Impact of financial incentives for primary care to give long acting reversible contraceptive advice

Background

Long acting reversible contraceptives (LARC) are cost-effective but uptake remains poor even in high income settings. In 2009/10, a pay-for-performance (P4P) scheme in the United Kingdom was introduced for primary care physicians to offer advice about LARC to women attending for contraceptive care. We examined the equity and impact of this scheme on LARC uptake and abortions

Methods

We examined records of women aged 13 to 54 years registered with a primary care practice in the UK Clinical Practice Research Datalink from 2004/05 to 2013/14. We used interrupted time series analysis to examine trends in annual LARC and non-LARC hormonal contraception (NLHC) uptake and abortion rates, stratified by age, region and deprivation groups, before and after P4P was introduced in 2009/10.

Results

LARC uptake among women of all ages increased immediately after P4P with step change of 5.36 per 1,000 women (95% CI 5.26 to 5.45). Largest increase was in women aged 20 to 24 years (8.40, 8.34 to 8.47). NLHC uptake fell in all women with a step change of -22.9 (-24.5 to -21.2). Among LARC methods, contraceptive injection and implant had the greatest increase after P4P; step changes were 1.68 (1.67 to 1.70) and 1.64 (1.63 to 1.65) respectively. Abortion rates fell across all 12 regions in UK and in all women immediately after P4P with a step change of -2.28 (-2.99 to -1.57). The largest falls occurred in women aged 13 to 19 years (step change -5.04, -7.56 to -2.51) and women from the most deprived group (step change -4.40, -6.89 to -1.91).

Conclusions

Pay-for-performance scheme for primary care physicians to give LARC advice to women attending for contraception was associated with desirable impact and equity of LARC prescriptions and abortion.

LARC uptake increased in women of all ages, especially 13-19 and 20-24 years. Abortion rates fell in all UK regions and age groups, particularly 13-19 and 20-24 years and those from deprived quintile.

Perioperative intravenous contrast administration and the incidence of acute kidney injury after major gastrointestinal surgery: prospective, multicentre cohort study

BACKGROUND

This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery.

METHODS

This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery.

RESULTS

A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498).

CONCLUSION

There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Steroid dependency and trends in prescribing for inflammatory bowel disease - a 20-year national population-based study

BACKGROUND

It is unclear whether adherence to prescribing standards has been achieved in inflammatory bowel disease (IBD).

AIM

To determine how prescribing of 5-aminosalicylates (5-ASAs), steroids and thiopurines has changed in response to emerging evidence.

METHODS

We examined trends in oral and topical therapies in 23 509 incident IBD cases (6997 with Crohn's disease and 16 512 with ulcerative colitis) using a nationally representative sample between 1990 and 2010. We created five eras according to the year of diagnosis: era 1 (1990-1993), era 2 (1994-1997), era 3 (1998-2001), era 4 (2002-2005) and era 5 (2006-2010). We calculated the proportion of patients treated with prolonged 5-ASAs (>12 months) and steroid dependency, defined as prolonged steroids (>3 months) or recurrent (restarting within 3 months) steroid exposure. We calculated the cumulative probability of receiving each medication using survival analysis.

RESULTS

Half of the Crohn's disease patients were prescribed prolonged oral 5-ASAs during the study, although this decreased between era 3 and 5 from 61.8% to 56.4% (P = 0.002). Thiopurine use increased from 14.0% to 47.1% (P < 0.001) between era 1 and 5. This coincided with a decrease in steroid dependency from 36.5% to 26.8% (P < 0.001) between era 1 and 2 and era 4 and 5 respectively. In ulcerative colitis, 49% of patients were maintained on prolonged oral 5-ASAs. Despite increasing thiopurine use, repeated steroid exposure increased from 15.3% to 17.8% (P = 0.02) between era 1 and 2 and era 4 and 5 respectively.

CONCLUSIONS

Prescribing in clinical practice insufficiently mirrors the evidence base. Physicians should direct management towards reducing steroid dependency and optimising 5-ASA use in patients with IBD.

Impact of early thiopurines on surgery in 2770 children and young people diagnosed with inflammatory bowel disease: a national population-based study

BACKGROUND

The role of early thiopurine treatment in inflammatory bowel disease (IBD) is unproven.

