Compensation Claims After Hip Fracture Surgery in Norway 2008-2018.

Background: Surgical complications contribute to the significant mortality following hip fractures in the elderly. The purpose of this study was to increase our knowledge of surgical complications by evaluating compensation claims following hip fracture surgery in Norway. Further, we investigated whether the size and location of performing institutions would influence surgical complications. Methods: We collected data from the Norwegian System of Patient Injury Compensation (NPE) and the Norwegian Hip Fracture Register (NHFR) from 2008 to 2018. We classified institutions into 4 categories based on annual procedure volume and geographical location. Results: 90,601 hip fractures were registered in NHFR. NPE received 616 (.7%) claims. Of these, 221 (36%) were accepted, which accounts for .2% of all hip fractures. Men had nearly a doubled risk of ending with a compensation claim compared to women (OR: 1.8, CI, 1.4-2.4, P < .001). Hospital-acquired infection was the most frequent reason for accepted claims (27%). However, claims were rejected if patients had underlying conditions predisposing to infection. Institutions treating fewer than 152 hip fractures (first quartile) annually, had a statistically significant increased risk (OR: 1.9, CI, 1.3-2.8, P = .005) for accepted claims compared to higher volume facilities. Discussion: The fewer registered claims in our study could be due to the relatively high early mortality and frailty in this patient group, which may decrease the likelihood of filing a complaint. Men could have undetected underlying predisposing conditions that lead to increased risk of complications. Hospital-acquired infection may be the most significant complication following hip fracture surgery in Norway. Lastly, the number of procedures performed annually in an institution influences compensation claims. Conclusions: Our findings indicate that hospital acquired infections need greater focus following hip fracture surgery, especially in men. Lower volume hospitals may be a risk factor.

Characteristics of Patients Who Complete Suicide and Suicide Attempts While Undergoing Treatment in Norway: Findings from Compensation Claims Records.

The aim of this study was to identify characteristics that differentiate patients who complete suicide (SC) from patients with suicide attempts (SA) while undergoing treatment in Norway. We examined data from the Norwegian System of Patient Injury Compensation (Norsk Pasientskade Erstatning-NPE). Data were extracted from NPE case records from a 10-year period (2009-2019) for 356 individuals who attempted (n = 78) or died by (n = 278) suicide. The two groups differed significantly in the types of medical errors identified by experts. Inadequate suicide risk assessment tended to be proportionally and significantly more prevalent among SC compared to SA. There was a weak but significant trend that SA had received medication only, whereas SC had received both medication and psychotherapy. There were no significant differences with respect to age group, gender, diagnostic category, number of previous suicide attempts, inpatient/outpatient status, or category of responsible clinic. We conclude that suicide attempters and suicide completers differed in terms of identified medical errors. Focusing on the prevention of these and other types of errors could help to reduce the number of suicides of patients in treatment.

Patients Who Die by Suicide: A Study of Treatment Patterns and Patient Safety Incidents in Norway.

Underlying patterns and factors behind suicides of patients in treatment are still unclear and there is a pressing need for more studies to address this knowledge gap. We analysed 278 cases of suicide reported to The Norwegian System of Patient Injury Compensation, drawing on anonymised data, i.e., age group, gender, diagnostic category, type of treatment provided, inpatient vs. outpatient status, type of treatment facility, and expert assessments of medical errors. The data originated from compensation claim forms, expert assessments, and medical records. Chi-square tests for independence, multinominal logistic regression, and Bayes factors for independence were used to analyse whether the age group, gender, diagnostic category, inpatient/outpatient status, type of institution, and type of treatment received by patients that had died by suicide were associated with different types of medical errors. Patients who received medication tended to be proportionally more exposed to an insufficient level of observation. Those who received medication and psychotherapy tended to be proportionally more exposed to inadequate treatment, including inadequate medication. Inpatients were more likely to be exposed to inappropriate diagnostics and inadequate treatment and follow up while outpatients to insufficient level of observation and inadequate suicide risk assessment. We conclude that the patients who had received medication as their main treatment tended to have been insufficiently observed, while patients who had received psychotherapy and medication tended to have been provided insufficient treatment, including inadequate medication. These observations may be used as learning points for the suicide prevention of patients in treatment in Norwegian psychiatric services.

