Predicting Mortality in Nursing Home Residents With Dementia and Pneumonia Treated With Antibiotics: Validation of a Prediction Model in a More Recent Population

Item does not contain fulltextBACKGROUND: We aimed to find the best predictive model for 14-day mortality in antibiotic-treated nursing home residents with dementia and pneumonia by first applying an existing model to the recent PneuMonitor study. Second, we evaluated whether model performance improved by revising variables or adding variables related to recent changes in the care for older people. METHODS: The original prognostic model included gender, respiratory rate, respiratory difficulty, pulse rate, decreased alertness, fluid intake, eating dependency, and pressure sores. This model was applied to 380 recent pneumonia episodes in nursing home residents with dementia, updated by considering revising and/or adding variables, internally validated using bootstrapping, and transformed into a simplified risk score that can be used in clinical practice. Model performance was evaluated by Hosmer-Lemeshow statistics and calibration graphs to assess calibration; and area under the receiver operating characteristic curve (AUC) to assess discrimination. RESULTS: The newer cohort had lower 14-day mortality and was less often dehydrated or malnourished. Median AUC of the original model over the imputed datasets was 0.76 (interquartile range: 0.76-0.77), compared to 0.80 in the old cohort. Extending the model with dehydration, bowel incontinence, increase in eating dependency and cardiovascular history, while removing pressure sores, improved AUC: 0.80 (interquartile range: 0.80-0.81) after internal validation. Calibration remained adequate (Hosmer-Lemeshow statistic: p = .67). CONCLUSIONS: In the newer cohort with less severe illness, model performance of the existing model was adequate, but a new extended model distinguished better between residents at low and high mortality risk

Improving comfort in people with dementia and pneumonia: a cluster randomized trial

BACKGROUND: Pneumonia in people with dementia has been associated with severe discomfort. We sought to assess the effectiveness of a practice guideline for optimal symptom relief for nursing home residents with dementia and pneumonia. METHODS: A single-blind, multicenter, cluster randomized controlled trial was conducted in 32 Dutch nursing homes. Outcomes were assessed on the patient level. The main outcome measures were discomfort and symptoms: discomfort (DS-DAT: Discomfort Scale-Dementia of Alzheimer Type), (lack of) comfort (EOLD-CAD: End Of Life in Dementia-Comfort Assessment in Dying), pain (PAINAD: Pain Assessment in Advanced Dementia), and respiratory distress (RDOS: Respiratory Distress Observation Scale). Outcomes were scheduled daily from diagnosis until 10 days later and a final time between 13-15 days from diagnosis by trained observers who were blinded to the intervention and the residents' condition and treatment. In a pre-intervention phase, usual care was provided to all homes. In the intervention phase, matched clusters of homes were randomized to either the control (n = 16) or intervention condition (n = 16). RESULTS: Between 1 January 2012 and 1 May 2015, 464 episodes of pneumonia were included. Outcomes were obtained for 399 episodes in 367 residents. Longitudinal multilevel linear regression analyses were performed on log-transformed outcomes, so coefficients should be interpreted as a ratio, and a coefficient of 1 means no difference. The practice guideline in the intervention phase did not reduce the level of discomfort and symptoms: DS-DAT: 1.11 (95 % CI 0.93-1.31), EOLD-CAD: 1.01 (95 % CI 0.98-1.05), PAINAD: 1.04 (95 % CI 0.93-1.15), RDOS: 1.11 (95 % CI 0.90-1.24). However, in both the intervention and control groups, lack of comfort and respiratory distress gradually decreased during the entire 3.5 years of data collection, and were lower in the intervention phase compared to the pre-intervention phase: DS-DAT: 0.93 (95 % CI 0.85-1.01), EOLD-CAD: 0.98 (95 % CI 0.97-1.00), PAINAD: 0.96 (95 % CI 0.91-1.01), RDOS: 0.92 (95 % CI 0.87-0.98). CONCLUSIONS: When compared to usual care, the practice guideline for optimal symptom relief did not relieve discomfort and symptoms in nursing home residents with dementia and pneumonia. However, discomfort and symptoms decreased gradually throughout the data collection in both the intervention homes and the control homes. An intervention that focuses on creating awareness may be more effective than a physician practice guideline. TRIAL REGISTRATION: The Netherlands National Trial Register (ID number NTR5071 .

Development of a practice guideline for optimal symptom relief for patients with pneumonia and dementia in nursing homes using a Delphi study

Item does not contain fulltextOBJECTIVE: This study aimed to develop a practice guideline for a structured and consensus-based approach to relieve symptoms of pneumonia in patients with dementia in nursing homes. METHODS: A five-round Delphi study involving a panel consisting of 24 experts was conducted. An initial version of the practice guideline was developed with leading representatives of Dutch University Medical Centers with a department for elderly care medicine, based on existing guidelines for palliative care. The experts evaluated the initial version, after which we identified topics that reflected the main divergences. The experts rated their agreement with statements that addressed the main divergences on a 5-point Likert scale. Consensus was determined according to pre-defined criteria. The practice guideline was then revised according to the final decisions made by the project group and the representatives. RESULTS: The response rate for the expert panel was 67%. Main divergences included the applicability of guidelines for palliative care to patients with dementia and pneumonia in long-term care and the appropriateness of specific pharmacological treatment of dyspnea and coughing. Moderate consensus was reached for 80% of the statements. Major revisions included adding pharmacological treatment for coughing and recommending opioid rotation in the case of opioid-induced delirium. Two areas of divergent opinion remained: the usefulness of oxygen administration and treatment of rattling breath. The project group made the final decision in these areas. CONCLUSIONS: We developed a mostly consensus-based practice guideline for patients with dementia and pneumonia and mapped controversial issues for future investigation
