Older Adults' Experiences in a Web-Based Intervention for Loneliness.

Background: Older adults may be vulnerable to loneliness due to natural and age-related transitions. Lonely older adults are at an increased risk of adverse health outcomes due to their loneliness, including cognitive decline, cardiovascular disease, and mortality. Objective: The purpose of this study was to explore the experiences of vulnerable older adults in a web-based loneliness intervention. Methods: Older adult participants in a web-based loneliness intervention (n = 24) participated in semi-structured interviews eliciting feedback about their experience in the program and perceived outcomes. Participants' responses were analyzed using qualitative content analysis. Results: Participants reported fewer negative perceptions of their social skills and future social interactions, gaining new social skills, improved relationships, and increased confidence to initiate and maintain social contact. Conclusions: Findings suggest the efficacy of combining a web-based loneliness intervention with cognitive behavioral therapy, and provide implications for future web-based interventions for older adult populations.

The association of resilience, social connections, and internal locus of control with pain outcomes among older adults.

Our objective was to investigate the hypothesis that psychological resources, including resilience, social connections, and internal locus of control, separately and in additive combinations, would be associated with selected pain outcomes: 1) days of opioid use and 2) medical/drug expenditures over 2 years. A mailed survey was sent to a stratified sample of older adults age≥65 with diagnosed back pain, osteoarthritis, and/or rheumatoid arthritis. Each of the resources was dichotomized as high/low and/or counted with equal weighting. Among respondents (N=3,131), the prevalence of mild/no and moderate/severe pain severity was 59% and 41%, respectively. As hypothesized, each resource was associated with lower levels of pain; additively, reported pain severity decreased as the number of resources increased. For moderate/severe pain, there was reduced opioid use among those with more resources; and, for mild/no pain, decreased medical/drug expenditures among those with ≥2 resources. Interventions that integrate psychological resources may enhance their effectiveness.

The association of physical activity with loneliness, social isolation, and selected psychological protective factors among older adults.

The primary objectives were to investigate the association of physical activity levels with 1) loneliness and social isolation; 2) protective factors: resilience, purpose-in-life, and perception of aging; and 3) the impact of these factors on healthcare expenditure patterns across physical activity levels. The study sample was identified from adults age ≥65 who completed a health survey in 2018 or 2019 (N=6,652). Among survey respondents, the prevalence of low, moderate, and high physical activity levels was 29%, 31%, and 41%, respectively. Moderate and high physical activity were associated with 15%-30% lower likelihoods of loneliness and social isolation; and with 27% to 150% higher protective factors. In addition, physical activity was associated with the mitigation of increased healthcare expenditures associated with loneliness, social isolation, and low levels of protective factors. Thus, physical activity could serve as an intervention to reduce loneliness and social isolation, augment protective factors, and mitigate excess healthcare expenditures.

Stapler Malfunctions in Bariatric Surgery: An Analysis of the MAUDE Database.

Background: Staple line leaks are a serious problem in bariatric surgery and a major cause of serious morbidity and mortality. Adverse events caused by medical devices are reported to the Food and Drug Administration which maintains the Manufacturer and User Facility Device Experience (MAUDE) database. We examined adverse stapler events reported to the MAUDE database, specifically with regards to bariatric surgery. Methods: The MAUDE database was queried for adverse events caused by staplers between January 1, 2018 - December 31, 2020; events reported by Intuitive, Ethicon, and Medtronic/Covidien; and limited our search to "gastric bypass", "sleeve gastrectomy", "stapler malfunction" combined with each company. Results: There were 883 adverse events reported for Medtronic, 353 for Ethicon, and 35 for Intuitive. Approximately 3.5 million staple reloads sold in the study period. The reported misfire rate for Medtronic was 0.04% and for Ethicon was 0.02%. Data for Intuitive was unavailable. The most common reported event for Medtronic was failure to fire (n = 349), followed by misfire (n = 186). For Ethicon, the most common event was failure to fire (n = 146), followed by mechanical problems (n = 27). The most common event with the Intuitive stapler was leak (n = 10) and bleeding from staple line (n = 8). Conclusions: Stapler malfunction is a very rare event in metabolic and bariatric surgery. All of the major stapler producers have transitioned to powered staplers with excellent safety profiles. Open and honest reporting about stapler malfunction is essential to determine the true safety of these ubiquitous devices.

The association of increasing resilience with positive health outcomes among older adults.

