Preventive effect of methenamine in women with recurrent urinary tract infections - a case-control study

BACKGROUND

Urinary tract infection (UTI) is the most common bacterial infection in women. In Norwegian general practice, methenamine has been prescribed for many years as long-term prevention and accounted for 20% of the total antibiotic prescribing in 2015, as measured in defined daily dosages (DDDs). The efficacy of methenamine is unknown. If shown to be effective, this drug may become an important preventive against UTI.

OBJECTIVE

To examine whether methenamine is preventive against recurrent UTI in women.

DESIGN

Data for all antibiotics used for UTIs dispensed from all pharmacies from 2005 to 2015 were collected from the Norwegian prescription database (NorPD).

SUBJECTS

Women aged ≥ 40 years with recurrent UTI, defined as ≥3 courses of UTI antibiotic/year, were included.

MAIN OUTCOME MEASURES

Patients using methenamine (cases) and those not using methenamine (controls) were compared. The numbers of UTI prescriptions during the 2 years before and after inclusion were analysed. Results: The yearly prevalence for recurrent UTI was 2.4% in women ≥ 40 years. The change in antibiotic use from 2 years before to 2 years after inclusion in the study differed significantly between groups: 44.6 and 34.9% reductions in the number of antibiotic prescriptions for UTI in the methenamine and control groups, respectively. The decrease in UTI antibiotic prescriptions (58.9%) was greater in patients with a higher consumption of antibiotics before starting methenamine.

CONCLUSIONS

Methenamine seems to be effective against recurrent UTI over the time span studied. The effect seems to be greater in patients with the highest number of recurrent UTIs. Key pointsMethenamine has been used for many years for prevention of recurrent UTI, but no studies have demonstrated a significant preventive effect of long time use.This study shows that methenamine seems to be effective for prevention in patients having recurrent UTI over 2 years or more.The effect seems to be larger in patients with a high number of UTIs over 2 years.

The Norwegian PraksisNett: a nationwide practice-based research network with a novel IT infrastructure

PURPOSE

Clinical research in primary care is relatively scarce. Practice-based research networks (PBRNs) are research infrastructures to overcome hurdles associated with conducting studies in primary care. In Norway, almost all 5.4 million inhabitants have access to a general practitioner (GP) through a patient-list system. This gives opportunity for a PBRN with reliable information about the general population. The aim of the current paper is to describe the establishment, organization and function of PraksisNett (the Norwegian Primary Care Research Network).

MATERIALS AND METHODS

We describe the development, funding and logistics of PraksisNett as a nationwide PBRN.

RESULTS

PraksisNett received funding from the Research Council of Norway for an establishment period of five years (2018-2022). It is comprised of two parts; a human infrastructure (employees, including academic GPs) organized as four regional nodes and a coordinating node and an IT infrastructure comprised by the Snow system in conjunction with the Medrave M4 system. The core of the infrastructure is the 92 general practices that are contractually linked to PraksisNett. These include 492 GPs, serving almost 520,000 patients. Practices were recruited during 2019-2020 and comprise a representative mix of rural and urban settings spread throughout all regions of Norway.

CONCLUSION

Norway has established a nationwide PBRN to reduce hurdles for conducting clinical studies in primary care. Improved infrastructure for clinical studies in primary care is expected to increase the attractiveness for studies on the management of disorders and diseases in primary care and facilitate international research collaboration. This will benefit both patients, GPs and society in terms of improved quality of care.Key pointsPractice-based research networks (PBRNs) are research infrastructures to overcome hurdles associated with conducting studies in primary careImproved infrastructure for clinical studies in primary care is expected to increase the attractiveness for studies on the management of disorders and diseases in primary care and facilitate international research collaborationWe describe PraksisNett, a Norwegian PBRN consisting of 92 general practices including 492 GPs, serving almost 520,000 patientsAn advanced and secure IT infrastructure connects the general practices to PraksisNett and makes it possible to identify and recruit patients in a novel way, as well as reuse clinical dataPraksisNett will benefit both patients, GPs and society in terms of improved quality of careThis paper may inform and inspire initiatives to establish PBRNs elsewhere.

Detecting young people with mental disorders: a cluster-randomised trial of multidisciplinary health teams at the GP office

BACKGROUND

Young people with mental health challenges present a major global challenge. More than half of adults with mental disorders experience their onset before age 14, but early detection and intervention may change this course. Shared care with mental health professionals in general practitioner (GP) offices has demonstrated its potential for improvement in these conditions.

AIM

To investigate whether shared care with mental health professionals in GP offices increases the detection of youth's mental health disorders and is associated with a decrease in use of unspecified symptom diagnoses, as a whole and stratified by patient and physician gender and age, and type of consulting physician.

