High-Dose Monthly Vitamin D for Prevention of Acute Respiratory Infection in Older Long-Term Care Residents: A Randomized Clinical Trial.

ABSTRACT: OBJECTIVES:To determine the efficacy and safety of high-dose vitamin D supplementation for prevention of acute respiratory infection (ARI) in older long-term care residents. DESIGN:Randomized controlled trial investigating high-dose vs standard-dose vitamin D from 2010 to 2014. SETTING:Colorado long-term care facilities. PARTICIPANTS:Long-term care residents aged 60 and older (n = 107). INTERVENTION:The high-dose group received monthly supplement of vitamin D3 100,000 IU, the standard-dose group received a monthly placebo (for participants taking 400-1,000 IU/d as part of usual care) or a monthly supplement of 12,000 IU of vitamin D3 (for participants taking <400 IU/d as part of usual care). MEASUREMENTS:The primary outcome was incidence of ARI during the 12-month intervention. Secondary outcomes were falls and fractures, 25-hydroxyvitamin D levels, hypercalcemia, and kidney stones. RESULTS:Participants (55 high dose, 52 standard dose) were randomized and included in the final analysis. The high-dose group had 0.67 ARIs per person-year and the standard-dose group had 1.11 (incidence rate ratio (IRR) = 0.60, 95% confidence interval (CI) = 0.38-0.94, P = .02). Falls were more common in the high-dose group (1.47 per person-year vs 0.63 in standard-dose group; IRR = 2.33, 95% CI = 1.49-3.63, P < .001). Fractures were uncommon and similar in both groups (high dose 0.10 vs standard dose 0.19 per person-year; P = .31). Mean trough 25-hydroxyvitamin D levels during the trial were 32. ng/mL in the high-dose group and 25.1 ng/mL in the standard-dose group. There was no hypercalcemia or kidney stones in either group. CONCLUSION:Monthly high-dose vitamin D3 supplementation reduced the incidence of ARI in older long-term care residents but was associated with a higher rate of falls without an increase in fractures.

Project description:ImportanceOlder adults residing in long-term care facilities (LTCFs) are at a high risk of being infected with respiratory viruses, such as influenza and respiratory syncytial virus (RSV). Although these infections commonly have many cardiorespiratory sequelae, the national burden of influenza- and RSV-attributable cardiorespiratory events remains unknown for the multimorbid and vulnerable LTCF population.ObjectiveTo estimate the incidence of cardiorespiratory hospitalizations that were attributable to influenza and RSV among LTCF residents and to quantify the economic burden of these hospitalizations on the US health care system by estimating their associated cost and length of stay.Design, setting, and participantsThis retrospective cohort study used national Medicare Provider Analysis and Review inpatient claims and Minimum Data Set clinical assessments for 6 respiratory seasons (2011-2017). Long-stay residents of LTCFs were identified as those living in the facility for at least 100 days (index date), aged 65 years or older, and with 6 months of continuous enrollment in Medicare Part A were included. Follow-up occurred from the resident's index date until the first hospitalization, discharge from the LTCF, disenrollment from Medicare, death, or the end of the study. Residents could re-enter the sample; thus, long-stay episodes of care were identified. Data analysis was performed between January 1 and September 30, 2020.ExposuresSeasonal circulating pandemic 2009 influenza A(H1N1), human influenza A(H3N2), influenza B, and RSV.Main outcomes and measuresCardiorespiratory hospitalizations (eg, asthma exacerbation, heart failure) were identified using primary diagnosis codes. Influenza- and RSV-attributable cardiorespiratory events were estimated using a negative binomial regression model adjusted for weekly circulating influenza and RSV testing data. Length of stay and costs of influenza- and RSV-attributable events were then estimated.ResultsThe study population comprised 2 909 106 LTCF residents with 3 138 962 long-stay episodes and 5 079 872 person-years of follow-up. Overall, 10 939 (95% CI, 9413-12 464) influenza- and RSV-attributable cardiorespiratory events occurred, with an incidence of 215 (95% CI, 185-245) events per 100 000 person-years. The cost of influenza- and RSV-attributable cardiorespiratory events was $91 055 393 (95% CI, $77 885 316-$104 225 470), and the length of stay was 56 858 (95% CI, 48 757-64 968) days.Conclusions and relevanceThis study found that many cardiorespiratory hospitalizations among LTCF residents in the US were attributable to seasonal influenza and RSV. To minimize the burden these events place on the health care system and residents of LTCFs and to prevent virus transmission, additional preventive measures should be implemented.

