Inadequate management of blood pressure in a hypertensive population.

BACKGROUND Many patients with hypertension have inadequate control of their blood pressure. Improving the treatment of hypertension requires an understanding of the ways in which physicians manage this condition and a means of assessing the efficacy of this care. METHODS We examined the care of 800 hypertensive men at five Department of Veterans Affairs sites in New England over a two-year period. Their mean (+/-SD) age was 65.5+/-9.1 years, and the average duration of hypertension was 12.6+/-5.3 years. We used recursive partitioning to assess the probability that antihypertensive therapy would be increased at a given clinic visit using several variables. We then used these predictions to define the intensity of treatment for each patient during the study period, and we examined the associations between the intensity of treatment and the degree of control of blood pressure. RESULTS Approximately 40 percent of the patients had a blood pressure of > or =160/90 mm Hg despite an average of more than six hypertension-related visits per year. Increases in therapy occurred during 6.7 percent of visits. Characteristics associated with an increase in antihypertensive therapy included increased levels of both systolic and diastolic blood pressure at that visit (but not previous visits), a previous change in therapy, the presence of coronary artery disease, and a scheduled visit. Patients who had more intensive therapy had significantly (P<0.01) better control of blood pressure. During the two-year period, systolic blood pressure declined by 6.3 mm Hg among patients with the most intensive treatment, but increased by 4.8 mm Hg among the patients with the least intensive treatment. CONCLUSIONS In a selected population of older men, blood pressure was poorly controlled in many. Those who received more intensive medical therapy had better control. Many physicians are not aggressive enough in their approach to hypertension.

Quality improvement implementation in the nursing home

OBJECTIVE To examine quality improvement (QI) implementation in nursing homes, its association with organizational culture, and its effects on pressure ulcer care. DATA SOURCES/STUDY SETTING Primary data were collected from staff at 35 nursing homes maintained by the Department of Veterans Affairs (VA) on measures related to QI implementation and organizational culture. These data were combined with information obtained from abstractions of medical records and analyses of an existing database. STUDY DESIGN A cross-sectional analysis of the association among the different measures was performed. DATA COLLECTION/EXTRACTION METHODS Completed surveys containing information on QI implementation, organizational culture, employee satisfaction, and perceived adoption of guidelines were obtained from 1,065 nursing home staff. Adherence to best practices related to pressure ulcer prevention was abstracted from medical records. Risk-adjusted rates of pressure ulcer development were calculated from an administrative database. PRINCIPAL FINDINGS Nursing homes differed significantly (p<.001) in their extent of QI implementation with scores on this 1 to 5 scale ranging from 2.98 to 4.08. Quality improvement implementation was greater in those nursing homes with an organizational culture that emphasizes innovation and teamwork. Employees of nursing homes with a greater degree of QI implementation were more satisfied with their jobs (a 1-point increase in QI score was associated with a 0.83 increase on the 5-point satisfaction scale, p<.001) and were more likely to report adoption of pressure ulcer clinical guidelines (a 1-point increase in QI score was associated with a 28 percent increase in number of staff reporting adoption, p<.001). No significant association was found, though, between QI implementation and either adherence to guideline recommendations as abstracted from records or the rate of pressure ulcer development. CONCLUSIONS Quality improvement implementation is most likely to be successful in those VA nursing homes with an underlying culture that promotes innovation. While QI implementation may result in staff who are more satisfied with their jobs and who believe they are providing better care, associations with improved care are uncertain.

Adherence to Pressure Ulcer Prevention Guidelines: Implications for Nursing Home Quality

OBJECTIVES: This study aims to assess overall nursing home (NH) implementation of pressure ulcer (PU) prevention guidelines and variation in implementation rates among a geographically diverse sample of NHs.

An exploration of job design in long-term care facilities and its effect on nursing employee satisfaction.

Abstract: This study used quantitative and qualitative methods to examine the design of nursing jobs in long-term care facilities and the effect of job design on employee satisfaction.

