Early-career general practitioners' antibiotic prescribing for acute infections: a systematic review

BACKGROUND

Antimicrobial resistance is a worldwide threat, exacerbated by inappropriate prescribing. Most antibiotic prescribing occurs in primary care. Early-career GPs are important for the future of antibiotic prescribing and curbing antimicrobial resistance.

OBJECTIVES

To determine antibiotic prescribing patterns by early-career GPs for common acute infections.

METHODS

A systematic literature search was conducted using PubMed, Embase and Scopus. Two authors independently screened abstracts and full texts for inclusion. Primary outcomes were antibiotic prescribing rates for common acute infections by GPs with experience of 10 years or less. Secondary outcomes were any associations between working experience and antibiotic prescribing.

RESULTS

Of 1483 records retrieved, we identified 41 relevant studies. Early-career GPs were less likely to prescribe antibiotics compared with their more experienced colleagues (OR range 0.23-0.67). Their antibiotic prescribing rates for 'any respiratory condition' ranged from 14.6% to 52%, and for upper respiratory tract infections from 13.5% to 33%. Prescribing for acute bronchitis varied by country, from 15.9% in Sweden to 26% in the USA and 63%-73% in Australia. Condition-specific data for all other included acute infections, such as sinusitis and acute otitis media, were limited to the Australian context.

CONCLUSIONS

Early-career GPs prescribe fewer antibiotics than later-career GPs. However, there are still significant improvements to be made for common acute conditions, as their prescribing is higher than recommended benchmarks. Addressing antimicrobial resistance requires an ongoing worldwide effort and early-career GPs should be the target for long-term change.

Trends in systemic antifungal use in Australia, 2005-2016: a time-series analysis

Data on antifungal utilization trends are important to encourage antifungal stewardship. This study explored the utilization of antifungal agents for systemic use and the impact of reimbursement policy changes in Australia. We analyzed national data from the Australian Pharmaceutical Benefits Scheme (PBS) (2005-2016). We examined patterns of use over time and the impact of reimbursement decisions on antifungal use with an interrupted time-series model. In 2005-2016, there has been an increase in the use of most antifungals, especially fluconazole, itraconazole and posaconazole. Ketoconazole was the most commonly dispensed systemic antifungal (46.0%) before its PBS listing removal, when it was replaced by fluconazole (69.8%). The PBS event "Fluconazole and itraconazole restrictions eased" led to increased use of fluconazole (0.025/1000 per day with no delay). Both the largest rates and numerical increase were among obstetricians and gynecologists (1,969%; 1,851 dispensed prescriptions) and dermatologists (1,723%; 1,689 dispensed prescriptions) except general practitioner (2010-2016). This is the first Australian national longitudinal estimate of systemic antifungal use. It shows an overall increase in prescribing of most antifungals during study period, with reimbursement decisions impacting utilization. These data provide a baseline to inform development of national antifungal guidelines and policies to encourage more targeted antifungal stewardship.

ICU Patients' Antibiotic Exposure and Triazole-Resistance in Invasive Candidiasis: Parallel Analysis of Aggregated and Individual Data

Background: The relationship between antibiotic use and the incidence of triazole-resistant phenotypes of invasive candidiasis (IC) in critically ill patients is unclear. Different methodologies on determining this relationship may yield different results.

Methods: A retrospective multicenter observational analysis was conducted to investigate exposure to antibiotics and the incidence of non-duplicate clinical isolates of Candida spp. resistant to fluconazole, voriconazole, or both during November 2013 to April 2018, using two different methodologies: group-level (time-series analysis) and individual-patient-level (regression analysis and propensity-score adjusting).

Results: Of 393 identified Candida spp. from 388 critically ill patients, there were three phenotypes of IC identified: fluconazole-resistance (FR, 63, 16.0%); voriconazole-resistance (VR, 46, 11.7%); and cross-resistance between fluconazole and voriconazole (CR, 32, 8.1%). Exposure to several antibacterial agents with activity against the anaerobic gastrointestinal flora, especially third-generation cefalosporins (mainly cefoperazone/sulbactam and ceftriaxone), but not triazoles, have an immediate effect (time lag = 0) on subsequent ICU-acquired triazole-resistant IC in the group-level (p < 0.05). When the same patient database was analyzed at the individual-patient-level, we found that exposure to many antifungal agents was significantly associated with triazole-resistance (fluconazole [adjusted odds ratio (aOR) = 2.73] or caspofungin [aOR = 11.32] on FR, voriconazole [aOR = 2.87] on CR). Compared to the mono-triazole-resistant phenotype, CR IC has worse clinical outcomes (14-days mortality) and a higher level of resistance.

