Foreword The Ntionl Dietes Audit (NDA) continues to provide comprehensive view of Dietes Cre in Englnd nd Wles despite the technicl nd orgnistionl limittions encountered this yer tht hve led to drop in prticiption. 70.6 per cent of GP prctices nd 79 specilist services hve een included cpturing informtion on 2,058,321 people with dietes. Although there is opportunity for improvement everywhere nd vrition etween loclities nd providers remins significnt, the outstnding messge from this report is the need to ddress the sustntilly worse routine cre nd tretment in younger people with Type 1 nd Type 2 dietes nd in people with Type 1 dietes t ll ges. The NDA results hve een consistent in highlighting this issue for severl yers which suggests tht the current systems of cre tht work resonly well for older people do not deliver the sme enefits to younger people with dietes especilly for those ged less thn 40 (pproximtely 130,000). Given the potentil dverse consequences for these younger people of disility nd premture mortlity in middle life, designing etter systems of cre for them would yield considerle helth enefits. This my e n importnt messge for Clinicl Commissioning Groups s they prepre to commission dietes services in Englnd, nd for Locl Helth Bords in Wles. Whtever the systems of cre, successful prtnership etween those with dietes nd those tht deliver cre will remin centrl to improvements. Structured eduction provides people with the tools to mnge their own dietes. Unfortuntely few seem to e offered structured eduction, nd up to three-qurters of those offered do not mnge to ttend. We hve to improve the delivery of structured eduction so tht it is more ville nd ccessile. The recommendtions of this report include improved delivery of structured eduction nd improved cre for younger people with dietes, something tht we hope cn e developed successfully y providers nd commissioners of dietes services in Englnd nd Wles.

Recommendtions We recommend tht ll commissioners, ll dietes leds nd ll GP nd Specilist providers of dietes cre review their results nd consider one or more of the following ctions: Review nd enourcge improvements to systems for providing structured eduction Review nd improve systems for delivering effective cre to younger people with Type 1 nd Type 2 dietes; lern from the est performers Encourge nd support qulity improvement pproches within the ottom 25 per cent of CCGs nd prctices to chieve ll process nd outcome ge results, similr to the middle 50 per cent. These recommendtions re congruent with the NHS Englnd Action for Dietes 1 report pulished erlier this yer.

