Effect of an electronic medical record design modification on laxative co-prescribing among hospitalised patients taking opioids: A before-and-after study.

CONTEXT: Constipation occurs in up to 71.7% (33/46) of hospital inpatients taking opioid analgesics. Co-prescribing laxatives with opioid analgesics is recommended to prevent opioid-induced constipation. OBJECTIVES: This study aimed to examine the effect of an electronic medical record (EMR) design modification to increase laxative co-prescribing among hospitalised inpatients taking opioid analgesics. METHODS: In this retrospective 3-month before-and-after study, an EMR modification to improve docusate with sennosides order sentence visibility was implemented on 21 February 2018, at a teaching hospital in Sydney, Australia. The primary outcome was the co-prescription rate of docusate with sennosides within 24-h of the first opioid analgesic administered. International Classification of Diseases 10th Revision Australian Modification diagnosis codes were collected from the EMR. Multivariable logistic regression was performed to determine the impact of the EMR modification on co-prescribing of laxatives with opioid analgesics. RESULTS: Of the 1832 adult inpatients included in the study (51.0% male), 50.5% were admitted before the EMR modification implementation and 49.5% were admitted afterwards. Docusate with sennosides was co-prescribed in 12.5% of patients before and 14.9% of patients after the EMR modification. Although the EMR modification did not change laxative co-prescribing among surgical patients (odds ratio [OR] = 1.1, 95% confidence interval [CI] 0.8-1.6, p = 0.54), a significant increase in co-prescription of docusate with sennosides among aged care patients (OR = 1.8, 95% CI 1.0-3.0, p = 0.03) was observed. CONCLUSIONS: An EMR design modification did not change laxative co-prescribing in hospital inpatients overall. However, the EMR modification was associated with a significant increase in laxative co-prescribing among aged care patients prescribed opioid analgesics.

Akkermansia muciniphila reduces Porphyromonas gingivalis-induced inflammation and periodontal bone destruction.

AIM: Akkermansia muciniphila is a beneficial gut commensal, whose anti-inflammatory properties have recently been demonstrated. This study aimed to evaluate the effect of A. muciniphila on Porphyromonas gingivalis elicited inflammation. MATERIAL AND METHODS: In lean and obese mice, A. muciniphila was administered in P. gingivalis-induced calvarial abscess and in experimental periodontitis model (EIP). Bone destruction and inflammation were evaluated by histomorphometric analysis. In vitro, A. muciniphila was co-cultured with P. gingivalis, growth and virulence factor expression was evaluated. Bone marrow macrophages (BMMϕ) and gingival epithelial cells (TIGK) were exposed to both bacterial strains, and the expression of inflammatory mediators, as well as tight junction markers, was analysed. RESULTS: In a model of calvarial infection, A. muciniphila decreased inflammatory cell infiltration and bone destruction. In EIP, treatment with A. muciniphila resulted in a decreased alveolar bone loss. In vitro, the addition of A. muciniphila to P. gingivalis-infected BMMϕ increased anti-inflammatory IL-10 and decreased IL-12. Additionally, A. muciniphila exposure increases the expression of junctional integrity markers such as integrin-ß1, E-cadherin and ZO-1 in TIGK cells. A. muciniphila co-culture with P. gingivalis reduced gingipains mRNA expression. DISCUSSION: This study demonstrated the protective effects of A. muciniphila administration and may open consideration to its use as an adjunctive therapeutic agent to periodontal treatment.

Rapid response systems: a prospective study of response times.