AIM

To quantify the impact of timing and duration of thiopurines on the risk of first surgery in children and young people with IBD using a population-based cohort.

METHODS

We constructed an incident cohort of children and young people aged <25 years, diagnosed with Crohn's disease (CD) or ulcerative colitis (UC) from 1990 to 2009. We used Cox proportional hazards modelling to determine the impact of early thiopurine use, commenced within a year of diagnosis on risk of first surgery.

RESULTS

We identified 1595 and 1175 incident cases of CD and UC respectively with a mean length of follow-up of 4.3 years/person. There were 216 (13.5%) and 73 (6.2%) surgeries for CD and UC patients between 1990 and 2009 respectively. In CD among thiopurine users, the absolute risk of surgery at 5 years for early thiopurine use vs. late was 15.3% (95% CI: 10.5-22.1) vs. 22.1% (95% CI: 18.1-26.9) respectively. After adjustment, the early use of thiopurines was associated with a reduction in risk of first surgery of 39% (HR 0.61, 95% CI: 0.41-0.91) over the 20-year study period. In UC, early thiopurine use offered no additional benefit.

CONCLUSIONS

In Crohn's disease, early treatment with thiopurines in children and young people is associated with an appreciable reduction in the risk of surgery, but early treatment does not reduce surgical risk in UC.

The impact of timing and duration of thiopurine treatment on colectomy in ulcerative colitis: a national population-based study of incident cases between 1989-2009

BACKGROUND

The role of thiopurines in altering the risk of colectomy in ulcerative colitis (UC) remains unclear.

AIMS

To examine predictors of colectomy in UC and determine the impact of thiopurines on the risk of colectomy.

METHODS

We constructed a population-based cohort of incident cases of UC in the United Kingdom between 1989 and 2009. We determined trends in thiopurine usage and colectomy for three defined cohorts: era 1 (1989-1995), era 2 (1996-2002), era 3 (2003-2009). We used Cox regression to determine predictors of colectomy and quantified the impact of duration and timing of thiopurine use on the risk of colectomy.

RESULTS

We identified 8673 incident cases of UC. 5-year colectomy rates increased from 4.2%, 5.1% to 6.9% (P = 0.001) for era 1, era 2 and era 3, respectively, despite increasing thiopurine use. This was not significant after adjustment for predictors of colectomy (P = 0.06). There was a higher risk of colectomy in men (HR 1.44, 95% CI: 1.19-1.73), those diagnosed at an early age (HR 1.35, 95% CI: 1.04-1.75; 16-24 vs. 25-64) and early steroid users (HR 1.94, 95% CI: 1.59-2.37). 5-ASA users were less likely to require a colectomy (HR 0.35, 95% CI: 0.28-0.44). Amongst thiopurine users, those treated for greater than 12 months had a 71% reduction in risk of colectomy (HR 0.29, 95% CI: 0.21-0.40). Early thiopurines offered no additional benefit.

CONCLUSIONS

Thiopurine exposure for greater than 12 months reduces the likelihood of colectomy by 71%. Young men and those requiring steroids within 3 months of diagnosis are at greatest risk of colectomy, and most likely to benefit from sustained thiopurine use.

Does higher quality of primary healthcare reduce hospital admissions for diabetes complications? A national observational study

AIM

To determine if hospital admission rates for diabetes complications (acute complications, chronic complications, no complications and hypoglycaemia) were associated with primary care diabetes management.

METHODS

We performed an observational study in the population in England during the period 2004-2009 (54 741 278 people registered with 8140 general practices). We used multivariable negative binomial regression to model the associations between indirectly standardized hospital admission rates for complications and primary healthcare quality, supply and access indicators, diabetes prevalence and population factors.

