Improving hip fracture care: A five-year review of the early contributors to the Australian and New Zealand Hip Fracture Registry.

OBJECTIVE: The aim of this study was to examine temporal trends (2016-2020) in hip fracture care in Australian and New Zealand (ANZ) hospitals that started providing patient-level data to the ANZ Hip Fracture Registry (ANZHFR) on/before 1 January 2016 (early contributors). METHODS: Retrospective cohort study of early contributor hospitals (n = 24) to the ANZHFR. The study cohort included patients aged ≥50 years admitted with a low trauma hip fracture between 1 January 2016 and 31 December 2020 (n = 26,937). Annual performance against 11 quality indicators and 30- and 365-day mortality were examined. RESULTS: Compared to 2016/2017, year-on-year improvements were demonstrated for preoperative cognitive assessment (2020: OR 3.57, 95% confidence interval [95% CI] 3.29-3.87) and nerve block use prior to surgery (2020: OR 4.62, 95% CI 4.17-5.11). Less consistent improvements over time from 2016/2017 were demonstrated for emergency department (ED) stay of <4 h (2017; 2020), pain assessment ≤30 min of ED presentation (2020), surgery ≤48 h (2020) and bone protection medication prescribed on discharge (2017-2020; 2020 OR 2.22, 95% CI 2.03-2.42). The odds of sustaining a hospital-acquired pressure injury increased in 2019-2020 compared to 2016. The odds of receiving an orthogeriatric model of care and being offered the opportunity to mobilise on Day 1 following surgery fluctuated. There was a reduction in 365-day mortality in 2020 compared to 2016 (OR 0.86, 95% CI 0.74-0.98), whereas 30-day mortality did not change. CONCLUSIONS: Several quality indicators improved over time in early contributor hospitals. Indicators that did not improve may be targets for future care improvement activities, including considering incentivised hip fracture care, which has previously been shown to improve care/outcomes. COVID-19 and reporting practices may have impacted the study findings.

The impact of fixation type for intertrochanteric femoral fracture on patient survival.

BACKGROUND: Intramedullary (IM) nail fixation for intertrochanteric fractures is potentially associated with improved postoperative function but may have an increased mortality risk compared to sliding hip screw (SHS) fixation. This study investigated postoperative mortality risk between surgical fixation type for intertrochanteric fracture in patients aged 50 years and older using linked data from the Australian Hip Fracture Registry and National Death Index. METHODS: Descriptive analysis and Kaplan-Meier survival curves performed unadjusted analysis of mortality and fixation type (short IM nail, long IM nail and SHS). Multilevel logistic regression (AMLR) and Cox modelling (CM) performed adjusted analysis of fixation type and mortality following surgery. Instrumental variable analysis (IVA) was conducted to minimize the effect of unknown confounders. RESULTS: The 30-day mortality was 7.1% for short IM, 7.8% for long IM and 7.8% for SHS fixation (P = 0.2). The AMLR demonstrated significant increase in 30-day mortality risk for long IM nail compared to short IM nail (OR = 1.2, 95% CI = 1.0-1.4, P < 0.05) but no significant difference for SHS fixation (OR = 1.1, 95% CI = 0.9-1.3, P = 0.5). No significant difference between groups and postoperative mortality was demonstrated by the CM at 30-days nor 1-year nor by the IVA at 30-days. CONCLUSION: Despite a significant increase in 30-day mortality risk for long IM nail compared to short IM nail fixation in the adjusted analysis, this was not demonstrated in the CM nor IVA indicating the role of confounders influencing the regression findings. There was no significant association in 1-year mortality between long IM nail and SHS compared to short IM nail fixation.

The impact of cement fixation on early mortality in arthroplasty for hip fracture.

Cementing in arthroplasty for hip fracture is associated with improved postoperative function, but may have an increased risk of early mortality compared to uncemented fixation. Quantifying this mortality risk is important in providing safe patient care. This study investigated the association between cement use in arthroplasty and mortality at 30 days and one year in patients aged 50 years and over with hip fracture. This retrospective cohort study used linked data from the Australian Hip Fracture Registry and the National Death Index. Descriptive analysis and Kaplan-Meier survival curves tested the unadjusted association of mortality between cemented and uncemented procedures. Multilevel logistic regression, adjusted for covariates, tested the association between cement use and 30-day mortality following arthroplasty. Given the known institutional variation in preference for cemented fixation, an instrumental variable analysis was also performed to minimize the effect of unknown confounders. Adjusted Cox modelling analyzed the association between cement use and mortality at 30 days and one year following surgery. The 30-day mortality was 6.9% for cemented and 4.9% for uncemented groups (p = 0.003). Cement use was significantly associated with 30-day mortality in the Kaplan-Meier survival curve (p = 0.003). After adjusting for covariates, no significant association between cement use and 30-day mortality was shown in the adjusted multilevel logistic regression (odd rati0 (OR) 1.1, 95% confidence interval (CI) 0.9 to 1.5; p = 0.366), or in the instrumental variable analysis (OR 1.0, 95% CI 0.9 to 1.0, p=0.524). There was no significant between-group difference in mortality within 30days (hazard ratio (HR) 0.9, 95% CI 0.7to 1.1; p = 0.355) or one year (HR 0.9 95% CI 0.8 to 1.1; p = 0.328) in the Cox modelling. No statistically significant difference in patient mortality with cement use in arthroplasty was demonstrated in this population, once adjusted for covariates. This study concludes that cementing in arthroplasty for hip fracture is a safe means of surgical fixation.

Diabetic patient adherence to pathology request completion in primary care.

Objective Little research exists regarding the prevalence of patient non-adherence with completing pathology requests for chronic disease monitoring. The aims of the present study were to determine the extent to which this exists in diabetic patients and to identify possible reasons contributing to this behaviour. Methods Patients diagnosed with type 2 diabetes mellitus were recruited from three general practices with different demographics. Data were collected by recording demographic patient information at the time of visit. In addition, information regarding patient pathology request adherence and the reasons provided when this was not achieved were also noted. These reasons were compared with preconceptions by medical staff in each practice. Results General practitioner perceptions of poor patient adherence to pathology requests were confirmed, with rates of non-adherence up to 31% at one practice site. The primary reasons preventing completion of pathology testing included forgetfulness, time poorness, poor health literacy and, in some cases, language barriers. Conclusion A high proportion of patients do not prioritise the monitoring of their diabetes, potentially because of a lack of understanding of the importance such management has on their health. Further research should be conducted to determine the effect of the implementation of point-of-care testing on patient outcomes in such areas of low non-adherence with disease management. What is known about the topic? Little quantitative information exists regarding the adherence rate of patients to pathology request completion. Without up-to-date pathology results, a barrier is created, preventing accurate medical treatment of the patient's condition because the doctor cannot ascertain a full picture of the patient's current disease state at the time of consultation. What does this paper add? This paper quantifies the rate of non-adherence among three diabetic patient groups at different practice sites, taking into account patient and site demographics. It also confirms patient non-adherence to timely pathology request completion as a prevalent issue of concern at all practice sites recruited. In addition, it looks at reasons why this issue exists as a means of addressing the problem in the future. What are the implications for practitioners? This research may aid practitioners in addressing such issues at a local level within general practice, because reasons creating barriers to successful completion of pathology requests have been identified and potential solutions suggested.
