Assessment of Fall-Related Emergency Medical Service Calls and Transports after a Community-Level Fall-Prevention Initiative.

Background: Getting effective fall prevention into the homes of medically and physically vulnerable individuals is a critical public health challenge. Community paramedicine is emerging globally as a new model of care that allows emergency medical service units to evaluate and treat patients in non-emergency contexts for prevention efforts and chronic care management. The promise of community paramedicine as a delivery system for fall prevention that scales to community-level improvements in outcomes is compelling but untested.Objective: To study the impact of a community paramedic program's optimization of a fall prevention system entailing a clinical pathway and learning health system (called Community-FIT) on community-level fall-related emergency medical service utilization rates.Methods: We used an implementation science framework and quality improvement methods to design and optimize a fall prevention model of care that can be embedded within community paramedic operations. The model was implemented and optimized in an emergency medical service agency servicing a Midwestern city in the United States (∼35,000 residents). Primary outcome measures included relative risk reduction in the number of community-level fall-related 9-1-1 calls and fall-related hospital transports. Interrupted time series analysis was used to evaluate relative risk reduction from a 12-month baseline period (September 2016 - August 2017) to a 12-month post-implementation period (September 2018-August 2019).Results: Community paramedic home visits increased from 25 in 2017, to 236 in 2018, to 517 in 2019, indicating a large increase in the number of households that benefited from the efforts. A relative risk reduction of 0.66 (95% [CI] 0.53, 0.76) in the number of fall calls and 0.63 (95% [CI] 0.46, 0.75) in the number of fall-related calls resulting in transports to the hospital were observed.Conclusions: Community-FIT may offer a powerful mechanism for community paramedics to reduce fall-related 9-1-1 calls and transports to hospitals that can be implemented in emergency medical agencies across the country.

Uncoupling protein 3 deficiency impairs myocardial fatty acid oxidation and contractile recovery following ischemia/reperfusion.

Patients with insulin resistance and type 2 diabetes have poor cardiac outcomes following myocardial infarction (MI). The mitochondrial uncoupling protein 3 (UCP3) is down-regulated in the heart with insulin resistance. We hypothesized that decreased UCP3 levels contribute to poor cardiac recovery following ischemia/reperfusion (I/R). After confirming that myocardial UCP3 levels were systematically decreased by 20-49% in animal models of insulin resistance and type 2 diabetes, we genetically engineered Sprague-Dawley rats with partial loss of UCP3 (ucp3+/-). Wild-type littermates (ucp3+/+) were used as controls. Isolated working hearts from ucp3+/- rats were characterized by impaired recovery of cardiac power and decreased long-chain fatty acid (LCFA) oxidation following I/R. Mitochondria isolated from ucp3+/- hearts subjected to I/R in vivo displayed increased reactive oxygen species (ROS) generation and decreased respiratory complex I activity. Supplying ucp3+/- cardiac mitochondria with the medium-chain fatty acid (MCFA) octanoate slowed electron transport through the respiratory chain and reduced ROS generation. This was accompanied by improvement of cardiac LCFA oxidation and recovery of contractile function post ischemia. In conclusion, we demonstrated that normal cardiac UCP3 levels are essential to recovery of LCFA oxidation, mitochondrial respiratory capacity, and contractile function following I/R. These results reveal a potential mechanism for the poor prognosis of type 2 diabetic patients following MI and expose MCFA supplementation as a feasible metabolic intervention to improve recovery of these patients at reperfusion.

Timing of emergency medical services activations for falls.

Objective: Falls are a major challenge to public health, particularly among older adults. Understanding factors that influence fall risk is pivotal in the prevention of falls and fall-related injuries. This study evaluated the timing of emergency medical service (EMS) activations for falls and transport patterns for adults age ≥65. Methods: A patient care report system at a single fire-based emergency medical service agency in a suburban, Midwest city was retrospectively reviewed. Type of call (lift assist/fall), time of injury (time, day, and month), and demographics (sex, age) were collected for residents age ≥65 who activated 9-1-1 for a lift assist or fall. Results: 1169 calls met inclusion criteria. Mornings and afternoons were the time of day associated with falls (33 % and 36 % of EMS activations, respectively, vs. 21 % and 10 % for evenings and nights, respectively; p = 0.002) while day of the week and month were not associated with falls or lift assists. More males requested lift assists than females (256 vs. 238) and more females called for falls than males (408 vs. 267; p < 0.001). Falls were more likely to be associated with transport to the hospital than lift assists (78% vs. 7 %). Female sex was associated with increased risk for transport to the hospital (60 % of females vs. 40 % of males; p < 0.001). Conclusions: Mornings and afternoons were associated with increased risk for falls and sex (female) with increased risk for transport to the hospital.

