Effectiveness of empathy in general practice: a systematic review

Background

Empathy as a characteristic of patient–physician communication in both general practice and clinical care is considered to be the backbone of the patient–physician relationship. Although the value of empathy is seldom debated, its effectiveness is little discussed in general practice. This literature review explores the effectiveness of empathy in general practice. Effects that are discussed are: patient satisfaction and adherence, feelings of anxiety and stress, patient enablement, diagnostics related to information exchange, and clinical outcomes.

Aim

To review the existing literature concerning all studies published in the last 15 years on the effectiveness of physician empathy in general practice.

Design and setting

Systematic literature search.

Method

Searches of PubMed, EMBASE, and PsychINFO databases were undertaken, with citation searches of key studies and papers. Original studies published in English between July 1995 and July 2011, containing empirical data about patient experience of GPs’ empathy, were included. Qualitative assessment was applied using Giacomini and Cook’s criteria.

Results

After screening the literature using specified selection criteria, 964 original studies were selected; of these, seven were included in this review after applying quality assessment. There is a good correlation between physician empathy and patient satisfaction and a direct positive relationship with strengthening patient enablement. Empathy lowers patients’ anxiety and distress and delivers significantly better clinical outcomes.

Conclusion

Although only a small number of studies could be used in this search, the general outcome seems to be that empathy in the patient–physician communication in general practice is of unquestionable importance.     

Effectiveness of general practice-based health checks: a systematic review and meta-analysis

Background

A recent review concluded that general health checks fail to reduce mortality in adults.

Aim

This review focuses on general practice-based health checks and their effects on both surrogate and final outcomes.

Design and setting

Systematic search of PubMed, Embase, and the Cochrane Central Register of Controlled Trials.

Method

Relevant data were extracted from randomised trials comparing the health outcomes of general practice-based health checks versus usual care in middle-aged populations.

Results

Six trials were included. The end-point differences between the intervention and control arms in total cholesterol (TC), systolic and diastolic blood pressure (SBP, DBP), and body mass index (BMI) were −0.13 mmol/l (95% confidence interval [CI] = −0.19 to −0.07), −3.65 mmHg (95% CI = −6.50 to −0.81), −1.79 mmHg (95% CI = −2.93 to −0.64), and −0.45 kg/m² (95% CI = −0.66 to −0.24), respectively. The odds of a patient remaining at ‘high risk’ with elevated TC, SBP, DBP, BMI or continuing smoking were 0.63 (95% CI = 0.50 to 0.79), 0.59 (95% CI = 0.28 to 1.23), 0.63 (95% CI = 0.53 to 0.74), 0.89 (95% CI = 0.81 to 0.98), and 0.91 (95% CI = 0.82 to 1.02), respectively. There was little evidence of a difference in total mortality (OR 1.03, 95% CI = 0.90 to 1.18). Higher CVD mortality was observed in the intervention group (OR 1.30, 95% CI = 1.02 to 1.66).

Conclusion

General practice-based health checks are associated with statistically significant, albeit clinically small, improvements in surrogate outcome control, especially among high-risk patients. Most studies were not originally designed to assess mortality.     

The prognostic value of tumour-associated macrophages in Non-Hodgkin's lymphoma: A systematic review and meta-analysis