PURPOSE: The purpose of the study was to evaluate the time taken for delivery of each component of care following patient deterioration and to assess the effect on response times of strategies implemented to improve the system. METHODS: A model identifying the sequence of organizational responses following a patient's unexpected clinical deterioration was developed. The time to key events and interventions from initial deterioration was measured for 3 months in 2005 and again in 2006 at a tertiary care hospital with a rapid response team (RRT) in place. Strategies to improve compliance with the RRT system were introduced between the 2 periods. RESULTS: The number of acute deterioration episodes identified increased (61 episodes in 2005; 154 episodes in 2006), but there was no improvement in response times. The 2 components contributing most frequently to delays were the time for nursing staff to call for assistance and, where needed, for physicians to call for higher-level care. Overall, 26% of episodes in 2006 and 30% in 2005 did not receive medical attention within 30 minutes of acute deterioration. CONCLUSIONS: Significant delays in responding to acute deterioration persist despite strategies to facilitate the functioning of the RRT system. Simple strategies such as policy directives are not sufficient to effect change in complex health care systems.

Estimating the risk of fatal arrhythmia in patients in methadone maintenance treatment for heroin addiction.

AIMS: To estimate risk of death due to cardiac arrhythmia during methadone maintenance treatment. BACKGROUND: There is evidence that methadone prolongs the QT interval, and has been associated with ventricular tachycardia in some individuals. METHODS: We identified 51 deaths occurring during methadone treatment, occurring in a cohort with a defined exposure to methadone treatment. We obtained consent to access coronial records to investigate these in-treatment deaths in detail, to identify potential cases of fatal arrhythmia--those cases in which sudden death occurred without clear evidence of an alternate cause of death. We obtained consent to access clinic records of dosing. Two physicians reviewed the coronial files and circumstances of death. The total number of person-years exposure to methadone treatment was calculated. RESULTS: There were extensive missing data in coronial and clinic files, making definitive assessment difficult in many cases. No definite case of death due to cardiac arrhythmia was identified. There were two cases in which arrhythmia seemed possible, and 10 cases in which arrhythmia could not be excluded. The study covered 14,500 patient-years (pys) in methadone treatment, yielding an estimate from 0 to 0.069 deaths per 100 pys, with a best estimate of fatal arrhythmia occurring at a rate of 0.014 per 100 pys. Overdose is a more common cause of death. Both potential arrhythmias and overdoses were associated with use of other drugs in addition to methadone­usually, prescription drugs or methamphetamine. CONCLUSIONS: The risk of fatal cardiac arrhythmia in methadone maintenance patients appears to be low. The major risk factor for death was use of prescription drugs, and methamphetamine, in addition to methadone.

Comparing retention in treatment and mortality in people after initial entry to methadone and buprenorphine treatment.

UNLABELLED: AIM To compare retention in treatment and mortality among people entering methadone and buprenorphine treatment for opioid dependence. DATA SOURCES: The Pharmaceutical Drugs of Abuse System (PHDAS) database records start- and end-dates of all episodes of methadone and buprenorphine treatment in New South Wales, and the National Death Index (NDI) records all reported deaths. METHODS: Data linkage study. First entrants to treatment between June 2002 and June 2006 were identified from the PHDAS database. Retention in treatment was compared between methadone and buprenorphine. Names were linked to the NDI database, and 'good matches' were identified. Deaths were classified as occurring during induction, maintenance and either post-methadone or post-buprenorphine, depending on the latest episode of treatment prior to death. The numbers of inductions into treatment, of total person-years spent in each treatment, and person-years post-methadone or buprenorphine, were calculated. Risk of death in different periods, and different treatments, was analysed using Poisson regression. RESULTS: A total of 5992 people entered their first episode of treatment-3349 (56%) on buprenorphine, 2643 on methadone. Median retention was significantly longer in methadone (271 days) than buprenorphine (40 days). During induction, the risk of death was lower for buprenorphine (relative risk = 0.114, 95% confidence interval = 0.002-0.938, P = 0.02, Fisher's exact test). Risk of death was lowest during treatment, significantly higher in the first 12 months after leaving both methadone and buprenorphine. Beyond 12 months after leaving treatment, risk of death was non-significantly higher than during treatment. CONCLUSIONS: Buprenorphine was safer during induction. Despite shorter retention in treatment, buprenorphine maintenance was not associated with higher risk of death.

Preventive health reform: what does it mean for public health?

