Physician, nurse, and social worker collaboration in primary care for chronically ill seniors.

OBJECTIVES: To examine the impact of an interdisciplinary, collaborative practice intervention involving a primary care physician, a nurse, and a social worker for community-dwelling seniors with chronic illnesses. METHODS: A concurrent, controlled cohort study of 543 patients in 18 private office practices of primary care physicians was conducted. The intervention group received care from their primary care physician working with a registered nurse and a social worker, while the control group received care as usual from their primary care physician. The outcome measures included changes in number of hospital admissions, readmissions, office visits, emergency department visits, skilled nursing facility admissions, home care visits, and changes in patient self-rated physical, emotional, and social functioning. RESULTS: From 1992 (baseline year) to 1993, the two groups did not differ in service use or in self-reported health status. From 1993 to 1994, the hospitalization rate of the control group increased from 0.34 to 0.52, while the rate in the intervention group stayed at baseline (P= .03). The proportion of intervention patients with readmissions decreased from 6% to 4%, while the rate in the control group increased from 4% to 9% (P=.03). In the intervention group, mean office visits to all physicians fell by 1.5 visits compared with a 0.5-visit increase for the control group (P=.003). The patients in the intervention group reported an increase in social activities compared with the control group's decrease (P=.04). With fewer hospital admissions, average per-patient savings for 1994 were estimated at $90, inclusive of the intervention's cost but exclusive of savings from fewer office visits. CONCLUSIONS: This model of primary care collaborative practice shows potential for reducing utilization and maintaining health status for seniors with chronic illnesses. Future work should explore the specific benefit accruing from physician involvement in the collaborative practice team.

Hospitalization rates in nursing home residents with dementia. A pilot study of the impact of a special care unit.

Although Special Care Units (SCUs) have recently gained attention as appropriate places for caring for institutionalized patients with dementia, few studies have evaluated their effectiveness. This pilot study focused primarily on one aspect of patient care, the possible prevention of acute hospitalization. Because transfer from nursing home to the acute hospital can be a traumatic experience for patients with dementia, important services that SCUs might provide include those preventive strategies aimed at reducing the need for transfer to the acute hospital. Medical record abstraction revealed that over one year, the rate of acute hospitalization was 21% among 47 patients with dementia in SCUs, compared with 14% among 36 patients with dementia and 14% among 22 patients with no listed diagnosis of dementia residing in non-SCU settings within the same facility. Thus, no statistically significant difference in hospitalization rates was found, although the trend was for increased hospitalization for SCU patients. There was a trend toward deterioration in functional status among SCU patients following first hospitalization (P less than .10). Since the majority of these patients were hospitalized for hip fractures, this finding was not unexpected. There was a trend toward cognitive decline after hospitalization among patients with dementia who were not residing in an SCU (P less than .10). In order to investigate whether acute hospitalizations among SCU patients were preventable, an expert panel was convened to review each episode of illness leading to acute hospitalization. Of the 15 hospitalizations, none were judged "preventable," four were believed to be "possibly preventable," and 11 were considered to have been "not preventable."(ABSTRACT TRUNCATED AT 250 WORDS)

Factors contributing to dehydration in nursing homes: inadequate staffing and lack of professional supervision.

OBJECTIVE: To investigate the factors that influenced fluid intake among nursing home residents who were not eating well. DESIGN: A prospective, descriptive, anthropological study. SETTING: Two proprietary nursing homes with 105 and 138 beds, respectively. PARTICIPANTS: Forty nursing home residents. MEASUREMENTS: Participant observation, event analysis, bedside dysphagia screening, mental and functional status evaluation, assessment of level of family/advocate involvement, and chart review were used to collect data. Data were gathered on the amount of liquid served and consumed over a 3- day period. Daily fluid intake was compared with three established standards: Standard 1 (30 mL/kg body weight), Standard 2 (1 mL/kcal/energy consumed), and Standard 3 (100 mL/kg for the first 10 kg, 50 mL/kg for the next 10 kg, 15 mL/kg for the remaining kg). RESULTS: The residents' mean fluid intake was inadequate; 39 of the 40 residents consumed less than 1500 mL/day. Using three established standards, we found that the fluid intake was inadequate for nearly all of the residents. The amount of fluid consumed with and between meals was low. Some residents took no fluids for extended periods of time, which resulted in their fluid intake being erratic and inadequate even when it was resumed. Clinical (undiagnosed dysphagia, cognitive and functional impairment, lack of pain management), sociocultural (lack of social support, inability to speak English, and lack of attention to individual beverage preferences), and institutional factors (an inadequate number of knowledgeable staff and lack of supervision of certified nursing assistants by professional staff) contributed to low fluid intake. During the data collection, 25 of the 40 residents had illnesses/conditions that may have been related to dehydration. CONCLUSIONS: When staffing is inadequate and supervision is poor, residents with moderate to severe dysphagia, severe cognitive and functional impairment, aphasia or inability to speak English, and a lack of family or friends to assist them at mealtime are at great risk for dehydration. Adequate fluid intake can be achieved by simple interventions such as offering residents preferred liquids systematically and by having an adequate number of supervised staff help them to drink while properly positioned.

