Relational continuity may give better clinical outcomes in patients with serious mental illness - a systematic review.

BACKGROUND: Continuity of care is considered important for results of treatment of serious mental illness (SMI). Yet, evidence of associations between relational continuity and different medical and social outcomes is sparse. Research approaches differ considerably regarding how to best assess continuity as well as which outcome to study. It has hitherto been difficult to evaluate the importance of relational continuity of care. The aim of this systematic review was to investigate treatment outcomes, including effects on resource use and costs associated with receiving higher relational continuity of care for patients with SMI. METHODS: Eleven databases were searched between January 2000 and February 2021 for studies investigating associations between some measure of relational continuity and health outcomes and costs. All eligible studies were assessed for study relevance and risk of bias by at least two independent reviewers. Only studies with acceptable risk of bias were included. Due to study heterogeneity the synthesis was made narratively, without meta-analysis. The certainty of the summarized result was assessed using GRADE. Study registration number in PROSPERO: CRD42020196518. RESULTS: We identified 8 916 unique references and included 17 studies comprising around 300 000 patients in the review. The results were described with regard to seven outcomes. The results indicated that higher relational continuity of care for patients with serious mental illness may prevent premature deaths and suicide, may lower the number of emergency department (ED) visits and may contribute to a better quality of life compared to patients receiving lower levels of relational continuity of care. The certainty of the evidence was assessed as low or very low for all outcomes. The certainty of results for the outcomes hospitalization, costs, symptoms and functioning, and adherence to drug treatment was very low with the result that no reliable conclusions could be drawn in these areas. CONCLUSIONS: The results of this systematic review indicate that having higher relational continuity of care may have beneficial effects for patients with severe mental illness, and no results have indicated the opposite relationship. There is a need for better studies using clear and distinctive measures of exposure for relational continuity of care.

Outcomes associated with higher relational continuity in the treatment of persons with asthma or chronic obstructive pulmonary disease: A systematic review.

Background: Asthma and chronic obstructive pulmonary disease (COPD) are chronic conditions where relational continuity of care, as in regularly meeting the same health care provider, creates opportunities for monitoring and adjustment of treatment based on an individual's changing needs, potentially affecting quality of delivered care. The aim of this systematic review was to investigate the effects of relational continuity in the treatment of persons with asthma or COPD. Methods: Eleven databases (CINAHL, Medline, PsycINFO, Scopus, Embase, Cochrane Library, Database of Systematic Review of Effects, DARE, Epistemonikos, NICE Evidence Search, KSR Evidence and AHRQ) were searched between January 1, 2000, and February 1 - 4, 2021, for controlled and observational studies about relational continuity and health outcomes for persons with asthma and/or COPD. Inclusion criteria were studies investigating an index or aspect relevant to relational continuity between a health professional/team of health professionals and patients. After screening, and assessment of study relevance and quality by at least two independent reviewers, studies with acceptable risk of bias were included and summary data was extracted from the publications. Main outcomes were mortality, morbidity (including health care utilization) and cost measures. Syntheses without metanalyses were performed due to considerable study heterogeneity. The certainty of the summarized result was assessed using GRADE (the Grading of Recommendations Assessment, Development and Evaluation). PROSPERO study registration number: CRD42020196518. Findings: We identified 2824 unique references and included 15 studies (14 observational and 1 randomized controlled trial) in the review, from which results were derived for six outcomes. For persons with asthma or COPD we found that higher compared to lower relational continuity of care prevents premature mortality (low certainty; 2 studies, 111 545 participants), lowers risk of emergency department visits (low certainty, 5 studies, 362 305 participates) and risk of hospitalization (moderate certainty, 9 studies, 525 716 participants), and lowers health care costs (low certainty; 4 studies, 390 682 participants). Results regarding treatment adherence (1 study, 971 participants) and patient perceptions (3 studies, 2026 participants) were assessed as having very low certainty. Interpretation: Low to moderate certainty evidence suggests that higher versus lower relational continuity of care for persons with asthma or COPD prevents premature mortality, lowers risks of unplanned health care utilization and reduces health care costs. The results may be of value when planning care for individuals and for policymakers in organizing health care and developing guidelines for treatment and follow-up routines. Funding: None.

[How do we want to organize health centres? 838 Swedish general practitioners' attitudes to a personal patient list]. / Så vill vi organisera vårdcentraler.