Our objective was to investigate three levels of resilience (low, medium, and high), identify associated characteristics, and measure the impact of increasing resilience on quality of life (QOL), healthcare utilization and expenditures, and preventive services compliance. The study sample was identified from adults age ≥65 who completed surveys during May-June 2019 (N=3,573). Other protective factors, including purpose-in-life, optimism, locus of control, and social connections, were dichotomized as high/low and counted with equal weighting (0 to 4). Among survey respondents, the prevalence of low, medium, and high resilience levels was 27%, 29%, and 44%, respectively. The strongest predictors of medium and high resilience included increasing number of other protective factors, lower stress, and no depression. Individuals with medium and high resilience had significantly higher QOL and lower healthcare utilization and expenditures. Resilience strategies integrated into healthy aging programming could be associated with improvements in QOL and/or healthcare utilization and expenditure outcomes.

Safety of liver biopsy at the time of bariatric surgery: an analysis of the MBSAQIP database.

BACKGROUND: The majority of patients undergoing bariatric surgery have hepatic steatosis. Liver biopsy is not technically difficult to perform at the time of metabolic and bariatric surgery (MBS), but there may be concerns for bleeding complications. The safety of liver biopsy (LBx) at the time of MBS has been studied in single institutional studies but has not been studied on a national level. METHODS: The MBSAQIP database for 2015-2018 was examined. The codes for Roux-en-Y gastric bypass (RYGB) of 43644 and sleeve gastrectomy (SG) 43775 were used along with 47000 (percutaneous liver biopsy), 47001 (percutaneous liver biopsy at time of other procedure), and 47379 (unlisted laparoscopic procedure, liver). Outcomes such as operative time, complications, and length of stay were examined. Propensity-matched analysis was performed to evaluate for adjusted associations. RESULTS: There were 546,532 patients that met our inclusion criteria. Of those, 21,367 (3.9%) underwent LBx. Only 5.5% (8012) of patients undergoing RYGB had a LBx and 3.3% (13,355) of SG patients. Patients who underwent a LBx had a longer operative time before (103 min vs 84 min, p < 0.001) and after propensity matching [regression coefficient (RC): 10.7 (8.87, 12.5)]. There was no increase in length of stay. There was an increased risk in mortality in the unadjusted analysis (prevalence ratio = 1.61, p = 0.02), but when propensity-matched analysis was done, there was no statistically significant difference between the two groups. Concerning bleeding or transfusion, there was no difference in bleeding or rates of transfusion (p= 0.22, p = 0.21). CONCLUSION: Liver biopsy at the time of MBS is safe. It adds operative time, but there is no increase in length of stay, bleeding complications, morbidity, or death.

Long Term Outcomes after Laparoscopic Assisted Trans-Gastric Endoscopic Retrograde Cholangiopancreatography.

BACKGROUND: The gastric bypass is a commonly performed bariatric procedure. The stomach is divided into a small pouch as well as leaving a larger remnant that is bypassed by the gastrojejunal anastomosis. This makes access to the biliary system difficult as an endoscope cannot transverse the esophagus, roux limb, and biliopancreatic limb. Therefore, a transgastric approach (endoscopic retrograde cholangiopancreatography [t-ERCP]) through the abdominal wall and remnant stomach is necessary. This involves the surgical team providing access to the remnant stomach for the gastroenterologist to perform the t-ERCP. We have performed a number of these for biliary pathology that ranges from cancer to retained gallstones. We evaluated these patients with at least a 3-year follow-up to determine long term outcomes. METHODS: We conducted a chart review of patients who underwent a t-ERCP with at least a 3-year follow-up. We collected de-identified data including demographics, operative details, complications, and postoperative courses. RESULTS: There were 12 patients who underwent t-ERCP. Eleven patients had at least a 3-year follow-up with a mean follow-up of 68.1 months (excluding one death from pancreatic cancer). The most common pathology was benign biliary stricture (n = 6), followed by retained gallstones (n = 4), with one pancreatic cancer, and one normal examination. Two patients still had epigastric pain at long term follow-up after 3 years. CONCLUSION: T-ERCP is safe and efficacious with good long-term results.

The additive impact of multiple psychosocial protective factors on selected health outcomes among older adults.

