Use of proton-pump inhibitors and their associated risks among frail elderly nursing home residents.

OBJECTIVE: The aim of this study is to investigate the use of proton-pump inhibitors (PPI) and their associated risks among frail elderly nursing home residents. DESIGN: A cross-sectional study. SETTING: General practice. SUBJECTS: An assessment of residents (n = 1987, mean age 83.7 years) in all nursing homes in Helsinki was carried out in February 2003. Data included demographic characteristics, symptoms such as diarrhea, vomiting and constipation, use of various drugs, and medical diagnoses. OUTCOME: Coded data analysis with NCSS statistical program. Multivariate logistic regression analysis served to determine which variables were independently associated with diarrhea; variables which were statistically significant or near p < 0.05 in univariate analyses were included. RESULTS: Altogether 433 residents were on PPIs. The factors associated with regular PPI use in univariate analyses included poor functional status, higher number of comorbidities, higher number of medications and lactose intolerance. The users had suffered from a prior ventricular or duodenal ulcer, cancer and coronary heart disease more often than the non-users. In accordance with our hypothesis, the users of PPIs more often had diarrhea (19.7%) than the non-users (12.9%) (p < 0.001), and they had a prior hip fracture (28.5%) more often than the non-users (19.4%) (p < 0.001). In logistic regression analysis the use of PPIs had an independent association with diarrhea (OR 1.60 (95% CI 1.20 to 2.15). CONCLUSION: Physicians should avoid unnecessary long-term use of PPIs, particularly among frail elderly long-term care patients.

Exposure to potentially inappropriate drugs and drug-drug interactions in elderly nursing home residents in Helsinki, Finland: a cross-sectional study.

BACKGROUND AND OBJECTIVE: Multiple drug use is common among old, frail nursing home residents who are, as a consequence, susceptible to adverse effects and drug interactions. This study uses the updated Beers criteria for potentially inappropriate drug (PID) use in older adults to determine the extent and nature of PIDs in older nursing home residents in Helsinki, Finland. The study also uses the Swedish, Finnish, INteraction X-referencing (SFINX) interaction database to assess the possibility of clinically significant class D ("clinically significant interaction, and the combination should be avoided") drug-drug interactions (DDIs) in the same population. METHODS: This study is a cross-sectional assessment of all nursing home residents aged > or = 65 years in Helsinki. The residents' demographic information and medical data were collected from medical charts in February 2003. RESULTS: Of all nursing home residents in Helsinki, 82% (n = 1987) were eligible for analysis. Their mean age was 83.7 (SD 7.7) years, 80.7% were female and 69.5% were diagnosed with dementia. The mean number of drugs given on a regular basis per resident was 7.9 (SD 3.6) per day. Of the study population, 34.9% regularly used at least one PID. Residents taking PIDs were more likely to be taking psychotropic medication and to be taking nine or more drugs daily, and less likely to have a diagnosis of dementia, than patients not taking PIDs. The three most prevalent PIDs were: (i) short-acting benzodiazepines in greater than recommended doses (13.9% of all residents), of which temazepam >15 mg/day was the most commonly used agent and, indeed, the most common PID (taken by 13.5% of all residents); (ii) hydroxyzine (7.1%); and (iii) nitrofurantoin (6.3%). Together, these three PIDs accounted for 76.9% of all PID use. Of all residents, 4.8% were susceptible to a clinically significant DDI. The most common potential DDIs were related to the use of potassium-sparing diuretics, carbamazepine and codeine. Compared with residents not exposed to potential DDIs, residents exposed to potential DDIs were more likely to be younger, to have a prior history of stroke, to be taking psychotropics, to be taking nine or more drugs daily and to be taking PIDs. CONCLUSION: Use of PIDs is very common among nursing home residents, and this increases the likelihood of DDIs. Monitoring patients for PID use and potential drug interactions could increase the quality of prescribing.

Use of laxatives among older nursing home residents in Helsinki, Finland.