In Swedish primary care patients are registered at health centres where different professions, such as general practitioners (GPs), nurses, assistant nurses, counsellors, physiotherapists, psychologists and biomedical analysts, work. In an international comparison personal physician continuity is low in Sweden. Several governmental inquiries propose that patients register with one GP or a care team. Do Swedish GPs want a personal patient list and how should this best be realised? A web survey was distributed to the members of the Swedish Union of General Practitioners and was answered by 838 GPs. 91% wanted a personal patient list if reasonably sized, the option to limit their list, and shared responsibility for the list with colleagues or a team. To be able to plan the working day themselves and designated time for collegial dialogue was considered essential for increased efficiency, well-being and reduced risk of patients harm due to their doctor's knowledge gaps.

Different antibiotic regimes in men diagnosed with lower urinary tract infection - a retrospective register-based study.

OBJECTIVE: To compare the proportion of therapy failure, recurrence and complications within 30 days after consultation between men diagnosed with lower urinary tract infection (UTI) treated with narrow-spectrum antibiotics (nitrofurantoin or pivmecillinam) and broad-spectrum antibiotics (fluoroquinolones or trimethoprim or trimethoprim/sulfamethoxazole). DESIGN: A retrospective cohort study based on data derived from electronic medical records between January 2012 and December 2015. SETTING: Primary health care and hospital care in five different counties in Sweden. Patients: A total of 16,555 men aged between 18 and 79 years diagnosed with lower UTI. MAIN OUTCOME MEASURES: Treatment with narrow-spectrum antibiotics was compared with broad-spectrum antibiotics regarding therapy failure, recurrence and complications within 30 days. RESULTS: The median age of included men was 65 IQR (51-72) years. Narrow-spectrum antibiotics were prescribed in 8457 (40%) and broad-spectrum antibiotics in 12,667 (60%) cases, respectively. Therapy failure was registered in 192 (0.9%), recurrence in 1277 (6%) and complications in 121 (0.6%) cases. Therapy failure and recurrence were more common in patients treated with narrow-spectrum antibiotics and trimethoprim (p < 0.001), but no such difference could be detected regarding complications. CONCLUSION: There was no difference in incidence of complications within 30 days between men treated with narrow- or broad-spectrum antibiotics. Patients prescribed broad-spectrum antibiotics had lower odds of reconsultation because of therapy failure and recurrence. From current data, treatment with narrow-spectrum antibiotics seems to be an optimal choice regarding preventing complications when treating men with lower UTI. KEY POINTS Complications such as pyelonephritis and sepsis are uncommon in men diagnosed with lower urinary tract infection treated with antibiotics. There was no difference in incidence of complications among men diagnosed with lower urinary tract infection treated with narrow- or broad-spectrum antibiotics. In spite of higher incidence of therapy failure and recurrence, treatment with narrow-spectrum antibiotics seems to be an optimal choice regarding preventing complications when treating men diagnosed with lower UTI.

[Personal physician continuity in primary care associated with fewer emergency room visits]. / Hög personlig läkar­kontinuitet i primärvård förenad med färre besök på akutmottagning - En populationsbaserad studie i Jönköpings sjukvårdsregion.

Overloading of the emergency departments in hospitals is, in Sweden, a common problem that is often blamed on lack of access to primary care.  We have conducted a cross-sectional study comprising more than 40% of the 347 837  inhabitants of Region Jönköping with access to complete individual data on healthcare consumption, personal doctor continuity, socio-economics, and accessibility data for all of the region's health centres. Individuals with high personal continuity at their own health centre had significantly fewer emergency room visits compared to those with the lowest continuity: for younger adults 55% and for elderly 34% fewer emergency room visits. Access to doctor consultations or to counselling nurses in primary care was not associated with a lower number of emergency room visits. Our results show the importance of personal doctor continuity also for the group of younger adults.

[The doctor's personal knowledge of patients saved resources and reduced mortality in an American study. How should a care system in Sweden be designed to get similar effects?] / Läkares personkännedom sparade liv och resurser - Personlig kontinuitet viktig i ett nytt svenskt vårdsystem.

In a recent study of more than 500 000 hospitalisations, doctors with personal knowledge of their patients used less resources, more often discharged them to their own home and their patients had lower mortality. Furthermore, other studies have shown that personal continuity increases patient satisfaction as well as compliance and reduces costs for medical services and visits to emergency services. In a Swedish context we discuss how a combination of organizational factors and personal listing on physicians and continuity of care favour personal knowledge between physician and patient and contribute to a primary care that works well for both the frail elderly and the healthy young.

