The Relationship of Antipsychotic Drug Use, Resident Behavior, and Diagnoses Among Nursing Home Residents

Nursing homes have been criticized for frequent use and possible misuse of psycho-active agents. These issues are of clinical concern and policy relevance, especially since the passage of the Omnibus Budget Reconciliation Act (OBRA) of 1987. Using a sample of 419 residents, the authors examined the relationships among antipsychotic drug (AP) use, behavior, and mental health diagnoses. Only 23.2% of the residents were administered APs on a routine and/or "as-needed" basis. Based on the Multidimensional Observation Scale for Elderly Subjects (MOSES) ratings, AP users were more irritable, disoriented, and withdrawn than were nonusers. Also, AP users demonstrated agitated behaviors more frequently. Notably, AP users and nonusers differed significantly in terms of documented mental health diagnoses. Among AP users, 70.1% had documented dementia, 8.3% were psychotic or had other psychiatric disorders, and 21.6% had no mental health diagnoses. In contrast, the majority of nonusers had no mental health disorders. Logistic regression revealed that diagnostic factors, frequency of agitation, level of withdrawal, and marital status were significant predictors of AP use.

Service Use and Mental Impairment Among the Elderly: Arguments for Consultation and Education

Compared the service use patterns of older adults with varying levels of mental impairment, and assessed the effects of services received on their mental health status over a 1-yr period. Data were obtained from a US General Accounting Office (1977, 1979) study of 531 elderly persons (mean age 76.1 yrs), which included administration of a modified version of the Older Americans Resources and Services Multidimensional Functional Assessment Questionnaire. Ss were interviewed twice, 1 yr apart. 174 Ss were classified as having a mild psychiatric impairment, and 118 Ss had a severe psychiatric impairment. The existence of mental impairment was related to marital status, race, and level of education. Usage of mental health services was low, although mentally impaired Ss were more likely than unimpaired Ss to use social and medical services. Results also suggest that such services can have an important effect on the mental health of older persons.

Correlation of Pullout Force of Kirschner (K-) Wire to Other Factors Indicative of Bone Quality

More than 250,000 hip fractures occur annually in the United States and the most common fracture location is the femoral neck, the weakest region of the femur. Hip fixation surgery is conducted to repair hip fractures by using a Kirschner (K-) wire as a temporary guide for permanent bone screws. Variation has been observed in the force required to extract the K-wire from the femoral head during surgery. It is hypothesized that a relationship exists between the K-wire pullout force and the bone quality at the site of extraction. Currently, bone mineral density (BMD) is used as a predictor for bone quality and strength. However, BMD characterizes the entire skeletal system and does not account for localized bone quality and factors such as lifestyle, nutrition, and drug use. A patient’s BMD may not accurately describe the quality of bone at the site of fracture. This study aims to investigate a correlation between the force required to extract a K-wire from femoral head specimens and the quality of bone. A procedure to measure K-wire pullout force was developed and tested with pig femoral head specimens. The procedure was implemented on 8 human osteoarthritic femoral head specimens and the average pullout force for each ranged from 563.32 ± 240.38 N to 1041.01 ± 346.84 N. The data exhibited significant variation within and between each specimen and no statistically significant relationships were determined between pullout force and patient age, weight, height, BMI, inorganic to organic matter ratio, and BMD. A new testing fixture was designed and manufactured to merge the clinical and research environments by enabling the physician to extract the K-wire from each bone specimen himself. The new device allows the physician to gather tactile feedback on the relative ease of extraction while load history is recorded similar to the previous procedure for data acquisition. Future work will include testing human bones with the new device to further investigate correlations for predicting bone quality.
