Most patients with an increased risk for sepsis-related morbidity or death do not recognize sepsis as a medical emergency: results of a survey study using case vignettes.

BACKGROUND: Sepsis is a medical emergency with potentially life-threatening consequences. Patients play a crucial role in preventing and recognizing sepsis at an early stage. The understanding of risk groups' sepsis knowledge and their ability to use this knowledge to recognize sepsis as an emergency is incomplete. METHODS: We conducted a cross-sectional survey in Germany and included a sample of 740 persons stratified by age (< 60 years, ≥ 60 years), specific chronic diseases (e.g. diabetes, chronic diseases, cancer), and region (Berlin/Brandenburg vs. other federal states of Germany). Standardized questionnaires were administered by a market research institute through online, telephone, or face-to-face methods. We assessed sepsis knowledge through a series of questions and the ability to recognize sepsis as an emergency through five case vignettes. To identify predictors of sepsis knowledge and the ability to recognize sepsis as a medical emergency, we conducted multiple linear regressions. RESULTS: Of the 36 items on sepsis knowledge, participants answered less than 50 per cent correctly (mean 44.1%; standard deviation (SD) 20.1). Most patients knew that sepsis is a defensive host response to infection (75.9%), but only 30.8% knew that vaccination can prevent infections that lead to sepsis. Across the five vignettes, participants identified sepsis as an emergency in only 1.33 of all cases on average (SD = 1.27). Sepsis knowledge was higher among participants who were older, female, and more highly educated and who reported more extensive health information seeking behaviour. The ability to recognize sepsis as an emergency was higher among younger participants, participants without chronic diseases, and participants with higher health literacy, but it was not significantly associated with sepsis knowledge. CONCLUSIONS: Risk groups showed low levels of knowledge regarding the preventive importance of vaccination and a low ability to recognize sepsis as a medical emergency. Higher levels of sepsis knowledge alone were not sufficient to improve the ability to identify sepsis as a medical emergency. It is crucial to develop effective educational strategies-especially for persons with lower education levels and infrequent health information seeking behaviour-that not only transfer but also facilitate the choice of appropriate actions, such as seeking timely emergency care.

Interprofessional collaboration and patient-reported outcomes: a secondary data analysis based on large scale survey data.

BACKGROUND: While interprofessional collaboration (IPC) is widely considered a key element of comprehensive patient treatment, evidence focusing on its impact on patient-reported outcomes (PROs) is inconclusive. The aim of this study was to investigate the association between employee-rated IPC and PROs in a clinical inpatient setting. METHODS: We conducted a secondary data analysis of the entire patient and employee reported data collected by the Picker Institute Germany in cross-sectional surveys between 2003 and 2016. Individual patient data from departments within hospitals was matched with employee survey data from within 2 years of treatment at the department-level. Items assessing employee-rated IPC (independent variables) were included in Principal Component Analysis (PCA). All questions assessing PROs (overall satisfaction, less discomforts, complications, treatment success, willingness to recommend) served as main dependent variables in ordered logistic regression analyses. Results were adjusted for multiple hypothesis testing as well as patients' and employees' gender, age, and education. RESULTS: The data set resulted in 6154 patients from 19 hospitals respective 103 unique departments. The PCA revealed three principal components (department-specific IPC, interprofessional organization, and overall IPC), explaining 67% of the total variance. The KMO measure of sampling adequacy was .830 and Bartlett's test of sphericity highly significant (p < 0.001). An increase of 1 SD in department-specific IPC was associated with a statistically significant chance of a higher (i.e., better) PRO-rating about complications after discharge (OR 1.07, 95% CI 1.00-1.13, p = 0.029). However, no further associations were found. Exploratory analyses revealed positive coefficients of department-specific IPC on all PROs for patients which were treated in surgical or internal medicine departments, whereas results were ambiguous for pediatric patients. CONCLUSIONS: The association between department-level IPC and patient-level PROs remains - as documented in previous literature - unclear and results are of marginal effect sizes. Future studies should keep in mind the different types of IPC, their specific characteristics and possible effect mechanisms.

