RÉSUMÉ

With limited healthcare resources, it is important to provide the right level and form of care. The aim of this study was to determine whether selected single-jaw orthognathic surgery in outpatient care (OPC) generates lower healthcare costs than in inpatient care (IPC). The costs of surgically assisted rapid maxillary expansion (SARME), Le Fort I osteotomy (LFI), and bilateral sagittal split osteotomy (BSSO) were calculated for 165 patients, 107 treated in OPC and 58 in IPC. Additionally, costs for revisits, emergency visits, emergency phone calls, re-operations, and plate removal during the first 12 months postoperatively were recorded. The total mean costs of the different operations including revisits, emergency visits, and phone calls were 34.2-48.8% lower in OPC than in IPC at 12 months postoperatively. Operation costs were lower for LFI in OPC (P = 0.009) and for SARME in IPC (P = 0.007). Anaesthesia costs were lower for LFI (P < 0.001) and BSSO (P < 0.001) in OPC, and there were fewer revisits (P = 0.001) and lower costs (P = 0.002) after LFI in OPC compared to IPC. This study showed that selected single-jaw orthognathic surgeries in outpatient care are associated with lower healthcare costs compared to inpatient care.

RÉSUMÉ

BACKGROUND: IGF signaling has been implicated in the pathogenesis and progression of ovarian carcinoma (OC). Single agent activity and safety of ganitumab (AMG 479), a fully human monoclonal antibody against IGF1R that blocks binding of IGF1 and IGF2, were evaluated in patients with platinum-sensitive recurrent OC. METHODS: Patients with CA125 progression (GCIG criteria) or measurable disease per RECIST following primary platinum-based therapy received 18 mg/kg of ganitumab q3w. The primary endpoint was objective response rate (ORR) assessed per RECIST 1.1 by an independent radiology review committee (IRC) and/or GCIG CA125 criteria. Secondary endpoints included clinical benefit rate (CBR), progression free survival (PFS) and overall survival (OS). RESULTS: 61 pts. were accrued. Objective responses were seen in 5/61 patients (ORR 8.2%, 95% CI, 3.1-18.8) with 1 partial response (PR) by RECIST and 2 complete responses (CR) as well as 2 PR by CA125 criteria. CBR was 80.3% (95% CI, 67.8-89.0%). The median PFS according to RECIST by IRC was 2.1 months (95% CI, 2.0-3.1). The median PFS per RECIST IRC and/or CA125 was 2.0 months (95% CI, 1.8-2.2). The median OS was 21 months (95% CI, 19.5-NA). The most common overall adverse events were fatigue (36.1%) and hypertension (34.4%). Grade 1/2 hyperglycemia occurred in 30.4% of patients. Hypertension (11.5%) and hypersensitivity (8.2%) were the most frequent grade 3 adverse events. CONCLUSIONS: IGF1R inhibition with ganitumab was well-tolerated, however, our results do not support further study of ganitumab as a single agent in unselected OC patients.

RÉSUMÉ

Orthognathic surgery is traditionally performed in inpatient care. The question is whether patient safety is maintained when orthognathic surgery is performed in outpatient care. This retrospective cohort study was conducted to investigate patient safety in selected single-jaw orthognathic surgeries performed in outpatient care compared to inpatient care. Postoperative infection, postoperative bleeding, postoperative pain, plate removal, and re-operation, as well as emergency visits/phone calls and postoperative admission during the first 12 months after surgery were recorded. Predictor variables were sex, age, smoking, general disease, antibiotics, operation type, and operation time. Of the 165 patients included, 58 were treated in inpatient care and 107 in outpatient care. No significant difference was found between the groups regarding postoperative bleeding, pain, plate removal, re-operation, or emergency visits/phone calls. Ninety-four percent of outpatients (n = 101) were able to leave the hospital on the day of surgery as planned. There was an increased risk of postoperative infection in the outpatient care group (odds ratio 2.46, P = 0.049). Selected single-jaw orthognathic surgery can be performed in the outpatient setting, with maintained patient safety. The reason for the increased risk of postoperative infection among patients operated in outpatient care should be investigated in further studies.