Tumour-associated macrophages (TAMs) play an important role in the tumour environment and were reported to be associated with poor prognosis in several tumours. However, the prognostic significance of TAMs in Non-Hodgkin's Lymphoma (NHL) remains controversial. Consequently, we aimed to evaluate the relationship between subpopulations of TAMs and clinical outcomes in NHL patients. We did a comprehensive search of the PubMed, elsevier ScienceDirect, and Cochrane databases and extracted hazard ratio (HR) and their corresponding 95% confidence intervals (95% CIs) from eligible studies. Pooling total effect value by the stata statistical software and analysing correlation of TAMs with overall survival (OS) and progression-free survival (PFS). Furthermore, subgroup analysis and sensitivity analysis were also conducted. We deemed eleven studies, including 1211 NHL patients. Our study demonstrated that high-density CD68⁺ TAMs are associated with poor OS (HR: 1.17; 95% CI, 0.81-1.54; P = .000) and poor PFS (HR: 1.15; 95% CI, 0.63-1.67; P = .000) compared with low-density CD68⁺ TAMs in the tumour microenvironment. Similarly, high-density CD163⁺ TAMs can also predict poor OS (HR: 1.52; 95% CI, 1.11-1.92; P = .000) and shorter PFS (HR: 1.52; 95% CI, 0.73-2.30; P = .000). In addition, the high CD163⁺/CD68⁺ TAMs ratio is significantly correlated with poor OS (HR: 3.59; 95% CI, 0.77-6.40; P = .013). However, in our subgroup analysis, high-density CD68⁺ TAMs in the tumour microenvironment is associated with better OS (HR: 0.75; 95% CI, 0.41-1.09; P = .000) in NHL patients treated with rituximab chemotherapy. Our results suggest that TAMs are a robust predictor of outcomes in NHL.     

Primary care organisational interventions for secondary prevention of ischaemic heart disease: a systematic review and meta-analysis

BackgroundIschaemic heart disease (IHD) is the most common cause of death worldwide.AimTo determine the long-term impact of organisational interventions for secondary prevention of IHD.MethodSearches were conducted for randomised controlled trials of patients with established IHD, with long-term follow-up, of cardiac secondary prevention programmes targeting organisational change in primary care or community settings. A random-effects model was used and risk ratios were calculated.ResultsFive studies were included with 4005 participants. Meta-analysis of four studies with mortality data at 4.7–6 years showed that organisational interventions were associated with approximately 20% reduced mortality, with a risk ratio (RR) for all-cause mortality of 0.79 (95% confidence interval [CI] = 0.66 to 0.93), and a RR for cardiac-related mortality of 0.74 (95% CI = 0.58 to 0.94). Two studies reported mortality data at 10 years. Analysis of these data showed no significant differences between groups. There were insufficient data to conduct a meta-analysis on the effect of interventions on hospital admissions. Additional analyses showed no significant association between organisational interventions and risk factor management or appropriate prescribing at 4.7–6 years.ConclusionCardiac secondary prevention programmes targeting organisational change are associated with a reduced risk of death for at least 4–6 years. There is insufficient evidence to conclude whether this beneficial effect is maintained indefinitely.     

Refugee experiences of general practice in countries of resettlement: a literature review

Background

Refugees and asylum seekers often struggle to use general practice services in resettlement countries.

Aim

To describe and analyse the literature on the experiences of refugees and asylum seekers using general practice services in countries of resettlement.

Design and setting

Literature review using systematic search and narrative data extraction and synthesis methodologies. International, peer-reviewed literature published in English language between 1990 and 2013.

Method

Embase, Ovid MEDLINE, PsycINFO, CSA Sociological Abstracts, and CINAHL databases were searched using the terms: refugee, asylum seeker, experience, perception, doctor, physician, and general practitioner. Titles, abstracts and full texts were reviewed and were critically appraised. Narrative themes describing the refugee or asylum seeker’s personal experiences of general practice services were identified, coded, and analysed.

Results

From 8722 papers, 85 were fully reviewed and 23 included. These represented the experiences of approximately 864 individuals using general practice services across 11 countries. Common narrative themes that emerged were: difficulties accessing general practice services, language barriers, poor doctor–patient relationships, and problems with the cultural acceptability of medical care.

Conclusion

The difficulties refugees and asylum seekers experience accessing and using general practice services could be addressed by providing practical support for patients to register, make appointments, and attend services, and through using interpreters. Clinicians should look beyond refugee stereotypes to focus on the needs and expectations of the individual. They should provide clear explanations about unfamiliar clinical processes and treatments while offering timely management.     

Early identification of palliative care patients in general practice: development of RADboud indicators for PAlliative Care Needs (RADPAC)

Background

According to the World Health Organization (WHO) definition, palliative care should be initiated in an early phase and not be restricted to terminal care. In the literature, no validated tools predicting the optimal timing for initiating palliative care have been determined.