Our objective was to investigate the additive properties of five psychosocial protective factors: purpose-in-life, resilience, optimism, internal locus of control and social connections. Self-reported psychological (depression, stress) and physical (health status, functionality) health outcomes and measured healthcare utilization and expenditures were included. The study sample was identified from adults age ≥65 who completed a health survey during May-June 2019 (N = 3,577). Each of the five protective factors was dichotomized as high/low (1/0) and counted with equal weighting. The protective factors were additive such that significant improvements in psychological and physical health outcomes were evident across factor subgroups: as the number of factors increased, health outcomes improved. The magnitude of the improvements was greatest between 0 and 1 factor. In addition, a significant linear trend for reduced healthcare expenditures ($1,356 reduction per factor added) was evident. Interventions promoting at least one protective factor would be beneficial for older adult populations.

Older Adult Caregivers' Experiences in an Online, Interactive Mindfulness Intervention.

BACKGROUND: While today's older adults experience longevity, they often manage several chronic conditions and increasingly serve as informal caregivers for aging parents, children with life-long disabilities, and spouses. Older adult caregivers managing personal chronic illness often experience significant psychosocial hardships. OBJECTIVE: The primary purpose of this study was to explore the experiences of older adult caregivers in an online, interactive mindfulness intervention. METHODS: Self-reported older caregivers who participated in an online-based mindfulness program (n = 20) were recruited for semi-structured interviews. Participants were asked to provide feedback about any previous experience with mindfulness and/or meditation, hopes or goals held prior to the start of the program, desired expectations, motivation for joining, impressions of sessions, most beneficial topics, potential application of content, and any perceived effects. Participants' responses were analyzed using qualitative content analysis. RESULTS: Five themes emerged from the analysis: Managing the Comprehensive Effects of Caregiving, Openness to Meditation and Mindfulness, Course Engagement and Incremental Growth, Building Rapport through Shared Experiences, and Ongoing Application and Opportunities for Refinement. Participants reported both short-term post-exercise benefits such as increased calm, relaxation, and stress relief, as well as long-term positive outcomes. Notably, participants found the program's unique interactive feature to be particularly beneficial as a form of perceived social support. CONCLUSIONS: Caregivers for older adults may derive benefit and potentially experience reduced subjective caregiver burden as a result of participating in a Mindfulness-Based Stress Reduction (MBSR) program, particularly when the program is augmented with a self-compassion approach and perceived social support.

Robotic Pet Use Among Community-Dwelling Older Adults.

OBJECTIVE: The primary purpose of this study was to explore the efficacy of robotic pets in alleviating loneliness for older adults. METHOD: Self-reported lonely individuals with AARP Medicare Supplement plans insured by UnitedHealthcare who participated in a program with a robotic pet (n = 20) were recruited to participate in semi-structured interviews. Participants were asked to provide feedback about their experiences interacting with a robotic pet, their perceptions about the potential impact on loneliness, and recommendations for improving the program. Interviews were audio-recorded and transcribed verbatim. Participants' responses were analyzed using qualitative content analysis. Constant comparison and consensus-gaining processes were used to develop categories that later formed representative themes. RESULTS: Seven themes emerged from analysis: Openness to Adoption of Robotic Pet, Reactions to Pet and its Attributes, Integration of Pet in Daily Life, Strategic Utilization and Forging New Connections, Deriving Comfort and Camaraderie, Advice for Future Users, and Recommendations for Enhancing Ownership Experience. Participants living alone, with fewer social connections and less active lifestyles, derived the most benefit from interacting with their pets. Common responses to pets included cuddling, petting, grooming, and sleeping with them. Some shared or loaned their pets, while others refused to loan their pets to interested peers. Most reported showing their pets to others, which helped some facilitate communication and social connections. CONCLUSION: Robotic pets may be an effective solution for alleviating loneliness in older adults, especially among those who live alone, have fewer social connections, and live less active lifestyles.

The MBSAQIP is going viral! 194 hits and still going strong.

