Outpatient cardiac rehabilitation: Effects on patient improvement outcomes

OBJECTIVE To determine if the Cardiac rehabilitation (CR) program had positive effects on the patient medically as well as effects on pathological risk factors, functional capacity, and mental health; and the extent to which targets for blood pressure (BP) control in patients with hypertension (HT) and diabetes mellitus (DM) are achieved. METHODOLOGY CR participant data was collected from 1st June 2014 until 31st December 2015 (19 months), which included: demographics, medical history, social history, medications, lipid profiles and anthropometric measurements. Additional data was collected on The Patient Health Questionnaire (PHQ-9) factors, and on the participants 6min walk test (6MWT). Study participants were eligible to participate in the study if they attended 10 or more CR program sessions out of 12 at the Calvary Public Hospital Canberra. RESULTS Seventy nine (79) participants participated in the study. Significant reductions in BP (n=79) (p=<0.05), blood LDL cholesterol levels (n=26) (p=<0.05), and improvements in participants PHQ-9 scores (n=79) (p=<0.001), and their 6MWT (n=78) (p=<0.001) were noted. Participants were also able to better manage their medication (p=<0.05). Importantly, results indicated that significant improvements (p=<0.05) were made in DM patients (n=18) diastolic BP, physical ability and depression and anxiety. CONCLUSION A CR program can reduce risk factors associated with CVD, and improves mental health and physical fitness of participants. RESULTS Indicated that the CR program reduces DM patient risk factors through improved physical fitness and reductions in depression and anxiety, leading to reduced risk of future cardiovascular and renal disease.

The Cost-Effectiveness of a Stroke Unit in Providing Enhanced Patient Outcomes in an Australian Teaching Hospital

BACKGROUND Stroke is one of the leading causes of disability and mortality. Patients who receive organized inpatient care in a stroke unit (SU) have better clinical outcomes. However, evidence on the cost analysis of an SU is lacking. The objective of this study was to assess the performance and analyze the cost-effectiveness of an SU. METHODS A retrospective observational study was conducted comparing the acute stroke patient care in a 6-month period before and after the establishment of an acute SU at Calvary Hospital in 2013-2014. RESULTS There were 103 patients included in the pre-SU period, as compared to 186 patients in the post-SU period. In the pre- and post-SU groups, 54 and 87 patients, respectively, had ischemic stroke, with significant trends in improved morbidity and mortality in the post-SU group (P = .01). The average length of stay (LOS) for patients was reduced from 9.7 days to 4.6 days in the post-SU group (P = .001). There was a reduction of cost per admission from

Services aimed at achieving desirable clinical outcomes in patients with chronic kidney disease and diabetes mellitus: A narrative review

AIMS To determine the extent to which targets for blood pressure (BP) (<140.90 mmHg) and random blood glucose level (BGL) (<7.7 mmol/L) control in patients with chronic kidney disease (CKD) are achieved; and the extent clinical inertia affects BP and glucose control in CKD and diabetes mellitus (DM). METHODS Data was collected from the 1st January 2015 until 31st December 2015 on key patient pathology, admission reason, final discharge diagnosis, and information concerning clinical guideline adherence. RESULTS Eighty-seven (n = 87) CKD patients were included. The average hospital BP for all CKD patients was 134.3/73.4 mmHg, adhering to recommendations of <140/90 mmHg. The average CKD patient pre-admission BP was 134.8/72.2 mmHg compared to the discharge BP of 129.8/72.2 mmHg. At admission, 63.3% and 93.1% of patients adhered to systolic and diastolic BP recommendations, which significantly (p = < .05) increased at discharge to a systolic and diastolic BP adherence of 83.9% and 98.8%, respectively. The average random hospital BGL was 7.7 mmol/L, indicating good control, whereas the pre-hospital HbA1c average was 7.58%, indicating poor control (>7.0% >53 mmol/mol). There were 21 cases of clinical inertia, affecting 18 out of 87 patients (20.7%), with significant adverse hospital discharge differences (p = <.05) between clinical inertia and non- clinical inertia patient systolic BP (144.2 vs. 132.8 mmHg), deranged BGL (66.7% vs. 35.3%), and reduction in kidney function (83.3% vs. 30.9%). CONCLUSION Adherence appears to be related to inpatient clinical inertia and outpatient patient health literacy and empowerment.

