty-four (66.7%) patients in the warfarin group versus 14 (73.7%) patients in the DOAC group were determined to have excellent or good hemostatic efficacy (p = 0.57). In-hospital mortality (30.4% vs. 40.9%, p = 0.21) and thrombotic complications (9.6% vs. 11.4%, p = 0.67) were comparable between the warfarin vs. DOAC groups, respectively. This small, retrospective study found no difference in patients with excellent/good hemostatic efficacy after reversal with 4F-PCC for DOAC-associated ICH compared to warfarin-associated ICH. This study is limited by its retrospective nature and sample size. Larger, prospective studies are needed to further determine the efficacy of 4F-PCC in reversing DOAC-associated ICH.

Cefepime Extraction by Extracorporeal Life Support Circuits.

Extracorporeal life support (ECLS) devices are lifesaving for critically ill patients with multi-organ dysfunction. Despite this, patients supported with ECLS are at high risk for ECLS-related complications, including nosocomial infections, and mortality rates are high in this patient population. The high mortality rates are suspected to be, in part, a result of significantly altered drug disposition by the ECLS circuit, resulting in suboptimal antimicrobial dosing. Cefepime is commonly used in critically ill patients with serious infections. Cefepime dosing is not routinely guided by therapeutic drug monitoring and treatment success is dependent upon the percentage of time of the dosing interval that the drug concentration remains above the minimum inhibitory concentration of the organism. This ex vivo study measured the extraction of cefepime by continuous renal replacement therapy (CRRT) and extracorporeal membrane oxygenation (ECMO) circuits. Cefepime was studied in four closed-loop CRRT circuit configurations and a single closed-loop ECMO circuit configuration. Circuits were primed with a physiologic human blood-plasma mixture and the drug was dosed to achieve therapeutic concentrations. Serial blood samples were collected over time and concentrations were quantified using validated assays. In ex vivo CRRT experiments, cefepime was rapidly cleared by dialysis, hemofiltration, and hemodiafiltration, with greater than 96% cefepime eliminated from the circuit by 2 hours. In the ECMO circuits, the mean recovery of cefepime was similar in both circuit and standard control. Mean (standard deviation) recovery of cefepime in the ECMO circuits (n = 6) was 39.2% (8.0) at 24 hours. Mean recovery in the standard control (n = 3) at 24 hours was 52.2% (1.5). Cefepime is rapidly cleared by dialysis, hemofiltration, and hemodiafiltration in the CRRT circuit but minimally adsorbed by either the CRRT or ECMO circuits. Dosing adjustments are needed for patients supported with CRRT.

Prevalence of specialised palliative care consultation for eligible children within a paediatric cardiac ICU.

OBJECTIVE: Retrospectively apply criteria from Center to Advance Palliative Care to a cohort of children treated in a cardiac ICU and compare children who received a palliative care consultation to those who were eligible for but did not receive one. METHODS: Medical records of children admitted to a cardiac ICU between January 2014 and June 2017 were reviewed. Selected criteria include cardiac ICU length of stay >14 days and/or ≥ 3 hospitalisations within a 6-month period. MEASUREMENTS AND RESULTS: A consultation occurred in 17% (n = 48) of 288 eligible children. Children who received a consult had longer cardiac ICU (27 days versus 17 days; p < 0.001) and hospital (91 days versus 35 days; p < 0.001) lengths of stay, more complex chronic conditions at the end of first hospitalisation (3 versus1; p < 0.001) and the end of the study (4 vs.2; p < 0.001), and higher mortality (42% versus 7%; p < 0.001) when compared with the non-consulted group. Of the 142 pre-natally diagnosed children, only one received a pre-natal consult and 23 received it post-natally. Children who received a consultation (n = 48) were almost 2 months of age at the time of the consult. CONCLUSIONS: Less than a quarter of eligible children received a consultation. The consultation usually occurred in the context of medical complexity, high risk of mortality, and at an older age, suggesting potential opportunities for more and earlier paediatric palliative care involvement in the cardiac ICU. Screening criteria to identify patients for a consultation may increase the use of palliative care services in the cardiac ICU.

Palliative Care in Children With Heart Disease Treated in an ICU.