Executive Summry The Ntionl Dietes Audit (NDA) 2012-2013 Report 1: Cre Processes nd Tretment Trgets, presents findings on cre processes nd tretment trget chievement rtes from 2012-2013. The dt in this report is sed on: Dt recorded on people with dignosed dietes in Englnd nd Wles from the 1st Jnury 2012 to the 31st Mrch 2013. The dt ws collected etween Octoer 2013 nd Jnury 2014 Dt recorded on people with ll types of dietes mellitus, excluding gesttionl dietes, impired glucose tolernce (IGT) nd impired fsting glucose (IFG)4. The Red codes used for the extrction re descried in the 2012-2013 Primry Cre Extrction Specifiction (PCES) ville on the NDA wesite: www.hscic.gov.uk/nd The prevlence nd registrtion sections of the report re sed on dt collections from oth primry nd secondry cre. The reminder of the report (including the ppendices) includes only ptients registered in primry cre to ensure tht the popultion sed denomintors re comprle. Results for individul CCGs nd individul specilist cre units will e pulished seprtely The NDA report 1 covers the provision of core dietes cre for everyone with dietes. This provides clinicl leds nd commissioners with ge, ethnicity nd socil deprivtion relted perspectives cross the whole popultion for which they re responsile. The NDA lso reports to prticipting individul Generl Prctices nd dult specilist services llowing them to enchmrk their cre ginst their peers. The NPDA (Ntionl Peditric Dietes Audit) reports seprtely to individul prticipting peditric dietes centres regrding their provision of dietes cre for the children nd young people ttending their services. Those reviewing the NDA nd NPDA reports side y side need to e wre of these differences ut, eqully, those wnting to get the most complete picture of locl needs nd service provision should consider the two reports together. i Prticiption 2,058,321 people with dietes in Englnd nd Wles; pprecily less thn 2011-2012 (2,473,239) or 2010-2011 (2,235,810) ) due to fctors noted elow ii 70.6 per cent of prctices in Englnd nd Wles (87.9 per cent in 2011-2012; 80.9 per cent in 2010-2011). People with Dietes Dietes prevlence is higher for men thn women. i Becuse the cre of dults nd children with dietes is mixed etween GP services (this includes ALL ptients) nd hospitl, peditric nd community specilist services (these ech include SOME ptients), the different views tht the two ntionl udits NDA nd NPDA give to the providers of the services will inevitly include overlpping ptients. Thus someone with dietes ttending specilist service should lso pper in the relevnt GP report. The NDA integrtes dt from prticipting specilist nd GP services for dults with dietes so tht if cre process or tretment trget is recorded y one ut not the other oth get the complete dt reported ck to them i.e. whole person view. This mkes sense ecuse it reflects the fct tht there is no clinicl vlue in duplicting something crried out elsewhere. The popultion level NDA reports include ll people with dietes in geogrphicl re irrespective of their mix of provider services nd use integrted dt where they re ville. But NPDA runs independently of the NDA nd of GP services so its dt re not integrted mking it possile tht GP reports do not include ll cre processes or tretment trgets mesured in specilist peditric units nd vice vers. Specilist peditric dietes units re primrily responsile for the cre of most children nd young people with dietes nd for the collection of their cre process nd outcome dt. Although GPs do not provide the mjority of cre for children nd young people living with dietes they do prescrie ll their medictions. Therefore it is in this ge group, nd lso dults with Type 1 or complex dietes tht ttend specilist services not prticipting in NDA, where lck of dt integrtion is most likely to result in slightly deficient whole systems view. Furthermore, for under-17s, the ge cut-off for the QOF GP incentive scheme mens tht there is no finncil vlue to the prctice in replicting results from externl services. Nonetheless, ecuse less thn 10.0 per cent of ll people with Type 1 dietes, nd less thn 1.0 per cent of people with dietes in generl re under 17yr, the overll impct on popultion level NDA results is miniml. ii The drop in prticiption in the NDA this yer ws expected due to the restructuring of the NHS strting in April 2013. This hs left oth chllenges nd opportunities for clinicl udit ut undoutedly the orgnistionl trnsition hd disrupted mny well estlished people nd systems. The NDA lso cknowledges the chnges in the governnce lndscpe long with the dded pressures of significnt numers of GP prctices moving clinicl systems ll which dd to the complexities of primry cre dt extrction for ntionl clinicl udit.