Does the second opinion directive in Germany reach the patient? A parallel-convergent mixed-methods study.

BACKGROUND: A Second Opinion Directive (SOD) was introduced in Germany in December 2018 for elective surgeries such as hysterectomy, tonsillotomy, tonsillectomy, and shoulder arthroscopy. The aim of the SOD is to avoid surgeries which are not medically induced and to support patients in their decision-making process. A physician who indicates an SOD-relevant procedure must inform the patient about the SOD and its specifications. At this time, it is not clear whether physicians provide information about the SOD to patients and whether and how the SOD is implemented in daily practice. Furthermore, nothing is known about how patients react when they are told that they have the right to seek a second opinion according to the SOD. METHODS: To assess this, we undertook a parallel-convergent mixed-methods study with a qualitative and quantitative phase. Qualitative data were analysed by structured qualitative content analysis and survey data were analysed descriptively. RESULTS: 26 interviews were conducted with patients for whom one of the above-mentioned surgeries was indicated. In parallel, a questionnaire survey with 102 patients was conducted. The results show that the SOD is not implemented in Germany for the selected indications because patients were not informed as intended. At the same time, when the right to obtain a second opinion was explained, it seemed to have a positive effect on the physician-patient relationship from patients` perspective. CONCLUSIONS: It is possible that there is a lack of information for physicians, which in turn leads to an information deficit for patients. Better information for physicians might be part of the solution, but a negative attitude towards the SOD might also result in the low education rate. Therefore, in addition, potential patients or even the general population should be better informed about the possibility of obtaining a second opinion.

[Recommendations for a Core Curriculum for Master's Degree Programs in Health Services Research]. / Empfehlungen für ein Kerncurriculum für Masterstudiengänge der Versorgungsforschung.

The aim of the present study was to develop recommendations for a core curriculum for master's degree programs in health services research. For this purpose, a standardized online survey of university lecturers was conducted in the first step. In the second step, the curricula of the existing study programs were analyzed. In the third step, a literature search was conducted. In the last step, the resulting recommendations were discussed in a panel of experts. The final recommendations comprise 13 topics on five guiding questions with 26 subtopics. The main topics come from the areas of basic sciences in the context of health services research, the health care system and health policy, the (empirical) health services research process, and knowledge transfer. The present recommendations will serve as a basis for discussion and as a starting point. The development of recommendations should be seen as an ongoing process, as the core competencies of health services researchers will have to be continuously adapted to new research topics, new research methods and regulations.

Second opinion opportunity declined: patient typology and experiences regarding the decision-making process preceding elective surgeries in Germany.

BACKGROUND: To address the problem of overuse of elective surgery and to support patients in their decision-making process, a Second Opinion Directive was introduced in Germany, which enables patients with statutory health insurance to obtain a second opinion for certain surgical indications. The study aims to identify, based on the experiences of patients who have undergone elective surgery, the role of seeking a second opinion in reaching their decision. METHODS: Sixty-two patients who had undergone an elective surgery (hysterectomy, tonsillectomy, shoulder arthroscopy) were recruited using purposive sampling and interviewed during October to December 2020. The transcribed interviews were analysed using a framework analysis to create a typology from the patient's perspective. RESULTS: The time spent by patients in making the decision to undergo surgery varies between individuals, and is influenced by factors such as the type of physician-patient relationship, individual patient aspects, prior experiences in the health care system, as well as information needs. Within the framework of the analysis, we were able to identify three patterns of patient types based on the three different time-points or phases when decisions were typically made, with one type being divided into two subtypes: Type 1a: Quick decision making, Type 1b: Overwhelmed quick decision making, Type 2: Time to consider, Type 3: Struggling with the decision. CONCLUSIONS: Patients who followed a recommendation for elective surgery appreciate having the possibility to seek a second opinion. However, various factors influenced their opting for a second opinion during the decision-making process. Patients have differing information needs, such that a one-size-fits-all second opinion service may not fit adequately for all patients.

