One of the first patients I encountered was a young man with right-sided thoracic back pain after having spent a day lifting moving boxes. Acute back pain is of course a common reason for people to visit an emergency department, and along with his age, the location and context of the pain seemed fairly typical for muscular strain. But as a junior attending I was appropriately more conservative than how I suspect I would act today. Responding to my nerves, an elicited history of cocaine use and leucocytosis, we ordered an MRI of the back to look for an epidural abscess and treated his pain.\u0000\u0000The MRI was performed and reported as a normal study. While we assessed whether he was comfortable for discharge, I proceeded to focus my attention on other patients who required immediate stabilisation and management. Sometime later during the shift I was suddenly startled by a low-pitched thud near my desk. I looked over and saw someone in a patient gown lying on the floor. Sprinting over to that spot, I soon realised it was this young man collapsed onto the floor in cardiac arrest. During the ongoing resuscitation, the proverbial light bulb went off in my head and I sent the resident physician back to speak with the radiologist again about the MRI, focusing specifically on the aorta. By the time we confirmed a type A aortic dissection ruptured into the right hemithorax and attempted to rush the patient to the operating room, it was too late.\u0000\u0000Despite our best efforts, he died.\u0000\u0000Nothing in my medical training up to that point prepared me for such failure.

After each failure, the narrative is familiar and recited often—continuous quality improvement is invoked, and performance measurement is touted as a core strategy. Yet, does any of this make a difference?\u0000\u0000Almost 20 years ago the Institute of Medicine published ‘To Err is Human’, a widely cited report that highlighted the all-too-frequent occurrence of adverse events, negative and unintended consequences of healthcare.2 An estimated 1 in 10 hospital admissions results in an adverse event3 and 98 000 deaths occur per year as a consequence of adverse events.2 4 In addition to the human cost, adverse events burden the healthcare system—they increase hospital length of stay by an average of 10 days and cost in excess of $414 million per year.5 It is hard to know just how safe care is. Measuring safety is imperfect and there is little evidence that it makes care safer. But we have an ethical imperative to do no harm, which requires us to understand how safe care actually is. Measurement is therefore needed, because after all, we cannot fix or improve what we do not measure.\u0000\u0000Despite several commentaries discussing the advantages of existing methods to measure adverse events, controversy about the best method remains.6–16 Many resources have been devoted to determining the most valid method for detecting adverse events, and even more resources have gone towards implementing these measurement approaches within organisations. Discouragingly, however, these approaches have done little to improve the safety of care.17 18 Unlike previous discussions, we submit that the volume and complexity of patient–healthcare system interactions necessitates the development of new, more efficient yet accurate methods for detecting adverse events …","PeriodicalId":49653,"journal":{"name":"Quality & Safety in Health Care","volume":"29 1","pages":"341 - 344"},"PeriodicalIF":0.0,"publicationDate":"2019-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1136/bmjqs-2019-009824","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41608950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Home care referrals in the USA have increased nearly 60% from 2002 to 2016 resulting in an over 88% increase in spending to over US$18 billion for Medicare beneficiaries.1 In a recent 2015–2016 survey in Canada, an estimated 881 800 households, or just over 6% of all households, used home care services including nursing and personal/home support services.2 Despite the widespread use of home care services in many countries, relatively little is known about how to optimise patient outcomes in home care. Many questions remain about which patients are most likely to benefit, which services (eg, nursing, therapies, personal care) are most beneficial for which patients and what intensity and duration of services are ideal for different patient populations.\u0000\u0000Recently, de Mestral and colleagues identified that home care nursing was associated with lower odds of emergency department (ED)visits and rehospitalisations for patients discharged after elective vascular surgeries (ie, carotid endarterectomy, endovascular aortic aneurysm repair and bypass for lower extremity peripheral arterial disease) in Canada.3 This study is important because it adds to the evidence by examining home care in a population very different from the majority of studies focused on the effect of home care on patient outcomes. Most studies focus on patients with heart failure (HF) and the results have been mixed. One major difference to highlight is that the risk for ED visits and rehospitalisations in patients following an elective vascular surgery procedure is lower compared with patients who have an unplanned HF hospitalisation. The former population would have a lower risk of 30-day readmissions (~6%–19% readmission rate) compared with patients with HF who are readmitted more …","PeriodicalId":49653,"journal":{"name":"Quality & Safety in Health Care","volume":"29 1","pages":"968 - 970"},"PeriodicalIF":0.0,"publicationDate":"2019-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1136/bmjqs-2019-009754","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47308461","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Design Case studies based on three orthopaedic trials funded in sequence by the National Institute for Health Research Health Technology Assessment (HTA) programme. These trials dealt with treatment of fractures of the humerus, radius and ankle, respectively. For each case study, we conducted time-series analyses to examine the relationship between publication of findings and the implementation (or not) of the findings. Results The results of all three trials favoured the less expensive and less invasive option. In two cases, a change of practice, in line with the evidence that eventually emerged, preceded publication.