Antibiotic prescribing in relation to diagnoses and consultation rates in Belgium, the Netherlands and Sweden: use of European quality indicators.

OBJECTIVE: To assess the quality of antibiotic prescribing in primary care in Belgium, the Netherlands and Sweden using European disease-specific antibiotic prescribing quality indicators (APQI) and taking into account the threshold to consult and national guidelines. DESIGN: A retrospective observational database study. SETTING: Routine primary health care registration networks in Belgium, the Netherlands and Sweden. SUBJECTS: All consultations for one of seven acute infections [upper respiratory tract infection (URTI), sinusitis, tonsillitis, otitis media, bronchitis, pneumonia and cystitis] and the antibiotic prescriptions in 2012 corresponding to these diagnoses. MAIN OUTCOME MEASURES: Consultation incidences for these diagnoses and APQI values (a) the percentages of patients receiving an antibiotic per diagnosis, (b) the percentages prescribed first-choice antibiotics and (c) the percentages prescribed quinolones. RESULTS: The consultation incidence for respiratory tract infection was much higher in Belgium than in the Netherlands and Sweden. Most of the prescribing percentage indicators (a) were outside the recommended ranges, with Belgium deviating the most for URTI and bronchitis, Sweden for tonsillitis and the Netherlands for cystitis. The Netherlands and Sweden prescribed the recommended antibiotics (b) to a higher degree and the prescribing of quinolones exceeded the proposed range for most diagnoses (c) in Belgium. The interpretation of APQI was found to be dependent on the consultation incidences. High consultation incidences were associated with high antibiotic prescription rates. Taking into account the recommended treatments from national guidelines improved the results of the APQI values for sinusitis in the Netherlands and cystitis in Sweden. CONCLUSION: Quality assessment using European disease-specific APQI was feasible and their inter-country comparison can identify opportunities for quality improvement. Their interpretation, however, should take consultation incidences and national guidelines into account. Differences in registration quality might limit the comparison of diagnosis-linked data between countries, especially for conditions such as cystitis where patients do not always see a clinician before treatment. Key points The large variation in antibiotic use between European countries points towards quality differences in prescribing in primary care. • The European disease-specific antibiotic prescribing quality indicators (APQI) provide insight into antibiotic prescribing, but need further development, taking into account consultation incidences and country-specific guidelines. • The incidence of consultations for respiratory tract infections was almost twice as high in Belgium compared to the Netherlands and Sweden. • Comparison between countries of diagnosis-linked data were complicated by differences in data collection, especially for urinary tract infections.

Reduction in antibiotic prescribing for respiratory tract infections in Swedish primary care- a retrospective study of electronic patient records.

BACKGROUND: Swedish studies on antibiotic use in primary care have been based on one-week registrations of infections. In order to study adherence to guidelines, analyses based on large databases that provide information on diagnosis linked prescriptions, are needed. This study describes trends in management of infections in Swedish primary care particularly with regards to antibiotic prescribing and adherence to national guidelines. METHODS: A descriptive study of Sweden's largest database regarding diagnosis linked antibiotic prescription data, the Primary care Record of Infections in Sweden (PRIS), for the years 2008, 2010 and 2013. RESULTS: Although the consultation rate for all infections remained around 30% each year, antibiotic prescribing rates decreased significantly over the years from 53.7% in 2008, to 45.5% in 2010, to 38.6% in 2013 (p = .032). The antibiotic prescribing rate for respiratory tract infections (RTIs) decreased from 40.5% in 2008 to 24.9% in 2013 while those for urinary tract infections and skin and soft tissue infections were unchanged. For most RTI diagnoses there was a decrease in prescription rate from 2008 to 2013, particularly for the age group 0-6 years. Phenoxymethylpenicillin (PcV) was the antibiotic most often prescribed, followed by tetracycline. Tonsillitis and acute otitis media were the two RTI diagnoses with the highest number of prescriptions per 1000 patient years (PY). For these diagnoses an increase in adherence to national guidelines was seen, with regards to treatment frequency, choice of antibiotics and use of rapid antigen detection test. The frequency in antibiotic prescribing varied greatly between different Primary Healthcare Centres (PHCCs). CONCLUSION: Falling numbers of consultations and decreased antibiotic prescription rates for RTIs have reduced the antibiotic use in Swedish primary care substantially. Overprescribing of antibiotics could still be suspected due to large variability in prescribing frequency, especially for acute bronchitis and sinusitis. Continuous evaluation of diagnosis linked prescribing data and feedback to doctors is essential in order to achieve a more prudent antibiotic use.

