The assessment of patient reported outcomes and health-related quality of life continue to be rapidly evolving areas of research and this new edition reflects the development within the field from an emerging subject to one that is an essential part of the assessment of clinical trials and other clinical studies.

Rehospitalization is common after sepsis, but little is known about the variation in readmission patterns across patient groups and care locations. To examine the variation in postsepsis readmission rates and diagnoses by patient age, nursing facility use, admission year, and hospital among U.S. Veterans Affairs (VA) beneficiaries. Observational cohort study of VA beneficiaries who survived a sepsis hospitalization (2009-2011) at 114 VA hospitals, stratified by age (<65 vs. ≥65 yr), nursing home usage (none, chronic, or acute), year of admission (2009, 2010, 2011), and hospital. In the primary analysis, sepsis hospitalizations were identified using a previously validated method. Sensitivity analyses were performed using alternative definitions with explicit International Classification of Diseases, Ninth Revision, Clinical Modification, codes for sepsis, and separately for severe sepsis and septic shock. The primary outcomes were rate of 90-day all-cause hospital readmission after sepsis hospitalization and proportion of readmissions resulting from specific diagnoses, including the proportion of \"potentially preventable\" readmissions. Readmission diagnoses were similar from 2009 to 2011, with little variation in readmission rates across hospitals. The top six readmission diagnoses (heart failure, pneumonia, sepsis, urinary tract infection, acute renal failure, and chronic obstructive pulmonary disease) accounted for 30% of all readmissions. Although about one in five readmissions had a principal diagnosis for infection, 58% of all readmissions received early systemic antibiotics. Infection accounted for a greater proportion of readmissions among patients discharged to nursing facilities compared with patients discharged to home (25.0-27.1% vs. 16.8%) and among older vs. younger patients (22.2% vs. 15.8%). Potentially preventable readmissions accounted for a quarter of readmissions overall and were more common among older patients and patients discharged to nursing facilities. Hospital readmission rates after sepsis were similar by site and admission year. Heart failure, pneumonia, sepsis, and urinary tract infection were common readmission diagnoses across all patient groups. Readmission for infection and potentially preventable diagnoses were more common in older patients and patients discharged to nursing facilities.

There is a paucity of data regarding the optimal surgical approach for lung lobectomy. Lobectomy performed by video-assisted thoracoscopic surgery (VATS) has been associated with lower morbidity as compared with lobectomy performed by thoracotomy. However, no multicenter studies have shown improved mortality with VATS lobectomy compared with open surgical lobectomy. We used data from the United States Healthcare Cost and Utilization Project Nationwide Inpatient Sample database from 2009 to 2012 to compare VATS with open lobectomy for in-hospital mortality and other short-term outcomes. We used International Classification of Diseases, Ninth Revision, Clinical Modification procedure codes to identify the patients undergoing lobectomy. We used 1:1 ratio propensity matching with the nearest neighbor method without replacement to generate matched pairs. Over the 4-year period, 27,451 patients underwent lobectomy. The majority of these procedures were performed by thoracotomy (65%) as compared with VATS (35%). A total of 9,393 matched pairs were created. VATS lobectomy was associated with significantly lower in-hospital mortality when compared with thoracotomy (1.3% vs. 2.5%, P < 0.001). A shorter length of hospital stay was observed for those undergoing VATS lobectomy (6.21 vs. 8.75 d, P < 0.001). The overall rate of perioperative complications was low, with those undergoing VATS being less likely to have any perioperative morbidity. In recent years, the use of VATS for lobectomy has increased relative to thoracotomy. This trend has coincided with increased survival and shorter length of stay for VATS lobectomy compared with thoracotomy. Further studies are needed to identify comorbidities that identify ideal candidates for VATS lobectomy.

Sepsis is a leading cause of death and disability whose heterogeneity is often cited as a key impediment to translational progress. To test the hypothesis that there are consequential and significant differences in sepsis outcomes that result from differences in a patient's clinical course leading up to sepsis hospitalization. We conducted an observational cohort study of U.S. Health and Retirement Study (HRS) participants in Medicare (1998-2012) and U.S. Department of Veterans Affairs beneficiaries (2009). Using latent profile analysis, we identified patient subtypes based on trajectory of presepsis healthcare facility use. Subtypes were identified in the derivation cohort (1,512 sepsis hospitalizations among earlier HRS participants), then validated them in two additional cohorts (1,992 sepsis hospitalizations among later HRS participants; 32,525 sepsis hospitalizations among U.S. Department of Veterans Affairs beneficiaries). We measured the association between presepsis path and 90-day mortality using chi-square tests and multivariable logistic regression. We identified three subtypes: low use of inpatient healthcare facilities, comprising 84% of the derivation cohort; rising use, 12%; and high use, 4%. The shape and distribution of presepsis trajectories were similar in all three cohorts. In the derivation cohort, 90-day mortality differed by presepsis trajectory as follows: 38% (low use), 63% (rising use), and 48% (high use) (P < 0.001). This association persisted in the validation cohorts (P < 0.001 for each). The rising use class remained an independent predictor of mortality after adjustment for potential confounders, including detailed physiologic data. In national cohorts of patients with sepsis, we have shown that several distinct paths into sepsis exist. These paths, identified by trajectories of presepsis healthcare use, are predictive of 90-day mortality.