Ureteric injuries during hysterectomy-A Norwegian retrospective study of occurrence and claims for compensation over an 11-year period.

INTRODUCTION: Ureteric injury is a rare but serious, iatrogenic complication of hysterectomy. The risk depends on indication for surgery, predisposing risk factors, and peroperative conditions. Our aims were to evaluate and learn from compensation claims to The Norwegian System of Patient Injury Compensation (NPE) for ureteric injury occurring during hysterectomies to predict risk factors, time of identification, symptoms, and consequences, and to relate these cases to injuries registered in The Norwegian Patient Registry. MATERIAL AND METHODS: A retrospective study of ureteric injuries occurring during hysterectomies, reported to NPE and the Norwegian Patient Registry from 2009 through 2019. RESULTS: During the study period, 53 096 hysterectomies were registered in The Norwegian Patient Registry, of which ureteric injury was documented in 643 (1.2%). More ureteric injuries were registered in large hospital trusts than in small trusts (1.3% vs. 0.7%, p < 0.05). NPE received 69 claims due to ureteric injury occurring during hysterectomy, comprising 11% of all injuries in the study period. Compensation was approved for 15%. Women who claimed compensation were younger (48.1 ± 8.9 years vs. 55.1 ± 13.6 years, p < 0.01), more likely to have had a benign diagnosis (89.9% vs. 52.1%, p < 0.01), and more likely to have had the ureteric injury recognized after discharge (58.0% vs. 33.0%, p < 0.001) compared with non-complainants. Identification of the ureters during the hysterectomy was documented in 30% of the NPE patient files. Additional information for the NPE cases included the following. The most common symptoms of unidentified injury were pain (77%), fever (12%), urinary leakage (13%), and anuria (8%). Re-operation was necessary in 77% of the cases, and 10% of the women lost one kidney. Long-term consequences after repair, such as loss of a kidney or persistent pain, were seen in 17%. No women died because of the injury. CONCLUSIONS: The incidence of ureteric injury occurring during hysterectomy in Norway was 1.2%; 11% involved a claim for compensation, and 15% of these had their case approved. Most ureteric injuries were not recognized during the hysterectomy. Documentation of peroperative identification of the ureters during hysterectomy was often missing. Vigilance to pain as a postoperative symptom of peroperative unrecognized ureteric injury may result in earlier diagnosis and treatment.

Compensation claims in pediatric orthopedics in Norway between 2012 and 2018: a nationwide study of 487 patients.

Background and purpose - In Norway all compensation claims based on healthcare services are handled by a government agency (NPE, Norsk Pasientskade Erstatning). We provide an epidemiological overview of claims within pediatric orthopedics in Norway, and identify the most common reasons for claims and compensations.Patients and methods - All compensation claims handled by NPE from 2012 to 2018 within pediatric orthopedics (age 0 to 17 years) were reviewed. Data were analyzed with regard to patient demographics, diagnoses, type of injury, type of treatment, reasons for granted compensation, and total payouts.Results - 487 compensation claims (259 girls, 228 boys) within orthopedic surgery in patients younger than 18 years at time of treatment were identified. Mean age was 12 years (0-17). 150 out of 487 claims (31%) resulted in compensation, including 79 compensations for inadequate treatment, 58 for inadequate diagnostics, 12 for infections, and 1 based on the exceptional rule. Total payouts were US$8.45 million. The most common primary diagnoses were: upper extremity injuries (26%), lower extremity injuries (24%), congenital malformations and deformities (12%), spine deformities (11%), disorders affecting peripheral joints (9%), chondropathies (6%), and others (12%).Interpretation - Most claims were submitted and granted for mismanagement of fractures in the upper and lower extremity, and mismanagement of congenital malformations and disorders of peripheral joints. Knowledge of the details of malpractice claims should be implemented in educational programs and assist pediatric orthopedic surgeons to develop guidelines in order to improve patient safety and quality of care.

Compensation claims after hip arthroplasty surgery in Norway 2008-2018.