[Educational Programmes in Health Services Research in Germany: Current State and Future Perspectives]. / Studiengänge zur Versorgungsforschung in Deutschland: aktueller Stand und zukünftige Perspektiven.

OBJECTIVE: The aim of this study was to analyse accredited study programmes of health services research in Germany at Master's degree level regarding their structural data and content. METHODS: Using a descriptive qualitative design, all included plans of study courses, module handbooks and descriptions of the Master's degree programmes were analysed. RESULTS: The Master's degree programmes were similar in their structural elements as well as in their content of education. They aim at enhancing competences related to the areas of health services research to identify health care needs and to develop, initiate, evaluate and critically assess innovative care strategies across disciplines. DISCUSSION: Although the content is similar, the study programmes focus on specific aspects that allow students to choose a certain programme depending on their preferences. A next step can be the development of a core curriculum that takes into consideration further findings and the discourse of different stakeholders.

[Necessity and Ways to Develop Care Goals for the Health System in Germany - a Position Paper of the DNVF]. / Notwendigkeit und Wege zur Entwicklung von Versorgungszielen für das Gesundheitssystem in Deutschland ­ ein Positionspapier des DNVF.

Goals for health and health care are an indispensable basic requirement for a functioning health care system. The dilemma of the German health care system is that it has not been designed in a planned way, but that it has grown historically. In recent years, it has developed through the free play of forces into what it is today. The OECD characterizes the current state as follows: The costs of the German health system do not correspond to the often only average health outcomes for the population. To meet the legal requirements (especially SGB V §§ 12, 27 and 70), health care/the health system in Germany needs concrete goals. An orientation towards health care goals entails measures on all levels of health care: on the macro level (overall system/total population), on the meso level (subdivided according to regions, specific population groups, etc.) as well as on the micro level (patients and health care providers). Based on national and international experiences, this position paper of the DNVF e.V. (German Network for health services research) shows the potential of how operationalised health care targets can ensure effective, affordable and high-quality health care. The coalition agreement of the current government propagates a reorientation with patient-related health care goals. Now it is important to derive concrete and realisable goals from this declaration of intent and to involve all important groups in the process. In addition, values and ethical standards for implementation shall be agreed upon in this process. The Health Ministry (BMG) should facilitate and promote the process of societal will-building for the definition of national health care goals. This requires a clear political will. As a result, the National Health Care Goals are available at the end of the process, which are published and maintained together with evidence-based facts as well as valid and resilient data in a Manual "National Health Care Goals". The operational responsibility for implementation could lie with the newly to be founded Federal Institute of Public Health, as already announced in the agreement of the governing coalition. The DNVF is willing to actively participate in the development of health care targets.

Contextualising the association of socioeconomic deprivation with hospitalisation rates of myocardial infarction in a rural area in eastern Germany.

INTRODUCTION: Evidence on the association of socioeconomic deprivation with occurrence of acute myocardial infarction (AMI) is available from international studies and urban settings in western Germany. This study aimed to assess this association based on small geographical areas in a rural setting in eastern Germany. METHODS: This study used routine data of all patients with AMI who were treated in the Hospital Brandenburg in the city of Brandenburg, Germany, between May 2019 and May 2020. Hospitalisation rates of AMI were calculated for postal code regions that were located within the catchment area of the Hospital Brandenburg. Poisson regression was used to compare hospitalisation rates in areas with medium socioeconomic deprivation to areas with high deprivation, controlling for age group, sex and period (before or during COVID-19 pandemic). Publicly available social, infrastructure and healthcare-related features were mapped to characterise the study region. RESULTS: In total, 265 cases of AMI were registered in the study area, which comprised 116,126 inhabitants. The city of Brandenburg was characterised by the highest level of socioeconomic deprivation, while neighbouring areas showed a rural settlement structure and medium levels of deprivation. The number of general practitioners per 10 000 inhabitants did not differ between both areas. The adjusted rate ratio comparing hospitalisations due to AMI in areas with medium socioeconomic deprivation to areas with high socioeconomic deprivation was 0.71 (95%CI 0.56-0.91, p=0.01). CONCLUSION: This study adds evidence about the association of socioeconomic deprivation and AMI occurrence from a rural area in eastern Germany. Further research about the relationship of socioeconomic deprivation and cardiovascular health is needed from heterogeneous contexts.

