Nursing home care quality: a multidimensional theoretical model

This exploratory study was undertaken to discover the defining dimensions of nursing home care quality and to propose a conceptual model to guide nursing home quality research and the development of instruments to measure nursing home care quality. Three focus groups were conducted in three central Missouri communities. A naturalistic inductive analysis of the transcribed content was completed. Two core variables (interaction and odor) and several related concepts emerged from the data. Using the core variables, related concepts, and detailed descriptions from participants, three models of nursing home care quality emerged from the analysis: (1) a model of a nursing home with good quality care; (2) a model of a nursing home with poor quality care; and (3) a multidimensional model of nursing home care quality. The seven dimensions of the multidimensional model of nursing home care quality are: central focus, interaction, milieu, environment, individualized care, staff, and safety. To pursue quality, the many dimensions must be of primary concern to nursing homes. We are testing an instrument based on the model to observe and score the dimensions of nursing home care quality.

Verifying nursing home care quality using minimum data set quality indicators and other quality measures

Researchers, providers and government agencies have devoted time and resources to the development of a set of Quality Indicators derived from Minimum Data Set (MDS) data. Little effort has been directed toward verifying that Quality Indicators derived from MDS data accurately measure nursing home quality. Researchers at the University of Missouri-Columbia have independently verified the accuracy of QI derived from MDS data using four different methods; 1) structured participative observation, 2) QI Observation Scoring Instrument, 3) Independent Observable Indicators of Quality Instrument, and 4) survey citations. Our team was able to determine that QIs derived from MDS data did differentiate nursing homes of good quality from those of poorer quality.

Efficacy and safety of a new protocol for continuous infusion of midazolam and fentanyl and its effects on patient distress during electrophysiological studies

Electrophysiological studies are often distressing for patients. We devised a regime of continuous infusion of midazolam and fentanyl during electrophysiological studies without the presence of a specialist anaesthetist. The effects on key hemodynamic and respiratory variables and level of sedation were evaluated in detail in the first 775 patients. The safety of this practice was evaluated in 1,344 consecutive patients. Doses were calculated according to patients' weight and age. A mean total dose of 26 mg of midazolam and 115 mcg of fentanyl were infused. Satisfactory sedation was achieved in 97% of patients. The mean duration of procedure was 188 +/- 90 minutes. Complete amnesia of the procedure was obtained in 87% of patients. Sedation caused clinically insignificant changes in respiratory rate, oxygen saturation, end-tidal CO2 and blood pressure. There were no major complications related to sedation. Upper airway obstruction, usually minor, occurred in 42% and some restlessness in 20% of sedated patients. The assistance of a specialist anesthetist was required in 0.3% of sedated patients for management of restlessness, hypoventilation, or obstructive sleep apnea. The amount of distress experienced by sedated patients (n = 775) was significantly less compared to a previous series of nonsedated patients (n = 775) undergoing electrophysiological studies (P < 0.001). The degree of distress experienced by patients during electrophysiological studies can be reduced significantly by sedation with intravenous midazolam and fentanyl. Continuous infusion is an efficient, safe, and effective way of administering midazolam and fentanyl.

Setting thresholds for MDS (Minimum Data Set) quality indicators for nursing home quality improvement reports

BACKGROUND

Determining meaningful thresholds to reinforce excellent performance and flag potential problem areas is critical for quality improvement reports. Without thresholds, an organization may interpret its performance as superior to others because it is "better than average" and falsely assume it does not have care problems in certain areas.

SETTING THRESHOLDS

The Minimum Data Set (MDS) assessment instrument is mandated for use nationwide in all nursing homes participating in Medicaid or Medicare programs. Since 1993 a research team at the University of Missouri-Columbia has been developing and testing quality indicators (QIs) derived from MDS data as a foundation for quality improvement activities. In July 1996, a cross-section of 13 clinical care personnel from nursing homes participated on an expert panel for threshold setting for QIs derived from MDS assessment data. Panel members individually determined good and poor threshold scores for each QI, reviewed statewide distributions of MDS QIs, and, two weeks later, completed a follow-up Delphi round. Three members of the research team reviewed the results of the expert panel and set the final thresholds. With thresholds established for good and poor scores, MDS QI scores are reported to a sample of Missouri nursing homes using the thresholds.

