RESUMEN

Background: Cochlear implants and hearing aids may facilitate the development of listening and spoken language (LSL) in deaf/hard of hearing young children, but they require aural rehabilitation therapy-often unavailable outside urban areas-for optimal outcomes. This trial assessed the relative effectiveness of LSL therapy delivered either in person or by interactive video. The hypothesis was that telehealth service delivery would be noninferior to in-person therapy. Methods: Most parents refused randomization of their children to telehealth or in-person conditions; therefore, randomization was impossible. In consultation with the funder (NIDCD), the study design was modified. Parents were allowed to select their preferred study condition, and the study team was blinded to group membership. Forty-two families were in the in-person group and 35 in telehealth (40 and 30, respectively, after attrition). Primary endpoints were total score, auditory comprehension, and expressive communication on the Preschool Language Scale, 5th edition. There were several secondary speech, hearing, and language outcome measures. Assessments occurred at baseline and at follow-up after 6 months of LSL therapy. Results: Propensity scores were used to create two matched groups. At baseline, groups did not differ on PLS-5 scores. Change from baseline to F/U on age-equivalents for all three scores was nearly identical for both groups, although the telehealth group was younger, on average, than the in-person group. Discussion: Telehealth was noninferior to in-person services for all primary endpoints. For secondary outcomes, neither group demonstrated a significant advantage. Magnitudes of estimated group differences were small, suggesting nonsignificant differences not predominantly because of sample size. The telehealth group showed greater improvement on 15/24 of secondary language outcome measures. The findings provide evidence that telehealth is equivalent to in-person care for providing LSL therapy to young children with cochlear implants and hearing aids.

RESUMEN

Currently, silicon-strain-gauge-based diaphragm pressure sensors use four single-gauge chips for high-output sensitivity. However, the four-single-gauge configuration increases the number of glass frit bonds and the number of aluminum wire bonds, reducing the long-term stability, reliability, and yield of the diaphragm pressure sensor. In this study, a new design of general-purpose silicon strain gauges was developed to improve the sensor output voltage while reducing the number of bonds. The new gauges consist grid patterns with a reciprocating arc of silicon piezoresistors on a thin glass backing. The gauges make handling easier in the bonding process due to the use of thin glass for the gauge backing. The pressure sensors were tested under pressure ranging from 0 to 50 bar at five different temperatures, with a linear output with a typical sensitivity of approximately 16 mV/V/bar and an offset shift of -6 mV to 2 mV. The new approach also opens the possibility to extend arc strain gauges to half-bridge and full-bridge configurations to further reduce the number of glass frit and Al wire bonds in the diaphragm pressure sensor.

RESUMEN

Half-bridge silicon strain gauges are widely used in the fabrication of diaphragm-type high-pressure sensors, but in some applications, they suffer from low output sensitivity because of mounting position constraints. Through a special design and fabrication approach, a new half-bridge silicon strain gauge comprising one arc gauge responding to tangential strain and another linear gauge measuring radial strain was developed using Silicon-on-Glass (SiOG) substrate technology. The tangential gauge consists of grid patterns, such as the reciprocating arc of silicon piezoresistors on a thin glass substrate. When two half-bridges are connected to form a full bridge with arc-shaped gauges that respond to tangential strain, they have the advantage of providing much higher output sensitivity than a conventional half-bridge. Pressure sensors tested under pressure ranging from 0 to 50 bar at five different temperatures indicate a linear output with a typical sensitivity of approximately 16 mV/V/bar, a maximum zero shift of 0.05% FS, and a span shift of 0.03% FS. The higher output level of pressure sensing gauges will provide greater signal strength, thus maintaining a better signal-to-noise ratio than conventional pressure sensors. The offset and span shift curves are quite linear across the operating temperature range, giving the end user the advantage of using very simple algorithms for temperature compensation of offset and span shift.