A revitalised public health strategy offers the most sustainable way to address current health inequalities and prevent chronic non-communicable diseases. Success in these goals requires a whole-of-government approach and long-term investments. A sizeable proportion of this investment must be outside the health sector, in the social, economic and environmental fabric of our society. The benefits of the federal government's proposed prevention agenda will only be realised if there is greater clarity about what constitutes preventive health activity, who is responsible for carrying out the preventive agenda, how it is integrated and funded within the health care system, and how prevention outcomes will be measured and evaluated.

Legislative change is associated with improved health status in people with whiplash.

STUDY DESIGN: Interrupted time series. OBJECTIVE: To assess whether a change in legislation improved health status and quality of life for people with whiplash. SUMMARY OF BACKGROUND DATA: Whiplash was the most prevalent injury in a compulsory, fault based, third party motor vehicle insurance scheme in New South Wales, Australia. Legislative change removed financial compensation for "pain and suffering" for whiplash, introduced clinical practice guidelines for its treatment; and changed regulations to permit earlier acceptance of compensation claims, and earlier access to treatment, for all types of injury. METHODS: Three independent groups of people with whiplash were identified from insurance data (before legislative change--the 1999 group and, after legislative change--the 2001 and 2003 groups). Health status was assessed 2 years after injury by a telephone interviewer blinded to the study hypotheses. The main outcome measure was disability, as assessed by the Functional Rating Index (FRI). Pain and health-related quality of life was also assessed. RESULTS: The mean FRI at 2 years after injury was 38.0% (SE, 1.9) for the 1999 group, 31.8% (SE, 2.1) for the 2001 group, and 30.1% (SE, 1.8) for the 2003 group (F = 5.0, P = 0.007). Improvement in secondary outcomes, including pain, also occurred. CONCLUSION: Health status of people with whiplash improved after legislative change. Design of compensation schemes should be undertaken with the understanding that the scheme structure may have substantial effects on the long-term health of injured people.

Challenges in health and health care for Australia.

The next Australian Government will confront major challenges in the funding and delivery of health care. These challenges derive from: Changes in demography and disease patterns as the population ages, and the burden of chronic illness grows; Increasing costs of medical advances and the need to ensure that there are comprehensive, efficient and transparent processes for assessing health technologies; Problems with health workforce supply and distribution; Persistent concerns about the quality and safety of health services; Uncertainty about how best to balance public and private sectors in the provision and funding of health services; Recognition that we must invest more in the health of our children; The role of urban planning in creating healthy and sustainable communities; and Understanding that achieving equity in health, especially for Indigenous Australians, requires more than just providing health care services. The search for effective and lasting solutions will require a consultative approach to deciding the nation's priority health problems and to designing the health system that will best address them; issues of bureaucratic and fiscal responsibility can then follow.

Availability and development of guidelines in a tertiary teaching hospital.

OBJECTIVE: The purpose of this study was to review existing guidelines in clinical departments and describe their characteristics, development and implementation at a large teaching hospital in Sydney, Australia. METHODS: The study was undertaken in two stages. First, from September to November 2005, we reviewed and classified documents from eight departments as clinical practice guidelines (CPGs), clinical procedural protocols (technology and technique) or administrative guidelines. We also collected information about the scope, format and target user of the guidelines. Second, from March to June 2006, we interviewed department staff in seven of eight participating departments about the guidelines' development and implementation. A revised Appraisal of Guidelines Research and Evaluation questionnaire was used to collect data in both stages. RESULTS: A total of 368 of 509 documents reviewed were classified as CPGs. Almost 90% of the CPGs had five or fewer pages; nearly 80% had no references; and 90% had no application tools. The CPGs had been developed locally by each individual department. The departments used various methods to collect evidence. In six (albeit a different six departments in each case) of seven departments, clinicians' clinical experience was used in the analysis of the evidence; informal expert consensus was used for formulating recommendations; internal peer review was the major method used to review the guidelines (after drafting); hard copy of guidelines was the major medium used; and provision of educational material was the major implementation strategy. CONCLUSIONS: There was great variation in the number, availability and presentation of guidelines in the departments. There was a lack of standardized methods and narrow skills representation during guideline development.