Background We do not yet know whether or the extent to which multimodal therapy changes the health behaviors and health service use of chronic headache patients in the long term. Associations are expected between pain symptoms and pain management abilities for patients who are categorized as successfully treated and those who remain unchanged. Methods Routine longitudinal data of an enrolment period of five years from 101 headache patients treated with a two-week, full-day, semi-inpatient multimodal pain therapy at the Interdisciplinary Pain Center of the University Clinic Erlangen were available when therapy began and 12 months after treatment. To investigate long-term changes in health behavior and health service use as well as their associations with the outcome “reduction in pain days,” we used descriptive and inferential statistics (i.e., binary logistic regression). Results Patients who underwent interdisciplinary treatment showed statistically significant changes in their health behavior in five areas. Twelve months after treatment, we found a significantly higher frequency of engagement in athletic sports ( p  < .001) as well as increases in the use of relaxation techniques ( p  < .001), TENS devices for relaxation purposes ( p  = .008), psychological coping strategies ( p  < .001), and mindfulness-based techniques for dealing with pain ( p  < .001). 52.8% of the sample reported a reduction in the number of pain days 12 months after treatment. Binary logistic regression (χ 2 (12) = 21.419; p  = .045; R 2  = .255) revealed that a reduction in pain days 12 months after treatment was positively associated with regular physical activity in the form of muscle strengthening and stretching (athletic sports) ( p  = .012). Conclusion Chronic headache patients acquired long-term skills from an interdisciplinary treatment concerning the use of relaxation techniques, the use of psychological coping strategies, and physical activity in the form of athletic exercise. Of those, regular athletic exercise was positively associated with a smaller number of pain days in the long term. Thus, a physical activity module should be an element of interdisciplinary treatment for chronic headache patients.

Background After traumatic brain injury (TBI), hypotension, hypoxia and hypercapnia have been shown to result in secondary brain injury that can lead to increased mortality and disability. Effective prehospital assessment and treatment by emergency medical service (EMS) is considered essential for favourable outcome. The aim of this study was to evaluate the effect of a physician-staffed helicopter emergency medical service (HEMS) in the treatment of TBI patients. Methods This was a retrospective cohort study. Prehospital data from two periods were collected: before (EMS group) and after (HEMS group) the implementation of a physician-staffed HEMS. Unconscious prehospital patients due to severe TBI were included in the study. Unconsciousness was defined as a Glasgow coma scale (GCS) score ≤ 8 and was documented either on-scene, during transportation or by an on-call neurosurgeon on hospital admission. Modified Glasgow Outcome Score (GOS) was used for assessment of six-month neurological outcome and good neurological outcome was defined as GOS 4–5. Results Data from 181 patients in the EMS group and 85 patients in the HEMS group were available for neurological outcome analyses. The baseline characteristics and the first recorded vital signs of the two cohorts were similar. Good neurological outcome was more frequent in the HEMS group; 42% of the HEMS managed patients and 28% ( p  = 0.022) of the EMS managed patients had a good neurological recovery. The airway was more frequently secured in the HEMS group ( p  < 0.001). On arrival at the emergency department, the patients in the HEMS group were less often hypoxic ( p  = 0.024). In univariate analysis HEMS period, lower age and secured airway were associated with good neurological outcome. Conclusion The introduction of a physician-staffed HEMS unit resulted in decreased incidence of prehospital hypoxia and increased the number of secured airways. This may have contributed to the observed improved neurological outcome during the HEMS period. Trial registration ClinicalTrials.gov IDNCT02659046. Registered January 15th, 2016.

