Characteristics of general practices associated with emergency-department attendance rates: a cross-sectional study

BACKGROUND

Strategies are needed to contain emergency-department attendance. Quality of care in general practice might influence the use of emergency departments, including management of patients with chronic conditions and access to consultations.

AIM

The aim was to determine whether emergency-department attendance rates are lower for practices with higher quality and outcomes framework performance and lower for practices with better patient reported access.

DESIGN

A cross-sectional study.

SETTING

Two English primary-care trusts, Leicester City and Leicestershire County and Rutland, with 145 general practices.

METHOD

Using data on attendances at emergency departments in 2006/2007 and 2007/2008, a practice attendance rate was calculated for each practice. In a hierarchical negative binomial regression model, practice population characteristics (deprivation, proportion of patients aged 65 or over, ethnicity, gender) and practice characteristics (total list size, distance from the emergency department, quality and outcomes framework points, and variables measuring satisfaction with access) were included as potential explanatory variables.

RESULTS

In both years, greater deprivation, shorter distance from the central emergency department, lower practice list size, white ethnicity and lower satisfaction with practice telephone access were associated with higher emergency-department attendance rates.

CONCLUSIONS

Performance as indicated by the quality and outcomes framework did not predict rates of attendance at emergency departments, but satisfaction with telephone access did. Consideration should be given to improving access to some general practices to contain the use of emergency departments.

Multidetector CT imaging of pleura: comparison of two contrast infusion protocols

OBJECTIVES

Imaging of the pleura by multidetector CT (MDCT) can be challenging. There is no clear evidence or guidelines on contrast infusion parameters for imaging pleura. We compared two contrast protocols for assessing pleural pathology on MDCT.

METHODS

This was a prospective study in which consecutive patients with MDCT for suspected pleural disease on chest radiograph were randomised into two groups. The first group received 150 ml of intravenous contrast at a rate of 2.5 ml s(-1) and the second group received 100 ml at 2 ml s(-1). Images were acquired after a 60 s delay. Hounsfield units of the pleura, thoracic aorta, main pulmonary artery, portal vein and superior mesenteric artery were measured and analysed by two independent readers.

RESULTS

40 patients (20 in each group) who had pleural enhancement on MDCT were included for final analysis. The mean pleural enhancement value was 83 HU (Group A) vs 59 HU (Group B) (p = 0.0004). The mean aortic enhancement was 241 HU (A) vs 141 HU (B) (p<0.0001); main pulmonary artery enhancement was 208 HU (A) vs 139 HU (B) (p<0.0002); portal venous enhancement was 169 HU (A) vs 115 HU (B) (p<0.0001); and the superior mesenteric artery enhancement was 215 HU (A) vs 128 HU (B) (p<0.0001).

CONCLUSION

Enhancement of the pleura and major vessels was significantly higher in the group receiving more contrast at a greater infusion rate. This technique of a single scan through the entire pleural surface with a delayed acquisition is promising. When pleural disease is suspected, contrast infusion protocols should be modified to achieve the best results and clinicians should be encouraged to specifically request a "pleural CT".

The potential clinical benefits of medicines optimisation through comprehensive geriatric assessment, carried out by secondary care geriatricians, in a general practice care setting in North Staffordshire, UK: a feasibility study

OBJECTIVES

To evaluate the feasibility and potential clinical benefits of medicines optimisation through comprehensive geriatric assessment (CGA) of frail patients with multiple conditions, by secondary care geriatricians in a general practice care setting.

METHODS

Seven general practitioner (GP) practices in one region of Stoke-on-Trent volunteered to take part. GPs selected patients (n=186) who were local permanent residents, at least 65 years old and on eight or more medications per day. Patients were sent a written invitation outlining the assessment purpose/format. Prior to patient assessments, primary care staff prepared packs detailing patient medical history, recent consultations, current medications, recent laboratory tests and social circumstances. One hour was allocated for the CGA per patient, with one of three geriatricians, to enable sufficient time to explore all relevant aspects. Assessment comprised a full history, thorough clinical examination, assessment of balance and mobility, mental function and information on home environment and support arrangements. After consultation, geriatricians made recommendations regarding further assessments, investigations or medication changes. Geriatricians entered their main findings and recommendations onto a standard template.

RESULTS

In total, 687 recommendations for changes in patients' medication regimens were made for 169 (91%) patients. In 17 (9%) patients there was no recommendation to alter medications. This resulted in an average of four alterations in medication per patient. The predominant changes to medications were to stop medications (34%) or to reduce the dosage (24%). Starting a new medication represented 18% of all the medication changes. Adherence rates to geriatrician medication recommendations were 72% at 6 months and 65% at 12 months.

CONCLUSIONS

CGA of older patients with complex needs, by geriatricians in a general practice care setting, is feasible. Our study demonstrated constructive collaboration between GPs and geriatricians from secondary care, suggesting further studies and clinical trials are feasible and have scope to yield beneficial outcomes.

How should complete lung collapse secondary to primary spontaneous pneumothorax be managed?

Management of primary spontaneous pneumothorax (PSP) depends on the symptoms and size of lung collapse. The British Thoracic Society recommends needle aspiration (NA) for all PSP requiring intervention, followed by intercostal drain (ICD) if NA fails. We compared the role of NA versus ICD as the first step in PSP with 'complete lung collapse'.This was a retrospective observational study of 877 consecutive pneumothorax episodes at University Hospitals of North Midlands, Stoke on Trent, UK. Chest X-ray (CXR) at presentation was reviewed to identify PSP with complete lung collapse. The primary outcome measure was successful lung re-inflation after initial intervention.Two-hundred and sixty-six PSP patients were identified; 69 had complete lung collapse on CXR of which 35 had NA and 34 had ICD. The ICD group had a significantly better immediate success compared with the NA group (62% versus 11%, odds ratio (OR) = 12.5, p<0.0001; after adjustment for potential confounders, OR increased to 26.4, p=0.0001) although long-term outcomes were comparable.There should be clear consensus on definition and management of complete lung collapse. PSP with complete lung collapse could be managed as a separate subgroup where ICD placement is considered to be the first intervention.
