Continuity of care and health outcomes among persons with severe mental illness.

OBJECTIVES: Continuity of care is considered to be essential to the effective treatment of persons with severe mental illness, yet evidence to support the association between continuity and outcomes is sparse because of a lack of longitudinal studies and of comprehensive continuity measures. The purpose of this study was to examine the relationship between continuity of care and outcomes. METHODS: A new multilevel measure of service continuity, the Alberta Continuity of Services Scale for Mental Health (ACSS-MH), was used in a 17-month follow-up study of 486 adults with severe mental illness in three health regions of Alberta, Canada. RESULTS: Endpoint information was obtained for 411 participants (85 percent). The mean continuity score reported by patients was 131+/-20 out of a possible 185. The mean continuity score as rated by observers was 39+/-10 out of a possible 59. Higher levels of observer-rated continuity were associated with older age, lower annual household income, a diagnosis of psychotic disorder, and no suicidality or alcohol use. Continuity was also significantly associated with a better quality of life at endpoint (generic and disease specific), better community functioning, lower severity of symptoms, and greater service satisfaction. The associations between continuity and quality of life held after adjustment for empirically identified confounders. CONCLUSIONS: Positive relationships between continuity of care and health outcomes among persons with severe mental illness suggest that efforts at improving continuity in and among mental health services are worthwhile.

Continuity of care in mental health services: toward clarifying the construct.

OBJECTIVE: To clarify "continuity of care" (COC), a construct associated with the delivery of services for persons suffering from severe and persistent mental illness (SPMI), with attention to the service recipient's perception of COC. METHOD: The study involved a systematic appraisal of the literature on COC, supplemented by interviews with 36 SPMI patients and their families. Statements highlighting attributes of COC were extracted from both sources. RESULTS: Comments by patients and families corresponded to descriptions of COC in the mental health literature. Attribute classifications by independent teams of judges showed good consistency. The following 4 attribute domains of the COC construct were identified: service delivery, accessibility, relationship base, and individualized care. CONCLUSIONS: Service recipients' perceptions of COC overlapped with representations of the construct in the mental health literature. The qualitative inquiry resulted in a draft, 47-item, self-report questionnaire for use in studies of interventions designed to facilitate COC.

Risk factors for early-onset group B streptococcal disease in neonates: a population-based case-control study.

BACKGROUND: Infection with group B streptococcus (GBS) is a major cause of neonatal illness and death. We examined the antenatal and perinatal risk factors for early-onset GBS disease among neonates. METHODS: We identified cases by population-based surveillance in all microbiology laboratories serving Alberta. A case was defined as any instance of a positive sterile-site GBS culture in an infant born between 1993 and 1997 who was either less than 7 days old or stillborn after 20 weeks' gestation. We randomly selected controls from a computer-compiled list of all hospital births, including stillbirths after 20 weeks' gestation, in Alberta during the study period. To increase power, we chose 5 or 6 control infants born in the same year as each case infant. We reviewed hospital, prenatal clinic and physician health records and, between 1997 and 1999, conducted maternal interviews by telephone. RESULTS: There were no differences between the 90 cases and 489 controls in sociodemographic variables or in many reproductive and behavioural variables. Case infants were more likely than control infants to be of low birth weight (odds ratio [OR] 3.60, 95% confidence interval [CI] 1.68-7.65), to have been delivered preterm (OR 3.89, 95% CI 2.08-7.27), or to have a mother with amnionitis (OR 15.03, 95% CI 5.58-41.89), intrapartum fever (OR 4.65, 95% CI 2.48-8.69) or premature rupture of the membranes (OR 2.39, 95% CI 1.38-4.14). After adjustment for potential confounders, intrauterine fetal monitoring was associated with a more than 2-fold increase in the risk of neonatal GBS disease (OR 2.24, 95% CI 1.22-4.13). INTERPRETATION: Intrauterine fetal monitoring should be added to the list of risk factors in risk-based screening. Since many of the cases had no identifiable maternal risk factors, universal screening for GBS may be appropriate.