A prospective study of the use of liquid oral dietary supplements in nursing homes.

OBJECTIVE: To investigate the use of liquid oral dietary supplements among nursing home residents who were eating poorly and losing weight. DESIGN: A prospective, descriptive, anthropological study. SETTING: Two proprietary nursing homes with 105 and 138 beds. PARTICIPANTS: Purposive sampling was used to select 40 residents from among the 100 residents who were not eating well. Dietary data were collected on this sub-sample of 40 residents. MEASUREMENTS: Participant observation, in-depth interviews, event analysis, bedside dysphagia screenings, oral health examinations, body weight, body mass index (BMI), and chart review were used to collect data. Dietary data were collected over a 3-day period, and data were gathered on how supplements were ordered, served, and consumed. RESULTS: Supplements had been ordered for 29 of the subsample of 40 residents. Only nine of 29 residents were served the correct number and type of supplements as ordered by their physicians, and only two residents consumed the full amount of supplement as ordered. The overall mean percentage of supplement consumed compared with that ordered was 55.1%. Although supplements were ordered primarily to prevent weight loss and to facilitate weight gain, nearly half (n = 14) of the residents continued to lose weight. Supplements were ordered without investigating the underlying factors contributing to weight loss, such as inadequate staffing and lack of supervision at mealtime, undiagnosed dysphagia, and poor oral health. Without evaluation of these factors, it is unknown which residents might benefit from oral supplements. CONCLUSION: Findings indicate that supplements were used nonspecifically as an intervention for weight loss in nursing home residents without regard to dose, diagnosis and management of underlying problem(s), amount of supplement consumed, and outcome. Further research is needed to establish when supplements should be ordered, how to ensure that they will be taken, and whether they are effective.

Factors contributing to the hospitalization of nursing home residents.

This anthropological study describes and analyzes the clinical and social-structural factors contributing to the hospitalization of nursing home residents. In 48.2% of the cases, hospitalization could have been avoided. Factors such as an insufficient number of adequately trained nursing staff, the inability of nursing staff to administer and monitor intravenous therapy, lack of diagnostic services, and pressure for transfer from the staff and family contributed to hospitalization. In the United States each year, an estimated 216,000 nursing home residents who are hospitalized might be treated in the nursing home, for a cost savings of $942,763,530.

Introducing quality assurance and medical audit into the UCSF medical center curriculum.

The experience gained by a medical school faculty in developing and piloting a course for undergraduate medical students in medical care evaluation led to a similar effort for house staff. It is recognized that if the profession is to fulfill the demand by society for social accountability in the use of resources for health care, medical care assessment and quality assurance mechanisms must become an intimate part of the clinical experience of medical students and house officers. Teaching these subjects requires a theoretical framework; introduction of content and skills appropriate to the level of the student and continuation of progressively more advanced training throughout medical education; use of assessment and quality assurance techniques by clinician-teachers themselves to provide models for the student; and continued evolution of pedagogic approach and course content based on developments in the area.

Acute hospital discharge of older patients and external control.

This article examines acute hospital discharge planning processes and the constraints imposed by external control, including third party payors and PSRO. Analysis suggests that availability of third party payment for services dominates the discharge plan. From the professional perspective, in-home services are often planned and provided only to the extent they meet the requirements of medical necessity; from the lay perspective, the services most required are those which preserve the social context. As a consequence, care providers, patients, and significant others become "caught" in regulations often unrelated to a reasonable plan of care designed to meet patient and family needs.