RESUMEN

BACKGROUND: After discharge from an acute care hospitalization, patients with cancer may choose to pursue rehabilitative care in a skilled nursing facility (SNF). The objective of this study was to examine receipt of anticancer therapy, death, readmission, and hospice use among patients with cancer who discharge to an SNF compared with those who are functionally able to discharge to home or home with home healthcare in the 6 months after an acute care hospitalization. METHODS: A population-based cohort study was conducted using the SEER-Medicare database of patients with stage II-IV colorectal, pancreatic, bladder, or lung cancer who had an acute care hospitalization between 2010 and 2013. A total of 58,770 cases were identified and patient groups of interest were compared descriptively using means and standard deviations for continuous variables and frequencies and percentages for categorical variables. Logistic regression was used to compare patient groups, adjusting for covariates. RESULTS: Of patients discharged to an SNF, 21%, 17%, and 2% went on to receive chemotherapy, radiotherapy, and targeted chemotherapy, respectively, compared with 54%, 28%, and 6%, respectively, among patients discharged home. Fifty-six percent of patients discharged to an SNF died within 6 months of their hospitalization compared with 36% discharged home. Thirty-day readmission rates were 29% and 28% for patients discharged to an SNF and home, respectively, and 12% of patients in hospice received <3 days of hospice care before death regardless of their discharge location. CONCLUSIONS: Patients with cancer who discharge to an SNF are significantly less likely to receive subsequent oncologic treatment of any kind and have higher mortality compared with patients who discharge to home after an acute care hospitalization. Further research is needed to understand and address patient goals of care before discharge to an SNF.

RESUMEN

Latinos are more likely to experience uncontrolled pain, and institutional death, and are less likely to engage in advance care planning. Efforts to increase access to palliative care must maximize primary palliative care and community based models to meet the ever-growing need in a culturally sensitive and congruent manner. Patient navigator interventions are community-based, culturally tailored models of care that have been successfully implemented to improve disease prevention, early diagnosis, and treatment. We have developed a patient navigation intervention to improve palliative care outcomes for seriously ill Latinos. We describe the protocol for a National Institute of Nursing Research-funded randomized controlled trial designed to determine the effectiveness of the manualized patient navigator intervention. We aim to enroll 240 Latino adults with non-cancer, advanced medical illness from both urban and rural clinical sites. Participants will be randomized to the intervention group (five palliative care patient navigator visits plus bilingual educational materials) or control group (usual care plus bilingual educational materials). Outcomes include quality of life (Functional Assessment of Chronic Illness Therapy), advance care planning (Advance Care Planning Engagement survey), pain (Brief Pain Inventory), symptom management (Edmonton Symptom Assessment Scale-revised), hospice utilization, and cost and utilization of healthcare resources. This culturally tailored, evidence-based, theory-driven, innovative patient navigation intervention has significant potential to improve palliative care for Latinos, and facilitate health equity in palliative and end-of-life care.

RESUMEN

Background: We present and describe tailored strategies to address known barriers to minority participation in clinical trial research. The strategies used allowed our team to engage communities and successfully recruit, enroll, and retain a diverse underserved population of Latinos with advanced cancer for this clinical trial. Methods: Participants were recruited from 3 urban and 7 rural sites. We identified 4 critical barriers to recruitment for this underserved population: (1) mistrust; (2) language and communication barriers; (3) lack of access to academic cancer center; and (4) inability to participate due to transportation, childcare, or work responsibilities. We developed tailored strategies to engage referring sites and patients to participate in the clinical trial. Results: We identified 318 potentially eligible participants; 34 were found to be ineligible, and 223 consented to participate in the study, representing a 79.0% enrollment rate. All patients (100%) self-identified as Latino, and 47.5% spoke Spanish as their primary language. Patients were socioeconomically disadvantaged: 53.6% had an annual income <$15,000 USD, and 50.2% had less than a high school education. A total of 177 participants completed the 3-month follow-up; 26 died before the 3-month follow interview, and 20 did not complete the follow-up evaluation (9% withdrawal rate). Conclusions: Our community-informed strategies were highly effective for recruiting, enrolling, and retaining an underserved diverse population of Latinos. The barriers we identified and the strategies we used have the potential to inform research to increase minority participation in cancer clinical trials. ClinicalTrials.gov identifier: NCT01695382.