Adherence to guidelines on antibiotic treatment for respiratory tract infections in various categories of physicians: a retrospective cross-sectional study of data from electronic patient records.

OBJECTIVE: To study how prescription patterns concerning respiratory tract infections differ between interns, residents, younger general practitioners (GPs), older GPs and locums. DESIGN: Retrospective study of structured data from electronic patient records. SETTING: Data were obtained from 53 health centres and 3 out-of-hours units in Jönköping County, Sweden, through their common electronic medical record database. PARTICIPANTS: All physicians working in primary care during the 2-year study period (1 November 2010 to 31 October 2012). OUTCOME MEASURES: Physicians' adherence to current guidelines for respiratory tract infections regarding the use of antibiotics. RESULTS: We found considerable differences in prescribing patterns between physician categories. The recommended antibiotic, phenoxymethylpenicillin, was more often prescribed by interns, residents and younger GPs, while older GPs and locums to a higher degree prescribed broad-spectrum antibiotics. The greatest differences were seen when the recommendation in guidelines was to refrain from antibiotics, as for acute bronchitis. Interns and residents most often followed guidelines, while compliance in descending order was: young GPs, older GPs and locums. We also noticed that male doctors were somewhat overall more restrictive with antibiotics than female doctors. CONCLUSIONS: In general, primary care doctors followed national guidelines on choice of antibiotics when treating respiratory tract infections in children but to a lesser degree when treating adults. Refraining from antibiotics seems harder. Adherence to national guidelines could be improved, especially for acute bronchitis and pneumonia. This was especially true for older GPs and locums whose prescription patterns were distant from the prevailing guidelines.

Cubic and sponge phases in ether lipid-solvent-water ternary systems: phase behavior and NMR characterization.

The phase behavior of 1-glyceryl monoleyl ether (GME) in mixtures of water and the solvents 1,5-pentanediol (POL) or N-methyl-2-pyrrolidone (NMP) was investigated by ocular inspection, polarization microscopy, and small-angle X-ray diffraction (SAXD). Phase diagrams were constructed based on analyses of more than 200 samples prepared using the two different solvents at 20 °C. The inverse hexagonal phase formed by GME in excess of water was transformed into the cubic and sponge phase with the increasing amount of each solvent. Particularly POL allowed for the formation of an extended sponge phase area in the phase diagram, comprising up to 70% POL-water mixture. The phase behavior using NMP was found to be similar to the earlier investigated solvent propylene glycol. The extended sponge phase for the POL system was attributed to POLs strong surface/interfacial activity with the potential to stabilize the polar/apolar interface of the sponge phase. The cubic and sponge phases formed using POL were further studied by NMR in order to measure the partitioning of POL between the lipid and aqueous domains of the phases. The domain partition coefficient K (lipid domain/aqueous domain) for POL in cubic and sponge phases was found to be 0.78 ± 0.14 and constant for the two phases.

In vivo study of an instantly formed lipid-water cubic phase formulation for efficient topical delivery of aminolevulinic acid and methyl-aminolevulinate.

We demonstrate a rapidly formed cubic liquid crystalline phase, i.e. typically 1g cubic phase in less than 1 min confirmed by X-ray diffraction, consisting of an ether lipid, 1-glyceryl monooleyl ether (GME), an aprotic solvent (propylene glycol or pentane-1,5-diol) and water. The efficacy of the cubic formulation was tested in vivo by administrating formulations containing 3% (w/w) of the HCl salts of δ-aminolevulinic acid (ALA) or methylaminolevulinate (MAL) to hairless mice. The endogenous formation of protoporphyrin IX (PpIX) was monitored spectrophotometrically as a marker for cellular uptake of active compound. As reference, a commercial product containing 16% (w/w) MAL in an oil-in-water emulsion (Metvix(®)), and a cubic phase based on an ester lipid (glyceryl monooleate, GMO), previously shown to facilitate topical delivery of both ALA and MAL, were applied. It was found that in general the cubic phases gave rise to higher fluorescence levels than the mice exposed to the commercial product. The instantly formed cubic formulations based on GME demonstrated the same efficiency as the GMO based formulations. The results imply that instantly formed cubic formulations opens up new opportunities, particularly for transdermal drug delivery of substances subject to stability problems in, e.g. aqueous environments.

