Adverse events in psychiatry: a national cohort study in Sweden with a unique psychiatric trigger tool.

BACKGROUND: The vast majority of patient safety research has focused on somatic health care. Although specific adverse events (AEs) within psychiatric healthcare have been explored, the overall level and nature of AEs is sparsely investigated. METHODS: Cohort study using a retrospective record review based on a two-step trigger tool methodology in the charts of randomly selected patients 18 years or older admitted to the psychiatric acute care departments in all Swedish regions from January 1 to June 30, 2017. Hospital care together with corresponding outpatient care were reviewed as a continuum, over a maximum of 3 months. The AEs were categorised according to type, severity and preventability. RESULTS: In total, the medical records of 2552 patients were reviewed. Among the patients, 50.4% were women and 49.6% were men. The median (range) age was 44 (18-97) years for women and 44.5 (18-93) years for men. In 438 of the reviewed records, 720 AEs were identified, corresponding to the AEs identified in 17.2% [95% confidence interval, 15.7-18.6] of the records. The majority of AEs resulted in less or moderate harm, and 46.2% were considered preventable. Prolonged disease progression and deliberate self-harm were the most common types of AEs. AEs were significantly more common in women (21.5%) than in men (12.7%) but showed no difference between age groups. Severe or catastrophic harm was found in 2.3% of the records, and the majority affected were women (61%). Triggers pointing at deficient quality of care were found in 78% of the records, with the absence of a treatment plan being the most common. CONCLUSIONS: AEs are common in psychiatric care. Aside from further patient safety work, systematic interventions are also warranted to improve the quality of psychiatric care.

A National Study of Patient Safety Culture in Hospitals in Sweden.

OBJECTIVE: Using the Hospital Survey on Patient Culture, our aim was to investigate the patient safety culture in all Swedish hospitals and to compare the culture among managers, physicians, registered nurses, and enrolled nurses and to identify factors associated with high overall patient safety. METHODS: The study used a correlational design based on cross-sectional surveys from health care practitioners in Swedish health care (N = 23,781). We analyzed the associations between overall patient safety (outcome variable) and 12 culture dimensions and 5 background characteristics (explanatory variables). Simple logistic regression analyses were conducted to determine the bivariate association between each explanatory variable and the outcome variable. The explanatory variables were entered to determine the multivariate associations between the variables and the outcome variable. RESULTS: The highest rated culture dimensions were "teamwork within units" and "nonpunitive response to error," and the lowest rated dimensions were "management support for patient safety" and "staffing." The multivariate analysis showed that long professional experience (>15 years) was associated with increased probability for high overall patient safety. Compared with general wards, the probability for high overall patient safety was higher for emergency care but lower for psychiatric care. The probability for high overall patient safety was higher for both enrolled nurses and physicians compared with managers. CONCLUSIONS: The safety culture dimensions of the Hospital Survey on Patient Culture contributed far more to overall patient safety than the background characteristics, suggesting that these dimensions are very important in efforts to improve the overall patient safety culture.

The professional culture among physicians in Sweden: potential implications for patient safety.

BACKGROUND: Patient safety culture, i.e. a subset of an organization's culture, has become an important focus of patient safety research. An organization's culture consists of many cultures, underscoring the importance of studying subcultures. Professional subcultures in health care are potentially important from a patient safety point of view. Physicians have an important role to play in the effort to improve patient safety. The aim was to explore physicians' shared values and norms of potential relevance for patient safety in Swedish health care. METHODS: Data were collected through group and individual interviews with 28 physicians in 16 semi-structured interviews, which were recorded and transcribed verbatim before being analysed with an inductive approach. RESULTS: Two overarching themes, "the competent physician" and "the integrated yet independent physician", emerged from the interview data. The former theme consists of the categories Infallible and Responsible, while the latter theme consists of the categories Autonomous and Team player. The two themes and four categories express physicians' values and norms that create expectations for the physicians' behaviours that might have relevance for patient safety. CONCLUSIONS: Physicians represent a distinct professional subculture in Swedish health care. Several aspects of physicians' professional culture may have relevance for patient safety. Expectations of being infallible reduce their willingness to talk about errors they make, thus limiting opportunities for learning from errors. The autonomy of physicians is associated with expectations to act independently, and they use their decisional latitude to determine the extent to which they engage in patient safety. The physicians perceived that organizational barriers make it difficult to live up to expectations to assume responsibility for patient safety. Similarly, expectations to be part of multi-professional teams were deemed difficult to fulfil. It is important to recognize the implications of a multi-faceted perspective on the culture of health care organizations, including physicians' professional culture, in efforts to improve patient safety.

Incidence of adverse events in Sweden during 2013-2016: a cohort study describing the implementation of a national trigger tool.