Synthetic Versus Biological Mesh in Laparoscopic and Open Ventral Hernia Repair (LAPSIS): Results of a Multinational, Randomized, Controlled, and Double-blind Trial.

OBJECTIVE: The aim of this study was to investigate the approach (open or laparoscopic) and mesh type (synthetic or biological) in ventral hernias in a clean setting.Summary of Background Data: The level of evidence on the optimal surgical approach and type of mesh in ventral hernia repair is still low. METHODS: Patients with a ventral abdominal hernia (diameter 4-10 cm) were included in this double-blind randomized controlled trial across 17 hospitals in 10 European countries. According to a 2 × 2-factorial design, patients were allocated to 4 arms (open retromuscular or laparoscopic intraperitoneal, with synthetic or Surgisis Gold biological mesh). Patients and outcome assessors were blinded to mesh type used. Major postoperative complication rate (hernia recurrence, mesh infection, or reoperation) within 3 years after surgery, was the primary endpoint in the intention-to-treat population. RESULTS: Between September 1st, 2005, and August 7th, 2009, 253 patients were randomized and 13 excluded. Six of 61 patients (9.8%) in the open synthetic mesh arm, 15 of 66 patients (22.7%) in the open biological mesh arm, 7 of 64 patients (10.9%) in the laparoscopic synthetic mesh arm and 17 of 62 patients (27.4%) in the laparoscopic biological mesh arm had a major complication. The use of biological mesh resulted in significantly more complications (P = 0.013), also after adjusting for hernia type, body mass index, and study site. The trial was prematurely stopped due to an unacceptable high recurrence rate in the biological mesh arms. CONCLUSIONS: The use of Surgisis Gold biological mesh is not recommended for noncomplex ventral hernia repair. TRIAL REGISTRATION: This trial was registered at controlled-trials.com (ISRCTN34532248).

A systematic review and time-response meta-analysis of the optimal timing of elective caesarean sections for best maternal and neonatal health outcomes.

BACKGROUND: The rate of caesarean sections (CS) has increased in the last decades to about 30% of births in high income countries. Many CSs are electively planned without an urgent medical reason for mother or child. An early CS though may harm the newborn. Our aim was to evaluate the gestational time point after the 37 + 0 week of gestation (WG) (after prematurity = term) of performing an elective CS with the lowest morbidity for mother and child by assessing the time course from 37 + 0 to 42+ 6 WG. METHODS: We performed a systematic literature search in MEDLINE, EMBASE, CENTRAL and CINAHL in November 2018. We included studies that compared different time points of elective CS at term no matter the reason for elective CS. Our primary outcomes were the rate of admissions to the neonatal intensive care unit (NICU), neonatal death and maternal death in early versus late term elective CS. Various binary and dose response random effects meta-analyses were performed. RESULTS: We identified 35 studies including 982,749 women. Except one randomised controlled trial, all studies were cohort studies. We performed a linear time-response meta-analysis on the primary outcome NICU admission on 14 studies resulting in a decrease of the relative risk (RR) to 0.63 (95% CI 0.56, 0.71) from 37 + 0 to 39 + 6 WG. RR for neonatal death showed a decrease to 39 + (0-6) WG (RR 0.59 95% CI 0.43 to 0.83) and increase from then on (RR 2.09 95% CI 1.18 to 3.70) assuming a U-shape course and using a cubic spline model for meta-analysis of four studies. We only identified one study analyzing maternal death resulting in RR of 0.38 (95% CI 0.04 to 3.40) for 37 + 0 + 38 + 6 WG versus ≥39 + 0 WG. CONCLUSION: Our systematic review showed that elective CS (primary and repeated) before the 39 + 0 WG lead to more NICU admissions and neonatal deaths, although death is rare and increases again after 39 + 6 WG. We did not find enough evidence on maternal outcomes. There is a need for more research, considering maternal outcomes to provide a balanced decision between neonatal and maternal health. SYSTEMATIC REVIEW REGISTRATION: Registered in PROSPERO (CRD42017078231).