Aim

The aim of this study was to systematically develop a tool for GPs with which they can identify patients with congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), and cancer respectively, who could benefit from proactive palliative care.

Design

A three-step procedure, including a literature review, focus group interviews with input from the multidisciplinary field of palliative healthcare professionals, and a modified Rand Delphi process with GPs.

Method

The three-step procedure was used to develop sets of indicators for the early identification of CHF, COPD, and cancer patients who could benefit from palliative care.

Results

Three comprehensive sets of indicators were developed to support GPs in identifying patients with CHF, COPD, and cancer in need of palliative care. For CHF, seven indicators were found: for example, frequent hospital admissions. For COPD, six indicators were found: such as, Karnofsky score ≤50%. For cancer, eight indicators were found: for example, worse prognosis of the primary tumour.

Conclusion

The RADboud indicators for PAlliative Care Needs (RADPAC) is the first tool developed from a combination of scientific evidence and practice experience that can help GPs in the identification of patients with CHF, COPD, or cancer, in need of palliative care. Applying the RADPAC facilitates the start of proactive palliative care and aims to improve the quality of palliative care in general practice.     

Quality of care provided to people with dementia: utilisation and quality of the annual dementia review in general practice

Background

Primary care services are often the main healthcare service for people with dementia; as such, good-quality care at this level is important.

Aim

To measure the quality of care provided to people with dementia in general practice using routinely collected data, and to explore associated patient and practice factors.

Design and setting

Observational, cross-sectional review of medical records from general practices (n = 52) in five primary care trusts.

Method

A total of 994 people with dementia were identified from dementia registers. An unweighted quality-of-care score was constructed using information collected in the annual dementia review, together with pharmacological management of cognitive and non-cognitive symptoms. Multilevel modelling was carried out to identify factors associated with quality-of-care scores.

Results

In total, 599 out of 745 (80%) patients with dementia had received an annual dementia review; however, a social care review or discussion with carers was evident in just 305 (51%) and 367 (61%) of those 599 cases, respectively. Despite high prevalence of vascular disease, over a quarter (n = 259, 26%) of all patients with dementia were prescribed antipsychotics; only 57% (n = 148) of these had undergone medication review in the previous 6 months. Those with vascular dementia who were registered with single-handed practices received poorer quality of care than those registered with practices that had more than one GP.

Conclusion

Although the number of people with dementia with a record of an annual dementia review is high, the quality of these reviews is suboptimal. The quality score developed in this study could be used as one source of data to identify weaknesses in practice activity that need to be corrected, and so would be of value to commissioners and regulators, as well as practices themselves.     

Digital communication between clinician and patient and the impact on marginalised groups: a realist review in general practice

Background

Increasingly, the NHS is embracing the use of digital communication technology for communication between clinicians and patients. Policymakers deem digital clinical communication as presenting a solution to the capacity issues currently faced by general practice. There is some concern that these technologies may exacerbate existing inequalities in accessing health care. It is not known what impact they may have on groups who are already marginalised in their ability to access general practice.

Aim

To assess the potential impact of the availability of digital clinician–patient communication on marginalised groups’ access to general practice in the UK.

Design and setting

Realist review in general practice.

Method

A four-step realist review process was used: to define the scope of the review; to search for and scrutinise evidence; to extract and synthesise evidence; and to develop a narrative, including hypotheses.

Results

Digital communication has the potential to overcome the following barriers for marginalised groups: practical access issues, previous negative experiences with healthcare service/staff, and stigmatising reactions from staff and other patients. It may reduce patient-related barriers by offering anonymity and offers advantages to patients who require an interpreter. It does not impact on inability to communicate with healthcare professionals or on a lack of candidacy. It is likely to work best in the context of a pre-existing clinician–patient relationship.

Conclusion

Digital communication technology offers increased opportunities for marginalised groups to access health care. However, it cannot remove all barriers to care for these groups. It is likely that they will remain disadvantaged relative to other population groups after their introduction.     