Project description:ImportanceThe Centers for Medicare & Medicaid Services' (CMS) National Partnership to Improve Dementia Care in Nursing Homes ("CMS National Partnership") focuses on reducing antipsychotic prescribing to long-term care residents. Hospice enrollment is not an exclusionary condition for the antipsychotic quality measure reported by CMS. It is unclear how prescribing in hospice may have been impacted by the initiative.ObjectiveEstimate the association of the CMS National Partnership with trends in antipsychotic prescribing among long-term care residents in hospice.DesignInterrupted time-series analysis of a 100% Minimum Data Set sample with linked hospice claims from 2011 to 2017.SettingLong-term care nursing facilities.ParticipantsOlder adults ≥65 residing in long-term care (n = 3,741,379) and limited to those enrolled in hospice (n = 821,610).Main outcomeQuarterly prevalence of antipsychotic and other psychotropic (antianxiety, hypnotic, antidepressant) use among long-term care residents; overall and among residents with dementia, stratified by hospice enrollment.ResultsFrom 2011 to 2017, parallel declines in antipsychotic prescribing were observed among long-term care residents enrolled and not enrolled in hospice (hospice: decline from 26.8% to 18.7%; non-hospice: decline from 23.0% to 14.4%). Following the 2012 CMS National Partnership, quarterly rates of antipsychotic prescribing declined significantly for both residents enrolled and not enrolled in hospice care. Declines in antipsychotic prescribing were greater for residents with dementia, with similar rates among residents enrolled and not enrolled in hospice. Among residents with dementia enrolled in hospice, use of other psychotropic medication classes including antianxiety, antidepressant, and hypnotic use remained relatively stable over time.Conclusions and relevanceDeclines in antipsychotic prescribing during the CMS National Partnership occurred among long-term care residents in hospice, where use may be deemed clinically appropriate. Nursing homes are an important location for the provision of dementia end-of-life care and the drivers of potentially unintended reductions in antipsychotic use merits further investigation.

Project description:BACKGROUND:Respiratory infections among older adults in long-term care facilities (LTCFs) are a major global concern, yet a rigorous systematic synthesis of the literature on the burden of respiratory infections in the LTCF setting is lacking. To address the critical need for evidence regarding the global burden of respiratory infections in LTCFs, we assessed the burden of respiratory infections in LTCFs through a systematic review of the published literature. METHODS:We identified articles published between April 1964 and March 2019 through searches of PubMed (MEDLINE), EMBASE, and the Cochrane Library. Experimental and observational studies published in English that included adults aged ?60 residing in LTCFs who were unvaccinated (to identify the natural infection burden), and that reported measures of occurrence for influenza, respiratory syncytial virus (RSV), or pneumonia were included. Disagreements about article inclusion were discussed and articles were included based on consensus. Data on study design, population, and findings were extracted from each article. Findings were synthesized qualitatively. RESULTS:A total of 1451 articles were screened for eligibility, 345 were selected for full-text review, and 26 were included. Study population mean ages ranged from 70.8 to 90.1?years. Three (12%) studies reported influenza estimates, 7 (27%) RSV, and 16 (62%) pneumonia. Eighteen (69%) studies reported incidence estimates, 7 (27%) prevalence estimates, and 1 (4%) both. Seven (27%) studies reported outbreaks. Respiratory infection incidence estimates ranged from 1.1 to 85.2% and prevalence estimates ranging from 1.4 to 55.8%. Influenza incidences ranged from 5.9 to 85.2%. RSV incidence proportions ranged from 1.1 to 13.5%. Pneumonia prevalence proportions ranged from 1.4 to 55.8% while incidence proportions ranged from 4.8 to 41.2%. CONCLUSIONS:The reported incidence and prevalence estimates of respiratory infections among older LTCF residents varied widely between published studies. The wide range of estimates offers little useful guidance for decision-making to decrease respiratory infection burden. Large, well-designed epidemiologic studies are therefore still necessary to credibly quantify the burden of respiratory infections among older adults in LTCFs, which will ultimately help inform future surveillance and intervention efforts.