RÉSUMÉ

Decreased physical activity (PA) has been associated with residents living in neighborhoods perceived as being disordered or having high crime levels. What is unknown are the characteristics of individuals who engage in moderate to vigorous levels of PA (MVPA) despite living in these vulnerable neighborhoods, or who may be referred to as positive deviants (PD). We examined the factors associated with PD for PA among Jamaicans. Between 2016 and 2017 the Jamaica Health and Lifestyle Survey, a cross-sectional nationally representative survey (n = 2807), was conducted on individuals aged 15 years and older. Regression analyses were performed to identify associations with PD, defined using engagement in MVPA among persons living in vulnerable neighborhoods (N = 1710). Being female (odds ratio [OR]a = 0.64 (0.48, 0.86); p = 0.003), obese while living in an urban area (ORa = 0.39; 95 % CI = 0.26, 0.59; p < 0.0001), unemployed (ORa = 0.53; 95 % CI = 0.39, 0.73; p < 0.0001), or a student (ORa = 0.62; 95 % CI = 0.39, 0.98); p = 0.041) was associated with a significantly lower likelihood of PD, while having a personal medical history of at least one chronic disease significantly increased likelihood (ORa = 1.43; 95 % CI = 1.08, 1.90; p = 0.014). Taking a PD approach may be one angle to consider in trying to determine what is working and for whom, so that this may be harnessed in policy, prevention and intervention programming to increase PA.

RÉSUMÉ

BACKGROUND: TAFRO syndrome is a rare clinical subtype of idiopathic multicentric Castlemans disease characterised by thrombocytopenia, anasarca, myelofibrosis, renal dysfunction, and organomegaly. Renal involvement is common, sometimes requiring temporary renal replacement therapy. Due to the associated thrombocytopenia, renal biopsies are rarely performed limiting descriptions of the renal histopathology in this condition. This case describes a patient with TAFRO syndrome and the associated renal histology. CASE PRESENTATION: A 49-year-old Caucasian man presented to a tertiary hospital in Sydney with a six- week history of malaise, non-bloody diarrhoea, progressive shortness of breath, and drenching night sweats. A progressive bicytopenia and renal function decline necessitating temporary dialysis prompted a bone marrow aspirate and trephine, as well as a renal biopsy respectively. This noted a hypercellular bone marrow with increased granulopoiesis, reduced erythropoiesis, and fibrosis, with renal histology suggesting a thrombotic microangiopathic-like glomerulopathy. Alternate conditions were excluded, and a diagnosis of TAFRO syndrome was made. Glucocorticoids and rituximab were initiated with rapid renal recovery, and normalisation of his haematologic parameters achieved at six months. CONCLUSION: This case describes an atypical thrombotic microangiopathy as the predominant histologic renal lesion in a patient with TAFRO syndrome. This was responsive to immunosuppression with glucocorticoids and rituximab, highlighting the importance of early recognition of this rarely described condition.

RÉSUMÉ

OBJECTIVE: COVID-19 toes represent the main dermatological COVID-19 cutaneous manifestation in pediatric patients. Its diagnosis exposes the whole family to social stigma and this aspect was not previously evaluated. PATIENTS AND METHODS: This was a multicenter, case-control, observational study that compared the family impact of COVID-19 toes vs. psoriasis (PsO). We enrolled 46 pediatric patients (23 with psoriasis and 23 with COVID-19 toes, age and gender matched) and their parents/caregivers that had to fill the Dermatitis Family Impact (DFI) questionnaire. RESULTS: DFI index did not differ significantly between both subgroups (p=0.48), and in psoriatic patients did not correlate with both Psoriasis Area Severity Index (PASI) (p=0.59) and itch-VAS (p=0.16). CONCLUSIONS: COVID-19 toes, a transitory dermatosis, exerted a similar impact/perturbation on family dynamics than PsO, a well-known stigmatizing, chronic inflammatory dermatosis.

RÉSUMÉ

PURPOSE: Insulin-like growth factor (IGF) signaling is implicated in pathogenesis and chemotherapy resistance of epithelial ovarian cancer (EOC). We explored efficacy and safety of adding ganitumab, a monoclonal antibody targeting IGF-1R, to carboplatin/paclitaxel (CP) chemotherapy in patients with primary EOC. DESIGN: Patients were randomly assigned to receive CP/ganitumab (18 mg/kg q3w) or CP/placebo for 6 cycles followed by 6 cycles of single agent ganitumab/placebo maintenance therapy as front-line therapy. Primary endpoint was progression free survival. Secondary endpoints were time to progression and overall survival. Pretreatment samples were prospectively collected for retrospective biomarker analyses. RESULTS: 170 patients enrolled. 165 patients assessable for toxicity. Median PFS was 15.7 months with CP/ganitumab and 16.7 months with CP/placebo (HR 1.23; 95% CI 0.82-1.83, P = 0.313). All grade neutropenia (84.1% vs 71.4%), thrombocytopenia (75.3% vs 57.1%) and hyperglycemia (15.9% vs 2.6%) were more common in the ganitumab group compared to the placebo group. Ganitumab/placebo related serious adverse events were reported in 26.1% of the patients with ganitumab and in 6.5% with placebo. Non-progression related fatal events were more common with ganitumab (5 versus 2 patients). The ganitumab group experienced more dose delays which resulted in lower relative dose intensity of chemotherapy in the experimental group. In an exploratory model IGFBP2 expression was predictive of ganitumab response (treatment interaction; PFS, P = 0.03; OS, P = 0.01). CONCLUSION: Addition of ganitumab to CP chemotherapy in primary EOC did not improve PFS. Our results do not support further study of ganitumab in unselected EOC patients.