Global seroprevalence and prevalence of infection of influenza in dogs (Canis familiaris): A systematic review and meta-analysis

Influenza in dogs holds considerable public health significance due to their close companionship with humans, yet several facets of this phenomenon remain largely unexplored. This study undertook a systematic review and meta-analysis of observational studies to gauge the global seroprevalence of influenza in dogs. We also assessed whether pet dogs exhibited a higher seroprevalence of influenza compared to non-pet dogs, explored seasonal variations in seroprevalence, scrutinised the design and reporting standards of existing studies, and elucidated the geographical distribution of canine influenza virus (cIV). A comprehensive analysis of 97 studies spanning 27 countries revealed that seroprevalence of various influenza strains in dogs consistently registered below 10% and exhibited relative stability over the past decade. Significantly, we noted that seroprevalence of human influenza virus was notably higher in pet dogs compared to their non-pet counterparts, whereas seroprevalence of other influenza strains remained relatively uniform among both categories of dogs. Seasonal variations in seroprevalence of cIV were not observed. In summary, our findings indicated the global circulation of cIV strains H3N2 and H3N8, with other strains primarily confined to China. Given the lack of reported cases of the transmission of cIV from dogs to humans, our findings suggest a higher risk of reverse zoonosis than zoonosis. Finally, we strongly advocate for standardised reporting guidelines to underpin future canine influenza research endeavours.     

MicroRNAs as potential biomarkers for the diagnosis of Traumatic Brain Injury: A systematic review and meta-analysis

Background: Traumatic brain injury (TBI) is a sudden trauma on the head, in which severe TBI (sTBI) is usually associated with death and long-term disability. MicroRNAs (miRNAs) are potential biomarkers of diverse diseases, including TBI. However, few systematic reviews and meta-analyses have been conducted to determine the clinical value of miRNAs expression in TBI patients.Methods: We conducted this systematic review and meta-analysis study according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched PubMed, Embase, the Cochrane Library, Web of Science, from inception to August 26, 2020. We included articles written in English that have reported on the diagnostic value of miRNAs expression in TBI patients. We excluded studies that did not provided sufficient information to construct the 2×2 contingency table.Results: Eight studies investigating the diagnostic value of miRNA in TBI were analyzed in this study. The overall sensitivity, specificity and area under the curve (AUC) of miRNAs in diagnosis of TBI were 89% [95% confidence interval (CI): 0.84-0.93], 92% (95% CI 0.82-0.97) and 95% (95% CI 0.93-0.97). We found that panels of multiple miRNAs could improve the diagnostic accuracy of TBI. Samples from blood and brain tissue have significantly enhanced diagnostic accuracy, when compared with saliva. The AUC of miRNAs in severe TBI was 0.97, with 91% sensitivity and 92% specificity.Conclusion: This systematic review and meta-analysis demonstrated that miRNAs could be potential diagnostic markers in TBI patients. MiRNAs detected in blood and brain tissue display high accuracy for TBI diagnosis.     

Cancer suspicion in general practice: the role of symptoms and patient characteristics,and their association with subsequent cancer

Background

Awareness of detail in ambiguous complaints may help GPs suspect cancer when a malignancy is present.

Aim

To study the contribution of symptoms and patient characteristics to GPs’ suspicions of cancer being present, and to what degree these suspicions were confirmed.

Design and setting

Prospective cohort study of patients in 283 rural and urban general practices throughout Norway.

Method

During patient consultations (over a period of 10 days) GPs registered whether there was a suspicion of cancer when a patient presented with at least one of seven focal symptoms and three general symptoms commonly considered to be warning signs of cancer. Follow-up questionnaires were sent to GPs 6–7 months later, requesting information on any subsequent diagnosis of cancer in these patients.