DESIGN AND SETTING

This was a stratified cluster-randomised controlled trial with data extraction from electronic records. Two GP offices were recruited from each of three boroughs. Each borough had 3-8 GP offices. One GP office was randomised to the intervention group and the other to the control group.

METHOD

We used generalised linear mixed models to assess whether the intervention helped GPs identify more International Classification of Primary Care 2 diagnoses of depression, anxiety and unspecified symptoms in youth.

RESULTS

Over a 18-month period between between 2015 and 2017, the intervention helped GPs identify more youth with anxiety (p=0.002 for interaction), but not depression. The increase was most significant among the patients' regular GPs, less when patients met other GPs and least among external substitute physicians. The frequency of diagnoses with unspecified symptoms decreased in the intervention arm.

CONCLUSION

Shared care with mental health professionals located in GP office contributed to increased detection of youth with anxiety symptoms. The increase was most prominent when the primary care physician was the patient's regular GP. GPs need to pay greater attention to detecting anxiety in youth and embrace shared care models, thereby contributing to reduced mental health disorders in this age group.

Physician factors associated with increased risk for complaints in primary care emergency services: a case - control study

BACKGROUND

Patient safety incidents defined as any unintended or unexpected incident that could have or were judged to have led to patient harm, are reported as relatively common. In this study patient complaints have been used as an indicator to uncover the occurrence of patient safety incidents in primary care emergency units (PCEUs) in Norway.

METHODS

Ten PCEUs in major cities and rural parts of Norway participated. These units cover one third of the Norwegian population. A case-control design was applied. The case was the physician that evoked a complaint. The controls were three randomly chosen physicians from the same PCEU as the physician having evoked the complaint. The following variables regarding the physicians were chosen: gender, citizenship at, and years after authorization as physician, and specialty in general practice. The magnitude of patient contact was defined as the workload at the PCEU. The physicians' characteristics and workload were extracted from the medical records from the fourteen-day period prior to the consultation that elicited the complaint. The rest of the variables were then obtained from the Norwegian physician position register. Logistic regression was used to estimate odds ratio for complaints both unadjusted and adjusted for the independent variables. The data were analyzed using SPSS (Version25) and STATA.

RESULTS

A total of 78 cases and 217 controls were included during 18 months (September 1st 2015 till March 1st 2017). The risk of evoking a complaint was significantly higher for physicians without specialty in general practice, and lower for those with medium low and medium high workload compared to physicians with no duty during the fourteen-day period prior to the index consultation. The limited strength of the study did not make it possible to assess any correlation between workload and the other variables (physician's gender, seniority and citizenship at time of authorization).

CONCLUSIONS

Continuous medical training and achieving the specialty in general practice were decisively associated with a reduced risk for complaints in primary care emergency services. Future research should focus on elements promoting quality of care such as continuing education, duty rosters and other structural and organizational factors.

Exploring why patients with cancer consult GPs: a 1-year data extraction

BACKGROUND

Survival rates of patients with cancer are increasing owing to improvements in diagnostics and therapies. The traditional hospital-based follow-up model faces challenges because of the consequent increasing workload, and it has been suggested that selected patients with cancer could be followed up by GPs.The hypothesis of the study was that, regardless of the hospital-based follow-up care, GPs see their patients with cancer both for cancer-related problems as well as for other reasons. Thus, a formalised follow-up by GPs would not mean too large a change in GPs' workloads.

AIM

To explore to what extent patients with cancer consult their GPs, and for what reasons.

DESIGN & SETTING

A 1-year explorative study was undertaken, based on data from 91 Norwegian GPs from 2016-2017.

METHOD

The data were electronically extracted from GPs' electronic medical records (EMR).

RESULTS

Data were collected from 91 GPs. There were 11 074 consultations in total, generated by 1932 patients with cancer. The mean consultation rate was higher among the patients with cancer compared with Norwegian patients in general. In one-third of the consultations, cancer was the main diagnosis. Apart from cancer, cardiovascular and musculoskeletal diagnoses were common. Patients with cancer who had multiple diagnoses or psychological diagnoses did not consult their GP significantly more often than patients with cancer without such comorbidity.

CONCLUSION

This study confirms that patients with cancer consult their GP more often than other patients, both for cancer-related reasons and for various comorbidities. A formalised follow-up by GPs would probably be feasible, and GPs should prepare for this responsibility.

