Palliative care for nursing home patients with dementia: service evaluation and risk factors of mortality.

BACKGROUND: Difficulties in prognostication are common deterrents to palliative care among dementia patients. This study aimed to evaluate the effectiveness of palliative care in reducing the extent of utilization of medical services and the potential risk factors of mortality among dementia patients receiving palliative care. METHODS: We surveyed dementia patients involved in a palliative care program at a long-term care facility in Taipei, Taiwan. We enrolled 57 patients with advanced dementia (clinical dementia rating ≥ 5 or functional assessment staging test stage 7b). We then compared the extent of their utilization of medical services before and after the provision of palliative care. Based on multivariable logistic regression, we identified potential risk factors before and after the provision of palliative care associated with 6-month mortality. RESULTS: The utilization of medical services was significantly lower among dementia patients after the provision of palliative care than before, including visits to medical departments (p < 0.001), medications prescribed (p < 0.001), frequency of hospitalization (p < 0.001), and visits to the emergency room (p < 0.001). Moreover, patients dying within 6 months after the palliative care program had a slightly but not significantly higher number of admissions before receiving hospice care (p = 0.058) on univariate analysis. However, no significant differences were observed in multivariate analysis. CONCLUSIONS: The provision of palliative care to dementia patients reduces the extent of utilization of medical services. However, further studies with larger patient cohorts are required to stratify the potential risk factors of mortality in this patient group.

Early treatment response predicted subsequent clinical response in patients with schizophrenia taking paliperidone extended-release.

This 6-week open-labeled study investigated whether early treatment response in patients receiving paliperidone extended-release (paliperidone ER) can facilitate prediction of responses at Week 6. Patients with schizophrenia or schizoaffective disorder were administered 9mg/day of paliperidone ER during the first 2 weeks, after which the dose was adjusted clinically. They were assessed on Days 0, 4, 7, 14, 28, and 42 by the Positive and Negative Syndrome Scale (PANSS). The serum concentrations of 9-hydroxyrisperidone were examined on Days 14 and 42. Among the 41 patients enrolled, 26 were classified as responders (≧50% improvement on total PANSS scores at Week 6). In the receiver-operator curves (ROC) analyses, the changes in total PANSS scores at Week 2 appeared to show more accurate predictability compared to Day 4 and Day 7. At Week 6, no significant correlation was observed between blood 9-hydroxyrisperidone concentration and the total score or changes of PANSS scores. The results suggest that early treatment response to paliperidone ER, particularly at Week 2, can serve as a suitable outcome predictor at Week 6. Using 9mg/day paliperidone ER as an initial dose for schizophrenia treatment exhibited relatively favorable tolerability and feasibility.

Prevalence and identification of alcohol use disorders among severe mental illness inpatients in Taiwan.

AIMS: A higher prevalence of alcohol use disorders (AUD) among psychiatric patients has been reported previously and the identification rate is relatively low. This study was designed to investigate the prevalence and identification of AUD among acute psychiatric inpatients with severe mental illness in a psychiatric hospital in Taiwan. METHODS: In a two-phase case identification strategy, the Alcohol Use Disorders Identification Test (AUDIT) was used as the first phase screening tool and the Structured Clinical Interview for DSM-IV-TR as the second phase diagnostic interview. The definition of identification was diagnosis of AUD on medical record at discharge. RESULTS: Of 400 respondents, 42 screened positive and 358 screened negative. All screen-positive respondents and 35 screen-negative respondents entered the second phase interview. The weighted lifetime prevalence of alcohol dependence was 8.3% (95% confidence interval [CI]: 4.6-11.9%); alcohol abuse, 1.5% (95%CI: 0.2-2.8%); and AUD, 9.8% (95%CI: 5.7-13.8%). The overall identification rate of AUD by medical staff was 28.2% (0% for alcohol abuse and 33.3% for alcohol dependence). Patients with mood disorders were prone to being undetected as having AUD. CONCLUSION: AUD comorbidity was common among inpatients with severe mental illness in Taiwan and was easily neglected by medical staff. It is necessary to use a validated screening questionnaire, such as AUDIT, to detect high-risk patients and then give appropriate interventions to enhance treatment outcome.
