Predictors for readmission risk of new patients: the Nordic Comparative Study on Sectorized Psychiatry.

OBJECTIVE: Predictors for readmission risk were investigated in this study, which forms part of the Nordic Comparative Study on Sectorized Psychiatry. METHOD: Included were a total of 837 consecutive 'new' patients (not in contact with the psychiatric services for at least 18 months) admitted to in-patient stay during a period of 1 year to seven psychiatric hospitals in four Nordic countries. RESULTS: Multivariate survival analyses showed that younger age predicted increased readmission risk. Stratifying on gender, diagnostic group and sector revealed a general pattern concerning age which was the only consistent main effect. Living alone and unemployed increased readmission risk in the non-psychosis group, while receipt of aftercare decreased readmission risk in the psychosis group. A curvilinear relationship was found between availability of psychiatric resources and readmission risk: an intermediate amount of resources was associated with increased risk. CONCLUSION: Our findings support a hypothesis that readmission risk is multifactorially determined and that interactions have to be considered.

The Nordic Comparative Study on Sectorized Psychiatry--length of in-patient stay.

OBJECTIVE: Length of stay (LOS) of 'first' in-patient episodes was investigated in this study, which is part of the Nordic Comparative Study on Sectorized Psychiatry. METHOD: A total of 837 consecutive 'new' patients (not in contact with the psychiatric services for at least 18 months) admitted as in-patients during a period of 1 year to seven psychiatric hospitals in four Nordic countries were included. RESULTS: Survival analyses showed considerable differences in LOS between the hospitals, and the factors analysed in this study could not explain this variance. Older age, being female, having no children at home, psychosis, planned admission and out-patient contacts were all associated with increased LOS. CONCLUSION: Stratifying on gender, diagnostic group and hospital revealed a general pattern of associations except for age.

The Nordic Comparative Study on Sectorized Psychiatry: continuity of care related to characteristics of the psychiatric services and the patients.

The problem addressed in this paper is how continuity of care is related to characteristics of psychiatric services, previous events in a patient's pattern of care and patient characteristics. The present paper is a part of a Nordic Comparative Study on Sectorized Psychiatry in seven catchment areas in four Nordic countries. One-year-treated-incidence cohorts were used. Each patient was followed for 1 year after the first contact with the psychiatric service. Continuity of care was measured by the time from discharge from hospital to the first subsequent day-patient or outpatient contact. Notable findings were large differences in the continuity of care in the seven services, high proportions of discharges without any aftercare contacts and long time lags between discharges and aftercare contacts in most of the catchment areas. A Cox regression analysis revealed that aftercare following hospitalisation seems to be more probable if the outpatient services are located geographically close to the patients, if the hospitalisation lasted between 2 and 4 weeks, if there was a community care contact shortly before the hospital admission and if the patient is not retired and not divorced. Staff resources were not related to continuity of care.

The Nordic Comparative Study on Sectorized Psychiatry: patients who use only psychiatric in-patient care in comprehensive community-based services--a 1-year follow-up study.

In the present paper a sample of patients using psychiatric in-patient care only is characterized and analysed with regard to characteristics of the psychiatric services. This paper forms part of the Nordic Comparative Study on Sectorized Psychiatry, designed to investigate contact rates and use of psychiatric care by new patients in 7 catchment areas in 4 Nordic countries during a 1-year follow-up. One-year treated incidence cohorts were used. The logistic regression analysis revealed that the variable 'psychiatric service' was one of the statistically significant determinants of using only in-patient care during the follow-up. The diagnostic groups with the highest probability of using only in-patient care were dependencies and functional psychoses. The following factors were associated with a high risk of using only in-patient care: older age, being referred by another psychiatrist, having received previous psychiatric in-patient care, male sex, being retired, and not living with one's parents or a partner. Patients who used only in-patient care had fewer admissions and days in in-patient care than others during the 1-year follow-up period. Lack of 24-hour emergency services in out-patient care correlated positively with the use of only in-patient care.