Relationship between Maternal and First Year of Life Dispensations of Antibiotics and Antiasthmatics

Antibiotics are the most frequent prescription drugs used by pregnant women. Our objective was to investigate if the dispensation of antibiotics and antiasthmatics in children less than 1 year of age is associated with prenatal antibiotic exposure. A secondary aim was to explore the incidence of dispensed antibiotics in pregnancy and dispensed antibiotics and antiasthmatics in children. We conducted an observational study using the Peer Academic Detailing study database to select patients eligible for match in the Medical Birth Registry of Norway, a total of 7747 mother-and-child pairs. Details on antibiotic and antiasthmatic pharmacy dispensations were obtained from the Norwegian Prescription Database. One quarter (1948 of 7747) of the mothers in the study had been dispensed antibiotics during pregnancy. In their first year of life, 17% (1289) of the children had had an antibiotic dispensation, 23% (1747) an antiasthmatic dispensation, and 8% (619) of the children had had both. We found a significant association between dispensed antibiotics in pregnancy and dispensed antibiotics to the child during their first year of life; OR = 1.16 (95% CI: 1.002⁻1.351). The association was stronger when the mothers were dispensed antibiotics at all, independent of the pregnancy period; OR = 1.60 (95% CI: 1.32⁻1.94). We conclude that the probability for dispensation of antibiotics was increased in children when mothers were dispensed antibiotics, independent of pregnancy. Diagnostic challenges in the very young and parental doctor-seeking behavior may, at least in part, contribute to the association between dispensations in mothers and children below the age of one year.

Potentially Inappropriate Prescribing to Older Patients: Criteria, Prevalence and an Intervention to Reduce It: The Prescription Peer Academic Detailing (Rx-PAD) Study - A Cluster-Randomized, Educational Intervention in Norwegian General Practice

Potentially inappropriate prescriptions (PIP) is drug treatment, which in general, at the group level for a median/mean patient, can be considered unfavourable meaning that the risks commonly may outweigh the benefits. This MiniReview reports and discusses the main findings in a large cluster-randomized educational intervention in Norwegian general practice, aimed at reducing the prevalence of PIPs to patients ≥70 years (The Rx-PAD study). Targets for the intervention were general practitioners (GPs) in continuing medical education (CME) groups receiving educational outreach visits (i.e. peer academic detailing). A Delphi consensus process, with a panel of medical experts, was undertaken to elaborate a list of explicit criteria defining PIPs for patients ≥70 years in general practice. Agreement was achieved for 36 explicit PIP criteria, the so-called Norwegian General Practice (NorGeP) criteria. Using a selection (n = 24) of these criteria during a 1-year baseline period on the prescribing practice of 454 GPs (i.e. those enrolled to participate in the intervention trial), we found a prevalence rate of 24.7 PIPs per 100 patients ≥70 years per year. In the Rx-PAD study, 449 GPs completed an educational intervention (96.6% of the included GPs), 250 in the intervention group and 199 in the control arm. Following the intervention, PIPs were reduced by 13% (95% CI 8.6-17.3), and the number of patients who were no longer exposed to one or more PIPs was reduced by 1173 (8.1%). The GPs who responded most strongly to the educational intervention were the oldest GPs (57-68 years), and these were the GPs with the highest prevalence of PIPs at baseline before the intervention.

General practitioners' prescriptions of benzodiazepines, Z-hypnotics and opioid analgesics for elderly patients during direct and indirect contacts. A cross-sectional, observational study

OBJECTIVE

To describe Norwegian general practitioners' (GPs') prescription patterns of benzodiazepines, Z-hypnotics and opioid analgesics (BZO-drugs) to elderly (≥70 years) patients.

DESIGN, SUBJECTS AND SETTING

Cross sectional, observational study. Contact- and prescription data from 148 Norwegian GPs, issued for elderly patients during eight months in 2008. GP-patient contacts were categorized as direct contacts (DC: face-to-face consultations) or indirect contacts (IC: via third party, phone or mail). Explanatory variables were characteristics linked to the GPs, patients, and practices. During analyses, GPs' number of listed patients, share of which for elderly patients, and total number of patient consultations during the period (proxy for practice activity), were categorized in quintiles (Q1-5) by number of GPs.

MAIN OUTCOME MEASURES

Number of BZO-drug prescriptions and quantities issued during direct- and indirect GP-patient contacts.

RESULTS

In total, 62% of BZO-prescriptions were issued during ICs. Of all prescriptions, 66% were large quantum packages (50 tablets or more), 62% out of which were prescribed during ICs. During the study period, 50% of the patients received repeat prescriptions. Prescribing during ICs was associated with low over all practice activity (Q1) and many (Q5) older patients on the GP's lists.

CONCLUSION

GPs' BZO-drug prescribing to elderly occur more frequently during ICs than within DCs, and are more commonly issued as large quantity packages. This indicates that regular- or long-term use among elderly is common, contrasting with previous and current national guidelines, which recommend regular clinical assessments and short time or intermittent use of BZO-drugs. Key Points GPs frequently prescribe benzodiazepines, Z-hypnotics and opioid (BZO) drugs for elderly people. BZO-drugs are frequently issued during indirect GP-patient contacts and in relatively large quantities, indicating regular or long-term use. GPs' BZO-drug prescribing patterns contrast with national guidelines recommending clinical assessment and short time or intermittent use of BZO-drugs.

