Age and sex variation in prevalence of chronic medical conditions in older residents of U.S. nursing homes.

ABSTRACT: To investigate patterns in prevalences of chronic medical conditions over the age span of long-term stay nursing home residents and between the sexes with data from the 2004 National Nursing Home Survey (NNHS).Retrospective, cross-sectional study.U.S. nursing homes.Nationally representative sample comprising 11,788 long-term stay residents (3,003 (25%) men, 8,785 (75%) women) aged 65 and older.Clinical Classifications Software was used to group International Classification of Diseases, Ninth Revision, codes to identify the 20 most-prevalent chronic medical conditions. SAS survey procedures were used to account for design effects of stratification and clustering to generate nationally representative estimates of prevalences of medical conditions.Average age was 84, with women older than men (85 vs 81, P = .02) and 67% of women aged 80 to 95. Women required more assistance with activities of daily living. The most frequent chronic medical conditions were hypertension (men 53%, women 56%), dementia (men 45%, women 52%), depression (men 31%, women 37%), arthritis (men 26%, women 35%), diabetes mellitus (men 26%, women 23%), gastroesophageal reflux disease (GERD) (men 23%, women 23%), atherosclerosis (men 24%, women 20%), congestive heart failure (CHF) (men 18%, women 21%), cerebrovascular disease (CVD) (men 24%, women 19%), and anemia (men 17%, women 20%). Sex differences in prevalences existed for all but constipation, GERD, and hypertension. Diabetes mellitus, CVD, and lipid disorders decreased with age in men and women. Atrial fibrillation, anemia, arthritis, CHF, dementia, and thyroid disease increased with age in men and women. Age-related patterns differed between the sexes for diabetes mellitus, hypertension, and Parkinson's disease.The profile of chronic medical conditions varies over the age span of nursing home residents and differs between men and women. This knowledge should guide educational and care efforts in long-term care.

Project description:ObjectivesEstimates of influenza vaccine use are not available at the county level for U.S. nursing home (NH) residents but are critically necessary to guide the implementation of quality improvement programs aimed at increasing vaccination. Furthermore, estimates that account for differences in resident characteristics between counties are unavailable. We estimated risk-standardized vaccination rates (RSVRs) among short- and long-stay NH residents by U.S. county and identified drivers of geographic variation.MethodsWe conducted a retrospective cohort study utilizing 100% of 2013-2015 fee-for-service Medicare claims, Minimum Data Set assessments, Certification and Survey Provider Enhanced Reports, and Long-Term Care: Facts on Care in the U.S. We separately evaluated short-stay (<100 days) and long-stay (≥100 days) residents aged 65 and older across the 2013-2014 and 2014-2015 influenza seasons. We estimated RSVRs via hierarchical logistic regression adjusting for 32 resident-level covariates. We then used multivariable linear regression models to assess associations between county-level NHs predictors and RSVRs.ResultsThe study cohort consisted of 2,817,217 residents in 14,658 NHs across 2798 counties. Short-stay residents had lower RSVRs than long-stay residents (2013-2014: median [interquartile range], 69.6% [62.8-74.5] vs 84.0% [80.8-86.4]), and there was wide variation within each population (range, 11.4-89.8 vs 49.1-92.6). Several modifiable facility-level characteristics were associated with increased RSVRs, including higher registered nurse to total nurse ratio and higher total staffing for licensed practical nurses, speech-language pathologists, and social workers. Characteristics associated with lower RSVRs included higher percentage of residents restrained, with a pressure ulcer, and NH-level hospitalizations per resident-year.ConclusionsSubstantial county-level variation in influenza vaccine use exists among short- and long-stay NH residents. Quality improvement interventions to improve vaccination rates can leverage these results to target NHs located in counties with lower risk-standardized vaccine use.

Project description:Residents in nursing homes (NHs) always represent potential reservoirs for Staphylococcus aureus and methicillin-resistant S. aureus (MRSA). To our knowledge, there is no epidemiological information up till now that describes the prevalence and molecular characteristics of S. aureus in nursing home residents in Shanghai, China.Four hundred and ninety-one unique residents from 7 NHs were enrolled in this study. Specimens were collected among these residents including 491 nasal swabs, 487 axillary swabs and 119 skin swabs. S. aureus isolated and identified from the swabs was characterized according to antimicrobial susceptibility profiling, toxin gene prevalence, and multilocus sequence typing (MLST), spa and SCCmec typing.Among the 491 residents screened, S. aureus was isolated in 109 residents from 90 nasal swabs (90/491, 18.3%), 29 axillary swabs (29/487, 6.0%), and 22 skin swabs (22/119, 18.5%). Sixty-eight MRSA isolates were detected in 52 residents from 41 nasal carriers, 15 axillary carriers and 12 skin carriers. The overall prevalence rate of S. aureus and MRSA colonization was 22.2% and 10.6% respectively. Ten residents presented S. aureus in all three sample types and 12 residents presented S. aureus in two of the three sample types collected. Molecular analysis revealed CC1 (29.1%) to be the dominant clone in this study, followed by CC398 (19.9%), CC188 (13.5%) and CC5 (12.8%). The most common spa type was t127 (22.0%), followed by t14383 (12.8%) and t002 (10.6%).A high prevalence of S. aureus and MRSA colonization was revealed in nursing home residents in Shanghai. CC1 was the most common clonal complex and t127 was the most common spa type among NH residents. The data provides an important baseline for future surveillance of S. aureus in NHs in Shanghai and other highly urbanized regions in China. Implementation of infection control strategies must be given high priority in NHs to fight such high prevalence of both MRSA and methicillin-susceptible S. aureus (MSSA).