Conclusion: Group-level and individual-patient-level analyses of antibiotic-use-versus-resistance relations yielded distinct but valuable results. Antibacterials with antianaerobic activity and antifungals might have “indirect” and “direct” effect on triazole-resistant IC, respectively.

Antifungal agents for invasive candidiasis in non-neutropenic critically ill adults: What do the guidelines recommend?

OBJECTIVES

Recommendations in clinical practice guidelines (CPG) may differ and cause confusion. Our objective was to appraise CPGs for antifungal treatment of invasive candidiasis (IC) in non-neutropenic critically ill adult patients.

METHODS

We systematically searched the literature for CPGs published between 2008 and 2018. We assessed the quality of each guideline using six domains of the AGREE II instrument. We extracted and compared recommendations for different treatment strategies and assessed content quality.

RESULTS

Of 19 guidelines, the mean overall AGREE II score was 58%. The domain 'clarity of presentation' received the highest scores (88%) and 'applicability' the lowest (18%). CPGs provided detailed recommendations on antifungal prophylaxis (n = 10), with fluconazole recommended as initial prophylaxis in all seven CPGs citing a specific drug. Echinocandin was recommended as the initial drug in all 16 CPGs supporting empirical/pre-emptive treatment; and in 18 of 19 for targeted invasive candidiasis treatment. However, it remains unclear when to initiate prophylaxis, empirical or pre-emptive therapy or when to step down.

CONCLUSIONS

The methodological quality of CPGs for antifungal treatment of IC in non-neutropenic critically ill patients is suboptimal. Some treatment recommendations were inconsistent across indications and require local guidance to help clinicians make better informed decisions.

Network meta-analysis and pharmacoeconomic evaluation of antibiotics for the treatment of patients infected with complicated skin and soft structure infection and hospital-acquired or ventilator-associated penumonia

Background

Infections due to methicillin-resistant Staphylococcus aureus (MRSA) cause serious health risks and significant economic burdens and the preferred drugs are still controversial.

Methods

We performed a network meta-analysis (NMA) to compare the efficacy and safety of antibiotics used to treat inpatients with complicated skin and soft structure infections (cSSSI) or hospital-acquired or ventilator-associated pneumonia (HAP/VAP). We also developed a decision tree model to assess the cost-effectiveness of antibiotics.

Results

Forty-nine randomized controlled trials met the inclusion criteria (34 for cSSSI, 15 for HAP/VAP) and compared the efficacy and safety of 16 antibiotics. For cSSSI, NMA indicated that for clinical cure, linezolid was superior than vancomycin (odds ratio (OR) 1.55, 95% confidence interval (CI) 1.19–2.02), while tedizolid (OR 1.39, CI 0.70–2.76) was similar to vancomycin. In terms of safety, there were no significant differences between any two interventions on total adverse events. Based on drug and hospital costs in America, the incremental cost-effectiveness ratios (ICERs) per life-year saved for linezolid and tedizolid compared with vancomycin were US$2833 and US$5523. For HAP/VAP, there were no significant effects either for clinical cure or for safety endpoints between linezolid and vancomycin in NMA. ICERs per life-year saved for linezolid compared with vancomycin were US$2185.

Conclusion

In these clinical trials, considering efficacy, safety, and cost-effectivenes, linezolid and tedizolid showed their superiority in MRSA cSSSI; while linezolid might be recommended to treat MRSA pneumonia. Although vancomycin was not cost-effective in pharmacoeconomic evaluation, it is still the first-line treatment for MRSA infection in the clinical practice. This study might provide new insights of therapeutic choices for patients with MRSA infections whilst awaiting the arrival of higher quality evidence.

Learnings and challenges to deploy an interprofessional and independent medical education programme to a new audience

The importance of interprofessional education (IPE) in continuing medical education and professional development has long been recognised by health organisations and academic societies, benefiting not only patient outcomes and interprofessional relationships but also overall health systems and workforce shortage. We report on the outcomes of an Australian IPE activity on medication-overuse headache (MOH) with general practitioners (GPs) and community pharmacists as learners. The design of the activity, which followed the predisposing–enabling–reinforcing instructional framework by Green and Kreuter, aimed to: (1) improve knowledge and foster a willingness in GPs and pharmacists to work collaboratively to enhance the prevention, diagnosis and management of MOH; and (2) address their educational gap by demonstrating the utility of a blended learning IPE strategy on MOH. Integrated into the activity was an assessment of its effectiveness and impact to instil change in the participants’ knowledge of MOH, attitude and willingness to treat, and clinical practice behaviours of GPs and pharmacists to work together. The learners gained knowledge and confidence in diagnosing and managing MOH and in their ability to educate patients. The IPE approach suited the activity and was valued by the participating GPs and pharmacists, who seldom experience such learning formats. However, for educational providers in Australia, developing and deploying an independent medical education (IME) programme can be challenging. Providers of IMEs need to be aware of the potential pitfalls when competing with pharmaceutical-company-sponsored and delivered programmes.