Potentially inappropriate medication use in nursing homes: an observational study using the NORGEP-NH criteria

Background

Frail residents in the nursing home sector call for extra care in prescribing. The Norwegian General Practice Nursing Home (NORGEP-NH) list of 34 explicit criteria for potentially inappropriate medication use in nursing homes was developed explicitly for this population. The aim of this study was to employ the NORGEP-NH Criteria to study the extent of potentially inappropriate medication use among nursing home residents and explore possible associated factors.

Methods

Cross-sectional observational pharmacoepidemiological study from residents in nursing homes in the county of Vestfold, Norway. Data collected 2009–11 included residents’ demographic and clinical status and all medications, regular and on demand.

Results

881 patients from 30 institutions (mean 85.9 years, 68.6% female), were included. According to NORGEP-NH, 43.8% were prescribed at least one potentially inappropriate regular medication, and 9.9% regularly received three or more potentially inappropriate medications. When also including a) the NORGEP-NH Deprescribing Criteria and b) including drugs prescribed for use as needed, 92.7% of all residents received medication that needs particular surveillance according to the NORGEP-NH. 69.7% of the nursing home residents used at least one psychotropic drug regularly. Female residents received more often than males at least one potentially inappropriate regular medication (OR 1.60, p=0.007). Regarding the prescription of three or more concomitant psychotropic medications, odds ratio for females was 1.79 (p=0.03) compared to males. Residents with the best performance in activities of daily living, and residents residing in long-term wards, had higher risk of using three or more psychotropic drugs. Use of multiple psychoactive drugs increased the risk of falls in the course of an acute episode of infection or dehydration (odds ratio 1.70, p=0.009).

Conclusions

Prevalence of potentially inappropriate medications in nursing homes according to the NORGEP-NH was extensive, and especially the use of multiple psychotropic drugs. The high prevalence found in this study shows that there is a need for higher awareness of medication use and side effects in the elderly population.

A structured training program for health workers in intravenous treatment with fluids and antibiotics in nursing homes: A modified stepped-wedge cluster-randomised trial to reduce hospital admissions

Objectives

Hospitalization is potentially detrimental to nursing home patients and resource demanding for the specialist health care. This study assessed if a brief training program in administrating intravenous fluids and antibiotics in nursing homes could reduce hospital transfers and ensure high quality care locally.

Design

A pragmatic and modified cluster randomized stepped-wedge trial with randomization on nursing home level.

Participants

330 cases in 296 nursing home residents from 30 nursing homes were included. Cases were patients provided intravenous antibiotics or intravenous fluids, in nursing home or hospital. Primary outcome was localization of treatment, secondary outcomes were number of days treated, days of hospitalization among admitted patients, type of antibiotics used and 30-day mortality.

Intervention

The nursing homes sequentially received a one-day educational program for the health workers including theory and practical training in intravenous treatment of dehydration and infection, run by two skilled nurses. After completing the training program, the nursing homes had competence to provide intravenous treatment locally.

Results

The intervention had a highly significant effect on treatment in nursing homes (OR 8.35, 2.08 to 33.6; P<0.01, or RR 2.23, 1.48 to 2.56). The number treated in nursing homes was stable over time; the number treated in hospital gradually decreased (chi square for trend P< 0.001).

Among patients receiving intravenous antibiotics in the nursing homes, 50 (46%) died within 30 days, compared to 30 (36%) treated in the hospital (P = 0.19). Among patients receiving intravenous fluids locally, 21 (19%) died within 30 days, compared to 2 (8%) in the hospital group (P = 0.34). Mortality was associated with reduced consciousness and elevated c-reactive protein.

Conclusions

A brief educational program delivered to nursing home personnel was feasible and effective in reducing acute hospital admissions from nursing homes for treatment of dehydration and infections.

Antibiotic prescribing for acute respiratory tract infections in Norwegian primary care out-of-hours service

PURPOSE

To examine factors correlating with antibiotic prescribing for acute respiratory tract infections (ARTIs) in Norwegian primary care out-of-hours service.

MATERIALS AND METHODS

Retrospective data analysis for the year 2014 in two out-of-hours primary care units located in the towns of Hamar and Tønsberg in Norway, analysing type and frequency of different antibiotics prescribed by 117 medical doctors for ARTIs, and factors correlating with these.

