RESEARCH GEMSGems of <strong>New</strong> <strong>Zealand</strong>Primary Health Care ResearchAll you need <strong>to</strong> know aboutcongestive heart failureThis paper provides an overview of thediagnosis and management of congestiveheart failure (CHF) in primary care.It highlights the distinction betweensys<strong>to</strong>lic (low ejection fraction CHF) anddias<strong>to</strong>lic (preserved ejection fractionCHF) and valvular causes which requiresan echocardiogram. This is essential asthe management is quite clear for sys<strong>to</strong>licdysfunction requiring maximal ACEinhibi<strong>to</strong>rs (e.g. cilazapril 5 mg daily)and maximal beta blockers (me<strong>to</strong>prolol190 mg daily or carvedilol 25 mg twicedaily). If that does not work then spironolac<strong>to</strong>ne25 mg per day and/or digoxin arepossibilities. <strong>The</strong>re is little evidence forthe management of dias<strong>to</strong>lic dysfunction.Arroll B, Doughty R, Andersen V.Investigation and management of congestiveheart failure.

Over70 000 risk assessments were undertakenbetween 2002 and 2009. Pacificpatients tended <strong>to</strong> be risk-assessed fouryears younger than Europeans. Amongthose who were assessed, Pacific menwere 1.5 times as likely <strong>to</strong> smoke asEuropeans. Pacific patients were alsothree times as likely <strong>to</strong> have diabetes andhad significantly higher dias<strong>to</strong>lic bloodpressures and higher CVD risk thanEuropeans. Targeting these modifiablerisk fac<strong>to</strong>rs may help redress some ofthe health disparities between Pacificpeoples and Europeans.Grey C, Wells S, Riddell T, Kerr A, GentlesD, Pylypchuk R, Marshall R, Ameratunga S,Drury P, Elley CR, Kyle C, Exeter D, Jackson R.A comparative analysis of the cardiovasculardisease risk fac<strong>to</strong>r profiles of Pacific peoplesand Europeans living in <strong>New</strong> <strong>Zealand</strong>assessed in routine primary care: PREDICTCVD-11”.

Communitiesof clinical practice are groupsof health professionals who come<strong>to</strong>gether with the specific and commonpurpose of patient care and the studentsjoin these transient communities as participantswho are both peripheral and legitimate.In these groups students learnand internalise the normative professionalvalues and behaviours they witnessand experience within the disciplinaryblock of the medical school and teachinghospital and through their participationlearn how <strong>to</strong> ‘be one of us’.Jaye C, Egan T, Smith-Han K.

Previous turnaroundtime for labora<strong>to</strong>ry results was24–72 hours. Data collected includedtest indication, differential diagnosisand planned patient disposition pre- andpost-POC tests. POC testing significantlyimproved diagnostic certainty,reduced overall hospital admissions by18% and inter-hospital transfers by 62%,resulting in substantial overall savings<strong>to</strong> the health service.Blattner K, Nixon G, Dovey S, Jaye C,Wigglesworth J.

RESEARCH GEMSCommunication skills acquired bymedical students during GP runsUsing both quantitative and qualitativemethods, this study explored what medicalstudents at the University of Otagofelt they were learning about the doc<strong>to</strong>r–patient relationship, compared <strong>to</strong> whatfaculty and clinicians felt they wereteaching. Teaching of relationship skillson hospital wards was highly variable,rarely explicit, and seemed <strong>to</strong> be primarilydependent on role-modelling. <strong>The</strong>tension between service commitmentsand student teaching in hospital-basedattachments seemed <strong>to</strong> contribute <strong>to</strong> aninsufficient focus on students learningabout communication and relationshipskills. In contrast, general practice runsincluded explicit teaching with feedbackthat reinforced skills taught in the preclinicalcurriculum.Egnew T, Wilson H.

Battles were fought overdiagnoses, over occupational health andsafety in the workplace, and over entitlements<strong>to</strong> therapy and income compensation.However, participants were alsobattling <strong>to</strong> maintain their identities ashard workers, while resisting and challengingnormalising technologies of selfand morally charged negative identitiesoffered them by employers, state fundedaccident and injury insurance agencies,and the medical profession. Inherent intheir narratives is a critique of the neoliberalcapitalist political economy thatallows workers’ bodies <strong>to</strong> be exploited(and sacrificed) for employers’ profits.Jaye C, Fitzgerald R. <strong>The</strong> lived politicaleconomy of occupational overuse syndromeamong <strong>New</strong> <strong>Zealand</strong> workers.