RÉSUMÉ

PURPOSE: To study pain perception in 10-15-year-olds, during and after uncomplicated extractions of bilateral maxillary premolars. The study investigated pain's natural course and made comparisons between the first and second extractions. METHODS: 31 Swedish children in need of orthodontic treatment were identified and consecutively enrolled. Tooth extractions followed a standardised protocol and the two teeth were extracted with at least 10 days between. The participants rated pain intensity using visual analogue scale (VAS) at 14 different time points from treatment and 7 days forward. RESULTS: The pain intensity profile followed the same pattern for all patients. Pain intensity peaked 2 h after extractions (mean VASPI 27.3, SD 20.8; median 23.0) when moderate pain intensity (VASPI ≥ 40) was registered for 16 (28%) of 57 cases. After that, there was a rapid decrease in pain intensity notable already at 4 h after extractions. There were no statistically significant differences in any VASPI measurements between the first and second extractions, sexes, or different age groups. CONCLUSIONS: The majority of the participants who undergo uncomplicated bilateral extraction of maxillary premolars experience mild to moderate levels of postoperative pain during a short period of time, with no differences between the first and second extractions. Bilateral tooth extractions is a suitable model for further studies on pain management.

RÉSUMÉ

The breakdown of the polymeric component of contemporary composite dental restorative materials compromises their longevity, while leachable compounds from these materials have cellular consequences. Thus, a new generation of composite materials needed to be designed to have a longer service life and ensure that any leachable compounds are not harmful to appropriate cell lines. To accomplish this, we have developed concurrent thiol-ene-based polymerization and allyl sulfide-based addition-fragmentation chain transfer chemistries to afford cross-linked polymeric resins that demonstrate low shrinkage and low shrinkage stress. In the past, the filler used in dental composites mainly consisted of glass, which is biologically inert. In several of our prototype composites, we introduced fluorapatite (FA) crystals, which resemble enamel crystals and are bioactive. These novel prototype composites were benchmarked against similarly filled methacrylate-based bisphenol A diglycidyl ether dimethacrylate / triethylene glycol dimethacrylate (bisGMA/TEGDMA) composite for their cytotoxicity, mechanical properties, biofilm formation, and fluoride release. The leachables at pH 7 from all the composites were nontoxic to dental pulp stem cells. There was a trend toward an increase in total toughness of the glass-only-filled prototype composites as compared with the similarly filled bisGMA/TEGDMA composite. Other mechanical properties of the glass-only-filled prototype composites were comparable to the similarly filled bisGMA/TEGDMA composite. Incorporation of the FA reduced the mechanical properties of the prototype and bisGMA/TEGDMA composite. Biofilm mass and colony-forming units per milliliter were reduced on the glass-only-filled prototype composites as compared with the glass-only-filled bisGMA/TEGDMA composite and were significantly reduced by the addition of FA to all composites. Fluoride release at pH 7 was greatest after 24 h for the bisGMA/TEGDMA glass + FA composite as compared with the similarly filled prototypes, but overall the F- release was marginal and not at a concentration to affect bacterial metabolism.