Cre processes For ech of the cre processes, nnul completion rtes continue to plteu. In 2012-13, completion of eight cre processes ws 59.9 per cent, compred to 60.5 per cent in 2011 2012 nd 60.6 per cent in 2010 2011 Recorded rtes of completion for ll eight cre processes re: lower for people with Type 1 (41.3 per cent) thn Type 2 dietes (61.9 per cent) nd remin lower even when other fctors, such s ge, gender, BMI, ethnicity nd durtion of dietes re tken into ccount less likely to e chieved y those ged under 40 compred to older people for oth Type 1 nd Type 2 dietes, with those with Type 1 dietes showing igger difference Vrile etween loclities; CCGs/LHBs in the ottom qurter of performers hd completion rtes 11.8 percentge points lower thn those in the top qurter (55.4 per cent vs. 67.2 per cent) unrelted to socil deprivtion It is notle tht only 16 per cent of people with dietes re current smokers compred to the Ntionl Figure of 20 per cent iii 2. Tretment Trgets Concurrent chievement of ll three NICE recommended glucose, lood pressure nd serum cholesterol levels remins t 35.9 per cent (35.9 per cent in 2011-2012; 33.7 per cent in 2010-2011) NICE recommended serum cholesterol <4mmol/l ws recorded in 28.7 per cent of people with Type 1 dietes nd 40.5 per cent of people with Type 2 dietes; serum cholesterol <5mmol/l (QOF incentivised) ws recorded in 70.2 per cent of people with Type 1 dietes nd 76.8 per cent of people with Type 2 dietes Concurrent chievement of ll three NICE tretment trgets (HA 1c <58 mmol/mol + serum cholesterol <5 mmol/mol + BP <140/80) ws recorded for more ptients in some CCGs/LHBs thn others. Those CCGs/LHBs in the ottom qurter of performers were 3.8 percentge points lower thn those in the top qurter (34.1 per cent vs. 37.9 per cent) Achievement of ll three NICE recommended tretment trgets show mrked difference mong the different ge groups; s people get older or if they hve Type 2 dietes they re more likely to hve chieved the tretment trgets. Structured Eduction Very few people with dietes re recorded s hving een offered structured eduction. 3.9 per cent Type 1, 16.7 per cent Type 2 for those who re newly dignosed nd 2.4 per cent Type 1, 6.0 per cent Type 2 for ll people with dietes Even fewer people with dietes re recorded s ttending structured eduction. 0.9 per cent Type 1, 3.6 per cent Type 2 for those who re newly dignosed nd 1.1 per cent Type 1; 1.6 per cent Type 2 for ll people with dietes. NICE recommended glucose control (HA 1c <58mmol/mol) ws recorded in 27.3 per cent of people with Type 1 dietes nd 64.8 per cent of people with Type 2 dietes NICE recommended lood pressure (<140/80) ws recorded in 73.4 per cent of people with Type 1 dietes nd 68.7 per cent of people with Type 2 dietes (NB trget BP in this NDA yer includes Blood pressure less thn or equl to 140/80 rther thn just less thn 140/80 s in previous reports iv ) iii The NDA percentge Includes under 16s, Englnd nd Wles only nd is not directly comprle to the Ntionl figure which covers over 16s only nd Gret Britin. iv A pper detiling the chnges to the methodology cn e found http://www.hscic.gov.uk/pus/methchnges This explins the impct of this chnge to the Blood Pressure Trget nd the All 3 Tretment Trget figures.

Comment It is disppointing ut understndle tht the turulence of the NHS reorgnistion hs undermined the comprehensiveness of this NDA report. This mens tht locl reports will e less comprehensive ut we elieve tht consistency with previous yers in the high level results mens tht the ntionl conclusions hve not een dversely impcted. However we hope tht GP system suppliers will hve completed their upgrdes nd tht locl systems to ensure comprehensive dt sumission will hve recovered in time for the next round in 2015 when the NDA will e endevouring to pulish 2014 2015 reports just 6 months fter the end of the udit yer in Novemer 2015. Nonetheless the 2012 2013 udit pints picture tht hs ecome fmilir in the pst two or three yers nd which we elieve should set the gend for dietes cre improvement y every dietes cre provider, y every clinicl led for dietes services nd y every dietes cre commissioner. It is the continued finding tht younger people with Type 1 or Type 2 dietes nd people with Type 1 dietes t ll ges less often receive ll the nnul cre processes or chieve the sic tretment trgets. Notle lso is the continued low rte of offering nd receiving structured dietes eduction; this is key foundtion of effective self-cre ut presently seems to e ssigned low priority. This yer the Blood Pressure trget hs een minimlly modified from <140/80 to <140/80 to lign with the QOF trget. We were surprised t the resulting size of the difference suggesting tht Blood Pressure mesurement my still e plgued y the long recognised issue of rounding (digit preference). We hve previously highlighted in the NDA report 2 (2011 2012) how lrge the contriution of Hert Filure to premture mortlity so Blood Pressure control is one of the most vlule components of routine dietes cre nd it is therefore essentil for it to e mesured relily. This link etween the effectiveness of routine cre nd complictions is the sis of our concern out the ge inequlity in dietes cre. Though it my e common experience tht it is much more difficult to support younger people nd people with Type 1 dietes ecuse they often hve dietes tht is inherently more difficult to mnge nd lives tht re full of competing priorities the prize of success would e huge. Yet the mount of vrition suggests tht there re lredy some pproches from which we could ll lern. Younger people with dietes who re not chieving tretment trgets contriute disproportionte shre of the urden of dietes disility nd premture mortlity greter focus on designing services to mke them more ppropritely suited to the needs of those who re working, students, nd living full lives needs to e considered. These deductions re, we elieve, reinforced y setting the udit results in the context of the key studies which shped the guidelines on which the mesurements re sed.

