Xerostomia and polypharmacy among dependent older New Zealanders: a national survey.

BACKGROUND: Medication-induced xerostomia is common in older people. We investigated medication use and xerostomia in dependent older New Zealanders. METHODS: Medication and xerostomia data analysed from a nationally representative survey of dependent older people. Automatic interaction detection analysis identified medications combinations most strongly associated with xerostomia, and then xerostomia was modelled. RESULTS: Just over half were taking five to nine different medications; one in five was taking 10+. Xerostomia prevalence (29.4%; 95% confidence interval 26.5, 32.5) was higher among the latter and lowest in psychogeriatric patients. After controlling for age and sex, it was higher among people taking any antidepressant, and higher still with a tricyclic antidepressant and either a steroid or an anticholinergic, or among people taking a bronchodilator without prophylactic aspirin. CONCLUSIONS: Health practitioners should work together to ensure that those with xerostomia are managed in a timely and appropriate manner. Medication review is an important component of that.

Dentition and nutritional status of aged New Zealanders living in aged residential care.

BACKGROUND: Previous studies of the nutritional status of older individuals have used measures such as plasma vitamin and mineral levels, which can be difficult to interpret. The relationship between nutrition and dentition has been limited to studying exposures such as the number of posterior occluding pairs of teeth, edentulousness, and the number of natural teeth. OBJECTIVES: To investigate the association between dentition status and nutritional status in a national survey of older New Zealanders living in aged residential care facilities. MATERIAL AND METHODS: Secondary analysis of clinical oral status and nutrition data collected in 2012 in New Zealand's Older People's Oral Health Survey. The validated Mini Nutritional Assessment short format was used to categorize participants as "normal nutritional status," "at risk of malnutrition" or "malnourished." RESULTS: Just under half of older New Zealanders living in aged residential care facilities were classified as either at risk of malnutrition or malnourished (with about one in sixteen in the latter category). The prevalence of malnutrition was higher among those in hospital-level and psychogeriatric-level care, as well as in those of high socioeconomic status. Individuals who were at risk of malnutrition had the most untreated dental caries and untreated coronal caries. Relative to their counterparts in nursing-home-level care, dentate individuals in hospital-level care were 2.4 times-and those in psychogeriatric-level care were 2.8 times-as likely to be malnourished or at risk of it. CONCLUSIONS: Just under half of the New Zealanders living in aged residential care were at risk of malnutrition or were malnourished. Greater experience of untreated dental caries was associated with a higher rate of being malnourished or at risk of it. Poorer cognitive function and greater dependency were important risk indicators for malnutrition.

Oral status, cognitive function and dependency among New Zealand nursing home residents.

OBJECTIVES: To investigate clinical oral disease and its association with cognitive function and dependency among older New Zealanders in residential aged care. MATERIAL AND METHODS: National survey of oral health in aged residential care throughout New Zealand. We classified residents into 1 of 3 levels of care: "low dependency care (or assisted living)"; "high dependency care"; or "specialist dementia care/psychogeriatric care." The Abbreviated Mental Test characterised cognitive function as "unimpaired" (scores of 7-10), "moderately impaired" (4-6) or "severely impaired" (0-3). Intra-oral examinations were conducted, along with a computer-assisted personal interview. RESULTS: Most of the 987 clinically examined participants were either at low or high dependency care level, with another 1 in 6 in psychogeriatric care. Almost half overall had severely impaired cognitive function. Just under half of the sample had 1 or more natural teeth remaining. Negative binomial regression modelling showed that the number of carious teeth was lower among women and higher among those who were older, those with more teeth and in those with severely impaired cognitive function. Oral debris scores (representing plaque biofilm and other soft deposits on teeth) were higher in men, those with more teeth, and in those with severely impaired cognitive function. CONCLUSIONS: Impaired cognitive function is a risk indicator for both dental caries and oral debris in aged residential care.

The Challenge of Medication-Induced Dry Mouth in Residential Aged Care.

With a reported prevalence between 20% and 30%, dry mouth is more common among older people than any other age group. The major risk factor for dry mouth is polypharmacy. Older people take more medications than any other age group, not only for symptomatic relief of various age-associated chronic diseases, but also to reduce the likelihood of the complications that may arise from those conditions. Most aged care residents take even more medications than older people who are living in their own homes. The greater the number of medications taken, the greater the associated anticholinergic burden, and the more likely it is that the individual will suffer from dry mouth. The condition not only affects the dentition and ability to wear dentures, but also the sufferers' quality of life. Treating dry mouth is a considerable challenge for clinicians. As medication use is by far the most important risk factor, there is a need for pharmacists, doctors and dentists to work together to prevent this from occurring. Medication review and deprescribing is a key strategy, but there have not yet been any randomised control trials of its efficacy in reducing the occurrence of dry mouth.

Patient and clinician views on an app for rheumatoid arthritis disease monitoring: Function, implementation and implications.

AIM: Best practice management for rheumatoid arthritis (RA) involves regular clinical assessment of RA disease activity. This is not achievable with current rheumatology systems of care. We aimed to use opinions from people with RA and their specialist rheumatology healthcare professionals to inform development of a mobile app for people with RA for recording their disease activity data for potential integration into clinical service, and assess usability of the app. METHOD: In phase 1 we interviewed nine people with RA and seven healthcare professionals. In phase 2 we developed an app with professional software developers. In phase 3 we evaluated app usability for people with RA using the System Usability Scale (SUS). RESULTS: Interview data showed four themes regarding functionality and implementation of a patient-held app in RA care: (a) variable app acceptance and readiness; (b) app use to reduce barriers; (c) pros and cons of patient-reported outcomes; and (d) allocation of clinics by need. The app developed has high usability in people with RA using the app on their own device for a month (SUS 79.5, n = 16) or using the app on a study device for 10 minutes (SUS 83, n = 100). CONCLUSION: People with RA and healthcare professionals have clearly identified features, benefits and risks of an app for self-assessment of RA and incorporation into clinical care. An app developed informed by these opinions has high usability. Next steps are development and validation of a method of patient-performed joint counts, and implementation, with evaluation, in the clinical setting.