BACKGROUND: The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) first released its Participant Use Data File in 2015. Since then, surgeons have eagerly evaluated data now available on >750,000 patients, and a yearly increase in the number of publications using the Participant Use File was anticipated. OBJECTIVE: To evaluate the impact of the MBSAQIP in surgical literature. SETTING: University surgical department, United States. METHODS: A literature search was performed to identify articles published using the MBSAQIP database up to March 2019. PubMed, Clinical Key (both indexed for MEDLINE), and Cochrane databases were queried using the keywords "MBSAQIP" and "Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program." Abstracts presented at ObesityWeek, SAGES, and the Clinical Congress of the ACS in 2016 to 2019 were also examined. Duplicates, letters to the editor, commentaries, statements, and position pieces were excluded. Articles describing projects that used MBSAQIP data to study <5 accredited centers were also excluded. RESULTS: As of March 2019, there were 114 results in PubMed, 216 results in Clinical Key, and 0 in Cochrane using the search terms. Additionally, 184 abstracts were included from the journal supplements from ObesityWeek, SAGES, and the Clinical Congress of the ACS. After elimination of duplicates, there were 327 total results. After exclusions, 55 published manuscripts and 126 abstracts remained. CONCLUSION: The MBSAQIP is a resounding success. A substantial body of research has already been produced from it and is growing with time. Gaps in current knowledge are being targeted through analyses of this single, large-scale database. The MBSAQIP will remain a valuable leading resource in metabolic and bariatric surgery.

Small bowel obstructions following the use of barbed suture: a review of the literature and analysis of the MAUDE database.

BACKGROUND: Barbed suture has been adopted across all surgical specialties. One of the infrequent complications seen with the use of barbed suture is small bowel obstructions (SBOs). In this study, we perform a review of the literature and the Manufacturer and User Facility Device Experience Database (MAUDE) to characterize SBOs after the use of barbed sutures in a variety of operative procedures. METHODS: A review of the literature was performed by searching PubMed and Ovid. We used the search terms: "barbed," "suture," "bowel," and "obstructions." For each case report, we examined the initial surgical procedure, type of barbed suture used, the type of complication, the time to complication, the presentation, and the type of operative interventions required. We did the same with the MAUDE database. RESULTS: Our review of the literature revealed 18 different cases of SBO secondary to the use of barbed suture. The four most common procedures, with a total of four cases each, were inguinal hernia procedures, myomectomy, hysterectomy, and pelvic floor reconstructive procedures. The average time of presentation to SBO was found to be 26.3 days post-op (1-196 days). A total of 16 patients (88.9%) presented with abdominal pain. Other common complaints included vomiting (33.3%), abdominal distension (27.8%), oral intolerance (22.2%), and constipation (16.7%). A total of 5 cases were also found to have a possible volvulus on computed tomography (CT), and 2 cases were reported to have strangulation. The MAUDE database had 14 cases reporting on obstruction. CONCLUSIONS: Surgeons should have a high index of suspicion for SBO if a patient presents with obstructive symptoms after a surgery that used barbed suture. This will often present as a mesenteric volvulus on CT. These particular SBOs require operative exploration, with laparoscopy being successful in the majority of cases.

Trends in Drain Utilization in Bariatric Surgery: an Analysis of the MBSAQIP Database 2015-2017.

BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGB) and sleeve gastrectomy (SG) are the two most common bariatric operations. With the implementation of enhanced recovery protocols, the use of drains should decrease. METHODS: The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database was queried for the years 2015-2017. Our inclusion criteria included all patients undergoing a primary LRYGB, SG, and revisions. We examined demographics, operative characteristics, the use of drains, and postoperative complications. Continuous variables were summarized using means and standard deviations (SD). Categorical variables were summarized using frequencies and proportions. Student's T test (Wilcoxon sum rank test in the case of skewed data) and chi-squared analysis were used to assess the baseline differences in drain utilization. RESULTS: From 2015 to 2017, there were 388,239 bariatric cases performed without drains and 100,221 performed with drains. Twenty-nine percent of LRYGB patients had a drain placed but only 16.7% of SG patients. The percentage of LRYGB that had a drain dropped from 33.1 to 24.6% during the study period and that of SG dropped from 20.3 to 13.6%. Patients that had drains placed were more likely to have a provocative test at the time of surgery (prevalence ratio (PR) 2.24) and to have a postoperative swallow study (PR 1.93). CONCLUSIONS: Drains are still commonly used in bariatric patients. Over the study period, there was a decrease in the use of drains in both bypass and sleeve patients. Patients with a drain were more likely to have had a provocative test and a swallow study and have a higher rate of complications and mortality.

Where are sleeves performed? An analysis of inpatient versus outpatient databases in a large state.

