Financial performance among adult day centers: results of a national demonstration program.

OBJECTIVES: This paper describes the financial performance (defined as percent of total expenses covered by net operating revenue) of 16 adult day centers participating in a national demonstration program on day services for people with dementia, including examination of possible predictors of financial performance. METHODS: Participating sites submitted quarterly financial and utilization reports to the National Program Office. Descriptive statistics summarize the factors believed to influence financial performance. RESULTS: Sites averaged meeting 35% of expenses from self-pay and 29% from government (mainly Medicaid) revenue, totaling 64% of all (cash plus in-kind) expenses met by operating revenue. Examination of center characteristics suggests that factors related to meeting consumer needs, such as being open a full day (i.e., 7:30 am to 6:00 pm) rather than shorter hours, and providing transportation, may be related to improved utilization and, thus, improved financial performance. Higher fees were not related to lower enrollment, census, or revenue. CONCLUSIONS: Adult day centers are able to achieve financial viability through a combination of operating (i.e., fee-for-service) and non-operating revenue. Operating revenue is enhanced by placing emphasis on consumer responsiveness, such as being open a full day. Because higher fees were not related to lower utilization, centers should set fees to reflect actual costs. The figure of 64% of expenses met by operating revenue is conservative inasmuch as sites included in-kind revenue as expenses in their budgeting calculations, and percent of cash expenses met by operating revenue would be higher (approximately 75% for this group of centers).

Selective monitoring in abdominal aortic surgery.

Monitoring via a pulmonary artery catheter has been advocated for all patients undergoing abdominal aortic surgery. This study was performed to identify a subgroup of patients who could be safely monitored with a central venous catheter. One hundred twenty-eight consecutive patients undergoing elective infrarenal abdominal aortic surgery were prospectively evaluated for risk of developing perioperative myocardial dysfunction based on criteria determined by the history and physical examination, chest radiography, and electrocardiography. Forty-five patients were identified as having no clinical evidence of coronary artery disease. These patients were then monitored perioperatively using a central venous catheter. All patients monitored via a central venous catheter underwent surgery for abdominal aortic aneurysmal disease (66.7%) or aortoiliac disease (33.3%) without intraoperative complications. There were 15 postoperative complications in 12 (26.7%) patients, comprised mainly of pulmonary (7) and gastrointestinal (3) complications. The cardiac-related morbidity was 4.4 per cent and consisted of congestive heart failure (1) and renal failure (1). No perioperative myocardial infarctions were detected. One (2.2%) postoperative death secondary to aspiration pneumonia occurred. The results of this data suggest that there exists a subgroup of patients undergoing elective infrarenal abdominal aortic surgery that can be monitored safely via a central venous catheter in the perioperative period.

Characteristics of dementia-specific day programs.

Adult day programs are a rapidly growing alternative for community-based care for the elderly, but there are few descriptions of dementia-specific programs in the gerontologic literature. We present the first overview of such efforts in the United States with a national scope, using information provided by a pool of 283 applicants to the Robert Wood Johnson Foundation Dementia Care and Respite Services Program. Results show program consistency in hours of operation and use of professional staff, and variability in sources of funding and size of the community served. On the average, participant fees accounted for less than 25 percent of total revenues.

The prognostic significance of preoperative carcinoembryonic antigen levels in colorectal cancer. Results from NSABP (National Surgical Adjuvant Breast and Bowel Project) clinical trials.

This analysis explores the prognostic significance of preoperative carcinoembryonic antigen (CEA) levels in patients with colorectal cancer. The data were derived from 945 patients entered into two randomized prospective clinical trials of the National Surgical Adjuvant Breast and Bowel Project. A strong correlation was evident between preoperative CEA level and Dukes class. The mean CEA progressively increased with each Dukes category and the mean value for each of the four classes was significantly different. This relationship was prevalent whether the data were analyzed for all colorectal lesions regardless of location or specifically for right-sided colon tumors. The prognostic function of preoperative CEA level was independent of the number of positive histologic nodes. Preoperative CEA level correlated with the degree of lumen encirclement by tumor. Tumors that did not encircle more than one half the lumen were associated with significantly lower preoperative CEA levels than those that did. The presence or absence of lumen obstruction was unrelated to the preoperative CEA level. The relative risk of developing a treatment failure was associated with preoperative CEA, in both Dukes B and C patients, demonstrating that the prognostic significance of preoperative CEA was independent of Dukes class.

Titratable acidities of crystalline amino acid admixtures.

Titration curves for total parenteral nutrient (TPN) products were developed and used to determine the amount of alkali needed to make various pH changes. Equations and graphs for determining the titratable acidities of TPN solutions are presented. Samples of five crystalline amino acid products and of 1:1 mixtures of the products with 50% dextrose solutions were titrated to pH 7.4 (with a standard sodium bicarbonate solution) or 8.0 (with a standard sodium hydroxide solution). The samples titrated with sodium hydroxide were first adjusted to pH 5.0 with hydrochloric acid. The pH of the sample was measured after each 0.1-ml addition of hydroxide or bicarbonate to develop a titration curve. Titratable acidities for the five crystalline amino acid products varied widely, ranging from 13.4--45.2 meq of hydroxide/liter and from 135--420 meq of bicarbonate/liter. The amino acid/dextrose mixtures had titratable acidities ranging from 7.8--24.8 meq of hydroxide/liter and from 87--226 meq of bicarbonate/liter. The pH titration data can be used as a guide for determining the amount of base to add to TPN solutions to obtain the desired pH.

Compatibility of calcium chloride and calcium gluconate with sodium phosphate in a mixed TPN solution.

The maximum concentrations of phosphate that will remain soluble in a parenteral nutrient solution containing various concentrations of calcium chloride or calcium gluconate were determined. Various concentrations of sodium phosphate were mixed with FreAmine II (McGaw Laboratories), and the resulting solutions were mixed with 50% dextrose solutions containing various concentrations of calcium chloride or calcium gluconate. The final solutions were sealed and stored at 30 degrees C for 24 hours and then were inspected visually for precipitate formation. It was found that higher equivalent concentrations of phosphate are attainable when calcium gluconate, instead of calcium chloride, is used as the calcium source. Factors found to influence the concentrations of calcium and phosphate that are compatible in amino acid solutions are the calcium salt used, temperature and duration of storage, dextrose concentration, amino acid composition, pH, and other additives.

Visual compatibility of 30 additives with a parenteral nutrient solution.

The visual compatibility of 30 drug additives with total parenteral nutrient (TPN) solutions (4.25% amino acids, 25% dextrose injection) was studied. For each drug additive, three TPN solutions were mixed; two were stored for 22 hours at 4 C then allowed to equilibrate to room temperature for two hours. Two 25-ml samples from each TPN solution were examined immediately or after 25 hours for visual appearance, particulate matter levels and pH. A microscope was used to count and measure particles filtered from samples on a 0.8-micrometer filter. Only the TPN solutions containing amphotericin B showed any visual discoloration or precipitation. All amphotericin B samples and the 25-hour ampicillin sodium samples exceeded USP particulate matter specifications. Individual particulate matter levels of the other TPN solutions varied but met USP specifications. With the exception of tetracycline hydrochloride, which dropped the TPN solution's pH 0.9 units, the additives had little effect on pH of the TPN solutions (pH 6.45). Amphotericin B and ampicillin sodium were considered visually incompatible with TPN solutions. All other drug additives tested were visually compatible with TPN solutions.