Background and purpose - Orthopedic surgery is one of the specialties with most compensation claims, therefore we assessed the most common reasons for complaints following total hip arthroplasty (THA) reported to the Norwegian System of Patient Injury Compensation (NPE) and viewed these complaints in light of the data from the Norwegian Arthroplasty Register (NAR).Patients and methods - We collected data from NPE and NAR for the study period (2008-2018), including age, sex, and type of complaint, and reason for accepted claims from NPE, and the number of arthroplasty surgeries from NAR. The institutions were grouped by quartiles into quarters according to annual procedure volume, and the effect of hospital procedure volume on the risk for accepted claim was estimated.Results - 70,327 THAs were reported to NAR. NPE handled 1,350 claims, corresponding to 1.9% of all reported THAs. 595 (44%) claims were accepted, representing 0.8% of all THAs. Hospital-acquired infection was the most common reason for accepted claims (34%), followed by wrong implant position in 11% of patients. Low annual volume institutions (less than 93 THAs per year) had a statistically significant 1.6 times higher proportion of accepted claims compared with higher volume institutions.Interpretation - The 0.8% risk of accepted claims following THAs is 1.6 times higher for patients treated in low-volume institutions, which should consider increasing the volume of THAs or referring these patients to higher volume institutions.

Compensation claims after knee arthroplasty surgery in Norway 2008-2018.

Background and purpose - Orthopedic surgery is one of the specialties with most compensation claims. We assessed the claims following knee arthroplasty surgery reported to the Norwegian System of Patient Injury Compensation (NPE) in light of institutional procedure volume.Patients and methods - We collected data from NPE and the Norwegian Arthroplasty Register (NAR) for the study period (2008-2018). Age, sex, type of claim, and reason for compensation were collected from NPE, while the number of arthroplasty surgeries was collected from NAR. The treating hospitals were grouped by quartiles according to annual procedure volume. The effect of hospital volume on the likelihood of an accepted claim was estimated.Results - NAR received 64,241 reports of arthroplasty procedures, of which 572 (0.9%) patients filed a claim for treatment injury. 55% of the claims were accepted, representing 0.5% of all knee arthroplasties. The most common reason for accepted claim was a hospital-acquired infection, in 28% of the patients, followed by misplaced implant (26%) and aseptic loosening (13%). The hospitals with the lowest annual volume (57 or fewer arthroplasties per year, first quarter) had a statistically significantly larger fraction of granted claims per procedures compared with other institutions.Interpretation - The overall risk of ending up with compensation due to treatment error following knee arthroplasty was 0.5%. The risk of accepted claim was greater for patients operated in the lowest volume hospitals.

Patient-reported 'treatment injuries' after hand surgery. A review of 1321 claims submitted to the Norwegian system of patient injury compensation 2007-2017.

OBJECTIVE: Hand surgery makes up a large proportion of procedures, ranging from simple to complex. Increased complexity places greater demand on hand surgery competence. Furthermore, when surgical expertise is not matched to the procedure complexity, treatment injuries might occur. The purpose of this study was to assess patient-reported claims submitted to The Norwegian System of Patient Injury Compensation (NPE). METHODS: We examined all hand surgery claims submitted to NPE between 1 January 2007 and 30 June 2017. NPE records patient demography and variables, such as diagnosis, type of injury, injury location, the reason for the compensation claim, and whether a claim was accepted or rejected. RESULTS: NPE received 1321 claims related to treatment injuries from hand surgery at a steady rate throughout the study period. A total of 532 claims were accepted (40.3%). The approval rate for trauma cases was significantly higher than for elective cases (45.5 vs. 34.2%, p < .05). The most common diagnoses were hand fractures, dislocations and ligament injuries, carpal tunnel syndrome and arthrosis of the first carpometacarpal joint. Tendon injuries had the highest percentage of accepted claims (52.6%). The most common reason for claims being accepted was 'failure of treatment'. 19.7% of these involved a disability percentage >15%. Elective surgery accounted for ⅔ of the approved disability cases. CONCLUSIONS/INTERPRETATION: This is the first national study of patient-reported injuries after hand surgery treatment in Norway. The proportion of accepted claims is similar to that seen for orthopaedics. Acceptance levels were, however, higher for hand trauma cases than for disorders treated electively. ABBREVIATIONS: NPE: Norwegian system of patient injury compensation; SD: standard deviation; CT: computed tomography; MRI: magnetic resonance imaging; UiT: University of Tromsø - Arctic University of Norway.

