Physician and patient determinants of the treatment of sleep difficulties in U.S. outpatient settings

The prevalence of sleep difficulties among the patients seen in the primary care settings is about 30%. This problem increases with age and is more common among females than males. Variations are noticed in prescription choices for different patients with sleep difficulties. Many factors affect a physician's prescription decision while chosen from a wide array of available medications. Both pharmacological and behavioral therapies are available for the treatment of sleep difficulties. It is important to know the impact of use of different types of prescriptions on health outcomes related to sleep difficulties. Thus the knowledge of prescription patterns among different types of patients (e.g. age, gender, race, insurance type etc.) becomes important for determining a clinical guideline. This study is designed to assist in evidence-based policymaking on understanding the variations in physician prescriptions for sleep difficulties and reasons for such variations. ^ A modified version of the model suggested by Eisenberg was used as a theoretical framework for this study to predict the factors influencing treatment of sleep difficulties. Multivariate logistic regression methods were used to analyze the 1996–2001 National Ambulatory Medical Care Survey data. ^ This study found that increased age, female gender, white race, established patients, and mental comorbidity were associated with significantly increased likelihood for prescription of some type of therapy for sleep difficulties in US outpatient settings. Patients with private insurance were associated with lower likelihood of receipt of many therapies. Psychiatrists were more likely to prescribe some kind of treatment as well as more expensive therapies for sleep difficulty as compared to other physician specialties. HMO enrolled patient visits were more likely to be associated with receipt of behavioral therapy. This study also found that 32% of patients with sleep difficulties received no type of therapy during their visits. Only 5% of the patients received behavioral therapy only. Almost three-quarters of the patients receiving some kind of medication prescription were prescribed benzodiazepines. The study results also suggest a need for wider coverage of behavioral therapy by payers in US outpatient settings. ^

Juvenile onset central nervous system folate deficiency and rheumatoid arthritis.

Isolated cerebral folate deficiency was detected in a 13-year-old girl with cognitive and motor difficulties and juvenile rheumatoid arthritis. Her serum contains autoantibodies that block membrane-bound folate receptors that are on the choroid plexus and diminish the uptake of folate into the spinal fluid. Whereas her serum folate exceeded 21 ng/mL, her spinal fluid contained 3.2 ng/mL of 5-methyltetrahydrofolate as a consequence of the autoantibodies diminishing the uptake of this folate.

Family health history discussion in patient-provider encounters

Ascertaining the family health history (FHH) may provide insight into genetic and environmental susceptibilities specific to a variety of chronic diseases, including type II diabetes mellitus. However, discussion of FHH during patient-provider encounters has been limited and uncharacterized. A longitudinal, observational study was conducted in order to compare the content of FHH topics in a convenience sample of 37 patients, 13 new and 24 established. Each patient had an average of three follow-up encounters involving 6 staff physicians at the Audie L. Murphy Memorial Veterans Hospital (VHA) in San Antonio, TX from 2003 to 2005. A total of 131 encounters were analyzed in this study. The average age of the selected population was 68 years and included 35 males and two females. Transcriptions of encounters were obtained, coded and analyzed, in NVIVO 8. Of the 131 total encounters transcribed among the 37 patients, only 24 encounters (18.3%) included discussion of FHH. Additionally, the relationship between FHH discussion and discussion of self-care management (SCM) topics were assessed. In this study, providers were more likely to initiate discussion on family health history among new patients in the first encounter (ORnew = 8.55, 95% CI: 1.49–52.90). The discussion of FHH occurred sporadically in established patients throughout the longitudinal study with no apparent pattern. Provider-initiated FHH discussion most frequently had satisfactory level(s) of discussion while patient-initiated FHH discussion most frequently had minimal level(s) of discussion. FHH discussion most oftentimes involved topics of cancer and cardiovascular disease among primary-degree familial relationships. Overall, family health histories are largely, an underutilized tool in personalized preventive care.^