Results

Out of 51 073 patients, 6321 presented with warning signs of cancer; of these, 106 had a subsequent cancer diagnosis. Of the patients presenting with warning signs, 1515 (24%) patients were suspected of having cancer; this was correct for 3.8% of suspected cases. Of the 106 patients diagnosed with cancer who presented with warning signs, cancer was suspected in 58 (54.7%). GPs’ correct cancer suspicions were six times more frequent than their erroneous lack of suspicion. Multiple symptoms, previous cancer, comorbidity, and multiple consultations increased the probability of cancer, but only multiple symptoms and previous cancer increased suspicion. Suspicion led to an increase in the number of diagnostic procedures undertaken. The proportion of cancer cases where GPs recorded a lack of suspicion was relatively small, but important.

Conclusion

Selected symptoms appropriately resulted in GPs suspecting cancer. Comorbidity and multiple consultations were underestimated by GPs as factors associated with cancer. Cancer suspicion should rely on symptoms in combination with other relevant information.     

Measuring depression severity in general practice: discriminatory performance of the PHQ-9, HADS-D, and BDI-II

Background

The UK Quality and Outcomes Framework (QOF) rewards practices for measuring symptom severity in patients with depression, but the endorsed scales have not been comprehensively validated for this purpose.

Aim

To assess the discriminatory performance of the QOF depression severity measures.

Design and setting

Psychometric assessment in nine Scottish general practices.

Method

Adult primary care patients diagnosed with depression were invited to participate. The HADS-D, PHQ-9, and BDI-II were assessed against the HRSD-17 interview. Discriminatory performance was determined relative to the HRSD-17 cut-offs for symptoms of at least moderate severity, as per criteria set by the American Psychiatric Association (APA) and NICE. Receiver operating characteristic curves were plotted and area under the curve (AUC), sensitivity, specificity, and likelihood ratios (LRs) calculated.

Results

A total of 267 were recruited per protocol, mean age = 49.8 years (standard deviation [SD] = 14.1), 70% female, mean HRSD-17=12.6 (SD = 7.62, range = 0–34). For APA criteria, AUCs were: HADS-D = 0.84; PHQ-9 = 0.90; and BDI-II = 0.86. Optimal sensitivity and specificity were reached where HADS-D ≥9 (74%, 76%); PHQ-9 ≥12 (77%, 79%), and BDI-II ≥23 (74%, 75%). For NICE criteria: HADS-D AUC = 0.89; PHQ-9 AUC = 0.93; and BDI-II AUC = 0.90. Optimal sensitivity and specificity were reached where HADS-D ≥10 (82%, 75%), PHQ-9 ≥15 (89%, 83%), and BDI-II ≥28 (83%, 80%). LRs did not provide evidence of sufficient accuracy for clinical use.

Conclusion

As selecting treatment according to depression severity is informed by an evidence base derived from trials using HRSD-17, and none of the measures tested aligned adequately with that tool, they are inappropriate for use.     

Examining the efficacy of social-psychological interventions for the management of fatigue in end-stage kidney disease (ESKD): a systematic review with meta-analysis

Fatigue affects between 42% and 89% of end-stage kidney disease (ESKD) patients, with significant repercussions on quality of life and clinical outcomes. Fatigue management revolves around pharmacotherapy or exercise, which have only modest and short-term improvements. The aim of this systematic review was to investigate whether social-psychological interventions are effective at reducing fatigue in ESKD. Databases were searched to identify randomized controlled trials (RCTs) and quasi-RCTs that determined the effect of social-psychological interventions on fatigue (primary or secondary outcome), in the renal patient population. A meta-analysis was conducted. Sixteen RCTs (N = 1536) were included, predominantly among dialysis patients. Fatigue was a primary outcome in only two studies. The meta-analytic findings showed a significant improvement in fatigue following social-psychological interventions (standardised mean difference, SMD = 0.37, p = .001; 95% CI 0.15 to 0.59, I² = 69.1%, p < .001). There was evidence for greater effectiveness of interventions including stress-management/relaxation techniques, evaluated among fatigued samples meeting diagnostic thresholds, against passive/non-active comparison groups. The studies were generally of poor quality, with high heterogeneity, particularly with the number of sessions ranging from 2 to 96. Development and evaluation of a fatigue-specific social-psychological intervention is warranted in this setting.     