RESULTS

The 117 doctors in two out-of-hours units diagnosed 6757 cases of ARTIs. 2310 (34.2%) of these resulted in an antibiotic prescription, where of 1615 (69.9%) were penicillin V (PcV). Tonsillitis and sinusitis were the two ARTI diagnoses with the highest antibiotic prescription rate. The antibiotic prescription rate increased successively with increasing activity level, measured as shorter median duration of consultations per session, from 28.7% (reference) in the least busy quintile of sessions to 36.6% (OR: 1.38 (95% CI =1.06-1.80)) in the busiest quintile of sessions. Prescribing of broad-spectrum antibiotics was not correlated with median duration of consultations per session. Female doctors had an OR of 0.61 (0.40-0.92) of a broad-spectrum antibiotic prescription compared to their male colleagues.

CONCLUSIONS

Antibiotic prescribing for ARTIs in the primary care out-of-hours services investigated is at the same level as in Norwegian general practice, but with a higher prescription rate of PcV. Antibiotic prescribing increases on busy sessions, measured as median duration of consultations per session. The work frame in primary care out-of-hours service might influence the quality of clinical decisions.

Peer academic detailing on use of antibiotics in acute respiratory tract infections. A controlled study in an urban Norwegian out-of-hours service

OBJECTIVE

To analyse if peer academic detailing by experienced general practitioners (GPs) could be a useful way to change Medical Doctors, (MDs) prescription of antibiotics for acute respiratory tract infections (ARTIs) in out-of-hours service.

METHOD

An educational Intervention study based on prescription data among MDs working in an out-of-hours service from June 2006 through October 2008. Specially trained GPs lectured a peer educational program (3 × 45 minutes) about use of antibiotics for ARTIs according to national recommendations.

OUTCOME MEASURES

The type and frequency of antibiotics prescribed for different ARTIs before and after intervention comparing the intervention group with the control group.

SUBJECTS

22 MDs in the intervention group and 31 MDs in the control group.

RESULTS

The intervention group showed an overall statistically significantly absolute increase in the use of penicillin V (Penicillin V) of 9.8% (95% CI: 2.3%-17.4% p < 0.05), and similarly an statistically significantly absolute decrease in the use of macrolides and lincosamides of 8.8% (95% CI: 2.6%-14.9.2% p < 0.05) for all diagnoses. For subgroups of ARTIs we found a significant increase in the use of Penicillin V for acute otitis media, sinusitis, pneumonia and upper ARTIs. There was no significant changes in total prescription rates in the two groups. 41% of all consultations with respiratory tract infections resulted in antibiotic prescription.

CONCLUSIONS

Using trained GPs to give peer academic detailing to colleagues in combination with open discussion on prescription, showed a significant change in prescription of antibiotics towards national guidelines. Key points Phenoxymethylpenicillin is the first choice for the most of respiratory tract infections when indicated. Despite the guidelines for the choice of antibiotics in Norway, general practitioners' choice often differs from these. We showed that a session of three times 45 min of peer academic detailing changed significantly the choice of antibiotics towards the National Guidelines in an urban Norwegian out-of-hours service.

Improving antibiotic prescribing in acute respiratory tract infections: cluster randomised trial from Norwegian general practice (prescription peer academic detailing (Rx-PAD) study)

OBJECTIVE

To assess the effects of a multifaceted educational intervention in Norwegian general practice aiming to reduce antibiotic prescription rates for acute respiratory tract infections and to reduce the use of broad spectrum antibiotics.

DESIGN

Cluster randomised controlled study.

SETTING

Existing continuing medical education groups were recruited and randomised to intervention or control.

PARTICIPANTS

79 groups, comprising 382 general practitioners, completed the interventions and data extractions.

INTERVENTIONS

The intervention groups had two visits by peer academic detailers, the first presenting the national clinical guidelines for antibiotic use and recent research evidence on acute respiratory tract infections, the second based on feedback reports on each general practitioner's antibiotic prescribing profile from the preceding year. Regional one day seminars were arranged as a supplement. The control arm received a different intervention targeting prescribing practice for older patients.

MAIN OUTCOME MEASURES

Prescription rates and proportion of non-penicillin V antibiotics prescribed at the group level before and after the intervention, compared with corresponding data from the controls.

RESULTS

In an adjusted, multilevel model, the effect of the intervention on the 39 intervention groups (183 general practitioners) was a reduction (odds ratio 0.72, 95% confidence interval 0.61 to 0.84) in prescribing of antibiotics for acute respiratory tract infections compared with the controls (40 continuing medical education groups with 199 general practitioners). A corresponding reduction was seen in the odds (0.64, 0.49 to 0.82) for prescribing a non-penicillin V antibiotic when an antibiotic was issued. Prescriptions per 1000 listed patients increased from 80.3 to 84.6 in the intervention arm and from 80.9 to 89.0 in the control arm, but this reflects a greater incidence of infections (particularly pneumonia) that needed treating in the intervention arm.