OBJECTIVES: Describe pediatric palliative care consult in children with heart disease; retrospectively apply Center to Advance Palliative Care criteria for pediatric palliative care consults; determine the impact of pediatric palliative care on end of life. DESIGN: A retrospective single-center study. SETTING: A 16-bed cardiac ICU in a university-affiliated tertiary care children's hospital. PATIENTS: Children (0-21 yr old) with heart disease admitted to the cardiac ICU from January 2014 to June 2017. MEASUREMENTS AND MAIN RESULTS: Over 1,000 patients (n = 1, 389) were admitted to the cardiac ICU with 112 (8%) receiving a pediatric palliative care consultation. Patients who received a consult were different from those who did not. Patients who received pediatric palliative care were younger at first hospital admission (median 63 vs 239 d; p = 0.003), had a higher median number of complex chronic conditions at the end of first hospitalization (3 vs 1; p < 0.001), longer cumulative length of stay in the cardiac ICU (11 vs 2 d; p < 0.001) and hospital (60 vs 7 d; p < 0.001), and higher mortality rates (38% vs 3%; p < 0.001). When comparing location and modes of death, patients who received pediatric palliative care were more likely to die at home (24% vs 2%; p = 0.02) and had more comfort care at the end of life (36% vs 2%; p = 0.002) compared to those who did not. The Center to Advance Palliative Care guidelines identified 158 patients who were eligible for pediatric palliative care consultation; however, only 30 patients (19%) in our sample received a consult. CONCLUSIONS: Pediatric palliative care consult rarely occurred in the cardiac ICU. Patients who received a consult were medically complex and experienced high mortality. Comfort care at the end of life and death at home was more common when pediatric palliative care was consulted. Missed referrals were apparent when Center to Advance Palliative Care criteria were retrospectively applied.

Effect of the experience of surgical chairpersons on departmental National Institutes of Health funding.

BACKGROUND: Experience and application of recruitment packages can be critical in leadership efforts of surgical chairpersons in promoting research, although attrition of these efforts can happen over time due to lack of new resources. We aimed to examine the impact of experience of surgical chairpersons on departmental National Institutes of Health (NIH) funding. METHODS: Experience as a chairperson defined as the number of years spent as an interim or permanent chair was abstracted from the department Web site (US medical schools only). The NIH funding (US dollars) of the departments were obtained from the Blue Ridge Medical Institute (www.brimr.org). The change in NIH funding from the immediate previous financial year (2010-2009 and 2011-2010) was used to classify chairpersons into four groups: group 1 (-/-), group 2 (-/+), group 3 (+/+), and group 4 (+/-) for analysis. RESULTS: Median NIH funding were $1.9 (0.7-6) million, $1.8 (0.6-5) million, and $1.7 (0.7-5) million for 2009, 2010, and 2011, respectively, and the median experience as a surgical chairperson was 6 y (3-10). Recent chairpersons (<1 y) inherited departments that usually lost NIH funding (62%) and were frequently unable to develop a positive trend for growth over the next fiscal year ([-/-] n = 4 and [+/-] n = 2, 75%). Chairpersons who held their positions for 4-6 y were most likely to be associated with trends of positive funding growth, whereas chairpersons >10 y were most likely to have lost funding (66%, P = 0.07). CONCLUSIONS: Provision of new development dollars later in their tenure and retention of chairpersons might lead to more positive trends in increase in NIH funding.

Back pain as the initial presentation of subacute bacterial endocarditis in a patient with a complex medical history.

Infective endocarditis (IE) poses a diagnostic challenge due to its diverse clinical presentations, especially among high-risk groups. Diagnosis relies on integrating clinical presentation, blood cultures and imaging findings. Advanced imaging techniques enhance diagnostic accuracy, particularly in complex cases. Treatment involves antimicrobial therapy and surgery in complicated cases, with early intervention crucial for optimal outcomes. Coordinated care by an Endocarditis Team ensures tailored treatment plans, prompt complication management and long-term monitoring after discharge. The authors present a case of subacute IE presenting initially with back pain in a patient with a complex medical history, highlighting diagnostic and management approaches.

Bone structure and B-cell populations, crippled by obesity, are partially rescued by brief daily exposure to low-magnitude mechanical signals.