Conclusions Implementation of results of all three HTA orthopaedic trials favoured the less expensive and less invasive option. In two of the three studies, a change in practice, in line with the evidence that eventually emerged, preceded publication of that evidence. A trend or a change in practice, at around the start of the trial, indicates that the direction of causation opposes our hypothesis that publication of trial findings would lead to changes in practice.

However, there is little objective evidence on the quality of medical records in low and middle-income countries. Objective To provide an unbiased assessment of the quality of medical records for outpatient visits to rural facilities in China. Methods A sample of 207 township health facilities across three provinces of China were enrolled. Unannounced standardised patients (SPs) presented to providers following standardised scripts. Three weeks later, investigators returned to collect medical records from each facility. Audio recordings of clinical interactions were then used to evaluate completeness and accuracy of available medical records. Results Medical records were located for 210 out of 620 SP visits (33.8%). Of those located, more than 80% contained basic patient information and drug treatment when mentioned in visits, but only 57.6% recorded diagnoses. The most incompletely recorded category of information was patient symptoms (74.3% unrecorded), followed by non-drug treatments (65.2% unrecorded). Most of the recorded information was accurate, but accuracy fell below 80% for some items. The keeping of any medical records was positively correlated with the provider’s income (β 0.05, 95% CI 0.01 to 0.09). Providers at hospitals with prescription review were less likely to record completely (β −0.87, 95% CI −1.68 to 0.06). Significant variation by disease type was also found in keeping of any medical record and completeness. Conclusion Despite the importance of medical records for health system functioning, many rural facilities have yet to implement systems for maintaining patient records, and records are often incomplete when they exist. Prescription review tied to performance evaluation should be implemented with caution as it may create disincentives for record keeping. Interventions to improve record keeping and management are needed.","PeriodicalId":49653,"journal":{"name":"Quality & Safety in Health Care","volume":"29 1","pages":"491 - 498"},"PeriodicalIF":0.0,"publicationDate":"2019-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1136/bmjqs-2019-009890","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48529082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Teamwork Shared Mental Models (teamwork-SMMs) are the teams’ organised understanding of individual member’s roles, interactions and behaviours needed to perform a task like hospital discharge. Teamwork-SMMs are linked to team effectiveness in other fields, but have not been readily investigated in healthcare. This study examines teamwork-SMMs to understand how interprofessional teams coordinate care when discharging patients. Methods This mixed methods study examined teamwork-SMMs of inpatient interprofessional discharge teams at a single hospital. For each discharge event, we collected data from the patient and their discharge team (nurse, physician and coordinator) using interviews and questionnaires. We quantitatively determined the discharge teams’ teamwork-SMM components of quality and convergence using the Shared Mental Model Scale, and then explored their relationships to patient-reported preparation for posthospital care. We used qualitative thematic analysis of narrative cases to examine the contextual differences of discharge teams with higher versus lower teamwork-SMMs. Results The sample included a total of 106 structured patient interviews, 192 provider day-of-discharge questionnaires and 430 observation hours to examine 64 discharge events. We found that inpatient teams with better teamwork-SMMs (ie, higher perceptions of teamwork quality or greater convergence) were more effective at preparing patients for post-hospital care. Additionally, teams with high and low teamwork-SMMs had different experiences with team cohesion, communication openness and alignment on the patient situation. Conclusions Examining the quality and agreement of teamwork-SMMs among teams provides a better understanding of how teams coordinate care and may facilitate the development of specific team-based interventions to improve patient care at hospital