CONCLUSIONS

The intervention led to improved antibiotic prescribing for respiratory tract infections in a representative sample of Norwegian general practitioners, and the courses were feasible to the general practitioners.

TRIAL REGISTRATION

Are children carrying the burden of broad-spectrum antibiotics in general practice? Prescription pattern for paediatric outpatients with respiratory tract infections in Norway

OBJECTIVES

To investigate the antibiotic prescription pattern and factors that influence the physicians' choice of antibiotic.

DESIGN

Observational study.

SETTING

Primary healthcare in Norway, December 2004 through November 2005.

PARTICIPANTS

426 general practitioners, GPs, in Norway, giving 24 888 respiratory tract infection episodes with 19 938 children aged 0-6 years.

OUTCOME MEASURES

Assess antibiotic prescription details and patient and GP characteristics associated with broad-spectrum and narrow-spectrum antibiotic use.

RESULTS

Of the 24 888 episodes in the study, 26.2% (95% CI 25.7% to 26.8%) included an antibiotic prescription. Penicillin V accounted for 42% and macrolide antibiotics for 30%. The prescription rate varied among the physicians, with a mean of 25.5% (95% CI 24.2% to 26.7%). Acute tonsillitis gave the highest odds for a prescription, OR 33.6 (95% CI 25.7% to 43.9%), compared to 'acute respiratory tract infections and symptoms' as a reference group. GPs with a prescription rate of 33.3% or higher had the larger probability for broad-spectrum antibiotic prescriptions, OR 3.33 (95% CI 2.01% to 5.54%). Antibiotic prescriptions increased with increasing patient age.

CONCLUSIONS

We found a low antibiotic prescription rate for childhood respiratory tract infections. However, our figures indicate an overuse of macrolide antibiotics and penicillins with extended spectrum, more so than in the corresponding study including the adult population. Palatability of antibiotic suspensions and other administrative challenges affect medication compliance in children. To help combat antibiotic resistance, guidelines need to be followed, in particular for our youngest patients. TRIAL REGISTRATION NUMBER (CLINICALTRIALS.ORG): NCT00272155.

[Do general practitioners follow the national guidelines for treating urinary tract infections with antibiotics?]

BACKGROUND

Incorrect use of antibiotics is a major public health concern both nationally and globally due to the development of antibiotic resistance. The goal of this study was to see if prescription of antibiotics for urinary tract infections in general practice was in accordance with national guidelines.

MATERIAL AND METHODS

We combined two sets of data from February and March 2003: prescriptions of antibiotics redeemed in pharmacies, and electronic billing cards collected from the National Insurance Agency from 145 general practitioners in Vestfold county. We analysed all consultations related to urinary tract problems, and we found which antibiotics had been prescribed and for how long. The treatment was then compared with the national guidelines. A logistic regression analysis identified factors associated with adequate treatment length.

RESULTS

Trimetoprime and mecillinam were most frequently prescribed to both genders. Sixty-nine (6 %) of the total 1,102 prescriptions were quinolones. A total of 271 (32 %) of 847 patients who were prescribed antibiotics for cystitis did not get treatment of sufficient length. Female and young patients were more often given the correct duration of treatment. Doctors with 1,000-1,500 patients more frequently prescribed sufficiently long treatment compared to other physicians. Six patients (0.5 %) were prescribed another antibiotic between two and 14 days after the first prescription.

CONCLUSION

The choice of antibiotics conformed well with national guidelines, but the duration of the treatment was often too short. In spite of this, only 0.5 % showed signs of relapse. A number of factors associated with adequate treatment length were identified. The empirical use of furadantin can be increased.

Do general practitioners' consultation rates influence their prescribing patterns of antibiotics for acute respiratory tract infections?

OBJECTIVES

To examine general practitioners' (GPs') antibiotic prescribing patterns for acute respiratory tract infections (ARTIs) as compared with national guidelines. We also wanted to explore possible predictors of antibiotic prescription patterns.

METHODS

Observational study based on prescription data from 440 Norwegian GPs in December 2004 through to November 2005. Outcome measures were the type and frequency of antibiotic prescriptions for various ARTI diagnoses, with patients' and GPs' characteristics as explanatory variables.

RESULTS

In the study period, the 440 GPs treated a total of 142 900 ARTI episodes. In 33.5% [95% confidence interval (CI): 31.9%-35.1%] of these episodes an antibiotic was issued, of which penicillin V (pcV) accounted for 41.2% (95% CI: 37.4%-44.9%). GPs with a high number of total annual encounters had higher antibiotic prescription rates for ARTIs and used more non-pcV antibiotics compared with GPs with fewer annual patient encounters. GPs in the highest quintile with respect to the total annual encounter rate had 1.6 times the odds of prescribing antibiotics compared with GPs in the lowest quintile. Correspondingly, the odds of choosing a non-pcV antibiotic were 2.8 times higher in the top quintile of GPs compared with GPs in the bottom quintile with respect to antibiotic prescription rates.

