An observational study of variation in GPs' out-of-hours emergency referrals.

Out-of-hours organisations are responsible for the care of patients 70% of the time, and their GPs act as gatekeepers to secondary care services. This observational study identifies the variations in GPs' out-of-hours referral rates to secondary care and factors that could explain these variations. One hundred and forty-nine GPs who worked in one UK general practice out-of-hours cooperative which served 19 practices with 167 000 registered patients. Data on patients who accessed the out-of-hours service over 3 years (2001-2004) were examined. Factors thought to be predictors of variation in referral rates were investigated using logistic regression analysis. There was a fivefold difference in referral rates between the lowest and highest referring quartiles of GPs (OR [odds ratio] = 4.56, CI [confidence interval] = 3.86 to 5.38). The sex (female) of the clinician, the time of the consultation (11 pm to 7 am), and the place of the consultation (home visit) accounted for some, but not all, of the increased referral rates. A doctor working out-of-hours disproportionately influences the fate of the patient, the number of hospital admissions, and extra costs to the health service. There is a need for follow-up studies to investigate the factors associated with referral behaviour, and how the variation relates to patient factors and the resources available. These findings could be used when planning the staffing of out-of-hours services to optimise appropriate care and minimise patients' exposure to unnecessary intrusive and expensive hospital care.     

Improved health care delivery in an inner-city well-baby clinic run by general practitioners

The delivery of health care has been improved in an inner-city well-baby clinic by staffing the clinic with members of a primary health care team and by offering a therapeutic service together with a preventive service. Over a three-year period attendance at the clinic has doubled and the uptake of immunization has increased. Of children registered with the practice supplying the health care team, 95% are up to date with diphtheria, tetanus and polio immunizations and 93% have been immunized against measles. It is suggested that general practitioners should have greater involvement in the running of well-baby clinics.     

Development of baroreflex and endocrine responses to hypotensive stress in newborn foals and lambs

Objective: The aims of this study were to compare and contrast the development of the cardiac baroreflex and endocrine responses to acute hypotensive stress in healthy newborn pony foals and lambs during the first two weeks of postnatal life. Methods: Under general anaesthesia, seven Welsh pony foals and six Welsh Mountain lambs were catheterised with hind limb artery and vein catheters. Following post-surgical recovery, at 1 week and 2 weeks of age, blood pressures of the animals were raised and lowered acutely by intravenous infusion of phenylephrine and sodium nitroprusside, respectively. During hypotension, blood samples were taken for measurement of plasma hormones associated with activation of the stress axis. Results: Basal arterial blood pressure increased significantly (P<0.05) between week 1 and week 2 in the absence of any significant change in basal heart rate in foals and with a significant reduction in basal heart rate in lambs. In foals, the slope of the heart rate–blood pressure relationship decreased in response to acute hypertension, and it increased in response to acute hypotension, from week 1 to week 2 (all P<0.05). In contrast, in lambs, the slope of the heart rate–blood pressure relationship decreased with both acute hypertension and acute hypotension from week 1 to week 2 (all P<0.05). In foals, there were significant increases in plasma concentrations of noradrenaline, neuropeptide Y (NPY), vasopressin, adrenocorticotrophic hormone (ACTH) and cortisol in response to hypotension (P<0.05). In lambs, there were also significant increases in plasma concentrations of ACTH and cortisol during hypotension. Plasma concentrations of noradrenaline, NPY and vasopressin were not measured during hypotension in lambs. In foals, although the magnitude of the ACTH response to hypotension was smaller at week 2 than week 1, the increment in plasma cortisol was similar in the two age groups. In contrast, in lambs, the profile of both the ACTH and cortisol responses was similar at week 1 and week 2. Conclusion: These data suggest that the increase in basal arterial blood pressure in the foal and the lamb during the first 2 weeks of postnatal life is accompanied by differential maturational changes in the vagal and sympathetic components of the cardiac baroreflex between the two species. These developmental cardiac baroreflex changes occur together with increased adrenocortical responsiveness to acute hypotensive stress, which appears comparatively more mature in lambs than in foals.     

Risk taking in general practice: GP out-of-hours referrals to hospital

Background

Emergency admissions to hospital at night and weekends are distressing for patients and disruptive for hospitals. Many of these admissions result from referrals from GP out-of-hours (OOH) providers.

Aim

To compare rates of referral to hospital for doctors working OOH before and after the new general medical services contract was introduced in Bristol in 2005; to explore the attitudes of GPs to referral to hospital OOH; and to develop an understanding of the factors that influence GPs when they refer patients to hospital.

Design of study

Cross-sectional comparison of admission rates; postal survey.

Setting

Three OOH providers in south-west England.

Method

Referral rates were compared for 234 GPs working OOH, and questionnaires explored their attitudes to risk.

Results

There was no change in referral rates after the change in contract or in the greater than fourfold variation between those with the lowest and highest referral rates found previously. Female GPs made fewer home visits and had a higher referral rate for patients seen at home. One-hundred and fifty GPs responded to the survey. Logistic regression of three combined survey risk items, sex, and place of visit showed that GPs with low ‘tolerance of risk’ scores were more likely to be high referrers to hospital (P<0.001).

Conclusion

GPs'' threshold of risk is important for explaining variations in referral to hospital.     

Endoscopic examination of the larynx: is breathiness dependent on glottic area?

Hypothesis: Hearing tests performed in General Practice at the 3½-year developmental assessment do not correlate with objective measures of otitis media with effusion (OME: ‘glue ear’). Subjects: One hundred and thirty-nine consecutive children attending the 3½-year developmental assessment of four General Practitioners in a single inner-city practice. Outcome measures: The main outcome measure was the presence or absence of effusion as determined by the ‘gold standard’ of type B and C2 tympanograms bilaterally. Independent variables were standard toy test performed by the four GPs, parental assessment of hearing on the test day, the occurrence of two or more documented episodes of otitis media, presence of a smoking parent in the dwelling place and otoscopic findings (glue/no glue) determined by the GP performing the test. Results: The incidence of bilateral OME, as determined by tympanometry, in this population of 3½-year olds was 28%. Forward stepwise linear regression analysis indicated that the only statistically significant independent variable to correlate with tympanometric findings of OME was the GP’s hearing test (P = 0.003). Conclusion: Carefully performed GP hearing tests appear to be good predictors of OME in 3½-year olds, and should continue.