RÉSUMÉ

Despite a substantial amount of animal data linking deficits in memory inhibition to the development of overeating and obesity, few studies have investigated the relevance of memory inhibition to uncontrolled eating in humans. Further, although memory for recent eating has been implicated as an important contributor to satiety and energy intake, the possibility that variations in episodic memory relate to individual differences in food intake control has been largely neglected. To examine these relationships, we recruited ninety-three adult subjects to attend a single lab session where we assessed body composition, dietary intake, memory performance, and eating behaviors (Three Factor Eating Questionnaire). Episodic recall and memory inhibition were assessed using a well-established measure of memory interference (Retrieval Practice Paradigm). Hierarchical regression analyses indicated that memory inhibition was largely unrelated to participants' eating behaviors; however, episodic recall was reliably predicted by restrained vs. uncontrolled eating: recall was positively associated with strategic dieting (ß = 2.45, p = 0.02), avoidance of fatty foods (ß = 3.41, p = 0.004), and cognitive restraint (ß = 1.55, p = 0.04). In contrast, recall was negatively associated with uncontrolled eating (ß = -1.15, p = 0.03) and emotional eating (ß = -2.46, p = 0.04). These findings suggest that episodic memory processing is related to uncontrolled eating in humans. The possibility that deficits in episodic memory may contribute to uncontrolled eating by disrupting memory for recent eating is discussed.

RÉSUMÉ

This health technology assessment evaluated the efficacy of pharmacological treatment in patients with oro-facial pain. Randomised controlled trials were included if they reported pharmacological treatment in patients ≥18 years with chronic (≥3 months) oro-facial pain. Patients were divided into subgroups: TMD-muscle [temporomandibular disorders (TMD) mainly associated with myalgia]; TMD-joint (TMD mainly associated with temporomandibular joint pain); and burning mouth syndrome (BMS). The primary outcome was pain intensity reduction after pharmacological treatment. The scientific quality of the evidence was rated according to GRADE. An electronic search in PubMed, Cochrane Library, and EMBASE from database inception to 1 March 2017 combined with a handsearch identified 1552 articles. After screening of abstracts, 178 articles were reviewed in full text and 57 studies met the inclusion criteria. After risk of bias assessment, 41 articles remained: 15 studies on 790 patients classified as TMD-joint, nine on 375 patients classified as TMD-muscle and 17 on 868 patients with BMS. Of these, eight studies on TMD-muscle, and five on BMS were included in separate network meta-analysis. The narrative synthesis suggests that NSAIDs as well as corticosteroid and hyaluronate injections are effective treatments for TMD-joint pain. The network meta-analysis showed that clonazepam and capsaicin reduced pain intensity in BMS, and the muscle relaxant cyclobenzaprine, for the TMD-muscle group. In conclusion, based on a limited number of studies, evidence provided with network meta-analysis showed that clonazepam and capsaicin are effective in treatment of BMS and that the muscle relaxant cyclobenzaprine has a positive treatment effect for TMD-muscle pain.

RÉSUMÉ

OBJECTIVE: A number of case reports have demonstrated FDG uptake around mesh prostheses after hernia repair surgery. This study characterizes FDG PET-CT findings after hernia repair with synthetic mesh in a series of cancer patients. MATERIALS AND METHODS: FDG PET-CT studies were reviewed for increased FDG uptake consistent with CT appearances of post-surgical hernia repair in cancer patients. The findings were correlated with clinical data and follow-up studies. RESULTS: 53 PET-CT studies in 22 patients (18 males, 31-79 years) were identified. Surgery for repair of inguinal (n = 14), ventral (n = 5) or umbilical (n = 3) hernia was performed, 4-204 months prior to PET-CT. FDG avidity was focal or linear in the region of the anterior abdominal or pelvic wall (mean SUV max 4.0 ± 2.3). Corresponding nonspecific CT findings included soft tissue thickening (n = 18), fat infiltration (n = 20) and fluid collection (n = 19) in the region of the omentum, adjacent to or in the inner abdominal or pelvic wall at the surgical site. Linear hyper-dense structures (n = 9) or metallic clips (n = 8) seen on CT suggested benign postoperative changes. In 10/12 (83.3%) patients with repeat PET-CT, FDG uptake remained unchanged, one showed more diffuse uptake and another showed reduced uptake on follow-up. There was neither significant change in CT appearance at the surgical site in these 12 patients, nor in 3 additional patients with only CT follow-up. Another 3 patients had previous CT demonstrating hernia at the same location. CONCLUSION: With increasing use of synthetic mesh, awareness of variations in FDG PET-CT appearance is important to avoid false interpretation in cancer patients.