Correlation between compensated patient claims and 30-day mortality.

OBJECTIVE: To test if compensation claims from patients (reported to the Norwegian System of Patient Injury Compensation) are correlated with the existing quality indicator of 30-day mortality (based on data from Norwegian Patient Registry). This correlation has not been previously evaluated. DESIGN: The association between patient claims and 30-day mortality at hospital trust level was assessed by the Pearson correlation coefficient. SETTING: The Norwegian System of Patient Injury Compensation is a governmental agency under the Ministry of Health and Care Services and deals with patient-reported complaints about incorrect treatment in the public and private healthcare services. Patient-reported claims may be an indicator of healthcare quality, as 30-day mortality. PARTICIPANTS: All 19 Norwegian hospital trusts. INTERVENTIONS: : None. MAIN OUTCOME MEASURE: Patient claims rates, 30-day mortality and Pearson correlation coefficient. RESULTS: Both number of deaths within 30 days and number of claims have declined over time. High correlation (0.77, P < 0.001) was found between number of deaths within 30 days and the total number of claims. In addition, an even stronger association was found with approved claims, with a correlation coefficient of 0.83 (P < 0.001). Moreover, adjusted 30-day mortality was significantly correlated with the patient-claim rate using number of bed-days as denominator, but not when using number of discharges. CONCLUSIONS: The results from the present study indicate an association between compensation claims from patients and 30-day mortality, suggesting that both parameters reflect the latent quality of care for the hospital trusts, but they may capture different aspects of care.

Patient injuries reported to the Norwegian System of Patient Injury Compensation 2011­17. / Pasientskader hos fastleger meldt til Norsk pasientskadeerstatning 2011­17.

BACKGROUND: The Norwegian System of Patient Injury Compensation (NPE) processes compensation claims from patients who believe that they have sustained injuries during treatment in the health services. The number of cases reported to NPE has tended to increase in recent years. The purpose of this study was to obtain an overview of patient-reported injuries within the regular GP scheme. MATERIAL AND METHOD: We studied all injuries to patients within the regular GP scheme in NPE in the years 2011-17. The cases of injury contained information on age, sex, diagnosis, location of the injury and compensation paid, as well as texts describing the treatment and injury. RESULTS: Out of a total of 33 748 compensation claims submitted to NPE, 3 135 cases originated from the regular GP scheme. Of the group of claimants 53 % were women, and the average age was 44.7 years (standard deviation 17.7 years). Altogether 760 (24 %) of the cases were upheld. Diagnostic error was the reason for 553 (73 %) of the cases being upheld. The groups most frequently represented were 'tumours and cancers' (847 (27 %) of the claims) and 'orthopaedics' (592 (19 %) of the claims). INTERPRETATION: The regular GP scheme accounts for many patient contacts, and a review of patient injuries may make it possible to prevent future failures.

Performance measures among non-immigrants and immigrants attending BreastScreen Norway: a population-based screening programme.