RESUMEN

BACKGROUND AND OBJECTIVES: In Colorado, marijuana was legalized for medical use in 2000, commercialized in 2009, and approved for recreational purposes in 2012. Little is known about the association between recent policy changes and adolescent substance treatment outcomes measured by urine drug screens (UDS). This study addressed this research gap. METHODS: Participants were youth (N = 523) aged 11-19 years who were enrolled in an outpatient motivational interviewing (MI)/cognitive behavioral therapy (CBT) plus contingency management (CM) in Denver, Colorado from October 2007 to June 2014. The measures included UDS collected during weekly treatment sessions and sent to a commercial laboratory for quantitative analysis of tetrahydrocannabinol (THC)/Creatinine (Cr). Linear regression models and logistic regression models using a Generalized Estimating Equations (GEE) approach for repeated measures were completed to answer the study aims. RESULTS: Males, but not females, had a marginally significant increasing trend over time in monthly average THC/Cr (ß = 1.99, p = 0.046). There was a significant increasing trend over time (per 30 days) in the odds of having a negative UDS within 6 sessions (OR = 1.02, 95%CI = 1.003-1.04, p = 0.006). CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: Based on these data, substance treatment outcomes from MI and CBT are mixed, but overall treatment appears to remain effective in a state with legalized marijuana.

RESUMEN

BACKGROUND: Chronic opioid therapy for chronic pain treatment has increased. Hospital physicians, including hospitalists and medical/surgical resident physicians, care for many hospitalized patients, yet little is known about opioid prescribing at hospital discharge and future chronic opioid use. OBJECTIVE: We aimed to characterize opioid prescribing at hospital discharge among 'opioid naïve' patients. Opioid naïve patients had not filled an opioid prescription at an affiliated pharmacy 1 year preceding their hospital discharge. We also set out to quantify the risk of chronic opioid use and opioid refills 1 year post discharge among opioid naïve patients with and without opioid receipt at discharge. DESIGN: This was a retrospective cohort study. PARTICIPANTS: From 1 January 2011 to 31 December 2011, 6,689 opioid naïve patients were discharged from a safety-net hospital. MAIN MEASURE: Chronic opioid use 1 year post discharge. KEY RESULTS: Twenty-five percent of opioid naïve patients (n = 1,688) had opioid receipt within 72 hours of discharge. Patients with opioid receipt were more likely to have diagnoses including neoplasm (6.3% versus 3.5%, p < 0.001), acute pain (2.7% versus 1.0 %, p < 0.001), chronic pain at admission (12.1% versus 3.3%, p < 0.001) or surgery during their hospitalization (65.1% versus 18.4%, p < 0.001) compared to patients without opioid receipt. Patients with opioid receipt were less likely to have alcohol use disorders (15.7% versus 20.7%, p < 0.001) and mental health disorders (23.9% versus 31.4%, p < 0.001) compared to patients without opioid receipt. Chronic opioid use 1 year post discharge was more common among patients with opioid receipt (4.1% versus 1.3%, p < 0.0001) compared to patients without opioid receipt. Opioid receipt was associated with increased odds of chronic opioid use (AOR = 4.90, 95% CI 3.22-7.45) and greater subsequent opioid refills (AOR = 2.67, 95% CI 2.29-3.13) 1 year post discharge compared to no opioid receipt. CONCLUSION: Opioid receipt at hospital discharge among opioid naïve patients increased future chronic opioid use. Physicians should inform patients of this risk prior to prescribing opioids at discharge.