Postpartum consultations in Australian general practice

Many GPs undertake postpartum care for women and their infants. GP follow-up enables early identification and management of problems, education and support for parenting, and reconnection with general practice following the birth. However, there is little information about GPs' understanding of their role in postpartum care and how it is undertaken. This cross-sectional survey of GPs in Southern Queensland, conducted between February and July 2013, describes the involvement of GPs in postpartum care. GPs were posted a 52-item questionnaire adapted from a previous Victorian GP study and were telephoned 2 weeks later. GPs completed the survey on paper or online. The response rate was 17.4% (163 GPs). Approximately 39% were uncertain whether women were happy with the GP-provided postpartum care. GPs' recommendations for the timing of postpartum reviews were inconsistent within and across birthing sectors and consultations took longer than anticipated. Developing guidelines around the timing and appropriate length of postpartum consultations could assist GPs in providing appropriate care for mothers and infants.

Continuity of care in the post partum period: general practitioner experiences with communication

Objectives Informational and management continuity of care assists in providing a seamless transition for women and infants from tertiary or secondary to primary care during the post partum period. Few studies have evaluated the interaction between different aspects of the health system following a woman’s discharge from hospital after the birth of her infant. The present study describes how general practitioners (GPs) experience communications with hospitals and other post partum care providers relevant to continuity of care. Methods In the present cross-sectional study, a 52-item questionnaire adapted from a previously used survey was mailed to 932 GPs in southern Queensland, Australia, between February and July 2013. Questionnaire items included participant demographics, the timeliness and usability of discharge summaries, communication with other post partum care providers and consultation practices. Results The response rate was 17.4%. Nearly one-quarter of participants never or rarely received a hospital discharge summary in a timely manner and most considered the summaries somewhat useful. Few GPs (14.3%) had contact with or received information from domiciliary midwives who conducted post partum home visits. A higher proportion (38%) had some communication with a Child and Family Health nurse in the month before the survey. Conclusions Information flow from hospital to general practice and between other post partum care providers is less than ideal and may affect ongoing care for mothers and infants, especially those at risk. Knowledge exchange between healthcare services and initiatives to improve information sharing needs to be developed and implemented. What is already known on this topic? Transitions from tertiary or secondary care to primary care and between primary care providers are often times of vulnerability for patients, including women and infants in the post partum period. There is little information documenting communications between different maternity services and GPs that facilitate ongoing care. What does this paper add? There are significant gaps in the exchange of information about post partum women and infants from hospitals to GPs and a lack of communication between GPs and other post partum care providers, such as domiciliary midwives and Child and Family Health nurses. What are the implications for practitioners? Improvements in the timeliness, presentation and content of hospital discharge summaries, as well as enhancing channels of communication, collaboration, cooperation and information sharing between providers of community post partum care, are necessary if mothers are to receive the best care possible.

Supporting primary healthcare professionals to care for people with intellectual disability: a research agenda

BACKGROUND

The vast health inequities experienced by people with intellectual disability remain indisputable. Persistent and contemporary challenges exist for primary healthcare providers and researchers working to contribute to improvements to the health and well-being of people with intellectual disability. Over two decades after the only review of supports for primary healthcare providers was published, this paper contributes to an evolving research agenda that aims to make meaningful gains in health-related outcomes for this group.

METHODS

The present authors updated the existing review by searching the international literature for developments and evaluations of multinational models of care.

RESULTS

Based on our review, we present three strategies to support primary healthcare providers: (i) effectively using what we know, (ii) considering other strategies that offer support to primary healthcare professionals and (iii) researching primary health care at the system level.

CONCLUSIONS

Strengthening primary care by supporting equitable provision of health-related care for people with intellectual disability is a much needed step towards improving health outcomes among people with intellectual disability. More descriptive quantitative and qualitative research, as well as intervention-based research underpinned by rigorous mixed-methods evaluating these strategies at the primary care level, which is sensitive to the needs of people with intellectual disability will assist primary care providers to provide better care and achieve better health outcomes.

ACCESSIBLE ABSTRACT

Many people with intellectual disability have poor health. The authors reviewed what has been written by other researchers about how to improve the health of people with intellectual disability. In the future, people who support adults with intellectual disability should continue doing what they do well, think of other ways to improve health, and do more research about health. At all times, the needs of people with intellectual disability should be the greatest concern for those trying to support them.