BACKGROUND AND OBJECTIVE: Constipation and, as a consequence, the use of laxatives are common among frail older people. The causes of and factors associated with laxative use, however, have undergone surprisingly little study. The objectives of our study were to (i) assess the prevalence of regularly administered laxatives, (ii) identify factors associated with regular use of laxatives, and (iii) determine which drug classes or medications are associated with regular laxative use in an older nursing home population in Helsinki. METHODS: This study was a cross-sectional assessment of all long-term nursing home residents aged >/=65 years in Helsinki, Finland. In February 2003, the health status of these residents was assessed and data on their demographic characteristics, health and medication use were collected from medical charts. RESULTS: Of all nursing home residents in Helsinki, 82% (n = 1987, mean age 83.7 years) participated in the study. Of all residents, 55.3% received laxatives regularly. Factors associated with regular laxative use in univariate analysis included age >80 years, stroke, Parkinson's disease, inability to move independently, poor Mini Nutritional Assessment (MNA) score (<17), fluid intake less than five glasses per day, and chewing problems. Drugs associated with laxative use included opioids, antacids, diuretics, tricyclic antidepressants, lipid-lowering drugs other than HMG-CoA reductase inhibitors (statins), histamine H(2) receptor antagonists, nonselective NSAIDs, anticholinergic drugs for urine incontinence, and calcium channel antagonists other than verapamil and nifedipine. In logistic regression analysis, age >80 years (odds ratio [OR] 1.29; 95% CI 1.03, 1.60), inability to move independently (OR 1.80; 95% CI 1.42, 2.28), poor MNA score (<17) [OR 1.51; 95% CI 1.19, 1.93], chewing problems (OR 1.27; CI 95% 1.00, 1.61), Parkinson's disease (OR 1.63; 95% CI 1.01, 2.64), and concomitant use of a high number (>7) of drugs other than laxatives and constipation-inducing drugs found in univariate analysis (OR 1.06; 95% CI 1.03, 1.09) were associated with use of laxatives. Having snacks between meals (OR 0.74; 95% CI 0.60, 0.90) was associated with lower risk of laxative use. CONCLUSIONS: Regular laxative use in older nursing home residents in Helsinki is very common. Offering snacks between meals and regular evaluation of medication use may influence laxative use.

Use of psychotropic drugs in elderly nursing home residents with and without dementia in Helsinki, Finland.

OBJECTIVE: Use of psychotropic medication is very common in nursing home residents. Our objective was to describe the use of psychotropic drugs in all long-term nursing home residents > or =65 years of age with and without dementia in Helsinki, Finland. METHOD: The study was a cross-sectional assessment of the nursing home population. The residents' health status was assessed and data on their demographic factors, health and medication use were collected from medical charts in February 2003. RESULTS: Of all nursing home residents in Helsinki, 82% (n = 1987) participated in the study. The nursing home residents' mean age was 83.7 (SD 7.7) years, 80.7% were female, and 69.5% were diagnosed with dementia. The mean number of drugs [corrected] given regularly was 7.9 (SD 3.6) per day per resident[corrected] Of the participants, 79.7% were regularly taking psychotropic medication. Conventional antipsychotics were administered to 18.9% of residents and atypical antipsychotics to 27.0%. Of the residents, 26.7% were on selective serotonin reuptake inhibitors (SSRIs), 3.1% on tricyclic antidepressants and 17.6% on other antidepressants. Altogether, 44.6% of residents were taking one or more antidepressant. More than a quarter (26.3%) were taking at least one anxiolytic drug. Hypnotics were used by 27.5%. However, only moderate dosages of psychotropic drugs were being taken. Only 10.4% of individuals with dementia were regularly taking cholinesterase inhibitors and four residents were taking memantine. CONCLUSIONS: Use of psychotropic drugs is very common in nursing homes in Helsinki, Finland, with four of five nursing home residents regularly receiving psychotropic drugs. Only one in ten residents were receiving cholinesterase inhibitors. Physicians caring for nursing home residents require further education on the benefits and adverse effects of psychotropic drugs in frail elderly people.