RESUMEN

OBJECTIVE: We evaluated integrating a motivational interviewing (MI)-based smoking cessation curricula and MI counseling into a posttraumatic stress disorder (PTSD) home telehealth care management program to determine if smoking behaviors improved. METHOD: We randomized 178 Veterans with PTSD to a 90-session MI-based home telehealth program or to usual care. Outcome measures included self-reported 24-hour quit attempts, seven-day point prevalence abstinence, progression along the stages of change, and mental health symptoms. RESULTS: Favorable smoking cessation rates were observed in both groups. There was no statistical difference in self-reported 24-hour quit attempts, seven-day point prevalence smoking abstinence or progression along the stages of change. The intervention group showed improved depression and PTSD symptoms. CONCLUSION: Integrating MI-based smoking cessation treatment into PTSD home telehealth is an effective method to help Veterans with PTSD quit smoking. Further research is needed to understand how to optimize MI integration into home telehealth to achieve sustained smoking cessation rates.

RESUMEN

Serotonin (5-hydroxytryptamine; 5-HT) is a CNS neurotransmitter increasingly recognized to exert immunomodulatory effects outside the CNS that contribute to the pathogenesis of autoimmune and chronic inflammatory diseases. 5-HT signals to activate the RhoA/Rho kinase (ROCK) pathway, a pathway known for its ability to regulate phagocytosis. The clearance of apoptotic cells (i.e. efferocytosis) is a key modulator of the immune response that is inhibited by the RhoA/ROCK pathway. Because efferocytosis is defective in many of the same illnesses where 5-HT has been implicated in disease pathogenesis, we hypothesized that 5-HT would suppress efferocytosis via activation of RhoA/ROCK. The effect of 5-HT on efferocytosis was examined in murine peritoneal and human alveolar macrophages, and its mechanisms were investigated using pharmacologic blockade and genetic deletion. 5-HT impaired efferocytosis by murine peritoneal macrophages and human alveolar macrophages. 5-HT increased phosphorylation of myosin phosphatase subunit 1 (Mypt-1), a known ROCK target, and inhibitors of RhoA and ROCK reversed the suppressive effect of 5-HT on efferocytosis. Peritoneal macrophages expressed the 5-HT transporter and 5-HT receptors (R) 2a, 2b, but not 2c. Inhibition of 5-HTR2a and 5-HTR2b had no effect on efferocytosis, but blockade of the 5-HT transporter prevented 5-HT-impaired efferocytosis. Genetic deletion of the 5-HT transporter inhibited 5-HT uptake into peritoneal macrophages, prevented 5-HT-induced phosphorylation of Mypt-1, reversed the inhibitory effect of 5-HT on efferocytosis, and decreased cellular peritoneal inflammation. These results suggest a novel mechanism by which 5-HT might disrupt efferocytosis and contribute to the pathogenesis of autoimmune and chronic inflammatory diseases.

RESUMEN

BACKGROUND: Former prison inmates experience high rates of hospitalizations and death during the transition from prison to the community, particularly from drug-related causes and early after release. The authors designed a randomized controlled trial (RCT) of patient navigation to reduce barriers to health care and hospitalizations for former prison inmates. METHODS: Forty former prison inmates with a history of drug involvement were recruited and randomized within 15 days after prison release. Participants were randomized to receive 3 months of patient navigation (PN) with facilitated enrollment into an indigent care discount program (intervention) or facilitated enrollment into an indigent care discount program alone (control). Structured interviews were conducted at baseline, 3 months, and 6 months. Outcomes were measured as a change in self-reported barriers to care and as the rate of health service use per 100 person-days. RESULTS: The mean number of reported barriers to care was reduced at 3 and 6 months in both groups. At 6 months, the rate of emergency department/urgent care visits per 100 person-days since baseline was 1.1 among intervention participants and 0.5 among control participants (P = .04), whereas the rate of hospitalizations per 100 person-days was 0.2 in intervention participants and 0.6 in control participants (P = .04). CONCLUSIONS: Recruitment of former inmates into an RCT of patient navigation was highly feasible, but follow-up was limited by rearrests. Results suggest a significantly lower rate of hospitalizations among navigation participants, although the rate of emergency department/urgent care visits was not improved. Patient navigation is a promising, pragmatic intervention that may be effective at reducing high-cost health care utilization in former prison inmates.