CONCLUSIONS

ARTIs are frequently treated with antibiotics and often with broader spectrum agents than pcV, which is the recommended first-line antibiotic in the Norwegian guidelines. GPs with a high practice activity are, in general, more liberal with respect to the prescription of antibiotics for ARTIs, and the higher the antibiotic prescription rate, the larger the share of non-pcV agents.

Vitamin D status in patients with musculoskeletal pain, fatigue and headache: a cross-sectional descriptive study in a multi-ethnic general practice in Norway

OBJECTIVE

To investigate vitamin D levels in patients with non-specific musculoskeletal pain, headache, and fatigue.

DESIGN

A cross-sectional descriptive study.

SETTING

A health center in Oslo, Norway, with a multi-ethnic population.

SUBJECTS

A total of 572 patients referred by a general practitioner (GP) for an examination of hypovitaminosis D who reported musculoskeletal pain, headache, or fatigue. The patients' native countries were: Norway (n = 249), Europe, America, and South-East Asia (n = 83), and the Middle East, Africa, and South Asia (n = 240). Both genders and all ages were included.

MAIN OUTCOME MEASURES

Vitamin D levels (25-hydroxyvitamin D) in nmol/L.

RESULTS

Hypovitaminosis D (25-hydroxyvitamin D < 50 nmol/L) was found in 58% of patients. One-third of ethnic Norwegians had hypovitaminosis D, while 83% of patients from the Middle East, Africa, and South Asia had hypovitaminosis D with minimal seasonal variation of levels. One in two women from these countries had a vitamin D level below 25 nmol/L. Mean vitamin D level was lower in patients with headaches compared with patients with other symptoms. Some 15% of patients with low (< 50 nmol/L) vitamin D levels reported headaches, compared with 5% of those with normal vitamin D levels.

CONCLUSION

Our study shows a high prevalence of hypovitaminosis D in patients with non-specific musculoskeletal pain, headache, or fatigue for whom the GP had suspected a low vitamin D level. Hypovitaminosis D was not restricted to immigrant patients. These results indicate that GPs should maintain awareness of hypovitaminosis D and refer patients who report headaches, fatigue, and musculoskeletal pain with minimal sun exposure and a low dietary vitamin D intake for assessment.

GPs' antibiotic prescription patterns for respiratory tract infections--still room for improvement

OBJECTIVE

Inappropriate use of antibiotics is associated with increased antibiotic resistance in the community. About 90% of all antibiotic prescriptions in Norway are issued by general practitioners and in 60% issued for respiratory tract infections. The article describes and analyses antibiotic prescription patterns by general practitioners in Vestfold, Norway.

DESIGN

Prospective cohort study.

SUBJECTS

A total of 145 list-holding general practitioners in Vestfold, Norway in February to March 2003.

METHODS

Merging of two electronic administrative data sets: antibiotic prescriptions dispensed in pharmacies and general practitioners' electronic bills from the National Insurance Agency.

MAIN OUTCOME MEASURES

Proportion and type of antibiotic prescribed for different respiratory tract infectious diagnoses.

RESULTS

We found large variations among general practitioners' antibiotic prescription habits. In 27% of consultations with RTI diagnoses, an antibiotic was prescribed; 37% were for Penicillin V and 28% for a macrolide. Quinolones and cephalosporins were only rarely prescribed. In a logistic regression analysis the following factors were independently associated with antibiotic prescription rate: type of infection, type of contact, being a general practitioner specialist, and years since medical exam. In another logistic regression analysis the following factors were independently associated with broad-spectrum antibiotic prescription: type of infection, age of patient, type of contact, being a specialist, length of list, and being a high prescriber of antibiotics.

CONCLUSION

The variation in proportion of total antibiotic prescribing and broad-spectrum prescription for respiratory tract infections is high, and reveals potentials to change general practitioners' prescription behaviour, in order to maintain the positive situation in Norway as to antibiotic resistance.

Pharmacologically inappropriate prescriptions for elderly patients in general practice: How common? Baseline data from The Prescription Peer Academic Detailing (Rx-PAD) study

OBJECTIVE

To assess Norwegian general practitioners' (GPs') level of potentially harmful drug prescribing for elderly patients.

DESIGN

Prescription data for 12 months were retrospectively retrieved from the Norwegian Prescription Database (NorPD). Data were assessed in relation to 13 prescription quality indicators.

SETTING

General practice.

SUBJECTS

A total of 454 GPs attending continuous medical education (CME) groups in Southern Norway, 85,836 patients >or=70 years who received any prescription from the GPs during the study period.