Impact of vision impairment on discharge destination for patients with hip fracture.

Introduction: Vision impairment (VI) due to low vision or blindness is a major sensory health problem affecting quality of life and contributing to increased risk of falls and hip fractures (HF). Up to 60% of patients with hip fracture have VI, and VI increases further susceptibility to falls due to mobility challenges after HF. We sought to determine if VI affects discharge destination for patients with HF. Materials and methods: Cross-sectional analysis of 2015 Inpatient Medicare claims was performed and VI, blindness/low vision), HF and HF surgery were identified using ICD-9, and ICD-10 codes. Patients who sustained a HF with a diagnosis of VI were categorized as HF + VI. The outcome measure was discharge destination of home, skilled nursing facility (SNF), long-term care facility (LTCF) or other. Results: During the one-year ascertainment of inpatient claims, there were 10,336 total HF patients, 66.82% female, 91.21% non-Hispanic white with mean (standard deviation) age 82.3 (8.2) years. There was an age-related increase in diagnosis of VI with 1.49% (29/1941) of patients aged 65-74, 1.76% (63/3574) of patients aged 75-84, and 2.07% (100/4821) of patients aged 85 and older. The prevalence of VI increased with age, representing 1.5% (29/1941) of adults aged 65-74, 1.8% (63/3574) of adults aged 75-84, and 2.1% (100/4821) of adults aged 85 and older. The age-related increase in VI was not significant (P = 0.235). Patients with HF were most commonly discharged to a SNF (64.46%), followed by 'Other' (25.70%), home (7.15%), and LTCF (2.67%). VI was not associated with discharge destination. Male gender, Black race, systemic complications, and late postoperative discharge significantly predicted discharge to LTCF with odds ratios (95%CI) 1.42 (1.07-1.89), 1.90 (1.13-3.18), 2.27 (1.66-3.10), and 1.73 (1.25-2.39) respectively. Conclusions: The co-morbid presence of VI was not associated with altered discharge destinations to home, skilled nursing facility, LTCF or other setting.

The role of community paramedicine in fall prevention: A SWOT analysis.

BACKGROUND: Millions of older US adults fall annually, leading to catastrophic injuries, over 32,000 deaths and healthcare costs of over $55 billion. This study evaluated perceived benefits and limitations of using community paramedicine for fall prevention strategies from the lens of older adults, caregivers, and healthcare providers. METHODS: Semi-structured focus groups were held with individuals from three stakeholder groups: (1) community-dwelling older adults (age ≥60), (2) caregivers, and (3) healthcare providers. The Strengths-Weaknesses-Opportunities-Threats (SWOT) framework was used to quantitatively analyze stakeholder perceptions of using community paramedicine for fall prevention strategies. RESULTS: A total of 10 focus groups were held with 56 participants representing older adults (n = 15), caregivers (n = 16), and healthcare providers (n = 25). Community paramedicine was supported as a model of fall prevention by older adults, caregivers, and healthcare providers. Participants identified strengths such as visibility to the home environment, ability to implement home modifications, implicit trust in emergency medical services (EMS), and capacity to redirect resources toward prevention. Additionally, participants acknowledged opportunities such as providing continuity of care across the healthcare spectrum, improving quality and safety of care and potentially reducing unnecessary emergency department use. Participants endorsed weaknesses and threats such as funding, concerns of patients about stigma, and struggles with medical data integration. CONCLUSIONS: The results of this study illuminate the opportunity to leverage community paramedicine to address a variety of perceived barriers in order to design and implement better solutions for fall prevention efforts.

Timing of Complications Following Surgery for Distal Femur Fractures in Older Adults.