OBJECTIVES: To explore performance measures among non-immigrants and immigrants attending BreastScreen Norway. METHODS: We analysed data from 2,951,375 screening examinations among non-immigrants and 153,026 among immigrants from 1996 to 2015. Immigrants were categorised into high- and low-incidence countries according to the incidence of breast cancer in their birth country. Performance measures, including attendance and recall rates, rates of screen-detected cancer (SDC) and interval breast cancer (IBC), positive predictive value (PPV) and histopathological tumour characteristics, were analysed. We used Fisher's exact model and t tests for descriptive statistics, and Poisson regression, adjusting for age and screening history, comparing results for non-immigrants versus immigrants. RESULTS: Attendance rates were 78% for non-immigrants and 56% for immigrants (p < 0.001). Rates of prevalent screens were 24% for non-immigrants and 32% for immigrants (p < 0.001). Immigrants from low-incidence countries were younger at diagnosis than non-immigrants (57 years versus 60 years, p < 0.001). Recall rates were 3.1% for non-immigrants and 3.8% for immigrants (p < 0.001), while PPVs were 17% and 14% (p < 0.001), respectively. IBCs in immigrants from low-incidence countries were more often triple negative (RRadj 1.81, 95% CI 1.11-2.94) than those in non-immigrants. Both SDC and IBC in immigrants from low-incidence countries tended more often to be histological grade 3 than those in non-immigrants. CONCLUSION: Immigrants had lower attendance rates, higher recall rates and lower PPV than non-immigrants. The optimal age range and screening interval for immigrant women from low-incidence countries need to be further investigated. KEY POINTS: • Immigrants from countries with a low incidence of breast cancer had their breast cancer diagnosed at a younger age than non-immigrants. • Interval breast cancers detected in immigrants from countries with a low incidence of breast cancers were more often triple negative than those in non-immigrants. • The optimal age range and screening interval for immigrant women from low-incidence countries and non-immigrants might differ.

Pathology-related cases in the Norwegian System of Patient Injury Compensation in the period 2010-2015. / Patologirelaterte saker i pasientskadeordningen i perioden 2010 ­ 15.

BACKGROUND: The Norwegian System of Patient Injury Compensation (NPE) processes compensation claims from patients who complain about malpractice in the health services. A wrong diagnosis in pathology may cause serious injury to the patient, but the incidence of compensation claims is unknown, because pathology is not specified as a separate category in NPE's statistics. Knowledge about errors is required to assess quality-enhancing measures. We have therefore searched through the NPE records to identify cases whose background stems from errors committed in pathology departments and laboratories. MATERIAL AND METHOD: We have searched through the NPE records for cases related to pathology for the years 2010 ­ 2015. RESULTS: During this period the NPE processed a total of 26 600 cases, of which 93 were related to pathology. The compensation claim was upheld in 66 cases, resulting in total compensation payments amounting to NOK 63 million. False-negative results in the form of undetected diagnoses were the most frequent grounds for compensation claims (63 cases), with an undetected malignant melanoma (n = 23) or atypia in cell samples from the cervix uteri (n = 16) as the major groups. Sixteen cases involved non-diagnostic issues such as mix-up of samples (n = 8), contamination of samples (n = 4) or delayed responses (n = 4). INTERPRETATION: The number of compensation claims caused by errors in pathology diagnostics is low in relative terms. The errors may, however, be of a serious nature, especially if malignant conditions are overlooked or samples mixed up.

Complaints to the Norwegian System of Patient Injury Compensation 2001-14 following nerve blockade. / Klager etter nerveblokade til Norsk pasientskadeerstatning 2001 ­ 14.

BACKGROUND: There has been a steady increase in cases reported to the Norwegian System of Patient Injury Compensation (NPE). We wished to look into what might characterise those cases of central and peripheral nerve blockade for anaesthesia that led to compensation claims. MATERIAL AND METHOD: Cases with codes for central and peripheral blockade within the field of anaesthesiology were retrieved from the NPE database for the period 2001 ­ 14. The cases were evaluated on the basis of variables including sex, age, type of anaesthesia, diagnosis, type of injury, site of injury, damages received, and written descriptions of treatment and injury. The expert reports were anonymised and reviewed in detail. RESULTS: A total of 339 patient compensation claims relating to nerve blockade were identified, of which 149 concerned spinal anaesthesia, 142 epidural anaesthesia, 21 combined spinal and epidural anaesthesia and 27 peripheral nerve blockade. The group consisted of 236 women and 103 men, and the average age was 46 years. The 339 cases comprised 0.8 % of all cases reported to the NPE in this period. A total of 107 claims resulted in compensation. Eighty-two million Norwegian kroner were paid out in total. INTERPRETATION: Peripheral and central nerve blockade accounts for only a small proportion of cases handled by the NPE. Only one in three applicants had their claim upheld, but when claims were upheld, the injuries were often severe and led to substantial pay-outs.

GFRA3 promoter methylation may be associated with decreased postoperative survival in gastric cancer.

