A Wearable System for Continuous Monitoring and Assessment of Speech, Gait, and Cognitive Decline for Early Diagnosis of ADRD.

Early detection of cognitive decline is essential to study mild cognitive impairment and Alzheimer's Disease in order to develop targeted interventions and prevent or stop the progression of dementia. This requires continuous and longitudinal assessment and tracking of the related physiological and behavioral changes during daily life. In this paper, we present a low cost and low power wearable system custom designed to track the trends in speech, gait, and cognitive stress while also considering the important human factor needs such as privacy and compliance. In the form factors of a wristband and waist-patch, this multimodal, multi-sensor system measures inertial signals, sound, heart rate, electrodermal activity and pulse transit time. A total power consumption of 2.6 mW without any duty cycling allows for more than 3 weeks of run time between charges when 1500 mAh batteries are used.Clinical Relevance- Much earlier detection of Alzheimer's disease and related dementias may be possible by continuous monitoring of physiological and behavioral state using application specific wearable sensors during the activities of daily life.

Analysis of Postpartum Uptake of Long-Acting Reversible Contraceptives Before and After Implementation of Medicaid Reimbursement Policy.

OBJECTIVES: The postpartum period is a time of high unmet contraception need. Providing long-acting reversible contraception (LARC), particularly in the immediate postpartum period, is one strategy to meet contraceptive needs. This practice may also prevent unintended and short interpregnancy interval pregnancies. In recent years, state Medicaid programs have implemented reimbursement policies for LARC use in the inpatient setting. The purpose of this study was to assess the uptake of inpatient postpartum LARCs at a large urban hospital with a sizable Medicaid population, before and after policy implementation. METHODS: Using billing records from January 2015 and December 2017, we extracted data on patient demographics and LARC uptake before Medicaid policy change (2015) and after policy change (2016 and 2017). Implant and intrauterine device insertions were classified as inpatient postpartum (0-7 days after birth), outpatient postpartum (1-8 weeks after) or interval (9+ weeks after). RESULTS: In the 3-year study period, 2091 LARC insertions occurred, of which 700 (33.5%) were inpatient postpartum, 429 (20.5%) outpatient postpartum, and 962 (46.0%) interval. After policy implementation, inpatient postpartum LARC insertions increased from 2.6 per 100 deliveries to 16.8 per 100 deliveries. Significant differences in uptake were seen in Black and Hispanic populations. The number of outpatient postpartum LARCs remained stable and tubal sterilizations decreased. CONCLUSIONS FOR PRACTICE: Implementation of reimbursement policies contributed to a sharp uptake of inpatient postpartum LARCs. Improved access to effective, reversible contraception could reduce the number of unplanned and short interpregnancy interval pregnancies, ultimately lowering rates of maternal morbidity and mortality.

Poor Access to Opioid Addiction Care for Total Joint Arthroplasty Patients.

INTRODUCTION: The United States is experiencing an opioid epidemic, and orthopedists prescribe a large proportion of these drugs. Patients often become dependent on painkillers and face barriers to treatment. Given that many joint arthroplasty patients are enrolled in Medicare, we aimed to examine the ease of orthopedic patients with various insurance types to access addiction and pain specialists. METHODS: Using three web-based directories, we identified addiction specialists within a 5-mile radius of our hospital. We contacted these practices and inquired as to whether they treated addiction, types of insurance they accepted, and appointment availability. RESULTS: We identified 190 addiction and pain management specialists and were able to reach 134/190 (70.5%). Nine (6.7%) of the 134 reachable physicians accepted Medicare or Medicaid, which is nine (4.7%) of the 190 physicians initially located. The average wait time to an appointment was 4.2 days, and a significant difference in wait time existed across insurance types (p = 0.0284). DISCUSSION: Orthopedic patients face many barriers to receiving treatment for painkiller addiction. Wait time to see an addiction specialist also varied based on insurance type. Online directories may not be useful for certain patient populations to identify physicians. Orthopedic surgeons should partner with addiction and pain specialists to help alleviate the barriers that patients face.

Right Here Right Now (RHRN) pilot study: testing a method of near-real-time data collection on the social determinants of health.

BACKGROUND: Informing policy and practice with up-to-date evidence on the social determinants of health is an ongoing challenge. One limitation of traditional approaches is the time-lag between identification of a policy or practice need and availability of results. The Right Here Right Now (RHRN) study piloted a near-real-time data-collection process to investigate whether this gap could be bridged. METHODS: A website was developed to facilitate the issue of questions, data capture and presentation of findings. Respondents were recruited using two distinct methods - a clustered random probability sample, and a quota sample from street stalls. Weekly four-part questions were issued by email, Short Messaging Service (SMS or text) or post. Quantitative data were descriptively summarised, qualitative data thematically analysed, and a summary report circulated two weeks after each question was issued. The pilot spanned 26 weeks. RESULTS: It proved possible to recruit and retain a panel of respondents providing quantitative and qualitative data on a range of issues. The samples were subject to similar recruitment and response biases as more traditional data-collection approaches. Participants valued the potential to influence change, and stakeholders were enthusiastic about the findings generated, despite reservations about the lack of sample representativeness. Stakeholders acknowledged that decision-making processes are not flexible enough to respond to weekly evidence. CONCLUSION: RHRN produced a process for collecting near-real-time data for policy-relevant topics, although obtaining and maintaining representative samples was problematic. Adaptations were identified to inform a more sustainable model of near-real-time data collection and dissemination in the future.