How does current dietes cre compre to lndmrk clinicl studies? Current guidelines for the mngement of Dietes hve een shped y numer of lndmrk studies tht identified the influence of lood glucose levels, lood pressure nd sttin mediction in reducing the risk of mcro nd micro vsculr complictions. Differences etween crefully selected tril popultions nd ll people with dietes nd etween pproches to dt is presenttion mke direct ssessments of current cre with reserch studies difficult. However, rod comprisons etween people in the NDA with similr chrcteristics to those recruited for the trils my help inform ssessment of the chievements priorities for improvement in contemporry cre progrmmes. Between 1983 nd 1989 people ged 13 to 39 yers old with Type 1 dietes of etween one nd 15 yers durtion were enrolled in the Dietes Control nd Complictions Tril (DCCT). The findings of this tril nd its follow on oservtionl study, the Epidemiology of Dietes Interventions nd Complictions (EDIC) study, highlighted the reltionship etween lood glucose levels nd risk of micro-vsculr disese (chronic kidney disese nd retinopthy 3 ). After n verge follow up of six nd hlf yers tril people llocted to conventionl tretment (mnging lood glucose levels to prevent symptoms) hd men HA 1c of 76 mmol/mol (9.1 per cent) whilst those in the intensive tretment (iming for HA 1c in the norml rnge) group hd men HA 1c of 56 mmol/mol (7.3 per cent 4 ). A rodly comprle cohort of people with Type 1 dietes from the 2012 2013 NDA cohort hd men HA 1c of 72 mmol/mol (8.7 per cent). The UK Prospective Dietes Study (UKPDS) recruited people ged 25 to 65 yers old with newly dignosed Type 2 dietes etween 1977 nd 1991 5. This study identified tht more intensive mngement of lood glucose in people with Type 2 dietes reduced the future risk of micro- nd mcro-vsculr complictions. It lso highlighted the importnt role of mnging high lood pressure nd cholesterol in this group of people. After 10 yers of follow up the verge HA 1c ws 53mmol/mol (7.0 per cent) in the intensive mngement group compred to 63mmol/mol (7.9 per cent) in the conventionl tretment group 5. A comprle cohort of people in the 2012 2013 NDA cohort hd men HA 1c of 57mmol/mol (7.4 per cent). In this group of people the men systolic lood pressure ws 131.3mmHg, the men distolic lood pressure ws 77.7mmHg nd men totl cholesterol ws 4.5mmol/l. These comprisons highlight the much greter progress tht hs een mde in the mngement of Type 2 dietes thn Type 1 dietes over the pst 15 yers. The tretment outcomes chieved y people with Type 2 dietes cross Englnd nd Wles for HA 1c, lood pressure nd cholesterol re only slightly higher thn those chieved y people in the intensive mngement group of UKPDS. By contrst the smll improvement in men HA 1c mong people with Type 1 dietes leves the men level t 72mmol/mol still firmly in the high risk rnge. We elieve tht improvements will require new pproches to cre especilly for Type 1 dietes.