RESULTS

In multivariate regression models, increasing deprivation (incidence rate ratio: 1.0154; P < 0.001, 95% CI 1.0141-1.0166) and diabetes prevalence (incidence rate ratio: 1.0956; P < 0.001, 95% CI 1.0677-1.1241) were risk factors for admission, while most healthcare covariates, i.e. a larger practice population (incidence rate ratio 0.9999, P = 0.013, 95% CI 0.9999-0.9999), better patient-perceived urgent and non-urgent access to primary care (incidence rate ratio: 0.9989, P = 0.023; 95% CI 0.9979-0.9998 and incidence rate ratio: 0.9988; P = 0.003, 95% CI 0.9980-0.9996, respectively) and better HbA1c target achievement (incidence rate ratio: 0.9971; P < 0.001, 95% CI 0.9958-0.9984), were protective. Diabetes admissions decreased significantly during the period 2004-2009.

CONCLUSIONS

After controlling for population factors, better scheduled primary care access and glycaemic control were associated with lower hospital admission rates across most complications. There is little rationale to restrict primary care-sensitive condition definitions to acute complications. They should be revised to improve the usefulness of hospital admission data as an outcome measure, and to facilitate international comparisons. The risk of emergency hospital admission should be monitored routinely.

Diabetes or war? Incidence of and indications for limb amputation in Lebanon, 2007

Chronic diseases such as diabetes and vascular disease are a major public health problem in Lebanon, where primary care is not well developed. This study aimed to describe the incidence and indications for limb amputation in Lebanon and identify associated factors (age, sex, level of surgery, length of hospital stay). There were 1.6 amputations per 10 000 persons. The rate of amputation was highest in southern Lebanon at 3.8 per 10 000. The most important indication for surgery was diabetes (59%). Diabetic patients were older (mean age 73 years versus 30 years), more likely to have major surgery (OR = 7.87; 95% CI: 2.83-21.9) and stay in hospital longer (RR = 4.56, 95% CI: 2.41-8.64) than patients with trauma-related amputation. Diabetes prevention, detection and management should be prioritized in any attempt to reduce the current incidence of amputation in Lebanon.

New developments in the diagnostics for the fusion products on JET in preparation for ITER (invited)

Notwithstanding the advances of the past decades, significant developments are still needed to satisfactorily diagnose “burning plasmas.” D–T plasmas indeed require a series of additional measurements for the optimization and control of the configuration: the 14 MeV neutrons, the isotopic composition of the main plasma, the helium ash, and the redistribution and losses of the alpha particles. Moreover a burning plasma environment is in general much more hostile for diagnostics than purely deuterium plasmas. Therefore, in addition to the development and refinement of new measuring techniques, technological advances are also indispensable for the proper characterization of the next generation of devices. On JET an integrated program of diagnostic developments, for JET future and in preparation for ITER, has been pursued and many new results are now available. In the field of neutron detection, the neutron spectra are now routinely measured in the energy range of 1–18 MeV by a time of flight spectrometer and they have allowed studying the effects of rf heating on the fast ions. A new analysis method for the interpretation of the neutron cameras measurements has been refined and applied to the data of the last trace tritium campaign (TTE). With regard to technological upgrades, chemical vapor deposition diamond detectors have been qualified both as neutron counters and as neutron spectrometers, with a potential energy resolution of about one percent. The in situ calibration of the neutron diagnostics, in preparation for the operation with the ITER-like wall, is also promoting important technological developments. With regard to the fast particles, for the first time the temperature of the fast particle tails has been obtained with a new high purity Germanium detector measuring the gamma emission spectrum from the plasma. The effects of toroidal Alfven eigenmodes modes and various MHD instabilities on the confinement of the fast particles have been determined with a combination of gamma ray cameras, neutral particle analyzers, scintillator probe, and Faraday cups. From a more technological perspective, various neutron filters have been tested to allow measurement of the gamma ray emission also at high level of neutron yield.

The effect of the EWTD on training in general surgery: an analysis of electronic logbook records

The introduction of time-limited surgical training in the UK in 1994 following the Calman report raised concerns over the hands-on experience of trainees, heightened by the hours reduction demanded by the New Deal. From 1994, junior doctors' on-duty hours of work for hard-pressed posts were targeted to a limit of 56 hours but SpRs were allowed a voluntary extension from 73 on-duty hours to a maximum of 83 hours per week. By 1995 concern was being expressed at the reduction in training time and continuity of patient care and although calls for more targeted training were made, evidence of a negative impact on training has continued to surface.