Association of HLA-DRB1 and -DQB1 alleles with type 1 (autoimmune) diabetes in African Arabs: systematic review and meta-analysis

Several studies confirmed the association of HLA-DRB1 and -DQB1 alleles with altered risk of type 1 diabetes (T1D). However, data from individual studies based on small sample sizes yielded often conflicting findings in African Arabs. This is a systematic review and meta-analysis aimed at comprehensively evaluating this association with T1D, using molecular HLA data. Relevant studies were identified through systemic search of Medline/PubMed, Cochrane, Science Direct, ResearchGate, and EMBASE databases. Statistical analysis was carried out using RevMan, and Comprehensive Meta-analysis programs. Given the heterogeneity of African Arabs, we also performed subgroup analysis according to ethnicity. Analysis of sensitivity, heterogeneity, and publication bias were performed to validate the outcome of the findings. This meta-analysis included 862 T1DM cases, along with 1,390 normoglycemic control, and comprised ten comparisons. Our study indicates that DRB1*03 (OR = 2.86), DRB1*04 (OR = 2.78), and DQB1*02 (OR = 2.29), are positively associated with increased risk of T1DM, while DRB1*07 (OR = 0.48), DRB1*11 (OR = 0.20), DRB1*13 (OR = 0.47), DRB1*15 (OR = 0.30), DQB1*05 (OR = 0.39), and DQB1*06 (OR = 0.27) were negatively associated with T1D, suggesting a protective role against T1D. This meta-analysis was characterized by low heterogeneity, sensitivity, and publication bias, indicating the robustness and reliability of the results.

Evaluation of targetable biomarkers for chimeric antigen receptor T-cell (CAR-T) in the treatment of pancreatic cancer: a systematic review and meta-analysis of preclinical studies

Abstract

One of the cutting edge techniques for treating cancer is the use of the patient’s immune system to prevail cancerous disease. The versatility of the chimeric antigen receptor (CAR) T-cell approach in conjugation with promising treatments in haematological cancer has led to countless cases of research literature for the treatment of solid cancer. A systematic search of online databases as well as gray literature and reference lists of retrieved studies were carried out up to March 2019 to identify experimental animal studies that investigated the antigens targeted by CAR T-cell for pancreatic cancer treatment. Studies were evaluated for methodological quality using the SYstematic Review Center for Laboratory Animal Experimentation bias risk tool (SYRCLE’s ROB tool). Pooled cytotoxicity ratio/percentage and 95% confidence intervals were calculated using the inverse-variance method while random-effects meta-analysis was used, taking into account conceptual heterogeneity. Heterogeneity was assessed with the Cochran Q statistic and quantified with the I² statistic using Stata 13.0. Of the 485 identified studies, 56 were reviewed in-depth with 16 preclinical animal studies eligible for inclusion in the systematic review and 11 studies included in our meta-analysis. CAR immunotherapy significantly increased the cytotoxicity assay (percentage: 65%; 95% CI: 46%, 82%). There were no evidence for significant heterogeneity across studies [P?=?0.38 (Q statistics), I2?=?7.14%] and for publication bias. The quality assessment of included studies revealed that the evidence was moderate to low quality and none of studies was judged as having a low risk of bias across all domains. CAR T-cell therapy is effective for pancreatic cancer treatment in preclinical animal studies. Further high-quality studies are needed to confirm our finding and a standard approach of this type of studies is necessary according to our assessment.     

Access to chronic disease care in general practice: the acceptability of implementing systematic waiting-room screening using computer-based patient-reported risk status

Background

Routine screening and advice regarding risky lifestyle behaviours is appropriate in the primary care setting, but often not implemented. Routine electronic collection of patients’ self-reported data may streamline the collection of such information.

Aim

To explore the perceptions of GPs and their attending patients regarding the acceptability of waiting-room touchscreen computers for the collection of health behaviour information. Uptake, ease of operation, and the perceived likelihood of future implementation were studied.

Design and setting

Cross-sectional health-risk survey. General practices in metropolitan areas in Australia.