Clinical Practice Guidelines in the Nursing Home

Clinical practice guidelines are an important tool for improving quality of care. This study determined whether and how guidelines are being used in nursing homes. We surveyed staff at 36 Department of Veterans Affairs (VA) nursing homes. Employees were asked whether they were familiar with guidelines as well as whether 5 specific guidelines had been read, were available, and had been adopted. Among 1065 respondents (60% of those surveyed), 79% reported familiarity with guidelines. The proportion of staff at a facility reporting adoption was generally less than 50%. Those nursing homes in which a high percentage of the staff reported adoption of one guideline were more likely to have adopted other guidelines. However, staff were not more likely to report adoption of a specific guideline when the nurse manager stated that it was adopted. We conclude that staff at VA nursing homes are familiar with guidelines. Guideline adoption at individual nursing homes, however, is not a systematic process involving the entire staff.

Profiling outcomes of ambulatory care: casemix affects perceived performance

OBJECTIVES The authors explored the role of casemix adjustment when profiling outcomes of ambulatory care. METHODS The authors reviewed the medical records of 656 patients with hypertension, diabetes, or chronic obstructive pulmonary disease (COPD) receiving care at one of three Department of Veterans Affairs medical centers. Outcomes included measures of physiological control for hypertension and diabetes, and of exacerbations for COPD. Predictors of poor outcomes, including physical examination findings, symptoms, and comorbidities, were identified and entered into regression models. Observed minus expected performance was described for each site, both before and after casemix adjustment. RESULTS Risk-adjustment models were developed that were clinically plausible and had good performance properties. Differences existed among the three sites in the severity of the patients being cared for. For example, the percentage of patients expected to have poor blood pressure control were 35% at site 1, 37% at site 2, and 44% at site 3 (P < 0.01). Casemix-adjusted measures of performance were different from unadjusted measures. Sites that were outliers (P < 0.05) with one approach had observed performance no different from expected with another approach. CONCLUSIONS Casemix adjustment models can be developed for outpatient medical conditions. Sites differ in the severity of patients they treat, and adjusting for these differences can alter judgments of site performance. Casemix adjustment is necessary when profiling outpatient medical conditions.

Providing All-Inclusive Care for Frail Elderly Veterans : Evaluation of Three Models of Care

Frail elderly veterans aged 55 and older who met state nursing home admission criteria were enrolled in one of three models of all‐inclusive long‐term care (AIC) at three Veterans Affairs (VA) medical centers (n=386). The models included: VA as sole care provider, VA‐community partnership with a Program of All‐inclusive Care for the Elderly (PACE), and VA as care manager with care provided by PACE. Healthcare use was monitored for 6 months before and 6 to 36 months after enrollment using VA, DataPACE, and Medicare files. Hospital and outpatient care did not differ before and after AIC enrollment. Only 53% of VA sole‐provider patients used adult day health care (ADHC), whereas all other patients used ADHC. Nursing home days increased, but permanent institutionalization was low. Thirty percent of participants died; of those still enrolled in AIC, 92% remained in the community. VA successfully implemented three variations of AIC and was able to keep frail elderly veterans in the community. Further research on providing variations of AIC in general is warranted.

Problems in assessing diabetes control in an ambulatory setting

Problems in using medical records to assess outcomes of diabetes care have not been well defined. We reviewed the medical records of 288 patients with diabetes receiving ambulatory care over a 2-year period. We determined the availability of different tests of glycemic control and described site performance as the percent age of patients with a blood glucose exceeding either 180 or 240 mg/dl. Glycosylated hemoglobin determinations were performed in only 26.7% of patients. A blood glucose was available in 208 patients (72.2%) during a 6-month outcome period. For almost 50% of the sample, the glucose was greater than 180 mg/dl, whereas in 20% it exceeded 240 mg/dl. Judgments of whether sites dif fered in performance depended on how control was defined. Using a single glucose determination and a threshold of 180 mg/dl, similar fractions of patients were poorly controlled at each site (51.2 versus 45.0 versus 47.0%) (P = 0.75). At 240 mg/dl, although, one site per formed much worse than the other two (14.6 versus 16.7 versus 31.8%) ( P = 0.02). These results highlight diffi culties in defining the outcome measure when using med ical records to evaluate quality of care.