Treating chronic fatigue syndrome - a study into the scientific evidence for pharmacological treatments

BACKGROUND

Chronic fatigue syndrome, or myalgic encephalomyelitis (CFS), is a severe disabling condition. Patients with CFS usually trial many different medicines, both conventional and complementary. An overview of the pharmacological treatments used by CFS patients and the available evidence underpinning the use of these treatments would be of great value to both patients and their healthcare providers.

METHODS

Ninety-four CFS patients recruited into an Australian study investigating immunological biomarkers filled out a questionnaire assessing the medicines they were taking. Evidence from randomised clinical trials was sought in biomedical databases.

RESULTS

The 94 CFS patients used 474 different medicines and supplements. The most commonly used medicines were antidepressants, analgesics, sedatives, and B vitamins. We identified 20 randomised controlled trials studying these medicines in CFS patients.

DISCUSSION

While conventional and complementary medicines are widely used by CFS patients, the evidence for effectiveness in CFS is very limited.

Women with intellectual disabilities--a study of sexuality, sexual abuse and protection skills

BACKGROUND

Sexual abuse and abusive relationships are known to be especially common in people with intellectual disability. This study explored how women with intellectual disability understand sex, relationships and sexual abuse, the effects of sexual abuse on their lives, and how successfully they protect themselves from abuse.

METHODS

Semistructured narrative interviews with nine women with mild intellectual disability in Queensland, Australia. Interviews were audio recorded, transcribed, coded and analysed qualitatively.

RESULTS

Major themes that emerged were: sexual knowledge and sources of knowledge; negotiating sexual relationships; declining unwanted sexual contact; self protection strategies; sexual abuse experiences; and sequelae of sexual abuse.

DISCUSSION

Most participants reported unwanted or abusive sexual experiences. They described sequelae such as difficulties with sex and relationships, and anxiety and depression. They described themselves as having inadequate self protection skills and difficulty reporting abuse and obtaining appropriate support. Their understanding of sex was limited and they lacked the literacy and other skills to seek information independently. It is important for general practitioners to be aware of the possibility of sexual abuse against women with intellectual disability, and to offer appropriate interventions.

Improving health outcomes in young people - a holistic, team based approach

BACKGROUND

Young people aged 12-25 years are poorly serviced by current models of healthcare; they are under represented in Medicare data and are poor seekers of healthcare. However, the majority of mental health problems commence during this age span, significant sexual health issues arise, and there is poor compliance with treatment for chronic disease.

OBJECTIVE

This article describes a holistic, multisector primary healthcare delivery model which may provide a way forward to improve both access and outcomes for young people.

DISCUSSION

The 'headspace Gold Coast' model incorporates the relationship the young person has with both the organisation and the individuals within it; a focus on social and vocational rehabilitation; and a team based approach. The model provided at headspace serves an unmet need for young people in urban settings. However, more and ongoing support is crucial, including options for integration into existing primary care.

Does amoxicillin improve outcomes in patients with purulent rhinorrhea? A pragmatic randomized double-blind controlled trial in family practice

OBJECTIVE

To compare the efficacy of amoxicillin vs placebo in patients with an acute upper respiratory tract infection and purulent rhinorrhea.

STUDY DESIGN

Double-blind randomized placebo-controlled trial.

POPULATION

The 416 patients included from 69 family practices were 12 years or older, presenting with acute upper respiratory complaints, and having a history of purulent rhinorrhea and no signs of complications of sinusitis.

OUTCOMES MEASURED

Therapy success (disappearance of symptoms that most greatly affected the patient's health) at day 10 and duration of general illness, pain, and purulent rhinorrhea.

RESULTS

Therapy was successful in 35% of patients with amoxicillin and in 29% of patients with placebo (relative risk [RR] 1.14, 95% confidence interval [CI], 0.92-1.42). There was no effect on duration of general illness or pain. Duration of purulent rhinorrhea was shortened by amoxicillin (9 days vs 14 for clearing of purulent rhinorrhea in 75% of patients; P =.007). Diarrhea was more frequent with amoxicillin (29% vs 19%, RR 1.28, 95% CI, 1.05-1.57). No complications were reported. One patient (0.5%) receiving amoxicillin and 7 (3.4%) receiving placebo discontinued trial therapy because of exacerbation of symptoms (RR 0.25, 95% CI 0.04-1.56, P =.07). All 8 patients recovered with antibiotic therapy.

CONCLUSIONS

Amoxicillin has a beneficial effect on purulent rhinorrhea caused by an acute infection of the nose or sinuses but not on general recovery. The practical implication is that all such patients, whatever the suspected diagnosis, can be safely treated with symptomatic therapy and instructed to return if symptoms worsen.