OBJECTIVES: To describe the implementation of a trigger tool in Sweden and present the national incidence of adverse events (AEs) over a 4-year period during which an ongoing national patient safety initiative was terminated. DESIGN: Cohort study using retrospective record review based on a trigger tool methodology. SETTING AND PARTICIPANTS: Patients ≥18 years admitted to all somatic acute care hospitals in Sweden from 2013 to 2016 were randomised into the study. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary outcome measure was the incidence of AEs, and secondary measures were type of injury, severity of harm, preventability of AEs, estimated healthcare cost of AEs and incidence of AEs in patients cared for in another type of unit than the one specialised for their medical needs ('off-site'). RESULTS: In a review of 64 917 admissions, the average AE rates in 2014 (11.6%), 2015 (10.9%) and 2016 (11.4%) were significantly lower than in 2013 (13.1%). The decrease in the AE rates was seen in different age groups, in both genders and for preventable and non-preventable AEs. The decrease comprised only the least severe AEs. The types of AEs that decreased were hospital-acquired infections, urinary bladder distention and compromised vital signs. Patients cared for 'off-site' had 84% more preventable AEs than patients cared for in the appropriate units. The cost of increased length of stay associated with preventable AEs corresponded to 13%-14% of the total cost of somatic hospital care in Sweden. CONCLUSIONS: The rate of AEs in Swedish somatic hospitals has decreased from 2013 to 2016. Retrospective record review can be used to monitor patient safety over time, to assess the effects of national patient safety interventions and analyse challenges to patient safety such as the increasing care of patients 'off-site'. It was found that the economic burden of preventable AEs is high.

Exploring similarities and differences in hospital adverse event rates between Norway and Sweden using Global Trigger Tool.

OBJECTIVES: In this paper, we explore similarities and differences in hospital adverse event (AE) rates between Norway and Sweden by reviewing medical records with the Global Trigger Tool (GTT). DESIGN: All acute care hospitals in both countries performed medical record reviews, except one in Norway. Records were randomly selected from all eligible admissions in 2013. Eligible admissions were patients 18 years of age or older, undergoing care with an in-hospital stay of at least 24 hours, excluding psychiatric and care and rehabilitation. Reviews were done according to GTT methodology. SETTING: Similar contexts for healthcare and similar socioeconomic and demographic characteristics have inspired the Nordic countries to exchange experiences from measuring and monitoring quality and patient safety in healthcare. The co-operation has promoted the use of GTT to monitor national and local rates of AEs in hospital care. PARTICIPANTS: 10 986 medical records were reviewed in Norway and 19 141 medical records in Sweden. RESULTS: No significant difference between overall AE rates was found between the two countries. The rate was 13.0% (95% CI 11.7% to 14.3%) in Norway and 14.4% (95% CI 12.6% to 16.3%) in Sweden. There were significantly higher AE rates of surgical complications in Norwegian hospitals compared with Swedish hospitals. Swedish hospitals had significantly higher rates of pressure ulcers, falls and 'other' AEs. Among more severe AEs, Norwegian hospitals had significantly higher rates of surgical complications than Swedish hospitals. Swedish hospitals had significantly higher rates of postpartum AEs. CONCLUSIONS: The level of patient safety in acute care hospitals, as assessed by GTT, was essentially the same in both countries. The differences between the countries in the rates of several types of AEs provide new incentives for Norwegian and Swedish governing bodies to address patient safety issues.

Adverse events in orthopedic care identified via the Global Trigger Tool in Sweden - implications on preventable prolonged hospitalizations.

BACKGROUND: The national incidence of adverse events (AEs) in Swedish orthopedic care has never been described. A new national database has made it possible to describe incidence, nature, preventability and consequences of AEs in Swedish orthopedic care. METHODS: We used national data from a structured two-stage record review with a Swedish modification of the Global Trigger Tool. The sample was 4,994 randomly selected orthopedic admissions in 56 hospitals during 2013 and 2014. The AEs were classified according to the Swedish Patient Safety Act into preventable or non-preventable. RESULTS: At least one AE occurred in 733 (15 %, 95 % CI 13.7-15.7) admissions. Of 950 identified AEs, 697 (73 %) were judged preventable. More than half of the AEs (54 %) were of temporary nature. The most common types of AE were healthcare-associated infections and distended urinary bladder. Patients ≥65 years had more AEs (p < 0.001), and were more often affected by pressure ulcer (p < 0.001) and urinary tract infections (p < 0.01). Distended urinary bladder was seen more frequently in patients aged 18-64 years (p = 0.01). Length of stay was twice as long for patients with AEs (p < 0.001). We estimate 232,000 extra hospital days due to AEs during these 2 years. The pattern of AEs in orthopedic care was different compared to other hospital specialties. CONCLUSIONS: Using a national database, we found AEs in 15 % of orthopedic admissions. The majority of the AEs was of temporary nature and judged preventable. Our results can be used to guide focused patient safety work.