Background Over the past decade, the importance of person-centered care has led to increased interest in patient-reported outcome measures (PROMs). In cardiovascular care, selecting an appropriate PROM for clinical use or research is challenging because multimorbidity is often common in patients. The aim was therefore to provide an overview of heart-disease specific PROMs and to compare the content of those outcomes using a bio-psycho-social framework of health. Methods A scoping review of heart disease-specific PROMs, including arrhythmia/atrial fibrillation, congenital heart disease, heart failure, ischemic heart disease, and valve diseases was conducted in PubMed (January 2018). All items contained in the disease-specific PROMs were mapped to WHO’s International Classification of Functioning, Disability and Health (ICF) according to standardized linking rules. Results A total of 34 PROMs (heart diseases in general n  = 5; cardiac arrhythmia n  = 6; heart failure n  = 14; ischemic heart disease n  = 9) and 147 ICF categories were identified. ICF categories covered Body functions ( n  = 61), Activities & Participation ( n  = 69), and Environmental factors ( n  = 17). Most items were about experienced problems of Body functions and less often about patients’ daily activities, and most PROMs were specifically developed for heart failure and no PROM were identified for valve disease or congenital heart disease. Conclusions Our results motivate and provide information to develop comprehensive PROMs that consider activity and participation by patients with various types of heart disease.

Ataxia management is mainly based on rehabilitation, symptomatic management, and functional improvement. Therefore, it is important to comprehensively assess ataxic symptoms and their impact on function. Recently, the movement disorders society recommended four generic ataxia rating scales: scale for assessment and rating of ataxia (SARA), international cooperative ataxia rating scales, Friedreich’s ataxia rating scale (FARS), and unified multiple system atrophy rating scale (UMSARS). The aim of the study was to analyze and compare the content of the recommended ataxia rating scales by linking them to the international classification of functioning, disability and health (ICF). A total of 125 meaningful concepts from 93 items of the four included scales were linked to 57 different ICF categories. The ICF categories were distributed in body structure (n = 8), body function (n = 26), activity and participation (n = 20), and environmental factors (n = 3) components. UMSARS and FARS were the only ones that have addressed the body structure or environmental factors component. The content analysis of ataxia rating scales would help clinicians and researchers select the most appropriate scale and understand ataxic symptoms and their impact on function. It seems that SARA is the optimal scale for rapid assessment of ataxia or in busy clinical settings. UMSARS or FARS are more appropriate for the investigating the impact of ataxia on overall health, and monitoring ataxia progression and disability.

Objective: To determine the effect of Cochlear Implants on electrophysiological and behavioural response in children with hearing impairment at frequencies of 500, 1000, 2000, and 4000 Hz. Study Design: Cross sectional study. Place and Duration of Study: Department of ENT, Combined Military Hospital Rawalpindi Pakistan, from Jul 2021 to Jul 2022. Methodology: Seventy children with hearing impairment aged 2-12 years of either gender, who had undergone cochlear implantation were part of the study. Language and hearing conditions were examined during the audiological assessment of candidates for cochlear implantation. At ER-tone 5A and TDH-39 using ISO 389-2 and 389-1 calibrations, warble tones given at different frequencies were used to derive behavioral air conduction thresholds. The Auditory Steady State Response test began with a carrier frequency of 500 Hz and advanced to frequencies of 1000, 2000, and 4000 Hz. Thresholds were set using a 10 dB down and 5 dB up procedure until no responses could be captured. Behavioral and Auditory Steady State Response responses were noted in all patients. Results: Mean age of the patients was 6.66±2.74 years. Behavioral threshold>110 dB HL were obtained in 8(11.4%) subjects, 10(14.3%) had behavioral thresholds from 100 to 110 dB HL, and 52(74.3%) had <100 dB HL. Eleven patients obtained Auditory Steady State Response thresholds>110 dB HL (15.7%), 31(44%) achieved 100 to 110 dB HL and 28(40%) achieved <100 dB HL. The most common frequency was 500 Hz. Statistically insignificant difference was found between  ... Conclusion: Cochlear implantation has positive effect on behavioral and ...

Background A core outcome set (COS) is an agreed standardised collection of outcomes that should be measured and reported by all trials for a specific clinical area, in this case chronic rhinosinusitis. These are not restrictive and researchers may continue to explore other outcomes alongside these that they feel are relevant to their intervention. The aim of this systematic review was to identify the need for a COS for chronic rhinosinusitis. Methods A sensitive search strategy was used to identify all published Cochrane systematic reviews and randomised control trials of intervention for adult patients with chronic rhinosinusitis. Two independent authors reviewed these to obtain a list of outcomes and outcome measures reported by each clinical trial. Results Sixty-nine randomised control trials and eight Cochrane systematic reviews were included in this study. They reported 68 individual outcomes and outcome measures, with an average of four to ten outcomes per clinical trial. These outcomes were mapped to 23 subcategories belonging to eight core categories. Conclusions The key finding of this review was the heterogeneity of outcomes reported and measured by clinical trials of patients with chronic rhinosinusitis, precluding meaningful meta-analysis of data. This review supports the need for development of a COS, to be used in future trials on adult patients with chronic rhinosinusitis.