Hot of Not: Physiological versus Meteorological Heatwaves—Support for a Mean Temperature Threshold

Background This study was aimed at determining the extent to which after-hours diagnostic imaging is appropriate within the case hospitals Emergency Department. This was amid growing concerns of the inappropriateness of some medical investigations within the Australian health-care system. Methods After-hours referral data and patient notes were used in reviewing the clinical case. Diagnostic imaging was deemed appropriate if reflective of clinical guidelines, and if not reflective, whether the investigation changed the patients ongoing management. Results Results indicated that 96.37% of after-hours diagnostic imaging adhered to clinical guidelines and was appropriately requested, with 95.85% changing the ongoing management of the patient. The most sought after diagnostic imaging procedures were Chest X-Ray (30.83%), and CT Brain (16.58%), with 99.16% and 98.44 appropriateness respectively. Chest pain (14.49%) and motor vehicle accidents (8.12%) were the leading reason for ordering after-hours imaging. Conclusion This study provided an Emergency Department example as it relates to after-hours diagnostic imaging appropriateness. This study found that most after-hours referrals were appropriate.

The art of self-knowledge and deduction in clinical practice.

There is a large number of patients with chronic kidney disease (CKD), diabetes mellitus (DM), and hypertension (HT) but whether the targets on blood pressure (BP) control in patients with DM and/or CKD are met is not clear. This narrative review therefore investigated evidence on services aimed at achieving desirable clinical results in patients with CKD and DM, and HT in Australia. Literature pertaining to pathology diagnosis and management of these patients as well as the complexities in management were considered. This involved evidence from PubMed-listed articles published between 1993 and 2016 including original research studies, focusing on randomised controlled trials and prospective studies where possible, systematic and other review articles, meta- analyses, expert consensus documents and specialist society guidelines, such as those from the National Heart Foundation of Australia, American Diabetes Association, the Department of Health, The Royal College of Pathologists of Australasia, and The Australasian College of Emergency Medicine. Based on the literature reviewed, it is yet unknown as to how effective programs, such as diabetes inpatient services, endocrine out-patient services, and cardiac rehabilitation services, are at achieving guideline recommendations. It is also not clear how or whether clinicians are encumbered by complexities in their efforts of adhering to DM, HT, and glucose control recommendations, and the potential reasons for clinical inertia. Future studies are needed to ascertain the extent to which required BP and glucose control in patients is achieved, and whether clinical inertia is a barrier.

Blood glucose and pressure controls in diabetic kidney disease: Narrative review of adherence, barriers and evidence of achievement

The aim of this study was to determine whether a revised heat warning threshold provides an enhanced predictive tool for increases in Emergency Department heat-related presentations in Canberra, Australia. All Emergency Department triage records containing the word “heat”, as well as those diagnosing a heat related illness for the summer periods 2013/2014, 2014/2015, and 2015/2016 were searched. Then a medical record review was conducted to confirm that the patient’s presentation was related to environmental heat, which was defined by the final clinical diagnosis, presentation complaint and details of the patient’s treatment. Researchers then compared this presentation data, to a mean threshold formula. The mean threshold formula included the past three consecutive daily mean temperatures and the last measured temperature upon presentation. This formula was designed to take into account the variance of night-time lows, with concurrent daily ambient temperatures, and was used to determine whether there was a correlation between heat-related presentations and increasing mean temperatures. Heat-related presentations appeared to occur when the mean threshold temperature reached 25 °C (77 °F), with significant increases when the mean threshold reached 30 °C (86 °F). These results confirm that a mean temperature of 30 °C corresponds to a relevant local public health heat-related threat.

Building empathy among the people of an Emergency Department: Staff and patients, a two-way interaction

Clinical reasoning involves interviewing the patient, taking a history, and carefully scrutinising objects in the environment, via a physical examination, and the interpretation of medical results. Developments in medicine are trending towards the routine use of sophisticated diagnostic tools. While important, these trends may be leading clinicians to rely on expensive tests, while not using or improving the art of clinical deduction. The ideal clinician knows themselves and their environment, truly observes, imagines the possibilities, deduces from what they observe, and continually learns. This allows the clinician to use all of their senses, while not primarily relying on a diagnostic test.