CONCLUSIONS

To ensure that thresholds reflect current practice, threshold setting with another panel of experts will be repeated as needed, but at least biannually. The report format will be revised on the basis of user input, and a statewide study testing different educational support methods for quality improvement using MDS QIs is now underway.

Out of balance: consequences of a partial keratin 10 knockout

Recently we generated keratin 10 knockout mice which provided a valuable model for the dominantly inherited skin disorder epidermolytic hyperkeratosis. Here we investigated the molecular basis for their phenotype. Hetero- and homozygotes expressed a truncated keratin 10 peptide which has been identified directly by microsequencing. Epitope mapping of monoclonal antibodies to keratin 10T enabled us to study its distribution relative to keratin 6, which is highly expressed in keratin 10 knockout mice, by double-immunogold electron microscopy. This revealed that keratin 10T was restricted to complexes with keratin 1 but did not mix with keratin 6. The latter did not form extended filaments with keratins 16/17 but aggregates. Keratins 6/16 were unable to compensate for the lack of normal keratin 1/10 filaments. Remarkably keratin 6 aggregates strictly colocalized with keratohyalin granules. Residual keratin 1/10T clumps were located in the cell periphery and at desmosomes which maintained a normal architecture. Surprisingly keratin 2e, a keratin tailored to sustain mechanical stress, was completely lost in paw sole epidermis of homozygous keratin 10 knockout mice, pointing to keratin 10 as its partner. The selective pairing of keratin 10T and the loss of keratin 2e indicate that in vivo keratins are less promiscuous than in vitro. Skin fragility in keratin 10 knockout mice and in epidermolytic hyperkeratosis is probably the consequence of two complementing mechanisms namely a decrease of normal keratin 1/10 filaments and an increase in keratins 6/16 with a poor filament-forming capacity.

Introducing external cephalic version at 36 weeks or more in a district general hospital: a review and an audit

OBJECTIVE

To audit the effect of introducing external cephalic version at > or = 36 weeks on breech delivery rates and modes, and to assess factors that affect external cephalic version success rates.

DESIGN

A prospective unblinded study over 12 months of factors affecting external cephalic version success. A retrospective review of breech deliveries for 12 months before introducing external cephalic version and the first 12 months of practising external cephalic versions.

SETTING

Royal United Hospital, Bath.

POPULATION

One hundred and three women (> or = 36 weeks) with breech presentation booked for external cephalic version, and 324 women with a singleton breech presentation at delivery between November 1992 and October 1994.

METHODS

External cephalic version attempted on 89 women. Tocolysis was used on 41 of these women.

MAIN OUTCOME MEASURES

External cephalic version success rate. Breech presentation rates (suitable for external cephalic version) at delivery. Delivery mode rates for breeches.

RESULTS

External cephalic version was successful in 39% of women. The breech presentation rate (external cephalic version suitable) at delivery fell from 2.7% to 2.4% of all deliveries. The vaginal breech delivery rate fell from 0.98% to 0.51%. The caesarean section rate was 63% for breeches (external cephalic version suitable) before external cephalic version introduction, and 47% among women who had an attempted external cephalic version.

CONCLUSIONS

Attempted external cephalic version reduces the woman's risk of vaginal breech delivery and caesarean section. It provides individual women with a third management option and the possibility of avoiding a vaginal breech delivery or a caesarean section. To avoid one caesarean section takes 5.9 attempted external cephalic versions. This approach is expensive in operator time. Operator, placental site, position of fetal back and amniotic fluid index had a significant effect on the success of external cephalic version.

Assessing contributors to cost of care in nursing homes

In 1994 12.7% of the population was 65 and over, while 10.6% were 85 and over. Expenditures for nursing homes reached $72.3 billion in 1994 (much of which is tax-supported) accounting for 8.7% of all personal health money spent. Data from the 1993 Missouri Medicaid cost reports for 403 nursing homes were reviewed to determine differences in costs per resident day (PRD) and discover which factors most influenced these differences. Mid-sized facilities with 60-120 beds reported the lowest resident-related PRD costs. PRD expenses for aides and orderlies were higher in tax-exempt facilities, which was thought to be related to their "more altruistic" mission. Investor-owned facilities showed significantly greater administrative costs PRD, which may relate to higher administrative salaries and fancier offices. The authors suggest further study that would incorporate location, occupancy rate, quality of care, case mix, and payer mix data.