Deterioration of the immune and skeletal systems, each of which parallel obesity, reflects a fragile interrelationship between adiposity and osteoimmunology. Using a murine model of diet-induced obesity, this study investigated the ability of mechanical signals to protect the skeletal-immune systems at the tissue, cellular, and molecular level. A long-term (7 mo) high-fat diet increased total adiposity (+62%), accelerated age-related loss of trabecular bone (-61%), and markedly reduced B-cell number in the marrow (-52%) and blood (-36%) compared to mice fed a regular diet. In the final 4 mo of the protocol, the application of low-magnitude mechanical signals (0.2 g at 90 Hz, 15 min/d, 5 d/wk) restored both bone structure and B cells to those levels measured in control mice fed a regular diet. These phenotypic outcomes were achieved, in part, by reductions in osteoclastic activity and a biasing of hematopoietic stem cell differentiation toward the lymphoid B-cell lineage and away from a myeloid fate. These results emphasize that obesity undermines both the skeletal and immune systems, yet brief exposure to mechanical signals, perhaps as a surrogate to the salutary influence of exercise, diminishes the consequences of diabetes and obesity, restoring bone structure and normalizing B-cell populations by biasing of the fate of stem cells through mechanosensitive pathways.

Attributes of a surgical chairperson associated with extramural funding of a department of surgery.

BACKGROUND: Chairpersons of surgery departments are key stakeholders and role models and leaders of research in academic medical institutions. However, the characteristics of surgical chairpersons are understudied. This study aimed to investigate the association between the personal academic achievement of a surgical chairperson and the National Institutes of Health (NIH) funding of the department. METHODS: We calculated the Hirsch index (H-index), a measure of research productivity, for chairpersons of surgery of the top 90 research medical schools that were ranked by U.S. News & World Report. Specialty training, y as chairperson, location, and NIH institutional and department funding were analyzed. Nonparametric tests and linear regression methods were used to compare the different groups. RESULTS: Of the 90 chairpersons, 20 positions for chairs (22%) are either recent (<1 y) or unfilled (n = 6). Only 3% of all chairpersons are women, and the median H-index for the chairpersons is 20 (Interquartile range 14-27) with a median 101 publications with 14 cites per publication. Median surgery-specific NIH funding in 2011 was $1.7 million (Interquartile range $721,042-5,085,305). The chairperson's H-index was exponentially associated with department funding in multivariate models adjusting for institution rank, except when the H-index was extreme (<4 or >49) (coefficient 0.32, P = 0.02). CONCLUSIONS: The research productivity of a chairperson is the only personal attribute of those studied that is associated with the departmental NIH funding. This suggests the important role an academically productive surgical leader may play as a champion for the academic success of the department.

Timing of Pediatric Palliative Care Consults in Hospitalized Patients with Heart Disease.

Pediatric palliative care (PPC) provides an extra layer of support for families caring for a child with complex heart disease as these patients often experience lifelong morbidities with frequent hospitalizations and risk of early mortality. PPC referral at the time of heart disease diagnosis provides early involvement in the disease trajectory, allowing PPC teams to longitudinally support patients and families with symptom management, complex medical decision-making, and advanced care planning. We analyzed 113 hospitalized pediatric patients with a primary diagnosis of heart disease and a PPC consult to identify timing of first PPC consultation in relation to diagnosis, complex chronic conditions (CCC), and death. The median age of heart disease diagnosis was 0 days with a median of two CCCs while PPC consultation did not occur until a median age of 77 days with a median of four CCCs. Median time between PPC consult and death was 33 days (interquartile range: 7-128). Death often occurred in the intensive care unit ( n = 36, 67%), and the most common mode was withdrawal of life-sustaining therapies ( n = 31, 57%). PPC referral often occurred in the context of medical complexity and prolonged hospitalization. Referral close to the time of heart disease diagnosis would allow patients and families to fully utilize PPC benefits that exist outside of end-of-life care and may influence the mode and location of death. PPC consultation should be considered at the time of heart disease diagnosis, especially in neonates and infants with CCCs.

Does aerobic and strength exercise sequence in the same session affect the oxygen uptake during and postexercise?

