Health disparities, also known as health inequities, are systematic and potentially remediable differences in one or more aspects of health across population groups defined socially, economically, demographically, or geographically. This topic has been the subject of research stretching back at least decades. Reports and studies have delved into how inequities develop in different societies and, with particular regard to health services, in access to and financing of health systems. In this review, we consider empirical studies from the United States and elsewhere, and we focus on how one aspect of health systems, clinical care, contributes to maintaining systematic differences in health across population groups characterized by social disadvantage. We consider inequities in clinical care and the policies that influence them. We develop a framework for considering the structural and behavioral components of clinical care and review the existing literature for evidence that is likely to be generalizable across health systems over time. Starting with the assumption that health services, as one aspect of social services, ought to enhance equity in health care, we conclude with a discussion of threats to that role and what might be done about them.

Aims Deprescribing is the process of reducing or discontinuing medicines that are unnecessary or deemed to be harmful. We aimed to investigate general practitioner (GP) perceived challenges to deprescribing in residential care and the possible enablers that support GPs to implement deprescribing. Methods A qualitative study was undertaken using semi-structured, face-to-face interviews from two cities in New Zealand and a purpose-developed pilot-tested interview schedule. Interviews were recorded with permission and transcribed verbatim. Transcripts were read and re-read and themes were identified with iterative building of a coding list until all data was accounted for. Interviews continued until saturation of ideas occurred. Analysis was carried out with the assistance of a Theoretical Domains Framework (TDF) and constant comparison techniques. Several themes were identified. Challenges and enablers of deprescribing were determined based on participants’ answers. Results Ten GPs agreed to participate. Four themes were identified to define the issues around prescribing for older people, from the GPs’ perspectives. Theme 1, the ‘recognition of the problem’, discusses the difficulties involved with prescribing for older people. Theme 2 outlines the identified behaviour change factors relevant to the problem. Deprescribing challenges were drawn from these factors and summarised in Theme 3 under three major headings; ‘prescribing factors’, ‘social influences’ and ‘policy and processes’. Deprescribing enablers, based on the opinions and professional experience of GPs, were retrieved and summarised in Theme 4. Conclusion The process of deprescribing is laced with many challenges for GPs. The uncertainty of research evidence in older people and social factors such as specialists’ and nurses’ influences were among the major challenges identified. Deprescribing enablers encompassed support for GPs’ awareness and knowledge, improvement of communication between multiple prescribers, adequate reimbursement and pharmacists being involved in the multidisciplinary team.

The majority of older people with chronic diseases are prescribed multiple medicines resulting in polypharmacy. The extrapolation of the ‘single disease model’ represented by disease‐specific guidelines is a major driver for polypharmacy. Polypharmacy is associated with negative health outcomes. Safely reducing or discontinuing harmful medicines, commonly referred to as deprescribing, has been shown to reduce adverse health outcomes, healthcare costs and mortality. However, there are barriers to deprescribing such as time constraints, limited appropriate clinical resources and the influence of multiple prescribers.

Objectives To identify studies of existing instruments available for clinicians to record overall patient preferences and priorities for care, suitable for use in routine primary care practice in patients with multimorbidity. To examine the data for all identified tools with respect to validity, acceptability and effect on health outcomes. Design Systematic Review. Data sources MEDLINE, EMBASE and Cochrane databases, each with a predefined search strategy. Eligibility criteria Citations were included if they reported a tool used to record patient priorities or preferences for treatment, and quantitative or qualitative results following administration of the tool. Results Our search identified 189 potential studies of which 6 original studies and 2 discussion papers were included after screening for relevance. 5 of 6 studies (83%) were of cross-sectional design and of moderate quality. All studies reported on the usability of a tool in order to elicit patient preferences. No studies reported on changes to patient-specific healthcare outcomes as a consequence of recording preferences and priorities. 1 of 6 studies reported on eliciting patient preference in the context of multimorbidity. No studies incorporated patient preferences into an electronic medical record. Conclusions Given the importance of eliciting patient priorities and preferences in providing patient-centred care in the context of multimorbidity and polypharmacy, we found surprisingly few relevant tools. Some aspects of the tools used for single-disease contexts may also be useful in the context of multimorbidity. There is an urgent need to develop ways to make patient priorities explicitly visible in the clinical record and medical decision-making and to test the effect on patient-relevant outcomes.

Objective Recent studies suggest that statins increase the risk of subsequent diabetes with a clear dose response effect. However, patients prescribed statins have a higher background risk of diabetes. This national cohort study aims to provide an estimate of the comparative risks for subsequent development of new-onset diabetes in adults prescribed statins and in those with an already higher background risk on cardiovascular risk-modifying drugs and a control drug. Design Longitudinal cohort study. Setting Use of routinely collected data from a complete national primary care electronic prescription database in New Zealand. Participants 32 086 patients aged between 40 and 60 years in 2005 were eligible and assigned to four non-overlapping groups receiving their first prescription for: (1) diclofenac (healthy population) n=7140; (2) antihypertensives thought likely to induce diabetes (thiazides and β-blockers) n=5769; (3) antihypertensives thought less likely to induce diabetes (ACE inhibitors, angiotensin II receptor blockers, calcium channel blocker) n=6565 and (4) statins n=12 612. Outcome Numbers of first metformin prescriptions were compared between these groups from 2006 to 2011. Results Patients prescribed statins have the highest risk of receiving a subsequent metformin prescription (HR 3.31; 95% CI 2.56 to 4.30; p<0.01), followed by patients prescribed antihypertensives thought less likely to induce diabetes (HR 2.32; 95% CI 1.74 to 3.09; p<0.01) and patients prescribed antihypertensives thought more likely to induce diabetes (HR 1.59; 95% CI 1.15 to 2.20; p<0.01) in the subsequent 6 years of follow-up, when compared to diclofenac. Conclusions These findings further support the link between statin use and new-onset diabetes and suggest that the understanding of diabetes risk associated with different antihypertensive drug classes may bear practice modification. This provides important information for future research, and for prescribers and patients when considering the risks and benefits of different types of cardiovascular risk-modifying drugs.

The paper and editorial on health checks highlight crucial ethical issues.1 2 It is not just the lack of benefit or the harm to patients—who are frightened by their “high risk” and will never think of themselves as healthy again. It is the waste of resources as governments encourage, and sometimes pay, clinicians to screen healthy patients for cardiovascular risk, …

INTRODUCTION Multimorbidity, the co-existence of two or more long-term conditions, is associated with poor quality of life, high health care costs and contributes to ethnic health inequality in New Zealand (NZ). Health care delivery remains largely focused on management of single diseases, creating major challenges for patients and clinicians. AIM To understand the experiences of people with multimorbidity in the NZ health care system. METHODS A questionnaire was sent to 758 people with multimorbidity from two primary health care organisations (PHOs). Outcomes were compared to general population estimates from the NZ Health Survey. RESULTS Participants (n = 234, 31% response rate) reported that their general practitioners (GPs) respected their opinions, involved them in decision-making and knew their medical history well. The main barriers to effective care were short GP appointments, availability and affordability of primary and secondary health care, and poor communication between clinicians. Access issues were higher than for the general population. DISCUSSION Participants generally had very positive opinions of primary care and their GP, but encountered structural issues with the health system that created barriers to effective care. These results support the value of ongoing changes to primary care models, with a focus on patient-centred care to address access and care coordination.