Results of a patient-oriented second opinion program in Germany shows a high discrepancy between initial therapy recommendation and second opinion.

BACKGROUND: As of 2015, second opinions are legally implemented in Germany. However, empirical results from German second opinion programs are lacking. The aim of this study was to examine several aspects within a population of a German second opinion program. METHODS: Study population consisted of patients who sought a second opinion in the period from August 2011 to December 2016. Multivariate logistic regression and ANOVA were used to examine differences in patient characteristics, differentiated by agreement of initial therapy recommendation and second opinion. Follow-up points for patient satisfaction and HRQoL were defined at 1, 3 and 6 months after obtaining the second opinion. RESULTS: Total number of patients who sought a second opinion was 1414. Most common indications concerned the knee (37.3%), spine (27.3%), hip (11.5%) and shoulder (10.1%). The independent specialists did not confirm the initial therapy recommendations in two out of three cases. The type of indication influenced the agreement between initial therapy recommendation and the second opinion significantly (p = 0.035). The second opinion and the offered service was highly valued by the patients (89%). CONCLUSIONS: The second opinion offers patients the possibility to confirm a medical indication independently and support patients in their decision making process. Reasons for the large discrepancy between initial therapy recommendation and second opinion should be addressed in future research.

Interesting different survival status of musicians with malignant cerebral tumors.

Introduction: The education of a musician may have an effect on the neuronal functions and organization of the brain, promote brain plasticity, resulting in functional and structural changes. A variety of malign cerebral tumors have affected the musician, instrumentalist or singer, at some time during their lives. No comprehensive investigation for musicians with malignant tumors has been performed yet. The aims of the study are to investigate if there is a relationship between the performed music style (classic or pop/rock) and the malignancy of the tumor.Patients and methods: The key words were 'neurosurgery and music' and the names of composers. We used digital catalogs like 'Pubmed' as well as the libraries of universities. We investigated a list of people with brain tumors from the English Wikipedia. (https://en.wikipedia.org/wiki/List_of_people_with_brain_tumors).We divided musicians into two groups according to their performing of classic or rock-pop music, and their gender.Results: We found 27 classic and rock/pop musicians who suffered from malign cerebral tumors. The median survival time estimations were 18 (mean 22.33, 95% CI ranged from 7.49 to 37.17) months for pop-rock musicians and 8 (mean 8.67, 95% CI ranged from 4.13 to 12.19) months for classical music performers. However, in Cox regression analysis, performed classical music type was associated with an increased risk of early death, lesser survival time age associated with an adjusted hazard ratio (aHR) of 1.06 [95% confidence interval (CI) 1.020 to 1.111; p = .004),Conclusion: In musicians with malign cerebral tumors, music type performed by musician may affect the survival status, classical musicians have a worse outcome than rock-pop musicians.

[Pilot Project: Reinforcement of Outpatient Palliative Care in the State of Brandenburg - An Analysis of Documentation Data of Primary Palliative Care]. / Pilotprojekt zur Stärkung der ambulanten Palliativversorgung im Land Brandenburg ­ Analyse von Dokumentationsdaten der allgemeinen ambulanten Palliativversorgung.