Preventable Adverse Events in Surgical Care in Sweden: A Nationwide Review of Patient Notes.

Adverse events (AEs) occur in health care and may result in harm to patients especially in the field of surgery. Our objective was to analyze AEs in surgical patient care from a nationwide perspective and to analyze the frequency of AEs that may be preventable. In total 19,141 randomly selected admissions in 63 Swedish hospitals were reviewed each month during 2013 using a 2-stage record review method based on the identification of predefined triggers. The subgroup of 3301 surgical admissions was analyzed. All AEs were categorized according to site, type, level of severity, and degree of preventability. We reviewed 3301 patients' records and 507 (15.4%) were associated with AEs. A total of 62.5% of the AEs were considered probably preventable, over half contributed to prolonged hospital care or readmission, and 4.7% to permanent harm or death. Healthcare acquired infections composed of more than one third of AEs. The majority of the most serious AEs composed of healthcare acquired infections and surgical or other invasive AEs. The incidence of AEs was 13% in patients 18 to 64 years old and 17% in ≥65 years. Pressure sores and drug-related AEs were more common in patients being ≥65 years. Urinary retention and pressure sores showed the highest degree of preventability. Patients with probably preventable AEs had in median 7.1 days longer hospital stay. We conclude that AEs are common in surgical care and the majority are probably preventable.

Direct health care costs and length of hospital stay related to health care-acquired infections in adult patients based on point prevalence measurements.

BACKGROUND: The incidence of health care-acquired infection (HAI) and the consequence for patients with HAI tend to vary from study to study. By including all patients, all medical specialties, and performing a follow-up analysis, this study contributes to previous findings in this research field. METHODS: Data from the Swedish National Point Prevalence Surveys of HAI 2010-2012 was merged with cost per patient data from the county Health Care Register (N = 6,823). Extended length of stay (LOS) and costs related to an HAI were adjusted for sex, age, intensive care unit use, and surgery. RESULTS: Patients with HAI (n = 732) had a larger proportion of readmissions compared with patients with no HAI (29.0% vs 16.5%). Of the total bed days, 9.3% was considered to be excess days attributed to the group of patients with an HAI. The excess LOS comprised 11.4% of the total costs (95% CI, 10.2-12.7). The 1-year overall mortality rate for patients with HAI in comparison to all other patients was 1.75 (95% CI, 1.45-2.11), all 5 of these differences were statistically significant (P < .001). CONCLUSIONS: Even if not all outcomes for patients with an HAI can be explained by the HAI itself, the increase in inpatient days, readmissions, associated costs, and higher mortality rates are quite notable.

[Safer Swedish healthcare requires coherent and persistent efforts]. / Säkrare svensk sjukvård kräver sammanhållet och uthålligt arbete.

Despite a development in Swedish patient safety work in recent years, unambiguous results are missing. Here we propose some activities that will result in improved patient safety. Patients and employees are a strong driving force, and should be given a more important role. The level of education in patient safety must be raised in all levels in the system. Effective systems for learning, sharing and follow-up need to be reinforced. The understanding on how the health-care system adapts to varying circumstances, resilience, needs development. The knowledge basis of what constitutes and creates safety in psychiatry, paediatric care, primary care, and in care of the elderly must be developed.

Patient safety subcultures among registered nurses and nurse assistants in Swedish hospital care: a qualitative study.

BACKGROUND: Patient safety culture emerges from the shared assumptions, values and norms of members of a health care organization, unit, team or other group with regard to practices that directly or indirectly influence patient safety. It has been argued that organizational culture is an amalgamation of many cultures, and that subcultures should be studied to develop a deeper understanding of an organization's culture. The aim of this study was to explore subcultures among registered nurses and nurse assistants in Sweden in terms of their assumptions, values and norms with regard to practices associated with patient safety. METHODS: The study employed an exploratory design using a qualitative method, and was conducted at two hospitals in southeast Sweden. Seven focus group interviews and two individual interviews were conducted with registered nurses and seven focus group interviews and one individual interview were conducted with nurse assistants. Manifest content analysis was used for the analysis. RESULTS: Seven patient safety culture domains (i.e. categories of assumptions, values and norms) that included practices associated with patient safety were found: responsibility, competence, cooperation, communication, work environment, management and routines. The domains corresponded with three system levels: individual, interpersonal and organizational levels. The seven domains consisted of 16 subcategories that expressed different aspects of the registered nurses and assistants nurses' patient safety culture. Half of these subcategories were shared. CONCLUSIONS: Registered nurses and nurse assistants in Sweden differ considerably with regard to patient safety subcultures. The results imply that, in order to improve patient safety culture, efforts must be tailored to both registered nurses' and nurse assistants' patient safety-related assumptions, values and norms. Such efforts must also take into account different system levels. The results of the present study could be useful to facilitate discussions about patient safety within and between different professional groups.

