  Background Depression is common in old age and is associated with both disability, increased mortality and increased impairment from physical diseases. Aim To estimate the prevalence of depression among old patients in Norwegian general practice, to evaluate the extent they talk about it during their consultation, if it was previously known or suspected by their general practitioner (GP), and how frequent the depressed patients visit their GP. Design and setting Cross-sectional study among patients and GPs at 18 primary care clinics in the south of Norway. Method Patients ≥65 years who visited their GP were asked to complete the Patient Health Questionaire-9 (PHQ9). The GPs reported what kind of issues the patient presented at the consultation, if a current depression were known, and the consultation frequency. Results 44 (11%) of 383 patients reported moderate or severe depressive symptoms (PHQ9≥10). Among the cases with data from both patient and GP (369), 38 patients (10%) reported moderately depressive symptoms. Of these only 12 (32%) mentioned psychological problems to their GP during their consultation, 12 (32%) were neither known to the GP with previous depression nor suspected by the GP of having a current one, and 68% of them visit their GP ≥ 5 times a year. Conclusion Elderly patients tend to speak little of their depression to the GP. Almost 1 of 3 elderly patients with moderate depressive symptoms were unrecognized by their GP. GPs should more often suspect potential mental health problems in old patients who come frequently to visits. Copyright © 2022, The Authors.

  Objective A prospective cohort study on changes of health complaints after removal of amalgam restorations was carried out at the request of the Norwegian Directorate of Health. The aim was to provide and evaluate experimental treatment to patients with health complaints attributed to dental amalgam fillings. Methods Patients (n = 32) with medically unexplained physical symptoms (MUPS), which were attributed to dental amalgam restorations had all their amalgam restorations removed and replaced with other dental restorative materials. Samples of blood were collected before and 1 year after removal of the fillings, and concentration of inorganic mercury (I-Hg), methylmercury (MeHg), silver (Ag) and selenium (Se) in serum was determined by inductively coupled plasma–sector field mass spectrometry. The comparison groups (one with MUPS but without attribution to amalgam [n = 28] and one group of healthy individuals [n = 19]) received no treatment. The participants responded to questionnaires at baseline and at follow-up after 1 and 5 years. Results Concentration of I-Hg and Ag in serum decreased significantly after removal of all amalgam restorations. Concentration of MeHg and Se in serum were not changed. Intensity of health complaints was significantly reduced after amalgam removal, but there were no statistically significant correlations between exposure indicators and health complaints. Conclusions Removal of all amalgam restorations is followed by a decrease of concentration of I-Hg and Ag in serum. The results support the hypothesis that exposure to amalgam fillings causes an increase of the daily dose of both I-Hg and Ag. Even though intensity of health complaints decreased after removal of all amalgam restorations there was no clear evidence of a direct relationship between exposure and health complaints.

  Background Independent medical evaluations are used to evaluate degree and reason for work disability, uncertainty around the functional status, and/or the employee’s rehabilitation potential in several jurisdictions, but not in Norway. The main aim of this trial was to test the return to work effect of independent medical evaluation (IME) (summoning and consultation) compared to treatment as usual (TAU) in Norway, for workers who have been on continuous sick leave for 6 months. Methods This was a pragmatic randomised controlled trial including all employees aged 18–65 years, sick-listed by their general practitioner and on full or partial sick leave for the past 26 weeks in Hordaland County, Norway in 2015/16. Trial candidates were drawn from a central register at the Norwegian Labour and Welfare Administration at 22 weeks of sick leave. Pregnant women, individuals with cancer or dementia diagnoses, those with secret address, employed by NAV or sick listed by the specialist health services were excluded. Separate regression analyses were conducted to investigate the “intention-to-treat” and “treatment on the treated” effects, using the ordinary least squares and instrumental variable methods, respectively. Results After exemption based on predefined exclusion criteria, 5888 individuals were randomised to either IME (n = 2616) or TAU (n = 2599). The final intervention group constitutes 1698 individuals, of which 937 attended the IME consultation. No baseline differences were found between the IME and TAU group regarding gender, age, and previous sick leave. Individuals attending the IME were older than those who cancelled the appointment ((47/45), p = 0.006) and those who did not show up without cancelling ((47/42), p < 0.001). Mainly the IME physician agreed with the regular GP upon level of sick leave. In cases with different assessments, the difference tended to be towards a lower sick leave level. There were no intention to treat or treatment on the treated effect on days of sick leave after randomisation during follow up. Conclusions Overall, the analyses showed no effect of IME on changes in sick leave for sick listed employees. This result was consistent for those who were offered an IME consultation (intention to treat) and those who undertook an IME consultation (treatment on the treated).

  Background: An individualized patient reported outcome (PRO) has recently been recommended within LBP research, but no study has evaluated this instrument with commonly applied PROs. Moreover, the impact of psychological factors has mostly been assessed for disease-specific instruments. The objective of this study was to assess the predictive value of illness perceptions, pain catastrophizing and psychological distress on 12 month outcomes assessed by specific, generic and individualized PROs recommended in low back pain (LBP). Methods: Secondary analysis of patients with sub-acute or chronic LBP recruited for a cluster randomized controlled trial in primary care who completed a self-administered questionnaire at baseline and 12 months. 12 month scores for the Roland Morris Disability Questionnaire (RMDQ), the EuroQol (EQ-5D), and the Patient Generated Index (PGI) were dependent variables in hierarchical regression analysis. Independent variables included baseline scores for the Brief Illness Perceptions Questionnaire (Brief IPQ), Hopkins Symptom Check List (HSCL-25), Pain Catastrophizing Scale (PCS), health/ clinical and sociodemographic variables. Results: Of the 216 eligible patients included, 203 patients responded to the baseline questionnaire and 150 (74%) responded at 12 months. The mean age was 38.3 (SD 10.2) years and 57.6% were female. The Brief IPQ showed a statistically significant variation in the 12-months score of all the PROs, explaining 2.5% in RMDQ, 7.9% in EQ-5D, and 3.6% in PGI. Most of the explained variation for EQ-5D scores related to illness perceptions. The PCS explained 3.7% of the RMDQ and 2.5% in the EQ-5D scores. The HSCL-25 did not make a significant contribution. Conclusion: Illness perceptions and pain catastrophizing were associated with 12-month outcomes as assessed by condition-specific, generic and individualized PROs. The Brief IPQ and PCS have relevance to applications in primary care that include interventions designed to enhance psychological aspects of health and where the contribution of such variables to outcomes is of interest. Further studies should assess whether the Brief IPQ perform similarly in LBP populations in other health care settings.