RESUMEN

The aims of this study were to (a) describe the nature of patients' goals upon discharge from hospital, family caregivers' goals for their loved ones, and family caregivers' goals for themselves; (b) determine the degree of concordance with respect to the three elicited goals; (c) ascertain goal attainment across the three elicited goals; and (d) examine factors predictive of goal attainment. Our findings support the position that eliciting patient and family caregiver goals and promoting goal attainment may represent an important step toward promoting greater patient and family caregiver engagement in their care.

RESUMEN

Women in prison have a higher prevalence of HIV than men. After release from prison, former inmates have the opportunity to engage in risk behaviors for HIV and other sexually transmitted infections (STIs). We sought to assess change in risk behaviors over time and the association of gender with risk behavior in the postrelease period. In this prospective cohort study, we interviewed 200 former inmates (51 women) approximately two weeks (baseline) and three months (follow-up) after release and tested them for HIV infection at follow-up. We examined the association of gender with unprotected vaginal or anal sex in the last seven days using chi-square and Fisher's exact tests and multivariable logistic regression. At baseline, 22% of men and 41% of women reported unprotected vaginal sex (p < 0.01) and 5% of men and 8% of women reported unprotected anal sex (p = 0.51). Being younger (OR for each decade increase 0.48, 95% CI = 0.29-0.80), being gay/lesbian or being bisexual (compared with being heterosexual, OR = 4.74, 95% CI = 1.01-22.17 and OR = 3.98, 95% CI = 1.41-11.26, respectively), or reporting a drug of choice of heroin/speedballs or cocaine/crack (compared with marijuana/no drug of choice, OR = 24.00, 95% CI = 5.15-111.81 and OR = 3.49, 95% CI = 1.20-10.18, respectively) was associated with unprotected vaginal or anal sex after adjusting for race, homelessness, and hazardous drinking. At follow-up, 21% of men and 44% of women reported unprotected sex (p = 0.005), and female gender (OR = 4.42, 95% CI = 1.79-10.94) and hazardous drinking (compared with not meeting criteria for hazardous drinking, OR = 3.64, 95% CI = 1.34-9.86) were associated with unprotected sex, adjusting for race and homelessness. In this population with a high prevalence of HIV, we demonstrated persistent engagement in sexual risk behavior during the postrelease period. Enhanced efforts to promote sexual health and reduced risk behavior among both male and female current and former prison inmates are needed, including improved access to preventive care and HIV and STI screening, testing, and treatment.

RESUMEN

Importance: Disparities persist across the trajectory of serious illness, including at the end of life. Patient navigation has been shown to reduce disparities and improve outcomes for underserved populations. Objective: To determine the effectiveness of a lay patient navigator intervention, Apoyo con Cariño, in improving palliative care outcomes among Hispanic patients. Design, Setting, and Participants: This was a multicenter randomized clinical trial that took place across academic, nonprofit, safety-net, and community health care systems in urban, rural, and mountain/frontier regions of Colorado from January 2017 to January 2021. Self-identifying Hispanic adults with serious noncancer medical illness and limited prognosis were recruited. Data were collected and analyzed from July 2022 to July 2023. Interventions: Participants randomized to the intervention group received 5 home visits from a bilingual, bicultural lay patient navigator; participants randomized to control received care as usual. Both groups received culturally tailored educational materials. Investigators/outcome accessors remained blinded to participant assignment. Main Outcomes and Measures: Change in score from baseline to 3 months on the Functional Assessment of Chronic Illness Therapy (FACIT) General quality of life (QOL) scale (primary outcome), Advance Care Planning (ACP) Engagement Survey, Brief Pain Inventory, Edmonton Symptom Assessment Scale, and FACIT Spiritual Well-Being subscale; at 6 months, advance directive (AD) documentation; and at 46 months or death, hospice utilization and length of stay, as well as aggressiveness of care at end of life. Results: Of 209 patients enrolled (mean [SD] age, 63.6 [14.3] years; 108 [51.7%] male), 105 patients were randomized to control and 104 patients to the intervention. There were no statistically significant differences in the change in mean (SD) QOL score between the intervention and control groups (5.0 [16.5] vs 4.3 [15.5]; P = .75). Participants in the intervention group, compared with the control group, had statistically significant greater increases in mean (SD) ACP engagement (0.8 [1.3] vs 0.1 [1.4]; P < .001) and were more likely to have a documented AD (62 of 104 [59.6%] vs 28 of 105 [26.9%]; P < .001). There were no statistically significant differences in mean (SD) change in pain intensity score (0-10) between patients in the intervention group compared with control (-0.4 [2.6] vs -0.5 [2.8]; P = .79), nor pain interference (-0.2 [3.7] vs -0.4 [3.7]; P = .71). Patients receiving the intervention were more likely to be referred to hospice compared with patients receiving control (19 of 43 patients [44.2%] vs 7 of 33 patients [21.2%]; P = .04) and less likely to receive aggressive care at end of life (27 of 42 patients [64.3%] vs 28 of 33 patients [84.8%]; P = .046). Conclusion and Relevance: In this randomized clinical trial, a culturally tailored patient navigator intervention did not improve QOL for patients. However, the intervention did increase ACP engagement, AD documentation, and hospice utilization in Hispanic persons with serious medical illness. Trial Registration: ClinicalTrials.gov Identifier: NCT03181750.

