Use of anxiolytics and hypnotic drugs.

Toward a more cautious approach, as per OBRA

All drugs prescribed for the nursing home patient may be considered to be psychoactive, in that they may affect the central nervous system (CNS) (Table 1). Nurses may ascribe most of these CNS effects to underlying disease processes rather than to these medications. That is why one of the most important assessments to be made by the charge nurse, with the consultant pharmacist's input, is whether a drug effect is involved. The question is, "How did this medicine affect the patient within the first several days to weeks after the drug was started?"

For example, the nursing home patient with dementia may reverse his or her sleep cycle and "sundown" (i.e. become more confused at the evening hours) and therefore have difficulty falling asleep at the usual hours. The preferred treatment for this sleep disorder is to involve the patient in physical activities as much as possible during the daytime, and to prevent napping, especially after meals. If a hypnotic medication is prescribed nightly, especially one of the longer-acting benzodiazepines (LABZs) - whether FDA-approved or not for sleep (e.g. only fluazepam, estazolam, temazepam, triazolam and quazepam are so-approved), the patient will usually experience normal sleep for several evenings, then after days to weeks start experiencing daytime carryover sedation and increased confusion. If continued, the LABZs also increase the risk of falls and fractures, especially in the Alzheimer's disease patient.

The OBRA guidelines for hypnotic usage in long-term care patients specify that LABZs not be used unless shorter-acting benzodiazepines (SABZs) have been tried. The OBRA guidelines further state that sleeping medications should not be used for more than 10 consecutive days in any 30-day period, nor should any benzodiazepine be used for longer than 3 to 4 months for anxiety disorders (Table 2). Even the SABZs given more often than three times a week increase the risk of falls in the frail elderly patient. If the caregiver notes any increased confusion, daytime sedation, or falls, the prescriber should be contacted.

SABZs should also be used for the agitation and harmful behavior associated with psychoses. The recommended drugs and doses for SABZ use in the Alzheimer's disease patient are shown in Table 2.

It is important for patient caregivers and prescribers to realize that the need for psychotropic medication diminishes as the patient advances through the stages of dementia. The continued usage of potent antipsychotics and LABZs in particular may in fact increase the overall rate of complications in the patient. The recommended dosage of any drug for the agitated demented patient is considerably less than the OBRA requirements, as may be noted in Table 3.

It should be noted that the OBRA regulations consider the usage of all barbiturates (except phenobarbital as an anticonvulsant) and non-barbiturate sedative hypnotics as "unnecessary drugs," and attempts should be made to gradually taper these drugs by no more than 10 to 15 percent of the daily dose per week. The same tapering recommendation should be made for the LABZs when used for more than one to two weeks on a daily basis, to prevent severe withdrawal symptoms of nervousness and cramps, as well as other vague pain complaints, insomnia, hallucinations, and agitation.

The appropriate usage of medications for anxiety and sleep disorders in the nursing home patient is the shared responsibility of the administrator, nurses, attending physicians and consultant and provider pharmacists. A routine assessment of the compliance with the OBRA guidelines for appropriate agents (e.g. SABZs before LABZs), dosage, and duration of therapy, as well as efficacy and toxicity, should be a part of the ongoing Quality Assurance and Assessment Committee's commitment to utilization review for each patient of every facility.