RÉSUMÉ

BACKGROUND: Damage biomarkers may identify mechanisms and sites of acute kidney injury (AKI). However, the utility of novel AKI biomarkers differs by context, and their utility for monitoring treatment of AKI is unknown. We hypothesized that selected AKI biomarkers would facilitate monitoring of mechanism-specific treatment. We examined this using a panel of biomarkers to monitor cisplatin-induced AKI treatment with alpha-lipoic acid (α-LA) that has previously been demonstrated to ameliorate cisplatin induced AKI. METHODS: AKI was induced in male Sprague Dawley rats using cisplatin (6mg/kg) in the presence or absence of a single dose of α-LA (100mg/kg). A panel of 12 urinary kidney damage biomarkers (CystatinC, NGAL albumin, alpha-1-acid glycoprotein, clusterin, KIM-1, osteopontin, total protein, cytochrome C, epidermal growth factor, interleukin-18 and malondialdehyde was examined as well as histological injury, serum creatinine and cystatin C, and clinical parameters. RESULTS: Cisplatin treatment modified all parameters, except interleukin-18 and malondialdehyde, with each parameter demonstrating a different temporal profile. α-LA treatment attenuated renal tubular injury scores (P <0.05), decreased peak serum creatinine (p=0.004) and cystatin C (p=0.04), and urinary damage biomarkers of proximal tubular injury (CystatinC, NGAL, albumin, and alpha-1-acid glycoprotein). Other urinary biomarkers were not modified. Neither α-LA alone, nor the cisplatin vehicle (DMSO) modified biomarker profiles. CONCLUSIONS: α-LA treatment ameliorated cisplatin-induced AKI. Protection was demonstrated by reduced structural damage, improved glomerular filtration and reduced excretion of urinary biomarkers of proximal tubular damage. Effective treatment of AKI can be monitored by site and perhaps by mechanism-specific kidney damage biomarkers.

RÉSUMÉ

BACKGROUND: Childhood adversity predicts adolescent suicidal ideation but there are few studies examining whether the risk of childhood adversity extends to suicidal ideation in midlife. We hypothesized that childhood adversity predicts midlife suicidal ideation and this is partially mediated by adolescent internalizing disorders, externalizing disorders and adult exposure to life events and interpersonal difficulties. METHOD: At 45 years, 9377 women and men from the UK 1958 British Birth Cohort Study participated in a clinical survey. Childhood adversity was prospectively assessed at the ages of 7, 11 and 16 years. Suicidal ideation at midlife was assessed by the depressive ideas subscale of the Revised Clinical Interview Schedule. Internalizing and externalizing disorders were measured by the Rutter scales at 16 years. Life events, periods of unemployment, partnership separations and alcohol dependence were measured through adulthood. RESULTS: Illness in the household, paternal absence, institutional care, parental divorce and retrospective reports of parental physical and sexual abuse predicted suicidal ideation at 45 years. Three or more childhood adversities were associated with suicidal ideation at 45 years [odds ratio (OR) 4.31, 95% confidence interval (CI) 2.67-6.94]. Psychological distress at 16 years partially mediated the associations of physical abuse (OR 3.41, 95% CI 2.29-5.75), sexual abuse (OR 4.99, 95% CI 2.90-11.16) with suicidal ideation. Adult life events partially mediated the association of parental divorce (OR 6.34, 95% CI -7.16 to 36.75) and physical (OR 9.59, 95% CI 4.97-27.88) and sexual abuse (OR 6.59, 95% CI 2.40-38.36) with suicidal ideation at 45 years. CONCLUSIONS: Adversity in childhood predicts suicidal ideation in midlife, partially mediated by adolescent internalizing and externalizing disorders, adult life events and interpersonal difficulties. Understanding the pathways from adversity to suicidal ideation can inform suicide prevention and the targeting of preventive interventions.

RÉSUMÉ

BACKGROUND: Public participation in scientific data collection is a rapidly expanding field. In water quality surveys, the involvement of the public, usually as trained volunteers, generally includes the identification of aquatic invertebrates to a broad taxonomic level. However, quality assurance is often not addressed and remains a key concern for the acceptance of publicly-generated water quality data. The Open Air Laboratories (OPAL) Water Survey, launched in May 2010, aimed to encourage interest and participation in water science by developing a 'low-barrier-to-entry' water quality survey. During 2010, over 3000 participant-selected lakes and ponds were surveyed making this the largest public participation lake and pond survey undertaken to date in the UK. But the OPAL approach of using untrained volunteers and largely anonymous data submission exacerbates quality control concerns. A number of approaches were used in order to address data quality issues including: sensitivity analysis to determine differences due to operator, sampling effort and duration; direct comparisons of identification between participants and experienced scientists; the use of a self-assessment identification quiz; the use of multiple participant surveys to assess data variability at single sites over short periods of time; comparison of survey techniques with other measurement variables and with other metrics generally considered more accurate. These quality control approaches were then used to screen the OPAL Water Survey data to generate a more robust dataset. RESULTS: The OPAL Water Survey results provide a regional and national assessment of water quality as well as a first national picture of water clarity (as suspended solids concentrations). Less than 10 % of lakes and ponds surveyed were 'poor' quality while 26.8 % were in the highest water quality band. CONCLUSIONS: It is likely that there will always be a question mark over untrained volunteer generated data simply because quality assurance is uncertain, regardless of any post hoc data analyses. Quality control at all stages, from survey design, identification tests, data submission and interpretation can all increase confidence such that useful data can be generated by public participants.