RESUMEN

BACKGROUND AND OBJECTIVES: The longitudinal risk for human immunodeficiency virus (HIV) infection following adolescent substance treatment is not known. Therefore, it is not known if adolescent substance treatment should include HIV prevention interventions. To address this important research gap, this study evaluates the longitudinal prevalence and predictors of injection drug use (IDU) and sex risk behaviors among adolescents in substance treatment. METHODS: Participants were 260 adolescents (13-18 years) in substance treatment and 201 community control adolescents (11-19 years). Participants were assessed at baseline and follow-up (mean time between assessments = 6.9 years for the clinical sample and 5.6 years for the community control sample). Outcomes included self-report lifetime history of IDU, number of lifetime sex partners and frequency of unprotected sexual intercourse. RESULTS: At baseline, 7.5% of the clinical sample, compared to 1.0% of the community control sample had a lifetime history of IDU (χ12=10.53, p = .001). At follow-up, 17.4% of the clinical sample compared to 0% of the community control sample had a lifetime history of IDU (χ12=26.61, p = .0005). The number of baseline substance use disorders and onset age of marijuana use significantly predicted the presence of lifetime IDU at follow-up, after adjusting for baseline age, race, and sex. The clinical sample reported more lifetime sex partners and more frequent unprotected sex than the community control sample at baseline and follow-up. CONCLUSIONS: Many adolescents in substance treatment develop IDU and report persistent risky sex.

RESUMEN

BACKGROUND: Asthma exacerbations with respiratory failure (AERF) are associated with hospital mortality of 7% to 15%. Extracorporeal membrane oxygenation (ECMO) has been used as a salvage therapy for refractory AERF, but controlled studies showing its association with mortality have not been performed. RESEARCH QUESTION: Is treatment with ECMO associated with lower mortality in refractory AERF compared with standard care? STUDY DESIGN AND METHODS: This is a retrospective, epidemiologic, observational cohort study using a national, administrative data set from 2010 to 2020 that includes 25% of US hospitalizations. People were included if they were admitted to an ECMO-capable hospital with an asthma exacerbation, and were treated with short-acting bronchodilators, systemic corticosteroids, and invasive ventilation. People were excluded for age < 18 years, no ICU stay, nonasthma chronic lung disease, COVID-19, or multiple admissions. The main exposure was ECMO vs No ECMO. The primary outcome was hospital mortality. Key secondary outcomes were ICU length of stay (LOS), hospital LOS, time receiving invasive ventilation, and total hospital costs. RESULTS: The study analyzed 13,714 patients with AERF, including 127 with ECMO and 13,587 with No ECMO. ECMO was associated with reduced mortality in the covariate-adjusted (OR, 0.33; 95% CI, 0.17-0.64; P = .001), propensity score-adjusted (OR, 0.36; 95% CI, 0.16-0.81; P = .01), and propensity score-matched models (OR, 0.48; 95% CI, 0.24-0.98; P = .04) vs No ECMO. Sensitivity analyses showed that mortality reduction related to ECMO ranged from OR 0.34 to 0.61. ECMO was also associated with increased hospital costs in all three models (P < .0001 for all) vs No ECMO, but not with decreased ICU LOS, hospital LOS, or time receiving invasive ventilation. INTERPRETATION: ECMO was associated with lower mortality and higher hospital costs, suggesting that it may be an important salvage therapy for refractory AERF following confirmatory clinical trials.

