The effects of long-term fasting on the prognosis and hospital economy of hospitalised patient have not been established. To clarify the effects of long-term fasting on the prognosis and hospital economy of hospitalised patients, we conducted a prospective observational study on the length of hospital stay of patients hospitalised at thrity-one private university hospitals in Japan. We conducted a prospective observational study on the effects of fasting period length on the length of hospital stay and outcome of patients hospitalised for 3 months in those hospitals. Of the 14 172 cases of hospitalised patients during the target period on the reference day, 770 cases (median 71 years old) were eligible to fast for the study. The length of hospital stay for fasting patients was 33 (4–387) days, which was about 2·4 times longer than the average length of hospital stay for all patients. A comparative study showed the length of hospital stay was significantly longer in the long-term-fasting (fasting period > 10 d; n 386) group than in the medium-term-fasting (< 10 d; n 384) group (median 21 v. 50; P < 0·0001). Although the discharge to home rate was significantly higher in the medium-term-fasting group (71·4 % v. 36·5 %; P < 0·0001), the mortality rate was significantly higher in the long-term fasting group (10·8 % v. 25·8 %; P < 0·0001). It was verified that the longer the fasting period during hospitalisation, the longer the length of hospital stay and lower home discharge rate, thus indicating that patient quality of life and hospital economy may be seriously dameged.

Nutritional status (NS) monitoring is an essential step of the nutrition care process. To assess changes in NS throughout hospitalisation and its ability to predict clinical outcomes, a prospective cohort study with patients over 18 years of age was conducted. The Subjective Global Assessment (SGA) was performed within 48 h of admission and 7 d later. For each patient, decline in NS was assessed by two different methods: changes in SGA category and severe weight loss alone (≥2 % during the first week of hospitalisation). Patients were followed up until discharge to assess length of hospital stay (LOS) and in-hospital mortality and contacted 6 months post-discharge to assess hospital readmission and death. Out of the 601 patients assessed at admission, 299 remained hospitalised for at least 7 d; of those, 16·1 % had a decline in SGA category and 22·8 % had severe weight loss alone. In multivariable analysis, decline in SGA category was associated with 2-fold (95 % CI 1·06, 4·21) increased odds of prolonged LOS and 3·6 (95 % CI 1·05, 12·26) increased odds of hospital readmission at 6 months. Severe weight loss alone was associated with 2·5-increased odds (95 % CI 1·40, 4·64) of prolonged LOS. In conclusion, deterioration of NS was more often identified by severe weight loss than by decline in SGA category. While both methods were associated with prolonged LOS, only changes in the SGA predicted hospital readmission. These findings reinforce the importance of nutritional monitoring and provide guidance for further research to prevent short-term NS deterioration from being left undetected.

This paper describes the development and testing of a European version of the Appropriateness Evaulation Protocol (AEP). It stemmed from the original U.S. version and the multiple adaptations and modifications made previously and separately by researchers in European countries. The group was particularly concerned with developing a common list of reasons for inappropriate admissions and days of stay, since the principal goal was to enable an understanding of inappropriate hospital use and potential solutions within local health and social care systems. Developing a common EU-AEP included several steps. First, each national instrument was translated from the national language to English. These back translations were compared with each other and with the US-AEP. A working group analyzed the content of the lists of reasons published in the literature and proposed a novel conceptual approach. On the basis of workshop discussions, a draft of a common European version was circulated to each participant for agreement. In the EU-AEP, the clinical criteria for the appropriateness of admission include 10 related to patient condition and five to clinical services. The criteria for the appropriateness of days of care include 10 covering medical services, six for life support/nursing services, and eight related to patient condition. The proposed core list of reasons of inappropriateness distinguish clearly between two concepts: a) the level of care required by the patient; and b) the reason why this level of care was not used. The first list would thus refer to the nature of resources and facilities required, while the second would focus more on the efficient organization of those resources. A validated European tool to assess inappropriate hospital admissions and hospital days of stay and their causes might be used to assess the need for resources for inpatient care as well as for outpatient care. Assessing the reasons for inadequacies might lead also to the examination of organizational questions. Finally, a common tool allows comparisons between countries concerning the frequency of inappropriate admissions and days of stay and their reasons in relation to the different organizations of health care across Europe.