RÉSUMÉ

AIMS: We aimed to determine the effectiveness of CK19 mRNA copy number and tumour related factors in predicting non-sentinel axillary nodal involvement, in order to facilitate the formulation of local treatment guidelines for axillary clearance (ANC) following intra-operative analysis of the sentinel node biopsy (SNB) using one-step nucleic acid amplification (OSNA). METHODS: Patients due to have (SNB) at our institution for breast cancer as well as patients with high grade ductal carcinoma in situ with pre-operative negative assessment of the axilla were included. Alternate slices of each node were sent for assessment by either OSNA or histopathology. Immediate ANC was performed if OSNA was positive. The CK19 mRNA nodal copy number, the total tumour load (TTL) measured by summation of mRNA copy numbers of all positive nodes, the nodal status at ANC and tumour characteristics for each patient were recorded. A model of risk probability was constructed using TTL and tumour related factors. RESULTS: 664 nodes were analysed from 425 patients who had SNB performed between 2011 and 2014. ANC was performed on 105 of these patients. The concordance between OSNA and histology was 91.4% and negative predictive value (NPV) was 97%. TTL (p = 0.003) and LVI (p = 0.04) were identified as risk factors for non-sentinel nodal involvement. The risk probability model identified all patients with pN2 disease for ANC. CONCLUSION: In the future a decision to perform ANC will be based on a risk stratification model based on TTL and tumour related factors.

RÉSUMÉ

OBJECTIVE: As prostate-specific antigen (psa) makes prostate cancer (pca) screening more accessible, more men are being identified with conditions that indicate high risk for developing pca, such as elevated psa and high-grade intraepithelial neoplasia (hgpin). In the present study, we assessed psychological well-being and risk perception in individuals with those high-risk conditions. METHODS: A questionnaire consisting of a psychological symptom survey, a trait risk-aversion survey, and a cancer-specific risk perception survey was administered to 168 patients with early-stage localized pca and 69 patients at high risk for pca (n = 16 hgpin, n = 53 psa > 4 ng/mL). Analysis of variance was used to examine differences in psychological well-being and appraisal of risk between the groups. RESULTS: Compared with the pca group, the high-risk group perceived their risk of dying from something other than pca to be significantly lower (p = 0.007). However, pca patients reported significantly more clinically important psychological symptoms. CONCLUSIONS: The identification of prostate conditions that predict progression to cancer might not result in the psychological symptoms commonly experienced by pca patients, but does appear to be related to a distorted perception of the disease's mortal risk. Patients with pca experience reduced psychological well-being, but better understand the risks of pca recurrence and death. Education on the risks and outcomes of pca can help at-risk men to view health assessments with reduced worry.

RÉSUMÉ

OBJECTIVES: Dental care for elderly nursing home residents is traditionally provided at fixed dental clinics, but domiciliary dental care is an emerging alternative. Longer life expectancy accompanied with increased morbidity, and hospitalisation or dependence on the care of others will contribute to a risk for rapid deterioration of oral health so alternative methods for delivering oral health care to vulnerable individuals for whom access to fixed dental clinics is an obstacle should be considered. The aim was to analyse health economic consequences of domiciliary dental care for elderly nursing home residents in Sweden, compared to dentistry at a fixed clinic. METHODS: A review of relevant literature was undertaken complemented by interviews with nursing home staff, officials at county councils, and academic experts in geriatric dentistry. Domiciliary dental care and fixed clinic care were compared in cost analyses and cost-effectiveness analyses. RESULTS: The mean societal cost of domiciliary dental care for elderly nursing home residents was lower than dental care at a fixed clinic, and it was also considered cost-effective. Lower cost of dental care at a fixed dental clinic was only achieved in a scenario where dental care could not be completed in a domiciliary setting. CONCLUSIONS: Domiciliary dental care for elderly nursing home residents has a lower societal cost and is cost-effective compared to dental care at fixed clinics. To meet current and predicted need for oral health care in the ageing population alternative methods to deliver dental care should be available.