Introduction: The purpose of this study was to identify the timing and nature of complications associated with distal femur fracture surgery in patients aged 65 and older using the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database. Methods: The ACS NSQIP database was queried for adults aged 65 and older who received surgical treatment for a distal femur fracture between 01 January 2015 and 31 December 2021. Cox regression models and risk tables adjusted for baseline clinical characteristics were created for 14 complications (Superficial Surgical Site Infection (SSI), Deep SSI, Organ/Space SSI, Pneumonia, Pulmonary Embolism (PE), Deep Venous Thrombosis (DVT), Urinary Tract Infection (UTI), Stroke/Cerebrovascular accident (CVA), Myocardial Infarction (MI), Renal Failure, Cardiac Arrest (CA), Re-operation, Sepsis, and Death within 30 days of surgery). Model summaries were used to identify significant variables with a Bonferroni correction applied. Results: A total of 3956 adults met inclusion criteria and were included in analysis. The most common complications were UTI (5.2%), death (4.1%), and pneumonia (3.4%). Complications typically occurred within 14 days after surgery, except for SSI, which occurred between post-op days 11 and 24. Conclusions: Distal femur fractures are a substantial source of morbidity and mortality in the older adult population. Our findings underscore the need for comprehensive preoperative risk assessment and patient management strategies to mitigate the impact of identified risk factors in this vulnerable population.

Automated referral to community paramedicine during 9-1-1 fall calls for resource activation.

BACKGROUND: We sought to improve the referral process to a community paramedicine (CP) program following a 9-1-1 encounter. METHODS: An electronic health record (EHR) for CP records with the ability to link to emergency EHR was identified and implemented with a single-click referral to the CP program. Referrals were tracked for 15 months before and after implementation. RESULTS: Referral capacity increased from an average of 14.2 referrals per month to 44.9 referrals per month. CONCLUSION: The results of this study suggest an EHR is a useful investment for CP programs and may be integral to efficient program operations.

Barriers to the Initiation of Home Modifications for Older Adults for Fall Prevention.

INTRODUCTION: Home modifications are associated with decreased risk for falls and facilitate safe aging in place. The purpose of this study was to identify barriers to procurement of home modifications for older adults. MATERIALS AND METHODS: Cross-sectional interviews by 2 separate (1 male and 1 female) researchers in a Midwestern city of home repair ("handyman") and construction businesses within 15 miles of the areas of interest (neighborhood with a high socioeconomic status and neighborhood with low socioeconomic status) with a publicly listed phone number (n = 98). Estimated cost, earliest date of installation, and duration for a home modification project (installation of 3 grab bars) were collected. RESULTS: At least 1 response was attained only 43% of the time (n = 42), and residential grab bar installations were not provided by most businesses (n = 24). The average quote for materials and labor was $394.31 (range $125-$1300). Five of the 7 businesses that responded to both researchers with the same representative differed in cost estimates, generally offering a reduced quote for the low socioeconomic status neighborhood by as much as $300. Quotes provided to the female researcher were also higher than those obtained by the male researcher by about $30 regardless of socioeconomic status. The average wait for home modifications was 23 days and the average anticipated duration of the project was 2.6 hours. DISCUSSION: There are financial and procedural barriers to accessing home modifications for older adults who independently attempt to acquire them. There is a need for pathways in clinical and community settings to reduce barriers to home modifications to reduce the risk of falls. CONCLUSION: Home modifications are a promising tool to reduce falls and fall-related injuries in older adults. However, further work to identify cost-effective and timely options to reduce acquisition barriers is necessary to leverage the preventive power of home modifications.

The role of sociodemographics in the occurrence of orthopaedic trauma.

INTRODUCTION: We sought to determine the effects of sociodemographic factors on the occurrence of orthopaedic injuries in an adult population presenting to a level 1 trauma center. MATERIALS AND METHODS: We conducted a retrospective chart review of patients who received orthopaedic trauma care at a level 1 academic trauma center. RESULTS: 20,919 orthopaedic trauma injury cases were treated at an academic level 1 trauma center between 01 January 1993 and 27 August 2017. Following application of inclusion/exclusion criteria, a total of 14,654 patients were retrieved for analysis. Out of 14,654 patients, 4602 (31.4%) belonged to low socioeconomic status (SES), 4961 (32.0%) to middle SES and 5361 (36.6%) to high SES. Following adjustment for age, sex, race, insurance status and injury severity score (ISS), patients belonging to middle SES vs. low SES (OR 0.77 [95% CI 0.63-0.94]; p = 0.009) or high SES vs. low SES (OR 0.77 [95% CI 0.62-0.95]; p = 0.016) had lower odds of receiving a penetrating injury as compared to a blunt injury. CONCLUSION: The results from this study indicate that a link exists between sociodemographic factors and the occurrence of orthopaedic injuries presenting to a level 1 trauma center. The most common cause of injury varied within age groups, by sex, and within the different socioeconomic groups.