Introduction The Ntionl Dietes Audit is commissioned y the Helthcre Qulity Improvement Prtnership (HQIP) s prt of the Ntionl Clinicl Audit Progrmme (NCA). HQIP is led y consortium of the Acdemy of Medicl Royl Colleges, the Royl College of Nursing nd Ntionl Voices. Its im is to promote qulity improvement, nd in prticulr to increse the impct tht clinicl udit hs on helthcre qulity in Englnd nd Wles. HQIP holds the contrct to mnge nd develop the NCA Progrmme, comprising more thn 30 clinicl udits tht cover cre provided to people with wide rnge of medicl, surgicl nd mentl helth conditions. The progrmme is funded y NHS Englnd, the Welsh Government nd, with some individul udits, lso funded y the Helth Deprtment of the Scottish Government, DHSSPS Northern Irelnd nd the Chnnel Islnds. The NDA is mnged y the Helth nd Socil Cre Informtion Centre (HSCIC) in prtnership with Dietes UK, supported y Pulic Helth Englnd. This ntionl report from the tenth yer of the udit, presents key findings on key cre processes nd tretment trget chievement rtes from 2012-2013 in ll ge groups in Englnd nd Wles. The report sets out to nswer the following udit questions: Registrtions: Is everyone with dietes dignosed nd recorded on prctice dietes register? Cre Processes: Wht percentge of people registered with dietes received the nine NICE key processes of dietes cre? Tretment Trgets: Wht percentge of people registered with dietes chieved NICE defined tretment trgets for glucose control, lood pressure nd lood cholesterol? The NDA hs een developed to support orgnistions implementing the Ntionl Service Frmework (NSF) for Dietes 6 nd chieving the cre process nd tretment trget stndrds specified in Ntionl Institute for Helth nd Clinicl Excellence (NICE) Clinicl Guidelines (CG15 7, CG66 8 nd CG87 9 ) nd the NICE Dietes in Adults Qulity Stndrds 10. It provides overll, sequentil nd comprtive informtion t GP, hospitl, Clinicl Commissioning Group (CCG; Englnd) or Locl Helth Bord (LHB; Wles) nd ntionl levels. The 2012-2013 NDA report on the complictions of dietes including mortlity will e pulished in erly 2015.

This hs left oth chllenges nd opportunities for clinicl udit ut undoutedly the orgnistionl trnsition hd disrupted mny well estlished people nd systems. The NDA lso cknowledges tht uncertinties induced y the dete out chnges in the governnce lndscpe longside pressures relted to high rtes of chnges nd upgrdes to GP clinicl systems dded to the complexities of primry cre dt extrction during this ntionl clinicl udit yer. So the drop hs een technicl nd orgnistionl. It does not reflect unwillingness to prticipte; only very smll numer (1.3 per cent) of prctices declined inclusion.

Logistic regression nlysis of cre process completion The NDA core udit mesures recorded clinicl prctice ginst NICE clinicl guidelines nd qulity stndrds nd mkes recommendtions for improvement where necessry. All people with dietes should hve equitle ccess to cre so the udit does not stndrdise the udit results to djust for socil nd demogrphic fctors. To investigte whether there re demogrphic nd clinicl fctors tht influence the equity of cre, logistic regression model nlysis hs een used. Logisticl regression nlysis is sttisticl method for investigting the potentil impct of multiple sometimes intercting fctors on n oservtion. In this cse, the possile influence of demogrphic fctors on completion of ech cre process, plus ll 8 cre processes hs een studied. The models ssessed the potentil reltionships of gender, dietes type, ge, ethnicity, deprivtion, ody mss index nd durtion of dietes with cre process completion. The c-sttistic is one method of ssessing model fit. C-sttistic vlues over 0.7 indicte resonle model fit. Six of the nine models (see Appendix 2) hd c-sttistic vlues tht were over 0.7. Using these fctors resonle to strong* model fit ws found for seven cre processes (HA 1c, BP, serum cretinine, cholesterol, smoking, foot surveillnce). Significnt ssocitions included: Dietes type cre process completion ws lower for ptients with Type 1 dietes compred with those with Type 2 dietes Age group cre process completion ws lowest for the youngest ge group (0-49 yers), when compred to the 60-69 ge group. This my e due to higher proportion of younger ptients for those with Type 1 dietes BMI cre process completion ws lowest for the <18.5 group. Agin, this my e due to more Type 1 ptients within this BMI group. Cre process completion for those with BMI of 25 nd over ws higher for ll cre processes, compred with those with BMI of 18.5 to 24.9 Ethnicity cre process completion is lower in nonwhite ethnic groups, most notly for smoking. The lowest BMI group (<18.5) lso hd low completion for recording of smoking sttus. Full results of the multivrite nlysis cn e found in Appendix 2. * Models re typiclly considered to demonstrte resonle ssocitions when the c-sttistic is higher thn 0.7 nd strong when the c-sttistic exceeds 0.8 (Hosmer & Lemeshow, 1989, 2000).