Factors influencing the prescription of drugs of different price levels.

PURPOSE: Socioeconomic factors have been suggested to influence the prescribing of newer and more expensive drugs. In the present study, individual and health care provider factors were studied in relation to the prevalence of differently priced drugs. METHODS: Register data for dispensed drugs were retrieved for 18 486 individuals in a county council in Sweden. The prevalence of dispensed drugs was combined with data for the individual's gender, age, education, income, foreign background, and type of caregiver. For each of the diagnostic groups (chronic obstructive pulmonary disease [COPD], depression, diabetes, and osteoporosis), selected drugs were dichotomized into cost categories, lower and higher price levels. Univariate and multivariate logistic regressions were performed using cost category as the dependent variable and the individual and provider factors as independent variables. RESULTS: In all four diagnostic groups, differences were observed in the prescription of drugs of lower and higher price levels with regard to the different factors studied. Age and gender affected the prescription of drugs of lower and higher price levels more generally, except for gender in the osteoporosis group. Income, education, foreign background, and type of caregiver affected prescribing patterns but in different ways for the different diagnostic groups. CONCLUSIONS: Certain individual and provider factors appear to influence the prescribing of drugs of different price levels. Because the average price for the cheaper drugs versus more costly drugs in each diagnostic group was between 19% and 69%, there is a risk that factors other than medical needs are influencing the choice of drug.

How does comorbidity influence healthcare costs? A population-based cross-sectional study of depression, back pain and osteoarthritis.

OBJECTIVES: To analyse how comorbidity among patients with back pain, depression and osteoarthritis influences healthcare costs per patient. A special focus was made on the distribution of costs for primary healthcare compared with specialist care, hospital care and drugs. DESIGN: Population-based cross-sectional study. SETTING: The County of Östergötland, Sweden. PATIENTS: Data on diagnoses and healthcare costs for all 266 354 individuals between 20 and 75 years of age, who were residents of the County of Östergötland, Sweden, in the year 2006, were extracted from the local healthcare register and the national register of drug prescriptions. MAIN OUTCOME MEASURES: The effects of comorbidity on healthcare costs were estimated as interactions in regression models that also included age, sex, number of other health conditions and education. RESULTS: The largest diagnosed group was back pain (11 178 patients) followed by depression (7412 patients) and osteoarthritis (5174 patients). The largest comorbidity subgroup was the combination of back pain and depression (772 patients), followed by the combination of back pain and osteoarthritis (527 patients) and the combination of depression and osteoarthritis (206 patients). For patients having both a depression diagnosis and a back pain diagnosis, there was a significant negative interaction effect on total healthcare costs. The average healthcare costs among patients with depression and back pain was SEK 11 806 lower for a patient with both diagnoses. In this comorbidity group, there were tendencies of a positive interaction for general practitioner visits and negative interactions for all other visits and hospital days. Small or no interactions at all were seen between depression diagnoses and osteoarthritis diagnoses. CONCLUSIONS: A small increase in primary healthcare visits in comorbid back pain and depression patients was accompanied with a substantial reduction in total healthcare costs and in hospital costs. Our results can be of value in analysing the cost effects of comorbidity and how the coordination of primary and secondary care may have an impact on healthcare costs.

Membrane protein crystallization from lipidic phases.

Membrane protein structural biology is enjoying a steady acceleration in the rate of success. Nevertheless, numerous membrane protein targets are resistant to the traditional approach of directly crystallizing detergent solubilized and purified protein and the 'niche market' of lipidic phase crystallization is emerging as a powerful complement. These approaches, including lipidic cubic phase, lipidic sponge phase, and bicelle crystallization methods, all immerse purified membrane protein within a lipid rich matrix before crystallization. This environment is hypothesized to contribute to the protein's long-term structural stability and thereby favor crystallization. Spectacular recent successes include the high-resolution structures of the beta(2)-adrenergic G-protein-coupled receptor, the A(2A) adenosine G-protein-coupled receptor, and the mitochondrial voltage dependent anion channel. In combination with technical innovations aiming to popularize these methods, lipidic phase crystallization approaches can be expected to deliver an increasing scientific impact as the field develops.