BACKGROUND: Quantitative data on primary palliative care (AAPV) in Germany is scarce. In order to reinforce outpatient palliative care, a pilot project was implemented and evaluated in 2 regions of Brandenburg. The aim of this study was to gain an insight into AAPV based on documentation data from the pilot project: How was AAPV realized in the pilot project? How does the implementation of AAPV differ in the 2 project regions? MATERIALS AND METHODS: The study is based on retrospective analysis of the data on 108 patients documented by 13 physicians in 2 regions of Brandenburg using PalliDoc® software. The results were analysed by descriptive statistical methods. RESULTS: Each participating doctor documented the care process of 7.7 patients on average during the observation period. Overall, about 66% of the patients were diagnosed with a tumour as the main diagnosis. The average duration of care for patients in the pilot project was 171.3 days. On average, doctors documented 9.1 contacts per patient with contacts lasting 20:28 min. The average route to the patient was 9.3 kilometres. CONCLUSIONS: Our results indicate that the execution of AAPV is highly dependent on regional circumstances as well as on the existing offers and services of hospice and palliative care. Compared to data from the evaluation of palliative care teams in other German regions, it appears that the care processes in AAPV last longer and a larger number of patients without underlying oncological disease has been treated under AAPV than in specialized palliative care.

[Memorandum Registry for Health Services Research: Update 2019]. / Memorandum Register für die Versorgungsforschung: Update 2019.

Health registries could be used to analyze questions concerning routine practice in healthcare. Therefore, registries are a core method in health services research. The German Network for Health Services Research (Deutsches Netzwerk Versorgungsforschung, DNVF) promotes the quality of registries by scientific exchange, organization of advanced training, and recommendations in the form of a memorandum "Registry for Health Services Research". The current recommendations are an update of the memorandum's first version of 2010. The update describes the capabilities and aims of registries in health services research. Furthermore, it illustrates the state-of-the-art in designing and implementing health registries. The memorandum provides developers the methodological basis to ensure high quality health registries. It further provides users of health registries with insights that enable assessing the quality of data and results of health registries. Finally, funding agencies and health policy actors can use the quality criteria to establish a framework for the financing and legislative requirements for health registries. The memorandum provides first a definition of health registries and presents an overview of their utility in health services research and health care improvement. Second, several areas of methodological importance for the development and operation of health registries are presented. This includes the conceptual and preliminary design, implementation, technical organization of a health registry, statistical analysis, reporting of results, and data protection. From these areas, criteria are deduced to allow the assessment of the quality of a health registry. Finally, a checklist is presented.

A different aspect of the unexpected death of Mozart at the age of 35 years.

The cause of the early death of Wolfgang Amadeus Mozart (1756-1791) at the age of 35 has been the source of much discussion in the medical community. Investigators attributed to Mozart nearly 150 different medical diagnoses. However, the neurosurgical aspect of the early death of Mozart has yet to be well-analyzed, and this subject was investigated herein. The key words "Mozart" and "Mozart's death" were searched in PubMed as well as the libraries of universities. The main source was the archive and website of Internationale Stiftung MOZARTEUM/Salzburg (www.mozarteum.at) and the cranium stored in the Internationale Stiftung Mozarteum in Salzburg/Austria. The linear fracture of the cranium is important, since it shows the neurosurgical aspect of the early death of Mozart. Mozart's disease was most likely a neurotraumatologic one. His fracture likely occurred several months before his death, as evidenced by signs of healing. Intense headaches and declining musical performance in his last year may have been influenced by intracranial hemorrhage induced by the linear fracture. His final disease therefore may have been chronic postconcussion syndrome depending on chronic calcified epidural hematoma.

["If they were to stop coming, I'd panic" : Palliative care networks from the perspectives of patients and informal care givers]. / "Wenn die mal nicht mehr kommen würden, dann kriege ich eine Krise" : Netzwerke der ambulanten Palliativversorgung aus Sicht von Patienten und Angehörigen.