Characterisations of adverse events detected in a university hospital: a 4-year study using the Global Trigger Tool method.

OBJECTIVES: To describe the level, preventability and categories of adverse events (AEs) identified by medical record review using the Global Trigger Tool (GTT). To estimate when the AE occurred in the course of the hospital stay and to compare voluntary AE reporting with medical record reviewing. DESIGN: Two-stage retrospective record review. SETTING: 650-bed university hospital. PARTICIPANTS: 20 randomly selected medical records were reviewed every month from 2009 to 2012. PRIMARY AND SECONDARY OUTCOME MEASURES: AE/1000 patient-days. Proportion of AEs found by GTT found also in the voluntary reporting system. AE categorisation. Description of when during hospital stay AEs occur. RESULTS: A total of 271 AEs were detected in the 960 medical records reviewed, corresponding to 33.2 AEs/1000 patient-days or 20.5% of the patients. Of the AEs, 6.3% were reported in the voluntary AE reporting system. Hospital-acquired infections were the most common AE category. The AEs occurred and were detected during the hospital stay in 65.5% of cases; the rest occurred or were detected within 30 days before or after the hospital stay. The AE usually occurred early during the hospital stay, and the hospital stay was 5 days longer on average for patients with an AE. CONCLUSIONS: Record reviewing identified AEs to a much larger extent than voluntary AE reporting. Healthcare organisations should consider using a portfolio of tools to gain a comprehensive picture of AEs. Substantial costs could be saved if AEs were prevented.

Factors influencing patient safety in Sweden: perceptions of patient safety officers in the county councils.

BACKGROUND: National, regional and local activities to improve patient safety in Sweden have increased over the last decade. There are high ambitions for improved patient safety in Sweden. This study surveyed health care professionals who held key positions in their county council's patient safety work to investigate their perceptions of the conditions for this work, factors they believe have been most important in reaching the current level of patient safety and factors they believe would be most important for achieving improved patient safety in the future. METHODS: The study population consisted of 218 health care professionals holding strategic positions in patient safety work in Swedish county councils. Using a questionnaire, the following topics were analysed in this study: profession/occupation; number of years involved in a designated task on patient safety issues; knowledge/overview of the county council's patient safety work; ability to influence this work; conditions for this work; and the importance of various factors for current and future levels of patient safety. RESULTS: The response rate to the questionnaire was 79%. The conditions that had the highest number of responses in complete agreement were "patients' involvement is important for patient safety" and "patient safety work has good support from the county council's management". Factors that were considered most important for achieving the current level of patient safety were root cause and risk analyses, incident reporting and the Swedish Patient Safety Law. An organizational culture that encourages reporting and avoids blame was considered most important for improved patient safety in the future, closely followed by improved communication between health care practitioners and patients. CONCLUSION: Health care professionals with important positions in the Swedish county councils' patient safety work believe that conditions for this work are somewhat constrained. They attribute the current levels of patient safety to a broad range of factors and believe that many different solutions can contribute to enhanced patient safety in the future, suggesting that this work must be multifactorial.

What can we learn from patient claims? - A retrospective analysis of incidence and patterns of adverse events after orthopaedic procedures in Sweden.

BACKGROUND: Objective data on the incidence and pattern of adverse events after orthopaedic surgical procedures remain scarce, secondary to the reluctance for encompassing reporting of surgical complications. The aim of this study was to analyze the nature of adverse events after orthopaedic surgery reported to a national database for patient claims in Sweden. METHODS: In this retrospective review data from two Swedish national databases during a 4-year period were analyzed. We used the "County Councils' Mutual Insurance Company", a national no-fault insurance system for patient claims, and the "National Patient Register at the National Board of Health and Welfare". RESULTS: A total of 6,029 patient claims filed after orthopaedic surgery were assessed during the study period. Of those, 3,336 (55%) were determined to be adverse events, which received financial compensation. Hospital-acquired infections and sepsis were the most common causes of adverse events (n = 741; 22%). The surgical procedure that caused the highest rate of adverse events was "decompression of spinal cord and nerve roots" (code ABC**), with 168 adverse events of 17,507 hospitals discharges (1%). One in five (36 of 168; 21.4%) injured patient was seriously disabled or died. CONCLUSIONS: We conclude that patients undergoing spinal surgery run the highest risk of being severely injured and that these patients also experienced a high degree of serious disability. The most common adverse event was related to hospital acquired infections. Claims data obtained in a no-fault system have a high potential for identifying adverse events and learning from them.