BACKGROUND: A large number of epigenetic alterations has been found to be implicated in the etiology of gastric cancer. We have studied the DNA methylation status of 27 500 gene promoter regions in 24 gastric adenocarcinomas from a Norwegian cohort, and aimed at identifying the hypermethylated regions. We have compared our findings to the gene expression in the same tissue, and linked our results to prognosis and survival. METHODS: Biopsies from gastric adenocarcinomas and adjacent normal gastric mucosa were obtained from 24 patients following surgical resection of the tumor. Genome-wide DNA methylation profiling of the tumor and matched non-cancerous mucosa was performed. The results were compared to whole transcriptome cDNA microarray analysis of the same material. RESULTS: Most of the gene promoter regions in both types of tissue showed a low degree of methylation, however there was a small, but significant hypermethylation of the tumors. Hierarchical clustering showed separate grouping of the tumor and normal tissue. Hypermethylation of the promoter region of the GFRA3 gene showed a strong correlation to post-operative survival and several of the clinicopathological parameters, however no difference was found between the two main histological types of gastric cancer. There was only a modest correlation between the DNA methylation status and gene expression. CONCLUSIONS: The different DNA methylation clusters of the tumors and normal tissue indicate that aberrant DNA methylation is a distinct feature of gastric cancer, although there is little difference in the overall, and low, methylation levels between the two tissue types. The GFRA3 promoter region showed marked hypermethylation in almost all tumors, and its correlation with survival and other clinicopathological parameters may have important prognostic significance.

Processes of enhanced self-understanding during a counselling programme for parents of children with disabilities.

BACKGROUND: The stress and burden on parents of children with disabilities are well documented, and the parents' way of handling the situation is crucial to the health and well-being of all family members, including the child with special needs. We conducted a group-based counselling programme for parents, based mainly on Gestalt education and personal construct theories, aiming at increasing the parents' ability to handle the situation. AIMS: To explore the parents' experiences from processes of change after the counselling programme. METHOD DESIGN: This qualitative study is based on modified grounded theory. METHOD: The study conducted in Norway examines the experiences of 67 parents (of whom 29 fathers) of children with disabilities. Information was collected through focus group discussions after finishing their sessions of the counselling programme. FINDINGS: From the parents' experiences, the following categories were developed: feeling motivated to communicate, describing oneself in new words, being inspired to experience one's own emotions, being more present and in charge and making a difference by taking new steps. The core category in our analysis turned out to be Improved handling of the situation by enhanced self-understanding. The parents seemed to redevelop their self-understanding through new experiences of themselves. They emphasized the importance of a secure setting of peers with similar experiences and skilled counsellors to feel free to explore one's own emotions with connecting thoughts and bodily reactions. Discussion of existential issues as one's own values also contributed to enhanced self-understanding, which strengthened the parents to find new possibilities and priorities in handling the situation. CONCLUSIONS: The parents described subjective processes of awareness and self-reflection as important for being able to start a process towards enhanced self-understanding, which helped to detect one's own values and new ways of acting. These experiences may be relevant for the parents and for the conduction of future counselling.

The endothelin axis in the metastatic process of colon carcinoma.

BACKGROUND: The endothelin axis has recently emerged as an important factor in tumour metastasis. The aim of this study was to investigate the endothelin axis and its downstream pathways related to metastasis in colon carcinoma. MATERIALS AND METHODS: mRNA expression of 36 genes associated with the endothelin axis in 18 non-metastatic and 20 metastatic colon carcinomas with individual-matched normal mucosa were evaluated using real-time reverse transcription polymerase chain reaction. RESULTS: Seventeen out of 36 genes, including endothelin A receptor, were significantly overexpressed in the tumour tissue compared to the individual-matched normal mucosa. Seven out of 36 genes, including endothelin B receptor, were significantly down-regulated in tumour tissue. Phosphatase and tensin homolog (PTEN) was significantly down-regulated in the metastatic patients compared to the non-metastatic patients. CONCLUSION: This study indicated that central genes in the endothelin axis are overexpressed when colon tissue becomes malignant. Down-regulation of PTEN may promote a progressive phenotype of colon carcinomas.