Method

Practices were randomly selected by postcode. Consecutive patients who were eligible to take part in the study were approached in the waiting room and invited to do so. Participants completed the touchscreen health survey. A subsample of patients and GPs completed additional items regarding acceptability.

Results

Twelve general practices participated in the study, with 4058 patients (86%) and 51 of 68 (75%) GPs consenting to complete the health-risk survey, 596 patients and 30 GPs were selected to complete the acceptability survey. A majority of the 30 GPs indicated that the operation of the survey was not disruptive to practice and more than 90% of patients responded positively to all items regarding its operation. More than three-quarters of the patient sample were willing to consider allowing their responses to be kept on file and complete such surveys in the future.

Conclusion

As waiting-room-based collection of this information appears to be both feasible and acceptable, practitioners should consider collecting and incorporating routine patient-reported health behaviours for inclusion in the medical record.     

Severity of illness scoring systems in patients with bacteraemic pneumococcal pneumonia: implications for the intensive care unit care

Severity of illness scoring systems are useful for decisions on the management of patients with community-acquired pneumonia (CAP), including assessing the need for intensified therapy and monitoring, or for intensive care unit (ICU) admission. We compared the accuracy of the Pneumonia Severity Index (PSI), the CURB-65 and CRB-65 score, the modified-American Thoracic Society score (ATS), the IDSA/ATS guidelines and the Pitt Bacteraemia score (PBS) in evaluating severity of illness in 766 patients with bacteraemic pneumococcal pneumonia. We evaluated the sensitivity and specificity, the positive predictive value (PPV) and the negative predictive value (NPV) and the accuracy of the classification in predicting 14-day mortality. The PSI and the IDSA/ATS guidelines were the most sensitive whereas the PBS and modified-ATS scoring systems were the most specific in predicting mortality. The NPV was comparable for all four scoring systems (all above 90%), but the PPV was highest for PBS (54.2%) and lowest for PSI (23.2%). The predictive accuracy and discriminating power as measured by the receiver-operating characteristic (ROC) curve was highest for the PBS. Both the modified-ATS and the PBS scoring systems identified those patients who might benefit most from intensified care and monitoring. The PBS and modified-ATS proved superior to the IDSA/ATS guidelines, CURB-65 and CRB-65 with respect to their specificity and PPV. The low PPV of the PSI rendered it not usable as a parameter for decision-making in severely-ill patients with pneumococcal bacteraemia.     

Antibiotic prescribing for the future: exploring the attitudes of trainees in general practice

Background

Antibiotic resistance is a public health concern worldwide. A high proportion of antibiotics are prescribed in primary care, often for conditions where there is no evidence of benefit. Without a change in these prescribing patterns, resistance will persist as a significant problem in the future. Little is known about how trainees in general practice perceive and develop their prescribing.

Aim

To explore the attitudes of trainees in general practice towards antibiotic use and resistance, and the perceived influences on their prescribing.

Design and setting

A qualitative study of 17 vocational trainees in general practice (GP registrars) in both rural and urban areas in Australia employing semi-structured interviews and a focus group.

Method

Maximum variation purposive sampling of GP registrars from diverse backgrounds and training stages continued until thematic saturation was achieved. Topics of discussion included awareness of antibiotic resistance, use of evidence-based guidelines, and perceived influences on prescribing. Transcribed interviews were coded independently by two researchers. Data collection and analysis were concurrent and cumulative, using a process of iterative thematic analysis.

Results

Registrars were aware of the importance of evidence-based antibiotic prescribing and the impact of their decisions on resistance. Many expressed a sense of dissonance between their knowledge and behaviours. Contextual influences on their decisions included patient and system factors, diagnostic uncertainty, transitioning from hospital medicine, and the habits of, and relationship with, their supervisor.

Conclusion

Understanding how trainees in general practice perceive and develop antibiotic prescribing habits will enable targeted educational interventions to be designed and implemented at a crucial stage in training, working towards ensuring appropriate antibiotic prescribing in the future.
