Predictive validity of the BRASS index in screening patients with post-discharge problems. Blaylock Risk Assessment Screening Score.

RATIONALE: Discharge planning is a nursing intervention that aims to ensure continuity of care; it consists of several steps of which selecting patients in need of it is the first one. The Blaylock Risk Assessment Screening Score (BRASS) index is a risk screening instrument which can be used early after admission to identify those patients in need of discharge planning. AIM: To test the predictive validity of the BRASS index in screening patients with post-discharge problems. DESIGN: Prospective longitudinal design with prediction instrument measured at admission, and outcomes measured at discharge and 7 and 30 days after discharge. OUTCOME MEASURES: length of stay, discharge destination, status after discharge. INSTRUMENTS: BRASS index, Problems after discharge Questionnaire, Nottingham Health Profile, COOP/WONCA charts. RESEARCH METHOD: 503 elderly patients were screened at admission with the BRASS index. Length of stay and discharge destination were measured at discharge in these same patients. Outcomes after discharge were gathered only in patients who were discharged home and with length of stay of more than 3 days (n=226); outcomes were measured by postal questionnaires at day 7 and day 30 after discharge. RESULTS: patients identified by the BRASS index as high risk are frequently not discharged home and have a longer length of stay. The BRASS scores correlate significantly with the outcome scores after discharge: the higher the BRASS score, the higher the difficulty score after discharge on all domains. However, the sensitivity of the BRASS index is rather low. CONCLUSION: This study demonstrates that the BRASS index is a good predictor instrument for indicating patients who are not discharged home, that the BRASS scores correlate significantly with problems experienced after discharge and that it has high specificity to predict patients with problems after discharge. Clinical use, however, is limited due to the low sensitivity. The BRASS index is a promising case-finding instrument for discharge planning, but needs further development.

Enantiomeric resolution using the macrocyclic antibiotics rifamycin B and rifamycin SV as chiral selectors for capillary electrophoresis.

Rifamycin B and rifamycin SV belong to the class of macrocyclic antibiotics known as ansamycins. These macrocyclic antibiotics were used as chiral selectors in capillary electrophoresis to enantioselectively resolve a number of chiral compounds. They contain groups capable of providing the types of multiple interactions necessary to achieve chiral recognition between enantiomers. In fact, they appear to be complimentary in the types of compounds they can enantiomerically resolve. Rifamycin B is shown to be enantioselective towards positively charged compounds, while rifamycin SV was enantioselective towards negatively charged solutes. The choice of wavelength for detection significantly affects sensitivity. Monitoring one of the wavelengths which coincide with the absorption minima of the chiral selector enhances sensitivity. Resolution is enhanced by keeping the amount of analyte injected on column as low as possible and it is demonstrated that it is possible to detect as little as 0.1% of one enantiomer in the presence of the other enantiomer using indirect detection.

Discharge planning predicting patients' needs.

The elderly are at higher risk for longer and more frequent lengths of hospital stay than other adults. Comprehensive discharge planning programs, including early identification of those at risk, can alter these statistics. Screening inventories to identify patients at risk have been available for many years, but they are not specific to the needs of the elderly. The Blaylock Risk Assessment Screen (BRASS) is administered on admission and identifies patients at risk for prolonged hospital stay and in need of discharge planning resources. The nurse can use the data BRASS provides to improve care outcomes while the patient is in the hospital and in the transition to home care. It shows promise for use as the first phase of a discharge planning program.