OBJECTIVE: This study examines the perspectives of patients and family caregivers on outpatient palliative care networks. It contrasts primary palliative care (AAPV) and specialized outpatient care (SAPV) services, particularly in regard to pain management. METHODS: The study is based on 27 semi-structured, problem-focussed interviews with 21 patients and 19 informal caregivers. Recruitment was based on purposive sampling in two regions of Brandenburg, Germany. The data were analysed using qualitative content analysis. RESULTS: In AAPV, the general practitioner (GP) is both the central point of contact as well as the coordinator of the care network. In SAPV, the GP plays a less important role. This can lead to conflicts between GPs and health care professionals of the palliative care team. Compared to AAPV, palliative care teams are attributed greater intervention capacities in acute situations as well as expertise in pain therapy. Thus, the option of parenteral administration of opioids is considered a benefit of specialized care. The use of nursing services varies considerably depending on the individual care network-in some cases care is completely taken over by relatives. Relatives are the closest to the patient within the care network and perform key tasks. CONCLUSION: The personal and professional composition of networks of outpatient palliative care varies individually according to care situation and form. Care networks of AAPV and SAPV differ with regard to the accessibility of health care professionals and pain therapy. Home-based palliative care is often made possible by informal care givers in the first place.

External Validation and Update of the RICP-A Multivariate Model to Predict Chronic Postoperative Pain.

Objective: The development of chronic postsurgical pain (CPSP) is influenced by several factors. The risk index for chronic pain (RICP) was developed to identify patients at high risk for CPSP. The aim of this study was the external validation and update of the RICP. Design: Prospective cohort study. Setting: Two German hospitals. Subjects: Participants who underwent orthopedic surgery, general surgery, visceral surgery, and neurosurgery. Methods: The predicted outcome was CPSP at six months. We validated the original RICP externally and performed a model update. Analysis was performed using logistic regression. We analyzed the discrimination and calibration of the model. Furthermore, the updated model was internally validated. Results: We included 205 patients. The mean age of participants was 51 years. CPSP was reported by 53.9% of participants. In our population, the original RICP (preoperative pain in the operating field, other preoperative pain, postoperative acute pain, capacity overload, and comorbid stress symptoms) showed a sensitivity of 0.708 and a specificity of 0.727 (area under the curve [AUC] = 0.766, 95% confidence interval [CI] = 0.688-0.843). The updated RICP (preoperative pain in the operating field, other preoperative pain, postoperative acute pain, sex, marital status) yielded a sensitivity of 0.746 and a specificity of 0.726 (AUC = 0.813, 95% CI = 0.740-0.886). The results were confirmed by cross-validation. Pre- and postoperative pain measures showed the highest predictive ability. Discussion: The study indicates external validity of the original RICP. The updated RICP also showed good predictive ability. The results are limited by the small sample size and the amount of missing outcome data.

Postoperative Pain Trajectories and Pain Chronification-an Empirical Typology of Pain Patients.

Background: High intensity of acute postsurgical pain is one of the strongest predictors of chronic postsurgical pain (CPSP). We investigated if different types of patients with distinct combinations of initial pain intensity and rate of pain resolution exhibit different risks for increased pain intensity six months after surgery. Methods: Data from 174 patients were examined using growth mixture analysis by means of structural equation modeling. Results: Three types of patients were distinguished on the basis of acute pain trajectories. The majority of patients (57%) showed an unproblematic pattern of little initial pain on the first postoperative day, combined with further pain resolution over the four subsequent days. There also was a substantial group of patients (30%) who started out with severe pain but exhibited a high rate of pain resolution. Finally, we found a problematic group of patients (13%) who reported high pain intensities throughout all five postoperative measurements, with no signs of pain resolution. Even after controlling for preoperative pain intensity, these patients exhibited significantly higher pain intensities six months after surgery than the remaining patient groups. Conclusions: In this study, we demonstrated that there is substantial variation in postsurgical pain trajectories, not only with regard to postsurgical initial pain intensity, but also with regard to individual rates of pain resolution. Successful pain resolution appeared to be a better predictor of absence of increased pain intensities six months after surgery than initial pain immediately after surgery. Hence, attention should be given to appropriate pain treatment in order to minimize the risk of CPSP.