BACKGROUND: The sleeve gastrectomy (SG) is the most common bariatric surgery in the United States today. There is a trend toward performing SG as an outpatient procedure, either in an ambulatory setting or as an outpatient at a larger hospital. The term "outpatient" is used to designate essentially any patient without an inpatient order. Texas maintains the Texas Inpatient Public Use Data File (IPUDF) database and the Texas Outpatient Public Use Data File (OPUDF) database for inpatient and outpatient settings, respectively. OBJECTIVES: To determine where SGs are performed by evaluating the Texas IPUDF and OPUDF for 2016. SETTING: University hospital, United States. METHODS: The Texas IPUDF and OPUDF were searched with the Current Procedural Terminology code of 43775 and the International Classification of Diseases, 10th revision, procedure code of 0DB64Z3. Patient demographic characteristics were also examined. We looked at the top 5 diagnoses in each database. RESULTS: Of the 16,855 SGs performed in Texas in 2016, outpatient SGs accounted for 31.0% (5227 cases), and inpatient SGs accounted for 69% of the total with 11,628 cases reported. For patients reported in the OPUDF, mean length of stay (LOS) was 2.1 (standard deviation 3.2) days with a median of 1.0 (interquartile range = 1, 2) days; for patients in the IPUDF, mean LOS was 1.6 (standard deviation 1.5) days, and the median was 1.0 (interquartile range = 1, 1) days. CONCLUSION: A third of SGs in Texas were performed under outpatient status. Further study is needed to determine the safety of this practice.

Characteristics of New-Onset and Chronic Sleep Medication Users Among Older Adults: A Retrospective Study of a US Medigap Plan Population using Propensity Score Matching.

BACKGROUND: Prescription sleep medications are often utilized to manage sleep problems among older adults even though these drugs are associated with multiple risks. OBJECTIVE: The aim was to determine the prevalence and characteristics of new-onset compared to chronic sleep medication users and to examine factors associated with the conversion from new to chronic use. A secondary objective was to investigate the impact of sleep medications on health outcomes of injurious falls and patterns of healthcare utilization and expenditures. METHODS: A 25% random sample of adults ≥ 65 years with 3-year continuous AARP® Medicare Supplement medical and AARP® MedicareRx drug plan enrollment was utilized to identify new-onset and chronic sleep medication users. Prescription sleep medication drugs were defined using National Drug Codes (NDCs); falls or hip fractures were identified from diagnosis codes. New users had no sleep medication use in 2014, but initiated medication use in 2015; chronic users had at least one sleep medication prescription in 2014 and in 2015; both groups had follow-up through 2016. Characteristics associated with new users, new users who converted to chronic use, and chronic users were determined using multivariate logistic regression. Prevalence of falls, healthcare utilization and expenditures were regression adjusted. RESULTS: Among eligible insureds, 3 and 9% were identified as new-onset and chronic sleep medication users, respectively. New-onset sleep medication prescriptions were often associated with an inpatient hospitalization. The strongest characteristics associated with new users, those who converted to chronic use, and chronic users were sleep disorders, depression and opioid use. About 50% of new users had > 30 days' supply; 25% converted to chronic use with ≥ 90 days' supply. The prevalence of falls for new-onset users increased by 70% compared to a 22% increase among chronic users. CONCLUSION: New-onset and chronic sleep medication users were characterized by sleep disorders, depression and pain. Addressing the underlying problems associated with sleep problems among older adults may decrease the need for sleep medications and thus reduce the risk of sleep medication-related adverse events.

Practical non-pharmacological intervention approaches for sleep problems among older adults.

Poor sleep is common among older adults, often caused by multiple underlying factors such as chronic stress. Poor sleep is subsequently associated with negative health outcomes including higher morbidity and mortality. Our primary purpose is to explore practical non-pharmacological intervention approaches integrating stress management to improve sleep quality among older adults. In doing so, we highlight approaches that appear to hold promise in real-world settings with older individuals. We conducted a tailored literature review specifically on approaches to improve sleep quality among older adults, with emphasis on those integrating stress management. Online search engines were reviewed to identify research in these areas. Various non-pharmacological intervention approaches, such as mindfulness and cognitive behavioral therapy, have shown promise in improving sleep quality and health outcomes within this population. Those integrating chronic stress management appear to be particularly successful. Thus further development of multidimensional sleep interventions integrating stress management with seniors is warranted.

The impact of mobility limitations on health outcomes among older adults.