RESUMEN

OBJECTIVE: Older hospitalized adults with an existing diagnosis of cancer rarely receive cancer treatment after discharge to a skilled nursing facility (SNF). It is unclear to what degree these outcomes may be driven by cumulative effects of previous cancer treatment and their complications vs an absolute functional threshold from which it is not possible to return. We sought to understand post-acute care outcomes of adults newly diagnosed with cancer and explore functional improvement during their SNF stay. DESIGN: Retrospective cohort study, 2011-2013. SETTING AND PARTICIPANTS: Surveillance, Epidemiology, and End Results - Medicare database of patients with new stage II-IV colorectal, pancreatic, bladder, or lung cancer discharged to SNF. METHODS: Primary outcome was time to death after hospital discharge. Covariates include cancer treatment receipt and hospice use. A Minimum Data Set (MDS)-Activities of Daily Living (ADL) score was calculated to measure changes in ADLs during SNF stay. Patient groups of interest were compared descriptively using means and standard deviations for continuous variables and frequencies and percentages for categorical variables. Logistic regression was used to compare patient groups. RESULTS: A total of 6791 cases were identified. Forty-six percent of patients did not receive treatment or hospice, 25.0% received no treatment but received hospice, 20.8% received treatment but no hospice, and 8.5% received both treatment and hospice. Only 43% of decedents received hospice. Patients who received treatment but not hospice had the best survival. There were limited improvements in MDS-ADL scores in the subset of patients for whom we have complete data. Those with greater functional improvement had improved survival. CONCLUSIONS AND IMPLICATIONS: The majority of patients did not receive future cancer treatment or hospice care prior to death. There was limited improvement in MDS-ADL scores raising concern this population might not benefit from the rehabilitative intent of SNFs.

RESUMEN

BACKGROUND: Twenty-five percent to 45% of COPD is caused by exposures other than active smoking. Secondhand tobacco smoke (SHS) has been suggested as an independent cause of COPD, based on its association with increased respiratory symptoms and a small decrease in lung function, but its impact on respiratory health and lung function after exposure cessation has not been explored. RESEARCH QUESTION: What are the consequences of airline SHS exposure on respiratory health and lung function decades after cessation? STUDY DESIGN AND METHODS: We performed a cohort study involving flight attendants because of their exposure to SHS that stopped > 20 years ago. We included subjects ≥ 50 years of age with > 1 year vs ≤ 1 year of airline SHS exposure (ie, exposed vs unexposed). Respiratory quality of life, as determined by the St. George's Respiratory Questionnaire (SGRQ), was the primary outcome for respiratory health. Key secondary outcomes included general quality of life (the Rand Corporation modification of the 36-item Short Form Health Survey Questionnaire; RAND-36), respiratory symptoms (COPD Assessment Test; CAT), and spirometry. RESULTS: The study enrolled 183 SHS-exposed and 59 unexposed subjects. Exposed subjects were 66.7 years of age, and 90.7% were female. They were hired at 23.8 years of age, were exposed to airline SHS for 16.1 years, and stopped exposure 27.5 years before enrollment. Prior SHS exposure was associated with worsened SGRQ (6.7 units; 95% CI, 2.7-10.7; P = .001), RAND-36 physical and social function, and CAT vs unexposed subjects. SHS exposure did not affect prebronchodilator spirometry or obstruction, but was associated with lower postbronchodilator FEV1 and FEV1/FVC, total lung capacity, and diffusing capacity of the lungs for carbon monoxide in a subset of subjects. Former smoking and SHS exposure synergistically worsened SGRQ (ß = 8.4; 95% CI, 0.4-16.4; P = .04). SHS exposure in people who never smoked replicated primary results and was associated with worsened SGRQ vs unexposed people (4.7 units; 95% CI, 0.7-7.0; P = .006). INTERPRETATION: Almost three decades after exposure ended, airline SHS exposure is strongly and dose-dependently associated with worsened respiratory health, but less robustly associated with airflow abnormalities used to diagnose COPD.