Late entry to antenatal care in New South Wales, Australia.

AIMS: This study aimed to assess the prevalence of women who entered antenatal care (ANC) late and to identify factors related to the late entry to ANC in New South Wales (NSW) in 2004. METHODS: The NSW Midwives Data Collection contained data of 85,034 women who gave birth in 2004. Data were downloaded using SAS and transferred to STATA 8.0. Entering ANC after 12 weeks of gestation was classified as late. The Andersen Health Seeking Behaviour Model was used for selection and analyses of related factors. Regression and hierarchical analyses were used to identify significant factors and their relative contributions to the variation of pregnancy duration at entry to ANC. RESULTS: 41% of women commenced ANC after 12 weeks of gestation. Inequality existed between groups of women with predisposing characteristics and enabling resources contributed more to the variation in pregnancy duration at entry to ANC than needs. The groups of women with highest risk were teenagers, migrants from developing countries, women living in Western Sydney, Aboriginal and Torres Strait Islanders, women with three or more previous pregnancies and heavy smokers. The high risk groups with largest number of women were migrants from developing countries and women living in Western Sydney. CONCLUSION: A large number of women in NSW entered ANC late in their pregnancies. Efforts to increase early entry to ANC should be targeted on identified high risk groups of women.

Health care safety: what needs to be done?

Recent MJA editorials assert that Australian hospitals are no safer than they were when the first hospital safety report was published in 1995. Despite many recommendations by several committees and much activity to improve safety over the past decade, we lack concrete evidence that safety and quality of health care have improved. Efforts to promote hospital safety in the United States and the United Kingdom also remain unevaluated. Incentives for safer care have been implemented locally, but not applied to entire health systems. A recent review in Australia has recommended replacing the current Australian Council for Safety and Quality in Health Care with a smaller Commission on Safety and Quality in Health Care. The Commission will link all national safety activity and report annually to Australian health ministers on hospital safety. We need a system that measures quality and safety, and provides financial incentives for safer care. Implementing the national framework for education about patient safety would develop teamwork skills and skills in techniques of continuous improvement. Linked to this, adequate financial support should be available to make safety changes in the health care environment.

Cancellation of operations on the day of intended surgery at a major Australian referral hospital.

OBJECTIVE: To establish the rate of and reasons for cancellations of surgery on the scheduled day in an Australian hospital. DESIGN: Prospective survey. SETTING: Major metropolitan tertiary hospital, 13 May to 15 November 2002. MAIN OUTCOME MEASURES: Proportion of operations cancelled on the day of surgery, obtained each day from the operating theatre list and a separate list of additions and cancellations compiled on the day; reasons for cancellations from the cancellation list, extended or confirmed, as necessary, by questioning of bookings and ward staff, or members of the surgical team; estimated and actual duration of each operation and patient information from hospital clinical records. RESULTS: 7913 theatre sessions were scheduled by 133 surgeons in the study period; 941 of these (11.9%) were cancelled on the day, including 724 of 5472 (13.2%) elective procedures on working weekdays. Main reasons for cancellation were: no theatre time due to over-run of previous surgery (18.7%); no postoperative bed (18.1%); cancelled by patient (17.5%); and change in patient clinical status (17.1%). Procedural reasons (including patient not ready, no surgeon, list error, administrative cause, and communication failure) totalled 21.0%. Ear, nose and throat surgery experienced the most cancellations (19.6%), followed by cardiothoracic surgery (15.8%). CONCLUSIONS: There were five major reasons of similar magnitude for on-the-day surgery cancellations. We estimated that 60% of cancellations of elective procedures were potentially avoidable. Change of one factor leading to cancellation (eg, provision of more postoperative beds) is not likely to lead to improvement unless the other major factors are also tackled.