discharge.","PeriodicalId":49653,"journal":{"name":"Quality & Safety in Health Care","volume":"29 1","pages":"499 - 508"},"PeriodicalIF":0.0,"publicationDate":"2019-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1136/bmjqs-2019-009716","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49096285","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Each year more than half of female homicides are committed by current or former intimate partners or family members.1 Intimate partner violence (IPV), within the domestic violence spectrum, is defined as physical, sexual or emotional violence between partners or former partners.2 It is a serious public health concern with millions of people experiencing violence at the hands of an intimate partner. WHO recognizes IPV as a global issue, prevalent at epidemic proportions in every society, socioeconomic and educational group. According to the National Intimate Partner and Sexual Violence Survey, one in four women and one in nine men in USA have reported severe form of physical violence by an intimate partner during their lifetime.3 Despite the high prevalence and urgency of this critical public health issue, IPV continues to be profoundly underdiagnosed and is considered a persistent hidden epidemic. In addition to physical injuries, IPV has both short-term and long-term negative health consequences including asthma, irritable bowel syndrome, diabetes, poor reproductive health, chronic pain syndrome and mental health problems.4 With victims of IPV seeking medical care more often, healthcare providers can play a vital role in reducing the devastating impact of IPV by representing a trusting source of divulging abuse. The major obstacle to its early detection and intervention is victim under-reporting of physical violence to healthcare providers. Screening for IPV can be an effective tool for detecting and preventing future violence. However, several barriers limit the use and success of these screening programs. Due to shame, privacy, economic dependency, fear of retaliation, legal factors or lack of trust of providers, a patient may not self-report and even fabricate the history of her injury.5 …","PeriodicalId":49653,"journal":{"name":"Quality & Safety in Health Care","volume":"29 1","pages":"241 - 244"},"PeriodicalIF":0.0,"publicationDate":"2019-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1136/bmjqs-2019-009905","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43804627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, posthoc analyses were used to estimate the effectiveness of the QI programme in reducing surgical mortality (30-day and in-hospital mortality). Methods Patients were selected from the Japan Cardiovascular Surgery Database, which includes almost all cardiovascular surgeries in Japan, if they underwent isolated coronary artery bypass graft (CABG), valve or thoracic aortic surgery from 2013 to 2016. Difference-in-difference methods based on a generalised estimating equation logistic regression model were used for pre-post comparison after adjustment for patient-level expected surgical mortality. Results In total, 238 778 patients (10 172 deaths) from 590 hospitals, including 3556 patients seen at 10 hospitals with site visits, were included from January 2013 to December 2016. Preprogramme, the crude surgical mortality for site visit and non-site visit institutions was 9.0% and 2.7%, respectively, for CABG surgery, 10.7% and 4.0%, respectively, for valve surgery and 20.7% and 7.5%, respectively, for aortic surgery. Postprogramme, moderate improvement was observed at site visit hospitals (3.6%, 9.6% and 18.8%, respectively). A difference-in-difference estimator showed significant improvement in CABG (0.29 (95% CI 0.15 to 0.54), p<0.001) and valve surgery (0.74 (0.55 to 1.00); p=0.047). Improvement was observed within 1 year for CABG surgery but was delayed for valve and aortic surgery. During the programme, institutions did not refrain from surgery. Conclusions Combining traditional site visits with modern database methodologies effectively improved surgical mortality in Japan. These universal methods could be applied via a similar approach to contribute to achieving QI in surgery for many other procedures worldwide.","PeriodicalId":49653,"journal":{"name":"Quality & Safety in Health Care","volume":"29 1","pages":"560 - 568"},"PeriodicalIF":0.0,"publicationDate":"2019-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1136/bmjqs-2019-009955","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49374929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