The Nordic Comparative Study on Sectorized Psychiatry: contact rates and use of services for patients with a functional psychosis.

As part of a Nordic comparative study on contact rates of new patients and use of services in seven catchment areas, contact rates and use of services for patients with a functional psychosis during a 1-year follow-up period were investigated. The highest contact rates were found in two large city catchment areas in Stockholm and Copenhagen. Compared to other patients in the cohorts, patients with a functional psychosis were more often found to be unemployed and living alone. They also showed more extensive service use in terms of both voluntary and compulsory admissions, and in the use of day-care facilities. In addition, they were more often multiple users of in-patient care (> or =3 admissions during the follow-up period). Large differences in service use among patients with a functional psychosis were discovered between the catchment areas, with the most extensive use of voluntary in-patient care and day-care facilities in Frederiksberg. Patients most frequently had compulsory admissions in Bodö and least frequently had them in Frederiksberg. Out-patient services were most frequently used in Stockholm. Correlations between levels of resources and use of services for patients with a functional psychosis were in general low, except for the rates of short-term beds, which showed a strong and significant correlation with the number of days in voluntary in-patient care (r=0.89).

The Nordic comparative study on sectorised psychiatry: repeated emergency admissions to inpatient care during a 1-year follow-up.

The emergency admissions to hospital care in six psychiatric services in four Nordic countries were explored as a part of a Nordic comparative study on sectorised psychiatry. One year treated incidence cohorts were used, with the total cohort comprising 2,454 patients. Of the 803 patients who were admitted to inpatient care during a 1-year follow-up, 82% had at least one emergency admission and 23% repeated emergency admissions. The definition for the repeated emergency admissions was at least two admissions during the follow-up. The mean length of stay in emergency inpatient care per treatment episode for this patient subgroup was 28 days. Their emergency inpatient episodes constituted 30% of all inpatient days during the follow-up. However, the variations between the services and diagnostic subgroups were large. The results of a logistic regression analysis indicated that the following variables predicted repeated emergency admissions: inpatient care at index contact, emergency outpatient contacts or no planned hospital admissions during the follow-up, psychiatric service, age under 45 years, and a diagnosis of psychosis, personality disorder or dependency. The repeated emergency admissions were related to the existence of a special service unit for abusers but not to the rates of outpatient staff or acute beds in the services, to geographical distances, referral practice or existence of emergency services.

The Nordic Comparative Study on Sectorized Psychiatry. III. Accessibility of psychiatric services, degree of urbanization and treated incidence.

As part of a Nordic Comparative Study on Sectorized Psychiatry, accessibility of psychiatric services and degree of urbanization in seven catchment areas were related to treated incidence. One-year treated incidence cohorts were used. Accessibility was assessed according to referral practice, existence of a round the clock emergency service and geographical location of the services. Accessibility was surprisingly weakly associated with treated incidence. Easy access to the psychiatric services was not related to a high treated incidence of less severe psychiatric problems at the expense of patients suffering from severe illness. Geographical distance to the services did not predict the demand for services. A positive correlation was found between the degree of urbanization and treated incidence of psychoses but not of other diagnostic groups.

The Nordic comparative study on sectorized psychiatry. I. Treated point prevalence and characteristics of the psychiatric services.

Comparative studies relating characteristics of psychiatric services to rates of treated prevalence are scarce. As part of a Nordic comparative study on sectorized psychiatry, a point-prevalence study was performed in 5 sectorized psychiatric services with comprehensive service facilities for a defined population under responsibility. The rates of treated prevalence on a census day were related to a number of characteristics of the respective services and to accessibility of care. The results showed a great variation in one-day point prevalence in the 5 services, with almost fourfold differences. There were also marked differences in the diagnostic distribution of the cohorts. A positive correlation was found between number of beds and point prevalence, measured both as total point prevalence and impatient prevalence. The rates of beds and psychiatrists were most strongly related to the prevalence of patients with organic disorders and functional psychoses. A closed referral system was associated with a lower level of treated prevalence.
