Medical patients' assessments of their care during hospitalization: insights for internists.

OBJECTIVE: To assess, from the patient's perspective, selected aspects of the quality of inpatient hospital care in the United States. DESIGN: A cross-sectional survey, using telephone interviews of patients discharged from the medical services of a probability sample of 62 public and private, nonprofit, nonfederal acute care hospitals in the United States. The participating patients reported; discrete, clinically important elements of hospital care; preferences for involvement in care; health status; sociodemographic characteristics; and overall satisfaction with their hospitalization. PATIENTS/PARTICIPANTS: 2,839 patients drawn as a probability sample. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: For 32 of the 50 questions about potential problems encountered during hospitalization, at least 10% of the patients gave a response indicating a problem. One-third of the patients having a physician (31.8%) reported that that physician did not care for them during hospitalization. Other frequently reported problems included not receiving information about the hospital routine (45.1%), not being told whom to ask for help (33.9%), having pain that could have been relieved by more prompt attention (19.9%), and not being given adequate information and guidance about activities and care after discharge from the hospital (21.4-36.1%). Most patients preferred to be informed about important aspects of their care (94.7%), but their preferences for involvement in care varied widely. CONCLUSIONS: Information from hospitalized medical patients identified several areas of concern that should be the focus of attention and could lead to systematic restructuring of hospital-based care.

Photosynthesis by isolated chloroplasts. Inhibition by DL-glyceraldehyde of carbon dioxide assimilation.

Photosynthetic carbon assimilation and associated CO(2)-dependent O(2) evolution by chloroplasts isolated from pea shoots and spinach leaves is almost completely inhibited by 10mm-dl-glyceraldehyde. The inhibitor is without appreciable effect on photosynthetic electron transport, photophosphorylation, the carboxylation of ribulose 1,5-diphosphate or the reduction of 3-phosphoglycerate, but apparently blocks the conversion of triose phosphate into ribulose 1,5-diphosphate.

Phosphoglycerate as a hill oxidant in a reconstituted chloroplast system.

The ability of intact chloroplasts to evolve oxygen when illuminated in the presence of 3-phosphoglycerate is lost following osmotic shock but may be largely restored by the addition of ATP, catalytic amount of nicotinamide adenine dinucleotide phosphate, ferredoxin, and a soluble fraction derived from chloroplasts. In the presence of uncoupling agents and ATP, the rate is faster than that supported by intact chloroplasts. In the absence of uncoupling agents, the ATP requirement may be partially met by photophosphorylation.
