This included new models of care with GPs and others working in new ways with support from secondary care generic 50mg cozaar with mastercard, while also bringing in associated community services purchase cozaar 25 mg with visa, community nursing and district nursing buy cozaar 50 mg visa. Supporting elements included data sharing and use of the BCF to integrate social care. The problems of pressures on general practice, fragmentation and lack of a universal and equitable service provision were further reasons justifying action. In exchange for extra funding and support, the GP practices in the CCG were expected to offer care closer to home, delivering a wider range of tests and investigations in primary care settings, such as electrocardiography, spirometry and insulin initiation. These steps were expected to reduce referrals to secondary care. Each service area, such as diabetes care, chronic obstructive pulmonary disease and asthma, had an associated set of target outcomes. For example, the plan stated that 90% of patients with type 2 diabetes should be managed outside the acute trust. The plans also included a place for appraisal of practices in relation to their conformance. None of these interventions was without controversy. A number of GPs were very reluctant to accept the changes. The leadership skills of the CCG chairperson and accountable officer were very necessary. They undertook institutional work in conceptualising the required nature of the changes and in the creation of new institutional forms in place of long-standing and embedded institutional practices, which tended to emphasise and privilege professional autonomy. The programme included some elements of PPI and, as was indicated in the survey results, clinicians are sometimes leaders of this process, as in this case. Part of this was through ongoing channels, as in the cases of respiratory and mental health, but in addition there were some special stakeholder consultation events. These included talks with the Patients Council and other patient participation groups. The part played by clinicians as front communicators was seen as very important in this context. We encountered similar service redesign programmes in other CCGs, albeit rather less well elaborated and systemic than in this case. In the next section we analyse how various actors sought to lead these initiatives and how actors on the receiving end experienced them and how they responded. Findings from the interviews and observations The focus of attention for this CCG was without doubt on primary care itself. This large measure was because the CCG realised it was inheriting disparate systems and an uneven scope of services across practices as well as uneven levels of quality of service. The incoming leaders of this CCG held no attachment to the inherited systems and felt an urgent and pressing need to resolve the evident issues in primary care provision across its territory.

Assay of Oxalate Oxalate AGT activity in liver biopsy specim ens can be diagnostic in PH 1 even when renal failure prevents analysis of urinary excretion. The gene encoding AGT has been localized to chrom osom e 2q37.

Strategies to prevent calcium oxalate stone formation Ox include a high fluid intake (recommended in all patients), magnesium oxide (because magnesium increases the solubility of calcium oxalate Ox Ox salts), and inorganic phosphate. Lithotripsy or surgery may be neces- Ox sary but do not alter the progression of nephrocalcinosis [12,13]. Ox H em odialysis is superior to peritoneal dialysis in its ability to rem ove oxalate, but neither one is able to m aintain a rate of oxalate rem oval sufficient to keep up with the production rate in Ox patients with PH 1. O nce end-stage renal disease develops, hem o- dialysis does not prevent the progression of system ic oxalosis. In som e patients, renal transplantation accom panied by an aggressive E program of m anagem ent has been followed by a good outcom e for years.