The purpose of this study was to stratify an older adult population for subsequent interventions based on functional ability, and to estimate prevalence, characteristics and impact of mobility limitations on health outcomes. In 2016, surveys were sent to a stratified random sample of AARP® Medicare Supplement insureds; mobility limitations were defined using two screening questions. Responses were stratified to three mobility limitation levels. Multivariate regression models determined characteristics and impact on health outcomes. Among weighted survey respondents (N = 15,989), severe, moderate and no limitation levels were 21.4%, 18.4% and 60.3%, respectively. The strongest predictors of increased limitations included pain and poor health. Individuals with more severe limitations had increased falls, decreased preventive services compliance and increased healthcare utilization and expenditures. Utilizing two screening questions stratified this population to three meaningful mobility limitation levels. Higher levels of mobility limitations were strongly associated with negative health outcomes. Mobility-enhancing interventions could promote successful aging.

Purpose in Life and Positive Health Outcomes Among Older Adults.

Purpose in life (PIL) is conceptualized as having goals, a sense of direction, and a feeling that there is meaning to present and past life. PIL has been associated with positive health outcomes among older adults, including fewer chronic conditions, less disability, and reduced mortality. The purpose of this study was to estimate the prevalence of PIL among AARP Medicare Supplement insureds, identify associated characteristics, and measure impact on selected health outcomes. In 2016, surveys were sent to a random stratified sample; PIL was measured using a 7-item scale with 5 responses. Scores were averaged across responses and categorized to PIL levels of low, medium, and high. Survey responses were weighted to adjust for nonresponse bias and to weight to a nationally representative population. Multivariate regression models, adjusting for confounding covariates, were utilized to determine characteristics associated with PIL levels and the impact on health care utilization and expenditures, preventive services compliance and quality of life (QOL). Among weighted survey respondents (N = 15,680), low, medium, and high PIL levels were 24.2%, 21.1%, and 54.7%, respectively. The strongest characteristics of medium and high PIL included social support, resilience, reliance on faith, high health literacy, and good health status. Individuals with medium and high PIL had significantly lower health care utilization and expenditures, increased preventive services compliance, and higher QOL. PIL is strongly associated with improved mental and physical health outcomes among older adults. Thus, interventions to improve and/or maintain higher levels of PIL over time may promote successful aging.

A Pilot Online Mindfulness Intervention to Decrease Caregiver Burden and Improve Psychological Well-Being.

Interventions to reduce caregiver burden are of great interest as the number of informal family caregivers continues to grow. The purpose of this study was to test the feasibility of an online mindfulness meditation intervention for community-dwelling older adult caregivers and to evaluate its impact on quality of life, caregiver burden, and psychological well-being. A total of 40 caregivers were recruited from 2 community center support groups to participate in an 8-week online mindfulness intervention. Pre and post surveys were administered. Retention rates were high with 55% completing the post surveys and attending at least 5 out of 8 sessions. Matched pairs t test indicated that the intervention reduced caregiver burden, perceived stress, anxiety, and loneliness and improved mental well-being. Online interventions offer flexibility for caregivers regardless of their responsibilities. Future research should expand this opportunity and explore the scalability of online mindfulness interventions.

Falls-Related Drug Use and Risk of Falls Among Older Adults: A Study in a US Medicare Population.

BACKGROUND: Approximately one-third of community-dwelling older adults fall each year, and approximately 10% have falls requiring medical services. Among other factors, research studies have linked certain medications with an increased risk of falls. OBJECTIVE: The aim of this study was to examine the risk of falls relative to use patterns among new and continuing falls-related drug (FRD) users. METHODS: A 10% random sample, insured in AARP® Medicare Supplement and AARP Medicare Part D Rx plans, was utilized to define new and continuing FRD users. New users had a 12-month pre-period without FRD use, whereas continuing users had at least one FRD in the pre-period. Both groups had 12-month follow-up after initiating or continuing FRD use. Characteristics associated with the risk of falls for new and continuing users were determined using multivariate logistic regression models. RESULTS: Among insureds, 44% used at least one of the FRD classes. Of these, 29% were new users (N = 35,340) and 71% were continuing users (N = 121,488). Fall rates for the two subgroups were similar at 7 and 8%, respectively. Characteristics associated with the risk of falls were previous injurious fall, use of two or more classes of FRDs, older age, poorer health, and being female. New users were at higher risk than continuing users. CONCLUSION: New users of FRDs were at highest risk of falls, and continuing users were at increased risk, especially with higher numbers of FRD classes. Both groups could benefit from falls awareness and prevention programs.
