What value for whom? - provider perspectives on health examinations for asylum seekers in Stockholm, Sweden.

BACKGROUND: In Sweden asylum seekers are offered a voluntary health examination, free-of-charge (HE). The HE coverage is low. The organization and implementation of the HE involves collaboration between different agencies with different roles within the provision of health information and service. This study aimed to assess their perspectives on the barriers and facilitators regarding implementation of the HE, as well as on the purpose, content and value of the HE. METHOD: Thematic analysis of focus groups, individual and group interviews conducted between 2016 and 17 with 41 participants from various authorities and healthcare professionals involved in the delivery of HE in Stockholm. RESULTS: Suggestions were taken from interviewees of how to facilitate the uptake and delivery of HE through improved outreach to the target group with better collaboration, coordination and continuity between authorities. Apart from control of specific communicable diseases, the perceived ultimate goal of HE varied and was often vaguely formulated. Respondents desired better monitoring to assess the effects of HE and predict needs among asylum seekers. This included standardized procedures to promote equitable health care access and more explicit inclusion of mental health and other health dimensions in the HE. CONCLUSION: There are several possible avenues for improving HE coverage and uptake. However, ambiguity exists concerning the benefits of such efforts given the uncertainty of the value of HE. Lack of available data on health status, determinants of health and impact of HE among asylum seekers emerged as barriers preventing optimal approaches for the assessment of health needs. Implementation of standardized guidelines, procedures and documentation would aid the understanding. A more holistic approach beyond infectious diseases is necessary. This would only be useful if there is value in screening for such conditions. More research is required to assess the effectiveness and cost-effectiveness of HE and related screening policies in Sweden.

Discriminant validity of the 12-item version of the general health questionnaire in a Swedish case-control study.

BACKGROUND: The 12-item version of the General Health Questionnaire (GHQ-12) is widely used as a proxy for Affective Disorders in public health surveys, although the cut-off points for distress vary considerably between studies. The agreement between the GHQ-12 score and having a clinical disorder in the study population is usually unknown. AIMS: This study aimed to assess the criterion validity and to determine the sensitivity and specificity of the GHQ-12 in the Swedish population. METHODS: This study used 556 patient cases surveyed in specialized psychiatric care outpatient age- and sex-matched with 556 controls from the Stockholm Health Survey. Criterion validity for two scoring methods of GHQ-12 was tested using Receiver Operating Characteristics (ROC) analyses with Area Under the Curve (AUC) as a measure of agreement. Reference standard was (1) specialized psychiatric care and (2) current depression, anxiety or adjustment disorder. RESULTS: Both the Likert and Standard GHQ-12 scoring method discriminated excellently between individuals using specialized psychiatric services and healthy controls (Likert index AUC = 0.86, GHQ index AUC = 0.83), and between individuals with current disorder from healthy controls (Likert index AUC = 0.90, GHQ index AUC = 0.88). The best cut-off point for the GHQ index was ≥4 (sensitivity = 81.7 and specificity = 85.4), and for the Likert index ≥14 (sensitivity = 85.5 and specificity = 83.2). CONCLUSIONS: The GHQ-12 has excellent discriminant validity and is well suited as a non-specific measure of affective disorders in public mental health surveys.
