The Waitangi Tribunal in their Wai 2575 Report recommended the establishment of Te Aka Whai Ora (the Māori Health Authority) to remedy some of the contemporary breaches of Te Tiriti o Waitangi (Te Tiriti). Te Aka Whai Ora was the culmination of decades of Māori advocacy for the establishment of independent Māori health leadership, policymaking and commissioning. Under urgency, the new National-led coalition Government passed the Pae Ora (Disestablishment of Māori Health Authority) Amendment Act 2024 in February. In this paper we use Critical Tiriti Analysis (CTA), a five-stage process, to review the extent to which the Act is compliant with the five elements of Te Tiriti (the authoritative Māori text), the preamble, the three written articles and the oral article. We found that the Act had very limited Tiriti compliance and the potential to do great harm. We offered practical suggestions how this could have been avoided.

Aim: Mental health-related emergency department (ED) presentations are steadily increasing, including presentations for both mental health and non-mental health concerns by existing clients of mental health services. The study aim was to examine and compare mental health clients and non-clients' ED presentations, identify data and clinical gaps and make recommendations for improvement.

Method: De-identified 2017/2018 ED data were used to describe presentations for current and recent (within last 5 years) clients of specialist public mental health and addiction services, compared to presentations of non-mental health clients.

Results: Of 49,170 presentations, 18% were by clients of mental health services. Compared to other ED presenters, mental health clients were often younger, female and Māori, required more urgent care and waited longer. Mental health-related International Classification of Diseases (ICD) codes/referrals were most common for presentations by current mental health clients, whereas pain and trauma were often the reason for prior mental health clients' presentations. Discharge diagnoses rarely included self-harm behaviour, and admissions for these clients were more commonly by ED rather than mental health services.

Conclusion: Mental health clients are common in ED. Enhanced mental health data capture and improved systems and processes are needed to ensure that ED staff can better meet their often-complex needs.

Aims: A NZ$5 co-payment prescription charge was removed in July 2023 but may be reinstated. Here we quantify the health impact and cost of not being able to afford this charge.

Methods: We linked New Zealand Health Surveys (2013/2014-2018/2019) to hospitalisation data using data available in Integrated Data Infrastructure (IDI). Cox proportional-hazards models compared time to hospitalisation between those who had faced a cost barrier to collecting a prescription and those who had not.

Results: Of the 81,626 total survey respondents, 72,243 were available for analysis in IDI. A further 516 were excluded to give an analysis dataset of 71,502. Of these, 5,889 (8.2%) reported not collecting a prescription due to cost in the previous year. Among people who faced a cost barrier, 60.0% (95% confidence interval [CI] 58.7-61.2%) were admitted to hospital during the study period, compared to 43.9% (95% CI 43.6-44.3%) of those who did not. Having adjusted for socio-demographic variables, people who faced a cost barrier were 34% (hazard ratio 1.34; 95% CI 1.29-1.39) more likely to be admitted to hospital than those who did not. Annual avoidable hospitalisation costs-were prescription co-payments to remain free-are estimated at $32.4 million per year based on the assumption of a causal relationship between unmet need for prescription medicines and subsequent hospitalisation.

Conclusions: The revenue to the health system from co-payments may be offset by the costs associated with avoidable hospitalisations.

Chronic temporomandibular disorder (cTMD) as a term based on the diagnostic criteria for temporomandibular disorders (DC/TMD) classification refers, in this paper, to the condition listed that has a non-mechanical association without any obvious organic cause. Specifically, this is the condition that falls under the International Classification of Diseases 11th revision (ICD-11) classification of chronic primary and chronic secondary pains. This implies that there is increased responsiveness of nociceptive neurons in the central nervous system, a phenomenon known as central sensitisation. cTMD patients may have their beginning with genetic susceptibility to pain. Although no single gene is exclusively linked to cTMD, various genes associated with nervous and musculoskeletal systems are believed to play a role. Environmental triggers and epigenetic changes are also thought to contribute to cTMD development. The biopsychosocial model emphasises the need to comprehensively address biological, psychological and social factors in cTMD assessment and management. In this study, we leverage the cyclic causation framework within the biopsychosocial model to illuminate the intricate interplay between biological and psychosocial factors in the context of cTMD. The conceptualisation of cTMD involves the dynamic evolution of genetic predispositions, influenced by life events and other biological susceptibilities. These factors collectively contribute to the emergence of nociplastic changes, ultimately manifesting as the distinctive features observed in individuals afflicted with cTMD.

Aims: The aim of this study was to investigate the outcome of common bile duct stones (CBDS) in asymptomatic patients at laparoscopic cholecystectomy (LC) and intra-operative cholangiogram (IOC).

Methods: All patients undergoing LC and IOC at Te Whatu Ora - Health New Zealand Waikato between January 2017 and January 2022 were retrospectively reviewed. Electronic records were screened for asymptomatic CBDS. Exclusion criteria were hyperbilirubinaemia, gallstone pancreatitis, cholangitis and imaging-detected CBDS. IOC reports were reviewed to determine presence of CBDS. A second blinded review was undertaken by a radiologist. Outcomes were use of endoscopic retrograde pancreatography (ERCP), complications and readmission with retained CBDS.

Results: Included were 1,297 patients undergoing LC and IOC. Of these, 150 (24.1%) patients had a positive IOC, of which 58 (38.7%) were asymptomatic. Attempted flushing of CBDS was employed in 49 cases, 10 successfully. Common duct exploration was successful in a further six out of seven cases. Of the remaining 42 patients, 18 were offered ERCP. Seven had no stone at endoscopy. Sixteen had imaging, revealing clear ducts in 14. The remaining two then had ERCP confirming choledocholithiasis. Eight patients were managed expectantly, of whom none required readmission with retained stones.

Conclusion: Rates of retained asymptomatic stones after positive IOC were low. Acknowledging risks associated with intervention and low rates of readmission with retained CBDS, an expectant approach could be more readily considered.
