Variations in older people's use of general practitioner consultations and the relationship with mortality rate in Vantaa, Finland in 2003-2014

Objective: It is generally expected that the growth of the older population will lead to an increase in the use of health care services. The aim was to examine the changes in the number of visits made to general practitioners (GP) by the older age groups, and whether such changes were associated with changes in mortality rates. Design and setting: A register-based observational study in a Finnish city where a significant increase in the older population took place from 2003 to 2014. The number of GP visits made by the older population was calculated, the visits per person per year in two-year series, together with respective mortality rates. Subjects: The study population consisted of inhabitants aged 65 years and older (65+) in Vantaa that visited a GP in primary health care. Main outcome measures: The number of GP visits per person per year in the whole older population during the study years. Results: In 2009-2010, there was a sudden drop in GP visits per person in the younger (65-74 years) age groups examined. In the population aged 85+, use of GP visits remained at a fairly constant level. The mortality rate decreased until the year 2008. After that, the positive trend ended and the mortality rate plateaued. Conclusions: Simultaneously with the decline in GP visits per person in the older population, the mortality rate leveled off from its positive trend in 2009-2010. Factors identified being associated with the number of GP consultations were organizational changes in primary health care, economic recession causing retrenchment, and even vaccinations during the swine flu epidemic.Peer reviewe

A Primary Care Emergency Service Reduction Did Not Increase Office-Hour Service Use : A Longitudinal Follow-up Study

This study, conducted in a Finnish city, examined whether decreasing emergency department (ED) services in an overcrowded primary care ED and corresponding direction to office-hour primary care would guide patients to office-hour visits to general practitioners (GP). This was an observational retrospective study based on a before-and-after design carried out by gradually decreasing ED services in primary care. The interventions were (a) application of ABCDE-triage combined with public guidance on the proper use of EDs, (b) cessation of a minor supplementary ED, and finally (c) application of "reverse triage" with enhanced direction of the public to office-hour services from the remaining ED. The numbers of visits to office-hour primary care GPs in a month were recorded before applying the interventions fully (preintervention period) and in the postintervention period. The putative effect of the interventions on the development rate of mortality in different age groups was also studied as a measure of safety. The total number of monthly visits to office-hour GPs decreased slowly over the whole study period without difference in this rate between pre- and postintervention periods. The numbers of office-hour GP visits per 1000 inhabitants decreased similarly. The rate of monthly visits to office-hour GP/per GP did not change in the preintervention period but decreased in the postintervention period. There was no increase in the mortality in any of the studied age groups (0-19, 20-64, 65+ years) after application of the ED interventions. There is no guarantee that decreasing activity in a primary care ED and consecutive enhanced redirecting of patients to the office-hour primary care systems would shift patients to office-hour GPs. On the other hand, this decrease in the ED activity does not seem to increase mortality either.Peer reviewe

Magia: Robust Automated Image Processing and Kinetic Modeling Toolbox for PET Neuroinformatics

Processing of positron emission tomography (PET) data typically involves manual work, causing inter-operator variance. Here we introduce the Magia toolbox that enables processing of brain PET data with minimal user intervention. We investigated the accuracy of Magia with four tracers: [C-11]carfentanil, [C-11]raclopride, [C-11]MADAM, and [C-11]PiB. We used data from 30 control subjects for each tracer. Five operators manually delineated reference regions for each subject. The data were processed using Magia using the manually and automatically generated reference regions. We first assessed inter-operator variance resulting from the manual delineation of reference regions. We then compared the differences between the manually and automatically produced reference regions and the subsequently obtained binding potentials and standardized-uptake-value-ratios. The results show that manually produced reference regions can be remarkably different from each other, leading to substantial differences also in outcome measures. While the Magia-derived reference regions were anatomically different from the manual ones, Magia produced outcome measures highly consistent with the average of the manually obtained estimates. For [C-11]carfentanil and [C-11]PiB there was no bias, while for [C-11]raclopride and [C-11]MADAM Magia produced 3-5% higher binding potentials. Based on these results and considering the high inter-operator variance of the manual method, we conclude that Magia can be reliably used to process brain PET data

Interindividual variability and lateralization of mu-opioid receptors in the human brain

Alterations in the brain's mu-opioid receptor (MOR) system have been associated with several neuropsychiatric disorders. Central MOR availability also varies considerably in healthy individuals. Multiple epidemiological factors have been proposed to influence the MOR system, but due to small sample sizes the magnitude of their influence remains inconclusive. We compiled [C-11] carfentanil positron emission tomography scans from 204 individuals with no neurologic or psychiatric disorders, and estimated the effects of sex, age, body mass index (BMI) and smoking on [C-11]carfentanil binding potential using between-subject regression analysis. We also examined hemispheric differences in MOR availability. Older age was associated with increase in MOR availability in frontotemporal areas but decrease in amygdala, thalamus, and nucleus accumbens. The age-dependent increase was stronger in males. MOR availability was globally lowered in smokers but independent of BMI. Finally, MOR availability was higher in the right versus the left hemisphere. The presently observed variation in MOR availability may explain why some individuals are prone to develop MOR-linked pathological states, such as chronic pain or psychiatric disorders. Lateralized MOR system may reflect hemispheric work specialization in central emotion and pain processes

Impact of the ABCDE triage in primary care emergency department on the number of patient visits to different parts of the health care system in Espoo City

<p>Abstract</p> <p>Background</p> <p>Many Finnish emergency departments (ED) serve both primary and secondary health care patients and are therefore referred to as combined emergency departments. Primary care doctors are responsible for the initial assessment and treatment. They, thereby, also regulate referral and access to secondary care. Primary health care EDs are easy for the public to access, leading to non-acute patient visits to the emergency department. This has caused increased queues and unnecessary difficulties in providing immediate treatment for urgent patients. The primary aim of this study was to assess whether the flow of patients was changed by implementing the ABCDE-triage system in the EDs of Espoo City, Finland.</p> <p>Methods</p> <p>The numbers of monthly visits to doctors were recorded before and after intervention in Espoo primary care EDs. To study if the implementation of the triage system redirects patients to other health services, the numbers of monthly visits to doctors were also scored in the private health care, the public sector health services of Espoo primary care during office hours and local secondary health care ED (Jorvi hospital). A face-to-face triage system was applied in the primary care EDs as an attempt to provide immediate treatment for the most acute patients. It is based on the letters A (patient sent directly to secondary care), B (to be examined within 10 min), C (to be examined within 1 h), D (to be examined within 2 h) and E (no need for immediate treatment) for assessing the urgency of patients' treatment needs. The first step was an initial patient assessment by a health care professional (triage nurse). The introduction of this triage system was combined with information to the public on the "correct" use of emergency services.</p> <p>Results</p> <p>After implementation of the ABCDE-triage system the number of patient visits to a primary care doctor decreased by up to 24% (962 visits/month) as compared to the three previous years in the EDs. The Number of visits to public sector GPs during office hours did not alter. Implementation of ABCDE-triage combined with public guidance was associated with decreased total number of doctor visits in public health care. During same period, the number of patient visits in the private health care increased. Simultaneously, the number of doctor visits in secondary health care ED did not alter.</p> <p>Conclusions</p> <p>The present ABCDE-triage system combined with public guidance may reduce patient visits to primary health care EDs but not to the secondary health care EDs. Limiting the access of less urgent patients to ED may redirect the demands of patients to private sector rather than office hours GP services.</p