MAIN OUTCOME MEASURES

Number of prescriptions assessed in relation to pharmacological inappropriateness based on a list of 13 explicit prescription quality indicators.

RESULTS

Some 18.4% of the patients (66% females with mean age 79.8 years, 34% males with mean age 78.7 years) received one or more inappropriate prescriptions from their GP. An NSAID in a potentially harmful combination with another drug (7%) and a long-acting benzodiazepine (4.6%) were the most frequent inappropriate prescriptions made. Doctor characteristics associated with more inappropriate prescribing practice were old age and working single-handed with many elderly patients.

CONCLUSION

The study reveals areas where GPs' prescribing practice for elderly patients can be improved and which can be targeted in educational interventions.

Can antibiotic prescriptions in respiratory tract infections be improved? A cluster-randomized educational intervention in general practice--the Prescription Peer Academic Detailing (Rx-PAD) Study [NCT00272155]

Background

More than half of all antibiotic prescriptions in general practice are issued for respiratory tract infections (RTIs), despite convincing evidence that many of these infections are caused by viruses. Frequent misuse of antimicrobial agents is of great global health concern, as we face an emerging worldwide threat of bacterial antibiotic resistance. There is an increasing need to identify determinants and patterns of antibiotic prescribing, in order to identify where clinical practice can be improved.

Methods/Design

Approximately 80 peer continuing medical education (CME) groups in southern Norway will be recruited to a cluster randomized trial. Participating groups will be randomized either to an intervention- or a control group. A multifaceted intervention has been tailored, where key components are educational outreach visits to the CME-groups, work-shops, audit and feedback. Prescription Peer Academic Detailers (Rx-PADs), who are trained GPs, will conduct the educational outreach visits. During these visits, evidence-based recommendations of antibiotic prescriptions for RTIs will be presented and software will be handed out for installation in participants PCs, enabling collection of prescription data. These data will subsequently be linked to corresponding data from the Norwegian Prescription Database (NorPD). Individual feedback reports will be sent all participating GPs during and one year after the intervention. Main outcomes are baseline proportion of inappropriate antibiotic prescriptions for RTIs and change in prescription patterns compared to baseline one year after the initiation of the tailored pedagogic intervention.

Discussion

Improvement of prescription patterns in medical practice is a challenging task. A thorough evaluation of guidelines for antibiotic treatment in RTIs may impose important benefits, whereas inappropriate prescribing entails substantial costs, as well as undesirable consequences like development of antibiotic resistance. Our hypothesis is that an educational intervention program will be effective in improving prescription patterns by reducing the total number of antibiotic prescriptions, as well as reducing the amount of broad-spectrum antibiotics, with special emphasis on macrolides.

A cluster-randomized educational intervention to reduce inappropriate prescription patterns for elderly patients in general practice--The Prescription Peer Academic Detailing (Rx-PAD) study [NCT00281450]

Background

Age-related alterations in metabolism and excretion of medications increase the risk of adverse drug events in the elderly. Inappropriate polypharmacy and prescription practice entails increased burdens of impaired quality of life and drug related morbidity and mortality. The main objective of this trial is to evaluate effects of a tailored educational intervention towards general practitioners (GPs) aimed at supporting the implementation of a safer drug prescribing practice for elderly patients ≥ 70 years.

Methods/design

Approximately 80 peer continuing medical education (CME) groups (about 600 GPs) in southern Norway will be recruited to a cluster randomized trial. Participating groups will be randomized either to an intervention- or a control group. The control group will not receive any intervention towards prescription patterns in elderly, but will be the target of an educational intervention for prescription of antibiotics for respiratory tract infections. A multifaceted intervention has been tailored, where key components are educational outreach visits to the CME-groups, work-shops, audit and feedback. Prescription Peer Academic Detailers (Rx-PADs), who are trained GPs, will conduct the educational outreach visits. During these visits, a set of quality indicators (QIs), i.e. explicit recommendations for safer prescribing for elderly patients, will be presented and discussed. Software will be handed out for installation in participants' practice computers to enable extraction of pre-defined prescription data. These data will subsequently be linked to corresponding data from the Norwegian Prescription Database (NorPD). Individual feedback reports will be sent all participating GPs during and one year after the intervention. Feedback reports will include QI-scores on individual- and group levels, before and after the intervention. The main outcome of this trial is the change in proportions of inappropriate prescriptions (QIs) for elderly patients ≥ 70 years following intervention, compared to baseline levels.

Discussion

Improvement of prescription patterns in medical practice is a challenging task. Evidence suggests that a thorough evaluation of diagnostic indications for drug treatment in the elderly and/or a reduction of potentially inappropriate drugs may impose significant clinical benefits. Our hypothesis is that an educational intervention program will be effective in improving prescribing patterns for elderly patients in GP settings.