Concurrent training is a strategy employed in both general fitness and sports conditioning. The purpose of this study was to compare the responses of VO2 in different combinations of strength exercise with aerobic interval exercise. Eight men (23.6 ± 4.2 years, 178 ± 6.3 cm, 77 ± 7.9 kg, 7.67 ± 1.95% body fat) completed 3 combinations of strength training (ST) and aerobic training (AT) in a randomized order with a 7-day recovery period: AT before ST exercises, AT between 2 blocks of ST exercises, and AT after ST exercises. The ST comprised 4 exercises performed in 3 sets of 10 reps and 2 exercises, abdominal crunch and lumbar extension, performed in 3 sets of 30 and 20 reps, respectively. The AT consisted of a 20-minute interval cycling. There were no significant differences in the values of absolute or relative VO2, in the heart rate (HR) and in the respiratory exchange ratio (RER) when the 3 sessions (during + postexercise measurements) were compared (values are mean ± SD). Analyzing only ST in each session, differences were detected in the RER values (F = 4.714; p < 0.05; η2 = 0.308) between AT before ST and AT in the middle of ST (1.01 ± 0.97 vs. 1.11 ± 0.07, respectively). In all sequences, there was a significant increase (p < 0.05) in the values of relative and absolute VO2 and HR, and a significant decrease in RER values (p < 0.05) from the first to the second part of the ST session. The values of absolute or relative VO2, HR, and RER did not vary significantly among the 3 sessions as compared with the AT after ST. These data support the hypothesis that ST and AT, when performed in sequence in the same session, do not seem to affect the overall oxygen consumption during the exercise session. Therefore, training sessions may incorporate both modalities without apparent impact on aerobic exercise.

A brief study on the effects of storage conditions on sexual lubricant components in the presence of a biological fluid.

This study illustrated the effects of environmental conditions (i.e., temperature) on the components of a condom lubricant in the presence of vaginal secretion. Understanding the effects of storage is important for the short-term handling of sexual assault kits, that may contain post-coital swabs, prior to chemical analysis. This preliminary three-day investigation utilized gas chromatography-mass spectrometry (GC-MS) to analyze the samples at three timepoints (24, 48, and 72 h). Lubricated and non-lubricated swabs were exposed to five storage conditions. After percent recovery calculation, GC-MS interpretation, and statistical analysis, it was determined that storing swabs at room temperature (22 °C) for up to 72 h best maintained the integrity of the sexual lubricant - in comparison to T0 - as opposed to colder storage temperatures of 4 °C and - 20 °C. Despite the varying degree of changes in the storage conditions and temperatures, PDMS components were persistent in all lubricated samples and can be used to confirm the presence of condom lubricant if initially present in the sample.

Insurance barriers to substance use disorder treatment after passage of mental health and addiction parity laws and the affordable care act: A qualitative analysis.

Introduction: People who use drugs (PWUDs) in the United States historically have had a higher probability of being uninsured. Passage of the Affordable Care Act, the Paul Wellstone and Pete Domenici Health Parity and Addiction Equity was expected to increase access to treatment for substance use disorder. Few studies to date have conducted qualitative research with substance use disorder (SUD) treatment providers regarding Medicaid and other insurance coverage of SUD treatment following passage of the ACA and parity laws. The present paper fills this gap by reporting data from in-depth interviews with treatment providers from three states, Connecticut, Kentucky, and Wisconsin, that differ in implementation of the ACA. Methods: Study teams in each state conducted in-depth, semi-structured interviews with key informants who provided SUD treatment, including providers of behavioral health residential or outpatient programs, office-based buprenorphine providers and opioid treatment programs [OTP, i.e. methadone clinics] (n = 24 in Connecticut, n = 63 in Kentucky and n = 63 in Wisconsin). Key informants were asked for their perceptions on how Medicaid and private insurance facilitates or limits access to drug treatment. All interviews were transcribed verbatim and analyzed for key themes using MAXQDA software using a collaborative approach. Results: Results from this study suggest that the promise of the ACA and parity laws to increase access to SUD treatment has only partially been realized. There is wide variation among the three states' Medicaid programs and among private insurance in the types of SUD treatment that is covered. Neither Kentucky's nor Connecticut's Medicaid covered methadone. Wisconsin Medicaid did not cover residential or intensive outpatient treatment. Thus, none of the states studied here provided all levels of care that the ASAM recommends for treating SUD. Further, there were several quantitative limits placed on SUD treatment such as number of urine drug screens or visits allowed. Providers complained that many treatments required prior authorizations, including MOUD like buprenorphine. Conclusions: More reform is needed to make SUD treatment accessible to all who need it. Such reforms should consider defining standards for opioid use disorder treatment with reference to evidence-based practices, not be attempting parity with an arbitrarily defined medical standard.