Structured Eduction The NDA hs collected dt on structured eduction in Englnd nd Wles since 2005. NICE guidnce recommend tht people with dietes (Type 1 or Type 2) e offered ptient eduction progrmmes, officilly known s 'structured eduction'. The NDA reports whether there is record tht person with dietes hs een offered or hs ttended structured eduction. When looking t dt for ll people dignosed with dietes, structured eduction ws recorded s eing offered to 2.4 per cent of those with Type 1 dietes nd 6.0 per cent of those with Type 2 dietes, whilst 1.1 per cent of those with Type 1 dietes nd 1.6 per cent of those with Type 2 dietes were recorded s ttending structured eduction. The nlysis in Tle 10 considers structured eduction records in 2012-2013 for ptients dignosed in the sme period.

NDA Methodology Prticiption in the NDA is voluntry; however it does cover 71.1 per cent of the people dignosed with dietes in Englnd nd 69.3 per cent in Wles (when compred with QOF). The NDA collects informtion on ll ptients who hve een dignosed with dietes efore the udit end dte (31st Mrch 2013). Clinicl Commissioning Groups (CCGs), Locl Helth Bords (LHBs), GP prctices nd dult outptient secondry cre units sumit dt out the cre tht is eing delivered for people with dietes in their orgnistion. This will include children tht hve een treted in n dult cre setting. For the full picture on the peditric cre for children with dietes plese refer to the Ntionl Peditric Dietes Audit which is conducted y the Royl College of Peditrics nd Child Helth (RCPCH) 13. In ddition to the dt sumitted y prticipting orgnistions, supplementry informtion relting to specific complictions nd procedures is sourced from the Hospitl Episodes Sttistics (HES) dtse nd the Ptient Episode Dtse for Wles (PEDW). The NDA dt is linked to HES or PEDW dt to the correct ptient record to provide fuller nlysis. Plese note tht for time series nlysis, results re compred with previous yers dt nlysed using NDA methodology.

The model llows n evlution of the strength of the reltionship etween ech of the vriles nd the proility of cre process completion. When modelling dt in this wy the im is to produce model which oth stisfies certin sttisticl criteri nd mintins connection with the rel-world understnding of the ehviours we re trying to explin. The ility of the model to explin the vrition seen in our dt hs een presented s the c-sttistic. This sttistic is the proility tht predicting the outcome is etter thn chnce. The vlues for this mesure rnge from 0.5 to 1.0. A vlue of 0.5 indictes tht the model is no etter thn chnce t mking out whether person will get their cre process nd vlue of 1.0 indictes tht the model perfectly identifies those who will hve the process nd those not. Models re typiclly considered resonle when the c-sttistic is higher thn 0.7 nd strong when the c-sttistic exceeds 0.8*. The choice of explntory vriles cme from consulttion with our clinicl led. All vriles were found to mke significnt improvements to the ility of the model to explin oserved vrition. The vriles included in the models to explin cre process completion were: gender, dietes type, ge group, ethnicity, deprivtion group, ody mss index (BMI), nd durtion of dietes. Following initil nlysis of the dt ll our explntory vriles were grouped into ctegoricl vriles, which group cses into numer of discrete ctegories (for exmple deprivtion is grouped into five ctegories or quintiles). Missing vlues for explntory vriles were included in the models. Excluding missing vlues for explntory vriles cn cuse significnt smple ttrition, since cses re lost if they hve missing vlue for ny one of the relevnt vriles. Hd these vlues een excluded we would hve reduced the precision of estimtes nd my hve introduced is. The model identifies ssocitions, not cuses; in other words, fctors which identify individuls with n incresed or decresed proility of hving cre process in the udit period. These vritions in risk re expressed s odds rtios nd expressed reltive to reference ctegory, with is given vlue of 1. Odds rtios greter thn 1 indicte incresed proility of the cre process eing completed in the group nd odds rtios less thn 1 indicte decresed proility of the cre process eing completed. Also provided re the 95% confidence intervls for the odds rtio. Where the intervl does not include 1, the ctegory is significntly different (P<0.05) from the reference ctegory. *Hosmer & Lemeshow, 1989, 2000 Copyright 2014, Helth nd Socil Cre Informtion Centre, Ntionl Dietes Audit 2012-2013 Report 1: Cre Processes nd Tretment Trgets.
