ABSTRACT To estimate trends in the prevalence and comorbidities of diabetes mellitus (DM) in U.S. nursing homes from 1995 to 2004.
SAS callable SUDAAN was used to adjust for the complex sample design and assess changes in prevalence of DM and comorbidities during the study period in the National Nursing Home Surveys. Trends were assessed using weighted least squares linear regression. Multiple logistic regressions were used to calculate predictive margins.
A continuing series of two-stage, cross-sectional probability national sampling surveys.
Residents aged 55 and older: 1995 (n=7,722), 1997 (n=7,717), 1999 (n=7,809), and 2004 (n=12,786).
DM and its comorbidities identified using a standard set of diagnosis codes.
The estimated crude prevalence of DM increased from 16.9% in 1995 to 26.4% in 2004 in male nursing home residents and from 16.1% to 22.2% in female residents (all P<.05). Male and female residents aged 85 and older and those with high functional impairment showed a significant increasing trend in DM (all P<.05). In people with DM, multivariate-adjusted prevalence of cardiovascular disease increased from 59.6% to 75.4% for men and from 68.1% to 78.7% for women (all P<.05). Prevalence of most other comorbidities did not increase significantly.
The burden of DM in residents of U.S. nursing homes has increased since 1995. This could be due to increasing DM prevalence in the general population or to changes in the population that nursing homes serve. Nursing home care practices may need to change to meet residents' changing needs.

    ABSTRACT: Objective: There are limited data on combinations of co-morbid conditions to guide efforts to improve therapeutic strategies in patients with multiple co-morbid conditions. To some extent, this may be due to limited data on combinations of co-morbid conditions in patient groups. Our goal was to determine the most common co-morbid medical conditions in older residents of U. S. nursing homes and identify sex differences in prevalences and changes across the agespan of nursing residents. Design: Cross sectional analysis of National Nursing Home Survey (NNHS) -a nationally representative sample with comprehensive medical data on nursing home residents. Setting: 1174 Nursing homes. Participants: Long term stay residents of U.S. Nursing Homes aged 65 years and older (11,734 :8745 women, 2989 men). Measurements: Determination of the prevalences of the most frequent two and three disease combinations identified using Clinical Classifications Software (CCS) for ICD-9-CM and a composite vascular disease diagnosis (atherosclerosis and/or coronary artery disease, and/or peripheral arterial disease, and/or cerebrovascular disease or stroke) from the most recent and only NNHS survey with comprehensive medical diagnosis information. Results: Frequent 2-disease combinations were: hypertension (HTN) + dementia (DEM) in 27%, HTN + any Vascular (Vasc) disease (26%), HTN + depression(DEP) 21%, HTN + arthritis(ARTH) 20%, DEM + Vasc (21%), DEM+Depression 19%, Arthritis + DEM 17%, DEP + Vasc (16%), ARTH + Vasc (15%), followed by HTN + GERD (14%) and ARTH + DEP (14%). Frequent 3-disease combinations: HTN +VASC+ DEP in 13%, HTN +DEM +DEP (11%), and HTN+Arthritis+DEM (10%). HTN was in 80% of the top 3-disease combinations, Vasc in 50%, HTN+VASC in 35%, DEM or DEP in 40%, ARTH in 25% and GERD in 20%. Combinations with anemia, arthritis, dementia, heart failure, osteroporosis, thyroid disease were higher in women, COPD combinations higher in men. As age increased, dementia, depression, arthritis, and anemia with hypertension were common co-morbid combinations, diabetes and heart failure were not. Conclusions: Hypertension, vascular disease, dementia, arthritis, depression, and gastro-esophageal reflux disease were part of the most prevalent co-morbid conditions. Multimorbidity patterns can be identified in nursing home residents and vary with age and by sex.

    ABSTRACT: Aims Determine prevalence of diabetes, and describe use of blood glucose lowering (BGL) drugs and glycemic control in Norwegian nursing homes. Methods In this cross-sectional study we collected details of BGL drugs, capillary blood glucose measurements (CBGM) in the last four weeks and HbA1c measurements in the last 12 months from the medical records of patients with diabetes, within a population of 742 long-term care patients from 19 randomly selected nursing homes in Western Norway. Descriptive statistics were applied, and Pearson's chi-squared (P≤0.05) or non-overlapping 95% confidence intervals were interpreted as significant effects. Results 116 patients (16%) had diabetes, 100 of these gave informed consent and medical data were available. BGL treatment was a s follows 1) insulin only (32%), 2) insulin and oral antidiabetics (OADs) (15%), 3) OADs only (27%) and 4) no drugs (26%). Patients with cognitive impairment were less likely to receive medical treatment (P = 0.04). CBGM and HbA1c measurements were performed for 73% and 77% of patients, respectively. Mean HbA1c was 7.3% (57 mmol/mol), 46% of patients had an HbA1c <7.0% (53 mmol/mol), and CBGM consistent with risk of hypoglycemia was found for 60% of these patients. Conclusions Prevalence of diabetes and BGL treatment in Norwegian nursing homes is comparable to other European countries. Although special care seems to be taken when choosing treatment for patients with cognitive impairment, there are signs of overtreatment in the population as a whole. The strict glycemic control unveiled may negatively affect these frail patients’ quality of life and increase the risk of early death.