RESUMEN

OBJECTIVE: The objectives of this study were to demonstrate the feasibility of telehealth technology to provide a team approach to diabetes care for rural patients and determine its effect on patient outcomes when compared with face-to-face diabetes visits. MATERIALS AND METHODS: An evaluation of a patient-centered interdisciplinary team approach to diabetes management compared telehealth with face-to-face visits on receipt of recommended preventive guidelines, vascular risk factor control, patient satisfaction, and diabetes self-management at baseline and 1, 2, and 3 years postintervention. RESULTS: One-year postintervention the receipt of recommended dilated eye exams increased 31% and 43% among telehealth and face-to-face patients, respectively (p=0.28). Control of two or more risk factors increased 37% and 69% (p=0.21). Patient diabetes care satisfaction rates increased 191% and 131% among telehealth and face-to-face patients, respectively (p=0.51). A comparison of telehealth with face-to-face patients resulted in increased self-reported blood glucose monitoring as instructed (97% vs. 89%; p=0.63) and increased dietary adherence (244% vs. 159%; p=0.86), respectively. Receipt of a monofilament foot test showed a significantly greater improvement among face-to-face patients (17% vs. 35%; p=0.01) at 1 year postintervention, but this difference disappeared in years 2 and 3. CONCLUSIONS: Telehealth proved to be an effective mode for the provision of diabetes care to rural patients. Few differences were detected in the delivery of a team approach to diabetes management via telehealth compared with face-to-face visits on receipt of preventive care services, vascular risk factor control, patient satisfaction, and patient self-management. A team approach using telehealth may be a viable strategy for addressing the unique challenges faced by patients living in rural communities.

RESUMEN

RATIONALE: Rural chronic obstructive pulmonary disease (COPD) patients have worse outcomes and higher mortality compared with urban patients. Reasons for these disparities likely include challenges to delivery of care that have not been explored. OBJECTIVE: To determine challenges faced by rural primary care providers when caring for COPD patients. METHODS: Rural primary care providers in 7 primarily western states were asked about barriers they experienced when caring for COPD patients. RESULTS: A total of 71 rural primary care medical providers completed the survey, of which 51% were physicians and 49% were advanced practice providers (APPs). A total of 61% used Global Initiative for Chronic Obstructive Lung Disease or American Thoracic Society/European Respiratory Society guidelines as an assessment and treatment resource. The presence of multiple chronic conditions and patient failure to recognize and report symptoms were the greatest barriers to diagnose COPD. A total of 89% of providers used spirometry to diagnose COPD, but only 62% were satisfied with access to spirometry. Despite recommendations, 41% of providers never test for alpha-1 antitrypsin deficiency. A total of 87% were comfortable with their ability to assess symptoms, but only 11% used a guideline-recommended assessment tool. Although most providers were satisfied with their ability to treat symptoms and exacerbations, only 66% were content with their ability to prevent exacerbations. Fewer providers were happy with their access to pulmonologists (55%) or pulmonary rehabilitation (37%). Subgroup analyses revealed differences based on provider type (APP versus physician) and location (Colorado and Kansas versus other states), but not on population or practice size. CONCLUSIONS: Rural providers face significant challenges when caring for COPD patients that should be targeted in future interventions to improve COPD outcomes.
